Notes How Steinbeck develops the character of Curly’s wife Essay

Notes for controlled assessment: Examine how Steinbeck develops the character of Curly’s wife. INTRO. Develops through different themes and emotions through book. Introduced through males eyes negatively. Gives reader impression she is promiscuous and dangerous. ‘Tart, jailbait, tramp. First appearance in book describes her as flirtatious/temptress. As book progresses the views on the character change from initial perception. Tries to exert some power in the hierarchal structure on the ranch (Crooks). Above all is crying out for attention and company, loneliness seals fate. Themes in order: 1. No name/negative image. 2. Attractiveness/attention. 3. Loneliness. 4. Tragedy/victim/women in 1930s. 1. Introduced to the reader through the eyes/opinions of the males. Quote. Not once mentioned to have a name. Defined by her relationship, not an individual. No real meaning, existence no real identity. Disrespectful. Echo’s how women were treated in 1930s hierarchy (explain). No opinions/rights on matters; could’ve led to feelings of loneliness and victim of discrimination. Quote. Is above Crooks & uses that power. Quote. Sausages. Quote. Fashionable but described unattractive & negative. The way in which she talks. Quote. Portrayed as weak & delicate. Powerless. 2. Young. Probably doesn’t intentionally mean to come across as a tramp or tart. Bored, has nobody to talk to. Her sexuality, provocativeness & the way she portrays herself as a temptress leaves her considered dangerous. Attractiveness is her weapon, no use as no one likes her. Wears red. Quote. Red nails. Brazenness. Reminds reader of Weed & foreshadows things to come (death). In red when introduced and red when killed. Change of description at death. Quote. Sweet, young and innocence. Uses it for attention. Gets the wrong kind of attention. All because of loneliness. 3. From the start Steinbeck uses irony. Soledad/Spanish/solitude. Loneliness, isolation & seclusion how she feels. Quote. Wants company, lonely, doesn’t receive love and affection she needs/a young girl would want. Doesn’t understand why nobody will speak with her. Quote. Only female on the ranch. Demonstrates inner feelings, reader sympathises. Quote. In the end finally confides in someone, Lennie, leads to death. 4. Loneliness leads to her tragic death. Possible foreshadowing of death through loneliness- explain. Nobody will talk but then when Lennie does it results in her death Quote in a way putting her out of misery. Introduced as a girl quote no powerful presence from start, girl gives impression of vulnerability. Surrounded by all males/only female on ranch. Death that of tragedy as she tells of bright future promised quote felt betrayed by family to then settle with Curly. Women had no real career opportunities, heartbroken to end up a housewife like the rest, trying to live the ‘American Dream’ had hope and very nearly independence. CONC

Database: Entity-relationship Model

Appendix A: A Practical Guide to Entity-Relationship Modeling A Practical Guide to Entity-Relationship Modeling Il-Yeol Song and Kristin Froehlich College of Information Science and Technology Drexel University Philadelphia, PA 19104 Abstract The Entity-Relationship (ER) model and its accompanying ER diagrams are widely used for database design and Systems Analysis.

The case study will provide readers with a detailed approach to the modeling process and a deeper understanding of data modeling. Introduction Entity relationship diagrams (ERD) are widely used in database design and systems analysis to represent systems or problem domains. The ERD was introduced by Chen (1976) in early 1976. Teorey, Yang, and Fry (1986) present an extended ER model for relational database design.The ERD models a given problem in terms of its essential elements and the interactions between those elements in a problem domain. The ERD can serve as the basis for databases, which store data about the problem domain, and which use, manipulate, and constrain that data. Experts in systems analysis and database design are adept at identifying user requirements and then translating them into corresponding components of the model. Many books and articles just provide a definition of each modeling component and give examples of pre-built ER diagrams. Beginners in data modeling have a great eal of difficulty learning how to approach a given problem, what questions to ask in order to build a model, what rules to use while constructing an ER diagram, and why one diagram is better than another. 213 Appendix A: A Practical Guide to Entity-Relationship Modeling Ahrens and Song (1991) present a set of requirements elicitation template sentences, structured English template sentences, and some decision rules for database modeling. This paper presents a set of heuristic rules which improve upon those presented by Ahrens and Song (1991), together with a detailed case study analysis.We include step-by-step guidelines, a set of decision rules proven to be useful in building ER diagrams, and a case study problem with a preferred answer as well as a set of incorrect diagrams for the problem. These guidelines and decision ru les have been successfully used in our beginning Database Management Systems course for the last eight years. The case study will provide readers with a detailed approach to the modeling process and a deeper understanding of data modeling. The Entity-Relationship Diagram The entity relationship diagram is a graphical representation of a conceptual structure of a problem domain being modeled.The ERD assists the database designer in identifying the data and the rules that will be represented and used in a database. The ERD is an implementation-independent representation of a problem domain and it facilitates communication between the end-user and the analyst. ERDs can be easily converted into a logical database structure that can be readily implemented in a particular commercial database management system. The basic components of the ERD are entities, properties of entities called attributes, and relationships between entities. Entities Entities are PRIMARY THINGS of a problem domain about which users need to record data.Ross (1988) provides a list of candidate entity types which could be included in the model. (1) People: humans who carry out some function Employees, Students, Customers (2) Places: sites or locations Cities, Offices, Routes (3) Things: tangible physical objects Equipment, Products, Buildings (4) Organizations Teams, Suppliers, Departments (5) Events: things that happen to some other entity at a given date and time or as in an ordered sequence Employee promotions, Project phases, Account payments (6) Concepts: intangible ideas used to keep track of business or other activities Projects, Accounts, Complaints 214 stepsAppendix A: A Practical Guide to Entity-Relationship Modeling These candidate entity types need to be evaluated against a particular domain being modeled. Some decision rules are discussed in a later section of this paper. Attributes Attributes are properties of entities or relationships. Entities have two types of properties: identi fying attributes and descriptive attributes. Identifying attributes uniquely determine each instance of an entity type. They are called entity identifiers or keys. For example, the attribute social security number would uniquely identify each member or instance of the entity type student.Descriptive attributes of student might include year, advisor, and grade point average. Each instance of an entity has a value for each attribute. Values for grade point average might include 2. 5, 3. 45, and 4. 0. Values for year might include 1991, 1992, 1993, and 1994. Only attributes that are meaningful in terms of modeling the problem under consideration are included in the ERD. For example, we would not include eye color in a student database. Relationships Relationships are another basic component of the ERD. A relationship is an association between or among things or entities.A relationship describes a meaningful interaction that needs to be remembered by the system. The degree of a relation ship indicates how many entities are participating in the relationship. A unary relationship describes an association of an entity with itself. A binary relationship, the most common instance, describes an association between two entities. A ternary (or n-ary ) relationship is an association between three or more entities. The ER methods that allow only unary and binary relationships are called binary models, while ER methods that allow any type of relationship are called n-ary models.For more thorough treatment of ternary relationships, see Jones and Song (1995, 1996) and Song and Jones (1995). Cardinality and Participation Constraints Cardinality is a constraint on the relationship between two entities. Specifically, the cardinality constraint expresses the maximum number of entities that can be associated with another entity via a relationship. For example, in a binary relationship (a relationship with two participating entities), we can have three possible cardinalities: oneto-o ne (1:1), one-to-many (1:N), or many-to-many (M:N).One-to-one cardinality says that, for entities customer and account, one customer can have at most one account and one account cannot be owned by more than one customer. One-to-many cardinality says that one customer can have many accounts, but one account cannot be owned by more than one customer. Many-to-many cardinality says that one customer can have many accounts and one account may be owned by many customers. 215 Appendix A: A Practical Guide to Entity-Relationship Modeling Participation is also a relationship constraint.Participation expresses the minimum number of entities that can be associated with another entity via a relationship. There are two values for participation: total or mandatory participation and partial or optional participation. If every instance of an entity must participate in a given relationship then that entity has total participation in the relationship. But if every instance need not participate in a g iven relationship then the participation of that entity in the relationship is partial. Given the relationship employee works for epartment, an employee has partial participation in that relationship if he or she need not work for a department. An employee has total participation in the relationship if he or she must work for at least one department. Similarly, a department has partial participation in the relationship if it can exist without having any employees. A department has total participation in the relationship if it must have at least one employee. Cardinality and participation constraints are business rules in the problem domain being modeled. These constraints represent the way one entity type is associated with another entity type.These constraints are also integrity constraints because they help to ensure the accuracy of the database. These constraints limit the ways in which data from different parts of the database can be associated. For example, let's say the cardin ality of the relationship between Customer and Account is one-to-one, as in Figure 1(a) below. If customer C1 is associated with account A3, then C1 cannot be associated with any other accounts and A3 cannot be associated with any other customers. 216 Appendix A: A Practical Guide to Entity-Relationship Modeling (a) One – to – One (1:1):One customer can have at most one account.

Occurrence Diagrams show the relationships between occurrences or instances of each entity. 217 Appendix A: A Practical Guide to Entity-Relationship Modeling Taxonomy in ER Modeling In an ER model, an entity is represented as a rectangle containing the name of the entity. The names of attributes are enclosed in an oval connected to the rectangle of the entity they describe. Attributes may be omitted from the diagram to avoid cluttering it and also in the early stages of development.Relationships are represented by diamonds between entities. The notation of the ERD, however, varies according to the modeling approach used. Binary models do not use the diamond to indicate a relationship, do not represent attributes of relationships, and do not allow ternary relationships, that is, relationships between three or more entities. Martin (1989), Bachman (1992), ERWin and IDEF1X (Bruce, 1992) use the binary modeling approach. Most text books use n-ary modeling, including Elmasri and Navathe (1994), Hawryszkiewycz (1991), Teorey (1994), Batini, Ceri and Navathe (1992), and McFadden and Hoffa (1994).A few notations are illustrated below. n Employee 1 Department a) Chen Employee Department b) Teorey n Employee 1 Department c) Elmasri ; Navathe Employee (0,1) works_for is_worked_for Employee works_for Employee p ——————–works_for Employee c has (1,n) Department d) MERISE Employee Department e) IE Department f) Bachman Department g) IDEF1X Department h) Shlaer & Mellor Figure 2. Various notations for ER Diagram representing â€Å"one employee works for zero or one department and one department has one or more employees†. 218 Appendix A: A Practical Guide to Entity-Relationship ModelingEach diagram in Figure 2 contains two entities: employee and department. In diagrams a, b, c, and d, the diamond indicates the relationship between the entities. T hese diagrams use n-ary modeling. Diagrams e through h are examples of binary modeling. They do not represent the relationship with the diamond shape. Instead, diagrams e, f, and h label the line between the entities with the relationship name. Attributes were not represented in the diagrams for simplicity. The various circles, lines, arrows, and letters on the diagram indicate cardinality and participation constraints.For a more complete treatment of various ER modeling methods, see Song, Evans, and Park (1995). ER Modeling How does one begin creating an entity relationship diagram? In this paper, we present step-by-step guidelines to build an ERD using n-ary modeling using Elmasri and Navathe's notation (see 2. c). In Table 1, we summarize a sequence of steps of database design using an ER model. Note that these steps are iterative. 1. Understand the problem domain. Analyze database requirements. †¢Write a summary specification in English, if not created yet. †¢What do w e need to store into the database? What queries and reports do we need to generate? †¢ What are important people, places, physical things, organizations, events and abstract concepts in the organization? 2. Design a conceptual schema by creating an ER diagram. (a) Identify entity types. Assign a singular noun to each entity type. (b) Identify relationships between (among) entities. Use a meaningful verb for a relationship name. (c) Draw an ERD without attributes. (d) Identify relationship cardinalities. †¢Mapping constraint (1:1, 1:N, N:M) †¢Participation constraint (Total, Partial) (e) Assign attributes to entity types and relationship types.Usually attributes come from nouns, adjectives or adverbs. (f) Select identifiers (primary keys) for entity types. †¢Weak entity: composite primary key. †¢Regular entity: choose/create a single attribute primary key. (g) Select the PKs of relationships. †¢If 1:1, then the PK of either side entity type may be select ed. †¢If 1:N, then the PK of N-side entity type must be selected. †¢ If M:N, then a composite PK consisting of PKs of two entity types must be used. †¢ If ternary, then a composite PK consisting of the PKs of at least two entity types.The actual PKs selected will vary depending on the cardinality. 3. Design a logical schema. (a) Translate the ERD into a relational schema 219 Appendix A: A Practical Guide to Entity-Relationship Modeling †¢If a relationship cardinality is likely to be changed; use stable method. †¢If a relationship cardinality is not likely to be changed; use mapped method. †¢ If a relationship cardinality is not likely to be changed and null values of foreign keys are significant; use mapped with total/partial method. (b) Check normalization (at least 3NF). (c) Create data dictionaries. A schema table †¢One table for each relation created in step (a) – Assign a domain type for each attribute. – Explain the meaning of a ttributes, if not intuitive. – Note other values such as range, null, PK, FK, indexed, source, owner (d) Do database prototyping & modify the design if necessary. (e) Summarize the design assertion (integrity, security). 4. Verify the design with users. Iterate the steps, if necessary. Table 1. Steps to DB Design Using ER Modeling First, it is important to study the problem domain at hand. Analyze database requirements.Write a summary paragraph for the problem domain, considering what data need to be stored and what queries and reports need to be processed. All the information necessary for the identified queries and reports must be included in the summary paragraph. Revise the summary paragraph considering database requirements. Second, from the summary paragraph, find nouns. They are candidates for entity types. To determine whether a noun should be designated as an entity, the following decision rules may be applied. Rule 1 Every entity type should be important in its own right within the problem domain.Rule 2 IF an object type (noun) has only one property to store THEN it is an attribute of another entity type ELSE it is an entity type. Rule 3 IF an object type has only one data instance THEN do not model as an entity type. Rule 4 IF a relationship needs to have a unique identifier 220 Appendix A: A Practical Guide to Entity-Relationship Modeling THEN model it as an entity type. The first three rules are used to evaluate object types or nouns, and the fourth rule is used to evaluate relationships or verbs. Example 1 Address is usually a property of another object type, like customer, vendor, or company.Its existence is less important and not meaningful in its own right within the problem domain. Address should be modeled as an attribute. Example 2 Suppose we are modeling the customers of a company and we want to include the city where each customer resides. If the name of the city is its only attribute, then, following Rule 2, model city as an attri bute not an entity. Similarly, consider the case of modeling employees and their departments. If the only important property of the department is its name, then Rule 2 tells us to model it as an attribute.However, if we need to store additional properties of each department such as projects or total sales, then we should consider modeling it as an entity. Example 3 Consider modeling the activities of a trucking company. Since there is only one instance of the trucking company, then, according to Rule 3, it is not necessary to represent it in our model as an entity. We note that it is not wrong to model this single instance noun as an entity type. We simply do not model it as an entity type at the conceptual level because it does not add any modeling power.We need the fourth rule because one fact can be stated in many different ways in English. In the fourth rule, distinguishing between entities and relationships depends on the function the component plays in the problem domain and h ow data will be stored about it. Example 4 Consider the three statements customer orders products, customer pays bills, and reviewer reviews papers. Even though orders and pays appear to represent relationships, we model them as entities since each instance would need a unique number for identification in real-world situations.Information would be stored in the database for each order and payment. Each review is not likely to need a unique identification number. Instead, we identify each review activity by a combination of Paper# and Reviewer#. Thus, by Rule 4, we model reviews as a relationship type. Once entities have been assigned, we proceed to identify relationship types between those entities. Verbs are useful candidates for relationships. The following question is useful for identifying relationships: â€Å"What sentences can be constructed of the form Entity Verb Entity? † For example, 221Appendix A: A Practical Guide to Entity-Relationship Modeling †¢Employee ha s children (Existence relationship) †¢Professor teaches students (Functional relationship) †¢Customer places order (Event relationship) Note that a relationship is not an action of a flow of data as in data flow diagrams. They are important interactions, between two or more entities, that need to be remembered by the system. In the above examples, we want to remember the facts that who is a child of which employee, which professor teaches which students, and which customer places which order. Also keep in mind that all relationships are bi-directional.We should be able to state the relationship in both directions. Expressing the relationships above in the opposite direction yields the following statements: †¢ Children belong to employee †¢ Students are taught by professor †¢ Order is placed by customer After an ERD has been built, the following rule can aid in validating the diagram. Rule 5 IF any verb refers to nouns which are not selected as entity types T HEN do not model it as a relationship type. If any verb in the ERD fails to follow Rule 5, then consider it again carefully before including it in the diagram.When entities and relationships have been identified, then the cardinality and participation constraints of the relationships can be analyzed. The following rules can help determine the cardinality and participation constraints for a given binary relationship. A B Rule 6 For each A, what is the maximum number of Bs that may be related to it? Rule 7 IF A can exist without being associated with a B THEN A has partial (optional) participation ELSE A has total (mandatory) participation. 222 Appendix A: A Practical Guide to Entity-Relationship Modeling Example 5 Consider the relationship Supplier Supplies Account.For each Supplier, what is the maximum number of Accounts that may be related to it? Let's say that in our problem domain, each Supplier may have many Accounts but each Account may have only one Supplier. By Rule 6, the ca rdinality constraint for Supplier:Account is 1:N or one to many. Figure 1 illustrates the cardinality constraints. Example 6 In determining the participation constraint of Supplier Supplies Account, we follow Rule 7: If Supplier can exist without being associated with Account, THEN Supplier has partial participation, ELSE Supplier has total participation.In our problem domain, Supplier may exist without being associated with Account. Therefore, Supplier has partial participation in the Supply relationship. However, since Account cannot exist without a Supplier; Account has total participation in the Supply relationship. Some basic naming conventions have been established to maintain accuracy and consistency in the database and to avoid redundancy. All entity names should be unique. Use singular nouns in the diagram for both entity and attribute names. Use verbs in the present tense for relationship names. Verbs should be meaningful.For example, avoid verbs like is, has, and do whene ver possible. Additionally, well-defined ERDs should satisfy the following basic rules: †¢ All entities and relationships should be connected. †¢ All entity names should be unique. †¢ Each entity must have at least one relationship. †¢ A relationship cannot be directly connected to another relationship. †¢ Every entity must have at least one unique attribute, which serves to identify each instance of that entity. Case Study The following example will illustrate our guidelines for modeling requirements of the problem domain with entity-relationship diagrams.Using the summary paragraph of the problem description below, we will progress through the steps described above. The nouns in the problem description appear in boldface and the verbs are italicized to aid in the following analysis. Summary Paragraph of Problem Description A database specialist wants to design a part of the database for a small drug store owner as follows: The owner wants to keep track of all the suppliers who supply anything to the store. For each supplier, the owner assigns a unique supplier number, and wants to keep the 223Appendix A: A Practical Guide to Entity-Relationship Modeling company name, address (number, street, city, state, zip), contact person's name, phone number, fax number, and a comment for each supplier. For each supply activity, an account is established to keep track of the date incurred, the total cost of the activity, due date for payment, outstanding balance after some payments, and any special comments related to the account. For each account, the owner may pay at several different times and in different ways (e. g. , cash, check, credit card).For each payment activity, the owner wants to keep the date of payment, amount of payment, method of payment (check: check number; credit card: credit card name, type, and number). Note that one supplier can supply many times and one payment can pay for several accounts of the same supplier. Entity Ana lysis After reading and understanding the problem statement, our first step is to identify entities for the ERD. To do that we examine the nouns in the problem statement. Nouns appear in boldface. We test each noun against our four criteria to determine whether or not it should be included as an entity type.Our first noun is owner. Recall that an entity type has more than one instance and more than one property. Since there is only one instance of owner, we do not model it as an entity type. Similarly, there is only one store, so we need not represent store as an entity type. The next noun, supplier, can be classified as an entity type. Several properties of supplier are listed in the problem statement. The statement also refers to more than one supplier. Therefore, according to Rules 1, 2, and 3, we model supplier as an entity.For each supplier, the owner wants to store the following properties in the database: supplier number, company name, contact person, address, phone number, f ax number, and comment. Each of these attributes except address has only one property to store so we model them as attributes. Address has its component properties number, city, state, and zip so one might be tempted to model it as an entity type. However, the role of address as a property of supplier supersedes the fact that address has properties of its own. In other words, address itself without supplier is not important in its own right.Therefore, by Rule 1, we model address as an attribute. Account is the next noun. Account has several properties to be stored in the database: date incurred, total cost, due date, account balance, and comments; and we will store information about numerous accounts. Therefore, we designate account as an entity. Its properties are modeled as attributes of account. Payment is clearly an entity, with multiple instances and various properties. The properties of payment: date of payment, amount of payment, and method of payment, are modeled as its attr ibutes.Cash, check, and credit card appear to be attributes of payment, but actually, they are not attributes themselves, but simply different values for the attribute method of payment. This distinction becomes clearer if we think about 224 Appendix A: A Practical Guide to Entity-Relationship Modeling storing data in the database. For each payment, one of the values cash, check, or credit card will be stored in the location containing data about the method of payment. Check number and credit card name, type and number may be modeled as attributes of Payment. Supplier Account Payment Figure 3. Entities to be included in the ERD.Relationship Analysis Our analysis of nouns in the problem statement has produced three entities: Supplier, Account, and Payment (Figure 3). Keep these entities in mind as we identify relationships between them. Let's examine the verbs in the problem statement as candidates for relationships in the diagram. Verbs appear in italics. Of the verbs in the problem statement: keep track, assigns, supply, established, and pay, only supply and pay are possible candidates for relationships between the entities account, supplier, and payment. Keep track and keep appear several times in the problem statement.These terms refer, not to a relationship between entities, but generally to storing data in the database. In other words, they are used to describe the problem domain, not an interaction that needs to be remembered by the system. Therefore, we do not model them as relationships. Established, in the statement an account is established, is an activity performed by the owner or the system itself. Similarly, owner assigns a unique supplier number reflects an activity by the owner. These two verbs do not represent relationships between any of our three entities. Thus, we are left with the verbs supply and pay.A supplier performs a supply activity. The result of a supply activity is an account. Therefore, a good candidate for the relationship betwee n supplier and account is supply. Stated in both directions, the relationship is Supplier supplies account and account is supplied by supplier. Rule 4 states that if a relationship needs to have a unique identifier, then model it as an entity. Each supply activity is unique, so we may be tempted to model supply as an entity. However, the data for each activity is stored using the entity account, so it is not necessary to create another entity which stores the same information.Each payment credits an account so pay is the relationship between payment and account. Expressing the relationship pay in both directions, we can say account is paid by payment and payment pays account. 225 Appendix A: A Practical Guide to Entity-Relationship Modeling Now we can draw the basic ERD (Figure 4). We include the entities Supplier, Account, and Payment, and the relationships Supply and Pay. Attributes may be added to the diagram at this point or omitted to avoid clutter. Supplier Supply Account Pay Payment Figure 4. ERD without attributes and constraintsAnalysis of Cardinality and Participation Constraints In order to identify the cardinality and participation constraints of each relationship in the ERD, we follow Rules 6 and 7 looking at the relationship first from the point of view of one entity and then from the other entity. In our ERD above, to determine the cardinality constraint of the relationship Supply, we begin by asking, â€Å"For each Supplier, what is the maximum number of Accounts that may be created? † From the problem statement, we know that one supplier can supply many times and an account is established for each supply activity.Viewing the relationship in the other direction, we ask, â€Å"What is the maximum number of Suppliers for which each Account may contain information? † From the problem statement we can assume that each account carries information for a single supplier, since accounts are established for individual supply activities. Th us, for each supplier, there may be many accounts and each account may have only one supplier. The relationship Supplier Supplies Account is a one-to-many relationship. The diagram is marked with a 1 on the side of the relationship Supply nearer to Supplier, and an N (for many) on the side nearer to Account (see Figure 5).To identify the cardinality of the relationship Payment Pays Account, we look at the relationship from both directions. We ask, â€Å"What is the maximum number of Payments we can accept for each Account? † The answer is clearly stated in the problem statement: For each account, the owner may pay at several different times and in different ways. From the opposite direction, â€Å"For each Payment, what is the maximum number of Accounts for which it may pay? † Again, we find the answer in the problem statement: One payment can pay for several accounts of the same supplier. In sum, each account 226Appendix A: A Practical Guide to Entity-Relationship Mod eling may receive many payments and each payment may pay for many accounts. Therefore, the relationship Payment Pays Account is many-to-many. This time, we mark our diagram with an M on one side of the relationship Pay and an N on the other side. (Note that the use of M or N is completely arbitrary. ) We go through a similar process to determine the participation constraint of each relationship, looking at the relationship from each direction. For the Supply relationship we ask, â€Å"Can a Supplier exist without generating Accounts? In the other direction, â€Å"Can an Account exist without having Suppliers supply merchandise? † The answers to these questions are not explicit in the problem statement. In a real world situation, the database designers would clarify questions like these with the owner. In this case, we will make assumptions from what we understand about the problem domain. Suppliers are generally fairly stable entities. A company maintains relationships with several regular suppliers regardless of whether they have outstanding accounts. On the other hand, an account is only created when a supplier supplies merchandise.Since suppliers can exist without having current accounts, Supplier has partial participation in the Supply relationship. Accounts, however, depend on suppliers for their existence. Thus, Account has total participation in the Supply relationship. To determine the participation of the entities Payment and Account in the Pay relationship, we ask, â€Å"Can a Payment exist without paying for an Account ? † and â€Å"Can an Account exist without receiving Payments against it? † A payment which pays for nothing is absurd. It cannot exist without an account. An account, however, may exist without receiving payments against it.Therefore, Payment has total participation and Account has partial participation in the relationship Pay. In representing the cardinality and participation constraints described above in our ERD, we will employ Elmasri and Navathe's (1994) notation. If an entity has partial participation in the relationship, then a single line is drawn on the line between that entity and the relationship. A double line indicates total participation. The cardinality constraint is represented by Look Across convention, while participation constraint is represented by Look Here convention.Figure 5 illustrates the final ERD with cardinality and participation constraints. 227 Appendix A: A Practical Guide to Entity-Relationship Modeling 1 Supplier Supply N Account M Pay N Payment Figure 5. ERD with cardinality and participation constraints. Errors in Modeling A common error that novice designers make is failing to recognize the boundaries of a problem domain. They fail to make a distinction between elements that comprise the content of the database and elements that are outside the scope of the database. For example, in the problem statement bove, a novice might want to model the verbs keep track or assigns or established as relationships (see Figure 6(a)). These verbs refer to implementing the database and not to its content. Keep track refers to storing data in the database, established refers to adding an instance of an entity to the database, and assigns refers to giving a value to an attribute of an entity. In deciding which elements to model, it is valuable to keep in mind the real world situation. Novice designers also frequently confuse entities with their attributes or properties, as in Figure 6(b).Occasionally, if properties are complex and play a significant role in the problem domain, then they may be modeled as entities. More often, however, properties of an entity should be modeled as attributes. In our problem statement, a novice user may decide to model address, a property of the entity supplier, as an entity. Modeling Address follows Rules 2 and 3 about identifying entities: it has more than one property and it has more than one occurrence. However, ad dress does not follow Rule1 in that it is not important in its own right.The role of address in the database is more accurate as an attribute of supplier, than as an entity with its own relationships. Other errors are modeling indirect or redundant relationships and inappropriately modeling object types as relationships rather than as entities. Given our problem statement, one may be tempted to model the relationship Payment Pays Supplier as in Figure 6(c) or Supplier Pays Account as in Figure 6(d) rather than Payment Pays Account. Figure 6(c) represents the association between payment and account indirectly. This indirect relationship can only exist after we have all the direct 228Appendix A: A Practical Guide to Entity-Relationship Modeling relationships as in Figure 5. In this case, the indirect relationship simply becomes redundant. Without the direct relationships, the indirect relationship cannot be added, because it cannot explain how a particular payment is distributed to mu ltiple accounts. Figure 6(d) represents the relationship Pay rather than the entity Payment. In either of these two cases, it is difficult to explicitly represent the fact that one payment can pay for several accounts of the same supplier. We can only tell implicitly by reading the check number for the various payments.If the payment is made in cash, there is no way to identify that it paid for more than one account. If the representation used in Figure 6(d) is used, then the attributes related to payments: date of payment, amount of payment, and method of payment, are now attributes of the relationship Pay. This representation can add unnecessary complexity to the model. Ordinarily, a relationship is uniquely represented by the identifiers of one or more of the entities which participate in it. If the relationship includes a time-dependent attribute like date of payment, then that attribute must also be included in the primary key for that relationship.Additionally, instances of da te of payment and amount of payment will require redundant representation because they will have to be included for each account covered by a payment. Finally, in business practice, each payment activity usually requires a unique identifier. Therefore, following Rule 4, it is more appropriate to model payment as an entity than as a relationship. As an entity, the representation is more straightforward and less likely to include redundant or inaccurate information. 229 Appendix A: A Practical Guide to Entity-Relationship Modeling a) Selection of wrong verb as relationship Owner (b) Attribute as entity Supplier Located_at Address Keeps_track Payment (c) Indirect relationship Payment Pays Supplier Establishes Account (d) Payment as relationship instead of entity Establishes Supplier Pays Account Figure 6. Errors in ERD Modeling. Limitations of Guidelines and Rules Two limitations of our guidelines are that they don't account for incomplete requirements analysis or for ambiguity in the problem description. If the problem description is incomplete, then the resulting analysis based on this approach will also be incomplete.We assume that the analysis is complete. If the problem specification is modified, the analysis and resulting ERD should be modified as well. In English, one concept can be represented in many different ways. For example, we can say that customer orders products or customer places an order to buy products. Order is used 230 Appendix A: A Practical Guide to Entity-Relationship Modeling as a verb in the first sentence and as a noun in the second. We minimize this problem by adopting Rule 4, which states that if a verb needs to have a unique identifier, we model it as an entity type rather than a relationship type.Conclusion We have discussed a set of decision rules which are useful in building ERDs and have illustrated the application of these rules using a single example. ERD constructs discussed here include Entities, Relationships, Attributes, Ca rdinality constraints and Participation constraints. To simplify our discussion, we didn't include other constructs such as Weak Entity, Ternary Relationship, and Generalization/ Specialization. Our rules are heuristics which we have found useful for most cases to build ERDs in the early stages of analysis.However, these rules may need some refinement in some problem domains and the rules should be adapted to the problem domain under consideration.

College Campus Essay

In this assignment we are going to design a campus network. Delta Community College (DCC) is a small college. It is attended by 600 full and part time students. The students do not live on campus. There are three dormitories for the students and each dorm can accommodate 400 students. Distance from the college campus to the dorms are: †¢ Dorm1 College Campus = 22KM †¢ Dorm2 College Campus = 5KM †¢ Dorm3 College Campus = 15KM Numbers of students are expected to be doubled every 4 years. There are 4 departments: †¢ Arts and Humanities †¢ Business †¢ Social Sciences †¢ Mathematics. Every department has an average of 150 Students and an average of 10 professors each. There are approximately 20 Administrative personnel available. It is expected that everyone in the college should get access to the network. Students when they are in the dormitory should also get access to the college network. We need to design a computer network so that it is good for next 4 years. Now do the following: A. Every department and dormitory should be put on their own subnet. When you design the subnetting make sure your design support the following: 10 Points i. 3 subnets for 3 dorms each should support 400 hosts ii. Different subnets for 4 departments †¢ Students and professors should be in different subnets. There are 300 students and 10 professors per department iii. A subnet for administrative department which should support at least 30 hosts The assigned IP address is 10. 5. 3. 0/20. So do you think using this IP address we can design all the necessary subnets with at least the required numbers of hosts? If yes then design the subnet structure by showing the assigned IP address range for every subnet. If no then say why. B. Apply a hierarchical approach to design this network. Your design should include:7 Points i. Core Layer ii. Distribution Layer iii. Access Layer In the designed network you need to mention what network device such as: cables, hubs, switches, routers etc. you are going to include in each layer. C. Dormitories are connected to the campus network via Single Mode Fiber Optic Cable. Because of attenuation loss we need to splice the fiber optic cable every 10km. if the splicing loss is: 0. 35dB then find out total splicing loss for every connection to each dormitory. 3 Points Note: There is at least 500m distance from the main server to different departments. So choose proper cabling when you connect the departments to the main server.

Having good manners is important to everyone Essay

The subject of my presentation is Having good manners is important to everyone especially in today’s society. It should not matter whether a person is at home, work, or just hanging out with friends; manners are always important in all that a person does. Your manners are important all of the time. It is possible to manners in the way a person walks, talks. However sometimes good manners are regarded as old-fashioned, something that are now out of date and unnecessary. It is true that opening doors for each other, waiting our turn to be served, often seems to be a thing of the past. Good manners provide a moment in time where someone stops and considers our needs, offers us a seat, asks us politely for something with a ‘please’ and says ‘thank you’ afterwards. These niceties may only take a second, but they are an important second in our busy world of rushing around, solely thinking of ourselves and what we need to do. Those moments can make us stop and consider the importance of noticing the other person, the waitress, the sales person. Do we really need to bark out our orders, demands? How much more pleasant would it be for all concerned if we asked for something politely, with a ‘please’ at the end of the request. And acknowledged receipt of it with a smile and a ‘thank you’. Road rage is evidence of extreme bad manners, which usually involves one person driving inconsiderately. Good manners are about appreciating that life is not all about us and what we want. Our needs have to be negotiated along with everyone else’. Now I would like to tell you the examples of the importance of good manners. First, Thank you letters are important. Whether someone has sent a gift or entertained you at their home, it is important to acknowledge their effort and thoughtfulness. They have done something special for you and a handwritten note or letter shows that you are prepared to respond and take the time to value what they have done and thank them for it. Writing a thank you letter is an important skill to learn. Constructing an effective letter, with good grammar and an important message is a valuable skill to have, and one that is rarely taught in these days of rapid texting and instant messaging. Next, saying ‘please’ and ‘thank you’ to the people we deal  with when we want or need something is basic good manners. And ‘excuse me’ if we sneeze or cough, covering our mouth with a tissue. Holding the door open for someone else, offering an elderly person or a pregnant lady a seat are good manners but they are also demonstrating respect, empathy and consideration for the other person. A simple gesture like that can improve the mood and quality of someones’ day. But it is important to be respectful back and return the compliment with a simple thank you or a smile. Good manners are a two-way exchange. Even if we do not respect the person sometimes good manners are about respecting their position or status and what that represents. We may respect the fact that someone is a manager or a school teacher or highly educated and when they are in that role we moderate our behavior towards them and give them respect out of deference for their position.

Blame in Romeo and Juliet Essay

In the play â€Å"Romeo and Juliet† a series of unfortunate the circumstances and illogical decisions force the protagonists into an impossible position ultimately resulting in their death. As Il-fated as the two â€Å"star-crossed lover’s† may have been the root of all their problems can be traced back to rash decisions by characters and circumstances placed unfairly on characters by warped societal expectations. While the Friar had nothing but the best intentions his illogical and somewhat naive decisions contributed greatly to the tragedy of Romeo and Juliet. Romeo’s impulsive, dangerous and irrational behavior is also to blame. Societal expectations and outside influences can be partly to blame for many of the characters irrational decisions. Although these expectations could be to blame for two lovers parents behavior it does not justify them completely, thus they are also to blame. None of these reasons can be blamed in isolation but all contributed to the ultimate outcome of Romeo and Juliets relationship. The Friar was very mush to blame for the tragic outcome of Romeo and Juliet. He was continuously relied on for advice from Romeo and Juliet and failed to acknowledge his mistakes after their deaths. The Friar is blame because he married the two with their parents consent and thought that Romeo’s love lied â€Å" not truly in [his] heart, but in [his] eyes†. Instead he foolishly chose to marry the two, purely â€Å"to turn [their] households’ rancor to pure love† despite being unknowing of the true nature of their dispute as a priest. Not only this, but he also expressed that things were moving too fast and that â€Å"violent delights (such as Romeo’s and Juliet’s love) have violent ends† but continued with the wedding anyway. He failed to listen to his own wisdom and take things â€Å"wisely and slowly†. Despite prolonging the lives of two suicidal teenagers, they placed their trust in him when he promised to â€Å"blaze [their] marriage†¦beg pardon to the Prince, and call thee back†. Because he made no attempt at doing so, he instilled false hope into the couple, which also contributed to their deaths. Furthermore he failed to personally deliver the letter explaining Juliet’s faked death to Romeo, instead outsourcing it to another Friar without telling him of its urgency. This lack of responsibility repeats itself when he gives an unstable, teenage girl a fake-death poison, a risky idea he should have known better not to do. Furthermore, he leaves Juliet when she is at her most vulnerable,  alone together with her dead husband. Because he was the only adult Romeo could trust, the Friar’s naive, rash and immature decisions that neglected to look after Romeo and Juliet properly were at the epicenter for why their deaths occurred. The melodramatic character of Romeo is also very much to blame for his fate because of his impulsive decisions and his inability to control his emotions. Mature enough to show genuine love for Juliet he is unable to make logical decisions. Although he showed enough common sense to avoid a fight with Tybalt it is clear that when misfortune swallows Romeo he becomes an impulsive and somewhat selfish person, valuing his own pride over a life together with Juliet. His immaturity is illustrated when he describes himself as â€Å"fortunes fool† or saying that Juliet made him weak, as he is merely passing the blame along rather than accepting full responsibility. It is obvious that because of Romeo’s weakness, Juliet suffers too. Whether it is taking a potion or killing herself she continuously risks her neck to help undo her husband’s wrongdoings. In Friar Laurence’s words Romeo â€Å"is set afire by thine own ignorance†¦ like powder in a skill-less soldiers flask.† By climbing the Capulet’s walls, marrying Juliet within days, killing Tybalt and himself, his lack of foresight and awareness of how his actions affected others ultimately lead to Juliet’s and his own death. The pressures and expectations formed and enforced by society, forced the characters, into impossible situations, which forced difficult and risky decisions. The Patriarchal society meant women such as Juliet had no voice in things such as their own marriage. This, coupled with the unjustified conflict in Verona meant that Juliet was unable to Marry in public, which set off a chain of events ultimately leading to her death. These same values forced Romeo into conflict with the malevolent Tybalt. At first he eludes fighting, telling Tybalt that he â€Å"loves thee better than thou cant devise† but despite being loving person at heart the patriarchal society which promoted masculinity acted as a catalyst for Romeos impulsive character. The corrupting influence of this societal value forced Romeo to maintain honor and revenge Tybalt because Juliet â€Å"made him effeminate† or weak like a women. Furthermore the societal values of loyalty to one family meant pride  alone kept the futile conflict a part of everyone’s lives. Because of this and the need to respect ones elders unconditionally it meant that Romeo and Juliet were not able to stand up to their parents and declare the marriage public. When Juliet showed any sort of rebellion toward her parent regarding marriage she was abused and practically disown. Even after this loyalty to her family influenced Juliet to use â€Å" a thing like death† in order to be with Romeo and â€Å"to ‘scape from (the shame)† that would come with running away from her family. The Parents of Romeo and Juliet are also to blame because as adults they should have showed maturity and put away their pride like the youthful Romeo and Juliet and put an end to the unjustified conflict. Firstly Capulet directly influences the outcome by forcing the marriage between Juliet and Paris despite Juliet’s obvious discomfort. But as adults they had the greater responsibility of putting an end to the conflict but quite to the contrary they were seen encouraging and wanting to actively engage in it when the fight broke out between rival servants. The reason for the tragedy cannot be blamed on fate because the environment that the parents created meant that their whole love affair was doomed from the beginning. There was no-way their marriage in secret could last forever because enviably Juliet would be forced to marry somebody else. The hope, which the youthfulness of Romeo and Juliet embodied, was foiled by the reality created by their parents. Without this mutual ha ted the fight between Tybalt and Mercutio would not have occurred, and there would be no issue marrying Romeo thus the outcome of the play can be directly attributed to the conflict instilled in society by the parents of Romeo and Juliet. In the play a series of unfortunate situations and illogical decisions by characters create a downhill spiral, which escalates ultimately to the death of Romeo and Juliet. The Friar can be regarded as the character that should have and did know better but failed to act accordingly. While Romeo blinded by emotions failed to make logical decisions or take into account the impact they had on others. These characters were put under unnecessary pressure by social expectations that existed primly because the parents of Romeo and Juliet failed to stop the unjustified conflict in Verona. None of these  factors can be blamed in isolation they all were pivotal causes of the tragedy of Romeo and Juliet.

Compare and contrast Christianity, Judaism, and Zoroastranism Essay

Compare and contrast Christianity, Judaism, and Zoroastranism - Essay Example To begin with, it must be noted that all three religions in question are monotheistic (Fisher, 2014). Indeed, it must be noted that several thousand years ago, the majority of religions that were spread in the world were polytheistic; that is why faith in one God should be seen as a rather progressive worldview. Thus, in the set of religious coordinates, Ahura Mazda is the supreme God that people should worship. In the view of Judaism, there is also one God that freed this nation from slavery in Egypt and led them to the Promised Land. Finally, Christianity is also monotheistic religion; however, it features the so-called Trinitarian monotheism which stands for one God in Three Persons. So, one might suggest that the first feature that these religions share is belief in one God. The second aspect that should be taken into account is the afterlife. Thus, Zoroastrianism, Judaism and Christianity believe that after death the soul of a person does not disappear, but goes to a different world. According to the former religion, the conditions in which a soul will find itself after death are determined by the manner on the early life. As one can clearly see, there is a similar aspect in Christianity when our deeds determine our afterlife. It must be noted that the position of Judaism on the issue of afterlife is not fully determined, but it would not be a mistake to suggest that as a religion it fully rejects it. That is why the existence of afterlife is another point that these religions share. Finally, the common ground of Zoroastrianism, Judaism and Christianity may also be found in what is usually referred to as the Golden Rule. In spite of the fact that I may be formulated in different ways, the original message behind it is similar: one should treat others in a way one wants to be treated. There is no doubt that this is a rather

Perfectly competitive markets Essay Example | Topics and Well Written Essays - 1500 words

Perfectly competitive markets - Essay Example No seller has a bargaining power over another because the products sold in perfectly competitive markets are assumed to be homogenous in nature. Lastly, the motives of the seller participants is maximization of profit, hence they sell where marginal revenues equal the marginal cost. From these characteristics is driven the 'price taker' nature of firms in the market. Hence it is safely inferred that in such markets the prices set by individual firms and the industry are same; and is determined by the interaction of total market demand and total market supply. The prices set by individual firms and the industry is same; and is determined by the interaction of total market demand and total market supply. From the above graph, it is visible that when both quantity demanded and quantity supplied is at the same level i.e. 800 kgs, there the market will reach equilibrium. At that point, the equilibrium price is $11 per kg. The prices of products are impacted either by a change in the demand of that product, or when the supply of that particular product changes. Bade, Parkin and Wesley (2008) said on the demand side, the change in demand factors including changes in consumer tastes by preferring a certain product over another, when then is an increase in the number of buyers for the product, or when income of the buyer changes (increases or decreases) depending on whether the product is normal good or inferior good. The change in the prices of related products also impacts the demand. On the supply side resource prices, technology, taxes and subsidies, prices of other goods and anticipation of future price changes and the number of suppliers affect the supply. Cyclone Larry increased the price of bananas because it wiped out the banana crop in Queensland, which reduced the quantity supplied of bananas into the market, hence a movement on the supply curve; which led to the increase in the prices of bananas. Price Quantity Supplied Quantity Demanded in A $ in kgs in kgs 15 1000 400 13 900 600 11 800 800 9 700 900 8 600 1100 7 0 1300 6 0 1600 In the diagram, we can see that at $ 15, the quantity demanded is less than quantity supplied, which means 'many consumers could not afford to buy them'. Question 3: In controlling the price of bananas, which have reached a certain high and is unaffordable for consumers, the government intervenes to control the prices that it thinks are unfavorably high for the buyers. Thus, using its legal right, government limits the high prices by imposing the price ceiling (Lipsey & Chrystal, 2007). Here, we demonstrate the impact of price ceilings graphically. In our case, Cyclone Larry has adversely impacted the crop of bananas, and has reduced the supply of bananas. At this level, quantity demanded increases relative to quantity supplied. This increases the equilibrium or the market price. This rapidly rising prices of bananas greatly burdens low and moderate income house holds , which leds government to intervene for making it affordable for the masses. It imposes a ceiling price of A $ 8 per kg. For this to be effective, the price ceiling is less than the equilibrium price, which in our example as earlier

Can you follow the reasoning of the Fine Tuning Argument Are you Essay

Can you follow the reasoning of the Fine Tuning Argument Are you convinced by it's reasoning and it's response to many universes hypotheses Why or why not - Essay Example Everyday science is discovering new things, so it would be inadequate to conclude that God is omnipotent. This is a response to the reasoning and responses to the universe hypotheses of the fine tuning argument (Collins, 3) I am not convinced by the general principle reasoning. It formulates the fine tuning argument against the ‘atheistic Single-universe’ hypothesis. It uses the prime principle of confirmation. The confirmation principle states that for two hypotheses H1 and H2. Something counts as evidence for hypotheses rather than another that is when is truer under a certain hypothesis than another (Collins, 8). Therefore in probability, the greater the difference, the greater the probability of counting as evidence. The examples offered in the principle of confirmation are, firstly, find rocks. Whereby if you find rocks in the mountain errand Saying ‘welcome to mountains’ there is a great probability that it is your brother who wrote it rather than chance. Secondly, a defendants fingerprints found on a murder weapon would more probably suggest that he is the murderer. I do not agree to the application of the principles that relies on the fact that that the universe has th e fine-tuned life factors being more probable under the theism hypothesis. The belief that the universe along with the essential life factor is an inexplicable brute fact (Collins, 18). The principle questions whether there are other universes. If there are, then one of the universes has to be fine tuned. It happens that the only fine-tuned universe could be ours because the other does not support an intelligent life. I am not convinced by the response to many universes hypothesis because it describes the universe as large or perhaps infinite thus it differs with the fundamental physical parameters. I agree that the majority of the universes do not support life-permitting values only a one. Its hard to understand the existence of improbable universe such

Alexander the Great & His Glorious Battles Research Paper

Alexander the Great & His Glorious Battles - Research Paper Example ... It was not the Macedonian Phalanx which penetrated to India, but Alexander." The terms like ‘brilliant’ and Genius† truly represented the character of Alexander. According to Major General J.F.C. Fuller, only a genius â€Å"binds the Great Captains into a common brotherhood.† Alexander’s greatness could be seen in his genius through his visibility, physical and moral bravery, strength, aspirations to materialize the dreams he had, purposefulness, triumphs and accomplishments, which created a feeling of appreciation, reverence, safety and respect among his forces. ? Napoleon Bonaparte was a great admirer of Alexander the great. If one wants to learn the art of war, one should read time and again the war initiatives of Alexander. Alexander was supreme on two fronts, head of the army and political head of the state of Macedonia and knew well that military pursuits were just the tools to achieve political aim of long term peace. Alexander was great be cause he had the insight of using military might and political insight not to indulge in mass killing of enemy forces, a popular perspective of indulging in wars as impressed upon by Clausewitz during the nineteenth century. Alexander pursued a cherished mission of winning the enemy not by looting enemy wealth to bereft the future victorious lands of all the necessary resources or earn the anger and wrath of the enemies unnecessarily. The primary mission of waging wars against foreign lands was to strategically win the confidence of the people through political maneuvering.? The principles followed by Alexander helped in his winning adventures, which included respect for energy, attention, fast turnaround time, sudden action, and cherishing the mission. Alexander had deep understanding of other strategically crucial warfare elements such as playing offensive tactics, using the military power economically, and setting up of safer bases, and risk-free communications. ? The glorious ba ttles fought by Alexander attached the title of â€Å"great† to his name because he fought the battles by adhering to warfare principles, as stated above. He fought different warfare by following a line of thought in leading battles, sieges, small aggressions, guerrilla war tactics, and revolts, making him distinct from other great commanders. Military commanders in his army were adapted in fighting a traditional war fought openly, they were not expert in the guerrilla warfare designs or circumventing the enemy base. Special about Alexander’s battles was that he never lost a battle during the 10 years war adventures initiated between 335 and 325 BC. He regularly led the warfare during his battles at least once a year, each year. His army was very well trained and full of vigor combined-arms army, gifted to him by his father, to complete arduous tasks whatever the circumstances. Alexander’s army was the unparalleled army of that time. ? Alexander took good care o f his soldiers. He never considered them like paid laborers but always boosted their morale by setting an example of bravery before them through his individual power. He did not expect them to accomplish what he himself could not. He set an example of team-spirit in the army unit, and did not let any opportunity miss for the welfare of his soldiers. His humanistic attitude towards his comrades and appreciation of those in front of the whole unit who have set examples of

Master Plan for Training and Capacity Building of Staff Outline

Master Plan for Training and Capacity Building of Staff - Outline Example It is said so because need analysis defines the gap which exists between current and desired state of organizational and individual performance. The basic purpose of conducting need analysis is to measure the performance and resolving issues related to performance or in case of introducing new technology, task or system or a when an organization desires to take advantage out of an opportunity. There are several ways of providing training to employees in order to polish and sharpen their performance. Some of these methodologies should be included by the firm as training programs in order to build the working capacity of employees. Off-the-job training includes activities through which employee can get training by being out of the workplace. Distance learning, working day releases, self study, sponsored courses are some examples of off-the-job training which must be included while designing a master plan. Appraisal reviews helps in knowing what types of penetrations and variations are required to be included in the training program. Feedback of workers and employees can help in developing a genuine and constructive appraisal review. Difficulty Analysis is commenced in order to determine which type of tasks cause greatest amount of difficulties to employee and how they can be resolved through better training. Difficulty analysis is constructive in enabling the need analysis to weigh different aspects of training in relation to reducing the trouble that the workers might face. Motivation is vital for employee development and capacity building. Intrinsic motivation depends on self esteem, self confidence etc. Individual program should be made in order to deal with employees separately as every other person has different level of intrinsic motivation. Individual employees program should stress on the importance of skills, attitude and other assets that can boost the confidence of employee.

How Might Different Types of Offenders Best Be Deterred From Crime Essay

How Might Different Types of Offenders Best Be Deterred From Crime - Essay Example Therefore with the use of rational theory, criminologists often assume that those who commit criminal acts had the option of rationalizing their decision against those of the basic social norms. For one reason or another they chose to commit a crime but again, this theory depicts the fact that it was their choice, they were not forced to do so (Blossfield & Prein 1998, p.5). Of course, rational theory is neither a sociological nor a criminological theory that can be used to analyze all offenders because there are relative differences between individuals, even those who commit crime. Let's take for instance criminals who engage in white collar crime. This form of crime is concisely opposite crimes that include acts of brutal murder, rape, and kidnapping, etc. The reason this is stated is this form of crime takes initiative on the criminals' part and in fact they rationalize their choices before they ever break the law. Therefore, because these types of offender's are generally rational in their though processes and in their actions to engage in criminal activity, law enforcement would have to use a varied deterrence technique to try and sway and deter this types of offenders from repeating their criminal intentions and also to prosecute them correctly through the judicial system (Uggen & Piliavin 1998). It has been found that because these types of offen ders think logically and weigh the consequences of their actions the more traditional forms of law enforcement work well to keep them and others from becoming repetitive in their criminal attitudes. Law enforcement officials have learned that when a white collar criminal is prosecuted and punished severely for their actions it often acts as a deterrent in society, such as with the Martha Stewart case and the issue with falsifying documents on the stock market, etc. Once one white collar crime is prosecuted correctly it minimizes how many more there would be to follow, there is no doubt about this. In cases of criminal violence and murder, the use of deterrents would of course not be the same as the one's used for white collar crime, simply because of the variations to the types of crime in particular. For example, prosecution of someone who commits murder is definitely not enough of a legal influence to prevent other violent offenders from committing this same form of crime. What it can do however is prevent that one individual from going out and committing the same type of violent act, but again it won't persuade other offenders who have not been caught and faced punishment themselves (Uggen & Piliavin 1998). However, for those criminals who don't seem to be able to rationalize their own actions it has been found that the best way to deter them from being repeat offenders is by incarceration because releasing them back into society has shown that there is a great risk of them repeating their actions. This is all in how they view their behavior and don't think logically such a s how an offender of white collar crime analyzes their own actions. White collar offenders weigh the pro's and cons of their actions that are going to take place. If they find that the consequences will be harsher than any benefit that they could gleam out of breaking the law then they simply won't do it. Violent offenders do not rationalize in this manner. They are more

The airline company operates as ‘value carrier’ while it has signed number of agreements air line companies of other countries such as Aer Arann, Air Bus etc in order to manage its low cost services. Primary market for Aer Lingus includes Republic of Ireland, continental Europe, UK and USA. In the year 2012, the Irish airline company has carried more than 9.6 million passengers across the boundaries. In the year ended 31 December 2012, the company has reported annual revenue of more than â‚ ¬1,350 million with operating profit hovering over â‚ ¬65 million. The company has established its base airport in Belfast City and shown the interest to expand its destination routes by 2 times in next couple of years (Competition Commission, 2013). The Irish airline carrier has established its base in Belfast City along destination points include Manchester, Birmingham, Gatwick and Heathrow airports of UK ( Competition Commission, 2013). Great Britain-Ireland destination root contributes 30% to 33% of the top line growth and 45% of total passengers for Air Lingus.

[Astronomy subject] Assignment Example | Topics and Well Written Essays - 750 words

[Astronomy subject] - Assignment Example This became an important law in astronomy as it helps determine the mass of any astronomical object. This formula is used to calculate the mass of all astronomical objects including the stars, sun and planets. 2. Describe the relationship between the distance from the Sun and a planets surface temperature. Why does this relationship exist? Explain the following exceptions to the overall trend: Venus is farther away from the Sun than Mercury, yet has a higher surface temperature. Neptune has the same cloud-top temperature as Uranus, even though Neptune is ~10 AU farther away from the Sun. Though the temperature of the planet is affected by its placement in terms of distance from the sun, there is another major factor influencing the temperature. It is the atmosphere of the planet which affects the temperature condition along with distance from the sun. Atmosphere acts as a blanket to retain the heat (Bennett et al, 2009). Mercury, though very close to the sun, cannot retain the heat as the atmosphere or the blanket is missing there. Comparatively, Venus is located farther away from the sun than Mercury, but still the temperature is high which is again because of the thick atmosphere which prevents reverting of sun’s energy back to space. 3. One would use the column titled "Rotation Period" to find out which planet has the shortest days. Are there notable differences in the length of a day for the different types of planets (terrestrial versus gaseous)? Would you have predicted there to be huge differences? Mercury has a long rotation period because of its synchronization with its orbital period; Pluto is synchronized with its largest moon Charon. Venus has a retrograde (clockwise vs counterclockwise) rotation. Eliminate these two planets and a dwarf planet, and what do you find? See the chart at the right to help you answer this question. A day is the time taken for the planet to

Follow the details Essay Example | Topics and Well Written Essays - 500 words

Follow the details - Essay Example Like many photographs, this one is one in which my entire family is gathered about the time when I was celebrating my 10th birthday. One of the reasons that the photograph bears so much importance to me is that it has both sets of my grandparents as well as my mother and father in it. Only a few years after the photo was taken, three of my four grandparents had passed away. In this way, the photo itself is a way to remember the happiest memories of my childhood. The second object is one that I have brought with me in my travels abroad; a leather bound copy of the Holy Koran. The book belonged to my father and my grandfather before him. It was always something that was unique and holy within our household and I remember being fascinated by it since I was very young. This fascination was due in part to the fact that it was physically different than all other books that we had in our house. The leather engraving on the cover and on the back was exquisite and the Arabic calligraphy that covered it had always sparked my imagination. In this way, when my father learned that I would be going overseas to study, he entrusted me with this family treasure. This was done not as a way to keep me safe or as a good luck charm but to remind me of my culture and of the importance of my upbringing even though I would be far away in the land of different customs and interpretations of right and wrong. This type of moral compass and guiding principle of my fai th and of my ethnicity was and is something that I keep close to my heart and treasure to this very day. The final article that this brief essay will discuss is that of my high school graduation diploma. Although having a high school graduation diploma in and of itself signifies little within the current era, it is not the receipt of the diploma itself that is of the most importance. Rather, it is the strong memories that are associated with it, the friendships I made, the times I spent, and the

Answer 3 required and 3 of the optional questions from the uploaded Research Paper

Answer 3 required and 3 of the optional questions from the uploaded information - Research Paper Example These financial statements are to be prepared using a predefined set of standards and guidelines, widely known as the Generally Accepted Accounting Principles (GAAP) (Types of Accounting, 2013). Managerial accounting is an accounting process that reportedly produces information for the sole us of management of the organization. The form and the details to be included in the reportorial information would depend on the intricate and extensive requirements and purpose of management. It was actually disclosed that the information could be more detailed, as compared to financial accounting statements which were identified to be prepared exclusively for external uses. Thus, management could require budgets, forecasts, and financial highlights that would be used to make decisions regarding strategies and plans that would achieve identified goals. Cost accounting was noted to be a branch of managerial that focuses on monitoring and controlling costs. Tax accounting, on the other hand, as the term implies, focuses on accounting facets which are tax-related and are reportedly governed by tax rules and regulations, as well as observance to the GAAP. Governmental accounting, or also known as public accounting (or even fund accounting) was noted to be a type of accounting process and information system that is used by government agencies or public organizations. The main disparity of this type of accounting with private organizations’ accounting system is that their funds are governed by budgets set by the federal government. Likewise, the disbursement of funds are to be allocated subject to the aims or goals of the government agency. Internal auditing accounting focuses on an ongoing appraisal of the financial condition of the organization subject to conformity to accounting standards and accounting laws. Finally, international accounting is the type of accounting process or information system governed by international accounting standards, as contrasted with GAAP. 2. Describe the purposes of financial statements and corporate annual reports. The purposes of financial statements and corporate annual reports include the provision of accurate financial information to various users to serve various needs (Purpose of Financial Statements, 2013). For instance, financials statements are mandated to be published to the public to give them a general overview of the organization and provide information regarding the potential effects of the organization to the local community or to the economy, as a whole. Likewise, financial statements and annual reports are needed by management for decision-making purposes. The companies’ shareholders, on the other hand, use these financial information to determine returns on their investments and any potential risks from currently disclosed external or internal factors that impinge on the organizations’ operations. Concurrently, the investors of the organization need to be given accurate information on the financial condition and status through financial statements and corporate annual reports that contain profits, returns on investment, risks, and market value, as needed. In addition to these various users, financial statements are needed by other financial institutions, such as banks or lending institutions when organizations apply for loans or financial assistance in various endeavors. Suppliers also need the information disclosed in financial stateme

Discussion 12 nur 703 Assignment Example | Topics and Well Written Essays - 250 words

Discussion 12 nur 703 - Assignment Example Reduced activities and change in work location due to closure are other possible role conflicts. APRN might gain support for the evaluation by seeking advocacy roles of special interest groups and incorporating evidence based information on its evaluation for authenticity. The county government, the community whose members seek care services, nurse advocacy groups, human rights associations, the facility’s personnel, and civil rights activists are some of the stakeholders and their involvement will be through seeking and incorporating their opinions on significance of the facility and possibility of closure (Milstead, 2013). Five hundred dollars is a potential budget for the evaluation that will rely on local stakeholders for data. Communication and travelling allowances for members of the evaluation team will be the main expenses. A survey design, with interviews and focus group discussion as the data collection techniques and random sampling, will be the research methodology. Possible conflict of interest, need for anonymity, beneficence, and non-malfeasance are some of the potential ethical consideration (Schneider, Whitehead, LoBiondo-Wood, & Haber, 2012). A written report will be delivered to the county government that may publish it to the public at discretion. I have been faced with a similar advocacy issue regarding workers’ rights in a facility. The issue was about possible change in management theory and incorporating stakeholders, including the management, in evaluation led to positive outcome. The facility changed its management approach and empowered its

Company Introduction, Market Segmentation, and Product Positioning Essay

Company Introduction, Market Segmentation, and Product Positioning - Essay Example However, today, it has expanded to immeasurable lengths. For a young company that is barely ten years old, the financial performance is excellent. It had opened three other branches in other states including Ohio, Michigan and Massachusetts. However, the company has also opened a branch in Australia which is thriving like its mother company. The company distinguishes itself as fast fashion trademark and offers high fashion clothing to reach the public at affordable prices. The Company’s mission statement is ‘when the customer looks good, we look good.’ In light of this, the main aim of the company is to ensure their customers look trendy and thus keep up with fashion (London Business School, 2008). Trendy Fashionista has over 500 employees in all their five branches. Additionally, it boasts of a wide range of customers from all backgrounds. The clothes sold are not the average clothes found in cloth stores. The company’s fashion designers go an extra mile t o make clothes that are unique. This coupled with the fact that the company sells its clothes at fairly cheap prices makes Trendy Fashionista the perfect destination for a fashion conscious individual. Marketing Plan Introduction The fashion industry is ever changing due to contribution of companies like Topshop, H&M and Zara (Helm, 2008).

At the moment, once the fashion designers finish their job, the company has to outsource manufacturers. Therefore, the company needs to start making its own clothes. Furthermore, the company intends to increase its distribution and possibly open one more store in Australia. This will take care of the growing clientele base in Australia. Finally, the company intends to start taking part in community development. The founders are passionate about developing the community and thus the target is to set aside $10,000 to be donated to various Non Governmental Organizations.

Business goverance Essay Example | Topics and Well Written Essays - 1250 words - 1

Business goverance - Essay Example The BLM wants to charge the DBD $3 million in case the DBD does not reclaim the land when it has done drilling. In this case, a problem between the two arises. In understanding the situation at hand, we must look carefully at what a principal – agent problem is. The principal – agent problem occurs when a situation arises that motivates an agent to represent the principal in dealing with a particular situation. The BLM may be unable to meet the cost of drilling or may be too involve to drill the oil (Winch 2010, 28). This makes them delegate the whole drilling to another company. DBD, on the other hand, may be specialized in the drilling of oil and they may be the best person who can drill this. In leasing the land by BLM to DBD the company stands to gain more than it can lose as the cost of drilling and maintenance will be passed on to DBD. Nevertheless, a problem arises where they are not sure whether DBD will reclaim the land after it is done with drilling or not. It, therefore, wants to charge DBD $3 million as money for reclaiming the land which if they do not they will spend $3 million to do it whereas DBD will spend $2 million for the reclamation of the land. The total cost of leasing the land to DBD is $5 million so they are afraid if they do not charge the $3 million, they would only make a profit of $2 million shillings. This is a business and its principle objective is to make maximum profits. In principal – agent delegation many advantages are drawn. These include improved decision-making and the efficiency of these decisions. Decisions are wholly passed to the agent who takes the problems as their own and works to towards finding viable decisions. This means that the principal only wants a particular payoff but the rest is left to the agent. In the example of BLM and DBD, the BLM can be likened to a Landlord and the DBD as a tenant. The property owner will lease the land to the tenant and pass all that concerns to it to the tenant

It can have short and medium term effects. The terrorist groups are used to collect funds from criminal enterprises, unregulated banking system and also through a network of charitable organizations. Some states are involved in funding the terrorist groups indirectly. They provide logistics as well as financial support to those groups. They position their finances in such a fashion that one cannot find unlawful activities and appears to be legitimate spending. The terrorist groups use multiple methods of fund transfer which makes it difficult to distinguish between legitimate and illegitimate transfer. An array of criminal activities also serves the purpose of funding for the groups. A significant portion of remittance from drug trafficking is generated only for the purpose of transferring the amounts to fund the terrorist activities. The operation of the terrorist activities within the globalized era is striking. For about a decade now, terrorism has become
