Friedrich Froebels Ideas On the Role of Play In the Early Years Education Essay Example for Free

Friedrich Froebels Ideas On the Role of Play In the Early Years Education Essay Play is probably the very first thing that comes to our minds when we start thinking about our childhood. Certainly its hard to talk about early years without referring to play, as it is a part of childrens natural behaviour, embedded in their spontaneous day-to-day life. The fact that the play is enjoyable is generally agreed, but the value of play in school, however, has been in the centre of much debate in the past (and it seems like that debate is still going on today). The roots of contemporary understanding of the role of play in early childhood education extend clearly to Friedrich Froebel, a German educator, who organized and systematized the methods of early childhood in accordance with the idea of the spontaneous, self-sustaining nature of children (E. Evans, 1971, p. 43). Froebel believed that every child had within him all he was to be at birth, and that the proper educational environment was to encourage the child to grow and develop in the most favourable manner. Young children are to be regarded and tended essentially like plants. Like these, if they were given the right conditions, they would grow and unfold and flower, by their own law, each according to its individual capacity and destiny. (E. Lawrence, 1969, p. 195) In his study of child-nature one of the most marked characteristics, which attracted Froebels attention, was the childs inborn desire for activity, which reveals itself in play. According to Froebel, play is the freest active manifestation of the childs inner self which springs from the need of that inner living consciousness to realize itself outwardly. (H. Bowen, 1907, p. 116) Froebel made a significant contribution to early childhood education by seeing play as a process in which children bring to realization their inner nature. He recognized that children began to learn as soon as they began to interact with the world, and he reasoned that since the interaction was mostly in the form of play, the way to educate a child was through play, as a means of awakening and developing the active and presentative side of his nature; wherefore none, not even the simplest gifts from a child, should ever be suffered to be neglected. (F. Froebel, 1901, p. 77) Froebels continuous studies of the function of play in a childs life came to fruition in the concept of the Kindergarten ? a place where children instruct and educate themselves and where they develop and integrate all their abilities through play. Froebel believed that play provided the means for a childs intellectual, social, emotional and physical development. Games were not just idle time wasting, but the most important steps in the childs development, and they were to be watched by teachers as clues to how the child is developing. It is through play that the child learns the use of his limbs, of all his bodily organs, and with this use gains health and strength. Through play he comes to know the external world, the physical qualities of the objects which surround him, their motions, action, and reaction upon each other, and the relation of these phenomena to himself, ? a knowledge that forms the basis of that which will be his permanent stock for life. (H. Bowen, 1907, p. 101) However, Froebel didnt think that the play of young children should be unprompted at all times. For him the skill of adults was in knowing how and when to intervene, how to support and extend childrens play to help them to grasp and to try out their learning in concrete ways. (T. Bruce, 1997, p. 23) To stimulate learning through well-directed play Froebel designed a series of instructional materials, which he called gifts and occupations.

Is Halls Encoding Decoding Model Still Useful Media Essay

Is Halls Encoding Decoding Model Still Useful Media Essay Encoding and Decoding in the Television Discourse was written by Stuart Hall in 1974, which was critically acclaimed in mass communications research and paved the way for many academics to build upon the theoretical model of encoding and decoding between audience and receiver. Messages are sent and received between the audience and the receiver, but the meaning of the text is dependent on the audiences cultural background, to accept, reject or negotiate the text with a margin of understanding, (Hall: 1974). This analysis of the model of research will examine the usefulness of Halls theory on contemporary mass communications research, and will follow the next generations of audience research and the application of the model in current media today. Firstly it is necessary to recognise that the encoding decoding model has much older theoretical roots. One of the main theoretical roots of the model (critical theory) referred to the post 1933 emigration of scholars from the Marxist school of applied Social Research in Frankfurt to the United States (Mcquail: 2000). The school was established to understand the failures of Marxism, and Stuart Halls essay examined the mass media as central to the culture of capitalism with meaningful discourse, this is relevant to the success of the model which appears critically popular in looking at capitalism with a predominant media. Secondly the theory readdressed the themes of the Use and Gratifications theory examining audience power over the media rather then mediated effects on the audience (Katz: 1959). The theoretical study later concluded that audiences use the media to fulfil there own needs and gratifications (Katz, E., Blumler, J. G., Gurevitch, M.: 1974). Halls theory represents a similar model with elegant simplicity, to make it a key text, (Mcquail: 2002). Importantly Halls model focuses on groups rather then the individual which is more useful for looking at mass communications dominance due to social class and cultural heritage. Both the political and theoretical foundations of the model have implications on its relevance today as its usefulness is paramount to a mass media dominated society and the driving relationship between audience and media. The model itself described by Hall is, The institution -societal relations of production must pass into and through modes of language for its products to be realised. This initiates a further differentiated moment, in which the formal rules of discourse and language operate. Before this message can have an effect it must first be meaningfully decoded. It is the set of decoded meaning which have an effect, influence entertain, instruct or persuade with complex perceptual cognitive, ideological or behavioural consequences (Hall, 1974: 3). Hall (1974) suggests four decoded meanings from this model, the dominant code of preferred meanings, the professional code transmitting a message signified within in a hegemonic manner, the negotiated code of adapted and oppositional elements and the oppositional code, clear understanding but with a connotative inflection and rejection for audience, (Mcqual: 2002). This segregation of groups was tested by David Morleys The Nationwide Audience in 1980 which complimented Halls research but importantly gave birth to second generation ethnographic research. This was praised by Morley (1992) where he described how Halls model gave rise to decode media messages and sparked emphasis toward a new phase of qualitative audience research, gender realities and media consumption. Ethnographic research predominant in the 80s examined how television was a social resource in family dynamics and the relation of media in everyday life, rather then decoding one programme through a single medium. Fish wrote that one studies the every day life of a group, and relates the use of (a reception of) a programme or a medium to it (1979: 329). This quality of research transcends further into areas such as gender and communities in which Halls model can not disseminate. Third generation audience research offers a constructionist analysis of contemporary media in the sense of how we are aware and conceive our roles with the audience and reflexivity of our understanding of ourselves as the audience. Radway (1998) emphasized the audience point of departure subjected to television and our self reflection of the media and our knowledgeable participation is where audience research lies. Essentially second and third generation research explored more deeply into social constructivism, which compliments audience media relationships. Although Hall was praised by Nightingale (1996) for the model researched media linguistics and social semiotics to combine research methods and genre in new ways. The audience understanding of linguistics and there self representation through genre is a critical area of contemporary audience research. After the third generation of audience research, Schroder (1994) described the turn towards ethnography and the everyday, as a threat to write the media as the focus of research out of existence. Political research addressed later, will demonstrate this to be untrue and encoding/decoding remains useful in social and cultural class on a broad scale. Nightingale (1996) criticized the model for the assumption that only dominant culture is produced through television and the modernity of the model should recognise the cultural hegemony distributed through society. Fiske (1997) described, the characterization of the television text as a site of a struggle between dominant ideologies working to produce a closed text by closing off the opportunities it offers to resistive readings, and the diversity of audiences who, if they are to make the text popular, are constantly working to open it up to their readings. Audience participation has increased dramatically in contemporary television, addressing the dominant reading and offering opportunities for varied outcomes. The rising popularity of reality TV shows is a good example of a larger audience participation, which will be addressed later on. Before looking at the changing media landscape and the issues that affect the use of the decoding model in the close present. It is first necessary to pay attention to David Morley. In The Study of the Nationwide Audience, Morley (1980) described members of a given sub-culture tend to share a cultural orientation towards decoding messages in certain ways, similarly Hall (1981b) described individual readings of messages will be framed by shared cultural formations and practices (p.51). This study used Stuart Halls encoding model and successfully identified dominant, negotiated and oppositional readings based on cultural background. The limitations of this were later noted by David Morley (1992) in his critical postscript in Television Audiences and Cultural Studies where he acknowledged his terms of class (middle and lower) are descriptive labels that do not divulge the detailed ethnography of the people studied. He also describes The Nationwide Audience as scratching the surface of c ultural practises that could range from religion to biology. Therefore we can acknowledge that the model lacks the detail desired to penetrate the cultural depth of the audience, but the model can disseminate by social and cultural class on a broad scale. The Nationwide Audience was defined in relation to texts rather then mediums (Holmes: 2005) but audience medium interaction was also examined in Morleys postscript. Critically the audience medium changes the way the audience receives the text. The internet has been the largest rising social medium in contemporary technology and is very different from television. Television is considered to be an acoustic medium like radio, in which sound represents the privately experienced equivalent of a social world characterized from all directions ( Holmes: 2005, p.114). The Internet presents a world of information, a virtual reality linked with broadcast networks, interactive communication, and a definitive need for the audience to participate. The internet and online broadcasting were not present at the time of the original study forming an argument that Halls model is outdated as it does not account for changing mediums and New Media content consumed by the audience. New genre has allowed reflection on old mediums acquainted to their ontological power (Holmes: 2005). An example is the spectacular increase in active audience participation in reality TV, founded on a principle of imaginary substitution; and audiences viewing a representation of themselves. Using Nightingales assumption that the model assumes only dominant culture is produced through television; reality TV rebuffs a dominant understanding through the audience participation. Critically as Halls model arguably only accounts for a dominant ideology, it has extremely limited use in looking at audience participation and influence. The ITVs X factor audience has an estimated 10 million viewers, and there are various reality TV voting shows such as big brother, that arent just primetime TV, but can dominate the front page of many tabloid magazines reaching a predominantly larger circulation of people then television. Third generation audience research best describes the audience participation, in there active role in the media in determining the outcome of the represented. Social constructivism defines reality TV, and a dominant hegemony is arguable defeated. Halls model integrates determination and freedom via the producer and consumer, but arguably disappoints in its linearity. Murdock (1989) criticizes the models overemphasis of the rational dimension of the response. Comparing the basic nature of the model to Lasswells comment (known as the Lasswell model) Who (says) What (to) Whom (in) What Channel (with) What Effect recited before Hall, accounts for the medium and the effects within research, justifiably explaining the linear nature of the encoding mode in comparison. Modern communication research needs further consideration of the medium. Although Lasswells model can be seen as a transmission of communication as opposed to mass communication it is arguably more useful then that of Halls in allowing for current new media interactivity and the medium. Murdocks description of the overemphasis of unilateral response is justifiably irrelevant in large groups, in which it is useful to examine mass communication from a political perspecti ve. We previously mentioned Halls model can penetrate social and cultural class on a broad scale and mediated politics can theoretically be applied to the encoding model. The conservative government will have most support from the upper social class; typically bankers and businesses that support the privatization and socio-economic freedom of the individual agreeing with the dominant message delivered through the media. This message would understandably be rejected be trade unionists and the lower class that live in less privileged economic conditions. The middle classs are the negotiable reading, and are essentially the battleground for government votes. Thatcherism and the conservatives long stint in power from 1979- 1996 can be examined in relation to encoding and decoding the mass audience, similarly to Tony Blairs acknowledgement of the model in Labours reign from 1997-2010. During Margaret Thatchers reign the traditionalist capitalist ideology, family values and patriotism presented through the media were a success in cultural hegemony. It can be argued that Thatcherism was successful due to its ability to address the concerns of ordinary people through its articulation of right wing politics The study of this is described by Gauntlett (2000) who says In studying the media and gender, one could use this approach to see how the media might make certain formulations of masculinity, femininity and sexuality to be natural, inevitable and sexy (p.30), Certainly Margaret Thatchers formulation of ideology expressed certain values onto the British public that permeated their culture. Recapping on the value of Halls model in mass communication as a meaningful discourse in capitalist culture, the application to politics and the media is evidence of its use. Hall (1996) also argues Thatcherism successfully maintained support of the working class through popular authoritarianism. It can be seen the British people submitted to the psychological message of the driving capitalist machine and arbitrary nature of political power. The Falklands War is a great example of how the hegemonic embodied populism to remain in power. The ability to be able to look back and examine governmental power, political strategy and articulation of the people is vitally important for understanding the nature of our media, culture and public and can be used by government and historians to shape future policies and projections. A large amount of credit must go to Halls model that can textualize and open up the coding used between audience and public and represents an important academic angle f rom which to do so. Although Stuart Halls model is based around theories of mass communication, Dicks (2000) applied Halls encoding/decoding model to a local heritage museum based in South Wales with the understanding that heritage and the museum visitors can be studied as a form of social communication. Heritage is examined as a cultural communicative practise, linked to the vernacular aesthetic of the people. The social model of communication looks at the practises of production and consumption in relation to politics, economics and culture, (drawn from the framework of Stuart Hall). Initially the heritage site, (which was being built in the early 90s) dedicated to the miners strikes felt the Conservative government had projected a Disney model of narration to the heritage site that didnt reflect the community feel, thus as local historian was able to get involved in the development process, outlining the encoding element. When the public visited the museum they were asked a series of questions before , and after there interactivity with the museum. Generalising the findings presents Hallss theory in accurate modern context of dominant, oppositional and negotiated responses to the decoding of the information presented due to economic and cultural heritage. However they should not be simplified into this manner as the detail of the answers given, present a larger scope of negotiation from the public, due to the museum not actually presenting a dominant hegemonic view of the miners strikes. In this sense, the question is how did the visitors negotiate with the negotiation? Essentially using there own social-cultural class to deconstruct the narrative. Concluding the findings of the article, the encoding aspect of the museum content presented a clear divide between the government and local idea of the aesthetic and values of the museum, and decoding is representative of cultural and economic means but does not necessarily descend from hegemonic measures passing scope for more negoti ation. The article has clearly used the model to an intelligently critical viewpoint of an audience subject to heritage with large significance thus cementing its usefulness in this element of modern society. If the model can be used to deconstruct our perseverance of heritage and reveal political and cultural means of the audience, it has another credible use. Importantly the model was able to be adapted to reflect more audience freedom and negotiation reflected in contemporary audience theory today. It is now necessary to revisit many aspects of Halls model, tying in the theoretical, alongside politics, the changing media landscape and the wider scope of knowledge. Firstly, taking a political stance, the continuities between Thatcherism and New Labours political projection were documented by Hall (1998), as the authoritarian populism of Britain was echoed in the New Labour rhetoric under Tony Blair. As we previously covered the theoretical roots of the encoding model stem from emigration of scholars from the Marxist school of applied Social Research, and Labour learnt a lot with its affiliation with Marxism. Tony Blairs contribution to the magazine almost certainly contributed to his understanding of how to modernise his party and use the media effectively as a dominant mass communication tool. Where the Use and Gratifications model failed in Marxist academia, Halls model successfully justifies mass media dominance. If we revisit the third generation audience research we can see a link between the constructionist viewpoint and the findings from the heritage museum. Participants in the heritage museum research were able to self identify there role in the research and offer a more negotiated viewpoint, as such there is greater audience understanding of there identity in shaping the outcome, and the ability to use the encoding model with more modern research giving it greater use. Referring back to Nightingales criticism of the model, that it assumed only dominant culture is produced through television. The heritage site had no dominant message and yet the model was able to be used to negotiate readings and audience understanding. The model was able to do this because it still posed relevant for disseminating social and cultural class but its real findings and the examination of further audience negotiation compliments its ability to embrace the audience understanding of third generation research. Whilst it was concluded modern television such as reality TV produced flaws in Halls model, one would assume there would be new documented research on the progression of New Media and the distribution of programmes through changing mediums and a diverse virtual world of information. There is not such a wealth of information out there which asks larger questions as to whether the encoding/decoding model has been cast aside with changing media dynamics. One of the most important recent media developments is the rise of social media. One of largest and most predominant media campaigns in western politics was Barack Obamas presidential campaign in 2008. Meerman Scott (2007) believes this was won due to Obama being the candidate that mostly strongly embraced social media. The encoding model does fall short of being able to connect to interactive media, user generated content and networking that is not subject to a mass dominated message, but instead the articulation and communication of m any individuals independent of thought. Obama didnt pursue an authoritarian message with his campaign to be mediated across the web, but many individuals wrote multiples blogs raising awareness online. This has given me the viewpoint that mediated liberalism and the freedom of audience control has rapidly increased due to social media. Halls model is relevant in predominant media, it will not transcend into the online social forum. Similarly the role that the audience plays online is very much what people do with the media, (echoing the Use and Gratification model) and attempts to cast aside dominant ideology or reading. Social Media is technically the most recent revolutionary form of media in which the encoding model appears to fall short in its application of audience understanding. It can however be concluded that there is very little academic research on this topic thus far to determine the model in this form. Conclusively, Stuart Halls model has taught me, in regards to politics and the media, it is best applied in context of the media dominance of society and has clear use and purpose in analysing recent UK governments and can contextualise the relationship we have with the autonomous power above us. The model has limited use in modern television such as reality TV and the changing media landscape, and falls short of the social media revolution and the powerful nature of the audience online. The model itself though, does transcend the ethnography and constructionist nature of the research that followed the model, and its ability to be applied to a local heritage site and successful disseminate an audience, proves it can still be useful in modern society. Similarly the social and cultural decodings of the model in mass audience research have been justified and complimented by various researches undertaken.

Implementation Of The Library Management System Technology Essay

Implementation Of The Library Management System Technology Essay This report focuses on the design and implementation of the library management system. It deals with the complete processes on building and implementing it. It focuses in the technical aspects of the system starting with identifying the necessary components and building the relevant relationship between or among them as needed for the smooth and efficient operation of the system. The process starts with the entities involved in the system, with proceeding towards the ER Diagram in order to identify the meaningful relationship between the entities. Next is the table design which fulfils the normalization principle of relational database system and finally the physical tables are created with the necessary and relevant data in them. The system can keep track of the members joining and leaving the library, borrowing and returning of the books. Checking the availability of the books using different attributes as parameters. Finally checking of the overdue books and fines payable is another feature of the system. Abbreviation SQL Structured Query Language ER Entity Relationship ERD Entity Relationship Diagram DDL Data Definition Language DML Data Manipulation Language 1. Introduction: Library management system is a system that facilitates the easiness in using and tracking the library assets. It provides an instant real picture and process of all the activities that happens in a library commencing from the member joining the library and the same leaving the library with all the utilization and rendering of the library facilities in between. 1.1 Background: A library is a collection resources especially books that a wide range of individuals can access and share them. Library has been in use since 15th century as has been gone through several stages of improvisation and its been in the form as today. Library can be categorized into different types according to the organization that runs it as Academic library, public library, School library etc. Further more it can be classified according to the subject matter of the documents it contains as Medical library, Law library, Arts Library etc. Libraries are organized in a way to access the materials in an easy an effective way. There are several systems in practice which makes the library organized. Library is basically concerned about acquisition, preservation and administration of its resources. In order to carry out these tasks a system is implemented. All these process has been carried out manually before the advancement of new technologies. Now the computer automated system is in practi ce to carry out these systems which makes all these processes effective and efficient. These computer automated systems makes easy for the members to access the available resources where as it makes easy for the librarians to keep track and maintain the library resources. 1.2 Objective: The objective of the entire project Design and implement a library database. Construct the expandable search alternatives for the best handling of member queries, searching the books by book title, book author, ISBN. Construct the search option for the librarian to find the over due books and fine details. 1.3 Scope: The goal of this project is to design a database for a college library which will be implemented in the form of an online library which provides members a digitized catalog in order to search the books and browse information about the book. In the same time this system also enables the librarians to find the information of the book in a precise way especially the fine and overdue books. The summarized activities are as follows: Members registration Book issue and collection Book cataloging Collecting overdue book and fines 1.4 Technology Used: Technology used in this project is MYSQL. 2. Current system and its fallacy The library is managed, organized and run by the librarian. All the functions like managing books, issuing books, and finding the books for the members is carried out by librarian. This is where the time and effort is consumed. Whereas the members also find difficulty in finding availability the books and need the assistance of librarian in every step. The librarian also finds it tedious if s/he has to deal with several members at a same time. There is a difficult system 2.1 New system and its features The new system is also based on the daily routines of the library but the function carried out within it will be automated. Once all the data are stored in a database with a proper system both the librarian and members will be benefited over the traditional system as it is designed with the following features in mind: Effective The library system will streamline the library process which accelerates the effectiveness of the library. Efficacious The users are served in a reasonable time and are also able to search and select their required books. Efficient Members and Librarians are able to use the system quickly without any long procedures. Elegant Since the system is intuitive and comprehensive and is designed to be as effortless as possible 3. Literature Review This report focuses on the conceptual design of the system using ER i.e. entity relation ship diagram which is a diagrammatic representation of the entities and their relation with one another which is explained in the forth coming section. The ER is constructed using the UML. UML stands for unified modeling language. Software engineering uses UML as the standardized modeling language. It was created by Object management group. UML is a language used to present the blueprint of the system to be designed. It has got its own notations to represent the processes and objects involved in the software to be designed. ER Diagram is a graphical representation of the entities and relation between them in order to execute a system. This Diagram is constructed in some available ER Diagramming packages which is Visual paradigm community edition in this case. MYSQL has been chosen as the database system for this library management system. Since it is relational database available under the terms of GNU public license. Besides the ease of using through a variety of freely available tools as PHPMYADMIN makes a choice of most of database designers today. Besides it is the database of choice because of its high performance, high reliability and ease of use. Moreover it runs on maximum operating systems available in the IT fraternity like windows, Mac OS, Linux, Solaris, IBM . 3.1 Requirement Analysis The library management system should be able to fulfill the user requirements to all the extent and when analyzed are found as follows Member should be able to join and leave the library Member of a library should be able to borrow and return books Member of the library should be able to check book availability. Librarian should be able to check the overdue book and the fines payable. 4. New system Design The library management system with the goal to cover the requirements noted above needs to be developed in a system which has the proven track of implementing the same or same type of systems. So, a relational database system is chosen to carry out the task. The relational database system is basically a system where data is stored in a container called tables and the relational among them is also stored in the same form. The new system follows the waterfall model of the software development models. The processes in execution order in a water fall model are: Requirement analysis Software Design Integration Testing Deployment Maintenance 4.1 Conceptual Data Model The design of this data model is part of software design phase. After going through the requirement analysis the next step is the Software design and in it conceptual data model is the first among them. The conceptual data model identifies the necessary entities and establishes a relevant relation among them. In this design ER Diagram (Entity relationship diagram) is created to illustrate the relations between the entities. The diagrammatic conceptual representation of structured data is known as ER Diagram. Relational schema is used in this method for database modeling. The dominant method of database designing in the Software industry is the ER Diagram. Peter Chen invented the ER diagram in the early days to model the design of the databases from a more abstract perspective particularly for the academic research. Based on that, ER diagram was further elaborated and now is used worldwide in different forms. ER diagram deals with three major components of a database namely, Entity, A ttributes and Relation. Entity is nothing but a set of particular thing which shares common properties. Whereas attributes are the set of common properties which the entity share. The last but not the least component of an ER Diagram is a relation which is the model of association between one or more entities. Each relationship in ER Diagram has a cardinality which defines the degree of relationship between the two entities. In other words how the related entities has presence over one another. Cardinality is of three types: one to one, one to many and many to many. In an ER diagram the one occurrence of the entity is shown by a vertical line and many occurrence of the entity is shown by the crow foot. The relationship is established on the basis of several keys called primary keys and foreign keys. Besides there are other keys called candidate key and composite key. Primary key: The attribute which uniquely identifies a record in a table is called primary key. Foreign Key: As the name specifies this is the key which points the primary key of another table to which it is related. Candidate Key: The attribute that is identified to be unique for a given record is the candidate key. Composite Key: Primary key consisting of more than one attributes to identify the record uniquely is composite key. For the library system the constructed ER Diagram is shown below. 4.2 Logical Design The logical representation of the entities is drawn out in the logical design. It is a table prototype of the entities. Based on the conceptual Design above we do have following table and entities mapping. Member member_id (integer), member_fname (varchar), member_lname (varchar), member_address(integer), member_phone (varchar), member_email (varchar), member_type(integer) member_id is primary key and member_address and member_type are foreign keys to build the one to many relationship between address table and member table and member table and member_type table respectively. Member_Type member_type_id(integer), member_type_name (varchar), member_type_allowed_day (integer), member_type_fine (integer) member_type_id is primary key. Address address_id(integer), address_description (varchar), postcode (varchar) address_id is primary key. Postcode postcode_id (integer), postcode_description (varchar), postcode id is primary key. Books ISBN (integer), book_name (varchar), book_status (varchar), book_type_id (integer), book_publisher(integer) ISBNis primary key, book_type_id, book_publisher are the foreign keys which relates the the book table with book type with one to many, and with publisher table in one to many relation ship as well. Book_Type book_type_id(integer), book_type_name (varchar) book_type_idis primary key. Publisher publisher_id (integer), publisher_name (varchar) publisher_idis primary key. Author author_id(integer), author_fname (varchar), author_lname (varchar), author_email (varchar) author_idis primary key. Librarian librarian_id(integer), librarian _fname (varchar), librarian _lname (varchar), librarian _address(integer), librarian_phone (varchar), librarian_email (varchar) librarian idis primary key, librarian_address is the foreign key which establishes the one to many relationship with address table. Book_Author ISBN(integer), author_id(integer) ISBN is the foreign key which maintains one to many relation with books table and author_id is the foreign key which establishes the one to many relationship with author table. Thus in this way Many to Many relationship is established between Book and Author table. Borrow borrow_id(integer), member_id(integer), ISBN(integer), librarian_id(integer), borrow_date (date), return_date (date), expected_return_date (date) borrow_id is the primary key and memer_id, ISBN, librarian_id are the foreign keys. Member table and borrow table shares one to many relationship, Books table and borrow table shares one to many relationship and librarian table also shares one to many relation with borrow table involving the mentioned foreign keys. In other words many to many relation ship occurs between these entities i.e. many to many between librarian and books, member and books. Fine fine_id(integer), borrow_id(integer), librarian_id(integer), fine_amount (float), fine_id is the primary key and borrow_id, librarian_id are the foreign keys. Fine is associated with borrow in one to one relation whereas librarian is associated in one to many relation. 4.3 Normalization After the conceptual model the logical representation of entities are created and then before converting them into the tables with physical existence normalization is carried out. Normalization is process by which the data redundancy is nullified. This is achieved by disintegrating the single relationship with ambiguity into multiple smaller and precise relations. The tables holding such data are split into several atomic tables so that they become isolated and the data manipulations are carried out in a propagative way i.e. a change in an entry point data in a relation makes it triggered and reflected throughout the relations which frees tables from modification anomalies, i.e. insertion, updation and deletion anomalies. Several levels of normalization exist in database design and are called Normal Forms. They are First Normal Form (1NF), Second Normal Form (2NF) and Third Normal form (3NF). First Normal Form (1NF) First Normal form is concerned with multiple valued attributes. For the table to be in a first normal form it cannot contain multiple values for any attributes. Second Normal Form (2NF) For the table to be in second normal form the non key attributes of the table shouldnt be partial dependent on any single element of composite primary key. Third Normal Form (3NF) For the table to be in third normal form the non key attributes shouldnt have the transitive dependency on the primary key. The tables for the different entities are normalized in following manner: Books Table (without normalization): Fields (ISBN, book_name, book_status, book_edition, book_type, book_publisher, book_author) where ISBN is the primary key. books table before normalization In the above table the author value is repeated in the book_author table, for the table to be in 1NF, the table cell must contain a single value. The next is the value of book publisher and book type is repeated in multiple rows so it results in the update, insert and delete anomalies. To overcome this problem the author name and publisher entity are separated into multiple tables as shown below. The author table is created with author_id as primary key. Author Table: Fields (author_id, author_fname, author_lname, author_email) where author_id is the primary key. author_id author_fname author_lname author_email 1001 Max Godwell [emailprotected] 1002 Robin Hood [emailprotected] The relationship between book and author table is maintained in book_author table which is many to many as many a book has many authors and an author can write many books. This relation is established by creating a third table book_author which maps book to author and vice versa. This table contains two fields both as foreign keys which refer to book and author table respectively to establish one to many relationship on both sides. Book_Author Table : ISBN author_id 91238745654 1 91238745654 2 Publisher Table: Fields (publisher_id, publisher_name) publisher_id is the primary key. Similarly the repetition of publisher values in a book table is rectified by creating a publisher table as publisher_id as primary key which is then mapped as foreign key in books table to create one to many relationship, which rectifies the insert, update and delete anomaly thus creates 1NF in all cases. publisher_id publisher_name 1 Apress 2 Princeton Book_Type Table: Fields (book_type_id, book_type_name) book_type_id is the primary key. Similarly the repetition of book type values in a book table is rectified by creating a book_type table with book_type_id as primary key which is then mapped as foreign key in books table to create one to many relationship, which rectifies the insert, update and delete anomaly thus creates 1NF in all cases. Book_type_id Book_type_name 1 Computing 2 Economics The second normal form deals with the dependency of the non key columns with the primary key, i.e. no non key columns can depend upon another non key columns or no non key columns can depends on any one column in case of composite primary key. The conclusion is all the non key columns must be dependent on primary key strictly. Since this is also satisfied in all the tables above all the tables satifies 2NF as well. The third Normal form deals with transitive dependency of non key columns, since this is abolished in all the tables above all the tables are in 3NF as well. Books Table (Normalized): Fields (ISBN, book_name, book_status, book_edition, book_type, book_publisher) ISBN is the primary key, book_type is the foreign key referring to book_type table and book_publisher is the foreign key referring to the publisher table. Books table after normalization Member Table: Fields (member_id, member_fname, member_lname, member_phone, member_email, member_address, member_postcode, member_type, member_allowed_day, member_type_fine) member_id is the primary key. Member table before normalization The table above contains repeated address, repeated postcode, repeated member type, repeated member_type_allowed day and member_type_fine so this should be resolved to convert the tables in 1NF. Since there is no composite primary key there is no partial dependency as such so once the above table is resolved to 1NF it becomes 2NF as well. Since member_type_allowed_day, member_type_fine is dependent on member_type alone which is dependent in member_id it creates transitive dependency. So the table to be in 3NF this anomaly should be removed. Again to overcome these anomalies the tables are separated and the relation between them are established accordingly. The member, address, postcode and member_type tables are separated as below to convert into 3NF. To avoid the repetition of member type in member table the member type is separated in member_type table with member_type_id as primary key and member_type as foreign key in member table which creates one to many relation between these two tables. This also rectifies the transitive dependency existing on the member table formerly and thus resolves the table to 3NF. Member_Type: Fields (member_type_id, member_type_name, member_type_allowed_day, member_type_fine) member_type_id is the primary key. member_type_id member_type_name member_type_allowed_day member_type_fine 1 Student 14 10 2 Lecturer 30 5 The dependency of address in postcode also creates the violation of 2NF through the dependency of non key attribute in another non key attribute other than primary key so this is further resolved by splitting address and postcode table separately. The address table has address_id as primary key which is referred in member table as foreign key which establishes one to many relation between them. At the same moment the postcode table is created with postcode_id as primary key and is referred in address table as foreign key named postcode also creates one to many relation between postcode and address. Thus the 2NF violation in member table is abolished and further more all the resulting table satisfies all the Normal form conditions. Address Table: Fields (address_id, address_description, postcode) address_id is the primary key and postcode is the foreign key referring postcode_id in the postcode table which creates one to many relation between address and postcode table. Address_id address_description postcode 1 121 East Road 1 2 45 Parr Road 2 3 36 Jhon Road 3 4 23 Plashet Road 1 Postcode Table: Fields (postcode_id, postcode_description) postcode_id is the primary key. postcode_id postcode_description 1 E15 3QS 2 NW9 1NF 3 SE1 2NX Member Table (Normalized): Fields (member_id, member_fname, member_lname, member_phone, member_email, member_type, member_address) member_id is the primary key; member_type is the foreign key referring to member_type_id in member table to create one to many relations between these two table. member_address is the foreign key referring to address_id of Address table to establish another one to many relation. As in case of librarian the repeating fields in a table address and which caused the insert, update and delete anomalies so violated 1NF and this is resolved by creating the Librarian table with the foreign key mapped to address table thus maintaining one to many relationship and thus abolishes any Normalization violations and thus results in satisfaction to all the Normal forms. Library Table (without normalization) : Fields ( librarian_id, librarian_fname, librarian_lname, librarian_phone, librarian_email, librarian_address, librarian_postcode) librarian_id is the primary key. Library Table (normalized): Fields (librarian_id, librarian_fname, librarian_lname, librarian_email) librarian_id is the primary key and librarian_address is the foreign key which refers to address_id in the Address table to create one to many relationship. Borrow Table (without normalization) : Fields (borrow_id, member_id, ISBN, issuing_librarian, borrow_date, return_date, expected_return_date, returning_librarian, fine_amount) borrow_id is the primary key. Borrow table before normalization The above table violates the 1NF by repeating the librarian ids at the same once it is resolved all other normal forms conditions are satisfied. The borrow table is divided into one more table as Fine and the librarian is associated to Borrow and Fine table separately through one to many relationships in both cases. This eradicates the violation of normal forms and thus makes the form normalized up to 3NF. Fine table: Fields (fine_id, borrow_id, librarian_id,fine_amount) fine_id is the primary key and borrow_id is the indexed foreign key which is mapped to the borrow_id of the borrow table, so as to create one to one relationship between them. The relation ship is created one to one as one borrow can only have one fine and not more than once. fine_id borrow_id librarian_id fine_amount 1 1 1001 10 2 2 1002 15 Borrow table (Normalized): Fields (borrow_id, member_id, ISBN, librarian_id, borrow_date, return_date, expected_return_date) borrow_id is the primary key. member_id is the foreign key which referrs to the member_id of the member table thus creating one to many relationship in between. Similarly ISBN is the foreign key that refers to the ISBN in the book table thus creating one to many relation between them. Similarly librarian_id is the foreign key that is mapped with librarian_id of the librarian table to create one to many relationship again. Borrow table after normalization 4.4 Physical Design The physical design refers to the creation of the physical tables in the preferred database management system. In database management system there are the specific SQL called Data definition languages (DDL) to create the physical table and establish the relationship between the tables. They are CREATE, ALTER, And DROP. CREATE statement is used to create the physical structure of the table. ALTER statement is used to modify the existing structure of a table as adding and removing columns, constraints etc. DROP statement is used to delete a table. For instance we have to create the tables as per the requirement. Here are the DDL statements to create the tables as illustrated in the ER diagram CREATE TABLE Books ( ISBN INT NOT NULL , book_name VARCHAR( 100 ) NOT NULL , book_status CHAR( 1 ) NOT NULL , book_type INT NOT NULL, book_edition INT NOT NULL , book_publisher INT NOT NULL , PRIMARY KEY ( ISBN ) ); CREATE TABLE Book_Type ( book_type_id INT NOT NULL , book_type_name VARCHAR( 50 ) NOT NULL PRIMARY KEY ( book_type_id ) ); CREATE TABLE Author ( author_id INT NOT NULL, author_fname VARCHAR ( 50) NOT NULL , author_fname VARCHAR ( 50) NOT NULL , author_email VARCHAR ( 100) NOT NULL ); CREATE TABLE Publisher ( publisher_id INT NOT NULL, publisher_name VARCHAR (100) NOT NULL, PRIMARY KEY ( publisher_id ) ); CREATE TABLE Book_Author ( book_id INT NOT NULL , author_id INT NOT NULL ); CREATE TABLE Member ( member_id INT NOT NULL , member_fname VARCHAR( 50 ) NOT NULL , member_lname VARCHAR( 50 ) NOT NULL, member_phone VARCHAR( 25 ) NOT NULL , member_email VARCHAR( 100 ) NOT NULL , member_email VARCHAR( 100 ) NOT NULL , member_type INT NOT NULL , member_address INT NOT NULL , PRIMARY KEY (member_id ) ); CREATE TABLE Member_Type ( member_type_id INT NOT NULL , member_type_name VARCHAR( 50 ) NOT NULL , member_type_allowed_day INT NOT NULL , member_type_fine INT NOT NULL , PRIMARY KEY (member_type_id) ); CREATE TABLE Address ( address_id INT NOT NULL , address_desc TEXT NOT NULL , postcode INT NOT NULL , PRIMARY KEY (address_id ) ); CREATE TABLE Postcode ( postcode_id INT NOT NULL, postcode_description VARCHAR( 10 ) NOT NULL , PRIMARY KEY (postcode_id ) ); CREATE TABLE Librarian ( librarian_id INT NOT NULL , librarian_fname VARCHAR( 50 ) NOT NULL , librarian_lname VARCHAR( 50 ) NOT NULL , librarian_address INT NOT NULL , librarian_phone VARCHAR( 25 ) , librarian_email VARCHAR( 100 ) , PRIMARY KEY ( `librarian_id` ) ); CREATE TABLE Borrow ( borrow_id INT NOT NULL , member_id INT NOT NULL , ISBN INT NOT NULL , librarian_id INT NOT NULL , borrow_date DATE NOT NULL , return_date DATE , expected_return_date DATE NOT NULL , PRIMARY KEY (borrow_id ) ); CREATE TABLE Fine ( fine_id INT NOT NULL , borrow_id INT NOT NULL , librarian_id INT NOT NULL , fine_amount FLOAT NOT NULL fine_paid CHAR( 1 ) NULL , PRIMARY KEY ( `fine_id` ), INDEX (borrow_id) ); Once the table physical structures are created then the relation among them are established as per the ER diagram and normalization. Below are the DDL statements used to create the foreign keys so as to create the relationship between the tables as illustrated in ER diagram. ALTER TABLE Books ADD FOREIGN KEY (book_type) REFERENCES Book_Type (book_type_id) ; ALTER TABLE Books ADD FOREIGN KEY ( `book_publisher` ) REFERENCES Publisher( publisher_id ) ; ALTER TABLE Book_Author ADD FOREIGN KEY ( ISBN ) REFERENCES books( ISBN ) ; ALTER TABLE Book _ Author ADD FOREIGN KEY ( author_id ) REFERENCES Author( author_id ) ; ALTER TABLE Member ADD FOREIGN KEY ( member_address ) REFERENCES Address( address_id ) ; ALTER TABLE Member ADD FOREIGN KEY ( member_type) REFERENCES Member_Type( member_type_id ) ; ALTER TABLE Librarian ADD FOREIGN KEY ( librarian_address ) REFERENCES Address( address_id ) ; ALTER TABLE Borrow ADD FOREIGN KEY ( member_id ) REFERENCES Member( member_id ) ; ALTER TABLE Borrow ADD FOREIGN KEY ( ISBN ) REFERENCES books(ISBN) ; ALTER TABLE Borrow ADD FOREIGN KEY ( librarian_id) REFERENCES Librarian( librarian_id ); ALTER TABLE fine ADD FOREIGN KEY ( borrow_id) REFERENCES Borrow( borrow_id ); ALTER TABLE fine ADD FOREIGN KEY ( librarian_id ) REFERENCES Librarian( librarian_id ); ALTER TABLE address ADD FOREIGN KEY ( postcode ) REFERENCES Postcode( postcode_id) 5 Data Manipulation language Data manipulation language DML is SQL is the statement which used to insert, update, delete and retrieve the data from the table or multiple tables as per requirement. The INSERT statement is used to insert a record in a table. UPDATE statement is used to modify the value of the attribute in a record and DELETE statement is used to delete a record from the table. 5.1 DML to insert dummy records INSERT INTO Postcode (postcode_id ,postcode_description) VALUES (2, NW9 E5J); INSERT INTO Address (address_id ,address_desc ,po

Why the South Could Not Win the Civil War :: American America History

Why the South Could Not Win the Civil War Ever since the day the South surrendered to the North in May of 1865, Americans have argued on why the South lost. Others argued that the South never had chance to win the war, yet more than half a million people were killed, homes were lost and destroyed and families were torn apart. There are many theories to explain this, many arguing that the South never had a chance to win the Civil War to begin with, for the North out numbered and had better resources than the South at almost every point, militarily. Industrially the South couldn't keep up in output of weapons, ammunition and other supplies. That is one of the main reasons the South looked overseas for help. Jefferson Davis knew that the South was at a disadvantage so he looked to England and France. By the end of the war, the South had, more or less, plenty of weaponry still, but it just didn't have enough men to use the guns. By getting either England or France on the Confederate side, supplies would have been more plentiful and also it would have inevitably ended up doing great damage economically to England's maritime trade. However, the fact remained that foreign recognition was denied to the Confederacy in all its attempts. Another reason the South well fell short of a victory was the obvious difference in population between the South and the North. The North at the time had twenty-two million men while the South had a meager nine-and-a-half million, of whom three-and-a-half million were slaves. While the slaves could be used to support the war effort through work on the plantations, in industries and as teamsters and pioneers with the army, they were not used as a combat arm in the war to any extent. This cuts the South's manpower by a third, leaving a fifteen-and-a-half million difference in the population of the two areas. Give the South fifteen-and-a-half million more possible soldiers, and the outcome would have been different. The right military strategy is the key to a war. In order for the South to win the war, they would have needed to apply what is now called a blitzkrieg strategy. This would have been a quick decisive attack on the North to follow up its early victories of Manassas in the East and at Wilson's Creek and Lexington in the West.

The Other Side of Truth

‘The Other Side of Truth’ is a novel written by author, Beverly Naidoo. The novel is mainly based on telling the truth and lying, and when it is right to do either. In the book are various types of situations where characters need to make a decision on whether to lie or to tell the truth. Beverly Naidoo provides the correct decisions and the wrong ones in the story. Naidoo shows in the novel, when it is ok to lie and when it is not. Naidoo suggests that if your life is in danger it is considered ok to lie, but if you assume your life is still in danger when it’s actually not you might accidently lie to the wrong people.Naidoo displays this when Sade and Femi find the father in a detention centre and ask him why he is not able to come back home with them. Folarin says that he cannot because Sade lied about who they were to the officials. Now the officials do not believe Folarin when he says that they are his kids. There is a sthrong message that sometimes one lie i s ok in the right circumstances, but consecutive lies could end you up in a lot of trouble. An important quote from the book states this idea, â€Å"A lie has seven winding path, the truth has one straight road. pg. 148. Lying could be a very dangerous thing, telling the truth is the best way to go, but even the truth can land you in trouble. The truth is a very powerful thing, it is important that you tell it, this is portrayed by Naidoo in her novel. Naidoo has based the whole novel around the truth. In the story it is used when it should and shouldn’t be. Folarin Solaja is the main protagonist in the novel when it comes to the importance of telling the truth. He states several quotes about how important in his mind, it is to tell the truth.

Research Methods in Psychology Essay

The purpose of the sections of a research article should start with a title, author, and contact information. The Abstract is next; this is a summary of the article. The summary provides an general idea of the article, which is helpful to establish if the article is significant to the reader’s investigation. An abstract will usually follow a regular format like APA or something that is similar. The author or authors in brief state why the research article is significant, the methodology, results, and concluding proclamation regarding the results. The Introduction would be how the authors explain the underlying principle for the study by illustrating what research has been completed in the past. A literature review supplies the reader with a outline of other research associated with the article topic, along with addressing questions that are unanswered or investigative need more research. Many questions are also introduced within the introduction, and hypotheses results are declared. Next are the Methods or methodology section. In this section the author or authors summarize how the research was performed. For example, sample, size, and a description of participants. This section will also show how participants were chosen for the study, what was measured and how, along with an explanation of how the data was evaluated. The next section consists of the results. The author or authors will show the research results along with any statistical analyses. Example can be tables, charts, and figures, along with a printed clarification. The Discussion section is the author or author’s explanation and understanding of the results in addition to an explanation of unforeseen results. Finally the conclusion and summary in many if not all articles will explain what the author or authors found and connect it back to the existing literature. Authors can recommend directions for potential research in the conclusion along with referencing back. The references is the last section of an article an lists the publications the authors have cited wthin the research article. References can help the reader critic the validity of the article and can learn more regarding the research topic (Cozby, 2009). What are the steps to critically evaluate research articles and how does the scientific method help you to do this? To critically evaluate research articles the research in the article must be clear in informing the reader of its aims. Terms should be clearly defined, even more so if they’re new or used in specific non-spread ways. You as a reader should pay particular attention should to errors in logic, especially those regarding causation, relationship or association. â€Å"A background in research methods will help to read these reports critically, evaluate the methods employed, and decide whether the conclusions are reasonable† (Cozby, 2009, p. 2). What is the importance of research in behavioral sciences? Today and in the past psychologists and many other professionals use observation to calculate human behavior to better understand psychological and biological processes, motivations, and individual personality traits. Human behavior may be understood through applied and academic science. Using the scientific method is necessary for statistical psychology. According to our text, the importance of research in behavioral science can be the description of the behavior, the prediction of behavior, determining causes of behavior, and understanding or explanation of behavior (Cozby, 2009, p. ). What is the relationship between applied research and basic research? Provide an example, from your selected studies, of how each contributes to the body of knowledge. Psychology became an actual science around the late 19th century, because of the interest of human behavior. Basic research attempts to answer essential inquires regarding the who what were when and why of behaviors. â€Å"phenomena such as cognition, emotion, motivation, learning, psychobiology, personality development, and social behavior† (Cozby, 2009, p. 0). An example article regarding a basic research article can be; â€Å"Artifactual seven-day cycles in spontaneous activity in wild rodents and squirrel monkeys† (Richter, 1976). This article determines the basic processes of activity in behavior and cognition of the mammals within the article. With applied research, this research is â€Å"conducted to address issues in which there are practical problems and potential solutions†(Cozby, 2009, p. 10). Applied research is any kinds of fact assembly assignment or ob that is performed with observing and applying the information found and will concentrate on a specific issue. Applied research can sometimes be simple and sometimes can be complex. An example of an applied research article can be as follows; Making things happen through challenging goals: Leader proactively, trust, and business-unit performance. This is considered an applied research article because it is focused on a specific issue or analogy which is; â€Å"proactive senior managers establish more challenging goals for their business† (Crossley, Cooper, & Wernsing, 2013, p. ). What ethical issues can you identify in the selected articles? How were the issues addressed or neglected? Both articles above did not have any ethical issues. Both did not harm anyone or any animals. Both articles above did not deceive anyone or any animal. Both had legal authority approval. However, as voluntariness, subjects within the wild rodent article could not volunteer because they do not have that option. The participants in the â€Å"Making things happen through challenging goals† article did have the volunteer option. Both articles did not comprise of plagiarism or misleading authorship. All data provided correct and up to date references and proper publication; this was provided at the end.
