The integration of separate applications means the models are always instantiable. The scope of the model can be the all the data in the applications it incorporates or any data shared between two or more of these applications. Integration data models can also be used to share data between many enterprises. An example of integration models is the Enterprise Data Model (Simsion, 1994).Advantages * Comparison is made easier due to sharing of data * Communication and exchange of information between firms is made easier, especially between a firm and its suppliers * Data that should be held has restrictions and is not easily sharedDisadvantages * There is difficulty in maintaining and supporting the models * There is need to always rebuild the database each time there is a change in data exchange protocol * Accessing and updating the models require a lot of procedure * Application Data ModelsThese refer to data models that relate to a specific application (Simsion, 1994). Examples of application data models include Physical Data Model, Logical Data Model, Conceptual Data Model, and Canonical Data Model (Simsion, 1994). The model is generally a concept of database that represents application entities, the attributes of the entity, and the relations of the entity that are persisted in the schema of the database.Advantages * Helps in providing systematic information regarding a project in the firm * Groups employees so that the supervisors and managers have an easy time in identifying the subordinates according to their skills and experience. * Provide a link for interaction between the employees of a given departmentDisadvantages * Information relating to the skills of the employees as well as the skills required for the projects are uni directional, making it hard for a given employee to determine the employees they can consult in the absence of the managers * Information relation to changes in a project is unidirectional as only the managers or supervisors get such information. * Business Requirement Data ModelsThis model is mainly developed to help in the reflection and capturing the business requirements statement. Making the notion simple and easily understandable during the creation of the model is very significant for the successful use of the model. The fact that this type of data model is developed to form the base for further analysis makes it necessary that it just captures a few necessary details. The model can also be used as an important framework for displaying the rules of the business as a way of defining the types of entity (Simsion, 1994).Advantages * Helps in defining the structure of the organization * Define the business rules to the employeesDisadvantages * Cannot help a firm interact with ano ther * Does not offers interaction between employeesWhen comparison and contrast is done among these groups of data models it is noticeable that the differences that exist is the area the data models target with regard to the organizational activities and the differences in the design of the models to meet their desired functions. On the other hand it is noticeable that the data models have the similarities in the benefits they bring to the organization. All the data models help in improving the quality of data, the definition of the requirements of the business, reuse of assets, reduction of data movement, reduction in the data movement, and reduction in maintenance in the firm.Section 2: Limitations and Benefits of Database TechnologiesThe Advantages * Controlling Data Redundancy: Ensures that all the data within the organization are created in one database and the problem of duplicate copies of data is eradicated. * Data Consistency: Data is easily updated whenever changes occur and thus the consistency is ensured. * Data Sharing: the data in the databases can be shared by as many users as possible provided that they are authorized to access the data. This eases the transfer of data in an organization. * Data Integration: Data is store in tables within the database and there is the possibility to create relationships among the tables. * Integrity Constraints: databases are fit with consistency and integrity constraints rules that ensure that only the correct data is entered in the database all the time. * Data Security: the data in the systems is always protected in a way that it can only be accessed by authorized users of the systems.Disadvantages * Cost of Hardware Software: upgrading both the hardware and the software may be costly as there is a requirement for a data processing of high speed and large memory size. * Cost of Conversion: the data stored in the data files of any system that is computer based must always be converted to the files of the d atabase when a database system replaces the file-based computer system. This process is always difficult and consumes a lot of time. * Cost of Training Staff: application programmers and database administrators and other personnel who are concerned with handling of the system are expensive to train and compensate. * Technical Staff Appointment: It may be expensive and cumbersome to come up with the right staff to manage the systems. It means the company will always hire qualified people who may be expensive to compensate. * Database Failures: all the data is always integrated into one database and any failures due to corruption of the system may lead to lose of some data.Section 3: Example of Database Technologies * Data WarehousingData warehousing refers to database that is used in data analysis and reporting (Teory, 1994). The integration of data from one or many different sources makes a central storehouse of data referred to as data warehouse. The major role of the data warehous e is the storage of historical and current data that the management of an organization uses to create quarterly and annual reports.Benefits of Data Warehouse * Consistent presentation of the organizationà ¢Ã¢â€š ¬s information * Ensure that the data that it restructures make sense to the business users * Makes is easy to come up with the decision-support queries for an organization * Provides a single model for all the data of interest to the organization, regardless of the source of the data. * Improves the quality of the data through the provision of consistent codes and description as well as flagging and fixing bad data.Limitations * Integration of data in a single system may lead to lose of some information when the system becomes corrupt * The process of loading data from different operational system to the data warehouse is complicated especially when integrity has to be maintained. * There is difficulty in the modification of the data warehouse to meet the needs of an organ ization that uses different approaches in handling their businesses. * Data MiningData mining refers to a process of conceptually discovering the patterns that exist in large sets of data through methods of the intersections of machine learning, artificial intelligence, database systems and statistics (Teory, 1994). Data mining has the major goal of extracting the desired information from a set of data and transforming it to a structure that can be easily understood and hence the ease to further use the data.Benefits * Useful in marketing and retail for carrying out market analysis and coming up with the best market segment and entry strategies * It provide financial institutions with information regarding loan repayments and credit reporting * Helps in the detection of faulty equipment and determination of control parameters in manufacturing industries. * Detection of criminal activities and money laundering as well as analysis of the records of financial transactions is achieved b y governments through data mining.Disadvantages * It violates the need for privacy as its widespread makes it easy to get information that may be needed about any given person * Security is an issue too with data mining as one is able to hack into other peoples accounts and still private information that may lead to lose of wealth or lives * The information that is collected for ethical use may be used unethically by other people with ill motives like business gains or discrimination. * Web Enabled Database ApplicationWeb enabled Database refers to database applications that are placed within the interface of the web (Teory, 1994). The web designers design the websites as the database designers make the databases. The two...

Impact of empowerment on the organizational behavior in 5 star hotels Free Essay Example, 1000 words

Whereas a bare approach to Human resources management is a self explained concept without its strategic orientation. It refers to all those activities that are undertaken consciously or unconsciously, internally or externally to an organization whereby human resources of the organization are developed and utilized in a manner to maximize achievement of organizational goals. One important precept of entire human resources' management exercise is the recognition of the fact that the most valuable resource for any organization is its human factor; it is the only live factor and thus the only truly mouldable factor. Therefore human resource management (HRM) is a term used to represent that part of an organization’s activities concerned with the recruitment, development and management of its employees (Wood & Wall, 2002). Employee empowerment is an important piece of strategic initiatives in human resource management in any hotelling organization. Empowerment if adopted as a consc ious strategy has important implications for employee motivation, performance and the quality of the service offered by the hotel. This paper seeks to examine the issue of employee empowerment in some star hotels in Jordan in the back drop of a comprehensive literature review. We will write a custom essay sample on Impact of empowerment on the organizational behavior in 5 star hotels or any topic specifically for you Only $17.96 $11.86/pageorder now The Hotel Industry Parks (2003) states with abundant clarity the role of human interface in hotel industry in following words, † The hospitality industry is obviously customer-service driven. If your employees aren’t satisfied in their jobs, their unhappiness is bound to spill over into their attitudes and behaviors toward clients and guests. Most hospitality positions require people to be in constant communication with the public while servicing guests. Because of this, employee satisfaction is vitally important to the success of your business. Everyone knows that it costs much more to hire and train a new employee than it does to keep an existing employee. However, besides the monetary benefits, tenured employees provide many more advantages to the company. In Adenekan Dedeke (2003) service quality was framed as being dependent on composite results that a service provider and its systems offered a customer. In contrast to the approach that depicts service quality as a discrepancy construct, this paper frames the concept as a fulfillment-oriented construct. Accordingly the underlying variables were defined. To implement a context-dependent Services quality instrument, paper argued for use of a service quality grid to classify firms according to their outcomes and dominant service-encounter interactions.

Beowulf And The Germanic Heroic Code Of Values,...

Every culture has its own set of values, beliefs, and customs. These values, beliefs and customs create each unique culture, and these cultural constructions are directly and indirectly acquired throughout the lifetime of the culture. A major part of culture is literature; the literature of the time reflects upon daily life and society during the time that the story was composed. Beowulf, an epic poem, is one of the most important and only works of Anglo-Saxon literature. Much like a fable, the epic poem of Beowulf had lessons that taught the people within this society how to behave. This essay will outline how the importance of Christianity and the Germanic Heroic Code in Beowulf are revealed throughout the epic poem as important aspects of the Anglo-Saxon culture as a whole. The Germanic warrior society had an unspoken code – a list of rules that warriors and kings alike must uphold. The main aspects of this code for warriors were strength, courage, loyalty and honour; and for kings were loyalty to his warriors, generosity and a sense of responsibility. The character of Beowulf represents both sides of this Code very well. Hrothgar, King of Denmark, represents the nobility’s side of the code: Then Halfdane’s son presented Beowulf with a gold standard as a victory gift†¦ that was both precious object and token of honor†¦ And so their leader, the lord and guard of coffer and strongroom, with customary grace bestowed upon Beowulf both sets of gifts.

How to Prepare a Sodium Hydroxide or NaOH Solution

Sodium hydroxide is a common and useful strong base. Special care is required to prepare a solution of sodium hydroxide or NaOH in water because considerable heat is liberated by the exothermic reaction. The solution may splatter or boil. Here is how to make a sodium hydroxide solution safely, along with recipes for several common concentrations of NaOH solution. Amount of NaOH to Make Sodium Hydroxide Solution Prepare solutions of sodium hydroxide using this handy reference table which lists the amount of solute (solid NaOH) that is used to make 1 L of base solution. Follow these lab safety guidelines: Dont touch sodium hydroxide! It is caustic and could cause chemical burns. If you do get NaOH on your skin, immediately rinse it with a large volume of water. Another option is to neutralize any base on the skin with a weak acid, such as vinegar, and then rinse with water.Stir the sodium hydroxide, a little at a time, into a large volume of water and then dilute the solution to make one liter. Add sodium hydroxide to water--do not add water to solid sodium hydroxide.Be sure to use borosilicate glass (e.g., Pyrex) and consider immersing the container in a bucket of ice to keep the heat down.  Inspect the glassware prior to use to make sure it is free from any cracks, scratches or chips that would indicate a weakness in the glass. If you use a different type of glass or weak glass, theres a chance the temperature change could cause it to shatter.Wear safety goggles and gloves since there is a chance the sodium hydroxide solution could splash up or the glassware could break. Concentra ted solution of sodium hydroxide are corrosive and should be handled with care. Source Kurt, Cetin; Bittner, Jà ¼rgen (2006). Sodium Hydroxide. Ullmanns Encyclopedia of Industrial Chemistry.

The Great Depression and World War II Shaped My Grandmas...

The Great Depression and World War II Shaped My Grandmas Life My grandma, Alma Jean, was born in 1935 in Silo, Oklahoma, just outside of Durant. Her birth certificate says she was born in Durant because Silo was too small to be considered a real town. She lived there on a farm with her parents, Orval and Maggie Dale. It was the middle of the Great Depression, and they were a farming family at a time when it seemed like no one could make a living off the land. To supplement their income, Orval and his father worked for the Works Progress Administration (WPA). President Roosevelt set up the WPA the same year that my grandma was born (Divine 760). The WPA was similar to other work relief programs such as the CCC, PWA, CWA and NYA.†¦show more content†¦Her dad would sell the skins from the animals he caught. One winter, Maggie (his wife), used the money to buy my grandma a new red coat. However, despite their efforts, the family couldnt afford to stay in Oklahoma. Like many families during the Great Depression, they had to move to survive. In 1933, there were 5,190 bank failures in the U.S. (Divine 755) and unemployment was at 25 percent (Conlin 684). In 1930 a drought hit much of the South and Midwest. It lasted ten years and turned Americas farmland into an unproductive wasteland (Current 737). The drought area came to be known as the Dust Bowl (736). This, combined with the high unemployment and collapsed economy of the Depression, forced families to leave their farms in search of work. In 1932, one in four families living in the Dust Bowl was forced off its land (Conlin, 685). Most of them headed to California (686). They were called Okies and once they got to California, things usually werent much better. Work was hard to find, and because of Californias seasonal crops, it didnt last long. They lived migrant lives, following the crops. The wages were low and many employers found ways to cheat workers out of the little they did earn. Most of the Okies were homeless. They were despised and persecuted by police and native Californians (Current 738). My grandmas story, however, isnt as grim. In 1941, when my grandma was in first grade, they decided it was time to leave.

Seeds as Purgative Extender for Pulvoron Akapulvoron: A Sensory Analysis Akapulko (Cassia alata L. ) Seeds as Purgative Extender for Pulvoron Karl Ericson Landrito Rochelle Gel Asilo Ludy Anne Castrence Maegan Morales Keith Louise R. Salazar Research Adviser: Mrs. Ma. Regaele A. Olarte A. Background of the Study Children during their early stage of learning are curious on how things around them work. They always want to play outdoor games such as  tumbang preso,  patintero,  piko,  jolens,  pogs, and many other games with their playmates. These games require touching and a lot of barefoot running. Children do not tend to know that running barefooted will cause the formation of ascaris and other parasitic worms that might infect their intestines. Malnutrition surrounds our country today; a lot of people, most especially the children, were the victims of it. One of the most common causes of malnutrition of children is worm infestation. Worm infestation can result if there happened to be a direct or indirect contact with the feces of an infected person. It can be dispersed when the feces of an infected organism are used as fertilizers in farmlands that are now converted into urban type of community. The kids that are living in that converted area can accumulate the infection that the former farmland has. Children that are infected can have parasitic worms inside their bodies. They can eventually experience malnutrition and other health deficiencies if not treated. Purgative medicines are cheap in cost but children dislike the taste because of its bitterness. The researchers came up with this project due to the desire of helping the parents of infected children in convincing their kids to take good-tasting purgative remedy that is cheaper in cost and can be done at home. The researchers found out that pounded and boiled akapulko seeds are used as an effective purgative agent. Akapulko is an herbal plant that can be used in curing skin, stomach, lung, and mouth problems, and  is well known for its sudorific, diuretic and purgative characteristics. It can be ingested without having any side effect or contraindications. The researchers thought of pulvoron, being a healthy, delicious, and attractive treat for all. The akapulko seeds were consider as extender in place of the traditional rice crisps, nuts, or nougats in the pulvoron. Established that akapulvoron could be an effective and safe purgative treat, the researchers intended to conduct a sensory analysis of the product to determine if it would be generally accepted by the public. 0 comments Email ThisBlogThis!

Geroche, Sheila Mae T. Pinote, Lorraine Angela D. (Researchers) Mrs. Ma. Regaele A. Olarte Research Adviser) Significance of the Study The augmenting number of Dengue cases not only in our country but also to other countries all over the world experiencing the abnormal change in weather is not of recent origin to us. Along with this difficult situation, there are two-winged, dipterous insects that hatch their eggs for a short time, reducing the size of their larvae and become â€Å"nervous-biters†. In that case, they are harder to in tercept in flight that is why it is more advisable to focus on the places where they lay their eggs. The researchers conducted this study in order to lessen the proliferation of mosquitoes or prevent the eggs from hatching using the Makahiya  Mimosa pudica  roots extract as an ovicide. As the experiment was proven to be effective, it is relevant to propagate the plant for mass production and communicate the results to other people. It is also significant to conduct experiments about the other potentialities of   the said plant, such as the anti fertility property of its root extract which was   proven in Albino white mice sperm cells according to Dr. Godofredo Umali-Stuart of University of Santo Tomas. comments Email ThisBlogThis!

Regaele Olarte Statement of the Problem The study sought to devise a system to protect every computer from hacking and unwanted file sharing due to usage without permission by unauthorized users. The researcher utilized fingerprint-based biometric security system on the power switch of personal computer, thus making it unquestionably â€Å"personal.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Specifically, the study aimed to answer the following questions: 1. How should the system be designed and developed in order to: a. Secure the user’s data from hacking or sharing, b. Provide an account security for the computer user, c. Ensure that the system is protected against alteration and not prone to errors? 2. What is the level of performance of the system based on the following criteria: a. Reliability b. Accessibility c. Efficiency d. Functionality? Hypothesis The fingerprint-based biometric security system on personal computer with remote access for the private user is  effective in terms of the specified criteria. Scope and Limitations The fingerprint-based biometric security system on personal computer is more accessible, secured, accountable and accurate. It is in the registered fingerprint where an account is created for hassle-free admission to the system. Furthermore, transactions do not consume much time and effort since the information needed to connect and to access one’s account is already automated. The following were the scope and limitations of the study: * The study only focused on the general transaction of database and of safe-keeping for the data-security of personal computers. This mechanism was not advisable for shared computers but merely for personal use, as only an authorized person could gain access on the most important data and information stored in the computer. * The system would not operate if the user is unauthorized or unregistered. Only authorized user with registered thumb mark and password can get into the system. * This device can register and hold up to five authorized users only to access the system. * The fingerprint-based power switch can also be used on any technology containing switch.

Regaele A. Olarte (Research Adviser) ABSTRACT Water hyacinth is an aquatic plant which could well be used, instead of wood, in generating an alternative source of energy. The processing of water hyacinth into briquette would have a significant role not only in the development of an alternative fuel, but also in the preservation of the environment. The water hyacinth that was harvested, dried, and pulverized was mixed with cassava starch and acacia seed binder by being compressed into briquettes in a manually-operated machine. The experimental set-up made use of dry and fresh water hyacinth while a traditional charcoal served as the control. In all the quality tests done, T- test showed that there was no significant difference between the experimental product and the commercial product in terms of various parameters, at 0. 05 level of significance. The results of experimentation and data analysis showed that the experimental product is just as effective as the commercial briquette, with better potential of helping the environment by reducing the negative consequences brought about by water hyacinth’s rapid profusion. Thus, the  environmental briquette made from water hyacinth with acacia seeds as binding agent could be an effective alternative to the traditional charcoal made from burning of wood. 1 comments Email ThisBlogThis!

Background of the Study Official figures show that plastics make up around 25%  of thegarbage that metro manila churns out, while an  independent surveyconducted by Ecowaste Coalition and  Greenpeace on the compositionof discards on manila bay  in 2006 found that  51% were plastic bags,19% sachets and junk  food wrappers, 5% Styrofoam, 1% hard plastics,10% rubber, 13% biodegradable wastes (Cayetano, 2008;www. enatorpiacayetano. com/psc/pressreleasedetails. php? recordID=175)Biodegradable plastics are degradable plastics on which thedegradation results from the action of naturally occurring micro-organisms such as bacteria, fungi , and algae (info@epi-global. com). These plastics are broken down into  water, carbon dioxide, methaneand biomass  primarily t hrough enzymatic action on microorganisms(Azios, 2007www. csmonitor. com/2007/1219/p16s01 -sten. html). Biodegradable will fully disintegrate in six months or  less. It turns intopowder and blends with  the soil after a few months  (Demetillo, 2008www. mprime. com/News. php? BlurbID=1113). Many biodegradable plastics will decompose in  industrial plants,backyard compost piles, or open  environments. The  inherentbiodegradability of plastics depend on  several environmental factorssuch as moisture, temperature, surface area, and the manufacturingmethod of the finished  product. (Nolan-ITU Pty Ltd, 2002www. environment. gov. au/settlement/publications/waste/deg) Although some brands claim to be biodegradable in open air andsaltwater, virtually no decomposition occurs within a closed landfillthat has been  capped, preventing air circulation. Azios, 2007www. csmonitor. com/2007/1219/p16s01 -sten. html)  The  SM  mall  chain  has  started  shifting  biod egradable  plasticbags for its supermarkets and department stores (Cayetano, 2008).

Question: Examine and discuss the reasons why Katzmann, Griffiths and Wigney JJ decided as they did and the implications of this case in terms of valid visa applications. Did their Honours employ any principles of statutory interpretation ? Answer: The issue that the code was required to decide in this case was if a valid visa application has been made.According to the Regulation 2.10 of the Migration Regulations, it is required that a particular visa application has to be made "at the office of immigration in Australia". In this case, the visa application made by the applicant reads the GPO box by express post before the relevant deadline expired. However the department did not collect the visa application until the deadline for the same has been expired. Therefore, the court was required to decide if the GPO box of the department can be considered as the "office of immigration" or if it can be considered as a part of the office of immigration.At the same time, if GPO box cannot be considered as the office of immigration, it was required to be decided if the applicant has substantially complied with the requirement. In this way, the applicant had deposited the visa application at the GPO Box that has been specified by the Department of Minister for Immigration and Border Protection while migration regulationrequired that the visa application has to be made at the office of Immigration in Australia. In this regard, the reasons given by the Court were that the GPO box was leased by the Department of Immigration and Border Protection for receiving the visa applications and therefore it can be considered as a "place for transactions of business" or in the alternative, the GPO Box can be considered as "a place for business" for the department or a place where the business of the department is carried on.The department has leased the GPO Box for receiving written applications for the grant of visa. Arrangements have been put in place by the Department that the visa applications and shall be collected from the GPO Box and the same will be delivered that the Processing Center of the Department where the officers of the Department process all the visa applications. Although it has been mentioned on the website of the Department that the relevant visa applications can be made by other methods like facsimile, courier or these applications can also be made online, it needs to be noted that the applications can be made by posting the same to the GPO box that has been nominated by the department in this regard. As a result, the Court accepted the submission of the applicant that even if GPO box cannot be considered as a stand-alone office of the Department for the purpose of regulation 2.10,it needs to be considered as a part of the office of the Department of Immigration. As a result, it was stated by the court that the GPO box can be considered as an 'Office of Immigration' and therefore, it can be said that the application that has been received in the GPO box needs to be considered as an application that has been made at the office of Immigration. On the other hand, the court did not accept the submission of the Minister that satisfactory evidence was not present that can establish that GPO box has a stable physical existence like any other "place". In this regard the court considered the evidence given by the ACDC manager regarding the Express Post Service of Australia Post and how it receives, sorts and delivers the items. In case of certain specified routes, next business day delivery has been guaranteed by Australia Post in case of all the Express Post envelops that have been lodged correctly on a business day. In this regard, the manager of ACDC also gave evidence that the GPO box number 2399 in Adelaide has been leased by the Department of immigration from Australia Post. All the items arriving at the ACDC were scanned on their arrival and then these items were transferred to the relevant area and sorted so that they can be sent to their destinations, including the post office boxes. It was also stated that once an item has been placed in the post office box, it is not any more under the control of Australia Post. At the same time, an employee of a company named Converga gave evidence that they had a contract with the Department of Immigration and collected mail from ACDC every day and delivered it to the department. This evidence was considered as sufficient to rebut the contention of the Minister of Immigration that no sufficient evidence is present which can establish that the GPO box of the department has a stable physical presence like a 'place'. As a result, the court stated that the GPO box can be considered as a place which can be leased and where mail can be delivered physically and at the same time it can be collected from this place. In the same way, the court also accepted the summation of the applicant that the specification of the GPO box by the Department in the relevant booklet and its letter amounts to evidence that supports their main contention that the GPO box is at least a part of the office of the Department for receiving the applications. As a result, this submission was accepted by the court. By applying the principles of golden rule of statutory interpretation, the court stated that the doctrine of substantial compliance was not applicable in the case.The question is that of construction if an act that has failed to comply with the condition regarding the exercise of statutory power is invalid and therefore of no effect. In this regard the court stated that the language of regulation y2.10 provides no scope for substantial compliance doctrine. These were the reasons due to which Katzman, Griffiths and Wigney JJ arrived at their conclusion.
