Traditional Approaches to Industrial Relations Research Proposal
Traditional Approaches to Industrial Relations - Research Proposal Example If the modern human resource is more equipped, then the fact that today's employees have not remained like their predecessors in following up the traditional managerial authority can also not ignored. Employees are more educated along with the qualities of more likely to question than to accept managerial authority, more focused on their own career development than on the organization's interests, more mobile and are less loyal to their workplaces. Many managers see these characteristics in a negative light and advance them as yet more reasons why performance planning and review won't work. In fact, these characteristics of employees make today's employees 'knowledge' workers and today's human resource 'knowledge management'. The jobs of these 'new' employees present new challenges for managers but, handled effectively, these challenges are a key to better individual and organizational performance. For example, knowledge-based jobs might involve high levels of non-repetitive work, with frequent changes in demand and direction making the prediction and planning much more difficult and uncertain. Other features of knowledge work also have an impact on the management of performance. (Rudman, 2003, p. 17) Amon Among most researchers working in the context of Human Resource paradigm, it is the explanations that matter any link to firm performance is secondary. It is assumed that societies, governments or regions can have HRM practices and policies as well as firms. At the level of the organization, the organization's objectives and the strategy adopted are not necessarily assumed to be 'good' either for the organization or for society. (Millward, 2000, p. 5)

Struth, Thomas (German), The Smith Family, Fife, Scotland, 1989 Research Paper
Struth, Thomas (German), The Smith Family, Fife, Scotland, 1989 - Research Paper Example Today, Struth is recognized as among the very first photographers who heralded contemporary German photography. Struth has had many of his works exhibited in Museums and other exhibition centers around the world. The most recent project which has further boosted his profile is his portrait of Queen Elizabeth II and Prince Phillip, the portrait was part of a collection taken to commemorate the Queenââ¬â¢s 2012 Diamond Jubilee. At the beginning of his photography career, Struth became popular for his ââ¬Å"Unconscious Placesâ⬠photographs; these represented cityscapes completely devoid of life. Part of this collection was on display until November at the Venice Architecture Biennale. Recently, Struth had an interview with Oââ¬â¢ Haghan a reporter with the Guardian newspaper. In this interview, Struth described his preference of photography to painting and also explained the inspiration behind his first photographs which represented skyscrapers. In the interview he explained that he made huge ââ¬Å"super-realist photographic paintingsâ⬠, these never greatly appealed to him and felt they were somehow stupid. This displeasure informed his preference for photography, his tutors and mentors at the time, Richter and Bernd Becher also preferred his photography. Struthââ¬â¢s initial photographs were of his own city, he took photographs of Dusseldorfââ¬â¢s streets and buildings. He explained that his emphasis on building arose from an inquiry on how history would find its place in our current lives, further; he wondered how architecture represents humanity. In answering these questions he found his style and methodology. Just like every artist, Struthââ¬â¢s photographs depict an individual who is largely reactive to the environment around him. This also includes the people he meets and interacts with. He is one who draws great inspiration from life and structures around him. In his own words, the subject of his photographs arises from a need to talk about

Game and Football Team Bonds Essay Example for Free
Game and Football Team Bonds Essay Itââ¬â¢s the most fun, most competitive, team-oriented sport in the earth. We do anything to win a game. Ladies love us guys want to be us. Everybody loves the game, people are always playing it, and it is the soul of the universe. When you put on the pads, lace up the spikes, and buckle your helmet you walk onto the field with a swagger and nothing else matters. You will forget if you failed a test, fought with a friend, or lost some money. Football is the sport I love the most because of three things. The bond on a football team is like no other sport. Another reason is the hardwood and dedication you put in. Lastly why I play football is to win it all The way a football team bonds with each other over the summer and overnight camps is unbelievable. We donââ¬â¢t all hang out with each other on the weekends, but on Saturdays we are a family. If your team wants to be successful you have to trust that the 10 other players on the field will do their job each and every play. Unlike in most sports you need more than one great player on a team, in fact Iââ¬â¢d rather have a team with a bunch of good players. Than have a team with just one or two amazing players. Why do we run back and forth day after day? Hitting and running so hard we ache everywhere. Pushing it so hard we listen to our hearts beat rings in our head, while our lungs desperately gasp for air. Early mornings, late nights, Saturdays and Sundays, an endless amount of pain, deep bruises, broken bones, and torn muscles and ligaments. We hustle thru it all, because we live off our adrenaline, because the game frees your soul, because the party after the big win is spectacular, because you are invincible once you step onto the field. A big play could make you smile all day long and the next day as you joke about it with friends. The rattling of the crowd, the feel of the ball, the image of the spikes in the dirt, itââ¬â¢s a glory to live by. Because it is possible to hustle hard enough you can leave your worries behind. Sweat is the cologne of our accomplishments, Why should anyone push themselves so hard? Itââ¬â¢s not for the money, itââ¬â¢s not for the girls, itââ¬â¢s not for bragging rights, and itââ¬â¢s not for the fame. We do it because we love it. And we love the feel of victory. Thereââ¬â¢s nothing better than after of working your butt of for 3 hours than walking off the field held high. The satisfaction knowing all those sprints and hills you do during the weak all paid off. The feeling that you canââ¬â¢t explain when you beat your cross town rivals knowing you just earned bragging rights for the year. The feeling that you were champions is the one feeling that I am missing I we were won win away from feeling that. But I am going to work hard, so next year I will finally feel what itââ¬â¢s like to be a champion. Why I love the game of football because not everyone can play it. You might be able to play two hand touch with your friends, but can you take the beating? Thatââ¬â¢s the question. Fansââ¬â¢ cheering you on as the fourth quarter is coming to an end in a close game. The greatest game to be played if football, everyone wants to be like us, but fail when they try.
Telling the Truth About History Essay Example for Free
Telling the Truth About History Essay The struggle to find truth in telling the stories of history has been a source of constant debate amongst historians and intellectuals. With the emergence of religious rejection during the seventeenth and eighteenth century Enlightenment, the influence and undoubted supremacy of the heroic model of science provided historians with new ways for obtaining truthââ¬âabsolute truthsââ¬âthrough the dispassionate eyes of a ââ¬Å"heroicâ⬠observer. Although this remains unchallenged for many generations, with the cultural changes and the democratization of education, the idea of an absolute truthââ¬âa universal story of national progress which neglects to encompass the diversity of Americaââ¬âis challenged by post-modernity. In all its pessimisms towards absolute truths and objective knowledge, post-modernism illustrates the importance of and sets the foundation for questioning historical accuracy and the idea of objectivity. Can there be truth when the words and language of the ââ¬Å"objectiveâ⬠observer is unintentionally dripping in their own personal, social, and political agendas? Through the works of Foucault and Deerdas, who get at the heart of this very question, historians are encouraged to reject the Enlightenment project, and look deeper into historical evidence to interrogate the structure and organization of the text, its vocabulary, and hidden assumptions. Although, post-modernityââ¬âa critique of the Enlightenment idealsââ¬âcreates the framework for the questioning of historical accuracy, it is very important to recognize its inability to formulate its own solutions to this historical dilemma. Fortunately, with the succeeding ideas of practical realists, there is a sense of hope and optimism for the future of history and the all-encompassing truths that it can uphold. How did post-modernity challenge the heroic model of science and enlightenment ideals? With the digression away from enlightenment ideals of objectivity, absolute truth, and progress, post-modernists set the tone for a new way of thinkingââ¬âsimilar to the way Enlightenment philosophers challenged the absolutisms of the church. With the new social historians, the American story is challenged by the competing ethnic cultures that didnââ¬â¢t fit into the white-protestant American story, and penetrate below the surface to where the stories of women, slaves, and immigrants had been veiled for so long. The idealized American story ââ¬â a fallacious story of unity and equalityââ¬âhad represented the founding fathers political, social, and religious agendas towards progress and modernity which produced justifications like ââ¬Å"manifest destinyâ⬠. With this new idea of the influence of personal experiences and agendas, even Newton and Darwin are put on the stand, to find that even these so called ââ¬Å"dispassionateâ⬠and completely ââ¬Å"objectiveâ⬠observers had political, social, and religious agendas that greatly influenced their work. This opens the door for the post-modernists attack against the possibility of objective historical or scientific knowledge, reality, and in essence, truth. They deny our ability to represent objective knowledge in any true fashion because of the language barrier which serves, in a sense, as a funnel that reflects every personal, political, social, and religious agenda or experience. Post-modernists, like Foucalt and Deerdas, ââ¬Å"made western man into a modern day Gulliver, tied down with ideological ropes and incapable of transcendence because he can never get beyond the veil of language to the reality ââ¬Ëout thereââ¬â¢Ã¢â¬ . (p. 208) With the conflict between the signifier and the signified, as expressed by Saussure, reality or truth can never be reached because in the process of representing an actual object- or the signified ââ¬â there is a risk of distorting and obfuscating it (p. 214). Objects allow us to create storiesââ¬ânarrativesââ¬â not necessarily accurateââ¬âabout the object and its existence. These narratives are inescapable personal and rely upon the experiences and agendas of the individual creating it. Therefore, language is not a direct correspondence to reality. It represents differences, personal agendas, experiences, beliefs, and power relations and knowing this, according to post-modernists, eliminates the possibility of any kind of reality or truth for both science and history. The post-modern cynicism towards reality, truth and objective knowledge created a new way for writing history. The rejection of the old absolutisms created an opportunity for questioning and discourse of previously accepted historical knowledge. It created a space for the stories of marginalized groups who had until this time, been veiled by the universal, romanticized American story of progress toward modernity. A story of success and opportunity on the frontier was substituted by a story of struggleââ¬âof womenââ¬â¢s rights, of slaves, and of the killings of Native Americans. Within the Enlightenment objectives for history there are limitations to the possibility of anything else but progress. When progress and modernity are the only ideals being stressed, there is little room to create a history beyond this. These ideals consumed the thoughts, beliefs, politics and social structures of man, and it was reflected in their work. History until this time was being tied down and restricted to the old absolutisms, to one universal story which supposedly encompassed all of nature. However, with social history and the door it opened for post-modernity, history could take on the task of telling a more encompassing story that could be discussed, criticized, and built upon. Although, post-modernists believe that there is no truth and that the possibility of reality is non-existent, they set the foundation for future historians to question the history books which they are learning from, to look deeper into the hidden agendas that are sometimes veiled, and to then write a history that, although cannot be completely objective and dispassionate, can embody some sort of truth and historicism for that time. This idea of taking a middle ground between the traditionalist philosophers of the Enlightenment and the pessimistic post-modernists is the main goal the authors of this book try to make. They recognize the need for questioning and interrogation but not to the extent that we end up a nihilistic view that there is no truth and nothing matters. The gap between past events, like records, and the way historians describe and interpret them is accepted by practical realists. This allows for the possibility of obtaining truth and a method for writing history. Some words, they explain, however socially constructed, reach out to the world and give a reasonably true description of its contents because of a relationship between the object and the observer (p. 250). With the practical realists emphasis on archival research, the use of our memories and curiosity, and discourse upon discourse the writing of history is now possible. However, without the post-modernists cynicism and interrogation of the Enlightenment project history may still be a discipline of absolutisms and ââ¬Å"heroismsâ⬠.

Privacy Supportive Geo-Location Search Software
Privacy Supportive Geo-Location Search Software Devika BV 1 Introduction 1.1 Purpose The purpose of this document is to present a detailed description of the Locating Service Similarity with Privacy using queries. It will explain the purpose and features of the system, the interfaces of the system, what the system will do, the constraints under which it must operate and how the system will react to external stimuli. 1.2 Document Conventions 1.3 Product Scope This web application is chosen for an academic study and implementation. Location-based applications utilize the positioning capabilities of a mobile device to determine the current location of a user, and customize query results to include neighboring points of interests. However, location knowledge is often perceived as personal information. One of the immediate issues hindering the wide acceptance of location-based applications is the lack of appropriate methodologies that offer fine grain privacy controls to a user without vastly affecting the usability of the service. In specific, the following are the contributions towards this project. A novel architecture for LBS applications that is directed towards revealing privacy/utility trade-offs to a user before an actual geo-tagged query is made. A proof-of-concept design for a privacy-supportive local search location based search. 1.4 References Exploiting Service Similarity for Privacy in Location Based Search Queries Qin Liu, Guojun Rinku Dewri, Member, IEEE, and Ramakrisha Thurimella IEEE TRANSACTIONS ON PARALLEL AND DISTRIBUTED SYSTEMS VOL:25 NO:2 YEAR 2014 ââ¬Å"Supporting Anonymous Location Queries in Mobile Environments with Privacy Grid,â⬠in Proceedings of the 17th International World Wide Web Conference,2008, pp. 237ââ¬â246. B. Bamba, L. Liu, P. Pesti, and T. Wang 2. Overall Description This section will give an overview of the whole system. The system will be explained in its context to show how the system interacts with other systems and introduce the basic functionality of it. It will also describe what type of stakeholders that will use the system and what functionality is available for each type. At last, the constraints and assumptions for the system will be presented. 2.1 Product Perspective To begin with, this is a very dynamic concept. Usability has a twofold meaning a) privacy controls should be intuitive yet flexible, and b) the intended purpose of an application is reasonably maintained It is worth mentioning that a separate line of research in analyzing anonymous location traces has revealed that user locations are heavily correlated, and knowing a few frequently visited locations can easily identify the user behind a certain trace. The privacy breach in these cases occurs because the location to identity mapping results in a violation of user anonymity. The system attempts to prevent the reverse mappingââ¬âfrom user identity to user locationââ¬âalbeit in a user-controllable manner. 2.2 Product Functions Mobile search is an evolving branch of information retrieval services that is centered on the convergence of mobile platforms and mobile phones, or that it can be used to tell information about something and other mobile devices. Web search engine ability in a mobile form allows users to find mobile content on websites which are available to mobile devices on mobile networks. The first module is to build a mobile search engine with ranking based approach to retrieve results with respect to the localized position of the user. Geo-tagging is a function, where devices can insert metadata with geographical information (coordinates) into a file such as photo, associating it with the geographic location it was taken at. In response to this first query phase, the user obtains a service-similarity profile. This profile is a representation of the similarities in the query output at different geographic locations. The exact form taken by this profile, as well as the data structures employed in computing this profile, may vary from application to application. A location movement engine on the user side then determines a noisy location to use based on the userââ¬â¢s privacy profile and the retrieved service-similarity profile. What is private and what is not private should be actually defined before the query has been raised, this helps the result set not to include those details that are private to the user and thus it would not be shared by the application. The service-contour inferencing is not just a collection of positions, but includes additional information about the businesses located at those positions such as names, addresses, categories, subcategories. Additionally, some specific values such as feedback score, the entire profile of the entity with personal information, so on and forth. The following could be the modules for this project: Login/Register module Search results by ranking module Similarity profiler service module Service-contour inferencing module 2.3 User Classes and Characteristics The user is expected to be Internet literate and be able to register/login and know how to search for information from the system. The user is expected to know how to provide information. The interface, however, provides easy access to all these, nonetheless, the user needs to know the basics to operate and get the best results. The user is expected to be Windows literate and to be able to use button, pull-down menus, and similar tools. There are two types of users who can interact with the system: 1. The registered users who will get access to information of the businesses for a specific location; 2. The business owners who may receive personal information regarding the user at a specific location. 2.4 Operating Environment The following Hardware configuration is expected to smoothly execute the project. Processor Pentium V or above Speed 2.1 GHz or above RAM 1 GB RAM Hard Disk 60 GB Key Board Standard Windows Keyboard Mouse Two or Three Button Mouse Monitor SVGA The following Software configuration is expected to smoothly execute the project. Operating System : Window 7 or above Language : C# (.NET Language) Front End : Visual Studio 2010 Database : SQL Server/Express Web Server :Internet Information Server (IIS 6.0) 2.5 Design and Implementation Constraints Since the application searches data from the database server, it is crucial that there is a good bandwidth/good system resource for the application to function. Data-base search can be laborious when we have larger-data to be executed. 2.6 Assumptions and Dependencies One assumption about the emulator product is that it will be always be used with internet connection, since it has to collect information about a random user moving from the APIââ¬â¢s. It is also assumed that the internet connection is stable during these transactions. If not high, a moderate speed is required to operate with the system. Another assumption is that since the APIââ¬â¢s are third-party services, this could go down or may not work as expected at times. However, it is assumed that the down-time may not be longer enough to disrupt the working of our emulators. 2.7 System Environment 3. External Interface Requirements This section provides a detailed description of all inputs into and outputs from the system. It also gives a description of the hardware, software and communication interfaces and provides basic prototypes of the user interface. 3.1 User Interfaces A first-time user of the mobile application should see the log-in page when user opens the application. If the user has not registered, they should be able to do that on the log-in page. Refer to Fig. 2. If the user is not a first-time user, they should be able to see the latitude and longitude information where the user is current located, see Figure 3. On selecting the user destination, the random movement is simulated and reported by the system. Fig. 2. Login Screen Fig. 3. Current Location Fig. 4. Random User Movement 3.2 Hardware Interfaces No external hardware devices are expected to be used in this project. A system with Windows Operating System running on it should be fine to run the web application. 3.3 Software Interfaces Windows Operating System (OS) XP or 7.0, SQL Server/Express will be used for the database storage. Multiple APIââ¬â¢s and JavaScriptââ¬â¢s would be used in this project. There may be some usage of the web services (as applicable). 3.4 Communications Interfaces The communication between the different parts of the system is important since they depend on each other. However, in what way the communication is achieved is not important for the system and is therefore handled by the underlying operating systems and the database for both the cloud and the web application. 4. System Features 4.1 Login/Registration Module The user should be able to register or login (if already a member) from the mobile emulator. The login/register module helps the user to locate his geo location and will be able to view the businesses/services surrounding the user. The system will also ensure that the privacy details of the user are shared only what is made ââ¬Å"Publicâ⬠or ââ¬Å"Privateâ⬠by the user. Modifications to this sensitive information are provided to the user by the system. 4.2 Search results by ranking module In general, a local search application provides information on local businesses, events, and/or friends, weighted by the location of the query issuer. Location and service accuracy trade-offs are clearly present in a local search LBS. A privacy-supportive variant is therefore well-suited for this application class. Local search results tend to cycle through periods of plateaus and minor changes as one moves away from a specified location. The plateaus provide avenues for relaxation in the location accuracy without affecting service accuracy, while the minor changes allow one to assess accuracy in a continuous manner. Given a search term (e.g. generic ones such as ââ¬Å"cafesâ⬠, and targeted ones such as ââ¬Å"starbucks coffeeâ⬠) and a highly generalized user location (e.g. the metropolitan city), the privacy-supportive LBS generates a concise representation of the variation in the 10-nearest neighbor result set as a hypothetical user moves across the large metropolitan area. Once the representation is communicated to the user, he/she can infer the geographic variability that can be introduced in her location coordinates to retrieve all or a subset of the result set. 4.3 Similarity profiler service module This profile is a representation of the similarities in the query output at different geographic locations. The exact form taken by this profile, as well as the data structures employed in computing this profile, may vary from application to application. A location perturbation engine on the user side then determines a noisy location to use based on the userââ¬â¢s privacy profile and the retrieved service-similarity profile. The LBS processes the query with respect to the noisy location. 4.4 Service-contour inferencing module The result set from the query is not simply a collection of positions, but includes additional attributes about the businesses located at those positions. This could range from names, addresses, categories, subcategories, to specifics such as value, feedback scores, and entire profiles of individuals with personal information. The ranking function is often a well-guarded business secret on how these attributes are combined. Another approach is to send a set of similarity matrices to the user, one each corresponding to a specific co-ordinate in the grid. The approach requires the computation and transfer of an inordinate amount of information. 5. Other Nonfunctional Requirements 5.1 Performance Requirements The requirements in this section provide a detailed specification of the user interaction with the web application software and measurements placed on the system performance. The system on which this client application runs should have installed .NET framework 2. The following software(s) must be installed for smooth implementation of the project. Visual Studio 2012 IIS Web Server/Service SQL Server database Browser application such as Internet Explorer / Mozilla / Google Chrome Windows Mobile Emulator Windows operating system with wired or wireless internet connection 5.2 Safety Requirements All care should be taken to ensure that at any point there is no compromise on the safety requirement during the process of building/executing this project. At this time, there is none that needs serious consideration. 5.3 Security Requirements Database should be password-protected. The system should allow access to users only with a login credentials.

The Neurobiology of Memory and Aging Essay -- Science Scientific Essay
The Neurobiology of Memory and Aging "I lost my keys again," my mother exclaimed at dinner a few nights ago, "I really am getting old." This use of old age as a justification for memory deficits is extremely common. Many people relate old age with loss of memory and other neurobiological functions. Why is it that aging seems to go hand in hand with losing and forgetting things? Is there a neurobiological explanation for this phenomenon? It is clear to neurobiologists that aging results in a decrease in brain size as well as a decrease in the efficiency of brain functions. It has been a widely held belief that aging causes neurons to die and for the overall number of neurons to decrease as one reaches old age. Studies conducted by Dr. David Merrill refute this idea, sighting a lack of neuronal loss in the entohinal cortex after running an MRI on a healthy subject. Instead, Merill indicates that loss of neurons may occur in degenerative disorders, such as Alzheimers, but not in healthy brains. However, it remains true that some aspects of cognition do decline as age increases, such as short term and long term memory. Since these effects are not caused by a decrease in the number of neurons present, there must be another neurobiological explanation. In order to understand memory loss it is necessary to understand how memory works in a normal brain without any cognitive deficits. Memory can be separated into three distinct parts: working memory, declarative memory, and procedural memory (1). Working memory is the most short term, and it involves repeating something that someone has just said in conversation or remembering something you had just seen briefly.
