Denna studie behandlar framställningen av ledare i ledarskapstidskrifter. Studien utgår från ledarbegreppet som en social konstruktion och syftar till att synliggöra vad som ingår i den bild som framställs. Med avseende på ledarbegreppet bidrar framställningen av ledare i media till att skapa föreställningar om vem som kan vara ledare och hur ledare bör vara. Studien avgränsar sig till ledarskapstidskriften Chef. Denna tidskrift har valts genom ett subjektivt urval. Metoden för denna studie är en innehållsanalys samt textanalys av tidskriftens innehåll i form av texter och bilder. Resultatet av denna studie visar att den framställda bilden är relativt snäv. Bilden visar upp få yngre ledare samt ytterst få ledare av någon annan etnicitet än Europeisk och Nordamerikansk. Fördelningen mellan ledare av manligt och kvinnligt kön är relativt jämn under åldern 45 år. Ledare över 45 år är enligt bilden oftare män än kvinnor. Ledarrollen framställs även som problematisk att kombinera med familjeliv och barn för ledare av kvinnligt kön, men inte för ledare av manligt kön. En ledare önskas också ha goda egenskaper inom ett antal olika områden, exempelvis kommunikation, personliga egenskaper samt handlingskraft och eftertänksamhet. Mycket ryms inom varje område och vissa önskade egenskaper står i direkt konflikt med varandra. En ledare önskas med andra ord vara allsidig. Utöver det förväntas ledare inte ha ett uttalat intresse för ledarskap. Ledare förväntas heller inte vara öppna med sitt privatliv varken i offentligheten eller bland medarbetare. Slutligen visar bilden att ledare oftast är verksamma inom stora statliga organisationer eller media. Ledare inom exempelvis tillverkningsindustri får inte utrymme i tidskriften och ingår alltså inte i bilden. Den snäva representationen i framställningen av ledare medför att det för vissa personer saknas förebilder i tidskriften. Detta är en del av det som påverkar hur de upplever sina möjligheter att bli ledare vilket utgör ett problem för mångfalden inom yrkesgruppen.

The purpose of this descriptive study is to examine how two Western women‟s NGOs represent women in the “Third World”. The examined cases are the progressive NGOs Kvinna till Kvinna (Sweden) and the American counterpart Women for Women International (US).Qualitative research methodology has been utilized throughout this study. This thesis is also based on the social theory of constructivism and its ontological assumptions. Since both Sweden and USA are said to be strong promoters of gender equality- a comparative study design, examining two progressive NGOs is one suitable way to analyze the specified research questions. The analysis is based upon the article “Under Western Eyes” (1986) in which Chandra Mohanty discusses Western feminists‟ representation of “Third World women”, summarized in six main stereotypes. Mohanty‟s six claims regarding Western representation of “Third World women” designed the framework that has been used to analyze the collected data, which consists of the two organization‟s own material that is available on their individual websites. The formulated research questions asks whether Kvinna till Kvinna and Women for Women International represent “Third World women” as a homogeneous group sharing a similar experience of oppression in the ways described by Mohanty and if there are any differences in the ways of representation when comparing Kvinna till Kvinna and Women for Women International.

In Corpus Based Knowledge Representation [CBKR], limited association capability, that is, no criteria in place to extract substantial associations in the corpus, and lack of support for hypothesis testing and prediction in context, restricted the application of the methodology by information specialists and data analysts. In this thesis, the researcher proposed a framework called CBKR+ to increase the expressiveness of CBKR by identifying and incorporating association criteria to allow the support of new forms of analyses related to hypothesis testing and prediction in context. <br /><br /> As contributions of the CBKR+ framework, the researcher (1) defined a new domain categorization model called Basis for Categorization model, (2) incorporated the Basis for Categorization model to (a) facilitate a first level categorization of the schema components in the corpus, and (b) define the Set of Criteria for Association to cover all types of associations and association agents, (3) defined analysis mechanisms to identify and extract further associations in the corpus in the form of the Set of Criteria for Association, and (4) improved the expressiveness of the representation, and made it suitable for hypothesis testing and prediction in context using the above. <br /><br /> The application of the framework was demonstrated, first, by using it on examples from the CBKR methodology, and second, by applying it on 12 domain representations acquired from multiple sources from the physical-world domain of Criminology. The researcher arrived at the conclusion that the proposed CBKR+ framework provided an organized approach that was more expressive, and supported deeper analyses through more diagnostic and probability-based forms of queries.

The graph model for conflict resolution (GMCR) provides a convenient and effective means to model and analyze a strategic conflict. Standard practice is to carry out a stability analysis of a graph model, and then to follow up with a post-stability analysis, two critical components of which are status quo analysis and coalition analysis. In stability analysis, an equilibrium is a state that is stable for all decision makers (DMs) under appropriate stability definitions or solution concepts. Status quo analysis aims to determine whether a particular equilibrium is reachable from a status quo (or an initial state) and, if so, how to reach it. A coalition is any subset of a set of DMs. The coalition stability analysis within the graph model is focused on the status quo states that are equilibria and assesses whether states that are stable from individual viewpoints may be unstable for coalitions. Stability analysis began within a simple preference structure which includes a relative preference relationship and an indifference relation. Subsequently, preference uncertainty and strength of preference were introduced into GMCR but not formally integrated. In this thesis, two new preference frameworks, hybrid preference and multiple-level preference, and an integrated algebraic approach are developed for GMCR. Hybrid preference extends existing preference structures to combine preference uncertainty and strength of preference into GMCR. A multiple-level preference framework expands GMCR to handle a more general and flexible structure than any existing system representing strength of preference. An integrated algebraic approach reveals a link among traditional stability analysis, status quo analysis, and coalition stability analysis by using matrix representation of the graph model for conflict resolution. To integrate the three existing preference structures into a hybrid system, a new preference framework is proposed for graph models using a quadruple relation to express strong or mild preference of one state or scenario over another, equal preference, and an uncertain preference. In addition, a multiple-level preference framework is introduced into the graph model methodology to handle multiple-level preference information, which lies between relative and cardinal preferences in information content. The existing structure with strength of preference takes into account that if a state is stable, it may be either strongly stable or weakly stable in the context of three levels of strength. However, the three-level structure is limited in its ability to depict the intensity of relative preference. In this research, four basic solution concepts consisting of Nash stability, general metarationality, symmetric metarationality, and sequential stability, are defined at each level of preference for the graph model with the extended multiple-level preference. The development of the two new preference frameworks expands the realm of applicability of the graph model and provides new insights into strategic conflicts so that more practical and complicated problems can be analyzed at greater depth. Because a graph model of a conflict consists of several interrelated graphs, it is natural to ask whether well-known results of Algebraic Graph Theory can help analyze a graph model. Analysis of a graph model involves searching paths in a graph but an important restriction of a graph model is that no DM can move twice in succession along any path. (If a DM can move consecutively, then this DM's graph is effectively transitive. Prohibiting consecutive moves thus allows for graph models with intransitive graphs, which are sometimes useful in practice.) Therefore, a graph model must be treated as an edge-weighted, colored multidigraph in which each arc represents a legal unilateral move and distinct colors refer to different DMs. The weight of an arc could represent some preference attribute. Tracing the evolution of a conflict in status quo analysis is converted to searching all colored paths from a status quo to a particular outcome in an edge-weighted, colored multidigraph. Generally, an adjacency matrix can determine a simple digraph and all state-by-state paths between any two vertices. However, if a graph model contains multiple arcs between the same two states controlled by different DMs, the adjacency matrix would be unable to track all aspects of conflict evolution from the status quo. To bridge the gap, a conversion function using the matrix representation is designed to transform the original problem of searching edge-weighted, colored paths in a colored multidigraph to a standard problem of finding paths in a simple digraph with no color constraints. As well, several unexpected and useful links among status quo analysis, stability analysis, and coalition analysis are revealed using the conversion function. The key input of stability analysis is the reachable list of a DM, or a coalition, by a legal move (in one step) or by a legal sequence of unilateral moves, from a status quo in 2-DM or $n$-DM ($n > 2$) models. A weighted reachability matrix for a DM or a coalition along weighted colored paths is designed to construct the reachable list using the aforementioned conversion function. The weight of each edge in a graph model is defined according to the preference structure, for example, simple preference, preference with uncertainty, or preference with strength. Furthermore, a graph model and the four basic graph model solution concepts are formulated explicitly using the weighted reachability matrix for the three preference structures. The explicit matrix representation for conflict resolution (MRCR) that facilitates stability calculations in both 2-DM and $n$-DM ($n > 2$) models for three existing preference structures. In addition, the weighted reachability matrix by a coalition is used to produce matrix representation of coalition stabilities in multiple-decision-maker conflicts for the three preference frameworks. Previously, solution concepts in the graph model were traditionally defined logically, in terms of the underlying graphs and preference relations. When status quo analysis algorithms were developed, this line of thinking was retained and pseudo-codes were developed following a similar logical structure. However, as was noted in the development of the decision support system (DSS) GMCR II, the nature of logical representations makes coding difficult. The DSS GMCR II, is available for basic stability analysis and status quo analysis within simple preference, but is difficult to modify or adapt to other preference structures. Compared with existing graphical or logical representation, matrix representation for conflict resolution (MRCR) is more effective and convenient for computer implementation and for adapting to new analysis techniques. Moreover, due to an inherent link between stability analysis and post-stability analysis presented, the proposed algebraic approach establishes an integrated paradigm of matrix representation for the graph model for conflict resolution.

The study of the infinite (countable) family of partial differential equations known as the Kadomtzev - Petviashvili (KP) hierarchy has received much interest in the mathematical and theoretical physics community for over forty years. Recently there has been a renewed interest in its application to enumerative combinatorics inspired by Witten's conjecture (now Kontsevich's theorem). In this thesis we provide a detailed development of the KP hierarchy and some of its applications with an emphasis on the combinatorics involved. Up until now, most of the material pertaining to the KP hierarchy has been fragmented throughout the physics literature and any complete accounts have been for purposes much diff erent than ours. We begin by describing a family of related Lie algebras along with a module on which they act. We then construct a realization of this module in terms of polynomials and determine the corresponding Lie algebra actions. By doing this we are able to describe one of the Lie group orbits as a family of polynomials and the equations that de fine them as a family of partial diff erential equations. This then becomes the KP hierarchy and its solutions. We then interpret the KP hierarchy as a pair of operators on the ring of symmetric functions and describe their action combinatorially. We then conclude the thesis with some combinatorial applications.

On January 12, 2010, the Caribbean nation of Haiti suffered from one of the most devastating earthquake in recent history. The purpose of this study is to explore representations of Haiti in Western news media coverage of the disaster. The researcher utilized Jiwani’s (2006) theoretical framework of common sense stock knowledge to explore the relationship between the Western news media and Haiti, with an emphasis on media framing. Additionally, the method of journalistic discourse analysis was employed as a means of analyzing the 90 article sample. The researcher found that there were several frames that dominated coverage of the disaster which resulted in the marginalization of Haiti and Haitians.

This thesis deals with one important aspect of Artificial Intelligence, knowledge representation and reasoning. Problems like knowledge representation hypothesis, production systems, and the proceduralist and declarativist controversy are discussed. The conventional concept of Al system is based on a model where the reasoning and knowledge base are separate. A different model is proposed in this thesis. In this model, the sensory knowledge is considered the basic elements of the knowledge base, and the higher level knowledge form a hierarchical structure. Reasoning power, in this model, is only part of the, knowledge structure. A frame-based knowledge representation system, WenLy, is presented. It is designed to construct a knowledge base from the bottom up, which is conformed to the proposed model in this thesis. The unique characteristic of WenLy is that its reasoning is accomplished by the code imbedded in the knowledge base instead of a separate inference engine. This is the correct approach according to the knowledge structure model herein proposed. An example of the application is shown. WenLy can be used by a robot to represent the robot's understanding of the outside world. The understanding, however, is limited by the bandwidth of the perception capabilities. It can be shown that the conflict between the declarative and procedural aspects of knowledge can be resolved by following the proposed model.

Title: If you can not be seen - You do not exist: A quantitative study of how gender and other socialfactors affect the degree of visibility in the Swedish newscasts of Aktuellt and Rapport. (Syns duinte � finns du inte: En kvantitativ studie om inverkan av kön och andra sociala aspekter påmänniskors synlighet i Aktuellt och Rapport).Number of pages: 46Author: Helena HuhtaTutor: Martin FredrikssonCourse: Media and Communication Science CPeriod: Autumn of 2009University: Division of Informatics and Media, Uppsala UniversityPurpose/Aim: The aim of this study has been to investigate to what degree women and menparticipate in the newscasts of Aktuellt and Rapport, broadcast on the Swedish public servicechannels of SVT 1 and SVT 2. Furthermore, I have also looked into how social identities, such asage and ethnicity, affect the degree of representation for each gender, respectively. Some of thebasic research questions comprise: 1. how much space is given to men compared to women in termsof: number of participants for each gender, speaking time and position in the news order? 2. Howdo the roles differ for male and female participants in terms of position and topic? 3. How do ageand ethnicity affect the degree of visibility for men and women in Aktuellt and Rapport?Material/Method: This study has been carried out as a quantitative content analysis of Aktuellt andRapport, during ten weekdays in October and November of 2009. The research units included in thestudy consist of all people visible and talking actively, on screen during the domestic news, of saidperiod, in Aktuellt and Rapport.Main results: The results show that men are more visible than women, due to there being a largernumber of male participants, and men also having a tendency to get longer speaking times.Regarding roles, women participate to a much greater extent as private persons than men - the latterrather being made visible as representatives. The main subject areas between the genders also differ, where women usually occur in a “soft news” context, and men in “hard news” context.When looking into the intersection between gender and age, the newscasts have a tendency todisplay younger females and older males. Hence, the female participants seem to have adiminishing chance of being seen as they grow older, while there is an opposite tendency for maleparticipants.Finally, regarding the intersection between ethnicity and gender, the study has shown that thegenders are more evenly represented among people of a non Swedish origin. The ethnic minoritiesare, however, underrepresented in these newscasts as a whole.Keywords: gender, ethnicity, age, intersectionality, news, media, representation.

This study investigates the real representation of women in two villages in Orissa, India. Through my own feminist lens I have brought in theory of spaces of participation and power and hence linked this to the concept of real participation. Women from three different ranges within the local social hierarchies have participated in this study by sharing their knowledge, and I have tried to connect their stories and knowledge to political geography by captivating how they are represented in local governance. Representation is an important concept throughout this study, and it concerns how people feel that their interests are being represented and listened to. The study reveals women’s constrains and enabling factors to participate in formal or public spaces of governance. The studied women show that they lack real access to the invited spaces of participation in their local villages and thus they lack access to real representation through public spaces. This study also investigates the links between different spaces of representation, and shows that real representation is vital in women’s lives. When in practice excluded from the local public spaces of governance, these women claim spaces of participation and power by creating their own spaces of representation in the counter-publics.
