Social identity theory (Tajfel & Turner, 1979) is one of the most influential social psychological theories of group behavior and intergroup relations. Early social identity research focused on many different group processes; however, the motivation behind group identification was not fully explored. Researchers have proposed a variety of accounts for why people join and identify with groups. This dissertation unravels the relationship between, on the one hand, mortality salience, self-related uncertainty and self-esteem, and on the other group identification and ingroup defense. The general hypothesis derived from uncertainty-identity theory (Hogg, 2010) is that uncertainty and not fear of death or pursuit of self-esteem motivate people to identify with and defend their groups, and that identification mediates the relationship between uncertainty and defense of the group. Experiment 1 (N = 112) tested the relationship between uncertainty and self-esteem on defense of the ingroup, with the additional test of the mediating effects of identification with the group between uncertainty and ingroup defense. Results showed that uncertainty and not self-esteem motivate people to identify with a group, to defend their group, and that group defense is mediated by identification. Experiment 2 (N = 112) provided a replication of the typical TMT study, which suggests that self-esteem will buffer the effects of mortality salience on ingroup defense, with the additional test of the mediating effects of identification between mortality salience and defense of one's group. As predicted, mortality salience only increased identification and defense of the group when self-esteem was not enhanced, as well, the interactive effects of mortality salience and self-esteem on defense was mediated by identification. Experiment 3 (N = 294) was a combination of both Experiments 1 and 2 and tested the hypothesis that uncertainty would moderate the relationship between self-esteem and mortality salience on group identification and ingroup defense. Exactly as predicted, only under high uncertainty the typical TMT results are demonstrated. Results across these three experiments demonstrate that self-uncertainty plays a significant role in reactions to mortality salience, and support uncertainty-identity theory's analysis of the role of self-uncertainty in ideological conviction and group behavior.

Democracy Now! is an independently syndicated hour long daily audio and video program that is broadcast on 1179 radio, television, and internet stations throughout the world, as well as being freely available on their website under a Creative-Commons License. They are a global news organization based in New York City, with the stated goal of providing “rarely heard” perspectives in their coverage. Democracy Now! was one of the early independent news organizations to provide continuous coverage of the Occupy Wall Street protest in New York's Zuccotti park. Their early coverage of the movement is relevant to the extent that it helps to obviate the demographics of the OWS movement as well as highlight the potential for a “radically-democratic agonistic pluralism,” as conceptualized by Ernesto Laclau and Chantal Mouffe. Through the dual frames of discourse and intersectionality theories, this qualitiative study examines the coverage of Occupy Wall Street by Democracy Now!, in an attempt to understand the interplay of the movement's demographic heterogeneity and the manner in which its public antagonism is characterized by this independent media outlet. The sociopolitical and historical context provided by Democracy Now! is used to understand where the outlet exists with in the media as well as if this coverage can be part of “radical democratic possibilities.”

The focus of this research is on the specific relational and particular circumstances that result in an emerging cancer identity expressed through the daily lived- experiences of emerging adults via personal weblogs. Identity, a complex term in its own right, is discussed here under the rubric of social identity as processual, therefore it is expected that an emerging cancer identity will develop as the participants begin to narrativize their daily experiences with cancer on their weblogs. By critically engaging with notions of emerging adulthood theories with theories on the sociology of death and dying and illness narratives, this research seeks to understand the specific psychosocial changes that occur as the participants engage with their illness on their weblogs, which arguably contributes to an emerging cancer identity.

<p>This dissertation proposes that party identification, as a social identity, fundamentally alters individual processing of and reactions to political information and events. I present a <italic>party identity linkage theory</italic> in which I argue party identity can lead to heightened, specific emotional responses to threatening political competition and biased, polarized perceptions of politicalized objects if the link between self and party is sufficiently strong. Because people are strongly motivated to protect the positive perceptions they have of themselves, they should be motivated to maintain and protect their positive perceptions of groups that are linked to their self-concept through social identities. Furthermore, because people tend to engage in self-serving biases that result in a degree of positive illusions about themselves, especially when the positive self-view is threatened, evaluations of closely linked groups should also be subject to a degree of positive bias, especially when the positive image of the group is threatened. Drawing on both experimental and survey data, I provide evidence that strong partisans are fundamentally different from weak partisans and independents in the degree a party is included in their self-concepts, in their responses to candidates' changed party status, and in their responses to threatening inter-party competition.</p> / Dissertation

Begreppet organisationsidentitet har vuxit i popularitet, både som teori för forskare och som strategi för företagsledning. Samtidigt ser vi en trend på den svenska arbetsmarknaden där det blir allt vanligare att hyra in arbetskraft istället för att anställa direkt i organisationen. Men vad händer med organisationsidentiteten när de anställda är tillfälligt där och dessutom har en dubbel organisationstillhörighet, både till konsultföretag och till kundföretag? Den här studien riktar in sig på konsulternas upplevelser av organisationsidentitet. Syftet är att bidra med kunskap till det teoretiska begreppet organisationsidentitet som tidigare inte har inkluderat tillfälliga medlemmar i en organisation, som till exempel konsulter i bemanningsbranschen. Detta kan förhoppningsvis ge uppslag och väcka intresse för vidare forskning på ämnet. Fem intervjuer med konsulter genomfördes för att undersöka deras upplevelser av rollen samt relationen till både konsult- och kundföretag. Resultatet analyserades i relation till social identity approach och forskning om organisationsidentitet. Slutsatsen blev att alla fem respondenter upplevde en svag identifikation med sina arbetsgivarorganisationer till följd av tillfällighet och en känsla av utbytbarhet. Respondenternas egna reflektioner av vad de tyckte var viktigt för att kunna identifiera sig kretsade nästan uteslutande kring ett behov av att bli sedd av arbetsgivarna, till exempel genom att få uppskattning, stimulans, möjlighet till att utvecklas och samhörighet med kollegor. Dock menade respondenterna att detta inte är något de förväntar sig ska uppfyllas i rollen som konsulter. Istället uppgav alla att de strävade efter en fast tillsvidareanställning där organisationsidentitet skulle spela större roll. / The aim of this stdy is to gain a greater understanding of the situation of temporary workers when it comes to organizational identity, since the research is limited in this field. Five interviews were made with young temporary workers. The interviews were then transcribed and analyzed with the theoretical framework of social identity approach and research on organizational identity. The interviews showed that all respondents felt disidentification or ambivalent identification towards both consulting agencies and the hiring companies, because of the interchangeability and temporal circumstances. They all expressed a need to be seen as individuals, but in different ways they also said that they did not expect that need to be met as long as they were temporary workers. All respondents expressed an aspiration for a permanent post where they thought their needs would be better fulfilled.

This study examines football fan identity and identification within the Nationwide football league in England. A preliminary examination of the literature concludes that research on fan identity with sports teams in general, focuses primarily upon the behavioural consequences of fan identification. More specific research on the football fan concentrates predominantly upon either the F.A. Premier League or the deviant fan. The research thus attempts to fill a void in knowledge by examining football fan identification of fans of less successful football teams, using a social identity theory framework. Employing a mixed-methods research design, and an embedded case study approach, the study investigates those factors that influence fan identification at Luton Town Football Club. Methods used were those of observation/participant observation, a large scale fan survey, and indepth semi-structured interviews with fans. As part of the fan survey, the sport spectator identification scale (Wann and Branscombe, 1993), revealed a fan population that was highly identified with Luton Town. Levels of fan identification were similar across age, gender, and length of support of the club. Subsequent survey and interview data allowed six themes related to this fan identification to emerge: these being the extent of fan identification; the antecedents of fan identification; the maintenance of fan identification; the effects of fan identification upon behaviour; the influence of the cultural identity within which fan identities are enacted; and the relationship between the fan and the football club. Analysis of these themes yields a model of football fan identification which can be adapted to fans of other football clubs, or fans within other contexts. It was concluded that whenever such identification provides positive social and psychological consequences for fans, levels of identification with the club remain high. For these fans, it is the process of identification with the club that is the most important component of fandom. By contrast, where the individual derives fewer benefits from fandom, identification remains low. For such less identified fans, other factors, such as the quality of facilities or team performance, become more meaningful. The findings from the study indicate that social identity theory is an appropriate framework with which to explore the concept of football fan identification.

This thesis provides an analysis of the history and social context of the labret (lip plug) on the Northwest Coast of British Columbia over the last 5,000 years. Although labrets have typically been characterized as markers of ‘status’ with connotations of gender, the variability in observations made by early explorers and ethnographers suggests that this simplistic depiction belies a complexity in what aspect of social identity this form of personal communicated. Therefore, this research has sought to explore the relationship between labrets and social identity by conducting a comprehensive typological analysis by which to examine patterning in materiality through time and space. Although hindered by a lack of temporal data and contextual information on gender association, the results of this research demonstrate that there is geographical patterning at multiple scales—regional, sub-regional and even on the village or site level—which supports the hypothesis that the labret has been an exclusionary tradition conveying both individual and group social identity that varies through time and space in this region. The social meaning of labrets is further explored through research on contemporary labret use, which highlights a tension between individual expression and group acceptance that is expressed materially, contrasting the physical permanence of the labret and the mutability in social meaning conveyed. Finally, interviews with First Nations artists who include labrets in their art has shown that cultural identity both informs and is informed by a concept of shared heritage; thus, the labret is a symbol and expression of social identity that continues to hold significant meaning for the descendants of this heritage. Therefore, while simple correlations of the labret with ‘status’ and ‘gender’ are not wrong, nonetheless they betray the complexity of body ornamentation which, though manifested materially, is highly contextual. This research contributes to the ongoing anthropological discussion of materiality and identity, considering the ways that structured style is negotiated through practice, and asking whether this recursive, dynamic and dialectical relationship can be accessed archaeologically—a task that ultimately requires a commitment to reflexivity, multivocality, and critical examination of the research process itself.

This thesis examines the construct of Psychological Sense of Community (PSOC). Within the discipline of community psychology, there is debate as to the dimensions underlying the construct PSOC. One of the few theoretically proposed structures is that put forward by McMillan and Chavis (1986), who hypothesized four dimensions: Belonging; Fulfilment of Needs; Influence; and Shared Connections underlying PSOC. Further, there is some deliberation in the literature as to the existence of PSOC in relational, as well as geographical, communities. Discussion has also emerged regarding the role of social identification within PSOC. It has been suggested that differences in PSOC may be understood in terms of the degree to which members identify with their community (Fisher & Sonn, 1999). However, few studies have explored the place of identification in PSOC. In addition, while PSOC has been applied to both relational and geographical communities, little research has looked in depth at PSOC within relational communities. Thus, the principle aims of the current program of research were to elucidate the underlying dimensions of PSOC and their consistency across geographical and relational communities. Further, the research also aimed to explore the role of identification in PSOC. The first stage of this research endeavoured to clarify the underlying dimensions of PSOC by utilising a questionnaire which included multiple measures of PSOC and social identification, administered to both relational and geographical community members. The first paper of the current research explored PSOC in a relational community, science fiction fandom (N = 359) and the third paper in a sample of residents of rural, regional and urban geographical communities (N = 669). In both the relational and geographical communities, support emerged for McMillan and Chavis' (1986) four dimensions of PSOC. In regards to identification, the Sense of Community iv affective and ingroups ties aspects of social identification were subsumed within the PSOC dimensions; however, the Conscious Identification aspect emerged as separate to the existing PSOC dimensions. The study presented in paper three also examined the role of demographic factors in predicting PSOC in geographical communities. The demographic factors significantly associated with PSOC were: type of region, with rural participants displaying higher PSOC than their urban counterparts; participation in local organizations; having children; and a vision of one's neighbourhood as broader than just a street or block. To date, little research has compared a single group's PSOC with a relational community to their PSOC with their geographical communities. The second paper presented in this manuscript explored PSOC with participants' relational and geographical communities in the sample of members of science fiction fandom (N = 359). All the PSOC dimensions and Conscious Identification emerged as significant predictors of overall sense of community in both community types. Participants reported higher levels of global PSOC with fandom than with their geographical communities, a pattern that also emerged across the four dimensions and Conscious Identification. It was proposed that the degree of choice of community membership may be one reason for this finding. However, stronger conclusions could not be drawn from this study as situational salience may have influenced the results as data was collected in the relational community context. The second phase of the current research aimed to validate the multidimensional nature and related measures of both social identification and PSOC. The fourth paper presented in this thesis examined the construct validity of the three-factor model of social identification as measured by the Three Dimensional Strength of Identification Scale proposed by Cameron (1999, 2004). The 12 item version of the scale was used to collect data from an undergraduate sample (N = 219) to assess their social identification across three distinct group memberships (sex, student and interest group). This data was subjected to confirmatory factor analysis to examine the fit of the three-factor model of social identity in comparison to fit indices for one and two-factor models. The results indicate that the three-factor model was the most parsimonious and best fit to the data across all groups. In addition, the fact that different patterns of means and correlations emerged across groups on the three dimensions provided further evidence for a multidimensional model of social identification and, moreover, the greater depth of exploration it allows. The fifth paper examines The Sense of Community Index (SCI), one of the most commonly used measures of PSOC. There is much discussion in the literature as to the validity of the scale as a measure not only of overall PSOC, but of the dimensions (Membership, Influence, Needs fulfillment and Emotional Connection) theorized by McMillan and Chavis (1986) to underlie the construct. This paper examines the factor structure of the Sense of Community Index in a study (N = 219)that examined neighborhood, student and interest group communities. The results showed that the Sense of Community Index, in terms of its original factor structure, did not adequately fit the data. The scale was revised, utilizing confirmatory factor analysis indicators, to produce a new four-factor structure based on the original items. This revised model was tested and found to display adequate fit indices to the data in all three community types. The results of the study provide empirical support for retaining measures that encapsulate the four dimensions of PSOC.The sixth paper further explores the interplay between PSOC and the dimensions of social identification. In particular, the study (N = 219) examines the relative strength of the separate aspects of social identification (based on Cameron's 2004, Three Factor Model of Social Identification) as predictors of overall PSOC, accounting for situational salience. Results indicate that Ingroup Ties is consistently the strongest predictor of PSOC and that the strength of Ingroup Affect and Centrality alter according to the group or community context. The seventh and final paper from the current research program emerged from the results of paper two indicating that choice may influence individuals' social identification and PSOC with their respective communities. The study presented in this paper examined participants' (N = 219) level of social identification and PSOC across multiple group memberships that differ in the degree of choice associated with membership (low choice: neighborhood community; medium choice: student community; and high choice: self chosen interest group). Results indicated that, controlling for contextual salience, choice was positively associated with levels of social identification and PSOC. Overall, the current program of research provides some important findings which add significantly to the theoretical understanding of PSOC in today's society. The research provides clarification of both the dimensions underlying PSOC, their application to both geographical and relational communities and the measurement of overall PSOC and these dimensions. Further, it provides empirical evidence of the importance of the Centrality aspect of identification in PSOC in both geographical and relational settings. The theoretical and practical implications of the findings of the overall program of research are discussed.

Given the important role that trust plays in acceptance of water management schemes, the current research investigated the characteristics and determinants of trust by developing a social-psychological model of trust in the area of water management and reuse. The research advanced a theoretical understanding of trust by using social identity theory and the relational model of trust as a framework and providing a systematic examination of the relationships between the variables in the hypothesised trust model. The proposed trust model was tested across three potentially different perceived risk contexts; low, medium and high. Analysis through path modelling provided strong support for the hypothesised model. In all three contexts trust in the water authority was a significant predictor of acceptance of the water management scheme, and risk perceptions mediated the relationship between trust and acceptance. In other words higher levels of trust in the authority were associated with lower perceptions of risk, which were in turn associated with higher levels of acceptance. In Study 4, which was set in the high perceived risk context of the proposed indirect potable reuse scheme in Toowoomba, perceptions of risk had the strongest direct effect on acceptance of the scheme, and the trust, risk and acceptance relationship was stronger than it was in the other studies. The relational variables of procedural fairness, identification with one’s community, ingroup membership of the water authority and a social bond (shared values) with the water authority were all found to impact on trust, either directly or indirectly. In addition, the instrumental variable of the credibility of the authority (measured as technical competence and a lack of vested interests) was found to have a significant impact on trust. Taken together, the results provide support for social identity theory and the relational model of trust as a framework for understanding trust in authorities. The results are also consistent with literature that suggests that the relational and instrumental models of trust are not incompatible (e.g., Edwards & Kidd, 2003; Tyler & Kramer, 1996). The findings from this research program clearly have a practical application for improving acceptance of water management schemes. The combined results demonstrate the importance of trust in the water authority in reducing perceived risk and thus increasing acceptance of schemes. The results highlight the need for water authorities and policy makers to build public trust through procedural fairness, building a sense of the water authority as a member of the community, and through demonstrating technical competence and concern for the interests of the public.
