Multimembership and Identity in Writing Centers and in Industry: Examining the Work of Reconciliation in the Michigan Tech Multiliteracies Center and at Kimberly-Clark Corporation

Writing center scholarship and practice have approached how issues of identity influence communication but have not fully considered ways of making identity a key feature of writing center research or practice. This dissertation suggests a new way to view identity -- through an experience of "multimembership" or the consideration that each identity is constructed based on the numerous community memberships that make up that identity. Etienne Wenger (1998) proposes that a fully formed identity is ultimately impossible, but it is through the work of reconciling memberships that important individual and community transformations can occur. Since Wenger also argues that reconciliation "is the most significant challenge" for those moving into new communities of practice (or, "engage in a process of collective learning in a shared domain of human endeavor" (4)), yet this challenge often remains tacit, this dissertation examines and makes explicit how this important work is done at two different research sites - a university writing center (the Michigan Tech Multiliteracies Center) and at a multinational corporation (Kimberly-Clark Corporation). Drawing extensively on qualitative ethnographic methods including interview transcriptions, observations, and case studies, as well as work from scholars in writing center studies (Grimm, Denney, Severino), literacy studies (New London Group, Street, Gee), composition (Horner and Trimbur, Canagarajah, Lu), rhetoric (Crowley), and identity studies (Anzaldua, Pratt), I argue that, based on evidence from the two sites, writing centers need to educate tutors to not only take identity into consideration, but to also make individuals' reconciliation work more visible, as it will continue once students and tutors leave the university. Further, as my research at the Michigan Tech Multiliteracies Center and Kimberly-Clark will show, communities can (and should) change their practices in ways that account for reconciliation work as identity, communication, and learning are inextricably bound up with one another.

Privacy concerns and identity in online social networks

Driven by privacy-related fears, users of Online Social Networks may start to reduce their network activities. This trend can have a negative impact on network sustainability and its business value. Nevertheless, very little is understood about the privacy-related concerns of users and the impact of those concerns on identity performance. To close this gap, we take a systematic view of user privacy concerns on such platforms. Based on insights from focus groups and an empirical study with 210 subjects, we find that (i) Organizational Threats and (ii) Social Threats stemming from the user environment constitute two underlying dimensions of the construct “Privacy Concerns in Online Social Networks”. Using a Structural Equation Model, we examine the impact of the identified dimensions of concern on the Amount, Honesty, and Conscious Control of individual self-disclosure on these sites. We find that users tend to reduce the Amount of information disclosed as a response to their concerns regarding Organizational Threats. Additionally, users become more conscious about the information they reveal as a result of Social Threats. Network providers may want to develop specific mechanisms to alleviate identified user concerns and thereby ensure network sustainability.

The Function of Norms and Values in the Construction of Social Identity in Groups who experienced intergroup Conflicts

I present my explorative research about conflict and social identity. The Social Identity Approach of Henri Tajfel and John Turner is used as theoretical frame in the study. The main question is how the construction of social identity of group members is influenced by an inter-group conflict. The research project consists of two parts: 1. An empirical study conducted with qualitative research methods to investigate a today’s congregation of the Swiss reformed Church who experienced a conflict about twenty years ago. This conflict ended by the separation of a sub-group from the congregations. This group forms an independent community today. Members of both congregations where interviewed about the meaning which membership has for them and about their interpretation of the conflict. 2. An analysis of the Gospel of Matthew with questions who where developed out of the empirical study and the Social Identity Approach to better understand the separation conflict between the Matthean community and the synagogue.

{\it Hox\/} genes and specification of regional identity in the axial skeleton: Analysis of the individual and combined mutant phenotypes of the paralogous group 4 murine {\it Hox\/} genes; {\it hoxa\/}-4, {\it hoxb\/}-4 and {\it hoxd\/}-4

The Hox gene products are transcription factors involved in specifying regional identity along the anteroposterior body axis. In Drosophila, where these genes are known as HOM-C (Homeotic-complex) genes and where they have been most extensively studied, they are expressed in restricted domains along the anteroposterior axis with different anterior limits. Genetic analysis of a large number of gain- and loss-of-function alleles of these genes has revealed that these genes are important in specifying segmental identity at their anterior limits of expression. Furthermore, there is a functional dominance of posterior genes over anterior genes, such that posterior genes can dominantly specify their developmental programs in spite of the expression of more anterior genes in the same segment. In the mouse, there are four clusters of HOM-C genes, called Hox genes. Thus, there may be up to four genes, called paralogs, that are more highly homologous to each other and to their Drosophila homolog than they are to the other mouse Hox genes. The single mutants for two paralogous genes, hoxa-4 and hoxd-4, presented in this dissertation, are similar to several other mouse Hox mutants in that they show partial, incompletely penetrant homeotic transformations of vertebrae at their anterior limit of expression. These mutants were then bred with hoxb-4 mutants (Ramirez-Solis, et al. 1993) to generate the three possible double mutant combinations as well as the triple mutant. The skeletal phenotypes of these group 4 Hox compound mutants displayed clear alterations in regional identity, such that a nearly complete transformation towards the morphology of the first cervical vertebra occurs. These results suggest a certain degree of functional redundancy among paralogous genes in specifying regional identity. Furthermore, there was a remarkable dose-dependent increase in the number of vertebrae transformed to a first cervical vertebra identity, including the second through the fifth cervical vertebrae in the triple mutant. Thus, these genes are required in a larger anteroposterior domain than is revealed by the single mutant phenotypes alone, such that multiple mutations in these genes result in transformations of vertebrae that are not at their anterior limit of expression. ^
