The purpose of this study lies in its attempt to contribute to the understanding of leadership in small groups of boys in a conceptual framework that considers leadership as a dynamic interacting process rather than the summation of individual traits.

The main objective was to determine the effect of film-mediated models on the frequency of a specific quality of verbal responses which have been found to be indicative of high- levels of therapeutic movement in group counseling. Secondly, this study examined the effect of models on selected attitudes of group counseling participants toward interpersonal interactions reflective of the intense interaction involved in therapeutic movement in group counseling.

The specific purposes of this study were to measure the changes in self-insight, dogmatic attitudes, Dominance and Change variables on the Edwards Personal Preference Schedule, and discrimination variables on the Carkhuff Discrimination Scale subsequent to personal group counseling experiences and their relationships to other measures believed to be indicative of counselor effectiveness.

In this dissertation, we describe the automorphism groups for the strong Bruhat orders A_n-1, B_n, and D_n. In particular, the automorphism group of A_n-1 for n ≥ 3 is isomorphic to the dihedral group of order eight, D_4; the automorphism group of B_n for n ≥ 3 is isomorphic to C_2 x C_2 where C_2 is the cyclic group of order two; the automorphism group of D_n for n > 5 and n even is isomorphic to C_2 x C_2 x C_2; and the automorphism group of D_n for n ≥ 5 and n odd is isomorphic to the dihedral group D_4.

An abundance of information regarding the structure of a finite group can be obtained by studying its irreducible characters. Of particular interest are monomial characters – those induced from a linear character of some subgroup – since Brauer has shown that any irreducible character of a group can be written as an integral linear combination of monomial characters. Our primary focus is the class of M-groups, those groups all of whose irreducible characters are monomial. A classical theorem of Taketa asserts that an M-group is necessarily solvable, and Dade proved that every solvable group can be embedded as a subgroup of an M-group. After discussing results related to M-groups, we will construct explicit families of solvable groups that cannot be embedded as subnormal subgroups of any M-group. We also discuss groups possessing a unique non-monomial irreducible character, and prove that such a group cannot be simple.

Both the Council for Accreditation of Counseling and Related Education Programs (CACREP) and the Association for Specialists in Group Work (ASGW) require counselor education programs to provide experiential training to group workers (CACREP, 2009; ASGW, 2000). However, no specific models are given to counselor educators to implement the experiential component. Only two research studies have examined the overall structure and type of instructor involvement commonly used in counselor training programs (Anderson & Price, 2001; Merta, Wolfgang, & McNeil, 1993). In addition, researchers have documented ethical concerns in the use of experiential training methods (Davenport, 2004; Furr & Barret, 2000; Riva & Korinek, 2004) including the role of dual relationships, confidentiality, and competency. Student experience of the experiential training is impacted by both the structure of the experiential group and the ethical pitfalls associated with each (Goodrich, 2008). Thus, the purpose of this study was to determine the current models of group work and how the structure of these models impacted student attitudes toward ethical concerns of dual relationships, confidentiality, and competency and overall student experience. Members of the American Counseling Association (ACA) who had graduated with their master's degree in the past five years were asked to respond to the Survey of Student Attitudes and Instructor Participation in Experiential Groups online survey. The findings of this study suggested that the most common group work training model is to have a full-time faculty member both instruct the group work course and facilitate the experiential group. In addition, concern over ethical issues was found to be an important component in student's comfort level and belief that the experiential group was instrumental in their development as a group counselor. These results do not support the findings of Anderson and Price (2001) which suggested a growing trend of group work instructors not being both the facilitator of the experiential group and the instructor of the course. However, the findings do support previous research which indicated that ethical concerns do negatively impact student involvement in the experiential group (Davenport, 2004; Hall, Hall, Harris, Hay, Biddulph, & Duffy, 1999).

The Polycomb group (Pc-G) and trithorax group (trx-G) genes play crucial roles in development by regulating expression of homeotic and other genes that control cell fate. Both groups catalyse modifications in chromatin, including histone methylation, leading to epigenetic changes in gene activity. The trx-G antagonises the function of Pc-G genes by activating Pc-G target genes, and consequently trx-G mutants suppress Pc-G mutants. The trx-G genes are relatively poorly characterised in plants. We identified a novel trx-G candidate SUPRESSOR OF POLYCOMB 12 (SOP12) by a genetic screen for suppressors of mutants for the Arabidopsis Pc-G gene CURLY LEAF (CLF). Thus sop12 mutations have no discernible phenotype in wild type backgrounds but partially suppress the leaf curling and early flowering phenotypes of clf mutants. Molecular cloning shows that SOP12 encodes a Harbinger transposase nuclease-like protein which is conserved in green plants, although key residues required for the catalytic activity of the nuclease domain are not conserved. In sop12 clf double mutants, many CLF target genes are down-regulated relative to clf mutant, which suggests SOP12 is a general activator of Pc-G target genes instead of a target of CLF or a late flowering suppressor. The CLF gene encodes an H3K27me3 histone methyltransferase, however chromatin immunoprecipitation (ChIP) analysis indicates that SOP12 does not antagonise Pc-G by removing H3K27me3 methylation, which is consistent with the fact that sop12 suppresses mutants for another Pc-G gene, LIKE HETEROCHROMATIN PROTEIN 1 (LHP1), which is not involved in H3K27me3 deposition. . Rather, genetic analysis shows that sop12 enhances the phenotype of mutants of EARLY FLOWERING IN SHORT DAYS (EFS), a trx-G gene involved in deposition of H3K36me3, and of ULTRAPETALA 1 (ULT1), a plant specific trx-G gene. The enhancement indicates SOP12 may act together with ULT or EFS proteins, or at least regulate the same targets in synergistic ways. For example, SOP12 activates AP3 expression, a role which overlaps with EFS. Yeast two hybrid screening and imunoprecipitation followed by Mass spectrometry were performed to identify numerous potential SOP12 interacting proteins but await further validation. One protein (SUP1) identified through yeast two hybrid screens was independently identified by another group as a Pc-G suppressor, suggesting that SOP12 and SUP1 may act in a common complex to regulate Pc-G targets. Collectively, my data suggests that SOP12 represents a domestic transposase that has acquired a role as a novel, plant specific trx-G members.

Atheists are some of the least liked people in the world. Previous research has demonstrated that in most stigmatized groups, increased prevalence of the group increases prejudice towards the group. However, the opposite has been found with atheists- increased perceived prevalence decreases prejudice towards atheists. One post-hoc explanation provided for this difference is that since atheists are easily concealable and unorganized as a group, their greater prevalence may not be perceived as a threat. In the present thesis, I 1) attempted to replicate the existing finding that perceived increased prevalence would increase trust towards atheists and 2) directly tested the hypothesis that if atheist groups are presented as collectively powerful and coherent, increased prevalence will no longer decrease anti-atheist prejudice. I did not find support for the hypothesis that prevalence increases atheist trust, nor did I find support for my hypotheses that power and cohesion would manipulate distrust. Atheist prejudice is still pervasive, however, prejudice against atheists may be changing.

This thesis explores the quality and sustainability of facilitated co-operative processes in organisations, and the difficulties and opportunities associated with this way of working. Three complementary research methods have been used: a survey, an Internet dialogue and a co-operative inquiry of facilitators, managers and academics. The survey revealed that facilitators have diverse and sometimes contradictory approaches to their organisational work, co-operative processes are not easy to sustain within hierarchical organisations, and that facilitator ethics need clarification. The development of a Statement of Values and Code of Ethics by the International Association of Facilitators formed the content for the Internet dialogue part of this research. The co-operative inquiry highlighted that sustainable co-operation depends on embodied whole people connecting with love and compassion, and with the commitment and courage to speak their own truth and deeply engage with the collective wisdom of the group. It is shown that co-operative organisational forms, methods, processes, values and ethics are only part of what is needed to support co-operative endeavour. Underpinning all of these are ways of being that are learnt through modelling and mutually supportive interactions between persons in relationship. These ways of being need to be transmitted along with conceptual frameworks, processes and methods for ‘co-operacy’ to be sustainable in groups and organisations / Doctor of Philosophy (PhD)
