Given a function (more generally, a measure) on a locally compact Abelian group, one can define the Toeplitz operators as certain integral transforms of functions on the dual group, where the kernel is the Fourier transform of the original function or measure. In the case of the unit circle, this corresponds to forming a matrix out of the Fourier coefficients in a particular way. We will study the asymptotic eigenvalue distributions of these Toeplitz operators.

Pseudodifferential operators on compact groups are discussed, with an emphasis on the conditions for which the theorem of Hille and Yosida holds. Some preliminary functional analysis is given including the notion of regularly dissipative operators and Pontrjagin duality. The dual group is described, especially that it is discrete. Some important inequalities, such as Young's inequality, are also stated. Generalised trigonometrical polynomials and generalised Sobolev spaces are defined on the compact group G. A finite exhaustion of the dual space is used to define pointwise convergence and to give a condition for which a generalised Sobolev space is continuously embedded in C(G) and compactly embedded into a larger Sobolev space. The thesis defines k-ellipticity, k-smoothing operators and the k-parametrix, and proves their relation to the compactness of the embedding. It is shown that k-ellipticity is characterised by an inequality of Garding type. Some examples of pseudodifferential operators with constant coefficients are given. Another inequality of Garding type is proved for pseudodifferential operators with variable coefficients, and the existence of a weak solution to (A(x,D) - lambda)u = f is given under certain conditions on the adjoint A*(x,D). A variational solution of B[ϕ,u] = (ϕ,f) is found, and we prove a Garding type inequality for the sesquilinear form.

This thesis is devoted to the study of operators on discrete structures. The operators are supposed to be self-adjoint and obey a certain translation invariance property. The discrete structures are given as Cayley graphs via finitely generated groups. Here, sofic groups and amenable groups are in the center of our considerations. Note that every finitely generated amenable group is sofic. We investigate the spectrum of a discrete self-adjoint operator by studying a sequence of finite dimensional analogues of these operators. In the setting of amenable groups we obtain these approximating operators by restricting the operator in question to finite subsets Qn , n ∈ N. These finite dimensional operators are self-adjoint and therefore admit a well-defined normalized eigenvalue counting function. The limit of the normalized eigenvalue counting functions when |Qn | → ∞ (if it exists) is called the integrated density of states (IDS). It is a distribution function of a probability measure encoding the distribution of the spectrum of the operator in question on the real axis. In this thesis, we prove the existence of the IDS in various geometric settings and for different types of operators. The models we consider include deterministic as well as random situations. Depending on the specific setting, we prove existence of the IDS as a weak limit of distribution functions or even as a uniform limit. Moreover, in certain situations we are able to express the IDS via a semi-explicit formula using the trace of the spectral projection of the original operator. This is sometimes referred to as the validity of the Pastur-Shubin trace formula. In the most general geometric setting we study, the operators are defined on Cayley graphs of sofic groups. Here we prove weak convergence of the eigenvalue counting functions and verify the validity of the Pastur-Shubin trace formula for random and non-random operators . These results apply to operators which not necessarily bounded or of finite hopping range. The methods are based on resolvent techniques. This theory is established without having an ergodic theorem for sofic groups at hand. Note that ergodic theory is the usual tool used in the proof of convergence results of this type. Specifying to operators on amenable groups we are able to prove stronger results. In the discrete case, we show that the IDS exists uniformly for a certain class of finite hopping range operators. This is obtained by using a Banach space-valued ergodic theorem. We show that this applies to eigenvalue counting functions, which implies their convergence with respect to the Banach space norm, in this case the supremum norm. Thus, the heart of this theory is the verification of the Banach space-valued ergodic theorem. Proceeding in two steps we first prove this result for so-called ST-amenable groups. Then, using results from the theory of ε-quasi tilings, we prove a version of the Banach space-valued ergodic theorem which is valid for all amenable groups. Focusing on random operators on amenable groups, we prove uniform existence of the IDS without the assumption that the operator needs to be of finite hopping range or bounded. Moreover, we verify the Pastur-Shubin trace formula. Here we present different techniques. First we show uniform convergence of the normalized eigenvalue counting functions adapting the technique of the Banach space-valued ergodic theorem from the deterministic setting. In a second approach we use weak convergence of the eigenvalue counting functions and additionally obtain control over the convergence at the jumps of the IDS. These ingredients are applied to verify uniform existence of the IDS. In both situations we employ results from the theory of large deviations, in order to deal with long-range interactions.

This study identified factors and variables of informal leadership in small groups with different gender composition (Men, women and mixed groups) and goal orientation (competition and cooperation). Behavioral dominance patterns (Information Sheet, pencil, decision sheet) and number of verbal interventions were compared to the main informal leadership factors identified in the groups. There were 24 participants (12 men and 12 women). Among the main variables and factors identified, there were some that had a higher possibility to appear than other. There was no significant difference of the factors and variables between women and men. Communication variables were more likely to be present in groups with the goal of cooperation as for the goal of competition. Guidance variables were more likely to be present in women groups than in men groups and mixed groups. There was a significant correlation between the factor’s Communication, Character and Guidance with the number of interventions and behavioral dominance patterns.

This dissertation advances our understanding of the structure of social relations between small groups and the larger organizations within which such groups are situated. Specifically, I examine structures of leadership and authority to gain an in-depth understanding of group organization in one nondenominational and one Southern Baptist megachurch. Methods include in-depth interviews with church clergy, staff, and group leaders; participant observation in groups and other church activities; and a written survey for group leaders. Using this combination of methods, I investigate how small groups are structured in terms of their connections to the megachurches within which they reside. I examine the extent to which the church staff provides oversight and exerts control over groups, and I connect variation on this dimension to how groups relate to their members and to the outside world.My findings include, first, that market metaphors permeate the organization of groups in these two megachurch organizations. The diffusion of ideas and practices from other institutional realms is notable in these two sites, and this may be true for megachurches more generally. Second, I argue that understanding strictness in religious groups is at least as much about the structure of relations between church leadership and membership as it is about beliefs. Third, small groups in megachurches look very much like small groups in American religion more generally, and church oversight may not make much difference in solving problems in small groups identified in previous research. Finally, I find that the level of oversight and control exerted by church leadership on the organization of groups may have a critical influence on the function of groups. Loose and tight connections appear to encourage a more outward and inward focus, respectively.Sociologists studying religious strictness or small groups in any setting should pay particular attention to the structure of relations connecting groups to the larger organizations within which they reside. Religious leaders interested in organizing groups of members should understand that the structure they create to connect with group leaders is at least as important as beliefs they teach leaders, in terms of influencing the focus of the groups.

For a finite group \(G\), the Hurwitz space \(H\)\(^i\)\(_r\)\(_,\)\(^n\)\(_g\) (\(G\)) is the space of genus \(g\) covers of the Riemann sphere with \(r\) branch points and the monodromy group \(G\). Let ε\(_r\)(\(G\)) = {(\(x\)\(_1\),...,\(x\)\(_r\)) : \(G\) = \(\langle\)\(x\)\(_1\),...,\(x\)\(_r\)\(\rangle\), Π\(^r\)\(_i\)\(_=\)\(_1\) \(x\)\(_i\) = 1, \(x\)\(_i\) ϵ \(G\)#, \(i\) = 1,...,\(r\)}. The connected components of \(H\)\(^i\)\(_r\)\(_,\)\(^n\)\(_g\)(\(G\)) are in bijection with braid orbits on ε\(_r\)(\(G\)). In this thesis we enumerate the connected components of \(H\)\(^i\)\(_r\)\(_,\)\(^n\)\(_g\)(\(G\)) in the cases where \(g\) \(\leq\) 2 and \(G\) is a primitive affine group. Our approach uses a combination of theoretical and computational tools. To handle the most computationally challenging cases we develop a new algorithm which we call the Projection-Fiber algorithm.

Let G be a complex semisimple Lie Group with parabolic subgroup P, so that G/P is a generalized flag manifold. An algebraic construction of invariant differential operators between sections of homogeneous bundles over such spaces is given and it is shown how this leads to the classification of all such operators. As an example of a process which naturally generates such operators, the algebraic Penrose transform between generalized flag manifolds is given and computed for several cases, extending standard results in Twistor Theory to higher dimensions. It is then shown how to adapt the homogeneous construction to manifolds with a certain class of tangent bundle structure, including conformal manifolds. This leads to a natural definition of invariant differential operators on such manifolds, and an algebraic method for their construction. A curved analogue of the Penrose transform is given.

The notion of a categorical semidirect product was introduced by Bourn and Janelidze as a generalization of the classical semidirect product in the category of groups. The main aim of this work is to study the general properties of semidirect products of groups with operators, describe them in various classical varieties of such algebraic structures and apply the results to homological algebra and related areas of modern algebra. The context in which the study is done is a semiabelian category (that is, a pointed, Barr-exact and Bourn-protomodular category). The main result in the thesis is the construction of the semidirect product in a variety -RLoop of right -loops as the product of underlying sets equipped with the -algebra structure. A variety of right -loops is a variety that is pointed, has a binary + (not necessarily associative or commutative) and a binary satisfying the identities 0 + x = x, x + 0 = x, (x + y) y = x and (x - y) + y = x. Thus, -RLoop is a generalization of the variety of -groups introduced by Higgins and the results obtained are valid for varieties of -loops. We also describe precrossed and crossed modules in the variety -RLoop. The theory of crossed modules developed is independent of that developed by Janelidze for crossed modules in an arbitrary semiabelian category and gives simplified explicit formulae for crossed modules in -RLoop. Finally, we mention that our constructions agree with the known ones in the familiar algebraic categories, specifically the categories of groups, rings and Lie algebras.

Reducing spacecraft ground system operations costs are a major goal in all missions. The Fast Auroral Snapshot (FAST) flight operations team at the NASA/Goddard Spacecraft Flight Center developed in-house scripts and procedures to automate monitoring of critical spacecraft functions. The initial staffing profile of 16x7 was reduced first to 8x5 and then to “lights out”. Operations functions became an offline review of system performance and the generation of future science plans for subsequent upload to the spacecraft. Lessons learned will be applied to the challenging Triana mission, where 24x7 contact with the spacecraft will be necessary at all times.

Corruption is a structural and a moral problem of modern societies. It undermines social development, democracy and people's wealth. The cost of corruption is about $1 trillion per year, and it is often paid by the poorest groups in society. To study corruption is, therefore, not only a scientific challenge but also a necessity in the search for social justice and in the context of improving quality of life. ( In fighting corruption, policy makers often have to decide whether to shape an in- tervention based on the individual or on the individual's perception of their environ- ment. Moreover, campaigns against corruption need to be tailored to the social context in which they will be implemented. Policies to be designed to counteract corruption can, therefore, benefit of a tool to differ social settings wit3respect to corruption. The current literature on corruption lacks a theoretical framework as well as tools for shedding light on the subject matter outlined above. The following research attempts to fill this. Qualitative and quantitative research evidence is used to identify social regularities brought about by corruption and, based on those observations, a set of social mechanisms are put forward. These are then used to design a model and a tool to gather first hand data. Finally, a new set of analytic techniques to grasp the degree to which groups affect individuals' decisions complete the methodology. Moreover, to show the strong empirical link between the model and the data gathering method, a data collection exercise with 16 participants is illustrated. This study proposes a new methodology for understanding how corruption emerges in small groups. More specifically, the extent to which group features affect individu- als' decisions as to whether or not to uphold corrupt practices is addressed in the context of limited public resources. The main result of this study is the development of the methodology itself, producing a set of values which are then interpreted to provide a measure of corruption. Such a measure quantifies the extent to which individuals' decisions are affected by their group. This contribution is particularly relevant for policy making, especially when it comes to deciding whether to design initiatives tailored to the individual or to the individuals perception of society.

This thesis focuses on the subject of varieties for modules for elementary abelian p-groups. Given a homogeneous polynomial over an algebraically closed field of char- acteristic 2 we will give constructions for modules of small dimension having that polynomial as variety. This is similar to an earlier construction given by Jon Carlson but our modules will in general be of considerably smaller dimension. We also investigate the connection between the variety of a module and its Loewy length. We show that working over an algebraically closed field of characteristic 2 with modules of Loewy length 2 allows us to find modules with any hypersurface as their variety. On the other hand we also demonstrate that in odd characteristic p, with modules of Loewy length p, the only possible varieties are finite unions of linear hypersurfaces.

This dissertation uses social movement theory to analyze the emergence, activities and development of subcultures and small groups. The manuscript is comprised of an Introduction followed by three journal articles and one book chapter.  The introduction discusses: 1) the concept of theoretical extension whereby a theory developed for one purpose is adapted to another; 2) it identifies the social movement theories used to analyze subcultures and small groups; 3) it describes the data used in the analyses included here. The data for this work derives from two distinct research projects conducted by the author between 2002 and 2012 and relies on multiple sources of qualitative data. Data collection techniques used include fieldwork, archival research, and secondary data. Paper I uses resource mobilization (RM) theory to analyze the origin, development, and function of White Power music in relation to the broader White Power Movement (WPM). The research identifies three roles played by White Power music: (1) recruit new adherents, (2) frame issues and ideology for the construction of collective identity, (3) obtain financial resources. Paper II gives an overview of the subculture of Freestyle BMX, discussing its origins and developments—both internationally as a wider subcultural phenomenon, and locally, through a three-year ethnographic case study of a subcultural BMX scene known as “Pro Town USA.” Paper III conceptualizes BMX as a social movement using RM theory to identify and explain three different forms of commercialization within this lifestyle sport in “Pro Town.” The work sheds light on the complex process of commercialization within lifestyle sports by identifying three distinct forms of commercialization: paraphernalia, movement, and mass market, and analyses different impacts that each had on the on the development of the local scene.  Findings reveal that lifestyle-sport insiders actively collaborate in each form of commercialization, especially movement commercialization which has the potential to build alternative lifestyle-sport institutions and resist adverse commercial influences. Paper IV refines the small group theory of collaborative circles by: (1) further clarifying its concepts and relationships, (2) integrating the concepts of flow and idioculture, and (3) introducing a more nuanced concept of resources from RM. The paper concludes by demonstrating that circle development was aided by specific locational, human, moral, and material resources as well as by complementary social-psychological characteristics of its members.

The results of a laboratory investigation into the behaviour of small groups of up to five granular columns, in soft clay, loaded by various foundation configurations under rapid undrained conditions is presented. Columns with a constant layer length to diameter ratio in both floating and end-bearing conditions are considered. Electronic instrumentation was developed to record boundary stresses and displacements and radiographic techniques were employed to measure internal displacements and strains in the columns and clay. Extensive use of interactive mainframe and mini computers was made in collecting, storing and processing the laboratory data. The improvement in bearing capacity and reduction in settlement was found to be strongly dependent on the relative column and clay areas in contact with a foundation. The column end-bearing condition was also a contributory factor. The mechanism of column and clay deformation was observed as being dependent on the boundary conditions. Column yield occurred as a general shear failure or a local shear failure depending on the relative sizes of the clay and column areas. Laboratory results showed that direct analogy with conventional piles or pile groups cannot be made. An empirical relationship for estimating the improvement in bearing capacity and settlement is proposed.

This thesis is focussed on the role differentiationhypothesis as it relates to small groups (Bales, 1958). The hypothesis is systematically examined, both conceptually and empirically, in the light of the Equilibrium Hypothesis (Bales, 1953) and the Negotiated Order Theory of leadership (e.g. Hosking, 1988). Chapter 1 sketches in a context for the research,which was stimulated by attempts during the 60s and 70s to organise small groups without leaders (the leaderless group, based on isocratic principles). Chapter 2 gives a conceptual and developmental overview of Bales' work, concentrating on the Equilibrium Hypothesis. It is argued that Bales' conceptual approach, if developed, can potentially integrate the disparate small groups and leadership literatures. Chapters 3 and 4 examine the concepts `group', `leader' and `leadership' in terms of the Negotiated Order perspective. In chapter 3 it is argued that two aspects of the concept group need to be taken separately into account; physical attributes and social psychological aspects (the metaphysical glue). It is further argued that a collection of people becomes a group only when they begin to establish a shared sense of social order. In chapter 4 it is argued that leadership is best viewed as a process of negotiation between those who influence and those who are influenced, in the context of shared values about means and ends. It is further argued that leadership is the process by which a shared sense of social order is established and maintained, thus linking the concepts `leadership' and `group' in a single formulation. The correspondences with Bales' approach are discussed at the end of the chapter. Chapters 5 to 8 present a detailed critical description and evaluation of the empirical work which claims to show role differentiation or test the hypothesis, both Bales original work and subsequent studies. It is argued here, that the measurement and analytical procedures adopted by Bales and others, in particular the use of simple means as summaries of group structures, are fundamentally flawed, and that role differentiation in relation to particular identifiable groups has not been demonstrated clearly anywhere in the literature. Chapters 9 to 13 present the empirical work conducted for the thesis. 18 small groups are examined systematically for evidence of role differentiation using an approach based on early sociometry (Moreno, 1934). The results suggest that role differentiation, as described by Bales, does not occur as often as is implied in the literature, and not equivocally in any case. In particular structures derived from Liking are typically distributed or weak. This suggests that one of Bales' principal findings, that Liking varies independently of his other main dimensions, is the product of statistical artifact. Chapter 14 presents a general summary of results and presents some considerations about future research.

Small groups are integral for many activities in the foreign language classroom and their pedagogical importance is well established. Despite the widespread use of groups in foreign language education, there is a dearth of research investigating group processes and the impact of emergent leaders within these groups. This mixed-methods, longitudinal study was designed to first establish the presence of emergent leaders within an SLA context, and then to investigate the factors influencing who will emerge as the leader, and the impact they have on the views and performance of the group. First-year students majoring in science at a private university in western Japan were placed into three English Communication classes depending on their major within the school, and further randomly assigned to small groups of three to four people within each class. Students worked together in these groups for the first semester spanning 14 weeks and were required to take part in group presentations and group discussions. Measures of aural and general English ability, English communication self-efficacy, and the Big Five dimensions of personality were used to predict who would emerge as leaders within each group, and group and individual change was tracked using measures of self- and collective-efficacy. Participant and video observation, and interview data were used to provide rich description of the intra-group processes. In the second semester the students were allowed to self-select their groups, which were then fixed for the 14-week course. The first finding of the study was that leaders emerged in the small groups in this context, and proficiency in English was found to be the only consistent predictor of group leader emergence, with extroversion predicting initial perceptions of leadership only. The second finding of the study was that individuals' perceived leadership was relatively stable when in the same group, but that when the group makeup was changed there were large differences in the perceived leadership scores, suggesting that leadership behavior depends on the group in which students are in, and that group makeup influences individual student behavior. The third finding was that different types of leader were found to exist, with visible leaders who were easily identified by the teacher, and invisible leaders who were recognized by group members to be leader, but not clear to the teacher. The fourth finding was that collective-efficacy was existed as a group-level construct in this context, and growth models showed that self-efficacy increased for students in both the first and second semesters, and that the group experiences in the first semester seemed to influence rates of change in self-efficacy in the second semester, suggesting that the products of previous group experiences carry into subsequent group work and affect attitudes and behavior. The fifth finding was that students select group members based on friendship, but that students had mixed preferences with regard the choice between random group formation and self-selection into groups. Students almost universally felt that changing group members at regular intervals of several weeks was beneficial. Overall the study highlighted the importance of group makeup, and particularly leadership in this context, and showed that behavior in the language classroom was heavily influenced by group members.

Simple environmental features can shape complex behavior. Identifying key aspects of the environment (e.g., temperature, structure, toxins) that lead to widespread consequences is of central importance in a changing world. The primary objective of my dissertation is to investigate how relatively simple aspects of the environment can influence small groups of animals in profound and complex ways. In the first three chapters, I report on experiments showing how small changes in the environment can affect the expression of behavior at different points in development and can have important physiological consequences for litters of mouse pups. I then report on two sets of experiments showing how subtle changes in the environment can dramatically affect spacing patterns and social dynamics of small groups of adult zebrafish. Together, my results emphasize the ways that subtle changes in the environment can have profound impacts on individuals and small groups. In both lines of work, I have found that a more accurate characterization of the phenomena, infant rodent development and zebrafish social behavior, requires the use of individual and group measures and that temperature, density, and pollutants can have a powerful effect on group responses. These results are important because they show that the physical environment can have profound effects on the phenotype, and that with a changing physical environment or anthropogenic change, dramatic differences may be observed in the behavior of groups.

In the first part, we study amalgams of relatively hyperbolic groups and also therelatively quasiconvex subgroups of such amalgams. We prove relative hyperbolicityfor a group that splits as a finite graph of relatively hyperbolic groups with parabolicedge groups; this generalizes a result proved independently by Dahmani, Osin andAlibegovic. More generally, we prove a combination theorem for a group that splitsas a finite graph of relatively hyperbolic groups with total, almost malnormal andrelative quasiconvex edge groups. Moreover, we provide a criterion for detectingquasiconvexity of subgroups in relatively hyperbolic groups that split as above. As anapplication, we show local relative quasiconvexity of any f.g. group that is hyperbolicrelative to Noetherian subgroups and has a small-hierarchy. Studying free subgroupsof relatively hyperbolic groups, we reprove the existence of a malnormal, relativelyquasiconvex, rank 2 free subgroup F in a non-elementary relatively hyperbolic groupG. Using this result and with the aid of a variation on a result of Arzhantseva, weshow that if G is also torsion-free then "generically" any subgroup of F is aparabolic,malnormal in G and quasiconvex relative to P and therefore hyperbolically embedded.As an application, generalizing a result of I. Kapovich, we prove that for any f.g.,non-elementary, torsion-free group G that is hyperbolic relative to P, there exists agroup G∗ containing G such that G∗ is hyperbolic relative to P and G is not relativelyquasiconvex in G∗ .In the second part, we investigate the existence of F2 × F2 in the non-metric small-cancellation groups. We show that a C(6)-T(3) small-cancellation group cannotcontain a subgroup isomorphic to F2 × F2 . The analogous result is also proven in theC(3)-T(6) case.
Dans la premiere partie, nous etudions les amalgames de groupes relativement hyperboliques et egalement les sous-groupes relativement quasiconvexes de ces amalgames. Nous prouvons l'hyperbolicie relative pour un groupe qui se separe comme un graphe fini de groupes relativement hyperboliques avec des groupes d'aretes paraboliques, ce qui generalise un resultat prouve independamment par Dahmani,Osin et Alibegovic. Nous l'etendons au cas ou les groupes d'aretes sont totalaux, malnormal et relativement quasiconvexes. En outre, nous fournissons un critere de detection de quasiconvexite relative des sous-groupes dans les groupes hyperboliques qui divisent. Comme application, nous montrons la quasiconvexite locale relative d'un groupe qui est relativement hyperbolique a certains sous-groupes noetheriens et qui a une petite hierarchie. Nous etudions egalement les sous-groupes libres de groupes relativement hyperboliques, et reprouvons l'existence d'un sous-groupe libre, malnormal, relativement quasiconvexe F2 dans un groupe non- elementaire relativement hyperbolique G. En combinant ce resultat avec une variation sur un theoremede Arzhantseva, nous montrons que si G est aussi sans-torsion, "generiquement" tout sous-groupe de F2 est aparabolique, malnormal dans G et quasiconvexe par rapport a P. Comme application, nous montrons que pour tout groupe G non-elementaire, sans-torsion, qui est hyperbolique par rapport a P, il existe un groupe G∗ contenant G tel que G∗ est hyperbolique par rapport a P et G n'est pas quasiconvexe dans G∗. Dans la deuxieme partie, nous etudions l'existence de sous-groupe F2 × F2 dans desgroupes a petite simplification. Nous montrons que les groupes C(6) ne peuvent pas contenir un sous-groupe isomorphe a F2 × F2 . Le resultat analogue est egalement prouve dans le dossier C(3)-T(6) affaire.
