This mixed-methods study consisted of two phases. First, interviews were conducted with ROTC instructors responsible for organizational socialization of newcomers to the U.S. Army and U.S. Air Force. This data shaped surveys given to organizational newcomers in phase II, which measured organizational culture and cognitive leadership schemas. It was hypothesized that implicit leadership theories (ILTs) would reflect respective organizational cultures. Although this was supported in the qualitative results from Phase I, it was not supported in the quantitative results from Phase II. However, analyses showed that leadership is still perceived as a masculine role in both the U.S. Army and U.S. Air Force, as was hypothesized. It was also hypothesized that leaders in line occupations would be seen as better leaders than leaders in staff occupations. This was supported for the Air Force sample, but not the Army sample. During the interviews, ROTC instructors asserted that male and female leaders were equally capable, and that line and staff leaders were equally capable. However, questioning revealed that organizational stereotypes still defined the quintessential leader as a male in a line occupation, although females had more opportunities to fill those key occupations in the Air Force than in the Army, at the time of this study. This discrepancy, along with the discrepancies in results between the qualitative and quantitative data, indicate that organizational culture has perhaps changed at the levels of visible artifacts and espoused values with respect to diversity, but has not yet changed at the fundamental level of basic assumptions.

Повний текст джерелаThe question of whether cinema is democratic is a vast one, which requires research limitations of time and place to actually find an answer for. In this study, the place will be the United States, because nowhere else is the industry of cinema so powerful and generates more elements of popular culture; where also the country is considered to be democratic and practicing freedom of speech. The time will be the period following 11th September 2001: a date after which American politics has been chaotic both inside and outside the country, consequently producing a very controversial subject matter to debate in films.
However, the question still remains huge as the answer might differentiate according to the varying scope different types of cinema productions may hold. Accordingly, we will limit our focus within the field of political alternative films; and apply and seek to verify Jürgen Habermas’ theory of the public sphere in analysing their content to reach inferences on democracy. Afterwards, enlarging our perspective to the American cinema industry by and large, we will argue that the economic value of a film and the subject it deals with undermine the democratic ideals of equal representation the public sphere carries, as capitalism enters the scene. Some other dilemmas will emerge on this path: are movies being imposed by a dominant class in order to make the audience passive towards their environment? Or is it the audience, the people themselves, who create the aspects of popular culture in cinema?
Finally, we are to put the first question in other terms: does cinema socially and democratically represent its viewers’ ideology? In the limit of our empirical means, giving responses to those questions will be the heart of this thesis.

Повний текст джерелаAim: Culture exists in every organization, whether you actively work with it or not. Old cultures often carry traditions and are hard to change. The purpose of this thesis is to describe Gävle Galvan from an organizational point of view and also to investigate the culture from a gender point of view.
Method: The thesis is written with a qualitative and narrative approach. I have taken part in three person’s stories through interviews and thereby created picture of their everyday work on Gävle Galvan. It’s hard to describe a company’s culture and I have, with help from the stories and my own observations, tried to give an as balanced picture as possible. The interviews and my observations, together with organizational theoretical concepts, create my story of the company.
Conclusions: This study is confirmed by Schein’s theory; it’s difficult to change old behaviours and traditions, what Schein calls assumptions. Gävle Galvan characterizes by its history and how it’s always been. What once was created has been well kept and led to an assumption. The culture has a couple of culture carrier who have been in the organization for many decades. These persons are often respected because they have a long experience of the profession and they will not accept new co-workers that don’t share their norms and values. The forced habits make it hard for Gävle Galvan to adjust their activities in terms of equality between the sexes. Traditions contribute to generalize the female sex and the profit of having both women and men in an organization doesn’t come thru.
Syfte: Kultur är något som finns i organisationer, oavsett om ett aktivt kulturarbete sker eller inte. Äldre kulturer bär ofta med sig traditioner och har en djupt rotad kultur som är svår att förändra. Syftet med uppsatsen är att beskriva Gävle Galvan ur organisationsteoretiska begrepp samt se på organisationen och dess kultur ur ett genusperspektiv.
Metod: Uppsatsen är skriven ur en kvalitativ, berättande ansats. Jag har tagit del av tre personers berättelser genom att ställa intervjufrågor och därmed fått en bild av deras vardag på Gävle Galvan. Det är svårt att beskriva ett företags kultur och jag har med hjälp av dessa tre personer och mina egna iakttagelser på plats försökt få en nyanserad bild av Gävle Galvan. Intervjuberättelserna och iakttagelser blir med hjälp organisationsteoretiska begrepp min berättelse om företaget.
Slutsats: Studien bekräftas av Scheins teori, det är svårt att ändra djupt rotade beteende och traditioner alltså det Schein kallar antaganden. Gävle Galvan präglas av dess historia och hur det alltid har varit. Det som en gång skapats har vårdats och sjunkit in till förgivet-tagna-antagande. Kulturen har några kulturbärare som arbetat i organisationen i många decennier, dessa personer är ofta respekterade eftersom de har lång erfarenhet av yrket och stöter bort människor som inte delar samma normer och värderingar. Dessa vana mönster gör de även svårt för Gävle Galvan att anpassa verksamheten ur ett jämställt perspektiv. Traditionerna bidrar till en generalisering av kvinnor och vinsterna med en jämställd arbetsplats lyfts inte fram.

Doctoral thesis, Linköpings universitet, Institutionen för kultur och kommunikation, 2009. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-51874.
Повний текст джерелаInteraktioner utformas och gestaltas olika från kultur till kultur. Avhandlingen fokuserar på denna aspekt och behandlar först ur ett teoretiskt perspektiv hur detta fenomen kan beskrivas. Med en tvärvetenskaplig ansats inom ramen av den s.k. interkulturella kommunikationsforskningen (cross-cultural communication) kombineras kulturanalytiska med lingvistiska och samtalsanalytiska teorier och metoder. Ett semiotiskt koncept utarbetas med hjälp av vilka olika kulturspecifika interaktionsstilar kan beskrivas. Det semiotiska fältet som koncipierats kallas för Einbettungskultur (’inbäddningskulturen’). I den andra delen används och prövas detta koncept. Med hjälp av ett flertal videoinspelade lunchsamtal i Sverige och Tyskland analyseras konkreta exempel på kommunikativ praxis och deras kulturella mönster i jämförbara interaktionssituationer. Det beskrivs hur den kulturspecifika interaktionsstilen vid lunchen bland svenska arbetskollegor kan skilja sig från det tyskspråkiga sättet att gestalta samma interaktionstyp. Inspelningssituationen problematiseras och kamerans roll i interaktionen diskuteras. Eftersom analyserna huvudsakligen baseras på samtal mellan män tas genusperspektivet upp. Vid sidan av själva samtalen analyseras även scenariot, tidsaspekten och ritualiseringen av interaktionen vid bordet som tre aspekter av inbäddningskulturen som tillsammans bidrar till en kulturspecifik interaktionsstil. Resultaten av den kulturella analysen som tar sin utgångspunkt i en konkret och jämförbar interaktionssituation i olika kulturer relateras avslutningsvis till andra, icke-interaktionsbaserade analyser inom den interkulturella kommunikationsforskningen och nationalkulturella beskrivningar problematiseras.
Ramirez, Andrea R. "Acculturation, Cultural Intelligence, and Implicit Leadership Theories." Thesis, Regent University, 2014. http://pqdtopen.proquest.com/#viewpdf?dispub=3583446.
Повний текст джерелаThe Global Leadership and Organizational Behavior Effectiveness (GLOBE) study contributed a wealth of knowledge regarding the differences across national/societal cultures. However, it did not attempt to measure the potential variations in implicit leadership theories (ILTs; leadership prototypes) that could occur due to individuals being influenced by more than one national culture within countries, such as bicultural individuals. Variations found within a country can be described by their extent of acculturation or adoption of one or more cultural influences. The extent of a person’s acculturation may predict individual ILTs, which are the patterns of attributes that bicultural persons associate with good leaders. In addition, the extent of a person’s cultural intelligence (CQ) may interact with acculturation in impacting ILTs because CQ influences a person’s ability to understand and adjust mental modes to cultural norm. This study explored the relationships among acculturation, CQ, and ILTs in a sample of respondents from Mexican descent living in the United States. The results of the study provide a better understanding of how variations in national culture impact ILTs. In addition, the findings suggest interpretation of cultural dimensions is complex. Significant findings include (a) differences across acculturation levels regarding expectation for a leader to be characterized by the ILT dimensions of sensitivity and tyranny; (b) very Mexican-oriented individuals (acculturation Level 1) showing more expectation for a leader to be characterized as well-dressed, well-groomed, compassionate, understanding, sympathetic, and sensitive and less expectation for a leader to be domineering and demanding than Anglo-oriented individuals (acculturation Level 3), acculturation serving as a predictor of metacognitive CQ; (c) acculturation and metacogntive CQ clearly interacting thus complicating the picture of cultural effects occurring during adjustments to a new cultural setting; and (d) metacognitive CQ serving as a partial mediator between acculturation level and the ILT dimension of sensitivity.

Повний текст джерелаThis work deals with three quantum field theories on spaces with noncommuting position operators. Noncommutative models occur in the study of string theories and quantum gravity. They usually elude treatment beyond the perturbative level. Due to the technique of dimensional reduction, however, we are able to investigate these theories nonperturbatively. This entails translating the action functionals into a matrix language, which is suitable for numerical simulations. First we explore a scalar model on a noncommutative plane. We investigate the continuum limit at fixed noncommutativity, which is known as the double scaling limit. Here we focus especially on the fate of the striped phase, a phase peculiar to the noncommutative version of the regularized scalar model. We find no evidence for its existence in the double scaling limit. Next we examine the U(1) gauge theory on a four-dimensional spacetime, where two spatial directions are noncommutative. We examine the phase structure and find a new phase with a spontaneously broken translation symmetry. In addition we demonstrate the existence of a finite double scaling limit which confirms the renormalizability of the theory. Furthermore we investigate the dispersion relation of the photon. In the weak coupling phase our results are consistent with an infrared instability predicted by perturbation theory. If the translational symmetry is broken, however, we find a dispersion relation corresponding to a massless particle. Finally, we investigate a supersymmetric theory on the fuzzy sphere, which features scalar neutral bosons and Majorana fermions. The supersymmetry is exact in the limit of infinitely large matrices. We investigate the phase structure of the model and find three distinct phases. Summarizing, we study noncommutative field theories beyond perturbation theory. Moreover, we simulate a supersymmetric theory on the fuzzy sphere, which might provide an alternative to attempted lattice formulations.

Повний текст джерелаIn this paper we study the pecking order and tradeoff theories of capital structure on a sample of 121 Swedish, non-financial, listed firms over the period between 2000 - 2009. We find that the Swedish firms’ financing behavior appears to have features consistent with the predictions of both theories. The evidence shows a preference for a financing behavior consistent with the tradeoff theory for the whole sample and for a sample of small firms, whereas large firms appear to follow a pecking order on their financing decisions. We show that under sufficient conditions both theories might be seen as “reconciled” and not mutually exclusive, and we find evidence for the large firms of our sample consistent with this notion.

Повний текст джерелаIn this dissertation, we present work towards characterizing various conformal and nearly conformal quantum field theories nonperturbatively using a combination of numerical and analytical techniques. A key area of interest is the conformal window of four dimensional gauge theories with Dirac fermions and its potential applicability to beyond the standard model physics.
In the first chapter, we review some of the history of models of composite Higgs scenarios in order to motivate the study of gauge theories near the conformal window. In the second chapter we review lattice studies of a specific theory, SU(3) gauge theory with eight flavors of Dirac fermions in the fundamental representation of the gauge group. We place a particular emphasis on the light flavor-singlet scalar state appearing in the spectrum of this model and its possible role as a composite Higgs boson. We advocate an approach to characterizing nearly conformal gauge theories in which lattice calculations are used to identify the best low energy effective field theory (EFT) description of such nearly conformal gauge theories, and the lattice and EFT are then used as complementary tools to classify the generic features of the low energy physics in these theories. We present new results for maximal isospin ππ → ππ scattering on the lattice computed using Lüscher's finite volume method. This scattering study is intended to provide further data for constraining the possible EFT descriptions of nearly conformal gauge theory. In Chapter 3, we review the historical development of chiral effective theory from current algebra methods up through the chiral Lagrangian and modern effective field theory techniques. We present a new EFT framework based on the linear sigma model for describing the low lying states of nearly conformal gauge theories. We place a particular emphasis on the chiral breaking potential and the power counting of the spurion field.
In Chapter 4, we report on a new formulation of lattice quantum field theory suited for studying conformal field theories (CFTs) nonperturbatively in radial quantization. We demonstrate that this method is not only applicable to CFTs, but more generally to formulating a lattice regularization for quantum field theory on an arbitrary smooth Riemann manifold. The general procedure, which we refer to as quantum finite elements (QFE), is reviewed for scalar fields. Chapter 5 details explicit examples of numerical studies of lattice quantum field theories on curved Riemann manifolds using the QFE method. We discuss the spectral properties of the finite element Laplacian on the 2-sphere. Then we present a study of interacting scalar field theory on the 2-sphere and show that at criticality it is in close agreement with the exact c = 1/2 minimal Ising CFT to high precision. We also investigate interacting scalar field theory on [special characters omitted] x [special characters omitted]2, and we report significant progress towards studying the 3D Ising conformal fixed point in radial quantization with the QFE method. In the near future, we hope for the QFE method to be used to characterize the four dimensional conformal fixed points considered in the first half of this dissertation.

In this thesis, we study strongly interacting superconformal field theories in two and three dimensions. In two dimensions, we investigate N = (0, 2) gauge theories using the gauged linear sigma models (GLSM). In those theories, we identify simple mechanism by which worldsheet description of H-flux satisfying Green-Schwarz Bianchi identity arises. Under the renormalization group flow, we argue that these models flow into superconformal fixed points describing string theory compactifications backgrounds with non-trivial H-flux turned on. By analyzing quantum-consistency of effective theories with such mechanism, we identify conditions under which these theories to become interacting superconformal field theories in the infrared. In three dimensions, we study maximally supersymmetric (N = 8) conformal field theories by conformal bootstrap approach. We focus on studying the four-point function of stress-tensor multiplet. The superconformal blocks for the four-point function are computed by analyzing superconformal Ward identity. Using these blocks, we study crossing symmetry constraints both numerically and analytically. Doing so, we obtain universal bounds and exact relations of N = 8 superconformal field theory data.
