Bourgin-Yang version of the Borsuk-Ulam theorem for Z(pk)-equivariant maps

Let G = Z(pk) be a cyclic group of prime power order and let V and W be orthogonal representations of G with V-G = W-G = W-G = {0}. Let S(V) be the sphere of V and suppose f: S(V) -> W is a G-equivariant mapping. We give an estimate for the dimension of the set f(-1){0} in terms of V and W. This extends the Bourgin-Yang version of the Borsuk-Ulam theorem to this class of groups. Using this estimate, we also estimate the size of the G-coincidences set of a continuous map from S(V) into a real vector space W'.

What do medical students think about their quality of life? A qualitative study

Background: Medical education can affect medical students' physical and mental health as well as their quality of life. The aim of this study was to assess medical students' perceptions of their quality of life and its relationship with medical education. Methods: First-to sixth-year students from six Brazilian medical schools were interviewed using focus groups to explore what medical student's lives are like, factors related to increases and decreases of their quality of life during medical school, and how they deal with the difficulties in their training. Results: Students reported a variety of difficulties and crises during medical school. Factors that were reported to decrease their quality of life included competition, unprepared teachers, excessive activities, and medical school schedules that demanded exclusive dedication. Contact with pain, death and suffering and harsh social realities influence their quality of life, as well as frustrations with the program and insecurity regarding their professional future. The scarcity of time for studying, leisure activities, relationships, and rest was considered the main factor of influence. Among factors that increase quality of life are good teachers, classes with good didactic approaches, active learning methodologies, contact with patients, and efficient time management. Students also reported that meaningful relationships with family members, friends, or teachers increase their quality of life. Conclusion: Quality of teachers, curricula, healthy lifestyles related to eating habits, sleep, and physical activity modify medical students' quality of life. Lack of time due to medical school obligations was a major impact factor. Students affirm their quality of life is influenced by their medical school experiences, but they also reframe their difficulties, herein represented by their poor quality of life, understood as necessary and inherent to the process of becoming doctors.

Food safety in wine: optimization of analytical controls and evaluation of production technologies

This PhD thesis has been proposed to validate and then apply innovative analytical methodologies for the determination of compounds with harmful impact on human health, such as biogenic amines and ochratoxin A in wines. Therefore, the influence of production technology (pH, amino acids precursor and use of different malolactic starters) on biogenic amines content in wines was evaluated. An HPLC method for simultaneous determination of amino acids and amines with precolumnderivatization with 9-Fluorenyl-methoxycarbonyl chloride (FMOC-Cl) and UV detection was developed. Initially, the influence of pH, time of derivatization, gradient profile were studied. In order to improve the separation of amino acids and amines and reduce the time of analysis, it was decided to study the influence of different flows and the use of different columns in the chromatographic method. Firstly, a C18 Luna column was used and later two monolithic columns Chromolith in series. It appeared to be suitable for an easy, precise and accurate determination of a relatively large number of amino acids and amines in wines. This method was then applied on different wines produced in the Emilia Romagna region. The investigation permitted to discriminate between red and white wines. Amino acids content is related to the winemaking process. Biogenic amines content in these wines does not represent a possible toxicological problem for human health. The results of the study of influence of technologies and wine composition demonstrated that pH of wines and amino acids content are the most important factors. Particularly wines with pH > 3,5 show higher concentration of biogenic amines than wines with lower pH. The enrichment of wines by nutrients also influences the content of some biogenic amines that are higher in wines added with amino acids precursors. In this study, amino acids and biogenic amines are not statistically affected by strain of lactic acid bacteria inoculated as a starter for malolactic fermentation. An evaluation of different clean-up (SPE-MycoSep; IACs and LLE) and determination methods (HPLC and ELISA) of ochratoxin A was carried out. The results obtained proved that the SPE clean-up are reliable at the same level while the LLE procedures shows lowest recovery. The ELISA method gave a lower determination and a low reproducibility than HPLC method.

The assessment of change in rural landscape and the analysis of the driving forces. Proposal of a spatial model for the rural built environment

The presented study carried out an analysis on rural landscape changes. In particular the study focuses on the understanding of driving forces acting on the rural built environment using a statistical spatial model implemented through GIS techniques. It is well known that the study of landscape changes is essential for a conscious decision making in land planning. From a bibliography review results a general lack of studies dealing with the modeling of rural built environment and hence a theoretical modelling approach for such purpose is needed. The advancement in technology and modernity in building construction and agriculture have gradually changed the rural built environment. In addition, the phenomenon of urbanization of a determined the construction of new volumes that occurred beside abandoned or derelict rural buildings. Consequently there are two types of transformation dynamics affecting mainly the rural built environment that can be observed: the conversion of rural buildings and the increasing of building numbers. It is the specific aim of the presented study to propose a methodology for the development of a spatial model that allows the identification of driving forces that acted on the behaviours of the building allocation. In fact one of the most concerning dynamic nowadays is related to an irrational expansion of buildings sprawl across landscape. The proposed methodology is composed by some conceptual steps that cover different aspects related to the development of a spatial model: the selection of a response variable that better describe the phenomenon under study, the identification of possible driving forces, the sampling methodology concerning the collection of data, the most suitable algorithm to be adopted in relation to statistical theory and method used, the calibration process and evaluation of the model. A different combination of factors in various parts of the territory generated favourable or less favourable conditions for the building allocation and the existence of buildings represents the evidence of such optimum. Conversely the absence of buildings expresses a combination of agents which is not suitable for building allocation. Presence or absence of buildings can be adopted as indicators of such driving conditions, since they represent the expression of the action of driving forces in the land suitability sorting process. The existence of correlation between site selection and hypothetical driving forces, evaluated by means of modeling techniques, provides an evidence of which driving forces are involved in the allocation dynamic and an insight on their level of influence into the process. GIS software by means of spatial analysis tools allows to associate the concept of presence and absence with point futures generating a point process. Presence or absence of buildings at some site locations represent the expression of these driving factors interaction. In case of presences, points represent locations of real existing buildings, conversely absences represent locations were buildings are not existent and so they are generated by a stochastic mechanism. Possible driving forces are selected and the existence of a causal relationship with building allocations is assessed through a spatial model. The adoption of empirical statistical models provides a mechanism for the explanatory variable analysis and for the identification of key driving variables behind the site selection process for new building allocation. The model developed by following the methodology is applied to a case study to test the validity of the methodology. In particular the study area for the testing of the methodology is represented by the New District of Imola characterized by a prevailing agricultural production vocation and were transformation dynamic intensively occurred. The development of the model involved the identification of predictive variables (related to geomorphologic, socio-economic, structural and infrastructural systems of landscape) capable of representing the driving forces responsible for landscape changes.. The calibration of the model is carried out referring to spatial data regarding the periurban and rural area of the study area within the 1975-2005 time period by means of Generalised linear model. The resulting output from the model fit is continuous grid surface where cells assume values ranged from 0 to 1 of probability of building occurrences along the rural and periurban area of the study area. Hence the response variable assesses the changes in the rural built environment occurred in such time interval and is correlated to the selected explanatory variables by means of a generalized linear model using logistic regression. Comparing the probability map obtained from the model to the actual rural building distribution in 2005, the interpretation capability of the model can be evaluated. The proposed model can be also applied to the interpretation of trends which occurred in other study areas, and also referring to different time intervals, depending on the availability of data. The use of suitable data in terms of time, information, and spatial resolution and the costs related to data acquisition, pre-processing, and survey are among the most critical aspects of model implementation. Future in-depth studies can focus on using the proposed model to predict short/medium-range future scenarios for the rural built environment distribution in the study area. In order to predict future scenarios it is necessary to assume that the driving forces do not change and that their levels of influence within the model are not far from those assessed for the time interval used for the calibration.

Die Re-Definition der Wirklichkeit durch Motto-Events

Eine aktuelle Ausprägung der Veranstaltungslandschaft sind die so genannten Motto-Events, die die Inszenierung einer Anderswelt-Konstruktion einsetzen, um emotionale und kommunikatorische Ziele zu erreichen. Dabei werden themengebundene Entwürfe räumlich und inhaltlich in die lebensweltliche Wirklichkeit transportiert und auf diese Weise eine dynamische und integrative Scheinwelt erschaffen. In dieser konstruierten Welt können schließlich Abenteuer erlebt und heroische Taten begangen werden. Durch die reziproke Beeinflussung von Inszenierung und Handlung befinden sich die Akteure außerhalb der gesellschaftlichen Norm, sie erleben innerhalb der "gated community" der Motto-Veranstaltung eine re-definierte Wirklichkeit. Aus einer Kombination von aktiven und passiven Elementen werden homogene Klischees inszeniert, die durch ihren Bekanntheitsgrad eine hohe Anschlussfähigkeit der Teilnehmer garantieren. Die vorliegende Arbeit beschäftigt sich mit den Mechanismen, die diese re-definierte Wirklichkeit in Szene setzen. Dadurch wird es möglich, in einer zusammenfassenden Betrachtung die Rezeption verschiedener Event-Modelle zu beschreiben und Handlungsempfehlungen zu geben.

Entrepreneurship influential factors in development of rural tourism as diversified rural activity in Republic of Macedonia

Rural tourism is relatively new product in the process of diversification of the rural economy in Republic of Macedonia. This study used desk research and life story interviews of rural tourism entrepreneurs as qualitative research method to identify prevalent success influential factors. Further quantitative analysis was applied in order to measure the strength of influence of identified success factors. The primary data for the quantitative research was gathered using telephone questionnaire composed of 37 questions with 5-points Likert scale. The data was analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) by SmartPLS 3.1.6. Results indicated that human capital, social capital, entrepreneurial personality and external business environment are predominant influential success factors. However, human capital has non-significant direct effect on success (p 0.493) nonetheless the effect was indirect with high level of partial mediation through entrepreneurial personality as mediator (VAF 73%). Personality of the entrepreneur, social capital and business environment have direct positive affect on entrepreneurial success (p 0.001, 0.003 and 0.045 respectably). Personality also mediates the positive effect of social capital on entrepreneurial success (VAF 28%). Opposite to the theory the data showed no interaction between social and human capital on the entrepreneurial success. This research suggests that rural tourism accommodation entrepreneurs could be more successful if there is increased support in development of social capital in form of conservation of cultural heritage and natural attractions. Priority should be finding the form to encourage and support the establishment of formal and informal associations of entrepreneurs in order to improve the conditions for management and marketing of the sector. Special support of family businesses in the early stages of the operation would have a particularly positive impact on the success of rural tourism. Local infrastructure, access to financial instruments, destination marketing and entrepreneurial personality have positive effect on success.

Das deutsche Kriegsgefangenenwesen 1939 - 1945

Zusammenfassung: Die vorliegende Untersuchung zum deutschen Kriegsgefangenenwesen (KGW) im Zweiten Weltkrieg schließt eine wichtige Lücke innerhalb der geschichtswissenschaftlichen Forschungen zum Themenkreis der Kriegsgefangenschaft in deutschem Gewahrsam. Bisherige Studien (bis einschließlich 1997) behandeln vor allem sozial- und kulturgeschichtliche Aspekte der Kriegsgefangenen (Kgf.), der Lagergesellschaft und dem Alltag von Soldaten in Kriegsgefangenschaft. Der Verfasser indes legt mit seiner Magisterarbeit erstmals eine Organisations- und Strukturgeschichte des deutschen Kriegsgefangenenwesens von 1939 bis 1945 vor, welche fundamentale Grundlagen der deutschen militärischen Lagerorganisation und Verwaltung dokumentiert. So wird die Entwicklung von den Vorkriegsplanungen bis zum Kriegsende anhand der zentralen Dienststellen herausgearbeitet und im Kontext des Genfer Kriegsgefangenenabkommens von 1929 und völkerrechtlicher Implikationen gewichtet. Hiermit untrennbar verbundene Einflußnahmen nichtmilitärischer Stellen in die Entscheidungsgewalt der Streitkräfte im Heimatkriegsgebiet und in den Wehrmachtbefehlshaberbereichen werden nicht zuletzt auch anhand mehrerer Organigramme veranschaulicht. Zudem dokumentiert und analysiert die Untersuchung die im Kriegsverlauf stetig verschärften Maßnahmen zur Fluchtprävention und der konzertierten Fahndung nach geflohenen Kriegsgefangenen: Die Machterosion des Oberkommandos der Wehrmacht (OKW) zugunsten des Reichsführers-SS, des Reichssicherheitshauptamts und nicht zuletzt der Parteikanzlei der NSDAP wird so augenfällig. Trotz eminenter Schriftgutverluste kann der Verfasser vor allem anhand einer nahezu vollständig erhaltenen Schlüsselquelle die Stellenbesetzung und Organisationsstruktur der mit Kriegsgefangenenfragen befassten Stellen im OKW rekonstruieren. Die Auswertung dieser Sammelmitteilungen / Befehlssammlung für das Kriegsgefangenenwesen sowie an anderer Stelle überlieferter Organisationsbefehle ermöglicht wichtige Änderungen am derzeitigen Forschungsstand. Darüber hinaus beschäftigt sich die vorliegende Untersuchung mit dem Arbeitseinsatz Kriegsgefangener in der deutschen Wirtschaft als in der zweiten Kriegshälfte zentralem Element der Kriegsgefangenschaft. Außerdem wird beleuchtet, welche politischen, (rassen)ideologischen oder reziprok konnotierten Faktoren den Stellenwert gefangener Soldaten unterschiedlicher Nationalität innerhalb der Gefangenenhierarchie im deutschen Kriegsgefangenenwesen bestimmten.

Stratified Boston: The Brahmins, the Irish and the Boston Police Strike of 1919

This thesis explores the Boston Police Strike of 1919 through the lens of class struggle and ethnic tension. Through an examination of the development of Boston’s class structure, particularly focused on the upper class Brahmins and the Irish working class, it concludes that the Brahmins’ success in suppressing the police strikeallowed for their maintenance of socioeconomic power within the city despite their relatively small population. Based on their extreme class cohesion resulting from the growing prominence of Harvard University as well as the Brahmins’ unabashed discrimination against their ethnic neighbors in almost every sphere of society, theBrahmins were able to maintain their power in Boston’s cultural world. The Irish working class, on the other hand, which attempted to use the increasing popularity of public and police unionization to challenge the status and power of the Brahmins through the creation of the Boston Police Union and subsequently through the notorious Boston Police Strike of 1919 was ultimately unsuccessful, and it was left in the same position in which it started, at the bottom of the social ladder. The suppression of the strike by members of the upper class and their allies, particularly those in high government positions, served to preserve and affirm the socioeconomic power of the Brahmins over much of Boston society and brought the era of public police unionization to a close.

Investigating the Effects of Various Crowd Characteristics on the Dynamic Properties of an Occupied Structure

One of the challenges for structural engineers during design is considering how the structure will respond to crowd-induced dynamic loading. It has been shown that human occupants of a structure do not simply add mass to the system when considering the overall dynamic response of the system, but interact with it and may induce changes of the dynamic properties from those of the empty structure. This study presents an investigation into the human-structure interaction based on several crowd characteristics and their effect on the dynamic properties of an empty structure. The dynamic properties including frequency, damping, and mode shapes were estimated for a single test structure by means of experimental modal analysis techniques. The same techniques were utilized to estimate the dynamic properties when the test structure was occupied by a crowd with different combinations of size, posture, and distribution. The goal of this study is to isolate the occupant characteristics in order to determine the significance of each to be considered when designing new structures to avoid crowd serviceability issues. The results are presented and summarized based on the level of influence of each characteristic. The posture that produces the most significant effects based on the scope of this research is standing with bent knees with a maximum decrease in frequency of the first mode of the empty structure by 32 percent atthe highest mass ratio. The associated damping also increased 36 times the damping of the empty structure. In addition to the analysis of the experimental data, finite element models and a two degree-of-freedom model were created. These models were used to gain an understanding of the test structure, model a crowd as an equivalent mass, and also to develop a single degree-of-freedom (SDOF) model to best represent a crowd of occupants based on the experimental results. The SDOF models created had an averagefrequency of 5.0 Hz, within the range presented in existing biomechanics research, and combined SDOF systems of the test structure and crowd were able to reproduce the frequency and damping ratios associated with experimental tests. Results of this study confirmed the existence of human-structure interaction andthe inability to simply model a crowd as only additional mass. The two degree-offreedom model determined was able to predict the change in natural frequency and damping ratio for a structure occupied by multiple group sizes in a single posture. These results and model are the preliminary steps in the development of an appropriate methodfor modeling a crowd in combination with a more complex FE model of the empty structure.

I want to be my own person: the meaning-making and psychosocial processes of legacy students at Bucknell University

This study examined the meaning-making and psychosocial processes of five female legacy students at Bucknell University, each of whom having had at least one parent graduate from the institution. With a research philosophy, design, and methodology rooted in qualitative inquiry and phenomenology, inductive data analysis led to three primary categories that underscored legacy identity development. The first, Paradox of Influence and Identity, revealed through six themes nuanced experiences of separation-individuation. Second, Teaching and Learning, comprised of five themes, illuminated the impact of family — and of Bucknell parent alumni in particular — on their children’s internal working models. Lastly, Bucknell — the Environmental Contextand the five themes grouped therein highlighted the contributions of University community members, and of the campus culture and climate itself, to the co-construction of psychosocial formation. A tentative outline of grounded theory was offered, which explored categorical relationships; Paradox of Influence and Identity emerged as thedominant phenomenon, informing and being reinforced by the data of Teaching and Learning and Bucknell — the Environmental Context. Provisional intervention strategies for student affairs practice, in the contexts of academics, residential life, and career development, were discussed. Further, triangulated research is needed to substantiate and evolve the findings and theoretical model of this thesis.

Association between symptoms and quality of life in patients with schizophrenia: a pooled analysis of changes over time

Quality of life is an important outcome in the treatment of patients with schizophrenia. It has been suggested that patients' quality of life ratings (referred to as subjective quality of life, SQOL) might be too heavily influenced by symptomatology to be a valid independent outcome criterion. There has been only limited evidence on the association of symptom change and changes in SQOL over time. This study aimed to examine the association between changes in symptoms and in SQOL among patients with schizophrenia. A pooled data set was obtained from eight longitudinal studies that had used the Brief Psychiatric Rating Scale (BPRS) for measuring psychiatric symptoms and either the Lancashire Quality of Life Profile or the Manchester Short Assessment of Quality of Life for assessing SQOL. The sample comprised 886 patients with schizophrenia. After controlling for heterogeneity of findings across studies using linear mixed models, a reduction in psychiatric symptoms was associated with improvements in SQOL scores. In univariate analyses, changes in all BPRS subscales were associated with changes in SQOL scores. In a multivariate model, only associations between changes in the BPRS depression/anxiety and hostility subscales and changes in SQOL remained significant, with 5% and 0.5% of the variance in SQOL changes being attributable to changes in depression/anxiety and hostility respectively. All BPRS subscales together explained 8.5% of variance. The findings indicate that SQOL changes are influenced by symptom change, in particular in depression/anxiety. The level of influence is limited and may not compromise using SQOL as an independent outcome measure.

Language Construction of Reality in the German Tabloid Press/on Materials of BILD Newspaper/

From the moment of their birth, a person's life is determined by their sex. Goroshko wanted to find out why this difference is so striking, why society is so determined to sustain it, and how it can persist even when certain national or behavioural stereotypes are erased. She believes there are both social and biological differences between men and women, and set out to analyse these distinctions as they are manifested in language. Certain general characteristics can be identified. Males tend to write with less fluency, to refer to events in a verb phrase, to be time-oriented, to involve themselves more in their references to events, to locate events in their personal sphere of activity, and to refer less to others. Goroshko therefore concludes that the male is more active, more ego-involved in what he does and less concerned about others. Women were more fluent, referred to events in a noun-phrase, were less time-oriented, tended to be less involved in their event references, located events within their interactive community, and referred more to others. They spent much more time discussing personal and domestic subjects, relationship problems, family, health and reproductive matters, weight, food and clothing, men, and other women. Computer analysis showed that female speech was substantially more emotional, using hyperbole, metaphor, comparisons, epithets, ways of enumeration, interjections, rhetorical questions and exclamations. The level of literacy was higher in female speech, and women made fewer grammatical and spelling mistakes in written texts. Goroshko believes that her findings have relevance beyond the linguistic field. When working on anonymous texts she has been able to decide on the sex of the author and so believes that her research may even be of benefit to forensic science.

Civil Society and Political Parties in the Period of Transition

The major aim of Mr. Marada's project was to investigate the role of political parties on the one hand, and various institutional forms of civil society on the other, in the process of establishing mechanisms of political decision-making and policy-formation in Czechoslovakia and the Czech Republic, after November 1989. Mr. Marada wanted to examine what consequences the interplay and tensions between political parties and institutions of civil society had on the status and practical understanding of citizenship and civil society. At the beginning of his research Mr. Marada found that, while the sphere of the political was relatively clearly defined, the phenomenon of civil society required a conceptual clarification. He devoted a great deal of time to analysing the emergence, development, and disintegration of Civic Forum as the major agent of the regime change and subsequent political reforms. Alongside this analysis is a commentary on Czech society in general, drawing on established research to show how, as yet, a kind of civic incompetence reigns within the country, and how this situation has its roots in the belief, promoted by politicians themselves, that politics is an activity for experts only. The final outcome of his research took the form of a series of articles, in English, totalling 40 pages.

Rhetorics and Practices of Modernisation in Russian Industry: a Reflective Analysis of Organisational Cultures in Transition

This research was based on the results of a case study of a large confectionery factory in the Russian city of Samara. The concept of paternalism is clear in many features of the life of Russian enterprises, including the rhetoric and strategy of the management, relationships within the labour force and the stereotypical expectations of workers. The concept also has a much wider bearing, embracing the spheres of state policy, the social, and family relationships, that is every sphere of social life in which the patriarchal, communal, stereotyped way of thinking of the Soviet people is reproduced. A substantial proportion of the state's role in providing social protection for the population is carried out through enterprises. In spite of low salaries and the absence of career opportunities, female workers were as strongly attached to the enterprise as to their homes. Romanov's research showed how the development of capitalism in industries in Russia is destroying the cultural and social identities of female workers and is contributing to gender inequality. Interpersonal relations are becoming increasingly utilitarian and distant and the basic features of the patriarchal type of administrative control are becoming blurred. This control is becoming more subtle, but gender segregation is preserved in the new framework and indeed becoming more obvious, being reproduced both at the departmental level and in the hiring policy of the enterprise as a whole.
