Estimating the extent of spatial association of Mycobacterium bovis infection in badgers in Ireland

Mycobacterium bovis infects the wildlife species badgers Meles meles who are linked with the spread of the associated disease tuberculosis (TB) in cattle. Control of livestock infections depends in part on the spatial and social structure of the wildlife host. Here we describe spatial association of M. bovis infection in a badger population using data from the first year of the Four Area Project in Ireland. Using second-order intensity functions, we show there is strong evidence of clustering of TB cases in each the four areas, i.e. a global tendency for infected cases to occur near other infected cases. Using estimated intensity functions, we identify locations where particular strains of TB cluster. Generalized linear geostatistical models are used to assess the practical range at which spatial correlation occurs and is found to exceed 6 in all areas. The study is of relevance concerning the scale of localized badger culling in the control of the disease in cattle.

Food Competition in a Semi-Free-Ranging Cebus apella Group

The competitive regime faced by individuals is fundamental to modelling the evolution of social organization. In this paper, we assess the relative importance of contest and scramble food competition on the social dynamics of a provisioned semi-free-ranging Cebus apella group (n=18). Individuals competed directly for provisioned and clumped foods. Effects of indirect competition were apparent with individuals foraging in different areas and with increased group dispersion during periods of low food abundance. We suggest that both forms of competition can act simultaneously and to some extent synergistically in their influence on social dynamics; the combination of social and ecological opportunities for competition and how those opportunities are exploited both influence the nature of the relationships within social groups of primates and underlie the evolved social structure.

Vitellogenin content in fat body and ovary homogenates of workers and queens of Melipona quadrifasciata anthidioides during vitellogenesis

Vitellogenin (Vg) is an egg yolk protein that is produced primarily in the fat body of most female insects. In the advanced social structure of eusocial honeybees, the presence of the queen inhibits egg maturation in the workers ovaries. However in the stingless bee Melipona quadrifasciata, the workers always develop ovaries and lay a certain amount of eggs while provisioning the brood cells with larval food during what is known as the worker nurse phase. The present work is a comparative study of the presence of Vg in homogenates of the fat bodies and ovaries of the nurse workers, and the virgin and physogastric queens of M. quadrifasciata. The presence of Vg was determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis and immunoblotting using Apis mellifera anti-egg antibody. Vg was not detected in the fat bodies or ovaries of the workers, but it was found in the ovaries of virgin and physogastric queens and in the fat body of physogastric queens. The results are discussed, taking into account the reproductive state of the individuals and the other possible roles of Vg, such as a storage protein for metoabolism of other organs.

Sozialarbeit in Polen im Spannungsfeld der Systemtransformationsprozesse nach 1989

In der vorliegenden Studie werden die wesentlichen Entwicklungen in der polnischen Sozialarbeit im Bedingungszusammenhang der Systemtransformationsprozesse nach 1989 analysiert. Die Transformation des gesamten Gesellschaftssystems hat einen umfassenden Wandel der Sozialstruktur und der Kultur ausgelöst. Sie bewirkte eine rasche Zunahme sozialer Probleme, solcher wie die Verarmung breiter Teile der polnischen Gesellschaft und Massenarbeitslosigkeit und stellte somit auch hohe Herausforderung an die Sozialpolitik und Sozialarbeit der Transformationszeit. In der Arbeit werden die Probleme und die Lösungsansätze der polnischen Sozialarbeit auf der Ebene der gesellschaftlichen Rahmenbedingungen, der Ebene der Institutionen und Organisationsformen sowie auf der Interaktions- und Handlungsebene der Akteure dargestellt und reflektiert.

Phylogeny and population dynamics in European Reticulitermes and Kalotermes genera (Insecta, Isoptera)

The aim of this thesis is to detect the phylogeny and the population dynamics of the European termites of the genera Reticulitermes and Kalotermes, by the use of different mitochondrial (16S, COI/tRNA/COII, CR) and nuclear (microsatellites and Inter-SINE) molecular markers. In the phylogenetic analyses, the obtained results have well defined the cladogenetic events that generated the nowadays species biodiversity of the genus Reticulitermes, while the analysis of the Kalotermes flavicollis taxon showed the presence of at least four genetic clades, defined on the basis of the geographical distance. The second part of the thesis is centred on the population dynamics of two species: Reticulitermes urbis and Kalotermes flavicollis. The first species, native of the Balkans, is known to be present in some cities of Italy and France. I’ve analyzed the colony genetic structure of the introduced population of Bagnacavallo (RA, Italy), using nine microsatellite loci. The obtained results are in accordance with those obtained from another population in France: this species in fact confirms its invasive and infestation capacities. The analysis of the natural population of K. flavicollis, performed with a combination of mitochondrial (control region) and nuclear (microsatellites and I-SINE) markers, clearly evidenced the presence of two genetic lineages that coexist in the same area. Moreover, results clearly indicate that the cross-breeding is allowed. Finally, the whole results are discussed in a comparative view to better understand the differences in ecology, evolutionary dynamics and colony social structure between these two genera.

Einflussfaktoren der Studienfachwahl im Wandel: eine empirische Untersuchung auf Basis des Studierendensurveys

„Wer studierte was wann und warum?“ Diese Formulierung impliziert die Fragestellung und die Themenbereiche der Arbeit, die einen Beitrag zur Diskussion von Bildungsentscheidungen auf gesellschaftlicher, organisationaler und individueller Ebene leistet. Ausgangspunkt der Analyse ist eine ausführliche theoretische Einbettung des Themas anhand verschiedener Konzepte und der Aufarbeitung des Forschungsstandes. Dabei werden sozialstrukturelle Merkmale, die Bedeutung von Lebensorientierungen und der Komplex der individuellen Motivationslagen diskutiert und u.a. in Bezug zur handlungstheoretischen Unterscheidung der Um-zu- und Weil-Motive von Alfred Schütz gesetzt. Dieses Konzept und die daraus resultierenden Hypothesen werden in einer quantitativ-empirischen Analyse untersucht. Datengrundlage ist das Studierendensurvey der AG Hochschulforschung der Uni Konstanz. Anhand von binären logistischen Regressionsanalysen werden bestimmte Einflussstrukturen und fachspezifische Profile ermittelt. Insbesondere die Konzeption der intrinsischen und extrinsischen Motivationen zeichnet dabei deutliche Unterscheidungen zwischen den Fächern. Auch in der Betrachtung des Zeitraumes 1985-2007 werden Veränderungen der Einflussstrukturen der Studienfachwahl deutlich, wie z.B. die schwindende Bedeutung der sozialen Herkunft für die Studienfachwahl zeigt. Abschließend wird der Zusammenhang der Einflussstrukturen der Studienfachwahl mit der Studienzufriedenheit analysiert. Auch für die Zufriedenheit von Studierenden und damit den Studienerfolg sind bestimmte Strukturen der Studienfachwahl von Bedeutung.

A Sociological Study of the Political Subsystem in Yugoslavia

In this critical analysis of sociological studies of the political subsystem in Yugoslavia since the fall of communism Mr. Ilic examined the work of the majority of leading researchers of politics in the country between 1990 and 1996. Where the question of continuity was important, he also looked at previous research by the writers in question. His aim was to demonstrate the overall extent of existing research and at the same time to identify its limits and the social conditions which defined it. Particular areas examined included the problems of defining basic concepts and selecting the theoretically most relevant indicators; the sources of data including the types of authentic materials exploited; problems of research work (contacts, field control, etc.); problems of analysisl and finally the problems arising from different relations with the people who commission the research. In the first stage of the research, looking at methods of defining key terms, special attention was paid to the analysis of the most frequently used terms such as democracy, totalitarianism, the political left and right, and populism. Numerous weaknesses were noted in the analytic application of these terms. In studies of the possibilities of creating a democratic political system in Serbia and its possible forms (democracy of the majority or consensual democracy), the profound social division of Serbian society was neglected. The left-right distinction tends to be identified with the government-opposition relation, in the way of practical politics. The idea of populism was used to pass responsibility for the policy of war from the manipulator to the manipulated, while the concept of totalitarianism is used in a rather old-fashioned way, with echoes of the cold war. In general, the terminology used in the majority of recent research on the political subsystem in Yugoslavia is characterised by a special ideological style and by practical political material, rather than by developed theoretical effort. The second section of analysis considered the wider theoretical background of the research and focused on studies of the processes of transformation and transition in Yugoslav society, particularly the work of Mladen Lazic and Silvano Bolcic, who he sees as representing the most important and influential contemporary Yugoslav sociologists. Here Mr. Ilic showed that the meaning of empirical data is closely connected with the stratification schemes towards which they are oriented, so that the same data can have different meanings in shown through different schemes. He went on to show the observed theoretical frames in the context of wider ideological understanding of the authors' ideas and research. Here the emphasis was on the formalistic character of such notions as command economy and command work which were used in analysing the functioning and the collapse of communist society, although Mr. Ilic passed favourable judgement on the Lazic's critique of political over-determination in its various attempts to explain the disintegration of the communist political (sub)system. The next stage of the analysis was devoted to the problem of empirical identification of the observed phenomena. Here again the notions of the political left and right were of key importance. He sees two specific problems in using these notion in talking about Yugoslavia, the first being that the process of transition in the FR Yugoslavia has hardly begun. The communist government has in effect remained in power continuously since 1945, despite the introduction of a multi-party system in 1990. The process of privatisation of public property was interrupted at a very early stage and the results of this are evident on the structural level in the continuous weakening of the social status of the middle class and on the political level because the social structure and dominant form of property direct the majority of votes towards to communists in power. This has been combined with strong chauvinist confusion associated with the wars in Croatia and Bosnia, and these ideas were incorporated by all the relevant Yugoslav political parties, making it more difficult to differentiate between them empirically. In this context he quotes the situation of the stream of political scientists who emerged in the Faculty of Political Science in Belgrade. During the time of the one-party regime, this faculty functioned as ideological support for official communist policy and its teachers were unable to develop views which differed from the official line, but rather treated all contrasting ideas in the same way, neglecting their differences. Following the introduction of a multi-party system, these authors changed their idea of a public enemy, but still retained an undifferentiated and theoretically undeveloped approach to the issue of the identification of political ideas. The fourth section of the work looked at problems of explanation in studying the political subsystem and the attempts at an adequate causal explanation of the triumph of Slobodan Milosevic's communists at four subsequent elections was identified as the key methodological problem. The main problem Mr. Ilic isolated here was the neglect of structural factors in explaining the voters' choice. He then went on to look at the way empirical evidence is collected and studied, pointing out many mistakes in planning and determining the samples used in surveys as well as in the scientifically incorrect use of results. He found these weaknesses particularly noticeable in the works of representatives of the so-called nationalistic orientation in Yugoslav sociology of politics, and he pointed out the practical political abuses which these methodological weaknesses made possible. He also identified similar types of mistakes in research by Serbian political parties made on the basis of party documentation and using methods of content analysis. He found various none-sided applications of survey data and looked at attempts to apply other sources of data (statistics, official party documents, various research results). Mr. Ilic concluded that there are two main sets of characteristics in modern Yugoslav sociological studies of political subsystems. There are a considerable number of surveys with ambitious aspirations to explain political phenomena, but at the same time there is a clear lack of a developed sociological theory of political (sub)systems. He feels that, in the absence of such theory, most researcher are over-ready to accept the theoretical solutions found for interpretation of political phenomena in other countries. He sees a need for a stronger methodological bases for future research, either 1) in complementary usage of different sources and ways of collecting data, or 2) in including more of a historical dimension in different attempts to explain the political subsystem in Yugoslavia.

Expected and Unexpected Consequences of the Educational Expansion in Europe and the US. Theoretical approaches and empirical findings in comparative perspective

A main mechanism behind the change in European and North American societies in the second half of the 20th century is the educational expansion, i.e. the increase in educational opportunities and the higher demand for education. Whereas other abstract social processes like modernization have been widely theorized in social science literature, the educational expansion and its consequences in particular have not been well studied. Therefore the main aim of this compilation is to deal with the question of whether the demands of the educational reforms have been fulfilled and which other consequences the educational expansion has had. This book will focus on consequences of the educational expansion for individuals and their life courses as well as for the social structure and other societal areas such as culture and politics. Aspects that will be analysed in the light of educational expansion include participation in education, educational inequalities, labour market outcomes, educational returns, and gender differences as well as crime, life expectancy, and lifestyles. Countries analysed in the book include West European countries like Germany, France, Italy and Spain, East European countries (Hungary, Poland, and the Czech Republic) as well as the US.

Education and Ideologies of the Knowledge Economy: Europe and the Politics of Emulation

The Austrian philosopher Ludwig Wittgenstein famously proposed a style of philosophy that was directed against certain pictures [bild] that tacitly direct our language and forms of life. His aim was to show the fly the way out of the fly bottle and to fight against the bewitchment of our intelligence by means of language: “A picture held us captive. And we could not get outside it, for it lay in our language and language seemed to repeat it to us inexorably” (Wittgenstein 1953, 115). In this context Wittgenstein is talking of philosophical pictures, deep metaphors that have structured our language but he does also use the term picture in other contexts (see Owen 2003, 83). I want to appeal to Wittgenstein in my use of the term ideology to refer to the way in which powerful underlying metaphors in neoclassical economics have a strong rhetorical and constitutive force at the level of public policy. Indeed, I am specifically speaking of the notion of ‘the performative’ in Wittgenstein and Austin. The notion of the knowledge economy has a prehistory in Hayek (1937; 1945) who founded the economics of knowledge in the 1930s, in Machlup (1962; 1970), who mapped the emerging employment shift to the US service economy in the early 1960s, and to sociologists Bell (1973) and Touraine (1974) who began to tease out the consequences of these changes for social structure in the post-industrial society in the early 1970s. The term has been taken up since by economists, sociologists, futurists and policy experts recently to explain the transition to the so-called ‘new economy’. It is not just a matter of noting these discursive strands in the genealogy of the ‘knowledge economy’ and related or cognate terms. We can also make a number of observations on the basis of this brief analysis. First, there has been a succession of terms like ‘postindustrial economy’, ‘information economy’, ‘knowledge economy’, ‘learning economy’, each with a set of related concepts emphasising its social, political, management or educational aspects. Often these literatures are not cross-threading and tend to focus on only one aspect of phenomena leading to classic dichotomies such as that between economy and society, knowledge and information. Second, these terms and their family concepts are discursive, historical and ideological products in the sense that they create their own meanings and often lead to constitutive effects at the level of policy. Third, while there is some empirical evidence to support claims concerning these terms, at the level of public policy these claims are empirically underdetermined and contain an integrating, visionary or futures component, which necessarily remains untested and is, perhaps, in principle untestable.

Is the Market Eroding Moral Norms? A Micro-Analytical Validation of Some Ideas of Anomie Theory

Anomie theorists have been reporting the suppression of shared welfare orientations by the overwhelming dominance of economic values within capitalist societies since before the outset of neoliberalism debate. Obligations concerning common welfare are more and more often subordinated to the overarching aim of realizing economic success goals. This should be especially valid with for social life in contemporary market societies. This empirical investigation examines the extent to which market imperatives and values of the societal community are anchored within the normative orientations of market actors. Special attention is paid to whether the shape of these normative orientations varies with respect to the degree of market inclusion. Empirical analyses, based on the data of a standardized written survey within the German working population carried out in 2002, show that different types of normative orientation can be distinguished among market actors. These types are quite similar to the well-known types of anomic adaptation developed by Robert K. Merton in “Social Structure and Anomie” and are externally valid with respect to the prediction of different forms of economic crime. Further analyses show that the type of normative orientation actors adopt within everyday life depends on the degree of market inclusion. Confirming anomie theory, it is shown that the individual willingness to subordinate matters of common welfare to the aim of economic success—radical market activism—gets stronger the more actors are included in the market sphere. Finally, the relevance of reported findings for the explanation of violent behavior, especially with view to varieties of corporate violence, is discussed.

Körper im Kulturkonflikt. Zur Vermittlung und Aushandlung von Normen und Werten in Schwimmkursen für Frauen mit Migrationshintergrund

Ausgehend vom Körper als Vermittler zwischen Subjekt und Gesellschaft wird die Frage beantwortet, wie Migrantinnen auf diskursiv erzeugte Normen und Werte der schweizerischen Mehrheitsgesellschaft im Kontext von Schwimmkursen als Integrationsmaßnahme reagieren. Die Feldaufenthalte und Interviews erlauben eine Analyse dominanter Macht- und subversiver Selbstermächtigungsprozesse innerhalb eines körperzentrierten, religiös-kulturell pluralisierten und ethnisch differenzierten Feldes. Hierbei werden Divergenzen in der verkörperten und objektiven Sozialstruktur sichtbar, was sich beispielsweise in den kontrovers geführten Debatten zur Wahl der Badekleidung und Badnutzung verdeutlicht. Bei den Aushandlungen um die Durchsetzung von Deutungs- sowie Ordnungsmustern lassen sich Prozesse der kulturellen Anpassung, Anknüpfung und des Neuentwurfs beobachten.

Efficient team actions: Outline of a theory of teams in sport

So far, social psychology in sport has preliminary focused on team cohesion, and many studies and meta analyses tried to demonstrate a relation between cohesiveness of a team and it's performance. How a team really co-operates and how the individual actions are integrated towards a team action is a question that has received relatively little attention in research. This may, at least in part, be due to a lack of a theoretical framework for collective actions, a dearth that has only recently begun to challenge sport psychologists. In this presentation a framework for a comprehensive theory of teams in sport is outlined and its potential to integrate the following presentations is put up for discussion. Based on a model developed by von Cranach, Ochsenbein and Valach (1986), teams are information processing organisms, and team actions need to be investigated on two levels: the individual team member and the group as an entity. Elements to be considered are the task, the social structure, the information processing structure and the execution structure. Obviously, different task require different social structures, communication and co-ordination. From a cognitivist point of view, internal representations (or mental models) guide the behaviour mainly in situations requiring quick reactions and adaptations, were deliberate or contingency planning are difficult. In sport teams, the collective representation contains the elements of the team situation, that is team task and team members, and of the team processes, that is communication and co-operation. Different meta-perspectives may be distinguished and bear a potential to explain the actions of efficient teams. Cranach, M. von, Ochsenbein, G., & Valach, L.

AIDS talk

The observations of Michel Foucault, noted Twentieth Century French philosopher, regarding modern power relations and orders of discourse, form the framework utilized to analyze and interpret the power struggles of AIDS activists and their opponents--the religious and radical right, and the administrative agencies of the 'Liberal' welfare State. Supported by the tools of sociolinguistic inquiry, the analysis highlights the success of a safer sex campaign in Houston, Texas to illustrate the dynamics of cultural and political change by means of discursive transformations initiated by the gay micro-culture. The KS/AIDS Foundation, allied with both the biomedical community and gay entertainment spheres, was successful in conveying biomedical cautions that resulted in altered personal behavior and modified public attitudes by using linguistic conventions consonant with the discourse of the Houston gay micro-culture. The transformation of discursive practices transgressed not only the Houston gay micro-culture's boundaries, but the city boundaries of Houston as well. In addition to cultural and political change, moderate and confrontational gay activists also sought to change the cognitive boundaries surrounding 'the gold standard' for clinical research trials.^ From a Foucauldian perspective, the same-sex community evolved from the subordinated Other to a position of power in a period of five years. Transformations in discursive practices and power relations are exemplified by the changing definitions employed by AIDS policy-makers, the public validation of community-based research and the establishment of parallel track drug studies. Finally, transformations in discursive practices surrounding the issues of HIV antibody testing are interpreted using Foucault's six points of power relations. The Montrose Clinic provides the case study for this investigation. The clinic turned the technical rationalities of the State against itself to achieve its own ends and those of the gay micro-culture--anonymous testing with pre and post test counseling. AIDS Talk portrays a dramatic transformation in discursive practices and power relations that transcends the historical moment to provide a model for future activists.

The door of the tomb is open: Participatory action research to assess the impact of strengthened community capacity on maternal health care in rural Mali

This participatory action-research project addressed the hypothesis that strengthened community and women's capacity for self-development will lead to action to address maternal health problems and the prevention of maternal morbidity and mortality in Mali. Research objectives were: (1) to undertake a comparative cross-sectional study of the association of community capacity with improved maternal health in rural areas of Sanando, Mali, where capacity building interventions have taken place in some villages but not in others. (2) to describe women's maternal health status, access to and use of maternal health services given their residence in program or comparison communities.^ The participatory action research project was an integrated qualitative and quantitative study using participatory rural appraisal exercises, semi-structured group interviews and a cross-sectional survey.^ Factors related to community capacity for self-development were identified: community harmony; an understanding of the benefits of self-development; dynamic leadership; and a structure to implement collective activities.^ A distinct difference between the program and comparison villages was the commitment to train and support traditional birth attendants (TBAs). The TBAs in the program villages work in the context of the wider, integrated self-development program and, 10 years after their initial training, the TBAs continue to practice.^ Many women experience labor and childbirth alone or are attended by an untrained relative in both program and comparison villages. Nevertheless a significant change is apparent, with more women in program villages than in comparison villages being assisted by the TBAs. The delivery practices of the TBAs reveal the positive impact of their training in the "three cleans" (clean hands of the assistant, clean delivery surface and clean cord-cutting). The findings of this study indicate a significant level of unmet need for child spacing methods in all villages.^ The training and support of TBAs in the program villages yielded significant improvements in their delivery practices, and resulting outcomes for women and infants. However, potential exists for further community action. Capacities for self-development have not yet been directed toward an action plan encompassing other Safe Motherhood interventions, including access to family planning services and emergency obstetric care services. ^
