Auch in Deutschland versuchen immer mehr Touristiker vom Pilgerboom zu profitieren. Die neuen Wege werden oft nur wenig genutzt. Wer versteht, was Pilgern ausmacht, kann auch erfolgreich agieren. Auf Basis eines empirischen Forschungsprojektes entfaltet der Beitrag das Spezifikum des Pilgerns als einen bestimmten Erfahrungsmodus: Pilger erfahren sich selbst eingebunden in den Zusammenhang des Seins, einen sie tragenden Grund. Es geht um ein Unverfügbares, dem sie sich überlassen, weil es Gewissheit stiftet. Dies setzt dem touristischen Inszenieren enge Grenzen. Werden diese beachtet, entstehen nachhaltige und erfahrungswirksame Pilgerwege. Schlagworte: Pilgern, Erfahrung, Körper, Natur

Childhood traumatic events may lead to long-lasting psychological effects and contribute to the development of complex posttraumatic sequelae. These might be captured by the diagnostic concept of complex posttraumatic stress disorder (CPTSD) as an alternative to classic posttraumatic stress disorder (PTSD). CPTSD comprises a further set of symptoms in addition to those of PTSD, namely, changes in affect, self, and interpersonal relationships. Previous empirical research on CPTSD has focused on middle-aged adults but not on older adults. Moreover, predictor models of CPTSD are still rare. The current study investigated the association between traumatic events in childhood and complex posttraumatic stress symptoms in older adults. The mediation of this association by 2 social-interpersonal factors (social acknowledgment as a survivor and dysfunctional disclosure) was investigated. These 2 factors focus on the perception of acknowledgment by others and either the inability to disclose traumatic experiences or the ability to do so only with negative emotional reactions. A total of 116 older individuals (age range = 59–98 years) who had experienced childhood traumatic events completed standardized self-report questionnaires indexing childhood trauma, complex trauma sequelae, social acknowledgment, and dysfunctional disclosure of trauma. The results showed that traumatic events during childhood were associated with later posttraumatic stress symptoms but with classic rather than complex symptoms. Social acknowledgment and dysfunctional disclosure partially mediated this relationship. These findings suggest that childhood traumatic stress impacts individuals across the life span and may be associated with particular adverse psychopathological consequences.

Transforming today’s energy systems in industrialized countries requires a substantial reduction of the total energy consumption at the individual level. Selected instruments have been found to be effective in changing people’s behavior in single domains. However, the so far weak success story on reducing overall energy consumption indicates that our understanding of the determining factors of individual energy consumption as well as of its change is far from being conclusive. Among others, the scientific state of the art is dominated by analyzing single domains of consumption and by neglecting embodied energy. It also displays strong disciplinary splits and the literature often fails to distinguish between explaining behavior and explaining change of behavior. Moreover, there are knowledge gaps regarding the legitimacy and effectiveness of the governance of individual consumption behavior and its change. Against this backdrop, the aim of this paper is to establish an integrated interdisciplinary framework that offers a systematic basis for linking the different aspects in research on energy related consumption behavior, thus paving the way for establishing a better evidence base to inform societal actions. The framework connects the three relevant analytical aspects of the topic in question: (1) It systematically and conceptually frames the objects, i.e. the energy consumption behavior and its change (explananda); (2) it structures the factors that potentially explain the energy consumption behavior and its change (explanantia); (3) it provides a differentiated understanding of change inducing interventions in terms of governance. Based on the existing states of the art approaches from different disciplines within the social sciences the proposed framework is supposed to guide interdisciplinary empirical research.

The private-collective innovation model proposes incentives for individuals and firms to privately invest resources to create public goods innovations. Such innovations are characterized by non-rivalry and non-exclusivity in consumption. Examples include open source software, user-generated media products, drug formulas, and sport equipment designs. There is still limited empirical research on private-collective innovation. We present a case study to (1) provide empirical evidence of a case of private-collective innovation, showing specific benefits, and (2) to extend the private-collective innovation model by analyzing the hidden costs for the company involved. We examine the development of the Nokia Internet Tablet, which builds on both proprietary and open source software development, and that involves both Nokia developers and volunteers who are not employed by the company. Seven benefits for Nokia are identified, as are five hidden costs: difficulty to differentiate, guarding business secrets, reducing community entry barriers, giving up control, and organizational inertia. We examine the actions taken by the management to mitigate these costs throughout the development period.

Institutions are one of the decisive factors which enable, constrain and shape adaptation to the impacts of climate change, variability and extreme events. However, current understanding of institutions in adaptation situations is fragmented across the scientific community, evidence diverges, and cumulative learning beyond single studies is limited. This study adopts a diagnostic approach to elaborate a nuanced understanding of institutional barriers and opportunities in climate adaptation by means of a model-centred meta-analysis of 52 case studies of public climate adaptation in Europe. The first result is a novel taxonomy of institutional attributes in adaptation situations. It conceptually organises and decomposes the many details of institutions that empirical research has shown to shape climate adaptation. In the second step, the paper identifies archetypical patterns of institutional traps and trade-offs which hamper adaptation. Thirdly, corresponding opportunities are identified that enable actors to alleviate, prevent or overcome specific institutional traps or trade-offs. These results cast doubt on the validity of general institutional design principles for successful adaptation. In contrast to generic principles, the identified opportunities provide leverage to match institutions to specific governance problems that are encountered in specific contexts. Taken together, the results may contribute to more coherence and integration of adaptation research that we need if we are to foster learning about the role of institutions in adaptation situations in a cumulative fashion.

Empirical research on discrimination is faced with crucial problems stemming from the specific character of its object of study. In democratic societies the communication of prejudices and other forms of discriminatory behavior is considered socially undesirable and depends on situational factors such as whether a situation is considered private or whether a discriminatory consensus can be assumed. Regular surveys thus can only offer a blurred picture of the phenomenon. But also survey experiments intended to decrease the social desirability bias (SDB) so far failed in systematically implementing situational variables. This paper introduces three experimental approaches to improve the study of discrimination and other topics of social (un-)desirability. First, we argue in favor of cognitive context framing in surveys in order to operationalize the salience of situational norms. Second, factorial surveys offer a way to take situational contexts and substitute behavior into account. And third, choice experiments – a rather new method in sociology – offer a more valid method of measuring behavioral characteristics compared to simple items in surveys. All three approaches – which may be combined – are easy to implement in large-scale surveys. Results of empirical studies demonstrate the fruitfulness of each of these approaches.

Einstellungen und Emotionen im Kontext der Schule spielen für das Lernen eine zentrale Rolle. Dennoch gibt es bisher eher wenige empirische Studien zu Wahrnehmungen und Bewertungen von Grundschulkindern. Insbesondere fehlen domänenspezifische Zügänge, d. h. Untersuchungen, in denen die Einstellungen der Kinder gegenüber einem bestimmten Fach analysiert werden. Im Zuge unserer Studie wurde versucht, die Einstellungen von N=165 österreichischen Grundschulkindern der Schulstufen 1-4 zum Fach Mathematik über ein Schuljahr hinweg und bis zu Beginn der nachfolgenden Schulstufen nachzuzeichnen und Veränderungen aufzuzeigen (vier Messzeitpunkte). Die Kinder wurden dabei zu ihren Fachpräferenzen in der Schule und zu ihren Bewertungen des Fachs Mathematik schriftlich befragt. Als Referenzfach diente das Fach Zeichnen, um die Ergebnisse zum Mathematikunterricht besser einzuschätzen zu können. Die Einstellungen gegenüber dem Mathematikunterricht wurden zudem mit Leistungen der Kinder (Mathematikzeugnisnoten und Rechentest) in Beziehung gesetzt. Die Ergebnisse verdeutlichen überwiegend positive Einstellungen zum Fach Mathematik, verweisen aber auch auf deren Rückgang im Verlauf des Schuljahrs, der sich weitgehend unabhängig vom Geschlecht und der Leistungen der Kinder vollzieht.

In many languages, masculine forms (e.g., German Lehrer, “teachers, masc.”) have traditionally been used to refer to both women and men, although feminine forms are available, too. Feminine-masculine word pairs (e.g., German Lehrerinnen und Lehrer, “teachers, fem. and teachers, masc.”) are recommended as gender-fair alternatives. A large body of empirical research documents that the use of gender-fair forms instead of masculine forms has a substantial impact on mental representations. Masculine forms activate more male representations even when used in a generic sense, whereas word pairs (e.g., German Lehrerinnen und Lehrer, “teachers, fem. and teachers, masc.”) lead to a higher cognitive inclusion of women (i.e., visibility of women). Some recent studies, however, have also shown that in a professional context word pairs may be associated with lesser status. The present research is the first to investigate both effects within a single paradigm. A cross-linguistic (Italian and German) study with 391 participants shows that word pairs help to avoid a male bias in the gender-typing of professions and increase women's visibility; at the same time, they decrease the estimated salaries of typically feminine professions (but do not affect perceived social status or competence). This potential payoff has implications for language policies aiming at gender-fairness.

The purpose of this study was to examine and describe the changes in physician provider workforce, before and after two regulatory changes were implemented by the Texas Workers' Compensation Commission (TWCC) in August and September of 2003: Fee schedules and the Approved Doctor's List (ADL). The number and type of physicians who participated in the program after the changes went into effect were measured and compared to projections based on natural attrition. In addition, interviews with key stakeholders were conducted regarding the program changes. ^ Collectively, this evidence suggests that physician response followed the same patterns as shown in previous research. The number of physicians who continued to participate and bill the Texas workers' compensation program decreased significantly as a result of the regulatory changes. The consequences of these changes on access and quality of care need to be documented with empirical research. The availability of physicians in the workforce is linked to access to care. The type and location of physicians who remained in the system also have impact on quality and access to care. ^

Background. Public schools are a key forum in the fight for child health because of the opportunities they present for physical activity and fitness surveillance. However, because schools are evaluated and funded on the basis of standardized academic performance rather than physical activity, empirical research evaluating the connections between fitness and academic performance is needed to justify curriculum allocations to physical activity. ^ Methods. Analyses were based on a convenience sample of 315,092 individually-matched standardized academic (TAKS™) and fitness (FITNESSGRAM®) test records collected by 13 Texas school districts under state mandates. We categorized each fitness result in quintiles by age and gender and used a mixed effects regression model to compare the academic performance of the top and bottom fitness groups for each fitness test and grade level combination. ^ Results. All fitness variables except BMI showed significant, positive associations with academic performance after sociodemographic covariate adjustments, with effect sizes ranging from 0.07 (95% CI: 0.05,0.08) in girls trunklift-TAKS reading to 0.34 (0.32,0.35) in boys cardiovascular-TAKS math. Cardiovascular fitness showed the largest inter-quintile difference in TAKS score (32-75 points), followed by curl-ups. After an additional adjustment for BMI and curl-ups, cardiovascular associations peaked in 8th-9 th grades (maximum inter-quintile difference 142 TAKS points; effect size 0.75 (0.69,0.82) for 8th grade girls math) and showed dose-response characteristics across quintiles (p<0.001 for both genders and outcomes). BMI analysis demonstrated limited, non-linear association with academic performance after adjustment for sociodemographic, cardiovascular fitness and curl-up variables. Low-BMI Hispanic high school boys showed significantly lower TAKS scores than the moderate (but not high) BMI group. High-BMI non-Hispanic white high school girls showed significantly lower scores than the moderate (but not low) BMI group. ^ Conclusions. In this study, fitness was strongly and significantly related to academic performance. Cardiovascular fitness showed a distinct dose-response association with academic performance independent of other sociodemographic and fitness variables. The association peaked in late middle to early high school. The independent association of BMI to academic performance was only found in two sub-groups and was non-linear, with both low and high BMI posing risk relative to moderate BMI but not to each other. In light of our findings, we recommend that policymakers consider PE mandates in middle-high school and require linkage of academic and fitness records to facilitate longitudinal surveillance. School administrators should consider increasing PE time in pursuit of higher academic test scores, and PE practitioners should emphasize cardiovascular fitness over BMI reduction.^

El objetivo del proyecto consiste en reconstruir molecularmente la conformación de la "Asamblea Ambiental Ciudadana de Gualeguaychú" desde sus momentos fundacionales e indagar en la demanda social elaborada por los asambleístas de Gualeguaychú en oposición a la posible instalación de dos fábricas de pasta de celulosa, y la efectiva construcción de una de ellas, en la localidad de Fray Bentos, República Oriental del Uruguay. Asimismo, se inscribe en un interés más amplio por enmarcar la lucha ambiental desarrollada por la ciudadanía de Gualeguaychú en los procesos de movilización social protagonizados, en los últimos años en nuestro país, por diversos movimientos sociales organizados en el seno de la sociedad civil en defensa de los bienes naturales y que dado su carácter novedoso, concitan cada vez más la atención de la comunidad académica. Al respecto, en este proyecto de investigación nos interesa poner en discusión los trabajos de investigación elaborados hasta el momento en torno al movimiento social ambientalista de Gualeguaychú, no sólo destacando las diferentes perspectivas teóricas construidas respecto al mismo objeto de investigación; sino que además, nos permitan definir los lineamientos específicos a seguir al momento de llevar a cabo la investigación de forma empírica.

En esta tesina presentamos los resultados de un proceso de investigación orientado a describir y analizar las influencias que tienen los mecanismos desarrollados por los trabajadores sobre la estructuración de algunas dimensiones claves del mercado de trabajo en el sector de producción de cine publicitario (PcP). La PCP se caracteriza por una modalidad de organización muy flexible y efímera, basada en proyectos individuales, que congrega a los trabajadores y recursos necesarios de forma temporaria. La transitoriedad de los proyectos plantea desafíos formidables con respeto a su coordinación y regulación en el tiempo. Sin embargo, los mismos funcionan sobre una organización permanente sustentada sobre una red de contactos sociales gestados entre los miembros. En este marco, surge nuestro interrogante acerca del papel que juegan las lógicas de los propios trabajadores en el incierto mercado de trabajo de la PCP. La perspectiva teórica adoptada en nuestro trabajo, parte de la consideración de que los mercados de trabajo son producto de construcciones sociales que se diferencian histórica y espacialmente y que por tanto, se hallan socialmente regulados por una diversidad de influencias. Por ello, hemos priorizado la investigación empírica del caso particular. Nuestro objetivo principal, ha supuesto la indagación de distintas dimensiones analíticas. Así, en primer lugar, presentamos las características socioproductivas y económicas más relevantes del sector para luego centrarnos en las cuestiones nodales de nuestro estudio que contemplaron un análisis detallado de los procesos de regulación de algunas dimensiones del mercado de trabajo, a saber: acceso, reclutamiento, calificación y movilidad. Así, esta tesina pretende ser un aporte al análisis de la dinámica de los mercados de trabajo en contextos productivos flexibles, así como una contribución al conocimiento de sectores escasamente abordados por los estudios del trabajo

Este trabajo se ocupa de caracterizar los dispositivos pedagógicos atendiendo a los modos en que las políticas y procesos de escolarización son vividos y pensados en territorio. A través de la discusión de resultados de investigación empírica que desarrollamos a lo largo de cuatro años en escuelas emplazadas en contextos de extrema pobreza urbana, intentamos describir las particulares formas en que la vida escolar es producida en estos espacios urbanos. Desde la perspectiva de los estudios de gubernamentalidad, procuramos la descripción de las formas que están asumiendo los dispositivos pedagógicos y la producción de subjetividad en territorios abyectos en los que, en el marco de las sociedades de gerenciamiento, la población ha quedado librada a su propia suerte. Propondremos una forma de leer las políticas educativas atendiendo a las formas en que son experienciadas por los sujetos en territorio.

En este artículo analizamos el papel de la escuela en la producción y reproducción de la desigualdad social, a partir de una investigación realizada en veinticuatro escuelas medias de Ciudad de Buenos Aires y las provincias de Buenos Aires, Neuquén y Salta. Centrándonos en entrevistas a directivos de las escuelas. Tomaremos como ejes de análisis la percepción de los nuevos sectores sociales que se incorporan a la escuela secundaria y el cambio de funciones educativas y la definición de horizontes para la acción escolar. Buscaremos identificar cómo aparece la desigualdad social, y debatiremos si ella no es, a su turno, producida también desde la escuela media.
