Verbreitung der Direktsaat in der Schweiz

Direktsaat ist eine wirksame Erosionsschutzmassnahme, die diverse ökologische und ökonomische Vorteile aufweist. Sie gewann in der Schweiz in den letzten Jahren zunehmend an Bedeutung: Seit Mitte der 1980er hat die direkt gesäte Fläche von wenigen Hektaren auf rund 12'000 ha im Jahre 2006 zugenommen. Gemessen am gesamten Ackerland ist diese Fläche aber nach wie vor gering (3 %). Regional kann die Direktsaat jedoch beachtliche Anteile aufweisen. Die in diesem Artikel vorgestellten Karten geben einen nationalen Überblick über die räumliche Verbreitung der direkt gesäten Fläche im Jahr 2006. Als Datengrundlage diente eine im Winter 2006 / 07 durchgeführte Befragung von Landwirten und Lohnunternehmern. Die Karten zeigen sehr heterogene Muster, machen aber auch verschiedene Schwerpunktregionen sichtbar. Die Interpretation dieser Muster veranschaulicht, dass die Verbreitung der Direktsaat an eine Vielzahl von Faktoren gebunden ist und nicht nur anhand naturräumlicher Gegebenheiten erklärt werden kann. Kantonale Förderprogramme spielen dabei eine ebenso wichtige Rolle wie das persönliche Engagement der beteiligten Experten und Lohnunternehmer, bestehende landwirtschaftliche Netzwerke sowie die Lebenswelten der Landwirte

Perceived Interparental Conflict and Early Adolescents' Friendships: The Role of Attachment Security and Emotion Regulation

Although there is strong evidence for the effect of interparental conflict on adolescents' internalizing and externalizing problems, little is known about the effect on the quality of adolescents' relationships. The current study investigates the link between adolescents' friendships and interparental conflict as reported by both parents and adolescents. It considers early adolescents' emotion regulation ability and attachment security as mediators. The analysis is based on a longitudinal study with two waves separated by 12months. The participants were 180 two-parent families and their adolescent children (50.5% girls), the average age of the latter being 10.61years (SD=0.41) at the outset (Time 1). Binomial logistic regression analysis revealed that perceived interparental conflict increased the risk of instability in friendship relationships across the 1-year period. Structural equation modeling analysis indicated that the association between perceived interparental conflict and friendship quality was mediated by emotion regulation and attachment security. The discussion focuses on mechanisms whereby interparental conflict influences early adolescents' friendship relationship

Social Learning Processes in Swiss Soil Protection—The ‘From Farmer - To Farmer' Project

Social learning approaches have become a prominent focus in studies related to sustainable agriculture. In order to better understand the potential of social learning for more sustainable development, the present study assessed the processes, effects and facilitating elements of interaction related to social learning in the context of Swiss soil protection and the innovative ‘From Farmer - To Farmer' project. The study reveals that social learning contributes to fundamental transformations of patterns of interactions. However, the study also demonstrates that a learning-oriented understanding of sustainable development implies including analysis of the institutional environments in which the organizations of the individual representatives of face-to-face-based social learning processes are operating. This has shown to be a decisive element when face-to-face-based learning processes of the organisations' representatives are translated into organisational learning. Moreover, the study revealed that this was achieved not directly through formalisation of new lines of institutionalised cooperation but by establishing links in a ‘boundary space' trying out new forms of collaboration, aiming at social learning and co-production of knowledge. It is argued that further research on social learning processes should give greater emphasis to this intermediary level of ‘boundary spaces

Does a Brief Mindfulness Training Enhance Heartfulness in Students? Results of a Pilot Study

(1) Background: There is robust evidence that mindfulness trainings enhance mindfulness as operationalized in Western psychology, but evidence about their effect on aspects of heartfulness is sparse. This study seeks to test whether a brief mindfulness training enhances heart qualities, including self-compassion, gratitude, and the generation of feelings of happiness. (2) Methods: Eighteen students enrolled in a mindfulness training that was offered as part of an interdisciplinary class. The training consisted of five training sessions and four booster sessions of 45 minutes each over the course of nine weeks. Mindfulness was measured with the Five Facet Mindfulness Questionnaire-Short Form (FFMQ-SF) and self-compassion was measured with the Self-Compassion Scale Short Form (SCS-SF). In addition, two items were drawn from the Caring for Bliss Scale (CBS) measuring gratitude and the generation of feelings of happiness in the present moment. Assessments were conducted before the training (pre), after the training (post), and four weeks after the training (follow-up). (3) Results: Results showed that mindfulness, general self-compassion, and generating feelings of happiness increased from pre to post, whereas self-critical attitudes decreased and that these changes were maintained at follow-up. Gratitude increased from pre to post and then decreased from post to follow-up. (4) Conclusions: A brief mindfulness training seems to be beneficial for students to improve mindfulness and aspects of heartfulness, but further research is needed to investigate the effectiveness of the training relative to a cohort or active control group

Associations Between Relationship Maintenance Behaviors and Marital Stability in Remarriages

Nearly half of adults in the U.S. indicated they had a close step-relative that included stepparents, stepchildren, and other close relationships. The prevalence of stepfamilies is rapidly increasing and represents a population that remains largely understudied. This study explored the roles of socioemotional behaviors (positivity, negativity, and sexual interest) on marital stability for different remarriage constellations (depending on which of the couple, both partners, or neither had previous children). This study uses dyadic relationship data from 879 couples. It was hypothesized that positivity and sexual interest would be inversely related to marital instability, while negativity will be correlated with marital instability

Perceived interparental conflict and early adolescents' friendships : the role of attachment security and emotion regulation

Erworben im Rahmen der Schweizer Nationallizenzen (http://www.nationallizenzen.ch)Although there is strong evidence for the effect of interparental conflict on adolescents’ internalizing and externalizing problems, little is known about the effect on the quality of adolescents’ relationships.

Assessing associations in multi-member multi-group data: An actor-partner interdependence

Data from groups often have a multimember multigroup (MMMG) structure. Examples are two-parent families with a female or male child (three members, two groups), two same-gender and opposite-gender peers of different status (two members, four groups), or gay, lesbian, and heterosexual couples (two members, three groups). To analyze such data, a framework called MMMG actor – partner interdependence model (MMMG APIM) is presented considering group composition. Three models are discussed in detail: the three-member two-group APIM, the two-member four-group APIM, and the two-member three-group APIM. Structural equation modeling and cross-sectional and longitudinal data are used to illustrate the approach. To ease the interpretation of APIM findings, a proposal of a general classification scheme is made

Participatory Assessment and Adaptation for Resilience to Climate Change

Traditional monitoring and evaluation tools are often costly and are not well placed to assess complex, multi-dimensional dynamic livelihood attributes, such as resilience. While these approaches may be accurate in measurement, they often fail to empower respondents to take action. Drawbacks of other participatory resilience approaches include a requirement for a large amount of information, significant time required to administer surveys, and data analysis burdens (Schipper and Langston 2015, 19; COP 2016). They also need a baseline and an end line to assess change. They typically fail to capture how farmers actively address specific shocks and stresses or what lessons can be learned. Given these limitations, an opportunity exists to review alternative approaches and develop different tools. Our approach and tool, farmbetter, attempts to build on lessons learned from developing and implementing these tools. Rather than characterizing the user as lacking agency in a challenging environment, farmbetter helps users make conscious decisions to adapt and withstand specific shocks and stresses such as floods, drought, or conflict, which can require contradictory coping strategies. We aim to then further connect farmers whose properties have similar agro-ecological conditions and challenges to better facilitate knowledge-sharing between food producers, ultimately improving learning and resilience. This allows for the connection of big data with (traditional) knowledge and competences already being used by farmers to improve resilience. This is enabled by advances in technology (e.g. mobile phone availability), which offer new opportunities to more easily and cheaply collect data as well as giving access to marginalized groups’ views and knowledge (e.g. Raghavan et al. 2016)

Charge carrier transfer in the gas electron multiplier at low gas gains

Connected to the Linear Collider project TESLA at DESY, studies on the readout of TPCs based on the GEM-technology are ongoing. For particle identication via dE/dx - measurement, a good energy resolution is indispensable, and therefore losses of primary electrons have to be avoided. It turned out, that in the GEM transverse diffusion inside or close to the holes is a not negligible reason for these losses. For Ar-CH4 90:10 and TPC-like field configurations it was found, that when operated in normal amplification mode, the Standard Geometry GEM should not lose primaries, whereas for low gains, also when operated in magnetic fields up to 5T, a GEM with larger pitch and hole diameter would be necessary
