Urbanisation is an expansive process and a majority of insects live in human-modified areas. At the same time, a decrease in pollinator species richness and abundance has recently been observed in Europe, which in turn may have serious ecological and economic consequences. This study investigates the abundance, species richness and functional traits of wild bees in urban city parks in comparison to natural areas. The aim of this research was to assess the potential conservation values of urban green areas for bees. The present study demonstrates that a large and diversified city park may be a favourable habitat for bees, comparable to the natural fauna both in terms of the number and abundance of bee species. However, the study also showed that there were differences in the occurrence of species with different functional traits in the city parks investigated and in the natural landscape.  相似文献

Theories of political emotion suggest that feelings towards an issue or candidate are often better predictors for support than attitudes or preferences. We investigate whether this conjecture also holds for more abstract political entities, such as the European Union (EU), and test whether EU citizens’ feelings toward the EU are significant predictors of their EU support. We first review existing research and provide theory-driven propositions of how positive and negative emotion may influence EU-related attitudes. Second, using multilevel regression models fitted to Eurobarometer data, we estimate how feelings toward the EU are associated with support for the EU. In line with our hypotheses, analyses show that positive emotions are positively associated with EU-support, while negative affect is negatively associated with it. Contrary to some theoretical predictions, however, these effects are not mediated by individuals’ use of EU-related information.  相似文献

Field theorists have long insisted that research needs to pay attention to the particular properties of each field studied. But while much field‐theoretical research is comparative, either explicitly or implicitly, scholars have only begun to develop the language for describing the dimensions along which fields can be similar to and different from each other. In this context, this paper articulates an agenda for the analysis of variable properties of fields. It discusses variation in the degree but also in the kind of field autonomy. It discusses different dimensions of variation in field structure: fields can be more or less contested, and more or less hierarchical. The structure of symbolic oppositions in a field may take different forms. Lastly, it analyses the dimensions of variation highlighted by research on fields on the sub‐ and transnational scale. Post‐national analysis allows us to ask how fields relate to fields of the same kind on different scales, and how fields relate to fields on the same scale in other national contexts. It allows us to ask about the role resources from other scales play in structuring symbolic oppositions within fields. A more fine‐tuned vocabulary for field variation can help us better describe particular fields and it is a precondition for generating hypotheses about the conditions under which we can expect to observe fields with specified characteristics.  相似文献

Urban community gardens offer unique social and ecological benefits in cities. However, given the dynamic nature of cities and the profound effects of variable land uses on green space provisioning for people and wildlife, investigating community gardens from a landscape perspective offers valuable insight into the functions of these spaces in terms of ecosystem services and sustainable development. In this study, we use garden locations provided by stakeholder groups and fine-scale spatial data to compare community gardens across three cities: New York City, NY, Chicago, IL, and Baltimore, MD (USA). In each city, we assess the spatial distribution of gardens and compare the natural vegetation and impervious surface cover within these gardens to the surrounding neighborhood and landscape. We then compared these cities to clarify the role of community gardens in metropolitan development. Our findings demonstrate that gardens cluster in neighborhoods in New York City and Chicago, but they are more spatially distributed across the landscape in Baltimore. The distribution of Baltimore’s community gardens is more likely to be contributing to a greater network of ecosystem services across a broader urban landscape. Moreover, at the garden scale, gardens in NYC and Chicago have more canopy cover and built infrastructure than the more herbaceous gardens in Baltimore. This suggests that our case study cities exhibit different garden typologies, histories, and potential for ecosystem services. This work provides critical insight into the typology in and around community gardens in different cities, which is useful in understanding the potential ecosystem services and planning trajectories of these cities.

We conceptualize the front end in non-assembled product development to be iterative and experiment-based, consisting of three sub-phases: informal start-up, formal idea-study, and formal pre-study. Although some key activities are shared with the front end activities in assembled product development, literature reviews, anticipating requirements of customers’ production processes, analysis of raw materials, anticipation of scale-up problems, and tests in bench-, pilot plant-, and full scale production represent unique activities. In addition, product concepts were frequently developed in parallel, requiring specification of physical, chemical and structural properties. These findings have implications for increasing the success and quality of front end efforts.  相似文献

The study was a qualitative investigation aimed at therapists' responses to working with a population of incestuous sexual abusers. Semi-structured interviews were conducted with nine therapists who were recruited from psychotherapy, psychology, and forensic psychology services in the National Health Service (NHS) in the UK. The predominant therapeutic model was psychodynamic; however, cognitive-behavioural and integrative approaches were practiced by some therapists. The data were analyzed using interpretative phenomenological analysis (Smith, 1996). Results suggested that the therapists experienced a considerable amount of negative and difficult feelings and that they tended to experience feeling controlled and deceived, which seemed to influence their ability to create and maintain the therapeutic relationship. It was suggested that the dynamics of incestuous sexual abuse played a part in these difficulties. The results are discussed with reference to the clinical therapeutic literature.  相似文献

This paper discusses the results of fusing different social work education trends in planning a relevant curriculum. These trends include a focus on practice-specific competencies, specialization of graduate programs, and the emerging role of students as consumers and evaluators of their educational experiences. Recommendations for designing processes of evaluation are offered.  相似文献

It is the aim of this paper to emphasize the antecedents leading to flexible contract arrangements in comparison to standard employment, and the effects of different contract policies especially for flexible contracting with the highly qualified workforce in knowledge-intensive firms. So far, there are contradictory findings as to what contract arrangement can be considered as advantageous in this field. Our analysis is based on qualitative fieldwork in Germany, including ten company cases. We reveal three organizational types of contract policy: One type relies on permanent employment, another on independent contracting with freelancers and a third pursues a combination of both. We identified the way of generating and protecting knowledge as an antecedent of different contract policies of organizations in knowledge-intensive fields. Another finding is that the question of gaining positive or negative effects—for both standard and flexible contracting—especially depends on the embeddedness of the contract policy in a broader set of HR practices. Our analysis adds to former studies, as it specifies that flexible contracting with an independent workforce in knowledge-intensive work environments can be pursued if there is an efficient substitution for internal control mechanisms in terms of controlling knowledge channels.  相似文献
