Private backgardens in cities have the capacity to enhance ecological function and connectivity. The importance of increased habitat availability was tested experimentally using microcosms with soil or with soil and vegetation added into Toronto backgardens. Local attributes of the backgardens were recorded, and within the microcosms, recruitment of seeds, plants, and winged and wingless invertebrates were recorded. Natural recruitment by all organisms was significant into the microcosms in the 20 backgardens tested. Invertebrate abundance and diversity, incidental seed recruitment, and aboveground vegetation growth was enhanced regardless of whether only bare soil was added or soil with vegetation. The number of woody plants (non-herbaceous plants with hard lignified tissues or woody parts e.g., stems and are adapted to survive from one year to the next i.e., through winter) in the backgardens predicted seed recruitment and number of plant species predicted winged invertebrate abundance. Hence, simple augmentation of private backgardens—even at an ecologically small-scale—can enhance the capacity of urban systems to provide appropriate habitats for organisms within a difficult matrix for many species.  相似文献

Changes to the ground layer in urban areas are extensive, but the effects on arthropod fauna are poorly understood. We undertook a manipulative experiment to examine the response of arthropods to small-scale variation in ground covers commonly found in urban parks and gardens in Australia. The ground covers tested were bare ground, leaf litter, woodchips and grass, with plot sizes of 3.6 m2. Epigeic arthropods were sampled with pitfall traps and Tullgren funnels over 12 months following establishment of the treatments. All epigeic arthropods were sorted to order and the ants (Hymenoptera: Formicidae), beetles (Coleoptera), millipedes (Diplopoda) and slaters (Isopoda: Oniscidea) were examined at lower taxonomic levels. Diverse arthropods rapidly colonised previously cleared plots in all four treatments and were most abundant in grass plots. The diversity of ants and beetles was significantly different in different ground covers and tended to be most diverse in grass plots. Despite the treatments providing very different microclimates, the fauna studied did not show strong selection for a particular cover type overall. The abundance of grass cover in the surrounding area may have led to the grass plots having the greatest abundance of arthropods. These results have important implications for developing effective small-scale conservation efforts for arthropods in anthropogenically modified landscapes, especially for species with poor dispersal abilities.  相似文献

Although very little research in bargaining has addressed how perpetrators should deal with the aftermath of unfair allocations, it has been proposed that an apology may help the reconciliation process. Prior research, however, only focused on whether apologies can reveal positive effects on the reconciliation process but did not focus yet on whether perpetrators are actually willing to apologize. In this paper we investigate perpetrator’s willingness to apologize for a trust violation in a bargaining setting. We hypothesized that perpetrators willingness to apologize would be a function of the extent to which the victim of the trust violation is willing to forgive. This effect, however, was expected to emerge only among those perpetrators who are low in dispositional trust. The results from a laboratory study with actual transgressions and actual apologetic behavior supported our predictions and thus emphasize an instrumental view on apologizing in bargaining situations.  相似文献

Public choice theorists have shown that choice of voting procedures may affect the outcome when more than two alternatives are on a ballot. The run-off election and the two-part ballot are two alternatives used in representation elections involving more than one union. A comparison of these alternatives under various voting strategies shows that the run-off election used by the NLRB results in fewer union wins if workers vote sincerely or if they engage in strategic behavior. The run-off procedure results in more union wins if workers seek to avoid their least-favored option or if they follow a second-best strategy.  相似文献

This article develops and empirically tests a model of the dual decision-making process employees undergo to guide their behavior during organizing campaigns and elections. The model combines principles of risk-aversion theory with more traditional views that election decisions stem from cost-benefit analyses of union representation. Previous research lacks this integrated approach to the study of election behavior. Regression analyses on a sample of approximately 16,000 certification elections strongly supported the use of risk-aversion theory to predict employees’ willingness to formally participate in elections. Furthermore, we found that time exhibited a statistically significant, negative relationship with voting participation rates, the percentage of union votes, and union victories. The results also indicated that a saturation effect may exist for delays in the election process. Financial support for this research was provided by the Syracuse University Research Fund. The authors wish to thank two anonymous reviewers for helpful suggestions that significantly improved the paper.  相似文献

中国农民的公平观念:基于村委会选举调查的实证研究   总被引:1,自引:0,他引:1  
改革开放以来,中国弥漫着一种以结果,特别是经济发展结果论是非定成败的倾向,民意调查也表明公众认为经济发展优先于政治改革。那么,在于己有利的结果、达到分配公平的结果与程序的公平之间,究竟何者对中国人的公平观更具解释力?本文通过对我们关于农村居民对村委会选举公平性的情景实验调查数据的分析来回答这个问题,发现程序特征和分配公平对公平观的影响力,数倍于于己有利的结果的影响力。这些发现表明,中国的基层政治民主化具有公民政治文化基础。  相似文献

This paper explores key Internet search trends for electoral information vis-à-vis the broader media ecology in the UK and the US. An innovative methodology is introduced that maps the informational trajectories of key election events by combining Google Trends data linked to significant news events during the campaigns. While the research found spikes of search that suggested a seemingly trivial event in the US could drive voters to search out deeper information on related policy issues, the study did not find the same phenomenon in the UK. This invites a reflection on the opportunities available to Internet users/voters in the changing informational landscape and how scholars can leverage Google Trends records to better understand how voters seek information in new and evolving media ecologies.  相似文献

The experiment described in this paper analyzes imitation in an individual learning context. It supplements the results obtained for imitation in evolutionary processes.The paper makes three main contributions. First, it provides a clear distinction between intentional imitation and genuine learning. Second, it shows that players consider more than just last period's performance when choosing imitation examples. This contrasts with the assumption in most theoretical and experimental research. Third, since the design makes imitation explicit, it allows a detailed analysis of imitation behavior, showing that players do not imitate rationally.  相似文献

This paper examines the importance of management suppression tactics on union activity in the United States. NLRB data on individual certification elections which have recently become available for the period 1972–1976 are merged with structural, demographic, and industry characteristics of the 96 largest SMSAs to ascertain the role of strategy versus structure in explaining union outcomes. The measures of election-generated membership outcomes are voter participation, the margin of pro-union votes, and union wins. Union suppression practices under study include consent elections, election delays, formal objections after unions win a certification election, elections overruled because of management unfair labor practices, elections held by management petition, and the number of unfair labor practice charges per representation election. Five of the six measures of suppression are significant determinants of some facet of union expansion after adjusting for structural characteristics of the area work force.  相似文献

This study examines factors related to the occurrence of union representation elections in four-year universities and colleges and the outcomes of those elections (i.e., whether or not faculty opt for collective bargaining). In general, the results indicate that the probability of union victory in an election depends on economic conditions, the structural characteristics of the institution, and union density in higher education. For the most part, however, such indicators of institutional vulnerability are not found to be significant determinants of election occurrences. A major implication of this study is that there is a need to investigate more thoroughly the intraorganizational processes of faculty unions with regard to the allocation of organizing resources in order to understand the spread of faculty unionism. It is also suggested that the findings of this study may cast light on the growth of unionism in other white-collar and professional sectors. The authors are grateful to James L. Perry, Jeffrey Pfeffer, Claudia Bird Schoonhoven, and an anonymous reviewer for comments on an earlier version. The research assistance of Ken Bergstrom is also acknowledged.  相似文献

Unions in the electric utility industry consistently won a greater percentage of elections between 1970 and 1989 than did unions in other industries. Several factors significantly affected union victory rates at electric utilities: when the election was held, the union involved, the size of the utility, the percent of the state’s labor force unionized, the number of eligible voters, whether the election involved multiple-unions, and whether the election was Regional- or Board-directed.  相似文献

This article focuses on the election of the so-called deputies of the Jewish people in Vil'na (Vilnius) in 1818. At the time, the Russian government perceived Jewish society as a “state within a state” with its own secret government. Russian rule tried to legalise and control that imagined government or to neutralise and repress it. The Jewish elite used these mental constructs of the Russian ruling circles and positioned themselves as the holders of the “Jewish rule,” demanding the usual prerogatives of nobility.  相似文献

This paper examines the aesthetics of remixing history at the heart of the neoliberal project of India’s image makeover as the ‘land of limitless opportunity’ for global tourists and investors. I argue that the project of remixing India’s history is predicated upon the ontological fault line of how to retain and erase the original simultaneously while shaping the new in the contemporary global. Taking the Incredible India campaign as an example, I show how the original essence of India is revealed and authenticated in the very moment of its disappearance as it is morphed in the aesthetics of the contemporary global. The post-exotic self, I further argue, is not produced by effacing the exotic past, but by condensing, accelerating and fast-forwarding it into a timeless, infinite global present. And in doing so, it also reveals the blueprint of the ongoing visual rearrangement of nation’s civilisational past in the making of new India.  相似文献

The revised theory of the model of human occupation expands the concept of volition to include volitional narrative. This paper focuses on the application of this theory of volition to a client's experience in a work program. This ethnographic case study describes the volitional narrative and life world of one client who attended the occupational therapy work based program. For fifteen months the client was the subject of narrative interviews, participant observation, videotapes and telephone contacts. The findings will illustrate how knowledge of a client's volitional narrative and life world can shed critical light on understanding treatment conflicts. Finally, the discussion will underscore how important it is for work based programs to be designed to encourage therapists to adapt their treatment approaches to maximize the opportunities to seek out the client's volitional narratives and to create meaningful experiences that are consistent with the client's life world.  相似文献

This article applies a theoretical approach that focuses on the interaction between media, politicians, activists, and citizens to investigate the influence of social media during two recent general elections in Singapore. Taking into account the combination of authoritarian governance and popular elections in this city-state, this article utilizes a mixed methods approach (i.e., a combination of statistics and virtual ethnography) to analyze four aspects of this influence. First, social media are used by the opposition parties because they are the only alternative to use in disseminating information and fostering dialogue. However, the ruling authorities use the same social media to counter the opposition. Second, social media empower the opposition by serving as efficient tools to mobilize, organize, and engage active citizens. However, compared to the traditional grassroots approach, online mobilization is not as effective as expected. Third, social media are able to change the perceptions of ordinary citizens regarding the opinion climate, which could be to either the advantage or the disadvantage of the opposition. Finally, the youngest age group (i.e., 21–30 years) was surveyed in both 2011 and 2015 to investigate their responses to these changes. Because of the complex influence of social media in Singapore, the citizens in this age group are particularly prone to being swing voters.  相似文献

Because legislation affects so many aspects of the labor market, unions have long considered the political arena to be a major battleground. This paper investigates fund raising, a primary ingredient of this political activity. Specifically, the pattern of campaign contributions from labor PACs (and corporate PACs) is explained as an interaction of supply and demand. The results suggest that the demand for funds depends on the tightness of the race, the tenure of the incumbent, and ideology. Contributors are more willing to support ideological allies, expected winners, and powerful candidates.  相似文献

The nature of the relationship between organized labor and the Democratic party — still much debated among scholars —can be usefully examined through an analysis of the role of unions in the 1998 congressional elections. Evidence drawn from a wide range of sources shows that the AFL- CIO and its affiliated unions devoted considerable financial and organizational resources to mobilizing union members and allied con-stituencies to vote for Democratic candidates. Combined with the unions' direct finan-cial contributions to campaigns, this activity made unions important players in the elections and helped project an image of potency and effectiveness in the news media and among politicians. As a result, the labor/Democrat alliance remained stronger than one would expect on the basis of union density figures alone.  相似文献
