Urban plant biodiversity is influenced by both the physical environment and attitudes and preferences of urban residents for specific plant types. Urban residents are assumed to be disconnected from their immediate environment, and cultural and societal factors have been emphasized over environmental factors in studies of landscaping choices. However, we postulate that local climatic and environmental factors can also affect preferences for plant attributes. Therefore, spatial and temporal patterns in urban tree biodiversity may be driven not only by the direct effect of environmental variables on plant function, but also by the effect of environmental variables on attitudes toward trees and associated choices about which types of trees to plant. Here, we tested the relative effects of socio-economic and local environmental factors on preferences toward tree attributes in five counties in southern California in and surrounding Los Angeles, based on 1,029 household surveys. We found that local environmental factors have as strong an effect on preferences for tree attributes as socio-economic factors. Specifically, people located in hotter climates (average maximum temperature 25.1 °C) were more likely to value shade trees than those located in cooler regions (23.1 °C). Additionally, people located in desert areas were less likely to consider trees to be important in their city compared with people located in naturally forested areas. Overall, our research demonstrates the inherent connections between local environmental factors and perceptions of nature, even in large modern cities. Accounting for these factors can contribute to the growing interest in understanding patterns of urban biodiversity.  相似文献

Two studies examined how individual differences in social understanding influence children's information-seeking orientations during an initial meeting with a peer, in which they do or do not anticipate future interaction. Study 1 involved a relatively controlled, laboratory setting in which 7-9 year old children were presented a list of questions from which to choose what to ask the peer. The findings indicate that children who view a person's behavior in terms of stable dispositional characteristics (high SDC), express greater interest in gathering trait-related information about an unfamiliar peer than children who do not perceive people in terms of stable traits (low SDC), but only when they expect to play games with that peer in a future interaction. Study 2 involved a more naturalistic observation of the actual questions 7-9 year old children ask during an initial meeting with an unfamiliar peer. The findings showed that high SDC children asked more questions of the peer when they expected interaction than when they did not, whereas low SDC children did not differ significantly across conditions. Taken together, the two studies indicate that the future, predictability orientation of high SDC children leads to a more extensive information search about a peer when they expect interaction with that peer involving instrumental choices.  相似文献

Abstract

Recent changes to policies and funding for tertiary education are exacerbating an already difficult situation for refugees aiming to earn university degrees. No one intended to create the barriers that the refugee-background community faces; government agencies continue attempts to improve educational outcomes for those who arrive as refugees. The root causes of this situation are the complexity of the refugee situation and a lack of holistic knowledge about this diverse group of New Zealand residents among policy makers and educators. In addition, the complexity of interactions among policy changes and refugee situations has prevented any single agency from predicting outcomes of its policies for refugee-background students. In this paper, I discuss how new policies interact with a range of existing barriers faced by refugees pursuing degrees and how, without urgent attention, this will constrict or close pathways into and through university study. I further suggest that the strongest foundation for an effective program to provide equitable access to university education is including refugee-background students among those groups who receive equity consideration.  相似文献

The multidimensionality of money was investigated, using exploratory factor analysis (EFA). The respondents, 290 college students from Korea, Japan, and the United States, were administered a survey, which included socio-demographic questions, and Furnham's (1984) Money Beliefs and Behaviors (MBBS) Scale. Through a series of principal components analyses, a three-factor model with 10 MBBS items was identified. The three factors, Power, Security, and Financial Modesty accounted for 53.6% of the variance. The findings have implications for college students and financial management practitioners.  相似文献

Objective. Few researchers have investigated who lives near the worst polluting facilities. In this study, we test for disparate impact from hazardous industrial and infrastructure facilities on racial/ethnic minorities, the disadvantaged, the working class, and manufacturing workers in the nine‐county Philadelphia MSA. Methods. Hazard Scores for Philadelphia‐area facilities in EPA's Risk‐Screening Environmental Indicators (RSEI) database were calculated and facilities mapped onto Census block group maps. One‐kilometer buffer zones around facilities were created and intersected with Census data on population inside and outside buffers. After correcting for spatial autocorrelation, we tested for relationships between Hazard Scores and characteristics of people near facilities using multivariate regression. Results. Hazard Scores rose along with percents black, Hispanic, disadvantaged, and employed in manufacturing in some (but not all) counties. Conclusions. Among those living near polluting facilities, minorities, the poor, and manufacturing workers lived near the most hazardous, constituting a disparate impact on these groups.  相似文献

Audiotapes of the voices of77 preschool children were prepared. Subjects listened to the tapes, and then provided their impressions of the competence, leadership, dominance, warmth, and honesty of the children. Judgments of the voices' babyishness and attractiveness were also obtained. Perceivers reliably discriminated the children's voices along the dimensions of babyishness and attractiveness. Moreover, analyses revealed that the previously documented impact of these characteristics on first impressions of adults extends to impressions of young children. The similarity of the effects of these characteristics on impressions formed about children to those revealed for adults suggests that vocal qualities may have an impact on personality development via a process of self-fulfilling prophecy.  相似文献

Abstract Three explanations typically are offered for differences in earnings: (1) individuals have different levels of human capital and hold different jobs (endowments differ), (2) rewards to human capital and job characteristics differ (returns differ), and (3) some combination of differences in endowments and returns explain variations in earnings. We argue that the structure of labor markets in nonmetropolitan (nonmetro) areas differs from that in metropolitan (metro) areas such that returns, as well as endowments, vary. These variations in returns favor metropolitan workers, explaining the predominant portion of the metro/nonmetro earnings gap. We examine the earnings differences for metro and nonmetro men and women in both 1977 and 1987, showing that returns outweigh endowments in explaining that gap for both men and women, although their importance decreases over the ten-year period. Research to improve our understanding of how differences in labor market structure produce differential returns has begun and may yield yet another avenue for action for policymakers interested in reducing metro/nonmetro inequalities.  相似文献

Cooperative learning is a structured, systematic instructional technique in which students work together in small groups toward a common goal. We demonstrate the effectiveness of cooperative learning with an illustrative example for teaching the labor supply curve. Recommendations for introducing the technique, forming groups, the instructor's role during group work, grading and extensions of cooperative learning to other topics are discussed.  相似文献

Abstract We examine the prevalence of nonstandard employment in the nonmetropolitan United States using the Current Population Survey Supplement on Contingent Work (1999 and 2001). We find that nonstandard work is more prevalent in nonmetropolitan than in central city or suburban areas. Logistic regression models controlling for sociode‐mographic and work characteristics, show that nonmetropolitan workers experience higher odds of nonstandard employment than central city or suburban workers. Variations in industrial and occupational structures in nonmetro and metro areas do not explain residential differences in nonstandard work. We also estimate the odds of employment in each of the three components of nonstandard work: contingent work, part‐time, and varied hour work. Nonmetropolitan workers are more likely than central city and suburban workers to be employed in contingent or varied hour work. The benefits and wages of nonstandard work are lower than for standard work across residence areas. The results highlight the importance of understanding nonstandard work and the components of nonstandard work, particularly when considering the nature of work across industries, occupations, and residence.  相似文献
