Urban green spaces, such as forest fragments, vacant lots, and community gardens, are increasingly highlighted as biodiversity refuges and are of growing interest to conservation. At the same time, the burgeoning urban garden movement partially seeks to ameliorate problems of food security. Arthropods link these two issues (conservation and food security) given their abundance, diversity, and role as providers of ecosystem services like pollination and pest control. Many previous studies of urban arthropods focused on a single taxon (e.g. order or family), and examined either local habitat drivers or effects of landscape characteristics. In contrast, we examined both local and landscape drivers of community patterns, and examined differences in abundance, richness, and trophic structure of arthropod communities in urban forest fragments, vacant lots, and community gardens. We sampled ground-foraging arthropods, collected data on 24 local habitat features (e.g., vegetation, ground cover, concrete), and examined land-cover types within 2 km of 12 study sites in Toledo, Ohio. We found that abundance and richness of urban arthropods differed by habitat type and that richness of ants and spiders, in particular, varied among lots, gardens, and forests. Several local and landscape factors correlated with changes in abundance, richness, and trophic composition of arthropods, and different factors were important for specific arthropod groups. Overwhelmingly, local factors were the predominant (80 % of interactions) driver of arthropods in this urban environment. These results indicate that park managers and gardeners alike may be able to manage forests and gardens to promote biodiversity of desired organisms and potentially improve ecosystem services within the urban landscape. 相似文献

Child gender may exert its influence on development, not as a main effect, but as a moderator among predictors and outcomes. We examined this notion in relations among toddler fearful temperament, maternal protective parenting, maternal accuracy in predicting toddler distress to novelty, and child social withdrawal. In two multi‐method, longitudinal studies of toddlers (24 months at Time 1; Ns = 93 and 117, respectively) and their mothers, few main effect gender differences occurred. Moderation existed in both studies: only for highly accurate mothers of boys, fearful temperament related to protective parenting, which then predicted later social withdrawal. Thus, studying only main‐effect gender differences may obscure important differences in how boys and girls develop from fearful temperament to later social withdrawal. 相似文献

We assessed linkages of mothers' emotion coaching and children's emotion regulation and emotion lability/negativity with children's adjustment in 72 mother–child dyads seeking treatment for oppositional defiant disorder (ODD). Dyads completed the questionnaires and discussed emotion‐related family events. Maternal emotion coaching was associated with children's emotion regulation, which in turn was related to higher mother‐reported adaptive skills, higher child‐reported internalizing symptoms, and lower child‐reported adjustment. When children were high in emotion lability/negativity, mothers' emotion coaching was associated with lower mother and child reports of externalizing behavior. Results suggest the role of emotion regulation and emotion lability in child awareness of socio‐emotional problems and support the potential of maternal emotion coaching as a protective factor for children with ODD, especially for those high in emotion lability. 相似文献

In the absence of a bilateral agreement for the portability and totalization of social security contributions between the United States and Mexico, this article examines the access to pension and health insurance benefits and employment status of older Mexican return migrants. We find that return migrants who have spent less than a year in the United States have a similar level of access to social security benefits as non‐migrants. Return migrants who have spent at least a year in the United States are less likely to have public health insurance or social security benefits, and could be more vulnerable to poverty in old age. These results inform the debate on a bilateral social security agreement between the United States and Mexico to improve return migrants' social security. 相似文献

Sexual harassment studies that use hypothetical situations and retrospective surveys may overestimate the degree to which victims actually confront their harassers. The result is that immediate emotional reactions are little understood and victims are often taken to task for nonconfrontational behavior. To address this neglect, we describe our experimental investigation of immediate reactions to sexually harassing questions encountered during a realistic job interview. Behavioral and emotional responses are compared to those in an imagined harassing interview. Results indicate that interviewees who are actually harassed react very differently than those who only imagine their responses. For example, imagined victims anticipate feeling angry but actual targets report being afraid. Anticipated behavior also did not mesh with actual behavior. Implications of these discrepancies for perceptions of correct ways to respond to harassment are examined. 相似文献

Families with disabled children run a great risk of being poor. Although policies providing poor families with financial benefits should be effective in reducing poverty, the actual effectiveness is often jeopardized by the issue of non‐take up (NTU). Yet, NTU of benefits aimed at disabled children is for the most part uncharted territory. In this article, we fill this gap using a mixed‐methods approach to (a) estimate the magnitude and characteristics of NTU in the Belgian “supplemental child benefit” by drawing on a large‐scale administrative dataset on childhood disabilities and (b) explore the determinants of NTU by means of semistructured interviews with experts and parents. We estimate an NTU rate of at least 10%, a substantial figure given that the benefit is not income tested. This mainly concerns children with “less visible disabilities” (autism spectrum disorder and other intellectual and psychological disorders) and results from insufficient information provision about the benefit's existence and eligibility criteria; process costs, for instance, the complexity of the procedure; and the way the scale to assess a child's disability is constructed. 相似文献

The present study investigated bidirectional relations between peer victimization and internalizing symptoms, with a focus on three forms of victimization (physical, verbal, relational) and two types of internalizing symptoms (depressive, anxious). In the fall and spring, children (N = 1,264–1,402 fourth and fifth graders depending on time point and data source) reported on their victimization, and teachers reported on children’s depressive and anxious symptoms. In a model including the broad constructs of victimization and internalizing symptoms, bidirectional relations emerged, with earlier victimization predicting increases in later internalizing symptoms and earlier internalizing symptoms predicting increases in later victimization. These bidirectional relations did not hold in two additional models, the first of which included the three forms of victimization and internalizing symptoms and the second of which included victimization and the two types of internalizing symptoms. Rather, results of the first model suggested that earlier internalizing symptoms predicted later physical, verbal, and relational (marginal) victimization, and the second model did not fit the data well. Findings are discussed in terms of implications of bidirectional relations between victimization and internalizing symptoms. 相似文献

The present study tested for gender differences in depression and body image among a sample of 6th–8th grade low-income African American adolescents. Gender differences were found, with adolescent girls more likely to report both depressive symptoms and poor body image. The most frequently endorsed body image concern for both boys and girls was the desire to lose weight, with approximately half of the girls in this sample reporting they would like to lose weight. Results of mediational analyses indicate that poor body image mediates the relation between gender and depression in this sample, suggesting that heightened rates of depression, among girls, are due to heightened rates of poor body image. 相似文献
