The influence of land use type and municipal context on urban tree species diversity 总被引:1,自引:0,他引:1
Recent research has focused on the ways urban forest patterns vary in relation to level of urbanization and socioeconomic characteristics, with most studies limited to one urban land use type or multiple non-differentiate land uses. Additionally, the majority of studies examining urban forest patterns focus on canopy cover extent, with less attention given to patterns of species diversity. This study explores how tree species diversity varies across different urban land uses and municipal boundaries to better understand the role of land use types in shaping urban forest patterns. The goal is addressed through an exploration of plot-level tree data in the urban municipalities of Peel Region located in the Greater Toronto Area (Ontario, Canada). Species composition and standard diversity metrics are calculated for eight land use types and four municipalities. Our results show that differences in diversity metrics and species composition are greater between urban land uses than municipalities. Moreover, Peel’s urban forest has relatively high alpha diversity but many species are present on only one land use type. The results suggest that different causal processes are associated with each land use type, and that urban forest managers should adopt land use-specific strategies to meet species composition goals within the urban forest. 相似文献

Jurisdiction-stripping has long been a questionable component of Congress's power to supervise the judiciary's policymaking role. It has gained notoriety in recent debates surrounding judicial involvement in areas including religious establishment and privacy issues such as abortion and same-sex marriage. Most scholarship equates the advocacy of jurisdiction-stripping measures with symbolic position-taking that is unmotivated by the goal of traditional policy success. This work, a quantitative case study of the first such measure to pass the House of Representative since Reconstruction, seeks to isolate legislative motivations for exerting jurisdictional controls against the Supreme Court. Legislators’ votes on this measure were multifaceted. While those decisions were guided in part by the symbolic and representational considerations that traditionally underlie the advocacy of such legislation, there is also evidence more substantive motivations played a part. The study highlights the evolving objectives of jurisdiction-stripping's advocates and, more broadly, Congress's objectives vis-à-vis the courts. 相似文献

Women with female sexual problems (FSP) are more likely than unaffected women to demonstrate negative appraisals, negative affect, and avoidance of sexual activity. Research suggests affected women also experience negative affect and avoidance in response to intimate partner contact for fear it will lead to sex. This online study examined whether women with FSP (N = 157) and without FSP (N = 129) exhibited different perceptions, affective reactions, and behavioral responses to hypothetical touch occurring outside sexual activity. Women (Mage = 30.70; SD = 6.66) were randomly assigned to one of three conditions representing hypothetical interactions with their partner (affectionate, sexual, or no touch), and answered questions about their perceptions of their partner’s sexual intentions and their own anticipated negative affect and behavioral avoidance. Women with FSP reported higher perceptions of sexual intent, negative affect, and avoidance in the sexual touch condition, and higher negative affect in the affectionate touch condition, than women without FSP. Results highlight that women with FSP have more negative reactions to partners’ hypothetical affectionate and sexual touch than women without FSP. Interventions for FSP may benefit from targeting women’s perceptions, affective reactions, and behavioral reactions to partner touch when it occurs outside of explicitly sexual contexts. 相似文献

Ethnic identity is rooted in sociocultural processes, but little is known about how social interactions predict its longitudinal changes. Using data from 154 Asian American adolescents, latent profile analysis derived four typologies based on unfair treatment (i.e., discrimination, model minority stereotyping) and ethnic socialization (i.e., cultural socialization, preparation for bias, promotion of mistrust): Low Cultural Salience, High Cultural Salience with Marginalization, Culturally Prepared with Low Mistrust, and High Mistrust/Discrimination. Few gender or generational differences in profile membership were found. Positive outcomes were linked to adolescents attuned to both positive and negative experiences, Culturally Prepared with Low Mistrust, who reported increases in ethnic belonging and decreases in negative emotions. The implications for identity formation and adjustment are discussed. 相似文献

This paper evaluates economic impacts arising from the introduction of high-speed rail (HSR) between Madrid and Barcelona. Using difference-in-differences estimation we estimate an average treatment effect for provinces with stops on the HSR line of 2.4% for economic output, 3.3% for numbers of firms, and 1.1% for labour productivity. We complement our DID results with a synthetic control analysis for Lleida and Tarragona, two provinces that we argue were assigned HSR stations largely due to their incidental location. We find that both the number of firms and labour productivity are substantially higher in these provinces than in their synthetic counterparts. 相似文献

Overparenting occurs when parents engage in developmentally inappropriate involvement in their children’s lives. This topic is salient in the context of young adults attending college, as this developmental stage necessitates independent decision-making and adjustment on the part of these students. At the same time, the turbulence involved in this transition might engender parental interference and facilitation that could impact young adults’ adjustment and perceived family functioning. This study used structural equation modeling to examine overparenting, perceived interference, facilitation, student adjustment, and family functioning in 302 parent–young adult dyads. Results indicated that overparenting was associated with facilitation, but not interference. Whereas this association was negative for young adults, it was positive for parents. This pattern was also reflected in the indirect effects of overparenting on student adjustment through young adults’ versus parents’ perceived facilitation. Young adults appear to have better outcomes when they perceive their parents to be facilitating their goals. 相似文献

AbstractChild interviews form an important component of custody evaluations. Yet, research on children’s responses to questions about home life and relationships is lacking. In the present study, children (N?=?47) aged 6 to 10?years were interviewed about their daily routines and family relationships. Responses to four categories of questions were compared: open and specific questions about routines, and negative and positive aspects of family relationships. Responses were coded for amount of information, informativeness, topic pertinence, and refusals to answer. Results suggested that questions about everyday routines and relationships elicit relevant and informative responses from children. It is suggested that interviewers begin with open-ended questions regarding daily routines to structure family law interviews with children. 相似文献

Research demonstrates counselor educators often lack skills and knowledge to train counselors to become lesbian, gay, bisexual, transgender, queer and other sexualities and gender identities (LGBTQ+) competent. This study explores the process of educators integrating LGBTQ+ competencies into their professional work. Using grounded theory and situational analysis methodologies, in-depth interviews with seven LGBTQ+ competent counselor educators were conducted and analyzed. Findings suggest educators infuse personal passion for LGBTQ+ topics into their professional work, experienced discrimination and resistance across multiple domains, infuse advocacy into their work, and have a similar definition of LGBTQ+ competent counseling. Various techniques are presented to help educators infuse LGBTQ+ competency in the classroom. 相似文献

In this paper, we present an algorithm for clustering based on univariate kernel density estimation, named ClusterKDE. It consists of an iterative procedure that in each step a new cluster is obtained by minimizing a smooth kernel function. Although in our applications we have used the univariate Gaussian kernel, any smooth kernel function can be used. The proposed algorithm has the advantage of not requiring a priori the number of cluster. Furthermore, the ClusterKDE algorithm is very simple, easy to implement, well-defined and stops in a finite number of steps, namely, it always converges independently of the initial point. We also illustrate our findings by numerical experiments which are obtained when our algorithm is implemented in the software Matlab and applied to practical applications. The results indicate that the ClusterKDE algorithm is competitive and fast when compared with the well-known Clusterdata and K-means algorithms, used by Matlab to clustering data. 相似文献
