This study examined the relationship between friendship representation and internalizing and externalizing problems in school-aged children. One hundred Caucasian 6–7 year-old children (50 males and 50 females) and their mothers took part in the study. The Draw-a-Man Test, the Pictorial Assessment of Interpersonal Relationships, and the Child Behavior Checklist (CBCL/6-18) were used. Children with internalizing problems, externalizing problems, comorbid internalizing and externalizing problems, and a control group were compared on their pictorial representations of friendship. Results showed that children with externalizing problems included more pictorial indices of each friend's autonomy and a larger imbalance of importance between them; children with internalizing problems drew themselves as less similar to their friends. In conclusion, children's pictorial representation allows exploring some aspects of their tacit knowledge about the relationship with a best friend, which is not easily expressed verbally by young children. Finally, the implications of these findings for theoretical and empirical research development on friendship are discussed. 相似文献

A macro-scale methodology for vehicle emissions estimation is described. The methodology is based on both correlations between
activity level and PM, CO, THC and NO
x
vehicle emissions and relationships between demographic and socio-economic variables and transportation activity level. First,
pollutant emissions were correlated with transportation activity, expressed as vehicle-km/year, using existing data collected
from mobile sources emission inventories in nine urban cities of Chile. Second, demographic and socio-economic variables were
pre-selected from those that could intuitively be correlated with vehicle activity level and considering the data availability.
Using the individual R
2 correlation coefficient as variable selection criterion, population, the number of vehicles, fuel consumption, gross domestic
product, average family incomes and road kilometers were finally chosen. A different set of explicative variables was considered
for different vehicle categories, based on the selection criterion above mentioned. Then, correlation functions between these
variables and transport activity were obtained by non-linear Gauss–Newton least square method. This methodology was applied
to eighteen provinces of the country obtaining total annual emission for mobile sources, divided into six main vehicles categories. 相似文献

ABSTRACT Several studies have highlighted the relationship between internalized sexual stigma (ISS) and dissociation. The aim of the present study was to empirically investigate this relationship through a quantitative study. The Measure of Internalized Sexual Stigma for Lesbians and Gay Men (MISS-LG) and the Dissociation Scale (DIS) of the Trauma Symptom Inventory (TSI) were administered to 120 Caucasian participants who self-identified as gay men. Findings suggested that dissociative symptomatology, as measured by DIS—an estimation of the use of dissociation as a defense mechanism—was positively associated with MISS general index and all dimensions of MISS, especially the sexuality dimension (ISS-S). Moreover, the effect of the ISS-S on DIS was amplified in Catholic participants, suggesting a moderating role of religiosity. Implications for future research and clinical practice are discussed. 相似文献

We develop an extension of Luce's random choice model to study violations of the weak axiom of revealed preference. We introduce the notion of a stochastic preference and show that it implies the Luce model. Then, to address well‐known difficulties of the Luce model, we define the attribute rule and establish that the existence of a well‐defined stochastic preference over attributes characterizes it. We prove that the set of attribute rules and random utility maximizers are essentially the same. Finally, we show that both the Luce and attribute rules have a unique consistent extension to dynamic problems. 相似文献

Evaluation of performance of European cities with the aim to promote quality of life improvements 总被引:2,自引:0,他引:2
This paper explores the possibilities presented by DEA to assess quality of life and evaluate the performance of city managers in what concerns the promotion of urban quality of life. Using the data provided by the Urban Audit program, from the European Union, we defined the city profile regarding quality of life for 206 cities. Two approaches are presented: the construction of a composite indicator of quality of life and the assessment of local management performance, contextualised by the GDP per capita to measure the ability of local authorities to promote quality of life given the economic condition of the country. The results identify the cities with urban best practices and present a model of intervention for the cities considered inefficient, based on benchmarking principles. 相似文献

Based on a literature review, this article frames different stages of the foster care process, identifying a set of standardized measures in the American and Portuguese contexts which, if implemented, could contribute towards higher levels of foster success. The article continues with the presentation of a comparative study, based on the application of the Casey Foster Applicant Inventory-Applicant Version (CFAI-A) questionnaire, in the aforementioned contexts. Taking a comparative analyses of CFAI-A's psychometric characteristics in four different samples as a starting point, one discovered that despite the fact that the questionnaire was adapted to Portuguese reality, it kept the quality values presented on the American samples. It specifically shows significant values regarding reliability and validity. This questionnaire, which aims to assess the potential of foster families, also supports the technical staff's decision making process regarding the monitoring and support of foster families, while it also promotes a better decision in the placement process towards the child's integration and development. 相似文献

In this paper, we predict that venture capital (VC) backed initial public offerings (IPOs) will attract more attention than non-VC-backed IPOs, as VCs offer important signals to investors searching for information about entrepreneurial firms. We use a measure developed by Google (i.e., Trends) to capture the spikes in investors' attention experienced by firms in the time period surrounding their IPOs. Our results demonstrate that firms backed by VCs enjoy a far greater spike in attention than their counterparts. Furthermore, we find that firms with more prominent VCs, a larger number of VCs, and VCs situated at farther geographic distances exhibit significantly greater spikes in investors’ attention during the week of their IPO. Combined, the findings show a clear demarcation between entrepreneurial firms with or without VC backing, they bring to the fore new upshots stemming from the relationship between VCs and entrepreneurial firms, and they raise new potential questions on this relationship and beyond. 相似文献

Academic and corporate interest in reverse logistics (RL) has risen considerably in recent years. In this context, the objective of this study was to identify the drivers that enable RL practice in an emerging economy. Firstly, international peer-reviewed publications on RL were used to develop a RL environment framework representing the main RL internal and external influences. Secondly, a case-based research was conducted in a large manufacturing company located in Southern Brazil. The results indicated that the most cited driver in the RL literature, the government and legislation, was not a main influence on the studied company. Environmental legislation is still limited in the country and struggles to provide incentives to increase materials recycling. An economic factor related to materials value recovery was also found to drive the backward flow. Finally, knowledge of the RL driving forces may support industries to better implement and manage reverse flows and to bridge the gap between existing and future solutions for reverse supply chains. 相似文献
