This article examines black-white residential segregation in micropolitan areas across the South. Micropolitan areas are newly defined urban clusters with a core population that ranges from 10,000 to 50,000. By shifting the focus to the nonmetropolitan South, we take debates about the “American dilemma” back to a historically important terrain of black-white relations that few scholars have systematically examined in the post-Civil Rights era. Using the most recent census, we find that the dynamics of residential segregation in our sample of micropolitan areas reflect both important opportunities and constraints. In contrast to their counterparts in metropolitan areas, blacks in the nonmetropolitan South face “only” moderate levels of segregation. Surprisingly, southern micropolitan areas afford greater opportunities for spatial assimilation to the least economically advantaged blacks as well as those who are more advantaged. Perhaps most importantly, this finding holds for micropolitan areas located in the historic Black Belt as well as elsewhere; however, several patterns emerge that suggest a set of barriers to spatial assimilation similar to those facing African Americans in metropolitan areas. In sum, our analysis clarifies the complexities of black-white segregation in the “New South/Old South,” pushing scholars to more systematically map the distinct trajectories of “American Apartheid” across time and place in the United States. 相似文献

BackgroundThere is no Australian data on the characteristics of women who consult with midwives.AimTo determine the profile of women who consult midwives in Australia.MethodsThis cross-sectional research was conducted as part of the Australian Longitudinal Study on Women's Health (ALSWH). Participants were the younger (31–36 years) cohort of the ALSWH who completed a survey in 2009, and indicated that they were currently pregnant (n = 801). The main outcome measure was consultation with a midwife.FindingsOf the 801 women who indicated that they were currently pregnant at the time of the survey, 19%, 42%, and 70% of women in the first, second and third trimesters respectively had consulted with a midwife. Women were more likely to consult a midwife if they: also consulted with a hospital doctor (OR = 2.70, 95% CI: 1.66, 4.40); also consulted with a complementary and alternative medicine practitioner (OR = 1.94, 95% CI: 1.25, 3.03); were depressed (OR = 1.84, 95% CI: 1.03, 3.28); constipated (OR = 1.80, 95% CI: 1.04, 3.13); or had been diagnosed or treated for hypertension during pregnancy (OR = 2.78, 95% CI: 1.27, 6.09). Women were less likely (OR = 0.34, 95% CI: 0.21, 0.56) to consult with a midwife if they had private health insurance.ConclusionWomen were more likely to consult with midwives in conjunction with consultations with hospital doctors or complementary and alternative medicine practitioners. Women with private health insurance were less likely to consult midwives. More research is necessary to determine the implications of the lack of midwifery care for these women. 相似文献

OBJECTIVE: The authors' purpose in this study was to estimate prevalence and correlates of Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV), major depressive episodes (MDEs) among Spanish university students. PARTICIPANTS AND METHODS: In October and November 2004, interviewers administered a screening tool to a sample of 554 students aged 18-34 years (65.9% women). RESULTS: The prevalence of MDEs was 8.7% (95% confidence interval = 6.5%-11.3%). The most common symptoms were depressed mood (81.3%) and altered sleep (79.2%). MDEs were more prevalent among women than men (p < .05). The mean number of previous episodes of depression among currently depressed students with previous episodes was 2.2 (SD = 1.4). Of depressed students, 0.6% had considered suicide and 0.2% had attempted suicide. CONCLUSIONS: Depression was highly prevalent among university students. The results suggest the need to develop some type of program or service for university students with the aim of preventing depression and improving their adaptation to university life. 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

Although theoretical foodweb models predict the presence of only three to four trophic categories, estimation of “potential”
vertical foodweb structure from species lists and inferred feeding interactions suggest that as many as 7 trophic categories
can occur in the pelagic foodwebs of North American glaciated lakes. A compilation of data on the nitrogen isotopic composition
of zooplankton from 46 Canadian Shield lakes suggested the average existence of one “realized” trophic category in addition
to that of filter-feeding, herbivorous cladocerans. When phytoplankton, planktivorous invertebrates, and plantivorous and
piscivorous fish are included, the vertical foodweb structure in the pelagic zones of these lakes are greater than those hypothesized
from some theoretical models. 相似文献

This study aimed to examine the gender-related differences in demographics, gambling measures, psychological functioning,
and motivation for therapy in an outpatient sample of pathological gamblers seeking treatment. Participants in this multisite
study included 103 adult outpatients (51 women and 52 men) meeting current DSM-IV-TR criteria for PG. Logistic regression
was used to examine if gender was related together to categorical and continuous independent variables. Female gamblers were
older than men and more likely to be divorced or widowed and to have a lower annual income. Women became more dependent on
bingo and men on slot machines. Gambling motivation and the course of illness for both sexes were also different. Female gamblers
were more anxious and with a poorer self-esteem than male gamblers and more affected by depressive symptoms; in turn, men
were more impulsive and higher sensation seekers than women and more affected by drug/alcohol abuse. The 68.6% of female gamblers
reported being victims of intimate partner violence. There were no gender differences about the motivation for treatment.
Future research should examine gambling behaviors and psychological functioning and suggest treatment approaches to address
specific goals according to these gender-related differences. 相似文献

Research has shown that women commonly hold positions of leadership within nonprofit organizations, while men typically hold the leadership positions within for-profit organizations. However, little research on women's leadership roles has been conducted within European Union countries. The purpose of this article is to examine women's leadership positions within nonprofit and for-profit organizations within the European Union and, using Hofstede's Cultural Dimensions Theory, to further investigate a potential correlation between national culture and female leadership. Fifty-one companies were examined based on type, country characteristics and gender dominance. A significant difference was found between organization type (nonprofit/for-profit) and organizational dominance (masculine/feminine). The findings suggest that the European Union has patterns of gendered leadership positions similar to patterns found previously in the USA. However, countries that were characterized as feminine had more than expected nonprofit organizations, while masculine countries had more for-profit organizations. 相似文献

This study analysed, from a social justice perspective, how students from two Chilean public schools evaluate, legitimise and delegitimise processes and social actors associated with classroom well-being. Using a participatory qualitative design, fifty-nine (59) seventh grade students were asked to take and then select photographs about their school experience, and later participated in semi-structured interviews and a group workshop. Findings regarding the classroom context showed that children legitimised active learning methodologies, teachers to whom they feel close, and the use of technology for learning. They delegitimised punishment and teachers who ignored minority students or those with learning difficulties. 相似文献

We introduce a new centrist or intermediate inequality concept, between the usual relative and absolute notions, which is
shown to be a variant of the α-ray invariant inequality measures in Pfingsten and Seidl (1997). We say that distributions
x and y have the same (x, π)-inequality if the total income difference between them is allocated among the individuals as follows: 100π% preserving
income shares in x, and 100(1−π)% in equal absolute amounts. This notion can be made as operational as current standard methods in Shorrocks
(1983).

This paper presents a study carried out in Spain that followed up 260 young people, the majority of them adults, who had been in residential care for significant periods. The follow‐up takes place between 1 and 9 years after participants had left residential care, and assesses their level of social and work integration, as well as considering the incidence of problems related to marginalization and social exclusion. Furthermore, it analyses the reasons for the child being taken into care, the socio‐family context, length of stay, changes in placement and other features or incidents in relation to the residential care. The data show that close to 15% have serious problems (drug dependence, delinquency, etc.), 25% receive help from the social services and the rest manage independently to a greater or lesser extent. We discuss the significance of these data, especially the relationship between the final result and the initial and process variables. 相似文献
