Urbanization tends to remove or isolate green areas into fragments or restrict them to narrow corridors inserted in a matrix of buildings. Nevertheless, urban green areas may act as refuges for fauna and bats are among the animals able to use such habitats. Using bioacoustics we investigated the influence of green areas on the activity of insectivorous bats in the metropolitan area of Recife, a conurbation of 4 million people in the Atlantic forest of Northeastern Brazil. Bat activity was statistically higher in green areas, based on calls (t?=?2.5298, p?=?0.0165), but not on feeding buzzes (t?=?1.8132, p?=?0.0817) or social calls (t?=??1.5551, p?=?0.1329). Several species were able to persist in an urban matrix and calls were classified into 16 sonotypes, belonging to five families (Emballonuridae, Molossidae, Noctilionidae, Phyllostomidae and Vespertilionidae). However, activity was significantly more associated with areas with vegetation, indicating that green remnants are hotspots for bat activity. Our results indicate that most insectivorous bats have a biased use of the urban landscape and the maintenance of urban green areas is essential to preserve them and the environmental services they provide. 相似文献

This article addresses the question of to what extent young people show an inclination to accept some sacrifice in their career progression in the future in order to reach a better work–family balance. Data come from a survey conducted among a sample of 2383 university students who attended three universities: University of Nairobi, University of Iceland, and Complutense University of Madrid. After building a set of indicators about career and family involvement aspirations of respondents, and after conducting a statistical and regression analysis, this research shows that young women (on average) still have a greater predisposition than young men to make sacrifices in the future in their working careers in order to achieve a better work–family balance. Moreover, having a high degree of leadership aspirations and belonging to an egalitarian household tend to reduce the inclination to sacrifice career opportunities, whereas having a high inclination to be involved in childcare in the future and having the perception of a future work–family conflict tend to increase it. Gender attitudes have a differential effect on female and male students: having traditional gender attitudes tends to increase the inclination to sacrifice career opportunities in the case of female students and reduce it in the case of male students. 相似文献

The article aims to contribute to the still relatively unexplored area of the relationship between gender and online political participation. Using two complementary methods – a representative, post-election survey of the adult Czech population and a content analysis of communication on the selected Czech political parties’ Facebook profiles during the campaign for the 2013 Parliamentary Elections – we attempt to challenge some established assumptions regarding the allegedly equalizing effect of the Internet and social media on participatory behaviour of men and women. While survey data discovered subtle yet statistically significant differences between men and women in some online expressive activities on Facebook, mainly commenting on other users’ statuses, content analysis further revealed that there are not only notable gender gaps among the Facebook users who commented on the campaign, but also differences in the tone of communication produced by the respective gender groups, with men posting more negative comments addressed to parties as well as to other Facebook users. We suggest that these results question the prevailing perception about the narrowing of the ‘gender gap’ in the online environment and call for a more nuanced methodological approach to different forms of online political expression. 相似文献

Mitochondrial defects have been related to obesity and prostate cancer. We investigated if Mexican–Mestizo men presenting this type of cancer, exhibited somatic mutations of ATP6 and/or ND3.Body mass index (BMI) was determined; the degree of prostate cancer aggressiveness was demarcated by the Gleason score. DNA from tumor tissue and from blood leukocytes was amplified by the polymerase chain reaction and ATP6 and ND3 were sequenced. We included 77 men: 20 had normal BMI, 38 were overweight and 19 had obesity; ages ranged from 52 to 83. After sequencing ATP6 and ND3, from DNA obtained from leukocytes and tumor tissue, we did not find any somatic mutations. All changes observed, in both genes, were polymorphisms. In ATP6 we identified, in six patients, two non-synonymous nucleotide changes and in ND3 we observed that twelve patients presented non-synonymous polymorphisms. To our knowledge, this constitutes the first report where the complete sequences of the ATP6 and ND3 have been analyzed in Mexican–Mestizo men with prostate cancer and diverse BMI. Our results differ with those reported in Caucasian populations, possibly due to ethnic differences. 相似文献

In this paper, we analyze the relevance of intercultural education within contemporary educational debates in Argentina. First, we will review Argentinean legislation. Then, we will discuss the core characteristics of the Argentine educational system in order to study the historical incorporation of indigenous people into the school system. Later, we will explore concrete legislation regarding intercultural education, emphasizing the potential of such legislation as well the limitations. Finally, we will present how our findings connect to the main discussions in the field of anthropology and education. 相似文献

During the last 20 years, the influx of immigrant pupils in Spanish schools has taken up much of school counsellors’ agendas. This leads us to reflect upon the status and role of educational guidance in terms of cultural diversity management, particularly focusing on two elements that may potentially help understand the situation: relations with other educational agents and the intervention model applied. The field work for this study was carried out during an academic semester in four secondary schools in Huelva. In addition to the analysis of official school documentation, remarks and field notes, semi-structured interviews were carried out and a discussion group was held with the four counsellors. Counsellors are trying to overcome an intervention model that is mainly therapeutic in nature and make space in their schedules for a way of working that is more focused on prevention and advisory services, incorporating the participation of other educational actors. But this is not an easy task. The possibility of generating changes would encourage better integration of cultural diversity in the life of schools, rather than treating it as a negative/deficit view, as an occasional issue, individual and isolated from the sum of school activities and other members of the education community. 相似文献

In this study the relationship between obesity, alcohol misuse, smoking and changes in quantity of labor supplied during an economic meltdown are examined. The data used stem from a health and lifestyle panel survey carried out by the Public Health Institute of Iceland in 2007 and 2009. Probit analysis was used to assess if pre-crisis body weight, alcohol misuse or smoking were related to subsequent job-loss or a reduction in hours worked following the 2008 economic collapse in Iceland. Results indicated that body weight, alcohol misuse and smoking are related to reductions in quantity of labor supplied for females only. Female body mass index was positively related to the probability of a reduction in quantity of labor supplied, while alcohol misuse and smoking were negatively related to the probability of decreasing hours worked for females. 相似文献

Nowadays, with an increasingly aging population, an increasing proportion of the population on disability benefits, and an
implicitly lower level of economic output and foregone tax revenue, disability has become a major public policy issue in many
countries. Estimating both single risk and competing risks models on a Swedish longitudinal database, this study analyzes
the risk of exit from the labor market due to disability at a certain age, conditional on having remained in the labor force
until that age. The explanatory variables did not have identical coefficients across destination types. For example, the estimated
single risk model shows that a higher level of education decreased the hazard of exiting the labor market with a disability
pension, while the estimated competing risks model suggests that a higher level of education increased the hazard of exiting
with a partial disability pension, but it decreased the hazard of exiting with a full disability pension.

In this paper, we examine the association between contact with migrant populations and support for the populist radical right (PRR) in Switzerland. Building on group threat and intergroup contact theories, which offer opposing predictions, and drawing on Appadurai’s thesis of the ‘fear of small numbers’, we propose a new theoretical framework to explain this association. We predict that the relationship between the size of the migrant populations and PRR voting is nonlinear: a small but noticeable minority triggers the formation of anti-immigrant attitudes, which soften as the minority grows and people start having meaningful interactions with foreigners. To test these theories, we combine individual-level data with municipality-level information. Mixed-effects multilevel models confirm that individuals in municipalities with a moderate proportion of foreigners are more likely than those with fewer or a greater number of migrants to cast their vote in support of PRR parties; this is particularly so for certain stigmatised minorities. We further explore the effect of perceived immigrant threat in moderating these relationships. 相似文献

The purpose of this study was to examine the impact of immigration legislation on Latino immigrants within the social determinants of health framework to understand the impact of such legislation on the immigrant’s health. While the socio-political climate in California is geared towards more pro-integration immigration policies, findings indicate that immigrants still experiences poor treatment in the form of microaggressions, horizontal discrimination, and institutional discrimination. This poor treatment may be an indication of residual anti-immigrant sentiment that remains in the state as well as a spillover effect from the anti-immigrant legislation being passed in neighboring states or national rhetoric. The findings overlap with four domains of the social determinants of health framework including economic stability, education, health and access to care, and social and community context. Implications for practice, policy and research are discussed. 相似文献
