This work proposes a methodological approach to redistribute population data obtained from polygonal census tracts into population density surfaces (grids) based on a cell space database. The methodology was first developed for the municipality of Marabá, Pará state, in the Brazilian Amazon. We used a dasymetric method to eliminate areas of environmental restriction to human presence; then integrated environmental data indicative of human presence to generate a potential surface of population occurrence; and finally, census population count data were redistributed into cells. The methodology was subsequently adapted for 13 municipalities of the Sustainable Forests District (SFD) of BR-163, generating population distribution surfaces for 2000 and 2007. The evolution of the resident population over the SFD-BR163 showed spatial patterns compatible with the occupation process described in the literature and verified by fieldwork. To be applied over other areas, the proposed methodology must be adapted with local parameters but in this way, population density surfaces can be useful as an additional data source to study population and environment relationships.  相似文献

International Migration and the Role of Remittances in Eastern Europe   总被引:3,自引:0,他引:3  
In this paper we analyse the effect of remittances on employment performance for Central and East European (CEE) economies. We show that the impact of remittances on unemployment depends on its effect on productivity growth and investment. In order to empirically analyse the impact of remittances we estimate a productivity equation using a set of 11 transition countries during the 1990 to 1999 period. Our results show support for the view that remittances have a positive impact on productivity and employment both directly and indirectly through its effect on investment.  相似文献

There is a glaring lack of data to inform culturally appropriate HIV prevention interventions targeting environments such as bathhouses where men who have sex with men (MSM) practice sexual risk behaviors. This study compares sexual behavioral patterns across two bathhouse sites in order to identify important themes to address when tailoring HIV prevention interventions to bathhouse environments. We analyzed semi-structured interviews with workers and patrons at two bathhouses to explore similarities and differences. A coding scheme was established and data were organized according to conceptual themes. We found that differences between the two sites emerged in six key areas: bathhouse clientele, attraction to particular sites, sexual practices and condom use, communication about sex and HIV status, bathhouse rules, and substance use. Implications for HIV prevention intervention policy are discussed.  相似文献

A number of scientists have recently conducted research that shows that tropical cyclone intensity is likely to increase in the future. This would result in an increase in the damage along with a decrease in economic productivity due to precautionary cessation of the economic activity of the affected areas during the passage of the cyclone. The economic effect of this stop in economic activity is a phenomenon that has not received much attention in the past, and the cumulative effect that it can have on the Japanese economy over the next 75 years has never been evaluated. The starting point for the evaluation of the economic risks is the change in the patterns of tropical cyclone intensity suggested by Knutson and Tuleya.( 1 ) The results obtained show how a significant decrease in the overall productivity of the country could be expected, which could lower GDP by between 6% and 13% by 2085.  相似文献

This study tests an add-on procedure to foster change in Career Construction Counseling by eliciting reconceptualization innovative moments. After the career counseling intervention with 42 participants, 21 participants were allocated to the add-on procedure, consisting of two additional sessions focused on eliciting reconceptualization innovative moments In turn, participants in the comparison group attended two extra intervention sessions in which the lifetime task was used. Outcome measures assessing vocational behavior and psychological distress were applied at the onset, at the end of counseling and after the two additional sessions. The findings show that Career Construction Counseling was effective, allowing a significant increase in vocational certainty, vocational identity, career decision-making, and a decrease in psychological distress. After counseling, participants in the add-on intervention fostering reconceptualization innovative moments revealed greater gains in vocational identity and psychological distress than those in the comparison group. The practical implications of these findings are discussed.  相似文献

The socio-demographic characteristics of couriers who work through digital platforms in Mexico reveal that more than 85 per cent of these workers have completed full-time secondary education and 83 per cent of these workers are young (aged 14 to 44). However, only 25 per cent are covered for health services and social security benefits. Against this backdrop, and guided by international experience, we set out a proposal to provide these workers with a tailored package of social security benefits. The proposal would require to categorize couriers who work through digital platforms as “digital workers”, introduce a special scheme for these workers based on voluntary affiliation, and offer a specific portfolio of benefits.  相似文献

The aim of this study was to examine the mediating effect of role ambiguity on the relationship between climate and job satisfaction in local public administration. Taking the job demands-resources model (JD-R) as the starting point, a multilevel mediation analysis was used to determine the influence of the different services within the sample. The sample consisted of 196 employees in 29 integrated services of two local corporations. Results confirm the job demands-resources model by showing multilevel partial mediation of role ambiguity in the relationship between climate and job satisfaction of public employees. These results indicate the importance of climate in organizational contexts and its implications for reducing role stressors while strengthening and maintaining the wellbeing of employees.  相似文献

Adverse childhood experiences (ACEs) are associated with an increased risk for school dropout. This study examined pathways from childhood adversity to school dropout through academic, behavioral, emotional, and social pathways. Data were collected prospectively from 728 adolescents and their caregivers who participated in the Longitudinal Studies of Child Abuse and Neglect and from child protective services records. Path analyses revealed a direct association between ACEs and dropout, as well as indirect effects through poor reading achievement and elevated externalizing problems. ACEs were associated with elevated internalizing problems, which were negatively associated with dropout. However, ACEs were not associated with peer influences. Implications of the identified mechanisms in the ACEs and school dropout association for future preventive interventions are discussed.  相似文献
