This study examines the differences between adolescents who do versus those who do not use contraceptives after the birth of their first child. The sample consists of 89 low-income mothers in the state of Indiana. A discriminant function analysis is used to determine if the adolescents' home environment, financial resources, self-esteem, or future orientation discriminates between contracepting and noncontracepting adolescents. If the adolescent is not receiving financial support from a romantic partner, intends to have another child within the next year, and expects to be a single parent in one year, she is less likely to be using contraceptives. 相似文献

Over the last few decades in the United States, the poverty rate for female-headed families has been about five times the poverty rate for other family types. This paper addresses the question of why, in general, female-headed families are so much poorer than other families. Recognizing that individuals choose their own marital status, a self-selection model is used to identify the factors which determine the poverty rates for married-couple families, families headed by females with no husband present, and families headed by males with no wife present. The following control variables are found to be important determinants of poverty for all three family types: education of family members; age, race, disability, and unemployment of the family head; geographical location, size and composition of the family. Both married-couple families and male-headed families are found to be less poor than female-headed families mainly because the marginal effects of the control variables, and to a lesser extent the mean levels of the control variables, favor the former two types of families over female-headed families. 相似文献

This paper examines inter-provincial female migration in Chile for the 1965--1970 period, with a view to describing socioeconomic characteristics of migrant women and to determining differences and similarities in age, educational level, occupation, and type of move (first, return, or repeat) between movers to the capital and to other urban areas. Data are from a five percent sample of the 1970 Chilean census. Findings reveal that non-return migrants to other urban areas are differentiated from those to Santiago by an older age structure, higher educational levels, higher status occupations, and are more likely to be making a second (or higher-order) move. Moreover, educational measures suggest that recent female migration to urban Chile is more prevalent among the upper than the lower strata of the society. 相似文献

This paper presents a developmental framework for assessing family function. It integrates family systems theory and ego psychological knowledge of growth. The framework organizes family information along four developmental lines, and a socio-biological stressor scale. Although this paper is only a beginning conceptualization and outline, it is hoped that with further study it can lead to family diagnosis and more definitive family treatment. 相似文献

Discussions of manpower planning take place in the context either of national plans or of company plans. From time to time the view has been expressed that the coverage and the time scale of these two types of planning are so different that there is nothing in common between them. This paper considers whether, in practice, ‘manpower’ is really so different from ‘personnel’. After all, the individuals regarding whom both plans are made are the same people; in both cases the planners are concerned with the posts they are to fill, with their salaries and with their mobility. 相似文献

This article examines the argument that gender mainstreaming offers the way forward for closing the gender pay gap. It juxtaposes research on the process of gender mainstreaming with our account of the processes involved in Australian state government Inquiries into the gender pay gap since the late 1990s. We indicate that the continuous process of analysis and response that gender mainstreaming can offer demands political will, intensive links between research and action, and adequate resources — which means that gender mainstreaming is seldom delivered in practice. We use our account of the Australian Inquiries to argue that, provided adequate political and financial resources are in place, the gender pay gap can be narrowed through the institutional mechanisms of an industrial relations system but that the regulatory approach is limited by its vulnerability to changes in industrial relations policy. The article concludes that, whatever strategy is used to narrow the gender pay gap, it must be able to show those who use and observe it that gender itself is a continuous, effortful and political process. 相似文献

Quantitative microbial risk assessment was used to predict the likelihood and spatial organization of Mycobacterium tuberculosis ( Mtb ) transmission in a commercial aircraft. Passenger exposure was predicted via a multizone Markov model in four scenarios: seated or moving infectious passengers and with or without filtration of recirculated cabin air. The traditional exponential ( k = 1) and a new exponential ( k = 0.0218) dose-response function were used to compute infection risk. Emission variability was included by Monte Carlo simulation. Infection risks were higher nearer and aft of the source; steady state airborne concentration levels were not attained. Expected incidence was low to moderate, with the central 95% ranging from 10−6 to 10−1 per 169 passengers in the four scenarios. Emission rates used were low compared to measurements from active TB patients in wards, thus a "superspreader" emitting 44 quanta/h could produce 6.2 cases or more under these scenarios. Use of respiratory protection by the infectious source and/or susceptible passengers reduced infection incidence up to one order of magnitude. 相似文献

Preferences for state opting out are thought of as being the expression of underpinning conflicts of states national identity, empirical evidence on its underlying behavioural processes is scarce. This paper draws upon evidence form the Basque Country to examine the support for a hypothetical opting out from the Spanish State in the light of a reformulation of [Ackerlof, G.A., Kranton, R.E., 2000. Economics and Identity. Quarterly Journal of Economics, 115, 715–753]. We use representative survey data from the Spanish Institute of Sociological Research for the Basque Country. To adjust our empirical specification to the prevalent hypothesis we employ a recursive seemingly unrelated probit approach. Our results suggest evidence for a simultaneous and endogenous influence of national identity on political preferences for the opting out of the Basque Country from Spain. We find evidence consistent with an instrumental conception of identity as motivating preferences for nation-state opting out, and status quo bias. 相似文献
