The Goldschmidt Hypothesis in Chile1

Abstract The claim that large farms with hired labor undermine community institutions and reduce average welfare while family farms enhance these dimensions is tested in the context of Chile's expanding large-scale export agriculture. The expected negative effect of scale shows up statistically but then disappears when an appropriate regional control is introduced. However, further analysis reveals a negative rural production effect that withstands this control and sets the stage for a competitive test. The counter hypothesis explored rejects production organization of any size as causal, proposing instead that two dimensions of provincial structure-urban differentiation and pluralism-interact with efficient production organization, seen as an ad hoc factor, to determine welfare levels. A partial test of this structural mediation model explains much of the variance of infant mortality (the criterion of welfare). Scale has no effect.     

Simplicity out of complexity in environmental modelling: Occam's razor revisited

While large models based on a deterministic-reductionist philosophy have an important part to play in environmental research, it is advantageous to consider alternative modelling methodologies which overtly acknowledge the poorly defined and uncertain nature of most environmental systems. The paper discusses this topic and presents an integrated statistical modelling procedure which involves three main methodological tools: uncertainty and sensitivity studies based on Monte Carlo simulation techniques; dominant mode analysis using a new method of combined linearization and model-order reduction; and data-based mechanistic modelling. This novel approach is illustrated by two practical examples: modelling the global carbon cycle in relation to possible climate change; and modelling a horticultural glasshouse for the purposes of automatic climate control system design.     

Economic evaluation of drug court: methodology, results, and policy implications

The purpose of this study was to conduct a cost-benefit analysis of three Drug Court programs in Kentucky for two groups of Drug Court participants: program graduates and program terminators. The economic benefits of the Drug Court programs were estimated relative to a comparison group of individuals who were assessed for the Drug Court programs, but did not enter the programs. This study highlights important factors in estimating the costs and the economic benefits of a Drug Court program. Results indicated that, particularly for graduates, Drug Court involvement was associated with reductions in incarceration, mental health services, and legal costs, as well as increases in earnings and child support payments. Net benefits and benefit–cost ratios for each program are presented and policy implications are discussed.     

The structural causes of infant mortality decline in Chile

The effect of macro processes on infant mortality rates is explored in this analysis of Chilean provincial statistics over five decades. Urbanization and pluralism, as measured by the percent of the population in urban centers and the percent voting, predict lower infant mortality strongly and consistently. The theoretical rationale for linking macrostructural variables to biological outcomes is then examined in more detail. It is argued that the structural model employed here is an improvement on the conventional modernization/biomedical explanation because of its greater consistency and specificity, and because inclusion of measures of health technology in the tests did not eliminate the effect of the structural variables.

Stepping‐Stone to Intergenerational Mobility? The Springboard,Safety Net,or Mobility Trap Functions of Korean Immigrant Entrepreneurship for the Second Generation1

Much research has viewed immigrant entrepreneurship positively because of its reputed role in immigrant economic adaptation. With the growing professionalization of children of Korean immigrant proprietors, small business ownership is seen as a stepping‐stone to intergenerational mobility. To assess whether immigrant entrepreneurship serves as springboard to upward mobility for the second generation, this article compares the educational and occupational achievements between children of entrepreneurs and children of professionals. The comparisons reveal that a higher proportion of children of professionals attended selective colleges, obtained professional occupations, and earned competitive salaries. Results from multiple regression analyses also indicate that entrepreneurship was not a good predictor of college selectivity and earnings for the second generation. Nevertheless, children of entrepreneurs attained comparable educational and occupational achievements as those of children of professionals, suggesting that rapid financial security through entrepreneurship can replicate similar residential and educational opportunities for children of entrepreneurs. While the springboard and safety net functions of small business on intergenerational mobility are salient, in some circumstances, obligations to help out in a family business can lead to personal sacrifice on the part of children of entrepreneurs, constraining their educational and occupational choices and leading some toward downward mobility.     

An evaluation of youth empowerment tobacco prevention programs in the Southwest

Evaluation research pertaining to the development of assessment instruments that fully capture the facets of empowerment prevention perspectives among youth are sparse. With funding from the American Legacy Foundation, the University of New Mexico Center for Health Promotion and Disease Prevention, in partnership with the New Mexico State Department of Health, developed a measure of individual empowerment. Drawing from the various bodies of literature in adolescent development, substance abuse prevention, and program/coalition building, a questionnaire was developed to capture facets of individual empowerment as it pertains to tobacco prevention efforts among youth within New Mexico. Utilizing a sample of 112 youth participants, principal axis factor analysis with Varimax rotation revealed four valid sub-scales entitled active participation, empowerment efficacy, external organizational involvement, and participant satisfaction. Internal consistency reliabilities were satisfactory with Cronbach's alpha ranging from .78 to .84. Regression mediation analysis revealed that active participation mediated the relationship of empowerment efficacy and self-esteem. Challenges associated with conceptualizing and assessing empowerment among youth are discussed.     

Maternity services and the discharge process: A review of practice in Queensland

BackgroundEfforts to increase postnatal support available to women and families are hampered by inadequate referral mechanisms. However, the discharge process in maternity services has received little research attention.AimTo review current discharge practices in Queensland, in order to identify mechanisms to minimise fragmentation in the care of women and families as they transition from hospital-based postnatal care to community-based health and other services.MethodsA survey of discharge practices in Queensland hospitals that offer birthing services (N = 55) and content analysis of discharge summary forms used by those hospitals.FindingsFifty-two Queensland birthing hospitals participated in the study. Discharge summaries were most commonly sent to General Practitioners (83%), less commonly to Child and Family Health Nurses (CFHNs; 52%) and rarely to other care providers. Discharge summaries were usually disseminated within one week of discharge (87%), but did not capture any information about care provided by domiciliary services. Almost one-fifth (19%) of hospitals did not seek women's consent for the disclosure of their discharge summary and only 10% of hospitals had processes for women to check accuracy. Significant gaps in the content of discharge summaries were identified, particularly in psychosocial and cultural information, and post-discharge advice. The format of discharge summaries diminished their readability.ConclusionDischarge summaries (format and content) should be consistent, comprehensive and specific to maternity services. Discharge summaries should be generated and disseminated electronically at the time of discharge from the maternity service. Women should review their discharge summaries and direct and consent to its dissemination.
