Abstract Dairy farmers in Michigan's Upper Peninsula, an economically marginal rural region, are encumbered by contextual constraints that are not similarly faced by their downstate counterparts. However, this does not mean that they are any less ambitious or less efficient in dealing with the resources available to them. Indeed, dairying and similar small-scale economic enterprises in this and other marginal contexts may be quite competitive and sustainable if appropriate sociopolitical supports are instituted and, in the case of dairying, if marketing orders and regulatory policies are formulated and implemented in light of their impact upon the economic growth and viability of the wider region. To explore this issue, we consider the situations, basic characteristics, and restructuring trends over time of dairy farms in three upstate localities as compared with that of a downstate dairy farming community.  相似文献

Research on the disincentives for quitting under employer-sponsored pension plans have limited generalizability as tests of the implicit contract thesis because of the way that job changing, pension back-loading, and plausible alternative explanations for pension effects have been operationalized. Using a unique data set that addresses some of these concerns, I find that pension back-loading and insecurity about the viability of a long-term employment contract are quantitatively the most significant determinants of job search intentions, followed by other seniority related benefits, such as vacation pay and shared investments in firm-specific training. No support for pension information, wage tilt, or efficiency wage arguments is found. Males and the better educated are also more likely to intend to search. Implications for theory, policy, and future research are discussed. I thank Morley Gunderson for helpful comments made on an earlier draft of this paper. Financial assistance from the Social Sciences and Humanities Research Council is gratefully acknowledged.  相似文献

First‐ and second‐born adolescent siblings from 21 families completed a daily diary on each of 7 days. The frequency and content of siblings' conversations are described and the relationship between the content of siblings' discussion and their perceived academic, athletic, and peer competency is explored. Siblings most often talked about extracurricular activities, media, and academics. The remaining topics, friends, family, eating, and body image, were the focus of discussion <10% of the time. The extent to which siblings discussed extracurricular activities, media, and academics was connected to perceived competency. Discussion focuses on the sibling relationship as an important context for adolescent development.  相似文献

Privatisation of the state-owned British railway system was completed in 1997. The following 6 years saw four serious fatal train accidents, leading to 49 deaths. These were the train collisions at Southall in 1997 and Ladbroke Grove in 1999, each caused by trains passing red signals, and the derailments at Hatfield in 2000 and Potters Bar in 2002, each caused by defective track. Has safety been compromised by the sell-off of the railways? Andrew Evans looks at the evidence and asks has privatisation led to more accidents?  相似文献

Regression modeling is used to predict gambling patterns in Australia on the basis of the unit record files underlying the Australian Bureau of Statistics’ Household Expenditure Survey of 6,892 households. The four largest categories of gambling expenditure are examined, namely: lottery tickets, lotto-type games and instant lottery (scratch cards), TAB (pari-mutuel wagering) and related on course betting, and poker (slot) machines and ticket machines. Determining factors analyzed include the source and level of household income, family composition and structure, welfare status, gender, age, ethnicity and geographic location. Apart from the determinants of expenditure varying widely across the different types of gambling activity, the results generally indicate that the source of household income is more important than the level of income and that household composition and regional location are likewise significant in determining gambling expenditure.   相似文献

Through examining the case of people with epilepsy (which, as we demonstrate, has an ambiguous status in relation to both popular and academic conceptions of disability) we explore the fluid, negotiable and contingent nature of identity and, in particular, the identification as ‘disabled’. Disability, we argue, cannot be reduced to either biology or social oppression, or even primarily to biological or social factors: it is the outcome of a complex interaction between a multiplicity of factors – biological, environmental, social, psychological, cultural and political – which will interact and be experienced differently by different people, at different times and in different situations. Rather than conceiving of disability in ‘all or nothing’ terms and of differing explanations as competing and mutually exclusive, it would be more productive to see them as partial and potentially complementary contributions to the better understanding of a complex and multifarious reality.  相似文献

U.S.‐born children of immigrants may be less likely to receive some social services than are children of native‐born parents if foreign‐born parents who are themselves ineligible are less likely to apply on their children's behalf. We use retrospective data from a sample of about 2,400 lowincome households in three U.S. cities to determine whether children with foreign‐born caregivers are less likely than children with native‐born caregivers to receive benefits from any of five programs over a two‐year period: TANF, SSI, Food Stamps, Medicaid, and WIC. The most significant disparities between children of citizen and noncitizen caregivers are in TANF and food stamp use.  相似文献
