Does Privatization Protect Natural Resources? Property Rights and Forests in Guatemala

Objectives . Property rights are central to debates about natural resource policy. Governments traditionally have been seen as the appropriate custodians of natural resources for their citizens. More recently, many argue the privatization of property rights will ensure that users have incentives to manage their resources well. Common property, to the extent it is discussed at all, is seen as leading to the tragedy of the commons. We evaluate these claims by assessing property rights and forest conditions in two private and three communal forests in Guatemala. Methods . Data on biological and social phenomena from five forests (151 plots) and their associated communities were collected using the International Forestry Resources and Institutions Research Program protocols. Ordinary least squares regression was used to analyze four models. We examined t -scores for differences in coefficients for the different models. Results . The models demonstrate that de jure property rights are not a powerful predictor of variations among the sampled forests. Conclusions . We argue that de facto institutions and their enforcement are much more important than de jure property rights to forest management. Communities holding a forest in common can, under certain circumstances, create institutions to manage their resources as successfully as—or more successfully than—private owners.     

Reproductive and Developmental Risks from Ethylene Oxide: A Probabilistic Characterization of Possible Regulatory Thresholds

Ethylene oxide is a gas produced in large quantities in the United States that is used primarily as a chemical intermediate in the production of ethylene glycol, propylene glycol, non-ionic surfactants, ethanolamines, glycol ethers, and other chemicals. It has been well established that ethylene oxide can induce cancer, genetic, reproductive and developmental, and acute health effects in animals. The U.S. Environmental Protection Agency is currently developing both a cancer potency factor and a reference concentration (RfC) for ethylene oxide. This study used the rich database on the reproductive and developmental effects of ethylene oxide to develop a probabilistic characterization of possible regulatory thresholds for ethylene oxide. This analysis was based on the standard regulatory approach for noncancer risk assessment, but involved several innovative elements, such as: (1) the use of advanced statistical methods to account for correlations in developmental outcomes among littermates and allow for simultaneous control of covariates (such as litter size); (2) the application of a probabilistic approach for characterizing the uncertainty in extrapolating the animal results to humans; and (3) the use of a quantitative approach to account for the variation in heterogeneity among the human population. This article presents several classes of results, including: (1) probabilistic characterizations of ED10s for two quantal reproductive outcomes-resorption and fetal death, (2) probabilistic characterizations of one developmental outcome-the dose expected to yield a 5% reduction in fetal (or pup) weight, (3) estimates of the RfCs that would result from using these values in the standard regulatory approach for noncancer risk assessment, and (4) a probabilistic characterization of the level of ethylene oxide exposure that would be expected to yield a 1/1,000 increase in the risk of reproductive or developmental outcomes in exposed human populations.     

Mood and Audience Effects on Video Lottery Terminal Gambling

Little is known about the situational factors associated with gambling behavior. We induced 180 male participants (mean age: 21.6) into a positive, negative, or neutral mood prior to gambling on a video lottery terminal (VLT). While gambling, participants were observed by either a male peer, female peer, or no one. Induced mood had no effect on gambling behavior. Participants induced into a negative mood prior to gambling, however, reported more positive moods after gambling, whereas those with positive and neutral moods reported more negative moods after gambling. Participants observed by either a male or female peer spent less time gambling on the VLT compared to those not observed. Participants observed by a female peer lost less money relative to the other observer conditions. Degree of problem gambling in the last year had little influence on these effects. Some practical implications of these findings are discussed.     

Do single mothers in the United States use the Earned Income Tax Credit to reduce unsecured debt?

The Earned Income Tax Credit (EITC) is a refundable credit for low-income workers mainly targeted at families with children. This study uses the Survey of Income and Program Participation’s topical modules on Assets and Liabilities to examine associations between the EITC expansions during the early 1990s and the unsecured debt of the households of single mothers. We use two difference-in-differences comparisons over the study period 1988–1999, first comparing single mothers to single childless women, and then comparing single mothers with two or more children to single mothers with exactly one child. In both cases we find that the EITC expansions are associated with a relative decline in the unsecured debt of affected households of single mothers. While not direct evidence of a causal relationship, this is suggestive evidence that single mothers may have used part of their EITC to limit the growth of their unsecured debt during this period.     

t-Latinized Designs

A variety trial sometimes requires a resolvable block design in which the replicates are set out next to each other. The long blocks running through the replicates are then of interest. A t -latinized design is one in which groups of these t long blocks are binary. In this paper examples of such designs are given. It is shown that the algorithm described by John & Whitaker (1993) can be used to construct designs with high average efficiency factors. Upper bounds on these efficiency factors are also derived.     

Changing the Palace Guard: Analysing the Impact of Women's Entry into Medicine

Women's rapid entry into medicine raises important questions about change in this historically male-dominated profession. In addition to shifting the gender balance, do increasing numbers of women signal a more fundamental change in the way in which medicine is organized and practised? A growing body of research suggests such change. Yet there is continuing controversy about the meaning of observed gender differences in practice, whether they reflect an essentially pragmatic response to women's dual workload of family and career, or whether they are the result of underlying differences in attitudes, values and orientations. This article uses data from a survey of a recent cohort of family physicians in Ontario, Canada, to document the extent of gender differences and similarities in medical practice, and their interrelationships to family situation, political attitudes and patient care attitudes. The results show that seemingly related differences in practice are accounted for in different ways: while some are associated with differences in family situation, others are tied to attitudes, while others are a function of gender alone. The results also reveal gender similarities which do not suggest that women are becoming more like men, but that men, and the profession as a whole are changing. We would emphasize the importance of interpreting gender differences and similarities within a broader conceptual understanding of change in the profession.     

Public child welfare workers' perception of efficacy relative to multicultural awareness,knowledge and skills

Maintaining a well trained pool of workers in public child welfare agencies continues to be an ongoing problem. Research suggests that it is critical that we continue to explore the factors associated with worker efficacy. Existing research has found that outcomes for families and children are affected by numerous individual and organizational characteristics including worker's perceived efficacy (Advancement of Social Work Research, 2005; Bernotavicz, 2007; Collier, 2007; Ellett, 2007; Government Accountability Office, 2003; Milner, 2003). This study describes public child welfare workers, and their perceptions of efficacy relative to multicultural awareness, knowledge and skills. Study outcomes have implications for worker training, supervision, and curriculum on child welfare.     

Biological Pre‐emption: “Race”, Class,and Genomics

Genomics is a complex field of study involving researchers and practitioners immersed in the social milieu from which their genetic theories and comprehensions in part emerge. Genomic researchers' embeddedness in social formations with distinct ideologies predisposes them to construct hypotheses about genetics with value‐laden assumptions. Given genomics' inseparability from social influences this article explores how its use with marginalized groups has eugenic implications. Several important links between eugenics and genomics are identified suggesting eugenic implications in genomics.     

Managing the Care Home Closure Process: Care Managers' Experiences and Views

This paper reports case study research that set out to identifywhat care managers do during independent care home closures.Little research has focused on the way in which care homes forolder people are closed in England, or what those involved thinkabout the process. This paper reports the activities and viewsof care managers directly involved in helping older people relocatefrom care homes that were closed by their owners. During suchclosures, residents and their families have no choice but tomove, usually to a deadline, and with little control over theprocess. Care managers have a responsibility to help arrangealternative care for those current residents who are publiclyfunded, and to offer information and support to those fundingtheir own care (the ‘self-funded’). Closure relatedactivities could involve considerable staff time. Care managementarrangements, including the organization of teams and provisionof needs assessments, varied across authorities. The care managersdescribed drawing on emotional counselling and inter-personalskills, as well as practitioner knowledge and experience, particularlywhen offering support and advice about finding appropriate newhomes. Tensions between aims, constraints on their actions andviews of good practice are identified.
