Sex offender notification and protective behavior

A primary purpose of sex offender community notification statutes is to give community members the opportunity to engage in precautionary behavior to prevent victimization. This exploratory study examines the effect of notification by comparing the behavior of 87 Hamilton County, Ohio, residents receiving sex offender notification to the behavior of 149 other residents who had not received notification. The findings indicate that notified respondents are significantly more likely to engage in behaviors to protect themselves and others from victimization, and to engage in community reporting behavior.     

An Elixir for Development? Olive Oil Policies and Poverty Alleviation in the Middle East and North Africa

The evolution of olive oil markets has sparked interest in policies that promote olive oil as a means of inducing rural development across the Middle East and North Africa. This article describes policies that link olive oil markets to rural development in Morocco, Syria and Tunisia and evaluate their effectiveness. It uses a framework that combines producer heterogeneity and market differentiation to describe how rural poverty impacts will be shaped by production, quality and marketing constraints. While the flow of olive oil from producers to the market may have increased, that of information and incentives in the reverse direction is still limited, something that too few olive oil policies aim to improve.     

A Perspective on Dioxin Emissions from Municipal Solid Waste Incinerators

This paper discusses the following key issues concerning human exposure to dioxins and furans emitted from typical, modern MSW incinerators: (1) Are MSW incinerators the major source of PCDD/PCDF input into the environment? (2) Are environmental concentrations around MSW incinerators substantially elevated relative to background levels? And (3) are MSW incinerators the major source of human exposure to PCDDs and PCDFs? Current scientific evidence indicates that (1) combustion sources in general (including steel mills, copper smelting plants, motor vehicles, pulp and paper mills, and MSW incinerators) are major sources of PCDD/PCDF input in the environment; (2) environmental concentrations of PCDDs and PCDFs around operating MSW incinerators are not substantially elevated; and (3) 99% of human exposure to PCDDs and PCDFs is from background contamination, even for individuals living near a modern MSW incinerator.     

Now What Do People Know About Global Climate Change? Survey Studies of Educated Laypeople

In 1992, a mental‐models‐based survey in Pittsburgh, Pennsylvania, revealed that educated laypeople often conflated global climate change and stratospheric ozone depletion, and appeared relatively unaware of the role of anthropogenic carbon dioxide emissions in global warming. This study compares those survey results with 2009 data from a sample of similarly well‐educated laypeople responding to the same survey instrument. Not surprisingly, following a decade of explosive attention to climate change in politics and in the mainstream media, survey respondents in 2009 showed higher awareness and comprehension of some climate change causes. Most notably, unlike those in 1992, 2009 respondents rarely mentioned ozone depletion as a cause of global warming. They were also far more likely to correctly volunteer energy use as a major cause of climate change; many in 2009 also cited natural processes and historical climatic cycles as key causes. When asked how to address the problem of climate change, while respondents in 1992 were unable to differentiate between general “good environmental practices” and actions specific to addressing climate change, respondents in 2009 have begun to appreciate the differences. Despite this, many individuals in 2009 still had incorrect beliefs about climate change, and still did not appear to fully appreciate key facts such as that global warming is primarily due to increased concentrations of carbon dioxide in the atmosphere, and the single most important source of this carbon dioxide is the combustion of fossil fuels.     

Evaluating Weight of Evidence in the Mystery of Balkan Endemic Nephropathy

Balkan endemic nephropathy (BEN) is a chronic, progressive wasting disease of the kidneys, endemic in certain rural regions of the Balkan nations Croatia, Serbia, Bulgaria, and Romania. It is irreversible and ultimately fatal. Though this disease was first described in the 1950s, its causes have been a mystery and a source of much academic and clinical contention. Possible etiologic agents that have been explored include exposure to metals and metalloids, viruses and bacteria, and the dietary toxins aristolochic acid (AA) and ochratoxin A (OTA). AA is a toxin produced by weeds of the genus Aristolochia, common in Balkan wheat fields. Aristolochia seeds may intermingle with harvested grains and thus inadvertently enter human diets. OTA is a mycotoxin (fungal toxin) common in many foods, including cereal grains. In this study, we analyzed the weight of evidence for each of the suspected causes of BEN using the Bradford Hill criteria (BHC): nine conditions that determine weight of evidence for a causal relationship between an agent and a disease. Each agent postulated to cause BEN was evaluated using the nine criteria, and for each criterion was given a rating based on the strength of the association between exposure to the substance and BEN. From the overall available scientific evidence for each of these suspected risk factors, AA is the agent with the greatest weight of evidence in causing BEN. We describe other methods for testing causality from epidemiological studies, which support this conclusion of AA causing BEN.     

Self Actualization in Marital Enrichment

The study attempted to evaluate the effectiveness of the Pairing Enrichment Program (PEP), a marriage enrichment program, in enhancing self-actualization. Shostrom's Personal Orientation Inventory (POI) was administered to an experimental group of married couples immediately prior to participating in PEP. A waiting list control group completed the POI at the same time. Three weeks later, following the completion of PEP for the experimental group, the POI was again administered to both groups. An analysis of co-variance was performed to test the effects of gender, group, and the interaction of these two factors on change in self-actualization (Post-POI minus Pre-POI), adjusting for six co-variables: Education of each, age of each, number of years married, and number of children. The results indicated that 1) being husband or wife had no significant effect on one's level of self-actualization, and that 2) the change in level of self-actualization was significantly greater (Positive Direction) for PEP participants than for non-PEP participants on the "I" and "C" scales of the POI     

Helping family members manage medication administration hassles

Managing the medication regimens of dependent older adults in the home is a complex issue for family caregivers. The tasks involved can include helping the older adults manage their own medications or may require involvement in the purchasing, scheduling, and administering of multiple medications for serious conditions. The hassles associated with this responsibility are now known to be associated with increased caregiver strain. In this article, we provide an overview of the body of research on medication administration hassles and offer a tool to assess family caregivers who are involved in this important aspect of care.     

Understanding Gaps Between the Risk Perceptions of Wildland–Urban Interface (WUI) Residents and Wildfire Professionals

Research across a variety of risk domains finds that the risk perceptions of professionals and the public differ. Such risk perception gaps occur if professionals and the public understand individual risk factors differently or if they aggregate risk factors into overall risk differently. The nature of such divergences, whether based on objective inaccuracies or on differing perspectives, is important to understand. However, evidence of risk perception gaps typically pertains to general, overall risk levels; evidence of and details about mismatches between the specific level of risk faced by individuals and their perceptions of that risk is less available. We examine these issues with a paired data set of professional and resident assessments of parcel‐level wildfire risk for private property in a wildland–urban interface community located in western Colorado, United States. We find evidence of a gap between the parcel‐level risk assessments of a wildfire professional and numerous measures of residents’ risk assessments. Overall risk ratings diverge for the majority of properties, as do judgments about many specific property attributes and about the relative contribution of these attributes to a property's overall level of risk. However, overall risk gaps are not well explained by many factors commonly found to relate to risk perceptions. Understanding the nature of these risk perception gaps can facilitate improved communication by wildfire professionals about how risks can be mitigated on private lands. These results also speak to the general nature of individual‐level risk perception.
