Psychological drivers of risk-reducing behaviors to limit human-wildlife conflict

Conflicts between people and wild animals are increasing globally, often with serious consequences for both. Local regulations or ordinances are frequently used to promote human behaviors that minimize these conflicts (risk-reducing behaviors), but compliance with ordinances can be highly variable. While efforts to increase compliance could be improved through applications of conservation psychology, little is known about the relative influence of different factors motivating compliance. Using concepts from psychology and risk theory, we conducted a longitudinal study pairing data from mail surveys with direct observations of compliance with a wildlife ordinance requiring residents to secure residential garbage from black bears (Ursus americanus). We assessed the relative influence of beliefs and attitudes toward bears and bear proofing, perceived behavioral control, perceived risks and benefits assigned to bears, norms, trust in management, previous experience with conflicts, and demographics on compliance behavior (i.e., bear proofing). Data on previous experience were obtained through direct observation and survey reports. We found that higher compliance rates were associated with more observed conflicts on a respondent's block. Counter to expectations, however, residents were less compliant when they were more trusting of the management agency and perceived more benefits from bears. We suggest that messages have the potential to increase compliance when they empower residents by linking successful management of conflicts to individual actions and emphasize how reducing conflicts could maintain benefits provided by wildlife. Modifying existing educational materials to account for these psychological considerations and evaluating their impact on compliance behavior over time are important next steps in changing human behaviors relevant to the globally important problem of human-wildlife conflict.

Public perspectives and media reporting of wolf reintroduction in Colorado

In the state of Colorado, a citizen ballot initiative to reintroduce gray wolves (Canis lupus) is eliciting polarization and conflict among multiple stakeholder and interest groups. Given this complex social landscape, we examined the social context surrounding wolf reintroduction in Colorado as of 2019. We used an online survey of 734 Coloradans representative in terms of age and gender, and we sampled from different regions across the state, to examine public beliefs and attitudes related to wolf reintroduction and various wolf management options. We also conducted a content analysis of media coverage on potential wolf reintroduction in 10 major daily Colorado newspapers from January 2019, when the signature-gathering effort for the wolf reintroduction initiative began, through the end of January 2020, when the initiative was officially added to the ballot. Our findings suggest a high degree of social tolerance or desire for wolf reintroduction in Colorado across geographies, stakeholder groups, and demographics. However, we also find that a portion of the public believes that wolves would negatively impact their livelihoods, primarily because of concerns over the safety of people and pets, loss of hunting opportunities, and potential wolf predation on livestock. These concerns-particularly those related to livestock losses-are strongly reflected in the media. We find that media coverage has focused only on a few of the many perceived positive and negative impacts of wolf reintroduction identified among the public. Our findings highlight the need to account for this diversity of perspectives in future decisions and to conduct public outreach regarding likely impacts of wolf reintroduction.

Cultural views of breastfeeding among high-school female students in Japan and the United States: a survey

This study compares the attitudes toward breastfeeding of high-school students in Japan and the United States. The study was conducted as a cross-sectional survey with a convenience sample (N = 329). Data were collected in 1989 and 1990 at two private, girls-only high schools (Tokyo, Japan and Farmington, Michigan). Retrieval rates were 100 percent (Tokyo) and 78 percent (Michigan) respectively. Responses were compared by the chi-square (chi 2) test with Yate's correction and factor analyses. Tokyo students perceived that their mothers talked positively about breastfeeding (54 percent), while only 17 percent of Michigan students reported that their mothers did so (< .001). Less than five percent of the Tokyo students felt that breastfeeding disturbs family life, whereas nearly 98 percent of the Michigan students felt so (p < .001). Tokyo students scored significantly higher on the 'family' factor, while the Michigan students scored significantly higher on the 'self' factor. Overall, this study indicates that high school students in Japan have more positive attitudes toward breastfeeding than students in the United States; however, teenagers in the United States are more interested than their Japanese age-mates in gaining information about breastfeeding.

Gel as a Definitive Property in GR-S Technology

1. Of the gel fraction that may occur in GR-S, only that portion which has low swelling volume in benzene—tight (B) gel—markedly affects processing behavior and quality of product. 2. As the proportion of tight (B) gel increases, mixing operations become more difficult, and the quality of the final vulcanizate is lowered; specifically, decreased tensile strength, increased modulus, and decreased cut-growth resistance result. Where maximum quality is desired, processing conditions which favor the formation of tight gel should be avoided. 3. Conversely, appreciable amounts of tight (B) gel aid the processing operations of calendering and extrusion by reducing shrinkage and roughness. Where ease of processing is paramount and quality defects can be tolerated, heat-plasticization cycles which favor gel formation may be used to advantage. 4. To account for the observed effects of tight gel, the theory is advanced that fillers cannot enter this gel portion. This explanation is supported by a limited amount of direct evidence. 5. Heat-plasticization studies of GR-S at 320° F in the presence and absence of carbon black indicate that the black reduces the tendency to gel formation. For short heat treatments, common to many factory processes, the effect has no significance. For extended heat plasticization, incorporation of the black first may be either advantageous or detrimental, depending on whether maximum quality or ease of processing is the end objective.
