Creating Tactile Space during a University Extension Field Day Event: The Case of a Sustainable Agriculture Innovation

Drawing on the concept of “tactile space,” we evaluate the experiential learning environment of a university extension field day event focused on a sustainable agriculture innovation: biodegradable plastic mulch. Introduced by sociologist Michael Carolan, “tactile spaces” are sensuously rich learning environments where participants interact with each other and the environment in an “embodied” and “embedded” manner leading to long‐lasting attitudinal and behavioral change. In our study, farmers, extension professionals, crop consultants, and mulch manufacturers participated in a field day event designed to provide both embodied and embedded experiences in an effort to stimulate interest in biodegradable plastic mulch, an economically and environmentally sustainable alternative to polyethylene mulch. Field day participants engaged in hands‐on demonstrations preceded and followed by focus group sessions. Enhancing the learning environment in these ways improved the success of the field day event by encouraging practice‐based forms of learning, which supplemented and reinforced the claims made about biodegradable plastic mulch. However, the tactile space could have been enriched by providing more opportunities for participants to become embedded within the environment, and by adding elements to overcome the temporal limitations of the field day event. This research contributes to the broader literature on participatory research and extension.     

Broadening constructions of family violence: mothers' perspectives of aggression from their children

This qualitative study used feminist insights to explore experiential aspects of the phenomenon of child‐to‐mother violence from the perspectives of six women survivors. Participants took part in conversational style audiotaped interviews lasting between two and four hours. Feminist analysis revealed that fear and violence had become a feature of mothering for these women. Three themes were identified: It was only a matter of time: feeling intimidated and under threat; He just punched me: physical violence from child to mother; and Other men in the house: violence directed to the mothers by friends and associates of their children. Currently the literature overwhelmingly constructs family violence as elder abuse, spousal/partner violence, or child abuse, and generally fails to acknowledge, or address, violence from children to parents. However, findings from this study suggest that the discourse about family violence needs to be broadened to include child‐to‐mother violence. Implications of this study for practice and research are discussed.     

Drinking and Driving in Western Australia: Perceptions of Practices,Priorities and Preventives

If politics is the art of the possible, then determining what the public will tolerate is an important step in the design of prevention strategies. In this random survey of 1205 residents of country and urban areas in Western Australia, attitudes towards drinking and driving, drink-driving behaviour, and opinions of countermeasures were examined. Drink-driving was seen as an important issue for the community and there was a perception that something needed to be done. Drinking and driving was a well-established behaviour, but there was evidence that for many people ‘other’ people constitute the drink-driving problem. There were popular and unpopular preventives, but, interestingly, those that were deemed popular were often believed to be less effective than those that were less popular. The policy implications of these findings are considered, particularly in the light of the current implementation of random breath testing in Western Australia.     

Outcomes assessment of role-play scenarios for teaching responsible conduct of research

We describe the summative assessment of role-play scenarios that we previously developed to teach central topics in the responsible conduct of research (RCR) to graduate students in science and engineering. Interviews with role-play participants, with participants in a case discussion training session, and with untrained students suggested that role-playing might promote a deeper appreciation of RCR by shifting the focus away from wanting to simply "know the rules." We also present the results of a think-aloud case analysis study and describe the development of a behaviorally-anchored rating scale (BARS) to assess participants' case analysis performance.     

The Effects of the Registration System on the Seasonality of Births: The Case of the Soviet Union

Scientists study seasonality in order to understand the effect of environmental, biological, and social factors on demographic events. Poor data quality can also affect seasonal variation in mortality and fertility statistics. The influence of error on seasonal data becomes crucial as researchers analyze timing and spacing of events in time-series analyses. In this study we examine the reported number of births by month in the Soviet Union for 1950, 1955, and 1958–85. The lowest number of births has typically occurred in December, and the highest in January. This seasonal pattern is not consistent with any plausible biological or behavioural explanation. It is probably an artifact of attributing births that actually occurred during the preceding December or earlier, to January. This implies that Soviet statistical practice has not followed the stated policy of attributing births to the period (day, month, year) in which they occur. A substantial reduction between the 1950s and 1985 in the December-January peak in reported births implies marked improvement in Soviet vital registration statistics. The Soviet case shows that characteristics of the registration system can impart a particular seasonal pattern to demographic data. It also shows that officially prescribed procedures are not always followed in data generation, even in centrally planned economies. Researchers should carefully examine the quality of seasonal data before concluding that the data reflect real variations in demographic behaviour.     

Hypothesis Tests for Neyman's Bias in Case–Control Studies

Survival bias is a long recognized problem in case–control studies, and many varieties of bias can come under this umbrella term. We focus on one of them, termed Neyman's bias or ‘prevalence–incidence bias’. It occurs in case–control studies when exposure affects both disease and disease-induced mortality, and we give a formula for the observed, biased odds ratio under such conditions. We compare our result with previous investigations into this phenomenon and consider models under which this bias may or may not be important. Finally, we propose three hypothesis tests to identify when Neyman's bias may be present in case–control studies. We apply these tests to three data sets, one of stroke mortality, another of brain tumors, and the last of atrial fibrillation, and find some evidence of Neyman's bias in the former two cases, but not the last case.     

Ambiguity aversion in multi-armed bandit problems

In multi-armed bandit problems, information acquired from experimentation is valuable because it tells the agent whether to select a particular option again in the future. This article tests whether people undervalue this information because they are ambiguity averse, or have a distaste for uncertainty about the average quality of each alternative. It is shown that ambiguity averse agents have lower than optimal Gittins indexes, appearing to undervalue information from experimentation, but are willing to pay more than ambiguity neutral agents to learn the true mean of the payoff distribution, appearing to overvalue objectively given information. This prediction is tested with a laboratory experiment that elicits a Gittins index and a willingness to pay on six two-armed bandits. Consistent with the predictions of ambiguity aversion, the Gittins indexes are significantly lower than optimal and willingnesses to pay are significantly higher than optimal.

Exiting the Drug-Addict Role: Variations by Race and Gender

Our paper explores race and gender variations in the processes of exiting a “drug-addict role” and in creating a “recovering-addict role” within the ideological constraints of 12-Step programs. Our method is qualitative and features in-depth interviewing with 45 currently abstinent drug addicts from the 12-Step programs of Alcoholics Anonymous (A.A.) and Narcotics Anonymous (N.A.) in the Washington, D.C., Metropolitan Area as well as a residential and out-patient treatment program in mid-Michigan. Our respondents' exit processes typically began with doubts about the drug addict role followed by an often long and dynamic period of seeking alternatives to it without giving up drugs and alcohol completely. In some cases, however, participation in a new role initiated doubts about an existing one. Contrary to extant research, turning points or epiphanic moments in existing roles were not always identified. Most importantly, however, we found many differences by race and gender in what comprised the exit process. Gender socialization, cultural diversity, and the history of race relations in the United States help to explain this diversity.
