A Night to Remember: A Harm-Reduction Birthday Card Intervention Reduces High-Risk Drinking During 21st Birthday Celebrations

Objective: In collaboration with Residence Life, the Heads UP research team developed a 21st birthday card program to help reduce the risky drinking often associated with these celebrations.

Participants: 81 students (28 males, 53 females) completed a post-21st birthday survey. Of these, 74 reported drinking during their 21st birthday and were included in the analyses.

Methods: During the 2005-2006 school year, the authors assigned students celebrating 21st birthdays to either receive an alcohol risk-reduction birthday card or to a no-card condition. The students completed a survey after their birthday.

Results: Students who received the card consumed fewer drinks and reached lower blood alcohol content (BAC) levels on their birthday than did students who did not receive it. Female students who received the card consumed 40% fewer drinks and reached nearly 50% lower BAC levels than women who did not receive it.

Conclusion: This program is easily replicated, inexpensive, and may be used by universities to reduce risk related to celebratory alcohol consumption.     

Review and Evaluation of the J100-10 Risk and Resilience Management Standard for Water and Wastewater Systems

Risk analysis standards are often employed to protect critical infrastructures, which are vital to a nation's security, economy, and safety of its citizens. We present an analysis framework for evaluating such standards and apply it to the J100-10 risk analysis standard for water and wastewater systems. In doing so, we identify gaps between practices recommended in the standard and the state of the art. While individual processes found within infrastructure risk analysis standards have been evaluated in the past, we present a foundational review and focus specifically on water systems. By highlighting both the conceptual shortcomings and practical limitations, we aim to prioritize the shortcomings needed to be addressed. Key findings from this study include (1) risk definitions fail to address notions of uncertainty, (2) the sole use of “worst reasonable case” assumptions can lead to mischaracterizations of risk, (3) analysis of risk and resilience at the threat-asset resolution ignores dependencies within the system, and (4) stakeholder values need to be assessed when balancing the tradeoffs between risk reduction and resilience enhancement.     

Religiosity as a Protective Factor against Heavy Episodic Drinking (HED) in Heterosexual,Bisexual, Gay,and Lesbian Young Adults

Although religiosity has been shown to be associated with positive outcomes in studies of general population samples, few studies have considered the potential differential effect of religiosity on those who are consolidating gay, lesbian, or bisexual (GLB) identities. Logistic regression analyses using a sample of 13,038 emerging adults from the National Longitudinal Survey of Adolescent Health (Add Health) revealed main effects for religiosity and a significant religiosity × sexual identity interaction in women. Specifically, religiosity was protective against alcohol use and heavy episodic drinking (HED) in heterosexual women, but not lesbian women. In bisexual women, higher religiosity increased the odds of alcohol use and HED. Among men, religiosity was protective, with no differential effects based on sexual identity. Prevention efforts should consider that individual religiosity may be a risk, rather than protective factor for some young adults.     

Significance of Exposure Assessment to Analysis of Cancer Risk from Inorganic Arsenic in Drinking Water in Taiwan

The primary source of evidence that inorganic arsenic in drinking water is associated with increased mortality from cancer at internal sites (bladder, liver, lung, and other organs) is a large ecologic study conducted in regions of Southwest Taiwan endemic to Blackfoot disease. The dose-response patterns for lung, liver, and bladder cancers display a nonlinear dose-response relationship with arsenic exposure. The data do not appear suitable, however, for the more refined task of dose-response assessment, particularly for inference of risk at the low arsenic concentrations found in some U.S. water supplies. The problem lies in variable arsenic concentrations between the wells within a village, largely due to a mix of shallow wells and deep artesian wells, and in having only one well test for 24 (40%) of the 60 villages. The current analysis identifies 14 villages where the exposure appears most questionable, based on criteria described in the text. The exposure values were then changed for seven of the villages, from the median well test being used as a default to some other point in the village's range of well tests that would contribute to smoothing the appearance of a dose-response curve. The remaining seven villages, six of which had only one well test, were deleted as outliers. The resultant dose-response patterns showed no evidence of excess risk below arsenic concentrations of 0.1 mg/l. Of course, that outcome is dependent on manipulation of the data, as described. Inclusion of the seven deleted villages would make estimates of risk much higher at low doses. In those seven villages, the cancer mortality rates are significantly high for their exposure levels, suggesting that their exposure values may be too low or that other etiological factors need to be taken into account.     

A Quantitative Risk Assessment of Waterborne Cryptosporidiosis in France Using Second-Order Monte Carlo Simulation

A pragmatic quantitative risk assessment (QRA) of the risks of waterborne Cryptosporidium parvum infection and cryptosporidiosis in immunocompetent and immunodeficient French populations is proposed. The model takes into account French specificities such as the French technique for oocyst enumeration performance and tap water consumption. The proportion of infective oocysts is based on literature review and expert knowledge. The probability of infection for a given number of ingested viable oocysts is modeled using the exponential dose-response model applied on published data from experimental infections in immunocompetent human volunteers challenged with the IOWA strain. Second-order Monte Carlo simulations are used to characterize the uncertainty and variability of the risk estimates. Daily risk of infection and illness for the immunocompetent and the immunodeficient populations are estimated according to the number of oocysts observed in a single storage reservoir water sample. As an example, the mean daily risk of infection in the immunocompetent population is estimated to be 1.08 x 10(-4) (95% confidence interval: [0.20 x 10(-4); 6.83 x 10(-4)]) when five oocysts are observed in a 100 L storage reservoir water sample. Annual risks of infection and disease are estimated from a set of oocyst enumeration results from distributed water samples, assuming a negative binomial distribution of day-to-day contamination variation. The model and various assumptions used in the model are fully explained and discussed. While caveats of this model are well recognized, this pragmatic QRA could represent a useful tool for the French Food Safety Agency (AFSSA) to define recommendations in case of water resource contamination by C. parvum whose infectivity is comparable to the IOWA strain.     

Mapping responsible conduct in the uncharted field of research-creation: A scoping review

This scoping review addresses the issues of responsible conduct of research (RCR) that can arise in the practice of research-creation (RC), an emergent, interdisciplinary, and heterogeneous field at the interface of academic research and creative activities. Little is yet known about the nature and scope of RCR issues in RC, so our study examined three questions: (1) What are the specific issues in RC in relation to RCR? (2) How does the specificity of RC influence the understanding and practice of RCR? (3) What recommendations could help address the issues highlighted in the literature? To answer these questions, we conducted a scoping review of the academic literature (n = 181 texts) dealing with RCR in RC. We found that researcher-creators faced some very different RCR challenges in comparison with their colleagues in the rest of academia. Addressing these issues is important for both the RCR and RC communities in order to ensure that the rapid development of this field occurs in line with the norms of RCR which, nonetheless, should be adapted to respect the particularities of RC and allow its contributions to the academic world.     

Using evidence-based research to redirect a conversation: Newspapers’ coverage of strategies to address college binge drinking

This study examines selected newspapers’ coverage of college binge drinking while also serving as an example of evidence-based practices that can be of use to public relations practitioners and health care professionals working to draw attention to important factors that are not being addressed in either public or policy conversations related to this issue. We examine newspaper coverage in 32 newspapers from 1997 to 2006 to determine which strategies to address college binge drinking are being covered and which of those are evidence-based and implemented by colleges. The mix of individual versus environmental strategies was examined based on Social Cognitive Theory. In the 255 articles analyzed, the majority of strategies covered were environmental. The most frequently covered strategy, increasing student knowledge, is individual and not evidence-based. Strategies classified as effective were not frequently covered. Media advocacy is offered as an evidence-based practice that public relations and health care professionals can use to affect change.     

Losses disguised as wins in multiline slots: using an educational animation to reduce erroneous win overestimates

Slot machines are available in several countries, with multiline games growing in popularity. Interestingly, many audiovisually reinforced small ‘wins’ in multiline games are in fact monetary losses – outcomes referred to as losses disguised as wins (LDWs). Research suggests that LDWs cause players to overestimate how many times they remember actually winning during a playing session. The study sought to replicate this finding and see if a short educational animation about LDWs could significantly reduce this LDW-triggered win overestimation effect. It employed a mixed design, with animation viewed (LDW, control) as the between-subjects factor, and game played (200 spins on a few LDW or many LDW game; game order counterbalanced) as the within-subjects factor. Fifty-four novice participants estimated how many times they won more than they wagered in each game. In the control animation group, the study replicated the LDW-triggered win overestimation effect for participants playing the many LDW game. Crucially, win overestimates were significantly reduced in this many LDW game for players exposed to the LDW animation. The study concludes that LDWs can lead novice gamblers to remember winning more often than they actually do during a playing session, but educating participants about LDWs can reduce these erroneous win overestimates.
