The Feedback Effect: Does Exposure to Interviewer Feedback Affect an Observer\u27s Perception of Veracity and Guilt?

Historically, assessing deception has been rooted in the belief that a guilty suspect displays signs of anxiety. Based on a suspect’s physical demeanor and other behavioral cues presented during an interrogative session, law enforcement personnel (LEP) will utilize a set of techniques to elicit information about a crime. One such technique is the administration of feedback, which is the verbal assessment of a suspect’s guilt. The issue that stems from administering feedback lies not only in how it is given but also how it is received and interpreted by others. In a two-part study, the possibility of a “Feedback Effect” was examined. It is the idea that observers will infer deception and overall guilt of a suspect by taking their cues either directly from an interrogator’s feedback (direct pathway) or indirectly from a suspect’s feedback-elicited anxiety (indirect pathway). Participant observers were asked to rate the veracity and ultimate guilt of a suspect. Some of the observers were exposed to feedback (direct pathway) and others were not (indirect pathway). Results from the current study supported the direct pathway of the Feedback Effect, but not the indirect pathway: Observers who were exposed to feedback were more likely to see the suspect as deceptive; those not exposed to the feedback did not. Implications for jury decision-making are discussed

Social Marketing–Enhanced Home Energy Education Encourages Adoption of Energy-Saving Practices

We developed a program centered on a social marketing–enhanced home energy education visit to encourage homeowner adoption of specific energy conservation measures. We randomly assigned 170 homeowners to an experimental condition that included energy education before an energy audit or a control condition that included only an energy audit. Participants in the experimental condition adopted more no-cost and low-cost one-time energy conservation changes, such as adjusting refrigerator/freezer temperatures and lowering hot water temperature. However, they did not invest more in home energy renovations or other costly changes, such as replacing inefficient appliances. We discuss implications of this experiment for enhancing effectiveness of Extension-based energy education programs

Optimum Saving and Growth: Harrod on Dynamic Welfare Economics

In the 1960s and 1970s Harrod shifted the emphasis of his research in economic dynamics from the study of business cycles (instability principle) to the investigation of the growth process. As part of that, he restated his concept of the natural growth rate as an optimum welfare rate. The present paper examines Harrod's dynamic welfare economics, built around his concept of optimum saving developed as a reaction to Ramsey's approach to capital accumulation. It is shown that, according to Harrod, the saving rate does not affect the long-run growth rate of per capita income, which is determined by technical progress. Moreover, the economy will grow at the natural (full employment) rate only if economic policy is able to bring saving to its "optimum" level in macroeconomic equilibrium. Harrod's interest in optimal growth was motivated by his double concern with growth policy in mature economies and economic development in poor countries

Evaluation and costs of volunteer telephone cessation follow-up counseling for Veteran smokers discharged from inpatient units: a quasi-experimental, mixed methods study

Abstract Background The Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework was used to evaluate the volunteer telephone smoking cessation counseling follow-up program implemented as part of the inpatient Tobacco Tactics intervention in a Veterans Affairs (VA) hospital. Methods This was a quasi-experimental, mixed methods design that collected data through electronic medical records (EMR), observations of telephone smoking cessation counseling calls, interviews with staff and Veterans involved in the program, and intervention costs. Results Reach: Of the 131 Veterans referred to the smoking cessation telephone follow-up program, 19% were reached 0–1 times, while 81% were reached 2–4 times. Effectiveness: Seven-day point-prevalence 60-day quit rates (abstracted from the EMR) for those who were reached 2–4 times were 26%, compared to 8% among those who were reached 0–1 times (p = 0.06). Sixty-day 24-hour point-prevalence quit rates were 33% for those reached 2–4 times, compared to 4% of those reached 0–1 times (p < 0.01). Adoption and Implementation: The volunteers correctly followed protocol and were enthusiastic about performing the calls. Veterans who were interviewed reported positive comments about the calls. The cost to the hospital was $21 per participating Veteran, and the cost per quit was$92. Maintenance: There was short-term maintenance (about 1 year), but the program was not sustainable long term. Conclusions Quit rates were higher among those Veterans that had greater participation in the calls. Joint Commission standards for inpatient smoking with follow-up calls are voluntary, but should these standards become mandatory, there may be more motivation for VA administration to institute a hospital-based, volunteer telephone smoking cessation follow-up program.

Trophic ecology of piscivorous Arctic charr (Salvelinus alpinus (L.)) in subarctic lakes with contrasting food-web structures

The trophic ecology of piscivorous Arctic charr (Salvelinus alpinus (L.); charr) in the food webs of large subarctic lakes is not well understood. We assessed charr diets, parasites, growth, maturity, and stable isotope ratios in Fennoscandian subarctic lakes dominated by monomorphic or polymorphic whitefish (Coregonus lavaretus (L.)) populations. Charr density was low in all lakes, except in profundal habitats. Charr shifted to piscivory at small size (16-25 cm total length) and consumed a range of prey-fish sizes (2-25 cm). Cannibalism was observed in a few individuals from one monomorphic whitefish lake. Charr matured at 37-51 cm (5-8 years old), grew to 52-74 cm maximum observed length and 47-83 cm asymptotic length. Charr increased total area of convex hull and core stable isotopic diversity area of the fish community by 51-98% and 44-51% in monomorphic whitefish lakes, but only 8-11% and 7-10% in polymorphic whitefish lakes. The difference was due to increasing food-chain length in monomorphic whitefish lakes, whereas reliance on littoral carbon did not change. Charr were the top piscivores in monomorphic whitefish lakes, but played a less important role in polymorphic whitefish lakes, which contained a more diverse predator fauna.Peer reviewe

Uncomfortable yet Necessary: The Impact of PPE on Communication in Emergency Medicine

Background: The efficacy of pre-hospital emergency services is heavily dependent on the effective communication of care providers. This effective communication occurs between providers as part of a team, but also among providers interacting with family members and patients. The COVID-19 pandemic introduced a number of communication challenges to emergency care, which are primarily linked to the increased use of PPE. Methods: We sought to analyze the impacts of the Covid-19 pandemic on Emergency Medical Service (EMS) workers and pre-hospital care delivery. We conducted focus groups and one-on-one interviews with fire-EMS first responders between Sept 2021 and 2022. Interviews included questions about job related stress, EMS skills, work experiences and changes during Covid-19. Interviews were recorded, independently dual coded, and analyzed for themes. Results: 223 first responders participated in 40 focus groups and 40 lead paramedics participated in individual interviews. We found that additional use of personal protective-equipment (PPE) was reported to have significantly impaired efficiency and perceptions of quality of care—among EMS team members and also between EMS workers and patients. EMS personnel also experienced on scene hostility on arrival (from both families and other agencies). Use of extensive PPE muffles voices, obscures facial expressions, and can cause team members to have difficulty recognizing and communicating with one another and can be a barrier to showing empathy and connecting with patients. Creative solutions such as putting a hand on someone’s shoulder, wearing name tags on suits, and explaining rationale for perceived delays were mentioned as methods to transcend these barriers. The appearance of providers in heavy PPE can be unsettling and create barriers to human connection, particularly for pediatric patients. Conclusion: Human connection is an important element of health care delivery and healing. These findings shed light on new skills that are needed to initiate and maintain human connection in these times of PPE use, especially full body PPE. Awareness of the communication and empathy barriers posed by PPE is the first step to improving provider-patient interactions in pre-hospital EMS. Additionally, ‘communication-friendly’ adaptations of PPE equipment may be an important area for future research and development in manufacturing and the healthcare industry

Barriers to help-seeking among music festival attendees in New South Wales, Australia

Introduction: Prompt help-seeking behaviour by music festival attendees can reduce risks associated with drug use; however, little is known about perceived barriers to help-seeking when experiencing or witnessing illness at music festivals. We explored potential barriers and their association with festivalgoer characteristics. Methods: We conducted an on-site cross-sectional survey of attendees at New South Wales music festivals in 2019/2020. Perceived barriers to help-seeking in the hypothetical event of the respondent or a friend becoming unwell at the festival were assessed, and regression analyses were conducted to identify characteristics associated with these barriers. Results: Across six festivals, 1229 people were surveyed and four-fifths (83.2%) reported ≥1 barrier: 32.7% fear of getting in trouble with the police, 20.6% not knowing where to find help, 17.2% not knowing how unwell someone might be and 15.3% concern about friends or relatives finding out. In multivariable analyses, people of diverse sexuality and people using drugs that day had greater odds of reporting fear of trouble with the police. People reporting drug use that day had lower odds of reporting not knowing where to find help. Men, gender-diverse people and people using drugs that day had greater odds of reporting concern about friends or relatives finding out. Discussion and Conclusions: Our data substantiate concerns regarding policing strategies and their impact on festivals. Initiatives to support conversations about drugs with friends and families may be best targeted to younger people and those from gender-diverse backgrounds
