Science and Political Imperatives: Orders of Precedence

An ideal view is sketched of the relationship between the facts established in science and the values of ethics and politics, and of the distinction between them. Some necessary qualifications are drawn, which do not essentially undermine the ideal. Then two cases of scientific work are considered in which considerations of value may in different ways be playing a more intimate role in the science than the ideal would suggest. These are Darwin’s theory of evolution and the current consensus on climate change. Are any general lessons to be drawn from these cases?     

Print Me an Organ? Ethical and Regulatory Issues Emerging from 3D Bioprinting in Medicine

Recent developments of three-dimensional printing of biomaterials (3D bioprinting) in medicine have been portrayed as demonstrating the potential to transform some medical treatments, including providing new responses to organ damage or organ failure. However, beyond the hype and before 3D bioprinted organs are ready to be transplanted into humans, several important ethical concerns and regulatory questions need to be addressed. This article starts by raising general ethical concerns associated with the use of bioprinting in medicine, then it focuses on more particular ethical issues related to experimental testing on humans, and the lack of current international regulatory directives to guide these experiments. Accordingly, this article (1) considers whether there is a limit as to what should be bioprinted in medicine; (2) examines key risks of significant harm associated with testing 3D bioprinting for humans; (3) investigates the clinical trial paradigm used to test 3D bioprinting; (4) analyses ethical questions of irreversibility, loss of treatment opportunity and replicability; (5) explores the current lack of a specific framework for the regulation and testing of 3D bioprinting treatments.     

On the relation between theory of mind and executive functioning: A developmental cognitive neuroscience perspective

Theory of mind (ToM) and executive functioning (EF) show marked interrelatedness across childhood, and developmental psychologists have long been interested in understanding the nature of this association. The present review addresses this issue from a cognitive neuroscience perspective by exploring three hypotheses regarding their functional overlap: (1) ToM relies on EF (EF→ToM); (2) EF relies on ToM (ToM→EF); and (3) ToM and EF are mutually related, owing to shared neural structures or networks (ToM?EF). Drawing on evidence from normative brain development, neurodevelopmental and neurodegenerative diseases, patient lesion studies, and brain-imaging studies, we suggest that only a strict version of the ToM?EF proposal of complete neural overlap can be confidently ruled out on the basis of existing evidence. The balance of evidence suggests that separable neurobiological mechanisms likely underlie ToM and EF, with shared mechanisms for domain-general processing that support both abilities. We highlight how future studies may empirically substantiate the nature of the ToM–EF relationship using various biobehavioral approaches.     

Virtual Reality and Cognitive-Behavioral Therapy for Driving Anxiety and Aggression in Veterans: A Pilot Study

Within the U.S. military, motor vehicle accidents (MVAs) are the leading cause of preventable morbidity and mortality. Prior combat exposure and anxiety symptoms are associated with risky and aggressive driving, which is responsible for over half of MVA fatalities. Therefore, interventions are needed to reduce driving anxiety and aggression in veterans in order to mitigate the public health impact of MVAs. Virtual reality exposure therapy (VRET) offers safe, controlled exposure to distressing stimuli. The current study piloted a novel virtual reality and cognitive behavioral intervention (VRET + CBT) for veterans that integrated both anxiety and anger management components. Virtual reality driving scenarios were delivered in a driving simulator and tailored for the military population. Six previously deployed veterans completed eight intervention sessions, as well as pre/post, one month follow-up and six to nine month follow-up assessments. Repeated measures ANOVAs demonstrated significant decline and large effect sizes for PTSD symptoms, driving phobia, hyperarousal in driving situations, anxiety/anger-related thoughts and behaviors, and risky driving. Hyperarousal in driving situations declined by 69%, aggressive driving declined by 29%, and risky driving declined by 21%. Treatment gains were maintained at follow-up. Recruitment, retention, immersion, simulator sickness scores, and qualitative feedback demonstrated feasibility of the intervention. Implications for future research and adaptation are discussed.     

Lost in the great divide: Motivation in religious studies classrooms

One of the most illuminating finds in Barbara E. Walvoord's Teaching and Learning in College Introductory Religion Courses (2008) is what she calls “the great divide,” a mismatch between instructors’ goals for their courses, which are academic, and the students’ reasons for taking them, which relate to their personal interests and development. Motivation – or, rather, the lack thereof – is not explicitly considered as a potential victim of this mismatch. This article will turn its attention squarely to this issue. First, I will review data about the “great divide” and link them to the common practice of asking our students to bracket the personal when they take our courses. The article will juxtapose this practice with what research tell us about motivation, which will allow us to further explore why the divide Walvoord and others have identified is so problematic. The article will conclude with pedagogical strategies that can help instructors intentionally influence motivation in religion courses. Ultimately, I suggest that we may be doing students – as well as ourselves, as the purveyors of our discipline – a disservice, if we do not attend to (or, worse, if we actively avoid) what we know motivates students to learn.     

Examining Psychosocial Pathways Underlying Gratitude Interventions: A Randomized Controlled Trial

Despite their unprecedented popularity, the psychological mechanisms through which gratitude journals operate are poorly understood. Also the use of gratitude journaling to enhance social relationships has been neglected in past research, despite the importance of healthy relationships for people’s happiness. This randomized controlled study examined the effect of (a) a traditional gratitude journal (fostering gratitude for daily life), and (b) an interpersonal gratitude journal (fostering gratitude for one’s existing social relationships), versus (c) an active control journal, on life satisfaction. Ninety-one participants were randomized to one of three conditions with 2-week and 1-month follow-ups. The traditional gratitude intervention (vs. control) showed improvements in friendship at immediate post-test and 1-month follow-up, and these effects were accounted for by changes in gratitude over time. Additionally, the traditional gratitude intervention (vs. control) predicted enhanced life satisfaction at follow-up, and this was serially mediated by 6 week changes in gratitude and perceived friendship quality. No such differences over time were observed between the interpersonal gratitude intervention and either the control intervention or the traditional gratitude intervention. Actively appreciating things in daily life appears to be effective in enhancing the quality of people’s social relationships, and producing sustained improvements in subjective wellbeing.     

Job demands and psychological well-being: Moderating role of occupational self-efficacy and job social support among mid-career academics

The study investigated the moderating role of occupational self-efficacy and job social support on the relationship between job demands and psychological well-being among mid-career academics. Participants were 203 academics at three public Nigerian universities (female = 37.93%; mean years of service = 8.58 years, SD = 2.20). The academics completed measures of job demands, occupational self-efficacy, job social support, and psychological well-being. Moderated regression analysis of the data suggested only occupational self-efficacy to moderate the relationship between work demands and psychological well-being. Findings underpin the buffering effects of work self-efficacy in employee psychological well-being with high job demands.     

The Good Immigrant Worker: 2013 US Senate Bill 744, Color-Blind Nativism and the Struggle for Comprehensive Immigration Reform

We explore immigration politics in the contemporary USA through analysis of the political framing of 2013 US Senate Bill 744, especially among its supporters. SB 744 is a bipartisan comprehensive immigration reform proposal that called for the largest overhaul of the immigration system in more than 25 years; it was passed in June 2013 by the US Senate but blocked in the House. Through analysis of the 2012–2013 textual content of the official websites and blogs of six US immigration lobby organizations from across the political spectrum, we offer a typology of political framings of comprehensive immigration reform. Drawing on popular anti-immigrant rhetoric, organizations with an agenda of immigration restriction and deterrence battled against the bill. On the other side, supporters of the bill ranged from business coalitions to immigrant rights groups, an assortment of interests that was reflected in the variety of arguments advanced in favor of the bill. Despite the far more fragmented character of pro-SB 744 discourse in comparison to that advanced by the opposition, our investigation suggests the ongoing and contested formation of a strategic pro-SB 744 framing that centered on the “good immigrant worker,” a “race-blind” trope that melds US nationalist narratives of immigration with an ethos of neoliberalism that upholds individual merit and market value to create a notion of “deservingness” that affirms the worth of immigrants as diligent workers.
