A systematic review of observational studies investigating the influence of mobile phone distraction on road crossing behaviour of pedestrians

The growing prevalence of technological distractions amongst pedestrians makes it an important road safety concern. Observational studies are considered a reliable method to investigate the influence of mobile phone distraction on pedestrian road crossing behaviour and crash risks. The present study conducts a systematic review of international literature on pedestrian distraction observations by following the Preferred Reporting Items for Systematic Reviews and meta-Analyses (PRISMA) guidelines. A total of 792 studies were identified from the literature search on six research databases: Scopus, Google Scholar, Web of Science, PubMed, Cochrane library, and Transportation Research International Documentation (TRID). Finally, 39 research articles were assessed using the systematic classification scheme based on the following five research aspects: prevalence of mobile phone distraction, study locations, performance measures, analysis techniques, and additional factors associated with mobile phone use among pedestrians. Over 35% of the studies were conducted in the United States of America (USA) and 69% of the investigations were done in the last five years. Overall, the findings across the studies indicate that mobile phone distraction plays a major role in pedestrian risky road crossing behaviour and violation tendencies. Visual distractions (such as texting) exhibited higher behavioural impairment compared to cognitive distractions (e.g., listening to music, and conversations). Pedestrian characteristics such as gender and age were the key factors examined in 77% and 67% of the observational studies. Finally, important directions for future research are illustrated to aid the researchers working in the area of pedestrian safety.     

Developing Guidelines for Domestic Violence Offender Programs

Summary

This article reviews research on domestic violence that can help inform the development of guidelines for programs for men who batter. It also illustrates some successes and problems in other fields that might be instructive for the domestic violence field. Firm conclusions about “best practice” guidelines for intervention seem to be premature because of flaws in evaluation studies. In addition, there is growing evidence of variability among men who batter on dimensions such as severity of violence, childhood traumas, generality of violence and personality traits. Programs also need to be able to respond to motivational and cultural difference among abusers. Existence of variability implies the need for multiple forms of interventions.     

Competence

Summary

Competence in mental health is explored in many roles, including that of researcher, author, teacher, supervisor, therapist, evaluator, consultant, forensic specialist, case manager, and administrator. It is viewed not only as a construct but also as an ongoing process within the individual. Five fundamental areas are examined: (1) Maintaining high standards of competence, (2) keeping within one's boundaries of competence and limitations of one's expertise, (3) maintaining competence in human diversity in practice and research, (4) engaging in continuing education in scientific and professional areas, and (5) protecting the welfare of others when standards are lacking. Guidance is also received from ethics codes, published standards of practice, federal and state laws, and institutional policies and regulations.     

Compensating for failed attention while driving

While operating a motor vehicle, drivers must pay attention to other moving vehicles and the roadside environment in order to detect and process critical information related to the driving task. Using a driving simulator, this study investigated the effects of an unexpected event on driver performance in environments of more or less clutter and under situations of high attentional load. Attentional load was manipulated by varying the number of neighboring vehicles participants tracked for lane changes. After baseline-driving behavior was established, the unexpected event occurred: a pedestrian ran into the driver’s path. Tracking-accuracy, brake initiation, swerving, and verbal report of the unexpected pedestrian were used to assess driver performance. All participants verbally reported noticing the pedestrian. However, analyses of driving behavior revealed differences in the reactions to the pedestrian: drivers braked faster and had significantly less deviation in their steering heading with a lower attentional load, and participants in low clutter environments had a larger overall change in velocity. This research advances the understanding of how drivers allocate attention between various stimuli and the trade-offs between a driver’s focus on an assigned task and external objects within the roadway environment. Moreover, the results of this research lend insight into how to construct roadway environments that encourage driver attention toward the most immediate and relevant information to reduce both vehicle-to-vehicle and vehicle-to-pedestrian interactions.     

“We Need to Make Action NOW,to Help Keep the Language Alive”: Navigating Tensions of Engaging Indigenous Educational Values in University Education

Despite centuries of contact and conquest, Indigenous communities persist in maintaining their cultures and psychologies. Key to this success in cultural survival is the maintenance of Indigenous languages, which contain distinct worldviews. However, Indigenous languages are at risk, with fewer and fewer fluent Elder speakers. Fortunately, there remain committed groups of community educators who carry out Indigenous language education. Current mainstream teacher education programs do not typically introduce the importance of Indigenous language education to teacher candidates, who are the next generation of K‐12 teachers. We view this as highly problematic, and thus carried out a proof‐of‐concept project in which one U.S. university's American Indian/Alaska Native teacher candidates collaborated with, and learned from, Indigenous language educators during a two‐week‐long summer institute at the university. In our article, we share three main findings, based on qualitative analyses of daily‐written student journals collected during the two‐week pilot project: (a) Indigenous language education supports the social justice vision in the American Psychological Association's Multicultural Guidelines; (b) intergenerational educational opportunities are invaluable for affirming Indigenous psychologies; and (c) Indigenous community language educators do important survivance work. Our findings provide insight into how Indigenous language education is crucial for advancing education that honors Indigenous community psychological well‐being.     

Priority setting in health care: on the relation between reasonable choices on the micro-level and the macro-level

There has been much discussion about how to obtain legitimacy at macro-level priority setting in health care by use of fair procedures, but how should we consider priority setting by individual clinicians or health workers at the micro-level? Despite the fact that just health care totally hinges upon their decisions, surprisingly little attention seems being paid to the legitimacy of these decisions. This paper addresses the following question: what are the conditions that have to be met in order to ensure that individual claims on health care are well aligned with an overall concept of just health care? Drawing upon a distinction between individual and aggregated needs, I argue that even though we assume the legitimacy of macro-level guidelines, this legitimacy is not directly transferable to decisions at micro-level simply by adherence to the guidelines’ recommendation. Further, I argue that individual claims are subject to the formal principle of equality and the demands of vertical and horizontal equity in a way that gives context- and patient-related equity concerns precedence over equity concerns captured at the macro-level. I conclude that if we aim to achieve just health care, we need to develop a complementary framework for legitimising individual judgment of patients’ claims on health care resources. Moreover, I suggest the basic structure of such a framework.

人类干细胞研究的伦理学争论

关于干细胞研究的伦理学争论越来越成为热门话题。2000年8月23日,美国卫生研究所颁布了涉及人类多能胚胎干细胞研究的指南。指南允许联邦政府资助的研究者进行干细胞研究,但是按照布什总统2001年8月9日的决定,政府只资助有限制的干细胞研究。而在英国、法国、日本、澳洲、以及其他国家,干细胞研究不仅在私人的实验室里而且也在政府的实验室里进行着。无论如何,人类干细胞研究应该按照一定规范谨慎进行。     

Conflicts of interest: The implications of roadside advertising for driver attention

There is growing concern that roadside advertising presents a real risk to driving safety, with conservative estimates putting external distractors responsible for up to 10% of all road traffic accidents. In this report, we present a simulator study quantifying the effects of billboards on driver attention, mental workload and performance in Urban, Motorway and Rural environments. The results demonstrate that roadside advertising has clear adverse effects on lateral control and driver attention, in terms of mental workload. Whilst the methodological limitations of the study are acknowledged, the overriding conclusion is that prudence should be exercised when authorising or placing roadside advertising. The findings are discussed with respect to governmental policy and guidelines.     

Rumination, distraction, and mindful self-focus in depressed patients

Rumination has been proposed as a cognitive risk factor for the onset and maintenance of depression. In parallel, mindfulness interventions have shown to reduce the risk for recurrence of depressive episodes. This study aimed to investigate effects of short periods of induced rumination, distraction, and mindful self-focus on sad mood in depressed patients and to assess possible moderator effects of habitual variables on respective mood changes. Seventy-six depressed patients 3.5 years after discharge from inpatient treatment were subjected to negative mood induction and subsequently randomly assigned to a rumination, distraction, or mindful self-focus induction. Habitual aspects of rumination, distraction, and mindfulness were assessed by questionnaires. Compared to rumination, the induction of a mindful self-focus and of distraction showed clear beneficial effects on the course of negative mood. While habitual distraction predicted better mood outcomes across all conditions, patients high in habitual mindfulness tended to show stronger negative mood reduction specifically after the induction of a mindful self-focus. This study indicates that - similar to distraction - an experimentally induced mindful self-focus is able to reduce negative mood in depressed patients. Implications regarding possible subgroups of patients who might particularly benefit from mindfulness-based interventions are discussed.
