Objective: This study is designed to evaluate heavy-truck drivers' following behavior and how a crash warning system influences their headway maintenance.Background: Rear-end crashes are one of the major crash types involving heavy trucks and are more likely than other crash types to result in fatalities. Previous studies have observed positive effects of in-vehicle crash warning systems in passenger car drivers. Although heavy-truck drivers are generally more experienced, driver-related errors are still the leading factors contributing to heavy-truck-related rear-end crashes.Method: Data from a 10-month naturalistic driving study were used. Participants were 18 professional heavy-truck drivers who received warnings during the last 8 months of the study (treatment period) but not during the first 2 months (baseline period). Time headway and driver's brake reaction time were extracted and compared with condition variables, including one between-subjects variable (driver shift) and five within-subjects variables (treatment condition, roadway types, traffic density, wiper state, and trailer configuration).Results: The presence of warnings resulted in a 0.28-s increase of mean time headway with dense on-road traffic and a 0.20-s increase with wipers on. Drivers also responded to the forward conflicts significantly faster (by 0.26 s, a 15% enhancement) in the treatment condition compared with responses in the baseline condition.Conclusion: Positive effects on heavy-truck drivers' following performance were observed with the warning system.Application: The installation of such in-vehicle crash warning systems can help heavy-truck drivers keep longer headway distances in challenging situations and respond quicker to potential traffic conflicts, therefore possibly increasing heavy-truck longitudinal driving safety.

The effects of vehicle package, seat, and anthropometric variables on posture were studied in a laboratory vehicle mockup. Participants (68 men and women) selected their preferred driving postures in 18 combinations of seat height, fore-aft steering wheel position, and seat cushion angle. Two seats differing in stiffness and seat back contour were used in testing. Driving postures were recorded using a sonic digitizer to measure the 3D locations of body landmarks. All test variables had significant independent effects on driving posture. Drivers were found to adapt to changes in the vehicle geometry primarily by changes in limb posture, whereas torso posture remained relatively constant. Stature accounts for most of the anthropometrically related variability in driving posture, and gender differences appear to be explained by body size variation. Large intersubject differences in torso posture, which are fairly stable across different seat and package conditions, are not closely related to standard anthropometric measures. The findings can be used to predict the effects of changes in vehicle and seat design on driving postures for populations with a wide range of anthropometric characteristics. [ABSTRACT FROM AUTHOR]

The objectives of this study were to 1) collect and analyze recent pedestrian crash cases for better understanding of the pedestrian injury distribution and mechanism, 2) use computational simulations to reconstruct pedestrian cases and estimate potential benefit of pedestrian automatic emergency braking (PedAEB) in reducing pedestrian injury risks, and 3) estimate how future pedestrian crash distribution might influence priorities for pedestrian protection. Analyses of national crash-injury dataset showed that the overall number of pedestrians in crashes as well as the serious and fatal pedestrian injuries in the U.S. have been increasing in recent years. Striking vehicle type has changed (i.e., decreased proportion of passenger cars and increase of SUVs and pickup trucks) from 20 years ago mirroring changes in the fleet distribution of vehicle sales. A total of 432 pedestrian injury cases were generated by linking the Michigan trauma data and police-reported crash data from 2013 to 2018. Among the linked cases, pickup trucks and SUVs were involved in crashes with more injuries across body regions. Notably, AIS 3+ chest injuries occur at almost the same rate as lower extremity injuries. A method, combining MADYMO simulations (n = 3,500), response surface model, and data mining, was developed to reconstruct 25 linked pedestrian crash cases to estimate the effectiveness of PedAEB. Based on national field data and MADYMO simulations, PedAEB was estimated to be effective in reducing the risk of head and lower extremity injuries but is relatively less effective in reducing the risk of chest injuries. The increased proportions of SUVs and pickup trucks in the vehicle fleet and the higher penetration of PedAEB may highlight the importance of future research into chest injury risk for pedestrian protection., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Objective: Barriers to healthcare professional (HP) (HP)-led sexual support in cancer care include lack of knowledge, skills and evidence-based educational interventions, to equip HPs to address sexual challenges faced by patients and partners. Consequently, sexual support is often avoided. This study examined HPs' acceptability and usability of the Maximising Sexual Wellbeing: Cancer Care (MSW|CC) eLearning resource for HPs and evaluated its impact on HPs' sexual attitudes and beliefs to providing sexual support in cancer care., Methods: HPs (n = 87) completed pre and post-test surveys using the modified 12-item Sexual Attitudes and Beliefs Scale (SABS). Post-test, participants rated acceptability and usability of the MSW|CC, with optional free-text comments. A repeated measures t-test assessed changes in HPs' scores on the SABS. Descriptive statistics and reporting of free text comments were used to explore HPs' perspectives of the MSW|CC., Results: SABS scores increased significantly from Time 1 (M = 35.1, SD = 4.8) to Time 2 (M = 40.1, SD = 4.3), t (86) = -10.2, p < 0.001 (two-tailed) with a medium effect size (d = 0.55); indicating a decrease in HPs' attitudinal barriers to providing sexual support. The MSW|CC was deemed acceptable, user-friendly and easy to navigate. Healthcare professionals would recommend the use of this eLearning resource to others (3.78/4, SD = 0.5), considered it a good informational resource (3.78/4, SD = 0.5) and straightforward to use (3.8/4, SD 0.42)., Discussion/conclusion: The MSW|CC reduced HPs' attitudinal barriers towards the provision of HP-led sexual support in cancer care, whilst being acceptable and useable. The MSW|CC could support implementation of global clinical guidelines advocating for HP-led sexual support across the treatment trajectory., (© 2022 John Wiley & Sons Ltd.)

Objectives: To adapt the theory-driven and positively evaluated Maximising Sexual Wellbeing| Prostate Cancer (MSW|PC) eLearning resource to an eLearning resource suitable for health professionals (HPs) working with mixed cancer populations, followed by usability and acceptability testing., Methods: Guided by Person-Based Approach (PBA) and Biopsychosocial Model, the MSW|PC was adapted by combining evidence from the literature, an expert group (n = 27: patients, partners, and HPs working in cancer care) and the research team. New content was developed relevant for a mixed cancer population. The Maximising Sexual Wellbeing| Cancer Care (MSW|CC) eLearning prototype was usability tested and modified with HPs using "think aloud" interviews (n = 18)., Results: Many identified sexual challenges were common across cancer populations, with additional information required for breast, colorectal, gynaecological, head and neck, and prostate cancers. During the testing phase, navigational difficulties were identified and resolved. HPs reported the MSW|CC as engaging, informative, and relevant with helpful communication and signposting tools to support practice., Conclusion: This systematic and iterative PBA yielded important insights to enhance the content and usability of MSW|CC. This novel resource provides HPs working across cancer care with tools to potentially address the gap in knowledge and skills and positively impact future sexual healthcare provision across cancer care., (© 2022.

Understanding driver behavior is the basis for the development of many advanced driver assistance systems, and experimental studies are indispensable tools for constructing appropriate driver models. However, the high cost associated with testing is a serious obstacle in collecting large amounts of experimental data. This paper presents a methodology that can improve the reliability of results from experimental studies with a limited number of participants by creating a virtual population. Specifically, a methodology based on Bayesian inference has been developed, that generates synthetic cases that adhere to various real-world constraints and represent possible variations of the observed experimental data. The application of the framework is illustrated using data collected during a test-track experiment where truck drivers performed a right turn maneuver, with and without a cyclist crossing the intersection. The results show that, based on the speed profiles of the dataset and physical constraints, the methodology can produce synthetic speed profiles during braking that mimic the original curves but extend to other realistic braking patterns that were not directly observed. The models obtained from the proposed methodology have applications for the design of active safety systems and automated driving, demonstrating thereby that the developed framework has great promise for the automotive industry., (Copyright © 2021 The Authors.

Community rapid response may reduce opioid overdose harms, but is hindered by the lack of timely data. To address this need, we created and evaluated the Michigan system for opioid overdose surveillance (SOS). SOS integrates suspected fatal overdose data from Medical Examiners (MEs), and suspected non-fatal overdoses (proxied by naloxone administration) from the Michigan Emergency Medical Services (EMS) into a web-based dashboard that was developed with stakeholder feedback. Authorised stakeholders can view approximate incident locations and automated spatiotemporal data summaries, while the general public can view county-level summaries. Following Centers for Disease Control and Prevention (CDC) surveillance system evaluation guidelines, we assessed simplicity, flexibility, data quality, acceptability, sensitivity, positive value positive (PVP), representativeness, timeliness and stability of SOS. Data are usually integrated into SOS 1-day postincident, and the interface is updated weekly for debugging and new feature addition, suggesting high timeliness, stability and flexibility. Regarding representativeness, SOS data cover 100% of EMS-based naloxone adminstrations in Michigan, and receives suspected fatal overdoses from MEs covering 79.1% of Michigan's population, but misses those receiving naloxone from non-EMS. PVP of the suspected fatal overdose indicator is nearly 80% across MEs. Because SOS uses pre-existing data, added burden on MEs/EMS is minimal, leading to high acceptability; there are over 300 authorised SOS stakeholders (~6 new registrations/week) as of this writing, suggesting high user acceptability. Using a collaborative, cross-sector approach we created a timely opioid overdose surveillance system that is flexible, acceptable, and is reasonably accurate and complete. Lessons learnt can aid other jurisdictions in creating analogous systems., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021. No commercial re-use.

Sexual issues and treatment side effects are not routinely discussed with men receiving treatment for prostate cancer, and support to address these concerns is not consistent across settings. This study evaluates a brief e-learning resource designed to improve sexual wellbeing support and examine its effects on healthcare professionals' sexual attitudes and beliefs. Healthcare professionals ( n = 44) completed an online questionnaire at baseline which included a modified 12-item sexual attitudes and beliefs survey (SABS). Follow-up questionnaires were completed immediately after the e-learning and at 4 weeks. Data were analysed using one-way, repeat measures ANOVAs to assess change in attitudes and beliefs over time. Significant improvements were observed at follow-up for a number of survey statements including 'knowledge and understanding', 'confidence in discussing sexual wellbeing' and the extent to which participants felt 'equipped with the language to initiate conversations'. The resource was seen as concise, relevant to practice and as providing useful information on potential side effects of treatment. In brief, e-learning has potential to address barriers to sexual wellbeing communication and promote delivery of support for prostate cancer survivors. Practical methods and resources should be included with these interventions to support implementation of learning and long-term changes in clinical behaviour.

Background: Sexual dysfunction is a frequent side effect associated with different prostate cancer treatment approaches. It can have a substantial impact on men and their partners and is associated with increased psychological morbidity. Despite this, sexual concerns are often not adequately addressed in routine practice. Evidence-based web-based interventions have the potential to provide ongoing information and sexual well-being support throughout all stages of care., Objective: The aim of this study is to examine the efficacy of a web-based self-management intervention designed to maximize sexual well-being in men living with prostate cancer and explore user perspectives on usability and acceptability., Methods: We used a single-arm study design, and participants were provided with access to the 5-step intervention for a period of 3 months. The intervention content was tailored based on responses to brief screening questions on treatment type, relationship status, and sexual orientation. Efficacy was assessed by using two-tailed, paired sample t tests for comparing the mean differences between pre- and postintervention measurements for exploring the participants' self-reported knowledge and understanding, sexual satisfaction, and comfort in discussing sexual issues. Usability and acceptability were determined based on the program use data and a postintervention survey for exploring perceived usefulness., Results: A total of 109 participants were recruited for this study. Significant postintervention improvements at follow-up were observed in the total scores (out of 20) from the survey (mean 12.23/20 points, SD 2.46 vs mean 13.62/20, SD 2.31; t 88 =9.570; P=.001) as well as in individual item scores on the extent to which the participants agreed that they had sufficient information to manage the impact that prostate cancer had on their sex life (mean 2.31/4 points, SD 0.86 vs mean 2.57/4, SD 0.85; t 88 =3.660; P=.001) and had the potential to have a satisfying sex life following treatment (mean 2.38/4 points, SD 0.79 vs mean 3.17/4, SD 0.78; t 88 =7.643; P=.001). The median number of intervention sessions was 3 (range 1-11), and intervention sessions had a median duration of 22 minutes (range 8-77). Acceptable usability scores were reported, with the highest result observed for the question on the extent to which the intervention provided relevant information., Conclusions: This study provides evidence on the efficacy of a tailored web-based intervention for maximizing sexual well-being in men living with prostate cancer. The results indicate that the intervention may improve one's self-perceived knowledge and understanding of how to manage sexual issues and increase self-efficacy or the belief that a satisfactory sex life could be achieved following treatment. The findings will be used to refine the intervention content before testing as part of a larger longitudinal study for examining its effectiveness., (©Sean R O'Connor, Carrie Flannagan, Kader Parahoo, Mary Steele, Samantha Thompson, Suneil Jain, Michael Kirby, Nuala Brady, Roma Maguire, John Connaghan, Eilis M McCaughan.

Purpose: eHealth and mHealth approaches are increasingly used to support cancer survivors. This review aimed to examine adherence, acceptability and satisfaction with Internet-based self-management programmes for post-surgical cancer rehabilitation and to identify common components of such interventions., Methods: Nine electronic databases were searched from inception up to February 15, 2020, for relevant quantitative and qualitative studies evaluating Internet-based cancer rehabilitation interventions. Studies were required to include an exercise or physical activity-based self-management intervention and a measure of adherence, acceptability or user satisfaction with the programme. Two independent reviewers performed all data extraction and quality assessment procedures. Data were synthesized using a narrative approach., Results: Six hundred ninety-six potential papers were identified and screened. Eleven met the inclusion criteria. Interventions had wide variations in levels of adherence, but the majority were reported as being acceptable to the users. Increased acceptability and user satisfaction were associated with interventions which were seen as time and cost-efficient, requiring acquisition of minimal or no new skills, which used coherent language, or which provided tailored information. The majority contained behaviour change components such as goal setting., Conclusions: Despite high levels of heterogeneity between studies, Internet-based approaches may be an acceptable method for the delivery of self-management interventions in post-surgical cancer rehabilitation., Implications for Cancer Survivors: There is a need for further studies exploring factors associated with increased user engagement and usage of digital interventions in cancer rehabilitation settings. These findings should be used to help develop interventions prior to testing their effectiveness in adequately powered randomized controlled trials.

Background: Long-term side-effects associated with different prostate cancer treatment approaches are common. Sexual challenges are the most frequently occurring issues and can result in increased psychological morbidity. It is recognized that barriers to communication can make initiating discussions around sexual concerns in routine practice difficult. Health care professionals need to routinely initiate conversations, effectively engage with patients, and assess needs in order to provide essential support. One proposed method that could support health care professionals to do this involves the use of prompts or structured frameworks to guide conversations., Objective: This study aimed to assess feasibility, acceptability, and satisfaction with the tablet-based Engagement, Assessment, Support, and Sign-posting (EASSi) tool designed to facilitate and structure sexual well-being discussions in routine prostate cancer care., Methods: Health care professionals (n=8) used the EASSi tool during 89 posttreatment appointments. Quantitative data were recorded based on program usage and surveys completed by health care professionals and patients. Qualitative data exploring perceptions on use of the tool were gathered using semistructured interviews with all health care professionals (n=8) and a sample of patients (n=10)., Results: Surveys were completed by health care professionals immediately following each appointment (n=89, 100%). Postal surveys were returned by 59 patients (66%). Health care professionals and patients reported that the tool helped facilitate discussions (81/89, 91% and 50/59, 85%, respectively) and that information provided was relevant (82/89, 92% and 50/59, 85%, respectively). The mean conversation duration was 6.01 minutes (SD 2.91). Qualitative synthesis identified the tool's ability to initiate and structure discussions, improve the "depth" of conversations, and normalize sexual concerns., Conclusions: The EASSi tool was appropriate and acceptable for use in practice and provided a flexible approach to facilitate routine brief conversations and deliver essential sexual well-being support. Further work will be conducted to evaluate the effectiveness of using the tablet-based tool in prostate cancer care settings., (©Eilís McCaughan, Carrie Flannagan, Kader Parahoo, John Connaghan, Roma Maguire, Mary Steele, Samantha Thompson, Suneil Jain, Michael Kirby, Nuala Brady, Seán R O'Connor.

This study is an extension of an experiment where the reliability of children's environment was manipulated before children completed the Marshmallow Task (Cognition, 2013, Vol. 126, pp. 109-114). In that experiment, Kidd, Palmeri, and Aslin found a significant difference in waiting time between two conditions in which the experimenter demonstrated reliability (by returning with promised reward) or unreliability (by not returning with rewardP). Children who had an unreliable experimenter did not wait as long during the Marshmallow Task, suggesting that delay gratification performance may be, in part, based on a rational decision. Due to the important theoretical and practical implications of this finding, we repeated the procedure of this experiment with 60 3- to 5-year-old children (twice as many as in the original study), but in a more familiar context (e.g., children's school instead of a lab). Using Bayesian analyses, we found an effect (albeit smaller than in the original study) of experimenter reliability as well as a significant gender by condition interaction effect., (Copyright © 2020 Elsevier Inc.

Objective: To systematically develop a framework to improve sexual wellbeing communication in routine prostate cancer care., Methods: The Theoretical Domains Framework was used to guide a multi-phase process used to identify components of the framework based on evidence reviews, semi-structured interviews and stakeholder workshops. 'Think-aloud' testing was used to explore usability, potential barriers and other factors relevant to implementation., Results: A conceptual communication framework consisting of 'Engagement' (E), 'Assessment' (A), information and 'Support' (S) and 'Sign-posting' (Si) sections was developed. The framework emphasises routine engagement to normalise sexual concerns, brief, non-sensitive assessment, personalised advice based on treatment type and relationship status, and a mechanism for referral to additional support or self-management resources in the form of a patient and partner handout. Usability testing identified strategies to promote implementation., Conclusions: The proposed framework is appropriate for use in routine practice and appears to be acceptable to patients, partners and healthcare professionals. Its use may help address gaps in sexual wellbeing support for men and partners living with prostate cancer. Further work will be conducted evaluating an online engagement tool, modelled on the framework., Practice Implications: The EASSi framework can facilitate and structure sexual wellbeing conversations and ensure fundamental but individualised support is provided routinely in prostate cancer care., Competing Interests: Declaration of Competing Interest The authors declare they have no competing interests., (Copyright © 2020 Elsevier B.V.

Objectives: Men who have sex with men (MSM) are at greater risk for human papillomavirus (HPV)-associated cancers. Since 2016, MSM have been offered the HPV vaccination, which is most effective when received prior to sexual debut, at genitourinary medicine clinics in the UK. In September 2019, the national HPV vaccination programme will be extended to boys. This study aimed to understand young MSM's (YMSM) knowledge and attitudes towards HPV vaccination., Design: Questionnaires assessed YMSM demographics, sexual behaviour, culture, knowledge and attitudes towards HPV vaccination and stage of vaccine decision-making using the precaution adoption process model. Focus groups explored sexual health information sources, attitudes, barriers and facilitators to vaccination and strategies to support vaccination uptake. Questionnaire data were analysed using descriptive statistics and focus group data were analysed thematically., Setting: Questionnaires were completed online or on paper. Focus groups were conducted within Lesbian Gay Bisexual Transgender Queer organisational settings and a university student's union in England and Northern Ireland., Participants: Seventeen YMSM (M=20.5 years) participated in four focus groups and 51 (M=21.1 years) completed questionnaires., Results: Over half of YMSM were aware of HPV (54.9%), yet few (21.6%) had previously discussed vaccination with a healthcare professional (HCP). Thematic analyses found YMSM were willing to receive the HPV vaccine. Vaccination programmes requiring YMSM to request the vaccine, particularly prior to sexual orientation disclosure to family and friends, were viewed as unfeasible. Educational campaigns explaining vaccine benefits were indicated as a way to encourage uptake., Conclusions: This study suggests that to effectively implement HPV vaccination for YMSM, this population requires clearer information and greater discussion with their HCP. In support of the decision made by the Joint Committee on Vaccination and Immunisation, universal vaccination is the most feasible and equitable option. However, the absence of a catch-up programme will leave a significant number of YMSM at risk of HPV infection., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2018.

Objectives: To explore healthcare professional perceived barriers and facilitators to discussing sexual health and wellbeing with patients after diagnosis of chronic illness., Methods: Five databases were searched and included data were synthesised using a meta-ethnographic approach. Confidence in findings was assessed using the GRADE-CERQual framework. Searches, extraction and quality assessment procedures were conducted independently by at least two authors., Results: Concepts extracted from 30 included studies were used to develop a conceptual framework based on five overarching themes. These were [1] individual and societal attitudes to sex and sexual wellbeing [2], patient specific factors [3], organizational and professional factors [4], strategies to overcome barriers in practice and [5] perceived training needs. Healthcare professionals acknowledged the importance of discussing and providing support for sexual wellbeing needs, but recognized it is not routinely provided., Conclusions: While patient specific factors and organizational issues such as lack of time were frequently identified as barriers, intra-personal and social perceptions appear to have the strongest influence on healthcare professional perspectives., Practice Implications: Brief education and tools to support healthcare professionals to have effective conversations with patients are required. These should address social barriers, normalise sexual issues, and support healthcare professionals to initiate discussions around sexual concerns., (Copyright © 2018. Published by Elsevier B.V.)

Men who have sex with men (MSM) may be at higher risk for human papillomavirus (HPV)-associated cancers. Healthcare professionals' recommendations can affect HPV vaccination uptake. Since 2016, MSM up to 45 years have been offered HPV vaccination at genitourinary medicine (GUM) clinics in a pilot programme, and primary care was recommended as a setting for opportunistic vaccination. Vaccination prior to potential exposure to the virus (i.e., sexual debut) is likely to be most efficacious, therefore a focus on young MSM (YMSM) is important. This study aimed to explore and compare the knowledge and attitudes of UK General Practitioners (GPs) and sexual healthcare professionals (SHCPs) regarding HPV vaccination for YMSM (age 16-24). A cross-sectional study using an online questionnaire examined 38 GPs and 49 SHCPs, including 59 (67.82%) females with a mean age of 40.71 years. Twenty-two participants (20 SHCPs, p < 0.001) had vaccinated a YMSM patient against HPV. GPs lack of time (25/38, 65.79%) and SHCP staff availability (27/49, 55.10%) were the main reported factors preventing YMSM HPV vaccination. GPs were less likely than SHCPs to believe there was sufficient evidence for vaccinating YMSM (OR = 0.02, 95% CI = 0.01, 0.47); less likely to have skills to identify YMSM who may benefit from vaccination (OR = 0.03, 95% CI = 0.01, 0.15); and less confident recommending YMSM vaccination (OR = 0.01, 95% CI = 0.00, 0.01). GPs appear to have different knowledge, attitudes, and skills regarding YMSM HPV vaccination when compared to SHCPs., Competing Interests: The authors declare no conflict of interest. The funding sponsors had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript, and in the decision to publish the results.

This paper investigated the characteristics of vehicle longitudinal jerk (change rate of acceleration with respect to time) by using vehicle sensor data from an existing naturalistic driving study. The main objective was to examine whether vehicle jerk contains useful information that could be potentially used to identify aggressive drivers. Initial investigation showed that there are unique characteristics of vehicle jerk in drivers' gas and brake pedal operations. Thus two jerk-based metrics were examined: (1) driver's frequency of using large positive jerk when pressing the gas pedal, and (2) driver's frequency of using large negative jerk when pressing the brake pedal. To validate the performance of the two metrics, drivers were firstly divided into an aggressive group and a normal group using three classification methods (1) traveling at excessive speed (speeding), (2) following too closely to a front vehicle (tailgating), and (3) their association with crashes or near-crashes in the dataset. The results show that those aggressive drivers defined using any of the three methods above were associated with significantly higher values of the two jerk-based metrics. Between the two metrics the frequency of using large negative jerk seems to have better performance in identifying aggressive drivers. A sensitivity analysis shows the findings were largely consistent with varying parameters in the analysis. The potential applications of this work include developing quantitative surrogate safety measures to identify aggressive drivers and aggressive driving, which could be potentially used to, for example, provide real-time or post-ride performance feedback to the drivers, or warn the surrounding drivers or vehicles using the connected vehicle technologies., (Copyright © 2017 Elsevier Ltd.

Yellow signal indications at intersections are well-known to be a contributor to traffic crashes. This study examined drivers' behavior during yellow signal indication (i.e., indecision zone) maneuvers. Data from a driving simulator study was used, which included drivers' performance data when they encountered a yellow signal indication at intersections under different secondary-task conditions. This study calculated drivers' likelihood to go through a yellow signal indication and examined factors that are related to drivers' decision making on intersection traversing. The results showed that drivers' decision on stopping or not at a yellow signal indication was associated with different variables including age, distraction, pedal conditions, and time to stop line. Distracted drivers' insensitive behavior was also captured from the significant interaction effect between time to stop line and distraction conditions, which implied that intersection related crash risk may increase when drivers were distracted., (Copyright © 2015 Elsevier Ltd.

The Australian continent exhibits complex biogeographic patterns but studies of the impacts of Pleistocene climatic oscillation on the mesic environments of the Southern Hemisphere are limited. The koala (Phascolarctos cinereus), one of Australia's most iconic species, was historically widely distributed throughout much of eastern Australia but currently represents a complex conservation challenge. To better understand the challenges to koala genetic health, we assessed the phylogeographic history of the koala. Variation in the maternally inherited mitochondrial DNA (mtDNA) Control Region (CR) was examined in 662 koalas sampled throughout their distribution. In addition, koala CR haplotypes accessioned to Genbank were evaluated and consolidated. A total of 53 unique CR haplotypes have been isolated from koalas to date (including 15 haplotypes novel to this study). The relationships among koala CR haplotypes were indicative of a single Evolutionary Significant Unit and do not support the recognition of subspecies, but were separated into four weakly differentiated lineages which correspond to three geographic clusters: a central lineage, a southern lineage and two northern lineages co-occurring north of Brisbane. The three geographic clusters were separated by known Pleistocene biogeographic barriers: the Brisbane River Valley and Clarence River Valley, although there was evidence of mixing amongst clusters. While there is evidence for historical connectivity, current koala populations exhibit greater structure, suggesting habitat fragmentation may have restricted female-mediated gene flow. Since mtDNA data informs conservation planning, we provide a summary of existing CR haplotypes, standardise nomenclature and make recommendations for future studies to harmonise existing datasets. This holistic approach is critical to ensuring management is effective and small scale local population studies can be integrated into a wider species context., Competing Interests: EH is employed by Ecoplan Australia Pty Ltd.

The objective of this study was to determine the level of knowledge about wheelchair transportation safety practices among wheelchair users (WCUs) and caregivers, therapists, physicians, and other professionals (CTPs). Two 10-question surveys were designed. One was administered to a convenience sample of 107 WCUs, average age 31 years (range: 4 to 86). Diagnoses included cerebral palsy (39%), spinal cord injury (19%), and others. The second was given to a convenience sample of 87 caregivers (33%), therapists (27%), physicians (18%), and others. Results indicated that most WCUs (67%) and about half of the CTPs had not received education about best transportation practices. Less than 20% in either group had heard of the transit option or a transit wheelchair, and less than 7% were aware of SAE J2249 and ANSI-RESNA WC/19 standards for wheelchairs and transportation. Sixty-seven percent of WCUs and 46% of CTPs felt lack of knowledge restricted their use of best transportation practices, followed by cost and vehicle space. Education about best practices was related to increased knowledge as well as increased use of occupant and wheelchair restraints. We concluded that there is a poor level of knowledge about wheelchair transportation safety practices among WCUs, caregivers, and professionals who prescribe wheelchairs. This knowledge deficit leads to a lack of standardized transport and a potential compromise of safety. Education can be beneficial, and should be pursued.
