The primary prevention of alcohol problems: a critical review of the research literature.

PubMed

Moskowitz, J M

1989-01-01

The research evaluating the effects of programs and policies in reducing the incidence of alcohol problems is critically reviewed. Four types of preventive interventions are examined including: (1) policies affecting the physical, economic and social availability of alcohol (e.g., minimum legal drinking age, price and advertising of alcohol), (2) formal social controls on alcohol-related behavior (e.g., drinking-driving laws), (3) primary prevention programs (e.g., school-based alcohol education), and (4) environmental safety measures (e.g., automobile airbags). The research generally supports the efficacy of three alcohol-specific policies: raising the minimum legal drinking age to 21, increasing alcohol taxes and increasing the enforcement of drinking-driving laws. Also, research suggests that various environmental safety measures reduce the incidence of alcohol-related trauma. In contrast, little evidence currently exists to support the efficacy of primary prevention programs. However, a systems perspective of prevention suggests that prevention programs may become more efficacious after widespread adoption of prevention policies that lead to shifts in social norms regarding use of beverage alcohol.

Strategies to reduce driving under the influence of alcohol.

PubMed

DeJong, W; Hingson, R

1998-01-01

The purpose of this review is to update research on the prevention of alcohol-related traffic deaths since the 1988 Surgeon General's Workshop on Drunk Driving. Four primary areas of research are reviewed here: (a) general deterrence policies, (b) alcohol control policies, (c) mass communications campaigns, including advertising restrictions, and (d) community traffic safety programs. Modern efforts to combat drunk driving in the United States began with specific deterrence strategies to punish convicted drunk drivers, and then evolved to include general deterrence strategies that were targeted to the population as a whole. Efforts next expanded to include the alcohol side of the problem, with measures installed to decrease underage drinking and excessive alcohol consumption. In the next several years, greater efforts are needed on all these fronts. Also needed, however, are programs that integrate drunk driving prevention with other traffic safety initiatives.

Preventing alcohol-related traffic injury: a health promotion approach.

PubMed

Howat, Peter; Sleet, David; Elder, Randy; Maycock, Bruce

2004-09-01

The conditions that give rise to drinking and driving are complex, with multiple and interrelated causes. Prevention efforts benefit from an approach that relies on the combination of multiple interventions. Health promotion provides a useful framework for conceptualizing and implementing actions to reduce drinking and driving since it involves a combination of educational, behavioral, environmental, and policy approaches. This review draws on data from a range of settings to characterize the effectiveness of various interventions embedded within the health promotion approach. Interventions considered part of the health promotion approach include: (1) economic interventions (2) organizational interventions, (3) policy interventions, and (4) health education interventions, including the use of media, school and community education, and public awareness programs. Effective health promotion strengthens the skills and capabilities of individuals to take action and the capacity of groups or communities to act collectively to exert control over the determinants of alcohol-impaired driving. There is strong evidence for the effectiveness of some components of health promotion, including economic and retailer interventions, alcohol taxation, reducing alcohol availability, legal and legislative strategies, and strategies addressing the servers of alcohol. There is also evidence for the effectiveness of sobriety checkpoints, lower BAC laws, minimum legal drinking age laws, and supportive media promotion programs. Other interventions with moderate evidence of effectiveness include restricting alcohol advertising and promotion, and actions involving counter advertising. Health education interventions alone that have insufficient evidence for effectiveness include passive server training programs, school drug and alcohol education programs, community mobilization efforts, and health warnings. Because each intervention builds on the strengths of every other one, ecological approaches to reducing alcohol-impaired driving using all four components of the health promotion model are likely to be the most effective. Settings such as schools, workplaces, cities, and communities offer practical opportunities to implement alcohol-impaired driving prevention programs within this framework.

Program Science is an iterative, multi-phase research and program framework where programs drive the scientific inquiry, and both program and science are aligned towards a collective goal of improving population health. To achieve this, Program Science involves the systematic application of theoretical and empirical knowledge to optimize the scale, quality and impact of public health programs. Program Science tools and approaches developed for strategic planning, program implementation, and program management and evaluation have been incorporated into HIV and sexually transmitted infection prevention programs in Kenya, Nigeria, India, and the United States. In this paper, we highlight key scientific contributions that emerged from the growing application of Program Science in the field of HIV and STI prevention, and conclude by proposing future directions for Program Science.

Vanlaar, Ward G M; Mainegra Hing, Marisela; Robertson, Robyn D

2017-03-01

Alcohol ignition interlock programs for offenders aim to reduce recidivism among convicted drink drivers. This study presents an evaluation of Nova Scotia's interlock program implemented in 2008 in order to assess its effectiveness to reduce impaired driving and to help identify areas for improvement. Data used include conviction and crash records of individual participants; provincial monthly counts of alcohol-related charges, convictions and fatal and serious crashes; and interlock logged events. Methods used include descriptive statistics, survival analysis, time series and logistic regression analysis. With respect to specific deterrence (i.e., preventing recidivism) there was a 90% reduction in recidivism among voluntary participants since participation in the interlock program and a 79% reduction after these participants exited from the program. With respect to general deterrence (i.e., referring to a preventative effect on the entire population of drivers in Nova Scotia) there were temporary decreases in the numbers of alcohol-related charges (13.32%) and convictions (9.93%) and a small significant decrease in the number of fatal and serious injury alcohol-related crashes, following the implementation of the program. The evidence suggests the interlock program was better at preventing harm due to alcohol-impaired driving than the alternative of not using the interlock program. Recommendations were formulated supporting the continuation of the interlock program in Nova Scotia. Copyright © 2017 Elsevier Ltd. All rights reserved.

Alcohol consumption among university students has reached worrying levels, its effects on driving being highly dangerous. This aspect emphasizes the need to develop prevention programs, intended to raise subjects' awareness about the effects of alcohol on driving. The aim of the present research is to evaluate the effectiveness of the intervention program «Tú decides», implemented at the Algarve University during several students festivals, between 2010-2014. Quasi-experimental study, pre-post test without control group. A total of 5,079 participants were inquired. They were asked, at two different moments, before and after the measurement of the blood alcohol level and giving an information session with technical recommendations to prevent driving under alcohol effects. One factor ANOVA test used, in order to perform a mean comparison, as well as the Chi-square statistics, to perform a proportion comparison (p<.05). It was found that the intention to drive was lower at the second moment (42.1%) (χ(2)=2078.71; p=.000). This intention was influenced by blood alcohol level different levels (χ(2)=338.252; p=.000), gender (χ(2)=35.718; p=.000), age (χ(2)=62.805; p=.000) and professional situation of the participants (χ(2)=27.397; p=.001). We can affirm that the main objective of this intervention was achieved, since the participants followed the technical recommendations based on the blood alcohol level results.

The drink driving situation in China.

Li, Ying; Xie, Donghua; Nie, Guangmeng; Zhang, Junhua

2012-01-01

China has been concerned about the serious problem of drinking and driving road crashes, and it has made good progress by establishing strict laws, imposing serious penalties, and initiating a rigorous enforcement program since 2008. This study has assessed the magnitude and nature of the problem and reviewed the legislation, current practices, and institutional capacities for preventing drinking and driving. Data and information were collected using existing reports and by consulting officials and experts from a number of agencies. Although there were no national statistics on levels of drinking and driving, random breath test surveys in 2 southern cities showed that between 4.5 and 4.6 percent of drivers were driving over the minimum legal blood alcohol concentration (BAC) limit of 20 mg/100 mL. Preliminary results from crash data also showed that at least 20 percent of serious road crashes were alcohol related in these cities. The national published figure for fatal crashes caused by drinking and driving was much lower, only 4 percent, but alcohol was not often identified as the main cause because of measurement difficulties. China's legislation sets 2 BAC limits that are comparable with international norms. It has recently increased the penalties for drunk driving, the more serious of the 2 offenses, with a minimum driving ban of 5 years. The police are actively enforcing the laws through frequent roadside checking but they need more resources. Alcohol breath tests before and after a combined publicity and enforcement campaign indicated reductions of 87 and 68 percent of drivers over the legal limit in 2 southern cities. China has made progress in strengthening its approach to preventing drinking and driving, particularly in the area of law enforcement. However, it is not possible to evaluate the potential benefits because of data issues. Recommendations for the future include the need to improve the national road crash and injury database, strengthen the coordination of key agencies, and provide more effective and sustained public information campaigns that target vulnerable drivers and are integrated with enforcement strategies. Evaluation and research are important to improve future prevention programs. Copyright © 2012 Taylor & Francis Group, LLC

Literature is lacking about the overall attitudes and utilization of texting. Understand attitudes and behaviors surrounding texting. A survey to evaluate attitudes and behaviors concerning texting was developed in conjunction with a social scientist. The survey (2009) was administered to university freshmen via an anonymous, web based program. The study was approved by the IRB. 426 university freshmen completed the survey. 67% reported texting was more useful than speaking by phone. 53% report they text more than 50 times per day. 24% report they text more than 100 times per day. 73% report they text while driving, though only 9% responded they do so frequently. 92% believe texting affects their concentration while driving. 84% reported they are passengers when the driver texts and 75% report they do not feel safe in the car when the driver is texting. 77% disagreed with the statement "It is no big deal to text while driving." 53% reported they can not safely text and drive and 60% agreed texting while driving should be illegal. 92% reported texting was less safe then talking on the cell phone while driving. Texting is commonly used by young adults, though many believe texting while driving decreases concentration and is unsafe. A majority report to texting while driving. Injury prevention and awareness programs are needed to decrease this behavior.

2012-06-01

The trauma prevention program at Geisinger Wyoming Valley (GWV) Medical Center in Wilkes-Barre, PA, has enlisted the assistance of an experienced paramedic and ED tech to spend part of his time targeting prevention education toward populations that have been experiencing high rates of traumatic injuries. While community outreach has long been a priority for the trauma prevention program, the new position is enabling GWV to boost the magnitude of its prevention efforts, and to reach out to referring facilities as well. Program administrators say a similar outreach effort aimed at EMS providers has strengthened relationships and helped to improve trauma care at the facility. The new trauma injury prevention outreach coordinator has focused his first efforts on fall prevention and curbing motor vehicle accidents among very young and very mature driving populations. Data from GWV's trauma registry suggest that its fall prevention efforts are having an effect. The incidence of falls among patients over the age 65 is down by about 10% at the facility since it began targeting education at the community's senior population. Administrators say a monthly lecture series aimed at the prehospital community has gone a long way toward nurturing ties with EMS providers. Called "EMS Night Out," the series covers a range of topics, but the most popular programs involve case reviews.

Effect of consecutive driving on accident risk: a comparison between passenger and freight train driving.

PubMed

Chang, Hsin-Li; Ju, Lai-Shun

2008-11-01

This study combined driver-responsible accidents with on-board driving hours to examine the effect of consecutive driving on the accident risk of train operations. The data collected from the Taiwan Railway Administration for the period 1996-2006 was used to compute accident rates for varied accumulated driving hours for passenger and freight trains. The results showed that accident risk grew with increased consecutive driving hours for both passenger and freight trains, and doubled that of the first hour after four consecutive hours of driving. Additional accident risk was found for freight trains during the first hour due to required shunting in the marshalling yards where there are complex track layouts and semi-automatic traffic controls. Also, accident risk for train driving increased more quickly over consecutive driving hours than for automobile driving, and accumulated fatigue caused by high working pressure and monotony of the working environment are considered to be the part of the reason. To prevent human errors accidents, enhancing safety equipment, driver training programs, and establishing a sound auditing system are suggested and discussed.

Motor Vehicle Trauma: An Unnecessary Disease

1987-01-01

The motor vehicle accident kills and maims more of our young people than any other affliction. Yet prevention of injuries and deaths from MVA receives less emphasis in medical education, medical publications and collective political action than the problem merits. In daily practice, there are numerous opportunities for prevention counselling, alcoholic driver case finding, and critical assessment of the privilege of driving. Within their community, family physicians can have input into some preventive programs. At government level, physicians should increase their pressure for legislative action to reduce MVA injuries and deaths. PMID:21267343

2015-06-19

Alcohol consumption is a risk factor for motor vehicle accidents in young drivers. Crashes associated with alcohol consumption typically have greater severity. This study examines the prevalence of driving under the influence among Spanish youth and tests the theory of reasoned action as a model for predicting driving under the influence. Participants included 478 Spanish university students aged 17-26 years. Findings indicated that alcohol was the substance most associated with impaired driving, and was involved in more traffic crashes. Men engage in higher levels of alcohol and other drug use, and perceived less risk in drunk driving (p < .01). The study confirms that alcohol use and driving under the influence of alcohol are highly prevalent in Spanish young people, and some gender differences exist in these behaviors (p < .01). Furthermore, the study confirms the validity of theory of reasoned action as a predictive model of driving under the influence of alcohol among youth in Spain (p < .001) and can help in the design of prevention programs.

2008-01-01

Unsafe driving and passenger behaviors place teens at increased risk for fatal and nonfatal crashes. This study evaluated the short-and long-term efficacy of the You Hold the Key (YHTK) Teen Driving Countermeasure. A two-page survey was completed by high school students at pretest, posttest, and long-term (6-month) posttest. YHTK was associated with significant immediate and long-term improvements in teen seatbelt use, safe driving, and perceived confidence in preventing drunk driving. Compared to pretests, students at immediate and long-term posttest more frequently wore seatbelts when driving or riding, required passengers to wear seatbelts, and limited the number of passengers to the number of seatbelts in the vehicle. Students were more likely at both posttests to avoid drinking and driving and to say no to riding with a friend who had been drinking. YHTK was associated with increases in safe teen driving and passenger behaviors. Success of YHTK is most notably due to its comprehensive nature. Future programs should consider comprehensive strategies when attempting to modify teen behaviors.

Smolak, Linda; Stein, Jonathan A

2006-06-01

This study examines the relationship of three sociocultural factors-media influence, peer teasing, and parent teasing/comments and three potential moderator variables-self-esteem, social comparison, and endorsement of male strength and athleticism-to drive for muscularity in middle school boys. There were 287 seventh and eighth grade boys who completed a questionnaire measuring these variables as well as body mass index (BMI) and pubertal status. Results indicated that media influence and male physical attributes endorsement were particularly important correlates of drive for muscularity. These findings have implications for programs designed to prevent body dissatisfaction among adolescent boys.

Collecting mortality data to drive real-time improvement in suicide prevention.

Ahmedani, Brian K; Coffey, Justin; Coffey, C Edward

2013-11-01

To evaluate the use of government mortality records compared with internally collected data to drive quality improvement in suicide prevention programs using suicide mortality data from the Perfect Depression Care initiative. Perfect Depression Care (PDC) is a quality improvement suicide prevention initiative within the Behavioral Health Services (BHS) division of the Henry Ford Health System. Eligible subjects were all patients who received services from BHS, were members of the health maintenance organization, and had a medical group physician during the 11-year study period. Mortality data were collected internally and from government-collected death records, and were linked to treatment utilization data from the medical record. The mean suicide rate was 96.6 per 100,000 during the 2-year baseline period (1999- 2000) and declined to 19.1 per 100,000 during the initiative (2002-2009) using both sources of data combined. We observed a similar statistically significant (P <.001) reduction in the suicide death rate using both the internal and government data sources. There were no significant differences between the 2 sources of data in the mean suicide rates for the baseline and intervention periods (P >.05). The data sources did differ in the capture of unique suicide deaths. Internally collected data were an effective measure of suicide deaths in the PDC initiative. A combination of internal and government-collected records may be most effective for future suicide prevention programs.

Parental Influence on Drinking Behaviors at the Transition to College: The Mediating Role of Perceived Friends' Approval of High-Risk Drinking.

PubMed

Rulison, Kelly L; Wahesh, Edward; Wyrick, David L; DeJong, William

2016-07-01

This study tested whether perceived parental approval of high-risk drinking is directly linked to alcohol-related outcomes or whether the link between perceived parental approval and these outcomes is mediated by perceived friends' approval of high-risk drinking. In fall 2009, 1,797 incoming first-year college students (49.7% female) from 142 U.S. colleges and universities completed a web-based survey before participating in an online substance use prevention program. The analytic sample included only 18- to 20-year-old freshmen students who had consumed alcohol in the past year. Students answered questions about perceived parental approval and perceived friends' approval of high-risk drinking. They also answered questions about their alcohol use (heavy episodic drinking, risky drinking behaviors), use of self-protective strategies (to prevent drinking and driving and to moderate alcohol use), and negative alcohol-related consequences (health, academic and work, social consequences, and drinking and driving). Mediation analyses controlling for the clustering of students within schools indicated that perceived parental approval was directly associated with more easily observable outcomes (e.g., academic- and work-related consequences, drinking and driving). Perceived friends' approval significantly mediated the link between perceived parental approval and outcomes that are less easily observed (e.g., alcohol use, health consequences). During the transition to college, parents may influence students' behaviors both directly (through communication) as well as indirectly (by shaping their values and whom students select as friends). Alcohol use prevention programs for students about to start college should address both parental and friend influences on alcohol use.

We review the "designated driver" concept and the current debate over its role in preventing alcohol-impaired driving. In our view, the focus on this strategy by broadcasters, the alcohol industry, and various public service groups has deflected attention from other alcohol-related problems that account for the vast majority of deaths and injuries associated with alcohol use. This focus has also distracted many public health advocates and policymakers from the bigger and more important jobs of increasing public awareness of the social, environmental, and economic factors that influence alcohol consumption and promoting debate on legislation and other public policy solutions to alcohol-impaired driving. As part of a comprehensive strategy, we strongly encourage a renewed focus on "sobriety checkpoints," strict enforcement of laws against alcohol sales to minors, alcohol advertising reform, increased excise taxes, and other public policy initiatives supported by the Surgeon General. These measures will curb underage and heavy alcohol consumption and will create a legal and social environment in which individuals are motivated to avoid impaired driving through several alternative strategies, including but not limited to the use of designated drivers.

Patients continue to suffer from pressure ulcers (PUs), despite implementation of evidence-based pressure ulcer (PU) prevention protocols. In 2009, Joint Commission Resources (JCR) and Hill-Rom created the Nurse Safety Scholar-in-Residence (nurse scholar) program to foster the professional development of expert nurse clinicians to become translators of evidence into practice. The first nurse scholar activity has focused on PU prevention. Four hospitals with established PU programs participated in the PU prevention implementation project. Each hospital's team completed an inventory of PU prevention program components and provided copies of accompanying documentation, along with prevalence and incidence data. Site visits to the four participating hospitals were arranged to provide opportunities for more in-depth analysis and support. Following the initial site visit, the project team at each hospital developed action plans for the top three barriers to PU program implementation. A series of conference calls was held between the site visits. Pressure Ulcer Program Gaps and Recommendations. The four hospitals shared common gaps in terms of limitations in staff education and training; lack of physician involvement; limited involvement of unlicensed nursing staff; lack of plan for communicating at-risk status; and limited quality improvement evaluations of bedside practices. Detailed recommendations were identified for addressing each of these gaps. these Recommendations for eliminating gaps have been implemented by the participating teams to drive improvement and to reduce hospital-acquired PU rates. The nurse scholars will continue to study implementation of best practices for PU prevention.

Prison privatization and HIV prevention in Australia.

PubMed

Cregan, J

Prison privatization is being increasingly discussed as an alternative that might help drive down the cost of corrections in Canada. An Australian conference recently addressed prison privatization. Australia has a long history with privatizing corrections and historically being the site of private penal colonies. Private and State-owned corporations own and manage Australian prisons and the balance of private and public sector activity within the prisons is discussed. HIV/AIDS care and prevention programs provide bleach distribution, education programs for staff and inmates, and safety training. Moral issues debating how much time and money is allocated to HIV/AIDS are addressed. Private operators of prisons have no financial incentive to educate, rehabilitate, or release prisoners.

The Centers for Disease Control reports that motor vehicle crashes (MVCs) are the leading cause of injury and death among U.S. teenagers, and disproportionately affect males. Among preventable causes of MVCs involving teenage drivers, distracted driving continues to be a serious public health problem. To describe gender differences in teenage drivers' self-perceptions of safe driving behaviors, and self-reported risk behaviors and distractions while driving. We prospectively surveyed teenage drivers from four high schools in Pennsylvania and New Jersey. Gender comparisons were made between self-reported perceptions and self-reported driving behaviors. Descriptive statistics and chi-squared testing were used in data analyses; significance was set at p < 0.05. Seven hundred fifty-six high school teenage drivers completed surveys. Males (52%) and females (48%) were equally distributed; 32% of males reported that they were extremely safe drivers, whereas only 18% of females reported that they were extremely safe drivers (p < 0.001). Significantly more females (91%) compared to males (77%) reported always wearing their seatbelts (p < 0.001). Female drivers were more likely than male drivers to self-report that they always make their passengers wear a seat belt (76% vs. 63%, p < 0.001). A higher proportion of males reported using their cell phones while driving, compared to females (68% vs. 56%, p = 0.004), and 42% of males reported texting while driving, compared to 34% of females (p = 0.037). Teenage male drivers perceive themselves to be safe drivers, but report engaging in more distracted driving and risky behaviors compared to females. These results suggest that there is an opportunity for gender-specific educational and injury prevention programs for teen drivers. Copyright © 2015 Elsevier Inc. All rights reserved.

Can technology and the media help reduce dysfunctional parenting and increase engagement with preventative parenting interventions?

In an evaluation of the television series "Driving Mum and Dad Mad," 723 families participated and were randomly assigned to either a standard or technology enhanced viewing condition (included additional Web-support). Parents in both conditions reported significant improvements from pre- to postintervention in their child's behavior, dysfunctional parenting, parental anger, depression, and self-efficacy. Short-term improvements were maintained at 6-months follow-up. Regressions identified predictors of program outcomes and level of involvement. Parents who watched the entire series had more severe problems at preintervention and high sociodemographic risk than parents who did not watch the entire series. Few sociodemographic, child, or parent variables assessed at preintervention predicted program outcomes or program engagement, suggesting that a wide range of parents from diverse socioeconomic status benefited from the program. Media interventions depicting evidence-based parenting programs may be a useful means of reaching hard to engage families in population-level child maltreatment prevention programs.

Driving after the consumption of alcohol represents a significant problem globally. Individual prevention countermeasures such as personalized mobile app aimed at preventing such behavior are widespread, but there is little research on their accuracy and evidence base. There has been no known assessment investigating the quality of such apps. This study aimed to determine the quality and accuracy of apps for drink driving prevention by conducting a review and evaluation of relevant mobile apps. A systematic app search was conducted following PRISMA guidelines. App quality was assessed using the Mobile App Rating Scale (MARS). Apps providing blood alcohol calculators (hereafter "calculators") were reviewed against current alcohol advice for accuracy. A total of 58 apps (30 iOS and 28 Android) met inclusion criteria and were included in the final analysis. Drink driving prevention apps had significantly lower engagement and overall quality scores than alcohol management apps. Most calculators provided conservative blood alcohol content (BAC) time until sober calculations. None of the apps had been evaluated to determine their efficacy in changing either drinking or driving behaviors. This novel study demonstrates that most drink driving prevention apps are not engaging and lack accuracy. They could be improved by increasing engagement features, such as gamification. Further research should examine the context and motivations for using apps to prevent driving after drinking in at-risk populations. Development of drink driving prevention apps should incorporate evidence-based information and guidance, lacking in current apps.

Objective: The primary aim of this article is to assess young dirvers' gender differences in the associations between substance use/environmental influences and high-risk driving behavior. Method: We determine the association of 12th-grade self-reported substance use/environmental influences with high-risk driving behavior as quantified by the number of offenses, serious offenses, crashes, and single-vehicle crashes on state driving records during subjects' (N = 3,607; 51% male) first 4 years of licensure. Results: The associations between high-risk driving and substance use/environmental influences were generally stronger among women than among men. When matched by substance-use profiles, women had fewer risky-driving incidents than men. Conclusions: The results indicate that young women who exhibit high-risk driving behavior deviate more from the general population of young women with respect to alcohol use, alcohol misuse, and marijuana use than high-risk-driving young men differ from other young men. In addition, findings indicate that even if young men and women were to eventually have equal levels of substance use, women would likely retain their lower-risk driving profiles. These findings suggest the need for (1) future research to understand the differential associations, and (2) prevention programs that consider these gender differences. PMID:16562407

Among the factors associated with driving safety, sleep-related variables constitute a leading cause of road accidents. Circadian fluctuations of driver's somnolence has been previously linked to road safety. However, the role of chronotype in this relationship has been poorly investigated. Thus, the aim of the present work was to address whether driving performance is influenced by circadian patterns, in turn modulated by the driver's chronotype and the time of day (i.e. synchrony effect). We assessed 47 healthy young adults with specific chronotypes in several simulated driving sessions, both in the morning and in the evening. We collected driving performance data, along with self-reported levels of activation prior to each driving session and other sleep-related variables. Participants drove less safely when testing times took place outside their optimal time of day, as determined by their chronotype and confirmed by self-reported levels of activation. These differences were more pronounced in the morning, when morning types shown a better driving performance. Our results suggest that chronotype plays an important role as a modulator of the relationship between the time of day and driving safety. Therefore, it is necessary to acknowledge this variable in theoretical models of driving behavior, and for the improvement of occupational accidents prevention programs.

Tumor suppressor roles of CENP-E and Nsl1 in Drosophila epithelial tissues.

Clemente-Ruiz, Marta; Muzzopappa, Mariana; Milán, Marco

2014-01-01

Depletion of spindle assembly checkpoint (SAC) genes in Drosophila epithelial tissues leads to JNK-dependent programmed cell death and additional blockade of the apoptotic program drives tumorigenesis. A recent report proposes that chromosomal instability (CIN) is not the driving force in the tumorigenic response of the SAC-deficient tissue, and that checkpoint proteins exert a SAC-independent tumor suppressor role. This notion is based on observations that the depletion of CENP-E levels or prevention of Bub3 from binding to the kinetochore in Drosophila tissues unable to activate the apoptotic program induces CIN but does not cause hyperproliferation. Here we re-examined this proposal. In contrast to the previous report, we observed that depletion of CENP-E or Nsl1-the latter mediating kinetochore targeting of Bub3-in epithelial tissues unable to activate the apoptotic program induces significant levels of aneuploidy and drives tumor-like growth. The induction of the JNK transcriptional targets Wingless, a mitogenic molecule, and MMP1, a matrix metaloproteinase 1 involved in basement membrane degradation was also observed in these tumors. An identical response of the tissue was previously detected upon depletion of several SAC genes or genes involved in spindle assembly, chromatin condensation, and cytokinesis, all of which have been described to cause CIN. All together, these results reinforce the role of CIN in driving tumorigenesis in Drosophila epithelial tissues and question the proposed SAC-independent roles of checkpoint proteins in suppressing tumorigenesis. Differences in aneuploidy rates might explain the discrepancy between the previous report and our results.

Distracted driving (talking and/or texting) is a growing public safety problem, with increasing incidence among adult drivers. The aim of this study was to identify the incidence of distracted driving (DD) among health care providers and to create awareness against DD. We hypothesized that distracted driving is prevalent among health care providers and a preventive campaign against distracted driving would effectively decrease distracted driving among health care providers. We performed a 4-phase prospective interventional study of all health care providers at our level 1 trauma center. Phase 1: one week of pre-intervention observation; phase 2: one week of intervention; phase 3: one week of postintervention observation; and phase 4: one week of 6 months of postintervention observation. Observations were performed outside employee parking garage at the following time intervals: 6:30-8:30 a.m., 4:40-5:30 p.m., and 6:30-7:30 p.m. Intervention included an e-mail survey, pamphlets and banners in the hospital cafeteria, and a postintervention survey. Hospital employees were identified with badges and scrubs, employees exiting through employee gate, and parking pass on the car. Outcome measure was incidence of DD pre, post, and 6 months postintervention. A total of 15,416 observations (pre: 6,639, post: 4,220, 6 months post: 4,557) and 520 survey responses were collected. The incident of DD was 11.8% among health care providers. There was a significant reduction in DD in each time interval of observation between pre- and postintervention. On subanalysis, there was a significant decrease in talking (P = .0001) and texting (P = .01) while driving postintervention compared to pre-intervention. In the survey, 35.5% of respondents admitted to DD and 4.5% respondents were involved in an accident due to DD. We found that 77% respondents felt more informed after the survey and 91% respondents supported a state legislation against DD. The reduction in the incidence of DD postintervention was sustained even at 6-month follow-up. There was a 32% reduction in the incidence of distracted driving postintervention, which remained low even at 6-month follow-up. Implementation of an effective injury prevention campaign could reduce the incidence of distracted driving nationally.

Hypoglycemia is a frequent phenomenon in people being treated for diabetes mellitus, which can acutely disrupt driving performance. For the benefit of personal and public traffic safety, we decided to identify successful diabetes-related (SDR) behaviors to support safe driving for people with diabetes, from the perspective of experiential experts with diabetes mellitus. Experiential experts are people who can manage their own illness and conditions by developing expertise relevant to maintaining health and countering illness, and who are able to use this expertise to the benefit of peers. The aim of our study was to objectify and systematize experiential expertise in terms of SDR behaviors, based on reports by experiential experts, to support safe driving for people with type 1 and type 2 diabetes mellitus. The emphasis was on preventing hypoglycemia as a short-term complication during driving. We performed a mixed-methods study involving (i) semi-structured in-depth interviews with 33 experiential experts with diabetes mellitus from the Dutch Diabetes Association (DVN; Diabetesvereniging Nederland), in order to identify SDR behaviors regarding safe driving, and (ii) a validation study by means of a survey among a panel of 98 experiential experts (peers) from the DVN, to determine the extent to which they agreed with the communicability, importance, and feasibility of these behaviors for drivers with diabetes mellitus. We identified a comprehensive set of 11 SDR behaviors, differentiated into seven general and four specific behaviors, to support safe driving. The general behaviors concern the following topics: (i) acquiring knowledge and information; (ii) acquiring and using self-measuring of blood glucose (SMBG) equipment; (iii) knowing one's physical response pattern; (iv) obtaining knowledge about the medication used; (v) preventing long-term eye complications; (vi) influencing factors that can affect blood glucose; and (vii) renewal procedure for driving license. The four specific behaviors refer to the following topics: (i) measures to be taken before driving; (ii) responding effectively to hypoglycemia while driving; (iii) informing and instructing passengers; and (iv) preventing hypoglycemia in drivers with type 2 diabetes mellitus not using SMBG equipment. Key factors for safe driving proved to be the ability of drivers to anticipate and respond effectively to hypoglycemia while driving and to inform and instruct fellow passengers. Participants of the validation survey agreed to a considerable degree with the communicability, importance, and feasibility of these behaviors to support safe driving for people with diabetes mellitus. This study resulted in the identification and description of SDR behaviors to support safe driving. It proved possible to operationalize experiential expertise in terms of such behaviors. The next step is to have these behaviors validated by professional care providers in the field of diabetes, followed by translation into recommendations in self-management programs.

Methodological and Design Considerations in Evaluating the Impact of Prevention Programs on Violence and Related Health Outcomes.

PubMed

Massetti, Greta M; Simon, Thomas R; Smith, Deborah Gorman

2016-10-01

Drawing on research that has identified specific predictors and trajectories of risk for violence and related negative outcomes, a multitude of small- and large-scale preventive interventions for specific risk behaviors have been developed, implemented, and evaluated. One of the principal challenges of these approaches is that a number of separate problem-specific programs targeting different risk areas have emerged. However, as many negative health behaviors such as substance abuse and violence share a multitude of risk factors, many programs target identical risk factors. There are opportunities to understand whether evidence-based programs can be leveraged for potential effects across a spectrum of outcomes and over time. Some recent work has documented longitudinal effects of evidence-based interventions on generalized outcomes. This work has potential for advancing our understanding of the effectiveness of promising and evidence-based prevention strategies. However, conducting longitudinal follow-up of established interventions presents a number of methodological and design challenges. To answer some of these questions, the Centers for Disease Control and Prevention convened a panel of multidisciplinary experts to discuss opportunities to take advantage of evaluations of early prevention programs and evaluating multiple long-term outcomes. This special section of the journal Prevention Science includes a series of papers that begin to address the relevant considerations for conducting longitudinal follow-up evaluation research. This collection of papers is intended to inform our understanding of the challenges and strategies for conducting longitudinal follow-up evaluation research that could be used to drive future research endeavors.

Changing the Direction of Suicide Prevention in the United States.

It is axiomatic that the goal of suicide prevention is the prevention of suicide. Yet in spite of significant efforts to this end since the middle of the last century, and most notably in the last decade, the rate of suicide in the U.S. has not declined; rather, it has increased. To address this issue, Suicide Awareness Voices of Education (SAVE) brought together leading prevention specialists from other public health problems where successes have been achieved, representatives from countries where suicide rates have declined, and U.S. based suicide prevention researchers and program directors, to "think outside the box" and propose innovative, scalable approaches that might better drive success in achieving desired results from U.S. suicide prevention efforts. The recommendations should challenge our preconceptions and force us outside our own mental constraints to broaden our perspectives and suggest catalysts for real change in suicide prevention. © 2016 The American Association of Suicidology.

Self-Estimation of Blood Alcohol Concentration: A Review

PubMed Central

Aston, Elizabeth R.; Liguori, Anthony

2013-01-01

This article reviews the history of blood alcohol concentration (BAC) estimation training, which trains drinkers to discriminate distinct BAC levels and thus avoid excessive alcohol consumption. BAC estimation training typically combines education concerning alcohol metabolism with attention to subjective internal cues associated with specific concentrations. Estimation training was originally conceived as a component of controlled drinking programs. However, dependent drinkers were unsuccessful in BAC estimation, likely due to extreme tolerance. In contrast, moderate drinkers successfully acquired this ability. A subsequent line of research translated laboratory estimation studies to naturalistic settings by studying large samples of drinkers in their preferred drinking environments. Thus far, naturalistic studies have provided mixed results regarding the most effective form of BAC feedback. BAC estimation training is important because it imparts an ability to perceive individualized impairment that may be present below the legal limit for driving. Consequently, the training can be a useful component for moderate drinkers in drunk driving prevention programs. PMID:23380489

Over the past two decades, the Centers for Disease Control and Prevention (CDC) has been a key contributor to the growing public health effort to prevent violence. Although CDC and its partners are proud of their many successes, much work remains to be done. Violence continues to be a leading cause of death worldwide for people aged 15-44. Moreover, although many forms of violence garner national concern and resources, much more violence occurs in private domains and receives less attention. These hidden health hazards silently drain our nation's human, economic, and health resources. In this paper, we highlight the current efforts of the Division of Violence Prevention (DVP), housed within CDC's National Center for Injury Prevention and Control (NCIPC), to use a public health approach to the prevention of one key hidden health hazard: violence against women (VAW). Building from a recently developed strategic plan and a research agenda, we explain how four core public health principles--emphasizing primary prevention, advancing the science of prevention, translating science into effective programs, and building on the efforts of others--drive current programmatic activities in VAW prevention. Several current programs and projects are described. Finally, we conclude with recommendations for future prevention work by deepening our vision of leadership, expanding our partnerships, pursuing comprehensive approaches, and using evidence-based strategies.

Emotional abilities as predictors of risky driving behavior among a cohort of middle aged drivers.

2012-03-01

The aim of this study is to analyze the relationship between emotional abilities and the influence of this relationship on self reported drivers' risky attitudes. The risky driving attitudes and emotional abilities of 177 future driving instructors were measured. The results demonstrate that risky attitudes correlate negatively with emotional abilities. Regression analysis showed that adaptability and interpersonal abilities explained the differences observed in the global risk attitude index. There were some differences in the specific risk factors. The variability observed in the speed and distraction and fatigue factors could also be explained by interpersonal and adaptability abilities. Nevertheless the tendency to take risks was explained by stress management and also interpersonal components. Emotional abilities have the weakest relation with alcohol and drugs factor, and in this case the variability observed was explained by the adaptability component. The results obtained highlight the importance take off including emotional abilities in prevention programs to reduce risky driving behaviors. Copyright © 2011 Elsevier Ltd. All rights reserved.

Some people without independent mobility are candidates for powered mobility but are unable to use a traditional power wheelchair joystick. This proof-of-concept study tested and further developed an innovative method of driving power wheelchairs for people whose impairments prevent them from operating commercial wheelchair controls. Our concept, Self-referenced Personal Orthotic Omni-purpose Control Interface (SPOOCI), is distinguished by referencing the control sensor not to the wheelchair frame but instead to the adjacent proximal lower-extremity segment via a custom-formed orthosis. Using a descriptive case-series design, we compared the pre–post functional power wheelchair driving skill data of 4 participants, measured by the Power Mobility Program, using descriptive analyses. The intervention consisted of standard-care power wheelchair training during 12 outpatient occupational or physical therapy sessions. All 4 participants who completed the 12-wk intervention improved their functional power wheelchair driving skills using SPOOCI, but only 3 were deemed safe to continue with power wheelchair driving.

2004-03-01

The current study examined whether a social desirability response bias is a source of measurement error in prevention research. Six hundred and seventy-seven female students in Grade 7 (n = 345) and Grade 8 (n = 332) were divided into either an intervention condition, in which participants watched a videotape promoting body acceptance and discouraging dieting and then discussed issues related to the video, or a control condition. Questionnaires were completed at baseline, postintervention, and at 1-month follow-up. Social desirability scores were correlated at a low but significant level with baseline body dissatisfaction, drive for thinness, bulimic tendencies, intention to diet, and size discrepancy for intervention participants. Social desirability did not correlate significantly with change over time in the outcome measures. The findings suggested that changes in girls' self-reports related to a prevention program were relatively free of social desirability response bias. Copyright 2004 by Wiley Periodicals, Inc.

Warden, Harry K.; Jenkins, Terro J.

2011-01-01

A drive mechanism enables a socket-type wrench to rotate a shaft and prevents accidental rotation of the shaft when the wrench is not coupled to the shaft. In the original intended application, the shaft would be part of an attachment mechanism on a spacecraft, and the purpose to be served by the drive is to prevent back-driving of the shaft by launch vibrations while enabling an astronaut equipped with the appropriate wrench to actuate the shaft while in orbit. The design could also be adapted to terrestrial applications in which it is necessary to prevent rotational back-driving. The mechanism includes a gear near the tip of the shaft, and a drive nut that constitutes the tip of the shaft. The gear and drive nut are positioned in a recess in a housing. The recess is sized to receive the wrench socket that mates with the drive nut. Also contained in the housing are four linkages that include pins that are spring-loaded into engagement with the gear to prevent rotation of the shaft. When the wrench socket is inserted in the recess, it pushes on the linkages in such a manner as to disengage the pins from the gear.

Why don't northern American solutions to drinking and driving work in southern America?

PubMed

Pechansky, Flavio; Chandran, Aruna

2012-07-01

While individual studies from several South American countries have shown driving while intoxicated to be a problem, there are no objective systematically collected alcohol-associated driving data obtained in most South American countries. This limits their ability to implement and enforce targeted prevention strategies, evaluate whether proven prevention efforts from North America (particularly the United States and Canada) can be transferred to the South, and to sustain momentum for the improvement of road safety by demonstrating that previously implemented legal and policy changes are effective. The aim of this paper is to discuss the abysmal differences that exist between northern and southern American countries regarding the current status of driving while intoxicated prevention strategies-their implementation, impacts and effects-using Brazil as a case example. We propose a three-pronged approach to close this northern-southern American gap in driving while intoxicated prevention and intervention: (a) systematic collection on road traffic crash/injury/death as well as risk factor data, (b) passage of laws without loopholes requiring compliance with blood alcohol concentration testing and (c) provision of appropriate training and equipment to the police in concomitance with vigilant enforcement. Resources and energies must be put towards data collection, implementation of prevention strategies and enforcement in order to decrease the unacceptably high rates of these preventable driving while intoxicated deaths. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

The billions of people with latent tuberculosis infection serve as the seedbeds for future cases of active tuberculosis. Virtually all episodes of tuberculosis disease are preceded by a period of asymptomatic Mycobacterium tuberculosis infection; therefore, identifying infected individuals most likely to progress to disease and treating such subclinical infections to prevent future disease provides a critical opportunity to interrupt tuberculosis transmission and reduce the global burden of tuberculosis disease. Programs focusing on single strategies rather than comprehensive programs that deliver an integrated arsenal for tuberculosis control may continue to struggle. Tuberculosis preventive therapy is a poorly utilized tool that is essential for controlling the reservoirs of disease that drive the current epidemic. Comprehensive control strategies that combine preventive therapy for the most high-risk populations and communities with improved case-finding and treatment, control of transmission and health systems strengthening could ultimately lead to worldwide tuberculosis elimination. This paper outlines challenges to implementation of preventive therapy and provides pragmatic suggestions for overcoming them. It further advocates for tuberculosis preventive therapy as the core of a renewed global focus to implement a comprehensive epidemic control strategy that would reduce new tuberculosis cases to elimination targets. This strategy would be underpinned by accelerated research to further understand the biology of subclinical tuberculosis infections, develop novel diagnostics, and drug regimens specifically for subclinical tuberculosis infection, strengthen health systems, community engagement, and enhance sustainable large scale implementation of preventive therapy programs.

This article presents an evaluation of Common Ground, a media campaign-supported prevention program featuring increased enforcement, decreased alcohol access, and other environmental management initiatives targeting college student drinking. Phase 1 of the media campaign addressed student resistance to environmentally focused prevention by reporting majority student support for alcohol policy and enforcement initiatives. Phase 2 informed students about state laws, university policies, and environmental initiatives. We conducted student telephone surveys, with samples stratified by gender and year in school, for 4 consecutive years at the intervention campus and 3 years at a comparison campus. We did a series of one-way between-subjects analyses of variance and analyses of covariance, followed by tests of linear trend and planned comparisons. Targeted outcomes included perceptions of enforcement and alcohol availability, alcohol use, and alcohol-impaired driving. We examined archived police reports for student incidents, primarily those resulting from loud parties. There were increases at the intervention campus in students' awareness of formal alcohol-control efforts and perceptions of the alcohol environment, likelihood of apprehension for underage drinking, consequences for alcohol-impaired driving, and responsible alcohol service practices. There were decreases in the perceived likelihood of other students' negative behavior at off-campus parties. Police-reported incidents decreased over time; however, perceived consequences for off-campus parties decreased. No changes were observed for difficulty finding an off-campus party, self-reported alcohol use, or alcohol-impaired driving. The intervention successfully altered perceptions of alcohol enforcement, alcohol access, and the local alcohol environment. This study provides important preliminary information to researchers and practitioners engaged in collaborative prevention efforts in campus communities.

Current CRISPR gene drive systems are likely to be highly invasive in wild populations.

Noble, Charleston; Adlam, Ben; Church, George M; Esvelt, Kevin M; Nowak, Martin A

2018-06-19

Recent reports have suggested that self-propagating CRISPR-based gene drive systems are unlikely to efficiently invade wild populations due to drive-resistant alleles that prevent cutting. Here we develop mathematical models based on existing empirical data to explicitly test this assumption for population alteration drives. Our models show that although resistance prevents spread to fixation in large populations, even the least effective drive systems reported to date are likely to be highly invasive. Releasing a small number of organisms will often cause invasion of the local population, followed by invasion of additional populations connected by very low rates of gene flow. Hence, initiating contained field trials as tentatively endorsed by the National Academies report on gene drive could potentially result in unintended spread to additional populations. Our mathematical results suggest that self-propagating gene drive is best suited to applications such as malaria prevention that seek to affect all wild populations of the target species. © 2018, Noble et al.

Volunteers' Experiences Delivering a Community-University Chronic Disease Health Awareness Program for South Asian Older Adults.

Volunteers and voluntary organizations can connect preventative health care programs to communities and may play an important role in addressing the health needs of older adults. Despite this, tensions may exist in the structures that drive volunteers and voluntary organizations representing immigrant communities to provide unpaid labour to augment and supplement health care services. Furthermore, organizational challenges may exist for community agencies relying on volunteers to sustain a health screening and education program. The intervention program was led by one voluntary agency specifically for South Asian communities in partnership with the university and five local organizations. This paper draws on volunteer surveys (n = 22) and key informant interviews (n = 12) to detail volunteer experiences providing this intervention. Volunteers were university students and other community volunteers. A total of 810 adults participated in the intervention within the Greater Toronto Area, Ontario, Canada between October 2014 and June 2016. We found that volunteers often used their experience as a 'stepping stone' position to other education or work. They also gained from the knowledge and used it to educate themselves and their family members and friends. This paper provides a critical reflection on the role of volunteers in a preventative and educational healthcare intervention program for older adults from the South Asian community. Tensions exist when relying on volunteer labour for the implementation of preventative community health care programming and must be explored to ensure program sustainability as well as equity within the health care system.

Traffic accidents are the leading cause of hospitalization in adolescence, with the 18-24-year-old age group accounting for 23% of deaths by traffic accidents. Recurrence rate is also high. One in four teenagers will have a relapse within the year following the first accident. Cognitive impairments known in adolescence could cause risky behaviors, defined as repetitive engagement in dangerous situations such as road accidents. Two categories of factors seem to be associated with traffic accidents: (1) factors specific to the traffic environment and (2) "human" factors, which seem to be the most influential. Moreover, the establishment of a stronger relation to high speed driving increases traffic accident risks and can also be intensified by sensation seeking. Other factors such as substance use (alcohol, drugs, and "binge drinking") are also identified as risk factors. Furthermore, cell phone use while driving and attention deficit disorder with or without hyperactivity also seem to be important risk factors for car accidents. The family environment strongly influences a young person's driving behavior. Some interventional driving strategies and preventive measures have reduced the risk of traffic accidents among young people, such as the graduated driver licensing program and advertising campaigns. So far, few therapeutic approaches have been implemented. Reason why, we decided to set up an innovative strategy consisting of a therapeutic postaccident group intervention, entitled the ECARR2 protocol, to prevent recurrence among adolescents and young adults identified at risk, taking into account the multiple risk factors.

Evidence for effective falls prevention interventions in acute wards is limited. One reason for this may be suboptimal program implementation. This study aimed to identify perceived barriers and enablers of the implementation of the 6-PACK falls prevention program to inform the implementation in a randomised controlled trial. Strategies to optimise successful implementation of 6-PACK were also sought. A mixed-methods approach was applied in 24 acute wards from 6 Australian hospitals. Participants were nurses working on participating wards and senior hospital staff including Nurse Unit Managers; senior physicians; Directors of Nursing; and senior personnel involved in quality and safety or falls prevention. Information on barriers and enablers of 6-PACK implementation was obtained through surveys, focus groups and interviews. Questions reflected the COM-B framework that includes three behaviour change constructs of: capability, opportunity and motivation. Focus group and interview data were analysed thematically, and survey data descriptively. The survey response rate was 60% (420/702), and 12 focus groups (n = 96 nurses) and 24 interviews with senior staff were conducted. Capability barriers included beliefs that falls could not be prevented; and limited knowledge on falls prevention in patients with complex care needs (e.g. cognitive impairment). Capability enablers included education and training, particularly face to face case study based approaches. Lack of resources was identified as an opportunity barrier. Leadership, champions and using data to drive practice change were recognised as opportunity enablers. Motivation barriers included complacency and lack of ownership in falls prevention efforts. Motivation enablers included senior staff articulating clear goals and a commitment to falls prevention; and use of reminders, audits and feedback. The information gained from this study suggests that regular practical face-to-face education and training for nurses; provision of equipment; audit, reminders and feedback; leadership and champions; and the provision of falls data is key to successful falls prevention program implementation in acute hospitals.

Latinos are disproportionately impacted by drinking and driving arrests and alcohol-related fatal crashes. Why, and how, these disparities occur remains unclear. The neighborhood environments that recent Latino immigrants encounter in their host communities can potentially influence health behaviors over time, including the propensity to engage in drinking and driving. This cross-sectional study utilizes a sample of 467 documented and undocumented adult recent Latino immigrants in the United States to answer the following research questions: (a) How do neighborhood-level factors, combined with social support, impact drinking and driving risk behaviors?; and (b) Does acculturative stress moderate the effects of those associations? Results indicate neighborhood-level factors (informal social control and social capital) have protective effects against drinking and driving risk behaviors via the mediating mechanism of social support. Acculturative stress moderated associations between neighborhood informal social control and social support, whereby the protective effects of informal social control on social support were not present for those immigrants with higher levels of acculturative stress. Our findings contribute to the limited knowledge of drinking and driving among Latino immigrants early in the immigration process and suggest that, in the process of developing prevention programs tailored to Latino immigrants, greater attention must be paid to neighborhood-level factors.

Drowsy driving is a serious public health concern which is often difficult for individual drivers to identify. While it is important for drivers to understand the causes of drowsy driving, there is still insufficient scientific knowledge and public education to prevent drowsy driving. As a result, the AASM is calling upon institutions and policy makers to increase public awareness and improve education on the issue, so our society can better recognize and prevent drowsy driving. The AASM has adopted a position statement to educate both healthcare providers and the general public about drowsy driving risks and countermeasures. © 2015 American Academy of Sleep Medicine.

Positive self-esteem, emotional well-being, school achievements and family connectedness are considered protective factors against health-compromising behaviors. This study examined the effect of an interactive, community-based, media literacy and dissonance wellness program, In Favor of Myself, on the self-image, body image, eating attitudes and behavior of young adolescents. A preliminary cohort study was conducted among 972 program participants who did not take part in the controlled trial. Over 75% of participants said they would recommend the program to their friends. A controlled trial was conducted to evaluate program acceptability, efficacy and effectiveness among 259 participants (210 in the intervention group and 49 in the control group), aged 12-14 years, who completed questionnaires during at least two assessment times. Program materials were provided, along with leaders' training, in order to ensure quality program delivery and creation of a wide network of committed program leaders. The program significantly reduced drive for thinness and self-worth contingent upon others' approval, the gap between current body figure and ideal figure, and the impact of mood on girls' self-image. Superiority was found among those participating in the intervention group with respect to recognizing media strategies, the influence of media on desire to change, and the influence of appearance on self-confidence and drive for thinness. In Favor of Myself shows promising results for strengthening adolescents' ability to cope with the challenges of their life stage. Suggestions for improving In Favor of Myself are presented.

While the number of motor vehicle crashes has declined over the years, crashes resulting from distracted driving are increasing in the United States resulting in significant morbidity and mortality. The national public seems to be aware of the dangers associated with using technology while driving, but continues to engage in this dangerous behaviour, and may be unaware of or underestimate the impact of cell phone use on their own driving performance. Problems associated with distracted driving are not limited to novice or teenage drivers; multifaceted universal prevention efforts aimed at impacting large segments of the population may have the greatest impact. Legislation limiting drivers' cell phone use has had little impact, possibly due to low regulation and enforcement. Behaviour change programmes, improved vehicle safety, and public awareness campaigns have been developed as potential preventive efforts to reduce accidents caused by distracted drivers.

After the launch of the US President's Emergency Plan for AIDS Relief in 2003, it became evident that inadequate laboratory systems and services would severely limit the scale-up of human immunodeficiency virus infection prevention, care, and treatment programs. Thus, the Office of the US Global AIDS Coordinator, Centers for Disease Control and Prevention, and Becton, Dickinson and Company developed a public-private partnership (PPP). Between October 2007 and July 2012, the PPP combined the competencies of the public and private sectors to boost sustainable laboratory systems and develop workforce skills in 4 African countries. Key accomplishments of the initiative include measurable and scalable outcomes to strengthen national capacities to build technical skills, develop sample referral networks, map disease prevalence, support evidence-based health programming, and drive continuous quality improvement in laboratories. This report details lessons learned from our experience and a series of recommendations on how to achieve successful PPPs. PMID:27025696

Violence impacts the lives of children on a daily basis. In their communities, they witness drive-by shootings, drug deals, and violence in their schools while many endure abuse, neglect, and violent behavior in their homes. Because the traumatizing impact of such exposure disrupts a child's ability to concentrate and learn, the Dallas Independent School District (ISD) sought content expertise to develop a training vehicle for school district professionals. The program aimed to raise the awareness of educators to problems related to domestic violence and the myriad of circumstances at home and in the community that lead to exposure to violence. Approximately 15,000 faculty and staff of Dallas ISD were educated in the identification, intervention, and prevention of exposure to violence. Referrals and inquiries related to abuse have increased (approximately 70%) while the city of Dallas has witnessed a drop in the number of domestic violence and child abuse offenses.

In June 2011, Texas enacted Senate Bill 7, which mandates a Medicaid quality-based outcomes payment program on the basis of a common set of outcomes that apply to all types of provider systems including hospitals, managed care plans, medical homes, managed long-term care plans, and Accountable Care Organizations. The quality-based outcome measures focus on potentially preventable events (services) such as preventable admissions and readmissions that result in unnecessary expense, patient inconvenience, and risk of complications. The payment adjustments relate to a provider system's effectiveness in reducing the rate at which potentially preventable events occur. The program envisioned by Texas Medicaid is one that is administratively simple, establishes the right financial incentives to drive delivery system improvement, and does not intrude on the provider practice or the patient. Rather than imposing a series of processes that must be followed or require rigid adherence to standardized protocols, the payment adjustments are based on risk-adjusted comparisons of the rate of potentially preventable events for an individual provider systems to an empirically derived performance standard such as the state average. This article proposes a payment system design that can meet the ambitious objectives of the Texas legislation.

Risky driving is a common cause of traffic accidents and injuries. However, there is no clear evidence of how difficulties in emotion regulation contribute to risky driving behavior, particularly in small post-Soviet countries. The present study aimed to investigate the relationship between difficulties in emotion regulation and self-reported risky driving behavior in a sample of Lithuanian drivers. A total of 246 nonprofessional Lithuanian drivers participated in a cross-sectional survey. Difficulties in emotion regulation were assessed using the Difficulties in Emotion Regulation Scale (DERS; Gratz and Roemer 2004), and risky driving behavior was assessed using the Manchester Driver Behaviour Questionnaire (DBQ; Lajunen et al. 2004). Males scored higher than females in aggressive violations and ordinary violations. Females scored higher for the nonacceptance of emotional responses, whereas males had more difficulties with emotional awareness than females. More difficulties in emotion regulation were positively correlated with driving errors, lapses, aggressive violations, and ordinary violations for both males and females. Structural equation modeling showed that difficulties in emotion regulation explained aggressive and ordinary violations more clearly than lapses and errors. When controlling for interactions among the distinct regulation difficulties, difficulties with impulse control and difficulties engaging in goal-directed behavior predicted risky driving. Furthermore, nonacceptance of emotional responses and limited access to emotion regulation strategies were related to less violations and more driving errors. Emotion regulation difficulties were associated with the self-reported risky driving behaviors of Lithuanian drivers. This provides useful hints for improving driver training programs in order to prevent traffic injuries.

Along with laser-indirect (x-ray)-drive and magnetic-drive target concepts, laser direct drive is a viable approach to achieving ignition and gain with inertial confinement fusion. In the United States, a national program has been established to demonstrate and understand the physics of laser direct drive. The program utilizes the Omega Laser Facility to conduct implosion and coupling physics at the nominally 30-kJ scale and laser–plasma interaction and coupling physics at the MJ scale at the National Ignition Facility. This paper will discuss the motivation and challenges for laser direct drive and the broad-based program presently underway in the United States.

The American College of Preventive Medicine (ACPM) is providing a set of recommendations designed to reduce the morbidity and mortality associated with distractions due to texting while driving. According to the National Highway Traffic Safety Administration, 12% of all fatal crashes involving at least one distracted driver are estimated to be related to cell phone use while driving. Given the combination of visual, manual, and cognitive distractions posed by texting, this is an issue of major public health concern for communities. Therefore, the ACPM feels it is timely to discuss this issue and provide the following recommendations: 1. Encourage state legislatures to develop and pass legislation banning texting while driving, while simultaneously implementing comprehensive and dedicated law enforcement strategies including penalties for these violations. Legislatures should establish a public awareness campaign regarding the dangers of texting while driving as an integral part of this legislation. 2. Promote further research into the design and evaluation of educational tools regarding texting while driving that can be incorporated into the issuance of driver’s licenses. 3. Provide primary care providers with the appropriate tools to educate patients of all ages. 4. Conduct additional studies investigating the risks associated with cell phone usage while driving, particularly texting, with motor vehicle crashes.

Get the Message: A Teen Distracted Driving Program.

PubMed

Adeola, Ruth; Omorogbe, Ashleigh; Johnson, Abree

Elimination of distracted driving is becoming a public health priority. Each day, an average of 8 people are killed due to a distracted driver in the United Sates. Although all drivers are at risk, research has indicated that teenage drivers are overrepresented in motor vehicle crashes due to distracted driving. Teenage drivers are hindered by limited driving experience, and the illusion of invincibility is a common phase in social and cognitive adolescent development. "Get the Message: A Teenage Distracted Driving Program" was established at the R Adams Cowley Shock Trauma Center to identify, define, and measure the factors that contribute to distracted driving in teens. A convenience sample of 1,238 teenagers in this study represented all 50 states in the United States, the District of Columbia, Puerto Rico, Canada, and 21 other countries. At the beginning of each program, a presurvey is administered to assess baseline behavior, attitude, and knowledge regarding distracted driving. After completing the program, teens complete a postsurvey to measure proposed changes in driving behaviors, attitude, and knowledge. The program employs the use of a slide presentation, hospital tour, video, and survivor's testimony to influence teen driving behaviors and increase knowledge. Research has indicated that an increase in the Health Belief Model constructs may enhance engagement in health-promoting behaviors, such as safe driving practices in teens. Based on the postsurvey results, the reduction in projected phone use while driving in this teen population indicates the effectiveness of this hospital-based teen distracted driving program.

We believe that there is significant educational deficit amongst interns regarding up-to-date formal knowledge and skills on healthcare-associated infections (HAIs) which might compromise patient safety. This urgently requires curriculum innovations to ensure their formal training on HAIs prevention and control. Education of interns to improve their knowledge and skills toward HAIs prevention and control. This pilot study was conducted in interns using a multimodal approach consisting of a combination of videos, PowerPoint presentation, and hands-on demonstration to provide applied and practical teaching on prevention and control of HAIs. Pre- and post-test assessment of knowledge, attitude, and skills was carried out by multiple choice questions, 5-point Likert scale, and Objective Structured Practical Examination respectively. Paired t-test. A statistically significant improvement in the overall score rates between pre- and post-test of intern's was seen, suggesting that educational programs have a positive effect. Intern's felt benefitted from interventions focused on HAIs prevention and control and hoped that such sessions are integrated in the regular undergraduate curriculum. A majority of the students felt that their learning style assessment matched well with their own perception of learning preference. Assessment drives learning; hence strengthening the contribution of health-care workers to HAIs prevention programs should include measures that enhance knowledge, improve skills and develop appropriate attitudes, resulting in safety and quality of patient care.

Health care professionals working with the elderly have opportunities through research and clinical practice to shape public policy affecting the older driver. This article describes DriveWise, an interdisciplinary hospital-based driving assessment program developed in response to clinical concerns about the driving safety of individuals with medical conditions. DriveWise clinicians use evidence-based, functional assessments to determine driving competence. In addition, the program was designed to meet the emotional needs of individuals whose driving safety has been called into question. To date, approximately 380 participants have been assessed through DriveWise. The following report details the DriveWise mission, DriveWise team members, and road test results. We continue to refine the assessment process to promote safety and support the dignity and independence of all participants. The DriveWise interdisciplinary approach to practice is a concrete example of how gerontological education across professions can have direct benefits to the older adult.

Background Positive self-esteem, emotional well-being, school achievements and family connectedness are considered protective factors against health-compromising behaviors. This study examined the effect of an interactive, community-based, media literacy and dissonance wellness program, In Favor of Myself, on the self-image, body image, eating attitudes and behavior of young adolescents. A preliminary cohort study was conducted among 972 program participants who did not take part in the controlled trial. Over 75% of participants said they would recommend the program to their friends. Methods A controlled trial was conducted to evaluate program acceptability, efficacy and effectiveness among 259 participants (210 in the intervention group and 49 in the control group), aged 12–14 years, who completed questionnaires during at least two assessment times. Program materials were provided, along with leaders' training, in order to ensure quality program delivery and creation of a wide network of committed program leaders. Results The program significantly reduced drive for thinness and self-worth contingent upon others' approval, the gap between current body figure and ideal figure, and the impact of mood on girls' self-image. Superiority was found among those participating in the intervention group with respect to recognizing media strategies, the influence of media on desire to change, and the influence of appearance on self-confidence and drive for thinness. Conclusions In Favor of Myself shows promising results for strengthening adolescents' ability to cope with the challenges of their life stage. Suggestions for improving In Favor of Myself are presented. PMID:24265681

To assess the knowledge and attitude of medical students towards road safety and to determine their driving behavior and its relation to different related factors. This cross-sectional study involved 480 medical students at Mansoura University, Egypt. A self-administered questionnaire was used to collect student personal data, knowledge about road safety, attitude towards road safety, and driving practices. More than 40% of students experienced an injury in the previous year, mainly as a pedestrian (56%), and 15.2% practiced driving, although only 9.6% had a driving licence. Most of the students had correct road safety knowledge except for awareness that the safe time to read maps is when your vehicle is parked (44%), one should drive in the left lane (29.6%), and one should overtake from the right-hand lane only (25.8%). The majority of the students reported that road traffic injuries can be prevented (89.2%). The mean score of the driving practices of the students ranged from 0.66±1.04 to 2.44±6.28 and rural residents showed significantly higher score regarding errors and lapses. Good road safety knowledge and a favorable, low risk attitude, did not translate into improved road traffic behavior and this highlights the importance of stricter implementation of the existing rules and including road safety in medical education programs.

2005-01-01

Background Seat-belt compliance in trauma patients involved in motor vehicle collisions (MVCs) appears low when compared with compliance of the general public. In this study we wished to define the relative frequency of seat-belt use in injured Canadian drivers and passengers and to determine if there are risk factors particular to seat-belt noncompliance in this cohort. Methods We identified trauma patients who were involved in MVCs over a 24-month period and contacted them 2–4 years after the injury by telephone to administer a standardized survey. Potential determinants of seat-belt noncompliance were compared with the occurrence of an MVC by multiple logistic regression. Results Seat-belt noncompliance in 386 MVC patients was associated with drinking and driving, youth, speeding, male sex, being a passenger, smoking, secondary roads, rural residence, low level of education, overnight driving, having no dependents, licence demerit points, previous collisions, unemployment and short journeys. There was an increase in seat-belt awareness and a decrease in self-rated driving ability after the MVC. Conclusions Factors that indicate poor driving habits (alcohol, speeding, previous MVCs and driving offences) also predict seat-belt noncompliance. Injury prevention programs should selectively target these high-risk drivers to improve seat-belt compliance and limit associated injury and consumption of health care resources. PMID:16248134

The Mars Exploration Rovers (MERs), Spirit and Opportunity, far exceeded their original drive distance expectations and have traveled, at the time of this reporting, a combined 29 kilometers across the surface of Mars. The Rover Sequencing and Visualization Program (RSVP), the current program used to plan drives for MERs, is only a kinematic simulator of rover movement. Therefore, rover response to various terrains and soil types cannot be modeled. Although sandbox experiments attempt to model rover-terrain interaction, these experiments are time-intensive and costly, and they cannot be used within the tactical timeline of rover driving. Imaging techniques and hazard avoidance features on MER help to prevent the rover from traveling over dangerous terrains, but mobility issues have shown that these methods are not always sufficient. ARTEMIS, a dynamic modeling tool for MER, allows planned drives to be simulated before commands are sent to the rover. The deformable soils component of this model allows rover-terrain interactions to be simulated to determine if a particular drive path would take the rover over terrain that would induce hazardous levels of slip or sink. When used in the rover drive planning process, dynamic modeling reduces the likelihood of future mobility issues because high-risk areas could be identified before drive commands are sent to the rover, and drives planned over these areas could be rerouted. The ARTEMIS software consists of several components. These include a preprocessor, Digital Elevation Models (DEMs), Adams rover model, wheel and soil parameter files, MSC Adams GUI (commercial), MSC Adams dynamics solver (commercial), terramechanics subroutines (FORTRAN), a contact detection engine, a soil modification engine, and output DEMs of deformed soil. The preprocessor is used to define the terrain (from a DEM) and define the soil parameters for the terrain file. The Adams rover model is placed in this terrain. Wheel and soil parameter files can be altered in the respective text files. The rover model and terrain are viewed in Adams View, the GUI for ARTEMIS. The Adams dynamics solver calls terramechanics subroutines in FORTRAN containing the Bekker-Wong equations.

To identify the extent and nature of the problem and the main contributing factors to drink driving crashes; determine the current mechanisms in place, particularly in terms of legislation and its enforcement; and identify baseline data and relevant stakeholders. The situational assessment was based on the collection of secondary data from available reports and documents, in-depth interviews with key representatives at a central level, and field surveys in provinces. Vietnam has experienced phenomenal growth in motor vehicles, especially motorcycles, in the last decade (400%). This initially led to an increase in deaths from road crashes, but since 2006 the number has stayed fairly level according to police statistics. However, comparisons with health data suggest that the number of deaths is much higher and there are clearly a number of problems with the relevant data systems. Data on the percentage of drivers exceeding legal limits are not available, but police statistics indicated that drinking alcohol was a contributory factor in 7 percent of motor vehicle crashes. This is likely to be an underestimate, because the police and health services do not have the equipment to measure the blood alcohol concentration (BAC) levels of all drivers in crashes. Motorcycle riders and young people are in the high-risk groups. There are strict BAC limits starting at over zero and severe punishments for drunk drivers involved in serious crashes. However, the police do not have adequate manpower or equipment to conduct regular and frequent roadside checking for drivers who have been drinking. There have also been a number of education programs on road safety including drinking and driving, but these have not included sustained and intensive campaigns targeting the high-risk groups. The National Traffic Safety Committee (NTSC) is responsible for coordinating the relevant agencies but there is still a problem with lack of information sharing between agencies. This study completed a comprehensive situational assessment that examined the problem of drinking and driving and identified some of the weaknesses in the current prevention system. Vietnam currently has 2 international projects on road safety and it is hoped that these together with support from the International Center for Alcohol Policies (ICAP) Global Actions program will provide opportunities for strengthening drinking and drive prevention initiatives by improving the road crash and injury database, building the capacity of the key organizations, strengthening the coordination mechanisms, and implementing and evaluating trial drink-drive interventions.

Diabetes mellitus is a disease which may affect the eligibility to hold a driving license and increase the risk of a road accident. Hypoglycemia while driving is considered to be the most risky situation, with diabetes increasing the mentioned risk for instance due to impaired vision in the case of possible retinopathy. The group of drivers with diabetes being at the greatest risk as to accidents are those with a case history of severe hypoglycemia or hypoglycemia occurred while driving, or possibly of a road accident. Measuring glycaemia before driving and their knowledge how to prevent and treat hypoglycemia - those are the two crucial preventive elements indispensable for insulin treated diabetes patients in order to secure safe road traffic.

Data to Action: Using Environmental Public Health Tracking to Inform Decision Making

Qualters, Judith R; Strosnider, Heather M; Bell, Rosalyn

2017-01-01

Context Public health surveillance includes dissemination of data and information to those who need it to take action to prevent or control disease. The concept of data to action is explicit in the mission of the Centers for Disease Control and Prevention’s (CDC) National Environmental Public Health Tracking Program (Tracking Program). CDC has built a National Environmental Public Health Tracking Network (Tracking Network) to integrate health and environmental data to drive public health action (PHA) to improve communities’ health. Objective To assess the utility of the Tracking Program and its Network in environmental public health practice and policy-making. Design We analyzed information on how Tracking has been used to drive PHAs within funded states and cities (grantees). Two case studies illustrate such use. Setting Analyses included all grantees funded between 2005 and 2013. Participants The number of grantees varied from 17 for 2006–2008 to 24 for 2010–2013. Main Outcome Measures We categorized each PHA reported to determine how grantees became involved, their role, the problems addressed, and the overall action. Results Tracking grantees reported 178 PHAs from 2006–2013. The most common overall action was “provided information in response to concern” (n=42) followed by “improved a public health program, intervention, or response plan” (n=35). Tracking’s role was most often to enhance surveillance (24%) or to analyze data (23%). In 47% of PHAs, the underlying problem was a concern about possible elevated rates of a health outcome, a potential exposure, or a potential association between a hazard and health. PHAs were started by a request for assistance (48%), in response to an emergency (8%), and though routine work by Tracking programs (43%). Conclusion Our review shows that the data, expertise, technical infrastructure, and other resources of the Tracking Program and its Network are driving state and local PHAs. PMID:25621441

Driving habits and risk exposure in older drivers: lessons learned from the implementation of a self-regulation curriculum.

This article describes the development and pilot testing of Seniors on the MOVE (Mature Operators Vehicular Education), a safe driving education program for older adults. The study aims are to describe driving experiences and habits of a community sample of older drivers and to determine whether the program reduces their driving risk exposures. A 2-group randomized design was used. Fifty-eight participants with an average age of 70 were randomly assigned to the MOVE program or a no treatment control group. MOVE is a 4-session program designed to help older drivers better understand and utilize self-regulation skills for safer driving. Baseline and 4-week follow-up questionnaires were completed by both groups, after which the control group received the MOVE program. In the total sample, 14 percent reported having ever been in a traffic crash where someone was injured, and 10 percent reported having received a traffic citation in the past 6 months. Almost one half of the sample (47%) reported thinking about reducing the amount of driving done at night. Nearly one third were thinking about reducing the amount of driving done in unfamiliar places (32%) and the number of miles driven each week (30%). Participants reported most frequently driving between 2 to 10 miles from home, on local roadways, and between 9:00 am and 4:00 pm. Based on responses to items that measured such driving habits, a risk exposure score was created by combining driving exposure variables. Participants were categorized into lower and higher driving risk exposure groups at baseline and follow-up. There were no statistical differences in changes in higher or lower risk driving exposure variables when comparing the 2 groups. Although the impact of this program on reported driving behaviors yielded null results, descriptions of older drivers' habits and plans are informative. Because many participants were thinking about making changes to their driving habits, and many already had, the need for more effective self-regulation driving safety programs to help with this process is clear.

Drowsy driving is a serious public health concern which is often difficult for individual drivers to identify. While it is important for drivers to understand the causes of drowsy driving, there is still insufficient scientific knowledge and public education to prevent drowsy driving. As a result, the AASM is calling upon institutions and policy makers to increase public awareness and improve education on the issue, so our society can better recognize and prevent drowsy driving. The AASM has adopted a position statement to educate both healthcare providers and the general public about drowsy driving risks and countermeasures.

Links between preclinical AD and driving difficulty onset would support the use of driving performance as an outcome in primary and secondary prevention trials among older adults (OAs). We examined whether AD biomarkers predicted the onset of driving difficulties among OAs. 104 OAs (65+ years) with normal cognition took part in biomarker measurements, a road test, clinical and psychometric batteries and self-reported their driving habits. Higher values of CSF tau/Aβ 42 and ptau 181 /Aβ 42 ratios, but not uptake on PIB amyloid imaging (p=.12), predicted time to a rating of Marginal or Fail on the driving test using Cox proportional hazards models. Hazards ratios (95% confidence interval) were 5.75 (1.70-19.53), p=.005 for CSF tau/Aβ 42 ; 6.19 (1.75-21.88) and p=.005 for CSF ptau 181 /Aβ 42 . Preclinical AD predicted time to receiving a Marginal or Fail rating on an on-road driving test. Driving performance shows promise as a functional outcome in AD prevention trials.

Young people and snowmobiling in northern Norway: accidents, injury prevention and safety strategies.

Snowmobiling among young people in Scandinavia frequently leads to accidents and injuries. Systematic studies of accidents exist, but few studies have addressed young drivers' experiences. The aim of this article is to reveal how young people experience and interpret accidents, and to outline a prevention strategy. Thirty-one girls and 50 boys aged 16-23 years from secondary schools in Northern Norway and on Svalbard, a Norwegian archipelago in the Arctic Ocean, participated in 17 focus groups segregated by gender. A content analysis identified themes addressing the research questions. Participants described risk as being inherent to snowmobiling, and claimed that accidents followed from poor risk assessment, careless driving or mishaps. Evaluation of accidents and recommendations for preventive measures varied. Girls acknowledged the risks and wanted knowledge about outdoor life, navigation and external risks. Boys underestimated or downplayed the risks, and wanted knowledge about safety precautions while freeriding. Both genders were aware of how and why accidents occurred, and took precautions. Boys tended to challenge norms in ways that contradict the promotion of safe driving behaviour. Stories of internal justice regarding driving under the influence of alcohol occurred. Adolescents are aware of how accidents occur and how to avoid them. Injury prevention strategies should include a general population strategy and a high-risk strategy targeted at extreme risk-seekers. Drivers, snowmobilers' organisations and the community should share local knowledge in an effort to define problem areas, set priorities and develop and implement preventive measures. Risk prevention should include preparation of safe tracks and focus on safety equipment and safe driving behaviour, but should also pay increased attention to the potential of strengthening normative regulation within peer groups regarding driving behaviour and mutual responsibility for preventing accidents.

Adolescent drivers: a developmental perspective on risk, proficiency, and safety.

2008-09-01

Despite considerable improvement in the rates of crashes, injuries, and fatalities among adolescent drivers, attributable in part to effective interventions such as graduated driver licensing, these rates and their associated health risks remain unacceptably high. To understand the sources of risky driving among teens, as well as to identify potential avenues for further advances in prevention, this article presents a review of the relevant features of contemporary research on adolescent development. Current research offers significant advances in the understanding of the sources of safe driving, proficient driving, and risky driving among adolescents. This multifaceted perspective--as opposed to simple categorization of good versus bad driving--provides new opportunities for using insights on adolescent development to enhance prevention. Drawing on recent work on adolescent physical, neural, and cognitive development, we argue for approaches to prevention that recognize both the strengths and the limitations of adolescent drivers, with particular attention to the acquisition of expertise, regulatory competence, and self-regulation in the context of perceived risk. This understanding of adolescent development spotlights the provision of appropriate and effective scaffolding, utilizing the contexts of importance to adolescents--parents, peers, and the broader culture of driving--to support safe driving and to manage the inherent risks in learning to do so.

This study assessed the impact of an education program on knowledge of sleepiness and driving behaviour in young adult drivers and their performance and behaviour during simulated night driving. Thirty-four participants (18-26 years old) were randomized to receive either a four-week education program about sleep and driving or a control condition. A series of questionnaires were administered to assess knowledge of factors affecting sleep and driving before and after the four-week education program. Participants also completed a two hour driving simulator task at 1am after 17 h of extended wakefulness to assess the impact on driving behaviour. There was an increase in circadian rhythm knowledge in the intervention group following the education program. Self-reported risky behaviour increased in the control group with no changes in other aspects of sleep knowledge. There were no significant differences in proportion of intervention and control participants who had microsleeps (p ≤ .096), stopped driving due to sleepiness (p = .107), recorded objective episodes of drowsiness (p = .455), and crashed (p = .761), although there was a trend towards more control participants having microsleeps and stopping driving. Those in the intervention group reported higher subjective sleepiness at the end of the drive [M = 6.25, SD = 3.83, t(31) = 2.15, p = .05] and were more likely to indicate that they would stop driving [M = 3.08, SD = 1.16, t(31) = 2.24, p = .04]. The education program improved some aspects of driver knowledge about sleep and safety. The results also suggested that the education program lead to an increased awareness of sleepiness. Education about sleep and driving could reduce the risk of drowsy driving and associated road trauma in young drivers, but requires evaluation in a broader sample with assessment of real world driving outcomes.

Little is known about the nature and scope of aggressive driving in developing countries. The objective of this study is to specifically examine the sociodemographic factors associated with aggressive driving behavior among 3-wheeler taxi drivers in Sri Lanka. Convenience samples of 3-wheeler taxi drivers from Rathnapura, Ahaliyagoda, Sri Lanka were surveyed from June to August 2006. Analyses included bivariate and multivariate logistic regression. Drivers with less than high school education were 3.5 times more likely to drive aggressively (odds ratio [OR] = 3.46; 95% confidence interval [CI] = 1.08, 11.1). Single drivers were 9 times more likely to run red lights (OR = 8.74; 95% CI = 2.18, 35.0), and being single was a major risk factor for drunk driving (OR = 4.80; 95% CI = 1.23, 18.7). Furthermore, high school completers were 4 times more likely to bribe a policeman (OR = 4.27; 95% CI = 1.23, 14.9) when caught violating the road rules. Aggressive driving and risk-taking behavior are amenable to policy initiatives, and preventive programs targeted at key groups could be used to improve road safety in Sri Lanka. This study demonstrates that aggressive driving behavior is associated with sociodemographic factors, including the level of education, marital status, and other socioeconomic factors. Hence, economic factors should be addressed to find solutions to traffic-related issues. It will be the government's and policy makers' responsibility to try and understand the economic factors behind risky road behavior and bribe-taking behavior prior to legislating or enforcing new laws.

Alcohol and marijuana use patterns associated with unsafe driving among U.S. high school seniors: high use frequency, concurrent use, and simultaneous use.

This article examines noncausal associations between high school seniors' alcohol and marijuana use status and rates of self-reported unsafe driving in the past 12 months. Analyses used data from 72,053 students collected through annual surveys of nationally representative cross-sectional samples of U.S. 12th-grade students from 1976 to 2011. Two aspects of past-12-month alcohol and marijuana use were examined: (a) use frequency and (b) status as a nonuser, single substance user, concurrent user, or simultaneous user. Measures of past-12-month unsafe driving included any tickets/warnings or accidents, as well as tickets/warnings or accidents following alcohol or marijuana use. Analyses explored whether an individual's substance use frequency and simultaneous use status had differential associations with their rate of unsafe driving. Higher substance use frequency (primarily alcohol use frequency) was significantly and positively associated with unsafe driving. The rate of engaging in any unsafe driving was also significantly and positively associated with simultaneous use status, with the highest rate associated with simultaneous use, followed by concurrent use, followed by use of alcohol alone. Individuals who reported simultaneous use most or every time they used marijuana had the highest likelihood of reporting unsafe driving following either alcohol or marijuana use. This article expands the knowledge on individual risk factors associated with unsafe driving among teens. Efforts to educate U.S. high school students (especially substance users), parents, and individuals involved in prevention programming and driver's education about the increased risks associated with various forms of drug use status may be useful.

The Predictive Influence of Youth Assets on Drinking and Driving Behaviors in Adolescence and Young Adulthood.

Drinking and driving among adolescents and young adults remains a significant public health burden. Etiological research is needed to inform the development and selection of preventive interventions that might reduce alcohol-involved crashes and their tragic consequences. Youth assets-that is, skills, competencies, relationships, and opportunities-can help youth overcome challenges, successfully transition into adulthood, and reduce problem behavior. We examined the predictive influence of individual, relationship, and community assets on drinking and driving (DD) and riding with a drinking driver (RDD). We assessed prospective relationships through analysis of data from the Youth Assets Study, a community-based longitudinal study of socio-demographically diverse youth. Results from calculation of marginal models using a Generalized Estimating Equation approach revealed that parent and peer relationship and school connectedness assets reduced the likelihood of both drinking and driving and riding with a drinking driver approximately 1 year later. The most important and consistent asset that influenced DD and RDD over time was parental monitoring, highlighting the role of parental influence extending beyond the immediate teen driving context into young adulthood. Parenting-focused interventions could influence factors that place youth at risk for injury from DD to RDD, complementing other evidence-based strategies such as school-based instructional programs and zero tolerance Blood Alcohol Concentration laws for young and inexperienced drivers.

In this paper, we describe a new framework to combine experts’ judgments for the prevention of driving risks in a cabin truck. In addition, the methodology shows how to choose among the experts the one whose predictions fit best the environmental conditions. The methodology is applied over data sets obtained from a high immersive cabin truck simulator in natural driving conditions. A nonparametric model, based in Nearest Neighbors combined with Restricted Least Squared methods is developed. Three experts were asked to evaluate the driving risk using a Visual Analog Scale (VAS), in order to measure the driving risk in a truck simulator where the vehicle dynamics factors were stored. Numerical results show that the methodology is suitable for embedding in real time systems.

Young drivers represent a disproportionate number of the individuals involved in alcohol-impaired driving. Although there is a known association between drinking and alcohol-impaired driving in young drivers, the link between early onset drinking and early onset alcohol-impaired driving has not been explored. The present study aimed to assess this link along with potentially confounding factors. The assessment used a proportional hazards model with data collected from the Buffalo Longitudinal Study of Young Men, a population-based sample of 625 males at aged 16-19. Controlling for the effects of potentially relevant confounds, the early onset of drinking was the most influential factor in predicting the early onset of alcohol-impaired driving. Race and the early onset of other forms of delinquency also played a significant role in the early onset of alcohol-impaired driving. Preventing an early start of drinking among adolescents may be the most critical factor to address in preventing an early start of alcohol-impaired driving.

Electromagnetic brake/clutch device

Vranish, John M. (Inventor)

1994-01-01

An electromagnetic brake/clutch device includes a drive shaft supported by at least one bearing for transmitting torque, a housing, affixed to prevent its rotation, surrounding the drive shaft, and an electromagnetically activated device within the housing to selectively prevent and allow rotation of the drive shaft. The electromagnetically activated device includes a plurality of cammed rollers to prevent counter-clockwise rotation of the drive shaft. The drive shaft includes a circumferential disk and the housing includes a reaction ring for engagement with the plurality of cammed rollers. The plurality of cammed rollers are released from engagement with the circumferential disk and the reaction ring by a plurality of tripping mechanisms within the housing. The tripping action uses the locking force to act as a release force merely by changing the boundary conditions of the roller interface angles. The tripping mechanisms include trippers for disengaging the plurality of cammed rollers and an anvil shaped portion for providing lateral movement of the trippers. The plurality of cammed rollers is preloaded to engagement with the circumferential disk and reaction ring by a spring, and is located with respect to an adjacent tripping mechanism with another spring.

Determining Acceptable Limits of Fast-Electron Preheat in Polar-Drive-Ignition Designs

2014-10-01

In direct-drive-ignition designs, preheat by fast electrons created by the two-plasmon-decay instability at the quarter-critical density surface can increase the adiabat in the fuel layer and prevent ignition. Since eliminating the preheat entirely is not possible, it is necessary to understand the levels of preheat our targets can withstand before ignition is precluded. The current polar-drive point design is used as the basis for examining the effects of increasing the levels of fast electrons using the one-dimensional, radiation-hydrodynamics code LILAC. Once ignition failure is obtained, the design is then reoptimized using Telios, a downhill simplex method program, to recover ignition. This cycle is repeated until the design can no longer be reoptimized to produce ignition. Mappings of these final results provide insight into ignition failure caused by preheat and what specific target parameters serve to best stave off the effects of the preheat.

Chronic diseases are currently recognized as one of the leading causes of mortality and morbidity worldwide. On top of this, these diseases represent a major burden for the healthcare systems in terms of costs and resources, which is driving them to define and adopt novel programs for prevention and chronic disease management. Still, many aspects of the processes of care and follow up of these patients remain unsolved and there is yet uncertainty on how technology can provide an added value to the current processes of care. This paper addresses the importance of the adoption of strategies for the anticipation to acute events within the disease management programs and suggests a holistic approach to embrace the healthcare organizations in the design development and implementation of the new personal health systems.

Background: Rapid assessment and management of transient ischemic attacks and nondisabling strokes by specialized stroke prevention services reduces the risk of recurrent stroke and improves outcomes. In Canada, with its vast geography and with 16.8% of the population living in rural areas, access to these services is challenging, and considerable variation in access to care exists. The purpose of this multiphase study was to identify sites across Canada providing stroke prevention services, evaluate resource capacity and determine geographic access for Canadians. Methods: We developed a Stroke Prevention Services Resource Inventory that contained 22 questions on the organization and delivery of stroke prevention services and quality monitoring. The inventory ran from November 2015 to January 2016 and was administered online. We conducted a geospatial analysis to estimate access by drive times. Considerations were made for hours of operation and access within and across provincial borders. Results: A total of 123 stroke prevention sites were identified, of which 119 (96.7%) completed the inventory. Most (95) are designated stroke prevention or rapid assessment clinics. Of the 119 sites, 68 operate full time, and 39 operate less than 2.5 days per week. A total of 87.3% of the Canadian population has access to a stroke prevention service within a 1-hour drive; however, only 69.2% has access to a service that operates 5-7 days a week. Allowing provincial border crossing improves access (< 6-h drive) for those who are beyond a 6-hour drive within their home province (3.4%). Interpretation: Most Canadians have reasonable geographic access to stroke prevention services. Allowing patients to cross borders improves the existing access for many, particularly some remote communities along the Ontario-Quebec and British Columbia-Alberta borders. PMID:29472251

Cash transfer programs seek to alter structural determinants of HIV risk such as poverty and gender inequality. We sought to explore the feasibility and potential effectiveness of a cash transfer intervention for young women as part of combination HIV prevention in Iringa, Tanzania. Qualitative, in-depth interviews were conducted with 116 stakeholders and residents from the region, including key informants, service delivery users, and members of key populations. Most respondents felt a cash transfer program would assist young women in Iringa to have more control over sexual decision-making and reduce poverty-driven transactional sex. Respondents were divided on who should receive funds: young women themselves, their parents/guardians, or community leaders. Cash amounts and suggested target groups varied, and several respondents suggested providing microcredit or small business capital instead of cash. Potential concerns included jealousy, dependency, and corruption. However, most respondents felt that some intervention was needed to address underlying poverty driving some sexual risk behavior. A cash transfer program could fill this role, ultimately reducing HIV, sexually transmitted infections, and unintended pregnancies. As increased attention is given to economic and structural interventions for HIV prevention, local input and knowledge should be considered in a program design.

Patients with an implantable cardioverter defibrillator (ICD) have an ongoing risk of sudden incapacitation that might cause harm to others while driving a car. Driving restrictions vary across different countries in Europe. The most recent recommendations for driving of ICD patients in Europe were published in 1997 and focused mainly on patients implanted for secondary prevention. In recent years there has been a vast increase in the number of patients with an ICD and in the percentage of patients implanted for primary prevention. The EHRA task force on ICD and driving was formed to reassess the risk of driving for ICD patients based on the literature available. The recommendations are summarized in the following table and are further explained in the document, (Table see text). Driving restrictions are perceived as difficult for patients and their families, and have an immediate consequence for their lifestyle. To increase the adherence to the driving restrictions, adequate discharge of education and follow-up of patients and family are pivotal. The task force members hope this document may serve as an instrument for European and national regulatory authorities to formulate uniform driving regulations. Copyright (c) 2010 Elsevier B.V.

An increasing number of older adults rely on the automobile for transportation. Educational approaches based on the specific needs of older drivers may help to optimize safe driving. We examined if the combination of an in-class education program with on-road education would lead to improvements in older drivers' knowledge of safe driving practices and on-road driving evaluations. We used a multisite, randomized controlled trial approach. Participants in the intervention group received the in-class and on-road education; those in the control group waited and were offered the education afterwards. We measured knowledge of safe driving practices before and after the in-class component of the program and on-road driving skills before and after the whole program. Participants' knowledge improved from 61% of correct answers before the in-class education component to 81% after (p < .001). The on-road evaluation results suggested improvements on some aspects of safe driving (e.g., moving in roadway, p < .05) but not on others. The results of this study demonstrate that education programs focused on the needs of older drivers may help improve their knowledge of safe driving practices and actual driving performance. Further research is required to determine if these changes will affect other variables such as driver confidence and crash rates.

Beck, Kenneth H; Lee, Clark J; Weiner, Talia

2018-02-01

This qualitative investigation sought to identify the motivational factors that contribute to drowsy driving in college students and to discover important messaging strategies that may help prevent or reduce this behavior in this population. Four focus groups of college students. A large university in the Washington, DC, metropolitan area during the Fall 2016 term. Twenty-six undergraduate students between the ages of 18 and 25 years. Notes and transcripts from the focus group sessions were analyzed to identify recurring themes regarding attitudes, motivations, experiences, influences, and potential preventive messaging strategies related to drowsy driving. Although most participants had heard of drowsy driving and were concerned about it, they did not associate it with legal risks and were more concerned about alcohol-impaired and distracted driving as crash risks. Participants viewed drowsy driving as a normal and unavoidable part of their lives over which they had little control. For potential anti-drowsy driving messaging strategies, participants preferred messages delivered via audiovisual or social media that featured graphic and emotional portrayals of crashes and their consequences. Participants also voiced strong support for preventive messaging strategies equating various degrees of sleep deprivation to known impairing levels of alcohol, as well as messages providing cues to action to actual drowsy drivers on roadways. Increased enforcement, education, and public messaging campaigns are needed to increase knowledge and influence attitudes and opinions among young drivers about the dangers and social unacceptability of drowsy driving.

Indirect drive ignition at the National Ignition Facility

Meezan, N. B.; Edwards, M. J.; Hurricane, O. A.

This article reviews scientific results from the pursuit of indirect drive ignition on the National Ignition Facility (NIF) and describes the program's forward looking research directions. In indirect drive on the NIF, laser beams heat an x-ray enclosure called a hohlraum that surrounds a spherical pellet. X-ray radiation ablates the surface of the pellet, imploding a thin shell of deuterium/tritium (DT) that must accelerate to high velocity (v > 350 km s -1) and compress by a factor of several thousand. Since 2009, substantial progress has been made in understanding the major challenges to ignition: Rayleigh Taylor (RT) instability seededmore » by target imperfections; and low-mode asymmetries in the hohlraum x-ray drive, exacerbated by laser-plasma instabilities (LPI). Requirements on velocity, symmetry, and compression have been demonstrated separately on the NIF but have not been achieved simultaneously. We now know that the RT instability, seeded mainly by the capsule support tent, severely degraded DT implosions from 2009–2012. Experiments using a 'high-foot' drive with demonstrated lower RT growth improved the thermonuclear yield by a factor of 10, resulting in yield amplification due to alpha particle heating by more than a factor of 2. However, large time dependent drive asymmetry in the LPI-dominated hohlraums remains unchanged, preventing further improvements. High fidelity 3D hydrodynamic calculations explain these results. In conclusion, future research efforts focus on improved capsule mounting techniques and on hohlraums with little LPI and controllable symmetry. In parallel, we are pursuing improvements to the basic physics models used in the design codes through focused physics experiments.« less

Marcotte, Thomas D.; Bekman, Nicole M.; Meyer, Rachel A.; Brown, Sandra A.

2013-01-01

Background Binge drinking is common among adolescents. Alcohol use, and binge-drinking in particular, has been associated with neurocognitive deficits as well as risk-taking behaviors, which may contribute to negative driving outcomes among adolescents even while sober. Objectives To examine differences in self-reported driving behaviors between adolescent binge-drinkers and a matched sample of controls, including (a) compliance with graduated licensing laws, (b) high risk driving behaviors, and (c) driving outcomes (crashes, traffic tickets). Methods The present study examined driving behaviors and outcomes in adolescent recent binge drinkers (n=21) and demographically and driving history matched controls (n=17), ages 16-18. Results Binge drinkers more frequently violated graduated licensing laws (e.g., driving late at night), and engaged in more “high risk” driving behaviors, such as speeding and using a cell-phone while driving. Binge drinkers had more traffic tickets, crashes and “near crashes” than the control group. In a multivariate analysis, binge drinker status and speeding were the most robust predictors of a crash. Conclusion Binge drinking teens consistently engage in more dangerous driving behaviors and experience more frequent crashes and traffic tickets. They are also less compliant with preventative restrictions placed on youth while they are learning critical safe driving skills. Scientific Significance These findings highlight a need to examine the contribution of underlying traits (such as sensation seeking) and binge-related cognitive changes to these high-risk driving behaviors, which may assist researchers in establishing alternative prevention and policy efforts targeting this population.

Reducing Sexual Assault on Campus: Lessons From the Movement to Prevent Drunk Driving

PubMed Central

2016-01-01

I examined similarities and differences between the movement to prevent drunk driving of the 1980s, and current efforts to prevent and address campus sexual assault. As college and university administrators design policies and initiatives to reduce campus sexual assault in response to new federal legislation and regulation, they can apply lessons from successful public health initiatives to reduce drunk driving initiated more than 3 decades ago. I illustrate how interventions at the 5 levels of the social–ecological model, and messages that address entrenched cultural attitudes condoning sexual assault and blaming its victims can be used to combat campus sexual assault as a crime and a public health problem. I also show how efforts to promote community engagement can change behavioral norms and reduce offenses. PMID:26985614

THE LINK BETWEEN EARLY ONSET DRINKING AND EARLY ONSET ALCOHOL-IMPAIRED DRIVING IN YOUNG MALES

2014-01-01

Background Young drivers represent a disproportionate number of the individuals involved in alcohol-impaired driving. Although there is a known association between drinking and alcohol-impaired driving in young drivers, the link between early onset drinking and early onset alcohol-impaired driving has not been explored. Objectives The present study aimed to assess this link along with potentially confounding factors. Methods The assessment used a proportional hazards model with data collected from the Buffalo Longitudinal Study of Young Men, a population based sample of 625 males at ages of 16–19 years old. Results Controlling for the effects of potentially relevant confounds, the early onset of drinking was the most influential factor in predicting the early onset of alcohol-impaired driving. Race and the early onset of other forms of delinquency also played a significant role in the early onset of alcohol-impaired driving. Conclusion Preventing an early start of drinking among adolescents may be the most critical factor to address in preventing an early start of alcohol-impaired driving. PMID:24766089

In an effort to find a more proactive solution to the problem of drunk driving, a midwestern city has implemented a Driving Under the Influence or Driving While Impaired (DUI/DWI) Court program, a derivative of the popular drug courts. Eligible participants are those who have had two or more drunk-driving offenses but who have not been convicted of a violent offense. Participants volunteer for a 36-week program in exchange for a suspension of their prison sentence. Program elements include drug/alcohol monitoring, support groups, counseling, and extensive supervision. Using a phenomenological approach, this article describes the challenges faced by 20 participants, how they navigated the program requirements, their key realizations about their conditions, and their views on the viability and effectiveness of the program. The article uses qualitative interviews of participants and stakeholders collected for a process evaluation of the DUI program, and official records collected for programming purposes. Findings from this research can be used broadly for programming purposes and can be used by other court jurisdictions that are developing similar programs.

Stemming from the need to prevent, detect and suppress on-board spacecraft fires, the NASA microgravity combustion research program has grown to include fundamental research. From early experiment, we have known that flames behave differently in microgravity, and this environment would provide an ideal laboratory for refining many of the long held principals of combustion science. A microgravity environment can provide direct observation of phenomena that cannot be observed on Earth. Through the years, from precursor work performed in drop towers leading to experiments on the International Space Station (ISS), discoveries have been made about the nature of combustion in low gravity environments. These discoveries have uncovered new phenomena and shed a light on many of the fundamental phenomena that drive combustion processes. This paper discusses the NASA microgravity combustion research program taking place in the ISS Combustion Integrated Rack, its various current and planned experiments, and the early results from the Flame Extinguishment (FLEX) Experiment.

Crash rates among teenagers are highly elevated during the first months of licensure. Parent-imposed driving restrictions on initial driving privileges can reduce exposure to high-risk driving conditions, thus reducing crash risk while teens' driving proficiency develops. This report describes the effect of the Checkpoints Program on driving limits and outcomes. Connecticut teens who obtained a learners permit over a 9-month period were recruited, providing a final sample of 3743 who obtained driver licenses. Families were randomized to the intervention or comparison condition. Intervention families received by mail a series of persuasive communications related to high-risk teen driving and a parent-teen driving agreement, while comparison families received on the same schedule general information on driving and vehicle maintenance. Relative to the comparison group, teens and parents in the Checkpoints Program reported significantly greater limits on high-risk teen driving conditions at licensure, 3-, and 6-months post-licensure; and intervention teens reported significantly less risky driving at each reporting period. By the 12-month follow up teens in the intervention group were significantly less likely than those in the comparison group to have had a traffic violation. However, no treatment group effect was found for crashes. This is the first study to report significant effects on teen driving behavior and performance of education designed to increase parental-imposed teen driving limits.

Evaluating the effectiveness of a post-license education program for young novice drivers in Belgium.

2014-05-01

The disproportionately large number of traffic accidents of young novice drivers highlights the need for an effective driver education program. The Goals for Driving Education (GDE) matrix shows that driver education must target both lower and higher levels of driver competences. Research has indicated that current education programs do not emphasize enough the higher levels, for example awareness and insight. This has raised the importance of insight programs. On the Road (OtR), a Flemish post-license driver education program, is such an insight program that aims to target these higher levels. The program focus is on risky driving behavior like speeding and drink driving. In addition, the program addresses risk detection and risk-related knowledge. The goal of the study was to do an effect evaluation of this insight program at immediate post-test and 2 months follow-up. In addition, the study aimed to generalize the results of this program to comparable programs in order to make usable policy recommendations. A questionnaire based on the Theory of Planned Behavior (TPB) was used in order to measure participants' safety consciousness of speeding and drink driving. Moreover, we focused on risk detection and risk-related knowledge. Participants (N=366) were randomly assigned to a baseline-follow-up group or a post-test-follow-up group. Regarding speeding and driving, we found OtR to have little effect on the TPB variables. Regarding risk detection, we found no significant effect, even though participants clearly needed substantial improvement when stepping into the program. Regarding risk-related knowledge, the program did result in a significant improvement at post-test and follow-up. It is concluded that the current program format is a good starting point, but that it requires further attention to enhance high level driving skills. Program developers are encouraged to work in a more evidence-based manner when they select target variables and methods to influence these variables. Copyright © 2014 Elsevier Ltd.

Mitochondrial ROS Drive Sudden Cardiac Death and Chronic Proteome Remodeling in Heart Failure.

PubMed

Dey, Swati; DeMazumder, Deeptankar; Sidor, Agnieszka; Foster, D B; O'Rourke, Brian

2018-06-13

Rationale: Despite increasing prevalence and incidence of heart failure (HF), therapeutic options remain limited. In early stages of HF, sudden cardiac death (SCD) from ventricular arrhythmias claims many lives. Reactive oxygen species (ROS) have been implicated in both arrhythmias and contractile dysfunction. However, little is known about how ROS in specific subcellular compartments contribute to HF or SCD pathophysiology. The role of ROS in chronic proteome remodeling has not been explored. Objective: We will test the hypothesis that elevated mitochondrial ROS (mROS) is a principal source of oxidative stress in HF and in vivo reduction of mROS mitigates SCD. Methods and Results: Using a unique guinea pig model of non-ischemic HF that recapitulates important features of human HF, including prolonged QT interval and high incidence of spontaneous arrhythmic SCD. Compartment-specific ROS sensors revealed increased mROS in resting and contracting left ventricular (LV) myocytes in failing hearts. Importantly, mitochondrially-targeted antioxidant (MitoTEMPO) normalized global cellular ROS. Further, in vivo MitoTEMPO treatment of HF animals prevented and reversed HF; eliminated SCD by decreasing dispersion of repolarization and ventricular arrhythmias; suppressed chronic HF-induced remodeling of the expression proteome; and prevented specific phosphoproteome alterations. Pathway analysis of mROS-sensitive networks indicated that increased mROS in HF disrupts the normal coupling between cytosolic signals and nuclear gene programs driving mitochondrial function, antioxidant enzymes, Ca2+ handling and action potential repolarization, suggesting new targets for therapeutic intervention. Conclusions: mROS drive both acute emergent events, such as electrical instability responsibly for SCD, and those that mediate chronic HF remodeling, characterized by suppression or altered phosphorylation of metabolic, antioxidant and ion transport protein networks. In vivo reduction of mROS prevents and reverses electrical instability, SCD and HF. Our findings support the feasibility of targeting the mitochondria as a potential new therapy for HF and SCD while identifying new mROS-sensitive protein modifications.

After the launch of the US President's Emergency Plan for AIDS Relief in 2003, it became evident that inadequate laboratory systems and services would severely limit the scale-up of human immunodeficiency virus infection prevention, care, and treatment programs. Thus, the Office of the US Global AIDS Coordinator, Centers for Disease Control and Prevention, and Becton, Dickinson and Company developed a public-private partnership (PPP). Between October 2007 and July 2012, the PPP combined the competencies of the public and private sectors to boost sustainable laboratory systems and develop workforce skills in 4 African countries. Key accomplishments of the initiative include measurable and scalable outcomes to strengthen national capacities to build technical skills, develop sample referral networks, map disease prevalence, support evidence-based health programming, and drive continuous quality improvement in laboratories. This report details lessons learned from our experience and a series of recommendations on how to achieve successful PPPs. © The Author 2016.

Ojajärvi, J

1996-01-01

To determine whether a specially designed antisuction device can prevent the bacterial contamination of the drive air lines of the dental turbine that is caused by suction when the turbine is stopped. A dental unit with and without the antisuction device and three different types of sterilized handpieces were used in the tests. Each turbine was operated in air, then submerged into a bacterial suspension of E. coli and enterococci for 3 seconds, removed, and stopped. This procedure was repeated 10 times. Possible bacterial contamination of the drive air lines was examined by submersing the head of a sterilized handpiece with the turbine running into a nutrient broth for 30 seconds. The broth was incubated at 35 degrees C up to 2 days. After use of the conventional dental unit, bacterial growth of drive air lines was found in 10 of 150 broth samples. After the installation of the antisuction device no bacterial growth was found in any of the 138 samples. The difference in the contamination frequencies is statistically significant (p = 0.011, Fisher's two-sided exact test). The drive air lines of the turbine in the dental unit may become contaminated despite the sterilization of handpieces. The antisuction device installed into the dental unit was found to prevent the contamination. With the exception of possibly immunocompromised patients, the transmission of microbes by exhaust air may be too small to cause infections. However, transmission of oral material between patients should be prevented in dental practice.

Kim, Jungah; Shon, Changwoo

2018-01-01

The Medical Aid program is government’s medical benefit program to secure the minimum livelihood and medical services for low-income Korean households. In Seoul, the number of Medical Aid beneficiaries has grown, driving an increases in the length of stay (LOS) and healthcare cost. Until now, studies have focused on quantity indicators, such as LOS, but only a few studies have been conducted on the service quality. We investigated both LOS and the preventable hospitalization (PH) rate as proxy indicators for the quantity and quality of services provided to Medical Aid beneficiaries in Seoul. To understand the program’s impact, we extracted appropriate data of Medical Aid beneficiaries and data of the lower 20% of National Health Insurance (NHI) enrollees, performed Propensity Score Matching (PSM), and controlled the variables related to disease severity. The differences between Medical Aid beneficiaries and NHI enrollees were estimated using multilevel analysis. The LOS of Medical Aid beneficiaries was longer, and the preventable hospitalization (PH) rate was higher than that of NHI enrollees. It implies that these beneficiaries did not receive timely and adequate healthcare services, despite their high rate of service utilization. Thus, indicators such as patient’s visits and screening related to PHs should be included in management policies to improve primary care. PMID:29673147

DNA methylation and histone modifications determine renal programming and the development and progression of renal disease. The identification of the way in which the renal cell epigenome is altered by environmental modifiers driving the onset and progression of renal diseases has extended our understanding of the pathophysiology of kidney disease progression. In this review, we focus on current knowledge concerning the implications of epigenetic modifications during renal disease from early development to chronic kidney disease progression including renal fibrosis, diabetic nephropathy and the translational potential of identifying new biomarkers and treatments for the prevention and therapy of chronic kidney disease and end-stage kidney disease.

Gender is crucial issue in slowing the spread of HIV.

PubMed

During the UN General Assembly Special Session, Peter Piot, executive director of the Joint UN Programme on HIV/AIDS (UNAIDS), spoke about gender inequality and its role in the AIDS epidemic. According to Piot, gender inequality is a fundamental driving force of the AIDS epidemic and therefore must be addressed centrally in responding to the epidemic. Biological and social factors make women and girls more vulnerable to AIDS than men; hence, equity in health, education, environment, and economy are essential if women are to act to protect themselves against HIV and AIDS. This concept is supported by the World AIDS Campaign, in which harmful concepts of masculinity are challenged and the view is affirmed that changing long-held beliefs and attitudes must be part of preventive efforts. In addition, Piot recommends that AIDS prevention programs should give greater emphasis to the role of men in health care and create better ways for men and women to communicate and take responsibility for issues of concern in preventing HIV/AIDS.

Driver distraction: a perennial but preventable public health threat to adolescents.

PubMed

Bingham, C Raymond

2014-05-01

Although public health efforts have made some progress in reducing risk of adolescent motor vehicle crashes over the last three decades, new technologies and evolving behavior patterns have focused attention on the risk of distracted driving. For many of the same reasons that alcohol-impaired driving represents a distinct risk for adolescents, distracted driving has an elevated impact on this age group. Similarly, many of the strategies used to reduce alcohol-impaired driving among adolescents might be applied to driver distraction, including adults serving as role models with high standards of behavior. The unique challenge posed by the proliferation of new technological distractions may accelerate this risk behavior and may lend itself to innovative prevention efforts.

Let them experience a ride under the influence of alcohol; a successful intervention program?

2011-05-01

A considerable amount of all traffic accidents can be attributed to driving under the influence of alcohol. In particular the group of drivers aged 18-24 years is involved in many serious traffic accidents where alcohol turns out to be a major factor. In fact this age group shows about three times as many alcohol related traffic fatalities as all other categories of road users. The intervention program "Alcohol-free on the road" (Dutch: "Alcoholvrij op weg") aims to enhance young people's awareness of the effects of alcohol by letting them personally experience the effect of alcohol on their driving abilities. To this end, young drivers were invited to a closed circuit and allowed to drive first sober and then intoxicated, guided and guarded by driving instructors. Based on several other studies it was thought that a realistic experience of the effects of alcohol on driving abilities may contribute to a better understanding of the impact of alcohol and may stimulate attitudes that are needed to support the conscious decision not to drive while intoxicated. After more than ten years of running and data collection, 1200 young drivers have participated in the intervention program. In a quasi-experimental study with a non-equivalent group design, the program is evaluated in order to assess its effectiveness both with respect to the attitudes of the participants and the actual relevant behaviour in the years after the alcohol experience intervention program they attended, i.e. the incidence of actually driving under the influence of alcohol. To do this, a questionnaire was sent to a subset (415) of the participants who have completed the program, along with a control group (450), to compare attitudes and actual behaviour. In addition, the Public Prosecutor checked the files of those who responded, for the occurrence of driving under the influence of alcohol. The group that participated in the alcohol intervention program showed more awareness about the dangers of driving while intoxicated than the control group, and this group reported improved alcohol law compliance. Furthermore, less participants in the intervention program than in the control group were present in the Public Prosecutor files, respectively 0.7% and 4.2%. Hence, the alcohol driving experience intervention program might turn out to be effective and successful in decreasing driving under the influence of alcohol. Although the results of the present study are no more than suggestive, they may be considered a first step towards demonstrating the effectiveness of this type of intervention. However, the intervention is unique and warrants a more robust evaluation. A large-sized randomized controlled trial should be conducted in the next phase to confirm the findings that the intervention program is a suitable educational tool to decrease driving under the influence of alcohol. The present paper serves to raise awareness of this intervention and its potential. Copyright © 2010 Elsevier Ltd. All rights reserved.

Public health agencies at the federal, state, and local level are responsible for implementing actions and policies that address health problems related to environmental hazards. These actions and policies can be informed by integrating or linking data on health, exposure, hazards, and population. The mission of the Centers for Disease Control and Prevention׳s National Environmental Public Health Tracking Program (Tracking Program) is to provide information from a nationwide network of integrated health, environmental hazard, and exposure data that drives actions to improve the health of communities. The Tracking Program and federal, state, and local partners collect, integrate, analyze, and disseminate data and information to inform environmental public health actions. However, many challenges exist regarding the availability and quality of data, the application of appropriate methods and tools to link data, and the state of the science needed to link and analyze health and environmental data. The Tracking Program has collaborated with academia to address key challenges in these areas. The collaboration has improved our understanding of the uses and limitations of available data and methods, expanded the use of existing data and methods, and increased our knowledge about the connections between health and environment. Valuable working relationships have been forged in this process, and together we have identified opportunities and improvements for future collaborations to further advance the science and practice of environmental public health tracking.

Injuries from motor vehicle crashes are a significant public health problem. The emergency department (ED) provides a setting that may be used to screen for behaviors that increase risk for motor vehicle crashes and provide brief interventions to people who might otherwise not have access to screening and intervention. The purpose of the present study was to (1) assess the feasibility of using a computer-assisted screening program to educate ED patients about risky driving behaviors, (2) evaluate patient acceptance of the computer-based traffic safety educational intervention during an ED visit, and (3) assess postintervention changes in risky driving behaviors. Pre/posteducational intervention involving medically stable adult ED patients in a large urban academic ED serving over 100,000 patients annually. Patients completed a self-administered, computer-based program that queried patients on risky driving behaviors (texting, talking, and other forms of distracted driving) and alcohol use. The computer provided patients with educational information on the dangers of these behaviors and data were collected on patient satisfaction with the program. Staff called patients 1 month post-ED visit for a repeat query. One hundred forty-nine patients participated, and 111 completed 1-month follow up (75%); the mean age was 39 (range: 21-70), 59 percent were Hispanic, and 52 percent were male. Ninety-seven percent of patients reported that the program was easy to use and that they were comfortable receiving this education via computer during their ED visit. All driving behaviors significantly decreased in comparison to baseline with the following reductions reported: talking on the phone, 30 percent; aggressive driving, 30 percent; texting while driving, 19 percent; drowsy driving, 16 percent; driving while multitasking, 12 percent; and drinking and driving, 9 percent. Overall, patients were very satisfied receiving educational information about these behaviors via computer during their ED visits and found the program easy to use. We found a high prevalence of self-reported risky driving behaviors in our ED population. At 1-month follow-up, patients reported a significant decrease in these behaviors. This study indicates that a low-intensity, computer-based educational intervention during an ED visit may be a useful approach to educate patients about safe driving behaviors and safe drinking limits and help promote behavior change.

Henry, Heather F; Suk, William A

2017-03-01

Innovative devices and tools for exposure assessment and remediation play an integral role in preventing exposure to hazardous substances. New solutions for detecting and remediating organic, inorganic, and mixtures of contaminants can improve public health as a means of primary prevention. Using a public health prevention model, detection and remediation technologies contribute to primary prevention as tools to identify areas of high risk (e.g. contamination hotspots), to recognize hazards (bioassay tests), and to prevent exposure through contaminant cleanups. Primary prevention success is ultimately governed by the widespread acceptance of the prevention tool. And, in like fashion, detection and remediation technologies must convey technical and sustainability advantages to be adopted for use. Hence, sustainability - economic, environmental, and societal - drives innovation in detection and remediation technology. The National Institute of Health (NIH) National Institute of Environmental Health Sciences (NIEHS) Superfund Research Program (SRP) is mandated to advance innovative detection, remediation, and toxicity screening technology development through grants to universities and small businesses. SRP recognizes the importance of fast, accurate, robust, and advanced detection technologies that allow for portable real-time, on-site characterization, monitoring, and assessment of contaminant concentration and/or toxicity. Advances in non-targeted screening, biological-based assays, passive sampling devices (PSDs), sophisticated modeling approaches, and precision-based analytical tools are making it easier to quickly identify hazardous "hotspots" and, therefore, prevent exposures. Innovation in sustainable remediation uses a variety of approaches: in situ remediation; harnessing the natural catalytic properties of biological processes (such as bioremediation and phytotechnologies); and application of novel materials science (such as nanotechnology, advanced membranes, new carbon materials, and materials reuse). Collectively, the investment in new technologies shows promise to reduce the amount and toxicity of hazardous substances in the environment. This manuscript highlights SRP funded innovative devices and tools for exposure assessment and remediation of organic, inorganic, and mixtures of contaminants with a particular focus on sustainable technologies.

In the United States, one third of all deaths in teens are a result of motor vehicle crashes, accounting for 6,000 deaths annually. Injury Free Coalition for Kids-Worcester in collaboration with Worcester Juvenile Court has developed an interactive program for first-time teenaged driving offenders, Reality Intensive Driver Education (Teen RIDE). This full-day program at the trauma center provides a realistic exposure to the consequences of risky driving behaviors. This article examined the driving offense recidivism rates for Teen RIDE participants versus a comparison group (CG). The intervention group (IG) consists of teenagers between 13 years and 17 years who have been arrested for the first time for a serious driving offense and are sentenced by a Worcester Juvenile Court Judge or Magistrate to the Teen RIDE program. They are required to attend the program as a condition of probation, so attendance is mandatory. Each participant in the IG completed the program and was tracked for driving reoffenses for 6 months after completion of the course. The CG consists of also first-time driving offenders. The CG was matched with the IG with respect to age (13-17 years), sex, and offense type. Springfield, Massachusetts, serves as the site for recruitment of the CG, since it is demographically similar to Worcester but 60 mi away. Students in the CG had no exposure to this program. Each CG member was also tracked for 6 months after arrest. The recidivism rate for Teen RIDE participants 6 months after the course is 6% with 0% reoffending more than once. The CG has a recidivism rate of 56% 6 months after the arrest and 14% have more than one reoffense. The CG is 13.062 (4.296-39.713) times more likely to reoffend, and this is significant (p < 0.001). The Teen RIDE program provides an impactful exposure of the consequences of risky driving behaviors to teenaged participants. In addition, Teen RIDE participants are significantly less likely to reoffend after completion of the course. Therapeutic study, level III.

A Note on the Effectiveness of the House-Arrest Alternative for Motivating DWI Offenders to Install Ignition Interlocks

Problem The effectiveness of ignition interlocks at reducing drunk driving has been limited by the ability of driving-while-intoxicated (DWI) offenders to avoid court orders to install the devices. Methods In a pilot program in New Mexico, four Santa Fe County judges imposed home confinement (via electronic monitoring bracelets) on offenders who claimed to have no car or no intention to drive. Interlock installation rates for Santa Fe County were compared with all other counties in New Mexico over a 2-year program and 2-year post-program period. Results During the two program years, 70% of the drivers convicted of DWI in Santa Fe County installed interlocks, compared to only 17% in the other counties, but when the program was terminated, the Santa Fe installation rate fell by 18.8 percentage points. Summary Mandating the alternative sanction of house arrest led to the highest reported interlock installation rate for DWI offenders. Impact on Industry Impaired driving is a substantial expense to employers, particularly when it bars driving that interferes with employment. Interlocks provide a method of protecting the public while permitting the offender to drive sober. This study was directed at increasing interlock use by DWI offenders. PMID:19945556

Injury is the leading cause of death in children. Although many pediatric hospitals and trauma centers provide injury prevention (IP) programming, there is no national standard. This study aims to identify characteristics of a sustainable and successful IP program by querying programs affiliated with the Injury Free Coalition for Kids (IFCK). The IFCK sites were sent a 30-question survey via e-mail. Questions focused on demographics, scope of IP activities, self-efficacy, and outcome measures including finances, academic productivity, and legislative advocacy. Counts and frequencies were calculated and compared using χ tests. The survey was completed by 38 (90.4%) of 42 sites. The majority were associated with a freestanding children's hospital (57.9%) and Level I pediatric trauma center (86.8%). Most programs (79%) had at least one dedicated full-time equivalent (FTE) staff. Research was most common on child passenger safety and teen driving. Nearly 30% of programs offered educational curricula to health care providers; these sites were more likely to have FTE support (p = 0.036). Steady sources of funding were identified for 60.5% of programs, with 47.8% citing their hospital as the primary source; 73% of respondents were confident in their program's capacity to sustain activities; these were more likely to be larger programs (p = 0.001) with steady sources of funding (p < 0.001). Despite 73.7% of sites having academic affiliations, 60.5% had 5 or fewer publications over the previous 5 years. In the prior 2 years, 55.3% of programs impacted legislative or policy changes. Funding, size of program, and FTE had no statistical correlation with research productivity or number of legislative/policy contributions. This study characterizes the variation among pediatric IP programs within IFCK sites, while highlighting the association between financial and FTE support from programs' institutions with sustainable IP programming. These results can assist programs in identifying differences in relation to their peers.

To examine the association between self assessed driving while sleepy and the risk of serious road traffic accidents (RTAs). Prospective cohort study. France. 13 299 of the 19 894 living members of the GAZEL cohort, workers and recent retirees of a French national utility company followed up since 1989. Frequency of driving while sleepy in the previous 12 months, reported in 2001; rate ratios for serious RTAs in 2001-3, estimated by using generalised linear Poisson regression models with time dependent covariates. The risk of serious RTAs increased proportionally with the frequency of self reported driving while sleepy. After adjustment for sociodemographic characteristics, driving behaviour variables, work conditions, retirement, medical conditions and treatments, depressive symptoms, and sleep disorders, the adjusted rate ratios of serious RTAs for participants who reported driving while sleepy in the previous 12 months "a few times" or "once a month or more often" were 1.5 (95% confidence interval 1.2 to 2.0) and 2.9 (1.3 to 6.3) respectively compared with those who reported not driving while sleepy over the same period. These associations were not explained by any reported sleep disorders. Self assessed driving while sleepy was a powerful predictor of serious RTAs, suggesting that drivers' awareness of their sleepiness while driving is not sufficient to prevent them from having RTAs. Messages on prevention should therefore focus on convincing sleepy drivers to stop driving and sleep before resuming their journey.

Previous findings suggest that alcohol alters perceptions of risky behaviors such as drinking and driving. However, studies testing these perceptions as a predictor of drinking and driving typically measure these perceptions while participants are sober. This study tested whether the perceived danger of driving after drinking assessed while intoxicated was associated with increased willingness to drive and self-reported drinking-and-driving behavior over and above perceptions assessed while sober. Additionally, we tested the effect of acute tolerance on the perceived danger of driving after drinking assessed on the ascending and descending limbs of the breath alcohol concentration (BrAC) curve. Eighty-two young adults attended 2 counterbalanced laboratory sessions. In one session, participants consumed a moderate dose of alcohol (men: 0.72 g/kg, women: 0.65 g/kg) and reported their perceived danger of driving and willingness to drive at multiple points across the BrAC curve. On a separate occasion, participants remained sober and appraised the dangerousness of driving at a hypothetical, illegal BrAC. Perceptions of the dangerousness of driving following alcohol administration were associated with increased willingness to drive and higher rates of self-reported drinking-and-driving behavior over and above perceptions reported when sober. Furthermore, perceived danger was reduced on the descending limb of the BrAC curve, compared with the ascending limb, suggesting the occurrence of acute tolerance. Results from this study suggest that intoxicated perceptions are uniquely associated with drinking-and-driving decisions and that the perceived danger of drinking and driving is lower on the descending limb of the BrAC curve. Efforts to prevent alcohol-impaired driving have focused on increasing awareness of the danger of driving after drinking. Prevention efforts may be enhanced by educating drivers about how intoxication can alter perceived danger, and interventions may benefit from targeting perceptions of dangerousness while individuals are intoxicated in addition to when they are sober.

Perceptual and cognitive disorders that frequently accompany stroke and head injury influence an individual's ability to drive a motor vehicle. Canadian physicians are legally responsible for identifying patients who are potentially unsafe to drive and, if they fail to do so, may be held liable in a civil action suit. The authors review the guidelines for physicians evaluating a patient's fitness to drive after brain injury. They also examine the actions a physician should take when a patient with perceptual and cognitive problems wants to drive. Ultimately, by taking these actions, physicians will help to prevent driving accidents. PMID:21234047

ΔNp63α promotes breast cancer cell motility through the selective activation of components of the epithelial-to-mesenchymal transition program

Cell identity signals influence the invasive capability of tumor cells, as demonstrated by the selection for programs of epithelial-to-mesenchymal transition (EMT) during malignant progression. Breast cancer cells retain canonical epithelial traits and invade collectively as cohesive groups of cells, but the signaling pathways critical to their invasive capabilities are still incompletely understood. Here we report that the transcription factor ΔNp63α drives the migration of basal-like breast cancer (BLBC) cells by inducing a hybrid mesenchymal/epithelial state. Through a combination of expression analysis and functional testing across multiple BLBC cell populations, we determined that ΔNp63α induces migration by elevating the expression of the EMT program components Slug and Axl. Interestingly, ΔNp63α also increased the expression of miR205, which can silence ZEB1/2 to prevent the loss of epithelial character caused by EMT induction. In clinical specimens, co-expression of various elements of the ΔNp63α pathway confirmed its implication in motility signaling in BLBC. We observed that activation of the ΔNp63α pathway occurred during the transition from noninvasive ductal carcinoma in situ to invasive breast cancer. Notably, in an orthotopic tumor model, Slug expression was sufficient to induce collective invasion of E-cadherin expressing BLBC cells. Together, our results illustrate how ΔNp63α can drive breast cancer cell invasion by selectively engaging pro-migratory components of the EMT program while, in parallel, still promoting the retention of epithelial character.

Digital interventions to reduce risk behaviours are emerging as effective public health measures; however, few have been applied to drink driving and associated alcohol use based on a harm reduction perspective. This paper reports on the design, development, and pilot of a novel intervention which aims to reduce repeat offending by first-time convicted drink driving offenders. It explores whether an online program is acceptable and user friendly and contains useful and relevant content, with a sample of first-time drink driving offenders recruited at the time of conviction. Building upon existing research into interventions to reduce drink driving recidivism and problem alcohol use, a tailored program was designed to provide content specifically concerned with drink driving and with an additional component related to alcohol use. Following stakeholder and internal review, the 'Steering Clear First Offender Drink Driving Program' was subsequently piloted with 15 first-time drink driving offenders. Evaluative data was analysed both quantitatively and qualitatively. The pilot results indicate that the participants found the program to be user friendly, as demonstrated by high scores in relation to navigation, online delivery, engagement, avatar usage and straightforwardness. They reported that they found the content to be useful and relevant and that the key learning area was in relation to the consequences of drink driving. Online interventions for reducing risky behaviour such as drink driving may be useful and cost effective from a public health perspective. Potentially, they can directly address risky behaviours associated with alcohol use in high-risk cohorts that may not ordinarily receive intervention.

Crashes are the leading cause of death for teens, and parent-based interventions are a promising approach. We assess the effectiveness of Steering Teens Safe, a parent-focused program to increase safe teen driving. Steering Teens Safe aimed to improve parental communication with teens about safe driving using motivational interviewing techniques in conjunction with 19 safe driving lessons. A randomized controlled trial involved 145 parent-teen dyads (70 intervention and 75 control). Intervention parents received a 45-minute session to learn the program with four follow-up phone sessions, a DVD, and a workbook. Control parents received a standard brochure about safe driving. Scores were developed to measure teen-reported quantity and quality of parental communication about safe driving. The main outcome measure was a previously validated Risky Driving Score reported by teens. Because the Score was highly skewed, a generalized linear model based on a gamma distribution was used for analysis. Intervention teens ranked their parent's success in talking about driving safety higher than control teens (p = 0.035) and reported that their parents talked about more topics (non-significant difference). The Risky Driving Score was 21% lower in intervention compared to control teens (85% CI = 0.60, 1.00). Interaction between communication quantity and the intervention was examined. Intervention teens who reported more successful communication had a 42% lower Risky Driving Score (95% CI = 0.37, 0.94) than control parents with less successful communication. This program had a positive although not strong effect, and it may hold the most promise in partnership with other programs, such as Driver's Education or Graduated Driver's License policies.

In 1998, Ontario implemented a remedial program called "Back On Track" (BOT) for individuals convicted of alcohol-impaired driving. Drivers convicted before October 2000 were exposed to a single-component program ("Edu BOT"); those convicted after participated in a multi-component program ("Full BOT"). We evaluated the impact of BOT, and the preceding 90-day roadside licence suspension, on drinking and driving recidivism, an outcome yet to be examined, using population-wide driver records. A Chi Square Test was used to compare the three-year cumulative incidence of recidivism between three historically-defined cohorts: No BOT, Edu BOT, and Full BOT. Stratified analyses by completion status and by age were also conducted. Analyses of the roadside suspension were conducted using an interrupted time series approach based on segmented Poisson/negative binomial regression. The roadside suspension was associated with a 65.2% reduction in drinking driving recidivism. In combination with indefinite suspensions for non-completion, the BOT program was also associated with a 21% decrease in drinking and driving recidivism in the three years following a CCC driving prohibition, from 8.5% to 6.7%. This reduction cannot be explained by pre-existing trends in recidivism. Conversion of the BOT program from the single-component version to the multi-component program further reduced the three-year cumulative incidence of recidivism to 5.5% (a total reduction of 35% from pre-BOT). Results provide strong converging evidence that remedial alcohol education/treatment programs in combination with other sanctions can produce substantial increases in road safety.

2011-05-01

The use of the social marketing approach for public health issues is increasing. This approach uses marketing concepts borrowed from the principles of commercial marketing to promote beneficial health behaviors. In this qualitative study, four focus groups involving 42 participants were used in consumer research to explore taxi drivers' views on the driving situation and the determinants of risky driving behaviors in Tehran, as well as to gather their ideas for developing a social marketing program to reduce risky driving behaviors among taxi drivers in Tehran, Iran. Participants were asked to respond to questions that would guide the development of a marketing mix, or four Ps (product, price, place and promotion). The discussions determined that the program product should involve avoiding risky driving behaviors through increased attention to driving. They pointed out that developing and communicating with a well-designed persuasive message meant to draw their attention to driving could affect their driving behaviors. In addition, participants identified price, place and promotion strategies. They offered suggestions for marketing nonrisky driving to the target audience. The focus group discussions generated important insights into the values and the motivations that affect consumers' decisions to adopt the product. The focus group guided the development of a social marketing program to reduce risky driving behaviors in taxi drivers in Tehran, Iran. Copyright © 2010 Elsevier Ltd. All rights reserved.

Motor Drive Technologies for the Power-by-Wire (PBW) Program: Options, Trends and Tradeoffs

Elbuluk, Malik E.; Kankam, M. David

1995-01-01

Power-By-Wire (PBW) is a program involving the replacement of hydraulic and pneumatic systems currently used in aircraft with an all-electric secondary power system. One of the largest loads of the all-electric secondary power system will be the motor loads which include pumps, compressors and Electrical Actuators (EA's). Issues of improved reliability, reduced maintenance and efficiency, among other advantages, are the motivation for replacing the existing aircraft actuators with electrical actuators. An EA system contains four major components. These are the motor, the power electronic converters, the actuator and the control system, including the sensors. This paper is a comparative literature review in motor drive technologies, with a focus on the trends and tradeoffs involved in the selection of a particular motor drive technology. The reported research comprises three motor drive technologies. These are the induction motor (IM), the brushless dc motor (BLDCM) and the switched reluctance motor (SRM). Each of the three drives has the potential for application in the PBW program. Many issues remain to be investigated and compared between the three motor drives, using actual mechanical loads expected in the PBW program.

Facebook photo activity associated with body image disturbance in adolescent girls.

PubMed

Meier, Evelyn P; Gray, James

2014-04-01

The present study examined the relationship between body image and adolescent girls' activity on the social networking site (SNS) Facebook (FB). Research has shown that elevated Internet "appearance exposure" is positively correlated with increased body image disturbance among adolescent girls, and there is a particularly strong association with FB use. The present study sought to replicate and extend upon these findings by identifying the specific FB features that correlate with body image disturbance in adolescent girls. A total of 103 middle and high school females completed questionnaire measures of total FB use, specific FB feature use, weight dissatisfaction, drive for thinness, thin ideal internalization, appearance comparison, and self-objectification. An appearance exposure score was calculated based on subjects' use of FB photo applications relative to total FB use. Elevated appearance exposure, but not overall FB usage, was significantly correlated with weight dissatisfaction, drive for thinness, thin ideal internalization, and self-objectification. Implications for eating disorder prevention programs and best practices in researching SNSs are discussed.

Drinking and other risk taking behaviors of enlisted male soldiers in the US Army

Williams, Jeffrey O.; Bell, Nicole S.; Amoroso, Paul J.

2007-01-01

High-risk drinking is among the top three prevention priorities of the Department of Defense. Research suggests that enlisted male soldiers are particularly at risk for unhealthy drinking behaviors. 292,023 enlisted male soldiers who responded to a Health Risk Appraisal (HRA) survey between 1990 and 1998 were dichotomized into high and low-risk drinking groups. Logistic regression analysis showed that high-risk drinkers wore seatbelts less frequently, were more likely to drive > 15 mph over the speed limit, and to smoke more than 20 cigarettes/day. This high-risk group was predominately young (< 25), Caucasian, high school educated or less, and most likely employed as infantrymen or craftsworkers. The two highest risk occupational groups (infantrymen and craftsworkers) differ from each other, and from other Army occupations. Intervention programs should include safe driving habits and smoking cessation, as well as high-risk drinking, and should be tailored to the specific needs of the group at highest risk.

Young drivers in Israel, as in other parts of the world, are involved in car crashes more than any other age group. The graduated driver licensing system in Israel requires that all new drivers be accompanied by an experienced driver whenever they drive for the first 3 months after obtaining a driving license. In an effort to make the accompanied driving phase more effective, a novel program which targets both young drivers and their parents was initiated in 2005. The program administers a personal meeting with the young driver and the accompanying parent scheduled for the beginning of the accompanied driving phase. In this meeting guidance is given regarding best practices for undertaking the accompanied driving, as well as tips for dealing with in-vehicle parent-teen dynamics. Through 2008, almost 130,000 families of young drivers have participated in the program. In order to evaluate the effectiveness of the program, injury crash records of the young drivers who participated in the program were compared with those of all other young drivers that were licensed at the same time period. The results obtained indicate statistically significant lower crash records for young drivers that participated in the program. Limitations of the evaluation related to self-selection biases are discussed, and practical implications are suggested. Copyright © 2011 Elsevier Ltd. All rights reserved.

Eating knowledge, nutritional knowledge, and psychological changes among female collegiate dancers were examined before and after a 4-wk. team-centered program on sport nutrition, exercise, and disordered eating consequences. Collegiate female dancers from two NCAA Division I institutions participated in a control (n = 19; M age = 19.1 yr., SD = 1.0) or intervention (n = 21; M age = 19.2 yr., SD = 1.2) group. Measures were administered to both groups before and after intervention to assess eating disorders, depression, and nutritional and disordered eating knowledge. There was a statistically significant increase in scores on nutritional and overall eating disorder knowledge in the intervention group compared to the control group. Mean scores on depression, drive for thinness, body dissatisfaction, and maturity fears decreased in the intervention group.

Saturday Driving Restrictions Fail to Improve Air Quality in Mexico City.

PubMed

Davis, Lucas W

2017-02-02

Policymakers around the world are turning to license-plate based driving restrictions in an effort to address urban air pollution. The format differs across cities, but most programs restrict driving once or twice a week during weekdays. This paper focuses on Mexico City, home to one of the oldest and best-known driving restriction policies. For almost two decades Mexico City's driving restrictions applied during weekdays only. This changed recently, however, when the program was expanded to include Saturdays. This paper uses hourly data from pollution monitoring stations to measure the effect of the Saturday expansion on air quality. Overall, there is little evidence that the program expansion improved air quality. Across eight major pollutants, the program expansion had virtually no discernible effect on pollution levels. These disappointing results stand in sharp contrast to estimates made before the expansion which predicted a 15%+ decrease in vehicle emissions on Saturdays. To understand why the program has been less effective than expected, the paper then turns to evidence from subway, bus, and light rail ridership, finding no evidence that the expansion was successful in getting drivers to switch to lower-emitting forms of transportation.

Delgado, M Kit; Wanner, Kathryn J; McDonald, Catherine

2016-06-16

Motor vehicle crashes are the leading cause of death in adolescents, and drivers aged 16-19 are the most likely to die in distracted driving crashes. This paper provides an overview of the literature on adolescent cellphone use while driving, focusing on the crash risk, incidence, risk factors for engagement, and the effectiveness of current mitigation strategies. We conclude by discussing promising future approaches to prevent crashes related to cellphone use in adolescents. Handheld manipulation of the phone while driving has been shown to have a 3 to 4-fold increased risk of a near crash or crash, and eye glance duration greater than 2 seconds increases crash risk exponentially. Nearly half of U.S. high school students admit to texting while driving in the last month, but the frequency of use according to vehicle speed and high-risk situations remains unknown. Several risk factors are associated with cell phone use while driving including: parental cellphone use while driving, social norms for quick responses to text messages, and higher levels of temporal discounting. Given the limited effectiveness of current mitigation strategies such as educational campaigns and legal bans, a multi-pronged behavioral and technological approach addressing the above risk factors will be necessary to reduce this dangerous behavior in adolescents.

Chronic sequelae of diabetes that could potentially affect driving include the following: visual retinopathy with associated impaired visual acuity, loss of peripheral vision and poor dark adaptation; neuropathy that may affect lower limb functions needed for safe driving; and acute events, including transient cognitive dysfunction and loss of consciousness related to hypo- or hyperglycemia. Hyperglycemia does not suddenly incapacitate drivers, however its occurrence often leads to tiredness, blurred vision, decreased visual acuity and adjustment of treatment which may precipitate hypoglycaemia. The side effects of acute hypoglycemia are of particular concern, as they include slowing of both cognitive and motor functions. Hypoglycemia while driving ist the most important complication in persons treated with insulin, sulfonylureas or glinides. They can be prevented, however, by frequent measuring blood glucose before and every 60 to 90 minutes during driving, by keeping sugary snacks (carbohydrates) in the vehicle, and by taking carbohydrates in case of glucose levels below 5 mmol/l. For patients, who are treated with insulin and sulfonylureas/glinides, it is of utmost importance fort the treating physician to frequently talk about successful strategies for preventing hypoglycemias, and thus accidents, while driving. People with diabetes treated with insulin, sulfonylureas or glinides are nor allowed to drive a bus, taxi, or truck (commercial driving). Under special circumstances (evalution and treatment by a diabetologist/endocrinolgist, avoidance of hypoglycemias for three months, and frequent glucose measurements) an exception to this rule can be granted for truck and cab drivers (after a thorough licensing examination).

To examine pre-licensure agreement on driving expectations and predictors of teen driving expectations among parent-teen dyads. Cross-sectional survey of 163 parent-teen dyads. Descriptive statistics, weighted Kappa coefficients, and linear regression were used to examine expectations about post-licensure teen driving. Teens reported high pre-licensure unsupervised driving (N = 79, 48.5%) and regular access to a car (N = 130, 81.8%). Parents and teens had low agreement on teen driving expectations (eg, after dark, κw = 0.23). Each time teens currently drove to/from school, their expectation of driving in risky conditions post-licensure increased (β = 0.21, p = .02). Pre-licensure improvement of parent-teen agreement on driving expectations are needed to have the greatest impact on preventing teens from driving in high risk conditions.

Media matters for boys too! The role of specific magazine types and television programs in the drive for thinness and muscularity in adolescent boys.

This study examined the role of specific magazine types and television programs on drive for thinness and muscularity in adolescent boys. A sample of 182 adolescent boys with an average age of 15.2 years completed questionnaire measures of magazine and television consumption, drive for thinness and drive for muscularity. Different media genres showed varying relationships with drive for thinness and muscularity. Specifically, the consumption of men's magazines and the viewing of soap operas emerged as significant unique predictors of drive for thinness, with the consumption of men's magazines also offering unique prediction of drive for muscularity. A comprehensive approach that considers both type and genre of media is critical in increasing our understanding of the complex relationships between media exposure and disordered eating in adolescent boys.

2012-03-01

This research is aimed at examining the added value of using Virtual Reality (VR) in a driving simulator to prevent road accidents, specifically by improving drivers' skills when confronted with extreme situations. In an experiment, subjects completed a driving scenario using two platforms: A 3-D Virtual Reality display system using an HMD (Head-Mounted Display), and a standard computerized display system based on a standard computer monitor. The results show that the average rate of errors (deviating from the driving path) in a VR environment is significantly lower than in the standard one. In addition, there was no compensation between speed and accuracy in completing the driving mission. On the contrary: The average speed was even slightly faster in the VR simulation than in the standard environment. Thus, generally, despite the lower rate of deviation in VR setting, it is not achieved by driving slower. When the subjects were asked about their personal experiences from the training session, most of the subjects responded that among other things, the VR session caused them to feel a higher sense of commitment to the task and their performance. Some of them even stated that the VR session gave them a real sensation of driving.

High-speed low-power voltage-programmed driving scheme for AMOLED displays

A new voltage-programmed driving scheme named the mixed parallel addressing scheme is presented for AMOLED displays, in which one compensation interval can be divided into the first compensation frame and the consequent N -1 post-compensation frames without periods of initialization and threshold voltage detection. The proposed driving scheme has the advantages of both high speed and low driving power due to the mixture of the pipeline technology and the threshold voltage one-time detection technology. Corresponding to the proposed driving scheme, we also propose a new voltage-programmed compensation pixel circuit, which consists of five TFTs and two capacitors (5T2C). In-Zn-O thin-film transistors (IZO TFTs) are used to build the proposed 5T2C pixel circuit. It is shown that the non-uniformity of the proposed pixel circuit is considerably reduced compared with that of the conventional 2T1C pixel circuit. The number of frames (N) preserved in the proposed driving scheme are measured and can be up to 35 with the variation of the OLED current remaining in an acceptable range. Moreover, the proposed voltage-programmed driving scheme can be more valuable for an AMOLED display with high resolution, and may also be applied to other compensation pixel circuits.

Motor vehicle crashes are the leading cause of death among teen drivers. The main goal of this program was to reduce texting while driving among high school teens through a unique peer-generated anti-texting campaign. The program consisted of two phases. In phase 1, student leaders participated in a half-day, hospital-based experiential program that emphasized safe teen driving. In phase 2, these students conceptualized and implemented an anti-texting while driving campaign during the school year. The program enrolled 32 schools with 137 student participants in phase 1.This study uses a prospective quasi-experimental pre-post design. A presurvey and a follow-up online survey were used. Response rate was 81%. In phase 2, two rounds of observations of drivers were made near the participating schools at the beginning and end of the phase 2 campaign. The results were analyzed using proportion tests. There was a strong belief (6.49 on a seven-point scale) that texting while driving could result in a crash. About 58% had texted while driving in the previous 7 days in the pre-survey. This proportion decreased significantly to 44% in the follow-up (p < 0.05). Knowledge of Tennessee Graduated Driver Licensing laws and feeling of empowerment to take action with a teen driver who was texting improved significantly (p < 0.05). In phase 2, 12,309 drivers (adults and teens) were observed in the first round, and 13,153 were observed in the second round of observations. Significant reduction in the proportion of drivers texting while driving (from 13% to 9%; p < 0.0001) was observed. Results of driver observations support the effectiveness of this program in meeting the key objective of reducing texting while driving. The program also influenced teenagers' willingness to take positive steps when faced with a driver who was texting. Future efforts should aim to influence social and peer norms.

Forgiveness and Consideration of Future Consequences in Aggressive Driving

PubMed Central

Moore, Michael; Dahlen, Eric R.

2008-01-01

Most research on aggressive driving has focused on identifying aspects of driver personality which will exacerbate it (e.g., sensation seeking, impulsiveness, driving anger, etc.). The present study was designed to examine two theoretically relevant but previously unexplored personality factors predicted to reduce the risk of aggressive driving: trait forgiveness and consideration of future consequences. The utility of these variables in predicting aggressive driving and driving anger expression was evaluated among 316 college student volunteers. Hierarchical multiple regressions permitted an analysis of the incremental validity of these constructs beyond respondent gender, age, miles driven per week, and driving anger. Both forgiveness and consideration of future consequences contributed to the prediction of aggressive driving and driving anger expression, independent of driving anger. Research on aggressive driving may be enhanced by greater attention to adaptive, potentially risk-reducing traits. Moreover, forgiveness and consideration of future consequences may have implications for accident prevention. PMID:18760093

Increasing proportion of the elderly in the driving population raises the importance of assuring their safety. We explored the effects of three different types of cognitive training on the cognitive function, brain structure, and driving safety of the elderly. Thirty-seven healthy elderly daily drivers were randomly assigned to one of three training groups: Group V trained in a vehicle with a newly developed onboard cognitive training program, Group P trained with a similar program but on a personal computer, and Group C trained to solve a crossword puzzle. Before and after the 8-week training period, they underwent neuropsychological tests, structural brain magnetic resonance imaging, and driving safety tests. For cognitive function, only Group V showed significant improvements in processing speed and working memory. For driving safety, Group V showed significant improvements both in the driving aptitude test and in the on-road evaluations. Group P showed no significant improvements in either test, and Group C showed significant improvements in the driving aptitude but not in the on-road evaluations. The results support the effectiveness of the onboard training program in enhancing the elderly's abilities to drive safely and the potential advantages of a multimodal training approach.

Processing of cognition, affect, and intention was investigated in viewers of advertisements to prevent speeding while driving. Results indicated that anchoring-point messages had greater effects on viewers' cognition, attitude, and behavioral intention than did messages without anchoring points. Further, the changes in message anchoring points altered participants' perceptions of acceptable and unacceptable judgments: a higher anchoring point in the form of speeding mortality was more persuasive in promoting the idea of reducing driving speed. Implications for creation of effective safe driving communications are discussed.

To promote workers' health and boost corporate productivity and national competitiveness, workplace health promotion is an international trend and a vital part of national policies. Prior to 2000, Taiwan's workplace issues focused on industrial hygiene and safety improvements. Since 2003, the Health Promotion Administration (HPA) at the Ministry of Health and Welfare has established coaching centers for workplace health promotion and dispatched trained experts for teaching health promotion skills; including promoting the tobacco control program, preventing important chronic diseases, driving comprehensive programs, advocating workplace health promotion with the Ministry of Labor, establishing certification mechanisms for workplace health promotion, recognizing outstanding health-promoting workplaces, and conducting a nationwide survey for monitoring the practices of healthy behaviors and health conditions of workers. Through 2014, 12,439 workplaces have been accredited.Since 2003, the efforts of the HPA in workplace health promotion projects has shifted society's focus on workplace health from occupational diseases and injury prevention to workplace health promotion, resulting in the revision of the Occupational Safety and Health Act in 2013 by the Ministry of Labor to detail employers' responsibilities in protecting and promoting employees' health and well-being. © The Author(s) 2016.

Drive-away policing and situational crime prevention in China: an analysis of motorcycle ban (jinmo) policy in Guangzhou.

PubMed

Xu, Jianhua

2012-04-01

Using the example of motorcycle ban policy in Guangzhou, the capital of Guangdong province, this article examines how situational crime prevention strategies are used in contemporary urban China. The article argues that although a motorcycle ban policy may reduce motorcycle snatch theft (feiche qiangduo) in Guangzhou, it inevitably caused a problem of displacement. However, some types of displacement are desirable for local government. An argument about drive-away policing is proposed in this article to understand policing styles in contemporary China. In addition, the article argues that motorcycle ban, as a strategy to prevent snatch theft and robbery, is also a strategy to deal with the crisis in police legitimacy. Therefore, crime prevention in China has more social and political significance than just reducing crime.

Behind the wheel: community consultation informs adaptation of safe-transport program for older drivers.

Safe-transport is important to well-being in later life but balancing safety and independence for older drivers can be challenging. While self-regulation is a promising tool to promote road safety, more research is required to optimise programs. Qualitative research was used to inform the choice and adaptation of a safe-transport education program for older drivers. Three focus groups were conducted with older drivers living in northwest Sydney to explore four key areas related to driving in later life including aged-based licensing, stopping or limiting driving, barriers to driving cessation and alternative modes of transportation. Data were analysed using content analysis. Four categories emerged from the data; bad press for older drivers, COMPETENCE not age, call for fairness in licensing regulations, and hanging up the keys: It's complicated! Two key issues being (1) older drivers wanted to drive for as long as possible but (2) were not prepared for driving cessation; guided the choice and adaption of the Knowledge Enhances Your Safety (KEYS) program. This program was adapted for the Australian context and focus group findings raised the need for practical solutions, including transport alternatives, to be added. Targeted messages were developed from the data using the Precaution Adoption Process Model (PAPM), allowing the education to be tailored to the individual's stage of behaviour change. Adapting our program based on insights gained from community consultation should ensure the program is sensitive to the needs, skills and preferences of older drivers.

Novel Straight Road Driving Control of Power Assisted Wheelchair Based on Disturbance Estimation of Right and Left Wheels

NASA Astrophysics Data System (ADS)

Seki, Hirokazu; Sugimoto, Takeaki; Tadakuma, Susumu

This paper describes a novel straight road driving control scheme of power assisted wheelchair. Power assisted wheelchair which assists the driving force by electric motors is expected to be widely used as a mobility support system for elderly people and disabled people. The straight driving can be prevented by the road conditions such as branches, grass and carpets because the right and left wheels drive independently. This paper proposes a straight road driving control system based on the disturbance torque estimation. The proposed system estimates the difference of the driving torque by disturbance torque observer and compensates to one side of the wheels. Some practical driving experiments on various road conditions show the effectiveness of the proposed control system.

Regulated mechanisms of stem cell maintenance are key to preventing stem cell depletion and aging. While mitochondrial morphology plays a fundamental role in tissue development and homeostasis, its role in stem cells remains unknown. Here, we uncover that mitochondrial dynamics regulates stem cell identity, self-renewal, and fate decisions by orchestrating a transcriptional program. Manipulation of mitochondrial structure, through OPA1 or MFN1/2 deletion, impaired neural stem cell (NSC) self-renewal, with consequent age-dependent depletion, neurogenesis defects, and cognitive impairments. Gene expression profiling revealed ectopic expression of the Notch self-renewal inhibitor Botch and premature induction of transcription factors that promote differentiation. Changes in mitochondrial dynamics regulate stem cell fate decisions by driving a physiological reactive oxygen species (ROS)-mediated process, which triggers a dual program to suppress self-renewal and promote differentiation via NRF2-mediated retrograde signaling. These findings reveal mitochondrial dynamics as an upstream regulator of essential mechanisms governing stem cell self-renewal and fate decisions through transcriptional programming.

2015-05-01

The high prevalence of trauma and post-traumatic stress disorder (PTSD) in individuals with substance use disorders (SUDs) presents a number of treatment challenges for community treatment providers and programs in the USA. Although several evidence-based, integrated therapies for the treatment of comorbid PTSD/SUD have been developed, rates of utilisation of such practices remain low in community treatment programs. The goal of this article was to review the extant literature on common barriers that prevent adoption and implementation of integrated treatments for PTSD/SUD among substance abuse community treatment programs. Organisational, provider-level and patient-level factors that drive practice decisions were discussed, including organisational philosophy of care policies, funding and resources, as well as provider and patient knowledge and attitudes related to implementation of new integrated treatments for comorbid PTSD and SUD. Understanding and addressing these community treatment challenges may facilitate use of evidence-based integrated treatments for comorbid PTSD and SUD. © 2015 Australasian Professional Society on Alcohol and other Drugs.

On Supplementing “Foot in the Door” Incentives for eHealth Program Engagement

PubMed Central

2014-01-01

Financial health incentives, such as paying people to lose weight, are being widely implemented by Western nations and large corporations. A growing number of studies have tested the impact of incentives on health behaviors, though few have evaluated the approach on a population-scale. In this issue of the Journal of Medical Internet Research, Liu et al add to the evidence-base by examining whether a single incentive can motivate enrollment and engagement in a preventive eHealth program in a sample of 142,726 Canadian adults. While the incentives increased enrollment significantly (by a factor of about 28), a very high level of program attrition was noted (90%). The “foot in the door” incentive technique employed was insufficient; enrollees received incentives for signing-up for, but not for engaging with, the eHealth program. To supplement this technique and drive sustained behavior change, several theoretically- and empirically-based strategies are proposed. Specifically, incentives indexed to behavioral achievements over time are highlighted as one approach to boost engagement in this population in the future. PMID:25092221

To describe levels of partnership between local health departments (LHDs) and other community organizations in maternal and child health (MCH), communicable disease prevention, and chronic disease control and to assess LHD organizational characteristics and community factors that contribute to partnerships. Data were drawn from the National Association of County & City Health Officials' 2013 National Profile Study (Profile Study) and the Area Health Resources File. LHDs that received module 1 of the Profile Study were asked to describe the level of partnership in MCH, communicable disease prevention, and chronic disease control. Levels of partnership included "not involved," "networking," "coordinating," "cooperating," and "collaborating," with "collaborating" as the highest level of partnership. Covariates included both LHD organizational and community factors. Data analyses were conducted using Stata 13 SVY procedures to account for the Profile Study's survey design. About 82%, 92%, and 80% of LHDs partnered with other organizations in MCH, communicable disease prevention, and chronic disease control programs, respectively. LHDs having a public health physician on staff were more likely to partner in chronic disease control programs (adjusted odds ratio [AOR] = 2.33; 95% confidence interval [CI], 1.03-5.25). Larger per capita expenditure was also associated with partnerships in MCH (AOR = 2.43; 95% CI, 1.22-4.86) and chronic disease prevention programs (AOR = 1.76; 95% CI, 1.09-2.86). Completion of a community health assessment was associated with partnership in MCH (AOR = 7.26; 95% CI, 2.90-18.18), and chronic disease prevention (AOR = 5.10; 95% CI, 2.28-11.39). About 1 in 5 LHDs did not have any partnerships in chronic disease control. LHD partnerships should be promoted to improve care coordination and utilization of limited health care resources. Factors that might promote LHDs' partnerships include having a public health physician on staff, higher per capita expenditure, and completion of a community health assessment. Community context likely influences types and levels of partnerships. A better understanding of these contextual factors may lead to more complete and effective LHD partnerships.

Alcohol-involved motor vehicle crashes are a major cause of preventable mortality in the U.S., leading to more than 10,000 fatalities in 2013. Ignition interlocks, or alcohol-sensing devices connected to a vehicle's ignition to prevent it from starting if a driver has a predetermined blood alcohol content (BAC) level, are a promising avenue for preventing alcohol-involved driving. This study sought to assess the effects of laws requiring ignition interlocks for some or all drunk driving offenders on alcohol-involved fatal crashes. A multilevel modeling approach assessed the effects of state interlock laws on alcohol-involved fatal crashes in the U.S. from 1982 to 2013. Monthly data on alcohol-involved crashes in each of the 50 states was collected in 2014 from the National Highway Traffic Safety Administration Fatality Analysis Reporting System. Random-intercept models accounted for between-state variation in alcohol-involved fatal crash rates and autocorrelation of within-state crash rates over time. Analysis was conducted in 2015. State laws requiring interlocks for all drunk driving offenders were associated with a 7% decrease in the rate of BAC >0.08 fatal crashes and an 8% decrease in the rate of BAC ≥0.15 fatal crashes, translating into an estimated 1,250 prevented BAC >0.08 fatal crashes. Laws requiring interlocks for segments of high-risk drunk driving offenders, such as repeat offenders, may reduce alcohol-involved fatal crashes after 2 years of implementation. Ignition interlock laws reduce alcohol-involved fatal crashes. Increasing the spread of interlock laws that are mandatory for all offenders would have significant public health benefit.

In many jurisdictions, a risk assessment following a first driving while impaired (DWI) offence is used to guide administrative decision making regarding driver relicensing. Decision error in this process has important consequences for public security on one hand, and the social and economic well being of drivers on the other. Decision theory posits that consideration of the costs and benefits of decision error is needed, and in the public health context, this should include community attitudes. The objective of the present study was to clarify whether Canadians prefer decision error that: i) better protects the public (i.e., false positives); or ii) better protects the offender (i.e., false negatives). A random sample of male and female adult drivers (N=1213) from the five most populated regions of Canada was surveyed on drivers' preference for a protection of the public approach versus a protection of DWI drivers approach in resolving assessment decision error, and the relative value (i.e., value ratio) they imparted to both approaches. The role of region, sex and age on drivers' value ratio were also appraised. Seventy percent of Canadian drivers preferred a protection of the public from DWI approach, with the overall relative ratio given to this preference, compared to the alternative protection of the driver approach, being 3:1. Females expressed a significantly higher value ratio (M=3.4, SD=3.5) than males (M=3.0, SD=3.4), p<0.05. Regression analysis showed that both days of alcohol use in the past 30days (CI for B: -0.07, -0.02) and frequency of driving over legal BAC limits in the past year (CI for B=-0.19, -0.01) were significantly but modestly related to lower value ratios, R 2 (adj.)=0.014, p<0.001. Regional differences were also detected. Canadian drivers strongly favour a protection of the public approach to dealing with uncertainty in assessment, even at the risk of false positives. Accounting for community attitudes concerning DWI prevention and the individual differences that influence them could contribute to more informed, coherent and effective regional policies and prevention program development.

Fatigued and drowsy driving: a survey of attitudes, opinions and behaviors.

2008-01-01

There is evidence suggesting that the problem of fatigued or drowsy driving is an important contributor to road crashes. However, not much is known about public perceptions of the issue. The purpose of this study was to obtain information on attitudes, opinions, and professed practices related to fatigued or drowsy driving. The data were gathered by means of a public opinion poll among a representative sample of 750 Ontario drivers. A majority of drivers (58.6%) admitted that they occasionally drive while fatigued or drowsy. Of greater importance, 14.5% of respondents admitted that they had fallen asleep or "nodded off" while driving during the past year. Nearly 2% were involved in a fatigue or drowsy driving related crash in the past year. Respondents were also asked about measures they take to overcome fatigue or drowsiness. Results indicate that relatively ineffective measures such as opening the window or playing music are the most popular; the most effective preventive measure--taking a rest--is the least popular. The prevalence of the behavior, coupled with the ineffective prevention measures favored by the public suggest there is a need for increasing their level of awareness and knowledge about the problem. Results from this study further emphasize the importance of increasing the fatigued and drowsy driving knowledge base and the need to educate the public about it.

Rotaviruses remain the major cause of childhood diarrheal disease worldwide and of diarrheal deaths of infants and children in developing countries. The huge burden of childhood rotavirus-related diarrhea in the world continues to drive the remarkable pace of vaccine development. Research articles were searched using terms "rotavirus" and "rotavirus vaccine" in MEDLINE and PubMed. Articles not published in the English language, articles without abstracts, and opinion articles were excluded from the review. After preliminary screening, all articles were reviewed and synthesized to provide an overview of current vaccines and vaccination programs. In this review of the global rotavirus vaccines and vaccination programs, the principles of rotavirus vaccine development and the efficacy of the currently licensed vaccines from both developed and developing countries were summarized. Rotavirus is a common cause of diarrhea in children in both developed and developing countries. Rotavirus vaccination is a cost-effective measure to prevent rotavirus diarrhea.

2010-01-01

The investigation of vehicle safety needs for older drivers and passengers is integral for their safe transportation. A program of research on safe transportation for seniors was launched through AUTO21, a Canadian Network of Centres of Excellence. This national research network focuses on a wide range of automotive issues, from materials and design to safety and societal issues. An inductive qualitative inquiry of seniors' driving experiences, safety feature use, and strategies to prevent injury and manage risks was a first step in this program. We conducted interviews and focus groups with 58 seniors without disabilities and 9 seniors with disabilities. We identified a lack of congruity between the vehicle and safety feature design and seniors' needs. Seniors described strategies to manage their safety and that of others. Specific aspects of vehicle design, safety features, and action strategies that support safer use and operation of a vehicle by seniors are outlined.

A randomized trial to evaluate the effectiveness of an individual, education-based safe transport program for drivers aged 75 years and older

PubMed Central

2013-01-01

Background There are concerns over safety of older drivers due to increased crash involvement and vulnerability to injury. However, loss of driving privileges can dramatically reduce independence and quality of life for older members of the community. The aim of this trial is to examine the effectiveness of a safe transport program for drivers aged 75 years and older at reducing driving exposure but maintaining mobility. Methods and design A randomised trial will be conducted, involving 380 drivers aged 75 years and older, resident in urban and semi-rural areas of North-West Sydney. The intervention is an education program based on the Knowledge Enhances Your Safety (KEYS) program, adapted for the Australian context. Driving experience will be measured objectively using an in-vehicle monitoring device which includes a global positioning system (GPS) to assess driving exposure and an accelerometer to detect rapid deceleration events. Participation will be assessed using the Keele Assessment of Participation (KAP). Data will be analysed on an intention-to-treat basis; the primary outcomes include driving exposure, rapid deceleration events and scores for KAP. Secondary outcomes include self-reported measures of driving, socialisation, uptake of alternative forms of transport, depressive symptoms and mood. A detailed process evaluation will be conducted, including examination of the delivery of the program and uptake of alternative forms of transport. A subgroup analysis is planned for drivers with reduced function as characterized by established cut-off scores on the Drivesafe assessment tool. Discussion This randomised trial is powered to provide an objective assessment of the efficacy of an individually tailored education and alternative transportation program to promote safety of older drivers but maintain mobility.

The burden of injuries due to drunk drivers has been estimated only indirectly. Indeed, alcohol is considered one of the most important contributing cause of car crash injuries and its effect on cognitive functions needs to be better elucidated. Aims of the study were i) to examine the effect of alcohol on attentive abilities involved while driving, and ii) to investigate whether Italian law limits for safe driving are sufficiently accurate to prevent risky behaviours and car crash risk while driving. We conducted a cross-over study at IRCCS Fondazione Santa Lucia Rehabilitation Hospital in Rome. Thirty-two healthy subjects were enrolled in this experiment. Participants were submitted to an attentive test battery assessing attention before taking Ethylic Alcohol (EA-) and after taking EA (EA+). In the EA+ condition subjects drank enough wine until the blood alcohol concentration, measured by means of Breath Analyzer, was equal to or higher than 0.5 g/l. Data analysis revealed that after alcohol assumption, tonic and phasic alertness, selective, divided attention and vigilance were significantly impaired when BAC level was at least 0.5 g/l. These data reveal that alcohol has a negative effect on attentive functions which are primarily involved in driving skills and that Italian law limits are adequate to prevent risky driving behaviour.

2017-01-01

Distracted driving is one of the most significant human factor issues in transport safety. Mobile phone interactions while driving may involve a multitude of cognitive and physical resources that result in inferior driving performance and reduced safety margins. The current study investigates characteristics of usage, risk factors, compensatory strategies in use and characteristics of high-frequency offenders of mobile phone use while driving. A series of questions were administered to drivers in Queensland (Australia) using an on-line questionnaire. A total of 484 drivers (34.9% males and 49.8% aged 17-25) participated anonymously. At least one of every two motorists surveyed reported engaging in distracted driving. Drivers were unable to acknowledge the increased crash risk associated with answering and locating a ringing phone in contrast to other tasks such as texting/browsing. Attitudes towards mobile phone usage were more favourable for talking than texting or browsing. Lowering the driving speed and increasing the distance from the vehicle in front were the most popular task-management strategies for talking and texting/browsing while driving. On the other hand, keeping the mobile phone low (e.g. in the driver's lap or on the passenger seat) was the favourite strategy used by drivers to avoid police fines for both talking and texting/browsing. Logistic regression models were fitted to understand differences in risk factors for engaging in mobile phone conversations and browsing/texting while driving. For both tasks, exposure to driving, driving experience, driving history (offences and crashes), and attitudes were significant predictors. Future mobile phone prevention efforts would benefit from development of safe attitudes and increasing risk literacy. Enforcement of mobile phone distraction should be re-engineered, as the use of task-management strategies to evade police enforcement seems to dilute its effect on the prevention of this behaviour. Some countermeasures and suggestions were proposed in the design of public education campaigns and driver-mobile phone interaction.

Driving is a meaningful occupation which is ascribed to functional independence in schizophrenia. Although it is estimated that individuals with schizophrenia have two times more traffic accidents, little research has been done in this field. Present research explores differences in mental status, visual working memory and visual organization between drivers and non-drivers with schizophrenia in comparison to healthy drivers. There were three groups in the study: 20 drivers with schizophrenia, 20 non-driving individuals with schizophrenia and 20 drivers without schizophrenia (DWS). Visual perception was measured with Rey-Osterrieth Complex Figure test and a general cognitive status with Mini-Mental State Examination. The general cognitive status predicted actual driving situation in people with schizophrenia. No statistically significant differences were found between driving and non-driving persons with schizophrenia on any of the visual parameters tested, although these abilities were significantly lower than those of DWS. The research demonstrates that impairment of visual abilities does not prevent people with schizophrenia from driving and emphasizes the importance of general cognitive status for complex and multidimensional everyday tasks. The findings support the need for further investigation in the field of car driving for this population - a move that will considerably contribute to the participation and well-being. Implication for Rehabilitation Unique approach for driving evaluation in schizophrenia should be designed since direct applications of knowledge and practice acquired from other populations are not reliable. This research demonstrates that visual perception deficits in schizophrenia do not prevent clients from driving, and general cognitive status appeared to be a valid determinant for actual driving. We recommended usage of a general test of cognition such as Mini-Mental State Examination, or conjunction number of cognitive factors such as executive functions (e.g., Trail Making Test) and attention (e.g., Continuous Performance Test) in addition to spatial-visual ability tests (e.g., Rey-Osterrieth Complex Figure test) for considering driving status in schizophrenia.

Motor vehicle accidents are the leading cause of death among youths and young adults aged 16-25 years in the United States (1). The prevalence of drinking and driving among high school students aged 16-19 years has declined by 54%, from 22.3% in 1991 to 10.3% in 2011 (2). However, the prevalence of weekend nighttime driving under the influence of marijuana (based on biochemical assays) among drivers aged ≥16 years has increased by 48%, from 8.6% in 2007 to 12.6% in 2013-2014 (3). Use of marijuana alone and in combination with alcohol has been shown to impair driving abilities (4-9). This report provides the most recent self-reported national estimates of driving under the influence of alcohol, marijuana, and alcohol and marijuana combined among persons aged 16-25 years, using data from the Substance Abuse and Mental Health Services Administration (SAMHSA) National Survey on Drug Use and Health (NSDUH) from 2002-2014. Prevalence data on driving under the influence of both substances were examined for two age groups (16-20 years and 21-25 years) and by sex and race/ethnicity. During 2002-2014, the prevalence of driving under the influence of alcohol alone significantly declined by 59% among persons aged 16-20 years (from 16.2% in 2002 to 6.6% in 2014; p<0.001) and 38% among persons 21-25 years (from 29.1% in 2002 to 18.1% in 2014; p<0.001). In addition, the prevalence of driving under the influence of alcohol and marijuana combined significantly declined by 39%, from 2.3% in 2002 to 1.4% in 2014 (p<0.001) among persons aged 16-20 years and from 3.1% in 2002 to 1.9% in 2014 (p<0.001) among persons aged 21-25 years. The prevalence of driving under the influence of marijuana alone declined 18%, from 3.8% in 2002 to 3.1% in 2014 (p = 0.05) only among persons aged 16-20 years. Effective public safety interventions,* such as minimum legal drinking age laws, prohibition of driving with any alcohol level >0 for persons aged <21 years, targeted mass media campaigns, roadside testing (e.g., sobriety checkpoints), and graduated driver licensing programs (10) have contributed to the decline in driving under the influence of alcohol in this population. These or similar interventions might be useful to prevent driving under the influence of other substances, such as marijuana alone or combined with other substances.

The 1990 National Academy of Science final report of its review of the Inertial Confinement Fusion Program recommended completion of a series of target physics objectives on the 10-beam Nova laser at the Lawrence Livermore National Laboratory as the highest-priority prerequisite for proceeding with construction of an ignition-scale laser facility, now called the National Ignition Facility (NIF). These objectives were chosen to demonstrate that there was sufficient understanding of the physics of ignition targets that the laser requirements for laboratory ignition could be accurately specified. This research on Nova, as well as additional research on the Omega laser at the University of Rochester, is the subject of this review. The objectives of the U.S. indirect-drive target physics program have been to experimentally demonstrate and predictively model hohlraum characteristics, as well as capsule performance in targets that have been scaled in key physics variables from NIF targets. To address the hohlraum and hydrodynamic constraints on indirect-drive ignition, the target physics program was divided into the Hohlraum and Laser-Plasma Physics (HLP) program and the Hydrodynamically Equivalent Physics (HEP) program. The HLP program addresses laser-plasma coupling, x-ray generation and transport, and the development of energy-efficient hohlraums that provide the appropriate spectral, temporal, and spatial x-ray drive. The HEP experiments address the issues of hydrodynamic instability and mix, as well as the effects of flux asymmetry on capsules that are scaled as closely as possible to ignition capsules (hydrodynamic equivalence). The HEP program also addresses other capsule physics issues associated with ignition, such as energy gain and energy loss to the fuel during implosion in the absence of alpha-particle deposition. The results from the Nova and Omega experiments approach the NIF requirements for most of the important ignition capsule parameters, including drive temperature, drive symmetry, and hydrodynamic instability. This paper starts with a review of the NIF target designs that have formed the motivation for the goals of the target physics program. Following that are theoretical and experimental results from Nova and Omega relevant to the requirements of those targets. Some elements of this work were covered in a 1995 review of indirect-drive [J. D. Lindl, ``Development of the indirect-drive approach to inertial confinement fusion and the target physics basis for ignition and gain,'' Phys. Plasmas 2, 3933 (1995)]. In order to present as complete a picture as possible of the research that has been carried out on indirect drive, key elements of that earlier review are also covered here, along with a review of work carried out since 1995.

Programs aimed at preventing violence against women have increasingly adopted bystander approaches, yet large gaps remain in our knowledge about what drives bystanders to act or not, particularly in settings where there is an increased risk of violence against women occurring. This article contributes to this gap by examining data from research with professional male athletes from the Australian Football League. Drawing from a mixed methods approach, including a survey and interviews with football players, we outline some of the challenges to bystander intervention faced by professional athletes and discuss some of the possible similarities and differences between these and other groups of men. © The Author(s) 2015.

To compare the effectiveness of a visual attention retraining program using the Useful Field of View (UFOV) with a traditional visuoperception treatment program on the driving performance of clients with stroke. Randomized controlled trial. Rehabilitation hospital located in Quebec, Canada. Ninety-seven individuals referred for driving evaluation after a stroke. Participants were randomized to receive 20 sessions of either UFOV training of visual processing speed, divided attention, and selective attention or traditional computerized visuoperception retraining. Subjects were evaluated with an on-road driving evaluation, visuoperception tests, and the Test of Everyday Attention. An occupational therapist unaware of group assignment conducted all evaluations. Eighty-four participants completed the outcome evaluation. There were no significant differences between groups on any of the outcome measures. There was, however, almost a 2-fold increase (52.4% vs 28.6%) in the rate of success on the on-road driving evaluation after UFOV training for subjects with right-sided lesions. Rehabilitation that targets visual attention skills was not significantly more beneficial than traditional perceptual training in improving the outcome of an on-road driving evaluation. However, results suggest a potential improvement for subjects with right-sided lesions, indicating that training must target specific skills.

A controlled intervention to promote a healthy body image, reduce eating disorder risk and prevent excessive exercise among trainee health education and physical education teachers.

This study examined the impact of two interventions on body image, eating disorder risk and excessive exercise among 170 (65% female) trainee health education and physical education (HE&PE) teachers of mean (standard deviation) age 21.6 (2.3) who were considered an 'at-risk' population for poor body image and eating disorders. In the first year of the study, the control group cohort (n = 49 females, 20 males) received the regular didactic health education curriculum; in the second year of the study, the Intervention 1 cohort (n = 31 females, 21 males) received a self-esteem and media literacy health education program and in the third year of the study, the Intervention 2 cohort (n = 30 females, 19 males) received a combined self-esteem, media literacy and dissonance program using online and computer-based activities. Intervention 2 produced the best results, with males improving significantly in self-esteem, body image and drive for muscularity. Intervention 2 females improved significantly on Eating Disorders Inventory Drive for Thinness, Eating Disorder Examination and excessive exercise. The improvements were consistent at 6-month follow-up for females. It is feasible to promote body image, reduce body dissatisfaction and reduce excessive exercise among trainee HE&PE teachers via a health education curriculum.

The role of the occupational physician is to prevent occupational accidents and diseases. Therefore, he is the one to decide if a worker is fit to drive in the context of his professional activity, including in cases where no specific driving license is required (e.g. forklift truck, mobile crane). This decision is an important one, as two thirds of fatal occupational accidents occur on the road. The decision is made on the basis of both a medical examination and the regulation, which indicates all contraindications to driving. The physician's responsibility is involved, as is the employer's, as he must ensure that his employee is fit to drive and possesses a valid driving license at all times.

Objective Teenage drivers diagnosed with attention-deficit/hyperactivity disorder (ADHD) are at significant risk for negative driving outcomes related to morbidity and mortality. However, there are few viable psychosocial treatments for teens with ADHD and none focus on the key functional area of driving. The Supporting the Effective Entry to the Roadway (STEER) program was evaluated in a clinical trial to determine whether it improved family functioning as a proximal outcome and driving behavior as a distal outcome. Method One hundred seventy-two teenagers with ADHD, combined type, were randomly assigned to STEER or a driver education driver practice program (DEDP). Results Relative to parents in the DEDP condition, parents in STEER were observed to be less negative at post-treatment and 6-month follow-up, but not at 12-month follow-up and there were no significant differences for observed positive parenting. Relative to teens in the DEDP condition, teens in STEER reported lower levels of risky driving behaviors at post-treatment and six-month follow-up, but not at 12-month follow-up. They were not observed to differ on objective observations of risky driving or citations/accidents. Conclusions The STEER program for novice drivers with ADHD was effective in reducing observations of negative parenting behavior and teen self reports of risky driving relative to DEDP; groups did not significantly differ on observations of positive parenting or driving behaviors. Public Health Significance Statement Families with a teenager with ADHD may benefit from engaging in behavioral parent training around the transition to independent driving, especially via reductions in negative parenting. Teenagers with ADHD self-reported fewer risky driving behaviors within the family-focused intervention, but these findings were not replicated on objective observations of driving. PMID:27618640

Objective Alcohol-impaired driving persists as a major cause of traffic fatalities and injuries among young drivers. This meta-analysis examined whether brief alcohol interventions were effective in reducing driving after drinking among adolescents and young adults. Method Our systematic search identified 12 experimental/quasi-experimental evaluations (16 intervention groups) that measured driving while intoxicated and related consequences and provided data for effect size calculation (N = 5,664; M age =17 years; 57% male). The studies were published between 1991 and 2011. Three-level random-effects meta-analyses using a structural equation modeling approach were used to summarize the effects of the interventions. Results Compared with controls, participants in brief alcohol interventions reported reduced drinking and driving and related consequences (ḡ = 0.15, 95% CI [0.08, 0.21]). Supplemental analyses indicated that reductions in driving while intoxicated were positively associated with the reduced post-intervention heavy use of alcohol. These findings were not attenuated by study design or implementation factors. Conclusions Brief alcohol interventions under 5 hours of contact may constitute a promising preventive approach targeting drinking and driving among adolescents and young adults. Reducing heavy episodic alcohol consumption appeared to be a major factor in reducing drunk-driving instances. Interpretation of the findings must be made with caution, however, given the possibility of publication bias and the small observed effect size. Future research should focus on the exact mechanisms of behavior change leading to beneficial outcomes of brief alcohol interventions and the potential effectiveness of combined brief interventions and other preventive approaches.

Fuzzy Inference Based Obstacle Avoidance Control of Electric Powered Wheelchair Considering Driving Risk

NASA Astrophysics Data System (ADS)

Kiso, Atsushi; Murakami, Hiroki; Seki, Hirokazu

This paper describes a novel obstacle avoidance control scheme of electric powered wheelchairs for realizing the safe driving in various environments. The “electric powered wheelchair” which generates the driving force by electric motors is expected to be widely used as a mobility support system for elderly people and disabled people; however, the driving performance must be further improved because the number of driving accidents caused by elderly operator's narrow sight and joystick operation errors is increasing. This paper proposes a novel obstacle avoidance control scheme based on fuzzy algorithm to prevent driving accidents. The proposed control system determines the driving direction by fuzzy algorithm based on the information of the joystick operation and distance to obstacles measured by ultrasonic sensors. Fuzzy rules to determine the driving direction are designed surely to avoid passers-by and walls considering the human's intent and driving environments. Some driving experiments on the practical situations show the effectiveness of the proposed control system.

Purpose of Review We reviewed papers published in 2012–2013 that focused on re-emerging and emerging injection and non-injection drug use trends driving HIV risk behaviors and transmission in some parts of the world. Recent Findings While HIV incidence has declined in many countries, HIV epidemics remain at troubling levels among key drug using populations including females who inject drugs (FWID), FWID who trade sex, sex partners of people who inject drugs (SP-PWID), young PWID, and people who use non-injection drugs in a number of low- and middle- income countries such as in Central Asia, Eastern Europe, Southeast Asia, and parts of Africa. Summary HIV epidemics occur within contexts of global economic and political forces, including poverty, human rights violations, discrimination, drug policies, trafficking, and other multi-level risk environments. Trends of injection and non-injection drug use and risk environments driving HIV epidemics in Central Asia, Eastern Europe, Southeast Asia, and parts of Africa call for political will to improve HIV and substance use service delivery, access to combination HIV prevention, and harm reduction programs.

Older driver training using video and global positioning system technology--a randomized controlled trial.

PubMed

Porter, Michelle M

2013-05-01

There is emerging evidence that older driver training programs with on-road instruction are more effective than driver education programs that are conducted only in the classroom. Although most programs have provided this additional in-vehicle training with a driving instructor and a dual-braked vehicle, technology could assist in providing this feedback. It was hypothesized that participants who received video and global positioning system (GPS) feedback (Video group) in addition to classroom education would improve to a greater extent than those who received a classroom-based course alone (Education) or Control participants. Fifty-four participants (32 men and 22 women), 70-89 years old, randomized to one of the three groups, completed the study. All participants underwent pre- and postintervention driving tests, in their own vehicle, on a standardized route, that were recorded with video and GPS equipment. The Video group met with a driving instructor to receive feedback on their driving errors in their preintervention driving test. A blinded assessor scored all driving tests in random order. The Video group significantly reduced their driving errors by 25% (p < .05) following the intervention, whereas the other two groups did not change significantly. Fifty-two percent of participants from the Video group improved their global safety rating, whereas only 5.3% in the Control and 22.2% in the Education groups did. This study suggests that direct driving feedback using video and GPS technology could be an effective and novel means to provide older driver education.

Chasing the silver bullet: measuring driver fatigue using simple and complex tasks.

Driver fatigue remains a significant cause of motor-vehicle accidents worldwide. New technologies are increasingly utilised to improve road safety, but there are no effective on-road measures for fatigue. While simulated driving tasks are sensitive, and simple performance tasks have been used in industrial fatigue management systems (FMS) to quantify risk, little is known about the relationship between such measures. Establishing a simple, on-road measure of fatigue, as a fitness-to-drive tool, is an important issue for road safety and accident prevention, particularly as many fatigue related accidents are preventable. This study aimed to measure fatigue-related performance decrements using a simple task (reaction time - RT) and a complex task (driving simulation), and to determine the potential for a link between such measures, thus improving FMS success. Fifteen volunteer participants (7 m, 8 f) aged 22-56 years (mean 33.6 years), underwent 26 h of supervised wakefulness before an 8h recovery sleep opportunity. Participants were tested using a 30-min interactive driving simulation test, bracketed by a 10-min psychomotor vigilance task (PVT) at 4, 8, 18 and 24h of wakefulness, and following recovery sleep. Extended wakefulness caused significant decrements in PVT and driving performance. Although these measures are clearly linked, our analyses suggest that driving simulation cannot be replaced by a simple PVT. Further research is needed to closely examine links between performance measures, and to facilitate accurate management of fitness to drive, which requires more complex assessments of performance than RT alone.

Experimental Observation of Nonlinear Mode Coupling In the Ablative Rayleigh-Taylor Instability on the NIF

NASA Astrophysics Data System (ADS)

Martinez, David

2015-11-01

We investigate on the National Ignition Facility (NIF) the ablative Rayleigh-Taylor (RT) instability in the transition from linear to highly nonlinear regimes. This work is part of the Discovery Science Program on NIF and of particular importance to indirect-drive inertial confinement fusion (ICF) where careful attention to the form of the rise to final peak drive is calculated to prevent the RT instability from shredding the ablator in-flight and leading to ablator mixing into the cold fuel. The growth of the ablative RT instability was investigated using a planar plastic foil with pre-imposed two-dimensional broadband modulations and diagnosed using x-ray radiography. The foil was accelerated for 12ns by the x-ray drive created in a gas-filled Au radiation cavity with a radiative temperature plateau at 175 eV. The dependence on initial conditions was investigated by systematically changing the modulation amplitude, ablator material and the modulation pattern. For each of these cases bubble mergers were observed and the nonlinear evolution of the RT instability showed insensitivity to the initial conditions. This experiment provides critical data needed to validate current theories on the ablative RT instability for indirect drive that relies on the ablative stabilization of short-scale modulations for ICF ignition. This paper will compare the experimental data to the current nonlinear theories.

Traffic accident is one of the severe social problems in the world, but the appraisal and prevention of the fatigue driving is still a difficult problem that can not be solved. This paper is to study the results of fatigue driving and the existing antifatigue driving products, collecting brain wave with the TGAM (ThinkGear AM) Brain Wave Sensor Chip. We analyze the collected waveform based on eye blink detect algorithm to work out current situation of the driver. According to the analysis results, Sound Module and controllable speed car will make a series of feedback. Finally, an effective Anti- Fatigue Driving System is designed based on all above.

Motor activity is often initiated by a population of command-like interneurons. Command-like interneurons that reliably drive programs have received the most attention, so little is known about how less reliable command-like interneurons may contribute to program generation. We study two electrically coupled interneurons, cerebral-buccal interneuron-2 (CBI-2) and CBI-11, which activate feeding motor programs in the mollusk Aplysia californica. Earlier work indicated that, in rested preparations, CBI-2, a powerful activator of programs, can trigger ingestive and egestive programs. CBI-2 reliably generated ingestive patterns only when it was repeatedly stimulated. The ability of CBI-2 to trigger motor activity has been attributed to the two program-promoting peptides it contains, FCAP and CP2. Here, we show that CBI-11 differs from CBI-2 in that it contains FCAP but not CP2. Furthermore, it is weak in its ability to drive programs. On its own, CBI-11 is therefore less effective as a program activator. When it is successful, however, CBI-11 is an effective specifier of motor activity; that is, it drives mostly ingestive programs. Importantly, we found that CBI-2 and CBI-11 complement each other's actions. First, prestimulation of CBI-2 enhanced the ability of CBI-11 to drive programs. This effect appears to be partly mediated by CP2. Second, coactivation of CBI-11 with CBI-2 makes CBI-2 programs immediately ingestive. This effect may be mediated by specific actions that CBI-11 exerts on pattern-generating interneurons. Therefore, different classes of command-like neurons in a motor network may make distinct, but potentially complementary, contributions as either activators or specifiers of motor activity.

The ability of CBI-2 to trigger motor activity has been attributed to the two program-promoting peptides it contains, FCAP and CP2. Here, we show that CBI-11 differs from CBI-2 in that it contains FCAP but not CP2. Furthermore, it is weak in its ability to drive programs. On its own, CBI-11 is therefore less effective as a program activator. When it is successful, however, CBI-11 is an effective specifier of motor activity; that is, it drives mostly ingestive programs. Importantly, we found that CBI-2 and CBI-11 complement each other's actions. First, prestimulation of CBI-2 enhanced the ability of CBI-11 to drive programs. This effect appears to be partly mediated by CP2. Second, coactivation of CBI-11 with CBI-2 makes CBI-2 programs immediately ingestive. This effect may be mediated by specific actions that CBI-11 exerts on pattern-generating interneurons. Therefore, different classes of command-like neurons in a motor network may make distinct, but potentially complementary, contributions as either activators or specifiers of motor activity.

Impact of providing drinkers with "know your limit" information on drinking and driving: a field experiment.

Johnson, Mark B; Clapp, John D

Given that most effective alcohol harm-reduction laws specify the blood alcohol concentration (BAC) that constitutes illegal behavior (e.g., the .08% breath alcohol concentration legal limit), interventions that allow drinkers to accurately estimate their BACs, and thus better assess their risk, have potential importance to long-term driving-under-the-influence prevention efforts. This study describes a field experiment designed to test the impact on drinking of providing "Know Your Limit" (KYL) BAC estimation cards to individuals in a natural drinking environment. We randomly sampled 1,215 U.S. residents as they entered Mexico for a night of drinking, interviewed them, and randomly assigned them to one of six experimental conditions. Participants were reinterviewed and breath-tested when they returned to the United States. The experimental conditions included providing generic warnings about drinking and driving, giving out gender-specific BAC calculator cards (KYL cards), and providing incentives to moderate their drinking. Cueing participants about the risks of drunk driving resulted in significantly lower BACs (relative to control) for participants who indicated that they would drive home. Providing KYL matrixes did not reduce BACs, and, in fact, some evidence suggests that KYL cards undermined the effect of the warning. KYL information does not appear to be an effective tool for reducing drinking and driving. Implications for prevention and future research are discussed.

Unintentional injury is a significant public health burden for American Indians and Alaska Natives and was the leading cause of death among those aged 1 to 44 years between 1999 and 2004. Of those deaths, motor vehicle-related deaths cause the most mortality, justifying the need for intervention at an American Indian Reservation in Arizona (United States). We describe motor vehicle injury prevention program operations from 2004 through 2013. This community-based approach led by a multidisciplinary team primarily comprised of environmental public health and law enforcement personnel implemented evidence-based strategies to reduce the impact of motor vehicle-related injuries and deaths, focusing on reducing impaired driving and increasing occupant restraint use. Strategies included: mass media campaigns to enhance awareness and outreach; high-visibility sobriety checkpoints; passing and enforcing 0.08% blood alcohol concentration limits for drivers and primary occupant restraint laws; and child car seat distribution and education. Routine monitoring and evaluation data showed a significant 5% to 7% annual reduction of motor vehicle crashes (MVCs), nighttime MVCs, MVCs with injuries/fatalities, and nighttime MVCs with injuries/fatalities between 2004 and 2013, but the annual percent change in arrests for driving under the influence (DUI) was not significant. There was also a 144% increase in driver/front seat passenger seat belt use, from 19% in 2011 before the primary occupant restraint law was enacted to 47% during the first full year of enforcement (2013). Car seat checkpoint data also suggested a 160% increase in car seat use, from less than 20% to 52% in 2013. Implementation of evidence-based strategies in injury prevention, along with employment of key program approaches such as strong partnership building, community engagement, and consistent staffing and funding, can narrow the public health disparity gap experienced among American Indian and Alaska Native communities.

Preventing AIDS in the developing world.

Horton, R

1993-06-12

The World Health Organization (WHO) was criticized at the 9th International Conference on AIDS in Berlin by an ACT UP spokesman for lacking a coordinated strategy against HIV and AIDS. ACT UP further called for the implementation of networks of effective treatment and care programs in lieu of continued pilot projects, and urged the World Bank to write off loans to nations most jeopardized by AIDS. Dr. Dean Jamison of the Bank discounted the viability of such loan forgiveness on the basis of equity. Funding should instead come from developing countries with the help of developed nations, the private sector, and international bodies. Declining age at first intercourse has led to half of all HIV infections worldwide occurring among individuals under age 25 years; HIV spread among the young is the main driving force behind the pandemic. Professor Peter Piot of WHO emphasized the importance of focusing efforts on women; paying attention to nongovernmental organizations as a group which receives 15% of WHO country funding; and taking issue with those who claim that no HIV/AIDS epidemic exists in Africa. Coordinated action taken to provide condoms, treat sexually transmitted diseases, and eradicate HIV could prevent up to 4 million infections in Africa, 4 million in Asia, and 1 million in Latin America. The director of the WHO's Global Program on AIDS, Dr. Michael Merson, asserted that half of all new HIV infections predicted for the developing world for the rest of the decade could be prevented if another $1.5-2.9 billion annually were invested in nations' HIV prevention strategies. These investments would save $90 billion in health costs and lost economic activity by the end of the century. Such an outlay is minuscule next to the $49 billion cost to Kuwait of the military Operation Desert Storm.

Vocal Problems in Sports and Fitness Instructors: A Study of Prevalence, Risk Factors, and Need for Prevention in France.

Sports and fitness instructors (SFIs) are known for being a high-risk population for voice difficulties (VD). However, past studies have encountered various methodological difficulties in determining prevalence and risk factors for VD in SFIs, such as limited population, gender and selection biases, or poor statistical power, because VD were studied as a binary variable. The present research work addresses these issues and aims at studying the prevalence of vocal problems and risk factors in French SFIs, a population in which no such study was conducted yet. Another objective is to survey the French SFIs' habits and expectations regarding vocal prevention and care. This is a cross-sectional study. Three hundred and twenty SFIs answered a questionnaire, whether in an online (n = 267) or a paper (n = 53) version. The questionnaire consisted of 31 items addressing self-reported vocal difficulties, supposed risk factors, and personal health-care history, followed by the Voice Handicap Index assessment. Prevalence of self-reported vocal difficulties is 55%. The Voice Handicap Index is significantly associated with gender, age, and variables related to work environment (noise and music) and habits (shouting, frequency of classes), as well as with daily sleeping time. Results also indicate that a minority of the SFIs (37%) received information on vocal difficulties, whereas a majority (80%) declares being interested in participating in prevention programs. This work confirms that SFIs are a high-risk population for VD, underlines the need for specific information programs in France, and provides relevant data for driving such preventive actions.

DriveID: safety innovation through individuation.

PubMed

Sawyer, Ben; Teo, Grace; Mouloua, Mustapha

2012-01-01

The driving task is highly complex and places considerable perceptual, physical and cognitive demands on the driver. As driving is fundamentally an information processing activity, distracted or impaired drivers have diminished safety margins compared with non- distracted drivers (Hancock and Parasuraman, 1992; TRB 1998 a & b). This competition for sensory and decision making capacities can lead to failures that cost lives. Some groups, teens and elderly drivers for example, have patterns of systematically poor perceptual, physical and cognitive performance while driving. Although there are technologies developed to aid these different drivers, these systems are often misused and underutilized. The DriveID project aims to design and develop a passive, automated face identification system capable of robustly identifying the driver of the vehicle, retrieve a stored profile, and intelligently prescribing specific accident prevention systems and driving environment customizations.

Problem This paper summarizes the findings on novice teenage driving outcomes (e.g., crashes and risky driving behaviors) from the Naturalistic Teenage Driving Study. Method Survey and driving data from a data acquisition system (Global Positioning System, accelerometers, cameras) were collected from 42 newly-licensed teenage drivers and their parents during the first 18 months of teenage licensure; stress responsivity was also measured in teenagers. Result Overall teenage crash and near crash (CNC) rates declined over time, but were >4 times higher among teenagers than adults. Contributing factors to teenage CNC rates included secondary task engagement (e.g., distraction), kinematic risky driving, low stress responsivity, and risky social norms. Conclusion The data support the contention that the high novice teenage CNC risk is due both to inexperience and risky driving behavior, particularly kinematic risky driving and secondary task engagement. Practical Applications Graduated driver licensing policy and other prevention efforts should focus on kinematic risky driving, secondary task engagement, and risky social norms. PMID:26403899

Background: Encouragement of stroke patients to resume driving is important to promote their reintegration into the community. Limited rehabilitation has been performed in this regard, owing to lack of specific knowledge on the part of medical staff. To establish an effective support program for stroke patients who wish to resume driving, we propose comprehensive training by medical staff using a driving simulator. Methods: A survey of stroke patients admitted to the Tokyo Metropolitan Rehabilitation Hospital was first performed. A questionnaire was sent to 525 patients. Of 218 responses, the answers of 118 patients who had been driving before their stroke were analyzed. More than 80% of stroke patients did not obtain enough information about resuming driving during their hospital stay, and 38.1% of patients would have liked to have had driving training with a simulator. From these results, we set out to determine the effect of driving training using a realistic and technically advanced driving simulator. Twenty-four stroke patients and 20 healthy controls were included in the study. Results: Repeat training with the simulator resulted in an increased ability to perform braking and an improvement in driving ability. The majority of stroke patients who had the mental and physical ability to drive a car were likely to be assessed as being able to resume driving as a result of the training program. Conclusion: This study indicates that comprehensive support by medical staff and provision of adequate information about resumption of driving and the opportunity for training on a driving simulator are likely to aid resumption of driving by stroke patients, thus enhancing their rehabilitation and social reintegration.

Graduated driver licensing programs and fatal crashes of 16-year-old drivers: a national evaluation.

PubMed

Chen, Li-Hui; Baker, Susan P; Li, Guohua

2006-07-01

Implementation of graduated driver licensing programs is associated with reductions in crash rates of young drivers, but graduated driver licensing programs vary in their components. The impact of programs with different components is unknown. The purpose of this work was to determine which graduated driver licensing programs are associated with the greatest reductions in fatal motor vehicle crashes involving 16-year-old drivers. We conducted a retrospective study of all 16-year-old drivers involved in fatal crashes in the United States from 1994 through 2004 using data from the Fatality Analysis Reporting System and the US Census Bureau. We measured incidence rate ratios of fatal motor vehicle crashes involving 16-year-old drivers according to graduated driver licensing programs, adjusted for state and year. Compared with state quarters with no graduated driver licensing program components, reductions of 16% to 21% in fatal crash involvement rates of 16-year-old drivers occurred with programs that included > or = 3-month mandatory waiting period, nighttime driving restriction, and either > or = 30 hours of supervised driving or passenger restriction. Reductions of 18% to 21% occurred in state quarters with programs that included > or = 5 of the 7 components examined. Drivers aged 20 to 24 or 25 to 29 years did not experience significant reductions. Comprehensive graduated driver licensing programs are associated with reductions of approximately 20% in 16-year-old drivers' fatal crash involvement rates. The greatest benefit seems to be associated with programs that include age requirements and > or = 3 months of waiting before the intermediate stage, nighttime driving restriction, and either > or = 30 hours of supervised driving or passenger restriction.

The role of personality traits and driving experience in self-reported risky driving behaviors and accident risk among Chinese drivers.

The purpose of this study was to explore the role of personality traits and driving experience in the prediction of risky driving behaviors and accident risk among Chinese population. A convenience sample of drivers (n=511; mean (SD) age=34.2 (8.8) years) completed a self-report questionnaire that was designed based on validated scales for measuring personality traits, risky driving behaviors and self-reported accident risk. Results from structural equation modeling analysis demonstrated that the data fit well with our theoretical model. While showing no direct effects on accident risk, personality traits had direct effects on risky driving behaviors, and yielded indirect effects on accident risk mediated by risky driving behaviors. Both driving experience and risky driving behaviors directly predicted accident risk and accounted for 15% of its variance. There was little gender difference in personality traits, risky driving behaviors and accident risk. The findings emphasized the importance of personality traits and driving experience in the understanding of risky driving behaviors and accident risk among Chinese drivers and provided new insight into the design of evidence-based driving education and accident prevention interventions.

Near-term hybrid vehicle program, phase 1. Appendix B: Design trade-off studies. [various hybrid/electric power train configurations and electrical and mechanical drive-line components

NASA Technical Reports Server (NTRS)

1979-01-01

The relative attractiveness of various hybrid/electric power train configurations and electrical and mechanical drive-line components was studied. The initial screening was concerned primarily with total vehicle weight and economic factors and identified the hybrid power train combinations which warranted detailed evaluation over various driving cycles. This was done using a second-by-second vehicle simulation program which permitted the calculations of fuel economy, electricity usage, and emissions as a function of distance traveled in urban and highway driving. Power train arrangement possibilities were examined in terms of their effect on vehicle handling, safety, serviceability, and passenger comfort. A dc electric drive system utilizing a separately excited motor with field control and battery switching was selected for the near term hybrid vehicle. Hybrid vehicle simulations showed that for the first 30 mi (the electric range of the vehicle) in urban driving, the fuel economy was 80 mpg using a gasoline engine and 100 mpg using a diesel engine. In urban driving the hybrid would save about 75% of the fuel used by the conventional vehicle and in combined urban/highway driving the fuel saving is about 50%.

Enforcement of alcohol-impaired driving laws is an important component of efforts to prevent alcohol-involved motor vehicle fatalities. Little is known about the use of drinking-driving enforcement strategies by state and local law enforcement agencies or whether the use of strategies differs by agency and jurisdiction characteristics. We conducted two national surveys, with state patrol agencies (n = 48) and with a sample of local law enforcement agencies (n = 1,082) selected according to state and jurisdiction population size. We examined 3 primary enforcement strategies (sobriety checkpoints, saturation patrols, and enforcement of open container laws) and tested whether use of these strategies differed by jurisdiction and agency characteristics across state and local law enforcement agencies Most state patrol agencies reported conducting sobriety checkpoints (72.9%) and saturation patrols (95.8%), whereas less than half (43.8%) reported enforcing open container laws. In contrast, a lower proportion of local law enforcement agencies reported using these alcohol-impaired driving enforcement strategies (41.5, 62.7, and 41.1%, respectively). Sobriety checkpoint enforcement was more common in states in the dry South region (vs. wet and moderate regions). Among local law enforcement agencies, agencies with a full-time alcohol enforcement officer and agencies located in areas where drinking-driving was perceived to be very common (vs. not/somewhat common) were more likely to conduct multiple types of impaired driving enforcement. Recommended enforcement strategies to detect and prevent alcohol-impaired driving are employed in some jurisdictions and underutilized in others. Future research should explore the relationship of enforcement with drinking and driving behavior and alcohol-involved motor vehicle fatalities.

A screw-released roller brake including an input drive assembly, an output drive assembly, a plurality of locking sprags, a mechanical tripper nut for unlocking the sprags, and a casing therefor. The sprags consist of three dimensional (3-D) sprag members having pairs of contact surface regions which engage respective pairs of contact surface regions included in angular grooves or slots formed in the casing and the output drive assembly. The sprags operate to lock the output drive assembly to the casing to prevent rotation thereof in an idle mode of operation. In a drive mode of operation, the tripper is either self actuated or motor driven and is translated linearly up and down against a spline and at the limit of its travel rotates the sprags which unlock while coupling the input drive assembly to the output drive assembly so as to impart a turning motion thereto in either a clockwise or counterclockwise direction.

Inferring the factors responsible for declines in abundance is a prerequisite to preventing the extinction of wild populations. Many of the policies and programmes intended to prevent extinctions operate on the assumption that the factors driving the decline of a population can be determined. Exogenous factors that cause declines in abundance can be statistically confounded with endogenous factors such as density dependence. To demonstrate the potential for confounding, we used an experiment where replicated populations were driven to extinction by gradually manipulating habitat quality. In many of the replicated populations, habitat quality and density dependence were confounded, which obscured causal inference. Our results show that confounding is likely to occur when the exogenous factors that are driving the decline change gradually over time. Our study has direct implications for wild populations, because many factors that could drive a population to extinction change gradually through time. © 2016 John Wiley & Sons Ltd/CNRS.

Moving computation closer to the data location has been a much theorized improvement to computation for decades. The increase in processor performance, the decrease in processor size and power requirement combined with the increase in data intensive computing has created a push to move computation as close to data as possible. We will show the next logical step in this evolution in computing: moving computation directly to storage. Hypothetical systems, known as Active Drives, have been proposed as early as 1998. These Active Drives would have a general-purpose CPU on each disk allowing for computations to be performed on them without the need to transfer the data to the computer over the system bus or via a network. We will utilize Seagate's Active Drives to perform general purpose parallel computing using the MapReduce programming model directly on each drive. We will detail how the MapReduce programming model can be adapted to the Active Drive compute model to perform general purpose computing with comparable results to traditional MapReduce computations performed via Hadoop. We will show how an Active Drive based approach significantly reduces the amount of data leaving the drive when performing several common algorithms: subsetting and gridding. We will show that an Active Drive based design significantly improves data transfer speeds into and out of drives compared to Hadoop's HDFS while at the same time keeping comparable compute speeds as Hadoop.

Much of this progress is attributable to strengthening laws against impaired driving along with vigorous enforcement efforts aimed at deterring impaired driving. In addition, many useful strategies can also be applied that focus on the control of alcohol availability, use, and promotion. Alcohol policies include controls on the price of alcohol, the location, density, and opening hours of sales outlets, controls on the social availability of alcohol, and on the promotion and advertising of alcohol. Enforcement of these policies is an important aspect of their effectiveness. These strategies have been shown to be effective or promising in reducing impaired driving as well as other consequences related to alcohol use and misuse.

Texting while driving has emerged as a significant distracted driving behavior among teenage drivers. A unique hospital-school collaborative pilot intervention (called "Be in the Zone" or "BITZ") was implemented to combat this growing problem. This intervention was hypothesized to lead to a decline in texting while driving among high school students. This collaborative intervention consisted of two separate phases. In Phase 1, small groups of high school student leaders participated in a half-day interactive educational session in a pediatric hospital. Pre- and post-follow-up surveys were administered to this group. In Phase 2, these same students took the lessons they learned from the hospital to plan and implement a yearlong peer-to-peer campaign that focused on a clear "no texting while driving" message at their schools. Two unannounced driver observations were conducted to evaluate the effectiveness of the pilot program. Sixty-one high school students participated in Phase 1. Self-reported texting while driving rates decreased significantly among the participants after Phase 1. Two schools were recruited to participate in Phase 2. Unannounced driver observations were conducted before the campaign and toward the end of the campaign. Postintervention, there was a significant decrease in the percentage of drivers who texted while driving. Preliminary results from this pilot program suggest that a strategy of combining hospital-school partnerships with a peer-driven educational approach can be effective in reducing texting while driving among teenagers in the short-term.

Much of the cancer burden in the USA is preventable, through application of existing knowledge. State-level funders and public health practitioners are in ideal positions to affect programs and policies related to cancer control. Mis-implementation refers to ending effective programs and policies prematurely or continuing ineffective ones. Greater attention to mis-implementation should lead to use of effective interventions and more efficient expenditure of resources, which in the long term, will lead to more positive cancer outcomes. This is a three-phase study that takes a comprehensive approach, leading to the elucidation of tactics for addressing mis-implementation. Phase 1: We assess the extent to which mis-implementation is occurring among state cancer control programs in public health. This initial phase will involve a survey of 800 practitioners representing all states. The programs represented will span the full continuum of cancer control, from primary prevention to survivorship. Phase 2: Using data from phase 1 to identify organizations in which mis-implementation is particularly high or low, the team will conduct eight comparative case studies to get a richer understanding of mis-implementation and to understand contextual differences. These case studies will highlight lessons learned about mis-implementation and identify hypothesized drivers. Phase 3: Agent-based modeling will be used to identify dynamic interactions between individual capacity, organizational capacity, use of evidence, funding, and external factors driving mis-implementation. The team will then translate and disseminate findings from phases 1 to 3 to practitioners and practice-related stakeholders to support the reduction of mis-implementation. This study is innovative and significant because it will (1) be the first to refine and further develop reliable and valid measures of mis-implementation of public health programs; (2) bring together a strong, transdisciplinary team with significant expertise in practice-based research; (3) use agent-based modeling to address cancer control implementation; and (4) use a participatory, evidence-based, stakeholder-driven approach that will identify key leverage points for addressing mis-implementation among state public health programs. This research is expected to provide replicable computational simulation models that can identify leverage points and public health system dynamics to reduce mis-implementation in cancer control and may be of interest to other health areas.

The promise and peril of CRISPR gene drives: Genetic variation and inbreeding may impede the propagation of gene drives based on the CRISPR genome editing technology.

PubMed

Zentner, Gabriel E; Wade, Michael J

2017-10-01

Gene drives are selfish genetic elements that use a variety of mechanisms to ensure they are transmitted to subsequent generations at greater than expected frequencies. Synthetic gene drives based on the clustered regularly interspersed palindromic repeats (CRISPR) genome editing system have been proposed as a way to alter the genetic characteristics of natural populations of organisms relevant to the goals of public health, conservation, and agriculture. Here, we review the principles and potential applications of CRISPR drives, as well as means proposed to prevent their uncontrolled spread. We also focus on recent work suggesting that factors such as natural genetic variation and inbreeding may represent substantial impediments to the propagation of CRISPR drives. © 2017 WILEY Periodicals, Inc.

Prior research has shown that designated drivers (DD) are widely used as a preventive measure for driving under the influence. Despite the prevalence of alcohol involvement in boating accidents, much less is known about the use of a designated boat operator (DBO). The current study investigated the prevalence of DBO use in recreational boating and compared the characteristics of DD users and DBO users. Several survey questionnaires were distributed to a group of undergraduate students at a large southwestern university for the purpose of investigating demographic characteristics, alcohol-use pattern, and other alcohol-related problem behaviors, such as driving and boating under the influence. Approximately 45% of the boaters reported they had drunk alcohol while boating, and approximately 70% had used a DBO in the most recent boating event. The DBO users were found to be similar to the DD users in terms of drinking pattern, age of drinking onset, and driving behaviors. High rates of alcohol use in recreational boating suggest the need for prevention strategies. Furthermore, future studies are needed to investigate the selection process of the DBOs and the differences between passengers and boat operators, which could shed light on strategies to prevent alcohol- involved boating injuries.

The relationship between impaired driving crashes and beliefs about impaired driving: do residents in high crash rate counties have greater concerns about impaired driving?

PubMed

Beck, Kenneth H; Yan, Alice F; Wang, Min Qi; Kerns, Timothy J; Burch, Cynthia A

2009-04-01

The purpose of this investigation was to examine the relationship between impaired driving crashes and public beliefs and concerns about impaired driving across each of Maryland's twenty-four counties (including Baltimore City). It was hypothesized that residents of counties that experience higher impaired driving crashes would express more concerns about impaired driving and perceive more risks about driving impaired than residents of counties that have lower rates of impaired driving. Data for alcohol impaired driving crashes were obtained for the years 2004-2006. These data were compared to public opinion data that was obtained annually by random-digit-dial telephone surveys from 2004 to 2007. Concerns about drunk driving as well as perceptions of the likelihood of being stopped by the police if one were to drive after having too much to drink were related to counties with higher serious impaired driving crash rates, as were perceptions that the police and the legal system were too lenient. Perceptions about the likelihood of being stopped by the police were higher in those counties with more impaired driving enforcement activity. Perceptions of concern appear to be shaped more by crash exposure than enforcement activity. Campaigns that address impaired driving prevention should substantially increase enforcement, strengthen the adjudication process of impaired drivers, and emphasize the potential seriousness of drinking-driving crashes in their promotional activities.

Personal and contextual factors in the escalation of driving after drinking across the college years.

PubMed

Quinn, Patrick D; Fromme, Kim

2012-12-01

College students continue to drive after drinking at alarmingly high rates. Age trends suggest that driving after drinking increases from late adolescence across the college years, largely mirroring trends in binge drinking. Relatively little research, however, has examined change over time in driving after drinking among college students or tested whether some students might be at greater risk of escalations in driving after drinking. Using a sample of 1,833 nonabstaining students who completed surveys for seven semesters across the college years, we tested whether personal (i.e., age of drinking onset, gender, risk perceptions, and sensation seeking) and contextual (i.e., college residence) factors were associated with changes in driving after drinking. Using latent growth curve modeling, we found significant individual differences in rates of change in driving after drinking. Male students and students who began drinking earlier in life increased in driving after drinking more rapidly, whereas living in on-campus housing was associated with time-specific decreases in driving after drinking. These results demonstrate the value of considering driving after drinking from a longitudinal perspective and suggest possible avenues toward preventing the public health consequences of intoxicated driving. 2013 APA, all rights reserved

Rothschild, Michael L; Mastin, Beth; Miller, Thomas W

2006-11-01

Over the past decade there has been little decrease in the number of alcohol-related driving fatalities. During this time most interventions have been educational or legal. This paper presents the results of a field experiment that used social marketing to introduce a new ride program into three rural communities. Almost all people in the 21-34-year-old target know that they should not drive while impaired, and most agree it is not a good thing to do, but for many the opportunity to behave properly does not exist. The Road Crew program was developed using new product development techniques and implemented by developing broad coalitions within the communities. A key feature of the program included rides to, between, and home from bars in older luxury vehicles. Results showed a significant shift in riding/driving behavior, especially among 21-34-year olds, a projected 17% decline in alcohol-related crashes in the first year, no increase in drinking behavior, and large savings between the reactive cost of cleaning up after a crash and the proactive cost of avoiding a crash. Programs have become self-sustaining based on fares and tavern contributions, and have become part of the life style in the treatment communities.

The secretary's Conference for Youth on Drinking and Driving: special report.

Callen, K

1983-01-01

Part of a Department of Health and Human Services initiative against teenage alcohol abuse, a national Conference for Youth on Drinking and Driving--held March 26-28, 1983 in Chevy Chase, Md. --brought together more than 300 high school student delegates and school superintendents from every State and Territory. The conference spotlighted successful programs that students around the country have undertaken to promote sober driving--programs that incorporate these key principles: (a) they rely almost solely on peer leadership "by students for students"; (b) they employ a "holistic" approach to health promotion, emphasizing self-esteem and alternatives to alcohol and drug abuse; and (c) they use the resources of the whole community. Working with student leaders of these model programs, conference delegates devised ways to launch similar programs in their own schools and communities and to enlist help from parents, teachers, lawmakers, the media, and business and civic groups. The Department of Health and Human Services plans to hold similar conferences annually, to mobilize future generations of students against drunk driving.

The objective of this study was to identify the prevalence and potential risk factors of farm vehicle-related road traffic crashes among farm vehicle drivers in southern China. A cross-sectional study was used to interview 1,422 farm vehicle drivers in southern China. Farm vehicle-related road traffic crashes that occurred from December 2013 to November 2014 were investigated. Data on farm vehicle-related road traffic crashes and related factors were collected by face-to-face interviews. The prevalence of farm vehicle-related road traffic crashes among the investigated drivers was 7.2%. Farm vehicle-related road traffic crashes were significantly associated with self-reported vision problem (adjusted odds ratio [AOR] = 6.48, 95% confidence interval [CI], 3.86-10.87), self-reported sleep disorders (AOR = 10.03, 95% CI, 6.28-15.99), self-reported stress (AOR = 20.47, 95% CI, 9.96-42.08), reported history of crashes (AOR = 5.40, 95% CI, 3.47-8.42), reported history of drunk driving (AOR = 5.07, 95% CI, 2.97-8.65), and reported history of fatigued driving (AOR = 5.72, 95% CI, 3.73-8.78). The number of road traffic crashes was highest in the daytime and during harvest season. In over 96% of farm vehicle-related road traffic crashes, drivers were believed to be responsible for the crash. Major crash-causing factors included improper driving, careless driving, violating of traffic signals or signs, and being in the wrong lane. Findings of this study suggest that farm vehicle-related road traffic crashes have become a burgeoning public health problem in China. Programs need to be developed to prevent farm vehicle-related road traffic crashes in this emerging country.

Driving self-regulation and ride service utilization in a multicommunity, multistate sample of U.S. older adults.

This study examined a multicommunity alternative transportation program available 24 hours a day, 7 days a week, for any purpose, offering door-through-door service in private automobiles to members who either do not drive or are transitioning away from driving. Specific aims were to describe the characteristics of members by driving status and ride service usage of these members. Data came from administrative records maintained by a nonprofit ride service program and include 2,661 individuals aged 65+ residing in 14 states who joined the program between April 1, 2010, and November 8, 2013. Latent class analysis was used to group current drivers into 3 classes of driving status of low, medium, and high self-regulation, based on their self-reported avoidance of certain driving situations and weekly driving frequency. Demographics and ride service use rate for rides taken through March 31, 2014, by type of ride (e.g., medical, social, etc.) were calculated for nondrivers and drivers in each driving status class. The majority of ride service users were female (77%) and aged 65-74 years (82%). The primary method of getting around when enrolling for the transportation service was by riding with a friend or family member (60%). Among the 67,883 rides given, nondrivers took the majority (69%) of rides. Medical rides were the most common, accounting for 40% of all rides. Reported ride usage suggests that older adults are willing to use such ride services for a variety of trips when these services are not limited to specific types (e.g., medical). Further research can help tailor strategies to encourage both nondrivers and drivers to make better use of alternative transportation that meets the special needs of older people.

Disruption of Fetal Hormonal Programming (Prenatal Stress) Implicates Shared Risk for Sex Differences in Depression and Cardiovascular Disease

PubMed Central

Goldstein, JM; Handa, RJ; Tobet, SA

2014-01-01

Comorbidity of major depressive disorder (MDD) and cardiovascular disease (CVD) represents the fourth leading cause of morbidity and mortality worldwide, and women have a two times greater risk than men. Thus understanding the pathophysiology has widespread implications for attenuation and prevention of disease burden. We suggest that sex-dependent MDD-CVD comorbidity may result from alterations in fetal programming consequent to the prenatal maternal environments that produce excess glucocorticoids, which then drive sex-dependent developmental alterations of the fetal hypothalamic-pituitary-adrenal (HPA) axis circuitry impacting mood, stress regulation, autonomic nervous system (ANS), and the vasculature in adulthood. Evidence is consistent with the hypothesis that disruptions of pathways associated with gamma aminobutyric acid (GABA) in neuronal and vascular development and growth factors have critical roles in key developmental periods and adult responses to injury in heart and brain. Understanding the potential fetal origins of these sex differences will contribute to development of novel sex-dependent therapeutics. PMID:24355523

Distracted driving caused by cellphone use is a significant source of needless injuries. These injuries place unnecessary financial burden, emotional stress and health care resource misuse on society. This paper states the Canadian Association of Emergency Physician's (CAEP's) position on cellphone use while driving. In recent years, numerous studies were conducted on the danger of cellphone use while driving. Research has shown that cellphone use while driving negatively impacts cognitive functions, visual fields, reaction time and overall driving performances. Some studies found that cellphone use is as dangerous as driving under the influence of alcohol. Moreover, vehicle crash rates were shown to be significantly higher when drivers used cellphones. Countermeasures have been implemented in recent years. Over 50 countries worldwide have laws limiting the use of cellphones while driving. Six Canadian provinces, Newfoundland and Labrador, Nova Scotia, Quebec, Ontario, British Columbia and Saskatchewan, currently have legislation prohibiting cellphone use. Other provinces are considering implementing similar bans. As emergency physicians, we must advocate for injury prevention. Cell phone related road traumas are avoidable. CAEP supports all measures to ban cellphone use while driving.

Driving Cessation Anno 2010: Which Older Drivers Give Up Their License and Why? Evidence From Denmark.

PubMed

Siren, Anu; Haustein, Sonja

2016-01-01

This study focuses on the decision to either stop or continue driving among a cohort of Danish seniors whose driving licenses expire, for the first time, at the age of 70. Based on 1,537 standardized telephone interviews with licensed drivers, we compared persons who intended to renew or not to renew their licenses. The results partly recapture the findings of earlier studies. However, in contrast to former cohorts, a much higher percentage of older drivers intended to keep their licenses. The strongest factors predicting the intention to renew were active car use, feeling safe as a driver, and not having illnesses that impaired driving ability. Three of these factors were strongly correlated with gender, indicating that efforts to prevent premature driving cessation should especially focus on increasing women's confidence and experience in driving. © The Author(s) 2014.

New Driving Scheme to Improve Hysteresis Characteristics of Organic Thin Film Transistor-Driven Active-Matrix Organic Light Emitting Diode Display

2011-02-01

A new driving scheme for an active-matrix organic light emitting diode (AMOLED) display was developed to prevent the picture quality degradation caused by the hysteresis characteristics of organic thin film transistors (OTFTs). In this driving scheme, the gate electrode voltage of a driving-OTFT is directly controlled through the storage capacitor so that the operating point for the driving-OTFT is on the same hysteresis curve for every pixel after signal data are stored in the storage capacitor. Although the number of OTFTs in each pixel for the AMOLED display is restricted because OTFT size should be large enough to drive organic light emitting diodes (OLEDs) due to their small carrier mobility, it can improve the picture quality for an OTFT-driven flexible OLED display with the basic two transistor-one capacitor circuitry.

Mindfulness predicts less texting while driving among young adults: Examining attention- and emotion-regulation motives as potential mediators

Feldman, Greg; Greeson, Jeff; Renna, Megan; Robbins-Monteith, Kendra

2011-01-01

Many young adult drivers read and send text messages while driving despite clear safety risks. Understanding predictors of texting-while-driving may help to indentify relevant targets for interventions to reduce this dangerous behavior. The present study examined whether individual differences in mindfulness is associated with texting-while-driving in a sample of young-adult drivers. Using path analysis, we tested whether this relationship would be mediated by the degree to which individuals use text-messaging as a means of reducing unpleasant emotions (emotion-regulation motives) and the degree to which individuals limit texting in order to focus on present-moment experiences (attention-regulation motives). Individuals lower in mindfulness reported more frequent texting-while-driving and this relationship appeared to be mediated primarily by emotion-regulation motives. Results may help inform the development of mindfulness-based interventions to prevent texting-while-driving. PMID:22031789

Improving the driving practices of pizza deliverers: Response generalization and moderating effects of driving history

PubMed Central

Ludwig, Timothy D.; Geller, E. Scott

1991-01-01

A practical intervention program, targeting the safety belt use of pizza deliverers at two stores, increased significantly the use of both safety belts (143% above baseline) and turn signals (25% above baseline). Control subjects (i.e., pizza deliverers at a third no-intervention store and patrons driving to the pizza stores) showed no changes in belt or turn signal use over the course of 7-month study. The intervention program was staggered across two pizza stores and consisted of a group meeting wherein employees discussed the value of safety belts, received feedback regarding their low safety belt use, offered suggestions for increasing their belt use, and made a personal commitment to buckle up by signing buckle-up promise cards. Subsequently, employee-designed buckle-up reminder signs were placed in the pizza stores. By linking license plate numbers to individual driving records, we examined certain aspects of driving history as moderators of pre- and postintervention belt use. Although baseline belt use was significantly lower for drivers with one or more driving demerits or accidents in the previous 5 years, after the intervention these risk groups increased their belt use significantly and at the same rate as drivers with no demerits or accidents. Whereas baseline belt use was similar for younger (under 25) and older (25 or older) drivers, younger drivers were markedly more influenced by the intervention than were older drivers. Individual variation in belt use during baseline, intervention, and follow-up phases indicated that some drivers require more effective and costly intervention programs to motivate their safe driving practices.

The drink driving situation in Colombia.

PubMed

Castaño, Ramón

2012-01-01

To describe and analyze the drink driving situation in Colombia. The assessment was based on semistructured interviews of key stakeholders and analysis of secondary data. Road traffic crashes caused 5704 deaths and injured 39,318 people in 2010. The 3 main sources of crash data-forensic authorities, traffic authorities, and motor vehicle insurance agencies-provide different information about crashes, drivers, and victims, but they cannot be routinely merged. This together with the problem of identifying alcohol as the cause of a crash makes it difficult to estimate the role of drink driving in road crashes. In addition, reliable figures for the incidence of drink driving are not available from the random breath test programs because of sampling issues, underreporting, and missing data on negative results. However, it can be argued that alcohol plays a role in fatalities, because the proportion of crashes involving fatalities rises on weekends and between 12:00 a.m. and 05:59 a.m. when drink driving is likely to occur. Colombia has strict drink-drive laws that specify 3 levels of offense and sanctions (level I: 40- 99 mg/100 mL, level II: 100-149 mg/100 mL, and level III: 150 mg/100 mL or above). Drivers responsible for causing crashes with fatalities and injuries can be imprisoned under criminal law and sentences are increased by 50 to 100 percent if they test positive for alcohol. Enforcement includes random breath testing for alcohol, but its impact is weakened by the lack of a legal requirement to submit to a test and poor implementation of sanctions. There have been mass media campaigns against drink driving including one linked to a major enforcement initiative in 2008. However, there was a consensus that most campaigns were not focused sufficiently on increasing drivers' perceived risk of being caught. According to those interviewed, campaigns aimed at responsible consumption and the use of designated drivers appear to have had a growing positive effect, but these impacts have not been empirically assessed. The Road Prevention Fund is a Sui Generis institution in Colombia that has played a key role in tackling the drink driving problem. Legal blood alcohol concentration (BAC) limits are on a par with international standards and the traffic authorities carry out regular roadside sobriety checks. However, the enforcement is weakened by poor implementation of sanctions. In addition, issues with data mean that the nature and extent of drink driving in Colombia cannot be accurately monitored.

Assessing factors causing severe injuries in crashes of high-deck buses in long-distance driving on freeways.

PubMed

Chu, Hsing-Chung

2014-01-01

High-deck buses that have a higher center of gravity traveling at an excessive speed have a higher likelihood of causing serious and fatal accidents when drivers lose control of the vehicle. In addition, drivers who suffer from fatigue in long-distance driving increase the likelihood of serious accident. This paper examines the effects of risk factors contributing to severe crashes associated with high-deck buses used for long-distance driving on freeways. An ordered logit and latent class models are used to examine significant factors on the severity of injuries in crashes related to high-deck buses. Driver fatigue, drivers or passengers not wearing a seat belt, reckless driving, drunk driving, crashes occurred between midnight and dawn, and crashes occurred at interchange ramps were found to significantly affect the severity of injuries in crashes involving high-deck buses. Safety policies to prevent severe injuries in crashes involving high deck buses used for long-distance runs on freeways include: (1) restricting drivers from exceeding the limit of daily driving hours and mandating sufficient rest breaks; (2) installing an automatic sleep-warning device in the vehicle; (3) drivers with obstructive sleep apnea syndrome or sleep disorders should be tested and treated before they are allowed to perform long hours of driving tasks; (4) educating the public or even amending the seatbelt legislation to require all passengers to wear a seat belt and thus reduce the chance of ejection from a high-deck bus and prevent serious injuries in a crash while traveling at a higher speed on freeways.

2015-01-01

The combined-use of alcohol and energy drinks is an emerging public health issue. This investigation examined differences in drinking and driving behaviors among combined-users (CU) and participants who consumed alcohol-only (AO). This study was specifically designed to investigate potential differences in drinker's perceptions of (a) what it means to them to drive over the .08 Blood Alcohol Content (BAC) driving limit and (b) what it means to drive after knowing they have had too much to drink to drive safely. College students (N = 355) were surveyed to assess differences in drinking and driving-related behaviors between the AO (n = 174) and CU (n = 107) groups. CU were more likely than AO to drive over the .08 BAC driving limit (53% vs. 38%; p = .009) and after knowing they were too drunk to drive (57% vs. 44%; p = .025). CU were also more likely (56% vs. 35%; p = .000) to ride with an intoxicated driver while knowing it was unsafe. Conclusions/Importance: Combined-users are more likely to drive after drinking, drive while knowingly drunk, and participate in other high-risk behaviors such as heavy drinking that increase the potential for injury. Public policy makers and health professionals should focus prevention efforts to reduce high-risk combined-use behavior.

The main purposes of this study were to examine the usefulness of the variables of the theory of planned behavior (viz. attitudes, social norms, and self-efficacy) and to explore the relationship between optimism bias and drink driving in young adults. In addition, we explored gender differences in drink driving with provision for the effect of variables such as driving frequency and alcohol consumption. Data were collected via a questionnaire administered to 274 drivers (59.9% females) aged 18-30 years (24.36 ± 2.96). The results obtained with provision for driving frequency revealed substantial differences in driving behaviors between genders. Thus, males were more prone to drink driving, perceived less disapproval by their significant others (parents and peers), and felt less able to avoid drinking-and-driving situations. In addition, they self-reported more frequent alcohol consumption and driving under the influence. The results also confirm the significance of peers' subjective norms and attitudes to drink driving in males. Overconfidence in their own driving skills for driving drunk and perceived behavioral control were found to be significant predictors for drink driving in females. Optimism bias also played a slightly significant role in predicting drink driving but only in females. The important practical implications of these results with a view to designing effective interventions to prevent the risks associated with drink driving in the young population are discussed. Interventions should focus on young people's perceptions of group norms and promoting cautionary driving choices and alternatives to drink driving.

Tremendous resources are spent each year developing programs and messages targeting adolescent risk behavior. Adolescents are often reasonably well educated about methods for health promotion such as preventing HIV infection, yet they fail to act accordingly. One widely used individual difference variable, sensation-seeking, has been incorporated in health message design to some extent, but it fails to take development into account. Research on adolescent egocentrism suggests adolescents experience personal fable which can lead to an exaggerated sense of invulnerability. The present study sampled adolescents and college students to examine relative contributions of egocentrism and sensation-seeking to risk-taking behavior. Results indicate a latent factor labeled risk-seeking (primarily indicated by disinhibition and risk-taking personality, and to a lesser degree by invulnerability, experience-seeking, boredom susceptibility, and thrill and adventure-seeking) indeed predicted a latent factor labeled delinquent behavior (primarily indicated by alcohol consumption and delinquency, and to a lesser degree by drug use, drinking and driving, and risky driving). Other results indicate consistently high personal fable combined with high sensation-seeking explained most risk-taking behavior. Implications and directions for future research are discussed.

Impact of anthropogenic and natural environmental changes on Echinococcus transmission in Ningxia Hui Autonomous Region, the People’s Republic of China

PubMed Central

2012-01-01

Echinococcus transmission is known to be affected by various environmental factors, which may be modified by human influence or natural events including global warming. Considerable population growth in the last fifty years in Ningxia Hui Autonomous Region (NHAR), the People’s Republic of China (PRC), has led to dramatic increases in deforestation and modified agricultural practices. In turn, this has resulted in many changes in the habitats for the definitive and intermediate hosts of both Echinococcus granulosus and E. multilocularis, which have increased the risks for transmission of both parasites, affecting echinococcosis prevalence and human disease. Ecological environmental changes due to anthropogenic activities and natural events drive Echinococcus transmission and NHAR provides a notable example illustrating how human activity can impact on a parasitic infection of major public health significance. It is very important to continually monitor these environmental (including climatic) factors that drive the distribution of Echinococcus spp. and their impact on transmission to humans because such information is necessary to formulate reliable future public health policy for echinococcosis control programs and to prevent disease spread.

2008-06-09

Long duration of driving is a significant cause of fatigue-related accidents on motorways or major roadways. The fatigue caused by driving for extended periods acutely impairs driver alertness and performance and can compromise transportation safety. This study quantitatively measured the progression of driver fatigue and identified the conservative safe duration of continuous highway driving. Thirty young male subjects were analyzed during 90 min of laboratory-simulated highway driving. Sleepiness ratings (SSS) and reaction time (RT) tests were used to assess impairment of driver alertness and vigilance. Additionally, various measures of driving performance recorded throughout the experiment were used to measure temporal deterioration of driver performance from alert to fatigued using principal component analysis (PCA). The analytical results revealed that SSS scores, reaction times (RTs) and unstable driving performance significantly increased over time, indicating that excessive driving time is a significant fatigue factor and potential cause of fatigue-related accidents. Moreover, the analytical results indicated that 80 min was the safe limit for monotonous highway driving. Based on the experimental findings of this study, public awareness of the adverse affects of driver fatigue during long-distance driving should be enhanced. This study provides explicit information of fatigue development that can be used to prevent fatigue-related accidents.

Vehicle Dynamics Control of In-wheel Electric Motor Drive Vehicles Based on Averaging of Tire Force Usage

NASA Astrophysics Data System (ADS)

Masaki, Nobuo; Iwano, Haruo; Kamada, Takayoshi; Nagai, Masao

For in-wheel electric motor drive vehicles, a new vehicle dynamics control which is based on the tire force usage rate is proposed. The new controller adopts non-linear optimal control could manage the interference between direct yaw-moment control and the tire force usage rate. The new control is considered total longitudinal and transverse tire force. Therefore the controller can prevent tire force saturation near tire force limit during cornering. Simulations and test runs by the custom made four wheel drive in-wheel motor electric vehicle show that higher driving stability performance compared to the performance of the same vehicle without control.

A simple method to prevent hard X-ray-induced preheating effects inside the cone tip in indirect-drive fast ignition implosions

DOE Office of Scientific and Technical Information (OSTI.GOV)

Liu, Dongxiao; Shan, Lianqiang; Zhou, Weimin

During fast-ignition implosions, preheating of inside the cone tip caused by hard X-rays can strongly affect the generation and transport of hot electrons in the cone. Although indirect-drive implosions have a higher implosion symmetry, they cause stronger preheating effects than direct-drive implosions. To control the preheating of the cone tip, we propose the use of indirect-drive fast-ignition targets with thicker tips. Experiments carried out at the ShenGuang-III prototype laser facility confirmed that thicker tips are effective for controlling preheating. Moreover, these results were consistent with those of 1D radiation hydrodynamic simulations.

Methods: Parent-teen dyads (n = 452) were recruited when teens received learner's permits and interviewed over the telephone at baseline, licensure, and three months post-licensure. After baseline, families were randomized to either the intervention group that received persuasive communications or to the comparison group that received general information about driving safety. Results: Both parents and teens in the intervention group reported significantly greater limits on teen driving at licensure and three months post-licensure. In multivariate analyses, intervention and baseline driving expectations had significant effects on driving limits at licensure. Intervention and driving limits established at licensure were associated with three month driving limits. Conclusion: The findings indicate that exposure to the Checkpoints Program increased parental limits on teen driving. PMID:12221027

Brazil lacks information about driving under the influence of alcohol (DUI) originated from representative samples obtained from the general population. 333 subjects with a valid driver's license and drinking in the last 12 months were drawn from a multistaged sample of 2,346 adults from the first Brazilian Household Survey of Patterns of Alcohol Use. A multivariate analysis was conducted to understand the associations between risk factors and driving after drinking three or more drinks. the overall DUI prevalence reported in the sample was 34.7% - 42.5% among males and 9.2% among females. Being male (OR = 6.0, 95% CI 2.9-12.6), having a previous DUI accident (OR = 7.9, 95% CI 2.5-24.9), binging in the last year (OR = 2.2, 95% CI 1.03-4.5) and having an unfavorable opinion towards policies (OR = 2.9, 95% CI 1.4-6.2) remained associated with heavy drinking and driving after model adjustments. This was the first study evaluating driving under the influence of alcohol in a representative sample of the Brazilian population. The prevalence of DUI found is alarming, and possibly underestimated in the sample. Results demonstrate the need for more studies on this association and show directions towards preventive strategies for the specific high-risk group of male drivers with previous problems with alcohol and unfavorable opinions about prevention policies.

Neurologically impaired persons seem to benefit from driving-training programs, but there is no convincing evidence to support this notion. The authors therefore investigated the effect of simulator-based training on driving after stroke. Eighty-three first-ever subacute stroke patients entered a 5-week 15-hour training program in which they were randomly allocated to either an experimental (simulator-based training) or control (driving-related cognitive tasks) group. Performance in off-road evaluations and an on-road test were used to assess the driving ability of subjects pre- and post-training. Outcome of an official predriving assessment administered 6 to 9 months poststroke was also considered. Both groups significantly improved in a visual and many neuropsychological evaluations and in the on-road test after training. There were no significant differences between both groups in improvements from pre- to post-training except in the "road sign recognition test" in which the experimental subjects improved more. Significant improvements in the three-class decision ("fit to drive," "temporarily unfit to drive," and "unfit to drive") were found in favor of the experimental group post-training. Academic qualification and overall disability together determined subjects that benefited most from the simulator-based driving training. Significantly more experimental subjects (73%) than control subjects (42%) passed the follow-up official predriving assessment and were legally allowed to resume driving. Simulator-based driving training improved driving ability, especially for well educated and less disabled stroke patients. However, the findings of the study may have been modified as a result of the large number of dropouts and the possibility of some neurologic recovery unrelated to training.

A program for the development and verification of drive-train dynamic technology is described along with its basis and the results expected from it. A central feature of this program is a drive-train test facility designed for the testing and development of advanced drive-train components, including shaft systems, dampers, and couplings. Previous efforts in designing flexible dynamic drive-train systems are reviewed, and the present state of the art is briefly summarized. The design of the test facility is discussed with major attention given to the formulation of the test-rig concept, dynamic scaling of model shafts, and the specification of design parameters. Specific efforts envisioned for the test facility are briefly noted, including evaluations of supercritical test shafts, stability thresholds for various sources and types of instabilities that can exist in shaft systems, effects of structural flexibility on the dynamic performance of dampers, and methods for vibration control in two-level and three-level flexible shaft systems.

The influence of parental and peer drinking behaviors on underage drinking and driving by young men.

PubMed

Zhang, Lening; Wieczorek, William F; Welte, John W

2012-01-01

Studies have consistently found that parental and peer drinking behaviors significantly influence adolescent drinking behavior and that adolescent drinking has a significant effect on their drinking-and-driving behavior. Building upon these studies, the present article assesses whether parental and peer drinking behaviors have direct and indirect effects on adolescent drinking and driving as well as whether they moderate the effect of adolescent drinking on their drinking-and-driving behavior. The assessment is conducted using data collected from the Buffalo Longitudinal Survey of Young Men (BLSYM) with Ordinary Least Squares (OLS) regression analyses. The data reveal that peer drinking has direct and indirect effects on adolescent drinking-and-driving behavior when adolescent drinking behavior is controlled. It also moderates the effect of adolescent drinking behavior on their drinking and driving. However, parental drinking does not have these direct and interactive effects, although it may have an indirect effect on adolescent drinking and driving via adolescent drinking behavior. These findings imply that peer drinking behavior should be considered seriously in prevention and intervention for reducing the risk of adolescent drinking-and-driving behavior.

This paper investigates the relationship between the concept of activity (including both professional and nonprofessional) and cognitive functioning among older European individuals. In this research, we used data collected during the first wave of SHARE (Survey on Health, Ageing and Retirement in Europe), and a measurement approach known as stochastic frontier analysis, derived from the economic literature. SHARE includes a large population (n > 25,000) geographically distributed across Europe, and analyzes several dimensions simultaneously, including physical and mental health activity. The main advantages of stochastic frontier analysis are that it allows estimation of parametric function relating cognitive scores and driving factors at the boundary and disentangles frontier noise and distance to frontier components, as well as testing the effect of potential factors on these distances simultaneously. The analysis reveals that all activities are positively related to cognitive functioning in elderly people. Our results are discussed in terms of prevention of cognitive aging and Alzheimer’s disease, and regarding the potential impact that some retirement programs might have on cognitive functioning in individuals across Europe.

The driving performance of individuals with mild cognitive impairment (MCI) is suboptimal when compared to healthy older adults. It is expected that the driving will worsen with the progression of the cognitive decline and thus, whether or not these individuals should continue to drive is a matter of debate. The aim of the study was to provide support to the claim that individuals with MCI can benefit from a training program and improve their overall driving performance in a driving simulator. Fifteen older drivers with MCI participated in five training sessions in a simulator (over a 21-day period) and in a 6-month recall session. During training, they received automated auditory feedback on their performance when an error was noted about various maneuvers known to be suboptimal in MCI individuals (for instance, weaving, omitting to indicate a lane change, to verify a blind spot, or to engage in a visual search before crossing an intersection). The number of errors was compiled for eight different maneuvers for all sessions. For the initial five sessions, a gradual and significant decrease in the number of errors was observed, indicating learning and safer driving. The level of performance, however, was not maintained at the 6-month recall session. Nevertheless, the initial learning observed opens up possibilities to undertake more regular interventions to maintain driving skills and safe driving in MCI individuals.

Mileage, car ownership, experience of punishment avoidance, and the risky driving of young drivers.

2011-12-01

Young drivers are at greatest risk of injury or death from a car crash in the first 6 months of independent driving. In Queensland, the graduated driver licensing (GDL) program was extensively modified in July 2007 in order to reduce this risk. Increased mileage and car ownership have been found to play a role in risky driving, offenses, and crashes; however, GDL programs typically do not consider these variables. In addition, young novice drivers' experiences of punishment avoidance have not previously been examined. This article explores the mileage (duration and distance), car ownership, and punishment avoidance behaviors of young newly licensed intermediate (provisional) drivers and their relationship to risky driving, crashes, and offenses. Drivers (n = 1032) aged 17 to 19 years recruited from across Queensland for longitudinal research completed survey 1 exploring prelicense and learner experiences and sociodemographic characteristics. survey 2 explored the same variables with a subset of these drivers (n = 341) after they had completed their first 6 months of independent driving. Most young drivers in survey 2 reported owning a vehicle and paying attention to police presence. Drivers who had their own cars reported significantly greater mileage and more risky driving. Novices who drove more kilometers, spent more hours each week driving, or avoided actual and anticipated police presence were more likely to report risky driving. These drivers were also more likely to report being detected by police for a driving-related offense. The media, parents, friends, and other drivers play a pivotal role in informing novices of on-road police enforcement operations. GDL programs should incorporate education for the parent and novice driver regarding the increased risks associated with greater driving, particularly when the novice driver owns a vehicle. Parents should be encouraged to delay exclusive access to a vehicle. Parents should also consider whether their young novices will deliberately avoid police if they are aware of their location. This may reinforce not only the risky behavior but also young novices' beliefs that their parents condone this behavior.

Glutathione Decrement Drives Thermogenic Program In Adipose Cells.

Adipose tissue metabolically adapts to external stimuli. We demonstrate that the induction of the thermogenic program in white adipocytes, through cold exposure in mice or in vitro adrenergic stimulation, is accompanied by a decrease in the intracellular content of glutathione (GSH). Moreover, the treatment with a GSH depleting agent, buthionine sulfoximine (BSO), recapitulates the effect of cold exposure resulting in the induction of thermogenic program. In particular, BSO treatment leads to enhanced uncoupling respiration as demonstrated by increased expression of thermogenic genes (e.g. Ucp1, Ppargc1a), augmented oxygen consumption and decreased mitochondrial transmembrane potential. Buffering GSH decrement by pre-treatment with GSH ester prevents the up-regulation of typical markers of uncoupling respiration. We demonstrate that FoxO1 activation is responsible for the conversion of white adipocytes into a brown phenotype as the "browning" effects of BSO are completely abrogated in cells down-regulating FoxO1. In mice, the BSO-mediated up-regulation of uncoupling genes results in weight loss that is at least in part ascribed to adipose tissue mass reduction. The induction of thermogenic program has been largely proposed to counteract obesity-related diseases. Based on these findings, we propose GSH as a novel therapeutic target to increase energy expenditure in adipocytes.

Adipose tissue metabolically adapts to external stimuli. We demonstrate that the induction of the thermogenic program in white adipocytes, through cold exposure in mice or in vitro adrenergic stimulation, is accompanied by a decrease in the intracellular content of glutathione (GSH). Moreover, the treatment with a GSH depleting agent, buthionine sulfoximine (BSO), recapitulates the effect of cold exposure resulting in the induction of thermogenic program. In particular, BSO treatment leads to enhanced uncoupling respiration as demonstrated by increased expression of thermogenic genes (e.g. Ucp1, Ppargc1a), augmented oxygen consumption and decreased mitochondrial transmembrane potential. Buffering GSH decrement by pre-treatment with GSH ester prevents the up-regulation of typical markers of uncoupling respiration.

To compare the on-road driving performance of visually impaired drivers using bioptic telescopes with age-matched controls. Participants included 23 persons (mean age = 33 ± 12 years) with visual acuity of 20/63 to 20/200 who were legally licensed to drive through a state bioptic driving program, and 23 visually normal age-matched controls (mean age = 33 ± 12 years). On-road driving was assessed in an instrumented dual-brake vehicle along 14.6 miles of city, suburban, and controlled-access highways. Two backseat evaluators independently rated driving performance using a standardized scoring system. Vehicle control was assessed through vehicle instrumentation and video recordings used to evaluate head movements, lane-keeping, pedestrian detection, and frequency of bioptic telescope use. Ninety-six percent (22/23) of bioptic drivers and 100% (23/23) of controls were rated as safe to drive by the evaluators. There were no group differences for pedestrian detection, or ratings for scanning, speed, gap judgments, braking, indicator use, or obeying signs/signals. Bioptic drivers received worse ratings than controls for lane position and steering steadiness and had lower rates of correct sign and traffic signal recognition. Bioptic drivers made significantly more right head movements, drove more often over the right-hand lane marking, and exhibited more sudden braking than controls. Drivers with central vision loss who are licensed to drive through a bioptic driving program can display proficient on-road driving skills. This raises questions regarding the validity of denying such drivers a license without the opportunity to train with a bioptic telescope and undergo on-road evaluation.

To determine trends in the numbers of drive-by shootings, individuals shot at, innocent bystanders shot at, and homicides by drive-by shootings in the city of Los Angeles from 1989 to 1993. A retrospective analysis of police records was performed for all gang-related drive-by shootings that occurred in the city of Los Angeles between 1989 and 1993. From 1989 to 1993, there were 6,327 drive-by shootings, 9,053 people shot at, and 590 homicides. There was an increase in drive-by shootings, people shot at, and homicides between 1989 and 1991, followed by a decrease between 1991 and 1993. The case fatality ratio of individuals killed to individuals shot at increased from 1989 to 1993 (p = 0.0011). Forty-seven percent of the people shot at, and 23% of the homicide victims, were innocent bystanders. Drive-by shootings are a major public health problem in Los Angeles. While the rate of drive-by shootings decreased in 1992 and 1993, the proportion of fatal cases increased. To prevent drive-by shootings, the root causes of violent street gang formation must be addressed.

Motor vehicle crashes are the leading cause of death among teens in the United States. Graduated driver licensing (GDL) programs allow new drivers to gain driving experience while protecting them from high-risk situations. North Dakota was one of the last states to implement GDL, and the current program does not meet all of the best practice recommendations. This study used qualitative techniques to explore parents' perceptions of the role teen driving plays in the daily lives of rural North Dakota families, their understanding of the risks faced by their novice teen drivers, and their support for GDL. A total of 28 interviews with parents of teens aged 13-16 years were conducted in four separate rural areas of the state. During the face-to-face interviews, parents described their teens' daily lives as busy, filled with school, sports, and other activities that often required traveling considerable distances. Participation in school-sponsored sports and other school-related activities was highly valued. There was nearly unanimous support for licensing teens at age 14½, as was permitted by law at the time of the interviews. Parents expressed that they were comfortable supervising their teen's practice driving, and few reported using resources to assist them in this role. Although few parents expressed concerns over nighttime driving, most parents supported a nighttime driving restriction with exemptions for school, work or sports-related activities. Despite many parents expressing concern over distracted driving, there was less consistent support among parents for passenger restrictions, especially if there would be no exemptions for family members or school activities. These findings can assist in planning policies and programs to reduce crashes among novice, teen drivers, while taking into account the unique perspectives and lifestyles of families living in rural North Dakota.

This program is largely funded by the CAP Foundation (College of American Pathologists, Northfield, Illinois) and is a collaborative effort among several medical specialties united to address gaps in the current health care system. - To provide an outline for administering a See, Test & Treat program, using an academic medical center as a model for providing care and collating the results of 5 years of data on the See, Test & Treat program's findings. - Sources include data from patients seen at Tufts Medical Center (Boston, Massachusetts) who presented to the See, Test & Treat program and institutional data between 2010 and 2014 detailing the outline of how to organize and operationalize a volunteer cancer-screening program. - During the 5-year course of the program, 203 women were provided free cervical and breast cancer screening. Of the 169 patients who obtained Papanicolaou screening, 36 (21.3%) had abnormal Papanicolaou tests. In addition, 16 of 130 patients (12.3%) who underwent mammography had abnormal findings. - In general, women from ethnic populations have barriers that prevent them from participating in cancer screening. However, the CAP Foundation's See, Test & Treat program is designed to reduce those barriers for these women by providing care that addresses cultural, financial, and practical issues. Although screening programs are helpful in identifying those who need further treatment, obtaining further treatment for these patients continues to be a challenge.

Conceptual designs of the two recommended aircraft were performed and cost and schedule data for the entire testbed program were generated. The program total cost was estimated and a wind tunnel program cost and schedule is generated in support of the testbed program.

The unintended effects of providing risk information about drinking and driving.

PubMed

Johnson, Mark B; Kopetz, Catalina E

2017-09-01

Alcohol-impaired driving remains a serious public health concern despite the fact that drinking and driving risks are widely disseminated and well understood by the public. This research examines the motivational conditions under which providing risk information can exacerbate rather than decrease potential drinking drivers' willingness to drive while impaired. In a hypothetical drinking and driving scenario, 3 studies investigated participants' self-reported likelihood of drinking and driving as a function of (a) accessibility of information regarding risk associated with drinking and driving, (b) motivation to drive, and (c) need for cognitive closure (NFC). Across the 3 studies, participants self-reported a higher likelihood of driving when exposed to high-risk information (vs. low-risk information) if they were high in NFC. Risk information did decrease self-reported likelihood of driving among low-NFC participants (Studies 1-3). Furthermore, this effect was exacerbated when the relevant motivation (to get home conveniently) was high (Study 3). These findings have important implications for impaired-driving prevention efforts. They suggest that at least under some circumstances, risk information can have unintended negative effects on drinking and driving decisions. The results are consistent with the motivated cognition literature, which suggests that people process and use information in a manner that supports their most accessible and important motivation despite potentially negative consequences.

The purpose of this document is to define, document, and allocate the Human Research Program (HRP) requirements to the HRP Program Elements. It establishes the flow-down of requirements from Exploration Systems Mission Directorate (ESMD) and Office of the Chief Health and Medical Officer (OCHMO) to the various Program Elements of the HRP to ensure that human research and technology countermeasure investments are made to insure the delivery of countermeasures and technologies that satisfy ESMD's and OCHMO's exploration mission requirements. Requirements driving the HRP work and deliverables are derived from the exploration architecture, as well as Agency standards regarding the maintenance of human health and performance. Agency human health and performance standards will define acceptable risk for each type and duration of exploration mission. It is critical to have the best available scientific and clinical evidence in setting and validating these standards. In addition, it is imperative that the best available evidence on preventing and mitigating human health and performance risks is incorporated into exploration mission and vehicle designs. These elements form the basis of the HRP research and technology development requirements and highlight the importance of HRP investments in enabling NASA's exploration missions. This PRD defines the requirements of the HRP which is comprised of the following major Program Elements: Behavioral Health and Performance (BHP), Exploration Medical Capability (ExMC), Human Health Countermeasures (HHC), ISS Medical Project (ISSMP), Space Human Factors and Habitability (SHFH), and Space Radiation (SR).

Gaines, Jean M; Burke, Kasey L; Marx, Katherine A; Wagner, Mary; Parrish, John M

2011-10-01

To evaluate CarFit, an educational program designed to promote optimal alignment of driver with vehicle. A driving activity survey was sent to 727 randomly selected participants living in retirement communities. Drivers (n=195) were assigned randomly to CarFit intervention (n=83, M age=78.1) or Comparison (n=112, M age=79.6) groups. After 6months, participants completed a post-test of driving activity and CarFit recommendations. Nonconsenting drivers were older and participated in fewer driving activities. CarFit participation was moderate (71%) with 86% of the participants receiving recommendations. 60% followed the recommendations at the 6-month re-evaluation). The CarFit (67.6%) and Comparison (59.3%) groups reported at least one type of self-regulation of driving activity at baseline. There was no significant change in the driving behaviors at the six-month follow-up. CarFit was able to detect addressable opportunities that may contribute to the safety of older drivers. CarFit recommendations may need stronger reinforcement in order to be enacted by a participant. Copyright © 2011 National Safety Council and Elsevier Ltd. All rights reserved.

Properly selected and maintained chain drives can be expected to give thousands of hours of reliable service. Selection is usually done just once. This paper reports on good maintenance which must be done regularly to keep the drive operating. An effective maintenance program for roller chain should include correct type and adequate amounts of lubrication, replacement of worn chains and sprockets, and elimination of drive interferences. It is important to set u a lubrication and inspection/correction schedule to ensure that all required maintenance is carried out.

Risky driving behaviors in Tehran, Iran.

Shams, Mohsen; Rahimi-Movaghar, Vafa

2009-03-01

Iran has one of the highest fatality rates due to road traffic crashes (RTC) in the world. The disability adjusted life years (DALYs) for RTC in Iran is more than 1,300,000 years, which is more than that for any other disease such as cardiovascular or cancer. We evaluated risky driving behaviors in Tehran, the capital of Iran. A retrospective analysis was conducted based on the data obtained from the Tehran Police Safety Driving Department. Offenses and crashes were studied in different municipal districts in Tehran from March 2006 to March 2007. The inclusion criteria were risky driving behaviors fined by the police. Nonbehavioral offences were excluded. There were 3,821,798 offenses in Tehran. Not wearing a seat belt was the most common (59%) example of risky driving behavior, followed by tailgating, not wearing motorcycle helmets, talking on the cell phone while driving, overtaking from the wrong side, speeding, not driving between the lanes, weaving in and out of traffic, left deviation, and changing lanes without signals. The most common causes of RTC in Tehran are speeding, overtaking from the wrong side, and the rapid changing of driving lanes. The study factors effective in preventing risky driving behaviors in Tehran is recommended. The consideration of specific characteristics of the municipal districts is necessary to reduce risky driving behaviors.

Novel CRISPR/Cas9 gene drive constructs reveal insights into mechanisms of resistance allele formation and drive efficiency in genetically diverse populations

PubMed Central

Liu, Chen

2017-01-01

A functioning gene drive system could fundamentally change our strategies for the control of vector-borne diseases by facilitating rapid dissemination of transgenes that prevent pathogen transmission or reduce vector capacity. CRISPR/Cas9 gene drive promises such a mechanism, which works by converting cells that are heterozygous for the drive construct into homozygotes, thereby enabling super-Mendelian inheritance. Although CRISPR gene drive activity has already been demonstrated, a key obstacle for current systems is their propensity to generate resistance alleles, which cannot be converted to drive alleles. In this study, we developed two CRISPR gene drive constructs based on the nanos and vasa promoters that allowed us to illuminate the different mechanisms by which resistance alleles are formed in the model organism Drosophila melanogaster. We observed resistance allele formation at high rates both prior to fertilization in the germline and post-fertilization in the embryo due to maternally deposited Cas9. Assessment of drive activity in genetically diverse backgrounds further revealed substantial differences in conversion efficiency and resistance rates. Our results demonstrate that the evolution of resistance will likely impose a severe limitation to the effectiveness of current CRISPR gene drive approaches, especially when applied to diverse natural populations.

Improvement in Brightness Uniformity by Compensating for the Threshold Voltages of Both the Driving Thin-Film Transistor and the Organic Light-Emitting Diode for Active-Matrix Organic Light-Emitting Diode Displays

NASA Astrophysics Data System (ADS)

Ching-Lin Fan,; Hui-Lung Lai,; Jyu-Yu Chang,

2010-05-01

In this paper, we propose a novel pixel design and driving method for active-matrix organic light-emitting diode (AM-OLED) displays using low-temperature polycrystalline silicon thin-film transistors (LTPS-TFTs). The proposed threshold voltage compensation circuit, which comprised five transistors and two capacitors, has been verified to supply uniform output current by simulation work using the automatic integrated circuit modeling simulation program with integrated circuit emphasis (AIM-SPICE) simulator. The driving scheme of this voltage programming method includes four periods: precharging, compensation, data input, and emission. The simulated results demonstrate excellent properties such as low error rate of OLED anode voltage variation (<1%) and high output current. The proposed pixel circuit shows high immunity to the threshold voltage deviation characteristics of both the driving poly-Si TFT and the OLED.

After a Spirit Drive West of Home Plate

NASA Image and Video Library

2009-04-20

NASA's Mars Exploration Rover Spirit drove 6.98 meters (22.9 feet) southeastward on the 1,871st Martian day, or sol, of the rover's mission on Mars (April 8, 2009). As usual since losing the use of its right-front wheel in 2006, Spirit drove backward, dragging the immobile wheel. The rover used its front hazard-avoidance camera after the drive to capture this view looking back at the ground covered. For scale, the distance between the parallel wheel tracks is about 1 meter (40 inches). The drive added to progress in trekking counterclockwise around a low plateau called "Home Plate." Spirit is driving through a valley on the west side of the plateau. Home Plate is not within this image. The hill on the horizon in the upper right is Husband Hill, the summit of which is about 750 meters (nearly half a mile) to the north of Spirit's position. Following this drive, Spirit experienced difficulties that prevented driving during the subsequent week. http://photojournal.jpl.nasa.gov/catalog/PIA11990

Wabble gear drive mechanism. [for aerospace environments

NASA Technical Reports Server (NTRS)

Winiarski, F. J. (Inventor)

1967-01-01

The wabble gear principle was applied in the design of a driving mechanism for controlling spacecraft solar panels. The moving elements, other than the output gear, are contained within a hermetically sealed package to prevent escape of lubricants and ingestion of contaminant particles. The driving gear contains one more tooth than the output gear on a concave, conical pitch surface of slightly larger apex angle. The two gears mesh face to face such that engagement takes place at one point along the circumference. The driving gear is not permitted to rotate by virtue of its attachment through the bellows which permits flexure in the pitch and yaw position, but not in roll. As the bearing carrier rotates, the inclined mounting of the bearing causes the driving gear to perform a wabbling, irrotational motion. This wabbling motion causes the contact point between the output gear and the driving gear to traverse around the circumference of the gears once per revolution of the bearing carrier.

Views of US drivers about driving safety.

PubMed

Williams, Allan F

2003-01-01

To assess how drivers view dangers on the highway, what motivates them to drive safely, how they say they reduce their crash and injury risk, and how they rate their own driving skills. Most drivers rated their skills as better than average. The biggest motivating factor for safe driving was concern for safety of others in their vehicle, followed by negative outcomes such as being in a crash, increased insurance costs, and fines. The greatest threats to their safety were thought to be other drivers' actions that increase crash risk such as alcohol impairment or running red lights. In terms of reducing crashes and injuries, drivers tended to focus on actions they could take such as driving defensively or using seat belts. There was less recognition of the role of vehicles and vehicle features in crash or injury prevention. Knowing how drivers view themselves and others, their concerns, and their motivations and techniques for staying out of trouble on the roads provides insight into the difficulty of changing driving practices.

Special Considerations in Distracted Driving with Teens

Durbin, Dennis R; McGehee, Daniel V; Fisher, Donald; McCartt, Anne

2014-01-01

Novice teen drivers have long been known to have an increased risk of crashing, as well as increased tendencies toward unsafe and risky driving behaviors. Teens are unique as drivers for several reasons, many of which have implications specifically in the area of distracted driving. This paper reviews several of these features, including the widespread prevalence of mobile device use by teens, their lack of driving experience, the influence of peer passengers as a source of distraction, the role of parents in influencing teens’ attitudes and behaviors relevant to distracted driving and the impact of laws designed to prevent mobile device use by teen drivers. Recommendations for future research include understanding how engagement in a variety of secondary tasks by teen drivers affects their driving performance or crash risk; understanding the respective roles of parents, peers and technology in influencing teen driver behavior; and evaluating the impact of public policy on mitigating teen crash risk related to driver distraction.

Findings indicate that MMLs in general have a null effect on cannabis-positive driving, as do state laws with specific supply provisions including home cultivation and unlicensed or quasi-legal dispensaries. Only in jurisdictions with state-licensed medical marijuana dispensaries did the odds of marijuana-involved driving increase significantly by 14 percent, translating into an additional 87 to 113 drivers testing positive for marijuana per year. Sensitivity analyses reveal these findings to be generally robust to alternate specifications, although an observed spillover effect consistent with elevated drugged driving enforcement in bordering states weakens a causal interpretation. Still, reasonable policy implications are drawn regarding drugged driving prevention/enforcement and regulations governing dispensary delivery services and business siting decisions.

Background In Iran, traffic accidents and deaths from traffic accidents are among the highest in the world, and generally driver behavior rather than either technical failures or environmental conditions are responsible for traffic accidents. In the present study, we explored the extent to which aggressive traits, health status, and sociodemographic variables explain driving behavior among Iranian male traffic offenders. Method A total of 443 male driving offenders (mean age: M =31.40 years, standard deviation =9.56) from Kermanshah (Iran) took part in the study. Participants completed a questionnaire booklet covering sociodemographic variables, traits of aggression, health status, and driving behavior. Results Poor health status, such as symptoms of depression, anxiety, insomnia, and social dysfunction, and also higher levels of trait aggression explained poor driving behavior. Multiple regressions indicated that poor health status, but not aggression, independently predicted poor driving behavior. Conclusion Results suggest that health status concerns are associated with poor driving behavior. Prevention and intervention might therefore focus on drivers reporting poor mental health status.

We aimed to study the association between low back pain (LBP) and exposure to low temperature, wet clothes, heavy lifting and jobs that involve whole body vibration (WBV) in a population of miners. Health and personal data were collected in a population study by a questionnaire. A total of 3530 workers from four mines participated in the study. 51% of the workers reported LBP within the last 12 months. The adjusted odds ratio for LBP was above unity for working with wet clothes (1.82), working in cold conditions (1.52), lifting heavy (1.54), having worked as a driver previously (1.79) and driving Toro400 (2.61) or train (1.69). Wet clothing, cold working conditions, heavy lifting, previous work as a driver and driving certain vehicles were associated with LBP, but vehicles with WBV levels above action value were not. For better prevention of LBP, improved cabin conditions and clothing should be emphasised. To address risk factors for low back pain (LBP) in miners, a population study measured exposures and LBP. Cold work conditions, wet clothes and awkward postures appeared to be more strongly associated with LBP than exposure to whole body vibration from driving heavy vehicles. Prevention strategies must focus more on clothing and ergonomics.

The aim of the present study is to analyse factors affecting worries, coping strategies and decisions of young drivers regarding the risk of sleep-related car crashes. Furthermore, the study also analyses whether framing the same information about sleepiness in two different linguistic forms influences: (1) the evaluation of the level of risk associated to a specific level of drowsiness (Attribute Framing problem); (2) the willingness to enact strategies to "prevent" sleepiness before night-time driving (Goal Framing problem); (3) the choice between two different ways, both of equal expected efficacy, of lowering drowsiness (Risky decision-making Framing problem). Six hundred and ninety-five young drivers [(57.6% females, 42.4% males); mean age 20.85 years (S.D.=1.2)] answered questions on drive risk perception and sleepiness, on nocturnal driving experience and on the strategies to deal with driver sleepiness, responding to one of the two different versions of the framed problems. A sub-sample of 130 participants completed the framed problems in both versions. The results show that experiences of sleep attacks and nocturnal driving frequency in the past 6 months affect both risk perception and the preventive strategies adopted. Furthermore, the manipulation on two out of the three problems (attribute and risky decision-making frames) significantly affected the respondents' evaluation.

Invulnerability and the intention to drink and drive: an application of the theory of planned behavior.

Chan, Daphne C N; Wu, Anise M S; Hung, Eva P W

2010-11-01

The present study aims at an examination, based on the theory of planned behavior (TPB), of the psychological antecedents of young Chinese people's intentions to drive after drinking. One hundred and twenty-four licensed drivers (aged from 19 to 35 years) successfully completed an online questionnaire. Using path analysis, we found the most proximal predictors of intention to be attitudes and perceived behavioral control, whereas invulnerability as well as subjective norms indirectly influenced intention by promoting favorable attitudes toward and greater perceived behavioral control over driving after alcohol use. The total explained variances in the intention to drink and drive reached 79%. The present findings highlight irrational beliefs of invulnerability and the three TPB components as potentially valid targets for prevention and intervention efforts against drinking and driving among young Chinese drivers. 2010 Elsevier Ltd.

Promising practices in the prevention of intimate partner violence among adolescents.

PubMed

De Grace, Alyssa; Clarke, Angela

2012-01-01

To inform practitioners and researchers interested in the prevention of intimate partner violence (IPV) among adolescents, 9 principles of effective prevention programs (Nation et al., 2003) were described and examples of how these principles have been incorporated into existing teen dating violence prevention programs were provided. An investigation of current prevention practices for adolescent IPV resulted in one noteworthy program that has successfully incorporated all 9 principles of effective prevention programming-Safe Dates (Substance Abuse and Mental Health Services Administration, National Registry of Evidence-based Programs and Practices [SAMHSA-NREPP], 2006). Although Safe Dates serves as a model teen dating violence prevention program, it may not be equally effective across contexts and diverse groups. Therefore, as researchers and practitioners continue to develop and refine programs to reduce adolescent IPV, the principles of effective prevention programs should serve as a guiding framework.

Effectiveness of graduated driver licensing in reducing motor vehicle crashes.

PubMed

Foss, R D; Evenson, K R

1999-01-01

To determine whether graduated driver licensing (GDL) systems and nighttime curfews reduce motor vehicle crashes, fatalities, or injuries among young drivers. We used Cochrane Collaboration search strategies to locate studies of graduated licensing or night driving restrictions. Studies were selected if they examined the effects of either (1) a comprehensive graduated driver licensing system including well-integrated components, or (2) nighttime driving restrictions/curfews that could affect young persons' nighttime driving, on a clearly defined crash or injury outcome. Seven studies met inclusion criteria. Two independent studies of the New Zealand graduated licensing program found a sustained 7%-8% reduction in teen driver crash injuries attributable to the program. No other full graduated licensing system has been evaluated to date. Four studies of either a general curfew or a nighttime driving restriction for teens, a key element of graduated licensing, found substantial crash reductions during restricted hours, with 23%-25% lower crash injury and fatality rates for curfews beginning prior to midnight. One study found no change in late night crashes before and after a 1 a.m.-6 a.m. night driving restriction took effect. The logic and empirical bases for graduated licensing are sound. Moreover, there is evidence that one central element, a restriction on nighttime driving by novices, reduces young driver crashes. However, a definitive conclusion about the effectiveness of GDL systems for reducing motor vehicle crashes or crash-related injuries must await examination of other GDL systems. This should be possible within the next few years, as several states and Canadian provinces have recently enacted GDL programs.

2016-01-01

To examine pre- and post-injury self-reported driver behaviour and safety in individuals with traumatic brain injury (TBI) who returned to driving after occupational therapy driver assessment and on-road rehabilitation. A self-report questionnaire, administered at an average of 4.5 years after completing an on-road driver assessment, documenting pre- and post-injury crash rates, near-crashes, frequency of driving, distances driven, driving conditions avoided and navigation skills, was completed by 106 participants, who had either passed the initial driver assessment (pass group n = 74), or required driver rehabilitation, prior to subsequent assessments (rehabilitation group n = 32). No significant difference was found between pre- and post-injury crash rates. Compared to pre-injury, 36.8% of drivers reported limiting driving time, 40.6% drove more slowly, 41.5% reported greater difficulty with navigating and 20.0% reported more near-crashes. The rehabilitation group (with greater injury severity) was significantly more likely to drive less frequently, shorter distances, avoid: driving with passengers, busy traffic, night and freeway driving than the pass group. Many drivers with moderate/severe TBI who completed a driver assessment and rehabilitation program at least 3 months post-injury, reported modifying their driving behaviour, and did not report more crashes compared to pre-injury. On-road driver training and training in navigation may be important interventions in driver rehabilitation programs. Driver assessment and on-road retraining are important aspects of rehabilitation following traumatic brain injury. Many drivers with moderate/severe TBI, reported modifying their driving behaviour to compensate for ongoing impairment and continued to drive safely in the longer term. Navigational difficulties were commonly experienced following TBI, suggesting that training in navigation may be an important aspect of driver rehabilitation.

Characteristics of On-Road Driving Performance of Persons With Central Vision Loss Who Use Bioptic Telescopes

Purpose. To compare the on-road driving performance of visually impaired drivers using bioptic telescopes with age-matched controls. Methods. Participants included 23 persons (mean age = 33 ± 12 years) with visual acuity of 20/63 to 20/200 who were legally licensed to drive through a state bioptic driving program, and 23 visually normal age-matched controls (mean age = 33 ± 12 years). On-road driving was assessed in an instrumented dual-brake vehicle along 14.6 miles of city, suburban, and controlled-access highways. Two backseat evaluators independently rated driving performance using a standardized scoring system. Vehicle control was assessed through vehicle instrumentation and video recordings used to evaluate head movements, lane-keeping, pedestrian detection, and frequency of bioptic telescope use. Results. Ninety-six percent (22/23) of bioptic drivers and 100% (23/23) of controls were rated as safe to drive by the evaluators. There were no group differences for pedestrian detection, or ratings for scanning, speed, gap judgments, braking, indicator use, or obeying signs/signals. Bioptic drivers received worse ratings than controls for lane position and steering steadiness and had lower rates of correct sign and traffic signal recognition. Bioptic drivers made significantly more right head movements, drove more often over the right-hand lane marking, and exhibited more sudden braking than controls. Conclusions. Drivers with central vision loss who are licensed to drive through a bioptic driving program can display proficient on-road driving skills. This raises questions regarding the validity of denying such drivers a license without the opportunity to train with a bioptic telescope and undergo on-road evaluation. PMID:23640044

The Influence of Parental and Peer Drinking Behaviors on Underage Drinking and Driving by Young Men*

PubMed Central

Zhang, Lening; Wieczorek, William F.; Welte, John W.

2013-01-01

Background Studies have consistently found that parental and peer drinking behaviors significantly influence adolescent drinking behavior and that adolescent drinking has a significant effect on their drinking-and-driving behavior. Building upon these studies, the present article assesses whether parental and peer drinking behaviors have direct and indirect effects on adolescent drinking and driving as well as whether they moderate the effect of adolescent drinking on their drinking-and-driving behavior. Methods The assessment is conducted using data collected from the Buffalo Longitudinal Survey of Young Men (BLSYM) with Ordinary Least Squares (OLS) regression analyses. Results The data reveal that peer drinking has direct and indirect effects on adolescent drinking-and-driving behavior when adolescent drinking behavior is controlled. It also moderates the effect of adolescent drinking behavior on their drinking and driving. However, parental drinking does not have these direct and interactive effects, although it may have an indirect effect on adolescent drinking and driving via adolescent drinking behavior. Conclusions These findings imply that peer drinking behavior should be considered seriously in prevention and intervention for reducing the risk of adolescent drinking-and-driving behavior.

Recent advances in the understanding of antibiotic resistance in Clostridium difficile infection

PubMed Central

2016-01-01

Clostridium difficile epidemiology has changed in recent years, with the emergence of highly virulent types associated with severe infections, high rates of recurrences and mortality. Antibiotic resistance plays an important role in driving these epidemiological changes and the emergence of new types. While clindamycin resistance was driving historical endemic types, new types are associated with resistance to fluoroquinolones. Furthermore, resistance to multiple antibiotics is a common feature of the newly emergent strains and, in general, of many epidemic isolates. A reduced susceptibility to antibiotics used for C. difficile infection (CDI) treatment, in particular to metronidazole, has recently been described in several studies. Furthermore, an increased number of strains show resistance to rifamycins, used for the treatment of relapsing CDI. Several mechanisms of resistance have been identified in C. difficile, including acquisition of genetic elements and alterations of the antibiotic target sites. The C. difficile genome contains a plethora of mobile genetic elements, many of them involved in antibiotic resistance. Transfer of genetic elements among C. difficile strains or between C. difficile and other bacterial species can occur through different mechanisms that facilitate their spread. Investigations of the fitness cost in C. difficile indicate that both genetic elements and mutations in the molecular targets of antibiotics can be maintained regardless of the burden imposed on fitness, suggesting that resistances may persist in the C. difficile population also in absence of antibiotic selective pressure. The rapid evolution of antibiotic resistance and its composite nature complicate strategies in the treatment and prevention of CDI. The rapid identification of new phenotypic and genotypic traits, the implementation of effective antimicrobial stewardship and infection control programs, and the development of alternative therapies are needed to prevent and contain the spread of resistance and to ensure an efficacious therapy for CDI.

After epidemiological research: what next? Community action for health promotion.

PubMed

Cwikel, J G

1994-01-01

The underlying purpose of all epidemiological research is ultimately to use inferences in order to prevent disease and promote health and well-being. Effective skills in translating results into appropriate policy, programs, and interventions are inherently tricky, and often politically controversial. Generally they are not taught to epidemiologists formally, even though they are a traditionally part of public health practice. To move from findings to policy change requires that the informed and committed epidemiologist should known how to: (1) organize affected parties to negotiate successfully with government and industry; (2) activate populations at risk to protect their health (3) communicate responsibly with lay persons about their health risks so as to encourage effective activism; (4) collaborate with other professionals to achieve disease prevention and health promotion goals. The paper presents and discusses four case studies to illustrate these strategies: (1) the grass-roots social action that was the response of the community to the environmental contamination at Love Canal, New York; (2) mobilization of recognized leaders within the gay community to disseminate HIV risk reduction techniques; (3) collaboration with an existing voluntary organization interested in community empowerment through health promotion in a Chicago slum by using existing hospital, emergency room admissions, and local motor vehicle accident data; (4) a self-help group, MADD (mothers against drunk driving) which fought to change public policy to limit and decrease drunk driving. In addition, the importance of multidisciplinary collaboration and responsible communication with the public is emphasized. Factors that limit the ability of the epidemiologist to move into public health action are discussed, including who owns the research findings, what is the degree of scientific uncertainty, and the cost-benefit balance of taking affirmative public action. Putting epidemiological knowledge to good use should be an integral part of an epidemiologist's repertoire.

2014-03-01

Parenting practices for teen drivers with ADHD were observed via a video monitor installed in vehicles. All teens had recently completed a driver education course and were in the driving permit stage of a graduated driver-licensing program. Parent behaviors were coded during drives when teens were driving safely and during drives when teens engaged in risky driving. The overall frequency of positive parenting strategies was low, regardless of whether teens drove safely or engaged in risky driving. Although the rate of negative feedback was also low, parents engaged in significantly more criticism and were rated by an observer to appear angrier when teens were driving in a risky manner. No other differences in parent behaviors associated with the quality of teen driving were observed. The inconsistencies between observed parenting behaviors and those parenting practices recommended as effective with teens with ADHD are discussed. The need for further research addressing effective strategies for teaching teens with ADHD to drive is highlighted. © 2013.

2014-01-01

We examine the association between exposure to depictions of reckless driving in movies and unsafe driving, modeling inattentive and reckless driving as separate outcomes. Data were obtained by telephone from 1,630 US adolescents aged 10 to 14 years at baseline who were drivers at a survey 6 years later. Exposure to movie reckless driving was measured based on movies seen from a randomly selected list of 50 movie titles that had been content coded for reckless driving among characters. Associations were tested with inattentive and reckless driving behaviors in the subsequent survey-controlling for baseline age, sex, socioeconomic status, parental education, school performance, extracurricular activities, daily television and video/computer game exposure, number of movies watched per week, self-regulation and sensation seeking. Exposure to movie reckless driving was common, with approximately 10% of movie characters having driven recklessly. Confirmatory factor analysis revealed a significant distinction between items tapping reckless and inattentive driving at the 6th wave. Age and exposure to movie reckless driving at baseline were directly associated with wave-6 reckless (but not inattentive) driving. Additionally, growth in sensation seeking mediated a prospective relation between the total number of movies watched per week at baseline and reckless driving, independent of exposure to movie reckless driving. Males and high sensation seekers reported lower seatbelt usage and more reckless driving, whereas lower self-regulation predicted inattentive driving. In this study, exposure to movie reckless driving during early adolescence predicted adolescents' reckless driving, suggesting a direct modeling effect. Other aspects of movies were also associated with reckless driving, with that association mediated through growth in sensation seeking. Predictors of reckless driving were different from predictors of inattentive driving, with lower self-regulation associated with the latter outcome. Making a clear distinction between interventions for reckless or inattentive driving seems crucial for accident prevention.

2017-09-01

: In many areas of the world, driving is an essential part of life and for reasons of comfort, convenience, and security remains the primary mode of transportation among older adults. Both normal aging and diseases that are more prevalent in advanced age can substantially reduce older drivers' functional abilities, elevating their risk of involvement in motor vehicle accidents and serious injury or death. Identifying and intervening with older drivers at increased crash risk is an important aspect of preventive medicine. The authors discuss the specific driving risks adults face as they age and how nurses can raise older patients' awareness of these risks. They also discuss the importance of connecting older adults to community resources that may help them continue driving safely for a longer period or find alternative transportation options.

The effect of fatigue driving on injury severity considering the endogeneity.

PubMed

Li, Yanyan; Yamamoto, Toshiyuki; Zhang, Guangnan

2018-02-01

Fatigue driving is one of the most risky driving-related behaviors and represented a significant social and economic cost to the community. Several studies have already examined the relationship between fatigue driving behavior and traffic injury severity from different aspects. However, fatigue driving and injury severity in traffic crash may share some common influential factors. Ignoring the impact of these common factors will lead to endogeneity problem and result in biased parameter estimation. Based on 38,564 crash records during 2006-2011 in Guangdong province, China, we apply a bivariate endogenous binary-ordered probit model to examine the relationship between fatigue driving and injury severity considering endogeneity of fatigue driving. We also explore the difference of influential factors between commercial and non-commercial vehicle drivers. This study identifies several common observed influential factors of fatigue driving propensity and fatal injury propensity and reveals a substantial and significant negative correlation of unobserved factors between them. The influence of fatigue driving on injury severity is significantly underestimated if the endogeneity of fatigue driving on fatal injury propensity is ignored. Factors such as vehicle insurance and road types not only affect fatal injury propensity, but also fatigue driving propensity. The findings in this study can help better understand how those factors affect fatigue driving and injury severity, and contributes to more efficient policy for preventing the harmfulness of fatigue-related crashes.

Possession attachment predicts cell phone use while driving.

Weller, Joshua A; Shackleford, Crystal; Dieckmann, Nathan; Slovic, Paul

2013-04-01

Distracted driving has become an important public health concern. However, little is known about the predictors of this health-risking behavior. One overlooked risk factor for distracted driving is the perceived attachment that one feels toward his or her phone. Prior research has suggested that individuals develop bonds toward objects, and qualitative research suggests that the bond between young drivers and their phones can be strong. It follows that individuals who perceive a strong attachment to their phone would be more likely to use it, even when driving. In a nationally representative sample of young drivers (17-28 years), participants (n = 1,006) completed a survey about driving behaviors and phone use. Risk perception surrounding cell phone use while driving and perceived attachment to one's phone were assessed by administering factor-analytically derived scales that were created as part of a larger project. Attachment toward one's phone predicted the proportion of trips in which a participant reported using their cell phone while driving, beyond that accounted for by risk perception and overall phone use. Further, attachment predicted self-reported distracted driving behaviors, such as the use of social media while driving. Attachment to one's phone may be an important but overlooked risk factor for the engagement of potentially health-risking driving behaviors. Understanding that phone attachment may adversely affect driving behaviors has the potential to inform prevention and intervention efforts designed to reduce distracted driving behaviors, especially in young drivers. 2013 APA, all rights reserved

To characterise on-road driving performance in individuals with traumatic brain injury who fail on-road driving assessment, compared with both those who pass assessment and healthy controls, and the injury and cognitive factors associated with driving performance. Cross-sectional. Forty eight participants with traumatic brain injury (Age M = 40.50 SD = 14.62, 77% male, post-traumatic amnesia days M = 28.74 SD =27.68) and 48 healthy matched controls completed a standardised on-road driving assessment in addition to cognitive measures. Individuals with traumatic brain injury who passed on-road driving assessment performed no differently from controls while individuals with traumatic brain injury who failed the assessment demonstrated significantly worse driving performance relative to controls across a range of driving manoeuvres and error types including observation of on-road environment, speed control, gap selection, lane position, following distance and basic car control. Longer time post-injury and reduced visual perception were both significantly correlated with reduced driving skills. This exploratory study indicated that drivers with traumatic brain injury who failed on-road assessment demonstrated a heterogeneous pattern of impaired driving manoeuvres, characterised by skill deficits across both operational (e.g., basic car control and lane position) and tactical domains (e.g., following distance, gap selection, and observation) of driving. These preliminary findings can be used for implementation of future driving assessments and rehabilitation programs. Implications for rehabilitation Clinicians should be aware that the majority of individuals with traumatic brain injury were deemed fit to resume driving following formal on-road assessment, despite having moderate to very severe traumatic brain injuries. Drivers with traumatic brain injury who failed an on-road assessment demonstrated a heterogeneous pattern of impaired skills including errors with observation, speed regulation, gap selection, and vehicle control and accordingly had difficulty executing a diverse range of common driving manoeuvres. Comprehensive, formal on-road assessments, incorporating a range of skills, and manoeuvres, are needed to evaluate readiness to return to driving following traumatic brain injury. Individually tailored driver rehabilitation programs need to address these heterogeneous skill deficits to best support individuals to make a successful return to driving post-traumatic brain injury.

During meiosis, crossover recombination is essential to link homologous chromosomes and drive faithful chromosome segregation. Crossover recombination is non-random across the genome, and centromere-proximal crossovers are associated with an increased risk of aneuploidy, including Trisomy 21 in humans. Here, we identify the conserved Ctf19/CCAN kinetochore sub-complex as a major factor that minimizes potentially deleterious centromere-proximal crossovers in budding yeast. We uncover multi-layered suppression of pericentromeric recombination by the Ctf19 complex, operating across distinct chromosomal distances. The Ctf19 complex prevents meiotic DNA break formation, the initiating event of recombination, proximal to the centromere. The Ctf19 complex independently drives the enrichment of cohesin throughout the broader pericentromere to suppress crossovers, but not DNA breaks. This non-canonical role of the kinetochore in defining a chromosome domain that is refractory to crossovers adds a new layer of functionality by which the kinetochore prevents the incidence of chromosome segregation errors that generate aneuploid gametes.

Traffic Accidents—Chronic Medical Conditions as a Cause

PubMed Central

Waller, Julian A.

1966-01-01

From comparatively scanty information, an increased traffic accident risk appears to be associated with several chronic medical conditions including alcoholism, cardiovascular disease, epilepsy, diabetes and mental illness. Further study probably will show that medical handicaps other than alcoholism are a factor in from 5 to 10 per cent of traffic accidents. However, in about half of the accidents caused by heart attacks, the individual has no previous knowledge of his illness, and prevention of the accident would not be possible. A selective program for identifying high risk drivers with medical conditions is feasible and warranted, but a program of mass medical examinations for all drivers is not. A very strong relationship has been shown between drunk driving and traffic accidents, and 50 to 75 per cent of all severe and fatal traffic accidents involve the use of alcohol. However, studies have shown that drivers with alcoholism rather than social drinkers represent the preponderance, but not the entirety, of those who get into trouble. A major reduction in the traffic accident toll may thus depend on the early identification and treatment of alcoholism. PMID:18730024

The informal social control over alcohol consumption that was traditional in Southern European countries has weakened. At the same time there is an increase in binge drinking and drunkenness among young people in Spain. To mitigate this problem, regulations on alcohol and driving and restrictions on the sale and consumption of alcohol have been adopted. This paper documents the current regulations in the city of Barcelona and describes efforts to enforce them and their outcomes. Data from the municipal information systems on infringements reported for the period 2008-13 are provided. There is an increasing pressure of municipal services to enforce the rules in two areas: a) alcohol sales at night (retailers); and b) consumption in the public space (citizens). An increase in the controls of drink-driving has also taken place, and the proportion above legal limits has decreased. The largest relative increase occurred in the control of retailers. In Barcelona interventions are made to limit the supply and consumption of alcohol at low cost and during the night, and of driving under the influence of alcohol. There have been no documented episodes of massive drinking in public spaces (known as 'botellón') in the city. These actions, which complement other preventive efforts based on health education, can change the social perceptions of alcohol by minors in a direction less favorable to consumption, promoting environmental prevention.

Gut microbiota directs PPARγ-driven reprogramming of the liver circadian clock by nutritional challenge.

PubMed

2016-09-01

The liver circadian clock is reprogrammed by nutritional challenge through the rewiring of specific transcriptional pathways. As the gut microbiota is tightly connected to host metabolism, whose coordination is governed by the circadian clock, we explored whether gut microbes influence circadian homeostasis and how they distally control the peripheral clock in the liver. Using fecal transplant procedures we reveal that, in response to high-fat diet, the gut microbiota drives PPARγ-mediated activation of newly oscillatory transcriptional programs in the liver. Moreover, antibiotics treatment prevents PPARγ-driven transcription in the liver, underscoring the essential role of gut microbes in clock reprogramming and hepatic circadian homeostasis. Thus, a specific molecular signature characterizes the influence of the gut microbiome in the liver, leading to the transcriptional rewiring of hepatic metabolism. © 2016 The Authors.

Single-event-induced failure of the Lambda Advanced Analog AMF2805S DC/DC Converter has been traced to burnout of an n-p-n transistor in the MOSFET drive stage. The failures were observed during testing while in inhibit mode only. Modifications to prevent burnout of the drive stage were successfully employed. A discussion of the failure mechanism and consequences for DC/DC converter testing are presented.

2007-12-01

Recent studies have shown that extended shifts worked by hospital staff nurses are associated with significantly higher risk of errors, yet little information is available about the ability to remain alert during the nurses' commutes following the completion of an extended work shift. The purpose of this study is to describe the prevalence of drowsy driving episodes and the relationship between drowsy driving and nurse work hours, alertness on duty, working at night, and sleep duration. Data were collected from 2 national random samples of registered nurses (n=895). Full-time hospital staff nurses (n=895) completed logbooks on a daily basis for 4 weeks providing information concerning work hours, sleep duration, drowsy and sleep episodes at work, and drowsy driving occurrences. Almost 600 of the nurses (596/895) reported at least 1 episode of drowsy driving, and 30 nurses reported experiencing drowsy driving following every shift worked. Shorter sleep durations, working at night, and difficulties remaining awake at work significantly increased the likelihood of drowsy driving episodes. Given the large numbers of nurses who reported struggling to stay awake when driving home from work and the frequency with which nurses reported drowsy driving, greater attention should be paid to increasing nurse awareness of the risks and to implementing strategies to prevent drowsy driving episodes to ensure public safety. Without mitigation, fatigued nurses will continue to put the public and themselves at risk.

Generalized three-dimensional experimental lightning code (G3DXL) user's manual

NASA Technical Reports Server (NTRS)

Kunz, Karl S.

1986-01-01

Information concerning the programming, maintenance and operation of the G3DXL computer program is presented and the theoretical basis for the code is described. The program computes time domain scattering fields and surface currents and charges induced by a driving function on and within a complex scattering object which may be perfectly conducting or a lossy dielectric. This is accomplished by modeling the object with cells within a three-dimensional, rectangular problem space, enforcing the appropriate boundary conditions and differencing Maxwell's equations in time. In the present version of the program, the driving function can be either the field radiated by a lightning strike or a direct lightning strike. The F-106 B aircraft is used as an example scattering object.

Fine-Tuning ADAS Algorithm Parameters for Optimizing Traffic ...

EPA Pesticide Factsheets

With the development of the Connected Vehicle technology that facilitates wirelessly communication among vehicles and road-side infrastructure, the Advanced Driver Assistance Systems (ADAS) can be adopted as an effective tool for accelerating traffic safety and mobility optimization at various highway facilities. To this end, the traffic management centers identify the optimal ADAS algorithm parameter set that enables the maximum improvement of the traffic safety and mobility performance, and broadcast the optimal parameter set wirelessly to individual ADAS-equipped vehicles. After adopting the optimal parameter set, the ADAS-equipped drivers become active agents in the traffic stream that work collectively and consistently to prevent traffic conflicts, lower the intensity of traffic disturbances, and suppress the development of traffic oscillations into heavy traffic jams. Successful implementation of this objective requires the analysis capability of capturing the impact of the ADAS on driving behaviors, and measuring traffic safety and mobility performance under the influence of the ADAS. To address this challenge, this research proposes a synthetic methodology that incorporates the ADAS-affected driving behavior modeling and state-of-the-art microscopic traffic flow modeling into a virtually simulated environment. Building on such an environment, the optimal ADAS algorithm parameter set is identified through an optimization programming framework to enable th

Because of the enormity of the HIV-AIDS epidemic and the urgency for preventing transmission, HIV prevention programs are a high priority for careful and timely evaluations. Information on program effectiveness and efficiency is needed for decision-making about future HIV prevention priorities. General characteristics of successful HIV prevention programs, programs empirically evaluated and found to change (or not change) high-risk behaviors or in need of further empirical study, and economic evaluations of certain programs are described and summarized with attention limited to programs that have a behavioral basis. HIV prevention programs have an impact on averting or reducing risk behaviors, particularly when they are delivered with sufficient resources, intensity, and cultural competency and are based on a firm foundation of behavioral and social science theory and past research. Economic evaluations have found that some of these behaviorally based programs yield net economic benefits to society, and others are likely cost-effective (even if not cost-saving) relative to other health programs. Still, specific improvements should be made in certain HIV prevention programs. PMID:7630989

Effects of Acute Alcohol Tolerance on Perceptions of Danger and Willingness to Drive after Drinking

PubMed Central

Amlung, Michael T.; Morris, David H.; McCarthy, Denis M.

2014-01-01

Rationale Drinking and driving is associated with elevated rates of motor vehicle accidents and fatalities. Previous research suggests that alcohol impairs judgments about the dangers of risky behaviors; however, how alcohol affects driving-related judgments is less clear. Impairments have also been shown to differ across limbs of the blood alcohol concentration (BAC) curve, which is known as acute tolerance. Objectives Examine whether perceptions about the dangerousness of driving after drinking and willingness to drive differed across ascending and descending limbs of the BAC curve. Test whether reductions in perceived danger were associated with willingness to drive on the descending limb. Methods Fifty-six participants were randomly assigned to receive either a moderate dose of alcohol (peak BAC = 0.10 g%) or placebo. We assessed perceived dangerousness and willingness to drive at matched BACs (~0.067-0.068 g%) on the ascending and descending limbs. Results Both perceived danger and willingness to drive showed acute tolerance in the alcohol group. Participants judged driving to be significantly less dangerous and were more willing to drive on the descending limb compared to the ascending limb. The magnitude of change in perceived danger significantly predicted willingness to drive on the descending limb. Conclusions Decreased impairment associated with acute tolerance may lead individuals to underestimate the dangerousness of driving after drinking and in turn make poor decisions regarding driving. This study further emphasizes the descending limb as a period of increased risk and offers support for enhancing prevention efforts by targeting drivers at declining BAC levels. PMID:24752657

Introduction: Eating disorder symptomatology, comprising both psychological and behavioral aspects of subclinical eating concerns, constitutes a clear precursor of developing eating disorders. It is crucial to investigate its antecedents and correlates to subsequently inform eating disorder prevention programs. The present study focused on identity formation, a core developmental task in adolescence, that has increasingly been linked to eating disorder development. Our main aim was to examine the temporal sequence between eating disorder symptomatology and identity formation. Methods: Data on eating disorder symptomatology and identity formation were collected in 530 high school students (at Time 1: mean age = 15 years; SD = 1.84; range: 12-18 years; 50.6% females) using self-report questionnaires at three annual measurement points. Cross-lagged structural equation modeling was performed to examine the directionality of effects. Results: Results indicated bidirectional effects between eating disorder symptomatology and identity formation. Identity confusion seemed to increase vulnerability to body dissatisfaction and bulimia symptoms, whereas identity synthesis seemed to protect against their development. Additionally, identity synthesis seemed to protect against the development of drive for thinness as well. At the same time, body dissatisfaction and bulimia symptoms positively predicted identity confusion and negatively predicted identity synthesis over time. Conclusion: The present study adds to the growing body of literature on identity and eating disorders by focusing on their temporal interplay in a community sample of adolescents. As bidirectional effects emerged, a greater emphasis on identity formation in eating disorder prevention programs is advocated.

Design, implement, and evaluate a 6-week social marketing campaign (SMC) to raise awareness of obesity and increase involvement in type 2 diabetes prevention, nutrition, and fitness programs offered by the Brooklyn Partnership to Drive Down Diabetes (BP3D) in two low-income, urban communities. This was a nonexperimental, formative research, mixed-methods study. The study took place in Central Brooklyn and East New York, two of the most impoverished, high-need communities in New York City. Participants were black and Hispanic adults, who were 18+ years of age and residing in the priority communities. Advertisements in English and Spanish encouraging healthier eating habits and advocating for better food options were displayed on New York City bus shelters, buses, and subway cars operating in the priority communities. Social media, Web sites, and print material were used to promote the campaign message. Social media metrics and a street intercept postsurvey informed the campaign's success. Quantitative data were analyzed using descriptive statistics. One hundred advertisements in English and Spanish were posted. After an 18-month followup, there were over 11,000 visits to the Facebook page. Results from the postsurvey (n = 171) suggest the SMC motivated participants who recognized the advertisements to improve their health behaviors. A multifaceted SMC that coincides with prevention programs can effectively raise attention to health issues and activities in a high-risk population at a relatively low cost. © The Author(s) 2016.

Use of clinical movement screening tests to predict injury in sport

PubMed Central

Chimera, Nicole J; Warren, Meghan

2016-01-01

Clinical movement screening tests are gaining popularity as a means to determine injury risk and to implement training programs to prevent sport injury. While these screens are being used readily in the clinical field, it is only recently that some of these have started to gain attention from a research perspective. This limits applicability and poses questions to the validity, and in some cases the reliability, of the clinical movement tests as they relate to injury prediction, intervention, and prevention. This editorial will review the following clinical movement screening tests: Functional Movement Screen™, Star Excursion Balance Test, Y Balance Test, Drop Jump Screening Test, Landing Error Scoring System, and the Tuck Jump Analysis in regards to test administration, reliability, validity, factors that affect test performance, intervention programs, and usefulness for injury prediction. It is important to review the aforementioned factors for each of these clinical screening tests as this may help clinicians interpret the current body of literature. While each of these screening tests were developed by clinicians based on what appears to be clinical practice, this paper brings to light that this is a need for collaboration between clinicians and researchers to ensure validity of clinically meaningful tests so that they are used appropriately in future clinical practice. Further, this editorial may help to identify where the research is lacking and, thus, drive future research questions in regards to applicability and appropriateness of clinical movement screening tools.

The drive-wise project: driving simulator training increases real driving performance in healthy older drivers

PubMed Central

Casutt, Gianclaudio; Theill, Nathan; Martin, Mike; Keller, Martin; Jäncke, Lutz

2014-01-01

Background: Age-related cognitive decline is often associated with unsafe driving behavior. We hypothesized that 10 active training sessions in a driving simulator increase cognitive and on-road driving performance. In addition, driving simulator training should outperform cognitive training. Methods: Ninety-one healthy active drivers (62–87 years) were randomly assigned to one of three groups: (1) a driving simulator training group, (2) an attention training group (vigilance and selective attention), or (3) a control group. The main outcome variables were on-road driving and cognitive performance. Seventy-seven participants (85%) completed the training and were included in the analyses. Training gains were analyzed using a multiple regression analysis with planned orthogonal comparisons. Results: The driving simulator-training group showed an improvement in on-road driving performance compared to the attention-training group. In addition, both training groups increased cognitive performance compared to the control group. Conclusion: Driving simulator training offers the potential to enhance driving skills in older drivers. Compared to the attention training, the simulator training seems to be a more powerful program for increasing older drivers' safety on the road. PMID:24860497

Driver training interests of a Spanish sample of young drivers and its relationship with their self-assessment skills concerning risky driving behavior.

PubMed

Molina, J Gabriel; Sanmartín, Jaime; Keskinen, Esko

2013-03-01

Poor driving self-assessment skills (e.g., over-confidence) have been pointed out as an important explanatory factor behind young drivers' accident involvement. This paper explores (1) what young drivers miss in their training as drivers in order to analyze whether an assessment of one's own driving skills plays an important role in their desire to improve as drivers, and (2) how these training interests are related to an estimate of their self-assessment skills concerning risky driving behavior. For this purpose, a study was conducted using a survey with a blocked sampling design of novice drivers. The survey solicited respondents' self-report about (1) the contents of training courses that they feel would improve their driving, (2) their risky driving behavior, and (3) their likelihood of being involved in a risky driving situation. From the initial sample invited to participate, of nearly 1300 people, we finally obtained complete data from 321 young Spanish drivers. Two main results were apparent from our data analysis: (1) the novice drivers were mainly interested in improving their ability to recognize their strengths and weaknesses as drivers (i.e., self-assessment skills); (2) a significant relationship was found between novice drivers' interests and their current self-assessment skills concerning risky driving behavior. Specifically, there was greater general interest expressed in post-license training by the under-confident self-assessors than the over-confident ones. These results provide a relevant input which should be taken into account when designing driver training programs for novice drivers. Moreover, the relationship between their training interests and their risky driving self-assessment skills introduces an additional factor to be considered in the implementation of these training programs.

2012-01-01

We performed a retrospective analysis of commercial drivers to clarify the background of incidents of sudden illness while driving. The analysis used reports submitted by employers to the Japan Ministry of Land, Infrastructure, Transport, and Tourism regarding commercial drivers who had been ordered to stop driving owing to health problems. Of 211 cases with an average work history of 15.2 years, there were 88 bus drivers, 70 taxi drivers, and 53 truck drivers, 36.0% of who had died as a result of their disease. Among taxi and truck drivers, more than 70% of incidents were due to cardiac, aortic, and cerebrovascular disease. More than 80% of these were unable to avoid traffic accidents caused by sudden illness. However, among bus drivers, cardiac, aortic, and cerebrovascular disease accounted for only 23.5% of incidents, and accidents were avoided in more than half of the cases. The duration between starting work and the incident time was significantly shorter among bus drivers [mean 3.3 hours, standard deviation (SD) 3.1] than taxi (7.7 hours, SD 5.8) and truck (7.2 hours, SD 6.3) drivers (P<0.01). The difference between the sudden illness rates of taxi and truck drivers and those of bus drivers is due to both reporting bias and differences in the awareness needed to prevent disabling events while driving. As a precaution, physicians should advise commercial drivers to stop driving as soon as they detect slight discomfort. To prevent accidents, more assertive health promotion aimed at professional drivers is needed.

Background Recognition of the risks associated with alcohol intoxication and driver distraction has led to a wealth of simulated driving research aimed at studying the adverse effects of each of these factors. Research on driving has moved beyond the individual, separate examination of these factors to the examination of potential interactions between alcohol intoxication and driver distraction. In many driving situations, distractions are commonplace and might have little or no disruptive influence on primary driving functions. Yet, such distractions might become disruptive to a driver who is intoxicated. Methods The present study examined the interactive impairing effects of alcohol intoxication and driver distraction on simulated driving performance in 40 young adult drivers using a divided attention task as a distracter activity. The interactive influence of alcohol and distraction was tested by having drivers perform the driving task under four different conditions: 0.65 g/kg alcohol; 0.65 g/kg alcohol + divided attention; placebo; and placebo + divided attention. Results As hypothesized, divided attention had no impairing effect on driving performance in sober drivers. However, under alcohol, divided attention exacerbated the impairing effects of alcohol on driving precision. Conclusions Alcohol and distraction continue to be appropriate targets for research into ways to reduce the rates of driving-related fatalities and injuries. Greater consideration of how alcohol and distraction interact to impair aspects of driving performance can further efforts to create prevention and intervention measures to protect drivers, particularly young adults.

To review the characteristics and effects Internet-based youth smoking prevention and cessation programs. Systematic review of published articles in peer-reviewed journals in the past 10 years, focused on Internet-based youth smoking prevention and cessation programs. Twelve articles were selected based on the following criteria: studies reporting the outcomes of Internet-based smoking cessation or prevention intervention programs for adolescents who are younger than 24 years. The components of youth Internet-based smoking intervention programs are analyzed based on study features (i.e., sample, design, theoretical basis, analysis, outcome measures) and program characteristics (i.e., focus, setting, frequency, duration, intensity, and different components) that make the programs effective. The most common components of effective Internet-based programs are identified as the following: the use of multimedia, tailored approaches, personalized feedback, and interactive features. The characteristics and effects of the programs vary, but most programs show positive results in youth smoking prevention and cessation in spite of the studies' limitations. The evidence from this review provides useful information of recent efforts related to Internet-based youth smoking prevention and cessation programs, which can have significant clinical implications in developing future innovative youth smoking prevention and intervention programs. © 2014 Sigma Theta Tau International.

Indigenous young people have significantly higher suicide rates than their non-indigenous counterparts. There is a need for culturally appropriate and effective suicide prevention programs for this demographic. This review assesses suicide prevention programs that have been evaluated for indigenous youth in Australia, Canada, New Zealand, and the United States. The databases MEDLINE and PsycINFO were searched for publications on suicide prevention programs targeting indigenous youth that include reports on evaluations and outcomes. Program content, indigenous involvement, evaluation design, program implementation, and outcomes were assessed for each article. The search yielded 229 articles; 90 abstracts were assessed, and 11 articles describing nine programs were reviewed. Two Australian programs and seven American programs were included. Programs were culturally tailored, flexible, and incorporated multiple-levels of prevention. No randomized controlled trials were found, and many programs employed ad hoc evaluations, poor program description, and no process evaluation. Despite culturally appropriate content, the results of the review indicate that more controlled study designs using planned evaluations and valid outcome measures are needed in research on indigenous youth suicide prevention. Such changes may positively influence the future of research on indigenous youth suicide prevention as the outcomes and efficacy will be more reliable.

The prevalence of obesity in rural and remote areas is elevated in comparison to urban populations, highlighting the need for interventions targeting obesity prevention in these settings. Implementing evidence-based obesity prevention programs is challenging. This study aimed to investigate factors influencing the implementation of obesity prevention programs, including adoption, program delivery, community uptake, and continuation, specifically within rural settings. Nested within a large-scale randomized controlled trial, a qualitative exploratory approach was adopted, with purposive sampling techniques utilized, to recruit stakeholders from 41 small rural towns in Australia. In-depth semistructured interviews were conducted with clinical health professionals, health service managers, and local government employees. Open coding was completed independently by 2 investigators and thematic analysis undertaken. In-depth interviews revealed that obesity prevention programs were valued by the rural workforce. Program implementation is influenced by interrelated factors across: (1) contextual factors and (2) organizational capacity. Key recommendations to manage the challenges of implementing evidence-based programs focused on reducing program delivery costs, aided by the provision of a suite of implementation and evaluation resources. Informing the scale-up of future prevention programs, stakeholders highlighted the need to build local rural capacity through developing supportive university partnerships, generating local program ownership and promoting active feedback to all program partners. We demonstrate that the rural workforce places a high value on obesity prevention programs. Our results inform the future scale-up of obesity prevention programs, providing an improved understanding of strategies to optimize implementation of evidence-based prevention programs. © 2015 National Rural Health Association.

In the present study, we investigated gender-related effects on road safety attitudes in 2681 young drivers (1458 males, 54.4%; aged 18–22) who filled out several scales assessing attitudes toward road safety issues, driving behavior in specific hypothetical situations, accident risk perception, and concerns about such a risk. We focused only on young drivers to better understand the role of gender in road safety attitudes in a period of life in which risky behaviors are widespread for males and females. Indeed, there is still no agreement as to the nature of these gender differences. According to some authors, the effects of gender on being involved in a crash due to driving skills are either non-existent or largely explained by differences in alcohol consumption. In our study, we found gender differences in road safety attitudes (i.e., “negative attitude toward traffic rules and risky driving”; “negative attitude toward drugs and alcohol” and “tolerance toward speeding”) and in driver behavior (i.e., “errors in inattentive driving” and “driving violations”). This result is consistent in all drivers coming from nine different European countries. Our analyses yielded an important finding concerning risk perception. The results indicate that the level of risk perception during driving is the same for males and females. However, these two groups differ in the level of concern about this risk, with males being less concerned about the risk of a road accident. This suggests that the main difference between these two groups is not strictly related to judgment of the perceived risk probability but rather to the level of concern experienced about the consequences of the risk. This difference between risk perception and worry could explain differences in the frequency of car accidents in the two groups. The present findings may provide new insights for the development of gender-based prevention programs. PMID:27729877

A novel driving method for two-dimensional (2D) and three-dimensional (3D) switchable active matrix organic light-emitting diode (AMOLED) displays is proposed to extend emission time and data programming time during 3D display operation. The proposed pixel consists of six thin-film transistors (TFTs) and two capacitors, and the aperture ratio of the pixel is 45.8% under 40-in. full-high-definition television condition. By increasing emission time and programming time, the flicker problem can be reduced and the lifetime of AMOLED displays can be extended owing to the decrease in emission current density. Simulation results show that the emission current error range from -0.4 to 1.6% is achieved when the threshold voltage variation of driving TFTs is in the range from -1.0 to 1.0 V, and the emission current error is 1.0% when the power line IR-drop is 2.0 V.
