Objective To determine the impact of personality on distracted driving behaviors. Method Participants included 120 drivers (48 teens, 72 older adults) who completed the 45-item Big Five Personality questionnaire assessing self-reported personality factors and the Questionnaire Assessing Distracted Driving (QUADD) assessing the frequency of distracted driving behaviors. Associations for all five personality traits with each outcome (e.g. number of times texting on the phone, talking on the phone, and interacting with the phone while driving) were analyzed separately for teens and older adults using negative binomial or Poisson regressions that controlled for age, gender and education. Results In teens, higher levels of openness and conscientiousness were predictive of greater reported texting frequency and interacting with a phone while driving, while lower levels of agreeableness was predictive of fewer reported instances of texting and interacting with a phone while driving. In older adults, greater extraversion was predictive of greater reported talking on and interacting with a phone while driving. Other personality factors were not significantly associated with distracted driving behaviors. Conclusions Personality traits may be important predictors of distracted driving behaviors, though specific traits associated with distracted driving may vary across age groups. The relationship between personality and distracted driving behaviors provides a unique opportunity to target drivers who are more likely to engage in distracted driving behavior, thereby increasing the effectiveness of educational campaigns and improving driving safety.

Purpose This study was designed to examine the on-road driving performance of drivers with hemianopia and quadrantanopia compared with age-matched controls. Methods Participants included persons with hemianopia or quadrantanopia and those with normal visual fields. Visual and cognitive function tests were administered, including confirmation of hemianopia and quadrantanopia through visual field testing. Driving performance was assessed using a dual-brake vehicle and monitored by a certified driving rehabilitation specialist. The route was 14.1 miles of city and interstate driving. Two “back-seat” evaluators masked to drivers’ clinical characteristics independently assessed driving performance using a standard scoring system. Results Participants were 22 persons with hemianopia and 8 with quadrantanopia (mean age, 53 ± 20 years) and 30 participants with normal fields (mean age, 52 ± 19 years). Inter-rater agreement for back-seat evaluators was 96%. All drivers with normal fields were rated as safe to drive, while 73% (16/22) of hemianopic and 88% (7/8) of quadrantanopic drivers received safe ratings. Drivers with hemianopia or quadrantanopia who displayed on-road performance problems tended to have difficulty with lane position, steering steadiness, and gap judgment compared to controls. Clinical characteristics associated with unsafe driving were slowed visual processing speed, reduced contrast sensitivity and visual field sensitivity. Conclusions Some drivers with hemianopia or quadrantanopia are fit to drive compared with age-matched control drivers. Results call into question the fairness of governmental policies that categorically deny licensure to persons with hemianopia or quadrantanopia without the opportunity for on-road evaluation.

Individual differences in morningness-eveningness preference may influence susceptibility and response to sleepiness. These differences could influence driving performance, but the influence of morningness-eveningness preference on driving behavior and accident risk has not been comprehensively studied. As morningness-eveningness preference is associated with personality characteristics, we also investigated how the interaction between morningness-eveningness preference and personality may be related to dangerous driving behaviors. Two hundred and ninety five drivers completed the reduced Morningness-Eveningness Questionnaire, the Dula Dangerous Driving Index, and personality scales for agreeableness, conscientiousness and neuroticism, and reported demographic information (gender, age, level of education, driving years and annual average driving mileage) and self-reported traffic violations (accidents, penalty points and fines). The results showed that more Risky Driving, Aggressive Driving, Negative Cognitive/Emotional Driving and Drunk Driving, as measured by the Dula Dangerous Driving Index, were all significantly correlated with more eveningness, corresponding to lower scores on the reduced Morningness-Eveningness Questionnaire. Moreover, eveningness was correlated with self-reported traffic accidents, penalty points and fines. Furthermore, a moderation effect was found: eveningness was more strongly associated with risky driving and negative emotional driving in those who scored high for trait agreeableness. PMID:25615447

As part of the effort to ascertain why young drivers are more at risk for car crashes, attention has recently turned to the effects of family, including the intergenerational transmission of driving styles from parents to offspring. The current study sought to further understanding of the nature and aspects of the family influence with the help of Bowen's family systems theory. In Phase 1 of the prospective study, 130 young driving students completed questionnaires tapping personal and personality measures, and their parents completed driving-related instruments. In Phase 2, a year after the young drivers had obtained their driver's license, they were administered the same questionnaires their parents had previously completed. The results show significant correlations between the parents' driving styles and those of their offspring a year after licensure. Furthermore, differentiation of self and self-efficacy in newly acquired driving skills were found to moderate or heighten the similarity between the driving styles of parents and their offspring. For young drivers reporting anxiety in Phase 1, this was associated with a reported anxious driving style a year later. Among young female drivers, anxiety was also associated with a reckless and careless style. Higher sensation seeking was related to higher reckless driving among young male drivers. The findings are discussed in the context of adolescence and the role of the study variables in the development and intergenerational transmission of driving styles. In addition to its theoretical contribution to the realms of intergenerational transmission in general, and young drivers in particular, the study may have practical implications for both family therapy and the design of driving interventions.

This study explored the impact of personality traits on driving safety in high-speed railway drivers. A sample of high-speed railway drivers in Beijing (N=214) completed a questionnaire, including information on personality traits and background variables. The NEO Five Factor Inventory (NEO-FFI) was administered to characterize participants based on five personality traits: Neuroticism, Extraversion, Agreeableness, Openness to Experience, and Conscientiousness. The survey data were combined with naturalistic data of accident involvement and risky driving behavior in China. Poisson regression results show that drivers with high Conscientiousness and Extraversion caused fewer accidents. Higher Conscientiousness and lower Agreeableness were related to less frequent risky driving behavior. Education level and age negatively moderated the relation between certain personality traits and driving safety. The findings suggest that personality traits should be considered when selecting and training high-speed railway drivers. Copyright © 2016 Elsevier Ltd. All rights reserved.

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

The big five personality factors as predictors of driving status in older adults.

Gadbois, Emily A; Dugan, Elizabeth

2015-02-01

Although factors including cognitive and health status have been associated with driving cessation in older adults, the role of psychosocial variables is not well studied. Previous research on young adult drivers has suggested that personality may be related to driving behavior, but this study is among the first to explore the relationship between driving status and the Big Five Model of personality for older adults. Data are from the Health and Retirement Study (2008 wave, n = 4,028). Descriptive, bivariate, and multiple logistic regression analyses were conducted. Neuroticism (β = -0.4511, p < .001) and agreeableness (β = -0.5058, p < .001) were associated with decreased likelihood of driving; extraversion (β = 0.4588, p < .001), openness (β = 0.5903, p < .001), and conscientiousness (β = 0.4077, p < .001) were associated with increased likelihood of driving, although results were partially mediated by including known risk factors. People who limited their driving to nearby locations were the most different from those who no longer drove. Personality adds a unique contribution to the prediction of late-life driving status. © The Author(s) 2014.

Examining How Media Literacy and Personality Factors Predict Skepticism Toward Alcohol Advertising.

Austin, Erica Weintraub; Muldrow, Adrienne; Austin, Bruce W

2016-05-01

To examine the potential effectiveness of media literacy education in the context of well-established personality factors, a survey of 472 young adults, focused on the issue of alcohol marketing messages, examined how individual differences in personality associate with constructs representing aspects of media literacy. The results showed that need for cognition predicted social expectancies and wishful identification with media portrayals in alcohol advertising only through critical thinking about media sources and media content, which are foci of media literacy education. Need for affect did not associate with increased or diminished levels of critical thinking. Critical thinking about sources and messages affected skepticism, represented by expectancies through wishful identification, consistent with the message interpretation process model. The results support the view that critical thinking about media sources is an important precursor to critical thinking about media messages. The results also suggest that critical thinking about media (i.e., media literacy) reflects more than personality characteristics and can affect wishful identification with role models observed in media, which appears to be a key influence on decision making. This adds support to the view that media literacy education can improve decision making across personality types regarding alcohol use by decreasing the potential influence of alcohol marketing messages.

This research evaluated the efficacy of a high-intensity social norms media marketing campaign aimed at correcting normative misperceptions and reducing the prevalence of drinking and driving among 21-to-34-year-olds in Montana. A quasi-experimental design was used, such that regions of Montana were assigned to one of three experimental groups: social norms media marketing campaign, buffer, and control. Four random samples of Montanans between the ages of 21 and 34 were assessed at four time points over 18 months via phone surveys. Findings suggest that the social norms media campaign was successful at exposing the targeted population to social norms messages in the counties within the intervention region. Moreover, results demonstrate the campaign reduced normative misperceptions, increased use of designated drivers, and decreased drinking and driving among those young adults in counties within the intervention region. Social norms media marketing can be effective at changing drinking-related behaviors at the population level. This research provides a model for utilizing social norms media marketing to address other behaviors related to public health. 2010 Elsevier Ltd. All rights reserved.

The aim of the work was the analysis of personality traits of men serving a custodial sentence for driving under the influence of alcohol. The study included 44 males serving a custodial sentence for drink driving, 45 males serving a custodial sentence for assault and robbery as well as 32 men with no criminal record, who had never driven a motor vehicle under the influence of alcohol. The following research methods were used during the study: the Socio-demographic Questionnaire designed by the authors, the KRS, the Cattell's IPAT, the NI, the ACL and the Life style Questionnaire. The obtained results indicate significant statistical differences between the men serving the custodial sentence for drink driving as regards stress coping, anxiety level, intensified need to look for new experiences as well as anti-social personality traits. The men serving a custodial sentence for drink driving show intensified traits of antisocial personality, higher level of anxiety, intensified impulsiveness irritability, distrust, aggression, egocentrism, eccentricity, intensified need for recognition, breaking social standards, experiencing various stimuli, new impressions, greater adaptation difficulties, less self-discipline, lower self-esteem as well as more frequently used destructive, escapist and emotional stress coping strategies as compared to the people with no criminal record, who never drove while under the influence of alcohol. As regards the intensity of personality disorders, stress coping strategies and self-image no significant differences were found between the men serving a custodial sentence for drink driving and those imprisoned for assault and robbery.

An Evaluation of Personal Health Information Remnants in Second-Hand Personal Computer Disk Drives

2007-01-01

Background The public is concerned about the privacy of their health information, especially as more of it is collected, stored, and exchanged electronically. But we do not know the extent of leakage of personal health information (PHI) from data custodians. One form of data leakage is through computer equipment that is sold, donated, lost, or stolen from health care facilities or individuals who work at these facilities. Previous studies have shown that it is possible to get sensitive personal information (PI) from second-hand disk drives. However, there have been no studies investigating the leakage of PHI in this way. Objectives The aim of the study was to determine the extent to which PHI can be obtained from second-hand computer disk drives. Methods A list of Canadian vendors selling second-hand computer equipment was constructed, and we systematically went through the shuffled list and attempted to purchase used disk drives from the vendors. Sixty functional disk drives were purchased and analyzed for data remnants containing PHI using computer forensic tools. Results It was possible to recover PI from 65% (95% CI: 52%-76%) of the drives. In total, 10% (95% CI: 5%-20%) had PHI on people other than the owner(s) of the drive, and 8% (95% CI: 7%-24%) had PHI on the owner(s) of the drive. Some of the PHI included very sensitive mental health information on a large number of people. Conclusions There is a strong need for health care data custodians to either encrypt all computers that can hold PHI on their clients or patients, including those used by employees and subcontractors in their homes, or to ensure that their computers are destroyed rather than finding a second life in the used computer market.

Perpendicular recording media for hard disk drives

NASA Astrophysics Data System (ADS)

Piramanayagam, S. N.

2007-07-01

Perpendicular recording technology has recently been introduced in hard disk drives for computer and consumer electronics applications. Although conceptualized in the late 1970s, making a product with perpendicular recording that has competing performance, reliability, and price advantage over the prevalent longitudinal recording technology has taken about three decades. One reason for the late entry of perpendicular recording is that the longitudinal recording technology was quite successful in overcoming many of its problems and in staying competitive. Other reasons are the risks, problems, and investment needed in making a successful transition to perpendicular recording technology. Iwasaki and co-workers came up with many inventions in the late 1970s, such as single-pole head, CoCr alloy media with a perpendicular anisotropy, and recording media with soft magnetic underlayers [S. Iwasaki and K. Takemura, IEEE Trans. Magn. 11, 1173 (1975); S. Iwasaki and Y. Nakamura, IEEE Trans. Magn. 14, 436 (1978); S. Iwasaki, Y. Nakamura, and K. Ouchi, IEEE Trans. Magn. 15, 1456 (1979)]. Nevertheless, the research on perpendicular recording media has been intense only in the past five years or so. The main reason for the current interest comes from the need to find an alternative technology to get away from the superparamagnetic limit faced by the longitudinal recording. Out of the several recording media materials investigated in the past, oxide based CoCrPt media have been considered a blessing. The media developed with CoCrPt-oxide or CoCrPt -SiO2 have shown much smaller grain sizes, lower noise, and larger thermal stability than the perpendicular recording media of the past, which is one of the reasons for the success of perpendicular recording. Moreover, oxide-based perpendicular media have also overtaken the current longitudinal recording media in terms of better recording performance. Several issues that were faced with the soft underlayers have also been solved by the

Three psychiatrist authors illustrate the impact of social media on their professional lives by reflecting on personal stories about their experiences with social media. They reflect on their experiences with listservs, chat rooms, online forums, blogs, podcasts, and other interactive media, while recounting actual stories involving those media. The impact of social media on professional advocacy across broad populations is addressed. In addition, the use of social media in educating psychiatric trainees and informing forensic evaluations is discussed. Finally, social media as a tool for enhancing consumer advocacy and addressing controversial patient safety procedures in emergency settings is discussed.

Recruiting adolescent participants for research is challenging. The purpose of this study was to compare traditional in-person recruitment methods to social media recruitment. We recruited adolescents aged 14-18 years for a pilot physical activity intervention study, including a wearable physical activity tracking device and a Facebook group. Participants were recruited (a) in person from a local high school and an adolescent medicine clinic and (b) through social media, including Facebook targeted ads, sponsored tweets on Twitter, and a blog post. Data collected included total exposure (i.e., reach), engagement (i.e., interaction), and effectiveness. Effectiveness included screening and enrollment for each recruitment method, as well as time and resources spent on each recruitment method. In-person recruitment reached a total of 297 potential participants of which 37 enrolled in the study. Social media recruitment reached a total of 34,272 potential participants of which 8 enrolled in the study. Social media recruitment methods utilized an average of 1.6 hours of staff time and cost an average of $40.99 per participant enrolled, while in-person recruitment methods utilized an average of 0.75 hours of staff time and cost an average of $19.09 per participant enrolled. Social media recruitment reached more potential participants, but the cost per participant enrolled was higher compared to traditional methods. Studies need to consider benefits and downsides of traditional and social media recruitment methods based on study goals and population.

To investigate whether driving performance is impaired in persons with mild to moderate multiple sclerosis (MS). This study included 15 persons with MS (pwMS) and 17 healthy controls. The MS group exhibited mild to moderate impairments on the Expanded Disability Status Scale (median, Q1-Q3; 3.5, 2.5-4). The driving simulation required participants to drive in daily traffic while attending to a divided attention (DA) task. Computerized measures on the driving task included number of accidents, tickets, speed maintenance, standard deviation of lateral position, and time to collision. Response times and accuracy on the DA task were also computer generated. Additionally, pwMS completed a clinical evaluation encompassing motor, functional, visual, psychosocial and cognitive tests. No differences between healthy controls and pwMS were observed on all measures of the primary driving task. PwMS performed worse than healthy controls on DA response time (3.10 s, 2.87-3.68 versus 2.15 s, 2.04-2.43; p = 0.001) and accuracy (15 correct answers, 11-18 versus 24 correct answers, 22-25; p < 0.0001). Depression was significantly associated with time to collision (r = -0.77; p < 0.01). Subjects with mild to moderate MS are able to prioritize the driving task above the DA task. The relationship between depression and driving performance in MS merits further investigation.

Crash risk and aberrant driving behaviors among bus drivers: the role of personality and attitudes towards traffic safety.

Several studies have shown that personality traits and attitudes toward traffic safety predict aberrant driving behaviors and crash involvement. However, this process has not been adequately investigated in professional drivers, such as bus drivers. The present study used a personality-attitudes model to assess whether personality traits predicted aberrant self-reported driving behaviors (driving violations, lapses, and errors) both directly and indirectly, through the effects of attitudes towards traffic safety in a large sample of bus drivers. Additionally, the relationship between aberrant self-reported driving behaviors and crash risk was also assessed. Three hundred and one bus drivers (mean age=39.1, SD=10.7 years) completed a structured and anonymous questionnaire measuring personality traits, attitudes toward traffic safety, self-reported aberrant driving behaviors (i.e., errors, lapses, and traffic violations), and accident risk in the last 12 months. Structural equation modeling analysis revealed that personality traits were associated to aberrant driving behaviors both directly and indirectly. In particular altruism, excitement seeking, and normlessness directly predicted bus drivers' attitudes toward traffic safety which, in turn, were negatively associated with the three types of self-reported aberrant driving behaviors. Personality traits relevant to emotionality directly predicted bus drivers' aberrant driving behaviors, without any mediation of attitudes. Finally, only self-reported violations were related to bus drivers' accident risk. The present findings suggest that the hypothesized personality-attitudes model accounts for aberrant driving behaviors in bus drivers, and provide the empirical basis for evidence-based road safety interventions in the context of public transport.

2014-12-01

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.

Drunk driving is one of the major behavioral issues connected with problematic alcohol consumption. The objective of this study was to evaluate the relationship between personality traits and social problem-solving skills of individuals who drive while intoxicated. One hundred forty-four individuals apprehended twice while driving drunk and sent to a driver behavior training program (9 females and 135 males) participated in our study. The Eysenck Personality Questionnaire Revised-Abbreviated (EPQ-RA) composed of 4 subscales (Extroversion, Neuroticism, Psychoticism, and Lying) and the Social Problem Solving Inventory (SPSI) composed of 7 subscales (Cognitive, Emotion, Behavior, Problem Definition and Formulation, Creating Solution Options, Solution Implementation and Verification, and Decision Making) were used to evaluate the participants. A positive relationship was found between the Extroversion subscale of the EPQ-RA and the Cognition subscale (P <.01), Emotion subscale (P <.01), Behavior subscale (P <.01), Generation of Alternatives subscale (P <.01), Decision Making subscale (P <.05), and Solution Implementation and Verification subscale (P <.01). For individuals who repeated intoxicated driving, all subscales of the EPQ-RA (Extroversion, Lying, Neuroticism, and Psychoticism subscales) explained 12% of the scores of the Cognition subscale and 16.2% (P <.001) of the Emotion subscale of the SPSI. There was no significant relationship between the first and second incident alcohol blood levels (P >.05). Drinking and driving behaviors appear to be negative or maladaptive behaviors closely related to personality traits and may represent an effort to avoid negative emotions. Evaluation of negative emotions may have an important place in training programs intended to change drunk driving behavior.

Job applicants and incumbents often use social media for personal communications allowing for direct observation of their social communications "unfiltered" for employer consumption. As such, these data offer a glimpse of employees in settings free from the impression management pressures present during evaluations conducted for applicant screening and research purposes. This study investigated whether job applicants' (N=175) personality characteristics are reflected in the content of their social media postings. Participant self-reported social media content related to (a) photos and text-based references to alcohol and drug use and (b) criticisms of superiors and peers (so-called "badmouthing" behavior) were compared to traditional personality assessments. Results indicated that extraverted candidates were prone to postings related to alcohol and drugs. Those low in agreeableness were particularly likely to engage in online badmouthing behaviors. Evidence concerning the relationships between conscientiousness and the outcomes of interest was mixed.

Th9, switched reluctance motor (SRM) has recently gained considerable attention in the variable speed drive market. Two important factors that have contributed to this are, the simplicity of construction and the possibility of developing low cost con-trollers with minimum number of switching devices in the drive circuits. This is mainly due to the state-of-art of the present digital circuits technology and the low cost of switching devices. The control of this motor drive is under research. Optimized performance of the SRM motor drive is very dependent on the integration of the controller, converter and the motor. This research on system integration involves considerable changes in the control algorithms and their implementation. A Personal computer (PC) based controller is very appropriate for this purpose. Accordingly, the present paper is concerned with the design of a PC based controller for a SRM. The PC allows for real-time microprocessor control with the possibility of on-line system parameter modifications. Software reconfiguration of this controller is easier than a hardware based controller. User friendliness is a natural consequence of such a system. Considering the low cost of PCs, this controller will offer an excellent cost-effective means of studying the control strategies for the SRM drive intop greater detail than in the past.

To study the effect on quality of life (QOL) of a seizure attack while driving in persons with epilepsy (PWE). From four provincial and eight university hospitals in Thailand, we enrolled epileptic patients who drove a car or motorcycle or used to drive. The SF-36 questionnaire was used to evaluate QOL. The mean SF-36 score for all dimensions was calculated and compared with patients who either had or did not have a seizure attack while driving and in those who either had or had not been involved in a traffic accident while driving. We had 245 adult PWE who drove a car or motorcycle or used to drive. Of these, 69 cases (28%) had a seizure attack whilst driving. Over half (36/69; 57%) had had seizure-related accidents, most of which were mild but about 20% needed hospitalization. PWE having a seizure attack while driving had a significantly lower QOL in four of the eight categories compared with patients who had not. PWE who had a seizure-related accident had a significantly lower mean value in the vitality category than those who did not. Seizure attacks while driving diminished QOL in PWE even though they only suffered minor injuries. Driving as a QOL issue should be discussed with patients. A good public transportation system would ease the need to drive.

Language use is a psychologically rich, stable individual difference with well-established correlations to personality. We describe a method for assessing personality using an open-vocabulary analysis of language from social media. We compiled the written language from 66,732 Facebook users and their questionnaire-based self-reported Big Five personality traits, and then we built a predictive model of personality based on their language. We used this model to predict the 5 personality factors in a separate sample of 4,824 Facebook users, examining (a) convergence with self-reports of personality at the domain- and facet-level; (b) discriminant validity between predictions of distinct traits; (c) agreement with informant reports of personality; (d) patterns of correlations with external criteria (e.g., number of friends, political attitudes, impulsiveness); and (e) test-retest reliability over 6-month intervals. Results indicated that language-based assessments can constitute valid personality measures: they agreed with self-reports and informant reports of personality, added incremental validity over informant reports, adequately discriminated between traits, exhibited patterns of correlations with external criteria similar to those found with self-reported personality, and were stable over 6-month intervals. Analysis of predictive language can provide rich portraits of the mental life associated with traits. This approach can complement and extend traditional methods, providing researchers with an additional measure that can quickly and cheaply assess large groups of participants with minimal burden.

Cognitive impairment is common in multiple sclerosis (MS). In other populations, cognitive impairment is known to affect fitness-to-drive. Few studies have focused on fitness-to-drive in MS and no studies have solely focused on the influence of cognitive impairment. To assess fitness-to-drive in persons with MS with cognitive impairment and low physical disability. Persons with MS, aged 18-59 years with EDSS ⩽ 4.0, impaired processing speed, and impairment on at least one measure of memory or executive function, were recruited. Cognition was assessed using the Minimal Assessment of Cognitive Function battery. A formal on-road driving assessment was conducted. Chi-square analysis examined the association between the fitness-to-drive (pass/fail) and the neuropsychological test results (normal/impaired). Bayesian statistics predicting failure of the on-road assessment were calculated. Of 36 subjects, eight (22.2%) were unfit to drive. Only the BVMTR-IR, measuring visual-spatial memory, predicted on-road driving assessment failure ( X 2 ( df = 1, N = 36) = 3.956; p = 0.047) with a sensitivity of 100%, but low specificity (35.7%) due to false positives (18/25). In persons with MS and impaired processing speed, impairment on the BVMTR-IR should lead clinicians to address fitness-to-drive.

Cross sectional study. To determine the prevalence, characteristics of and barriers to driving among persons with a spinal cord injury (SCI). SCI Rehabilitation Clinic, University Malaya Medical Centre (UMMC). This is a questionnaire-based study on persons with SCI who attended the UMMC SCI Rehabilitation Clinic between June 2015 and November 2016. The questionnaire comprised demographic data, clinical characteristics, driving variables, Spinal Cord Independence Measure III, WHOQOL-BREF, and Craig Handicap Assessment and Reporting Technique Short Form. Malaysians aged greater than 18 years old with any etiology and levels of SCI, had no other physical disabilities and not suffering from progressive illness were recruited. A single investigator administered the questionnaire via face-to-face interviews. A total of 160 participants were included in this study. Overall, 37% of persons with SCI drove and owned a modified vehicle. Almost half of persons with paraplegia (47%) drove, but only 12% of tetraplegia did. A majority (93%) of those who drove aged below 60 years, and had higher level of independence in activity of daily living. More drivers (81%) compared to non-drivers (24%) were employed; drivers also reported better community reintegration and quality of life. Three commonest barriers to driving included medical reasons (38%), fear and lack of confidence (17%), and inability to afford vehicle modifications (13%). The percentage of persons with SCI driving post injury is low. Based on the findings of this study, more efforts are needed to motivate and facilitate persons with SCI to drive.

Optimizing digital 8mm drive performance

Schadegg, Gerry

1993-01-01

The experience of attaching over 350,000 digital 8mm drives to 85-plus system platforms has uncovered many factors which can reduce cartridge capacity or drive throughput, reduce reliability, affect cartridge archivability and actually shorten drive life. Some are unique to an installation. Others result from how the system is set up to talk to the drive. Many stem from how applications use the drive, the work load that's present, the kind of media used and, very important, the kind of cleaning program in place. Digital 8mm drives record data at densities that rival those of disk technology. Even with technology this advanced, they are extremely robust and, given proper usage, care and media, should reward the user with a long productive life. The 8mm drive will give its best performance using high-quality 'data grade' media. Even though it costs more, good 'data grade' media can sustain the reliability and rigorous needs of a data storage environment and, with proper care, give users an archival life of 30 years or more. Various factors, taken individually, may not necessarily produce performance or reliability problems. Taken in combination, their effects can compound, resulting in rapid reductions in a drive's serviceable life, cartridge capacity, or drive performance. The key to managing media is determining the importance one places upon their recorded data and, subsequently, setting media usage guidelines that can deliver data reliability. Various options one can implement to optimize digital 8mm drive performance are explored.

Cloud-based storage and consumption of personal photos and videos provides increased accessibility, functionality, and satisfaction for mobile users. One cloud service frontier that is recently growing is that of personal media management. This work presents a system called VidCat that assists users in the tagging, organization, and retrieval of their personal media by faces and visual content similarity, time, and date information. Evaluations for the effectiveness of the copy detection and face recognition algorithms on standard datasets are also discussed. Finally, the system includes a set of application programming interfaces (API's) allowing content to be uploaded, analyzed, and retrieved on any client with simple HTTP-based methods as demonstrated with a prototype developed on the iOS and Android mobile platforms.

Influenza A virus (IAV) predisposes individuals to secondary infections with the bacterium Streptococcus pneumoniae (the pneumococcus). Infections may manifest as pneumonia, sepsis, meningitis, or otitis media (OM). It remains controversial as to whether secondary pneumococcal disease is due to the induction of an aberrant immune response or IAV-induced immunosuppression. Moreover, as the majority of studies have been performed in the context of pneumococcal pneumonia, it remains unclear how far these findings can be extrapolated to other pneumococcal disease phenotypes such as OM. Here, we used an infant mouse model, human middle ear epithelial cells, and a series of reverse-engineered influenza viruses to investigate how IAV promotes bacterial OM. Our data suggest that the influenza virus HA facilitates disease by inducing a proinflammatory response in the middle ear cavity in a replication-dependent manner. Importantly, our findings suggest that it is the inflammatory response to IAV infection that mediates pneumococcal replication. This study thus provides the first evidence that inflammation drives pneumococcal replication in the middle ear cavity, which may have important implications for the treatment of pneumococcal OM.

2015-01-01

Assessing the driving abilities of individuals with disabilities is often a very challenging task because each medical condition is accompanied by physical impairments and because relative individual functional performance may vary depending on personal characteristics. We identified existing driving evaluation modalities for able-bodied and lower extremity-impaired subjects (spinal cord injury patients and amputees) and evaluated the potential relationships between driving performance and the motor component of driving. An extensive scoping review of the literature was conducted to identify driving assessment tools that are currently used for able-bodied individuals and for those with spinal cord injury or lower extremity amputation. The literature search focused on the assessment of the motor component of driving. References were electronically obtained via Medline from the PubMed, Ovid, Web of Science and Google Scholar databases. This article compares the current assessments of driving performance for those with lower extremity impairments with the assessments used for able-bodied persons. Very few articles were found concerning “Lower Extremity Disabilities,” thus confirming the need for further studies that can provide evidence and guidance for such assessments in the future. Little is known about the motor component of driving and its association with the other driving domains, such as vision and cognition. The available research demonstrates the need for a more evidenced-based understanding of how to best evaluate persons with lower extremity impairment. PMID:26375567

A multi-label, semi-supervised classification approach applied to personality prediction in social media.

PubMed

Lima, Ana Carolina E S; de Castro, Leandro Nunes

2014-10-01

Social media allow web users to create and share content pertaining to different subjects, exposing their activities, opinions, feelings and thoughts. In this context, online social media has attracted the interest of data scientists seeking to understand behaviours and trends, whilst collecting statistics for social sites. One potential application for these data is personality prediction, which aims to understand a user's behaviour within social media. Traditional personality prediction relies on users' profiles, their status updates, the messages they post, etc. Here, a personality prediction system for social media data is introduced that differs from most approaches in the literature, in that it works with groups of texts, instead of single texts, and does not take users' profiles into account. Also, the proposed approach extracts meta-attributes from texts and does not work directly with the content of the messages. The set of possible personality traits is taken from the Big Five model and allows the problem to be characterised as a multi-label classification task. The problem is then transformed into a set of five binary classification problems and solved by means of a semi-supervised learning approach, due to the difficulty in annotating the massive amounts of data generated in social media. In our implementation, the proposed system was trained with three well-known machine-learning algorithms, namely a Naïve Bayes classifier, a Support Vector Machine, and a Multilayer Perceptron neural network. The system was applied to predict the personality of Tweets taken from three datasets available in the literature, and resulted in an approximately 83% accurate prediction, with some of the personality traits presenting better individual classification rates than others.

Leykin, Dmitry; Aharonson-Daniel, Limor; Lahad, Mooli

2016-03-24

The extensive use of social media in modern life redefines social interaction and communication. Communication plays an important role in mitigating, or exacerbating, the psychological and behavioral responses to critical incidents and disasters. As recent disasters demonstrated, people tend to converge to social media during and following emergencies. Authorities can then use this media and other computational methods to gain insights from the public, mainly to enhance situational awareness, but also to improve their communication with the public and public adherence to instructions. The current review presents a conceptual framework for studying psychological aspects of crisis and risk communication using the social media through social computing. Advanced analytical tools can be integrated in the processes and objectives of crisis communication. The availability of the computational techniques can improve communication with the public by a process of Hyper-Targeted Crisis Communication. The review suggests that using advanced computational tools for target-audience profiling and linguistic matching in social media, can facilitate more sensitive and personalized emergency communication.

Personality traits are meaningful predictors of many significant life outcomes, including mortality. Several studies have investigated the relationship between specific personality traits and driving behaviours, e.g., aggression and speeding, in an attempt to identify traits associated with elevated crash risk. These studies, while valuable, are limited in that they examine only a narrow range of personality constructs and thus do not necessarily reveal which traits in constellation best predict aberrant driving behaviours. The primary aim of this study was to use a comprehensive measure of personality to investigate which personality traits are most predictive of four types of aberrant driving behaviour (Aggressive Violations, Ordinary Violations, Errors, Lapses) as indicated by the Manchester Driver Behaviour Questionnaire (DBQ). We recruited 285 young adults (67% female) from a university in the southeastern US. They completed self-report questionnaires including the DBQ and the Personality Inventory for DSM-5, which indexes 5 broad personality domains (Antagonism, Detachment, Disinhibition, Negative Affectivity, Psychoticism) and 25 specific trait facets. Confirmatory factor analysis showed adequate evidence for the DBQ internal structure. Structural regression analyses revealed that the personality domains of Antagonism and Negative Affectivity best predicted both Aggressive Violations and Ordinary Violations, whereas the best predictors of both Errors and Lapses were Negative Affectivity, Disinhibition and to a lesser extent Antagonism. A more nuanced analysis of trait facets revealed that Hostility was the best predictor of Aggressive Violations; Risk-taking and Hostility of Ordinary Violations; Irresponsibility, Separation Insecurity and Attention Seeking of Errors; and Perseveration and Irresponsibility of Lapses.

Fear of infectious disease often motivates people to protect themselves. But, it can also produce negative bio-social-psychological effects whose severity is on par with those of the disease. The WHO declaration of Zika as a world health crisis presented an opportunity to study factors that bring about fear. Beginning nine days after the WHO announcement, data were gathered from women aged 18-35 living in the southern United States (N = 719). Respondents reported experiencing fear of Zika at levels akin to those reported following other significant crises/disasters (e.g., the terrorist attacks of 9/11). Fear increased as a function of (1) personal, but not other-relevance, (2) frequency of media exposure, but not media content, and (3) frequency of interpersonal exposure and interpersonal content. It is argued that media and interpersonal message sources may be innately predisposed to amplify, rather than attenuate, risk. © 2018 Society for Risk Analysis.

Benford, Karis; Swami, Viren

2014-09-01

The present study examined associations between the Big Five personality domains and measures of men's body image. A total of 509 men from the community in London, UK, completed measures of drive for muscularity, body appreciation, the Big Five domains, and subjective social status, and provided their demographic details. The results of a hierarchical regression showed that, once the effects of participant body mass index (BMI) and subjective social status had been accounted for, men's drive for muscularity was significantly predicted by Neuroticism (β=.29). In addition, taking into account the effects of BMI and subjective social status, men's body appreciation was significantly predicted by Neuroticism (β=-.35) and Extraversion (β=.12). These findings highlight potential avenues for the development of intervention approaches based on the relationship between the Big Five personality traits and body image.

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

2017-08-05

Objective One of the biggest contributors to distracted driving among young people in the United States is technology. The objective of this study was to describe distracted driving behaviors among college students, with a specific focus on attitudes towards and use of social media. Methods With written permission, a survey was adapted from the Distracted Driving Public Opinion Poll distributed by the National Safety Council. The survey comprised 43 questions assessing attitudes and behaviors. A total of 411 students enrolled in a personal health course were invited to complete the survey. In total 324 surveys were completed, resulting in a response rate of 79%. Results Among students with a driver's license, 95.2% reported engaging in distracted driving behaviors. The use of social media while driving was common, with 30.7% reporting that they glance at, read, or post to social media while driving, most commonly on Snapchat or Instagram. It was common for students to make or answer phone calls (72.0%), review or send text messages (54.6%), or glance at or read automatic notifications (43.3%). Almost all students (91.5%) reported that they believed a hands-free solution is safer than holding the phone while driving, but only 67.9% reported that they usually used a hands-free device. Students in a health major and students who drive in urban areas were more likely to engage in distracted driving behaviors. Conclusions These findings suggest a need for interventions, particularly those which target adolescents in an attempt to deter these behaviors as they transition into adulthood.

Personality Traits, Motivations, and Emotional Consequences of Social Media Usage.

Lin, Jhih-Syuan; Lee, Yen-I; Jin, Yan; Gilbreath, Bob

2017-10-01

This study explores social media users' personality traits and motivations for the usage of two different social media platforms, Facebook and Pinterest, as well as how the varied uses impact users' negative emotional experiences. The findings suggest that the intensity of social media usage is positively related to negative emotions. For Facebook users, socialization, entertainment, and information seeking motivations significantly influence their platform use intensity and, subsequently, lead to negative emotions. Self-status seeking also has a direct effect on Facebook users' negative emotions. For Pinterest users, socialization is not a significant motivation for usage of that platform. However, entertainment, information seeking, and self-status seeking significantly predict their platform use intensity, which subsequently lead to negative emotions. Similarly, all four motivations for Facebook and Pinterest uses are influenced by users' personality traits: extraversion and openness. Yet, openness has a greater impact on using Pinterest than Facebook in terms of fulfilling socialization needs. Neuroticism has a positive impact on socialization and information seeking motives for use of both platforms, while conscientiousness and agreeableness have a negative influence on fulfilling self-status seeking needs. In addition, agreeable social networking site users are less likely to use Facebook than Pinterest for fulfilling self-status related gratifications, while they are likely to use Pinterest instead of Facebook for entertainment and information needs. Implications of the findings and suggestions for future research are discussed.

Traffic safety climate is defined as road users' attitudes and perceptions of traffic in a specific context at a given point in time. The current study aimed to validate the Chinese version of the Traffic Climate Scale (TCS) and to explore its relation to drivers' personality and dangerous driving behavior. A sample of 413 drivers completed the Big Five Inventory (BFI), the Chinese version of the TCS, the Dula Dangerous Driving Index (DDDI) and a demographic questionnaire. Exploratory factor analysis and confirmatory factor analysis were performed to confirm a three-factor (external affective demands, internal requirements and functionality) solution of the TCS. The reliability and validity of the Chinese version of TCS were verified. More importantly, the results showed that the effect of personality on dangerous driving behavior was mediated by traffic climate. Specifically, the functionality of the TCS mediated the effect of neuroticism on negative cognitive/emotional driving and drunk driving, while openness had an indirect impact on aggressive driving, risky driving and drunk driving based on the internal requirements of the TCS. Additionally, agreeableness had a negative direct impact on four factors of the DDDI, while neuroticism had a positive direct impact on negative cognitive/emotional driving, drunk driving and risky driving. In conclusion, the Chinese version of the TCS will be useful to evaluate drivers' attitudes towards and perceptions of the requirements of traffic environment in which they participate and will also be valuable for comparing traffic cultures and environments in different countries.

Driving behaviors play an important role in accident involvement. Concretely speaking, aberrant driving behaviors would cause more accidents, and oppositely positive driving behaviors would promote to build safety traffic environment. The main goals of this study were to explore the positive driving behavior and its relationship with personality in a Chinese sample. A total of 421 licensed drivers (286 male and 135 female) from Beijing, China completed the Positive Driver Behavior Scale (PDBS), the Driver Behavior Questionnaire (DBQ), the Dula Dangerous Driving Index (DDDI) and the Big Five Inventory (BFI) on a voluntary and anonymous basis. The results showed that the Chinese version of the PDBS has both reliability and validity and that the PDBS was significantly correlated with the BFI. Specifically, the PDBS was negatively correlated with neuroticism (r = -0.38) and positively correlated with extraversion, agreeableness, conscientiousness and openness to experience (the correlation coefficient ranged from 0.36 to 0.55). In contrast with previous research, age was negatively correlated with the PDBS (r = -0.38) in our sample, which may have resulted from less driving experience or a lack of available cognitive resources.

Appearance comparisons are an important sociocultural factor influencing women's body image. These comparisons can occur in different contexts (e.g., through magazines, social media, in person). However, little is known about the frequency and outcome of appearance comparisons made in different contexts in women's everyday lives. Using Ecological Momentary Assessment methods, female undergraduate students (n=146) completed a brief online survey at random times every day for 5 days. They reported the frequency, direction (upward, lateral, downward), and context of appearance comparisons, and also reported their appearance satisfaction, mood, and diet and exercise thoughts and behaviors. Upward appearance comparisons were the most common across all contexts. Upward comparisons through social media were associated with more negative outcomes on all measures (except diet and exercise behavior) than comparisons made in person, and with more negative mood than comparisons in any other context. These findings highlight the importance of the appearance comparison context. Copyright © 2016 Elsevier Ltd. All rights reserved.

The present study examined the impact of thin-ideal media exposure on Chinese women's drive for thinness, attitudes towards body shape, and eating attitude. Women were assigned to one of two video conditions, which portrayed the thin-ideal (experimental) or was neutral (control group), in terms of content. A total of 83 young women from Hong Kong (N = 38) and Shanghai (N = 45), aged between 18 and 25 years (M age  = 22.7) participated in the study. A significant interaction was observed between the experimental video condition and location. Hong Kong women in the experimental group experienced greater levels of body dissatisfaction than Shanghai women exposed to the same condition. Exposure to thin-ideal media produced an increase in drive for thinness, body dissatisfaction and problematic eating attitudes regardless of location, with a greater immediate impact shown in Hong Kong women.

Positive face-to-face human interactions are known to benefit well-being. Drawing upon previous work regarding the interference of media (via technological devices or print) in social interaction, the aim of this study was to identify whether using media during face-to-face interaction could potentially limit the positive effect of interaction on well-being. Participants were 437 university students who completed an online survey which assessed media multitasking behaviors, well-being (trait depression, trait anxiety, social anxiety, empathy, and psychological well-being), and personality traits (Big-5 and narcissism). Face-to-face interaction was positively associated with well-being. However, when media use during face-to-face interaction was considered, there was a negative relationship with well-being (more depression, more anxiety, and less psychological well-being). Those who used certain media types, such as phone or video chatting, listening to music, and gaming, while interacting with others, also had lower scores on measures of empathy. Regression analyses showed significant contributions by these media types to empathy levels, even after controlling for age, gender, and personality traits. Face-to-face media multitasking was related to higher levels of narcissism and neuroticism, and lower levels of agreeableness, conscientiousness, and openness. This study provides insight into the possible role of media multitasking during face-to-face interaction on psychosocial outcomes.

Drivers' behaviors such as violations and errors have been demonstrated to predict crash involvement among young Omani drivers. However, there is a dearth of studies linking risky driving behaviors to the personality of young drivers. The aim of the present study was to assess such traits within a sample of young Omani drivers (as measured through the behavioral inhibition system [BIS] and the behavioral activation system [BAS]) and determine links with aberrant driving behaviors and self-reported crash involvement. A cross-sectional study was conducted at the Sultan Qaboos University that targeted all licensed Omani's undergraduate students. A total of 529 randomly selected students completed the self-reported questionnaire that included an assessment of driving behaviors (e.g., Driver Behaviour Questionnaire, DBQ) as well as the BIS/BAS measures. A total of 237 participants (44.8%) reported involvement in at least one crash since being licensed. Young drivers with lower BIS-Anxiety scores and higher BAS-Fun Seeking tendencies as well as male drivers were more likely to report driving violations. Statistically significant gender differences were observed on all BIS and BAS subscales (except for BAS-Fun) and the DBQ subscales, because males reported higher trait scores. Though personality traits were related to aberrant driving behaviors at the bivariate level, the constructs were not predictive of engaging in violations or errors. Furthermore, consistent with previous research, a supplementary multivariate logistic regression analysis revealed that only driving experience was predictive of crash involvement. The findings highlight that though personality traits influence self-reported driving styles (and differ between the genders), the relationship with crash involvement is not as clear. This article further outlines the key findings of the study in regards to understanding core psychological constructs that increase crash risk.

The drive for muscularity and associated behaviors (e.g., exercising and dieting) are of growing importance for men in Western societies. In its extreme form, it can lead to body image concerns and harmful behaviors like over-exercising and the misuse of performance-enhancing substances. Therefore, investigating factors associated with the drive for muscularity, especially in vulnerable populations like bodybuilders and weight trainers can help identify potential risk and protective factors for body image problems. Using a biopsychosocial framework, the aim of the current study was to explore different factors associated with drive for muscularity in weight-training men. To this purpose, German-speaking male weight trainers (N = 248) completed an online survey to determine the extent to which biological, psychological, and sociocultural factors contribute to drive for muscularity and its related attitudes and behaviors. Using multiple regression models, findings showed that media ideal body internalization was the strongest positive predictor for drive for muscularity, while age (M = 25.9, SD = 7.4) held the strongest negative association with drive for muscularity. Dissatisfaction with muscularity, but not with body fat, was related to drive for muscularity. The fat-free mass index, a quantification of the actual degree of muscularity of a person, significantly predicted drive for muscularity-related behavior but not attitudes. Body-related aspects of self-esteem, but not global self-esteem, were significant negative predictors of drive for muscularity. Since internalization of media body ideals presented the highest predictive value for drive for muscularity, these findings suggest that media body ideal internalizations may be a risk factor for body image concerns in men, leading, in its most extreme form to disordered eating or muscle dysmorphia. Future research should investigate the relations between drive for muscularity, age, body composition

In some studies, the involvement of dangerous psychological and behavioral factors in etiology and physiotherapy of vascular disturbances have been shown. In other studies, the relationship between the personality type and increase in cardiovascular disease has been demonstrated. The type D personality is defined as having two characteristics of negative affect and social inhibition. It is thought that individuals with type D personality are at increased risk of carotid artery intima-media thickening which predisposes them to vascular disease that is one of the most important factors for the stroke. In this study, we try to determine whether type D personality is a contributing factor to an increase in the intima-media of the carotid artery. This study was done in 2012 in the teaching hospital of Alzahra in Isfahan Iran. This is a case/control study which is done at Alzahra hospital in Isfahan in 2011-12. The statistical population in this study is composed of individuals who do not have any risk factors for stroke and are randomly selected among the hospital staff or the patient's family members who accompanied the patient at the hospital. They filled out a questioner that would assist in detecting type D personality. A carotid Doppler ultrasound that measures the intima-media thickness in the selected individuals was performed. The information obtained from the study was evaluated by Statistical Product and Service Solutions (SPSS) software and the intima-media thicknesses were compared in two groups of patients. The average thickness of intima media in two groups, consist of placebo and patients, was 0.739 ± 0.12 and 0.759 ± 0.14 millimeter, respectively. There was no meaningful difference between the two groups based on t-test values (P = 0.19). It is important to note that based on the results, 22.9% of placebos and 48.6% of individuals with type D personality presented with abnormal thickness. The difference between the two groups were meaningful based on

The purpose of this research was to assess the impact of nonstereotypical, positive media portrayals of obese persons on biased attitudes, as well as propose a change in media practices that could reduce public weight bias and consequent negative health outcomes for those who experience weight stigma. Two online experiments were conducted in which participants viewed either a stigmatizing or a positive photograph of an obese model. In Experiment 1 (N = 146), participants viewed a photograph of either a Caucasian or African American obese woman; in Experiment 2 (N = 145), participants viewed either a Caucasian male or female obese model. Multiple linear regression models were used to analyze outcomes for social distance attitudes toward the obese models depicted in the images, in addition to other negative attitudes and image preferences. Participants who viewed the stigmatizing images endorsed stronger social distance attitudes and more negative attitudes toward obese persons than participants who viewed the positive images, and there was a stronger preference for the positive images than the stigmatizing images. These results were consistent regardless of the race or gender of the obese model pictured. The findings indicate that more positive media portrayals of obese individuals may help reduce weight stigma and its associated negative health outcomes.

Social media has enabled information, communication and reach for health professionals. There are clear benefits to patients and consumers when health information is broadcast. But there are unanswered questions on professionalism, education, and the complex mentoring relationship between doctor and student. This personal perspective raises a number of questions: What is online medical professionalism? Can online medical professionalism be taught? Can online medical professionalism be enforced? Is an online presence necessary to achieve the highest level of clinical excellence? Is there evidence that social media is superior to traditional methods of teaching in medical education? Does social media encourage multitasking and impairment of the learning process? Are there downsides to the perfunctory laconic nature of social media? Does social media waste time that is better spent attaining clinical skills?

Underage female DUI offenders: personality characteristics, psychosocial stressors, alcohol and other drug use, and driving-risk.

Moore, R H

1994-04-01

164 underage female DUI offenders were evaluated on measures of personality, driving-risk, psychosocial stressors, alcohol and other drug use, alcohol abuse, and symptoms of depression. Empirical classification of 10 groups represented five distinct types. 31 youth who were classified as Antisocial exhibited highest rates of alcohol misuse, other drug use, deviant driving behavior, traffic offenses and accidents, and psychosocial stressors. About 56% or 92 appeared to experience impaired functioning serious enough to warrant interventions more intense than educational classes. A measure of driving-risk developed and used in studies of male adults, the Donovan Research Questionnaire, did not appear to differentiate driving-risk among the young women. In contrast to male drivers, who often expressed anger or aggression through driving, most subjects appeared to react to emotion-eliciting stimuli with feelings of low self-worth or dysphoric affect rather than anger. Specialized screening suitable for young female DUI offenders should be considered.

Mass media campaigns have long been used as a tool for promoting public health. In the past decade, the growth of social media has allowed more diverse options for mass media campaigns. This systematic review was conducted to assess newer evidence from quantitative studies on the effectiveness of mass media campaigns for reducing alcohol-impaired driving (AID) and alcohol-related crashes, particularly after the paper that Elder et al. published in 2004. This review focused on English language studies that evaluated the effect of mass media campaigns for reducing AID and alcohol-related crashes, with or without enforcement efforts. A systematic search was conducted for studies published between January 1, 2002 and December 31, 2013. Studies from the review by Elder et al. were added as well. A total of 19 studies met the inclusion criteria for the systematic review, including three studies from the review by Elder et al. Nine of them had concomitant enforcement measures and did not evaluate the impact of media campaigns independently. Studies that evaluated the impact of mass media independently showed reduction more consistently (median -15.1%, range -28.8 to 0%), whereas results of studies that had concomitant enforcement activities were more variable (median -8.6%, range -36.4 to +14.6%). Summary effects calculated from seven studies showed no evidence of media campaigns reducing the risk of alcohol-related injuries or fatalities (RR 1.00, 95% CI = 0.94 to 1.06). Despite additional decade of evidence, reviewed studies were heterogeneous in their approaches; therefore, we could not conclude that media campaigns reduced the risk of alcohol-related injuries or crashes. More studies are needed, including studies evaluating newly emerging media and cost-effectiveness of media campaigns.

Driving is the primary means of personal travel in many countries and is relies heavily on vision for its successful execution. Research over the past few decades has addressed the role of vision in driver safety (motor vehicle collision involvement) and in driver performance (both on-road and using interactive simulators in the laboratory). Here we critically review what is currently known about the role of various aspects of visual function in driving. We also discuss translational research issues on vision screening for licensure and re-licensure and rehabilitation of visually impaired persons who want to drive. PMID:20580907

The aim of this study was to evaluate the effect of variables such as personality traits, driving behavior and mental illness on road traffic accidents among the drivers with accidents and those without road crash. In this cohort study, 800 bus and truck drivers were recruited. Participants were selected among drivers who referred to Imam Sajjad Hospital (Tehran, Iran) during 2013-2015. The Manchester driving behavior questionnaire (MDBQ), big five personality test (NEO personality inventory) and semi-structured interview (schizophrenia and affective disorders scale) were used. After two years, we surveyed all accidents due to human factors that involved the recruited drivers. The data were analyzed using the SPSS software by performing the descriptive statistics, t-test, and multiple logistic regression analysis methods. P values less than 0.05 were considered statistically significant. In terms of controlling the effective and demographic variables, the findings revealed significant differences between the two groups of drivers that were and were not involved in road accidents. In addition, it was found that depression and anxiety could increase the odds ratio (OR) of road accidents by 2.4- and 2.7-folds, respectively (P=0.04, P=0.004). It is noteworthy to mention that neuroticism alone can increase the odds of road accidents by 1.1-fold (P=0.009), but other personality factors did not have a significant effect on the equation. The results revealed that some mental disorders affect the incidence of road collisions. Considering the importance and sensitivity of driving behavior, it is necessary to evaluate multiple psychological factors influencing drivers before and after receiving or renewing their driver's license.

The stigmatizing effect of visual media portrayals of obese persons on public attitudes: does race or gender matter?

PubMed

Puhl, Rebecca M; Luedicke, Joerg; Heuer, Chelsea A

2013-01-01

Overweight and obese persons are frequently stigmatized in news media. The present study is the first to systematically compare public reactions to positive and negative images of obese persons accompanying news reports on obesity (while manipulating gender and race of the target)and their effects on generalized attitudes and social distance toward obese persons. The authors conducted 3 randomized experimental studies using online surveys to assess public perceptions of positive versus stereotypical images of obese adults (who varied by gender and race) accompanying a neutral news report about obesity. The sample included 1,251 adults, who were recruited through a national survey panel during May of 2010. Participants who viewed negative, stereotypical images of obese targets increased social distance, antifat attitudes, and ratings of laziness and dislike toward obese persons, whereas positive, nonstereotypical images induced more positive attitudes. These findings remained consistent when accounting for sociodemographic variables. African American female obese targets portrayed in images evoked higher ratings of dislike and social distance compared with Caucasian targets, but ratings were similar for male and female targets. This study provides evidence that images of obese person accompanying written media influence public attitudes toward obese people, and may reinforce weight stigmatization if images contain stereotypical portrayals of obese persons. Implications for efforts to report about obesity in the news media are discussed.

Media data has been the subject of large scale analysis with applications of text mining being used to provide overviews of media themes and information flows. Such information extracted from media articles has also shown its contextual value of being integrated with other data, such as criminal records and stock market pricing. In this work, we explore linking textual media data with curated secondary textual data sources through user-guided semantic lexical matching for identifying relationships and data links. In this manner, critical information can be identified and used to annotate media timelines in order to provide a more detailed overview of events that may be driving media topics and frames. These linked events are further analyzed through an application of causality modeling to model temporal drivers between the data series. Such causal links are then annotated through automatic entity extraction which enables the analyst to explore persons, locations, and organizations that may be pertinent to the media topic of interest. To demonstrate the proposed framework, two media datasets and an armed conflict event dataset are explored.

Healthcare managers in negative media focus: a qualitative study of personification processes and their personal consequences

PubMed Central

2014-01-01

Background Over the last decade healthcare management and managers have increasingly been in focus in public debate. The purpose of the present study was to gain a deeper understanding of how prolonged, unfavorable media focus can influence both the individual as a person and his or her managerial practice in the healthcare organization. Methods In-depth interviews (n = 49) with 24 managers and their superiors, or subordinate human resources/information professionals, and partners were analyzed using a grounded theory approach. Results The conceptual model explains how perceived uncertainties related to the managerial role influence personification and its negative consequences. The role ambiguities comprised challenges regarding the separation of individual identity from the professional function, the interaction with intra-organizational support and political play, and the understanding and acceptance of roles in society. A higher degree of uncertainty in role ambiguity increased both personification and the personal reaction to intense media pressure. Three types of reactions were related to the feeling of being infringed: avoidance and narrow-mindedness; being hard on self, on subordinates, and/or family members; and resignation and dejection. The results are discussed so as to elucidate the importance of support from others within the organization when under media scrutiny. Conclusions The degree of personification seems to determine the personal consequences as well as the consequences for their managerial practice. Organizational support for managers appearing in the media would probably be beneficial for both the manager and the organization. PMID:24397306

Abstract Objective To provide primary care physicians with an approach to driving safety concerns when older persons present with memory difficulties. Sources of information The approach is based on an accredited memory clinic training program developed by the Centre for Family Medicine Primary Care Collaborative Memory Clinic. Main message One of the most challenging aspects of dementia care is the assessment of driving safety. Drivers with dementia are at higher risk of motor vehicle collisions, yet many drivers with mild dementia might be safely able to continue driving for several years. Because safe driving is dependent on multiple cognitive and functional skills, clinicians should carefully consider many factors when determining if cognitive concerns affect driving safety. Specific findings on corroborated history and office-based cognitive testing might aid in the physician’s decisions to refer for comprehensive on-road driving evaluation and whether to notify transportation authorities in accordance with provincial reporting requirements. Sensitive communication and a person-centred approach are essential. Conclusion Primary care physicians must consider many factors when determining if cognitive concerns might affect driving safety in older drivers. PMID:28115437

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.

Trends in media use.

Roberts, Donald F; Foehr, Ulla G

2008-01-01

American youth are awash in media. They have television sets in their bedrooms, personal computers in their family rooms, and digital music players and cell phones in their backpacks. They spend more time with media than any single activity other than sleeping, with the average American eight- to eighteen-year-old reporting more than six hours of daily media use. The growing phenomenon of "media multitasking"--using several media concurrently--multiplies that figure to eight and a half hours of media exposure daily. Donald Roberts and Ulla Foehr examine how both media use and media exposure vary with demographic factors such as age, race and ethnicity, and household socioeconomic status, and with psychosocial variables such as academic performance and personal adjustment. They note that media exposure begins early, increases until children begin school, drops off briefly, then climbs again to peak at almost eight hours daily among eleven- and twelve-year-olds. Television and video exposure is particularly high among African American youth. Media exposure is negatively related to indicators of socioeconomic status, but that relationship may be diminishing. Media exposure is positively related to risk-taking behaviors and is negatively related to personal adjustment and school performance. Roberts and Foehr also review evidence pointing to the existence of a digital divide--variations in access to personal computers and allied technologies by socioeconomic status and by race and ethnicity. The authors also examine how the recent emergence of digital media such as personal computers, video game consoles, and portable music players, as well as the media multitasking phenomenon they facilitate, has increased young people's exposure to media messages while leaving media use time largely unchanged. Newer media, they point out, are not displacing older media but are being used in concert with them. The authors note which young people are more or less likely to use several

Individual differences in in-person and social media television coviewing: the role of emotional contagion, need to belong, and coviewing orientation.

2014-08-01

The popularity of social media television coviewing is growing, but little is known about why people engage in these connected viewing experiences or how they differ from in-person coviewing. This study investigated how engaging in in-person and social media coviewing is predicted by individual differences: emotional contagion, need to belong, and three dimensions of a coviewing orientation scale created for this research (need for company, need for solitude, and audience monitoring). On Amazon Mechanical Turk, 451 people were recruited for an online survey. The mean age was 34.64 years (SD=13.16 years), and 52% of the sample was female. Emotional contagion predicted in-person coviewing only. Need to belong predicted several mediated co-viewing activities. Need for solitude negatively predicted in-person coviewing, but need for company positively predicted in-person coviewing. Results indicate that viewers have different motivations for engaging in various coviewing activities. Findings also suggest that social media coviewing can provide valuable opportunities for social connection among viewers who watch television in physical solitude.

Besides, demographic variables (sex and age) and the big five personality traits were examined as potential impact factors of aggressive driving. A total of 422 participants completed the DAIS, Big Five Personality Inventory (BFPI), and the socio-demographic scale. First, psychometric results confirmed that the DAIS had a stable two-factor structure and acceptable internal consistency. Then, agreeableness and conscientiousness were negatively correlated with hostile aggression and revenge committed by the drivers themselves, while neuroticism was positively correlated with aggressive driving committed by the drivers themselves. Meanwhile, more agreeable drivers may perceive less hostile aggression and revenge. More neurotic drivers may perceive more aggressive warning. Finally, the effects of age and sex on aggressive driving were not same as most studies. We found that older age group perceived and committed more hostile acts of aggression and revenge than younger age groups. Female drivers of 49-60 years perceived more aggressive warnings committed by other drivers. Copyright © 2017 Elsevier Ltd. All rights reserved.

Predictors of Cell Phone Use in Distracted Driving: Extending the Theory of Planned Behavior.

PubMed

Tian, Yan; Robinson, James D

2017-09-01

This study examines the predictors of six distracted driving behaviors, and the survey data partially support Ajzen's (1991) Theory of Planned Behavior (TPB). The data suggest that the attitude variable predicted intention to engage in all six distracted driving behaviors (reading and sending text messages, making and answering cell phone calls, reading/viewing social media, and posting on social media while driving). Extending the model to include past experience and the variable perceived safety of technology yielded an improvement in the prediction of the distraction variables. Specifically, past experience predicted all six distracted driving behaviors, and the variable perceived safety of technology predicted intentions to read/view social media and intention to post on social media while driving. The study provides evidence for the importance of incorporating expanded variables into the original TPB model to predict cell phone use behaviors while driving, and it suggests that it is essential to tailor campaign materials for each specific cell phone use behavior to reduce distracted driving.

Drive for muscularity and drive for thinness: the impact of pro-anorexia websites.

PubMed

Juarez, Lilia; Soto, Ernesto; Pritchard, Mary E

2012-01-01

In recent years, websites that stress the message of thinness as the ideal and only choice have surfaced on the internet. The possibility that pro-anorexia websites may reinforce restrictive eating and exercise behaviors is an area of concern. In addition, friends may be influencing one another to view these websites, further contributing to drive for thinness in women and drive for muscularity in men. Three hundred male and female undergraduate psychology students responded to questionnaires assessing: internalization of pro-anorexia website content, internalization of general media content, influence of friends to view pro-anorexia websites, peer influence, drive for muscularity, and drive for thinness. Results showed internalization of pro-anorexia website content was positively correlated with drive for thinness in women, and negatively correlated with drive for muscularity in men. Internalization of pro-anorexia website content was found to be related to both drive for thinness in women and drive for muscularity in men.

Age and inconsistency in driving performance.

Research in cognitive neuropsychology suggests that investigation of the within-person variability, or inconsistency, of cognitive performance may provide valuable insights into ageing mental processes. It is rare though, for this interest in intraindividual variability to extend to everyday activities. As this may provide important information about driving behaviour, we therefore assessed age differences in driving inconsistency in younger (n=24, M age=21.29 years) and older (n=21, M age=71.24 years) persons who drove in residential, urban and motorway conditions in a fully immersive driving simulator. In measures of headway (maintaining a safe distance to a preceding vehicle) and lateral lane position, older drivers exhibited significantly greater performance inconsistency, and this was particularly marked in the faster motorway condition. Older drivers also recorded greater perceived mental demands associated with driving, and greater within-person variability across a range of cognitive measures. The findings suggest that age-related deficits in attentional and executive control may affect the consistency of driving performance in older persons. Discussion considers interventions to introduce in-vehicle systems to help maintain attention in older drivers, and to intervene when safety-critical boundaries are exceeded.

This study examined the mass media and personal characteristics leading to health communication inequality as well as the role of certain factors in health communication's mass media process. Using both sociodemographic variables and Maletzke's model as a basis, we investigated the relationship between selected components of the mass communication process, the receiving of reliable health information as a result of health communication, and the condition of its use. The study involved 1853 people in Turkey and was structured in two parts. The first part dealt with questions regarding sociodemographic characteristics, the use of the mass media and the public's ability to obtain health information from it, the public's perception of the trustworthiness of health information, and the state of translating this information into health-promoting behaviours. In the second part, questions related to the mass communication process were posed using a five-point Likert scale. This section tried to establish structural equation modelling using the judgements prepared on the basis of the mass media model. Through this study, it has been observed that sociodemographic factors such as education and age affect individuals' use of and access to communication channels; individuals' trust in and selection of health information from the programme content and their changing health behaviours (as a result of the health information) are related to both their perception of the mass communication process and to sociodemographic factors, but are more strongly related to the former. © The Author(s) 2014.

Optotech 5984 Drive Overview

NASA Astrophysics Data System (ADS)

Lee, Tzuo-Chang; Chen, Di

We present in this paper an overview of Optotech's 5984 Optical Disk Drive. Key features such as the modulation code, the disk format, defect mapping scheme and the optical head and servo subsystem will be singled out for discussion. Description of Optotech's 5984 disk drive The Optotech 5984 optical disk drive is a write-once-read-mostly (WORM) rotating optical memory with 200 Megabyte capacity on each side of the disk. It has a 5 1/4 inch form factor that will fit into any personal computer full-height slot. The drive specification highlights are given in Table 1. A perspective view of the drive mechanical assembly is shown in Figure 1. The spindle that rotates the disk has a runout of less than 10 um. The rotational speed at 1200 revolutions per minute (rpm) is held to an accuracy of 10-3. The total angular tolerance from perfect perpendicular alignment between the rotating disk and the incident optical beam axis is held to less than 17 milliradians. The coarse seek is accomplished through a stepping motor driving the optical head with 1.3 milliseconds per step or 32 tracks per step. The analog channels including read/write, the phase lock loop and the servo loops for focus and track control are contained on one surface mount pc board while the digital circuitry that interfaces with the drive and the controller is on a separate pc board. A microprocessor 8039 is used to control the handshake and the sequence of R/W commands. A separate power board is used to provide power to the spindle and the stepping motors. In the following we will discuss some of the salient features in the drive and leave the details to three accompanying Optotech papers. These salient features are derived from a design that is driven by three major considerations. One is precise control of the one micron diameter laser spot to any desired location on the disk. The second consideration is effective management of media defects. Given the state of the art of the Te-based disk technology with

Introducing a multivariate model for predicting driving performance: the role of driving anger and personal characteristics.

Maladaptive driving is an important source of self-inflicted accidents and this driving style could include high speeds, speeding violations, and poor lateral control of the vehicle. The literature suggests that certain groups of drivers, such as novice drivers, males, highly motivated drivers, and those who frequently experience anger in traffic, tend to exhibit more maladaptive driving patterns compared to other drivers. Remarkably, no coherent framework is currently available to describe the relationships and distinct influences of these factors. We conducted two studies with the aim of creating a multivariate model that combines the aforementioned factors, describes their relationships, and predicts driving performance more precisely. The studies employed different techniques to elicit emotion and different tracks designed to explore the driving behaviors of participants in potentially anger-provoking situations. Study 1 induced emotions with short film clips. Study 2 confronted the participants with potentially anger-inducing traffic situations during the simulated drive. In both studies, participants who experienced high levels of anger drove faster and exhibited greater longitudinal and lateral acceleration. Furthermore, multiple linear regressions and path-models revealed that highly motivated male drivers displayed the same behavior independent of their emotional state. The results indicate that anger and specific risk characteristics lead to maladaptive changes in important driving parameters and that drivers with these specific risk factors are prone to experience more anger while driving, which further worsens their driving performance. Driver trainings and anger management courses will profit from these findings because they help to improve the validity of assessments of anger related driving behavior. © 2013.

Stepping in to the social media world: reflections from both personal and institutional points of view (Invited)

2013-12-01

Like it or not, the world is increasingly run by social media. It has completely transformed the delivery of and access to news, and data show that half or more U.S. citizens now get their news from some form of social media. Interactive web tools determine political campaigns and help catalyze country-scale revolutions. They allow very personal access in ways both good and bad, as well as the rapid dissemination of both high quality information and complete falsehoods. But though they have plenty of downsides, their central and still-rising presence in society means that scientists who study any aspect of global environmental change (as well as those in most other areas of science) cannot afford to be social media luddites. In this panel, I will talk about my recent experiences in diving into this world, from both personal and institutional perspectives. For the former, I'll discuss some lessons learned in adding twitter and a blog to my professional life, and why I ultimately chose to have the blog reveal substantial information about me, not just the science I pursue. For the latter, I'll discuss launching the first blog in the history of the National Science Foundation and what that experience revealed about pushing social media advances on an institutional scale.

Digital watermarking opportunities enabled by mobile media proliferation

NASA Astrophysics Data System (ADS)

Modro, Sierra; Sharma, Ravi K.

2009-02-01

Consumer usages of mobile devices and electronic media are changing. Mobile devices now include increased computational capabilities, mobile broadband access, better integrated sensors, and higher resolution screens. These enhanced features are driving increased consumption of media such as images, maps, e-books, audio, video, and games. As users become more accustomed to using mobile devices for media, opportunities arise for new digital watermarking usage models. For example, transient media, like images being displayed on screens, could be watermarked to provide a link between mobile devices. Applications based on these emerging usage models utilizing watermarking can provide richer user experiences and drive increased media consumption. We describe the enabling factors and highlight a few of the usage models and new opportunities. We also outline how the new opportunities are driving further innovation in watermarking technologies. We discuss challenges in market adoption of applications based on these usage models.

Introduction Personality characteristics are associated with many risk behaviors. However, the relationship between personality traits, risky driving behavior, and crash risk is poorly understood. The purpose of this study was to examine the association between personality, risky driving behavior and crashes and near-crashes, using naturalistic driving research methods. Method Participants’ driving exposure, kinematic risky driving (KRD), high-risk secondary task engagement, and the frequency of crashes and near-crashes (CNC) were assessed over the first 18 months of licensure using naturalistic driving methods. A personality survey (NEO-Five Factor Inventory) was administered at baseline. The association between personality characteristics, KRD rate, secondary task engagement rate and CNC rate was estimated using a linear regression model. Mediation analysis was conducted to examine if participants’ KRD rate or secondary task engagement rate mediated the relationship between personality and CNC. Data were collected as part of the Naturalistic Teen Driving Study. Results Conscientiousness was marginally negatively associated with CNC (path c = −0.034, p = .09) and both potential mediators KRD (path a = −0.040, p = .09) and secondary task engagement while driving (path a = −0.053, p = .03). KRD, but not secondary task engagement, was found to mediate (path b = 0.376, p = .02) the relationship between conscientiousness and CNC (path c’ = −0.025, p = .20). Conclusions Using objective measures of driving behavior and a widely used personality construct, these findings present a causal pathway through which personality and risky driving are associated with CNC. Specifically, more conscientious teenage drivers engaged in fewer risky driving maneuvers, suffered fewer CNC. Practical Applications Part of the variability in crash-risk observed among newly licensed teenage drivers can be explained by personality. Parents and driving instructors may take teenage

Racing games have emerged as top-selling products in the video and computer game industry. The effect of playing racing games on the inclination of gamers to take risks has been investigated. Two experiments were conducted. In experiment 1, the impact of personality traits on the effects of playing racing games on risk-taking inclination was examined. The Vienna Test System, which includes the Eysenck Personality Profile Test and the Vienna Risk-Taking Test, was used to measure risk-taking inclination and risk-taking while driving. Experiment 2 was designed and conducted to analyse the effects of different intensity levels of car racing games on risk-taking inclination, and to study the relationship between physiological data and risk-taking inclination. Physiological data on skin conductance, heart rate and blood pressure were measured with the NeuroDyne System. Participants playing a racing game were more inclined to take risks in critical road traffic situations than those playing a neutral game. The adventurousness dimension of the Eysenck Personality Profile Test correlated significantly positively with risk-taking inclination. More importantly, the effect of the intensity level of a racing game on risk-taking inclination was significant. The higher the intensity level of the racing game, the higher the risk-taking inclination while driving. The effect of intensity level of the racing game on skin conductance was significantly positive. Skin conductance correlated significantly positively with risk-taking inclination. The effect of playing racing games on risk-taking inclination is linked to personality and physiological data. Some recommendations are proposed as a result of this study for racing game management.

2013-11-01

The main goal of this study was to assess how the millennial generation perceives companies that have different social media policies and how such perception influences key variables for job-seeking behaviors, including perceived person-organization fit (POF), organizational attraction, and job pursuit intention. Results from a univariate general linear model and path analysis supported all of the established hypotheses. In particular, the results revealed that millennials perceived higher POF for a company with organizational policies supporting employees' social media use. Further, organizational attractiveness significantly mediated the relationship between communication-oriented POF and job pursuit intention.

Safety concerns together with aging of the driving population has prompted research into clinic-based driving assessments. This study investigates the relationship between the DriveSafe and DriveAware assessments and restriction of driving. Community-dwelling adults aged more than 75 (n = 380) were recruited in New South Wales, Australia. Questionnaires were administered to assess driving habits and functional assessments to assess driving-related function. Self-reported restriction was prevalent in this cross-sectional sample (62%) and was related to DriveSafe scores and personal circumstances but not DriveAware scores. DriveSafe scores were correlated with better performance on the Trail-Making Test (TMT; β = -2.94, p < .0001) and better contrast sensitivity (β = 48.70, p < .0001). Awareness was associated with better performance on the TMT (β = 0.08, p < .0001). Our data suggest that DriveSafe and DriveAware are sensitive to deficits in vision and cognition, and drivers with worse DriveSafe scores self-report restricting their driving. © The Author(s) 2015.

Method And Apparatus For Arbitrarily Large Capacity Removable Media

A method and apparatus to handle multiple sets of removable media within a storage system. A first set of removable media are mounted on a set of drives. Data is accepted until the first set of removable media is filled. A second set of removable media is mounted on the drives, while the first set of removable media is removed. When the change in removable media is complete, writing of data proceeds on the second set of removable media. Data may be buffered while the change in removable media occurs. Alternatively, two sets of removable media may be mounted at the same time. When the first set of removable media is filled to a selected amount, the second set of removable media may then be used to write the data. A third set of removable media is set up or mounted for use, while the first set of removable media is removed.

Toward a deeper characterization of the social phenotype of Williams syndrome: the association between personality and social drive

2014-01-01

Previous research has robustly established a Williams syndrome (WS) specific personality profile, predominantly characterized a gregarious, people-oriented, and tense predisposition. Extending this work, the aims of the current, cross-sectional study were two-fold: (1) to elucidate the stability of personality characteristics in individuals with WS and typically developing (TD) comparisons across development, and (2) to explore the personality attributes that may be related to the respective profiles of social functioning characterizing the two groups, which is currently poorly understood. The sample comprised of participants with WS and TD matched on chronological age. The test battery included the Multidimensional Personality Questionnaire (MPQ) and the Salk Institute Sociability Questionnaire (SISQ), an index of real-life social behavior. The main results showed that compared to the TD individuals, the WS group were consistently rated higher in Social Closeness, and this trait remained stable across development. Interpersonal behaviors were best predicted by Social Closeness in WS and by Social Potency in TD. Regression analysis highlighted that while a central motive underlying the increased drive toward social interaction in individuals with WS pertains to a desire to form affectionate relationships, TD individuals by contrast are motivated by a desire to exert social influence over others (leadership, social-dominance) and Well-Being (positive emotional disposition). In conclusion, these findings provide novel insight into social motivational factors underpinning the WS social behavior in real life, and contribute toward a deeper characterization of the WS affiliative drive. We suggest potential areas for behavioral intervention targeting improved social adjustment in individuals with WS. PMID:24794322

Lubricant distribution and its effect on slider air bearing performance over bit patterned media disk of disk drives

NASA Astrophysics Data System (ADS)

Wu, Lin

2011-04-01

The distribution dynamics of a thin lubricant film on a bit-patterned media disk and its effect on the performance of the ultralow flying air bearing slider of disk drives are studied by direct numerical simulations. Our analysis shows that the physics governing lubricant distribution dynamics changes when deep enough sub-100-nm nanostructures are patterned on the disk surface. Air shearing under the slider that dominates lubricant flow on a flat disk may become negligible on a bit-patterned media disk. Surface tension and disjoining pressure become dominant factors instead. Our results show that disks with nanoscale patterns/roughness may no longer be treated as flat, and the air bearing load may strongly depend not only on the geometric detail of disk patterns but also on how lubricants are distributed on the patterns when slider-disk clearance is reduced to sub-10-nm. Air bearing load and consequently the slider's flying attitude are affected by disk pattern geometry, average lubricant thickness, and material properties of lubricant such as the surface tension coefficient and Hamaker constant. The significantly expanded parameter space, upon which ultralow flying slider's dynamics depends, has to be seriously considered in evaluating the head/disk interface tribology performance of next generation patterned media magnetic recording systems.

Effects of license revocation on drunk-driving offenders.

PubMed

1988-10-01

Revoking or suspending the licenses of persons convicted of driving while intoxicated has often been claimed to be uniquely effective in reducing subsequent dangerous driving, as indexed by crashes and violations. This finding holds despite the impression that many suspended and revoked drivers continue to drive illegally. The research described here inquires into the operation of license actions. It uses intensive personal interviews with offenders to obtain information concerning the nature and amount of illegal driving and the effects of license deprivation on employment and other aspects of the offenders' lives.

All states in the U.S. prohibit alcohol-impaired driving but active law enforcement is necessary for effectively reducing this behavior. Sobriety checkpoints, saturation patrols, open container laws, and media campaigns related to enforcement efforts are all enforcement-related strategies for reducing alcohol-impaired driving. We conducted surveys of all state patrol agencies and a representative sample of local law enforcement agencies to assess their use of alcohol-impaired driving enforcement-related strategies and to determine the relationship between these enforcement-related strategies and self-reported alcohol-impaired driving behavior obtained from the Behavioral Risk Factor Surveillance System. We found that sobriety checkpoints, saturation patrols, and enforcement of open container laws were associated with a lower prevalence of alcohol-impaired driving but, more importantly, a combination of enforcement-related strategies was associated with a greater decrease in alcohol-impaired driving than any individual enforcement-related activity. In addition, alcohol-impaired driving enforcement-related strategies were associated with decreased alcohol-impaired driving above and beyond their association with decreased binge drinking. Results suggest law enforcement agencies should give greater priority to using a combination of strategies rather than relying on any one individual enforcement activity.

2017-09-01

To relate personality characteristics at the age of 12 to socioeconomic differences in health care use in young adulthood. And thereby examining the extent to which socioeconomic differences in the use of health care in young adulthood are based on differences in personality characteristics, independent of the (parental) socioeconomic background. Personality of more than 13,000 Dutch 12-year old participants was related to their health and socioeconomic position after a follow-up of 13 years (when the participants had become young adults). In young adulthood, low socioeconomic status was related to high health care use (e.g. low education -hospital admission: OR = 2.21; low income -GP costs: OR = 1.25). Odds ratios (for the socioeconomic health differences) did not decrease when controlled for personality. In this Dutch sample of younger people, personality appeared not to be a driving force for socioeconomic differences in health care use. Findings thus do not support the personality-related, indirect selection perspective on the explanation of socioeconomic differences in health.

Is it better to drive with one foot or with two feet? Although two-foot driving has fostered interminable debate in the media, no scientific and systematic research has assessed this issue and federal and local state governments have provided no answers. The current study compared traditional unipedal (one-foot driving, using the right foot to control the accelerator and the brake pedal) with bipedal (two-foot driving, using the right foot to control the accelerator and the left foot to control the brake pedal) responses to a visual stimulus in a driving simulator study. Each of 30 undergraduate participants drove in a simulated driving scenario. They responded to a STOP sign displayed on the centre of the screen by bringing their vehicle to a complete stop. Brake RT was shorter under the bipedal condition, while throttle RT showed advantage under the unipedal condition. Stopping time and distance showed a bipedal advantage, however. We discuss further limitations of the current study and implications in a driving task. Before drawing any conclusions from the simulator study, further on-road driving tests are necessary to confirm these obtained bipedal advantages. Practitioner Summary: Traditional unipedal (using the right foot to control the accelerator and the brake pedal) with bipedal (using the right foot to control the accelerator and the left foot to control the brake pedal) responses to a visual stimulus in a driving simulator were compared. Our results showed a bipedal advantage. Promotion: Although two-foot driving has fostered interminable debate in the media, no scientific and systematic research has assessed this issue and federal and local state governments have provided no answers.

We analyzed 700 million words, phrases, and topic instances collected from the Facebook messages of 75,000 volunteers, who also took standard personality tests, and found striking variations in language with personality, gender, and age. In our open-vocabulary technique, the data itself drives a comprehensive exploration of language that distinguishes people, finding connections that are not captured with traditional closed-vocabulary word-category analyses. Our analyses shed new light on psychosocial processes yielding results that are face valid (e.g., subjects living in high elevations talk about the mountains), tie in with other research (e.g., neurotic people disproportionately use the phrase 'sick of' and the word 'depressed'), suggest new hypotheses (e.g., an active life implies emotional stability), and give detailed insights (males use the possessive 'my' when mentioning their 'wife' or 'girlfriend' more often than females use 'my' with 'husband' or 'boyfriend'). To date, this represents the largest study, by an order of magnitude, of language and personality.

Pre- and posttraining data from 36 participants (mean age ± SD, 46±11y; 30 women) who received training and 6 participants (mean age ± SD, 48±13y; 5 women) who did not receive training (control group) were compared. Five hours of driving training in a simulator. Performance on a road test at pre- and posttraining. Secondary outcome measures were performance on visual, physical, and cognitive tests. Overall, no significant differences were observed between the training and control groups before and after training. However, 4 of the 7 participants in the training group who failed the road test at pretraining passed posttraining, while the only participant in the control group who failed at pretraining still failed at posttraining. The training group also improved on perception of red and colored numbers, the Paced Auditory Serial Addition Test, and the dot cancellation test of the Stroke Driver Screening Assessment battery and reported less fatigue. These improvements were most pronounced among those with an EDSS score between 3 and 7. This pilot study demonstrates the potential of using a simulator to improve driving-related visual, cognitive, and on-road skills in individuals with RRMS, particularly those with an EDSS score >3. Future randomized controlled trials with adequate power are needed to expand this field of study. Copyright © 2014 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

2017-02-01

Recognizing the clinical importance and safety and well-being implications for the population, a multidisciplinary team has been researching older drivers and driving cessation issues for more than 15 years. Using empirical approaches, the team has explored quality of life and participation outcomes related to driving and nondriving for older people and has developed interventions to improve outcomes after driving cessation. The team members represent occupational therapists, medical practitioners, and clinical and neuropsychologists. While building the evidence base for driving- and driving cessation-related clinical practice, the researchers have also had first-hand experiences of interruptions to their own or parents' driving; involvement of older family members in road crashes; and provision of support during family members' driving assessment and cessation. This has led to reflection on their understandings and re-evaluation and refocusing of their perspectives in driving cessation research. This work will share the narratives of the authors and note their developing perspectives and foci within research as well as their clinical practice. Personal reflections have indicated the far-reaching implications for older drivers and family members of involvement in road crashes: the potential for interruptions to driving as a time for support and future planning and the conflicting and difficult roles of family members within the driving cessation process. Overall the lived, personal experience of the authors has reinforced the complex nature of driving and changes to driving status for the driver and their support team and the need for further research and support. © The Author 2016.

Self-Tracking, Social Media and Personal Health Records for Patient Empowered Self-Care. Contribution of the IMIA Social Media Working Group.

PubMed

Paton, C; Hansen, M; Fernandez-Luque, L; Lau, A Y S

2012-01-01

This paper explores the range of self-tracking devices and social media platforms used by the self-tracking community, and examines the implications of widespread adoption of these tools for scientific progress in health informatics. A literature review was performed to investigate the use of social media and self-tracking technologies in the health sector. An environmental scan identified a range of products and services which were used to exemplify three levels of self-tracking: self-experimentation, social sharing of data and patient controlled electronic health records. There appears to be an increase in the use of self-tracking tools, particularly in the health and fitness sector, but also used in the management of chronic diseases. Evidence of efficacy and effectiveness is limited to date, primarily due to the health and fitness focus of current solutions as opposed to their use in disease management. Several key technologies are converging to produce a trend of increased personal health surveillance and monitoring, social connectedness and sharing, and integration of regional and national health information systems. These trends are enabling new applications of scientific techniques, from personal experimentation to e-epidemiology, as data gathered by individuals are aggregated and shared across increasingly connected healthcare networks. These trends also raise significant new ethical and scientific issues that will need to be addressed, both by health informatics researchers and the communities of self-trackers themselves.

Beliefs about dangerousness of people with mental health problems: the role of media reports and personal exposure to threat or harm.

Reavley, N J; Jorm, A F; Morgan, A J

2016-09-01

To assess the associations between beliefs about the dangerousness of people with mental health problems and exposure to media reports of violence or personal experiences of fear, threat or harm. Telephone interviews were carried out with 5220 Australians aged 18+. Respondents heard a vignette of a person with depression or early schizophrenia and were asked whether they believed him to be dangerous. Other questions covered past 12-month recall of media reports of violence and mental health problems, contact with and experiences of fear, threat or harm by people with mental health problems. Multinomial logistic regression was used to assess the associations between beliefs about dangerousness and media and these types of contact with people with mental health problems. For the early schizophrenia vignette, recall of media reports and having felt afraid of someone were associated with beliefs about dangerousness. For the depression vignette, media reports about violence and mental health problems or the experiences of feeling afraid or having been threatened or harmed were not strongly associated with beliefs about dangerousness. For both vignettes, knowing someone with a mental health problem and having a higher level of education were associated with less belief in dangerousness. Media reports may play a greater role in forming attitudes in low prevalence disorders and further efforts to reduce any adverse impact of media reporting should focus on these disorders. The study also supports the effectiveness of contact with people with mental health problems in reducing beliefs about dangerousness.

Toward a deeper characterization of the social phenotype of Williams syndrome: The association between personality and social drive.

Ng, Rowena; Järvinen, Anna; Bellugi, Ursula

2014-08-01

Previous research has robustly established a Williams syndrome (WS) specific personality profile, predominantly characterized a gregarious, people-oriented, and tense predisposition. Extending this work, the aims of the current, cross-sectional study were two-fold: (1) to elucidate the stability of personality characteristics in individuals with WS and typically developing (TD) comparisons across development, and (2) to explore the personality attributes that may be related to the respective profiles of social functioning characterizing the two groups, which is currently poorly understood. The sample comprised of participants with WS and TD matched on chronological age. The test battery included the Multidimensional Personality Questionnaire (MPQ) and the Salk Institute Sociability Questionnaire (SISQ), an index of real-life social behavior. The main results showed that compared to the TD individuals, the WS group were consistently rated higher in Social Closeness, and this trait remained stable across development. Interpersonal behaviors were best predicted by Social Closeness in WS and by Social Potency in TD. Regression analysis highlighted that while a central motive underlying the increased drive toward social interaction in individuals with WS pertains to a desire to form affectionate relationships, TD individuals by contrast are motivated by a desire to exert social influence over others (leadership, social-dominance) and Well-Being (positive emotional disposition). In conclusion, these findings provide novel insight into social motivational factors underpinning the WS social behavior in real life, and contribute toward a deeper characterization of the WS affiliative drive. We suggest potential areas for behavioral intervention targeting improved social adjustment in individuals with WS. Copyright © 2014 Elsevier Ltd. All rights reserved.

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

This research tested the association between the Dark Triad and driving aggression as well as the incremental validity of the Dark Triad in predicting aggressive driving and the mediation role of the Dark Triad in the relationship between Big Five personality factors and aggressive driving. 274 undergraduate students in Study 1 and 95 amateur drivers in Study 2 completed measures of the Dark Triad (Machiavellianism, Narcissism and Psychopathy), the Big Five personality factors and the aggressive driving expression. Results showed that all the Dark Triad traits were related to aggressive driving behavior in both Study 1 and Study 2 and that the Dark Triad predicted driving aggression after the effect of the Big five personality factors was controlled, with Psychopathy being the strongest predictor of driving aggression in both Study 1 and Study 2. Machiavellianism and Psychopathy mediated the relationship between Emotional Stability, Agreeableness, Conscientiousness on one hand and aggressive driving on the other hand.

Personal health and consumer informatics. The impact of health oriented social media applications on health outcomes.

PubMed

Gibbons, M C

2013-01-01

The rapid evolution in the world-wide use of Social Media tools suggests the emergence of a global phenomenon that may have implications in the Personal Health and Consumer Health Informatics domains. However the impact of these tools on health outcomes is not known. The goal of this research was to review the randomized controlled trial (RCT) evidence of the impact of health oriented Social Media informatics tools on health outcomes. Evaluations of Social Media consumer health tools were systematically reviewed. Research was limited to studies published in the English language, published in Medline, published in the calendar year 2012 and limited to studies that utilized a RCT methodological design. Two high quality Randomized Controlled Trials among over 600 articles published in Medline were identified. These studies indicate that Social Media interventions may be able to significantly improve pain control among patients with chronic pain and enhance weight loss maintenance among individuals attempting to lose weight. Significantly more research needs to be done to confirm these early findings, evaluate additional health outcomes and further evaluate emerging health oriented Social Media interventions. Chronic pain and weight control have both socially oriented determinants. These studies suggest that understanding the social component of a disease may ultimately provide novel therapeutic targets and socio-clinical interventional strategies.

2013-01-01

We analyzed 700 million words, phrases, and topic instances collected from the Facebook messages of 75,000 volunteers, who also took standard personality tests, and found striking variations in language with personality, gender, and age. In our open-vocabulary technique, the data itself drives a comprehensive exploration of language that distinguishes people, finding connections that are not captured with traditional closed-vocabulary word-category analyses. Our analyses shed new light on psychosocial processes yielding results that are face valid (e.g., subjects living in high elevations talk about the mountains), tie in with other research (e.g., neurotic people disproportionately use the phrase ‘sick of’ and the word ‘depressed’), suggest new hypotheses (e.g., an active life implies emotional stability), and give detailed insights (males use the possessive ‘my’ when mentioning their ‘wife’ or ‘girlfriend’ more often than females use ‘my’ with ‘husband’ or 'boyfriend’). To date, this represents the largest study, by an order of magnitude, of language and personality. PMID:24086296

Social media use is a global phenomenon, with almost two billion people worldwide regularly using these websites. As Internet access around the world increases, so will the number of social media users. Neuroscientists can capitalize on the ubiquity of social media use to gain novel insights about social cognitive processes and the neural systems that support them. This review outlines social motives that drive people to use social media, proposes neural systems supporting social media use, and describes approaches neuroscientists can use to conduct research with social media.

Validation of selected temperament and personality questionnaires for diagnosing drivers' aptitude for safe driving. A Polish study.

Łuczak, Anna; Tarnowski, Adam

2014-09-01

This paper presents the results of a study aimed at validating psychological questionnaires evaluating temperamental and personality features. It discusses their usefulness in diagnosing drivers' aptitude for safe driving and working as professional drivers. Three psychological questionnaires were validated: the Formal Characteristics of Behaviour - Temperament Inventory (FCB-TI), the Eysenck Personality Questionnaire - Revised and Short Scale (EPQ-R (S)) and the Impulsiveness Questionnaire (IVE). Three groups of drivers (n=246) aged 19-75 participated in the study. Group I (professional drivers; n=96) and Group II (nonprofessional drivers; n=75) had never been involved in road crashes, whereas Group III (nonprofessional drivers; n=75) were offenders involved in fatal injury road crashes. Criterion-related validity, Cronbach's alpha and Guttman split-half reliability coefficient were in assessing the psychometric properties of the questionnaires. There were some significant differences between Groups II and III for most traits. However, contrary to expectations, higher Emotional Reactivity, Perseveration and lower Endurance as well as higher Neuroticism, Impulsiveness and Venturesomeness were determined for Group II than for Group III. Additionally, the temperament and personality profile of Group II turned out to be less fitted to the profile of safe drivers than that of Group III, whose profile was actually similar to that of Group I. This seems to result from a high tendency for a positive self-presentation among Group I and Group III (a significantly higher result on the Lie scale in comparison with Group II). The results suggest that if psychological tests are to decide on whether a person may be a professional driver or may drive vehicles, the three questionnaires (FCB-TI, EPQ-R(S) and IVE) do not provide a valid diagnosis of professional drivers' aptitude because of drivers' high tendency for positive self-presentation. However, they can be used in job

To Trust or Not to Trust? What Drives Public Trust in Science in Social Media Engagement

NASA Astrophysics Data System (ADS)

Hwong, Y. L.; Oliver, C.; Van Kranendonk, M. J.

2017-12-01

The erosion of public trust in science is a serious concern today. This climate of distrust has real consequences, from the anti-vaccination movement to climate change denials. The age of social media promises opportunities for improved interactivity between scientists and the public, which experts hope will help improve public confidence in science. However, evidence linking social media engagement and public attitude towards science is scarce. Our study aimed to help fill this gap. We examined Twitter engagement and its impact on public trust in science, focusing on two related science issues: space science and climate change. Our datasets comprised of 10,000 randomly sampled tweets over a month's period in 2016. We used human annotation and machine learning to analyse the tweets. Results revealed the level of distrust was significantly higher in the climate change tweets. However, in the climate change network, people who engaged with science personalities trust science more than those who did not. This difference in trust levels was not present in the space science network. There the two clusters of people displayed similar levels of trust in science. Additionally, we used machine learning to predict the trust labels of tweets and conducted feature analysis to find the properties of trust-inspiring tweets. Our supervised learning algorithm was able to predict trust in science in our sample tweets with 84% accuracy. The strongest predictors of trust in science (as conveyed by tweets) were similarity, presence of URL and authenticity. Contrast this with the findings of our previous study investigating the features of highly engaging space science related social media messages, authenticity is the only feature that also inspires trust. This indicates that what works to promote engagement (e.g. `retweets', `Likes') does not necessarily build trust in science. Social media science communication is not as simple as `we engage, therefore they trust'. We suggest that

The purpose of this report was to describe social behaviors and preferences in adults with epilepsy, including self-reported use of various socialization media (face-to-face and indirect communication) as well as perceived social barriers. 1320 consecutive persons with epilepsy (PWEs) confirmed through inpatient video-EEG monitoring were administered a questionnaire on the day of their first appointment. The questionnaire was designed to assess preferences in socialization practices, frequency of interpersonal contact, use of social media, and perceived barriers to socialization. The survey was developed to gain a better understanding of the socialization behaviors and preferences of our patients for the future development of customized activities in our wellness program. Our sample revealed higher rates of unemployment and single status as compared to the US Census of 2012. With regard socialization however, many were quite social (86% reported daily/weekly communication with friends and family via telephone, 71% saw relatives in person weekly, 68% saw friends weekly, and 65% reported using the computer daily/weekly to socialize). Facebook® was the preferred on-line social media. Indoor/solitary activities were most common with 63% stating they watch TV/read/use the computer followed by physical exercise and spending time outdoors (36%). The frequency of socialization with friends, relatives, and coworkers decreased with the respondents' age and the longer the respondent had carried the diagnosis of epilepsy. Respondents who were taking a greater number of AEDs or were considered refractory were less likely to consider participating in socialization-enhancing activities. The primary barriers to socialization that respondents endorsed were driving prohibition and medication side-effects. Respondents expressed the greatest interest in online support groups or educational programs (31%), office-based support groups (25%), and volunteering (19%). Although the

Within a research project on the role played by human factors on road accidents, the aim of the present study is to evaluate, in young adults, the relationships between driver behaviour and personality factors as well as to assess the neuroendocrine correlates of psychological and behavioural factors investigated. Another aim is to estimate in what measure the performance levels are affected by demographic, psychological and chronobiological variables. It has been found a positive relation between highway code violations, extroversion trait of personality and Sensation Seeking scores, so confirming that this component of personality can affect risky behaviour. Furthermore the subjects more oriented to morningness chronotype were found to be prone to adopt safe driving behaviour. Regarding the relations of the neuroendocrine parameters and driving behaviour a positive correlation was observed between dopamine levels and frequency of driving violations while a negative relationship was found between adrenaline levels and frequency of driving errors. In conclusion the identification of psycho-physiological variables related to driving risky behaviour might be a useful instrument to design traffic safety programs tailored to high risk subjects.

To determine whether an AIDS prevention mass media campaign influenced risk perception, self-efficacy and other behavioural predictors. We used household survey data collected from 2,213 sexually experienced male and female Kenyans aged 15-39. Respondents were administered a questionnaire asking them about their exposure to branded and generic mass media messages concerning HIV/AIDS and condom use. They were asked questions concerning their personal risk perception, self-efficacy, condom effectiveness, condom availability, and their embarrassment in obtaining condoms. Logistic regression analysis was used to determine the impact of exposure to mass media messages on these predictors of behaviour change. Those exposed to branded advertising messages were significantly more likely to consider themselves at higher risk of acquiring HIV and to believe in the severity of AIDS. Exposure to branded messages was also associated with a higher level of personal self-efficacy, a greater belief in the efficacy of condoms, a lower level of perceived difficulty in obtaining condoms and reduced embarrassment in purchasing condoms. Moreover, there was a dose-response relationship: a higher intensity of exposure to advertising was associated with more positive outcomes. Exposure to generic advertising messages was less frequently associated with positive health beliefs and these relationships were also weaker. Branded mass media campaigns that promote condom use as an attractive lifestyle choice are likely to contribute to the development of perceptions that are conducive to the adoption of condom use.

Ego, drives, and the dynamics of internal objects

PubMed Central

Boag, Simon

2014-01-01

This paper addresses the relationship between the ego, id, and internal objects. While ego psychology views the ego as autonomous of the drives, a less well-known alternative position views the ego as constituted by the drives. Based on Freud’s ego-instinct account, this position has developed into a school of thought which postulates that the drives act as knowers. Given that there are multiple drives, this position proposes that personality is constituted by multiple knowers. Following on from Freud, the ego is viewed as a composite sub-set of the instinctual drives (ego-drives), whereas those drives cut off from expression form the id. The nature of the “self” is developed in terms of identification and the possibility of multiple personalities is also established. This account is then extended to object-relations and the explanatory value of the ego-drive account is discussed in terms of the addressing the nature of ego-structures and the dynamic nature of internal objects. Finally, the impact of psychological conflict and the significance of repression for understanding the nature of splits within the psyche are also discussed. PMID:25071640

Characteristics of On-Road Driving by Persons with Central Vision Loss: Learning to Drive with a Bioptic Telescope

2016-01-01

There is limited research on the driving performance and safety of bioptic drivers and even less regarding the driving skills that are most challenging for those learning to drive with bioptic telescopes. This research consisted of case studies of five trainee bioptic drivers whose driving skills were compared with those of a group of licensed bioptic drivers (n=23) while they drove along city, suburban, and controlled-access highways in an instrumented dual-brake vehicle. A certified driver rehabilitation specialist was positioned in the front passenger seat to monitor safety and two backseat evaluators independently rated driving using a standardized scoring system. Other aspects of performance were assessed through vehicle instrumentation and video recordings. Results demonstrate that while sign recognition, lane keeping, steering steadiness, gap judgments and speed choices were significantly worse in trainees, some driving behaviors and skills, including pedestrian detection and traffic light recognition were not significantly different to those of the licensed drivers. These data provide useful insights into the skill challenges encountered by a small sample of trainee bioptic drivers which, while not generalizable because of the small sample size, provide valuable insights beyond that of previous studies and can be used as a basis to guide training strategies.

1998-11-01

Media-based physical activity interventions include a variety of print, graphic, audiovisual, and broadcast media programs intended to influence behavior change. New information technology allows print to be delivered in personalized, interactive formats that may enhance efficacy. Media-based interventions have been shaped by conceptual models from health education, Social Cognitive Theory, the Transtheoretical Model, and Social Marketing frameworks. We reviewed 28 studies of media-based interventions of which seven were mass media campaigns at the state or national level and the remaining 21 were delivered through health care, the workplace, or in the community. Recall of mass-media messages generally was high, but mass-media campaigns had very little impact on physical activity behavior. Interventions using print and/or telephone were effective in changing behavior in the short term. Studies in which there were more contacts and interventions tailored to the target audience were most effective. A key issue for research on media-based physical activity interventions is reaching socially disadvantaged groups for whom access, particularly to new forms of communication technology, may be limited. There is a clear need for controlled trials comparing different forms and intensities of media-based physical activity interventions. Controlled studies of personalized print, interactive computer-mediated programs, and web-based formats for program delivery also are needed. The integration of media-based methods into public and private sector service delivery has much potential for innovation.

U.s. State and federal laws targeting distracted driving.

PubMed

Catherine Chase, J D

2014-01-01

Distracted driving has burgeoned with the proliferation of cell phones, global positioning systems and other in-vehicle and personal electronic devices. Annually more than 3,300 people are killed and an additional 400,000 are injured in the United States in distracted driving crashes. The United States (U.S.) federal and state governments have responded to this public health problem with policies and laws; however, a more comprehensive and more effective approach is still needed. Some restrictions on the use of electronic devices while driving by federal employees and some voluntary guidelines and recommendations have been issued. Public opinion polls show support for addressing the issue of distracted driving with state laws. The majority of states have laws banning text messaging while driving and prohibiting the use of an electronic device by teenage or novice drivers. Some states prohibit all drivers from using a hand-held cellphone. Currently no state has a total ban on the use of personal electronic devices while driving. Successful past traffic safety campaigns changing driver behavior have demonstrated the necessity to adopt a "three Es" approach of Enactment of a law, Education of the public about the law, and rigorous Enforcement of the law. Experience reveals that this approach, along with future federal regulation of in-vehicle electronic devices and the employment of technology to limit the use of electronic devices while driving, is needed to alter personal behavior in order to reduce distractions and keep drivers focused on the driving task.

Personal reflections on exploring social media in medicine.

PubMed

Thoma, Brent

2015-04-01

Social media is difficult to explain to a physician who has never used it. The medical literature on its pitfalls and abuses has overshadowed its positive applications and made many physicians wary of it. While I was initially reluctant to develop my own presence on social media, since embracing it as a tool for teaching and learning I have developed a different perspective. I see it as a tool that can be used positively or negatively. Much like a megaphone, it can amplify our voice so that the impact of our work can extend beyond the borders of our institutions and countries. Aided by the guidance and support of mentors who used social media before and alongside me, it has helped me to become a more competent, professional, engaged, and impactful physician. Within this article I will share my story to illustrate the many ways that social media can be used to enhance the profession of medicine.

Psychometrics of the Fitness-to-Drive Screening Measure.

PubMed

Classen, Sherrilene; Velozo, Craig A; Winter, Sandra M; Bédard, Michel; Wang, Yanning

2015-01-01

We employed item response theory (IRT), specifically using Rasch modeling, to determine the measurement precision of the Fitness-to-Drive Screening Measure (FTDS), a tool that can be used by caregivers and occupational therapists to help detect at-risk drivers. We examined unidimensionality through the factor structure (how items contribute to the central construct of fitness to drive), rating scale (use of the categories of the rating scale), item/person-level separation (distinguishing between items with different difficulty levels or persons with different ability levels) and reliability, item hierarchy (easier driving items advancing to more difficult driving items), rater reliability, rater effects (severity vs. leniency of a rater), and criterion validity of the FTDS to an on-road assessment, via three rater groups (n = 200 older drivers; n = 200 caregivers; n = 2 evaluators). The FTDS is unidimensional, the rating scale performed well, has good person (> 3.07) and item (> 5.43) separation, good person (> 0.90) and item reliability (> 0.97), with < 10% misfitting items for two rater groups (caregivers and drivers). The intraclass correlation (ICC) coefficient among the three rater groups was significant (.253, p < .001) and the evaluators were the most severe raters. When comparing the caregivers' FTDS rating with the drivers' on-road assessment, the areas under the curve (index of discriminability; caregivers .726, p < .001) suggested concurrent validity between the FTDS and the on-road assessment. Despite limitations, the FTDS is a reliable and accurate screening measure for caregivers to help identify at-risk older drivers and for occupational therapy practitioners to start conversations about driving.

Alcohol consumption and cycling in contrast to driving.

PubMed

Hagemeister, Carmen; Kronmaier, Markus

2017-08-01

In Germany, the legal blood alcohol limit for cyclists is much higher (0.16 percent) than the limit for drivers (0.05 percent) - as long as no crash has occurred. The proportion of police-recorded crashes with personal damage under the influence is higher for cyclists than drivers, and the blood alcohol concentrations are higher for cyclists than drivers. 63 women and 204 men who drive a car and use a bike and drink alcohol participated in the online study. In the sample, cycling under the influence (CUI) was more frequent and was observed more frequently among friends than driving under the influence (DUI). Persons who use a particular vehicle type more often in general and when they visit friends also use it more often after alcohol consumption. Persons who drink alcohol more often cycle more often after alcohol consumption. In all aspects covered, drink cycling was seen as more acceptable and less dangerous than drink driving. Persons who cycle more often under the influence observe drink cycling more often among their friends. They think they are less of a danger to themselves and others when cycling after alcohol consumption, and they agree less with the statement that one should leave one's bike parked after alcohol consumption. The attitudes that drinking is unsafe for one's own driving and that one should leave one's car parked are important predictors of (non-)drink driving. For cycling, the most important predictors are bike use frequency and observing drink cycling among friends. Copyright © 2017 Elsevier Ltd. All rights reserved.

U.S. State and Federal Laws Targeting Distracted Driving

PubMed Central

Catherine Chase, J.D.

2014-01-01

Distracted driving has burgeoned with the proliferation of cell phones, global positioning systems and other in-vehicle and personal electronic devices. Annually more than 3,300 people are killed and an additional 400,000 are injured in the United States in distracted driving crashes. The United States (U.S.) federal and state governments have responded to this public health problem with policies and laws; however, a more comprehensive and more effective approach is still needed. Some restrictions on the use of electronic devices while driving by federal employees and some voluntary guidelines and recommendations have been issued. Public opinion polls show support for addressing the issue of distracted driving with state laws. The majority of states have laws banning text messaging while driving and prohibiting the use of an electronic device by teenage or novice drivers. Some states prohibit all drivers from using a hand-held cellphone. Currently no state has a total ban on the use of personal electronic devices while driving. Successful past traffic safety campaigns changing driver behavior have demonstrated the necessity to adopt a “three Es” approach of Enactment of a law, Education of the public about the law, and rigorous Enforcement of the law. Experience reveals that this approach, along with future federal regulation of in-vehicle electronic devices and the employment of technology to limit the use of electronic devices while driving, is needed to alter personal behavior in order to reduce distractions and keep drivers focused on the driving task.

A comparison between three electronic media and in-person learning for continuing education in physical rehabilitation.

PubMed

Lemaire, Edward; Greene, G

2003-01-01

We produced continuing education material in physical rehabilitation using a variety of electronic media. We compared four methods of delivering the learning modules: in person with a computer projector, desktop videoconferencing, Web pages and CD-ROM. Health-care workers at eight community hospitals and two nursing homes were asked to participate in the project. A total of 394 questionnaires were received for all modalities: 73 for in-person sessions, 50 for desktop conferencing, 227 for Web pages and 44 for CD-ROM. This represents a 100% response rate from the in-person, desktop conferencing and CD-ROM groups; the response rate for the Web group is unknown, since the questionnaires were completed online. Almost all participants found the modules to be helpful in their work. The CD-ROM group gave significantly higher ratings than the Web page group, although all four learning modalities received high ratings. A combination of all four modalities would be required to provide the best possible learning opportunity.

The adoption of social media and social media marketing by dentists in South Africa.

Snyman, L; Visser, J H

2014-07-01

The purpose of the study was to identify and understand social media usage behaviour of dentists in South Africa, in general and in particular as part of their marketing strategy and to consider the potential determinants associated with these behaviours. Dentists who are members of the South African Dental Association were requested to anonymously complete an online questionnaire. Apart from demographic information, respondents were asked to report on their use of social media and their adoption of social media marketing. One-on-one interviews were also conducted with three dentists, to gain a deeper understanding of their adoption of this marketing option. South African dentists have started to embrace social media and 50.2% interact through these channels at least once a day. The most popular social media platforms are GooglePlus and Facebook. Respondents use social media mainly for personal purposes, including staying connected to family and friends.. Only 13.2% of those responding currently use social media as a marketing tool, but the majority (83.5%) predict that such usage will increase in future. Social media marketing is a growing trend and will become more significant in future. Although respondents used social media regularly for personal purposes, most are only now starting to use it as a marketing tool.

Who Multitasks on Smartphones? Smartphone Multitaskers' Motivations and Personality Traits.

PubMed

Lim, Sohye; Shim, Hongjin

2016-03-01

This study aimed to explore the psychological determinants of smartphone multitasking. Smartphone multitasking comprises the following three different subtypes: multitasking with nonmedia activities, cross-media multitasking with nonsmartphone media, and single-device multitasking within the smartphone. The primary motivations for smartphone multitasking were first identified--efficiency, utility, and positive affect--and the ways in which they are associated with the three subtypes were examined; among the primary motivations, efficiency and positive affect predicted the degree of total smartphone-multitasking behavior. The personality traits that are pertinent to all of the primary motivations--need for cognition (NFC) and sensation seeking (SS)--were also investigated. Further analyses revealed that the motivations for and the extent of smartphone multitasking can vary as functions of a user's NFC and SS. In this study, NFC was not only a meaningful predictor of the cognitive needs that drive smartphone multitasking but also increased the likelihood of multitasking through its interaction with SS.

Personality in cyberspace: personal Web sites as media for personality expressions and impressions.

PubMed

Marcus, Bernd; Machilek, Franz; Schütz, Astrid

2006-06-01

This research examined the personality of owners of personal Web sites based on self-reports, visitors' ratings, and the content of the Web sites. The authors compared a large sample of Web site owners with population-wide samples on the Big Five dimensions of personality. Controlling for demographic differences, the average Web site owner reported being slightly less extraverted and more open to experience. Compared with various other samples, Web site owners did not generally differ on narcissism, self-monitoring, or self-esteem, but gender differences on these traits were often smaller in Web site owners. Self-other agreement was highest with Openness to Experience, but valid judgments of all Big Five dimensions were derived from Web sites providing rich information. Visitors made use of quantifiable features of the Web site to infer personality, and the cues they utilized partly corresponded to self-reported traits. Copyright 2006 APA, all rights reserved.

Personality, emotion-related variables, and media pressure predict eating disorders via disordered eating in Lebanese university students.

Disordered eating behaviors are on the rise among youth. The present study investigates psychosocial and weight-related variables as predictors of eating disorders (ED) through disordered eating (DE) dimensions (namely restrained, external, and emotional eating) in Lebanese university students. The sample consisted of 244 undergraduates (143 female) aged from 18 to 31 years (M = 20.06; SD = 1.67). Using path analysis, two statistical models were built separately with restrained and emotional eating as dependent variables, and all possible direct and indirect pathways were tested for mediating effects. The variables tested for were media influence, perfectionism, trait emotional intelligence, and the Big Five dimensions. In the first model, media pressure, self-control, and extraversion predicted eating disorders via emotional eating. In the second model, media pressure and perfectionism predicted eating disorders via restrained eating. Findings from this study provide an understanding of the dynamics between DE, ED, and key personality, emotion-related, and social factors in youth. Lastly, implications and recommendations for future studies are advanced.

Behavioural ratings of self-regulatory mechanisms and driving behaviour after an acquired brain injury.

2014-01-01

To explore whether measurements of self-regulatory mechanisms and cognition predict driving behaviour after an acquired brain injury (ABI). Consecutive follow-up study. At baseline participants included 77 persons with stroke and 32 persons with a traumatic brain injury (TBI), all of whom completed a multidisciplinary driving assessment (MDA). A follow-up cohort of 34 persons that succeeded the MDA was included. Baseline measurements: Neuropsychological tests and measurements of self-regulatory mechanisms (BRIEF-A and UPPS Impulsive Behaviour Scale), driving behaviour (DBQ) and pre-injury driving characteristics (mileage, compensatory driving strategies and accident rates). Follow-up measurements: Post-injury driving characteristics were collected by mailed questionnaires from the participants who succeeded the MDA. A MDA, which included a medical examination, neuropsychological testing and an on-road driving test, was considered in the decision for or against granting a driver's license. Self-regulatory mechanisms and driving behaviour were examined for research purposes only. At baseline, self-regulatory mechanisms were significantly associated to aberrant driving behaviour, but not with neuropsychological data or with the outcome of the on-road driving test. Aspects of self-regulation were associated to driving behaviour at follow-up. It is recommended that self-regulatory measurements should regularly be considered in the driving assessments after ABI.

[Examination of fitness to drive].

Driving a car in public traffic requires a high performance that is often underestimated owing to daily habit. Fitness to drive can be impaired temporary or permanently because of taking substances declining the performance and because of various somatic diseases and psychic disorders. To check the fitness to drive is the responsibility of medical examination in terms of road traffic. This is supposed to be an individual examination corresponding to acknowledged guidelines by an experienced expert in order to keep away dangerous drivers from road traffic but not to reduce excessively the personal freedom of those drivers, who do not endanger road traffic considerably.

A review of national television PSA campaigns for preventing alcohol-impaired driving, 1987-1992.

DeJong, W; Atkin, C K

1995-01-01

We present a content analysis of 137 public service announcements (PSAs) focused on alcohol-impaired driving that aired nationally on U.S. television between 1987 and 1992. Our findings include the following: 1) Most PSAs were intended to reach an undifferentiated general audience, not necessarily those who are at greatest risk for driving after drinking. 2) Most PSAs were designed to create awareness of the problem of alcohol-impaired driving or to promote individual behavior change. 3) More PSAs were developed on the use of designated drivers than on any other subject. 4) About two-thirds of the PSAs included one or more celebrities who speak directly to the audience. Past media campaigns have tended to ignore the fact that people's behavior is profoundly shaped by their environment, which in turn is shaped by public policy. We recommend that future mass media campaigns against alcohol-impaired driving focus on building support for changes in institutional structures, public policy or law that will motivate, support, and sustain the efforts of individuals to alter their behavior. Television PSAs can play an important but somewhat limited role in support of this effort. Greater emphasis will need to be given instead to media advocacy strategies, including paid radio advertising. We further recommend that the principal organizations concerned about alcohol-impaired driving share their plans and develop a common communications strategy that will advance the public policy agenda proposed by the Surgeon General's Workshop on Drunk Driving.

Driving error and anxiety related to iPod mp3 player use in a simulated driving experience.

PubMed

Harvey, Ashley R; Carden, Randy L

2009-08-01

Driver distraction due to cellular phone usage has repeatedly been shown to increase the risk of vehicular accidents; however, the literature regarding the use of other personal electronic devices while driving is relatively sparse. It was hypothesized that the usage of an mp3 player would result in an increase in not only driving error while operating a driving simulator, but driver anxiety scores as well. It was also hypothesized that anxiety scores would be positively related to driving errors when using an mp3 player. 32 participants drove through a set course in a driving simulator twice, once with and once without an iPod mp3 player, with the order counterbalanced. Number of driving errors per course, such as leaving the road, impacts with stationary objects, loss of vehicular control, etc., and anxiety were significantly higher when an iPod was in use. Anxiety scores were unrelated to number of driving errors.

The prospect of using genetic methods to target vector, parasite, and reservoir species offers tremendous potential benefits to public health, but the use of genome editing to alter the shared environment will require special attention to public perception and community governance in order to benefit the world. Public skepticism combined with the media scrutiny of gene drive systems could easily derail unpopular projects entirely, especially given the potential for trade barriers to be raised against countries that employ self-propagating gene drives. Hence, open and community-guided development of thoughtfully chosen applications is not only the most ethical approach, but also the most likely to overcome the economic, social, and diplomatic barriers. Here we review current and past attempts to alter ecosystems using biological methods, identify key determinants of social acceptance, and chart a stepwise path for developers towards safe and widely supported use.

To review updates in how abortion care is depicted and analysed though various media outlets: news, television, film, and social media. A surge in recent media-related abortion research has recognized several notable and emerging themes: abortion in the news media is often inappropriately sourced and politically motivated; abortion portrayal in US film and television is frequently misrepresented; and social media has a new and significant role in abortion advocacy. The portrayal of abortion onscreen, in the news, and online through social media has a significant impact on cultural, personal, and political beliefs in the United States. This is an emerging field of research with wide spread potential impact across several arenas: medicine, policy, public health.

[Driving ability and dementia].

PubMed

Lukas, Albert; Nikolaus, Thorsten

2009-06-01

Physiological changes in cognitive competence in the elderly are clearly different to pathological changes such as dementia. Diagnosing dementia is not to be equated with absolute driving inability. During the course of dementia, the risk of an accident increases significantly. Detailed observation and regular checks serve to determine the appropriate time to hand in the driving licence. The basis of each decision should be a detailed history of the person and his or her immediate family. Attention should be paid to incorrect driving practise, unusual behaviour and uncertainty whilst driving as well as involvement in any accidents. An MMSE score below 24 or a CCT score up to 3 should result in an additional assessment being carried out, e.g. neuro-psychological tests, driving simulator or, if necessary on-road tests performed with specialists. Also helpful is the determination of functional status. Limitations in ADL or IADL function normally indicate an advanced stage of dementia. Due to the progression of the illness, the possibility of handing in the driving licence should be addressed as soon as possible. In this context, it is helpful to consider alternative forms of transportation. Individual wishes and needs must to be balanced against general road safety requirements.

[Driving ability and fitness to drive in people with diabetes mellitus].

PubMed

Seeger, Rolf; Lehmann, Roger

2011-05-01

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).

Increased crash incidence following deployment and veterans' reports of driving difficulty spurred traffic safety research for this population. We conducted an interim analysis on the efficacy of a simulator-based occupational therapy driving intervention (OT-DI) compared with traffic safety education (TSE) in a randomized controlled trial. During baseline and post-testing, OT-Driver Rehabilitation Specialists and one OT-Certified Driver Rehabilitation Specialist measured driving performance errors on a DriveSafety CDS-250 high-fidelity simulator. The intervention group ( n = 13) received three OT-DI sessions addressing driving errors and visual-search retraining. The control group ( n = 13) received three TSE sessions addressing personal factors and defensive driving. Based on Wilcoxon rank-sum analysis, the OT-DI group's errors were significantly reduced when comparing baseline with Post-Test 1 ( p < .0001) and comparing the OT-DI group with the TSE group at Post-Test 1 ( p = .01). These findings provide support for the efficacy of the OT-DI and set the stage for a future effectiveness study.

Coxon, Kristy; Chevalier, Anna; Lo, Serigne; Ivers, Rebecca; Brown, Julie; Keay, Lisa

2015-06-01

To explore and deepen understanding of factors influencing driving exposure for older drivers. Cross-sectional. Baseline data on function and driving exposure from 1 week of driving were evaluated. A convenience sample of 380 drivers aged 75 and older, residing in northwest Sydney, was recruited. Participants were required to be the primary drivers of their own vehicle. Driver function was evaluated using the DriveSafe and DriveAware clinic-based assessments to measure visual attention to the driving environment and awareness of driving ability. Demographic information was obtained through interview. An in-vehicle monitoring device with data logger and GPS receiver, was used to measure driving exposure in 362 of 380 participants' vehicles. Driving exposure outcomes were total distance driven, furthest distance traveled from home, and average trip length. Factors influencing these exposure outcomes were analyzed using generalized linear regression. Drivers typically drove 100 km in local and surrounding areas during the week. Function was predictive of all driving exposure outcomes. Drivers with lower levels of function drove fewer kilometers and took shorter trips closer to home. Age, health status, and personal circumstance (e.g., rural residence) also influenced exposure, but sex did not. Using objective measures, this study provides evidence that function, age, health status, and personal circumstance influence driving exposure of older drivers. Understanding how older people use driving to preserve their independence is important for exploring safe driving strategies for older people. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

Parkinson's disease and issues related to driving.

Uitti, Ryan J

2009-12-01

Driving a motor vehicle represents an important activity associated with personal independence and freedom. Being told that one can no longer drive is itself associated with loss of independence, depression, low self-esteem and reduced activities [1,2]. Patients with Parkinson's disease (PD), therefore, understandably wish to continue to be able to maintain their ability to drive automobiles, motorcycles, airplanes, and boats, etc. The ability to determine if and when a PD patient is no longer fit to drive a motor vehicle is important for maintaining safety for the PD patient and the public. There are numerous requirements for being able to drive a motor vehicle safely. When any of these capacities deteriorate, the ability to drive safely may be lost. This review will concentrate upon common issues that would be peculiar to patients with PD.

Risk-taking and the media.

2011-05-01

In recent years, media formats with risk-glorifying content, such as video games that simulate illegal street racing ("bang and crash" games), films about extreme sports, and risky stunts have emerged as top sellers of the media industry. A variety of recent studies conducted by several researchers revealed that exposure to risk-glorifying media content (e.g., video games that simulate reckless driving, smoking and drinking in movies, or depictions that glorify extreme sports) increases the likelihood that recipients will show increased levels of risk-taking inclinations and behaviors. The present article (1) reviews the latest research on the detrimental impact of risk-glorifying media on risk-taking inclinations (cognitions, emotions, behaviors), (2) puts these findings in the theoretical context of recent sociocognitive models on media effects, and (3) makes suggestions to science and policymakers on how to deal with these effects in the future. © 2010 Society for Risk Analysis.

High-risk driving attitudes and everyday driving violations of car and racing enthusiasts in Ontario, Canada.

2015-01-01

Attitudes and individual difference variables of car and racing enthusiasts regarding high-risk behaviors of street racing and stunt driving have recently been investigated. Positive attitudes toward high-risk driving, personality variables such as driver thrill seeking, and other self-reported risky driving acts were associated with these behaviors. However, probable relationships among high-risk driving tendencies, everyday driving behaviors, and negative road safety outcomes have remained largely unexamined. This study aimed to investigate the associations among car and racing enthusiasts' high-risk driving attitudes, self-reported everyday driving violations (i.e., ordinary and aggressive violations), and self-reported negative outcomes (i.e., collisions and driving offense citations). A web-based survey was conducted with members and visitors of car club and racing websites in Ontario, Canada. Data were obtained from 366 participants. The questionnaire included 4 attitude measures-(1) attitudes toward new penalties for Ontario's Street Racers, Stunt and Aggressive Drivers Legislation; (2) attitudes toward new offenses of stunt driving under the same legislation; (3) general attitudes toward street racing and stunt driving; (4) comparison of street racing with other risky driving behaviors-self-reported driving violations (i.e., ordinary and aggressive violations); self-reported collisions and offense citations; and background and driving questions (e.g., age, driving frequency). Results revealed that attitudes toward stunt driving offenses negatively and general attitudes toward street racing and stunt driving positively predicted ordinary violations, which, in turn, predicted offense citations. Moreover, general attitudes toward street racing and stunt driving positively predicted aggressive violations, which, in turn, predicted offense citations. The findings indicate that positive high-risk driving attitudes may be transferring to driving violations in

PubMed

Dekker, Arne; Thula Koops

2017-09-01

Digital media are used for the purpose of various sexual experiences. In recent years the exchange of erotic text messages or images ("sexting") has gained the attention of academic research and has increasingly been the center of public discussion on sexual boundary violations and violence via digital media. The unwanted forwarding of images to a third party is especially relevant in this respect. In contrast to media reports about sexting as a risk behavior with serious consequences, there is little empirical analysis about the actual sexting practice of adolescents and adults in Germany. This paper is the first to describe sexting behavior of young adults in Germany on the basis of a large representative student sample. Data were collected in 2012 in the course of a nationwide study. Students from 15 universities were asked among other things about their experiences with sending erotic text messages or images, the non-consensual forwarding of images and its consequences. More than half of the student sample reported sending erotic text messages, 26.8% of women and 16.8% of men had sent erotic images to someone, in most cases to their partner. Of the sexters, 2% mentioned that their images had been forwarded to another person without their consent. The results indicate that in Germany sexting is mostly practiced in the context of a romantic relationship. Only a small percentage experience unwanted forwarding of images, and negative consequences are not reported for all incidents; however, this does not relativize the impact of those events implicating serious negative consequences for the involved person.

There are several brain areas known for playing a role in patho-physiology of depression which may lead to suicidal tendencies, are fed by basilar artery. Therefore, the arterial histoarchitecture was studied in the normal and suicide individuals to establish a relationship between the vascular structural changes and depression. 40 post-mortem samples (both sexes) of basilar artery have been collected and were grouped into normal and suicide groups. Samples were measured for arterial, lumen diameter and the thickness of tunica intima, media and adventitia using H & E stained sections. While, Orcein stained sections were used to estimate the volume fraction of elastic fibres, and Van Gieson stained sections to estimate the volume fraction of collagen fibres. The mean thickness of tunica media of basilar artery in suicide individuals (1.08 microns) showed a statistically significant decrease when compared to normal person (1.33 microns). Further, volume fraction of collagen (0.06 mm 3 /mm 3 ) and elastic fibres (0.06 mm 3 /mm 3 ) in suicide persons showed a statistically significant decrease when compared to normal person (collagen fibres 0.08 mm 3 /mm 3 ; elastic fibres 0.09 mm 3 /mm 3 ). This study establishes a probable causative relationship between vascular structural abnormality and depression which may drive the individual to commit suicide.

Smith, Katherine Clegg; Twum, Denise; Gielen, Andrea Carlson

Alcohol in the media influences norms around use, particularly for young people. A recent spate of celebrity arrests for drinking and driving (DUI) has received considerable media attention. We asked whether these newsworthy events serve as teachable moments or problematic social modeling for young women. Qualitative analysis of US media coverage of four female celebrities (Michelle Rodriguez, Paris Hilton, Nicole Richie and Lindsay Lohan) was conducted over the year following their DUI arrest (December 2005 through June 2008). The media sample included five television and three print sources and resulted in 150 print and 16 television stories. Stories were brief, episodic and focused around glamorous celebrity images. They included routine discussion of the consequences of the DUI for the individual celebrities without much evidence of a consideration of the public health dimensions of drinking and driving or possible prevention measures. Our analysis found little material in the media coverage that dealt with preventing injury or promoting individual and collective responsibility for ensuring such protection. Media attention to such newsworthy events is a missed opportunity that can and should be addressed through media advocacy efforts.

What does media use reveal about personality and mental health? An exploratory investigation among German students.

PubMed

Brailovskaia, Julia; Margraf, Jürgen

2018-01-01

The present study aimed to investigate the relationship between personality traits, mental health variables and media use among German students. The data of 633 participants were collected. Results indicate a positive association between general Internet use, general use of social platforms and Facebook use, on the one hand, and self-esteem, extraversion, narcissism, life satisfaction, social support and resilience, on the other hand. Use of computer games was found to be negatively related to these personality and mental health variables. The use of platforms that focus more on written interaction (Twitter, Tumblr) was assumed to be negatively associated with positive mental health variables and significantly positively with depression, anxiety, and stress symptoms. In contrast, Instagram use, which focuses more on photo-sharing, correlated positively with positive mental health variables. Possible practical implications of the present results for mental health, as well as the limitations of the present work are discussed.

"Banned from the streets I have paid to use": an analysis of Australian print media coverage of proposals for passenger and night driving restrictions for young drivers

2005-01-01

Objective: To catalogue arguments that can be anticipated in public debate when passenger and night driving restrictions are being advocated. Design and setting: Frame analysis of all relevant coverage of these topics in Australian print media during the three month period between June and September 2004 when intensive debate on the topic occurred. Main outcome measures: Debating frames used in reports and commentary on passenger and night driving restrictions. Results: There were 52 relevant articles published containing seven distinct frames supporting the restrictions and six opposing them. Overall, more instances of frames supporting the restrictions were published; these mostly focused on the potential for saving lives. Opposition to the restrictions focused largely on their inappropriateness as a road safety measure as well as on the importance of young people's autonomy and freedom. Conclusions: Advocates of passenger and night driving restrictions have a number of arguments available to advance their case; however, it is important to anticipate and address possible counter arguments. Future research should address the saliency of different arguments to the public and key decision makers in government. PMID:16203840

Trends in alcohol-impaired driving in Canada.

2012-09-01

While a general decreasing trend in the number of persons killed in a traffic crash involving a drinking driver has occurred in Canada since the 1980s, it is evident that much of this decrease occurred in the 1990s. Since 2002, less progress has been made as the number of persons killed in crashes involving drinking drivers remains high. To better understand the current situation, this paper describes trends in drinking and driving in Canada from 1998 to 2011 using multiple indicators based on data collected for the Traffic Injury Research Foundation's (TIRF) Road Safety Monitor (RSM), the National Opinion Poll on Drinking and Driving, and trends in alcohol-related crashes based on data collected for TIRF's national Fatality Database in Canada. There has been a continued and consistent decrease in the number of fatalities involving a drinking driver in Canada. This remains true when looking at the number of fatalities involving a drinking driver per 100,000 population and per 100,000 licensed drivers. This decreasing trend is also still apparent when considering the percentage of persons killed in a traffic crash in Canada involving a drinking driver although less pronounced. Data from the RSM further show that the percentage of those who reported driving after they thought they were over the legal limit has also declined. However, regardless of the apparent decreasing trend in drinking driving fatalities and behaviour, reductions have been relatively modest, and fatalities in crashes involving drivers who have consumed alcohol remain high at unacceptable levels.

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

Effects of altruism and burnout on driving behavior of bus drivers.

PubMed

Shi, Xia; Zhang, Liang

2017-05-01

Personality traits predict driving behaviors. However, the mechanism underlying this relationship has not been adequately investigated in professional drivers. The current study investigated the relationship between altruistic personality and aberrant driving behaviors, and the potential role of burnout. A total of 194 bus drivers completed questionnaires including measures of altruism, burnout and aberrant driving behaviors (aggressive violations, ordinary violations, errors, and lapses). The results showed that altruism was negatively correlated with burnout, and with all the four subcategories of aberrant driving behavior. Burnout fully mediated the relationship between altruism and aggressive violations, and partially mediated the relationship between altruism and lapses. These findings can be applied in the bus drivers' selection and interventions for burnout in order to improve the safety of public transport. Copyright © 2017 Elsevier Ltd. All rights reserved.

Driving is often nominated as problematic by individuals with chronic whiplash associated disorders (WAD), yet driving-related performance has not been evaluated objectively. The purpose of this study was to test driving-related performance in persons with chronic WAD against healthy controls of similar age, gender and driving experience to determine if driving-related performance in the WAD group was sufficiently impaired to recommend fitness to drive assessment. Driving-related performance was assessed using an advanced driving simulator during three driving scenarios; freeway, residential and a central business district (CBD). Total driving duration was approximately 15min. Five driving tasks which could cause a collision (critical events) were included in the scenarios. In addition, the effect of divided attention (identify red dots projected onto side or rear view mirrors) was assessed three times in each scenario. Driving performance was measured using the simulator performance index (SPI) which is calculated from 12 measures. z-Scores for all SPI measures were calculated for each WAD subject based on mean values of the control subjects. The z-scores were then averaged for the WAD group. A z-score of ≤-2 indicated a driving failing grade in the simulator. The number of collisions over the five critical events was compared between the WAD and control groups as was reaction time and missed response ratio in identifying the red dots. Seventeen WAD and 26 control subjects commenced the driving assessment. Demographic data were comparable between the groups. All subjects completed the freeway scenario but four withdrew during the residential and eight during the CBD scenario because of motion sickness. All scenarios were completed by 14 WAD and 17 control subjects. Mean z-scores for the SPI over the three scenarios was statistically lower in the WAD group (-0.3±0.3; P<0.05) but the score was not below the cut-off point for safe driving. There were no

Drink-driving is a crime and traffic offences are a common cause of detention in police custody. Legal assessment of alcohol intoxication is based on breath or blood testing. We hypothesize that refusal of breath alcohol testing or inability to perform it can correspond to singular medical characteristics of the detainee, possibly assaulted or injured during the arrest. Our objective was to determine medical characteristics of detainees held in custody for drink-driving. Prospective monocentric study (April-October, 2010) of drink-drive arrestees. Controls were persons aged over 18 detained for other reasons than drink-driving. Data collected concerned persons' characteristics and reported assaults or observed injuries. 223 drivers were tested positive for breath alcohol level and 55 suspected drink-drivers refused or were not able to complete breath test. 2212 consecutively examined persons served as controls. Drink-drive arrestees requested medical examination more rarely (18% and 7%, vs. 43%, P<0.0001) and drivers tested positive for breath alcohol were more frequently alcohol abusers (25% vs. 14%, P<0.0001) than controls. Drivers who did not complete breath test more often reported assaults than those tested positive for breath alcohol (22% vs. 8%, P=0.007). They had more frequent traumatic injuries than those tested positive and than controls (29% vs. 11% and 17%, P=0.003 and 0.02). Only 1% of drink drivers were unfit for detention after medical examination. Physicians need to give attentive care to detained drink-drivers. Special attention should be paid to drink-drivers who refused or were not able to complete breath alcohol measurement. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

In-simulator training of driving abilities in a person with a traumatic brain injury.

This study reports the case of a 23-year-old woman (MC) who sustained a severe traumatic brain injury in 2004. After her accident, her driving license was revoked. Despite recovering normal neuropsychological functions in the following years, MC was unable to renew her license, failing four on-road evaluations assessing her fitness to drive. In hope of an eventual license renewal, MC went through an in-simulator training programme in the laboratory in 2009. The training programme aimed at improving features of MC's driving behaviour that were identified as being problematic in prior on-road evaluations. To do so, proper driving behaviour was reinforced via driving-specific feedback provided during the training sessions. After 25 sessions in the simulator (over a period of 4 months), MC significantly improved various components of her driving. Notably, compared to early sessions, later ones were associated with a reduced cognitive load, less jerky speed profiles when stopping at intersections and better vehicle control and positioning. A 1-year retention test showed most of these improvements were consistent. The learning principles underlying well conducted simulator-based education programmes have a strong scientific basis. A simulator training programme like this one represents a promising avenue for driving rehabilitation. It allows individuals without a driving license to practice and improve their skills in a safe and realistic environment.

Personalized dosimetry with high accuracy is becoming more important because of the growing interests in personalized medicine and targeted radionuclide therapy. Voxel-based dosimetry using dose point kernel or voxel S-value (VSV) convolution is available. However, these approaches do not consider medium heterogeneity. Here, we propose a new method for whole-body voxel-based personalized dosimetry for heterogeneous media with non-uniform activity distributions, which is referred to as the multiple VSV approach. Methods: The multiple numbers (N) of VSVs for media with different densities covering the whole-body density ranges were used instead of using only a single VSV for water. The VSVs were pre-calculated using GATE Monte Carlo simulation; those were convoluted with the time-integrated activity to generate density-specific dose maps. Computed tomography-based segmentation was conducted to generate binary maps for each density region. The final dose map was acquired by the summation of N segmented density-specific dose maps. We tested several sets of VSVs with different densities: N = 1 (single water VSV), 4, 6, 8, 10, and 20. To validate the proposed method, phantom and patient studies were conducted and compared with direct Monte Carlo, which was considered the ground truth. Finally, patient dosimetry (10 subjects) was conducted using the multiple VSV approach and compared with the single VSV and organ-based dosimetry approaches. Errors at the voxel- and organ-levels were reported for eight organs. Results: In the phantom and patient studies, the multiple VSV approach showed significant improvements regarding voxel-level errors, especially for the lung and bone regions. As N increased, voxel-level errors decreased, although some overestimations were observed at lung boundaries. In the case of multiple VSVs ( N = 8), we achieved voxel-level errors of 2.06%. In the dosimetry study, our proposed method showed much improved results compared to the single VSV and

Describe commercially available products and services designed to convey personal health information in emergencies. The search engine Google®, supplemented by print ads, was used to identify companies and organizations that offer relevant products and services to the general market. Disease-specific, health system, and health plan-specific offerings were excluded. Vendor web sites were the primary sources of information, supplemented by telephone and e-mail queries to sales representatives. Perfect inter-rater agreement was achieved. Thirty-nine unique vendors were identified. Eight sell engraved jewelry. Three offer an embossed card or pamphlet. Twelve supply USB drives with various features. Eleven support password-protected web sites. Five maintain national call centers. Available media differed markedly with respect to capacity and accessibility. Quoted prices ranged from a one-time expenditure of $3.50 to an annual fee of $200. Associated features and annual fees varied widely. A wide range of products and services exist to help patients convey personal health information. Health care providers should be familiar with their features, so they can access the information in a disaster or emergency.

This article explicates the theory of drive and describes the development and validation of two measures. A representative set of drive facets was derived from an extensive corpus of human attributes (Study 1). Operationalised using an International Personality Item Pool version (the Drive:IPIP), a three-factor model was extracted from the facets in two samples and confirmed on a third sample (Study 2). The multi-item IPIP measure showed congruence with a short form, based on single-item ratings of the facets, and both demonstrated cross-informant reliability. Evidence also supported the measures’ convergent, discriminant, concurrent, and incremental validity (Study 3). Based on very promising findings, the authors hope to initiate a stream of research in what is argued to be a rather neglected niche of individual differences and non-cognitive assessment.

Social media's prevalence among the professional world is rapidly increasing. Its use among medical personnel-specifically, medical students, resident physicians, and staff physicians-could compromise personal-professional boundaries. Could the acceptance or lack of acceptance of a friend request bias the medical student application process? If friend requests are accepted, then medical students, resident physicians, and staff physicians are provided access to very personal aspects of one another's lives, which may not have been the intent. The question remains whether the separation of one's personal life from work is necessary. Should medical students restrict social media relationships with residents and staff physicians to professional social media networks? The suitability and opportunities of social media among medical professionals is an ongoing issue for research that needs continued evaluation.

Among the numerous factors that contribute to young novice drivers' driving styles, personality characteristics, sociodemographic variables, family atmosphere, and friends' norms are known to have an important impact. However, cross-cultural comparisons are relatively rare in the safety literature concerning young drivers. This study aimed at comparing young drivers from Israel and Queensland (Australia) and examining the contribution of personality, sociodemographic, family and friends' aspects to their driving styles (reckless and careless; hostile and angry; anxious; patient and careful). More specifically, this study examined the associations between young drivers' driving style and their perceptions of separation-individuation, the family climate for road safety, and the safe driving climate among friends. We also examined sociodemographic and driving history variables such as gender, the marital status of parents, and personal exposure to traffic crashes. The study consisted of two samples of male and female young drivers (age 17-22) from Israel (n=160) and Queensland (n=160), who completed a set of valid and reliable self-report questionnaires. Findings indicate that in general, maladaptive driving styles are associated with lower family tendency to engage in promoting road safety, higher pressure and costs of driving with peers, and unhealthier separation-individuation aspects. The opposite is observed for the patient and careful driving style that relates to higher engagement of the family in road safety, lower pressure from friends, and healthier separation-individuation. Some differences were found regarding specific styles between the two samples. In addition, women scored lower than men in the reckless and careless style, and higher (in the Israeli sample) in the anxious as well as the patient and careful styles. Overall, similarities in the associations between the study variables in the samples exceed the differences, and the importance of examining

Gender roles, sex and the expression of driving anger.

The present study investigated the validity of the 25-item Driving Anger Expression Inventory (DAX) as well as the role of sex and gender-roles in relation to the expression of driving anger in a sample of 378 French drivers (males=38%, M=32.9years old). Confirmatory Factor Analysis supported the four-factor structure of the 25-item DAX (Adaptive/Constructive Expression; Use of the Vehicle to Express Anger; Verbal Aggressive Expression and Personal Physical Aggressive Expression) and two of the three aggressive factors were found to have significant positive relationships with driving anger, while adaptive/constructive expression was negatively related to driving anger. Use of the vehicle to express anger was not significantly related to crash involvement, but was significantly related to all other crash-related conditions (traffic tickets, loss of concentration, loss of control of the vehicle, near crash). The presence of feminine traits, but not sex, was predictive of adaptive/constructive behaviours, while masculine traits predicted more frequent verbal aggressive expression, use of the vehicle to express anger, personal physical aggressive expression and total aggressive expression. This finding may account for the inconsistent relationship found between driving anger and sex in previous research. This research also found that the 25-item DAX is a valid tool to measure the expression of driving anger and that the endorsement of masculine traits are related to more aggressive forms of driving anger expression.

Social workers' knowledge, beliefs, and practices regarding driving and dementia.

PubMed

Adler, Geri

2010-01-01

Drivers with dementia present a significant public safety concern. Failure to recognize and address declines in driving skills associated with dementia can have hazardous consequences for the driver and others. A random sample of social workers was surveyed to better understand their knowledge, beliefs, and practices toward drivers with dementia. Six-hundred five social workers completed the questionnaire. Results reported are based on the analyses of the 152 respondents (25.1% of the sample) who indicated that they worked with persons with dementia. Social workers were significantly more likely to address driving if they had seen more clients with dementia, were more knowledgeable about driving-related issues, and believed they should have a strong role in helping persons with dementia and their families deal with mobility concerns. Social workers who reported that driving situations were more difficult to address than other topics were significantly less likely to broach it in their practices. Implications of the findings are discussed.

Driving behaviors and accident risk under lifetime license revocation.

2011-07-01

This study explored the driving behaviors and crash risk of 768 drivers who were under administrative lifetime driver's license revocation (ALLR). It was found that most of the ALLR offenders (83.2%) were still driving and only a few (16.8%) of them gave up driving completely. Of the offenders still driving, 67.6% experienced encountering a police roadside check, but were not detained or ticketed by the police. Within this group, 50.6% continued driving while encountering a police check, 18.0% of them made an immediate U-turn and 9.5% of them parked and exited their car. As to crash risk, 15.2% of the ALLR offenders had at least one crash experience after the ALLR had been imposed. The results of the logistic regression models showed that the offenders' crash risk while under the ALLR was significantly correlated with their personal characteristics (personal income), penalty status (incarceration, civil compensation and the time elapsed since license revocation), annual distance driven, and needs for driving (working, commuting and driving kids). Low-income offenders were more inclined to have a crash while driving under the ALLR. Offenders penalized by being incarcerated or by paying a high civil compensation drove more carefully and were less of a crash risk under the ALLR. The results also showed there were no differences in crash risk under the ALLR between hit-and-run offences and drunk driving offences or for offenders with a professional license or an ordinary license. Generally, ALLR offenders drove somewhat more carefully and were less of a crash risk (4.3 crashes per million km driven) than legal licensed drivers (23.1 crashes per million km driven). Moreover, they seemed to drive more carefully than drivers who were under short-term license suspension/revocation which previous studies have found. Copyright © 2011 Elsevier Ltd.

Limited evidence exists regarding fitness-to-drive for people with the mental health conditions of schizophrenia, stress/anxiety disorder, depression, personality disorder and obsessive compulsive disorder (herein simply referred to as 'mental health conditions'). The aim of this paper was to systematically search and classify all published studies regarding driving for this population, and then critically appraise papers addressing assessment of fitness-to-drive where the focus was not on the impact of medication on driving. A systematic search of three databases (CINAHL, PSYCHINFO, EMBASE) was completed from inception to May 2016 to identify all articles on driving and mental health conditions. Papers meeting the eligibility criteria of including data relating to assessment of fitness-to-drive were critically appraised using the American Academy of Neurology and Centre for Evidence-Based Medicine protocols. A total of 58 articles met the inclusion criteria of driving among people with mental health conditions studied, and of these, 16 contained data and an explicit focus on assessment of fitness-to-drive. Assessment of fitness-to-drive was reported in three ways: 1) factors impacting on the ability to drive safely among people with mental health conditions, 2) capability and perception of health professionals assessing fitness-to-drive of people with mental health conditions, and 3) crash rates. The level of evidence of the published studies was low due to the absence of controls, and the inability to pool data from different diagnostic groups. Evidence supporting fitness-to-drive is conflicting. There is a relatively small literature in the area of driving with mental health conditions, and the overall quality of studies examining fitness-to-drive is low. Large-scale longitudinal studies with age-matched controls are urgently needed in order to determine the effects of different conditions on fitness-to-drive.

Medicolegal assessment of the ability to drive a motor vehicle in persons with epilepsy.

Gube, Monika; Ell, Werner; Schiefer, Johannes; Kraus, Thomas

2010-04-01

Determining whether a patient with epilepsy ought to be allowed to drive a motor vehicle is a challenging matter for the physician. This situation is fraught with medicolegal uncertainties, not just for general practitioners, but also for specialists and occupational health physicians. A case is reported and discussed in the light of a selective review of the literature and the German medicolegal assessment guidelines for the determination of the ability to drive a motor vehicle. The risk associated with driving can be estimated as a function of the type of epilepsy from which the patient suffers and of the frequency of seizures. The expert can then express an opinion on the basis of this assessment, within the framework of the German medicolegal assessment guidelines and the German Driver Licensing Act ("Fahrerlaubnisverordnung"). There is no general duty of physicians to report a patient's unsuitability for driving a motor vehicle, but physicians have a right to report to the authorities that a patient should not be allowed to drive when the patient fails to comply with a recommendation not to drive and when a higher legally protected interest is at risk. The drawbacks of secondary prevention, as illustrated by the case presented here, could be minimized if the treating physician took the patient's occupational history and gave the relevant advice early on in the course of the patient's illness. Likewise, early counseling about driving would lessen the need for physicians to tell the authorities that patients should not drive in cases where the public interest overrides the patient's right to confidentiality.

Driving with diabetes: precaution, not prohibition, is the proper approach.

PubMed

Kohrman, Daniel B

2013-03-01

Safety issues posed by driving with diabetes are primarily related to severe hypoglycemia, yet some public authorities rely on categorical restrictions on drivers with diabetes. This approach is misguided. Regulation of all drivers with diabetes, or all drivers using insulin, ignores the diversity of people with diabetes and fails to focus on the subpopulation posing the greatest risk. Advances in diabetes care technology and understanding of safety consequences of diabetes have expanded techniques available to limit risks of driving with diabetes. New means of insulin administration and blood glucose monitoring offer greater ease of anticipating and preventing hypoglycemia, and thus, limit driving risk for persons with diabetes. So too do less sophisticated steps taken by people with diabetes and the health care professionals they consult. These include adoption and endorsement of safety-sensitive behaviors, such as testing before a drive and periodic testing on longer trips. Overall, and in most individual cases, driving risks for persons with diabetes are less than those routinely tolerated by our society. Examples include freedom to drive in dangerous conditions and lax regulation of drivers in age and medical cohorts with elevated overall rates of driving mishaps. Data linking specific diabetes symptoms or features with driving risk are quite uncertain. Hence, there is much to recommend: a focus on technological advances, human precautions, and identifying individuals with diabetes with a specific history of driving difficulty. By contrast, available evidence does not support unfocused regulation of all or most drivers with diabetes. © 2013 Diabetes Technology Society.

Following Your "Friend": Social Media and the Strength of Adolescents' Parasocial Relationships with Media Personae.

PubMed

Bond, Bradley J

2016-11-01

Social media have permeated the lives of adolescents and may be altering the way that teens engage with their favorite media celebrities and characters. This study surveyed 316 adolescents to examine the relationship between social media surveillance and the strength of adolescents' parasocial relationships (PSRs) with media personae they follow on social media. Results indicated a significant positive relationship between exposure to media personae on Twitter and strength of PSRs. Adolescents who had experienced social interactions with their favorite media personae on Twitter in the form of retweets or responses to tweets had stronger PSRs than adolescents who had no such interactions. The realism of the media personae did not moderate findings as expected. The findings suggest that Twitter provides intimate glimpses into the personal lives of media personae that increase audiences' feelings of connectedness to those celebrities and characters, an important finding given that teens are more likely to learn from media personae with whom they have PSRs.

Media(ted) fabrications: how the science-media symbiosis helped 'sell' cord banking.

PubMed

Michelle, Carolyn

2006-01-01

This paper considers the problematic role of the science-media symbiosis in the dissemination of misleading and emotionally manipulative information regarding services offered by CordBank, New Zealand's only umbilical cord blood banking facility. As this case study illustrates, the growing reliance of health and science reporters on the knowledge capital of medical specialists, biogenetic researchers, and scientists potentially enhances the ability of 'expert' sources to set the agenda for media representations of emerging medical and scientific developments, and may undermine the editorial independence of journalists and editors, many of whom in this case failed to critically evaluate deeply problematic claims regarding the current and future benefits of cord banking. Heavy reliance on established media frames of anecdotal personalization and technoboosterism also reinforced a proscience journalistic culture in which claims by key sources were uncritically reiterated and amplified, with journalistic assessments of the value of cord banking emphasizing potential benefits for individual consumers. It is argued that use of these media frames potentially detracts from due consideration of the broader social, ethical, legal, and health implications of emerging biomedical developments, along with the professional, personal, and increasingly also financial interests at stake in their public promotion, given the growing commercialization of biogenetic technologies.

Media multitasking is associated with symptoms of depression and social anxiety.

PubMed

Becker, Mark W; Alzahabi, Reem; Hopwood, Christopher J

2013-02-01

We investigated whether multitasking with media was a unique predictor of depression and social anxiety symptoms. Participants (N=318) completed measures of their media use, personality characteristics, depression, and social anxiety. Regression analyses revealed that increased media multitasking was associated with higher depression and social anxiety symptoms, even after controlling for overall media use and the personality traits of neuroticism and extraversion. The unique association between media multitasking and these measures of psychosocial dysfunction suggests that the growing trend of multitasking with media may represent a unique risk factor for mental health problems related to mood and anxiety. Further, the results strongly suggest that future research investigating the impact of media use on mental health needs to consider the role that multitasking with media plays in the relationship.

Impulsivity-like Traits and Risky Driving Behaviors among College Students

PubMed Central

Murphy, Elaine M.; Doane, Ashley N.

2017-01-01

The present study examined the predictive effects of five impulsivity-like traits (Premeditation, Perseverance, Sensation Seeking, Negative Urgency, and Positive Urgency) on driving outcomes (driving errors, driving lapses, driving violations, cell phone driving, traffic citations, and traffic collisions). With a convenience sample of 266 college student drivers, we found that each of the impulsivity-like traits was related to multiple risky driving outcomes. Positive Urgency (tendency to act impulsively when experiencing negative affect) was the most robust predictor of risky driving outcomes. Positive Urgency is a relatively newly conceptualized impulsivity-like trait that was not examined in the driving literature previously, suggesting a strong need to further examine its role as a personality trait related to risky driving. These findings generally support the multidimensional assessment of impulsivity-like traits, and they specifically support the addition of Positive Urgency to a list of risk factors for risky driving behaviors.

Safe Driving Climate among Friends (SDCaF): A new scale.

PubMed

Guggenheim, Noga; Taubman-Ben-Ari, Orit

2018-01-01

Reckless driving among young people, especially young men, is a major cause of injury and fatalities the world over. Like other aspects of this age group, young drivers' driving behaviors and norms are influenced by the accepted social discourse of their peers. Yet despite extensive existing knowledge on young drivers, very few studies have dealt specifically with their characteristic friendship relations. This lacuna in the literature may reflect the absence of specific research tools for examining driving with friends. To fill this gap, we conducted a series of studies with 706 young drivers (aged 17-24) of both sexes aimed at developing and validating a multidimensional scale designed to examine the effect of the social relations of adolescents and young adults on their driving. Entitled Safe Driving Climate among Friends (SDCaF), the final scale consists of 19 items, which tap four dimensions of driving with friends: friends' pressure; social costs of driving with friends; communication with friends about driving; and shared commitment to safe driving. The validity of the scale was established by examining associations between its four dimensions and various variables of personality, friendship, and driving. The findings indicate good reliability and validity, with the three variables of resistance to peer influence, self-disclosure, and personal responsibility for safe driving yielding positive associations with the SDCaF dimensions communication and shared commitment to safe driving, and negative associations with the dimensions friends' pressure and social costs. General tendency to respond to social pressure was positively associated with the dimensions of friends' pressure and social costs, and negatively associated with shared commitment to safe driving. Gender differences were also found, with men scoring higher than women on friends' pressure, and lower than women on shared commitment to safe driving. The SDCaF can serve as a research tool, as well as a

Purpose. To compare eye and head movements, lane keeping, and vehicle control of drivers with hemianopic and quadrantanopic field defects with controls, and to identify differences in these parameters between hemianopic and quadrantanopic drivers rated safe to drive by a clinical driving rehabilitation specialist compared with those rated as unsafe. Methods. Eye and head movements and lane keeping were rated in 22 persons with homonymous hemianopic defects and 8 with quadrantanopic defects (mean age, 53 years) who were ≥6 months post-injury and 30 persons with normal fields (mean age, 53 years). All were licensed to drive and were current drivers or aimed to resume driving. Participants drove a 6.3-mile route along non-interstate city roads under in-traffic conditions. Vehicle control was assessed objectively by vehicle instrumentation for speed, braking, acceleration, and cornering. Results. As a group, drivers with hemianopic or quadrantanopic defects drove slower, exhibited less excessive cornering or acceleration, and executed more shoulder movements than the controls. Those drivers with hemianopic or quadrantanopic defects rated as safe also made more head movements into their blind field, received superior ratings regarding eye movement extent and lane position stability, and exhibited less sudden braking and drove faster than those rated unsafe. Conclusions. Persons with hemianopic and quadrantanopic defects rated as safe to drive compensated by making more head movements into their blind field, combined with more stable lane keeping and less sudden braking. Future research should evaluate whether these characteristics could be trained in rehabilitation programs aimed at improving driving safety in this population. PMID:21367969

An optimization framework is used with the aim of optimizing a driving style with respect to these driving factors. A set of polynomial metamodels is constructed to reflect the responses produced in fuel economy by changing the driving factors. The optimization framework is used to develop a real-time feedback system, including visual instructions, to enable drivers to alter their driving styles in responses to actual driving conditions to improve fuel efficiency.

A Survey of the Elderly in Regional Cities on their Attitudes toward Driving and Giving Up Driving

NASA Astrophysics Data System (ADS)

Nihei, Misato; Kamata, Minoru

Elderly drivers are increasing every year in Japan. However, physical depression caused by aging is also a cause of traffic accidents and they will all have to give up driving one day. The aim of this study is to clarify the effects of car dependency and the impact of having to stop driving among the elderly. And to propose alternative transportation options for elderly after having surrendered their driver's licenses. We carried out a questionnaire survey and a focus group interview. During this study, we sent 1338 questionnaires to people over 60 years old in regional cities that included areas with convenient access and inconvenient access to public transit. From our survey, we found that, over half of the elderly drive every day, the older people lower drive frequency. License holder of elderly with feelings of decreased motor skills awareness a decrease in driving ability. Moreover it is clarified that issue of alternative mobility are "mobility devices to maintain social and personal relationships" and "mobility devices as an extension of walking" and "use the existing public transport environment".

The emerging role of social media in urology.

Leveridge, Michael J

2014-01-01

Social media have become so integrated into modern communications as to be universal in our personal and, increasingly, professional lives. Recent examples of social media uptake in urology, and the emergence of data to quantify it, reveal the expansion of conventional communication routes beyond the in-person forum. In every domain of urologic practice, from patient interaction through research to continuing professional development, the move online has unlocked another layer of conversation, dissemination, and, indeed, caveats. Social media have a democratizing effect, placing patients, trainees, practitioners, and thought leaders in the same arena and on equal footing. If uptake of social media in medicine even remotely parallels its rise to ubiquity in other areas, it will only expand and evolve in the coming years. For these reasons, this article presents an overview of the most recent data on the impact and potential complications of social media usage in the urologic community.

Texting while driving: the development and validation of the distracted driving survey and risk score among young adults.

PubMed

Bergmark, Regan W; Gliklich, Emily; Guo, Rong; Gliklich, Richard E

Texting while driving and other cell-phone reading and writing activities are high-risk activities associated with motor vehicle collisions and mortality. This paper describes the development and preliminary evaluation of the Distracted Driving Survey (DDS) and score. Survey questions were developed by a research team using semi-structured interviews, pilot-tested, and evaluated in young drivers for validity and reliability. Questions focused on texting while driving and use of email, social media, and maps on cellular phones with specific questions about the driving speeds at which these activities are performed. In 228 drivers 18-24 years old, the DDS showed excellent internal consistency (Cronbach's alpha = 0.93) and correlations with reported 12-month crash rates. The score is reported on a 0-44 scale with 44 being highest risk behaviors. For every 1 unit increase of the DDS score, the odds of reporting a car crash increases 7 %. The survey can be completed in two minutes, or less than five minutes if demographic and background information is included. Text messaging was common; 59.2 and 71.5 % of respondents said they wrote and read text messages, respectively, while driving in the last 30 days. The DDS is an 11-item scale that measures cell phone-related distracted driving risk and includes reading/viewing and writing subscores. The scale demonstrated strong validity and reliability in drivers age 24 and younger. The DDS may be useful for measuring rates of cell-phone related distracted driving and for evaluating public health interventions focused on reducing such behaviors.

Media representation of personality disorder in Jamaica - public scholarship as a catalyst of health promotion.

PubMed

Hickling, F W; Robertson-Hickling, H A

2013-01-01

To ascertain whether the public scholarship of the epidemiology of personality disorder (PD) in Jamaica prompted a health promotion outcome. A January 2011 to December 2012 trawl of news media articles linking 'PD' to published public scholarship articles on the epidemiology of PD recorded titles and contents of the reports that were culled to capture the emotional responses and psychological defence mechanisms expressed. These were analysed with concomitant social, psychological or behavioural activities occurring in Jamaica, using SPSS version 17 software. Two public scholarship interventions to two major broadsheet newspapers triggered 25 contributed articles, which in turn prompted 160 responses from the public, five commentaries on leading radio stations and four Internet blogs. One hundred and sixty-six (84.2%) of the titles targeted PD in the Jamaican nation; 31 (13.7) articles targeted PD in leaders, athletes, inmates, individuals, families and productivity in Jamaica. One hundred and fifty-five (79.1%) expressed agreement with the scientific epidemiological observations, while 20.9% (n = 41) expressed disagreement. Eighty-two (41.8%) of the responses expressed rationalizations, 47 (24%) were expressions of reaction formation, 27 (13.8%) were in frank denial, while 25 (12.8%) were expressing open acting out responses or blunt projection (15, 7.7%) to the published epidemiology. The difference between 139 (70.9%) popular media responses to contemporary social problems and 57 (29.1%) reports that made no reference to social problems was statistically significant (p < 0.03). The hypothesis that public scholarship reports prompted a popular media response, generating a health promotion outcome linking contemporary social events to this medical research is confirmed.

To help radiation sciences students and professionals understand the implications of and best practices for personal postings on social media Web sites. The authors conducted a survey to capture radiologic science professionals' opinions regarding trends related to using social media for employment, as well as for their personal use. The majority of imaging professionals are mindful of their privacy settings and believe their activity on social media sites reflects on them professionally. Participants in this study noted they maintain high privacy settings. In spite of this, both supervisors and nonsupervisors in this study held opinions about the use of social media in employment decisions that are inconsistent with what can occur in the workplace. Survey respondents did not believe there should be employment sanctions for behaviors that routinely are sanctioned in the workplace. An important message that has emerged from this research is that employees should not only adhere to the strictest privacy settings on their personal social media sites, but they also should be judicious in what they choose to share, with the understanding that nothing posted online is truly private. Supervisors and nonsupervisors should become familiar with their institutional policies regarding the use of social media in the workplace, and supervisors specifically should ensure that they follow institutional policy regarding the use of social media in employment decisions.

Storage media pipelining: Making good use of fine-grained media

NASA Technical Reports Server (NTRS)

Vanmeter, Rodney

1993-01-01

This paper proposes a new high-performance paradigm for accessing removable media such as tapes and especially magneto-optical disks. In high-performance computing the striping of data across multiple devices is a common means of improving data transfer rates. Striping has been used very successfully for fixed magnetic disks improving overall system reliability as well as throughput. It has also been proposed as a solution for providing improved bandwidth for tape and magneto-optical subsystems. However, striping of removable media has shortcomings, particularly in the areas of latency to data and restricted system configurations, and is suitable primarily for very large I/Os. We propose that for fine-grained media, an alternative access method, media pipelining, may be used to provide high bandwidth for large requests while retaining the flexibility to support concurrent small requests and different system configurations. Its principal drawback is high buffering requirements in the host computer or file server. This paper discusses the possible organization of such a system including the hardware conditions under which it may be effective, and the flexibility of configuration. Its expected performance is discussed under varying workloads including large single I/O's and numerous smaller ones. Finally, a specific system incorporating a high-transfer-rate magneto-optical disk drive and autochanger is discussed.

The tragic case of a district nurse killed when a car driven by a man in a hypoglycaemic state struck her while she took her regular evening walk highlights the dangers that can occur when a person with diabetes drives without regard to their condition. The man was later jailed for four and a half years for causing death by dangerous driving having been found criminally responsible for his actions because he failed to control his blood sugar levels during the journey. In this article the authors set out the likely consequences for people with diabetes who fail in their duty to ensure that they are able to drive safely and are unlikely to be affected by the adverse effects of their illness or the medication taken to control it.

A common conception of social media is that the definition of success is a huge number of viewers and followers. While these outcomes not undesirable, they are not the only signs of success. More important than the size of the audience, is how well that audience follows and in turn, propagates the desired message. Dark Snow project has been successful in driving a global conversation about the Greenland ice sheet, not by creating huge numbers of viewers and followers, but due to a significant, and highly motivated, following among media gatekeepers, academic messengers, and social media activists. It's very important that, from the start, the Dark Snow story - that changes in ice sheet albedo may be driving increased melt, was effectively encoded, or "branded", in the project's name - "Dark Snow" - a vivid and easily illustrated visual image. A simple concept that is easy to describe and understand, but profound in implication, has allowed for wide discussion among professionals in science and media, as well as the general public.

Subjective perceptions and perceived needs for dental care in a population can provide important information for policy-makers. This study aimed to assess self-perceived personal oral health status among the Saudi Arabia population who could be accessed through social media. A pre-tested questionnaire for completion online was designed to assess self-perceived oral health via 13 items in 4 domains with weighted scores from 1-3. The questionnaire was uploaded to the Internet and the link to it was made available through popular social networking sites in Saudi Arabia. With respondents recruited by snowball methods a total of 4618 people (57.2% males, 42.8% females) completed the questionnaire. The total mean score for the participants was 23.0 (SD 5.0) (scale range 13-39). Self-perceived oral health was rated as poor by 24.2% of respondents, average by 50.6% and good by 25.2%. Educational level, age and region but not sex were significantly associated with self-perceived oral health.

Transportation issues in industrialized nations play an important role in the lives of most citizens. The acts of flying and driving, especially in the United States, intersect with many peoples' lives on almost a daily basis. Although some larger cities have modern and efficient public transportation systems, many do not, thus placing considerable responsibility on the individual to manage their own transportation needs. A person with epilepsy faces considerable challenges when it comes to transportation. Defining these challenges and understanding how to deal with the person with epilepsy and transportation issues is the focus of this article.

We examined relationships between drive for leanness and perceived media pressure to change appearance, internalization of an ideal physique, exercise frequency, and dieting. Men and women (N=353) completed the Drive for Leanness Scale, the Sociocultural Attitudes Toward Appearance Questionnaire-3, the Eating Attitudes Test-26, and a demographic inventory. Drive for leanness was significantly correlated with athletic internalization (.52), pressure to attain an ideal physique (.25), exercise frequency (.36), and dieting (.25). Structural equation modeling revealed a good fitting model (χ(2)=2.85, p<.241; CFI=.99; NNFI=.98; RMSEA=.04; SRMR=.02) with internalization predicting drive for leanness, which in turn predicted dieting and exercise. Results reveal social/cultural theory helps enhance the understanding of the drive for leanness and its relationship with health-related behavior. Copyright © 2013 Elsevier Ltd. All rights reserved.

2015-05-01

The current study joins efforts devoted to understanding the associations of parents' personality, attitude, and behavior, and to evaluating the added contribution of peers to the driving behavior of young drivers during their solo driving. The study combines data gathered using in-vehicle data recorders from actual driving of parents and their male teen driver with data collected from self-report questionnaires completed by the young drivers. The sample consists of 121 families, who participated in the study for 12 months, beginning with the licensure of the teen driver. The current examination concentrates on the last 3 months of this first year of driving. The experimental design was based on a random control assignment into three treatment groups (with different forms of feedback) and a control group (with no feedback). Findings indicate that the parents' (especially the fathers') sensation seeking, anxiety, and aggression, as well as their risky driving events rate were positively associated with higher risky driving of the young driver. In addition, parents' involvement in the intervention, either by feedback or by training, led to lower risky driving events rate of young drivers compared to the control group. Finally, higher cohesion and adaptability mitigated parents' model for risky driving, and peers norms' of risky driving were associated with higher risk by the teen drivers. We conclude by claiming that there is an unequivocal need to look at a full and complex set of antecedents in parents' personality, attitudes, and behavior, together with the contribution of peers to the young drivers' reckless driving, and address the practical implications for road safety.

Personality, risk aversion and speeding: an empirical investigation.

PubMed

Greaves, Stephen P; Ellison, Adrian B

2011-09-01

Evidence suggests that in addition to demographics, there are strong relationships between facets of drivers' personality (e.g., aggression, thrill-seeking, altruism), aversion to risk and driving behaviour, particularly speeding. However, evidence is muted by the reliance on self-reported driving behaviour, which is thought to not accurately reflect actual driving behaviour. This paper reports on a study of 133 drivers in Sydney, who were asked to complete a short survey to develop their personality and risk aversion profiles and self-reported speeding behaviour. A Global Positioning System (GPS) device was then installed in their vehicle for several weeks as part of a major investigation of driving behaviour from which empirical measures of speeding are derived. Among the most pertinent findings are: (1) the tendency for drivers to both under and over-estimate their propensity to speed, (2) significant heterogeneity in speeding with a small, but notable number of drivers exceeding the limit for more than 20 percent of the distance driven, (3) weak relationships between the personality/risk-aversion measures and actual speeding, and (4) the suggestion that different personality traits appear to influence behaviour in different situations both from self-reported and actual speeding behaviour.

Nighttime driving and fatal crash involvement of teenagers.

PubMed

Williams, A F

1985-02-01

Data from the 1977 National Personal Transportation Survey and from the Fatal Accident Reporting System were used to compute mileage-based fatal crash involvement rates of drivers, by age, sex, and time of day. Teenagers drive less than older drivers but do more of their driving at night. They have much higher numbers of drivers in fatal crashes based on miles driven than do older drivers; their nighttime rates are particularly high. Sixteen year olds, especially males, have by far the highest fatal crash rates per mile, both nighttime and daytime. More widespread adoption of driving curfew laws would very likely produce substantial reductions in fatalities involving 16 yr old drivers.

Social Media Awareness and Implications in Nursing Leadership.

Burton, Candace W; McLemore, Monica R; Perry, Laura; Carrick, Jenny; Shattell, Mona

2016-11-01

Many nursing professionals-may be reluctant to engage in or are confused about appropriate use of social media in a clinical, research, or policy context. To address this issue, we developed a study to enhance nurse leaders' facility with social media in the context of a national professional meeting. This study examined a social media campaign at the 2015 American Academy of Nursing conference. The campaign was intended to bridge the gap between active social media users and nonusers attending the conference. Following a targeted social media campaign at the American Academy of Nursing 2015 Transforming Health, Driving Policy Conference, responses to the conference evaluation questions about social media were reviewed and analyzed. Overall, evaluations were positive about the campaign; however, some conference attendees were not aware of its various components. Despite perceived barriers to its use, there is significant curiosity about social media use among nurse leaders. With the engagement of these leaders, there may be opportunities to enhance social media use at professional meetings and to make broader use of this valuable tool throughout the nursing profession.

Media violence.

PubMed

Cantor, J

2000-08-01

Research on the effects of media violence is not well understood by the general public. Despite this fact, there is an overwhelming consensus in the scientific literature about the unhealthy effects of media violence. Meta-analyses show that media-violence viewing consistently is associated with higher levels of antisocial behavior, ranging from the trivial (imitative violence directed against toys) to the serious (criminal violence), with many consequential outcomes in between (acceptance of violence as a solution to problems, increased feelings of hostility, and the apparent delivery of painful stimulation to another person). Desensitization is another well-documented effect of viewing violence, which is observable in reduced arousal and emotional disturbance while witnessing violence, the reduced tendency to intervene in a fight, and less sympathy for the victims of violence. Although there is evidence that youth who are already violent are more likely to seek out violent entertainment, there is strong evidence that the relationship between violence viewing and antisocial behavior is bidirectional. There is growing evidence that media violence also engenders intense fear in children which often lasts days, months, and even years. The media's potential role in solutions to these problems is only beginning to be explored, in investigations examining the uses and effects of movie ratings, television ratings, and the V-chip, and the effects of media literacy programs and public education efforts. Future research should explore important individual differences in responses to media violence and effective ways to intervene in the negative effects.

Using music to change mood while driving.

PubMed

van der Zwaag, Marjolein D; Janssen, Joris H; Nass, Clifford; Westerink, Joyce H D M; Chowdhury, Shrestha; de Waard, Dick

2013-01-01

This study investigated whether gradual or abrupt music change towards more calming music is most effective in calming drivers during high-demand driving situations. Twenty-eight participants were subjected to two types of music change (gradual, abrupt) in a within-subject design. First, a relatively happy mood was induced with personally selected music during an eight-minute simulated high-demand drive. The drive then continued and the mood was changed either gradually or abruptly. Subjective results showed successful music mood induction irrespective of gradual or abrupt changes. The results further showed lower skin conductance (less arousal) and more facial corrugator muscle tension (more sadness) during the abrupt music change. Fewer accidents occurred during the abrupt music mood change. To conclude, the results support the abrupt way of changing music type to down-regulate one's mood: during high-demand driving, abrupt changes in music led to more physiological calmness and improved driving performance, and were thus safer and more effective. The current study shows that during high-demand drives, drivers are calmed more effectively using abrupt music changes compared to gradual music changes. This is illustrated by reductions in physiological arousal and improved driving behaviour. Hence, in-car music presentation can be used as a tool to improve driver's mood and behaviour.

An improved method and apparatus for injecting particulate media into the ground for constructing underground permeable reactive barriers, which are used for environmental remediation of subsurface contaminated soil and water. A media injector sub-assembly attached to a triple wall drill string pipe sprays a mixture of active particulate media suspended in a carrier fluid radially outwards from the sub-assembly, at the same time that a mixing fluid is sprayed radially outwards. The media spray intersects the mixing spray at a relatively close distance from the point of injection, which entrains the particulate media into the mixing spray and ensures a uniform and deep dispersion of the active media in the surrounding soil. The media injector sub-assembly can optionally include channels for supplying compressed air to an attached down-the-hole hammer drive assembly for use during drilling.

demographics, cirrhosis details, MHE status, and alcohol cessation patterns, at baseline and at 1 year. Drivers categorized as unsafe had more crashes and made more illegal turns on the driving simulator than drivers categorized as safe; a higher proportion of subjects with MHE were categorized as unsafe drivers at baseline (16%) than subjects without MHE (7%; P = .02), and at 1-year follow-up (18% vs 0%; P = .02). Alcohol cessation within <1 year and illegal turns during simulator navigation tasks were associated with real-life automobile crashes and MHE in regression analysis; road edge excursions in the simulator were associated with real-life traffic violations. Personal assessment of driving skills improved after each simulation episode. In a study of 205 patients with cirrhosis, we associated results from driving simulation tests with real-life driving records and MHE. Traffic safety counseling should focus on patients with cirrhosis who recently quit consuming alcohol and perform poorly on driving simulation. Copyright © 2016 AGA Institute.

Profiling drunk driving recidivists in Denmark.

PubMed

Møller, Mette; Haustein, Sonja; Prato, Carlo Giacomo

2015-10-01

Drunk drivers are a menace to themselves and to other road users, as drunk driving significantly increases the risk of involvement in road accidents and the probability of severe or fatal injuries. Although injuries and fatalities related to road accidents have decreased in recent decades, the prevalence of drunk driving among drivers killed in road accidents has remained stable, at around 25% or more during the past 10 years. Understanding drunk driving, and in particular, recidivism, is essential for designing effective countermeasures, and accordingly, the present study aims at identifying the differences between non-drunk drivers, drunk driving non-recidivists and drunk driving recidivists with respect to their demographic and socio-economic characteristics, road accident involvement and other traffic and non-traffic-related law violations. This study is based on register-data from Statistics Denmark and includes information from 2008 to 2012 for the entire population, aged 18 or older, of Denmark. The results from univariate and multivariate statistical analyses reveal a five year prevalence of 17% for drunk driving recidivism, and a significant relation between recidivism and the drunk drivers' gender, age, income, education, receipt of an early retirement pension, household type, and residential area. Moreover, recidivists are found to have a higher involvement in alcohol-related road accidents, as well as other traffic and, in particular, non-traffic-related offences. These findings indicate that drunk driving recidivism is more likely to occur among persons who are in situations of socio-economic disadvantage and marginalisation. Thus, to increase their effectiveness, preventive measures aiming to reduce drunk driving should also address issues related to the general life situations of the drunk driving recidivists that contribute to an increased risk of drunk driving recidivism.

Fuel consumption for various driving styles in conventional and hybrid electric vehicles: Integrating driving cycle predictions with fuel consumption optimization

Here, improving fuel economy and lowering emissions are key societal goals. Standard driving cycles, pre-designed by the US Environmental Protection Agency (EPA), have long been used to estimate vehicle fuel economy in laboratory-controlled conditions. They have also been used to test and tune different energy management strategies for hybrid electric vehicles (HEVs). This paper aims to estimate fuel consumption for a conventional vehicle and a HEV using personalized driving cycles extracted from real-world data to study the effects of different driving styles and vehicle types on fuel consumption when compared to the estimates based on standard driving cycles. To domore » this, we extracted driving cycles for conventional vehicles and HEVs from a large-scale U.S. survey that contains real-world GPS-based driving records. Next, the driving cycles were assigned to one of three categories: volatile, normal, or calm. Then, the driving cycles were used along with a driver-vehicle simulation that captures driver decisions (vehicle speed during a trip), powertrain, and vehicle dynamics to estimate fuel consumption for conventional vehicles and HEVs with power-split powertrain. To further optimize fuel consumption for HEVs, the Equivalent Consumption Minimization Strategy (ECMS) is applied. The results show that depending on the driving style and the driving scenario, conventional vehicle fuel consumption can vary widely compared with standard EPA driving cycles. Specifically, conventional vehicle fuel consumption was 13% lower in calm urban driving, but almost 34% higher for volatile highway driving compared with standard EPA driving cycles. Interestingly, when a driving cycle is predicted based on the application of case-based reasoning and used to tune the power distribution in a hybrid electric vehicle, its fuel consumption can be reduced by up to 12% in urban driving.

Design We tested the effect of different media platforms (e-mail, Facebook, paid Facebook and Twitter), CME topics, and different “hooks” (e.g., Q&A, clinical pearl and best evidence) on driving clicks to a landing site featuring non-industry sponsored CME. We modelled the effects of social media platform, CME topic, and hook using negative binomial regression on clicks to a single landing site. We used clicks to landing site adjusted for exposure and message number to calculate rate ratios. To understand how physicians interact with CME content on social media, we also conducted interviews with 10 physicians. Setting The National Physicians Alliance (NPA) membership. Participants NPA e-mail recipients, Facebook followers and friends, and Twitter followers. Main Outcomes and Measures Clicks to the NPA’s CME landing site. Results On average, 4,544 recipients received each message. Messages generated a total of 592 clicks to the landing site, for a rate of 5.4 clicks per 1000 recipients exposed. There were 5.4 clicks from e-mail, 11.9 clicks from Facebook, 5.5 clicks from paid Facebook, and 6.9 clicks from Twitter to the landing site for 1000 physicians exposed to each of 4 selected CME modules. A Facebook post generated 2.3x as many clicks to the landing site as did an e-mail after controlling for participant exposure, hook type and CME topic (p<0.001). Twitter posts (p = 0.13) and paid Facebook posts (p = 0.06) were not statistically different from e-mail in generating clicks to the landing site. Use of different hooks to engage physicians had no impact on clicks to the landing site. Interviews with physicians suggested that social media might not be a preferred vehicle for disseminating CME.

Objective To describe the use of social media during the antepartum and postpartum periods among first-time African American mothers and their support persons. Design A qualitative critical ethnographic research design within the contexts of Family Life Course Development Theory and Black Feminist Theory. Setting Participants were recruited from community-based, public health, and home visiting programs. Participants A purposive sample was recruited, consisting of 14 pregnant African American women and eight support persons. Methods Pregnant and postpartum African American women and their support persons were interviewed separately during the antepartum and postpartum periods. Data were analyzed thematically. Results Participants frequently used social media for educational and social support and searched the internet for perinatal and parenting information. Most participants reported using at least one mobile application during their pregnancies and after giving birth. Social media were typically accessed through smartphones and/or computers using different websites and applications. While participants gleaned considerable information about infant development from these applications, they had difficulty finding and recalling information about infant feeding. Conclusion Social media are an important vehicle to disseminate infant feeding information; however, they are not currently being used to full potential. Our findings suggest that future interventions geared towards African American mothers and their support persons should include social media approaches. The way individuals gather, receive, and interpret information is dynamic. The increasing popularity and use of social media platforms offers the opportunity to create more innovative, targeted mobile health interventions for infant feeding and breastfeeding promotion.

Steps in using social media include creating a personal profile, sharing products such as newsletters or publications, and locating volunteer and job opportunities. Learning skills to use social media effectively is important to advancing careers and to the expansion of the public health workforce.

A three-dimensional model for lubricant depletion under sliding condition on bit patterned media of hard disk drives

NASA Astrophysics Data System (ADS)

Wu, Lin

2018-05-01

In this paper, we model the depletion dynamics of the molecularly thin layer of lubricants on a bit patterned media disk of hard disk drives under a sliding air bearing head. The dominant physics and consequently, the lubricant depletion dynamics on a patterned disk are shown to be significantly different from the well-studied cases of a smooth disk. Our results indicate that the surface tension effect, which is negligible on a flat disk, apparently suppresses depletion by enforcing a bottleneck effect around the disk pattern peak regions to thwart the migration of lubricants. When the disjoining pressure is relatively small, it assists the depletion. But, when the disjoining pressure becomes dominant, the disjoining pressure resists depletion. Disk pattern orientation plays a critical role in the depletion process. The effect of disk pattern orientation on depletion originates from its complex interaction with other intermingled factors of external air shearing stress distribution and lubricant particle trajectory. Patterning a disk surface with nanostructures of high density, large height/pitch ratio, and particular orientation is demonstrated to be one efficient way to alleviate the formation of lubricant depletion tracks.

The objective of this study was to assess the current use of social media tools within Canadian otolaryngology-head and neck surgery (OHNS) programs and to assess the interest within these programs to integrate social media for networking, social, and educational programs. A prospective study from September 2013 to February 2014 was performed involving residents and faculty in Canadian OHNS programs. A 26-item questionnaire was created and sent to staff and resident physicians who met the study inclusion criteria using an online survey tool (http://surveymonkey.com). There were 101 respondents for a 10% response rate. More than half (58.4%) of respondents reported use of social media for personal and/or professional matters. Residents and junior faculty physicians 39 years and younger were more likely to have social media accounts and used them more frequently than their older counterparts. Among staff physicians, pediatric otolaryngologists had the highest rate of use, and otologists exhibited the lowest rate. Cellular phones were the most commonly used devices to access social media sites. Fewer than 35% of social media users failed to separate their personal and professional accounts. Although OHNS trainees and practicing physicians identified the potential benefits of social media tools in their specialty, most were unsure how to apply these tools to their practice. Ours is the first study to assess social media use in OHNS. Otolaryngologists are currently using social media; however, their application as a communication and educational tool in otolaryngology remains to be defined.

Professional use of social media by pharmacists.

A recent trend among health care professionals is the use of social media for professional purposes. These rapidly expanding media allow for timely and efficient access to health information, but they also carry the potential for increased liability. There is a paucity of research detailing how health care professionals, specifically pharmacists, use social media. To characterize the use of social media by pharmacists in the Canadian province of Alberta and to identify independent determinants of and perceived barriers to using social media for professional purposes. Data for this mixed-methods study were collected by an online survey in March and April 2014. Alberta pharmacists were invited to participate via e-mail distributed by 2 professional organizations. The survey had 273 respondents. Of these, 226 (82.8%) stated that they had a social media account for either personal or professional purposes, and 138 (61.1%) of these reported using social media for professional purposes, although most respondents used social media predominantly for personal reasons. The most commonly reported social media applications were Facebook and Twitter, accessed primarily via smartphones. Of the 273 respondents, 206 (75.5%) had a Facebook account, and 101 (49.0%) of these used Facebook to some extent for professional purposes. Twitter users (104 [38.1%] of respondents) had a higher rate of professional utilization (57/104 [54.8%]). The most commonly identified barrier to using social media for professional purposes was concern over liability. Positive predictors of use of social media for professional purposes included younger age and fewer years of professional experience. Participants perceived the most beneficial aspect of social media (in professional terms) as connecting with pharmacist colleagues. More than 80% of pharmacists in Alberta reported that they had a social media account, and over half of them reported using their accounts for professional purposes. Although

Personal Digital Branding as a Professional Asset in the Digital Age.

2015-08-25

In recent years, society's rapid adoption of social media has made the boundary between professional and private life nearly indistinguishable. The literature provides guidance on how to demonstrate professionalism via social media platforms. Social media policies within health professions education tend to be legalistic in nature, serving primarily to highlight behaviors students should avoid. One missing element in social media literature is the concept of online invisibility. In this paper, we define personal digital branding, discuss the professional implications of choosing to abstain from social media use, and urge educators to recognize that the personal digital branding may be an emerging asset for young professionals in the twenty-first century.

Drive for muscularity and disordered eating among French adolescent boys: a sociocultural model.

PubMed

Rodgers, Rachel F; Ganchou, Camille; Franko, Debra L; Chabrol, Henri

2012-06-01

The pursuit of muscularity is an important body image concern among boys which has been described within sociocultural models of risk for eating disorders. This study explored a sociocultural model of disordered eating in which drive for thinness and pursuit of muscularity were both pathways to disordered eating among French adolescent boys. A sample of 146 adolescents completed a questionnaire assessing drive for thinness, drive for muscularity, media-ideal internalization, appearance comparison, and sociocultural pressure. The model was a good fit to the data and both drive for thinness and the pursuit of muscularity were related to disordered eating. Furthermore, internalization and appearance comparison mediated the relationships between pressure to increase muscle and both drive for muscularity and drive for thinness. Longitudinal research could help clarify the role of the pursuit of muscularity in the development of disordered eating and extreme body shape changing behaviors. Copyright © 2012 Elsevier Ltd.

Wrong-way driving crashes on French divided roads.

PubMed

Kemel, Emmanuel

2015-02-01

The objective of divided roads is to increase users' safety by posting unidirectional traffic flows. It happens however that drivers proceed in the wrong direction, endangering themselves as well as other users. The crashes caused by wrong-way drivers are generally spotlighted by the media and call for public intervention. This paper proposes a characterization of wrong-way driving crashes occurring on French divided road on the 2008-2012 period. The objective is to identify the factors that delineate between wrong-way driving crashes and other crashes. Building on the national injury road crash database, 266 crashes involving a wrong-way driver were identified. Their characteristics (related to timing, location, vehicle and driver) are compared to those of the 22,120 other crashes that occurred on the same roads over the same period. The comparison relies on descriptive statistics, completed by a logistic regression. Wrong-way driving crashes are rare but severe. They are more likely to occur during night hours and on non-freeway roads than other crashes. Wrong-way drivers are older, more likely to be intoxicated, to be locals, to drive older vehicles, mainly passenger cars without passengers, than other drivers. The differences observed across networks can help prioritizing public intervention. Most of the identified WW-driving factors deal with cognitive impairment. Therefore, the specific countermeasures such as alternative road signs should be designed for and tested on cognitively impaired drivers. Nevertheless, WW-driving factors are also risk factors for other types of crashes (e.g. elderly driving, drunk driving and age of the vehicle). This suggests that, instead of (or in addition to) developing WW-driving specific countermeasures, managing these risk factors would help reducing a larger number of crashes.

Talking to Adolescents About Social Media.

Dawson, Rachel S

2017-08-01

I see a large number of adolescents in my clinic with issues related to their social media use. These issues range from lack of sleep, to depression, to cyberbullying, and even sex trafficking, all secondary to constant social media exposure. Pediatricians should ask about social media use when they see children and adolescents who already have access to electronic devices. They should also ask parents about controls that are set in place to monitor social media use, content, and friend connections on those sites. They should ensure that their children know personally everyone they are connected to on social media and that their accounts are always private and not public. This will help reduce many of the issues associated with the potential consequences of social media use. [Pediatr Ann. 2017;46(8):e274-e276.]. Copyright 2017, SLACK Incorporated.

A potential unintended consequence of legalizing recreational marijuana is increased marijuana-related driving impairment. Some states where recreational marijuana is legal have begun implementing interventions to mitigate driving under the influence (DUI) of marijuana, including media campaigns to increase knowledge about DUI laws. However, little is known about the associations between knowledge of DUI laws and marijuana DUI behavior. In this study, we provide new data from a survey of marijuana users in Colorado and Washington to examine associations between marijuana drugged driving and two potential behavioral precursors of marijuana DUI. We also explore other factors that may influence marijuana DUI. Data are from an online survey of marijuana users in Colorado and Washington. Respondents who reported any marijuana use in the past 30 days (n = 865) served as the analytic sample. We examined prevalence of two behavioral outcomes: (1) any driving of a motor vehicle while high in the past year and (2) driving a motor vehicle within 1 hour of using marijuana 5 or more times in the past month. Additional outcomes measuring willingness to drive while high were also assessed. Logistic regressions were used to estimate each outcome as a function of two multi-item scales measuring knowledge of the legal consequences of driving high and perceptions that driving while high is not safe. Additional covariates for potential confounders were included in each model. Prevalence of past-year driving while under the influence of marijuana was 43.6% among respondents. The prevalence of driving within 1 hour of using marijuana at least 5 times in the past month was 23.9%. Increased perception that driving high is unsafe was associated with lower odds of past-year marijuana DUI (OR = 0.31, P < 0.01) and lower past-month odds of driving 5 or more times within 1 hour of using marijuana (OR = 0.26, P < 0.01). Increased knowledge of marijuana DUI laws was also associated with lower

2007-02-01

The psychosocial development of children and the youth today is embedded in a media society. Socialization is understood as an interaction between the individual and its environment. Media are used to accomplish developmental tasks and media literacy has become a developmental task in itself. The presence of media in all social subsystems of every day life alters the general socialization processes, like the integration into peergroups or the detaching from the parents. Media can play the role of resources or the role of risk factors for the development. Empirical research shows that children's access to media is more and more enhanced and an increasing amount of time is spent with screen media. Media socialization of the young people takes on the mode of self education, but children are dependent on adults to prevent negative media effects such as Internet addiction. If media usage is part of an environment which is adequat for children's wellbeeing, the psychosocial development will not be affected negatively by the media.

The purpose of this study on driving cessation was to explore the process of coping, decision-making and adaptation through this major life transition. We sought to examine understandings of the emotional responses of drivers and ex-drivers with dementia from the perspective of healthcare providers and family caregivers of persons with dementia. Interviews and focus groups were conducted with several key informant groups: healthcare providers who work with patients with dementia and their families ( N = 10), representatives from organizations that provide services and support for persons with dementia ( N = 6), and family caregivers of drivers and former drivers with dementia ( N = 13). Data analysis involved inductive analytic techniques to generate descriptive and analytic themes from the data. The main themes from the analysis involve the: (1) Loss of independence and disruption to identity connected to emotional responses to driving cessation; (2) Experience of driving cessation as one loss within a series of losses related to dementia; (3) Importance of addressing emotional and identity-related effects in supportive responses to driving cessation; and (4) Support for maintained and adapted roles as a strategy to provide meaning and purpose in the context of driving cessation. Driving cessation can represent a significant disruption to identity, and is closely linked to losses, such as independence, within people's broader experiences of grief and loss associated with dementia. The findings suggest the need for supportive responses that address unique emotion and identity-related aspects of driving cessation for people with dementia and their family caregivers.

Vital signs: drinking and driving among high school students aged ≥16 years - United States, 1991-2011.

PubMed

2012-10-05

Although every state prohibits persons aged <21 years from driving with any measurable amount of blood alcohol, many young persons still drink and drive. Additionally, fatal crash data indicate that most teen drivers with positive (>0.00%) blood alcohol concentrations (BACs) who are involved in fatal crashes have BACs ≥0.08%, the level designated as illegal for adult drivers. CDC analyzed data from the 1991-2011 national Youth Risk Behavior Surveys (YRBS) to describe the trend in prevalence of drinking and driving (defined as driving one or more times when they had been drinking alcohol during the 30 days before the survey) among U.S. high school students aged ≥16 years. The 2011 national YRBS data were used to describe selected subgroup differences in drinking and driving, and 2011 state YRBSs data were used to describe drinking and driving prevalence in 41 states. During 1991-2011, the national prevalence of self-reported drinking and driving among high school students aged ≥16 years declined by 54%, from 22.3% to 10.3%. In 2011, 84.6% of students who drove after drinking also binge drank. Drinking and driving prevalence varied threefold across 41 states, from 4.6% in Utah to 14.5% in North Dakota; higher prevalences were clustered among states in the upper Midwest and along the Gulf Coast. Although substantial progress has been made during the past 2 decades to reduce drinking and driving among teens, in 2011, one in 10 students aged ≥16 years reported driving after drinking during the past 30 days. Most students who drove after drinking alcohol also binge drank. Effective interventions to reduce drinking and driving among teens include enforcement of minimum legal drinking age laws, zero tolerance laws (i.e., no alcohol consumption allowed before driving for persons aged <21 years), and graduated driver licensing systems.

Adapting a Driving Simulator to Study Pedestrians' Street-Crossing Decisions: A Feasibility Study.

Jäger, M; Nyffeler, T; Müri, R; Mosimann, U P; Nef, T

2015-01-01

The decision when to cross a street safely is a challenging task that poses high demands on perception and cognition. Both can be affected by normal aging, neurodegenerative disorder, and brain injury, and there is an increasing interest in studying street-crossing decisions. In this article, we describe how driving simulators can be modified to study pedestrians' street-crossing decisions. The driving simulator's projection system and the virtual driving environment were used to present street-crossing scenarios to the participants. New sensors were added to measure when the test person starts to cross the street. Outcome measures were feasibility, usability, task performance, and visual exploration behavior, and were measured in 15 younger persons, 15 older persons, and 5 post-stroke patients. The experiments showed that the test is feasible and usable, and the selected difficulty level was appropriate. Significant differences in the number of crashes between young participants and patients (p = .001) as well as between healthy older participants and patients (p = .003) were found. When the approaching vehicle's speed is high, significant differences between younger and older participants were found as well (p = .038). Overall, the new test setup was well accepted, and we demonstrated that driving simulators can be used to study pedestrians' street-crossing decisions.

Teen Drivers' Perceptions of Inattention and Cell Phone Use While Driving.

McDonald, Catherine C; Sommers, Marilyn S

2015-01-01

Inattention to the roadway, including cell phone use while driving (cell phone calls, sending and reading texts, mobile app use, and Internet use), is a critical problem for teen drivers and increases risk for crashes. Effective behavioral interventions for teens are needed in order to decrease teen driver inattention related to cell phone use while driving. However, teens' perceptions of mobile device use while driving is a necessary component for theoretically driven behavior change interventions. The purpose of this study was to describe teen drivers' perceptions of cell phone use while driving in order to inform future interventions to reduce risky driving. We conducted 7 focus groups with a total of 30 teen drivers, ages 16-18, licensed for ≤ 1 year in Pennsylvania. The focus group interview guide and analysis were based on the Theory of Planned Behavior, identifying the attitudes, perceived behavioral control, and norms about inattention to the roadway. Directed descriptive content analysis was used to analyze the focus group interviews. All focus groups were coded by 2 research team members and discrepancies were reconciled. Themes were developed based on the data. Teens had a mean age of 17.39 (SD = 0.52), mean length of licensure of 173.7 days (SD = 109.2; range 4-364), were 50% male and predominately white (90%) and non-Hispanic (97%). From the focus group data, 3 major themes emerged: (1) Recognizing the danger but still engaging; (2) Considering context; and (3) Formulating safer behaviors that might reduce risk. Despite recognizing that handheld cell phone use, texting, and social media app use are dangerous and distracting while driving, teens and their peers often engaged in these behaviors. Teens described how the context of the situation contributed to whether a teen would place or answer a call, write or respond to a text, or use a social media app. Teens identified ways in which they controlled their behaviors, although some still drew

In recent years, society’s rapid adoption of social media has made the boundary between professional and private life nearly indistinguishable. The literature provides guidance on how to demonstrate professionalism via social media platforms. Social media policies within health professions education tend to be legalistic in nature, serving primarily to highlight behaviors students should avoid. One missing element in social media literature is the concept of online invisibility. In this paper, we define personal digital branding, discuss the professional implications of choosing to abstain from social media use, and urge educators to recognize that the personal digital branding may be an emerging asset for young professionals in the twenty-first century.

New media, old media: The technologies of international development

1986-09-01

The research, theory and practice of educational technology over the past 75 years provide convincing evidence that this process offers a comprehensive and integrated approach to solving educational and social problems. The use of media and technology in development has shifted from an emphasis on mass media to personal media. A variety of electronic delivery systems are being used and are usually coordinated by centralized governmental agencies. There are no patterns of use since the problems vary and the medium used is responsive to the problem. Computers are used most frequently and satellite telecommunication networks follow. The effective use of these and other technologies requires a long-term commitment to financial support and training of personnel. The extension model of face-to-face contact still prevails in developing nations whether in agriculture, education or rural development. Low-cost technologies are being used in local projects while major regional and national companies use radio, film and related video technologies. The use of all available and cost-effective media and technologies make possible appropriate communications for specific goals with specific audiences. There appears to be no conflict among proponents of various media formats. Development in education and other sectors has much to gain from old and new communication technologies and has hardly been tapped. Several new educational technology developments are discussed as potential contributors to formal and nonformal education.

Rapid proliferation of mobile technologies in social and healthcare spaces create an opportunity for advancement in research and clinical practice. The application of mobile, personalized technology in healthcare, referred to as mHealth, has not yet become routine in toxicology. However, key features of our practice environment, such as frequent need for remote evaluation, unreliable historical data from patients, and sensitive subject matter, make mHealth tools appealing solutions in comparison to traditional methods that collect retrospective or indirect data. This manuscript describes the features, uses, and costs associated with several of common sectors of mHealth research including wearable biosensors, ingestible biosensors, head-mounted devices, and social media applications. The benefits and novel challenges associated with the study and use of these applications are then discussed. Finally, opportunities for further research and integration are explored with a particular focus on toxicology-based applications.

Is mass media beneficial or not for the information of the general public?

Stavinschi, M.; Mosoia, C.

The International Year of Physics reminds us, among other things, of the way in which Einstein became famous. In spite of all his remarkable scientific results, without the contribution of the press he would not have become so well known in the entire world as he was and continues to be after a century. And he is not the unique example of celebrity due to mass media (see Carl Sagan or Stephen Hawking). In 1969 the first man stepped on the Moon. It was maybe the first cosmic event, which became famous due to a live TV broadcast. Others followed, if we are to mention only the total solar eclipse of 1999 or Venus's transit of last year. Consequently, mass media can make a scientist famous, can also make an event understood and admired and can attract hundreds or maybe millions of people to science. The same mass media can also destroy a personality or an event. We shall give only two examples: the distrust of many people concerning the same Moon landing or the manipulation of millions of people by means of astrology. All this urges us to make a very thorough analysis of the way in which scientific information is communicated to the general public: well done, it can be beneficial; otherwise it may drive the new generations away from research, the understanding of the phenomena, the neglect of the environment and finally from the neglect and the destruction of our own planet.

Because of its adaptation across age groups and populations, social media is being used as a venue for the conduction of research studies. The implications for use of social media to streamline data collection and analyses to understand epidemiologic effects of disease are intriguing. Public access to personalized Internet-based searches and conversations for patients with or at risk for cancer can potentially allow providers to target individuals for earlier interventions and improved outcomes. Although publicly posted, the use of personal information to solicit research participants, implement interventions, or abstract information for research studies raises questions regarding maintaining the ethical conduct of research.

PubMed

Wishart, Darren; Somoray, Klaire; Evenhuis, Amanda

2017-12-01

Introduction Within many industrialized countries, the leading cause of worker fatalities and serious injuries can be attributed to road trauma. In non-occupational research, high levels of sensation seeking personality, and specifically thrill and adventure seeking, have been associated with risky driving behaviors. In work driving literature, high organizational safety climate has been associated with reduced risky driving in work drivers. However, the extent that factors such as safety climate and thrill seeking interact in regard to work driving safety remains unclear, and the current research examined this interaction. Methods A total of 1,011 work drivers from four organizations participated in the research. Surveys were distributed online and hardcopies were sent via mail. The survey included measures of thrill and adventure seeking, safety climate and work-related driving behaviors, as well as questions relating to participant demographics and information about their work driving. Results The results demonstrated that safety climate significantly moderated the effect of thrill and adventure seeking trait on driving errors, driving violations, and driving while fatigued. Conclusion These results suggest that the development of a strong safety climate has the potential to improve work driving safety outcomes by reducing the impact of particular personality traits such as thrill seeking within an organizational context. Practical application To improve work driving safety, organizations and management need to develop strategies to encourage and foster positive work driving safety climate, particularly within work settings that may attract thrill and adventure seeking employees.

Professional Use of Social Media by Pharmacists

PubMed Central

Barry, Arden R; Pearson, Glen J

2015-01-01

Background: A recent trend among health care professionals is the use of social media for professional purposes. These rapidly expanding media allow for timely and efficient access to health information, but they also carry the potential for increased liability. There is a paucity of research detailing how health care professionals, specifically pharmacists, use social media. Objective: To characterize the use of social media by pharmacists in the Canadian province of Alberta and to identify independent determinants of and perceived barriers to using social media for professional purposes. Methods: Data for this mixed-methods study were collected by an online survey in March and April 2014. Alberta pharmacists were invited to participate via e-mail distributed by 2 professional organizations. Results: The survey had 273 respondents. Of these, 226 (82.8%) stated that they had a social media account for either personal or professional purposes, and 138 (61.1%) of these reported using social media for professional purposes, although most respondents used social media predominantly for personal reasons. The most commonly reported social media applications were Facebook and Twitter, accessed primarily via smartphones. Of the 273 respondents, 206 (75.5%) had a Facebook account, and 101 (49.0%) of these used Facebook to some extent for professional purposes. Twitter users (104 [38.1%] of respondents) had a higher rate of professional utilization (57/104 [54.8%]). The most commonly identified barrier to using social media for professional purposes was concern over liability. Positive predictors of use of social media for professional purposes included younger age and fewer years of professional experience. Participants perceived the most beneficial aspect of social media (in professional terms) as connecting with pharmacist colleagues. Conclusion: More than 80% of pharmacists in Alberta reported that they had a social media account, and over half of them reported using

Previous studies have separately examined conformity to masculine norms and internalization of body ideals in the media in relation to the drive for muscularity (DM). This study was designed to examine these factors together in relation to DM, and further examine how they may differ in relation to drive for thinness (DT) and drive for leanness (DL). Participants were 284 Australian males between ages 18 and 42. They completed validated measures that assessed DM, DT, DL, male gender role norms, and internalization of body ideals. The findings showed that internalization of body ideals mediated the relationship between masculine role norms and body image in the case of both DM and DL. However, masculine norms and internalization were independent predictors of DT. Our findings contribute to further understanding of the roles that the media and masculine norms have in shaping men's drive for muscularity, leanness, and thinness. Longitudinal research is needed to confirm the nature and direction of these relationships. Copyright © 2015 Elsevier Ltd. All rights reserved.

Shane, Howard C; Albert, Patti Ducoff

2008-09-01

Social and anecdotal reports suggest a predilection for visual media among individuals on the autism spectrum, yet no formal investigation has explored the extent of that use. Using a distributed questionnaire design, parents and caregivers report on time allotted toward media, including observable behaviors and communicative responses. More time was spent engaged with electronic screen media (ESM) than any other leisure activity. Television and movie viewing was more popular than computer usage. Across media platforms, animated programs were more highly preferred. Prevalent verbal and physical imitation was reported to occur during and following exposure to ESM. Clinical implications to strategically incorporate ESM into learning approaches for children with autism spectrum disorders (ASD) are provided.

2017-02-01

Based on the National Highway Traffic Safety Association's (NHTSA) Report, fatalities due to distracted driving are on the rise and the highest proportion of fatalities by age group is the 20-29 year old category. To date little has been done to educate college students about the dangers of distracted driving and engage these students in promoting a safe driving culture. Intervening among college students has the potential for making real-time behavior change, can foster a lifetime of safe driving habits among these students, and can help contribute to a culture of safe driving that can be created and sustained through positive messages from peers. The goals of this study were to develop, implement and evaluate a distracted driving presentation for college students to change knowledge, attitude and behavior on distracted driving. A 30-min, multi-media presentation on distracted driving was presented to 19 colleges and universities, totaling 444 college students (mean age 23.7±7.0 years of age, 61% females, 39% males). Students completed three surveys: prior to the workshop (interview 1), immediately after the workshop (interview 2), and 3 months following the workshop (interview 3). We assessed changes between interview 1 and interview 2 and found 15 of the 15 attitude-knowledge based questions significantly improved after the course. In addition, we assessed changes from interviews 1 and 3, and found 11 of the 15 attitude-knowledge based questions maintained their significance. Responses to behavior related questions at three months were also compared to baseline, and significant improvements were found for 12 of the 14 questions. While this study was successful in improving the short-term attitude-knowledge and behaviors on distracted driving, work is needed to sustain (and evaluate) long-term effects.

Though fatigue and sleepiness at the wheel are well-known risk factors for traffic accidents, many drivers combine extended driving and sleep deprivation. Fatigue-related accidents occur mainly at night but there is no experimental data available to determine if the duration of prior driving affects driving performance at night. Participants drove in 3 nocturnal driving sessions (3-5 am, 1-5 am and 9 pm-5 am) on open highway. Fourteen young healthy men (mean age [+/-SD] = 23.4 [+/-1.7] years) participated Inappropriate line crossings (ILC) in the last hour of driving of each session, sleep variables, self-perceived fatigue and sleepiness were measured. Compared to the short (3-5 am) driving session, the incidence rate ratio of inappropriate line crossings increased by 2.6 (95% CI, 1.1 to 6.0; P<.05) for the intermediate (1-5 am) driving session and by 4.0 (CI, 1.7 to 9.4; P<.001) for the long (9 pm-5 am) driving session. Compared to the reference session (9-10 pm), the incidence rate ratio of inappropriate line crossings were 6.0 (95% CI, 2.3 to 15.5; P<.001), 15.4 (CI, 4.6 to 51.5; P<.001) and 24.3 (CI, 7.4 to 79.5; P<.001), respectively, for the three different durations of driving. Self-rated fatigue and sleepiness scores were both positively correlated to driving impairment in the intermediate and long duration sessions (P<.05) and increased significantly during the nocturnal driving sessions compared to the reference session (P<.01). At night, extended driving impairs driving performances and therefore should be limited.

The rapid pace of motorisation in China has been well documented, as has the large road trauma burden the Chinese citizens are facing as a result. China's unique political system represents an important consideration in helping reduce road trauma, yet political factors have not been previously investigated in this context. Recently, emerging issues on the road involving the adult children of politically powerful families have become a serious social problem in China, and have drawn widespread media and public attention. This study took a novel approach to examining factors associated with risky attitudes and risky road use in China by investigating the economic and political background status of a sample of young Chinese drivers. An online survey was conducted in May 2015 with a sample size of 476 Chinese young drivers from across the country, aged between 18 and 28, including 305 males and 171 females. The results suggest that for participants who reported having a familial political background, more risky driving behaviours were reported among those participants who reported more impact on their life from that political background; while for participants without political background, higher personal income was associated with more risky driving behaviours. The findings are discussed in light of China's political management system and potential education opportunities for young drivers. Copyright © 2016 Elsevier Ltd. All rights reserved.

There is a widespread assumption that risk prediction is the major driver of customer interest in personal genomic testing (PGT). However, some customers may also be motivated by finding out whether their existing diseases have a genetic etiology. We evaluated the impact of an existing medical diagnosis on customer interest in condition-specific results from PGT. Using a prospective online survey of PGT customers, we measured customer interest prior to receiving PGT results for 11 health conditions, and examined the association between interest and personal medical history of these conditions using logistic regression. We analyzed data from 1,538 PGT customers, mean age 48.7 years, 61 % women, 90 % White, and 47 % college educated. The proportion of customers who were 'very interested' in condition-specific PGT varied considerably, from 28 % for ulcerative colitis to 68% for heart disease. After adjusting for demographic and personal characteristics including family history, having a diagnosis of the condition itself was significantly associated with interest in genetic testing for risk of that condition, with odds ratios ranging from 2.07 (95 % CI 1.28-3.37) for diabetes to 19.99 (95 % CI 4.57-87.35) for multiple sclerosis. PGT customers are particularly interested in genetic markers for their existing medical conditions, suggesting that the value of genetic testing is not only predictive, but also explanatory.

The study investigates the knowledge, intentions, and driving behavior of persons prescribed medications that display a warning about driving. It also examines their confidence that they can self-assess possible impairment, as is required by the Australian labeling system. We surveyed 358 outpatients in an Australian public hospital pharmacy, representing a well-advised group taking a range of medications including those displaying a warning label about driving. A brief telephone follow-up survey was conducted with a subgroup of the participants. The sample had a median age of 53.2 years and was 53 percent male. Nearly three quarters (73.2%) had taken a potentially impairing class of medication and more than half (56.1%) had taken more than one such medication in the past 12 months. Knowledge of the potentially impairing effects of medication was relatively high for most items; however, participants underestimated the possibility of increased impairment from exceeding the prescribed dose and at commencing treatment. Participants' responses to the safety implications of taking drugs with the highest level of warning varied. Around two thirds (62.8%) indicated that they would consult a health practitioner for advice and around half would modify their driving in some way. However, one fifth (20.9%) would drive when the traffic was thought to be less heavy and over a third (37.7%) would modify their medication regime so that they could drive. The findings from the follow-up survey of a subsample taking target drugs at the time of the first interview were also of concern. Only just over half (51%) recalled seeing the warning label on their medications and, of this group, three quarters (78%) reported following the warning label advice. These findings indicated that there remains a large proportion of people who either did not notice or did not consider the warning when deciding whether to drive. There was a very high level of confidence in this group that they could

Worries about health threatening effects of potential health hazards of modern life (e.g. electric devices and pollution) represent a growing phenomenon in Western countries. Yet, little is known about the causes of this growing special case of affective risk perceptions termed Modern Health Worries (MHW). The purpose of this study is to examine a possible role of biased media reports in the formation of MHW. In two experiments, we investigated whether typical television reports affect MHW. In Study 1, 130 participants were randomly assigned to a film on idiopathic environmental intolerance (IEI) or a control film about cystic fibrosis. In Study 2, 82 participants were randomly assigned to either a film on the dangers of electromagnetic fields or a control condition. Increases in MHW after sensational media reports. In Study 1, only participants high on the personality trait of absorption revealed increased MHW after watching the IEI film. In Study 2, specifically worries about radiation were found to be elevated after watching the film on the dangers of electromagnetic fields compared to the control film. The results of both studies reveal a significant and specific influence of sensational short mass media reports on MHW. The influence of potential moderators such as absorption remains to be clarified.

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

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.

When utilized properly, social media offers several personal and professional benefits for the practicing surgeon, including peer networking, education, e-mentorship, marketing, recruitment, and patient outreach. However, unprofessional online behavior is common among surgeons, and this improper use of social media can be quite dangerous. This article reviews the dangers of social media and illustrates this with examples of unprofessional behavior and the associated consequences. It also provides recommendations for maintaining a professional and productive online persona. Surgeons must understand the various social media platforms and their target audience while upholding online professionalism at all times.

The media and suicide.

Sudak, Howard S; Sudak, Donna M

2005-01-01

The authors aim to inform readers of the theory that when newspapers, film, and television describe suicidal deaths, additional suicides may result by virtue of contagion or copy-cat effects; to review data that support and refute this theory; to present some promising and recommended ways to prevent copy-cat suicide; and to cite news-media examples of both particularly bad and good reporting. A review of the literature on media-related suicide was conducted, which included reviewing materials published in scientific journals and data published by the U.S. Public Health Service, Centers for Disease Control, and materials from private, not-for-profit agencies. Data support an increased number of suicides resulting from media accounts of suicide that romanticize or dramatize the description of suicidal deaths. Specific guidelines for the media that may be able to decrease these additional deaths have been devised. Psychiatrists should be familiar with the harm that may result from improper reporting of suicide in the media since they may be called upon by reporters or family members following the suicide of one of their patients or following the suicide of a newsworthy person. Following the media guidelines available may prevent such contagion effects from occurring.

To describe the use of social media during the antepartum and postpartum periods among first-time African American mothers and their support persons. A qualitative critical ethnographic research design within the contexts of family life course development theory and Black feminist theory. Participants were recruited from community-based, public health, and home visiting programs. A purposive sample was recruited, consisting of 14 pregnant African American women and eight support persons. Pregnant and postpartum African American women and their support persons were interviewed separately during the antepartum and postpartum periods. Data were analyzed thematically. Participants frequently used social media for education and social support and searched the Internet for perinatal and parenting information. Most participants reported using at least one mobile application during their pregnancies and after giving birth. Social media were typically accessed through smartphones and/or computers using different websites and applications. Although participants gleaned considerable information about infant development from these applications, they had difficulty finding and recalling information about infant feeding. Social media are an important vehicle to disseminate infant feeding information; however, they are not currently being used to full potential. Our findings suggest that future interventions geared toward African American mothers and their support persons should include social media approaches. The way individuals gather, receive, and interpret information is dynamic. The increasing popularity and use of social media platforms offers the opportunity to create more innovative, targeted mobile health interventions for infant feeding and breastfeeding promotion. © 2015 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

Attitudes towards requiring ignition interlocks for all driving while intoxicated offenders: findings from the 2010 HealthStyles Survey

2017-01-01

Ignition interlocks are effective in reducing recidivism among driving while intoxicated (DWI) offenders while installed on their vehicles. However, the devices are not widely used in the USA. This survey gauged public support for requiring ignition interlocks for all convicted DWI offenders including first-time offenders. 69% of respondents supported such a policy. Support was lowest (38%) among persons who reported drinking and driving in the past 30 days. Multivariate regression analysis indicated that support varied little by region, community size or most measured individual characteristics. Persons who did not drink and drive were 80% more likely to support the requirement than those who drink and drive. These findings suggest that laws requiring ignition interlocks for all convicted DWI offenders may face the most opposition in communities with high levels of drinking and driving. PMID:22773020

Effect of news coverage on the prevalence of drunk-driving behavior: evidence from a longitudinal study.

PubMed

Yanovitzky, Itzhak

2002-05-01

To examine the proposition that antidrunk driving messages in the news media contributed indirectly to the decline in drunk driving over the past two decades through their impact on related policy making processes. Time series regression techniques are applied to longitudinal data to examine the causal association between drivers' involvement in drunk-driving behavior, the volume of news coverage devoted to the drunk driving issue, and related policy making. Results show a significant contribution of news coverage to drunk-driving-related policy actions, which in turn are associated with a reduction in drunk driving among young and high-risk drivers. There was no evidence of a direct causal association between news coverage and change in drunk-driving behavior. News coverage of alcohol-related risky behaviors seems to provide a cost-effective way of reducing the prevalence of these practices by attracting institutional attention and prompting related environmental changes. Future interventions may benefit from actively seeking to influence news coverage of risky behaviors.

Teen Drivers’ Perceptions of Inattention and Cell Phone Use While Driving

2015-01-01

Objective Inattention to the roadway, including cell phone use while driving (cell phone calls, sending and reading texts, mobile app use and internet use), is a critical problem for teen drivers and increases risk for crashes. Effective behavioral interventions for teens are needed in order to decrease teen driver inattention related to cell phone use while driving. However, teens’ perceptions of mobile device use while driving is a necessary component for theoretically driven behavior change interventions. The purpose of this study was to describe teen drivers’ perceptions of cell phone use while driving in order to inform future interventions to reduce risky driving. Methods We conducted seven focus groups with a total of 30 teen drivers, ages 16–18, licensed for ≤1 year in Pennsylvania. The focus group interview guide and analysis were based on the Theory of Planned Behavior, identifying the attitudes, perceived behavioral control, and norms about inattention to the roadway. Directed descriptive content analysis was used to analyze the focus group interviews. All focus groups were coded by two research team members and discrepancies were reconciled. Themes were developed based on the data. Results Teens had a mean age of 17.39 (sd 0.52), mean length of licensure of 173.7 days (sd 109.2; range 4–364), were 50% male and predominately white (90%) and non-Hispanic (97%). From the focus group data, three major themes emerged; (1) Recognizing the danger but still engaging; (2) Considering context; and (3) Formulating safer behaviors that might reduce risk. In spite of recognizing hand-held cell phone use, texting and social media app use are dangerous and distracting while driving, teens and their peers often engage in these behaviors. Teens described how the context of the situation contributed to whether a teen would place or answer a call, write or respond to a text, or use a social media app. Teens identified ways in which they controlled their

Cataract is a leading cause of vision impairment in older adults, affecting almost half of those over age 75 years. Driving is a highly visual task and, as with other age groups, older adults rely on the personal automobile for travel. The purpose of this study was to examine the role of cataract in driving. Older adults (aged 55-85 years) with cataract (n = 279) and those without cataract (n = 105) who were legally licensed to drive were recruited from eye clinics to participate in a driving habits interview to assess driving status, exposure, difficulty, and "space" (the distance of driving excursions from home base). Crash data over the prior 5 years were procured from state records. Visual functional tests documented the severity of vision impairment. Compared to those without cataract, older drivers with cataract were approximately two times more likely to report reductions in days driven and number of destinations per week, driving slower than the general traffic flow, and preferring someone else to drive. Those with cataract were five times more likely to have received advice about limiting their driving. Those with cataract were four times more likely to report difficulty with challenging driving situations, and those reporting driving difficulty were two times more likely to reduce their driving exposure. Drivers with cataract were 2.5 times more likely to have a history of at-fault crash involvement in the prior 5 years (adjusted for miles driven/week and days driven/week). These associations remained even after adjustments for the confounding effects of advanced age, impaired general health, mental status deficit, or depression. Older drivers with cataract experience a restriction in their driving mobility and a decrease in their safety on the road. These findings serve as a baseline for our ongoing study evaluating whether improvements in vision following cataract surgery expand driving mobility and improve driver safety.

This paper highlights the development of tunnel magnetoresistive (TMR) sensors for magnetic tape recording applications. This has led to the introduction of a tape drives supporting a 15 TB native tape cartridge, currently the highest capacity available. Underscoring this development is the fact that the TMR sensors must run in continual contact with the tape media. This is contrasted with modern hard disk drive (hdd) sensors, which fly above the disk platters. Various challenges encountered in developing and deploying TMR are presented. In addition, advances to the write transducer are also discussed. Lastly, the authors show that future density scaling for tape recording, unlike that for hdd, is not facing limits imposed by photolithography or superparamagnetic physics, suggesting that cartridge capacity improvements of 4 to 6x will be achieved in the next 4 to 8 years.

A longitudinal study was designed with two objectives: first, to provide a wide cognitive, personality and social description of new drivers before they started to drive cars. Second, to examine the relationship between cognitive and other characteristics drivers had before obtaining their driving license and the number and type of accidents they were involved in during the first years as drivers. The longitudinal study started in 1997 and ended in 2002. The first assessment was made up of 241 individuals at the time they enrolled on the driving course. The follow-up evaluation in the year 2002 was carried out on 144 components of the initial sample after five years driving. Age, gender and education level were matched to represent the population of Spain. Participants were assessed with the Bender Test for visual-motor ability, the B101 Test for practical intelligence, the B19 Test for visual-motor bi-manual coordination, and the TKK-1108 for speed anticipation. Personality was also evaluated with the Rorschach test and the PSY (Psychological Assessment Questionnaire). Five years later, a new examination of all those variables was made as well as a structured interview with each participant in order to collect data relating to significant life events during that time, driving habits, opinions in relation to certain traffic rules and information on accidents, incidents and/or sanctions. Serious and/or minor accidents are concentrated on a few drivers. Accidentality is not related to gender or age, but educational level is related to serious accidents. The number of accidents (severe or minor ones) cannot be predicted if considered as a continuous variable, but it is possible if considered as a discrete variable. In this case two different cognitive profiles account for the number and type of accidents. The number and type of accidents during their first years of driving are related to the cognitive profiles of drivers assessed before they obtained their driving

Drawing on prior occupational choice research on entrepreneurs and self-employed business owners, we examined personality predictors of their occupational business success and work satisfaction. PARTICIPANTS AND PROCEDURES: A sample of 147 small business owners completed a web-based assessment of 14 work-related personality traits--adaptability, autonomy, competitiveness, dependability, emotional resilience, goal-setting, optimism, persistence, risk tolerance, self-promotion, networking, and tolerance for financial insecurity, work-based locus of control, and work drive--and three self-reported indices of business success--revenue growth, profit growth, and income growth--as well as multiple facets of individual satisfaction. Criterion variables included composite business success and overall satisfaction. Ten traits correlated with business success. The top four personality predictors of success--goal-setting, social networking, emotional resilience, and work drive--together accounted for 16% of the variance. Similarly, 12 of 14 personality traits were positively related to overall satisfaction. The top three personality predictors of satisfaction--optimism, work-based locus of control, and work drive--accounted for 29% of the variability in satisfaction. An expectancy analysis revealed that the percent of participants who reported at least a 20% increase in sales and profits the preceding year was 26% versus 54% for individual scoring in the lower and upper third of a personality composite measure. Results carry implications for future research, and have direct, practical applications for prospective and current entrepreneurs and self-employed owners of small businesses.

2011-06-20

Use of social media by doctors and medical students is common and growing. Although professional standards and codes of ethics that govern the behaviour of medical practitioners in Australia and New Zealand do not currently encompass social media, these codes need to evolve, because professional standards continue to apply in this setting. Inappropriate use of social media can result in harm to patients and the profession, including breaches of confidentiality, defamation of colleagues or employers, and violation of doctor-patient boundaries. The professional integrity of doctors and medical students can also be damaged through problematic interprofessional online relationships, and unintended exposure of personal information to the public, employers or universities. Doctors need to exercise extreme care in their use of social media to ensure they maintain professional standards.

To examine the relationship between disability-related humor and attitudes toward persons with disabilities in business students (i.e. "future employers"). Students watched one of two films designed to reduce negative attitudes toward persons with disabilities (one humorous in tone and the other serious in tone) or no film at all, and completed a measure of attitudes toward persons with disabilities. Results indicated that, after controlling for previous contact with persons with disabilities, age, and gender, students who watched the humorous film reported significantly more positive attitudes toward persons with disabilities. Disability humor may be an effective means of positively influencing attitudes toward persons with disabilities in future employers. [ • The acceptance and integration of persons with disabilities into society continues to be limited by negative attitudes.• Previous research has shown that employers with positive attitudes toward persons with disabilities maybe more likely to hire a person with a disability than employers with negative attitudes.• In this study, students who watched a humorous film reported significantly more positive attitudes toward persons with disabilities than students who watched a serious film or no film at all.• Consequently, it may be beneficial to embed disability humor into job-placement strategies in order to improve attitudes and positively influence hiring decisions.

2018-04-01

Exploring the scientific impact of online big-data has attracted much attention of researchers from different fields in recent years. Complex financial systems are typical open systems profoundly influenced by the external information. Based on the large-scale data in the public media and stock markets, we first define an information driving force, and analyze how it affects the complex financial system. The information driving force is observed to be asymmetric in the bull and bear market states. As an application, we then propose an agent-based model driven by the information driving force. Especially, all the key parameters are determined from the empirical analysis rather than from statistical fitting of the simulation results. With our model, both the stationary properties and non-stationary dynamic behaviors are simulated. Considering the mean-field effect of the external information, we also propose a few-body model to simulate the financial market in the laboratory.

To describe U.S. youth's access and exposure to the full array of media, as well as the social contexts in which media exposure occurs. A cross-sectional national random sample of 2065 adolescents aged 8 through 18 years, including oversamples of African-American and Hispanic youth, completed questionnaires about use of television, videotapes, movies, computers, video games, radio, compact discs, tape players, books, newspapers, and magazines. U.S. youngsters are immersed in media. Most households contain most media (computers and video game systems are the exception); the majority of youth have their own personal media. The average youth devotes 6 3/4 h to media; simultaneous use of multiple media increases exposure to 8 h of media messages daily. Overall, media exposure and exposure to individual media vary as a function of age, gender, race/ethnicity, and family socioeconomic level. Television remains the dominant medium. About one-half of the youth sampled uses a computer daily. A substantial proportion of children's and adolescents' media use occurs in the absence of parents. American youth devote more time to media than to any other waking activity, as much as one-third of each day. This demands increased parental attention and research into the effects of such extensive exposure.

The main objective of this study was to identify the prevalence of social media and Internet usage of orthopaedists and to determine its effects on patient-physician communication. Data were collected by e-mail from 321 orthopaedists who filled out the questionnaire. The questionnaire consists of a total 25 items pertaining to personal information, which social media tool they use, their overall views of and expectations from social media, the effects of social media on patient-physician relationship and communication. The rates of keeping in contact with patients and "often" helping patients to manage their treatments over social media increased with age ( p  < 0.05). It was found that the rate of helping patients to manage their treatments over social media was significantly higher in academicians compared to that in specialist physicians ( p  = 0.040). The rates of having a personal website and being a member of online physician platform and social-networking sites were higher in participants working in the private sector than participants working in the public sector ( p  = 0.001). It was found that the rate of finding it useful to be in contact with patients over social media was higher in physicians working in the private sector compared to that in those working in the public sector ( p  < 0.01). Social media tools and Internet are commonly used by orthopaedists to communicate with their patients. Even though there are beneficial effects in patient-physician relationship, effective standards and regulations should be developed to enable a safe communication and to resolve ethical and legal uncertainties.

The authors test the effects of news stories about mass shootings on public attitudes toward persons with serious mental illness and support for gun control policies. They also examine whether news coverage of proposals to prevent persons with serious mental illness from having guns exacerbates the public's negative attitudes toward this group. The authors conducted a survey-embedded randomized experiment using a national sample (N=1,797) from an online panel. Respondents were randomly assigned to groups instructed to read one of three news stories or to a no-exposure control group. The news stories described, respectively, a mass shooting by a person with serious mental illness, the same mass shooting and a proposal for gun restrictions for persons with serious mental illness, and the same mass shooting and a proposal to ban large-capacity magazines. Outcome measures included attitudes toward working with or living near a person with serious mental illness, perceived dangerousness of persons with serious mental illness, and support for gun restrictions for persons with serious mental illness and for a ban on large-capacity magazines. Compared with the control group, the story about a mass shooting heightened respondents' negative attitudes toward persons with serious mental illness and raised support for gun restrictions for this group and for a ban on large-capacity magazines. Including information about the gun restriction policy in a story about a mass shooting did not heighten negative attitudes toward persons with serious mental illness or raise support for the restrictions. The aftermath of mass shootings is often viewed as a window of opportunity to garner support for gun control policies, but it also exacerbates negative attitudes toward persons with serious mental illness.

The relationship of drive for muscularity to sociocultural factors, self-esteem, physical attributes gender role, and social comparison in middle school boys.

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.

Driving comfort, enjoyment and acceptance of automated driving - effects of drivers' age and driving style familiarity.

Automated driving has the potential to improve the safety and efficiency of future traffic and to extend elderly peoples' driving life, provided it is perceived as comfortable and joyful and is accepted by drivers. Driving comfort could be enhanced by familiar automated driving styles based on drivers' manual driving styles. In a two-stage driving simulator study, effects of driving automation and driving style familiarity on driving comfort, enjoyment and system acceptance were examined. Twenty younger and 20 older drivers performed a manual and four automated drives of different driving style familiarity. Acceptance, comfort and enjoyment were assessed after driving with standardised questionnaires, discomfort during driving via handset control. Automation increased both age groups' comfort, but decreased younger drivers' enjoyment. Younger drivers showed higher comfort, enjoyment and acceptance with familiar automated driving styles, whereas older drivers preferred unfamiliar, automated driving styles tending to be faster than their age-affected manual driving styles. Practitioner Summary: Automated driving needs to be comfortable and enjoyable to be accepted by drivers, which could be enhanced by driving style individualisation. This approach was evaluated in a two-stage driving simulator study for different age groups. Younger drivers preferred familiar driving styles, whereas older drivers preferred driving styles unaffected by age.

[Driving and dementia : An issue for general practice?!

With most forms of dementia, the risk of road traffic accidents increases with disease progression. Addressing the issue of fitness to drive at an early stage can help to reduce driving-related risks and simultaneously preserve mobility. General practitioners (GPs) are central contact persons for dementia patients and their relatives in medical and psychosocial matters, and also play a key role in addressing the issue of driving safety. Identification of relevant aspects of managing fitness to drive in dementia, as well as of support requirements for German general practice. Seven focus groups with dementia patients, family caregivers and GPs were conducted in order to define the different requirements for counselling in the general practice setting. The transcribed discussions were analysed by a multiprofessional research team using content analysis. For people with dementia, declining mobility and driving cessation is related to a loss of autonomy. Addressing fitness to drive in dementia is thus a subject of conflict and uncertainty for both family caregivers and GPs. The difficulties include the assessment of fitness to drive in the general practice setting, concerns about compromising the patient-physician relationship by raising the issue of driving fitness, as well as uncertainties about the GP's own role. GPs consider the involvement of caregivers to be important to successfully address the topic of driving safety and organise alternative transport. Support is required in the form of criteria defining the time point at which fitness to drive should be assessed, information on compensation possibilities and mobility alternatives. Resource-oriented and patient-centred development of management strategies for limited mobility is needed in general practice. Finding the correct balance between documentation, adequately informing the patient and establishing patient-centred strategies represents a challenge.

More than 200,000 individuals worldwide have received a cochlear implant (CI). Social media Websites may provide a paramedical community for those who possess or are interested in a CI. The utilization patterns of social media by the CI community, however, have not been thoroughly investigated. The purpose of this study was to investigate participation of the CI community in social media Websites. We conducted a systematic survey of online CI-related social media sources. Using standard search engines, the search terms cochlear implant, auditory implant, forum, and blog identified relevant social media platforms and Websites. Social media participation was quantified by indices of membership and posts. Social media sources included Facebook, Twitter, YouTube, blogs, and online forums. Each source was assigned one of six functional categories based on its description. No intervention was performed. We conducted all online searches in February 2014. Total counts of each CI-related social media source were summed, and descriptive statistics were calculated. More than 350 sources were identified, including 60 Facebook groups, 36 Facebook pages, 48 Twitter accounts, 121 YouTube videos, 13 forums, and 95 blogs. The most active online communities were Twitter accounts, which totaled 35,577 members, and Facebook groups, which totaled 17,971 members. CI users participated in Facebook groups primarily for general information/support (68%). Online forums were the next most active online communities by membership. The largest forum contained approximately 9,500 topics with roughly 127,000 posts. CI users primarily shared personal stories through blogs (92%), Twitter (71%), and YouTube (62%). The CI community engages in the use of a wide range of online social media sources. The CI community uses social media for support, advocacy, rehabilitation information, research endeavors, and sharing of personal experiences.

Large-scale strategies are needed to reduce overuse of antibiotics in US communities. To evaluate the impact of a mass media campaign-"Get Smart Colorado"-on public exposure to campaign, antibiotic use, and office visit rates. Nonrandomized controlled trial. Two metropolitan communities in Colorado, United States. The general public, managed care enrollees, and physicians residing in the mass media (2.2 million persons) and comparison (0.53 million persons) communities. : The campaign consisting of paid outdoor advertising, earned media and physician advocacy ran between November 2002 and February 2003. Antibiotics dispensed per 1000 persons or managed care enrollees, and the proportion of office visits receiving antibiotics measured during 10 to 12 months before and after the campaign. After the mass media campaign, there was a 3.8% net decrease in retail pharmacy antibiotic dispenses per 1000 persons (P = 0.30) and an 8.8% net decrease in managed care-associated antibiotic dispenses per 1000 members (P = 0.03) in the mass media community. Most of the decline occurred among pediatric members, and corresponded with a decline in pediatric office visit rates. There was no change in the office visit prescription rates among pediatric or adult managed care members, nor in visit rates for complications of acute respiratory tract infections. A low-cost mass media campaign was associated with a reduction in antibiotic use in the community, and seems to be mediated through decreases in office visits rates among children. The campaign seems to be cost-saving.

Addiction, Drinking Behavior, and Driving Under the Influence

Using a survey of drinkers (N=1,634), we evaluated alternative explanations of heavy and binge drinking, driving under the influence (DUI), DUI arrests, speeding citations, and chargeable accidents. Explanations included socializing, short-term decision-making, unrealistic optimism, risk preferring behavior, and addiction. Most consistent relationships were between substance use and alcohol addiction and dependent variables for (1) binge drinking and (2) DUI episodes. Respondent characteristics (age, marital and employment status, race) had important roles for DUI arrests. Drinker-drivers and those arrested for DUI are partially overlapping groups with implications for treatment and policies detecting and incapacitating persons from drinking and driving. PMID:24304171

Purpose To comprehensively investigate the types of driving errors and locations that are most problematic for older drivers with glaucoma compared to those without glaucoma using a standardized on-road assessment. Methods Participants included 75 drivers with glaucoma (mean = 73.2±6.0 years) with mild to moderate field loss (better-eye MD = -1.21 dB; worse-eye MD = -7.75 dB) and 70 age-matched controls without glaucoma (mean = 72.6 ± 5.0 years). On-road driving performance was assessed in a dual-brake vehicle by an occupational therapist using a standardized scoring system which assessed the types of driving errors and the locations where they were made and the number of critical errors that required an instructor intervention. Driving safety was rated on a 10-point scale. Self-reported driving ability and difficulties were recorded using the Driving Habits Questionnaire. Results Drivers with glaucoma were rated as significantly less safe, made more driving errors, and had almost double the rate of critical errors than those without glaucoma. Driving errors involved lane positioning and planning/approach, and were significantly more likely to occur at traffic lights and yield/give-way intersections. There were few between group differences in self-reported driving ability. Conclusions Older drivers with glaucoma with even mild to moderate field loss exhibit impairments in driving ability, particularly during complex driving situations that involve tactical problems with lane-position, planning ahead and observation. These results, together with the fact that these drivers self-report their driving to be relatively good, reinforce the need for evidence-based on-road assessments for evaluating driving fitness.

Interactive real-time media streaming with reliable communication

NASA Astrophysics Data System (ADS)

Pan, Xunyu; Free, Kevin M.

2014-02-01

Streaming media is a recent technique for delivering multimedia information from a source provider to an end- user over the Internet. The major advantage of this technique is that the media player can start playing a multimedia file even before the entire file is transmitted. Most streaming media applications are currently implemented based on the client-server architecture, where a server system hosts the media file and a client system connects to this server system to download the file. Although the client-server architecture is successful in many situations, it may not be ideal to rely on such a system to provide the streaming service as users may be required to register an account using personal information in order to use the service. This is troublesome if a user wishes to watch a movie simultaneously while interacting with a friend in another part of the world over the Internet. In this paper, we describe a new real-time media streaming application implemented on a peer-to-peer (P2P) architecture in order to overcome these challenges within a mobile environment. When using the peer-to-peer architecture, streaming media is shared directly between end-users, called peers, with minimal or no reliance on a dedicated server. Based on the proposed software pɛvμa (pronounced [revma]), named for the Greek word meaning stream, we can host a media file on any computer and directly stream it to a connected partner. To accomplish this, pɛvμa utilizes the Microsoft .NET Framework and Windows Presentation Framework, which are widely available on various types of windows-compatible personal computers and mobile devices. With specially designed multi-threaded algorithms, the application can stream HD video at speeds upwards of 20 Mbps using the User Datagram Protocol (UDP). Streaming and playback are handled using synchronized threads that communicate with one another once a connection is established. Alteration of playback, such as pausing playback or tracking to a

Alcohol-Impaired Driving and Perceived Risks of Legal Consequences.

PubMed

Sloan, Frank A; McCutchan, Sabrina A; Eldred, Lindsey M

2017-02-01

Driving while impaired (DWI) is a threat to public health. Codified legal sanctions are a widely implemented strategy to reduce DWI. However, it is unclear that sanctioning affects individual risk perceptions so as to deter alcohol-impaired driving. Using survey data collected from individual drivers, police, and defense attorneys specializing in DWI in 8 U.S. cities, we investigated whether risk perceptions about legal consequences for alcohol-impaired driving, both the risk of being stopped if driving while alcohol-impaired and receiving specific penalties following a DWI, deter alcohol-impaired driving. First, we analyzed how different drivers' risk perceptions about being pulled over and facing criminal sanctions related to their self-reported alcohol-impaired driving in the year following the interview at which risk perceptions were elicited. Second, using data from an experimental module in which individual's risk perceptions were randomly updated by the interview, we analyzed how each driver's beliefs about his or her own future alcohol-impaired driving responded to randomly generated increases in the apprehension probability and sanction magnitude. Higher probabilities as estimated by the individuals of being pulled over corresponded to less alcohol-impaired driving in both analyses. Conversely, there was no statistical relationship between perceptions of criminal sanctions for DWI and alcohol-impaired driving with 1 exception-a small significant negative relationship between duration of jail time following a DWI conviction and alcohol-impaired driving. Perceptions regarding the threat of being apprehended for alcohol-impaired driving were related to actual self-reported driving, while perceived sanctions following a DWI conviction for DWI generally were unrelated to either actual self-reported alcohol-impaired driving or the person's estimate of probability that he or she would drive while alcohol-impaired in the following year.

Social media platforms have revolutionized the way human beings communicate, yet there is little evidence describing how the plastic surgery community has adopted social media. In this article, the authors evaluate current trends in social media use by practicing plastic surgeons. An anonymous survey on the use of social media was distributed to members of the American Society of Plastic Surgeons. Prevalent patterns of social media implementation were elucidated. One-half of respondents were regular social media users. Reasons for using social media included the beliefs that incorporation of social media into medical practice is inevitable (56.7 percent), that they are an effective marketing tool (52.1 percent), and that they provide a forum for patient education (49 percent). Surgeons with a primarily aesthetic surgery practice were more likely to use social media. Most respondents (64.6 percent) stated that social media had no effect on their practice, whereas 33.8 percent reported a positive impact and 1.5 percent reported a negative impact. This study depicts current patterns of social media use by plastic surgeons, including motivations driving its implementation and impressions on its impact. Many feel that social media are an effective marketing tool that generates increased exposure and referrals. A small number of surgeons have experienced negative repercussions from social media involvement. Our study reveals the presence of a void. There is a definite interest among those surveyed in developing best practice standards and oversight to ensure ethical use of social media platforms throughout the plastic surgery community. Continuing discussion regarding these matters should be ongoing as our experience with social media in plastic surgery evolves.

Effects of trait anger, driving anger, and driving experience on dangerous driving behavior: A moderated mediation analysis.

To explore the effect of anger behind the wheel on driving behavior and accident involvement has been the subject of many studies. However, few studies have explored the interaction between anger and driving experience on dangerous driving behavior. This study is a moderated mediation analysis of the effect of trait anger, driving anger, and driving experience on driving behavior. A sample of 303 drivers was tested using the Trait Anger Scale (TAS), the Driving Anger Scale (DAS), and the Dula Dangerous Driving Index (DDDI). The results showed that trait anger and driving anger were positively correlated with dangerous driving behavior. Driving anger partially mediated the effect of trait anger on dangerous driving behavior. Driving experience moderated the relationship between trait anger and driving anger. It also moderated the effect of driving anger on dangerous driving behavior. These results suggest that drivers with more driving experience may be safer as they are not easily irritated during driving. © 2017 Wiley Periodicals, Inc.

Entry of terms reflective of extreme risky driving behaviors into the YouTube website yields millions of videos. The majority of the top 20 highly subscribed automotive YouTube websites are focused on high-performance vehicles, high speed, and often risky driving. Moreover, young men are the heaviest users of online video sharing sites, overall streaming more videos, and watching them longer than any other group. The purpose of this article is to review the literature on YouTube videos and risky driving. A systematic search was performed using the following specialized database sources-Scopus, PubMed, Web of Science, ERIC, and Google Scholar-for the years 2005-2015 for articles in the English language. Search words included "YouTube AND driving," "YouTube AND speeding," "YouTube AND racing." No published research was found on the content of risky driving videos or on the effects of these videos on viewers. This literature review presents the current state of our published knowledge on the topic, which includes a review of the effects of mass media on risky driving cognitions; attitudes and behavior; similarities and differences between mass and social media; information on the YouTube platform; psychological theories that could support YouTube's potential effects on driving behavior; and 2 examples of risky driving behaviors ("sidewalk skiing" and "ghost riding the whip") suggestive of varying levels of modeling behavior in subsequent YouTube videos. Every month about 1 billion individuals are reported to view YouTube videos (ebizMBA Guide 2015 ) and young men are the heaviest users, overall streaming more YouTube videos and watching them longer than women and other age groups (Nielsen 2011 ). This group is also the most dangerous group in traffic, engaging in more per capita violations and experiencing more per capita injuries and fatalities (e.g., Parker et al. 1995 ; Reason et al. 1990 ; Transport Canada 2015 ; World Health Organization 2015 ).

A concurrent mixed methods design was used to explore personal and workplace factors, informed by the Theory of Planned Behavior, that affect truck drivers' decision-making about distracted driving on the job. Qualitative data were collected via semi-structured interviews with experts in truck safety and distracted driving, and quantitative data were collected via online survey of truck drivers in the United States. Findings from the interviews illustrated how drivers perceived distractions and the importance of supervisors enforcing organizational distracted driving policies. Survey results found that behavioral intentions were most important in regards to texting and crash and near-crash outcomes, while perceived norms from management best described the correlation between dispatch device use and negative crash-related outcomes. By using a mixed methods design, rather than two separate studies, these findings revealed nuanced differences into the influence of supervisors on distracted driving. Copyright © 2015 Elsevier Ltd.

Kobayashi, Kazuyuki; Watanabe, Kajiro; Ohkubo, Tomoyuki; Kurihara, Yosuke

By the word “Personal vehicle”, we mean a simple and lightweight vehicle expected to emerge as personal ground transportation devices. The motorcycle, electric wheelchair, motor-powered bicycle, etc. are examples of the personal vehicle and have been developed as the useful for transportation for a personal use. Recently, a new types of intelligent personal vehicle called the Segway has been developed which is controlled and stabilized by using on-board intelligent multiple sensors. The demand for needs for such personal vehicles are increasing, 1) to enhance human mobility, 2) to support mobility for elderly person, 3) reduction of environmental burdens. Since rapidly growing personal vehicles' market, a number of accidents caused by human error is also increasing. The accidents are caused by it's drive ability. To enhance or support drive ability as well as to prevent accidents, intelligent assistance is necessary. One of most important elemental functions for personal vehicle is robust lane detection. In this paper, we develop a robust lane detection method for personal vehicle at outdoor environments. The proposed lane detection method employing a 360 degree omni directional camera and unique robust image processing algorithm. In order to detect lanes, combination of template matching technique and Hough transform are employed. The validity of proposed lane detection algorithm is confirmed by actual developed vehicle at various type of sunshined outdoor conditions.

The purpose of our study was to compare the cost-effectiveness of four strategies using components of 1% Or Less to promote population-based behavior change. 1% Or Less is a mass-media campaign that encourages switching from high-fat (whole or 2%) to low-fat (1% or skim) milk. Using a quasi-experimental design, campaigns were previously conducted in four West Virginia communities using different combinations of 1) paid advertising, 2) media relations, and 3) community-based educational activities. Telephone surveys and supermarket milk sales data were used to measure the campaigns' effectiveness. Using data from the previously completed studies, we analyzed the cost of each campaign. We then calculated the cost per person exposed to the campaign and cost per person who switched from high- to low-fat milk. The combination of paid advertising and media relations was the most cost-effective campaign, with a cost of 0.57 dollars per person to elicit a switch from high- to low-fat milk, and the combination of media relations and community-based educational activities was the least cost-effective campaign, with a cost of 11.85 dollars per person to elicit a switch. Population-based campaigns using a combination of paid advertising and media relations strategies can be a cost-effective way to promote a behavior change in a community.

To examine students' exposure to user-generated alcohol content on social media, and identify characteristics (i.e. demographics, personality traits, alcohol use, alcohol-related cognitions, and social media factors) associated with monthly or more frequent exposure. College/university students (N=11,236) in Bergen, Norway, completed a web-survey measuring exposure to alcohol on social media - both frequency and interpretations of alcohol content. The survey included questions regarding demographics, personality, alcohol-related cognitions, and general use of social media and alcohol. Binary logistic regressions were run to identify characteristics associated with monthly or more frequent exposure to alcohol-related posts on social media. A total of 96.7% had been exposed to alcohol-related posts, exposure to posts with a positive valence of alcohol were more frequently reported than exposure to content with a negative valence of alcohol. Reports of monthly or more frequent exposure to alcohol on social media were associated with a range of characteristics, among these younger age, being native Norwegian, lower extroversion and higher agreeableness and self-monitoring scores, higher alcohol use, stronger descriptive norms for alcohol use among online-friends, and more frequent logins to social media. Students' potential inflated alcohol norms (originating from social media) should be addressed. The results suggest that exposure may be determined by high alcohol use and membership in demographical groups associated with high alcohol use, an increased attentiveness towards others' behavior, and excessive social media use. Future studies investigating the relationship between alcohol exposure on social media and later alcohol use should control for such factors. Copyright © 2017 Elsevier Ltd. All rights reserved.

We also report that both personal income and household income are independently positively associated with license-holding but that (intuitively) the relationship of license holding with a young adult's own personal income is the much stronger of the two. On the basis of these findings, it can be concluded that a number of previously underappreciated factors appear to be linked with young British adults not acquiring a driving license.

Media multitasking behavior: concurrent television and computer usage.

PubMed

Brasel, S Adam; Gips, James

2011-09-01

Changes in the media landscape have made simultaneous usage of the computer and television increasingly commonplace, but little research has explored how individuals navigate this media multitasking environment. Prior work suggests that self-insight may be limited in media consumption and multitasking environments, reinforcing a rising need for direct observational research. A laboratory experiment recorded both younger and older individuals as they used a computer and television concurrently, multitasking across television and Internet content. Results show that individuals are attending primarily to the computer during media multitasking. Although gazes last longer on the computer when compared to the television, the overall distribution of gazes is strongly skewed toward very short gazes only a few seconds in duration. People switched between media at an extreme rate, averaging more than 4 switches per min and 120 switches over the 27.5-minute study exposure. Participants had little insight into their switching activity and recalled their switching behavior at an average of only 12 percent of their actual switching rate revealed in the objective data. Younger individuals switched more often than older individuals, but other individual differences such as stated multitasking preference and polychronicity had little effect on switching patterns or gaze duration. This overall pattern of results highlights the importance of exploring new media environments, such as the current drive toward media multitasking, and reinforces that self-monitoring, post hoc surveying, and lay theory may offer only limited insight into how individuals interact with media.

Antonson, Hans; Ahlström, Christer; Mårdh, Selina; Blomqvist, Göran; Wiklund, Mats

2014-01-01

According to the literature, landscape (panoramas, heritage objects e.g. landmarks) affects people in various ways. Data are primarily developed by asking people (interviews, photo sessions, focus groups) about their preferences, but to a lesser degree by measuring how the body reacts to such objects. Personal experience while driving a car through a landscape is even more rare. In this paper we study how different types of objects in the landscape affect drivers during their drive. A high-fidelity moving-base driving simulator was used to measure choice of speed and lateral position in combination with stress (heart rate measure) and eye tracking. The data were supplemented with questionnaires. Eighteen test drivers (8 men and 10 women) with a mean age of 37 were recruited. The test drivers were exposed to different new and old types of landscape objects such as 19th century church, wind turbine, 17th century milestone and bus stop, placed at different distances from the road driven. The findings are in some respect contradictory, but it was concluded that that 33% of the test drivers felt stressed during the drive. All test drivers said that they had felt calm at times during the drive but the reason for this was only to a minor degree connected with old and modern objects. The open landscape was experienced as conducive to acceleration. Most objects were, to a small degree, experienced (subjective data) as having a speed-reducing effect, much in line with the simulator data (objective data). Objects close to the road affected the drivers' choice of' lateral position. No significant differences could be observed concerning the test drivers' gaze between old or modern objects, but a significant difference was observed between the test drivers' gaze between road stretches with faraway objects and stretches without objects. No meaningful, significant differences were found for the drivers' stress levels as measured by heart rate. Copyright © 2013 Elsevier Ltd. All

To understand the attitudes and practices of urologists regarding social media use. Social media services have become ubiquitous, but their role in the context of medical practice is underappreciated. A survey was sent to all active members of the Canadian Urological Association by e-mail and surface mail. Likert scales were used to assess engagement in social media, as well as attitudes toward physician responsibilities, privacy concerns and patient interaction online. Of 504 surveys delivered, 229 were completed (45.4%). Urologists reported frequent or daily personal and professional social media use in 26% and 8% of cases, respectively. There were no differences between paper (n = 103) or online (n = 126; P > 0.05) submissions. Among frequent social media users, YouTube (86%), Facebook (76%), and Twitter (41%) were most commonly used; 12% post content or links frequently to these sites. The most common perceived roles of social media in health care were for inter-professional communication (67%) or as a simple information repository (59%); online patient interaction was endorsed by 14% of urologists. Fewer than 19% had read published guidelines for online patient interaction, and ≤64% were unaware of their existence. In all, 94.6% agreed that physicians need to exercise caution personal social media posting, although 57% felt that medical regulatory bodies should 'stay out of [their] personal social media activities', especially those in practice <10 years (P = 0.001). In all, 56% agreed that social media integration in medical practice will be 'impossible' due to privacy and boundary issues; 73% felt that online interaction with patients would become unavoidable in the future, especially those in practice >20 years (P = 0.02). Practicing urologists engage infrequently in social media activities, and are almost universal in avoiding social media for professional use. Most feel that social media is best kept to exchanges between colleagues. Emerging data

[Effects of message and personal involvement on risk perception and acceptance].

PubMed

Masuchi, A; Takigawa, T

1999-10-01

The present study analyzed people's risk perception regarding driving a car with studded or non-studded winter tires. Subjects were 252 residents of Sapporo, where a recent municipal ordinance prohibited studded tires, allowing only non-studded ones. Questionnaire data were examined concerning (1) the relationship between risk perception and its acceptance, (2) the effect of an inserted message, which was either positive or negative about the use of non-studded tires, and (3) the role of personal involvement, assessed with Personal Involvement Inventory (Zaichkowsky, 1985), regarding winter driving. Results were as follows: (1) The use of non-studded tires was favorably judged because of social benefit, but subjects hesitated to choose them because of a higher perceived possibility of an accident. (2) The inserted message had significant effects on benefit evaluation and perceived accident possibility. The effects were weaker for drivers who had experienced driving a car with studded tires. And (3) personal involvement had a weak correlation with risk judgements of the present study.

The present study examined the types of situations that caused Chinese professional and non-professional drivers to become angry and investigated the differences in driving-elicited anger, considering the influences of type A behavior pattern and trait anger between the two groups. The 20-item revised Driving Anger Scale (DAS) was used to assess a sample of 232 drivers (57% professional, 43% non-professional). The non-professional drivers reported significantly higher levels of anger than the professional drivers on the overall Driving Anger Scale (DAS) and the traffic obstructions and discourtesy subscales. In both groups, the preferred driving speeds were positively related to driving anger. Furthermore, drivers with a type A personality exhibited higher overall driving anger scores and higher anger scores in response to traffic obstructions and slow driving than drivers with a type B personality. Trait anger was significantly related to driving anger in both groups. In the non-professional group, type A behavior patterns (TABPs) and time hurry (TH) were positively correlated with anger evoked by slow driving. In the professional group, TABPs, TH and competitive hostility (CH) were positively related to driving anger, and the TABPs exerted an indirect effect on driving anger by mediating the influence of trait anger. Overall, these findings provide a theoretical basis for implementing targeted interventions for driving anger in both professional and non-professional drivers. PMID:29253004

2012-01-01

Many U.S. states rely on older adults to self-regulate their driving and determine when driving is no longer a safe option. However, the relationship of older adults’ self-rated driving in terms of actual driving competency outcomes is unclear. The current study investigates self-rated driving in terms of (1) systematic differences between older adults with high (good/excellent) versus low (poor/fair/average) self-ratings, and (2) the predictive nature of self-rated driving to adverse driving outcomes in older drivers (n=350; mean age 73.9, SD=5.25, range 65–91). Adverse driving outcomes included self-reported incidences of (1) being pulled over by the police, (2) receiving a citation, (3) receiving a recommendation to cease or limit driving, (4) crashes, and (5) state-reported crashes. Results found that older drivers with low self-ratings reported more medical conditions, less driving frequency, and had been given more suggestions to stop/limit their driving; there were no other significant differences between low and high self-raters. Logistic regression revealed older drivers were more likely to have a state-reported crash and receive a suggestion to stop or limit driving. Men were more likely to report all adverse driving outcomes except for receiving a suggestion to stop or limit driving. Regarding self-rated driving, older adults with high ratings were 66% less likely (OR=0.34, 95% CI=0.14–0.85) to have received suggestions to limit or stop driving after accounting for demographics, health and driving frequency. Self-ratings were not predictive of other driving outcomes (being pulled over by the police, receiving a citation, self-reported crashes, or state-reported crashes, ps>.05). Most older drivers (85.14%) rated themselves as either good or excellent drivers regardless of their actual previous citation or crash rates. Self-rated driving is likely not related to actual driving proficiency as indicated by previous crash involvement in older adults

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

As personalized medicine becomes more applicable to oncologic practice, image-guided biopsies will be integral for enabling predictive and pharmacodynamic molecular pathology. Interventional radiology has a key role in defining patient-specific management. Advances in diagnostic techniques, genomics, and proteomics enable a window into subcellular mechanisms driving hyperproliferation, metastatic capabilities, and tumor angiogenesis. A new era of personalized medicine has evolved whereby clinical decisions are adjusted according to a patient’s molecular profile. Several mutations and key markers already have been introduced into standard oncologic practice. A broader understanding of personalized oncology will help interventionalists play a greater role in therapy selection and discovery. PMID:23885909

Driven by the increasing channel count of neural probes, there is much effort being directed to creating increasingly scalable electrophysiology data acquisition (DAQ) systems. However, all such systems still rely on personal computers for data storage, and thus are limited by the bandwidth and cost of the computers, especially as the scale of recording increases. Here we present a novel architecture in which a digital processor receives data from an analog-to-digital converter, and writes that data directly to hard drives, without the need for a personal computer to serve as an intermediary in the DAQ process. This minimalist architecture may support exceptionally high data throughput, without incurring costs to support unnecessary hardware and overhead associated with personal computers, thus facilitating scaling of electrophysiological recording in the future.
