Purpose Over 20% of young adults in New Mexico currently smoke. We evaluated cigarette smoking prevalence of young adult bar patrons during an anti-tobacco Social Branding intervention. Methods The Social Branding intervention used a smoke-free brand, “HAVOC,” to compete with tobacco marketing within the “Partier” young adult peer crowd. A series of cross-sectional surveys were collected from adults aged 18–26 in bars and nightclubs in Albuquerque, New Mexico, from 2009 to 2013 using randomized time-location sampling. Multivariable multinomial regression using full information maximum likelihood estimation to account for missing data evaluated differences in daily and nondaily smoking during the intervention, controlling for demographics, other risk behaviors, and tobacco-related attitudes. Results Data were collected from 1,069 individuals at Time 1, and 720, 1,142, and 1,149 participants at Times 2, 3, and 4, respectively. Current smoking rates decreased from 47.5% at Time 1 to 37.5% at Time 4 (p < .001). Among Partiers, the odds of daily smoking decreased significantly, but nondaily smoking was unchanged. Partiers that recalled, liked, and understood the smoke-free message of HAVOC had lower odds of nondaily (odds ratio: .48, 95% CI: .31–.75) and daily (odds ratio: .31,95% CI: .14–.68) smoking than those who did not recall HAVOC. HAVOC recall was associated with attitudes that were also associated with smoking behavior. Conclusions The significant decrease in daily smoking among young adult Partiers in New Mexico was associated with HAVOC recall and understanding. Social Branding interventions efficiently target and may decrease tobacco use among young adult bar patrons. PMID:27265423

Social benefits likely play a role in young adult tobacco use. The Social Prioritization Index (SPI) was developed to measure the degree to which young adults place a great importance on their social lives. We examined the usefulness of this measure as a potential predictor of tobacco use controlling for demographics and tobacco-related attitudes. Young adults completed cross-sectional surveys between 2012 and 2014 in bars in seven U.S. cities (N = 5,503). The SPI is a 13-item scale that includes personality items and information on how frequently participants attend bars and how late they stay out. Three step-by-step multinomial regression models were run using the SPI as a predictor of smoking status (nondaily and daily smoking vs. nonsmoking): (1) SPI as the sole predictor, (2) SPI and demographics, and (3) SPI, demographics, and tobacco-related attitude variables. Next, we conducted an exploratory factor analysis to examine if the number of items in SPI could be reduced and retain its strong relationship with smoking. Higher scores on the SPI were related to an increased probability of being a Nondaily Smoker (odds ratio = 1.09, 95% confidence interval [1.04, 1.14], p < .001) or Daily Smoker (odds ratio = 1.14, 95% confidence interval [1.07, 1.22], p < .0001) compared to a Nonsmoker, controlling for demographics and other tobacco-related attitudes. The SPI and reduced SPI were independently related to young adult tobacco use. The measure’s brevity, ease of use, and strong association with tobacco use may make it useful to tobacco and other prevention researchers. PMID:26706863

Rydon, P; Stockwell, T; Lang, E; Beel, A

1996-06-01

Compliance of bar staff with the Western Australian liquor law prohibiting service to drunk patrons was assessed through the deployment of actors trained to behave in a drunken manner. The serving practices of 23 licensed premises (19 hotels and four nightclubs) were examined. During 120 visits to hotel and nightclub bars, more than 350 drink orders were placed by pairs of pseudo-drunk actors who ordered up to three drinks each on each visit. On placing these drink orders, pseudo-drunks were refused service by bar staff on only 12 occasions. The rate of refusal of service across all premises was 10 per cent of visits. Partial interventions by servers, such as offering food or low-alcohol or nonalcoholic drinks, occurred in only four instances of the 120 visits. Qualitative observations and results obtained from a separate study examining a subsample of the servers who trained in responsible service of alcohol are discussed.

2015-01-01

Objectives. We examined loose cigarette (loosie) purchasing behavior among young adult (aged 18–26 years) smokers at bars in New York City and factors associated with purchase and use. Methods. Between June and December 2013, we conducted cross-sectional surveys (n = 1916) in randomly selected bars and nightclubs. Using multivariable logistic regression models, we examined associations of loose cigarette purchasing and use with smoking frequency, price, social norms, cessation behaviors, and demographics. Results. Forty-five percent (n = 621) of nondaily smokers and 57% (n = 133) of daily smokers had ever purchased a loosie; 15% of nondaily smokers and 4% of daily smokers reported that their last cigarette was a loosie. Nondaily smokers who never smoked daily were more likely than were daily smokers to have last smoked a loosie (odds ratio = 7.27; 95% confidence interval = 2.35, 22.48). Quitting behaviors and perceived approval of smoking were associated with ever purchasing and recently smoking loosies. Conclusions. Loosie purchase and use is common among young adults, especially nondaily smokers. Smoking patterns and attitudes should be considered to reduce loose cigarette purchasing among young adults in New York City. PMID:25880951

Objectives. We evaluated a Social Branding antitobacco intervention for “hipster” young adults that was implemented between 2008 and 2011 in San Diego, California. Methods. We conducted repeated cross-sectional surveys of random samples of young adults going to bars at baseline and over a 3-year follow-up. We used multinomial logistic regression to evaluate changes in daily smoking, nondaily smoking, and binge drinking, controlling for demographic characteristics, alcohol use, advertising receptivity, trend sensitivity, and tobacco-related attitudes. Results. During the intervention, current (past 30 day) smoking decreased from 57% (baseline) to 48% (at follow-up 3; P = .002), and daily smoking decreased from 22% to 15% (P < .001). There were significant interactions between hipster affiliation and alcohol use on smoking. Among hipster binge drinkers, the odds of daily smoking (odds ratio [OR] = 0.44; 95% confidence interval [CI] = 0.30, 0.63) and nondaily smoking (OR = 0.57; 95% CI = 0.42, 0.77) decreased significantly at follow-up 3. Binge drinking also decreased significantly at follow-up 3 (OR = 0.64; 95% CI = 0.53, 0.78). Conclusions. Social Branding campaigns are a promising strategy to decrease smoking in young adult bar patrons. PMID:24524502

Background Despite efforts to reduce exposure to secondhand smoke (SHS), only 5% of the world's population enjoy smoke-free restaurants and bars. Methods Lifetime excess risk (LER) of cancer death, ischaemic heart disease (IHD) death and asthma initiation among non-smoking restaurant and bar servers and patrons in Minnesota and the US were estimated using weighted field measurements of SHS constituents in Minnesota, existing data on tobacco use and multiple dose-response models. Results A continuous approach estimated a LER of lung cancer death (LCD) of 18×10−6(95% CI 13 to 23×10−6) for patrons visiting only designated non-smoking sections, 80×10−6(95% CI 66 to 95×10−6) for patrons visiting only smoking venues/sections and 802×10−6(95% CI 658 to 936×10−6) for servers in smoking-permitted venues. An attributable-risk (exposed/non-exposed) approach estimated a similar LER of LCD, a LER of IHD death about 10−2 for non-smokers with average SHS exposure from all sources and a LER of asthma initiation about 5% for servers with SHS exposure at work only. These risks correspond to 214 LCDs and 3001 IHD deaths among the general non-smoking population and 1420 new asthma cases among non-smoking servers in the US each year due to SHS exposure in restaurants and bars alone. Conclusions Health risks for patrons and servers from SHS exposure in restaurants and bars alone are well above the acceptable level. Restaurants and bars should be a priority for governments’ effort to create smoke-free environments and should not be exempt from smoking bans. PMID:23407112

We evaluated the impact on alcohol intake and blood alcohol concentration (BAC) of a multi-level structural intervention to increase the availability of free water, coupled with messaging on pacing alcohol intake and normative feedback of blood alcohol concentration in a convenience sample of gay bars in San Francisco. Participants (n = 1,293) were recruited among exiting patrons of four gay bars (two intervention bars and two control bars). Participants were surveyed on alcohol intake and BAC was measured by breathalyzer. Prior to the intervention there were no significant differences in baseline alcohol measures between intervention and control bars. Post-intervention there were significant differences on objective and subjective measures of alcohol consumption: 30% of intervention bar participants had BAC% levels over the legal driving limit (0.08%) compared to 43% of control bar participants, p < 0.0001 and 78% of intervention bar participants were above the AUDIT-C cut-off for hazardous drinking compared to 87% in control bars, p < 0.001.

Nkosi, Sebenzile; Rich, Eileen P; Morojele, Neo K

2014-11-01

We examined the relative importance of alcohol consumption and sexual relationship power (SRP) in predicting unprotected sex among 406 bar patrons in North West province, South Africa. We assessed participants' demographic characteristics, alcohol consumption, SRP, and number of unprotected sexual episodes in the past 6 months. In correlational analyses, alcohol consumption was significantly associated with frequency of unprotected sex for both males and females. SRP was significantly associated with frequency of unprotected sex for males and marginally associated for females. In multivariate regression analyses, alcohol consumption was significantly associated with frequency of unprotected sex for both males and females. SRP's association was marginally significant for females and not significant for males. Alcohol consumption is more strongly associated with unprotected sex than is SRP among bar patrons. Combination HIV prevention approaches to curb problem drinking and increase condom accessibility, and regular and effective use are needed in tavern settings. SRP needs further examination among tavern populations.

Social Organization in Bars: Implications for Tobacco Control Policy

2011-01-01

This paper considers social roles and relationships of the patrons, staff and owners of bars as critical factors determining adherence to public health policies, and specifically California’s smokefree workplace law. Specific elements of social organization in bars affecting health policy include the community within which the bar is set, the unique identity the bar creates, the bar staff and patrons who enact this identity, and their bar society. These elements were found to contribute to the development of power relations within the bar and solidarity against the outside world, resulting in either resistance to or compliance with smokefree workplace policy.

Bad nights or bad bars? Multi-level analysis of environmental predictors of aggression in late-night large-capacity bars and clubs.

Graham, Kathryn; Bernards, Sharon; Osgood, D Wayne; Wells, Samantha

2006-11-01

To clarify environmental predictors of bar-room aggression by differentiating relationships due to nightly variations versus across bar variations, frequency versus severity of aggression and patron versus staff aggression. Male-female pairs of researcher-observers conducted 1334 observations in 118 large capacity (> 300) bars and clubs in Toronto, Canada. Observers independently rated aspects of the environment (e.g. crowding) at every visit and wrote detailed narratives of each incident of aggression that occurred. Measures of severity of aggression for the visit were calculated by aggregating ratings for each person in aggressive incidents. Although bivariate analyses confirmed the significance of most environmental predictors of aggression identified in previous research, multivariate analyses identified the following key visit-level predictors (controlling for bar-level relationships): rowdiness/permissive environment and people hanging around after closing predicted both frequency and severity of aggression; sexual activity, contact and competition and people with two or more drinks at closing predicted frequency but not severity of aggression; lack of staff monitoring predicted more severe patron aggression, while having more and better coordinated staff predicted more severe staff aggression. Intoxication of patrons was significantly associated with more frequent and severe patron aggression at the bar level (but not at the visit level) in the multivariate analyses and negatively associated with severity of staff aggression at the visit level. The results demonstrate clearly the importance of the immediate environment (not just the type of bar or characteristics of usual patrons) and the importance of specific environmental factors, including staff behaviour, in predicting both frequency and severity of aggression.

Patronizing the young: forms and evaluations.

PubMed

Giles, H; Williams, A

1994-01-01

Exploratory work indicated that Californian undergraduates were frequently, and irritatingly, patronized by older adults in a variety of ways. In a follow-up, using multidimensional scaling procedures, three distinct clusters representing young adults' own conceptions of patronizing speech emerged ("non-listening," "disapproving," and "parental"). In the main study, young adults were provided with a single vignette of a short conversation between an older and younger person. Eight versions of this vignette were devised independently varying elder's age (40- vs. 70-years) and speech style (neutral vs. non-listening vs. disapproving vs. parental). Participants were required to evaluate both vignette-targets. As expected, the patronizing elders were negatively perceived. An evaluative hierarchy differentiated between the three patronizing forms, and in ways that differed depending on the nature of the judgmental task. Content analyses of open-ended data also revealed interesting differences in interpretive responses to the various vignette conditions.

Chaney, Beth H; Vail-Smith, Karen; Martin, Ryan J; Cremeens-Matthews, Jennifer

2016-09-01

The current study seeks to: 1) assess the relationship between alcohol consumption and intentions to engage in unprotected sex in an uncontrolled environment, and 2) to identify if covariates (race, age, sex, breath alcohol content (BrAC), intentions to engage in sex, hazardous drinking rates) are significant predictors of condom possession during time of uncontrolled alcohol consumption. Data were collected from 917 bar patrons to assess alcohol use using the Alcohol Use Disorders Identification Test (AUDIT-C), BrAC levels, intentions to engage in risky sex, and condom possession. Correlational analysis and hierarchical binary logistic regression was conducted using SPSS. Correlational analyses indicated a negative relationship between AUDIT-C scores (r=-0.115, p=0.001), BrAC (r=-0.08, p=0.015), and intentions to use a condom. Over 70% of participants intended to use a condom if they engaged in sex; however, only 28.4% had a condom to use. The regression analysis indicated the predictive model (χ(2)=114.5, df=8, p<0.001) was statistically significant, and correctly classified 72.9% of those in possession of a condom. Alcohol consumption was associated with intentions to have unprotected sex; however, intentions to engage in protected sex and condom possession were higher for males and those with higher BrAC levels.

The authors describe the epidemiology of risk behavior associated with poly-drug use in a college bar district of a large campus community. A total of 469 bar patrons participated in the study. The authors used self-report data and biological measures collected from patrons outside bars in July and August of 2007. The mean breath alcohol concentration of the exiting patrons was 0.09. Illicit and prescription drug use on the nights of data collection and in the recent past were significant features of the profile of patron risk behavior. About one-quarter of the patrons using only alcohol reported an intention to drive a vehicle within 60 minutes of leaving an establishment, compared with almost one-half of those using both alcohol and marijuana. A substantial amount of high-risk behavior was generated from the bar district on 4 typical nights. College bar districts should be a priority focus for prevention efforts.

To identify antecedents of risk behavior events in college bar patrons. In this nighttime field study, self-report data and alcohol intoxication readings were collected from patrons immediately upon exiting bars (n = 618). Multilevel structural equation modeling revealed positive associations between age of drinking onset and both alcohol use intensity in the past year and recent bar-going frequency. In turn, alcohol use intensity in the past year was positively associated with bar-going frequency and intoxication at bar exit. An association between drinking onset and bar-going frequency was mediated by alcohol use intensity in the past year. Discernable paths from age of drinking onset to monthly bar-going frequency and intoxication level after leaving a bar can be identified. The results highlight the critical role of drinking onset in development of college student alcohol abuse. Research is needed to determine whether college bars are environmental pathogens mediating between genetic risk factors and patron risk behavior.

Correlates of Persistent Smoking in Bars Subject to Smokefree Workplace Policy

Moore, Roland S.; Lee, Juliet P.; Martin, Scott E.; Todd, Michael; Chu, Bong Chul

2009-01-01

This study’s goal was to characterize physical and social environments of stand-alone bars associated with indoor smoking despite California’s smokefree workplace law. In a random sample of 121 stand-alone bars in San Francisco, trained observers collected data on patrons, staff, neighborhood, indoor settings and smoking behaviors. Using bivariate (chi-square) and hierarchical linear modeling analyses, we identified four correlates of patrons’ indoor smoking: 1) bars serving predominantly Asian or Irish patrons, 2) ashtrays, 3) bartender smoking, and 4) female bartenders. Public health officials charged with enforcement of smokefree bar policies may need to attend to social practices within bars, and heighten perceptions of consistent enforcement of smokefree workplace laws.

2003-01-01

Objective: To assess long term compliance with the California Smoke-Free Workplace Law in Los Angeles County freestanding bars and bar/restaurants. Design: Population based annual site inspection survey of a random sample of Los Angeles County freestanding bars and bar/restaurants was conducted from 1998 to 2002. Main outcome measures: The primary outcomes of interest were patron and employee smoking. The secondary outcomes of interest were the presence of ashtrays and designated outdoor smoking areas. Results: Significant increases in patron non-smoking compliance were found for freestanding bars (45.7% to 75.8%, p < 0.0001) and bar/restaurants (92.2% to 98.5%, p < 0.0001) between 1998 and 2002. Increases in employee non-smoking compliance were found for freestanding bars (86.2% to 94.7%, p < 0.0003) and bar/restaurants (96.5% to 99.2%, p < 0.005). Conclusions: This study provides clear evidence that the California Smoke-Free Workplace Law has been effective at reducing patron and employee smoking in Los Angeles County bars and restaurants. Recommendations include educational campaigns targeted to freestanding bar owners and staff to counter perceptions of lost revenue, more rigorous enforcement, and more severe penalties for repeat violators such as alcohol licence revocation. Policymakers can enact smoke-free restaurant and bar policies to protect employees and patrons from secondhand smoke, confident that these laws can be successfully implemented. PMID:12958386

Young adults: vulnerable new targets of tobacco marketing.

PubMed

Biener, Lois; Albers, Alison B

2004-02-01

We examined young adult smoking patterns and receptivity to cigarette advertising to assess vulnerability to tobacco marketing strategies. We obtained data from a telephone survey of 12,072 Massachusetts adults. Smokers aged 18 to 30 years were more likely than older adults to smoke only occasionally and to consume fewer than 10 cigarettes per day. They also were more receptive to cigarette marketing and were more likely to be frequent patrons of bars and clubs. Many young adult smokers are in the initiation phase of smoking and are likely to undergo a transition to either nonsmoking or heavier smoking. If unimpeded by regulation, tobacco promotion in bars and clubs is likely to lead to increased adult smoking prevalence.

Objectives. We examined patron responses to a California smoke-free bar law. Methods. Three telephone surveys measured attitudes and behavior changes after implementation of the law. Results. Approval of the law rose from 59.8% to 73.2% (odds ratio [OR] = 1.95; 95% confidence interval [CI] = 1.58, 2.40). Self-reported noncompliance decreased from 24.6% to 14.0% (OR = 0.50; 95% CI = 0.30, 0.85). Likelihood of visiting a bar or of not changing bar patronage after the law was implemented increased from 86% to 91% (OR = 1.76; 95% CI = 1.29, 2.40). Conclusions. California bar patrons increasingly support and comply with the smoke-free bar law. PMID:12660206

Intoxication in and around licensed premises continues to be common, despite widespread training in the responsible service of alcohol and laws prohibiting service to intoxicated individuals. However, research suggests that training and the existence of laws are unlikely to have an impact on intoxication without enforcement, and evidence from a number of countries indicates that laws prohibiting service to intoxicated individuals are rarely enforced. Enforcement is currently hampered by the lack of a standardized validated measure for defining intoxication clearly, a systematic approach to enforcement and the political will to address intoxication. We argue that adoption of key principles from successful interventions to prevent driving while intoxicated could be used to develop a model of consistent and sustainable enforcement. These principles include: applying validated and widely accepted criteria for defining when a person is 'intoxicated'; adopting a structure of enforceable consequences for violations; implementing procedures of unbiased enforcement; using publicity to ensure that there is a perceived high risk of being caught and punished; and developing the political will to support ongoing enforcement. Research can play a critical role in this process by: developing and validating criteria for defining intoxication based on observable behaviour; documenting the harms arising from intoxication, including risk curves associated with different levels of intoxication; estimating the policing, medical and social costs from intoxicated bar patrons; and conducting studies of the cost-effectiveness of different interventions to reduce intoxication. © 2013 Society for the Study of Addiction.

Electronic music and dance events in nightclubs attract patrons with heavy alcohol/drug use. Public health concerns are raised from risks related to these behaviors. Practices associated with increased risk in these club settings need to be identified. The relationship between club management practices and biological measures of patrons' alcohol/drug use is examined. Observational data from 25 events across six urban clubs were integrated with survey data (N = 738 patrons, 42.8% female) from patrons exiting these events, 2010-2012. Five indicators of club management practices were examined using mixed model regressions: club security, bar crowding, safety signs, serving intoxicated patrons, and isolation. Analyses revealed that serving intoxicated patrons and safety signs were related to substance use. Specifically, serving intoxicated patrons was related to heavy alcohol and drug use at exit, while safety signs were marginally related to less exit drug use. CONCLUSIONS/IMPORTANCE: Findings indicate observable measures in nightclubs provide important indicators for alcohol/drug use, suggesting practices to target. Study strengths include the use of biological measures of substance use on a relatively large scale. Limitations and future directions are discussed.

Changes in smoking-related norms in bars resulting from California's Smoke-Free Workplace Act.

2012-01-01

California's Smoke-Free Workplace Act--CA Labor Code Sec. 6404.5(a)--was extended to bars in 1998. This article analyzes changes in normative beliefs and behaviors related to bar smoking in the decade following the adoption of the Act. In a series of studies evaluating the smoke-free workplace law in bars, researchers conducted extensive observations and interviews with bar staff and patrons, health officials, and law enforcement personnel in three California counties. Smoking outside became a normal pause in the social environment and created a new type of bar socializing for outside smokers. Although some bar owners and staff reported initially resenting the responsibility to uphold the law, once norms regarding cigarettes and smoking began changing, bar workers experienced less conflict in upholding the law. Non-smoking behavior within bars also became the normative behavior for bar patrons. California's Smoke-Free Workplace Act has both reflected and encouraged normative beliefs and behaviors related to smoking in bars. The findings indicate that such shifts are possible even in contexts where smoking behaviors and attitudes supporting smoking were deeply entrenched. Recommendations include attending to the synergistic effect of education and policy in effective tobacco control programs.

[Purpose] The purpose of this study was to assess the effects of flexi-bar exercises and non-flexi-bar exercises on trunk muscle activity in different postures in healthy adults. [Subjects] Twenty healthy right-hand dominant adults (10 males and 10 females) were selected for this study. None of the participants had experienced any orthopedic problems in the spine or in the upper and lower extremities in the previous six months. [Methods] The subjects were instructed to adopt three exercise postures: posture 1, quadruped; posture 2, side-bridge; and posture 3, standing. Surface electromyography of selected trunk muscles was normalized to maximum voluntary isometric contraction. [Results] The external oblique, internal oblique, and erector spinae muscle activity showed significant differences between flexi-bar exercises and non-flexi-bar exercises. [Conclusion] The results of this study suggest that flexi-bar exercises are useful in the activation of trunk muscles.

The purpose of this paper is to explore the characteristics of bars where drug use was observed compared to those where no drug use was observed. The study was done through a combination of qualitative and quantitative techniques gleaned through observations and interviews. Among the most important of indicators were the type of activity (particularly dancing) and the level of rowdiness evident in the bars. In addition drug use bars had higher levels of other types of rule-breaking. Patron characteristics (more men) and behavioral patterns (more sexual risk-taking) also distinguished these bars.

This article describes the tobacco industry's use of bars and nightclubs to encourage smoking among young adults. Previously secret tobacco industry marketing documents were analyzed. Tobacco industry bar and nightclub promotions in the 1980s and 1990s included aggressive advertising, tobacco brand--sponsored activities, and distribution of samples. Financial incentives for club owners and staff were used to encourage smoking through peer influence. Increased use of these strategies occurred concurrently with an increase in smoking among persons aged 18 through 24 years. The tobacco industry's bar and nightclub promotions are not yet politically controversial and are not regulated by the 1998 Master Settlement Agreement between the industry and the states. Tobacco control advocates should include young adults in research and advocacy efforts and should design interventions to counter this industry strategy to solidify smoking patterns and recruit young adult smokers.

Overservice of alcohol (i.e., selling alcohol to intoxicated patrons) continues to be a problem at bars and restaurants, contributing to serious consequences such as traffic crashes and violence. We developed a training program for managers of bars and restaurants, eARM™, focusing on preventing overservice of alcohol. The program included online and face-to-face components to help create and implement establishment-specific policies. We conducted a large, randomized controlled trial in bars and restaurants in one metropolitan area in the midwestern United States to evaluate effects of the eARM program on the likelihood of selling alcohol to obviously intoxicated patrons. Our outcome measure was pseudo-intoxicated purchase attempts-buyers acted out signs of intoxication while attempting to purchase alcohol-conducted at baseline and then at 1 month, 3 months, and 6 months after training. We conducted intention-to-treat analyses on changes in purchase attempts in intervention (n = 171) versus control (n = 163) bars/restaurants using a Time × Condition interaction, as well as planned contrasts between baseline and follow-up purchase attempts. The overall Time × Condition interaction was not statistically significant. At 1 month after training, we observed a 6% relative reduction in likelihood of selling to obviously intoxicated patrons in intervention versus control bars/restaurants. At 3 months after training, this difference widened to a 12% relative reduction; however, at 6 months this difference dissipated. None of these specific contrasts were statistically significant (p = .05). The observed effects of this enhanced training program are consistent with prior research showing modest initial effects followed by a decay within 6 months of the core training. Unless better training methods are identified, training programs are inadequate as the sole approach to reduce overservice of alcohol.

Introduction Smoking is generally not regulated in restaurants or bars in China, or the restrictions are not fully implemented if there are any, while the related hazard health effects are not recognized by the majority of the Chinese population. Objectives This study aims to assess the excess health risks and mortality attributed to secondhand smoke (SHS) exposure in restaurants and bars for both servers and patrons to provide necessary evidence for advancing tobacco control in this microenvironment. Methods Two approaches were used for the assessment. One is a continuous approach based on existing field measurements and Repace and Lowrey’s dose-response model, and the other is a categorical approach based on exposure or not and epidemiological studies. Results Based on the continuous approach, servers were estimated to have a lifetime excess risk (LER) of lung cancer death (LCD) of 730 to 1,831×10−6 for working five days a week for 45 years in smoking restaurants and 1,862 to 8,136×10−6 in smoking bars, and patrons could have a LER of LCD of 47 to 117×10−6 due to visiting smoking restaurants for an average of 13 minutes a day for 60 years, and 119 to 522×10−6 due to visiting smoking bars. The categorical approach estimated that SHS exposure in restaurants and bars alone caused 84 LCD and 57 ischemic heart disease (IHD) deaths among nonsmoking servers and 1,2419 LCDs and 1,689 IHD deaths among the nonsmoking patron population. Conclusions SHS exposure in restaurants and bars alone can impose high lifetime excess risks of lung cancer death and ischemic heart disease deaths to both servers and patrons, and can cause a significant number of deaths each year in China. These health risks and deaths can be prevented by banning smoking in restaurants and bars and effectively implementing these smoking bans. PMID:24416289

Bar patronage and motivational predictors of drinking in the San Francisco Bay Area: Gender and sexual identity differences

Prior research has found differences in heavier drinking by both gender and sexual orientation. Heavier drinking and alcohol-related problems appear to be higher in sexual minority populations, particularly among women. It has been suggested that differences may be explained in part by socializing in bars and other public drinking venues. This paper explores bar patronage, alcohol consumption, alcohol-related problems, and reasons for going to bars in relation to both gender and sexual orientation based on two different samples: respondents from a random digit dial (RDD) probability study of 1,043 households in Northern California and 569 individuals who were surveyed exiting from 25 different bars in the same three counties that constituted the RDD sample. Bar patrons, in most instances, regardless of gender or sexual identity were at much higher risk of excessive consumption and related problems and consequences. On several key variables, women from the bar patron sample exceeded the problem rates of men in the general population. Bisexual women and men were elevated on a majority of the alcohol measures relative to heterosexuals. Measures of heavier drinking and alcohol-related problems were also elevated among lesbians compared to heterosexual women. Lesbian and gay respondents were less likely to endorse various motives as being important to their bar patronage. Finally, two of the bar motive variables, sensation seeking and mood change motives, were particularly predictive of heavier drinking and alcohol-related problems. Social motives did not predict problems. The findings suggest that bar patrons constitute a population of individuals who require special attention in prevention and intervention that should be tailored to their interests while taking into consideration their unique motivational needs.

Exemptions for hookah bars in clean indoor air legislation: a public health concern.

PubMed

Noonan, Devon

2010-01-01

Popularity of waterpipe smoking or hookah smoking in the United States has been growing for some time now among youth and young adults. Currently, many cities and states have exemptions that allow hookah bars to remain in operation despite the passage of clean indoor air legislation. From a public health perspective this is concerning for many reasons. One public health concern with the increase in popularity of this type of tobacco use is the associated health effects. Another concern is that hookah smoke produces a sweet smelling aroma making it less obvious that patrons and employees of hookah bars are inhaling noxious fumes from mainstream smoke, as well as the toxins from the charcoal that is used to heat the tobacco. The purpose of this paper is to discuss smoke-free air legislation in relation to hookah use, the public health implications of exempting hookah bars from current smoke-free legislation, and implications for the public health nurse in protecting the public from the dangers of second-hand smoke, and limiting this new form of tobacco use.

Can obviously intoxicated patrons still easily buy alcohol at on-premise establishments?

Background Excessive alcohol consumption at licensed alcohol establishments (i.e., bars and restaurants) has been directly linked to alcohol-related problems such as traffic crashes and violence. Historically, alcohol establishments have had a high likelihood of selling alcohol to obviously intoxicated patrons (also referred to as “overservice”) despite laws prohibiting these sales. Given the risks associated with overservice and the need for up-to-date data, it is critical that we monitor the likelihood of sales to obviously intoxicated patrons. Methods To assess the current likelihood of a licensed alcohol establishment selling alcohol to an obviously intoxicated patron, we conducted pseudo-intoxicated purchase attempts (i.e., actors attempt to purchase alcohol while acting out obvious signs of intoxication) at 340 establishments in one Midwestern metropolitan area. We also measured characteristics of the establishments, the pseudo-intoxicated patrons, the servers, the managers, and the neighborhoods to assess whether these characteristics were associated with likelihood of sales of obviously intoxicated patrons. We assessed these associations with bivariate and multivariate regression models. Results Pseudo-intoxicated buyers were able to purchase alcohol at 82% of the establishments. In the fully adjusted multivariate regression model, only one of the characteristics we assessed was significantly associated with likelihood of selling to intoxicated patrons–establishments owned by a corporate entity had 3.6 greater odds of selling alcohol to a pseudo-intoxicated buyer compared to independently-owned establishments. Discussion Given the risks associated with overservice of alcohol, more resources should be devoted first to identify effective interventions for decreasing overservice of alcohol and then to educate practitioners who are working in their communities to address this public health problem.

To examine the impact of smoke-free policies on revenue in Tasmanian bars. Monthly sales turnover from January 2002 to March 2007, provided by the Australian Bureau of Statistics was analysed. There were two (1) the ratio of monthly bar sales turnover in Tasmania to monthly bar sales turnover in four other Australian states, and (2) the ratio of monthly bar turnover to monthly retail turnover in Tasmania. Linear regression was used to assess the impact of the smoke-free policy on expenditure. The smoke-free policy had no effect on sales turnover. The smoke-free policy protects hospitality workers and patrons from exposure to secondhand smoke and has had no adverse effect on sales turnover.

2002-01-01

This study examined changes in tobacco promotions in the alternative press in San Francisco and Philadelphia from 1994 to 1999. A random sample of alternative newspapers was analyzed, and a content analysis was conducted. Between 1994 and 1999, numbers of tobacco advertisements increased from 8 to 337 in San Francisco and from 8 to 351 in Philadelphia. Product advertisements represented only 45% to 50% of the total; the remaining advertisements were entertainment-focused promotions, mostly bar-club and event promotions. The tobacco industry has increased its use of bars and clubs as promotional venues and has used the alternative press to reach the young adults who frequent these establishments. This increased targeting of young adults may be associated with an increase in smoking among this group.

To collect data on tobacco brand visibility on packaging on outdoor tables at bars/cafes in a downtown area, prior to a proposed plain packaging law. The study was conducted in the Central Business District of Wellington City in March 2014. Observational data were systematically collected on tobacco packaging visibility and smoking by patrons at 55 bars/cafes with outdoor tables. A total of 19,189 patrons, 1707 tobacco packs and 1357 active smokers were observed. One tobacco pack was visible per 11.0 patrons and the active smoking prevalence was 7.1% (95%CI: 4.9-9.2%), similar to Australian results (8.3%). Eighty percent of packs were positioned face-up (showing the brand), 8% face-down (showing the large pictorial warning), and 12% in other positions. Pack visibility per patron was significantly greater in areas without child patrons (RR=3.1, p<0.0001). Both smoking and pack visibility tended to increase from noon into the evenings on weekends. Inter-observer reliability for key measures in this study was high (Bland-Altman plots). Tobacco branding on packaging was frequently visible because of the way smokers position their packs. These results highlight the residual problem posed by this form of marketing. The results also provide baseline data for the future evaluation of plain packaging if a proposed law is implemented in New Zealand. Other results warrant further research, particularly the reasons for lower pack visibility and smoking when children were present.

St. René: the Patron Saint of Anaesthetists and a Patron Saint of Canada.

PubMed

Calverley, R K

1980-01-01

René Goupil, the Patron Saint of Anaesthetists, and a Patron Saint of Canada, was born in Angers, France in 1608 and studied surgery. He joined the Jesuits as a donné or volunteer worker in 1640 and served in the then tiny colony of Quebec as one of the first medical workers of Canada. After earning meritorious praise for his skills, he again volunteered to attend the Hurons at Sainte Marie, a mission far beyond the frontiers. René's canoe party was ambushed. He was captured by the Mohawks and endured eight weeks of cruel torture before being killed on September 29, 1642. René was the first of eight North American martyrs whose dedication was recognized by canonization in 1930. St. René was appointed Patron Saint of Anaesthetists in 1951.

This study aimed to assess the prevalence of amoebiasis among patrons visiting gay saunas in Taiwan. A cross-sectional survey was conducted using questionnaire interview and indirect hemagglutination assays and specific Entamoeba histolytica antigen assays of blood and rectal swab specimens, respectively, among patrons visiting 10 gay saunas between September 2006 and December 2006. During the three-month study period, 208 blood and 120 rectal swab specimens were tested for E. histolytica infection. Amoebiasis was detected among 3.8% and 3.3% of the patrons by serologies and antigen assays, respectively. During the latest sexual encounter, more than 70% of the patrons had oral-anogenital sex, and only 20% used condoms during oral-anogenital contact. Our findings suggest that there is a potential risk of E. histolytica transmission among the patrons visiting gay saunas who do not practise safe sex consistently in Taiwan.

Patron Banning in the Nightlife Entertainment Districts: A Key Informant Perspective.

Miller, Peter; Curtis, Ashlee; Palmer, Darren; Warren, Ian; McFarlane, Emma

2016-07-01

Alcohol-related harm in and around licensed venues is associated with substantial costs. Many interventions have been introduced in an effort to combat these harms, and one such intervention is known as patron banning. Patron banning involves prohibiting patrons who have been violent or disorderly in a licensed venue in an attempt to reduce alcohol-related harm. It can be implemented by the venue, by members of police, or by liquor accords. This study aimed to obtain key informant perspectives on the benefits of patron banning as well as on the effectiveness of patron banning in reducing alcohol-related harm. Thirty-six key informants provided perspectives on patron banning through in-depth interviews that were part of a larger study. Key informants were supportive of patron banning for reducing alcohol-related harm, noting that it had many benefits including increased venue safety, general risk management, and deterrence of antisocial behavior. Although processes for banning were not always consistent, identification scanners were generally recognized as a way to ensure that patron banning was enforced. Key informants viewed patron banning as an effective measure for increasing patron safety and reducing alcohol-related harms.

A field experiment was conducted in order to test the assumptions by the Supreme Court in Barnes v. Glen Theatre, Inc. (1991) and the Ninth Circuit Court of Appeals in Colacurcio v. City of Kent (1999) that government restrictions on dancer nudity and dancer-patron proximity do not affect the content of messages conveyed by erotic dancers. A field experiment was conducted in which dancer nudity (nude vs. partial clothing) and dancer-patron proximity (4 feet; 6 in.; 6 in. plus touch) were manipulated under controlled conditions in an adult night club. After male patrons viewed the dances, they completed questionnaires assessing affective states and reception of erotic, relational intimacy, and social messages. Contrary to the assumptions of the courts, the results showed that the content of messages conveyed by the dancers was significantly altered by restrictions placed on dancer nudity and dancer-patron proximity. These findings are interpreted in terms of social psychological responses to nudity and communication theories of nonverbal behavior. The legal implications of rejecting the assumptions made by the courts in light of the findings of this study are discussed. Finally, suggestions are made for future research.

The effects of 15 d polydextrose (16.7 g) consumption on energy intake (EI) and appetite feelings were investigated. Overweight adults consumed a polydextrose-bar or a control-bar matched in energy content as a midmorning snack for 15 consecutive days in a single-blind, randomised, crossover design. The two 15-d intervention periods were separated by a 15-d washout period. On the day 1 and the day 15 of each intervention period, energy intake (primary outcome) and appetite feelings (secondary outcome) were assessed. There were not significant main effects of the day, type of bar, or their interaction for EI (at lunchtime test meal, at rest of the day, or at total daily) or subjective feelings (hunger, desire to eat, fullness, and prospective food consumption) during the satiation and satiety periods. The results showed the consumption of polydextrose-bar during 15 d did not significantly affect energy intake and subjective feelings of appetite in overweight adults.

Games and gambling involvement among casino patrons.

A growing literature is addressing the nature of the relationships among gambling activity, gambling involvement, and gambling-related problems. This research suggests that among the general population, compared to playing any specific game, gambling involvement is a better predictor of gambling-related problems. To date, researchers have not examined these relationships among casino patrons, a population that differs from the general population in a variety of important ways. A survey of 1160 casino patrons at two Las Vegas resort casinos allowed us to determine relationships between the games that patrons played during the 12 months before their casino visit, the games that patrons played during their casino visit, and patrons' self-perceived history of gambling-related problems. Results indicate that playing specific gambling games onsite predicted (i.e., statistically significant odds ratios ranging from .5 to 4.51) self-perceived gambling-related problems. However, after controlling for involvement, operationally defined as the number of games played during the current casino visit and self-reported gambling frequency during the past 12 months, the relationships between games and gambling-related problems disappeared or were attenuated (i.e., odds ratios no longer statistically significant). These results extend the burgeoning literature related to gambling involvement and its relationship to gambling-related problems.

Restaurant initiatives provide an efficient opportunity to impact large numbers of patrons. The purpose of this study is to measure patron purchasing behaviors during the ¡Por Vida! menu designation initiative. This study used a cross-sectional design and survey data to assess 23 restaurants throughout Bexar County and 152 restaurant patrons. The Patron Awareness Questionnaire assessed if patrons noticed the logo; believed nutrition, cost, and taste were important in making purchasing decisions; and purchased a ¡Por Vida! item. Descriptive statistics, Spearman correlations, and logistic regression were used to analyze the data. Most (93.4%) patrons considered taste very important when deciding what to eat. Cost was very important to 63.8% and nutrition was very important to 55.9% of the sample. The strongest predictors of purchasing a ¡Por Vida! item were the patrons' ages being between 18 and 35 years (odds ratio = 1.474; confidence interval = 0.017, 0.812; p < .05) and if patrons saw the logo (odds ratio = 4.327; confidence interval = 1.696-11.036; p < .01). Menu logo designation initiatives can potentially influence patron purchasing behaviors among a segment of the population when the logo is visible.

Irresponsible and illegal serving practices at bars and restaurants, such as sales to obviously intoxicated patrons, can lead to various public health harms. Training managers of bars and restaurants in the development and promotion of responsible alcohol policies may help prevent risky and illegal alcohol serving practices. We implemented a training program for managers of bars/restaurants designed to establish and promote responsible beverage service policies/practices. The program included online and in-person components. Bars/restaurants were randomised to intervention (n = 171) and control (n = 163) groups. To assess changes in policies/practices, we surveyed managers prior to and at 1 and 6 months post-training. Logistic regression models assessed changes in policies/practices across time points. The proportion in the intervention group that had written alcohol policies increased from 62% to 95% by 6 months post-training while the control group increased from 65% to 79% (P < 0.05). Similarly, by 6 months post-training 70% of managers in the intervention group reported they had communicated to their staff how to cut off intoxicated patrons, a significant increase from baseline (37%) and from the change observed in the control group (43%-56%). Prevalence of other policies/practices also increased post-training but differences between intervention and control groups were not statistically significant. Our training program appears to have led to implementation of some policies/practices. Additional studies are needed to determine how training can be combined with other strategies to further improve establishment policies and ultimately reduce alcohol-related harms. © 2017 Australasian Professional Society on Alcohol and other Drugs.

Analysis of commode grab bar usage for the monitoring of older adults in the smart home environment.

2009-01-01

The occurrence of falls inside the home is a common yet potentially hazardous issue for adults as they age. Even with the installation of physical aids such as grab bars, weight transfers on and off a toilet or bathtub can become increasingly difficult as a person's level of physical mobility and sense of balance deteriorate. Detecting this deterioration becomes an important goal in fall prevention within a smart home. This paper develops an unobtrusive method of analyzing the usage of toilet grab bars using pressure sensors embedded into the arm rests of a commode. Clinical parameters are successfully extracted automatically from a series of stand-to-sit (StSi) and sit-to-stand (SiSt) transfers performed by a trial group of young and older adults. A preliminary comparison of the parameters indicates differences between the two groups, and aligns well with published characteristics obtained using accelerometers worn on the body. The unobtrusive nature of this method provides a useful tool to be incorporated into a system of continuous monitoring of older adults within the smart home environment.

The relationship between group size, intoxication and continuing to drink after bar attendance.

Reed, Mark B; Clapp, John D; Martell, Brandi; Hidalgo-Sotelo, Alexandra

2013-11-01

The present study was undertaken to explore multilevel determinants of planning to continue to drink alcohol after leaving public drinking events. We assessed whether individual-level factors, group-related factors, or event-level bar characteristics were associated with post-bar drinking. We recruited a total of 642 participants from 30 participating bars in urban Southern California. Groups who arrived to patron a bar were interviewed upon their entrance and exit. Given data nesting, we employed a multilevel modeling approach to data analysis. More than one-third (40%) of our sample reported the intention to continue drinking as they exited the bar. Results of our multilevel model indicated eight individual-level variables significantly associated with intending to continue to drink. Time of night moderated the relationship between BrAC change and intentions to continue to drink. Although none of the group factors were significant in our model, a significant cross-level interaction between BrAC change and number of group members indicated the effect of intoxication on planning to continue to drink increases as group members increase. At the bar level, the presence of temporary bars and server offers of non-alcoholic drinks significantly decreased intentions to continue to drink. Given the large percentage of participants who reported the intention to continue drinking after exiting a bar, this study draws attention to the fact that field studies of drinking behavior may assess drinking mid-event rather than at the end of a drinking event.

Oligofructose is a prebiotic dietary fibre obtained from chicory root inulin. Oligofructose supplementation may affect satiety, food intake, body weight and/or body composition. The aim was to examine the efficacy of oligofructose-supplemented granola bars on the following weight management outcomes: satiety, energy intake, body weight and body composition in overweight or obese adults. In all, fifty-five adults with overweight or obesity (thirty-six females/nineteen males; age: 41 (sd 12) years; 90·6 (sd 11·8) kg; BMI: 29·4 (sd 2·6) kg/m2) participated in a parallel, triple-blind, placebo-controlled intervention. A total of twenty-nine subjects replaced their snacks twice a day with an equienergetic granola bar supplemented with 8 g of oligofructose (OF-Bar). Subjects in the control group (n 26) replaced their snack with a control granola bar without added oligofructose (Co-Bar). Satiety, 24-h energy intake, body weight and body composition (fat mass and waist circumference) were measured at baseline, weeks 6 and 12. In addition, weekly appetite and gastrointestinal side effects were measured. During the intervention, energy intake, body weight and fat mass remained similar in the Co-Bar and OF-Bar groups (all P>0·05). Both groups lost 0·3 (sd 1·2) kg lean mass (P<0·01) and reduced their waist circumference with -2·2 (sd 3·6) cm (P<0·0001) after 12 weeks. The OF-Bar group reported decreased hunger in later weeks of the intervention (P=0·04), less prospective food consumption (P=0·03) and less thirst (P=0·003). To conclude, replacing daily snacks for 12 weeks with oligofructose-supplemented granola bars does not differentially affect energy intake, body weight and body composition compared with a control bar. However, there was an indication that appetite was lower after oligofructose bar consumption.

To document the nature and prevalence of tobacco promotions in bars and clubs in a major US city. We conducted systematic observations in a representative sample of 38 establishments in the Boston area, half of which had been advertised in a tobacco company ad. We also observed seven events in six additional clubs hosting Camel Casbah promotions. Telephone interviews were later completed with club managers. Use of branded give-away items, distribution of free cigarette samples, managers' reports of costs and benefits of hosting promotions. The majority of the 38 clubs were observed to use bar paraphernalia including matchbooks with tobacco brand logos, regardless of their history of appearing in tobacco sponsored ads. Free cigarette samples were not observed at any of the sampled clubs, but were a feature of every Casbah event. Managers of clubs in the advertised group were somewhat more likely to report having hosted promotions, but 44% of managers of non-advertised clubs indicated that tobacco promotions had occurred in their establishments in the past. Approximately one third of club managers viewed public links with a tobacco company as a negative feature of hosting promotions. Based on managers' reports, tobacco promotions occurred in more than 50% of the Boston area entertainment venues frequented by young adults. Cigarette companies should be required to inform the attorney general of plans to conduct promotions in adult-only venues to facilitate monitoring of compliance with the Master Settlement Agreement. The negative health and business consequences of hosting promotions should be communicated to bar owners.

Delfabbro, Paul; Borgas, Mignon; King, Daniel

In several jurisdictions around the world, venue staff are encouraged to make reasonable attempts to determine whether patrons may be experiencing problems associated with their gambling. Although a number of visible indicators and behaviours are recognised as being indicative of gambling problems, no research has investigated how effective staff might be in identifying problem gamblers in venues. The aim of this field test was to examine the level of patron familiarity amongst staff working in small to moderate-sized venues. Patrons (n = 303) were asked to complete a short survey including the Problem Gambling Severity Index and venue staff were asked to describe their knowledge of the same patrons independently. The results showed that patrons rated as more at risk by staff scored significantly higher on the PGSI, but that point-in-time staff ratings were not sufficiently accurate to allow effective identification of problem gamblers. The importance of using accumulated information over multiple sessions as well as technological monitoring of behaviour was emphasised by these results.

2006-03-14

New Zealand introduced a smokefree bars and restaurants policy in December 2004. We reviewed the data available at December 2005 on the main public health, societal and political impacts and responses within New Zealand to the new law. Data were collected from publicly available survey reports, and from government departments and interviews. This included data on smoking in bars, attitudes to smokefree bars, bar patronage, socially cued smoking, and perceived rights to smokefree workplaces. The proportion of surveyed bars with smoking occurring decreased from 95% to 3% during July 2004-April 2005. Between 2004 and 2005, public support for smokefree bars rose from 56% to 69%. In the same period, support for the rights of bar workers to have smokefree workplaces rose from 81% to 91%. During the first ten months of the smokefree bars policy, there were only 196 complaints to officials about smoking in the over 9900 licensed premises. The proportion of smokers who reported that they smoked more than normal at bars, nightclubs, casinos and cafés halved between 2004 and 2005 (from 58% to 29%). Seasonally adjusted sales in bars and clubs changed little (0.6% increase) between the first three quarters of 2004 and of 2005, while café and restaurant sales increased by 9.3% in the same period. Both changes continued existing trends. Compared to the same period in 2004, average employment during the first three quarters of 2005 was up 24% for 'pubs, taverns and bars', up 9% for cafés/restaurants, and down 8% for clubs (though employment in 'pubs, taverns and bars' may have been affected by unusually high patronage around a major sports-series). The proportion of bar managers who approved of smokefree bars increased from 44% to 60% between November 2004 and May 2005. Bar managers also reported increased agreement with the rights of bar workers and patrons to smokefree environments.

Wagner, Gabriela A; Sanchez, Zila M

2017-05-01

Brazil has a strict drinking and driving law known as the Brazilian "Dry Law". The aim of the present study was to investigate characteristics associated with the breaking of the Brazilian traffic law, on drinking and driving, at nightclub exit among a representative sample of nightclub patrons in the city of São Paulo, Brazil. Portal survey realized with a two-stage cluster sampling survey design to collect data from 2422 patrons at the entrance and 1822 patrons at the exit of 31 nightclubs in the city of São Paulo, Brazil. Patrons' breath alcohol concentrations (BrACs) at the entrance and exit of the nightclubs were categorized according to the law as either a "traffic offense" or a "traffic offense and crime". Weighted multinomial logistic regression was used to analyze factors associated with different patterns of drinking and driving offenses. Of the subjects, 16.5% (n=369) were identified as driving patrons at the entrance and exit of the nightclubs. At entry, 80.1% of the patrons had a zero BrAC, 14.9% had a BrAC meeting the traffic offense criteria and 5.0% had a BrAC meeting the traffic offense and crime criteria. Women were less likely to have BrACs meeting the traffic offense criteria. At nightclub exit, 63.4% of patrons had maintained a zero BrAC, 24.7% had a BrAC that had increased and now met the traffic offense and crime criteria, and 11.9% had a decreased or stable BrAC. An increased BrAC was more frequently identified in patrons who were men, were single, and had used illicit drugs inside the nightclub. Despite the existence of a strict law regarding drinking and driving, a significant proportion of nightclub patrons in the city of São Paulo had violated this law, suggesting a perception of impunity and need for law enforcement.

Introduction Brief sexual encounters among consenting adults who patronize social venues such as karaoke bars are occurring more frequently in China, however, little is known about the characteristics of those who engage in “one-time-sex” with a non-commercial partner or the risk of sexually transmitted infection associated with a high rate of short-term non-commercial partnerships. Methods We surveyed and tested for evidence of syphilis 797 men and women at randomly selected social venues in urban Liuzhou, China and three surrounding counties. Results The proportion of respondents reporting recent non-commercial one-time-sex ranged from 14.5% of county women to 24.8% of urban men. More urban men reported one-time-sex with a noncommercial than with a commercial partner (24.8% vs. 14.2%). Approximately 5% of all respondents reported engaging in both non-commercial and commercial one-time-sex in the past year. Among men, 2.4% has a positive rapid syphilis test. Men reporting non-commercial one-time-sex were significantly more likely to have a positive rapid syphilis test than other men (7.4% vs. 0.9%). Among women, 3.7% has a positive syphilis test. A higher proportion of women reporting commercial sex had a positive test than those reporting non-commercial one-time-sex (6.0% vs 0.7%). Conclusions Recent one-time sex was common among persons socializing at entertainment venues. Venue-based HIV/STI prevention methods may be warranted among persons who do not engage in commercial sex, but frequently engage in one-time sex. PMID:24185709

2008-12-01

The purpose of this cross-sectional study was to examine the influence of the nutritional labeling Nutrition Bytes on the eating habits of adults eating in dining halls at a Midwestern university and to assess differences between sexes. Dining hall patrons (114 men, 91 women) 19 years of age or older voluntarily completed a descriptive 15-item written questionnaire that examined the use and nonuse of Nutrition Bytes, which contains much of the information included in the Nutrition Facts label. A significantly higher percentage of women than men patrons reported currently using Nutrition Bytes labels (P<0.001). Predominant reasons for using Nutrition Bytes labels were: general knowledge, concern about overall health, calorie counting, and concern about a certain nutrient(s). Predominant reasons given for not using Nutrition Bytes labels were: will not change my mind about food items selected and not enough time. Reasons given by men and women for using or not using Nutrition Bytes labels were similar. Significantly higher percentages of women than men using Nutrition Bytes labels indicated being interested in having serving sizes (P<0.005) and ingredients (P<0.0005) listed, whereas higher percentages of men than women indicated being interested in having protein listed (P<0.05). The percentages of users who indicated nearly always and sometimes changing their food choices after reading Nutrition Bytes labels inside the dining halls were 12% and 80%, respectively, whereas 23% and 65%, respectively, indicated changing their food choices after reading the nutrition label when eating outside the dining halls. Nutrition Bytes labeling seemed to positively impact food choices of these adult dining hall patrons, and likely would do so at other dining halls.

We assessed changes in levels of support for smoke-free bars and restaurants among teens and young adults before and after implementation of a statewide smoke-free law. We measured support for smoke-free bars and restaurants among teens and young adults aged 16-24 years living in Minnesota (n=2,785) and five comparison states (n=404), up to 12 months before and up to six months after Minnesota's smoke-free law went into effect in October 2007. We compared changes in support among three subgroups-Minnesota participants who lived with a previous local smoke-free law, Minnesota participants who did not live with a previous local smoke-free law, and participants from the comparison states-before and after Minnesota's statewide smoke-free law went into effect. Support for smoke-free restaurants and bars among participants in Minnesota and comparison states increased after Minnesota's smoke-free law went into effect. Minnesotans, both those living with and without a previous local smoke-free law, showed similar increases in support for smoke-free restaurants as participants in comparison states. However, Minnesotans living without a previous local law showed larger increases in support for smoke-free bars than both those in comparison states and those living in Minnesota with a previous local smoke-free law. Our study employed a more robust design than similar studies and focused on the teen and young adult population. Our results will help advocates and policy makers demonstrate how public support for smoke-free laws increases following smoke-free legislation, particularly among those who were not previously living with a local smoke-free law.

Objective Young adults frequently report social smoking. This study examined the relationship between different social smoking definitions and the co-use of cigarettes and alcohol, tobacco-related attitudes, and quitting efforts. Method Cross-sectional data were collected at bars using randomized time location sampling among young adults aged 21–26 in San Diego, CA from 2010–2011 (73% response rate). Multivariable logistic regression examined if current smoking and quit attempts were associated with tobacco-related attitudes, and whether social smoking self-identification or behavior was associated with cigarette-and-alcohol co-use, tobacco-related attitudes, quit attempts, or quitline use. Results Among 537 current smokers, 80% self-identified and 49% behaved as social smokers. Social smoking self-identification was positively associated with cigarette-and-alcohol co-use, and quit attempts. Social smoking behavior was negatively associated with tobacco marketing receptivity, quit attempts, quitline use.

Young adults frequently report social smoking. This study examined the relationship between different social smoking definitions and the co-use of cigarettes and alcohol, tobacco-related attitudes, and quitting efforts. Cross-sectional data were collected at bars using randomized time location sampling among young adults aged 21-26 in San Diego, California from 2010 to 2011 (73% response rate). Multivariable logistic regression examined if current smoking and quit attempts were associated with tobacco-related attitudes, and whether social smoking self-identification or behavior was associated with cigarette-and-alcohol co-use, tobacco-related attitudes, quit attempts, or quitline use. Among 537 current smokers, 80% self-identified and 49% behaved as social smokers. Social smoking self-identification was positively associated with cigarette-and-alcohol co-use, and quit attempts. Social smoking behavior was negatively associated with tobacco marketing receptivity, quit attempts, and quitline use. Tobacco-related attitudes were associated with smoking but did not generally differ by social smoking status. Identification and behavior as a social smoker have opposing associations with co-use of cigarettes and alcohol and quit attempts. Tobacco cessation programs for self-identified social smokers should address co-use. Interventions denormalizing the tobacco industry or emphasizing the health effects of temporary smoking and secondhand smoke may address smoking among young adult bar patrons regardless of social smoking status.

Smoke-free air laws in restaurants and bars protect patrons and workers from involuntary exposure to secondhand smoke, but owners often express concern that such laws will harm their businesses. The primary objective of this study was to estimate the association between local smoke-free air laws and economic outcomes in restaurants and bars in 8 states without statewide smoke-free air laws: Alabama, Indiana, Kentucky, Mississippi, Missouri, South Carolina, Texas, and West Virginia. A secondary objective was to examine the economic impact of a 2010 statewide smoke-free restaurant and bar law in North Carolina. Using quarterly data from 2000 through 2010, we estimated dynamic panel data models for employment and sales in restaurants and bars. The models controlled for smoke-free laws, general economic activity, cigarette sales, and seasonality. We included data from 216 smoke-free cities and counties in the analysis. During the study period, only North Carolina had a statewide law banning smoking in restaurants or bars. Separate models were estimated for each state. In West Virginia, smoke-free laws were associated with a significant increase of approximately 1% in restaurant employment. In the remaining 8 states, we found no significant association between smoke-free laws and employment or sales in restaurants and bars. Results suggest that smoke-free laws did not have an adverse economic impact on restaurants or bars in any of the states studied; they provided a small economic benefit in 1 state. On the basis of these findings, we would not expect a statewide smoke-free law in Alabama, Indiana, Kentucky, Missouri, Mississippi, South Carolina, Texas, or West Virginia to have an adverse economic impact on restaurants or bars in those states.

Young adulthood (ages 18-25 years) represents a time when high-risk behaviors, including alcohol and drug use, peak. Electronic music dance events (EMDEs) featured at clubs provide an ecologic niche for these high-risk behaviors. This paper examines the prevalence of alcohol and drug use among EMDE patrons. Examination of personal characteristics associated with exit levels of alcohol and drug use identifies important indicators of risk taking for prevention strategies. Data were collected anonymously during 2010-2012 from 2028 patrons as they entered and exited clubs in the San Francisco Bay area featuring EMDEs. Nearly half were aged ≤25 years. Biological measures of drug and alcohol and self-reported personal characteristics were attained. Analyses were completed in 2012. At entrance, more than one fifth of patrons were positive for drug use and one fourth arrived either impaired (blood alcohol concentration [BAC]: 0.05%-0.079%) or intoxicated (BAC: >0.08%) by alcohol. At exit, one fourth tested positive for drugs, and nearly half were impaired or intoxicated by alcohol. Individual characteristics that were important for levels of risk included prior alcohol use behaviors, sexual identity, ethnic/racial identity, and transportation to the event. Gender did not differentiate for alcohol use but fewer women used drugs. Findings confirm the importance of targeting EMDEs for prevention efforts. EMDEs attract young working adults who are engaged in heavy alcohol and/or drug use. Targeting these social settings for delivering public health prevention strategies regarding alcohol and drug use and related harm is indicated by the findings. © 2013 American Journal of Preventive Medicine.

Restaurant menu labeling: impact of nutrition information on entree sales and patron attitudes.

PubMed

Albright, C L; Flora, J A; Fortmann, S P

1990-01-01

This study examined changes in sales of low fat/low cholesterol foods targeted in a restaurant menu labeling program. Sales of labeled items were tracked before and after the program was introduced, and a subsample of patrons were surveyed for information on visibility and comprehension of the menu labels. Two of the four restaurants had significant increases in the sales of targeted foods following labeling. Comparisons between patrons dining in restaurants which had an increase in sales (I--increase restaurants) to those dining in restaurants which had no overall shift in sales (NI--no increase restaurants) revealed no differences in patron awareness or comprehension of the menu labels. There were age and gender differences between I and NI restaurants, with I restaurants having proportionally more males, and a younger clientele. Taste was the primary reason given by patrons for their entree choice, regardless of whether or not it was labeled. In all four restaurants women and older patrons were more aware of the program and more responsive to its recommendations. These findings suggest that environmental strategies may be an effective method of encouraging dietary changes in the general population, but patron characteristics such as age and gender may influence receptivity to this type of intervention. Future studies aimed at developing effective point of purchase education programs should evaluate these patron characteristics and include more powerful behavior change strategies.

While alcohol-related harm is reportedly greater on weekend evenings, research investigating trends in the intoxication levels of patrons and factors that increase risk of harm over the night is lacking. The aim was to observe trends over the course of the night for patron demographics, venue characteristics and patron intoxication. Observations of licensed venues and patrons in night-time entertainment districts of five Australian cities were conducted. In total, 798 observations occurred between 9 pm and 2 am on Friday and Saturday nights across 61 unique bars, nightclubs, and pubs. Patron characteristics such as gender and percentage of patrons under 25 years of age were estimated. Measures of venue characteristics included number of patrons, percentage venue capacity, ease of patron movement, bar crowding, and time to service. Measures of intoxication included the percentage of patrons showing any signs of alcohol intoxication, percentage of patrons too intoxicated to remain in the venue, overall level of intoxication, and percentage of patrons showing signs of drug use. Patron capacity increased across the night, peaking at 11 pm in bars, and 1 am in nightclubs. Patron intoxication measures increased for all venue types across the night. Patrons showed more signs of drug use in nightclubs than other venue types. Increasing intoxication and decreasing patron numbers later in the night provides support for restricted trading hours and improved responsible service of alcohol policies. Specific venue types should be targeted to reduce drug use in the night-time economy.

2014-03-01

To assess the prevalence of sex work and its associations with substance use among female bar/spa workers in the Philippines (N = 498), workers from 54 bar or spa venues in Metro Manila (2009-2010) were surveyed on demographics, drug/alcohol use, abuse history, and sex work. Their median age was 23 years and 35% engaged in sex work. Sex work was independently associated with methamphetamine use (19% vs 4%; adjusted odds ratio [AOR] =2.9, 95% confidence interval [CI] = 1.3-6.2), alcohol use with patrons (49% vs. 27%; AOR = 1.9, 95% CI = 1.1-3.4), and alcohol intoxication during sex (50% vs. 24%; AOR = 2.0, 95% CI = 1.2-3.5), but inversely associated with daily alcohol use (13% vs. 16%; AOR = 0.2, 95% CI = 0.1-0.5). Additional significant covariates included sexual abuse history, younger age, and not having a higher education. Findings suggest that interventions with sex workers in bars and spas should focus on methamphetamine use, alcohol use contexts, and violence victimization, to better meet the needs of this population.

Alcohol sales to intoxicated patrons are illegal and may lead to public health issues such as traffic crashes and violence. Over the past several decades, considerable effort has been made to reduce alcohol sales to underage persons but less attention has been given to the issue of sales to obviously intoxicated patrons. Studies have found a high likelihood of sales to obviously intoxicated patrons (i.e., overservice), but little is known about efforts by enforcement agencies to reduce these sales. We conducted a survey of statewide alcohol enforcement agencies and local law enforcement agencies across the U.S. to assess their strategies for enforcing laws prohibiting alcohol sales to intoxicated patrons at licensed alcohol establishments. We randomly sampled 1,631 local agencies (1082 participated), and surveyed all 49 statewide agencies that conduct alcohol enforcement. Sales to obviously intoxicated patrons were reported to be somewhat or very common in their jurisdiction by 55% of local agencies and 90% of state agencies. Twenty percent of local and 60% of state agencies reported conducting enforcement efforts to reduce sales to obviously intoxicated patrons in the past year. Among these agencies, fewer than half used specific enforcement strategies on at least a monthly basis to prevent overservice of alcohol. Among local agencies, enforcement efforts were more common among agencies that had a full-time officer specifically assigned to carry out alcohol enforcement efforts. Enforcement of laws prohibiting alcohol sales to obviously intoxicated patrons is an underutilized strategy to reduce alcohol-related problems, especially among local law enforcement agencies.

Bar dimensions and bar shapes in estuaries

NASA Astrophysics Data System (ADS)

Leuven, Jasper; Kleinhans, Maarten; Weisscher, Steven; van der Vegt, Maarten

Estuaries cause fascinating patterns of dynamic channels and shoals. Intertidal sandbars are valuable habitats, whilst channels provide access to harbors. We still lack a full explanation and classification scheme for the shapes and dimensions of bar patterns in natural estuaries, in contrast with bars in rivers. Analytical physics-based models suggest that bar length in estuaries increases with flow velocity, tidal excursion length or estuary width, depending on which model. However, these hypotheses were never validated for lack of data and experiments. We present a large dataset and determine the controls on bar shape and dimensions in estuaries, spanning bar lengths from centimeters (experiments) to 10s of kilometers length. First, we visually identified and classified 190 bars, measured their dimensions (width, length, height) and local braiding index. Data on estuarine geometry and tidal characteristics were obtained from governmental databases and literature on case studies. We found that many complex bars can be seen as simple elongated bars partly cut by mutually evasive ebb- and flood-dominated channels. Data analysis shows that bar dimensions scale with estuary dimensions, in particular estuary width. Breaking up the complex bars in simple bars greatly reduced scatter. Analytical bar theory overpredicts bar dimensions by an order of magnitude in case of small estuarine systems. Likewise, braiding index depends on local width-to-depth ratio, as was previously found for river systems. Our results suggest that estuary dimensions determine the order of magnitude of bar dimensions, while tidal characteristics modify this. We will continue to model bars numerically and experimentally. Our dataset on tidal bars enables future studies on the sedimentary architecture of geologically complex tidal deposits and enables studying effects of man-induced perturbations such as dredging and dumping on bar and channel patterns and habitats.

Drinking before entering nightclubs (predrinking) seems to be associated with an increase in alcohol-related harm. This study aims to investigate gender differences in predrinking behavior and to evaluate its association with risk behaviors practiced inside nightclubs. Individual-level data were collected by a portal survey of 2,422 patrons at the entrance and 1,833 patrons at the exit of 31 nightclubs located at São Paulo, Brazil. The nightclubs were selected by 2-stage sampling with probability proportional to the establishments' capacity in the first stage and a systematic sample of patrons in the entrance line in the second stage. Breath alcohol concentration (BrAC) was measured at the entrance and exit. Face-to-face interviews identified predrinking characteristics and risk behaviors. Weighted analyses were stratified by gender. Predrinking was practiced by 49.2% (95% confidence interval [CI] = 42.7 to 55.8) of the male patrons and 29.0% (95% CI = 20.6 to 38.9) of the female patrons (p < 0.001) on the day of the interview. When considering only predrinkers, men and women showed similar BrAC at entrance and exit and similar proportion of alcoholic intoxication (BrAC ≥ 0.38 mg/l). In both genders, people who practiced predrinking on the day of the interview were more likely to drink inside the nightclub, compared to those who did not practice predrinking (p < 0.001). Among men, the practice of predrinking increased the chance of "drinking and driving" after leaving the nightclub (odds ratio [OR] = 6.9, 95% CI = 4.1-11.5, p < 0.001). Among women, the practice of predrinking increased the chances of experiencing sexual harassment in the nightclub (OR = 2.9, 95% CI = 1.3 to 6.6, p = 0.010). Predrinking is more prevalent among men; however, men and women who engaged in predrinking have a similar pattern of alcohol consumption and exit BrAC.

2013-01-01

Objective Little systematic research has focused on motivations for aggression and most of the existing research is qualitative and atheoretical. This study increases existing knowledge by using the theory of coercive actions to quantify the apparent motives of individuals involved in barroom aggression. Objectives were to examine: gender differences in the use of compliance, grievance, social identity, and excitement motives; how motives change during an aggressive encounter; and the relationship of motives to aggression severity. Method We analyzed 844 narrative descriptions of aggressive incidents observed in large late-night drinking venues as part of the Safer Bars evaluation. Trained coders rated each type of motive for the 1,507 bar patrons who engaged in aggressive acts. Results Women were more likely to be motivated by compliance and grievance, many in relation to unwanted sexual overtures from men; whereas men were more likely to be motivated by social identity concerns and excitement. Aggressive acts that escalated tended to be motivated by identity or grievance, with identity motivation especially associated with more severe aggression. Conclusions A key factor in preventing serious aggression is to develop approaches that focus on addressing identity concerns in the escalation of aggression and defusing incidents involving grievance and identity motives before they escalate. In bars, this might include training staff to recognize and defuse identity motives and eliminating grievance-provoking situations such as crowd bottlenecks and poorly managed queues. Preventive interventions generally need to more directly address the role of identity motives, especially among men. PMID:24224117

Impact of US smoke-free air laws on restaurants and bars by employer size: a panel study

PubMed Central

2017-01-01

Objectives Thirty states have smoke-free air laws that ban smoking in restaurants and bars, covering nearly two-thirds of the US population. It is well established that these laws generally have a null or positive economic impact on restaurants and bars. However, all establishments in a geographic area are usually treated as a homogeneous group without considering the potential for differential effects by establishment characteristics. This study uses variation in smoke-free air laws over time to estimate their impact on employment in restaurants and bars with a focus on potential differences by employer size (number of employees). A two-pronged approach with a national-level and state-level analysis is used to take advantage of more granular data availability for a single state (North Carolina). Design Observational study using panel data. Setting 1) US, 2) North Carolina Interventions Smoke-free air laws. Outcome measures State-level accommodation and food services employment for all 50 states and District of Columbia from 1990 through 2014 (Quarterly Census of Employment and Wages); county-level restaurant and bar employment in North Carolina from 2001 through 2014 (North Carolina Department of Commerce). Results There is no evidence of a redistributive effect of smoke-free air laws on restaurant and bar employment by employer size. Conclusion The lack of a redistributive effect is an important finding for policy-makers considering implementation or expansion of a smoke-free air law to protect employees and patrons from the dangers of exposure to secondhand smoke.

In 2006, the World Health Organization Framework Convention on Tobacco Control became effective in mainland China. In 2007, advocacy on voluntary smoking bans in restaurants was initiated in Beijing, and in 2008 the Beijing government implemented a smoking regulation, requiring big restaurants to prohibit or restrict smoking. To evaluate the efficacy of different smoking policies adopted by Beijing restaurants and bars from 2006 to 2010. The study conducted field observations of patron smoking behavior and monitored fine particulate matter from secondhand smoke (SHS PM) from 91, 85, 94 and 79 Beijing restaurants and bars in 2006, 2007, 2008 and 2010, respectively, during peak-patronage times, with overlaps of venues during each two years. Area nicotine sampling during peak patronage times and servers' personal nicotine sampling during their working shifts were also conducted in 2010. Smoking was nominally prohibited or restricted in 18% of restaurants and bars monitored in 2006, in 11% of venues in 2007, in 83% of venues in 2008, and in 69% of venues in 2010. However, smoking was observed in more than 40% of the nominal nonsmoking venues/sections in 2008 and 2010. The median of observed patron active smoker density (ASD) was 0.24, 0.27, 0.00 and 0.10 active smokers per 100 m3 in 2006, 2007, 2008 and 2010, respectively. The median of SHS PM concentrations was 53, 83, 18 and 27 μg/m3, respectively. In 2010, both the median SHS PM and air nicotine concentrations in designated nonsmoking sections were about 40% of those in designated smoking sections, according to simultaneous sampling in both sections. Servers' personal exposure to air nicotine was quite similar in venues with different nominal smoking policies. In the 15 venues followed from 2006 to 2010, SHS PM concentrations changed randomly from 2006 to 2007, decreased in most venues in 2008, and then increased to some extent in 2010. Voluntary smoking policy is rarely adopted and cannot protect people from SHS

2011-03-01

Relatively few studies have examined gambling problems among individuals in a casino setting. The current study sought to examine the prevalence of gambling problems among a sample of casino patrons and examine alcohol and tobacco use, health status, and quality of life by gambling problem status. To these ends, 176 casino patrons were recruited by going to a Southern California casino and requesting that they complete an anonymous survey. Results indicated the following lifetime rates for at-risk, problem, and pathological gambling: 29.2, 10.7, and 29.8%. Differences were found with regards to gambling behavior, and results indicated higher rates of smoking among individuals with gambling problems, but not higher rates of alcohol use. Self-rated quality of life was lower among pathological gamblers relative to non-problem gamblers, but did not differ from at-risk or problem gamblers. Although subject to some limitations, our data support the notion of higher frequency of gambling problems among casino patrons and may suggest the need for increased interventions for gambling problems on-site at casinos.

SignIn-Stat, a PC-based, menu-driven program, collects information from users of the library's public access computer systems. It was used to collect patron use data for the library's four CD-ROM workstations for the period September 1987 to April 1988 and to survey users for the period December 1987 to March 1988. During the sample period, 5,909 CD-ROM uses were recorded. MEDLINE was the most heavily used database, followed by PsycLIT and Micromedex CCIS. Students accounted for 61% of the use, while faculty, residents, and staff were responsible for 31%. Graduate students had the highest rate of use per student. Nineteen percent of use was by patrons who had never used CD-ROMs before, while 37% was by patrons who had used CD-ROMs ten or more times. Residents were the least experienced user group, while graduate students and faculty were the most experienced. PMID:2203498

Katz, S K; Lavack, A M

2002-03-01

To examine the tobacco industry's use of bar promotions, including their target groups, objectives, strategies, techniques, and results. Over 2000 tobacco industry documents available as a result of the Master Settlement Agreement were reviewed on the internet at several key web sites using keyword searches that included "bar", "night", "pub", "party", and "club". The majority of the documents deal with the US market, with a minor emphasis on Canadian and overseas markets. The documents indicate that bar promotions are important for creating and maintaining brand image, and are generally targeted at a young adult audience. Several measures of the success of these promotions are used, including number of individuals exposed to the promotion, number of promotional items given away, and increased sales of a particular brand during and after the promotion. Bar promotions position cigarettes as being part of a glamorous lifestyle that includes attendance at nightclubs and bars, and appear to be highly successful in increasing sales of particular brands.

Thirty states have smoke-free air laws that ban smoking in restaurants and bars, covering nearly two-thirds of the US population. It is well established that these laws generally have a null or positive economic impact on restaurants and bars. However, all establishments in a geographic area are usually treated as a homogeneous group without considering the potential for differential effects by establishment characteristics. This study uses variation in smoke-free air laws over time to estimate their impact on employment in restaurants and bars with a focus on potential differences by employer size (number of employees). A two-pronged approach with a national-level and state-level analysis is used to take advantage of more granular data availability for a single state (North Carolina). Observational study using panel data. 1) US, 2) North Carolina INTERVENTIONS: Smoke-free air laws. State-level accommodation and food services employment for all 50 states and District of Columbia from 1990 through 2014 (Quarterly Census of Employment and Wages); county-level restaurant and bar employment in North Carolina from 2001 through 2014 (North Carolina Department of Commerce). There is no evidence of a redistributive effect of smoke-free air laws on restaurant and bar employment by employer size. The lack of a redistributive effect is an important finding for policy-makers considering implementation or expansion of a smoke-free air law to protect employees and patrons from the dangers of exposure to secondhand smoke. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

To assess preferences of grocery store patrons concerning pharmacy services and identify study participant characteristics that may predict the success of pharmacy services in the community setting. Self-administered survey. Central Ohio from December 16, 2005, to January 12, 2006. 163 grocery store patrons. Eight grocery store survey events. Responses to survey items about (1) perceived importance of 28 pharmacy services, (2) identification of the 3 most important services, (3) frequency of grocery store and pharmacy use, (4) preferred methods of advertising pharmacy services, and (5) socioeconomic demographics. Preferred services delineated by various demographics also were analyzed. A total of 163 surveys were returned from study participants. Nine services appeared in both the top 12 overall preferred services and the 12 highest-ranked services. Statistically significant differences were observed among services ranked as important or very important by age, race, employment, income, caregiver status, and prescription drug coverage status. The three advertising tools selected most frequently included: weekly grocery store ads (68.6%), in-store signs (51.0%), and flyers attached to prescription bags (36.0%). Grocery store patrons would like a wide range of nontraditional pharmacy services that could be implemented into community pharmacies. Pharmacies in grocery stores need to provide both traditional and expanded pharmacy services to meet the desires and expectations of current and potential patients, and expanded marketing methods should be considered.

Mars by Way of Storytellers and Patrons

NASA Astrophysics Data System (ADS)

Polk, C.

A business model is presented in which space-themed entertainment and educational media are harnessed to the goal of designing and financing the establishment of a self-sustaining Mars outpost. The model draws from two precedents: (i) The National Geographic Society's use of media sales to fund research and (ii) the historical role of patrons in the process of creativity. These precedents are combined in an international non-governmental organization (INGO) that is governed by the individuals who participate in the media businesses branded by the INGO - these individuals constitute a patron base of several tens of millions. Requiring only modest penetration into global media markets, expenditures of USD 5 billion per year (in 2008 dollars) can commence in 2025 and continue at an accelerating rate until the Mars outpost is established. The financing approach utilized, combined with a decision authority that is free to consider a broad range of solutions, will advance the technical state-of-the-art and result in an Earth-Mars infrastructure capable of expanding the initial Mars outpost into humanity's first second home.

[Eligius, the patron of veterinarians].

Saint Eligius became the saint patron of farriers and veterinarians in the 13th century. This was first mentioned by Jordanus Ruffus, emperor Frederic the 2nd's equerry, who refers to a gregorian hymnal dedicated to Eligius. The legend says that Eliguis amputated a horse's foot, shoed it and placed it back on the horse's leg. This legend might have replaced the Germanic cult described in the incantations of Merseburg. In Switzerland the veneration of Eligius is particularly spread in the canton of Lucerne.

Tobacco related bar promotions: insights from tobacco industry documents

PubMed Central

Katz, S; Lavack, A

2002-01-01

Design: Over 2000 tobacco industry documents available as a result of the Master Settlement Agreement were reviewed on the internet at several key web sites using keyword searches that included "bar", "night", "pub", "party", and "club". The majority of the documents deal with the US market, with a minor emphasis on Canadian and overseas markets. Results: The documents indicate that bar promotions are important for creating and maintaining brand image, and are generally targeted at a young adult audience. Several measures of the success of these promotions are used, including number of individuals exposed to the promotion, number of promotional items given away, and increased sales of a particular brand during and after the promotion. Conclusion: Bar promotions position cigarettes as being part of a glamorous lifestyle that includes attendance at nightclubs and bars, and appear to be highly successful in increasing sales of particular brands.

Are Barroom and Neighborhood Characteristics Independently Related to Local-Area Assaults?

PubMed

Morrison, Christopher; Mair, Christina F; Lee, Juliet P; Gruenewald, Paul J

2015-12-01

Two separate but complementary literatures examine bar-related violence: one has focused on barroom features, and the other has focused on features of neighborhoods near bars. This study unifies these 2 perspectives using a microenvironmental approach. In a purposive sample of 65 bars in 4 California cities, we used premise assessments to characterize the physical, social, and economic environments of barrooms (e.g., patron count, average pace of drinking, and restaurant service); and a combination of systematic social observation, census, and alcohol license data to characterize the neighborhoods in which they were located (e.g., physical disorder, alcohol outlet density, and median household income). Hierarchical Poisson models then assessed relationships between these features and counts of police-reported assaults within buffer areas around bars. Aspects of both barroom environments (more patrons, more dancing, and louder music) and neighborhood environments (greater bar density, greater physical disorder, lower population density, and lower income) were independently related to increased incidence of assaults. Preventive intervention to reduce bar-area violence may be directed at both bar environments (e.g., limiting the number of patrons) and neighborhood environments (e.g., limiting outlet density).

Research on new casinos typically focuses upon their impact on the community, rather than on specific at-risk groups. This research study explores the impact of the opening of a new casino on attitudes of older adult casino patrons, especially those at particular risk of having gambling problems. Results demonstrate that over 80% of older adult casino patrons would not change their attitudes toward gambling or expect to increase their gambling as a result of the opening of a new casino. However, older adults with problem gambling issues are more likely to indicate they would visit a casino more, spend more time at a casino, and gamble more as a result of the opening of a new casino. In addition, older adults with signs of a gambling problem are more likely to say the opening of a new casino would change their opinions of gambling in general or casino gambling.

This large outbreak of foodborne disease highlights the challenge of investigating outbreaks caused by intentional contamination and demonstrates the vulnerability of self-service foods to intentional contamination. To investigate a large community outbreak of Salmonella Typhimurium infections. Epidemiologic investigation of patients with Salmonella gastroenteritis and possible exposures in The Dalles, Oregon. Cohort and case-control investigations were conducted among groups of restaurant patrons and employees to identify exposures associated with illness. A community in Oregon. Outbreak period was September and October 1984. A total of 751 persons with Salmonella gastroenteritis associated with eating or working at area restaurants. Most patients were identified through passive surveillance; active surveillance was conducted for selected groups. A case was defined either by clinical criteria or by a stool culture yielding S Typhimurium. The outbreak occurred in 2 waves, September 9 through 18 and September 19 through October 10. Most cases were associated with 10 restaurants, and epidemiologic studies of customers at 4 restaurants and of employees at all 10 restaurants implicated eating from salad bars as the major risk factor for infection. Eight (80%) of 10 affected restaurants compared with only 3 (11%) of the 28 other restaurants in The Dalles operated salad bars (relative risk, 7.5; 95% confidence interval, 2.4-22.7; P<.001). The implicated food items on the salad bars differed from one restaurant to another. The investigation did not identify any water supply, food item, supplier, or distributor common to all affected restaurants, nor were employees exposed to any single common source. In some instances, infected employees may have contributed to the spread of illness by inadvertently contaminating foods. However, no evidence was found linking ill employees to initiation of the outbreak. Errors in food rotation and inadequate refrigeration on ice

The pterygospinous ligament extends from the posterior free margin of the lateral pterygoid plate till the spine of the sphenoid. The ligament may ossify partly or completely leading to the formation of the pterygospinous bar. A complete ossification of the ligament results in the formation of the foramen of Civinini. Presence of the complete or incomplete pterygospinous bar may lead to a difficulty in passing the needle during anaesthesia for the trigeminal neuralgia or the bar may also compress the mandibular nerve and its branches to cause lingual numbness, pain and speech impairment. Presence of the complete or incomplete pterygospinous bar and the foramen of Civinini were studied in 55 dried adult skulls and 20 sphenoid bones. Partial or complete ossification of the pterygospinous ligament was seen in 17.33 % skulls. One skull showed the presence of bilateral complete pterygospinous bar while another skull had the unilateral complete pterygospinous bar on right side. Two skulls and one sphenoid had bilateral incomplete pterygospinous bar while seven skulls and one sphenoid bone had unilateral incomplete pterygospinous bar. In three cases, the bar was passing just below the foramen ovale. The pterygospinous bar when present medial to the foramen ovale may not have much clinical significance but when the bar is present just below the foramen ovale, it may cause a compression of the mandibular nerve and its branches and may also obstruct the passage for the transoval approach to the neighbouring regions.

TORCH is a large-area precision time-of-flight detector based on the DIRC principle. The DIRC bar boxes of the BaBar experiment at SLAC could possibly be reused to form a part of the TORCH detector time-of-flight wall area, proposed to provide positive particle identification of low momentum kaons in the LHCb experiment at CERN. For a potential integration of BaBar bar boxes into TORCH, new imaging readout optics are required. From the several designs of readout optics that have been considered, two are used in this paper to study the effect of BaBar bar optical imperfections on the detector reconstruction performance. The kaon-pion separation powers obtained from analysing simulated photon hit patterns show the performance reduction for a BaBar bar of non-square geometry compared to a perfectly rectangular cross section.

The observation of B -> τ \\bar {μ } + μ \\bar {τ } at present experiments would be a clear sign of new physics. In this paper, we calculate this process in an extended Higgs sector framework where the decay is mediated by the exchange of spin zero particle with flavor changing neutral current couplings. If we identify the scalar with the newly discovered state at LHC with a mass 125 GeV then we find that, after imposing all experimental constraints, the BR(Bs -> τ \\bar {μ } + μ \\bar {τ }) can be as high as 10-6 and BR (Bd -> τ \\bar {μ } + μ \\bar {τ }) can be as high as 10-7. We also calculate this process in the minimal supersymmetric standard model and find the BR(Bs ->τ \\bar {μ } + μ \\bar {τ }) is typically of the order 10-8.

We make use of the voluntary HIV and syphilis test results conducted at five gay saunas in Taipei from August of 1999 to end of 2002 to estimate the number of HIV-positive gay saunas patrons in Taipei area by utilizing Hierarchical Bayes method in Generalized Removal Model for Open Populations (GERMO). Considering the effect of a nearby anonymous HIV quick test program on the gay sauna HIV serotesting data, we make use of the association between HIV and syphilis serotesting results from the gay sauna program to amend possible measurement error occurred at the time of data collection by utilizing the regression calibration method. The median estimates for the number of HIV-positive patrons of the five gay saunas increase from 120 (95% CI: 76.5-159.0) during the first half of 2000 to 224 (95% CI: 171.0-265.5) for the second half of 2002. The result, indicating two-fold increase within two and half years, confirms that the gay sauna patrons in Taipei area are at high risk for HIV infection.

Adherence to the Tobacco Control Act, 2007: presence of a workplace policy on tobacco use in bars and restaurants in Nairobi, Kenya

PubMed Central

Karimi, K J; Ayah, R; Olewe, T

2016-01-01

Introduction Despite extensive knowledge about effective tobacco control interventions, the prevalence of tobacco use in many middle- and low-income countries continues to rise. In these countries, public appreciation of levels of protection provided by laws and regulations on tobacco use and exposure to tobacco smoke is limited. After ratification of the Framework Convention on Tobacco Control, Kenya enacted the Tobacco Control Act, 2007, banning smoking in public places except in designated smoking areas. Objective To assess adherence to the Tobacco Control Act, 2007 by determining the presence of a workplace policy on tobacco use in bars and restaurants. Methods A survey of 176 liquor licensed bars and restaurants in Nairobi County was carried out. Their managers were asked about the presence of a workplace policy governing smoking of tobacco, and observations made on provisions that determine adherence to the Tobacco Control Act, 2007. Results Smoking took place in almost all bars and restaurants (150 (85%)). Half the establishments (86 (49%)) had a workplace policy governing tobacco use among employees, although a difference between bars (11 (23%)) and restaurants (75 (58%)) was recorded (p<0.001). Establishments at which managers had lower levels of education were less likely to have a workplace policy (p<0.001) and less likely to have ‘no smoking’ signs and designated smoking areas (p<0.005). Conclusions and recommendations Kenya's implementation of the Tobacco Control Act, 2007 does not provide sufficient protection of patrons and workers in bars and restaurants. It is important to sensitise hospitality workers to the dangers of tobacco smoke. Bar and restaurants managers should have a minimum post-secondary education level. The Tobacco Control Act, 2007 requires strengthening to ensure that bars and restaurants have a smoke-free environment. PMID:27683518

Nightclubs are favorable environments for alcohol abuse and the use of other drugs among patrons. To identify patterns of alcohol use in a high-risk population and their relationship with sociodemographic factors and illicit drug use. A portal survey technique was used to recruit patrons in 31 nightclubs in the city of São Paulo, Brazil. A two stage sampling method allowed the selection of nightclubs and patrons within a nightclub. A total of 1057 patrons answered to a three stages-survey (nightclub entrance and exit face-to-face interviews and a day-after online questionnaire). Entrance survey offered information on sociodemographic data and history of drug use. The day-after survey used the Alcohol Use Disorders Identifications Test (AUDIT) that identified patterns of alcohol abuse disorders. Data were modeled using an ordered logit regression analysis, considering sample weights. Almost half of the nightclub patrons presented any alcohol use disorder (AUDIT score ≥8). Being male (OR = 1.68; 95% CI = 1.09-2.60) and single (OR = 1.71; 95% CI = 1.05-2.76) increased the chances for more severe alcohol use disorders. Having a graduate degree (OR = 0.57; 95% CI = 0.38-0.87) and age ≥35 years (OR = 0.48; 95% CI = 0.27-0.85) decreased the chances of patrons' alcohol use disorders. The prevalence rates of past-year marijuana, cocaine and inhalants use increased with the increased level of alcohol use disorders. Patrons of nightclubs show higher prevalence rates for any alcohol use disorders than the general population. Patrons could benefit from governmental brief intervention or referral to treatment for alcohol used disorders disclosed in nightclubs.

Social Branding to Decrease Lesbian, Gay, Bisexual, and Transgender Young Adult Smoking

Fallin, Amanda; Neilands, Torsten B.; Jordan, Jeffrey W.

2015-01-01

Introduction: Lesbian, gay, bisexual, and transgender (LGBT) individuals are more likely to smoke than the general population. This study evaluated a Social Branding intervention, CRUSH, which included an aspirational brand, social events, and targeted media to discourage smoking among LGBT young adults in Las Vegas, NV. Methods: Cross-sectional surveys (N = 2,395) were collected in Las Vegas LGBT bars at 2 time points 1 year apart. Multivariate logistic regressions examined associations between campaign exposure, message understanding, and current (past 30 days) smoking, controlling for demographics. Results: LGBT individuals were significantly more likely to report current (past 30 day) smoking than heterosexual/straight, gender-conforming participants. Overall, 53% of respondents reported exposure to CRUSH; of those exposed, 60% liked the campaign, 60.3% reported they would attend a CRUSH event on a night when they usually went somewhere else, and 86.3% correctly identified that the campaign was about “partying fresh and smokefree.” Current smoking was reported by 47% of respondents at Time 1 and 39.6% at Time 2. There were significant interactions between time and campaign exposure and campaign exposure and understanding the message. Among those who understood the CRUSH smokefree message, the highest level of campaign exposure was significantly associated with 37%–48% lower odds for current smoking. Conclusions: While longitudinal studies would better assess the impact of this intervention, CRUSH shows promise to reduce tobacco use among LGBT bar patrons. PMID:26180223

Background This study compares the sexual behavior and HIV prevalence of men and women at social venues where people meet new sexual partners in Eastern Kinshasa with the HIV prevalence and behavior of STI treatment and antenatal clinic patients in the same area. Methods ANC clinic patients, STI clinic patients and social venue patrons were interviewed, asked to provide a blood sample onsite, and provided information about obtaining test results. All social venue patrons at all identified social venues in the study area were invited to participate. Results 1,116 pregnant women; 66 male and 229 female STI clinic patients; and 952 male and 247 female patrons of social venues were interviewed and tested. HIV prevalence ranged by group: ANC patients (4%); female venue patrons (12%); female STI patients (16%); male venue patrons (2%); and male STI patients (23%). HIV prevalence among sexworkers at social venues (29%) was higher than the prevalence among other female patrons with new or multiple partnerships (19%) or among female patrons denying sexwork (6%). However, the absolute number of infected women was higher among women reporting recent new or multiple partnerships than the smaller group of sexworkers (23 vs 18). Two-thirds of the infected female STI patients (24/36) reported no more than one sexual partner in the past year. Conclusion Improving prevention programs in Kinshasa is essential. Prevention efforts should not neglect women at social venues who do not self-identify as sexworkers but have high rates of new sexual partnerships. PMID:19525891

Gaseous Structures in Barred Galaxies: Effects of the Bar Strength

NASA Astrophysics Data System (ADS)

Kim, Woong-Tae; Seo, Woo-Young; Kim, Yonghwi

2012-10-01

Using hydrodynamic simulations, we investigate the physical properties of gaseous substructures in barred galaxies and their relationships with the bar strength. The gaseous medium is assumed to be isothermal and unmagnetized. The bar potential is modeled as a Ferrers prolate with index n. To explore situations with differing bar strength, we vary the bar mass f bar relative to the spheroidal component as well as its aspect ratio { R}. We derive expressions as functions of f bar and { R} for the bar strength Qb and the radius r(Qb ) where the maximum bar torque occurs. When applied to observations, these expressions suggest that bars in real galaxies are most likely to have f bar ~ 0.25-0.50 and n <~ 1. Dust lanes approximately follow one of the x 1-orbits and tend to be straighter under a stronger and more elongated bar, but are insensitive to the presence of self-gravity. A nuclear ring of a conventional x 2 type forms only when the bar is not so massive or elongated. The radius of an x 2-type ring is generally smaller than the inner Lindblad resonance, decreases systematically with increasing Qb , and is slightly larger when self-gravity is included. This is evidence that the ring position is not determined by the resonance, but instead by the amount of angular momentum loss at dust-lane shocks. Nuclear spirals exist only when the ring is of the x 2 type and is sufficiently large in size. Unlike the other features, nuclear spirals are transient in that they start out being tightly wound and weak, and then, due to the nonlinear effect, unwind and become stronger until they turn into shocks, with an unwinding rate that is higher for larger Qb . The mass inflow rate to the galaxy center is found to be less than 0.01 M ⊙ yr-1 for models with Qb <~ 0.2, while becoming larger than 0.1 M ⊙ yr-1 when Qb >~ 0.2 and self-gravity is included.

To compare the effect of an experimental viscous fiber (VF) crispy bar on the postprandial glucose, insulin, and C-peptide response in adult subjects with type 2 diabetes to two commercially available control crispy bars. The study was a randomized, double-blinded, three period, crossover study. The study was conducted at two sites: Park Nicollet Institute, International Diabetes Center, Minneapolis, MN, and Radiant Research, Inc., Minneapolis, MN. A total of 60 adults with type 2 diabetes taking oral antihyperglycemic medication participated in the study. After an overnight fast, subjects consumed a test meal containing an equicaloric amount (300 kcal) of an experimental VF crispy bar or one of two commercially available crispy bars at each of three test visits, followed by a four hour meal tolerance test. Subjects also completed gastrointestinal (GI) response records for the 24 hours following each test visit. The VF crispy bars produced significantly lower glucose (p < 0.0001), insulin (p < 0.0001), and C-peptide (p < 0.0001) responses (as measured by positive area under the curve) in subjects with type 2 diabetes, as compared with the two commercially available bars. Intensity (p < 0.05) and frequency (p < 0.05) of flatulence were significantly higher with the VF bar as compared with the 2 commercial bars. While the VF bar produced significant subjective GI tolerance scoring values, the mean value was below 3 on a scale of 0 (no effect) to 10 (most severe effect) for all tested materials. The incorporation of VF into a crispy bar provided a means to improve blood glucose levels by reducing postprandial glucose, insulin, and C-peptide responses in subjects with type 2 diabetes. Though associated with some GI symptoms, VF may have application in improving the postprandial glycemic response in people with diabetes attempting intensive glucose control.

The effect of the grab bar on dynamic stability when elderly people enter the bathtub remains unclear. The purpose of the present study is to examine the age-related effect of the grab bar on dynamic stability during lateral stepping over an obstacle when entering bathtub. Sixteen young, healthy adults and sixteen elderly adults participated. The subjects performed lateral stepping over an obstacle with and without vertical and horizontal bars. Displacement and velocity of the center of mass and utilized friction, which is the required coefficient of friction to avoid slipping, were simultaneously measured by a three-dimensional motion analysis system and two force plates. A post hoc test for two-way ANOVA revealed that velocity of the center of mass in the vertical direction (p<0.05) and peak-to-peak values of the center of mass in the lateral (p<0.05) and vertical directions (p<0.05) with each grab bar were significantly slower and smaller than those without the grab bar in young and elderly people. Moreover, the utilized friction at push off of the trailing leg with the vertical bar in elderly people was lower (p<0.05) than that in participants without the grab bar. The use of each grab bar while performing a lateral step over an obstacle may help maintaining balance in lateral and vertical directions. However, use of the vertical bar while lateral stepping over an object in elderly people may need low utilized friction to prevent slipping. Copyright © 2017 Elsevier Ltd. All rights reserved.

Effects of the Bar Strength of Gaseous Features in Barred Galaxies

2013-01-01

Barred galaxies commonly possess gaseous structures such as a pair of dust lanes, a nuclear ring, and nuclear spirals at their centers. We use hydrodynamic simulations to study the physical properties of the gaseous structures in barred galaxies and their relationships with the bar strength. We vary the bar mass fbar relative to the spheroidal component as well as its aspect ratio. We derive expressions for the bar strength Qb and the radius where the maximum bar torque occurs. When applied to observations, these expressions suggest that bars in real galaxies are most likely to have fbar = 0.25-0.5. Dust lanes approximately follow one of x1-orbits and tend to be more straight under a stronger and more elongated bar. A nuclear ring of a conventional x2 type forms only when the bar is not so massive or elongated. The radius of an x2-type ring is generally smaller than the inner Lindblad resonance, decreases systematically with increasing Qb, evidencing that the ring position is not determined by the resonance but by the bar strength. Nuclear spirals exist only when the ring is of the x2-type and sufficiently large in size. Unlike the other features, nuclear spirals are transient in that they start out as being tightly-wound and weak, and then due to the nonlinear effect unwind and become stronger until turning into shocks, with an unwinding rate higher for larger Qb. These results suggest that the bar strength is the primary factor that determine the properties of gaseous structures in barred galaxies.

Gay bathhouse HIV prevention: the use of staff monitoring of patron sexual behavior.

Many HIV prevention interventions have been launched in gay bathhouses and sex clubs since the onset of the AIDS epidemic, such as condom distribution and HIV testing. Perhaps none of these are as intrusive to the venue's environment as what is called "monitoring," which involves staff, during every shift, repeatedly walking throughout the public areas of a bathhouse to check on patrons' sexual behavior. Yet, monitoring has received little evaluation. Between 2002 and 2004, we conducted qualitative interviews with venue managers, staff and patrons in New York City, Los Angeles, and the San Francisco Bay Area. An analysis found that monitoring was influenced by the kinds of space available for sex, suggesting three approaches to monitoring: 1) monitoring all sex in clubs that only had public areas where men had sex ; 2) monitoring some sex in clubs with private rooms for sex; and 3) no monitoring of sex, regardless of the kinds of space for sex. This paper explores each approach as described by club managers, staff, and patrons to understand the potential effectiveness of monitoring as an HIV prevention intervention.

Pectus bar removal is the final stage of the procedure for minimally invasive repair of pectus excavatum. Based on our experience with one of the largest scale data, we would like to address the important issues in pectus bar removal, such as appropriate duration of bar maintenance, techniques for bar removal, and strategies to avoid complications. Between September 1999 and August 2015, we operated on 2,553 patients with pectus excavatum and carinatum using pectus bars for a minimally invasive approach. Among them, 1,821 patients (71.3%) underwent pectus bar removal as a final stage of pectus deformity repair, and their data were analyzed retrospectively to identify the outcomes and adverse effects of the pectus bar removal procedure. The mean age of the patients was 9.13 years (range, 16 months to 44 years) and the male to female ratio was 3.55. The study is approved by the Institutional Review Board (IRB), the ethical committee of Seoul St. Mary's Hospital. The IRB has exempted the informed consent from every patient in this study due to this is a retrospective chart review without revealing any patients' personal data. Our technique involved straightening of the bar in a supine position. The overall mean duration of pectus bar maintenance was 2.57 years (range, 4 months to 14 years). The mean duration was 2.02 years (range, 4 months to 7 years) for children under 12 years, 2.99 years (range, 7 months to 9 years) for teenagers aged 12-20 years, and 3.53 years (range, 3 months to 14 years) for adults over 20 years. Forty-eight patients (2.6%) underwent bar removal more than 5 years after bar insertion and 58 patients (3.2%) underwent bar removal earlier than initially planned. The most common adverse reaction after bar removal was wound seroma including infection (43 patients, 2.36%). Recurrence after bar removal occurred in nine patients (0.49%), and seven of these required redo repair (0.38%). Pectus bar removal is a safe and straightforward procedure with a

Reference departments track patron interactions to illustrate the type and number of services provided as well as to tailor librarians' time and expertise to the interest and needs of their patrons. Until 2010 the Reference, Education, and Community Engagement Department at the Calder Memorial Library tracked statistics using a complicated system of paper tic sheets and two Excel™ spreadsheets. After considering different electronic systems, the department decided to employ an electronic form created with SurveyMonkey™ to track patron interactions. After the system had been in place for three months, the authors administered a satisfaction and use survey to collect faculty and staff feedback on the new system. Seven months later the authors undertook usability testing to collect further evaluative data on the electronic form. The patron interaction form continues to be used to collect statistics, provide data for annual reviews, and recognize the contributions of all faculty and staff at the library.

Disentangling contributions of bar attendance, drinking, and other factors to elevated acute alcohol problems on the U.S.-Mexico border.

Levels of drinking are unusually elevated among young adults on the U.S.-Mexico border, and this elevation can be largely explained by young border residents' unusually high frequency of bar attendance. However, this explanation complicates interpretation of high alcohol problem rates that have also been observed in this group. Because bar environments can lower the threshold for many types of problems, the extent to which elevated alcohol problems among young border residents can be attributed to drinking per se-versus this common drinking context-is not clear. Data were collected from multistage cluster samples of adult Mexican Americans on and off the U.S.-Mexico border (current drinker N = 1,351). After developing structural models of acute alcohol problems, estimates were subjected to path decompositions to disentangle the common and distinct contributions of drinking and bar attendance to problem disparities on and off the border. Additionally, models were estimated under varying degrees of adjustment to gauge the sensitivity of the results to sociodemographic, social-cognitive, and environmental sources of confounding. Consistent with previous findings for both drinking and other problem measures, acute alcohol problems were particularly elevated among young adults on the border. This elevation was entirely explained by a single common pathway involving bar attendance frequency and drinking. Bar attendance did not predict acute alcohol problems independently of drinking, and its effect was not moderated by border proximity or age. The common indirect effect and its component effects (of border youth on bar attendance, of bar attendance on drinking, and of drinking on problems) were surprisingly robust to adjustment for confounding in all parts of the model (e.g., fully adjusted indirect effect: b = 0.11, SE = 0.04, p < 0.01). Bar attendance and associated increases in drinking play a key, unique role in the high levels of acute alcohol problems among the

Adherence to the Tobacco Control Act, 2007: presence of a workplace policy on tobacco use in bars and restaurants in Nairobi, Kenya.

PubMed

Karimi, K J; Ayah, R; Olewe, T

2016-09-28

Despite extensive knowledge about effective tobacco control interventions, the prevalence of tobacco use in many middle- and low-income countries continues to rise. In these countries, public appreciation of levels of protection provided by laws and regulations on tobacco use and exposure to tobacco smoke is limited. After ratification of the Framework Convention on Tobacco Control, Kenya enacted the Tobacco Control Act, 2007, banning smoking in public places except in designated smoking areas. To assess adherence to the Tobacco Control Act, 2007 by determining the presence of a workplace policy on tobacco use in bars and restaurants. A survey of 176 liquor licensed bars and restaurants in Nairobi County was carried out. Their managers were asked about the presence of a workplace policy governing smoking of tobacco, and observations made on provisions that determine adherence to the Tobacco Control Act, 2007. Smoking took place in almost all bars and restaurants (150 (85%)). Half the establishments (86 (49%)) had a workplace policy governing tobacco use among employees, although a difference between bars (11 (23%)) and restaurants (75 (58%)) was recorded (p<0.001). Establishments at which managers had lower levels of education were less likely to have a workplace policy (p<0.001) and less likely to have 'no smoking' signs and designated smoking areas (p<0.005). Kenya's implementation of the Tobacco Control Act, 2007 does not provide sufficient protection of patrons and workers in bars and restaurants. It is important to sensitise hospitality workers to the dangers of tobacco smoke. Bar and restaurants managers should have a minimum post-secondary education level. The Tobacco Control Act, 2007 requires strengthening to ensure that bars and restaurants have a smoke-free environment. Published by the BMJ Publishing Group Limited.

The Carnegie-Irvine Galaxy Survey. V. Statistical Study of Bars and Buckled Bars

Li, Zhao-Yu; Ho, Luis C.; Barth, Aaron J.

2017-08-01

Simulations have shown that bars are subject to a vertical buckling instability that transforms thin bars into boxy or peanut-shaped structures, but the physical conditions necessary for buckling to occur are not fully understood. We use the large sample of local disk galaxies in the Carnegie-Irvine Galaxy Survey to examine the incidence of bars and buckled bars across the Hubble sequence. Depending on the disk inclination angle (I), a buckled bar reveals itself as either a boxy/peanut-shaped bulge (at high I) or as a barlens structure (at low I). We visually identify bars, boxy/peanut-shaped bulges, and barlenses, and examine the dependence of bar and buckled bar fractions on host galaxy properties, including Hubble type, stellar mass, color, and gas mass fraction. We find that the barred and unbarred disks show similar distributions in these physical parameters. The bar fraction is higher (70%-80%) in late-type disks with low stellar mass (M * < 1010.5 M ⊙) and high gas mass ratio. In contrast, the buckled bar fraction increases to 80% toward massive and early-type disks (M * > 1010.5 M ⊙), and decreases with higher gas mass ratio. These results suggest that bars are more difficult to grow in massive disks that are dynamically hotter than low-mass disks. However, once a bar forms, it can easily buckle in the massive disks, where a deeper potential can sustain the vertical resonant orbits. We also find a probable buckling bar candidate (ESO 506-G004) that could provide further clues to understand the timescale of the buckling process.

Cult of St. Blasius, patron saint of throat sufferers and of otolaryngologists, in Croatia.

In the introductory part presented is a short hagiography of St. Blasius, and the legend of miraculous healing of a child in whose throat a bone had stuck, threatening to choke the child. Thanks to that legend, St. Blasius has become the traditional patron of the laryngeal diseases, and, since recently, the patron of the otolaryngologists, too. The second part of the paper is dedicated to the cult of St. Blasius, which is present in Croatia since the 10th century until present. Venerated all over the country, St. Blasius has been "elected" the heavenly protector of 10 parish communities, as well as of the city and the dioceses of Dubrovnik. Beside pilgrimage and prayers, among many traditional forms of folk piety, a ritual called "grlicenje" has been preserved-a curative and preventive blessing of the throat with crossed candles on the Saint's Day. In more recent times, the same day has been remembered among Croatian otolaryngologists and the societies of laryngectomized persons, who chose St. Blasius for their patron, too.

OBJECTIVES: This study assessed the potential effect of smoke-free policies on bar and restaurant patronage. METHODS: Random-digit dialing techniques were used in surveying a representative sample of Massachusetts adults (n = 2356) by telephone. RESULTS: Approximately 61% of the respondents predicted no change in their use of restaurants in response to smoke-free policies, 30% predicted increased use, and 8% predicted decreased use. In turn, 69% of the respondents predicted no change in their patronage of bars, while 20% predicted increased use and 11% predicted decreased use. CONCLUSIONS: These results suggest that smoke-free policies are likely to increase overall patronage of bars and restaurants. PMID:9431301

Wreaking "havoc" on smoking: social branding to reach young adult "partiers" in Oklahoma.

More than 25% of young adult Oklahomans smoked cigarettes in 2012. Tobacco marketing campaigns target young adults in social environments like bars/nightclubs. Social Branding interventions are designed to compete directly with this marketing. To evaluate an intervention to reduce smoking among young adult "Partiers" in Oklahoma. The Partier peer crowd was described as follows: attendance at large nightclubs, fashion consciousness, valuing physical attractiveness, and achieving social status by exuding an image of confidence and financial success. Repeated cross-sectional study with three time points. Randomized time location survey samples of young adult Partier bar and club patrons in Oklahoma City (Time 1 [2010], n=1,383; Time 2 [2011], n=1,292; and Time 3 [2012], n=1,198). Data were analyzed in 2013. The "HAVOC" Social Branding intervention was designed to associate a smoke-free lifestyle with Partiers' values, and included events at popular clubs, brand ambassador peer leaders who transmit the anti-tobacco message, social media, and tailored anti-tobacco messaging. Daily and nondaily smoking rates, and binge drinking rates (secondary). Overall, smoking rates did not change (44.1% at Time 1, 45.0% at Time 2, and 47.4% at Time 3; p=0.17), but there was a significant interaction between intervention duration and brand recall. Partiers reporting intervention recall had lower odds of daily smoking (OR=0.30 [0.10, 0.95]) and no difference in nondaily smoking, whereas Partiers who did not recall the intervention had increased odds of smoking (daily AOR=1.74 [1.04, 2.89]; nondaily AOR=1.97 [1.35, 2.87]). Among non-Partiers, those who recalled HAVOC reported no difference in smoking, and those who did not recall HAVOC reported significantly increased odds of smoking (daily AOR=1.53 [1.02, 2.31]; nondaily AOR=1.72 [1.26, 2.36]). Binge drinking rates were significantly lower (AOR=0.73 [0.59, 0.89]) overall. HAVOC has the potential to affect smoking behavior among

Bar Evolution and Bar Properties from Disc Galaxies in the Early Universe

NASA Astrophysics Data System (ADS)

Hutchinson-Smith, Tenley; Simmons, Brooke

2017-01-01

Bars in disc galaxies indicate a large collection of stars in a specific configuration of orbits that give the galaxy center a rectangular looking feature. Astronomers have discovered that these bars affect the distribution of matter in galaxies, and are also related to galaxy stellar mass and star formation history. Little is known about the specifics of how bars evolve and drive the evolution of their host galaxies because only a handful of bars have been studied in detail so far. I have examined a sample of 8,221 barred galaxies from the early universe to identify and examine correlations with galaxy properties. The data comes from Galaxy Zoo, an online citizen science project that allows anyone to classify and measure detailed properties of galaxies. I present results including the fraction of galaxies in the sample that have bars, and the variation of galaxy properties with bar length, including galaxy color and stellar mass. I also compare these results to barred galaxies in the local universe. I will discuss the implications of these results in the context of galaxy evolution overall, including the effect of dark matter on bars and galaxy evolution.

The dual function of barred plumage in birds: camouflage and communication.

PubMed

Gluckman, T L; Cardoso, G C

2010-11-01

A commonly held principle in visual ecology is that communication compromises camouflage: while visual signals are often conspicuous, camouflage provides concealment. However, some traits may have evolved for communication and camouflage simultaneously, thereby overcoming this functional compromise. Visual patterns generally provide camouflage, but it was suggested that a particular type of visual pattern – avian barred plumage – could also be a signal of individual quality. Here, we test if the evolution of sexual dimorphism in barred plumage, as well as differences between juvenile and adult plumage, indicate camouflage and/or signalling functions across the class Aves. We found a higher frequency of female- rather than male-biased sexual dimorphism in barred plumage, indicating that camouflage is its most common function. But we also found that, compared to other pigmentation patterns, barred plumage is more frequently biased towards males and its expression more frequently restricted to adulthood, suggesting that barred plumage often evolves or is maintained as a sexual communication signal. This illustrates how visual traits can accommodate the apparently incompatible functions of camouflage and communication, which has implications for our understanding of avian visual ecology and sexual ornamentation.

Social Branding to Decrease Lesbian, Gay, Bisexual, and Transgender Young Adult Smoking.

Lesbian, gay, bisexual, and transgender (LGBT) individuals are more likely to smoke than the general population. This study evaluated a Social Branding intervention, CRUSH, which included an aspirational brand, social events, and targeted media to discourage smoking among LGBT young adults in Las Vegas, NV. Cross-sectional surveys (N = 2,395) were collected in Las Vegas LGBT bars at 2 time points 1 year apart. Multivariate logistic regressions examined associations between campaign exposure, message understanding, and current (past 30 days) smoking, controlling for demographics. LGBT individuals were significantly more likely to report current (past 30 day) smoking than heterosexual/straight, gender-conforming participants. Overall, 53% of respondents reported exposure to CRUSH; of those exposed, 60% liked the campaign, 60.3% reported they would attend a CRUSH event on a night when they usually went somewhere else, and 86.3% correctly identified that the campaign was about "partying fresh and smokefree." Current smoking was reported by 47% of respondents at Time 1 and 39.6% at Time 2. There were significant interactions between time and campaign exposure and campaign exposure and understanding the message. Among those who understood the CRUSH smokefree message, the highest level of campaign exposure was significantly associated with 37%-48% lower odds for current smoking. While longitudinal studies would better assess the impact of this intervention, CRUSH shows promise to reduce tobacco use among LGBT bar patrons. © The Author 2015.

Recently, the Belle collaboration reported the first measurement of the τ lepton polarization P τ (D*) in \\bar{B}\\to {D}* {τ }-{\\bar{ν }}τ decay and a new measurement of the rate of the branching ratios R(D*), which are consistent with the Standard Model (SM) predictions. These could be used to constrain the New Physics (NP) beyond the SM. In this paper, we probe \\bar{B}\\to {D}(* ){{\\ell }}-{\\bar{ν }}{\\ell } (ℓ = e, μ, τ) decays in the model-independent way and in the specific G(221) models with lepton flavour universality. Considering the theoretical uncertainties and the experimental errors at the 95% C.L., we obtain the quite strong bounds on the model-independent parameters {C}{{LL}}{\\prime },{C}{{LR}}{\\prime },{C}{{RR}}{\\prime },{C}{{RL}}{\\prime },{g}V,{g}A,{g}V{\\prime },{g}A{\\prime } and the specific G(221) model parameter rates. We find that the constrained NP couplings have no obvious effects on all (differential) branching ratios and their rates, nevertheless, many NP couplings have very large effects on the lepton spin asymmetries of \\bar{B}\\to {D}(* ){{\\ell }}-{\\bar{ν }}{\\ell } decays and the forward–backward asymmetries of \\bar{B}\\to {D}* {{\\ell }}-{\\bar{ν }}{\\ell }. So we expect precision measurements of these observables would be researched by LHCb and Belle-II.

Do pharmacy staff recommend evidenced-based smoking cessation products? A pseudo patron study.

Chiang, P P C; Chapman, S

2006-06-01

To determine whether pharmacy staff recommend evidence-based smoking cessation aids. Pseudo patron visit to 50 randomly selected Sydney pharmacies where the pseudo patron enquired about the 'best' way to quit smoking and about the efficacy of a non-evidence-based cessation product, NicoBloc. Nicotine replacement therapy was universally stocked and the first product recommended by 90% of pharmacies. After prompting, 60% of pharmacies, either also recommended NicoBloc or deferred to 'customer choice'. About 34% disparaged the product. Evidence-based smoking cessation advice in Sydney pharmacies is fragile and may be compromised by commercial concerns. Smokers should be provided with independent point-of-sale summaries of evidence of cessation product effectiveness and warned about unsubstantiated claims.

Comparison of near fusional vergence ranges with rotary prisms and with prism bars.

2011-02-01

Common methods for determination of fusional vergence ranges make use of rotary prisms in the phoropter or prism bars out of the phoropter. This study compared near fusional vergence ranges with rotary prisms with those with prism bars. Fifty young adults served as subjects. Odd-numbered subjects had rotary prism vergences performed before prism bar vergences. For even-numbered subjects, prism bar vergences were done first. Base-in (BI) vergences were done before base-out (BO) vergences with both rotary prisms and prism bars. A coefficient of agreement was calculated by multiplying the standard deviation of the individual subject differences between rotary prisms and prism bars by 1.96, to approximate the range within which the 2 tests would agree 95% of the time. The lowest coefficient of agreement was 7.3Δ for the BI recovery. The others were high, ranging from 15.4Δ for the BO recovery to 19.5Δ for the BO break. Fusional vergence ranges determined by prism bars out of the phoropter cannot be used interchangeably with those determined by phoropter rotary prisms for the purpose of follow-up on individual patients or for the purpose of comparison with norms.

To compare the complications associated with age and technique groups in patients undergoing pectus excavatum (PE) repair. The data of 994 patients who underwent PE repair from March 2011 to December 2015 were retrospectively reviewed. Mean age was 9.59 years (range 31 months-55 years), and 756 patients were men (76.1%). The age groups were defined as follows: Group 1, <5 years; Group 2, 5-9 years; Group 3, 10-14 years; Group 4, 15-17 years; Group 5, 18-19 years; Group 6, 20-24 years; and Group 7, >24 years. The technique groups were defined as follows: Group 1, patients who underwent repair with claw fixators and hinge plates; Group 2, patients who underwent repair with our 'bridge' technique. Complications were compared between age groups and technique groups. No cases of mortality occurred. Complication rates in the age groups 1-7 were 5.4%, 3.6%, 12.1%, 18.2%, 17.3%, 13.9% and 16.7%, respectively. The complication rate tripled after the age of 10. In multivariable analysis, odds ratio of Groups 4, 5 and 7 and asymmetric types were 3.04, 2.81, 2.97 and 1.70 (P < 0.01, P = 0.02, 0.03 and 0.03, respectively). The bar dislocation rate in technique Group 1 was 0.8% (6 of 780). No bar dislocations occurred in technique Group 2. Older patients have more asymmetric pectus deformity and they are also risk factors for complications following PE repair. The bridge technique provides a bar dislocation rate of 0%, even in adult patients. This procedure seems to reduce or prevent major complications following PE repair. © The Author 2017.

ABC labels are made in a company-developed anodizing aluminum process and consecutively marketed with bar code symbology and human readable numbers. They offer extreme abrasion resistance and indefinite resistance to ultraviolet radiation, capable of withstanding 700 degree temperatures without deterioration and up to 1400 degrees with special designs. They offer high resistance to salt spray, cleaning fluids and mild acids. ABC is now producing these bar code labels commercially or industrial customers who also need labels to resist harsh environments.

Pectus bar rotation is a major challenge in pectus repair. However, to date, no satisfactory technique to completely eliminate bar displacement has been introduced. Here, we propose a bar fixation technique using a bridge that makes the bar unmovable. The purpose of this study was to determine the efficacy of this bridge technique. A total of 80 patients underwent pectus bar repair of pectus excavatum with the bridge technique from July 2013 to July 2014. The technique involved connecting 2 parallel bars using plate-screws at the ends of the bars. To determine bar position change, the angles between the sternum and pectus bars were measured on postoperative day 5 (POD5) and 4 months (POM4) and compared. The mean patient age was 17.5 years (range, 6-38 years). The mean difference between POD5 and POM4 were 0.23° (P=.602) and 0.35° (P=.338) for the upper and lower bars, respectively. Bar position was virtually unchanged during the follow-up, and there was no bar dislocation or reoperation. A "bridge technique" designed to connect 2 parallel bars using plates and screws was demonstrated as a method to avoid pectus bar displacement. This approach was easy to implement without using sutures or invasive devices. Copyright © 2015 Elsevier Inc. All rights reserved.

To understand the knowledge and attitudes towards second hand smoking (SHS) among restaurant or bar patronage in five cities in China. 405 restaurants and bars were conveniently selected in 5 cities as Beijing, Wuhan, Xi'an, Kunming and Guiyang. From each of these hospitality venues, at least 3 patrons, including one smoker, one female non-smoker and one male nonsmoker were asked to answer a questionnaire on their knowledge and attitudes towards SHS and smoking policies in public places. 43.1% of the respondents had good knowledge on SHS hazards. 65% reported that those who smoked around them had never asked for their permission, and about 60% admitted that they had never asked others to stop smoking in front of them. There were almost two thirds of patrons reporting that they once felt discomfort of SHS in restaurants or bars, nearly half of whom chose to leave the venue to avoid exposure to SHS. Though majority of patrons supported '100% smoke-free hospitals, schools and public vehicles' initiations, the proportions of patrons that supporting '100% smoke-free restaurants and bars' initiations were only 30.0% and 19.8%, respectively. In Beijing, logistic regression model analyses showed that those who supporting 100% smoke-free restaurants and bars tended to be non-smokers, aged 25 years or older and to have had at least college education. Also in Beijing, those being female, having at least college education or non-smokers were more likely to choose restaurants and bars with smoking restrictions. Though knowledge on SHS hospitality patronage was still not high or popular for the public to refuse SHS exposure, banning smoking in hospitality venues was public's inclination and would become a trend in public health endeavor.

Bar-spheroid interaction in galaxies

NASA Technical Reports Server (NTRS)

Hernquist, Lars; Weinberg, Martin D.

1992-01-01

N-body simulation and linear analysis is employed to investigate the secular evolution of barred galaxies, with emphasis on the interaction between bars and spheroidal components of galaxies. This interaction is argued to drive secular transfer of angular momentum from bars to spheroids, primarily through resonant coupling. A moderately strong bar, having mass within corotation about 0.3 times the enclosed spheroid mass, is predicted to shed all its angular momentum typically in less than about 10 exp 9 yr. Even shorter depletion time scales are found for relatively more massive bars. It is suggested either that spheroids around barred galaxies are structured so as to inhibit strong coupling with bars, or that bars can form by unknown processes long after disks are established. The present models reinforce the notion that bars can drive secular evolution in galaxies.

Alcohol Mixed with Energy Drink Use as an Event-Level Predictor of Physical and Verbal Aggression in Bar Conflicts.

Miller, Kathleen E; Quigley, Brian M; Eliseo-Arras, Rebecca K; Ball, Natalie J

2016-01-01

Young adult use of alcohol mixed with caffeinated energy drinks (AmEDs) has been globally linked with increased odds of interpersonal aggression, compared with the use of alcohol alone. However, no prior research has linked these behaviors at the event level in bar drinking situations. The present study assessed whether AmED use is associated with the perpetration of verbal and physical aggression in bar conflicts at the event level. In Fall 2014, a community sample of 175 young adult AmED users (55% female) completed a web survey describing a recent conflict experienced while drinking in a bar. Use of both AmED and non-AmED alcoholic drinks in the incident were assessed, allowing calculation of our main predictor variable, the proportion of AmEDs consumed (AmED/total drinks consumed). To measure perpetration of aggression, participants reported on the occurrence of 6 verbal and 6 physical acts during the bar conflict incident. Linear regression analyses showed that the proportion of AmEDs consumed predicted scores for perpetration of both verbal aggression (β = 0.16, p < 0.05) and physical aggression (β = 0.19, p < 0.01) after controlling for gender, age, sensation-seeking and aggressive personality traits, aggressive alcohol expectancies, aggressogenic physical and social bar environments, and total number of drinks. Results of this study suggest that in alcohol-related bar conflicts, higher levels of young adult AmED use are associated with higher levels of aggression perpetration than alcohol use alone and that the elevated risk is not attributable to individual differences between AmED users and nonusers or to contextual differences in bar drinking settings. While future research is needed to identify motivations, dosages, and sequencing issues associated with AmED use, these beverages should be considered a potential risk factor in the escalation of aggressive bar conflicts.

In California, young adult tobacco prevention is of prime importance; 63% of smokers start by the age of 18 years, and 97% start by the age of 26 years. We examined social affiliation with 'peer crowd' (eg, Hipsters) as an innovative way to identify high-risk tobacco users. Cross-sectional surveys were conducted in 2014 (N=3368) among young adult bar patrons in 3 California cities. We examined use rates of five products (cigarettes, e-cigarettes, hookah, cigars and smokeless tobacco) by five race/ethnicity categories. Peer crowd affiliation was scored based on respondents' selecting pictures of young adults representing those most and least likely to be in their friend group. Respondents were classified into categories based on the highest score; the peer crowd score was also examined as a continuous predictor. Logistic regression models with each tobacco product as the outcome tested the unique contribution of peer crowd affiliation, controlling for race/ethnicity, age, sex, sexual orientation and city. Respondents affiliating with Hip Hop and Hipster peer crowds reported significantly higher rates of tobacco use. As a categorical predictor, peer crowd was related to tobacco use, independent of associations with race/ethnicity. As a continuous predictor, Hip Hop peer crowd affiliation was also associated with tobacco use, and Young Professional affiliation was negatively associated, independent of demographic factors. Tobacco product use is not the same across racial/ethnic groups or peer crowds, and peer crowd predicts tobacco use independent of race/ethnicity. Antitobacco interventions targeting peer crowds may be an effective way to reach young adult tobacco users. NCT01686178, Pre-results. Published by the BMJ Publishing Group Limited.

This study compares the sexual behavior and HIV prevalence of men and women at social venues where people meet new sexual partners in Eastern Kinshasa with that of sexually transmitted infection (STI) treatment and antenatal clinic (ANC) patients in the same area. ANC patients, STI clinic patients, and social venue patrons were interviewed, asked to provide a blood sample on-site, and provided with information about obtaining test results. Every patron at identified social venues in the study area was invited to participate. One thousand one hundred sixteen pregnant women; 66 male and 229 female STI clinic patients; and 952 male and 247 female patrons of social venues were interviewed and tested for HIV. HIV prevalence differed by group: ANC patients (4%); female venue patrons (12%); female STI patients (16%); male venue patrons (2%); and male STI patients (23%). HIV prevalence among sex workers at social venues (29%) was higher than HIV prevalence among other female patrons with new or multiple partnerships in the past four weeks (19%) and higher than HIV prevalence among female patrons denying sex work (6%). However, the absolute number of infected women was higher among women reporting recent new or multiple partnerships than among the smaller group of sex workers (23 vs. 18). Two-thirds of the infected female STI patients (24/36) reported no more than one and no new sexual partner in the past year. Improving prevention programs in Kinshasa is essential. Prevention efforts should not neglect women at social venues who do not self-identify as sex workers but who have high rates of new sexual partnership formation.

2011-01-01

Introduction and Aims In order to better understand the social context of barroom aggression, the aim was to identify common locations (“hotspots”) for aggression in bars and examine the association of hotspots with aggression severity and environmental characteristics. Design and Methods Aggression hotspots were identified using narrative descriptions and data recorded on premises’ floor plans for 1057 incidents of aggression collected in the Safer Bars evaluation. Hierarchical Linear Modeling was used to identify bar-level and night-level characteristics associated with each hotspot. Results The most common location for aggression was the dance floor (20.0% of incidents) or near the dance floor (11.5%), followed by near the serving bar (15.7%), at tables (13.1%), aisles, hallways and other areas of movement (6.2%), entrance (4.5%) and the pool playing area (4.1%). Hotspots were predicted mainly by bar-level characteristics, with dance floor aggression associated with crowded bars, a high proportion of female and young patrons, lots of sexual activity, a large number of patrons and staff, security staff present, better monitoring and coordination by staff, and people hanging around at closing. Incidents at tables and pool tables tended to occur in bars with the opposite characteristics. Nightly variations in patron intoxication and rowdiness were associated with aggression at tables while variations in crowding and sexual activity were associated with aggression in areas of movement. Incidents outside tended to be more severe. Discussion and Conclusions Each aggression location and their associated environments have somewhat different implications for staff training, premises design, policy and prevention. PMID:22050319

Barring intervention? Lesbian and gay bars as an underutilized venue for tobacco interventions.

PubMed

Leibel, Katherine; Lee, Joseph G L; Goldstein, Adam O; Ranney, Leah M

2011-07-01

Lesbian, gay, bisexual, and transgender (LGBT) communities are at high risk for tobacco use. While LGBT communities have historically considered bars to be safe places to socialize and congregate, these spaces are often tobacco-friendly environments and may have potential as sites for much needed intervention. Only a few public health interventions have attempted to work through bars and clubs to decrease tobacco use in the LGBT populations. Evidence from HIV prevention suggests some potential interventions in bars, and the tobacco industry has worked extensively (and successfully) to utilize bars in marketing efforts. Lesbian and gay bars are underutilized in tobacco control, suggesting missed avenues for chronic disease prevention programs. Researchers and communities should continue to recognize the importance of clean indoor air laws covering bars and develop additional strategies for reaching LGBT populations with disparities.

Nuss bar removal after minimally invasive repair of pectus excavatum in patients where bar ends are not palpable, can be a challenging procedure for the surgeon; a blind dissection toward the bar edges may lead to intercostal vessels or deep intercostal muscle injuries. In this article, we describe a fast, repeatable, low-cost technique to detect bar edge and stabilizers. A perioperative scan is performed by means of a portable ultrasonograph a few minutes before the operation. The bar edge stabilizer is detected as a hyperechogenic image with a concentric crescent while the bar edge is detected as a hyperechogenic dashed line with net edges. The scan is performed, and the actual projection on the skin of the metal plaque bulk is then labeled on the patient's chest by an ink marker. We believe that this method may improve morbidity, operative time, and consequently, hospitalization length and costs.

Introduction and Aims Although prevalence of alcohol consumption has been relatively stable among Thai youth, concerns over alcohol-related harms affecting youth influenced the passage of new laws in early 2008, which made it illegal to sell alcohol to anyone under the age of 20. This qualitative study explored the effects of the law on the purchasing patterns of underage Thai bar patrons, in order to understand the strategies employed by underage youth to circumvent the law. Design and Methods A total of 41 in-depth interviews were conducted with 18–19 year old bar patrons in Chiang Mai, Thailand. Results Underage Thai bar patrons frequented shops where enforcement was not strict and purchased alcohol, from familiar shopkeepers in their neighborhoods. Participants suggested that purchasing alcohol was relatively easy as long as shopkeepers were driven by the need to make a profit. Discussion and Conclusions To address alcohol-related harms, the control law must be enforced in a meaningful way to deter youth from purchasing alcohol. Otherwise, the law will have minimal effectiveness in reducing the harms associated with alcohol. PMID:22762793

Meeting potential sexual/romantic partners for mutual pleasure is one of the main reasons young adults go to bars. However, not all sexual contacts are positive and consensual, and aggression related to sexual advances is a common experience. Sometimes such aggression is related to misperceptions in making and receiving sexual advances while other times aggression reflects intentional harassment or other sexually aggressive acts. This study uses objective observational research to assess quantitatively gender of initiators and targets and the extent that sexual aggression involves intentional aggression by the initiator, the nature of responses by targets, and the role of third parties and intoxication. We analyzed 258 aggressive incidents involving sexual advances observed as part of a larger study on aggression in large capacity bars and clubs, using variables collected as part of the original research (gender, intoxication, intent) and variables coded from narrative descriptions (invasiveness, persistence, targets' responses, role of third parties). Hierarchical linear modeling analyses were used to account for nesting of incidents in evening and bars. Ninety percent of incidents involved male initiators and female targets, with almost all incidents involving intentional or probably intentional aggression. Targets mostly responded nonaggressively, usually using evasion. Staff rarely intervened; patron third parties intervened in 21% of incidents, usually to help the target but sometimes to encourage the initiator. initiators' level of invasiveness was related to intoxication of the targets, but not their own intoxication, suggesting intoxicated women were being targeted. Sexual aggression is a major problem in bars often reflecting intentional sexual invasiveness and unwanted persistence rather than misperceptions in sexual advances.

2002-01-01

Objectives: This study compared the mapping of natural language patron terms to the Medical Subject Headings (MeSH) across six MeSH interfaces for the MEDLINE database. Methods: Test data were obtained from search requests submitted by patrons to the Library of the Health Sciences, University of Illinois at Chicago, over a nine-month period. Search request statements were parsed into separate terms or phrases. Using print sources from the National Library of Medicine, Each parsed patron term was assigned corresponding MeSH terms. Each patron term was entered into each of the selected interfaces to determine how effectively they mapped to MeSH. Data were collected for mapping success, accessibility of MeSH term within mapped list, and total number of MeSH choices within each list. Results: The selected MEDLINE interfaces do not map the same patron term in the same way, nor do they consistently lead to what is considered the appropriate MeSH term. Conclusions: If searchers utilize the MEDLINE database to its fullest potential by mapping to MeSH, the results of the mapping will vary between interfaces. This variance may ultimately impact the search results. These differences should be considered when choosing a MEDLINE interface and when instructing end users. PMID:11999175

A computer-oriented procedure for solving the dynamic force analysis problem for general planar mechanisms is presented. This paper provides position analysis, velocity analysis, acceleration analysis and force analysis of six bar mechanism with variable topology approach. Six bar mechanism is constructed by joining two simple four bar mechanisms. Initially the position, velocity and acceleration analysis of first four bar mechanism are determined by using the input parameters. The outputs (angular displacement, velocity and acceleration of rocker)of first four bar mechanism are used as input parameter for the second four bar mechanism and the position, velocity, acceleration and forces are analyzed. With out-put parameters of second four-bar mechanism the force analysis of first four-bar mechanism is carried out.

2018-01-01

Despite the development of more researched and formulated orthodox medicines, herbal medicines continue to be well patronized for persons across the world with some patrons concurrently using both forms, oblivious of the unwanted effects that may occur. Using a multistage sampling procedure, a semistructured questionnaire was used to collect data in April 2016 from 240 informants from three selected hospitals and three herbal clinics in Tamale, a city in northern Ghana. Using Statistical Package for the Social Sciences, binary logistic regression was used to determine sociodemographic predictors of concurrent use of herbal and orthodox medicines. Orthodox medicines were the drug of choice for 54.2% and 49.2% of patrons of hospitals and herbal clinics, respectively. Also, 67.5% of herbal clinic patrons used orthodox medicines, while 25.0% of hospital attendees used herbal medications prior to their visit to the health facilities. Up to 17.9% of respondents concurrently used herbal and orthodox medicines for their prevailing ailment with age, less than 30 years being the only predictor of this habit (p = 0.015; 95% CI, 1.183–4.793; cOR = 2.4). All health professionals including those in herbal clinics should therefore be interested in the drug history of their clients. PMID:29743917

Because smoking rates are high among Vietnamese men, we used data from the 2007-2008 California Vietnamese Adult Tobacco Use Survey to estimate secondhand smoke exposure and associated risk factors among Vietnamese nonsmokers. Thirty percent of nonsmokers were exposed to secondhand smoke (SHS) at home, 8% at work, 52% in bars, and 67% on a college campus. At home, odds of SHS exposure were greater for women than for men and for adults aged less than 40 years than for older adults. Odds of SHS exposure were higher for former smokers at work (among employed men) and among men when in bars. Future interventions should consider sex, age, and smoking history in efforts to prevent SHS exposure among Vietnamese adults.

What makes the family of barred disc galaxies so rich: damping stellar bars in spinning haloes

NASA Astrophysics Data System (ADS)

Collier, Angela; Shlosman, Isaac; Heller, Clayton

2018-05-01

We model and analyse the secular evolution of stellar bars in spinning dark matter (DM) haloes with the cosmological spin λ ˜ 0-0.09. Using high-resolution stellar and DM numerical simulations, we focus on angular momentum exchange between stellar discs and DM haloes of various axisymmetric shapes - spherical, oblate, and prolate. We find that stellar bars experience a diverse evolution that is guided by the ability of parent haloes to absorb angular momentum, J, lost by the disc through the action of gravitational torques, resonant and non-resonant. We confirm that dynamical bar instability is accelerated via resonant J-transfer to the halo. Our main findings relate to the long-term secular evolution of disc-halo systems: with an increasing λ, bars experience less growth and basically dissolve after they pass through vertical buckling instability. Specifically, with increasing λ, (1) the vertical buckling instability in stellar bars colludes with inability of the inner halo to absorb J - this emerges as the main factor weakening or destroying bars in spinning haloes; (2) bars lose progressively less J, and their pattern speeds level off; (3) bars are smaller, and for λ ≳ 0.06 cease their growth completely following buckling; (4) bars in λ > 0.03 haloes have ratio of corotation-to-bar radii, RCR/Rb > 2, and represent so-called slow bars without offset dust lanes. We provide a quantitative analysis of J-transfer in disc-halo systems, and explain the reasons for absence of growth in fast spinning haloes and its observational corollaries. We conclude that stellar bar evolution is substantially more complex than anticipated, and bars are not as resilient as has been considered so far.

Secular Evolution in Barred Galaxies: Observations

NASA Astrophysics Data System (ADS)

Merrifield, M.

2002-12-01

This paper describes a framework for studying galaxy morphology, particularly bar strength, in a quantitative manner, and presents applications of this approach that reveal observational evidence for secular evolution in bar morphology. The distribution of bar strength in galaxies is quite strongly bimodal, suggesting that barred and unbarred systems are distinct entities, and that any evolution between these two states must occur on a relatively rapid timescale. Bars' strengths appear to be correlated with their pattern speeds, implying that these structures weaken as they start to slow, and disappear entirely before the bars have slowed significantly. There is also tantalizing evidence that bars are rare beyond a redshift of z ~ 0.7, indicating that galaxies have only recently evolved to a point where bars can readily form.

Mechanisms linking sediment supply and bar morphology: Results from a straight flume with alternate bars

NASA Astrophysics Data System (ADS)

Braudrick, C. A.; Minear, J. T.; Dietrich, W. E.; Dehart, M.; Sklar, L. S.

2008-12-01

One of the largest uncertainties in routing sediment through drainage networks is predicting the degree to which changes in sediment supply are mitigated by changes in sediment storage in bars. We hypothesize that changes in topographic steering link sediment supply and bar morphology. This hypothesis posits that increased sediment supply would enhance topographic steering over the bar, causing the bar to advance laterally into the pool. Contrarily, decreased supply would diminish topographic steering, causing bars to shrink laterally and pools to expand. We examined this hypothesis in a 28-m long, 0.86-m wide flume with a constant discharge of 5.4 l/s and sand with a median grain size of 0.8 mm. The conditions were sufficient to support alternate bars downstream of the upper 8-10 m, and the flume was run for approximately 65 hours at a constant discharge and sediment feed. The equilibrium slope was 0.0033. Once the channel reached equilibrium, the sediment feed was turned off while the discharge was held constant. During the first 25 hours after the feed was stopped, the sediment transport rate at the downstream end of the flume increased from 9.8 to 10.5 kg/hr as sediment was provided by incision at the upstream end of the flume. Because the bed was the only sediment source, sediment supply increased with distance down the flume. Once the feed was shut off, bar response differed between the upstream and downstream portions of the flume. Bars at the downstream end of the flume, where sediment supply increased relative to equilibrium conditions, swelled into the pool. These changes in bar morphology were accompanied by a decrease in surface grain size. Further upstream, where sediment supply was lower, the bars shrunk. These results suggest that there may be a linkage between topographic steering, bar morphology, and sediment supply, but further numerical tests and experimental manipulations are necessary to verify this linkage and to account for the effect of the

Effect of smoke-free patio policy of restaurants and bars on exposure to second-hand smoke.

PubMed

Azagba, Sunday

2015-07-01

While there is increasing support for restricting smoking in restaurant and bar patios, there is limited evidence on the effectiveness of this policy. This study examined the effect of smoke-free patio policy of restaurants and bars on adult second-hand smoke (SHS) exposure. Data were drawn from the 2005-2012 Canadian Tobacco Use Monitoring Survey (n=89,743), a repeated cross-sectional survey of youth and adult. Regression analysis, a quasi-experimental design was used to examine the effect of provincial smoke-free patio policy on self-reported exposure to SHS. Analyses suggest that exposure to SHS on patios of bars and restaurants declined following the adoption of provincial smoke-free patio policy. Relative to pre-policy SHS exposure, regression results showed a reduction in the probability of SHS exposure of up to 25% in Alberta. Similarly, in Nova Scotia, the probability of SHS exposure declined by up to 21%. Analyses stratified by smoking status found similar significant effect on both smokers and non-smokers. Findings suggest that provincial patio smoking ban on bars and restaurants had the intended effect of protecting non-smokers from SHS exposure. This study is consistent with a large body of evidence showing that a strong smoke-free legislation is an effective public health measure. Copyright © 2015 The Authors. Published by Elsevier Inc.

Material testing using the Kolsky bar, or split Hopkinson bar, technique has proven instrumental to conduct measurements of material behavior at strain rates in the order of 10 3 s -1. Test design and data reduction, however, remain empirical endeavors based on the experimentalist's experience. Issues such as wave propagation across discontinuities, the effect of the deformation of the bar surfaces in contact with the specimen, the effect of geometric features in tensile specimens (dog-bone shape), wave dispersion in the bars and other particulars are generally treated using simplified models. The work presented here was conducted in Q3 and Q4more » of FY14. The objective was to demonstrate the feasibility of numerical simulations of Kolsky bar tests, which was done successfully.« less

Bar quenching in gas-rich galaxies

NASA Astrophysics Data System (ADS)

Khoperskov, S.; Haywood, M.; Di Matteo, P.; Lehnert, M. D.; Combes, F.

2018-01-01

Galaxy surveys have suggested that rapid and sustained decrease in the star-formation rate (SFR), "quenching", in massive disk galaxies is frequently related to the presence of a bar. Optical and near-IR observations reveal that nearly 60% of disk galaxies in the local universe are barred, thus it is important to understand the relationship between bars and star formation in disk galaxies. Recent observational results imply that the Milky Way quenched about 9-10 Gyr ago, at the transition between the cessation of the growth of the kinematically hot, old, metal-poor thick disk and the kinematically colder, younger, and more metal-rich thin disk. Although perhaps coincidental, the quenching episode could also be related to the formation of the bar. Indeed the transfer of energy from the large-scale shear induced by the bar to increasing turbulent energy could stabilize the gaseous disk against wide-spread star formation and quench the galaxy. To explore the relation between bar formation and star formation in gas rich galaxies quantitatively, we simulated gas-rich disk isolated galaxies. Our simulations include prescriptions for star formation, stellar feedback, and for regulating the multi-phase interstellar medium. We find that the action of stellar bar efficiently quenches star formation, reducing the star-formation rate by a factor of ten in less than 1 Gyr. Analytical and self-consistent galaxy simulations with bars suggest that the action of the stellar bar increases the gas random motions within the co-rotation radius of the bar. Indeed, we detect an increase in the gas velocity dispersion up to 20-35 km s-1 at the end of the bar formation phase. The star-formation efficiency decreases rapidly, and in all of our models, the bar quenches the star formation in the galaxy. The star-formation efficiency is much lower in simulated barred compared to unbarred galaxies and more rapid bar formation implies more rapid quenching.

Star formation suppression and bar ages in nearby barred galaxies

NASA Astrophysics Data System (ADS)

James, P. A.; Percival, S. M.

2018-03-01

We present new spectroscopic data for 21 barred spiral galaxies, which we use to explore the effect of bars on disc star formation, and to place constraints on the characteristic lifetimes of bar episodes. The analysis centres on regions of heavily suppressed star formation activity, which we term `star formation deserts'. Long-slit optical spectroscopy is used to determine H β absorption strengths in these desert regions, and comparisons with theoretical stellar population models are used to determine the time since the last significant star formation activity, and hence the ages of the bars. We find typical ages of ˜1 Gyr, but with a broad range, much larger than would be expected from measurement errors alone, extending from ˜0.25 to >4 Gyr. Low-level residual star formation, or mixing of stars from outside the `desert' regions, could result in a doubling of these age estimates. The relatively young ages of the underlying populations coupled with the strong limits on the current star formation rule out a gradual exponential decline in activity, and hence support our assumption of an abrupt truncation event.

Magnetic Polarizability of Virtual (s\\bar{s}) and (c\\bar{c}) Pairs in the Nucleon

NASA Astrophysics Data System (ADS)

Filip, Peter

2017-12-01

We suggest 3 P 0 quantum state of virtual (s\\bar{s}) pairs in the nucleon can be polarised by the internal fields permeating the volume of the nucleon (proton or neutron). Due to the quadratic Zeeman interaction, 3 P 0 wavefunction of virtual (q\\bar{q}) pairs acquires the admixture of 1 P 10 quantum state in the magnetic field, which generates the antiparallel polarization of s and \\bar{s} quarks (in the nucleon). Considering the internal magnetic fields of neutron and proton (originating from their measured magnetic dipole moments), we suggest the induced s-quark polarization in the neutron to be of the oposite direction compared to the proton case. We mention the influence of the internal chromo-magnetic fields on the quantum state of (q\\bar{q}) pairs in the nucleon and we discuss also the expected behaviour of virtual (c\\bar{c}) pairs.

2012-04-01

Proper stress distribution on dental implants is necessary in bar-retained implant overlay dentures. We aimed to comparatively assess this stress distribution according to different bar heights using finite element models. A three-dimensional (3D) computer model of mandible with 2 implants (ITI, 4.1 mm diameter and 12 mm length) in canine areas and an overlying implant-supported bar-retained overlay denture were simulated with 0-, 1-, 2-, and 3-mm bar heights using ABAQUS software. A vertical force was applied to the left first molar and gradually increased from 0 to 50 N. The resultant stress distribution was evaluated. Bars of 1 and 2 mm in height transferred the least stress to the implants (3.882 and 3.896 MPa, respectively). The 0-mm height of the bar connection transferred the highest stress value (4.277 MPa). The amount of stress transferred by 3-mm heights of the bar connection was greater than that of 1- and 2-mm bar connections and smaller than that of 0-mm bar connection (4.165 kgN). This 3D finite element analysis study suggested that the use of Dolder bar attachment with 1- and 2-mm heights could be associated with appropriate stress distribution for implant-retained overlay dentures.

The aims of this study are: 1) to report indications of compliance with smoke-free legislation in Korean bars and restaurants in California; 2) to examine the demographic, smoking status, and acculturation factors of who smoked indoors; and 3) to report social cues in opposition to smoking among a sample of Koreans in California. Method Data were collected by telephone surveys administered by bilingual interviewers between 2007– 2009, and included California adults of Korean descent who visited a Korean bar or restaurant in a typical month (N=2,173, 55% female). Results 1% of restaurant-going participants smoked inside while 7% observed someone else smoke inside a Korean restaurant. 23% of bar-going participants smoked inside and 65% observed someone else smoke inside a Korean bar.

Contribution to volatile organic compound exposures from time spent in stores and restaurants and bars.

Many people spend time in stores and restaurants, yet there has been little investigation of the influence of these microenvironments on personal exposure. Relative to the outdoors, transportation, and the home, these microenvironments have high concentrations of several volatile organic compounds (VOCs). We developed a stochastic model to examine the effect of VOC concentrations in these microenvironments on total personal exposure for (1) non-smoking adults working in offices who spend time in stores and restaurants or bars and (2) non-smoking adults who work in these establishments. We also compared the effect of working in a smoking versus non-smoking restaurant or bar. Input concentrations for each microenvironment were developed from the literature whereas time activity inputs were taken from the National Human Activity Patterns Survey. Time-averaged exposures were simulated for 5000 individuals over a weeklong period for each analysis. Mean contributions to personal exposure from non-working time spent in stores and restaurants or bars range from <5% to 20%, depending on the VOC and time-activity patterns. At the 95th percentile of the distribution of the proportion of personal exposure attributable to time spent in stores and restaurants or bars, these microenvironments can be responsible for over half of a person's total exposure to certain VOCs. People working in restaurants or bars where smoking is allowed had the highest fraction of exposure attributable to their workplace. At the median, people who worked in stores or restaurants tended to have 20-60% of their total exposures from time spent at work. These results indicate that stores and restaurants can be large contributors to personal exposure to VOCs for both workers in those establishments and for a subset of people who visit these places, and that incorporation of these non-residential microenvironments can improve models of personal exposure distributions.

Galaxy Zoo: Observing secular evolution through bars

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

Cheung, Edmond; Faber, S. M.; Koo, David C.

In this paper, we use the Galaxy Zoo 2 data set to study the behavior of bars in disk galaxies as a function of specific star formation rate (SSFR) and bulge prominence. Our sample consists of 13,295 disk galaxies, with an overall (strong) bar fraction of 23.6% ± 0.4%, of which 1154 barred galaxies also have bar length (BL) measurements. These samples are the largest ever used to study the role of bars in galaxy evolution. We find that the likelihood of a galaxy hosting a bar is anticorrelated with SSFR, regardless of stellar mass or bulge prominence. We findmore » that the trends of bar likelihood and BL with bulge prominence are bimodal with SSFR. We interpret these observations using state-of-the-art simulations of bar evolution that include live halos and the effects of gas and star formation. We suggest our observed trends of bar likelihood with SSFR are driven by the gas fraction of the disks, a factor demonstrated to significantly retard both bar formation and evolution in models. We interpret the bimodal relationship between bulge prominence and bar properties as being due to the complicated effects of classical bulges and central mass concentrations on bar evolution and also to the growth of disky pseudobulges by bar evolution. These results represent empirical evidence for secular evolution driven by bars in disk galaxies. This work suggests that bars are not stagnant structures within disk galaxies but are a critical evolutionary driver of their host galaxies in the local universe (z < 1).« less

To meet the information needs of isolated primary care providers and their patients in the US Navy, a digital health sciences library, the Virtual Naval Hospital, was created through a unique partnership between academia and government. The creation of the digital library was heavily influenced by the principles of user-centered design and made allowances for the nomadic nature of the digital library's patrons and the heterogeneous access they have to Internet bandwidth. The result is a digital library that has been in operation since 1997, continues to expand in size, is heavily used, and is highly regarded by its patrons. The digital library is dedicated to delivering the right information at the right time to the right person so the right decision can be made, and therefore the Virtual Naval Hospital functions as a knowledge-management system for the US Navy Bureau of Medicine and Surgery.

Pectus excavatum results from dorsal deviation of the sternum causing narrowing of the anterior-posterior diameter of the chest. It can result in significant cosmetic deformities and cardiopulmonary compromise if severe. The Nuss procedure is a minimally invasive technique that involves placing a thin horizontally oriented metal bar below the dorsal sternal apex for correction of the pectus deformity. To identify the frequency and types of Nuss bar migrations, to present a new categorization of bar migrations, and to present examples of true migrations and pseudomigrations. We retrospectively reviewed the electronic medical records and all pertinent radiologic studies of 311 pediatric patients who underwent a Nuss procedure. We evaluated the frequency and type of bar migrations. Bar migration was demonstrated in 23 of 311 patients (7%) and occurred within a mean period of 26 days after surgery. Bar migrations were subjectively defined as deviation of the bar from the position demonstrated on the immediate postoperative radiographs and categorized as superior, inferior, rotation, lateral or flipped using a new classification system. Sixteen of the 23 migrations required re-operation. Nuss bar migration can be diagnosed with careful evaluation of serial radiographs. Nuss bar migration has a wide variety of appearances and requires exclusion of pseudomigration resulting from changes in patient positioning between radiologic examinations.

In the intervention condition (weeks 1 and 3), a 30-second antismoking advertisement-accentuating long-term health consequences of smoking and promoting cessation-was shown prior to all movies; in the control condition (weeks 2 and 4) no such spot was shown. (i) Awareness of smoking in the movie, (ii) approval of smoking in the movie, (iii) attitude towards smoking, (iv) intention to smoke in the future and (v) desire to smoke among smokers. Findings Patrons who were exposed to the antismoking advertisement were more likely to be female, but did not differ with respect to smoking status. After controlling for gender differences, patrons exposed to the antismoking advertisement had (i) higher awareness of smoking in the movies, (ii) lower levels of approval of smoking in the movies, and (iii) a more negative attitude towards smoking in general compared with those not exposed. Among smokers, smoking in the movies increased urge to smoke, but there was no interaction between smoking in the movies and experimental condition. Study results suggest that placing an antismoking advertisement before movies can affect attitudes towards smoking, bolstering evidence in support of such policies.

Impact of U.S. Smoke-free Air Laws on Restaurant and Bar Employment, 1990-2015.

PubMed

Shafer, Paul

2017-12-23

Secondhand smoke exposure is responsible for an estimated 50,000 deaths per year among nonsmokers in the U.S. Smoke-free air laws reduce secondhand smoke exposure but often encounter opposition over concerns about their economic impact. Expansion of these laws has stagnated and efforts to weaken existing laws may exacerbate existing disparities in exposure. Studies at the state and local levels have found that smoke-free air laws do not generally have an adverse effect, but there are no recent estimates of the impact of these laws nationally. Employment and sales are two measures commonly used to estimate the economic impact of smoke-free air laws. Sales data are gathered by state and local taxing authorities but not uniformly across jurisdictions. Dynamic panel models are used to estimate a population-weighted national average treatment effect of smoke-free air laws on restaurant and bar employment using data from the Quarterly Census of Employment and Wages for 1990 to 2015. A one-percentage point increase in population covered by a restaurant smoke-free air law is associated with a small increase (approximately 0.01%) in restaurant employment (b=0.0001, P<0.001). The percentage of state population covered by a bar smoke-free air law was not associated with bar employment. Smoke-free air laws are a powerful tool for protecting hospitality workers and patrons from the dangers of secondhand smoke. Using data over more than two decades, these results suggest that smoke-free air laws in the U.S. do not generally have any meaningful effect on restaurant and bar employment. Smoke-free air laws are associated with reductions in negative health outcomes and decreased smoking prevalence. Despite this clear public health argument and strong public support, passage of new laws has stagnated and exemptions are being used to weaken existing laws. The ability to make both a health and business case in support of existing laws may also bolster the case for expansion. This study

Interaction between a Mg17Al12 precipitate and { 10\\bar 12} < 10\\bar 12 > twin boundary in magnesium alloys

NASA Astrophysics Data System (ADS)

Li, B.; Mathaudhu, S. N.

Interactions between Mg17Al12 precipitates and { 10\\bar 12} < 10\\bar 1\\bar 1 > twin boundaries (TBs) in magnesium were studied by molecular dynamics simulations. The results obtained agree well with experimental observations in which precipitates can be entirely engulfed by { 10\\bar 12} < 10\\bar 1\\bar 1 > twins without being sheared. Structural analysis of the TBs in the atomic scale shows that the TBs are extremely incoherent during twin growth and highly deviate from the { 10\\bar 12} twinning plane as previously observed in a number of experiments. The simulation studies indicate that { 10\\bar 12} < 10\\bar 1\\bar 1 > twinning was accomplished solely by atomic shuffling that converts the parent lattice to the twin lattice without involving twinning dislocations, resulting in zero shear strain at the TBs.

We investigate the decay ofmore » $$\\bar B^0 \\to \\bar K^{*0} R$$ and $$\\bar B^0_s \\to \\phi R$$ with $R$ being the $X(4160)$, $Y(3940)$, $Z(3930)$ resonances. Under the assumption that these states are dynamically generated from the vector-vector interaction, as has been concluded from several theoretical studies, we use a reaction mechanism of quark production at the elementary level, followed by hadronization of one final $$q \\bar q$$ pair into two vectors and posterior final state interaction of this pair of vector mesons to produce the resonances. With this procedure we are able to predict five ratios for these decays, which are closely linked to the dynamical nature of these states, and also predict the order of magnitude of the branching ratios which we find of the order of $$10^{-4}$$, well within the present measurable range. In order to further test the dynamical nature of these resonances we study the $$\\bar B^0_s \\to \\phi D^* \\bar D^*$$ and $$\\bar B^0_s \\to \\phi D_s^* \\bar D_s^*$$ decays close to the $$D^* \\bar D^*$$ and $$D_s^* \\bar D_s^*$$ thresholds and make predictions for the ratio of the mass distributions in these decays and the $$\\bar B^0_s \\to \\phi R$$ decay widths. In conclusion, the measurement of these decays rates can help unravel the nature of these resonances.« less

The descriptive epidemiology of local restaurant smoking regulations in Massachusetts: an analysis of the protection of restaurant customers and workers.

2003-06-01

To describe the range of restaurant smoking regulations in the 351 cities and towns in Massachusetts, and to analyse the level of protection from secondhand smoke exposure guaranteed by these regulations. We obtained the local restaurant smoking regulations for each town, analysing them in terms of the protection of restaurant workers, bar workers, and adult and youth restaurant customers. The percentage of restaurant patrons and workers and bar workers who are protected from secondhand smoke exposure by the current smoking regulations in Massachusetts. As of June 2002, 225 towns had local restaurant smoking regulations. Of these, 69 (30.7%) do not allow smoking in restaurants, 10 (4.4%) restrict smoking to adult only restaurants, 64 (28.4%) restrict smoking to enclosed, separately ventilated areas, and 82 (36.4%) restrict smoking to areas that need not be enclosed and separately ventilated. Of the 174 towns that, at a minimum, restrict smoking to bar areas or separately ventilated areas, 35 (20.1%) allow variances. Overall, 60 towns, covering only 17.7% of the population, completely ban smoking in restaurants. As a result, 81.3% of adult restaurant customers, 81.2% of youth customers, 82.3% of restaurant workers, and 87.0% of bar workers are not guaranteed protection from secondhand smoke in restaurants. Despite the widespread adoption of local restaurant smoking regulations in Massachusetts, the majority of restaurant customers and workers remain unprotected from secondhand smoke exposure. In light of this, public health practitioners must stop compromising the protection of customers and workers from secondhand smoke exposure in restaurants.

2005-01-01

Objective: To meet the information needs of isolated primary care providers and their patients in the US Navy, a digital health sciences library, the Virtual Naval Hospital, was created through a unique partnership between academia and government. Methods: The creation of the digital library was heavily influenced by the principles of user-centered design and made allowances for the nomadic nature of the digital library's patrons and the heterogeneous access they have to Internet bandwidth. Results: The result is a digital library that has been in operation since 1997, continues to expand in size, is heavily used, and is highly regarded by its patrons. Conclusions: The digital library is dedicated to delivering the right information at the right time to the right person so the right decision can be made, and therefore the Virtual Naval Hospital functions as a knowledge-management system for the US Navy Bureau of Medicine and Surgery.

Interaction of real and virtual p p bar pairs in J / ψ → p p bar γ (ρ , ω) decays

2017-10-01

The p p bar invariant mass spectra of the processes J / ψ → p p bar ω, J / ψ → p p bar ρ, and J / ψ → p p bar γ close to the p p bar threshold are calculated by means of the N N bar optical potential. The potential model for N N bar interaction in the S10 state is proposed. The parameters of the model are obtained by fitting the cross section of N N bar scattering together with the p p bar invariant mass spectra of the J / ψ decays. Good agreement with the available experimental data is achieved. Using our potential and the Green's function approach we also describe the peak in the η‧π+π- invariant mass spectrum in the decay J / ψ → γη‧π+π- in the energy region near the N N bar threshold.

Membrane-Sculpting BAR Domains Generate Stable Lipid Microdomains

SUMMARY Bin-Amphiphysin-Rvs (BAR) domain proteins are central regulators of many cellular processes involving membrane dynamics. BAR domains sculpt phosphoinositide-rich membranes to generate membrane protrusions or invaginations. Here, we report that, in addition to regulating membrane geometry, BAR domains can generate extremely stable lipid microdomains by “freezing” phosphoinositide dynamics. This is a general feature of BAR domains, because the yeast endocytic BAR and Fes/CIP4 homology BAR (F-BAR) domains, the inverse BAR domain of Pinkbar, and the eisosomal BAR protein Lsp1 induced phosphoinositide clustering and halted lipid diffusion, despite differences in mechanisms of membrane interactions. Lsp1 displays comparable low diffusion rates in vitro and in vivo, suggesting that BAR domain proteins also generate stable phosphoinositide microdomains in cells. These results uncover a conserved role for BAR superfamily proteins in regulating lipid dynamics within membranes. Stable microdomains induced by BAR domain scaffolds and specific lipids can generate phase boundaries and diffusion barriers, which may have profound impacts on diverse cellular processes.

We carried out ^{12}CO(J = 1-0) observations toward bar and arm regions of the strongly barred galaxies NGC 1300 and NGC 5383 with the Nobeyama 45 m radio telescope (beam size of 1-2 kpc in the galaxies). The aim of the observations is to qualitatively examine a new scenario for the suppression of star formation in bars based on recent high-resolution numerical simulations: higher speed collisions between molecular clouds in the bar region compared with the arm region suppress the massive star formation. CO emissions were detected from all the regions, indicating the presence of molecular gases in the strong bars without associating clear H II regions. In both galaxies, the velocity width of the CO line profile tends to be larger in the bar region than in the arm region, which is qualitatively consistent with the new scenario.

1996-01-01

A survey was conducted to solicit data related to health professionals image of librarians. Physicians, residents, nurses, medical students, dentists, pharmacists, physical therapists, and occupational therapists were questioned about their experiences with and opinions of librarians, particularly the skills and characteristics needed by helpful, successful librarians. Health sciences librarians were also questioned about their own professional image and their perceptions of their patrons' impression of librarians. Librarians and health professionals alike ranked good communication as the most important skill for librarians. Computer or technological skills were ranked fourth by librarians but second by health professionals. Although librarians tended to describe themselves in slightly more positive terms than did their patrons, health professionals viewed librarians as approachable, responsive, supportive, and open to change. Health professionals also reported that they received accurate, reliable, and timely information from librarians and that this information was valuable. PMID:8883982

Why Are Some Galaxies Not Barred?

NASA Astrophysics Data System (ADS)

Saha, Kanak; Elmegreen, Bruce

2018-05-01

Although more than two-thirds of star-forming disk galaxies in the local universe are barred, some galaxies remain unbarred, occupying the upper half of the Hubble tuning fork diagram. Numerical simulations almost always produce bars spontaneously, so it remains a challenge to understand how galaxies sometimes prevent bars from forming. Using a set of collisionless simulations, we first reproduce the common result that cold stellar disks surrounding a classical bulge become strongly unstable to non-axisymmetric perturbations, leading to the rapid formation of spiral structure and bars. However, our analyses show that galaxy models with compact classical bulges (whose average density is greater than or comparable to the disk density calculated within bulge half-mass radii) are able to prevent bar formation for at least 4 Gyr even when the stellar disk is maximal and having low Toomre Q. Such bar prevention is the result of several factors such as (a) a small inner Lindblad resonance with a high angular rate, which contaminates an incipient bar with x 2 orbits, and (b) rapid loss of angular momentum accompanied by a rapid heating in the center from initially strong bar and spiral instabilities in a low-Q disk; in other words, a rapid initial rise to a value larger than ∼5 of the ratio of the random energy to the rotational energy in the central region of the galaxy.

An identity that relates multipolar solutions of the Einstein equations to Newtonian potentials of bars with linear densities proportional to Legendre polynomials is used to construct analytical potential-density pairs of infinitesimally thin bars with a given linear density profile. By means of a suitable transformation, softened bars that are free of singularities are also obtained. As an application we study the equilibrium points and stability for the motion of test particles in the gravitational field for three models of rotating bars.

Preparation of a Breadfruit Flour Bar.

Breadfruit is a nutritious, high energy food with a low quantity of protein but excellent protein quality. It has the potential to be developed into desired products which will help increase its utilization and add value to the crop. The overall purposes of this investigation were to develop a portable, nutritious, ready-to-eat breadfruit product (bar), test the sensory qualities of the product, and evaluate the nutritional properties of the product. Flour made from the Micronesian variety, Meinpadahk ( Artocarpus altilis × Artocarpus mariannensis ), was utilized for the development of the breadfruit bar. Breadfruit is a rich source of fiber, vitamins such as vitamin C, minerals such as potassium, and phytochemicals such as flavonoids. Nutritional labeling indicates that the breadfruit bar is high in carbohydrates and low in fat, and sensory evaluation indicates that 81% of the panelists found the bar acceptable while 19% disliked the bar. The breadfruit bar can provide an appealing and inexpensive gluten-free food source based on locally available breadfruit.

A survey of 183 patrons of a massage parlor in Illinois indicated that the typical customer is a 35-year-old married white male from out of town with 13 years of education who is employed in a lower- or middle-class job and goes to church on Sunday. He reports having had a variety of heterosexual experiences in the past, has come to the parlor because of lack of sexual partner at this particular time or because of curiosity, will come to orgasm during the genital massage, and will find it sexually satisfying. He is likely to have high self-esteem, consider himself personally and sexually adjusted, consider his value system liberal, and to be somewhat sympathetic to the goals of the women's rights movement.

A comparison was made of 72 men who were patrons in hotels with 6 A.M. or 7 A.M. opening, with a control group of 87 men interviewed in nearby hotels with 10 A.M. opening. The two groups were very similar on biographical characteristics, yet the men in the early-opening group consumed significantly more alcohol, had more drinking sessions, spent longer in drinking, and had significantly higher SMAST scores. The early opening was apparently facilitating problem drinking.

The intrinsic three-dimensional shape of galactic bars

Méndez-Abreu, J.; Costantin, L.; Aguerri, J. A. L.; de Lorenzo-Cáceres, A.; Corsini, E. M.

2018-06-01

We present the first statistical study on the intrinsic three-dimensional (3D) shape of a sample of 83 galactic bars extracted from the CALIFA survey. We use the galaXYZ code to derive the bar intrinsic shape with a statistical approach. The method uses only the geometric information (ellipticities and position angles) of bars and discs obtained from a multi-component photometric decomposition of the galaxy surface-brightness distributions. We find that bars are predominantly prolate-triaxial ellipsoids (68%), with a small fraction of oblate-triaxial ellipsoids (32%). The typical flattening (intrinsic C/A semiaxis ratio) of the bars in our sample is 0.34, which matches well the typical intrinsic flattening of stellar discs at these galaxy masses. We demonstrate that, for prolate-triaxial bars, the intrinsic shape of bars depends on the galaxy Hubble type and stellar mass (bars in massive S0 galaxies are thicker and more circular than those in less massive spirals). The bar intrinsic shape correlates with bulge, disc, and bar parameters. In particular with the bulge-to-total (B/T) luminosity ratio, disc g - r color, and central surface brightness of the bar, confirming the tight link between bars and their host galaxies. Combining the probability distributions of the intrinsic shape of bulges and bars in our sample we show that 52% (16%) of bulges are thicker (flatter) than the surrounding bar at 1σ level. We suggest that these percentages might be representative of the fraction of classical and disc-like bulges in our sample, respectively.

Development of ceramic-coated weld backing bars

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

Eggleston, B.R.

1994-10-20

In shipbuilding and many other industries, copper weld backing bars are used to draw the heat out of the weld. The problem that some users of these bars encounter is that these bars, on occasion, actually melt in spots and become welded to the weld plates. After this happens a number of times, the backing bar becomes so degraded that it must be either discarded or machined, both of which are very costly and time-consuming actions. To avoid this fusion between the backing bar and the weld plate, the weld processes that are used cannot be ones of high beatmore » input. This requirement is very limiting when thick plates are being welded. The plates must be beveled, and more weld passes must be run. These problems are also costly and time consuming. The aim of this project is to find a way to produce backing bars with nearly the same `chilling` effect but with both a greater resistance to molten metal and resistance to arcing to the backing bar itself. A possible solution currently being tested is to coat the copper bars with a thin layer of a ceramic coating. The procedure used was to coat the copper bars with either alumina or spinel by a plasma spraying method.« less

The Influence of Marijuana and Alcohol Use on Condom Use Behavior: Findings from a Sample of Young Adult Female Bar Drinkers

Parks, Kathleen A.; Collins, R. Lorraine; Derrick, Jaye L.

2012-01-01

Prevalence data indicate that alcohol and marijuana are frequently used intoxicants among young adults in the United States. In a number of studies, both alcohol use and marijuana use have been associated with failure to use condoms, a high risk sexual behavior. The purpose of the current study was to assess the individual and additive effects of alcohol and marijuana use on this risky sexual behavior among 251, young adult, female, bar drinkers. Multi-level modeling was used to assess the likelihood of condom use during sexual events that occurred as a function of substance use (none, only alcohol, only marijuana, or both) prior to and partner type during the event, as well as individual differences in sexual assertiveness. Initial model testing (level 1 and 2) revealed that there were significant main effects for partner type (known), substance use (alcohol and marijuana) and sexual assertiveness (refusal, pregnancy/STI prevention) on risky sex. Final model testing indicated that sexual assertiveness interacted with substance use to influence risky sex. Women who were low in sexual assertiveness refusal were more likely to engage in risky sex on days when they had consumed both alcohol and marijuana prior to the sexual activity. These findings highlight the complex nature of the relationship between substance use and risky sex. PMID:22612253

Unit-bar migration and bar-trough deposition: impacts on hydraulic conductivity and grain size heterogeneity in a sandy streambed

NASA Astrophysics Data System (ADS)

Korus, Jesse T.; Gilmore, Troy E.; Waszgis, Michele M.; Mittelstet, Aaron R.

2018-03-01

The hydrologic function of riverbeds is greatly dependent upon the spatiotemporal distribution of hydraulic conductivity and grain size. Vertical hydraulic conductivity ( K v) is highly variable in space and time, and controls the rate of stream-aquifer interaction. Links between sedimentary processes, deposits, and K v heterogeneity have not been well established from field studies. Unit bars are building blocks of fluvial deposits and are key to understanding controls on heterogeneity. This study links unit bar migration to K v and grain size variability in a sand-dominated, low-sinuosity stream in Nebraska (USA) during a single 10-day hydrologic event. An incipient bar formed parallel to the thalweg and was highly permeable and homogenous. During high flow, this bar was submerged under 10-20 cm of water and migrated 100 m downstream and toward the channel margin, where it became markedly heterogeneous. Low- K v zones formed in the subsequent heterogeneous bar downstream of the original 15-40-cm-thick bar front and past abandoned bridge pilings. These low- K v zones correspond to a discontinuous 1-cm layer of fine sand and silt deposited in the bar trough. Findings show that K v heterogeneity relates chiefly to the deposition of suspended materials in low-velocity zones downstream of the bar and obstructions, and to their subsequent burial by migration of the bar during high flow. Deposition of the unit bar itself, although it emplaced the vast majority of the sediment volume, was secondary to bar-trough deposition as a control on the overall pattern of heterogeneity.

Small proportions of actively-smoking patrons and high PM2.5 levels in southern California tribal casinos: support for smoking bans or designated smoking areas.

Nearly all California casinos currently allow smoking, which leads to potentially high patron exposure to secondhand tobacco smoke pollutants. Some argue that smoking restrictions or bans would result in a business drop, assuming > 50% of patrons smoke. Evidence in Nevada and responses from the 2008 California tobacco survey refute this assertion. The present study investigates the proportion of active smokers in southern California tribal casinos, as well as occupancy and PM(2.5) levels in smoking and nonsmoking sections. We measured active-smoker and total-patron counts during Friday or Saturday night visits (two per casino) to smoking and nonsmoking gaming areas inside 11 southern California casinos. We counted slot machines and table games in each section, deriving theoretical maximum capacities and occupancy rates. We also measured PM(2.5) concentrations (or used published levels) in both nonsmoking and smoking areas. Excluding one casino visit with extremely high occupancy, we counted 24,970 patrons during 21 casino visits of whom 1,737 were actively smoking, for an overall active- smoker proportion of 7.0% and a small range of ~5% across casino visits (minimum of 5% and maximum of 10%). The differences in mean inter-casino active-smoker proportions were not statistically significant. Derived occupancy rates were 24% to 215% in the main (low-stakes) smoking-allowed slot or table areas. No relationship was found between observed active-smoker proportions and occupancy rate. The derived maximum capacities of nonsmoking areas were 1% to 29% of the overall casino capacity (most under 10%) and their observed occupancies were 0.1 to over 3 times that of the main smoking-allowed casino areas.

Small proportions of actively-smoking patrons and high PM2.5 levels in southern California tribal casinos: support for smoking bans or designated smoking areas

PubMed Central

2012-01-01

Background Nearly all California casinos currently allow smoking, which leads to potentially high patron exposure to secondhand tobacco smoke pollutants. Some argue that smoking restrictions or bans would result in a business drop, assuming > 50% of patrons smoke. Evidence in Nevada and responses from the 2008 California tobacco survey refute this assertion. The present study investigates the proportion of active smokers in southern California tribal casinos, as well as occupancy and PM2.5 levels in smoking and nonsmoking sections. Methods We measured active-smoker and total-patron counts during Friday or Saturday night visits (two per casino) to smoking and nonsmoking gaming areas inside 11 southern California casinos. We counted slot machines and table games in each section, deriving theoretical maximum capacities and occupancy rates. We also measured PM2.5 concentrations (or used published levels) in both nonsmoking and smoking areas. Results Excluding one casino visit with extremely high occupancy, we counted 24,970 patrons during 21 casino visits of whom 1,737 were actively smoking, for an overall active- smoker proportion of 7.0% and a small range of ~5% across casino visits (minimum of 5% and maximum of 10%). The differences in mean inter-casino active-smoker proportions were not statistically significant. Derived occupancy rates were 24% to 215% in the main (low-stakes) smoking-allowed slot or table areas. No relationship was found between observed active-smoker proportions and occupancy rate. The derived maximum capacities of nonsmoking areas were 1% to 29% of the overall casino capacity (most under 10%) and their observed occupancies were 0.1 to over 3 times that of the main smoking-allowed casino areas.

Limiting swimming pool outbreaks of cryptosporidiosis - the roles of regulations, staff, patrons and research.

PubMed

Ryan, Una; Lawler, Sheleigh; Reid, Simon

2017-02-01

Cryptosporidium is the leading cause of swimming pool outbreaks of gastroenteritis. Transmission occurs through the ingestion of oocysts that are passed in the faeces of an infected person or animal when an accidental faecal release event occurs. Cryptosporidium parasites present specific challenges for infection control as oocysts are highly resistant to chlorine levels used for pool disinfection, infected individuals can shed large numbers of oocysts, there is a long incubation period and shedding of oocysts occurs even after symptom resolution. The purposes of this review are to identify key barriers to limiting swimming pool-associated outbreaks of cryptosporidiosis and to outline needs for research and collaboration to advance co-ordinated management practices. We reviewed swimming pool-associated cryptosporidiosis outbreaks, disinfection teachniques, current regulations and the role of staff and patrons. Key barriers to limiting swimming pool-associated outbreaks of cryptosporidiosis are a lack of uniform national and international standards, poor adherence and understanding of regulations governing staff and patron behaviour, and low levels of public knowledge and awareness.

BAR domain proteins regulate Rho GTPase signaling.

PubMed

Aspenström, Pontus

2014-01-01

BAR proteins comprise a heterogeneous group of multi-domain proteins with diverse biological functions. The common denominator is the Bin-Amphiphysin-Rvs (BAR) domain that not only confers targeting to lipid bilayers, but also provides scaffolding to mold lipid membranes into concave or convex surfaces. This function of BAR proteins is an important determinant in the dynamic reconstruction of membrane vesicles, as well as of the plasma membrane. Several BAR proteins function as linkers between cytoskeletal regulation and membrane dynamics. These links are provided by direct interactions between BAR proteins and actin-nucleation-promoting factors of the Wiskott-Aldrich syndrome protein family and the Diaphanous-related formins. The Rho GTPases are key factors for orchestration of this intricate interplay. This review describes how BAR proteins regulate the activity of Rho GTPases, as well as how Rho GTPases regulate the function of BAR proteins. This mutual collaboration is a central factor in the regulation of vital cellular processes, such as cell migration, cytokinesis, intracellular transport, endocytosis, and exocytosis.

Use of Highly Fortified Products among US Adults

2015-01-01

It is complicated to ascertain the composition and prevalence of the use of highly fortified food and supplement products (HFPs) because HFP foods and HFP supplements have different labeling requirements. However, HFPs (energy bars, energy drinks, sports drinks, protein bars, energy shots, and fortified foods/beverages) are popular in the United States. A web-based survey balanced to reflect US census data was used to describe their use in a sample of 2,355 US adults >18 yr in 2011 and trends in their use from 2005. In 2011, 33% of adults reported using HFP; use was significantly higher among males, African Americans, Hispanics, and more highly educated individuals (e.g. some college or more) and those <45 yr compared to non-users. Multiple product use was common. Of users, 46% consumed sports drinks, 37% fortified foods/beverages, 32% protein bars, 27% energy drinks, 24% energy bars, and 12% energy shots. For those HFP products as a group, prevalence of use was 36% (n=2039) in 2005, 35% in 2009 (n=2010), and 30% in 2011 (n=2355). Although use was significantly lower in 2011 than in 2005 especially among females, non-Hispanics, and those with high school education or less (P≤0.05). HFP, particularly energy and sports drinks, continue to be widely used by many U.S. adults. PMID:26823624

Why Buckling Stellar Bars Weaken in Disk Galaxies

NASA Astrophysics Data System (ADS)

Martinez-Valpuesta, Inma; Shlosman, Isaac

2004-09-01

Young stellar bars in disk galaxies experience a vertical buckling instability that terminates their growth and thickens them, resulting in a characteristic peanut/boxy shape when viewed edge-on. Using N-body simulations of galactic disks embedded in live halos, we have analyzed the bar structure throughout this instability and found that the outer (approximately) third of the bar dissolves completely while the inner part (within the vertical inner Lindblad resonance) becomes less oval. The bar acquires the frequently observed peanut/boxy-shaped isophotes. We also find that the bar buckling is responsible for a mass injection above the plane, which is subsequently trapped by specific three-dimensional families of periodic orbits of particular shapes explaining the observed isophotes, in line with previous work. Using a three-dimensional orbit analysis and surfaces of sections, we infer that the outer part of the bar is dissolved by a rapidly widening stochastic region around its corotation radius-a process related to the bar growth. This leads to a dramatic decrease in the bar size, decrease in the overall bar strength, and a mild increase in its pattern speed but is not expected to lead to a complete bar dissolution. The buckling instability appears primarily responsible for shortening the secular diffusion timescale to a dynamical one when building the boxy isophotes. The sufficiently long timescale of the described evolution, ~1 Gyr, can affect the observed bar fraction in the local universe and at higher redshifts, both through reduced bar strength and the absence of dust offset lanes in the bar.

The origin of the LMC stellar bar: clues from the SFH of the bar and inner disc

Monteagudo, L.; Gallart, C.; Monelli, M.; Bernard, E. J.; Stetson, P. B.

2018-01-01

We discuss the origin of the Large Magellanic Cloud (LMC) stellar bar by comparing the star formation histories (SFHs) obtained from deep colour-magnitude diagrams (CMDs) in the bar and in a number of fields in different directions within the inner disc. The CMDs, reaching the oldest main-sequence turn-offs in these very crowded fields, have been obtained with VIMOS on the Very Large Telescope in the service mode, under very good seeing conditions. We show that the SFHs of all fields share the same patterns, with consistent variations of the star formation rate as a function of time in all of them. We therefore conclude that no specific event of star formation can be identified with the formation of the LMC bar, which instead likely formed from a redistribution of disc material which occurred when the LMC disc became bar unstable, and shared a common SFH with the inner disc thereafter. The strong similarity between the SFH of the centre and edge of the bar rules out the expected significant spatial variations of the SFH across the bar.

The descriptive epidemiology of local restaurant smoking regulations in Massachusetts: an analysis of the protection of restaurant customers and workers

PubMed Central

Skeer, M; Siegel, M

2003-01-01

Objectives: To describe the range of restaurant smoking regulations in the 351 cities and towns in Massachusetts, and to analyse the level of protection from secondhand smoke exposure guaranteed by these regulations. Design: We obtained the local restaurant smoking regulations for each town, analysing them in terms of the protection of restaurant workers, bar workers, and adult and youth restaurant customers. Main outcome measure: The percentage of restaurant patrons and workers and bar workers who are protected from secondhand smoke exposure by the current smoking regulations in Massachusetts. Results: As of June 2002, 225 towns had local restaurant smoking regulations. Of these, 69 (30.7%) do not allow smoking in restaurants, 10 (4.4%) restrict smoking to adult only restaurants, 64 (28.4%) restrict smoking to enclosed, separately ventilated areas, and 82 (36.4%) restrict smoking to areas that need not be enclosed and separately ventilated. Of the 174 towns that, at a minimum, restrict smoking to bar areas or separately ventilated areas, 35 (20.1%) allow variances. Overall, 60 towns, covering only 17.7% of the population, completely ban smoking in restaurants. As a result, 81.3% of adult restaurant customers, 81.2% of youth customers, 82.3% of restaurant workers, and 87.0% of bar workers are not guaranteed protection from secondhand smoke in restaurants. Conclusions: Despite the widespread adoption of local restaurant smoking regulations in Massachusetts, the majority of restaurant customers and workers remain unprotected from secondhand smoke exposure. In light of this, public health practitioners must stop compromising the protection of customers and workers from secondhand smoke exposure in restaurants. PMID:12773735

Influence of the weighing bar size to determine optimal time of biodiesel-glycerol separation by using the buoyancy weighing-bar method

The buoyancy weighing-bar method is a novel method in the particle size distribution measurement. This method can measure particle size distributions of the settling particles and floating particles. In this study, the buoyancy weighing-bar method is applied to determine optimal time of biodiesel-glycerol separation. The buoyancy weighing-bar method can be applied to determine the separation time because biodiesel and glycerol have the different densities. The influences of diameter of weighing-bar by using the buoyancy weighing-bar method would be experimentally investigated. The diameters of weighing-bar in this experiment are 8 mm, 10 mm, 15 mm and 20 mm, while the graduated cylinder (diameter : 65 mm) is used as vessel. The samples used in this experiment are the mixture of 95 % of biodiesel and 5 % of glycerol. The data obtained by the buoyancy weighing-bar method are analized by using the gas chromatography to determine the purity of biodiesel. Based on the data obtained, the buoyancy weighing-bar method can be used to detect the separation time of biodiesel-glycerol by using the weighing-bar diameter of 8 mm, 10 mm, 15 mm and 20 mm, but the most accuracy in determination the biodiesel-glycerol separation time is obtained by using the weighing-bar diameter of 20 mm. The biodiesel purity of 97.97 % could be detected at 64 minutes by using the buoyancy weighing-bar method when the weighing-bar diameter of 20 mm is used.

To assess grocery store patrons' perceptions of a comprehensive medication review (CMR) compared with traditional prescription medication counseling. Self-administered survey. Eight central Ohio grocery stores during January through April 2007. Grocery store patrons. Survey events. Responses to survey items about CMRs and prescription medication counseling indicated (1) who study participants would expect to deliver each program, (2) where they would expect services to be offered, and (3) what they would expect to be included or discussed. Predefined response options were provided for each question. The majority of the 214 study participants associated physicians or pharmacists with a CMR. CMRs were thought to be provided in medical offices or pharmacies. Only 3 of 24 qualifiers were statistically significantly different when comparing CMRs and prescription medication counseling (inclusion of health and wellness screenings [55% vs. 43%, P = 0.015], discussion about any of the patients' medications being the same [45% vs. 56%, P = 0.026] and "other" [6% vs. 12%, P = 0.021]). Patients may not recognize pharmacists as primary providers of CMRs and may not see a clear distinction between a CMR and prescription medication counseling. More research is needed in this area to further solidify the results. Pharmacists need to market themselves as willing and capable individuals of providing CMRs. Additionally, pharmacists should highlight key differences between a CMR and prescription medication counseling so that patients understand the value of a CMR.

Gender-based violence is a well-recognized risk factor for HIV infection among women. Alcohol use is associated with both gender-based violence and sexual risk behavior, but has not been examined as a correlate of both in a context of both high HIV risk and hazardous drinking. The purpose of this paper is to examine the association between recent abuse by a sex partner with alcohol and sexual risk behavior among female patrons of alcohol serving venues in South Africa. Specifically, the aim of this study is to determine whether sexual risk behaviors are associated with gender-based violence after controlling for levels of alcohol use. We surveyed 1,388 women attending informal drinking establishments in Cape Town, South Africa to assess recent history of gender-based violence, drinking, and sexual risk behaviors. Gender-based violence was associated with both drinking and sexual risk behaviors after controlling for demographics among the women. A hierarchical logistic regression analysis showed that after controlling for alcohol use sexual risk behavior remained significantly associated with gender-based violence, particularly with meeting a new sex partner at the bar, recent STI diagnosis, and engaging in transactional sex, but not protected intercourse or number of partners. In South Africa where heavy drinking is prevalent women may be at particular risk of physical abuse from intimate partners as well as higher sexual risk. Interventions that aim to reduce gender-based violence and sexual risk behaviors must directly work to reduce drinking behavior.

Introduction: The present study examined the reduction in exposure to tobacco smoke in German hospitality venues following the implementation of a partial smoking ban by measuring the indoor air concentration of PM2.5 in 2005 and 2009, that is, before and after the legislation was implemented. Methods: The concentration of respirable suspended particles (PM2.5) in the indoor air of German hospitality venues was measured using a laser photometer (AM510). The prelegislation sample from 2005 included 80 venues of which 58 could be revisited in 2009. After replenishment, the postlegislation sample consisted of 79 venues. Results: Compared with the prelegislation measurement, the concentration of PM2.5 in hospitality venues was reduced significantly after introduction of the smoke-free legislation. The median mass concentration of PM2.5 was reduced by 87.1% in coffee bars, by 88.7% in restaurants, by 66.3% in bars, and by 90.8% in discotheques. Notably, legal exemptions to the smoking ban are an issue: At the postlegislation measurement in 2009, the mass concentrations of PM2.5 were substantially higher in venues allowing smoking in the whole venue or in a designated smoking room than in completely smoke-free venues. Conclusions: The German smoke-free legislation significantly reduced the levels of respirable suspended particles in the indoor air of hospitality venues, benefiting the health of employees and patrons alike. But legal exemptions attenuated the effectiveness of the policy. PMID:21622497

This study aimed to (1) quantify the respective physical workloads of bar bending and fixing; and (2) compare the physiological and perceptual responses between bar benders and bar fixers. Field studies were conducted during the summer in Hong Kong from July 2011 to August 2011 over six construction sites. Synchronized physiological, perceptual, and environmental parameters were measured from construction rebar workers. The average duration of the 39 field measurements was 151.1 ± 22.4 min under hot environment (WBGT = 31.4 ± 2.2 °C), during which physiological, perceptual and environmental parameters were synchronized. Energy expenditure of overall rebar work, bar bending, and bar fixing were 2.57, 2.26 and 2.67 Kcal/min (179, 158 and 186 W), respectively. Bar fixing induced significantly higher physiological responses in heart rate (113.6 vs. 102.3 beat/min, p < 0.05), oxygen consumption (9.53 vs. 7.14 ml/min/kg, p < 0.05), and energy expenditure (2.67 vs. 2.26 Kcal/min, p < 0.05) (186 vs. 158 W, p < 0.05) as compared to bar bending. Perceptual response was higher in bar fixing but such difference was not statistically significant. Findings of this study enable the calculation of daily energy expenditure of rebar work.

2008-08-31

In two recent reactions by Belle producing DD-bar and DD-bar* meson pairs, peaks above threshold have been measured in the differential cross sections, possibly indicating new resonances in these channels. We want to study such reactions from the point of view that the D meson pairs are produced from already known or predicted resonances below threshold. Our study shows that the peak in the DD-bar* production is not likely to be caused by the X(3872) resonance, but the peak seen in DD-bar invariant mass can be well described if the DD-bar pair comes from the already predicted scalar X(3700) resonance.

Characterizing bars in low surface brightness disc galaxies

NASA Astrophysics Data System (ADS)

Peters, Wesley; Kuzio de Naray, Rachel

2018-05-01

In this paper, we use B-band, I-band, and 3.6 μm azimuthal light profiles of four low surface brightness galaxies (LSBs; UGC 628, F568-1, F568-3, F563-V2) to characterize three bar parameters: length, strength, and corotation radius. We employ three techniques to measure the radius of the bars, including a new method using the azimuthal light profiles. We find comparable bar radii between the I-band and 3.6 μm for all four galaxies when using our azimuthal light profile method, and that our bar lengths are comparable to those in high surface brightness galaxies (HSBs). In addition, we find the bar strengths for our galaxies to be smaller than those for HSBs. Finally, we use Fourier transforms of the B-band, I-band, and 3.6 μm images to characterize the bars as either `fast' or `slow' by measuring the corotation radius via phase profiles. When using the B- and I-band phase crossings, we find three of our galaxies have faster than expected relative bar pattern speeds for galaxies expected to be embedded in centrally dense cold dark matter haloes. When using the B-band and 3.6 μm phase crossings, we find more ambiguous results, although the relative bar pattern speeds are still faster than expected. Since we find a very slow bar in F563-V2, we are confident that we are able to differentiate between fast and slow bars. Finally, we find no relation between bar strength and relative bar pattern speed when comparing our LSBs to HSBs.

Tidally Induced Bars of Galaxies in Clusters

Using N-body simulations, we study the formation and evolution of tidally induced bars in disky galaxies in clusters. Our progenitor is a massive, late-type galaxy similar to the Milky Way, composed of an exponential disk and a Navarro-Frenk-White dark matter halo. We place the galaxy on four different orbits in a Virgo-like cluster and evolve it for 10 Gyr. As a reference case, we also evolve the same model in isolation. Tidally induced bars form on all orbits soon after the first pericenter passage and survive until the end of the evolution. They appear earlier, are stronger and longer, and have lower pattern speeds for tighter orbits. Only for the tightest orbit are the properties of the bar controlled by the orientation of the tidal torque from the cluster at pericenter. The mechanism behind the formation of the bars is the angular momentum transfer from the galaxy stellar component to its halo. All of the bars undergo extended periods of buckling instability that occur earlier and lead to more pronounced boxy/peanut shapes when the tidal forces are stronger. Using all simulation outputs of galaxies at different evolutionary stages, we construct a toy model of the galaxy population in the cluster and measure the average bar strength and bar fraction as a function of clustercentric radius. Both are found to be mildly decreasing functions of radius. We conclude that tidal forces can trigger bar formation in cluster cores, but not in the outskirts, and thus can cause larger concentrations of barred galaxies toward the cluster center.

The research describes the characteristics and motivations of youthful San Diego County residents who patronize the bars and nightclubs in Tijuana, Mexico. Two random-digit-dial surveys of San Diego County residents-one group aged 18-20 years and one aged 21-30 years-was conducted during a 2-year period. Those who reported having visited the bars in Tijuana in the last year were compared with those who had not. All respondents were residents of San Diego County, California, USA. The study comprised 2200 youths between 18 and 30 years of age. The interview protocol included questions covering demographic characteristics, drinking and drug-use history, experience with Tijuana bars, and ratings of bar features in San Diego and Tijuana. About half of the 18-20-year-olds and a third of the 21-30-year-olds reported visiting bars in Tijuana at least once in the past 12 months. Race, age, gender, heavy drinking and drug-use history were significantly associated with visits to Tijuana bars. The price of alcohol and the perceived freedom to get drunk in Tijuana bars were considered attractive features leading to cross-border drinking. The features of the alcohol service in Mexican bars that attract youthful drinkers (low cost and liberal availability of alcohol, lack of formal controls, and presence of heavy drinkers) are similar to those present in other drinking locales that lead to drunkenness. Thus, a better understanding of the characteristics and motivations of the US youths patronizing bars in Tijuana can lead to improved interventions to reduce heavy, risky drinking.

Little is known about tobacco promotion activities in low and middle-income countries. Information on tobacco sales, advertisement and promotion in bars, cafes and nightclubs is needed to develop interventions to reduce smoking initiation and relapse, particularly among youths and young adults. To evaluate cigarette sales and tobacco advertisement and promotion in bars, cafes and nightclubs using a volunteer survey approach in large cities throughout the world. Between 2007 and 2009, we administered an interview-based survey to 231 bar/cafe/nightclub owners/managers in 24 large cities in Africa, the Americas, Asia and eastern Europe. Cigarette sales and tobacco advertisement and promotions were found in bars/cafes/nightclubs in most cities. Examples of promotions included cigarette giveaways and event sponsorship. Establishments that allowed smoking were more likely to sell cigarettes compared to smoke-free establishments (OR 8.67, 95% CI 3.25 to 23.1). Larger establishments (maximum occupancy ≥ 100 vs <100 customers) were more likely to have tobacco advertising (OR 4.35, 95% CI 2.04 to 9.24) and to receive promotional items from tobacco companies (OR 3.18, 95% CI 1.41 to 7.17). Cigarette sales and tobacco promotions were common in bars, cafes and nightclubs in the majority of cities. Socialising and hospitality venues must be covered by legislation banning tobacco sales and promotions to limit exposure among populations at high risk of tobacco initiation and relapse from quitting.

Community pharmacies vary widely in terms of ownership structures, location, and dispensing policies. It is unknown if an association exists between the type of community pharmacy and the degree of medication adherence exhibited by patrons-patients. To describe adherence to statin therapy among subjects patronizing different types of community pharmacy categories (department- mass merchandise, chain-franchise, and independent-banner) in Saskatchewan, Canada, between 2000 and 2005. Study data were obtained from the Saskatchewan Drug Plan and Extended Benefits database, which is maintained by the government of Saskatchewan, Canada. The study included all subjects who (a) filled a statin prescription within selected community pharmacies between January 1, 2000, and December 31, 2005; (b) had no record of statin prescriptions during the year prior to the first statin prescription, according to the records of the Saskatchewan Drug Plan and Extended Benefits; and (c) demonstrated active utilization in the drug plan database for at least 1 year after the first statin prescription. The proxy criterion for activity was any dispensing record for statin or nonstatin medications at least 1 year following the index claim. Statin adherence level was estimated as tablets per day, defined as the total number of tablets dispensed divided by the total number of days of observation. Each subject's observation period began on the index date and ended on the earlier of (a) 30 days after the last recorded fill for any type of prescription medication (statin or nonstatin), or (b) December 31, 2005. The primary end point was the proportion of subjects within each pharmacy category who maintained an adherence level of 80% or greater during their individual observation period. Additional adherence calculations were performed for each of 3 time periods, beginning on the index date and ending on days 365, 729, and 1094 (i.e., 1, 2, and 3 years). Patients were included in the analysis for each

Bar coding for the medication administration step of the drug-use process is discussed. FDA will propose a rule in 2003 that would require bar-code labels on all human drugs and biologicals. Even with an FDA mandate, manufacturer procrastination and possible shifts in product availability are likely to slow progress. Such delays should not preclude health systems from adopting bar-code-enabled point-of-care (BPOC) systems to achieve gains in patient safety. Bar-code technology is a replacement for traditional keyboard data entry. The elements of bar coding are content, which determines the meaning; data format, which refers to the embedded data and symbology, which describes the "font" in which the machine-readable code is written. For a BPOC system to deliver an acceptable level of patient protection, the hospital must first establish reliable processes for a patient identification band, caregiver badge, and medication bar coding. Medications can have either drug-specific or patient-specific bar codes. Both varieties result in the desired code that supports patient's five rights of drug administration. When medications are not available from the manufacturer in immediate-container bar-coded packaging, other means of applying the bar code must be devised, including the use of repackaging equipment, overwrapping, manual bar coding, and outsourcing. Virtually all medications should be bar coded, the bar code on the label should be easily readable, and appropriate policies, procedures, and checks should be in place. Bar coding has the potential to be not only cost-effective but to produce a return on investment. By bar coding patient identification tags, caregiver badges, and immediate-container medications, health systems can substantially increase patient safety during medication administration.

The BAR domain is the eponymous domain of the "BAR-domain protein superfamily", a large and diverse set of mostly multi-domain proteins that play eminent roles at the membrane cytoskeleton interface. BAR domain homodimers are the functional units that peripherally associate with lipid membranes and are involved in membrane sculpting activities. Differences in their intrinsic curvatures and lipid-binding properties account for a large variety in membrane modulating properties. Membrane activities of BAR domains are further modified and regulated by intramolecular or inter-subunit domains, by intermolecular protein interactions, and by posttranslational modifications. Rather than providing detailed cell biological information on single members of this superfamily, this review focuses on biochemical, biophysical, and structural aspects and on recent findings that paradigmatically promote our understanding of processes driven and modulated by BAR domains.

Influence of the weighing bar position in vessel on measurement of cement’s particle size distribution by using the buoyancy weighing-bar method

The buoyancy weighing-bar method is a new simple and cost-effective method to determine the particle size distribution both settling and floating particle. In this method, the density change in a suspension due to particle migration is measured by weighing buoyancy against a weighing-bar hung in the suspension, and then the particle size distribution is calculated using the length of the bar and the time-course change in the mass of the bar. The apparatus of this method consists of a weighing-bar and an analytical balance with a hook for under-floor weighing. The weighing bar is used to detect the density change in suspension. In this study we investigate the influences of position of weighing bar in vessel on settling particle size distribution measurements of cement by using the buoyancy weighing-bar method. The vessel used in this experiment is graduated cylinder with the diameter of 65 mm and the position of weighing bar is in center and off center of vessel. The diameter of weighing bar in this experiment is 10 mm, and the kerosene is used as a dispersion liquids. The results obtained show that the positions of weighing bar in vessel have no significant effect on determination the cement’s particle size distribution by using buoyancy weighing-bar method, and the results obtained are comparable to those measured by using settling balance method.

A Modern Picture of Barred Galaxy Dynamics

Petersen, Michael; Weinberg, Martin; Katz, Neal

Observations of disk galaxies suggest that bars are responsible for altering global galaxy parameters (e.g. structures, gas fraction, star formation rate). The canonical understanding of the mechanisms underpinning bar-driven secular dynamics in disk galaxies has been largely built upon the analysis of linear theory, despite galactic bars being clearly demonstrated to be nonlinear phenomena in n-body simulations. We present simulations of barred Milky Way-like galaxy models designed to elucidate nonlinear barred galaxy dynamics. We have developed two new methodologies for analyzing n-body simulations that give the best of both powerful analytic linear theory and brute force simulation analysis: orbit family identification and multicomponent torque analysis. The software will be offered publicly to the community for their own simulation analysis.The orbit classifier reveals that the details of kinematic components in galactic disks (e.g. the bar, bulge, thin disk, and thick disk components) are powerful discriminators of evolutionary paradigms (i.e. violent instabilities and secular evolution) as well as the basic parameters of the dark matter halo (mass distribution, angular momentum distribution). Multicomponent torque analysis provides a thorough accounting of the transfer of angular momentum between orbits, global patterns, and distinct components in order to better explain the underlying physics which govern the secular evolution of barred disk galaxies.Using these methodologies, we are able to identify the successes and failures of linear theory and traditional n-body simulations en route to a detailed understanding of the control bars exhibit over secular evolution in galaxies. We present explanations for observed physical and velocity structures in observations of barred galaxies alongside predictions for how structures will vary with dynamical properties from galaxy to galaxy as well as over the lifetime of a galaxy, finding that the transfer of angular

THE NATURE AND NURTURE OF BARS AND DISKS

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

Mendez-Abreu, J.; Aguerri, J. A. L.; Zarattini, S.

The effects that interactions produce on galaxy disks and how they modify the subsequent formation of bars need to be distinguished to fully understand the relationship between bars and environment. To this aim we derive the bar fraction in three different environments ranging from the field to Virgo and Coma Clusters, covering an unprecedentedly large range of galaxy luminosities (or, equivalently, stellar masses). We confirm that the fraction of barred galaxies strongly depends on galaxy luminosity. We also show that the difference between the bar fraction distributions as a function of galaxy luminosity (and mass) in the field and Comamore » Cluster is statistically significant, with Virgo being an intermediate case. The fraction of barred galaxies shows a maximum of about 50% at M{sub r} {approx_equal} - 20.5 in clusters, whereas the peak is shifted to M{sub r} {approx_equal} - 19 in the field. We interpret this result as a variation of the effect of environment on bar formation depending on galaxy luminosity. We speculate that brighter disk galaxies are stable enough against interactions to keep their cold structure, thus, the interactions are able to trigger bar formation. For fainter galaxies, the interactions become strong enough to heat up the disks inhibiting bar formation and even destroying the disks. Finally, we point out that the controversy regarding whether the bar fraction depends on environment could be resolved by taking into account the different luminosity ranges probed by the galaxy samples studied so far.« less

Scroll bar growth on the coastal Trinity River, TX, USA

Mason, J.; Hassenruck-Gudipati, H. J.; Mohrig, D. C.

2017-12-01

The processes leading to the formation and growth of scroll bars remain relatively mysterious despite how often they are referenced in fluvial literature. Their definition is descriptive; they are characterized as arcuate topographic highs present on the inner banks of channel bends on meandering rivers, landward of point bars. Often, they are used as proxies for previous positions of point bars. This assumption of a one-to-one correspondence between point bars and scroll bars should be reconsidered as 1) planform curvature for scroll bars is consistently smaller than the curvature for adjacent point bars, and 2) deposition on the scroll bar is typically distinct and disconnected from the adjacent point bar deposition. Results from time-lapse airborne lidar data as well as from trenches through five separate scroll bar - point bar pairings on the Trinity River in east TX, USA, will be discussed in relation to formative scroll bar processes and their connection to point bars. On the lidar difference map, scroll bar growth appears as a strip of increased deposition flanked on both the land- and channel-ward sides by areas with no or limited deposition. Trenches perpendicular to these scrolls typically show a base of dune-scale cross stratification interpreted to be associated with a previous position of the point bar. These dune sets are overlain by sets of climbing-ripple cross-strata that form the core of the modern scroll bar and preserve a record of multiple transport directions (away from, towards, and parallel to the channel). Preliminary Trinity River grain-size analyses show that the constructional scrolls are enriched in all grain sizes less than 250 microns in diameter, while point bars are enriched in all grain sizes above this cut off. Scroll bars are hypothesized to be akin to levees along the inner banks of channels-flow expansion caused by the presence of point bars induces deposition of suspended sediment that defines the positions of the scroll bars.

Nutritional Evaluation of NASA's Rodent Food Bar Diet

2000-01-01

Tests are being conducted on NASA's rodent Food Bar in preparation for long-term use as the rat and mouse diet aboard the International Space Station. Nutritional analyses are performed after the bars are manufactured and then repeated periodically to determine nutritional stability. The primary factors analyzed are protein, ash, fat, fiber, moisture, amino acids, fatty acids, and minerals. Nutrient levels are compared to values published in the National Research Council's dietary requirements for rodents, and also to those contained in several commonly used commercial rodent lab diets. The Food Bar is manufactured from a powdered diet to which moisture is added as it is processed through an extruder. The bars are dipped into potassium sorbate, vacuum-sealed, and irradiated. In order to determine nutrient changes during extrusion and irradiation, the powdered diet, the non-irradiated bars, and the irradiated bars are all analyzed. We have observed lower values for some nutrients (iodine, vitamin K, and iron) in the Food Bars compared with NRC requirements. Many nutrients in the Food Bars are contained at a higher level than levels in the NRC requirements. An additional factor we are investigating is the 26% moisture level in the Food Bars, which drops to about 15% within a week, compared to a stable 10% moisture in many standard lab chow diets. In addition to the nutritional analyses, the food bar is being fed to several strains of rats and mice, and feeding study and necropsy results are being observed (Barrett et al, unpublished data). Information from the nutritional analyses and from the rodent studies will enable us to recommend the formulation that will most adequately meet the rodent Food Bar requirements for long-term use aboard the Space Station.

Multi-wavelength observations of barred, flocculent galaxies

NASA Astrophysics Data System (ADS)

Ratay, Douglas Lee

Although it is generally accepted that large galaxies form through the assemblage of smaller objects, an explanation for the morphology of galaxies is not available. Any complete theory of galaxy morphology must include production and dissolution mechanisms for galactic bars, rings, nuclear bars, spiral arms, and companions. This theory does not exist because of the lack of detailed data from many types of galaxies in different environments. We have defined a new sample of galaxies which are simultaneously flocculent, barred, and isolated. We have performed optical, near-infrared, and radio (HI) observations of the galaxies in this sample. We measured properties of our galaxies including bar length, bar axis ratio, HI diameter, HI mass, and dynamical mass. We found that our sample group is heterogeneous, and compares well to a standard samples of galaxies. We found two of our galaxies to possess companions, and two others to show evidence of current interactions. This is consistent with other observations indicating that local isolated galaxies do not possess a large number of small companions. We cannot rule out the possibility of very small companions. We find that as a group our sample is slightly less luminous than normal galaxies and may be more likely to be involved in interactions. We conclude that the bar and spiral arm features in our sample are due to processes internal to the galaxies, likely involving the interaction between the galactic disk and halo. We defined a control sample of barred, grand design galaxies to further determine the acceptability of barred, flocculent galaxies as a physically meaningful subset of galaxies.

Challenges for the smoking ban in Israeli pubs and bars: analysis guided by the behavioral ecological model

PubMed Central

2012-01-01

Background The latest amendment to the ban on smoking in public places in Israel was implemented in 2007, adding pubs and bars (P&B) to the list of public places in which smoking is prohibited. However, smoking in most P&B continued. The aim of the study was to identify the theoretically plausible reasons for the partial success of a public ban on smoking in P&B settings. Explanations provided by P&B owners were interpreted as probable causal factors based on the Behavioral Ecological Model (BEM). Methods Qualitative interviews were performed with 36 P&B owners in Tel-Aviv and 18 Israeli towns and cities of various population size. Results P&B owners reported a variety of situational factors (i.e., contingencies) and reinforcers as likely explanations of the partial failure of the legislated ban on smoking in public places, particularly P&B. The major reinforcers for non-adherence with the law were no or low frequency of inspections and low penalties from authorities. P&B owners also feared loss of customers and revenue if bans were enforced in their own establishment but not in competing establishments. Finally, owners reported social norms prevailing among some Israeli patrons supporting smoking in P&B settings, in part to express opposition to the new law. Conclusions Qualitative assessment can uncover probable social situations that operate to prevent greater adherence to smoking bans. The results warrant confirmation by quantitative analyses. Policies with mandated inspections and penalty requirements that are implemented in all bars without prejudice could lead to greater adherence to smoking bans. Positive reinforcing consequences that encourage adherence (such as publicity and support from non-smokers) would be more likely to generate both greater adherence to the policy and good will toward the government. Principles of behavior outlined in the BEM offer guidance for designing quantitative confirmation analyses of future bans. PMID:22913392

Nearshore bars and the break-point hypothesis

The set of hypotheses calling for bar formation at the break point was tested with field data. During two different experiments, waves were measured across the surf zone coincident with the development of a nearshore bar. We use a criterion, based on the wave height to depth ratio, to determine the offshore limit of the inner surf zone. During the first experiment, the bar became better developed and migrated offshore while remaining well within the inner surf zone. During the second experiment, the surf zone was narrower and we cannot rule out the possibility of break point processes contributing to bar development. We conclude that bars are not necessarily coupled with the break point and can become better developed and migrate offshore while being in the inner surf zone landward from initial wave breaking in the outer surf zone. ?? 1989.

Basalt Fiber Reinforced Polymer (BFRP) bars have the advantages of corrosion resistance, high strength, light weight, good dielectric properties, and they are new type of green reinforced alternative material. In order to determine the mechanical properties of BFRP bars, the tensile strength of basalt fiber bars was necessary to be studied. The diameters of the basalt fiber bars were compared by means of uniaxial tensile test in this article. Then the stress-strain curve can be drawn out. The results show that the stress - strain curve of BFRP bars present straight line relation, and there is no sign before failure; there is no yield platform on the stress-strain curve of BFRP bars, which are typical brittle material;the tensile strength of BFRP bars is about 3 times higher than that of ordinary steel bars. and the elastic modulus is about 1/5 of that of ordinary steel; the ultimate tensile strength of BFRP bars varies little with the increase of diameter, but there exist some differences in modulus values.

The aim of this study is to evaluate the effect of different cross-sections of bar connecting two implants on the retention of mandibular overdentures with Hader clip or lined with heat-cured resilient liner as a housing material. The retentive values after simulated 1.5 years of service were also recorded. Edentulous mandibular acrylic model was constructed with two dummy implants located in the canine region and connected with cast bar assembly. According to bar cross-section and anchoring method, four groups ( n = 10) of identical overdentures were used as Hader bar/clip group (HCG), Hader bar/silicone liner female housing group (HSG), oval bar/silicone liner female housing group (OSG), and round bar/silicone liner female housing group (RSG). Each overdenture sample was subjected to simulated wear up to 2740 manual insertions/separations. The mean retentive forces were measured at the baseline and after every 500 insertions. The data were statistically analyzed using one-way analysis of variance. The present study demonstrated that all bar cross-sections showed a significant difference at the baseline ( P < 0.05), but HSG showed greater initial retention compared to HCG, OSG, and RSG. OSG showed a significant higher retention after 2740 insertions (simulated five insertions/day). Within the limitation of this in vitro study and for a similar period of service, heat-cured silicone female housing for Hader bar could maintain greater retention for two-implant-retained overdentures than provided by conventional plastic clip after 1.5 year. The oval bar recorded reasonable initial retention values and maintained these values for 1.5 years of service.

In observations, it is important to deproject the two fundamental quantities characterizing a bar, i.e., its length (a) and ellipticity (e), to face-on values before any careful analyses. However, systematic estimation on the uncertainties of the commonly used deprojection methods is still lacking. Simulated galaxies are well suited in this study. We project two simulated barred galaxies onto a two-dimensional (2D) plane with different bar orientations and disk inclination angles (i). Bar properties are measured and deprojected with the popular deprojection methods in the literature. Generally speaking, deprojection uncertainties increase with increasing i. All of the deprojection methods behave badlymore » when i is larger than 60°, due to the vertical thickness of the bar. Thus, future statistical studies of barred galaxies should exclude galaxies more inclined than 60°. At moderate inclination angles (i ≤ 60°), 2D deprojection methods (analytical and image stretching), and Fourier-based methods (Fourier decomposition and bar-interbar contrast) perform reasonably well with uncertainties ∼10% in both the bar length and ellipticity, whereas the uncertainties of the one-dimensional (1D) analytical deprojection can be as high as 100% in certain extreme cases. We find that different bar measurement methods show systematic differences in the deprojection uncertainties. We further discuss the deprojection uncertainty factors with the emphasis on the most important one, i.e., the three-dimensional structure of the bar itself. We construct two triaxial toy bar models that can qualitatively reproduce the results of the 1D and 2D analytical deprojections; they confirm that the vertical thickness of the bar is the main source of uncertainties.« less

Gender-based violence is a well-recognized risk factor for HIV infection among women. Alcohol use is associated with both gender-based violence and sexual risk behavior, but has not been examined as a correlate of both in a context of both high HIV risk and hazardous drinking. The purpose of this paper is to examine the association between recent abuse by a sex partner with alcohol and sexual risk behavior among female patrons of alcohol serving venues in South Africa. Specifically, the aim of this study is to determine whether sexual risk behaviors are associated with gender-based violence after controlling for levels of alcohol use. We surveyed 1,388 women attending informal drinking establishments in Cape Town, South Africa to assess recent history of gender-based violence, drinking, and sexual risk behaviors. Gender-based violence was associated with both drinking and sexual risk behaviors after controlling for demographics among the women. A hierarchical logistic regression analysis showed that after controlling for alcohol use sexual risk behavior remained significantly associated with gender-based violence, particularly with meeting a new sex partner at the bar, recent STI diagnosis, and engaging in transactional sex, but not protected intercourse or number of partners. In South Africa where heavy drinking is prevalent women may be at particular risk of physical abuse from intimate partners as well as higher sexual risk. Interventions that aim to reduce gender-based violence and sexual risk behaviors must directly work to reduce drinking behavior. PMID:22526526

Bars in Field and Cluster Galaxies at Intermediate Redshifts

Barazza, F. D.; Jablonka, P.; Ediscs Collaboration

2009-12-01

We present the first study of large-scale bars in clusters at intermediate redshifts (z=0.4-0.8). We compare the properties of the bars and their host galaxies in the clusters with those of a field sample in the same redshift range. We use a sample of 945 moderately inclined disk galaxies drawn from the EDisCS project. The morphological classification of the galaxies and the detection of bars are based on deep HST/ACS F814W images. The total optical bar fraction in the redshift range z=0.4-0.8, averaged over the entire sample, is 25%. This is lower than found locally, but in good agreement with studies of bars in field environments at intermediate redshifts. For the cluster and field subsamples, we measure bar fractions of 24% and 29%, respectively. In agreement with local studies, we find that disk-dominated galaxies have a higher bar fraction than bulge-dominated galaxies. We also find, based on a small subsample, that bars in clusters are on average longer than in the field and preferentially found close to the cluster center, where the bar fraction is somewhat higher than at larger distances.

Laboratory and Workplace Assessments of Rivet Bucking Bar Vibration Emissions

2016-01-01

Sheet metal workers operating rivet bucking bars are at risk of developing hand and wrist musculoskeletal disorders associated with exposures to hand-transmitted vibrations and forceful exertions required to operate these hand tools. New bucking bar technologies have been introduced in efforts to reduce workplace vibration exposures to these workers. However, the efficacy of these new bucking bar designs has not been well documented. While there are standardized laboratory-based methodologies for assessing the vibration emissions of many types of powered hand tools, no such standard exists for rivet bucking bars. Therefore, this study included the development of a laboratory-based method for assessing bucking bar vibrations which utilizes a simulated riveting task. With this method, this study evaluated three traditional steel bucking bars, three similarly shaped tungsten alloy bars, and three bars featuring spring-dampeners. For comparison the bucking bar vibrations were also assessed during three typical riveting tasks at a large aircraft maintenance facility. The bucking bars were rank-ordered in terms of unweighted and frequency-weighted acceleration measured at the hand-tool interface. The results suggest that the developed laboratory method is a reasonable technique for ranking bucking bar vibration emissions; the lab-based riveting simulations produced similar rankings to the workplace rankings. However, the laboratory-based acceleration averages were considerably lower than the workplace measurements. These observations suggest that the laboratory test results are acceptable for comparing and screening bucking bars, but the laboratory measurements should not be directly used for assessing the risk of workplace bucking bar vibration exposures. The newer bucking bar technologies exhibited significantly reduced vibrations compared to the traditional steel bars. The results of this study, together with other information such as rivet quality, productivity, tool

In this study, the impact of conventional lok-bars for CT-simulation (CIVCO-bar) and treatment (iBEAM-bar) were compared with a novel lok-bar (mHM-bar) in tomotherapy. Verification was obtained as follows: i. artifacts in CT images; ii. dose attenuation rate of lok-bar, compared to without lok-bar; and iii. dose differences between the calculated and measured absorbed doses. With the CIVCO-bar, there were obvious metal artifacts, while there were nearly no artifacts with the mHM-bar. The mean dose attenuation rates with the mHM-bar and iBEAM-bar were 1.31% and 2.28%, and the mean dose difference was 1.55% and 1.66% for mHM-bar and iBEAM-bar. Using the mHM-bar reduced artifacts on the CT image and improved dose attenuation are obtained. The lok-bar needs to be inserted as a structure set in treatment planning with tomotherapy.

This study explored perceptions of HIV following local introduction of antiretroviral therapy (ART), among 30 HIV-positive and -negative female sex workers (FSWs) and 10 male bar patrons in Mombasa, Kenya. Semi-structured interviews were analyzed qualitatively to identify determinants of sexual risk behaviors. ART was not perceived as a barrier to safer sex and in some cases led to decreased high-risk behaviors. Barriers to safer sex included economic pressure and sexual partnership types. Many women reported that negotiating condom use is more difficult in long-term partnerships. These women favored short-term partnerships to minimize risk through consistent condom use. For women living with HIV, concern about maintaining health and avoiding HIV superinfection was a strong motivator of protective behaviors. For HIV-negative women, a negative HIV test was a powerful motivator. Incorporation of context- and serostatus-specific factors (e.g., self-protection for HIV-positive women) into tailored prevention counseling may support high-risk women to reduce risk behaviors.

Herein we present a simple, rapid and low cost strategy for the preparation of robust stir bar coatings based on the combination of montmorillonite with epoxy resin. The composite stir bar was implemented in a novel automated multisyringe stir bar sorptive extraction system (MS-SBSE), and applied to the extraction of four chlorophenols (4-chlorophenol, 2,4-dichlorophenol, 2,4,6-trichlorophenol and pentachlorophenol) as model compounds, followed by high performance liquid chromatography-diode array detection. The different experimental parameters of the MS-SBSE, such as sample volume, selection of the desorption solvent, desorption volume, desorption time, sample solution pH, salt effect and extraction time were studied. Under the optimum conditions, the detection limits were between 0.02 and 0.34μgL(-1). Relative standard deviations (RSD) of the method for the analytes at 10μgL(-1) concentration level ranged from 3.5% to 4.1% (as intra-day RSD) and from 3.9% to 4.3% (as inter-day RSD at 50μgL(-1) concentration level). Batch-to-batch reproducibility for three different stir bars was 4.6-5.1%. The enrichment factors were between 30 and 49. In order to investigate the capability of the developed technique for real sample analysis, well water, wastewater and leachates from a solid waste treatment plant were satisfactorily analyzed.

A preliminary measurement of |V{sub cb}| and the branching fraction {Beta}({bar B}{sup 0} {yields} D*{sup +}{ell}{sup -}{bar {nu}}{sub {ell}}) has been performed based on a sample of about 55,700 {bar B}{sup 0} {yields} D*{sup +}{ell}{sup -}{bar {nu}}{sub {ell}} decays recorded with the BABAR detector. The decays are identified in the D*{sup +} {yields} D{sup 0}{pi}{sup +} final state, with the D{sup 0} reconstructed in three different decay modes. The differential decay rate is measured as a function of the relativistic boost of the D*{sup +} in the {bar B}{sup 0} rest frame. The value of the differential decay rate atmore » ''zero recoil'', namely the point at which the D*{sup +} is at rest in the {bar B}{sup 0} frame, is predicted in Heavy Quark Effective Theory as a kinematic factor times F(1)|V{sub cb}|, where F is the unique form factor governing the decay. We extrapolate the measured differential decay rate to the zero recoil point and obtain F(1)|V{sub cb}| = (34.03 {+-} 0.24 {+-} 1.31) x 10{sup -3}. Using a theoretical calculation for F(1) we extract |V{sub cb}| = (37.27 {+-} 0.26(stat.) {+-} 1.43(syst.){sub -1.2}{sup +1.5}(theo.)) x 10{sup -3}.

Sheet metal workers operating rivet bucking bars are at risk of developing hand and wrist musculoskeletal disorders associated with exposures to hand-transmitted vibrations and forceful exertions required to operate these hand tools. New bucking bar technologies have been introduced in efforts to reduce workplace vibration exposures to these workers. However, the efficacy of these new bucking bar designs has not been well documented. While there are standardized laboratory-based methodologies for assessing the vibration emissions of many types of powered hand tools, no such standard exists for rivet bucking bars. Therefore, this study included the development of a laboratory-based method for assessing bucking bar vibrations which utilizes a simulated riveting task. With this method, this study evaluated three traditional steel bucking bars, three similarly shaped tungsten alloy bars, and three bars featuring spring-dampeners. For comparison the bucking bar vibrations were also assessed during three typical riveting tasks at a large aircraft maintenance facility. The bucking bars were rank-ordered in terms of unweighted and frequency-weighted acceleration measured at the hand-tool interface. The results suggest that the developed laboratory method is a reasonable technique for ranking bucking bar vibration emissions; the lab-based riveting simulations produced similar rankings to the workplace rankings. However, the laboratory-based acceleration averages were considerably lower than the workplace measurements. These observations suggest that the laboratory test results are acceptable for comparing and screening bucking bars, but the laboratory measurements should not be directly used for assessing the risk of workplace bucking bar vibration exposures. The newer bucking bar technologies exhibited significantly reduced vibrations compared to the traditional steel bars. The results of this study, together with other information such as rivet quality, productivity, tool

To investigate the role of bars in the chemical evolution of isolated disc galaxies, we performed a series of 39 gas dynamical simulations of isolated barred and unbarred galaxies with various masses, initial gas fractions, and AGN feedback models. The presence of a bar drives a substantial amount of gas toward the central region of the galaxy. In the most massive galaxies, this results in a violent starburst, followed by a drop in star formation resulting from gas exhaustion. The time delay between Type Ia and Type II supernovae explosions means that barred galaxies experience a rapid increase in [O/H] in the central region, and a much more gradual increase in [Fe/H]. In unbarred galaxies, star formation proceeds at a slow and steady rate, and oxygen and iron are produced at steady rates which are similar except for a time offset. Comparing the abundance ratios in barred and unbarred galaxies with the same central stellar mass M*, we find in barred galaxies an enhancement of 0.07 dex in [O/H], 0.05 dex in [Fe/H], and 0.05 dex in [O/Fe]. The [O/H] enhancement is in excellent agreement with observations from the SDSS. The initial gas fraction has very little effect on the abundance ratios in barred and unbarred galaxies, unless the galaxies experience a starburst. We considered AGN-host galaxies located near the bottom of the AGN regime, M* ≳ 3 × 1010M⊙, where AGN feedback dominates over supernovae feedback. We found that the impact of AGN feedback on the central abundances is marginal.

Bridge-indentation precracking of glass bars

Lue, J.L.; Scattergood, R.O.

1993-07-01

Bridge indentation precracking was first reported by Sadahiro et al., and has been used by a number of subsequent investigators. The procedure involves placing a half-penny starter crack, formed by Vickers indentation, at the center of the bottom surface of a rectangular bar specimen. The bar is loaded between pusher and anvil platens. The bridge span S produces tensile bending stress on the bottom surface of the bar, which contains the starter crack. With increasing load, the crack grows stably outward and inward, and at a certain load the crack will propagate unstably (pop-in) to a straight, through-section crack ofmore » length c. The method is very convenient for producing sharp, through-section precracks in ceramic bars without the need for saw cutting or fatigue cycling. However, the effects of bridge geometry and friction on the precracking results will be presented here which point to an important influence of the friction between the specimen and anvil platens.« less

This study aims at assessing the mechanical behavior of a composite metal/polymer bar to be implanted in the retrosternal position, in order to correct chest wall deformities, such as Pectus Excavatum. A 300-mm-long, 12.7-mm-wide, and 3.5-mm-thick Nuss bar was considered, made of different metals and biodegradable polymers, fixed at its extremities, and with a constant force of 250 N applied on its center. Two different geometries for the metal elements to be embedded in the polymeric matrix were tested: in the former, thin metal sheets and in the latter, cylindrical metal reinforcing rods were considered. Finite element method simulation results are reported, in terms of maximum stress and strain of the bar. Furthermore, the maximum stress values obtained by varying metal sheet thickness or rod diameter (and therefore the volumetric percentage of metal within the matrix) for different material combinations are also shown; optimal configuration for the Pectus Excavatum treatment was finally identified for a composite Nuss bar.

THE MASS PROFILE AND SHAPE OF BARS IN THE SPITZER SURVEY OF STELLAR STRUCTURE IN GALAXIES (S{sup 4}G): SEARCH FOR AN AGE INDICATOR FOR BARS

We have measured the radial light profiles and global shapes of bars using two-dimensional 3.6 μm image decompositions for 144 face-on barred galaxies from the Spitzer Survey of Stellar Structure in Galaxies. The bar surface brightness profile is correlated with the stellar mass and bulge-to-total (B/T) ratio of their host galaxies. Bars in massive and bulge-dominated galaxies (B/T > 0.2) show a flat profile, while bars in less massive, disk-dominated galaxies (B/T ∼ 0) show an exponential, disk-like profile with a wider spread in the radial profile than in the bulge-dominated galaxies. The global two-dimensional shapes of bars, however, are rectangular/boxy, independentmore » of the bulge or disk properties. We speculate that because bars are formed out of disks, bars initially have an exponential (disk-like) profile that evolves over time, trapping more disk stars to boxy bar orbits. This leads bars to become stronger and have flatter profiles. The narrow spread of bar radial profiles in more massive disks suggests that these bars formed earlier (z > 1), while the disk-like profiles and a larger spread in the radial profile in less massive systems imply a later and more gradual evolution, consistent with the cosmological evolution of bars inferred from observational studies. Therefore, we expect that the flatness of the bar profile can be used as a dynamical age indicator of the bar to measure the time elapsed since the bar formation. We argue that cosmic gas accretion is required to explain our results on bar profile and the presence of gas within the bar region.« less

2015-01-01

The use of near-surface mounted (NSM) fibre-reinforced polymer (FRP) bars is an interesting method for increasing the shear and flexural strength of existing timber members. This article examines the behaviour of carbon FRP (CFRP) bars in timber under direct pull-out conditions. The objective of this experimental program is to investigate the bond strength between composite bars and timber: bars were epoxied into small notches made into chestnut and fir wood members using a commercially-available epoxy system. Bonded lengths varied from 150 to 300 mm. Failure modes, stress and strain distributions and the bond strength of CFRP bars have been evaluated and discussed. The pull-out capacity in NSM CFRP bars at the onset of debonding increased with bonded length up to a length of 250 mm. While CFRP bar’s pull-out was achieved only for specimens with bonded lengths of 150 and 200 mm, bar tensile failure was mainly recorded for bonded lengths of 250 and 300 mm. PMID:28793423

Yan, Mary R; Parsons, Andrew; Whalley, Gillian A; Kelleher, John; Rush, Elaine C

Maintaining blood glucose within homeostatic limits and eating foods that sup-press hunger and promote satiety have beneficial impacts for health. This study investigated the glycaemic re-sponse and satiety effects of a serving size of a healthier snack bar, branded Nothing Else, that met the required nutrient profiling score criteria for a health claim, in comparison to two top-selling commercial snack bars. In an experimental study, 24 participants aged >=50 years were recruited. On three different days blood glucose concentration was measured twice at baseline and 15, 30, 45, 60, 90 and 120 minutes after consumption of a serving size of each bar. Satiety effects were self-reported hunger, fullness, desire to eat, and amount could eat ratings on visual analogue scales. The incremental area under the blood glucose response curve (iAUC) over two hours for the Nothing Else bar was 30% lower than commercial Bar 2 (p<0.001). At 45 minutes after eating, the Nothing Else bar induced the highest fullness rating and lowest hunger rating among the three snack bars. At two hours, fullness induced by the Nothing Else bar was twice that of Bar 2 (p=0.019), but not different to Bar 1 (p=0.212). The Nothing Else snack bar developed using the nutrient profiling scheme as a guideline, with its high protein and dietary fibre contents, had a lower glycaemic impact and induced a higher subjective satiety than the two commercial snack bars of equal weight.

Gas inflow patterns and nuclear rings in barred galaxies

NASA Astrophysics Data System (ADS)

Shen, Juntai; Li, Zhi

2017-06-01

Nuclear rings, dust lanes, and nuclear spirals are common structures in the inner region of barred galaxies, with their shapes and properties linked to the physical parameters of the galaxies. We use high-resolution hydrodynamical simulations to study gas inflow patterns in barred galaxies, with special attention on the nuclear rings. The location and thickness of nuclear ringsare tightly correlated with galactic properties, such as the bar pattern speed and bulge central density, within certain ranges. We identify the backbone of nuclear rings with a major orbital family of bars. The rings form exactly at the radius where the residual angular momentum of inflowing gas balances the centrifugal force. We propose a new simple method to predict the bar pattern speed for barred galaxies possessing a nuclear ring, without actually doing simulations. We apply this method to some real galaxies and find that our predicted bar pattern speed compare reasonably well with other estimates. Our study may have important implications for using nuclear ringsto measure the parameters of real barred galaxies with detailed gas kinematics. We have also extended current hydrodynamical simulations to model gas features in the Milky Way.

Background Electronic Music Dance Events in nightclubs attract patrons with heavy alcohol/drug use. Public health concerns are raised from risks related to these behaviors. Practices associated with increased risk in these club settings need to be identified. Objectives The relationship between club management practices and biological measures of patrons’ alcohol/drug use is examined. Methods Observational data from 25 events across 6 urban clubs were integrated with survey data (N=738 patrons, 42.8% female) from patrons exiting these events, 2010–2012. Five indicators of club management practices were examined using mixed model regressions: club security, bar crowding, safety signs, serving intoxicated patrons, and isolation. Results Analyses revealed that serving intoxicated patrons and safety signs were related to less substance use. Specifically, serving intoxicated patrons was related to heavy alcohol and drug use at exit, while safety signs were marginally related to less exit drug use. Conclusions/Importance Findings indicate observable measures in nightclubs provide important indicators for alcohol/drug use, suggesting practices to target. Study strengths include the use of biological measures of substance use on a relatively large scale. Limitations and future directions are discussed. PMID:24832721

Visual mining business service using pixel bar charts

NASA Astrophysics Data System (ADS)

Hao, Ming C.; Dayal, Umeshwar; Casati, Fabio

2004-06-01

Basic bar charts have been commonly available, but they only show highly aggregated data. Finding the valuable information hidden in the data is essential to the success of business. We describe a new visualization technique called pixel bar charts, which are derived from regular bar charts. The basic idea of a pixel bar chart is to present all data values directly instead of aggregating them into a few data values. Pixel bar charts provide data distribution and exceptions besides aggregated data. The approach is to represent each data item (e.g. a business transaction) by a single pixel in the bar chart. The attribute of each data item is encoded into the pixel color and can be accessed and drilled down to the detail information as needed. Different color mappings are used to represent multiple attributes. This technique has been prototyped in three business service applications-Business Operation Analysis, Sales Analysis, and Service Level Agreement Analysis at Hewlett Packard Laboratories. Our applications show the wide applicability and usefulness of this new idea.

Behavioural indicators of motives for barroom aggression: implications for preventing bar violence.

2011-09-01

To develop new strategies for preventing violence in high-risk licensed premises, we identify behavioural indicators of apparent motives for aggression in these settings and outline the implications of different motivations for prevention. The four types of motives for aggressive or coercive acts defined by the theory of coercive actions framed the research: gaining compliance, expressing grievances/restoring justice, attaining a favourable social identity and pursuing fun/excitement. Incidents of aggression from the Safer Bars evaluation research were analysed to identify behavioural indicators of each motivation. Compliance-motivated aggression typically takes the form of unwanted social overtures, third party intervention to stop conflicts or staff rule enforcement. Prevention strategies include keeping the aggressor's focus on compliance to avoid provoking grievance and identity motives that are likely to escalate aggression. Grievance motives are typically elicited by perceived wrongdoing and therefore prevention should focus on eliminating sources of grievances and adopting policies/practices to resolve grievances peacefully. Social identity motives are endemic to many drinking establishments especially among male patrons and staff. Prevention involves reducing identity cues in the environment, hiring staff who do not have identity concerns, and training staff to avoid provoking identity concerns. Aggression motivated by fun/excitement often involves low-level aggression where escalation can be prevented by avoiding grievances and attacks on identity. Knowledge of behavioural indicators of motives can be used to enhance staff hiring and training practices, reduce environmental triggers for aggression, and develop policies to reduce motivation for aggression. © 2011 Australasian Professional Society on Alcohol and other Drugs.

Role of Erosion in Shaping Point Bars

NASA Astrophysics Data System (ADS)

Moody, J.; Meade, R.

2012-04-01

A powerful metaphor in fluvial geomorphology has been that depositional features such as point bars (and other floodplain features) constitute the river's historical memory in the form of uniformly thick sedimentary deposits waiting for the geomorphologist to dissect and interpret the past. For the past three decades, along the channel of Powder River (Montana USA) we have documented (with annual cross-sectional surveys and pit trenches) the evolution of the shape of three point bars that were created when an extreme flood in 1978 cut new channels across the necks of two former meander bends and radically shifted the location of a third bend. Subsequent erosion has substantially reshaped, at different time scales, the relic sediment deposits of varying age. At the weekly to monthly time scale (i.e., floods from snowmelt or floods from convective or cyclonic storms), the maximum scour depth was computed (by using a numerical model) at locations spaced 1 m apart across the entire point bar for a couple of the largest floods. The maximum predicted scour is about 0.22 m. At the annual time scale, repeated cross-section topographic surveys (25 during 32 years) indicate that net annual erosion at a single location can be as great as 0.5 m, and that the net erosion is greater than net deposition during 8, 16, and 32% of the years for the three point bars. On average, the median annual net erosion was 21, 36, and 51% of the net deposition. At the decadal time scale, an index of point bar preservation often referred to as completeness was defined for each cross section as the percentage of the initial deposit (older than 10 years) that was still remaining in 2011; computations indicate that 19, 41, and 36% of the initial deposits of sediment were eroded. Initial deposits were not uniform in thickness and often represented thicker pods of sediment connected by thin layers of sediment or even isolated pods at different elevations across the point bar in response to multiple

STELLAR, GAS, AND DARK MATTER CONTENT OF BARRED GALAXIES

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

Cervantes Sodi, Bernardo, E-mail: b.cervantes@crya.unam.mx

We select a sample of galaxies from the Sloan Digital Sky Survey Data Release 7 (SDSS-DR7) where galaxies are classified, through visual inspection, as hosting strong bars, weak bars, or as unbarred galaxies, and make use of H i mass and kinematic information from the Arecibo Legacy Fast ALFA survey catalog, to study the stellar, atomic gas, and dark matter content of barred disk galaxies. We find, in agreement with previous studies, that the bar fraction increases with increasing stellar mass. A similar trend is found with total baryonic mass, although the dependence is not as strong as with stellarmore » mass, due to the contribution of gas. The bar fraction shows a decrease with increasing gas mass fraction. This anticorrelation between the likelihood of a galaxy hosting a bar with the gas richness of the galaxy results from the inhibiting effect the gas has in the formation of bars. We also find that for massive galaxies with stellar masses larger than 10{sup 10} M {sub ⊙}, at fixed stellar mass, the bar fraction decreases with increasing global halo mass (i.e., halo mass measured up to a radius of the order of the H i disk extent).« less

We have mapped the HCN(1-0) emission from two spiral galaxies, NGC 2903 and NGC 3504 to study the gas properties in the bars. The HCN(1-0) emission is detected in the center and along the bar of NGC 2903. The line ratio HCN(1-0)/ 12CO(1-0) ranges from 0.07 to 0.12 with the lowest value in the center. The enhancement of HCN(1-0) emission along the bar indicates a higher fraction of dense molecular gas in the bar than at the center. The mass of dense molecular gas in the center (2.2 × 107 M⊙) is about 6 times lower than that in the bar (1.2 × 108 M⊙). The total star formation rate (SFR) is estimated to be 1.4 M⊙ yr-1, where the SFR at the center is 1.9 times higher than that in the bar. The time scale of consumption of the dense molecular gas in the center is about ~ 3 × 107 yr which is much shorter than that in the bar of about 2 to 10 × 108 yr. The dynamical time scale of inflow of the gas from the bar to the center is shorter than the consumption time scale in the bar, which suggests that the star formation (SF) activity at the center is not deprived of fuel. In the bar, the fraction of dense molecular gas mass relative to the total molecular gas mass is twice as high along the leading edge than along the central axis of the bar. The HCN(1-0) emission has a large velocity dispersion in the bar, which can be attributed partially to the streaming motions indicative of shocks along the bar. In NGC 3504, the HCN(1-0) emission is detected only at the center. The fraction of dense molecular gas mass in the center is about 15%. Comparison of the SFR with the predictions from numerical simulations suggest that NGC 2903 harbors a young type B bar with a strong inflow of gas toward the center whereas NGC 3504 has an older bar and has already passed the phase of inflow of gas toward the center.

Fatigue of reinforcing bars during hydro-demolition

Reinforcing steel fractured during hydro-demolition of a reinforced concrete pier head due to low cycle flexural fatigue from vibration caused by impact of the high pressure water jet on the exposed length of the bars. Research into the fatigue performance of steel reinforcing steel tends to focus on the high cycle axial performance in reinforced concrete members and re-bending behaviour. However with the increasing use of hydro-demolition of concrete structures as part of remediation works care is required to ensure the steel reinforcement exposed to the high pressure jet of water is not going to suffer relatively low cycle flexural damage that may compromise the designed performance of the completed reinforced concrete structure. This paper describes the failure assessment, fatigue analysis, and metallographic examination that was undertaken. It was found that the rib to flank transition radius on the reinforcement steel was small enough to cause a significant stress concentration effect and was the location of fatigue crack growth. A relatively simple analysis using the maximum unrestrained cantilevered bar length and force exerted by the water jet was used to calculate the maximum expected bending moment. This was compared to the bending capacity at initiation of yielding at the rib flank transition accounting for stress concentration effects. This showed that the observed cyclic reversing ductile crack growth and fracture of the H25 bars was consistent with the loading applied. A method is proposed based on these observations to assess suitable limits for unrestrained bar lengths or maximum working offset of the water jet from the point of bar restraint when undertaking hydro-demolition work. The fatigue critical performance requirements of AS/NZS4671 500E bars are also therefore compared with those of BS4449:2005 and PN EN/ISO 15630-1:2011 for comparable 500C bars

Do Low Surface Brightness Galaxies Host Stellar Bars?

With the aim of assessing if low surface brightness galaxies host stellar bars and by studying the dependence of the occurrence of bars as a function of surface brightness, we use the Galaxy Zoo 2 data set to construct a large volume-limited sample of galaxies and then segregate these galaxies as having low or high surface brightness in terms of their central surface brightness. We find that the fraction of low surface brightness galaxies hosting strong bars is systematically lower than that found for high surface brightness galaxies. The dependence of the bar fraction on the central surface brightness is mostly driven by a correlation of the surface brightness with the spin and the gas richness of the galaxies, showing only a minor dependence on the surface brightness. We also find that the length of the bars is strongly dependent on the surface brightness, and although some of this dependence is attributed to the gas content, even at a fixed gas-to-stellar mass ratio, high surface brightness galaxies host longer bars than their low surface brightness counterparts, which we attribute to an anticorrelation of the surface brightness with the spin.

There has been increasing demand to understand the stress-strain response as well as damage and failure mechanisms of materials under impact loading condition. Dynamic tensile characterization has been an efficient approach to acquire satisfactory information of mechanical properties including damage and failure of the materials under investigation. However, in order to obtain valid experimental data, reliable tensile experimental techniques at high strain rates are required. This includes not only precise experimental apparatus but also reliable experimental procedures and comprehensive data interpretation. Kolsky bar, originally developed by Kolsky in 1949 [1] for high-rate compressive characterization of materials, has been extended formore » dynamic tensile testing since 1960 [2]. In comparison to Kolsky compression bar, the experimental design of Kolsky tension bar has been much more diversified, particularly in producing high speed tensile pulses in the bars. Moreover, instead of directly sandwiching the cylindrical specimen between the bars in Kolsky bar compression bar experiments, the specimen must be firmly attached to the bar ends in Kolsky tensile bar experiments. A common method is to thread a dumbbell specimen into the ends of the incident and transmission bars. The relatively complicated striking and specimen gripping systems in Kolsky tension bar techniques often lead to disturbance in stress wave propagation in the bars, requiring appropriate interpretation of experimental data. In this study, we employed a modified Kolsky tension bar, newly developed at Sandia National Laboratories, Livermore, CA, to explore the dynamic tensile response of a 4330-V steel. The design of the new Kolsky tension bar has been presented at 2010 SEM Annual Conference [3]. Figures 1 and 2 show the actual photograph and schematic of the Kolsky tension bar, respectively. As shown in Fig. 2, the gun barrel is directly connected to the incident bar with a coupler. The

Martian Meanders and Scroll-Bars

NASA Image and Video Library

2017-03-01

This is a portion of an inverted fluvial channel in the region of Aeolis/Zephyria Plana, at the Martian equator. Channels become inverted when the sediments filling them become more resistant to erosion than the surrounding material. Here, the most likely process leading to hardening of the channel material is chemical cementation by precipitation of minerals. Once the surrounding material erodes, the channel is left standing as a ridge. The series of curvilinear lineations are ancient scroll-bars, which are features typical of river meanders (bends) in terrestrial fluvial channels. Scroll-bars are series of ridges that result from the continuous lateral migration of a meander. On Earth, they are more common in mature rivers. The presence of scroll bars suggests that the water flow in this channel may have been sustained for a relatively long time. Measuring characteristics of these scroll-bars and meanders may help to estimate the amount of water that once flowed in this channel, aiding our understanding of the history of water on Mars. The map is projected here at a scale of 25 centimeters (9.8 inches) per pixel.

Improved Kolsky tension bar for high-rate tensile characterization of materials

2011-04-01

A new Kolsky tension bar has been re-designed and developed at Sandia National Laboratories, CA. The new design uses the concept that a solid striker is fired to impact an end cap attached to the open end of the gun barrel to generate dynamic tensile loading. The gun barrel here serves as part of the loading device. The incident bar that is connected to the gun barrel and the transmission bar follow the design similar to the Kolsky compression bar. The bar supporting and aligning systems are the same as those in the Kolsky compression bar design described by Song et al (2009 Meas. Sci. Technol. 20 115701). Due to the connection complication among the gun barrel, bars and specimen, stress-wave propagation in the new Kolsky tension bar system is comprehensively analyzed. Based on the stress-wave analysis, the strain gage location on the incident bar needs to be carefully determined. A highly precise laser-beam measurement system is recommended to directly measure the displacement of the incident bar end. Dynamic tensile characterization of a 4330-V steel using this new Kolsky tension bar is presented as an example.

A Review of the Biomechanical Differences Between the High-Bar and Low-Bar Back-Squat.

Glassbrook, DJ, Helms, ER, Brown, SR, and Storey, AG. A review of the biomechanical differences between the high-bar and low-bar back-squat. J Strength Cond Res 31(9): 2618-2634, 2017-The back-squat is a common exercise in strength and conditioning for a variety of sports. It is widely regarded as a fundamental movement to increase and measure lower-body and trunk function, as well as an effective injury rehabilitation exercise. There are typically 2 different bar positions used when performing the back-squat: the traditional "high-bar" back-squat (HBBS) and the "low-bar" back-squat (LBBS). Different movement strategies are used to ensure that the center of mass remains in the base of support for balance during the execution of these lifts. These movement strategies manifest as differences in (a) joint angles, (b) vertical ground reaction forces, and (c) the activity of key muscles. This review showed that the HBBS is characterized by greater knee flexion, lesser hip flexion, a more upright torso, and a deeper squat. The LBBS is characterized by greater hip flexion and, therefore, a greater forward lean. However, there are limited differences in vertical ground reaction forces between the HBBS and LBBS. The LBBS can also be characterized by a greater muscle activity of the erector spinae, adductors, and gluteal muscles, whereas the HBBS can be characterized by greater quadriceps muscle activity. Practitioners seeking to develop the posterior-chain hip musculature (i.e., gluteal, hamstring, and erector muscle groups) may seek to use the LBBS. In comparison, those seeking to replicate movements with a more upright torso and contribution from the quadriceps may rather seek to use the HBBS in training.

A randomised crossover trial of the acute effects of a deep-fried Mars bar or porridge on the cerebral vasculature.

The deep-fried Mars bar has been cited as 'all that is wrong with the high-fat, high-sugar Scottish diet'. We investigated the effect of ingestion of a deep-fried Mars bar or porridge on cerebrovascular reactivity. We hypothesised that deep-fried Mars bar ingestion would impair cerebrovascular reactivity, which is associated with increased risk of ischaemic stroke. Twenty-four fasted volunteers were randomised to receive a deep-fried Mars bar and then porridge (control), or vice-versa. We used transcranial Doppler ultrasound to calculate Breath Holding Index as a surrogate measure of cerebrovascular reactivity. Change in Breath Holding Index post-ingestion was the primary outcome measure. Twenty-four healthy adults (mean (SD) age 21.5 (1.7) years, 14 males) completed the protocol. Deep-fried Mars bar ingestion caused a non-significant reduction in cerebrovascular reactivity relative to control (mean difference in absolute Breath Holding Index after deep-fried Mars bar versus porridge -0.11, p = 0.40). Comparison of the difference between the absolute change in Breath Holding Index between genders demonstrated a significant impairment of cerebrovascular reactivity in males (mean difference women minus men of 0.65, 95% CI 0.30 to 1.00, p = 0.0003). Ingestion of a bolus of sugar and fat caused no overall difference in cerebrovascular reactivity, but there was a modest decrease in males. Impaired cerebrovascular reactivity is associated with increased stroke risk, and therefore deep-fried Mars bar ingestion may acutely contribute to cerebral hypoperfusion in men. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Advanced solid state laser architectures place increasingly demanding requirements on high-brightness, low-cost QCW laser diode pump sources, with custom apertures both for side and end rod pumping configurations. To meet this need, a new series of scaleable pump sources at 808nm and 940nm was developed. The stacks, available in multiple output formats, allow for custom aperture filling by varying both the length and quantity of stacked laser bars. For these products, we developed next-generation laser bars based on improved epitaxial wafer designs delivering power densities of 20W/mm of emission aperture. With >200W of peak QCW power available from a full-length 1cm bar, we have demonstrated power scaling to over 2kW in 10-bar stacks with 55% wall plug efficiency. We also present the design and performance of several stack configurations using full-length and reduced-length (mini) bars that demonstrate the versatility of both the bar and packaging designs. We illustrate how the ROBUST HEAD packaging technology developed at SCD is capable of accommodating variable bar length, pitch and quantity for custom rod pumping geometries. The excellent all-around performance of the stacks is supported by reliability data in line with the previously reported 20 Gshot space-grade qualification of SCD's stacks.

To assess the satiety-promoting effect of a novel viscous fiber-containing nutrition bar, overweight and obese adult subjects with type 2 diabetes (n=99) were randomized into a double blind, crossover study. They were fed a 300kcal lunch consisting of viscous fiber-containing nutrition bars (VF) or commercial nutrition control bars designed for people with diabetes (CH). VF resulted in a 27.1% increase in fullness (p<0.05), a 15.8% decrease in prospective consumption (p<0.001), and a 14.2% decrease in hunger (p<0.001) in the 120-240min post-lunch areas under the curve (AUC) compared to CH, but no differences were observed for nausea or thirst (p>0.05). Similar results were noted for 0-300min AUC values. VF were associated with greater frequencies and intensities of abdominal distention (p<0.001) and flatulence (p<0.001), and greater frequency of stools (p<0.001) compared to CH, but there were no differences in mean or maximum (loosest) stool consistency (p>0.05). Overall, these results suggest that VF could be a useful tool in weight management of type 2 diabetes.

A young person's game: immersion and distancing in bar work.

Previous research indicates that bar workers report high levels of alcohol consumption, but the bar work experience itself has been little studied as a means to understand health threats associated with this job role. The subjective experience and meaning of bar work was explored in this study by interviewing current and ex-bar workers from a district in an Irish city that had a high density of bars and busy tourism industry. A total of 12 participants took part in focus groups (FGs) and seven in individual interviews. Four themes were identified in a thematic analysis. The central depiction of bar work was of an initial immersion in an intensive lifestyle characterised by heavy drinking, with subsequent distancing from the extremes of the lifestyle. The participants affiliated strongly with the bar work occupational identity, which included alcohol use in group scenarios for drinking during work, after work and on time off. The bar work lifestyle was most intense in the 'superpub' environment, characterised by permissive staff drinking norms and reported stress. Although an important identity, bar work was ultimately a transient role. The findings are considered in relation to research on occupation-specific stress and alcohol use, social identity and developmental needs in young adulthood.

Finite Element Simulations to Explore Assumptions in Kolsky Bar Experiments.

The chief purpose of this project has been to develop a set of finite element models that attempt to explore some of the assumptions in the experimental set-up and data reduction of the Kolsky bar experiment. In brief, the Kolsky bar, sometimes referred to as the split Hopkinson pressure bar, is an experimental apparatus used to study the mechanical properties of materials at high strain rates. Kolsky bars can be constructed to conduct experiments in tension or compression, both of which are studied in this paper. The basic operation of the tension Kolsky bar is as follows: compressed air ismore » inserted into the barrel that contains the striker; the striker accelerates towards the left and strikes the left end of the barrel producing a tensile stress wave that propogates first through the barrel and then down the incident bar, into the specimen, and finally the transmission bar. In the compression case, the striker instead travels to the right and impacts the incident bar directly. As the stress wave travels through an interface (e.g., the incident bar to specimen connection), a portion of the pulse is transmitted and the rest reflected. The incident pulse, as well as the transmitted and reflected pulses are picked up by two strain gauges installed on the incident and transmitted bars as shown. By interpreting the data acquired by these strain gauges, the stress/strain behavior of the specimen can be determined.« less

The company they keep: drinking group attitudes and male bar aggression.

The purpose of this study was to assess (a) similarities in self-reported bar-aggression-related attitudes and behaviors among members of young male groups recruited on their way to bars and (b) group-level variables associated with individual members' self-reported likelihood of perpetrating physical bar aggression in the past year, controlling for individual attitudes. Young, male, natural drinking groups recruited on their way to a bar district Thursday, Friday, and Saturday nights (n = 167, 53 groups) completed an online survey that measured whether they had perpetrated physical aggression at a bar in the past year and constructs associated with bar aggression, including attitudes toward male bar aggression and frequency of heavy episodic drinking in the past year. Intraclass correlations and chi-square tests demonstrated significant within-group similarity on bar-aggression-related attitudes and behaviors (ps < .01). Hierarchical linear modeling revealed that group attitudes toward bar aggression were significantly associated with individuals' likelihood of perpetrating physical bar aggression, controlling for individual attitudes (p < .01); however, the link between group heavy episodic drinking and self-reported bar aggression was nonsignificant in the full model. This study suggests that the most important group influence on young men's bar aggression is the attitudes of other group members. These attitudes were associated with group members' likelihood of engaging in bar aggression over and above individuals' own attitudes. A better understanding of how group attitudes and behavior affect the behavior of individual group members is needed to inform aggression-prevention programming.

Dynamics of membrane nanotubes coated with I-BAR

Membrane deformation is a necessary step in a number of cellular processes such as filopodia and invadopodia formation and has been shown to involve membrane shaping proteins containing membrane binding domains from the IRSp53-MIM protein family. In reconstituted membranes the membrane shaping domains can efficiently deform negatively charged membranes into tubules without any other proteins present. Here, we show that the IM domain (also called I-BAR domain) from the protein ABBA, forms semi-flexible nanotubes protruding into Giant Unilamellar lipid Vesicles (GUVs). By simultaneous quantification of tube intensity and tubular shape we find both the diameter and stiffness of the nanotubes. I-BAR decorated tubes were quantified to have a diameter of ~50 nm and exhibit no stiffening relative to protein free tubes of the same diameter. At high protein density the tubes are immobile whereas at lower density the tubes diffuse freely on the surface of the GUV. Bleaching experiments of the fluorescently tagged I-BAR confirmed that the mobility of the tubes correlates with the mobility of the I-BAR on the GUV membrane. Finally, at low density of I-BAR the protein upconcentrates within tubes protruding into the GUVs. This implies that I-BAR exhibits strong preference for negatively curved membranes.

Imitation problems are commonly reported in children with an autism spectrum disorder. However, it has not yet been determined whether imitation problems persist into young adulthood. In this study, we investigated imitation skills of 20 intellectually able young adults with autism spectrum disorder relative to 19 age-matched neurotypical adults. For this purpose, we used a bar-transport task, which evokes the application of the end-state comfort principle. Specifically, we examined whether young adults with autism spectrum disorder imitated the means-end structure of a demonstrator's bar-transport action with and without application of the end-state comfort principle (imitation task). In addition, we examined whether participants spontaneously applied the end-state comfort principle during a similar bar-transport task (free execution task). Results revealed that young adults with autism spectrum disorder imitated the means-end structure of observed actions to the same degree as neurotypical adults ( p = 0.428). In contrast, they applied the end-state comfort principle less often during free executed actions ( p = 0.035). Moreover, during these actions, they were slower to place the bar into the penholder ( p = 0.023), which contributed to the reduced efficiency of their performance. Findings suggest that imitation abilities of young adults with autism spectrum disorder are preserved and that observing others' actions might promote more efficient action planning in this population.

Numerical modeling of the autumnal thermal bar

The autumnal riverine thermal bar of Kamloops Lake has been simulated using atmospheric data from December 1, 2015, to January 4, 2016. The nonhydrostatic 2.5D mathematical model developed takes into account the diurnal variability of the heat fluxes and wind on the lake surface. The average values for shortwave and longwave radiation and latent and sensible heat fluxes were 19.7 W/m2, - 95.9 W/m2, - 11.8 W/m2, and - 32.0 W/m2 respectively. Analysis of the wind regime data showed prevailing easterly winds and maximum speed of 11 m/s on the 8th and 19th days. Numerical experiments with different boundary conditions at the lake surface were conducted to evaluate effects of variable heat flux and wind stress. The results of modeling demonstrated that the variable heat flux affects the process of thermal bar evolution, especially during the lengthy night cooling. However, the wind had the greatest impact on the behavior of the autumnal thermal bar: The easterly winds contributed to an earlier appearance of the thermal bar, but the strong winds generating the intensive circulations (the velocity of the upper lake flow increased to 6 cm/s) may destroy the thermal bar front.

Gaseous Vortices in Barred Spiral Galaxies

1995-01-01

During the course of examining many two-dimensional, as well as a smaller sample of three-dimensional, models of gas flows in barred spiral galaxies, we have been impressed by the ubiquitous presence fo vortex pairs, oriented roughly perpendicular to their bars, with one vortex on each side. The vortices are obvious only when viewed in the bar frame, and the centers of their velocity fields usually are near Lagrangian points L(sub 4,5). In all models that we have studied, the vortices form on essentially the same time scale as that for the development of gaseous spiral arms, typically two bar rotations. Usually the corotation radius, r(sub c), lies slightly beyond the end of the bar. Depending upon the mass distributions of the various components, gas spirals either into, or out of, the vortices: In the former case, the vortices become regions of high density, whereas the opposite is true if the gas spirals out of a vortex. The models described in this paper have low-density vortices, as do most of the models we have studied. Moreover, usually the vortex centers lie approximately within +/- 15 deg of L(sub 4,5). In the stellar dynamic limit, when pressure and viscous forces are absent, short-period orbits exist, centered on L(sub 4,5). These orbits need not cross and therefore their morphology is that of gas streamlines, that is, vortices. We believe that the gas vortices in our models are hydrodynamic analogues of closed, short-period, libration orbits centered on L(sub 4,5).

An investigation of the tri-bar gripping system on isometric muscular endurance.

PubMed

Drury, Daniel G; Faggiono, Heath; Stuempfle, Kristin J

2004-11-01

Recently, a new product called the Tri-Bar has been introduced as an alternative to the standard round weightlifting bar. The Tri-Bar has the same weight, length, and circumference as a standard weightlifting bar and differs only in that the shape of the bar is formed like a triangle with rounded edges. Theoretically, the shape of the bar will enhance gripping comfort and increase muscular endurance. We studied 32 moderately trained males who were free from upper-body injury or limitation. Each participant completed 4 visits to the lab as part of 2 separate investigations. The first investigation was a comparison of straight-arm hang times while grasping a standard Olympic bar or a Tri-Bar attached to the top of a power rack. The second investigation involved grasping a standard revolving cable handle or a Tri-Bar revolving handle attached to a weight equal to half the subject's body weight. In both investigations, time was used as a measure of isometric muscular endurance. Differences were determined using a dependent t-test, and a level of significance was set at p < 0.05. Mean hang times were significantly longer when the men hung from the Tri-Bar (107.6 seconds) versus the standard bar (95.4 seconds) (p = 0.015). Conversely, in the investigation using the revolving handles, the round bar produced longer grasping times (71.5 seconds) than the Tri-Bar (62.6 seconds) (p = 0.000). The results of this investigation indicate that a fixed and stable Tri-Bar may help to increase hang time, but a Tri-Bar free to rotate within the grasp may decrease grasping time in comparison to a standard round handle. With regard to exercises that require isometric grasping, the Tri-Bar may be an effective alternative to the standard bar for increasing isometric grasping endurance.

Bar and clip attachments significantly improve the level of satisfaction of denture-wearing patients by enhancing the retention and stability of the prosthesis. These attachments have been most commonly used for connecting the prosthesis to implants, but they can be effectively used to retain tooth-supported prosthesis as well. The primary functions of bar attachments are splinting the abutments together, even distribution of forces to the abutments and supporting areas, guiding the prosthesis into place, improving the retention, stability, support and comfort of the patient. The primary requirement for the use of bar attachments is the availability of sufficient vertical and buccolingual space for the proper placement of the bar, sleeves, teeth arrangement and sufficient thickness of acrylic denture base to minimise incidence of denture fracture in the area of bar assembly.

Study of aging and embrittlement of microalloyed steel bars

NASA Astrophysics Data System (ADS)

Campillo, B.; Perez, R.; Martinez, L.

1996-10-01

The aging of hooks, anchors, and other bent reinforcing steel bars in concrete structures are considered in modern international standards. Rebend test procedures have been designed in order to predict the aging embrittlement susceptibility by submerging bent reinforcing bar specimens in boiling water. Subsequently the bars are rebent or straightened in order to determine the loss of ductility or embrittlement of the aged material. The present work considers the influence of carbon, sulfur, and niobium on the performance of reinforcing bars in rebend tests of 300 heats of microalloyed steel bars with a variety of compositions. The microstructural evidence and the statistical results clearly indicate the strong influence of carbon and sulfur on rebend failure, while niobium-rich precipitates contribute to the hardening of the ferrite grains during aging.

2016-10-01

The aim of the current study was to assess correlates of intoxication in licensed venues in Australia. Covert observations of licensed venues and venue patron in night-time entertainment districts of five Australian cities were conducted. In total, 828 unique cross-sectional observations were completed across 62 bars, nightclubs, and large mainstream pubs. Venues were selected from the main entertainment district of smaller cities and the busiest entertainment districts of larger cities. Outcomes were the estimated percentage of patrons showing any signs of alcohol intoxication and the overall level of intoxication ('high' versus 'none to medium'). Seven predictors of patron intoxication were examined: hour of observation; estimated percentage of male patrons; estimated percentage of patrons <25 years old; venue crowding; presence of observable alcohol promotions; type of alcoholic beverage consumed by the majority of patrons; and, venue type. Time of night (coefficient=11.71, p<.001; OR=9.61, p<.001), percentage of patrons aged <25 (coefficient=0.14, p<.001; OR=1.01, p=.031), and venue crowding (coefficient=4.40, p<.001; OR=1.39, p=.009) had significant positive associations with both signs of intoxication and high levels of intoxication. Nightclubs had a lower percentage of signs of intoxication compared to pubs (coefficient=-10.73, p=.021). Increased percentage of male patrons was associated with increased odds of high-level intoxication (OR=1.05, p=.020). Time of night and proportion of younger patrons had a strong association with patron intoxication adding further support for the strong body of evidence that ceasing service of alcohol earlier in the evening will reduce intoxication levels.

Why and How the Tobacco Industry Sells Cigarettes to Young Adults: Evidence From Industry Documents

PubMed Central

Ling, Pamela M.; Glantz, Stanton A.

2002-01-01

Objectives. To improve tobacco control campaigns, we analyzed tobacco industry strategies that encourage young adults (aged 18 to 24) to smoke. Methods. Initial searches of tobacco industry documents with keywords (e.g., “young adult”) were extended by using names, locations, and dates. Results. Approximately 200 relevant documents were found. Transitions from experimentation to addiction, with adult levels of cigarette consumption, may take years. Tobacco marketing solidifies addiction among young adults. Cigarette advertisements encourage regular smoking and increased consumption by integrating smoking into activities and places where young adults' lives change (e.g., leaving home, college, jobs, the military, bars). Conclusions. Tobacco control efforts should include both adults and youths. Life changes are also opportunities to stop occasional smokers' progress to addiction. Clean air policies in workplaces, the military, bars, colleges, and homes can combat tobacco marketing. (Am J Public Health. 2002;92:908–916) PMID:12036776

Binge Drinking Associations with Patrons' Risk Behaviors and Alcohol Effects after Leaving a Nightclub: Sex Differences in the "Balada com Ciência" Portal Survey Study in Brazil.

Sanchez, Zila M; Ribeiro, Karen J; Wagner, Gabriela A

2015-01-01

The purpose of the present study was to investigate the potential associations of binge drinking detected at the exit of nightclubs and risk behaviors and alcohol effects just after leaving the venue in a representative sample of Brazilian nightclub patrons according to sex. For this purpose, a portal survey study called Balada com Ciência was conducted in 2013 in the megacity of São Paulo, Brazil, using a two-stage cluster sampling survey design. Individual-level data were collected in 2422 subjects at the entrance and 1822 subjects at the exit of 31 nightclubs, and breath alcohol concentration (BrAC) was measured using a breathalyzer. The following day, 1222 patrons answered an online follow-up survey that included questions about risk behaviors and alcohol effects practiced just after leaving the nightclub. Weighted logistic regressions were used to analyze binge drinking associated with risk behaviors by sex. For both sexes, the most prevalent risk behaviors practiced after leaving a nightclub were drinking and driving (men=27.9%; women=20.4%), the use of illicit drugs (men=15.8%; women=9.4%) and risky sexual behavior (men=11.4%; women=6.8%). The practice of binge drinking increased the behavior of illicit drug use after leaving the nightclub by 2.54 times [95% CI: 1.26-5.09] among men who drank and increased the risk of an episode of new alcohol use by 5.80 times [95% CI: 1.50-22.44] among women who drank. Alcoholic blackouts were more prevalent among men [OR=8.92; 95% CI: 3.83-20.80] and women [OR= 5.31; 95% CI: 1.68-16.84] whose BrAC was equivalent to binge drinking compared with patrons with a lower BrAC. Public policies aiming to reduce patrons' BrAC at the exit of nightclubs, such as staff training in responsible beverage service and legislation to prevent alcohol sales to drunk individuals, would be useful to protect patrons from the risk behaviors associated with binge drinking in nightclubs.

Print media coverage of California's smokefree bar law

PubMed Central

Magzamen, S.; Charlesworth, A.; Glantz, S.

2001-01-01

OBJECTIVE—To assess the print media coverage of California's smokefree bar law in the state of California.
DESIGN—Content analysis of newspaper, trade journal, and magazine items.
SUBJECTS—Items regarding the smokefree bar law published seven months before and one year following the implementation of the smokefree bar law (June 1997 to December 1998). Items consisted of news articles (n = 446), opinion editorials (n = 31), editorials (n = 104), letters to the editor (n = 240), and cartoons (n = 10).
MAIN OUTCOME MEASURES—Number and timing of publication of items, presence of tobacco industry arguments or public health arguments regarding law, positive, negative, and neutral views of opinion items published.
RESULTS—53% of items published concerning the smokefree bar law were news articles, 47% were opinion items. 45% of items regarding the smokefree bar law were published during the first month of implementation. The tobacco industry dominated coverage in most categories (economics, choice, enforcement, ventilation, legislation, individual quotes), except for categories public health used the most frequently (government role, tactics, organisational quotes). Anti-law editorials and letters to the editor were published more than pro-law editorials and letters. Region of the state, paper size, presence of local clean indoor air legislation, and voting on tobacco related ballot initiatives did not have an impact on the presence of opinion items.
CONCLUSIONS—The tobacco industry succeeded in obtaining more coverage of the smokefree bar law, both in news items and opinion items. The tobacco industry used historical arguments of restricting freedom of choice and economic ramifications in fighting the smokefree bar law, while public health groups focused on the worker protection issue, and exposed tobacco industry tactics. Despite the skewed coverage, public health groups obtained adequate attention to their arguments to keep the law in

Delivering customized apps, multimedia and NASA data to libraries and their patrons

2017-12-01

With funding through NASA's Science Mission Directorate, the NASA @ My Library project has been working with the public library community to enhance the STEM literacy of library patrons throughout the nation. One element of the project is to disseminate a variety of materials to 75 partner libraries in order to support their implementation of hands-on, NASA related STEM activities for their patrons. These materials range from very low tech (UV beads) to high tech (a 4.5" Orion Dobsonian telescope), and include an 8" tablet. This tablet provides us with a wide range of possibilities for delivering NASA content. Besides NASA multimedia and real-time spacecraft data, the tablets can be used for interactive activities, including public apps as well as apps specifically designed for this program, such as a green screen app that incorporates NASA imagery as part of a larger storytelling activity. The tablets also include a full sensor suite (magnetometer, light sensor, accelerometer, etc.), allowing us to develop library activities that use the tablet as a measuring device - detecting magnetism in a "Meteorite or Wrong" activity, or using the light sensor as a transit device. The tablet is centrally managed and includes a "kiosk mode", allowing the libraries to use it in either a locked down or conventional mode. The management system also allows us to create a curated collection of apps and multimedia, push out updated software, and collect analytics data on how the tablet is being used. In this presentation we will discuss the library pre-survey that guided our tablet development process, as well as our lessons learned to date, including the practicality and effectiveness of deploying tablets at this scale, their ability to support NASA specific STEM efforts, and what we have learned about library usage.

Bar formation as driver of gas inflows in isolated disc galaxies

NASA Astrophysics Data System (ADS)

Fanali, R.; Dotti, M.; Fiacconi, D.; Haardt, F.

2015-12-01

Stellar bars are a common feature in massive disc galaxies. On a theoretical ground, the response of gas to a bar is generally thought to cause nuclear starbursts and, possibly, AGN activity once the perturbed gas reaches the central supermassive black hole. By means of high-resolution numerical simulations, we detail the purely dynamical effects that a forming bar exerts on the gas of an isolated disc galaxy. The galaxy is initially unstable to the formation of non-axisymmetric structures, and within ˜1 Gyr it develops spiral arms that eventually evolve into a central stellar bar on kpc scale. A first major episode of gas inflow occurs during the formation of the spiral arms while at later times, when the stellar bar is establishing, a low-density region is carved between the bar corotational and inner Lindblad resonance radii. The development of such `dead zone' inhibits further massive gas inflows. Indeed, the gas inflow reaches its maximum during the relatively fast bar-formation phase and not, as often assumed, when the bar is fully formed. We conclude that the low efficiency of long-lived, evolved bars in driving gas towards galactic nuclei is the reason why observational studies have failed to establish an indisputable link between bars and AGNs. On the other hand, the high efficiency in driving strong gas inflows of the intrinsically transient process of bar formation suggests that the importance of bars as drivers of AGN activity in disc galaxies has been overlooked so far. We finally prove that our conclusions are robust against different numerical implementations of the hydrodynamics routinely used in galaxy evolution studies.

Study of the production of pairs of top quarks in association with a Higgs boson is one of the primary goals of the Large Hadron Collider over the next decade, as measurements of this process may help us to understand whether the uniquely large mass of the top quark plays a special role in electroweak symmetry breaking. Higgs bosons decay predominantly to bmore » $$\\bar{_b}$$, yielding signatures for the signal that are similar to t$$\\bar{_t}$$ + jets with heavy flavor. Though particularly challenging to study due to the similar kinematics between signal and background events, such final states (t$$\\bar{_t}$$b$$\\bar{b}$$) are an important channel for studying the top quark Yukawa coupling. This paper presents a systematic study of machine learning (ML) methods for detecting t$$\\bar{_t}$$h in the h → b$$\\bar{b}$$ decay channel. Among the seven ML methods tested, we show that neural network models outperform alternative methods. In addition, two neural models used in this paper outperform NeuroBayes, one of the standard algorithms used in current particle physics experiments. We further study the effectiveness of ML algorithms by investigating the impact of feature set and data size, as well as the depth of the networks for neural models. We demonstrate that an extended feature set leads to improvement of performance over basic features. Furthermore, the availability of large samples for training is found to be important for improving the performance of the techniques. For the features and the data set studied here, neural networks of more layers deliver comparable performance to their simpler counterparts.« less

Partial entrainment of gravel bars during floods

USGS Publications Warehouse

Konrad, Christopher P.; Booth, Derek B.; Burges, Stephen J.; Montgomery, David R.

2002-01-01

Spatial patterns of bed material entrainment by floods were documented at seven gravel bars using arrays of metal washers (bed tags) placed in the streambed. The observed patterns were used to test a general stochastic model that bed material entrainment is a spatially independent, random process where the probability of entrainment is uniform over a gravel bar and a function of the peak dimensionless shear stress τ0* of the flood. The fraction of tags missing from a gravel bar during a flood, or partial entrainment, had an approximately normal distribution with respect to τ0* with a mean value (50% of the tags entrained) of 0.085 and standard deviation of 0.022 (root‐mean‐square error of 0.09). Variation in partial entrainment for a given τ0* demonstrated the effects of flow conditioning on bed strength, with lower values of partial entrainment after intermediate magnitude floods (0.065 < τ0*< 0.08) than after higher magnitude floods. Although the probability of bed material entrainment was approximately uniform over a gravel bar during individual floods and independent from flood to flood, regions of preferential stability and instability emerged at some bars over the course of a wet season. Deviations from spatially uniform and independent bed material entrainment were most pronounced for reaches with varied flow and in consecutive floods with small to intermediate magnitudes.

Dynamic tensile characterization of a 4330-V steel with kolsky bar techniques.

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

Song, Bo; Antoun, Bonnie R.; Connelly, Kevin

2010-09-01

There has been increasing demand to understand the stress-strain response as well as damage and failure mechanisms of materials under impact loading condition. Dynamic tensile characterization has been an efficient approach to acquire satisfactory information of mechanical properties including damage and failure of the materials under investigation. However, in order to obtain valid experimental data, reliable tensile experimental techniques at high strain rates are required. This includes not only precise experimental apparatus but also reliable experimental procedures and comprehensive data interpretation. Kolsky bar, originally developed by Kolsky in 1949 [1] for high-rate compressive characterization of materials, has been extended formore » dynamic tensile testing since 1960 [2]. In comparison to Kolsky compression bar, the experimental design of Kolsky tension bar has been much more diversified, particularly in producing high speed tensile pulses in the bars. Moreover, instead of directly sandwiching the cylindrical specimen between the bars in Kolsky bar compression bar experiments, the specimen must be firmly attached to the bar ends in Kolsky tensile bar experiments. A common method is to thread a dumbbell specimen into the ends of the incident and transmission bars. The relatively complicated striking and specimen gripping systems in Kolsky tension bar techniques often lead to disturbance in stress wave propagation in the bars, requiring appropriate interpretation of experimental data. In this study, we employed a modified Kolsky tension bar, newly developed at Sandia National Laboratories, Livermore, CA, to explore the dynamic tensile response of a 4330-V steel. The design of the new Kolsky tension bar has been presented at 2010 SEM Annual Conference [3]. Figures 1 and 2 show the actual photograph and schematic of the Kolsky tension bar, respectively. As shown in Fig. 2, the gun barrel is directly connected to the incident bar with a coupler. The

Membrane curvature and its generation by BAR proteins

PubMed Central

Mim, Carsten; Unger, Vinzenz M

2012-01-01

Membranes are flexible barriers that surround the cell and its compartments. To execute vital functions such as locomotion or receptor turnover, cells need to control the shapes of their membranes. In part, this control is achieved through membrane-bending proteins, such as the bin/amphiphysin/rvs domain (BAR) proteins. Many open questions remain about the mechanisms by which membrane-bending proteins function. Addressing this shortfall, recent structures of BAR protein:membrane complexes support existing mechanistic models, but also produced novel insights into how BAR-domain proteins sense, stabilize and generate curvature. Here we review these recent findings, focusing on how BAR proteins interact with the membrane, and how the resulting scaffold structures might aid the recruitment of other proteins to the sites where membranes are bent.

A novel fiber composite ingredient incorporated into a beverage and bar blunts postprandial serum glucose and insulin responses: a randomized controlled trial.

O'Connor, Lauren E; Campbell, Wayne W

2016-03-01

Previous research supports that consumption of resistant starch and guar gum independently influences insulin-mediated glucose responses to meals. This research assessed a novel co-processed fiber composite (FC) ingredient comprising whole-grain high-amylose maize flour and viscous guar gum on glucose and insulin responses to co-consumed and subsequent meals in humans. It was hypothesized that a smoothie-type beverage or a cold-pressed snack bar containing the FC would blunt and sustain serum glucose and insulin postprandial responses compared with maltodextrin (MD). The beverage and bar were assessed in 2 separate studies using identical protocols. Young, nondiabetic, nonobese adults participated in 2 testing days (randomized crossover design) separated by at least 1 week for both food forms. On each testing day, the FC or MD product was consumed with a low-fiber standardized breakfast followed by a low-fiber standardized lunch (with no FC or MD) 4 hours later. Blood samples were collected at baseline and incrementally throughout the 8-hour testing day. One-tailed paired t tests were performed to compare treatment areas under the curve, and a doubly repeated-measures analysis of variance was performed to compare treatment responses at individual time points (P< .05, Bonferroni corrected). The FC blunted the postprandial glucose and insulin responses compared with MD, including a robust glucose and insulin response reduction after breakfast and a continued modest glycemic second-meal reduction after lunch in both the beverage and the bar. These findings support the use of this novel whole-grain FC ingredient in a beverage or bar for insulin-mediated glucose control in young healthy adults. Copyright © 2016 Elsevier Inc.

The panic bars (and associated linkages and electrical circuitry) that are defined in this document are a machine operator-actuated control for the emergency deenergization of the tram motors on self-propelled, electric and diesel face equipment, including haulage equipment such as shuttle cars. There are nine basic types of panic bars (and several variations) that are recommended in this document, but all of the panic bars are characteristically of the ''fire door'' type that is frequently encountered on outside exit doors of many public and some commercial buildings. It is also the intent of the following panic bar designs that, whenmore » emergency brakes are added to the face equipment machinery for which they are required, that they be designed and hooked up so that actuation of the panic bar will result in automatic application of the emergency brakes (immediately following the deenergization of the tram motors).

The BAR Domain Proteins: Molding Membranes in Fission, Fusion, and Phagy

PubMed Central

Ren, Gang; Vajjhala, Parimala; Lee, Janet S.; Winsor, Barbara; Munn, Alan L.

2006-01-01

The Bin1/amphiphysin/Rvs167 (BAR) domain proteins are a ubiquitous protein family. Genes encoding members of this family have not yet been found in the genomes of prokaryotes, but within eukaryotes, BAR domain proteins are found universally from unicellular eukaryotes such as yeast through to plants, insects, and vertebrates. BAR domain proteins share an N-terminal BAR domain with a high propensity to adopt α-helical structure and engage in coiled-coil interactions with other proteins. BAR domain proteins are implicated in processes as fundamental and diverse as fission of synaptic vesicles, cell polarity, endocytosis, regulation of the actin cytoskeleton, transcriptional repression, cell-cell fusion, signal transduction, apoptosis, secretory vesicle fusion, excitation-contraction coupling, learning and memory, tissue differentiation, ion flux across membranes, and tumor suppression. What has been lacking is a molecular understanding of the role of the BAR domain protein in each process. The three-dimensional structure of the BAR domain has now been determined and valuable insight has been gained in understanding the interactions of BAR domains with membranes. The cellular roles of BAR domain proteins, characterized over the past decade in cells as distinct as yeasts, neurons, and myocytes, can now be understood in terms of a fundamental molecular function of all BAR domain proteins: to sense membrane curvature, to bind GTPases, and to mold a diversity of cellular membranes.

The Role of 2D Circulation in Sand Bar Migration

NASA Astrophysics Data System (ADS)

Splinter, K. D.; Holman, R. A.; Plant, N. G.; Holland, K. T.

2006-12-01

Models of bar dynamics typically involve moments of the cross-shore flow, with offshore movement associated with the strong offshore directed undertow and onshore migration related to wave asymmetry and skewness [Gallagher, et al., 1998]. Based on these hypotheses, models and laboratory studies have used the alongshore-mean bar position and alongshore-uniform wave conditions (a 1DH approach) to study bar response to varying wave conditions. Commonly, cases of offshore migration were reproduced with reasonable accuracy, but predictions of onshore migration were less successful. However, examination of time-exposure images of waves show that during periods of offshore migration, bars tend to be alongshore uniform and move rapidly offshore, but during onshore migration, sand bars are rarely straight, instead becoming very sinuous, violating the 1DH approach. We hypothesize that under milder wave conditions, the 2DH circulation associated with this alongshore-variable morphology is, in fact, largely responsible for increased onshore net sand transport and the resulting onshore bar movement. We extend the work of Plant et al. [in review] that relates bar position, sinuosity, and wave forcing within a dynamical feedback model. The model consists of coupled differential equations that govern the rates of change of cross-shore position and horizontal sinuosity as a function of the current cross-shore position and sinuosity and a proxy for wave forcing. Using a short data set from Duck, NC, they solve for the unknown coupling coefficients by doing a least-squares fit. They find that the coefficients for the self-interaction terms have a negative sign, indicating the overall system is stable. The coefficients of the cross-interaction terms (the effect of sinuosity on rate of change of bar position and visa versa), however, are non-zero and have opposite signs indicating the systems are coupled and stability is not affected by these terms. We expand this study, relating bar

This invention relates to an attachment for a sine bar which can be used to perform measurements during lathe operations or other types of machining operations. The attachment can be used for setting precision angles on vises, dividing heads, rotary tables and angle plates. It can also be used in the inspection of machined parts, when close tolerances are required, and in the layout of precision hardware. The novelty of the invention is believed to reside in a specific versatile sine bar attachment for measuring a variety of angles on a number of different types of equipment.

Based on fractal theory and damage mechanics, the aim of this paper is to describe the monofractal and multifractal characteristics of corrosion morphology and develop a new approach to characterize the nonuniform corrosion degree of reinforcing bars. The relationship between fractal parameters and tensile strength of reinforcing bars are discussed. The results showed that corrosion mass loss ratio of a bar cannot accurately reflect the damage degree of the bar. The corrosion morphology of reinforcing bars exhibits both monofractal and multifractal features. The fractal dimension and the tensile strength of corroded steel bars exhibit a power function relationship, while the width of multifractal spectrum and tensile strength of corroded steel bars exhibit a linear relationship. By comparison, using width of multifractal spectrum as multifractal damage variable not only reflects the distribution of corrosion damage in reinforcing bars, but also reveals the influence of nonuniform corrosion on the mechanical properties of reinforcing bars. The present research provides a new approach for the establishment of corrosion damage constitutive models of reinforcing bars. PMID:22238682

DAMPING OF THE MILKY WAY BAR BY MANIFOLD-DRIVEN SPIRALS

2016-10-10

We describe a new phenomenon of “bar damping” that may have played an important role in shaping the Milky Way bar and bulge as well as its spiral structure. We use a collisionless N -body simulation of a Milky Way–like galaxy initially composed of a dark matter halo and an exponential disk with a Toomre parameter slightly above unity. In this configuration, dominated by the disk in the center, a bar forms relatively quickly, after 1 Gyr of evolution. This is immediately followed by the formation of two manifold-driven spiral arms and the outflow of stars that modifies the potentialmore » in the vicinity of the bar, apparently shifting the position of the L {sub 1}/ L {sub 2} Lagrange points. This modification leads to the shortening of the bar and the creation of a next generation of manifold-driven spiral arms at a smaller radius. The process repeats itself a few times over the next 0.5 Gyr resulting in further substantial weakening and shortening of the bar. The time when the damping comes to an end coincides with the first buckling episode in the bar that rebuilds the orbital structure so that no more new spiral arms are formed. The morphology of the bar and the spiral structure at this time show remarkable similarity to the present properties of the Milky Way. Later on, the bar starts to grow rather steadily again, weakened only by subsequent buckling episodes occurring at more distant parts of the disk.« less

Stress-strain relationship of high-strength steel (HSS) reinforcing bars

2018-05-01

The introduction of High-Strength Steel (HSS) reinforcing bars in reinforced concrete members has gained much attention in recent years and led to many advantages such as construction timesaving. It is also more economical since it can reduce the amount of reinforcing steel bars used in concrete members which in turn alleviates the congestion of reinforcement. Up to present, the building codes, e.g. American Concrete Institute (ACI) 318M-14 and Standard National Indonesia (SNI) 2847:2013, still restrict the use of higher-strength steel reinforcing bars for concrete design up to Grade 420 MPa due to the possible suspected brittle behavior of concrete members. This paper evaluates the characteristics of stress-strain relationships of HSS bars if they are comparable to the characteristics of those of Grade 420 MPa. To achieve the objective of the study, a series of steel bars from various grades (420, 550, 650, and 700 MPa) was selected. Tensile tests of these steel samples were conducted under displacement-controlled mode to capture the complete stress-strain curves and particularly the post-yield response of the steel bars. The results indicate that all the steel bars tested had the actual yield strengths greater than the corresponding specified values. The stress-strain curves of HSS reinforcing bars (Grade 550, 650, and 700 MPa) performed slightly different characteristics with those of Grade 420 MPa.

Defining the formative discharge for alternate bars in alluvial rivers

NASA Astrophysics Data System (ADS)

Redolfi, M.; Carlin, M.; Tubino, M.; Adami, L.; Zolezzi, G.

2017-12-01

We investigate the properties of alternate bars in long straight reaches of channelized streams subject to an unsteady, irregular flow regime. To this aim we propose a novel integration of a statistical approach with the analytical perturbation model of Tubino (1991) which predicts the evolution of bar properties (namely amplitude and wavelength) as consequence of a flood. The outcomes of our integrated modelling approach are probability distribution of the bar properties, which depend essentially on two ingredients: (i) the statistical properties of the flow regime (duration, frequency and magnitude of the flood events, and (ii) the reach-averaged hydro-geomorphic characteristics of the channel (bed material, channel gradient and width). This allows to define a "bar-forming" discharge value as the flow value which would reproduce the most likely bar properties in a river reach under unsteady flow. Alternate bars are often migrating downstream and growing or declining during flood events. The timescale of bar growth and migration is often comparable with the duration of the floods: consequently, bar properties such as height and wavelength do not respond instantaneously to discharge variations (i.e. quasi-equilibrium response) but may depend on previous flood events. Theoretical results are compared with observations in three Alpine, channelized gravel bed rivers with encouraging outcomes.

The purpose of this study was to investigate the fit of cast alloy overdenture and laser-welded titanium-alloy bars by measuring induced strain upon tightening of the bars on a master cast as well as a function of screw tightening sequence. Four implant analogs were secured into Type IV dental stone to simulate a mandibular edentulous patient cast, and two groups of four overdenture bars were fabricated. Group I was four cast alloy bars and Group II was four laser-welded titanium bars. The cast alloy bars included Au-Ag-Pd, Pd-Ag-Au, Au-Ag-Cu-Pd, and Ag-Pd-Cu-Au, while the laser-welded bars were all Ti-Al-V alloy. Bars were made from the same master cast, were torqued into place, and the total strain in the bars was measured through five strain gauges bonded to the bar between the implants. Each bar was placed and torqued 27 times to 30 Ncm per screw using three tightening sequences. Data were processed through a strain amplifier and analyzed by computer using StrainSmart software. Data were analyzed by ANOVA and Tukey's post hoc test. Significant differences were found between alloy types. Laser-welded titanium bars tended to have lower strains than corresponding cast bars, although the Au-Ag-Pd bar was not significantly different. The magnitudes of total strain were the least when first tightening the ends of the bar. The passivity of implant overdenture bars was evaluated using total strain of the bar when tightening. Selecting a high modulus of elasticity cast alloy or use of laser-welded bar design resulted in the lowest average strain magnitudes. While the effect of screw tightening sequence was minimal, tightening the distal ends first demonstrated the lowest strain, and hence the best passivity.

Endophilin-A1 BAR domain interaction with arachidonyl CoA.

Petoukhov, Maxim V; Weissenhorn, Winfried; Svergun, Dmitri I

2014-01-01

Endophilin-A1 belongs to the family of BAR domain containing proteins that catalyze membrane remodeling processes via sensing, inducing and stabilizing membrane curvature. We show that the BAR domain of endophilin-A1 binds arachidonic acid and molds its coenzyme A (CoA) activated form, arachidonyl-CoA into a defined structure. We studied low resolution structures of endophilin-A1-BAR and its complex with arachidonyl-CoA in solution using synchrotron small-angle X-ray scattering (SAXS). The free endophilin-A1-BAR domain is shown to be dimeric at lower concentrations but builds tetramers and higher order complexes with increasing concentrations. Extensive titration SAXS studies revealed that the BAR domain produces a homogenous complex with the lipid micelles. The structural model of the complexes revealed two arachidonyl-CoA micelles bound to the distal arms of an endophilin-A1-BAR dimer. Intriguingly, the radius of the bound micelles significantly decreases compared to that of the free micelles, and this structural result may provide hints on the potential biological relevance of the endophilin-A1-BAR interaction with arachidonyl CoA.

This study explores whether associations between consuming alcohol in bars and alcohol-related harms are consistent across countries and whether country-level characteristics modify associations. We hypothesized that genderedness of bar drinking modifies associations, such that odds of harms associated with bar drinking increase more rapidly in predominantly male bar-drinking countries. Multilevel analysis was used to analyze survey data from 21 countries representing five continents from Gender, Alcohol, and Culture: An International Study (GENACIS). Bar frequency was positively associated with harms overall. Relationships between bar frequency and harms varied across country. Genderedness modified associations between bar frequency and odds of fights, marriage/relationship harms, and work harms. Findings were significant only for men. Contrary to our hypothesis, odds of harms associated with bar drinking increased less rapidly in countries where bar drinking is predominantly male. This suggests predominantly male bar drinking cultures may be protective for males who more frequently drink in bars. PMID:23710158

Subsurface flow in lowland river gravel bars

Geomorphic and hydraulic processes, which form gravel bars in large lowland rivers, have distinctive characteristics that control the magnitude and spatial patterns of infiltration and exfiltration between rivers and their immediate subsurface environments. We present a bedform-infiltration relation together with a set of field measurements along two reaches of the San Joaquin River, CA to illustrate the conditions required for infiltration and exfiltration of flow between a stream and its undulating bed, and a numerical model to investigate the factors that affect paths and residence times of flow through barforms at different discharges. It is shown that asymmetry of bar morphology is a first-order control on the extent and location of infiltration, which would otherwise produce equal areas of infiltration and exfiltration under the assumption of sinusoidal bedforms. Hydraulic conductivity varies by orders of magnitude due to fine sediment accumulation and downstream coarsening related to the process of bar evolution. This systematic variability not only controls the magnitude of infiltration, but also the residence time of flow through the bed. The lowest hydraulic conductivity along the reach occurred where the difference between the topographic gradient and the water-surface gradient is at a maximum and thus where infiltration would be greatest into a homogeneous bar, indicating the importance of managing sand supply to maintain the ventilation and flow through salmon spawning riffles. Numerical simulations corroborate our interpretation that infiltration patterns and rates are controlled by distinctive features of bar morphology.

Most adults do not walk enough to obtain health benefits. Pedometers have been successfully utilized to motivate and increase walking. Given that libraries are a place where community members seek health resources, they are a logical setting for increasing community accessibility to pedometers. The purpose was to examine the feasibility of lending pedometers to library patrons to increase walking. In five Canadian public libraries, 90 pedometers were made available for 6 months. A total of 41 library patrons (33 women, 8 men, age range 18 to 65 or older) completed a survey about their walking patterns and pedometer use. More than 330 loans were made. Chisquare analysis found significant associations between walking and motivation to walk more (p < .05), walking and goal setting (p < .05), and motivation to walk more and setting a walking goal (p < .001). Results provide preliminary evidence that lending pedometers through local libraries is an effective, low-cost approach to enhance walking in community members.

To test optimal graphic risk communication formats for presenting small probabilities using graphics with a denominator of 1000 to adults with lower education and literacy. A randomized experimental study, which took place in adult basic education classes in Sydney, Australia. The participants were 120 adults with lower education and literacy. An experimental computer-based manipulation compared 1) pictographs in 2 forms, shaded "blocks" and unshaded "dots"; and 2) bar charts across different orientations (horizontal/vertical) and numerator size (small <100, medium 100-499, large 500-999). Accuracy (size of error) and ease of processing (reaction time) were assessed on a gist task (estimating the larger chance of survival) and a verbatim task (estimating the size of difference). Preferences for different graph types were also assessed. Accuracy on the gist task was very high across all conditions (>95%) and not tested further. For the verbatim task, optimal graph type depended on the numerator size. For small numerators, pictographs resulted in fewer errors than bar charts (blocks: odds ratio [OR] = 0.047, 95% confidence interval [CI] = 0.023-0.098; dots: OR = 0.049, 95% CI = 0.024-0.099). For medium and large numerators, bar charts were more accurate (e.g., medium dots: OR = 4.29, 95% CI = 2.9-6.35). Pictographs were generally processed faster for small numerators (e.g., blocks: 14.9 seconds v. bars: 16.2 seconds) and bar charts for medium or large numerators (e.g., large blocks: 41.6 seconds v. 26.7 seconds). Vertical formats were processed slightly faster than horizontal graphs with no difference in accuracy. Most participants preferred bar charts (64%); however, there was no relationship with performance. For adults with low education and literacy, pictographs are likely to be the best format to use when displaying small numerators (<100/1000) and bar charts for larger numerators (>100/1000).

Discrete shear-transformation-zone plasticity modeling of notched bars

NASA Astrophysics Data System (ADS)

Kondori, Babak; Amine Benzerga, A.; Needleman, Alan

2018-02-01

Plane strain tension analyses of un-notched and notched bars are carried out using discrete shear transformation zone plasticity. In this framework, the carriers of plastic deformation are shear transformation zones (STZs) which are modeled as Eshelby inclusions. Superposition is used to represent a boundary value problem solution in terms of discretely modeled Eshelby inclusions, given analytically for an infinite elastic medium, and an image solution that enforces the prescribed boundary conditions. The image problem is a standard linear elastic boundary value problem that is solved by the finite element method. Potential STZ activation sites are randomly distributed in the bars and constitutive relations are specified for their evolution. Results are presented for un-notched bars, for bars with blunt notches and for bars with sharp notches. The computed stress-strain curves are serrated with the magnitude of the associated stress-drops depending on bar size, notch acuity and STZ evolution. Cooperative deformation bands (shear bands) emerge upon straining and, in some cases, high stress levels occur within the bands. Effects of specimen geometry and size on the stress-strain curves are explored. Depending on STZ kinetics, notch strengthening, notch insensitivity or notch weakening are obtained. The analyses provide a rationale for some conflicting findings regarding notch effects on the mechanical response of metallic glasses.

Heisenberg`s commutation relation for position x and momentum p, and its validity for relativistic harmonic oscillators are examined, using the techniques of Lie algebra and dual-bosonic representation of x, p and the Hamiltonian H. A modification with [x, p] =i{h_bar}({minus_plus} 1 + H/m{sub 0}c{sup 2}) is proposed for a particle and an antiparticle in a harmonic potential. For a 2 {times} 2 matrix representation for x, p and H operators, the quantized eigenenergy E is given by (E - m{sub 0}c{sup 2})/{h_bar}{omega} = 3/2, 5/2, 7/2, ..., where 1/2 is not allowed.
