    Study abroad programs have the potential to promote cultural, experiential, and personal development for escalating numbers of American college students each year. Despite reports that study abroad students may be at particular risk for increased and problematic alcohol use, there is limited empirical documentation of this risk. Thus, the present study used a longitudinal design to examine the factors associated with changes in alcohol use among college students studying in foreign countries. A sample of 177 students completed measures of demographics, drinking behavior, and perceived peer drinking behavior 1 month before departure and 1-month postreturn from study abroad trips. Analyses revealed that participants more than doubled their drinking during study abroad trips and those who drank at heavier levels while abroad returned home drinking at significantly elevated levels. This pattern of increased use while abroad was moderated by several factors, with participants studying abroad in Europe (e.g., Italy, France) and Oceania (e.g., Australia, New Zealand), those under the age of 21, those with higher intentions of drinking while abroad, and those with higher drinking perceptions of other study abroad students in their host country increased their alcohol consumption to a greater extent than other participants. Results suggest drinking while abroad is a concern warranting further investigation, especially regarding how changes in drinking may contribute to the experience of alcohol-related consequences abroad. Continued identification of the risk factors associated with increased drinking can help inform targeted predeparture preventive interventions with these students.

    The effect of water deprivation and water intake on experimental anxiety in rats was tested using burying behavior (BB) and social interaction (SI) anxiety paradigms. Two groups of animals were studied: a control group with free access to water, and a 72-h water-deprived experimental group. Anxiety was studied in a water-deprived group or following a 10-min period of ad lib water drinking. An increase in the mean time of defensive burying in animals deprived for 72 h was observed, whereas an important reduction occurred in the levels of burying behavior immediately after the animals were allowed to drink ad lib for 10 min. These results suggest that the observed increase in defensive burying in the water-deprived animals represents an anxiogenic effect, whereas the decrease in this behavior in water-satiated animals is considered an anxiolytic action. The temporal course of reduction in burying behavior, observed after water drinking, revealed that the anxiolytic action lasts 5 min, whereas 15-30 min after drinking, burying behavior levels were similar to those in the control group. In the social interaction experiment a partial anxiogenic/anxiolytic effect of water deprivation and water intake was observed. The adaptive meaning of anxiogenic and anxiolytic changes linked to consummatory behaviors in rats is discussed on the basis of behavioral and biochemical data.

    Full Text Available Abstract Background Raising prices through taxation on tobacco and alcohol products is a common strategy to raise revenues and reduce consumption. However, taxation policies are product specific, focusing either on alcohol or tobacco products. Several studies document interactions between the price of cigarettes and general alcohol use and it is important to know whether increased cigarette prices are associated with varying alcohol drinking patterns among different population groups. To inform policymaking, this study investigates the association of state cigarette prices with smoking, and current, binge, and heavy drinking by age group. Methods The 2001-2006 Behavioral Risk Factor Surveillance System surveys (n = 1,323,758 were pooled and analyzed using multiple regression equations to estimate changes in smoking and drinking pattern response to an increase in cigarette price, among adults aged 18 and older. For each outcome, a multiple linear probability model was estimated which incorporated terms interacting state cigarette price with age group. State and year fixed effects were included to control for potential unobserved state-level characteristics that might influence smoking and drinking. Results Increases in state cigarette prices were associated with increases in current drinking among persons aged 65 and older, and binge and heavy drinking among persons aged 21-29. Reductions in smoking were found among persons aged 30-64, drinking among those aged 18-20, and binge drinking among those aged 65 and older. Conclusions Increases in state cigarette prices may increase or decrease smoking and harmful drinking behaviors differentially by age. Adults aged 21-29 and 65 and older are more prone to increased drinking as a result of increased cigarette prices. Researchers, practitioners, advocates, and policymakers should work together to understand and prepare for these unintended consequences of tobacco taxation policy.

    Social norms are sustained and disseminated, both implicitly and explicitly, through the act of communication. As a result, communication researchers have sought to classify and target normative perceptions to enact social change. In line with this research, the current study investigated whether perceptions of past normative behavior, referred to here as historical norms, were significantly related to current behavior. Using the theory of normative behavior as a guiding framework, two studies were conducted to assess whether college student drinking behavior was related to one of two perceived historical drinking norms measures: historical consumption norms (i.e., the perceived percentage of students who drank over time) and historical tradition norms (i.e., the perception of drinking as a university tradition). Study 1 revealed that although historical consumption norms was not directly related to drinking behavior, it moderated the effect of descriptive norms on drinking behavior (p = .03). A full assessment of the theory of normative social behavior was conducted in study 2 to determine whether perceived historical drinking norms influenced behavior above and beyond both descriptive and injunctive norms. Findings demonstrated that historical tradition norms were significantly related to drinking behavior (p = .001), and marginally moderated the relationship between descriptive norms and drinking behavior (p = .09). These findings offer preliminary evidence in support of measuring perceived historical drinking norms in future campaigns and interventions designed to reduce drinking behavior.

  6. Learning about Drinking Water: How Important are the Three Dimensions of Knowledge that Can Change Individual Behavior?

    Full Text Available Clean drinking water, our most important resource, needs comprehensive protection. Due to its ubiquitous availability, the awareness of the importance of clean drinking water has partially vanished. Therefore, sensitizing within this context and improving individual ecological behavior has become an important issue in science curricula. We developed a student-centered guided-learning module based on nine workstations, with the themes: occurrence rates, purification methods, cleaning guidelines, distribution patterns, use and consumption, pollution, problems, types of drinking water and virtual water. One hundred and seventy four ninth to eleventh graders participated in our outreach intervention. All tasks presented via workstations were completed before participants inspected a nearby reed sewage treatment plant and completed hands-on experiments. For empirical analyses, we collected the newly acquired knowledge in three dimensions: system-knowledge, action-related knowledge and effectiveness knowledge, which together are assumed to provide a sufficient basis for conservation behavior. System knowledge directly affects action-related and effectiveness knowledge and these two types of knowledge, in turn, affect directly the ecological behavior. At all three test schedules, the three dimensions of knowledge correlated with each other, especially in both follow-up tests. The relevance of these results for schools is discussed.

    This study explored the association between alienating job conditions and problem drinking within the context of occupational status and workplace drinking subculture. From December 1994 to March 1995, a questionnaire survey was implemented in the manufactory sector in southern Taiwan. Within the questionnaire, any perceived self-estrangement, powerlessness and social isolation that the individual experienced in his work were measured as the alienating job conditions, and any negative physical, psychological and social consequences the individual experienced during the previous month were considered as affecting problem drinking. Of the 1117 subjects, 668 (61.8%) reported imbibing one or more drinks during the preceding month; the average daily alcohol consumption being 0.2+/-0.9 drinks. In addition, 188 (16.8%) subjects reported having experienced drinking-related problems in the preceding month. Workers with low occupational status were more likely to become problem drinkers when they felt comparatively self-estranged in their work. Further, those with a family history including any habitual drinker or those under more encouraging workplace drinking subculture were more likely to have drinking-related problems. For the prevention of problem-related drinking behavior, the workplace should be considered as the focus of our future intervention and management program.

    Full Text Available Co-morbid PTSD and alcohol use disorders are both common and debilitating. However, many of these studies rely on cross-sectional studies that obscure more complex relationships between PTSD and drinking. Event-level studies allow for examination of proximal relationships between PTSD and drinking. Among women (n=136 with past sexual victimization, n=40 no past trauma history, a two-part mixed hurdle model was used to examine daily PTSD and drinking. On days women experienced more intrusive and behavioral avoidance symptoms, they were more likely to drink. For a 2 SD increase in symptoms, there was a 5% increased likelihood of drinking, and for a 2 SD increase in dysphoric symptoms or negative affect, women drank approximately half drink less. Daily-level coping self-efficacy moderated the association between distress and drinking (IRR=0.91, p<0.01. Women who reported less coping drank more as their distress increased on a certain day whereas women who reported more coping drank about the same regardless of distress. Overall, findings suggest that specific PTSD symptoms are associated with higher alcohol use and that these relationships are moderated by daily coping self-efficacy. Implications of these findings for informing models of PTSD/AUD comorbidity, as well as clinical implications will be discussed.

    Although pharmacological blockade of both dopamine (DA) and opiate receptors has an inhibiting effect on appetitive motivated behaviors, it is still unclear which physiological mechanisms affected by these treatments underlie the behavioral deficit. To clarify this issue, we examined how pharmacological blockade of either DA (SCH23390+eticlopride at 0.2 mg/kg each) or opioid receptors (naloxone 1 mg/kg) affects motor activity and temperature fluctuations in the nucleus accumbens (NAcc), temporal muscle, and facial skin associated with motivated Coca-Cola drinking behavior in rats. In drug-free conditions, presentation of a cup containing 5 ml of Coca-Cola induced locomotor activation and rapid NAcc temperature increases, which both transiently decreased during drinking, and phasically increased again after the cup was emptied. Muscle temperatures followed this pattern, but increases were weaker and more delayed than those in the NAcc. Skin temperature rapidly dropped after cup presentation, remained at low levels during consumption, and slowly restored during post-consumption behavioral activation. By itself, DA receptor blockade induced robust decrease in spontaneous locomotion, moderate increases in brain and muscle temperatures, and a relative increase in skin temperatures, suggesting metabolic activation coupled with adynamia. Following this treatment (approximately 180 min), motor activation to cup presentation and Coca-Cola consumption were absent, but rats showed NAcc and muscle temperature increases following cup presentation comparable to control. Therefore, DA receptor blockade does not affect significantly central and peripheral autonomic responses to appetitive stimuli, but eliminates their behavior-activating effects, thus disrupting appetitive behavior and blocking consumption. Naloxone alone slightly decreased brain and muscle temperatures and increased skin temperatures, pointing at the enhanced heat loss and possible minor inhibition of basal

    Full Text Available Drinking games are a risk factor for behavioral and health problems among university students. Previous cross-sectional research by Hone, Carter, and McCullough (2013 replicated well-established sex differences in drinking game behaviors (i.e., that men are more active drinking game participants than are women and university drinking problems more generally. Hone et al. (2013 also found that these male-specific behavioral patterns are attributable in part to the fact that men's generally unrestricted sexual strategies, plus their social competitiveness, motivate them to participate in drinking games to display their fortitude and compete with same-sex rivals. Here, the authors conducted a study to evaluate with greater causal rigor whether sex differences in sexual restrictedness and social competitiveness—and sex differences in motivations for participating in drinking games in particular—are partially responsible for the sex differences in university students' drinking game behaviors and drinking problems. Sex differences in changes in frequency of drinking game participation were partially mediated by competitive motivations for participating in drinking games and by the effects of social competitiveness on competitive drinking game motivation. These findings lend additional support to the proposition that participation in drinking games is motivated in part by their suitability as a venue for sexual competition in university students' day-to-day lives.

    The purposes of this study are to estimate the stress level of university students, and to verify the relationships between stress level and drinking behavior. A questionnaire survey was administered to 430 university students in the Gangwon area in Korea from November 5 to November 28, 2008, and data from 391 students were used for the final statistical analysis. The most stressful factor was "Worry about academic achievements" (2.86 by Likert-type 4 point scale). The subjects were divided into two groups, a low stress group (≤ 65.0) and a high stress group (≥ 66.0), by the mean value (65.1) and median value (66.0) of the stress levels. The drinking frequency was not different between the two stress groups, but the amount of alcohol consumption was significantly different (P negatively correlated with drinking frequency and the amount of alcohol consumption (P negatively correlated with the amount of drinking (P effect of drinking was "Drinking enables me to get together with people and shape my sociability" (2.73). The higher stress group showed significantly higher scores on several items in the categories of motives (P negative experience (P effects (P alcohol consumption.

    Coca-Cola (Coke) and Pepsi are nearly identical in chemical composition, yet humans routinely display strong subjective preferences for one or the other. This simple observation raises the important question of how cultural messages combine with content to shape our perceptions; even to the point of modifying behavioral preferences for a primary reward like a sugared drink. We delivered Coke and Pepsi to human subjects in behavioral taste tests and also in passive experiments carried out during functional magnetic resonance imaging (fMRI). Two conditions were examined: (1) anonymous delivery of Coke and Pepsi and (2) brand-cued delivery of Coke and Pepsi. For the anonymous task, we report a consistent neural response in the ventromedial prefrontal cortex that correlated with subjects' behavioral preferences for these beverages. In the brand-cued experiment, brand knowledge for one of the drinks had a dramatic influence on expressed behavioral preferences and on the measured brain responses.

  19. Motivation to change drinking behavior: the differences between alcohol users from an outpatient gastroenterology clinic and a specialist alcohol treatment service

    Full Text Available CONTEXT AND OBJECTIVE: For some patients who have developed significant alcohol-related physical disease, total abstinence from alcohol may offer the best chance of survival. The aim of this study was to investigate motivation for treatment in two groups of alcohol users: outpatients from the gastroenterology clinic and outpatients from the specialist alcohol treatment service. DESIGN AND SETTING: Cross-sectional study, at a federally funded public teaching hospital. METHODS: The sample studied was 151 outpatients from the gastroenterology clinic and 175 from the specialist alcohol treatment service. The interview was conducted in the outpatient clinics at the first appointment, and consisted of demographic questions and scales for measuring quality of life, alcohol dependence, pattern of alcohol, motivation for treatment and consequences of alcohol consumption. RESULTS: The results suggested that outpatients from the gastroenterology clinic were less dependent on alcohol, had suffered fewer consequences from alcohol and had fewer emotional and mental health problems than did the outpatients from the alcohol treatment service. In relation to their stages of change, the gastroenterology outpatients presented high precontemplation scores at the beginning of treatment while outpatients of alcohol treatment service showed higher scores in contemplation, action and maintenance. CONCLUSION: The medical treatment may be a reason for the temporary alcohol abstinence behavior among the gastroenterology outpatients.

  20. Adolescent binge drinking leads to changes in alcohol drinking, anxiety, and amygdalar corticotropin releasing factor cells in adulthood in male rats.

    Full Text Available Heavy episodic drinking early in adolescence is associated with increased risk of addiction and other stress-related disorders later in life. This suggests that adolescent alcohol abuse is an early marker of innate vulnerability and/or binge exposure impacts the developing brain to increase vulnerability to these disorders in adulthood. Animal models are ideal for clarifying the relationship between adolescent and adult alcohol abuse, but we show that methods of involuntary alcohol exposure are not effective. We describe an operant model that uses multiple bouts of intermittent access to sweetened alcohol to elicit voluntary binge alcohol drinking early in adolescence (~postnatal days 28-42 in genetically heterogeneous male Wistar rats. We next examined the effects of adolescent binge drinking on alcohol drinking and anxiety-like behavior in dependent and non-dependent adult rats, and counted corticotropin-releasing factor (CRF cell in the lateral portion of the central amygdala (CeA, a region that contributes to regulation of anxiety- and alcohol-related behaviors. Adolescent binge drinking did not alter alcohol drinking under baseline drinking conditions in adulthood. However, alcohol-dependent and non-dependent adult rats with a history of adolescent alcohol binge drinking did exhibit increased alcohol drinking when access to alcohol was intermittent. Adult rats that binged alcohol during adolescence exhibited increased exploration on the open arms of the elevated plus maze (possibly indicating either decreased anxiety or increased impulsivity, an effect that was reversed by a history of alcohol dependence during adulthood. Finally, CRF cell counts were reduced in the lateral CeA of rats with adolescent alcohol binge history, suggesting semi-permanent changes in the limbic stress peptide system with this treatment. These data suggest that voluntary binge drinking during early adolescence produces long-lasting neural and behavioral effects

    College students binge drink more frequently than the broader population, yet most individuals "mature out" of binge drinking. Impulsivity and sensation seeking traits are important for understanding who is at risk for maintaining binge drinking across college and the transition to adult roles. We use latent class growth analysis (LCGA) to examine longitudinal binge-drinking trajectories spanning from the end of high school through 2 years after college (M ages = 18.4 to 23.8). Data were gathered over 10 waves from students at a large Southwestern university (N = 2,245). We use latent factor models to estimate changes in self-reported impulsive (IMP) and sensation-seeking (SS) personality traits across 2 time periods-(a) the end of high school to the end of college and (b) the 2-year transition out of college. LCGA suggested 7 binge-drinking trajectories: frequent, moderate, increasing, occasional, low increasing, decreasing, and rare. Models of personality showed that from high school through college, change in SS and IMP generally paralleled drinking trajectories, with increasing and decreasing individuals showing corresponding changes in SS. Across the transition out of college, only the increasing group demonstrated a developmentally deviant increase in IMP, whereas all other groups showed normative stability or decreases in both IMP and SS. These data indicate that "late bloomers," who begin binge drinking only in the later years of college, are a unique at-risk group for drinking associated with abnormal patterns of personality maturation during emerging adulthood. Our results indicate that personality targeted interventions may benefit college students.

    Full Text Available Abstract Background Alcohol drinking is frequently related to behavioral problems, which lead to a number of negative consequences. This study was to evaluate the characteristics of male high school students who drink, the drinking patterns among them, and the associations between current drinking and other health risk behaviors which focused on personal safety, violence-related behaviors, suicide and sexual behaviors. Method A cross-sectional study was conducted to explore current alcohol drinking and health-risk behaviors among male high school students in central Thailand. Five thousand one hundred and eighty four male students were classified into 2 groups according to drinking in the previous 30 days (yes = 631, no = 4,553. Data were collected by self-administered, anonymous questionnaire which consisted of 3 parts: socio-demographic factors, health-risk behaviors and alcohol drinking behavior during the past year from December 2007 to February 2008. Results The results showed that the percent of current drinking was 12.17. Most of them were 15-17 years (50.21%. Socio-demographic factors such as age, educational level, residence, cohabitants, grade point average (GPA, having a part time job and having family members with alcohol/drug problems were significantly associated with alcohol drinking (p Conclusions An increased risk of health-risk behaviors, including driving vehicles after drinking, violence-related behaviors, sad feelings and attempted suicide, and sexual behaviors was higher among drinking students that led to significant health problems. Effective intervention strategies (such as a campaign mentioning the adverse health effects and social consequences to the risk groups, and encouraging parental and community efforts to prevent drinking among adolescents should be implemented to prevent underage drinking and adverse consequences.

    Problem drinking during the college years continues to be an important area of study. Subjective evaluations of consequences have recently been demonstrated to predict future drinking behavior; however, what predicts those evaluations is yet unknown. Social Learning Theory (SLT) provides a guiding framework in this study. Primary aims are to investigate whether individual differences in past experience with alcohol consequences and normative perceptions of alcohol consequences predict subjective evaluations (i.e., the extent to which consequences are perceived as negative, aversive, or severe) and weekly drinking behavior. We also test whether evaluations mediate the influence of past consequences and norms on weekly drinking behavior. Following a baseline assessment, participants (N = 96 regularly drinking college students, 52% female) completed ten weekly web-based surveys on previous week alcohol use, consequences, and subjective evaluations of those consequences. A series of hierarchical linear models were used to test hypotheses. Most mediational pathways were not supported - weekly level evaluations do not appear to fully explain the effect of norms or past experience on weekly level drinking behavior. However, results demonstrated that normative perceptions of and past experience with consequences were associated with both weekly drinking behavior and subjective evaluations, and evaluations remained significant predictors of alcohol use behavior after accounting for these important between-person influences. Findings support the importance placed by SLT on cognition in drinking behavior, and suggest that norms for consequences and subjective evaluations may be appropriate targets of intervention in college students.

    Full Text Available Abstract Background Visual analog scales (VAS are sometimes used to assess change constructs that are often considered critical for change. Aims of Study: 1. To determine the association of readiness to change, importance of changing and confidence in ability to change alcohol and tobacco use at baseline with the risk for drinking (more than 21 drinks per week/6 drinks or more on a single occasion more than once per month and smoking (one or more cigarettes per day six months later. 2. To determine the association of readiness, importance and confidence with alcohol (number of drinks/week, number of binge drinking episodes/month and tobacco (number of cigarettes/day use at six months. Methods This is a secondary analysis of data from a multi-substance brief intervention randomized trial. A sample of 461 Swiss young men was analyzed as a prospective cohort. Participants were assessed at baseline and six months later on alcohol and tobacco use, and at baseline on readiness to change, importance of changing and confidence in ability to change constructs, using visual analog scales ranging from 1–10 for drinking and smoking behaviors. Regression models controlling for receipt of brief intervention were employed for each change construct.

    Full Text Available Behavior that has changed following promotion campaigns is usually not maintained at its initial level. Psychosocial factors for initiating behavior are often not the same as for the continuation of health behaviors such as water treatment and are much less understood. Better knowledge of factors for behavioral continuation would help to improve programs, both in the design of strategies for sustainable behavior change and by defining stronger criteria for the evaluation of sustainability. This study compared the mindsets of caregivers who continuously performed household drinking water treatment over time with individuals that stopped doing so in a population sample from Chad. Several factors from health psychology based on the Risks, Attitudes, Norms, Abilities, and Self-Regulation (RANAS model were used to compare the two groups and examine their differing development. Normative factors such as others’ behavior, personal obligation, social support and discourse, perceived self-efficacy convictions, action control, and intention best discriminated between the two groups and developed significantly more positively over time for continuers of water treatment. These factors should be considered when designing future interventions intended to lead to sustainable behavior change.

    Attempts at removal of drinking water biofilms rely on various preventive and curative strategies such as nutrient reduction in drinking water, disinfection or water flushing, which have demonstrated limited efficiency. The main reason for these failures is the cohesiveness of the biofilm driven by the physico-chemical properties of its exopolymeric matrix (EPS). Effective cleaning procedures should break up the matrix and/or change the elastic properties of bacterial biofilms. The aim of this study was to evaluate the change in the cohesive strength of two-month-old drinking water biofilms under increasing hydrodynamic shear stress τw (from ∼0.2 to ∼10 Pa) and shock chlorination (applied concentration at T0: 10 mg Cl2/L; 60 min contact time). Biofilm erosion (cell loss per unit surface area) and cohesiveness (changes in the detachment shear stress and cluster volumes measured by atomic force microscopy (AFM)) were studied. When rapidly increasing the hydrodynamic constraint, biofilm removal was found to be dependent on a dual process of erosion and coalescence of the biofilm clusters. Indeed, 56% of the biofilm cells were removed with, concomitantly, a decrease in the number of the 50-300 μm(3) clusters and an increase in the number of the smaller (i.e., 600 μm(3)) ones. Moreover, AFM evidenced the strengthening of the biofilm structure along with the doubling of the number of contact points, NC, per cluster volume unit following the hydrodynamic disturbance. This suggests that the compactness of the biofilm exopolymers increases with hydrodynamic stress. Shock chlorination removed cells (-75%) from the biofilm while reducing the volume of biofilm clusters. Oxidation stress resulted in a decrease in the cohesive strength profile of the remaining drinking water biofilms linked to a reduction in the number of contact points within the biofilm network structure in particular for the largest biofilm cluster volumes (>200 μm(3)). Changes in the cohesive

    Full Text Available Abstract Background Heavy alcohol use among U.S. college students is a major contributor to young adult morbidity and mortality. The aim of this study was to examine whether college alcohol policy enforcement levels predict changes in student drinking and related behaviors in a state system of public colleges and universities, following a system-wide change to a stricter policy. Methods Students and administrators at 11 Massachusetts public colleges/universities completed surveys in 1999 (N of students = 1252, one year after the policy change, and again in 2001 (N = 1074. We calculated policy enforcement scores for each school based on the reports of deans of students, campus security chiefs, and students, and examined the correlations between perceived enforcement levels and the change in student drinking rates over the subsequent two year period, after weighting the 2001 data to adjust for demographic changes in the student body. Results Overall rates of any past-30-days drinking, heavy episodic drinking, and usual heavy drinking among past-30-days drinkers were all lower in 2001 compared to 1999. School-level analyses (N = 11 found deans' baseline reports of stricter enforcement were strongly correlated with subsequent declines in heavy episodic drinking (Pearson's r = -0.73, p = 0.011. Moreover, consistently high enforcement levels across time, as reported by deans, were associated with greater declines in heavy episodic drinking. Such relationships were not found for students' and security chiefs' reports of enforcement. Marijuana use did not rise during this period of decline in heavy drinking. Conclusions Study findings suggest that stronger enforcement of a stricter alcohol policy may be associated with reductions in student heavy drinking rates over time. An aggressive enforcement stance by deans may be an important element of an effective college alcohol policy.

    Adolescent peer groups with pro-drinking group norms are a well-established source of influence for alcohol initiation and use. However, classic experimental studies of social influence, namely 'minority influence', clearly indicate social situations in which an individual can resist conforming to the group norm. Using the National Longitudinal Study of Adolescent Health ("Add Health"), a nationally representative sample of adolescents, we find evidence that being a non-drinking adolescent does not unilaterally put youth at risk for drinking onset when faced with a friendship network where the majority of friends drink. Our results also show that a non-drinking adolescent with a majority of drinking friends is significantly less likely to initiate alcohol abuse if he or she has a minority of non-drinking friend(s). Furthermore, a drinking adolescent with a majority of friends who drink has a decreased probability of continuing to drink and has overall lower levels of consumption if he or she has a minority of friends who do not drink. Our findings recognize that adolescent in-group friendships are a mix of behavioral profiles and can perhaps help adolescents continue or begin to abstain alcohol use even when in a friendship group supportive of alcohol use.

    Ultimately, effective climate change communication results in a change in behavior, whether the change is individual, household or collective actions within communities. We describe two efforts to promote climate-friendly behavior via climate communication and behavior change theory. Importantly these efforts are designed to scale climate communication principles focused on behavior change rather than soley emphasizing climate knowledge or attitudes. Both cases are embedded in rigorous evaluations (randomized controlled trial and quasi-experimental) of primary and secondary outcomes as well as supplementary analyses that have implications for program refinement and program scaling. In the first case, the Girl Scouts "Girls Learning Environment and Energy" (GLEE) trial is scaling the program via a Massive Open Online Course (MOOC) for Troop Leaders to teach the effective home electricity and food and transportation energy reduction programs. The second case, the Alliance for Climate Education (ACE) Assembly Program, is advancing the already-scaled assembly program by using communication principles to further engage youth and their families and communities (school and local communities) in individual and collective actions. Scaling of each program uses online learning platforms, social media and "behavior practice" videos, mastery practice exercises, virtual feedback and virtual social engagement to advance climate-friendly behavior change. All of these communication practices aim to simulate and advance in-person train-the-trainers technologies.As part of this presentation we outline scaling principles derived from these two climate change communication and behavior change programs.

The aim of this study was to analyze the factors influencing changes in concentrations of iron (Fe and manganese (Mn in Kaunas drinking water distribution network. Analytical study on the drinking water quality was performed. Concentrations of manganese and iron in drinking water were assessed by using an atomic absorption spectrophotometer. Correlation between the changes in manganese concentrations and the distance from the water treatment plant was found, the correlation coefficient was -0.367; p=0.022, however, for iron it was 0.179; p = 0.148. At some sampling points the concentrations of Mn and Fe exceeded the regulated limits. To ensure the water quality and to avoid possible adverse health effects it is recommended to install Mn and Fe filter system in a consumer's drinking water pipeline.

    Monitoring and control of water treatment plants play an essential role in ensuring high quality drinking water and avoiding health-related problems or economic losses. The most common quality variables, which can be used also for assessing the efficiency of the water treatment process, are turbidity and residual levels of coagulation and disinfection chemicals. In the present study, the trend indices are developed from scaled measurements to detect warning signs of changes in the quality variables of drinking water and some operating condition variables that strongly affect water quality. The scaling is based on monotonically increasing nonlinear functions, which are generated with generalized norms and moments. Triangular episodes are classified with the trend index and its derivative. Deviation indices are used to assess the severity of situations. The study shows the potential of the described trend analysis as a predictive monitoring tool, as it provides an advantage over the traditional manual inspection of variables by detecting changes in water quality and giving early warnings.

    The objective of this study is to describe energy drink consumption and health behaviors among college students attending a predominantly minority university. Undergraduate and graduate students attending a private, minority-serving university were invited to participate in an online survey between September 2009 and August 2010. Out of 2,500 students, 407 participated yielding a response of 16 %. Analysis assessed energy drink consumption as well as participation in sport activities and high-risk behaviors. Energy drink consumption is significantly related with drinking alcohol to inebriation and driving (r = .14, p alcohol to inebriation and driving F (1, 186) = 6.12, p consumption is a common practice among racial minority university students. Tailored health promotion strategies and interventions are needed to address misconceptions of energy drink and alcohol mixing.

    2012-06-01

    Strategies that are most effective in both prevention and management of chronic disease consider factors such as age, ethnicity, community, and technology. Most behavioral change strategies derive their components from application of the health belief model, the theory of reasoned action/theory of planned behavior, transtheoretical model, and social cognitive theory. Many tools such as the readiness ruler and personalized action plan form are available to assist health care teams to facilitate healthy behavior change. Primary care providers can support behavior changes by providing venues for peer interventions and family meetings and by making new partnerships with community organizations.

    To decrease the prevalence and the amount of alcohol consumption among students, health messages advocating responsible alcohol behavior can be used. However, it is unclear whether responsible drinking messages are most effective when they use a gain frame, presenting the advantages of responsible drinking, or a loss frame, presenting the disadvantages of irresponsible drinking. This study tests the effects of framing and the moderating role of involvement with the issue of responsible drinking. A three-wave, between-subjects, experimental study was conducted, in which participants (N = 90) were exposed to either a gain- or loss-framed message about responsible drinking behavior at Wave 2. At all three waves, attitudes, intentions and behavior toward responsible drinking were measured. Results showed that for participants with low issue- involvement, a gain frame led to more positive attitudes and intentions toward responsible alcohol use, whereas a loss frame did not have any effects for them. For participants with high issue involvement, a loss frame led to more positive attitudes and intentions toward responsible alcohol use, whereas a gain frame did not have an effect on attitude and only a delayed effect on intention. However, there were no effects of frame and issue involvement on adhering to the guideline of responsible alcohol use and average drinking behavior.

    The α-Ca(2+)/calmodulin-dependent protein kinase II (αCaMKII) is a crucial enzyme controlling plasticity in the brain. The autophosphorylation of αCaMKII works as a 'molecular memory' for a transient calcium activation, thereby accelerating learning. We investigated the role of αCaMKII autophosphorylation in the establishment of alcohol drinking as an addiction-related behavior in mice. We found that alcohol drinking was initially diminished in αCaMKII autophosphorylation-deficient αCaMKII(T286A) mice, but could be established at wild-type level after repeated withdrawals. The locomotor activating effects of a low-dose alcohol (2 g/kg) were absent in αCaMKII(T286A) mice, whereas the sedating effects of high-dose (3.5 g/kg) were preserved after acute and subchronic administration. The in vivo microdialysis revealed that αCaMKII(T286A) mice showed no dopamine (DA) response in the nucleus accumbens to acute or subchronic alcohol administration, but enhanced serotonin (5-HT) responses in the prefrontal cortex. The attenuated DA response in αCaMKII(T286A) mice was in line with altered c-Fos activation in the ventral tegmental area after acute and subchronic alcohol administration. In order to compare findings in mice with the human condition, we tested 23 single-nucleotide polymorphisms (SNPs) in the CAMK2A gene for their association with alcohol dependence in a population of 1333 male patients with severe alcohol dependence and 939 controls. We found seven significant associations between CAMK2A SNPs and alcohol dependence, one of which in an autophosphorylation-related area of the gene. Together, our data suggest αCaMKII autophosphorylation as a facilitating mechanism in the establishment of alcohol drinking behavior with changing the DA-5-HT balance as a putative mechanism.

    Research suggests that workplace harassment (WH) significantly predicts alcohol use and problem drinking behavior, but has generally failed to consider concurrent effects of other sources of stress. This two-wave study (n=1418) is the first to explore whether sexual harassment (SH) and generalized workplace harassment (GWH) predict increased drinking independently of the effects of job and life stress, and whether effects differ by gender, in a nationally representative sample. SH and GWH predicted increases in problem drinking one year later for men but not women, while life stress was associated with increased problem drinking for women but not men. This study confirms the importance of examining the associations between different types of stressors and drinking-related outcomes in gendered contexts. PMID:18384975

    The present study examined associations between use of protective behavioral strategies (PBS) by college students and their friends and drinking-related outcomes during Spring Break (SB). Moreover, this study examined the influence of friends' own PBS use on participants' PBS use during SB. Participants included college students (N = 694) and their nominated friends (N = 131) who were part of a larger study of SB drinking. Data were collected via web-based surveys that participants and friends took after SB, which assessed SB PBS, drinking, and related negative consequences. Results indicated that higher levels of Serious Harm Reduction (SHR) strategies and Limiting/Stopping (LS) strategies were associated with increased consumption, higher likelihood of experiencing any consequences, and an increased number of consequences. A different pattern emerged for Manner of Drinking (MD) strategy use; participants utilizing higher levels of MD strategies drank less and had fewer consequences. LS and MD strategies used by the participant's friends appeared to have less of an impact on the participant's drinking outcomes. However, greater friends' use of SHR strategies was associated with increased alcohol use by the participant, but not with consequences. Greater friends' use of SHR strategies was associated with greater SHR strategy use by the participant. Friends' LS and MD strategies were not associated with participant drinking, consequences, or PBS. These findings highlight the potential utility of interventions that focus on drinking behaviors on specific high-risk occasions for those at risk as well as for their friends.

    This study examined the relative importance of climate change and drinking-water treatment for gastrointestinal illness incidence in children (age climate change and drinking-water treatment installation may alter gastrointestinal illness incidence. Future precipitation values were modeled by 13 global climate models and three greenhouse-gas emissions levels. The second analysis was rerun using three pathways: (1) only climate change, (2) climate change and the same slow pace of treatment installation observed over 1991-2010, and (3) climate change and the rapid rate of installation observed over 2011-2016. The results illustrate the risks that climate change presents to small rural groundwater municipalities without drinking water treatment. Climate-change-related seasonal precipitation changes will marginally increase the gastrointestinal illness incidence rate (mean: ˜1.5%, range: -3.6-4.3%). A slow pace of treatment installation somewhat decreased precipitation-associated gastrointestinal illness incidence (mean: ˜3.0%, range: 0.2-7.8%) in spite of climate change. The rapid treatment installation rate largely decreases the gastrointestinal illness incidence (mean: ˜82.0%, range: 82.0-83.0%).

  12. Dissemination of drinking water contamination data to consumers: a systematic review of impact on consumer behaviors.

    Directory of Open Access Journals (Sweden)

    Patricia J Lucas

    Full Text Available BACKGROUND: Drinking water contaminated by chemicals or pathogens is a major public health threat in the developing world. Responses to this threat often require water consumers (households or communities to improve their own management or treatment of water. One approach hypothesized to increase such positive behaviors is increasing knowledge of the risks of unsafe water through the dissemination of water contamination data. This paper reviews the evidence for this approach in changing behavior and subsequent health outcomes. METHODS/PRINCIPAL FINDINGS: A systematic review was conducted for studies where results of tests for contaminants in drinking water were disseminated to populations whose water supply posed a known health risk. Studies of any design were included where data were available from a contemporaneous comparison or control group. Using multiple sources >14,000 documents were located. Six studies met inclusion criteria (four of arsenic contamination and two of microbiological contamination. Meta-analysis was not possible in most cases due to heterogeneity of outcomes and study designs. Outcomes included water quality, change of water source, treatment of water, knowledge of contamination, and urinary arsenic. Source switching was most frequently reported: of 5 reporting studies 4 report significantly higher rates of switching (26-72% among those who received a positive test result and a pooled risk difference was calculate for 2 studies (RD = 0.43 [CI0.4.0-0.46] 6-12 months post intervention suggesting 43% more of those with unsafe wells switched source compared to those with safe wells. Strength of evidence is low since the comparison is between non-equivalent groups. Two studies concerning fecal contamination reported non-significant increases in point-of-use water treatment. CONCLUSION: Despite the publication of some large cohort studies and some encouraging results the evidence base to support dissemination of

  13. Exploring Perceptions and Behaviors about Drinking Water in Australia and New Zealand: Is It Risky to Drink Water, When and Why?

    Directory of Open Access Journals (Sweden)

    2016-02-01

    Full Text Available Consumers in most developed countries, including Australia and New Zealand, presume their drinking water is safe. How social perceptions about drinking water are formed, however, remains inadequately explored in the research literature. This research contributes exploratory insights by examining factors that affect consumer perceptions and behaviors. Individual perceptions of drinking water quality and actions undertaken to mitigate perceived risks were collected during 183 face-to-face interviews conducted at six research sites. Qualitative thematic analysis revealed the majority did not consider drinking water a “risky” activity, trusted water management authorities to manage all safety issues and believed self-evaluation of drinking water’s taste and appearance were sufficient measures to ensure safe consumption. Quantitatively, significant relationships emerged between water quality perceptions and sex, employment status, drinking water treatment and trust in government to provide safe water. Expert advice was rarely sought, even by those who believed drinking tap water posed some health risks. Generational differences emerged in media usage for drinking water advice. Finally, precautionary measures taken at home and abroad often failed to meet national drinking water guidelines. Three major conclusions are drawn: a. broad lack of awareness exists about the most suitable and safe water treatment activities, as well as risks posed; b. health literacy and interest may be improved through greater consumer involvement in watershed management; and c. development of health campaigns that clearly communicate drinking water safety messages in a timely, relevant and easily understandable fashion may help mitigate actual risks and dispel myths.

    Para-social behavior is a form of quasi-interpersonal behavior that results when audience members develop bonds with media personalities that can resemble interpersonal social interaction, but is not usually applied to political communication. This study tested whether the "Drinking-Buddy" Scale, a simple question frequently used in political communication, could be interpreted as a single-item measure of para-social behavior with respect to political candidates in terms of image judgments related to interpersonal attraction and perceived similarity to self. The participants were college students who had voted in the 2008 election. They rated the candidates, Obama or McCain, as drinking buddies and then rated the candidates' perceived similarity to themselves in attitude and background, and also the social and task attraction to the candidate. If the drinking-buddy rating serves as a proxy measure for para-social behavior, then it was expected that participants' ratings for all four kinds of similarity to and attraction toward a candidate would be higher for the candidate they chose as a drinking buddy. The directional hypotheses were supported for interpersonal attraction, but not for perceived similarity. These results indicate that the drinking-buddy scale predicts ratings of interpersonal attraction, while voters may view perceived similarity as an important but not essential factor in their candidate preference.

    Brain nicotinic acetylcholine receptors (nAChRs) have been implicated in the rewarding effects of ethanol and other drugs of abuse. The present study examined the effects of two important nicotinic ligands that target nAChRs, on ethanol consumption in drinking-in-the-dark or continuous access two-bottle choice drinking procedures in C57BL/6J mice. Nicotinic alkaloids such as lobeline or cytisine were administered via subcutaneous (s.c.) injections about 25 min before offering ethanol solutions. Pretreatment with lobeline (4 or 10mg/kg, s.c.) or cytisine (1.5 or 3mg/kg, s.c.) significantly reduced ethanol drinking-in-the-dark (g/kg) post 2-h and 4-h treatment, relative to control. In continuous access drinking procedure, pretreatment with lobeline (4 or 10mg/kg, s.c.) significantly reduced ethanol consumption post 1-h, 2-h, 4-h and 12-h treatment and pretreatment with cytisine (0.5, 1.5 or 3mg/kg, s.c.) significantly reduced ethanol consumption across 4-h post treatment, relative to control. Neither lobeline nor cytisine significantly affected water or sucrose solution (10% w/v) intake during drinking-in-the-dark or continuous drinking procedures, relative to control. These findings provide evidence that nAChR-mediated signaling plays a critical role in ethanol drinking behavior in mice and nicotinic ligands have therapeutic potential for cessation of binge-like ethanol drinking and dependence in humans.

  19. Mosquitoes drink with a burst in reserve: explaining pumping behavior with a fluid mechanics model

    2014-11-01

    Mosquitoes drink using a pair of in-line pumps in the head that draw liquid food through the proboscis. Experimental observations with synchrotron x-ray imaging indicate two modes of drinking: a predominantly occurring continuous mode, in which the cibarial and pharyngeal pumps expand cyclically at a constant phase difference, and an occasional, isolated burst mode, in which the pharyngeal pump expansion is 10 to 30 times larger than in the continuous mode. We have used a reduced order model of the fluid mechanics to hypothesize an explanation of this variation in drinking behavior. Our model results show that the continuous mode is more energetically efficient, whereas the burst mode creates a large pressure drop across the proboscis, which could potentially be used to clear blockages. Comparisons with pump knock-out configurations demonstrate different functional roles of the pumps in mosquito feeding. This material is based upon work supported by the NSF under Grant No. #0938047.

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

    The water intake of 41 lactating dairy cows managed according to current dairy farm practices was individually and continuously monitored to 1) investigate drinking behavior and 2) determine factors affecting water intake. The cows were housed in a free-stall barn and fed once daily with a corn silage and concentrate-based total mixed ration (48% dry matter content; 20.6 +/- 3.3 kg/d of dry matter intake). Cows were milked twice daily, with a yield of 26.5 +/- 5.9 kg/d. The daily free water intake (FWI) was 83.6 +/- 17.1 L, achieved during 7.3 +/- 2.8 drinking bouts. The drinking bout water intake was 12.9 +/- 5.0 L. Almost three-fourths of the FWI occurred during working hours (0600 to 1900 h). Consumption peaks corresponded to feeding and milking times. More than one quarter of the daily FWI was met during the 2 h after each milking. About 75% of the present cows visited the watering point at least once during the 2 h after the evening milking. It is probable that drinking behavior evolved with lactation, but further studies are required to identify the relationship between lactation stage and drinking behavior. The most relevant factors affecting the daily FWI of lactating cows were best combined according to the following predictive equation: (R(2) = 0.45; n = 41 cows, n = 1,837): FWI, L/d = 1.53 x dry matter intake (kg/d) + 1.33 x milk yield (kg/d) + 0.89 x dry matter content (%) + 0.57 x minimum temperature ( degrees C) - 0.30 x rainfall (mm/d) - 25.65. The results obtained using these equations were in agreement with the equations developed by other researchers.

    Full Text Available Abstract Background The consumption of liquid calories has been implicated in the development of obesity and weight gain. Energy-containing drinks are often reported to have a weak satiety value: one explanation for this is that because of their fluid texture they are not expected to have much nutritional value. It is important to consider what features of these drinks can be manipulated to enhance their expected satiety value. Two studies investigated the perception of subtle changes in a drink’s viscosity, and the extent to which thick texture and creamy flavour contribute to the generation of satiety expectations. Participants in the first study rated the sensory characteristics of 16 fruit yogurt drinks of increasing viscosity. In study two, a new set of participants evaluated eight versions of the fruit yogurt drink, which varied in thick texture, creamy flavour and energy content, for sensory and hedonic characteristics and satiety expectations. Results In study one, participants were able to perceive small changes in drink viscosity that were strongly related to the actual viscosity of the drinks. In study two, the thick versions of the drink were expected to be more filling and have a greater expected satiety value, independent of the drink’s actual energy content. A creamy flavour enhanced the extent to which the drink was expected to be filling, but did not affect its expected satiety. Conclusions These results indicate that subtle manipulations of texture and creamy flavour can increase expectations that a fruit yogurt drink will be filling and suppress hunger, irrespective of the drink’s energy content. A thicker texture enhanced expectations of satiety to a greater extent than a creamier flavour, and may be one way to improve the anticipated satiating value of energy-containing beverages.

    Friendship tie choices in adolescent social networks coevolve simultaneously with youths' cigarette smoking and drinking. We estimate direct and multiplicative relationships between both peer influence and peer selection with salient parental factors affecting both friendship tie choice and the use of these 2 substances. We utilize 1 sample of 12 small schools and a single large school extracted from the National Longitudinal Study of Adolescent to Adult Health. Using a Stochastic Actor-Based modeling approach over 3 waves, we find: (a) a peer selection effect, as adolescents nominated others as friends based on cigarette and alcohol use levels across samples; (b) a peer influence effect, as adolescents adapted their smoking and drinking behaviors to those of their best friends across samples; (c) reciprocal effect between cigarette and alcohol usage in the small school sample; (d) a direct effect of parental support and the home smoking environment on adolescent friendship tie choice in the small school sample; (e) a direct effect of the home smoking environment on smoking across samples; (f) a direct effect of the home drinking environment on alcohol use across samples; and (g) a direct effect of parental monitoring on alcohol use across samples. We observed an interaction between parental support and peer influence in affecting drinking, and an interaction between the home drinking environment and peer influence on drinking, in the small school sample. Our findings suggested the importance of delineating direct and synergistic pathways linking network processes and parental influence as they affect concurrent cigarette and alcohol use.

    Maternal risk drinking may be a risk factor for child behavior problems even if the mother has discontinued this behavior. Whether pre-pregnancy risk drinking is an independent predictor of child behavior problems, or whether a potential effect may be explained by maternal alcohol use during and after pregnancy or other adverse maternal characteristics, is not known. Employing data from the Norwegian Mother and Child Cohort Study (MoBa), longitudinal associations between maternal pre-pregnancy risk drinking and behavior problems in toddlers aged 18 and 36 months were examined. Included in the study was mothers answering MoBa questionnaires when the child was 18 (N = 56,682) and 36 months (N = 46,756), and who had responded to questions regarding pre-pregnancy risk drinking at gestation week 17/18, using the screening instrument T-ACE. Toddler behavior problems were measured with items from Child Behavior Checklist. Associations were analyzed with multivariate logistic regression, controlling for pre and postnatal alcohol use, as well as other relevant covariates. Pre-pregnancy risk drinking was associated with child behavior problems at 18 and 36 months, even after controlling for pre and postnatal alcohol use. Maternal ADHD and anxiety and depression were the only covariates that had any substantial impact on the associations. When all covariates were included in the model, the associations were weak for internalizing behavior problems and non-significant for externalizing behavior problems. Pre-pregnancy risk drinking may predict early development of behavior problems in the offspring. This increased risk may be due to other adverse maternal characteristics associated with risk drinking, in particular co-occurring maternal psychopathology.

  8. Evaluation of effectiveness of class-based nutrition intervention on changes in soft drink and milk consumption among young adults

    Full Text Available Abstract Background During last few decades, soft drink consumption has steadily increased while milk intake has decreased. Excess consumption of soft drinks and low milk intake may pose risks of several diseases such as dental caries, obesity, and osteoporosis. Although beverage consumption habits form during young adulthood, which has a strong impact on beverage choices in later life, nutrition education programs on beverages are scarce in this population. The purpose of this investigation was 1 to assess soft drink and milk consumption and 2 to evaluate the effectiveness of 15-week class-based nutrition intervention in changing beverage choices among college students. Methods A total of 80 college students aged 18 to 24 years who were enrolled in basic nutrition class participated in the study. Three-day dietary records were collected, verified, and analyzed before and after the intervention. Class lectures focused on healthful dietary choices related to prevention of chronic diseases and were combined with interactive hands on activities and dietary feedback. Results Class-based nutrition intervention combining traditional lecture and interactive activities was successful in decreasing soft drink consumption. Total milk consumption, specifically fat free milk, increased in females and male students changed milk choice favoring skim milk over low fat milk. (1% and 2%. Conclusion Class-based nutrition education focusing on prevention of chronic diseases can be an effective strategy in improving both male and female college students' beverage choices. Using this type of intervention in a general nutrition course may be an effective approach to motivate changes in eating behaviors in a college setting.

    Among the most widely predicted and accepted consequences of global climate change are increases in both the frequency and severity of a variety of extreme weather events. Such weather events include heavy rainfall and floods, cyclones, droughts, heatwaves, extreme cold, and wildfires, each of which can potentially impact drinking water quality by affecting water catchments, storage reservoirs, the performance of water treatment processes or the integrity of distribution systems. Drinking water guidelines, such as the Australian Drinking Water Guidelines and the World Health Organization Guidelines for Drinking-water Quality, provide guidance for the safe management of drinking water. These documents present principles and strategies for managing risks that may be posed to drinking water quality. While these principles and strategies are applicable to all types of water quality risks, very little specific attention has been paid to the management of extreme weather events. We present a review of recent literature on water quality impacts of extreme weather events and consider practical opportunities for improved guidance for water managers. We conclude that there is a case for an enhanced focus on the management of water quality impacts from extreme weather events in future revisions of water quality guidance documents.

  10. Why behavior change is difficult to sustain.

    Science.gov (United States)

    Bouton, Mark E

    2014-11-01

    Unhealthy behavior is responsible for much human disease, and a common goal of contemporary preventive medicine is therefore to encourage behavior change. However, while behavior change often seems easy in the short run, it can be difficult to sustain. This article provides a selective review of research from the basic learning and behavior laboratory that provides some insight into why. The research suggests that methods used to create behavior change (including extinction, counterconditioning, punishment, reinforcement of alternative behavior, and abstinence reinforcement) tend to inhibit, rather than erase, the original behavior. Importantly, the inhibition, and thus behavior change more generally, is often specific to the "context" in which it is learned. In support of this view, the article discusses a number of lapse and relapse phenomena that occur after behavior has been changed (renewal, spontaneous recovery, reinstatement, rapid reacquisition, and resurgence). The findings suggest that changing a behavior can be an inherently unstable and unsteady process; frequent lapses should be expected. In the long run, behavior-change therapies might benefit from paying attention to the context in which behavior change occurs.

    The UK is a high prevalence country for underage alcohol use. We conducted an evidence synthesis to examine (1) the changing trends in underage drinking in the UK compared to Europe and the USA, (2) the impact of underage drinking in terms of hospital admissions, (3) the association between underage drinking and violent youth offending, and (4) the evidence base for the effectiveness of alcohol harm reduction interventions aimed at children and adolescents under the age of 18 years. The following databases were searched from November 2002 until November 2012: Cochrane Database of Systematic Reviews, National Institute for Health and Clinical Excellence, The Evidence for Policy and Practice Information, DARE, Medline, The Campbell Collaboration, CINAHL, Criminal Justice Abstracts, Psych INFO and Social Care Online. Our findings revealed changes in the way children drink in the UK and how much they drink. Alcohol related harms are increasing in the UK despite overall population levels of consumption reducing in this age group. Girls aged 15-16 years report binge drinking and drunkenness more than boys. Girls are also more likely than boys to be admitted to hospital for alcohol related harm. The evidence suggests a strong association between heavy episodic binge drinking and violent youth offending. Only 7 out of 45 randomised controlled trials (RCTs) identified for this review included children and adolescents under the age of 18 years. Most were delivered in the emergency department (ED) and involved a brief intervention. All were characterised by a wide age range of participants, heterogeneous samples and high rates of refusal and attrition. The authors conclude that whilst the ED might be the best place to identify children and adolescents at risk of harm related to alcohol use it might not be the best place to deliver an intervention. Issues related to a lack of engagement with alcohol harm reduction interventions have been previously overlooked and warrant

    Theory and empirical evidence suggest that North American-based measures of self-esteem, which measure individualistic positive self-regard, may be less applicable to Eastern cultures. In the present exploratory study, we examined how different conceptualizations of self-esteem, as measured by the Rosenberg Self-esteem Scale and the Collective Self-esteem (CSE) Scale, predicted drinking behavior among three groups of American college students (N=326) with varying ethnicities: White, Korean, and Chinese/Taiwanese. Hierarchical negative binomial regression was employed to evaluate these relations. Ethnic identity was controlled for in all analyses. Findings indicated that while global self-esteem was positively associated with drinking for the whole sample, ethnicity moderated this relationship such that global self-esteem was related to drinking for White participants but not for their Chinese/Taiwanese counterparts. In addition, while CSE did not associate with drinking for the whole sample, effects emerged for specific ethnicities. Specifically, private CSE was associated with less drinking for Korean and Chinese/Taiwanese participants. Depending on specific Asian ethnicity, public CSE served as a risk (Korean participants) or a protective factor (Chinese/Taiwanese participants) for drinking. Findings suggest that above and beyond ethnic identity, differential relationships between facets of self-esteem and drinking behavior may exist among White, Korean, and Chinese/Taiwanese young adults. Intervention and prevention programs should develop strategies to help Chinese/Taiwanese and Korean American young adults cultivate protective factors within domains of CSE.

    2011-04-12

    Background: Drinking water from natural sources in coastal Bangladesh has become contaminated by varying degrees of salinity due to saltwater intrusion from rising sea levels, cyclone and storm surges and upstream withdrawal of freshwater. Objective: Our objective was to estimate salt intake from drinking water sources and examine environmental factors that may explain a seasonal excess of hypertension in pregnancy. Methods: Water salinity data (1998-2000) for Dacope, in rural coastal Bangladesh, were obtained from the Centre for Environment and Geographic Information System. Information on drinking water sources, 24-hour urine samples and blood pressure were obtained from 343 pregnant Dacope women during the dry season (October 2009 - March 2010). The hospital-based prevalence of hypertension in pregnancy was determined for 969 pregnant women (July 2008 - March 2010). Results: Average estimated sodium intakes from drinking water ranged from 5 to 16 g/day in the dry season, compared to 0.6 - 1.2 g/day in the rainy season. Average daily sodium excretion in urine was 3.4 g/day (range 0.4 - 7.7 g/d). Women who drank shallow tubewell water were more likely to have urine sodium > 100 mmol/d than women who drank rainwater (OR=2.05, 95% CI: 1.11 - 3.80). The annual hospital prevalence of hypertension in pregnancy was higher in the dry season (12.2%, 95% CI: 9.5 - 14.8) than the rainy season (5.1%, 95% CI: 2.91 - 7.26). Conclusions: The estimated salt intake from drinking water in this population exceeded recommended limits. The problem of saline intrusion into drinking water has multiple causes and is likely to be exacerbated by climate change induced sea-level rise.

    Since brain metabolism is accompanied by heat production, measurement of brain temperature offers a method for assessing global alterations in metabolic neural activity. This approach, high-resolution (5-s bin) temperature recording from the nucleus accumbens (NAcc), temporal muscle, and facial skin, was used to study motivated drinking behavior in rats. Experienced animals were presented with a cup containing 5-ml of Coca-Cola(R) (Coke) beverage that resulted, within certain latencies, in initiation of a continuous chain of licking until all liquid was fully consumed. While cup presentation induced rapid, gradual NAcc temperature increase peaking at the start of drinking, temperatures slowly decreased during Coke consumption, but phasically increased again in the post-consumption period when rats were hyperactive, showing multiple interactions with an empty cup. Muscle temperatures followed a similar pattern, but the changes were weaker and delayed compared to those in the brain. Skin temperature rapidly dropped after cup presentation, steadily maintained at low levels during consumption, and slowly restored during the post-consumption period. Substitution of the expected Coke with either sugar-free Diet Coke(R) or water resulted in numerous drinking attempts but ultimately no consumption. During these tests, locomotor activation was much greater and more prolonged, brain and muscle temperatures increased monophasically, and their elevation was significantly greater than that with regular Coke tests. Food deprivation decreased drinking latencies, did not change the pattern of temperature fluctuations during Coke consumption, but temperature elevations were greater than in controls. Our data suggest sustained neural activation triggered by appetitive stimuli and associated with activational (seeking) aspects of appetitive motivated behavior. This seeking-related activation is rapidly ceased following consumption, suggesting this change as a neural correlate of

    Background Alcohol dependence (AD) is a complex disorder characterized by impaired control over drinking.It is determined by both genetic and environmental factors.The recent approach of genome-wide association study (GWAS)is a powerful tool for identifying complex disease-associated susceptibility alleles,however,a few GWASs have been conducted for AD,and their results are largely inconsistent.The present study aimed to screen the loci associated with alcohol-related phenotypes using GWAS technology.Methods A genome-wide association study with the behavior of regular alcohol drinking and alcohol consumption was performed to identify susceptibility genes associated with AD,using the Affymetrix 500K SNP array in an initial sample consisting of 904 unrelated Caucasian subjects.Then,the initial results in GWAS were replicated in three independent samples:1972 Caucasians in 593 nuclear families,761 unrelated Caucasian subjects,and 2955 unrelated Chinese Hans.Results Several genes were associated with the alcohol-related phenotypes at the genome-wide significance level,with the ankyrin repeat domain 7 gene (ANKRD7) showing the strongest statistical evidence for regular alcohol drinking and suggestive statistical evidence for alcohol consumption.In addition,certain haplotypes within the ANKRD7 and cytokine-like1 (CYTL 1) genes were significantly associated with regular drinking behavior,such as one ANKRD7 block composed of the SNPs rs6466686-rs4295599-rs12531086 (P =6.51 ×10-8).The association of alcohol consumption was successfully replicated with rs4295599 in ANKRD7 gene in independent Caucasian nuclear families and independent unrelated Chinese Hans,and with rs16836497 in CYTL1 gene in independent unrelated Caucasians.Meta-analyses based on both the GWAS and replication samples further supported the observed significant associations between the ANKRD7or CYTL 1 gene and alcohol consumption.Conclusion The evidence suggests that ANKRD7 and CYTL1 genes may play an

    Research has demonstrated that social image factors play an important role in the course of adolescent's substance use, that is, smoking and drinking. The concept of social images or prototypes is embedded into a theoretical model called the prototype/willingness model. The present study addresses the relative value of the prototype/willingness model in relation to the theory of planned behavior. To study relations between prototypes and adolescents' willingness and intention to engage in smoking and drinking behavior, cross-sectional data among 2814 adolescents (12-16 years) were gathered. Results show that adolescents describe daily-smoking and weekly-drinking peers generally as slightly well adjusted, slightly rebellious, not really cool, and not really attractive. Positive relations were observed between smoker and drinker prototypes and adolescents' intention and willingness to smoke and drink in the future. Furthermore, regression analyses showed that prototypes of daily-smoking and weekly-drinking peers explained a significant part of the variance in intention and willingness to smoke and drink, and added significantly to the variance explained by the variables of the theory of planned behavior.

    It has been hypothesized that Laestadianism has contributed to the less drinking observed among indigenous Sami. This paper further investigates the bivariate protective influence of Sami ethnicity on youth drinking behavior using logistic regressions. We simultaneously controlled for the influence of religious revival movements (Laestadianism or evangelic) and religious importance (being personally Christian), in addition to socio-demographics and parental factors. Cross-sectional data from the 1994/95 North Norwegian Youth Study including 2,950 (675 Sami) 15-19 year-old high school students (RR: 85%) was used. Sami ethnicity was statistically significant for two out of six alcohol outcome measures, after adjustment for religiosity and other covariates, indicating less current drinking and party drinking. Religiousness was associated with higher youth and parental abstinence across ethnicities. Generally, stronger protective influences on drinking behavior were found for religious importance (being personally Christian) than religious affiliation (Laestadianism). The non-significance between Sami and non-Sami drinking may partly be explained by ethnic differences in religiosity, but also socio-demographics (e.g., residing in the Sami Highland) and parental factors (e.g., abstinence) contributed to such a result. Laestadianism`s profound impact on Sami culture, and its strong anti-alcohol norms may have contributed to a religious-socio-cultural context of abstinence.

    Objective To examine soda consumption and aggressive behaviors, attention problems, and withdrawn behavior among five-year-old children. Study design The Fragile Families and Child Wellbeing Study is a prospective birth cohort study that follows a sample of mother-child pairs from 20 large cities in the US. Mothers reported children’s behaviors using the Child Behavior Checklist (CBCL) at age 5 and were asked to report how many servings of soda the child drinks on a typical day. Results In the sample of 2929 children, 52% were boys, 51% were African-American 43% consumed at least one serving of soda per day and 4% consumed 4 or more servings per day. In analyses adjusted for socio-demographic factors, consuming one (Beta 0.7 95% CI 0.1,1.4), two (Beta 1.8 95%CI 0.8,2.7), three (Beta 2.0 95%CI 0.6,3.4) or four or more (Beta 4.7 95%CI 3.2,6.2) servings was associated with a higher aggressive behavior score compared with consuming no soda. Furthermore, those who consumed four or more (Beta 1.7 95%CI 1.0,2.4) soda servings had higher scores on the attention problems subscale. Higher withdrawn behavior scores were noted among those consuming two (Beta 1.0 95%CI 0.3,1.8), or four or more (Beta 2.0 95%CI 0.8,3.1) soda servings compared with those who consumed no soda. Conclusion We note an association between soda consumption and negative behavior among very young children; future studies should explore potential mechanisms that could explain this association.

    Full Text Available Objective: In an attempt to reduce high levels of traffic crashes, a new legislation was approved in Brazil in 2008. This study aimed to assess behavioral change among drivers who had drunk at alcohol outlets (AO after implementation of the law. Method: A three-stage probability sampling survey was conducted in Porto Alegre, state of Rio Grande do Sul, Brazil. Individuals seen leaving AOs after drinking were approached (n=3,018. Selected drivers (n=683 answered a structured interview, were breathalyzed, and had saliva specimens collected for drug screening. Results: Overall, 60.3% (SE 4.5 of drivers reported they did not change their behavior. Among those who reported behavioral changes, most reported drinking less as their main strategy toward safer driving behavior. Variables independently associated with behavior change included having drunk at a high outlet density area (odds ratio [OR] 1.7 [1.1-2.8] and having a favorable opinion about the law (OR 4.3 [2.1-8.9]. Conclusions: Our findings suggest that awareness of the law has not been enough to promote behavioral change. As most drivers had a favorable opinion of the law and this variable was found to be the strongest predictor of behavior change, efforts to better integrate education and enforcement seem to be pivotal and might be well received by the population.

  5. Monitoring microbiological changes in drinking water systems using a fast and reproducible flow cytometric method

    Prest, Emmanuelle I E C

    2013-12-01

    Flow cytometry (FCM) is a rapid, cultivation-independent tool to assess and evaluate bacteriological quality and biological stability of water. Here we demonstrate that a stringent, reproducible staining protocol combined with fixed FCM operational and gating settings is essential for reliable quantification of bacteria and detection of changes in aquatic bacterial communities. Triplicate measurements of diverse water samples with this protocol typically showed relative standard deviation values and 95% confidence interval values below 2.5% on all the main FCM parameters. We propose a straightforward and instrument-independent method for the characterization of water samples based on the combination of bacterial cell concentration and fluorescence distribution. Analysis of the fluorescence distribution (or so-called fluorescence fingerprint) was accomplished firstly through a direct comparison of the raw FCM data and subsequently simplified by quantifying the percentage of large and brightly fluorescent high nucleic acid (HNA) content bacteria in each sample. Our approach enables fast differentiation of dissimilar bacterial communities (less than 15min from sampling to final result), and allows accurate detection of even small changes in aquatic environments (detection above 3% change). Demonstrative studies on (a) indigenous bacterial growth in water, (b) contamination of drinking water with wastewater, (c) household drinking water stagnation and (d) mixing of two drinking water types, univocally showed that this FCM approach enables detection and quantification of relevant bacterial water quality changes with high sensitivity. This approach has the potential to be used as a new tool for application in the drinking water field, e.g. for rapid screening of the microbial water quality and stability during water treatment and distribution in networks and premise plumbing. © 2013 Elsevier Ltd.

    Full Text Available Acquired behavioral changes have essentially been described in advanced multiple sclerosis (MS. The present study was designed to determine whether behavioral modifications specifically related to the MS pathological process could be identified in the initial phase of the disease, as compared to control patients with chronic, relapsing and progressive inflammatory disorders not involving the central nervous system (CNS. Eighty-eight early MS patients (Expanded Disability Status Scale score ≤ 2.5 and 48 controls were tested. Perceived changes by informants in behavioral control, goal-directed behavior, decision making, emotional expression, insight and interpersonal relationships were assessed using the Iowa Scale of Personality Change (ISPC. Executive behavioral disturbances were screened using the Dysexecutive Questionnaire (DEX. The mean change between the premorbid and postmorbid ISPC ratings was similar in the MS [12.2 (SD 15.6] and in the control [11.5 (SD 15.1] group. The perceived behavioral changes (PBCs most frequently reported in both groups were lack of stamina, lability/moodiness, anxiety, vulnerability to stress and irritability. Pathological scores in the DEX were also similar in both groups. Correlations between PBCs and DEX scores were different in MS and control groups. MS patients with cognitive impairment had a marginally higher number of PBCs than control patients (p = 0.056 and a significantly higher DEXp score (p = 0.04. These results suggest that (1 PBCs occurring in early MS patients were not different from those induced by comparable chronic non-CNS disorders, (2 qualitative differences in the relationship between behavioral symptoms and executive-behavioral changes may exist between MS and control groups, and (3 behavioral symptoms seem associated with cognitive deficits in MS. We further plan to assess these observations longitudinally.

    College students continue to report being disrupted by other students’ alcohol use. Objective: This study was designed to develop measures to document the consequences resulting from other students’ drinking and identify differences in experiencing these consequences by student characteristics and drinking behaviors. Study group: A stratified random sample of undergraduate students (N = 3,908) from ten universities in North Carolina, USA, completed a web-based assessment. Methods: Exploratory factor analysis (EFA) was performed on the random first split-half sample (n = 1,954) to identify factor structure. Confirmatory factor analysis (CFA) was performed on the remaining half sample (n = 1,954) using structural equation modeling. Results: EFA revealed two inventories: interpersonal and community consequences of others’ drinking inventories. CFA on the second split-half sample identified model fits for the two factor structure suggested by EFA. Of 3,908 participants, 78% reported experiencing one or more consequences due to others’ drinking during the past 30 days. Multivariable generalized linear mixed modeling further validated the inventories and resulted in several associations. Male students who reported getting drunk experienced significantly more interpersonal consequences from others’ drinking (p < .001). Minority students, students who lived on campus and students who reported getting drunk experienced significantly more community consequences from others’ drinking (p < .01). Conclusions: These findings demonstrate that 4 out of 5 college students experience consequences from others’ drinking, and consequences vary for different subgroups of students. Although these inventories should be tested further, these findings propose standardized measures that may be useful to assess the consequences of others’ drinking among college students.

    Full Text Available Background. The aim of this research was to observe the changes which take place in the electrophoretic picture of milk proteins after pasteurisation and inoculation with different starter cultures (both traditional and probiotic. After incubation, the yoghurt, kefir, acidified milk, fermented Bifidobacterium bifidum drink and Lactobacillus acidophillus drink were chilled for 14 days to observe the changes which occurred. Materials and methods. The research materials were raw and pasteurised milk, as well as fermented milk- based drinks. The raw milk used for research came from Polish Holstein-Fresian black and white cows. The milk was sampled 3 times and divided into 5 parts, each of which was pasteurised at 95°C for 10 min and then cooled for inoculation: yoghurt to 45°C, kefir and acidified milk to 22°C and drinks with Bifidobacterium bifidum and Lactobacillus acidophillus to 38°C. Milk was inoculated with lyophilised, direct vat starter cul- tures, in an amount equal to 2% of the working starter. For the production of fermented drinks, the subsequent starters were applied: “YC-180” Christian Hansen for yoghurt, “D” Biolacta-Texel-Rhodia for kefir, CH-N--11 Christian Hansen for acidified milk, starter by Christian Hansen for the probiotic Bifidobacterium bifidum milk, starter by Biolacta-Texel-Rhodia for the probiotic Lactobacillus acidophillus milk. The analyses were conducted in raw, pasteurised and freshly fermented milk as well as in milk drinks stored for 14 days. The total solid content was estimated by the drying method; the fat content by the Gerber method; the lactose content by the Bertrand method; the protein content by the Kjeldahl method with Buchi apparatus; the density of milk was measured with lactodensimeter; acidity with a pH-meter; and potential acidity by Soxhlet-Henkl method (AOAC, 1990.

    Examining individual characteristics may not yield an understanding of the complex array of factors that affect college student alcohol use. Utilizing a latent class analysis, the present study investigated an alcohol and drug use database of first-year college students at 89 U.S. colleges and universities (N = 21,945). These data were collected between December, 2010 and September, 2011. This study identified: (1) classes based on alcohol consumption, alcohol-related behaviors, and past-year use of illegal drugs and nonmedical use of prescriptions medications (NMUPM); (2) demographic covariates of these classes; and (3) differential social norms awareness, perceived harmfulness of illegal drugs and NMUPM, and protective strategies. Four classes were identified: (1) Low Risk Drinking/Low Prevalence Drug Use (Class 1); (2) Lower Intake Drinking/Moderate Prevalence Drug Use (Class 2); (3) Moderate Risk Drinking/Moderate Prevalence Drug Use (Class 3); and (4) High Risk Drinking/High Prevalence Drug Use (Class 4). Classes differed in self-reported typical week drinking, estimated peak blood alcohol content over the past 2 weeks, high-risk alcohol use, negative alcohol-related consequences, driving under the influence or riding with drinking drivers, alcohol-related protective behaviors, and past-year substance use. Of particular interest was the identification of a latent class (Class 2) composed primarily of females with a relatively low alcohol intake, but with a high probability of past-year other substance use. This group reported negative alcohol-related consequences despite their relatively low intake. To our knowledge, this is the first latent class analysis of college student alcohol use that includes a drug use indicator and compares social norms awareness, harmfulness perceptions, and alcohol-related protective behaviors between classes.

    2012-01-01

    We investigated whether a thoroughly personalized message (tailored to a person's "Big Five" personality traits) or a message matched to an alternate form of self-schema (ideal self-schema) would be more influential than a self-schema matched message (that has been found to be effective) at marketing responsible drinking. We expected the more thoroughly personalized Big Five matched message to be more effective than the self-schema matched message. However, neither the Big Five message nor the ideal self-schema message was more effective than the actual self-schema message. Therefore, research examining self-schema matching should be pursued rather than more complex Big Five matching.

    Previous research has provided considerable support for idea that increased parental support and control are strong determinants of lower prevalence levels of adolescent risk behavior. Much less is known on the association between specific parenting practices, such as concrete rules with respect to smoking and drinking and adolescent risk behavior. The present paper examined whether such concrete parental rules (1) have an effect on the targeted behaviors and (2) predict other, frequently co-occurring, risk behaviors (i.e., cannabis use and early sexual intercourse). These hypotheses were tested in a nationally representative sample of 12- to 16-year-old adolescents in the Netherlands. We found that both types of rules were associated with a lower prevalence of the targeted behaviors (i.e., smoking and drinking). In addition, independent of adolescent smoking and drinking behaviors, parental rules on smoking predicted a lower prevalence of cannabis use and early sexual intercourse, and parental rules on alcohol use also predicted a lower prevalence of early sexual intercourse. This study showed that concrete parental rule setting is more strongly related to lower levels of risk behaviors in adolescents compared to the more general parenting practices (i.e., support and control). Additionally, the effects of such rules do not only apply to the targeted behavior but extend to related behaviors as well. These findings are relevant to the public health domain and suggest that a single intervention program that addresses a limited number of concrete parenting practices, in combination with traditional support and control practices, may be effective in reducing risk behaviors in adolescence.

    OBJECTIVE To analyze oral health behaviors changes over time in Brazilian adolescents concerning maternal educational inequalities. METHODS Data from the Pesquisa Nacional de Saúde do Escolar (Brazilian National School Health Survey) were analyzed. The sample was composed of 60,973 and 61,145 students from 26 Brazilian state capitals and the Federal District in 2009 and 2012, respectively. The analyzed factors were oral health behaviors (toothbrushing frequency, sweets consumption, soft drink consumption, and cigarette experimentation) and sociodemographics (age, sex, race, type of school and maternal schooling). Oral health behaviors and sociodemographic factors in the two years were compared (Rao-Scott test) and relative and absolute measures of socioeconomic inequalities in health were estimated (slope index of inequality and relative concentration index), using maternal education as a socioeconomic indicator, expressed in number of years of study (> 11; 9-11; ≤ 8). RESULTS Results from 2012, when compared with those from 2009, for all maternal education categories, showed that the proportion of people with low toothbrushing frequency increased, and that consumption of sweets and soft drinks and cigarette experimentation decreased. In private schools, positive slope index of inequality and relative concentration index indicated higher soft drink consumption in 2012 and higher cigarette experimentation in both years among students who reported greater maternal schooling, with no significant change in inequalities. In public schools, negative slope index of inequality and relative concentration index indicated higher soft drink consumption among students who reported lower maternal schooling in both years, with no significant change overtime. The positive relative concentration index indicated inequality in 2009 for cigarette experimentation, with a higher prevalence among students who reported greater maternal schooling.

    Objective To investigate the correlation between drinking behavior combined with polymorphisms of extracellular superoxide dismutase (EC-SOD) and aldehyde dehydrogenase-2 (ALDH2) genes and pancreatic cancer. Methods The genetic polymorphisms of EC-SOD and ALDH2 were analyzed by polymerase chain reaction restriction fragment length polymorphism in the peripheral blood leukocytes obtained from 680 pancreatic cancer cases and 680 non-cancer controls. Subsequently the frequency of genotype was compared between the pancreatic cancer patients and the healthy controls.The relationship of drinking with pancreatic cancer was analyzed. Results The frequencies of EC-SOD (C/G) and ALDH2 variant genotypes were 37.35% and 68.82%respectively in the pancreatic cancer cases, and were significantly higher than those in the healthy controls (21.03% and 44.56%, all P Conclusion EC-SOD (C/G), ALDH2 variant genotypes and drinking might be the risk factors of pancreatic cancer.

    Cryptosporidium concentrations as estimated by the meta-analysis, but when DWIs were influenced by agricultural runoff or wildlife, there was a poor relationship. Average recovery values were available for 6 out of 22 Cryptosporidium concentration data sets and concomitant analysis demonstrated no changes in trends, with and without correction. Nevertheless, recovery assays performed along with every oocyst count would have enhanced the precision of this work. Based on our findings, the use of annual averages of E. coli concentrations as a surrogate for Cryptosporidium concentrations can result in an inaccurate estimate of the Cryptosporidium risk for agriculture impacted drinking water intakes or for intakes with more distant wastewater sources. Studies of upstream fecal pollution sources are recommended for drinking water suppliers to improve their interpretation of source water quality data.

    Although benzene is an important occupational health hazard and a carcinogen, the possibility that behavioral changes may forewarn of the later-occurring hematological changes has not been investigated. A time-sampling protocol was used to quantify the occurrence of 7 categories of behavior in the homecage following daily 6-hr exposures to two strains of adult mice (CD1 and C57BL/6J). The behavioral categories were stereotypic behavior, sleeping, resting, eating, grooming, locomotion, and fighting. The inhalation exposures were designed to reflect occupational exposure. Dynamic vapor exposure techniques in standard inhalation chambers were employed. Exposure to 300 or 900 ppm benzene increased the occurrence of eating and grooming and reduced the number of mice that were sleeping or resting. The responses to benzene of both the CD1 and the C57 strains were similar. The positive findings with benzene inhalation indicate the utility of behavioral investigations into the toxicology of inhaled organic solvents. The methods described herein illustrate an objective observation of animal behavior that is capable of documenting toxicity and of guiding detailed follow-up studies aimed at mechanism of action.

    Background The probabilistic discrete event systems (PDES) method provides a promising approach to study dynamics of underage drinking using cross-sectional data. However, the utility of this approach is often limited because the constructed PDES model is often non-identifiable. The purpose of the current study is to attempt a new method to solve the model. Methods A PDES-based model of alcohol use behavior was developed with four progression stages (never-drinkers [ND], light/moderate-drinker [LMD], heavy-drinker [HD], and ex-drinker [XD]) linked with 13 possible transition paths. We tested the proposed model with data for participants aged 12–21 from the 2012 National Survey on Drug Use and Health (NSDUH). The Moore-Penrose (M-P) generalized inverse matrix method was applied to solve the proposed model. Results Annual transitional probabilities by age groups for the 13 drinking progression pathways were successfully estimated with the M-P generalized inverse matrix approach. Result from our analysis indicates an inverse “J” shape curve characterizing pattern of experimental use of alcohol from adolescence to young adulthood. We also observed a dramatic increase for the initiation of LMD and HD after age 18 and a sharp decline in quitting light and heavy drinking. Conclusion Our findings are consistent with the developmental perspective regarding the dynamics of underage drinking, demonstrating the utility of the M-P method in obtaining a unique solution for the partially-observed PDES drinking behavior model. The M-P approach we tested in this study will facilitate the use of the PDES approach to examine many health behaviors with the widely available cross-sectional data. PMID:26511344

    To help health educators build upon the best of different health behavior change theories, this paper offers a unified set of instructional design strategies for health education interventions. This set draws upon the recommendations of Rosenstock (Health Belief Model), Bandura (Social Cognitive Theory), and Dearing (Diffusion Theory), and uses a modified Events of Instruction framework (adapted from Robert Gagne): gain attention (convey health threats and benefits), present stimulus material (tailor message to audience knowledge and values, demonstrate observable effectiveness, make behaviors easy-to-understand and do), provide guidance (use trustworthy models to demonstrate), elicit performance and provide feedback (to enhance trialability, develop proficiency and self-efficacy), enhance retention and transfer (provide social supports and deliver behavioral cues). Sample applications of these strategies are provided. A brief review of research on adolescent smoking prevention enables consideration of the frequency with which these strategies are used, and possible patterns between strategy use and behavioral outcomes.

    Scientists have established that climate change threatens sources of drinking water through many different pathways, both in terms of quantity and quality. Recognizing water utilities will face the brunt of these impacts, this study seeks to better understand the disconnect between the projections produced and the needs of utilities on-the-ground. As part of the first stage of the three-year study, this presentation reports results of a statewide survey evaluating how far along water utilities in California are along in preparing for the projected climate change impacts on water quality, the range in respondents' perspectives (and concerns) of climate change on water quality, and how the state's four-year drought is already presenting treatment challenges. On-going case studies are investigating the needs and capacity of utilities to prepare for and adapt to the projected water quality impacts from increasing extreme events and how or whether climate scientists can help meet these needs.

    The purpose of this study is to examine how parental drinking behavior, drinking locations, alcohol outlet density, and types of social support (tangible, emotional, and social companionship) may place children at greater risk for physical abuse. Data on use of physical abuse, drinking behaviors, types of social support, social networks, and demographic information were collected via telephone interviews with 3,023 parent respondents in 50 cities in California. Data on alcohol outlet density were obtained by the California Department of Alcoholic Beverage Control. Multilevel Poisson models were used to analyze data for the drinking levels in the entire sample and dose-response drinking models for drinkers. Social companionship support was related to more frequent use of physical abuse. Having a higher percentage of social companionship support network living within the neighborhood was related to more frequent physical abuse in the full sample. This relationship was moderated by on-premise alcohol outlet density. With regards to drinking behaviors, drinking behaviors from ex-drinkers to frequent heavy drinkers used physically abusive parenting practices more often than lifetime abstainers. The dose-response models show that each additional drinking event at a bar or home/party was related to more frequent use of physical abuse. Practitioners working with parents who abuse their children should be aware that not all social support is beneficial. Findings build evidence that child maltreatment is influenced by the interaction between individual and ecological factors.

    We investigated the behavioral effects of exposure to waterborne phytoestrogens in male fighting fish, Betta splendens. Adult fish were exposed to a range of concentrations of genistein, equol, {beta}-sitosterol, and the positive control 17{beta}-estradiol. The following behaviors were measured: spontaneous swimming activity, latency to respond to a perceived intruder (mirror reflection), intensity of aggressive response toward a perceived intruder, probability of constructing a nest in the presence of a female, and the size of the nest constructed. We found few changes in spontaneous swimming activity, the latency to respond to the mirror, and nest size, and modest changes in the probability of constructing a nest. There were significant decreases, however, in the intensity of aggressive behavior toward the mirror following exposure to several concentrations, including environmentally relevant ones, of 17{beta}-estradiol, genistein, and equol. This suggests that phytoestrogen contamination has the potential to significantly affect the behavior of free-living fishes. - Environmentally relevant concentrations of phytoestrogens reduce aggressive behavior in fish.

    We aimed to examine the changes in sugar-sweetened soft drink intake across the Capital Region of Denmark from 2007 to 2013 and to examine the association between intake and neighbourhood socioeconomic status. The study included data from three health surveys in 2007 (n = 30,426), 2010 (n = 42,218) and 2013 (n = 34,330) in the Capital Region of Denmark. Frequency of soft drink intake was derived from questionnaires among residents aged 25-79 years and linked with information from central registers. Municipality social groups (MSG) 1-4 of decreasing affluence were defined as a composite measure. Logistic regression analyses were conducted for individuals with an appropriate soft drink intake (intake (≥ 3 times/week). The proportion of individuals reporting an appropriate soft drink intake increased by 71% during 2007-2013 (p intake. Compared to MSG 1, odds of an appropriate soft drink intake were significantly lower in MSG 3-4: OR = 0.87 (95%CI 0.83-0.91) and OR = 0.89 (95%CI 0.85-0.92), respectively. Compared to MSG 1, odds of a frequent soft drink intake were significantly higher in MSG 3-4: OR = 1.24 (95%CI 1.63-1.31) and 1.17 (95%CI 1.10-1.25), respectively. A significant interaction between MSG and educational level was found among individuals reporting a frequent soft drink intake (p = 0.02). The results show an encouraging reduction in frequency of soft drink intake among capital residents in the period of 2007-2013. A social gradient was observed in soft drink intake across MSG.

    Full Text Available In a survey conducted by the Brazilian Institute of Geography and Statistics (IBGE (2010, the Northeast region of Brazil configured as the lowest per capita consumers of soda as compared to other regions in the country; and the state of Bahia was in 6TH place among the northeastern states. Thus, Salvador (Bahia is in the ranking of the capitals that least consumes this kind of drink. In a literature review, Souki, Christino, and Pereira (2005, show that, despite the economic importance of the industry of soft drinks in Brazil, there are rarely scientific incursions on the behavior of consumers of these products, leaving us with little information about this theme. From that, the present study was developed with the objective of understanding and characterizing the behavior of consumer purchasing “soteropolitano” of soft drinks, identifying their consumption habits and decisions that are taken at the time of purchase of the product, the reference groups, and the attributes considered important in their purchase decision. For both, a descriptive survey was carried out, with quantitative variables, totaling 429 personal interviews in different neighborhoods of Salvador, in places with a large flow of people, such as educational institutions and public spaces. It was found that most of the interviewees choose which soft drink to buy based on their experiences. We did observe a mild influence of characteristics of groups on the decision to purchase the product. However, in relation to the attributes of the soft drink, it was found that the flavor, the brand, and price are the attributes considered most decisive by interviewees in their purchase decision.

    Full Text Available This paper introduces the main changes in the distribution of food and drinks in Argentina, which began with the economic, political and social crisis in 2001. The territory used by some of the social actors involved, such as businesses of different sizes (supermarkets and neighborhood stores and people (consumers, will no longer respond exclusively to a global order or to territorial verticalities. Many of these new tendencies will be led by local norms connected with territorial horizontalities. The most important of these changes is the fact that consumption has become oriented towards: sales, smaller packaging, second and third brands, supermarkets' own brands, new shopping frequencies, a combination of several distribution channels with the so-called "back-to-the-neighborhood" phenomenon, and single-item shopping.

    Fluorescence excitation emission matrices-parallel factor analysis (EEM-PARAFAC) is a powerful tool for characterizing dissolved organic matter (DOM), and it is applied in a rapidly growing number of studies on drinking water and wastewater treatments. This paper presents an overview of recent findings about the occurrence and behavior of PARAFAC components in drinking water and wastewater treatments, as well as their feasibility for assessing the treatment performance and water quality including disinfection by-product formation potentials (DBPs FPs). A variety of humic-like, protein-like, and unique (e.g., pyrene-like) fluorescent components have been identified, providing valuable insights into the chemical composition of DOM and the effects of various treatment processes in engineered systems. Coagulation/flocculation-clarification preferentially removes humic-like components, and additional treatments such as biological activated carbon filtration, anion exchange, and UV irradiation can further remove DOM from drinking water. In contrast, biological treatments are more effective for protein-like components in wastewater treatments. PARAFAC components have been proven to be valuable as surrogates for conventional water quality parameter, to track the changes of organic matter quantity and quality in drinking water and wastewater treatments. They are also feasible for assessing formations of trihalomethanes and other DBPs and evaluating treatment system performance. Further studies of EEM-PARAFAC for assessing the effects of the raw water quality and variable treatment conditions on the removal of DOM, and the formation potentials of various emerging DBPs, are essential for optimizing the treatment processes to ensure treated water quality.

    Effective, sustainable safety incentives are integrated into a performance management system designed to encourage long term behavior change. Effective incentive program design integrates the fundamental considerations of compensation (i.e., valence, instrumentality, expectancy, equity) with behavior change theory in the context of a strong merit based performance management system. Clear expectations are established and communicated from the time applicants apply for the position. Feedback and social recognition are leveraged and used as rewards, in addition to financial incentives built into the compensation system and offered periodically as short term incentives. Rewards are tied to specific objectives intended to influence specific behaviors. Objectives are designed to challenge employees, providing opportunities to grow and enhance their sense of belonging. Safety contests and other awareness activities are most effective when used to focus safety improvement efforts on specific behaviors or processes, for a predetermined period of time, in the context of a comprehensive safety system. Safety incentive programs designed around injury outcomes can result in unintended, and undesirable, consequences. Safety performance can be leveraged by integrating safety into corporate cultural indicators. Symbols of safety remind employees of corporate safety goals and objectives (e.g., posted safety goals and integrating safety into corporate mission and vision). Rites and ceremonies provide opportunities for social recognition and feedback and demonstrate safety is a corporate value. Feedback opportunities, rewards, and social recognition all provide content for corporate legends, those stories embellished over time, that punctuate the overall system of organizational norms, and provide examples of the organizational safety culture in action.

    OBJECTIVES: Adenosine signaling has been implicated in the pathophysiology of several psychiatric disorders including alcoholism, depression, and anxiety. Adenosine levels are controlled in part by transport across the cell membrane by equilibrative nucleoside transporters (ENTs). Recent evidence showed that a polymorphism in the gene encoding ENT1 is associated with comorbid depression and alcoholism in women. We have previously shown that deletion of ENT1 reduces ethanol intoxication and elevates alcohol intake in mice. Interestingly, ENT1 null mice display decreased anxiety-like behavior compared to wild-type littermates. However, our behavioral studies were performed only in male mice. Here, we extend our research to include female mice, and test the effect of ENT1 knockout on other behavioral correlates of alcohol drinking, including depressive and compulsive behavior, in mice. METHODS: To assess depression-like behavior, we used a forced swim test modified for mice. We examined anxiety-like behavior and locomotor activity in open field chambers, and perseverant behavior using the marble-burying test. Finally, we investigated alcohol consumption and preference in female mice using a two-bottle choice paradigm. RESULTS: ENT1 null mice of both sexes showed reduced immobility time in the forced swim test and increased time in the center of the open field compared to wild-type littermates. ENT1 null mice of both sexes showed similar locomotor activity levels and habituation to the open field chambers. Female ENT1 null mice displayed increased marble-burying compared to female wild-types, but no genotype difference was evident in males. Female ENT1 null mice showed increased ethanol consumption and preference compared to female wild-types. CONCLUSIONS: Our findings suggest that ENT1 contributes to several important behaviors involved in psychiatric disorders. Inhibition of ENT1 may be beneficial in treating depression and anxiety, while enhancement of ENT1 function

    Decision making is an integral part of the transtheoretical model of behavior change. Stage of change represents a temporal dimension for behavior change and has been the key dimension for integrating principles and processes of change from across leading theories of psychotherapy and behavior change. The decision-making variables representing the pros and cons of changing have been found to have systematic relationships across the stages of change for 50 health-related behaviors. Implications of these patterns of relationships are discussed in the context of helping patients make more effective decisions to decrease health risk behaviors and increase health-enhancing behaviors.

    Peer communication represents 1 mechanism through which norms are disseminated in social groups. The theory of normative social behavior (TNSB) posits that group identity, outcome expectations, and injunctive norms moderate the relation between descriptive norms and behaviors. This article extends the purview of the TNSB by conceptualizing peer communication as another moderator in the relationship between descriptive norms and behaviors. A survey was conducted among college students (N = 675) to measure their normative perceptions, peer communication, alcohol consumption, alcohol-related consequences, and intention to drink alcohol. As hypothesized, descriptive norms, peer communication, and the interaction between these two variables were significantly associated with consumption, even after controlling for known predictors of both consumption and various mechanisms of normative influences. Controlling for prior consumption, peer communication was also a significant predictor of intention to consume alcohol in the future. This model explained approximately 63% of the variance in intention. This study found a significant relationship between peer communication and alcohol drinking behaviors and intentions after controlling for perceived norms.

    2000-01-01

    Measures of (a) self-efficacy and (b) motivation to change (stage) for controlling drinking and drinking/driving were examined at the beginning and the end of a four-week intervention in a sample of 670 Driving Under the Influence (DUI) offenders in a court-mandated program. Hypotheses regarding stability of stage classifications over the course of intervention, and the relation between stage classification, stage scores, self-efficacy, and DUI recidivism were examined. Based on results of an earlier study it was expected that most offenders would be classified into the action stage at entry and that classifications would tend to remain stable from pretest to posttest. Action was the most frequent stage classification in both drinking and drinking/driving domains at both test periods, with precontemplation being the least frequent classification. When tracked over the four weeks, stage classifications for drinking and drinking/driving were stable for 74 to 89% of offenders in the two domains, respectively. As predicted, higher action and self-efficacy scores were related to lower recidivism, and action scores in the drinking/driving domain were the best early recidivism predictors among a predictor set that included traditional recidivism indicators. Drinking contemplators (i.e., those with the highest stage score on the contemplation scale) had higher recidivism rates than other drinking stage classifications. Implications for DUI intervention programs are discussed.

    Full Text Available The Paraguayan electoral process has been historically conditioned by the control of the Asociación Nacional Republicana, the dominant political party during the Stroessner’s regime and the period of transition towards democracy. For this reason, the change of political representation in the Presidency that occurred in 2008 as a result of the electoral process was a milestone in the country’s political history and it highlighted the importance of analyzing the voting behavior of the Paraguayan population, its trends and the the conjectural and structural elements that condition them. In this opportunity we review the parameters of electoral behavior present in the country’s last three general elections, considering the electoral volatility rates resulting from such elections and the effective participation levels recorded, analyzing the socio-political context in which they occurred.

    2006-06-01

    Mediational links between parenting styles (authoritative, authoritarian, permissive), impulsiveness (general control), drinking control (specific control), and alcohol use and abuse were tested. A pattern-mixture approach (for modeling non-ignorable missing data) with multiple-group structural equation models with 421 (206 female, 215 male) college students was used. Gender was examined as a potential moderator of parenting styles on control processes related to drinking. Specifically, the parent-child gender match was found to have implications for increased levels of impulsiveness (a significant mediator of parenting effects on drinking control). These findings suggest that a parent with a permissive parenting style who is the same gender as the respondent can directly influence control processes and indirectly influence alcohol use and abuse.

  19. Massage Changes Babies' Body, Brain and Behavior

    Ishikawa, Chihiro; Shiga, Takashi

    Tactile stimulation is an important factor in mother-infant interactions. Many studies on both human and animals have shown that tactile stimulation during the neonatal period has various beneficial effects in the subsequent growth of the body and brain. In particular, massage is often applied to preterm human babies as “touch care”, because tactile stimulation together with kinesthetic stimulation increases body weight, which is accompanied by behavioral development and the changes of endocrine and neural conditions. Among them, the elevation of insulin-like growth factor-1, catecholamine, and vagus nerve activity may underlie the body weight gain. Apart from the body weight gain, tactile stimulation has various effects on the nervous system and endocrine system. For example, it has been reported that tactile stimulation on human and animal babies activates parasympathetic nervous systems, while suppresses the hypothalamic-pituitary-adrenalcortical (HPA) axis, which may be related to the reduction of emotionality, anxiety-like behavior, and pain sensitivity. In addition, animal experiments have shown that tactile stimulation improves learning and memory. Facilitation of the neuronal activity and the morphological changes including the hippocampal synapse may underlie the improvement of the learning and memory. In conclusion, it has been strongly suggested that tactile stimulation in early life has beneficial effects on body, brain structure and function, which are maintained throughout life.

    Research has suggested that exposure to psychological trauma is associated with increased abuse of psychoactive substances, particularly alcohol. To assess this, we analyzed alcohol consumption, binge drinking, and alcohol dependence among a random sample of 1681 New York City adults 1 year and 2 years after the September 11 attacks. In multivariate models controlling for demographic factors, other stressor exposures, social psychological resources, and history of anti-social behavior, we found that greater exposure to the World Trade Center disaster (WTCD) was associated with greater alcohol consumption at 1 year and 2 years after this event. In addition, our analyses also indicated that exposure to the WTCD was associated with binge drinking at 1 year after but not 2 years after this event. Alcohol dependence, assessed as present in either year 1 or year 2, also was positively associated with greater WTCD exposures. Posttraumatic stress disorder was not associated with alcohol use, once WTCD exposure and other covariates were controlled. Our study suggests that exposure to psychological trauma may be associated with increases in problem drinking long after exposure and deserves further investigation. PMID:15982827

    The extraordinary growth in Internet use offers researchers important new opportunities to identify and test new ways to deliver effective behavior change programs. The information architecture (IA)-the structure of website information--is an important but often overlooked factor to consider when adapting behavioral strategies developed in office-based settings for Web delivery. Using examples and relevant perspectives from multiple disciplines, we describe a continuum of website IA designs ranging from a matrix design to the tunnel design. The free-form matrix IA design allows users free rein to use multiple hyperlinks to explore available content according to their idiosyncratic interests. The more directive tunnel IA design (commonly used in e-learning courses) guides users step-by-step through a series of Web pages that are arranged in a particular order to improve the chances of achieving a goal that is measurable and consistent. Other IA designs are also discussed, including hierarchical IA and hybrid IA designs. In the hierarchical IA design, program content is arranged in a top-down manner, which helps the user find content of interest. The more complex hybrid IA design incorporates some combination of components that use matrix, tunnel, and/or hierarchical IA designs. Each of these IA designs is discussed in terms of usability, participant engagement, and program tailoring, as well as how they might best be matched with different behavior change goals (using Web-based smoking cessation interventions as examples). Our presentation underscores the role of considering and clearly reporting the use of IA designs when creating effective Web-based interventions. We also encourage the adoption of a multidisciplinary perspective as we move towards a more mature view of Internet intervention research.

    Behavior change communication for improving handwashing with soap can be labor and resource intensive, yet quality results are difficult to achieve. Nudges are environmental cues engaging unconscious decision-making processes to prompt behavior change. In this proof-of-concept study, we developed an inexpensive set of nudges to encourage handwashing with soap after toilet use in two primary schools in rural Bangladesh. We completed direct observation of behaviors at baseline, after providing traditional handwashing infrastructure, and at multiple time periods following targeted handwashing nudges (1 day, 2 weeks, and 6 weeks). No additional handwashing education or motivational messages were completed. Handwashing with soap among school children was low at baseline (4%), increasing to 68% the day after nudges were completed and 74% at both 2 weeks and 6 weeks post intervention. Results indicate that nudge-based interventions have the potential to improve handwashing with soap among school-aged children in Bangladesh and specific areas of further inquiry are discussed.

    Underage drinking is a significant problem facing US communities. Several environmental alcohol prevention (EAP) strategies (laws, regulations, responsible beverage service training and practices) successfully address underage drinking. Communities, however, face challenges carrying out these EAP strategies effectively. This small-scale, 3-year, randomized controlled trial assessed whether providing prevention coalitions with Getting To Outcomes-Underage Drinking (GTO-UD), a tool kit and implementation support intervention, helped improve implementation of two common EAP strategies, responsible beverage service training (RBS) and compliance checks. Three coalitions in South Carolina and their RBS and compliance check programs received the 16-month GTO-UD intervention, including the GTO-UD manual, training, and onsite technical assistance, while another three in South Carolina maintained routine operations. The measures, collected at baseline and after the intervention, were a structured interview assessing how well coalitions carried out their work and a survey of merchant attitudes and practices in the six counties served by the participating coalitions. Over time, the quality of some RBS and compliance check activities improved more in GTO-UD coalitions than in the control sites. No changes in merchant practices or attitudes significantly differed between the GTO-UD and control groups, although merchants in the GTO-UD counties did significantly improve on refusing sales to minors while control merchants did not.

    2012-01-01

    We examined the link between social norms and active social influences occurring during natural social drinking contexts. Across 4 yearly measurement-bursts, college students (N = 523) reported daily for 30-day periods on drinking norms, drinking offers, how many drinks they accepted, and personal drinking levels during social drinking events. In contexts where drinking norms were higher, students were more likely to both receive and comply with drinking offers. These acute social influences were highly stable throughout college, but affected men and women differently across time: Women received more drinking offers than men, especially at the beginning of college and when norms were higher, but men complied with more drinking offers per occasion. These effects were not attributable to between-person differences in social drinking motives or drinking levels, nor to within-person patterns of situation-selection. The present work suggests that context-specific drinking norms catalyze active social influence attempts, and further promote compliance drinking.

Methods: Twenty recreational cyclists and triathletes (22.8 ± 6.9 years old were recruited. Subjects completed three laboratory sessions each (DB=23°C, RH=70% in randomly assigned order, with at least one week between sessions: one session, only water available (WAonly; another session, only sports drink (SDonly; and another session, both beverages (BOTH. Drinking was ad libitum. Each exercise session lasted 100 min.: a 20 min. warm-up, followed by eight 5-min. high-intensity intervals (85-95% HRmax alternating with 2.5 min. recovery time (60-70% HRmax and a final 20 min. recovery (60-70% HRmax.

Sensory tests showed a preference for the sports drink flavor (7.49±1.1 vs. water (5.41±1.5 (p<0.0005. Conclusions: Sports drink enhances voluntary fluid intake more than when only water is available. Ad libitum drinking was greater when a sports drink was available. Sensory scores obtained support this preference for a sports drink vs. water.

    The combination of alcohol with an energy drink (ED) is believed to contribute to risky alcohol-drinking behaviors, such as binge drinking. However, the long-term effects on cognition and reward function that are caused by the repeated binge-like ingestion of alcohol and EDs are still poorly known. The present study examined the effects of a history of repeated exposure to alcohol and/or an ED on short-term memory and alcohol-seeking behavior. Male Wistar rats were given daily intragastric administration of alcohol (3.4g/kg) combined or not with an ED (10.71ml/kg) for 6 consecutive days. The rats were tested for locomotion 15min after the first intragastric treatment. Short-term memory was assessed in the novel object recognition and social discrimination tests 2-3days after the last intragastric administration. The rewarding effect of alcohol was tested 1-3weeks following the last intragastric administration in a conditioned place preference paradigm. The acute binge-like ingestion of alcohol decreased locomotor activity, whereas the combination of alcohol and an ED increased locomotion in the first minutes of assessment. Alcohol exposure produced cognitive deficits in both the object recognition and social discrimination tests, and adding the ED to the alcohol solution did not modify these effects. The combination of alcohol and the ED increased alcohol-induced conditioned place preference. Thus, a history of binge-like alcohol exposure combined with the ED caused subsequent cognitive deficits and increased alcohol seeking behavior, and such behavioral effects might contribute to the progression to alcohol abuse disorders.

  9. Effects of sex and deletion of neuropeptide Y2 receptors from GABAergic neurons on affective and alcohol drinking behaviors in mice

    Full Text Available A large literature has demonstrated that neuropeptide Y (NPY regulates many emotional and reward-related behaviors via its primary receptors, Y1R and Y2R. Classically, NPY actions at postsynaptic Y1R decrease anxiety, depression, and alcohol drinking, while its actions at presynaptic Y2R produce the opposite behavioral phenotypes. However, emerging evidence suggests that activation of Y2R can also produce anxiolysis in a brain region and neurotransmitter system-dependent fashion. Further, numerous human and rodent studies have reported that females display higher levels of anxiety, depression, and alcohol drinking. In this study, we evaluated sex differences and the role of Y2R on GABAergic transmission in these behaviors using a novel transgenic mouse that lacks Y2R specifically in VGAT-expressing neurons (VGAT-Y2R knockout. First, we confirmed our genetic manipulation by demonstrating that Y2R protein expression was decreased and that a Y2R agonist could not alter GABAergic transmission in the extended amygdala, a limbic brain region critically implicated in the regulation of anxiety and alcohol drinking behaviors, using immunofluorescence and slice electrophysiology. Then, we tested male and female VGAT-Y2R knockout mice on a series of behavioral assays for anxiety, depression, fear, anhedonia, and alcohol drinking. We found that females displayed greater basal anxiety, higher levels of ethanol consumption, and faster fear conditioning than males, and that knockout mice exhibited enhanced depressive-like behavior in the forced swim test. Together, these results confirm previous studies that demonstrate higher expression of negative affective and alcohol drinking behaviors in females than males, and they highlight the importance of Y2R function in GABAergic systems in the expression of depressive-like behavior.

    2011-01-01

    Background Interactive and mobile technologies (i.e., smartphones such as Blackberries, iPhones, and palm-top computers) show promise as an efficacious and cost-effective means of communicating health-behavior risks, improving public health outcomes, and accelerating behavior change (Abroms and Maibach, 2008). The present study was conducted as a “needs assessment” to examine the current available mobile smartphone applications (e.g., apps) that utilize principles of ecological momentary assessment (EMA) -- daily self-monitoring or near real-time self-assessment of alcohol use behavior -- to promote positive behavior change, alcohol harm reduction, psycho-education about alcohol use, or abstinence from alcohol. Methods Data were collected and analyzed from iTunes for Apple iPhone©. An inventory assessed the number of available apps that directly addressed alcohol use and consumption, alcohol treatment, or recovery, and whether these apps incorporated empirically-based components of alcohol treatment. Results Findings showed that few apps addressed alcohol use behavior change or recovery. Aside from tracking drinking consumption, a minority utilized empirically-based components of alcohol treatment. Some apps claimed they could serve as an intervention, however no empirical evidence was provided. Conclusions More studies are needed to examine the efficacy of mobile technology in alcohol intervention studies. The large gap between availability of mobile apps and their use in alcohol treatment programs indicate several important future directions for research. PMID:21689119

    Full Text Available Behavior change communication for improving handwashing with soap can be labor and resource intensive, yet quality results are difficult to achieve. Nudges are environmental cues engaging unconscious decision-making processes to prompt behavior change. In this proof-of-concept study, we developed an inexpensive set of nudges to encourage handwashing with soap after toilet use in two primary schools in rural Bangladesh. We completed direct observation of behaviors at baseline, after providing traditional handwashing infrastructure, and at multiple time periods following targeted handwashing nudges (1 day, 2 weeks, and 6 weeks. No additional handwashing education or motivational messages were completed. Handwashing with soap among school children was low at baseline (4%, increasing to 68% the day after nudges were completed and 74% at both 2 weeks and 6 weeks post intervention. Results indicate that nudge-based interventions have the potential to improve handwashing with soap among school-aged children in Bangladesh and specific areas of further inquiry are discussed.

    It is well known that oxidative damage plays a key role in the development of chronic arsenicosis. There is a complex set of mechanisms of redox cycling in vivo to protect cells from the damage. In this study, we examined the differences in the levels of serum thioredoxin1 (TRX1) among individuals exposed to different levels of arsenic in drinking water and detected early biomarkers of arsenic poisoning before the appearance of skin lesions. A total of 157 subjects from endemic regions of China were selected and divided into arsenicosis group with skin lesions (total intake of arsenic: 8.68–45.71 mg-year) and non-arsenicosis group without skin lesions, which further divided into low (0.00–1.06 mg-year), medium (1.37–3.55 mg-year), and high (4.26–48.13 mg-year) arsenic exposure groups. Concentrations of serum TRX1 were analyzed by an ELISA method. Levels of water arsenic and urinary speciated arsenics, including inorganic arsenic (iAs), monomethylated arsenic (MMA), and dimethylated arsenic (DMA), were determined by hydride generation atomic absorption spectrometry. Our results showed that the levels of serum TRX1 in arsenicosis patients were significantly higher than that of the subjects who were chronically exposed to arsenic, but without skin lesions. A positive correlation was seen between the levels of serum TRX1 and the total water arsenic intake or the levels of urinary arsenic species. The results of this study indicate that arsenic exposure could significantly change the levels of human serum TRX1, which can be detected before arsenic-specific dermatological symptoms occur. This study provides further evidence on revealing the mechanism of arsenic toxicity. -- Highlights: ► Three regions are selected as the areas affected by endemic arsenicosis of China. ► We first examine changes in serum TRX1 among individuals exposed to arsenic. ► A positive correlation was seen between serum TRX1 and total water arsenic intake. ► The same relationship

    This study presents an analysis of climate change impacts on a large river located in Québec (Canada) used as a drinking water source. Combined sewer overflow (CSO) effluents are the primary source of fecal contamination of the river. An analysis of river flowrates was conducted using historical data and predicted flows from a future climate scenario. A spatio-temporal analysis of water quality trends with regard to fecal contamination was performed and the effects of changing flowrates on the dilution of fecal contaminants were analyzed. Along the river, there was a significant spatial trend for increasing fecal pollution downstream of CSO outfalls. Escherichia coli concentrations (upper 95th percentile) increased linearly from 2002 to 2012 at one drinking water treatment plant intake. Two critical periods in the current climate were identified for the drinking water intakes considering both potential contaminant loads and flowrates: local spring snowmelt that precedes river peak flow and extra-tropical storm events that occur during low flows. Regionally, climate change is expected to increase the intensity of the impacts of hydrological conditions on water quality in the studied basin. Based on climate projections, it is expected that spring snowmelt will occur earlier and extreme spring flowrates will increase and low flows will generally decrease. High and low flows are major factors related to the potential degradation of water quality of the river. However, the observed degradation of water quality over the past 10 years suggests that urban development and population growth may have played a greater role than climate. However, climate change impacts will likely be observed over a longer period. Source water protection plans should consider climate change impacts on the dilution of contaminants in addition to local land uses changes in order to maintain or improve water quality.

    2015-01-01

    The relationship between level of childhood abuse (physical and emotional) and sexual risk behavior of sexually transmitted disease (STD) clinic patients in St. Petersburg, Russia was examined through path analyses. Mediating variables investigated were: Alcohol Use Disorder Identification Test (AUDIT), drinking motives (for social interaction, to enhance mood, to facilitate sexual encounters), intimate partner violence (IPV), anxiety, and depression symptoms. Results showed a significant indirect effect of childhood abuse on women’s sexual risk behavior: higher level of childhood abuse was associated with a greater likelihood of IPV, motivations to drink, leading to higher AUDIT scores and correlated to higher likelihood of having multiple, new or casual sexual partner(s). No significant effect was identified in paths to condom use. Among men, childhood abuse had no significant effect on sexual risk behavior. Reduction in alcohol-related sexual risk behavior may be achieved by addressing the effects of childhood abuse among female participants. PMID:25801476

    Full Text Available Emerging adulthood marks a critical developmental juncture during which some individuals disengage from the illegal behavior of their adolescence while others continue to use substances and commit crimes. While risk factors for delinquency during adolescence are well studied, factors that influence persisting or desisting from illegal activities during emerging adulthood have not been fully explored. This mixed methods study utilizes a sample of college students aged 18-25 (N=74 and examines factors differentiating those who abstained from illegal behaviors, desisted from illegal behaviors, and persisted in illegal behaviors. Multinomial logistic regression models indicated peers offending and hours spent studying predicted desisting and peers offending predicted persisting (compared to the abstaining group. Three qualitative themes: family and peer bonds, morals and values, and fear of consequences further explained factors influencing emerging adults’ persisting and desisting choices. Implications for social work practice are explored.

    Full Text Available Drinking water has heterogeneous effects on energy intake (EI, energy expenditure (EE, fat oxidation (FO and weight change in randomized controlled trials (RCTs involving adults and/or children. The aim of this qualitative review of RCTs was to identify conditions associated with negative, null and beneficial effects of drinking water on EI, EE, FO and weight, to generate hypotheses about ways to optimize drinking water interventions for weight management. RCT conditions that are associated with negative or null effects of drinking water on EI, EE and/or FO in the short term are associated with negative or null effects on weight over the longer term. RCT conditions that are associated with lower EI, increased EE and/or increased FO in the short term are associated with less weight gain or greater weight loss over time. Drinking water instead of caloric beverages decreases EI when food intake is ad libitum. Drinking water increases EE in metabolically-inflexible, obese individuals. Drinking water increases FO when blood carbohydrate and/or insulin concentrations are not elevated and when it is consumed instead of caloric beverages or in volumes that alter hydration status. Further research is needed to confirm the observed associations and to determine if/what specific conditions optimize drinking water interventions for weight management.

    To ascertain the quality of drinking water being supplied and maintained at Guwahati, the study was conducted on the status of water supply in city through surveillance of drinking water quality for consecutive 7 days at various treatment stages, distribution network and consumer ends. The performance of five water treatment plants (WTPs), viz. Panbazar WTP, Satpukhuri WTP, Kamakhya WTP, PHED WTP and Hegrabari WTP were assessed for summer, piost-post-monsoon and winter seasons. No significant change in raw water quality was observed on day-to-day basis. Residual chlorine was found in the range of nil to 0.2 mg/L in the treated water. During post-monsoon, winter, and summer seasons the thermotolerent TC and FC counts ranged between Nil to 168 CFU/100 ml and Nil to 84 CFU/100 ml; Nil to 3356 CFU/100 ml and Nil to 152 CFU/100 ml; and Nil to 960 CFU/100 ml and Nil to 108 CFU/100 ml respectively. There was variation in bacterial counts among the different service reservoirs and consumer ends, which may be attributed to the general management practices for maintenance of service reservoirs and the possibility of enroute contamination. Evaluation of the raw water quality indicate that the water is suitable for drinking after conventional treatment followed by disinfection. The finished water quality meets the level of standards described as per Bureau of Indian Standard specifications (BIS:10500 1991) for potability in terms of its physico-chemical characteristics.

    Full Text Available Sonal SinghMarketing and Management Department, Macquarie University, Sydney, New South Wales, AustraliaAbstract: It is widely accepted that many social and health problems have underlying behavioral causes. Because these problems are rooted in human behavior, solutions to deal with them also lie in human behavior. This paper examines ways of integrating customer engagement in social programs to influence and initiate behavior change effectively with a special focus on youth. This work followed a theoretical deduction by use of a literature review. Social marketing places emphasis on behavior change, and one of the key challenges for social marketers is to ensure a perceived value for customers in taking up and maintaining positive behavior. If perceptions, beliefs, attitudes, and values influence behavior, then the central focus should be on the youth. Integrating youth is a prerequisite for effective social marketing programs and ultimately behavioral change. This approach will pave the way for effective brand positioning and brand loyalty in social marketing which has been lacking and requires more attention from researchers and policymakers. This paper outlines theoretical developments in social marketing that will increase the effectiveness of social marketing programs overall. Existing social marketing literature typically focuses on social marketing interventions and behavioral change. This paper uses customer engagement within a social marketing context so that social marketing programs are perceived as brands to which youth can relate.Keywords: social marketing, customer engagement, behavioral influence, change, youth

    This article discusses the beneficial effects of setting goals in health behavior change and maintenance interventions. Goal setting theory predicts that, under certain conditions, setting specific difficult goals leads to higher performance when compared with no goals or vague, nonquantitative goals, such as "do your best." In contrast to the graduated, easy goals often set in health behavior change programs, goal setting theory asserts a positive linear relationship between degree of goal difficulty and level of performance. Research on goal setting has typically been conducted in organizational and laboratory settings. Although goal setting procedures are used in many health behavior change programs, they rarely have been the focus of systematic research. Therefore, many research questions still need to be answered regarding goal setting in the context of health behavior change. Finally, initial recommendations for the successful integration of goal setting theory in health behavior change programs are offered.

    Personality traits such as conscientiousness as self-reported by individuals can help predict a range of outcomes, from job performance to longevity. Asking others to rate the personality of their acquaintances often provides even better predictive power than using self-report. Here, we examine whether peer-reported personality can provide a better link between brain function, namely threat-related amygdala activity, and future health-related behavior, namely problem drinking, than self-reported personality. Using data from a sample of 377 young adult university students who were rated on five personality traits by peers, we find that higher threat-related amygdala activity to fearful facial expressions is associated with higher peer-reported, but not self-reported, conscientiousness. Moreover, higher peer-reported, but not self-reported, conscientiousness predicts lower future problem drinking more than one year later, an effect specific to men. Remarkably, relatively higher amygdala activity has an indirect effect on future drinking behavior in men, linked by peer-reported conscientiousness to lower future problem drinking. Our results provide initial evidence that the perceived conscientiousness of an individual by their peers uniquely reflects variability in a core neural mechanism supporting threat responsiveness. These novel patterns further suggest that incorporating peer-reported measures of personality into individual differences research can reveal novel predictive pathways of risk and protection for problem behaviors.

  14. Using goal setting as a strategy for dietary behavior change.

    Cullen, K W; Baranowski, T; Smith, S P

    2001-05-01

    Recent reviews have noted that behavioral theory-based nutrition education programs are more successful at achieving food behavior change than knowledge-based programs and that a clear understanding of the mechanisms of behavior change procedures enable dietetics professionals to more effectively promote change. Successful dietary behavior change programs target 1 or more of the personal, behavioral, or environmental factors that influence the behavior of interest and apply theory-based strategies to influence or change those factors. Goal setting is a strategy that is frequently used to help people change. A 4-step goal-setting process has been identified: recognizing a need for change; establishing a goal; adopting a goal-directed activity and self-monitoring it; and self-rewarding goal attainment. The applications of goal setting in dietary interventions for adults and children are reviewed here. Because interventions using goal setting appear to promote dietary change, dietitians should consider incorporating the goal-setting strategies to enhance the behavior change process in nutrition education programs.

    Adolescence is a time that can set the course of alcohol abuse later in life. Sensitivity to reward on multiple levels is a major factor in this development. We examined 736 adolescents from the IMAGEN longitudinal study for alcohol drinking during early (mean age=14.37) and again later (mean age=16.45) adolescence. Conducting structural equation modeling we evaluated the contribution of reward-related personality traits, behavior, brain responses and candidate genes. Personality seems to be most important in explaining alcohol drinking in early adolescence. However, genetic variations in ANKK1 (rs1800497) and HOMER1 (rs7713917) play an equal role in predicting alcohol drinking two years later and are most important in predicting the increase in alcohol consumption. We hypothesize that the initiation of alcohol use may be driven more strongly by personality while the transition to increased alcohol use is more genetically influenced.

    Full Text Available 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.

    This study examined underage drinkers' responses to negative-restrictive versus proactive-nonrestrictive slogans in humorous anti-alcohol abuse advertisements. The authors conducted a posttest-only control group experiment with 91 teenagers and college-aged participants. For underage moderate drinkers, the negative-restrictive slogans (e.g., "Don't drink") increased participants' perceived risk of excessive drinking and increased a level of intention to change their drinking behavior. However, for underage binge drinkers, the negative-restrictive slogans lowered participants' risk perception of excessive drinking and intention to change their drinking behavior.

    Group housing provides increased access to space and social interactions for calves while reducing labor costs for producers. However, group housing necessarily requires that calves be mixed and no research to date has addressed the effects of mixing on behavior of milk-fed dairy calves. The objective of this study was to monitor the feeding and competitive behavior of individual dairy calves (n = 8) after introduction into an established group of older calves fed ad libitum by a computer-controlled milk feeder. Milk feeding was monitored for 2 d before introduction into the new group and both milk feeding and competitive behaviors were monitored for 4 d after mixing. Mean (+/- SE) milk consumption before mixing was 9.7 +/- 0.7 kg/d, dropped slightly on the day of mixing to 8.6 +/- 0.6 kg/d, but increased on d 1 to 3 after mixing to 11.1 +/- 0.3 kg/d. Calves visited the feeder less frequently on the day of mixing (6.0 +/- 1.8 visits/d) than on either the days before mixing (20.3 +/- 2.5 visits/d) or the days after mixing (25.3 +/- 6.9 visits/ d). The mean duration of feeder visits and mean milk consumption per visit increased from 4 min 15 s +/- 21 s and 0.53 +/- 0.06 kg per visit before mixing to 8 min 17 s +/- 1 min 28 s and 1.87 +/- 0.51 kg per visit on the day of mixing. Competitive displacements from the milk-feeding stall were rare. In summary, feeding behavior of young calves is altered on the day of mixing, but calves are able to maintain milk intake when using a milk feeder fitted with a stall that prevents calves from displacing one another.

Methods 450 college students were investigated with Alcohol Drinking Scale (ADS) and UCLA Loneliness Scale-3rd edition.Results The loneliness and drinking pattern of college students showed significant differences in gender, grade, family economic status, being only-child or not (P <0. 05 or P <0. 01). There was significant positive correlation between loneliness and drinking behavior in college students (r =0. 44,P <0.01). Regression analysis found that the loneliness played a significant role in predicting the drinking behavior in college students (F =60. 073 ,P <0.001). Conclusion The loneliness can predict the drinking behavior in college students. So, the drinking behavior can be reduced by improving their feeling of loneliness.

  6. Influencing behavioral change by customer engagement amongst youth.

    2011-01-01

    It is widely accepted that many social and health problems have underlying behavioral causes. Because these problems are rooted in human behavior, solutions to deal with them also lie in human behavior. This paper examines ways of integrating customer engagement in social programs to influence and initiate behavior change effectively with a special focus on youth. This work followed a theoretical deduction by use of a literature review. Social marketing places emphasis on behavior change, and one of the key challenges for social marketers is to ensure a perceived value for customers in taking up and maintaining positive behavior. If perceptions, beliefs, attitudes, and values influence behavior, then the central focus should be on the youth. Integrating youth is a prerequisite for effective social marketing programs and ultimately behavioral change. This approach will pave the way for effective brand positioning and brand loyalty in social marketing which has been lacking and requires more attention from researchers and policymakers. This paper outlines theoretical developments in social marketing that will increase the effectiveness of social marketing programs overall. Existing social marketing literature typically focuses on social marketing interventions and behavioral change. This paper uses customer engagement within a social marketing context so that social marketing programs are perceived as brands to which youth can relate.

    By analyzing a huge amount of point-of-sale data collected from Japanese supermarkets, we find power law relationships between price and sales numbers. The estimated values of the exponents of these power laws depend on the category of products; however, they are independent of the stores, thereby implying the existence of universal human purchase behavior. The rate of sales numbers around these power laws are generally approximated by log-normal distributions implying that there are hidden random parameters, which might proportionally affect the purchase activity.

    Overweight and obesity are known risk factors for several modifiable, if not preventable diseases. Growing evidence suggests that lesbians may have higher rates of obesity than other women. This study was designed to describe weight loss and behavior changes related to food choices and exercise habits among lesbians who participated in a predominantly lesbian, mainstream, commercial weight loss program. Behavioral changes were recorded in exercise, quality of food choices, and number of times dining out. Although there were several limitations based on sample size and heterogeneity, the impact of a lesbian-supportive environment for behavior change was upheld.

    When has the world changed enough to warrant a new approach? The answer depends on current needs, behavioral flexibility and prior knowledge about the environment. Formal approaches solve the problem by integrating the recent history of rewards, errors, uncertainty and context via Bayesian inference to detect changes in the world and alter behavioral policy. Neuronal activity in posterior cingulate cortex - a key node in the default network - is known to vary with learning, memory, reward and task engagement. We propose that these modulations reflect the underlying process of change detection and motivate subsequent shifts in behavior.

  12. Is Binge Drinking Prevalent in Greece after the Emergence of the Economic Crisis? Assessment of This Idea Using the Theory of Planned Behavior

    George Vlontzos

    2017-01-01

    Full Text Available This paper aims to evaluate the impact of the ongoing economic crisis in Greece on alcohol consumption and binge drinking. For this reason, the Theory of Planned Behavior is being applied by using a sample of nearly 900 questionnaires. The questionnaire consists of parts trying to identify the attitude of the interviewees towards alcohol, their subjective norms of social environment, and the perceived behavioral control. This research has been implemented on a national level. The most important finding is the considerable difference in alcohol consumption compared with other countries faced similar negative economic situations. Drinking is considered as a source of pleasure and socializing. The participants’ perception is that family environment and friends are not considering drinking as a non-desirable way of entertainment. As one of the major results of the survey, drinking was found to not be driven by a necessity to overcome problems related to it, which is the main difference with previous studies in others countries, like Argentina, Russia, USA, etc.

    Uncertainty regarding changes in dissolved organic carbon (DOC) quantity and quality has created interest in managing peatlands for their ecosystem services such as drinking water provision. The evidence base for such interventions is, however, sometimes contradictory. We performed a laboratory climate manipulation using a factorial design on two dominant peatland vegetation types (Calluna vulgaris and Sphagnum Spp.) and a peat soil collected from a drinking water catchment in Exmoor National Park, UK. Temperature and rainfall were set to represent baseline and future conditions under the UKCP09 2080s high emissions scenario for July and August. DOC leachate then underwent standard water treatment of coagulation/flocculation before chlorination. C. vulgaris leached more DOC than Sphagnum Spp. (7.17 versus 3.00 mg g(-1)) with higher specific ultraviolet (SUVA) values and a greater sensitivity to climate, leaching more DOC under simulated future conditions. The peat soil leached less DOC (0.37 mg g(-1)) than the vegetation and was less sensitive to climate. Differences in coagulation removal efficiency between the DOC sources appears to be driven by relative solubilisation of protein-like DOC, observed through the fluorescence peak C/T. Post-coagulation only differences between vegetation types were detected for the regulated disinfection by-products (DBPs), suggesting climate change influence at this scale can be removed via coagulation. Our results suggest current biodiversity restoration programmes to encourage Sphagnum Spp. will result in lower DOC concentrations and SUVA values, particularly with warmer and drier summers.

    In Japan, customers' concerns about chlorinous odour in drinking water have been increasing. One promising approach for reducing chlorinous odour is the minimization of residual chlorine in water distribution, which requires stricter control of organics to maintain biological stability in water supply systems. In this investigation, the levels and seasonal changes of assimilable organic carbon (AOC) and its precursors in drinking water were surveyed to accumulate information on organics in terms of biological stability. In tap water samples purified through rapid sand filtration processes, the average AOC concentration was 174 microgC/L in winter and 60 microgC/L in summer. This difference seemed to reflect the seasonal changes of AOC in the natural aquatic environment. On the other hand, very little or no AOC could be removed after use of an ozonation-biological activated carbon (BAC) process. Especially in winter, waterworks should pay attention to BAC operating conditions to improve AOC removal. The storage of BAC effluent with residual chlorine at 0.05-0.15 mgCl2/L increased AOC drastically. This result indicated the possibility that abundant AOC precursors remaining in the finished water could contribute to newly AOC formation during water distribution with minimized residual chlorine. Combined amino acids, which remained at roughly equivalent to AOC in finished water, were identified as major AOC precursors. Prior to minimization of residual chlorine, enhancement of the removal abilities for both AOC and its precursors would be necessary.

Normally-hydrated quails that received injections of L-HTP (12.5; 25 and 50 mg.kg-1 by the intracoelomic route (ic expressed an increase in water intake, which was inhibited by captopril, an angiotensin converting enzyme (ACE inhibitor. In addition, captopril also induced such a response in birds under previous fluid deprivation. High doses of captopril (35-70 mg.kg-1, sc in normally-hydrated quails decreased the spontaneous water intake while low doses of captopril (2-5 mg.kg-1, sc did not prompt water intake after L-HTP administration. Losartan, an AT1 receptor antagonist in mammals, did not change the water intake levels in normally-hydrated or water-deprivated birds. Serotonin (5-HT injections did not provoke its known dipsogenic response.

    A lot of epidemiological survey on the kinds of risk factors caused by the high incidence of Hepatocellular carcinoma (HCC) in Fusui county,P. R. Of China has been done,especially on relation ship between the different types of drinking water and the mortality of HCC. But the mechanism is no clear. In our study,we sampled the common type of drinking water (pond water,shallow well water,tap water) in Fusui county and did series of cytogenetic determinations such as Chromosomal aberration (CA),Micronuclei (MN) and Sister chromatid exchange (SCE). The changes of CA,MN and SCE related to types of drinking water were observed. There were linear correlation between the concentration of water sample and these changes. The results suggests that one of the reason for the high incidence of HCC in Fusui county may be the presence of mutagen and/or carcinogen existed in the drinking water. The dissimilarity of the different types of drinking water is due to different concentrations of mutagens and/or carcinogens. In brief, the results confirmed the theory of type of drinking water corresponding to incidence rate of HCC proposed by Delong Su on cytogenetics

    Full Text Available Traumatic experiences – such as combat, living in a conflict country or war-torn nation, or experience a violent crimes or natural disasters – change social relationships and may also influence a life-time of consumer relationships with brands and shopping. Our focus on this previously overlooked area is centered on an analysis of the long-term shopping habits 355 combat veterans. We show that those who experienced heavy trauma (e.g., heavy combat exhibited similar disconnection from brands as others have experienced in social relationships. They became more transactional in that they were more open to switching brands, to trying new products, and buying the least expensive alternative (p<0.01. In contrast, those who had experienced a light trauma were more influenced by ads and more open to buying brands even when they cost more (p<0.00. Trauma, such as combat, may change one’s decision horizon. Functionality and price become more important, which is consistent with the idea that they are more focused on the present moment than on building on the past or saving for the future.

    This is the first study to systematically investigate the different behaviors of Microcystis aeruginosa in the sludges formed by AlCl3, FeCl3, and polymeric aluminium ferric chloride (PAFC) coagulants during storage. Results show that the viability of Microcystis aeruginosa in PAFC sludge was stronger than that of cells in either AlCl3 or FeCl3 sludge after the same storage time, while the cells’ viability in the latter two systems stayed at almost the same level. In AlCl3 and FeCl3 sludges high concentrations of Al and Fe were toxic to Microcystis aeruginosa, whereas in PAFC sludge low levels of Al showed little toxic effect on Microcystis aeruginosa growth and moderate amounts of Fe were beneficial to growth. The lysis of Microcystis aeruginosa in AlCl3 sludge was more serious than that in PAFC sludge, for the same storage time. Although the cell viability in FeCl3 sludge was low (similar to AlCl3 sludge), the Microcystis aeruginosa cells remained basically intact after 10 d storage (similar to PAFC sludge). The maintenance of cellular integrity in FeCl3 sludge might be due to the large floc size and high density, which had a protective effect for Microcystis aeruginosa. PMID:27713525

    2016-11-01

    Health-related behaviors such as tobacco, alcohol and other substance use, poor diet and physical inactivity, and risky sexual practices are important targets for research and intervention. Health-related behaviors are especially pertinent targets in the United States, which lags behind most other developed nations on common markers of population health. In this essay we examine the application of behavioral economics, a scientific discipline that represents the intersection of economics and psychology, to the study and promotion of health-related behavior change. More specifically, we review what we consider to be some core dimensions of this discipline when applied to the study health-related behavior change. Behavioral economics (1) provides novel conceptual systems to inform scientific understanding of health behaviors, (2) translates scientific understanding into practical and effective behavior-change interventions, (3) leverages varied aspects of behavior change beyond increases or decreases in frequency, (4) recognizes and exploits trans-disease processes and interventions, and (5) leverages technology in efforts to maximize efficacy, cost effectiveness, and reach. These dimensions are overviewed and their implications for the future of the field discussed.

Repeated exposure to WAS for 7 days had little influence on behavior but prevented the DSS-induced behavioral disturbances in the open field and social interaction tests. In contrast, repeated WAS did not modify colon length, colonic myeloperoxidase content and circulating proinflammatory cytokines, parameters used to assess colitis severity. DSS-induced colitis was associated with an increase in circulating neuropeptide Y (NPY, a rise in the hypothalamic expression of cyclooxygenase-2 mRNA and a decrease in the hippocampal expression of NPY mRNA, brain-derived neurotrophic factor mRNA and mineralocorticoid receptor mRNA. Repeated WAS significantly decreased the relative expression of corticotropin-releasing factor mRNA in the hippocampus. The effect of repeated WAS to blunt the DSS-evoked behavioral disturbances was associated with a rise of circulating corticosterone and an increase in the expression of hypothalamic NPY mRNA. These results show that experimental colitis leads to a particular range of behavioral alterations which can be prevented by repeated WAS, a model of predictable chronic stress, while the severity of colitis remains unabated. We conclude that the mechanisms underlying the resilience effect of repeated WAS involves hypothalamic NPY and the hypothalamic-pituitary-adrenal axis.

    Organizational change is a particularly emotional event for those being confronted with it. Anger is a frequently experienced emotion under these conditions. This study analyses the influence of employees' habitual anger reactions on their reported behavior during organizational change. It was explored whether anger reactions conducive to recovering or increasing individual well-being will enhance the likelihood of functional change behavior. Dysfunctional regulation strategies in terms of individual well-being are expected to decrease the likelihood of functional change behavior-mediated by the commitment to change. Four hundred and twelve employees of different organizations in Luxembourg undergoing organizational change participated in the study. Findings indicate that the anger regulation strategy venting, and humor increase the likelihood of deviant resistance to change. Downplaying the incident's negative impact and feedback increase the likelihood of active support for change. The mediating effect of commitment to change has been found for humor and submission. The empirical findings suggest that a differentiated conceptualization of resistance to change is required. Specific implications for practical change management and for future research are discussed.

    This review summarizes evidence on negative affect among drinking drivers. Elevations in negative affect, including depressed mood, anxiety and hostility, have long been noted in convicted drinking drivers, and recent evidence suggests an association between negative affect and driving after drinking in the general population. Previous efforts to understand the significance of this negative affective state have ranged from suggestions that it may play a causal role in drinking driving to suggestions that it may interfere with response to treatment and remedial interventions. Recent studies have uncovered an important paradox involving negative affect among convicted drinking drivers (hereafter DUI offenders). DUI offenders with high levels of negative affect recidivated more frequently following a DUI program than did those reporting no or minimal negative affect. However, when a brief supportive motivational intervention was added to the program, offenders with high negative affect levels showed lower recidivism rates than did those with no or minimal negative affect. The review includes studies from the general literature on alcohol treatment in which the same negative affect paradox was reported. In an attempt to understand this paradox, we present a conceptual model involving well-established psychological processes, with a focus on salient discrepancy, the crucial component of cognitive dissonance. In this model, negative affect plays an important role in motivating both continued high-risk drinking as well as therapeutic change. This model suggests that links between motivational states and negative affective processes may be more complex than previously thought. Implications for intervention with DUI offenders are discussed.

  13. A Change Impact Analysis to Characterize Evolving Program Behaviors

    2012-01-01

    Change impact analysis techniques estimate the potential effects of changes made to software. Directed Incremental Symbolic Execution (DiSE) is an intraprocedural technique for characterizing the impact of software changes on program behaviors. DiSE first estimates the impact of the changes on the source code using program slicing techniques, and then uses the impact sets to guide symbolic execution to generate path conditions that characterize impacted program behaviors. DiSE, however, cannot reason about the flow of impact between methods and will fail to generate path conditions for certain impacted program behaviors. In this work, we present iDiSE, an extension to DiSE that performs an interprocedural analysis. iDiSE combines static and dynamic calling context information to efficiently generate impacted program behaviors across calling contexts. Information about impacted program behaviors is useful for testing, verification, and debugging of evolving programs. We present a case-study of our implementation of the iDiSE algorithm to demonstrate its efficiency at computing impacted program behaviors. Traditional notions of coverage are insufficient for characterizing the testing efforts used to validate evolving program behaviors because they do not take into account the impact of changes to the code. In this work we present novel definitions of impacted coverage metrics that are useful for evaluating the testing effort required to test evolving programs. We then describe how the notions of impacted coverage can be used to configure techniques such as DiSE and iDiSE in order to support regression testing related tasks. We also discuss how DiSE and iDiSE can be configured for debugging finding the root cause of errors introduced by changes made to the code. In our empirical evaluation we demonstrate that the configurations of DiSE and iDiSE can be used to support various software maintenance tasks

    1987-08-01

    Using a method of monitoring information acquisition, 76 subjects were instructed to simulate the information search process in which they selected a behavior from available behavioral alternatives which were expected to occur in a situation where donating behavior was needed. In order to measure the cognitive changes, they were asked to rate the importance of behavioral attributes both before and after the decision task. After the decision task, they were asked to rate the inner states. (1) Defensive cognitive changes were found which increased the importance of behavioral costs and decreased the importance of personal moral obligation feelings. This pattern of changes was consistent with the Schwartz & Howard model (1981, 1982, 1984). (2) The defensive cognitive changes were related to the information search strategies. This pattern of relationship partly confirmed the prediction derived from the Schwartz & Howard model (1981, 1982, 1984). (3) The result that the cognitive changes were not related to the inner states was inconsistent with the model of either Piliavin, Dovidio, Gaertner, & Clark (1981, 1982) or Schwartz & Howard (1981, 1982, 1984). An alternative model was proposed and discussed.

    This study examined the effectiveness of a traditional face-to-face health education and e-mail health education on alcohol usage among male workers in comparison with a control group. Male workers at a manufacturing plant (N=36) who had abnormal serum gamma-GTP were stratified by age and job types, then randomized into three groups: face-to-face education, e-mail education, and the control. The subjects were assessed on their knowledge about and attitude towards drinking, reported alcohol consumption, and serum gamma-GTP before the start of education and 2 months later after comparison of the education. Paired t-test and repeated ANOVA were conducted to test the significance of changes pre and post the intervention and across groups. In the face-to-face group, knowledge (p=0.001), attitude (p=0.026), alcohol consumption (p=0.003) and serum gamma-GTP showed significant improvement. In the e-mail group, only alcohol consumption showed marginal improvement (p=0.077). In the control group, no variables remarkably changed. These results indicate that the face-to-face health education was more effective than the e-mail program. We discuss why the face-to-face approach was superior to the e-mail approach in this study by referring to self-monitoring, goal setting processes and timely feedback. We concluded that further studies are warranted to identify the effect of health education using e-mails and other network tools in consideration of the above three factors.

    2017-01-01

    The ability to regulate and subsequently change behavior is influenced by both reflective and implicit processes. Traditional theories have focused on conscious processes by highlighting the beliefs and intentions that influence decision making. However, their success in changing behavior has been modest with a gap between intention and behavior apparent. Dual-process models have been recently applied to health psychology; with numerous models incorporating implicit processes that influence behavior as well as the more common conscious processes. Such implicit processes are theorized to govern behavior non-consciously. The article provides a commentary on motivational and volitional processes and how interventions have combined to attempt an increase in positive health behaviors. Following this, non-conscious processes are discussed in terms of their theoretical underpinning. The article will then highlight how these processes have been measured and will then discuss the different ways that the non-conscious and conscious may interact. The development of interventions manipulating both processes may well prove crucial in successfully altering behavior.

    Behavior change theories and models, validated within the field of dietetics, offer systematic explanations for nutrition-related behavior change. They are integral to the nutrition care process, guiding nutrition assessment, intervention, and outcome evaluation. The American Dietetic Association Evidence Analysis Library Nutrition Counseling Workgroup conducted a systematic review of peer-reviewed literature related to behavior change theories and strategies used in nutrition counseling. Two hundred fourteen articles were reviewed between July 2007 and March 2008, and 87 studies met the inclusion criteria. The workgroup systematically evaluated these articles and formulated conclusion statements and grades based upon the available evidence. Strong evidence exists to support the use of a combination of behavioral theory and cognitive behavioral theory, the foundation for cognitive behavioral therapy (CBT), in facilitating modification of targeted dietary habits, weight, and cardiovascular and diabetes risk factors. Evidence is particularly strong in patients with type 2 diabetes receiving intensive, intermediate-duration (6 to 12 months) CBT, and long-term (>12 months duration) CBT targeting prevention or delay in onset of type 2 diabetes and hypertension. Few studies have assessed the application of the transtheoretical model on nutrition-related behavior change. Little research was available documenting the effectiveness of nutrition counseling utilizing social cognitive theory. Motivational interviewing was shown to be a highly effective counseling strategy, particularly when combined with CBT. Strong evidence substantiates the effectiveness of self-monitoring and meal replacements and/or structured meal plans. Compelling evidence exists to demonstrate that financial reward strategies are not effective. Goal setting, problem solving, and social support are effective strategies, but additional research is needed in more diverse populations. Routine documentation

    This paper examines the stock market behavior for a long-lived subset of firms in Shanghai and Shenzhen CSI 300 Index (CSI 300 Index) both before and after the establishment of firms' Microblogging in Sina Weibo. The empirical results show a significant increase in the relative trading volume as well as the decreases in the daily expected stock return and firm-level volatility in the post-Sina Weibo period. These findings suggest that Sina Weibo as an alternative information interaction channel has changed the information environment for individual stock, enhanced the speed of information diffusion and therefore changed the overall stock market behavior.

    Purpose . The association between short sleep and obesity risk is well established. However, we explore a new pathway between short sleep and obesity: whether short sleep is linked to more time spent in secondary eating or drinking, that is, eating or drinking (beverages other than water, such as sugar-sweetened beverages) while primarily engaged in another activity, such as television watching. Design . This pooled cross-sectional study uses data from the American Time Use Survey (ATUS) from 2006 to 2008. Setting . The study takes place in the United States. Subjects . Subjects are 28,150 adults (55.8% female) aged 21 to 65 who were surveyed in the ATUS. Measures . Outcomes are time spent on (1) secondary eating and drinking and (2) primary eating and drinking. Our main predictor variable is sleep duration. Analysis . Controlling for demographic and socioeconomic characteristics of the respondents, we estimate multivariate regression-analysis models for the full sample, as well as by weekday/weekend status, race, and gender subgroups. Results . In multivariate models, compared to respondents reporting normal sleep, short sleep was associated with additional 8.7 (SE = 2.1) minutes per day of secondary eating (p sleep is associated with more time spent in secondary eating and, in particular, secondary drinking. This potentially suggests a pathway from short sleep to increased caloric intake in the form of beverages and distracted eating and thus potential increased obesity risk, although more research is needed.

    Full Text Available Abstract Background Many studies of adults with acute and chronic solvent exposure have shown adverse effects on cognition, behavior and mood. No prior study has investigated the long-term impact of prenatal and early childhood exposure to the solvent tetrachloroethylene (PCE on the affinity for risky behaviors, defined as smoking, drinking or drug use as a teen or adult. Objectives This retrospective cohort study examined whether early life exposure to PCE-contaminated drinking water influenced the occurrence of cigarette smoking, alcohol consumption, and drug use among adults from Cape Cod, Massachusetts. Methods Eight hundred and thirty-one subjects with prenatal and early childhood PCE exposure and 547 unexposed subjects were studied. Participants completed questionnaires to gather information on risky behaviors as a teenager and young adult, demographic characteristics, other sources of solvent exposure, and residences from birth through 1990. PCE exposure was estimated using the U.S. EPA's water distribution system modeling software (EPANET that was modified to incorporate a leaching and transport model to estimate PCE exposures from pipe linings. Results Individuals who were highly exposed to PCE-contaminated drinking water during gestation and early childhood experienced 50-60% increases in the risk of using two or more major illicit drugs as a teenager or as an adult (Relative Risk (RR for teen use = 1.6, 95% CI: 1.2-2.2; and RR for adult use = 1.5, 95% CI: 1.2-1.9. Specific drugs for which increased risks were observed included crack/cocaine, psychedelics/hallucinogens, club/designer drugs, Ritalin without a prescription, and heroin (RRs:1.4-2.1. Thirty to 60% increases in the risk of certain smoking and drinking behaviors were also seen among highly exposed subjects. Conclusions The results of this study suggest that risky behaviors, particularly drug use, are more frequent among adults with high PCE exposure levels during gestation

    2012-05-03

    Melatonin, an indoleamine hormone synthesized in the pinealocytes, has been implicated as influencing the intake of alcohol in rats. It has been shown that this hormone is voltammetrically electroactive at the surface of pretreated carbon fiber microelectrodes in vitro and in vivo, in rat cerebral melatonergic regions such the pineal gland. The aim of this work consisted in the study of the influence of melatonin on spontaneously ethanol drinking or ethanol avoiding rats selected throughout a free choice two bottle test. It appeared that only the water preferring rats were affected by treatment with the hormone and that in vivo voltammetric related levels of melatonin were higher in the pineal gland of ethanol drinking rats versus water preferring rats. In addition, when treated with the melatonin antagonist GR128107 ethanol drinking rats significantly reduced the spontaneous consumption of alcohol.

    2014-01-01

    This study uses the influence of presumed media influence model as the theoretical framework to examine how perceived social norms (i.e., descriptive, subjective, and injunctive norms) will mediate the influence of pro- and antidrinking media messages on adolescents' intention to consume alcohol in rural Thailand. Data collected from 1,028 high school students indicate that different mechanisms underlie drinking intentions between nondrinkers and those who have consumed alcohol or currently drink. Among nondrinkers, perceived peer attention to prodrinking messages indirectly influenced adolescents' prodrinking attitudes and intentions to consume alcohol through all three types of perceived social norms. Among drinkers, perceived peer attention to pro- and antidrinking messages indirectly influenced adolescents' prodrinking attitudes and intentions to drink alcohol through perceived subjective norm. The findings provide support for the extended influence of presumed media influence model and have practical implications for how antidrinking campaigns targeted at teenagers in Thailand might be designed.

    2012-10-01

    The purpose of this literature review is to describe and assess the cultural barriers to behavior change in migrant South Asians, given the high morbidity and mortality associated with cardiovascular disease in this population. We reviewed studies that explored the relationship between South Asian culture in the Diaspora and lifestyle behaviors. Our review produced 91 studies, of which 25 discussed the relationship between various aspects of South Asians' belief system and their approach to modifying lifestyle habits. We identify 6 specific categories of beliefs which play the largest role in the difficulties South Asians describe with behavior change: gender roles, body image, physical activity misconceptions, cultural priorities, cultural identity, and explanatory model of disease. Future research and interventions should account for these cultural factors to successfully improve dietary habits and physical activity levels in migrant South Asian populations.

    Full Text Available The function of subthalamic nucleus (STN which is a part of the basal ganglia system is not clear, but it is hypothesized that this component might be involved in action selection. Unilateral damage to STN, which can commonly occur due to the small vessel stroke mainly, causes hemiballismus and sometimes hemichorea-hemiballismus. This paper deals with a 60-year-old patient with sudden onset of abnormal movements in his right limbs. He had increased appetite and hyperphagia and also developed mood and behavioral changes (aggressiveness, irritability, anxiety, and sometimes obscene speech. The magnetic resonance imaging revealed infarct area in left subthalamus. In our case, hemiballismus is caused by infarction in left subthalamic area. Occurrence of irritability, anxiety, and some behavioral changes such as aggressiveness and obscene speech can be explained by impairment of STN role in nonmotor behavior and cognitive function as a result of infarct.

    2015-01-01

    Little research has focused on the relationship between religion and climate change attitudes and behavior. Further, while there have been some studies examining the relationship between environmental attitudes and religion, most are focused on Christian denominations and secularism, and few have examined other religions such as Buddhism. Using an online survey of 1,927 Australians we examined links between membership of four religious groupings (Buddhists, Christian literalists and non-literalists, and Secularists) and climate change attitudes and behaviors. Differences were found across religious groups in terms of their belief in: (a) human induced climate change, (b) the level of consensus among scientists, (c) their own efficacy, and (d) the need for policy responses. We show, using ordinal regression, that religion explains these differences even after taking into account socio-demographic factors, knowledge and environmental attitude, including belief in man's dominion over nature. Differences in attitude and behavior between these religious groups suggest the importance of engaging denominations to encourage change in attitudes and behavior among their members.

  2. Camera on Vessel: A Camera-Based System to Measure Change in Water Volume in a Drinking Glass

    Directory of Open Access Journals (Sweden)

    Idowu Ayoola

    2015-09-01

    Full Text Available A major problem related to chronic health is patients’ “compliance” with new lifestyle changes, medical prescriptions, recommendations, or restrictions. Heart-failure and hemodialysis patients are usually placed on fluid restrictions due to their hemodynamic status. A holistic approach to managing fluid imbalance will incorporate the monitoring of salt-water intake, body-fluid retention, and fluid excretion in order to provide effective intervention at an early stage. Such an approach creates a need to develop a smart device that can monitor the drinking activities of the patient. This paper employs an empirical approach to infer the real water level in a conically shapped glass and the volume difference due to changes in water level. The method uses a low-resolution miniaturized camera to obtain images using an Arduino microcontroller. The images are processed in MATLAB. Conventional segmentation techniques (such as a Sobel filter to obtain a binary image are applied to extract the level gradient, and an ellipsoidal fitting helps to estimate the size of the cup. The fitting (using least-squares criterion between derived measurements in pixel and the real measurements shows a low covariance between the estimated measurement and the mean. The correlation between the estimated results to ground truth produced a variation of 3% from the mean.

    This study examined the availability of free drinking water during lunchtime in US public schools, as required by federal legislation beginning in the 2011-2012 school year. Data were collected by mail-back surveys in nationally representative samples of US public elementary, middle, and high schools from 2009-2010 to 2011-2012. Overall, 86.4%, 87.4%, and 89.4% of students attended elementary, middle, and high schools, respectively, that met the drinking water requirement. Most students attended schools with existing cafeteria drinking fountains and about one fourth attended schools with water dispensers. In middle and high schools, respondents were asked to indicate whether drinking fountains were clean, and whether they were aware of any water-quality problems at the school. The vast majority of middle and high school students (92.6% and 90.4%, respectively) attended schools where the respondent perceived drinking fountains to be clean or very clean. Approximately one in four middle and high school students attended a school where the survey respondent indicated that there were water-quality issues affecting drinking fountains. Although most schools have implemented the requirement to provide free drinking water at lunchtime, additional work is needed to promote implementation at all schools. School nutrition staff at the district and school levels can play an important role in ensuring that schools implement the drinking water requirement, as well as promote education and behavior-change strategies to increase student consumption of water at school.

    Extinguished operant behavior can return or “resurge” when a response that has replaced it is also extinguished. Typically studied in nonhuman animals, the resurgence effect may provide insight into relapse that is seen when reinforcement is discontinued following human contingency management (CM) and functional communication training (FCT) treatments, which both involve reinforcing alternative behaviors to reduce behavioral excess. Although the variables that affect resurgence have been studied for some time, the mechanisms through which they promote relapse are still debated. We discuss three explanations of resurgence (response prevention, an extension of behavioral momentum theory, and an account emphasizing context change) as well as studies that evaluate them. Several new findings from our laboratory concerning the effects of different temporal distributions of the reinforcer during response elimination and the effects of manipulating qualitative features of the reinforcer pose a particular challenge to the momentum-based model. Overall, the results are consistent with a contextual account of resurgence, which emphasizes that reinforcers presented during response elimination have a discriminative role controlling behavioral inhibition. Changing the “reinforcer context” at the start of testing produces relapse if the organism has not learned to suppress its responding under conditions similar to the ones that prevail during testing.

    Alcohol use can be understood as a strategic behavior, such that people choose to drink based on the anticipated affective changes produced by drinking relative to those produced by alternative behaviors. This study investigated whether people who report drinking for specific reasons via the Drinking Motives Questionnaire-Revised (DMQ-R; Cooper, 1994) actually experience the alcohol effects they purportedly seek. As a secondary goal, we examined relations between drinking motives and indices of the amount of alcohol consumed. Data were drawn from 3,272 drinking episodes logged by 393 community-recruited drinkers during a 21-day Ecological Momentary Assessment investigation. After accounting for selected covariates, DMQ-R enhancement motives uniquely predicted real-time reports of enhanced drinking pleasure. DMQ-R coping motives were associated with reports of increased drinking-contingent relief and punishment. Enhancement motives uniquely predicted consuming more drinks per episode and higher peak intra-episode estimated blood alcohol concentration. The findings extend the evidence for the validity of the DMQ-R motive scores by demonstrating that internal drinking motives (enhancement and coping) are related to the experienced outcomes of drinking in the manner anticipated by theory.

    Background The transtheoretical model (TTM) has been widely used to promote healthy behaviors in different groups. However, a questionnaire has not yet been developed to evaluate the health behaviors that medical practitioners often consider in individuals with cancer or at a high risk of developing cancer. Purpose The aim of this study was to construct and validate the Health Behavior and Stages of Change Questionnaire (HBSCQ), which is based on the TTM and health recommendations related to risk and factors that protect against cancer. Methods Content validity was conducted in two phases (qualitative and quantitative). Item difficulty index, item discrimination index, and discrimination coefficient were obtained based on the classical test theory. Finally, Cronbach’s alpha was used. Results Measure of concordance showed scores considered adequate and excellent. The item discrimination index obtained a rating of “excellent” and suggested the preservation of all items. The discrimination coefficient scores are >0.74. The global internal consistency of the HBSCQ was 0.384. HBSCQ specification between groups of internal consistency for the sample of men was 0.712 and that for the sample of women was 0.378. Conclusion/implications for practice The HBSCQ represents a proposal for a fast, simple, and innovative screening test, which aims to identify persons who may benefit from interventions to promote health behaviors delimited to the stage of change.

    In the Netherlands, July 1st 2011, the new potable water legislation came into force. This resulted in major changes in Legionella prevention at priority installations. But this is not the only impact on the installation sector and building owners and users. For materials, more stringent requirements came into force, also for the use of grey water. Potable water companies have a legal obligation to deliver a certain amount of water under a certain pressure. [Dutch] Per I juli 2011 is de nieuwe Drinkwaterwetgeving in werking getreden.

    Full Text Available Most hydrological models are valid at most only in a few places and cannot be reasonably transferred to other places or to far distant time periods. Transfer in space is difficult because the models are conditioned on past observations at particular places to define parameter values and unobservable processes that are needed to fully characterize the structure and functioning of the landscape. Transfer in time has to deal with the likely temporal changes to both parameters and processes under future changed conditions. This remains an important obstacle to addressing some of the most urgent prediction questions in hydrology, such as prediction in ungauged basins and prediction under global change. In this paper, we propose a new approach to catchment hydrological modeling, based on universal principles that do not change in time and that remain valid across many places. The key to this framework, which we call behavioral modeling, is to assume that there are universal and time-invariant organizing principles that can be used to identify the most appropriate model structure (including parameter values and responses for a given ecosystem at a given moment in time. These organizing principles may be derived from fundamental physical or biological laws, or from empirical laws that have been demonstrated to be time-invariant and to hold at many places and scales. Much fundamental research remains to be undertaken to help discover these organizing principles on the basis of exploration of observed patterns of landscape structure and hydrological behavior and their interpretation as legacy effects of past co-evolution of climate, soils, topography, vegetation and humans. Our hope is that the new behavioral modeling framework will be a step forward towards a new vision for hydrology where models are capable of more confidently predicting the behavior of catchments beyond what has been observed or experienced before.

  13. Collapsibility and Volume Change Behavior of Unsaturated Residual Soil

    2006-01-01

    Full Text Available Residual soils occur in most countries of the world but the greater areas and depths are normally found in tropical humid areas. In these places, the soil forming processes are still very active and the weathering development is much faster than the erosive factor. Most residual soil exhibit high suctions for most of the year. The absence of positive pore water pressure except immediately after rain, makes conventional soil mechanics for saturated soil not so relevant. Ignorance or lack of understanding of the geotechnical behavior of soil in the partially or unsaturated state has caused a lot of damages to infrastructures, buildings and other structures. For instance, the collapsibility and volume change of partially saturated soils in connection with the drying or wetting causes a lot of damage in foundation, roads and other structures. It is also observed that many shallow slope failures involve a slumping (collapse type of failure. As such, the development of extended soil mechanics, which embraces the soil in the unsaturated state or subjected to soil suction, is essential. This study examines the collapsibility and volume change behavior specifically of an unsaturated residual soil under various levels of applied matric suction (ua-uw and net mean stress (σ-ua in a predetermined stress path. The volume change of the soil is found to be sensitive to both the applied matric suction and net mean stress. The soil is found to exhibit a collapsibility behavior upon a reduction in applied matric suction at constant net mean stress.

    Full Text Available Among the anthropic activities generating potentially toxic residues are those involved with bovine hide processing (tannery industries. However, knowledge is scant regarding the damage caused to the health of various organisms by tannery waste and studies are rare, especially in mammalian experimental models. This study therefore aimed to evaluate the physical and behavioral effects of the exposure of female Swiss mice to tannery effluent. To accomplish this, for a period of 15 days the animals were fed tannery effluent diluted with water in the following concentrations: 0% (control group, received only potable water, 5% and 10%. The body mass of the animals was evaluated at the beginning and end of the experiment, as well as the daily consumption of water and food. After 15 days of exposure to the effluent, the animals were submitted to the elevated plus maze (predictive of anxiety and the forced swim test (predictive of depression. The treatments did not affect the animals' body mass, either in eating behavior or in consumption of water. However, it was found that the animals that ingested tannery effluent concentrations of 5% and 10% exhibited an anxiolytic (lower level of anxiety, greater percentage of time in the open arms, longer time and frequency in the diving behavior, less time of lurks and less frequency of freezing and an antidepressant effect (more time in climbing behavior and less time of immobility when compared to the control group. It was concluded that the exposure of female Swiss mice to tannery effluents (5% and 10% diluted with water causes behavioral changes, possibly related to the neurotoxicity of this waste, without causing physical changes in the animals.

    Full Text Available Abstract Background Previous research has indicated that children's behaviors have long-term effects on later life. Hence it is important to monitor the development of health risk behaviors in childhood. This study examined the changes in health risk behaviors in fourth- to sixth-grade students in northern Taiwan from 2001 to 2003. Methods The Child and Adolescent Behaviors in Long-Term Evolution (CABLE study collected data from 1,820 students from 2001 to 2003 (students were 9 or 10 years old in 2001. Exploratory factor analysis was used to determine the aggregation of health risk behaviors. A linear growth curve model was used to determine whether health risk behaviors changed over time. Results Of the 13 behaviors, staying up late and eating snacks late at night were the most prevalent (82.3% of subjects in 2001, 81.8% in 2002, 88.5% in 2003 and second most prevalent (68.7%, 67.4%, 71.6% behaviors, respectively, from 2001 to 2003. The three least prevalent health risk behaviors were chewing betel nut (1.0%, 0.4%, 0.2%, smoking (1.4%, 1.0%, 0.8%, and drinking alcohol (8.5%, 6.0%, 5.2%. The frequencies of swearing and staying up late showed the greatest significant increases with time. On the other hand, suppressing urination and drinking alcohol decreased over time. Using exploratory factor analysis, we aggregated the health risk behaviors into three categories: unhealthy habits, aggressive behaviors, and substance use. Although students did not display high levels of aggressive behavior or experimentation with substances, the development of these behaviors in a small proportion of students should not be ignored. The results of the linear growth curve model indicated that unhealthy habits and aggressive behaviors increased over time. However, substance use slightly decreased over time. Conclusion We found that some health risk behaviors increased with time while others did not. Unhealthy habits and aggressive behaviors increased, whereas

    Forests form the critical source water areas for downstream drinking water supplies in many parts of the world, including the Rocky Mountain regions of North America. Large scale natural disturbances from wildfire and severe insect infestation are more likely because of warming climate and can significantly impact water quality downstream of forested headwaters regions. To investigate potential implications of changing climate and wildfire on drinking water treatment, the 2003 Lost Creek Wildfire in Alberta, Canada was studied. Four years of comprehensive hydrology and water quality data from seven watersheds were evaluated and synthesized to assess the implications of wildfire and post-fire intervention (salvage-logging) on downstream drinking water treatment. The 95th percentile turbidity and DOC remained low in streams draining unburned watersheds (5.1 NTU, 3.8 mg/L), even during periods of potential treatment challenge (e.g., stormflows, spring freshet); in contrast, they were elevated in streams draining burned (15.3 NTU, 4.6 mg/L) and salvage-logged (18.8 NTU, 9.9 mg/L) watersheds. Persistent increases in these parameters and observed increases in other contaminants such as nutrients, heavy metals, and chlorophyll-a in discharge from burned and salvage-logged watersheds present important economic and operational challenges for water treatment; most notably, a potential increased dependence on solids and DOC removal processes. Many traditional source water protection strategies would fail to adequately identify and evaluate many of the significant wildfire- and post-fire management-associated implications to drinking water "treatability"; accordingly, it is proposed that "source water supply and protection strategies" should be developed to consider a suppliers' ability to provide adequate quantities of potable water to meet demand by addressing all aspects of drinking water "supply" (i.e., quantity, timing of availability, and quality) and their relationship

    Background. Ibuprofen is used chronically in different animal models of inflammation by administration in drinking water or in diet due to its short half-life. Though this practice has been used for years, ibuprofen doses were never assayed against parenteral dose-response curves. This study aims at identifying the equivalent intraperitoneal (i.p.) doses of ibuprofen, when it is administered in drinking water or in diet. Methods. Bioassays were performed using formalin test and incisional pain model for antinociceptive efficacy and serum TXB2 for eicosanoid inhibitory activity. The dose-response curve of i.p. administered ibuprofen was constructed for each test using 50, 75, 100 and 200 mg/kg body weight (b.w.). The dose-response curves were constructed of phase 2a of the formalin test (the most sensitive phase to COX inhibitory agents), the area under the 'change in mechanical threshold'-time curve in the incisional pain model and serum TXB2 levels. The assayed ibuprofen concentrations administered in drinking water were 0.2, 0.35, 0.6 mg/ml and those administered in diet were 82, 263, 375 mg/kg diet. Results. The 3 concentrations applied in drinking water lay between 73.6 and 85.5 mg/kg b.w., i.p., in case of the formalin test; between 58.9 and 77.8 mg/kg b.w., i.p., in case of the incisional pain model; and between 71.8 and 125.8 mg/kg b.w., i.p., in case of serum TXB2 levels. The 3 concentrations administered in diet lay between 67.6 and 83.8 mg/kg b.w., i.p., in case of the formalin test; between 52.7 and 68.6 mg/kg b.w., i.p., in case of the incisional pain model; and between 63.6 and 92.5 mg/kg b.w., i.p., in case of serum TXB2 levels. Discussion. The increment in pharmacological effects of different doses of continuously administered ibuprofen in drinking water or diet do not parallel those of i.p. administered ibuprofen. It is therefore difficult to assume the equivalent parenteral daily doses based on mathematical calculations.

    Full Text Available BACKGROUND Based on aggregate statistics, the population of Israel, as compared to all or most other developed societies, has very high levels of fertility and marriage (e.g. TFR of 2.96 in 2009 and only 9.7Š never married among women aged 40-44 in 2009. However, studying aggregate demographic measures is problematic, because Israel is an extremely heterogeneous society, with family formation patterns differing greatly across numerically important social groups. Until now, little has been documented about the basic fertility and marriage behavior of different population groups. OBJECTIVE We describe the fertility and marriage behavior of populations in Israel, broken down by nationality, religion, religiosity and nativity-status. Although our main focus is on a detailed presentation of fertility patterns, we also look at marriage behavior, as it is closely related to fertility in Israel. METHODS We analyze recently available annual data from the Israel Social Surveys for 2002-2009, which, for the first time in several decades,, provides detailed information on family and household demographic behavior and direct information on level of religiosity. We focus primarily on comparisons across cohorts born from the late 1940s to the late 1960s and between periods in the early and late 2000s. RESULTS We provide a detailed portrait of striking diversity in fertility and marriage behavior across population groups, along with important patterns of change and stability across cohorts and over time. We document findings and differential patterns, some unexpected, regarding comparisons across groups and across cohorts. CONCLUSIONS The descriptive findings form the basis for a clearer understanding of fertility and marriage patterns in different population subgroups in Israel. In addition, the reported results suggest many questions for future research, which are outlined in the paper.

    This paper is one in a series developed through a process of expert consensus to provide an overview of questions of current importance in research into engagement with digital behavior change interventions, identifying guidance based on research to date and priority topics for future research. The first part of this paper critically reflects on current approaches to conceptualizing and measuring engagement. Next, issues relevant to promoting effective engagement are discussed, including how best to tailor to individual needs and combine digital and human support. A key conclusion with regard to conceptualizing engagement is that it is important to understand the relationship between engagement with the digital intervention and the desired behavior change. This paper argues that it may be more valuable to establish and promote "effective engagement," rather than simply more engagement, with "effective engagement" defined empirically as sufficient engagement with the intervention to achieve intended outcomes. Appraisal of the value and limitations of methods of assessing different aspects of engagement highlights the need to identify valid and efficient combinations of measures to develop and test multidimensional models of engagement. The final section of the paper reflects on how interventions can be designed to fit the user and their specific needs and context. Despite many unresolved questions posed by novel and rapidly changing technologies, there is widespread consensus that successful intervention design demands a user-centered and iterative approach to development, using mixed methods and in-depth qualitative research to progressively refine the intervention to meet user requirements.

    Alcohol policies have potentially far-reaching impacts on risky sexual behavior, prenatal health behaviors, and subsequent outcomes for infants. After finding initial evidence in the National Longitudinal Survey of Youth (NLSY) that changes in the minimum legal drinking age (MLDA) are related to prenatal drinking, we examine whether the drinking age influences birth outcomes. Using data from the National Vital Statistics (NVS) for the years 1978-1988, we find that a drinking age of 18 is associated with adverse outcomes among births to young mothers-including higher incidences of low birth weight and premature birth, but not congenital anomalies. The effects are largest among black women. We also report evidence that the MLDA laws alter the composition of births that occur. In states with lenient drinking laws, young black mothers are less likely to report paternal information on the birth certificate, particularly in states with restrictive abortion policies. The evidence suggests that lenient drinking laws generate poor birth outcomes in part because they increase the number of unplanned pregnancies.

    Social norms affect human behavior, and underage drinking is no exception. Using the theory of normative social behavior, this study tested the proposition that the association between perceptions about the prevalence of drinking (descriptive norms) and underage drinking is strengthened when perceived pressures to conform (injunctive norms) and beliefs about the benefits of drinking (outcome expectations) are high. This proposition was tested on a nationally representative sample of underage drinkers ages 13-20 (N = 1,031) in relation to their alcohol consumption, expanding on research with college-age youth. On average, males and females reported drinking 23 and 18 drinks per month, respectively. The main effect of descriptive norms (β = .10, p Underage drinkers are most vulnerable to excessive drinking if they believe that most others drink, that they themselves are expected to drink, and that drinking confers several benefits. Norms-based interventions to reduce youth alcohol use need to focus on changing not only descriptive norms but also injunctive norms and outcome expectations.

    Full Text Available BACKGROUND: There are lingering concerns about caffeine consumption during pregnancy or the early postnatal period, partly because there may be long-lasting behavioral changes after caffeine exposure early in life. METHODOLOGY/PRINCIPAL FINDINGS: We show that pregnant wild type (WT mice given modest doses of caffeine (0.3 g/l in drinking water gave birth to offspring that as adults exhibited increased locomotor activity in an open field. The offspring also responded to cocaine challenge with greater locomotor activity than mice not perinatally exposed to caffeine. We performed the same behavioral experiments on mice heterozygous for adenosine A(1 receptor gene (A(1RHz. In these mice signaling via adenosine A(1 receptors is reduced to about the same degree as after modest consumption of caffeine. A(1RHz mice had a behavioral profile similar to WT mice perinatally exposed to caffeine. Furthermore, it appeared that the mother's genotype, not offspring's, was critical for behavioral changes in adult offspring. Thus, if the mother partially lacked A(1 receptors the offspring displayed more hyperactivity and responded more strongly to cocaine stimulation as adults than did mice of a WT mother, regardless of their genotype. This indicates that long-term behavioral alterations in the offspring result from the maternal effect of caffeine, and not a direct effect on fetus. WT offspring from WT mother but having a A(1R Hz grandmother preserved higher locomotor response to cocaine. CONCLUSIONS/SIGNIFICANCE: We suggest that perinatal caffeine, by acting on adenosine A(1 receptors in the mother, causes long-lasting behavioral changes in the offspring that even manifest themselves in the second generation.

    Evidence based practice demonstrates using clippers immediately before surgery, when perioperative hair removal is necessary, results in the fewest surgical site infections (Kjonniksen, Andersen, Sondenaa, & Segadal, 2002). In addition, one of The Joint Commission's national patient safety goals for 2008 is "to reduce the risk of healthcare associated infections" (The Joint Commission, 2008, Goal 7). Therefore, a project was undertaken to change perioperative nursing care in a large teaching hospital from using razors for hair removal in the perioperative setting to using clippers. Change is difficult and encompasses many interdisciplinary areas. A description of the process of utilizing evidence to change behavior in the perioperative setting and its outcomes will be provided in this paper. Klevens, et al., (2007) reported that 22% of healthcare associated infections were the result of surgical site infections (SSIs). Changing practice to utilizing clippers for hair removal is an extrinsic factor of SSIs that can be easily modified. Otorhinolaryngology (ORL) patients that require hair removal before surgery (i.e., acoustic neuroma, cranial-facial resections, and head and neck reconstruction) may benefit from this change in practice. Perioperative nurses are in a prime position to reduce the incidence of SSIs in ORL patients.

  11. Characterizing Behavioral and Brain Changes Associated with Practicing Reasoning Skills.

    Full Text Available We have reported previously that intensive preparation for a standardized test that taxes reasoning leads to changes in structural and functional connectivity within the frontoparietal network. Here, we investigated whether reasoning instruction transfers to improvement on unpracticed tests of reasoning, and whether these improvements are associated with changes in neural recruitment during reasoning task performance. We found behavioral evidence for transfer to a transitive inference task, but no evidence for transfer to a rule generation task. Across both tasks, we observed reduced lateral prefrontal activation in the trained group relative to the control group, consistent with other studies of practice-related changes in brain activation. In the transitive inference task, we observed enhanced suppression of task-negative, or default-mode, regions, consistent with work suggesting that better cognitive skills are associated with more efficient switching between networks. In the rule generation task, we found a pattern consistent with a training-related shift in the balance between phonological and visuospatial processing. Broadly, we discuss general methodological considerations related to the analysis and interpretation of training-related changes in brain activation. In summary, we present preliminary evidence for changes in brain activation associated with practice of high-level cognitive skills.

    High-throughput and deep DNA sequencing, particularly amplicon sequencing, is being increasingly utilized to reveal spatial and temporal dynamics of bacterial communities in drinking water systems. Whilst the sampling and methodological biases associated with PCR and sequencing have been studied in other environments, they have not been quantified for drinking water. These biases are likely to have the greatest effect on the ability to characterize subtle spatio-temporal patterns influenced by process/environmental conditions. In such cases, intra-sample variability may swamp any underlying small, systematic variation. To evaluate this, we undertook a study with replication at multiple levels including sampling sites, sample collection, PCR amplification, and high throughput sequencing of 16S rRNA amplicons. The variability inherent to the PCR amplification and sequencing steps is significant enough to mask differences between bacterial communities from replicate samples. This was largely driven by greater variability in detection of rare bacteria (relative abundance water use. This suggests hydraulic changes (driven by changes in water demand) contribute to shaping the bacterial community in bulk drinking water over diurnal time-scales.

    Full Text Available Making pro-environmental behavior changes can be difficult, particularly when these changes challenge daily routines and comfortable lifestyles. We designed and implemented an eco-representative intervention program to help students reduce their energy use by proactively coping with barriers to pro-environmental behavior change, and then communicate effective behavior change strategies to student peers. Twenty-nine first-year college students participated in a four-week proactive coping training to change five environmentally impactful behaviors and then spread behavior change messages to fellow residents during a two-week energy challenge. Eco-reps successfully changed their own behaviors in a pro-environmental direction by generating important barriers and successful facilitators for behavior change, and eco-rep residence halls were more likely to reduce energy and maintain reductions compared to non-eco-rep halls. Implications for future environmental behavior change interventions are discussed.

    Full Text Available The impact of environmental conditions for transmitting sensory cues and the ability of crayfish to utilize olfaction and vision were examined in regards to social interactive behavior. The duration and intensity of interactions were examined for conspecific crayfish with different sensory abilities. Normally, vision and chemosensory have roles in agonistic communication of Procambarus clarkii; however, for the blind cave crayfish (Orconectes australis packardi, that lack visual capabilities, olfaction is assumed to be the primary sensory modality. To test this, we paired conspecifics in water and out of water in the presence and absence of white light to examine interactive behaviors when these various sensory modalities are altered. For sighted crayfish, in white light, interactions occurred and escalated; however, when the water was removed, interactions and aggressiveness decreased, but, there was an increase in visual displays out of the water. The loss of olfaction abilities for blind cave and sighted crayfish produced fewer social interactions. The importance of environmental conditions is illustrated for social interactions among sighted and blind crayfish. Importantly, this study shows the relevance in the ecological arena in nature for species survival and how environmental changes disrupt innate behaviors.

    This paper's objective is to apply Intervention Mapping, a planning process for the systematic development of theory- and evidence-based health promotion interventions, to the development of interventions to promote energy conservation behavior. Intervention Mapping (IM) consists of six steps: needs assessment, program objectives, methods and applications, program development, planning for program implementation, and planning for program evaluation. Examples from the energy conservation field are provided to illustrate the activities associated with these steps. It is concluded that applying IM in the energy conservation field may help the development of effective behavior change interventions, and thus develop a domain specific knowledge-base for effective intervention design. - Highlights: > Intervention Mapping (IM) is a planning process for developing evidence-based interventions.> IM takes a problem-driven rather than theory-driven approach. > IM can be applied to the promotion of energy-conservation in a multilevel approach. > IM helps identifying determinants of behaviors and environmental conditions. > IM helps selecting appropriate theory-based methods and practical applications.

  16. Mobile applications for chronic disease self-management : building a bridge for behavior change

    2015-10-01

    Full Text Available Background One of the biggest challenges in the future of healthcare is the rising prevalence of chronic, non-communicable diseases. In high-income countries seven out of ten leading risk factors of death are caused by the way people eat, drink or move. Health behavior patterns are considered to account for 40 % of early mortality. If nothing changes, from 2011 until 2030 the cost of chronic disease in the whole world may reach 47 trillion dollars. It is clear that chronic disease care needs to change. Today people with chronic disease spend less than 0,1 % of their time yearly in direct contact with healthcare and guidance. The rest of the time they are under the influence of family, colleagues, acquaintances, media and all the conflicting information from them. Digital elements are emerging in healthcare. Some of these digital elements emerging are mobile applications. Of all the people in Finland, 70 % own a smartphone. These devices are often in the proximity of their owner; in a pocket or a purse, making them easy and fast to use for various purposes. This is why they can also prove to be useful tools for personal healthcare and chronic disease self-management support, for example for recording diet and exercise related values as well as various disease specific values like blood glucose or blood pressure measurements. They also enable two-way interaction with healthcare professionals and patients in their everyday life. This requires well designed applications that affect the patient’s health behavior and are tempting to use. According to research, this is not always the case. Aim The aim of this thesis study was to find out how multipurpose mobile applications intended for chronic disease self-management implement known behavior change techniques in order to change behavior, and to find out how they utilize known gamification features in order to maintain the change. The purpose of this study was to create a new, multidisciplinary

    Full Text Available INTRODUCTION: Advance directives have traditionally been considered the gold standard for advance care planning. However, recent evidence suggests that advance care planning involves a series of multiple discrete behaviors for which people are in varying stages of behavior change. The goal of our study was to develop and validate a survey to measure the full advance care planning process. METHODS: The Advance Care Planning Engagement Survey assesses "Process Measures" of factors known from Behavior Change Theory to affect behavior (knowledge, contemplation, self-efficacy, and readiness, using 5-point Likert scales and "Action Measures" (yes/no of multiple behaviors related to surrogate decision makers, values and quality of life, flexibility for surrogate decision making, and informed decision making. We administered surveys at baseline and 1 week later to 50 diverse, older adults from San Francisco hospitals. Internal consistency reliability of Process Measures was assessed using Cronbach's alpha (only continuous variables and test-retest reliability of Process and Action Measures was examined using intraclass correlations. For discriminant validity, we compared Process and Action Measure scores between this cohort and 20 healthy college students (mean age 23.2 years, SD 2.7. RESULTS: Mean age was 69.3 (SD 10.5 and 42% were non-White. The survey took a mean of 21.4 minutes (±6.2 to administer. The survey had good internal consistency (Process Measures Cronbach's alpha, 0.94 and test-retest reliability (Process Measures intraclass correlation, 0.70; Action Measures, 0.87. Both Process and Action Measure scores were higher in the older than younger group, p<.001. CONCLUSION: A new Advance Care Planning Engagement Survey that measures behavior change (knowledge, contemplation, self-efficacy, and readiness and multiple advance care planning actions demonstrates good reliability and validity. Further research is needed to assess whether survey

    Full Text Available Introduction: Current Thermal cycling units fail to simulate the drinking behaviors, and oral balancing temperature. They cannot also simulate other oral conditions such as drink coloring, and chemicals like tea, coffee, carbonated and noncarbonated, citrus juices as well as alcoholic and nonalcoholic drinks and also saliva and milk itself. The main objective of this study is to introduce the designing and manufacturing the first Drinking Simulator Unit (DSU that reproduces the thermal, color and chemicalcycling as well as the drinking behavior and oral temperature in lab conditions uniquely. Methods: The invented system generally has two parts: the hardware and the software parts. The hardware consists of the mechanical and electronic parts. The software part is responsible for controlling the heating and cooling systems, electric valves, the pumps, and automatic filling systems of tanks as well as the sensors of the machine. Results: DSU is the first unit can reproduce the thermal, color and chemical cycling as well as the drinking behavior and oral temperature in lab conditions. Different kinds of colored and acidic drinks and also other chemical materials such as bleaching substances as well as detergents and antiseptics used for dentistry, industrial and medical purposes can be tested by DSU. DSU has also to be considered as an appliance performing in-vitro researches on dental structures. Conclusion: The invented system can greatly improve and validate the results of such researches.

    Research on mechanisms of behavior change provides an innovative method to improve treatment for addictive behaviors. An important extension of mechanisms of change research involves the use of translational approaches, which examine how basic biological (i.e., brain-based mechanisms) and behavioral factors interact in initiating and sustaining positive behavior change as a result of psychotherapy. Articles in this special issue include integrative conceptual reviews and innovative empirical research on brain-based mechanisms that may underlie risk for addictive behaviors and response to psychotherapy from adolescence through adulthood. Review articles discuss hypothesized mechanisms of change for cognitive and behavioral therapies, mindfulness-based interventions, and neuroeconomic approaches. Empirical articles cover a range of addictive behaviors, including use of alcohol, cigarettes, marijuana, cocaine, and pathological gambling and represent a variety of imaging approaches including fMRI, magneto-encephalography, real-time fMRI, and diffusion tensor imaging. Additionally, a few empirical studies directly examine brain-based mechanisms of change, whereas others examine brain-based indicators as predictors of treatment outcome. Finally, two commentaries discuss craving as a core feature of addiction, and the importance of a developmental approach to examining mechanisms of change. Ultimately, translational research on mechanisms of behavior change holds promise for increasing understanding of how psychotherapy may modify brain structure and functioning and facilitate the initiation and maintenance of positive treatment outcomes for addictive behaviors.

    Research has shown a strong pilot preference for predictive information of aircraft system status in the flight deck. However, changes in pilot behavior associated with using this predictive information have not been ascertained. The study described here quantified these changes using three types of predictive information (none, whether a parameter was changing abnormally, and the time for a parameter to reach an alert range) and three initial time intervals until a parameter alert range was reached (ITIs) (1 minute, 5 minutes, and 15 minutes). With predictive information, subjects accomplished most of their tasks before an alert occurred. Subjects organized the time they did their tasks by locus-of-control with no predictive information and for the 1-minute ITI, and by aviatenavigate-communicate for the time for a parameter to reach an alert range and the 15-minute conditions. Overall, predictive information and the longer ITIs moved subjects to performing tasks before the alert actually occurred and had them more mission oriented as indicated by their tasks grouping of aviate-navigate-communicate.

    More than 700,000 people are thought to be HIV positive in Thailand. A booming sex industry and social attitudes which support the male patronage of prostitutes are major factors in the spread of disease in the country. A 4-day workshop on sexual behavior and AIDS in Thailand was attended by representatives from Burma, Cambodia, China, Indonesia, Malaysia, the Philippines, Thailand, and Vietnam. According to the Joint UN Program on HIV/AIDS (UNAIDS), the percentage of military conscripts in northern Thailand who visited a brothel in the past year fell from 58% in 1991 to 23% in 1995, while the percentage of recruits using condoms during their most recent brothel visits increased from 60% to 90% over the same period. Statistics from the Thai Public Health Ministry indicate that the percentage of men in the general population who used condoms when visiting a brothel increased from 40% in 1990 to 90% in 1994. Furthermore, a nationwide survey among military conscripts found the prevalence of HIV infection fell from 3.7% in 1993 to 2.5% in 1995, with the downward trend continuing in 1996. This success in reducing the level of sexual risk behavior and the incidence of HIV infection in Thailand lends hope for the possibility of changing the course of the HIV/AIDS epidemic elsewhere.

    Substance use disorders are credited with greater amounts of death and illness than all other preventable health problems. Billions of dollars are spent on efforts to control drug supplies and fund various treatment approaches, but relatively little resources have been directed towards investigating how environmental conditions can contribute to or detract from substance user’s individual motivation to change behavior. Hurricane Katrina caused untold property damage and upheaval, in addition to the vast numbers of people whose lives it drastically affected. This article examines how surviving this ordeal, subsequent evacuation, and eventual resettlement in New Orleans or re-location to a different city (in this case, Houston) impacted individuals’ motivation to change their substance use patterns and behaviors. This article’s approach is grounded in the values of the social work profession and examines: 1) the role of life events in motivating change of substance using behaviors in the absence of formal treatment interventions; and 2) participant resilience in overcoming the adversities inherent to this disaster.

    Adaptive behavior change is supported by executive control processes distributed throughout a prefrontal-striatal-parietal network. Yet, the temporal dynamics of regions in the network have not been characterized. Using functional magnetic resonance imaging (fMRI), we tracked changes brain activation while subjects initiated and inhibited responding in accordance with changes in reinforcement rate. During imaging, subjects completed a free-operant task that involved repeated transitions between fixed-ratio reinforcement and extinction (RF:EXT), where reinforcement rate decreased and responding was inhibited, and between extinction and fixed-ratio reinforcement (EXT:RF), where reinforcement rate increased and responding was initiated. Our whole-brain temporal assessment revealed that transitions which required initiating and inhibiting responding prompted positive phasic responses in a prefrontal-parietal network, the insula and thalamus. However, response initiation prompted by an increase in reinforcement rate during the EXT:RF transition elicited positive phasic responses in reward-sensitive striatal regions. Furthermore, response inhibition prompted by a decrease in reinforcement rate during the RF:EXT transition elicited negative phasic responses in ventral frontal regions sensitive to value and contingency. Our findings highlight the temporal dynamics of a brain network that supports behavioral changes (initiation and inhibition) resulting from changes in local reinforcement rates.

    Caffeine-containing energy drinks have emerged as a public health concern due to their association with caffeine toxicity and alcohol use. Despite the fact that previous research has linked caffeine use in the form of coffee drinking to smoking, there is little research examining the association between energy drinks and smoking. The present study examines demographic and behavioral factors associated with energy drink use among a sample of rural Ohio Appalachian smokers. It was hypothesized that male gender, young age (21-30 years.) and alcohol use would be associated with energy drink use. A sample of adult smokers (n = 298) from Ohio Appalachian counties were interviewed regarding demographic and behavioral factors. Logistic regression analysis was used to assess the association between these factors and energy drink use. Seventy percent of Ohio Appalachian smokers studied had ever used an energy drink and 40 % had used an energy drink in the past month. Young age, male gender, and single marital status were associated with higher odds of ever having used an energy drink. Young age, and binge drinking were associated with higher odds of past 30-day use while abstinence from drinking was associated with lower odds of past 30-day use. Ohio Appalachian adult smokers had higher rates of energy drink use compared to previous estimates of ever or past month use found in other studies. The combined use of caffeine, nicotine, and alcohol warrants attention due to potential for health risk.

    Full Text Available Previous trials have demonstrated that sheep on a low protein diet and free access to water, and sheep dosed with boluses of NaCl intraruminally also with free access to water, showed decreases in urea loss via the urine compared to control animals. We monitored urea excretion in sheep on a relatively poor protein diet when they were exposed to saline drinking water, i.e. they were unable to vary their intake of NaCl:water. Sheep on isotonic saline drinking water (phase 3 excreted significantly more urea via the urine (284 mM/day compared to phase 1 when they were on non-saline drinking water (urea excretion = 230 mM/day and phase 2 when they were on half isotonic saline drinking water (urea excretion = 244 mM/day.This finding was explained by the high glomerular filtration rate (GFR 91.9 ℓ/day, compared to 82.4 ℓ/day (phase 1 and 77.9 ℓ/day (phase 2, together with a significantly raised fractional excretion of urea (FEurea (51.1 % during this phase, and was in spite of the significantly lower plasma concentrations of urea in phase 3 compared to phase 1. The FEurea probably results from the osmotic diuresis caused by the salt. There were indications of a raised plasma antidiuretic hormone (ADH concentration and this would have opposed urea loss, as ADH promotes urea reabsorption. However, this ADH effect was probably counteracted to some extent by a low plasma angiotensin II concentration, for which again there were indications, inhibiting urea reabsorption during the phases of salt loading. As atrial natriuretic peptide both increases GFR and decrease sodium reabsorption from the tubule, it was probably instrumental in causing the increase in GFR and the increase in the fractional excretion of sodium (FENa.

    One of the main treatment challenges in alcohol use disorder (AUD) is the high rate of craving in combination with decreased cognitive functioning including impaired decision making and impulse control that often lead to relapse. Recent studies show that guanfacine, an α-2-adrenoceptor agonist and FDA-approved ADHD medication, attenuates stress-induced relapse of several drugs of abuse including alcohol. Here we evaluated guanfacine's effects on voluntary alcohol intake, the alcohol deprivation effect (ADE), alcohol seeking behavior, and cue/priming-induced reinstatement in Wistar rats that had voluntarily consumed alcohol for at least 2 months before treatment. In addition, guanfacine's ability to regulate glutamatergic neurotransmission was evaluated through electrophysiological recordings in medial prefrontal cortex (mPFC) slices prepared from long-term drinking rats (and alcohol-naive controls) that had received three daily guanfacine (0.6 mg/kg/day) or vehicle injections in vivo. Guanfacine decreased alcohol intake in high, but not low, alcohol-consuming rats and the effects were generally more long lasting than that of the AUD medication naltrexone. Repeated guanfacine treatment induced a long-lasting decrease in alcohol intake, persistent up to five drinking sessions after the last injection. In addition, guanfacine attenuated the ADE as well as alcohol seeking and cue/priming-induced reinstatement of alcohol seeking. Finally, subchronic guanfacine treatment normalized an alcohol-induced dysregulated glutamatergic neurotransmission in the mPFC. These results support previous studies showing that guanfacine has the ability to improve prefrontal connectivity through modulation of the glutamatergic system. Together with the fact that guanfacine appears to be clinically safe, these results merit evaluation of guanfacine's clinical efficacy in AUD individuals.

  12. Evidence that implementation intentions reduce drivers' speeding behavior: testing a new intervention to change driver behavior.

    2015-01-01

    Implementation intentions have the potential to break unwanted habits and help individuals behave in line with their goal intentions. We tested the effects of implementation intentions in the context of drivers' speeding behavior. A randomized controlled design was used. Speeding behavior, goal intentions and theoretically derived motivational pre-cursors of goal intentions were measured at both baseline and follow-up (one month later) using self-report questionnaires. Immediately following the baseline questionnaire, the experimental (intervention) group (N=117) specified implementation intentions using a volitional help sheet, which required the participants to link critical situations in which they were tempted to speed with goal-directed responses to resist the temptation. The control group (N=126) instead received general information about the risks of speeding. In support of the hypotheses, the experimental group reported exceeding the speed limit significantly less often at follow-up than did the control group. This effect was specific to 'inclined abstainers' (i.e., participants who reported speeding more than they intended to at baseline and were therefore motivated to reduce their speeding) and could not be attributed to any changes in goal intentions to speed or any other measured motivational construct. Also in line with the hypotheses, implementation intentions attenuated the past-subsequent speeding behavior relationship and augmented the goal intention - subsequent speeding behavior relationship. The findings imply that implementation intentions are effective at reducing speeding and that they do so by weakening the effect of habit, thereby helping drivers to behave in accordance with their existing goal intentions. The volitional help sheet used in this study is an effective tool for promoting implementation intentions to reduce speeding.

  13. Behavioral Change and Building Performance: Strategies for Significant, Persistent, and Measurable Institutional Change

    The people who use Federal buildings — Federal employees, operations and maintenance staff, and the general public — can significantly impact a building’s environmental performance and the consumption of energy, water, and materials. Many factors influence building occupants’ use of resources (use behaviors) including work process requirements, ability to fulfill agency missions, new and possibly unfamiliar high-efficiency/high-performance building technologies; a lack of understanding, education, and training; inaccessible information or ineffective feedback mechanisms; and cultural norms and institutional rules and requirements, among others. While many strategies have been used to introduce new occupant use behaviors that promote sustainability and reduced resource consumption, few have been verified in the scientific literature or have properly documented case study results. This paper documents validated strategies that have been shown to encourage new use behaviors that can result in significant, persistent, and measureable reductions in resource consumption. From the peer-reviewed literature, the paper identifies relevant strategies for Federal facilities and commercial buildings that focus on the individual, groups of individuals (e.g., work groups), and institutions — their policies, requirements, and culture. The paper documents methods with evidence of success in changing use behaviors and enabling occupants to effectively interact with new technologies/designs. It also provides a case study of the strategies used at a Federal facility — Fort Carson, Colorado. The paper documents gaps in the current literature and approaches, and provides topics for future research.

    Understanding how communities change requires examining how individuals' beliefs and behaviors are shaped by those around them. This paper investigates behavior change across a large social network following a recycling intervention in a New Zealand high school community. We used a mixed methods design, combining focus group data with social network analysis from two waves of a questionnaire that measured friendship networks; recycling and littering behaviors; perceived behavioral norms; and teacher, friend, and parent encouragement for these behaviors. Recycling behavior increased significantly over the course of our study. Supporting the importance of social networks in this context, both littering and recycling behavior showed clear social clustering. Further, the degree of change in an individuals' littering and recycling behavior across time was predicted by friends' prior behavior. Focus group data provided insight into students' perceptions of social interactions and how these contributed to littering and recycling behavior.

    Twenty-three infants (M = 13.7 months, SD = 3.73) and their primary caregivers were observed and video-taped in three 20-min play sessions. Over the course of a month, changes in infant behaviors and caregiver responsiveness to those behaviors were monitored. Repeated-measures ANOVAs indicated that caregiver responsiveness to infant object-related and dyadic behaviors significantly increased over the course of the sessions. However, the ANOVAs did not specify exactly which caregiver behaviors changed. Sequential data analysis revealed that caregivers specifically increased their use of dyadic vocal behaviors in response to all infant behaviors. This study reveals that although ANOVAs are useful for providing information about macro, overall changes in caregiver behavior, sequential data analysis is a useful tool for evaluating micro, moment-to-moment changes in behavior. With sequential analysis, specific behavioral patterns can be examined and, if necessary, steps can be taken to modify and monitor those behaviors over time. •Sequential data analysis was used to monitor changes in caregiver behavior.•Non-culture-specific behavioral codes and techniques were used to quantify caregiver responsiveness to infant object-related and dyadic behaviors.•When compared to ANOVA, sequential data analysis is more useful for assessing micro-level behavioral changes in infant-caregiver interactions.

    Absorbance, 3D fluorescence and ultrahigh resolution electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (ESI-FT-ICR-MS) were used to explain patterns in the removal of chromophoric and fluorescent dissolved organic matter (CDOM and FDOM) at the molecular level during drinking water production at four large drinking water treatment plants in Sweden. When dissolved organic carbon (DOC) removal was low, shifts in the dissolved organic matter (DOM) composition could not be detected with commonly used DOC-normalized parameters (e.g. specific UV254 absorbance - SUVA), but was clearly observed by using differential absorbance and fluorescence or ESI-FT-ICR-MS. In addition, we took a novel approach by identifying how optical parameters were correlated to the elemental composition of DOM by using rank correlation to connect optical properties to chemical formulas assigned to mass peaks from FT-ICR-MS analyses. Coagulation treatment selectively removed FDOM at longer emission wavelengths (450-600 nm), which significantly correlated with chemical formulas containing oxidized carbon (average carbon oxidation state ≥ 0), low hydrogen to carbon ratios (H/C: average ± SD = 0.83 ± 0.13), and abundant oxygen-containing functional groups (O/C = 0.62 ± 0.10). Slow sand filtration was less efficient in removing DOM, yet selectively targeted FDOM at shorter emission wavelengths (between 300 and 450 nm), which commonly represents algal rather than terrestrial sources. This shorter wavelength FDOM correlated with chemical formulas containing reduced carbon (average carbon oxidation state ≤ 0), with relatively few carbon-carbon double bonds (H/C = 1.32 ± 0.16) and less oxygen per carbon (O/C = 0.43 ± 0.10) than those removed during coagulation. By coupling optical approaches with FT-ICR-MS to characterize DOM, we were for the first time able to confirm the molecular composition of absorbing and fluorescing DOM selectively targeted during drinking

    Objective: Research on moderate drinking has focused on the average level of drinking. Recently, however, investigators have begun to consider the role of the pattern of drinking, particularly heavy episodic drinking, in mortality. The present study examined the combined roles of average drinking level (moderate vs. high) and drinking pattern (regular vs. heavy episodic) in 20-year total mortality among late-life drinkers. Method: The sample comprised 1,121 adults ages 55–65 years. Alcohol consumption was assessed at baseline, and total mortality was indexed across 20 years. We used multiple logistic regression analyses controlling for a broad set of sociodemographic, behavioral, and health status covariates. Results: Among individuals whose high level of drinking placed them at risk, a heavy episodic drinking pattern did not increase mortality odds compared with a regular drinking pattern. Conversely, among individuals who engage in a moderate level of drinking, prior findings showed that a heavy episodic drinking pattern did increase mortality risk compared with a regular drinking pattern. Correspondingly, a high compared with a moderate drinking level increased mortality risk among individuals maintaining a regular drinking pattern, but not among individuals engaging in a heavy episodic drinking pattern, whose pattern of consumption had already placed them at risk. Conclusions: Findings highlight that low-risk drinking requires that older adults drink low to moderate average levels of alcohol and avoid heavy episodic drinking. Heavy episodic drinking is frequent among late-middle-aged and older adults and needs to be addressed along with average consumption in understanding the health risks of late-life drinkers.

    Hoping to determine whether recent changes in marriage and fertility behavior are simply temporary or more permanent, the attitudes and values of young adults were compared to the recent trends. The data come from the 1987 wave of the National Survey of Children, which has tracked a nationally representative sample of young people since 1976. The following behaviors and their corresponding attitudes are discussed: sexual activity, pregnancy, nonmarital childbearing, abortion, marriage and cohabitation, and divorce. Also considered are how blacks and whites differ in their behavior and attitudes. Since the 1970s, the incidence of premarital intercourse has increased substantially among adolescents and has resulted in a rise in the pregnancy rate. Adolescents strongly disapprove of sexual activity among younger teens, but accept it for older adolescents. Nonmarital childbearing increased by about 50% from 1970 to 1987. Adolescents, however, generally hold negative attitudes toward adolescent pregnancy, and the majority of sexually experienced teens report wanting to avoid pregnancy. In 1985, over 40% of teens who became pregnant obtained an abortion. Adolescents are divided on the acceptability of abortion -- except in instances of rape, in which case most accept abortion. Young adults strongly favor delayed marriage and oppose divorce, feeling that couples should not get married unless they intend to stay together for life. About 1/2 of young adults approve of cohabitation and only 1/5 are opposed to nonmarital childbearing. Based on the policy implications of the findings, it is concluded that the attitudes and values of young adults do not reflect the demise of the family, as has been predicted.

  4. Drinks like a fish: zebra fish (Danio rerio) as a behavior genetic model to study alcohol effects.

    2000-12-01

    Zebra fish may be an ideal vertebrate model system for numerous human diseases with which the genetics and biological mechanisms of the disease may be studied. Zebra fish has been successfully used in developmental genetics, and recently, neurobiologists have also started to study this species. A potentially interesting target disease amenable for analysis with zebra fish is drug addiction, e.g. alcoholism. Although genetic tools to manipulate the genome of zebra fish are available, appropriate phenotypical testing methods are often lacking. In this paper, we describe basic behavioral tests to investigate the acute effects of alcohol on zebra fish. These behavioral paradigms will be useful for the genetic and biological analysis of acute and chronic drug effects as well as addiction. In addition to presenting findings for the acute effects of alcohol, we briefly describe our strategy for generating and screening mutants. We hope that our pilot work will facilitate the future development of behavioral tests and the use of zebra fish in the genetic analysis of the biological effects of drugs of abuse.

  5. Social marketing of condoms: selling protection and changing behavior.

    Social marketing of condoms in Zaire began in 1987 and sales rose to 8 million in 1990, a notable change from the previous situation where about half a million condoms were distributed by government health clinics only. Social marketing is the use of for-profit sales and marketing techniques for public health problem.s When the Zaire National AIDS Committee initiated social marketing of condoms, with the assistance of Population Services International, they had the experience of successful Asian programs of the 1970s, and the political sanction resulting from the AIDS threat to back them up. Efforts were made to find just the right product name, "Prudence," logo, package, color and slogan by consumer research. Prudence implies responsible behavior, capturing both the AIDS and STD prevention and the family planning markets. Consumers like the package and associate it with quality, since most condoms sold before in Zaire had no special packaging. Distribution outlets include 7000 retail shops, groceries, pharmacies, hotel, social clubs, 300 bars and even Congo River barges which sex workers frequent. The price was set close to that of a pack of gum for 3, or that of a bottle of beer for a dozen. Promotion is limited by a government ban of advertising in mass media, so point of purchase materials, special offers and promotional items are being used. Prudence condoms are now being marketed in Cameroon and Burundi.

    Organic matter (OM) causes many problems in drinking water treatment. It is difficult to monitor OM concentrations and character during treatment processes due to its complexity. Fluorescence spectroscopy is a promising tool for online monitoring. In this study, a unique dataset of fluorescence excitation emission matrixes (EEMs) (n = 867) was collected from all treatment stages of five drinking water treatment plants (WTPs) situated in diverse locations from subtropical to temperate climate. The WTPs incorporated various water sources, treatment processes and OM removal efficiencies (DOC removal 0%-68%). Despite these differences, four common fluorescence PARAFAC components were identified for characterisation of OM concentration and treatability. Moreover, fluorescence component ratios showed site-specific statistically significant correlations with OM removal, which contrasted with correlations between specific UV absorbance at 254 nm (SUVA) and OM removal that were not statistically significant. This indicates that use of fluorescence spectroscopy may be a more robust alternative for predicting DOC removal than UV spectroscopy. Based on the identified fluorescence components, four optical locations were selected in order to move towards single wavelength online OM monitoring.

    Full Text Available The purpose of this study is to investigate the impact of the leader’s change-promoting behavior on employee’s readiness for change and whether the organizational culture mediates this relationship. A sample of 205 responses is drawn from employees having junior or senior level of managerial responsibilities in Karachi. The method of both exploratory and confirmatory factor analyses is employed to evaluate the reliability and validity of the measurement model. The structural equation modeling method was then applied to examine the theoretical framework with the help of seven frequently reported goodness-of-fit indices. The results indicate that leader’s change-promoting behavior has a significant positive impact on change readiness and the organizational culture partially mediates the positive relationship between the leader’s change-promoting behavior and change readiness. The present study supports the theory of one of the six conceptual formations of change readiness that it is reflected as employee’s capacity to change. Therefore, managers should clearly advocate the desired change with the help of their own change-prompting behavior as well as establishing a trusting culture in their organization. Future studies may ascertain the impact of employees’ readiness for change in their commitment to change in the context of Pakistan which could further lead to passive or active change-related behaviors.

    Raising customer satisfaction in health-care organizations has been a priority for the past 5 years or more. Articles and books continue to be written on the topic and speeches and presentations are given to eager audiences of professionals who have a deep desire to improve customer satisfaction. Yet research indicates that customer satisfaction, on average, in the health-care industry barely has improved. This column will examine why some organizations, using the same best practice techniques and approaches for top customer satisfaction, achieve wonderful results as most others achieve meager results, at best. The answer to achieving top customer satisfaction lies in the leadership of the organization. When leaders change their thinking and behaviors, results will change.

  12. Granular flow behavior at sharp changes in slope

    2015-04-01

    This study extends some recent experiments and analyses performed by the authors to examine the behavior of granular flows along path characterised by sharp changes in slope. In particular, various series of experiments along a bi-linear broken slope (an inclined initial sector followed by a horizontal one) have been completed using a uniform (Hostun, 0.32 mm) sand and a uniform fine gravel (2 mm grains). 60 new have been performed by releasing different volumes (1.5, 2.1 and 5.1 L) on surfaces characterized by different slope angles (35-60°), type of materials (wood and plexiglass), with or without an erodible layer (sand), or in presence of a shallow water pond (0.5 cm). These geometrical features are typical of many large rock and snow avalanches, rock falls and of chalk flows. The latter are usually typical of coastal cliffs where a shallow water environment is typical. The evolution of the flow has been monitored through a laser profilometer at 120 Hz sampling frequency and high speed camera, and in this way it has been possible to follow the evolution of the flow and deposition, and to analyse the change in deposition mode at varying the slope angle, the material and the basal friction. This is an extremely interesting development in the study of the evolution of the deposition and of the final morphology typical of such phenomena, and can support the testing of numerical models. Propagation and deposition occur forward or backward accordingly to the slope angle and the basal friction. Forward movement and deposition occur at high slope angles and with low basal friction. The opposite is true for the backward deposition. The internal "layering" within the deposit is also strongly controlled by the combination of such parameters. The time evolution of the flow allowed to determine the velocity of flow and the mode of deposition through the analysis of the change in thickness, position of the front and of the flow tail. Presence of water reduces the runout of

    This study aimed to examine the interrelation of physical activity and fruit and vegetable intake. The influence of stage congruence between physical activity and fruit and vegetable intake on multiple behavior change was also investigated. Health behaviors, social-cognitions, and stages of change were assessed in 2693 adults at two points in time. Physical activity and fruit and vegetable intake were assessed 4 weeks after the baseline. Social-cognitions, stages as well as stage transitions across behavior domains were positively interrelated. Stage congruence was not related to changes in physical activity and fruit and vegetable intake. Physical activity and nutrition appear to facilitate rather than hinder each other. Having intentions to change both behaviors simultaneously does not seem to overburden individuals.

  16. Age-related striatal BOLD changes without changes in behavioral loss aversion

    2015-04-01

    Full Text Available Loss aversion (LA, the idea that negative valuations have a higher psychological impact than positive ones, is considered an important variable in consumer research. The literature on aging and behavior suggests older individuals may show more LA, although it is not clear if this is an effect of aging in general (as in the continuum from age 20 and 50 years, or of the state of older age (e.g., past age 65 years. We also have not yet identified the potential biological effects of aging on the neural processing of LA. In the current study we used a cohort of subjects with a 30 year range of ages, and performed whole brain functional MRI (fMRI to examine the ventral striatum/nucleus accumbens (VS/NAc response during a passive viewing of affective faces with model-based fMRI analysis incorporating behavioral data from a validated approach/avoidance task with the same stimuli. Our a priori focus on the VS/NAc was based on (1 the VS/NAc being a central region for reward/aversion processing, (2 its activation to both positive and negative stimuli, (3 its reported involvement with tracking LA. LA from approach/avoidance to affective faces showed excellent fidelity to published measures of LA. Imaging results were then compared to the behavioral measure of LA using the same affective faces. Although there was no relationship between age and LA, we observed increasing neural differential sensitivity (NDS of the VS/NAc to avoidance responses (negative valuations relative to approach responses (positive valuations with increasing age. These findings suggest that a central region for reward/aversion processing changes with age, and may require more activation to produce the same LA behavior as in younger individuals, consistent with the idea of neural efficiency observed with high IQ individuals showing less brain activation to complete the same task.

    Many cyclic changes during the menstrual cycle (temperature, depression, motor activity, pain sensitivity, etc.) are closely paralleled by changes in brain serotonin level. These changes, in turn, are associated with peripheral hormone levels which are comparatively regular and easily measured. Their measurement may be useful both in predicting behavior and in accounting for atypical menstrual-related behavior.

  18. Source to point of use drinking water changes and knowledge, attitude and practices in Katsina State, Northern Nigeria

    Onabolu, B.; Jimoh, O. D.; Igboro, S. B.; Sridhar, M. K. C.; Onyilo, G.; Gege, A.; Ilya, R.

    In many Sub-Saharan countries such as Nigeria, inadequate access to safe drinking water is a serious problem with 37% in the region and 58% of rural Nigeria using unimproved sources. The global challenge to measuring household water quality as a determinant of safety is further compounded in Nigeria by the possibility of deterioration from source to point of use. This is associated with the use of decentralised water supply systems in rural areas which are not fully reticulated to the household taps, creating a need for an integrated water quality monitoring system. As an initial step towards establishing the system in the north west and north central zones of Nigeria, The Katsina State Rural Water and Sanitation Agency, responsible for ensuring access to safe water and adequate sanitation to about 6 million people carried out a three pronged study with the support of UNICEF Nigeria. Part 1 was an assessment of the legislative and policy framework, institutional arrangements and capacity for drinking water quality monitoring through desk top reviews and Key Informant Interviews (KII) to ascertain the institutional capacity requirements for developing the water quality monitoring system. Part II was a water quality study in 700 households of 23 communities in four local government areas. The objectives were to assess the safety of drinking water, compare the safety at source and household level and assess the possible contributory role of end users’ Knowledge Attitudes and Practices. These were achieved through water analysis, household water quality tracking, KII and questionnaires. Part III was the production of a visual documentary as an advocacy tool to increase awareness of the policy makers of the linkages between source management, treatment and end user water quality. The results indicate that except for pH, conductivity and manganese, the improved water sources were safe at source. However there was a deterioration in water quality between source and

    The behavior along the potabilization process of 29 pharmaceuticals and 12 drugs of abuse identified from a total of 81 compounds at the intake of a drinking water treatment plant (DWTP) has been studied. The DWTP has a common treatment consisting of dioxychlorination, coagulation/flocculation and sand filtration and then water is splitted in two parallel treatment lines: conventional (ozonation and carbon filtration) and advanced (ultrafiltration and reverse osmosis) to be further blended, chlorinated and distributed. Full removals were reached for most of the compounds. Iopromide (up to 17.2 ng/L), nicotine (13.7 ng/L), benzoylecgonine (1.9 ng/L), cotinine (3.6 ng/L), acetaminophen (15.6 ng/L), erythromycin (2.0 ng/L) and caffeine (6.0 ng/L) with elimination efficiencies {>=}94%, were the sole compounds found in the treated water. The advanced treatment process showed a slightly better efficiency than the conventional treatment to eliminate pharmaceuticals and drugs of abuse. - Highlights: > The presence of pharmaceuticals and drugs of abuse in surface water was demonstrated. > Elimination in both potabilization processes reached levels >99% for most compounds. > Four pharmaceuticals and three drugs of abuse survived the potabilization process. - The efficiency of potabilization processes to eliminate or transform pharmaceuticals and illicit drugs is evaluated.

    This mixed methods study explores college students' readiness-to-change and receptivity to treatment for problem Internet overuse behaviors. Focus groups were conducted with 27 college students who self-identified as Internet over-users, and had experienced biopsychosocial problems related to Internet overuse. Participants completed standardized questionnaires assessing their Internet use and sociodemographic forms. Focus groups explored readiness to change problem Internet overuse behaviors and receptivity to treatment. Similar to college students with other addictive behaviors, students with problem Internet overuse fall along a continuum vis-à-vis readiness-to-change their behaviors. Over half of the participants were receptive to treatment for their problem Internet overuse behaviors.

    We compared reporting serial cross-sectional prevalence of sexual behavior over time, to reporting individual patterns of behavioral change in a cohort of homosexual men at a six-month interval. Aggregate prevalence rates underestimated the magnitude of change to safer practices, and failed to provide information on relapse to less safe practices. We conclude that it is important to report data based on individual fluctuations in behavior for the evaluation of change over time.

    Drinking water lakes are threatened globally and therefore in need of protection. To date, few studies have been carried out to investigate how the composition and dynamics of chromophoric dissolved organic matter (CDOM) in drinking water lakes are influenced by inflow rate. Such CDOM can lead to unpleasant taste and odor of the water and produce undesirable disinfection byproducts during drinking water treatment. We studied the drinking water Lake Qiandao, China, and found that the concentrations of suspended particulate matter (SPM) in the lake increased significantly with inflow rate (p water safety and requires higher removal efficiency of CDOM during drinking water treatment processes.

    Objective To study the relationship between drinking environment, attitudes and situation and alcohol-related health problems. Methods A sample of 2327 respondents was randomly collected from Wuhan, Hubei Province in China by a face-to-face interview. The structural equation modeling analysis was performed for the data collected. Results Both parents' drinking behaviors and respondents' drinking situation strongly impacted the alcohol-related problems and diseases. Friends' or peers' drinking behaviors influenced the respondents' drinking attitudes and behaviors. Males experienced more alcohol-related problems and diseases than females. Conclusions Comparatively, parents' drinking behaviors exert the most significant influence on drinkers. Therefore, it is beneficial to restrict parents' drinking behaviors for the offsprings and the whole society, and an intensive professional education in early motherhood is also necessary for Chinese women.

    2004-01-01

    The purpose of this evidence-based study is to investigate the impact of a multi-component intervention on health behavior change among office/computer workers in preventing repetitive strain injuries. Forty office workers employed in an administrative office in Michigan participated in this project. The subjects completed a comprehensive questionnaire at three different times in 1994 and 1995. The intervention took place between time 2 and time 3 and included posters, e-mail tips, mini-workshops, and activities of a Wellness Ergonomic Team. A theoretical model was tested to identify factors influencing healthy behaviors. Study findings revealed positive behavior change for 62% of the participants. The factors most strongly related to health behavior change appear to be self-efficacy, the intention to change one's behavior, and perceived health status. Better understanding of health behavior change coupled with ergonomic modifications is a significant step toward the prevention of repetitive strain injuries resulting from computer use.

    Objective To investigate the relationships between tea drinking behavior and nonalcoholic fatty liver diseases ( NAFLD ) so as to provide an easier way towards effective NAFLD prevention.Methods A case - control study was used to research the relation.A questionnaire was used to investigate the drinking tea behavior and NAFLD from the subjects who had a physical examination in a Chinese people's liberation army hospital during August and December, 2008.Results Significant differences in tea drinking behavior existed between the case group ( 82.3% ) and the control group ( 95.5% ) ( P <0.05 ), implying that tea drinking was a protecting factor for NAFLD ( OR =0.218 ).The protective effects increased with the duration of tea drinking.Further, the protective effects of green tea is more obvious than those of red tea ( P < 0.05 ).Conclusion The behavior of tea drinking is an protective factor against NAFLD.Green tea exhibits stronger protective effects than red tea.%目的 探讨饮茶习惯与非酒精性脂肪性肝病(NAFLD)的相关关系,为NAFLD提供简便易行的防治方法.方法 采用病例对照研究方法,以中国人民解放军某医院体检部2008年9-12月参加健康体检的人员为研究对象,调查NAFLD的患病情况和饮茶习惯,分析二者间的关系.结果 共调查147例NAFLD患者(病例组)和179例健康对照者(对照组).发现对照组中饮茶者所占比例(95.5%)显著高于病例组(82.3%),差异有统计学意义[χ2=15.095,P<0.05,OR=0.218,95%CI(0.095,0.497)],提示饮茶为NAFLD的保护性因素,且随着饮茶时间的增加该作用更明显.绿茶的保护性作用显著高于红茶(P<0.05).结论 饮茶对NAFLD有保护作用,且绿茶的保护作用更为明显,初步提示饮茶是一种较好的预防NAFLD的方法.

  10. Effect of changes in the deuterium content of drinking water on the hydrogen isotope ratio of urinary steroids in the context of sports drug testing.

    The hydrogen isotope ratio (HIR) of body water and, therefore, of all endogenously synthesized compounds in humans, is mainly affected by the HIR of ingested drinking water. As a consequence, the entire organism and all of its synthesized substrates will reflect alterations in the isotope ratio of drinking water, which depends on the duration of exposure. To investigate the effect of this change on endogenous urinary steroids relevant to doping-control analysis the hydrogen isotope composition of potable water was suddenly enriched from -50 to 200 ‰ and maintained at this level for two weeks for two individuals. The steroids under investigation were 5β-pregnane-3α,20α-diol, 5α-androst-16-en-3α-ol, 3α-hydroxy-5α-androstan-17-one (ANDRO), 3α-hydroxy-5β-androstan-17-one (ETIO), 5α-androstane-3α,17β-diol, and 5β-androstane-3α,17β-diol (excreted as glucuronides) and ETIO, ANDRO and 3β-hydroxyandrost-5-en-17-one (excreted as sulfates). The HIR of body water was estimated by determination of the HIR of total native urine, to trace the induced changes. The hydrogen in steroids is partly derived from the total amount of body water and cholesterol-enrichment could be calculated by use of these data. Although the sum of changes in the isotopic composition of body water was 150 ‰, shifts of approximately 30 ‰ were observed for urinary steroids. Parallel enrichment in their HIR was observed for most of the steroids, and none of the differences between the HIR of individual steroids was elevated beyond recently established thresholds. This finding is important to sports drug testing because it supports the intended use of this novel and complementary methodology even in cases where athletes have drunk water of different HIR, a plausible and, presumably, inevitable scenario while traveling.

  11. On their best behavior: how animal behavior can help determine the combined effects of species interactions and climate change.

    2013-09-01

    The increasingly appreciated link between climate change and species interactions has the potential to help us understand and predict how organisms respond to a changing environment. As this connection grows, it becomes even more important to appreciate the mechanisms that create and control the combined effect of these factors. However, we believe one such important set of mechanisms comes from species' behavior and the subsequent trait-mediated interactions, as opposed to the more often studied density-mediated effects. Behavioral mechanisms are already well appreciated for mitigating the separate effects of the environment and species interactions. Thus, they could be at the forefront for understanding the combined effects. In this review, we (1) show some of the known behaviors that influence the individual and combined effects of climate change and species interactions; (2) conceptualize general ways behavior may mediate these combined effects; and (3) illustrate the potential importance of including behavior in our current tools for predicting climate change effects. In doing so, we hope to promote more research on behavior and other mechanistic factors that may increase our ability to accurately predict climate change effects.

    Animals with incomplete cheeks (i.e. dogs and cats) need to move fluid against gravity into the body by means other than suction. They do this by lapping fluid with their tongue. When a dog drinks, it curls its tongue posteriorly while plunging it into the fluid and then quickly withdraws its tongue back into the mouth. During this fast retraction fluid sticks to the ventral part of the curled tongue and is drawn into the mouth due to inertia. We show several variations of this drinking behavior among many dog breeds, specifically, the relationship between tongue dynamics and geometry, lapping frequency, and dog weight. We also compare the results with the physical experiment of a rounded rod impact onto a fluid surface. Supported by NSF PoLS #1205642.

    2016-09-01

    Relatively little research has examined how peer communication influences alcohol consumption. In a sample of mandated college students, we differentiate conversations about drinking from conversations about harm prevention and provide evidence for the validity of these communication constructs. Students who violated campus alcohol policies and were referred for alcohol sanctions (N = 345) reported on drinking patterns, use of protective behavioral strategies, perceived descriptive norms for close friends, and serving as social leader among their friends; they also reported on the frequency of conversations about drinking, about drinking safety, and about risk reduction efforts. Predicted correlations were found among types of communication and conceptually related variables. General communication was related to consumption but not protective behavioral strategies, whereas safety/risk reduction conversations correlated positively with all protective behavioral strategies. Both types of communication were associated with social leadership. Safety communication moderated the relationship between peer descriptive norms and drinks per week; more frequent talking about safety attenuated the norms-consumption relationship. Peer communication about both drinking and safety may serve as targets for change in risk reduction interventions for mandated college students.

    2011-12-01

    This article investigates a change in the structuring of work time, using a natural experiment to test whether participation in a corporate initiative (Results Only Work Environment; ROWE) predicts corresponding changes in health-related outcomes. Drawing on job strain and stress process models, we theorize greater schedule control and reduced work-family conflict as key mechanisms linking this initiative with health outcomes. Longitudinal survey data from 659 employees at a corporate headquarters shows that ROWE predicts changes in health-related behaviors, including almost an extra hour of sleep on work nights. Increasing employees' schedule control and reducing their work-family conflict are key mechanisms linking the ROWE innovation with changes in employees' health behaviors; they also predict changes in well-being measures, providing indirect links between ROWE and well-being. This study demonstrates that organizational changes in the structuring of time can promote employee wellness, particularly in terms of prevention behaviors.

    1993-02-01

    This study examined the impact of social problem-solving training on the behavior of five aggressive boys. Acquisition of problem-solving skills and changes in classroom behavior were evaluated using multiple-baseline designs within and across subjects. A generalization-programming procedure to promote the use of problem-solving skills in the natural environment was introduced across children in multiple-baseline fashion. Direct observation and behavior ratings were used to evaluate the treatment. Results indicated that each subject acquired the problem-solving skills at levels comparable to well-adjusted peers. Only one child showed behavioral improvement coincident with problem-solving skill acquisition. Three others showed moderate behavior change after the generalization-programming procedure was introduced. Only one child's gains on teacher ratings were maintained at the 6-month followup. The results suggest that cognitive-behavioral treatment of childrens' aggressive behavior may produce changes of limited magnitude and durability.

    1977-01-01

    The influence of behavior that immediately precedes a reinforced target response on the effectiveness of a reinforcement contingency was examined in two experiments with mentally retarded children in a special-education classroom. Two reinforcement schedules were examined in each experiment. For each schedule, a prespecified period of attentive behavior served as the target response. The schedules differed in whether inattentive or attentive behavior was required immediately to precede the target response. These schedules were examined with one child in a simultaneous treatment design using praise as the reinforcer (Experiment I), and with two children in separate reversal designs using tokens as the reinforcer (Experiment II). While attentive behavior increased under each schedule, the increase was greater when attentive rather than inattentive behavior preceded the reinforced response. The results indicated that the effect of a contingency may be determined not only by the specific response reinforced but also by the behavior that immediately precedes that response.

    Wesensten, Nancy J

    2014-10-01

    Whether caffeine and energy drink consumption presents a critical emerging health problem is not currently known. Available evidence suggests that energy drink consumption represents a change in the ways in which individuals in the United States consume caffeine but that the amount of caffeine consumed daily has not appreciably increased. In the present review, the question of whether Americans are sleep deprived (a potential reason for using caffeine) is briefly explored. Reported rates of daily caffeine consumption (based on beverage formulation) and data obtained from both civilian and military populations in the United States are examined, the efficacy of ingredients other than caffeine in energy drinks is discussed, and the safety and side effects of caffeine are addressed, including whether evidence supports the contention that excessive caffeine/energy drink consumption induces risky behavior. The available evidence suggests that the main legitimate concern regarding caffeine and energy drink use is the potential negative impact on sleep but that, otherwise, there is no cause for concern regarding caffeine use in the general population.

    Rasmussen, D D; Mitton, D R; Larsen, S A; Yellon, S M

    2001-08-01

    Pineal melatonin secretion has been reported to commonly decrease with aging, whereas intra-abdominal adiposity, plasma insulin and plasma leptin levels tend to increase. We recently demonstrated that daily melatonin administration starting at middle age suppressed male rat intra-abdominal fat, plasma leptin and plasma insulin to youthful levels, suggesting that aging-related changes in pineal melatonin secretion and in energy regulation may be functionally related. Accordingly, we have now investigated the effects of daily melatonin treatment on energy regulation in young versus middle-aged male Sprague Dawley rats. Addition of melatonin to the drinking water (0.2 microg/mL) produced nocturnal and diurnal plasma melatonin concentrations in middle-aged rats (12 months) equivalent to those of young adult (5 months) rats. Administration of this melatonin dosage every day for 10 wk starting at 10 months of age suppressed (P melatonin for 10 wk starting at 3 months of age did not significantly alter (P> 0.10) any of these parameters. The melatonin administration stimulated (102%, P melatonin begins at middle age, coincident with and likely dependent upon the aging-associated decline in endogenous pineal melatonin secretion. These results further suggest that appropriate melatonin supplementation may potentially provide therapy or prophylaxis not only for the insulin resistance, increased intra-abdominal fat and resulting pathologies that occur with aging, but also for some aging-associated behavioral changes.

    Chaves, Covadonga; Park, Crystal L

    2016-08-01

    This longitudinal study applied a stress and coping model to examine the differential pathways of perceived positive and negative health behavior changes. Participants with congestive heart failure completed self-report measures of psychological resources, coping strategies, and perceived behavior changes and were assessed again 6 months later. Patients with higher positive affect and spiritual well-being reported more positive health behavior changes over time, effects mediated by approach coping. Alternatively, patients with lower psychological resources reported more negative behavior changes over time, effects mediated by avoidance coping. The results suggest that different psychological resources are related to different types of coping which, in turn, are associated with perceived positive or negative changes in health behavior over time.

    Patients with diabetes mellitus (DM) need psychological support throughout their life span from the time of diagnosis. The psychological make-up of the patients with DM play a central role in self-management behaviors. Without patient's adherence to the effective therapies, there would be persistent sub-optimal control of diseases, increase diabetes-related complications, causing deterioration in quality of life, resulting in increased healthcare utilization and burden on healthcare systems. However, provision of psychosocial support is generally inadequate due to its challenging nature of needs and demands on the healthcare systems. This review article examines patient's psychological aspects in general, elaborates in particular about emotion effects on health, and emotion in relation to other psychological domains such as cognition, self-regulation, self-efficacy and behavior. Some descriptions are also provided on willpower, resilience, illness perception and proactive coping in relating execution of new behaviors, coping with future-oriented thinking and influences of illness perception on health-related behaviors. These psychological aspects are further discussed in relation to DM and interventions for patients with DM. Equipped with the understanding of the pertinent nature of psychology in patients with DM; and knowing the links between the psychological disorders, inflammation and cardiovascular outcomes would hopefully encourages healthcare professionals in giving due attention to the psychological needs of patients with DM.

    Background: Behavioral dentistry is an interdisciplinary science which needs to be learned, practiced, and reinforced in order to provide quality dental care in children. Aim: To assess the anxiety experienced during dental treatment in preschool children with/without rotary instruments using behavioral scale. Study and Design: Sixty pediatric patients of preschool age with bilateral occlusal carious lesions extending into dentin were selected for the study. Carious lesions were removed using conventional rotary instruments on one side and Papacarie – chemomechanical caries removal of approach on contra lateral side. Both cavities were restored with glass ionomer cement (Fuji IX). Anxiety scores were determined using ‘Modified Child Dental Anxiety Scale’ (Wong et al, 1998) during the various clinical stages of the treatment course. Results: Children experienced relaxed behavior when subjected to Papacarie method of caries removal compared to conventional method using rotary instruments. Conclusion: This study helped us to provide behavioral measures and introduce children to dentistry in a nonthreatening setting. PMID:25254189

    Under uncertainty, human and animal collectives often respond stochastically to events they encounter. Human or animal individuals behave depending on others' actions, and sometimes follow choices that are sub-optimal for individuals. Such mimetic behaviors are enhanced during emergencies, creating collective behavior of a group. A stock market that is about to crash, as markets did immediately after the Lehman Brothers bankruptcy, provides illustrative examples of such behaviors. We provide empirical evidence proving the existence of collective behavior among stock market participants in emergent situations. We investigated the resolution of extreme supply-and-demand order imbalances by increased balancing counter orders: buy and sell orders for excess supply and demand respectively, during times of price adjustment, so-called special quotes on the Tokyo Stock Exchange. Counter orders increase positively depending on the quantity of revealed counter orders: the accumulated orders in the book until then. Statistics of the coming counter order are well described using a logistic regression model with the ratio of revealed orders until then to the finally revealed orders as the explanatory variable. Results given here show that the market participants make Bayesian estimations of optimal choices to ascertain whether to order using information about orders of other participants.

    Patients with diabetes mellitus(DM) need psychological support throughout their life span from the time of diagnosis. The psychological make-up of the patients with DM play a central role in self-management behaviors. Without patient’s adherence to the effective therapies, there would be persistent sub-optimal contro of diseases, increase diabetes-related complications,causing deterioration in quality of life, resulting in increased healthcare utilization and burden on healthcare systems. However, provision of psychosocial support is generally inadequate due to its challenging nature of needs and demands on the healthcare systems. This review article examines patient’s psychological aspects in general, elaborates in particular about emotion effects on health, and emotion in relation to other psychological domains such as cognition, self-regulation,self-efficacy and behavior. Some descriptions are also provided on willpower, resilience, illness perception and proactive coping in relating execution of new behaviors,coping with future-oriented thinking and influences of illness perception on health-related behaviors. These psychological aspects are further discussed in relationto DM and interventions for patients with DM. Equipped with the understanding of the pertinent nature of psychology in patients with DM; and knowing the links between the psychological disorders, inflammation and cardiovascular outcomes would hopefully encourages healthcare professionals in giving due attention to the psychological needs of patients with DM.

    The present study examined the effectiveness of expressive writing in reducing drinking behavior. We expected that students prompted to write about negative drinking experiences would show greater decreases in future drinking intentions compared to the neutral and the positive writing conditions. We also expected that decreases in drinking intentions following the writing prompts might differ based on current drinking and AUDIT scores. Participants included 200 (76% female) undergraduates who completed measures of their current drinking behavior. They were then randomly assigned to either write about: a time when they had a lot to drink that was a good time (Positive); a time when they had a lot to drink that was a bad time (Negative); or their first day of college (Neutral), followed by measures assessing intended drinking over the next three months. Results revealed that participants intended to drink significantly fewer drinks per week and engage in marginally fewer heavy drinking occasions after writing about a negative drinking occasion when compared to control. Interactions provided mixed findings suggesting that writing about a positive event was associated with higher drinking intentions for heavier drinkers. Writing about a negative event was associated with higher intentions among heavier drinkers, but lower intentions among those with higher AUDIT scores. This research builds on previous expressive writing interventions by applying this technique to undergraduate drinkers. Preliminary results provide some support for this innovative strategy but also suggest the need for further refinement, especially with heavier drinkers.

    Full Text Available Introduction The commercial egg industry commonly uses induced molt procedures to rejuvenate flocks for a second or third laying cycle. Molting may be induced by feed withdrawal for up to 10 days (7, water withdrawal for 2 days (19, or both, along with a reduction of day length (14. Such programs cause concern about animal welfare because it is thought that they may be harmful to hens (28. Given the concerns for potential bird stress, various methods of nutrient restriction that would avoid long term feed withdrawal have been investigated (20, 24. One of the alternative methods for molt induction is high-dietary Zn (4. Materials and Methods In this study, a total of 30 Hy-line W-36 leghorn hens (at 50 wk old (1400 ± 150 g, were randomly assigned to 5 replicate. Ten cages (3 hens in each cage on both the upper and lower tiers were considered to observe behavior patterns. Data recording of predetermined behavioral patterns were carried out using five Camera Digital Video Recorder Multiplexer System. Behavior recording began at 9:00 h each day and ended at 11:00 h and a second observation starting at 16:00 p.m and ended at 18:00 p.m. Total of ten cages (containing 3 hens/ cage (30 hens total were used to collect 5 behaviors (feeding, drinking, nonnutritive pecking, preening and aggression pecking and one posture (sitting. The following ethogram was adopted from Webster (27 feeding defined as pecking behavior directed toward the feed trough or toward a neighboring feed trough. Drinking was defined as the appearance of ingesting water from the nipple at the near of the cage. Nonnutritive pecking was defined as non aggressive pecking at anything other than feed, which included cage pecking, feather pecking, bill pecking and air pecking. Preening behavior involved the manipulation of the plumage with the beak. Aggressive was the sum of pecks that occurred within a cage or between neighboring cages. Sitting was defined as a crouched posture with shanks

    Increasing rates of obesity among children ages 12 to 19 years have led to recommendations to alter the school food environment. The purpose of this study was to determine whether there are associations between an altered school food environment and food choices of middle school students both in and outside of school. In a midsized western city, two of six middle schools allowed only bottled water in vending machines, only milk and fruit on à la carte menus, and offered a seasonal fruit and vegetable bar. Three years after the intervention was initiated, seventh- and eighth-grade students attending the two intervention schools and four control middle schools were surveyed about their food choices. A total of 2,292 surveys were completed. Self-reported frequency of consumption for nine food groups in the survey was low; consumption was higher outside than in school. Boys consumed more milk than girls although girls consumed more fruits and vegetables. Significant socioeconomic differences existed. Compared with students who paid the full lunch fee, students qualifying for free and reduced-price meals consumed more milk and juice in schools but less outside school; more candy and energy drinks in school; and more sweet drinks, candy, pastries, and energy drinks outside school. Students in intervention schools were 24% more likely to consume milk outside school, 27% less likely to consume juice in school, and 56% less likely to consume sweet pastries in school. There were no differences in fruit and vegetable consumption reported by children in control and intervention schools. Overall, there was a positive association between a modified school food environment and student food behavior in and outside school. Policies related to the school food environment are an important strategy to address the obesity epidemic in our country.

    Alcohol binge-drinking during adolescence is a serious public health concern with long-term consequences. We used RNA sequencing to assess the effects of excessive adolescent ethanol binge-drinking on gene expression in the dorsal raphe nucleus (DRN) of alcohol preferring (P) rats. Repeated binges across adolescence (three 1h sessions across the dark-cycle per day, 5 days per week for 3 weeks starting at 28 days of age; ethanol intakes of 2.5-3 g/kg/session) significantly altered the expression of approximately one-third of the detected genes. Multiple neurotransmitter systems were altered, with the largest changes in the serotonin system (21 of 23 serotonin-related genes showed decreased expression) and GABA-A receptors (8 decreased and 2 increased). Multiple neuropeptide systems were also altered, with changes in the neuropeptide Y and corticotropin-releasing hormone systems similar to those associated with increased drinking and decreased resistance to stress. There was increased expression of 21 of 32 genes for potassium channels. Expression of downstream targets of CREB signaling was increased. There were also changes in expression of genes involved in inflammatory processes, axonal guidance, growth factors, transcription factors, and several intracellular signaling pathways. These widespread changes indicate that excessive binge drinking during adolescence alters the functioning of the DRN and likely its modulation of many regions of the central nervous system, including the mesocorticolimbic system.

  20. Planning versus action: Different decision-making processes predict plans to change one's diet versus actual dietary behavior.

    Kiviniemi, Marc T; Brown-Kramer, Carolyn R

    2015-05-01

    Most health decision-making models posit that deciding to engage in a health behavior involves forming a behavioral intention which then leads to actual behavior. However, behavioral intentions and actual behavior may not be functionally equivalent. Two studies examined whether decision-making factors predicting dietary behaviors were the same as or distinct from those predicting intentions. Actual dietary behavior was proximally predicted by affective associations with the behavior. By contrast, behavioral intentions were predicted by cognitive beliefs about behaviors, with no contribution of affective associations. This dissociation has implications for understanding individual regulation of health behaviors and for behavior change interventions.

  1. Does Product Placement Change Television Viewers' Social Behavior?

    Directory of Open Access Journals (Sweden)

    Elizabeth Levy Paluck

    Full Text Available To what extent are television viewers affected by the behaviors and decisions they see modeled by characters in television soap operas? Collaborating with scriptwriters for three prime-time nationally-broadcast Spanish-language telenovelas, we embedded scenes about topics such as drunk driving or saving money at randomly assigned periods during the broadcast season. Outcomes were measured unobtrusively by aggregate city- and nation-wide time series, such as the number of Hispanic motorists arrested daily for drunk driving or the number of accounts opened in banks located in Hispanic neighborhoods. Results indicate that while two of the treatment effects are statistically significant, none are substantively large or long-lasting. Actions that could be taken during the immediate viewing session, like online searching, and those that were relatively more integrated into the telenovela storyline, specifically reducing cholesterol, were briefly affected, but not behaviors requiring sustained efforts, like opening a bank account or registering to vote.

    2005-01-01

    This paper reviews recent work which points to critical neural circuitry involved in lasting changes in anxiety like behavior following unprotected exposure of rats to cats (predator stress). Predator stress may increase anxiety like behavior in a variety of behavioral tests including: elevated plus maze, light dark box, acoustic startle, and social interaction. Studies of neural transmission in two limbic pathways, combined with path and covariance analysis relating physiology to behavior, suggest long term potentiation like changes in one or both of these pathways in the right hemisphere accounts for stress induced changes in all behaviors changed by predator stress except light dark box and social interaction. Findings will be discussed within the context of what is known about neural substrates activated by predator odor.

    Mass media campaigns designed to alter societal views and individual behaviors about back pain have been undertaken and evaluated in multiple countries. In contrast to the original Australian campaign, subsequent campaigns have been less successful, with improvements observed in beliefs without the corresponding changes in related behaviors. This article summarizes the results of a literature review, expert panel, and workshop held at the Melbourne International Forum XI: Primary Care Research on Low Back Pain in March 2011 on the role and interplay of various social behavior change strategies, including public education, law and legislation, healthy public policy, and social marketing in achieving a sustained reduction in the societal burden of back pain. Given the complexities inherent to health-related behaviors change, the Rothschild framework is applied in which behavior change strategies are viewed on a continuum from public education at one end through law and health policy at the other. Educational endeavors should likely be augmented with social marketing endeavors and supportive laws and health policy to foster sustained change in outcomes such as work disability and health utilization. Practical suggestions are provided for future interventions aimed at changing back pain-related behaviors. Evaluation of previous back pain mass media campaigns reveals that education alone is unlikely to foster positive and persisting behavioral change without concomitant strategies.

    Background Driving after the consumption of alcohol represents a significant problem globally. Individual prevention countermeasures such as personalized mobile apps aimed at preventing such behavior are widespread, but there is little research on their accuracy and evidence base. There has been no known assessment investigating the quality of such apps. Objective This study aimed to determine the quality and accuracy of apps for drink driving prevention by conducting a review and evaluation of relevant mobile apps. Methods A systematic app search was conducted following PRISMA guidelines. App quality was assessed using the Mobile App Rating Scale (MARS). Apps providing blood alcohol calculators (hereafter “calculators”) were reviewed against current alcohol advice for accuracy. Results A total of 58 apps (30 iOS and 28 Android) met inclusion criteria and were included in the final analysis. Drink driving prevention apps had significantly lower engagement and overall quality scores than alcohol management apps. Most calculators provided conservative blood alcohol content (BAC) time until sober calculations. None of the apps had been evaluated to determine their efficacy in changing either drinking or driving behaviors. Conclusions This novel study demonstrates that most drink driving prevention apps are not engaging and lack accuracy. They could be improved by increasing engagement features, such as gamification. Further research should examine the context and motivations for using apps to prevent driving after drinking in at-risk populations. Development of drink driving prevention apps should incorporate evidence-based information and guidance, lacking in current apps. PMID:27502956

    Individuals who drink alcohol for the explicit motive of facilitating or enhancing sex may be more likely to engage in risky sexual behavior, including having sex under the influence of alcohol. However, efforts to assess sexual motives for drinking (SMDs) have been very limited to date. We examined the psychometric properties of a 5-item measure of SMDs in a sample of HIV-positive heavy drinking men who have sex with men. Findings provided excellent support for the scale's internal consistency and concurrent validity with a well-established measure of sexual alcohol expectancies (SAEs). Good discriminant validity was also established, as SMDs were correlated with other drinking motives but uniquely predicted the proportion of sex acts occurring under the influence of alcohol and other drugs, over and above other drinking motives and SAEs. SMDs were not significantly associated with unprotected anal intercourse. Adjusting for alcohol problem severity, higher SMDs were associated with lower willingness to consider changing drinking. Results suggest this measure of SMDs exhibits sound psychometric properties and may be useful in studies examining the association between alcohol use and sexual behavior. (PsycINFO Database Record

    2014-06-01

    Background: Energy drinks and energy shots are popular consumer beverages that are advertised to increase feelings of alertness. Typically, these products include high levels of caffeine, a mild psychostimulant drug. The scientific evidence demonstrating the specific benefits of energy products to users in terms of subjective state and objective performance is surprisingly lacking. Moreover, there are rising health concerns associated with the use of these products. Therefore, the purpose of this study was to investigate the acute effects of a popular energy shot (5-Hour Energy(®)) on subjective and objective measures that were assessed hourly for 6 hours following consumption. Methods: Participants (n=14) completed a three-session study where they received the energy shot, a placebo control, and no drink. Following dose administration, participants completed subjective Profile of Mood States ratings hourly for 6 hours. Participants also repeatedly completed a behavioral control task (the cued go/no-go task) and provided blood pressure and pulse rate readings at each hour. Results: Consumption of the energy shot did improve subjective state, as measured by increased ratings of vigor and decreased ratings of fatigue. However, the energy shot did not alter objective performance, which worsened over time. Importantly, the energy shot elevated both systolic and diastolic blood pressure. Conclusions: Consumption of one energy shot may only result in modest benefits to subjective state. Individuals with preexisting hypertension or other medical conditions should be cautious about using these new consumer products.

    Despite widespread interest in children's adjustment problems, existing research does not provide conclusive evidence regarding the direction of the associations of achievement with classroom attention problems and disruptive behavior over the course of elementary school. Using a nationally representative sample of 16,260 kindergarteners, this study examined the temporal sequence of achievement, classroom attention problems, and disruptive behavior, focusing on how changes in skills and problems unfold across key periods between kindergarten and fifth grade. Results indicate that improvements in attention during the earliest years of schooling predict achievement gains through third grade. However, changes in disruptive behavior do not predict subsequent changes in achievement. Evidence linking changes in achievement to changes in classroom attention problems and disruptive behavior was less consistent. These findings point to the need to develop and examine early interventions that can improve attention skills as a mechanism for improving children's academic trajectories in elementary school.

    In the Japanese quail, 7α-hydroxypregnenolone, a previously undescribed avian neurosteroid, is actively produced in the brain. 7α-Hydroxypregnenolone acts as a novel neuronal activator to stimulate locomotor activity of quail. Therefore, in this study, we determined whether 7α-hydroxypregnenolone changes the expression of sexual behavior in Japanese quail. We first measured diurnal changes in sexual behavior of male quail exposed to a long-day photoperiod. We found that sexual behavior of male quail was high in the morning when endogenous 7α-hydroxypregnenolone level is high. Subsequently, we centrally administered 7α-hydroxypregnenolone in the evening when endogenous 7α-hydroxypregnenolone level is low. In the 30 min after intracerebroventricular (ICV) injection, 7α-hydroxypregnenolone dose dependently increased the frequency of sexual behavior of male quail. However, 7β-hydroxypregnenolone, a stereoisomer of 7α-hydroxypregnenolone, did not effect on the frequency of sexual behavior of male quail. In addition, to confirm the action of 7α-hydroxypregnenolone on sexual behavior, male birds received an ICV injection of ketoconazole, an inhibitor of cytochrome P450s, and behavioral experiments were performed in the morning. Ketoconazole significantly decreased the frequency of sexual behavior of male quail, whereas administration of 7α-hydroxypregnenolone to ketoconazole-treated males increased the frequency of their sexual behavior. These results indicate that 7α-hydroxypregnenolone regulates diurnal changes in sexual behavior of male quail.

    This study evaluates associations between coping drinking motives (CDM; drinking to regulate negative affect), depressive symptoms, and drinking behavior and extends the literature by also taking into account gender differences. Two hundred forty-three college students (Mean age = 22.93, SD = 6.29, 82% female) participated. Based on previous research, we expected that CDM would be positively associated with drinking and problems, particularly among those higher in depressive symptoms, as individuals experiencing higher levels of negative affect (i.e. depressive symptoms) and who drink to cope are likely to drink more and experience more alcohol-related problems. Lastly, based on established gender differences, we expected that CDM would be positively associated with drinking and problems, especially among females higher in depressive symptoms. Unexpectedly, findings suggested that CDMs were positively related to peak drinking, especially among those lower in depressive symptoms. Results further revealed a significant three-way interaction between CDM, depressive symptoms, and gender when predicting alcohol-related problems and drinking frequency. Specifically, we found that CDM were more strongly associated with problems among women who were lower in depressive symptoms; whereas CDM were more strongly associated with problems among men who were higher in depressive symptoms. These findings offer a more comprehensive depiction of the relationship between depressive symptoms, CDM, and drinking behavior by taking into account the importance of gender differences. These results provide additional support for considering gender when designing and implementing alcohol intervention strategies. PMID:25525419

    1977-04-01

    This study presents a reanalysis of data from Rokeach's self-confrontation experiments using path analytic techniques. Contrary to Rokeach's interpretations, findings indicate that behavior changes following self-confrontation are not primarily mediated through changes in value priorities. Rather, the available data suggest that the self-confrontation process involves the resolution of inconsistencies between behaviors and self-conceptions that are revelaed during the treatment session. The authors interpret these findings within the framework of Rokeach's general theory of self-disatisfaction and cognitive-behavioral change. Suggestions for future directions in self-confrontation research are offered.

  15. Selective breeding for a behavioral trait changes digit ratio.

    Directory of Open Access Journals (Sweden)

    Reginia H Y Yan

    Full Text Available The ratio of the length of the second digit (index finger divided by the fourth digit (ring finger tends to be lower in men than in women. This 2D:4D digit ratio is often used as a proxy for prenatal androgen exposure in studies of human health and behavior. For example, 2D:4D ratio is lower (i.e. more "masculinized" in both men and women of greater physical fitness and/or sporting ability. Lab mice have also shown variation in 2D:4D as a function of uterine environment, and mouse digit ratios seem also to correlate with behavioral traits, including daily activity levels. Selective breeding for increased rates of voluntary exercise (wheel running in four lines of mice has caused correlated increases in aerobic exercise capacity, circulating corticosterone level, and predatory aggression. Here, we show that this selection regime has also increased 2D:4D. This apparent "feminization" in mice is opposite to the relationship seen between 2D:4D and physical fitness in human beings. The present results are difficult to reconcile with the notion that 2D:4D is an effective proxy for prenatal androgen exposure; instead, it may more accurately reflect effects of glucocorticoids, or other factors that regulate any of many genes.

    Objectives Examine energy drink/shot and regular and diet soft drink use among US secondary school students in 2010–2011, and associations between such use and substance use. Methods We used self-reported data from cross-sectional surveys of nationally representative samples of 8th, 10th, and 12th grade students and conducted multivariate analyses examining associations between beverage and substance use controlling for individual and school characteristics. Results Approximately 30% of students reported consuming energy drinks or shots; more than 40% reported daily regular soft drink use, and about 20% reported daily diet soft drink use. Beverage consumption was strongly and positively associated with past 30-day alcohol, cigarette, and illicit drug use. The observed associations between energy drinks and substance use were significantly stronger than those between regular or diet soft drinks and substance use. Conclusions This correlational study indicates that adolescent consumption of energy drinks/shots is wide-spread, and that energy drink users report heightened risk for substance use. This study does not establish causation between the behaviors. Education for parents and prevention efforts among adolescents should include education on the masking effects of caffeine in energy drinks on alcohol- and other substance-related impairments, and recognition that some groups (such as high sensation-seeking youth) may be particularly likely to consume energy drinks and to be substance users.

    Climate change engagement requires individuals to understand an abstract and complex topic and realize the profound implications of climate change for their families and local community. In recent years federal agencies have spent millions of dollars on climate change education to prepare a nation for a warming future. The majority of these education efforts are based on a knowledge deficit model. In this view 'educate' means 'provide information'. However cognitive and behavioral research and current action demonstrate that information alone is not enough; knowledge does not necessarily lead to action. Educators are speaking to deaf ears if we rely on passive and abstract information transfer and neglect more persuasive and affective approaches to communication. When climate change is presented abstractly as something that happens in the future to people, environments, animals somewhere else it is easy to discount. People employ two separate systems for information processing: analytical-rational and intuitive-experiential Authentic local research experiences that engage both analytical and experiential information processing systems not only help individuals understand the abstraction of climate change in a concrete and personally experienced manner, but are more likely to influence behavior. Two on-line, graduate-level courses offered within University of Nebraska's Masters of Applied Science program provide opportunities for participants to engage in authentic inquiry based studies climate change's local impacts, and work with K-12 learners in promoting the scientific awareness and behavioral changes that mitigate against the negative impacts of a changing climate. The courses are specifically designed to improve middle and high school (grades 6-12) teachers' content knowledge of climate processes and climate change science in the context of their own community. Both courses provide data-rich, investigative science experiences in a distributed digital

    More and more children do not grow up in traditional nuclear families. Instead they grow up in single parent  households or in families with a step-parent. For example, in 1980, almost 83% of all Danish children in the ages 0 to 17 lived with both of their parents, but this number steadily...... structure changes during childhood. More family structure changes implies worse outcomes and might actually be more important than the number of years a child has spent in a single parent household. The age at which the family structure change occurs also seems to be important at least for some outcomes....... decreased to 73% in 2005. Hence it is important to improve our understanding of the impact of "shocks" in family structure due to parental relationship dissolution on children.

    Radin, Sandra M; Neighbors, Clayton; Walker, Patricia Silk; Walker, R Dale; Marlatt, G Alan; Larimer, Mary

    2006-06-01

    This study explored the changing relations among self-worth, peer deviance, and alcohol-related problems in a sample of 224 urban-dwelling, American Indian adolescents. Data were collected annually at 7 time points to test a proposed mediational model. As expected, peer deviance mediated the relation between low self-worth and alcohol-related problems in younger adolescents; however, this relation did not hold as participants became older. In older adolescents, low self-worth and peer deviance directly and independently contributed to alcohol problems. Possible explanations for and implications of these findings are discussed in terms of developmental changes during adolescence.

    The current study investigated the relations among therapist adherence to an evidence-based treatment for youth with serious antisocial behavior (i.e., Multisystemic Therapy), organizational climate and structure, and improvement in youth behavior problems one-year post treatment. Participants were 1979 youth and families treated by 429 therapists across 45 provider organizations in North America. Hierarchical Linear Modeling (HLM) results showed therapist adherence predicted improvement in youth behavior. Two structure variables and one climate variable predicted changes in youth behavior, and the climate variable also predicted therapist adherence. No statistical support for formal mediation of organizational effects through adherence was found, though examination of changes in parameter estimates suggest a possible interplay of organizational climate with adherence and youth behavior change.

  8. Harnessing social media for health promotion and behavior change.

    Science.gov (United States)

    Korda, Holly; Itani, Zena

    2013-01-01

    Rapid and innovative advances in participative Internet communications, referred to as "social media," offer opportunities for modifying health behavior. Social media let users choose to be either anonymous or identified. People of all demographics are adopting these technologies whether on their computers or through mobile devices, and they are increasingly using these social media for health-related issues. Although social media have considerable potential as tools for health promotion and education, these media, like traditional health promotion media, require careful application and may not always achieve their desired outcomes. This article summarizes current evidence and understanding of using social media for health promotion. More important, it discusses the need for evaluating the effectiveness of various forms of social media and incorporating outcomes research and theory in the design of health promotion programs for social media.

    2011-01-01

    Epiphytic filamentous algae (EFA) were noted as a serious problem to reduce the production and quality of K. alvarezii. The morphological studies revealed that the main epiphyte on K. alvarezii was Neosiphonia savatieri in China. Though the harmful effects of EFA on the production of K. alvarezii have been reported, the detailed mechanism of the N. savatieri in limiting the production of K. alvarezii has not been studied yet. The present paper studied the effects of N. savatieri infection on photosynthetic behaviors in K. alvarezii by detecting chlorophyll fluorescence transient in vivo. The results revealed that damage of oxygen-evolving complex (OEC), decrease of active reaction centers (RCs), and the plastoquinone (PQ) pool as well as significant reduction in the performance indexes (PI) of PSII were caused by the infection of N. savatieri. The influence of N. savatieri on photosynthetic activity of K. alvarezii should be one of the important reasons to reduce the production of K. alvarezii infected by N. savatieri.

  12. Player Experiences and Behaviors in a Multiplayer Game: designing game rules to change interdependent behavior

    Directory of Open Access Journals (Sweden)

    Niko Vegt

    2016-12-01

    Full Text Available Serious gaming is used as a means for improving organizational teamwork, yet little is known about the effect of individual game elements constituting serious games. This paper presents a game design experiment aimed at generating knowledge on designing game elements for teamwork. In previous work, we suggested that interaction- and goal-driven rules could guide interdependence and teamwork strategies. Based on this finding, for the present experiment we developed two versions of multiplayer Breakout, varying in rule-sets, designed to elicit player strategies of either dependent competition or dependent cooperation. Results showed that the two rule-sets could generate distinct reported player experiences and observable distinct player behaviors that could be further discriminated into four patterns: expected patterns of helping and ignoring, and unexpected patterns of agreeing and obstructing. Classic game theory was applied to understand the four behavior patterns and made us conclude that goal-driven rules steered players towards competition and cooperation. Interaction rules, in contrast, mainly stimulated dependent competitive behavior, e.g. obstructing each other. Since different types of rules thus led to different player behavior, discriminating in game design between interaction- and goal-driven rules seems relevant. Moreover, our research showed that game theory proved to be useful for understanding goal-driven rules.

    Aal-Aaboda, Munaf; Alhaddad, Hasan; Osowik, Francis; Nauli, Surya M; Sari, Youssef

    2015-06-01

    Alcohol consumption is largely associated with alterations in the extracellular glutamate concentrations in several brain reward regions. We recently showed that glutamate transporter 1 (GLT-1) is downregulated following chronic exposure to ethanol for 5 weeks in alcohol-preferring (P) rats and that upregulation of the GLT-1 levels in nucleus accumbens and prefrontal cortex results, in part, in attenuating ethanol consumption. Cystine glutamate antiporter (xCT) is also downregulated after chronic ethanol exposure in P rats, and its upregulation could be valuable in attenuating ethanol drinking. This study examines the effect of a synthetic compound, (R)-(-)-5-methyl-1-nicotinoyl-2-pyrazoline (MS-153), on ethanol drinking and expressions of GLT-1 and xCT in the amygdala and the hippocampus of P rats. P rats were exposed to continuous free-choice access to water, 15% and 30% ethanol, and food for 5 weeks, after which they received treatments of MS-153 or vehicle for 5 days. The results show that MS-153 treatment significantly reduces ethanol consumption. It was revealed that GLT-1 and xCT expressions were downregulated in both the amygdala and the hippocampus of ethanol-vehicle-treated rats (ethanol-vehicle group) compared with water-control animals. MS-153 treatment upregulated GLT-1 and xCT expressions in these brain regions. These findings demonstrate an important role for MS-153 in these glutamate transporters for the attenuation of ethanol-drinking behavior.

    2015-05-01

    The overweight and obesity trends have risen over the past few decades, placing significant burdens on health care in terms of increased morbidity and cost. Behavioral change therapy is an effective treatment strategy and includes goal setting, self-monitoring, problem solving, and reinforcement tactics. Traditionally, behavior change therapy has been delivered using face-to-face counseling along with paper and pen recording of dietary intake and physical activity. The current advances in technology provide opportunities to deliver interventions using cellphones, internet, and active video games. These new methods to deliver behavior change for the management and prevention of obesity are being developed in order to increase access, improve convenience, decrease cost, and increase participant engagement. In this review, we present new approaches to promote behavior changes in the management of obesity. Currently available data show promising results. However, future research is needed to address study limitations and implementation challenges of these innovative interventions.

  1. The equal right to drink.

    Schmidt, Laura A

    2014-11-01

    The starting place for this essay is Knupfer and Room's insight that more restrictive norms around drinking and intoxication tend to be selectively applied to the economically dependent segments of society, such as women. However, since these authors wrote in 1964, women in the US and many other societies around the globe have experienced rising economic independence. The essay considers how the moral categories of acceptable drinking and drunkenness may have shifted alongside women's rising economic independence, and looks at evidence on the potential consequences for women's health and wellbeing. I argue that, as women have gained economic independence, changes in drinking norms have produced two different kinds of negative unintended consequences for women at high and low extremes of economic spectrum. As liberated women of the middle and upper classes have become more economically equal to men, they have enjoyed the right to drink with less restraint. For them, alongside the equal right to drink has come greater equality in exposure to alcohol-attributable harms, abuse and dependence. I further suggest that, as societies become more liberated, the economic dependency of low-income women is brought into greater question. Under such conditions, women in poverty-particularly those economically dependent on the state, such as welfare mothers-have become subject to more restrictive norms around drinking and intoxication, and more punitive social controls.

  4. Influence from friends to drink more or drink less: a cross-national comparison.

    Drinking habits are socially patterned and social networks influence individuals' drinking behaviors. Previous studies have focused primarily upon the influence from family members to drink less. Those studies that have focused upon peer influence have been largely confined to social norms among adolescent and college-age drinkers. By contrast, based in adult populations, this article examines exhortations from friends not only to reduce alcohol consumption but also to increase it. Survey data in 15 countries that participate in the Gender, Alcohol and Culture: An International Study project (GENACIS) were used to test whether there were country and gender differences concerning the influence to drink less or to drink more by friends and examine if this was affected by the drinking behavior. The findings revealed that those influenced to drink less had more heavy episodic drinking (HED) occasions than those who did not report such influence. By contrast, influence to drink more, originating mainly from same-sex friends, may be more the result of social situations that encourage all drinkers, regardless of their frequency of HED occasions. At the country level, influence to drink less for both sexes decreased with the proportion of drinkers in a country. Similarly, influence to drink less for both sexes also decreased in countries where gender roles were more egalitarian. Thus, in countries where alcohol use is more widespread and fewer differences are observed between male and female gender role expectations, fewer people were influenced to drink less. These findings have implications for social and behavioral strategies designed to reduce alcohol-related harm across a wide range of cultures.

    This study aimed to evaluate enamel surface roughness (Ra) and pH before and after erosion by soft drinks. Enamel was exposed to a soft drink (cola, orange juice or green tea) for 1, 5 or 60 min; Ra was measured using contact-stylus surface profilometry (SSP) and non-contact focus variation 3D microscope (FVM). Surface pH was measured using a micro pH sensor. Data were analyzed at significance level of alpha=0.05. There was a significant correlation in Ra between SSP and FVM. FVM images showed no changes in the surface morphology after various periods of exposure to green tea. Unlike cola and orange juice, exposure to green tea did not significantly affect Ra or pH. A significant correlation was observed between surface pH and Ra change after exposure to the drinks. Optical surface analysis and micro pH sensor may be useful tools for non-damaging, quantitative assessment of soft drinks erosion on enamel.

    Obesity prevalence is increasing all over the world. Most affected are people changing from a traditional lifestyle to an environment with both availability of high energy diet and less physical activity. Glycemic index (GI) is a measure of dietary glycemic carbohydrates, representing their ability to raise blood glucose concentrations. It refers to the postprandial blood glucose response expressed as a percentage of the response to a reference food (glucose or white bread) containing the same carbohydrate content. Given the present high consumption of sugary drinks, the putative contribution of these products to obesity deserves investigation. The aim of this study was to determine the GI of some drinks from the Portuguese market. Postprandial glycemia after ingestion of apple Frutis, peach Frutis, Green tea Frutea, green tea, black tea, lupin infusion, rooibos infusion, raftilose solution or bran solution has been determined for two hours in a caucasian population of young adults of any sex, 17 to 24 years of age. Apple Frutis GI was found to be 54.3, i.e., a low GI; Frutea Green tea had a GI of 64.7, considered as a moderate GI; peach Frutis showed a high GI, 86.6. Green and Black teas as well as rooibos and lupin infusions, all with added glucose (25 g), did not change glycemic response in comparison with the reference solution (water with 25 g glucose). No differences were seen after raftilose and bran solutions by comparison with the reference solution. GI information may help the choice of carbohydrates to include in a healthy diet. Formerly considered as a parameter of interest to diabetic patients, it may actually interest anybody concerned with a healthy diet. This study has been performed by medical and nutritional science students, who observed glycemic excursions in themselves, after drink ingestion. This experiment allowed them to see the impressive rise of glycemia after ingestion of a sugary drink, by comparison with basal levels which would not

  10. Mind wandering via mental contrasting as a tool for behavior change.

    2013-09-02

    When people engage in mind wandering they drift away from a task toward their inner thoughts and feelings. These thoughts often circle around people's personal futures. One assumed function of mind wandering is that it aids problem solving and planning for the future. We will discuss different forms of mind wandering and their effects on problem solving and behavior change. While solely fantasizing about a desired future leads to poor problem solving and little behavior change, mind wandering in the form of mental contrasting leads to skilled problem solving and substantial behavior change. In mental contrasting, people first envision the desired future and then imagine the obstacles that need to be surmounted to reach said future. Mental contrasting instigates behavior change by modulating the strength of associations between future and reality and between reality and instrumental action. Intervention research shows that mental contrasting can be taught as a cost- and time-effective self-regulation strategy of behavior change. The findings have implications for research on mind wandering, problem solving, and on creating effective interventions of behavior change.

  13. RUSSIAN DRINKING: TOO LATE FOR EMERGENCY MEASURES

    Directory of Open Access Journals (Sweden)

    Alexander Evgenjevich Kuznetsov

    2015-01-01

    Full Text Available Russian drinking for the first time demonstrates weakening of specialization in spirits drinking and stabilization of amount drunk. This suggests expectations of drinking qualitative turn, i.e. to consumer’s choice oriented to quality of drinking rather than to quantity, and further to lessening the drinking norm. Experience of wine-drinking countries of Europe and influence of pan-European homogenization of patterns of drinking, favor such a perspective. The marked decrease of drinking norm in wine-drinking countries was achieved with the minimal state intervention. Survey data (n=904 is provided to corroborate the claim that Russian drinking is able to self-regulate. The data witness weak support for government’s measures taken to restrict access to beverages sale in terms of age, time, place, and price; customers are likely to value freedom of choice unbridled. Governmental pursuance of simplistic access-and-pricing restrictive policies recently undertaken, may force Russian drinking back to another cycle of alcoholisation within the old ‘northern’ model. Bootlegging expansion, formerly progressive specialization in spirits drinking, habit of making gross purchases in population are explained by former experiences of coping with deficits, dry campaigns, and traditional culture of religious and secular abstinences. Scarcity of modes of compensatory behaviors and low concern for health also back up the special cultural status of alcohol. Government should seek for positive measures, viz. wider sporting involvement for students and inclusion for disabled to revive the nation’s regard for health and awareness of health-related risks.

    This study investigates morphological and biochemistry effects of binge ethanol consumption in parotid (PG) and submandibular (SG) salivary glands of rats from adolescence to adulthood. Female Wistar rats (n = 26) received ethanol at 3 g/kg/day (20% w/v) for 3 consecutive days/week from the 35th until the 62nd day of life. Animals were treated in two periods: 1 week (G1) and 4 weeks (G2), with a control (treated with distilled water) and an ethanol group to each period. In morphological analysis, morphometric and immunohistochemistry evaluation for smooth muscle actin (αSMA), cytokeratin-18 (CK-18), and vimentin (VIM) were made. Biochemical changes were analyzed by concentration of nitrites and levels of malondialdehyde (MDA). The difference between groups in each analysis was evaluated by Mann-Whitney U test or Student's t-test (p ≤ 0.05). PG showed, at one week of ethanol exposure, lower CK-18 and α-SMA expression, as well as MDA levels. After four weeks, lower CK-18 and higher MDA levels were observed in PG exposed to ethanol, in comparison to control group. SG showed lower α-SMA expression after 1 and 4 weeks of ethanol exposure as well as higher MDA levels after 1 week. Ethanol binge consumption during adolescence promotes tissue and biochemical changes with only one-week binge in acinar and myoepithelial PG cells. PMID:27579155

    This study aimed to evaluate the effect of sepsis on behavioral changes on the ketamine-induced animal model of schizophrenia. Male Wistar rats underwent Cecal Ligation and Perporation (CLP) with "basic support" or were sham-operated. After 30 days, the animals were submitted to a model of schizophrenia by injection of Ketamine. The behavior tests were performed after 30 min of the injection of Ketamine or saline. Ketamine in doses of 15 and 25mg/kg increased locomotor activity, latency to first contact in the social interaction and stereotyped behavior. Some changes caused by sepsis may be associated with a predisposition to develop schizophrenia in the animal model.

    2014-06-01

    The municipalities of Guadalajara and Zapopan, Jalisco State, Mexico, have participated in efforts to reduce road traffic injuries. They have participated actively in the Mexican Road Safety Initiative since 2008. As a result, in September 2010 they passed laws to reduce the legal alcohol levels for driving motor vehicles. To assess the short-term impact of these measures on rates and severity of alcohol-related collisions and injuries, we conducted a secondary analysis of official databases on mortality, morbidity, and collisions. We performed a time-series analysis to assess the trend. Significant changes were observed in the monthly proportion of alcohol-related deaths and collision rates following these interventions. The article concludes with recommendations to improve the reform's enforcement and results.

    2012-07-01

    Serious video games for health are designed to entertain while changing a specific health behavior. This article identifies behavioral principles that can guide the development of serious video games focused on changing a variety of health behaviors, including those attempting to decrease risk of obesity and type 2 diabetes. Guidelines discussed include how to develop video games that provide a solid foundation for behavior change by enhancing a player's knowledge and skill, ways in which personal mastery experiences can be incorporated into a video game environment, using game characters and avatars to promote observational learning, creating personalized experiences through tailoring, and the importance of achieving a balance between "fun-ness" and "seriousness." The article concludes with suggestions for future research needed to inform this rapidly growing field.

    2012-07-01

    Previous work suggests but cannot prove that education improves health behaviors. We exploit a randomized intervention that increased schooling (and reduced working) among male students in the Dominican Republic, by providing information on the returns to schooling. We find that treated youths were much less likely to smoke at age 18 and had delayed onset of daily or regular drinking. The effects appear to be due to changes in peer networks and disposable income. We find no evidence of a direct impact of schooling on rates of time preference, attitudes towards risk or perceptions that drinking or smoking are harmful to health, though our measures of these factors are more limited.

    2012-04-01

    The current study examined whether the relationship between drinking motives and alcohol-related outcomes was mediated by college adjustment. Participants (N=253) completed an online survey that assessed drinking motives, degree of both positive and negative college adjustment, typical weekly drinking, and past month negative alcohol-related consequences. Structural equation modeling examined negative alcohol consequences as a function of college adjustment, drinking motives, and weekly drinking behavior in college students. Negative college adjustment mediated the relationship between coping drinking motives and drinking consequences. Positive college adjustment was not related to alcohol consumption or consequences. Positive reinforcement drinking motives (i.e. social and enhancement) not only directly predicted consequences, but were partially mediated by weekly drinking and degree of negative college adjustment. Gender specific models revealed that males exhibited more variability in drinking and their positive reinforcement drinking motives were more strongly associated with weekly drinking. Uniquely for females, coping motives were directly and indirectly (via negative adjustment) related to consequences. These findings suggest that interventions which seek to decrease alcohol-related risk may wish to incorporate discussions about strategies for decreasing stress and increasing other factors associated with better college adjustment.

    This study investigated conditions under which family structure matters most for child well-being. Using data from the Children of the National Longitudinal Survey of Youth (n = 3,936), a national sample of U.S. families, it was estimated how changes in family structure related to changes in children's behavior between age 3 and 12 separately by household income level to determine whether associations depended on families' resources. Early changes in family structure, particularly from a two-biological-parent to single-parent family, predicted increases in behavior problems more than later changes, and movements into single and stepparent families mattered more for children of higher versus lower income parents. Results suggest that for children of higher income parents, moving into a stepfamily may improve, not undermine, behavior.

  5. Advanced Behavioral Analyses Show that the Presence of Food Causes Subtle Changes in C. elegans Movement.

    2016-01-01

    As a widely used and studied model organism, Caenorhabditis elegans worms offer the ability to investigate implications of behavioral change. Although, investigation of C. elegans behavioral traits has been shown, analysis is often narrowed down to measurements based off a single point, and thus cannot pick up on subtle behavioral and morphological changes. In the present study videos were captured of four different C. elegans strains grown in liquid cultures and transferred to NGM-agar plates with an E. coli lawn or with no lawn. Using an advanced software, WormLab, the full skeleton and outline of worms were tracked to determine whether the presence of food affects behavioral traits. In all seven investigated parameters, statistically significant differences were found in worm behavior between those moving on NGM-agar plates with an E. coli lawn and NGM-agar plates with no lawn. Furthermore, multiple test groups showed differences in interaction between variables as the parameters that significantly correlated statistically with speed of locomotion varied. In the present study, we demonstrate the validity of a model to analyze C. elegans behavior beyond simple speed of locomotion. The need to account for a nested design while performing statistical analyses in similar studies is also demonstrated. With extended analyses, C. elegans behavioral change can be investigated with greater sensitivity, which could have wide utility in fields such as, but not limited to, toxicology, drug discovery, and RNAi screening.

    2015-12-01

    A typical goal of voice therapy is a behavioral change in the patient's everyday speech. The SLP's plan for voice therapy should therefore optimally include strategies for automatization. The aim of the present study was to identify and describe factors that promote behavioral learning and habit change in voice behavior and have the potential to affect patient compliance and thus therapy outcome. Research literature from the areas of motor and behavioral learning, habit formation, and habit change was consulted. Also, specific elements from personal experience of clinical voice therapy are described and discussed from a learning theory perspective. Nine factors that seem to be relevant to facilitate behavioral learning and habit change in voice therapy are presented, together with related practical strategies and theoretical underpinnings. These are: 1) Cue-altering; 2) Attention exercises; 3) Repetition; 4) Cognitive activation; 5) Negative practice; 6) Inhibition through interruption; 7) Decomposing complex behavior; 8) The 'each time-every time' principle; and 9) Successive implementation of automaticity.

    2008-01-01

    Social marketing uses commercial marketing strategies to change individual and organizational behavior and policies. It has been effective on a population level across a wide range of public health and health care domains. There is limited evidence of the effectiveness of social marketing in changing health care consumer behavior through its impact on patient-provider interaction or provider behavior. Social marketers need to identify translatable strategies (e.g., competition analysis, branding, and tailored messages) that can be applied to health care provider and consumer behavior. Three case studies from social marketing illustrate potential strategies to change provider and consumer behavior. Countermarketing is a rapidly growing social marketing strategy that has been effective in tobacco control and may be effective in countering pharmaceutical marketing using specific message strategies. Informed decision making is a useful strategy when there is medical uncertainty, such as in prostate cancer screening and treatment. Pharmaceutical industry marketing practices offer valuable lessons for developing competing messages to reach providers and consumers. Social marketing is an effective population-based behavior change strategy that can be applied in individual clinical settings and as a complement to reinforce messages communicated on a population level. There is a need for more research on message strategies that work in health care and population-level effectiveness studies.

    The purpose of this research was to investigate variables relevant to smoking cessation early in the process of change through an application of the Theory of Planned Behavior [Ajzen, I. (1985). From intentions to actions: A theory of planned behavior. In J. Kuhl and J. Beckman (Eds). Action-control: From cognition to behavior (pp.11-39). Heidelberg: Springer.] to the temporal structure provided by the Transtheoretical Model. Study 1 was a preliminary elicitation study (n=68) conducted to ground the concepts used in the model testing in Study 2 [Ajzen, I., Fishbein, M. (1980). Understanding attitudes and predicting social behavior, Englewood Cliffs, NJ: Prentice-Hall.]. Study 2 tested the proposed model fit with data from a sample of 230 adult smokers. Structural equation modeling did not support the Theory of Planned Behavior as a model of motivation for progress through the stages of change and highlighted measurement issues with perceived behavioral control. A modified model using the Theory of Reasoned Action provided a good fit to the data, accounting for approximately 64% of the variance in intention to quit smoking and stage of change. This research addresses the need for a more complete theoretical rationale for progress through stages of change.

    Full Text Available Background: Although various medical and psychological interventions have been used to treat addiction, addiction particularly methamphetamine addiction as a social, health and medical issues is still jeopardizing the human community. This study is aimed at determining the impact of teaching life skills and changing behavior on the emotional well-being of the individuals addicted to crystal methamphetamine. Materials and Methods: This study was carried out using before-after plan with participation of 28 crystal methamphetamine addicts. In addition to receiving medical treatment, the intervention group patients obtained necessary trainings required for developing life skill and changing behavior during 15 sessions, whilst the control group received only the routine pharmacotherapy treatments and primary interventions. Then pretest and posttest scores of the two groups were compared. Results: The mean score on emotional well-being by the intervention group is lower than that in control group after treatment (10.71<18.78 which was statistically significant. The history of dependence on methamphetamine, age, education, the times of quits, and the marital status had no impact on the extent of the influence of teaching life skills and behavior changes on the individuals’ emotional well-being. Conclusion: Notwithstanding that addiction could influence various aspects of mental and emotional health of dependent people, teaching life skills and behavioral changes may lead to enhancement in their emotional well-being. Hence it is necessary to encourage these individuals to participate in group sessions of changing behavior and teaching life skills.

    Serious video games (VG) offer new opportunities for promoting health related diet and physical activity change among children. Games can be designed to use storylines, characters, and behavior change procedures, including modeling (e.g., engaging characters make changes themselves, and face and overcome challenges related to fruit and vegetable (FV) and physical activity (PA) goal attainment and/or consumption), skill development (e.g., asking behaviors; virtual recipe preparation), self regulatory behaviors (problem solving, goal setting, goal review, decision making), rewards (e.g., points and positive statements generated by the program), immediate feedback (e.g., through characters and/or statements that appear on the computer screen at critical decision points), and personalization (e.g., tailored choices offered at critical junctures, based on responses to baselines questions related to preferences, outcome expectancies, etc). We are in the earliest stages of learning how to optimally design effective behavior change procedures for use in VG, and yet they have been demonstrated to change behavior. As we learn, VG offer more and better opportunities for obesity prevention that can adjust to individual needs and preferences.

    As part of a larger randomized controlled trial, 188 participants were randomized to behavior therapy (BT), cognitive therapy (CT), or cognitive-behavioral therapy (CBT) for insomnia. The aims of this study were threefold: (a) to determine whether change in dysfunctional beliefs about sleep was related to change in sleep, insomnia symptoms, and impairment following treatment; (b) to determine whether BT, CT, and CBT differ in their effects on dysfunctional beliefs; and (c) to determine whether the treatments differ in their effects on particular kinds of dysfunctional beliefs. Beliefs, sleep, insomnia symptoms, and sleep-related psychosocial impairment were assessed at pretreatment, posttreatment, and 6- and 12-month follow-up. Greater change in dysfunctional beliefs occurring over the course of BT, CT, or CBT was associated with greater improvement in insomnia symptoms and impairment at posttreatment and both follow-ups. All groups experienced a significant decrease in dysfunctional beliefs during treatment, which were sustained through 6- and 12-month follow-up. Compared with the BT group, a greater proportion of participants in the CT and/or CBT groups endorsed dysfunctional beliefs below a level considered clinically significant at posttreatment and 12-month follow-up. The results demonstrate the importance of targeting dysfunctional beliefs in insomnia treatment, suggest that beliefs may be significantly modified with BT alone, and indicate that cognitive interventions may be particularly powerful in enhancing belief change.

    2016-01-01

    Background Globally, mobile phones have achieved wide reach at an unprecedented rate, and mobile phone apps have become increasingly prevalent among users. The number of health-related apps that were published on the two leading platforms (iOS and Android) reached more than 100,000 in 2014. However, there is a lack of synthesized evidence regarding the effectiveness of mobile phone apps in changing people’s health-related behaviors. Objective The aim was to examine the effectiveness of mobile phone apps in achieving health-related behavior change in a broader range of interventions and the quality of the reported studies. Methods We conducted a comprehensive bibliographic search of articles on health behavior change using mobile phone apps in peer-reviewed journals published between January 1, 2010 and June 1, 2015. Databases searched included Medline, PreMedline, PsycINFO, Embase, Health Technology Assessment, Education Resource Information Center (ERIC), and Cumulative Index to Nursing and Allied Health Literature (CINAHL). Articles published in the Journal of Medical Internet Research during that same period were hand-searched on the journal’s website. Behavior change mechanisms were coded and analyzed. The quality of each included study was assessed by the Cochrane Risk of Bias Assessment Tool. Results A total of 23 articles met the inclusion criteria, arranged under 11 themes according to their target behaviors. All studies were conducted in high-income countries. Of these, 17 studies reported statistically significant effects in the direction of targeted behavior change; 19 studies included in this analysis had a 65% or greater retention rate in the intervention group (range 60%-100%); 6 studies reported using behavior change theories with the theory of planned behavior being the most commonly used (in 3 studies). Self-monitoring was the most common behavior change technique applied (in 12 studies). The studies suggest that some features improve the

    Although most people understand the threat of climate change, they do little to modify their own energy conservation behavior. One reason for this gap between belief and behavior may be that individual actions seem unimpactful and therefore are not morally relevant. This research investigates how climate change helplessness-belief that one's actions cannot affect climate change-can undermine the moralization of climate change and personal energy conservation. In Study 1, climate change efficacy predicted both moralization of energy use and energy conservation intentions beyond individual belief in climate change. In Studies 2 and 3, participants read information about climate change that varied in efficacy message, that is, whether individual actions (e.g., using less water, turning down heat) make a difference in the environment. Participants who read that their behavior made no meaningful impact reported weaker moralization and intentions (Study 2), and reported more energy consumption 1 week later (Study 3). Moreover, effects on intentions and actions were mediated by changes in moralization. We discuss ways to improve climate change messages to foster environmental efficacy and moralization of personal energy use. (PsycINFO Database Record

    Insect behaviors are often influenced by light conditions including photoperiod, light intensity, and wavelength. Understanding pest insect responses to changing light conditions may help with developing alternative strategies for pest control. Little is known about the behavioral responses of leafhoppers (Hemiptera: Cicadellidae) to light conditions. The behavior of the tea green leafhopper, Empoasca onukii Matsuda, was examined when exposed to different light photoperiods or wavelengths. Observations included the frequency of locomotion and cleaning activities, and the duration of time spent searching. The results suggested that under normal photoperiod both female and male adults were generally more active in darkness (i.e., at night) than in light. In continuous darkness (DD), the locomotion and cleaning events in Period 1 (7:00–19:00) were significantly increased, when compared to the leafhoppers under normal photoperiod (LD). Leafhoppers, especially females, changed their behavioral patterns to a two day cycle under DD. Under continuous illumination (continuous quartz lamp light, yellow light at night, and green light at night), the activities of locomotion, cleaning, and searching were significantly suppressed during the night (19:00–7:00) and locomotion activities of both females and males were significantly increased during the day (7:00–19:00), suggesting a shift in circadian rhythm. Our work suggests that changes in light conditions, including photoperiod and wavelength, can influence behavioral activities of leafhoppers, potentially affecting other life history traits such as reproduction and development, and may serve as a method for leafhopper behavioral control.

    Most individuals engage in multiple unhealthy lifestyle behaviors with the potential for negative health consequences. Yet most health promotion research has addressed risk factors as categorically separate entities, and little is known about how to effectively promote multiple health behavior change (MHBC). This review summarizes the recent literature (January 2004 to December 2009) on randomized clinical trials evaluating MHBC interventions for primary prevention. Combining all the studies across all the reviews, fewer than 150 studies were identified. This is a fraction of the number of trials conducted on changing individual behavioral risks. Three primary behavioral clusters dominated: (1) the energy balance behaviors of physical activity and diet; (2) addictive behaviors like smoking and other drugs; and (3) disease-related behaviors, specifically cardiovascular disease (CVD) and cancer related. Findings were largely disappointing for studies of diet and physical activity, particularly with youth. Treating 2 addictions, including smoking, resulted in greater long-term sobriety from alcohol and illicit drugs. MHBC intervention effects were stronger and more consistent for cancer prevention than CVD prevention. MHBC interventions offer a new paradigm for broader, more comprehensive health promotion; however, the potential value in maximizing intervention impact is largely unmet.

    We investigated whether pretreatment with the neuropeptide cholecystokinin-8 affected methamphetamine (METH)-induced behavioral changes and dopaminergic neurodegeneration in male C57/BL6 mice. CCK-8 pretreatment alone had no effect on locomotion and stereotypic behavior and could not induce behavioral sensitization; however, it attenuated, in a dose-dependent manner, hyperlocomotion and behavioral sensitization induced by a low dose of METH (1mg/kg). CCK-8 attenuated METH-induced stereotypic behavior at a dose of 3mg/kg but not at 10mg/kg. CCK-8 pretreatment attenuated METH (10mg/kg)-induced hyperthermia, the decrease of tyrosine hydroxylase (TH) and dopamine transporter (DAT) in the striatum, and TH in the substantia nigra. CCK-8 alone had no effect on rectal temperature, TH and DAT expression in the nigrostriatal region. In conclusion, our study demonstrated that pretreatment with CCK-8 inhibited changes typically induced by repeated exposure to METH, such as hyperlocomotion, behavioral sensitization, stereotypic behavior, and dopaminergic neurotoxicity. These findings make CCK-8 a potential therapeutic agent for the treatment of multiple symptoms associated with METH abuse.

    This article describes a new theoretical approach to health promotion and behavior change that may be especially suited to underserved women. Appreciative inquiry (AI), an organizational development process that focuses on the positive and creative as a force for an improved future, is described and adapted for use as an intervention to achieve health behavior change at the individual level. Guiding principles for its use with clients are provided, and an example of its application is illustrated in a hypothetical case study of an African American woman of low-socioeconomic resources who is attempting to increase lifestyle exercise following a cardiac event. AI is contrasted with the more traditional problem-solving approaches to the provision of care. The advantages, challenges, and issues associated with the use of AI as a health behavior change strategy are discussed.

    Full Text Available The selection and configuration of building materials for optimal energy efficiency in a building require some assumptions and models for the thermal behavior of the utilized materials. Although the models for many materials can be considered acceptable for simulation and calculation purposes, the work for modeling the real time behavior of phase change materials is still under development. The data given in this article shows the thermal behavior of a flat roof element with a phase change material (PCM layer. The temperature and energy given to and taken from the building element are reported. In addition the solid–liquid behavior of the PCM is tracked through images. The resulting thermal behavior of the phase change material is discussed and simulated in [1] A. Tokuç, T. Başaran, S.C.

    Subtle cognitive and behavioral changes are common in early Parkinson’s disease. The cause of these symptoms is probably multifactorial but may in part be related to extra-striatal dopamine levels. 6-[18F]-Fluoro-L-dopa (FDOPA) positron emission tomography has been widely used to quantify dopamine metabolism in the brain; the most frequently measured kinetic parameter is the tissue uptake rate constant, Ki. However, estimates of dopamine turnover, which also account for the small rate of FDOPA loss from areas of specific trapping, may be more sensitive than Ki for early disease-related changes in dopamine biosynthesis. The purpose of the present study was to compare effective distribution volume ratio (eDVR), a metric for dopamine turnover, to cognitive and behavioral measures in Parkinson’s patients. We chose to focus the investigation on anterior cingulate cortex, which shows highest FDOPA uptake within frontal regions and has known roles in executive function. 15 Non-demented early-stage PD patients were pretreated with carbidopa and tolcapone, a central catechol-O-methyl transferase (COMT) inhibitor and then underwent extended imaging with FDOPA PET. Anterior cingulate eDVR was compared with composite scores for language, memory, and executive function measured by neuropsychological testing, and behavior change measured using two informant-based questionnaires, the Cambridge Behavioral Inventory and the Behavior Rating Inventory of Executive Function- Adult Version. Lower mean eDVR (thus higher dopamine turnover) in anterior cingulate cortex was related to lower (more impaired) behavior scores. We conclude that subtle changes in anterior cingulate dopamine metabolism may contribute to dysexecutive behaviors in Parkinson’s disease. PMID:25511521

    Behavior change by persuasive communications in a social dilemma, in which a university tried to persuade students to park their motorcycles in a designated lot in order to resolve noise problems, was studied by a questionnaire. Hayashi's quantification theory III was applied to variables such as subjective norms, beliefs in the effectiveness of one's cooperation, the perception of campus traffic conditions and attitudes toward one's parking behavior. Factor scores obtained were subjected to a cluster analysis, which, within 105 defectors, yielded three subgroups. Contrary to prediction, subgroups were not different in their cooperation ratio examined 10 months later, but tended to be different in their readiness for acceptance of persuasion and in their intention to cooperate in a social dilemma other than parking. Two mechanisms underlying cooperation were revealed: internalization of prosocial norm, and compliance in which cooperation was unaccompanied by correspondent changes in normative beliefs. The Fishbein model was applicable only to change through internalization. A linear assumption in the Fishbein model between evaluative attitude and behavior should be reexamined in its application to a social dilemma.

    2015-01-01

    We proposed a conceptual model to predict binge-drinking behavior among college students, based on the theory of planned behavior and the stress-coping hypothesis. A two-wave online survey was conducted with predictors and drinking behavior measured separately over 2 weeks' time. In the Wave 1 survey, 279 students at a public university in the United States answered questions assessing key predictors and individual characteristics. In the Wave 2 survey, 179 participants returned and reported their drinking behavior over 2 weeks' time. After conducting a negative binomial regression, we found that more favorable attitude toward drinking and less perceived control of drinking at Wave 1 were associated with more binge drinking at Wave 2; subjective norm at Wave 1 was not a significant predictor of binge drinking at Wave 2; students with higher stress at Wave 1 engaged in more binge drinking at Wave 2, but those with higher loneliness did not. Implications of findings are discussed.

    Seasonal fluctuations in food availability show a tight association with seasonal variations in body weight and food intake. Seasonal variations in food intake, energy storage, and expenditure appear to be a widespread phenomenon suggesting they may have evolved in anticipation for changing environmental demands. These cycles appear to be driven by changes in external daylength acting on neuroendocrine pathways. A number of neuroendocrine pathways, two of which are the endocrine mechanisms underlying feeding and stress, appear to show seasonal changes in both their circulating levels and reactivity. As such, variation in the level or reactivity to these hormones may be crucial factors in the control of seasonal variations in food-seeking behaviors. The present review examines the relationship between feeding behavior and seasonal changes in circulating hormones. We hypothesize that seasonal changes in circulating levels of glucocorticoids and the feeding-related hormones ghrelin and leptin contribute to seasonal fluctuations in feeding-related behaviors. This review will focus on the seasonal circulating levels of these hormones as well as sensitivity to these hormones in the modulation of food-seeking behaviors.

    Groundwater is the major source to meet domestic, industrial and agricultural needs in the city of Dar es Salaam, Tanzania. However, population growth, increasing urbanization, industrialization and tourism, and climatic changes have caused an intensive exploitation of groundwater resources leading the aquifers become more vulnerable to seawater intrusion. The aim of this study is to examine the variations of groundwater chemistry (as resulting from natural and anthropogenic inputs) depending on seasonal changes, in order to evaluate water quality for drinking and irrigation purposes. Physical and chemical data come from the analysis of groundwater samples, collected from 72 wells, used for the evaluation of water quality parameters, during a year of monitoring. Pattern diagrams, geochemical modeling techniques and Principal Component Analysis (PCA) have been used to identify the main factors influencing groundwater composition. Based on the hydrochemistry, the groundwater was classified into three types: (a) Na-Cl, (b) Ca-Cl, (c) mixed Ca-Na-HCO3-Cl (d) mixed Ca-Mg-Cl-SO4. The geochemical modeling results show that groundwater chemistry is mainly influenced by evaporation process, as it is suggested by the increase of Na and Cl ions concentrations. According to irrigation water quality assessment diagrams of USDA, most water samples from dry and rainy seasons, distributed in category C2-S1, C3-S1, C3-S2, C4-S2 highlighting medium to very high salinity hazard and low to medium sodium content class. PCA evidenced the role of seawater intrusion, evaporation process and anthropogenic pollution (i.e. high NO3 levels due to agricultural activities), as the major factors that influenced the water chemistry, and hence the water quality. Based on Pearson correlation matrix, the presence of high correlations (>0.8) among Na, Cl, Mg and SO4, in association with EC, were interpreted as the seawater intrusion effects. In this area groundwater quality is generally low, and

    Full Text Available The carbonated soft drinks intake has changed the children eating habits. This factor may be directly associated with arterial hypertension due the high consumption of sodium present in foods and drinks industrialized. This study was to compare sodium levels between two different types of carbonated soft drinks, carbonated sugar drinks and diet drinks to define what type of drink has the lowest sodium content and alerting healthcare professionals about the presence of sodium in industrialized beverages. The study included labels of carbonated soft drinks n = 33 – sugar drinks (n = 21 or diet drinks (n = 12 – of five different flavors.All carbonated soft drinks evaluated have sodium in its composition. However, the sodium presence in carbonated sugar drinks was significantly lower when compared with carbonated diet drinks (69.05 ± 16.55 vs. 145.30 ± 47.36mg Na/l, respectively.Studies to identify children's eating habits related with increased consumption of foods and drinks manufactured are needed to identify, reduce and prevent high blood pressure.

    Non carious lesions, including erosion changes, are becoming increasingly apparent. There are multiple factors involved in the etiology of dental erosion i.a. acids in commercially available drinks. The aim of this study was to determine the frequency of soft drink consumption that promote dental erosion among young adults. The 266 subjects were asked to fill in a questionnaire. The questionnaire inquired questions about consumption of drinks favouring tooth erosion. The students declared frequent drinking of isotonic drinks, energetic drinks, fizzy drinks and coca-cola type drinks. On the basis of a survey of Poznań University of Medical Sciences students it can be determined, that they have relatively high risk of dental erosion. To minimize the risk of dental erosion occurrence in young population there is a need to disseminate knowledge about the etiology.

    In real urban traffic, roadways are usually multilane with lane-specific velocity limits. Most previous researches are derived from single-lane car-following theory which in the past years has been extensively investigated and applied. In this paper, we extend the continuous single-lane car-following model (full velocity difference model) to simulate the three-lane-changing behavior on an urban roadway which consists of three lanes. To meet incentive and security requirements, a comprehensive lane-changing rule set is constructed, taking safety distance and velocity difference into consideration and setting lane-specific speed restriction for each lane. We also investigate the effect of lane-changing behavior on distribution of cars, velocity, headway, fundamental diagram of traffic and energy dissipation. Simulation results have demonstrated asymmetric lane-changing “attraction” on changeable lane-specific speed-limited roadway, which leads to dramatically increasing energy dissipation.

    After weaning, male and female Wistar rats were fed a daily diet containing 1 g lead acetate/kg food until a level of about 20 micrograms/100 mL blood was obtained. The male rats were subjected to the different behavioral tests, whereas the females were mated to untreated males and further exposed until weaning of the offspring. Behavioral testing of the male offspring was performed between 3 and 4 months of age. General behavior of both groups was tested in the open-field task including locomotion, local movements, and emotionality. The conditioned instrumental behavior was tested in the Skinner box from simple to more complex programs. The blood-lead level was measured by flameless atomic absorption spectrometry. No behavioral changes became apparent in the open-field task and in the preliminary operant training. In the more complex programs (DRH = Differential Reinforcement of High Rates), the rats exposed to lead after weaning showed slight changes of DRH performance. By contrast, in pre- and neonatally exposed animals, DRH performance was significantly increased, although blood-lead levels had returned to normal at the time of testing. A comparison of lead effects in animals to possible effects in man is discussed in this paper, and it is concluded that lead exposure to man at doses which presently are suggested to be innocuous may result in subclinical functional changes of the central nervous system.

    2009-08-01

    Full Text Available Abstract Background A number of gene expression studies have investigated changes induced by drug exposure, but few reports describe changes that persist following relapse. In this study, genome-wide analysis of gene expression was conducted following an extinction session (90 min in rats that expressed behavioral incubation of heroin-seeking and goal-directed behavior. As an important modulator of goal-directed behavior, the medial prefrontal cortex (mPFC was the target of genomic analysis. Rats were trained to self-administer heroin during 3 h daily sessions for 14 d. Following the self-administration period, rats were reintroduced to the self-administration chambers for a 90-minute extinction session in which they could seek heroin, but received none. Extinction sessions were conducted on groups after either 1 d or 14 d of drug-free enforced abstinence to demonstrate behavioral incubation. Results Behavioral data demonstrated incubation (increased expression of heroin-seeking and goal-directed behavior after the 14 d abstinent period. That is, following 14 d of enforced abstinence, animals displayed heightened drug-seeking behavior when returned to the environment where they had previously received heroin. This increased drug-seeking took place despite the fact that they received no drug during this extinction session. Whole genome gene expression analysis was performed and results were confirmed by quantitative real-time PCR (RT-qPCR. Microarrays identified 66 genes whose expression was identified as changed by at least 1.4 fold (p bdnf, calb1, dusp5, dusp6, egr1, npy, rgs2. Conclusion Ontological analysis indicates that several of the genes confirmed to be changed are important for neuroplasticity, and through that role may impact learning and behavior. The importance of drug-seeking behavior and memory of previous drug-taking sessions suggest that such genes may be important for relapse. The global gene expression analysis adds to the

    Knecht, S; Kenning, P

    2016-01-01

    In the past, medicine was dominated by acute diseases. Since treatments were unknown to patients they followed their medical doctors´ directives-at least for the duration of the disease. Behavior was thus largely motivated by avoiding expected costs associated with alternative behaviors (I-must). The health challenges prevailing today are chronic conditions resulting from the way we chose to live. Traditional directive communication has not been successful in eliciting and maintaining appropriate lifestyle changes. An approach successful in other fields is to motivate behavior by increasing expected rewards (I-want). Drawing on neuroeconomic and marketing research, we outline strategies including simplification, repeated exposure, default framing, social comparisons, and consumer friendliness to foster sustained changes in preference. We further show how these measures could be integrated into the health care system.

  12. Neural substrates of contingency learning and executive control: dissociating physical, valuative, and behavioral changes

    Directory of Open Access Journals (Sweden)

    O'Dhaniel A Mullette-Gillman

    2009-09-01

    Full Text Available Contingency learning is fundamental to cognition. Knowledge about environmental contingencies allows behavioral flexibility, as executive control processes accommodate the demands of novel or changing environments. Studies of experiential learning have focused on the relationship between actions and the values of associated outcomes. However, outcome values have often been confounded with the physical changes in the outcomes themselves. Here, we dissociated contingency learning into valuative and non-valuative forms, using a novel version of the two-alternative choice task, while measuring the neural effects of contingency changes using functional magnetic resonance imaging (fMRI. Changes in value-relevant contingencies evoked activation in the lateral prefrontal cortex (LPFC, posterior parietal cortex (PPC, and dorsomedial prefrontal cortex (DMPFC consistent with prior results (e.g., reversal-learning paradigms. Changes in physical contingencies unrelated to value or to action produced similar activations within the LPFC, indicating that LPFC may engage in generalized contingency learning that is not specific to valuation. In contrast, contingency changes that required behavioral shifts evoked activation localized to the DMPFC, supplementary motor, and precentral cortices, suggesting that these regions play more specific roles within the executive control of behavior.

    Altered myelin structure and oligodendrocyte function have been shown to correlate with cognitive and motor dysfunction and deficits in social behavior. We and others have previously demonstrated that social isolation in mice induced behavioral, transcriptional, and ultrastructural changes in oligodendrocytes of the prefrontal cortex (PFC). However, whether enhancing myelination and oligodendrocyte differentiation could be beneficial in reversing such changes remains unexplored. To test this hypothesis, we orally administered clemastine, an antimuscarinic compound that has been shown to enhance oligodendrocyte differentiation and myelination in vitro, for 2 weeks in adult mice following social isolation. Clemastine successfully reversed social avoidance behavior in mice undergoing prolonged social isolation. Impaired myelination was rescued by oral clemastine treatment, and was associated with enhanced oligodendrocyte progenitor differentiation and epigenetic changes. Clemastine induced higher levels of repressive histone methylation (H3K9me3), a marker for heterochromatin, in oligodendrocytes, but not neurons, of the PFC. This was consistent with the capability of clemastine in elevating H3K9 histone methyltransferases activity in cultured primary mouse oligodendrocytes, an effect that could be antagonized by cotreatment with muscarine. Our data suggest that promoting adult myelination is a potential strategy for reversing depressive-like social behavior. Significance statement: Oligodendrocyte development and myelination are highly dynamic processes influenced by experience and neuronal activity. However, whether enhancing myelination and oligodendrocyte differentiation is beneficial to treat depressive-like behavior has been unexplored. Mice undergoing prolonged social isolation display impaired myelination in the prefrontal cortex. Clemastine, a Food and Drug Administration-approved antimuscarinic compound that has been shown to enhance myelination under

    The random daytime (RDT) sampling method was used for the first time in the assessment of average weekly exposure to uranium through drinking water in a large water supply zone. Data set of uranium concentrations determined in 106 RDT samples collected in three runs from the water supply zone in Wroclaw (Poland), cannot be simply described by normal or log-normal distributions. Therefore, a numerical method designed for the detection and calculation of bimodal distribution was applied. The extracted two distributions containing data from the summer season of 2011 and the winter season of 2012 (nI=72) and from the summer season of 2013 (nII=34) allowed to estimate means of U concentrations in drinking water: 0.947 μg/L and 1.23 μg/L, respectively. As the removal efficiency of uranium during applied treatment process is negligible, the effect of increase in uranium concentration can be explained by higher U concentration in the surface-infiltration water used for the production of drinking water. During the summer season of 2013, heavy rains were observed in Lower Silesia region, causing floods over the territory of the entire region. Fluctuations in uranium concentrations in surface-infiltration water can be attributed to releases of uranium from specific sources - migration from phosphate fertilizers and leaching from mineral deposits. Thus, exposure to uranium through drinking water may increase during extreme rainfall events. The average chronic weekly intakes of uranium through drinking water, estimated on the basis of central values of the extracted normal distributions, accounted for 3.2% and 4.1% of tolerable weekly intake.

    2008-08-01

    The current study investigated relationships among aggressive behavior, change in salivary testosterone concentrations, and willingness to engage in a competitive task. Thirty-eight male participants provided saliva samples before and after performing the Point Subtraction Aggression Paradigm (a laboratory measure that provides opportunity for aggressive and defensive behavior while working for reward; all three involve pressing specific response keys). Baseline testosterone concentrations were not associated with aggressive responding. However, aggressive responding (but not point reward or point protection responding) predicted the pre- to post-PSAP change in testosterone: Those with the highest aggressive responding had the largest percent increase in testosterone concentrations. Together, aggressive responding and change in testosterone predicted willingness to compete following the PSAP. Controlling for aggression, men who showed a rise in testosterone were more likely to choose to compete again (p=0.03) and controlling for testosterone change, men who showed the highest level of aggressive responding were more likely to choose the non-competitive task (p=0.02). These results indicate that situation-specific aggressive behavior and testosterone responsiveness are functionally relevant predictors of future social behavior.

J Strength Cond Res 30(7): 1862-1870, 2016-Because caffeine ingestion has been found to increase muscle strength, our aim was to determine whether caffeine when combined with other potential ergogenic ingredients, such as those in commercial energy drinks, would have a similar effect. Fifteen young healthy subjects were used in a double-blind, repeated-measures experimental design. Each subject performed 3 trials, ingesting either a caffeinated energy drink, an uncaffeinated version of the drink, or a placebo drink. The interpolated twitch procedure was used to assess maximum voluntary isometric contraction (MVIC) strength, electrically evoked strength, and percent muscle activation during MVIC of the knee extensors both before and after drink ingestion, and after a fatiguing bout of contractions; electromyographic (EMG) amplitude of the knee extensors during MVIC was also assessed. The mean (±SE) change in MVIC strength from before to after drink ingestion was significantly greater for the caffeinated energy drink compared with placebo [+5.0 (±1.7) vs. -0.5 (±1.5)%] and the difference between the drinks remained after fatigue (p = 0.015); the strength changes for the uncaffeinated energy drink were not significantly different from those of the other 2 drinks at any time. There was no significant effect of drink type on the changes in electrically evoked strength, percent muscle activation, and EMG from before to after drink ingestion. This study indicates that a caffeinated energy drink can increase MVIC strength but the effect is modest and the strength increase cannot be attributed to increased muscle activation. Whether the efficacy of energy drinks can be attributed solely to caffeine remains unclear.

  20. Examining factors associated with heavy episodic drinking among college undergraduates

    Directory of Open Access Journals (Sweden)

    Kristen Scholly

    2014-08-01

    Full Text Available Heavy episodic drinking among college students is a serious health concern. The purpose of this study was to identify factors associated with heavy episodic drinking behaviors amongst a predominately Asian undergraduate college student population in the United States. A survey measuring alcohol use behaviors was completed by a random sample of 18-24 year old undergraduates during April, 2011. A multivariate logistic regression analysis was conducted to determine factors associated with students’ heavy episodic drinking behavior. Independent factors associated with heavy episodic drinking included living on campus, ethnicity, perceived drinking behavior among peers, and a belief that alcohol is a central part of one’s social life. Heavy episodic drinking was also associated with poor academic performance. Campus-wide educational strategies to reduce heavy episodic drinking among college undergraduates should incorporate accurate information regarding alcohol use norms to correct students’ perceived over estimation of their peers alcohol consumption rates and the under estimation of students protective alcohol use behaviors. These efforts should focus in on-campus residence halls where a higher occurrence of heavy episodic drinking is often found.

    Rizak, S; Hrudey, Steve E

    2008-01-01

    A targeted review of documented waterborne disease outbreaks over the past decades reveals some recurring themes that should be understood by drinking-water suppliers. Evidence indicates the outbreaks are often linked to some significant change in conditions that provides a sudden challenge to a water system. Severe weather events, such as heavy rainfall or runoff from snow melt, as well as treatment process and system changes, are common risk factors for drinking-water outbreaks. Failure to recognise warning signs and complacency are important contributors to drinking water becoming unsafe. Drinking-water suppliers must focus on competence and vigilance in maintaining effective multiple barriers appropriate to the challenges facing the drinking-water system. Understanding the risk factors and failure modes of waterborne disease outbreaks is an essential component for effective management of community drinking-water supplies and ensuring the delivery of safe drinking-water to consumers.

    2014-09-01

    Drinking games are a high-risk social drinking activity consisting of rules and guidelines that determine when and how much to drink (Polizzotto et al., 2007). Borsari's (2004) seminal review paper on drinking games in the college environment succinctly captured the published literature as of February 2004. However, research on college drinking games has grown exponentially during the last decade, necessitating an updated review of the literature. This review provides an in-depth summary and synthesis of current drinking games research (e.g., characteristics of drinking games, and behavioral, demographic, social, and psychological influences on participation) and suggests several promising areas for future drinking games research. This review is intended to foster a better understanding of drinking game behaviors among college students and improve efforts to reduce the negative impact of this practice on college campuses.

    2009-12-01

    Full Text Available Reduced nicotinamide adenine dinucleotide (NADH dehydrogenase subunit 2 237 leucine/methionine (ND2-237 Leu/Met polymorphism, is reportedly associated with longevity in the Japanese population. The ND2-237Met genotype may exert resistance to atherogenic diseases, such as myocardial infarction or cerebrovascular disorders. To investigate whether ND2-237 Leu/Met polymorphism is associated with yearly changes in serum lipid levels, we conducted a longitudinal study of 107 healthy Japanese male subjects. Analysis of covariance revealed that the interaction between the ND2-237 Leu/Met genotypes and habitual drinking was significantly associated with yearly changes in serum total cholesterol (TC and low-density lipoprotein cholesterol (LDLC levels (p0.036 and p0.006, respectively. In multiple regression analysis, daily drinking was significantly and positively associated with yearly changes in serum LDLC levels in men with ND2-237Met (p0.026. After adjusting for covariates, yearly changes in serum LDLC levels were significantly lower in non-daily drinkers with ND2-237Met than in those with ND2-237Leu (p0.047. These results suggest that ND2-237Met has a beneficial impact on yearly changes in serum LDLC in non-daily drinkers but not in daily drinkers.

  5. Morphological and behavioral changes in the pathogenesis of a novel mouse model of communicating hydrocephalus.

    Directory of Open Access Journals (Sweden)

    Allison B McMullen

    Full Text Available The Ro1 model of hydrocephalus represents an excellent model for studying the pathogenesis of hydrocephalus due to its complete penetrance and inducibility, enabling the investigation of the earliest cellular and histological changes in hydrocephalus prior to overt pathology. Hematoxylin and eosin staining, immunofluorescence and electron microscopy were used to characterize the histopathological events of hydrocephalus in this model. Additionally, a broad battery of behavioral tests was used to investigate behavioral changes in the Ro1 model of hydrocephalus. The earliest histological changes observed in this model were ventriculomegaly and disorganization of the ependymal lining of the aqueduct of Sylvius, which occurred concomitantly. Ventriculomegaly led to thinning of the ependyma, which was associated with periventricular edema and areas of the ventricular wall void of cilia and microvilli. Ependymal denudation was subsequent to severe ventriculomegaly, suggesting that it is an effect, rather than a cause, of hydrocephalus in the Ro1 model. Additionally, there was no closure of the aqueduct of Sylvius or any blockages within the ventricular system, even with severe ventriculomegaly, suggesting that the Ro1 model represents a model of communicating hydrocephalus. Interestingly, even with severe ventriculomegaly, there were no behavioral changes, suggesting that the brain is able to compensate for the structural changes that occur in the pathogenesis of hydrocephalus if the disorder progresses at a sufficiently slow rate.

  6. Adolescent intake of caffeinated energy drinks does not affect adult alcohol consumption in C57BL/6 and BALB/c mice.

    2016-08-01

    The rise in marketing and mass consumption of energy drink products by adolescents poses a largely unknown risk on adolescent development and drug reward. Yet, with increasing reports of acute health issues present in young adults who ingest large quantities of energy drinks alone or in combination with alcohol, the need to elucidate these potential risks is pressing. Energy drinks contain high levels of caffeine and sucrose; therefore, exposure to energy drinks may lead to changes in drug-related behaviors since caffeine and sucrose consumption activates similar brain pathways engaged by substances of abuse. With a recent study observing that adolescent caffeine consumption increased cocaine sensitivity, we sought to investigate how prolonged energy drink exposure in adolescence alters alcohol use and preference in adulthood. To do so, we utilized three different energy drink exposure paradigms and two strains of male mice (C57BL/6 and BALB/c) to monitor the effect of caffeine exposure via energy drinks in adolescence on adult alcohol intake. These paradigms included two models of volitional consumption of energy drinks or energy drink-like substances and one model of forced consumption of sucrose solutions with different caffeine concentrations. Following adolescent exposure to these solutions, alcohol intake was monitored in a limited-access, two-bottle choice between water and increasing concentrations of alcohol during adulthood. In none of the three models or two strains of mice did we observe that adolescent 'energy drink' consumption or exposure was correlated with changes in adult alcohol intake or preference. While our current preclinical results suggest that exposure to large amounts of caffeine does not alter future alcohol intake, differences in caffeine metabolism between mice and humans need to be considered before translating these results to humans.

    Methamphetamine (METH) is a major drug of abuse worldwide, and no efficient therapeutic strategies for treating METH addiction are currently available. Continuous METH use can cause behavioral upregulation or psychosis. The dopaminergic pathways, particularly the neural circuitry from the ventral tegmental area to the nucleus accumbens (NAc), have a critical role in this behavioral stage. Acupuncture has been used for treating diseases in China for more than 2000 years. According to a World Health Organization report, acupuncture can be used to treat several functional disorders, including substance abuse. In addition, acupuncture is effective against opioids addiction. In this study, we used electroacupuncture (EA) for treating METH-induced behavioral changes and investigated the possible therapeutic mechanism. Results showed that EA at the unilateral Zhubin (KI9)–Taichong (LR3) significantly reduced METH-induced behavioral sensitization and conditioned place preference. In addition, both dopamine and tyrosine hydroxylase (TH) levels decreased but monoamine oxidase A (MAO-A) levels increased in the NAc of the METH-treated mice receiving EA compared with those not receiving EA. EA may be a useful nonpharmacological approach for treating METH-induced behavioral changes, probably because it reduces the METH-induced TH expression and dopamine levels and raises MAO-A expression in the NAc.

    Objective Roux-en-Y gastric bypass (RYGB) surgery causes greater weight loss than laparoscopic adjustable gastric banding (LAGB). We tested the hypothesis that RYGB has weight loss-independent effects on taste perception which influence eating behavior and contribute to the greater weight loss. Design and Methods Subjects were studied before and after ~20% weight loss induced by RYGB (n=17) or LAGB (n=10). We evaluated: taste sensitivity for sweet, salty and savory stimuli; sucrose and monosodium glutamate (MSG) preferences; sweetness palatability; eating behavior; and expression of taste-related genes in biopsies of fungiform papillae. Results Weight loss induced by both procedures caused the same decrease in: preferred sucrose concentration (−12±10%), perceived sweetness of sucrose (−7±5%), cravings for sweets and fast-foods (−22 ±5%), influence of emotions (−27±5%) and external food cues (−30±4%) on eating behavior, and expression of α-gustducin in fungiform papillae (all P-values <0.05). RYGB, but not LAGB, shifted sweetness palatability from pleasant to unpleasant when repetitively tasting sucrose (P=0.05). Neither procedure affected taste detection thresholds or MSG preferences. Conclusions LAGB and RYGB cause similar alterations in eating behaviors, when weight loss is matched. These changes in eating behavior were not associated with changes in taste sensitivity, suggesting other, as yet unknown, mechanisms are involved. PMID:24167016

    The aim of this study was to describe the prevalence and predictors of alcohol drinking behavior in children. Data were obtained from 367 children, aged 8-12 years (M = 10.44 years, SD = 1.21 years; 61.9% female) from the city of Córdoba, Argentina. Several scales were used to assess risk factors, including personality traits, alcohol expectancy (i.e., beliefs about the consequences of using alcohol), and perceived peer alcohol use, for alcohol drinking and alcohol drinking experiences. Hierarchical regression analysis was used to determine the contribution of multiple risk factors to the quantity of alcohol consumed. The results showed that 58% of the children had tasted alcohol, and approximately one-third drank alcohol again after the first drinking experience. Twelve-year-old children had a significantly higher prevalence of tasting and drinking alcohol and a significantly greater frequency and quantity of alcohol consumed than younger children. Eighty percent of the children who liked alcohol during their first drinking experience reported that they drank alcohol again. Among the children who did not like alcohol during their first drinking experience, only 31% drank alcohol again. Underage drinking usually occurred under adult supervision in family settings when parents or other relatives allowed them to drink or were aware of their children's drinking. The hierarchical regression analysis showed that being older and male, having more peers that drink alcohol, having higher levels of extroversion, and having alcohol expectancy for social facilitation increased the risk for greater alcohol use. The final model explained 33% of the total variance.

    As it is still unclear to what extent parental drinking is a predictor of children's alcohol use, we tested the association of specific paternal and maternal drinking patterns with both initiation and development of adolescent alcohol use. Longitudinal data (four annual measurements) of parent-child dyads (N=2319) have been used. Parental drinking patterns have been identified using latent class analysis. The association of parental drinking patterns with the initiation and development of 12-15 year olds' drinking have been examined with latent growth curve modeling. Only two out of six parental drinking patterns were related to adolescent drinking. That is, having a heavy drinking father or two heavy episodic drinking parents particularly predicts early and heavier adolescent drinking. When controlled for parenting behaviors and background variables, such as adolescent gender, age and socioeconomic status (SES), these findings remained significant. Interaction analyses revealed that the influence of parental heavy (episodic) drinking differs across gender and is especially strong among adolescents with lower SES. Thus, parental heavy (episodic) drinking, and not so much the frequency of drinking, predicts the initiation and development of alcohol consumption in their offspring. Parents and professionals must be aware that parental heavy drinking affects their offspring, particularly adolescents with lower SES, resulting in earlier and heavier drinking among this high-risk group.

    Over 250 respondents - graduate students in law and public policy - assessed the risks of climate change and valued climate-change mitigation policies. Many aspects of their behavior were consistent with rational behavior. For example, respondents successfully estimated distributions of temperature increases in Boston by 2100. The median value of best estimates was 1-3 degrees Fahrenheit. In addition, people with higher risk estimates, whether for temperature or related risks (e.g., hurricane intensities) offered more to avoid warming. Median willingness to pay (WTP) to avoid global warming was $0.50/gallon, and 3% of income. And important scope tests (e.g., respondents paid more for bigger accomplishments) were passed. However, significant behavioral propensities also emerged. For example, accessibility of neutral information on global warming boosted risk estimates. Warming projections correlated with estimates for unrelated risks, such as earthquakes and heart attacks. The implied WTP for avoidance was much greater when asked as a percent of income than as a gas tax, a percent thinking bias. Home team betting showed itself; individuals predicting a Bush victory predicted smaller temperature increases. In the climate-change arena, behavioral decision tendencies are like a fun-house mirror: They magnify some estimates and shrink others, but the contours of rational decision remain recognizable.

    There is evidence to suggest that low levels of magnesium (Mg) are associated with affective disorders, however, causality and central neurobiological mechanisms of this link are largely unproven. We have recently shown that mice fed a low Mg-containing diet (10% of daily requirement) display enhanced depression-like behavior sensitive to chronic antidepressant treatment. The aim of the present study was to utilize this model to gain insight into underlying mechanisms by quantifying amygdala/hypothalamus protein expression using gel-based proteomics and correlating changes in protein expression with changes in depression-like behavior. Mice fed Mg-restricted diet displayed reduced brain Mg tissue levels and altered expression of four proteins, N(G),N(G)-dimethylarginine dimethylaminohydrolase 1 (DDAH1), manganese-superoxide dismutase (MnSOD), glutamate dehydrogenase 1 (GDH1) and voltage-dependent anion channel 1. The observed alterations in protein expression may indicate increased nitric oxide production, increased anti-oxidant response to increased oxidative stress and potential alteration in energy metabolism. Aberrant expressions of DDAH1, MnSOD and GDH1 were normalized by chronic paroxetine treatment which also normalized the enhanced depression-like behavior, strengthening the link between the changes in these proteins and depression-like behavior. Collectively, these findings provide first evidence of low magnesium-induced alteration in brain protein levels and biochemical pathways, contributing to central dysregulation in affective disorders.

  14. Behavior Change or Empowerment: On the Ethics of Health-Promotion Goals.

    One important ethical issue for health promotion and public health work is to determine what the goals for these practices should be. This paper will try to clarify what some of these goals are thought to be, and what they ought to be. It will specifically discuss two different approaches to health promotion, such as, behavior change and empowerment. The general aim of this paper is, thus, to compare the behavior-change approach and the empowerment approach, concerning their immediate (instrumental) goals or aims, and to morally evaluate the strengths and weaknesses of these two goal models, in relation to the ultimate goal of health promotion. The investigation shows that the behavior-change approach has several moral problems. First of all, it is overly paternalistic and often disregards the individual's or group's own perception of what is important-something that also increases the risk of failed interventions. Furthermore, it risks leading to 'victim blaming' and stigmatization, and to increased inequalities in health, and it puts focus on the 'wrong' problems, i.e., behavior instead of the 'causes of the causes'. It is thereafter shown that the empowerment approach does not have any of these problems. Finally, some specific problems for the empowerment approach are discussed and resolved, such as, the idea that empowering some groups might lead to power over others, the objection that the focus is not primarily on health (which it should be), and the fact that empowered people might choose to live lives that risk reducing their health.

    This unmatched case-control study aimed to determine the relationship among caffeine drinks consumption known as "energy drinks consumption", drug dependence and related factors in male construction workers in Chonburi Province. It was conducted during December 15, 2001 and February 15, 2002. Data were collected using interview questionnaires. The logistic regression was used to control possible confounding factors. The subjects consisted of 186 cases who had consumed energy drinks for more than 3 months and 186 controls who had given up for more than 3 months. They were frequency/group matched by age group. There was statistically significant association among energy drinks consumption and overtime work, motivation from advertisements, positive attitude of energy drinks consumption, alcohol drinks, smoking and ex-taking Kratom behavior. Multivariate analyses revealed that only 5 factors were related to energy drinks consumption: marital status (OR = 1.88, 95%CI: 1.14, 3.11), overtime work (OR = 2.84, 95%CI: 1.73, 4.64), motivation from advertisements (OR = 2.72, 95%CI: 1.67, 4.42), positive attitude of energy drinks consumption (OR = 4.06, 95%CI: 1.65, 10.01) and ex-taking Kratom behavior (OR = 2.77, 95%CI: 1.19, 6.44). As a result, construction workers should be provided with the knowledge of energy drinks consumption, the effect of drug dependence behavior, and the advantages of safe and healthy food that is cheap, readily available, and rich in nutrients.

    Early insults to the thalamus result in functional and/or structural abnormalities in the cerebral cortex. However, differences in behavioral and cognitive changes after early insult are not well characterized. The present study assessed whether early postnatal damage to mediodorsal nucleus of the thalamus (MD), reciprocally interconnected with the prefrontal cortex, causes behavioral and cognitive alterations in young adult rats. Rat pups at postnatal day 4 received bilateral electrolytic lesion of MD, or a MD Sham lesion or were anesthetized controls; on recovery they were returned to their mothers until weaning. Seven weeks later, all rats were tested with the following behavioral and cognitive paradigms: T-maze test, open field test, actimetry, elevated plus maze test, social interactions test and passive avoidance test. Rats with bilateral MD damage presented with disrupted recognition memory, deficits in shifting response rules, significant hypoactivity, increased anxiety-like behavior, deficits in learning associations as well as decreased locomotor activity, and reduced social interactions compared to MD Sham lesion and anesthetized Control rats. The lesion also caused significant decreases in pyramidal cell density in three frontal cortex regions: medial infralimbic cortex, dorsolateral anterior cortex, and cingulate Cg1 cortex. The present findings suggest a functional role for MD in the postnatal maturation of affective behavior. Further some of the behavioral and cognitive alterations observed in these young adult rats after early MD lesion are reminiscent of those present in major psycho-affective disorders, such as schizophrenia in humans.

    Reduced expression of the Gad1 gene-encoded 67-kDa protein isoform of glutamic acid decarboxylase (GAD67) is a hallmark of schizophrenia. GAD67 downregulation occurs in multiple interneuronal sub-populations, including the parvalbumin-positive (PVALB+) cells. To investigate the role of the PV-positive GABAergic interneurons in behavioral and molecular processes, we knocked down the Gad1 transcript using a microRNA engineered to target specifically Gad1 mRNA under the control of Pvalb bacterial artificial chromosome. Verification of construct expression was performed by immunohistochemistry. Follow-up electrophysiological studies revealed a significant reduction in γ-aminobutyric acid (GABA) release probability without alterations in postsynaptic membrane properties or changes in glutamatergic release probability in the prefrontal cortex pyramidal neurons. Behavioral characterization of our transgenic (Tg) mice uncovered that the Pvalb/Gad1 Tg mice have pronounced sensorimotor gating deficits, increased novelty-seeking and reduced fear extinction. Furthermore, NMDA (N-methyl-d-aspartate) receptor antagonism by ketamine had an opposing dose-dependent effect, suggesting that the differential dosage of ketamine might have divergent effects on behavioral processes. All behavioral studies were validated using a second cohort of animals. Our results suggest that reduction of GABAergic transmission from PVALB+ interneurons primarily impacts behavioral domains related to fear and novelty seeking and that these alterations might be related to the behavioral phenotype observed in schizophrenia.

    Dolphins rely on whistles to identify each other and to receive and convey information about their environment. Although capable of adjusting these signals with changing environments, there is little information on how dolphins acoustically respond to different watercraft activities and if this response depends on dolphin behavioral state. Bottlenose dolphin whistles were recorded in the presence of research and dolphin-watching boats. Dolphins emitted lower frequency and longer whistles when interacting with dolphin-watching boats, particularly during foraging activities. This study suggests that dolphin-watching boat traffic significantly hinders dolphin communication during important behavioral states.

    Skillful, collaborative conversations are powerful tools to improve physical and mental health. Whether you are a parent talking with your child about the dangers of substance abuse, an educator concerned about a student’s signs of psychological distress, a veteran worried about a buddy who is contemplating suicide, or a healthcare professional wanting to better engage patients to increase treatment compliance, having the skill, confidence and motivation to engage in conversations can truly transform the health and well-being of those you interact with. Kognito develops role-play simulations that prepare individuals to effectively lead real-life conversations that measurably improve social, emotional, and physical health. The behavior change model that drives the simulations draws upon components of game mechanics, virtual human simulation technology and integrates evidence-based instructional design components as well as principles of social-cognitive theory and neuroscience such as motivational interviewing, emotional regulation, empathy and mindfulness. In the simulations, users or enter a risk-free practice environment and engage in a conversation with intelligent, fully animated, and emotionally responsive virtual characters that model human behavior. It is in practicing these conversations, and receiving feedback from a virtual coach, that users learn to better lead conversations in real life. Numerous longitudinal studies have shown that users who complete Kognito simulations demonstrate statistically significant and sustained increases in attitudinal variables that predict behavior change including preparedness, likelihood, and self-efficacy to better manage conversations. Pending the target population, each online or mobile simulation resulted in desired behavior changes ranging from increased referrals of students, patients or veterans in psychological distress to mental health support services, or increasing physician patient-centered communication or

    This study focused on how climate change-induced effects on weather will translate into changes in wildland fire severity and outcomes in California, particularly on the effectiveness of initial attack at limiting the number of fires that escape initial attack. The results indicate that subtle shifts in fire behavior of the sort that might be induced by the climate changes anticipated for the next century are of sufficient magnitude to generate an appreciable increase in the number of fires that escape initial attack. Such escapes are of considerable importance in wildland fire protection planning, given the high cost to society of a catastrophic escape like those experienced in recent decades in the Berkeley-Oakland, Santa Barbara, San Diego, or Los Angeles areas. However, at least for the three study areas considered, it would appear that relatively modest augmentations to existing firefighting resources might be sufficient to compensate for change-induced changes in wildland fire outcomes.
