    The purpose of this study was to understand and predict Korean homemakers' attitudes, subjective norms, and intentions toward energy conservation behaviors. The reasoned action model was adopted to accomplish the objective. The household energy consumption could be determined by person's personal factors including behavioral beliefs, subjective norms, normative beliefs, motivation to comply, attitudes, and subjective norms. Therefore, the change of person's behaviors could influence energy consumption in the household. The subjects' intentions were explained by path analysis to test the explanatory model. The Korean households' intentions were significantly accounted for by past behaviors, behavioral beliefs, motivation to comply, and subjective norms. The insignificant relationship between attitudes and intentions may be happened by the cultural difference. That is, Korean households were more concerned about the social standards rather than personal standards. This study showed that in order to facilitate energy conservation behaviors in the household level, the program should provide households the manifest results of the conservation behaviors and the households member would be the good messengers to diffuse energy conservation information and the program should be planned based on the subjects' characteristics such income and education level.

    The aim of this study was to describe the attitude and subjective norm of dental practitioners towards practicing the atraumatic restorative treatment (ART) in Tanzania. A pre-tested questionnaire on attitudes and subjective norms to practice ART was mailed to all 147 dental practitioners working in the regional and district government clinics. The independent variables were: gender, working experience, qualification and ever heard of ART. The dependent variables were: attitude, subjective norm and intention to practice ART. Chi-square tests and multiple regression analysis were used to test for effects between independent and dependent variables. Significance level was set at 5%. A total of 138 practitioners returned completed questionnaires. More experienced dental practitioners encountered moderate social pressure than less experienced dental practitioners, who met strong social pressure (p=0.045). A total of 73.2% of dental practitioners felt that ART was worth introducing in Tanzania, 92.8% recommended ART training for all dental practitioners and 97.8% recommended inclusion of ART in dental curricula. Positive attitude, strong subjective norm and high intention to practice ART were recorded in 76.3%, 28.1% and 90.6% of the practitioners, respectively. Only subjective norm had a statistically significant influence on the intention to practice ART (p<0.0001). The results indicated that dental practitioners were willing to have ART introduced in Tanzania and had positive attitudes towards practicing this technique. Nevertheless, their intention to perform ART was strongly influenced by social pressures. Therefore, in order to have a successful introduction of ART in Tanzania, people who matter in the daily practice of dental practitioners need to accept and appraise the ART approach positively.

    2014-03-01

    The primary aim of this study was to understand factors associated with condom use behavior among club-working women and identify the most influential factors to be addressed in future health programs. A total of 158 club-working women were surveyed from 3 midsize cities in South Korea from July to September 2004. Survey questionnaires were developed based on the theory of planned behavior. A total of 7 distinct themes emerged: Health aspects, Customer related, Pleasure related, Finance related, Societal norm, Occupational norm, and Perceived control. The results indicated that the Customer-related theme, Societal norm, and Occupational norm were statistically significant factors affecting condom use. On the other hand, self-related factors such as health, pleasure, and finance are not significantly related to the condom use behavior of club-working women in South Korea, suggesting that the currently used knowledge-focused education programs may not be sufficient for this population.

    Fruit and vegetable (FV) attitudes and norms have been shown to influence intake in youth; yet research with low-income youth and studies supplementing self-report with objective measures of intake are lacking. Cross-sectional survey data on self-rated FV intake, FV attitudes, and FV norms were collected in a sample of 116 youth attending a residential summer camp serving low-income families. FV intake also was estimated by direct observation. Differences between self-rated and observed FV intake, perceived and observed peer intake, and perceived and peer-reported attitudes toward eating FVs were assessed with paired samples t tests. The role of FV attitudes, descriptive norms (perceived peer FV intake), injunctive norms (perceived peer attitudes toward eating FVs), and actual norms (observed peer FV intake and peer-reported FV attitudes) in predicting FV intake also was examined with multiple regression analysis. Youth misperceived their own and their peers' FV intake (i.e., overestimated intake of fruit and underestimated intake of vegetables) and believed that peers held less favorable attitudes toward eating FVs than was the case. The models predicting self-rated intake were significant, accounting for 34% of the variance in fruit intake and 28% of the variance in vegetable intake. Attitudes and descriptive norms were positively associated with FV intake, and observed peer fruit intake was negatively associated with fruit intake. Findings suggest that in low-income youth, FV attitudes, descriptive norms, and normative peer behavior predict perceived but not actual intake. Youth may benefit from intervention to promote favorable FV attitudes and norms. A focus on descriptive norms holds promise for improving self-rated intake in this population. PMID:25842389

    2014-01-01

    Racial disparities in health among African American men (AAM) in the United States are extensive. In contrast to their White counterparts, AAM have more illnesses and die younger. AAM have colorectal cancer (CRC) incidence and mortality rates 25% and 50% higher, respectively, than White men. Due to CRC’s younger age at presentation and high incidence among AAM, CRC screening (CRCS) is warranted at the age of 45 rather than 50, but little is known about younger AAM’s views of CRCS. Employing survey design, the purpose of the study was to describe the male role norms (MRN), knowledge, attitudes, perceived subjective norms, and perceived barriers associated with screening for CRC among a non-random sample of 157 young adult AAM (ages 19–45). Sixty-seven percent of the study sample received a passing knowledge score (85% or better), yet no significant differences were found among the three educational levels (i.e., low, medium, high). More negative attitudes toward CRCS correlated with the participants’ strong perceptions of barriers, but no extremely negative or positive MRN and perceived subjective norms were found. The factors significantly associated with attitudes were family history of cancer (unsure), work status, and perceived barriers. Findings from this study provide a solid basis for developing structured health education interventions that address the salient factors shaping young adult AAM’s view of CRC and early detection screening behaviors.

    2013-01-01

    Background Competitive hypothesis testing may explain differences in predictive power across multiple health behavior theories. Purpose We tested competing hypotheses of the Health Belief Model (HBM) and Theory of Reasoned Action (TRA) to quantify pathways linking subjective norm, benefits, barriers, intention, and mammography behavior. Methods We analyzed longitudinal surveys of women veterans randomized to the control group of a mammography intervention trial (n=704). We compared direct, partial mediation, and full mediation models with Satorra-Bentler ?2 difference testing. Results Barriers had a direct and indirect negative effect on mammography behavior; intention only partially mediated barriers. Benefits had little to no effect on behavior and intention; however, it was negatively correlated with barriers. Subjective norm directly affected behavior and indirectly affected intention through barriers. Conclusions Our results provide empiric support for different assertions of HBM and TRA. Future interventions should test whether building subjective norm and reducing negative attitudes increases regular mammography. PMID:23868613

    The interaction of car drivers and cyclists is one of the main causes of cycle incidents. The role of attitudes and social norms in shaping car drivers' aggressive behaviour towards cyclists, is not well understood and merits investigation. A sample of 276 drivers completed an online questionnaire concerning their attitudes towards cyclists, attitudes towards risky driving, perception of social norms concerning aggressive driving towards cyclists, and the frequency with which they engage in such aggressive driving behaviours. The results showed that attitudes towards cyclists, as well as social norm perceptions concerning aggressive driving towards cyclists, were associated with aggressive driving towards cyclists. Negative attitudes towards cyclists were more pronounced in non-cyclists than cyclists and their association with aggressive driving behaviour was stronger in cyclists than non-cyclists. The perception of social norms concerning aggressive driving towards cyclists had a stronger association with aggressive driving in non-cyclists than cyclists. Attitudes towards risk taking did not affect aggressive driving towards cyclists. These findings can inform campaigns that aim to improve cyclist and car driver interaction on the roads, making them safer to use for cyclists. PMID:26275525

    Dancers are at high risk of developing disordered eating attitudes, notably because of internalized thinness norms. Although the big five personality traits have been shown to be associated with eating attitudes in daily life, in dancers where eating issues and thinness norms internalization could be salient little is known about these associations and the role of the internalization of thinness norms in this relationship. The main objectives of this study were thus to examine the relationships between the personality traits defined in the big five model and the self-regulation of eating attitudes, and to assess the role of internalized thinness norms in this association. The study included 180 intensively training dancers with an average age of 15.6 years (SD = 2.8). Dancers completed questionnaires measuring the big five personality traits, internalization of thinness norms and self-regulation of eating attitudes in sport. Bootstrapped mediation analyses showed that neuroticism was negatively associated with self-regulation of eating attitudes, both directly and indirectly through the mediating role of internalized thinness norms. This study suggested that: (a) neuroticism is a vulnerability factor for self-regulation of eating attitudes in dancers, as already evidenced in the general population, and (b) the internalization of thinness norms is a pathway through which neuroticism affects self-regulation of eating attitudes. The big five model is therefore partially related to the internalization of thinness norms and eating attitudes in dancers. Key points The big five model relates to the internalization of thinness norms and eating attitudes in dancers. Neuroticism is negatively related to the self-regulation of eating attitudes. The internalization of thinness norms is correlated to the relationship between neuroticism and self-regulation of eating attitudes PMID:26336350

    This study examined the interactive effects of injunctive norm exposure and hostile and benevolent sexist attitudes on men's sexually aggressive responses during a behavioral analogue paradigm in which they interacted online with a bogus female partner. Heterosexual adult men (n?=?201), recruited from an online sample, read fictional information regarding other men's approval of misogynistic, paternalistic, or egalitarian treatment of women, or non-gender-relevant control information. Through a media preference survey, men then learned that their female partner disliked sexual content in films, after which they had an opportunity to send her up to 120?sec' worth of either a sexually explicit or nonsexual film clip. Validating the online sexual aggression paradigm, men with a 1-year history of sexual assault exhibited more sexually aggressive responding during the film selection paradigm. Moreover, exposure to injunctive norm information produced a boomerang effect, such that men high in hostile sexist attitudes showed an increase in sexual aggression when confronted with paternalism and gender equality norms. Conversely, exposure to paternalism and gender equality norms suppressed the otherwise protective function of high benevolent sexism in reducing men's sexually aggressive tendencies. The implications of these results for social norms interventions are discussed. Aggr. Behav. 41:580-593, 2015. © 2015 Wiley Periodicals, Inc. PMID:26174353

    The organisational culture, behavioural norms, and attitudes of a workplace have a profound influence on levels of injury and illness amongst its workers. While this is well established in Work Health and Safety literature, very little research has attempted to understand the influence of organisational culture on injury risk in the orchestral profession. To address this, the current study aimed to investigate the influence of organisational culture on injury outcomes for orchestral musicians. Using a qualitative case study methodology, in-depth semi-structured interviews were undertaken with 10 professional orchestral cellists (2 freelance and 8 fulltime members) from a single Australian orchestra. After initial data analysis, further interviews were undertaken with a set of 5 orchestral management staff as a means of data triangulation. All data were analysed using a themes-based "analysis of narrative" approach. The findings indicate that an orchestral culture exists in which musicians see injury as a sign of weakness, failure, and poor musicianship. Such negative perceptions of injury influence musicians to play through considerable levels of pain and continue performing with injuries. Because of perceived judgment from the orchestral group, musicians were found to conceal injuries from colleagues and management staff. Freelance musicians felt that disclosing injuries may lead to decreased work opportunities, and both full-time and casual musicians felt that "opening up" about injury may subject them to group judgment about their technique or musicianship. The study suggests education measures which may be effective at influencing individual behaviours and attitudes as well as cultural change initiatives which could lead to long-term positive health outcomes in the orchestral workplace.

    Mathematics has always become the most dislike subject among other subjects in school. Study showed that attitudes of students in science subjects such as mathematics were closely related to how they solve problems, accessing ideas and making a right decision. According to another study on mathematics achievement of eighth grade students in Malaysia, mathematics grades among bumiputera students was lower when compared to other races such as Chinese and Indians. The poor performance was due to their attitude and pre-conceived ideas towards the subject. Therefore, this study was designed todetermine the criteria and subcriteria that were considered important in measuring students' attitude toward mathematics among the bumiputeras. Factor analysis was carried out to identify the groups among criterion. Instrument used to measure mathematics attitude was Test of Mathematics Related Attitude (TOMRA) which measured student attitudes in four criteria: normality of mathematics, attitudes towards mathematics inquiry, adoption of mathematics attitude and enjoyment of mathematics lessons. The target population of this study was all computer science and quantitative science students who enrolled Calculus subject in UiTM Kedah. Findings shows that there are two criteria that influenced students attitude toward mathematics namely normality of mathematics with eleven subcriteria and enjoyment of mathematics with eight subcriteria. From the analysis it shows that the total percentage of variation explained is 35.071% with 0.837 Cronbach's alpha reliability test. The findings will help the lecturers, parents and society to consider what action should be taken to install interest and positive attitude of bumiputera students towards mathematics and thus improve their achievement.

    2012-01-01

    Few studies of the clergy have examined emotional well-being using normed measures. This study examined subjective well-being among 1,581 non-retired Episcopal priests. Subjective well-being was measured with the Positive and Negative Affect Schedule (Watson, Clark, & Tellegen, 1988) and the Satisfaction with Life Scale (Diener, Emmons, Larsen, & Griffin, 1985). Predictors of subjective well-being were measured with the Dispositional Hope Scale (Snyder et al., 1991) and scales of personal practices, social support, congregational dynamics, fit, and economic satisfaction. Participants reported more positive affect (Hedges's g = 1.19), more negative affect (Hedges's g = 0.61) and more satisfaction with life (Hedges's g = 0.73) than nonclinical norms. Hope agency was the strongest predictor for positive affect and satisfaction with life; stress was the strongest predictor for negative affect and partially mediated the effect of congregational dynamics and fit on this outcome. Results suggest that prevention programs must focus on all aspects of subjective well-being and consider the direct effects of different levels of the ecosystem to be effective. PMID:22694156

    Background Prolonged conflict in South Sudan exacerbated gender disparities and inequities. This study assessed differences in attitudes toward gender inequitable norms and practices by sex, age, and education to inform programming. Methods Applying community-based participatory research methodology, 680 adult respondents, selected by quota sampling, were interviewed in seven South Sudanese communities from 2009 to 2011. The verbally administered survey assessed attitudes using the Gender Equitable Men scale. Data were stratified by sex, age, and education. Results Of 680 respondents, 352 were female, 326 were male, and two did not report their sex. The majority of respondents agreed with gender inequitable household roles, but the majority disagreed with gender inequitable practices (i.e. early marriage, forced marriage, and inequitable education of girls). Respondents who reported no education were more likely than those who reported any education to agree with gender inequitable practices (all p<0.03) except for forced marriage (p=0.07), and few significant differences were observed when these responses were stratified by sex and age. Conclusion The study reveals agreement with gender inequitable norms in the household, but an overall disagreement with gender inequitable practices in sampled communities. The findings support that education of both women and men may promote gender equitable norms and practices. PMID:25026024

    Objective Since research that enrolls noncompetent patients with Alzheimers disease and does not present potential benefit to subjects is the source of substantial ethical controversy, we assessed willingness to have a proxy for research decision making, and, for each of two Alzheimers disease biomarker studies (minimal risk blood draw and a greater than minimal risk blood draw and lumbar puncture), willingness to grant an advance consent, and willingness to grant a proxy leeway over advance consent. Methods Face to face survey of 538 persons 65 and over who resided in the Southeastern Pennsylvania region Results The majority 83% (445/538) granted advance consent to a blood draw study and nearly half to a blood draw plus lumbar puncture 259 (48%). Most persons (96%) were willing to identify a proxy for research decision making and most were willing to grant their proxy leeway over their advance consent: blood draw 434 (81%), and 375 (70%) blood draw plus lumbar puncture. Combining the preferences for advance consent and leeway, the proportion who would permit being enrolled in the blood draw and spinal fluid sample studies were, respectively, 92% (497/538) and 75% (404/538). Multi-variate models showed that willingness to be enrolled in research was most strongly associated with a favorable attitude about biomedical research. Conclusions Older adults generally support enrolling noncompetent persons with Alzheimers disease into research that does not present a benefit to subjects. Willingness to grant their proxy leeway over advance consent and a favorable attitude about biomedical research substantially explain this willingness. PMID:18923066

    Brysbaert, Marc; Cortese, Michael J

    2011-03-01

    Megastudies with processing efficiency measures for thousands of words allow researchers to assess the quality of the word features they are using. In this article, we analyse reading aloud and lexical decision reaction times and accuracy rates for 2,336 words to assess the influence of subjective frequency and age of acquisition on performance. Specifically, we compare newly presented word frequency measures with the existing frequency norms of Kucera and Francis (1967), HAL (Burgess & Livesay, 1998), Brysbaert and New (2009), and Zeno, Ivens, Millard, and Duvvuri (1995). We show that the use of the Kucera and Francis word frequency measure accounts for much less variance than the other word frequencies, which leaves more variance to be "explained" by familiarity ratings and age-of-acquisition ratings. We argue that subjective frequency ratings are no longer needed if researchers have good objective word frequency counts. The effect of age of acquisition remains significant and has an effect size that is of practical relevance, although it is substantially smaller than that of the first phoneme in naming and the objective word frequency in lexical decision. Thus, our results suggest that models of word processing need to utilize these recently developed frequency estimates during training or setting baseline activation levels in the lexicon.

Data from the International Tobacco Control Project (N = 13,062) revealed that higher odds of intending to quit were associated with negative personal attitudes in Thailand and the Western countries, but not in Malaysia; with norms against smoking from significant others in Malaysia and the Western countries, but not in Thailand; and with societal norms against smoking in all countries. Our findings indicate that normative factors are important determinants of intentions, but they play a different role in different cultural and/or tobacco control contexts. Interventions may be more effective if they are designed with these different patterns of social influence in mind. PMID:20186642

    How do scientists react when the institutional setting in which they conduct their work changes radically? How do long-standing norms regarding the social responsibility of scientists fare? What factors influence whether scientists embrace or reject the new institutions and norms? We examine these questions using data from a unique survey of 602 scientists in Russia, whose science system experienced a sustained crisis and sweeping changes in science institutions following the collapse of the Soviet Union. We develop measures of how respondents view financing based on grants and other institutional changes in the Russian science system, as well as measures of two norms regarding scientists social responsibility. We find that the majority of scientists have adapted, in the sense that they hold positive views of the new institutions, but a diversity of orientations remains. Social responsibility norms are common among Russian scientists, but far from universal. The main correlates of adaptation are age and current success at negotiating the new institutions, though prospective success, work context, and ethnicity have some of the hypothesized associations. As for social responsibility norms, the main source of variation is age: younger scientists are more likely to embrace individualistic rather than socially-oriented norms.

    In recent years, the use of learning management system by universities has been increasingly growing. However, the results of several studies have revealed that students do not fully use the information systems. The present study proposes a model which investigates the influence of three constructs of perceived ease of use, perceived usefulness, and subjective norm on behavior intention to use of learning management system. The sample size was 216 Malaysian undergraduate students. The results of the study revealed that the proposed model accounts for 31.1 % variance of behavior intention to use.

    2010-01-01

    This study of mother–adult daughter communication uses qualitative methods to explore the appropriateness of including adult daughters as referents in the measurement of subjective norms (a behavioral theory construct) related to the use of mammography and other health-related tests and services. The methods were chosen to approximate as closely as possible the mother–adult daughter relationship in the context of daily life. This inductive approach contrasts with the deductive origins of the construct. A sample of nine Mexican and Filipina immigrant and U.S.-born mothers and their adult daughters was recruited. Data were collected in two phases: (a) videotaped observations of mother–daughter dyads discussing health-related topics and (b) follow-up interviews designed to obtain an emic (insider) perspective of the videotaped interaction. Results show that adult daughters influence their mothers’ ability to navigate the health care system and contribute to health-related decision making and behavior, suggesting that it may be appropriate to include adult daughters in the assessment of subjective norms.

  2. An assessment of attitudes toward gender inequitable sexual and reproductive health norms in South Sudan: a community-based participatory research approach

    PubMed Central

    2013-01-01

    Background Communities in South Sudan have endured decades of conflict. Protracted conflict exacerbated reproductive health disparities and gender inequities. This study, conducted prior to the country’s 2011 independence, aimed to assess attitudes toward gender inequitable norms related to sexual relationships and reproductive health and the effects of sex, age, and education on these attitudes. Methods Applying a community-based participatory research approach and quota sampling, 680 adult male and female respondents were interviewed in seven sites within South Sudan in 2009–2011. The verbally administered survey assessed attitudes using the Gender Equitable Men scale. Data were stratified by sex, age (?35 years and >35 years), and education. Results Of 680 respondents, 352 were female, 326 were male, and 2 did not indicate their sex. The majority of women (77%) and men (74%) agreed “a man needs other women, even if things with his wife are fine”. Respondents who reported no education (60%) were more likely than those who reported any education (45%) to agree “if a woman is married, she should have sex with her husband whenever he wants to, even if she doesn’t want to” (p?=?0.002). The majority of women (74%) and men (73%) agreed “it is a woman’s responsibility to avoid getting pregnant”. Respondents who reported no education (81%) were more likely than those who reported any education (72%) to agree with this statement (p?=?0.04). When asked about condom use, the majority of respondents, across both sexes and both age groups, agreed “it would be outrageous for a wife to ask her husband to use a condom” and “women who carry condoms are easy”. There were no statistically significant differences between the two age groups for any of the assessed gender inequitable norms. Conclusion The study reveals differences in attitudes toward gender inequitable sexual and reproductive health norms among those surveyed in South Sudan when stratified by sex and education. As a new nation seeks to strengthen its health system, these data can inform sexual and reproductive health policies and programming in South Sudan. PMID:24209789

    2013-01-01

    The young urban population of Tanzania is growing rapidly, primarily due to rural-urban migration. More information is needed on the challenges facing young adult urban women and men in using family planning (FP). The purpose of this study is to identify perceptions, interpersonal and familial attitudes, and sociocultural norms regarding FP among young adults (18-25 years) in Dar es Salaam, Tanzania, comparing responses by sex, marital status and migration status. We conducted 12 focus groups with young adult men and women (n=74) in Dar es Salaam in December 2009. Participants knew of modern contraceptive methods, but had serious concerns about side effects. Single men and women preferred condoms. Female migrants stated that traditional methods were ineffective, yet commonly used in rural areas. Men's desires for more children frequently led female migrants not to use FP, while many married long-term residents used FP discreetly. Single women sometimes received the support of their parents/boyfriends to access and use contraception. Findings highlight differences in experiences among young adult men and women based on their migrant and marital status at the individual, interpersonal and normative levels. Future efforts to promote FP should engage existing social support systems and cultivate new ones in response to barriers. PMID:24156247

    Objective. This study aimed to investigate the impact of subject age, gender, and arch length on dentists' attitudes towards unrestored shortened dental arches. Materials and Methods. 93 Syrian dentists were interviewed and presented with 24 scenarios for male and female subjects of different ages and shortened dental arches of varying length. Participants were asked to indicate on a standardized visual analogue scale how they would value the health of the mouth if the posterior space was left unrestored. Results. A value of 0.0 represented the worst possible health state for a mouth and 1.0 represented the best. The highest mean value (0.73) was assigned to a shortened dental arch with missing second molar teeth in the mouth of a 70-year-old subject. A 35-year-old female subject with an extremely shortened dental arch (all molar and premolar teeth are missing) attracted the lowest mean value (0.26). The statistical analysis indicated a significant decrease in the value placed on unrestored shortened dental arches as the number of remaining teeth decreased (p < 0.008). While subject gender had almost no impact on dentists' attitudes towards shortened dental arches, the scenarios for the older shortened dental arch subjects attracted significantly higher values compared to the scenarios for the younger subjects (p < 0.017). Conclusion. Subject age and arch length affect dentists' attitudes towards shortened dental arches, but subject gender does not. PMID:26265916

  9. Adaptation and perceptual norms

    Webster, Michael A.; Yasuda, Maiko; Haber, Sara; Leonard, Deanne; Ballardini, Nicole

    2007-02-01

    We used adaptation to examine the relationship between perceptual norms--the stimuli observers describe as psychologically neutral, and response norms--the stimulus levels that leave visual sensitivity in a neutral or balanced state. Adapting to stimuli on opposite sides of a neutral point (e.g. redder or greener than white) biases appearance in opposite ways. Thus the adapting stimulus can be titrated to find the unique adapting level that does not bias appearance. We compared these response norms to subjectively defined neutral points both within the same observer (at different retinal eccentricities) and between observers. These comparisons were made for visual judgments of color, image focus, and human faces, stimuli that are very different and may depend on very different levels of processing, yet which share the property that for each there is a well defined and perceptually salient norm. In each case the adaptation aftereffects were consistent with an underlying sensitivity basis for the perceptual norm. Specifically, response norms were similar to and thus covaried with the perceptual norm, and under common adaptation differences between subjectively defined norms were reduced. These results are consistent with models of norm-based codes and suggest that these codes underlie an important link between visual coding and visual experience.

    This study investigated mind-wandering (MW) in children during a laboratory task, and explored the influence of children's attitudes towards MW on the accuracy of their subjective reports. Children's MW experiences were probed during the adapted Sustained-Attention-to-Response-Task (SART), and their attitudes was measured by a questionnaire, according to which children were divided into positive or negative group. Results showed that (1) MW in children was basically identical to MW in adults which was associated with poor performance, increased behavioural variability, and a prospective bias; (2) reliable correlations between behavioural correlates and MW frequency were observed in negative group, but not in positive group; and (3) positive group reported more MW than negative group, while no behavioural correlate was significantly different between the two groups. We concluded that (1) overall, children could accurately introspect their MW experiences during SART; and (2) children with positive attitudes provided invalid subjective reports of MW.

    1994-12-31

    In this talk we will present a success story of using barrier methods for a large scale non-smooth non-linear convex programming problem. The problem of concern is minimizing a sum of Euclidean norms subject to linear equality constraints (MSN). We will present the duality theory for this problem. This theory is important for the development of an efficient barrier method. We will describe such an algorithm based on the Newton barrier method proposed by K.D. Andersen 1993 for minimizing a sum of norms MSN. The linear equality constraints are handled using an exact Ll penalty function, which is smoothed in the same way as the euclidean norms. Numerical results are presented for large sparse problems arising in plastic collapse analysis. Some of the test problems have been linearized, and interior point LP methods have been used to solve them. A comparison is carried out between the presented method and LP methods for these problems. The results show that the MSN method is not only faster but it also use less memory.

  13. Teaching hands-on science activities: Variables that moderate attitude-behavior consistency

    Koballa, Thomas R., Jr.

    The relationship between prospective elementary teachers' attitudes, subjective norms, and intentions to teach science using hands-on activities at least twice a week during their first year of employment was investigated. The findings suggest that measuring prospective teachers' attitudes toward science cannot adequately predict nor provide a satisfactory explanation of their science teaching behaviors. The findings also provide clear support for two hypotheses derived from Fishbein and Ajzen's theory of reasoned action regarding the predictability of prospective teachers' intentions to teach science from their attitudes and subjective norms.Received: 25 October 1985

    2013-01-01

    Objectives: The acceptance and use of long-acting depot antipsychotics has been shown to be influenced by the attitudes of patients and clinicians. Depot treatment rates are low across countries and especially patients with first-episode psychosis are rarely treated with depot medication. The aim of this article was to review the literature on patients’ and clinicians’ attitudes towards long-acting depot antipsychotics in subjects with first-episode psychosis. Methods: A systematic search of Medline, Embase, PsycINF and Google Scholar was conducted. Studies were included if they reported original data describing patients’ and clinicians’ attitudes towards long-acting depot antipsychotic in subjects with first-episode psychosis. Results: Six studies out of a total of 503 articles met the inclusion criteria. Four studies conveyed a negative and two a positive opinion of clinicians toward depot medication. No systematic study directly addressed the attitude of patients with first-episode psychosis. Psychiatrists frequently presume that patients with first-episode psychosis would not accept depot medication and that depots are mostly eligible for chronic patients. Conclusions: Full information of all patients especially those with first episode psychosis in a therapeutic relationship that includes shared decision-making processes could reduce the negative image and stigmatization attached to depots.

  16. The control of space manipulators subject to spacecraft attitude control saturation limits

    NASA Technical Reports Server (NTRS)

    Dubowsky, S.; Vance, E. E.; Torres, M. A.

    1989-01-01

    The motions of robotic manipulators mounted on spacecraft can disturb the spacecraft's positions and attitude. These disturbances can surpass the ability of the system's attitude control reaction jets to control them, for the disturbances increase as manipulator speeds increase. If the manipulator moves too quickly the resulting disturbances can exceed the saturation levels of the reaction jets, causing excessive spacecraft motions. A method for planning space manipulator's motions is presented, so that tasks can be performed as quickly as possible without saturating the system's attitude control jets.

    2004-03-01

    The Hamiltonian equations of a liquid-filled satellite subject to gravity-gradient torques in terms of the generalized Deprit variables are established for applying the Melnikov theory formally. The heteroclinic orbits of the torque-free symmetric liquid-filled satellite are found. A criterion for the heteroclinic transversal intersections at the onset of chaotic attitude is formulated using Melnikov's integral. The results from the Melnikov theory are crosschecked with simulation. PMID:15003050

    2014-01-01

    The present research adopts an extended theory of the planned behavior model that included descriptive norms, risk, and trust to investigate online privacy protection in Facebook users. Facebook users (N = 119) completed a questionnaire assessing their attitude, subjective injunctive norm, subjective descriptive norm, perceived behavioral control, implicit perceived risk, trust of other Facebook users, and intentions toward protecting their privacy online. Behavior was measured indirectly 2 weeks after the study. The data show partial support for the theory of planned behavior and strong support for the independence of subjective injunctive and descriptive norms. Risk also uniquely predicted intentions over and above the theory of planned behavior, but there were no unique effects of trust on intentions, nor of risk or trust on behavior. Implications are discussed. PMID:25154118

    2015-09-01

    We examined whether internalization of sociocultural body ideals mediated the relationship between conformity to masculine norms and drive for muscularity, leanness, and thinness in a sample of males from Sweden, US, UK, and Australia. Over six hundred young men [n=142 (Sweden); n=192 (US); n=141 (UK); n=160 (Australia)] completed an online survey that included assessments of masculine role norms, body image, and internalization of sociocultural body ideals. Path analyses confirmed internalization as a mediator between greater conformity to masculine norms and body image measures (drive for thinness, desire for leanness, and desire for muscularity) across the sample. However, significant cross-country differences in the strength of these mediation effects were found. Mediation effects among US, Australian, and Swedish males were comparable, whereas these effects were weaker in the UK sample. Findings confirmed the importance of internalization of sociocultural body ideals in the tested models. PMID:26160708

    Our research analyzes the effect of the traders’ subjective risk attitude, optimism and overconfidence on their risk taking behaviors on the Chinese Stock Market by experimental study method. We find that investors’ risk taking behavior is significantly affected by their subjective risk attitude, optimism and overconfidence. Our results also argue that the objective return and volatility of stock are not as good predictors of risk taking behavior as subjective risk and return measures. Moreover, we illustrate that overconfidence and optimism have an significant impact on risk taking behavior In line with theoretical models.

    Providing people with information about the behavior and attitudes of their peers is a strategy commonly employed by those seeking to reduce behavior deemed harmful either to individuals (e.g., high alcohol consumption) or the collective (e.g., high energy consumption). We review norm-based interventions, detailing the logic behind them and the various forms they can take. We give special attention to interventions designed to decrease college students' drinking and increase environment-friendly behaviors. We identify the conditions under which norm information has the highest likelihood of changing the targeted behavior and discuss why this is the case. PMID:26253542

    Sexual prejudice and antigay anger were examined as mediators of the associations between traditional male gender norms, religious fundamentalism, and aggression toward gay men and lesbians. Participants were 201 self-identified heterosexual men recruited from the community to complete computer-administered measures of adherence to traditional male gender norms (i.e., status, toughness, antifemininity), religious fundamentalism, sexual prejudice, and frequency of aggression toward gay men and lesbians. Additionally, participants completed a structured interview designed to assess anger in response to a vignette depicting a male-male intimate relationship (i.e., partners saying “I love you,” holding hands, kissing). Results showed that sexual prejudice and antigay anger partially mediated the effect of antifemininity on aggression and fully mediated the effect of religious fundamentalism on aggression. Sexual prejudice alone fully mediated the effect of status on aggression and neither sexual prejudice nor antigay anger mediated the effect of toughness on aggression. Further, results suggested that religious fundamentalism is a multifaceted construct of which some aspects increase risk for aggression toward gay men and lesbians, whereas other aspects decrease this risk. These data provide multivariate evidence from a nonprobability, community-based sample that extreme internalization of dominant cultural values can set the stage for violence toward marginalized groups. Implications for intervention programming and future research are reviewed. PMID:22081759

    2001-01-01

    The four-component quaternion has the lowest dimensionality possible for a globally nonsingular attitude representation, it represents the attitude matrix as a homogeneous quadratic function, and its dynamic propagation equation is bilinear in the quaternion and the angular velocity. The quaternion is required to obey a unit norm constraint, though, so Kalman filters often employ a quaternion for the global attitude estimate and a three-component representation for small errors about the estimate. We consider these mixed attitude representations for both a first-order Extended Kalman filter and a second-order filter, as well for quaternion-norm-preserving attitude propagation.

    Research has demonstrated the environmentally conscious behavior of parents and caregivers acts as a social influence that produces environmentally conscious behavior in their children, and also has an effect on their children's cost-benefit evaluations and social norm evaluations. The present study examined the personal norms for producing continuous environmentally conscious behavior, and two social norms that form the personal norms, which are categorized as descriptive and subjective norms. The results of this study suggest that the subjective norm formed the personal norm. Furthermore, the parents' normative social influences affected the personal norm through the subjective norm, and the parents' behavior affected their children's environmentally conscious behavior through the descriptive norm.

    A measure of subjective social status (SSS) was examined among high (White), and low (Black and Roma) ethnic status children in Portugal within a developmental design including 6-8-year-old and 9-12-year-old children. White children favoured their in-group over the Black and Roma out-groups on the SSS measure, social preferences and positive as well as negative trait attributions. Generally, the Black and Roma showed equal SSS, preferences and trait attribution for their in-group and the high status White out-group, but not the other low-status out-group. With age White children generally demonstrated higher SSS for Black and Roma, preferred them more and attributed more positive traits. For low-status groups, an age effect was found only for Black children who preferred the Roma more with age and attributed more positive traits. Changes on preferences and trait attribution depending on age-group were mediated by SSS. It is concluded that minority group's SSS does not parallel the objective status hierarchy but, rather, is a dynamic reorganisation of group's relative positions serving strategies to cope with their minority condition.

  17. Values, attitudes and perceptions of managers as predictors of corporate environmental responsiveness.

    PubMed

    Papagiannakis, Giorgos; Lioukas, Spyros

    2012-06-15

    We examine whether managers' values, attitudes, and perceptions influence the greening of organizations. To that purpose, we specify and test a model of corporate environmental responsiveness (CER), drawing upon a modified version of the theory of planned behavior and the value-belief-norm theory. Based on survey data from 142 Greek companies, we find that top managers' personal values influence responses indirectly, through shaping their environmental attitudes, while direct relationship is not significant. Subjective norms, expressing stakeholder expectations, do affect CER, with their effect being stronger than that of attitudes. Managers' perceived ability to handle environmental issues also appears to influence responses. Results have theoretical implications, indicating the significant role of managers' values, attitudes and perceptions in a firm's environmental response. Practical implications are discussed in relation to selection of managers and training. PMID:22361109

  18. The Effects of Mentored Problem-Based STEM Teaching on Pre-Service Elementary Teachers: Scientific Reasoning and Attitudes Toward STEM Subjects

    Caliendo, Julia C.

    Problem-based learning in clinical practice has become an integral part of many professional preparation programs. This quasi-experimental study compared the effect of a specialized 90-hour field placement on elementary pre-service teachers' scientific reasoning and attitudes towards teaching STEM (science, technology, engineering, and math) subjects. A cohort of 53 undergraduate elementary education majors, concurrent to their enrollment in science and math methods classes, were placed into one of two clinical practice experiences: (a) a university-based, problem-based learning (PBL), STEM classroom, or (b) a traditional public school classroom. Group gain scores on the Classroom Test of Scientific Reasoning (CTSR) and the Teacher Efficacy and Attitudes Toward STEM Survey-Elementary Teachers (T-STEM) survey were calculated. A MANCOVA revealed that there was a significant difference in gain scores between the treatment and comparison groups' scientific reasoning (p = .011) and attitudes towards teaching STEM subjects (p = .004). The results support the hypothesis that the pre-service elementary teachers who experienced STEM mentoring in a PBL setting will have an increase in their scientific reasoning and produce positive attitudes towards teaching STEM subjects. In addition, the results add to the existing research suggesting that elementary pre-service teachers require significant academic preparation and mentored support in STEM content.

    Many countries, Sweden among them, lack professional guidelines and established procedures for responding to young females requesting virginity certificates or hymen restoration due to honour-related threats. The purpose of the present survey study was to further examine the attitudes of the Swedish healthcare professionals concerned towards young females requesting virginity certificates or hymen restorations. The study indicates that a small majority of Swedish general practitioners and gynaecologists would accommodate these patients, at least given certain circumstances. But a large minority of physicians would under no circumstances help the young females, regardless of speciality, years of practice within medicine, gender, or experience of the phenomenon. Their responses are similar to other areas where it has been claimed that society should adopt a zero tolerance policy against certain phenomena, for instance drug policy, where it has also been argued that society should never act in ways that express support for the practice in question. However, this argument is questionable. A more pragmatic approach would also allow for follow-ups and evaluation of virginity certificates and hymen restorations, as is demonstrated by the Dutch policy. Hence, there are some obvious advantages to this pragmatic approach compared to the restrictive one espoused by a large minority of Swedish physicians and Swedish policy-makers in this area.

    Secondary prevention of harm from sport-related concussion is contingent on immediate removal from play post-injury. To-date, educational efforts to reduce the prevalent risk behavior of continued play while symptomatic have been largely ineffective. Social norms theory may hold promise as a foundation for more effective concussion education aimed at increasing concussion reporting. The primary objective of this study was to assess whether perceived team concussion reporting norms would be less supportive of an individual's safe concussion symptom reporting behavior than objective team norms. Participants were 328 male and female US collegiate athletes. Written surveys were completed in person during the spring of 2014. Among both male and female athletes, team concussion reporting norms were significantly misperceived, with athletes tending to think that they themselves have safer attitudes about concussion reporting than their teammates. Perceived norms were associated with symptom reporting intention, independent of the team's objective reporting norm. A social norms approach to concussion education, in which misperceived group norms are corrected and shifted in the direction of safety, is an important avenue for program development and evaluation research aimed at the secondary prevention of harm from concussion. Implications for the design of this type of educational programming are discussed. PMID:26471918

  3. Development, social norms, and assignment to task

    2011-01-01

    Economic development involves a structural transformation in the way people are allocated to tasks. There is a shift from self-provision to market exchange, facilitating specialization. There is also a shift from self-employment to wage employment in large firms and organizations, driven by innovation and increasing returns to scale. Changes in allocation mechanisms require changes in norms and attitudes. Because different labor assignment domains coexist, conflicts arise among norms that apply to different domains, possibly resulting in dysfunctional outcomes. I argue that religion, humanism, and schools have all played an important historical role in fostering the changes in social norms and attitudes that are needed to accompany structural changes in the way economies allocate workers to tasks.

    NASA Astrophysics Data System (ADS)

    Conte, Rosaria; Andrighetto, Giulia; Villatoro, Daniel

    In this presentation, advances in modeling the mental dynamics of norms will be presented. In particular, the process from norm-adoption, possibly yielding new normative goals, to different forms of norm compliance will be focused upon, including norm internalization, which is at study in social-behavioral sciences and moral philosophy since long. Of late, the debate was revamped within the rationality approach pointing to the role of norm internalization as a less costly and more reliable enforcement system than social control. So far, poor attention was paid to the mental underpinnings of internalization. In this presentation, a rich cognitive model of different types, degrees and factors of internalization is shown. The initial implementation of this model on EMIL-A, a normative agent architecture developed and applied to the.

    The quaternion has the lowest dimensionality possible for a globally nonsingular attitude representation. The quaternion must obey a unit norm constraint, though, which has led to the development of an extended Kalman filter using a quaternion for the global attitude estimate and a three-component representation for attitude errors. We consider various attitude error representations for this Multiplicative Extended Kalman Filter and its second-order extension.

    Consistent with the global trend to shift responsibility for retirement income provision from the public purse to individuals has been encouragement to save more and to manage investment strategy. Analyzing data from 2,300 respondents to a randomly distributed questionnaire, this article focuses on the motivational importance of social norms. The study finds injunctive social norms (what is commonly approved or disapproved of) exert greater influence than descriptive social norms (what is commonly done) in predicting retirement savings intentions. Modeling employs the theory of planned behavior, and also finds injunctive social norm has predictive primacy over attitude and perceived behavioral control. Discussion advocates a balanced approach to intervention design, and identifies opportunities for the further study of normative message framing. PMID:21261135

  14. Parent-Adolescent Sexual and Reproductive Health Communication Is Very Limited and Associated with Adolescent Poor Behavioral Beliefs and Subjective Norms: Evidence from a Community Based Cross-Sectional Study in Eastern Ethiopia

    PubMed Central

    2015-01-01

    Introduction While parent-adolescent sexual and reproductive health (SRH) communication is one potential source of SRH information for adolescents, it appears to be inadequately practiced in Ethiopia. This study was designed to investigate the factors that limit or improve parent-adolescent SRH communication in Harar, Eastern Ethiopia. Methods A community based cross-sectional study was done on 4,559 adolescents of age 13–18. SRH communication was measured using a nine-item scale whose response ranged from “not at all” to “always.” Summated composite score ranging from 0–36 was generated; higher score indicates high SRH communication. A median value of the composite score was 4 out of the possible 36 with an Interquartile Range (IQR) of 7. Respondents were ranked as very poor, poor and satisfactory communicators based on 33rd and 67th percentiles values. Generalized ordered logit model was applied to investigate the factors associated with SRH communication. Results Results showed that the adolescents who were more likely to practice poor-very poor/very poor SRH communication were those who had poor behavioral beliefs on and poor subjective norms of communicating sexual issues with parents and those who perceived their parents’ reproductive health (RH) knowledge as poor. Nonetheless, the probability of poor-very poor/very poor SRH communication was less with high adolescent-parent communication quality, television co-viewing and discussions, and self-disclosure. Conclusions Curtailing the adolescents’ underlying poor beliefs and norms, and improving adolescent-parent communication quality, self-disclosure, and television co-viewing and discussions are essential to engage the parents in sexual and reproductive health education of the adolescents.

    We consider four norms on tensor product spaces that have appeared in quantum information theory and demonstrate duality relationships between them. We show that the product numerical radius is dual to the robustness of entanglement, and we similarly show that the S(k)-norm is dual to the projective tensor norm. We show that, analogous to how the product numerical radius and the S(k)-norm characterize k-block positivity of operators, there is a natural version of the projective tensor norm that characterizes Schmidt number. In this way we obtain an elementary new proof of the cross norm criterion for separability, and we also generalize both the cross norm and realignment criteria to the case of arbitrary Schmidt number.

  16. A Review of Norms and Normative Multiagent Systems

    PubMed Central

    Mahmoud, Moamin A.; Ahmad, Mohd Sharifuddin; Mustapha, Aida

    2014-01-01

    Norms and normative multiagent systems have become the subjects of interest for many researchers. Such interest is caused by the need for agents to exploit the norms in enhancing their performance in a community. The term norm is used to characterize the behaviours of community members. The concept of normative multiagent systems is used to facilitate collaboration and coordination among social groups of agents. Many researches have been conducted on norms that investigate the fundamental concepts, definitions, classification, and types of norms and normative multiagent systems including normative architectures and normative processes. However, very few researches have been found to comprehensively study and analyze the literature in advancing the current state of norms and normative multiagent systems. Consequently, this paper attempts to present the current state of research on norms and normative multiagent systems and propose a norm's life cycle model based on the review of the literature. Subsequently, this paper highlights the significant areas for future work. PMID:25110739

    The authors examined same- and cross-gender friendship norms in a sample of 135 adults (average age 73 years). Participants evaluated a friend’s behavior, quantitatively and qualitatively, in vignettes in which the friend’s gender was experimentally manipulated. Gender often significantly, though modestly, influenced normative evaluations. Women frequently had higher expectations of friends than men and placed a greater emphasis on intimacy. Women were more disapproving of violations of friendship rules, such as betraying a confidence, paying a surprise visit, and failing to stand up for a friend in public. However, both men and women were less approving of a man than a woman who greets another friend with a kiss or who requests to stay overnight. Respondents’ open-ended comments reflected positive attitudes regarding cross-gender friendships. Most findings demonstrated that men and women across a wide age range held similar cultural norms for close ties, norms of trust, commitment, and respect. PMID:20473364

    The purpose of this study is to advance theorizing about how small groups understand health issues through the use of social network analysis. To achieve this goal, an adapted cognitive social structure examines group social norms around a specific health issue, H1N1 flu prevention. As predicted, individual’s attitudes, self-efficacy, and perceived social norms were each positively associated with behavioral intentions for at least one of the H1N1 health behaviors studied. Moreover, collective norms of the whole group were also associated with behavioral intentions, even after controlling for how individual group members perceive those norms. For members of work groups in which pairs were perceived to agree in their support for H1N1 vaccination, the effect of individually perceived group norms on behavioral intentions was stronger than for groups with less agreement.

  4. The effect of video interviews with STEM professionals on STEM-subject attitude and STEM-career interest of middle school students in conservative Protestant Christian schools

    NASA Astrophysics Data System (ADS)

    Alsup, Philip R.

    Inspiring learners toward career options available in STEM fields (Science, Technology, Engineering, and Mathematics) is important not only for economic development but also for maintaining creative thinking and innovation. Limited amounts of research in STEM education have focused on the population of students enrolled in religious and parochial schools, and given the historic conflict between religion and science, this sector of American education is worthy of examination. The purpose of this quantitative study is to extend Gottfredson's (1981) Theory of Circumscription and Compromise as it relates to occupational aspirations. Bem's (1981) Gender Schema Theory is examined as it relates to the role of gender in career expectations, and Crenshaw's (1989) Intersectionality Theory is included as it pertains to religion as a group identifier. Six professionals in STEM career fields were video recorded while being interviewed about their skills and education as well as positive and negative aspects of their jobs. The interviews were compiled into a 25-minute video for the purpose of increasing understanding of STEM careers among middle school viewers. The research questions asked whether middle school students from conservative, Protestant Christian schools in a Midwest region increased in STEM-subject attitude and STEM-career interest as a result of viewing the video and whether gender interacted with exposure to the video. A quasi-experimental, nonequivalent control groups, pretest/posttest factorial design was employed to evaluate data collected from the STEM Semantic Survey. A Two-Way ANCOVA revealed no significant differences in dependent variables from pretest to posttest. Implications of the findings are examined and recommendations for future research are made. Descriptors: STEM career interest, STEM attitude, STEM gender disparity, Occupational aspirations, Conservative Protestant education.

    1998-01-01

    OBJECTIVES: This study was designed to identify and compare the attitudes of patients and health care professionals towards advance directives. Advance directives promote recognition of the patient's autonomy, letting the individual exercise a certain measure of control over life-sustaining care and treatment in the eventuality of becoming incompetent. DESIGN: Attitudes to advance directives were evaluated using a 44-item self-reported questionnaire. It yields an overall score as well as five factor scores: autonomy, beneficence, justice, external norms, and the affective dimension. SETTING: Health care institutions in the province of Québec, Canada. Survey sample: The sampling consisted of 921 subjects: 123 patients, 167 physicians, 340 nurses and 291 administrators of health care institutions. RESULTS: Although the general attitude of each population was favourable to the expression of autonomy, multivariate analysis of variance (MANOVA) indicated that physicians attached less importance to this subscale than did other populations (p < .001). Above all, they favoured legal external norms and beneficence. Physicians and administrators also attached less importance to the affective dimension than did patients and nurses. Specifically, physicians' attitudes towards advance directives were shown to be less positive than patients' attitudes. CONCLUSION: More attention should be given to the importance of adequately informing patients about advance directives because they may not represent an adequate means for patients to assert their autonomy.

    2014-01-01

    This work investigates the use of mixed-norm regularization for sensor selection in event-related potential (ERP) based brain-computer interfaces (BCI). The classification problem is cast as a discriminative optimization framework where sensor selection is induced through the use of mixed-norms. This framework is extended to the multitask learning situation where several similar classification tasks related to different subjects are learned simultaneously. In this case, multitask learning helps in leveraging data scarcity issue yielding to more robust classifiers. For this purpose, we have introduced a regularizer that induces both sensor selection and classifier similarities. The different regularization approaches are compared on three ERP datasets showing the interest of mixed-norm regularization in terms of sensor selection. The multitask approaches are evaluated when a small number of learning examples are available yielding to significant performance improvements especially for subjects performing poorly.

    1990-01-01

    An approximate knowledge of the torque equilibrium attitude (TEA) is shown to improve the performance of a control moment gyroscope (CMG) momentum management/attitude control law for Space Station Freedom. The linearized equations of motion are used in conjunction with a state transformation to obtain a control law which uses full state feedback and the predicted TEA to minimize both attitude excursions and CMG peak and secular momentum. The TEA can be computationally determined either by observing the steady state attitude of a 'controlled' spacecraft using arbitrary initial attitude, or by simulating a fixed attitude spacecraft flying in desired orbit subject to realistic environmental disturbance models.

    1997-01-01

    Theories related to planned behavior and reasoned action have included an individual's attitude as an important factor in the formation of behavioral intentions and behaviors. Research on this topic suggests that salient beliefs affect intentions and subsequent behaviors, either through attitudes or subjective norms, or the degree of (perceived) control that an individual feels he/she has over the behavior. This study was designed to examine the relative importance of selected attitude variables in describing a profile of athletes who were at risk for using anabolic steroids, human grown hormone, amphetamines, cocaine, and marijuana. Responses from 563 student athletes at two Division One NCAA universities were used in the study. The results of this study suggest that subjective norms, based on the influence of drug testing, peer influence, and a fear of detection are significant factors that influence the decisions of student athletes related to using banned substances. In this article characteristics of at-risk athletes are presented with recommendations for drug education programs for student athletes. PMID:9270209

  16. Graph-Based Norm Explanation

    NASA Astrophysics Data System (ADS)

    Croitoru, Madalina; Oren, Nir; Miles, Simon; Luck, Michael

    Norms impose obligations, permissions and prohibitions on individual agents operating as part of an organisation. Typically, the purpose of such norms is to ensure that an organisation acts in some socially (or mutually) beneficial manner, possibly at the expense of individual agent utility. In this context, agents are normaware if they are able to reason about which norms are applicable to them, and to decide whether to comply with or ignore them. While much work has focused on the creation of norm-aware agents, much less has been concerned with aiding system designers in understanding the effects of norms on a system. The ability to understand such norm effects can aid the designer in avoiding incorrect norm specification, eliminating redundant norms and reducing normative conflict. In this paper, we address the problem of norm understanding by providing explanations as to why a norm is applicable, violated, or in some other state. We make use of conceptual graph based semantics to provide a graphical representation of the norms within a system. Given knowledge of the current and historical state of the system, such a representation allows for explanation of the state of norms, showing for example why they may have been activated or violated.

    BACKGROUND: Obesity and over weight is one of the causes of threatening children's present and future life. One of the factors that cause this problem is parents’ attitude toward preschool children's nutritional patterns. Education can improve the parents’ attitude and prevents from this big issue. This study aimed to assess changes in mother's attitude and behavioral intention using intention model. METHODS: This was a semi-experimental study with pre-test, post test design. Forty-five mothers with overweight preschool children attended this study. Sampling was based on cluster randomize sampling method. The researcher-made questionnaire which was used in this study was standardized through content validity and test, re-test. RESULTS: Comparing the pretest and posttest scores indicated a statistically significant difference in the attitude mean score. The findings of this study suggest that attitude and behavioral intention about nutritional patterns can be improved through parents’ education based on behavioral intention model such as attitude, subjective norm and behavioral intention. CONCLUSIONS: In order to have healthy children, parents should improve their knowledge about how they promote their attitude towards children's nutritional pattern. Therefore, new model of education can optimize correct healthy behavior. PMID:22069415

    2014-10-01

    Working environments that are both civil and safe are good for business and employee well-being. Civility has been empirically linked to such important outcomes as organizational performance and individuals' positive work-related attitudes, yet research relating civility to safety is lacking. In this study, we link perceptions of civility norms to perceptions of safety climate and safety outcomes. Drawing on social exchange theory, we proposed and tested a model in 2 samples wherein civility norms indirectly relate to safety outcomes through associations with various safety climate facets. Our results supported direct relationships between civility and management safety climate and coworker safety climate. Additionally, indirect effects of civility norms on unsafe behaviors and injuries were observed. Indirect effects of civility norms on unsafe behaviors were observed through coworker safety climate and work-safety tension. Indirect effects of civility norms on injuries were observed through management safety climate and work-safety tension for full-time employees, although these effects did not hold for part-time employees. This study provides initial evidence that researchers and practitioners may want to look beyond safety climate to civility norms to more comprehensively understand the origins of unsafe behaviors and injuries and to develop appropriate preventive interventions.

    The aim of the present meta-analysis was to investigate the associations between three types of peer norms-descriptive norms (peer sexual behaviors), injunctive norms (peer sexual attitudes), and peer pressure to have sex-and two adolescent sexual behavior outcomes (sexual activity and sexual risk behavior). Adolescent sexual activity was more strongly associated with descriptive norms (ESrfixed=.40) than with injunctive norms (ESrfixed=.22) or peer pressure (ESrfixed=.10). Compared with the sexual activity outcome, the effect size for descriptive norms (peer sexual risk behavior) for sexual risk behavior was smaller (ESrfixed=.11). Age, gender, peer type, and socio-cultural context significantly moderated these associations. Additional analyses of longitudinal studies suggested that selection effects were stronger than socialization effects. These findings offer empirical support for the conceptual distinction between three types of peer norms and hold important implications for theory, research, and intervention strategies.

Quaternions are defined, as are equality, addition, scalar multiplication, subtraction, multiplication, conjugation, inverse, and norm of quaternions. The theory is translated into meaningful terms with a discussion of trigonmetric form, sign convention, vector transformation, quaternion combination, quaternion attitude error, attitude rate, attitude update, attitude maneuvers, and orthonormality. The band angle readout system, a spherical inertial measurement unit, is discussed, and the extraction of the quaternion equivalent to the flight program attitude data is analyzed

  4. Comparing three attitude-behavior theories for predicting science teachers' intentions

    Social psychologists' attitude-behavior theories can contribute to understanding science teachers' behaviors. Such understanding can, in turn, be used to improve professional development. This article describes leading attitude-behavior theories and summarizes results from past tests of these theories. A study predicting science teachers' intention to incorporate environmental risk education based on these theories is also reported. Data for that study were collected through a mail questionnaire (n = 1336, radjusted = 80%) and analyzed using confirmatory factor and multiple regression analysis. All determinants of intention to act in the Theory of Reasoned Action and Theory of Planned Behavior and some determinants in the Theory of Trying predicted science teachers' environmental risk education intentions. Given the consistency of results across studies, the Theory of Planned Behavior augmented with past behavior is concluded to provide the best attitude-behavior model for predicting science teachers' intention to act. Thus, science teachers' attitude toward the behavior, perceived behavioral control, and subjective norm need to be enhanced to modify their behavior. Based on the Theory of Trying, improving their attitude toward the process and toward success, and expectations of success may also result in changes. Future research should focus on identifying determinants that can further enhance the ability of these theories to predict and explain science teachers' behaviors.

  11. The Haskell norm

    NASA Astrophysics Data System (ADS)

    Advocate, Dev L.

    The matter of the viscosity of the mantle has started to become serious. In 1935, Norm Haskell estimated the viscosity to be about 1020 poise and there the matter stood for about half a century. For a little while, people worried about excess ellipticity of the Earth and attributed this to a “fossil bulge” that lagged the rotation rate. For this same little while, 1025 poise was thought to be the viscosity of the lower mantle, but then it was discovered that the equator was also out of shape by about the same amount, ruling out the “fossil bulge” idea. To cover their embarrassment, geodynamicists upped the viscosity of the mantle to 1021 by adopting S.I. (Satan's Invention) units. No one noticed for some time since it didn't really matter whether viscosity was given in stokes, poise, or pascal seconds. It was just a large number with a large uncertainty and no one had a feel for it anyway.

  13. Arbitrary norm support vector machines.

    PubMed

    Huang, Kaizhu; Zheng, Danian; King, Irwin; Lyu, Michael R

    2009-02-01

    Support vector machines (SVM) are state-of-the-art classifiers. Typically L2-norm or L1-norm is adopted as a regularization term in SVMs, while other norm-based SVMs, for example, the L0-norm SVM or even the L(infinity)-norm SVM, are rarely seen in the literature. The major reason is that L0-norm describes a discontinuous and nonconvex term, leading to a combinatorially NP-hard optimization problem. In this letter, motivated by Bayesian learning, we propose a novel framework that can implement arbitrary norm-based SVMs in polynomial time. One significant feature of this framework is that only a sequence of sequential minimal optimization problems needs to be solved, thus making it practical in many real applications. The proposed framework is important in the sense that Bayesian priors can be efficiently plugged into most learning methods without knowing the explicit form. Hence, this builds a connection between Bayesian learning and the kernel machines. We derive the theoretical framework, demonstrate how our approach works on the L0-norm SVM as a typical example, and perform a series of experiments to validate its advantages. Experimental results on nine benchmark data sets are very encouraging. The implemented L0-norm is competitive with or even better than the standard L2-norm SVM in terms of accuracy but with a reduced number of support vectors, -9.46% of the number on average. When compared with another sparse model, the relevance vector machine, our proposed algorithm also demonstrates better sparse properties with a training speed over seven times faster. PMID:19431269

    2004-01-01

    A novel approach is presented in this paper to analyze attitude precision and control for an instrument gimbaled to a spacecraft subject to an internal disturbance caused by a moving component inside the instrument. Nonlinear differential equations of motion for some sample cases are derived and solved analytically to gain insight into the influence of the disturbance on the attitude pointing error. A simple control law is developed to eliminate the instrument pointing error caused by the internal disturbance. Several cases are presented to demonstrate and verify the concept presented in this paper.

    Abrams, Dominic; de Moura, Georgina Randsley; Marques, José M; Hutchison, Paul

    2008-09-01

    Two preliminary studies and 5 experiments examined judgments of leaders who challenge their group's norms. Participants viewed information about group members whose attitudes were normative or deviated in a pronormative or antinormative direction. The antinorm member was identified as (a) either a nonleader or an established leader (Study 1), (b) an ex-leader (Studies 2 and 5), or (c) a future leader (Studies 3, 4, and 5). Antinorm future leaders were judged more positively and were granted greater innovation credit (license to innovate and remuneration) relative to antinorm members, ex-leaders, and established leaders. Results are discussed in terms of the idea that leadership can accrue from prototypicality and can also confer the right to define prescriptive norms. However, innovation credit is only granted in the case of future leaders. PMID:18729701

    This paper argues that the goals people have when reasoning determine their own norms of reasoning. A radical descriptivism which avoids norms never worked for any science; nor can it work for the psychology of reasoning. Norms as we understand them are illustrated with examples from categorical syllogistic reasoning and the “new paradigm” of subjective probabilities. We argue that many formal systems are required for psychology: classical logic, non-monotonic logics, probability logics, relevance logic, and others. One of the hardest challenges is working out what goals reasoners have and choosing and tailoring the appropriate logics to model the norms those goals imply. PMID:25368590

    We investigated alcohol-related sexual risk behavior from the perspective of social norms theory. Adults (N = 895, 62% men) residing in a South African township completed street-intercept surveys that assessed risk and protective behaviors (e.g., multiple partners, drinking before sex, meeting sex partners in shebeens, condom use) and corresponding norms. Men consistently overestimated the actual frequency of risky behaviors, as reported by the sample, and underestimated the frequency of condom use. Relative to actual attitudes, men believed that other men were more approving of risk behavior and less approving of condom use. Both behavioral and attitudinal norms predicted the respondents' self-reported risk behavior. These findings indicate that correcting inaccurate norms in HIV-risk reduction efforts is worthwhile.

    2013-06-01

    While reading behaviour of adolescents is a frequent object of research, most studies in this field are restricted to a single country. This study investigates reading as a leisure-time activity across social groups from three regions differing in reading tradition as well as in the facilities available for reading. The authors analyse the reading behaviour of a total of 2,173 adolescents in the Netherlands, in Beijing (China), and in Cape Town (South Africa). Taking Icek Ajzen's Theory of Planned Behaviour as a starting point, the authors adjusted it to model the three most important determinants of reading behaviour, namely (1) reading attitude; (2) subjective norms (implicit and explicit social pressure to read); and (3) perceived behavioural control, which includes reading proficiency and appropriateness of the available books (book supply). While they found the adjusted model to fit the Dutch and Beijing situation quite well, it appeared to be inappropriate for the Cape Town situation. Despite considerable cultural and situational differences between the Netherlands and Beijing, the results show a similar pattern for these two environments. The most important determinants turn out to be: the hedonic reading attitude, the implicit norm of family and friends, the attractiveness of the available choice of books, and the perceived reading proficiency.

    Rohling, Martin L; Miller, Ronald M; Axelrod, Bradley N; Wall, Jacqueline R; Lee, Amy J H; Kinikini, Daniel T

    2015-11-01

    Researchers who have been responsible for developing test batteries have argued that competent practice requires the use of a "fixed battery" that is co-normed. We tested this assumption with three normative systems: co-normed, meta-regressed norms and a system of these two methods. We analyzed two samples: 330 referred patients and 99 undergraduate volunteers. The T scores generated for referred patients using the three systems were highly associated with one another and quite similar in magnitude, with an Overall Test Battery Means (OTBMs) using the co-normed, hybrid, and meta-regressed scores equaled 43.8, 45.0, and 43.9, respectively. For volunteers, the OTBMs equaled 47.4, 47.5, and 47.1, respectively. The correlations amongst these OTBMs across systems were all above .90. Differences among OTBMs across normative systems were small and not clinically meaningful. We conclude that co-norming for competent clinical practice is not necessary. PMID:26152291

    Cooperative behavior depends on cultural environment, so what happens when people move from to a new culture governed by a new norm? The dynamics of culture-induced cooperation has not been well understood. We expose lab participants to a sequence of different subject pools while playing a constrained Trust Game. We find prior exposure to different subject pools does in fact influence cooperative behavior; first impressions matter—the primacy effect plays a stronger role than the recency effect; and selfish first impressions matter more than cooperative first impressions—observing selfish behavior by others had a longer-lasting and greater influence on behaviors than observing cooperative behavior by others. Moreover, three consecutive exposures to cooperative environments were needed to neutralize one exposure to a selfish environment. PMID:26578993

    Gay, lesbian, bisexual, and transgendered individuals are sexual and gender minorities subject to stigma in a heteronormative culture with binary gender role norms. Although much research has examined sexual stigma in the form of homophobia, or negative attitudes and reactions to homosexuals and homosexuality, little is known about the stigma experienced by transgendered individuals. Transgendered people are those whose gender identity (sense of oneself as a man or a woman) or gender expression (expression of oneself as a man or a woman in behavior, manner, and/or dress) differ from conventional expectations for their physical sex. Although a scale exists to measure transphobia or negative attitudes and reactions to transgendered individuals, it includes items tapping into overt behavioral expression of this stigma, or gender-bashing, and fails to identify or define transgendered persons as the attitudinal target of the items. A new scale was developed and evaluated in an effort to assess transgender-related stigma, separately from discrimination and violence, among members of the general population. Using two separate samples of college students ranging in age from 18-64 years, exploratory (N = 134) and confirmatory factor analyses (N = 237) were performed. The resulting 20-item, self-report measure demonstrated a single-factor structure, high internal consistency reliability, and evidence of convergent and discriminant construct validity.

    Paluck, Elizabeth Levy

    2009-03-01

    This reply to the commentary by E. Staub and L. A. Pearlman (2009) revisits the field experimental results of E. L. Paluck (2009). It introduces further evidence and theoretical elaboration supporting Paluck's conclusion that exposure to a reconciliation-themed radio soap opera changed perceptions of social norms and behaviors, not beliefs. Experimental and longitudinal survey evidence reinforces the finding that the radio program affected socially shared perceptions of typical or prescribed behavior-that is, social norms. Specifically, measurements of perceptions of social norms called into question by Staub and Pearlman are shown to correlate with perceptions of public opinion and public, not private, behaviors. Although measurement issues and the mechanisms of the radio program's influence merit further testing, theory and evidence point to social interactions and emotional engagement, not individual education, as the likely mechanisms of change. The present exchange makes salient what is at stake in this debate: a model of change based on learning and personal beliefs versus a model based on group influence and social norms. These theoretical models recommend very different strategies for prejudice and conflict reduction. Future field experiments should attempt to adjudicate between these models by testing relevant policies in real-world settings. PMID:19254106

  19. Quality of decision making and group norms.

    PubMed

    Postmes, T; Spears, R; Cihangir, S

    2001-06-01

    Two studies investigated the impact of group norms for maintaining consensus versus norms for critical thought on group decisions in a modification of the biased sampling paradigm (G. Stasser & W. Titus, 1985). Both studies showed that critical norms improved the quality of decisions, whereas consensus norms did not. This effect appeared to be mediated by the perceived value of shared and unshared information: Consensus norm groups valued shared information more highly than critical groups did, and valence was a good predictor of decision outcome. In addition, the 2nd study showed that the group norm manipulation has no impact on individual decisions, consistent with the assumption that this is a group effect. Results suggest that the content of group norms is an important factor influencing the quality of group decision-making processes and that the content of group norms may be related to the group's proneness for groupthink.

    Taxpayers' willingness to cooperate with the state and its institutions in general, and their willingness to pay taxes in particular, depend on a variety of variables. While economists stress the relevance of external variables such as tax rate, income and probability of audits and severity of fines, psychological research shows that internal variables are of similar importance. We present a comprehensive review on the relevance of citizens' knowledge of tax law, their attitudes towards the government and taxation, personal norms, perceived social norms and fairness, as well as motivational tendencies to comply, and discuss possibilities for strategic intervention to increase tax compliance.

  1. Attitude Estimation or Quaternion Estimation?

    NASA Technical Reports Server (NTRS)

    Markley, F. Landis

    2003-01-01

    The attitude of spacecraft is represented by a 3x3 orthogonal matrix with unity determinant, which belongs to the three-dimensional special orthogonal group SO(3). The fact that all three-parameter representations of SO(3) are singular or discontinuous for certain attitudes has led to the use of higher-dimensional nonsingular parameterizations, especially the four-component quaternion. In attitude estimation, we are faced with the alternatives of using an attitude representation that is either singular or redundant. Estimation procedures fall into three broad classes. The first estimates a three-dimensional representation of attitude deviations from a reference attitude parameterized by a higher-dimensional nonsingular parameterization. The deviations from the reference are assumed to be small enough to avoid any singularity or discontinuity of the three-dimensional parameterization. The second class, which estimates a higher-dimensional representation subject to enough constraints to leave only three degrees of freedom, is difficult to formulate and apply consistently. The third class estimates a representation of SO(3) with more than three dimensions, treating the parameters as independent. We refer to the most common member of this class as quaternion estimation, to contrast it with attitude estimation. We analyze the first and third of these approaches in the context of an extended Kalman filter with simplified kinematics and measurement models.

    PubMed

    2007-03-01

    Two routes to overeating are discussed; they are both premised on people's strong motivation to avoid eating excessively and thereby avoid negative ascriptions associated with the overeatingloverweight stereotype. The first route to overeating involves infractions of restrictive intake norms: people who attempt to restrict their intake by implementing dietary rules often run afoul of disinhibitory circumstances that undermine the self-control upon which successful dieting depends. The second route to overeating involves adherence to restrictive intake norms in situations where it is unclear how much eating is permitted. People search the environment for indicants of what constitutes permissible intake and end up relying on such arbitrary criteria as portion size and the intake of other people. Using such criteria derived from the eating situation often leads to overeating even while individuals believe that they are successfully restricting their intake. PMID:17598384

    2009-01-01

    Attitudes, perceived social norms and intentions were assessed for 376 counselors and 1083 clients from outpatient, methadone and residential drug treatment programs regarding four medications used to treat opiate dependence: methadone, buprenorphine, clonidine, and ibogaine. Attitudes, social norms and intentions to use varied by treatment modality. Methadone clients and counselors had more positive attitudes toward the use of methadone, while their counterparts in residential and outpatient settings had neutral or negative assessments. Across modalities, attitudes, perceived social norms, and intentions toward the use of buprenorphine were relatively neutral. Assessments of clonidine and ibogaine were negative for clients and counselors in all settings. Social normative influences were dominant across settings and medications in determining counselor and client intentions to use medications, suggesting that perceptions about beliefs of peers may play a critical role in use of medications to treat opiate dependence.

    Positive attitude towards learning is vital in order to master the core content of the subject matters under study. This is unexceptional in learning statistics course especially at the university level. Therefore, this study investigates the students' attitude towards learning statistics. Six variables or constructs have been identified such as affect, cognitive competence, value, difficulty, interest, and effort. The instrument used for the study is questionnaire that was adopted and adapted from the reliable instrument of Survey of Attitudes towards Statistics(SATS©). This study is conducted to engineering undergraduate students in one of the university in the East Coast of Malaysia. The respondents consist of students who were taking the applied statistics course from different faculties. The results are analysed in terms of descriptive analysis and it contributes to the descriptive understanding of students' attitude towards the teaching and learning process of statistics.

    2013-03-01

    This study proposed the Reference Group Perspective for smoking cessation, examining smokers' identification with three reference groups: best friends, colleagues, and family members, and hypothesizing that identification with each group would moderate the relationship between injunctive and descriptive norms of the group and smoking cessation self-efficacy. Results of an online questionnaire (N = 208) indicated that injunctive and descriptive norms of all three reference groups significantly affected smoking cessation self-efficacy, and this relationship was moderated by identification. Injunctive norms were stronger in predicting smoking cessation self-efficacy than descriptive norms, with injunctive norms of family members and descriptive norms of best friends having the most significant effect. Positive attitude toward smoking was also significantly associated with smoking cessation self-efficacy. PMID:22732053

    2013-01-01

    This study examined parents’ normative perceptions of other college parents’ alcohol-specific communication, and how parents’ perceived communication norms and alcohol-specific communication relate to student drinking outcomes. A sample of 457 student-parent dyads were recruited from a mid-size university. Students completed web-based assessments of alcohol-related attitudes and behaviors. Parents completed alcohol-specific measures of communication norms and parent-child communication, including communication content (i.e., targeted communication) and frequency of communication. Results indicated that parents overestimated how much other parents talked to their college students about the frequency and quantity of alcohol use, but underestimated how often parents initiated conversations about alcohol. In a path model, perceived communication norms positively predicted both targeted communication and frequency of communication. Perceived communication norms and targeted communication negatively predicted students’ attitude toward alcohol use. In contrast, more frequent communication predicted students holding more approving attitudes toward alcohol. The relationship between parents’ perceived communication norms and students’ drinking behaviors was mediated by the parental communication variables and student attitudes. Tests of indirect effects were undertaken to examine meditational processes. The findings underscore relations involving parental perceived communication norms and parents’ own alcohol communication and their children’s drinking outcomes. The complex relationships of different types of parental communication and student outcomes warrant further research. PMID:24128293

    2011-01-01

    This paper responds to the call for culturally relevant intervention research by introducing a methodology for identifying community norms and resources in order to more effectively implement sustainable interventions strategies. Results of an analysis of community norms, specifically attitudes toward gender equity, are presented from an HIV/STI research and intervention project in a low income community in Mumbai, India (2008–2012). Community gender norms were explored because of their relevance to sexual risk in settings characterized by high levels of gender inequity. This paper recommends approaches that interventionists and social scientists can take to incorporate cultural insights into formative assessments and project implementation These approaches include how to (1) examine modal beliefs and norms and any patterned variation within the community; (2) identify and assess variation in cultural beliefs and norms among community members (including leaders, social workers, members of civil society and the religious sector); and (3) identify differential needs among sectors of the community and key types of individuals best suited to help formulate and disseminate culturally relevant intervention messages. Using a multi-method approach that includes the progressive translation of qualitative interviews into a quantitative survey of cultural norms, along with an analysis of community consensus, we outline a means for measuring variation in cultural expectations and beliefs about gender relations in an urban community in Mumbai. Results illustrate how intervention strategies and implementation can benefit from an organic (versus a priori and/or stereotypical) approach to cultural characteristics and analysis of community resources and vulnerabilities.

    Social norms around condom use and safe sex as well as HIV/AIDS stigma are used to identify persons at higher risk for HIV. These measures have been developed and tested in a variety of settings and populations. While efforts have been undertaken to develop context specific measures of these domains among Chinese MSM, the feasibility of using existing measures is unknown. A survey of MSM, based on respondent-driven sampling, was conducted in Beijing. Existing measures of condom social norms, attitudes towards safer sex and HIV/AIDS stigma were piloted. Internal consistency of all measures was high. As expected higher levels of condom social norms and positive attitudes towards safer sex were associated with condom use. HIV/AIDS stigma and discrimination had a significant relationship with never having an HIV test and lack of discussion of HIV/AIDS with male partners. Correlates of low condom social norms were age, education, employment and resident status. Existing measures of condom social norms, attitudes towards safer sex and HIV/AIDS stigma appear to be appropriate for use among Chinese MSM. Using existing measures as opposed to developing new measures has the potential to expedite investigations into psychosocial correlates of HIV risk behavior. PMID:24057931

    2014-09-01

    Perceived descriptive norms are one of the strongest predictors of college drinking. Social Identity Theory posits that much of our identity is based on groups with which we affiliate. Prior research suggests that there is an association between perceived descriptive norms and drinking among those who identify more strongly with the normative referent group. However, no studies to date have examined how different facets of social identity affect the relationship between perceived descriptive norms and drinking. The purpose of this study was to examine whether the interaction between perceived descriptive norms and social identity on drinking varied as a function of different dimensions of social identity among college students. Participants were 1095 college students from a large, public, southern university who completed an online survey about drinking behaviors and related attitudes. Drinks per week was examined as a function of norms, the Importance, Commitment, Deference, and Superiority subscales of the Measure of Identification with Groups, as well as the two-way interactions between each dimension of social identity and norms. Results indicated that norms were associated with drinking, but that this relationship varied as a function of identity dimension. The association between norms and drinking was stronger among those who viewed the university's student body as part of their own identity and were more committed to their fellow students, but weaker among those who reported greater deference to student leaders. This research suggests the importance of examining multiple dimensions of social identity in considering social influences on drinking. PMID:24836160

    Norm stability is an important issue to consider in using the normative approach as a component of resource management decision making. This study examines three major questions related to norm stability: (1) Do norms change over time? (2) Do existing conditions affect norms? (3) Do background characteristics and visitation patterns affect norms? Data used in this study were collected at a campground in the Jirisan National Park (JNP) of Korea in 1993, 1994, and 2003. A total of 396 subjects were used for the study (120 for 1993, 106 for 1994, and 170 for 2003). Changes in the standards for "quiet time" and "seeing others littering" were statistically significant, but there was no change in the standard for "number of other tents." There was little change in norm agreement or norm prevalence. Existing conditions were strongly correlated with standards for number of other tents but results were mixed for the other two indicators. Users' demographic characteristics and visitation patterns were not generally related to norms. Findings of the study are discussed. PMID:18214588

    We consider an infinite planar straight strip perforated by small holes along a curve. In such domain, we consider a general second order elliptic operator subject to classical boundary conditions on the holes. Assuming that the perforation is non-periodic and satisfies rather weak assumptions, we describe all possible homogenized problems. Our main result is the norm resolvent convergence of the perturbed operator to a homogenized one in various operator norms and the estimates for the rate of convergence. On the basis of the norm resolvent convergence, we prove the convergence of the spectrum.

  10. Understanding Community Norms Surrounding Tobacco Sales

    McDaniel, Patricia A.; Malone, Ruth E.

    2014-01-01

    Background In the US, denormalizing tobacco use is key to tobacco control; less attention has been paid to denormalizing tobacco sales. However, some localities have placed limits on the number and type of retailers who may sell tobacco, and some retailers have abandoned tobacco sales voluntarily. Understanding community norms surrounding tobacco sales may help accelerate tobacco denormalization. Methods We conducted 15 focus groups with customers of California, New York, and Ohio retailers who had voluntarily discontinued tobacco sales to examine normative assumptions about where cigarettes should or should not be sold, voluntary decisions to discontinue tobacco sales, and government limits on such sales. Results Groups in all three states generally agreed that grocery stores that sold healthy products should not sell tobacco; California groups saw pharmacies similarly, while this was a minority opinion in the other two states. Convenience stores were regarded as a natural place to sell tobacco. In each state, it was regarded as normal and commendable for some stores to want to stop selling tobacco, although few participants could imagine convenience stores doing so. Views on government's role in setting limits on tobacco sales varied, with California and New York participants generally expressing support for restrictions, and Ohio participants expressing opposition. However, even those who expressed opposition did not approve of tobacco sales in all possible venues. Banning tobacco sales entirely was not yet normative. Conclusion Limiting the ubiquitous availability of tobacco sales is key to ending the tobacco epidemic. Some limits on tobacco sales appear to be normative from the perspective of community members; it may be possible to shift norms further by problematizing the ubiquitous presence of cigarettes and drawing connections to other products already subject to restrictions.

    2002-02-01

    Sentence completion norms are a valuable resource for researchers interested in studying the effects of context on word recognition processes. Norms for 112 Spanish sentences were compiled with the use of experimental software accessed over the World-Wide Web. Several measures summarizing the distribution of responses for each sentence are reported, including Schwanenflugel's (1986) multiple-production measure of sentence constraint strength, the type-token ratio, and the information-theoretic measure of redundancy. The complete set of completion norms is available at http://www.ling.ed.ac.uk/~monica/spanish_completion_norms.html. PMID:12060986

  14. Measuring attitude with a gradiometer

    Sonnabend, David; Gardner, Thomas G.

    1994-01-01

    This paper explores using a gravity gradiometer to measure the attitude of a satellite, given that the gravity field is accurately known. Since gradiometers actually measure a combination of the gradient and attitude rate and acceleration terms, the answer is far from obvious. The paper demonstrates that it can be done and at microradian accuracy. The technique employed is dynamic estimation, based on the momentum biased Euler equations. The satellite is assumed nominally planet pointed, and subject to control, gravity gradient, and partly radom drag torques. The attitude estimator is unusual. While the standard method of feeding back measurement residuals is used, the feedback gain matrix isn't derived from Kalman theory. instead, it's chosen to minimize a measure of the terminal covariance of the error in the estimate. This depends on the gain matrix and the power spectra of all the process and measurement noises. An integration is required over multiple solutions of Lyapunov equations.

  19. Sex-specific norms code face identity.

    PubMed

    Rhodes, Gillian; Jaquet, Emma; Jeffery, Linda; Evangelista, Emma; Keane, Jill; Calder, Andrew J

    2011-01-01

    Face identity aftereffects suggest that an average face, which is continuously updated by experience, functions as a norm for coding identity. Sex-contingent figural face aftereffects indicate that different norms are maintained for male and female faces but do not directly implicate them in coding identity. Here, we investigated whether sex-specific norms are used to code the identities of male and female faces or whether a generic, androgynous norm is used for all faces. We measured identity aftereffects for adapt-test pairs that were opposite relative to a sex-specific average and pairs that were opposite relative to an androgynous average. Identity aftereffects are generally larger for adapt-test pairs that lie opposite an average face, which functions as a norm for coding identity, than those that do not. Therefore, we reasoned that whichever average gives the larger aftereffect would be closer to the true psychological norm. Aftereffects were substantially and significantly larger for pairs that lie opposite a sex-specific than an androgynous average. This difference remained significant after correcting for differences in test trajectory length. These results indicate that, despite the common structure shared by all faces, identity is coded using sex-specific norms. We suggest that the use of category-specific norms may increase coding efficiency and help us discriminate thousands of faces despite their similarity as patterns. PMID:21199895

    2015-11-04

    In low-rank matrix recovery, one aims to reconstruct a low-rank matrix from a minimal number of linear measurements. Within the paradigm of compressed sensing, this is made computationally efficient by minimizing the nuclear norm as a convex surrogate for rank. In this work, we identify an improved regularizer based on the so-called diamond norm, a concept imported from quantum information theory. We show that - for a class of matrices saturating a certain norm inequality - the descent cone of the diamond norm is contained in that of the nuclear norm. This suggests superior reconstruction properties for these matrices and we explicitly characterize this set. We demonstrate numerically that the diamond norm indeed outperforms the nuclear norm in a number of relevant applications: These include signal analysis tasks such as blind matrix deconvolution or the retrieval of certain unitary basis changes, as well as the quantum information problem of process tomography with random measurements. The diamond norm is defined for matrices that can be interpreted as order-4 tensors and it turns out that the above condition depends crucially on that tensorial structure. In this sense, this work touches on an aspect of the notoriously difficult tensor completion problem.

    Alexey E. Rastegin

    2012-08-30

    Changes of some unitarily invariant norms and anti-norms under the operation of partial trace are examined. The norms considered form a two-parametric family, including both the Ky Fan and Schatten norms as particular cases. The obtained results concern operators acting on the tensor product of two finite-dimensional Hilbert spaces. For any such operator, we obtain upper bounds on norms of its partial trace in terms of the corresponding dimensionality and norms of this operator. Similar inequalities, but in the opposite direction, are obtained for certain anti-norms of positive matrices. Through the Stinespring representation, the results are put in the context of trace-preserving completely positive maps. We also derive inequalities between the unified entropies of a composite quantum system and one of its subsystems, where traced-out dimensionality is involved as well.

  3. How intergenerational interaction affects attitude-behavior inconsistency.

    Sekiguchi, Takuya; Nakamaru, Mayuko

    2014-04-01

    Social norms play an important role in maintaining social order, but at the same time, they can act as a constraint that compels people to take specific actions which run contrary to their attitudes. This paper treats the latter case: we investigate conditions in which attitude-behavior inconsistency persists, constructing mathematical models combining evolutionary games and cultural transmissions. In particular, we focus on the effect of intergenerational interactions. Our models show that both information about others' attitude (e.g., through social surveys) and the combination of intra- and inter-generational interactions are key factors to generate the situation where all people adopt the same behavior but different people have different attitudes.

    1989-01-01

    By means of a simple structural problem, an important requirement often overlooked in practice on the basis functions used in Rayleigh-Ritz-Galerkin type methods is brought into focus. The problem of the static deformation of a uniformly loaded beam is solved variationally by expanding the beam displacement in a Fourier Cosine series. The potential energy functional is rendered stationary subject to the geometric boundary conditions. It is demonstrated that the variational approach does not converge to the true solution. The object is to resolve this paradox, and in so doing, indicate the practical implications of norms and completeness in an appropriate inner product space.

    Imbir, Kamil K

    2015-09-01

    This article presents valence/pleasantness, activity/arousal, power/dominance, origin, subjective significance, and source-of-experience norms for 1,586 Polish words (primarily nouns), adapted from the Affective Norms for English Words list (1,040 words) and from my own previous research (546 words), regarding the duality-of-mind approach for emotion formation. This is a first attempt at creating affective norms for Polish words. The norms are based on ratings by a total of 1,670 college students (852 females and 818 males) from different Warsaw universities and academies, studying various disciplines in equal proportions (humanities, engineering, and social and natural sciences) using a 9-point Likert Self-Assessment Manikin scale. Each participant assessed 240 words on six different scales (40 words per scale) using a paper-and-pencil group survey procedure. These affective norms for Polish words are a valid and useful tool that will allow researchers to use standard, well-known verbal materials comparable to the materials used in other languages (English, German, Portuguese, Spanish, French, Dutch, etc.). The normative values of the Polish adaptation of affective norms are included in the online supplemental materials for this article. PMID:25294041

    Objective: The goal of this study was to explore the effect of subjective peer norms on adolescents’ willingness to drink and whether this association was moderated by sensitivity to peer approval, prior alcohol use, and gender. Method: The sample was 1,023 middle-school students (52% female; 76% White; 12% Hispanic; Mage = 12.22 years) enrolled in a prospective study of drinking initiation and progression. Using web-based surveys, participants reported on their willingness to drink alcohol if offered by (a) a best friend or (b) a classmate, peer norms for two referent groups (close friends and classmates), history of sipping or consuming a full drink of alcohol, and sensitivity to peer approval (extreme peer orientation). Items were re-assessed at two follow-ups (administered 6 months apart). Results: Multilevel models revealed that measures of peer norms were significantly associated with both willingness outcomes, with the greatest prediction by descriptive norms. The association between norms and willingness was magnified for girls, those with limited prior experience with alcohol, and youths with low sensitivity to peer approval. Conclusions: Social norms appear to play a key role in substance use decisions and are relevant when considering more reactive behaviors that reflect willingness to drink under conducive circumstances. Prevention programs might target individuals with higher willingness, particularly girls who perceive others to be drinking and youths who have not yet sipped alcohol but report a higher perceived prevalence of alcohol consumption among both friends and peers.

    2015-01-01

    Recent theories suggest an important role of neuroticism, extraversion, attitudes, and global positive orientations as predictors of subjective happiness. We examined whether positivity mediates the hypothesized relations in a community sample of 504 adults between the ages of 20 and 60 years old (females = 50%). A model with significant paths from neuroticism to subjective happiness, from extraversion and neuroticism to positivity, and from positivity to subjective happiness fitted the data (Satorra–Bentler scaled chi-square (38) = 105.91; Comparative Fit Index = .96; Non-Normed Fit Index = .95; Root Mean Square Error of Approximation = .060; 90% confidence interval = .046, .073). The percentage of subjective happiness variance accounted for by personality traits was only about 48%, whereas adding positivity as a mediating factor increased the explained amount of subjective happiness to 78%. The mediation model was invariant by age and gender. The results show that the effect of extraversion on happiness was fully mediated by positivity, whereas the effect of neuroticism was only partially mediated. Implications for happiness studies are also discussed. PMID:25781887

    Aims: The Aim of the study was to establish Soft Tissue Cephalometric Norms for skeletal and dental relationships amongst the Mahabubnagar adult population. Materials and Methods: Sixty subjects (30 Males & 30 Females) subjects from different part of Mahabubnagar in the age group 18-25 Years (Mean age 21.3 Years) were selected at random for the study and lateral cephalograms were taken. All the cephalograms were traced by two operators using conventional hand tracing. The parameters used in the study were taken from Arnett and Bergman soft tissue cephalometric analysis (STCA). Overall 46 measurements including 40 linear, 6 angular parameters were used. Mean and standard deviation values were calculated. The difference between males and females were evaluated using student t-test. Results: The values obtained from the study showed significant difference in most of the parameters from that of Arnett et al., norms and between males and females within Mahabubnagar population. Conclusion: Males had thicker soft tissue structures, acute nasolabial angle, increased facial lengths and heights, increased midface deficiency, recessive lower face, more convex profile and less upright mandibular incisors than females within Mahabubnagar population.

    We present a study comparing, in English, perceived distributions of men and women in 422 named occupations with actual real world distributions. The first set of data was obtained from previous a large-scale norming study, whereas the second set was mostly drawn from UK governmental sources. In total, real world ratios for 290 occupations were obtained for our perceive vs. real world comparison, of which 205 were deemed to be unproblematic. The means for the two sources were similar and the correlation between them was high, suggesting that people are generally accurate at judging real gender ratios, though there were some notable exceptions. Beside this correlation, some interesting patterns emerged from the two sources, suggesting some response strategies when people complete norming studies. We discuss these patterns in terms of the way real world data might complement norming studies in determining gender stereotypicality. PMID:26257681

    The purpose of image steganalysis is to detect the presence of hidden messages in cover images. Steganalysis can be considered as a pattern recognition process to decide which class a test image belongs to: the innocent photographic image or the stego-image. This paper presents a definition of mixed L_{p,q} matrix norm as an extension of L_{2,1} matrix norm. We incorporate discriminative mixed L_{p,q} matrix norm analysis to select the features which best preserve the data distribution, e.g., manifold structure, of the whole feature sets. Experiments on different data sets verify the effectiveness of the proposed approach and the selected features are more discriminate.

The means for the two sources were similar and the correlation between them was high, suggesting that people are generally accurate at judging real gender ratios, though there were some notable exceptions. Beside this correlation, some interesting patterns emerged from the two sources, suggesting some response strategies when people complete norming studies. We discuss these patterns in terms of the way real world data might complement norming studies in determining gender stereotypicality. PMID:26257681

  18. Norms as Group-Level Constructs: Investigating School-Level Teen Pregnancy Norms and Behaviors

    Social norms are a group-level phenomenon, but past quantitative research has rarely measured them in the aggregate or considered their group-level properties. We used the school-based design of the National Longitudinal Study of Adolescent Health to measure normative climates regarding teen pregnancy across 75 U.S. high schools. We distinguished between the strength of a school's norm against teen pregnancy and the consensus around that norm. School-level norm strength and dissensus were strongly (r = -0.65) and moderately (r = 0.34) associated with pregnancy prevalence within schools, respectively. Normative climate partially accounted for observed racial differences in school pregnancy prevalence, but norms were a stronger predictor than racial composition. As hypothesized, schools with both a stronger average norm against teen pregnancy and greater consensus around the norm had the lowest pregnancy prevalence. Results highlight the importance of group-level normative processes and of considering the local school environment when designing policies to reduce teen pregnancy. PMID:26074628

  19. On the complexity of approximating the diamond norm

    2009-09-08

    The diamond norm is a norm defined over the space of quantum transformations. This norm has a natural operational interpretation: it measures how well one can distinguish between two transformations by applying them to a state of arbitrarily large dimension. This interpretation makes this norm useful in the study of quantum interactive proof systems. In this note we exhibit an efficient algorithm for computing this norm using convex programming. Independently of us, Watrous recently showed a different algorithm to compute this norm. An immediate corollary of this algorithm is a slight simplification of the argument of Kitaev and Watrous [STOC 2000] that QIP is contained in EXP.

    Moist-air norms and inner-products are currently used in atmospheric science for computing dry or moist singular vectors and for determining forecast errors or sensitivity to observations based on tangent linear and adjoint models. A new moist-air norm is defined starting from old results published in Marquet (QJRMS 1993) and based on the "Available Enthalpy" approach, namely one of the Exergy function defined in general thermodynamics. Some interesting and promising impacts of this new "Available Enthalpy" norm are described in this brief version of a paper to be submitted to the QJRMS.

    The aim of this study was to evaluate attitudes towards and achievement in science of Form 3 students studying in single-sex and coeducational schools in Brunei. The results demonstrated significant differences in attitudes towards and achievement in science of male and female students in single-sex schools and students in coeducational schools. These differences were at moderate level. In single-sex schools, the girls achieved moderately better in science than the boys despite their attitudes were only marginally better than the boys. However, there were no gender differences in attitudes towards and achievement in science of students in coeducational schools. The attitudes towards and achievement in science of girls in single-sex schools were moderately better than those of girls in coeducational schools. Whereas the attitudes towards and achievement in science of boys in single-sex schools were only marginally better than the boys in coeducational schools. However, further research to investigate (a) if these differences are repeated at other levels as well as in other subjects, and (b) the extent to which school type contributed towards these differences is recommended.

  5. The role of attitude functions, efficacy, anticipated emotions, and relationship status on college students' condom use intentions.

    PubMed

    Wang, Xiao

    2013-01-01

    Conducted from the reasoned action perspective, previous research related to condom use generally included a limited number of variables and treated attitudes and self-efficacy as unidimensional constructs. Informed by attitude functions theory and health literature on condom use and anticipated emotions, this project aims to provide a more detailed understanding of college students' intentions to use condoms during sexual intercourse. Results show that relationship status moderated the relationships between several psychological variables and condom use intentions. For female college students negative anticipated emotions were a stronger predictor of condom use intentions for those in monogamous relationships for three months or longer than for those in other relationships or not in a relationship. On the other hand, subjective norms were a stronger predictor of intentions for those in other types of relationship or not in a relationship than for those in a monogamous relationship for three months or longer. For male participants, sexual sensation was a more important, negative predictor of condom use intentions among those in monogamous relationships for three months or longer (versus other relationship status or not in a relationship). Both theoretical and practical implications are discussed. PMID:22946831

    2007-06-18

    An important problem in quantum information theory is the mathematical characterization of the phenomenon of quantum catalysis: when can the surrounding entanglement be used to perform transformations of a jointly held quantum state under LOCC (local operations and classical communication) ? Mathematically, the question amounts to describe, for a fixed vector $y$, the set $T(y)$ of vectors $x$ such that we have $x \\otimes z \\prec y \\otimes z$ for some $z$, where $\\prec$ denotes the standard majorization relation. Our main result is that the closure of $T(y)$ in the $\\ell_1$ norm can be fully described by inequalities on the $\\ell_p$ norms: $\\|x\\|_p \\leq \\|y\\|_p$ for all $p \\geq 1$. This is a first step towards a complete description of $T(y)$ itself. It can also be seen as a $\\ell_p$-norm analogue of Ky Fan dominance theorem about unitarily invariant norms. The proofs exploits links with another quantum phenomenon: the possibiliy of multiple-copy transformations ($x^{\\otimes n} \\prec y^{\\otimes n}$ for given $n$). The main new tool is a variant of Cram\\'er$ theorem on large deviations for sums of i.i.d. random variables.

  12. Group bias in cooperative norm enforcement.

    PubMed

    McAuliffe, Katherine; Dunham, Yarrow

    2016-01-19

    A hallmark of human social cognition is the tendency for both adults and children to favour members of their own groups. Critically, this in-group bias exerts a strong influence on cooperative decision-making: people (i) tend to share more with members of their in-group and (ii) differentially enforce fairness norms depending on the group membership of their interaction partners. But why do people show these group biases in cooperation? One possibility is that the enforcement of cooperative norm violations is an evolved mechanism supporting within-group cooperation (Norms-Focused Hypothesis). Alternatively, group bias in cooperation could be a by-product of more general affective preferences for in-group members (Mere Preferences Hypothesis). Here, we appraise evidence from studies of both adults and children with the goal of understanding whether one of these two accounts is better supported by existing data. While the pattern of evidence is complex, much of it is broadly consistent with the Mere Preferences Hypothesis and little is uniquely supportive of the Norms-Focused Hypothesis. We highlight possible reasons for this complexity and suggest ways that future work can continue to help us understand the important relationship between group bias and cooperation. PMID:26644592

    Objective: The NIH Toolbox for Assessment of Neurological and Behavioral Function (NIH Toolbox) is a comprehensive battery of brief assessment tools. The purpose of this article is to describe plans to establish normative reference values for the NIH Toolbox measures. Methods: A large sample will be obtained from the US population for the purpose of calculating normative values. The sample will be stratified by age (ages 3–85 years), sex, and language preference (English or Spanish) and have a total sample size of at least 4,205. The sample will include a minimum of 25–100 individuals in each targeted demographic and language subgroup. Results: Norming methods will include poststratification adjustment calculated using iterative proportional fitting, also known as raking, so that the weighted sample will have the same distribution on key demographic variables as the US population described in the 2010 Census. Conclusions: As with any set of norms, users should be mindful of the reference population and make conclusions consistent with the limitations of normative sampling, since it is not a probability-based sample. However, the NIH Toolbox norming study has been designed to minimize bias and maximize representativeness and precision of estimates. The availability of a "toolbox" of normed measures will be an important foundation for addressing critical research questions in neurologic and behavioral health. PMID:23479550

    One of the pressing challenges we face today-in a post-Westphalian order (emergence of the state as the modern, political information agent) and post-Bretton Woods world (emergence of non-state multiagent systems or MASs as "hyperhistorical" players in the global economy and politics)-is how to design the right kind of MAS that can take full advantage of the socio-economic and political progress made so far, while dealing successfully with the new global challenges that are undermining the best legacy of that very progress. This is the topic of the article. In it, I argue that (i) in order to design the right kind of MAS, we need to design the right kind of norms that constitute them; (ii) in order to design the right kind of constitutive norms, we need to identify and adopt the right kind of principles of normative design; (iii) toleration is one of those principles; (iv) unfortunately, its role as a foundation for the design of norms has been undermined by the "paradox of toleration"; (v) however, the paradox can be solved; (vi) so toleration can be re-instated as the right kind of foundational principle for the design of the right kind of norms that can constitute the right kind of MAS that can operate across cultures, societies and states, to help us to tackle the new global challenges facing us.

    2009-06-01

    Up till now, no study satisfactorily addressed the effect of social mobility on antagonistic attitudes toward ethnic minorities. In this contribution, we investigate the effect of educational and class intergenerational mobility on ethnic stereotypes, ethnic threat, and opposition to ethnic intermarriage by using diagonal mobility models. We test several hypotheses derived from ethnic competition theory and socialization theory with data from the Social and Cultural Developments in The Netherlands surveys (SOCON, waves 1995, 2000, and 2005) and The Netherlands Kinship and Panel Study (NKPS, wave 2002). We find that the relative influence of social origin and social destination depends on the specific origin and destination combination. If one moves to a more tolerant social destination position, the influence of the social origin position is negligible. If on the other hand, one is socially mobile to a less tolerant social position, the impact of the origin on antagonistic attitudes is substantial and may even exceed the impact of the destination category. This confirms our hypothesis that adaptation to more tolerant norms is easier than adaptation to less tolerant norms. We find only meagre evidence for the hypothesis that downward mobility leads to frustration and consequently to more antagonistic attitudes. PMID:19489819

    We explore three analytic methods that can be used to quantify and qualify changes in attitude and similar outcomes that may be encountered in the educational context. These methods can be used or adapted whenever the outcome of interest is change in a generally unmeasurable attribute, such as attitude. The analyses we describe focus on: (1) change in total ‘attitude score’; (2) item-level changes in attitudes towards different topics; and (3) ‘attitude shift’ that is defined based on a qualified change algorithm. In our example data, the total-score approach gives a general index to the level of positive attitude; the item-level approach gives the median level of positive attitude and indicates items with the most positive/negative attitude (i.e., items to target in future iterations). The qualified change approach provides an objective measure of whether a shift in attitude has occurred. Each analysis is described with its advantages and disadvantages using the data from a survey of 70 preclinical first and second year medical students before and after an elective 11-week interactive seminar (22 contact hours) which introduced elements of complementary and alternative medicine (CAM) into programmed medical school training. When assessing changes that are more qualitative than quantitative, any of these methods can be employed to derive either descriptive or inferential statistics. The methods are straightforward and are appropriate when measurements are imperfect, ratings are subjective and differences are not necessarily absolute

  8. Singular Vectors for Moisture-Measuring Norms

    2002-01-01

    In dynamic meteorology, singular vectors (SVs) are the structures that maximize a given norm of a forecast perturbation given a tangent linear model and a quadratic constraint on the initial perturbation. That constraint is a prescription of the value of either the same or a different norm applied to the initial perturbations. In the sense that SVs maximize the forecast perturbations according to a specified measure, they may be considered as optimal perturbations. SVs are used to characterize predictability, to identify and correct possible initial errors given forecast errors, to create a set of significant perturbations for ensemble forecasting, or to determine locations for observation targeting. They are a specific application of generally defined singular vectors in mathematics.

  9. Norm-based measurement of quantum correlation

    In this paper we derived a necessary and sufficient condition for classical correlated states and proposed a norm-based measurement Q of quantum correlation. Using the max norm of operators, we gave the expression of the quantum correlation measurement Q and investigated the dynamics of Q in Markovian and non-Markovian cases, respectively. Q decays exponentially and vanishes only asymptotically in the Markovian case and causes periodical death and rebirth in the non-Markovian case. In the pure state, the quantum correlation Q is always larger than the entanglement, which was different from other known measurements. In addition, we showed that locally broadcastable and broadcastable are equivalent and reproved the density of quantum correlated states.

  14. Dictator Game Giving: The Importance of Descriptive versus Injunctive Norms

    Raihani, Nichola J.; McAuliffe, Katherine

    2014-01-01

    Human behaviour is influenced by social norms but norms can entail two types of information. Descriptive norms refer to what others do in this context, while injunctive norms refer to what ought to be done to ensure social approval. In many real-world situations these norms are often presented concurrently meaning that their independent effects on behaviour are difficult to establish. Here we used an online Dictator Game to test how descriptive and injunctive norms would influence dictator donations when presented independently of one another. In addition, we varied the cost of complying with the norm: By stating that $0.20 or $0.50 cent donations from a $1 stake were normal or suggested, respectively. Specifying a higher target amount was associated with increased mean donation size. In contrast to previous studies, descriptive norms did not seem to influence giving behaviour in this context, whereas injunctive norms were associated with increased likelihood to give at least the target amount to the partner. This raises the question of whether injunctive norms might be more effective than descriptive norms at promoting prosocial behaviour in other settings. PMID:25493945

  17. Bundles of Norms About Teen Sex and Pregnancy.

    PubMed

    Mollborn, Stefanie; Sennott, Christie

    2015-09-01

    Teen pregnancy is a cultural battleground in struggles over morality, education, and family. At its heart are norms about teen sex, contraception, pregnancy, and abortion. Analyzing 57 interviews with college students, we found that "bundles" of related norms shaped the messages teens hear. Teens did not think their communities encouraged teen sex or pregnancy, but normative messages differed greatly, with either moral or practical rationalizations. Teens readily identified multiple norms intended to regulate teen sex, contraception, abortion, childbearing, and the sanctioning of teen parents. Beyond influencing teens' behavior, norms shaped teenagers' public portrayals and post hoc justifications of their behavior. Although norm bundles are complex to measure, participants could summarize them succinctly. These bundles and their conflicting behavioral prescriptions create space for human agency in negotiating normative pressures. The norm bundles concept has implications for teen pregnancy prevention policies and can help revitalize social norms for understanding health behaviors. PMID:25387911

  20. A close examination of under-actuated attitude control subsystem design for future satellite missions' life extension

    NASA Astrophysics Data System (ADS)

    Lam, Quang M.; Barkana, Itzhak

    2014-12-01

    Satellite mission life, maintained and prolonged beyond its typical norm of their expectancy, are primarily dictated by the state of health of its Reaction Wheel Assembly (RWA), especially for commercial GEO satellites since torquer bars are no longer applicable while thruster assistant is unacceptable due to pointing accuracy impact during jet firing. The RWA is the primary set of actuators (as compared to thrusters for orbit maintenance and maneuvering) mainly responsible for the satellite mission for accurately and precisely pointing its payloads to the right targets to conduct its mission operations. The RWA consisting of either a set of four in pyramid or three in orthogonal is the primary set of actuators to allow the satellite to achieve accurate and precise pointing of the satellite payloads towards the desired targets. Future space missions will be required to achieve much longer lives and are currently perceived by the GEO satellite community as an "expected norm" of 20 years or longer. Driven by customers' demands/goals and competitive market have challenged Attitude Control Subsystems (ACS) engineers to develop better ACS algorithms to address such an emerging need. There are two main directions to design satellite's under-actuated control subsystem: (1) Attitude Feedback with Zero Momentum Principle and (2) Attitude Control by Angular Velocity Tracking via Small Time Local Controllability concept. Successful applications of these control laws have been largely demonstrated via simulation for the rest to rest case. Limited accuracy and oscillatory behaviors are observed in three axes for non-zero wheel momentum while realistic loss of a wheel scenario (i.e., fully actuated to under-actuated) has not been closely examined! This study revisits the under-actuated control design with detailed set ups of multiple scenarios reflecting real life operating conditions which have put current under-actuated control laws mentioned earlier into a re-evaluation mode since rest to rest case is not adequate to truly represent an on orbit failure of a single wheel. The study is intended to facilitate the ACS community to further develop a more practical under-actuated control law and present a path to extend these current thinking to address a more realistic reconfigurable ACS subject to a dynamic transition from a 3 RWs mode to 2 RWs mode.

  1. "...they should be offering it": a qualitative study to investigate young peoples' attitudes towards chlamydia screening in GP surgeries

    PubMed Central

    2010-01-01

    Background Despite the known health and healthcare costs of untreated chlamydia infection and the efforts of the National Chlamydia Screening Programme (NCSP) to control chlamydia through early detection and treatment of asymptomatic infection, the rates of screening are well below the 2010-2011 target rate of 35%. General Practitioner (GP) surgeries are a key venue within the NCSP however; previous studies indicate that GP surgery staff are concerned that they may offend their patients by offering a screen. This study aimed to identify the attitudes to, and preferences for, chlamydia screening in 15-24 year old men and women attending GP surgeries (the target group). Methods We undertook 36 interviews in six surgeries of differing screening rates. Our participants were 15-24 year olds attending a consultation with a staff member. Data were analysed thematically. Results GP surgeries are acceptable to young people as a venue for opportunistic chlamydia screening and furthermore they think it is the duty of GP surgery staff to offer it. They felt strongly that it is important for surgery staff to have a non-judgemental attitude and they did not want to be singled out as 'needing' a chlamydia screen. Furthermore, our sample reported a strong preference for being offered a screen by staff and providing the sample immediately at the surgery rather than taking home a testing kit. The positive attitude and subjective norms demonstrated by interviewees suggest that young peoples' behaviour would be to accept a screen if it was offered to them. Conclusion Young people attending GP surgeries have a positive attitude towards chlamydia screening and given the right environment are likely to take up the offer in this setting. The right environment involves normalising screening by offering a chlamydia screen to all 15-24 year olds at every interaction with staff, offering screening with a non-judgemental attitude and minimising barriers to screening such as embarrassment. The GP surgery is the ideal place to screen young people for chlamydia as it is not a threatening place for them and our study has shown that they think it is the normal place to go to discuss health matters.

    We developed affective norms for 1,121 Italian words in order to provide researchers with a highly controlled tool for the study of verbal processing. This database was developed from translations of the 1,034 English words present in the Affective Norms for English Words (ANEW; Bradley & Lang, 1999) and from words taken from Italian semantic norms (Montefinese, Ambrosini, Fairfield, & Mammarella, Behavior Research Methods, 45, 440-461, 2013). Participants evaluated valence, arousal, and dominance using the Self-Assessment Manikin (SAM) in a Web survey procedure. Participants also provided evaluations of three subjective psycholinguistic indexes (familiarity, imageability, and concreteness), and five objective psycholinguistic indexes (e.g., word frequency) were also included in the resulting database in order to further characterize the Italian words. We obtained a typical quadratic relation between valence and arousal, in line with previous findings. We also tested the reliability of the present ANEW adaptation for Italian by comparing it to previous affective databases and performing split-half correlations for each variable. We found high split-half correlations within our sample and high correlations between our ratings and those of previous studies, confirming the validity of the adaptation of ANEW for Italian. This database of affective norms provides a tool for future research about the effects of emotion on human cognition. PMID:24150921

    Aims. To establish FeNO norms for healthy Tunisian adults aged 18–60 years and to prospectively assess their reliability. Methods. This was a cross-sectional analytical study. A convenience sample of healthy Tunisian adults was recruited. Subjects responded to a medical questionnaire, and then FeNO levels were measured by an online method (Medisoft, Sorinnes (Dinant), Belgium). Clinical, anthropometric, and plethysmographic data were collected. All analyses were performed on natural logarithm values of FeNO. Results. 257 adults (145 males) were retained. The proposed reference equation to predict FeNO value is lnFeNO (ppb) = 3.47?0.56× height (m). After the predicted FeNO value for a given adult was computed, the upper limit of normal could be obtained by adding 0.60?ppb. The mean ± SD (minimum-maximum) of FeNO (ppb) for the total sample was 13.54 ± 4.87 (5.00–26.00). For Tunisian and Arab adults of any age and height, any FeNO value greater than 26.00?ppb may be considered abnormal. Finally, in an additional group of adults prospectively assessed, we found no adult with a FeNO higher than 26.00?ppb. Conclusion. The present FeNO norms enrich the global repository of FeNO norms that the clinician can use to choose the most appropriate norms. PMID:24991544

  6. Norms and Cones in the Theory of Quantum Entanglement

    E-print Network

    Nathaniel Johnston

    2012-07-05

    There are various notions of positivity for matrices and linear matrix-valued maps that play important roles in quantum information theory. The cones of positive semidefinite matrices and completely positive linear maps, which represent quantum states and quantum channels respectively, are the most ubiquitous positive cones. There are also many natural cones that can been regarded as "more" or "less" positive than these standard examples. In particular, entanglement theory deals with the cones of separable operators and entanglement witnesses, which satisfy very strong and weak positivity properties respectively. Rather complementary to the various cones that arise in entanglement theory are norms. The trace and operator norms for operators and the diamond and completely bounded norms for superoperators are the typical norms that are seen throughout quantum information theory. In this work our main goal is to develop a family of norms that play a role analogous to the cone of entanglement witnesses. We investigate the basic mathematical properties of these norms, including their relationships with other well-known norms, their isometry groups, and their dual norms. We also make the place of these norms in entanglement theory rigorous by showing that entanglement witnesses arise from minimal operator systems, and analogously our norms arise from minimal operator spaces. Finally, we connect the various cones and norms considered here to several seemingly unrelated problems from other areas. We characterize the problem of whether or not non-positive partial transpose bound entangled states exist in terms of one of our norms, and provide evidence in favour of their existence. We also characterize the minimum gate fidelity of a quantum channel, the maximum output purity and its completely bounded counterpart, and the geometric measure of entanglement in terms of these norms.

    Inequitable gender norms in societies and communities negatively contribute to women's sexual and reproductive health. While the need for change in gender norms is well recognized, the task is highly challenging in terms of intervention design, implementation and assessment of impact. This paper describes a methodology for identification of gender norms, the design of community level intervention, community participation and the assessment of intervention impact in a low income, predominately Muslim community of 600,000 people in Mumbai, India. Formative research focused on in-depth interviews with women, men and couples yielding gender normative statements and assessment of community resources to facilitate change. A Gender Equity Scale (GES) based on this formative research was developed and administered annually for a three-year period to random, cross-sectional samples in the intervention and control communities, and to community based, non-governmental organizations (NGO) staff and Imams (religious leaders) in the intervention community. NGO staff disseminated gender oriented messages to their female constituency through their regular outreach activities and through special events and festivals in the community. Imams disseminated gender messages through lectures on social issues for men attending Friday prayers. The results showed that the NGO staff and Imams, assumed more gender equitable attitudes across time. The intervention was associated with a significant improvement in attitudes towards gender equity in the intervention relative to the control community. Men showed a dramatic change in more positive gender attitudes, while women lagged behind in their GES scores. The meaning of these results are explored and the implications assessed for the generalizability of the methodology for other countries, cultures and communities. PMID:26136202

    Attitudes, theorized as behavioral guides, have long been a central focus of research in the social sciences. However, this theorizing reflects primarily Western philosophical views and empirical findings emphasizing the centrality of personal preferences. As a result, the prevalent psychological model of attitudes is a person-centric one. We suggest that incorporating research insights from non-Western sociocultural contexts can significantly enhance attitude theorizing. To this end, we propose an additional model-a normative-contextual model of attitudes. The currently dominant person-centric model emphasizes the centrality of personal preferences, their stability and internal consistency, and their possible interaction with externally imposed norms. In contrast, the normative-contextual model emphasizes that attitudes are always context-contingent and incorporate the views of others and the norms of the situation. In this model, adjustment to norms does not involve an effortful struggle between the authentic self and exogenous forces. Rather, it is the ongoing and reassuring integration of others' views into one's attitudes. According to the normative-contextual model, likely to be a good fit in contexts that foster interdependence and holistic thinking, attitudes need not be personal or necessarily stable and internally consistent and are only functional to the extent that they help one to adjust automatically to different contexts. The fundamental shift in focus offered by the normative-contextual model generates novel hypotheses and highlights new measurement criteria for studying attitudes in non-Western sociocultural contexts. We discuss these theoretical and measurement implications as well as practical implications for health and well-being, habits and behavior change, and global marketing.

    NORM (Naturally Occurring Radioactive Material) has now been found to be associated with many industrial activities that extends far beyond oil and gas production. There are approximately 59 naturally occurring radionuclides that might end up in a train of NORM contamination, which could impact at least 13 industries. It is appropriate and indeed necessary to examine the geological roots of NORM and its concentration in various industries. Impacted NORM industries and their associated problems are presented. Some plant and environmental managers may not even suspect they have NORM problems, because one cannot ``sense`` NORM without instrumentation, until it might be too late for the health and safety of the effected employees and surrounding community. Others want to ``see no evil, hear no evil or speak any evil`` until they are forced into ``reactive`` environmental management, rather than ``proactive`` management. It has been the experience of many that reactive management is far more costly than proactive management.

  18. Public awareness and attitudes toward palliative care in Northern Ireland

    PubMed Central

    2013-01-01

    Background The World Health Organisation recognises palliative care as a global public health issue and this is reflected at strategic level. Despite this, palliative care may not be universally welcomed. Surveys over the last decade have suggested that the general public have a lack of knowledge and negative perceptions towards palliative care. A detailed and comprehensive understanding of public views is needed in order to target education and policy campaigns and to manage future needs, expectations and resourcing of end of life care. The aim of this study was to establish the current levels of awareness and attitudes towards palliative care among the general public in Northern Ireland. Methods A community-based cross-sectional survey with a population of 3,557 individuals aged over 17 years was performed. Information was collected using a structured questionnaire consisting of 17 items. Open questions were subject to content analysis; closed questions were subject to descriptive statistics with inferential testing as appropriate. Results A total of 600 responses were obtained (response rate 17%). Responses indicated limited knowledge about palliative care. Female gender and previous experience influenced awareness in a positive direction. Respondents who worked in healthcare themselves or who had a close relative or friend who had used a palliative care service were more aware of palliative care and the availability of different palliative care services. Findings reveal the preferred place of care was the family home. The main barriers to raising awareness were fear, lack of interaction with health services and perception of lack of resources. A number of strategies to enhance awareness, access and community involvement in palliative care were suggested. Conclusions Public awareness of the concept of palliative care and of service availability remains insufficient for widespread effective and appropriate palliative care to be accepted as the norm. In particular, those without previous family-related experiences lack awareness. This has implications for palliative care service provision and policy. An increased awareness of palliative care is needed, in order to improve knowledge of and access to services when required, empower individuals, involve communities and ultimately to realise the objectives contained within international strategies for palliative and end-of-life care.

    We introduce and study norms in the space of hermitian operators, obtained from base norms in positively generated subspaces. These norms are closely related to discrimination of so-called generalized quantum channels, including quantum states, channels and networks. We further introduce generalized quantum decision problems and show that the maximal average payoff of decision procedures is again given by these norms. We also study optimality of decision procedures, in particular, we obtain a necessary and sufficient condition under which an optimal 1-tester for discrimination of quantum channels exists, such that the input state is maximally entangled.

    We introduce and study norms in the space of hermitian matrices, obtained from base norms in positively generated subspaces. These norms are closely related to discrimination of so-called generalized quantum channels, including quantum states, channels, and networks. We further introduce generalized quantum decision problems and show that the maximal average payoffs of decision procedures are again given by these norms. We also study optimality of decision procedures, in particular, we obtain a necessary and sufficient condition under which an optimal 1-tester for discrimination of quantum channels exists, such that the input state is maximally entangled.

  2. Attitude Sensor Pseudonoise

    2005-01-01

    Even assuming perfect attitude sensors and gyros, sensor measurements on a vibrating spacecraft have apparent errors. These apparent sensor errors, referred to as pseudonoise, arise because gyro and sensor measurements are performed at discrete times. This paper explains the concept of pseudonoise, quantifies its behavior, and discusses the effect of vibrations that are nearly commensurate with measurement periods. Although pseudonoise does not usually affect attitude determination it does affect sensor performance evaluation. Attitude rates are usually computed from differences between pairs of accumulated angle measurements at different times and are considered constant in the periods between measurements. Propagation using these rates does not reproduce exact instantaneous spacecraft attitudes except at the gyro measurement times. Exact sensor measurements will therefore be inconsistent with estimates based on the propagated attitude. This inconsistency produces pseudonoise. The characteristics of pseudonoise were determined using a simple, one-dimensional model of spacecraft vibration. The statistical properties of the deviations of measurements from model truth were determined using this model and a range of different periods of sensor and rate measurements. This analysis indicates that the magnitude of pseudonoise depends on the ratio of the spacecraft vibration period to the time between gyro measurements and can be as much as twice the amplitude of the vibration. In cases where the vibration period and gyro or sensor measurement period are nearly commensurate, unexpected changes in pseudonoise occur.

    Argonne National Laboratory has developed an Internet web site providing access to critical information needed to support decisions on the management and disposal of wastes containing naturally occurring radioactive material (NORM). The NORM Technology Connection web site provides current information on (1) service companies that provide support on NORM issues (e.g., site characterization and remediation, sample analysis, radiation safety training, disposal) and (2) existing applicable NORM regulations and guidelines. A third element of the site is an electronic mail list that allows users to post or respond to questions about the management of NORM. Development of the NORM Technology Connection web site was funded by the U.S. Department of Energy, Office of Fossil Energy. It is hosted and maintained by the Interstate Oil and Gas Compact Commission. The web site is publicly available; access is free, as is participation by any of the service companies.

    Background: In medical practice, the dissatisfaction of patients about medical decisions made by doctors is often regarded as the fuse of doctor-patient conflict. However, a few studies have looked at why there are such dissatisfactions. Objectives: This experimental study aimed to explore the discrepancy between attitude and behavior within medical situations and its interaction with framing description. Patients and Methods: A total of 450 clinical undergraduates were randomly assigned to six groups and investigated using the classic medical decision making problem, which was described either in a positive or a negative frame (2) × decision making behavior\\attitude to risky plan\\attitude to conservative plan (3). Results: A discrepancy between attitude and behavior did exist in medical situations. Regarding medical dilemmas, if the mortality rate was described, subjects had a significant tendency to choose a conservative plan (t = 3.55, P < 0.01) yet if the survival rate was described, there was no such preference (t = -1.48, P > 0.05). However, regardless of the plan chosen by the doctor, the subjects had a significant opposing attitude (P < .05). Framing description had a significant impact on both decision making behavior and attitude (t behavior = -3.24, P < 0.01?t attitude to surgery = 4.08?P < 0.01?t attitude to radiation = -2.15?P < 0.05). Conclusions: A discrepancy of attitude-behavior does exist in medical situations. The framing of a description has an impact on medical decision-making. PMID:25763230

    This research examined whether older adults' attitudes toward computers became more positive as a function of computer experience. The sample comprised 101 community-dwelling older adults aged 57 to 87. The intervention involved a 2-week computer training program in which subjects learned to use a desktop publishing software program. A multidimensional computer attitude measure was used to assess differential attitude change and maintenance of change following training. The results indicated that older adults' computer attitudes are modifiable and that direct computer experience is an effective means of change. Attitude change as a function of training was found for the attitude dimensions targeted by the intervention program: computer comfort and efficacy. In addition, maintenance of attitude change was established for at least two weeks following training. PMID:1624702

    Many statistics lecturers and statistics education researchers are interested to know the perception of their students' attitudes toward statistics during the statistics course. In statistics course, positive attitude toward statistics is a vital because it will be encourage students to get interested in the statistics course and in order to master the core content of the subject matters under study. Although, students who have negative attitudes toward statistics they will feel depressed especially in the given group assignment, at risk for failure, are often highly emotional, and could not move forward. Therefore, this study investigates the students' attitude towards learning statistics. Six latent constructs have been the measurement of students' attitudes toward learning statistic such as affect, cognitive competence, value, difficulty, interest, and effort. The questionnaire was adopted and adapted from the reliable and validate instrument of Survey of Attitudes towards Statistics (SATS). This study is conducted among engineering undergraduate engineering students in the university Malaysia Pahang (UMP). The respondents consist of students who were taking the applied statistics course from different faculties. From the analysis, it is found that the questionnaire is acceptable and the relationships among the constructs has been proposed and investigated. In this case, students show full effort to master the statistics course, feel statistics course enjoyable, have confidence that they have intellectual capacity, and they have more positive attitudes then negative attitudes towards statistics learning. In conclusion in terms of affect, cognitive competence, value, interest and effort construct the positive attitude towards statistics was mostly exhibited. While negative attitudes mostly exhibited by difficulty construct.

    Three times as many cases of measles were reported in the United States in 2014 as in 2013. The reemergence of measles has been linked to a dangerous trend: parents refusing vaccinations for their children. Efforts have been made to counter people's antivaccination attitudes by providing scientific evidence refuting vaccination myths, but these interventions have proven ineffective. This study shows that highlighting factual information about the dangers of communicable diseases can positively impact people's attitudes to vaccination. This method outperformed alternative interventions aimed at undercutting vaccination myths. PMID:26240325

    Work was conducted to develop an extremely low drift rate gyroscope and a very precise star tracker. A proposed relativity satellite will measure very accurately the theoretically predicted 'relativistic' precession of the gyroscope relative to an inertial reference frame provided by the star tracker. Aspects of precision spinning attitude control are discussed together with questions of gyro operation, and the hopping mode for lunar transportation. For the attitude control system of the lunar hopper, a number of control laws were investigated. The studies indicated that some suboptimal controls should be adequate for the system.

    Humans often coordinate their social lives through norms. When a large majority of people are dissatisfied with an existing norm, it seems obvious that they will change it. Often, however, this does not occur. We investigate how a time lag between individual support of a norm change and the change itself hinders such change, related to the critical mass of supporters needed to effectuate the change, and the (im)possibility of communicating about it. To isolate these factors, we utilize a laboratory experiment. As predicted, we find unambiguous effects of time lag on precluding norm change; a higher threshold for a critical mass does so as well. Communication facilitates choosing superior norms but it does not necessarily lead to norm change when the uncertainty on whether there will be a norm change in the future is high. Communication seems to help coordination on actions at the present but not the future. Hence, the uncertainty driven by time lag makes individuals choose the status quo, here the unpopular norm.

    2015-05-01

    Norms shift and emerge in response to technological innovation. One such innovation is Smart Meters - components of Smart Grid energy systems capable of minute-to-minute transmission of consumer electricity use information. We integrate theory from sociological research on social norms and privacy to examine how privacy threats affect the demand for and expectations of norms that emerge in response to new technologies, using Smart Meters as a test case. Results from three vignette experiments suggest that increased threats to privacy created by Smart Meters are likely to provoke strong demand for and expectations of norms opposing the technology and that the strength of these normative rules is at least partly conditional on the context. Privacy concerns vary little with actors' demographic characteristics. These findings contribute to theoretical understanding of norm emergence and have practical implications for implementing privacy protections that effectively address concerns of electricity users.

    Two studies tested the conditions under which an environment (e.g., library, restaurant) raises the relevance of environment-specific social norms (e.g., being quiet, using table manners). As hypothesized, the relevance of such norms is raised when environments are goal relevant ("I am going there later") and when they are humanized with people or the remnants of their presence (e.g., a glass of wine on a table). Two studies show that goal-relevant environments and humanized environments raise the perceived importance of norms (Study 1) and the intention to conform to norms (Study 2). Interestingly, in both studies, these effects reach beyond norms related to the environments used in the studies. PMID:18493030

    2012-01-01

    Succulent cacti are remarkable plants with capabilities to withstand long periods of drought. However, their adult success is contingent on the early seedling stages, when plants are highly susceptible to the environment. To better understand their early coping strategies in a challenging environment, two developmental aspects (anatomy and morphology) in Polaskia chichipe and Echinocactus platyacanthus were studied in the context of developmental reaction norms under drought conditions. The morphology was evaluated using landmark based morphometrics and Principal Component Analysis, which gave three main trends of the variation in each species. The anatomy was quantified as number and area of xylem vessels. The quantitative relationship between morphology and anatomy in early stages of development, as a response to drought was revealed in these two species. Qualitatively, collapsible cells and collapsible parenchyma tissue were observed in seedlings of both species, more often in those subjected to water stress. These tissues were located inside the epidermis, resembling a web of collapsible-cell groups surrounding turgid cells, vascular bundles, and spanned across the pith. Occasionally the groups formed a continuum stretching from the epidermis towards the vasculature. Integrating the morphology and the anatomy in a developmental context as a response to environmental conditions provides a better understanding of the organism's dynamics, adaptation, and plasticity.

    Research indicates that in-group favoritism is prevalent among both adults and children. Although research has documented that individuals do not consistently display an in-group bias, the conditions under which out-group preference exists are not well understood. In this study, participants (N = 462) aged 9 to 16 years judged in-group deviant acts that were either in line with or counter to a generic norm shared by both groups. The findings demonstrated, for the first time, that children preferred out-group over in-group deviance only when the in-group peer's deviance was in line with the generic norm and a threat to their group's identity. Participants justified their disapproval of these deviants by focusing on the need for group cohesion and loyalty, while they signified their approval by spotlighting the need for autonomy. Our findings suggest that children's intergroup attitudes are influenced by how the behavior of their peers matches different levels of group norms. PMID:25888686

    2014-12-01

    According to social identity theory, group members sometimes react to threats to their group's distinctiveness by asserting the distinctiveness of their group. In four studies (n = 261) we tested the hypothesis that heterosexual men with a greater propensity to be threatened by homosexuality would react to egalitarian norms by endorsing biological theories of sexuality. Heterosexual men, but not women, with narrow prototypes of their gender in-group endorsed biological theories the most (Study 1). Heterosexual men with higher gender self-esteem, with heterosexist attitudes, who endorsed traditional gender roles, and with narrow prototypes of their gender in-group, endorsed the biological theories more when egalitarian norms rather than anti-egalitarian norms (Studies 2 and 3) or pro-minority ideologies that emphasized group differences (Study 4) were made salient. These findings show group-level reactive distinctiveness among members of a high-status group in a context of threat to the unique privileges that they once enjoyed. PMID:24131397

    Stephens, Kristen Renee

    The present study was designed to examine the relationship between the criterion variables of science-related attitudes and the predictor variables of gender, self-concept, ethnic origin, mother's occupation, father's occupation, socioeconomic status, and achievement in academically talented students. One hundred and sixty-seven students in grades 11 and 12 from a residential math and science high school in Alabama were administered the Test of Science-Related Attitudes (TOSRA; Fraser, 1981), the Piers-Harris Children's Self-Concept Scale (Piers & Harris, 1969), and a general information questionnaire. Multiple linear regression consisting of canonical correlation, semi-partial correlation, and Manova were used to test the hypotheses of this study. Results indicate that students had favorable attitudes towards science. Significant interactions were found between gender and achievement for the Adoption of Scientific Attitude subtest with high achieving females having more favorable attitudes on this variable followed by low achieving males. Additionally, significant interactions were found between self-concept and achievement and between mother's occupation and father's occupation on the Attitude Toward Normality of Scientists subtest. High achievers with high self-concept obtained the highest scores while low achievers with low self-concept obtained the lowest scores on the Attitude Toward Normality of Scientist subtest. Subjects with fathers and mothers in science occupations obtained the highest scores on the Attitude Toward Normality of Scientist subtest while subjects with a father in a nonscience occupation and a mother in a science occupation obtained the lowest scores. The lowest scores were found in Leisure Interest in Science regardless of gender, self-concept, ethnic origin, mother's occupation, father's occupation, socioeconomic status, or achievement.

  15. Options and cost for disposal of NORM waste.

    SciTech Connect

    Veil, J. A.

    1998-10-22

    Oil field waste containing naturally occurring radioactive material (NORM) is presently disposed of both on the lease site and at off-site commercial disposal facilities. The majority of NORM waste is disposed of through underground injection, most of which presently takes place at a commercial injection facility located in eastern Texas. Several companies offer the service of coming to an operator's site, grinding the NORM waste into a fine particle size, slurrying the waste, and injecting it into the operator's own disposal well. One company is developing a process whereby the radionuclides are dissolved out of the NORM wastes, leaving a nonhazardous oil field waste and a contaminated liquid stream that is injected into the operator's own injection well. Smaller quantities of NORM are disposed of through burial in landfills, encapsulation inside the casing of wells that are being plugged and abandoned, or land spreading. It is difficult to quantify the total cost for disposing of NORM waste. The cost components that must be considered, in addition to the cost of the operation, include analytical costs, transportation costs, container decontamination costs, permitting costs, and long-term liability costs. Current NORM waste disposal costs range from $15/bbl to $420/bbl.

  16. A Family of Norms With Applications In Quantum Information Theory

    2010-08-20

    We consider a family of vector and operator norms defined by the Schmidt decomposition theorem for quantum states. We use these norms to tackle two fundamental problems in quantum information theory: the classification problem for k-positive linear maps and entanglement witnesses, and the existence problem for non-positive partial transpose bound entangled states. We begin with an analysis of the norms, showing that the vector norms can be explicitly calculated, and we derive several inequalities in order to bound the operator norms and compute them in special cases. We then use the norms to establish what appears to be the most general spectral test for k-positivity currently available, showing how it implies several other known tests as well as some new ones. Building on this work, we frame the NPPT bound entangled problem as a concrete problem on a specific limit, specifically that a particular entangled Werner state is bound entangled if and only if a certain norm inequality holds on a given family of projections.

    A novel approach and algorithm have been developed to rapidly detect and localize both moving and static radiological/nuclear (R/N) sources from an airborne platform. Current aerial systems with radiological sensors are limited in their ability to compensate for variable naturally occurring radioactive material (NORM) background. The proposed approach suppresses the effects of NORM background by incorporating additional information to segment the survey area into regions over which the background is likely to be uniform. The method produces pixelated Source Activity Maps (SAMs) of both target and background radionuclide activity over the survey area. The task of producing the SAMs requires (1) the development of a forward model which describes the transformation of radionuclide activity to detector measurements and (2) the solution of the associated inverse problem. The inverse problem is ill-posed as there are typically fewer measurements than unknowns. In addition the measurements are subject to Poisson statistical noise. The Maximum-Likelihood Expectation-Maximization (MLEM) algorithm is used to solve the inverse problem as it is well suited for under-determined problems corrupted by Poisson noise. A priori terrain information is incorporated to segment the reconstruction space into regions within which we constrain NORM background activity to be uniform. Descriptions of the algorithm and examples of performance with and without segmentation on simulated data are presented.

  20. Intimate Partner Violence Attitudes and Experience among Women and Men in Uganda

    Speizer, Ilene S.

    2009-01-01

    This study examines intimate partner violence (IPV) attitudes and experience among women and men in Uganda to inform IPV prevention programs in the region. Nationally representative population-based data from women ages 15–49 and from men ages 15–54 were collected between May and October, 2006 as part of the Uganda Demographic and Health Survey. The survey included questions on women’s and men’s attitudes toward wife beating and information on IPV victimization (women) and perpetration (men). More than half of men and nearly three-quarters of women have attitudes supportive of wife beating in Uganda. More than half of married women report IPV victimization and 40% of married men report perpetration. Women and men who reported witnessing their fathers beating their mothers were more likely to report IPV victimization (perpetration for men). Witnessing violence was also associated with positive attitudes towards wife beating among men. IPV prevention programs need to address the important role of having witnessed wife beating between the mother and the father on men’s subsequent attitudes and behaviors. Women who witnessed wife beating are also the most likely to have supportive attitudes and IPV experience, possibly indicating that their relationship expectations are different than women who did not witness violence. Community-based prevention programs targeting men and women are needed in Uganda and elsewhere in sub-Saharan Africa where gender norms that justify intimate partner violence prevail. PMID:19758975

  1. Does Individualism Help Explain Differences in Employers' Stigmatizing Attitudes Toward Disability Across Chinese and American Cities?

    2011-01-01

    Purpose Stigmatizing attitudes toward people with disabilities can jeopardize such individuals' well-being and recovery through denial of employment and community isolation. By shaping social norms that define group membership, the construct of individualism may partially explain differences in stigmatizing attitudes across cultures. Further, widespread globalization has brought intensely individualistic social practices to certain segments of non-Western cultures. This paper examines whether the construct of individualism can help to explain cross-cultural differences in stigmatizing attitudes observed between American and Chinese employers. Design Employers (N = 879) from Beijing, Hong Kong, and Chicago provided information on their attitudes toward hiring people with disabilities, and Path Analyses were conducted to examine potential mediating relationships. Results Path analyses indicated that vertical individualism, along with perceived responsibility for acquiring a condition, partially mediated the relationship between culture and employers' negative attitudes about job candidates with disabilities. Conclusion These results suggested that greater espousal of competitive and individualist values may drive stigmatizing attitudes across cultures. PMID:21171794

  2. Sex, love and gender norms: sexual life and experience of a group of young people in Ho Chi Minh City, Vietnam.

    2007-03-01

    This paper discusses the impacts of gender norms on the sexual life and experience of a group of young Vietnamese people. It is based on a qualitative study on sexuality and abortion among young people in Ho Chi Minh City, Vietnam. There were two general attitudes towards premarital sex. One view supported young people in a serious, loving relationship engaging in sex before marriage; the other opposed premarital sex because it affected the reputation of girls and their families. These general attitudes were similar to the views on virginity: one group believed strongly in girls maintaining their virginity and the other group emphasised love, emotion and trust, not virginity, as the most important criteria for marriage. Among women there were more supporters than opponents of the traditional view of premarital sex and virginity. Premarital sex was more acceptable for young people in a serious, loving relationship with certain commitment to marriage. Young men considered sex a way to express their love and to become more intimate. Women's view was that premarital sex only occurred within a serious, loving relationship or when there was a serious commitment to marriage. It is clear that young people's sexual life is shaped and constrained by gender norms through political interventions, sexual education and moral judgements. Under the pressure of these norms, young people face many difficulties in order to fulfill a safe and satisfying sexual life. PMID:17382041

    2014-01-01

    Background Recent qualitative studies indicated that physicians interact with pharmaceutical representatives depending on the relative weight of the benefits to the risks and are also influenced by a variety of experiences and circumstances. However, these studies do not provide enough information about if, when, how and why their attitudes and behaviors change over time. Methods and Findings A qualitative study using semi-structured face-to-face individual interviews was conducted on 9 Japanese physicians who attended a symposium on conflicts of interest held in Tokyo. Interviews were designed to explore chronological changes in individual physicians' attitude and behavior concerning relationships with pharmaceutical representatives and factors affecting such changes. Their early interaction with pharmaceutical representatives was passive as physicians were not explicitly aware of the meaning of such interaction. They began to think on their own about how to interact with pharmaceutical representatives as they progressed in their careers. Their attitude toward pharmaceutical representatives changed over time. Factors affecting attitudinal change included work environment (local regulations and job position), role models, views of patients and the public, acquisition of skills in information seeking and evidence-based medicine, and learning about the concepts of professionalism and conflict of interest. However, the change in attitude was not necessarily followed by behavioral change, apparently due to rationalization and conformity to social norms. Conclusions Physicians' attitudes toward relationships with pharmaceutical representatives changed over time and factors affecting such changes were various. Paying attention to these factors and creating new social norms may be both necessary to produce change in behavior consistent with change in attitude. PMID:25238544

    2005-01-01

    This paper provides a survey of modern nonlinear filtering methods for attitude estimation. Early applications relied mostly on the extended Kalman filter for attitude estimation. Since these applications, several new approaches have been developed that have proven to be superior to the extended Kalman filter. Several of these approaches maintain the basic structure of the extended Kalman filter, but employ various modifications in order to provide better convergence or improve other performance characteristics. Examples of such approaches include: filter QUEST, extended QUEST, the super-iterated extended Kalman filter, the interlaced extended Kalman filter, and the second-order Kalman filter. Filters that propagate and update a discrete set of sigma points rather than using linearized equations for the mean and covariance are also reviewed. A two-step approach is discussed with a first-step state that linearizes the measurement model and an iterative second step to recover the desired attitude states. These approaches are all based on the Gaussian assumption that the probability density function is adequately specified by its mean and covariance. Other approaches that do not require this assumption are reviewed, including particle filters and a Bayesian filter based on a non-Gaussian, finite-parameter probability density function on SO(3). Finally, the predictive filter, nonlinear observers and adaptive approaches are shown. The strengths and weaknesses of the various approaches are discussed.

    Materials containing radionuclides of natural origin, which is modified by human made processes and being subject to regulation because of their radioactivity are known as NORM. We present a brief review of the main categories of non-nuclear industries together with the levels of activity concentration in feed raw materials, products and waste, including mechanisms of radioisotope enrichments. The global management of NORM shows a high level of complexity, mainly due to different degrees of radioactivity enhancement and the huge amount of worldwide waste production. The future tendency of guidelines concerning environmental protection will require both a systematic monitoring based on the ever-increasing sampling and high performance of gamma ray spectroscopy. On the ground of these requirements a new low background fully automated high-resolution gamma-ray spectrometer MCA_Rad has been developed. The design of Pb and Cu shielding allowed to reach a background reduction of two order of magnitude with respect to laboratory radioactivity. A severe lowering of manpower cost is obtained through a fully automation system, which enables up to 24 samples to be measured without any human attendance. Two coupled HPGe detectors increase the detection efficiency, performing accurate measurements on sample volume (180 cc) with a reduction of sample transport cost of material. Details of the instrument calibration method are presented. MCA_Rad system can measure in less than one hour a typical NORM sample enriched in U and Th with some hundreds of Bq/kg, with an overall uncertainty less than 5%. Quality control of this method has been tested. Measurements of certified reference materials RGK-1, RGU-2 and RGTh-1 containing concentrations of K, U and Th comparable to NORM have been performed, resulting an overall relative discrepancy of 5% among central values within the reported uncertainty.

    Findings are presented from the first randomized clinical trial that compared changes in alcohol consumption and alcohol-related consequences among college student drinkers from baseline to follow-up across four conditions: (a) a new single component injunctive norms brief motivational intervention (IN-BMI) condition, (b) a single component descriptive norms brief motivational intervention (DN-BMI), (c) a Combined IN and DN brief motivational intervention (Combined-BMI), and (d) assessment-only control. DN-BMI focused on the juxtaposition of personal, perceived, and actual alcohol use by typical same-sex students at your university. INBMI focused on the juxtaposition of personal, perceived, and actual attitudes about alcohol related consequences by the typical same-sex student at your university. Exploratory analyses assessed the effect of IN-BMI and DN-BMI on matched (e.g., the effect of DN-BMI on perceived DN) and mismatched norms (e.g., the effect of DN-BMI on perceived IN). IN-BMI resulted in greater decreases in alcohol use and consequences when delivered alone and in conjunction with DN-BMI compared to the control condition. Further, the Combined-BMI condition reported greater reductions in alcohol use but not consequences compared to the DN condition. Receiving IN-BMI either alone or in combination with DN-BMI produced greater changes in IN perceptions than were produced in the control group. Grounded in norms theory, this study examined how college student problem drinking is affected by both IN-BMI and DN-BMI alone and in combination. We conclude that IN-BMI alone or in combination with DN-BMI is able to modify alcohol use and reduce alcohol related consequences. PMID:26478943

  9. Understanding multiple levels of norms about teen pregnancy and their relationships to teens’ sexual behaviors

    PubMed Central

    Mollborn, Stefanie; Domingue, Benjamin W.; Boardman, Jason D.

    2014-01-01

    Researchers seeking to understand teen sexual behaviors often turn to age norms, but they are difficult to measure quantitatively. Previous work has usually inferred norms from behavioral patterns or measured group-level norms at the individual level, ignoring multiple reference groups. Capitalizing on the multilevel design of the Add Health survey, we measure teen pregnancy norms perceived by teenagers, as well as average norms at the school and peer network levels. School norms predict boys’ perceived norms, while peer network norms predict girls’ perceived norms. Peer network and individually perceived norms against teen pregnancy independently and negatively predict teens’ likelihood of sexual intercourse. Perceived norms against pregnancy predict increased likelihood of contraception among sexually experienced girls, but sexually experienced boys’ contraceptive behavior is more complicated: When both the boy and his peers or school have stronger norms against teen pregnancy he is more likely to contracept, and in the absence of school or peer norms against pregnancy, boys who are embarrassed are less likely to contracept. We conclude that: (1) patterns of behavior cannot adequately operationalize teen pregnancy norms, (2) norms are not simply linked to behaviors through individual perceptions, and (3) norms at different levels can operate independently of each other, interactively, or in opposition. This evidence creates space for conceptualizations of agency, conflict, and change that can lead to progress in understanding age norms and sexual behaviors. PMID:25104920

  11. Registration accuracy and attitude accuracy

    1983-01-01

    Since higher spatial resolution is desired by many applications disciplines coupled with registration in the sub-to-1 pixel range, improved registration accuracy has become necessary. The trend is likely to continue, with image data resolution of 10 meters or less being a routine requirement before the end of this decade. This registration accuracy can only be achieved by the combination of registration and attitude accuracy. This report described the need for improving the attitude accuracy. The relationship between registration accuracy and attitude accuracy is shown, along with criteria for design consideration in establishing adequate attitude accuracy. A precise on-board attitude control system design is essential to provide the attitude accuracy needed to support the subpixel accuracy required for registration of higher resolution images.

    Objective. To examine pharmacy students’ attitudes toward debt. Methods. Two hundred thirteen pharmacy students at the University of Minnesota were surveyed using items designed to assess attitudes toward debt. Factor analysis was performed to identify common themes. Subgroup analysis was performed to examine whether students’ debt-tolerant attitudes varied according to their demographic characteristics, past loan experience, monthly income, and workload. Results. Principal component extraction with varimax rotation identified 3 factor themes accounting for 49.0% of the total variance: tolerant attitudes toward debt (23.5%); contemplation and knowledge about loans (14.3%); and fear of debt (11.2%). Tolerant attitudes toward debt were higher if students were white or if they had had past loan experience. Conclusion. These 3 themes in students’ attitudes toward debt were consistent with those identified in previous research. Pharmacy schools should consider providing a structured financial education to improve student management of debt. PMID:26089561

  13. The attitude accuracy consequences of on-orbit calibration of the Extreme Ultraviolet Explorer attitude sensors by the Flight Dynamics Facility at Goddard Space Flight Center

    NASA Astrophysics Data System (ADS)

    Hashmall, J.; Davis, W.; Harman, R.

    The science mission of the Extreme Ultraviolet Explorer (EUVE) requires attitude solutions with uncertainties of 27, 16.7, 16.7 arcseconds (3 sigma) around the roll, pitch, and yaw axes, respectively. The primary input to the attitude determination process is provided by two NASA standard fixed-head star trackers (FHSTs) and a Teledyne dry rotor inertial reference unit (DRIRU) 2. The attitude determination requirements approach the limits attainable with the FHSTs and DRIRU. The Flight Dynamics Facility (FDF) at Goddard Space Flight Center (GSFC) designed and executed calibration procedures that far exceeded the extent and the data volume of any other FDF-supported mission. The techniques and results of this attempt to obtain attitude accuracies at the limit of sensor capability and the results of analysis of the factors that limit the attitude accuracy are the primary subjects of this paper. The success of the calibration effort is judged by the resulting measurement residuals and comparisons between ground- and onboard-determined attitudes. The FHST star position residuals have been reduced to less tha 4 arcsec per axis -- a value that appears to be limited by the sensor capabilities. The FDF ground system uses a batch least-squares estimator to determine attitude. The EUVE onboard computer (OBC) uses an extended Kalman filter. Currently, there are systematic differences between the two attitude solutions that occasionally exceed the mission requirements for 3 sigma attitude uncertainty. Attempts to understand and reduce these differences are continuing.

    2009-01-01

    In this paper we begin to explore the application of the multiscale flat norm introduced in Morgan and Vixie to shape and image analysis. In particular, we look at the use of the multiscale flat norm signature for the identification of shapes. After briefly reviewing the multiscale flat norm, the L{sup 1}TV functional and the relation between these two, we introduce multiscale signatures that naturally follow from the multiscale flat norm and its components. A numerical method based on the min-cut, max-flow graph-cut is briefly recalled. We suggest using L{sup 2} minimization, rather than the usual Crofton's formula based approximation, for choosing the required weights. The resulting weights have the dual benefits of being analytically computable and of giving more accurate approximations to the anisotropic TV energy. Finally, we demonstrate the usefulness of the signatures on simple shape classification tasks.

    Background Few experimental studies have been conducted on social determinants of pain tolerance. Purpose This study tests a brief, computer-delivered social norm message for increasing pain tolerance. Methods Healthy young adults (N=260; 44 % Caucasian; 27 % Hispanic) were randomly assigned into a 2 (social norm)×2 (challenge) cold pressor study, stratified by gender. They received standard instructions or standard instructions plus a message that contained artifically elevated information about typical performance of others. Results Those receiving a social norm message displayed significantly higher pain tolerance, F(1, 255)=26.95, p<.001, ?p2=.10 and pain threshold F(1, 244)=9.81, p=.002, ?p2=.04, but comparable pain intensity, p>.05.

    The present study examined the unique contributions of protective behavioral strategies and social norms in predicting alcohol-related outcomes. Participants were 363 students from a large public university in the Midwest who reported at least one binge-drinking episode (5+/4+ drinks for men/women in one sitting) in the past 30 days. Data were collected 1/2010–3/2011. We used SEM to test models where protective behavioral strategies (PBS) and social norms were predictors of both alcohol use and alcohol-related problems, after controlling for the effects of gender. Both PBS and descriptive norms had relationships with alcohol use. PBS also had a relationship with alcohol-related problems. Overall, the findings suggest that PBS and social norms have unique associations with distinct alcohol-related outcomes. PMID:25419202

    The Cosmic Background Explorer (COBE) spacecraft was launched in November 1989 by NASA to survey the sky for primordial radiation left from the Big Bang explosion. The success of the mission requires an accurate determination of the spacecraft attitude. While the accuracy of the attitude obtained from the attitude sensors is adequate for two of the experiments, the higher accuracy required by the Diffuse Infrared Background Experiment (DIRBE) is obtained by using the DIRBE instrument as a special type of star sensor. Presented here is an overview of the attitude processing algorithms used at the Cosmology Data Analysis Center (CDAC) and the results obtained from the flight data.

  17. Nursing students' attitudes toward science in the nursing curricula

    NASA Astrophysics Data System (ADS)

    Maroo, Jill Deanne

    The nursing profession combines the art of caregiving with scientific concepts. Nursing students need to learn science in order to start in a nursing program. However, previous research showed that students left the nursing program, stating it included too much science (Andrew et al., 2008). Research has shown a correlation between students' attitudes and their performance in a subject (Osborne, Simon, & Collins, 2003). However, little research exists on the overall attitude of nursing students toward science. At the time of my study there existed no large scale quantitative study on my topic. The purpose of my study was to identify potential obstacles nursing students face, specifically, attitude and motivation toward learning science. According to research the nation will soon face a nursing shortage and students cite the science content as a reason for not completing the nursing program. My study explored nursing students' attitudes toward science and reasons these students are motivated to learn science. I ran a nationwide mixed methods approach with 1,402 participants for the quantitative portion and 4 participants for the qualitative portion. I validated a questionnaire in order to explore nursing students' attitudes toward science, discovered five different attitude scales in that questionnaire and determined what demographic factors provided a statistically significant prediction of a student's score. In addition, I discovered no statistical difference in attitude exists between students who have the option of taking nursing specific courses and those who do not have that option. I discovered in the qualitative interviews that students feel science is necessary in nursing but do not feel nurses are scientists. My study gives a baseline of the current attitude of nursing students toward science and why these students feel the need to learn the science.

    This paper describes the design, construction, testing, and successful flight of the Attitude Sensor Package. The payload was assembled on a standard HITCHHIKER experiment mounting plate, and made extensive use of the carrier's power and data handling capabilities. The side mounted HITCHHIKER version was chosen, since this configuration provided the best viewing conditions for the instruments. The combustion was successfully flown on board Space Shuttle Columbia (STS-52), in October 1992. The payload was one of the 14 experiments of the In-Orbit Technology Demonstration Program (Phase 1) of the European Space Agency.

  6. A Neural Mechanism of Strategic Social Choice under Sanction-Induced Norm Compliance(1,2,3).

    2015-01-01

    In recent years, much has been learned about the representation of subjective value in simple, nonstrategic choices. However, a large fraction of our daily decisions are embedded in social interactions in which value guided decisions require balancing benefits for self against consequences imposed by others in response to our choices. Yet, despite their ubiquity, much less is known about how value computation takes place in strategic social contexts that include the possibility of retribution for norm violations. Here, we used functional magnetic resonance imaging (fMRI) to show that when human subjects face such a context connectivity increases between the temporoparietal junction (TPJ), implicated in the representation of other peoples' thoughts and intentions, and regions of ventromedial prefrontal cortex (vmPFC) that are associated with value computation. In contrast, we find no increase in connectivity between these regions in social nonstrategic cases where decision-makers are immune from retributive monetary punishments from a human partner. Moreover, there was also no increase in TPJ-vmPFC connectivity when the potential punishment was performed by a computer programmed to punish fairness norm violations in the same manner as a human would. Thus, TPJ-vmPFC connectivity is not simply a function of the social or norm enforcing nature of the decision, but rather occurs specifically in situations where subjects make decisions in a social context and strategically consider putative consequences imposed by others.

    A relation between values of a unitarily invariant norm of Hermitian operator before and after action of completely positive map is studied. If the norm is jointly defined on both the input and output Hilbert spaces, one defines a shrinking factor under the restriction of given map to Hermitian operators. As it is shown, for any unitarily invariant norm this shrinking factor is not larger than the maximum of two values for the spectral norm and the trace norm.

    Davidson, A. C.; Grant, M. M. (inventors)

    1973-01-01

    A system for sensing the attitude of a spacecraft includes a pair of optical scanners having a relatively narrow field of view rotating about the spacecraft x-y plane. The spacecraft rotates about its z axis at a relatively high angular velocity while one scanner rotates at low velocity, whereby a panoramic sweep of the entire celestial sphere is derived from the scanner. In the alternative, the scanner rotates at a relatively high angular velocity about the x-y plane while the spacecraft rotates at an extremely low rate or at zero angular velocity relative to its z axis to provide a rotating horizon scan. The positions of the scanners about the x-y plane are read out to assist in a determination of attitude. While the satellite is spinning at a relatively high angular velocity, the angular positions of the bodies detected by the scanners are determined relative to the sun by providing a sun detector having a field of view different from the scanners.

    The Seasat project was a feasibility demonstration of the use of orbital remote sensing for global ocean observation. The satellite was launched in June 1978 and was operated successfully until October 1978. A massive electrical failure occurred in the power system, terminating the mission prematurely. The actual implementation of the Seasat Attitude Determination system and the contents of the attitude data files generated by that system are documented. The deviations from plan caused by the anomalous Sun interference with horizon sensors, inflight calibration of Sun sensor head 2 alignment and horizon sensor biomass, estimation of yaw interpolation parameters, Sun and horizon sensor error sources, and yaw interpolation accuracy are included. Examples are given of flight attitude data from all modes of the Orbital Attitude Control System, of the ground processing effects on attitude data, and of cold cloud effects on pitch, and roll data.

    Female athletes often engage in harmful dietary and weight control practices that can impair bone health and hinder performance. To promote related positive health behavior practices, nutrition educators may be more effective if they understand the osteoporosis knowledge, attitudes, and behaviors among female athletes. A questionnaire including items related to osteoporosis and dietary calcium knowledge, attitudes, and behavioral practices was administered to 114 female collegiate athletes (19.6+/-1.4 years). Self-reported intakes of dairy product consumption were also obtained; subjects were asked how many times per week they drank milk and ate cheese, yogurt, and ice cream. The mean score for osteoporosis knowledge was 7.1+/-1.9 (out of 10 items). The mean score for favorable responses to attitude items was 2.1+/-0.8 (out of 3 items). Correct responses to dietary calcium knowledge items were 2.2+/-0.7 (out of 3 items). On average, subjects consumed 2.4+/-1.6 servings of dairy products per day; 31% of subjects consumed the recommended 3 or more servings per day. Osteoporosis knowledge, osteoporosis attitudes, and dietary calcium knowledge were not correlated (p > .05) with dairy product intake. Because of the importance of achieving a high peak bone mass to prevent osteoporosis, our data suggest that further research is needed regarding other factors that might influence dairy product intake among female athletes.

J Strength Cond Res 30(1): 217-225, 2016-The Wingate Anaerobic Test (WAnT) became one of the most convenient tests used to evaluate anaerobic capacity and the effectiveness of anaerobic training programs for a variety of power sports. However, its use and interpretation as an evaluative measurement are limited because there are few published reference values derived from large numbers of subjects in nonathletic populations. We present reference values for the WAnT in Colombian healthy adults (aged 20-80 years old). The sample comprised 1,873 subjects (64% men) from Cali, Colombia, who were recruited for the study between 2002 and 2012. The 30-second WAnT was performed on a Monark ergometer. The WAnT resistance was set at 0.075 kp·kg body mass (BM). The mean absolute peak power (PP), relative PP normalized to the BM, and the fatigue index (FI%) were calculated using the LMS method (L [curve Box-Cox], M [curve median], and S [curve coefficient of variation]) and expressed as tabulated percentiles from 3 to 97 and as smoothed centile curves (P3, P10, P25, P50, P75, P90, P97). Mean ± SD values for the patients' anthropometric data were 38.1 ± 11.7 years of age, 72.7 ± 14.2 kg weight, 1.68 ± 0.09 m height, and 25.6 ± 4.2 body mass index. Our results show that mean absolute PP value, relative PP relative values normalized to BM, and FI were 527.4 ± 131.7 W, 7.6 ± 2.3 W·kg, and 29.0 ± 15.7%, respectively. Men performed better than women in terms of PP and FI values. Nevertheless, the mean PP decreased with age and sex. Age-specific PP and FI normative values among healthy Colombian adults are defined. A more specific set of reference values is useful for clinicians and researchers studying anaerobic capacity in healthy adults. PMID:26691412

    The aim of the study was to examine the relative importance of young novice drivers' family climate on their driving behavior. A sample of young novice drivers (N=171) between the age of 17 and 24, who held their permanent (or temporary) driver's license for no longer than one year, participated. The questionnaire included items related to the participants' family climate, 3 socio-cognitive determinants (i.e., attitude, locus of control and social norm), and risky driving behaviors. We expected both family climate and the socio-cognitive determinants to exert a direct effect on risky driving. Furthermore we hypothesized that the socio-cognitive determinants would moderate the impact of family climate on risky driving. The results showed that the effect of family climate on risky driving only originated from one single factor (i.e., noncommitment). Besides that, the results confirmed the importance of the three socio-cognitive determinants to the degree that attitude, locus of control, and social norm significantly predicted the self-reported risky driving. In line of what we hypothesized, attitude moderated the relationship between noncommitment and risky driving. Lastly, we found an unexpected three-way interaction which indicated that locus of control moderated the relation between noncommitment and risky driving only when young drivers' attitude was risk-supportive. We recommend scholars and practitioners to take into account the interaction between external sources of influence (such as an individual's family climate) and more personally oriented dispositions (such as an individual's attitude, social norm and locus of control) when trying to explain and change young novices' risky driving.

  2. NICU nurses’ ambivalent attitudes in skin-to-skin care practice

    2014-01-01

    This article illuminates the essence of Neonatal Intensive Care Unit (NICU) nurses’ attitudes in skin-to-skin care (SSC) practice for preterm infants and their parents. Health care providers are in a unique position to influence the dynamic between infants and parents, and SSC affects both partners in the dyad. The design is descriptively phenomenological in terms of reflective lifeworld approach. Eighteen Swedish, Danish, and Norwegian nurses from NICUs offering varied possibilities and extents of SSC participated. NICU nurses’ attitudes in SSC practice are ambivalent. The nurses consider the sensory, wellness, and mutuality experiences to be primary and vital and enact SSC as much as possible. But “as much as possible” is a broad and varied concept, and their attitudes are ambivalent in terms of not always facilitating what they consider to be the optimal caring conditions. The source of NICU nurses’ ambivalent attitudes in SSC practice is a complex interplay of beliefs, norms, and evidence, which have a multidisciplinary basis. The ambivalent attitudes are, to a great extent, the result of the need to balance these multidisciplinary concerns. This needs to be acknowledged in considering SSC practice, as well as acknowledging that clinical judgments concerning optimal SSC depend on parents and infants unlimited access to each other, which NICU nurses can influence.

    The influence of disadvantaged or deprived community on individuals' health risk-behaviors is increasingly being documented in a growing body of literature. However, little is known about the effects of community characteristics on women's sexual attitudes and behaviors. To examine community effects on married women's safer sex negotiation attitudes, we analyzed cross-sectional data from the 2011 Bangladesh Demographic and Health Surveys on a sample of 15,134 married women in 600 communities. We estimated two multilevel logistic regression models. Model 1, which included only individual-level variables, showed that women's autonomy/empowerment, age, and HIV knowledge had significant associations with their safer sex negotiation attitudes. We did not find any socioeconomic status gradient in safer sex negotiation attitudes at the individual level. Adding community-level variables in Model 2 significantly improved the fit of the model. Strikingly, we found that higher community-level poverty was associated with greater positive safer sex negotiation attitudes. Prevailing gender norms and overall women's empowerment in the community also had significant effects. While research on community influences calls for focusing on disadvantaged communities, our research highlights the importance of not underestimating the challenges that married women in economically privileged communities may face in negotiating safer sex. To have sufficient and equitable impact on married women's sexual and reproductive health, sexual and reproductive health promotion policies and programs need to be directed to women in wealthier communities as well.

    The neurocognitive testing of sports concussion for injury management and return-to-play decisions has long been considered the gold standard in evaluation of the injury. Computerized testing batteries are frequently employed, with the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) being the most used of all the current testing platforms to evaluate concussion. ImPACT's clinical report yields four normed composite scores (Verbal Memory, Visual Memory, Visual Motor Speed, and Reaction Time) and another composite score that is not normed but is used as a validity measure (Impulse Control), as well as their corresponding subtest scores, which are not normed. The current study provides normative data on each of the subtests used to calculate the composite scores. Normative data are separated by gender for athletes aged 13 to 21 years old and are stratified by the norm age brackets already employed by the ImPACT. These norms may be helpful in the interpretation of the ImPACT clinical report and further delineation of areas of neurocognitive dysfunction. PMID:25412432

    Study of marketing norm perception among medical representatives is an under-portrayed component that deserves further perusal in the pharmaceutical industry. The purpose of this study is to find out the perception of marketing norms among medical representatives. The research design is quantitative and cross sectional study with medical representatives as unit of analysis. Data is collected from medical representatives (n=300) using a simple random and cluster sampling using a structured questionnaire. Results indicate that there is no difference in the perception of marketing norms among male and female medical representatives. But there is a difference in opinion among domestic and multinational company’s medical representatives. Educational back ground of medical representatives also shows the difference in opinion among medical representatives. Degree holders and multinational company medical representatives have high perception of marketing norms compare to their counterparts. The researchers strongly believe that mandatory training on marketing norms is beneficial in decision making process during the dilemmas in the sales field. PMID:24826035

  7. A Pure L1-norm Principal Component Analysis

    2012-01-01

    The L1 norm has been applied in numerous variations of principal component analysis (PCA). L1-norm PCA is an attractive alternative to traditional L2-based PCA because it can impart robustness in the presence of outliers and is indicated for models where standard Gaussian assumptions about the noise may not apply. Of all the previously-proposed PCA schemes that recast PCA as an optimization problem involving the L1 norm, none provide globally optimal solutions in polynomial time. This paper proposes an L1-norm PCA procedure based on the efficient calculation of the optimal solution of the L1-norm best-fit hyperplane problem. We present a procedure called L1-PCA* based on the application of this idea that fits data to subspaces of successively smaller dimension. The procedure is implemented and tested on a diverse problem suite. Our tests show that L1-PCA* is the indicated procedure in the presence of unbalanced outlier contamination. PMID:23976807

    Objective The Convention on the Rights of the Child has prompted countries to protect children from abuse and exploitation. Exposure to domestic violence and corporal punishment are risk factors in children’s development. This study investigated how women’s attitudes about domestic violence are related to attitudes about corporal punishment, and harsh behaviors toward children, and whether country-wide norms regarding domestic violence and corporal punishment are related to psychological aggression and physical violence toward children. Study design Data were drawn from the Multiple Indicator Cluster Survey, a nationally representative and internationally comparable household survey developed by UNICEF. Measures of domestic violence and discipline were completed by 85,999 female caregivers of children between the ages of 2 and 14 years from families in 25 low- and middle-income countries. Results Mothers who believed that husbands were justified in hitting their wives were more likely to believe that corporal punishment is necessary to rear children, and, in turn, were justified in hitting their wives and that corporal punishment is necessary to rear children were more likely to report that their child had experienced psychological aggression and physical violence. Countrywide norms regarding the acceptability of husbands hitting wives and advisability of corporal punishment moderated the links between mothers’ attitudes and their behaviors toward children. Conclusions Pediatricians can address parents’ psychological aggression and physical violence toward children by discussing parents’ attitudes and behaviors within a framework that incorporates social norms regarding the acceptability of domestic violence and corporal punishment.

    Over the course of the last decade a multitude of studies have investigated the relationship between neural activations and individual human decision-making. Here we asked whether the anatomical features of individual human brains could be used to predict the fundamental preferences of human choosers. To that end, we quantified the risk attitudes of human decision-makers using standard economic tools and quantified the gray matter cortical volume in all brain areas using standard neurobiological tools. Our whole-brain analysis revealed that the gray matter volume of a region in the right posterior parietal cortex was significantly predictive of individual risk attitudes. Participants with higher gray matter volume in this region exhibited less risk aversion. To test the robustness of this finding we examined a second group of participants and used econometric tools to test the ex ante hypothesis that gray matter volume in this area predicts individual risk attitudes. Our finding was confirmed in this second group. Our results, while being silent about causal relationships, identify what might be considered the first stable biomarker for financial risk-attitude. If these results, gathered in a population of midlife northeast American adults, hold in the general population, they will provide constraints on the possible neural mechanisms underlying risk attitudes. The results will also provide a simple measurement of risk attitudes that could be easily extracted from abundance of existing medical brain scans, and could potentially provide a characteristic distribution of these attitudes for policy makers.

  11. Understanding Farmers’ Forecast Use from Their Beliefs, Values, Social Norms, and Perceived Obstacles

    Although the accuracy of weather and climate forecasts is continuously improving and new information retrieved from climate data is adding to the understanding of climate variation, use of the forecasts and climate information by farmers in farming decisions has changed little. This lack of change may result from knowledge barriers and psychological, social, and economic factors that undermine farmer motivation to use forecasts and climate information. According to the theory of planned behavior (TPB), the motivation to use forecasts may arise from personal attitudes, social norms, and perceived control or ability to use forecasts in specific decisions. These attributes are examined using data from a survey designed around the TPB and conducted among farming communities in the region of eastern Nebraska and the western U.S. Corn Belt. There were three major findings: 1) the utility and value of the forecasts for farming decisions as perceived by farmers are, on average, around 3.0 on a 0 7 scale, indicating much room to improve attitudes toward the forecast value. 2) The use of forecasts by farmers to influence decisions is likely affected by several social groups that can provide “expert viewpoints” on forecast use. 3) A major obstacle, next to forecast accuracy, is the perceived identity and reliability of the forecast makers. Given the rapidly increasing number of forecasts in this growing service business, the ambiguous identity of forecast providers may have left farmers confused and may have prevented them from developing both trust in forecasts and skills to use them. These findings shed light on productive avenues for increasing the influence of forecasts, which may lead to greater farming productivity. In addition, this study establishes a set of reference points that can be used for comparisons with future studies to quantify changes in forecast use and influence.

    Zaleski, Adam C.; Aloise-Young, Patricia A.

    2013-01-01

    The present study investigated the importance of the perceived injunctive norm to predict early adolescent cigarette smoking intentions. A total of 271 6th graders completed a survey that included perceived prevalence of friend smoking (descriptive norm), perceptions of friends’ disapproval of smoking (injunctive norm), and future smoking intentions. Participants also listed their five best friends, in which the actual injunctive norm was calculated. Results showed that smoking intentions were significantly correlated with the perceived injunctive norm but not with the actual injunctive norm. Secondly, the perceived injunctive norm predicted an additional 3.4% of variance in smoking intentions above and beyond the perceived descriptive norm. These results demonstrate the importance of the perceived injunctive norm in predicting early adolescent smoking intentions. PMID:24078745

  13. Social norms and illicit behavior: an evolutionary model of compliance.

    2002-09-01

    Economists have viewed the presence of externalities and other market failures as leading to a private equilibrium that would not be Pareto optimal. In the exploitation of common-pool resources, especially biological resources, this would lead to the much-discussed 'tragedy of the commons'. A challenge to this traditional view has emerged from a careful study of the theory and practice of the exploitation of common-pool resources. The existence of a social norm may provide an individual with information on the extent of external costs associated with a behavior, and thus provides an imperfect means of internalizing the external costs. In this paper we propose an evolutionary model of compliance that allows for the existence of a social norm. The impact of the social norm on public policy towards externalities is examined.

    2014-11-29

    In this paper, we consider the problem of discriminating quantum states by local operations and classical communication (LOCC) when an arbitrarily small amount of error is permitted. This paradigm is known as asymptotic state discrimination, and we derive necessary conditions for when two multipartite states of any size can be discriminated perfectly by asymptotic LOCC. We use this new criterion to prove a gap in the LOCC and separable distinguishability norms. We then turn to the operational advantage of using two-way classical communication over one-way communication in LOCC processing. With a simple two-qubit product state ensemble, we demonstrate a strict majorization of the two-way LOCC norm over the one-way norm.

    Programmatic social interventions attempt to produce appropriate social-norm-guided behavior in an open environment. A marriage of applicable psychological theory, appropriate program evaluation theory, and outcome of evaluations of specific social interventions assures the acquisition of cumulative theory and the production of successful social interventions--the marriage permits us to advance knowledge by making use of both success and failures. We briefly review well-established principles within the field of program evaluation, well-established processes involved in changing social norms and social-norm adherence, the outcome of several program evaluations focusing on smoking prevention, pro-environmental behavior, and rape prevention and, using the principle of learning from our failures, examine why these programs often do not perform as expected. Finally, we discuss the promise of learning from our collective experiences to develop a cumulative science of program evaluation and to improve the performance of extant and future interventions.

    2010-01-01

    Two studies examined the relationships among injunctive norms and college student gambling. In study 1 we evaluated the accuracy of perceptions of other students’ approval of gambling and the relationship between perceived approval and gambling behavior. In study 2 we evaluated gambling behavior as a function of perceptions of approval of other students, friends, and family. In study 1, which included 2524 college students, perceptions of other students’ approval of gambling were found to be overestimated and were negatively associated with gambling behavior. The results of study 2, which included 565 college students, replicated the findings of study 1 and revealed positive associations between gambling behavior and perceived approval of friends and family. Results highlight the complexity of injunctive norms and the importance of considering the reference group (e.g., peers, friends, family members) in their evaluation. Results also encourage caution in considering the incorporation of injunctive norms in prevention and intervention approaches. PMID:17394053

    2014-07-01

    In the medical computer tomography (CT) field, total variation (TV), which is the l1-norm of the discrete gradient transform (DGT), is widely used as regularization based on the compressive sensing (CS) theory. To overcome the TV model's disadvantageous tendency of uniformly penalizing the image gradient and over smoothing the low-contrast structures, an iterative algorithm based on the l0-norm optimization of the DGT is proposed. In order to rise to the challenges introduced by the l0-norm DGT, the algorithm uses a pseudo-inverse transform of DGT and adapts an iterative hard thresholding (IHT) algorithm, whose convergence and effective efficiency have been theoretically proven. The simulation demonstrates our conclusions and indicates that the algorithm proposed in this paper can obviously improve the reconstruction quality.

  19. From Abstract to Concrete Norms in Agent Institutions

    Grossi, Davide; Dignum, Frank

    2004-01-01

    Norms specifying constraints over institutions are stated in such a form that allows them to regulate a wide range of situations over time without need for modification. To guarantee this stability, the formulation of norms need to abstract from a variety of concrete aspects, which are instead relevant for the actual operationalization of institutions. If agent institutions are to be built, which comply with a set of abstract requirements, how can those requirements be translated in more concrete constraints the impact of which can be described directly in the institution? In this work we make use of logical methods in order to provide a formal characterization of the translation rules that operate the connection between abstract and concrete norms. On the basis of this characterization, a comprehensive formalization of the notion of institution is also provided.

    2014-01-01

    We evaluated the potential use of RxNorm to provide standardized representations of generic drug name and route of administration to facilitate management of drug lists for clinical decision support (CDS) rules. We found a clear representation of generic drug name but not route of administration. We identified several issues related to data quality, including erroneous or missing defined relationships, and the use of different concept hierarchies to represent the same drug. More importantly, we found extensive semantic precoordination of orthogonal concepts related to route and dose form, which would complicate the use of RxNorm for drug-based CDS. This study demonstrated that while RxNorm is a valuable resource for the standardization of medications used in clinical practice, additional work is required to enhance the terminology so that it can support expanded use cases, such as managing drug lists for CDS.

    2015-09-01

    This paper studies the H2 -norm (or impulse response energy) of fractional transfer functions of implicit type. Stability conditions are first shown to be identical as in rational systems with all poles located in the open left half complex plane. Then, analytical expressions of the H2 -norm are derived for elementary fractional transfer functions of the first and the second kind cascaded with a pure fractional integrator. Next, general boundedness conditions are established in terms of transfer function relative degree. Three illustrative examples are finally proposed. The first one evaluates the quality of a rational approximation of a fractional model of implicit type on the basis of the H2 -norm of the error signal. The second one evaluates the Integral Squared Error of a CRONE control loop and compares it to a classical proportional-derivative controller in a vehicle suspension. Finally, the third one allows to set up an implicit fractional preshaping filter for closed-loop control.

    2015-01-01

    Objectives This study assessed descriptive and injunctive norms, evaluations of alcohol consequences, and acceptability of drinking. Methods Participants were 248 heavy-drinking undergraduates (81.05% female; Mage = 23.45). Results Stronger perceptions of descriptive and injunctive norms for drinking and more positive evaluations of alcohol consequences were positively associated with drinking and the number of drinks considered acceptable. Descriptive and injunctive norms interacted, indicating that injunctive norms were linked with number of acceptable drinks among those with higher descriptive norms. Descriptive norms and evaluations of consequences interacted, indicating that descriptive norms were positively linked with number of acceptable drinks among those with negative evaluations of consequences; however, among those with positive evaluations of consequences, descriptive norms were negatively associated with number of acceptable drinks. Injunctive norms and evaluations of consequences interacted, indicating that injunctive norms were positively associated with number of acceptable drinks, particularly among those with positive evaluations of consequences. A three-way interaction emerged between injunctive and descriptive norms and evaluations of consequences, suggesting that injunctive norms and the number of acceptable drinks were positively associated more strongly among those with negative versus positive evaluations of consequences. Those with higher acceptable drinks also had positive evaluations of consequences and were high in injunctive norms. Conclusions Findings supported hypotheses that norms and evaluations of alcohol consequences would interact with respect to drinking and acceptance of drinking. These examinations have practical utility and may inform development and implementation of interventions and programs targeting alcohol misuse among heavy drinking undergraduates. PMID:25437265

    1994-01-01

    Static attitude estimation and dynamic attitude estimation are used to describe a gradiometer composed of a number of accelerometers that are used to measure a combination of the local gravity gradient and instrument rotation effects. After a series of measures to isolate the gradient, a global mesh of measurements can be obtained that determine the planetary external gravity potential. Orbital and spacecraft models are developed to determine if, when the gravity potential is known, the same measurements, unsupported by any other information can be used to infer the spacecraft attitude.

    A new method is presented for the simultaneous estimation of the attitude of a spacecraft and an N-vector of bias parameters. This method uses a probability distribution function defined on the Cartesian product of SO(3), the group of rotation matrices, and the Euclidean space W N .The Fokker-Planck equation propagates the probability distribution function between measurements, and Bayes s formula incorporates measurement update information. This approach avoids all the issues of singular attitude representations or singular covariance matrices encountered in extended Kalman filters. In addition, the filter has a consistent initialization for a completely unknown initial attitude, owing to the fact that SO(3) is a compact space.

  9. Social norms shift behavioral and neural responses to foods.

    Nook, Erik C; Zaki, Jamil

    2015-07-01

    Obesity contributes to 2.8 million deaths annually, making interventions to promote healthy eating critical. Although preliminary research suggests that social norms influence eating behavior, the underlying psychological and neural mechanisms of such conformity remain unexplored. We used fMRI to investigate whether group norms shift individuals' preferences for foods at both behavioral and neural levels. Hungry participants rated how much they wanted to eat a series of healthy and unhealthy foods and, after each trial, saw ratings that ostensibly represented their peers' preferences. This feedback was manipulated such that peers appeared to prefer each food more than, less than, or as much as participants themselves. After a delay, participants rerated each food. Participants' second ratings shifted to resemble group norms. Initial consensus, as compared to disagreement, with peers produced activity in the nucleus accumbens, a region associated with reward prediction errors. Furthermore, the strength of this activity predicted the extent to which participants' ratings conformed to peer ratings, suggesting that the value associated with consensus drives social influence. Ventromedial prefrontal cortex (vMPFC), a region associated with value computation, initially responded more strongly to unhealthy, as compared to healthy, foods. However, this effect was "overwritten" by group norms. After individuals learned their peers' preferences, vMPFC responses tracked the popularity, but not the healthfulness, of foods. Furthermore, changes in vMPFC activity tracked social influence over behavioral ratings. These data provide evidence that group norms can shift food preferences, supporting the use of norms-based interventions to promote healthy eating. PMID:25671502

    Objective: Perceived descriptive drinking norms often differ from actual norms and are positively related to personal consumption. However, it is not clear how normative perceptions vary with specificity of the reference group. Are drinking norms more accurate and more closely related to drinking behavior as reference group specificity increases? Do these relationships vary as a function of participant demographics? The present study examined the relationship between perceived descriptive norms and drinking behavior by ethnicity (Asian or White), sex, and fraternity/sorority status. Method: Participants were 2,699 (58% female) White (75%) or Asian (25%) undergraduates from two universities who reported their own alcohol use and perceived descriptive norms for eight reference groups: "typical student"; same sex, ethnicity, or fraternity/sorority status; and all combinations of these three factors. Results: Participants generally reported the highest perceived norms for the most distal reference group (typical student), with perceptions becoming more accurate as individuals' similarity to the reference group increased. Despite increased accuracy, participants perceived that all reference groups drank more than was actually the case. Across specific subgroups (fraternity/sorority members and men) different patterns emerged. Fraternity/sorority members reliably reported higher estimates of drinking for reference groups that included fraternity/ sorority status, and, to a lesser extent, men reported higher estimates for reference groups that included men. Conclusions: The results suggest that interventions targeting normative misperceptions may need to provide feedback based on participant demography or group membership. Although reference group-specific feedback may be important for some subgroups, typical student feedback provides the largest normative discrepancy for the majority of students. PMID:21906510

    2013-08-01

    Students' attitudes and anxieties about science were measured by responses to two self-report questionnaires. The cohorts were Danish and American students at the upper secondary- and university-levels. Relationships between and among science attitudes, science anxiety, gender, and nationality were examined. Particular attention was paid to constructivist attitudes about science. These fell into at least three broad conceptual categories: Negativity of Science Toward the Individual, Subjective Construction of Knowledge, and Inherent Bias Against Women. Multigroup confirmatory factor analyses revealed that these dimensions of constructivist attitudes were equally applicable and had the same meaning in both cultures. Gender differences in mean levels of constructivist attitudes were found; these varied across the two cultures. Constructivist beliefs were associated with science anxiety, but in different ways for females and males, and for Danes and Americans. In agreement with earlier studies, females in both the US and Danish cohorts were significantly more science anxious than males, and the gender differences for the Americans were larger than those for the Danes. Findings are discussed in terms of their implications for reducing science anxiety by changing constructivist beliefs.

    The understanding of students' attitude towards science will give a sense of direction when designing pedagogical approaches and lesson packages so that reasons for not liking science is arrested and eventually the nation's need for science oriented workforce is addressed in the future. This study is part of a 3-year research project entitled PbI1@School: A large scale study on the effect of "Physics by Inquiry" pedagogy on Secondary One students' attitude and aptitude in science, involving school, National Institute of Education (NIE) Singapore, University of Washington at Seattle and the Ministry of Education (MOE) of Singapore. The results from a survey conducted on a sample size of 215 secondary 1 students indicate that fun in studying science is a major reason for their interest towards the subject. Those who do not like science dislike the idea of surface learning such as memorizing facts and information. Besides, all these students in our sample appear to be inquisitive. We believe that the teaching and learning system needs to be modified to increase or at least sustain the students' interest in science and capitalize on students' inquisitiveness. Although the results obtained are interesting and give an insight on secondary 1 students' attitude towards science, we intend to carry out a more rigorous study to identify correlations between students' responses for different attitude questions to understand deeply their attitude towards science.

    The relation between attitudes toward men and a number of personality, attitude, and health factors was studied. The 379 respondents (176 men, 203 women) completed the Attitudes Toward Men Scale (A. N. lazzo, 1983) and measures of the Big Five personality factors, conservatism, male bashing, attitudes toward women, sex role, locus of control, and health (including depression, anxiety, and self-esteem). A regression analysis using correlates of attitudes toward men indicated that, among women, femininity and self-esteem were important in predicting attitudes toward men. Among men, masculinity, self-esteem, and age were most important in predicting attitudes toward men. PMID:11577975

    It is known that the minimal output entropy is additive for any product of entanglement breaking (EB) channels. The same is true for the Renyi entropy, where additivity is equivalent to multiplicativity of the $1 \\rightarrow q$ norm for all $q \\ge 1$. In this paper we consider the related question of multiplicativity of the $2 \\rightarrow q$ norm for entanglement breaking channels. We prove that multiplicativity holds in this case for certain classes of EB channels, including both the CQ and QC channels.

Six semi-structured focus groups were first conducted with 48 13-14-year-olds from two schools in Northern Ireland. The salient beliefs elicited were subsequently used to design a TPB-based questionnaire that was then administered to 2021 13-14-year-old pupils (852 males; 1169 females) from 36 post-primary schools to identify the most important determinants of breastfeeding. The results were used to inform the design and implementation of an intervention package that was subsequently evaluated using a cluster randomised controlled trial involving 44 randomly selected schools across Northern Ireland. Questionnaires were administered to 18 intervention and 26 control schools at baseline and again at 1 and 6 months post-intervention to evaluate its effectiveness. Multi-level modelling was employed to analyse the data. The results revealed significant effects on women's intention to breastfeed, ??=?0.208, t(1275)?=?2.715, P?=?0.007; attitudes, ??=?0.223, t(1275)?=?4.655, P?attitudes, ??=?0.231, t(1275)?=?4.211, P?subjective norm, ??=?0.118, t(1275)?=?2.521, P?=?0.012; and knowledge, ??=?0.109, d.f.

  16. Computer ethics education: Impact from societal norms

    Discussions have occurred on the best way to implement the horizontal and vertical integration of education on the social, ethical and professional issues relating to computer science. These discussions have not only included debates on the subject matter and what manner to approach it (i.e. integrated among all computer science courses taught, as a separate required course, or a combination of both), but have also involved debates over who is best qualified to address the subject. What has seldom been addressed, however, is how societal impressions of what is ethical have impacted both those who develop software and those who use it. In light of the experience of such institutions as the U.S. Air Force Academy which recently instituted a program called the Center for Character Development (due to a perceived erosion of the core values of its recruits), should academia and industry expect more from computer scientists than from the population as a whole? It is the integration of ethics courses in the computer science curriculum in light of a general erosion of ethical values in society as a whole that is addressed in this paper.

    Background: The main aim of this study was to accumulate research evidence that introduce validated scales to measure suicidal attitudes and ideation and provide an empirical framework for adopting a relevant assessment tool in studies on suicide and suicidal behaviors. Methods: Medical Subject Headings’ (MeSH) terms were used to search Ovid Medline, PROQUEST, Wiley online library, Science Direct and PubMed for the published articles in English that reported application of an scale to measure suicidal attitudes and ideation from January 1974 onward. Results: Fourteen suicidal attitude scale and 15 scales for assessing suicidal ideation were identified in this systematic review. No gold standard approach was recognized to study suicide related attitudes and ideations. Conclusion: Special focus on generally agreed dimensions of suicidal ideation and attitudes and cross-cultural validation of the introduced scales to be applicable in different ethnic and socially diverse populations could be a promising area of research for scholars.

    This article outlines the development of an instrument to measure pre-service primary teachers' attitudes to teaching mathematics. A trial questionnaire was devised using the set of Fennema-Sherman scales on students' attitudes to the subject mathematics as a model. Analysis of the responses to the questionnaire by 155 student teachers was carried out to develop meaningful attitude scales and to refine the instrument. The end-product is a new instrument which can be used to monitor the attitudes of student teachers. The attitude scales identified in the analysis and built into the final form of the questionnaire are (i) anxiety, (ii) confidence and enjoyment, (iii) desire for recognition and (iv) pressure to conform.

    The Wisconsin card sorting test and the Weigl test are two neuropsychological tools widely used in clinical practice to assess frontal lobe functions. In this study we present norms useful for Italian subjects aged from 15 to 85 years, with 5-17 years of education. Concerning the Wisconsin card sorting test, a new measure of global efficiency (global score) is proposed as well as norms for some well known qualitative aspects of the performance, i.e. perseverative responses, failure to maintain the set and non-perseverative errors. In setting normative values, we followed a statistical methodology (equivalent scores) employed in Italy for other neuropsychological tests, in order to favour the possibility of comparison among these tests. A correlation study between the global score of the Wisconsin card sorting test and the score on the Weigl test was carried out and it emerges that some cognitive aspects are not overlapping in these two measures.

    The questionnaire devised by WHO as a standardized instrument for use across cultures, and modified to suit an African culture, was completed by 104 clinical medical students (male and female) selected at random. After statistical analysis, the results were discussed regarding attitudes (approval/disapproval); perceived availability; social connotation; perceived harmfulness; perceived problems; perceived parental norms; religion; and exposure to use. A significant finding was that 78% of the medical students disapprove of people using all the listed drugs, 11% disapprove slightly and only 11% do not disapprove. PMID:4053969

    2012-08-01

    From mid ´50s onwards, we witness a change of paradigm in the Western world: the expression of a historical shift from modernity to postmodernity. This new era includes a strong influence of the media on the population, a change from a lineal sense of time to a virtual, punctual one, and a flooding of overwhelming amount of information, mostly irrelevant, broadcasted in a de-contextualized, synchronic, fragmented and senseless fashion. This new age is characterized, above all, by the destitution of the State, the meta- institution source of legitimacy of all modern institutions: citizenship, factory, and mainly, School, an essential determinant this last one in the construction process of child subjectivity. Having lost its modeling power, the School loses its modern meaning, becoming thus a mere physical space in which pupils meet, but where general, transcendent rules, norms and values cannot be built, as in fact happened in modern times. According to Corea and Lewkowicz, school becomes an empty shed in which rules have to be built all the time, and become valid only for a particular occasion. These changes necessarily influence child subjectivity, the way they feel, they behave, and they "live" in contemporary society. Pediatricians have to be aware and try to understand these changes, so that we can help children, and, in doing so, to build a better world for them. PMID:22859325

  10. Catholic attitudes toward abortion.

    PubMed

    Smith, T W

    1984-01-01

    In the US attitudes toward abortion in the 1980s seem to have reached a more liberal plateau, much more favored than in the 1960s or earlier, but not longer moving in a liberal direction. Catholic attitudes basically have followed the same trend. Traditionally Catholic support has been slightly lower than Protestant, and both are less inclined to support abortion than Jews or the nonreligious. During the 1970s support among non-black Catholics averaged about 10 percentage points below non-black Protestants. Blacks tend to be anti-abortion and thereby lower support among Protestants as a whole. A comparison of Protestants and Catholics of both races shows fewer religious differences -- about 7 percentage points. There are some indications that this gap may be closing. In 1982, for the 1st time, support for abortions for social reasons, such as poverty, not wanting to marry, or not wanting more children, was as high among Catholics as among Protestants. 1 of the factors contributing to this narrowing gap has been the higher level of support for abortion among younger Catholics. Protestants show little variation on abortion attitudes, with those over age 65 being slightly less supportive. Among Catholics, support drops rapidly with age. This moderate and possibly vanishing difference between Catholics and Protestants contrasts sharply with the official positions of their respective churches. The Catholic Church takes an absolute moral position against abortion, while most Protestant churches take no doctrinaire position on abortion. Several, such as the Unitarians and Episcopalians, lean toward a pro-choice position as a matter of social policy, though fundamentalist sects take strong anti-abortion stances. Few Catholics agree with their church's absolutist anti-abortion position. The big split on abortion comes between what are sometimes termed the "hard" abortion reasons -- mother's health endangered, serious defect in fetus, rape, or incest. Support among Catholics for "hard" reasons ranges from about 80-88%. Abortion for social reasons such as poverty or not wanting additional children ranges from 35-50%. Catholic support for abortion also varies by geographical region, community type, and ethnic group. Support tends to be strongest in the Northeast, in large cities, and among descendants of immigrants from Italy, Eastern Europe, and France. Support is weakest among Catholics in the Southwest, in small towns or rural areas, and among the Irish and Hispanics, especially Mexican-Americans. Among Catholics, many factors cause opinion to deviate from the national average. A 2nd major political implication is the comparative dedication or commitment of supporters and opponents. Analysis of election returns in 1978 in particular failed to demonstrate any measurable anti-abortion vote, but this does not mean that in a particular constituency it could not be made a serious issue.

    Cross-sectional data on the attitudes of Canadian university students, and their parents, indicate attitudes toward homosexuals have become increasingly tolerant and accepting over the past 14 years. Various experimental findings and self-attributions indicate the major cause of this change is increased contact with persons known to be homosexuals. Other factors, such as the evidence for biological origins of sexual orientation, and boomerang effects from hostility toward homosexuals also appear to have played a role. PMID:12013575

    Abstract In this paper, an approach to increase the degree of autonomy of flight software is proposed. We describe an enhancement of the Attitude Determination and Control System by augmenting it with self-calibration capability. Conventional attitude estimation and control algorithms are combined with higher level decision making and machine learning algorithms in order to deal with the uncertainty and complexity of the problem.

  14. An exploratory cluster randomised trial of a university halls of residence based social norms marketing campaign to reduce alcohol consumption among 1st year students

    PubMed Central

    2013-01-01

    Aims This exploratory trial examines the feasibility of implementing a social norms marketing campaign to reduce student drinking in universities in Wales, and evaluating it using cluster randomised trial methodology. Methods Fifty residence halls in 4 universities in Wales were randomly assigned to intervention or control arms. Web and paper surveys were distributed to students within these halls (n?=?3800), assessing exposure/contamination, recall of and evaluative responses to intervention messages, perceived drinking norms and personal drinking behaviour. Measures included the Drinking Norms Rating Form, the Daily Drinking Questionnaire and AUDIT-C. Results A response rate of 15% (n?=?554) was achieved, varying substantially between sites. Intervention posters were seen by 80% and 43% of students in intervention and control halls respectively, with most remaining materials seen by a minority in both groups. Intervention messages were rated as credible and relevant by little more than half of students, though fewer felt they would influence their behaviour, with lighter drinkers more likely to perceive messages as credible. No differences in perceived norms were observed between intervention and control groups. Students reporting having seen intervention materials reported lower descriptive and injunctive norms than those who did not. Conclusions Attention is needed to enhancing exposure, credibility and perceived relevance of intervention messages, particularly among heavier drinkers, before definitive evaluation can be recommended. A definitive evaluation would need to consider how it would achieve sufficient response rates, whilst hall-level cluster randomisation appears subject to a significant degree of contamination.

  15. Effects of everyday romantic goal pursuit on women's attitudes toward math and science.

    The present research examined the impact of everyday romantic goal strivings on women's attitudes toward science, technology, engineering, and math (STEM). It was hypothesized that women may distance themselves from STEM when the goal to be romantically desirable is activated because pursuing intelligence goals in masculine domains (i.e., STEM) conflicts with pursuing romantic goals associated with traditional romantic scripts and gender norms. Consistent with hypotheses, women, but not men, who viewed images (Study 1) or overheard conversations (Studies 2a-2b) related to romantic goals reported less positive attitudes toward STEM and less preference for majoring in math/science compared to other disciplines. On days when women pursued romantic goals, the more romantic activities they engaged in and the more desirable they felt, but the fewer math activities they engaged in. Furthermore, women's previous day romantic goal strivings predicted feeling more desirable but being less invested in math on the following day (Study 3). PMID:21617021

  19. Evolving norms at the intersection of health and trade.

    2014-06-01

    There has been growing tension at the intersection of health and economic policy making as global governance has increased across sectors. This tension has been particularly evident between tobacco control and trade policy, as the international norms that frame them?--?particularly the Framework Convention on Tobacco Control and the World Trade Organization (WTO)?--?have continued to institutionalize. Using five case studies of major tobacco-related trade disputes from the principal multilateral system of trade governance?--?the WTO/General Agreement on Tariffs and Trade?--?we trace the evolution of these interacting norms over nearly twenty-five years. Our analytic framework focuses on the actors that advance, defend, and challenge these norms. We find that an increasingly broad network, which includes governments, intergovernmental organizations, nongovernmental organizations, and members of the epistemic community, is playing a more active role in seeking to resolve these tensions. Moreover, key economic actors are beginning to incorporate health more actively into their messaging and activities. We also demonstrate that the most recent resonant messages reflect a more nuanced integration of the two norms. The tobacco control example has direct relevance to related policy areas, including environment, safety, access to medicines, diet, and alcohol. PMID:24603086
