OBJECTIVES: To identify trends over 12 years in the prevalence of bullying and associated victimization among adolescents in North American and European countries. METHODS: Cross-sectional self-report surveys were obtained from nationally representative samples of 11-15 year old school children in...... 21 countries in 1993/94 and in 27 countries in each of 1997/98, 2001/02 and 2005/06. Measures included involvement in bullying as either a perpetrator and/or victim. RESULTS: Consistent decreases in the prevalence of bullying were reported between 1993/94 to 2005/06 in most countries. Geographic...... patterns show consistent decreases in bullying in Western European countries and in most Eastern European countries. An increase or no change in prevalence was evident in almost all English speaking countries participating in the study (England, Scotland, Wales, Ireland and Canada, but not in the USA...

SUMMARYThe weekly number of dengue cases in Peru, South America, stratified by province for the period 1994-2006 were analysed in conjunction with associated demographic, geographic and climatological data. Estimates of the reproduction number, moderately correlated with population size (Spearman rho=0.28, P=0.03), had a median of 1.76 (IQR 0.83-4.46). The distributions of dengue attack rates and epidemic durations follow power-law (Pareto) distributions (coefficient of determination >85%, P<0.004). Spatial heterogeneity of attack rates was highest in coastal areas followed by mountain and jungle areas. Our findings suggest a hierarchy of transmission events during the large 2000-2001 epidemic from large to small population areas when serotypes DEN-3 and DEN-4 were first identified (Spearman rho=-0.43, P=0.03). The need for spatial and temporal dengue epidemic data with a high degree of resolution not only increases our understanding of the dynamics of dengue but will also generate new hypotheses and provide a platform for testing innovative control policies.

According to the permanent income / life-cycle hypothesis (PILCH), under standard preferences anticipated changes in employment status should not affect the changes in consumption. In this paper, we investigate the consumption behaviour of individuals who lose their jobs and those who find a job. For a representative sample of American households anticipated changes between employment and unemployment states are identified using monthly transition expectations. Firstly, it is shown that expec...
It is well recognized that CT scan is very useful in the early diagnosis of cerebral palsy. The author has studied this time the CT scan findings of cerebral palsy children in their relations to the type of palsy, cause of palsy, complications in the central nervous system, and prognosis of behaviour development, in order to predict the prognosis of behaviour development. Dilatation of the contralateral cerebral ventricle was found in 82 % of hemiplegic type. Abnormal EEG was found in 73 %, but their behaviour development was satisfactory, with good development of speech regardless to the side of palsy. This might be helped by compensational function of the brain due to plasticity. Diplegia presented bilateral moderate dilatation of ventricles with favorable prognosis. Tetraplegia was caused mostly by asphyxia or congenital anomaly and revealed marked dilatation of ventricles or severe cortical atrophy. Some cases presented diffuse cortical low-density, often associated with abnormal EEG, and their prognosis was worst. Athetosis had normal CT finding or mild ventricular dilatation, but all cases of ataxia presented normal CT findings. Hypotonia had mild ventricular dilatation. Two of three mixed type cases had normal CT findings and another had mild ventricular dilatation. No correlation was found between ventricular dilatation and behaviour development, but statistically significant difference was found in the cases with 30 % or more Evans' ratio (P < 0.05). Prognosis of severe ventricular dilatation cases was poor.

Full Text Available We review the literature on the relation between narcissism and consumer behaviour. Consumer behaviour is sometimes guided by self-related motives (e.g., self-enhancement rather than by rational economic considerations. Narcissism is a case in point. This personality trait reflects a self-centred, self-aggrandizing, dominant, and manipulative orientation. Narcissists are characterised by exhibitionism and vanity, and they see themselves as superior and entitled. To validate their grandiose self-image, narcissists purchase high-prestige products (i.e., luxurious, exclusive, flashy, show greater interest in the symbolic than utilitarian value of products, and distinguish themselves positively from others via their materialistic possessions. Our review lays the foundation for a novel methodological approach in which we explore how narcissism influences eye movement behaviour during consumer decision-making. We conclude with a description of our experimental paradigm and report preliminary results. Our findings will provide insight into the mechanisms underlying narcissists’ conspicuous purchases. They will also likely have implications for theories of personality, consumer behaviour, marketing, advertising, and visual cognition.

Full Text Available Archaeology is not only about describing things; we also seek to understand what we find. Sometimes a find can seem puzzling, unexpected in the context in question. It is argued here that evidence of non-Christian elements of religiosity in a historical context can constitute such surprising finds. These finds become less confusing in the light of other sources, such as folklore accounts and historical records. Still, archaeology can offer something not accessible to other disciplines. This paper discusses the phenomenon of folk religion, and the ways that we can take to find the meanings behind the material remains of practices, which may perhaps seem odd to us. A multidisciplinary approach is favoured, and the contribution of archaeology is crucial in gaining information about past practices. The paper also offers a short survey of some archaeological approaches to questions of folk religion. Another issue addressed is why we might be surprised to find evidence of ‘strange’ practices in historical contexts. It is suggested here that historical constructs about the ‘civilising’ effects of Christianity, Reformation, and Enlightenment, respectively, have affected the way that religiosity has been seen in the context of historical Europe.

Full Text Available Abstract Background Although several studies have reported findings concerning the association between smoking and emotional/behavioural problems, little research has investigated this association after controlling for confounding factors which have been found to be significantly correlated with both cigarette smoking and emotional/behavioural problems and may have a strong effect on the relationship between adolescents' mental health and smoking. The present study attempted to assess the association between adolescents' smoking status and their emotional/behavioural problems after controlling for a number of possible confounders (i.e. age, gender, parental smoking status, exposure to family smoking, family socioeconomic status, adolescents' leisure time in a Greek nation-wide school-based sample. Methods Participants completed a questionnaire which retrieved information about age, gender, family socioeconomic status, smoking status, parental smoking, adolescents' leisure time and emotional/behavioural problems. Data were modelled using multiple logistic regression analysis with adolescents' smoking status as the dependent variable. Results A total of 1194 (i.e. 63% response rate of self-reported questionnaires (40.1% boys, 59.9% girls; 12-18 years old were returned. Data from 1030 participants with full data were analyzed. Cigarette smoking was strongly associated with higher levels of emotional/behavioural problems (p Conclusions This study supports the association between smoking and emotional/behavioural problems among adolescents. Addressing adolescents' needs regarding their emotional/behavioural health could be helpful in the development of effective anti-smoking strategies in school environment and elsewhere.

Mindfulness and mindful eating have become popular in recent years. In this review, we first explore what mindfulness is in the context of psychological research, and why it offers promise for eating behaviours and weight loss. Second, we review the main empirical findings for weight loss in mindfulness-based intervention programmes. Third, contradictions in the findings are explored in more depth, and suggestions are made regarding why they may be occurring. Fourth, the benefits of adding self-compassion (and compassion) training to mindfulness practise to assist weight loss is discussed. Finally, the limitations of the research literature (and possible solutions) are explored. Overall, it is concluded that while mindfulness meditations that specifically focus on eating may be extremely helpful in promoting better eating behaviours, and assist in weight regulation, work is still needed to make such interventions appeal to a wider audience.

Depression has been described as a process of behavioural withdrawal from overwhelming aversive stressors, and which manifests itself in the diagnostic symptomatology for Major Depressive Disorder (MDD). The underlying neurobiological pathways to that behavioural withdrawal are suggested to include greater activation in the right vs the left frontal lobes, described as frontal EEG asymmetry. However, despite a previous meta-analysis that provided overall support for this EEG asymmetry hypothesis, inconsistencies and several methodological confounds exist. The current review examines the literature on this issue, identifies inconsistencies in findings and discusses several key research issues that require addressing for this field to move towards a defensible theoretical model of depression and EEG asymmetry. In particular, the position of EEG asymmetry in the brain, measurement of severity and symptoms profiles of depression, and the effects of gender are considered as potential avenues to more accurately define the specific nature of the depression-EEG asymmetry association.

During this 13-year period, solar radiation shows increasing values, averaging 0.5 W m-2 y-1, at the nunatak...... and decreasing values, averaging 1.4 W m-2 y-1, at the coast. The mean annual solar radiation at Station Coast is 102 W m-2 y-1, which is about 10% lower than at Station Nunatak, and is probably caused by increasing and higher percentages of dense clouds and sea fog in the coastal area. The mean...... annual air temperature is increasing by 0.10ºC y-1 at the nunatak and by 0.05ºC y-1 at the coast, extending the thawing periods by about 50 days and 5 days, respectively.

Full Text Available BACKGROUND: Evidence based and gender specific knowledge about sickness absence following coronary revascularisation is lacking. The objective was to investigate sickness absence after a first coronary artery bypass grafting (CABG or percutaneous coronary intervention (PCI among women and men in a national Swedish study. MATERIALS AND METHODS: All patients 30-63 years of age, who underwent a first CABG (n = 22,985, 16% women or PCI (40,891, 22% women in Sweden between 1994 and 2006 were included. Information on sickness absence, co-morbidity, and other patient characteristics was obtained from national registers. Long-term sickness absence (LTSA was defined as >180 and >90 sick-leave days in the first sick-leave spell following CABG and PCI, respectively. Prevalence ratio (PR and 95% confidence interval (CI of LTSA were calculated. FINDINGS: LTSA followed the interventions in 41% and 36% for CABG and PCI patients, respectively. Women had more often LTSA compared with men, (CABG PR = 1.23: 95% CI 1.19-1.28 and PCI PR = 1.19; 95% CI 1.16-1.23. A history of sickness absence the year before the intervention increased the risk for LTSA after the intervention in both genders. Among women, older age, or being self employed or unemployed was associated with a lower risk for LTSA. Among men previous cardiovascular disease, diabetes and low socio-economic position increased the risk. During the observation period, there was no change in sickness absence rates among PCI patients but an increase among CABG patients adjusting for patient characteristics. CONCLUSION: This national study covering a 13-year period shows that long-term sickness absence following coronary revascularisation is common in Sweden, especially among women, and is associated with socio-economic position, co-morbidity, and sickness absence during the year before the intervention. Gender specific scientific knowledge about use and effects of sickness absence following coronary

In this cross-sectional study, it is tested, if such findings might also apply to students in lower secondary schools (7th- to 9th-grades. In a sample of 493 students, it was found, that the level of antisocial behaviour within the personal peer environment (mean of all classmate`s behaviour without individual value significantly predicts individual aggressive-oppositional and delinquent-criminal behaviours. This remains true, even when controlling for sex, antisocial attitudes, academic track and grade. Interaction effects show a special impact of the classroom peer environment on the behaviour of boys and students with positive attitudes towards delinquent-criminal behaviour. The results of this study indicate a significant relationship between classmates` and individual behaviour. They are discussed in the light of research on class composition and the question of adequate educational placements for students with antisocial behaviours.

We describe demographic, clinical, laboratory and aetiological findings in 93 consecutive patients with rapid eye movement (REM) sleep behaviour disorder (RBD), which consists of excessive motor activity during dreaming in association with loss of skeletal muscle atonia of REM sleep. The patients were seen at the Mayo Sleep Disorders Center between January 1, 1991 and July 31, 1995. Eighty-one patients (87%) were male. The mean age of RBD onset was 60.9 years (range 36-84 years) and the mean age at presentation was 64.4 years (37-85 years). Thirty-two per cent of patients had injured themselves and 64% had assaulted their spouses. Subdural haematomas occurred in two patients. Dream content was altered and involved defence of the sleeper against attack in 87%. The frequency of nocturnal events decreased with time in seven untreated patients with neurodegenerative disease. MRI or CT head scans were performed in 56% of patients. Although four scans showed brainstem pathology, all of these patients had apparently unrelated neurodegenerative diseases known to be associated with RBD. Neurological disorders were present in 57% of patients; Parkinson's disease, dementia without parkinsonism and multiple system atrophy accounted for all but 14% of these. RBD developed before parkinsonism in 52% of the patients with Parkinson's disease. Five of the 14 patients with multiple system atrophy were female, and thus the strong male predominance in RBD is less evident in this condition. Psychiatric disorders, drug use or drug withdrawal were rarely causally related to RBD. Clonazepam treatment of RBD was completely or partially successful in 87% of the patients who used the drug. We conclude that RBD is a well-defined condition and that descriptions from different centres are fairly consistent. It is commonest in elderly males and may result in serious morbidity to patients and bed partners. There is a strong relationship to neurodegenerative disease, especially Parkinson's disease

Many studies have shown that psychophysiological parameters of processing emotional stimuli are associated with different personality traits in children, adolescents, and adults. Individuals with low autonomic baseline arousal, low orienting reaction, accelerated habituation, and reduced excitability particularly to punishing stimuli are characterised by a reduced experience of anxiety, decreased behaviour inhibition, and increased sensation seeking. These characteristics seem to raise the likelihood of dis-social behavior and are perceived as prognostically favourable for the development of antisocial personality disorders in childhood and adolescence. In contrast, an increased disposition towards anxiety, which is associated with increased autonomic reactivity, is recognised as a protective factor. Current data have shown that through special training, child and adolescent autonomic reactivity could be enhanced. Due to its versatility, this biological marker might be used for prevention in children at greater risk of developing antisocial behaviour. PMID:16489425

This study aimed to assess dietary behaviours during pregnancy among first-time mothers, and to investigate the relationships between these behaviours and demographic characteristics, so that appropriate dietary intervention strategies for pregnant women can be developed. Method An analysis of cross-sectional survey was conducted using data from 409 first-time mothers at 26-36 weeks of pregnancy, who participated in the Healthy Beginnings Trial conducted in southwestern Sydney, Australia. Dietary behaviours, including consumption of vegetables, fruit, water, milk, soft drinks, processed meat products, fast foods/take away and chips, were assessed using the New South Wales Health Survey questionnaire through face-to-face interviews. Factors associated with dietary behaviours were determined by logistic regression modeling. Log-binomial regression was used to calculate adjusted risk ratios (ARR. Results Only 7% of mothers reported meeting the recommended vegetable consumption and 13% reported meeting the recommended fruit consumption. Mean and median intakes per day were 2.3 (SD 1.3 and 2 serves of vegetables, and 2.1 (SD 1.4 and 2 serves of fruit respectively. About one fifth of mothers (21% reported drinking 2 cups (500 ml or more of soft drink per day and 12% reported consuming more than 2 meals or snacks from fast-food or takeaway outlets per week. A small percentage of mothers (5% had experienced food insecurity over the past 12 months. There were significant inverse associations between water and soft drink consumption (Spearman's ρ -0.20, P Conclusions There were low reported levels of vegetable and fruit consumption and high reported levels of soft drink and takeaway/fast food consumption among pregnant women. Dietary interventions to prevent adverse health consequences need to be tailored to meet the needs of pregnant women

Parenting style may have a role in the development of young children's dietary behaviour, and a better understanding of parenting style may lead to better-targeted childhood obesity prevention interventions. This study aimed to investigate the association of parental self-efficacy, parenting style and dietary behaviour of young children. A cross-sectional study with 242 first-time mothers and their children was conducted using the data from the Healthy Beginnings Trial undertaken in one of the most socially and economically disadvantaged areas of south-western Sydney, in 2007-2010. Parental self-efficacy, parenting style (warmth and hostility) and children's dietary behaviours (consumption of vegetables, fruit, soft-drink and snacks) were assessed by face-to-face interviews with participating mothers in the control group when their children were 2 years old. Logistic regression analysis was conducted to examine the association between parenting style and the child's dietary behaviour. Mothers with higher levels of global parental self-efficacy and self-efficacy for an infant were more likely to report their children had 2 serves of vegetables per day, with odds ratio (OR) 2.40 (95%CI 1.35-4.27, P=0.003) and OR 1.88 (95%CI 1.06-3.36, P=0.03), respectively. A higher level of global parental self-efficacy or self-efficacy for an infant was significantly associated with having 2 serves of fruit per day with adjusted odds ratio (AOR) 2.46 (95%CI 1.35-4.48, P=0.003) and AOR 1.85 (95%CI 1.00-3.41, P=0.048), respectively, after adjusting for annual household income. Mothers with a higher level of parental warmth were more likely to report their children had 2 serves of vegetable per day with OR 1.85 (95%CI 1.06-3.25, P=0.03). Parental self-efficacy and parenting style were associated, cross-sectionally, with important children's dietary behaviours. Interventions which target parental self-efficacy and parenting style may improve eating habits of young children, and

Full Text Available Research exploring the role of spatial frequencies in rapid stimulus detection and categorisation report flexible reliance on specific spatial frequency bands. Here, through a set of behavioural and magnetoencephalography (MEG experiments, we investigated the role of low spatial frequency (LSF(<8 cpf and high spatial frequency (HSF(>25 cpf information during the categorisation of faces and places. Reaction time measures revealed significantly faster categorisation of faces driven by LSF information, while rapid categorisation of places was facilitated by HSF information. The MEG study showed significantly earlier latency of the M170 component for LSF faces compared to HSF faces. Moreover, the M170 amplitude was larger for LSF faces than for LSF places, whereas the reverse pattern was evident for HSF faces and places. These results suggest that spatial frequency modulates the processing of category specific information for faces and places.

Several studies have supported the efficacy and predictive utility of the Theory of Planned Behaviour (TPB; Ajzen, 1991) in explaining a variety of behaviours including physical activity. However, the relative contribution of the theory’s components in describing intention and behaviour may differ depending on the context, time and population being studied. Such evidence is necessary to inform exercise advice and interventions aimed at pregnant women. The purpose of this study was therefore...

While many studies confirm the association between HIV, alcohol and injecting drug use by female sex workers (FSWs), little is known about their use of marijuana, khat and other substances and the association of these substances with HIV, risky sexual behaviour, and sexual violence. To better understand this association, data were analysed from a cross-sectional, behavioural survey of 297 FSWs in Mombasa, a well-known tourist destination and the second largest port in Africa and capital city of the Coast Province in Kenya. Among the FSWs, lifetime use of different substances was reported by 91% for alcohol, 71% for khat, 34% for marijuana, and 6% for heroin, cocaine, glue or petrol. The majority (79%) used more than one substance, and multiple-substance use was reported by all respondents who ever used marijuana, heroin, cocaine, glue and petrol. The risk of HIV acquisition was perceived as medium to high by 41% of respondents, 75% of whom attributed this risk to multiple partners. Sexual violence was reported by 48% of respondents, and 30% indicated that this happened several times. Despite HIV prevention programmes targeting FSWs in Mombasa, most of them continue to engage in risky sexual behaviours. This suggests that harm reduction strategies for substance use should be coupled with efforts to promote consistent condom use and partner reduction. PMID:21409306

Stereotypies are invariant and repetitive behaviour patterns that seemingly have no function, which tend to develop in captive animals faced with insoluble problems and may be indicative of reduced welfare. A 4 year prospective study of the factors influencing the development of stereotypic and redirected behaviours (abnormal behaviour) in a population of 225 young Thoroughbred and part-Thoroughbred horses was conducted between 1995 and 1999. Abnormal behaviour affected 34.7% of the population. Multivariable analysis showed that foals of low- or middle-ranking mares were less likely to develop abnormal behaviour than foals of dominant mares (rate ratio (RR) 0.23, P<0.01; RR 0.48, P<0.01, respectively). Weaning by confinement in a stable or barn was associated with an increased rate of development of abnormal behaviour, compared with paddock-weaning (RR 2.19, P<0.05), and housing in barns, rather than at grass after weaning, was associated with a further increase (RR 2.54, P<0.01). Specific stereotypic and redirected behaviours were then considered as separate outcomes. Crib-biting was initiated by 10.5% of horses at median age 20 weeks, weaving by 4.6% of horses at median age 60 weeks, box-walking by 2.3% of horses at median age 64 weeks and wood-chewing by 30.3% of horses at median age 30 weeks. Wood-chewing developed at a lower rate in horses born to subordinate or mid-ranking mares than in horses born to dominant mares (RR 0.29, P<0.01; RR 0.41, P<0.01, respectively), and at a higher rate in horses kept in barns or stables rather than at grass after weaning (RR 4.49, P<0.001; RR 1A6, P<0.001, respectively). Feeding concentrates after weaning was associated with a 4-fold increase in the rate of development of crib-biting (RR 4.12, P = 0.02). The results of this study support the idea that simple changes in feeding, housing and weaning practices could substantially lower the incidence of abnormal behaviour in young horses. PMID:12357996

Studies applying social cognitive frameworks such as the health belief model and the theory of reasoned action to HIV-prevention are reviewed. These models suggest that appropriate beliefs, attitudes, social norms, intentions and perceived self-efficacy are sufficient psychological conditions for safer sexual behaviour. Limitations inherent in these accounts are identified and additional factors which need to be incorporated in psychological models and health education programmes are highlighted. These include, the motivational complexity of sexual behaviour, the emotional and arousal states in which it is enacted, the difficulties of planning what is regarded as spontaneous interaction and contextual factors which can undermine HIV-preventive intentions.

The aim of this paper is to identify dimensions of leadership in the Slovak organizational environment. For this, the GLOBE (Global Leadership and Organization Behaviour Effectiveness) study was utilized as an empirical base. The results obtained from the research - generated via a factor analysis – have proved that implicit leadership theories do indeed exist and can be specifically defined; and these leadership factors differ from the international sample of implicit leadership theories.

Investments in renewable energy (RE) technologies are regarded with increasing interest as an effective means to stimulate growth and accelerate the recovery from the recent financial crisis. Yet, despite their appeal, and the numerous policies implemented to promote these technologies, the diffusion of RE projects remains somehow below expectations. This limited penetration is also due to a lack of appropriate financing and to a certain reluctance to invest in these technologies. In order to shed light on this phenomenon, in this paper we examine the decision making process underlying investments in RE technologies. We propose and test a conceptual model that examines the structural and behavioural factors affecting the investors decisions as well as the relationship between RE investments and portfolio performance. Applying econometric techniques on primary data collected from a sample of European investors, we study how the investors’ a-priori beliefs, their preferences over policy instruments and their attitude toward technological risk affect the likelihood of investing in RE projects. We also demonstrate that portfolio performance increases with an increase of the RE share in the portfolio. Implications for scholars, investors, technology managers and policy makers are derived and discussed.

South Africa has experienced declining marriage rates and the increasing practice of cohabitation without marriage. This study aims to improve the understanding of the relationship between marital status and HIV in South Africa, an HIV hyperendemic country, through an analysis of findings from the 2012 South African National HIV Prevalence, Incidence and Behaviour Survey. The nationally representative population-based cross-sectional survey collected data on HIV and socio-demographic and behavioural determinants in South Africa. This analysis considered respondents aged 16 years and older who consented to participate in the survey and provided dried blood spot specimens for HIV testing (N = 17,356). After controlling for age, race, having multiple sexual partners, condom use at last sex, urban/rural dwelling and level of household income, those who were married living with their spouse had significantly reduced odds of being HIV-positive compared to all other marital spouses groups. HIV incidence was 0.27% among respondents who were married living with their spouses; the highest HIV incidence was found in the cohabiting group (2.91%). Later marriage (after age 24) was associated with increased odds of HIV prevalence. Our analysis suggests an association between marital status and HIV prevalence and incidence in contemporary South Africa, where odds of being HIV-positive were found to be lower among married individuals who lived with their spouses compared to all other marital status groups. HIV prevention messages therefore need to be targeted to unmarried populations, especially cohabitating populations. As low socio-economic status, low social cohesion and the resulting destabilization of sexual relationships may explain the increased risk of HIV among unmarried populations, it is necessary to address structural issues including poverty that create an environment unfavourable to stable sexual relationships.

A method designed to label platelets with 111-In-oxine was investigated in volunteers with normal hematological findings and patients showing disturbed platelet turnover with particular account being taken of the following aspects: Suitability of the method to label blood taken up in special rubber bags in order to improve platelet recovery in the presence of thrombopenia and to ensure greater sterility; simplicity of blood sample processing to determine survival time; behaviour of the platelets in the organism of individuals with normal cell counts and value of determinations of platelet survival time and site of degradation in patients showing disturbed platelet turnover both from the diagnostic point of view and with regard to the possible therapeutic consequences to be drawn (splenectomy). The investigations revealed an average labeling rate of 24.9% for blood samples from healthy volunteers drawn up in rubber bags; the recovery rate was determined to be in the order of 43.2%. Our findings confirmed that an accurate diagnosis of thrombopenic disorders can be established on the basis of survival time curves plotted from the whole blood samples and also pointed to considerably longer survival times as compared to those determined for processed platelet concentrates. The time course of activity in liver and spleen was assessed by means of an Anger camera. The method of labeling blood collected in rubber bags was found to be particularly suitable for patients showing disturbed platelet turnover. Pathological degradation processes can be detected by functional measurements using special detectors. In cases where the organ activity curves obtained are difficult to interpret it may help to subtract the proportion of activity that is attributable to the circulating blood. (TRV)

Although the neighbourhoods and health field is well established, the relationships between neighbourhood selection, neighbourhood preference, work-related travel behaviours, and transport infrastructure have not been fully explored. It is likely that understanding these complex relationships more fully will inform urban policy development, and planning for neighbourhoods that support health behaviours. Accordingly, the objective of this study was to identify associations between these variab...

Full Text Available Abstract Background Stroke is a major cause of disability and family disruption and carries a high risk of recurrence. Lifestyle factors that increase the risk of recurrence include smoking, unhealthy diet, excessive alcohol consumption and physical inactivity. Guidelines recommend that secondary prevention interventions, which include the active provision of lifestyle information, should be initiated in hospital, and continued by community-based healthcare professionals (HCPs following discharge. However, stroke patients report receiving little/no lifestyle information. There is a limited evidence-base to guide the development and delivery of effective secondary prevention lifestyle interventions in the stroke field. This study, which was underpinned by the Theory of Planned Behaviour, sought to explore the beliefs and perceptions of patients and family members regarding the provision of lifestyle information following stroke. We also explored the influence of beliefs and attitudes on behaviour. We believe that an understanding of these issues is required to inform the content and delivery of effective secondary prevention lifestyle interventions. Methods We used purposive sampling to recruit participants through voluntary sector organizations (29 patients, including 7 with aphasia; 20 family members. Using focus group methods, data were collected in four regions of Scotland (8 group discussions and were analysed thematically. Results Although many participants initially reported receiving no lifestyle information, further exploration revealed that most had received written information. However, it was often provided when people were not receptive, there was no verbal reinforcement, and family members were rarely involved, even when the patient had aphasia. Participants believed that information and advice regarding healthy lifestyle behaviour was often confusing and contradictory and that this influenced their behavioural intentions. Family
Full Text Available Abstract Background Patterns of physical activity (PA, domestic activity and sedentary behaviours are changing rapidly in Asia. Little is known about their relationship with obesity in this context. This study investigates in detail the relationship between obesity, physical activity, domestic activity and sedentary behaviours in a Thai population. Methods 74,981 adult students aged 20-50 from all regions of Thailand attending the Sukhothai Thammathirat Open University in 2005-2006 completed a self-administered questionnaire, including providing appropriate self-reported data on height, weight and PA. We conducted cross-sectional analyses of the relationship between obesity, defined according to Asian criteria (Body Mass Index (BMI ≥25, and measures of physical activity and sedentary behaviours (exercise-related PA; leisure-related computer use and television watching ("screen-time"; housework and gardening; and sitting-time adjusted for age, sex, income and education and compared according to a range of personal characteristics. Results Overall, 15.6% of participants were obese, with a substantially greater prevalence in men (22.4% than women (9.9%. Inverse associations between being obese and total weekly sessions of exercise-related PA were observed in men, with a significantly weaker association seen in women (p(interaction Conclusions Domestic activities and sedentary behaviours are important in relation to obesity in Thailand, independent of exercise-related physical activity. In this setting, programs to prevent and treat obesity through increasing general physical activity need to consider overall energy expenditure and address a wide range of low-intensity high-volume activities in order to be effective.
Evaluation of Self-Ratings for Health Information Behaviour Skills Requires More Heterogeneous Sample, but Finds that Public Library Print Collections and Health Information Literacy of Librarians Needs Improvement
Full Text Available Objective – To understand public library users’ perceptions of ability to locate, evaluate, and use health information; to identify barriers experienced in finding and using health information; and to compare self-ratings of skills to an administered instrument. Design – Mixed methods. Setting – Main library and two branches of one public library system in Florida. Subjects – 20 adult library users purposively selected from 131 voluntary respondents to a previously conducted survey (Yi, 2014 based on age range, ethnicity, gender, and educational level. Of the 20, 13 were female; 11 White, 8 Black, 1 Native American; most had attained college or graduate school education levels (9 each, with 2 having graduated from high school. 15 respondents were aged 45 or older. Methods – Intensive interviews conducted between April and May 2011 used critical incident technique to inquire about a recalled health situation. Participants responded to questions about skill self-appraisal, health situation severity, information seeking and assessment behaviour, use of information, barriers, and outcome. Responses were compared to results of the short form of the Test of Functional Health Literacy in Adults (S-TOFHLA test, administered to participants. Main Results – On a scale of 100, participants’ S-TOFHLA scores measured at high levels of proficiency, with 90% rating 90 points or above. Self-ratings of ability to find health information related to recalled need were ”excellent” (12 participants or “good” (8 participants. Fourteen participants did not seek library assistance; 12 began their search on the Internet, 5 searched the library catalogue, and 3 reported going directly to the collection. Resource preferences were discussed, although no frequency descriptions were provided. 90% of participants self-rated their ability to evaluate the quality of health information as “good” or “excellent.” Participants selected authority

Short-term changes in quitting-related cognitions and behaviours after the implementation of plain packaging with larger health warnings: findings from a national cohort study with Australian adult smokers
Durkin, Sarah; Brennan, Emily; Coomber, Kerri; Zacher, Meghan; Scollo, Michelle; Wakefield, Melanie
Background Plain packaging (PP) with larger graphic health warnings (GHWs) was implemented in Australia in late 2012. This study examined effects of these packaging changes on short-term changes in quitting-related cognitions and behaviours. Methods We used a series of cohorts of Australian adult cigarette smokers originally sourced from a nationally representative cross-sectional tracking survey, followed up approximately 1 month after their baseline interview (n(weighted)=5441). Logistic regression analyses compared changes in seven quitting-related outcomes over this 1-month follow-up period for the cohorts surveyed before PP, over the period of transition to PP, and during the first year of PP, adjusting for baseline levels of the outcome and covariates. Results Compared to the referent group of smokers who completed their follow-up survey pre-PP, those who were followed-up in the early transition period showed significantly greater increases in rates of stopping themselves from smoking (OR=1.51, 95% CI (1.08 to 2.10)) and higher quit attempt rates (OR=1.43, 95% CI (1.00 to 2.03)), those followed-up in the late transition period showed greater increases in intentions to quit (OR=1.42, 95% CI (1.06 to 1.92)) and pack concealment (OR=1.55, 95% CI (1.05 to 2.31)), and those followed-up in the first year of PP showed higher levels of pack concealment (OR=1.65, 95% CI (1.01 to 2.72)), more premature stubbing out of cigarettes (OR=1.55, 95% CI (1.01 to 2.36)), and higher quit attempt rates (OR=1.52, 95% CI (1.01 to 2.30)). Conclusions These findings provide some of the strongest evidence to date that implementation of PP with larger GHWs was associated with increased rates of quitting cognitions, microindicators of concern and quit attempts among adult cigarette smokers.

The theory of planned behaviour (TPB; Ajzen, 1991) has been used extensively to predict social and health behaviours. However, a critical test of the TPB is whether interventions that increased scores on the theory's predictors would engender behaviour change. The present research deployed a novel technique in order to provide this test. Statistical simulations were conducted on data for 30 behaviours (N=211) that estimated the impact of interventions that generated maximum positive changes in attitudes, subjective norms and perceived behavioural control (PBC) on subsequent intentions and behaviour. Findings indicated that interventions that maximized TPB variables had a substantial impact on behavioural intentions. Although TPB maximization increased the proportion of the sample that performed respective behaviours by 28% compared with baseline, the behaviour of a substantial minority of the sample (26%) did not change. The research also identified several interactions among TPB variables in predicting simulated intention and behaviour scores and investigated the mediating role of intentions in predicting behaviour.

This study tested the utility of the Theory of Planned Behaviour (TPB) to predict mothers' decisions to ensure their child engages in sun-protective behaviours. Mothers (N = 162) of children aged four or five years completed standard TPB items (attitude, subjective norm, perceived behavioural control, intention) and additional variables of role construction, mothers' own sun safe behaviour, planning and past behaviour. One week later, participants (N = 116) reported their behaviour. Results found support for the TPB constructs, role construction, past behaviour and the mediating role of planning. These findings can inform strategies to prevent skin cancer. PMID:22253324

This paper reports on a study that the researchers call: 'Keeping found things found on the Web' or 'KFTF'. The research focuses on the classic problem of ensuring that once a useful information source or channel has been located, it can be found again when it is needed. To achieve this goal, individuals engage in information behaviour that the research team refers to as, keeping behaviour and re-finding behaviour. The research study observed both types of information behaviour. To study keep...

A major challenge in studying social behaviour stems from the need to disentangle the behaviour of each individual from the resulting collective. One way to overcome this problem is to construct a model of the behaviour of an individual, and observe whether combining many such individuals leads to the predicted outcome. This can be achieved by using robots. In this review we discuss the strengths and weaknesses of such an approach for studies of social behaviour. We find that robots-whether s...

Interest in individual differences in animal behavioural plasticities has surged in recent years, but research in this area has been hampered by semantic confusion as different investigators use the same terms (e.g. plasticity, flexibility, responsiveness) to refer to different phenomena. The first goal of this review is to suggest a framework for categorizing the many different types of behavioural plasticities, describe examples of each, and indicate why using reversibility as a criterion for categorizing behavioural plasticities is problematic. This framework is then used to address a number of timely questions about individual differences in behavioural plasticities. One set of questions concerns the experimental designs that can be used to study individual differences in various types of behavioural plasticities. Although within-individual designs are the default option for empirical studies of many types of behavioural plasticities, in some situations (e.g. when experience at an early age affects the behaviour expressed at subsequent ages), 'replicate individual' designs can provide useful insights into individual differences in behavioural plasticities. To date, researchers using within-individual and replicate individual designs have documented individual differences in all of the major categories of behavioural plasticities described herein. Another important question is whether and how different types of behavioural plasticities are related to one another. Currently there is empirical evidence that many behavioural plasticities [e.g. contextual plasticity, learning rates, IIV (intra-individual variability), endogenous plasticities, ontogenetic plasticities) can themselves vary as a function of experiences earlier in life, that is, many types of behavioural plasticity are themselves developmentally plastic. These findings support the assumption that differences among individuals in prior experiences may contribute to individual differences in behavioural

Full Text Available Abstract Background A thorough understanding of the contexts of sexual behaviour of the people who are vulnerable to HIV infection is an important component in the battle against AIDS epidemic. We conducted a qualitative study to investigate perceptions, attitudes and practices of sexually active people in three districts of northern Tanzania with the view of collecting data to inform the formulation of appropriate complementary interventions against HIV and AIDS in the study communities. Methods We conducted 96 semi-structured interviews and 48 focus group discussions with sexually active participants (18-60 years of age who were selected purposively in two fishing and one non-fishing communities. Results The study revealed a number of socio-economic and cultural factors which act as structural drivers of HIV epidemic. Mobility and migration were mentioned to be associated with the risk of HIV acquisition and transmission. Sexual promiscuous behaviour was common in all study communities. Chomolea, (a quick transactional sex was reported to exist in fishing communities, whereas extramarital sex in the bush was reported in non-fishing community which was predominantly Christian and polygamous. Traditional practices such as Kusomboka (death cleansing through unprotected sex was reported to exist. Other risky sexual behaviour and traditional practices together with their socio-economic and cultural contexts are presented in details and discussed. Knowledge of condom was low as some people mistook them for balloons to play with and as decorations for their living rooms. Acute scarcity of condoms in some remote areas such as vizingani (fishing islands push some people to make their own condoms locally known as kondomu za pepsi using polythene bags. Conclusions HIV prevention efforts can succeed by addressing sexual behaviour and its socio-economic and cultural contexts. More innovative, interdisciplinary and productive structural approaches to HIV

By revisiting Scitovsky's work on well-being, which introduces 'novelty' into the consumer's option set as a peculiar source of satisfaction, this paper finds a number of connections with the recent behavioural economics so as to open new lines on inquiry. First, similarly to behavioural economics, Scitovsky used psychology to interpret sub-optimal choices. However, his welfare benchmark is different from rational choice, as understood by the economists, because 'novelty' implies a very stron...

The impact of group norms on forming consumer behaviour is an important attribute of man’s social life. The market segmentation principles acknowledge the presence of this phenomenon. People belong to different age group, professional status, income levels, educational status etc. are seemed to display some specific consumer behaviour that can be attributed to a particular group. The present study attempts to find the influence of certain selected group norms on consumption pattern.

Full Text Available This study investigates the extent and the determinants of tunnelling behaviour in five ASEAN countries (i.e. Indonesia, Malaysia, Philippines, Singapore, and Thailand. Related party transactions (RPTs in the form of loans to related parties are used as the proxy for tunnelling. With 200 firm-year observations over the period 2006-2009, this study finds a positive association between managerial ownership and the extent of tunnelling.The other important findings are that business environment (BE, foreign ownership, and independent directors are ineffective governance mechanisms to rein in tunnelling behaviour. This suggests that regulators need to evolve more effective governance mechanisms.

Many animals exhibit behavioural syndromes—consistent individual differences in behaviour across two or more contexts or situations. Here, we present adaptive, state-dependent mathematical models for analysing issues about behavioural syndromes. We find that asset protection (where individuals with more ‘assets’ tend be more cautious) and starvation avoidance, two state-dependent mechanisms, can explain short-term behavioural consistency, but not long-term stable behavioural types (BTs). Thes...

Entry of new firms can be difficult or even impossible at capacity constrained facilities, despite the actual cost of entering is low. Using a game theoretic model of incumbent firms’ pricing behaviour under these conditions, it is found that under the assumption of Bertrand competition and firms having different costs, the optimal pricing behaviour imply price stickiness and upward pricing. The findings further suggest a competitive behaviour of incumbents of disposing weaker opponents only ...

The theory of planned behaviour assumes that the accuracy of perceived behavioural control (PBC) determines the strength of the PBC-behaviour relationship. However, this assumption has never been formally tested. The present research developed and validated a proxy measure of actual control (PMAC) in order to test the assumption. In two studies, participants completed measures of intention and PBC, and subsequently completed measures of behaviour and the PMAC. Validity of the PMAC was established by findings showing; (a). that the PMAC moderated the intention-behaviour relation, and (b). that PMAC scores did not reflect attributions for participants' failure to enact their stated intentions. Accuracy was operationalized as the difference between PBC and PMAC scores. Consistent with theoretical expectations, several analyses indicated that greater accuracy of PBC was associated with improved prediction of behaviour by PBC. PMID:14567844

Attitudes are typically treated as unidimensional predictors of both behavioural intentions and subsequent behaviour. On the basis of previous research showing that attitudes comprise two independent, positive and negative dimensions, we hypothesized that attitudes would be bi-dimensional predictors of both behavioural intentions and subsequent behaviour. We focused on health-risk behaviours. We therefore also hypothesized that the positive dimension of attitude (evaluations of positive behavioural outcomes) would better predict both behavioural intentions and subsequent behaviour than would the negative dimension, consistent with the positivity bias/offset principle. In Study 1 (cross sectional design), N = 109 university students completed questionnaire measures of their intentions to binge-drink and the positive and negative dimensions of attitude. Consistent with the hypotheses, both attitude dimensions independently predicted behavioural intentions and the positive dimension was a significantly better predictor than was the negative dimension. The same pattern of findings emerged in Study 2 (cross sectional design; N = 186 university students) when we predicted intentions to binge-drink, smoke and consume a high-fat diet. Similarly, in Study 3 (prospective design; N = 1,232 speed limit offenders), both the positive and negative dimensions of attitude predicted subsequent (6-month post-baseline) speeding behaviour on two different road types and the positive dimension was the better predictor. The implications for understanding the motivation of behaviour and the development of behaviour-change interventions are discussed. PMID:25440892

The paper reviews in summary form the generalised behaviour of soils under nonisothermal and chemically varying conditions. This generalised soil behaviour underlies the performance of a number of ground improvement techniques. The behaviour of frozen soil is examined first showing that some concepts of unsaturated soil mechanics appear to be readily applicable. Afterwards, the observation that volumetric behaviour of saturated and unsaturated soils at high temperature is similar, leads to th...
Full Text Available Purpose – to present the issue of dealing with negative word-of-mouth under the newly created conditions of social media and formulate a set of rules for dealing with negative contributions in social networks such as Facebook. Design/methodology/approach – The paper presents findings from both a quantitative survey of Czech Facebook users and expert interviews. Findings – The results of the survey that was done among internet users has proven, that Czech Facebook users are fully aware of the fact that by complaining publicly via social media they can get a company in a serious trouble and want to use it to their advantage. Expert interviews agreed on necessity of good knowledge of the community, quick response to the posts and careful consideration of deleting negative contributions. Research limitations/implications – the empirical research is focused on the Czech market that is specific in the field of internet user behaviour. Findings are primarily valid solely for the social network Facebook. Other platforms may differ in complaining behaviour of the users. Practical implications – research findings show, that social media play an important role in complaining behaviour of Czech internet users. This fact results in the necessity of the presence in social media and careful monitoring the word-of-mouth. Crucial factors of successful communication in social media are knowledge of the com munity, quick response to the posts and careful consideration of deleting negative contributions.Originality/Value – Word of mouth, nowadays the most powerful marketing tool and the strongest argument in the decision making process, is now not limited to the circle of nearest friends of family. Social media gives people a voice that is immediate and can have impact. Without an effective and fast reaction of the company, a serious harm can be suffered. The significance of social network Facebook in complaining behaviour of Czech consumers is assessed

Originally grounded in library and information science, the majority of information behaviour and information-seeking theories focus on task-based scenarios where users try to resolve information needs. While other theories exist, such as how people unexpectedly encounter information, for example......, they are typically related back to tasks, motivated by work or personal goals. This chapter, however, focuses on casual-leisure scenarios that are typically motivated by hedonistic needs rather than information needs, where people engage in searching behaviours for pleasure rather than to find...... information. This chapter describes two studies on (1) television information behaviour and (2) the casual information behaviours described by users of Twitter. The first study focuses on a specific casual-leisure domain that is familiar to many, while the second indicates that our findings generalise to many...
Full Text Available This article is a survey of behavioural analysis of criminal law. Behavioural analysis of criminal law exploits social science methodologies (behavioural economics, psychology and even sociology to explore the effects of criminal law norms and enforcement policy on criminals, judges, juries, lawyers and other decision-makers, to determine the optimal type and size of criminal sanctions, to identify the optimal design of the enforcement system and the rules of evidence. Unlike traditional economic analysis, the behavioural perspective is eclectic rather than unitary; it is composed of various psychological and sociological findings including cognitive biases and their effects, prospect theory, the effects of social norms, findings concerning the ways preferences and beliefs are being shaped and even studies concerning happiness. Behavioural theorists call for the understanding and at times exploitation of various cognitive misperceptions, biases and heuristics to increase the deterrent effect of criminal law prohibitions and sanctions and/or increase their effectiveness. This survey compares this approach to traditional retributive approach and to economic analysis of law. It also provides several examples in which behavioural insights were used and, last it evaluates the prospects that the behavioural approach will influence policy and legislation.
Translational and orientational excluded-volume fields encoded in particles with anisotropic shapes can lead to purely entropy-driven assembly of morphologies with specific order and symmetry. To elucidate this complex correlation, we carried out detailed Monte Carlo simulations of six convex space-filling polyhedrons, namely, truncated octahedrons, rhombic dodecahedrons, hexagonal prisms, cubes, gyrobifastigiums and triangular prisms. Simulations predict the formation of various new liquid-crystalline and plastic-crystalline phases at intermediate volume fractions. By correlating these findings with particle anisotropy and rotational symmetry, simple guidelines for predicting phase behaviour of polyhedral particles are proposed: high rotational symmetry is in general conducive to mesophase formation, with low anisotropy favouring plastic-solid behaviour and intermediate anisotropy (or high uniaxial anisotropy) favouring liquid-crystalline behaviour. It is also found that dynamical disorder is crucial in defining mesophase behaviour, and that the apparent kinetic barrier for the liquid-mesophase transition is much lower for liquid crystals (orientational order) than for plastic solids (translational order). © 2011 Macmillan Publishers Limited.

The main ideas, methods and results in the investigation of the asymptotic behaviour of exclusive processes are reviewed. We discuss power behaviour and its dependence on hadron quantum numbers, logarithmic corrections and properties of nonperturbative hadronic wave functions. Applications to meson and baryon form factors, strong, electromagnetic and weak decays of heavy mesons, elastic scattering, threshold behaviour of inclusive structure functions, etc., are described. Comparison of theoretical predictions with experimental data is made whenever possible. The review may be of interest to theoreticians, experimentalists and students specializing in elementary particle physics. The experts in this field can also find new results (nonleading logarithms, higher twist processes, novel applications, etc.). (orig.)

Climate change is likely the most critical societal challenge to the futures of today's children. Mitigation will require a concerted effort to change household energy behaviour electricity use, transportation and food consumption patterns. A first step to changing behaviour is to better understand current behaviour and its intrapersonal (knowledge and attitudes), interpersonal (norms, communication and behaviour) and contextual (demographics and geography) correlates. To date, our understanding of the energy behaviours of children is limited. To begin to fill this gap, we report the results of a survey on the electricity, transportation and food-related energy behaviours of 323 fourth- and fifth-grade girls and their parents in 31 Girl Scout troops in Northern California. Our findings show positive attitudes and perceived norms toward energy-saving behaviours among child and adult respondents, but low or moderate levels of knowledge, communication, and behaviour, particularly for behaviours that require adult assistance. Girls' choices about electricity behaviours appear to be governed by intrapersonal and interpersonal influences, while transportation behaviour is constrained by geographic context. Food-related behaviour, particularly meat consumption, was not readily modelled. Policy and education-related implications for future interventions aimed at enhancing children's energy-saving behaviours are discussed. (C) 2014 Elsevier Ltd. All rights reserved.

Knowing how individuals move between places is fundamental to advance our understanding of human mobility (González et al. 2008 Nature 453, 779-782. (doi:10.1038/nature06958)), improve our urban infrastructure (Prato 2009 J. Choice Model. 2, 65-100. (doi:10.1016/S1755-5345(13)70005-8)) and drive the development of transportation systems. Current route-choice models that are used in transportation planning are based on the widely accepted assumption that people follow the minimum cost path (Wardrop 1952 Proc. Inst. Civ. Eng. 1, 325-362. (doi:10.1680/ipeds.1952.11362)), despite little empirical support. Fine-grained location traces collected by smart devices give us today an unprecedented opportunity to learn how citizens organize their travel plans into a set of routes, and how similar behaviour patterns emerge among distinct individual choices. Here we study 92 419 anonymized GPS trajectories describing the movement of personal cars over an 18-month period. We group user trips by origin-destination and we find that most drivers use a small number of routes for their routine journeys, and tend to have a preferred route for frequent trips. In contrast to the cost minimization assumption, we also find that a significant fraction of drivers' routes are not optimal. We present a spatial probability distribution that bounds the route selection space within an ellipse, having the origin and the destination as focal points, characterized by high eccentricity independent of the scale. While individual routing choices are not captured by path optimization, their spatial bounds are similar, even for trips performed by distinct individuals and at various scales. These basic discoveries can inform realistic route-choice models that are not based on optimization, having an impact on several applications, such as infrastructure planning, routing recommendation systems and new mobility solutions.

A motivational model integrating self-determination theory, the theory of planned behaviour, and the health action process approach was tested in three samples in three behavioural contexts: fruit and vegetable, breakfast, and snack consumption. Perceived support for autonomous (self-determined) forms of motivation from parents and autonomous motivation from self-determination theory were hypothesised to predict intention and behaviour indirectly via the mediation of attitude and perceived behavioural control from the theory of planned behaviour. It was also expected that planning strategies would mediate the effect of intention on behaviour. Relations in the proposed models were expected to be similar across the behaviours. A two-wave prospective design was adopted. Three samples of high-school students (total N = 1041; 59.60% female; M age = 17.13 years ± 1.57) completed measures of perceived autonomy support, autonomous motivation, theory of planned behaviour constructs, planning strategies and behaviour for each of the three behavioural contexts. Three months later, 816 participants (62,24% female; M age: 17.13 years, SD = 1.58) of the initial sample self-reported their behaviour referred to the previous three months. Structural equation models provided support for the key hypothesised effects of the proposed model for the three health-related behaviours. Two direct effects were significantly different across the three behaviours: the effect of perceived autonomy support on perceived behavioural control and the effect of attitude on intention. In addition, planning strategies mediated the effect of intention on behaviour in fruit and vegetable sample only. Findings extend knowledge of the processes by which psychological antecedents from the theories affect energy-balance related behaviours. PMID:26423363

This is the FIRST of TWO linked articles on consumer behavioural analysis. Cognitive theories have dominated the field of consumer behaviour for the last few decades, however, an observed lack of consistency between attitudes and behaviour has suggested the need to investigate more thoroughly situational and behavioural variables. Consumer behaviour analysis can be viewed as an alternative theoretical approach that emphasizes situational variables and measures of behaviour. Within consumer be...

We formulate an in silico model of pathogen avoidance mechanism and investigate its impact on defensive behavioural measures (e.g., spontaneous social exclusions and distancing, crowd avoidance and voluntary vaccination adaptation). In particular, we use SIR(B)S (e.g., susceptible-infected-recovered with additional behavioural component) model to investigate the impact of homo-psychologicus aspects of epidemics. We focus on reactionary behavioural changes, which apply to both social distancing and voluntary vaccination participations. Our analyses reveal complex relationships between spontaneous and uncoordinated behavioural changes, the emergence of its contagion properties, and mitigation of infectious diseases. We find that the presence of effective behavioural changes can impede the persistence of disease. Furthermore, it was found that under perfect effective behavioural change, there are three regions in the response factor (e.g., imitation and/or reactionary) and behavioural scale factor (e.g., global/local) factors ρ-α behavioural space. Mainly, (1) disease is always endemic even in the presence of behavioural change, (2) behavioural-prevalence plasticity is observed and disease can sometimes be eradication, and (3) elimination of endemic disease under permanence of permanent behavioural change is achieved. These results suggest that preventive behavioural changes (e.g., non-pharmaceutical prophylactic measures, social distancing and exclusion, crowd avoidance) are influenced by individual differences in perception of risks and are a salient feature of epidemics. Additionally, these findings indicates that care needs to be taken when considering the effect of adaptive behavioural change in predicting the course of epidemics, and as well as the interpretation and development of the public health measures that account for spontaneous behavioural changes.

Full Text Available In order to limit the expansion of the HIV and AIDS epidemic in South Africa, it is important to develop targeted prevention strategies. The voluntary HIV counselling and testing (VCT programme appears to be effective for preventing the spread of the HI virus. This study adapted guidelines of the integrated model of behaviour prediction (IMBP into a questionnaire and examined the extent to which it predicts behaviour. A sample of 92 sports team members from Limpopo ranging from 14 to 30 years of age completed the questionnaire. Results suggested that beliefs about the outcomes of behaviour and beliefs about the expectations of others had a direct influence on the intention to undergo HIV counselling and testing. Efficacy beliefs, namely beliefs that there are factors that can facilitate behaviour, can lead to actual testing behaviour if accompanied by self-efficacy. Knowledge, intention and stigma are not related to VCT behaviour. Findings show that some constructs influence intention and test behaviour, but in ways not predicted by the model. Thus, the adequacy of the IMBP to determine HIV and AIDS-preventative behavioural intentions is questioned.

The present study examined the moderating role of attitudinal ambivalence within the theory of planned behaviour (TPB). Attitude, subjective norm, perceived behavioural control (PBC), behavioural intentions and self-reported behaviour were assessed in relation to 20 healthy eating behaviours in a prospective questionnaire design in 232 members of the general public in the UK. Between-participants univariate and multivariate analyses indicated attitude-behaviour and PBC-behaviour relationships to be weaker in higher ambivalence compared to lower ambivalence respondents. These effects were confirmed in within-participants analyses. The findings are discussed in terms of the role of ambivalence in furthering our understanding of relationships in the TPB. PMID:12713757

Suicidal behaviour is a serious public health issue. Suicidal behaviour includes completed suicide, suicide attempts, suicidal intent and/or plans and suicide ideation. Two prominent mechanisms, behavioural deficits, in particular poor problem-solving skills, and a certain cognitive style with overgeneralization, distortion and lack of positive expectations, have been identified in suicidal patients so far. Besides general therapy strategies, including the diagnostic process and a collaborative, confident relationship and strengthening of protective factors, specific behavioural strategies should aim at the modification of the behavioural repertoire and of cognitive strategies. The modification of the behavioural repertoire includes the direct modification of the behaviour, acquiring techniques for stress reduction and learning problem-solving strategies. Applied cognitive techniques comprise such as thought-stopping, examining options and alternatives, fantasizing consequences, externalizing inner voices, and reattribution. Psychotherapy with suicidal patients has a specific feature: It requires high activity of the therapist in terms of motivation and guidance of the patient. Regular assessment of the suicide risk at every session is a must. Nevertheless, the therapist should always be aware that it is impossible to prevent all suicidal acts. PMID:22926057

The purpose of this review is to describe the amount of time children spend in sedentary behaviour and to determine if there are specific factors that associate with sedentary behaviour in children. The following search terms were used to identify relevant articles: sedentary behaviour, inactivity, television, computer, video games, small screen, sitting, prevalence, patterns, correlates, factors and determinants. The databases used to conduct the search included PubMed, PsycINFO, ERIC (Education Resources Information Center) and Academic Search Premier. The studies reviewed were limited to those that sampled children (2-18 years), were written in English and used a measure of sedentary behaviour as the dependent variable. Several studies reported the time spent watching television or the proportion of children at or above a threshold for television viewing (eg, ≥3 h/day). Among the accelerometer studies included, the National Health and Nutrition Examination Survey is the largest and reported ∼6.1, 7.5 and 8.0 h/day mean sedentary time in children 6-11, 12-15 and 16-19 years old, respectively. Taken together, the existing literature across the world indicates a slightly higher level of sedentary behaviour in older children. Higher levels of sedentary behaviour were also reported in non-white children, children from lower socioeconomic status background and children from households with more access to televisions/computers. Lower levels of sedentary behaviour were reported in children whose parents have rules/limitations on screen time. PMID:21836174

The care of mentally ill people at home is being encouraged nowadays. As a result, the family members feel an increased burden of care and find it difficult to cope with the care of a schizophrenic patient at home. We interviewed the relatives of 62 schizophrenics systematically regarding the behaviour of the patients that was perceived to be distressful. This was done using the Scale for Assessment of Family Distress. It was noted that behaviours related to activity and self-care were perceived to be most distressful, and not aggressive or psychotic behaviour. Distress was more often reported by younger relatives and those with more education. The findings have implications in planning appropriate family intervention methods. PMID:1414410

In this paper it is argued that cognitive scientists, claiming the support of brain science and computer simulation, have revived a traditional view that behaviour is initiated by an internal, autonomous mind. In doing so, they have misused the metaphor of storage and retrieval, given neurology a misleading assignment, frequently replaced controlled experimental conditions with mere descriptions of conditions and the assessment of behaviour with statements of expectations and intentions, given feelings and states of mind the status of causes of behaviour rather than the products of the causes, and failed to define many key terms in dimensions acceptable to science.

Suicide is a complex public health problem of global importance. Suicidal behaviour differs between sexes, age groups, geographic regions, and sociopolitical settings, and variably associates with different risk factors, suggesting aetiological heterogeneity. Although there is no effective algorithm to predict suicide in clinical practice, improved recognition and understanding of clinical, psychological, sociological, and biological factors might help the detection of high-risk individuals and assist in treatment selection. Psychotherapeutic, pharmacological, or neuromodulatory treatments of mental disorders can often prevent suicidal behaviour; additionally, regular follow-up of people who attempt suicide by mental health services is key to prevent future suicidal behaviour.

In the beginning of the twentieth century, when Jacques Loeb's and John Watson's mechanistic view of life started to dominate animal physiology and behavioural biology, several scientists with different academic backgrounds got engaged in studying the wayfinding behaviour of ants. Largely unaffected by the scientific spirit of the time, they worked independently of each other in different countries: in Algeria, Tunisia, Spain, Switzerland and the United States of America. In the current literature on spatial cognition these early ant researchers-Victor Cornetz, Felix Santschi, Charles Turner and Rudolf Brun-are barely mentioned. Moreover, it is virtually unknown that the great neuroanatomist Santiago Ramón y Cajal had also worked on spatial orientation in ants. This general neglect is certainly due to the fact that nearly all these ant researchers were scientific loners, who did their idiosyncratic investigations outside the realm of comparative physiology, neurobiology and the behavioural sciences of the time, and published their results in French, German, and Spanish at rather inaccessible places. Even though one might argue that much of their work resulted in mainly anecdotal evidence, the conceptual approaches of these early ant researchers preempt much of the present-day discussions on spatial representation in animals.

We review the human literature examining the effects of neurological insult on human sexual behaviour. We provide a synthesis of the findings to date, and identify key brain regions associated with specific aspects of human sexual behaviour. These include subcortical and cortical regions, with the mesial temporal lobe and the amygdala in particular being a crucial structure in the mediation of human sexual drive.

Collective behaviour enhances environmental sensing and decision-making in groups of animals. Experimental and theoretical investigations of schooling fish, flocking birds and human crowds have demonstrated that simple interactions between individuals can explain emergent group dynamics. These findings indicate the existence of neural circuits that support distributed behaviours, but the molecular and cellular identities of relevant sensory pathways are unknown. Here we show that Drosophila melanogaster exhibits collective responses to an aversive odour: individual flies weakly avoid the stimulus, but groups show enhanced escape reactions. Using high-resolution behavioural tracking, computational simulations, genetic perturbations, neural silencing and optogenetic activation we demonstrate that this collective odour avoidance arises from cascades of appendage touch interactions between pairs of flies. Inter-fly touch sensing and collective behaviour require the activity of distal leg mechanosensory sensilla neurons and the mechanosensory channel NOMPC. Remarkably, through these inter-fly encounters, wild-type flies can elicit avoidance behaviour in mutant animals that cannot sense the odour--a basic form of communication. Our data highlight the unexpected importance of social context in the sensory responses of a solitary species and open the door to a neural-circuit-level understanding of collective behaviour in animal groups.

Economic arguments, such as saving money, are often used to promote pro-environmental actions -- for example, reducing energy use. However, research shows that people's environmental motives are sometimes better drivers of behavioural change.
It is argued in this paper that in the affluent, industrial societies, environmental behaviours like recycling are typically classified within ""the domain of morality"" in people's minds. Intentions regarding these types of behaviours are not ba a thorough - conscious or unconscious - calculation...... of the balance of costs and benefits. Rather, they are a function of the person's moral beliefs, i.e., beliefs in what is the right or wrong thing to do. The paper gives a brief review of the literature with the intention of uncovering problems and shortcomings in the framework of the SEU-model and...... the Theory of Reasoned Action (TRA) with regard to understanding recycling behaviour. Further, examples of misleading policy conclusions are discussed suggested that within the framework of cognitive psychology, Schwartz's model of altruistic behaviour offers a more satisfying starting point for...

Extreme soil water repellency can occur in nature via condensation of volatile organic compounds released during wildfires and can lead to increased erosion rate. Such extreme water repellent soil can be classified as superhydrophobic and shares similar chemical and topographical features to specifically designed superhydrophobic surfaces. Previous studies using high speed videography to investigate single droplet impact behaviour on artificial superhydrophobic have revealed three distinct modes of splash behaviour (rebound, pinned and fragmentation) which are dependent on the impact velocity of the droplet. In our studies, using high-speed videography, we show that such splash behaviour can be replicated on fixed 'model' water repellent soils (hydrophobic glass beads/particles). We show that the type of splash behaviour is dependent on both the size and chemical nature of the fixed particles. The particle shape also influences the splash behaviour as shown by drop impact experiments on fixed sand samples. We have also studied soil samples, as collected from the field, which shows that the type of droplet splash behaviour can lead to enhanced soil particle transport.

The purpose of this study was to test whether the construction workers have the tendency of engaging in risk compensation behaviours, and identify the demographic variables, which may influence the extent to which the construction workers may show risk compensation behaviours. Both quantitative (survey) and qualitative (interviews) approaches were used in this study. A questionnaire survey was conducted with all the construction workers on three building construction sites of a leading construction company in Australia. Semi-structured interviews were then conducted to validate the findings of the quantitative research. The findings indicate that workers tend to show risk compensation behaviours in the construction environment. The workers with more working experience, higher education, or having never been injured at work before have a higher tendency to show risk compensation in their activities than the others. The implication is that contractors need to assess the potential influence of workers' risk compensation behaviours when evaluating the effect of risk control measures. It is recommended that supervisors pay more attention to the behavioural changes of those workers who have more experience, higher education, and have never been injured before after the implementation of new safety control measures on construction site.

The paper provides an empirical analysis of price setting behaviour in Slovakia, using large micro-level dataset covering about 57% of Slovak CPI for the period 1997-2001. The novelty of the paper is the analysis of a country characterized by nearly double-digit inflation and undergoing massive changes in market structure during the process of transition and accession to the EU. Several empirical findings stand out. Similarly to results on advanced market economies, we find that price changes...

Mice housed in standard cages show impaired brain development, abnormal repetitive behaviours (stereotypies) and an anxious behavioural profile, all of which can be lessened by making the cage environment more stimulating. But concerns have been raised that enriched housing might disrupt standardization and so affect the precision and reproducibility of behavioural-test results (for example, see ref. 4). Here we show that environmental enrichment increases neither individual variability in behavioural tests nor the risk of obtaining conflicting data in replicate studies. Our findings indicate that the housing conditions of laboratory mice can be markedly improved without affecting the standardization of results. PMID:15602544
It is known from psychology that behaviour can be changed more quickly and long lasting by rewarding desirable behaviour than by penalizing undesirable behaviour. Rewarding road safety behaviour can also be effective, as shown by research into, for instance, the use of seatbelts and driving speeds.

This report discusses gender differences in the data collected in the OECD household survey on environmental behaviour. The survey asked a sample of 10 000 respondents from 10 countries (Norway, Sweden, Canada, France, Italy, the Netherlands, the Czech Republic, Mexico, Australia and Korea) concerning household behaviour with respect to five areas: recycling, energy and water saving, organic food consumption and transportation. This report identifies and describes gender differences in behaviour, in underlying preferences and in household characteristics in this data. We use regression analyses to identify and test for significant gender differences in preferences, and we use differences in means to test for gender differences in background variables and the total effect of gender on behaviour. In our estimations, where we test for significant gender differences in preferences, we find many significant differences with respect to several of the explanatory variables affecting behaviour. However, there was no clear pattern for most of these gender differences. The only systematic gender difference we found in the estimations was that the belief that they can actually contribute to a better environment seems to be a more important motivator for environmental friendly behaviour for men than it is for women. There are also many significant differences between the genders in the distribution of key background variables, in particular with respect to income, car ownership, participation in the workforce, education and choice of residence. However, these gender differences in preferences and background variables only result in pronounced gender differences in behaviour to a small degree. The exception is transportation, where gender differences are large and significant. Men have a higher probability of owning a car or a motorcycle than women. And given that the respondent owns a car, men drive significantly more than women. For the rest of the behaviour measured in this

BACKGROUND: Despite the important role positive reinforcement of pain behaviour is believed to play in chronic pain, there is a paucity of research regarding factors that influence the provision of such reinforcement. Attachment theory suggests that individuals high in attachment avoidance view the pain behaviour of others in a negative manner and would, therefore, provide little reinforcement of pain behaviour. As an initial step in evaluating this model, relationships between attachment dimensions and attitudes toward pain behaviour were examined. Attachment avoidance was hypothesized to be negatively associated with accepting attitudes toward pain behaviour. METHODS: A sample of undergraduate students (n=160) completed the Relationships Structures Questionnaire, which provides global ratings of adult attachment dimensions (anxiety and avoidance) by assessing attachment across four relationship targets (friend, mother, father and romantic partner). Attitudes regarding the acceptability of pain behaviour were assessed using male and female versions of the Appropriate Pain Behaviour Questionnaire (APBQ). RESULTS: Consistent with the hypothesis, attachment avoidance was negatively correlated with both APBQ-Female and APBQ-Male scores. Multiple regression analyses were used to investigate the relationships between the attachment scales and the APBQ scales while statistically adjusting for sex and testing for interaction effects. The findings revealed complex relationships involving interaction effects that provided further support for the hypothesis. CONCLUSIONS: The findings provided support for the hypothesis that attachment avoidance is associated with less accepting attitudes toward pain behaviour. Additional research regarding the role of attachment and attitudes on responses to pain behaviour is warranted. PMID:21165372
Full Text Available The article presents an overview of the research area of information behaviour. Information behaviour is defined as the behaviour of individuals in relation to information sources and channels, which results as a consequence of their information need, and encompasses passive and active searching of information, and its use. Theoretical foundations are presented, as well as some fundamental conceptual models of information behaviour and related concepts: information searching behaviour, which occurrs in active, purposeful searching for information, regardless of the information source used; and information seeking behaviour, which represents a micro-level of information searching behaviour, and is expressed by those individuals who interact with information retrieval systems.

Guilt is a moral emotion that is often looked upon as a negative trait. However, studies show that some individuals are more predisposed to think, feel and act in a more ethical manner because of a lower threshold to experience guilt. Some theories of helping behaviour emphasize the evolutionary mechanisms, while other theories stress the importance of social variables. This study investigated whether guilt proneness as a dispositional trait can be associated with prosocial behaviour. Five hundred sixty-nine participants reported in an online survey their own levels of guilt proneness, frequency of prosocial behaviour, and related cognitions such as empathy. This study is among the first to demonstrate how guilt proneness combined with empathy can explain additional variance in prosocial behaviour. The findings also indicate gender differences in the precursors of prosocial behaviour, suggesting women are more influenced by the effects of guilt proneness on prosocial behaviour than men.

Full Text Available This paper reviews current findings in the human aggression and antisocial behaviour literature and those in the animal abuse literature with the aim of highlighting the overlap in conceptualisation. The major aim of this review is to highlight that the co-occurrence between animal abuse behaviours and aggression and violence toward humans can be logically understood through examination of the research evidence for antisocial and aggressive behaviour. From examination through this framework, it is not at all surprising that the two co-occur. Indeed, it would be surprising if they did not. Animal abuse is one expression of antisocial behaviour. What is also known from the extensive antisocial behaviour literature is that antisocial behaviours co-occur such that the presence of one form of antisocial behaviour is highly predictive of the presence of other antisocial behaviours. From such a framework, it becomes evident that animal abuse should be considered an important indicator of antisocial behaviour and violence as are other aggressive and antisocial behaviours. The implications of such a stance are that law enforcement, health and other professionals should not minimize the presence of animal abuse in their law enforcement, prevention, and treatment decisions.

Full Text Available Abstract Background Implementation research is the scientific study of methods to promote the systematic uptake of clinical research findings into routine clinical practice. Several interventions have been shown to be effective in changing health care professionals' behaviour, but heterogeneity within interventions, targeted behaviours, and study settings make generalisation difficult. Therefore, it is necessary to identify the 'active ingredients' in professional behaviour change strategies. Theories of human behaviour that feature an individual's "intention" to do something as the most immediate predictor of their behaviour have proved to be useful in non-clinical populations. As clinical practice is a form of human behaviour such theories may offer a basis for developing a scientific rationale for the choice of intervention to use in the implementation of new practice. The aim of this review was to explore the relationship between intention and behaviour in clinicians and how this compares to the intention-behaviour relationship in studies of non-clinicians. Methods We searched: PsycINFO, MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, Science/Social science citation index, Current contents (social & behavioural med/clinical med, ISI conference proceedings, and Index to Theses. The reference lists of all included papers were checked manually. Studies were eligible for inclusion if they had: examined a clinical behaviour within a clinical context, included measures of both intention and behaviour, measured behaviour after intention, and explored this relationship quantitatively. All titles and abstracts retrieved by electronic searching were screened independently by two reviewers, with disagreements resolved by discussion. Discussion Ten studies were found that examined the relationship between intention and clinical behaviours in 1623 health professionals. The proportion of variance in behaviour explained by
Full Text Available Orientation: Employees’ perceptions of their leaders’ behaviour play a role in creating empowering environments where employees are willing to do more than what is expected, with retention of employees as a result.Research purpose: The aim of this study was to theoretically conceptualise and empirically determine the relationships between employees’ perception of their leaders’ empowering behaviour, psychological empowerment, organisational citizenship behaviours and intention to leave within a manufacturing division of an organisation.Motivation for the study: In the ever-changing work environment, organisations must capitalise on their human capital in order to maintain competitiveness. It is therefore important to identify the role of employees’ perception of leadership in contributing to the establishment of an environment where employees feel empowered, are willing to do more than what is expected and want to stay in the organisation.Research design, approach and method: A non-experimental, cross-sectional survey design was used. The total population (N = 300 employed at the manufacturing division was targeted. Two hundred completed questionnaires were obtained. The Leader Empowering Behaviour Questionnaire, Measuring Empowerment Questionnaire, Organisational Citizenship Behaviour Questionnaire and Intention to Leave Scale were administered.Main findings: Employees’ perception of their leaders’ empowering behaviour (keeping employees accountable, self-directed decision-making and people development, psychological empowerment (attitude and influence and organisational citizenship behaviours (loyalty, deviant behaviour and participation predict intention to leave the organisation.Practical/managerial implications: Organisations should foster the elements of a positive organisation, in this case leader empowering behaviours, if they want to retain their employees.Contribution/value-add: The results of this research contribute to

Objectives To understand parents’ perspectives of their preschoolers’ physical activity behaviours. Methods A maximum variation sample of 71 parents explored their preschoolers’ physical activity behaviours through 10 semi-structured focus group discussions. Results Parents perceived Canada’s Physical Activity Guidelines for Children as inadequate; that their preschoolers get and need more than 30–90 minutes of activity daily; and that physical activity habits must be established during the preschool years. Nine barriers against and facilitators toward adequate physical activity were proposed: child’s age, weather, daycare, siblings, finances, time, society and safety, parents’ impact, and child’s activity preferences. Discussion The need for education and interventions that address current barriers are essential for establishing physical activity as a lifestyle behaviour during early childhood and, consequently, helping to prevent both childhood and adulthood obesity.

Full Text Available Employee misconduct in the workplace is relatively common and may be counterproductivein social and material terms. To identify which undesirable behavioursare considered acceptable is the first step to develop ways to reducedeviance in organizational settings. The purpose of this study was to examinethe perceived acceptability of deviant behaviour in the workplace, and to analysethe relation between the degree of such acceptance with organizationalcommitment, job satisfaction, and organizational tenure. Data was obtainedfrom 223 adults employed full-time. Results suggest a positive relationshipbetween the degree of acceptability of certain forms of deviant behaviour andorganizational commitment, but not with job satisfaction. They further indicatethat tenure was the factor having the most impact on the acceptanceof deviant behaviours. Implications of the findings for the management arediscussed.

That is why the taxpayer behaviour has grown as a subject of research, in many fields b...
Occupational injuries, accidents, trips of equipment, emergencies, and idle times represent a loss from each megawatt hour which we could have supplied to the network, or other costs related to settlement or compensation for damages. All of it can be caused by short lack of attention while doing a routine job, ignoring safety indicators, and rules. Such behaviour would not be a characteristic of a professional. People working at the nuclear power plants are the first ones to learn about the Values and Behaviour Model. (author)

Full Text Available Young people learn more about sexual and reproductive health from uninformed sources and in our Indian culture, talking about sex and related issues are considered as taboo. Consequently, little information is provided to adolescents and youth about sexual health which resulted in risky sexual behaviour. In India, one-half of all young women are observed to be sexually active by the time they are 18 years. With the advent of mass media, internet, mobile phone and electronic communication gadgets; the health/ sex behaviour of youth undergo enormous changes. With this back drop, this study was carried out to assess the perceived sexual norms, perceived self behaviour of youth on birth control & protected sex, and perceived sexual involvement of peer youth. The findings revealed that though majority of the youth uphold the value system and have higher level of sexual norms in terms of perceived knowledge on general youth; the self perceived behaviour showed a negative and dangerous trend as most of them would not adopt birth control and protected sex measures; if happened to have premarital sex. Similarly the overall youth perception on sexual involvement of peer members in the villages observed that considerable percent of both boys and girls have sexual relationship which attracted the need for sexual health education and warrants an integrated comprehensive package of behaviour modification for the rural youth.
Full Text Available The aim of this study is to make an analysis of the citation networks between the Spanish Social Science journals using the citations index IN-RECS. Different maps were generated representing the overall structure of Social Sciences and a specific analysis of Library and Information Science was conducted. The indicator betweeness was used as a measure of interdisciplinarity. The results reveal the existence of two main clusters, one formed by the Psychology and the Education and other with a prominent location of the Economics and the Political Science; Sociology is the main connexion between the two clusters. The journals with the highest rate of betweeness were Revista de Educación and Papeles de Economía. The Library and Information Science appears in a marginal side of the different maps. Revista Española de Documentación Científica is the most relevant journal with the largest betweeness rate due to its significant relationships with international journals. The results show that IN-RECS is a useful tool for the structural study of the Spanish Social Sciences.

Temporal stability of behavioural intentions and perceived behavioural control (PBC) within the Theory of Planned Behaviour were examined as moderators of the cognition-behaviour relationships in two studies. Study 1 (N = 201) examined attendance at health screening appointment (infrequently performed behaviour) using an objective measure of attendance. The impact of intentions and past behaviour on behaviour was moderated by intention stability. In addition, stable intentions were more strongly related to attitudes and past behaviour. Study 2 (N = 407) examined eating a low-fat diet (frequently performed behaviour) using a self-report measure of behaviour. The impact of intentions on behaviour was moderated by intention stability, while the impact of PBC and past behaviour on behaviour was moderated by PBC stability. Stable intentions were more strongly related to attitudes, subjective norms and PBC. Stable PBC was more strongly related to attitudes and past behaviour. The discussion considers the implications of the findings for furthering the understanding of the proximal determinants of behaviour and emphasizes the importance of temporal stability as a key measure of the strength of intentions and PBC.

Representations of cellular processes that can be used to compute their future behaviour would be of general scientific and practical value. But past attempts to construct such representations have been disappointing. This is now changing. Increases in biological understanding combined with advances in computational methods and in computer power make it possible to foresee construction of useful and predictive simulations of cellular processes.

The purpose of this article is to provide a survey of the diversity of primate locomotor behaviour for people who are involved in research using laboratory primates. The main locomotor modes displayed by primates are introduced with reference to some general morphological adaptations. The relationships between locomotor behaviour and body size, habitat structure and behavioural context will be illustrated because these factors are important determinants of the evolutionary diversity of primate locomotor activities. They also induce the high individual plasticity of the locomotor behaviour for which primates are well known. The article also provides a short overview of the preferred locomotor activities in the various primate families. A more detailed description of locomotor preferences for some of the most common laboratory primates is included which also contains information about substrate preferences and daily locomotor activities which might useful for laboratory practice. Finally, practical implications for primate husbandry and cage design are provided emphasizing the positive impact of physical activity on health and psychological well-being of primates in captivity.
Full Text Available The behavior of pigs can be divided into several categories, which include maternal behavior, aggressive behavior, sexual behavior, feeding behavior, and various other forms of emotional behavior. Domestication has caused many changes in the original behaviour of boar, such as in reproductive and sexual behaviour, and has lead to a general increase in social tolerance between animals. Further modifications in behaviour are also possible, as suggested by the optimization of environmental factors which affect maternal behavior. The behaviour of a sow after farrowing appeared as a consequence of natural selection for protection of piglets from predators in the wild boar population, and affects the survival of piglets and the longevity of the sow in breeding. The behavior of the sows which includes the protection of the piglets from predators appears as a consequence of natural selection in the wild boar population. Familiarity with the molecular mechanisms which determine the patterns of behavior enables understanding of behavioral problems such as aggressiveness and helps the improvement of the well-being of pigs. Research conducted on pigs has determined that there are regions on chromosomes 2, 6, 10, 14, and 15, and chromosome X which can explain the genetic aspect of appearance of some behavioral patterns in sows. The goal of this paper is to illustrate the behavioral patterns appeared in the populations of domestic breeds of pigs and their genetic aspects, which knowledge may provide some help in improving the production qualities and creating higher economic gain during production.
Conclusions: Few studies tested predictability of the TPB in populations with or at-risk of diabetes. This review highlighted differences in the predictive utility of the TPB suggesting that the model is behaviour and population specific. Findings on key determinants of specific behaviours contribute to a better understanding of mechanisms of behaviour change and are useful in designing targeted behavioural interventions for different diabetes populations.

Full Text Available Reindeer (Rangifer tarandus kept in corrals or otherwise forced to clump typically start milling in response to stressing events. This behaviour is generally considered to have an antipredator effect. An inquiry on herd behaviour, to which 35 Norwegian reindeer husbandry districts responded, showed that 32 experienced that corralled rein¬deer consistently circled leftwards, whereas the remaining three reported consistently rightward circling. Regular monitoring of a reindeer herd in central Norway over a two-year period (1993-94, and experimental studies on a fraction of the same herd, revealed the following traits. Free-ranging reindeer showed no right- or left-turning preference during grazing or browsing, but when the reindeer were driven into corrals or forced to clump in the open they invariably rotated leftwards. The circling of corralled reindeer was triggered at an average group size of 20 to 25 animals, apparently independently of the age and sex of the animals. When they dug craters in the snow to reach food, the reindeer used their left foreleg significantly more often than their right. In 23 out of 35 reindeer, the right hemisphere of the brain was heavier than the left. However, in the sample as a whole, the weights of the left and right hemispheres did not differ significantly. Lateralised behaviour in reindeer is thought to be determined by natural and stress induced asymmetries in brain structure and hormonal activity. In addition, learning is probably important for passing on the behaviour between herd members and generations. Differences in lateralised behaviour between nearby herds are thought to be related primarily to different exposure to stress and learning, whereas genetical and environmental fac¬tors (e.g. diet, age structure and sex ratio are probably more important for explaining differences between distant pop¬ulations.
Full Text Available In humans and other mammals, drugs of abuse alter the function of biogenic amine pathways in the brain leading to the subjective experience of reward and euphoria. Biogenic amine pathways are involved in reward processing across diverse animal phyla, however whether cocaine acts on these neurochemical pathways to cause similar rewarding behavioural effects in animal phyla other than mammals is unclear. Previously, it has been shown that bees are more likely to dance (a signal of perceived reward when returning from a sucrose feeder after cocaine treatment. Here we examined more broadly whether cocaine altered reward-related behaviour, and biogenic amine modulated behavioural responses in bees. Bees developed a preference for locations at which they received cocaine, and when foraging at low quality sucrose feeders increase their foraging rate in response to cocaine treatment. Cocaine also increased reflexive proboscis extension to sucrose, and sting extension to electric shock. Both of these simple reflexes are modulated by biogenic amines. This shows that systemic cocaine treatment alters behavioural responses that are modulated by biogenic amines in insects. Since insect reward responses involve both octopamine and dopamine signalling, we conclude that cocaine treatment altered diverse reward-related aspects of behaviour in bees. We discuss the implications of these results for understanding the ecology of cocaine as a plant defence compound. Our findings further validate the honey bee as a model system for understanding the behavioural impacts of cocaine, and potentially other drugs of abuse.

The historical background of the development of behaviour therapy is described. It was based on the prevailing behaviourist psychology and constituted a fundamentally different approach to the causes and treatment of psychological disorders. It had a cold reception and the idea of treating the behaviour of neurotic and other patients was regarded as absurd. The opposition of the medical profession and psychoanalysts is explained. Parallel but different forms of behaviour therapy developed in the US and UK. The infusion of cognitive concepts and procedures generated a merger of behaviour therapy and cognitive therapy, cognitive behaviour therapy (CBT). The strengths and limitations of the early and current approaches are evaluated. PMID:25462876
Communication is probably one of the major means of life maintenance. Communication involves the use of signals, which can be visual, audial, olfactory etc. Organisms communicate in many different contexts, ranging from establishing own identity, foraging for food, finding a mate, protecting their territory, to more sophisticated ones such as engaging in social behaviour. Recognition is the action or process of recognizing or being recognized. Recognition based on olfactory cues is perhaps be...

Full Text Available This study examines the relationship between organizational citizenship behaviour, hospital corporate image and performance. Questionnaires were distributed to 350 patients and 298 usable questionnaires were returned representing a return rate of 85.7%. The study employs a Structural Equation Model to test four hypotheses on organizational citizenship behaviours, hospital corporate image and performance. The findings reveal that hospitals can increase performance through organizational citizenship behaviour and positive corporate image. However, it was also discovered that there is a negative covariance between organizational citizenship behaviour and hospital corporate image despite their individual positive contribution to performance. Therefore, hospital management should develop an organizational climate (such as recognition, additional reward, promotion, etc. that can promote organizational citizenship behaviour and enhance a positive corporate image while preventing situations that will discourage staff from rendering extra positive discretionary work related services.

The main thesis of these essays is that social phenomena are different from psychological phenomena and thus social sciences do not belong to behavioural sciences. Chapter 1 introduces the fundamental problem of the rational choice theory ("Macaulay's problem"): either the theory is empirical and false or it is without empirical content and true. Various suggested solutions to this problem are reviewed and criticized. It is argued that the problem is evaded once it is admitted that rational c...

Internet is a useful tool for everybody in a technologically advanced world. As Internet appears and develops, it creates a totally new network environment. The development of commerce on the Internet based on virtual communities has become one of the most successful business models in the world. After analyzing the concept of internet, the e-commerce market and its marketing mix and the benefits and limitations of the Internet, we have presented a few studies on Internet user behaviour. Furt...
Traditional economic theory assumes that individuals are self-interested. They only care about their own well-being and disregard the impact of their actions on the others. However, the assumption of selfish individuals is unable to explain a number of important phenomena and puzzles. Individuals frequently engage in actions that are costly to themselves with noapparent reward. Behavioural economics provides plausible explanations for these actions.Individuals can be “boundedly rational" (Sim...

The aim of this research was to determine the adsorption behaviour of bulgur. Three different particle sizes (2dry matter and 4.96-16.57, respectively. Constant k was between 0.85 and 0.93, and GAB equation was determined to fit very well for bulgur adsorption, because of %E values lower than 10%. Bulgur must be stored below 70% relative humidity and with less than 10 g water per 100 g of dry mater. PMID:26575716
Short duration or weak expression of oestrus are frequently cited as major reasons for poor results when artificial insemination of Bos indicus breeds is attempted. The existing literature on sexual behaviour certainly indicates that oestrus sometimes lasts for only a few hours in Bos indicus, but similar patterns are also reported in Bos taurus animals. The period of sexual receptivity in suckled Hereford or Hereford-dairy cross-breds maintained in small, totally confined groups ranged from 1 to 18 h, with a mean of 4.4 h and a median of 3.5 h. In totally confined Holstein cows the onset of the LH surge always followed the beginning of homosexual activity by 1 or 2 h even when the period of receptivity was very short. Thus, the beginning rather than the end of oestrus should be used for estimating ovulation time. The expression of sexual behaviour is modified by many factors, including environmental conditions, the number of peri-oestrous females in the group and the presence of observers. In Hereford beef, Holstein dairy and probably all other cattle breeds, the variability in duration and intensity of oestrous activity is very large, so generalizations on a typical individual behavioural pattern are not possible.

This paper’s aim is to provide an in-depth elucidation of the many aspects that influence consumer behaviour. The study of consumer behaviour emphasizes the “why” and “how” questions involved in decision making and buying behaviour. This exciting field visits a dynamic blend of themes of consumer marketing strategies, psychology and behavioural discipline. Consumer behaviour in this day and age is highly applicable to modern society as it is an integral part of our everyday lives. This paper ...
Using different measures of self-reported and other-reported environmental behaviour (EB), two important theoretical models explaining EB--Hines, Hungerford and Tomera's model of responsible environmental behaviour (REB) and Ajzen's theory of planned behaviour (TPB)--were compared regarding the fit between model and data, predictive ability,…

We tested a model of the associations between students' perceptions of their physical education teacher's controlling behaviour, perceptions of basic psychological need thwarting, anger and bullying behaviour. School students (N = 602; M age = 12.88, SD = 1.37) from 10 schools completed measures of perceived teachers' controlling behaviour and perceived thwarting of the psychological needs for autonomy, competence, and relatedness in physical education context and self-reported bullying and anger. A well-fitting structural equation model demonstrated that students' perceptions of the negative conditional regard and intimidation exhibited by the teacher had significant indirect effect on students' feelings of anger and bullying behaviour through the perceived psychological need thwarting in physical education. Findings suggest that physical education teachers who avoid the use of negative conditional regard and intimidation in their classes have students who perceive less need thwarting and report less bullying behaviour.

Full Text Available This paper discusses sexual behaviour findings collected through eleven homogenous focus group discussions conducted among women and men in a predominantly Zulu population in rural KwaZulu-Natal, South Africa. The objective of this paper is to shed light on sexual behaviour in a rural community. The findings suggest that sex is a taboo subject and the discussion around it is concealed in the use of polite language, euphemisms, and gestures. There are gender and generational dimensions to the discussion of sex. The contribution of this paper lies in the identification of what rural people discuss about sex and the influence of cultural practices and urban or global forces on sexual behaviour in rural areas. The paper adds to the growing body of literature on the use of focus groups in understanding sexual behaviour in rural contexts.
The success of conventional fiber reinforced composites (FRC) relies on the quality of bonding between fibers and matrix. A review of literatures shows that there is a lack of theoretical models and experimental findings on the interfacial behaviours of the SMA-composites. In the past, the operation limit as well as the ideal actuation condition of SMA inclusions could not be predicted accurately during the design stage and the SMA-composite structures may therefore suffer a potential risk of sudden failure due to overloading or over-actuation. The theoretical models developed in this research provide a study basis for the prediction of internal stresses and interfacial strength of the SMA-composites. Martensite volume fraction is considered as a critical parameter which determines the material properties and shape memory effect (SME) of the SMA inclusions. The proposed model reproduce the SMA behaviour inside a substrate, evolutions of martensite volume fraction and elastic modulus of SMA, and the internal stresses along the embedded length in different loading and actuation scenarios. The concepts of 'constant martensite volume fraction region (CMR)' and 'constant axial stress region (CASR)' are proposed to justify the desired SMA actuation. In addition, substantial improvement of the initial debond stress is predicted with the increase of the actuation temperature. The 'Optimum Actuation Condition (OAC)' that ensures the reinforcement of SMA composite but avoids the failure of composite interface due to over-actuation is also defined to optimize the application of SME in the composite structure within a safety actuation limit. A simplified OAC (SOAC) is also developed to provide an analytical solution of OAC and thus the ideal actuation temperature for achieving such specific actuation condition can be estimated more easily. Single fiber pullout test and finite element analysis (FEA) are employed to evaluate the interfacial behaviours and analyze the stress

This paper aims to understand the behaviour of texting and driving among the broader driving public in Australia and uncover whether attitudes are congruent with behaviours. Recent studies have generally been focussing on the behaviours of 18-24 year olds suggesting that the practice is mainly...... confined to people in this age bracket. Findings from an anonymous online survey show that the practice of texting and driving is widespread in Australia and not just confined to the younger demographic. Additionally, evidence suggests smart phone users are more likely to engage in texting while driving...

@@ Base on the database of families of structurally similar proteins, a statistical study is made on the scaling behaviour of occupying probabilities of conserved sites (Pc) in various protein families. A power-law decrease of Pc with the increasing protein-chain length Lf is found. This is related to the power-law scaling behaviour of the occurring probabilities of local contact interactions (Plocal) between residues. In addition, applying residue grouping, we find the same scaling behaviour when the number of residue types is more than 12, indicating that 12 residue types are enough to present the complexity of proteins.

In this paper, a novel software system for animal behaviour tracking is described. It is used for tracking fish filmed in aquariums using a low quality acquisition system. The tracking is based on a multiscale template matching technique that finds both the position and the orientation...... of the tracked fish. The template is matched in the background subtracted frames, where the background is estimated using a median based approach. The system is very stable and has been used in a large behavioural study design to the use of the behavioural pattern known as mate choice copying in Betta splendens....
The thesis explores the insights from behavioural economic research for tax compliance. The theoretical model of tax evasion by Allingham and Sandmo (1972) is reviewed and then enriched with findings from research on bounded rationality and unbounded motivation for human behaviour. In specific implications for tax compliance of loss aversion, overweighting of low probabilities, small sample bias and procrastination are discussed. It is suggested that the perception of probab...

We explore the influences on the saving behaviour of children aged 11 to 15 using panel data drawn from the British Household Panel Survey Youth Questionnaire. Our empirical findings suggest that parental allowances/pocket money exert a moderating influence on the probability that a child will save, whilst hours of paid work undertaken by the child are positively associated with the probability that a child will save. The saving behaviour of parents, however, does not appear to influence the ...

Using data from the British Household Panel Survey and Understanding Society, we examine the saving behaviour of individuals over time. Initially, we explore the determinants of the saving behaviour of children aged 11–15. Our findings suggest that parental allowances/pocket money (earnings from part-time work) lower (increase) the probability that a child saves. There is also evidence that the financial expectations of the head of household have an influence on their offspring’s saving behav...

This paper studies the relationship between schooling and political behaviour in ethnically divided societies. It draws on survey data from Catalonia to investigate how the introduction in 1983 of a bilingual education system affects political behaviour. Using within and between cohort variation in exposure to Catalan language at school, we find that individuals who have experienced greater exposure to teaching in Catalan are more likely to declare to have voted in 1999 regional elections and...

We investigate a set of complex heart rate time series from healthy human in different behaviour states with the detrended fluctuation analysis and diffusion entropy (DE) method. It is proposed that the scaling properties are influenced by behaviour states. The memory detected by DE exhibits an approximately same pattern after a detrending procedure. Both of them demonstrate the long-range strong correlations in heart rate. These findings may be helpful to understand the underlying dynamical ...

Animals locate and track chemoattractive gradients in the environment to find food. With its small nervous system, Caenorhabditis elegans is a good model system in which to understand how the dynamics of neural activity control this search behaviour. Extensive work on the nematode has identified the neurons that are necessary for the different locomotory behaviours underlying chemotaxis through the use of laser ablation, activity recording in immobilized animals and the study of mutants.

This paper examines the relationship between organisational and individual variables within the context of employees’ environmental behaviour in the workplace. It also explores the changes in employees’ behaviour, and perceptions of organisational support and incentives, after exposure to an environmental intervention (i.e. heating/cooling campaign and recycling campaign in the workplace). The intervention was designed by Global Action Plan, the UK’s leading environmental charity, and finding...
The interest in the thermal behaviour of the fuel mainly comes from the safety criterion which prohibit any fuel melting in the pins. Due to the gap lying between fuel and cladding, the highest temperatures are most probably occurring at Beginning Of Life (BOL) before completion of the central hole formation and before any substantial gap closure has taken place. However it cannot be ruled out that after some burn up the thermal transfer between fuel and cladding becomes worse than it was at BOL Then if the power does not decrease the maximum temperature might become higher than at (BOL). In order to get an overall experimental validation of our thermal calculations we need to cover the entire range of the pin life. Actually the method cannot be the same for BOL and end of life (EOL). For BOL it is possible to get a direct thermal measure through thermocouples, but this method is no longer practical after some days due to the failure of the thermocouples under neutrons flux at the temperatures of interest. This failure may happen before or after complete gap closure is reached and the rate of gap closure is especially meaningful for the BOL thermal behaviour. Another aspect of the thermal behaviour is the statistical one which may be obtained by the post-irradiation examination of the fuel microstructure, although it is not a proper way to get the absolute temperatures in the fuel, it is one of the most direct ones to have an insight in fuel thermal dispersion at BOL and over-heating at EOL

Full Text Available The purpose of this study was to investigate the relationships between knowledge sharing behaviour and the demographic variables gender, age, organisational tenure and professional tenure. Following a correlational survey approach, the study sourced its data from senior secondary school teachers in and around Gaborone, Botswana. Knowledge sharing behaviour was measured using an instrument sourced from the extant literature. No statistically significant relationship was detected between knowledge sharing behaviour and gender, age, or professional tenure. Only organisational tenure weakly negatively correlated with knowledge sharing behaviour. Thus, according to these findings, demographic variables do not appear to be important determinants of knowledge sharing behaviour.
The present study investigated exercise behaviour over a six-week period in a theory of planned behaviour context, extended with implementation intentions, dispositional variables, and past behaviour. Two waves of questionnaires were used to measure behavioural intention, perceived behavioural control, past behaviour, and three dispositional variables, that is optimism, self-efficacy and action-orientation, as well as actual performance of exercise behaviour. Implementation intentions were ma...

The causes of suicidal behaviour are not fully understood; however, this behaviour clearly results from the complex interaction of many factors. Although many risk factors have been identified, they mostly do not account for why people try to end their lives. In this Review, we describe key recent developments in theoretical, clinical, and empirical psychological science about the emergence of suicidal thoughts and behaviours, and emphasise the central importance of psychological factors. Personality and individual differences, cognitive factors, social aspects, and negative life events are key contributors to suicidal behaviour. Most people struggling with suicidal thoughts and behaviours do not receive treatment. Some evidence suggests that different forms of cognitive and behavioural therapies can reduce the risk of suicide reattempt, but hardly any evidence about factors that protect against suicide is available. The development of innovative psychological and psychosocial treatments needs urgent attention. PMID:26360404

There is an incompatibility between how transport engineers think drivers behave in roadworks and how they actually behave. As a result of this incompatibility we are losing approximately a lane's worth of capacity in addition to those closed by the roadworks themselves. The problem would have little significance were it not for the fact a lane of motorway costs approx. £30 m per mile to construct and £43 k a year to maintain, and that many more roadworks are planned as infrastructure constructed 40 or 50 years previously reaches a critical stage in its lifecycle. Given current traffic volumes, and the sensitivity of road networks to congestion, the effects of roadworks need to be accurately assessed. To do this requires a new ergonomic approach. A large-scale observational study of real traffic conditions was used to identify the issues and impacts, which were then mapped to the ergonomic knowledge-base on driver behaviour, and combined to developed practical guidelines to help in modelling future roadworks scenarios with greater behavioural accuracy. Also stemming from the work are novel directions for the future ergonomic design of roadworks themselves. PMID:26154200

Rapid Eye Movement (REM) sleep Behaviour Disorder (RBD) is a REM sleep parasomnia characterized by loss of the muscle atonia that typically occurs during REM sleep, therefore allowing patients to act out their dreams. RBD manifests itself clinically as a violent behaviour occurring during the night, and is detected at the polysomnography by phasic and/or tonic muscle activity on the electromyography channel. In absence of neurological signs or central nervous system lesions, RBD is defined as idiopathic. Nevertheless, in a large number of cases the development of neurodegenerative diseases in RBD patients has been described, with the duration of the follow-up representing a fundamental aspect. A growing number of clinical, neurophysiologic and neuropsychological studies aimed to detect early markers of neurodegenerative dysfunction in RBD patients. Anyway, the evidence of impaired cortical activity, subtle neurocognitive dysfunction, olfactory and autonomic impairment and neuroimaging brain changes in RBD patients is challenging the concept of an idiopathic form of RBD, supporting the idea of RBD as an early manifestation of a more complex neurodegenerative process.

Full Text Available Bullying behaviour refers to repeated negative behaviour displayed by one or more person (s with the intention of hurting the feeling, personality and power of the victim. The objective of this study therefore was to find out the efficacy of Client-Centred and Rational-Emotive Behaviour Therapies in reducing bullying behaviour among in-school adolescents in Ilorin, Nigeria. The study adopted the quasi-experimental research method using a 3×2 factorial design made up of three (3 row groups (two experimental and one control. Stratified random sampling technique was used to select three secondary schools on the basis of location to prevent experimental contamination. Self-report questionnaire was used to purposively select the participants. The primary dependent variable was bullying behaviour and respondents with high score on bullying items and low scores on victimisation items were selected to participate in the treatment. The findings revealed a significant reduction in the bullying behaviour of the in-school adolescents exposed to experimental treatments; Client-Centred Therapy (CCT produced significant reduction in the bullying behaviour among the in-school adolescents, and Rational-Emotive Behaviour Therapy (REBT produced significant reduction in the bullying behaviour of the in-school adolescents. It was recommended that CCT and REBT procedures should be employed in modifying bullying behaviours.

In this theoretical paper, we investigate the importance of nonverbal behaviour in the context of leadership. Research on the decoding of social interactions has shown that the quality or type of relationship as well as relationally relevant emotional states are transmitted nonverbally. With this in mind, we review the existing literature on nonverbal leadership behaviour, such as research on Pygmalion leadership or political leadership. The nonverbal behaviours examined in these research are...
This paper considers the justifiability of criminalising anti-social behaviour through two-step prohibitions such as the Anti-Social Behaviour Order (ASBO). The UK government has recently proposed to abolish and replace the ASBO; however, the proposed new orders would retain many of its most controversial features. The paper begins by criticising the definition of anti-social behaviour employed in both the current legislation and the new proposals. This definition is objectionable because it ...

We suggest that variation in mammalian behavioural flexibility not accounted for by current socioecological models may be explained in part by developmental constraints. From our own work, we provide examples of constraints affecting variation in behavioural flexibility, not only among individuals, but also among species and higher taxonomic units. We first implicate organizational maternal effects of androgens in shaping individual differences in aggressive behaviour emitted by female spotte...

Against the background of diverse food scandals this article investigates the role of trust as a determinant of consumer behaviour in Germany. As empirical analyses indicate, the impact of trust on consumer behaviour in a quotidian and presumably safe setting is to be neglected. In the environment of a food scandal, however, trust proves to be a crucial element with regard to a more in-depth understanding of consumer behaviour under uncertainty. Moreover, it is analysed whether different valu...
To evaluate the CT findings of bronchial anthracofibrosis. Fourteen patients with bronchoscopically confirmed anthracofibrosis were involved in this study. CT findings (n=3D12) were retrospectively analysed; the pattern, distri-bution and extent of bronchial and parenchymal abnormalities and additional findings such as mediastinal lymphadenopathy and pleural effusion were assessed. Age, sex, and occupational and disease history were history were also reviewed. Patients were aged between 63 and 95 (mean, 71.3) years, and ten were female. Only one patient had an occupational history, but four had a history of pulmonary tuberculosis. Frequent radiologic findings were bronchial wall thickening(n=3D6), atelectasis(n=3D8), mediastinal lymphad-enopathy(n=3D7) and mass(n=3D4). Other accompanying findings were bronchial wall calcification(n=3D3), consolidation(n=3D2) and pleural effusion(n=3D2). Right upper (n=3D7) and right middle lobe(n=3D7) were the most commonly involved sites, and multifocal involvement (n=3D7) was frequent. Bronchial wall thickening, atelectasis and mediastinal lymphadenopathy were characteristic CT findings of anthracofibrosis. When such findings are noted in older or aged female patients, anthracofibrosis should be included in the differential diagnosis

Full Text Available This study examines online search pattern and buying behaviour in Malaysia. Malaysian consumers search moderately for product/service information with company websites being the most popular mode of searching. Books, airline tickets, and hotel room booking are the products and services commonly purchased to satisfy self-fulfillment and affiliation needs. Respondents who have online purchase experiences have a higher intention to make online purchase in the future. There is no gender difference in terms of the frequency of online search and purchase as well as the type of consumer needs being satisfied over the Internet. Implications of the research findings and suggestions for future research are discussed. Keywords: online search behaviour; online purchase; online ads; Malaysia
The objective of this publication is to provide an up to date review of the environmental behaviour of radium, including methods for analysis, assessment and control. The need for a reference text on the subject was identified at an early stage of the International Atomic Energy Agency's Co-ordinated Research Programme (CRP) on radium behaviour in relation to uranium mining and milling wastes, which began in 1976. There were two CRPs: (1) The Source, Distribution, Movement and Deposition of Radium in Inland Waterways and Aquifers (1976-1980; final report: IAEA-TECDOC-301, published in 1984). (2) The Environmental Migration of Radium and Other Contaminants Present in Liquid and Solid Wastes from the Mining and Milling of Uranium (1981-1985; final report: IAEA-TECDOC-370, published in 1986). This publication deals with the sources, properties, environmental behaviour and the methods of analysis, control and assessment of 226Ra. It is an outgrowth of Agency programmes directed towards the environmental problems involved in uranium mining and milling. The emphasis in several of the sections reflects these origins. For example, many of the contributions in Volume 2 of this report on technologically enhanced sources of radium (Part 1), methods of control and abatement (Part 2) and the impact on man (Part 3) are concerned with uranium mining and milling. In Volume 1, coverage of the natural distribution (Part 2), analytical methods (Part 3), environmental migration (Part 4) and biological uptake (Part 5), is more general. It is likely that the reader will find the information needed on the environmental behaviour of radium in this report, or will at least find references to other, more appropriate, texts contained in it.

Full Text Available This study investigates the differences between individualism-collectivism and consumer behaviour in relationto automobile purchases. In this study the author looked at several stages of the consumer decision-makingprocess and identified the possible differences between individualist and collectivist consumers and how itinfluences purchase decision. Based on a sample of 211 respondents from individualist (Australian-born andcollectivist (Asian-born backgrounds, an established scale (Cultural Values Scale: Singelis, Triandis, Bhawuk,& Gelfand, 1995 was used to confirm the cultural values among the participants, if the respondents are alignedwith the particular group (i.e. Asian-born with collectivism and Australian-born with individualism.Hypotheses were tested using independent sample t-test. Results found that there were no differences inindividualism observed between Australian-born and Asian-born respondents; however, there were differencesin collectivism observed between these two groups, such that Asian-born participants scored higher oncollectivism. Results also found that Asian-born consumers are more brand conscious and involve a number offamily/friends in their decision making. In contrast Australian-born consumers do not believe in group decisionmaking and uses internet as the most important source of information. The findings will provide insight intohow automobile companies could position themselves with respect to their marketing strategies in differentcultural settings.
Full Text Available The long-term effects of behaviour and environmental exposures, particularly during childhood, on health outcomes are well documented. Particularly thought provoking is the notion that exposures to different social environments have a long-lasting impact on human physical health. However, the mechanisms mediating the effects of the environment are still unclear. In the last decade, the main focus of attention was the genome, and interindividual genetic polymorphisms were sought after as the principal basis for susceptibility to disease. However, it is becoming clear that recent dramatic increases in the incidence of certain human pathologies, such as asthma and type 2 diabetes, cannot be explained just on the basis of a genetic drift. It is therefore extremely important to unravel the molecular links between the "environmental" exposure, which is believed to be behind this emerging incidence in certain human pathologies, and the disease's molecular mechanisms. Although it is clear that most human pathologies involve long-term changes in gene function, these might be caused by mechanisms other than changes in the deoxyribonucleic acid (DNA sequence. The genome is programmed by the epigenome, which is composed of chromatin and a covalent modification of DNA by methylation. It is postulated here that "epigenetic" mechanisms mediate the effects of behavioural and environmental exposures early in life, as well as lifelong environmental exposures and the susceptibility to disease later in life. In contrast to genetic sequence differences, epigenetic aberrations are potentially reversible, raising the hope for interventions that will be able to reverse deleterious epigenetic programming.
Full Text Available Purpose: The aim of the paper is to evaluate buckling instabilities behaviour of long curved thin shell. Both initially straight and curved tubes are investigated with numerical and experimental assessment methods, in the context of NPP applications with an illustrative example for IRIS LWR integrated Steam Generator (SG tubes.Design/methodology/approach: In this study structural buckling response tube with combination effects of geometric imperfections as well as initially bent shape under external pressure load are investigated using a non linear finite element (MSC.MARC FEM code formulation analysis. Moreover results are presented, extending the findings of previous research activity works, carried out at Pisa University, on thin walled metal specimen.Findings: The experiments were conducted on Inconel 690 test specimen tube. The comparison between numerical and experimental results, for the same geometry and loading conditions, shows a good agreement between the elastic-plastic finite-element predictions and the experimental data.Research limitations/implications: The presented research results may be considered preliminary in the sense that it would be important to enlarge the statistical base of the results themselves, even if they are yet certainly meaningful to highlight the real problem, considering the relatively large variability of the geometrical imperfections and bending instabilities also in high quality production tubes.Originality/value: From the point of view of the practical implication, besides the addressed problem general interest in industrial plant technology, it is worth to stress that straight and curved axis tubes are foreseen specifically in innovative nuclear reactors SG design.
This paper compares two alternative answers to the question, 'Who is the addressee of welfare economics?' These answers correspond with different understandings of the status of the normative conclusions of welfare economics, and have different implications for how welfare economics should be adapted in the light of the findings of behavioural economics. The conventional welfarist answer is that welfare economics is addressed to a 'social planner' whose objective is to maximise the overall we...

This study examined the role of person type in explaining the relationship between perceived behavioural control and behavioural intentions. Participants (N = 187) completed measures of the theory of planned behaviour (Ajzen, 1991) variables regarding 30 behaviours. Within-participants analyses demonstrated that intentions were more strongly predicted by perceived behavioural control (PBC) than a combination of attitudes and subjective norms among a minority of the sample. When these 'PBC controlled' participants were considered separately, the effects for perceived behavioural control obtained in previous between-participants analyses were augmented. Conversely, when these participants were excluded from the sample, the effects of perceived behavioural control were reduced. PBC control was also modestly associated with dispositional measures of perceived controllability. Overall, the findings indicate that the strength of the perceived behavioural control-intention relationship depends not only on the type of behaviour but also on the type of person. PMID:12133227

In spite of millions of years of evolutionary divergence, the conservation of gene function is common across distant lineages. As such, genes that are known to influence behaviour in one organism are likely to influence similar behaviours in other organisms. Recent studies of the evolution of behavi
Full Text Available AIMS: Recent literature has posed sedentary behaviour as an independent entity to physical inactivity. This study investigated whether associations between sedentary behaviour and cardio-metabolic biomarkers remain when analyses are adjusted for total physical activity. METHODS: Cross-sectional analyses were undertaken on 4,618 adults from the 2003/04 and 2005/06 U.S. National Health and Nutrition Examination Survey. Minutes of sedentary behaviour and moderate-to-vigorous physical activity (MVPA, and total physical activity (total daily accelerometer counts minus counts accrued during sedentary minutes were determined from accelerometry. Associations between sedentary behaviour and cardio-metabolic biomarkers were examined using linear regression. RESULTS: Results showed that sedentary behaviour was detrimentally associated with 8/11 cardio-metabolic biomarkers when adjusted for MVPA. However, when adjusted for total physical activity, the associations effectively disappeared, except for C-reactive protein, which showed a very small, favourable association (β = -0.06 and triglycerides, which showed a very small, detrimental association (β = 0.04. Standardised betas suggested that total physical activity was consistently, favourably associated with cardio-metabolic biomarkers (9/11 biomarkers, standardized β = 0.08-0.30 while sedentary behaviour was detrimentally associated with just 1 biomarker (standardized β = 0.12. CONCLUSION: There is virtually no association between sedentary behaviour and cardio-metabolic biomarkers once analyses are adjusted for total physical activity. This suggests that sedentary behaviour may not have health effects independent of physical activity.

This paper investigates the relationship between personality traits and health behaviours in adolescence using a large and recent cohort study. In particular, we investigate the impact of locus of control, self-esteem and work ethics at ages 15-16 years on the incidence of health behaviours such as alcohol consumption, cannabis and other drug use, unprotected and early sexual activity and sports and physical activity. We use matching methods to control for a very rich set of adolescent and family characteristics, and we find that personality traits do affect health behaviours. In particular, individuals with external locus of control, low self-esteem or with low levels of work ethics seem more likely in engage in risky health behaviours. PMID:24677274

This paper explains the perceived implementation behaviour of counties in the United States with respect to the National Incident Management System (NIMS). The system represents a massive and historic policy mandate designed to restructure, standardise and thereby unify the efforts of a wide variety of emergency management entities. Specifically, this study examined variables identified in the NIMS and policy literature that might influence the behavioural intentions and actual behaviour of counties. It found that three key factors limit or promote how counties intend to implement NIMS and how they actually implement the system: policy characteristics related to NIMS, implementer views and a measure of local capacity. One additional variable-inter-organisational characteristics-was found to influence only actual behaviour. This study's findings suggest that the purpose underlying NIMS may not be fulfilled and confirm what disaster research has long suggested: the potential for standardisation in emergency management is limited.

The purposes of our study were to find out characteristic ultrasonographic findings of gynecomastia and to analyze age distribution, causative factors of gynecomastia. For these purposes, medical records of 39 male patients with gynecomastia were reviewed and sonographic findings of 13 cases of gentamycin were analyzed. Gynecomastia was found most commonly in teenagers and commonly in twenties. Almostly, it occurred without any evident etiology and classified as idiopathic or pirbuterol type. Less frequently, it occurred due to drug administration, systemic disease, or male hormone deficiency. Unilateral involvement was seen in 29 cases; 17cases involving the left and 12 cases the right. Bilateral involvement was seen in 10 cases. Sonographically,gynecomastia appeared as hypoechoic or intermediate echoic mass with various shape in the subareolar area. One case showed diffuse fatty breast pattern without definable mass. On sonographic evaluation, prominent nipple should not be misinterpreted as a breast mass. For the correct diagnosis of gynecomastia, both side breasts should be evaluated for comparison
This paper examines the conceptual divide between energy saving behaviours in the home, relating to purchase-oriented behaviours and habitual action to conserve energy. Considerable empirical research indicates that this divide is of utility when characterising energy saving behaviour. However, little attention has been focused around the association between energy saving behaviours and other environmental actions. Accordingly, this paper examines the structural bases of energy conservation behaviours in the wider context of environmental behaviour. These findings are then used to examine the characteristics of energy savers as they relate to other environmental actions. Using cluster analysis, the paper defines a range of behavioural characteristics that transcend energy saving and other environmental actions. The use of such an approach to policy makers seeking to encourage energy conservation practices is discussed at the end of the paper

Ganglioneuroma is a relatively uncommon benign tumor and has no pathognomonic radiological findings;diagnosis is therefore difficult. In order to better diagnose this tumor we analysed its CT findings and pathologic correlation. Seventeen tumors in 16 patients(M:F=3D9:7) diagnosed as ganglioneuroma between 1992 and 1996 were retrospectively analysed with regard to location, size, contour, long axis of the mass, enhancement pattern, calcification, necrosis and capsulation, all as seen on CT, and compared with histo-pathologic findings. Tumors were 1.5 to 10(mean, 5.6) cm in size, and their location was mediastinal(n=3D12), cervical(n=3D2), retroperitoneal (n=3D2) or adrenal(n=3D1). Fifteen had an oval or round contour and two were dumb-bell-shaped. The long axis of the lesion was craniocaudal in 14 cases and non-specific in three. Thirteen lesions showed heterogeneous enhancement, and four homogeneous. Capsule-like enhancement was noted on CT scans in eight cases;there was no definite correlation between enhancement pattern and pathologic findings. Calcification was seen in six cases and an inner low-density lesion in two. Ganglioneuroma is a benign neurogenic tumor, occurring most frequently at the posterior mediastinum. General CT findings of this tumor are a well-defined oval shape with a variable enhancement pattern, but several cases showed focal calcification or inner low density. For accurate diagnosis of ganglioneuroma both common and uncommon findings must therefore be considered.=20.
The authors report three cases of intrathoracic foreign body that is defined as a cotton matrix mass, mostly retained surgical sponge, a rare complication of a thoracic surgery. The patients were evaluated by chest radiography and computed tomography with the imaging findings confirmed after thoracotomy and anatomopathological study. The mainly imaging findings consisted of intrathoracic masses in patients with previous thoracic surgery that return to hospital with lower respiratory tract symptoms in different period after surgery procedure. The three cases were related with a brief review of the literature. (author)

The problem of attribute reduction is an important problem related to feature selection and knowledge discovery. The problem of finding reducts with minimum cardinality is NP-hard. This paper suggests a new algorithm for finding exact reducts with minimum cardinality. This algorithm transforms the initial table to a decision table of a special kind, apply a set of simplification steps to this table, and use a dynamic programming algorithm to finish the construction of an optimal reduct. I present results of computer experiments for a collection of decision tables from UCIML Repository. For many of the experimented tables, the simplification steps solved the problem.

We investigated whether provision of additional appetitive and consummatory elements of foraging reduces baseline stress and abnormal behaviour – in terms of fur-chewing and stereotypic behaviour – in farmed mink. We studied 200 juveniles (n = 100 females and 100 males) during the 5-month growth......; (iii) CONS, chunky feed (parts up to 42 mm), replacing conventional feed; (iv) BOTH, access to both biting ropes and chunky feed. In growing mink, biting ropes reduced fur-chewing (P = 0.044) and chunky feed reduced stereotypic behaviour (P = 0.038) and fur-chewing in female mink (P = 0.019). During......, stereotypic behaviour was reduced by provision of chunky feed, increasing the consummatory element in daily foraging. Fur-chewing was reduced upon access to either biting ropes or chunky feed in female mink throughout the study. Our findings support frustrated foraging, mainly consummatory, behind abnormal...

To evaluate the characteristic CT findings of neuroblastoma, we studied neuroblastomas. We analysed CT findings of available 25 cases among pathologically proved 51 neuroblastomas from Jan. 1983 to Sept. 1990. The most frequent site of origin is adrenal gland (40%) and the second is retroperitoneum (32%) and the third ismediastinum (16%). Characteristic CT findings are as follows: Calcifications within the tumor is detected in 86% of abdominal neuroblastomas and 50% of mediastinal origin. Hemorrhagic and necrotic changes within the tumor is noted at 86% in the tumor of abdominal origin and 25% in mediastinal neuroblastomas. Contrast enhanced study showed frequently seperated enhanced appearance with/without solid contrast enhancement. Encasements of major great vessels such as aorta and IVC with/without displacement by metastatic lymph nodes or tumor are frequently seen in 90% of abdominal neuroblastomas. Multiple lymphadenopathy are detected in 95% of abdominal neuroblastomas and 25% of mediastinal neuroblastomas. The most common organ or contiguous direct invasion is kidney in 6 cases and the next one is liver but intraspinal canal invasion is also noted in 2 cases. We concluded that diagnosis of neuroblastoma would be easily obtained in masses of pediatric group from recognition of above characteristic findings.

Purpose: To evaluate the radiological, ultrasonographic, and magnetic resonance imaging (MRI) findings of idiopathic granulomatous mastitis. Material and Methods: Between April 2002 and June 2005, the mammography, ultrasound, color Doppler ultrasound, non enhanced MR, and dynamic MR findings of nine patients with the preliminary clinical diagnosis of malignancy and the final diagnosis of granulomatous mastitis were evaluated. Results: On mammography, asymmetrical focal densities with no distinct margins, ill-defined masses with spiculated contours, and bilateral multiple ill-defined nodules were seen. On ultrasound, in four patients a discrete, heterogenous hypoechoic mass, in two patients multiple abscesses, in one patient bilateral multiple central hypo peripheral hyperechoic lesions, in two patients heterogeneous hypo- and hyperechoic areas together with parenchymal distortion, and in one patient irregular hypoechoic masses with tubular extensions and abscess cavities were seen. Five of the lesions were vascular on color Doppler ultrasound. On MR mammography, the most frequent finding was focal or diffuse asymmetrical signal intensity changes that were hypointense on T1W images and hyperintense on T2W images, without significant mass effect. Nodular lesions were also seen. On dynamic contrast-enhanced mammography, mass-like enhancement, ring-like enhancement, and nodular enhancement were seen. The time-intensity curves differed from patient to patient and from lesion to lesion. Conclusion: The imaging findings of idiopathic granulomatous mastitis have a wide spectrum, and they are inconclusive for differentiating malignant and benign lesions.

Existing Analytical Frameworks for Information Behaviour Don’t Fully Explain HIV/AIDS Information Exchange in Rural Communities in Ontario, Canada. A Review of: Veinot, T., Harris, R., Bella, L., Rootman, I., & Krajnak, J. (2006. HIV/AIDS Information exchange in rural communities: Preliminary findings from a three‐province study. Canadian Journal of Information and Library Science, 30(3/4, 271‐290.
Full Text Available Objective – To explore and analyze, against three theoretical frameworks of information behaviours, how people with HIV/AIDS, their friends, and their family living in rural communities find information on HIV/AIDS.Design – Qualitative, individual, in‐depth, semi‐structured interviews.Setting – Two rural regions in Ontario, Canada.Subjects – Sixteen participants; 10 people with HIV/AIDS (PHAs and 6 family members or friends.Methods – Participants were recruited through health care providers, social service agencies and through snowball sampling. Semi‐structure interviews were conducted focusing on participants’ experience with HIV/AIDS, how they find and use information on HIV/AIDS, networks for information exchange and the effect of technology on information exchange. Interviews were taped, transcribed, analyzed qualitatively using NVivo software. Results were compared to three theoretical frameworks for information behaviour: 1. purposeful information seeking (i.e., the idea that people purposefully seek information to bridge perceived knowledge gaps; 2. non‐purposeful or incidental information acquisition (i.e., the idea that people absorb information from going about daily activities; and 3. information gate keeping (i.e., the concept of private individuals who act as community links and filters for information gathering and dissemination.Main Results – Consistent with the theories:•PHAs prefer to receive information from people they have a personal relationship with, particularly their physician and especially other PHAs.•PHAs’ friends and families rely on their friends and family for information, and are particularly reliant upon the PHA in their lives.•Fear of stigma and discrimination cause some to avoid seeking information or to prefer certain sources of information, such as healthcare providers, who are bound by codes of professional conduct.•Emotional support is important in information provision and

The BetterPoints system is unique in it’s flexibility and ability to draw on multiple behaviour change models to create high quality interventions. Early findings from existing programmes being implemented for Local Authorities in the UK suggest that BetterPoints can demonstrate real-world behaviour change. We would like to work with academic partners to further investigate these real-world changes in behaviour and establish a robust evidence base.
