    Psychotherapy not only has positive but also negative effects, which is especially true for group psychotherapy due to psychodynamic and interactional processes. Using the UE-G questionnaire 71 patients who participated in cognitive behavioral group psychotherapy reported on negative experiences in the context of the group therapy. The answers were then validated in a qualitative interview. Of the patients 98.6% reported about at least one negative experience and 43.7% about severe or extremely severe negative experiences. Most prominent was the induction of hopelessness and demoralization by what patients saw and heard from other patients in the group. Burdensome and therefore undesired treatment effects are regularly seen in group psychotherapy, because of treatment or patient related factors. In any case they must be taken into account during treatment, in the training of group psychotherapists and in quality control.

    To evaluate the effect of group cognitive behavioral therapy (GCBT) on social anxiety disorders (SAD). A total of 50 patients with SAD were recruited in this study. A survey containing the Liebowitz social anxiety scale (LSAS),the automatic thoughts questionnaire (ATQ),the fear of negative evaluation questionnaire (FNE),the social support rating scale (SSRS),the tridimensional personality questionnaire (TPQ),and the egna minnen barndoms uppfostran (EMBU) was administered before and (one week) after the GCBT,including in the 50 healthy controls. About 21 patients completed the eight-week GCBT (once a week,2 h a session). Follow-up surveys were conducted on 40 patients (22 patients treated with GCBT and 18 untreated) over a 1-5 year period. Significant differences were found between the SAD patients and healthy controls in thinking mode,personality characteristics,social support,parental rearing styles,and social anxiety symptoms. Significant decrease in social anxiety symptom ( t =4.06, P =0.000) , negative automatic thoughts ( t =4.58, P =0.000) and fear for rejection ( t =3.85, P =0.000) were observed after the GCBT therapy. Such improvement was positively correlated with subjective social support ( r =0.361, P =0.022) ,and negatively correlated with rejection of father ( r =-0.431, P =0.005) . There was also statistical difference between the patients with and without the GCBT therapy ( P =0.033) . GCBT treatment can relieve SAD symptoms by changing the negative cognitive of SAD patients. Social support and rejection of father affects the prognosis of SAD.

    2009-12-01

    The authors investigated the mechanism of group cohesion in the relationship between (a) task interdependence and goal interdependence and (b) individuals' organizational citizenship behavior (OCB). The authors adopted a multilevel perspective to facilitate understanding of the complex relations among variables. They collected data from 53 supervisors and 270 employees from R&D departments in Taiwan. The authors found that group cohesion fully mediated the effects of task interdependence and goal interdependence on employees' OCB. In addition, task interdependence had a greater effect on group cohesion than did goal interdependence. The authors discuss implications and suggestions for future research.

    To compare the effects of constructivism-based dietary group counseling transmitted through videoconferencing (VC) and face-to-face (FF) counseling on changes in eating behaviors. Altogether, 74 participants with high risk of type 2 diabetes were divided into FF and VC groups based on their place of residence in northern Finland. Constructivism-based dietary group counseling, a nonrandomized intervention, was performed (evaluations at 0, 6, and 21 months). The Three-Factor Eating Questionnaire-18 was used to evaluate cognitive restraint eating (CR), emotional eating (EE), and uncontrolled eating (UE). Data were analyzed using ANOVA and ANCOVA (significance level of 0.05). Cognitive restraint eating increased and UE decreased between baseline and 6 months in both groups, but between baseline and 21 months only in the FF group (P = .005 and P = .021, respectively). Emotional eating decreased only in the VC group (P = .016). There were no differences between groups at 6 or 21 months. Constructivism-based counseling delivered through videoconferencing was effective at improving eating behaviors. Copyright © 2015 Society for Nutrition Education and Behavior.

    Depression is an important target of psychological assessment in patients with end-stage renal disease because it predicts their morbidity, mortality, and quality of life. We assessed the effectiveness of cognitive-behavioral therapy in chronic hemodialysis patients diagnosed with major depression by the Mini International Neuropsychiatric Interview (MINI). In a randomized trial conducted in Brazil, an intervention group of 41 patients was given 12 weekly sessions of cognitive-behavioral group therapy led by a trained psychologist over 3 months while a control group of 44 patients received the usual treatment offered in the dialysis unit. In both groups, the Beck Depression Inventory, the MINI, and the Kidney Disease and Quality of Life-Short Form questionnaires were administered at baseline, after 3 months of intervention or usual treatment, and after 9 months of follow-up. The intervention group had significant improvements, compared to the control group, in the average scores of the Beck Depression Inventory overall scale, MINI scores, and in quality-of-life dimensions that included the burden of renal disease, sleep, quality of social interaction, overall health, and the mental component summary. We conclude that cognitive-behavioral group therapy is an effective treatment of depression in chronic hemodialysis patients.

    Full Text Available In order to effectively depict the group evacuation behavior in the complicated three-dimensional space, a novel pedestrian flow model is proposed with three-dimensional cellular automata. In this model the calculation methods of floor field and fire gain are elaborated at first, and the transition gain of target position at the next moment is defined. Then, in consideration of pedestrian intimacy and velocity change, the group evacuation strategy and evolution rules are given. Finally, the experiments were conducted with the simulation platform to study the relationships of evacuation time, pedestrian density, average system velocity, and smoke spreading velocity. The results had shown that large-scale group evacuation should be avoided, and in case of large pedestrian density, the shortest route of evacuation strategy would extend system evacuation time.

    To assess the seminal characteristics as well as the sexual behavior of men of various age groups to establish the presence of an aging effect on those characteristics. Semen samples were collected from men (n = 792) undergoing in vitro fertilization or intrauterine insemination in cases of female factor infertility only. Samples were collected using a seminal collection device at intercourse and evaluated manually according to World Health Organization (WHO) standards. Men were divided into four groups according to their ages: (i) 20-30, (ii) 31-40, (iii) 41-50 and (iv) 51-60 years, and their seminal characteristics and responses to a sexual behavior questionnaire were compared. The data showed statistically significant differences in the seminal characteristics tested, most notably in the sperm concentration, motility, grade of motility, hypo-osmotic swelling and normal sperm morphology. Furthermore, the decline in normal sperm morphology with age was more pronounced when using strict criteria rather than WHO standards. There were also differences in total sperm count, total motile sperm and total functional sperm fraction (assessed by both WHO and strict criteria). Significant differences were also observed in the sexual behavior patterns in older men in terms of the number of years they have been trying to conceive, sexual frequency and sexual satisfaction. The data clearly illustrate an aging effect on semen characteristics and sexual behavior in men as they age. It is suggested that the aging effect be taken into consideration when proposing normal standard values for semen characteristics in routine semen analysis as outlined by WHO standards.

    Full Text Available : This study aimed to investigate the effectiveness of group cognitive-behavioral therapy on aggression among addicts. Method: A quasi-experimental design along with pre-posttest stages, control group, and follow-up was employed for the conduct of this study. The number of 24 addicts referring to rehabilitation clinics in Tehran was selected as the sample size of this study via convenience sampling method in accordance with the inclusion criteria. These participants were randomly assigned to experimental and control groups. In this study, Buss-Perry Aggression Questionnaire was used for data collection purposes. Results: Data analysis showed that group cognitive-behavioral therapy reduces verbal and physical aggression, anger, and hostility in addicted people. However, this therapy only led to the reduction of verbal aggression, anger, and hostility in addicted people. Conclusion: Since aggression has a high comorbidity with substance abuse, this factor can be as an obstacle to withdrawal. Therefore, it must be considered in addiction treatment.

    There is evidence that the stigma surrounding mental illness may be greater in Japan than elsewhere. However, few Japanese studies have focused on self-stigma (the internalization of social stigma), and few interventions to reduce self-stigma exist. To remedy this deficiency, we evaluated the efficacy of group cognitive-behavioral therapy (CBT) in reducing self-stigma and examined the relationship between cognitive restructuring and self-stigma. We administered a 10-session group CBT program to 46 Japanese outpatients with anxiety and depressive symptoms (36 men, 10 women; mean age=38.57 years, SD=8.33; 20 diagnosed with mood disorders; 24 with neurotic, stress-related, or somatoform disorders; and 2 with other disorders). A pretest-posttest design was used to examine the relationship between cognitive restructuring and self-stigma. Outcomes were measured using the Japanese versions of the Devaluation-Discrimination Scale, Dysfunctional Attitude Scale, Beck Depression Inventory-II, State-Trait Anxiety Inventory State-Form, and Rosenberg's Self Esteem Scale. Participants exhibited significant improvements in depression, anxiety, and maladjusted cognitive bias and reductions in self-stigma. Cognitive bias was significantly correlated with self-stigma. Group CBT is effective in improving both emotional symptoms and self-stigma in outpatients with anxiety and depressive symptoms. Reduction in self-stigma plays a mediating role in alleviating emotional symptoms and improving cognition. Copyright © 2014 Elsevier B.V. All rights reserved.

    Primary care is where many patients with insomnia first ask for professional help. Cognitive-behavioral therapy for insomnia (CBT-I) is the recommended treatment for chronic insomnia. Although CBT-I's efficacy is well established, its effectiveness in real-life primary care has seldom been investigated. We examined the effectiveness of CBT-I as routinely delivered in a Canadian primary care setting. The patients were 70 women and 11 men (mean age = 57.0 years, SD = 12.3); 83% had medical comorbidity. For the first 81 patients who took the six-session group program we compared initial and postprogram sleep diaries, sleep medication use, Insomnia Severity Index (ISI), the Hospital Anxiety and Depression Scale (HADS), and visits to the family physician. Sleep onset latency, wake after sleep onset, total sleep time, sleep efficiency, and ISI scores improved significantly (p 7). Wait-list data from 42 patients showed minimal sleep and mood improvements with the passage of time. Number of visits to the family physician six months postprogram decreased, although not significantly (p = .108). The CBT-I program was associated with improvement on all sleep and mood measures. Effect sizes were similar to, or larger than, those found in randomized controlled trials, demonstrating the real-world effectiveness of CBT-I in an interdisciplinary primary care setting.

    Social life is regulated by norms of fairness that constrain selfish behavior. While a substantial body of scholarship on prosocial behavior has provided evidence of such norms, large inter- and intra-personal variation in prosocial behavior still needs to be explained. The article identifies two social-structural dimensions along which people's generosity varies systematically: group attachment and social position. We conducted lab-in-the-field experiments involving 2,597 members of producer organizations in rural Uganda. Using different variants of the dictator game, we demonstrate that group attachment positively affects prosocial behavior, and that this effect is not simply the by-product of the degree of proximity between individuals. Second, we show that occupying a formal position in an organization or community leads to greater generosity toward in-group members. Taken together, our findings show that prosocial behavior is not an invariant social trait; rather, it varies according to individuals' relative position in the social structure.

    Full Text Available Studies on the adoption and maintenance of group exercise behavior are scarce. The objective of this study is to test two self-efficacy based interventions to increase barrier self-efficacy and group exercise behavior. In total 122 participants (Mage 42.02 yr.; SD 12.29; 67% females were recruited and randomly assigned to one control and two experimental groups. The control group was limited to participate in one virtual group exercise program only (group 1. The first experimental group was able to self-set their activities and participate in multiple group exercise programs (group 2. The second experimental group received an additional monthly coaching protocol to manage self-set goals (group 3. A validated scale for barrier self-efficacy was used, group exercise sessions were measured and drop-out rates were registered. An ANOVA indicated that mean amount of sessions of group 1 and 3, and 2 and 3 differed significantly (p < 0.05 in 12 weeks. Descriptive statistics demonstrate mean group exercise sessions over the total of 12 weeks of 2.74 (SD 4.65 in the control group; 4.75 (SD 6.08 in the first experimental group, and 12.25 (SD 9.07 for the second experimental group. Regression analysis indicated that self-efficacy at 8-weeks explained the highest variance in overall group exercise sessions (R2 = 0.18; p < 0.05. Overall drop-out rates were 88% in group 1, 78% in group 2 and 48% in group 3. The results showed that group exercise behavior can significantly be improved by a coaching protocol on self-set goals. Future research should address the effectiveness of self-set activities and self-set goals for a longer period of time and in other types of exercise programs.

    Squirrel monkeys display an interest in novel places, habituate to new situations, and spend most of their daily activity in the wild in large groups engaging in feeding behaviors over a broad area. Captivity limits these behaviors and consequently may disrupt normal social organizations. In captivity, squirrel monkeys may exhibit stereotypical behaviors that are believed to indicate decreased psychologic well-being. When a monkey's behavior can be made to approach that seen in the wild, and stereotypical behaviors are minimal, it is assumed that psychologic well-being is adequate. Environmental enrichment devices have been used to address the Animal Welfare Act requirement that psychologic well-being of captive nonhuman primates be considered. The purpose of the study reported here was to examine whether various environmental enrichment devices improve the psychologic well-being of captive squirrel monkeys. In the study, we used behavioral observation to quantify the effectiveness of several environmental enrichment devices for reducing stereotypical behaviors in squirrel monkeys housed alone or in groups. Analysis of our results revealed that the environmental enrichment devices did not affect the expression of normal or stereotypical behaviors, but that the type of housing did.

    Many patients with end-stage renal disease (ESRD) undergoing hemodialysis (HD) experience depression. Depression influences patient quality of life (QOL), dialysis compliance, and medical comorbidity. We developed and applied a group cognitive behavioral therapy (CBT) program including mindfulness meditation for ESRD patients undergoing HD, and measured changes in QOL, mood, anxiety, perceived stress, and biochemical markers. We conducted group CBT over a 12-week period with seven ESRD patients undergoing HD and suffering from depression. QOL, mood, anxiety, and perceived stress were measured at baseline and at weeks 8 and 12 using the World Health Organization Quality of Life scale, abbreviated version (WHOQOL-BREF), the Beck Depression Inventory II (BDI-II), the Hamilton Rating Scale for Depression (HAM-D), the Beck Anxiety Inventory (BAI), and the Perceived Stress Scale (PSS). Biochemical markers were measured at baseline and after 12 weeks. The Temperament and Character Inventory was performed to assess patient characteristics before starting group CBT. The seven patients showed significant improvement in QOL, mood, anxiety, and perceived stress after 12 weeks of group CBT. WHOQOL-BREF and the self-rating scales, BDI-II and BAI, showed continuous improvement across the 12-week period. HAM-D scores showed significant improvement by week 8; PSS showed significant improvement after week 8. Serum creatinine levels also improved significantly following the 12 week period. In this pilot study, a CBT program which included mindfulness meditation enhanced overall mental health and biochemical marker levels in ESRD patients undergoing HD.

    Full Text Available BACKGROUND AND OBJECTIVE: Cancers are a broad group of diseases, each having their own etiology, treatment, and prognosis. The majority of cancer patients experience a period of mental stress during their disease. Given the effective role of life expectancy in dealing with chronic diseases, such as stomach cancer, this study aimed to evaluate the effects of cognitive-behavioral group therapy on increased life expectancy of male patients with gastric cancer. METHODS: This quasi-experiment was conducted on 92 male patients with gastric cancer referring to Tuba Medical Center, Sari, Iran in 2014. Patients were randomly divided into two groups of test (n=46 and control (n=46. The two groups completed the Adult Hope Scale (AHS by Snyder in pretest stage. At the next stage, samples of the test group were exposed to 10 sessions of cognitive-behavioral group therapy (each session: 90 min, while the control group did not receive any special treatment. Both study groups completed the questionnaire again at the posttest stage, followed by the comparison of results. FINDINGS: In terms of life expectancy, mean scores of the test and control groups at the pretest stage were 37.21±4.7 and 36.26±4.73, respectively. Meanwhile, mean scores of the mentioned groups at the posttest stage were 40.02±3.87 and 36.23±4.8, respectively. A significant increase was observed in the mean scores of test and control groups at the posttest stage compared to before the intervention. Moreover, a significant difference was found between the study groups regarding life expectancy and its components (p<0.01. CONCLUSION: According to the results, cognitive-behavioral group therapy could increase life expectancy in patients with gastric cancer.

    Effectiveness of the condensed Dialectical Behavior Therapy Skills Training Group (DBTSTG) was compared to the Cognitive Therapy Group (CTG) in reducing depression and suicide reattempt, and modifying emotion regulation strategies among those with borderline personality disorder (BPD). Eighty-two depressed BPD college students with a suicidal history within the past six-months were randomly allocated to DBTSTG or CTG. Both groups had similar reductions in suicide reattempts and depression after the intervention and 6-month follow-ups. However, the CTG showed improvements in cognitive errors, but the DBTSTG revealed increases in acceptance and decreases in suppression scores. Both groups were effective in decreasing depression and suicide reattempt in BPD college students, probably through increasing adaptive antecedent-focused or response-focused strategies of emotion regulation, respectively.

    The modification effects of the groups amino (NH2) and nitro (NO2) on the spin polarized transport properties of the cobalt benzene-porphyrin-benzene (Co-BPB) molecule coupled to gold (Au) nanowire electrodes are investigated by the nonequilibrium Green’s function method combined with the density functional theory. The calculation results show that functional groups can lead to the significant spin-filter effect, enhanced low-bias negative differential resistance (NDR) behavior and novel reverse rectifying effect in Co-BPB molecular junction. The locations and types of functional groups have distinct influences on spin-polarized transport performances. The configuration with NH2 group substituting H atom in central porphyrin ring has larger spin-down current compared to that with NO2 substitution. And Co-BPB molecule junction with NH2 group substituting H atom in side benzene ring shows reverse rectifying effect. Detailed analyses confirm that NH2 and NO2 group substitution change the spin-polarized transferred charge, which makes the highest occupied molecular orbitals (HOMO) of spin-down channel of Co-BPB closer to the Fermi level. And the shift of HOMO strengthens the spin-polarized coupling between the molecular orbitals and the electrodes, leading to the enhanced spin-polarized behavior. Our findings might be useful in the design of multi-functional molecular devices in the future.

Second, we show that occupying a formal position in an organization or community leads to greater generosity toward in-group members. Taken together, our findings show that prosocial behavior is not an invariant social trait; rather, it varies according to individuals' relative position in the social structure.

    The nature of the phase transition in a system of self-propelling particles has been extensively studied during the past few decades. A theoretical model was proposed by [T. Vicsek et al. Phys. Rev. Lett. 75, 1226 (1995)PRLTAO0031-900710.1103/PhysRevLett.75.1226] with a simple rule for updating the direction of motion of each particle. Based on the model of Vicsek et al., in this paper, we consider a group of animals as particles moving freely in a two-dimensional space. Due to the fact that the viewable area of animals depends on the species, we consider the motion of each individual within an angle φ=ϕ/2 (ϕ is called the angle of view) of a circle centered at its position of radius R. We obtained a phase diagram in the space (φ,η_{c}) with η_{c} being the critical noise. We show that the phase transition exists only in the case of a wide view's angle φ≥0.5π. The flocking of animals is a universal behavior of the species of prey but not the one of the predator. Our simulation results are in good agreement with experimental observation [C. Beccoa et al., Physica A 367, 487 (2006)PHYADX0378-437110.1016/j.physa.2005.11.041].

    1994-05-01

    A real-space effective-field renormalization-group method (ERFG) recently derived for computing critical properties of Ising spins is extended to treat the quantum spin-1/2 anisotropic Heisenberg model. The formalism is based on a generalized but approximate Callen-Suzuki spin relation and utilizes a convenient differential operator expansion technique. The method is illustrated in several lattice structures by employing its simplest approximation version in which clusters with one (N'=1) and two (N=2) spins are used. The results are compared with those obtained from the standard mean-field (MFRG) and Migdal-Kadanoff (MKRG) renormalization-group treatments and it is shown that this technique leads to rather accurate results. It is shown that, in contrast with the MFRG and MKRG predictions, the EFRG, besides correctly distinguishing the geometries of different lattice structures, also provides a vanishing critical temperature for all two-dimensional lattices in the isotropic Heisenberg limit. For the simple cubic lattice, the dependence of the transition temperature Tc with the exchange anisotropy parameter Δ [i.e., Tc(Δ)], and the resulting value for the critical thermal crossover exponent φ [i.e., Tc≂Tc(0)+AΔ1/φ ] are in quite good agreement with results available in the literature in which more sophisticated treatments are used.

    Depression is a common psychological problem in adolescence. Recent research suggests that group cognitive-behavioral interventions can reduce and prevent symptoms of depression in youth. Few studies have tested the effectiveness of such interventions when delivered by school teachers and counselors (as opposed to research team staff). We evaluated the effectiveness of the Penn Resiliency Program for adolescents (PRP-A), a school-based group intervention that targets cognitive behavioral risk factors for depression. We randomly assigned 408 middle school students (ages 10-15) to one of three conditions: PRP-A, PRP-AP (in which adolescents participated in PRP-A and parents were invited to attend a parent intervention component), or a school-as-usual control. Adolescents completed measures of depression and anxiety symptoms, cognitive style, and coping at baseline, immediately after the intervention, and at 6-month follow-up. PRP-A reduced depression symptoms relative to the school as usual control. Baseline levels of hopelessness moderated intervention effects. Among participants with average and high levels of hopelessness, PRP (A and AP) significantly improved depression symptoms, anxiety symptoms, hopelessness, and active coping relative to control. Among participants with low baseline hopelessness, we found no intervention effects. PRP-AP was not more effective than PRP-A alone. We found no intervention effects on clinical levels of depression or anxiety. These findings suggest that cognitive-behavioral interventions can be beneficial when delivered by school teachers and counselors. These interventions may be most helpful to students with elevated hopelessness.

    To investigate cost-effectiveness of adolescent cognitive behavioral therapy for insomnia (CBTI) in group- and Internet-delivered formats, from a societal perspective with a time horizon of 1 y. Costs and effects data up to 1-y follow-up were obtained from a randomized controlled trial (RCT) comparing Internet CBTI to face-to-face group CBTI. The study was conducted at the laboratory of the Research Institute of Child Development and Education at the University of Amsterdam, and the academic youth mental health care center UvAMinds in Amsterdam. Sixty-two participants meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria for insomnia were randomized to face-to-face group CBTI (GT; n = 31, age = 15.6 y ± 1.8, 71.0% girls) or individual Internet CBTI (IT; n = 31, age = 15.4 y ± 1.5, 83.9% girls). The intervention consisted of six weekly sessions and a 2-mo follow up booster-session of CBTI, consisting of psychoeducation, sleep hygiene, restriction of time in bed, stimulus control, cognitive therapy, and relaxation techniques. GT sessions were held in groups of six to eight adolescents guided by two trained sleep therapists. IT consisted of individual Internet therapy with preprogrammed content similar to GT, and guided by trained sleep therapists. Outcome measures were subjective sleep efficiency (SE) ≥ 85%, and quality-adjusted life-years (QALY). Analyses were conducted from a societal perspective. Incremental cost-effectiveness ratios (ICERs) were calculated using bootstrap sampling, and presented in cost-effectiveness planes. Primary analysis showed costs over 1 y were higher for GT but effects were similar for IT and GT. Bootstrapped ICERs demonstrated there is a high probability of IT being cost-effective compared to GT. Secondary analyses confirmed robustness of results. Internet CBTI is a cost-effective treatment compared to group CBTI for adolescents, although effects were largely similar for both formats

    The study goal was to determine whether client attributes were associated with outcomes from group cognitive behavioral therapy for depression (GCBT-D) as delivered in community-based addiction treatment settings. Data from 299 depressed residential clients assigned to receive either usual care (N = 159) or usual care plus GCBT-D (N = 140) were examined. Potential moderators included gender, race/ethnicity, education, referral status, and problem substance use. Study outcomes at 6 months post-baseline included changes in depressive symptoms, mental health functioning, negative consequences from substance use, and percentage of days abstinent. Initial examination indicated that non-Hispanic Whites had significantly better outcomes than other racial/ethnic groups on two of the four outcomes. After correcting for multiple testing, none of the examined client attributes moderated the treatment effect. GCBT-D appears effective; however, the magnitude and consistency of treatment effects indicate that it may be less helpful among members of racial/ethnic minority groups and is worthy of future study.

    Social anxiety disorder (SAD) is highly prevalent and associated with a substantial societal economic burden, primarily due to high costs of productivity loss. Cognitive behavior group therapy (CBGT) is an effective treatment for SAD and the most established in clinical practice. Internet-based cognitive behavior therapy (ICBT) has demonstrated efficacy in several trials in recent years. No study has however investigated the cost-effectiveness of ICBT compared to CBGT from a societal perspective, i.e. an analysis where both direct and indirect costs are included. The aim of the present study was to investigate the cost-effectiveness of ICBT compared to CBGT from a societal perspective using a prospective design. We conducted a randomized controlled trial where participants with SAD were randomized to ICBT (n=64) or CBGT (n=62). Economic data were assessed at pre-treatment, immediately following treatment and six months after treatment. Results showed that the gross total costs were significantly reduced at six-month follow-up, compared to pre-treatment in both treatment conditions. As both treatments were equivalent in reducing social anxiety and gross total costs, ICBT was more cost-effective due to lower intervention costs. We conclude that ICBT can be more cost-effective than CBGT in the treatment of SAD and that both treatments reduce societal costs for SAD. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Logistical constraints during long-duration space expeditions will limit the ability of Earth-based mission control personnel to manage their astronaut crews and will thus increase the prevalence of autonomous operations. Despite this inevitability, little research exists regarding crew performance and psychosocial adaptation under such autonomous conditions. To this end, a newly-initiated study on crew management systems was conducted to assess crew performance effectiveness under rigid schedule-based management of crew activities by Mission Control versus more flexible, autonomous management of activities by the crews themselves. Nine volunteers formed three long-term crews and were extensively trained in a simulated planetary geological exploration task over the course of several months. Each crew then embarked on two separate 3-4 h missions in a counterbalanced sequence: Scheduled, in which the crews were directed by Mission Control according to a strict topographic and temporal region-searching sequence, and Autonomous, in which the well-trained crews received equivalent baseline support from Mission Control but were free to explore the planetary surface as they saw fit. Under the autonomous missions, performance in all three crews improved (more high-valued geologic samples were retrieved), subjective self-reports of negative emotional states decreased, unstructured debriefing logs contained fewer references to negative emotions and greater use of socially-referent language, and salivary cortisol output across the missions was attenuated. The present study provides evidence that crew autonomy may improve performance and help sustain if not enhance psychosocial adaptation and biobehavioral health. These controlled experimental data contribute to an emerging empirical database on crew autonomy which the international astronautics community may build upon for future research and ultimately draw upon when designing and managing missions.

    1999-08-01

    Much of the research that has examined the behavioral consequences of membership in mixed-gender work groups suggests that men are more participative and influential in task-related behavior. Drawing from elements of sociological, structural, and psychological perspectives, this study examined the effects of group gender composition and gender orientation of the group's task on patterns of emergent leadership behavior. Participants were assigned to male-dominated, female-dominated, or balanced-gender groups for the purpose of discussing and generating solutions for two business-related cases--each case emphasized either male-oriented or female-oriented expertise. The findings suggest that the proportional representation of men and women in a work group, along with the gender orientation of the group's task, can significantly influence the level of leadership behavior exhibited in group activity.

    Full Text Available Purpose: This study compared the effectiveness of group cognitive-behavioral therapy based on coping skills (CBT and methadone maintenance therapy (MMT in improvement of emotional regulation strategies and prevention of relapse. Method: The method of the present study was semi-experimental research design (pre-test-post-test with witness group. For sampling 45 substance abuse people who had referred to addiction treatment centers were selected and assigned to three groups of cognitive behavior therapy, methadone maintenance treatment and witness group randomly. The participants in all three groups completed the emotional intelligence questionnaire before and after the intervention. Data were analyzed by covariance method. Results: The results showed that cognitive-behavior therapy in comparison to methadone maintenance therapy and witness group led to significant improvement of emotional regulation in substance abusers, but there was no significant difference between the methadone maintenance treatment group and control group. Also, the rate of relapse in individuals who assigned to cognitive-behavior therapy group in comparison to methadone maintenance therapy and the witness group was significantly lower, but there was no significant difference between methadone therapy and witness. Conclusion: Cognitive-behavior therapy was an effective treatment that can change the cognitive and behavioral variables related to substance abuse, such as emotional regulation strategies. Thus, results suggested that drug abuse treatment programs must target these mediator variables.

    2009-01-01

    The impact of depression on cognitive behavioral group therapy (CBGT) for social phobia (SP) in a naturalistic outpatient setting was examined after treatment termination and at 1-year follow-up. Consecutive SP outpatients (N=219) were diagnosed using a structured interview. CBGT was provided in 18 1.5-hr weekly sessions. At pretreatment and posttreatment questionnaires and clinician ratings were administered. Self-report measures were obtained at 1-year follow-up. The main outcome measure was the Liebowitz Social Anxiety Scale. CBGT was found to be effective in reducing both social anxiety (effect size=1.23) as well as depression (effect size=0.94). Individuals with generalized social phobia (GSP) and individuals with specific social phobia (SSP) differed in their presenting psychopathology and in their response to CBGT. Among treatment completers, 44% GSPs and 37% SSPs achieved at least 50% improvement, and 44% GSPs and 87% SSPs reported distress and functioning within the normal range at the end of treatment. Among SPs diagnosed with major depressive disorder (MDD) at the onset of treatment, SP symptoms aggravated during the follow-up period, whereas SPs not diagnosed with MDD experienced a further alleviation of SP symptoms during follow-up. CBGT provided in a public clinic to non-selected, mostly unmedicated and comorbid patients, is an effective treatment for the majority of SP sufferers. MDD at the onset of CBGT was not associated with poorer treatment response, but predicted exacerbation of SP symptoms following treatment termination. Depressed SPs may need additional intervention to maintain CBGT gains. SSPs may benefit from less intensive CBGT than GSPs. (c) 2009 Wiley-Liss, Inc.

    Full Text Available Objective: This study was an attempt to compare the effectiveness of group cognitive-behavioral therapy and logotherapy therapy in Reducing Depression and Increasing Life Expectancy in Drug Addicts. Method: This was an experimental study along with pretest/posttest and control group. All the addicts referring to one of the methadone addiction treatment centers in Qorveh City (Naikoo Salamat Center in 2013 constituted the population of the study. Initially, 60 students were selected by simple random sampling. Then, 30 participants were randomly divided into two experimental groups and one control group based on their scores on Beck Depression Inventory and Snyder’s Life Expectancy Test. One of the experimental groups received 10 logotherapy sessions and the second experimental group received 13 sessions of group cognitive-behavioral therapy. This is so while the control group received no intervention. Results: The results showed that there was not any significant difference between group cognitive behavioral therapy and logotherapy in reducing depression. However, group cognitive behavioral therapy was found to be more effective in increased life expectancy than logotherapy. Conclusion: The results contain practical implications.

    The aim of this study was to investigate the effectiveness of the harm reduction group therapy based on Bandura's self-efficacy theory on risky behaviors of sex workers in Kerman, Iran. A quasi-experimental two-group design (a random selection with pre-test and post-test) was used. A risky behaviors questionnaire was used to collect. The sample was selected among sex workers referring to drop-in centers in Kerman. Subjects were allocated to two groups and were randomly classified into two experimental and control groups. The sample group consisted of 56 subjects. The experimental design was carried out during 12 sessions, and the post-test was performed one month and two weeks after the completion of the sessions. The results were analyzed statistically. By reducing harm based on Bandura's self-efficacy theory, the risky behaviors of the experimental group, including injection behavior, sexual behavior, violence, and damage to the skin, were significantly reduced in the pre-test compared to the post-test (P group therapy based on Bandura's self-efficacy theory can reduce the risky behaviors of sex workers.

    Full Text Available We investigate young children’s sensitivity to minimal group membership. Previous research has suggested that children do not show sensitivity to minimal cues to group membership until the age of five to six, contributing to claims that this is an important transition in the development of intergroup cognition and behavior. In this study, we investigated whether even younger children are sensitive to minimal cues to group membership. Random assignment to one of either of two color groups created a temporary, visually salient minimal group membership in 3 and 4-year-old study participants. Using explicit measures, we tested whether children preferred minimal group members when making social judgments. We find that, in the absence of any knowledge regarding the two groups, children expressed greater liking for ingroup than outgroup targets. Moreover, children estimated that ingroup members would share their preferences. Our findings demonstrate that from early in development, humans assess unknown others on the basis of minimal cues to social similarity and that the perception of group boundaries potentially underlies social assortment in strangers.

    We analyzed the effect of human visitors on the behavior of a group of spider monkeys (Ateles geoffroyi) kept on a small tourist island. Although the spider monkey is a common species in zoos, there are very few specific studies on visitor effects on these monkeys. We conducted behavioral observations on the group of spider monkeys to evaluate the effect of visitors. We also used actimetry devices to measure the variations in the spider monkeys' locomotor activity associated with human presence. With regard to the effect on behavior, we found an increase in self-directed behaviors and a decrease in vocalization, both associated with human presence. Moreover, our results suggest that when people feed monkeys, there is an increase in agonistic behaviors. On the other hand, we found that changes in activity levels in response to human presence vary among individuals. We conclude that changes in spider monkeys' behavior could provide evidence of the negative effect of visitors in our study conditions. Although we discuss the differences in activity levels due to differences in social position, further research is required this topic. Our results can be used to inform management plans for this species in captivity. Improving this relationship between humans and non-human primates through tourism education programs would benefit ecotourism and therefore species conservation programs. © 2017 Wiley Periodicals, Inc.

    2009-01-01

    Full Text Available Abstract Colloidal nanodispersions of ZnS have been prepared using aqueous micellar solution of two cationic surfactants of trimethylammonium/pyridinium series with different head groups i.e., cetyltrimethylammonium chloride (CTAC and cetyltrimethylpyridinium chloride (CPyC. The role of these surfactants in controlling size, agglomeration behavior and photophysical properties of ZnS nanoparticles has been discussed. UV–visible spectroscopy has been carried out for determination of optical band gap and size of ZnS nanoparticles. Transmission electron microscopy and dynamic light scattering were used to measure sizes and size distribution of ZnS nanoparticles. Powder X-ray analysis (Powder XRD reveals the cubic structure of nanocrystallite in powdered sample. The photoluminescence emission band exhibits red shift for ZnS nanoparticles in CTAC compared to those in CPyC. The aggregation behavior in two surfactants has been compared using turbidity measurements after redispersing the nanoparticles in water. In situ evolution and growth of ZnS nanoparticles in two different surfactants have been compared through time-dependent absorption behavior and UV irradiation studies. Electrical conductivity measurements reveal that CPyC micelles better stabilize the nanoparticles than that of CTAC.

    Obsessive-compulsive disorder (OCD) is one of the most prevalent psychiatric disorders and can cause problems for individuals in all aspects of life, including social and personal dimensions. To study the effect of group cognitive-behavioral therapy on the reduction of OCD symptoms in female participants with multiple sclerosis (MS). This double-blind randomized control trial was conducted from May 2012 to December 2014. The participants included 75 patients with MS who suffered from OCD and were referred to the Loghman Hakim and Imam Khomeini hospitals in Tehran, Iran. Thirty participants had been diagnosed through Yale-Brown Obsessive-Compulsive Symptoms (Y-BOCS). The participants were randomly divided into an experimental group (n=15) and a control group (n=15). Eleven sessions of cognitive-behavioral therapy were provided for the experimental group. Patients in the control group continued with their normal living. Hypotheses were tested using an analysis of covariance (ANCOVA). A significant reduction was found in the experimental group's obsessive-compulsive symptoms after cognitive-behavioral therapy (pcognitive-behavioral therapy could considerably reduce OCD symptoms in women with MS. The application of this method by therapists, especially Iranian clinicians, is recommended.

    We investigated factors hypothesized to moderate the effects of cognitive behavioral group-based (CB group) and bibliotherapy depression prevention programs. Using data from two trials (N = 631) wherein adolescents (M age = 15.5, 62% female, 61% Caucasian) with depressive symptoms were randomized into CB group, CB bibliotherapy, or an educational brochure control condition, we evaluated the moderating effects of individual, demographic, and environmental factors on depressive symptom reductions and major depressive disorder (MDD) onset over 2-year follow-up. CB group and bibliotherapy participants had lower depressive symptoms than controls at posttest but these effects did not persist. No MDD prevention effects were present in the merged data. Relative to controls, elevated depressive symptoms and motivation to reduce depression amplified posttest depressive symptom reduction for CB group, and elevated baseline symptoms amplified posttest symptom reduction effects of CB bibliotherapy. Conversely, elevated substance use mitigated the effectiveness of CB group relative to controls on MDD onset over follow-up. Findings suggest that both CB prevention programs are more beneficial for youth with at least moderate depressive symptoms, and that CB group is more effective for youth motivated to reduce their symptoms. Results also imply that substance use reduces the effectiveness of CB group-based depression prevention. PMID:26480199

    It is well-known that health education programs carried out in the work place are useful for employees' health promotion. However, the effectiveness of group health education programs for workers as a population approach is unclear. The purpose of this study was to examine the effectiveness of a group health education program in the workplace, and to investigate educational methods which support workers modifying their health behaviors. A total of 289 workers who received a group health education program in the manufacturing industry (mean age, 42.1 ± 11.3 years old; 175 males and 114 females) were enrolled in this study. The group health education program was carried out to educate the subjects about periodontitis, oral health actions and lifestyle behaviors to prevent oral diseases. Participants were required to fill out a self-administered questionnaire which included information about oral health knowledge, oral health actions, lifestyle behaviors and symptoms of periodontitis before, immediately after and one month after the education. We used McNemar's test for the paired comparison of questionnaire responses. The relation between acquiring knowledge about periodontitis and subjects' modification of oral health action, behavior modification and symptoms of periodontitis were examined using the chi-squared test. The relationships of knowledge retention about periodontitis, the modification of the oral health actions and lifestyle behaviors (i.e., cigarette smoking, alcohol drinking and eating between meals), were examined with participants' characteristics (i.e., age, gender and occupational category) using Fisher's exact test. Knowledge about periodontitis significantly improved immediately after receiving the health education, and this effect of education was evident one month later. However, not all of the knowledge was sufficiently retained one month after the education session. The proportion of participants undertaking desirable oral health actions

    To evaluate the effects of group counseling programs, cognitive behavioral therapy (CBT), and sports intervention on Internet addiction (IA), a systematic search in ten databases was performed to identify eligible studies without language restrictions up to January 2017. A meta-analysis and trial sequential analysis (TSA) was performed, respectively. A total of 58 randomized controlled trials (RCTs), which included 2871 participants, were incorporated into our meta-analysis. The results showed that group counseling programs, CBT, and sports intervention could significantly reduce IA levels (group counseling program: standardized mean difference (SMD), -1.37; 95% confidence interval (CI), -1.89 to -0.85; CBT: SMD, -1.88; 95% CI, -2.53 to -1.23; sports intervention: SMD, -1.70; 95% CI, -2.14 to -1.26). For group counseling programs, this treatment was more effective in four dimensions of IA, including time management, interpersonal and health issues, tolerance, and compulsive Internet use. For CBT, this treatment yielded a positive change in depression, anxiousness, aggressiveness, somatization, social insecurity, phobic anxiety, paranoid ideation, and psychoticism. For sports intervention, the significant effects were also observed in all dimensions of the IA scale. Each of group counseling programs, cognitive behavioral therapy, and sports intervention had a significant effect on IA and psychopathological symptoms. Sports intervention could improve withdrawal symptoms especially.

    To determine the effect of age at grouping on behavior, health, and production of dairy bull calves, 90 Holstein-Friesian bull calves were housed in individual pens until moved to 1 of 3 treatments. Calves were housed in groups of 3 calves at 3 d old (GH3), 7 d old (GH7), or 14 d old (GH14) until 7 wk of age. Ten groups of 3 calves for each treatment were used, with 5 pens/treatment in each of 2 replications (10 pens/treatment, 3 treatments, 3 calves/treatment; 90 calves total). Direct behavioral observations using instantaneous scan sampling every 10 min were conducted twice per week for 7 wk. At the same times, video data were recorded for continuous observations at feeding time to observe the overall activity of group-housed calves. Hip height, heart girth, and health scores were recorded weekly and body weight was recorded at the start and end of the study. Calves in GH3 spent more time playing and but more time cross-sucking and displacing other calves from milk bottles. Calves engaged in social interaction as early as 3 d of age, and social interactions between 3 to 6 wk of age increased markedly. Calves housed in GH14 vocalized more than did calves in GH7 and GH3. No difference was found between treatments in growth performance. Calf fecal, cough, and nasal and ocular discharge scores, differential leukocyte counts, and plasma cortisol concentrations were not affected by age at grouping. However, during the first week of grouping, when calves were moved from individual pens to group pens, some calves were unable to find their milk bottles and required guidance. In conclusion, these data show no adverse effects on health or performance and some benefits on social behavior for early (d 3) grouping of calves.

    It is well known that the differences-in-differences (DD) estimator is based on the assumption that in the absence of treatment, the average outcomes for the treated group and the control group will follow a common trend over time. That can be problematic, especially when the selection for the treatment is influenced by the individual's unobserved behavior correlating with the medical utilization. The aim of this study was to develop an index for controlling a patient's unobserved heterogeneous response to reform, in order to improve the comparability of treatment assignment. This study showed that a DD estimator of the reform effects can be decomposed into effects induced by moral hazard and by changes in health risk within the same treated/untreated group. This article also presented evidence that the constructed index of the price elasticity of the adjusted clinical group has good statistical properties for identifying the impact of reform. © The Author(s) 2012.

    Internalizing and externalizing problems differ by musical tastes. A high school-based sample of 4159 adolescents, representative of Dutch youth aged 12 to 16, reported on their personal and social characteristics, music preferences and social-psychological functioning, measured with the Youth Self-Report (YSR). Cluster analysis on their music preferences revealed six taste groups: Middle-of-the-road (MOR) listeners, Urban fans, Exclusive Rock fans, Rock-Pop fans, Elitists, and Omnivores. A seventh group of musically Low-Involved youth was added. Multivariate analyses revealed that when gender, age, parenting, school, and peer variables were controlled, Omnivores and fans within the Exclusive Rock groups showed relatively high scores on internalizing YSR measures, and social, thought and attention problems. Omnivores, Exclusive Rock, Rock-Pop and Urban fans reported more externalizing problem behavior. Belonging to the MOR group that highly appreciates the most popular, chart-based pop music appears to buffer problem behavior. Music taste group membership uniquely explains variance in both internalizing and externalizing problem behavior.

    Full Text Available We analyze two large datasets from technological networks with location and social data: user location records from an online location-based social networking service, and anonymized telecommunications data from a European cellphone operator, in order to investigate the differences between individual and group behavior with respect to physical location. We discover agreements between the two datasets: firstly, that individuals are more likely to meet with one friend at a place they have not visited before, but tend to meet at familiar locations when with a larger group. We also find that groups of individuals are more likely to meet at places that their other friends have visited, and that the type of a place strongly affects the propensity for groups to meet there. These differences between group and solo mobility has potential technological applications, for example, in venue recommendation in location-based social networks.

    We sought to test the efficacy of an intervention that was designed to promote social inclusion and commitment to education, in reducing among students health risk behaviors and improving emotional well-being. The design was a cluster-randomized trial in 25 secondary schools in Victoria, Australia. The subjects were 8th-grade students (aged 13 to 14 y) in 1997 (n=2545) and subsequent 8th-grade students in 1999 (n=2586) and 2001 (n=2463). The main outcomes were recent substance use, antisocial behavior, initiation of sexual intercourse, and depressive symptoms. At 4-year follow-up, the prevalence of marked health risk behaviors was approximately 20% in schools in the comparison group and 15% in schools in the intervention group, an overall reduction of 25%. In ordinal logistic regression models a protective effect of intervention was found for a composite measure of health risk behaviors in unadjusted models (odds ratio [OR]= 0.69; 95% confidence interval [CI]= 0.50, 0.95) and adjusted models (OR= 0.71; CI =0.52, 0.97) for potential confounders. There was no evidence of a reduction in depressive symptoms. The study provides support for prevention strategies in schools that move beyond health education to promoting positive social environments.

    Computer-based educational games present an opportunity for health education in school; however, their feasibility in school settings and effectiveness in changing behavior are poorly understood. To evaluate the feasibility, acceptability, and effects of the Quest to Lava Mountain (QTLM) computer game on dietary behaviors, physical activity behaviors, and psychosocial factors among ethnically diverse children in Texas. Quasi-experimental group-randomized controlled trial conducted during the 2012-2013 school year. A total of 107 children in fourth and fifth grade consented. There was an attrition rate of 8.8% with a final sample size of 44 children in three intervention schools, and a sample of 50 children in three comparison schools. Dietary intake was measured using two random 24-hour recalls, whereas child self-report surveys measured diet, physical activity, and psychosocial factors before and after the intervention. Process data on QTLM usability and back-end server data on QTLM exposure and progress achieved were collected. QTLM was implemented as part of the in-school or afterschool program. Recommended game exposure duration was 90 min/wk for 6 weeks. Analysis of covariance or logistic regression models evaluated effects of QTLM on diet, physical activity, and psychosocial factors. Post hoc exploratory analysis examined the changes before and after the intervention in outcome variables among children in the intervention group. Significance was set at Peffects of QTLM on physical activity. However, post hoc analysis showed that higher QTLM exposure and gaming progress was associated with increased frequency of physical activity (Peffects on diet and physical activity behaviors among children in elementary school.

    Full Text Available Background: In the empirical and clinical literature, complex posttraumatic stress disorder (PTSD and personality disorders (PDs are suggested to be predictive of drop-out or reduced treatment effectiveness in trauma-focused PTSD treatment. Objective: In this study, we aimed to investigate if personality characteristics would predict treatment compliance and effectiveness in stabilizing complex PTSD treatment. Method: In a randomized controlled trial on a 20-week stabilizing group cognitive behavioral treatment (CBT for child-abuse-related complex PTSD, we included 71 patients of whom 38 were randomized to a psycho-educational and cognitive behavioral stabilizing group treatment. We compared the patients with few PD symptoms (adaptive (N=14 with the non-adaptive patients (N=24 as revealed by a cluster analysis. Results: We found that non-adaptive patients compared to the adaptive patients showed very low drop-out rates. Both non-adaptive patients, classified with highly different personality profiles “withdrawn” and “aggressive,” were equally compliant. With regard to symptom reduction, we found no significant differences between subtypes. Post-hoc, patients with a PD showed lower drop-out rates and higher effect sizes in terms of complex PTSD severity, especially on domains that affect regulation and interpersonal problems. Conclusion: Contrary to our expectations, these preliminary findings indicate that this treatment is well tolerated by patients with a variety of personality pathology. Larger sample sizes are needed to study effectiveness for subgroups of complex PTSD patients.

    We aimed to evaluate the potential effect of age on the natural behavior of bladder cancer and to compare these findings between different age groups. The clinical and pathologic data of 239 patients treated at our institution between 1994 and 2014 were analyzed. The patients were classified into three groups according to age: ≤ 40 years (Group 1), 41-59 years (Group 2), and ≥ 60 years (Group 3). The following data were collected: characteristics of the patients, initial pathological findings after transurethral resection, tumor stage and grade, tumor size and multiplicity, and disease recurrence and progression. The mean age of the patients at initial diagnosis was 34.2±5.5 years, 53±5.1 years, and 71.1±7 years in Groups 1, 2, and 3, respectively. There were 207 (86.6%) patients with nonmuscle-invasive urothelial bladder cancer and 32 (13.4%) patients with muscle-invasive disease. Tumor recurrence was significantly lower in Group 1 than in Group 2 (p=0.001) and Group 3 (p=0.001). Although the time to tumor recurrence was significantly different between the three groups (p=0.001), no significant difference was noted in the time to progression (p=0.349). Patients with urothelial cancer younger than 40 years tend to have single and small tumors. The tumor recurrence rate is lower in the younger age group, but tumor progression is similar in older and younger patients. Therefore, the findings indicate that clinicians should be careful when assessing the invasiveness of urothelial tumors in younger patients and start treatment as soon as possible. Copyright © 2016.

    2016-10-01

    The aim of this study was to examine over a 12-month post-intervention period whether the participation of community-living individuals with mental illness in cognitive behavioral group therapy for recovery of self-esteem (CBGTRS) resulted in improved outcomes. This was a non-randomized controlled trial. The participants were persons with mental illness who resided in communities in the Chugoku region of Japan. In total, 41 were assigned to an experimental group (CBGTRS intervention, 12 group sessions), and 21 to a control group. Outcome indices (self-esteem, moods, cognition, subjective well-being, psychiatric symptoms) were measured for the experimental group prior to intervention (T0), immediately post-intervention (T1), and at 3 (T2) and 12 (T3) months post-intervention. The control group was measured at the same intervals. For the experimental group, self-esteem scores at T1, T2, and T3 were significantly higher than at T0. Moods and cognition scores remained significantly low until T2. Scores for Inadequate Mental Mastery in the subjective well-being index had not decreased by T3. Confidence in Coping remained significantly high until T2. Psychiatric symptoms scores at T0, T1, T2, and T3 were significantly lower than at T0. The means and standard errors for self-esteem and Inadequate Mental Mastery increased until T3, and those for Tension-Anxiety, Depression-Dejection, and Confusion decreased until T2. From within-group trends and between-group differences in self-esteem, we conclude that CBGTRS may have a relatively long-term effect on self-esteem recovery. T2 is the turning point for moods and cognition; thus, follow-up is needed 3 months following the initial program. © 2016 The Authors.

    2016-04-01

    Conclusion: Based on the results, the group cognitive-behavioral therapy can increase the use of compatible strategies for coping with stress and decrease the use of incompatible strategies. This issue is related to factors such as complete understanding of Alzheimer’s disease and its effects, creating an atmosphere for presentation and an opportunity for social interaction, understanding the importance of sport and allocating time for recreational activities, learning body relaxation in stressful situations, understanding life problems, solving problem techniques, feeling of control, and time management. Thus, we recommend using group cognitivebehavioral therapy as a low-cost treatment for family caregivers of patients with Alzheimer’s and patients with chronic diseases.

    The aim of the current study was to evaluate whether cognitive behavioral group therapy has a positive impact on psychiatric, and motor and non-motor symptoms in Parkinson's disease (PD). We assigned 20 PD patients with a diagnosis of psychiatric disorder to either a 12-week cognitive behavioral therapy (CBT) group or a psychoeducational protocol. For the neurological examination, we administered the Unified Parkinson's Disease Rating Scale and the non-motor symptoms scale. The severity of psychiatric symptoms was assessed by means of the Hamilton Depression Rating Scale, the Hamilton Anxiety Rating Scale, the Brief Psychiatric Rating Scale, and the Clinical Global Impressions. Cognitive behavioral group therapy was effective in treating depression and anxiety symptoms as well as reducing the severity of non-motor symptoms in PD patients; whereas, no changes were observed in PD patients treated with the psychoeducational protocol. CBT offered in a group format should be considered in addition to standard drug therapy in PD patients.

  5. Racial differences in sensitivity to behavioral integrity: attitudinal consequences, in-group effects, and "trickle down" among Black and non-Black employees.

    Science.gov (United States)

    2007-05-01

    Recent research has suggested that employees are highly affected by perceptions of their managers' pattern of word-action consistency, which T. Simons (2002) called behavioral integrity (BI). The authors of the present study suggest that some employee racial groups may be more attentive to BI than others. They tested this notion using data from 1,944 employees working at 107 different hotels and found that Black employees rated their managers as demonstrating lower BI than did non-Black employees. Mediation analyses were consistent with the notion that these differences in perceived BI in turn account for cross-race differences in trust in management, interpersonal justice, commitment, satisfaction, and intent to stay. Results of hierarchical linear modeling were consistent with the idea that middle managers' perceptions of their senior managers' BI "trickle down" to affect line employee perceptions of the middle managers and that this trickle-down effect is stronger for Black employees. The authors interpret these results as indicative of heightened sensitivity to managers' BI on the part of Black employees. They also found a reverse in-group effect, in that Black employees were substantially more critical of Black managers than were non-Black employees. 2007 APA, all rights reserved

  6. The effectiveness of a training for patients with unexplained physical symptoms: protocol of a cognitive behavioral group training and randomized controlled trial

    2009-07-01

    Full Text Available Abstract Background In primary care, up to 74% of physical symptoms is classified as unexplained. These symptoms can cause high levels of distress and healthcare utilization. Cognitive behavioral therapy has shown to be effective, but does not seem to be attractive to patients. An exception herein is a therapy based on the consequences model, which distinguishes itself by its labeling of psychosocial distress in terms of consequences rather than as causes of physical symptoms. In secondary care, 81% of the patients accepts this therapy, but in primary care the outcome is poor. We assume that positive outcome can also be reached in primary care, when the consequences model is modified and used bottom-up in an easily accessible group training, in which patients are relieved of being blamed for their symptoms. Our aim is to investigate the (cost-effectiveness of this training. Methods and design A randomized controlled trial is designed. One hundred patients are randomized to either the group training or the waiting list. Physicians in general practices and outpatients clinics of general hospitals refer patients. Referral leads to inclusion if patients are between 18 and 65 years old, understand Dutch, have no handicaps impeding participation and the principal DSM-IV-TR classification is undifferentiated somatoform disorder or chronic pain disorder. In contrast to other treatment effect studies, the co-morbidity of a personality disorder does not lead to exclusion. By this, we optimize the comparability between the study population and patients in daily practice enlarging the generalization possibilities. Also in contrast to other effect studies, we chose quality of life (SF-36 instead of physical symptoms as the primary outcome measure. The SF-6D is used to estimate Quality Adjusted Life Years (QALYs. Costs are measured with the Trimbos/iMTA Questionnaire for Costs associated with Psychiatric Illness. Measurements are scheduled at baseline, after

    To assess the cost-effectiveness of group cognitive behavior therapy (gCBT) in comparison with routine primary care for women with postnatal depression in the UK. Our analysis was based on a systematic literature review of the relative clinical effectiveness of gCBT compared with routine primary care and further reviews, supplemented with expert opinion of the likely cost of providing gCBT and the duration of comparative advantage for gCBT. Raw data were used to estimate a statistical relationship between changes in the Edinburgh Postnatal Depression Score (EPDS) values and changes in short-form six dimensions' (SF-6D) values. A mathematical model was constructed, and probabilistic sensitivity analyses were undertaken to estimate the mean cost per quality-adjusted life-year (QALY) and to evaluate the expected value of perfect information (EVPI). The mean cost per QALY from the stochastic analysis was estimated to be pound36,062; however, there was considerable uncertainty around this value. The EVPI was estimated to be greater than pound64 million; the key uncertainties were in the cost per woman of providing treatment and in the statistical relationship between changes in EPDS values and changes in SF-6D values. The expected value of perfect partial information for both of these parameters was in excess of pound25 million. Given the current information, the use of gCBT does not appear to be cost-effective; however, this decision is uncertain. The value of information analyses conducted indicates that further research to provide robust information on key parameters is needed and appears justified in cost-effective terms.

    Behavioral science has long played a central role in pediatric oncology clinical service and research. Early work focused on symptom relief related to side effects of chemotherapy and pain management related to invasive medical procedures. As survival rates improved, the focused has shifted to examination of the psychosocial impact, during and after treatment, of pediatric cancer and its treatment on children and their families. The success of the clinical trials networks related to survivorship highlights an even more critical role in numerous domains of psychosocial research and care. Within the cooperative group setting, the field of behavioral science includes psychologists, social workers, physicians, nurses, and parent advisors. The research agenda of this group of experts needs to focus on utilization of psychometrically robust measures to evaluate the impact of treatment on children with cancer and their families during and after treatment ends. Over the next 5 years, the field of behavioral science will need to develop and implement initiatives to expand use of standardized neurocognitive and behavior batteries; increase assessment of neurocognition using technology; early identification of at-risk children/families; establish standards for evidence-based psychosocial care; and leverage linkages with the broader behavioral health pediatric oncology community to translate empirically supported research clinical trials care to practice.

    The present research examines the influence of implicit and explicit personality characteristics on group process and effectiveness. Individuals from 112 groups participated in 2 problem-solving tasks and completed measures of group process and effectiveness. Results indicated that groups characterized by higher levels of psychopathy and implicit aggression tended to have more dysfunctional interactions and negative perceptions of the group. In addition, task participation and negative socioemotional behaviors fully mediated the relationship between group personality traits and group commitment and cohesion, and negative socioemotional behaviors fully mediated the relationship between group personality and performance on both tasks. Implications of antisocial traits for group interactions and performance, as well as for future theory and research, are discussed. PsycINFO Database Record (c) 2014 APA, all rights reserved

    Jones, M. Gail; Carter, Glenda

    In this study we describe the social interactions of ability-grouped dyads as they constructed knowledge of balance concepts to elucidate the relationship between interactions and conceptual growth. The verbal and nonverbal behaviors of 30 fifth-grade students were recorded as they completed three activities related to balance. These student interactions were examined within a framework of social cognition. For each dyad, characteristics of ability-grouped dyads were identified. Results revealed that high-achieving students effectively used prior experiences, maintained focus on the learning task, and were able to manipulate the equipment effectively to construct knowledge. Low-achieving students exhibited off-task behavior, lacked a metacognitive framework for organizing the learning tasks, centered on irrelevant features of the equipment, and were unable to use language effectively to mediate learning. Within low-high student dyads, high-achieving students typically modeled thinking processes and strategies for manipulating equipment. In addition, they focused the low-achieving students on the components of the tasks while verbally monitoring their progress, thus enabling low students to identify the critical features necessary for concept construction. These results highlighted the differences that students have in the use of language and tools. Low students' inefficient use of tools has implications for the ways science teachers structure lessons and group students for laboratory work.Received: 8 March 1993; Revised: 6 January 1994;

    Dominance in the peer group is important for adolescents. Resource Control Theory posits that both coercive and prosocial (positively assertive) strategies are associated with dominance. Combining Resource Control Theory with Socioanalytic Theory on personality, we hypothesized that inspiring group members would be an additional effective strategy. This study examined whether the three behavioral strategies and two types of social skills (social competence and manipulation) predicted dominance (resource control and popularity). Participants were 619 Dutch adolescents (M age  = 13.1; 47% female) in the first grade of secondary school. They completed peer reports (behavioral strategies and dominance) and self-reports (social skills). Only inspirational and coercive strategies substantially predicted dominance. Main effects of social skills emerged. Moderation between strategies and social skills was only observed for girls (e.g., coercive strategy use was associated with more popularity for girls with higher levels of social manipulation skills). This study furthered our understanding of the predictors of dominance in adolescence by including inspirational behavior and examining prosocial and antisocial skills.

    2015-07-01

    This article reports an investigation into how individuals form perceptions of overall voice behavior in group contexts. More specifically, the authors examine the effect of the proportion of group members exhibiting voice behavior in the group, the frequency of voice events in the group, and the measurement item referent (group vs. individual) on an individual's ratings of group voice behavior. In addition, the authors examine the effect that measurement item referent has on the magnitude of the relationship observed between an individual's ratings of group voice behavior and perceptions of group performance. Consistent with hypotheses, the results from 1 field study (N = 220) and 1 laboratory experiment (N = 366) indicate that: (a) When group referents were used, raters relied on the frequency of voice events (and not the proportion of group members exhibiting voice) to inform their ratings of voice behavior, whereas the opposite was true when individual-referent items were used, and (b) the magnitude of the relationship between observers' ratings of group voice behavior and their perceptions of group performance was higher when raters used group-referent, as opposed to an individual-referent, items. The authors discuss the implications of their findings for scholars interested in studying behavioral phenomena occurring in teams, groups, and work units in organizational behavior research.

  19. Identifying Differences in Cultural Behavior in Online Groups

    Energy Technology Data Exchange (ETDEWEB)

    Gregory, Michelle L.; Engel, David W.; Bell, Eric B.; Mcgrath, Liam R.

    2012-07-23

    We have developed methods to identify online communities, or groups, using a combination of structural information variables and content information variables from weblog posts and their comments to build a characteristic footprint for groups. We have worked with both explicitly connected groups and 'abstract' groups, in which the connection between individuals is in interest (as determined by content based features) and behavior (metadata based features) as opposed to explicit links. We find that these variables do a good job at identifying groups, placing members within a group, and helping determine the appropriate granularity for group boundaries. The group footprint can then be used to identify differences between the online groups. In the work described here we are interested in determining how an individual's online behavior is influenced by their membership in more than one group. For example, individuals belong to a certain culture; they may belong as well to a demographic group, and other 'chosen' groups such as churches or clubs. There is a plethora of evidence surrounding the culturally sensitive adoption, use, and behavior on the Internet. In this work we begin to investigate how culturally defined internet behaviors may influence behaviors of subgroups. We do this through a series of experiments in which we analyze the interaction between culturally defined behaviors and the behaviors of the subgroups. Our goal is to (a) identify if our features can capture cultural distinctions in internet use, and (b) determine what kinds of interaction there are between levels and types of groups.

    Adams, Jeffrey P.; Brissenden, Gina; Lindell, Rebecca S.; Slater, Timothy F.; Wallace, Joy

    In an effort to determine how our students were responding to the use of collaborative learning groups in our large enrollment introductory astronomy (ASTRO 101) courses, we systematically observed the behavior of 270 undergraduate students working in 48 self-formed groups. Their observed behaviors were classified as: (i) actively engaged; (ii) watching actively; (iii) watching passively; and (iv) disengaged. We found that male behavior is consistent regardless of the sex-composition of the groups. However, females were categorized as watching passively and or disengaged significantly more frequently when working in groups that contained uneven numbers of males and females.

    The theory of rational-emotive therapy (RET) and of cognitive-behavioral therapy (CBT) is briefly explained and is applied to group therapy. It is shown how RET and CBT therapy groups deal with transference, countertransference, levels of group intervention, process versus content orientation, identifying underlying group process themes, here-and-now activation, working with difficult group members, activity levels of therapist and group members, and other group problems. Although they particularly concentrate on people's tendencies to construct and create their own "emotional" difficulties, RET and CBT group procedures fully acknowledge the interactions of human thoughts, feelings, and actions and active-directively employ a variety of cognitive, emotive, and behavioral group therapy techniques.

    Sexuality usually decreases during pregnancy. To evaluate sexual behavior during pregnancy, comparing two groups. One had sexual education and the other had none. After randomizing two groups of pregnant women, they completed self-administered questionnaires regarding attitudes and sexual behavior before and during pregnancy. Sexual education was provided in one group and a second self-administered questionnaire was completed 12 weeks later. Responses were summarized using descriptive statistics. Comparison of change of sexual behavior between two groups was analyzed using chi-square and student t-tests. The change in frequency of coitus during pregnancy was compared between the sexual education group and the noneducation group. There was no statistically difference in changes of sexual behavior between the two groups. There was a reduction in frequency of coitus (90.6% vs. 94.9%, P>0.05) between the nonsexual education group and the sexual education group and no statistically significant change in mean reduction of sexual desire (8.9 vs. 4.4, P>0.05), sexual arousal (14.3 vs. 13.1, P>0.05), satisfaction from coitus (15.4 vs. 7.2, P>0.05), and orgasm from coitus (12.3 vs. 12.3, P>0.05). The change of sexual behavior during pregnancy in the sexual education group was not different from that in the nonsexual education group. © 2010 International Society for Sexual Medicine.

    Parents play an important role in development and continuation of anxiety disorders in children. Yet the evidence on parent contribution in cognitive behavioral therapy (CBT) for childhood anxiety is limited. This open randomized trial examined the effectiveness of a parent-directed group CBT to manage children with anxiety disorders. Parents of 42 children aged 6-12 with primary anxiety disorders were allocated to a six, two-hour weekly intervention and a wait-list (WL) control. The Revised Children's Manifest Anxiety, Children's Depression Inventory, Strengths and Difficulties Questionnaire-Home Version, Depression-Anxiety-Stress Scale, Children Global Assessment Scale, and Global Relational Assessment of Functioning were used to assess children's and parents' functioning and emotional symptoms. Parents completed consumer satisfaction questionnaire. Parents in the CBT group reported significant improvement in their depressive symptoms (p=0.006) and the family functioning (p=0.04), as well as reduction in children's emotional symptoms (p=0.007). Clinician rating of children's functioning showed significant improvement in the CBT group(p=0.001). There was no significant difference in children rating of their anxiety within groups from pre- to post-intervention. Parents were satisfied mostly with the intervention. A brief parent-only CBT based intervention can be effective in the management of childhood anxiety.

    There is growing evidence that the capacity for emotion regulation is compromised in individuals with bipolar disorder. Dialectical behavior therapy (DBT), an empirically supported treatment that specifically targets emotion dysregulation, may be an effective adjunct treatment for improving emotion regulation and residual mood symptoms in patients with bipolar disorder. In this open, proof-of-concept pilot study, 37 participants engaged in a 12-week DBT group skills training program, learning mindfulness, emotion regulation, and distress tolerance skills. Repeated measures mixed models revealed skill acquisition in the areas of mindfulness, emotion regulation and distress tolerance, as well as improved psychological well-being and decreased emotion reactivity. The results of this study support a burgeoning literature that DBT is a feasible adjunct intervention for patients with bipolar disorder. Copyright © 2017. Published by Elsevier Ltd.

    Highlights: • Small groups are modeled on interconnected networks. • Players face different dilemmas inside and outside small groups. • Impact of the ratio and strength of link on the behavioral evolution are studied. - Abstract: Understanding the behavioral evolution in evacuation is significant for guiding and controlling the evacuation process. Based on the fact that the population consists of many small groups, here we model the small groups which are separated in space but linked by other methods, such as kinship, on interconnected networks. Namely, the players in the same layer belong to an identical small group, while the players located in different layers belong to different small groups. And the players of different layers establish interaction by edge crossed layers. In addition, players face different dilemmas inside and outside small groups, in detail, the players in the same layer play prisoner’s dilemma, but players in different layers play harmony game. By means of numerous simulations, we study the impact of the ratio and strength of link on the behavioral evolution. Because the framework of this work takes the space distribution into account, which is close to the realistic life, we hope that it can provide a new insight to reveal the law of behavioral evolution of evacuation population.

  11. Critical behavior of two- and three-dimensional ferromagnetic and antiferromagnetic spin-ice systems using the effective-field renormalization group technique

    Garcia-Adeva, Angel J.; Huber, David L.

    2001-07-01

    In this work we generalize and subsequently apply the effective-field renormalization-group (EFRG) technique to the problem of ferro- and antiferromagnetically coupled Ising spins with local anisotropy axes in geometrically frustrated geometries (kagomé and pyrochlore lattices). In this framework, we calculate the various ground states of these systems and the corresponding critical points. Excellent agreement is found with exact and Monte Carlo results. The effects of frustration are discussed. As pointed out by other authors, it turns out that the spin-ice model can be exactly mapped to the standard Ising model, but with effective interactions of the opposite sign to those in the original Hamiltonian. Therefore, the ferromagnetic spin ice is frustrated and does not order. Antiferromagnetic spin ice (in both two and three dimensions) is found to undergo a transition to a long-range-ordered state. The thermal and magnetic critical exponents for this transition are calculated. It is found that the thermal exponent is that of the Ising universality class, whereas the magnetic critical exponent is different, as expected from the fact that the Zeeman term has a different symmetry in these systems. In addition, the recently introduced generalized constant coupling method is also applied to the calculation of the critical points and ground-state configurations. Again, a very good agreement is found with exact, Monte Carlo, and renormalization-group calculations for the critical points. Incidentally, we show that the generalized constant coupling approach can be regarded as the lowest-order limit of the EFRG technique, in which correlations outside a frustrated unit are neglected, and scaling is substituted by strict equality of the thermodynamic quantities.

    Adolescents' social cognitive understanding of their social world is often inaccurate and biased. Focusing on peer groups, this study examines how adolescents' psychological, behavioral, and relational characteristics influence the extent to which they accurately identify their own and others' peer groups. Analyses were conducted with a sample of 1481 seventh- and tenth-grade Chinese students who are embedded with 346 peer groups. Overall, females and older students had more accurate perceptions. In addition, lower self-esteem, higher indegree centrality, and lower betweenness centrality in the friendship network predicted more accurate perception of one's own groups, whereas higher academic performance and lower betweenness centrality in the friendship network predicted more accurate perception of others' groups. Implications for understanding the connection between adolescents' psychological and behavioral traits, social relationships, and social cognition are discussed. Copyright © 2016 Elsevier Inc.

    Despite the widespread interest in the topic of organizational citizenship behaviors (OCBs), little empirical research has tested the fundamental assumption that these forms of behavior improve the effectiveness of work groups or organizations in which they are exhibited. In the present study, the effects of OCBs on the quantity and quality of the performance of 218 people working in 40 machine crews in a paper mill located in the Northeastern United States were examined. The results indicate that helping behavior and sportsmanship had significant effects on performance quantity and that helping behavior had a significant impact on performance quality. However, civic virtue had no effect on either performance measure.

    Organisms rarely act in isolation. Their decisions and movements are often heavily influenced by direct and indirect interactions with conspecifics. For example, we each represent a single node within a social network of family and friends, and an even larger network of strangers. This group membership can affect our opinions and actions. Similarly, when in a crowd, we often coordinate our movements with others like fish in a school, or birds in a flock. Contributions of the group to individual behaviors are observed across a wide variety of taxa but their biological mechanisms remain largely unknown. With the advent of powerful computational tools as well as the unparalleled genetic accessibility and surprisingly rich social life of Drosophila melanogaster, researchers now have a unique opportunity to investigate molecular and neuronal determinants of group behavior. Conserved mechanisms and/or selective pressures in D. melanogaster can likely inform a much wider phylogenetic scale. Here, we highlight two examples to illustrate how quantitative and genetic tools can be combined to uncover mechanisms of two group behaviors in D. melanogaster: social network formation and collective behavior. Lastly, we discuss future challenges towards a full understanding how coordinated brain activity across many individuals gives rise to the behavioral patterns of animal societies. © 2017.

    We investigate the prediction of the future prices from the structures and the networks of the companies in special financial groups. After the financial group network has been constructed from the value of the high cross-correlation, each company in a group is simulated and analyzed how it buys or sells stock is anaylzed and how it makes rational investments is forecasted. In the shortmemory behavior rather than the long-memory behavior, each company among a group can make a rational investment decision by using a stochastic evolution rule in the financial network. In particular, we simulate and analyze the investment situation in connection with the empirical data and the simulated result.

    Less than half of all U.S. adults meet the 2008 Physical Activity Guidelines. Leader behaviors and group cohesion have been associated with increased participation or adherence in sports team and exercise class settings. Physical activity interventions in community settings that encompass these factors may enhance intervention adherence. The purpose of this study is to examine the impact of Community Health Promoter leader behaviors and group cohesion on participation in a walking group intervention among racially/ethnically diverse adults in low to moderate-income communities in Detroit, Michigan. Data for the current study were drawn from the Walk Your Heart to Health (WYHH) data set. WYHH was a multisite cluster RCT with a lagged intervention and outcome measurements at baseline and 4, 8, and 32 weeks. Pooled survey data from both intervention arms were used for the current study. Data were analyzed between August 2013 and October 2014. A total of 603 non-Hispanic black, non-Hispanic white, and Hispanic adults across five cohorts that began the 32-week WYHH intervention between March 2009 and October 2011. The intervention was a 32-week walking group program hosted by community- and faith-based organizations and facilitated by Community Health Promoters. Walking groups met three times per week for 90 minutes per session. To promote participation in or adherence to WYHH, Community Health Promoters used evidence-based strategies to facilitate group cohesion. Group members assumed increasing leadership responsibility for facilitating sessions over time. Participation in WYHH as measured by consistency of attendance. Community Health Promoter leader behaviors were positively associated with participation in WYHH. Social but not task cohesion was significantly associated with consistent participation. Social cohesion may mediate the relationship between leader behaviors and walking group participation. Providing leaders with training to build socially cohesive groups

    2014-06-01

    The increasing use of online collaboration and information sharing in the last decade has resulted in explosion of criminal and anti-social activities in online communities. Detection of such behaviors are of interest to commercial enterprises who want to guard themselves from cyber criminals, and the military intelligence analysts who desire to detect and counteract cyberwars waged by adversarial states and organizations. The most challenging behaviors to detect are those involving multiple individuals who share actions and roles in the hostile activities and individually appear benign. To detect these behaviors, the theories of group behaviors and interactions must be developed. In this paper we describe our exploration of the data from collaborative social platform to categorize the behaviors of multiple individuals. We applied graph matching algorithms to explore consistent social interactions. Our research led us to a conclusion that complex collaborative behaviors can be modeled and detected using a concept of group behavior grammars, in a manner analogous to natural language processing. These grammars capture constraints on how people take on roles in virtual environments, form groups, and interact over time, providing the building blocks for scalable and accurate multi-entity interaction analysis and social behavior hypothesis testing.

    The anionic block copolymerization of 4,4' -vinylphenyl-N,N-bis(4-tert-butylphenyl)benzenamine (A) with furfuryl isocyanate (B) was carried out using potassium naphthalenide (K-Naph) in tetrahydrofuran at -78 and -98 °C to prepare well-defined block copolymers containing furan groups for the formation of thermoreversible networks via a Diels Alder (DA) reaction. While no block copolymerization was observed in the absence of sodium tetraphenylborate (NaBPh4) due to side reactions, well-defined poly-(B-b-A-b-B) (PBAB) copolymers with controlled molecular weights (Mn = 18 700 19 500 g mol -1) and narrow molecular weight distributions (Mw/Mn = 1.08 -1.17) were successfully synthesized in the presence of excess NaBPh4. We prevented the occurrence of the undesirable side reactions during polymerization of B of NaBPh4, which results in the change in the countercation from K+ to Na+ for further polymerization of B. Moreover, the cross-linking via the DA reaction between the furan groups of PBAB and bismaleimide was proved by FT-IR and differential scanning calorimetry (DSC), and the thermoreversible properties of the cross-linked polymer were subsequently investigated using DSC and solubility testing.

    Full Text Available Background. Periodontal disease is considered as a risk factor for poor pregnancy outcomes, including preterm birth and low birth weight. Only few studies have assessed the knowledge and practice behaviours of healthcare providers, concerning oral health during pregnancy, periodontal diseases and their role in adverse pregnancy outcomes. The present study aimed to compare the knowledge and practice behaviours of a group of Iranian obstetricians, general practitioners, and midwives about periodontal disease.Design and methods. A cross-sectional study was conducted using a self-administered, structured questionnaire that was previously used in North Carolina. The questionnaire was translated into Persian language and was randomly distributed among 200 obstetricians, general practitioners, and midwives participating in an international congress. Data were analysed by Chi-square and spearman correlation tests using SPSS statistical software (version PASW 18.Results. A total of 150 completed the questionnaires, achieving a response rate of 75%. Totally, the knowledge of the obstetricians was more accurate compared to the two other groups and the midwives were the worst. More experienced general practitioners (P=0.002 and obstetricians (P=0.049 did less dental examinations for their patients during their first visit or periodically. More experienced obstetricians also referred their patients for dental examinations during pregnancy less than their less experienced colleagues (P<0.001.Conclusions. Although the participants had some knowledge about periodontal disease and its association with adverse pregnancy outcomes, there is much space for improvements. The participants’ attitude and knowledge were consistent.

    2016-09-01

    Full Text Available The way consumers think about the products they will buy determines their buying behavior. The decision to buy a particular product is obviously in accordance with the buyer’s attitude. The buyers will also feel more comfortable if their behavior meets with the approval and expectations of the people close to them. While the development of a certain attitude has no effect on subjective judgment, the effect of compromise is likely to make a contribution to its development. Since it is still unclear, this study’s main purposed is to clarify this. In addition, while an attitude is theorized as being a predictor of behavior, through behavioral intention, the study’s secondary purpose is to boost the earlier findings. Likewise, in accordance with the theory of planned behavior, the study will also examine the other predictors of behavioral intention, in relation to the behavioral intention itself. A sample consisting of a 100 respondents was compiled by using the convenience and judgment technique. The data were analyzed using Amos 16.0 and SPSS 16.0. As expected, the compromise effect had a significant influence on whether the customers’ attitude or the subjective norm was the main determinant. Likewise, the customers’ attitude, the subjective norm and perceived behavioral control were confirmed as good predictors of customers’ behavioral intentions.

  15. Effective strategies for behavior change.

    2012-06-01

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

    The experiment was conducted to evaluate the ingestive behavior of lambs confined in individual and group stalls. We used thirty-four lambs in their growing phase, aged an average of three months, with mean initial live weight of 17.8±5.2 kg. They were allotted in a completely randomized design with 24 animals kept in individual stalls and 10 animals confined as a group. The experiment lasted for a total of 74 days, and the first 14 days were dedicated to the animals' adaption to the management, facilities and diets. The data collection period lasted 60 days, divided into three 20-d periods for the behavior evaluation. The animals were subjected to five days of visual observation during the experiment period, by the quantification of 24 h a day, with evaluations on the 15th day of each period and an interim evaluation consisting of two consecutive days on the 30th and 31st day of the experiment. The animals confined as a group consumed less (pbehavior.

    Cancrinite-group minerals occur in the late stages of alkaline (SiO2)-undersaturated magmatism and in related effusive or contact rocks. So far only few studies have been devoted to the description of the thermo-elastic behavior, phase-stability and P /T -structure evolution (at the atomic scale) of this mineral group. Cancrinite-group minerals have an open-framework structure characterized by the [CAN]-topology. The [CAN]-framework shows large 12-ring channels, parallel to the c crystallographic axis, bound by columns of cages, the so-called can units. While very limited chemical variation is observed in the framework composition (the composition is almost always [Si6Al6O24]) a remarkable chemical variability is reported for the extraframework components in the cancrinite-group minerals. Two subgroups can be identified according to the extraframework content of the can units: the cancrinite- and the davyne-subgroups, showing Na-H2O and Ca-Cl chains, respectively. The channels are stuffed by cations, anions and molecules. We aimed to model the thermo-elastic behavior and the mechanisms of the (P ,T)-induced structure evolution of cancrinite-group minerals, with special interest on the role played by the extraframework population. The study was restricted to the following (CO3)-rich and (SO4)-rich end-members: cancrinite sensu stricto {[(Na,Ca)6(CO3)1.2-1.7][Na2(H2O)2][Al6Si6O24]}, vishnevite {[(Na,Ca,K)6(SO4)][Na2(H2O)2][Al6Si6O24]}, balliranoite {[(Na,Ca)6(CO3)1.2-1.7][Ca2Cl2][Al6Si6O24]} and davyne {[(Na,Ca,K)6((SO4),Cl)][Ca2Cl2][Al6Si6O24]}. Their high-P and low-T (T single-crystal X-ray diffraction, using diamond-anvil cells and (N2)-cryosystems, respectively. The high-T behavior of cancrinite has also been studied by means of in-situ single-crystal X-ray diffraction with a resistive heater. Cancrinite minerals share a similar volume compressibility and thermal expansivity at ambient conditions (cancrinite has KV 0 = 45(2) GPa and αV,293K = 4.88(8)·10-5 K-1

    Full Text Available Background: Osteoporosis threatens the aged population especially the menopausal women and can lead to life long disability and death. Appropriate knowledge and behavior have an important role in prevention of osteoporosis. In this study the knowledge, attitude and behavior of women regarding osteoporosis is assessed and compared in different age groups.Methods: This cross sectional study includes 390 women in reproductive, premenopausal and menopausal age groups who had come to Shariati hospital clinics and each had answered the designed questionnaire. The questionnaires were scored and analyzed. Women's knowledge, attitude and behavior were assessed and compared by X2 test in the three age groups and P<0.05 was considered significant.Results: 15-30% of women didn't know what osteoporosis is and in 380 of them attitude or behavior was not good. Education had a significant effect on knowledge of women in reproductive and premenopausal ages (P=0.002, 0.04 respectively, but had no effect on their attitude or behavior. Age had a significant effect on knowledge and attitude (P=0.001 but had no effect on behavior. Age had significant effect on the knowledge that exercise can prevent osteoporosis (P=0.014 but not on attitude or behavior. Age had no effect on knowledge, attitude or behavior of daily calcium intake to prevent osteoporosis. (P=0.123, 0.12, 0.153 respectively 93% to 95% of women thought the risks of osteoporosis are less than cardiovascular disease or breast cancer.Conclusions: 15-30% of women didn't know what osteoporosis is. The total knowledge about osteoporosis was low. Although 22-75% of women younger than 54 years old had knowledge about the predisposing factors but their attitude or behavior was not good.

    Full Text Available Organizations are operating in a dynamic and turbulent environment. In these conditions, they have to make decisions for new problems or situations. Most of decisions are therefore non-programmed and unstructured, accompanied by risk and uncertainty. Moreover, the problems and situations are complex. All organizations are oriented towards group decisionmaking processes, as useful tools to cope with uncertainty and complexity. Apart from the necessity, companies are turning towards participatory processes also to benefit from the important advantages that these processes offer. Organizations have realized the importance of group decision-making processes to contribute to the creation of sustainable competitive advantages. Main objective of this paper is to show that group decision-making processes do not offer guarantee for good decisions, because the effectiveness of group is affected by many factors. So, the first thing done in this paper is discussing about the benefits and limitations that accompany the use of groups with decision-making purpose. Afterwards, we stop on the different factors that influence the group’s ability to make good decisions. The aim is to emphasize that regardless of the many advantages of groups, some factors as group size, type of communication within the group, leadership style, the norms, the differentiation of roles and statuses, cohesion and compliance degree should be the main elements to keep into consideration because they affect the effectiveness of group. In this regard, is discussed how such factors influence the quality of decision and then we try to draw some conclusions that can improve and make better and easier group decision-making processes.

  2. Influencing agent group behavior by adjusting cultural trait values.

    2010-10-01

    Social reasoning and norms among individuals that share cultural traits are largely fashioned by those traits. We have explored predominant sociological and cultural traits. We offer a methodology for parametrically adjusting relevant traits. This exploratory study heralds a capability to deliberately tune cultural group traits in order to produce a desired group behavior. To validate our methodology, we implemented a prototypical-agent-based simulated test bed for demonstrating an exemplar from intelligence, surveillance, and reconnaissance scenario. A group of simulated agents traverses a hostile territory while a user adjusts their cultural group trait settings. Group and individual utilities are dynamically observed against parametric values for the selected traits. Uncertainty avoidance index and individualism are the cultural traits we examined in depth. Upon the user's training of the correspondence between cultural values and system utilities, users deliberately produce the desired system utilities by issuing changes to trait. Specific cultural traits are without meaning outside of their context. Efficacy and timely application of traits in a given context do yield desirable results. This paper heralds a path for the control of large systems via parametric cultural adjustments.

    Full Text Available Group behavior and interactions of endangered blue whales (Balaenoptera musculus have not been systematically studied. Such behavioral data are often overlooked when assessing anthropogenic effects. Yet behavioral data are necessary to compare “normal” behaviors with behavior affected by anthropogenic factors of concern relative to effective management and recovery of blue whales. For a baseline study, we hypothesized that the response variables sighting rate, group size, calf presence and group cohesion (i.e., spacing between individuals within a group differed according to the spatio-temporal explanatory variables behavioral state, time of day, season, water depth and distance from shore. To address our hypotheses, we flew systematic line transect surveys in southern California and collected focal group data. Two sets of data were separately analyzed using different sampling approaches: (1 point sample data associated with the first sighting of a blue whale(s, and (2 extended all-occurrence focal group behavioral sampling data (i.e., focal follows collected on a subsample of all sightings while the aircraft circled at a radial distance of approximately 0.5-1 km and an altitude of 1,500 m for extended periods of 5 – 60 minutes. Chi-square contingency table and G² analyses were used to assess statistical relationships between response and explanatory variables. We conducted 18 one-week-long aerial surveys spanning October 2008 through May 2013 (at least once during every month except December, totaling 87,555 km of observation effort. Seventy blue whale sightings (117 individuals were seen, ranging in size from 1 – 6 whales, and focal follow was performed on over half (55% of these sightings. Results supported our hypotheses that blue whale group characteristics were related to behavioral state and spatio-temporal variables. Sighting rates were significantly highest during summer followed by spring, fall, and winter. Group type differed

    Full Text Available Objectives This study examined variations in the perceptions of dioxin risk among social groups defined by geographical living location, environmental education, and occupation. Dioxin risk perceptions were analyzed according to values, risk awareness, knowledge, and behavioral preferences. Methods A quasi-experimental survey was designed and conducted on individuals from seven experimental groups in Jeonju city, South Korea, including: people living near incineration facilities; people living far from incineration facilities; governmental experts; nongovernmental organization members; office workers in developmental institutes or banks; students who were enrolled in environmental-related classes; and students who were enrolled in business-related classes. Results The results show variations among groups in values, awareness and behavioral preferences. Particular attention should be given to the result that groups with higher connectedness- to-nature values show higher willingness-to-act (WTA for risk reduction. Result s can be summarized as follows. First, awareness is associated with one’s geographical setting. Second, values and WTA behaviors are related to one’s environmental-related education and occupation. Third, values are significantly related to WTA behaviors. Conclusions Different cultures, in terms of values or worldview, among groups influence their perceptions of dioxin risk and choices of risk reduction behaviors. It is important to consider values in communicating complicated long-term risk management involving public participation. Further research should be continuously conducted on the effects of multiple dimensions of values on one’s WTA for risk reduction behaviors.

  12. Comparison of feeding behavior between two different-sized groups of Japanese macaques (Macaca fuscata yakui).

    Kurihara, Yosuke; Hanya, Goro

    2015-05-13

    Group-living animals face intragroup scramble and intergroup contest competitions. Many studies have shown that larger groups bear the costs of intragroup scramble competition, which negatively affects the reproductive success of females. Unlike most primate species, Japanese macaques in the Yakushima coastal forest show increased reproductive success with group size. However, it remains unclear how group size affects the behavior of macaques. The present study examined the effects of group size on the feeding behavior of Japanese macaques in the Yakushima coastal forest. We investigated 9-13 adult females from two different-sized groups via focal animal sampling during October 2012-August 2013. We compared the feeding behavior, including patch use, between the two groups. The larger group had a larger home range and spent more time feeding, especially on mature leaves. This suggests that intragroup feeding competition should be more intense in the larger group than in the smaller group. The feeding of mature leaves might enable the larger group to increase the number of co-feeding individuals. Contrary to the predictions that the larger group travels longer distances and spends more time moving, the smaller group traveled longer distances, and spent more time moving, although the number of visited patches did not differ between the two groups. The immediate consequences of the loss of inter-group encounters could accumulate as daily travel costs, considering that group size is associated with inter-group dominance and that intergroup aggressive encounters occur frequently in the Yakushima coastal forest. This suggests that the smaller group has increased travel costs as a result of intergroup contest competition, which leads to decline in reproductive success. Am. J.

    Requirements for high levels of human performance in the unfamiliar and stressful environments associated with space missions necessitate the development of research-based technological procedures for maximizing the probability of effective functioning at all levels of personnel participation. Where the successful accomplishment of such missions requires the coordinated contributions of several individuals collectively identified with the achievement of a common objective, the conditions for characterizing a team, crew, or functional group are operationally defined. For the most part, studies of group performances under operational conditions which emphasize relatively long exposure to extended mission environments have been limited by the constraints imposed on experimental manipulations to identify critical effectiveness factors. On the other hand, laboratory studies involving relatively brief exposures to contrived task situations have been considered of questionable generality to operational settings requiring realistic group objectives.

    2007-06-01

    The author evaluated the effects of evaluation apprehension and trait procrastination on behaviors. The author examined private university students from southern California (N = 72) on two independent variables: evaluation threat (manipulated) and trait procrastination (nonmanipulated). The author found a significant interaction effect between type of evaluation threat and level of trait procrastination on the number of days to complete an assigned essay. Post hoc analyses showed high trait procrastinators in the high evaluation threat group significantly delayed returning essays compared with those in the low evaluation threat group. Also, in the low evaluation threat group, low trait procrastinators delayed more than did high trait procrastinators. These results suggest that educators can reduce behavioral delays by increasing evaluation threat, depending on a student's level of trait procrastination.

    Obesity and diabetes have caused problems for individuals with schizophrenia long before atypical antipsychotic agents. The prevalence of obesity, insulin resistance, impaired glucose tolerance, type 2 diabetes mellitus, dyslipidemia, and the Metabolic Syndrome has increased in people with schizophrenia as compared to the general population. Risk reduction studies for persons with obesity, diabetes, and cardiovascular disease indicate that cognitive/behavioral interventions that promote motivation and provide strategies to overcome the barriers in adherence to diet and activity modification are effective interventions for weight management and risk reduction. In the landmark multi-center randomized-controlled trial study, the Diabetes Prevention Project (DPP), a cognitive/behavioral intervention, was more successful in producing weight loss and preventing diabetes than the drugs metformin, troglitazone or placebo. This pilot study examined the effectiveness of a cognitive/behavioral group intervention, modified after the DPP program, in individuals with schizophrenia or schizoaffective disorder taking atypical antipsychotics in a large urban public mental health system. Outcome measures included body weight, body mass index, waist-hip ratios, and fasting glucose levels. Both groups demonstrated elevated fasting glucose levels and were obese with a mean BMI of 33. The group that received the cognitive/behavioral group intervention lost more weight than the treatment as usual group. The CB group participants lost an average of 5.4 lb or 2.9% of body weight, and those in the control group lost 1.3 lb or 0.6% body weight. The range of weight loss for the treatment group was from 1 to 20 lb. This pilot study has demonstrated that weight loss is possible with cognitive/behavioral interventions in a population with a psychotic disorder.

  18. Consistent Individual Differences Drive Collective Behavior and Group Functioning of Schooling Fish.

    The ubiquity of consistent inter-individual differences in behavior ("animal personalities") [1, 2] suggests that they might play a fundamental role in driving the movements and functioning of animal groups [3, 4], including their collective decision-making, foraging performance, and predator avoidance. Despite increasing evidence that highlights their importance [5-16], we still lack a unified mechanistic framework to explain and to predict how consistent inter-individual differences may drive collective behavior. Here we investigate how the structure, leadership, movement dynamics, and foraging performance of groups can emerge from inter-individual differences by high-resolution tracking of known behavioral types in free-swimming stickleback (Gasterosteus aculeatus) shoals. We show that individual's propensity to stay near others, measured by a classic "sociability" assay, was negatively linked to swim speed across a range of contexts, and predicted spatial positioning and leadership within groups as well as differences in structure and movement dynamics between groups. In turn, this trait, together with individual's exploratory tendency, measured by a classic "boldness" assay, explained individual and group foraging performance. These effects of consistent individual differences on group-level states emerged naturally from a generic model of self-organizing groups composed of individuals differing in speed and goal-orientedness. Our study provides experimental and theoretical evidence for a simple mechanism to explain the emergence of collective behavior from consistent individual differences, including variation in the structure, leadership, movement dynamics, and functional capabilities of groups, across social and ecological scales. In addition, we demonstrate individual performance is conditional on group composition, indicating how social selection may drive behavioral differentiation between individuals.

    2009-10-01

    The purpose of the present study was to examine how peer group processes of pressure and control and individual motivations for popularity would add to, and moderate the relationship between, childhood maltreatment and risky behavior in adolescence. A total of 1558 youth (804 girls) from three high schools in Ontario, Canada (M age = 15.02 years, SD = .86) reported on their alcohol use, delinquent behavior, childhood experiences of physical and emotional maltreatment and neglect, peer group processes involving control and individual popularity motivations. Regression analyses showed that, beyond the significant contributions of childhood maltreatment, peer group control predicted risky alcohol use and delinquent behavior. Peer group control and popularity motivations exacerbated the negative effect of physical maltreatment on delinquent behavior. Boys' experiences of peer group control were more strongly linked to alcohol use and delinquent behavior than girls'. These results suggest that there is a significant window of opportunity during adolescence where the peer group context can exacerbate or buffer childhood experiences.

    Regulating emotions, refraining from impulsive, maladaptive behavior, and communicating effectively are considered primary treatment needs among jail inmates. Dialectical behavior therapy (DBT; Linehan, 1993a) skills address these deficits and have been implemented in long-term correctional settings, but have yet to be adapted for general population inmates in short-term jail settings. This study assessed the feasibility and acceptability of a DBT skills group in a jail setting, as well as its utility in improving coping skills and emotional/behavioral dysregulation. Male jail inmates participated in an 8-week DBT skills group and completed pre- and posttest assessments of coping skills, emotional/behavioral dysregulation, and measures of treatment acceptability. Out of 27 who started therapy, 16 completed it, primarily due to involuntary attrition such as transfer to another correctional facility. Although several logistical issues arose during this pilot study, preliminary results suggest that a brief DBT skills group is feasible and acceptable in a jail setting, and may improve coping skills and reduce externalization of blame among general population jail inmates. This study lays the groundwork for larger, controlled trials of abbreviated DBT skills groups for general population inmates in short-term jail settings.

    Full Text Available Aim/purpose - Research addressing the customer engagement behavior (CEB has rapidly developed in the marketing discipline, contributing to the knowledge on network organization. However, insights into the specific outcomes of CEB remain largely nebulous. Few comprehensive conceptual frameworks of CEB effects exists in the literature to-date. The empirical verification of CEB outcomes, particularly at the firm level, is still missing. Design/methodology/approach - In this article we first provide an overview of the CEB conceptualizations and its effects. Next we develop the CEB firm-level performance outcomes framework. Finally we explore CEB process, forms and outcomes in Stanley Black & Decker, applying qualitative methodological approach (case research incl. participant observation. Findings - We propose the logically arranged CEB effects in the conceptual model integrated with marketing metrics which are related to the recent advances in customer equity and customer asset management.

    Stereotypes are fundamentally social constructs, formulated and modified through discussion and interaction with others. The present studies examined the impact of group discussion on stereotypes. In both studies, groups of participants discussed their impressions about a hypothetical target group after having read behaviors performed by target group members. These behaviors included both stereotypic and counterstereotypic examples, and the distribution of these behaviors varied across discussion group members. In some groups only 1 member knew of the counterstereotypic behaviors; in other groups this information was distributed across all group members. In general, discussion led to a polarization of the target group stereotypes, but this effect was lessened when the counterstereotypic behaviors were concentrated in 1 group member. In this case, these counterstereotypic behaviors were discussed more and retained better.

    Environmental enrichment has been widely used to improve conditions for nonhuman animals in captivity. However, there is no consensus about the best way to evaluate the success of enrichments. This study evaluated whether the proportion of time spent interacting with enrichments indicated the proportion of overall behavioral changes. Six environmental enrichments were introduced in succession to 16 captive macaws, and interaction of the animals with them as well as the behaviors of the group were recorded before and during the enrichments. All of the enrichments affected the proportions of time spent in different behaviors. Macaws interacted more with certain items (hibiscus and food tree) than with others (a toy or swings and stairs), but introduction of the enrichments that invoked the least interaction caused as many behavioral changes as those that invoked the most. Moreover, feeding behavior was only affected by the enrichment that invoked the least interaction, a change not detected by a general analysis of enrichment effects. In conclusion, little interaction with enrichment does not mean little change in behavior, and the effects of enrichments are more complex than previously considered.

    Full Text Available Introduction: Cognitive performance in patients with schizophrenia and Bipolar I disorder seems to be different from the normal individuals, that these defects affect their treatment results. Therefore, this study aimed to compare executive function and behavioral inhibition within patients suffering from schizophrenia, bipolar type I as well as a normal group. Methods: In this descriptive-comparative study, out of all patients hospitalized in daily psychiatric clinic in Najafabad in 2014 due to these disorders, 20 schizophrenia and 20 bipolar type I as well as 20 normal individuals were selected via the convinience sampling. All the study participants completed the computerizing tests including Tower of London and Go-No Go. The study data were analyzed utilizing SPSS software (ver 22 via MANOVA. Results: The study findings revealed a significant difference between the two patient groups and the normal group in regard with executive function and behavioral inhibition (p<0.05, whereas no differences were detected between schizophrenics and bipolar patient groups. Furthermore, patients suffering from schizophrenia and bipolar I mood disorder demonstrated significantly poor performance in cognitive function and behavioral inhibition compared to the normal group. Conclusion: The present study results can be significantly applied in pathology and therapy of these disorders, so as recognizing the inability of such patients can be effective in developing cognitive rehabilitation programs in these patients.

    According to alcohol expectancy theory, drinking-related information is stored in memory and, when cue activated, influences alcohol-related behavior. Priming of alcohol cues and expectancies has been shown to elicit both drinking and nonconsumptive behavior associated with alcohol consumption, such as willingness to meet with a stranger and aggression. These social influence effects have been shown to be moderated by individual differences in alcohol expectancies. In the present study, we tested whether an alcohol prime would facilitate social group bonding even in the absence of consumption, and whether such group bonding would be moderated by individually held social expectancies. One hundred twenty undergraduates (75% female) completed an alcohol expectancy measure prior to participation. Participants were primed with either alcohol or neutral beverage words and completed a collaborative group activity followed by questionnaires measuring perceived group cohesion. Several interactions were found between condition and expectancy reflecting that those in the alcohol prime condition with higher social alcohol expectancies reported greater cohesion on task-related, but not emotion-related, group measures. These findings underscore the complexity of the impact of expectancy and social behavior on drinking: the priming of alcohol expectancies may activate aspects of pro-social behavior, which may influence drinking, which in turn may feedback to positively reinforce social expectancies.

    Full Text Available Negative parental practices may influence the onset and maintenance of externalizing behavior problems, and positive parenting seem to improve children's social skills and reduce behavior problems. The objective of the present study was to describe the effects of an intervention designed to foster parents' social skills related to upbringing practices in order to reduce externalizing problems in children aged 4 to 6 years. Thirteen mothers and two care taker grandmothers took part in the study with an average of four participants per group. To assess intervention effects, we used a repeated measure design with control, pre, and post intervention assessments. Instruments used were: (a An interview schedule that evaluates the social interactions between parents and children functionally, considering each pair of child¿s and parent's behaviors as context for one another; (b A Social Skills Inventory; (c Child Behavior Checklist - CBCL. Intervention was effective in improving parent general social skills, decreasing negative parental practices and decreasing child behavior problems.

    As interest in long duration effects of space habitation increases, understanding the behavior of model organisms living within the habitats engineered to fly them is vital for designing, validating, and interpreting future spaceflight studies. A handful of papers have previously reported behavior of mice and rats in the weightless environment of space. The Rodent Research Hardware and Operations Validation (Rodent Research-1; RR1) utilized the Rodent Habitat (RH) developed at NASA Ames Research Center to fly mice on the ISS (International Space Station). Ten adult (16-week-old) female C57BL/6 mice were launched on September 21st, 2014 in an unmanned Dragon Capsule, and spent 37 days in microgravity. Here we report group behavioral phenotypes of the RR1 Flight (FLT) and environment-matched Ground Control (GC) mice in the Rodent Habitat (RH) during this long-duration flight. Video was recorded for 33 days on the ISS, permitting daily assessments of overall health and well-being of the mice, and providing a valuable repository for detailed behavioral analysis. We previously reported that, as compared to GC mice, RR1 FLT mice exhibited the same range of behaviors, including eating, drinking, exploration, self- and allo-grooming, and social interactions at similar or greater levels of occurrence. Overall activity was greater in FLT as compared to GC mice, with spontaneous ambulatory behavior, including organized 'circling' or 'race-tracking' behavior that emerged within the first few days of flight following a common developmental sequence, and comprised the primary dark cycle activity persisting throughout the remainder of the experiment. Participation by individual mice increased dramatically over the course of the flight. Here we present a detailed analysis of 'race-tracking' behavior in which we quantified: (1) Complete lap rotations by individual mice; (2) Numbers of collisions between circling mice; (3) Lap directionality; and (4) Recruitment of mice into a group

    Full Text Available The aim of this research was to analyze the effects of the participation of health, education and religious professionals in public conversation groups with LGBT people. Participants were interviewed some weeks after the groups for feedback. Professionals declared that this dialogic method (known as Public Conversations Project allowed a qualification of their practices, awareness about the challenges of talking about gender and sexual diversity at their professional’s contexts, and a broader contact with narratives of violence and discrimination against LGBT people. The structure of dialogue allowed participants to talk and listen in a less evaluative context. Differences in the effects produced by each group are discussed in relation to the differences in the group composition and to the specificities of the health, educational and religious contexts.

    The origin and development of dysphonia, particularly behavioral dysphonia, is associated with several risk factors. Here, we verified the effectiveness of group therapy in reducing the risk factors, and established the association between risk factors and sex, age, profession, and diagnosis of laryngeal disorders in patients with behavioral dysphonia. This is a descriptive, quantitative, field intervention study. Participants (n = 26, adult patients of both sexes), with a diagnosis of behavioral dysphonia, received group therapy intervention. Data for risk factors were collected pre- and posttherapy using the Vocal Screening Protocol. The data were analyzed using descriptive and inferential statistics (Student t test, chi-squared test or Spearman correlation test). The majority (80.8%, n = 21) of patients were female, 65.4% (n = 17) were not in a vocal profession, and 42.3% (n = 11) presented with a lesion in the membranous portion of the vocal fold. The number of personal risk factors decreased after group therapy (P = 0.04). In addition, age was correlated with total (P = 0.001), environmental (P = 0.002), and personal (P = 0.003) vocal risk factors posttherapy. This study revealed an association between the reduction of personal risk factors and vocal group therapy, and a correlation between age and total, environmental, and personal vocal risk factors posttherapy. Thus, maintenance and origins of the behaviors that modify the behavioral aspects of the participants directly influence the production of individual vocal habits.

    A randomized, controlled study evaluated the effectiveness of a cognitive-behavioral therapy group, based on Linehan’s dialectical behavior therapy, for inpatients with personality disorders. The treatment, a problem-solving skills group focused on parasuicidality, was compared with a discussion control group. Change was assessed by self-report measures and behavioral observations on the unit. Subjects in both groups improved significantly on most change measures, although no significant between-group differences were found. However, the treatment group patients viewed the intervention as more beneficial to them in their lives outside the hospital. The usefulness of this type of group on a short-term unit is discussed.

    Full Text Available Abstract Background When examining the prevalence of physical inactivity by gender and age, women over the age of 25 are at an increased risk for sedentary behavior. Childbearing and motherhood have been explored as one possible explanation for this increased risk. Post natal exercise studies to date demonstrate promising physical and psychological outcomes, however few physical activity interventions have been theory-driven and tailored to post natal exercise initiates. The purpose of this study was to compare the effects of a group-mediated cognitive behavioral intervention based upon social-cognitive theory and group dynamics (GMCB to a standard care postnatal exercise program (SE. Method A randomized, two-arm intervention design was used. Fifty-seven post natal women were randomized to one of two conditions: (1 a standard exercise treatment (SE and (2 a standard exercise treatment plus group-mediated cognitive behavioral intervention (GMCB. Participants in both conditions participated in a four-week intensive phase where participants received standard exercise training. In addition, GMCB participants received self-regulatory behavioral skills training via six group-mediated counseling sessions. Following the intensive phase, participants engaged in a four-week home-based phase of self-structured exercise. Measures of physical activity, barrier efficacy, and proximal outcome expectations were administered and data were analyzed using ANCOVA procedures. Results and discussion ANCOVA of change scores for frequency, minutes, and volume of physical activity revealed significant treatment effects over the intensive and home-based phases (p's Conclusion While both exercise programs resulted in improvements to exercise participation, the GMCB intervention produced greater improvement in overall physical activity, barrier efficacy and proximal outcome expectations.

    A randomized clinical trial tested the hypothesis that a flexible, case formulation-based, individual treatment approach integrating motivational interviewing strategies with cognitive-behavioral therapy (ICBT) is more efficacious than a standardized group cognitive-behavioral approach (GCBT) for perpetrators of intimate partner violence (IPV). Forty-two men presenting for services at a community domestic violence agency were randomized to receive 20 sessions of ICBT or a 20-week group cognitive-behavioral therapy (CBT) program. Participants and their relationship partners completed assessments of relationship abuse and relationship functioning at baseline and quarterly follow-ups for 1 year. Treatment uptake and session attendance were significantly higher in ICBT than GCBT. However, contrary to the study hypothesis, GCBT produced consistently equivalent or greater benefits than ICBT. Participant self-reports revealed significant reductions in abusive behavior and injuries across conditions with no differential benefits between conditions. Victim partner reports revealed more favorable outcomes for group treatment, including a statistically significant difference in psychological aggression, and differences exceeding a medium effect size for physical assault, emotional abuse, and partner relationship adjustment. In response to hypothetical relationship scenarios, GCBT was associated with greater reductions than ICBT (exceeding a medium effect) in articulated cognitive distortions and aggressive intentions. Treatment competence ratings suggest that flexible, individualized administration of CBT creates challenges in session agenda setting, homework implementation, and formal aspects of relationship skills training. Although caution is needed in generalizing findings from this small-scale trial, the results suggest that the mutual support and positive social influence available in group intervention may be particularly helpful for IPV perpetrators.

  19. Analyzing repeated measures data on individuals nested within groups: accounting for dynamic group effects.

    Researchers commonly collect repeated measures on individuals nested within groups such as students within schools, patients within treatment groups, or siblings within families. Often, it is most appropriate to conceptualize such groups as dynamic entities, potentially undergoing stochastic structural and/or functional changes over time. For instance, as a student progresses through school, more senior students matriculate while more junior students enroll, administrators and teachers may turn over, and curricular changes may be introduced. What it means to be a student within that school may thus differ from 1 year to the next. This article demonstrates how to use multilevel linear models to recover time-varying group effects when analyzing repeated measures data on individuals nested within groups that evolve over time. Two examples are provided. The 1st example examines school effects on the science achievement trajectories of students, allowing for changes in school effects over time. The 2nd example concerns dynamic family effects on individual trajectories of externalizing behavior and depression. PsycINFO Database Record (c) 2013 APA, all rights reserved.

  20. The development of collective personality: the ontogenetic drivers of behavioral variation across groups

    2014-12-01

    Full Text Available For the past decade, the study of personality has become a topic on the frontier of behavioral ecology. However, most studies have focused on exploring inter-individual behavioral variation in solitary animals, and few account for the role that social interactions may have on the development of an individual’s personality. Moreover, a social group may exhibit collective personality: an emergent behavioral phenotype displayed at the group-level, which is not necessarily the sum or average of individual personalities within that group. The social environment, in many cases, can determine group success, which then influences the relative success of all the individuals in that group. In addition, group-level personality may itself evolve, subject to the same selection pressures as individual-level behavioral variation, when the group is a unit under selection. Therefore, we reason that understanding how collective personalities emerge and change over time will be imperative to understanding individual- and group-level behavioral evolution.Personality is considered to be fixed over an individual’s lifetime. However, behavior may shift throughout development, particularly during adolescence. Therefore, juvenile behavior should not be compared with adult behavior when assessing personality. Similarly, as conditions within a group and/or the local environment can shift, group behavior may similarly fluctuate as it matures. We discuss potential within-group factors, such as group initiation, group maturation, genetic make-up of the group, and the internal social environment, and external factors, such as well as how local environment may play a role in generating group-level personalities. There are a variety of studies that explore group development or quantify group personality, but few that integrate both processes. Therefore, we conclude by discussing potential ways to evaluate development of collective personality, and propose several focal

    An unresolved controversy regarding social behaviors is exemplified when natural selection might lead to behaviors that maximize fitness at the social-group level but are costly at the individual level. Except for the special case of groups of clones, we do not have a general understanding of how and when group-optimal behaviors evolve, especially when the behaviors in question are flexible. To address this question, we develop a general model that integrates behavioral plasticity in social interactions with the action of natural selection in structured populations. We find that group-optimal behaviors can evolve, even without clonal groups, if individuals exhibit appropriate behavioral responses to each other's actions. The evolution of such behavioral responses, in turn, is predicated on the nature of the proximate behavioral mechanisms. We model a particular class of proximate mechanisms, prosocial preferences, and find that such preferences evolve to sustain maximum group benefit under certain levels of relatedness and certain ecological conditions. Thus, our model demonstrates the fundamental interplay between behavioral responses and relatedness in determining the course of social evolution. We also highlight the crucial role of proximate mechanisms such as prosocial preferences in the evolution of behavioral responses and in facilitating evolutionary transitions in individuality.

    The aim of the present study was to assess whether behavioral activation (BA) is an efficacious treatment for decreasing eating disorder symptoms in patients with obesity and binge eating disorder (BED). Ninety-six patients with severe obesity and BED were randomized to either 10 sessions of group BA or wait-list control. The study was conducted at an obesity clinic in a regular hospital setting. The treatment improved some aspects of disordered eating and had a positive effect on depressive symptoms but there was no significant difference between the groups regarding binge eating and most other symptoms. Improved mood but lack of effect on binge eating suggests that dysfunctional eating (including BED) is maintained by other mechanisms than low activation and negative mood. However, future studies need to investigate whether effects of BA on binge eating might emerge later than at post-assessment, as in interpersonal psychotherapy for bulimia nervosa. © The Author(s) 2014.

    We investigated the effects of group music intervention on aggression and self-esteem in children with highly aggressive behavior. Forty-eight children were allocated to either a music intervention group or an untreated control group. The music intervention group received 50 min of music intervention twice weekly for 15 consecutive weeks. The outcome measures were Child Behavior Checklist Aggression Problems Scale (Parents), Child Aggression Assessment Inventory (Teachers) and Rosenberg Self-esteem Scale. After 15 weeks, the music intervention group showed significant reduction of aggression and improvement of self-esteem compared with the control group. All outcome measures were significantly lower in the music intervention group than prior to treatment, while there was no change in the control group. These findings suggest that music can reduce aggressive behavior and improve self-esteem in children with highly aggressive behavior. Music intervention is an easily accessible therapy for children and as such may be an effective intervention for aggressive behavior. Further more, objective and replicable measures are required from a randomized controlled trial with a larger sample size and active comparable control. PMID:18955314

  7. Whistle rates of wild bottlenose dolphins (Tursiops truncatus): influences of group size and behavior.

    Quick, Nicola J; Janik, Vincent M

    2008-08-01

    In large social groups acoustic communication signals are prone to signal masking by conspecific sounds. Bottlenose dolphins (Tursiops truncatus) use highly distinctive signature whistles that counter masking effects. However, they can be found in very large groups where masking by conspecific sounds may become unavoidable. In this study we used passive acoustic localization to investigate how whistle rates of wild bottlenose dolphins change in relation to group size and behavioral context. We found that individual whistle rates decreased when group sizes got larger. Dolphins displayed higher whistle rates in contexts when group members were more dispersed as in socializing and in nonpolarized movement than during coordinated surface travel. Using acoustic localization showed that many whistles were produced by groups nearby and not by our focal group. Thus, previous studies based on single hydrophone recordings may have been overestimating whistle rates. Our results show that although bottlenose dolphins whistle more in social situations they also decrease vocal output in large groups where the potential for signal masking by other dolphin whistles increases.

    It has been found that health-seeking behavior has a certain impact on influenza infection. However, behaviors with/without risk perception on the control of influenza transmission among age groups have not been well quantified. The purpose of this study was to assess to what extent, under scenarios of with/without control and preventive/protective behaviors, the age-specific network-driven risk perception influences influenza infection. A behavior-influenza model was used to estimate the spread rate of age-specific risk perception in response to an influenza outbreak. A network-based information model was used to assess the effect of network-driven risk perception information transmission on influenza infection. A probabilistic risk model was used to assess the infection risk effect of risk perception with a health behavior change. The age-specific overlapping percentage was estimated to be 40%-43%, 55%-60%, and 19%-35% for child, teenage and adult, and elderly age groups, respectively. Individuals perceive the preventive behavior to improve risk perception information transmission among teenage and adult and elderly age groups, but not in the child age group. The population with perceived health behaviors could not effectively decrease the percentage of infection risk in the child age group, whereas for the elderly age group, the percentage of decrease in infection risk was more significant, with a 97.5th percentile estimate of 97%. The present integrated behavior-infection model can help health authorities in communicating health messages for an intertwined belief network in which health-seeking behavior plays a key role in controlling influenza infection.

    2010-09-01

    This study examined the neural basis of framing effects using life-death decision problems framed either positively in terms of lives saved or negatively in terms of lives lost in large group and small group contexts. Using functional MRI we found differential brain activations to the verbal and social cues embedded in the choice problems. In large group contexts, framing effects were significant where participants were more risk seeking under the negative (loss) framing than under the positive (gain) framing. This behavioral difference in risk preference was mainly regulated by the activation in the right inferior frontal gyrus, including the homologue of the Broca's area. In contrast, framing effects diminished in small group contexts while the insula and parietal lobe in the right hemisphere were distinctively activated, suggesting an important role of emotion in switching choice preference from an indecisive mode to a more consistent risk-taking inclination, governed by a kith-and-kin decision rationality.

    Teamwork has been at the core of human accomplishment across the millennia, and it was a focus of social psychological inquiry on small group behavior for nearly half a century. However, as organizations world-wide reorganized work around teams over the past two decades, the nature of teamwork and factors influencing it became a central focus of research in organizational psychology and management. In this article, I reflect on the impetus, strategy, key features, and scientific contribution of "Enhancing the Effectiveness of Work Groups and Teams," by Kozlowski and Ilgen, a review monograph published in Psychological Science in the Public Interest in 2006.

    Children who are off-task in schools struggle with completing their work and engage in disruptive behaviors. Without intervention, these behaviors tend to worsen, putting them at risk for more serious, ongoing problems throughout life. Group counseling provides opportunities for people to practice socially useful behaviors. Using a single case…

    This mixed method systematic case study applied an interpersonal stage model of the therapeutic process to examine interpersonal processes among a highly adherent Group Psychodynamic-Interpersonal Psychotherapy (GPIP) therapist and a highly adherent Group Cognitive Behavioral Therapy (GCBT) therapist and their groups of binge eating disordered (BED) patients. This is the first case study to apply the interpersonal stage model of psychotherapy to compare GCBT and GPIP methods and the first to apply the model to group therapy. Early-, middle-, and late-stage transcribed video recordings of sequential interactions among therapists and patients in each of these two time-limited group therapies were analyzed with the Structural Analysis of Social Behavior (SASB). We also provide qualitative presentations of the transcripts from each stage as context for the quantitative analyses. BED patients in both groups achieved positive outcomes for binge eating and depression. Consistent with their treatment model, the GPIP therapist was more autonomy-giving, whereas the GCBT therapist was more controlling/directive. The GPIP therapist and her group had high levels of interpersonal complementary interaction sequences in the early stage followed by lower complementarity in the middle stage. The GCBT therapist and her group showed a high-low-high pattern of complementarity across the three stage of therapy. However, overall the GPIP group had higher levels complementarity than the GCBT group. This mixed method case study of group processes based on an interpersonal stage model of psychotherapy suggested specific therapist behaviors in each modality to maximize positive therapeutic interactions at each stage of group therapy.

    This randomized control trial is an evaluation of the effectiveness of enhanced cognitive behavioral treatment (CBT-E) for eating disorders adapted for a group setting. The study aimed to examine the effects of group CBT-E on eating disorder psychopathology and additional maintaining pathology. A transdiagnostic sample of individuals with eating disorders with a BMI ≥ 18 kg/m 2 (N = 40) were randomized to an immediate-start or delayed-start condition so as to compare therapeutic effects of group CBT-E with a waitlist control. Global Eating Disorder Examination Questionnaire (EDE-Q) scores, BMI, and measures of Clinical Perfectionism, Self-Esteem, Interpersonal Difficulties, and Mood Intolerance were measured across the 8-week control period, throughout the group treatment and at 3-months post-treatment. Over 70% of those who entered the trial completed treatment. The first eight weeks of group CBT-E were more effective at reducing Global EDE-Q scores than no treatment (waitlist control). By post-treatment, good outcome (a Global EDE-Q within 1 SD of Australian community norms plus BMI ≥ 18.5) was achieved by 67.9% of treatment completers and 66.7% of the total sample. Symptom abstinence within the previous month was reported by 14.3% of treatment completers and 10.3% of the total sample. Significant reductions in Clinical Perfectionism, Self-Esteem, Interpersonal Difficulties, and Mood Intolerance were also observed. This study demonstrated that a group version of CBT-E can be effective at reducing eating disorder psychopathology in a transdiagnostic sample of individuals with eating disorders. Group CBT-E could provide a means of increasing availability of evidence-based treatment for eating disorders. © 2017 Wiley Periodicals, Inc.

    The stepping behavior of pedestrians with different age compositions in single-file experiment is investigated in this paper. The relation between step length, step width and stepping time are analyzed by using the step measurement method based on the calculation of curvature of the trajectory. The relations of velocity-step width, velocity-step length and velocity-stepping time for different age groups are discussed and compared with previous studies. Finally effects of pedestrian gender and height on stepping laws and fundamental diagrams are analyzed. The study is helpful for understanding pedestrian dynamics of movement. Meanwhile, it offers experimental data to develop a microscopic model of pedestrian movement by considering stepping behavior.

    Little is known about rural Malawian adolescents' perceptions of their sexual behavior and what would constitute an effective HIV risk-reduction program. This study explored the perceptions of Malawain adolescents using qualitative description research with focus groups. A purposive sample of 144 adolescents, ranging from 10 to 19 years of age was obtained. Subjects were then placed in focus groups separated by gender Qualitative content analysis revealed that adolescents were at risk for HIV based on the select behaviors These included early sexual debut, multiple partners, non-use of condoms and among girls older partners These adolescents acknowledged peer pressure and lack of parental supervision as factors that perpetuated these behaviors and identified two components of HIV prevention programs. For example, parental involvement and support for sexual abstinence were among the issues discussed. It is essential that HIV risk-reduction programs create ways of involving parents and of enhancing adolescents' HIV risk-reduction skills by helping them to change peer norms and to develop negotiation and assertiveness skills to in order to resist peer pressure.

    Full Text Available Theoretical models concerning Credit Unions (CUs suggest that the type of CU domination determines the way it allocates the monetary value it generates. A borrower- (saver- dominated CU benefits borrower (saver members at the expenses of saver (borrower members, and a neutral CU equally benefits its member groups.This paper applies direct measure of monetary benefits to each member group (Patin & McNiel, 1991a to testfor the existence of dominated behavior in Brazilian CUs, and is the first to apply panel data regressions to identify the determinants of CUs behavior. We use a unique panel data with 40,664 observations taken from 533 CUs affiliated with the largest Brazilian cooperative network. Results indicate Brazilian CUs are dominated by borrowers, but behave close to neutrality. Panel regression estimates show that common or multiple bond type,size and overdue loans of a CU have no effect on its behavior, the greater the total amount of loans over social capital and adjusted equity over total assets are the more likely a CU is borrower dominated, and the greater the age and current operational expenses over total asset of a CU are the more likely a CU is saver dominated.

    The workplace has been deemed a suitable location for educating many women at once about cancer screening. To determine how group education about early diagnostic methods for breast and cervical cancer effects women's behavior and readiness to receive mammography and Pap smear. This semi-interventional study was conducted at a textile factory in Istanbul, Turkey. Female workers (n= 125) were included in the study. A participant identification form and knowledge evaluation form developed for this study, along with the transtheoretical model, were used to collect data. A 45-min interactive group education was given to the participants. Upon contacting participants 3 months after group education, 15.4% (n = 11) stated that they had since received a mammogram and 9.8% (n = 7) a Pap smear. As suggested by the transtheoretical model, group education increased participants' readiness to receive cancer screening, along with their knowledge of breast and cervical cancer. Group education positively impacted women's knowledge of cancer and their readiness to receive mammography and Pap smear. Group education can potentially create awareness of cancer screening tests among women and improve their readiness to receive such tests.

    The proposed criteria of the Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition for hypersexual disorder (HD) included symptoms reported by patients seeking help for excessive and out-of-control non-paraphilic sexual behavior, including sexual behaviors in response to dysphoric mood states, impulsivity, and risk taking. Although no prior studies of cognitive-behavioral therapy (CBT) for the treatment of HD have been performed, CBT has been found effective for dysphoric mood states and impulsivity. To investigate the feasibility of a CBT manual developed for HD explored through symptom decrease, treatment attendance, and clients' treatment satisfaction. Ten men with a diagnosis of HD took part in the CBT group program. Measurements were taken before, during, and at the end of treatment and 3 and 6 months after treatment. The primary outcome was the Hypersexual Disorder: Current Assessment Scale (HD:CAS) score that measured the severity of problematic hypersexual symptoms and secondary outcomes were the Hypersexual Disorder Screening Inventory (HDSI) score, the proportion of attended sessions, and the Client Satisfaction Questionnaire (CSQ-8) score. Main results were significant decreases of HD symptoms from before to after treatment on HD:CAS and HDSI scores and a decrease in the number of problematic sexual behaviors during the course of therapy. A high attendance rate of 93% and a high treatment satisfaction score on CSQ-8 also were found. The CBT program seemed to ameliorate the symptoms of HD and therefore might be a feasible treatment option. This study provides data from a CBT program for the treatment of the specific proposed criteria of HD. Because of the small sample and lack of a control group, the results can be considered only preliminary. Although participants reported decreased HD symptoms after attending the CBT program, future studies should evaluate the treatment program with a larger sample and a randomized controlled procedure

    Excited state proton transfer studies of six Ru polypyridyl compounds with carboxylic acid/carboxylate group(s) revealed that some were photoacids and some were photobases. The compounds [RuII(btfmb)2(LL)]2+, [RuII(dtb)2(LL)]2+, and [RuII(bpy)2(LL)]2+, where bpy is 2,2'-bipyridine, btfmb is 4,4'-(CF3)2-bpy, and dtb is 4,4'-((CH3)3C)2-bpy, and LL is either dcb = 4,4'-(CO2H)2-bpy or mcb = 4-(CO2H),4'-(CO2Et)-2,2'-bpy, were synthesized and characterized. The compounds exhibited intense metal-to-ligand charge-transfer (MLCT) absorption bands in the visible region and room temperature photoluminescence (PL) with long τ > 100 ns excited state lifetimes. The mcb compounds had very similar ground state pKa’s of 2.31 ± 0.07, and their characterization enabled accurate determination of the two pKa values for the commonly utilized dcb ligand, pKa1 = 2.1 ± 0.1 and pKa2 = 3.0 ± 0.2. Compounds with the btfmb ligand were photoacidic, and the other compounds were photobasic. Transient absorption spectra indicated that btfmb compounds displayed a [RuIII(btfmb–)L2]2+* localized excited state and a [RuIII(dcb–)L2]2+* formulation for all the other excited states. Time dependent PL spectral shifts provided the first kinetic data for excited state proton transfer in a transition metal compound. PL titrations, thermochemical cycles, and kinetic analysis (for the mcb compounds) provided self-consistent pKa* values. The ability to make a single ionizable group photobasic or photoacidic through ligand design was unprecedented and was understood based on the orientation of the lowest-lying MLCT excited state dipole relative to the ligand that contained the carboxylic acid group(s).

    Student life can be stressful. Hence, we started a regular mind-body medical stress management program in 2006. By today, more than 500 students took part and evaluations showed significant results, especially with regard to a reduction of stress warning signals. For further analysis, we now decided to run a randomized controlled longitudinal trial. Participating students at Coburg University were randomized into an intervention (n = 24) or a waitlist control group (n = 19). The intervention group completed 3 sets (pre/post/follow-up) and the control group 2 sets (pre/post) of self-administered questionnaires. The questionnaires included: SF-12 Health Survey, Perceived Stress Scale (PSS), Sense of Coherence (SOC-L9), Visual Analogue Scale (VAS) concerning stress, and the Stress Warning Signs (SWS) scale. Randomly selected participants of the intervention group were also queried in qualitative interviews. The intervention consisted of an 8 week stress management group program (mind-body medical stress reduction - MBMSR). Follow-up measures were taken after 6 months. Virtually, no drop-out occurred. Our study showed significant effects in the intervention group concerning SF-12 Mental Component Scale (p = 0.05), SF-12 Physical Component Scale (p = 0.001), VAS (in general, p = 0.001) and SWS (emotional reactions, p healthy students could be demonstrated. Findings suggest that stress management might be given importance at universities that care for the performance, the quality of life, and stress-health status of their students, acknowledging and accounting for the challenging circumstances of university life, as well as the specific needs of the modern student population.

  3. Group-Wise Herding Behavior in Financial Markets: An Agent-Based Modeling Approach

    Kim, Minsung; Kim, Minki

    2014-01-01

    In this paper, we shed light on the dynamic characteristics of rational group behaviors and the relationship between monetary policy and economic units in the financial market by using an agent-based model (ABM), the Hurst exponent, and the Shannon entropy. First, an agent-based model is used to analyze the characteristics of the group behaviors at different levels of irrationality. Second, the Hurst exponent is applied to analyze the characteristics of the trend-following irrationality group. Third, the Shannon entropy is used to analyze the randomness and unpredictability of group behavior. We show that in a system that focuses on macro-monetary policy, steep fluctuations occur, meaning that the medium-level irrationality group has the highest Hurst exponent and Shannon entropy among all of the groups. However, in a system that focuses on micro-monetary policy, all group behaviors follow a stable trend, and the medium irrationality group thus remains stable, too. Likewise, in a system that focuses on both micro- and macro-monetary policies, all groups tend to be stable. Consequently, we find that group behavior varies across economic units at each irrationality level for micro- and macro-monetary policy in the financial market. Together, these findings offer key insights into monetary policy. PMID:24714635

    This contribution investigates the addition of poly(styrene-stat-chloromethylstyrene (ClMS))s as dewetting inhibitors of polystyrene (PS) thin films with thicknesses ranging from 12 to 38 nm. The ClMS ratios in the copolymers are 5, 25 and 45 mol%. Atomic force microscopy and optical microscopy are utilized to follow morphological changes of blended PS/copolymer films upon annealing above their glass transition temperatures. We have found that thermal stability of the PS films is greatly improved when a small amount of the copolymers is added into the system. The polar ClMS groups provide anchoring sites with the polar SiO{sub x}/Si substrate while the styrene segments favorably interact with the PS matrix. The effectiveness of the copolymers as dewetting inhibitors is also found to increase with mole ratio of ClMS group. While the stability of PS films is systematically improved upon addition of the highly substituted copolymers, using the copolymer with relatively low ratio of ClMS group could lead to the opposite result. This class of copolymers can be utilized for improving thermal stability of ultrathin PS films. The fundamental knowledge from this study is also important for designing or selecting structure of additives used to improve the stability of polymeric thin films. - Highlights: Black-Right-Pointing-Pointer Efficient method for improving stability of polystyrene (PS) thin films. Black-Right-Pointing-Pointer Poly(styrene-stat-chloromethylstyrene)s are used as dewetting inhibitors. Black-Right-Pointing-Pointer Thermal stability of blended PS/copolymers greatly improved.

    Along with physical and biological changes, a tremendous amount of upheaval and adjustment accompany the pregnancy and postpartum period of a woman's life that together can often result in what is commonly known as postpartum depression. However, anxiety disorders have been found to be more frequent than depression during pregnancy and at least as common, if not more so, during the postpartum period, e.g., Brockington et al., (Archieves Women's Ment Health 9:253-263, 2006; Wenzel et al. (J Anxiety Disord, 19:295-311, 2005). Cognitive-behavioral therapy (CBT) is a well-established psychological treatment of choice for anxiety; however, few studies have specifically examined a cognitive-behavioral intervention targeting perinatal anxiety. This pilot study examined the effectiveness of a cognitive-behavioral group treatment (CBGT) program specifically tailored to address perinatal anxiety in 10 women who were either pregnant or within 12 months postpartum. Participants were recruited from a women's clinic at an academic hospital setting, with anxiety identified as their principal focus of distress. Following a diagnostic interview confirming a primary anxiety disorder and completion of assessment measures, participants completed a 6-week CBGT program. There was a statistically significant reduction in anxiety and depressive symptoms following the CBGT program (all p anxiety. These findings suggest that CBGT for perinatal anxiety is a promising treatment for both anxiety and depressive symptoms experienced during the perinatal period. Further studies are needed to evaluate the treatment efficacy through larger controlled trials.

    The conduct problems of children with callous-unemotional (CU) traits (i.e., lack of empathy, lack of guilt/lack of caring behaviors) are particularly resistant to current behavioral interventions, and it is possible that differential sensitivities to punishment and reward may underlie this resistance. Children with conduct problems and CU (CPCU) are less responsive to behavioral punishment techniques (e.g., time-out), whereas reward techniques (e.g., earning points for prizes or activities) are effective for reducing conduct problems. This study examined the efficacy of modified behavioral interventions, which de-emphasized punishment (Condition B) and emphasized reward techniques (Condition C), compared with a standard behavioral intervention (Condition A). Interventions were delivered through a summer treatment program over 7 weeks with an A-B-A-C-A-BC-A design to a group of 11 children (7-11 years; 91% male). All children were diagnosed with either oppositional defiant disorder or conduct disorder, in addition to attention-deficit hyperactivity disorder. Results revealed the best treatment response occurred during the low-punishment condition, with rates of negative behavior (e.g., aggression, teasing, stealing) increasing over the 7 weeks. However, there was substantial individual variability in treatment response, and several children demonstrated improvement during the modified intervention conditions. Future research is necessary to disentangle treatment effects from order effects, and implications of group treatment of CPCU children (i.e., deviancy training) are discussed. Copyright © 2013.

    Full Text Available Low-income youth experience social-emotional problems linked to chronic stress that are exacerbated by lack of access to care. Drumming is a non-verbal, universal activity that builds upon a collectivistic aspect of diverse cultures and does not bear the stigma of therapy. A pretest-post-test non-equivalent control group design was used to assess the effects of 12 weeks of school counselor-led drumming on social-emotional behavior in two fifth-grade intervention classrooms versus two standard education control classrooms. The weekly intervention integrated rhythmic and group counseling activities to build skills, such as emotion management, focus and listening. The Teacher’s Report Form was used to assess each of 101 participants (n = 54 experimental, n = 47 control, 90% Latino, 53.5% female, mean age 10.5 years, range 10–12 years. There was 100% retention.

    Utilizing living organisms' abilities is an effective approach to realize flexible and unconventional computing. One possible bio-inspired computer might be developed from animal collective research by clarifying collective behaviors. Therefore, it is important to reveal how collective animal behaviors emerge. In many studies, individuals departing from the other individualsare generally ignored. Is it not possible that such departing individuals contribute to the organization of such collectives? To investigate the effects of individuals departing from a collective against collective behaviors, we observed and analyzed the behaviors of 40 soldier crabs in four types of experimental arenas. The recorded behaviors demonstrate a temporally changing pattern and the existence of departing individuals. We analyzed the relationship between global activity and cohesion levels and verified the features of departing individuals. The results imply that departing individuals contribute to collective behaviors.

    Two studies were conducted to develop an understanding of factors that drive user expectations when navigating between discrete elements on a display via a limited degree-of-freedom cursor control device. For the Orion Crew Exploration Vehicle spacecraft, a free-floating cursor with a graphical user interface (GUI) would require an unachievable level of accuracy due to expected acceleration and vibration conditions during dynamic phases of flight. Therefore, Orion program proposed using a "caged" cursor to "jump" from one controllable element (node) on the GUI to another. However, nodes are not likely to be arranged on a rectilinear grid, and so movements between nodes are not obvious. Proximity between nodes, direction of nodes relative to each other, and context features may all contribute to user cursor movement expectations. In an initial study, we examined user expectations based on the nodes themselves. In a second study, we examined the effect of context features on user expectations. The studies established that perceptual grouping effects influence expectations to varying degrees. Based on these results, a simple rule set was developed to support users in building a straightforward mental model that closely matches their natural expectations for cursor movement. The results will help designers of display formats take advantage of the natural context-driven cursor movement expectations of users to reduce navigation errors, increase usability, and decrease access time. The rules set and guidelines tie theory to practice and can be applied in environments where vibration or acceleration are significant, including spacecraft, aircraft, and automobiles.

    Trichotillomania is a psychiatric condition characterized by the chronic pulling and plucking of one's own hair. Cognitive-behavioral therapy shows promise as a treatment for trichotillomania and might be preferable to pharmacotherapy. However, there have been no randomized, controlled studies of the efficacy of group cognitive-behavioral therapy. We evaluated 44 subjects, recruited from April 2009 to May 2010, all of whom met DSM-IV criteria for a diagnosis of trichotillomania. Subjects were randomized to receive 22 sessions of either group cognitive-behavioral therapy or group supportive therapy (control). Treatment evaluation was non-blind and used self-report scales. The primary outcome measure was the improvement of hair-plucking behavior as assessed by the Massachusetts General Hospital Hairpulling Scale. Secondary measures included scores on the Beck Depression Inventory, the Beck Anxiety Inventory, and the Social Adjustment Scale-Self-Report. Both groups showed significant posttreatment improvement in the scores from the Massachusetts General Hospital Hairpulling Scale (F = 23.762, P behavior over time was significantly greater in the study group than in the control group (F = 3.545, P cognitive-behavioral therapy is a valid treatment for trichotillomania. This treatment model should be further revised and expanded to address comorbidities such as anxiety and social maladjustment.

    This study classified environmentally-conscious behaviors of residents (n = 335) along Lake Biwa as a common goods into personal and group behavioral intentions, and examined the determinants of these intentions. Identification with the community was a social identity, and differed from attachment to Lake Biwa, which was defined as topophilia. The results indicated that group behavior was affected by topophilia, while personal behavior was influenced by general attitudes about the environmental problems of the lake and evaluations of the cost for the behavior. Community identity had a significant effect on both personal and group behavior. Rational or emotional decision making processes resulted in two different types of environmentally-conscious behaviors.

    Variation in group composition and environment can affect helping behavior in cooperative breeders. Understanding of how group size, traits of individuals within groups, food abundance, and predation risk simultaneously influence helping behavior is limited. We evaluated pup-guarding behavior in gray wolves (Canis lupus) to assess how differences in individuals, groups, and environment affect helping behavior. We used data from 92 GPS-collared wolves in North America (2001–2012) to estimate individual pup-guarding rates. Individuals in groups with low helper-to-pup ratios spent more time guarding young than those in groups with more helpers, an indication of load-lightening. Female helpers guarded more than male helpers, but this relationship weakened as pups grew. Subset analyses including data on helper age and wolf and prey density showed such factors did not significantly influence pup-guarding rates. We show that characteristics of individuals and groups have strong influences on pup-guarding behavior in gray wolves, but environmental factors such as food abundance and predation risk from conspecifics were not influential.

    Full Text Available Abstract Background Although patients with Treatment Resistant Depression (TRD often have impaired social functioning, few studies have investigated the effectiveness of psychosocial treatment for these patients. We examined whether adding group cognitive behavioral therapy (group-CBT to medication would improve both the depressive symptoms and the social functioning of patient with mild TRD, and whether any improvements would be maintained over one year. Methods Forty-three patients with TRD were treated with 12 weekly sessions of group-CBT. Patients were assessed with the Global Assessment of Functioning scale (GAF, the 36-item Short-Form Health Survey (SF-36, the Hamilton Rating Scale for Depression (HRSD, the Dysfunctional Attitudes Scale (DAS, and the Automatic Thought Questionnaire-Revised (ATQ-R at baseline, at the termination of treatment, and at the 12-month follow-up. Results Thirty-eight patients completed treatment; five dropped out. For the patients who completed treatment, post-treatment scores on the GAF and SF-36 were significantly higher than baseline scores. Scores on the HRSD, DAS, and ATQ-R were significantly lower after the treatment. Thus patients improved on all measurements of psychosocial functioning and mood symptoms. Twenty patients participated in the 12-month follow-up. Their improvements for psychosocial functioning, depressive symptoms, and dysfunctional cognitions were sustained at 12 months following the completion of group-CBT. Conclusions These findings suggest a positive effect that the addition of cognitive behavioural group therapy to medication on depressive symptoms and social functioning of mildly depressed patients, showing treatment resistance.

    Rational models in decision processes are marked out by many anomalies, caused by behavioral issues. We point out the importance of information in causing inconsistent preferences in a decision process. In a single or multi agent decision process each mental model is influenced by the presence, the absence or false information about the problem or about other members of the decision making group. The difficulty in modeling these effects increases because behavioral biases influence also the m...

    Conduct a pilot trial testing whether a new cognitive-behavioral (CB) group prevention program that incorporated cognitive-dissonance change principles was feasible and appeared effective in reducing depressive symptoms and major depressive disorder onset relative to a brochure control condition in college students with elevated depressive symptoms. 59 college students (M age = 21.8, SD = 2.3; 68% female, 70% White) were randomized to the 6-session Change Ahead group or educational brochure control condition, completing assessments at pretest, posttest, and 3-month follow-up. Recruitment and screening methods were effective and intervention attendance was high (86% attended all 6 sessions). Change Ahead participants showed medium-large reductions in depressive symptoms at posttest (M d = 0.64), though the effect attenuated by 3-month follow-up. Incidence of major depression onset at 3-month follow-up was 4% for Change Ahead participants versus 13% (difference ns). Change Ahead appears highly feasible and showed positive indications of reduced acute phase depressive symptoms and MDD onset relative to a minimal intervention control in this initial pilot. Given the brevity of the intervention, its apparent feasibility, and the lack of evidence-based depression prevention programs for college students, continued evaluation of Change Ahead appears warranted.

    Full Text Available Abstract Background A number of studies have provided strong evidence for the use of cognitive behavior therapy (CBT in the treatment of social anxiety disorder (SAD. However, all of the previous reports were from Europe and North America and it is unknown whether Western psychological therapies are effective for SAD in non-Western cultures. The present pilot study aimed to evaluate CBT program for SAD which was originally developed for Western patients, among Japanese patients. Methods Fifty-seven outpatients who participated in group CBT for SAD were evaluated using eight self-reported and one clinician-administered questionnaires to measure various aspects of SAD symptomatology at the beginning and at the end of the program. Pre- and post-treatment scores were compared and the magnitude of treatment effect was quantified as well based once on the intention-to-treat (ITT and once among the completers only. We also examined baseline predictors of the CBT outcomes. Results Seven patients (12% did not complete the program. For the ITT sample, the percentage of reduction was 20% to 30% and the pre to post treatment effect sizes ranged from 0.37 to 1.01. Among the completers, the respective figures were 20% to 33% and 0.41 to 1.19. We found no significant pretreatment predictor of the outcomes. Conclusion Group CBT for SAD is acceptable and can bring about a similar degree of symptom reduction among Japanese patients with SAD as among Western patients.

  10. The renormalization group in effective chiral theories

    2007-09-01

    The dilepton production within the heavy ions collisions (CERN/SPS, SIS/HADES, RHIC) and the behaviour of vector mesons (in particular the rho meson) are among the main topics of quantum chromodynamics (QCD) in hadronic matter. One of the main goals is the study of partial or total restoration of chiral symmetry SU(2) x SU(2), for which effective theories need to be used. One of the important difficulties is to build a theory which allows to obtain predictions when approaching the phase transition by taking into account the phenomenological constraints at low temperature and/or density. The model used here (developed by M. Urban) is based on the gauged (rho and al mesons) linear sigma model adjusted (in practice the local symmetry is only approximate) to reproduce the phenomenology very well. The first part of this thesis consists in presenting a new cut-off based regularization scheme preserving symmetry requirements. The motivation of such a method is a correct accounting of quadratic and logarithmic divergences in view of their intensive use for the renormalisation group equations. For illustrative purposes we have applied it to QED in 4 and 5 dimensions. The second part of this work is devoted to the derivation of the RGE and their resolution. In particular, we show that both restorations (traditional and vector manifestation) can be obtained from our equations, but the most likely remains the 'traditional' Ginzburg-Landau scenario.

    The protection of the unreacted residual aminopropyl groups of CSP 2 was found to improve the retention and the resolution factors for the resolution of racemic compounds containing a primary amino group. However, the size of the protecting acyl group should not be too bulky. As a protecting acyl group, acetyl or butyryl group seems to be good enough for the improved retention and the improved resolution. However, the separation factors were found to decrease slightly when the unreacted residual aminopropyl groups of the CSP are protected by an acyl group.

    Bulk polymer-polymer, and block copolymer, phase behaviors have traditionally been interpreted using mean-field theories. Recent small-angle neutron scattering (SANS) studies of critical phenomena in model binary polymer mixtures confirm that non-mean-field behavior is restricted to a narrow range of temperatures near the critical point, in close agreement with the Ginzburg criterion. In contrast, strong derivations from mean-field behavior are evident in SANS and rheological measurements on model block copolymers more than 50C above the order-disorder transition (ODT), which can be attributed to sizeable composition fluctuations. Such fluctuation effects undermine the mean-field assumption, conventionally applied to bulk polymers, and result in qualitative changes in phase behavior, such as the elimination of a thermodynamic stability limit in these materials. The influence of fluctuation effects on block copolymer and binary mixture phase behavior is compared and contrasted in this presentation

    Graphene aerogel has attracted great attention due to its unique properties, such as ultralow density, superelasticity, and high specific surface area. It shows huge potential in energy devices, high-performance pressure sensors, contaminates adsorbents, and electromagnetic wave absorbing materials. However, there still remain some challenges to further promote the development and real application of graphene aerogel including cost-effective scalable fabrication and miniaturization with group effect. This study shows millimeter-scale superelastic graphene aerogel spheres (GSs) with group effect and multifunctionality. The GSs are continuously fabricated on a large scale by wet spinning of graphene oxide liquid crystals followed by facile drying and thermal annealing. Such GS has an unusual core-shell structure with excellent elasticity and specific strength. Significantly, both horizontally and vertically grouped spheres exhibit superelasticity comparable to individual spheres, enabling it to fully recover at 95% strain, and even after 1000 compressive cycles at 70% strain, paving the way to wide applications such as pressure-elastic and adsorbing materials. The GS shows a press-fly behavior with an extremely high jump velocity up to 1.2 m s -1 . For the first time, both free and oil-adsorbed GSs are remotely manipulated on water by electrostatic charge due to their ultralow density and hydrophobic properties. © 2017 WILEY-VCH Verlag GmbH & Co.

    2017-10-01

    Offender engagement in group offending behavior programs is poorly understood and under-theorized. In addition, there is no research on facilitators' engagement. This article presents the first ever theory to address this gap. A Program Engagement Theory (PET) was derived from a constructivist grounded theory analysis that accounts for both facilitators' and offenders' engagement in group offending behavior programs (GOBPs). Interviews and session observations were used to collect data from 23 program facilitators and 28 offenders (group members). The analysis revealed that group members' engagement involved shared identities and moving on as a group. In turn, this was dependent on facilitators personalising treatment frameworks and establishing a hook to help group members move on. The PET emphasizes the importance of considering change during treatment as a process rather than simply a program outcome. Solution-focused (SF) programs were more conducive to engagement and the change process than offence-focused programs.

The aim of the current study was to develop a manual and investigate the efficacy of group cognitive–behavioral therapy (G-CBT for female bipolar adolescents. Materials and Methods: During the first qualitative phase of a mixed-methods study, a manual of G-CBT was developed. Then, 32 female bipolar adolescents aged 12–19 years old, receiving usual maintenance medications (UMM, were selected. Participants were randomized to the control (UMM and intervention group (5, 2 h weekly sessions based on G-CBT manual with UMM. The parents in intervention group participated in three parallel sessions. All participants filled the following questionnaires before 1, 3, and 6 months after the initiation of the study: Young Mania Rating Scale, Children Depression Inventory and Global Assessment of Functioning. The results were analyzed using SPSS 21 software. The concurrent qualitative phase was analyzed through thematic analysis. Results: The results showed no significant differences in all questionnaires' scores through intervention and follow-up sessions (P > 0.05. However, using cutoff point of CDI, G-CBT was effective for intervention group (relapse rate: 25% vs. 44.4%. Two themes were extracted from the second qualitative phase: emotion recognition and emotion regulation, especially in anger control. Conclusions: The results showed that the addition of G-CBT to UMM leads to decrease in the depressive scores but has no effect on manic symptoms and relapse rate.

    Full Text Available Background and Objective Pharmacotherapy currently widely used in the treatment of insomnia can be helpful in transient insomnia, but research regarding its effectiveness and safety of long-term use is not enough. Therefore, to complement the limitations of pharmacotherapy in the treatment of patients with insomnia, non-pharmacologic treatment methods (cognitive behavioral therapy, CBT are used. But CBT for insomnia appear to be costly and time-consuming compared to pharmacotherapy, clinical practice in the field can be difficult to be applied. We took the format of group therapy rather than individual therapy to complement the disadvantages of CBT and now we would like to have a thought into its meaning by reporting the effectiveness of group CBT for insomnia. Methods Patients were recruited at Sleep Center of St. Vincent’s Hospital, 2 men and 3 women led to a group of five patients. CBT is a treatment for correction factors that cause and maintain insomnia, it includes a variety of techniques such as sleep hygiene education, stimulus control, sleep restriction, relaxation and cognitive therapy. A series of treatment were performed five sessions once a week with a frequency from February to March 2012 and were proceeded for about 1 hour and 30 minutes per session. Results Results indicated that the subjective quality of sleep and sleep efficiency of all patients improved and Pittsburgh Sleep Quality Index and Beck Depression Inventory were decreased in spite of reducing dose of medication. Conclusions Like these cases, we can contribute to reduce the time and economic burden by performing group CBT for insomnia rather than individual therapy.

    The objective of this review was to investigate whether Chinese population groups that do not belong to classical high risk groups show an increasing trend of engaging in high-risk sexual behaviors. We systematically searched the English and Chinese literature on sexual risk behaviors published between January 1980 and March 2012 in PubMed and the China National Knowledge Infrastructure (CNKI). We included observational studies that focused on population groups other than commercial sex workers (CSWs) and their clients, and men who have sex with men (MSM) and quantitatively reported one of the following indicators of recent high-risk sexual behavior: premarital sex, commercial sex, multiple sex partners, condom use or sexually transmitted infections (STIs). We used generalized linear mixed model to examine the time trend in engaging in high-risk sexual behaviors. We included 174 observational studies involving 932,931 participants: 55 studies reported on floating populations, 73 on college students and 46 on other groups (i.e. out-of-school youth, rural residents, and subjects from gynecological or obstetric clinics and premarital check-up centers). From the generalized linear mixed model, no significant trends in engaging in high-risk sexual behaviors were identified in the three population groups. Sexual risk behaviors among certain general population groups have not increased substantially. These groups are therefore unlikely to incite a STI/HIV epidemic among the general Chinese population. Because the studied population groups are not necessarily representative of the general population, the outcomes found may not reflect those of the general population.

    Few studies have examined theoretically informed constructs related to hepatitis B (HBV) testing, and comparisons across studies are challenging due to lack of uniformity in constructs assessed. The present analysis examined relationships among Health Behavior Framework factors across four Asian American groups to advance the development of theory-based interventions for HBV testing in at-risk populations. Data were collected from 2007-2010 as part of baseline surveys during four intervention trials promoting HBV testing among Vietnamese-, Hmong-, Korean- and Cambodian-Americans (n = 1,735). Health Behavior Framework constructs assessed included: awareness of HBV, knowledge of transmission routes, perceived susceptibility, perceived severity, doctor recommendation, stigma of HBV infection, and perceived efficacy of testing. Within each group we assessed associations between our intermediate outcome of knowledge of HBV transmission and other constructs, to assess the concurrent validity of our model and instruments. While the absolute levels for Health Behavior Framework factors varied across groups, relationships between knowledge and other factors were generally consistent. This suggests similarities rather than differences with respect to posited drivers of HBV-related behavior. Our findings indicate that Health Behavior Framework constructs are applicable to diverse ethnic groups and provide preliminary evidence for the construct validity of the Health Behavior Framework.

    We observed a group of three young female Somali wild asses to develop an ethogram of social behavior in the first phase of a longer term study of social, sexual, and maternal/infant behavior. The most unexpected finding was the frequency and extent of aggressive interactions, which included Charge, Drive, Neck Wrestle, Head Butt, and Body Slam, behaviors previously reported only for males of other equid species. The overall frequency of aggressive behavior was higher than that of affiliative behavior (84±16.5 vs. 32±5.5, P=0.03), yet no injuries occurred. The dyadic directionality of aggressive behavior suggested a dominance hierarchy, a feature not previously reported for either wild ass or domestic donkeys. The aggression observed may be an accurate representation of the behavior of this species, or their relatively young ages, or their recent transfer from their natal group through quarantine and into a new enclosure may have heightened agonistic tendencies. Further studies will determine whether with time their aggressive behavior becomes more intense or dissipates with maturity. © 2011 Wiley Periodicals, Inc.

    Drawing on the group-norms theory of organizational citizenship behaviors and person-environment fit theory, we introduce and test a multilevel model of the effects of additive and dispersion composition models of team members' personality characteristics on group norms and individual helping behaviors. Our model was tested using regression and random coefficients modeling on 102 research and development teams. Results indicated that high mean levels of extraversion are positively related to individual helping behaviors through the mediating effect of cooperative group norms. Further, low variance on agreeableness (supplementary fit) and high variance on extraversion (complementary fit) promote the enactment of individual helping behaviors, but only the effects of extraversion were mediated by cooperative group norms. Implications of these findings for theories of helping behaviors in teams are discussed. PsycINFO Database Record (c) 2014 APA, all rights reserved.

    The aim of our study was to evaluate the effectiveness of Cognitive Behavioral Group Therapy (CBGT) in the treatment of Panic Disorder (PD) and to compare the treatment outcome of CBGT versus Paroxetine pharmacotherapy. Fifty seven patients referred to our anxiety disorder clinic for the treatment of PD were randomly allocated to receive either CBGT or Paroxetine. Follow up was done by a masked rater after four and twelve weeks of treatment in order to compare the efficacy of CBGT versus Paroxetine. CBGT and Paroxetine were both effective in the short-term treatment of PD. Assessments at weeks four and twelve of treatment showed no statistically significant differences between the two groups in terms of treatment outcome. Treatment with CBGT alone for the acute phase of PD appears to be equally efficacious to treatment with Paroxetine alone. Our study shows that CBGT produced beneficial results, for it was associated with a reduction in the number and frequency of panic attacks and with an improved feeling of well-being.

  10. Influence of information on behavioral effects in decision processes

    2015-07-01

    Full Text Available Rational models in decision processes are marked out by many anomalies, caused by behavioral issues. We point out the importance of information in causing inconsistent preferences in a decision process. In a single or multi agent decision process each mental model is influenced by the presence, the absence or false information about the problem or about other members of the decision making group. The difficulty in modeling these effects increases because behavioral biases influence also the modeler. Behavioral Operational Research (BOR studies these influences to create efficient models to define choices in similar decision processes.

    To test group-based Female-Specific Cognitive Behavioral Therapy (G-FS-CBT) for women with Alcohol Use Disorder (AUD) against an individual Female-Specific Cognitive Behavioral Therapy (I-FS-CBT). This aims of this paper are to describe G-FS-CBT development, content, feasibility, acceptability, group process, engagement in treatment, and within- and post-treatment outcomes. Women with AUD (n=155) were randomly assigned to 12 manual-guided sessions of G-FS-CBT or I-FS-CBT; 138 women attended at least one treatment session. Women in G-FS-CBT attended fewer sessions (M=7.6) than women in I-FS-CBT (M=9.7; p<.001). Women in both conditions reported high satisfaction with the treatments. Independent coders rated high fidelity of delivery of both G-FS-CBT and I-FS-CBT. Therapeutic alliance with the therapist was high in both conditions, with I-FS-CBT being slightly but significantly higher than G-FS-CBT. In the first six weeks of treatment, women in both treatment conditions significantly reduced their percent drinking days (PDD) and percent heavy days drinking (PHD) by equivalent amounts, maintained through the rest of treatment and the 12month follow up with no treatment condition effects. Women reported significant improvement in all but one of the secondary outcomes during treatment; gains made during treatment in depression, anxiety, autonomy, and interpersonal problems were maintained during the follow-up period, while gains made during treatment in use of coping skills, self-efficacy for abstinence, self-care, and sociotropy deteriorated over follow up but remained improved compared to baseline. Findings support the feasibility, acceptability, and efficacy of a group format for female-specific CBT for AUD, a new 12-session, single gender, community friendly, group therapy with programming specifically for women. Similar, positive outcomes for individual and group treatment formats were found for drinking, mood, coping skills, self-confidence, interpersonal

    Marika Rullo

    Full Text Available In the classic black sheep effect (BSE an ingroup deviant member is usually evaluated more negatively than the corresponding outgroup deviant. This effect is usually obtained by using scenarios and asking people to imagine the situation as vividly as possible. The present study proposes a new method to investigate the BSE by considering the behavioral and physiological reactions to unfair behavior (aggressive game behavior in a realistic experimental group-setting. The study involved 52 university students in a minimal group setting who performed a modified version of the competitive reaction time (CRT task adapted to be played in groups of four people. The classic BSE was replicated for evaluation but not for the behavioral reactions (retaliate to aggression to deviants. More interestingly, a negative relationship emerged in the ingroup deviant condition between the level of behavioral derogation and the systolic blood pressure level.

    We assessed whether an attachment-based treatment, Group Psychodynamic Interpersonal Psychotherapy (GPIP) had a greater impact compared to Group Cognitive Behavioral Therapy (GCBT) on Cold/Distant and Intrusive/Needy interpersonal problems. Ninety-five individuals with Binge Eating Disorder (BED) were randomized to GPIP or GCBT and assessed at pre-, post-, and six months post-treatment. Both therapies resulted in a significant decrease in all eight interpersonal problem subscales except the Nonassertive subscale. GPIP resulted in a greater reduction in the Cold/Distant subscale compared to GCBT, but no differences were found for changes in the Intrusive/Needy subscale. GPIP may be most relevant for those with BED who have Cold/Distant interpersonal problems and attachment avoidance.

    Social transmission of information is vital for many group-living animals, allowing coordination of motion and effective response to complex environments. Revealing the interaction networks underlying information flow within these groups is a central challenge. Previous work has modeled interactions between individuals based directly on their relative spatial positions: each individual is considered to interact with all neighbors within a fixed distance (metric range), a fixed number of nearest neighbors (topological range), a 'shell' of near neighbors (Voronoi range), or some combination (Figure 1A). However, conclusive evidence to support these assumptions is lacking. Here, we employ a novel approach that considers individual movement decisions to be based explicitly on the sensory information available to the organism. In other words, we consider that while spatial relations do inform interactions between individuals, they do so indirectly, through individuals' detection of sensory cues. We reconstruct computationally the visual field of each individual throughout experiments designed to investigate information propagation within fish schools (golden shiners, Notemigonus crysoleucas). Explicitly considering visual sensing allows us to more accurately predict the propagation of behavioral change in these groups during leadership events. Furthermore, we find that structural properties of visual interaction networks differ markedly from those of metric and topological counterparts, suggesting that previous assumptions may not appropriately reflect information flow in animal groups.

  18. The effects of radionuclides on animal behavior

    Concomitant with the expansion of the nuclear industry, the concentrations of several pollutants, radioactive or otherwise, including uranium, caesium, cadmium and cobalt, have increased over the last few decades. These elemental pollutants do exist in the environment and are a threat to many organisms. Behavior represents the integration of all the anatomical adaptations and physiological processes that occur within an organism. Compared to other biological endpoints, the effects of pollutants on animal behavior have been the focus of only a few studies. However, behavioral changes appear to be ideal for assessing the effects of pollutants on animal populations, because behavior links physiological functions with ecological processes. The alteration of behavioral responses can have severe implications for survival of individuals and of population of some species. Behavioral disruptions may derive from several underlying mechanisms: disruption of neuro-sensorial activity and of endocrines, or oxidative and metabolic disruptions. In this review, we presented an overview of the current literature in which the effects of radioactive pollutants on behavior in humans, rodents, fish and wildlife species are addressed. When possible, we have also indicated the potential underlying mechanisms of the behavioral alterations and parameters measured. In fried, chronic uranium contamination is associated with behavior alterations and mental disorders in humans, and cognitive deficits in rats. Comparative studies on depleted and enriched uranium effects in rats showed that chemical and radiological activities of this metal induced negative effects on several behavioral parameters and also produced brain oxidative stress. Uranium exposure also modifies feeding behavior of bivalves and reproductive behavior of fish. Studies of the effects of the Chernobyl accident shows that chronic irradiation to 137 Cs induces both nervous system diseases and mental disorders in humans leading

    Human groups function because members trust each other and reciprocate cooperative contributions, and reward others' cooperation and punish their non-cooperation. Here we examined the possibility that such third-party punishment and reward of others' trust and reciprocation is modulated by oxytocin, a neuropeptide generally involved in social bonding and in-group (but not out-group) serving behavior. Healthy males and females (N=100) self-administered a placebo or 24 IU of oxytocin in a randomized, double-blind, between-subjects design. Participants were asked to indicate (incentivized, costly) their level of reward or punishment for in-group (outgroup) investors donating generously or fairly to in-group (outgroup) trustees, who back-transferred generously, fairly or selfishly. Punishment (reward) was higher for selfish (generous) investments and back-transfers when (i) investors were in-group rather than outgroup, and (ii) trustees were in-group rather than outgroup, especially when (iii) participants received oxytocin rather than placebo. It follows, first, that oxytocin leads individuals to ignore out-groups as long as out-group behavior is not relevant to the in-group and, second, that oxytocin contributes to creating and enforcing in-group norms of cooperation and trust.

    The mechanisms by which odors induce instinctive behaviors are largely unknown. Odor detection in the mouse nose is mediated by >1, 000 different odorant receptors (ORs) and trace amine-associated receptors (TAARs). Odor perceptions are encoded combinatorially by ORs and can be altered by slight changes in the combination of activated receptors. However, the stereotyped nature of instinctive odor responses suggests the involvement of specific receptors and genetically programmed neural circuits relatively immune to extraneous odor stimuli and receptor inputs. Here, we report that, contrary to expectation, innate odor-induced behaviors can be context-dependent. First, different ligands for a given TAAR can vary in behavioral effect. Second, when combined, some attractive and aversive odorants neutralize one another’s behavioral effects. Both a TAAR ligand and a common odorant block aversion to a predator odor, indicating that this ability is not unique to TAARs and can extend to an aversive response of potential importance to survival. In vitro testing of single receptors with binary odorant mixtures indicates that behavioral blocking can occur without receptor antagonism in the nose. Moreover, genetic ablation of a single receptor prevents its cognate ligand from blocking predator odor aversion, indicating that the blocking requires sensory input from the receptor. Together, these findings indicate that innate odor-induced behaviors can depend on context, that signals from a single receptor can block innate odor aversion, and that instinctive behavioral responses to odors can be modulated by interactions in the brain among signals derived from different receptors.

One group received 8 sessions of BA (n = 14, and the other received 8 sessions of group CT (n = 13.Result: Analysis of covariance revealed that the BA group had a significantly greater reduction in depressive symptoms than the CT group. However, there were no significant differences between the two groups in the levels of anxiety, stress symptoms or functional impairment after treatment.Conclusion: This study found evidence for the effectiveness of BA in reducing anxiety, depressive and stress symptoms and functional impairment compared to CT. BA was more effective than CT in improving depressive symptoms and was as effective as CT in decreasing anxiety, stress and functional impairment. BA is also a cost-effective intervention, particularly in group formats.

    Despite the many works on contagion phenomena in both well-mixed systems and heterogeneous networks, there is still a lack of understanding of the intermediate regime where social group structures evolve on a similar time scale to individual-level transmission. We address this question by considering the process of transmission through a model population comprising social groups which follow simple dynamical rules for growth and breakup. Despite the simplicity of our model, the profiles produced bear a striking resemblance to a wide variety of real-world examples—in particular, empirical data that we have obtained for social (i.e., YouTube), financial (i.e., currency markets), and biological (i.e., colds in schools) systems. The observation of multiple resurgent peaks and abnormal decay times is qualitatively reproduced within the model simply by varying the time scales for group coalescence and fragmentation. We provide an approximate analytic treatment of the system and highlight a novel transition which arises as a result of the social group dynamics.

    Coordination among social animals requires rapid and efficient transfer of information among individuals, which may depend crucially on the underlying structure of the communication network. Establishing the decision-making circuits and networks that give rise to individual behavior has been a central goal of neuroscience. However, the analogous problem of determining the structure of the communication network among organisms that gives rise to coordinated collective behavior, such as is exhibited by schooling fish and flocking birds, has remained almost entirely neglected. Here, we study collective evasion maneuvers, manifested through rapid waves, or cascades, of behavioral change (a ubiquitous behavior among taxa) in schooling fish (Notemigonus crysoleucas). We automatically track the positions and body postures, calculate visual fields of all individuals in schools of ∼150 fish, and determine the functional mapping between socially generated sensory input and motor response during collective evasion. We find that individuals use simple, robust measures to assess behavioral changes in neighbors, and that the resulting networks by which behavior propagates throughout groups are complex, being weighted, directed, and heterogeneous. By studying these interaction networks, we reveal the (complex, fractional) nature of social contagion and establish that individuals with relatively few, but strongly connected, neighbors are both most socially influential and most susceptible to social influence. Furthermore, we demonstrate that we can predict complex cascades of behavioral change at their moment of initiation, before they actually occur. Consequently, despite the intrinsic stochasticity of individual behavior, establishing the hidden communication networks in large self-organized groups facilitates a quantitative understanding of behavioral contagion.

    Full Text Available Abstract: The aspect of moral development is of great concern of early childhood caregivers. Moral development, which is now better known as prosocial behaviors include behaviors such as empathy, generosity, cooperation, caring, and many more. Various attempts to build prosocial behavior has been carried out in kindergarten, including in one of international preschools  in Bandung that management class is using the multiage grouping.  According to this phenomenon which needed to be achieved, such as the form of prosocial behavior of the child at the multiage grouping, factors that affect the incidence of prosocial behavior in multiage grouping, teachers intervention to any problems relate to prosocial behavior in the multiage grouping, the efforts of teachers to develop prosocial behavior in multiage grouping, the efforts of teachers to manage classes with the concept of multiage grouping. The purpose of doing this research on the grounds of how the management class that uses multiage grouping can increase prosocial behavior of children between the age range of 3-6 years.  The method used in this study is a qualitative approach using case studies, data collection is done by observation, interview and documentation. The findings of this study represent children’s prosocial behavior in the form of cooperative behavior, friendship, helping, sharing, and caring. Children prosocial behavior should practically continually place in their environment and if the foundation is strong enough, they will easily adjust to school environment, especially in a school where the class management is using multiage grouping.

    The present study investigated mechanisms of change for two group treatments for social anxiety disorder (SAD): cognitive behavioral group therapy (CBGT) and mindfulness and acceptance-based group therapy (MAGT). Participants were treatment completers (n = 37 for MAGT, n = 32 for CBGT) from a randomized clinical trial. Cognitive reappraisal was the hypothesized mechanism of change for CBGT. Mindfulness and acceptance were hypothesized mechanisms of change for MAGT. Latent difference score (LDS) analysis results demonstrate that cognitive reappraisal coupling (in which cognitive reappraisal is negatively associated with the subsequent rate of change in social anxiety) had a greater impact on social anxiety for CBGT than MAGT. The LDS bidirectional mindfulness model (mindfulness predicts subsequent change in social anxiety; social anxiety predicts subsequent change in mindfulness) was supported for both treatments. Results for acceptance were less clear. Cognitive reappraisal may be a more important mechanism of change for CBGT than MAGT, whereas mindfulness may be an important mechanism of change for both treatments. Copyright © 2015 Elsevier Ltd.

    2017-02-01

    This study examines the relationship between job insecurity and discretionary behaviors, that is, organizational citizenship behaviors (OCB) and counterproductive work behaviors (CWB), with the purpose to extend knowledge on the theoretical explanations for these outcomes. Considering the employment relationship with the organization, two different perspectives are suggested and compared in a multiple mediator model, in order to understand the reasons for discretionary behaviors. We draw upon social exchange theory as the basis of psychological contract perceptions and we rely on the group value model to explain organizational justice evaluations. A total of 570 blue-collar workers in Italy participated in our survey. The results show that job insecurity is indirectly related to OCB and CWB through psychological contract breach and organizational injustice. Both mediational mechanisms have equivalent strength in explaining the relationships, namely, they are complementary processes in accounting for both behaviors. These findings suggest that employees' behaviors in job insecure contexts are driven not only by concerns related to the exchange of resources with the organization, but also by evaluations about their value as important members of the group. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    Full Text Available The purpose of this study is to investigate the effect of emotional intelligence on the behavior problems of boys with Externalized behavior disorder in Primary Schools. Method: This quasi-experimental study was conducted along with a pre-test, post-test, with a control group and a follow-up test. For sampling, 40 students identified with Externalized behavioral problems through the Teacher Report Form (TRF and the Child Behavior Checklist (CBCL were chosen and randomly divided into two groups (20 in the experimental group and 20 in the control group. The experimental group received emotional intelligence training program in 17 sessions (2 sessions per week, 60 minutes per session and the control group received no training beyond their regular school program. After two months, in order to examine the stability (durability of training effect, the follow-up test was conducted. Finally, the data obtained were analyzed using the statistical method of generalized estimating equations. Results: The results showed that the intervention program had created a significant difference between the scores of the experimental and control group (p<0.001 and the rate of behavioral problems (aggression, rule breaking occurrence has dropped. This was true for the follow-up results too. Conclusions: It can be concluded that Emotional Intelligence Training decreases the behavior problems of boys with Externalized behavior disorder and helps to prevent high occurrence of these problems.

    Behavioral, hormonal, and genetic processes interact reciprocally, and differentially affect behavior depending on ecological and social contexts. When individual differences are favored either between or within environments, developmental plasticity would be expected. Parental effects provide a rich source for phenotypic plasticity, including anatomical, physiological, and behavioral traits, because parents respond to dynamic cues in their environment and can, in turn, influence offspring accordingly. Because these inter-generational changes are plastic, parents can respond rapidly to changing environments and produce offspring whose phenotypes are well suited for current conditions more quickly than occurs with changes based on evolution through natural selection. I review studies on developmental plasticity and resulting phenotypes in Belding's ground squirrels (Urocitellus beldingi), an ideal species, given the competing demands to avoid predation while gaining sufficient weight to survive an upcoming hibernation, and the need for young to learn their survival behaviors. I will show how local environments and perceived risk of predation influence not only foraging, vigilance, and anti-predator behaviors, but also adrenal functioning, which may be especially important for obligate hibernators that face competing demands on the storage and mobilization of glucose. Mammalian behavioral development is sensitive to the social and physical environments provided by mothers during gestation and lactation. Therefore, maternal effects on offspring's phenotypes, both positive and negative, can be particularly strong. © The Author 2014.

    We report the faithful reproduction of the self-organized aggregation behavior of the German cockroach Blattella germanica with a group of robots. We describe the implementation of the biological model provided by Jeanson et al. in Alice robots, and we compare the behaviors of the cockroaches and the robots using the same experimental and analytical methodology. We show that the aggregation behavior of the German cockroach was successfully transferred to the Alice robot despite strong differences between robots and animals at the perceptual, actuatorial, and computational levels. This article highlights some of the major constraints one may encounter during such a work and proposes general principles to ensure that the behavioral model is accurately transferred to the artificial agents.

    Full Text Available Ethograms provide a systematic approach to identify and quantify the repertoire of behaviors of an organism. This information may assist animal welfare in zoos, increase awareness of conservation needs, and help curb high-risk behaviors during human-wildlife conflict. Our primary objective was to utilize an equid ethogram to produce activity budgets for Equus kiang males, a social ungulate that is among the least-studied mammals worldwide, and unknown to the ethological literature. We recently reported the existence of three social classes of this species; Territorial males, Bachelor males and ‘Transient’ males. Therefore, our secondary objective was to compare activity budgets in each of these three groups. We found that kiang spent >70% of their time performing six behaviors: vigilance (34%, locomotion (24.2%, resting (14.2%, mixed foraging (12.5%, browsing (5.1%, and antagonism (1.1%. Over 2% of the total behavioral investment was spent on olfactory investigations (genital sniffing, sniffing proximity and flehmen. Eleven of the eighteen behaviors differed by class. Habitat selection differed strongly by each group, with Territorial males favoring mesic sites with greater vegetation abundance. Vigilance also differed according to habitat selection, but not group size. Animals in the xeric, least vegetation-rich area were far less vigilant than animals at more attractive sites. We found that the full repertoire of behaviors, and relative investments in each, differ according to social class. These findings are a reminder that researchers should make every effort to disambiguate social class among ungulates– and other taxa where behaviors are class-dependent.

    We evaluate the technical and organizational aspects of the severe accident management guideline (SAMG), focusing on the decision-making process in the technical support center (TSC). From the technical aspects, we conclude that the present SAMG is a good tool that can assist the TSC in efficiently managing probable severe accidents. However, we suggest that the clear separation of the emergency operating procedure (EOP) and SAMG, which shifts plant control from the main control room (MCR) to the TSC, might not be an effective framework from an organizational perspective. Studies on organizational behavior demonstrate that a group decision made under a risky situation might be polarized in either a risky or cautious way. We recognize that we cannot be free from the polarization effect since the current SAMG recommends that the TSC evaluate the advantages and disadvantages of strategies to be implemented and choose the best one based on a group decision process. Illustrative examples of accident management under risky conditions are recapitulated from previous studies of the authors and we propose that the SAMG should be more proceduralized to remove this polarization from the decision-making process.

    Behavioral side effects of antiepileptic drugs (AEDs) are common including both positive and negative effects on mood, anxiety, depression, and psychosis. We aimed to evaluate behavioral patterns in rats after administration of lamotrigine, levetiracetam, phenytoin, topiramate, carbamazepine, gabapentin, pregabalin, and zonisamide. The open-field test was performed and locomotion, rearing, grooming, central latency and defecation were recorded over a 5min interval for each rat (8 rats in each group receiving AED and 16 controls). Kruskal-Wallis nonparametric test or ANOVA were used to assess differences among the groups. The experimental groups did not differ in latency to enter the center compartment, neither in the decline of locomotor activity in the 1st and the 5th minute of the observation, nor in number of rears. Significant differences among groups were observed in the total number of lines crossed, grooming, as well in the number of fecal pellets. Locomotor activity was significantly increased in lamotrigine, if compared with gabapentin and pregabalin (ANOVA; p <0.05). Rats exposed to topiramate displayed a significantly increased number of grooming (when compared to pregabalin: p<0.01). Defecation (the number of fecal pellets) significantly increased in the gabapentin and carbamazepine group. There are significant differences between AEDs in terms of their behavioral profile. It is of great importance to evaluate these effects in clinical practice to bring more clear insight into these positive or negative side effects of AEDs.

    Ant mill, caterpillar circle, bat doughnut, amphibian vortex, duck swirl, and fish torus are different names for rotating circular animal formations, where individuals turn around a common center. These "collective vortex behaviors" occur at different group sizes from pairs to several million individuals and have been reported in a large number of organisms, from bacteria to vertebrates, including humans. However, to date, no comprehensive review and synthesis of the literature on vortex behaviors has been conducted. Here, we review the state of the art of the proximate and ultimate causes of vortex behaviors. The ubiquity of this behavioral phenomenon could suggest common causes or fundamental underlying principles across contexts. However, we find that a variety of proximate mechanisms give rise to vortex behaviors. We highlight the potential benefits of collective vortex behaviors to individuals involved in them. For example, in some species, vortices increase feeding efficiency and could give protection against predators. It has also been argued that vortices could improve collective decision-making and information transfer. We highlight gaps in our understanding of these ubiquitous behavioral phenomena and discuss future directions for research in vortex studies.

    Weaned dairy calves are commonly exposed to changing physical and social environments, and ability to adapt to novel management is likely to have performance and welfare implications. We characterized how behavioral responses of weaned heifer calves develop over time after introduction to a social group. Previously individually reared Holstein heifer calves (n = 15; 60 ± 5 d of age; mean ± standard deviation) were introduced in weekly cohorts (5 ± 3 new calves/wk) to an existing group on pasture (8 ± 2 calves/group). We measured activity and behavior on the day of initial introduction and after 1 wk, when calves were exposed to regrouping (addition of younger calves and removal of older calves from the pen). Upon introduction, calves had 2 to 3 times more visits to each region of the pasture; they also spent more time at the back of the pasture, closest to where they were introduced and furthest from the feeding area (25.13 vs. 9.63% of observation period, standard error = 5.04), compared with behavior after 1 wk. Calves also spent less time feeding (5.0 vs. 9.6% of observation period, standard error = 0.82) and self-grooming (0.52 vs. 1.31% of observation period; standard error = 0.20) and more time within 1 to 3 body lengths of another calf (16.3 vs. 11.9% of observation period, standard error = 2.3) when initially grouped. We also explored whether behavioral responses to initial postweaning grouping might be associated with individual differences in behavioral flexibility. To evaluate this, we assessed cognition of individually housed calves (n = 18) at 5 wk of age using a spatial discrimination task conducted in a T-maze to measure initial learning (ability to learn the location of a milk reward) and reversal learning (ability to relearn location of the milk reward when it was switched to opposite arm of the maze). Calves were categorized by reversal learning success (passed, n = 6, or failed, n = 8). Calves that passed the reversal learning stage of the

    Full Text Available The first purpose of the present study examined whether individuals with different exercise behaviors (classified by attendance experienced different or similar cognitive patterns. It was hypothesized that different behavior would lead to different cognitive appraisals. It was predicted that there would be a difference between the three behavioral frequency groups with regard to self-efficacy measures and goal measures. The second purpose of the study was to describe, evaluate and observe whether social factors were associated with participating in exercise in groups. It was hypothesized that those who engage in exercise classes would elicit a social focus. Participants for the study included 39 females who registered in-group fitness classes at a mid-sized university. Attendance over the 10-week course was assessed and participants completed a self-report questionnaire during week seven. The attendance data were used to create 3 exercise frequency groups (regular attenders, sporadic attenders, and dropouts based on ACSM's exercise guidelines. Analysis of Variance (ANOVA, means and frequencies were used to describe the data. There were no significant differences on measures of self-efficacy, goal measures, enjoyment, and external motivation among the three groups (all p's > 0.05. An analysis of the whole group (N=39 discovered a low social focus and high ratings of self-efficacy. Continued research is necessary to investigate the benefit of social support in a group exercise setting, as well as to better understand how self-regulation through self-efficacy and goal factors influences and is influenced by actual behavior.

    China has entered the aging society, but the social support systems for the elderly are underdeveloped, which may make the elderly feel anxiety about their health and life quality. Given the prevalence of generalized anxiety disorder (GAD) in the elderly, it is very important to pay more attention to the treatment for old adults. Although cognitive behavioral therapy targeting intolerance of uncertainty (CBT-IU) has been applied to different groups of patients with GAD, few studies have been performed to date. In addition, the effects of CBT-IU are not well understood, especially when applied to older adults with GAD. Sixty-three Chinese older adults with a principal diagnosis of GAD were enrolled. Of these, 32 were randomized to receive group CBT-IU (intervention group) and 31 were untreated (control group). GAD and related symptoms were assessed using the Penn State Worry Questionnaire, Intolerance of Uncertainty Scale-Chinese Version, Beck Anxiety Inventory, Beck Depression Inventory, Why Worry-II scale, Cognitive Avoidance Questionnaire, Generalized Anxiety Disorder Questionnaire-IV, and Generalized Anxiety Disorder Severity Scale across the intervention. The changes between pre and after the intervention were collected, as well as the six-month follow-up. F test and repeated-measures ANOVA were conducted to analyze the data. Compared to control group, the measures' scores of experimental group decreased significantly after the intervention and six-month follow-up. Besides the main effects for time and group were significant, the interaction effect for group × time was also significant. These results indicated the improvement of the CBT-IU group and the persistence of effect after six months. Group CBT-IU is effective in Chinese older adults with GAD. The effects of CBT-IU on GAD symptoms persist for at least six months after treatment.

    2015-12-01

    This study examined the association between popularity in the peer group and adolescents' behavior in a dyadic context. After collecting peer nominations for popularity, 218 early adolescents (M(age) = 11.0 years) in 109 randomly composed same-sex dyads participated in a discussion task where they planned a party for their classroom. From digital recordings of the sessions, each participant's influence, involvement, skillful leadership, coercive resource control, submissiveness, positivity, and negativity were observed. Analyses with the actor-partner interdependence model (APIM) demonstrated that for girls high group level popularity was associated with a socially sensitive interaction style and influence in the dyadic context. For both boys and girls, the interaction partner's group level popularity negatively predicted their use of coercive resource control strategies and negative behavior in the dyad. For girls, in addition, the interaction partner's group level popularity also positively predicted their submissiveness and negatively predicted their task influence. These results indicate that, in particular for girls, adolescents' group level popularity plays an important role in the behavior of both peers in a cooperative dyadic context.

    2012-09-01

    Cognitive behavioral therapy (CBT) has shown to be effective in the treatment of social anxiety disorders (SAD). However, fear of social blushing is almost never measured as a therapeutic outcome variable, even though some data suggest that this dimension constitutes a specific syndrome in social anxiety spectrum, justifying specific therapeutic strategies. For these reasons, we developed a group therapy program including a combination of task concentration training (TCT) and other CBT strategies targeting fear of blushing. We aimed to investigate the efficacy of this program in an open trial conducted in 55 patients suffering from SAD (Diagnostic and statistical manual of mental disorders IV criteria) with fear of blushing. Throughout a program including eleven weekly sessions, systematic measurements of fear of blushing and other anxiety and personality dimensions were performed at inclusion, at the end of the therapy and 3 months later, in order to explore the therapeutic effects of the program on fear of blushing, social anxiety, and other dimensions (Liebowitz social anxiety scale, blushing propensity questionnaire, Rathus assertiveness scale, Rosenberg self-esteem scale, Hospital anxiety and depression scale, Sheehan disability scale). The statistical analyses compared the scores of all measurements at inclusion, at the end of the therapy, and 6 months later. We also calculated the effect size obtained after treatment, and performed a logistic regression to determine the factors associated with a remission of fear of blushing after therapy. The main outcome criterion - the Salpêtrière fear of blushing questionnaire (SFBQ) score - was significantly reduced after treatment (Passertiveness, self-esteem, anxiety, depression and disability showed significant improvement after treatment and reductions remained stable at 3-month follow-up. To be a female and to have a low SFBQ score at inclusion appeared as two independent predictors of good improvement. Despite

    Opioid use disorders are characterized in part by impairments in social functioning. Previous research indicates that laboratory rats, which are frequently used as animal models of addiction-related behaviors, are capable of prosocial behavior. For example, under normal conditions, when a 'free' rat is placed in the vicinity of rat trapped in a plastic restrainer, the rat will release or 'rescue' the other rat from confinement. The present study was conducted to determine the effects of heroin on prosocial behavior in rats. For 2 weeks, rats were given the opportunity to rescue their cagemate from confinement, and the occurrence of and latency to free the confined rat was recorded. After baseline rescuing behavior was established, rats were randomly selected to self-administer heroin (0.06 mg/kg/infusion i.v.) or sucrose pellets (orally) for 14 days. Next, rats were retested for rescuing behavior once daily for 3 days, during which they were provided with a choice between freeing the trapped cagemate and continuing to self-administer their respective reinforcer. Our results indicate that rats self-administering sucrose continued to rescue their cagemate, whereas heroin rats chose to self-administer heroin and not rescue their cagemate. These findings suggest that rats with a history of heroin self-administration show deficits in prosocial behavior, consistent with specific diagnostic criteria for opioid use disorder. Behavioral paradigms providing a choice between engaging in prosocial behavior and continuing drug use may be useful in modeling and investigating the neural basis of social functioning deficits in opioid addiction. © 2018 Society for the Study of Addiction.

  15. Framing effects in group investment decision making: role of group polarization.

    Cheng, Pi-Yueh; Chiou, Wen-Bin

    2008-02-01

    Prospect theory proposes that framing effects result in a preference for risk-averse choices in gain situations and risk-seeking choices in loss situations. However, in group polarization situations, groups show a pronounced tendency to shift toward more extreme positions than those they initially held. Whether framing effects in group decision making are more prominent as a result of the group-polarization effect was examined. Purposive sampling of 120 college students (57 men, 63 women; M age = 20.1 yr., SD = 0.9) allowed assessment of relative preference between cautious and risky choices in individual and group decisions. Findings indicated that both group polarization and framing effects occur in investment decisions. More importantly, group decisions in a gain situation appear to be more cautious, i.e., risk averse, than individual decisions, whereas group decisions in the loss situation appear to be more risky than individual decisions. Thus, group decision making may expand framing effects when it comes to investment choices through group polarization.

    Power laws describe the functional relationship between 2 quantities, such as the frequency of a group as the multiplicative power of group size. We examined whether the annual size of well-surveyed wintering populations of endangered Indiana bats (Myotis sodalis) followed a power law, and then leveraged this relationship to predict whether the aggregation of Indiana bats in winter was influenced by global climate processes. We determined that Indiana bat wintering populations were distributed according to a power law (mean scaling coefficient α = −0.44 [95% confidence interval {95% CI} = −0.61, −0.28). The antilog of these annual scaling coefficients ranged between 0.67 and 0.81, coincident with the three-fourths power found in many other biological phenomena. We associated temporal patterns in the annual (1983–2011) scaling coefficient with the North Atlantic Oscillation (NAO) index in August (βNAOAugust = −0.017 [90% CI = −0.032, −0.002]), when Indiana bats are deciding when and where to hibernate. After accounting for the strong effect of philopatry to habitual wintering locations, Indiana bats aggregated in larger wintering populations during periods of severe winter and in smaller populations in milder winters. The association with August values of the NAO indicates that bats anticipate future winter weather conditions when deciding where to roost, a heretofore unrecognized role for prehibernation swarming behavior. Future research is needed to understand whether the three-fourths–scaling patterns we observed are related to scaling in metabolism.

    2010-01-01

    Background Empirical support for cognitive behavioral therapy (CBT) for treating Japanese patients with major depression is lacking, therefore, a feasibility study of CBT for depression in Japanese clinical settings is urgently required. Findings A culturally adapted, 16-week manualized individual CBT program for Japanese patients with major depressive disorder was developed. A total of 27 patients with major depression were enrolled in a single-group study with the purpose of testing the feasibility of the program. Twenty six patients (96%) completed the study. The mean total score on the Beck Depression Inventory-II (BDI-II) for all patients (Intention-to-treat sample) improved from 32.6 to 11.7, with a mean change of 20.8 (95% confidence interval: 17.0 to 24.8). Within-group effect size at the endpoint assessment was 2.64 (Cohen's d). Twenty-one patients (77.7%) showed treatment response and 17 patients (63.0%) achieved remission at the end of the program. Significant improvement was observed in measurement of subjective and objective depression severity (assessed by BDI-II, Quick Inventory of Depressive Symptomatology-Self Rated, and Hamilton Depression Rating Scale), dysfunctional attitude (assessed by Dysfunctional Attitude Scale), global functioning (assessed by Global Assessment of Functioning of DSM-IV) and subjective well-being (assessed by WHO Subjective Well-being Inventory) (all p values < 0.001). Conclusions Our manualized treatment comprised of a 16-week individual CBT program for major depression appears feasible and may achieve favorable treatment outcomes among Japanese patients with major depression. Further research involving a larger sample in a randomized, controlled trial design is warranted. Trial registration UMIN-CTR UMIN000002542. PMID:20529252

    2013-09-01

    We characterized dusky dolphin (Lagenorhynchus obscurus) feeding behaviors recorded on underwater video, and related behaviors to variation in prey ball sizes, dolphin group sizes, and study site (Argentina versus New Zealand, NZ). Herding behaviors most often involved dolphins swimming around the side or under prey balls, but dolphins in Argentina more often swam under prey balls (48% of passes) than did dolphins in NZ (34% of passes). This result may have been due to differences in group sizes between sites, since groups are larger in Argentina. Additionally, in NZ, group size was positively correlated with proportion of passes that occurred under prey balls (pdolphins in Argentina more often swam through prey balls (8% of attempts) than did dolphins in NZ (4% of attempts). This result may have been due to differences in prey ball sizes between sites, since dolphins fed on larger prey balls in Argentina (>74m(2)) than in NZ (maximum 33m(2)). Additionally, in NZ, dolphins were more likely to swim through prey balls to capture fish when they fed on larger prey balls (p=0.025). Copyright © 2013 Elsevier B.V. All rights reserved.

  1. WORK GROUP DEVELOPMENT MODELS – THE EVOLUTION FROM SIMPLE GROUP TO EFFECTIVE TEAM

    Full Text Available Currently, work teams are increasingly studied by virtue of the advantages they have compared to the work groups. But a true team does not appear overnight but must complete several steps to overcome the initial stage of its existence as a group. The question that arises is at what point a simple group is turning into an effective team. Even though the development process of group into a team is not a linear process, the models found in the literature provides a rich framework for analyzing and identifying the features which group acquires over time till it become a team in the true sense of word. Thus, in this article we propose an analysis of the main models of group development in order to point out, even in a relative manner, the stage when the simple work group becomes an effective work team.

    Spambot detection in online social networks is a long-lasting challenge involving the study and design of detection techniques capable of efficiently identifying ever-evolving spammers. Recently, a new wave of social spambots has emerged, with advanced human-like characteristics that allow them...... to go undetected even by current state-of-the-art algorithms. In this paper, we show that efficient spambots detection can be achieved via an in-depth analysis of their collective behaviors exploiting the digital DNA technique for modeling the behaviors of social network users. Inspired by its...... biological counterpart, in the digital DNA representation the behavioral lifetime of a digital account is encoded in a sequence of characters. Then, we define a similarity measure for such digital DNA sequences. We build upon digital DNA and the similarity between groups of users to characterize both genuine...

    Breast cancer is the most common cancer in women. Surgical treatment of breast cancer may cause body image alterations. The purpose of the current study was to examine the effects of cognitive behavioral counseling on body image among Iranian women with primary breast cancer. In this quasi-experimental designed study, 72 patients diagnosed as breast cancer and surgically treated were enrolled in Isfahan, Iran. The patients were entered the study by convenience sampling method and were randomly divided in two groups of intervention (n = 32) and control (n = 40). The intervention group received consultation based on Ellis rational emotive behavior therapy (REBT) method for 6 sessions during 3 weeks. The control group did not receive any consultation Paired t-test was used to compare the changes in groups and independent t-test was conducted to compare two groups. The average values represented as mean ± standard deviation. Before the study, the body image score was not significantly different between the intervention (16 97 ± 5 44) and control (15 95 ± 4 66) groups (t = 0 86, P = 0 395). The body image score was significantly lower in the interven-tion group (9 03 ± 6 11) compared to control group (17 18 ± 5 27) after the intervention (t = -6 07, P influences her breast cancer treatment decision, oncology professionals need to recognize the value of a woman's favorite about appearance and body image.

    2017-01-01

    People's tendency to be more generous toward identifiable victims than toward unidentifiable or statistical victims is known as the Identifiable Victim Effect. Recent research has called the generality of this effect into question, showing that in cross-national contexts, identifiability mostly affects willingness to help victims of one's own "in-group." Furthermore, in inter-group conflict situations, identifiability increased generosity toward a member of the adversary group, but decreased generosity toward a member of one's own group. In the present research we examine the role of group-cohesiveness as an underlying factor accounting for these divergent findings. In particular, we examined novel groups generated in the lab, using the minimal group paradigm, as well as natural groups of students in regular exercise sections. Allocation decisions in dictator games revealed that a group's cohesiveness affects generosity toward in-group and out-group recipients differently, depending on their identifiability. In particular, in cohesive groups the identification of an in-group recipient decreased, rather than increased generosity.

    Social anxiety disorder (SAD) with comorbid avoidant personality disorder (APD) has a high prevalence and is associated with serious psychosocial problems and high societal costs. When patients suffer from both SAD and APD, the Dutch multidisciplinary guidelines for personality disorders advise offering prolonged cognitive behavioral therapy (CBT). Recently there is increasing evidence for the effectiveness of schema therapy (ST) for personality disorders such as borderline personality disorder and cluster C personality disorders. Since ST addresses underlying personality characteristics and maladaptive coping strategies developed in childhood, this treatment might be particularly effective for patients with SAD and comorbid APD. To our knowledge, there are no studies comparing CBT with ST in this particular group of patients. This superiority trial aims at comparing the effectiveness of these treatments. As an additional goal, predictors and underlying mechanisms of change will be explored. The design of the study is a multicentre two-group randomized controlled trial (RCT) in which the treatment effect of group cognitive behavioral therapy (GCBT) will be compared to that of group schema therapy (GST) in a semi-open group format. A total of 128 patients aged 18-65 years old will be enrolled. Patients will receive 30 sessions of GCBT or GST during a period of approximately 9 months. Primary outcome measures are the Liebowitz Social Anxiety Scale Self-Report (LSAS-SR) for social anxiety disorder and the newly developed Avoidant Personality Disorder Severity Index (AVPDSI) for avoidant personality disorder. Secondary outcome measures are the MINI section SAD, the SCID-II section APD, the Schema Mode Inventory (SMI-2), the Inventory of Depressive Symptomatology Self-Report (IDS-SR), the World Health Organization Quality of Life-BREF (WHOQOL-BREF), the Difficulties in Emotion Regulation Scale (DERS), the Rosenberg Self-Esteem Scale (RSES) and the Acceptance and Action

    Grebner, Dawn M.

    The scientific goal of this dissertation was to carefully study the signal structure of killer whale communications and vocal complexity and link them to behavioral circumstances. The overall objective of this research sought to provide insight into killer whale call content and usage which may be conveying information to conspecifics in order to maintain group cohesion. Data were collected in the summers of 2006 and 2007 in Johnstone Strait, British Columbia. For both individuals and small groups, vocalizations were isolated using a triangular hydrophone array and the behavioral movement patterns were captured by a theodolite and video camera positioned on a cliff overlooking the hyrophone locations. This dissertation is divided into four analysis chapters. In Chapter 3, discriminant analysis was used to validate the four N04 call subtypes which were originally parsed due to variations in slope segments. The first two functions of the discriminant analysis explained 97% of the variability. Most of the variability for the N04 call was found in the front convex and the terminal portions of the call, while very little variability was found in the center region of the call. This research revealed that individual killer whales produced multiple subtypes of the N04 call. No correlations of behaviors to acoustic parameters obtained were found. The aim of the Chapter 4 was to determine if killer whale calling behavior varied prior to and after the animals had joined. Pulsed call rates were found to be greater pre- compared to post-joining events. Two-way vocal exchanges were more common occurring 74% of the time during pre-joining events. In Chapter 5, initiated and first response to calls varied between age/sex class groups when mothers were separated from an offspring. Solo mothers and calves initiated pulsed calls more often than they responded. Most of the no vocal responses were due to mothers who were foraging. Finally, observations of the frequency split in N04

    To examine the influence of hypnotic suggestibility testing as a source of individual differences in hypnotic responsiveness, we compared behavioral and subjective responses on three scales of hypnotic suggestibility: The Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS: A; Shor, R. E., Orne, E. C. (1962). Harvard Group Scale of Hypnotic Susceptibility. Berlin: Consulting Psychologists Press); the Carleton University Responsiveness to Suggestion Scale (CURSS; Spanos, N. P., Radtke, H. L., Hodgins, D. C., Stam, H. J., Bertrand, L. D. (1983b). The Carleton University Responsiveness to Suggestion Scale: Normative data and psychometric properties. Psychological Reports, 53, 523-535); and the Group Scale of Hypnotic Ability (GSHA; Hawkins, R., Wenzel, L. (1999). The Group Scale of Hypnotic Ability and response booklet. Australian Journal of Clinical and Experimental Hypnosis, 27, 20-31). Behavioral and subjective responses to the CURSS were significantly different than those on the HGSHS: A and GSHA. More participants were classified as "low suggestible" on the CURSS and they reported subjective experiences more similar to everyday mentation. Attitudes and expectancies of participants who received the GSHA were less predictive of responding, but rates of responding and subjective experiences were similar on the GSHA and the HGSHS: A. Discussion focuses on implications for the use of group hypnotic suggestibility scales.

    Full Text Available Background: Post traumatic stress disorder (PTSD in war veterans has been linked with symptoms in their children, including symptoms resembling those of the traumatized parents, especially aggression. This study aims to examine the effectiveness of cognitive-behavioral group therapy in reducing aggressive behaviors of male adolescents whose fathers have war related PTSD. Method: 36 male children (aged 11 19 years whose fathers had PTSD, were randomly assigned into three groups for Rational-Emotive- Behavioral Therapy (REBT, Relaxation Therapy, and Wait-List control group. Each method had a course of ten therapeutic group sessions of 60 minutes once a week. Rates of aggression were assessed by Aggression Questionnaire (AGQ at baseline, end of intervention, and two months later. Results: The difference between AGQ scores of three groups was statistically significant. The behaviors of the three groups were not homogenous across the time (group × time interaction and showed a statistically significant difference. Conclusion: This study revealed that the intervention groups were superior to control group in reduction of aggressive behaviors in male adolescents of war veterans with PTSD. Further studies with greater sample size, prolonged duration of follow up, and multiple assessment procedures may be needed for better conclusions.

    Full Text Available Abstract Background The anesthetic drug ketamine (KT has been reported to be an abused drug and fatal cases have been observed in polydrug users. In the present study, considering the possibility of KT-enhanced toxic effects of other drugs, and KT-induced promotion of an overdose without making the subject aware of the danger due to the attenuation of several painful subjective symptoms, the intraperitoneal (i.p. KT-induced alterations in behaviors and toxic interactions with popular co-abused drugs, the psychostimulants cocaine (COC and methamphetamine (MA, were examined in ICR mice. Results A single dose of KT caused hyperlocomotion in a low (30 mg/kg, i.p. dose group, and hypolocomotion followed by hyperlocomotion in a high (100 mg/kg, i.p. dose group. However, no behavioral alterations derived from enhanced stress-related depression or anxiety were observed in the forced swimming or the elevated plus-maze test. A single non-fatal dose of COC (30 mg/kg, i.p. or MA (4 mg/kg, i.p. caused hyperlocomotion, stress-related depression in swimming behaviors in the forced swimming test, and anxiety-related behavioral changes (preference for closed arms in the elevated plus-maze test. For the COC (30 mg/kg or MA (4 mg/kg groups of mice simultaneously co-treated with KT, the psychostimulant-induced hyperlocomotion was suppressed by the high dose KT, and the psychostimulant-induced behavioral alterations in the above tests were reversed by both low and high doses of KT. For the toxic dose COC (70 mg/kg, i.p.- or MA (15 mg/kg, i.p.-only group, mortality and severe seizures were observed in some animals. In the toxic dose psychostimulant-KT groups, KT attenuated the severity of seizures dose-dependently. Nevertheless, the mortality rate was significantly increased by co-treatment with the high dose KT. Conclusion Our results demonstrated that, in spite of the absence of stress-related depressive and anxiety-related behavioral alterations following a single

    By applying nonequilibrium Green's function formalism combined with first-principles density functional theory, we investigate effect of torsion angle on electronic transport properties of 4,4 ' -biphenyl molecule connected with different anchoring groups (dithiocarboxylate and thiol group) to Au(111) electrodes. The influence of the HOMO-LUMO gaps and the spatial distributions of molecular orbitals on the quantum transport through the molecular device are discussed. Theoretical results show that the torsion angle plays important role in conducting behavior of molecular devices. By changing the torsion angle between two phenyl rings, namely changing the magnitude of the intermolecular coupling effect, a different transport behavior can be observed in these two systems.

    Full Text Available Substance use during sex is associated with sexual risk behavior among men who have sex with men (MSM, and MSM continue to be the group at highest risk for incident HIV in the United States. The objective of this study is to test the efficacy of a group-based, cognitive-behavioral intervention to reduce risk behavior of substance-using MSM, compared to a randomized attention-control group and a nonrandomized standard HIV-testing group.Participants (n = 1,686 were enrolled in Chicago, Los Angeles, New York City, and San Francisco and randomized to a cognitive-behavioral intervention or attention-control comparison. The nonrandomized group received standard HIV counseling and testing. Intervention group participants received six 2-h group sessions focused on reducing substance use and sexual risk behavior. Attention-control group participants received six 2-h group sessions of videos and discussion of MSM community issues unrelated to substance use, sexual risk, and HIV/AIDS. All three groups received HIV counseling and testing at baseline. The sample reported high-risk behavior during the past 3 mo prior to their baseline visit: 67% reported unprotected anal sex, and 77% reported substance use during their most recent anal sex encounter with a nonprimary partner. The three groups significantly (p0.05 from each other at 3-, 6-, and 12-mo follow-up. Outcomes for the 2-arm comparisons were not significantly different at 12-mo follow-up (e.g., unprotected anal sex, odds ratio = 1.14, confidence interval = 0.86-1.51, nor at earlier time points. Similar results were found for each outcome variable in both 2- and 3-arm comparisons.These results for reducing sexual risk behavior of substance-using MSM are consistent with results of intervention trials for other populations, which collectively suggest critical challenges for the field of HIV behavioral interventions. Several mechanisms may contribute to statistically indistinguishable reductions in risk

    Full Text Available Building relationships in the classroom is an essential part of any teacher's career. Having healthy teacher-to-learner and learner-to-learner relationships is an effective way to help prevent pedagogical failure, social conflict and quarrelsome behavior. Many strategies are available that can be used to achieve good long-lasting relationships in the classroom setting. Successful teachers’ pedagogical work in the classroom requires detailed knowledge of learners’ relationships. Good understanding of the relationships is necessary, especially in the case of teenagers’ class. This sensitive period of adolescence demands attention of all teachers who should deal with the problems of their learners. Special care should be focused on children that are out of their classmates’ interest (so called isolated learners or isolates in such class and on possibilities to integrate them into the class. Natural idea how to do it is that of using some modern non-traditional teaching/learning methods, especially the methods based on work in small groups involving learners’ cooperation. Small group education (especially problem-based learning, project-based learning, cooperative learning, collaborative learning or inquire-based learning as one of these methods involves a high degree of interaction. The effectiveness of learning groups is determined by the extent to which the interaction enables members to clarify their own understanding, build upon each other's contributions, sift out meanings, ask and answer questions. An influence of this kind of methods (especially cooperative learning (CL on learners’ relationships was a subject of the further described research. Within the small group education, students work with their classmates to solve complex and authentic problems that help develop content knowledge as well as problem-solving, reasoning, communication, and self-assessment skills. The aim of the research was to answer the question: Can the

    The aim of this study was to explore the effectiveness of Internet-delivered cognitive-behavioral therapy (iCBT) in treating fibromyalgia (FM) compared with an identical protocol using conventional group face-to-face CBT. Sixty participants were assigned to either (a) the waiting list group, (b) the CBT group, or (c) the iCBT group. The groups were assessed at baseline, after 10 weeks of treatment, and at 3-, 6-, and 12-month follow-ups. The primary outcome measured was the impact of FM on daily functioning, as measured by the Fibromyalgia Impact Questionnaire (FIQ). The secondary outcomes were psychological distress, depression, and cognitive variables, including self-efficacy, catastrophizing, and coping strategies. In post-treatment, only the CBT group showed improvement in the primary outcome. The CBT and iCBT groups both demonstrated improvement in psychological distress, depression, catastrophizing, and utilizing relaxation as a coping strategy. The iCBT group showed an improvement in self-efficacy that was not obtained in the CBT group. CBT and iCBT were dissimilar in efficacy at follow-up. The iCBT group members improved their post-treatment scores at their 6- and 12-month follow-ups. At the 12-month follow-up, the iCBT group showed improvement over their primary outcome and catastrophizing post-treatment scores. A similar effect of CBT was expected, but the positive results observed at the post-treatment assessment were not maintained at follow-up. The results suggest that some factors, such as self-efficacy or catastrophizing, could be enhanced by iCBT. Specific characteristics of iCBT may potentiate the social support needed to improve treatment adherence. Copyright © 2015 Elsevier Ltd. All rights reserved.

Galactic cosmic rays are composed of protons, α particles, and particles of high energy and charge (HZE particles). Research by our group has shown that exposure to HZE particles, primarily 600 MeV/n and 1 GeV/n 56Fe, can produce significant alterations in brain neurochemistry and behavior. However, given that protons can make up a significant portion of the radiation spectrum, it is important to study their effects on neural functioning and on related performance. Therefore, these studies examined the effects of exposure to proton irradiation on neurochemical and behavioral endpoints, including dopaminergic functioning, amphetamine-induced conditioned taste aversion learning, and spatial learning and memory as measured by the Morris water maze. Male Sprague-Dawley rats received a dose of 0, 1.5, 3.0 or 4.0 Gy of 250 MeV protons at Loma Linda University and were tested in the different behavioral tests at various times following exposure. Results showed that there was no effect of proton irradiation at any dose on any of the endpoints measured. Therefore, there is a contrast between the insignificant effects of high dose proton exposure and the dramatic effectiveness of low dose (<0.1 Gy) exposures to 56Fe particles on both neurochemical and behavioral endpoints.

    The neuroanatomical pathways of the DA systems have been shown to be largely conserved across many vertebrate taxa. It is less certain whether the structural similarities seen between mammals and amphibians reflect a similar functional homology. DA is well known for its role in facilitating motor behaviors in mammals. We examined whether a similar role for DA exists in amphibians using the Northern Leopard Frog (Rana pipiens). We investigated the effects of the nonspecific DA agonist, apomorp...

    The restoration of spontaneously broken CP invariance is investigated by using the effective QED lagrangian obtained from the standard SU(2) x U(1) gauge theory with two Higgs doublets. It is shown that the large electromagnetic field may restore CP invariance by changing the relative phase angle of Higgs vacuum expectation values even before one of the vacuum expectation values of the two Higgs doublets disappears. Further large magnetic field may lead to the fine structure constant with discontinuous behavior. (orig.)

    This study compared the efficacy of 2 psychological treatments for fibromyalgia with each other and with standard care. Ninety-three patients with fibromyalgia (FM) were randomly assigned to 1 of the 3 experimental conditions: 1) multicomponent cognitive-behavioral therapy (CBT); 2) multicomponent CBT with hypnosis; and 3) pharmacological treatment (standard care control group). The outcome measures of pain intensity, catastrophizing, psychological distress, functionality, and sleep disturbances were assessed before treatment, immediately after treatment, and at 3- and 6-month follow-up visits. CBT and CBT with hypnosis participants received the standard pharmacological management plus 14 weekly, 120-minute-long sessions of psychological treatment. All but 1 session followed a group format; the remaining session was individual. The analyses indicated that: 1) patients with FM who received multicomponent CBT alone or multicomponent CBT with hypnosis showed greater improvements than patients who received only standard care; and 2) adding hypnosis enhanced the effectiveness of multicomponent CBT. This study presents new evidence about the efficacy of multicomponent CBT for FM and about the additional effects of hypnosis as a complement to CBT. The relevance and implications of the obtained results are discussed. This article highlights the beneficial effects of adding hypnosis in a multicomponent cognitive-behavioral group treatment of fibromyalgia patients. Also, this research showed that by adding hypnosis the length of treatment did not increase. Copyright © 2012 American Pain Society. Published by Elsevier Inc. All rights reserved.

    For the purpose of the recovery of urokinase, the polypropylene (PP) films were modified by radiation-induced grafting of glycidylmethacrylate (GMA) and subsequent chemical modification of epoxy group of poly-GMA graft chains. The physical and chemical properties of the irradiated PP film, GMA-grafted PP film and the PP films modified with trimethylamine (TMA), hydroxylamine (HA), diethanolamine (DEA), and tri(hydroxymethyl)aminomethane (THMAM) were investigated by IR, SEM, and XPS. The adsorption of urokinase for the PP films modified with TMA, HA, DEA, and THMAM group were examined under various conditions of the functional group content, pH value and salt. It increased with increasing the content of functional group. The adsorption behavior of the PP films modified for different functional groups was in the following order: TMA>DEA>THMAM>HA. The adsorption of urokinase by the PP films with various functional groups at pH=7.4 were higher than that at pH=9.0. In TMA, DEA, and THMAM groups, the adsorption of urokinase without salts was also higher than those with salts. (author)

    We examined the interactive effects of leader group prototypicality, accountability, and team identification on team-oriented behavior of leaders, thus extending the social identity perspective on leadership to the study of leader behavior. An experimental study (N = 152) supported our hypothesis that leader accountability relates more strongly to team-oriented behavior for group nonprototypical leaders than for group prototypical leaders. A multisource field study with leaders (N = 64) and their followers (N = 209) indicated that this interactive effect is more pronounced for leaders who identify more strongly with their team. We discuss how these findings further develop the social identity analysis of leadership. PsycINFO Database Record (c) 2013 APA, all rights reserved.

    Full Text Available Unlike the typical stage-based policy commonly applied in Japan, the group-based control (often called movement-based in the traffic control industry in Japan refers to such a control pattern that the controller is capable of separately allocating time to each signal group instead of stage based on traffic demand. In order to investigate its applicability at signalized intersections in Japan, an intersection located in Yokkaichi City of Mie Prefecture was selected as an experimental application site by the Japan Universal Traffic Management Society (UTMS. Based on the data collected at the intersection before and after implementing the group-based control policy respectively, this study evaluated the impacts of such a policy on driver behavior and intersection safety. To specify those impacts, a few models utilizing cycle-based data were first developed to interpret the occurrence probability and rate of red-light-running (RLR. Furthermore, analyses were performed on the yellow-entry time (Ye of the last cleared vehicle and post encroachment time (PET during the phase switching. Conclusions supported that the group-based control policy, along with certain other factors, directly or indirectly influenced the RLR behavior of through and right-turn traffics. Meanwhile, it has potential safety benefits as well, indicated by the declined Ye and increased PET values.

    Full Text Available Abstract Background Coping with a chronic illness (CI challenges children's psychosocial functioning and wellbeing. Cognitive-behavioral intervention programs that focus on teaching the active use of coping strategies may prevent children with CI from developing psychosocial problems. Involvement of parents in the intervention program may enhance the use of learned coping strategies in daily life, especially on the long-term. The primary aim of the present study is to examine the effectiveness of a cognitive behavioral based group intervention (called 'Op Koers' 1 for children with CI and of a parallel intervention for their parents. A secondary objective is to investigate why and for whom this intervention works, in order to understand the underlying mechanisms of the intervention effect. Methods/design This study is a multicentre randomized controlled trial. Participants are children (8 to 18 years of age with a chronic illness, and their parents, recruited from seven participating hospitals in the Netherlands. Participants are randomly allocated to two intervention groups (the child intervention group and the child intervention combined with a parent program and a wait-list control group. Primary outcomes are child psychosocial functioning, wellbeing and child disease related coping skills. Secondary outcomes are child quality of life, child general coping skills, child self-perception, parental stress, quality of parent-child interaction, and parental perceived vulnerability. Outcomes are evaluated at baseline, after 6 weeks of treatment, and at a 6 and 12-month follow-up period. The analyses will be performed on the basis of an intention-to-treat population. Discussion This study evaluates the effectiveness of a group intervention improving psychosocial functioning in children with CI and their parents. If proven effective, the intervention will be implemented in clinical practice. Strengths and limitations of the study design are discussed

    Full Text Available Cognitive behavioral group therapy (CBGT is an effective, well-established, but not widely available treatment for social anxiety disorder (SAD. Internet-based cognitive behavior therapy (ICBT has the potential to increase availability and facilitate dissemination of therapeutic services for SAD. However, ICBT for SAD has not been directly compared with in-person treatments such as CBGT and few studies investigating ICBT have been conducted in clinical settings. Our aim was to investigate if ICBT is at least as effective as CBGT for SAD when treatments are delivered in a psychiatric setting.We conducted a randomized controlled non-inferiority trial with allocation to ICBT (n=64 or CBGT (n=62 with blinded assessment immediately following treatment and six months post-treatment. Participants were 126 individuals with SAD who received CBGT or ICBT for a duration of 15 weeks. The Liebowitz Social Anxiety Scale (LSAS was the main outcome measure. The following non-inferiority margin was set: following treatment, the lower bound of the 95 % confidence interval (CI of the mean difference between groups should be less than 10 LSAS-points.Both groups made large improvements. At follow-up, 41 (64% participants in the ICBT group were classified as responders (95% CI, 52%-76%. In the CBGT group, 28 participants (45% responded to the treatment (95% CI, 33%-58%. At post-treatment and follow-up respectively, the 95 % CI of the LSAS mean difference was 0.68-17.66 (Cohen's d between group=0.41 and -2.51-15.69 (Cohen's d between group=0.36 favoring ICBT, which was well within the non-inferiority margin. Mixed effects models analyses showed no significant interaction effect for LSAS, indicating similar improvement across treatments (F=1.58; df=2, 219; p=.21.ICBT delivered in a psychiatric setting can be as effective as CBGT in the treatment of SAD and could be used to increase availability to CBT.ClinicalTrials.gov NCT00564967.

    Full Text Available Oxytocin (OT is critical for lactation and maternal care, but OT and the related nonapeptide vasopressin are important for caregiving behaviors in fathers and alloparents as well. This experiment tested the effects of vasopressin and OT on food sharing in marmoset families. We treated caregivers (parents, siblings with intranasal vasopressin, OT, or saline, and then paired them with the youngest marmoset in the family. Caregivers were given preferred food, and then observed for food sharing and aggressive behavior with young marmosets. OT reduced food sharing from male alloparents to youngest siblings, and fathers that received vasopressin refused to share food with their youngest offspring more often than when treated with OT. Vasopressin increased aggressive vocalizations directed toward potential food recipients in all classes of caregivers. These results indicate that vasopressin and OT do not always enhance prosocial behavior: modulation of food sharing depends on both sex and parental status.

    To understand the current status of health literacy and the relationship between health literacy and health-promoting behaviors among multiethnic groups of women in Taiwan. Convenience and snowball sampling methods were used to recruit study participants. Data were collected using a cross-sectional questionnaire survey. We recruited community female adults who lived in greater Taipei or Taoyuan areas (northern Taiwan) from January 1, 2010 through June 30, 2011. A total of 378 female participants were contacted, of which 351 consented to participate and 347 completed valid questionnaires for analysis. Health literacy was measured with the Taiwan Health Literacy Scale, and health-promoting behaviors were measured by the Chinese version of the Health-Promoting Lifestyle Profile. Participants had a moderate level of health literacy, and one third of them had inadequate health literacy. Participants with inadequate health literacy were more likely to be younger, not a high school graduate, and Vietnamese; to have a low monthly family income and no diagnosed diseases; to use a second language; and to regard TV/radio as the most useful source of health information. Health literacy alone could significantly predict health-promoting behaviors among the participants. Our findings confirmed that low health literacy is prevalent among underprivileged women in Taiwan. Health-related programs that are literacy sensitive and culturally appropriate are needed to teach and encourage health-promoting behaviors. © 2013 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

    In this paper, absorption and fluorescence spectra of vitamin B12 (cyanocobalamin) and vitamin B6 (pyridoxine) were recorded in solvents with different polarity, at room temperature. These vitamins' photo-physical behavior depends strongly on the solvent's nature along with different attached groups in their structures. In order to investigate the solvent-solute interactions and environmental effect on spectral variations, linear solvation energy relationships concept, suggested by Kamlet and Taft was used. Solvatochromic method was also used for measuring the ground and excited state dipole moments of these vitamins. According to our experimental results, dipole moment of these groups of vitamins in excited state is larger than ground state. Furthermore, obtained photo-physical and interactional properties of used vitamins can give important information on how this group of vitamins behaves in biological systems.

    Co-morbid anxiety and depression in older adults is associated with worse physical and mental health outcomes and poorer response to psychological and pharmacological treatments in older adults. However, there is a paucity of research focused on testing the efficacy of the co-morbid treatment of anxiety and depression in older adults using psychological interventions. Accordingly, the primary objective of the current study was to test the effects of a group cognitive behavior therapy (CBT) program in treating co-morbid anxiety and depression in a sample of older age adults. A total of 133 community-dwelling participants aged ⩾60 years (mean age = 67.35, s.d. = 5.44, male = 59) with both an anxiety disorder and unipolar mood disorder, as assessed on the Anxiety Disorder Interview Schedule (ADIS), were randomly allocated to an 11-week CBT group or discussion group. Participants with Mini-Mental State Examination scores <26 were excluded. Participants were assessed pre-treatment, post-treatment and at 6 months follow-up on the ADIS, a brief measure of well-being, Geriatric Anxiety Inventory and Geriatric Depression Scale. Both conditions resulted in significant improvements over time on all diagnostic, symptom and wellbeing measures. Significant group × time interaction effects emerged at post-treatment only for diagnostic severity of the primary disorder, mean severity of all anxiety disorders, mood disorders, and all disorders, and recovery rates on primary disorder. Group CBT produced faster and sustained improvements in anxiety and depression on diagnostic severity and recovery rates compared to an active control in older adults.

  20. Acute and Developmental Behavioral Effects of Flame ...

    Science.gov (United States)

    As polybrominated diphenyl ethers are phased out, numerous compounds are emerging as potential replacement flame retardants for use in consumer and electronic products. Little is known, however, about the neurobehavioral toxicity of these replacements. This study evaluated the neurobehavioral effects of acute or developmental exposure to t-butylphenyl diphenyl phosphate (BPDP), 2-ethylhexyl diphenyl phosphate (EHDP), isodecyl diphenyl phosphate (IDDP), isopropylated phenyl phosphate (IPP), tricresyl phosphate (TMPP; also abbreviated TCP), triphenyl phosphate (TPHP; also abbreviated TPP), tetrabromobisphenol A (TBBPA), tris (2-chloroethyl) phosphate (TCEP), tris (1,3-dichloroisopropyl) phosphate (TDCIPP; also abbreviated TDCPP), tri-o-cresyl phosphate (TOCP), and 2,2-,4,4’-tetrabromodiphenyl ether (BDE-47) in zebrafish (Danio rerio) larvae. Larvae (n≈24 per dose per compound) were exposed to test compounds (0.4 - 120 µM) at sub-teratogenic concentrations either developmentally or acutely, and locomotor activity was assessed at 6 days post fertilization. When given developmentally, all chemicals except BPDP, IDDP and TBBPA produced behavioral effects. When given acutely, all chemicals produced behavioral effects, with TPHP, TBBPA, EHDP, IPP, and BPDP eliciting the most effects at the most concentrations. The results indicate that these replacement flame retardants may have developmental or pharmacological effects on the vertebrate nervous system. This study

    Drab, Deborah D.

    Grouping students for labs in science classes is a common practice. This mixed methods quasi-experimental action research study examines homogeneous and heterogeneous gender grouping strategies to determine what gender grouping strategy is the most effective in a coeducational science classroom setting. Sixth grade students were grouped in same-gender and mixed-gender groups, alternating each quarter. Over the course of an academic year, data were collected from four sources. The teacher-researcher observed groups working during hands-on activities to collect data on student behaviors. Students completed post-lab questionnaires and an end-of-course questionnaire about their preferences and experiences in the different grouping strategies. Student scores on written lab assignments were also utilized. Data analysis focused on four areas: active engagement, student achievement, student perceptions of success and cooperative teamwork. Findings suggest that teachers may consider grouping students of different ability levels according to different gender grouping strategies to optimize learning.

    Full Text Available Introduction: the arthritis is believed to be among common diseases which prevail in the developed and developing countries, including Iran. In demographic studies, the prevalence of knee arthritis which stands at %15/3 in the population above 15-years old was shown. Owing to the fact that societies are about to be aged than before, the issue has become a growing significance in the subject matter of public health. The present study is conducted with an aim to investigate into the effect of training based on the planned behavior model on preventing the teachers of preliminary schools from getting knee arthritis. Methods: the study as an intervention research is of quasi-experimental kind. The population in question included 114 individuals among female teachers of preliminary schools who were brought to the study randomly and divided into two groups intervention and non-intervention. Based on the primary results, the educational contents were designed and submitted in the intervention group. After two months of executing the training program, the post test was carried out. The data was analyzed by SPSS version 18. Due to the loss of normality in data distribution, non- parametric tests were used. Results: the study demonstrated that the components of the planned behavior theory (i.e. the attitudes, subjective norms and the control of perceived behavior could altogether estimate %37 of intention and %43 of behavior. Meanwhile, the role of subjective norms (β =56/0 in predicting intention was overriding, In this study,after the educational program, control of perceived behavior scores increased of 32/50 ± 4/05 to 34/82 ± 5/66. indicating that the major obstacles in adopting behaviors preventing from knee arthritis are the lack of regular physical activity (%72/4 and failure to use western-style toilet (%57.

    The interactions between cancer cells and the extracellular matrix (ECM) are important with respect to a number of cell behavoirs, yet remain unclear. In this study, self-assembled monolayers with different terminal chemical groups (hydroxyl (-OH), carboxyl (-COOH), animo (-NH 2 ), mercapto (-SH), and methyl (-CH 3 )) were employed as substrates for the culture of MCF-7 cells to examine effects on cell behavior. Cell spreading was investigated by scanning electron microscopy, tallin expression by immunofluorescence, proliferation rate by counting cell numbers, cell cycle by flow cytometry, metabolism by high-performance liquid chromatography and cell migration by live cell imaging. Annexin V-FITC (fluorescein isothiocyanate) and JC-1 assays were performed to determine cell apoptosis and mitochondrial membrane potential, respectively. Our results demonstrate the varied behaviors of MCF-7 cells in response to different chemical groups. Specifically, NH 2 and COOH terminal functional groups promote proliferation, the production of lactic acid and mobility of MCF-7 cells; SH and OH terminal groups enhance the expression and distribution of tallin but result in weak cell proliferation, metabolism, spreading and mobility. These results are meaningful for uncovering the interactions between the ECM and cancer cells; they are potentially useful for designing novel cancer treatment strategies. (paper)

    Full Text Available Introduction: With industrialization of human societies, pollutants like lead have entered in the life cycle, causing harmful effects on body organs. No sufficient studies have been done on the effects of pollutants on behavior. The aim of this study was to investigate possible effects of lead on some measurable behaviors of an animal model. Methods: Forty eight male adult mice were divided into 4 groups of 12 each. Lead acetate was added at concentrations of 0, 5, 50, or 500 ppm to the drinking water of the animals for 4 weeks (28 days. On day 29, animals were placed on an Elevated Plus maze (EPM for 5 min and the time in sec spent was measured on closed arms, open arms and the end 1/3rd of the open arms. Increased time on open arms, particularly the end 1/3rd was considered to reflect an enhanced risk-accepting behavior. Results: In this study, it was shown that lead exposure caused an increased number of entrance (P=0.006 and time spent (P=0.034 by mice on open arms of the EPM. There was a positive correlation between the concentration of lead acetate and those two effects. Conclusion: The present study demonstrated that lead poisoning may decrease normal anxiety in mice and increase risky behavior in this species. Clinical studies on human subjects with risky behavior are strongly suggested in order to find a possible relation between chronic exposures to lead as well as plasma concentration of lead with the extent of this kind of behavior.

    Nonhuman primates display an interest in novel places, habituate to new situations, and spend most of their daily activity in the wild in large groups engaging in feeding behaviors. Captivity changes these behaviors, and disrupts normal social hierarchies. In captivity, animals may exhibit stereotypical behaviors which are thought to indicate decreased psychological well-being (PWB). If an animal's behaviors can be made to approach those seen in the wild, and stereotypical behaviors are minimal it is assumed that PWB is adequate. Environmental enrichment (EE) devices have been used to address the Animal Welfare Act's requirement that the PWB of captive nonhuman primates be considered. The purpose of the present study was to examine whether various EE devices improve the PWB of captive squirrel monkeys. The present study used behavioral observation to quantify the effectiveness of several EE devices in reducing stereotypical behaviors in squirrel monkeys housed singly or in groups. Results showed that the EE devices used did not affect the expression of normal or stereotypical behaviors, but that the type of housing did.

    Background and aims Binge-watching (i.e., seeing multiple episodes of the same TV series in a row) now constitutes a widespread phenomenon. However, little is known about the psychological factors underlying this behavior, as reflected by the paucity of available studies, most merely focusing on its potential harmfulness by applying the classic criteria used for other addictive disorders without exploring the uniqueness of binge-watching. This study thus aimed to take the opposite approach as a first step toward a genuine understanding of binge-watching behaviors through a qualitative analysis of the phenomenological characteristics of TV series watching. Methods A focus group of regular TV series viewers (N = 7) was established to explore a wide range of aspects related to TV series watching (e.g., motives, viewing practices, and related behaviors). Results A content analysis identified binge-watching features across three dimensions: TV series watching motivations, TV series watching engagement, and structural characteristics of TV shows. Most participants acknowledged that TV series watching can become addictive, but they all agreed having trouble recognizing themselves as truly being an "addict." Although obvious connections could be established with substance addiction criteria and symptoms, such parallelism appeared to be insufficient, as several distinctive facets emerged (e.g., positive view, transient overinvolvement, context dependency, and low everyday life impact). Discussion and conclusion The research should go beyond the classic biomedical and psychological models of addictive behaviors to account for binge-watching in order to explore its specificities and generate the first steps toward an adequate theoretical rationale for these emerging problematic behaviors.

    Although wild primates are known to modify behavior in response to thermal stress, less is known about behavioral thermoregulation in zoo-housed primates. Zoo exhibits expose individuals to unique thermal environments and may constrain the thermoregulatory strategies available to individual animals. In this study, we observed a group of seven colobus monkeys (Colobus guereza) living on a concrete "Monkey Island" style exhibit that featured limited shade and limited arboreal space. Behaviors were recorded using continuous focal animal sampling (n = 63 days, 97.7 hr). Logistic regression revealed 23°C was the temperature at which monkeys began resting more in shade than in sun. When temperatures exceeded 23°C, animals spent more time in open sitting postures with limbs extended from the body; sat less frequently in closed, hunched postures; spent more time in social contact; and performed more self-directed behaviors. Exhibit use also shifted under higher temperatures, with more time spent in areas with shade and lower surface temperatures. Lastly, when provided with access to an indoor holding area, the colobus monkeys spent more than half the time indoors when temperatures exceeded 23°C, yet only 10% of their time indoors when the temperature was below this value. Although postural changes have been reported in wild colobus, the postural and other behavioral changes observed in the current study occurred at temperatures lower than expected based on the published thermoneutral zone of colobus monkeys and highlight the importance of considering the specific thermoregulatory responses of zoo animals. © 2014 Wiley Periodicals, Inc.

    The present study evaluated the effects of mixed opioid drugs on the severity of cocaine (COCA) toxicity by examining stress-related behavioral alterations in mice. In order to ascertain the strength of the stress, the continuous observation of the behavioral symptoms in the cage and the forced swimming test (Porsolt test) were performed in the COCA (75 mg/kg, i.p.)-treated groups, with or without the mixed mu-kappa receptor-related opioid drugs, buprenorphine (BUP) and pentazocine (PEN). Using the high-sensitivity activity measuring instrument Supermex, both the spontaneous behaviors in the cage and the forced swimming behaviors in the water were assessed as activity counts. The behavioral alterations in the COCA-treated groups were compared with a group of mice given a 10 min immobilization stress (IM group). In the COCA-only group, a prolonged increase in the spontaneous behaviors accompanied by convulsive seizures was observed even in the surviving mice, unlike in the IM group. However, an acceleration of behavioral despair in the Porsolt test similar to that observed in the IM group was observed in the COCA group after the disappearance of the acute toxic symptoms (5 hours after the COCA treatment). Among the opioid-treated groups, the mortality rate was attenuated only in the COCA-BUP (0.25 mg/kg, i.p.) group. In the COCA-BUP group, a prolonged suppression of the morbid hyperactivity in the cage except for the convulsive seizures, and a normalization of the swimming behavior in the Porsolt test were observed in the survivors. On the other hand, in the COCA-PEN (5 mg/kg, i.p.) group, the swimming behavior in the Porsolt test was abnormally increased in addition to the prolonged morbid hyperactivity in the cage. Therefore, the COCA-induced stress-related behaviors were normalized in the group of mice treated with BUP, a group with a good prognosis.

    The pathogenesis of bacterial vaginosis (BV) remains elusive. BV may be more common among women who have sex with women (WSW). The objective of this study was to use 454 pyrosequencing to investigate the vaginal microbiome of WSW, women who have sex with women and men (WSWM), and women who have sex with men (WSM) with BV to determine if there are differences in organism composition between groups that may inform new hypotheses regarding the pathogenesis of BV. Vaginal swab specimens from eligible women with BV at the Mississippi State Department of Health STD Clinic were used. After DNA extraction, 454 pyrosequencing of PCR-amplified 16S rRNA gene sequences was performed. Sequence data was classified using the Ribosomal Database Program classifer. Complete linkage clustering analysis was performed to compare bacterial community composition among samples. Differences in operational taxonomic units with an abundance of ≥ 2% between risk behavior groups were determined. Alpha and beta diversity were measured using Shannon's Index implemented in QIIME and Unifrac analysis, respectively. 33 WSW, 35 WSWM, and 44 WSM were included. The vaginal bacterial communities of all women clustered into four taxonomic groups with the dominant taxonomic group in each being Lactobacillus, Lachnospiraceae, Prevotella, and Sneathia. Regarding differences in organism composition between risk behavior groups, the abundance of Atopobium (relative ratio (RR)=0.24; 95%CI 0.11-0.54) and Parvimonas (RR=0.33; 95%CI 0.11-0.93) were significantly lower in WSW than WSM, the abundance of Prevotella was significantly higher in WSW than WSWM (RR=1.77; 95%CI 1.10-2.86), and the abundance of Atopobium (RR=0.41; 95%CI 0.18-0.88) was significantly lower in WSWM than WSM. Overall, WSM had the highest diversity of bacterial taxa. The microbiology of BV among women in different risk behavior groups is heterogeneous. WSM in this study had the highest diversity of bacterial taxa. Additional studies are

    The current study investigates sudden gains (rapid symptom reduction) in group cognitive-behavioral therapy for panic disorder. Sudden gains occurring after session 2 of treatment predicted overall symptom reduction at treatment termination and some changes in cognitive biases. Meanwhile, sudden gains occurring immediately following session 1 were not associated with symptom reduction or cognitive change. Together, this research points to the importance of examining sudden gains across the entire span of treatment, as well as the potential role of sudden gains in recovery from panic disorder.

    Full Text Available Background and Objective: Breastfeeding is a matter of significant importance. Given the role of such factors as attitude and subjective norms on the behavior of mothers and the low level of exclusive breastfeeding, the present study aimed to determine the effect of educational program based on the theory of planned behavior on breastfeeding behavior among the pregnant women in Fasa, Iran. Materials and Methods: This quasi-experimental study was conducted on 100 pregnant women with the gestational age of 30-35 weeks who referred to the health care centers of Fasa, Iran, in 2017. The study population was selected using random sampling technique, and then assigned into two groups of control (n=50 and intervention (n=50. The data were collected using a demographic form, components of the theory of planned behavior questionnaire, and a breastfeeding checklist. The intervention group received three 55-to-60-minute training sessions. The mothers' breastfeeding behavior was evaluated before the training sessions and 40 days post-delivery in both groups. The data were analyzed in SPSS software, version 22, using Chi-square test, independent t-test, and paired sample t-test. Results: According to the results, there was no significant difference between the two groups in terms of the components of the theory of planned behavior before the educational intervention (P=0.208. However, after the training sessions, the intervention group showed a significant improvement in all components of the theory of planned behavior, including intention and breastfeeding behavior, compared to the control group (P=0.001. Conclusion: Based on the findings of this study, appropriate training programs, social network support, and suitable conditions for breastfeeding in the community are among the effective factors that can change the mothers’ attitudes towards lactation and result in successful breastfeeding in the first three months after childbirth.

    Intersexual social segregation at small spatial scales is prevalent in ruminants that are sexually dimorphic in body size. Explaining social segregation, however, from hypotheses of how intersexual size differences affects the foraging process of males and females has had mixed results. We studied whether body size influences on forage behavior, intersexual social incompatibility or both might influence social segregation in a population of Roosevelt elk (Cervus elaphus roosevelt) that declined 40% over 5 y. Most males and females in the population occurred in the same forage patches, meadows, but occupied different parts of meadows and most groups were overwhelming comprised of one sex. The extent of segregation varied slightly with changing elk density. Cropping rate, our surrogate of forage ingestion, of males in mixed-sex groups differed from males in male-only groups at high, but not low, elk density. In a prior study of intersexual social interactions it was shown that females avoided groups containing ???6 males. Therefore, we predicted that females should avoid parts of meadows where groups of males ???6 were prevalent. Across the 5 y of study this prediction held because ???5% of all females were found in parts of meadows where median aggregation sizes of males were ???6. Social segregation was coupled to body size influences on forage ingestion at high density and social incompatibility was coupled to social segregation regardless of elk density.

    The neuroanatomical pathways of the DA systems have been shown to be largely conserved across many vertebrate taxa. It is less certain whether the structural similarities seen between mammals and amphibians reflect a similar functional homology. DA is well known for its role in facilitating motor behaviors in mammals. We examined whether a similar role for DA exists in amphibians using the Northern Leopard Frog (Rana pipiens). We investigated the effects of the nonspecific DA agonist, apomorphine (APO) on a complex motor task that included two distinct components known to be differentially modulated by DA in mammals: swimming and climbing. We demonstrated that a high single dose of APO (20 mg/kg, body weight) strongly increased the amount of time spent completing the motor task. Furthermore, we showed that although APO did not significantly alter several aspects of swimming behavior, two aspects of climbing behavior were disrupted. Both climbing speed and climbing ability were impaired by APO treatment. These results increase our understanding of DA function in amphibians and add to our understanding of structure-function homologies of dopamine function across vertebrate taxa.

    To quantify empirically the role of peer social networks in contraceptive behavior among adolescents. Using longitudinal data from a nationally representative sample of adolescents, the authors use a multivariate structural model with school-level fixed effects to account for the problems of contextual effects, correlated effects, and peer selection to reduce the potential impact of biases from the estimates of peer influence. The peer group measures are drawn not only from the nominations of close friends but also from classmates. Contraception use among the peer groups was constructed using the peers' own reports of their contraceptive behavior. Controlling for parental characteristics and other demographic variables, the authors find that a 10% increase in the proportion of classmates who use contraception increases the likelihood of individual contraception use by approximately 5%. They also find evidence that the influence of close friends diminishes after accounting for unobserved environmental confounders. The findings of this study support the findings in the literature that peer effects are important determinants of contraception use even after controlling for potential biases in the data. Effective policy aimed at increasing contraception use among adolescents should consider these peer effects.

  20. Reducing Societal Obesity: Establishing a Separate Exercise Model through Studies of Group Behavior.

    2016-01-01

    The past 50 years has brought attention to high and increasing levels of human obesity in most of the industrialized world. The medical profession has noticed, has evaluated, and has developed models for studying, preventing, and reversing obesity. The current model prescribes activity in specific quantities such as days, minutes, heart rates, and footfalls. Although decreased levels of activity have come from changes revolving around built environments and social networks, the existing medical model to lower body weights by increasing activity remains individually prescriptive. It is not working. The study of societal obesity precludes the individual and must involve group behavioral studies. Such studies necessitate acquiring separate tools and, therefore, require a significant change in the evaluation and treatment of obesity. Finding groups with common activities and lower levels of obesity would allow the development of new models of land use and encourage active lifestyles through shared interests.

    This article reports the results of a preliminary research project that explored the relationship between assertiveness, cognitive development and contraceptive behavior among single young women in their freshman and senior years at college. A total of 60 college women at a university health center volunteered to participate in this pilot study. They filled out three instruments: the Galassi College Self-Expression Scale (SES), the Measure of Intellectual Development (MID) tool and an author-developed sexuality questionnaire. Although there was a significant relationship between cognitive development and assertiveness, no significant relationships were found between cognitive development, assertiveness and use of effective contraception. Interesting descriptive characteristics were identified. Clinical implications are discussed.

    We investigate how two important social identities--gender identity and moral identity--result in differential donations to in-groups and out-groups. Results from three studies indicate that moral identity importance tends to increase donations to out-groups (Iraq, Indonesia) and not to in-groups (London, New Orleans). However, this occurs only for consumers with a feminine gender identity. For consumers with a masculine gender identity, moral identity importance increases donations to the in...

    In his seminal works on group dynamics Bion defined a specific therapeutic setting allowing psychoanalytic observations on group phenomena. In describing the setting he proposed that the group was where his voice arrived. This physical limit was later made operative by assuming that the natural dimension of a therapeutic group is around 12 people. Bion introduced a theory of the group aspects of the mind in which proto-mental individual states spontaneously evolve into shared psychological states that are characterized by a series of features: (1) they emerge as a consequence of the natural tendency of (both conscious and unconscious) emotions to combine into structured group patterns; (2) they have a certain degree of stability in time; (3) they tend to alternate so that the dissolution of one is rapidly followed by the emergence of another; (4) they can be described in qualitative terms according to the nature of the emotional mix that dominates the state, in structural terms by a kind of typical "leadership" pattern, and in "cognitive" terms by a set of implicit expectations that are helpful in explaining the group behavior (i.e., the group behaves "as if" it was assuming that). Here we adopt a formal approach derived from Socio-physics in order to explore some of the structural and dynamic properties of this small group dynamics. We will described data from an analytic DS model simulating small group interactions of agents endowed with a very simplified emotional and cognitive dynamic in order to assess the following main points: (1) are metastable collective states allowed to emerge in the model and if so, under which conditions in the parameter space? (2) can these states be differentiated in structural terms? (3) to what extent are the emergent dynamic features of the systems dependent of the system size? We will finally discuss possible future applications of the quantitative descriptions of the interaction structure in the small group clinical setting.

    Supported employment programs are highly effective in helping people with severe mental illness obtain competitive jobs quickly. However, job tenure is often a problem for many. Of the various obstacles to job tenure documented, dysfunctional beliefs regarding the workplace and one's own abilities has been proposed as a therapeutic target. The purpose of this article is threefold: (1) to describe the development and the content of a novel group cognitive behavioral intervention designed to increase job tenure for people receiving supported employment services; (2) to present the feasibility and acceptability of the intervention; and (3) to investigate some preliminary data regarding employment outcomes. A group CBT intervention offered during 8 sessions over the course of one month, in order to respect the rapid job search principle of IPS (individual placement and support), was developed. The content was tailored to facilitate the learning of skills specific to the workplace, such as recognizing and managing one's stressors at work, determining and modifying dysfunctional thoughts (e.g. not jumping to conclusions, finding alternatives, seeking facts), overcoming obstacles (e.g. problem solving), improving one's self-esteem as a worker (recognizing strengths and qualities), dealing with criticism, using positive assertiveness, finding coping strategies (for symptoms and stress) to use at work, negotiating work accommodations and overcoming stigma. A trial is currently underway, with half the participants receiving supported employment as well as CBT-SE and the other half receiving only supported employment. A subsample of the first 24 participants having completed the 12-month follow-up were used for the analyses, including 12 having received at least 3 sessions out of the 8 group sessions and 12 receiving only supported employment. Feasibility and acceptability were determined by the group therapists' feedback, the participants' feedback as well as attendance to

    The present study analyzes the association between the motivation to change and the cognitive-behavioral group intervention, in terms of dropouts and relapses, in a sample of male pathological gamblers. The specific objectives were as follows: (a) to estimate the predictive value of baseline University of Rhode Island Change Assessment scale (URICA) scores (i.e., at the start of the study) as regards the risk of relapse and dropout during treatment and (b) to assess the incremental predictive ability of URICA scores, as regards the mean change produced in the clinical status of patients between the start and finish of treatment. The relationship between the URICA and the response to treatment was analyzed by means of a pre-post design applied to a sample of 191 patients who were consecutively receiving cognitive-behavioral group therapy. The statistical analysis included logistic regression models and hierarchical multiple linear regression models. The discriminative ability of the models including the four URICA scores regarding the likelihood of relapse and dropout was acceptable (area under the receiver operating haracteristic curve: .73 and .71, respectively). No significant predictive ability was found as regards the differences between baseline and posttreatment scores (changes in R(2) below 5% in the multiple regression models). The availability of useful measures of motivation to change would enable treatment outcomes to be optimized through the application of specific therapeutic interventions. © 2012 Wiley Periodicals, Inc.

    ADHD affects between 2% and 8% of college students and is associated with broad functional impairment. No prior randomized controlled trials with this population have been published. The present study is a pilot randomized controlled trial evaluating dialectical behavior therapy (DBT) group skills training adapted for college students with ADHD. Thirty-three undergraduates with ADHD between ages 18 and 24 were randomized to receive either DBT group skills training or skills handouts during an 8-week intervention phase. ADHD symptoms, executive functioning (EF), and related outcomes were assessed at baseline, post-treatment, and 3-month follow-up. Participants receiving DBT group skills training showed greater treatment response rates (59-65% vs. 19-25%) and clinical recovery rates (53-59% vs. 6-13%) on ADHD symptoms and EF, and greater improvements in quality of life. DBT group skills training may be efficacious, acceptable, and feasible for treating ADHD among college students. A larger randomized trial is needed for further evaluation. © 2014 SAGE Publications.

However, this group is continuously experiencing health problems for example, depression is one of their major problems. The aim of the present study is to determine the effect of group reminiscence therapy on depression of elderly resident of Shahrekord, Iran. Methods and Materials: This is a clinical trial study. The sample was consisted of 64 elderly referring to retirement centre in Shahrekord in 1385 that were selected by convenience sampling, and then divided randomly into two groups: an experimental and a control group. Group reminiscence meetings for experimental group and group meetings for control group were formed each 8 session for one hour and a half. Depression level of investigated subjects’ pre and post intervention were assessed with the use of Geriatric Depression Scale. Descriptive and conceptual statistics were used for data analysis (Chi-square Test, mean - standard deviation- Paired t-test. Results: Findings of this study showed a significant difference between pre and post intervention, where the elderly depression mean score in experimental group changed from 17.95 to 12.99 (p=0.04 but no significant difference were observed in the control group. Conclusion: Considering the result of this study, it can be suggested that group reminiscence therapy is effective on the reduction of elderly depression level. Therefore, we can use this forgotten, easy and practicable and cheap technique in all nursing-homes and even at home.

    Lysergic acid diethylamide (LSD) is a potent hallucinogenic drug that strongly affects animal and human behavior. Although adult zebrafish (Danio rerio) are emerging as a promising neurobehavioral model, the effects of LSD on zebrafish have not been investigated previously. Several behavioral paradigms (the novel tank, observation cylinder, light-dark box, open field, T-maze, social preference and shoaling tests), as well as modern video-tracking tools and whole-body cortisol assay were used to characterize the effects of acute LSD in zebrafish. While lower doses (5-100 microg/L) did not affect zebrafish behavior, 250 microg/L LSD increased top dwelling and reduced freezing in the novel tank and observation cylinder tests, also affecting spatiotemporal patterns of activity (as assessed by 3D reconstruction of zebrafish traces and ethograms). LSD evoked mild thigmotaxis in the open field test, increased light behavior in the light-dark test, reduced the number of arm entries and freezing in the T-maze and social preference test, without affecting social preference. In contrast, LSD affected zebrafish shoaling (increasing the inter-fish distance in a group), and elevated whole-body cortisol levels.

    This study explored the prevalence of risk behaviors (excessive alcohol use, illegal drug use, heavy smoking, reduced sleep, overweight, underweight, sedentary behavior, high use of Internet/TV/videogames for reasons not related to school or work, and truancy), and their association with psychopathology and self-destructive behaviors, in a sample of 12,395 adolescents recruited in randomly selected schools across 11 European countries. Latent class analysis identified three groups of adolescents: a low-risk group (57.8%) including pupils with low or very low frequency of risk behaviors; a high-risk group (13.2%) including pupils who scored high on all risk behaviors, and a third group ("invisible" risk, 29%) including pupils who were positive for high use of Internet/TV/videogames for reasons not related to school or work, sedentary behavior and reduced sleep. Pupils in the "invisible" risk group, compared with the high-risk group, had a similar prevalence of suicidal thoughts (42.2% vs. 44%), anxiety (8% vs. 9.2%), subthreshold depression (33.2% vs. 34%) and depression (13.4% vs. 14.7%). The prevalence of suicide attempts was 5.9% in the "invisible" group, 10.1% in the high-risk group and 1.7% in the low-risk group. The prevalence of all risk behaviors increased with age and most of them were significantly more frequent among boys. Girls were significantly more likely to experience internalizing (emotional) psychiatric symptoms. The "invisible" group may represent an important new intervention target group for potentially reducing psychopathology and other untoward outcomes in adolescence, including suicidal behavior.

    Full Text Available Background: Breast cancer is the most common cancer in women. Surgical treatment of breast cancer may cause body image alterations. The purpose of the current study was to examine the effects of cognitive behavioral counseling on body image among Iranian women with primary breast cancer. Methods: In this quasi-experimental designed study, 72 patients diagnosed as breast cancer and surgically treated were enrolled in Isfahan, Iran. The patients were entered the study by convenience sampling method and were randomly di-vided in two groups of intervention (n = 32 and control (n = 40. The intervention group received consultation based on Ellis rational emotive behavior therapy (REBT method for 6 sessions during 3 weeks. The control group did not re-ceive any consultation Paired t-test was used to compare the changes in groups and independent t-test was conducted to compare two groups. The average values represented as mean ± standard deviation. Results: Before the study, the body image score was not significantly different between the intervention (16 97 ± 5 44 and control (15 95 ± 4 66 groups (t = 0 86, P = 0 395. The body image score was significantly lower in the interven-tion group (9 03 ± 6 11 compared to control group (17 18 ± 5 27 after the intervention (t = -6 07, P < 0 001. Conclusions: Since a woman′s body image influences her breast cancer treatment decision, oncology professionals need to recognize the value of a woman′s favorite about appearance and body image. This study emphasizes the impor-tance of offering consultation in breast cancer patients.

    2016-01-01

    The purpose of this paper is to present the results of exploratory research designed to develop an awareness of healthcare behaviors, with a view toward improving the customer satisfaction with healthcare services. It examines the relationship between healthcare providers and their consumers/patients/clients. The study uses a critical incident methodology, with both effective and ineffective behavioral specimens examined across different provider groups. The effects of these different behaviors on what Berry (1999) identified as the common core values of service organizations are examined, as those values are required to build a lasting service relationship. Also examined are categories of healthcare practice based on the National Quality Strategy priorities. The most obvious is the retrospective nature of the method used. How accurate are patient or consumer memories? Are they capable of making valid judgments of healthcare experiences (Berry and Bendapudi, 2003)? While an obvious limitation, such recollections are clearly important as they may be paramount in following the healthcare practitioners' instructions, loyalty for repeat business, making recommendations to others and the like. Further, studies have shown retrospective reports to be accurate and useful (Miller et al., 1997). With this information, healthcare educators should be in a better position to improve the training offered in their programs and practitioners to better serve their customers. The findings would indicate that the human values of excellence, innovation, joy, respect and integrity play a significant role in building a strong service relationship between consumer and healthcare provider. Berry (1999) has argued that the overriding importance in building a lasting service business is human values. This exploratory study has shown how critical incident analysis can be used to determine both effective and ineffective practices of different medical providers. It also provides guidelines as

    The Cognitive Behavioral Analysis System of Psychotherapy (CBASP) is a relatively new approach in the treatment of chronic depression (CD). Adapted as group psychotherapy for inpatients, CBASP is attracting increasing attention. In this naturalistic multicenter trial, we investigated its feasibility after 10 sessions of CBASP group therapy over a treatment time of at least 5 to a maximum of 10 weeks. Treatment outcome was additionally assessed. Across four centers, 116 inpatients with CD (DSM-IV-TR) attended CBASP group psychotherapy. Feasibility was focused on acceptance, and evaluated for patients and therapists after five (t1) and ten sessions (t2) of group psychotherapy. Observer- and self-rating scales (Hamilton Depression Rating Scale-24 items, HDRS 24 ; Beck Depression Inventory-II, BDI-II; World Health Organization Quality of Life assessment, WHOQOL-BREF) were applied before group psychotherapy (t0) and at t2. Dropouts were low (10.3%). Patients' evaluation improved significantly from t1 to t2 with a medium effect size (d = 0.60). Most of the patients stated that the group had enriched their treatment (75.3%), that the size (74.3%) and duration (72.5%) were 'optimal' and 37.3% wished for a higher frequency. Patients gave CBASP group psychotherapy an overall grade of 2 ('good'). Therapists' evaluation was positive throughout, except for size of the group. Outcome scores of HDRS 24 , BDI-II, and WHOQOL-BREF were significantly reduced from t0 to t2 with medium to large effect sizes (d = 1.48; d = 1.11; d = 0.67). In this naturalistic open-label trial, CBASP, when applied as inpatient group psychotherapy, was well accepted by patients and therapists. The results point towards a clinically meaningful effect of inpatient treatment with CBASP group psychotherapy on depression and quality of life. Other potential factors that could have promoted symptom change were discussed. A future controlled study could investigate the safety and efficacy of CBASP

    1998-08-01

    The separation behavior of Tc in the whole of 4-Group Partitioning Process was examined by a flask-scale experiment using simulated high-level liquid waste containing a macro amount of Tc, in order to confirm the reproducibility of the results obtained in previous studies on the Tc behavior at each step of the process. The 4-Group Partitioning Process consists of pre-treatment step, extraction step with diisodecylphosphoric acid (DIDPA), adsorption step with active carbon or precipitation step by denitration for the separation of Tc and platinum group metals (PGM), and adsorption step with inorganic ion exchangers. The present study deals with the behavior of Tc and other elements at all the above steps and additional step for Tc dissolution from the precipitate formed by the denitration. At the pre-treatment step, the ratio of Tc precipitated was very low (about 0.2%) at both operations of heating-denitration and colloid removal. Tc was not extracted with DIDPA and was contained quantitatively in the raffinate from the extraction step. Batch adsorption with active carbon directly from the raffinate showed that distribution coefficient of Tc was more than 100ml/g, which is high enough for the separation. It also revealed much effect of coexisting Mo on the Tc adsorption. At the precipitation step by denitration, 98.2% of Tc were precipitated. At the Tc dissolution from the precipitate with H 2 O 2 , 84.2% of Tc were selectively dissolved in a single operation. Tc was not adsorbed with inorganic ion exchangers. From these results, composition of Tc product from the partitioning process was estimated. The weight ratio of Tc in the Tc product can be increased to about 50% at least. Main contaminating elements are Cr, Ni, Sr, Ba, Mo and Pd. Process optimization to decrease their contamination should be performed in a next study. (J.P.N.)

    Objectives To characterize the usage patterns of new types of tobacco products (NTTPs) to develop effective strategies for the regulation of NTTPs in Korea. Methods We conducted focus group interviews to identify the NTTP usage patterns of research subjects. The NTTPs were limited to electronic cigarettes (e-cigarettes), waterpipe tobacco, and rolling tobacco. We categorized 30 research subjects into 4 groups. The e-cigarette group was divided into adult and adolescent groups. Each group contained 7-8 subjects. An interview lasting approximately 2 hours was conducted with each group. Results Ninety percent of NTTP users used an NTTP in combination with conventional cigarettes. Subjects mostly bought NTTPs online, unlike how they bought cigarettes. Additionally, a great deal of information, such as how to use NTTPs and descriptions of NTTP products, was exchanged through online or offline societies. The primary reason why the subjects used NTTPs was that NTTPs offer a greater range of flavors and aromas than cigarettes. Moreover, NTTPs were felt to be less repulsive than cigarettes. NTTPs were not used as a cigarette substitute; rather, they were mostly used in places and situations where traditional cigarette smoking was not allowed. Conclusions Based on the results of this study, the government should conduct studies on the effects of the combined use of NTTPs and cigarettes on the human body, obtain and provide accurate data regarding NTTP use, and develop and implement polices to ban NTTP advertising, which may arouse adolescents’ curiosity, and the addition of flavoring substances to tobacco products.

    Previous studies have shown that the dietary habits of cancer patients and survivors have significant implications for their recovery and quality of life. The current study examined the effectiveness of an innovative culinary group intervention on cancer patients' quality of life through changes in their eating behaviors, as manifested by an increase in their tendency towards intuitive eating and healthy food choices. In total, 190 cancer patients participated in this study, and were allocated to an intervention or a wait-list control group. A battery of self-report questionnaires assessing food choices, intuitive eating, health-related quality of life, and subjective well-being was administered at two time points: Before the intervention (T1) and at the end of the three month intervention (T2). Analyses revealed an increase in health-related quality of life and well-being among the intervention group. Intuitive eating and healthy food choices also increased among the intervention but not wait-list control group. Finally, results indicated that participation in the culinary group intervention and improvements in health-related quality of life and well-being were mediated by changes in eating behaviors. Our findings demonstrate that nutrition and eating behaviors have a significant effect on cancer patients' physical and emotional adjustment. A culinary group intervention seems to target patients' physical and emotional needs and promote their adjustment. Copyright © 2016 Elsevier Ltd. All rights reserved.

  8. Dysfunctional beliefs in group and individual cognitive behavioral therapy for obsessive compulsive disorder.

    Jónsson, Hjalti; Hougaard, Esben; Bennedsen, Birgit E

    2011-05-01

    The primary aim of the study was to investigate dysfunctional beliefs in the form of inflated responsibility (IR) and thought action fusion (TAF) as predictive and mediating variables in individual (n=33) and group (n=37) cognitive behavioral therapy (CBT) for obsessive compulsive disorder (OCD). IR and TAF declined significantly during CBT, and the decline was positively associated with change in OCD symptoms. However, when controlling for change in depressive symptoms, only change in IR remained significantly associated with OCD symptom change. The moral subtype of TAF predicted poorer treatment outcome, but only in group CBT. Both treatments produced a similar amount of change in the dysfunctional beliefs. The results provide some, preliminary evidence that IR, but not TAF, may be specifically involved in the change mechanisms of both individual and group CBT for OCD, although the design of the study with pre- and post-therapy measurements only does not allow for a causal mediator analysis.

    Full Text Available Background. Effective psychological treatment, including cognitive behavioral therapy and motivational interviewing (MI, is available for people with problematic gambling behaviors. To advance the development of treatment for gambling disorder, it is critical to further investigate how comorbidity impacts different types of treatments. The purpose of this study was to investigate whether screening for risky alcohol habits can provide guidance on whether people with gambling disorder should be recommended cognitive behavioral group therapy (CBGT or MI. Methods. The present study is a secondary analysis of a previous randomized controlled trial that compared the effects of CBGT, MI and a waitlist control group in the treatment of disordered gambling. Assessment and treatment was conducted at an outpatient dependency clinic in Stockholm, Sweden, where 53 trial participants with gambling disorder began treatment. A modified version of the National Opinion Research Centre DSM-IV Screen for gambling problems was used to assess gambling disorder. The Alcohol Use Disorders Identification Test (AUDIT was used to screen for risky alcohol habits. Results. The interaction between treatment and alcohol habits was significant and suggests that patients with gambling disorder and risky alcohol habits were better helped by MI, while those without risky alcohol habits were better helped by CBGT. Conclusions. The results support a screening procedure including the AUDIT prior to starting treatment for gambling disorder because the result of the screening can provide guidance in the choice of treatment. Patients with gambling disorder and risky alcohol habits are likely to be best helped if they are referred to MI, while those without risky alcohol habits are likely to be best helped if they are referred to CBGT.

    2017-03-01

    Timeouts are sometimes used in applied settings to reduce target responses, and in some circumstances delays are unavoidably imposed between the onset of a timeout and the offset of the response that produces it. The present study examined the effects of signaled and unsignaled timeouts in rats exposed to concurrent fixed-ratio 1 fixed-ratio 1 schedules of food delivery, where each response on one lever, the location of which changed across conditions, produced both food and a delayed 10-s timeout. Delays of 0 to 38 s were examined. Delayed timeouts often, but not always, substantially reduced the number of responses emitted on the lever that produced timeouts relative to the number emitted on the lever that did not produce timeouts. In general, greater sensitivity was observed to delayed timeouts when they were signaled. These results demonstrate that delayed timeouts, like other delayed consequences, can affect behavior, albeit less strongly than immediate consequences. © 2017 Society for the Experimental Analysis of Behavior.

    Secchi, Davide; Bui, Hong T M

    2018-01-01

    This study uses a quasi-experimental design to investigate what happens to individual socially responsible attitudes when they are exposed to group dynamics. Findings show that group engagement increases individual attitudes toward social responsibility. We also found that individuals with low attitudes toward social responsibility are more likely to change their opinions when group members show more positive attitudes toward social responsibility. Conversely, individuals with high attitudes do not change much, independent of group characteristics. To better analyze the effect of group dynamics, the study proposes to split social responsibility into relative and absolute components. Findings show that relative social responsibility is correlated with but different from absolute social responsibility although the latter is more susceptible than the former to group dynamics.

  17. Prenatal stressors in rodents: Effects on behavior

    Directory of Open Access Journals (Sweden)

    Marta Weinstock

    2017-02-01

    Full Text Available The current review focuses on studies in rodents published since 2008 and explores possible reasons for any differences they report in the effects of gestational stress on various types of behavior in the offspring. An abundance of experimental data shows that different maternal stressors in rodents can replicate some of the abnormalities in offspring behavior observed in humans. These include, anxiety, in juvenile and adult rats and mice, assessed in the elevated plus maze and open field tests and depression, detected in the forced swim and sucrose-preference tests. Deficits were reported in social interaction that is suggestive of pathology associated with schizophrenia, and in spatial learning and memory in adult rats in the Morris water maze test, but in most studies only males were tested. There were too few studies on the novel object recognition test at different inter-trial intervals to enable a conclusion about the effect of prenatal stress and whether any deficits are more prevalent in males. Among hippocampal glutamate receptors, NR2B was the only subtype consistently reduced in association with learning deficits. However, like in humans with schizophrenia and depression, prenatal stress lowered hippocampal levels of BDNF, which were closely correlated with decreases in hippocampal long-term potentiation. In mice, down-regulation of BDNF appeared to occur through the action of gene-methylating enzymes that are already increased above controls in prenatally-stressed neonates. In conclusion, the data obtained so far from experiments in rodents lend support to a physiological basis for the neurodevelopmental hypothesis of schizophrenia and depression.

    Critchley, Christine R; Hardie, Elizabeth A; Moore, Susan M

    2012-04-01

    To examine the psychological process of lifestyle change among adults at risk for type 2 diabetes. A randomized control trial in which 307 volunteers (intervention, n = 208; wait control, n = 99) diagnosed with prediabetes completed a six-session group-based intervention to promote healthier living. Participants' motivation to change, diet and exercise self-efficacy, mood, knowledge about diabetes, activity levels, healthy eating, waist circumference, and weight were assessed before and after the program. Participation in the program was associated with significant increases in healthy eating and physical activity, reductions in waist and weight, and improvements in motivation, positive mood, self-efficacy, and knowledge. Examination of the pathways to lifestyle change showed that the educational aspect of the program increased activity levels because it increased diabetes knowledge and improved mood. Eating behavior was not mediated by any of the psychological variables. Improvements in diet and physical activity were, in turn, directly associated with changes in weight and waist circumference. Although the program significantly improved motivation, self-efficacy, and mood, its impact on knowledge uniquely explained the increase in physical activity. Group-based programs that are tailored to lifestyle behaviors may provide a cost-effective method of diabetes prevention, but more research is needed to explain why they improve healthy eating.

    In primates, grooming is considered among the most common behaviors for maintaining social bonds; however, to date, few studies have examined grooming behavior in gibbon species in detail. We used both a 5-min interval scan method and social network analysis to study grooming in two groups of polygynous western black-crested gibbon (Nomascus concolor) in Wuliang Mountain, Central Yunnan, China. Individuals in both groups spent little time in social grooming (1.45% and 1.97% of active time). We compared the two groups' grooming networks and found that the group that maintained a more stable social unit had a more complex grooming network while the group with new immigrants had a grooming network characterized by fewer grooming pairs. Females in both groups played important roles in the grooming network. A newly immigrant female spent the most time grooming others and chose the resident adult female as her main adult grooming partner. Other females from both groups chose the adult male as their primary grooming partner (except their offspring). A sub-adult male who had resided in his natal group for 2 years after maturing into an adult also groomed more and was at the center of the network. This male finally replaced the breeding male in his group 3 years after our data collection period ended. We hypothesize that the immigrant female and the resident young adult male engaged in more extensive grooming interactions as a behavioral strategy to gain tolerance from long-term residents. Our results suggest that female gibbons in polygynous groups actively cooperate in maintaining social relationships rather than co-exist through tolerance or avoidance. Our observations indicate that grooming networks in crested gibbons reflect individual dynamics and partly support the social cohesion hypothesis for primate grooming. In this regard, we suggest that changes in gibbon grooming networks can be used to predict social change. © 2013 Wiley Periodicals, Inc.

    The current study tested whether people with and without eating disorders (EDs) varied in their implicit attitudes toward ED-relevant stimuli. Additionally, the study tested whether implicit evaluations of ED-relevant stimuli predicted ED symptoms and behaviors over a 4-week interval. Participants were people without EDs (N = 85) and people seeking treatment for EDs (N = 92). All participants completed self-report questionnaires and a version of the affect misattribution procedure (AMP) at baseline. The AMP indexed implicit evaluations of average body stimuli, eating stimuli, and ED-symptom stimuli. Participants with EDs completed weekly follow-up measures of ED symptoms and behaviors for 4 weeks. Contrary to predictions, the anorexia nervosa (AN) group did not differ from the no ED group on implicit attitudes toward ED-symptom stimuli, and the bulimia nervosa (BN) group had less positive implicit attitudes toward ED-symptom stimuli relative to the no ED group. In line with predictions, people with AN and BN had more negative implicit attitudes toward average body and eating stimuli relative to the no ED group. In addition, among the ED group more negative implicit attitudes toward eating stimuli predicted ED symptoms and behaviors 4 weeks later, over and above baseline ED symptoms and behaviors. Taken together, implicit evaluations of eating stimuli differentiated people with AN and BN from people without EDs and longitudinally predicted ED symptoms and behaviors. Interventions that increase implicit liking of eating-related stimuli may reduce ED behaviors. © 2018 Wiley Periodicals, Inc.

    Research indicates that music therapy can improve social behaviors and joint attention in children with Autism Spectrum Disorder (ASD); however, more research on the use of music therapy interventions for social skills is needed to determine the impact of group music therapy. To examine the effects of a music therapy group intervention on eye gaze, joint attention, and communication in children with ASD. Seventeen children, ages 6 to 9, with a diagnosis of ASD were randomly assigned to the music therapy group (MTG) or the no-music social skills group (SSG). Children participated in ten 50-minute group sessions over a period of 5 weeks. All group sessions were designed to target social skills. The Social Responsiveness Scale (SRS), the Autism Treatment Evaluation Checklist (ATEC), and video analysis of sessions were used to evaluate changes in social behavior. There were significant between-group differences for joint attention with peers and eye gaze towards persons, with participants in the MTG demonstrating greater gains. There were no significant between-group differences for initiation of communication, response to communication, or social withdraw/behaviors. There was a significant interaction between time and group for SRS scores, with improvements for the MTG but not the SSG. Scores on the ATEC did not differ over time between the MTG and SSG. The results of this study support further research on the use of music therapy group interventions for social skills in children with ASD. Statistical results demonstrate initial support for the use of music therapy social groups to develop joint attention. © the American Music Therapy Association 2014. All rights reserved.

  5. Supramolecular effects in dendritic systems containing photoactive groups

    2000-03-01

    Full Text Available In this article are described dendritic structures containing photoactive groups at the surface or in the core. The observed supramolecular effects can be attributed to the nature of the photoactive group and their location in the dendritic architecture. The peripheric azobenzene groups in these dendrimeric compounds can be regarded as single residues that retain the spectroscopic and photochemical properties of free azobenzene moiety. The E and Z forms of higher generation dendrimer, functionalized with azobenzene groups, show different host ability towards eosin dye, suggesting the possibility of using such dendrimer in photocontrolled host-guest systems. The photophysical properties of many dendritic-bipyridine ruthenium complexes have been investigated. Particularly in aerated medium more intense emission and a longer excited-state lifetime are observed as compared to the parent unsubstituted bipyridine ruthenium complexes. These differences can be attributed to a shielding effect towards dioxygen quenching originated by the dendritic branches.

    Full Text Available Post-streptococcal A (GAS sequelae including movement and neuropsychiatric disorders have been associated with improvement in response to antibiotic therapy. Besides eradication of infection, the underlying basis of attenuation of neuropsychiatric symptoms following antibiotic treatment is not known. The aim of the present study was to test the efficacy of antibiotic treatment in a rat model of GAS-related neuropsychiatric disorders. In the model, rats were not infected but were exposed to GAS-antigen or to adjuvants only (Control rats and treated continuously with the antibiotic ampicillin in their drinking water from the first day of GAS-antigen exposure. Two additional groups of rats (GAS and Control did not receive ampicillin in their drinking water. Behavior of the four groups was assessed in the forced swim, marble burying and food manipulation assays. We assessed levels of D1 and D2 dopamine receptors and tyrosine hydroxylase in the prefrontal cortex and striatum, and IgG deposition in the prefrontal cortex, striatum and thalamus. Ampicillin treatment prevented emergence of the motor and some of the behavioral alterations induced by GAS-antigen exposure, reduced IgG deposition in the thalamus of GAS-exposed rats, and tended to attenuate the increase in the level of TH and D1 and D2 receptors in their striatum, without concomitantly reducing the level of sera anti-GAS antibodies. Our results reinforce the link between exposure to GAS antigen, dysfunction of central dopaminergic pathways and motor and behavioral alterations. Our data further show that some of these deleterious effects can be attenuated by antibiotic treatment, and supports the latter's possible efficacy as a prophylactic treatment in GAS-related neuropsychiatric disorders.

    Full Text Available Objectives To characterize the usage patterns of new types of tobacco products (NTTPs to develop effective strategies for the regulation of NTTPs in Korea. Methods We conducted focus group interviews to identify the NTTP usage patterns of research subjects. The NTTPs were limited to electronic cigarettes (e-cigarettes, waterpipe tobacco, and rolling tobacco. We categorized 30 research subjects into 4 groups. The e-cigarette group was divided into adult and adolescent groups. Each group contained 7-8 subjects. An interview lasting approximately 2 hours was conducted with each group. Results Ninety percent of NTTP users used an NTTP in combination with conventional cigarettes. Subjects mostly bought NTTPs online, unlike how they bought cigarettes. Additionally, a great deal of information, such as how to use NTTPs and descriptions of NTTP products, was exchanged through online or offline societies. The primary reason why the subjects used NTTPs was that NTTPs offer a greater range of flavors and aromas than cigarettes. Moreover, NTTPs were felt to be less repulsive than cigarettes. NTTPs were not used as a cigarette substitute; rather, they were mostly used in places and situations where traditional cigarette smoking was not allowed. Conclusions Based on the results of this study, the government should conduct studies on the effects of the combined use of NTTPs and cigarettes on the human body, obtain and provide accurate data regarding NTTP use, and develop and implement polices to ban NTTP advertising, which may arouse adolescents’ curiosity, and the addition of flavoring substances to tobacco products.

    We present behavioral characteristics of teens and adults in Instagram and prediction of them from their behaviors. Based on two independently created datasets from user profiles and tags, we identify teens and adults, and carry out comparative analyses on their online behaviors. Our study reveals: (1) significant behavioral differences between two age groups; (2) the empirical evidence of classifying teens and adults with up to 82% accuracy, using traditional predictive models, while two baseline methods achieve 68% at best; and (3) the robustness of our models by achieving 76%—81% when tested against an independent dataset obtained without using user profiles or tags.

    It is obvious that light entering the eye permits the sensory capacity of vision. The human species is highly dependent on visual perception of the environment and consequently, the scientific study of vision and visual mechanisms is a centuries old endeavor. Relatively new discoveries are now leading to an expanded understanding of the role of light entering the eye - in addition to supporting vision, light has various nonvisual biological effects. Over the past thirty years, animal studies have shown that environmental light is the primary stimulus for regulating circadian rhythms, seasonal cycles, and neuroendocrine responses. As with all photobiological phenomena, the wavelength, intensity, timing and duration of a light stimulus is important in determining its regulatory influence on the circadian and neuroendocrine systems. Initially, the effects of light on rhythms and hormones were observed only in sub-human species. Research over the past decade, however, has confirmed that light entering the eyes of humans is a potent stimulus for controlling physiological rhythms. The aim of this paper is to examine three specific nonvisual responses in humans which are mediated by light entering the eye: light-induced melatonin suppression, light therapy for winter depression, and enhancement of nighttime performance. This will serve as a brief introduction to the growing database which demonstrates how light stimuli can influence physiology, mood and behavior in humans. Such information greatly expands our understanding of the human eye and will ultimately change our use of light in the human environment.

    Full Text Available Group work permits students to develop a range of critical thinking, analytical and communication skills; effective team work; appreciation and respect for other views, techniques and problem-solving methods, all of which promote active learning and enhance student learning. This paper presents an evaluation of employing the didactic and pedagogical customs of group work in mathematics with the aim of improving student performance as well as exploring students’ perceptions of working in groups. The evaluation of group work was carried out during tutorial time with first year civil engineering students undertaking a mathematics module in their second semester. The aim was to investigate whether group work learning can help students gain a deeper understanding of the module content, develop improved critical and analytical thinking skills and see if this method of pedagogy can produce higher performance levels. The group work sessions were conducted over four weeks whilst studying the topic of integration. Evaluation surveys were collected at the end of the intervention along with an investigation into the examination results from the end of semester examinations. In order to derive plausible and reasonable conclusions, these examination results were compared with an analogous cohort of first year mathematics students, also studying integration in their engineering-based degree. The investigation into the effectiveness of group work showed interesting and encouraging positive outcomes, supported by a combination of qualitative and quantitative analysis.

    Objective: To investigate the effect of behavior training on the learning and memory of young rats with fetal growth restriction (FGR). Methods: The model of FGR was established by passive smoking method to pregnant rats.The new-born rats were divided into FGR group and normal group, and then randomly subdivided into trained and untrained group respectively. Morris water maze behavior training was performed on postnatal months 2 and 4, then learning and memory abilities of young rats were measured by dark-avoidance testing and step-down testing. Results: In the dark-avoidance and step-down testing, the young rats' performance of FGR group was worse than that of control group, and the trained group was better than the untrained group significantly. Conclusion: FGR young rats have descended learning and memory abilities. Behavior training could improve the young rats' learning and memory abilities, especially for the FGR young rats.

    2018-07-01

    Recent theoretical accounts of verbal and visuo-spatial short-term memory (STM) have proposed the existence of domain-general mechanisms for the maintenance of serial order information. These accounts are based on the observation of similar behavioural effects across several modalities, such as temporal grouping effects. Across two experiments, the present study aimed at extending these findings, by exploring a STM modality that has received little interest so far, STM for musical information. Given its inherent rhythmic, temporal and serial organisation, the musical domain is of interest for investigating serial order STM processes such as temporal grouping. In Experiment 1, the data did not allow to determine the presence or the absence of temporal grouping effects. In Experiment 2, we observed that temporal grouping of tone sequences during encoding improves short-term recognition for serially presented probe tones. Furthermore, the serial position curves included micro-primacy and micro-recency effects, which are the hallmark characteristic of temporal grouping. Our results suggest that the encoding of serial order information in musical STM may be supported by temporal positional coding mechanisms similar to those reported in the verbal domain.

  16. The relationship between interpersonal problems, negative cognitions, and outcomes from cognitive behavioral group therapy for depression.

    Interpersonal functioning is a key determinant of psychological well-being, and interpersonal problems (IPs) are common among individuals with psychiatric disorders. However, IPs are rarely formally assessed in clinical practice or within cognitive behavior therapy research trials as predictors of treatment attrition and outcome. The main aim of this study was to investigate the relationship between IPs, depressogenic cognitions, and treatment outcome in a large clinical sample receiving cognitive behavioral group therapy (CBGT) for depression in a community clinic. Patients (N=144) referred for treatment completed measures of IPs, negative cognitions, depression symptoms, and quality of life (QoL) before and at the completion of a 12-week manualized CBGT protocol. Two IPs at pre-treatment, 'finding it hard to be supportive of others' and 'not being open about problems,' were associated with higher attrition. Pre-treatment IPs also predicted higher post-treatment depression symptoms (but not QoL) after controlling for pre-treatment symptoms, negative cognitions, demographics, and comorbidity. In particular, 'difficulty being assertive' and a 'tendency to subjugate one's needs' were associated with higher post-treatment depression symptoms. Changes in IPs did not predict post-treatment depression symptoms or QoL when controlling for changes in negative cognitions, pre-treatment symptoms, demographics, and comorbidity. In contrast, changes in negative cognitions predicted both post-treatment depression and QoL, even after controlling for changes in IPs and the other covariates. Correlational design, potential attrition bias, generalizability to other disorders and treatments needs to be evaluated. Pre-treatment IPs may increase risk of dropout and predict poorer outcomes, but changes in negative cognitions during treatment were most strongly associated with improvement in symptoms and QoL during CBGT.

    Encouraging cooperation among selfish individuals is crucial in many real-world systems, where individuals' collective behaviors can be analyzed using evolutionary public goods game. Along this line, extensive studies have shown that reputation is an effective mechanism to investigate the evolution of cooperation. In most existing studies, participating individuals in a public goods game are assumed to contribute unconditionally into the public pool, or they can choose partners based on a common reputation standard (e.g., preferences or characters). However, to assign one reputation standard for all individuals is impractical in many real-world deployment. In this paper, we introduce a reputation tolerance mechanism that allows an individual to select its potential partners and decide whether or not to contribute an investment to the public pool based on its tolerance to other individuals' reputation. Specifically, an individual takes part in a public goods game only if the number of participants with higher reputation exceeds the value of its tolerance. Moreover, in this paper, an individual's reputation can increase or decrease in a bounded interval based on its historical behaviors. We explore the principle that how the reputation tolerance and conditional investment mechanisms can affect the evolution of cooperation in spatial lattice networks. Our simulation results demonstrate that a larger tolerance value can achieve an environment that promote the cooperation of participants.

    Full Text Available Background: Efficacy studies on treatment in adolescent victims of single rape are lacking, even though sexual victimization is most likely to occur during adolescence and despite the fact that adolescents are at risk to develop subsequent posttraumatic stress disorder. Aim: The aim of this prospective observational study was to evaluate the short- and long-term outcomes of a nine-session cognitive behavior group therapy (STEPS, including a parallel six-session parents’ group on rape-related symptomatology in female adolescents (13–18 years. STEPS includes psychoeducation, exposure in sensu as well as in vivo, cognitive restructuring, and relapse prevention. Methods: Fifty-five female adolescents with mental health problems due to single rape, but without prior sexual trauma, received STEPS while their parents participated in a support group. Subjects were assessed on posttraumatic stress (PTS and comorbid symptoms using self-report questionnaires prior to and directly after treatment, and at 6 and 12 months follow-up. Results: Repeated measures analysis showed a significant and large decrease in symptoms of PTS, anxiety, depression, anger, dissociation, sexual concerns, and behavior problems directly after treatment, which maintained at 12 months follow-up. Time since trauma did not influence the results. Dropout during STEPS was 1.8%. Conclusions: The results potentially suggest that the positive treatment outcomes at short- and long-term may be caused by STEPS. The encouraging findings need confirmation in future controlled studies on the effectiveness of STEPS because it may be possible that the treatment works especially well for more chronic symptoms, while the less chronic part of the sample showed considerable improvement on its own.

    College students' use of protective behavioral strategies (PBS; e.g., determining not to exceed a set number of drinks, avoiding drinking games) is related to lower levels of alcohol consumption and problems. The present study evaluated the efficacy of a novel brief, single-session group PBS skills training intervention aimed at increasing college students' use of PBS and reducing risky drinking and consequences. Participants (N = 226) were heavy-drinking incoming first-year college women randomized to either a PBS skills training intervention or study skills control condition. Participants attended a 45-min group session and completed online surveys pre- and postintervention (1 month and 6 months). We conducted a series of 2 × 2 × 3 repeated-measures ANCOVAs with condition and baseline mental health (anxiety/depression) as the between-subjects factors and time as the within-subjects factor. Intervention participants, relative to controls, reported significantly greater increases in PBS use and reductions in both heavy episodic drinking and alcohol consequences. The intervention was particularly effective in increasing PBS use at 1 month among participants with high anxiety. Further, tests of moderated mediation showed a significant conditional indirect effect of condition on 1-month consequences through PBS use among participants with high levels of anxiety. Findings provide preliminary support for a brief PBS-specific group intervention to reduce alcohol risk among college women, particularly anxious women. Future research is needed to strengthen the long-term effectiveness of the present approach and further explore the moderating effects of mental health.

  5. Creating Effective Collaborative Learning Groups in an Online Environment

    2009-06-01

    Full Text Available Collaborative learning in an online classroom can take the form of discussion among the whole class or within smaller groups. This paper addresses the latter, examining first whether assessment makes a difference to the level of learner participation and then considering other factors involved in creating effective collaborative learning groups. Data collected over a three year period (15 cohorts from the Foundations course in the Master of Distance Education (MDE program offered jointly by University of Maryland University College (UMUC and the University of Oldenburg does not support the authors’ original hypothesis that assessment makes a significant difference to learner participation levels in small group learning projects and leads them to question how much emphasis should be placed on grading work completed in study groups to the exclusion of other strategies. Drawing on observations of two MDE courses, including the Foundations course, their extensive online teaching experience, and a review of the literature, the authors identify factors other than grading that contribute positively to the effectiveness of small collaborative learning groups in the online environment. In particular, the paper focuses on specific instructional strategies that facilitate learner participation in small group projects, which result in an enhanced sense of community, increased skill acquisition, and better learning outcomes.

The ordinary effective action Γ{sub 0} can be obtained by integrating the flow equation from an ultraviolet scale k = Λ down to k = 0. We give several examples of such calculations at one-loop, both in renormalizable and in effective field theories. We reproduce the four-point scattering amplitude in the case of a real scalar field theory with quartic potential and in the case of the pion chiral Lagrangian. In the case of gauge theories, we reproduce the vacuum polarization of QED and of Yang-Mills theory. We also compute the two-point functions for scalars and gravitons in the effective field theory of scalar fields minimally coupled to gravity. (orig.)

    This study examined whether the authoritative parenting model (APM) is more effective than conventional approaches for changing adolescent oral hygiene behavior. A total of 247 adolescents were recruited using a cluster random-sampling method. Subject groups were randomly allocated into an intervention group (APM-based interventions), a Control Group 1 (conventional dental education and behavior modification) or a Control Group 2 (conventional behavior modification). The results were assessed after 3 and 12 months. Oral hygiene level was assessed as percent dental plaque and the ratio of plaque percent change (RPC). At the 3-month follow-up, there were significant differences among the groups; the APM group had the largest decrease in plaque levels (24.5%), Control Group 1 showed a decrease in plaque levels of 15.4% and Control Group 2 showed an increase in plaque levels of 2.8%. At the 12-month follow-up, an improvement was observed in all groups, but there were no statistically significant differences among the groups. In the short term, the intervention based on the APM was more effective in changing adolescent oral hygiene behavior compared with the conventional approaches. The reasons for long-term positive change after discontinued interventions in control groups need to be explored in future studies.

    Highlights: •Cooperation macrocosmically refers to the overall cooperation rate, while reputation microcosmically records individual choices. •Therefore, reputation should be preferred in order to investigate how individual choices evolve. •Both the mean and standard deviation of reputation follow clear patterns, and some factors have quadratic effects on them. -- Abstract: Cooperation is vital for our society, but the temptation of cheating on cooperative partners undermines cooperation. The mechanism of reputation is raised to countervail this temptation and therefore promote cooperation. Reputation microcosmically records individual choices, while cooperation macrocosmically refers to the group or averaged cooperation level. Reputation should be preferred in order to investigate how individual choices evolve. In this work, we study the distribution of reputation to figure out how individuals make choices within cooperation and defection. We decompose reputation into its mean and standard deviation and inspect effects of their factors respectively. To achieve this goal, we construct a model where agents of three groups or classes play the prisoners’ dilemma game with neighbors on a square lattice. It indicates in outcomes that the distribution of reputation is distinct from that of cooperation and both the mean and standard deviation of reputation follow clear patterns. Some factors have negative quadratic effects on reputation's mean or standard deviation, and some have merely linear effects

    To provide a cigarette price elasticity reference for adult age groups, and to estimate the smoking behaviour changes in US adults in light of unprecedented state excise tax increases on cigarettes during the 1990s. Individual-level data from the Behavioral Risk Factor Surveillance System for 1993-2000 were merged with state-level cigarette price and tax data. Data were analysed for different age groups using a weighted least squares regression framework. The outcome variables measured were whether an individual was a smoker, whether he/she had tried to quit smoking during the previous year, and how many cigarettes were smoked per day among the total population and among active smokers. This study confirmed previous results that younger individuals are more responsive to price changes than older individuals. Although older age groups are less sensitive to price changes, their smoking behaviour changes are still statistically significant. This study found that while older individuals are less responsive to price changes than younger individuals, their behavioural changes due to cigarette price increases should not be ignored.

    Incarcerated women report multiple vulnerabilities and, yet, are under-represented in research. This study used focus-group methodology to explore high-risk sexual behaviors, drug use, and victimization among female offenders in St. Louis. Inmates of the St. Louis Medium Security Institution (MSI) were invited to participate in one of five focus groups between May and September 2005 in preparation for an NIH/NINR HIV-prevention intervention study among female offenders in Drug Court. The focus group sample of 30 women was 70% African-American, with a mean age of 36 years. Results indicated that oral sex was the most common sex trade activity. Consistent with the literature, condom usage was described as irregular. In terms of drug use, participants reported that crack was most commonly used, with binges often lasting for several days. Regarding victimization, women frequently reported sexual abuse in childhood, and some described abusive relationships as adults. Participants also reported being beaten and raped by customers, which led to their concealing knives in purses and razors under the tongue. Consequently, perpetrated violence, including murder, was reported as protection against further violence. These findings confirm the vulnerability of this population of women who are at high risk for HIV. Effective HIV-prevention interventions are needed to assist these incarcerated women in making lifestyle changes during incarceration and sustaining them after release.

    Caffeinated products are widely available to adolescents, and consumption of caffeine products-energy drinks and coffee in particular-is on the rise in this age group (Branum, Rossen, & Schoendorf, 2014). Yet, little is known about the psychosocial context of caffeine use. Previous studies on adolescent caffeine use have focused on caffeine's acute physiological effects, rather than the psychosocial contexts and beliefs regarding different types of caffeinated beverages (e.g., coffee, energy drinks, soda). The current research examines the contexts and beliefs associated with adolescents' use of caffeinated beverages (e.g., coffee, energy drinks, soda) using a focus group approach. Eleven focus group interviews (49 total participants) addressed adolescents' motivations for and patterns of caffeine use; they were transcribed and axial coding was used to identify common themes. Coffee and energy drinks were perceived to be the most popular caffeinated beverages. Reasons for consuming caffeine included the effect of caffeine as a stimulant, the pleasant feelings experienced when drinking it, and the fact that caffeine was available. As for contexts, coffee was consumed in more diverse social contexts than other caffeinated beverages. Friends and sports were the most popular contexts for energy drink use. The present findings inform adolescent health promotion efforts and provide researchers and practitioners alike detailed information in adolescents' own words about how and why they use caffeine. Adolescents' beliefs about caffeinated products are not uniform; the reasons adolescents articulate regarding their use of coffee, soda, and energy drinks are different across contexts and beverage type.

    To expand our understanding of fission-fusion behavior and determine its variability among primates, studies of both individual-based and group-based fission-fusion are necessary. We conducted a parallel tracking study of male and female Japanese macaques (Macaca fuscata yakui) during the non-mating season to clarify the general features of separate ranging by males of this species, an example of fission-fusion behavior, and to reveal its associated costs and benefits. Males frequently engaged in short-term separate ranging, leaving the company of females and ranging on their own for periods averaging 68 min in duration. However, the males did not venture outside the group's home range. When ranging separately from the group, males spent more time feeding, particularly on fruit, stayed longer in each feeding tree, and fed at a lower rate than when ranging with the group. These behavioral changes suggest that males can avoid within-group feeding competition by ranging alone. However, this behavior was also associated with higher traveling costs, and these separated males were more vulnerable to intergroup competition and had fewer opportunities for social interaction. The frequency of separate ranging was lower when highly clumped food plant species were the main food source. Lower-ranked males, who received more aggression when ranging with the group, exhibited a higher frequency of separate ranging. This behavioral flexibility with respect to group cohesion may allow males to reduce the costs of group living without completely losing the benefits. Specifically, by ranging alone, males may acquire sufficient feeding time without being disturbed by other group members. Conversely, when ranging with the group, males can access grooming partners and advantages in intergroup competition. © 2013 Wiley Periodicals, Inc.

    Procrastination is a common problem among university students, with at least half of the population reporting great difficulties initiating or completing tasks and assignments. Procrastination can have a negative impact on course grades and the ability to achieve a university degree, but can also lead to psychological distress. Cognitive behavior therapy (CBT) is believed to reduce procrastination, but few studies have investigated its effectiveness in a regular clinical setting. The current study explored its effects using a pragmatic randomized controlled trial comparing treatment delivered during 8 weeks as self-guided CBT via the Internet (ICBT) or as group CBT. In total, 92 university students with severe procrastination were included in the study (registered as a clinical trial on Clinicaltrials.gov: NCT02112383). Outcome measures on procrastination, depression, anxiety, and well-being were distributed at pre- and posttreatment as well as 6-month follow-up. An outcome measure of procrastination was administered weekly. Linear mixed and fixed effects models were calculated, along with improvement and deterioration rates. The results showed large within-group effect sizes on procrastination, Cohen's d of 1.29 for ICBT, 95% Confidence Interval (CI) [0.81, 1.74], and d of 1.24 for group CBT, 95% CI [0.76, 1.70], and small to moderate benefits for depression, anxiety, and well-being. In total, 33.7% were regarded as improved at posttreatment and 46.7% at follow-up. No differences between conditions were observed after the treatment period, however, participants in group CBT continued or maintained their improvement at follow-up, while participants in self-guided ICBT showed some signs of deterioration. The findings from the current study suggest that CBT might be an effective treatment for those struggling with severe procrastination, but that a group format may be better for some to sustain their benefits over time and that the clinical significance of the

    2012-06-01

    Recent research suggests that intolerance of uncertainty (IU), most commonly associated with generalized anxiety disorder, also contributes to symptoms of social phobia. This study examines the relationship between IU and social anxiety symptoms across treatment. Changes in IU, social anxiety symptoms, and depression symptoms were examined following cognitive behavior group therapy (CBGT) for social phobia (N=32). CBGT led to significant improvements in symptoms of social anxiety and depression, as well as reductions in IU. Reductions in IU were associated with reductions in social anxiety but were unrelated to improvements in depression symptoms. Reductions in IU were predictive of post-treatment social phobia symptoms after controlling for pre-treatment social phobia symptoms and changes in depression symptoms following treatment. The relationship between IU and social anxiety requires further examination within experimental and longitudinal designs, and needs to take into account additional constructs that are thought to maintain social phobia. Current findings suggest that the enhancing tolerance of uncertainty may play a role in the optimal management of social phobia. Theoretical and clinical implications are discussed.

    This paper investigates the determinants of pro-environmental consumption, focusing on the role of reference groups and routine behavior. We study the factors that explain whether or not people have installed residential solar energy equipment or have subscribed to green-electricity programs, and the factors that influence the intensity of buying organic food. In addition to demographic characteristics and environmental attitudes, we consider the following categories of determinants: economic and cognitive factors (income, estimated price premium, level of information on environmentally-friendly goods); consumption patterns of reference persons; own consumption patterns in the past. Using a unique data set from a survey conducted in the region of Hanover, Germany, we find the following: (1) Economic and cognitive factors are significant covariates of all three kinds of pro-environmental consumption. Their influence is greatest in the case of green electricity. (2) Consumption patterns of reference persons are significant covariates of all three kinds of pro-environmental consumption. Their influence is greatest in the case of organic food. (3) The intensity of buying organic food is greater the longer people have been consumers of these goods. (author)

  4. Transgenerational effects of environmental enrichment on repetitive motor behavior development.

    2016-07-01

    The favorable consequences of environmental enrichment (EE) on brain and behavior development are well documented. Much less is known, however, about transgenerational benefits of EE on non-enriched offspring. We explored whether transgenerational effects of EE might extend to the development of repetitive motor behaviors in deer mice. Repetitive motor behaviors are invariant patterns of movement that, across species, can be reduced by EE. We found that EE not only attenuated the development of repetitive behavior in dams, but also in their non-enriched offspring. Moreover, maternal behavior did not seem to mediate the transgenerational effect we found, although repetitive behavior was affected by reproductive experience. These data support a beneficial transgenerational effect of EE on repetitive behavior development and suggest a novel benefit of reproductive experience. Copyright © 2016 Elsevier B.V.

    To develop a reliable coding scheme for components of group-based behavioral support for smoking cessation, to establish the frequency of inclusion in English Stop-Smoking Service (SSS) treatment manuals of specific components, and to investigate the associations between inclusion of behavior change techniques (BCTs) and service success rates. A taxonomy of BCTs specific to group-based behavioral support was developed and reliability of use assessed. All English SSSs (n = 145) were contacted to request their group-support treatment manuals. BCTs included in the manuals were identified using this taxonomy. Associations between inclusion of specific BCTs and short-term (4-week) self-reported quit outcomes were assessed. Fourteen group-support BCTs were identified with >90% agreement between coders. One hundred and seven services responded to the request for group-support manuals of which 30 had suitable documents. On average, 7 BCTs were included in each manual. Two were positively associated with 4-week quit rates: "communicate group member identities" and a "betting game" (a financial deposit that is lost if a stop-smoking "buddy" relapses). It is possible to reliably code group-specific BCTs for smoking cessation. Fourteen such techniques are present in guideline documents of which 2 appear to be associated with higher short-term self-reported quit rates when included in treatment manuals of English SSSs.

    This research examined the impact of operant reinforcement of positive self-descriptive behavior on the self-concepts and classroom behavior of 60 fifth-grade students. Three groups of 10 male and 10 female low self-concept students wrote a series of eight essays describing their school performance. The first group (P) received written reinforcement for positive self-descriptions of their school performance. The second group (G) received an equal number of reinforcements for general statements. The third group (C) received no reinforcement for written statements. Three areas of self-concept were measured with the Primary Self-Concept Inventory: personal-self, social-self, and intellectual-self. A frequency count was also made of nine classroom behaviors thought to be influenced by self-concept. The P group displayed increases in the frequency of positive self-descriptive statement and in intellectual self-concept but no changes in personal self-concept, social self-concept, or the nine classroom behaviors. The G and C groups showed no change in self-description, self-concept, or the nine classroom behaviors.

The anxiety, depression and disappointment are more common than the others.  Hopefully thinking and cancer in two ways are related together. First the hopeful people use The problem-focused coping strategies more than the others and show less anxious and more agreement to diagnosis and treatment of cancer. So the goal of this survey is the effect of group hope therapy on reciliency of cancer patients. In this survey the Quasi-experiment and pre-test and pro test with control group is used. The society are all of the cancer patients who are coming to Kashan Imam Hassan institution and 16 of them are chose by available sampling and randomly put in two trial and control group. The trial group participated in nine group consultation sessions and the control group had no education. For toleration testing the Conroy Davidson questionnaire 2003 is used. Data are analysed by co variance analysis. The results show that the group hope therapy had a meaning full effect on toleration and the idea of personal competency, negative affection tolerance and acceptation of positive changing and spiritual control and affection s are affected the scales. Hope let people to have no stress and enable them to try to reach to their goals, the hope therapy try to enable people to have a view beyond the current situation and pain and suffering. So the toleration is not more than tolerance of the difficult situations and every things that make better the situation of cancer patients will increase the toreciliency.

    Conclusion: Anxiety levels were reduced significantly after CBGT sessions and also differences between therapy and the comparation groups were important. Therefore it was interpreted that CBGT was effective for reducing anxiety levels in children. Anxiety levels of parents were reduced after their children’s CBGT sessions; it is showed that whole family is playing an important role in anxiety treatment. Many research in the literature highlights that parents play crucial role in emerging anxiety sympoms of their children. [JCBPR 2015; 4(1.000: 26-37

    A new applicable effective-field renormalization-group (ERFG) scheme for computing critical properties of Ising spins systems is proposed and used to study the phase diagrams of a quenched bond-mixed spin Ising model on square and Kagomé lattices. The present EFRG approach yields results which improves substantially on those obtained from standard mean-field renormalization-group (MFRG) method. In particular, it is shown that the EFRG scheme correctly distinguishes the geometry of the lattice structure even when working with the smallest possible clusters, namely N'=1 and N=2.

    2013-06-01

    Conventional group analysis is usually performed with Student-type t-test, regression, or standard AN(C)OVA in which the variance-covariance matrix is presumed to have a simple structure. Some correction approaches are adopted when assumptions about the covariance structure is violated. However, as experiments are designed with different degrees of sophistication, these traditional methods can become cumbersome, or even be unable to handle the situation at hand. For example, most current FMRI software packages have difficulty analyzing the following scenarios at group level: (1) taking within-subject variability into account when there are effect estimates from multiple runs or sessions; (2) continuous explanatory variables (covariates) modeling in the presence of a within-subject (repeated measures) factor, multiple subject-grouping (between-subjects) factors, or the mixture of both; (3) subject-specific adjustments in covariate modeling; (4) group analysis with estimation of hemodynamic response (HDR) function by multiple basis functions; (5) various cases of missing data in longitudinal studies; and (6) group studies involving family members or twins. Here we present a linear mixed-effects modeling (LME) methodology that extends the conventional group analysis approach to analyze many complicated cases, including the six prototypes delineated above, whose analyses would be otherwise either difficult or unfeasible under traditional frameworks such as AN(C)OVA and general linear model (GLM). In addition, the strength of the LME framework lies in its flexibility to model and estimate the variance-covariance structures for both random effects and residuals. The intraclass correlation (ICC) values can be easily obtained with an LME model with crossed random effects, even at the presence of confounding fixed effects. The simulations of one prototypical scenario indicate that the LME modeling keeps a balance between the control for false positives and the sensitivity

    This study analyzes the interobserver agreement and hypothesis-based known-group validity of the Therapist's Verbal Behavior Category System (SISC-INTER). The SISC-INTER is a behavioral observation protocol comprised of a set of verbal categories representing putative behavioral functions of the in-session verbal behavior of a therapist (e.g., discriminative, reinforcing, punishing, and motivational operations). The complete therapeutic process of a clinical case of an individual with marital problems was recorded (10 sessions, 8 hours), and data were arranged in a temporal sequence using 10-min periods. Hypotheses based on the expected performance of the putative behavioral functions portrayed by the SISC-INTER codes across prevalent clinical activities (i.e., assessing, explaining, Socratic method, providing clinical guidance) were tested using autoregressive integrated moving average (ARIMA) models. Known-group validity analyses provided support to all hypotheses. The SISC-INTER may be a useful tool to describe therapist-client interaction in operant terms. The utility of reliable and valid protocols for the descriptive analysis of clinical practice in terms of verbal behavior is discussed. Copyright © 2011. Published by Elsevier Ltd.

    Previous research on transactive memory has found a positive relationship between transactive memory system development and group performance in single project laboratory and ad hoc groups. Closely related research on shared mental models and expertise recognition supports these findings. In this study, the author examined the relationship between transactive memory systems and performance in mature, continuing groups. A group's transactive memory system, measured as a combination of knowledge stock, knowledge specialization, transactive memory consensus, and transactive memory accuracy, is positively related to group goal performance, external group evaluations, and internal group evaluations. The positive relationship with group performance was found to hold for both task and external relationship transactive memory systems.

    Whether cocaine locomotor conditioning represents a cocaine positive effect; i.e., a Pavlovian cocaine conditioned response; or, a cocaine negative effect; i.e., interference with habituation to the test environment, is a subject of some controversy. Three separate experiments were conducted to compare the behavior (locomotion and grooming) of separate groups of rats given 1, 9 or 14 cocaine (10 mg/kg) treatments paired/unpaired with placement into an open-field arena. The behavior of the coc...

    Full Text Available This study was conducted to investigate the effectiveness of gestalt therapy and cognitive -behavioral therapy on assertiveness in middle school students. This study was a pre-post test experimental design. By cluster sampling between schools in Sharyar two schools were selected randomly. After conducting Gambrel and Rigy Questionnaire, 30 students were selected and assigned to three groups randomly. 8 sessions of gestalt therapy were implemented for one group and 8 sessions of cognitive- behavioral therapy were implemented for another group. The control group received no intervention. ANCOVA and Post hoc LSD Test were applied to analyze data. ANCOVA showed significant differences between groups. Post hoc LSD Test showed significant difference between the control group and the gestalt therapy and between the control group and cognitive -behavioral therapy group(P≤0/01, but there was no significant difference between the gestalt therapy and the cognitive- behavioral therapy group. Both gestalt therapy and cognitive- behavioral therapy had increased the assertiveness.
