To analyze the effect of psychological intervention on reducing performance anxiety and the consequences of the intervention on first-year pharmacy students. In this experimental study, 236 first-year undergraduate pharmacy students from a private university in Malaysia were approached between weeks 5 and 7 of their first semester to participate in the study. The completed responses for the Westside Test Anxiety Scale (WTAS), the Kessler Perceived Distress Scale (PDS), and the Academic Motivation Scale (AMS) were received from 225 students. Out of 225 students, 42 exhibited moderate to high test anxiety according to the WTAS (score ranging from 30 to 39) and were randomly placed into either an experiment group (n=21) or a waiting list control group (n=21). The prevalence of test anxiety among pharmacy students in this study was lower compared to other university students in previous studies. The present study's anxiety management of psychoeducation and systematic education for test anxiety reduced lack of motivation and psychological distress and improved grade point average (GPA). Psychological intervention helped significantly reduce scores of test anxiety, psychological distress, and lack of motivation, and it helped improve students' GPA.

The treatment of schizophrenia includes the use of psychotropic drugs, psychotherapy, and psychosocial interventions that include psychoeducation. This strategy has been defined as the delivery of information about the disorder and its treatment in a systematic and structured way. To review the literature on the efficacy of psychoeducation in schizophrenia. A search in PubMed, SciELO, EMBASE and PsycINFO was made with the terms "psychoeducation", "schizophrenia" and "psychosocial intervention". Articles in Spanish and English language were reviewed. Psychoeducation can be applied to patients, family or both, and individually or in groups. The number of sessions can vary. There have been many studies that seek to determine the efficacy of psychoeducation in the clinical course, family dynamics and stigma, with results that favor its implementation, but so far it has not been possible to determine exactly how best to apply psychoeducation, mainly because of the great variability of designs. The studies on psychoeducation have shown efficacy. However, this might be an overestimation, as there is a high risk of bias. Consequently, there is not enough evidence. At least for now, it is reasonable to complement pharmacotherapy with psycoeducation. Copyright © 2014 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España. All rights reserved.

Background Schizophrenia can be a severe and chronic illness characterised by lack of insight and poor compliance with treatment. Psychoeducational approaches have been developed to increase patients’ knowledge of, and insight into, their illness and its treatment. It is supposed that this increased knowledge and insight will enable people with schizophrenia to cope in a more effective way with their illness, thereby improving prognosis. Objectives To assess the effects of psychoeducational interventions compared with standard levels of knowledge provision. Search methods We searched the Cochrane Schizophrenia Group Trials Register (February 2010). We updated this search November 2012 and added 27 new trials to the awaiting assessment section. Selection criteria All relevant randomised controlled trials focusing on psychoeducation for schizophrenia and/or related serious mental illnesses involving individuals or groups. We excluded quasi-randomised trials. Data collection and analysis At least two review authors extracted data independently from included papers. We contacted authors of trials for additional and missing data. We calculated risk ratios (RR) and 95% confidence intervals (CI) of homogeneous dichotomous data. We used a fixed-effects model for heterogeneous dichotomous data. Where possible we also calculated the numbers needed to treat (NNT), as well as weighted means for continuous data. Main results This review includes a total of 5142 participants (mostly inpatients) from 44 trials conducted between 1988 and 2009 (median study duration ~ 12 weeks, risk of bias - moderate). We found that incidences of non-compliance were lower in the psychoeducation group in the short term (n = 1400, RR 0.52 CI 0.40 to 0.67, NNT 11 CI 9 to 16). This finding holds for the medium and long term. Relapse appeared to be lower in psychoeducation group (n = 1214, RR 0.70 CI 0.61 to 0.81, NNT 9 CI 7 to 14) and this also applied to readmission (n = 206, RR 0.71 CI 0.56 to 0
This diploma thesis concentrates on problem posing from the students' point of view. Problem posing can be either seen as a teaching method which can be used in the class, or it can be used as a tool for researchers or teachers to assess the level of students' understanding of the topic. In my research, I compare three classes, one mathematics specialist class and two generalist classes, in their ability of problem posing. As an assessment tool it seemed that mathemathics specialists were abl...

International best-practice guidelines for the management of first-episode psychosis have recommended the provision of psychoeducation for multifamily groups. While there is ample evidence of their efficacy in multiepisode psychosis, there is a paucity of evidence supporting this approach specifically for first-episode psychosis. We sought to determine whether a six-week caregiver psychoeducation programme geared specifically at first-episode psychosis improves caregiver knowledge and attitudes.

Wechsler Intelligence Test for Children-IV core subtest scores of 472 children were cluster analyzed to determine if reliable and valid subgroups would emerge. Three subgroups were identified. Clusters were reliable across different stages of the analysis as well as across algorithms and samples. With respect to external validity, the Globally Low cluster differed from the other two clusters on Wechsler Individual Achievement Test-II Word Reading, Numerical Operations, and Spelling subtests, whereas the latter two clusters did not differ from one another. The clusters derived have been identified in studies using previous WISC editions. Clusters characterized by poor performance on subtests historically associated with the VIQ (i.e., VCI + WMI) and PIQ (i.e., POI + PSI) did not emerge, nor did a cluster characterized by low scores on PRI subtests. Picture Concepts represented the highest subtest score in every cluster, failing to vary in a predictable manner with the other PRI subtests.

Females care for individuals with chronic illness more commonly than males and have different attitudes to illness. Additionally, they experience greater burden and reduced quality of life, when compared to their male counterparts. Since knowledge has been shown to be related to burden, we sought to determine whether there were gender differences in knowledge acquisition during a six-week caregiver psychoeducation programme (CPP).

Multifactorial strategies that prevent or delay the onset or progress of cognitive decline and dementia are needed, and should include education regarding recognized risk factors. The current study sought to investigate whether older adults "at risk" of cognitive decline benefit from psychoeducation targeting healthy brain aging. 65 participants (mean age 64.8 years, SD 9.6) with a lifetime history of major depression; vascular risk as evidenced by at least one vascular risk factor; and/or subjective or objective memory impairment were allocated to weekly psychoeducation sessions or a waitlist control group. The small group sessions were conducted over ten weeks by a team of medical and allied health professionals with expertise in late-life depression and cognition. Sessions focused on modifiable risk factors for cognitive decline including vascular risk, diet, exercise, depression, anxiety and sleep disturbance, as well as providing practical strategies for memory and cognition. Both the psychoeducation and waitlist group completed a 20-item knowledge test at baseline and follow-up. Participants in the psychoeducation group were asked to complete follow-up self-report satisfaction questionnaires. Repeated measures ANOVA showed a significant interaction effect depicting improvements in knowledge associated with psychoeducation, corresponding to an improvement of 15% from baseline. Satisfaction data additionally showed that 92.3% of participants rated the program as "good" to "excellent", and over 90% suggested they would recommend it to others. A group-based psychoeducation program targeting healthy brain aging is effective in improving knowledge. Additionally, it is acceptable and rated highly by participants.
Full Text Available Example-based mesh deformation techniques produce natural and realistic shapes by learning the space of deformations from examples. However, skeleton-based methods cannot manipulate a global mesh structure naturally, whereas the mesh-based approaches based on a translational control do not allow the user to edit a local mesh structure intuitively. This paper presents an example-driven mesh editing framework that achieves both global and local pose manipulations. The proposed system is built with a surface deformation method based on a two-step linear optimization technique and achieves direct manipulations of a model surface using translational and rotational controls. With the translational control, the user can create a model in natural poses easily. The rotational control can adjust the local pose intuitively by bending and twisting. We encode example deformations with a rotation-invariant mesh representation which handles large rotations in examples. To incorporate example deformations, we infer a pose from the handle translations/rotations and perform pose space interpolation, thereby avoiding involved nonlinear optimization. With the two-step linear approach combined with the proposed multiresolution deformation method, we can edit models at interactive rates without losing important deformation effects such as muscle bulging.

Full Text Available Background: Cardiovascular heart disease still remains high in Indonesia. Various interventions have been implemented as an effort to deal with cardiovascular disease. However, little is known about intervention to reduce anxiety in patients with cardiovascular disease although anxiety is related to angina attack in this patient. Psychoeducation is considered effective in decreasing anxiety. Objective: To examine the effect of psychoeducation in decreasing anxiety in patients with coronary heart disease (CHD at the General Hospital of Semarang. Methods: This was a quasy experimental design with pretest posttest control group design. The study was conducted in the inpatient wards of the General Hospital of Semarang on January 17 until March 8, 2017. Fifty-six respondents were recruited using consecutive sampling, with 28 assigned in the experiment and control group. Hamilton Anxiety Rating Scale (HARS was used to measure anxiety levels. Paired t-test and Independent t-test were used for data analysis. Results: Paired test showed that there was a statistically significant effect of psychoeducation on anxiety level in the experiment group with p-value 0.001 (<0.05, and significant effect of given a brochure of CHD on the anxiety level in the control group with p-value 0.001 (<0.05. Independent t-test showed a statistically significant difference of anxiety level after intervention in the experiment and control group with p-value 0.001 (<0.05. The mean anxiety level in the experiment group (22.46 was lower than the mean anxiety level in the control group (41.54. Conclusion: Psychoeducation is effective in reducing anxiety levels in patients with CHD. It is suggested that psychoeducation can be used as one of nursing intervention in an effort to reduce anxiety in patients with CHD.

Patients with coronary heart disease are at high risk for mental health disorders, such as depression and anxiety. Psychoeducation is a well-known intervention for psychiatric patients, but its use has been limited in other health conditions, such as coronary heart disease. The aim of this study was to evaluate the effect of psychoeducation on mental health in coronary heart disease patients. This randomized clinical trial included 70 patients with coronary heart disease at Shahid Beheshti hospital, in Kashan, Iran, in 2014. The patients were randomly assigned into two groups: the experimental group, which received eight sessions of psychoeducation, and the control group, which received routine care. Data were collected with the Goldberg mental health questionnaire (GHQ) and were analyzed using independent and paired t-tests performed with SPSS version 16. The means of overall GHQ scores were significantly decreased post-test in the intervention group, and the differences between the two groups were statistically significant in the overall GHQ scores (P = 0.0001). A significant difference was observed between the mean GHQ scores of the intervention group prior to and after the psychoeducational program (PEP) intervention (30 ± 4.66 vs. 20.50 ± 3.30) (P = 0.0001). No significant changes were observed in the control group pre- and post-test (P = 0.07). Psychoeducation resulted in improved mental health in patients with coronary heart disease. Therefore, it is recommended that this approach be performed as a complementary, effective, non-invasive, low-cost nursing intervention to reduce psychological problems in these patients.

Research has shown that overgeneral autobiographical memory (OGM) is a valid predictor for the course of depression. It is not known, however, whether OGM also moderates information uptake and consolidation in a psychoeducation program to prevent stress, anxiety and depression. The present study was designed to investigate whether the Autobiographical Memory Test (AMT; Williams, & Broadbent, 1986) is a valid predictor for the actual unfolding of skills learned through psychoeducation. The questionnaire included primarily the AMT and the Stress Anxiety Depression Means-Ends Problem Solving Questionnaire (SAD-MEPS). It was filled in prior to and after the psychoeducational course by 23 participants. Correlations were calculated for the AMT at baseline and the differences between the pre and post measurements on the SAD-MEPS. Significant correlations were observed between the number of specific responses and the changes in the number of relevant means (r = .49, p < .01). The sample size was rather small, but several checks were able to reduce the chance of spurious findings. These findings may have important implications for the guidance to and the setup of psychoeducational interventions. Suggestions include screening and memory specificity training prior to course commencement. Copyright © 2011 Elsevier Ltd. All rights reserved.
The aim of the study was to examine the efficiency of psycho-education of candidates for the IVF in stress, anxiety and depression decreasing, and the impact of the psycho educative techniques on the successfulness of the treatment. A random sample of 64 candidates for IVF treatment is divided in two groups: control group without psycho-education (32 candidates) and intervention group of 32 candidates included in psycho-education. Depression, anxiety and stress scale (DASS) was used as a psychometric test. It's a multiple choice, self-reported inventory for measuring the levels of stress, anxiety and severity of depression. For statistic evaluation SPSS software was used. The study shows that the intervention group included in psycho-education has a signifycantly lower scores on stress (t = 3.201, p stress decreasing, as well as significant impact in the successfulness of the treatment. It was pointed out that psychological support of candidates for IVF is important for the lessening of the negative emotional reactions of candidates as well as for the successfulness of the treatment.

This study aimed to examine the significance of intervention to improve medication adherence in long-term inpatients by providing psychoeducation and then elucidating the effects of this training in terms of patient knowledge and attitudes. Subjects were patients who had been hospitalized for more than 1 year after being admitted to a psychiatric hospital, had been diagnosed as F2 (schizophrenia, schizoaffective disorder) according to the International Classification of Diseases, 10th Edition, and were capable of verbal communication. Patients suspected of having dementia were excluded. Items surveyed were patient background, prescriptions, Global Assessment of Functioning (GAF) score, Drug Attitude Inventory-10 (DAI-10) score, and Knowledge of Illness and Drugs Inventory (KIDI) score. The amount of medication taken and GAF, DAI-10, and KIDI scores were evaluated within 1 week of starting psychoeducation and within 1 week of completing psychoeducation. The Wilcoxon signed-rank test and McNemar test was used to compare scores before and after intervention. The mean overall KIDI score increased significantly, and the mean overall DAI-10 score improved significantly after intervention. Furthermore, the mean overall KIDI score of very long-term inpatients with schizophrenia and schizoaffective disorder increased significantly after intervention. Psychoeducation produced improvement in some areas of knowledge and attitudes towards medication among long-term inpatients. These results demonstrate that psychoeducation has an effect on long-term inpatients that is similar to the effect observed in earlier studies on patients leading community lives, including patients who have just been admitted or discharged and patients attending day care or outpatient visits.

In this paper, we propose a pose editing and animation method for triangulated surfaces based on a user controlled partitioning of the model into deformable parts and rigid parts which are denoted handles. In our pose editing system, the user can sculpt a set of poses simply by transforming...... the handles for each pose. Using Laplacian editing, the deformable parts are deformed to match the handles. In our animation system the user can constrain one or several handles in order to define a new pose. New poses are interpolated from the examples poses, by solving a small non-linear optimization...... problem in order to obtain the interpolation weights. While the system can be used simply for building poses, it is also an animation system. The user can specify a path for a given constraint and the model is animated correspondingly....

Updated and expanded, this second edition satisfies the same philosophical objective as the first -- to show the importance of problem posing. Although interest in mathematical problem solving increased during the past decade, problem posing remained relatively ignored. The Art of Problem Posing draws attention to this equally important act and is the innovator in the field. Special features include: * an exploration ofthe logical relationship between problem posing and problem solving * a special chapter devoted to teaching problem posing as a separate course * sketches, drawings, diagrams, and cartoons that illustrate the schemes proposed * a special section on writing in mathematics.

Utilizing information obtained through an international survey and existing literature, patterns in the practices, research, and preparation of professionals who deliver psychoeducational services to children and youth in six Oriental countries (i.e., China, Hong Kong(1), Japan, the Philippines, Taiwan, and Thailand) are described. Services are provided by many professional groups. While few formal programs exist for the preparation of psychologists to work in schools, those providing such services have at least a bachelor's degree. Services commonly provided include assessment, vocational and educational guidance, counseling, parent education, and teaching. School psychological services generally are not governed by legislation or professional standards. Research tends to be applied and directed toward the construction and translations of tests and toward the needs of the mentally retarded, learning disabled, and behaviorally disordered. Ten major problems creating barriers for the delivery of psychoeducational services are identified. Three suggestions to help resolve these problems are offered.

Research on beneficial consequences of yoga focuses on the effects of yogic breathing and meditation. Less is known about the psychological effects of performing yoga postures. The present study investigated the effects of yoga poses on subjective sense of energy and self-esteem. The effects of yoga postures were compared to the effects of 'power poses,' which arguably increase the sense of power and self-confidence due to their association with interpersonal dominance (Carney et al., 2010). The study tested the novel prediction that yoga poses, which are not associated with interpersonal dominance but increase bodily energy, would increase the subjective feeling of energy and therefore increase self-esteem compared to 'high power' and 'low power' poses. A two factorial, between participants design was employed. Participants performed either two standing yoga poses with open front of the body ( n = 19), two standing yoga poses with covered front of the body ( n = 22), two expansive, high power poses ( n = 21), or two constrictive, low power poses ( n = 20) for 1-min each. The results showed that yoga poses in comparison to 'power poses' increased self-esteem. This effect was mediated by an increased subjective sense of energy and was observed when baseline trait self-esteem was controlled for. These results suggest that the effects of performing open, expansive body postures may be driven by processes other than the poses' association with interpersonal power and dominance. This study demonstrates that positive effects of yoga practice can occur after performing yoga poses for only 2 min.

To evaluate the effectiveness of a psychoeducational programme in enhancing motivation to change alcohol-addictive behaviour. The prevalence of alcohol abuse has increased over the past 10 years, and the age of initial alcohol use has decreased gradually in Taiwan. Alcohol dependence is one of the leading causes of disability and has led to increases in the incidence of crime and violence, with alcohol abuse identified as a problem in society. A quasi-experimental design with nonequivalent pre/post-testing was used. Alcohol-dependent inpatients undergoing alcohol treatment were selected from the psychiatric ward of a teaching hospital in northern Taiwan. The effectiveness of the psychoeducational programme in enhancing motivation to change alcohol-addictive behaviour was evaluated with the Severity of Alcohol Dependence Data Questionnaire and the Stages of Change Readiness and Treatment Eagerness Scale. In total, 24 and 51 participants were recruited to the experimental and control groups, respectively, for the baseline survey, and 14 and 17 were in the final survey, respectively. After adjustment for baseline survey scores, the experimental group showed significantly greater increases in recognition and ambivalence relative to those observed in the control group. The results not only showed that the psychoeducational programme was effective in reinforcing addicted inpatients' motivation for changing their drinking behaviour but also provided clinical nurses with practical methods via which to enhance patient motivation. The psychoeducational programme could assist clinical nurses in helping alcohol-dependent patients to recognise the nature of their problematic drinking; increase participants' ambivalence towards their drinking behaviour, leading to the contemplation of change; and strengthen the possibility that they will change their addictive behaviour. © 2017 John Wiley & Sons Ltd.

Despite high levels of burden and distress among families with a member who has borderline personality disorder (BPD), only two BPD specific family psychoeducation groups have been empirically evaluated. Neither of these is designed specifically for the family and friends of young people who are presenting early in the course of BPD. This study aimed to evaluate Making Sense of Borderline Personality Disorder (MS-BPD), a three-session, developmentally tailored, manualised psychoeducational group for the family and friends of youth with BPD features. The study employed a pre- and post-intervention, repeated measures design. Twenty-three participants completed self-report measures assessing for family burden, psychological distress, and knowledge about personality disorder. Demographic data were collected for the group participants and for their associated young person with BPD. Paired-samples t -tests were conducted to evaluate the effect of the MS-BPD intervention on participants' burden, distress and personality disorder knowledge. At the completion of session three (day 15), group participants reported significantly decreased subjective burden and increased personality disorder knowledge. Objective burden and distress remained unchanged. Family and friends of young people with BPD features experienced subjective, but not objective, benefit from attending a brief group-based psychoeducation intervention. Longer follow-up is likely to be required to detect behavioural change. The current findings support proceeding to a randomised controlled trial of MS-BPD.

This is a qualitative research concerning on students’ creativity on problem posing task. The study aimed at describing the students’ creative thinking ability to pose the mathematics problem in structured situations with varied condition of given problems. In order to find out the students’ creative thinking ability, an analysis of mathematics problem posing test based on fluency, novelty, and flexibility and interview was applied for categorizing students’ responses on that task. The data analysis used the quality of problem posing and categorized in 4 level of creativity. The results revealed from 29 secondary students grade 8, a student in CTL (Creative Thinking Level) 1 met the fluency. A student in CTL 2 met the novelty, while a student in CTL 3 met both fluency and novelty and no one in CTL 4. These results are affected by students’ mathematical experience. The findings of this study highlight that student’s problem posing creativity are dependent on their experience in mathematics learning and from the point of view of which students start to pose problem.

Depressive disorders are one of the leading components of the global burden of disease with a prevalence of up to 14% in the general population. Numerous studies have demonstrated that pharmacotherapy combined with non-pharmacological measures offer the best treatment approach. Psycho-education as an intervention has been studied mostly in disorders such as schizophrenia and dementia, less so in depressive disorders. The present study aimed to assess the impact of psycho-education of patients and their caregivers on the outcome of depression. A total of 80 eligible depressed subjects were recruited and randomised into 2 groups. The study group involved an eligible family member and all were offered individual structured psycho-educational modules. Another group (controls) received routine counselling. The subjects in both groups also received routine pharmacotherapy and counselling from the treating clinician and were assessed at baseline, 2, 4, 8, and 12 weeks using the Hamilton Depression Rating Scale (HDRS), Global Assessment of Functioning (GAF), and Psychological General Well-Being Index (PGWBI). Results from both groups were compared using statistical methods including Chi-square test, Fisher's exact test, Student's t test, Pearson's correlation coefficient, as well as univariate and multiple regression analyses. Baseline socio-demographic and assessment measures were similar in both groups. The study group had consistent improvement in terms of outcome measures with HDRS, GAF, and PGWBI scores showing respective mean change of -15.08, 22, and 60 over 12 weeks. The comparable respective changes in the controls were -8.77, 18.1, and 43.25. Structured psycho-education combined with pharmacotherapy is an effective intervention for people with depressive disorders. Psycho-education optimises the pharmacological treatment of depression in terms of faster recovery, reduction in severity of depression, and improvement in subjective wellbeing and social functioning.

To evaluate the efficacy of a psychoeducation program for parents of children with ADHD in enhancing adherence to pharmacological treatment and improving clinical symptoms. We developed a psychoeducation program based on the theory of planned behavior (TPB). Eighty-nine children with ADHD were cluster randomly assigned for their families to receive 3 months of well-structured psychoeducation (intervention group, n=44) or only general clinical counseling (control group, n=45). Parents in the intervention group were given an expert lecture (with slides and a parent manual), attended two expert-guided parent group sessions, and were invited to join a professional-guided online community. Measurement of parents' knowledge about ADHD, components of the TPB model, and child ADHD symptoms were taken before and after intervention. Medication adherence was assessed thoroughly at the end of the first and third months. Satisfaction with the psychoeducation program was assessed only in the intervention group. Two-independent-samples t-test, ANOVA, and chi-square test were employed to compare differences between groups. Compared to the control group, medication adherence in the intervention group was significantly higher after 1 and 3 months (97.7% intervention vs 75.6% control, P=0.002, and 86.4% intervention vs 53.3% control, P=0.001, respectively). Accordingly, the ADHD rating scale scores were lower in the intervention group than the control group after intervention (33.7±5.4 vs 45.1±7.9, P=0.008). Greater improvements in parents' knowledge about ADHD and many components of the TPB model were observed in the intervention group, especially increased intention to adhere to medication, compared to the control group (P<0.001). This psychoeducation program had a positive impact on both medication adherence and clinical symptoms of ADHD children. It could be considered as a potential beneficial supplement to clinical practice.

Binge eating disorder (BED) is associated with several psychological and medical problems, such as obesity. Approximately 30% of individuals seeking weight loss treatments present binge eating symptomatology. Moreover, current treatments for BED lack efficacy at follow-up assessments. Developing mindfulness and self-compassion seem to be beneficial in treating BED, although there is still room for improvement, which may include integrating these different but complimentary approaches. BEfree is the first program integrating psychoeducation-, mindfulness-, and compassion-based components for treating women with binge eating and obesity. To test the acceptability and efficacy up to 6-month postintervention of a psychological program based on psychoeducation, mindfulness, and self-compassion for obese or overweight women with BED. A controlled longitudinal design was followed in order to compare results between BEfree (n = 19) and waiting list group (WL; n = 17) from preintervention to postintervention. Results from BEfree were compared from preintervention to 3- and 6-month follow-up. BEfree was effective in eliminating BED; in diminishing eating psychopathology, depression, shame and self-criticism, body-image psychological inflexibility, and body-image cognitive fusion; and in improving obesity-related quality of life and self-compassion when compared to a WL control group. Results were maintained at 3- and 6-month follow-up. Finally, participants rated BEfree helpful for dealing with impulses and negative internal experiences. These results seem to suggest the efficacy of BEfree and the benefit of integrating different components such as psychoeducation, mindfulness, and self-compassion when treating BED in obese or overweight women. The current study provides evidence of the acceptability of a psychoeducation, mindfulness, and compassion program for binge eating in obesity (BEfree); Developing mindfulness and self-compassionate skills is an effective way of

As a result of the editors' collaborative teaching at Harvard in the late 1960s, they produced a ground-breaking work -- The Art Of Problem Posing -- which related problem posing strategies to the already popular activity of problem solving. It took the concept of problem posing and created strategies for engaging in that activity as a central theme in mathematics education.

Patients undergoing coronary artery bypass graft surgery often experience a range of problems and symptoms such as immobility, pain and insufficient sleep. Results from trials investigating testing in-hospital physical exercise or psychological intervention have been promising. However, no randomized clinical trials have tested a comprehensive rehabilitation programme consisting of both physical exercise and psycho-education in the early rehabilitation phase. The aims of the present SheppHeart pilot randomized clinical trial were to evaluate the feasibility of patient recruitment, patient acceptance of the intervention, safety and tolerability of the intervention. Sixty patients admitted for coronary artery bypass graft were randomized 1:1:1:1 to: 1) physical exercise plus usual care, or 2) psycho-educational intervention plus usual care, or 3) physical exercise and psycho-educational plus usual care, or 4) usual care alone during a four week period after surgery. The acceptability of trial participation was 67% during the three month recruitment period. In the physical exercise groups, patients complied with 59% of the total expected training sessions during hospitalization. Nine patients (30%) complied with >75% and nine patients (30%) complied with 50% of the planned exercise sessions. Eleven patients (42%) participated in ⩾75% of the four consultations and six patients (23%) participated in 50% of the psycho-educational programme. Comprehensive phase one rehabilitation combining physical exercise and psycho-education in coronary artery bypass graft patients shows reasonably high inclusion, feasibility and safety. © The European Society of Cardiology 2015.

Improving treatment adherence to immunosuppressive agents could have positive effects on the morbidity and mortality of kidney transplant recipients. Our objective was to determine whether psychoeducational intervention aimed at improving treatment adherence also could improve 10-year kidney allograft survival rates. A randomized open-label study compared a group who received psychoeducational intervention (n = 55) with a control group (n = 55), with all patients being kidney transplant recipients in the Department of Nephrology and Organ Transplantation (University Hospital, Toulouse, France). Psychoeducational intervention comprised 8 weekly sessions provided by multidisciplinary teams. Patients were included between 2002 and 2003. The primary endpoint was allograft survival at 10 years (ie, by 2012). A failed allograft or death with a functioning allograft was considered an event. Mean overall allograft survival rate at 10 years was 78.2% (95% confidence interval, 70.5-25.3). In the control group, 48 patients (43.6%) still had a functioning graft at 10 years versus 38 patients (34.5%) in the psychoeducational intervention group (P = .02). However, a log-rank test did not find any significant difference in allograft survival between the groups (P = .06). In multivariate analyses (Cox model), no factor was significantly associated with allograft survival at 10 years. After an initial 6-month observational adherence survey, there was no benefit to kidney allograft survival at 10 years after the psychoeducational intervention, which had aimed to improve patient adherence to treatment with immunosuppressive agents. This might be related to the fact that booster interventions are needed (eg, on a yearly basis).

We present a novel method for human action recognition (HAR) based on estimated poses from image sequences. We use 3D human pose data as additional information and propose a compact human pose representation, called a weak pose, in a low-dimensional space while still keeping the most discriminative information for a given pose. With predicted poses from image features, we map the problem from image feature space to pose space, where a Bag of Poses (BOP) model is learned for the final goal of HAR. The BOP model is a modified version of the classical bag of words pipeline by building the vocabulary based on the most representative weak poses for a given action. Compared with the standard k-means clustering, our vocabulary selection criteria is proven to be more efficient and robust against the inherent challenges of action recognition. Moreover, since for action recognition the ordering of the poses is discriminative, the BOP model incorporates temporal information: in essence, groups of consecutive poses are considered together when computing the vocabulary and assignment. We tested our method on two well-known datasets: HumanEva and IXMAS, to demonstrate that weak poses aid to improve action recognition accuracies. The proposed method is scene-independent and is comparable with the state-of-art method.

Severe mental illness causes suffering for the patient as well as the patient's immediate family. The Swedish National Board of Health and Welfare has recommended the implementation of multifamily psychoeducation in order to assist patient and family in the recovery process. The aim of this study was to determine how introducing multifamily psychoeducation in Sweden has been viewed by professionals. Semi-structured interviews were conducted with 11 service providers, who were involved in evaluating multifamily psychoeducation. Our main findings fell under the headings of defensive culture and unsuitable model. Resistance to introducing the new intervention was found on multiple levels. The model proposed was considered too rigid for both the target group and the organizations because it could not be adjusted to the needs of patients, families, or facilitators. Despite good evidence for the effectiveness of the intervention, there were difficulties introducing the multifamily psychoeducation model in clinical practice. The feasibility of an intervention needs to be evaluated before adopting it as a national guideline.

Full Text Available Introduction: Family members often play a vital role as caregivers in the lives of individuals with schizophrenia. Results of the studies showed that family invironment is the most important determinint of patients outcomes like as quality of life, relapse, adherence. This study aimed to determine the effect of group psychoeducational programme on attitude towards mental illness in families of patients with schizophrenia. Methods: In this quasi-experimental study, 74 families who have schizophrenic patients hospitalized in psychiatric wards during sampling were selected by convenience sampling method. Then the sample was randomly assigned to experimental and control groups. The families of experimental group received 8 continuous 90-minute 3 times a week psychoeducational sessions. Family attitude towards mental illness was measured using the questionnaire of Opinion about Mental Illnesses (OMI before and after intervention. Data analysis was conducted using 2 test, independent t-test, and paired t-test on SPSS software version 13. Results: The results showed that majority of the families had negative attitude towards mental illness (88.90%. In addition, the results showed that there was significant difference between different dimensions of attitude towards mental illness before and after psychoeducation in the experimental group. The mean score of families' post-test in the experimental group increased compared to control group 108.86 (14.9, vs. 88.86 (7.5. Conclusion: The results of this study indicate that psychoeducation improves family attitude towards mental illness. Training methods like group psych education for the families of mental patients can be effective on their attitudes towards mental illness.

One rather fundamental question concerning supergravity remains unresolved: Is supergravity a well-posed field theory? That is, does a set of certain (Cauchy) data specified on some initial spacelike surface determine a unique, causally propagating spacetime solution of the supergravity field equations (at least in some finite neighborhood of the initial surface)? In this paper, the authors give a very brief report on work directed towards answering this question. (Auth.)

To examine the effects of therapeutic play intervention on outcomes of children undergoing day surgery, and to highlight the importance of parental involvement in the psychoeducational preparation of children for surgery. A randomized controlled trial, two group pre-test and repeated post-test, between subjects design was employed. Hong Kong Chinese children (7-12 years of age; n=203) admitted for elective surgery in a day surgery unit, along with their parents during a 13-month period, were invited to participate in the study. By using a simple complete randomization method, 97 of children with their parents were assigned to the experimental group receiving therapeutic play intervention, and 106 children with their parents were assigned to the control group receiving routine information preparation. The results showed that both children and their parents in the experimental group reported lower state anxiety scores in pre- and post-operative periods. Children in the experimental group exhibited fewer instances of negative emotional behaviors and parents in the experimental group reported greater satisfaction. The results, however, find no differences in children's post-operative pain between the two groups. The study provides empirical evidence to support the effectiveness of using therapeutic play intervention and the importance of parental involvement in the psychoeducational preparation of children for surgery. The findings heighten the awareness of the importance of integrating therapeutic play and parental involvement as essential components of holistic and quality nursing care to prepare children for surgery.

The main purpose of our psycho-educational groups was to help women with breast cancer learn how to cope with the physical, emotional, and lifestyle changes associated with cancer as well as with medical treatments that can be painful and traumatic. With this study, we wanted to detect the effects that group action had on the women who participated in it. We studied a total of 97 patients who participated in 13 psycho-education groups. The whole sample was female patients who had breast cancer with no recurrence or metastases. All patients were evaluated with the Hospital Anxiety and Depression Scale (HADS) and the Body Image Scale (BIS). We found no significant effect on anxiety and body image for the brief psycho-educational group for women with breast cancer in this study. It is possible to highlight a statistical difference (Table 3) and hence an improvement between the results of the HADS depression test at T0 (first evaluation at the first meeting) and T1 (retest in the final meeting). The tests did not show a significant effect on anxiety and body image perception, but the patients reported that the psycho-educational group was an important intervention for their life. Outcome measurement is more complex in psychosocial research because many variables come into play and each phase of treatment is characterized by different types of problems for the patient: physical, relational and psychological aspects are involved.

Many people with severe mental illness (SMI) have siblings. Siblings are often both natural agents to promote service users' recovery and vulnerable to mental ill health due to the negative impact of psychosis within the family. Despite a wealth of research evidence supporting the effectiveness of psychoeducation for service users with SMI and their family members, in reducing relapse and promoting compliance with treatment, siblings remain relatively invisible in clinical service settings as well as in research studies. If psychoeducational interventions target siblings and improve siblings' knowledge, coping with caring and overall wellbeing, they could potentially provide a cost-effective option for supporting siblings with resulting benefits for service users' outcomes. To assess the effectiveness of psychoeducation compared with usual care or any other intervention in promoting wellbeing and reducing distress of siblings of people affected by SMI.The secondary objective was, if possible, to determine which type of psychoeducation is most effective. We searched the Cochrane Schizophrenia Group Trials Register and screened the reference lists of relevant reports and reviews (12th November 2013). We contacted trial authors for unpublished and specific data on siblings' outcomes. All relevant randomised controlled trials focusing on psychoeducational interventions targeting siblings of all ages (on their own or amongst other family members including service users) of individuals with SMI, using any means and formats of delivery, i.e. individual (family), groups, computer-based. Two review authors independently screened the abstracts and extracted data and two other authors independently checked the screening and extraction process. We contacted authors of trials to ascertain siblings' participation in the trials and seek sibling-specific data in those studies where siblings' data were grouped together with other participants' (most commonly other family members

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.
Full Text Available The studies in expressed emotions allowed establishing a pattern in educational and psychoeducative interventions within the families of schizophrenic patients. In this paper, the author synthesises his research developed in expressed emotions of the chronic patient's relatives. The author refers the importance of the relative's cognitive variables about mental representation of the patient and his disease. These variables are studied through the attributions made about the patient's personality and causes of disease. Other cognitive variables are analysed, relying to the conceptualisation in family psycho educative intervention, such as, transactional games, family conflicts and parental relationship style. The evaluation of the relatives and families is considered as being part of the process of family psycho-educative intervention.
Full Text Available Abstract Background Bipolar disorders affect between 3–5% of the population and are associated with considerable lifelong impairment. Since much of the morbidity associated with bipolar disorder is caused by recurrent depressive symptoms, which are often only poorly responsive to antidepressants, there is a need to develop alternative, non-pharmacological interventions. Psychoeducational interventions have emerged as promising long-term therapeutic options for bipolar disorder. Methods/design The study is an exploratory, individually randomised controlled trial. The intervention known as 'Beating Bipolar' is a psychoeducational programme which is delivered via a novel web-based system. We will recruit 100 patients with a diagnosis of DSM-IV bipolar disorder (including type I and type II currently in clinical remission. The primary outcome is quality of life. This will be compared for those patients who have participated in the psychoeducational programme with those who received treatment as usual. Quality of life will be assessed immediately following the intervention as well as 10 months after randomisation. Secondary outcomes include current depressive and manic symptoms, number of episodes of depression and mania/hypomania experienced during the follow-up period, global functioning, functional impairment and insight. An assessment of costs and a process evaluation will also be conducted which will explore the feasibility and acceptability of the intervention as well as potential barriers to effectiveness. Discussion Bipolar disorder is common, under-recognised and often poorly managed. It is a chronic, life-long, relapsing condition which has an enormous impact on the individual and the economy. This trial will be the first to explore the effectiveness of a novel web-based psychoeducational intervention for patients with bipolar disorder which has potential to be easily rolled out to patients.

Mood disorders related behaviors are imposed on family members and influence the family's mental atmosphere and level of quality of life. Therefore, the researchers decided to study the effect of group psycho-educational program on the quality of life in families of patients with mood disorders. This is a two-group interventional study conducted on 32 members of families of the patients with mood disorders selected through random sampling. A group psycho-educational program was conducted in ten 90-min sessions (twice a week) for the study group. (World Health Organization's Quality of Life-BREF WHOQOL-BREF) questionnaire was adopted in the study and was filled before, immediately after, and 1 month after the intervention. Independent t-test showed a significant difference in the scores of quality of life in the domains of mental health, social communications, and environmental health, immediately after and 1 month after intervention in the study group compared to the control group. Repeated measure analysis of variance showed a significant increase in the mean scores of quality of life in the study group. The results showed that the impact of group psycho-educational program is observed in the prevention of reduction in quality of life and its promotion in the families of patients with mood disorders.

Negative effects of stress have pose one of the major threats to the health and economic well being of individuals independently of age and cultural background. Nevertheless, the term "stress" has been globally used unlinked from scientificevidence-based meaning. The discrepancies between scientific and public stress knowledge are focus of concern and little is know about it. This is relevant since misconceptions about stress may influence the effects of stress-management psychoeducational programs and the development of best practices for interventions. The study aimed to analyze stress knowledge among the Canadian and Brazilian general public and to determine the extent to which scientific and popular views of stress differ between those countries. We evaluated 1156 healthy participants between 18 and 88 years of age recruited from Canada (n = 502) and Brazil (n = 654). To assess stress knowledge, a questionnaire composed of questions regarding stress concepts ("stress is bad" versus "stress-free life is good") and factors capable of triggering the stress response ("novelty, unpredictability, low sense of control and social evaluative threat versus "time pressure,work overload, conflict, unbalance and children") was used. Both Canadian and Brazilian participants showed misconceptions about stress and the factors capable of triggering a stress response. However, the rate of misconceptions was higher in Brazil than in Canada (p stress science and its variance according to a country's society. Psychoeducational programs and vulnerability of stress-related disorder are discussed.

In the computer research area, facial expression recognition is a hot research problem. Recent years, the research has moved from the lab environment to in-the-wild circumstances. It is challenging, especially under extreme poses. But current expression detection systems are trying to avoid the pose effects and gain the general applicable ability. In this work, we solve the problem in the opposite approach. We consider the head poses and detect the expressions within special head poses. Our work includes two parts: detect the head pose and group it into one pre-defined head pose class; do facial expression recognize within each pose class. Our experiments show that the recognition results with pose class grouping are much better than that of direct recognition without considering poses. We combine the hand-crafted features, SIFT, LBP and geometric feature, with deep learning feature as the representation of the expressions. The handcrafted features are added into the deep learning framework along with the high level deep learning features. As a comparison, we implement SVM and random forest to as the prediction models. To train and test our methodology, we labeled the face dataset with 6 basic expressions.

A robust face pose estimation approach is proposed by using face shape statistical model approach and pose parameters are represented by trigonometric functions. The face shape statistical model is firstly built by analyzing the face shapes from different people under varying poses. The shape alignment is vital in the process of building the statistical model. Then, six trigonometric functions are employed to represent the face pose parameters. Lastly, the mapping function is constructed between face image and face pose by linearly relating different parameters. The proposed approach is able to estimate different face poses using a few face training samples. Experimental results are provided to demonstrate its efficiency and accuracy.

The aim of this study was to investigate the long term efficacy of family-focused cognitive behaviour therapy (CBT) compared with psycho-education in improving school attendance and other secondary outcomes in adolescents with chronic fatigue syndrome (CFS). A 24 month follow-up of a randomised controlled trial was carried out. Participants received either 13 one-hour sessions of family-focused CBT or four one-hour sessions of psycho-education. Forty-four participants took part in the follow-up study. The proportion of participants reporting at least 70% school attendance (the primary outcome) at 24 months was 90% in CBT group and 84% in psycho-education group; the difference between the groups was not statistically significant (OR = 1.29, p = 0.80). The proportion of adolescents who had recovered in the family-focused CBT group was 79% compared with 64% in the psycho-education, according to a definition including fatigue and school attendance. This difference was not statistically significant (Fisher's exact test, p = 0.34). Family-focused CBT was associated with significantly better emotional and behavioural adjustment at 24 month follow-up compared to psycho-education, as reported by both adolescents (F = 6.49, p = 0.02) and parents (F = 4.52, P = 0.04). Impairment significantly decreased in both groups between six and 24 month follow-ups, with no significant group difference in improvement over this period. Gains previously observed for other secondary outcomes at six month follow-up were maintained at 24 month follow-up with no further significant improvement or group differences in improvement. In conclusion, gains achieved by adolescents with CFS who had undertaken family-focused CBT and psycho-education generally continued or were maintained at two-year follow-up. The exception was that family-focused CBT was associated with maintained improvements in emotional and behavioural difficulties whereas psycho-education was associated with

A purposive sample of African American Senior Companions ( N = 23) participated in a 5-day, 20-hour psychoeducational training designed to address the unique cultural needs of African American dementia caregivers. Previous studies have not utilized lay caregiver volunteers such as Senior Companions in dementia research in the United States. Pre- and post-tests were administered to determine whether African American Senior Companions increased their knowledge of Alzheimer's disease after participating in the Senior Companion Program Plus. Results from both the quantitative and qualitative data suggest that participants improved their understanding of Alzheimer's disease. Findings from the Senior Companion Program Plus pilot warrant further study for its potential as cost effective, culturally tailored training for Senior Companions who serve persons with dementia and their family caregivers.
Full Text Available Introduction: Suicide is the second leading cause of death for the university aged population globally. A significant proportion of students with suicidal ideation or behaviours do not seek professional help. Few primary suicide prevention programs have specifically targeted help seeking for suicidal ideation or behaviours among university students. Methods: This study reported the development and pilot test of a brief, two-module online psychoeducational program (ProHelp that aimed to encourage help seeking for suicidal ideation and behaviours among university students. The program consists of two five-minute modules that address the risk factors and warning signs of suicide, stigmatising attitudes, and perceived barriers to help seeking. 156 Chinese university students and 101 Australian university students were recruited to evaluate the effectiveness of this program at post-test and one-month follow-up. Participants were randomly assigned to the psychoeducational program or an attention control program. Results: Of the Chinese and Australian students who were randomised into the study, around 50% completed the twoday posttest survey, and 30% completed the one-month followup survey. Although no significant difference was found between the control and experimental group on professional help-seeking beliefs and intentions, both groups' help-seeking attitudes increased during the study (p=0.003 for the posttest survey, and p=0.008 for the followup survey. The experimental group in both countries demonstrated a significant improvement in suicide literacy at the post-test survey (p=0.015 compared to control. Qualitative feedback indicated that the ProHelp program was user-friendly, clear, and helpful. Conclusions: This study provides initial evidence that a brief online psychoeducational program could enhance university students' suicide literacy in both China and Australia. It also suggests that increasing suicide literacy might not be

Adherence to Highly Active Antiretroviral Therapy (HAART) is the main prognostic factor associated with HIV disease progression and death. The aim was to evaluate the effectiveness of a psycho-educational program to promote adherence to HAART in HIV patients. A longitudinal study (n = 102) over 9 months in an Infectious Diseases Hospital was carried out. Adherence to HAART was measured with standardized scales and values of viral load. Two groups were defined: adherents and non-adherents. In the latter, a psycho-educational program was implemented and 6 months later measured adherence to HAART. Knowledge about the infection, CD4 T lymphocytes and HIV-ribonucleic acid values were measured before and after this program. The sample was predominantly male (70%), heterosexual (78%), with a mean age of 49 (SD = 12.7) years, and 48% of participants were not adhering to HAART. After the program, non-adherence decreased to 21.6%. Knowledge about the infection increased from 79 to 97%. A significant increase in CD4 T lymphocytes (mean 540-580) and a decrease in viral load (mean 5411-3052) were observed, the latter of statistical significance. This program seems to be feasible and efficient, improving adherence to HAART.

The inference algorithm consists of two components: 1) Detecting top candidates for the pose templates, and 2) computing the sequence of pose templates. Both are done by dynamic programming or, more precisely, beam search. In experiments, we demonstrate that this method is capable of discovering salient poses of actions as well as interactions with contextual objects. We test our method on several public action data sets and a challenging outdoor contextual action data set collected by ourselves. The results show that our model achieves comparable or better performance compared to state-of-the-art methods.

Feasibility testing of a psychoeducational method -The Affect School and Script Analyses (ASSA) - in a Swedish primary care setting. Exploring associations between psychological, and medically unexplained physical symptoms (MUPS). Pilot study. Three Swedish primary care centers serving 20,000 people. 8 weekly 2-hour sessions with a 5-7 participant group led by two instructors - followed by 10 individual hour-long sessions. Thirty-six patients, 29 women (81%), on sick-leave due to depression, anxiety, or fibromyalgia. Feasibility in terms of participation rates and expected improvements of psychological symptoms and MUPS, assessed by self-report instruments pre-, one-week post-, and 18 months post-intervention. Regression coefficients between psychological symptoms and MUPS. The entire 26-hour psychoeducational intervention was completed by 30 patients (83%), and 33 patients (92%) completed the 16-hour Affect School. One-week post-intervention median test score changes were significantly favorable for 27 respondents, with p 80% participation rates, and clear improvements of self-assessed psychological symptoms and MUPS. The ASSA intervention thus showed adequate feasibility in a Swedish primary care setting. Key Points A pilot study of a psychoeducational intervention - The Affect School and Script Analyses (ASSA) - was performed in primary care • The intervention showed feasibility for patients on sick-leave due to depression, anxiety, or fibromyalgia • 92% completed the 8 weeks/16 hours Affect School and 83% completed the entire 26-hour ASSA intervention • 9 of 11 self-reported measures improved significantly one-week post intervention • 7 of 11 self-reported measures improved significantly 18 months post-intervention.

The aim of the study was to examine whether the efficacy of psychoeducation in patients with schizophrenia is dependent on their cognitive performance and if a preceding cognitive training can enhance the therapeutic effects of psychoeducation. A total of 116 inpatients were randomly assigned to either a standardized cognitive training (COGPACK) or to routine occupational therapy, followed by a psychoeducational group program of 8 sessions within 4 weeks for all study patients. The effects of cognitive training and psychoeducation were assessed directly afterwards and in a follow-up after 9 months. The patient knowledge and compliance improved. Neurocognition and especially memory acquisition significantly predicted illness knowledge after psychoeducation, whereas psychopathology did not. No differential effects of the COGPACK training were found. After 9 months 75% of the patients showed a very good compliance and the readmission rate was 18%. The results were comparable under both study conditions. Besides baseline illness knowledge neurocognition was the only significant predictor for illness knowledge after psychoeducation. Patients with cognitive deficits can profit from psychoeducation in the long run as well. In future it should be examined whether a modified cognitive training program could achieve a faster improvement of the illness knowledge.

How we conceptualize mental health conditions is important as it impacts on a wide range of mediators of treatment outcome. We do not know how children intuitively conceptualize obsessive-compulsive disorder (OCD), nor do we know the relative impact of biomedical or cognitive behavioural conceptual explanations, yet both are being widely used in psychoeducation for children with OCD. This study identified children's naive concepts of OCD, and the comparative impact of biomedical versus cognitive behavioural psychoeducation on perceived prognosis. A within- and between-subjects experimental design was used. After watching a video of a young person describing their OCD, 202 children completed a questionnaire examining their concepts of the condition. They repeated the questionnaire following a second equivalent video, this time preceded by either biomedical or cognitive behavioural psychoeducation. Participants' naive concepts of OCD reflected predominant models of OCD in healthcare. Even at the minimal dose of psychoeducation, participants' conceptualizations of OCD changed. Prior exposure to OCD resulted in a stronger alignment with the biomedical model. Exposure to biomedical psychoeducation resulted in participants predicting a slower recovery with less chance of complete remission. Psychoeducation for childhood OCD is impactful. Despite its wide use by clinicians and mental health services, biomedical psychoeducation appears to have deleterious effects. Children's concepts of OCD merit attention but caution should be applied in how they are targeted.

Nicotine cravings are a key target of smoking cessation interventions. Cravings demonstrate circadian variation during abstinence, often peaking during the morning and evening hours. Although some research has also shown diurnal variation in the efficacy of nicotine replacement medications, little research has examined how brief psychosocial interventions affect temporal patterns of craving during abstinence. The present study examined the impact of two brief psycho-education interventions on circadian variations in cravings during a 24-h period. 176 adult smokers interested in quitting participated in two lab sessions. During the first session, participants received (a) mindfulness psycho-education that encouraged acceptance of cravings as a normal, tolerable part of quitting that people should not expect to perfectly control, (b) standard cessation psycho-education, or (c) no psycho-education. Half the sample initiated a cessation attempt the following day. Dependent variables were assessed using ecological momentary assessment (24-h of monitoring, immediately after first lab session) and questionnaires four days later. Partially consistent with hypotheses, both forms of psycho-education were associated with differential diurnal variation in cravings during cessation. Relative to those receiving no psycho-education, standard smoking cessation psycho-education decreased morning cravings. Psycho-education encouraging acceptance of cravings was associated with lower craving in both the morning and evening, albeit only among successfully abstinent smokers. Results demonstrate that brief non-pharmacological interventions can affect circadian craving patterns during smoking cessation. Further investigation of mechanisms of change and of the impact of psycho-education on cessation outcomes is warranted. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

This study evaluated the effectiveness of a telephone-delivered psychoeducational intervention for family caregivers of PWD in alleviating caregiver burden and enhancing caregiving self-efficacy. Subjects and methods: In a single-blinded randomized controlled trial, 38 family caregivers of PWD were randomly allocated into an intervention group or a control group. The intervention group received psychoeducation from a registered social worker over the phone for 12 sessions. Caregivers in the control group were given a DVD containing educational information about dementia caregiving. Outcomes of the intervention were measured by the Chinese versions of the Zarit Burden Interview and the Revised Scale for Caregiving Self-efficacy. Mann–Whitney U tests were used to compare the differences between the intervention and control groups. Results: The level of burden of caregivers in the intervention group reduced significantly compared with caregivers in the control group. Caregivers in the intervention group also reported significantly more gain in self-efficacy in obtaining respite than the control group. Conclusion: A structured telephone intervention can benefit dementia caregivers in terms of self-efficacy and caregiving burden. The limitations of the research and recommendations for intervention are discussed. Keywords: telephone intervention, psychoeducation, dementia caregivers

Psychoeducation (PE) is defined as an intervention with systematic, structured, and didactic knowledge transfer for an illness and its treatment, integrating emotional and motivational aspects to enable patients to cope with the illness and to improve its treatment adherence and efficacy. PE is considered an important component of treatment in both medical and psychiatric disorders, especially for mental health disorders associated with lack of insight, such as alcohol and substance use disorders (ASUDs). New advancements in neuroscience have shed light on how various aspects of ASUDs may relate to neural processes. However, the actual impact of neuroscience in the real-life clinical practice of addiction medicine is minimal. In this chapter, we provide a perspective on how PE in addiction medicine can be informed by neuroscience in two dimensions: content (knowledge we transfer in PE) and structure (methods we use to deliver PE). The content of conventional PE targets knowledge about etiology of illness, treatment process, adverse effects of prescribed medications, coping strategies, family education, and life skill training. Adding neuroscience evidence to the content of PE could be helpful in communicating not only the impact of drug use but also the beneficial impact of various treatments (i.e., on brain function), thus enhancing motivation for compliance and further destigmatizing their symptoms. PE can also be optimized in its "structure" by implicitly and explicitly engaging different neurocognitive processes, including salience/attention, memory, and self-awareness. There are many interactions between these two dimensions, structure and content, in the delivery of neuroscience-informed psychoeducation (NIPE). We explore these interactions in the development of a cartoon-based NIPE to promote brain recovery during addiction treatment as a part of the brain awareness for addiction recovery initiative. © 2017 Elsevier B.V.

Although sexual health is a common concern for oncology patients, no practical guidelines to sexual intervention exist, perhaps because of a lack of systematic reviews or meta-analyses. The objectives of this study were to determine the effect size for psychoeducational intervention focused on sexuality and to compare effect sizes according to intervention outcomes and characteristic. We explored quantitative evidence for the effects of sexual intervention for cancer patients or partners by using the electronic databases. Among them, we considered 15 eligible articles. The meta-analysis provided 133 effect sizes from 15 primary studies. The analysis revealed significant improvements after intervention, with a random-effects standardized mean difference of 0.75. Psychoeducational interventions focused on sexuality after cancer diagnosis were effective for compliance (2.40), cognitive aspect (1.29), and psychological aspect (0.83). Individual-based interventions (0.85) were more effective in improving outcomes than group approach and group combined with individual intervention. With regard to intervention providers, registered nurse only (2.22) and team approach including the registered nurse (2.38) had the highest effect size. Face-to-face intervention combined with telephone or the Internet (1.04) demonstrated a higher effect size than face-to-face (0.62) and telephone (0.58) independently. We conducted an analysis of data from various subgroups of preexisting studies, obtained an overall estimate of the effectiveness of the intervention, and compared its effectiveness across variables that affect intervention outcomes. These results provide empirical data for evidence-based practice and inform the development of useful intervention programs through a comprehensive review and meta-analysis of the results.

Full Text Available Abstract Background Given the high prevalence and burden associated with depression and anxiety disorders and the existence of treatment barriers, there is a clear need for brief, inexpensive and effective interventions such as passive psychoeducational interventions. There are no published meta-analyses of the effectiveness of passive psychoeducation in reducing symptoms of depression, anxiety or psychological distress. Methods Cochrane, PsycInfo and PubMed databases were searched in September 2008. Additional materials were obtained from reference lists. Papers describing passive psychoeducational interventions for depression, anxiety and psychological distress were included if the research design was a randomized controlled trial and incorporated an attention placebo, no intervention or waitlist comparison group. Results In total, 9010 abstracts were identified. Of these, five papers which described four research studies targeting passive psychoeducation for depression and psychological distress met the inclusion criteria. The pooled standardized-effect size (four studies, four comparisons for reduced symptoms of depression and psychological distress at post-intervention was d = 0.20 (95% confidence interval: 0.01-0.40; Z = 2.04; P = 0.04; the number needed to treat: 9. Heterogeneity was not significant among the studies (I2 = 32.77, Q:4.46; P = 0.22. Conclusions Although it is commonly believed that psychoeducation interventions are ineffective, this meta-analysis revealed that brief passive psychoeducational interventions for depression and psychological distress can reduce symptoms. Brief passive psychoeducation interventions are easy to implement, can be applied immediately and are not expensive. They may offer a first-step intervention for those experiencing psychological distress or depression and might serve as an initial intervention in primary care or community models. The findings suggest that the quality of psychoeducation may be

Radiotherapy (RT) has become an important treatment modality in pediatric oncology, but its delivery to young children with cancer is challenging and general anesthesia is often needed. To evaluate whether a psychoeducational intervention might reduce the need for anesthesia, 223 consecutive pediatric cancer patients receiving 4141 RT fractions during 244 RT courses between February 1989 and January 2006 were studied. Whereas in 154 RT courses corresponding with 2580 RT fractions patients received no psychoeducational intervention (group A), 90 RT courses respectively 1561 RT fractions were accomplished by using psychoeducational intervention (group B). This tailored psychoeducational intervention in group B included a play program and interactive support by a trained nurse according to age to get familiar with staff, equipment and procedure of radiotherapy. Group A did not differ significantly from group B in age at RT, gender, diagnosis, localization of RT and positioning during RT. Whereas 33 (21.4%) patients in group A got anesthesia, only 8 (8.9%) patients in group B needed anesthesia. The median age of cooperating patients without anesthesia decreased from 3.2 to 2.7 years. In both uni- and multivariate analyses the psychoeducational intervention significantly and independently reduced the need for anesthesia. We conclude that a specifically tailored psychoeducational intervention is able to reduce the need for anesthesia in children undergoing RT for cancer. This results in lower costs and increased cooperation during RT

We formulate a simple human-pose tracking theory from monocular video based on the fundamental relationship between changes in pose and image motion vectors. We investigate the natural embedding of the low-dimensional body pose space into a high-dimensional space of body configurations that behaves locally in a linear manner. The embedded manifold facilitates the decomposition of the image motion vectors into basis motion vector fields of the tangent space to the manifold. This approach benefits from the style invariance of image motion flow vectors, and experiments to validate the fundamental theory show reasonable accuracy (within 4.9 deg of the ground truth).

In Western societies spiders are among the least liked of all arthropods, eliciting feelings of fear and disgust. The clinical manifestation of this fear - spider phobia - is a common anxiety disorder. In most cases the disorder has an early onset in childhood. The symptoms show a chronic course and can persist into adulthood if not treated. Etiological models emphasize the role of modeling and negative information transmission for the acquisition of the disorder. Even though powerful psychotherapeutic methods exist, referral to treatment is rather uncommon for children. Often spontaneous remission is expected, but that is atypical. The current study developed a psychoeducative program on spiders for elementary school children and evaluated it on a sample of 36 children aged 8 to 10 years. The main goal of this pilot study was to test the feasibility of the program. The study showed a reduction of fear of spiders after psychoeducation in girls and boys with previously high or moderate fear of spiders. The program could become a valuable contribution to the prevention of spider phobia and should be evaluated in future controlled trials.

New technologies have recently been used for monitoring signs and symptoms of mental health illnesses and particularly have been tested to improve the outcomes in bipolar disorders. Web-based psychoeducational programs for bipolar disorders have also been implemented, yet to our knowledge, none of them have integrated both approaches in one single intervention. The aim of this project is to develop and validate a smartphone application to monitor symptoms and signs and empower the self-management of bipolar disorder, offering customized embedded psychoeducation contents, in order to identify early symptoms and prevent relapses and hospitalizations. The project will be carried out in three complementary phases, which will include a feasibility study (first phase), a qualitative study (second phase) and a randomized controlled trial (third phase) comparing the smartphone application (SIMPLe) on top of treatment as usual with treatment as usual alone. During the first phase, feasibility and satisfaction will be assessed with the application usage log data and with an electronic survey. Focus groups will be conducted and technical improvements will be incorporated at the second phase. Finally, at the third phase, survival analysis with multivariate data analysis will be performed and relationships between socio-demographic, clinical variables and assessments scores with relapses in each group will be explored. This project could result in a highly available, user-friendly and not costly monitoring and psychoeducational intervention that could improve the outcome of people suffering from bipolar disorders in a practical and secure way.

The authors tested whether engaging in expansive (vs. contractive) "power poses" before a stressful job interview--preparatory power posing--would enhance performance during the interview. Participants adopted high-power (i.e., expansive, open) poses or low-power (i.e., contractive, closed) poses, and then prepared and delivered a speech to 2 evaluators as part of a mock job interview. All interview speeches were videotaped and coded for overall performance and hireability and for 2 potential mediators: verbal content (e.g., structure, content) and nonverbal presence (e.g., captivating, enthusiastic). As predicted, those who prepared for the job interview with high- (vs. low-) power poses performed better and were more likely to be chosen for hire; this relation was mediated by nonverbal presence, but not by verbal content. Although previous research has focused on how a nonverbal behavior that is enacted during interactions and observed by perceivers affects how those perceivers evaluate and respond to the actor, this experiment focused on how a nonverbal behavior that is enacted before the interaction and unobserved by perceivers affects the actor's performance, which, in turn, affects how perceivers evaluate and respond to the actor. This experiment reveals a theoretically novel and practically informative result that demonstrates the causal relation between preparatory nonverbal behavior and subsequent performance and outcomes.

This paper describes a genetic algorithm that tackles the pose-estimation problem in computer vision. Our genetic algorithm can find the rotation and translation of an object accurately when the three-dimensional structure of the object is given. In our implementation, each chromosome encodes both the pose and the indexes to the selected point features of the object. Instead of only searching for the pose as in the existing work, our algorithm, at the same time, searches for a set containing the most reliable feature points in the process. This mismatch filtering strategy successfully makes the algorithm more robust under the presence of point mismatches and outliers in the images. Our algorithm has been tested with both synthetic and real data with good results. The accuracy of the recovered pose is compared to the existing algorithms. Our approach outperformed the Lowe's method and the other two genetic algorithms under the presence of point mismatches and outliers. In addition, it has been used to estimate the pose of a real object. It is shown that the proposed method is applicable to augmented reality applications.

The aim of this randomized controlled trial was to compare the effectiveness of psychoeducation versus cognitive behavioral therapy (CBT) in the management of depression among renal dialysis patients. A sample of 130 dialysis patients participated in the study and they were assigned at random to one of two therapies: psychoeducation (N = 65) or CBT (N = 65). Hamilton depression rating scale was completed by the participants in both groups prior to the therapies and after completion. Both therapies were effective in the management of depression, although psychoeducation was superior. Psychoeducation is recommended over CBT in the management of depression among renal dialysis patients.

The launch of Xbox Kinect has built a very successful computer vision product and made a big impact on the gaming industry. This sheds lights onto a wide variety of potential applications related to action recognition. The accurate estimation of human poses from the depth image is universally a critical step. However, existing pose estimation systems exhibit failures when facing severe occlusion. In this paper, we propose an exemplar-based method to learn to correct the initially estimated poses. We learn an inhomogeneous systematic bias by leveraging the exemplar information within a specific human action domain. Furthermore, as an extension, we learn a conditional model by incorporation of pose tags to further increase the accuracy of pose correction. In the experiments, significant improvements on both joint-based skeleton correction and tag prediction are observed over the contemporary approaches, including what is delivered by the current Kinect system. Our experiments for the facial landmark correction also illustrate that our algorithm can improve the accuracy of other detection/estimation systems.
Hawes, Anthony H.; Iftekharuddin, Khan M.
We propose a novel method for analyzing images that exploits the natural lines of a human poses to find areas where self-occlusion could be present. Errors caused by self-occlusion cause several modern human pose estimation methods to mis-identify body parts, which reduces the performance of most action recognition algorithms. Our method is motivated by the observation that, in several cases, occlusion can be reasoned using only boundary lines of limbs. An intelligent edge detection algorithm based on the above principle could be used to augment the silhouette with information useful for pose estimation algorithms and push forward progress on occlusion handling for human action recognition. The algorithm described is applicable to computer vision scenarios involving 2D images and (appropriated flattened) 3D images.

The current study examined the effects of a psychoeducational intervention designed to target thought-action fusion (TAF) on TAF, thought suppression, and responsibility cognitions. 139 undergraduate students (25 male; 114 female) who were relatively high in TAF with respect to their peers served as participants. Immediately following intervention, individuals who had received psychoeducation regarding TAF reported significantly lower morality TAF scores than individuals who had received psychoeducation regarding thoughts in general and individuals in the control group. At the two-week follow-up assessment, the likelihood TAF scores of those who had received psychoeducation regarding TAF were significantly lower than those of the control group. In addition, the group that received psychoeducation regarding TAF was the only group that did not experience a significant increase in thought suppression from baseline to post-intervention, and was also the only group to experience an increase in both frequency of and belief in low-responsibility thoughts from baseline to follow-up. Implications are discussed. (c) 2010 Elsevier Ltd. All rights reserved.

Sufficient information of patients and their relatives about essence of disease, principles of medicamental therapy, is one of major factors influencing on adherence of patients to therapy. Application of psychoeducation programs allows to activate a patient in partnership with a doctor, that assists the increase of compliance. Research aim - to improve quality of remission and readaptation of patients with paranoid schizophrenia by realization of the psychoeducation programs. 45 women in age of 18-60 being on treatment in the Kharkiv regional clinical psychiatric hospital №3, with a diagnosis paranoid schizophrenia were examined. Psychoeducation lessons were conducted in closed groups for 7-8 persons, 2 times per a week, by duration every lesson for 45 minutes. The psychoeducation module consisted of informative block and forming of practical skills. Realization of psychoeducation lesson in this contingent showed the efficiency. Communicative activity became better for all patients as well as their adherence to therapy, that gave possibility promptly expose and warn development of side effects, improve quality and level of social adaptation of patients life.

Written by two international experts in the field, this book is the first unified survey of the advances made in the last 15 years on key non-standard and improperly posed problems for partial differential equations.This reference for mathematicians, scientists, and engineers provides an overview of the methodology typically used to study improperly posed problems. It focuses on structural stability--the continuous dependence of solutions on the initial conditions and the modeling equations--and on problems for which data are only prescribed on part of the boundary.The book addresses continuou
Full Text Available We present three types of polyhedral surfaces, which are continuously flexible and have not only an initial pose, where all faces are coplanar, but pass during their self-motion through another pose with coplanar faces (“flat pose”. These surfaces are examples of so-called rigid origami, since we only admit exact flexions, i.e., each face remains rigid during the motion; only the dihedral angles vary. We analyze the geometry behind Miura-ori and address Kokotsakis’ example of a flexible tessellation with the particular case of a cyclic quadrangle. Finally, we recall Bricard’s octahedra of Type 3 and their relation to strophoids.

The lexicographic order is not representable by a real-valued function, contrary to many other orders or preorders. So, standard tools and results for well-posed minimum problems cannot be used. We prove that under suitable hypotheses it is however possible to guarantee the well-posedness of a lexicographic minimum over a compact or convex set. This result allows us to prove that some game theoretical solution concepts, based on lexicographic order are well-posed: in particular, this is true for the nucleolus.

Bipolar disorder has adverse effects on the lives of the individuals and the people around them and causes disability due to impaired social and occupational functioning, risk of suicide, and frequent relapses. This study was conducted as a two-group pretest-posttest design to determine the effect of psychoeducation on the functioning levels of patients with bipolar disorder. A total of 80 patients were assigned to either the experimental (n = 40) or the control group (n = 40). The data were collected using a questionnaire form, and the Bipolar Disorder Functioning Questionnaire. The experimental group scored significantly higher on the functioning levels (emotional functioning, intellectual functioning, feelings of stigmatization, social withdrawal, household relations, relations with friends, participating in social activities, daily activities and recreational activities, taking initiative and self-sufficiency, and occupation) (p < .05) compared with the control group after psychoeducation. Psychoeducation has become considerably effective in increasing the functioning levels of patients with bipolar disorder.

The reciprocal relationship between the mind and body has been a neglected process for improving the psychosocial care of cancer patients. Emotions form an important link between the mind and body. They play a fundamental role in the cognitive functions of decision-making and symptom control. Recognizing this relationship is important for integrative oncology. We define psychoeducation as the teaching of self-evaluation and self-regulation of the mind-body process. A gap exists between research evidence and implementation into clinical practice. The patients' search for self-empowerment through the pursuit of complementary therapies may be a surrogate for inadequate psychoeducation. Integrative oncology programs should implement psychoeducation that helps patients to improve both emotional and cognitive intelligence, enabling them to better negotiate cancer treatment systems.

Little is known about the effectiveness of a comprehensive psychoeducational intervention on depression, self-esteem, and parenting attitudes/beliefs of at-risk pregnant and parenting adolescents. Adolescents (N = 41) attending either a residential treatment facility (RTF) or a rural alternative school (RAS) participated in a psychoeducational parenting group using Bavolek's Nurturing Program during Phase I. Phase II included health promotion issues, infant massage, and CPR. Using the Parenting Semantic Differential and the AAPI-2, there was significant improvement in parenting attitudes and beliefs. No significant change was found in self-esteem. A comprehensive psychoeducational parenting group can be effective in changing parenting attitudes and beliefs, which suggests an ultimate improvement in health promotion and disease prevention in adolescent women and their children.

In order to meet the aviation's and machinery manufacturing's pose measurement need of high precision, fast speed and wide measurement range, and to resolve the contradiction between measurement range and resolution of vision sensor, this paper proposes an orthogonally splitting imaging pose measurement method. This paper designs and realizes an orthogonally splitting imaging vision sensor and establishes a pose measurement system. The vision sensor consists of one imaging lens, a beam splitter prism, cylindrical lenses and dual linear CCD. Dual linear CCD respectively acquire one dimensional image coordinate data of the target point, and two data can restore the two dimensional image coordinates of the target point. According to the characteristics of imaging system, this paper establishes the nonlinear distortion model to correct distortion. Based on cross ratio invariability, polynomial equation is established and solved by the least square fitting method. After completing distortion correction, this paper establishes the measurement mathematical model of vision sensor, and determines intrinsic parameters to calibrate. An array of feature points for calibration is built by placing a planar target in any different positions for a few times. An terative optimization method is presented to solve the parameters of model. The experimental results show that the field angle is 52 °, the focus distance is 27.40 mm, image resolution is 5185×5117 pixels, displacement measurement error is less than 0.1mm, and rotation angle measurement error is less than 0.15°. The method of orthogonally splitting imaging pose measurement can satisfy the pose measurement requirement of high precision, fast speed and wide measurement range.
Full Text Available Determination of the relative pose of satellites is essential in space rendezvous operations and on-orbit servicing missions. The key problems are the adoption of suitable sensor on board of a chaser and efficient techniques for pose estimation. This paper aims to estimate the pose of a target satellite in close range on the basis of its known model by using point cloud data generated by a flash LIDAR sensor. A novel model based pose estimation method is proposed; it includes a fast and reliable pose initial acquisition method based on global optimal searching by processing the dense point cloud data directly, and a pose tracking method based on Iterative Closest Point algorithm. Also, a simulation system is presented in this paper in order to evaluate the performance of the sensor and generate simulated sensor point cloud data. It also provides truth pose of the test target so that the pose estimation error can be quantified. To investigate the effectiveness of the proposed approach and achievable pose accuracy, numerical simulation experiments are performed; results demonstrate algorithm capability of operating with point cloud directly and large pose variations. Also, a field testing experiment is conducted and results show that the proposed method is effective.

In this work, we present a method for estimating 3-D motion parameters; this method provides an alternative way for 3D head pose estimation from image sequence in the current computer vision literature. This method is robust over extended sequences and large head motions and accurately extracts the orientation angles of head from a single view. Experimental results show that this tracking system works well for development a human-computer interface for people that possess severe motor incapacity

Head pose can be seen as a coarse estimation of gaze direction. In automotive industry, knowledge about gaze direction could optimize Human-Machine Interface (HMI) and Advanced Driver Assistance Systems (ADAS). Pose estimation systems are often based on camera when applications have to be contactless. In this paper, we explore uncooled thermal imagery (8-14μm) for its intrinsic night vision capabilities and for its invariance versus lighting variations. Two methods are implemented and compared, both are aided by a 3D model of the head. The 3D model, mapped with thermal texture, allows to synthesize a base of 2D projected models, differently oriented and labeled in yaw and pitch. The first method is based on keypoints. Keypoints of models are matched with those of the query image. These sets of matchings, aided with the 3D shape of the model, allow to estimate 3D pose. The second method is a global appearance approach. Among all 2D models of the base, algorithm searches the one which is the closest to the query image thanks to a weighted least squares difference.

This study aims at describing the creativity of elementary school students with different cognitive styles in mathematical problem-posing. The posed problems were assessed based on three components of creativity, namely fluency, flexibility, and novelty. The free-type problem posing was used in this study. This study is a descriptive research with qualitative approach. Data collections were conducted through written task and task-based interviews. The subjects were two elementary students. One of them is Field Dependent (FD) and the other is Field Independent (FI) which were measured by GEFT (Group Embedded Figures Test). Further, the data were analyzed based on creativity components. The results show thatFD student’s posed problems have fulfilled the two components of creativity namely fluency, in which the subject posed at least 3 mathematical problems, and flexibility, in whichthe subject posed problems with at least 3 different categories/ideas. Meanwhile,FI student’s posed problems have fulfilled all three components of creativity, namely fluency, in which thesubject posed at least 3 mathematical problems, flexibility, in which thesubject posed problems with at least 3 different categories/ideas, and novelty, in which the subject posed problems that are purely the result of her own ideas and different from problems they have known.

The role of emotional security in promoting positive adjustment following exposure to marital conflict has been identified in a large number of empirical investigations, yet to date, no interventions have explicitly addressed the processes that predict child adjustment after marital conflict. The current study evaluated a randomized controlled trial of a family intervention program aimed at promoting constructive marital conflict behaviors thereby increasing adolescent emotional security and adjustment. Families (n = 225) were randomized into 1 of 4 conditions: Parent-Adolescent (n = 75), Parent-Only (n = 75), Self-Study (n = 38) and No Treatment (n = 37). Multi-informant and multi-method assessments were conducted at baseline, post-treatment and 6-month follow-up. Effects of treatment on destructive and constructive conflict behaviors were evaluated using multilevel models where observations were nested within individuals over time. Process models assessing the impact of constructive and destructive conflict behaviors on emotional insecurity and adolescent adjustment were evaluated using path modeling. Results indicated that the treatment was effective in increasing constructive conflict behaviors (d = 0.89) and decreasing destructive conflict behaviors (d = -0.30). For the Parent-Only Group, post-test constructive conflict behaviors directly predicted lower levels of adolescent externalizing behaviors at 6-month follow-up. Post-test constructive conflict skills also indirectly affected adolescent internalizing behaviors through adolescent emotional security. These findings support the use of a brief psychoeducational intervention in improving post-treatment conflict and emotional security about interparental relationships.

Pose estimation of people have had great progress in recent years but so far research has dealt with single persons. In this paper we address some of the challenges that arise when doing pose estimation of interacting people. We build on the pictorial structures framework and make important...... contributions by combining color-based appearance and edge information using a measure of the local quality of the appearance feature. In this way we not only combine the two types of features but dynamically find the optimal weighting of them. We further enable the method to handle occlusions by searching...... a foreground mask for possible occluded body parts and then applying extra strong kinematic constraints to find the true occluded body parts. The effect of applying our two contributions are show through both qualitative and quantitative tests and show a clear improvement on the ability to correctly localize...

The two main aims of the course were: that the participants learn basic computer skills, and that the participants learn to cope better with social anxiety. Computer skills were taught by a qualified teacher. Psychoeducation and cognitive therapy skills, including topics such as anxiety coping, self-accept, and self-regulation, were taught by a clinical psychologist. Thirteen of 16 participants completed the course, which lasted 11 weeks. A qualitative analysis was performed, drawing on observations during the course and on interviews with the participants. The participants were positive about the integration of psychoeducation sessions in the computer course, and described positive outcomes for both elements, including improved computer skills, improved self-esteem, and reduced social anxiety. Most participants were motivated to undertake further occupational rehabilitation after the course.Keywords: cognitive therapy, information technology, occupational rehabilitation, psychoeducation, self-help, social anxiety

There is considerable evidence that family psycho-education combined with pharmacological intervention for patients with schizophrenia increases family understanding of the illness, reduces the familial burden of care, and improves patient outcomes. However, no studies have determined whether the burden of care is greater for those families with more than one ill member (multiplex) than for families with a single-affected individual (simplex), and whether psycho-educational programs should be adapted to meet the specific needs of multiplex families. This study was conducted at a tertiary care postgraduate teaching hospital in New Delhi, India. Caregivers in simplex [n = 50] and multiplex families [n = 30] were compared with regard to levels of burden, coping, and the impact of psycho-education on family functioning. All the caregiver participants attended eight bimonthly, psycho-educational intervention sessions. They were assessed on the Burden Assessment Schedule (BAS) and the Coping Check List (CCL) before and after psycho-education. Caregivers from the multiplex families reported significantly more burden on two domains of the BAS, but there were no significant differences between the groups with regard to coping on the CCL. Following psycho-education, significant improvement occurred in the majority of domains of the BAS and the CCL; the effect sizes varied by domain and family type. Multiplex families face a greater burden of care compared with simplex families. Currently, available psycho-education programs are moderately effective for such families.

Family and patient psychoeducation have demonstrated significant improvement in clinical and social outcomes for patients suffering from severe mental disorders and their families. However, these evidence-based practices are not widely implemented at service delivery level and into routine clinical practice, especially in less developed countries. The aim of this article is to report the processes of development and implementation of a psychoeducational service for patients with severe mental illnesses and their families in Iran. The program was developed at Roozbeh Hospital in Tehran, Iran. A group of clinicians worked on the development phase of the program and drafting the manuals. Then, a series of workshops and supervision sessions were held to train group leaders for implementation of the group psychoeducation for patients and families. In the pilot phase, the services were delivered to two groups of patients and families, and then the manual was revised based on the feedback from group leaders and participants. The program consisted of eight 90-minute weekly patient group sessions and 6 weekly multiple family group sessions. Two manuals for patient education (schizophrenia and bipolar disorder) were developed. Several information sheets were developed and distributed during different sessions of family and patient psychoeducation related to the content of each session. Despite providing the hospital clinicians with the information regarding these new services, less than 10% of the admitted patients were referred by their clinicians. Feasibility and sustainability of the program are affected by a number of factors. Low referral rate of clinicians, limited resources of the hospital, issues related to stigma and logistic issues are barriers in implementation of these services. Administrators' and clinicians' understanding of the importance of patient and family psychoeducation seems to be crucial in sustainability of such programs in routine service delivery.

The Compact Lightweight Surgery Robot from the University of Hawaii includes two teleoperated instruments and one endoscope manipulator which act in accord to perform assisted interventional medicine. The relative positions and orientations of the robotic instruments and endoscope must be known to the teleoperation system so that the directions of the instrument motions can be controlled to correspond closely to the directions of the motions of the master manipulators, as seen by the the endoscope and displayed to the surgeon. If the manipulator bases are mounted in known locations and all manipulator joint variables are known, then the necessary coordinate transformations between the master and slave manipulators can be easily computed. The versatility and ease of use of the system can be increased, however, by allowing the endoscope or instrument manipulator bases to be moved to arbitrary positions and orientations without reinitializing each manipulator or remeasuring their relative positions. The aim of this work is to find the pose of the instrument end effectors using the video image from the endoscope camera. The P3P pose estimation algorithm is used with a Levenberg-Marquardt optimization to ensure convergence. The correct transformations between the master and slave coordinate frames can then be calculated and updated when the bases of the endoscope or instrument manipulators are moved to new, unknown, positions at any time before or during surgical procedures.

To evaluate the applicability of shape similarity in docking-based pose selection and virtual screening, we participated in the CSARdock2014 benchmark exercise for identifying the correct docking pose of inhibitors targeting factor XA, spleen tyrosine kinase, and tRNA methyltransferase. This exercise provides a valuable opportunity for researchers to test their docking programs, methods, and protocols in a blind testing environment. In the CSARdock2014 benchmark exercise, we have implemented an approach that uses ligand 3D shape similarity to facilitate docking-based pose selection and virtual screening. We showed here that ligand 3D shape similarity between bound poses could be used to identify the native-like pose from an ensemble of docking-generated poses. Our method correctly identified the native pose as the top-ranking pose for 73% of test cases in a blind testing environment. Moreover, the pose selection results also revealed an excellent correlation between ligand 3D shape similarity scores and RMSD to X-ray crystal structure ligand. In the virtual screening exercise, the average RMSD for our pose prediction was found to be 1.02 Å, and it was one of the top performances achieved in CSARdock2014 benchmark exercise. Furthermore, the inclusion of shape similarity improved virtual screening performance of docking-based scoring and ranking. The coefficient of determination (r(2)) between experimental activities and docking scores for 276 spleen tyrosine kinase inhibitors was found to be 0.365 but reached 0.614 when the ligand 3D shape similarity was included.
Full Text Available This paper proposes a novel vision and inertial fusion algorithm S2fM (Simplified Structure from Motion for camera relative pose estimation. Different from current existing algorithms, our algorithm estimates rotation parameter and translation parameter separately. S2fM employs gyroscopes to estimate camera rotation parameter, which is later fused with the image data to estimate camera translation parameter. Our contributions are in two aspects. (1 Under the circumstance that no inertial sensor can estimate accurately enough translation parameter, we propose a translation estimation algorithm by fusing gyroscope sensor and image data. (2 Our S2fM algorithm is efficient and suitable for smart devices. Experimental results validate efficiency of the proposed S2fM algorithm.

Interpretation & conclusions: Treatment with antipsychotics and psychoeducation can favourably influence the course of schizophrenia and reduce disability in a substantial proportion of patients. Structured psychosocial interventions may be indicated in the significant minority who show suboptimal outcome with this strategy.
There is evidence that psycho-education courses for caregivers of individuals with schizophrenia improve the short-term outcome of the condition. However, most of the outcome studies are limited to two-year follow-up.

Two quasi-experimental pilot studies examined eating pathology, eating self-efficacy, shame, guilt, and pride in adults with chronic illness before and after participating in brief cognitive-behavioral psychoeducational groups addressing eating concerns. In Study 1, 60 adults completed assessments before and after a series of two groups; in Study 2, 21 adults also completed an assessment five weeks prior to the first group to identify time-related changes in symptoms. Study 1 participants improved across domains, whereas Study 2 analyses also examining time-related changes showed improvements in eating self-efficacy, shame, guilt, and pride, but not in eating pathology. Psychoeducational groups may help improve symptoms including eating pathology, eating self-efficacy, shame, guilt, and pride among chronically-ill adults with eating concerns. 2009 Elsevier Ltd.

Posiva has conducted in the ONKALO rock characterisation facility during 2010 - 2011 an in situ experiment named POSE (Posiva's Olkiluoto Spalling Experiment). The POSE experiment had three objectives: to establish the in situ spalling/damage strength of Olkiluoto migmatitic gneiss, to establish the state of in situ stress at the -345 m depth level, and to act as a Prediction-Outcome (P-O) exercise. The POSE experiment consisted of drilling with full-face boring machine two near fullscale deposition holes, diameter 1.52 m (compared to 1.75 m for the actual deposition holes), to a depth of 7.2 m, leaving a 0.9 m pillar between the holes. The holes were planned to be located in such way that maximum excavation-induced stresses could act in the pillar and damage could then take place. Boring of the two holes in 2010 was called Phase 1 (Pillar test). This was followed in 2011 by Phase 2 (Pillar heating test) where four heaters with a length of 7.5 m heated the test area to increase the stresses around the experimental holes. In the heating phase the other hole was back-filled with sand. The test was extensively monitored during the execution using temperature monitoring, strain gauge monitoring, video monitoring, microseismic monitoring and pressure monitoring. In addition, the holes were after the test measured using ground penetration radar (GPR) and 3D photogrammetry for detailed modelling. The outcomes from the test showed that no damage, except for three opened/sheared fractures, was noticed during the boring of the holes (Phase 1). Surface damage was, though, induced by heating (Phase 2). The damage was well localized around the holes and controlled by the foliation (mica rich layers) and rock type contacts which were known to be relatively weak. Surface type failures were not observed in the gneiss, but it was noticed in limited areas in the pegmatite-granite. The depths of the damaged areas due to heating were less than 100 mm.

To analyze differences in tooth display, lip-line height, and smile width between the posed smiling record, traditionally produced for orthodontic diagnosis, and the spontaneous (Duchenne) smile of joy. The faces of 122 male participants were each filmed during spontaneous and posed smiling. Spontaneous smiles were elicited through the participants watching a comical movie. Maxillary and mandibular lip-line heights, tooth display, and smile width were measured using a digital videographic method for smile analysis. Paired sample t-tests were used to compare measurements of posed and spontaneous smiling. Maxillary lip-line heights during spontaneous smiling were significantly higher than during posed smiling. Compared to spontaneous smiling, tooth display in the (pre)molar area during posed smiling decreased by up to 30%, along with a significant reduction of smile width. During posed smiling, also mandibular lip-line heights changed and the teeth were more covered by the lower lip than during spontaneous smiling. Reduced lip-line heights, tooth display, and smile width on a posed smiling record can have implications for the diagnostics of lip-line height, smile arc, buccal corridors, and plane of occlusion. Spontaneous smiling records next to posed smiling records are therefore recommended for diagnostic purposes. Because of the dynamic nature of spontaneous smiling, it is proposed to switch to dynamic video recording of the smile.

Antisocial personality disorder often co-exists with drug and alcohol use disorders. This trial examined the effectiveness of offering psycho-education for antisocial personality disorder in community substance use disorder treatment centers in Denmark. A total of 176 patients were randomly allocated to treatment as usual (TAU, n = 80) or TAU plus a psycho-educative program, Impulsive Lifestyle Counselling (ILC, n = 96) delivered by site clinicians (n = 39). Using follow-up interviews 3 and 9 months after randomization, we examined changes in drug and alcohol use (Addiction Severity Index Composite Scores), percent days abstinent (PDA) within last month, and aggression as measured with the Buss-Perry Aggression Questionnaire-Short Form and the Self-Report of Aggression and Social Behavior Measure. Overall engagement in psychological interventions was modest: 71 (76 %) of participants randomized to psycho-education attended at least one counselling session, and 21 (23 %) attended all six sessions. The Median number of sessions was 2. All patients reduced drug and alcohol problems at 9 months with small within-group effect sizes. Intention-to-treat analyses indicated significant differences between ILC and TAU in mean drugs composite score (p = .018) and in PDA (p = .041) at 3 months. Aggression declined in both groups, but no differences between ILC and TAU were observed in terms of alcohol problems or aggression at any follow-up. Moderate short-term improvements in substance use were associated with randomization to Impulsive Lifestyle Counselling. The findings support the usefulness of providing psycho-education to outpatients with antisocial personality disorder. ISRCTN registry, ISRCTN67266318 , 17/7/2012.

Full Text Available Abstract Background Non-didactically delivered curriculum based group psychoeducation has been shown to be more effective than both group support in a specialist mood disorder centre in Spain (with effects lasting up to five years, and treatment as usual in Australia. It is unclear whether the specific content and form of group psychoeducation is effective or the chance to meet and work collaboratively with other peers. The main objective of this trial is to determine whether curriculum based group psychoeducation is more clinically and cost effective than unstructured peer group support. Methods/design Single blind two centre cluster randomised controlled trial of 21 sessions group psychoeducation versus 21 sessions group peer support in adults with bipolar 1 or 2 disorder, not in current episode but relapsed in the previous two years. Individual randomisation is to either group at each site. The groups are carefully matched for the number and type of therapists, length and frequency of the interventions and overall aim of the groups but differ in content and style of delivery. The primary outcome is time to next bipolar episode with measures of the therapeutic process, barriers and drivers to the effective delivery of the interventions and economic analysis. Follow up is for 96 weeks after randomisation. Discussion The trial has features of both an efficacy and an effectiveness trial design. For generalisability in England it is set in routine public mental health practice with a high degree of expert patient involvement.

Although psychoeducation has been found effective for improving the life functioning of patients with schizophrenia in high income countries, there have been relatively few studies of schizophrenia psychoeducation adapted for low and middle-income countries (LMIC), particularly in Southeast Asia. The present study assessed effects of the Family Schizophrenia Psychoeducation Program (FSPP) among Vietnamese patients and their families on the patients' (1) quality of life and (2) medication non-compliance, and the family and patients' (3) stigma towards schizophrenia, and (4) consumer satisfaction. This intervention study involved 59 patients, and their families, from the Da Nang Psychiatric Hospital, randomly assigned to treatment (n=30) or control (n=29) conditions. Control subjects received services as usual (antipsychotic medication); treatment group subjects received the FSPP as well. Blind-rater assessments were conducted at T1 immediately after project enrollment (prior to participating in the FSPP) and at T2 six months later. There were significant treatment effects on: (1) quality of life, (2) stigma, (3) medication compliance, and (4) consumer satisfaction, with all effects favoring the treatment group. Effect sizes were moderate to large. This psychoeducation program appears to reduce stigma, improve quality of life and medication compliance, and increase consumer satisfaction of Vietnamese patients with schizophrenia and their families, beyond the effects of antipsychotic medication. It involves relatively little cost, and it may be useful for it or equivalent programs to be implemented in other hospitals in Viet Nam, and potentially other low-income Asian countries to improve the lives of patients with schizophrenia.

Intervention with at-risk families has changed greatly over recent decades. Thus, intervention based on welfare and deficit theory has given way to preventive intervention that seeks to strengthen and preserve families. Within the framework of this approach, there are psycho-educational programs for parents, the main characteristics of which are presented in this paper. An example of this kind of preventive intervention for parents is the family program coordinated by the Seville Cit...

Depression is the world's fourth most prevalent health problem which is associated with substantial mortality, direct medical cost, diminished life quality, and significant physical and psychosocial impairment. This study aimed to investigate the effect of psycho-educational intervention on the life quality of major depressive patients. Sixty patients who were willing and had met the required criteria for participation were selected from hospitals in Shiraz city, Iran. So 30 of the patients were assigned to the experimental group and 30 others to the control group. For data collection, a two part questionnaire was developed, the first part consists of 13 items related to general characteristics and the second part with 36 items on life quality were used. The experimental group was divided into five subgroups of 6 patients. For each group, six intervention sessions were scheduled. The control group did not receive the intervention. The questionnaires were completed for all subjects in the experimental and control groups before and 1 month after the end of psycho-educational intervention. Tabulated data were analyzed using chi-square, independent and pair T-test. The results of the study indicated that psycho-educational intervention in comparison with other available treatments proved to be more effective on eight domains of life quality in the experimental group. A significant difference was observed for all the domains (P educational intervention can be used as an auxiliary treatment in improving life quality and decreasing depression in patients suffering from major depressive disorder.

Purpose: Although vaginal dilation is often recommended to minimize or prevent vaginal scarring after pelvic radiotherapy, compliance with this recommendation has historically been very low. Therefore, effective intervention strategies are needed to enhance compliance with vaginal dilation after radiotherapy for gynecologic cancer. Methods and Materials: This study was a randomized controlled clinical trial of a psychoeducational intervention specifically designed to increase compliance with vaginal dilation. The information-motivation-behavioral skills model of enhancing compliance with behavioral change was the basis for the intervention design. Forty-two sexually active women, 21 to 65 years of age, diagnosed with Stages Ic-III cervical or endometrial cancer, who received pelvic radiotherapy, were randomized to either the experimental psychoeducational group or the information-only control group. Assessment via questionnaire occurred before treatment and at 6-week, 6-month, 12-month, 18-month, and 24-month follow-up. Assessment via interview also occurred at 6-month, 12-month, 18-month, and 24-month follow-up. Results: The psychoeducational intervention was successful in increasing compliance with vaginal dilation. Conclusions: This study is the first randomized controlled study to demonstrate the effectiveness of an intervention in increasing compliance with the use of vaginal dilators

Benzodiazepines should be prescribed on a short-term basis, but a significant proportion of patients (%) use them for more than 6 months, constituting a serious public health issue. Indeed, few strategies are effective in helping patients to discontinue long-term benzodiazepine treatments. The aim of this study was to assess the feasibility and the impact of a program including cognitive behavioural therapy, psychoeducation, and balneotherapy in a spa resort to facilitate long-term discontinuation of benzodiazepines. We conducted a prospective multicentre cohort study. Patients with long-term benzodiazepine use were recruited with the aim of anxiolytic withdrawal by means of a psychoeducational program and daily balneotherapy during 3 weeks. The primary efficacy outcome measure was benzodiazepine use 6 months after the program, compared to use at baseline. A total of 70 subjects were enrolled. At 6 months, overall benzodiazepine intake had decreased by 75.3%, with 41.4% of patients completely stopping benzodiazepine use. The results also suggest a significantly greater improvement in anxiety and depression symptoms among patients who discontinued benzodiazepines compared to patients who only reduced their use. Our findings suggest that balneotherapy in association with a psychoeducative program is efficient in subjects with benzodiazepine addiction. PMID:27956923

Full Text Available Industrial robots are expected to undertake ever more advanced tasks in the modern manufacturing industry, such as intelligent grasping, in which robots should be capable of recognizing the position and orientation of a part before grasping it. In this paper, a monocular-based 6-degree of freedom (DOF pose estimation technology to enable robots to grasp large-size parts at informal poses is proposed. A camera was mounted on the robot end-flange and oriented to measure several featured points on the part before the robot moved to grasp it. In order to estimate the part pose, a nonlinear optimization model based on the camera object space collinearity error in different poses is established, and the initial iteration value is estimated with the differential transformation. Measuring poses of the camera are optimized based on uncertainty analysis. Also, the principle of the robotic intelligent grasping system was developed, with which the robot could adjust its pose to grasp the part. In experimental tests, the part poses estimated with the method described in this paper were compared with those produced by a laser tracker, and results show the RMS angle and position error are about 0.0228° and 0.4603 mm. Robotic intelligent grasping tests were also successfully performed in the experiments.

Relapses and, subsequently, readmissions are common in patients with schizophrenia. Psychoeducation has been shown to reduce the number and duration of readmissions. Yet, only little more than 20% of psychiatric patients in German speaking countries receive psychoeducation. Among other reasons, costs may be considered too high by hospitals. The objective of the present study was to test the feasibility of a new cost-efficient approach in the psychoeducation of patients with schizophrenia. In this study, films were used to impart knowledge about the illness to inpatients. A total of 113 participants were initially included in the study, eleven of which were not included in the final analyses. Six films about the symptoms, diagnosis, causes, warning signs, treatment of schizophrenia and about the influence of family members and friends were shown in a group setting in the presence of nursing staff. All films combined facts, expert opinions, and personal experiences of peers. As the main outcome criterion of this feasibility pilot study, we measured the effects on knowledge. Secondary outcome measures included compliance, insight into illness, side effects, and quality of life. Data were collected directly after the intervention and about half a year afterwards. The number and the duration of readmissions to the hospital were recorded and compared to the number and duration of prior admissions. Patients were also asked to state their subjective opinion about the films. Main data analyses were done using paired t-tests and Wilcoxon signed-rank tests. Secondary analyses also involved ANOVAs and ANCOVAs. One hundred and two inpatients were included in the data analyses. Showing the films in the tested setting was shown to be feasible. Knowledge about schizophrenia (p < .001), compliance (ps < .01), insight into illness (p < .01), and quality of life (p < .001) all increased significantly after patients had watched the films and remained stable for at

Full Text Available A six-cable driven parallel manipulator and an A-B rotator in the feed support system of the Five-hundred-meter Aperture Spherical radio Telescope (FAST are adopted for realizing the position and pose of nine feeds. The six-cable driven parallel manipulator is a flexible mechanism, which may not be stably controlled due to a small cable tension. The A-B rotator is a rigid mechanism, and its stability and accuracy can be improved by small pose angle. Based on the different characteristics, a pose planning function is presented. The optimization target of the pose planning function is to get the smallest pose angle of the A-B rotator, and the constraint condition can reflect the controllability of the six-cable driven parallel manipulator. Then, the pose planning realization process of the feed support system is proposed. Based on the pose planning method, optimized pose angles of the feed support system for the nine feeds are obtained, which suggests that the pose angle of the six-cable driven parallel manipulator changes from 0° to 14° and the pose angle of the A-B rotator changes from 0° to 26.4°.
Full Text Available Power posing, the adoption of open and powerful postures, has effects that parallel those of actual social power. This study explored the social evaluation of adopting powerful versus powerless body postures in men and women regarding perceived warmth, competence, and the likelihood of eliciting admiration, envy, pity, and contempt. Previous findings suggest that the display of power by women may have side effects due to gender stereotyping, namely reduced warmth ratings and negative emotional reactions. An experiment (N = 2,473 asked participants to rate pictures of men and women who adopted high-power or low-power body postures. High-power posers were rated higher on competence, admiration, envy, and contempt compared to low-power posers, whereas the opposite was true for pity. There was no impact of power posing on perceived warmth. Contrary to expectations, the poser’s gender did not moderate any of the effects. These findings suggest that nonverbal displays of power do influence fundamental dimensions of social perception and their accompanying emotional reactions but result in comparably positive and negative evaluations for both genders.

Depression is common in adolescence and leads to distress and impairment in individuals, families and carers. Treatment and prevention guidelines highlight the key role of information and evidence-based psychosocial interventions not only for individuals but also for their families and carers. Engaging young people in prevention and early intervention programs is a challenge, and early treatment and prevention of adolescent depression is a major public health concern. There has been growing interest in psychoeducational interventions to provide accurate information about health issues and to enhance and develop self-management skills. However, for adolescents with, or at high risk of depression, there is a lack of engaging Web-based psychoeducation programs that have been developed with user input and in line with research guidelines and targeted at both the individual and their family or carer. There are also few studies published on the process of development of Web-based psychoeducational interventions. The aim of this study was to describe the process underlying the design and development of MoodHwb (HwbHwyliau in Welsh): a Web-based psychoeducation multimedia program for young people with, or at high risk of, depression and their families, carers, friends, and professionals. The initial prototype was informed by (1) a systematic review of psychoeducational interventions for adolescent depression; (2) findings from semistructured interviews and focus groups conducted with adolescents (with depressive symptoms or at high risk), parents or carers, and professionals working with young people; and (3) workshops and discussions with a multimedia company and experts (in clinical, research, and multimedia work).

Head pose estimation has been widely used in the field of artificial intelligence, pattern recognition and intelligent human-computer interaction and so on. Good head pose estimation algorithm should deal with light, noise, identity, shelter and other factors robustly, but so far how to improve the accuracy and robustness of attitude estimation remains a major challenge in the field of computer vision. A method based on deep learning for pose estimation is presented. Deep learning with a strong learning ability, it can extract high-level image features of the input image by through a series of non-linear operation, then classifying the input image using the extracted feature. Such characteristics have greater differences in pose, while they are robust of light, identity, occlusion and other factors. The proposed head pose estimation is evaluated on the CAS-PEAL data set. Experimental results show that this method is effective to improve the accuracy of pose estimation.

Despite the use of maintenance medication, recurrence rates in bipolar affective disorder (BPAD) are high. To date, there are no clinical trials that have investigated the use of psychological interventions in bipolar disorder in Pakistan. The purpose of the study was to assess the feasibility and acceptability of a culturally adapted bipolar psychoeducation programme (CaPE) in Pakistan. Thirty-four euthymic bipolar I and II outpatients were randomized to either 12 weekly sessions of individual psychoeducation plus Treatment As Usual (Intervention) or Treatment As Usual (TAU) (Control). Outcomes were assessed using the Young Mania Rating Scale (YMRS), Beck Depression Inventory (BDI), EuroQoL (EQ-5D), Bipolar Knowledge and Attitudes and Questionnaire (BKAQ), and a self-reported measure of medication adherence (Morisky Medication Adherence Scale-4 items, MMAS-4). Effect sizes were derived from baseline adjusted standardized regression coefficients. Retention in the study was good, 80% of patients in the TAU follow-up assessment and 100% of patients in the CaPE group attended all 12 sessions. Patient satisfaction was higher in the CaPE group relative to control (ES = 1.41). Further, there were large effect sizes shown for CaPE versus TAU for medication adherence (MMAS-4: ES = 0.81), knowledge and attitudes towards bipolar (BKAQ: ES = 0.68), mania (YMRS: ES = 1.18), depression (BDI: ES = 1.17) and quality of life measures (EQ-5D: ES ⇒ 0.88). Culturally adapted psychoeducation intervention is acceptable and feasible, and can be effective in improving mood symptoms and knowledge and attitudes to BPAD when compared with TAU. Larger scale studies are needed to confirm our findings. Clinicaltrials.gov identifier NCT02210390.
Full Text Available Background: Bipolar mood disorder type 1 is one of the mostserious psychiatric disorders. We aimed to assess the efficacyof a short-term family–focused treatment for patients with bipolarmood disorder type 1 in a one-year follow-up period.Methods: Sixty patients with bipolar mood disorder and acutemania episodes who referred to Ibn-e-Sina Psychiatric Hospitalin Mashhad were recruited. Half of them were randomly assignedto the psycho-education group. Their available adultfamily members received a psycho-educational training sessionbefore the patients' discharge from the hospital. All patients receivedconcurrent appropriate pharmacotherapy and psychotherapy.All the patients were evaluated by a blind home-visit teamevery 3 months for a period of one year. The evaluation includedthe number of psychiatric visits, patients' adherence, relapsestatus, number of re-hospitalizations, and time to relapse.Results: Fifty-seven patients completed the trial. In the experimentalgroup, there were four patients with relapse(13.79% and in the control group nine patients (31.58% hadrelapse of the disorder (P=0.006.

People tend to display the left cheek when posing for a portrait; however, this effect does not appear to generalise to advertising. The amount of body visible in the image and the sex of the poser might also contribute to the posing bias. Portraits also exhibit lateral lighting biases, with most images being lit from the left. This effect might also be present in advertisements. A total of 2801 full-page advertisements were sampled and coded for posing direction, lighting direction, sex of model, and amount of body showing. Images of females showed an overall leftward posing bias, but the biases in males depended on the amount of body visible. Males demonstrated rightward posing biases for head-only images. Overall, images tended to be lit from the top left corner. The two factors of posing and lighting biases appear to influence one another. Leftward-lit images had more leftward poses than rightward, while the opposite occurred for rightward-lit images. Collectively, these results demonstrate that the posing biases in advertisements are dependent on the amount of body showing in the image, and that biases in lighting direction interact with these posing biases.

We aimed to examine baseline predictors of treatment response in bulimic patients. 241 seeking-treatment females with bulimia nervosa completed an exhaustive assessment and were referred to a six-session psychoeducational group. Regression analyses of treatment response were performed. Childhood obesity, lower frequency of eating symptomatology, lower body mass index, older age, and lower family's and patient's concern about the disorder were predictors of poor abstinence. Suicidal ideation, alcohol abuse, higher maximum BMI, higher novelty seeking and lower baseline purging frequency predicted dropouts. Predictors of early symptom changes and dropouts were similar to those identified in longer CBT interventions.
Full Text Available Hospitalization, despite its duration, is likely to result in emotional, social, and academic costs to school-age children and adolescents. Developing adequate psychoeducational activities and assuring inpatients' own class teachers' collaboration, allows for the enhancement of their personal and emotional competences and the maintenance of a connection with school and academic life. These educational programs have been mainly designed for patients with long stays and/or chronic conditions, in the format of Hospital Schools, and typically in pediatric Hospitals. However, the negative effects of hospitalization can be felt in internments of any duration, and children hospitalized in smaller regional hospitals should have access to actions to maintain the connection with their daily life. Thus, this investigation aims to present a psychoeducational intervention program theoretically grounded within the self-regulated learning (SRL framework, implemented along 1 year in a pediatric ward of a regional hospital to all its school-aged inpatients, regardless of the duration of their stay.

All the 798 school-aged inpatients ( M age = 11.7; SD age = 3.71; M hospital stay = 4 days) participated in pedagogical, leisure nature, and SRL activities designed to train transversal skills (e.g., goal-setting). Moreover, inpatients completed assigned study tasks resulting from the linkage between the students' own class teachers and the hospital teacher. The experiences reported by parents/caregivers and class teachers of the inpatients enrolling in the intervention allowed the researchers to reflect on the potential advantages of implementing a psychoeducational intervention to hospitalized children and adolescents that is: individually tailored, focused on leisure playful theoretically grounded activities that allow learning to naturally occur, and designed to facilitate school re

This study was undertaken among Latinos receiving treatment from a community mental health center in New York City. The primary mental health concern was schizophrenia. We conducted three focus groups and present the viewpoints of consumers, family members, and providers. Using qualitative content analysis we identified four predominant categories: (1) the importance of family ties; (2) stigma about mental illness; (3) respect and trust in interpersonal relationships; and (4) facilitators and barriers to implementing Family Psychoeducation. Analysis of transcripts revealed specific subthemes for each category. Implications for imparting culturally sensitive material into mental health services for Latinos are discussed.

To determine if internet-based psychoeducation for borderline personality disorder is effective in reducing symptom severity and improving psychosocial functioning. Eighty women who met DSM-IV criteria for borderline personality disorder were randomly assigned either to the internet-based psychoeducation treatment group (n = 40) or to the internet-based control group with no psychoeducation (n = 40). Recruitment was conducted from July 2013 to March 2015. Subjects participated in 15 assessment periods that were divided into an acute phase (weeks 1-12) and a maintenance phase (months 6, 9, and 12). Main outcomes were assessed using the Zanarini Rating Scale for Borderline Personality Disorder. In the acute phase, women in the treatment group were found to have a significant decline in their scores on all 10 outcomes studied, while women in the control group had a significant decline on 7 of these outcomes. Two between-group differences were found to be significant-those in the treatment group reported a significantly greater decline in their impulsivity (z = -1.98, P = .048) and a significantly greater increase in their psychosocial functioning (z = -1.97, P = .049) than those in the control group. In the maintenance phase, those in the treatment group were found to have a significant decline in their scores on 9 of the 10 outcomes studied, while those in the control group had a significant decline in 3 of these outcomes. In terms of between-group differences, those in the treatment group reported a significantly greater decline in all 5 studied areas of borderline psychopathology: affective symptoms (z = -2.31, P = .021), cognitive symptoms (z = -3.20, P = .001), impulsivity (z = -2.44, P = .015), interpersonal difficulties (z = -2.15, P = .032), and overall borderline personality disorder symptoms (z = -2.11, P = .035). Taken together, these results suggest that internet-based psychoeducation is an effective form of early treatment for reducing the symptom

The D3R 2015 grand drug design challenge provided a set of blinded challenges for evaluating the applicability of our protocols for pose and affinity prediction. In the present study, we report the application of two different strategies for the two D3R protein targets HSP90 and MAP4K4. HSP90 is a well-studied target system with numerous co-crystal structures and SAR data. Furthermore the D3R HSP90 test compounds showed high structural similarity to existing HSP90 inhibitors in BindingDB. Thus, we adopted an integrated docking and scoring approach involving a combination of both pharmacophoric and heavy atom similarity alignments, local minimization and quantitative structure activity relationships modeling, resulting in the reasonable prediction of pose [with the root mean square deviation (RMSD) values of 1.75 Å for mean pose 1, 1.417 Å for the mean best pose and 1.85 Å for the mean all poses] and affinity (ROC AUC = 0.702 at 7.5 pIC50 cut-off and R = 0.45 for 180 compounds). The second protein, MAP4K4, represents a novel system with limited SAR and co-crystal structure data and little structural similarity of the D3R MAP4K4 test compounds to known MAP4K4 ligands. For this system, we implemented an exhaustive pose and affinity prediction protocol involving docking and scoring using the PLANTS software which considers side chain flexibility together with protein-ligand fingerprints analysis assisting in pose prioritization. This protocol through fares poorly in pose prediction (with the RMSD values of 4.346 Å for mean pose 1, 4.69 Å for mean best pose and 4.75 Å for mean all poses) and produced reasonable affinity prediction (AUC = 0.728 at 7.5 pIC50 cut-off and R = 0.67 for 18 compounds, ranked 1st among 80 submissions).

Objective. Hypohidrotic ectodermal dysplasia (HED) is an X-linked hereditary disorder characterized by hypohidrosis, hypotrichosis, and anomalous dentition. Estimates of up to 50% of affected children having intellectual disability are controversial. Method. In a cross-sectional study, 45 youth with HED (77% males, mean age 9.75 years) and 59 matched unaffected controls (70% males, mean age 9.79 years) were administered the Kaufman Brief Intelligence Test and the Kaufman Test of Educational Achievement, and their parents completed standardized neurodevelopmental and behavioral measures, educational, and health-related information regarding their child, as well as standardized and nonstandardized data regarding socioeconomic information for their family. Results. There were no statistically significant differences between the two groups in intelligence quotient composite and educational achievement scores, suggesting absence of learning disability in either group. No gender differences within or between groups were found on any performance measures. Among affected youth, parental education level correlated positively with (1) cognitive vocabulary scores and cognitive composite scores; (2) educational achievement for mathematics, reading, and composite scores. Conclusion. Youth affected with HED and unaffected matched peers have similar profiles on standardized measures of cognition, educational achievement, and adaptive functioning although children with HED may be at increased risk for ADHD.

To examine a psychoeducational intervention's effects on knowledge and attitudes toward antipsychotic medication in clients with schizophrenia and schizoaffective disorders. A one-group pretest-posttest design was employed. A convenience sample (61 psychiatric clients aged 20 or above) was recruited from a Korean mental health center. At baseline, participants had limited knowledge (M = 50.89, range: 27-77, SD = 12.05) of and negative feelings toward antipsychotic medications (M = -.89, range: -8 to 8, SD = 4.27). Both measures significantly improved post-intervention. A psychoeducational intervention improved clients' knowledge of and attitudes toward antipsychotic medications. © 2015 Wiley Periodicals, Inc.

The mobile computing device has many limitations, such as relative small user interface and slow computing speed. Usually, augmented reality requires face pose estimation can be used as a HCI and entertainment tool. As far as the realtime implementation of head pose estimation on relatively resource limited mobile platforms is concerned, it is required to face different constraints while leaving enough face pose estimation accuracy. The proposed face pose estimation method met this objective. Experimental results running on a testing Android mobile device delivered satisfactory performing results in the real-time and accurately.
Full Text Available Analyzing human poses with a Kinect is a promising method to evaluate potentials risks of musculoskeletal disorders at workstations. In ecological situations, complex 3D poses and constraints imposed by the environment make it difficult to obtain reliable kinematic information. Thus, being able to predict the potential accuracy of the measurement for such complex 3D poses and sensor placements is challenging in classical experimental setups. To tackle this problem, we propose a new evaluation method based on a virtual mannequin. In this study, we apply this method to the evaluation of joint positions (shoulder, elbow, and wrist, joint angles (shoulder and elbow, and the corresponding RULA (a popular ergonomics assessment grid upper-limb score for a large set of poses and sensor placements. Thanks to this evaluation method, more than 500,000 configurations have been automatically tested, which would be almost impossible to evaluate with classical protocols. The results show that the kinematic information obtained by the Kinect software is generally accurate enough to fill in ergonomic assessment grids. However inaccuracy strongly increases for some specific poses and sensor positions. Using this evaluation method enabled us to report configurations that could lead to these high inaccuracies. As a supplementary material, we provide a software tool to help designers to evaluate the expected accuracy of this sensor for a set of upper-limb configurations. Results obtained with the virtual mannequin are in accordance with those obtained from a real subject for a limited set of poses and sensor placements.

In this paper, we have developed an algorithm to track the pose of a human face robustly and efficiently. Face pose estimation is very useful in many applications such as building virtual reality systems and creating an alternative input method for the disabled. Firstly, we have modified a face detection toolbox called DLib for the detection of a face in front of a camera. The detected face features are passed to a pose estimation method, known as the four-point algorithm, for pose computation. The theory applied and the technical problems encountered during system development are discussed in the paper. It is demonstrated that the system is able to track the pose of a face in real time using a consumer grade laptop computer.
Full Text Available Many computer vision applications such as augmented reality require head pose estimation. As far as the real-time implementation of head pose estimation on relatively resource limited mobile platforms is concerned, it is required to satisfy real-time constraints while maintaining reasonable head pose estimation accuracy. The introduced head pose estimation approach in this paper is an attempt to meet this objective. The approach consists of the following components: Viola-Jones face detection, color-based face tracking using an online calibration procedure, and head pose estimation using Hu moment features and Fisher linear discriminant. Experimental results running on an actual mobile device are reported exhibiting both the real- time and accuracy aspects of the developed approach.

This paper discussed a features point detection and matching task technique for mobile robots used in wind turbine blade applications. The vision-based scheme used visual information from the robot's surrounding environment to match successive image frames. An improved pose estimation algorithm based on a scale invariant feature transform (SIFT) was developed to consider the characteristics of local images of turbine blades, pose estimation problems, and conditions. The method included a pre-subsampling technique for reducing computation and bidirectional matching for improving precision. A random sample consensus (RANSAC) method was used to estimate the robot's pose. Pose estimation conditions included a wide pose range; the distance between neighbouring blades; and mechanical, electromagnetic, and optical disturbances. An experimental platform was used to demonstrate the validity of the proposed algorithm. 20 refs., 6 figs.

Multimedia interventions are increasingly used to deliver information in order to promote self-care among patients with degenerative conditions. We carried out a realist review of the literature to investigate how the characteristics of multimedia psychoeducational interventions combine with the contexts in which they are introduced to help or hinder their effectiveness in supporting self-care for patients with degenerative conditions. Electronic databases (Medline, Science Direct, PSYCHinfo, EBSCO, and Embase) were searched in order to identify papers containing information on multimedia psychoeducational interventions. Using a realist review approach, we reviewed all relevant studies to identify theories that explained how the interventions work. Ten papers were included in the review. All interventions sought to promote self-care behaviors among participants. We examined the development and content of the multimedia interventions and the impact of patient motivation and of the organizational context of implementation. We judged seven studies to be methodologically weak. All completed studies showed small effects in favor of the intervention. Multimedia interventions may provide high-quality information in an accessible format, with the potential to promote self-care among patients with degenerative conditions, if the patient perceives the information as important and develops confidence about self-care. The evidence base is weak, so that research is needed to investigate effective modes of delivery at different resource levels. We recommend that developers consider how an intervention will reduce uncertainty and increase confidence in self-care, as well as the impact of the context in which it will be employed.

Many patients suffering from psychosis are nonadherent to their medications. Nonadherence can range from treatment refusal to irregular use or partial change in daily medication doses. To investigate whether symptom dimensions, post-discharge care plans and being involved with faith healer affect the adherence to treatment in patients with schizophrenia. A total of 121 patients with schizophrenia were examined 6 weeks post-discharge from the inpatient unit and assessed for full, partial or nonadherence to medication. There was a significant association between family involvement and partial adherence and between community team involvement post-discharge and full adherence to medications. Psycho-education was a predictor for adherence to medications, persecutory delusions and lack of insight predicted partial adherence, while being involved with faith healers predicted nonadherence. Adherence to medications and socio-demographic variables are independent. This study demonstrated that nonadherence or partial adherence to medications is associated with lack of insight and persecutory delusions. Psycho-education could improve the adherence to medication compliances. © The Author(s) 2016.
Full Text Available Abstract Background In a recent exploratory randomised trial we found that a novel, internet-based psychoeducation programme for bipolar disorder (Beating Bipolar was relatively easy to deliver and had a modest effect on psychological quality of life. We sought to explore the experiences of participants with respect to feasibility, acceptability and impact of Beating Bipolar. Methods Participants were invited to take part in a semi-structured interview. Thematic analysis techniques were employed; to explore and describe participants’ experiences, the data were analysed for emerging themes which were identified and coded. Results The programme was feasible to deliver and acceptable to participants where they felt comfortable using a computer. It was found to impact upon insight into illness, health behaviour, personal routines and positive attitudes towards medication. Many participants regarded the programme as likely to be most beneficial for those recently diagnosed. Conclusions An online psychoeducation package for bipolar disorder, such as Beating Bipolar, is feasible and acceptable to patients, has a positive impact on self-management behaviours and may be particularly suited to early intervention. Alternative (non-internet formats should also be made available to patients.
Full Text Available Head pose estimation has been an integral problem in the study of face recognition systems and human-computer interfaces, as part of biometric applications. A fine estimate of the head pose angle is necessary and useful for several face analysis applications. To determine the head pose, face images with varying pose angles can be considered to be lying on a smooth low-dimensional manifold in high-dimensional image feature space. However, when there are face images of multiple individuals with varying pose angles, manifold learning techniques often do not give accurate results. In this work, we propose a framework for a supervised form of manifold learning called Biased Manifold Embedding to obtain improved performance in head pose angle estimation. This framework goes beyond pose estimation, and can be applied to all regression applications. This framework, although formulated for a regression scenario, unifies other supervised approaches to manifold learning that have been proposed so far. Detailed studies of the proposed method are carried out on the FacePix database, which contains 181 face images each of 30 individuals with pose angle variations at a granularity of 1Ã¢ÂˆÂ˜. Since biometric applications in the real world may not contain this level of granularity in training data, an analysis of the methodology is performed on sparsely sampled data to validate its effectiveness. We obtained up to 2Ã¢ÂˆÂ˜ average pose angle estimation error in the results from our experiments, which matched the best results obtained for head pose estimation using related approaches.

Siblings of individuals with first episode psychosis are natural partners to promote service users' recovery and are themselves vulnerable to mental ill health due to the negative impact of psychosis within the family. This study aims to develop and undertake a preliminary evaluation of the efficacy of an online multi-component psychoeducational intervention for siblings of individuals with first episode psychosis. The impetus for the intervention arose from siblings' expressed needs for peer support and information on psychosis, coping and management strategies for common symptoms and ways to promote recovery. The project design draws on the Medical Research Council framework for the design and evaluation of complex interventions. Mixed methods comprising collection of qualitative focus group data, systematic review and expert advisory group consultation are used to develop the theoretical basis for and design of the intervention. This protocol focuses on the modelling and piloting phase which uses a randomised controlled trial with factorial design to test the efficacy of the intervention. Outcome data on participants' mental wellbeing, knowledge, perceived self-efficacy and experiences of caregiving will be assessed at baseline, at end of the intervention (10 weeks later) and at 10 week follow-up. In addition, a post-intervention semi-structured interview with 20% of the participants will explore their experiences and acceptability of the intervention. This multi-component online psychoeducational intervention aims to enhance siblings' knowledge about psychosis and their coping capacity, thus potentially improving their own mental wellbeing and promoting their contribution to service users' recovery. The factorial design randomised controlled trial with a supplementary process evaluation using semi-structured interviews and usage-monitoring will collect preliminary evidence of efficacy, feasibility and acceptability, as well as feedback about the barriers and

This manuscript details a randomized controlled study designed to test the efficacy of power posing (i.e., briefly holding postures associated with dominance and power) as an augmentative strategy for exposure therapy for social anxiety disorder (SAD). Seventy-three individuals diagnosed with SAD were assigned to one of three conditions: power posing, submissive posing, or rest (no posing) prior to participating in an exposure therapy session. Participants were assessed for between-group differences in pre- and post-manipulation salivary hormone levels, within-session subjective experiences of fear, and pre- and 1-week post-treatment SAD severity outcome measures. Though the intervention resulted in decreased SAD symptom severity one week later, analyses revealed no significant between-group differences on any tested variables. Accordingly, this study provides no evidence to suggest that power posing impacts hormone levels or exposure therapy outcomes. Copyright © 2017 Elsevier Ltd. All rights reserved.

Markerless video-based human pose estimation algorithms face a high-dimensional problem that is frequently broken down into several lower-dimensional ones by estimating the pose of each limb separately. However, in order to do so they need to reliably locate the torso, for which they typically rely on time coherence and tracking algorithms. Their losing track usually results in catastrophic failure of the process, requiring human intervention and thus precluding their usage in real-time applications. We propose a very fast rough pose estimation scheme based on global shape descriptors built on 3D Zernike moments. Using an articulated model that we configure in many poses, a large database of descriptor/pose pairs can be computed off-line. Thus, the only steps that must be done on-line are the extraction of the descriptors for each input volume and a search against the database to get the most likely poses. While the result of such process is not a fine pose estimation, it can be useful to help more sophisticated algorithms to regain track or make more educated guesses when creating new particles in particle-filter-based tracking schemes. We have achieved a performance of about ten fps on a single computer using a database of about one million entries.

Many researchers have studied the Writing in Performance Task (WiPT) strategy in learning, but only a few paid attention on its relation to the problem-posing skill in mathematics. The problem-posing skill in mathematics covers problem reformulation, reconstruction, and imitation. The purpose of the present study was to examine the effect of WiPT strategy on students’ mathematical problem-posing skill. The research was conducted at a Public Junior Secondary School in Tangerang Selatan. It used a quasi-experimental method with randomized control group post-test. The samples were 64 students consists of 32 students of the experiment group and 32 students of the control. A cluster random sampling technique was used for sampling. The research data were obtained by testing. The research shows that the problem-posing skill of students taught by WiPT strategy is higher than students taught by a conventional strategy. The research concludes that the WiPT strategy is more effective in enhancing the students’ mathematical problem-posing skill compared to the conventional strategy.

There is considerable evidence that family psycho-education combined with pharmacological intervention for patients with schizophrenia increases family understanding of the illness, reduces the familial burden of care, and improves patient outcomes. However, no studies have determined whether the burden of care is greater for those families with more than one ill member (multiplex) than for families with a single-affected individual (simplex), and whether psycho-educational programs should be adapted to meet the specific needs of multiplex families. This study was conducted at a tertiary care postgraduate teaching hospital in New Delhi, India. Caregivers in simplex [n = 50] and multiplex families [n = 30] were compared with regard to levels of burden, coping, and the impact of psycho-education on family functioning. All the caregiver participants attended eight bimonthly, psycho-educational intervention sessions. They were assessed on the Burden Assessment Schedule (BAS) and the Coping Check List (CCL) before and after psycho-education. Caregivers from the multiplex families reported significantly more burden on two domains of the BAS, but there were no significant differences between the groups with regard to coping on the CCL. Following psycho-education, significant improvement occurred in the majority of domains of the BAS and the CCL; the effect sizes varied by domain and family type. Multiplex families face a greater burden of care compared with simplex families. Currently, available psycho-education programs are moderately effective for such families. PMID:29449743

Methods of measuring a RVD (rendezvous and docking) cooperative object's pose from monocular and binocular images respectively are presented. The methods solve the initial values first and optimize the object pose parameters by bundle adjustment. In the disturbance-rejecting binocular method, chosen measurement system parameters of one camera's exterior parameters are modified simultaneously. The methods need three or more cooperative target points to measure the object's pose accurately. Experimental data show that the methods converge quickly and stably, provide accurate results and do not need accurate initial values. Even when the chosen measurement system parameters are subjected to some amount of disturbance, the binocular method manages to provide fairly accurate results.

Psycho-education is now considered as part of the integrated treatment for bipolar disorder. This study aimed to determine the efficacy of group psycho-education on medication adherence and global functioning of patients with bipolar disorder type I. 45 patients with bipolar disorder type I were allocated one of the three groups of psycho-education plus pharmacotherapy, pharmacotherapy and placebo plus pharmacotherapy. A psycho-educational program was conducted for the psycho-educational group during 9 weekly sessions. Medication adherence and global functioning of all the three groups were evaluated before the intervention, three months and six months after the intervention using Medication Adherence Rating Scale (MARS) and Global Assessment of Functioning (GAF). ANOVA was performed to examine the data. In the first and second assessments, the mean score of medication adherence and gobal functioning for patients in the psycho-educational group was significantly higher than that in the control and placebo groups (P=0.001). Medication adherence score of the psycho-educational group was increased from 6.27(0.88) to 7.92(1.38). while the mean score of the psycho-educational group increased from 56.6 (3.58) to 64.17 (2.12):, the global functioning reduced from 56.27(3.17) to 54.17(5.08) in the control group and from 56.67 (3.58) to 56 (4.36) in the placebo group. Psycho-educational program plus pharmacotherapy was effective in improvement medication adherence and global functioning of bipolar patients.

The detection of pose invariant planar patterns has many practical applications in computer vision and surveillance systems. The recognition of company logos is used in market studies to examine the visibility and frequency of logos in advertisement. Danger signs on vehicles could be detected to trigger warning systems in tunnels, or brand detection on transport vehicles can be used to count company-specific traffic. We present the results of a study on planar pattern detection which is based on keypoint detection and matching of distortion invariant 2d feature descriptors. Specifically we look at the keypoint detectors of type: i) Lowe's DoG approximation from the SURF algorithm, ii) the Harris Corner Detector, iii) the FAST Corner Detector and iv) Lepetit's keypoint detector. Our study then compares the feature descriptors SURF and compact signatures based on Random Ferns: we use 3 sets of sample images to detect and match 3 logos of different structure to find out which combinations of keypoint detector/feature descriptors work well. A real-world test tries to detect vehicles with a distinctive logo in an outdoor environment under realistic lighting and weather conditions: a camera was mounted on a suitable location for observing the entrance to a parking area so that incoming vehicles could be monitored. In this 2 hour long recording we can successfully detect a specific company logo without false positives.

To evaluate the role of the posed smile in overall facial esthetics, as determined by laypersons and orthodontists. Twenty orthodontists and 20 lay evaluators were asked to perform six Q-sorts on different photographs of 48 white female subjects. The six Q-sorts consisted of three different photographs for each of two time points (pre- and posttreatment), as follows: (1) smile-only, (2) face without the smile, and (3) face with the smile. The evaluators determined a split-line for attractive and unattractive images at the end of each Q-sort. The proportions of attractive patients were compared across Q-sorts using a Wilcoxon signed-rank test for paired data. The evaluators also ranked nine facial/dental characteristics at the completion of the six Q-sorts. Evaluators found the pretreatment face without the smile to be significantly more attractive than the face with the smile or the smile-only photographs. Dissimilar results were seen posttreatment; there was not a significant difference between the three posttreatment photographs. The two panels agreed on the proportion of "attractive" subjects but differed on the attractiveness level of each individual subject. The presence of a malocclusion has a negative impact on facial attractiveness. Orthodontic correction of a malocclusion affects overall facial esthetics positively. Laypeople and orthodontists agree on what is attractive. Overall facial harmony is the most important characteristic used in deciding facial attractiveness.
Full Text Available The gripper finger design is a recurring problem in many robotic grasping platforms used in industry. The task of switching the gripper configuration to accommodate for a new batch of objects typically requires engineering expertise, and is a lengthy and costly iterative trial-and-error process. One of the open challenges is the need for the gripper to compensate for uncertainties inherent to the workcell, e.g. due to errors in calibration, inaccurate pose estimation from the vision system, or object deformation. In this paper, we present an analysis of gripper uncertainty compensating capabilities in a sample industrial object grasping scenario for a finger that was designed using an automated simulation-based geometry optimization method (Wolniakowski et al., 2013, 2015. We test the developed gripper with a set of grasps subjected to structured perturbation in a simulation environment and in the real-world setting. We provide a comparison of the data obtained by using both of these approaches. We argue that the strong correspondence observed in results validates the use of dynamic simulation for the gripper finger design and optimization.

Serious illness will inevitably lead to a fundamental emotional reaction. Traditionally, in interventional treatment or rehabilitation trials, the psychological status of patients with implantable cardioverter defibrillators has been evaluated with anxiety and depression as outcome measures. In caring for these patients, the aim of nursing is to help patients manage life with complex heart disease. The early detection and management of negative emotional response might prevent the development of pathological conditions such as depression. The aims of this study were to (a) describe the trajectory of primary emotions over time in patients with implantable cardioverter defibrillators and (b) examine the potential effects of psychoeducational nursing on primary emotions. During the inclusion period (October 2007 to November 2009), 196 patients with implantable cardioverter defibrillator were randomized (1:1) to rehabilitation versus usual care. Rehabilitation consisted of a psychoeducational nursing component and an exercise training component. This article concerns phase 1, psychoeducational nursing, guided by a theory of nursing, Rosemary Rizzo Parses Human Becoming Practice Methodologies. The outcome measure is the Emotions and Health Scale. The scale consists of 8 primary emotions: joy, agreeableness, surprise, fear, sadness, disgust, anger, and anticipation. Mean (SD) age was 58 (13) years, and 79% of the participants were men. Significant improvements were found in primary emotional responses over time (P .05). Primary emotions are affected after implantable cardioverter defibrillator implantation. Improvements over time were found. However, it was not possible to detect any effect of a short-term psychoeducational nursing intervention. Evaluating the primary emotions might be a good way for nurses to monitor patients' psychological outcomes because the instrument is sensitive to changes over a short period. Further development of early psychoeducational nursing

Full Text Available ABTRACT Many persons suffering psychotic illnesses, such as schizophrenia, are largely untreated in low income countries. In these settings, most persons with severe mental illness live with their families. Thus, families play a particular critical role in determining whether a person with a psychotic illness will receive treatment and what the quality of treatment. Psychoeducation has proven to be extremely effective in helping families develop the knowledge and skills which is necessary to help their family members. Indonesia has a national policy to integrate the management of mental health problems into the primary health care system. However, in practice, such care does not implemented effectively. A preliminary study in primary health centers in two districts of Bantul and Gunung Kidul regency, Yogyakarta province, showed that there was very little or there is not any training for health care workers on diagnosis and treatment of psychotic disorder. This study was conducted to evaluate the effectiveness of the training program for health workers in three primary health centers in Yogyakarta, Indonesia, to provide psychoeducation to family caregivers for persons with psychotic disorder. A quasi-experimental study with the approach of one group pre and posttest design was performed in this study. Fortythree health workers in 3 primary health centers in Bantul and Gunung Kidul, Yogyakarta were trained every week for a month to provide psychoeducation to family caregivers who live with psychotic disorder patient. Result showed that the baseline score of knowledge of schizophrenia among health workers in 3 primary health centers in Bantul and Gunung Kidul before training were not significantly different (p=0.162. After the psychoeducation training program there were significantly different (p=0.003 of the score of knowledge of schizophrenia among health workers in 3 primary health care centers compared with before training. For conclusion, the
Full Text Available Abstract Background Most fibromyalgia patients are seen in primary care (PC. However, the effectiveness of the treatments prescribed by general practitioners is usually minimal.

We therefore designed a treatment strategy combining risperidone LAI and COMPASS (COMprehensive Psycho-educational Approach and Scheme Set, an original psychoeducational program supporting treatment with risperidone LAI and evaluating subjective treatment satisfaction, transition of symptoms, and effectiveness in preventing symptomatic relapse. The aim of this study was to examine whether addition of COMPASS to risperidone LAI was more effective in preventing relapse in schizophrenia patients than risperidone LAI alone, with the latter group consisting of patients enrolled in a Phase III trial of risperidone LAI in Japan. Patients were followed up for 6 months, with COMPASS continuously implemented from the transition to the observation phase. The primary efficacy measurements were relapse rate (rates of rehospitalization and discontinuation due to inefficacy. Secondary efficacy measurements were the Brief Psychiatric Rating Scale (BPRS and Global Assessment of Functioning (GAF scores. Of the 96 patients originally enrolled, 19 (19.8% were discontinued from all causes. During the 6-month study period, ten of the 96 patients (10.4% relapsed, compared with a 12.2% relapse rate in patients enrolled in a Phase III trial of risperidone LAI in Japan. Patients showed significant improvements in BPRS total
Full Text Available Interactions at the molecular level in the cellular environment play a very crucial role in maintaining the physiological functioning of the cell. These molecular interactions exist at varied levels viz. protein-protein interactions, protein-nucleic acid interactions or protein-small molecules interactions. Presently in the field, these interactions and their mechanisms mark intensively studied areas. Molecular interactions can also be studied computationally using the approach named as Molecular Docking. Molecular docking employs search algorithms to predict the possible conformations for interacting partners and then calculates interaction energies. However, docking proposes number of solutions as different docked poses and hence offers a serious challenge to identify the native (or near native structures from the pool of these docked poses. Here, we propose a rigorous scoring scheme called DockScore which can be used to rank the docked poses and identify the best docked pose out of many as proposed by docking algorithm employed. The scoring identifies the optimal interactions between the two protein partners utilising various features of the putative interface like area, short contacts, conservation, spatial clustering and the presence of positively charged and hydrophobic residues. DockScore was first trained on a set of 30 protein-protein complexes to determine the weights for different parameters. Subsequently, we tested the scoring scheme on 30 different protein-protein complexes and native or near-native structure were assigned the top rank from a pool of docked poses in 26 of the tested cases. We tested the ability of DockScore to discriminate likely dimer interactions that differ substantially within a homologous family and also demonstrate that DOCKSCORE can distinguish correct pose for all 10 recent CAPRI targets.
Full Text Available Driver assistant systems enhance traffic safety and efficiency. The accurate 3D pose of a front vehicle can help a driver to make the right decision on the road. We propose a novel real-time system to estimate the 3D pose of the front vehicle. This system consists of two parallel threads: vehicle rear tracking and mapping. The vehicle rear is first identified in the video captured by an onboard camera, after license plate localization and foreground extraction. The 3D pose estimation technique is then employed with respect to the extracted vehicle rear. Most current 3D pose estimation techniques need prior models or a stereo initialization with user cooperation. It is extremely difficult to obtain prior models due to the varying appearance of vehicles' rears. Moreover, it is unsafe to ask for drivers' cooperation when a vehicle is running. In our system, two initial keyframes for stereo algorithms are automatically extracted by vehicle rear detection and tracking. Map points are defined as a collection of point features extracted from the vehicle's rear with their 3D information. These map points are inferences that relate the 2D features detected in following vehicles' rears with the 3D world. The relative 3D pose of the onboard camera to the front vehicle rear is then estimated through matching the map points with point features detected on the front vehicle rear. We demonstrate the capabilities of our system by testing on real-time and synthesized videos. In order to make the experimental analysis visible, we demonstrated an estimated 3D pose through augmented reality, which needs accurate and real-time 3D pose estimation.

Full Text Available This work shows the relationship between the development of mathematical thinking and creativity with mathematical problem posing and solving. Creativity and mathematics are disciplines that do not usually appear together. Both concepts constitute complex processes sharing elements, such as fluency (number of ideas, flexibility (range of ideas, novelty (unique idea and elaboration (idea development. These factors contribute, among others, to the fact that schoolchildren are competent in mathematics. The problem solving and posing are a very powerful evaluation tool that shows the mathematical reasoning and creative level of a person. Creativity is part of the mathematics education and is a necessary ingredient to perform mathematical assignments. This contribution presents some important research works about problem posing and solving related to the development of mathematical knowledge and creativity. To that end, it is based on various beliefs reflected in the literature with respect to notions of creativity, problem solving and posing.

With the advantages of wide range, non-contact and high flexibility, the visual estimation technology of target pose has been widely applied in modern industry, robot guidance and other engineering practices. However, due to the influence of complicated industrial environment, outside interference factors, lack of object characteristics, restrictions of camera and other limitations, the visual estimation technology of target pose is still faced with many challenges. Focusing on the above problems, a pose estimation method of the industrial objects is developed based on 3D models of targets. By matching the extracted shape characteristics of objects with the priori 3D model database of targets, the method realizes the recognition of target. Thus a pose estimation of objects can be determined based on the monocular vision measuring model. The experimental results show that this method can be implemented to estimate the position of rigid objects based on poor images information, and provides guiding basis for the operation of the industrial robot.

This paper presents a novel approach for hand matching that achieves significantly improved performance even in the presence of large hand pose variations. The proposed method utilizes a 3-D digitizer to simultaneously acquire intensity and range images of the user's hand presented to the system in an arbitrary pose. The approach involves determination of the orientation of the hand in 3-D space followed by pose normalization of the acquired 3-D and 2-D hand images. Multimodal (2-D as well as 3-D) palmprint and hand geometry features, which are simultaneously extracted from the user's pose normalized textured 3-D hand, are used for matching. Individual matching scores are then combined using a new dynamic fusion strategy. Our experimental results on the database of 114 subjects with significant pose variations yielded encouraging results. Consistent (across various hand features considered) performance improvement achieved with the pose correction demonstrates the usefulness of the proposed approach for hand based biometric systems with unconstrained and contact-free imaging. The experimental results also suggest that the dynamic fusion approach employed in this work helps to achieve performance improvement of 60% (in terms of EER) over the case when matching scores are combined using the weighted sum rule.

Variance pose is an important research topic in face recognition. The alteration of distance parameters across variance pose face features is a challenging. We provide a solution for this problem using perspective projection for variance pose face recognition. Our method infers intrinsic camera parameters of the image which enable the projection of the image plane into 3D. After this, face box tracking and centre of eyes detection can be identified using our novel technique to verify the virtual face feature measurements. The coordinate system of the perspective projection for face tracking allows the holistic dimensions for the face to be fixed in different orientations. The training of frontal images and the rest of the poses on FERET database determine the distance from the centre of eyes to the corner of box face. The recognition system compares the gallery of images against different poses. The system initially utilises information on position of both eyes then focuses principally on closest eye in order to gather data with greater reliability. Differentiation between the distances and position of the right and left eyes is a unique feature of our work with our algorithm outperforming other state of the art algorithms thus enabling stable measurement in variance pose for each individual.

Head poses can be automatically estimated using manifold learning algorithms, with the assumption that with the pose being the only variable, the face images should lie in a smooth and low-dimensional manifold. However, this estimation approach is challenging due to other appearance variations related to identity, head location in image, background clutter, facial expression, and illumination. To address the problem, we propose to incorporate supervised information (pose angles of training samples) into the process of manifold learning. The process has three stages: neighborhood construction, graph weight computation and projection learning. For the first two stages, we redefine inter-point distance for neighborhood construction as well as graph weight by constraining them with the pose angle information. For Stage 3, we present a supervised neighborhood-based linear feature transformation algorithm to keep the data points with similar pose angles close together but the data points with dissimilar pose angles far apart. The experimental results show that our method has higher estimation accuracy than the other state-of-art algorithms and is robust to identity and illumination variations.

This paper presents a pose estimation method based on the 1-Point RANSAC EKF (Extended Kalman Filter) framework. The method fuses the depth data from a LIDAR and the visual data from a monocular camera to estimate the pose of a Unmanned Ground Vehicle (UGV) in a GPS denied environment. Its estimation framework continuy updates the vehicle's 6D pose state and temporary estimates of the extracted visual features' 3D positions. In contrast to the conventional EKF-SLAM (Simultaneous Localization And Mapping) frameworks, the proposed method discards feature estimates from the extended state vector once they are no longer observed for several steps. As a result, the extended state vector always maintains a reasonable size that is suitable for online calculation. The fusion of laser and visual data is performed both in the feature initialization part of the EKF-SLAM process and in the motion prediction stage. A RANSAC pose calculation procedure is devised to produce pose estimate for the motion model. The proposed method has been successfully tested on the Ford campus's LIDAR-Vision dataset. The results are compared with the ground truth data of the dataset and the estimation error is ~1.9% of the path length.

Full Text Available Deinstitutionalization processes in recent times have led to a new age in relations between family and mental health professionals. Care professionals were replaced, after the psychiatric reform, for care carried out by the family without the knowledge, information and skills to assume these functions. This is the situation of many families of patients with schizophrenia.Disabling features of schizophrenia usually cause depends on their families, who take care with the consequent impact on their lives. Psychosocial interventions assessing their work and want to build an alliance with them by giving them skills and coping mechanisms to reduce adverse family atmosphere, anticipate and solve problems and reduce the expressions of anger and guilt keeping appropiate expectations. However, these actions must be enforced by providing main caregivers with the skills that enable them to gain control, this is the main target of psychoeducational programs.Today there are many people in favour of such interventions in the early stages of schizophrenia. However, it is no clear how far development of these programs is supported by evidence of effectiveness. So it has proposed a psychosocial and psychoeducational program aimed at main caregivers of patients with schizophrenia in early stages. This program will be led by a psychiatric nurse in collaboration with other professionals in the interdisciplinary team; psychiatrist, clinical psychologist and social worker. It has developed clinical trial with a control group who will receive the gide for families, caregivers and people affected, "Cómo afrontar la esquizofrenia," and an experimental group will receive, in addition to the guide, the group intervention sessions.
Full Text Available Abstract Background Family psychoeducation is a relatively simple and straightforward intervention whose prophylactic effectiveness and cost-effectiveness is well-established for schizophrenia. We have recently demonstrated its effectiveness for unipolar depression, but its cost-effectiveness has never been examined. We hereby report a cost-effectiveness analysis alongside a randomized controlled trial in order to assess its cost-effectiveness for preventing relapse/recurrence in depression. Methods Fifty-seven patients diagnosed with major depression and undergoing its maintenance treatment, and their primary family members were randomized to treatment as usual (TAU only or to TAU plus family psychoeducation, which consisted of four 2-hour multiple-family sessions consisting of didactic lectures about depression (30 minutes and group discussion and problem solving (60–90 minutes. The economic analyses were undertaken from the perspective of the National Health Insurance (NHI, assuming the most reasonable price of US$50 per psychoeducation session per patient. The main outcome measures included relapse-free days and direct costs to the NHI. Results The intervention group enjoyed 272 (SD: 7.1 relapse-free days, while the control group spent 214 (SD: 90.8 relapse-free days (Cox proportional hazard ratio = 0.17, 95%CI: 0.04 to 0.75, p = 0.002. Cost-effectiveness acceptability curves suggested that the family psychoeducation has 90% or more chances of being cost-effective if the decision-maker is prepared to pay US$20 for one additional relapse-free day. This cost-effectiveness finding was robust when the price for family psychoeducation ranged between 50% to 150% of the baseline scenario in sensitivity analyses. If a relapse-free day is considered to be worth $30 or more, all the pricing scenarios have a close to 100% probability of being cost-effective. Conclusion Family psychoeducation is effective in the relapse prevention of

Learned resourcefulness plays a significant role in facilitating maternal coping during the transition to motherhood. Given the growing evidence of perinatal depression and the frequent feeling of incompetence in the maternal role, the implementation of an effective intervention to promote maternal role competence and emotional well-being is essential. To determine the impact of a childbirth psychoeducation program based on the concept of learned resourcefulness on maternal role competence and depressive symptoms in Chinese childbearing women. A pretest-posttest, control group quasi-experimental design with repeated measures was used. The study was conducted in two regional public hospitals in Hong Kong that provide routine childbirth education programs with similar content and structure. One hospital was being randomly selected as the experimental hospital. A convenience sample of 184 Chinese pregnant women attending the childbirth education was recruited between October 2005 and April 2007. Inclusion criteria were primiparous with singleton and uneventful pregnancy, at gestation between 12 and 35 weeks, and did not have a past or familial psychiatric illness. The intervention was a childbirth psychoeducation program that was incorporated into the routine childbirth education in the experimental hospital. The experimental group (n=92) received the childbirth psychoeducation program and the routine childbirth education. The comparison group (n=92) received the routine childbirth education alone in the comparison hospital. Outcomes were measured by the Self-Control Schedule, Parenting Sense of Competence Scale-Efficacy subscale and Edinburgh Postnatal Depression Scale at baseline, immediately post-intervention, at 6 weeks and 6 months postpartum. Analysis was by intention to treat. Women receiving the childbirth psychoeducation program had significant improvement in learned resourcefulness at 6 weeks postpartum (p=0.004) and an overall reduction in depressive

Face images captured in unconstrained environments usually contain significant pose variation, which dramatically degrades the performance of algorithms designed to recognize frontal faces. This paper proposes a novel face identification framework capable of handling the full range of pose variations within ±90° of yaw. The proposed framework first transforms the original pose-invariant face recognition problem into a partial frontal face recognition problem. A robust patch-based face representation scheme is then developed to represent the synthesized partial frontal faces. For each patch, a transformation dictionary is learnt under the proposed multi-task learning scheme. The transformation dictionary transforms the features of different poses into a discriminative subspace. Finally, face matching is performed at patch level rather than at the holistic level. Extensive and systematic experimentation on FERET, CMU-PIE, and Multi-PIE databases shows that the proposed method consistently outperforms single-task-based baselines as well as state-of-the-art methods for the pose problem. We further extend the proposed algorithm for the unconstrained face verification problem and achieve top-level performance on the challenging LFW data set.

Temporal subtraction techniques using 2D image registration improve the detectability of interval changes from chest radiographs. Although such methods are well known for some time they are not widely used in radiologic practice. The reason is the occurrence of strong pose differences between two acquisitions with a time interval of months to years in between. Such strong perspective differences occur in a reasonable number of cases. They cannot be compensated by available image registration methods and thus mask interval changes to be undetectable. In this paper a method is proposed to estimate a 3D pose difference by the adaptation of a 3D rib cage model to both projections. The difference between both is then compensated for, thus producing a subtraction image with virtually no change in pose. The method generally assumes that no 3D image data is available from the patient. The accuracy of pose estimation is validated with chest phantom images acquired under controlled geometric conditions. A subtle interval change simulated by a piece of plastic foam attached to the phantom becomes visible in subtraction images generated with this technique even at strong angular pose differences like an anterior-posterior inclination of 13 degrees.

Doppler ultrasound is a non-invasive diagnostic tool for the quantitative measurement of blood flow. However, given that it provides velocity data that is dependent on the location and angle of measurement, repeat measurements to detect problems over time may require an expert to return to the same location. We therefore developed an image-guidance system based on ultrasound B-mode images that enables an inexperienced user to position the ultrasound probe at the same site repeatedly in order to acquire a comparable time series of Doppler readings. The system utilizes a bioresorbable fiducial and complementing software composed of the fiducial detection, key points tracking, probe pose estimation, and graphical user interface (GUI) modules. The fiducial is an echogenic marker that is implanted at the surgical site and can be detected and tracked during ultrasound B-mode screening. The key points on the marker can next be used to determine the pose of the ultrasound probe with respect to the marker. The 3D representation of the probe with its position and orientation are then displayed in the GUI for the user guidance. The fiducial detection has been tested on the data sets collected from three animal studies. The pose estimation algorithm was validated by five data sets collected by a UR5 robot. We tested the system on a plastisol phantom and showed that it can detect and track the fiducial marker while displaying the probe pose in real-time.

C-arm fluoroscopy is used for guidance during several clinical exams, e.g. in bronchoscopy to locate the bronchoscope inside the airways. Unfortunately, these images provide only 2D information. However, if the C-arm pose is known, it can be used to overlay the intrainterventional fluoroscopy images with 3D visualizations of airways, acquired from preinterventional CT images. Thus, the physician's view is enhanced and localization of the instrument at the correct position inside the bronchial tree is facilitated. We present a novel method for C-arm pose estimation introducing a marker-based pattern, which is placed on the patient table. The steel markers form a pattern, allowing to deduce the C-arm pose by use of the projective invariant cross-ratio. Simulations show that the C-arm pose estimation is reliable and accurate for translations inside an imaging area of 30 cm x 50 cm and rotations up to 30°. Mean error values are 0.33 mm in 3D space and 0.48 px in the 2D imaging plane. First tests on C-arm images resulted in similarly compelling accuracy values and high reliability in an imaging area of 30 cm x 42.5 cm. Even in the presence of interfering structures, tested both with anatomy phantoms and a turkey cadaver, high success rates over 90% and fully satisfying execution times below 4 sec for 1024 px × 1024 px images could be achieved.

Three-dimensional (3D) face models can intrinsically handle large pose face recognition problem. In this paper, we propose a novel pose-invariant face recognition method via RGB-D images. By employing depth, our method is able to handle self-occlusion and deformation, both of which are challenging problems in two-dimensional (2D) face recognition. Texture images in the gallery can be rendered to the same view as the probe via depth. Meanwhile, depth is also used for similarity measure via frontalization and symmetric filling. Finally, both texture and depth contribute to the final identity estimation. Experiments on Bosphorus, CurtinFaces, Eurecom, and Kiwi databases demonstrate that the additional depth information has improved the performance of face recognition with large pose variations and under even more challenging conditions.

Full Text Available When we see a human sitting down, standing up, or walking, we can recognise one of these poses independently of the individual, or we can recognise the individual person, independently of the pose. The same issues arise for deforming objects. For example, if we see a flag deformed by the wind, either blowing out or hanging languidly, we can usually recognise the flag, independently of its deformation; or we can recognise the deformation independently of the identity of the flag. We hypothesize that these types of recognition can be implemented by the primate visual system using temporo-spatial continuity as objects transform as a learning principle. In particular, we hypothesize that pose or deformation can be learned under conditions in which large numbers of different people are successively seen in the same pose, or objects in the same deformation. We also hypothesize that person-specific representations that are independent of pose, and object-specific representations that are independent of deformation and view, could be built, when individual people or objects are observed successively transforming from one pose or deformation and view to another. These hypotheses were tested in a simulation of the ventral visual system, VisNet, that uses temporal continuity, implemented in a synaptic learning rule with a short-term memory trace of previous neuronal activity, to learn invariant representations. It was found that depending on the statistics of the visual input, either pose-specific or deformation-specific representations could be built that were invariant with respect to individual and view; or that identity-specific representations could be built that were invariant with respect to pose or deformation and view. We propose that this is how pose-specific and pose-invariant, and deformation-specific and deformation-invariant, perceptual representations are built in the brain.

Full Text Available Research on beneficial consequences of yoga focuses on the effects of yogic breathing and meditation. Less is known about the psychological effects of performing yoga postures. The present study investigated the effects of yoga poses on subjective sense of energy and self-esteem. The effects of yoga postures were compared to the effects of ‘power poses,’ which arguably increase the sense of power and self-confidence due to their association with interpersonal dominance (Carney et al., 2010. The study tested the novel prediction that yoga poses, which are not associated with interpersonal dominance but increase bodily energy, would increase the subjective feeling of energy and therefore increase self-esteem compared to ‘high power’ and ‘low power’ poses. A two factorial, between participants design was employed. Participants performed either two standing yoga poses with open front of the body (n = 19, two standing yoga poses with covered front of the body (n = 22, two expansive, high power poses (n = 21, or two constrictive, low power poses (n = 20 for 1-min each. The results showed that yoga poses in comparison to ‘power poses’ increased self-esteem. This effect was mediated by an increased subjective sense of energy and was observed when baseline trait self-esteem was controlled for. These results suggest that the effects of performing open, expansive body postures may be driven by processes other than the poses’ association with interpersonal power and dominance. This study demonstrates that positive effects of yoga practice can occur after performing yoga poses for only 2 min.

Little evidence exists regarding efficacious HIV and sexually transmitted infections (STI) prevention interventions with internally displaced populations. Internally displaced women are at elevated risk for HIV/STI due to limited access to health services, heightened poverty and social network breakdown. The FASY (Famn an Aksyon Pou Sante' Yo) (Women Taking Action For Their Health) study examined the effectiveness of a peer health worker (PHW) delivered psycho-educational HIV/STI pilot study with internally displaced women in Leogane, Haiti. This was a non-randomized cohort pilot study. Participants completed a computer-assisted pre-test programmed on Android tablet PCs followed by an HIV/STI educational video-based session and a 6-week psycho-educational group program of weekly meetings. Participants completed a post-test upon completion of group sessions. The primary outcome was HIV knowledge; our pre-specified index of clinically significant change was an effect size of 0.30. Secondary outcomes included: STI knowledge, condom use, social support, resilient coping, depression and relationship control. We used mixed-effects regression to calculate mean outcome pre-post score change. This study was registered (clinicaltrials.gov, NCT01492829). Between January 1-April 30, 2012 we assigned 200 participants to the study. The majority of participants (n = 176, 88%) completed the study and were followed up at 8 weeks, finishing April 30, 2012. Adjusted for socio-demographic characteristics, HIV knowledge (β = 4.81; 95% CI 4.36-5.26), STI knowledge (β = 0.84; 95% CI 0.70-0.99), condom use (AOR = 4.05, 95% CI 1.86-8.83), and depression (β = -0.63, 95% CI -0.88--0.39) scores showed statistically significant change post-intervention (pHaiti.

Online sexual offenders represent an increasingly large proportion of all sexual offenders. Many of these offenders receive noncustodial sentences, and there is a growing need for community-based interventions. The aim of this study was to evaluate a psycho-educational program for community dwelling users of child sexual exploitation material (CSEM). A total of 92 adult male participants completed self-report measures at pre and post. A subset of participants also completed measures after a follow-up period. Results suggested benefits across depression, anxiety, and stress; social competency, including locus of control and self-esteem; and distorted attitudes. Furthermore, these effects remained 8 to 12 weeks following program completion. Our results suggest that CSEM users are amenable to treatment in the community and that there are beneficial outcomes in affective and interpersonal functioning following psycho-education. These factors represent treatment targets for sexual offenders and are recognized risk factors for contact sexual offense recidivism.

One of the key challenges for current face recognition techniques is how to handle pose variations between the probe and gallery face images. In this paper, we present a method for reconstructing the virtual frontal view from a given nonfrontal face image using Markov random fields (MRFs) and an efficient variant of the belief propagation algorithm. In the proposed approach, the input face image is divided into a grid of overlapping patches, and a globally optimal set of local warps is estimated to synthesize the patches at the frontal view. A set of possible warps for each patch is obtained by aligning it with images from a training database of frontal faces. The alignments are performed efficiently in the Fourier domain using an extension of the Lucas-Kanade algorithm that can handle illumination variations. The problem of finding the optimal warps is then formulated as a discrete labeling problem using an MRF. The reconstructed frontal face image can then be used with any face recognition technique. The two main advantages of our method are that it does not require manually selected facial landmarks or head pose estimation. In order to improve the performance of our pose normalization method in face recognition, we also present an algorithm for classifying whether a given face image is at a frontal or nonfrontal pose. Experimental results on different datasets are presented to demonstrate the effectiveness of the proposed approach.

Spontaneous and posed emotional facial expressions in individuals with Parkinson's disease (PD, n = 12) were compared with those of healthy age-matched controls (n = 12). The intensity and amount of facial expression in PD patients were expected to be reduced for spontaneous but not posed expressions. Emotional stimuli were video clips selected from films, 2-5 min in duration, designed to elicit feelings of happiness, sadness, fear, disgust, or anger. Facial movements were coded using Ekman and Friesen's (1978) Facial Action Coding System (FACS). In addition, participants rated their emotional experience on 9-point Likert scales. The PD group showed significantly less overall facial reactivity than did controls when viewing the films. The predicted Group X Condition (spontaneous vs. posed) interaction effect on smile intensity was found when PD participants with more severe disease were compared with those with milder disease and with controls. In contrast, ratings of emotional experience were similar for both groups. Depression was positively associated with emotion rating but not with measures of facial activity. Spontaneous facial expression appears to be selectively affected in PD, whereas posed expression and emotional experience remain relatively intact.

This paper proposes a relative pose estimation approach based on object contour model. The first step is to obtain a two-dimensional (2D) projection of three-dimensional (3D)-model-based target, which will be divided into 40 forms by clustering and LDA analysis. Then we proceed by extracting the target contour in each image and computing their Pseudo-Zernike Moments (PZM), thus a model library is constructed in an offline mode. Next, we spot a projection contour that resembles the target silhouette most in the present image from the model library with reference of PZM; then similarity transformation parameters are generated as the shape context is applied to match the silhouette sampling location, from which the identification parameters of target can be further derived. Identification parameters are converted to relative pose parameters, in the premise that these values are the initial result calculated via iterative refinement algorithm, as the relative pose parameter is in the neighborhood of actual ones. At last, Distance Image Iterative Least Squares (DI-ILS) is employed to acquire the ultimate relative pose parameters.

An optical neural network architecture and algorithm based on a Hopfield optimization network are presented for multitarget tracking. This tracker utilizes a neuron for every possible target track, and a quadratic energy function of neural activities which is minimized using gradient descent neural evolution. The neural net tracker is demonstrated as part of a system for determining position and orientation (pose) of spinning satellites with respect to a robotic spacecraft. The input to the system is time sequence video from a single camera. Novelty detection and filtering are utilized to locate and segment novel regions from the input images. The neural net multitarget tracker determines the correspondences (or tracks) of the novel regions as a function of time, and hence the paths of object (satellite) parts. The path traced out by a given part or region is approximately elliptical in image space, and the position, shape and orientation of the ellipse are functions of the satellite geometry and its pose. Having a geometric model of the satellite, and the elliptical path of a part in image space, the three-dimensional pose of the satellite is determined. Digital simulation results using this algorithm are presented for various satellite poses and lighting conditions.

One of the difficulties of students in the learning of geometry is on the subject of plane that requires students to understand the abstract matter. The aim of this research is to determine the effect of Problem Posing learning model with Realistic Mathematics Education Approach in geometry learning. This quasi experimental research was conducted in one of the junior high schools in Karanganyar, Indonesia. The sample was taken using stratified cluster random sampling technique. The results of this research indicate that the model of Problem Posing learning with Realistic Mathematics Education Approach can improve students’ conceptual understanding significantly in geometry learning especially on plane topics. It is because students on the application of Problem Posing with Realistic Mathematics Education Approach are become to be active in constructing their knowledge, proposing, and problem solving in realistic, so it easier for students to understand concepts and solve the problems. Therefore, the model of Problem Posing learning with Realistic Mathematics Education Approach is appropriately applied in mathematics learning especially on geometry material. Furthermore, the impact can improve student achievement.

To examine the information and communication technology (ICT) features of psychoeducational interventions for depression delivered via the Internet or via mobile technology. Web- and mobile-based psychoeducational intervention studies published from 2004 to 2014 were selected and reviewed by two independent coders. A total of 55 unique studies satisfied the selection criteria. The review revealed a diverse range of ICTs used to support the psychoeducational programs. Most interventions used websites as their main mode of delivery and reported greater use of communication tools compared to effective approaches like tailoring or interactive technologies games, videos, and self-monitoring tools. Many of the studies relied on medium levels of clinician involvement and only a few were entirely self-guided. Programs that reported higher levels of clinician involvement also reported using more communication tools, and reported greater compliance to treatment. Future experimental studies may help unpack the effects of technology features and reveal new ways to automate aspects of clinician input. There is a need to further examine ways ICTs can be optimized to reduce the burden on clinicians whilst enhancing the delivery of proven effective therapeutic approaches.

The aim of the study was to investigate the influence of motivational and targeted psychoeducational programs designed for patients with paranoid schizophrenia with abdominal obesity. We observed 34 women aged 18-42 with continuous-flow type paranoid schizophrenia. All patients had a concomitant abdominal obesity, which developed secondarily after long-term administration of second generation antipsychotic medications (at least 1 year). Based on clinical-psychopathological and psychometric methods of assessment and on the analysis of Treatment Satisfaction Questionnaire we have developed modules for psychoeducational programs. Based on the results of the treatment we conclude that the application of psychoeducational programs is an effective component of complex treatment of patients with paranoid schizophrenia. Abdominal obesity should be regarded as an important and the main side effect of long-term therapy with atypical antipsychotic medications. It has a marked negative effect on subjective assessment of patients and decreases the level of their mental and social adaptation. This factor should be the basis for the formation of re-socialization and compliance-oriented actions.
Full Text Available Abstract Background Brief family intervention may have a positive impact on family caregivers for patients with mental disorders. We assessed the effectiveness of a group psycho-educational program on family caregivers for patients with schizophrenia and mood disorders. Methods This randomized controlled trial was performed on 100 caregivers for patients with mental disorders attending the Isfahan Behavioral Sciences Research Center (IBSRC, in Isfahan, Iran. One hundred family caregivers of patients with schizophrenia (n = 50 and mood disorders (n = 50 were selected and assigned randomly to either a psycho-educational group intervention or routine care in each diagnosis category. The caregivers were followed for 3 months. Caregiver burden was assessed using the Zarit Burden Interview Results The mean scores of the Zarit caregiver burden decreased significantly for the group that participated in the psycho-educational program, while scores in the control group did not change significantly. Conclusions This group intervention program was effective to reduce the caregiver burden for both categories of mental disorders in the Iranian population. This group intervention program may improve the quality of life of patients and caregivers by improving the standards of care giving. Trial registration RCT registration number: IRCT138804272200N

Learning discriminant face representation for pose-invariant face recognition has been identified as a critical issue in visual learning systems. The challenge lies in the drastic changes of facial appearances between the test face and the registered face. To that end, we propose a high-level feature learning framework called "collaborative random faces (RFs)-guided encoders" toward this problem. The contributions of this paper are three fold. First, we propose a novel supervised autoencoder that is able to capture the high-level identity feature despite of pose variations. Second, we enrich the identity features by replacing the target values of conventional autoencoders with random signals (RFs in this paper), which are unique for each subject under different poses. Third, we further improve the performance of the framework by incorporating deep convolutional neural network facial descriptors and linking discriminative identity features from different RFs for the augmented identity features. Finally, we conduct face identification experiments on Multi-PIE database, and face verification experiments on labeled faces in the wild and YouTube Face databases, where face recognition rate and verification accuracy with Receiver Operating Characteristic curves are rendered. In addition, discussions of model parameters and connections with the existing methods are provided. These experiments demonstrate that our learning system works fairly well on handling pose variations.

Estimating the values of unknown parameters from corrupted measured data faces a lot of challenges in ill-posed problems. In such problems, many fundamental estimation methods fail to provide a meaningful stabilized solution. In this work, we propose a new regularization approach and a new regularization parameter selection approach for linear least-squares discrete ill-posed problems. The proposed approach is based on enhancing the singular-value structure of the ill-posed model matrix to acquire a better solution. Unlike many other regularization algorithms that seek to minimize the estimated data error, the proposed approach is developed to minimize the mean-squared error of the estimator which is the objective in many typical estimation scenarios. The performance of the proposed approach is demonstrated by applying it to a large set of real-world discrete ill-posed problems. Simulation results demonstrate that the proposed approach outperforms a set of benchmark regularization methods in most cases. In addition, the approach also enjoys the lowest runtime and offers the highest level of robustness amongst all the tested benchmark regularization methods.

This paper presents a multi-camera system that performs face detection and pose estimation in real-time and may be used for intelligent computing within a visual sensor network for surveillance or human-computer interaction. The system consists of a Scene View Camera (SVC), which operates at a fixed zoom level, and an Object View Camera (OVC), which continuously adjusts its zoom level to match objects of interest. The SVC is set to survey the whole filed of view. Once a region has been identified by the SVC as a potential object of interest, e.g. a face, the OVC zooms in to locate specific features. In this system, face candidate regions are selected based on skin color and face detection is accomplished using a Support Vector Machine classifier. The locations of the eyes and mouth are detected inside the face region using neural network feature detectors. Pose estimation is performed based on a geometrical model, where the head is modeled as a spherical object that rotates upon the vertical axis. The triangle formed by the mouth and eyes defines a vertical plane that intersects the head sphere. By projecting the eyes-mouth triangle onto a two dimensional viewing plane, equations were obtained that describe the change in its angles as the yaw pose angle increases. These equations are then combined and used for efficient pose estimation. The system achieves real-time performance for live video input. Testing results assessing system performance are presented for both still images and video.

Full Text Available High-precision wind tunnel simulation tests play an important role in aircraft design and manufacture. In this study, a high-speed pose vision measurement method is proposed for high-speed and rolling targets in a supersonic wind tunnel. To obtain images with high signal-to-noise ratio and avoid impacts on the aerodynamic shape of the rolling targets, a high-speed image acquisition method based on ultrathin retro-reflection markers is presented. Since markers are small-sized and some of them may be lost when the target is rolling, a novel markers layout with which markers are distributed evenly on the surface is proposed based on a spatial coding method to achieve highly accurate pose information. Additionally, a pose acquisition is carried out according to the mentioned markers layout after removing mismatching points by Case Deletion Diagnostics. Finally, experiments on measuring the pose parameters of high-speed targets in the laboratory and in a supersonic wind tunnel are conducted to verify the feasibility and effectiveness of the proposed method. Experimental results indicate that the position measurement precision is less than 0.16 mm, the pitching and yaw angle precision less than 0.132° and the roll angle precision 0.712°.

Full Text Available It is important for pre-service teachers to know the conceptual difficulties they have experienced regarding the concepts of multiplication and division in fractions and problem posing is a way to learn these conceptual difficulties. Problem posing is a synthetic activity that fundamentally has multiple answers. The purpose of this study is to analyze the multiplication and division of fractions problems posed by pre-service elementary mathematics teachers and to investigate how the problems posed change according to the year of study the pre-service teachers are in. The study employed developmental research methods. A total of 213 pre-service teachers enrolled in different years of the Elementary Mathematics Teaching program at a state university in Turkey took part in the study. The “Problem Posing Test” was used as the data collecting tool. In this test, there are 3 multiplication and 3 division operations. The data were analyzed using qualitative descriptive analysis. The findings suggest that, regardless of the year, pre-service teachers had more conceptual difficulties in problem posing about the division of fractions than in problem posing about the multiplication of fractions.

Psychoeducational interventions, tested for efficacy in randomized clinical trials, are seldom implemented in clinical practice where cancer survivors and their family caregivers can benefit from them. This study examined the effectiveness of the FOCUS Program on cancer survivors' and their family caregivers' outcomes when implemented at a Cancer Support Community (CSC) affiliate by agency social workers. Study aims were to (1) test effects of the program on survivor and caregiver outcomes as a unit and (2) determine program feasibility in terms of enrollment, retention, intervention fidelity, and satisfaction. A preintervention and postintervention pilot effectiveness study was conducted with 34 cancer survivor-caregiver dyads (ie, pairs). The FOCUS Program, originally delivered by nurses in dyads' homes, was modified to a small-group format and delivered by CSC social workers. The primary outcome was quality of life (QOL). Intermediary outcomes were benefits of illness/caregiving, communication, support, and self-efficacy. Analyses included repeated-measures analysis of variance. Dyads had significant improvements in total QOL; physical, emotional, and functional QOL; benefits of illness; and self-efficacy. Effect sizes were similar to prior randomized clinical trial findings. Although dyads were difficult to recruit (enrollment, 60%), both retention (92%) and intervention fidelity (94%) were high. It was possible to implement the FOCUS Program at a CSC affiliate by agency staff, obtain positive intervention effects, and maintain intervention fidelity. Researchers and clinicians need to collaborate to implement more evidence-based interventions in practice settings for cancer survivors and their family caregivers.

Psycho-education can reduce childbirth fear and caesarean section numbers. This study determines the cost-effectiveness of a midwife-led psycho-education intervention for women fearful of birth. One thousand four hundred ten pregnant women in south-east Queensland, Australia were screened for childbirth fear (W-DEQ A ≥ 66). Women with high scores (n = 339) were randomised to the BELIEF Study (Birth Emotions and Looking to Improve Expectant Fear) to receive psycho-education (n = 170) at 24 and 34 weeks of pregnancy or to the control group (n = 169). Women in both groups were surveyed 6 weeks postpartum with total cost for health service use during pregnancy calculated. Logistic regression models assessed the odds ratio of having vaginal birth or caesarean section in the study groups. Of 339 women randomised, 184 (54%) women returned data at 6 weeks postpartum (Intervention Group n = 91; Control Group n = 93). Women receiving psycho-education had a higher likelihood of vaginal birth compared to controls (n = 60, 66% vs. n = 54, 58%; OR 2.34). Mean 'treatment' cost for women receiving psycho-education was AUS$72. Mean cost for health services excluding the cost of psycho-education, was less in the intervention group (AUS$1193 vs. AUS$1236), but not significant (p = 0.78). For every five women who received midwife counselling, one caesarean section was averted. The incremental healthcare cost to prevent one caesarean section using this intervention was AUS$145. Costs of delivering midwife psycho-education to women with childbirth fear during pregnancy are offset by improved vaginal birth rates and reduction in caesarean section numbers.

Full Text Available E-health, and in particular smartphone based technology, is increasingly becoming commonplace in healthcare. Whilst psychiatry has tapped onto these innovations for conditions such as affective disorders as well as schizophrenia and psychosis, the usage of these technologies in addiction is limited. Addiction psychiatry could harness the potential of smartphone technologies. Given the increasing incidences of substance related problems globally, and along with the normalization of the general public’s perspectives towards substances, and also in consideration of unwillingness for at-risk individuals in seeking help, the authors hope to illustrate how these issues could potentially be solved using E-Health and technological innovations. The objectives of the current perspective article are to illustrate how recent advances in smartphone-based technologies could help in terms of psycho-education, as well as in helping individuals who are at-risk users in seeking help earlier. The authors aim to illustrate how the above are possible, building on existing theory driven framework that has been extensively reviewed in previous literature. Limitations with regards to the implementation of such technologies will also be discussed.

The analysis applies Dow's [1986 American Anthropologist 88:56-69] model of universal components of symbolic healing to elucidate sociocultural aspects of therapeutic efficacy that are alternatively disregarded as placebo or nonspecific effects. It is demonstrated how staff engaged with clients to deliver "psychoeducation" that provided scientific and biomedical theories about mental illness, constituting a shared "mythic world" that was accepted as an experiential truth and used to explain clients' illness experiences. The analysis highlights the need to supplement attention in Dow's model to the healing procedure with consideration of variability in the healing process. Depending on individual responses to the intervention, the staff's professional backgrounds and staff-client relationships different recovery models were applied. One suggested "episodic psychosis" and full recovery, and the other suggested "chronic schizophrenia" and the necessity of comprehensive life adjustments to the mental illness. The recovery models influenced clients' perspectives on illness and self as they engaged in identity work, negotiating future plans and individual life projects by including also alternative systems of explanation from the wider cultural repertoire.

E-health, and in particular smartphone-based technology, is increasingly becoming commonplace in healthcare. While psychiatry has tapped onto these innovations for conditions, such as affective disorders, and schizophrenia and psychosis, the usage of these technologies in addiction is limited. Addiction psychiatry could harness the potential of smartphone technologies. Given the increasing incidences of substance-related problems globally, and along with the normalization of the general public's perspectives toward substances, and also in consideration of unwillingness for at-risk individuals in seeking help, the authors hope to illustrate how these issues could potentially be solved using E-health and technological innovations. The objectives of the current perspective article are to illustrate how recent advances in smartphone-based technologies could help in terms of psycho-education, as well as in helping individuals who are at-risk users in seeking help earlier. The authors aim to illustrate how the above are possible, building on existing theory-driven framework that has been extensively reviewed in the previous literature. Limitations with regard to the implementation of such technologies will also be discussed.

Reports an error in "Preparatory power posing affects nonverbal presence and job interview performance" by Amy J. C. Cuddy, Caroline A. Wilmuth, Andy J. Yap and Dana R. Carney ( Journal of Applied Psychology , 2015[Jul], Vol 100, 1286-1295). In the article, the degrees of freedom associated with the three F-tests noted on pages 1289 and 1290 should be 1 and 59 (and not 1 and 60, as previously reported). Also, on p. 1290, in the first sentence under the "Mediation" heading, it should be noted that the dependent variables were regressed onto the mediators, and not the other way around. Finally, in Figures 2 and 3 (on p.interview-preparatory power posing-would enhance performance during the interview. Participants adopted high-power (i.e., expansive, open) poses or low-power (i.e., contractive, closed) poses, and then prepared and delivered a speech to 2 evaluators as part of a mock job interview. All interview speeches were videotaped and coded for overall performance and hireability and for 2 potential mediators: verbal content (e.g., structure, content) and nonverbal presence (e.g., captivating, enthusiastic). As predicted, those who prepared for the job interview with high- (vs. low-) power poses performed better and were more likely to be chosen for hire; this relation was mediated by nonverbal presence, but not by verbal content. Although previous research has focused on how a nonverbal behavior that is enacted during interactions and observed by perceivers affects how those perceivers evaluate and respond to the actor, this experiment focused on how a nonverbal behavior that is enacted before the interaction and unobserved by perceivers affects the actor's performance, which, in turn, affects how perceivers evaluate and respond to the actor. This experiment reveals a theoretically novel and practically informative result that demonstrates the causal relation between preparatory nonverbal behavior and subsequent performance and outcomes.

Full Text Available Abstract Background Prevention of postnatal mental disorders in women is an important component of comprehensive health service delivery because of the substantial potential benefits for population health. However, diverse approaches to prevention of postnatal depression have had limited success, possibly because anxiety and adjustment disorders are also problematic, mental health problems are multifactorially determined, and because relationships amongst psychosocial risk factors are complex and difficult to modify. The aim of this paper is to describe the development of a novel psycho-educational intervention to prevent postnatal mental disorders in mothers of firstborn infants. Methods Data from a variety of sources were synthesised: a literature review summarised epidemiological evidence about neglected modifiable risk factors; clinical research evidence identified successful psychosocial treatments for postnatal mental health problems; consultations with clinicians, health professionals, policy makers and consumers informed the proposed program and psychological and health promotion theories underpinned the proposed mechanisms of effect. The intervention was pilot-tested with small groups of mothers and fathers and their first newborn infants. Results What Were We Thinking! is a psycho-educational intervention, designed for universal implementation, that addresses heightened learning needs of parents of first newborns. It re-conceptualises mental health problems in mothers of infants as reflecting unmet needs for adaptations in the intimate partner relationship after the birth of a baby, and skills to promote settled infant behaviour. It addresses these two risk factors in half-day seminars, facilitated by trained maternal and child health nurses using non-psychiatric language, in groups of up to five couples and their four-week old infants in primary care. It is designed to promote confidence and reduce mental disorders by providing skills

Full Text Available Abstract Background Children who witness interparental violence are at a heightened risk for developing psychosocial, behavioral and cognitive problems, as well as posttraumatic stress symptoms. For these children the psycho-educational secondary prevention program 'En nu ik...!' ('It's my turn now!' has been developed. This program includes specific therapeutic factors focused on emotion awareness and expression, increasing feelings of emotional security, teaching specific coping strategies, developing a trauma narrative, improving parent-child interaction and psycho-education. The main study aim is to evaluate the effectiveness of the specific therapeutic factors in the program. A secondary objective is to study mediating and moderating factors. Methods/design This study is a prospective multicenter randomized controlled trial across cities in the Netherlands. Participants (N = 140 are referred to the secondary preventive intervention program by police, social work, women shelters and youth (mental health care. Children, aged 6-12 years, and their parents, who experienced interparental violence are randomly assigned to either the intervention program or the control program. The control program is comparable on nonspecific factors by offering positive attention, positive expectations, recreation, distraction, warmth and empathy of the therapist, and social support among group participants, in ways that are similar to the intervention program. Primary outcome measures are posttraumatic stress symptoms and emotional and behavioral problems of the child. Mediators tested are the ability to differentiate and express emotions, emotional security, coping strategies, feelings of guilt and parent-child interaction. Mental health of the parent, parenting stress, disturbances in parent-child attachment, duration and severity of the domestic violence and demographics are examined for their moderating effect. Data are collected one week before the program
Background Siblings of individuals with first episode psychosis are natural partners to promote service users’ recovery and are themselves vulnerable to mental ill health due to the negative impact of psychosis within the family. This study aims to develop and undertake a preliminary evaluation of the efficacy of an online multi-component psychoeducational intervention for siblings of individuals with first episode psychosis. The impetus for the intervention arose from siblings' expressed needs for peer support and information on psychosis, coping and management strategies for common symptoms and ways to promote recovery. Methods/Design The project design draws on the Medical Research Council framework for the design and evaluation of complex interventions. Mixed methods comprising collection of qualitative focus group data, systematic review and expert advisory group consultation are used to develop the theoretical basis for and design of the intervention. This protocol focuses on the modelling and piloting phase which uses a randomised controlled trial with factorial design to test the efficacy of the intervention. Outcome data on participants’ mental wellbeing, knowledge, perceived self-efficacy and experiences of caregiving will be assessed at baseline, at end of the intervention (10 weeks later) and at 10 week follow-up. In addition, a post-intervention semi-structured interview with 20% of the participants will explore their experiences and acceptability of the intervention. Discussion This multi-component online psychoeducational intervention aims to enhance siblings' knowledge about psychosis and their coping capacity, thus potentially improving their own mental wellbeing and promoting their contribution to service users’ recovery. The factorial design randomised controlled trial with a supplementary process evaluation using semi-structured interviews and usage-monitoring will collect preliminary evidence of efficacy, feasibility and acceptability, as

In recent years, agencies around the world have invested huge amounts of effort toward digitizing many aspects of the world's cultural heritage. Of particular importance is the digitization of outdoor archaeological sites. In the spirit of valorization of this digital information, many groups have developed virtual or augmented reality (AR) computer applications themed around a particular archaeological object. The problem of pose tracking in outdoor AR applications is addressed. Different positional systems are analyzed, resulting in the selection of a monocular camera-based user tracker. The limitations that challenge this technique from map generation, scale, anchoring, to lighting conditions are analyzed and systematically addressed. Finally, as a case study, our pose tracking system is implemented within an AR experience in the Byblos Roman theater in Lebanon.
A strategy is presented for reducing health risks at sites contaminated with buried transuranic (TRU) wastes by first taking measures to immobilize the contaminants until the second step, final action, becomes cost-effective and poses less risk to the remediation workers. The first step of this strategy does not preclude further action if it is warranted and is in harmony with environmental laws and regulations

In the present paper we consider application of overcomplete dictionaries to solution of general ill-posed linear inverse problems. Construction of an adaptive optimal solution for such problems usually relies either on a singular value decomposition or representation of the solution via an orthonormal basis. The shortcoming of both approaches lies in the fact that, in many situations, neither the eigenbasis of the linear operator nor a standard orthonormal basis constitutes an appropriate co...
Full Text Available Human action recognition based on 3D skeleton has become an active research field in recent years with the recently developed commodity depth sensors. Most published methods analyze an entire 3D depth data, construct mid-level part representations, or use trajectory descriptor of spatial-temporal interest point for recognizing human activities. Unlike previous work, a novel and simple action representation is proposed in this paper which models the action as a sequence of inconsecutive and discriminative skeleton poses, named as key skeleton poses. The pairwise relative positions of skeleton joints are used as feature of the skeleton poses which are mined with the aid of the latent support vector machine (latent SVM. The advantage of our method is resisting against intraclass variation such as noise and large nonlinear temporal deformation of human action. We evaluate the proposed approach on three benchmark action datasets captured by Kinect devices: MSR Action 3D dataset, UTKinect Action dataset, and Florence 3D Action dataset. The detailed experimental results demonstrate that the proposed approach achieves superior performance to the state-of-the-art skeleton-based action recognition methods.

The main activity of social robots is to interact with people. In order to do that, the robot must be able to understand what the user is saying or doing. Typically, this capability consists of pre-programmed behaviors or is acquired through controlled learning processes, which are executed before the social interaction begins. This paper presents a software architecture that enables a robot to learn poses in a similar way as people do. That is, hearing its teacher's explanations and acquiring new knowledge in real time. The architecture leans on two main components: an RGB-D (Red-, Green-, Blue- Depth) -based visual system, which gathers the user examples, and an Automatic Speech Recognition (ASR) system, which processes the speech describing those examples. The robot is able to naturally learn the poses the teacher is showing to it by maintaining a natural interaction with the teacher. We evaluate our system with 24 users who teach the robot a predetermined set of poses. The experimental results show that, with a few training examples, the system reaches high accuracy and robustness. This method shows how to combine data from the visual and auditory systems for the acquisition of new knowledge in a natural manner. Such a natural way of training enables robots to learn from users, even if they are not experts in robotics. PMID:24048336

Full Text Available Many researchers assume that people are creative, but their degree ofcreativity is different. The notion of creative thinking level has beendiscussed .by experts. The perspective of mathematics creative thinkingrefers to a combination of logical and divergent thinking which is basedon intuition but has a conscious aim. The divergent thinking is focusedon flexibility, fluency, and novelty in mathematical problem solving andproblem posing. As students have various backgrounds and differentabilities, they possess different potential in thinking patterns,imagination, fantasy and performance; therefore, students have differentlevels of creative thinking. A research study was conducted in order todevelop a framework for students’ levels of creative thinking inmathematics. This research used a qualitative approach to describe thecharacteristics of the levels of creative thinking. Task-based interviewswere conducted to collect data with ten 8thgrade junior secondary schoolstudents. The results distinguished five levels of creative thinking,namely level 0 to level 4 with different characteristics in each level.These differences are based on fluency, flexibility, and novelty inmathematical problem solving and problem posing.Keywords: student’s creative thinking, problem posing, flexibility,fluency, novelty DOI: http://dx.doi.org/10.22342/jme.1.1.794.17-40

Full Text Available The dynamics of the level of social functioning and quality of life of patients with schizophrenia as a marker of the effectiveness of psychoeducational programs. A comprehensive survey was carried out of 142 female patients at the age 18 – 35, which have diagnosis the schizophrenia in period of stabilization state. The integrative model of psychoeducational work was proposed, which includes application of various information modules, techniques of cognitive-behavioral therapy, training effects, problem-oriented discussions, and family psychotherapy. The psychoeducation was determined to be superior over conventional complex treatment intended for reduction of negative symptoms, productive symptoms and general psychopathological symptoms of patients with schizophrenia. It is supported by dynamic analysis of the clinical disturbances and psychopathological ones on the PANSS. The improvement of psychosocial functioning and quality of life of the patients with schizophrenia who participated in the psychoeducational activities was determined. It is proved that psychoeducation not only increases the amount of knowledge intensifies confidence in the fight against the disease, but solves the problem of social reintegration of the patient.

Many intervention studies lack an investigation and description of the factors that are relevant to its success or failure, despite its relevance to inform future interventions. This study aimed to explore the facilitators and barriers to the implementation of a psycho-educational intervention for care assistants caring for people with dementia in aged-care facilities. A process evaluation was carried out alongside a pretest/post-test controlled study conducted in aged-care facilities. Seven focus-group interviews involving 21 care assistants (female; mean age 43.37 ± 10.0) and individual semi-structured interviews with two managers (female; mean age 45.5 ± 10.26) were conducted 2 weeks and 6 months after the intervention, in two aged-care facilities. Interviews were recorded, transcribed and submitted to content analysis by two independent researchers. Results were organised into implementer, participant and organisation level hindered and facilitator factors. Findings enable the interpretation of the experimental results and underscore the importance of collecting the perception of different grades of staff to obtain information relevant to plan effective interventions. © 2016 Nordic College of Caring Science.

Family caregivers usually report the reduction of their life quality due to one of the family member's spinal cord injury. Thus, the present study aimed to investigate the effectiveness of psycho-educational interventions on the life quality of the family caregivers of the patients with spinal cord injury. The present randomized controlled trial was conducted on 72 family caregivers who had the primary responsibility of taking care of the patients with spinal cord injury. The participants were randomly divided into intervention (n=36) and control groups (n=36). The intervention group was involved in 90-minute educational sessions held once a week for four weeks. Both groups completed SF-36 questionnaire before and 2 and 6 weeks after the intervention. Then, the data were analyzed through independent t-test, Chi-square, and repeated measures ANOVA. All the caregivers had low quality of life and the lowest mean score was related to mental health in both groups. After the intervention, various dimensions of life quality had improved in the intervention group's caregivers compared to the control group (Peducational interventions on the life quality of the caregivers of the patients with spinal cord injury. According to the results, the authorities have to pay special attention to the problems of this group and educational interventions have to be continuously followed. IRCT2013070811388N2.

Lack of adequate training and support of primary caregivers of multiple sclerosis (MS) patients is the major factor in causing stress, anxiety, and increase of burden. Therefore, the treatment team members such as psychiatric nurses can help these vulnerable people overcome psychiatric pressures effectively not only through their care and referral role but also through their supportive characteristic, which helps the patients improve their clinical status, together with their social, familial, and work adaptation. Therefore, the researcher tried to identify the effect of a group psycho-education program on the burden family caregivers with MS patients. This is a two-group three-stage clinical trial. The researcher referred to the heads of neurology clinics to present the purpose of the study and to start the sampling. The neurology clinics of AL Zahra University Hospital, and also a Private Neurology Clinic were selected to collect the data of the study. The subjects were randomly selected, and then, assigned to two groups of study and control. Independent t-test showed a significant reduction in family caregivers' burden immediately after and 1-month after intervention in the study group, compared to control. Repeated measure ANOVA showed a significant reduction in caregivers' burden mean score in the study group (P family caregivers' burden, it is recommended to develop and design other programs for the family caregivers of the patients with MS.

There is no agreement about the measure to quantify the intellectual/developmental level in children with the dual disability of intellectual disability and autism. Therefore, we studied the psychometric properties and utility of Psycho-Educational Profile-Revised (PEP-R) as a developmental test in this population. We identified 116 children with dual disability from the day care and inpatient database of a specialised Autism Clinic. Scale and domain level scores of PEP-R were collected and analyzed. We examined the internal consistency, domain-total correlation of PEP-R and concurrent validity of PEP-R against Gesell's Developmental Schedule, inter-rater and test-retest reliability and utility of PEP-R among children with dual disability in different ages, functional level and severity of autism. Besides the adequate face and content validity, PEP-R demonstrates a good internal consistency (Cronbach's α ranging from 0.91 to 0.93) and domain-total correlation (ranging from 0.75 to 0.90). The inter-rater reliability (intraclass correlation coefficient, ICC = 0.96) and test-retest reliability (ICC = 0.87) for PEP-R is good. There is moderate-to-high concurrent validity with GDS (r ranging from 0.61 to 0.82; all Ps = 0.001). The utility of PEP-R as a developmental measure was good with infants, toddlers, pre-school and primary school children. The ability of PEP-R to measure the developmental age was good, irrespective of the severity of autism but was better with high-functioning children. The PEP-R as an intellectual/developmental test has strong psychometric properties in children with dual disability. It could be used in children with different age groups and severity of autism. PEP-R should be used with caution as a developmental test in children with dual disability who are low functioning.

In-depth knowledge of the in situ stress state at the Olkiluoto site is critical for stability assessment both prior to and after deposition of spent nuclear fuel in order to understand and avoid potential damage to the rock at the site. Posiva's Olkiluoto Spalling Experiment (POSE) was designed specifically for this purpose with three primary goals: establish the in situ spalling/damage strength of Olkiluoto migmatitic gneiss, establish the state of in situ stress at the -345 m depth level and act as a Prediction-Outcome (P-O) exercise. Phases 1 and 2 of POSE are outlined in WR 2012-60. The objectives of the third phase of the POSE experiment are the same as the original objectives outlined above. This report outlines the execution and results of the third phase of the POSE experiment. The third phase of the experiment involved internally heating the third experimental hole (ONK-EH3) of the POSE niche in order to cause a symmetrical thermal stress increase around the hole due to the thermal expansion of rock. This thermomechanically induced stress increase, coupled with the estimated existing in situ stress state, should cause the maximum principal stress around the hole to exceed the predicted spalling strength of the rock around the hole. ONK-EH3 is located almost completely in pegmatitic granite. Four fractures near the top of the hole were mapped after boring ONK-EH3, and a tensile failure located at the contact between mica-rich gneiss and pegmatitic granite was observed 18 months after boring, prior to the experiment. Based on predictive calculations and the estimated in situ state of stress, the maximum principal stress magnitude should reach ca. 100 MPa when the temperature was just below 100 deg C after 12 weeks of heating. There were problems with the heater control unit at the beginning of the experiment, after which heating proceeded according to plan. The crack damage threshold of pegmatitic granite has been determined to be 85 ±17 MPa at Olkiluoto

Background The Internet and other eHealth technologies offer a platform for improving the dissemination and accessibility of psychoeducational programs for youth with chronic illness. However, little is known about the recruitment process and yield of diverse samples in Internet research with youth who have a chronic illness. Objective The purpose of this study was to compare the demographic and clinical characteristics of youth with Type 1 diabetes on recruitment, participation, and satisfaction with 2 eHealth psychoeducational programs. Methods Youth with Type 1 diabetes from 4 sites in the United States were invited to participate (N=510) with 320 eligible youth consenting (mean age=12.3, SD 1.1; 55.3% female; 65.2% white; and mean A1C=8.3, SD 1.5). Data for this secondary analysis included demographic information (age, race/ethnicity, and income), depressive symptoms, and recruitment rates, including those who refused at point of contact (22.0%), passive refusers who consented but did not participate (15.3%), and those who enrolled (62.7%). Participation (80% lessons completed) and a satisfaction survey (ie, how helpful, enjoyable) were also analyzed. Chi-square or analysis of variance (ANOVA) analyses were used. Results There were significant differences in recruitment rates by income and race/ethnicity such that black, Hispanic, or mixed race/ethnicity and low-income youth were more likely to refuse passively compared to white and higher-income youth who were more likely to enroll (P<.001). Participation in program sessions was high, with 78.1% of youth completing at least 4 of 5 sessions. There were no significant differences in participation by program, age, gender, or race/ethnicity. Low-income youth were less likely to participate (P=.002). Satisfaction in both programs was also high (3.9 of 5). There were significant gender, race/ethnicity, and income differences, in that girls (P=.001), black, Hispanic, or mixed race/ethnicity youth (P=.02), and low
Full Text Available This paper improves the method of the traditional 5-point relative pose estimation algorithm, and proposes a relative pose estimation algorithm which is suitable for spherical panoramic images. The algorithm firstly computes the essential matrix, then decomposes the essential matrix to obtain the rotation matrix and the translation vector using SVD, and finally the reconstructed three-dimensional points are used to eliminate the error solution. The innovation of the algorithm lies the derivation of panorama epipolar formula and the use of the spherical distance from the point to the epipolar plane as the error term for the spherical panorama co-planarity function. The simulation experiment shows that when the random noise of the image feature points is within the range of pixel, the error of the three Euler angles is about 0.1°, and the error between the relative translational displacement and the simulated value is about 1.5°. The result of the experiment using the data obtained by the vehicle panorama camera and the POS shows that:the error of the roll angle and pitch angle can be within 0.2°, the error of the heading angle can be within 0.4°, and the error between the relative translational displacement and the POS can be within 2°. The result of our relative pose estimation algorithm is used to generate the spherical panoramic epipolar images, then we extract the key points between the spherical panoramic images and calculate the errors in the column direction. The result shows that the errors is less than 1 pixel.

This study examined the effectiveness, feasibility, and satisfaction with implementation of the FOCUS program in two US Cancer Support Community affiliates in Ohio and California as well as the cost to deliver the program. FOCUS is an evidence-based psychoeducational intervention for dyads (cancer patients and caregivers). A pre-post-intervention design was employed. Eleven, five-session Focus programs were delivered by licensed professionals in a small group format (three-four dyads/group) to 36 patient-caregiver dyads. An Implementation Training Manual, a FOCUS Intervention Protocol Manual, and weekly conference calls were used to foster implementation. Participants completed questionnaires prior to and following completion of each five-session FOCUS program to measure primary (emotional distress, quality of life) and secondary outcomes (benefits of illness, self-efficacy, and dyadic communication). Enrollment and retention rates and fidelity to FOCUS were used to measure feasibility. Cost estimates were based on time and median hourly wages. Repeated analysis of variance was used to analyze the effect of FOCUS on outcomes for dyads. Descriptive statistics were used to examine feasibility, satisfaction, and cost estimates. FOCUS had positive effects on QOL (p = .014), emotional (p = .012), and functional (p = .049) well-being, emotional distress (p = .002), benefits of illness (p = .013), and self-efficacy (p = .001). Intervention fidelity was 85% with enrollment and retention rates of 71.4 and 90%, respectively. Participants were highly satisfied. Cost for oversight and delivery of the five-session FOCUS program was $168.00 per dyad. FOCUS is an economic and effective intervention to decrease distress and improve the quality of life for dyads.

Cardiac pain arising from chronic stable angina (CSA) is a cardinal symptom of coronary artery disease and has a major negative impact on health-related quality of life (HRQL), including pain, poor general health status, and inability to self-manage. Current secondary prevention approaches lack adequate scope to address CSA as a multidimensional ischemic and persistent pain problem. This trial evaluated the impact of a low-cost six-week angina psychoeducation program, entitled The Chronic Angina Self-Management Program (CASMP), on HRQL, self-efficacy, and resourcefulness to self-manage anginal pain. One hundred thirty participants were randomized to the CASMP or three-month wait-list usual care; 117 completed the study. Measures were taken at baseline and three months. General HRQL was measured using the Medical Outcomes Study 36-Item Short Form and the disease-specific Seattle Angina Questionnaire (SAQ). Self-efficacy and resourcefulness were measured using the Self-Efficacy Scale and the Self-Control Schedule, respectively. The mean age of participants was 68 years, 80% were male. Analysis of variance of change scores yielded significant improvements in treatment group physical functioning [F=11.75(1,114), Phealth [F=10.94(1,114), P=0.001] aspects of generic HRQL. Angina frequency [F=5.57(1,115), P=0.02], angina stability [F=7.37(1,115), P=0.001], and self-efficacy to manage disease [F=8.45(1,115), P=0.004] were also significantly improved at three months. The CASMP did not impact resourcefulness. These data indicate that the CASMP was effective for improving physical functioning, general health, anginal pain symptoms, and self-efficacy to manage pain at three months and provide a basis for long-term evaluation of the program.

Bipolar disorder patients frequently present recurrent episodes and often experience subsyndromal symptoms, cognitive impairment and difficulties in functioning, with a low quality of life, illness relapses and recurrent hospitalization. Early diagnosis and appropriate intervention may play a role in preventing neuroprogression in this disorder. New technologies represent an opportunity to develop standardized psychological treatments using internet-based tools that overcome some of the limitations of face-to-face treatments, in that they are readily accessible and the timing of therapy can be tailored to user needs and availability. However, although many psychological programs are offered through the web and mobile devices for bipolar disorder, there is a lack of high quality evidence concerning their efficacy and effectiveness due to the great variability in measures and methodology used. This clinical trial is a simple-blind randomized trial within a European project to compare an internet-based intervention with treatment as usual. Bipolar disorder patients are to be included and randomly assigned to one of two groups: 1) the experimental group (tele-care support) and 2) the control group. Participants in both groups will be evaluated at baseline (pre-treatment) and post-treatment. This study describes the design of a clinical trial based on psychoeducation intervention that may have a significant impact on both prognosis and treatment in bipolar disorder. Specifically, bringing different services together (service aggregation), it is hoped that the approach proposed will significantly increase the impact of information and communication technologies on access and adherence to treatment, quality of the service, patient safety, patient and professional satisfaction, and quality of life of patients.

Full Text Available The Helping Families Programme is a psychoeducational parenting intervention that aims to improve outcomes and engagement for parents affected by clinically significant personality difficulties. This is achieved by working collaboratively with parents to explore ways in which their emotional and relational difficulties impact on parenting and child functioning, and to identify meaningful and realistic goals for change. The intervention is delivered via one-to-one sessions at weekly intervals over a period of 16 weeks. This protocol describes a two-arm parallel RCT in which consenting parents are randomly allocated in a 1:1 ratio to either the Helping Families Programme plus the usual services that the parent may be receiving from their mental health and/or social care providers, or to standard care (usual services plus a brief parenting advice session. The primary clinical outcome will be child behaviour. Secondary clinical outcomes will be child and parental mental health, parenting satisfaction, parenting behaviour and therapeutic alliance. Health economic measures will be collected on quality of life and service use. Outcome measures will be collected at the initial assessment stage, after the intervention is completed and at 6-month follow-up by research staff blind to group allocation. Trial feasibility will be assessed using rates of trial participation at the three time points and intervention uptake, attendance and retention. A parallel process evaluation will use qualitative interviews to ascertain key-workers’ and parent participants' experiences of intervention delivery and trial participation. The results of this feasibility study will determine the appropriateness of proceeding to a full-scale trial.

Among potential resources for people with serious mental illnesses (SMI) and their families, professionally delivered family psychoeducation (FPE) is designed to engage, inform, and educate family members, so that they can assist the person with SMI in managing their illness. In this article, we review research regarding FPE outcomes and implementation since 2001, updating the previous review in this journal (McFarlane, Dixon, Lukens, & Lucksted, Journal of Marital and Family Therapy 2003; 29, 223). Research on a range of FPE variations continues to return mostly positive effects for adults with schizophrenia and increasingly, bipolar disorder. More recent studies include functional outcomes as well as the more common relapse and hospitalization. FPE research involving adults with other diagnoses is increasing, as is FPE research outside the United States In both cases, uneven methodologies and multiple FPE variations make drawing conclusions difficult, although the core utility of access to information, skill building, problem solving, and social support often shines though. Since the previous review, several FPE programs for parents of children or youth with mood disorders have also been developed, with limited research showing more positive than null results. Similarly, we review the developing inquiry into early intervention and FPE, short-form FPE, and cost studies involving FPE. The second half of the article updates the paradox of FPE's evidence base versus its persistently low use, via recent implementation efforts. Multiple challenges and facilitating factors across healthcare systems and financing, individual programs and providers, family members, and consumers shape this issue, and we conclude with discussion of the need for empirical evaluation of implementation strategies and models. © 2011 American Association for Marriage and Family Therapy.

In low- and middle-income countries such as India, a feasible public health strategy could be to ensure continuous antipsychotics and psychoeducation for those with schizophrenia. Whether such a strategy favourably influences its course and outcome is not well-studied. The objectives of this study were to examine these issues in a cohort of patients with schizophrenia in a rural south Indian taluk (an administrative block). This cohort was part of a community intervention programme running in the place since the past one decade. A total of 201 patients were assessed after an average of four years of follow up. Psychopathology, disability and course of illness were assessed using Positive and Negative Syndrome Scale (PANSS), Indian Disability Evaluation and Assessment Scale (IDEAS) and Psychiatric and Personal History Schedule (PPHS), respectively. Interventions included ensuring continuous antipsychotic treatment and low-intensity psychoeducation. One hundred and forty two [70.6%; 95% confidence interval (CI): 64.35-76.95] of the 201 patients achieved clinical remission by the end of follow up period (four years); 140 (69.6%; 95% CI: 63.29-76.07) had satisfactory outcome (42.3% best outcome and 27.4% intermediate outcome). There was a significant reduction in the proportion of patients with disability [134/201 (66.7%) at baseline; 55/201 (27.3%) at follow up; PInterpretation & conclusions: Treatment with antipsychotics and psychoeducation can favourably influence the course of schizophrenia and reduce disability in a substantial proportion of patients. Structured psychosocial interventions may be indicated in the significant minority who show suboptimal outcome with this strategy.

Internet Gaming Disorder is an increasingly prevalent disorder, which can have severe consequences in affected young people and in their families. There is an urgent need to improve existing treatment programs; these are currently hampered by the lack of research in this area. It is necessary to more carefully define the symptomatic, psychosocial and personality characterization of these patients and the interaction between treatment and relevant variables. The objectives of this study were three: (1) to analyze the symptomatic and personality profiles of young patients with Internet Gaming Disorder in comparison with healthy controls; (2) to analyze the effectiveness of a cognitive behavioral treatment on reducing symptomatology; and (3) to compare the results of that treatment with or without the addition of a psychoeducational group offered to the parents. The final sample consisted of 30 patients consecutively admitted to a specialized mental health unit in Spain, and 30 healthy controls. The experimental group received individual cognitive-behavioral therapy. The experimental group was divided into two subgroups (N = 15), depending on the addition or not of a psychoeducational group for their parents (consecutively admitted). Scores on the Millon Adolescent Personality Inventory (MACI), the Symptom Checklist-Revised (SCL-90-R), the State-Trait Anxiety Index (STAI), and other clinical and psychopathological measures were recorded. The patients were re-assessed post treatment (except for the MACI questionnaire). Compared with healthy controls, patients did not differ in symptomatology at baseline, but scored significantly higher in the personality scales: Introversive and Inhibited, and in the expressed concerns scales: Identity Confusion, Self-Devaluation, and Peer Insecurity and scored significantly lower in the Histrionic and Egotistic scale. In the experimental group, pre-post changes differed statistically on SCL-90-R scales Hostility, Psychoticism, and

To synthesise evidence from UK-based randomised trials of psycho-educational interventions in children and young people (CYP) with Type 1 Diabetes (T1D) to inform the evidence-base for adoption of such interventions into the NHS. We searched Medline, Embase, Cochrane, PsycINFO, CINAHL, and Web of Science up to March 2016. Two reviewers independently selected UK-based randomised trials comparing psycho-educational interventions for improving management of T1D for CYP with a control group of usual care or attention control. The main outcome was glycaemic control measured by percentage of glycated haemoglobin (HbA1c); secondary outcomes included psychosocial functioning, diabetes knowledge, adverse and other clinical outcomes. A narrative synthesis and meta-analysis were conducted. Pooled effect sizes of standardised mean difference (SMD) were calculated. Ten eligible trials of three educational and seven psycho-educational interventions were identified. Most interventions were delivered by non-psychologists and targeted adolescents with more than one year duration of diabetes. Meta-analysis of nine of these trials (N = 1,838 participants) showed a non-significant reduction in HbA1c attributable to the intervention (pooled SMD = -0.06, 95% CI: -0.21 to 0.09). Psycho-educational interventions aiming to increase children's self-efficacy had a moderate, beneficial effect (SMD = 0.50, 95% CI: 0.13 to 0.87). No benefits on diabetes knowledge and other indicators of psychosocial functioning were identified. There is insufficient evidence to recommend the use of particular psycho-educational programme for CYP with T1D in the UK. Further trials with sufficient power and reporting standards are needed. Future trials could consider active involvement of psychological specialists in the delivery of psychologically informed interventions and implementation of psycho-educational interventions earlier in the course of the disease.

Recent guidelines for the diagnosis and treatment of attention deficit hyperactivity disorder (ADHD) have claimed the possible benefits of psychoeducational techniques in the comprehensive management of ADHD. To evaluate the efficacy of a psychoeducation programme for parents of children and adolescents with ADHD in a clinical setting using a blind randomized trial. 81 children/adolescents with ADHD were randomly assigned for their families to receive either a well-structured psychoeducation programme (intervention group, n = 44), or a parent counselling and support intervention (control group, n = 37). Measures of child ADHD symptoms, psychopathology, quality of life and family stress were taken before and after intervention and after a year follow-up. Parents and evaluators were unaware of the condition received. Compared to the support control group, the psychoeducation group showed ADHD Index and cognitive/inattention levels significantly reduced after the intervention ended (Mann-Whitney U = 3.34; p = 0.001; Mann-Whitney U = 3.47; p = 0.001). An improvement in the pro-social domain was also observed after 1 year follow-up (Mann-Whitney U = -2.37; p = 0.018), and clinical global impression found a statistically significant effect for severity over the time. Differences were initially found for the impact of the disorder in the family in different domains, including emotional and social functioning; these differences were no longer significant after alpha correction. No significant differences in quality of life or family stress were found in comparison with the control group. This psychoeducation programme is a valuable treatment for parents/carers of children/adolescents with ADHD, which needs to be considered when evaluating different non-pharmacological treatment options. Psychoeducation and other kind of non-pharmacological approaches need to be regarded not as a substitute, but as a complementary treatment to medications; these approaches might help other

Aims were to assess the efficacy of metacognitive training (MCT) in people with a recent onset of psychosis in terms of symptoms as a primary outcome and metacognitive variables as a secondary outcome. A multicenter, randomized, controlled clinical trial was performed. A total of 126 patients were randomized to an MCT or a psycho-educational intervention with cognitive-behavioral elements. The sample was composed of people with a recent onset of psychosis, recruited from nine public centers in Spain. The treatment consisted of eight weekly sessions for both groups. Patients were assessed at three time-points: baseline, post-treatment, and at 6 months follow-up. The evaluator was blinded to the condition of the patient. Symptoms were assessed with the PANSS and metacognition was assessed with a battery of questionnaires of cognitive biases and social cognition. Both MCT and psycho-educational groups had improved symptoms post-treatment and at follow-up, with greater improvements in the MCT group. The MCT group was superior to the psycho-educational group on the Beck Cognitive Insight Scale (BCIS) total (p = 0.026) and self-certainty (p = 0.035) and dependence self-subscale of irrational beliefs, comparing baseline and post-treatment. Moreover, comparing baseline and follow-up, the MCT group was better than the psycho-educational group in self-reflectiveness on the BCIS (p = 0.047), total BCIS (p = 0.045), and intolerance to frustration (p = 0.014). Jumping to Conclusions (JTC) improved more in the MCT group than the psycho-educational group (p = 0.021). Regarding the comparison within each group, Theory of Mind (ToM), Personalizing Bias, and other subscales of irrational beliefs improved in the MCT group but not the psycho-educational group (p tolerance to frustration. It seems that MCT could be useful to improve symptoms, ToM, and personalizing bias.
Full Text Available Active robot learners take an active role in their own learning by making queries to their human teachers when they receive new data. However, not every received input is useful for the robot, and asking for non-informative inputs or asking too many questions might worsen the user's perception of the robot. We present a novelty detection system that enables a robot to ask labels for new stimuli only when they seem both novel and interesting. Our system separates the decision process into two steps: first, it discriminates novel from known stimuli, and second, it estimates if these stimuli are likely to happen again. Our approach uses the notion of curiosity, which controls the eagerness with which the robot asks questions to the user. We evaluate our approach in the domain of pose learning by training our robot with a set of pointing poses able to detect up to 84%, 79%, and 78% of the observed novelties in three different experiments. Our approach enables robots to keep learning continuously, even after training is finished. The introduction of the curiosity parameter allows tuning, for the conditions in which the robot should want to learn more.
Full Text Available Effective interaction between a human and a robot requires the bidirectional perception and interpretation of actions and behavior. While actions can be identified as a directly observable activity, this might not be sufficient to deduce actions in a scene. For example, orienting our face toward a book might suggest the action toward “reading.” For a human observer, this deduction requires the direction of gaze, the object identified as a book and the intersection between gaze and book. With this in mind, we aim to estimate and map human visual attention as directed to a scene, and assess how this relates to the detection of objects and their related actions. In particular, we consider human head pose as measurement to infer the attention of a human engaged in a task and study which prior knowledge should be included in such a detection system. In a user study, we show the successful detection of attention to objects in a typical office task scenario (i.e., reading, working with a computer, studying an object. Our system requires a single external RGB camera for head pose measurements and a pre-recorded 3D point cloud of the environment.
Determination of relative three-dimensional (3D) position, orientation, and relative motion between two reference frames is an important problem in robotic guidance, manipulation, and assembly as well as in other fields such as photogrammetry.A solution to pose and motion estimation problem that uses two-dimensional (2D) intensity images from a single camera is desirable for real-time applications. The difficulty in performing this measurement is that the process of projecting 3D object features to 2D images is a nonlinear transformation. In this paper, the 3D transformation is modeled as a nonlinear stochastic system with the state estimation providing six degrees-of-freedom motion and position values, using line features in image plane as measuring inputs and dual quaternion to represent both rotation and translation in a unified notation. A filtering method called the Gaussian particle filter (GPF) based on the particle filtering concept is presented for 3D pose and motion estimation of a moving target from monocular image sequences. The method has been implemented with simulated data, and simulation results are provided along with comparisons to the extended Kalman filter (EKF) and the unscented Kalman filter (UKF) to show the relative advantages of the GPF. Simulation results showed that GPF is a superior alternative to EKF and UKF.

The continually increasing amount of orbital debris in near Earth space poses an increasing challenge to space situational awareness. Recent collisions of spacecraft caused abrupt increases in the density of both large and small debris in near Earth space. An especially challenging class of threats is that due to the increasing density of small (1 mm to 10 cm dimension) orbital debris. This small debris poses a serious threat since: (1) The high velocity enables even millimeter dimension debris to cause serious damage to vulnerable areas of space assets, e.g., detector windows; (2) The small size and large number of debris elements prevent adequate detection and cataloguing. We have identified solutions to this threat in the form of novel laser systems and novel ways of using these laser systems. While implementation of the solutions we identify is challenging we find approaches offering threat mitigation within time frames and at costs of practical interest. We base our analysis on the unique combination of coherent light specifically structured in both space and time and applied in novel ways entirely within the vacuum of space to deorbiting small debris. We compare and contrast laser based small debris removal strategies using ground based laser systems with strategies using space based laser systems. We find laser systems located and used entirely within space offer essential and decisive advantages over groundbased laser systems.
In this paper, we explore the use of a semi-supervised manifold alignment method for domain adaptation in the context of human body and head pose estimation in videos. We build upon an existing state-of-the-art system that leverages on external labelled datasets for the body and head features, and on the unlabelled test data with weak velocity labels to do a coupled estimation of the body and head pose. While this previous approach showed promising results, the learning of the underlying manifold structure of the features in the train and target data and the need to align them were not explored despite the fact that the pose features between two datasets may vary according to the scene, e.g. due to different camera point of view or perspective. In this paper, we propose to use a semi-supervised manifold alignment method to bring the train and target samples closer within the resulting embedded space. To this end, we consider an adaptation set from the target data and rely on (weak) labels, given for example by the velocity direction whenever they are reliable. These labels, along with the training labels are used to bias the manifold distance within each manifold and to establish correspondences for alignment.

Autonomous aerial refueling is a significant technology that can significantly extend the endurance of unmanned aerial vehicles. A reliable method that can accurately estimate the position and attitude of the probe relative to the drogue is the key to such a capability. A drogue pose estimation method based on infrared vision sensor is introduced with the general goal of yielding an accurate and reliable drogue state estimate. First, by employing direct least squares ellipse fitting and convex hull in OpenCV, a feature point matching and interference point elimination method is proposed. In addition, considering the conditions that some infrared LEDs are damaged or occluded, a missing point estimation method based on perspective transformation and affine transformation is designed. Finally, an accurate and robust pose estimation algorithm improved by the runner-root algorithm is proposed. The feasibility of the designed visual measurement system is demonstrated by flight test, and the results indicate that our proposed method enables precise and reliable pose estimation of the probe relative to the drogue, even in some poor conditions.

The ULTOR(Registered TradeMark) Passive Pose and Position Engine (P3E) technology, developed by Advanced Optical Systems, Inc (AOS), uses real-time image correlation to provide relative position and pose data for spacecraft guidance, navigation, and control. Potential data sources include a wide variety of sensors, including visible and infrared cameras. ULTOR(Registered TradeMark) P3E has been demonstrated on a number of host processing platforms. NASA is integrating ULTOR(Registerd TradeMark) P3E into its Relative Navigation System (RNS), which is being developed for the upcoming Hubble Space Telescope (HST) Servicing Mission 4 (SM4). During SM4 ULTOR(Registered TradeMark) P3E will perform realtime pose and position measurements during both the approach and departure phases of the mission. This paper describes the RNS implementation of ULTOR(Registered TradeMark) P3E, and presents results from NASA's hardware-in-the-loop simulation testing against the HST mockup.
Full Text Available Due to GPS restrictions, an inertial sensor is usually used to estimate the location of indoor mobile robots. However, it is difficult to achieve high-accuracy localization and control by inertial sensors alone. In this paper, a new method is proposed to estimate an indoor mobile robot pose with six degrees of freedom based on an improved 3D-Normal Distributions Transform algorithm (3D-NDT. First, point cloud data are captured by a Kinect sensor and segmented according to the distance to the robot. After the segmentation, the input point cloud data are processed by the Approximate Voxel Grid Filter algorithm in different sized voxel grids. Second, the initial registration and precise registration are performed respectively according to the distance to the sensor. The most distant point cloud data use the 3D-Normal Distributions Transform algorithm (3D-NDT with large-sized voxel grids for initial registration, based on the transformation matrix from the odometry method. The closest point cloud data use the 3D-NDT algorithm with small-sized voxel grids for precise registration. After the registrations above, a final transformation matrix is obtained and coordinated. Based on this transformation matrix, the pose estimation problem of the indoor mobile robot is solved. Test results show that this method can obtain accurate robot pose estimation and has better robustness.

In spite of our best efforts to secure the cyber world, the threats posed to personal privacy by attacks upon networks and software continue unabated. While there are many reasons for this state of affairs, clearly one of the reasons for continued vulnerabilities in software is the inability to assess their security properties and test their security systems while they are in development. A second reason for this growing threat to personal privacy is the growing sophistication and maliciousness of malware coupled with the increasing difficulty of detecting malware. The pervasive threat posed by malware coupled with the difficulties faced when trying to detect its presence or an attempted intrusion make addressing the malware threat one of the most pressing issues that must be solved in order to insure personal privacy to users of the internet. In this paper, we will discuss the threat posed by malware, the types of malware found in the wild (outside of computer laboratories), and current techniques that are available for from a successful malware penetration. The paper includes a discussion of anti-malware tools and suggestions for future anti-malware efforts.

The interrelationship between mathematics and science education has frequently been emphasized, and common goals and approaches have often been adopted between disciplines. Improving students' problem-solving skills in mathematics and science education has always been given special attention; however, the problem-posing approach which plays a key role in mathematics education has not been commonly utilized in science education. As a result, the purpose of this study was to better determine the effects of the problem-posing approach on students' problem-solving skills and metacognitive awareness in science education. This was a quasi-experimental based study conducted with 61 chemistry and 40 physics students; a problem-solving inventory and a metacognitive awareness inventory were administered to participants both as a pre-test and a post-test. During the 2017-2018 academic year, problem-solving activities based on the problem-posing approach were performed with the participating students during their senior year in various university chemistry and physics departments throughout the Republic of Turkey. The study results suggested that structured, semi-structured, and free problem-posing activities improve students' problem-solving skills and metacognitive awareness. These findings indicated not only the usefulness of integrating problem-posing activities into science education programs but also the need for further research into this question.

Assimilating multiple interactive elements simultaneously in working memory to allow understanding to occur, while solving an equation, would impose a high cognitive load. Element interactivity arises from the interaction between elements within and across operational and relational lines. Moreover, operating with special features (e.g. negative pronumeral) poses additional challenge to master equation solving skills. In an experiment, 41 8th grade students (girls = 16, boys = 25) sat for a pre-test, attended a session about equation solving, completed an acquisition phase which constituted the main intervention and were tested again in a post-test. The results showed that at post-test, students performed better on one-step equations tapping low rather than high element interactivity knowledge. In addition, students performed better on those one-step equations that contained no special features. Thus, both the degree of element interactivity and the operation with special features affect the challenge posed to 8th grade students on learning how to solve one-step equations.

This paper introduces a pose-sensing system for soft robot arms integrating a set of macrobend stretch sensors. The macrobend sensory design in this study consists of optical fibres and is based on the notion that bending an optical fibre modulates the intensity of the light transmitted through the fibre. This sensing method is capable of measuring bending, elongation and compression in soft continuum robots and is also applicable to wearable sensing technologies, e.g. pose sensing in the wrist joint of a human hand. In our arrangement, applied to a cylindrical soft robot arm, the optical fibres for macrobend sensing originate from the base, extend to the tip of the arm, and then loop back to the base. The connectors that link the fibres to the necessary opto-electronics are all placed at the base of the arm, resulting in a simplified overall design. The ability of this custom macrobend stretch sensor to flexibly adapt its configuration allows preserving the inherent softness and compliance of the robot which it is installed on. The macrobend sensing system is immune to electrical noise and magnetic fields, is safe (because no electricity is needed at the sensing site), and is suitable for modular implementation in multi-link soft continuum robotic arms. The measurable light outputs of the proposed stretch sensor vary due to bend-induced light attenuation (macrobend loss), which is a function of the fibre bend radius as well as the number of repeated turns. The experimental study conducted as part of this research revealed that the chosen bend radius has a far greater impact on the measured light intensity values than the number of turns (if greater than five). Taking into account that the bend radius is the only significantly influencing design parameter, the macrobend stretch sensors were developed to create a practical solution to the pose sensing in soft continuum robot arms. Henceforward, the proposed sensing design was benchmarked against an electromagnetic

Computer-aided drug design has become an integral part of drug discovery and development in the pharmaceutical and biotechnology industry, and is nowadays extensively used in the lead identification and lead optimization phases. The drug design data resource (D3R) organizes challenges against blinded experimental data to prospectively test computational methodologies as an opportunity for improved methods and algorithms to emerge. We participated in Grand Challenge 2 to predict the crystallographic poses of 36 Farnesoid X Receptor (FXR)-bound ligands and the relative binding affinities for two designated subsets of 18 and 15 FXR-bound ligands. Here, we present our methodology for pose and affinity predictions and its evaluation after the release of the experimental data. For predicting the crystallographic poses, we used docking and physics-based pose prediction methods guided by the binding poses of native ligands. For FXR ligands with known chemotypes in the PDB, we accurately predicted their binding modes, while for those with unknown chemotypes the predictions were more challenging. Our group ranked #1st (based on the median RMSD) out of 46 groups, which submitted complete entries for the binding pose prediction challenge. For the relative binding affinity prediction challenge, we performed free energy perturbation (FEP) calculations coupled with molecular dynamics (MD) simulations. FEP/MD calculations displayed a high success rate in identifying compounds with better or worse binding affinity than the reference (parent) compound. Our studies suggest that when ligands with chemical precedent are available in the literature, binding pose predictions using docking and physics-based methods are reliable; however, predictions are challenging for ligands with completely unknown chemotypes. We also show that FEP/MD calculations hold predictive value and can nowadays be used in a high throughput mode in a lead optimization project provided that crystal structures of

In this paper we shall be concerned with Lavientiev regularization method to reconstruct solutions x 0 of non ill-posed problems F(x)=y o , where instead of y 0 noisy data y δ is an element of X with absolut(y δ -y 0 ) ≤ δ are given and F:X→X is an accretive nonlinear operator from a real reflexive Banach space X into itself. In this regularization method solutions x α δ are obtained by solving the singularly perturbed nonlinear operator equation F(x)+α(x-x*)=y δ with some initial guess x*. Assuming certain conditions concerning the operator F and the smoothness of the element x*-x 0 we derive stability estimates which show that the accuracy of the regularized solutions is order optimal provided that the regularization parameter α has been chosen properly.

The most innovative point of this paper is the parameterization of the motion model of the Extended Kalman Filter.

Full Text Available New psychoactive substances (NPS are defined as substances of abuse, either in a pure form or a preparation, that are not controlled by the 1961 Single Convention on Narcotic Drugs or the 1971 Convention on Psychotropic Substances, but which may pose a public health threat. In this context, the term “new” does not necessarily refer to new inventions but to substances that have recently become available or popular in a given society or country. This definition indicates that the problem of NPS is not new; however, the availability of any information via new communication technologies in the 21st century has enabled the spread of unwanted and socially harmful information, like information on the commercial availability of various NPS, offered in rising amounts and brands.

Ornamental horticulture has been identified as an important threat to plant biodiversity and is a major pathway for plant invasions worldwide. In this context, the family Cactaceae is particularly challenging because it is considered the fifth most threatened large taxonomic group in the world; several species are among the most widespread and damaging invasive species; and Cactaceae is one of the most popular horticultural plant groups. Based on the Convention on International Trade in Endangered Species of Wild Flora and Fauna and the 11 largest online auction sites selling cacti, we documented the international cactus trade. To provide an in-depth look at the dynamics of the industry, we surveyed the businesses involved in the cactus trade in South Africa (a hotspot of cactus trade and invasions). We purchased seeds of every available species and used DNA barcoding to identify species to the genus level. Although <20% of this trade involved threatened species and <3% involved known invasive species, many species were identified by a common name. However, only 0.02% of the globally traded cacti were collected from wild populations. Despite a large commercial network, all South African imports (of which 15% and 1.5% were of species listed as threatened and invasive, respectively) came from the same source. With DNA barcoding, we identified 24% of the species to genus level. Based on our results, we believe that if trade restrictions are placed on the small proportion of cacti that are invasive and there is no major increase in harvesting of native populations, then the commercial trade in cactus poses a negligible environmental threat. However, there are currently no effective methods for easily identifying which cacti are traded, and both the illicit harvesting of cacti from the wild and the informal trade in invasive taxa pose on-going conservation challenges. © 2017 Society for Conservation Biology.

The high number of involuntary placements of people with mental disorders in Switzerland and other European countries constitutes a major public health issue. In view of the ethical and personal relevance of compulsory admission for the patients concerned and given the far-reaching effects in terms of health care costs, innovative interventions to improve the current situation are much needed. A number of promising approaches to prevent involuntary placements have been proposed that target continuity of care by increasing self-management skills of patients. However, the effectiveness of such interventions in terms of more robust criteria (e.g., admission rates) has not been sufficiently analysed in larger study samples. The current study aims to evaluate an intervention programme for patients at high risk of compulsory admission to psychiatric hospitals.

In-situ intelligent manufacturing for large-volume equipment requires industrial robots with absolute high-accuracy positioning and orientation steering control. Conventional robots mainly employ an offline calibration technology to identify and compensate key robotic parameters. However, the dynamic and static parameters of a robot change nonlinearly. It is not possible to acquire a robot's actual parameters and control the absolute pose of the robot with a high accuracy within a large workspace by offline calibration in real-time. This study proposes a real-time online absolute pose steering control method for an industrial robot based on six degrees of freedom laser tracking measurement, which adopts comprehensive compensation and correction of differential movement variables. First, the pose steering control system and robot kinematics error model are constructed, and then the pose error compensation mechanism and algorithm are introduced in detail. By accurately achieving the position and orientation of the robot end-tool, mapping the computed Jacobian matrix of the joint variable and correcting the joint variable, the real-time online absolute pose compensation for an industrial robot is accurately implemented in simulations and experimental tests. The average positioning error is 0.048 mm and orientation accuracy is better than 0.01 deg. The results demonstrate that the proposed method is feasible, and the online absolute accuracy of a robot is sufficiently enhanced.

This paper proposes a new approach to find the regularization parameter for linear least-squares discrete ill-posed problems. In the proposed approach, an artificial perturbation matrix with a bounded norm is forced into the discrete ill-posed model matrix. This perturbation is introduced to enhance the singular-value (SV) structure of the matrix and hence to provide a better solution. The proposed approach is derived to select the regularization parameter in a way that minimizes the mean-squared error (MSE) of the estimator. Numerical results demonstrate that the proposed approach outperforms a set of benchmark methods in most cases when applied to different scenarios of discrete ill-posed problems. Jointly, the proposed approach enjoys the lowest run-time and offers the highest level of robustness amongst all the tested methods.

Background This study explored the effectiveness of family psycho-education in reducing patients’ symptoms and on family caregiver burden. Methods Seventy Iranian outpatients with a diagnosis of schizophrenia disorder and their caregivers were randomly allocated to the experimental (n = 35) or control groups (n = 35). Patients in the experimental group received antipsychotic drug treatment and a psycho-educational program was arranged for their caregivers. The psycho-educational program consisted of ten 90-min sessions held during five weeks (two session in each week). Each caregiver attended 10 sessions (in five weeks) At baseline, immediately after intervention, and one month later. Validated tools were used to assess patients’ clinical status and caregiver burden. Results Compared with the control group, the case group showed significantly reduced symptom severity and caregiver burden both immediately after intervention and one month later. Conclusions These results suggest that even need based short-term psycho-educational intervention for family members of Iranian patients with schizophrenic disorder may improve the outcomes of patients and their families.

Family psycho-education is one of the most effective interventions for preventing relapse in patients with schizophrenia. We evaluated the efficacy of a needs-assessment-based educational program in comparison with a current program (textbook based) in the treatment of schizophrenia. Patients with schizophrenia and their families (N = 60) were allocated to needs-assessment-based education (treatment) and textbook-based (control) programs; both included 10 sessions of education within about 6 months. Symptoms were assessed by the Positive and Negative Syndrome Scale (PANSS) prior to intervention and every 3 months for a total of 18 months. A 25% decrease or increase in total PANSS score was considered as response or relapse, respectively. Forty-two cases completed the study. The total PANSS score was significantly decreased in both groups with more reduction in the treatment group. Positive and negative scale scores were reduced in the treatment group, but not significantly in the control group. Response rate was higher in the treatment group and relapse rate was lower (15% vs. 27.2%, P = 0.279). In logistic regression analysis, needs-assessment-based psycho-education was associated with more treatment response. Needs-assessment-based psycho-education is more effective than textbook-based education for treating schizophrenia. We recommend psychiatric care centers to conduct needs-assessment and develop their own program for family psycho-education.

Chronic illness of a child puts healthy children of the family at risk of distress. Previous studies have demonstrated that healthy children's psychological symptoms can be reduced when the child knows more about the disease. So far, there is limited evidence of the effectiveness of psychoeducational interventions for healthy children. To compare the effectiveness of an inpatient family-oriented rehabilitation program with vs without additional psychoeducational sessions for healthy children of families with children with cancer. We performed a controlled study in 4 German family-oriented rehabilitation clinics. The outcomes of n = 73 healthy children (mean age: M = 9.55; SD = 3.14; range: 4-18), who participated in 5 additional psychoeducational sessions, were compared with the outcomes of n = 111 healthy children (mean age: M = 8.85; SD = 3.28; range: 4-17), who underwent the usual inpatient rehabilitation program. Primary outcomes were the healthy children's cancer-specific knowledge and their emotional symptoms. Secondary outcomes were family satisfaction and quality of life. Intention-to-treat analyses showed that both groups improved significantly from preintervention to postintervention. Improvements comprised knowledge about cancer (F(1,174) = 11.03, p child with cancer. Additional psycho-educational sessions did not show any substantial additional improvement.

This paper proposes a model for assessing the risk posed by natural hazards to infrastructures, with a focus on the indirect losses and loss of stability for the population relying on the infrastructure. The model prescribes a three-level analysis with increasing level of detail, moving from qualitative to quantitative analysis. The focus is on a methodology for semi-quantitative analyses to be performed at the second level. The purpose of this type of analysis is to perform a screening of the scenarios of natural hazards threatening the infrastructures, identifying the most critical scenarios and investigating the need for further analyses (third level). The proposed semi-quantitative methodology considers the frequency of the natural hazard, different aspects of vulnerability, including the physical vulnerability of the infrastructure itself, and the societal dependency on the infrastructure. An indicator-based approach is applied, ranking the indicators on a relative scale according to pre-defined ranking criteria. The proposed indicators, which characterise conditions that influence the probability of an infrastructure malfunctioning caused by a natural event, are defined as (1) robustness and buffer capacity, (2) level of protection, (3) quality/level of maintenance and renewal, (4) adaptability and quality of operational procedures and (5) transparency/complexity/degree of coupling. Further indicators describe conditions influencing the socio-economic consequences of the infrastructure malfunctioning, such as (1) redundancy and/or substitution, (2) cascading effects and dependencies, (3) preparedness and (4) early warning, emergency response and measures. The aggregated risk estimate is a combination of the semi-quantitative vulnerability indicators, as well as quantitative estimates of the frequency of the natural hazard, the potential duration of the infrastructure malfunctioning (e.g. depending on the required restoration effort) and the number of users of

The lionfish, Pterosis volitans, a native of Indo-Pacific oceans, is a popular saltwater aquarium fish despite venomous spines on its fins. Lionfish were inadvertently introduced into the western Atlantic from Florida in the early 1990s and have overpopulated and dispersed widely into the Caribbean Sea and Gulf of Mexico. Initiatives to control lionfish populations were launched, including the National Oceanographic and Atmospheric Administration (NOAA)-sponsored "Lionfish as Food Campaign".2 Recently, scientists from the Food and Drug Administration (FDA) reported that lionfish caught off the US Virgin Islands contained ciguatoxins and could cause ciguatera fish poisoning (CFP); a seafood-borne poisoning without an antidote or any specific treatment, and a potential for prolonged neurotoxicity. Lionfish pose several public health threats. New strategies to control the lionfish population explosion in coastal waters and offshore fisheries are needed now to ensure seafood safety and public health. The lionfish, Pterosis volitans, is native to the reefs of the western Indian and Pacific Oceans (Figure 1). Brightly colored with red, white, and black stripes and adorned with feathery fins, the lionfish is a popular saltwater aquarium fish despite venomous spines on its fins (Figure 2). Lionfish were introduced into the western North Atlantic from Florida in the early 1990s after some specimens were discarded by dissatisfied amateur aquarists and others escaped from hurricane-flooded public aquariums.1 Since lionfish are voracious carnivores, have few natural predators, and reproduce prolifically, they have overpopulated and dispersed widely from Cape Hatteras to Florida, throughout the Caribbean Sea, and into the Gulf of Mexico.1 The population density of lionfish in its new, invaded territory now exceeds that of its native habitat.1 As a result, campaigns to control lionfish populations were launched in Florida and the Caribbean. Lionfish now pose several public

This study introduces an approach to model-based 3D pose estimation and instantaneous motion analysis of the human hand-forearm limb in the application context of safe human-robot interaction. 3D pose estimation is performed using two approaches: The Multiocular Contracting Curve Density (MOCCD) algorithm is a top-down technique based on pixel statistics around a contour model projected into the images from several cameras. The Iterative Closest Point (ICP) algorithm is a bottom-up approach which uses a motion-attributed 3D point cloud to estimate the object pose. Due to their orthogonal properties, a fusion of these algorithms is shown to be favorable. The fusion is performed by a weighted combination of the extracted pose parameters in an iterative manner. The analysis of object motion is based on the pose estimation result and the motion-attributed 3D points belonging to the hand-forearm limb using an extended constraint-line approach which does not rely on any temporal filtering. A further refinement is obtained using the Shape Flow algorithm, a temporal extension of the MOCCD approach, which estimates the temporal pose derivative based on the current and the two preceding images, corresponding to temporal filtering with a short response time of two or at most three frames. Combining the results of the two motion estimation stages provides information about the instantaneous motion properties of the object. Experimental investigations are performed on real-world image sequences displaying several test persons performing different working actions typically occurring in an industrial production scenario. In all example scenes, the background is cluttered, and the test persons wear various kinds of clothes. For evaluation, independently obtained ground truth data are used.

The inherent noise associated with odometry manifests itself as errors in localization for autonomous vehicles. Visual odometry has been previously used in order to supplement classical vehicle odometry. However, visual odometry is limited in its ability to reduce errors in localization for large travel distances that entail the cumulative summing of individual frame-to-frame image errors. In this paper, a novel machine vision approach for tiled surfaces is proposed to address this problem. Tile edges in a laboratory environment are used to define a travel trajectory for the Quansar Qbot (autonomous vehicle) built on the iRobot iRoomba platform with a forward facing camera. Tile intersections are used to enable asynchronous error recovery for vehicle position and orientation. The proposed approach employs real-time image classification and is feasible for error mitigation for large travel distances. The average position error for an 8m travel distance using classical odometry was measured to be 0.28m. However, implementation of the proposed approach resulted in an error of 0.028m. The proposed approach therefore significantly reduces pose estimation error and could be used to supplement existing modalities such as GPS and Laser-based range sensors

Full Text Available There are many activities and numerous objects in this universe, which make them interesting for photographers to explore as their masterpiece. One of the things that has been enjoyed and is always developing over time is the use of human as an object, whether as a candid photography or as a posing model in accordance to photographer's concept and theme. Using human being as an object is always popular among beginners and professional photographers. Even nowadays people often hold photo shoot as a media in many social network sites. And so if they understand the simple theories in basic knowledge of using human object, the results will be maximized, and of course, much more interesting. The more a photographer does his job, the better his experience is, and his work will develop. Thus, it makes him more alert to the situation and character of a model, which will then become more observant in predicting their outcome in photography.

Fear of childbirth is a common reason for seeking cesarean section. It is important to consider outcomes and costs associated with alternative treatment and delivery mode. We compared well-being and costs of group psychoeducation and conventional care for fear of childbirth. Randomized controlled trial. A total of 371 nulliparous women scoring over the 95th centile in the Wijma Delivery Expectancy Questionnaire (W-DEQ) during the first trimester. Finland, data from obstetrical patient records and questionnaires. Randomization to group psychoeducation with relaxation (six sessions during pregnancy, one after childbirth, n = 131), or surveillance and referral on demand (n = 240). All costs in maternity care during pregnancy, delivery and postnatally according to Diagnoses Related Groups. Life satisfaction and general well-being 3 months after childbirth (by a Satisfaction with Life Scale and Well-being Visual Analogue Scale). The groups did not differ in total direct costs (€3786/woman in psychoeducative group and €3830/woman in control group), nor in life satisfaction or general well-being. Although only 76 (30%) of the women assigned to the surveillance were referred to special maternity care and 36 (15%) attended advanced prenatal classes, costs in the psychoeducation group did not exceed the costs of the controls, mostly because of the greater number of uncomplicated vaginal deliveries (63% vs. 47%, p = 0.005). Through an association with safer childbirth and equal well-being after delivery, psychoeducative group treatment for nulliparous women with fear of childbirth can be a recommended choice for the same overall costs as conventional treatment. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

Nursing is a dynamic and supportive job, with the main role of taking care of patients. Maintaining appropriate communication of the nurse with the patients is particularly known as the main core of care in mental health. However, in spite of the importance of providing communication, one of the main sources of stress in nurses of psychiatry wards is communication with the patients. Some important reasons for inappropriate relationship between the nurse and patient can be lack of necessary skills to communicate with patients because of insufficient training. Although training communication skills is an important part of the education of medical and paramedical students, in recent studies it has been demonstrated that the communication skills learned in theoretical courses would not necessarily be transferred to clinical settings, and proving training in clinical settings is a must. The present study was carried out to determine the effect of training communication skills using psychoeducation method on the stress level of nurses of psychiatry wards in 2010. This is a quasi-experimental study. The participants were 45 nurses; 23 and 22 in the experiment and control groups, respectively, working in psychiatry wards of Noor and Farabi hospitals, Isfahan, Iran. The sampling was carried out by the census method, and then the participants were randomly assigned to the two groups of experiment and control, using random number table. The two groups filled out the demographic data form and also the questionnaire on nurses' occupational stress, designed by the researcher. The questionnaire was filled out three times; before, immediately after, and one month after the training. Training of communication skills was carried out using group psychoeducation method, in six sessions, each lasted for 1.5 hours. The training sessions of the experiment group were held in Farabi Hospital. The findings indicated that before the intervention, the members of the two groups had a high

Purpose: The association between radiotherapy for gynecological carcinoma and sexual dysfunction is well established. Regular vaginal dilation is widely recommended to these women as a way for them to maintain vaginal health and good sexual functioning. However, the compliance rate with this recommendation is low. The purpose of this study was to test the effectiveness of a group psychoeducational program based on the 'information-motivation-behavioral skills' model of behavior change in increasing the rate of compliance. Methods and Materials: Thirty-two women with Stage I or II cervical or endometrial carcinoma who were being treated with radiotherapy were randomized and received either the experimental group program or the control intervention that consisted of written information and brief counseling. Outcome measures included global sexual health, knowledge about sexuality and cancer, fears about sexuality after cancer, and vaginal dilation compliance. Results: Younger women attending the experimental program (44.4%) were significantly more likely to follow recommendations for vaginal dilation than those who received the control intervention (5.6%). Women, regardless of age, who received the experimental intervention reported less fear about sex after cancer treatment. The older women who received the experimental intervention gained more sexual knowledge. There was no evidence that the experimental intervention improved global sexual health. Conclusions: This is the first controlled study to provide evidence of an intervention's effectiveness 1. in increasing women's vaginal dilation following radiotherapy for gynecological carcinoma and 2. in reducing their fears about sex after cancer. Most women, particularly younger women, are unlikely to follow the recommendation to dilate unless they are given assistance in overcoming their fears and taught behavioral skills

Booster sessions as a means of maintaining the benefits of psycho-educational programs have received little attention in caregiving research. Caregivers were offered a booster session following participation in a program entitled Learning to Become a Family Caregiver (LBFC) intended to facilitate transition to the caregiver role after diagnostic disclosure of dementia in a relative. The 90-minute booster session served to review program content and afforded the opportunity to discuss and practice learned skills. This study sought to test the efficacy of the booster session in maintaining or recovering program effects at six months post-program. Participants in the program were randomly assigned to a group that received the booster session (n = 31) or a group that did not (n = 29). A third control group was also formed, which continued to receive only the usual care provided in memory clinics. Eligible participants - French-speaking primary caregivers of a relative diagnosed with Alzheimer's in the past nine months - were recruited in memory clinics in Quebec (Canada). Participants were blindly assessed before randomization and six months after the booster session on outcomes associated with a healthy role transition. Prediction analyses revealed one significant positive effect of the booster session: emergence of preparedness to provide care. Moreover, with or without the booster session, the program continued to have a positive effect on psychological distress and contributed to the emergence of self-efficacy in dealing with caregiving situations. The booster session had no significant effect on knowledge of services, planning for future care needs, use of reframing as a coping strategy, perceived informal support, and family conflicts. The limited effect observed is discussed in terms of the booster session's content and intensity. Recommendations are made for designing future research on the effect of booster sessions, including the importance of including a

The objectives of the third phase of the POSE experiment are to determine the in situ state of stress at Olkiluoto and the spalling strength of Olkiluoto rock, by internal heating of the experimental hole (ONK-EH3) using 8 vertically installed heaters. This report presents the results from the Acoustic and ultrasonic monitoring carried out around the third experimental hole of the POSE niche between November 2012 and May 2013. The experiment was monitored using an array of 24 transducers installed along 4 monitoring drillholes and data was automatically acquired and processed using the system installed at the niche by Applied Seismology Consultants in May 2012. Daily ultrasonic surveys were carried out between 14 th November 2012 and 21 st May 2013, monitoring the changes in transmission velocities of P and S-waves with an estimated error of ±2 m x s -1 (ASC, 2013). Changes in transmission velocities closely follow the evolution of the temperature profile in the hole wall. An increase in both P-and S-wave transmission velocities is observed at all depth levels and surveyed raypaths during the heating phase, with the highest changes observed in raypaths skimming the hole surface and depths between 2.33 m and 3.7 m. This observation indicates the closure of in situ and excavation-induced microcracks due to thermal stress. After the heaters were switched off, P-wave velocities show a marked decrease, in all raypaths reaching values below those measured at the start of the monitoring approximately 4 weeks after the heaters were switched off. The highest decrease was observed along raypaths surveying the region skimming the hole wall. This decrease below original background values indicates the induction of rock degradation as microcracking induced through the heating-cooling cycle. Changes in P- and S-wave transmission velocity were used to calculate changes in Young's modulus and Poisson's ratio along the different raypaths and depth levels. An overall

Among the multitude of crises that US research institutions may face are those caused by animal rights activists. While most activists opposed to animal research use peaceful and lawful means of expressing their opinions, some extremists resort to illegal methods. Arson, break-ins, and theft with significant property damage at US animal research facilities began in the 1980s. The most troubling trend to develop in the past decade is the targeting of individuals associated with animal research, whether directly or indirectly, and the use of violent scare tactics to intimidate researchers and their families. The National Association for Biomedical Research has a 30-year history of monitoring the animal rights movement and assisting member institutions with crisis situations. In this article we discuss attacks on researchers at their homes, cyber crimes, exploitation of new media formats, infiltration of research facilities, and the targeting of external research stakeholders and business partners. We describe the need for a well-conceived crisis management plan and strong leadership to mitigate crisis situations. Institutions with well-informed leaders and crisis management teams ready to take timely action are best equipped to protect staff, laboratory animals, and research programs. They act on early warnings, provide support for targeted staff, seek legal remedies, thoughtfully control access to research facilities, and identify and enlist new research supporters. We underscore the importance of up-to-date crisis planning so that institutions are not only aware of ongoing risks posed by animal rights extremists but also better prepared to take preemptive action and able to manage those risks successfully.

Hot and cold climates have posed differential threats to human survival throughout history. Cold temperatures can pose direct threats to survival in themselves, whereas hot temperatures may pose threats indirectly through higher prevalence of infectious disease. These differential threats yield convergent predictions for the relationship between more demanding climates and freedom of expression, but divergent predictions for freedom from discrimination.

Indigenous interpretations of mental illness might negatively impact treatment adherence. However, psychiatric "labeling" potentially leads to stigma among Chinese groups, thus encouraging the use of indigenous idioms. We examined how relatives' use of indigenous labeling varied with the consumers' experience of illness and whether indigenous labeling protected relatives from internalized and experienced forms of stigma. Forty-nine relatives of Chinese-immigrant consumers with psychosis were sampled. Although consumers had progressed to the middle stages of psychosis, 39% of relatives used indigenous idioms to label psychosis. Indigenous labeling decreased when illness duration increased and when visual hallucinations were present. Indigenous labeling further predicted lower internalized stigma among relatives. Relatives who used indigenous labeling also reported fewer indirect stigma experiences, although not after controlling for illness severity. The frequency of direct discrimination among relatives did not differ by labeling. These forms of felt stigma might be embedded into relatives' psychoeducation programs to mitigate adverse consequences of psychiatric labeling.

Full Text Available The article begins with a reflection on performative utterances, which are speech acts, to show that the right contributes to the creation of reality and subjectivity. Based on this argument examines five definitions of the situation of children demobilized from illegal armed groups in Colombia, named according to their effects psychoeducational: victimizing, pathologizing, criminalizing, idealizing and responsabilizing. Each definition is examined in terms of their philosophical affiliation, deterministic, nondeterministic or interactionist, its effects on the construction of the identity of minors and in his appeal to responsibility and legal insanity. At the end of the article shows the intervention proposals arising from each of the definitions and shows the role that restorative justice can play in building a model of care which confers responsibility to the children demobilized from illegal armed groups, and other victims of armed conflict, which guarantees the restitution of rights and also empowers them as key actors in redefining their social role and identity reconstruction.

Enhancing immediate and contingent responding by caregivers to children’s signals is an important strategy to support social interactions between caregivers and their children with autism. Yet, there has been limited examination of parents’ responsive behaviour in association with children’s social behaviour post caregiver-mediated intervention. Eighty-five dyads were randomized to one of two 10-week caregiver-training interventions. Parent–child play interactions were coded for parental responsivity and children’s joint engagement. Significant gains in responsivity and time jointly engaged were found post JASPER parent-mediated intervention over a psychoeducation intervention. Further, combining higher levels of responsive behaviour with greater adoption of intervention strategies was associated with greater time jointly engaged. Findings encourage a focus on enhancing responsive behaviour in parent-mediated intervention models. PMID:26797940

This study explores the efficacy of BEfree, a 12-session group intervention that integrates psychoeducation, mindfulness, compassion and value-based action, in a sample of overweight and obese women with binge eating disorder ( N = 31). We used repeated measures analyses of variance and explored processes of change in binge eating and eating psychopathology. At post-intervention, participants decreased in binge eating severity, eating psychopathology, external shame, self-criticism, psychological inflexibility, body image cognitive fusion and increased self-compassion and engagement with valued actions. These results were maintained at 3- and 6-month follow-up. The changes in binge eating were mediated by the changes in the psychological processes promoted by BEfree.

Bipolar disorder (BD) is a chronic and disabling psychiatric disorder characterized by recurrent episodes of mania/hypomania and depression. Dialectical behavior therapy (DBT) techniques have been shown to effectively treat borderline personality disorder, a condition also marked by prominent affective disturbances. The utility of DBT techniques in treating BD has been largely unexplored. The purpose of this research was to conduct a pilot study of a DBT-based psychoeducational group (BDG) in treating euthymic, depressed, or hypomanic Bipolar I or II patients. In this experiment, 26 adults with bipolar I or II were randomized to intervention or wait-list control groups and completed the Beck depression inventory II, mindfulness-based self-efficacy scale, and affective control scale at baseline and 12 weeks. The BDG intervention consisted of 12 weekly 90-min sessions which taught DBT skills, mindfulness techniques, and general BD psychoeducation. Using RM-ANOVA, subjects in BDG demonstrated a trend toward reduced depressive symptoms, and significant improvement in several MSES subscales indicating greater mindful awareness, and less fear toward and more control of emotional states (ACS). These findings were supported with a larger sample of patients who completed the BDG. Furthermore, group attendees had reduced emergency room visits and mental health related admissions in the six months following BDG. The small sample size in RCT affects power to detect between group differences. How well improvements after the12-week BDG were maintained is unknown. There is preliminary evidence that DBT skills reduce depressive symptoms, improve affective control, and improve mindfulness self-efficacy in BD. Its application warrants further evaluation in larger studies. Copyright © 2012 Elsevier B.V. All rights reserved.

Determining the pose of a moving camera is an important task in computer vision. In this paper, we derive a projective Newton algorithm on the manifold to refine the pose estimate of a camera. The main idea is to benefit from the fact that the 3-D rigid motion is described by the special Euclidean group, which is a Riemannian manifold. The latter is equipped with a tangent space defined by the corresponding Lie algebra. This enables us to compute the optimization direction, i.e., the gradient and the Hessian, at each iteration of the projective Newton scheme on the tangent space of the manifold. Then, the motion is updated by projecting back the variables on the manifold itself. We also derive another version of the algorithm that employs homeomorphic parameterization to the special Euclidean group. We test the algorithm on several simulated and real image data sets. Compared with the standard Newton minimization scheme, we are now able to obtain the full numerical formula of the Hessian with a 60% decrease in computational complexity. Compared with Levenberg-Marquardt, the results obtained are more accurate while having a rather similar complexity.

This thesis highlights a problem-posing approach to science education. By this is meant an approach that explicitly aims at providing students with content-related motives for extending their existing conceptual resources, experiential base and belief system in a certain direction, such that a further development in that direction eventually leads to a proper understanding of science. An elaboration of that approach consists in designing, testing, improving, etc, concrete didactical structures. The eventual aim of the approach is a coherent, and by means of developmental research empirically supported, didactical structure that covers the whole of science education. The thesis also contains a few steps in the direction suggested by this programmatic view. It contains an illustration of the heuristic value of an articulation of a didactical structure in some main substructures, based on the work of van Hiele and ten Voorde. It further contains a discussion of some methodological aspects relating to the design and evaluation of a didactical structure, and of the role that a further developed version of Davidson's theory of interpretation could play in this respect. A detailed didactical structure of the topic of radioactivity is presented, evaluated and, on the basis of the evaluation, judged as `good enough.' Also the role of the teacher in a problem-posing approach is dis-cussed, and in particular the consequences for that role of giving students control over and responsibility for the progress of their learning process with respect to content.

The aim of this study was to evaluate the effect of psychoeducation on return to work as an adjunct to standard case management in individuals on sick leave at risk of having a mental disorder. The participants could have different diagnoses but were all at risk of having a mental disorder. Between 2012 and 2014, 430 participants on sick leave were randomly allocated to either an intervention or control group. The psychoeducation consisted of 2-h sessions once a week for 6 weeks. The sessions focused on stress and work life and was based on problem-solving techniques and coping strategies. The main outcome, the relative risk (RR) of a full return to work based on register data from the job centres, was determined during the first 3 and 6 months after participation in the psychoeducation programme. At baseline and at 3 and 6 months after the intervention, the participants received a questionnaire on psychological symptoms, mental health-related quality of life, and locus of control. During the first 6 months after inclusion, the two groups had almost the same RR of a full return to work (RR:0.97, 95% CI: 0.78;1.21), but during the first 3 months, the individuals in the intervention group had a significantly higher risk of not having fully returned to work (RR:0.68, 95% CI:0.47;0.98). The individuals in the intervention group who had participated in at least four of the six psychoeducational sessions returned to work considerably slower at both time points than did the control group. The intervention did not decrease the level of psychological symptoms or improve mental health-related quality of life; however, individuals in the intervention group improved their scores on internal locus of control at both 3 and 6 months. Offering psychoeducation to individuals on sick leave at risk of having a mental disorder had no influence on the chance of a full return to work during the first 6 months; however, it did result in a higher relative risk of not returning to work

Mental disorders are a major public health problem and are debilitating in many nations throughout the world. Many individuals either do not or are not able to access treatment. The Internet can be a medium to convey to the community accessible evidenced-based interventions to reduce these burdens. The objective of this study is to investigate the effectiveness of 4 weeks of a Web-based psychoeducational intervention program for depressive and anxiety symptoms in the community of Selangor, Malaysia. A two-arm randomized controlled trial of a single-blind study will be conducted to meet the objective of this study. We aim to recruit 84 participants each for the intervention and control groups. The recruitment will be from participants who participated in the first phase of this research. The primary outcomes of this study are depressive and anxiety scores, which will be assessed using the Patient Health Questionnaire 9 and Generalized Anxiety Disorder 7, respectively. The secondary outcome includes mental health literacy of the participants, which will be assessed using the self-developed and adapted Mental Health Literacy Questionnaire. The psychoeducational intervention program consists of four sessions, which will be accessed each week. The depressive and anxiety symptoms will be compared between participants who participated in the psychoeducational program compared with the control group. Depressive and anxiety scores and mental health literacy will be assessed at week 1 and at follow-ups at week 5 and week 12, respectively. The psychoeducational intervention program consists of four sessions, which will be accessed at each week. The depressive and anxiety symptoms will be compared between the intervention and control groups using a series of mixed ANOVAs. Depressive and anxiety scores and mental health literacy will be assessed at week 1 and at two follow-ups at week 5 and week 12, respectively. To our knowledge, this study will be the first randomized

Parents with cancer have high rates of psychological morbidity, and their children are at risk of poor psychosocial outcomes, particularly in the context of parental distress and poor family communication. Parents express concerns about the impact of cancer on their children and report a lack of professional guidance in meeting their children's needs. Few parenting interventions exist and current interventions have extensive infrastructure demands making them unsuitable for routine use in most health settings. The aims of this study are to develop and establish the feasibility and acceptability of a novel and accessible psycho-educational intervention to improve parenting efficacy and decrease parental stress among adults with cancer who have children aged 3-12 years. The intervention will be suitable for parents with cancer who are receiving treatment with a view to longer term survival, irrespective of cancer diagnosis, and their respective co-parents. This study comprises two phases using the UK Medical Research Council framework for developing complex interventions. In the development phase, intervention content will be iteratively developed and evaluated in consultation with consumers, and in the piloting phase, feasibility will be tested in a clinical sample of 20 parents with cancer and their co-parents using a single arm, pre-test post-test design. The intervention will comprise an audiovisual resource (DVD), a question prompt list, and a telephone call with a clinical psychologist. Questionnaires administered pre- and 1 month post-intervention will assess parental stress, psychological morbidity, quality of life, self-efficacy and perceptions of child adjustment, and family functioning. Intervention feasibility will be determined by mixed-method participant evaluation of perceived usefulness, benefits, and acceptability. This new initiative will translate existing descriptive evidence into an accessible intervention that supports parenting during cancer

A finite element CFD algorithm is developed for Euler and Navier-Stokes aerodynamic applications. For the linear basis, the resultant approximation is at least second-order-accurate in time and space for synergistic use of three procedures: (1) a Taylor weak statement, which provides for derivation of companion conservation law systems with embedded dispersion-error control mechanisms; (2) a stiffly stable second-order-accurate implicit Rosenbrock-Runge-Kutta temporal algorithm; and (3) a matrix tensor product factorization that permits efficient numerical linear algebra handling of the terminal large-matrix statement. Thorough analyses are presented regarding well-posed boundary conditions for inviscid and viscous flow specifications. Numerical solutions are generated and compared for critical evaluation of quasi-one- and two-dimensional Euler and Navier-Stokes benchmark test problems.

The late-life developmental process of self-transcendence shapes elders' perspectives on self, others, the nature of this world, and of a dimension beyond the here and now. This qualitative pilot study evaluated the Psychoeducational Approach to Transcendence and Health (PATH) Program, a psychoeducational intervention to promote self-transcendence and well-being in community-dwelling women at a senior center. The intervention involved eight weekly group sessions using group processes, mindfulness practices, creative experiences, and independent at-home practice. The findings supported the underlying theory-based structure and content of the intervention and indicated the intervention may empower elders to attend to self-care, develop acceptance, and learn new skills associated with health and well-being, thus merits further study. Based on insights gained from facilitators' and participants' experiences and perceptions, the intervention will be revised and strengthened. © The Author(s) 2015.

People with a major neurocognitive disorder (PwND) are found to have a lower health related quality of life (HRQoL) than those without neurocognitive disorder. This research study aims to evaluate the effectiveness of a psycho-education group in improving the HRQoL of Chinese PwND. By adopting randomized control trial (RCT), Chinese PwND were randomly assigned to either a 10-session psycho-education group or the control group. Family caregivers of treatment group were encouraged to take part in two sessions focusing on the caring and communication skills. Control group and their family caregivers received standardized educational materials on basic information on neurocognitive disorder for them to read at home. Standardized assessment was conducted both with PwND and their caregivers independently to give the self-rated and caregiver-rated HRQoL of PwND in the pre- and post- treatment periods by a research assistant who was blind to the group assignment of the participants. Moreover, qualitative interviews were also conducted for ten participants and five family caregivers of the treatment group to identify those group elements relating to its effectiveness. 2 × 2 repeated measures ANCOVA demonstrated that the treatment group (n = 32) was significantly more effective than the control group (n = 32) in improving the caregiver-rated HRQoL (F[1, 61] = 4.35, p = .04 psycho-education group significantly improves caregiver-rated HRQoL of PwND, supporting the feasibility and effectiveness of the psycho-education group.

The rate of caesarean section continues to increase, and there is evidence that childbirth fear is a contributing factor. Insufficient evidence is available on the impact of reducing childbirth fear on health-related quality of life and health service use. We undertook an economic evaluation of a psycho-education counselling intervention offered by midwives to address women's fear of childbirth in Australia. Pregnant women (n = 339) with high childbirth fear were randomised to a midwife-led psycho-education intervention for childbirth fear or to usual care. This paper presents the economic evaluation of the intervention based on health-related quality of life and health service use from recruitment to six weeks postpartum (n = 184). The changes in health-related quality of life after birth (EQ-5D-3L: 0.016 vs. 0.010, p = 0.833, for usual care and intervention) and total health care use cost (AUS$10,110 vs. AUS$9980, p = 0.819) were similar between groups. The intervention did not increase costs; however, in a post hoc analysis, the interventions might be cost-effective for those women with very high childbirth fear. This brief psycho-education intervention by midwives did not improve the health-related quality of life of women, and had no impact on overall cost. Copyright © 2016 Elsevier B.V.

Limited data exists on psychological interventions for adolescent depression in African countries such as Nigeria. This study therefore investigates the effects of a psychological intervention that includes psycho-education and basic elements of cognitive behavioural therapy (CBT) on depressed medication-treated adolescents in Nigeria. This was a pre-post one-group intervention study of 18 adolescents aged 13-18 years with clinically diagnosed depressive disorder, attending a specialist psychiatric hospital. They had been on antidepressants for 3 months or longer. Depressive symptoms, knowledge of depression, hope, and attitudes towards treatment adherence were measured at baseline and repeated at 1 and 4 weeks post-intervention. The adolescents received four sessions of a group-based manualised intervention focused on psycho-education and basic CBT strategies. Statistically significant reductions in depressive symptoms were recorded, as were improvements in the adolescents' knowledge of depression, hope, and attitude towards treatment adherence one week after the intervention (all p = 0.001). All differences were sustained at 4 weeks post-intervention. Participants' satisfaction with the intervention was high. This study suggests that adding psycho-education with elements of CBT to antidepressant treatment is feasible, acceptable and can produce further benefits to depressed adolescents in this region.

Full Text Available Abstract Background Universal interventions to prevent postnatal mental disorders in women have had limited success, perhaps because they were insufficiently theorised, not gender-informed and overlooked relevant risk factors. This study aimed to determine whether an innovative brief psycho-educational program for mothers, fathers and first newborns, which addressed salient learning needs about infant behaviour management and adjustment tasks in the intimate partner relationship, prevented postpartum mental health problems in primiparous women. Methods A before and after controlled study was conducted in primary care in seven local government areas in Victoria, Australia. English-speaking couples with one-week old infants were invited consecutively to participate by the maternal and child health nurse at the universal first home visit. Two groups were recruited and followed sequentially: both completed telephone interviews at four weeks and six months postpartum and received standard health care. Intervention group participants were also invited to attend a half-day program with up to five couples and one month old infants, facilitated by trained, supervised nurses. The main outcome was any Composite International Diagnostic Interview (CIDI diagnosis of Depression or Anxiety or Adjustment Disorder with Depressed Mood, Anxiety, or Mixed Anxiety and Depressed Mood in the first six months postpartum. Factors associated with the outcome were established by logistic regression controlling for potential confounders and analysis was by intention to treat. Results In total 399/646 (62% women were recruited; 210 received only standard care and 189 were also offered the intervention; 364 (91% were retained at follow up six months postpartum.

Previous studies on the treatment of women with fear of childbirth have focused on the delivery mode. Women with fear of childbirth often suffer from anxiety and/or depression, and treatment therefore also needs to target postnatal psychological well-being and the early mother-infant relationship. Three hundred and seventy-one nulliparous women out of 4575 scored ≥100 in prospective screening (Wijma Delivery Expectancy Questionnaire, W-DEQ-A), indicating severe fear of childbirth. These women were randomised to psychoeducative group intervention with relaxation (n = 131; six sessions during pregnancy, one postnatal) or to conventional care (n = 240) by community nurses (referral if necessary). Psycho-emotional and psychosocial evaluations [Edinburgh Postnatal Depression Scale (EPDS), social support, Maternal Adjustment and Attitudes (MAMA), Traumatic Events Scale (TES) and the Wijma Delivery Experience Questionnaire (W-DEQ-B)] were completed twice during pregnancy and/or 3 months postpartum. Postnatal maternal adjustment (MAMA mean score 38.1 ± 4.3 versus 35.7 ± 5.0, p = 0.001) and childbirth experience (mean W-DEQ-B sum score 63.0 ± 29 versus 73.7 ± 32, p = 0.008) were better in the intervention group compared with controls. In hierarchical regression, social support, participating in intervention, and less fearful childbirth experience predicted better maternal adjustment. The level of postnatal depressive symptoms was significantly lower in the intervention group (mean sum score 6.4 ± 5.4 versus 8.0 ± 5.9 p = 0.04). There were no differences in the frequency of post-traumatic stress symptoms between the groups. In nulliparous women with severe fear of childbirth, participation in a targeted psychoeducative group resulted in better maternal adjustment, a less fearful childbirth experience and fewer postnatal depressive symptoms, compared with conventional care.

Exercise may have both a preventive and a therapeutic impact on mental health problems. The Exercise without Worries intervention aims to reduce stress and depressive symptoms in low-SES women by means of a group-based program combining physical exercise and psycho-education. Between September 2005 and May 2008, 161 Dutch low-SES women with elevated stress or depressive symptom levels were randomly assigned to the combined exercise/psycho-education intervention (EP), exercise only (E) or a waiting list control condition (WLC). The E condition provided low to moderate intensity stretching, strength, flexibility, and body focused training as well as relaxation, while the EP program integrated the exercise with cognitive-behavioral techniques. Depressive symptoms (CES-D) and perceived stress (PSS) were measured before and immediately after the intervention and at 2, 6 and 12 month follow-up. Multilevel linear mixed-effects models revealed no differential patterns in reduction of CES-D or PSS scores between the EP, E and WLC groups on the short (post-test and 2 month follow-up) or long term (6 and 12 months follow-up). Depressive symptom outcomes were moderated by initial depressive symptom scores: women from the EP and E groups with fewer initial symptoms benefited from participation on the short term. Further, women in the EP and E groups with the lowest educational level reported more stress reduction at post-test than women with higher educational levels. In the overall target population of low-SES women, no indications were found that the Exercise without Worries course reduced depressive symptom and stress levels on the short or long term. The findings do suggest, however, that exercise alone or in combination with psycho-education may be a viable prevention option for certain groups of disadvantaged women. Especially those low-SES women with less severe initial problems or those with low educational attainment should be targeted for future depression prevention

Full Text Available Robust real-time hand detection and tracking in video sequences would enable many applications in areas as diverse ashuman-computer interaction, robotics, security and surveillance, and sign language-based systems. In this paper, we introducea new approach for detecting human hands that works on single, cluttered, low-resolution images. Our prototype system, whichis primarily intended for security applications in which the images are noisy and low-resolution, is able to detect hands as smallas 2424 pixels in cluttered scenes. The system uses grayscale appearance information to classify image sub-windows as eithercontaining or not containing a human hand very rapidly at the cost of a high false positive rate. To improve on the false positiverate of the main classifier without affecting its detection rate, we introduce a post-processor system that utilizes the geometricproperties of skin color blobs. When we test our detector on a test image set containing 106 hands, 92 of those hands aredetected (86.8% detection rate, with an average false positive rate of 1.19 false positive detections per image. The rapiddetection speed, the high detection rate of 86.8%, and the low false positive rate together ensure that our system is useable asthe main detector in a diverse variety of applications requiring robust hand detection and tracking in low-resolution, clutteredscenes.

When xenotropic murine leukemia virus-related virus (XMRV) was first reported in association with chronic fatigue syndrome, it was suggested that it might offer a risk to blood safety. Thus, the prevalence of the virus among blood donors and, if present, its transmissibility by transfusion need to be defined. Two populations of routine blood donor samples (1435 and 13,399) were obtained for prevalence evaluations; samples from a linked donor-recipient repository were also evaluated. Samples were tested for the presence of antibodies to XMRV-related recombinant antigens and/or for XMRV RNA, using validated, high-throughput systems. The presence of antibodies to XMRV could not be confirmed among a total of 17,249 blood donors or recipients (0%; 95% confidence interval [CI], 0%-0.017%); 1763 tested samples were nonreactive for XMRV RNA (0%; 95% CI, 0%-0.17%). Evidence of infection was absent from 109 recipients and 830 evaluable blood samples tested after transfusion of a total of 3741 blood components. XMRV and related murine leukemia virus (MLV) markers are not present among a large population of blood donors and evidence of transfusion transmission could not be detected. Thus, these viruses do not currently pose a threat to blood recipient safety and further actions relating to XMRV and MLV are not justified. © 2012 American Association of Blood Banks.

The gripper finger design is a recurring problem in many robotic grasping platforms used in industry. The task of switching the gripper configuration to accommodate a new batch of objects typically requires engineering expertise and is a lengthy and costly iterative trial-and-error process. One...... in a sample industrial object grasping scenario for a finger that was designed using an automated simulation-based geometry optimization method (Wolniakowski et al., 2013, 2015). We test the developed gripper with a set of grasps subjected to structured perturbation in a simulation environment and in the real......-world setting. We provide a comparison of the data obtained by using both of these approaches. We argue that the strong correspondence observed in results validates the use of dynamic simulation for the gripper finger design and optimization....

Full Text Available Human activity recognition (HAR is essential for understanding people’s habits and behaviors, providing an important data source for precise marketing and research in psychology and sociology. Different approaches have been proposed and applied to HAR. Data segmentation using a sliding window is a basic step during the HAR procedure, wherein the window length directly affects recognition performance. However, the window length is generally randomly selected without systematic study. In this study, we examined the impact of window length on smartphone sensor-based human motion and pose pattern recognition. With data collected from smartphone sensors, we tested a range of window lengths on five popular machine-learning methods: decision tree, support vector machine, K-nearest neighbor, Gaussian naïve Bayesian, and adaptive boosting. From the results, we provide recommendations for choosing the appropriate window length. Results corroborate that the influence of window length on the recognition of motion modes is significant but largely limited to pose pattern recognition. For motion mode recognition, a window length between 2.5–3.5 s can provide an optimal tradeoff between recognition performance and speed. Adaptive boosting outperformed the other methods. For pose pattern recognition, 0.5 s was enough to obtain a satisfactory result. In addition, all of the tested methods performed well.

Background Psychoeducational family intervention (PFI) has been proven to be effective in improving the levels of family burden and patients’ personal functioning in schizophrenia and bipolar disorders (BDs). Less is known about the impact of PFI on relatives’ coping strategies in BD. Methods A multicenter, controlled, outpatient trial funded by the Italian Ministry of Health and coordinated by the Department of Psychiatry of the University of Campania “Luigi Vanvitelli” has been conducted in patients with bipolar I disorder (BD-I) and their key relatives consecutively recruited in 11 randomly selected Italian community mental health centers. We aim to test the hypothesis that PFI improves problem-oriented coping strategies in relatives of BD-I patients compared to the Treatment As Usual (TAU) group. Results The final sample was constituted of 123 patients and 139 relatives. At baseline assessment (T0), the vast majority of relatives already adopted problem-oriented coping strategies more frequently than the emotion-focused ones. At the end of the intervention, relatives receiving PFI reported a higher endorsement of adaptive coping strategies, such as “maintenance of social interests” (odds ratio [OR]=0.309, CI=0.04–0.57; p=0.023), “positive communication with the patient” (OR=0.295, CI=0.13–0.46; p=0.001), and “searching for information” (OR=0.443, CI=0.12–0.76; p=0.007), compared to TAU relatives, after controlling for several confounders. As regards the emotion-focused coping strategies, relatives receiving the experimental intervention less frequently reported to adopt “resignation” (OR=−0.380, CI=−0.68 to −0.08; p=0.014) and “coercion” (OR=−0.268, CI=−0.46 to −0.08; p=0.006) strategies, compared to TAU relatives. Conclusion PFI is effective in improving the adaptive coping strategies of relatives of BD-I patients, but further studies are needed for evaluating the long-term benefits of this intervention. PMID

The aim of our study was to evaluate the effectiveness of a self-information booklet (SIB) in decreasing anxiety and panic attacks in Panic Disorder (PD) patients. Eighty-four patients attending an outpatient clinic due to panic disorder were randomly chosen to receive paroxetine with/without a friendly-designed brochure. Follow-up was done by a masked rater after 1, 3,and 12 weeks in order to evaluate whether the co-administration of paroxetine and the brochure (Group A) had a beneficial effect over the administration of paroxetine alone (Group B). After 3 weeks of therapy, Group A patients had significantly greater improvement and lower scores on the Hamilton Anxiety Scale, the Panic Self Questionnaire, and the Visual Analog Scale. After 12 weeks, the differential improvement was not statistically significant and both groups had improved as compared to baseline. The administration of a psychoeducational brochure (SIB) to PD patients at the initiation of therapy had beneficial effects during the first weeks of treatment. Although this effect fades away, the role of the SIB is overstressed in its ability to increase well being and compliance, and reduce anxiety and panic attacks. Copyright 2002 Wiley-Liss, Inc.

There is great demand for effective management of children with Autistic Spectrum Disorders (ASD). This study aimed to investigate the effect of an individually tailored psycho-educational program for autistic children on the scores of the Childhood Autism Rating Scale (CARS) and the Short Sensory Profile (SSP). Forty children (36 males) were enrolled into an intervention program which consisted of occupational therapy including sensory integration techniques, speech therapy, social skills therapy and parent-directed approaches. Autism severity was assessed using CARS; sensory response capability with the SSP pre- and post-treatment. Eight children were intellectually normal; 12 borderline and 20 of low intelligence. Pre-treatment CARS showed that 8 were mildly autistic, 32 moderately-severely autistic. Post-treatment, 24 children changed category; 11 were no longer autistic. The percentage of children performing in the definitive difference region, according to total SSP score, changed slightly (45% vs 32.5%). Comparison of the pre- and post-treatment values revealed that CARS decreased significantly (p values (p educational therapy had a significant effect on autism severity according to CARS. Changes in the SSP scores were not significant. Copyright © 2011 European Paediatric Neurology Society. Published by Elsevier Ltd. All rights reserved.

The aim of this research, which represents an additional and longer follow-up to a previous trial, was to evaluate a 5-year follow-up study of a combined treatment (pharmacological+psychoeducational and cognitive-behavioral therapy) as compared with a standard pharmacological treatment in patients with refractory bipolar disorder. Forty patients were randomly assigned to either an Experimental group-under combined treatment - or a Control group - under pharmacological treatment. Data were analyzed by analysis of variance (ANOVA), with repeated measures at different evaluation time points. Between-group differences were significant at all evaluation time points after treatment. Experimental group had less hospitalization events than Control group in the 12-month evaluation (P=0.015). The Experimental group showed lower depression and anxiety in the 6-month (P=0.006; P=0.019), 12-month (P=0.001; Ptherapy is long-term effective for patients with refractory bipolar disorder.

Full Text Available Molecular docking remains an important tool for structure-based screening to find new ligands and chemical probes. As docking ambitions grow to include new scoring function terms, and to address ever more targets, the reliability and extendability of the orientation sampling, and the throughput of the method, become pressing. Here we explore sampling techniques that eliminate stochastic behavior in DOCK3.6, allowing us to optimize the method for regularly variable sampling of orientations. This also enabled a focused effort to optimize the code for efficiency, with a three-fold increase in the speed of the program. This, in turn, facilitated extensive testing of the method on the 102 targets, 22,805 ligands and 1,411,214 decoys of the Directory of Useful Decoys-Enhanced (DUD-E benchmarking set, at multiple levels of sampling. Encouragingly, we observe that as sampling increases from 50 to 500 to 2000 to 5000 to 20,000 molecular orientations in the binding site (and so from about 1×10(10 to 4×10(10 to 1×10(11 to 2×10(11 to 5×10(11 mean atoms scored per target, since multiple conformations are sampled per orientation, the enrichment of ligands over decoys monotonically increases for most DUD-E targets. Meanwhile, including internal electrostatics in the evaluation ligand conformational energies, and restricting aromatic hydroxyls to low energy rotamers, further improved enrichment values. Several of the strategies used here to improve the efficiency of the code are broadly applicable in the field.

Subspace-based face representation can be looked as a regression problem. From this viewpoint, we first revisited the problem of recognizing faces across pose differences, which is a bottleneck in face recognition. Then, we propose a new approach for cross-pose face recognition using a regressor with a coupled bias-variance tradeoff. We found that striking a coupled balance between bias and variance in regression for different poses could improve the regressor-based cross-pose face representation, i.e., the regressor can be more stable against a pose difference. With the basic idea, ridge regression and lasso regression are explored. Experimental results on CMU PIE, the FERET, and the Multi-PIE face databases show that the proposed bias-variance tradeoff can achieve considerable reinforcement in recognition performance.
Full Text Available In order to obtain high precision path tracking for a dual-arm space robot, a trajectory planning method with pose feedback is proposed to be introduced into the design process in this paper. Firstly, pose error kinematic models are derived from the related kinematics and desired pose command for the end-effector and the base, respectively. On this basis, trajectory planning with pose feedback is proposed from a control perspective. Theoretical analyses show that the proposed trajectory planning algorithm can guarantee that pose error converges to zero exponentially for both the end-effector and the base when the robot is out of singular configuration. Compared with the existing algorithms, the proposed algorithm can lead to higher precision path tracking for the end-effector. Furthermore, the algorithm renders the system good anti-interference property for the base. Simulation results demonstrate the effectiveness of the proposed trajectory planning algorithm.

In this paper, we propose an electric appliance control support system for aged and bedridden people using pose recognition. We proposed a pose recognition system that distinguishes between seven poses of the user on the bed. First, the face and arm regions of the user are detected by using the skin color. Our system focuses a recognition region surrounding the face region. Next, the higher order local autocorrelation features within the region are extracted. The linear discriminant analysis creates the coefficient matrix that can optimally distinguish among training data from the seven poses. Our algorithm can recognize the seven poses even if the subject wears different clothes and slightly shifts or slants on the bed. From the experimental results, our system achieved an accuracy rate of over 99 %. Then, we show that it possibles to construct one of a user-friendly system.

Mobile robots, operating in unconstrained indoor and outdoor environments, would benefit in many ways from perception of the human awareness around them. Knowledge of people's head pose and gaze directions would enable the robot to deduce which people are aware of the its presence, and to predict future motions of the people for better path planning. To make such inferences, requires estimating head pose on facial images that are combination of multiple varying factors, such as identity, appearance, head pose, and illumination. By applying multilinear algebra, the algebra of higher-order tensors, we can separate these factors and estimate head pose regardless of subject's identity or image conditions. Furthermore, we can automatically handle uncertainty in the size of the face and its location. We demonstrate a pipeline of on-the-move detection of pedestrians with a robot stereo vision system, segmentation of the head, and head pose estimation in cluttered urban street scenes.

Environmental pollution by anti-influenza drugs is increasingly recognized as a threat to aquatic environments. However, little is known about empirical data on risk effects posed by environmentally relevant concentrations of anti-influenza drug based on recently published ecotoxicological researches in Taiwan. Here we linked ecotoxicology models with an epidemiological scheme to assess exposure risks of aquatic organisms and environmental hazards posed by antiviral oseltamivir (Tamiflu) use in Taiwan. Built on published bioassays, we used probabilistic risk assessment model to estimate potential threats of environmentally relevant hazards on algae, daphnid, and zerbrafish. We found that Tamiflu use was unlikely to pose a significant chronic environmental risk to daphnia and zebrafish during seasonal influenza. However, the chronic environmental risk posed by Tamiflu use during pandemic was alarming. We conclude that no significant risk to algal growth was found during seasonal influenza and high pandemic Tamiflu use. -- Highlights: • Environmentally relevant concentrations of anti-influenza drug have ecotoxicologically important effects. • Tamiflu is unlikely to pose a significant chronic environmental risk during seasonal influenza. • Chronic environmental risk posed by Tamiflu during pandemic is alarming. • Tertiary process in sewage treatment plants is crucial in mitigating Tamiflu exposure risk. -- A probabilistic framework can be used for assessing exposure risks posed by environmentally relevant concentrations of anti-influenza drug in aquatic ecosystems

This paper presents an attribute and-or grammar (A-AOG) model for jointly inferring human body pose and human attributes in a parse graph with attributes augmented to nodes in the hierarchical representation. In contrast to other popular methods in the current literature that train separate classifiers for poses and individual attributes, our method explicitly represents the decomposition and articulation of body parts, and account for the correlations between poses and attributes. The A-AOG model is an amalgamation of three traditional grammar formulations: (i)Phrase structure grammar representing the hierarchical decomposition of the human body from whole to parts; (ii)Dependency grammar modeling the geometric articulation by a kinematic graph of the body pose; and (iii)Attribute grammar accounting for the compatibility relations between different parts in the hierarchy so that their appearances follow a consistent style. The parse graph outputs human detection, pose estimation, and attribute prediction simultaneously, which are intuitive and interpretable. We conduct experiments on two tasks on two datasets, and experimental results demonstrate the advantage of joint modeling in comparison with computing poses and attributes independently. Furthermore, our model obtains better performance over existing methods for both pose estimation and attribute prediction tasks.

Estimating three-dimensional (3D) human poses from a single camera is usually implemented by searching pose candidates with image descriptors. Existing methods usually suppose that the mapping from feature space to pose space is linear, but in fact, their mapping relationship is highly nonlinear, which heavily degrades the performance of 3D pose estimation. We propose a method to recover 3D pose from a silhouette image. It is based on the multiview feature embedding (MFE) and the locality-sensitive autoencoders (LSAEs). On the one hand, we first depict the manifold regularized sparse low-rank approximation for MFE and then the input image is characterized by a fused feature descriptor. On the other hand, both the fused feature and its corresponding 3D pose are separately encoded by LSAEs. A two-layer back-propagation neural network is trained by parameter fine-tuning and then used to map the encoded 2D features to encoded 3D poses. Our LSAE ensures a good preservation of the local topology of data points. Experimental results demonstrate the effectiveness of our proposed method.

This paper proposes a unique approach for head pose estimation of subjects with eyeglasses by using a combination of line detection and classification approaches. Head pose estimation is considered as an important non-verbal form of communication and could also be used in the area of Human-Computer Interface. A major improvement of the proposed approach is that it allows estimation of head poses at a high yaw/pitch angle when compared with existing geometric approaches, does not require expensive data preparation and training, and is generally fast when compared with other approaches.

Shade-grown coffee plantations are often promoted as a conservation strategy for wild birds. However, these agro-ecosystems are actively managed for food production, which may alter bird behaviors or interactions that could change bird health, compared to natural forest. To examine whether there is a difference between the health parameters of wild birds inhabiting shade-grown coffee plantations and natural forest, we evaluated birds in Costa Rica for (1) their general body condition, (2) antibodies to pathogens, (paramyxovirus and Mycoplasma spp.), and (3) the prevalence and diversity of endo-, ecto-, and hemoparasites. We measured exposure to Mycoplasma spp. and paramyxovirus because these are pathogens that could have been introduced with domestic poultry, one mechanism by which these landscapes could be detrimental to wild birds. We captured 1,561 birds representing 75 species. Although seasonal factors influenced body condition, we did not find bird general body condition to be different. A total of 556 birds of 31 species were tested for antibodies against paramyxovirus-1. Of these, five birds tested positive, four of which were from shade coffee. Out of 461 other tests for pathogens (for antibodies and nucleotide detection), none were positive. Pterolichus obtusus, the feather mite of chickens, was found on 15 birds representing two species and all were from shade-coffee plantations. Larvated eggs of Syngamus trachea, a nematode typically associated with chickens, were found in four birds captured in shade coffee and one captured in forest. For hemoparasites, a total of 1,121 blood smears from 68 bird species were examined, and only one species showed a higher prevalence of infection in shade coffee. Our results indicate that shade-coffee plantations do not pose a significant health risk to forest birds, but at least two groups of pathogens may deserve further attention: Haemoproteus spp. and the diversity and identity of endoparasites.

To examine the efficacy of exposure-based cognitive-behavioral therapy (CBT) plus a structured family intervention (FCBT) versus psychoeducation plus relaxation training (PRT) for reducing symptom severity, functional impairment, and family accommodation in youths with obsessive-compulsive disorder (OCD). A total of 71 youngsters 8 to 17 years of age (mean 12.2 years; range, 8-17 years, 37% male, 78% Caucasian) with primary OCD were randomized (70:30) to 12 sessions over 14 weeks of FCBT or PRT. Blind raters assessed outcomes with responders followed for 6 months to assess treatment durability. FCBT led to significantly higher response rates than PRT in ITT (57.1% vs 27.3%) and completer analyses (68.3% vs. 35.3%). Using HLM, FCBT was associated with significantly greater change in OCD severity and child-reported functional impairment than PRT and marginally greater change in parent-reported accommodation of symptoms. These findings were confirmed in some, but not all, secondary analyses. Clinical remission rates were 42.5% for FCBT versus 17.6% for PRT. Reduction in family accommodation temporally preceded improvement in OCD for both groups and child functional status for FCBT only. Treatment gains were maintained at 6 months. FCBT is effective for reducing OCD severity and impairment. Importantly, treatment also reduced parent-reported involvement in symptoms with reduced accommodation preceding reduced symptom severity and functional impairment.

For severely obese patients, bariatric surgery has been recommended as an effective therapy. The Bariataric Surgery and Education (BaSE) study aimed to assess the efficacy of a videoconferencing-based psychoeducational group intervention in patients after bariatric surgery. The BaSE study is a randomized, controlled multicenter clinical trial involving 117 patients undergoing bariatric surgery (mean preoperative body mass index [BMI] 49.9 kg/m(2), SD 6.4). Patients were enrolled between May 2009 and November 2012 and were randomly assigned to receive either conventional postsurgical visits or, in addition, a videoconferencing-based 1-year group program. Primary outcome measures were weight in kilograms, health-related quality of life (HRQOL), and general self-efficacy (GSE). Secondary outcome measures were depression symptoms and eating behavior. 94% of the patients completed the study. Mean weight loss for all patients was 45.9 kg (SD 16.4) 1 year after surgery (mean excess weight loss [EWL] 63%). Intention-to-treat analyses revealed no differences in weight loss, EWL, HRQOL, or self-efficacy between study groups at 1 year after surgery. However, patients with clinically significant depression symptoms (CSD) at baseline assigned to the intervention group (n = 29) had a significantly better HRQOL (P = .03), lower depression scores (P = .02), and a trend for a better EWL (.06) 1 year after surgery compared with the control group (n = 20). We could not prove the efficacy of the group program for the whole study sample. However, results indicate that the intervention is effective for the important subgroup of patients with CSD.

Adherence to treatment homework is associated with positive outcomes in behavioral psychotherapy but compliance to assignments is still often moderate. Whether adherence can be predicted by different types of motivation for the task and whether motivation plays different roles in face-to-face compared to online psychotherapy is unknown. If models of motivation, such as Self-determination theory, can be used to predict patients' behavior, it may facilitate further research into homework promotion. The aims of this study were, therefore, to investigate whether motivation variables could predict adherence to a prescribed assignment in face-to-face and online interventions using a psychotherapy analog model. A total of 100 participants were included in this study and randomized to either a face-to-face or online intervention. Participants in both groups received a psychoeducation session and were given an assignment for the subsequent week. The main outcome measurements were self-reported motivation and adherence to the assignment. Participant in the face-to-face condition reported significantly higher levels of motivation and showed higher levels of adherence compared to participants in the online condition. Adherence to the assignment was positively associated with intrinsic motivation and intervention credibility in the whole sample and especially in the online group. This study shows that intrinsic motivation and intervention credibility are strong predictors of adherence to assignments, especially in online interventions. The results indicate that intrinsic motivation may be partly substituted with face-to-face contact with a therapist. It may also be possible to identify patients with low motivation in online interventions who are at risk of dropping out. Methods for making online interventions more intrinsically motivating without increasing external pressure are needed. clinicaltrials.gov NCT02895308 . Retrospectively registered 30 August 2016.

Tikhonov regularization is a very useful and widely used method for finding stable solutions of ill-posed problems. A good choice of the penalization functional as well as a careful selection of the topologies of the involved spaces is fundamental to the quality of the reconstructions. These choices can be combined with some a priori information about the solution in order to preserve desired characteristics like sparsity constraints for example. To prove convergence and stability properties of this method, one usually has to assume that a minimizer of the Tikhonov functional is known. In practical situations however, the exact computation of a minimizer is very difficult and even finding an approximation can be a very challenging and expensive task if the involved spaces have poor convexity or smoothness properties. In this paper we propose a method to attenuate this gap between theory and practice, applying a gradient-like method to a Tikhonov functional in order to approximate a minimizer. Using only available information, we explicitly calculate a maximal step-size which ensures a monotonically decreasing error. The resulting algorithm performs only finitely many steps and terminates using the discrepancy principle. In particular the knowledge of a minimizer or even its existence does not need to be assumed. Under standard assumptions, we prove convergence and stability results in relatively general Banach spaces, and subsequently, test its performance numerically, reconstructing conductivities with sparsely located inclusions and different kinds of noise in the 2D electrical impedance tomography.

Full Text Available Recent interest in on-orbit proximity operations has pushed towards the development of autonomous GNC strategies. In this sense, optical navigation enables a wide variety of possibilities as it can provide information not only about the kinematic state but also about the shape of the observed object. Various mission architectures have been either tested in space or studied on Earth. The present study deals with on-orbit relative pose and shape estimation with the use of a monocular camera and a distance sensor. The goal is to develop a filter which estimates an observed satellite’s relative position, velocity, attitude, and angular velocity, along with its shape, with the measurements obtained by a camera and a distance sensor mounted on board a chaser which is on a relative trajectory around the target. The filter’s efficiency is proved with a simulation on a virtual target object. The results of the simulation, even though relevant to a simplified scenario, show that the estimation process is successful and can be considered a promising strategy for a correct and safe docking maneuver.

To examine the efficacy of an Internet-delivered cognitive-behavioral therapy (iCBT) program for health anxiety compared to an active psychoeducation control group. Individuals (N = 86, mean age: 30 years, 87% female) with a Diagnostic and Statistical Manual of Mental Disorders (5th ed.) diagnosis of illness anxiety disorder or somatic symptom disorder with health anxiety were randomized to either a 6-lesson clinician-guided iCBT program for health anxiety (n = 45) or an active control group who received anxiety psychoeducation, clinical support, and monitoring (control, n = 41) over a 12-week period. Both groups experienced significant improvements between baseline and posttreatment on self-report measures of health anxiety, depression, general anxiety, and functional impairment. Intention-to-treat analyses indicated that the iCBT group experienced greater improvements in health anxiety on the Short Health Anxiety Inventory (SHAI) compared to controls (between-groups effect size = 1.39, 95% confidence interval [0.87, 1.93]), and a greater proportion of the iCBT group showed clinically reliable change on the SHAI (84% vs. 34% in the control group). Similarly, the iCBT group outperformed the control group on secondary measures of depression, generalized anxiety, functional impairment, maladaptive cognitions, body hypervigilance, safety behaviors and avoidance, and intolerance of uncertainty. Gains were maintained at 3-month follow-up in the iCBT group. iCBT for health anxiety is more effective than psychoeducation, clinical support, and monitoring, and presents an efficacious and accessible treatment option for people with health anxiety.

Evidence regarding the efficacy of psychosocial interventions after bariatric surgery is rare and shows conflicting results. The Bariatric Surgery and Education (BaSE) study aimed to assess the efficacy of a psychoeducational group intervention in patients after bariatric surgery. The BaSE study was a randomized, controlled, multicenter clinical trial involving 117 patients who underwent bariatric surgery. Patients received either conventional postsurgical visits or, in addition, a 1-year psychoeducational group program. The present study evaluated the sustained effects of the intervention program. Mean follow-up duration was 37.9 months (standard deviation [SD] 8.2 months) after surgery. Outcome measures were as follows: body mass index (BMI), weight loss, self-efficacy, depression severity, and health-related quality of life (HRQOL). Groups were compared using an intention-to-treat approach with a mixed model for repeated measurements. A total of 74 patients (63.2%) completed the follow-up (T5) assessment. Mean weight loss for all patients was 43 kg (SD 15.5 kg) at T5 (mean BMI 35.1 kg/m 2 ). Mean excess weight loss was 60.4%. The effects of the surgery during the first postsurgical year were reflected, on average, by both decreasing weight and psychosocial burden. At the T5 time point, patients had slowly started to regain weight and to deteriorate regarding psychosocial aspects. However, at T5, patients who had participated in the intervention program (n = 39) showed significantly lower depression severity scores (p = .03) and significantly higher self-efficacy (p = .03) compared to the control group (n = 35). The 2 groups did not differ regarding weight loss and quality of life. Psychoeducational intervention shows sustained effects on both depression severity scores and self-efficacy.

Our aim was to evaluate caregivers' perceptions of a video, telephone follow-up, and online forum as components of a psychoeducational intervention. Qualitative semistructured face-to-face interviews were conducted with 12 participants two weeks post-intervention. The study was conducted from September of 2012 to May of 2015. Family caregivers were recruited from four home hospice organizations (HCA Hospice Care, Metta Hospice, Singapore Cancer Centre, and Agape Methodist Hospice) and the National Cancer Centre outpatient clinic in Singapore. A purposive sample was employed, and participants were recruited until data saturation. Qualitative interviews were transcribed verbatim. Transcripts were coded and analyzed using content analysis. Two of the research team members were involved in the data analysis. Two-thirds of participants were females (n = 8). Their ages ranged from 22 to 67 (mean = 50.50, SD = 11.53). About two-thirds were married (n = 7). Most participants were caring for a parent (n = 10), one for a spouse, and one for her mother-in-law. Caregivers favored the use of video for delivery of educational information. They liked the visual and audio aspects of the video. The ability to identify with the caregiver and scenarios in the video helped in the learning process. They appreciated telephone follow-ups from healthcare professionals for informational and emotional support. The online forum as a platform for sharing of information and provision of support was not received well by the caregivers in this study. The reasons for this included their being busy, not being computer savvy, rarely surfing the internet, and not feeling comfortable sharing with strangers on an online platform. This study provided insight into caregivers' perceptions of various components of a psychoeducational intervention. It also gave us a better understanding of how future psychoeducational interventions and support for caregivers of persons with advanced cancer could be
Full Text Available We present the Time-Pose control method for the trotting gait of a quadruped robot on flat ground and up a slope. The method, with brief control structure, real-time operation ability and high adaptability, divides quadruped robot control into gait control and pose control. Virtual leg and intuitive controllers are introduced to simplify the model and generate the trajectory of mass centre and location of supporting legs in gait control, while redundancy optimization is used for solving the inverse kinematics in pose control. The models both on flat ground and up a slope are fully analysed, and different kinds of optimization methods are compared using the manipulability measure in order to select the best option. Simulations are performed, which prove that the Time-Pose control method is realizable for these two kinds of environment.

Full Text Available A Gaussian Mixture Model (GMM-based grasp-pose generation method is proposed in this paper. Through offline training, the GMM is set up and used to depict the distribution of the robot's reachable orientations. By dividing the robot's workspace into small 3D voxels and training the GMM for each voxel, a look-up table covering all the workspace is built with the x, y and z positions as the index and the GMM as the entry. Through the definition of Task Space Regions (TSR, an object's feasible grasp poses are expressed as a continuous region. With the GMM, grasp poses can be preferentially sampled from regions with high reachability probabilities in the online grasp-planning stage. The GMM can also be used as a preliminary judgement of a grasp pose's reachability. Experiments on both a simulated and a real robot show the superiority of our method over the existing method.

There are only a few viable options of psychosocial interventions that deal with this specific topic; one of them is psychoeducation, a model that, although it has been used by practitioners for some time, only recently have studies shown its efficacy in clinical practice.Aim: To assess if patients undergoing psychosocial intervention in addition to a pharmacological treatment have better regulation of their biological rhythm than those only using medication.Method: This study is a randomized clinical trial that compares a standard medication intervention to an intervention combined with drugs and psychoeducation. The evaluation of the biological rhythm was made using the Biological Rhythm Interview of Assessment in Neuropsychiatry, an 18-item scale divided in four areas (sleep, activity, social rhythm, and eating pattern. The combined intervention consisted of medication and a short-term psychoeducation model summarized in a protocol of six individual sessions of 1 hour each.Results: The sample consisted of 61 patients with bipolar II disorder, but during the study, there were 14 losses to follow-up. Therefore, the final sample consisted of 45 individuals (26 for standard intervention and 19 for combined. The results showed that, in this sample and time period evaluated, the combined treatment of medication and psychoeducation had no statistically significant impact on the

Despite a good prognosis for most melanoma survivors, many experience substantial fear of new or recurrent melanoma, worry and anxiety about the future, and unmet healthcare needs. In this protocol, we outline the design and methods of the Melanoma Care Study for melanoma survivors at high risk of developing new primary disease. The objective of this study is to evaluate the efficacy and cost-effectiveness of a psycho-educational intervention for improving psychological and behavioural adjustment to melanoma risk. The study design is a two-arm randomised controlled trial comparing a psycho-educational intervention to usual care. The intervention is comprised of a newly-developed psycho-educational booklet and three telephone sessions delivered by a trained psychologist. A total of 154 melanoma survivors at high risk of developing new primary disease who are attending one of three melanoma high risk clinics in New South Wales, Australia, will be recruited. Participants will be assessed at baseline (6 weeks before their high risk clinic dermatological appointment), and then 4 weeks and 6 months after their appointment. If effectiveness of the intervention is demonstrated at 6 months, an additional assessment at 12 months is planned. The primary outcome is fear of new or recurrent melanoma, as assessed by the Fear of Cancer Recurrence Inventory (FCRI). Secondary outcomes include anxiety, depression, unmet supportive care needs, satisfaction with clinical care, knowledge, behavioural adjustment to melanoma risk, quality of life, and cost-effectiveness of the intervention from a health system perspective. Following the intention-to-treat principle, linear mixed models will be used to analyse the data to account for repeated measures. A process evaluation will also be carried out to inform and facilitate potential translation and implementation into clinical practice. This study will provide high quality evidence on the efficacy and cost-effectiveness of a psycho-educational

The Drug Design Data Resource (D3R) ran Grand Challenge 2 (GC2) from September 2016 through February 2017. This challenge was based on a dataset of structures and affinities for the nuclear receptor farnesoid X receptor (FXR), contributed by F. Hoffmann-La Roche. The dataset contained 102 IC50 values, spanning six orders of magnitude, and 36 high-resolution co-crystal structures with representatives of four major ligand classes. Strong global participation was evident, with 49 participants submitting 262 prediction submission packages in total. Procedurally, GC2 mimicked Grand Challenge 2015 (GC2015), with a Stage 1 subchallenge testing ligand pose prediction methods and ranking and scoring methods, and a Stage 2 subchallenge testing only ligand ranking and scoring methods after the release of all blinded co-crystal structures. Two smaller curated sets of 18 and 15 ligands were developed to test alchemical free energy methods. This overview summarizes all aspects of GC2, including the dataset details, challenge procedures, and participant results. We also consider implications for progress in the field, while highlighting methodological areas that merit continued development. Similar to GC2015, the outcome of GC2 underscores the pressing need for methods development in pose prediction, particularly for ligand scaffolds not currently represented in the Protein Data Bank (http://www.pdb.org), and in affinity ranking and scoring of bound ligands.

Painted and photographic portraits of others show an asymmetric bias: people favor their left cheek. Both experimental and database studies confirm that the left cheek bias extends to selfies. To date all such selfie studies have been cross-sectional; whether individual selfie-takers tend to consistently favor the same pose orientation, or switch between multiple poses, remains to be determined. The present study thus examined intra-individual consistency in selfie pose orientations. Two hundred selfie-taking participants (100 male and 100 female) were identified by searching #selfie on Instagram. The most recent 10 single-subject selfies for the each of the participants were selected and coded for type of selfie (normal; mirror) and pose orientation (left, midline, right), resulting in a sample of 2000 selfies. Results indicated that selfie-takers do tend to consistently adopt a preferred pose orientation (α = 0.72), with more participants showing an overall left cheek bias (41%) than would be expected by chance (overall right cheek bias = 31.5%; overall midline bias = 19.5%; no overall bias = 8%). Logistic regression modellng, controlling for the repeated measure of participant identity, indicated that sex did not affect pose orientation. However, selfie type proved a significant predictor when comparing left and right cheek poses, with a stronger left cheek bias for mirror than normal selfies. Overall, these novel findings indicate that selfie-takers show intra-individual consistency in pose orientation, and in addition, replicate the previously reported left cheek bias for selfies and other types of portrait, confirming that the left cheek bias also presents within individuals’ selfie corpora.

The capability of an active spacecraft to accurately estimate its relative position and attitude (pose) with respect to an active/inactive, artificial/natural space object (target) orbiting in close-proximity is required to carry out various activities like formation flying, on-orbit servicing, active debris removal, and space exploration. According to the specific mission scenario, the pose determination task involves both theoretical and technological challenges related to the search for the most suitable algorithmic solution and sensor architecture, respectively. As regards the latter aspect, electro-optical sensors represent the best option as their use is compatible with mass and power limitation of micro and small satellites, and their measurements can be processed to estimate all the pose parameters. Overall, the degree of complexity of the challenges related to pose determination largely varies depending on the nature of the targets, which may be actively/passively cooperative, uncooperative but known, or uncooperative and unknown space objects. In this respect, while cooperative pose determination has been successfully demonstrated in orbit, the uncooperative case is still under study by universities, research centers, space agencies and private companies. However, in both the cases, the demand for space applications involving relative navigation maneuvers, also in close-proximity, for which pose determination capabilities are mandatory, is significantly increasing. In this framework, a review of state-of-the-art techniques and algorithms developed in the last decades for cooperative and uncooperative pose determination by processing data provided by electro-optical sensors is herein presented. Specifically, their main advantages and drawbacks in terms of achieved performance, computational complexity, and sensitivity to variability of pose and target geometry, are highlighted.

To compare muscle activation patterns in 14 dominant side muscles during different yoga poses across three skill levels. Mixed repeated-measures descriptive study. University neuromuscular research laboratory, Miami, US. A group of 36 yoga practitioners (9 M/27 F; mean ± SD, 31.6 ± 12.6 years) with at least 3 months yoga practice experience. Each of the 11 surya namaskar poses A and B was performed separately for 15s and the surface electromyography for 14 muscles were recorded. Normalized root mean square of the electromyographic signal (NrmsEMG) for 14 muscles (5 upper body, 4 trunk, 5 lower body). There were significant main effects of pose for all fourteen muscles except middle trapezius (p<.02) and of skill level for the vastus medialis; p=.027). A significant skill level × pose interaction existed for five muscles (pectoralis major sternal head, anterior deltoid, medial deltoid, upper rectus abdominis and gastrocnemius lateralis; p<.05). Post hoc analyses using Bonferroni comparisons indicated that different poses activated specific muscle groups; however, this varied by skill level. Our results indicate that different poses can produce specific muscle activation patterns which may vary due to practitioners' skill levels. This information can be used in designing rehabilitation and training programs and for cuing during yoga training. Copyright © 2014 Elsevier Ltd. All rights reserved.

This paper explores multi-task learning (MTL) for face recognition. We answer the questions of how and why MTL can improve the face recognition performance. First, we propose a multi-task Convolutional Neural Network (CNN) for face recognition where identity classification is the main task and pose, illumination, and expression estimations are the side tasks. Second, we develop a dynamic-weighting scheme to automatically assign the loss weight to each side task, which is a crucial problem in MTL. Third, we propose a pose-directed multi-task CNN by grouping different poses to learn pose-specific identity features, simultaneously across all poses. Last but not least, we propose an energy-based weight analysis method to explore how CNN-based MTL works. We observe that the side tasks serve as regularizations to disentangle the variations from the learnt identity features. Extensive experiments on the entire Multi-PIE dataset demonstrate the effectiveness of the proposed approach. To the best of our knowledge, this is the first work using all data in Multi-PIE for face recognition. Our approach is also applicable to in-the-wild datasets for pose-invariant face recognition and achieves comparable or better performance than state of the art on LFW, CFP, and IJB-A datasets.

This paper presents a new pose measurement method of microminiature parts that is capable of transforming one dimension (1D) contour size obtained by optical micrometer to three dimension (3D) data with six parameters for microassembly. Pose measurement is one of the most important processes for microminiature parts' alignment and insertion in microassembly. During the past few years, researchers have developed their microassembly systems focusing on visual identification to obtain two or three dimension data with no more than three parameters. Scanning electronic microscope (SEM), optical microscope, and stereomicroscope are applied in their systems. However, as structures of microminiature parts become increasingly complex, six parameters to represent their position and orientation are specifically needed. Firstly, The pose measurement model is established based on the introduction of measuring objects and measuring principle of optical micrometer. The measuring objects are microminiature parts with complex 3D structure. Two groups of two dimension (2D) data are gathered at two different measurement positions. Then part pose with 6 parameters is calculated, including 3 position parameters of feature point of the part and 3 orientation parameters of the part axis. Secondly, pose measurement process for a small shaft, vertical orientation determination, and position parameters obtaining are presented. 2D data is gathered by scanning the generatrix of the part, and valid data is extracted and saved in arrays. A vertical orientation criterion is proposed to determine whether the part is parallel to the Z-axis of the coordinate. If not, 2D data will be fixed into a linear equation using least square algorithm. Then orientation parameters are calculated. Center of Part End (CPE) is selected as feature point of the part, and its position parameters are extracted form two group of 2D data. Finally, a fast pose measurement device is developed and representative

Human action recognition has emerged as an important field in the computer vision community due to its large number of applications such as automatic video surveillance, content based video-search and human robot interaction. In order to cope with the challenges that this large variety of applications present, recent research has focused more on developing classifiers able to detect several actions in more natural and unconstrained video sequences. The invariance discrimination tradeoff in action recognition has been addressed by utilizing a Generalized Hough Transform. As a basis for action representation we transform 3D poses into a robust feature space, referred to as pose descriptors. For each action class a one-dimensional temporal voting space is constructed. Votes are generated from associating pose descriptors with their position in time relative to the end of an action sequence. Training data consists of manually segmented action sequences. In the detection phase valid human 3D poses are assumed as input, e.g. originating from 3D sensors or monocular pose reconstruction methods. The human 3D poses are normalized to gain view-independence and transformed into (i) relative limb-angle space to ensure independence of non-adjacent joints or (ii) geometric features. In (i) an action descriptor consists of the relative angles between limbs and their temporal derivatives. In (ii) the action descriptor consists of different geometric features. In order to circumvent the problem of time-warping we propose to use a codebook of prototypical 3D poses which is generated from sample sequences of 3D motion capture data. This idea is in accordance with the concept of equivalence classes in action space. Results of the codebook method are presented using the Kinect sensor and the CMU Motion Capture Database.

Full Text Available Introduction: Care providers consistently report negative consequences to their mental health as a direct result of their caregiving responsibilities. Specifically, they describe higher levels of distress, mental health problems, and depressive symptoms compared to their non-caregiving matched controls. Powerful Tools for Caregivers (PTC is a national program that aims to empower caregivers to better care for themselves and enhance their self-efficacy. The purpose of the present study was to determine and quantify the effectiveness of the PTC program through pre/post data analysis. Methods: PTC intervention was evaluated at two questionnaire time points: pre-PTC and post-PTC between June 30, 2004 and Oct 16, 2013. Paired sample t-tests (n=409 were conducted using SPSS Statistics Version 22 (IBM Corp., Armonk, NY. Results: PTC increased caregivers who conducted self-care behaviors, who demonstrated self-efficacy, management of depressing emotions and those who used community resources. Conclusion: PTC results in caregivers reporting that they are taking better care of themselves, reacting to their emotions in a healthier manner, gaining more confidence in their caregiving abilities and coping skills, and becoming more knowledgeable about receiving assistance from their community resources.

Implantable cardioverter defibrillators (ICD) were developed for primary and secondary prevention of sudden cardiac death. However, ICD recipients' mortality is significantly predicted by their quality of life (QOL). The aim of this meta-analysis was to evaluate the effects of psycho-educational interventions on QOL in patients with ICDs. We systematically searched PubMed, Medline, Cochrane Library, and CINAHL through April 2015 and references of relevant articles. Studies were reviewed if they met following criteria: (1) randomized controlled trial, (2) participants were adults with an ICD, and (3) data were sufficient to evaluate the effect of psychological or educational interventions on QOL measured by the SF-36 or SF-12. Studies were independently selected and their data were extracted by two reviewers. Study quality was evaluated using a modified Jadad scale. The meta-analysis was conducted using the Cochrane Collaboration's Review Manager Software Package (RevMan 5). Study heterogeneity was assessed by Q statistics and I 2 statistic. Depending on heterogeneity, data were pooled across trials using fixed-effect or random-effect modeling. Seven randomized controlled trials fulfilled the inclusion and exclusion criteria, and included 1017 participants. The psycho-educational interventions improved physical component summary (PCS) scores in the intervention groups more than in control groups (mean difference 2.08, 95 % CI 0.86 to 3.29, p educational interventions improved the physical component, but not the mental component of QOL in patients with ICDs.

Colorectal cancer (CRC) may have a negative impact on a person's quality of life. Psycho-educational interventions for patients with CRC are rarely studied. The purpose of this feasibility trial was to evaluate the effect of a psycho-educational programme (PEP) on the health-related quality of life (HRQL) of patients treated for CRC and anal cancer. Patients with CRC and anal cancer were randomly assigned to a PEP (n = 47) or standard treatment (n = 39). The PEP included informative lectures, discussion, and reflection. HRQL was evaluated using the SF-36 at baseline and 1, 6, and 12 months after the end of the PEP. Patients in the PEP group had significantly better Mental Health scores after 1 month and significantly better Bodily Pain scores after 6 months compared with patients who received standard care. The results of this study indicate that a PEP can have a short-term effect on the mental health and bodily pain of patients treated for CRC and anal cancer when comparing with a control group. The article discusses the methodological difficulties of evaluating an intervention such as this PEP in a clinical setting. Copyright © 2015. Published by Elsevier Ltd.
Full Text Available Background. There is evidence supporting the effectiveness of psychoeducation (PE in patients with symptoms of depression in primary care (PC, but very few studies have assessed this intervention in antidepressant-naïve patients. The aim of this study is to assess the effectiveness of a PE program in these patients, since the use of antidepressant (AD medication may interfere with the effects of the intervention. Methods. 106 participants were included, 50 from the PE program (12 weekly 1.5-hour sessions and 56 from the control group (CG that received the usual care. Patients were assessed at baseline and at 3, 6, and 9 months. The main outcome measures were the Beck Depression Inventory (BDI and remission based on the BDI. The analysis was carried out on an intention-to-treat basis. Results. The PE program group showed remission of symptoms of 40% (P=0.001 posttreatment and 42% (P=0.012 at 6 months. The analysis only showed significant differences in the BDI score posttreatment (P=0.008; effect size Cohen’s d′=0.55. Conclusions. The PE intervention is an effective treatment in the depressive population not treated with AD medication. Before taking an AD, psychoeducational intervention should be considered.

The purpose of this intervention was to develop a therapeutic psycho-educational program that improves quality of life in children and adolescents who are experiencing chronic neurological illness, including epilepsy, and their parents, and to analyze the intervention's feasibility and efficacy and participants' satisfaction. Participants were eight children ( n = 8) and adolescents and their parents; participating children were experiencing chronic neurological illness with psychological comorbidity; children with intellectual impairment were excluded (IQ Stress Index, Beck Depression Inventory, Children's Depression Inventory, and Revised Children's Manifest Anxiety Scale) at pre- and post-intervention, and administered satisfaction surveys following the intervention. Participants' opinions about the program's necessity, contents, and process, and participants' overall program satisfaction were analyzed. Parents and children reported high levels of satisfaction with the program. Externalizing behavioral problems, anxiety/depression, and emotional functioning from quality of life showed improvement after the intervention. Although not statistically significant, total child stress trended downward from pre- to post-intervention. A four-session structured therapeutic psycho-educational program for children and adolescents with chronic neurological illness and their parents was successfully implemented, showing good compliance and high satisfaction and efficacy.

Interventions to prevent postpartum common mental disorders (PCMD) among unselected populations of women have had limited success. The aim was to determine whether What Were We Thinking (WWWT) a gender-informed, psychoeducational programme for couples and babies can prevent PCMD among primiparous women 6 months postpartum. Cluster-randomised controlled trial. 48 Maternal and Child Health Centres (MCHCs) from 6 Local Government Areas in Melbourne, Australia were allocated randomly to usual care (24) or usual care plus WWWT (24). English-speaking primiparous women receiving primary care at trial MCHCs were recruited to the intervention (204) and control (196) conditions. Of these, 187 (91.7%) and 177 (90.3%) provided complete data. WWWT is a manualised programme comprising primary care from a trained nurse, print materials and a face-to-face seminar. Data sources were standardised and study-specific measures collected in blinded computer-assisted telephone interviews at 6 and 26 weeks postpartum. The primary outcome was PCMD assessed by Composite International Diagnostic Interviews and Patient Health Questionnaire (PHQ) Depression and Generalised Anxiety Disorder modules. In intention-to-treat analyses the adjusted OR (AOR) of PCMD in the intervention compared to the usual care group was 0.78 (95% CI 0.38 to 1.63, ns), but mild to moderate anxiety symptoms (AOR 0.58, 95% CI 0.35 to 0.97) and poor self-rated health (AOR 0.46, 95% CI 0.22 to 0.97) were significantly lower. In a per protocol analysis, comparing the full (three component) intervention and usual care groups, the AOR of PCMD was 0.36, (95% CI 0.14 to 0.95). The WWWT seminar was appraised as salient, comprehensible and useful by >85% participants. No harms were detected. WWWT is readily integrated into primary care, enables inclusion of fathers and addresses modifiable risks for PCMD directly. The full intervention appears a promising programme for preventing PCMD, optimising family functioning, and as the

If presented with serious mental illness (SMI), individuals' low help-seeking behaviors and poor adherence to treatment are associated with negative stereotypes and attitudes of healthcare providers. In this study, we examined the effects of a brief psychoeducational program on reducing stigma in pre-clinical medical students. One hundred and two pre-clinical medical students (20-23 years old) were randomly assigned to face-to-face contact + educational lecture (n = 51) condition or video-based contact + educational lecture (n = 51) condition. Measures of pre-clinical medical students' mental illness-related stigma using the Opening Minds Stigma Scale for Health Care Providers (OMS-HC) were administered at pre-, post-treatment, and 1-month follow-up. A 2 (condition: face-to-face contact + educational lecture, video-based contact + educational lecture) by 3 (time: pre-treatment, post-treatment, and 1-month follow-up) mixed model MANOVA was conducted on the Attitudes, Disclosure and Help-Seeking, and Social Distance OMS-HC subscales. Participants' scores on all subscales changed significantly across time, regardless of conditions. To determine how participants' scores changed significantly over time on each subscale, Bonferroni follow-up comparisons were performed to access pairwise differences for the main effect of time. Specifically, pairwise comparisons produced a significant reduction in Social Distance subscale between pre-treatment and post-treatment and between pre-treatment and 1-month follow-up, and a significant increase between post-treatment and 1-month follow-up, regardless of conditions. With respect to the Attitudes and Disclosure and Help-Seeking subscales, pairwise comparisons produced a significant reduction in scores between pre-treatment and post-treatment and a significant increase between post-treatment and 1-month follow-up. Our findings provide additional evidence that educational lecture on mental illness, coupled

Postnatal maternal mental health problems, including depression and anxiety, entail a significant burden globally, and finding cost-effective preventive solutions is a public policy priority. This paper presents a cost-effectiveness analysis of the intervention, What Were We Thinking (WWWT), for the prevention of postnatal maternal mental health problems. The economic evaluation, including cost-effectiveness and cost-utility analyses, was conducted alongside a cluster-randomised trial. 48 Maternal and Child Health Centres in Victoria, Australia. Participants were English-speaking first-time mothers attending participating Maternal and Child Health Centres. Full data were collected for 175 participants in the control arm and 184 in the intervention arm. WWWT is a psychoeducational intervention targeted at the partner relationship, management of infant behaviour and parental fatigue. The evaluation considered public sector plus participant out-of-pocket costs, while outcomes were expressed in the 30-day prevalence of depression, anxiety and adjustment disorders, and quality-adjusted life years (QALYs). Incremental costs and outcomes were estimated using regression analyses to account for relevant sociodemographic, prognostic and clinical characteristics. The intervention was estimated to cost $A118.16 per participant. The analysis showed no statistically significant difference between the intervention and control groups in costs or outcomes. The incremental cost-effectiveness ratios were $A36 451 per QALY gained and $A152 per percentage-point reduction in 30-day prevalence of depression, anxiety and adjustment disorders. The estimate lies under the unofficial cost-effectiveness threshold of $A55 000 per QALY; however, there was considerable uncertainty surrounding the results, with a 55% probability that WWWT would be considered cost-effective at that threshold. The results suggest that, although WWWT shows promise as a preventive intervention for postnatal

Pose estimation relating two-dimensional (2D) images to three-dimensional (3D) rigid object need some known features to track. In practice, there are many algorithms which perform this task in high accuracy, but all of these algorithms suffer from features lost. This paper investigated the pose estimation when numbers of known features or even all of them were invisible. Firstly, known features were tracked to calculate pose in the current and the next image. Secondly, some unknown but good features to track were automatically detected in the current and the next image. Thirdly, those unknown features which were on the rigid and could match each other in the two images were retained. Because of the motion characteristic of the rigid object, the 3D information of those unknown features on the rigid could be solved by the rigid object's pose at the two moment and their 2D information in the two images except only two case: the first one was that both camera and object have no relative motion and camera parameter such as focus length, principle point, and etc. have no change at the two moment; the second one was that there was no shared scene or no matched feature in the two image. Finally, because those unknown features at the first time were known now, pose estimation could go on in the followed images in spite of the missing of known features in the beginning by repeating the process mentioned above. The robustness of pose estimation by different features detection algorithms such as Kanade-Lucas-Tomasi (KLT) feature, Scale Invariant Feature Transform (SIFT) and Speed Up Robust Feature (SURF) were compared and the compact of the different relative motion between camera and the rigid object were discussed in this paper. Graphic Processing Unit (GPU) parallel computing was also used to extract and to match hundreds of features for real time pose estimation which was hard to work on Central Processing Unit (CPU). Compared with other pose estimation methods, this new

People tend to exhibit a leftward bias in posing. Various studies suggest that posing to the left portrays a stronger emotion, whereas posing to the right portrays a more neutral emotion. Religions such as Christianity emphasize the role of strong emotions in religious experience, whereas religions such as Buddhism emphasize the calming of emotions as being important. In the present study, we investigated if the emphasis on emotionality of a religion influences the depiction of their religious figures. Specifically, we coded 484 paintings of Jesus and Buddha from online art databases for whether the deity exhibited a left bias, right bias, or central face presentation. The posing biases were analysed to discover whether paintings of Jesus would more frequently depict a leftward bias than paintings of Buddha. Jesus is more commonly depicted with a leftward bias than Buddha, and Buddha is more commonly depicted with a central face presentation than Jesus. These findings support the idea that the amount of emotionality that is to be conveyed in artwork influences the whether the subject is posed with a leftward bias.

The precise reconstruction and pose estimation of vehicles plays an important role, e.g. for autonomous driving. We tackle this problem on the basis of street level stereo images obtained from a moving vehicle. Starting from initial vehicle detections, we use a deformable vehicle shape prior learned from CAD vehicle data to fully reconstruct the vehicles in 3D and to recover their 3D pose and shape. To fit a deformable vehicle model to each detection by inferring the optimal parameters for pose and shape, we define an energy function leveraging reconstructed 3D data, image information, the vehicle model and derived scene knowledge. To minimise the energy function, we apply a robust model fitting procedure based on iterative Monte Carlo model particle sampling. We evaluate our approach using the object detection and orientation estimation benchmark of the KITTI dataset (Geiger et al., 2012). Our approach can deal with very coarse pose initialisations and we achieve encouraging results with up to 82 % correct pose estimations. Moreover, we are able to deliver very precise orientation estimation results with an average absolute error smaller than 4°.

The purpose of this study was to describe the effects of lower limb positioning and shoe conditions on stability levels of selected single leg ballet poses performed in demi-pointe position. Fourteen female non-professional ballet dancers (mean age of 18.4±2.8 years and mean body mass index of 21.5±2.8kg/m(2)) who had practiced ballet for at least seven years, without any musculoskeletal impairment volunteered to participate in this study. A capacitive pressure platform allowed for the assessment of center of pressure variables related to the execution of three single leg ballet poses in demi pointé position: attitude devant, attitude derriére, and attitude a la second. Peak pressures, contact areas, COP oscillation areas, anterior-posterior and medio-lateral COP oscillations and velocities were compared between two shoe conditions (barefoot versus slippers) and among the different poses. Barefoot performances produced more stable poses with significantly higher plantar contact areas, smaller COP oscillation areas and smaller anterior-posterior COP oscillations. COP oscillation areas, anterior-posterior COP oscillations and medio-lateral COP velocities indicated that attitude a la second is the least challenging and attitude derriére the most challenging pose.

Full Text Available It is a necessary mean to realize the accurate motion control of the manipulator which uses end-effector pose correction method and compensation method. In this article, first, we established the kinematic model and error model of the modular manipulator (WUST-ARM, and then we discussed the measurement methods and precision of the inertial measurement unit sensor. The inertial measurement unit sensor is mounted on the end-effector of modular manipulator, to get the real-time pose of the end-effector. At last, a new inertial measurement unit–based iterative pose compensation algorithm is proposed. By applying this algorithm in the pose compensation experiment of modular manipulator which is composed of low-cost rotation joints, the results show that the inertial measurement unit can obtain a higher precision when in static state; it will accurately feedback to the control system with an accurate error compensation angle after a brief delay when the end-effector moves to the target point, and after compensation, the precision errors of roll angle, pitch angle, and yaw angle are reached at 0.05°, 0.01°, and 0.27° respectively. It proves that this low-cost method provides a new solution to improve the end-effector pose of low-cost modular manipulator.

We describe an innovative protocol for ab initio prediction of ligand crystallographic binding poses and highly effective analysis of large datasets generated for protein-ligand dynamics. We include a procedure for setup and performance of distributed molecular dynamics simulations on cloud computing architectures, a model for efficient analysis of simulation data, and a metric for evaluation of model convergence. We give accurate binding pose predictions for five ligands ranging in affinity from 7 nM to > 200 μM for the immunophilin protein FKBP12, for expedited results in cases where experimental structures are difficult to produce. Our approach goes beyond single, low energy ligand poses to give quantitative kinetic information that can inform protein engineering and ligand design.

Full Text Available Posing research questions is the central ability of the scientific thought. This article examines the ability of sixth grade children to pose researchable questions before and after a three months’ work on a didactic sequence based on the inquiry school model. According to their purpose, the questions asked by children, after reading a text, were classified into researchable questions -susceptible to be empirically explored-, questions about a cause, and questions on a piece of data. The results show that the amount and the type of questions the students were able to pose during the intervention changed, from most of questions on data or information, to most of researchable questions, subsequently, the importance of designing teaching approaches to foster this ability was proved.

This paper addresses the problems of the graphical-based human pose estimation in still images, including the diversity of appearances and confounding background clutter. We present a new architecture for estimating human pose using a Convolutional Neural Network (CNN). Firstly, a Relative Mixture Deformable Model (RMDM) is defined by each pair of connected parts to compute the relative spatial information in the graphical model. Secondly, a Local Multi-Resolution Convolutional Neural Network (LMR-CNN) is proposed to train and learn the multi-scale representation of each body parts by combining different levels of part context. Thirdly, a LMR-CNN based hierarchical model is defined to explore the context information of limb parts. Finally, the experimental results demonstrate the effectiveness of the proposed deep learning approach for human pose estimation.

This work proposes new methods for a microstereotactic frame based on bone cement fixation. Microstereotactic frames are under investigation for minimal invasive temporal bone surgery, e.g. cochlear implantation, or for deep brain stimulation, where products are already on the market. The correct pose of the microstereotactic frame is either adjusted outside or inside the operating room and the frame is used for e.g. drill or electrode guidance. We present a patientspecific, disposable frame that allows intraoperative, sterile pose-setting. Key idea of our approach is bone cement between two plates that cures while the plates are positioned with a mechatronics system in the desired pose. This paper includes new designs of microstereotactic frames, a system for alignment and first measurements to analyze accuracy and applicable load.

A Feature and Pose Constrained Extended Kalman Filter (FPC-EKF) is developed for highly dynamic computationally constrained micro aerial vehicles. Vehicle localization is achieved using only a low performance inertial measurement unit and a single camera. The FPC-EKF framework augments the vehicle's state with both previous vehicle poses and critical environmental features, including vertical edges. This filter framework efficiently incorporates measurements from hundreds of opportunistic visual features to constrain the motion estimate, while allowing navigating and sustained tracking with respect to a few persistent features. In addition, vertical features in the environment are opportunistically used to provide global attitude references. Accurate pose estimation is demonstrated on a sequence including fast traversing, where visual features enter and exit the field-of-view quickly, as well as hover and ingress maneuvers where drift free navigation is achieved with respect to the environment.

Statistical analysis of motion patterns of body joints is potentially useful for detecting and quantifying pathologies. However, building a statistical motion model across different subjects remains a challenging task, especially for a complex joint like the wrist. We present a novel framework for simultaneous registration and segmentation of multiple 3-D (CT or MR) volumes of different subjects at various articulated positions. The framework starts with a pose model generated from 3-D volumes captured at different articulated positions of a single subject (template). This initial pose model is used to register the template volume to image volumes from new subjects. During this process, the Grow-Cut algorithm is used in an iterative refinement of the segmentation of the bone along with the pose parameters. As each new subject is registered and segmented, the pose model is updated, improving the accuracy of successive registrations. We applied the algorithm to CT images of the wrist from 25 subjects, each at five different wrist positions and demonstrated that it performed robustly and accurately. More importantly, the resulting segmentations allowed a statistical pose model of the carpal bones to be generated automatically without interaction. The evaluation results show that our proposed framework achieved accurate registration with an average mean target registration error of 0.34 ±0.27 mm. The automatic segmentation results also show high consistency with the ground truth obtained semi-automatically. Furthermore, we demonstrated the capability of the resulting statistical pose and shape models by using them to generate a measurement tool for scaphoid-lunate dissociation diagnosis, which achieved 90% sensitivity and specificity.

Tracking the pose of instruments is a central problem in image-guided surgery. For microscopic scenarios, optical coherence tomography (OCT) is increasingly used as an imaging modality. OCT is suitable for accurate pose estimation due to its micrometer range resolution and volumetric field of view. However, OCT image processing is challenging due to speckle noise and reflection artifacts in addition to the images' 3D nature. We address pose estimation from OCT volume data with a new deep learning-based tracking framework. For this purpose, we design a new 3D convolutional neural network (CNN) architecture to directly predict the 6D pose of a small marker geometry from OCT volumes. We use a hexapod robot to automatically acquire labeled data points which we use to train 3D CNN architectures for multi-output regression. We use this setup to provide an in-depth analysis on deep learning-based pose estimation from volumes. Specifically, we demonstrate that exploiting volume information for pose estimation yields higher accuracy than relying on 2D representations with depth information. Supporting this observation, we provide quantitative and qualitative results that 3D CNNs effectively exploit the depth structure of marker objects. Regarding the deep learning aspect, we present efficient design principles for 3D CNNs, making use of insights from the 2D deep learning community. In particular, we present Inception3D as a new architecture which performs best for our application. We show that our deep learning approach reaches errors at our ground-truth label's resolution. We achieve a mean average error of 14.89 ± 9.3 µm and 0.096 ± 0.072° for position and orientation learning, respectively. Copyright © 2018 Elsevier B.V. All rights reserved.

The spacecraft pose tracking control problem for an uncertain pursuer approaching to a space target is researched in this paper. After modeling the nonlinearly coupled dynamics for relative translational and rotational motions between two spacecraft, position tracking and attitude synchronization controllers are developed independently by using a robust adaptive control approach. The unknown kinematic couplings, parametric uncertainties, and bounded external disturbances are handled with adaptive updating laws. It is proved via Lyapunov method that the pose tracking errors converge to zero asymptotically. Spacecraft close-range rendezvous and proximity operations are introduced as an example to validate the effectiveness of the proposed control approach.

Determining corresponding regions between an MRI and an X-ray mammogram is a clinically useful task that is challenging for radiologists due to the large deformation that the breast undergoes between the two image acquisitions. In this work we propose an intensity-based image registration framework, where the biomechanical transformation model parameters and the rigid-body transformation parameters are optimised simultaneously. Patient-specific biomechanical modelling of the breast derived from diagnostic, prone MRI has been previously used for this task. However, the high computational time associated with breast compression simulation using commercial packages, did not allow the optimisation of both pose and FEM parameters in the same framework. We use a fast explicit Finite Element (FE) solver that runs on a graphics card, enabling the FEM-based transformation model to be fully integrated into the optimisation scheme. The transformation model has seven degrees of freedom, which include parameters for both the initial rigid-body pose of the breast prior to mammographic compression, and those of the biomechanical model. The framework was tested on ten clinical cases and the results were compared against an affine transformation model, previously proposed for the same task. The mean registration error was 11.6±3.8mm for the CC and 11±5.4mm for the MLO view registrations, indicating that this could be a useful clinical tool. Copyright © 2014 The Authors.

The current research was conducted in the Swat valley, where widespread conflict and militancy had been experienced prior to the field activities. The aim of this trial was to evaluate the feasibility and acceptability of a locally developed psycho-educational intervention. This mixed-methods study incorporated a quantitative and qualitative component. For the quantitative component, trial participants were identified from a cross-sectional study conducted in the earlier phase of the research, with Self-Reporting Questionnaire (SRQ) score of ≥9. Participants with suicidal ideation, severe mental or medical illness, recently given birth or living with another woman with an SRQ score of 9 or above were excluded. Participants fulfilling eligibility were randomized on a 1:1 allocation ratio using simple randomization to the psycho-educational intervention or routine care arm. The intervention arm received two psycho-educational sessions at their homes delivered by local community health worker from the study area. The primary outcome was help-seeking for psychological distress, measured by a semi-structured interview by a researcher blind to the allocation status at 2 months post-intervention. Secondary outcomes include psychological distress and social support measured by SRQ and Multidimensional Scale of Perceived Social Support (MSPSS), respectively, at 2 months post-intervention. Intervention acceptability was explored through in-depth interviews. Local community health workers with no mental health experience successfully delivered the psycho-educational sessions in the community. The uptake of intervention was good and the intervention was taken well by the families and the community health workers. The outcome evaluation was not powered; however, more women sought assistance for their distress from their community health workers in the intervention arm, compared to women in the control arm. This trial showed good acceptance and feasible delivery of a
Full Text Available Pose estimation aims at measuring the position and orientation of a calibrated camera using known image features. The pinhole model is the dominant camera model in this field. However, the imaging precision of this model is not accurate enough for an advanced pose estimation algorithm. In this paper, a new camera model, called incident ray tracking model, is introduced. More importantly, an advanced pose estimation algorithm based on the perspective ray in the new camera model, is proposed. The perspective ray, determined by two positioning points, is an abstract mathematical equivalent of the incident ray. In the proposed pose estimation algorithm, called perspective-ray-based scaled orthographic projection with iteration (PRSOI, an approximate ray-based projection is calculated by a linear system and refined by iteration. Experiments on the PRSOI have been conducted, and the results demonstrate that it is of high accuracy in the six degrees of freedom (DOF motion. And it outperforms three other state-of-the-art algorithms in terms of accuracy during the contrast experiment.

Monocular image-based three-dimensional (3-D) human pose recovery aims to retrieve 3-D poses using the corresponding two-dimensional image features. Therefore, the pose recovery performance highly depends on the image representations. We propose a multispectral embedding-based deep neural network (MSEDNN) to automatically obtain the most discriminative features from multiple deep convolutional neural networks and then embed their penultimate fully connected layers into a low-dimensional manifold. This compact manifold can explore not only the optimum output from multiple deep networks but also the complementary properties of them. Furthermore, the distribution of each hierarchy discriminative manifold is sufficiently smooth so that the training process of our MSEDNN can be effectively implemented only using few labeled data. Our proposed network contains a body joint detector and a human pose regressor that are jointly trained. Extensive experiments conducted on four databases show that our proposed MSEDNN can achieve the best recovery performance compared with the state-of-the-art methods.

A molecular dynamics-based protocol is proposed for finding and scoring protein-ligand binding poses. This protocol uses the recently developed reconnaissance metadynamics method, which employs a self-learning algorithm to construct a bias that pushes the system away from the kinetic traps where it would otherwise remain. The exploration of phase space with this algorithm is shown to be roughly six to eight times faster than unbiased molecular dynamics and is only limited by the time taken to diffuse about the surface of the protein. We apply this method to the well-studied trypsin–benzamidine system and show that we are able to refind all the poses obtained from a reference EADock blind docking calculation. These poses can be scored based on the length of time the system remains trapped in the pose. Alternatively, one can perform dimensionality reduction on the output trajectory and obtain a map of phase space that can be used in more expensive free-energy calculations. PMID:22440749

Full Text Available Aiming at the recognition and location of noncooperative spacecraft, this paper presents a monocular vision pose measurement method based on solar triangle structure. First of all, an autonomous recognition algorithm of feature structure based on sliding window Hough transformation (SWHT and inscribed circle of a triangle is proposed, and the image coordinates of feature points on the triangle can be obtained relying on this algorithm, combined with the P4P algorithm and the structure of spacecraft, calculating the relative pose of target expressed by rotation and translation matrix. The whole algorithm can be loaded into the prewritten onboard program, which will get the autocomplete feature structure extraction and relative pose measurement without human intervention, and this method does not need to mount any markers on the target. Then compare the measured values with the accurate value of the laser tracker, so that a conclusion can be drawn that the maximum position error is lower than 5% and the rotation error is lower than 4%, which meets the requirements of noncooperative spacecraft’s pose measurement for observations, tracking, and docking in the final rendezvous phase.

Full Text Available In this work three different algorithms such as Brute Force Delaunay Triangulation and k-d Tree are analyzed on matching comparison for 3D shape representation. It is intended for developing the pose tracking of moving objects in video surveillance. To determine 3D pose of moving objects some tracking system may require full 3D pose estimation of arbitrarily shaped objects in real time. In order to perform 3D pose estimation in real time each step in the tracking algorithm must be computationally efficient. This paper presents method comparison for the computationally efficient registration of 3D shapes including free-form surfaces. Matching of free-form surfaces are carried out by using geometric point matching algorithm ICP. Several aspects of the ICP algorithm are investigated and analyzed by using specified surface setup. The surface setup processed in this system is represented by simple geometric primitive dealing with objects of free-from shape. Considered representations are a cloud of points.

In 2015, HTC and Valve launched a virtual reality headset empowered with Lighthouse, the cutting-edge space positioning technology. Although Lighthouse is superior in terms of accuracy, latency and refresh rate, its algorithms do not support base station expansion, and is flawed concerning occlusion in moving targets, that is, it is unable to calculate their poses with a small set of sensors, resulting in the loss of optical tracking data. In view of these problems, this paper proposes an improved pose estimation algorithm for cases where occlusion is involved. Our algorithm calculates the pose of a given object with a unified dataset comprising of inputs from sensors recognized by all base stations, as long as three or more sensors detect a signal in total, no matter from which base station. To verify our algorithm, HTC official base stations and autonomous developed receivers are used for prototyping. The experiment result shows that our pose calculation algorithm can achieve precise positioning when a few sensors detect the signal.
