    The aim of this study was to determine secondary school students' levels of Internet addiction and the physical and psychosocial behavior problems they face while using the Internet. This descriptive study was conducted in three state secondary schools in a rural area in the western part of Turkey. This study's sample consisted of 549 students who agreed to participate, with the consent of their families, and who had an Internet connection at home. The data were evaluated using t-tests and variance analyses. In this study the students' score of Internet addiction was at medium level (mean addiction score 44.51 ± 17.90). There were significant differences between the students' Internet addiction scores and the presence of physical behavior problems (going to bed late, skipping meals, eating meals in front of the computer) and psychosocial behavior problems (suffering from conditions such as restlessness, anger, heart palpitations, or tremors when they could not connect to the Internet, decreased relationships with family and friends, feelings of anger, arguing with parents, and finding life boring and empty without an Internet connection).

    Children and adolescents with long-term physical conditions (LTPCs) are at greater risk of developing psychosocial problems. Screening for such problems may be undertaken using validated psychometric instruments to facilitate early intervention. A systematic review was undertaken to identify clinically utilized and psychometrically validated instruments for identifying depression, anxiety, behavior problems, substance use problems, family problems, and multiple problems in children and adolescents with LTPCs. Comprehensive searches of articles published in English between 1994 and 2014 were completed via Medline, Embase, PsycINFO, CINAHL, and Cochrane CENTRAL databases, and by examining reference lists of identified articles and previous related reviews. Forty-four potential screening instruments were identified, described, and evaluated against predetermined clinical and psychometric criteria. Despite limitations in the evidence regarding their clinical and psychometric validity in this population, a handful of instruments, available at varying cost, in multiple languages and formats, were identified to support targeted, but not universal, screening for psychosocial problems in children and adolescents with LTPCs.

    Full Text Available Infertility is a complex situation crisis which is often psychologically-threatening and emotionally stressful for both partners as well as economically expensive and causes physical pain due to the operations performed for diagnosis and treatment purposes. Infertility has physical, psychological, social, emotional and financial impacts. Infertile couples are under a great social pressure, and need to conceal the problem as it is exceptionally private for them. Infertile individuals are destitute of support when they do not share their pregnancy problems with their families and relatives. Couples define their infertility experience as the most stressful experience of their lives.

More rigorous research on psychosocial determinants with close-ended items developed from these open-ended data and with larger sample sizes of students is necessary. Research with parents and school staff will be needed to understand the perceptions of these stakeholder groups key to creating the students' social environment.

    Cancer is a physical disease and also one of the leading clinical manifestations where psychosocial problems are prevalent. Psychosocial problems that these patients may have in the long run include anxiety, uneasiness, mourning, helplessness, fatigue, impairment of concentration, sleep disorders, mental and cognitive reservation, sexual dysfunction, infertility, psychological distress, and psychiatric disorders. Psychosocial problems have a nature of underpinning the emergence of psychological troubles. The prevalence of psychological disorders in patients with cancer range from 29% to 47%. Psychiatric disorders that are likely to be seen are severe stress disorder, adjustment disorder, depressive disorder, and other neurotic disorders. It is considered by the present author that in the event of breast cancer, potential psychiatric disorders may affect prognosis of the disease, adherance to and success of therapy, social and societal functioning, and survival rate. This paper aims to review the psychiatric symptoms and diseases that may develop in patients with breast cancer, which is one of the most frequent types of a globally common disease; i.e., cancer, as well as the impact of psychiatric symptoms on the treatment of disease.

    The study investigated the relationship between psychosocial problems and personality disorders among a sample of 817 Egyptian adolescents (408 males and 409 females). Using 15 subscales from the Adolescent Psychopathology Scale (APS-long form) we assessed prevalence rates of a number of internalizing and externalizing psychosocial disorders. Additionally, we investigated whether there are gender differences in psychopathology among Egyptian adolescents and to what extent can psychosocial problems predict specific personality disorders. Stepwise multiple regression analyses showed that the participants experienced higher levels of PD, AV, and BD. Gender differences were found in certain personality disorders as well as in externalizing and internalizing psychosocial problems. A number of externalizing and internalizing psychosocial problems were highly predictive of specific personality disorders.

    Full Text Available Context: Psychosocial health problems are highly prevalent and one of the hidden public health problems amongst the children and adolescents. Early diagnosis by primary care physicians and prompt referral to the specialist is very important for controlling it. Objectives: To screen all school going children for the risk of psychosocial problems, identify risk factors and refer at risk children to the psychiatrist for counseling. Material and Methods: A Cross sectional study in urban and rural field practice area of a teaching hospital in Pune. A screening tool-the youth report of pediatric symptom checklist (Y-PSC was used .Statistical analysis by Chi square test and Multivariate logistic regression was used as the test for significance. Results: Out of the total 2154 children, 328 (15.2% were found to be at risk of psychosocial problems. Statistically significant difference was observed as per type of management, medium of education, location of the school, age group, class of the student, total members in the family and socioeconomic status. No significant difference was observed as per gender or the type of the family. However after the application of multinomial logistic regression, significant statistical difference was observed only for the type of management running the schools with significantly more number of proportions of psychological disorders seen in students studying in government run schools. Conclusions: Our study clearly brings out the role of management in psychosocial impairment. The psychosocial impairment is about 15.2% with more impairment seen amongst government schools.

    Full Text Available Background: With the availability of better treatment regimen, life span of thalassemic patients is increasing. Chronic nature of thalassemia and its intensive and demanding treatment result in significant psychologic burden on the patients and their families. A lot has been studied about beta-thalassemia major but little attention has been paid to the psychological aspect of this disease. Hence, the study was planned to analyse the psychosocial problems in thalassemic adolescents and young adults. Materials and Methods: This was a cross-sectional study, conducted from January 2007 to March 2008 in thalassemic day-care centre of a tertiary care teaching hospital. Fifty four thalassemic children and controls above 9 years of age were enrolled. Psychosocial assessment done with assessment of Finer Psychopathology using ICMR Symptom checklist (ICMR task force, 1983. The prevalence of various problems was calculated and compared with controls. Student′s t-test and Chi-square test were used for testing differences in variables. Results: Patients were divided into three groups - Group A (10-15 years, 30 patients; Group B (15-20 years, 18 patients, and Group C (20-25 years, 6 patients. In group A, behavior problems were common (12 patients -40% (P< 0.001, significant. In group B, mood disorders were common (8 patients, 44% (P< 0.001, significant. In group C, psychotic symptoms were common (3 patients, 50% (P< 0.05, significant. Conclusion: Our findings support the hypothesis that psychosocial problems are more in thalassemic adolescents and young adults. Psychosocial aspects need to be addressed in the overall treatment of children with thalassemia.

    Full Text Available Psychosocial processes are implicated as mediators of racial/ethnic health disparities via dysregulation of physiological responses to stress. Our aim was to investigate the extent to which factors previously documented as buffering the impact of high-risk family environments on Aboriginal youths' psychosocial functioning were similarly beneficial for their physical health status.We examined the relationship between psychosocial resilience and physical health of urban Aboriginal youth (12-17 years, n = 677 drawn from a representative survey of Western Australian Aboriginal children and their families. A composite variable of psychosocial resilient status, derived by cross-classifying youth by high/low family risk exposure and normal/abnormal psychosocial functioning, resulted in four groups- Resilient, Less Resilient, Expected Good and Vulnerable. Separate logistic regression modeling for high and low risk exposed youth revealed that Resilient youth were significantly more likely to have lower self-reported asthma symptoms (OR 3.48, p<.001 and carer reported lifetime health problems (OR 1.76, p<.04 than Less Resilient youth.The findings are consistent with biopsychosocial models and provide a more nuanced understanding of the patterns of risks, resources and adaptation that impact on the physical health of Aboriginal youth. The results support the posited biological pathways between chronic stress and physical health, and identify the protective role of social connections impacting not only psychosocial function but also physical health. Using a resilience framework may identify potent protective factors otherwise undetected in aggregated analyses, offering important insights to augment general public health prevention strategies.

    2015-01-01

    Physical activity is known to improve emotional experiences, and positive emotions have been shown to lead to important life outcomes, including the development of psychosocial resources. In contrast, time spent sedentary may negatively impact emotional experiences and, consequently, erode psychosocial resources. Two studies tested whether activity independently influenced emotions and psychosocial resources, and whether activity indirectly influenced psychosocial resources through emotional experiences. Using cross-sectional (Study 1a) and longitudinal (Study 1b) methods, we found that time spent physically active independently predicted emotions and psychosocial resources. Mediation analyses suggested that emotions may account for the relation between activity and psychosocial resources. The improved emotional experiences associated with physical activity may help individuals build psychosocial resources known to improve mental health. Study 1a provided first indicators to suggest that, in contrast, sedentary behaviour may reduce positive emotions, which could in turn lead to decrements in psychosocial resources.

    This paper reports on a study of environments in emerging Internet classrooms. At issue for this study is to what extent these 'technological classrooms' are providing a positive learning environment for students. To investigate this issue, this study involved an evaluation of the physical and psychosocial environments in computerized school settings through a combination of questionnaires and inventories that were later cross-referenced to case studies on a subset of these classrooms. Data were obtained from a series of physical evaluations of 43 settings in 24 school locations in British Columbia, Canada and Western Australia. Evaluations consisted of detailed inventories of the physical environment using the Computerised Classroom Environment Inventory (CCEI): an instrument developed specifically for this study. Data on psychosocial aspects of the environment were obtained with the What is Happening in this Class? (WIHIC) questionnaire administered to 1404 high school students making routine use of these computerized classrooms. Potential deficiencies in the physical environment of these locations included problems with individual workspaces, lighting and air quality, whereas deficiencies in the psychosocial environment were confined to the dimension of Autonomy. Further analysis of these classroom environment data indicated that student Autonomy and Task orientation were independently associated with students' Satisfaction with learning and that many physical (e.g. lighting and workspace dimensions) and psychosocial factors (e.g. students' perceptions of Co-operation and Collaboration) were also associated. The results provide a descriptive account of the learning environment in 'technology-rich' classrooms and, further, indicate that ergonomic guidelines used in the implementation of IT in classrooms may have a positive influence on the learning environment.

    2015-04-01

    To examine the psychosocial problems of childhood cancer survivors in Korea and investigate whether such problems are influenced by family management style. Family members of 158 childhood cancer survivors answered a questionnaire on demographic and illness characteristics, described psychosocial problems in their children using the Pediatric Symptom Checklist (PSC), and completed the Family Management Measure (FaMM). Perceived economic status and all six subscales of the FaMM were significantly correlated with children's psychosocial problems. In a multiple regression model, the Family Life Difficulty and Parental Mutuality scales of the FaMM were each independent predictors of psychosocial problems in young cancer survivors. A detailed care plan designed to (1) promote balance between the management of a child's condition and normal family life and (2) encourage parents to share their feelings with one another and provide mutual support should be required to improve psychosocial outcomes for childhood cancer survivors.

    People living with HIV have faced a new situation since the arrival of the antiretroviral treatments. HIV has become a long-term condition, which not only affects physical health, but also causes psychological and social problems because of stigma and discrimination. These challenges present many decisions and dilemmas for people living with HIV, which involve complex emotional and psychological issues. The aim of this study was to examine the psychosocial decision needs of people living with HIV. To undertake the literature review, a search strategy was designed. Sources included databases (Web of Science, Scopus, ProQuest, and PubMed) as well as electronic journals (AIDS and Behavior, AIDS Care, and Social Science and Medicine). The following search terms were used: (HIV) AND (decision making; OR decision need; OR decision) AND (psychosocial; OR psychological; OR social). All languages were included, using articles from 1990 to 2009. The search was conducted from September 2008 to November 2009, and identified 123 articles. After analysis, 46 articles were included for detailed assessment. The results show that people living with HIV face three key decisions: (i) whether or not to disclose their diagnosis to others; (ii) decisions about adherence to treatments; and (iii) decisions about sexual activity and desires about parenthood. Problems associated with these decisions often result in isolation and mental illness such as depression and anxiety, lack of access to social support, and refusal to seek treatment. Despite the importance of HIV and its public health impact, few studies have considered the psychosocial needs of people living with HIV, but the results demonstrated the burden as a consequence of those needs and that greater support would be of benefit to face them in an effective way. Therefore, the results of this review highlight the requirement to develop interventions to support the psychosocial needs of people living with HIV, to accurately reflect

    As suggested earlier we have chosen in this article to discuss only a small group of key physical and psychosocial concerns and needs associated with HIV and AIDS. These were the issues most frequently discussed by a study group of people living with HIV. We recognize, however, that holistic nursing intervention considers the totality of the individual living with HIV: body, mind, and spirit. It is to that end that the discussed nursing diagnoses and interventions are directed. Ultimately, the successful identification of and intervention in HIV related problems rests in the unique relationship between nurse and patient sharing as collaborators in the healing experience. The body of contemporary nursing and behavioral science research in the area of HIV/AIDS continues to grow. Presently the National Center for Nursing Research is supporting studies focusing on such areas as the use of designated versus general care settings for HIV patient care, quality of nursing care in HIV/AIDS, the effects of nurse-managed home care for AIDS patients, stress and coping in caregivers of AIDS children, the testing of interventions for black women with AIDS, and prevention studies (National Center for Nursing Research, personal communication, 1992). Nevertheless, as the HIV pandemic continues to grow and expand its demographic parameters, more research, particularly with such populations as women and children, is urgently needed. Studies exploring prevention issues and symptom management also are most important. Some suggestions for future study include examination of cultural variables associated with coping with HIV and AIDS; longitudinal research on surviving HIV over time; intervention studies to test specific nursing therapeutics in various settings such as hospital, home, and clinic; and finally, research describing the impact of HIV and AIDS on family functioning and adaptation. It is only through continued study of the impact of HIV, on both the individual living with HIV

    We investigated the association of psychosocial problems, menopausal symptoms such as hot flushes, and trends of smoking and use of cosmetics in our previous study. In this follow-up study, we researched psychiatric disorders and psychosocial problems in menopausal women. We designed a cohort study with 577 Japanese women aged 30-64 years. Subjects were selected randomly from among women who visited the department of gender-specific medicine at Tokyo Women's Medical University East Medical Center between June 2010 and September 2011. We analysed trends such as smoking, using cosmetics, and menopausal symptoms and their association with the first lifetime episode of severe depression and anxiety using structured clinical interviews for the DSM-IV (structured clinical interview for DSM-IV, outpatient version [SCID]), the Center for Epidemiological Studies Depression Scale (CES-D) and the State-Trait Anxiety Inventory (STAI). Significant associations were observed between hot flushes, smoking and the frequency of using cosmetics. Furthermore, the trends in cosmetic use and smoking affected not only psychosocial problems, but also physical problems. Younger women suffered from psychosocial problems more than twice the rate of post-menopausal women. Those who reported their first severe depression episode were also affected by severe anxiety disorders and physical problems. By self-checking the frequency of using cosmetics is up to date knowledge of psychosocial mood problems and improving women's quality of life. © 2013 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

    Background. The need for psychosocial support in cancer patients is estimated in the literature at 14-50%. At the Department of Radiation Oncology, Medical University of Vienna, approximately 3,000 patients are seen annually. Due to limited staff resources, highly distressed patients need to be selected for focused support. A multidisciplinary screening questionnaire covering physical, social and psychological problems and needs was successfully implemented in clinical routine. We present the results of a representative sample of 1,500 heterogeneous cancer patients before beginning radiotherapy. Patients and methods. The prevalence rates of physical, social and psychological problems and needs were evaluated. Independent risk factors for critical psychological distress were analyzed in a multivariate logistic regression model, in order to identify vulnerable subgroups for focused psychosocial support. Results. Critical psychological distress was found in 22% of the overall cohort, of whom only 26% reported a need for psychological information. Clinically relevant pain was suffered by 31%. Patients' most frequent complaints were weakness, sleeping difficulties and exhaustion. Consequently, 40% were impaired in activities and 35% reported a requirement for support in daily life. A need for further information was expressed by 37% of patients. Significant risk factors for critical psychological distress included pain, functional status, support requirements and patient-reported symptoms. Differences in tumor type, metastases and sociodemographic variables had no impact on critical psychological distress. Conclusion. Approximately one third of all patients beginning radiotherapy have physical, social and psychological problems and should receive focused psychosocial support. Multivariate analysis reveals that patients with impaired ''physical integrity'' are at a significantly higher risk of experiencing critical psychological distress. (orig.)

    Full Text Available Background: Call centre workers in BPO face unique occupational hazards - mental, physical and psychosocial. Material & Method: A sample 100 call centre workers of both sexes and from two cities Pune and Mumbai were surveyed by both qualitative and quantitative methods for the above health problems. Results: A high proportion of workers faced sleep disturbances and associated mental stress and anxiety. Sleep disturbance and anxiety was significantly more in international call centres compared to domestic. There was also disturbance in circadian rhythms due to night shift. Physical problems such as musculoskeletal disorders, obesity, eye, and hearing problems were also present. Psychosocial problems included disruption in family life, use of tobacco and alcohol, and faulty eating habits. Conclusion: Better personal management, health education and more research is indicated to study the health problems in this emerging occupation.

    Best practice guidelines for the treatment of cancer now advocate for a child- and family-centered model of care and a psychosocial model of risk prevention. However, healthcare professionals (HCPs) report a number of barriers preventing the implementation of psychosocial care, including an absence of tools to help identify psychosocial problems within the family. The aims of this study are to (1) explore the psychometric properties of the Psychosocial Care Checklist (PCCL) and (2) test if the PCCL can differentiate the degree to which HCPs are aware of psychosocial problems within the family (patient, siblings, parents) of a child with cancer. Thirty-seven HCPs caring for a child with cancer completed the PCCL at time 1 (2-4 weeks after diagnosis) and 29 HCPs completed the PCCL at time 2 (2-3 weeks after). The PCCL had strong test-retest reliability for all domains (α > .60) and strong internal consistency for the total PCCL (α = .91). Interrater reliability was moderate for the oncologist-nurse dyad with regard to sibling knowledge (r = 0.56) and total psychosocial knowledge (r = 0.65). Social workers were significantly more knowledgeable than both nurses and oncologists about total family problems (P = .01) and sibling problems (P = .03). Preliminary findings suggest that the PCCL has adequate test-retest reliability and validity and is useful in differentiating the degree to which HCPs are aware of psychosocial problems within the family, with social workers being the most knowledgeable. Using the PCCL may help HCPs to identify psychosocial problems within the family and appropriately allocate psychosocial resources.

    The aim of this research monograph is to present a general account of the applicability of elliptic variational inequalities to the important class of free boundary problems of obstacle type from a unifying point of view of classical Mathematical Physics.The first part of the volume introduces some obstacle type problems which can be reduced to variational inequalities. Part II presents some of the main aspects of the theory of elliptic variational inequalities, from the abstract hilbertian framework to the smoothness of the variational solution, discussing in general the properties of the free boundary and including some results on the obstacle Plateau problem. The last part examines the application to free boundary problems, namely the lubrication-cavitation problem, the elastoplastic problem, the Signorini (or the boundary obstacle) problem, the dam problem, the continuous casting problem, the electrochemical machining problem and the problem of the flow with wake in a channel past a profile.

    Patient-professional communication has been suggested to be a major determinant of treatment outcomes in psychosocial care for children and adolescents. However, the mechanisms involved are largely unknown and no longitudinal studies have been performed. Our aim was, therefore, to assess over the course of 1 year, the impact of patient-centered communication on psychosocial problems of adolescents in psychosocial care, including the routes mediating this impact. We obtained data on 315 adolescents, aged 12-18 years, enrolled in child and adolescent social or mental health care. We assessed patient-centered communication by comparing the needs and experiences of adolescents with regard to three aspects of communication: affective quality, information provision, and shared decision-making. Changes in psychosocial problems comprised those reported by adolescents and their parents between baseline and 1 year thereafter. Potential mediators were treatment adherence, improvement of understanding, and improvement in self-confidence. We found a relationship between unmet needs for affective quality, information provision, and shared decision-making and less reduction of psychosocial problems. The association between the unmet need to share in decision-making and less reduction of psychosocial problems were partially mediated by less improvement in self-confidence (30 %). We found no mediators regarding affective quality and information provision. Our findings confirm that patient-centered communication is a major determinant of treatment outcomes in psychosocial care for adolescents. Professionals should be aware that tailoring their communication to individual patients' needs is vital to the effectiveness of psychosocial care.

    Full Text Available Introduction. There is an increasing body of literature relating musculoskeletal diseases to both job physical exposures and psychosocial outcomes. Relationships between job physical exposure measures and psychosocial factors have not been well examined or quantified. These exploratory analyses evaluate relationships between quantified exposures and psychosocial outcomes. Methods. Individualized quantification of duration, repetition, and force and composite scores of the Strain Index (SI and the Threshold Limit Value for Hand Activity Level (TLV for HAL were compared to 10 psychosocial measures. Relationships and predicted probabilities were assessed using ordered logistic regression. Analyses were adjusted for age, BMI, and gender. Results and Discussion. Among 1834 study participants there were multiple statistically significant relationships. In general, as duration, repetition, and force increased, psychosocial factors worsened. However, general health and mental exhaustion improved with increasing job exposures. Depression was most strongly associated with increased repetition, while physical exhaustion was most strongly associated with increased force. SI and TLV for HAL were significantly related to multiple psychosocial factors. These relationships persisted after adjustment for strong confounders. Conclusion. This study quantified multiple associations between job physical exposures and occupational and nonoccupational psychosocial factors. Further research is needed to quantify the impacts on occupational health outcomes.

    This study examined differences in offending behavior and psychosocial problems between juvenile offenders who have been sexually abused (n=231), physically abused (n=1,568), neglected (n=1,555), exposed to multiple forms of maltreatment (n=1,767), and non-victims (n=8,492). In addition, the moderating effect of gender in the association between type of maltreatment and offending behavior/psychosocial problems was examined. Results showed that violent offenses were more common in victims of physical abuse and victims of multiple forms of abuse than in non-victims, both in boys and girls. In boys, sexual offenses were far more common in victims of sexual abuse than in victims of other or multiple forms of maltreatment or in non-victims. In girls, no group differences were found in sexual offending behavior. For both boys and girls, externalizing problems were relatively common in victims of physical abuse and neglect whereas internalizing problems were relatively common in victims of sexual abuse. In victims of multiple forms of maltreatment, both internalizing and externalizing problems were relatively common. Implications for clinical practice are discussed.

    Full Text Available Abstract Background Longitudinal epidemiological studies involving child/adolescent mental health problems are scarce in developing countries, particularly in regions characterized by adverse living conditions. We examined the influence of psychosocial factors on the trajectory of child/adolescent mental health problems (CAMHP over time. Methods A population-based sample of 6- to 13-year-olds with CAMHP was followed-up from 2002–2003 (Time 1/T1 to 2007–2008 (Time 2/T2, with 86 out of 124 eligible children/adolescents at T1 being reassessed at T2 (sample loss: 30.6%. Outcome: CAMHP at T2 according to the Child Behavior Checklist/CBCL’s total problem scale. Psychosocial factors: T1 variables (child/adolescent’s age, family socioeconomic status; trajectory of variables from T1 to T2 (child/adolescent exposure to severe physical punishment, mother exposure to severe physical marital violence, maternal anxiety/depression; and T2 variables (maternal education, child/adolescent’s social support and pro-social activities. Results Multivariate analysis identified two risk factors for child/adolescent MHP at T2: aggravation of child/adolescent physical punishment and aggravation of maternal anxiety/depression. Conclusions The current study shows the importance of considering child/adolescent physical punishment and maternal anxiety/depression in intervention models and mental health care policies.

  9. Presenting prevalence and management of psychosocial problems in primary care in Flanders.

    2015-01-01

    Psychosocial problems are widespread but reliable data about management are sparse. An overall view is missing and there is a need for a wider framework to include the data available in health care and welfare practice, databases and research output. The question under scope is: how are psychosocial problems presented and handled in primary care in Flanders? A mixed method was used. Using a 'fishbone diagram' (1) we obtained a basic structure to visualize the main (problem) areas and challenges. A literature study (2) and semi-structured interviews with health care and welfare professionals in primary care (3) were performed. Finally, two interdisciplinary focus groups were organized (4). In Flanders, there is no tradition of multidisciplinary psychosocial research in primary care causing a lack of integrated data. Data only exist within disciplines without transdisciplinarity. The data are difficult to interpret due to different labeling and registration processes between disciplines and settings. However, we can find some general trends: assistance to patients with psychosocial problems is based on what can be offered, rather than on patient needs; drug treatment remains popular; referral of patients within primary care or to secondary care does not seem to be obvious. Among all disciplines, there is a great need for more collaboration and considerable advantages are to be expected from the growing emergence of multidisciplinary practices; multiculturalism appears to take an increasingly important place within primary care in Flanders and has implications for the care offered; and treatment effectiveness in psychosocial problems seems to be more related to the person of the caregiver than to a specific discipline, theory or type of treatment. Based on our results, we strongly advise stimulation and organization of integrated (multidisciplinary) research regarding psychosocial problems in primary care and a more consistent registration by the agencies in primary

The existence of one-to-one mappings between different algebras of observables or between different Hilbert spaces allow us to represent and imitate any physical system by any other one (e.g., a bosonic system by a spin-1/2 system). We explain how these mappings can be performed showing quantum networks useful for the efficient evaluation of some physical properties, such as correlation functions and energy spectra.

    Full Text Available Abstract Background The Screening Inventory of Psychosocial Problems (SIPP is a short, validated self-reported questionnaire to identify psychosocial problems in Dutch cancer patients. The one-page 24-item questionnaire assesses physical complaints, psychological complaints and social and sexual problems. Very little is known about the effects of using the SIPP in consultation settings. Our study aims are to test the hypotheses that using the SIPP (a may contribute to adequate referral to relevant psychosocial caregivers, (b should facilitate communication between radiotherapists and cancer patients about psychosocial distress and (c may prevent underdiagnosis of early symptoms reflecting psychosocial problems. This paper presents the design of a cluster randomised controlled trial (CRCT evaluating the effectiveness of using the SIPP in cancer patients treated with radiotherapy. Methods/Design A CRCT is developed using a Solomon four-group design (two intervention and two control groups to evaluate the effects of using the SIPP. Radiotherapists, instead of cancer patients, are randomly allocated to the experimental or control groups. Within these groups, all included cancer patients are randomised into two subgroups: with and without pre-measurement. Self-reported assessments are conducted at four times: a pre-test at baseline before the first consultation and a post-test directly following the first consultation, and three and 12 months after baseline measurement. The primary outcome measures are the number and types of referrals of cancer patients with psychosocial problems to relevant (psychosocial caregivers. The secondary outcome measures are patients' satisfaction with the radiotherapist-patient communication, psychosocial distress and quality of life. Furthermore, a process evaluation will be carried out. Data of the effect-evaluation will be analysed according to the intention-to-treat principle and data regarding the types of referrals

    Although physical activity can potentially reduce symptoms of arthritis, 50% of people with arthritis are insufficiently active. The aim was to identify psychosocial factors associated with increased physical activity in mid-age adults with arthritis who did not meet recommended physical activity levels. Longitudinal cohort study. Data were from 692 insufficiently active men and women (mean age 55 ± 6.6 years) with arthritis, who answered mailed surveys in 2007 and 2009 in the HABITAT study. Increased physical activity was defined as a change of ≥ 200 MET min/week in walking, moderate and vigorous activities from 2007 to 2009. Scale scores were used to measure psychosocial factors including intention, experiences, attitudes, efficacy, barriers, motivation, social support, and health professional advice. Associations between (1) 2007 psychosocial factors and (2) 2007-2009 improvement (≥ +1 standard deviation) in psychosocial factors and increased physical activity were examined with logistic regression models. Results were adjusted for education, body mass index, and self-rated health. Between 2007 and 2009, 296 participants (42.8%) increased their physical activity. Engagement, mastery and physical activity intention in 2007 were associated with this increase in physical activity (engagement OR = 1.11, 99% confidence interval (CI) = 1.05-1.17; mastery OR = 1.12, 99%CI = 1.02-1.22; physical activity intention OR = 1.29, 99%CI = 1.06-1.56). Improved scores for encouragement (OR = 2.07, CI = 1.07-4.01) and self-efficacy (OR =2 .27, CI = 1.30-3.97) were also significantly associated with increased physical activity. Positive physical activity experiences and intentions were predictors of increased physical activity among people with arthritis. Improved physical activity confidence and social support were associated with increased physical activity. It is important to consider these psychosocial factors when planning physical activity interventions for people with

    We present a list of open questions in mathematical physics. After a historical introduction, a number of problems in a variety of different fields are discussed, with the intention of giving an overall impression of the current status of mathematical physics, particularly in the topical fields of classical general relativity, cosmology and the quantum realm. This list is motivated by the recent article proposing 42 fundamental questions (in physics) which must be answered on the road to full enlightenment (Allen and Lidstrom 2017 Phys. Scr. 92 012501). But paraphrasing a famous quote by the British football manager Bill Shankly, in response to the question of whether mathematics can answer the Ultimate Question of Life, the Universe, and Everything, mathematics is, of course, much more important than that.

    Sandia Labs has corporate, lab-wide efforts to enhance the research environment as well as improve physical space. However, these two efforts are usually done in isolation. The integration of physical space design with the nurturing of what we call psychosocial space can foster more efficient and effective creativity, innovation, collaboration, and performance. This paper presents a brief literature review on how academia and industry are studying the integration of physical and psychosocial space and focuses on the efforts that we, the authors, have made to improve the research environment in the Cyber Engineering Research Lab (CERL), home to Group 1460. Interviews with subject matter experts from Silicon Valley and the University of New Mexico plus changes to actual spaces in CERL provided us with six lessons learned when integrating physical and psychosocial space. We describe these six key takeaways in hopes that Sandia will see this area as an evolving research capability that Sandia can both contribute to and benefit from.

    2015-12-01

    The aim of this study was to explore nursing staffs' perceptions of the physical and psychological care needs of elderly residents, their views on the relative importance of these needs and their perceived ability to meet them. The literature reveals that the quality of elder care in nursing homes should comprise both physical and psychosocial care. Despite this, the nursing staffs' perceptions of the physical and psychosocial care provision have not often been researched. As a method cross-sectional research design was used, with structured questionnaires and unstructured interviews. Our sample consisted of members of the nursing staff from four nursing homes in Slovenia (survey: N = 148; interview: N = 16). The resulting data was processed by means of statistical analysis and conventional content analysis. The nursing staff reported more knowledge of, skills with and willingness to meet residents'physical needs than psychosocial needs. On the other hand, communication, conversation, self-care and a home-like environment were considered by nursing staff as marking quality elder care. Consequently, nursing home administrators should try to strengthen psychosocial care provision to improve the residents' quality of life. Conversation, as the most often recognised aspect of psychosocial care, should be promoted, since improvements in this area would not be costly, and each nursing staff member may decide individually how best to include more conversation in the daily routines of elder care provision.

    To enhance physical activity of children with spina bifida, it is important to investigate the correlates of physical activity to support the development of interventions to promote active lifestyles. This study aimed to identify psychosocial correlates of physical activity among children and adolescents with spina bifida. A survey was conducted with 31 students (15 boys), aged 10-17 years with spina bifida. A questionnaire was used to collect data of physical activity, demographic and psychosocial variables (attitudes, sports goal orientation and perceptions). Unadjusted and adjusted binary logistic regressions were performed to examine the relationship of psychosocial factors and physical activity participation. Data were collected in 2013. Only 38.7% reported to participate in both organized and non-organized physical activity. Results showed no relationship between participation in organized and non-organized physical activity and psychosocial correlates. The result of the adjusted regression analysis show that perception of competence (OR = 9.55, 1.06-85.99, p spina bifida. Copyright © 2015 Elsevier Inc. All rights reserved.

    Dental students train in an environment similar to dentists in private practice. The literature reveals that physical and psychosocial stressors in dental schools are associated with adverse health outcomes. While dental educators have provided resources to address psychosocial factors and ergonomics training at the didactic level, the reinforcement of biomechanics at the clinic level has been overlooked. In this article the authors introduce a descriptive analysis of an ergonomics awareness program that expands the ergonomic training by including an assessment of the physical work performed by dental students in the clinic environment.

    Children of asylum seekers are at risk for psychosocial problems because of their flight history and exceptional living circumstances. This study aims to assess the association of sociodemographic factors and asylum procedural factors with psychosocial problems of asylum seekers' children, and differences herein by informant (parents, teachers, and children). To this end, we obtained data on psychosocial problems among a random sample of 267 children aged 4 to 16, living in Dutch asylum seekers' centers, using the multi-informant Strength and Difficulties Questionnaire. The results show that the prevalence rate of psychosocial problems among asylum seekers' children was high. The occurrence was not associated with asylum-procedural variables but only with child-contextual factors such as mental health of the mother and leaving behind a parent in the country of origin. The associations varied in strength by informant. Therefore, preventive and supportive measures to improve psychosocial health of young asylum-seekers should concentrate on these contextual issues.

    This study examines psychosocial functioning in children with neurodevelopmental disorders (NDDs) and/or externalizing behavior problems (EBPs) as compared to children with neither condition. The longitudinal sample, drawn from the Canadian National Longitudinal Survey of Children and Youth, included children who were 6 to 9 years old in Cycle 1 who were followed-up biennially in Cycles 2 and 3 (N = 3476). The associations between NDDs and/or EBPs, child and family socio-demographic characteristics and parenting behaviors (consistency and ineffective parenting), were examined across several measures of child psychosocial functioning: peer relationships, general self-esteem, prosocial behavior and anxiety-emotional problems. Children with NDDs, EBPs, and both NDDs and EBPs self-reported lower scores on general self-esteem. Children with NDDs and both NDDs and EBPs reported lower scores on peer relationships and prosocial behavior. Lastly, children with both NDDs and EBPs self-reported higher scores on anxiety-emotional behaviors. After considering family socio-demographic characteristics and parenting behaviors, these differences remained statistically significant only for children with both NDDs and EBPs. Child age and gender, household income and parenting behaviors were important in explaining these associations. Psychosocial functioning differs for children with NDDs and/or EBPs. Children with both NDDs and EBPs appear to report poorer psychosocial functioning compared to their peers with neither condition. However, it is important to consider the context of socio-demographic characteristics, parenting behaviors and their interactions to understand differences in children's psychosocial functioning. Implication for Rehabilitation: Practitioners may wish to consider complexity in child health by examining a comprehensive set of determinants of psychosocial outcomes as well as comorbid conditions, such as neurodevelopmental disorders (NDDs) and externalizing

    Background Severe stress experienced in early life may have long-term effects on adult physiological and psychological health and well-being. We studied physical and psychosocial functioning in late adulthood in subjects separated temporarily from their parents in childhood during World War II. Methods The 1803 participants belong to the Helsinki Birth Cohort Study, born 1934–44. Of them, 267 (14.8%) had been evacuated abroad in childhood during WWII and the remaining subjects served as controls. Physical and psychosocial functioning was assessed with the Short Form 36 scale (SF-36) between 2001 and 2004. A test for trends was based on linear regression. All analyses were adjusted for age at clinical examination, social class in childhood and adulthood, smoking, alcohol intake, physical activity, body mass index, cardiovascular disease and diabetes. Results Physical functioning in late adulthood was lower among the separated men compared to non-separated men (b = −0.40, 95% confidence interval [95% CI]: −0.71 to −0.08). Those men separated in school age (>7 years) and who were separated for a duration over 2 years had the highest risk for lower physical functioning (b = −0.89, 95% CI: −1.58 to −0.20) and (b = −0.65, 95% CI: −1.25 to −0.05), respectively). Men separated for a duration over 2 years also had lower psychosocial functioning (b = −0.70, 95% CI: −1.35 to −0.06). These differences in physical and psychosocial functioning were not observed among women. Conclusion Early life stress may increase the risk for impaired physical functioning in late adulthood among men. Timing and duration of the separation influenced the physical and psychosocial functioning in late adulthood. PMID:23861956

    Full Text Available Background Regular physical activity can be effective not only in preventing diabetes and managing its complications but also be effective in minimizing the risk of developing other chronic diseases among diabetics. The overall aim of study was to determine probable causes of change in physical activity so as to generate evidences for future interventions and to identify psychosocial covariates of self reported physical activity in recently diagnosed Type 2 diabetes cases. Methods Participants n=478 (239 intervention arm and 239 control arm of an observational cohort were randomized into the ADDITION Plus trial and were recruited from 36 practices in East Anglia region. Participants were people recently diagnosed with diabetes (screen detected and clinically diagnosed within the preceding 3 years were individually randomized and were between the age group of 40-69 years, (mean age 59.2 years. The self reported data regarding physical activity was measured at baseline and one year were used. Demographic and psychosocial (treatment control, consequences, anxiety covariates were assessed at the baseline. Linear univariate and multivariable linear regression analysis was used to quantify the associations between demographic and psychosocial correlates. Results: With regard to the psychosocial correlates(except for participants’ perceptions about the consequences of diabetes, no significant associations with physical activity were found. Treatment control and anxiety failed to predict physical activity. Conclusion The result suggests to further investigate the change in physical activity by including other variables related to demography, other psycho-social and environment influences. Based on the available literature, it is suggested that other factors were found consistently associated with physical activity such as self efficacy, attitude, sensation seeking, family-friend social support, goal orientation, motivation could be studied.

    This study assessed the interaction between physical and psychosocial factors for low back symptoms (LBS) and its consequences (reduced activities and absenteeism) in a developing country. A sample of 1294 Indonesian coal mining workers reported occupational exposures, LBS and its consequences using a self-administered questionnaire. Respondents were placed into one of four combination exposure groups: high physical and high psychosocial (HPhyHPsy); high physical and low psychosocial (HPhyLPsy); low physical and high psychosocial (LPhyHPsy), and; low physical and low psychosocial (LPhyLPsy). The attributable proportion due to interaction between physical and psychosocial factors was examined. Individuals in the HPhyHPsy group were most likely to report LBS (OR 5.42, 95% CI 3.30-8.89), reduced activities (OR 4.89, 95% CI 3.09-7.74), and absenteeism (OR 4.96, 95% CI 3.05-8.06). Interactions between physical and psychosocial factors were present for LBS, reduced activities, and absenteeism; although for LBS and absenteeism the interactions were not significant. Current smokers were more likely to report LBS consequences. Permanent employment and night shift work increased the odds of LBS and its consequences. We conclude that interventions aimed at reducing LBS and its consequences should address both physical and psychosocial factors, with a focus on smokers, permanent employment and night shift work.

    In Vietnam, the co-occurrence (i.e., "syndemic") of psychosocial factors (e.g., depression and substance use) may disproportionately burden male sex workers and increase their HIV risk. A comprehensive survey was conducted among 300 male sex workers in Ho Chi Minh City, Vietnam in 2010. We performed logistic regression to examine the association between the syndemic variable-a count score of the number of five psychosocial conditions endorsed-and unprotected anal sex (UAS) in the past. One-third of participants reported any UAS, and 42 % reported ≥2 psychosocial health problems. In multivariable models, experiencing ≥4 psychosocial health problems was significantly associated with UAS. Every unit increase in number of psychosocial health problems was associated with a 25-30 % increase in odds of UAS. Understanding the syndemic condition and its association with HIV risk among male sex workers in Vietnam may lead to the development of more effective, comprehensive interventions.

    Full Text Available Early psychosocial deprivation can negatively impact the development of executive functions (EF. Here we explore the impact of early psychosocial deprivation on behavioral and physiological measures (i.e. event-related potentials; ERPs of two facets of EF, inhibitory control and response monitoring, and their associations with internalizing and externalizing outcomes in the Bucharest Early Intervention Project (BEIP; Zeanah et al., 2003. This project focuses on two groups of children placed in institutions shortly after birth and then randomly assigned in infancy to either a foster care intervention or to remain in their current institutional setting. A group of community controls was recruited for comparison. The current study assesses these children at 8-years of age examining the effects of early adversity, the potential effects of the intervention on EF and the role of EF skills in socio-emotional outcomes. Results reveal exposure to early psychosocial deprivation was associated with impaired inhibitory control on a flanker task. Children in the foster care intervention exhibited stronger response monitoring compared to children who remained in the institution on the error-related positivity (Pe. Moreover, among children in the foster care intervention those who exhibited stronger error-related negativity (ERN responses had lower levels of socio-emotional behavior problems. Overall, these data identify specific aspects of EF that contribute to adaptive and maladaptive socio-emotional outcomes among children experiencing early psychosocial deprivation.

  5. Intellectual disability among Dutch homeless people: prevalence and related psychosocial problems.

    Barbara Van Straaten

    Full Text Available BACKGROUND: There is a higher prevalence of intellectual disability (ID among homeless people than in the general population. However, little is known about the additional psychosocial problems faced by homeless people with ID. We describe the prevalence of ID in a cohort of homeless people in the Netherlands, and report relationships between ID and psychosocial problems in terms of psychological distress, substance (misuse and dependence, as well as demographic characteristics in this cohort. METHODS: This cross-sectional study is part of a cohort study among homeless people in the four major cities of the Netherlands. Data were derived from 387 homeless people who were interviewed and screened for ID six months after the baseline measurement. Multivariate logistic regression analyses and χ2 tests were performed to analyze relationships between ID, psychosocial problems and demographic characteristics. FINDINGS: Of all cohort members, 29.5% had a suspected ID. Participants with a suspected ID had a higher mean age, were more likely to be male and to fall in the lowest category of education than participants without a suspected ID. Having a suspected ID was related to general psychological distress (OR  = 1.56, p<0.05, somatization (OR  = 1.84, p<0.01, depression (OR  = 1.58, p<0.05 and substance dependence (OR  = 1.88, p<0.05. No relationships were found between a suspected ID and anxiety, regular substance use, substance misuse and primary substance of use. CONCLUSION: The prevalence of ID among Dutch homeless people is higher than in the general population, and is related to more psychosocial problems than among homeless people without ID. Homeless people with a suspected ID appear to be a vulnerable subgroup within the homeless population. This endorses the importance of the extra attention required for this subgroup.

  6. Psychosocial stress and cardiovascular disease risk: the role of physical activity.

    2012-01-01

    Chronic stress and depression are associated with increased risk of cardiovascular disease and poorer prognosis, and physical (in)activity may be a key underlying biobehavioral mechanism. Physical activity has antidepressant effects, and physically fitter, more active individuals seem to be more biologically resilient to psychosocial stressors. This article will present data from a series of population cohort studies and laboratory-based psychophysiological studies to explore the role of physical activity as a protective factor against the effects of psychosocial stress on cardiovascular disease. These mechanisms may improve the treatment and prevention of stress-related illnesses and, thus, has important implications for public health and clinical care of high-risk patients.

    The current study served as a practical and substantive guide to establishing longitudinal measurement invariance of psychosocial measures commonly used in adolescent physical activity (PA) research. Psychosocial data on an initial sample of 878 adolescents (ages 11 - 15) recruited through primary care providers were provided at baseline, 6, 12, and 24 months. The target measures included family support, peer support, decisional balance (pros, cons), self-efficacy, and behavioral strategies. Five of the six psychosocial measures exhibited strict longitudinal measurement invariance, with the 6th measure (self-efficacy) exhibiting strong longitudinal measurement invariance. These findings support the equivalence of these measures across time, and provide the foundation to substantively interpret group differences and associations involving these measures and PA.

    Full Text Available Abstract Background The present study aimed at assessing the psychometric properties of psychosocial determinants of physical activity-related measures in Iranian adolescent girls. Methods Several measures of psychosocial determinants of physical activity were translated from English into Persian using the back-translation technique. These translated measures were administered to 512 ninth and tenth-grade Iranian high school students. Results The results of a series of factor analysis showed that the self-efficacy scale contained a single factor, the social support scale contained two factors: family support and friend support, the physical activity 'pros & cons' scale contained two factors: physical activity pros scale and physical activity cons scale, the change strategies scale contained a single factor, the environment scale also contained a single factor. Chronbach's alphas, mean inter-item correlations and test-retest coefficients showed that these solutions were reliable. Conclusions These preliminary results provide support for using the mentioned scales to measure psychosocial determinants of physical activity in Iranian adolescent girls.

    Full Text Available Abstract Background Questionnaires used by health services to identify children with psychosocial problems are often rather short. The psychometric properties of such short questionnaires are mostly less than needed for an accurate distinction between children with and without problems. We aimed to assess whether a short Computerized Adaptive Test (CAT can overcome the weaknesses of short written questionnaires when identifying children with psychosocial problems. Method We used a Dutch national data set obtained from parents of children invited for a routine health examination by Preventive Child Healthcare with 205 items on behavioral and emotional problems (n = 2,041, response 84%. In a random subsample we determined which items met the requirements of an Item Response Theory (IRT model to a sufficient degree. Using those items, item parameters necessary for a CAT were calculated and a cut-off point was defined. In the remaining subsample we determined the validity and efficiency of a Computerized Adaptive Test using simulation techniques, with current treatment status and a clinical score on the Total Problem Scale (TPS of the Child Behavior Checklist as criteria. Results Out of 205 items available 190 sufficiently met the criteria of the underlying IRT model. For 90% of the children a score above or below cut-off point could be determined with 95% accuracy. The mean number of items needed to achieve this was 12. Sensitivity and specificity with the TPS as a criterion were 0.89 and 0.91, respectively. Conclusion An IRT-based CAT is a very promising option for the identification of psychosocial problems in children, as it can lead to an efficient, yet high-quality identification. The results of our simulation study need to be replicated in a real-life administration of this CAT.

    Full Text Available Problem statement: Sports and movement activities play an important role in the harmonious development of children; Special attention should be paid to the factors influencing their involvement in sportive activities. The aim of this study was related to identifying possible psychosocial correlates of the need for physical education and sports in Romanian society and increasing awareness on the importance of sports in everyday life. Approach: 1100 high school students from the North-Eastern part of Romania answered a series of questionnaires that measured level of sports and movement appreciation, passion for sport, leisure and systematic sport practices, attitude towards bullying, instrumental and final values and, several socio-demographic variables: gender, parents’ level of education, type of high school attended and bullying. Results: The data showed that sport is more associated to boys, to students with low socioeconomic status and, to students attending centrally-located high schools; students who are passionate about sports manifest a negative attitude towards bullying. Conclusion: The results emphasized the need to reconsider Romanian academic curricula in order to stimulate competition activities in schools and to increase the number of sportive clubs and associations.

    Validated questionnaires help community pediatric services to identify psychosocial problems. Our aim was to assess which of three short questionnaires was most suitable for this identification among pre-school children. We included 1,650 children (response 64 %) aged 3-4 years undergoing routine well-child health assessments in 18 services across the Netherlands. Child healthcare professionals (CHPs) interviewed and examined children and parents. Parents were randomized regarding filling out the Strengths and Difficulties Questionnaire (SDQ) or the KIPPPI, a Dutch-origin questionnaire. In addition, all filled out the Ages and Stages Questionnaires: Social-Emotional (ASQ:SE) and the Child Behavior Checklist (CBCL). We assessed the internal consistency and validity of each questionnaire, with CBCL and treatment status as criteria, and the degree to which each questionnaire could improve identification based solely on clinical assessment. The internal consistency of the total problems scale of each questionnaire was satisfactory, Cronbach's alphas varied between 0.75 and 0.98. Only the SDQ discriminated sufficiently between children with and without problems as measured by the CBCL (sensitivity = 0.76 at a cut-off point with specificity = 0.90), in contrast to the other two questionnaires (with sensitivity indices varying between 0.51-0.63). Similar results were found for the treatment status criterion, although sensitivity was lower for all questionnaires. The SDQ seemed to add most to the identification of psychosocial problems by CHPs, but the differences between the SDQ and the ASQ:SE were not statistically significant. The SDQ is the best tool for the identification of psychosocial problems in pre-school children by community paediatric services.

    The aim of this study was to examine the relationship of psychosocial factors, namely, pain catastrophizing, kinesiophobia, and maladaptive coping strategies, with muscle strength, pain, and physical performance in patients with knee osteoarthritis (OA)-related symptoms. A total of 109 women (64 with knee OA-related symptoms) with a mean age of 65.4 years (49-81 years) were recruited for this study. Psychosocial factors were quantified by the Pain Catastrophizing Scale, Tampa Scale for Kinesiophobia, and Pain Coping Inventory. Clinical features were assessed using isometric and isokinetic knee muscle strength measurements, visual analog scale, Western Ontario and McMaster Universities Osteoarthritis Index, and functional tests. Associations were examined using correlation and regression analysis. In knee OA patients, pain catastrophizing, kinesiophobia, and coping strategy explained a significant proportion of the variability in isometric knee extension and flexion strength (6.3%-9.2%), accounting for more overall variability than some demographic and medical status variables combined. Psychosocial factors were not significant independent predictors of isokinetic strength, knee pain, or physical performance. In understanding clinical features related to knee OA, such as muscle weakness, pain catastrophizing, kinesiophobia, and coping strategy might offer something additional beyond what might be explained by traditional factors, underscoring the importance of a biopsychosocial approach in knee OA management. Further research on individual patient characteristics that mediate the effects of psychosocial factors is, however, required in order to create opportunities for more targeted, personalized treatment for knee OA.

    The purposes of this study were to identify the physical, behavioral, and psychosocial consequences of Internet use in undergraduate college students; and to evaluate whether time, social norms, and adopter category predict the consequences of Internet use. Rogers' model for studying consequences of innovation was adapted for this study. A descriptive, correlational design was used. Convenience sampling yielded 293 undergraduate students who answered the online survey. Consequences of Internet use were assessed with the researcher-developed instrument, the Internet Consequences Scale (ICONS). Mean scores on the behavioral and psychosocial subscales of the ICONS indicated positive consequences of Internet use, while the physical consequences subscale revealed negative consequences. Multiple regression analyses revealed a small, but significant, amount of variance in consequences of Internet use that could be explained by time, social norms, and adopter category, thus supporting the adapted model for the study of consequences of Internet use in college students.

    To solve physics problems is a key ability which students should reach during their physics education. Ten years ago we started to develop a Collection of fully solved problems. The structure of problems' solutions is specially designed to substitute tutor's help during lesson and encourage students to solve at least some parts of a problem independently. Nowadays the database contains about 770 fully solved problems in physics in Czech, more than 100 problems in Polish and more than 140 problems in English. Other problems are still being translated. Except for physics problems, the Collection has also a mathematical part, which contains more than 300 fully solved problems in mathematics. This paper follows the presentation of the Collection of solved problems from previous years and introduces a new interface of the Collection, its enhanced functionality, new topics, newly created interface for teachers, user feedback and plans for future development. The database is placed at the website of the Department of Physics Education, Faculty of Mathematics and Physics, Charles University in Prague, the links are: http://reseneulohy.cz/fyzika (Czech version); http://www.physicstasks.eu/ (English version).

    In this review the effect of internet-based support programs on psychosocial and physical symptoms resulting from cancer diagnosis and treatment is analyzed. Selection of studies was based on the following criteria: (non-)randomized controlled trials, performed in adult cancer patients, comparing quantitative psychosocial and/or physical outcomes of an internet-based support program with (a) comparison group(s). Literature search yielded 2032 studies of which 16 fulfilled the eligibility criteria. Three different internet-based support programs were identified: social support groups, online therapy for psychosocial/physical symptoms, and online systems integrating information, support, and coaching services. Outcomes improved by these programs in nine studies. Especially fatigue, social support, and distress improved, regardless of the program type. All online systems showed positive effects, mainly for social support and quality of life. This analysis indicates that internet-based support programs are effective in improving psychosocial and physical symptoms in cancer patients.

    Full Text Available Abstract Background Patients with psychosocial problems may benefit from a variety of community, educational, recreational and voluntary sector resources, but GPs often under-refer to these through lack of knowledge and time. This study evaluated the acceptability and effectiveness of graduate primary care mental health workers (GPCMHWs facilitating access to voluntary and community sector services for patients with psychosocial problems. Methods Patients with psychosocial problems from 13 general practices in London were referred to a GPCMHW Community Link scheme providing information and support to access voluntary and community resources. Patient satisfaction, mental health and social outcomes, and use of primary care resources, were evaluated. Results 108 patients consented to take part in the study. At three-month follow-up, 63 (58% had made contact with a community service identified as suitable for their needs. Most were satisfied with the help provided by the GPCMHW in identifying and supporting access to a suitable service. There was a reduction in the number of patients with a probable mental health problem on the GHQ-12 from 83% to 52% (difference 31% (95% CI, 17% – 44%. Social adjustment improved and frequencies of primary care consultations and of prescription of psychotropic medications were reduced. Conclusion Graduates with limited training in mental health and no prior knowledge of local community resources can help patients with psychosocial problems access voluntary and community services, and patients value such a scheme. There was some evidence of effectiveness in reducing psychosocial and mental health problems.

    Abstract Aims: The current study explored the nature of problematic (addictive) video gaming (PVG) and the association with game type, psychosocial health, and substance use. Methods: Data were collected using a paper and pencil survey in the classroom setting. Three samples were aggregated to achieve a total sample of 8478 unique adolescents. Scales included measures of game use, game type, the Video game Addiction Test (VAT), depressive mood, negative self-esteem, loneliness, social anxiety, education performance, and use of cannabis, alcohol and nicotine (smoking). Results: Findings confirmed problematic gaming is most common amongst adolescent gamers who play multiplayer online games. Boys (60%) were more likely to play online games than girls (14%) and problematic gamers were more likely to be boys (5%) than girls (1%). High problematic gamers showed higher scores on depressive mood, loneliness, social anxiety, negative self-esteem, and self-reported lower school performance. Nicotine, alcohol, and cannabis using boys were almost twice more likely to report high PVG than non-users. Conclusions: It appears that online gaming in general is not necessarily associated with problems. However, problematic gamers do seem to play online games more often, and a small subgroup of gamers – specifically boys – showed lower psychosocial functioning and lower grades. Moreover, associations with alcohol, nicotine, and cannabis use are found. It would appear that problematic gaming is an undesirable problem for a small subgroup of gamers. The findings encourage further exploration of the role of psychoactive substance use in problematic gaming. PMID:25317339

    The aim of this study was to further explore the properties of axis IV in the Diagnostic and statistical manual of mental disorders, 4th edition (DSM-IV). In a naturalistic cross-sectional design, a group (n = 163) of young (18-25 years old) Swedish psychiatric outpatients was assessed according to DSM-IV. Psychosocial and environmental problems/axis IV were evaluated through structured interviewing by a social worker and by self-assessment on a questionnaire. Reliability between professional assessment and self-assessment of axis IV was examined. Concurrent validity of axis IV was also examined. Reliability between professional and self-assessed axis IV was fair to almost perfect, 0.31-0.83, according to prevalence and bias-adjusted kappa. Categories of psychosocial stress and environmental problems were related to the presence of axis I disorders, co-morbidity, personality disorders and decreasing Global Assessment of Functioning (GAF) values. The revised axis IV according to DSM-IV seems to have concurrent validity, but is still hampered by limited reliability.

    In 1983 Finland became the second country in the world, after Sweden, to adopt a law prohibiting all kinds of physical punishment towards children, also by parents. The present investigation was carried out in 2011, 28 years after the law was adopted. Changes in exposure to various types of physical punishment towards respondents born between 1931 and 1996 are presented. A representative sample from Western Finland, consisting of 4,609 respondents (2,632 females, 1,977 males) between 15 and 80 years, filled in a paper-and-pencil questionnaire. A number of psychosocial concomitants were measured. The results showed a significant drop in reports of being slapped and beaten with an object among respondents who were born after the law was adopted. The decline in physical punishment was associated with a similar decline in the number of murdered children. Respondents who had been exposed to higher amounts of physical punishment than average scored significantly higher on alcohol abuse, depression, mental health problems, and schizotypal personality. Divorced respondents had been significantly more physically punished than others. Respondents who had attempted suicide during the last 12 months had been exposed to physical punishment during childhood significantly more often than those who had not attempted suicide.

    This monograph deals with the problems of mathematical physics which are improperly posed in the sense of Hadamard. The first part covers various approaches to the formulation of improperly posed problems. These approaches are illustrated by the example of the classical improperly posed Cauchy problem for the Laplace equation. The second part deals with a number of problems of analytic continuations of analytic and harmonic functions. The third part is concerned with the investigation of the so-called inverse problems for differential equations in which it is required to determine a dif­ ferential equation from a certain family of its solutions.

    2016-01-01

    In this study, we examine introductory physics students' ability to perform analogical reasoning between two isomorphic problems which employ the same underlying physics principles but have different surface features. Three hundred and sixty two students from a calculus-based and an algebra-based introductory physics course were given a quiz in the recitation in which they had to first learn from a solved problem provided and take advantage of what they learned from it to solve another problem (which we call the quiz problem) which was isomorphic. Previous research suggests that the multiple-concept quiz problem is challenging for introductory students. Students in different recitation classes received different interventions in order to help them discern and exploit the underlying similarities of the isomorphic solved and quiz problems. We also conducted think-aloud interviews with four introductory students in order to understand in-depth the difficulties they had and explore strategies to provide better sc...

    Full Text Available BACKGROUND: While fluid intelligence has proved to be central to executive functioning, logical reasoning and other frontal functions, the role of this ability in psychosocial adaptation has not been well characterized. METHODOLOGY/PRINCIPAL FINDINGS: A random-probabilistic sample of 2370 secondary school students completed measures of fluid intelligence (Raven's Progressive Matrices, RPM and several measures of psychological adaptation: bullying (Delaware Bullying Questionnaire, domestic abuse of adolescents (Conflict Tactic Scale, drug intake (ONUDD, self-esteem (Rosenberg's Self Esteem Scale and the Perceived Mental Health Scale (Spanish adaptation. Lower fluid intelligence scores were associated with physical violence, both in the role of victim and victimizer. Drug intake, especially cannabis, cocaine and inhalants and lower self-esteem were also associated with lower fluid intelligence. Finally, scores on the perceived mental health assessment were better when fluid intelligence scores were higher. CONCLUSIONS/SIGNIFICANCE: Our results show evidence of a strong association between psychosocial adaptation and fluid intelligence, suggesting that the latter is not only central to executive functioning but also forms part of a more general capacity for adaptation to social contexts.

    Chronic pain and PTSD are known to hold substantial comorbidity following traumatic injury. Although pharmacological agents have been examined in the treatment of pain and PTSD individually, little is known regarding the relationship of medication use with functioning in patients with comorbid conditions. This research examined the relationships of pain, PTSD, and medication use across physical and psychosocial functioning in patients with chronic pain following motor vehicle injury (N=234). Separate analyses were conducted for opioids, SSRIs, and sedative/anxiolytics, respectively. Several relevant effects were noted: (1) Pain evidenced strong associations with reduced functioning across both physical and psychosocial domains, (2) Opioid use held interactive relationships with PTSD across both functioning domains. Specifically, opioids were associated with greater physical impairment in patients without comorbid PTSD. Opioids also were related to greater psychosocial impairment in patients without PTSD while PTSD was associated with greater impairment in patients not using opioids, (3) Opioid use evidenced a marginal interaction with pain on psychosocial functioning. Opioids were associated with greater psychosocial impairment among patients with high-pain, and high-pain was associated with greater impairment among opioid users, (4) SSRIs held a marginal interaction with PTSD such that PTSD was related to poorer psychosocial functioning only among individuals not using an SSRI, and (5) Anxiolytic use evidenced a marginal interaction with PTSD on physical functioning although no between-group differences were noted. These data suggest that PTSD symptomology may be an important consideration in determining treatment modality for patients experiencing pain subsequent to traumatic injury.

    2016-01-01

    We investigated the effects of student-generated problems on exams. The process was gradual with some training throughout the semester. Initial results were highly positive with the students involved performing significantly better, and showing statistically significant improvement (t = 5.04) compared to the rest of the class, on average. Overall, performance improved when students generated problems. Motivation was a limiting factor. There is significant potential for improving student learning of physics and other problem-based topics.

    2012-06-01

    In this study, we explored informant characteristics as determinants of parent-teacher disagreement on preschoolers' psychosocial problems. Teacher characteristics were included in the analyses, in addition to child and parent factors. Psychosocial problems of 732 4-year olds from a Norwegian community sample were assessed by parents and teachers (CBCL-TRF). Furthermore, teachers reported on their education, experience and relationship to the child. Parental stress and psychopathology were also measured. Teachers rated children considerably lower than their parents did, especially on internalizing problems. When teachers rated more child problems, this was strongly associated with conflict in the teacher-child relationship, which predicted disagreement more than other factors. The highest agreement was on boys' externalizing problems. Girls' behavior was rated much lower by teachers than boys' behavior compared to parents' ratings. Possible teacher perception biases are discussed, such as teacher-child conflict, non-identification of internalizing problems, and same-gender child preference.

    Full Text Available Abstract Background Individuals with autism spectrum disorders (ASDs often display symptoms from other diagnostic categories. Studies of clinical and psychosocial outcome in adult patients with ASDs without concomitant intellectual disability are few. The objective of this paper is to describe the clinical psychiatric presentation and important outcome measures of a large group of normal-intelligence adult patients with ASDs. Methods Autistic symptomatology according to the DSM-IV-criteria and the Gillberg & Gillberg research criteria, patterns of comorbid psychopathology and psychosocial outcome were assessed in 122 consecutively referred adults with normal intelligence ASDs. The subjects consisted of 5 patients with autistic disorder (AD, 67 with Asperger's disorder (AS and 50 with pervasive developmental disorder not otherwise specified (PDD NOS. This study group consists of subjects pooled from two studies with highly similar protocols, all seen on an outpatient basis by one of three clinicians. Results Core autistic symptoms were highly prevalent in all ASD subgroups. Though AD subjects had the most pervasive problems, restrictions in non-verbal communication were common across all three subgroups and, contrary to current DSM criteria, so were verbal communication deficits. Lifetime psychiatric axis I comorbidity was very common, most notably mood and anxiety disorders, but also ADHD and psychotic disorders. The frequency of these diagnoses did not differ between the ASD subgroups or between males and females. Antisocial personality disorder and substance abuse were more common in the PDD NOS group. Of all subjects, few led an independent life and very few had ever had a long-term relationship. Female subjects more often reported having been bullied at school than male subjects. Conclusion ASDs are clinical syndromes characterized by impaired social interaction and non-verbal communication in adulthood as well as in childhood. They also

    2011-04-01

    The aim of this study was to gain a deeper understanding of work-related physical and psychosocial exposure and health symptoms of farm staff working in indoor loose-housing dairy systems in Sweden, and to examine possible associations between exposure and health symptoms of farm staff and disease incidence in their dairy herds. A sample of 41 farm owners or managers and 20 directly employed farm workers participated, each from a Swedish dairy farm with loose-housed cows. Mailed questionnaires comprising 29 questions were used to create four separate indices representing physical exposure, psychosocial exposure, physical symptoms, and psychosocial symptoms. Cow herd incidence rates of common veterinary-reported clinical diseases were calculated based on official records. Partial Spearman rank correlation was used to analyze associations. The study confirmed that physical and psychosocial exposure and health symptoms are not uncommon among owners/managers and employed workers. The study also found that farm owners/managers experience more physical symptoms in dairy herds with lower cow disease incidence rates, while more frequent or intensive exposure to negative psychosocial work environment factors among employed dairy workers is associated with a high herd disease incidence rate.

  8. Using isomorphic problems to learn introductory physics

    2011-08-01

    Full Text Available In this study, we examine introductory physics students’ ability to perform analogical reasoning between two isomorphic problems which employ the same underlying physics principles but have different surface features. Three hundred sixty-two students from a calculus-based and an algebra-based introductory physics course were given a quiz in the recitation in which they had to first learn from a solved problem provided and take advantage of what they learned from it to solve another problem (which we call the quiz problem which was isomorphic. Previous research suggests that the multiple-concept quiz problem is challenging for introductory students. Students in different recitation classes received different interventions in order to help them discern and exploit the underlying similarities of the isomorphic solved and quiz problems. We also conducted think-aloud interviews with four introductory students in order to understand in depth the difficulties they had and explore strategies to provide better scaffolding. We found that most students were able to learn from the solved problem to some extent with the scaffolding provided and invoke the relevant principles in the quiz problem. However, they were not necessarily able to apply the principles correctly. Research suggests that more scaffolding is needed to help students in applying these principles appropriately. We outline a few possible strategies for future investigation.

    To assess the personal, physical and psychosocial factors associated with wrist or hand pain in Australian hospital-based nurses. Wrist or hand pain, associated disability and sickness absence, demographic, occupational, physical, psychosocial and personal factors among nurses working for three hospitals in Melbourne, Australia, were assessed in a cross-sectional study. Factors associated with wrist or hand pain in the past month were assessed using logistic regression. This analysis was based on 1111 participants. The prevalence of wrist or hand pain in the past month was 15.3%. Repeated movements of the wrist or finger >4 h (OR 2.63, 95% CI 1.80 to 3.84), high job strain (1.54, 1.04 to 2.28), job insecurity (1.55, 1.04 to 2.28), somatisation tendency (2.73, 1.75 to 4.26), pain catastrophising (1.56, 1.03 to 2.37), better mental (0.97, 0.95 to 0.99) and physical (0.96, 0.94-0.98) health and well-being were associated with wrist or hand pain in the past month, after adjusting for possible confounding factors. When all significant factors were examined in the same model, repeated movements of the wrist or finger >4 h (2.50, 1.71 to 3.67), somatisation (2.61, 1.65 to 4.13) and better physical health and well-being (0.96, 0.94 to 0.99) remained independently associated with wrist or hand pain in the past month. This study highlights that wrist or hand pain is prevalent in hospital nurses. Workplace physical factors and personal factors were associated with wrist or hand pain. Further longitudinal investigation is needed to examine the predictive nature of these factors.

    The purpose of this study was to explore adolescents’ perceptions of psychosocial influences – personal characteristics, environmental factors and behavioural undertakings – influencing their prolonged involvement in sports and physical activity (PA). A qualitative approach was adopted wherein 16 adolescents (8 boys, 8 girls; mean age 15.9 years), who had been physically active for at least the last 8 years, and sixteen adults identified as their ‘parents’ or ‘guardians’ participated in semi-structured interviews. Interviews were transcribed verbatim and coded using the HyperRESEARCH software. Data were analysed using thematic analysis procedures. Four main themes pertaining to psychosocial influences were identified: 1) personal characteristics; 2) school and community resources; 3) parental support; and 4) social interaction. Except for social interaction, for which participants did not identify challenges, themes are discussed according to their motivational aspects and the challenges they represent for adolescents’ PA involvement. The research has implications for health promotion endeavours directed toward parents of children and adolescents. Given the limitations of a qualitative study, readers are invited to apply the conclusions to their own context.

    Full Text Available Background: The purpose of this study was to investigate the relationship between physical, psychosocial, lifestyle and sociodemographic factors with academic performance in female undergraduate students. Methods: One hundred undergraduate female students from the Faculty of Science at the University of Quebec at Montreal participated in this study (mean age = 24.4 ± 4.6 years old. All participants provided their university transcript and had to complete at least 45 course credits from their bachelor degree. Body composition (DXA, handgrip strength, estimated maximal oxygen consumption (VO2max (Bruce Protocol and blood pressure were measured. Participants also completed a questionnaire on their psychosocial, academic motivation, lifestyle and sociodemographic profile. Results: Significant correlations were observed between GPA with estimated VO2max (r = 0.32, intrinsic motivation toward knowledge (r = 0.23, intrinsic motivation toward accomplishment (r = 0.27 and external regulation (r = -0.30, P = 0.002. In addition, eating breakfast every morning and being an atheist was positively associated with academic performance (P < 0.05. Finally, a stepwise linear regression analysis showed that external regulation, intrinsic motivation toward accomplishment, VO2max levels and eating a daily breakfast explained 28.5 % of the variation in the GPA in our cohort. Conclusions: Results of the present study indicate that motivational, physical and lifestyle factors appear to be predictors of academic performance in female undergraduate students.

    2016-01-01

    Some of the basic concepts of topology are explored through known physics problems. This helps us in two ways, one, in justifying the definitions and the concepts, and two, in showing that some of the familiar things are actually related to the topological analysis of the problem. The problems discussed are taken from classical mechanics, quantum mechanics, statistical mechanics, solid state physics, and biology (DNA), to emphasize some unity in diverse areas of physics. It is the real Euclidean space, $R^d$, with which we are most familiar. Intuitions can therefore be sharpened by appealing to the relevant features of this known space, and often by falling back on to it. This is what is done in this chapter.

    Full Text Available Abstract Background Homeless people have high dropout rates when they participate in therapeutic processes. The causes of this failure are not always known. This study investigates whether dropping-out is mediated by personality disorders or whether psychosocial problems are more important. Method Eighty-nine homeless people in a socio-laboral integration process were assessed. An initial interview was used, and the MCMI II questionnaire was applied to investigate the presence of psychosocial disorders (DSM-IV-TR axis IV. This was designed as an ex post-facto prospective study. Results Personality disorders were very frequent among the homeless people examined. Moreover, the high index of psychosocial problems (axis IV in this population supported the proposal that axis IV disorders are influential in failure to complete therapy. Conclusion The outcomes of the study show that the homeless people examined presented with more psychopathological symptoms, in both axis II and axis IV, than the general population. This supports the need to take into account the comorbidity between these two types of disorder among homeless people, in treatment and in the development of specific intervention programs. In conclusion, the need for more psychosocial treatments addressing the individual problems of homeless people is supported.

    2008-10-01

    As part of an ongoing project to reform the introductory algebra-based physics courses at George Washington University, we are developing a taxonomy of introductory physics problems (TIPP) that establishes a connection between the physics problems, the type of physics knowledge they involve and the cognitive processes they develop in students. This taxonomy will provide, besides an algorithm for classifying physics problems, an organized and relatively easy-to-use database of physics problems that contains the majority of already created text-based and research-based types of problems. In addition, this taxonomy will reveal the kinds of physics problems that are still lacking and that are found to be necessary to enhance students' cognitive development. For this reason, we expect it to be a valuable teaching resource for physics instructors which will enable them to select the problems used in their curricular materials based on the specifics of their students' cognition and the learning objectives they want to achieve in their class. This organization scheme will also provide a framework for creating physics-related assessments with a cognitive component.

    Several studies have been carried out to investigate the effect of child maltreatment on juvenile justice involvement and future criminal life. However, little is known about the impact of other forms of adversity, beyond abuse and neglect, on juvenile delinquency and criminal persistence. The effect of early adversity on psychosocial problems is underexplored, particularly in juvenile delinquents. This study, using the Childhood Adverse Experiences (ACE) questionnaire, a tool accessing the exposure to different types of abuse, neglect and serious household dysfunction, explored the role of each adverse experience on juvenile justice involvement, persistence in crime and psychosocial problems during young adulthood. A Portuguese sample of 75 young adults with official records of juvenile delinquency in 2010/2011, and 240 young adults from a community sample completed ACE questionnaire and measures of psychosocial adjustment. Seven out of ten adverse experiences were significantly more prevalent in young adults with juvenile justice involvement than in the community sample, after matching the main demographic variables. The strongest predictor of juvenile justice involvement and criminal persistence during early adulthood was sexual abuse. Dimensions of child/adolescent emotional maltreatment and a mental illness in the household predicted a set of psychosocial problems in young adulthood. This study indicates that early adversity is significantly related to juvenile justice involvement, criminal persistence and psychosocial problems. This study also suggests that each experience has a different role in this process. There is an urgent need to screen, prevent and stop serious adversity. Future scientific directions and recommendations for policies are provided. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2015-12-01

    Problem solving is a critical element of learning physics. However, traditional instruction often emphasizes the quantitative aspects of problem solving such as equations and mathematical procedures rather than qualitative analysis for selecting appropriate concepts and principles. This study describes the development and evaluation of an instructional approach called Conceptual Problem Solving (CPS) which guides students to identify principles, justify their use, and plan their solution in writing before solving a problem. The CPS approach was implemented by high school physics teachers at three schools for major theorems and conservation laws in mechanics and CPS-taught classes were compared to control classes taught using traditional problem solving methods. Information about the teachers' implementation of the approach was gathered from classroom observations and interviews, and the effectiveness of the approach was evaluated from a series of written assessments. Results indicated that teachers found CPS easy to integrate into their curricula, students engaged in classroom discussions and produced problem solutions of a higher quality than before, and students scored higher on conceptual and problem solving measures.

    While workplace physical exercise can help manage musculoskeletal disorders, less is known about psychosocial effects of such interventions. This aim of this study was to investigate the effect of workplace physical exercise on psychosocial factors among workers with chronic musculoskeletal pain.The trial design was a 2-armed parallel-group randomized controlled trial with allocation concealment. A total of 66 slaughterhouse workers (51 men and 15 women, mean age 45 years [standard deviation (SD) 10]) with upper limb chronic musculoskeletal pain were randomly allocated to group-based strength training (physical exercise group) or individual ergonomic training and education (reference group) for 10 weeks. Social climate was assessed with the General Nordic Questionnaire for Psychological and Social Factors at Work, and vitality and mental health were assessed with the 36-item Short Form Health Survey. All scales were converted to 0 to 100 (higher scores are better). Between-group differences from baseline to follow-up were determined using linear mixed models adjusted for workplace, age, gender, and baseline values of the outcome.Mean baseline scores of social climate, mental health, and vitality were 52.2 (SD 14.9), 79.5 (SD 13.7), and 53.9 (SD 19.7), respectively. Complete baseline and follow-up data were obtained from 30 and 31 from the physical exercise and reference groups, respectively. The between-group differences from baseline to follow-up between physical exercise and reference were 7.6 (95% CI 0.3 to 14.9), -2.3 (95% CI -10.3 to 5.8), and 10.1 (95% CI 0.6 to 19.5) for social climate, mental health, and vitality, respectively. For social climate and vitality, this corresponded to moderate effect sizes (Cohen d = 0.51 for both) in favor of physical exercise. There were no reported adverse events.In conclusion, workplace physical exercise performed together with colleagues improves social climate and vitality among workers with chronic musculoskeletal

    Work related neck and upper limb symptoms have a multi-factorial origin. Possible risk factors are of a physical, psychosocial or personal origin. These factors can reinforce each other and their influence can also be mediated by cultural or societal factors. Initially, most research on neck and upper limb symptoms focused on work-related physical exposure. Nowadays, psychosocial work characteristics are recognized as important risk factors. Various models have been developed to offer frameworks for possible pathways, but their empirical support is still not conclusive. In part I of this paper an overview is presented of the results of recent epidemiological studies on work related psychosocial and personal risk factors for neck and upper limb symptoms. In addition, the interplay between these factors and the possible intermediate role of an individuals work style in this process is explored. In contrast to previous reviews, it is now possible to base the conclusions on the effect of work related psychosocial factors on neck and upper limb symptoms on quite a few longitudinal studies. These studies show that high work demands or little control at work are often related to these symptoms. However, this relationship is neither very strong nor very specific. Perceived stress is studied in not as many studies but more consistently related to neck and upper limb symptoms. This also applies to general distress or other pain (co-morbidity). Job dissatisfaction does not contribute to neck and upper limb symptoms. Too little research on personal characteristics is available to draw any conclusions. It is plausible that behavioural aspects, such as work style, are of importance in the etiology of work related upper limb symptoms. However, studies concerning these factors are promising but too scarce to draw conclusions. Future studies should address these behavioural aspects. In part II, the recent studies on the effectiveness of preventive measures for work related neck and

    Full Text Available Abstract Background Physical, emotional, and psychosocial wellbeing are important domains of function. The aims of this study were to explore the existence of separable groups among 70-year olds with scores representing physical function, perceived quality of life, and emotional wellbeing, and to characterise any resulting groups using demographic, personality, cognition, health and lifestyle variables. Methods We used latent class analysis (LCA to identify possible groups. Results Results suggested there were 5 groups. These included High (n = 515, 47.2% of the sample, Average (n = 417, 38.3%, and Poor Wellbeing (n = 37, 3.4% groups. The two other groups had contrasting patterns of wellbeing: one group scored relatively well on physical function, but low on emotional wellbeing (Good Fitness/ Low Spirits,n = 60, 5.5%, whereas the other group showed low physical function but relatively well emotional wellbeing (Low Fitness/Good Spirits, n = 62, 5.7%. Salient characteristics that distinguished all the groups included smoking and drinking behaviours, personality, and illness. Conclusions Despite there being some evidence of these groups, the results also support a largely one-dimensional construct of wellbeing in old age—for the domains assessed here—though with some evidence that some individuals have uneven profiles.

    A growing number of longitudinal studies report associations between adverse psychosocial factors at work and sleep problems. However, the evidence regarding the direction of these associations and the effects of changes in exposure across time is limited. This study examined the plausibility of normal, reverse, and reciprocal associations between ten psychosocial factors at work and sleep problems. In addition, we analyzed if reduced exposure across time had the anticipated result of reducing the risk of sleep problems. Randomly drawn from the general working-age population, the cohort comprised respondents with an active employee relationship in 2009 and 2013 (N = 5760). Exposures and outcome were measured on two occasions separated by 4 years. We computed several sex-stratified logistic regression models with adjustments for various plausible confounders. We found support for the commonly hypothesized unidirectional forward associations between psychosocial factors at work and sleep problems among women only. Among men, psychosocial stressors at work and sleep problems were reciprocally and reversely related. Nevertheless, reduced exposure levels across time pertaining to effort-reward imbalance (OR = 0.36; 95% CI = 0.19-0.69) and lack of social support (OR = 0.55; 95% CI = 0.32-0.93) among men, and work-family imbalance (OR = 0.26; 95% CI = 0.15-0.46) among women were associated with a robust significant lower risk of sleep problems compared to those in the stable high exposure groups. The study results suggest that preventive measures targeting effort-reward imbalance and lack of social support among men, and work-family imbalance among women, might contribute to reduce the risk of troubled sleep among employees.

    Space crews must be self-reliant to complete long-duration missions successfully. This project involves the development and evaluation of a network of self-guided interactive multimedia programs to train and assist long-duration flyers in the prevention, assessment, and management of psychosocial problems that can arise on extended missions. The system is currently under development and is intended for use both during training and on orbit. A virtual space station 3-dimensional graphic was created to serve as a portal to multimedia-based training, assessment, and intervention resources. Additionally, original content on interpersonal conflict and depression is being developed for the system. Input on the best practices for managing conflict and depression on extended missions was obtained from 13 veteran long-duration flyers, as well as from clinical experts. Formative evaluation of a prototype of the system will be conducted with 10 members of the astronaut corps. Subsequently, the content on conflict and depression will be completed, and the depression self-treatment portion will be evaluated in a randomized controlled trial. Although this study involves developing countermeasures to assist long-duration flyers, it also provides a model that could be applied in many Earthbound settings, both in operational environments and in everyday life.

    Problems are an important instrument for teachers to mediate physics content and for learners to adopt this content. This collection of problems is not only suited to traditional teaching and learning in lectures or student labs, but also to all kinds of new ways of teaching and learning, such as self-study, long-distance teaching, project-oriented learning and the use of remote labs/web experiments. We focus on Rutherford's scattering experiment, electron diffraction, Millikan's experiment and the use of pendulums to measure the dependence of gravitational acceleration on latitude. The collection contains about 50 problems with 160 subtasks and solutions, altogether 100 pages. Structure, content, range and the added value of the problems are described. The whole collection can be downloaded for free from http://rcl.physik.uni-kl.de.

    A growing body of studies have indicated the associations between substance use and psychosocial problems in adolescents. However, few of them have examined whether these psychosocial problems form a syndemic, which means the co-occurrence of psychosocial problems accompanied by additional effects on substance use.We conducted a cross-sectional survey with 82,812 Chinese adolescents who were selected using a multistage random procedure. Bivariate associations were estimated between selected syndemic indicators and adolescent substance use. Multivariate logistic regression was used to estimate the association between the syndemic indicator count score (the count of syndemic indicators) and adolescent substance use. In addition, cluster analysis was used to partition participants reporting at least one of syndemic indicators to assess associations between resolved cluster memberships and adolescent substance use.All selected syndemic indicators were associated with each other and with adolescent substance use. As the number of syndemic indicators increases, stronger associations with substance use were found in our analysis: the range of adjusted OR was from 1.57 (95% CI: 1.38-1.79) for 1 syndemic indicator to 9.45 (95% CI: 7.60-11.76) for 5 or 6 syndemic indicators. There was no effect modification of gender on these additive associations. The multivariate logistic regression indicated that the cluster membership of nonlow SES academic failures has the highest odds of using substance (OR = 2.26, 95% CI: 2.12-2.41), compared to students reporting none syndemic indicators.Our findings support the syndemic hypothesis that adolescents bearing multiple psychosocial problems experience additive risks of using substance. Our findings support that a comprehensive approach to substance use prevention in adolescents would necessitate the involvement of a variety of providers.

    OBJECTIVE To investigate the Brazilian version of Pediatric Symptom Checklist (PSC) as a screening tool to identify psychosocial and emotional problems in schoolchildren from six to 12 years old. METHODS Diagnostic test conducted in a public school of Curitiba, Paraná (Southern Brazil), to evaluate the PSC accuracy and consistency, considering the Child Behavior Checklist (CBCL) as the gold standard. Among 415 parents invited for the study, 145 responded to both PSC and CBCL. The results of the two instruments were compared. PSC and CBCL were considered positive if scores ≥28 and >70 respectively. RESULTS Among the 145 cases, 49 (33.8%) were positive for both PSC and CBCL. The ROC curve showed the PSC score of 21 as the best cutoff point for screening psychosocial and emotional problems, with a sensitivity of 96.8% and a specificity of 86.7%. Regarding the reference cutoff (score ≥28 points), the sensitivity was 64.5% and the specificity, 100.0%, similar to those found in the original version of the tool. CONCLUSIONS The Portuguese version of PSC was effective for early identification of emotional and/or psychosocial problems in a schoolchildren group and may be useful for pediatricians.

The aim of this study was to compare health status and exposure to different work environmental factors among ambulance personnel and the core work force in Denmark. In addition, to examine the association between physical and psychosocial work environment factors and different measures of health among ambulance personnel. Methods Data were taken from a nationwide sample of ambulance personnel and fire fighters (n = 1,691 and was compared to reference samples of the Danish work force. The questionnaire contained measures of physical and psychosocial work environment as well as measures of musculoskeletal pain, mental health, self-rated health and sleep quality. Results Ambulance personnel have half the prevalence of poor self-rated health compared to the core work force (5% vs. 10%. Levels of mental health were the same across the two samples whereas a substantially higher proportion of the ambulance personnel reported musculoskeletal pain (42% vs. 29%. The ambulance personnel had higher levels of emotional demands and meaningfulness of and commitment to work, and substantially lower levels of quantitative demands and influence at work. Only one out of ten aspects of physical work environment was consistently associated with higher levels of musculoskeletal pain. Emotional demands was the only psychosocial work factor that was associated with both poorer mental health and worse sleep quality. Conclusions Ambulance personnel have similar levels of mental health but substantially higher levels of musculoskeletal pain than the work force in general. They are more exposed to emotional demands and these demands are associated with higher levels of poor mental health and poor sleep quality.

    Full Text Available It is a fact that mind and body share an intimate relationship. There are many ways in which mental and physical health impact each other. Psychosocial factors play a part in the pathogenesis of physical health, and oral health is no exception. Chronic and painful oral symptoms lead to psychosocial disorder and at the same time, some patients with psychosocial disorders experience painful oral and facial symptoms. Several investigators have concluded that psychosocial factors play an important role in the pathogenesis of an array of oral problems, ranging from poor oral hygiene to chronic pain disorders, such as temporomandibular joint disorders, burning mouth syndrome, and atypical pain. This review aims at the in-depth analysis of the correlation between psychosocial disorders and various oral symptoms.

    Full Text Available Aim: Presentation of skills and knowledge of medical students in psychiatry or psychosocial medicine in basic study (year 1 to 3 after the introduction of a problem oriented learning curriculum at the Medical Faculty of Berne.Method: Description of the curriculum with the different teaching units, and the evaluation by means of formative tools used by students and tutors.Results: With reference to qualitative comparison students of the problem based learning track showed a better preparation of the different teaching units than did traditional students. Moreover, compared to classical teaching, students in problem based learning rated the commitment of the teachers higher. The formative results showed a better adherence to the teaching modules, a higher effort in self learning and a higher interest in psychological or psychiatric learning items.Discussion: The higher commitment of teachers and the explicit structuring of the teaching contents in psychiatry and psychosocial medicine showed positive effects in the learning strategy of students. Beside the fact that exams have been adapted to the new curriculum one can assume that the learning style has changed. This might be a result of the better learning environment in the new curriculum. However, there is not clear how and to what extent these changes will remain active until the final exams of the medical curriculum when psychosocial contents will be reexamined.Conclusions: The intense commitment of the teachers and the better structuring of the subject matter may lead to a better integration of psychosocial and psychiatric issues into the medical curriculum.

    Full Text Available BACKGROUND: Men who have sex with men (MSM are marginalized, hidden, underserved and at high risk for HIV in Nepal. We examined the association between MSM sub-populations, psychosocial health problems and support, access to prevention and non-use of condoms. METHODS: Between September-November of 2010, a cross-sectional survey on HIV-related risk behavior was performed across Nepal through snowball sampling facilitated by non-governmental organizations, recruiting 339 MSM, age 15 or older. The primary outcomes were: (a non-use of condoms at least once in last three anal sex encounters with men and (b non-use of condoms with women in the last encounter. The secondary outcome was participation in HIV prevention interventions in the past year. RESULTS: Among the 339 MSM interviewed, 78% did not use condoms at their last anal sex with another man, 35% did not use condoms in their last sex with a woman, 70% had experienced violence in the last 12 months, 61% were experiencing depression and 47% had thought of committing suicide. After adjustment for age, religion, marital status, and MSM subpopulations (bisexual, ta, meti, gay, non-use of condoms at last anal sex with a man was significantly associated with non-participation in HIV interventions, experience of physical and sexual violence, depression, repeated suicidal thoughts, small social support network and being dissatisfied with social support. Depression was marginally associated with non-use of condoms with women. The findings suggest that among MSM who reported non-use of condoms at last anal sex, the ta subgroup and those lacking family acceptance were the least likely to have participated in any preventive interventions. CONCLUSIONS: MSM in Nepal have a prevalence of psychosocial health problems in turn associated with high risk behavior for HIV. Future HIV prevention efforts targeting MSM in Nepal should cover all MSM subpopulations and prioritize psychosocial health interventions.

    Directory of Open Access Journals (Sweden)

    Takken Tim

    2010-11-01

    Full Text Available Abstract Background Childhood cancer and its treatment have considerable impact on a child's physical and mental wellbeing. Especially long-term administration of chemotherapy and/or radiotherapy impairs physical fitness both during and after therapy, when children often present with muscle weakness and/or low cardiorespiratory fitness. Physical exercise can improve these two elements of physical fitness, but the positive effects of physical exercise might be further increased when a child's wellbeing is simultaneously enhanced by psychosocial training. Feeling better may increase the willingness and motivation to engage in sports activities. Therefore, this multi-centre study evaluates the short and long-term changes in physical fitness of a child with a childhood malignancy, using a combined physical exercise and psychosocial intervention program, implemented during or shortly after treatment. Also examined is whether positive effects on physical fitness reduce inactivity-related adverse health problems, improve quality of life, and are cost-effective. Methods This multi-centre randomized controlled trial compares a combined physical and psychosocial intervention program for children with cancer, with care as usual (controls. Children with cancer (aged 8-18 years treated with chemotherapy and/or radiotherapy, and who are no longer than 1 year post-treatment, are eligible for participation. A total of 100 children are being recruited from the paediatric oncology/haematology departments of three Dutch university medical centres. Patients are stratified according to pubertal stage (girls: age ≤10 or >10 years; boys: ≤11 or >11 years, type of malignancy (haematological or solid tumour, and moment of inclusion into the study (during or after treatment, and are randomly assigned to the intervention or control group.

    The subject of this thesis is in the area of Applied Mathematics known as Inverse Problems. Inverse problems are those where a set of measured data is analysed in order to get as much information as possible on a model which is assumed to represent a system in the real world. We study two inverse problems in the fields of classical and quantum physics: QCD condensates from tau-decay data and the inverse conductivity problem. We use a functional method which allows us to extract within rather general assumptions phenomenological parameters of QCD (the condensates) from a comparison of the time-like experimental data with asymptotic space-like results from theory. The price to be paid for the generality of assumptions is relatively large errors in the values of the extracted parameters. Although we do not claim that our method is superior to other approaches, we hope that our results lend additional confidence to the numerical results obtained with the help of methods based on QCD sum rules.

    Full Text Available Objective. Identification of the factors that influence sedentary behaviour in older adults is important for the design of appropriate intervention strategies. In this study, we determined the prevalence of sedentary behaviour and its association with physical, cognitive, and psychosocial status among older adults residing in Assisted Living (AL. Methods. Participants (n=114, mean age = 86.7 from AL sites in British Columbia wore waist-mounted activity monitors for 7 consecutive days, after being assessed with the Timed Up and Go (TUG, Montreal Cognitive Assessment (MoCA, Short Geriatric Depression Scale (GDS, and Modified Fall Efficacy Scale (MFES. Results. On average, participants spent 87% of their waking hours in sedentary behaviour, which accumulated in 52 bouts per day with each bout lasting an average of 13 minutes. Increased sedentary behaviour associated significantly with scores on the TUG (r=0.373, p<0.001 and MFES (r=-0.261, p=0.005, but not with the MoCA or GDS. Sedentary behaviour also associated with male gender, use of mobility aid, and multiple regression with increased age. Conclusion. We found that sedentary behaviour among older adults in AL associated with TUG scores and falls-related self-efficacy, which are modifiable targets for interventions to decrease sedentary behaviour in this population.

    Fear of falling (FF) can have multiple adverse consequences in the elderly. Although there are various fall prevention programs, little is known of FF and its associated characteristics. This study examined FF-associated physical and psychosocial factors in older Chinese men living in a veterans home in southern Taiwan. Subjects with a recent episode of delirium, of bed-ridden or wheelchair-bound status, severe hearing impairment or impaired cognition were excluded. Overall, 371 residents (mean age 82.1 ± 5.11 years, all males) participated. The prevalence of FF was 25.3%. Univariate analysis revealed that subjects in the FF group were older age, having lower education level, poorer sitting and standing balance, poorer activities of daily living (ADL), more depressive symptoms, higher chances of using walking aids, neurologic diseases, and a history of fall within the past 6 months. Logistic regression showed that depressive symptoms (odds ratio = OR = 6.73, 95%CI: 3.03-14.93, p FF.

(1 To describe the epidemiological and medical features of a sample with LLA and LLD in childhood and (2 to explore their relationship with subsequent physical and psychosocial functions in adulthood. Methods. Cross-sectional survey. Demographics, medical data, Locomotor Capabilities Index (LCI, and Discomfort-Engagement in Everyday Activities Involving Revealing the Body Scale (D-EEARB were collected from thirty-two adults who suffered from LLA in childhood or LLD. Results. Most of the sample (53.1% males was working (84.4%, living independently (75%, and single (75%. Mean age was 33.16 (SD = 7.64, range 18–50. Leading causes for LLA were traumatic (40.6% and oncologic (25%. LLD was present in 6 cases (18.8%. LCI scores revealed a high performance among males (t17,464=2.976, p=.008. D-EEARB scores showed that 56.25% stated feeling “quite” or “totally comfortable” in situations which involved revealing their body, but 43.75% stated the contrary (“uncomfortable” or “very uncomfortable”. LLD and traumatic LLA show higher scores in D-EEARB than vascular and oncological LLA (χ2=7.744, df = 3, p=.05. Conclusions. Adults suffering from LLDs and LLAs during childhood seem to perform well once they are adults. However, 43.75% of patients express considerable discomfort in situations that involve revealing the body.

    Productivity is the essential organizational outcome. It is vaguely understood and difficult to quantify, especially at the individual level in office companies. Our objective was to quantify and describe the part of productivity, which is systematically influenced by the indoor environment. We, therefore, introduce the concept 'indoor productivity,' which is defined by measuring operations. We used the multivariate method Marker Object Projection to transform questionnaire data into an 'indoor productivity index' (IPI), which reflects the relative impact of the variables that systematically influence indoor productivity. The reasoning behind IPI is that indoor productivity cannot be separated from experienced indoor environment and wellness at work. IPI is calculated for each respondent based on own, colleagues', and two fictive respondents' answers. Conservatively, IPI was calculated to constitute about 25% of what determines the productivity of an individual. By using IPI as dependent variable in multiple regression analyses, the relative contribution of all indoor variables was identified. Physical indoor variables were as important as psychosocial ones. During the cold seasons, 'dry air' was the most important factor reducing IPI.

    Attempts of designing economics along the lines of natural sciences (in particular, physics) with the use of mathematical modeling are reviewed. This area of research has come to be known as physical economics. Some topical questions of market economics are discussed; specifically, whether the market equilibrium is unique, whether transitions between stationary states are possible, and, if so, how these transitions proceed. By analogy with physics, the apparatus of mathematical modeling is widely used in answering these questions. It is shown that, under given external conditions, a self-sufficient country can be in two stationary, stable states - either in a high-productivity (HP) or in a low-productivity (LP) state. Transitions between them appear to be either an 'economical crisis' or an 'economical miracle'. It is shown that, for contemporary Russia, the crisis is already over, and the country is now in a stable LP state. Possible transitions to a HP state are discussed. The distributions of social elements over liquid accumulations and incomes are considered. It is shown that, in present-day Russia, these distributions are bimodal, meaning the coexistence of the poor and the wealthy with virtually no middle layer in between. In the tail of the distribution, a very small number of very wealthy people are present. (reviews of topical problems)

    Workplace bullying is a potent stressor that may increase sleep problems. Since physical fitness improves resilience to stress, it seems plausible that recreational physical activities may moderate the association between bullying and sleep. The study aimed to examine prospectively whether (i) bullying increases the risk of sleep problems, and (ii) the association between bullying and sleep problems is moderated by leisure-time physical activity (LTPA). The study sample comprised a cohort of public and private sector employees, who were enrolled into the Work Bullying and Harassment (WBH) cohort (N=3278) or the Psychosocial Risk Factors for Stress and Mental Disease (PRISME) cohort (N=4455). We measured workplace bullying using one question that was preceded by a definition of bullying. We used the Karolinska sleep questionnaire to assess sleep problems. The number of hours per week spent on LTPA estimated the degree of physical activity. Workplace bullying at baseline (T1) was associated with awakening problems and lack of restful sleep at follow-up (T2) but not with overall sleep problems and disturbed sleep. T1-LTPA did not moderate the association between T1-workplace bullying and T2-sleep problems. We found support that workplace bullying is related to development of T2-sleep problems, but this association seems not to be modified by LTPA.

    The subject of this thesis is in the area of Applied Mathematics known as Inverse Problems. Inverse problems are those where a set of measured data is analysed in order to get as much information as possible on a model which is assumed to represent a system in the real world. We study two inverse problems in the fields of classical and quantum physics: QCD condensates from tau-decay data and the inverse conductivity problem. Despite a concentrated effort by physicists extending over many years, an understanding of QCD from first principles continues to be elusive. Fortunately, data continues to appear which provide a rather direct probe of the inner workings of the strong interactions. We use a functional method which allows us to extract within rather general assumptions phenomenological parameters of QCD (the condensates) from a comparison of the time-like experimental data with asymptotic space-like results from theory. The price to be paid for the generality of assumptions is relatively large errors in the values of the extracted parameters. Although we do not claim that our method is superior to other approaches, we hope that our results lend additional confidence to the numerical results obtained with the help of methods based on QCD sum rules. EIT is a technology developed to image the electrical conductivity distribution of a conductive medium. The technique works by performing simultaneous measurements of direct or alternating electric currents and voltages on the boundary of an object. These are the data used by an image reconstruction algorithm to determine the electrical conductivity distribution within the object. In this thesis, two approaches of EIT image reconstruction are proposed. The first is based on reformulating the inverse problem in terms of integral equations. This method uses only a single set of measurements for the reconstruction. The second approach is an algorithm based on linearisation which uses more then one set of measurements. A

    Full Text Available Abstract Background Chronic fatigue syndrome (CFS is a complex multifactorial disorder. This paper reports the prevalence of chronic fatigue (CF and CFS in an ethnically diverse population sample and tests whether prevalence varies by social adversity, social support, physical inactivity, anxiety and depression. Methods Analysis of survey data linking the Health Survey for England (1998 and 1999 and the Ethnic Minority Psychiatric Illness Rates in the Community (EMPIRIC study undertaken in 2000. The study population comprised a national population sample of 4,281 people ages 16 to 74 years. CF and CFS were operationally defined on the basis of an interview in the EMPIRIC study, alongside questions about psychosocial risk factors. Previous illnesses were reported in the Health Survey for England during 1998 and 1999, as was physical inactivity. Results All ethnic minority groups had a higher prevalence of CFS than the White group. The lowest prevalence was 0.8% in the White group, and it was highest at 3.5% in the Pakistani group (odds ratio (OR, 4.1; 95% confidence interval (95% CI, 1.6 to 10.4. Anxiety (OR, 1.8; 95% CI, 1.4 to 2.2, depression (OR, 1.4; 95% CI, 1.1 to 1.8, physical inactivity (OR, 2.0; 95% CI, 1.1 to 3.8, social strain (OR, 1.24; 95% CI, 1.04 to 1.48 and negative aspects of social support (OR, 2.12; 95% CI, 1.4 to 3.3 were independent risk factors for CFS in the overall sample. Together these risk factors explained ethnic differences in the prevalence of CFS, but no single risk factor could explain a higher prevalence in all ethnic groups. Conclusions The prevalence of CFS, but not CF, varies by ethnic group. Anxiety, depression, physical inactivity, social strain and negative aspects of social support together accounted for prevalence differences of CFS in the overall sample.

    2009-08-01

    Full Text Available Abstract Background Evidence for psychosocial and environmental correlates on children's physical activity is scattered and somewhat unconvincing. Further, the moderating influences of socioeconomic position (SEP on these influences are largely unexplored. The aim of this study was to examine the interactions of SEP, operationalised by mother education, and predictors of children's physical activity based on the Youth Physical Activity Promotion Model. Methods In 2005, a sample of South Australians (10–15 y was surveyed on psychosocial and environmental correlates of physical activity using the Children's Physical Activity Correlates Questionnaire (n = 3300 and a parent survey (n = 1720. The following constructs were derived: 'is it worth it?' (perceived outcomes; 'am I able?' (perceived competency; 'reinforcing' (parental support; and 'enabling' (parent-perceived barriers. Self-reported physical activity was represented by a global score derived from the Physical Activity Questionnaire for Adolescents. Associations among physical activity and hypothesised correlates were tested among children with mothers of high (university educated and low (left school at or before 15 y SEP. Results Among high SEP children, 'is it worth it?' emerged as a significant predictor of physical activity for boys and girls. Among low SEP children, 'is it worth it?' predicted boys' physical activity, while among girls, 'reinforcing' was the only significant predictor, explaining ~35% of the total explained variance in physical activity. Conclusion While perceived outcomes emerged as a consistent predictor of physical activity in this sample, parental support was a powerful limiting factor among low SEP girls. Interventions among this high risk group should focus on supporting parents to provide both emotional and instrumental support for their daughters to engage in physical activity.

    2016-07-01

    Research has shown that children in foster care are a high-risk group for adverse economic, social and health related outcomes in young adulthood. Children's poor school performance has been identified as a major risk factor for these poor later life outcomes. Aiming to support the design of effective intervention strategies, this study examines the hypothesized causal effect of foster children's poor school performance on subsequent psychosocial problems, here conceptualized as economic hardship, illicit drug use, and mental health problems, in young adulthood. Using the potential outcomes approach, longitudinal register data on more than 7500 Swedish foster children born 1973-1978 were analyzed by means of doubly robust treatment-effect estimators. The results show that poor school performance has a negative impact on later psychosocial problems net of observed background attributes and potential selection on unobservables, suggesting that the estimated effects allow for causal interpretations. Promotion of school performance may thus be a viable intervention path for policymakers and practitioners interested in improving foster children's overall life chances.

    Full Text Available Background. Musculoskeletal pain is the most common cause of incapacity among nurses. This study aimed to report the prevalence of musculoskeletal pain among hospital nurses and to explore the associations of work-related psychosocial factors and mental health problems with musculoskeletal pain. Methods. A cross-sectional survey was carried out among registered nurses at Tartu University Hospital during April and May 2011. Binary logistic regression was used to assess the associations between dependent and independent variables. Results. Analysis was based on 404 nurses (45% of the hospital’s nursing population. The overall prevalence of MSP was 70% in the past year and 64% in the past month. Lower back (57% and neck (56% were the body areas most commonly painful in the past year. Higher quantitative and emotional demands, work pace, low justice and respect in the workplace, influence on work organisation, and role conflicts were significantly associated with musculoskeletal pain among nurses (p<0.05. All mental health problems and most strongly somatic stress symptoms were associated with musculoskeletal pain. Conclusions. Work-related psychosocial risk factors and mental health problems, especially somatic stress symptoms, have an important impact on the occurrence of musculoskeletal pain among university hospital nurses.

    The transition from breast cancer patient to survivor is associated with many treatment-related and psychosocial factors, which can influence health behaviour and associated needs. First, this study aimed to identify clusters of treatment-related and psychosocial factors among breast cancer survivors. Second, clusters' physical activity levels and care needs for physical activity were evaluated. Breast cancer survivors (n= 440; 52 ± 8 years) (3 weeks to 6 months post treatment) completed self-reports on physical and psychological symptoms; illness representations; social support and coping; physical activity and care needs for physical activity. Analyses identified four clusters: (1) a low distress-active approach group; (2) a low distress-resigned approach group; (3) a high distress-active approach group; and (4) a high distress-emotional approach group. Physical activity levels were higher in the low distress groups than in the high distress-emotional approach group. However, women with low distress and an active approach reported equal care needs for physical activity than women with high distress and an emotional approach. These findings suggest that care needs for physical activity are unrelated to distress and actual physical activity levels. The results emphasise the importance of screening for needs and provide a framework supporting the referral of breast cancer survivors to tailored interventions.

    To investigate how a behavioural lifestyle intervention influences psychosocial determinants of physical activity and dietary behaviours in a population at risk of type 2 diabetes (T2DM). 59 women with a body mass index of ≥25 kg/m(2) and a history of gestational diabetes mellitus (GDM) participated in a randomized controlled study. The intervention group (n=29) received two face-to-face and five telephone lifestyle-counselling sessions with a health professional. The control group (n=30) received care as usual. At baseline and six months, psychosocial determinants related to physical activity and diet were measured with a self-administrated questionnaire. Linear regression analyses were applied to test for intervention effects. The intervention was effective in improving social support (β=3.5, p<0.001; β=2.1, p=0.02), modifying self-efficacy (β=-2.2, p=0.02; β=-4.3, p<0.001) and reducing barriers (β=-3.5, p=0.01; β=-3.8, p=0.01) for respectively physical activity and diet from baseline to six months follow-up in the intervention group compared to the control group. The intervention reduced the following barriers to a physically active lifestyle: lack of energy, and lack of motivation. Physical activity barriers like lack of time and lack of childcare were unchanged. The intervention reduced the following barriers to a healthy diet: lack of time, costs, having unhealthy snacks at home, and having cravings for sweets. This lifestyle intervention influenced psychosocial determinants relevant for overweight women with a history of GDM in prevention of T2DM.s. This article is protected by copyright.

  20. Some physics problems in biological networks

    Science.gov (United States)

    Bialek, William

    2007-03-01

    Most of the interesting things that happen in living organisms require interactions among many components, and it is convenient to think of these as a ``network'' of interactions. We use this language at the level of single molecules (the network of interactions among amino acids that determine protein structure), single cells (the network of protein-DNA interactions responsible for the regulation of gene expression) and complex multicellular organisms (the networks of neurons in our brain). In this talk I'll try to look at two very different kinds of theoretical physics problems that arise in thinking about such networks. The first problems are phenomenological: Given what our experimentalists friends can measure, can we generate a global view of network function and dynamics? I'll argue that maximum entropy methods can be useful here, and show how such methods have been used in very recent work on networks of neurons, enzymes, genes and (in disguise) amino acids. In this line of reasoning there are of course interesting connections to statistical mechanics, and we'll see that natural statistical mechanics questions about the underlying models actually teach us something about how the real biological system works, in ways that will be tested through new experiments. In the second half of the talk I'll ask if there are principles from which we might actually be able to predict the structure and dynamics of biological networks. I'll focus on optimization principles, in particular the optimization of information flow in transcriptional regulation. Even setting up these arguments forces us to think critically about our understanding of the signals, specificity and noise in these systems, all current topics of research. Although we don't know if we have the right principles, trying to work out the consequences of such optimization again suggests new experiments.

    Background. Musculoskeletal pain is the most common cause of incapacity among nurses. This study aimed to report the prevalence of musculoskeletal pain among hospital nurses and to explore the associations of work-related psychosocial factors and mental health problems with musculoskeletal pain. Methods. A cross-sectional survey was carried out among registered nurses at Tartu University Hospital during April and May 2011. Binary logistic regression was used to assess the associations between dependent and independent variables. Results. Analysis was based on 404 nurses (45% of the hospital's nursing population). The overall prevalence of MSP was 70% in the past year and 64% in the past month. Lower back (57%) and neck (56%) were the body areas most commonly painful in the past year. Higher quantitative and emotional demands, work pace, low justice and respect in the workplace, influence on work organisation, and role conflicts were significantly associated with musculoskeletal pain among nurses (p pain. Conclusions. Work-related psychosocial risk factors and mental health problems, especially somatic stress symptoms, have an important impact on the occurrence of musculoskeletal pain among university hospital nurses.

    The present study aimed to determine whether the experience of bias-motivated bullying was associated with behaviors known to increase the risk of HIV infection among young men who have sex with men (YMSM) aged 18-29, and to assess whether the psychosocial problems moderated this relationship. Using an Internet-based direct marketing approach in sampling, we recruited 545 YMSM residing in the USA to complete an online questionnaire. Multiple linear regression analyses tested three regression models where we controlled for sociodemographics. The first model indicated that bullying during high school was associated with unprotected receptive anal intercourse within the past 12 months, while the second model indicated that bullying after high school was associated with engaging in anal intercourse while under the influence of drugs or alcohol in the past 12 months. In the final regression model, our composite measure of HIV risk behavior was found to be associated with lifetime verbal harassment. None of the psychosocial problems measured in this study - depression, low self-esteem, and internalized homonegativity - moderated any of the associations between bias-motivated bullying victimization and HIV risk behaviors in our regression models. Still, these findings provide novel evidence that bullying prevention programs in schools and communities should be included in comprehensive approaches to HIV prevention among YMSM.

    Recent research highlights the importance of both job resources and personal resources in the job demands-resources model. However, the results of previous studies on how these resources are related to each other and how they operate in relation to the health-impairment process of the job demands-resources model are ambiguous. Thus, the authors tested an alternative model, considering job and personal resources to be domains of the same underlying factor and linking this factor to the health-impairment process. Survey data of two Austrian occupational samples (N 1 = 8657 and N 2 = 9536) were analyzed using confirmatory factor analysis (CFA) and structural equation modeling (SEM). The results revealed that job and personal resources can be considered as indicators of a single resources factor which was negatively related to psychosocial job demands, mental strain, and health problems. Confirming previous studies, we further found that mental strain mediated the relationship between psychosocial job demands and health problems. Our findings suggest that interventions aimed at maintaining health in the context of work may take action on three levels: (1) the prevention of extensive job demands, (2) the reduction of work-related mental strain, and (3) the strengthening of resources.

  5. The methodological problems of particle physics

    While the so-called standard model has been the dominating paradigm in particle physics for almost half a century, most researchers working with it would admit that it is an incomplete theory at best. Despite some ordering schemes, the overall number of its free parameters has greatly increased over the years, often accompanied by ad-hoc hypotheses such as 'confinement'. Experimentally, the interpretation of today's collider experiments requires sophisticated modeling of huge backgrounds. Specific problems are here how to remove correctly radiation damping (given that no consistent theory of electrodynamics exists), and postulating lifetimes (top quark) during which the particle cannot even leave the collision region. The standard model is about to develop new concepts, such as additional neutrino flavors and oscillations, while disregarding elementary questions such as to the nature of mass. From a historical perspective, the growing complications are likely to be symptoms of a scientific crisis, a phenomenon which has been described by the philosopher Thomas Kuhn. According to Kuhn however, there is no smooth transition from one paradigm to another. The only reasonable way to go beyond the standard model would be to abandon it completely.

    The aim of this study was to compare three groups of Brazilian psychoactive substance (PAS) abuse patients (crack cocaine users, cocaine snorters, and non-cocaine PAS users) in terms of psychiatric comorbidities and severity of psychosocial problems. A cross-sectional, multi-center study was conducted at five Brazilian research centers. A total of 738 current PAS abusers seeking specialized treatment (outpatient and inpatient clinics) were assessed using the sixth version of the Addiction Severity Index (ASI-6): 293 patients using crack cocaine were compared with 126 using powder cocaine and 319 using non-cocaine PAS (mostly alcohol and marijuana). Psychiatric comorbidities were assessed in a smaller sample (290 cases), originating from three of the centers, using the Mini International Neuropsychiatric Interview Plus (MINI-Plus). Crack and powder cocaine users were significantly younger than non-cocaine PAS users (31.1 ± 8.1 and 32.9 ± 8.8 vs. 42.4 ± 12, respectively; p disorder (25%) than powder cocaine (9%) and non-cocaine PAS users (9%), even when adjusted for confounding factors (Pr = 2.6; 95% CI 1.10-6.40). According to ASI-6 summary scores, crack users presented a significantly higher rate of occupational, family, and legal problems and reported more illegal and violent activities such as burglary and theft (23%) and threatening or assaulting (32%) than non-cocaine PAS users. Our findings, combined with the recent increase observed in the prevalence of crack use in Brazil, highlight the severity of psychiatric symptoms and psychosocial problems related to this powerful drug and corroborate the already suggested association between crack/cocaine, violence, and legal problems. Treatment programs for crack users should routinely consider the possibility of associated psychiatric comorbidities, such as antisocial personality disorder, which may affect treatment outcomes.

    Written questionnaires have been developed to assess children's risks of psychosocial problems based on parents' responses. However, the effectiveness of these questionnaires is limited in populations with low literacy rates, which are also among the most in need of improved mental health screening and care. The present study compared the sensitivity and specificity of a version of the Pediatric Symptom Checklist (PSC)--which contained pictorial descriptions in addition to written text--against the "gold standard" Child Behavior Checklist. We retrospectively analyzed 240 sets of questionnaires completed by the mothers or stepmothers of children who visited clinics in a Community Center in Ciudad Juarez, Mexico, between May and December 2007, under the Seguro Popular insurance program provided to Mexicans with the lowest socioeconomic status. Over 95% of the parental participants had less than a high school level of education. The pictorial PSC was a useful tool for screening for psychosocial impairment, with improved sensitivity and specificity in comparison to previous assessments of the written PSC in similar populations within the U.S. Optimal sensitivity and specificity were achieved when the threshold for clinical follow-up was lowered from 28 to 22 points. Questionnaires that include pictorial descriptions may be valuable for improvements of health screening in communities with low education levels.

    Full Text Available While symptomatic differences exist between younger and older advanced cancer patients, few studies have examined the differences in their care with respect to age. Our goals were to examine the influences of age differences on physical, psychosocial and spiritual distress among advanced cancer patients. Advanced cancer patients who resided in Kaohsiung Medical University Hospital during 2007–2008 were recruited. Data were collected through professional consultants. The influences of age variations on physical, psychosocial and spiritual distress in nonelderly (<60 years old and elderly (≧60 years old patients were analyzed. A total of 1013 advanced cancer patients were included in the analyses with 467 nonelderly patients and 546 elderly patients. Nonelderly patients were identified to have a higher baseline pain level (4.0 vs. 2.8, p<0.001, breakthrough pain (19.3% vs. 9.9%, p<0.01, insomnia (6.4% vs. 2.7%, p=0.006, emotional distress (69.0% vs. 60.6%, p=0.013, and unwillingness to pass away because of concern for loved ones (18.8% vs. 11.9%, p=0.003 with significant difference. Elderly ones were concerned about unfulfilled wishes (29.7% vs. 18.4%, p<0.001 in spiritual concerns. After adjustments in regression models, nonelderly age (<60 years old still revealed significant positive or negative impact on all categories of distress. Patients aged under 60 years have more physical, psychosocial and spiritual suffering. This study suggested that professional practitioners should provide intensive care for vulnerable terminally ill cancer patients.

    Baseline assessments and repeated measures are an essential part of educational and psychosocial intervention trials, but merely measuring an outcome of interest can modify that outcome, either by the measurement process alone or by interacting with the intervention to strengthen or weaken the intervention effects. Assessment effects can result in biased estimates of intervention effects and may not be controlled by the usual two-group randomized controlled trial design. In this paper, we review the concept of assessment effects and other related phenomena, briefly describe study designs that estimate assessment effects separately from intervention effects and discuss their strengths and limitations, review evidence regarding the strength of assessment effects in intervention trials targeting behavior change, and discuss implications for intervention research. © 2015 Wiley Periodicals, Inc.

    Osteoarthritis (OA) is a highly prevalent and disabling chronic condition. Because physical activity is a key component in OA management, effective exercise interventions are needed. Yoga is an increasingly popular multimodal mind-body exercise that aims to promote flexibility, strength, endurance, and balance. Its gentle approach is potentially a safe and effective exercise option for managing OA. The purpose of this focused review is to examine the effects of yoga on OA symptoms and physical and psychosocial outcomes. A comprehensive search was conducted using seven electronic databases. Twelve reports met inclusion criteria involving a total of 589 participants with OA-related symptoms. A variety of types, frequencies, and durations of yoga interventions were reported; Hatha and Iyengar yoga were the most commonly used types. Frequency of intervention ranged from once a week to 6 days a week. Duration of the interventions ranged from 45 to 90 mins per session for 6 to 12 wks. Yoga intervention resulted in reductions in pain, stiffness, and swelling, but results on physical function and psychosocial well-being were inconclusive because of a variety of outcome measures being used.

Results: students’ busy in their working day was analyzed as well as student’s understanding of healthy life style during working day. We also paid attention to reasons of sharp weakening of students’ physical fitness and determined integral indicator of healthy life style conception as well as significance of every its component. The following concepts are introduced: physical health, including individual level of physical condition; physical fitness and physical state. We found normal level for every component of physical health and correlation between population, regional and individual norms. Conclusions: For students’ healthy life style formation it is necessary to observe norm requirements to all its components. Violation of any component’s norm results in worsening general final result.

    The purpose of this study was to test child and adolescent psychosocial and psychopathological risk factors as predictors of adult criminal outcomes in a Swiss community sample. In particular, the role of active and avoidant problem coping in youths was analysed. Prevalence rates of young adult crime convictions based on register data were calculated. Univariate and multivariate logistic regressions were used to analyse the prediction of adult criminal convictions 15 years after assessment in a large Swiss community sample of children and adolescents (n = 1,086). Risk factors assessed in childhood and adolescence included socio-economic status (SES), migration background, perceived parental behaviour, familial and other social stressors, coping styles, externalizing and internalizing problems and drug abuse including problematic alcohol consumption. The rate of any young adult conviction was 10.1 %. Besides externalizing problems and problematic alcohol consumption, the presence of any criminal conviction in young adulthood was predicted by low SES and avoidant coping even after controlling for the effects of externalizing problems and problematic alcohol use. The other predictors were significant only when externalizing behaviours and problematic alcohol use were not controlled. In addition to child and adolescent externalizing behaviour problems and substance use, low SES and inadequate problem-solving skills, in terms of avoidant coping, are major risk factors of young adult criminal outcomes and need to be considered in forensic research and criminal prevention programs.

    Full Text Available Objective: This study analyzed the impact of psychosocial factors on pregnant women with lower back pain and an associated lack of physical activity prior to pregnancy. Methods: The sample included 66 pregnant women who were randomly selected from a total of 84 patients in the waiting rooms of the Family Health Units in Cuitegí, Paraíba, from September to November 2009. An epidemiological questionnaire adapted from the Quebec Back Pain Disability Scale was used for data collection. The questions about back pain, physical activity, and psychosocial factors were emphasized. SPSS 16.0 was used for the data analysis. The prevalence of lower back pain and its relationship to gestational age, habitual physical activity, and psychosocial factors were studied using the descriptive statistics and relative percentages in the SPSS Crosstabs procedure. The odds ratio and 95% confidence interval for lower back pain were calculated. Results: The prevalence of lower back pain was 75%, which suggests that psychosocial factors were related to the presence of pain. Anxiety was reported in 42.8% of the women with lower back pain, and 38.7% of the women with lower back pain experienced physical fatigue at the end of the day. A higher percentage of pain (53% was noted in the women who did not exercise prior to pregnancy. Conclusion: Lower back pain prior to pregnancy is associated with lack of physical activity and with psychosocial factors in the Family Health Strategy patients of Cuitegí county.

    2011-09-01

    From an original sample of 2454 participants free of self-reported psychological distress, 1463 workers completed a 15-month follow-up. Baseline measures included exposure to job demands, decision latitude, social support and need for recovery. Psychological distress was assessed using the General Health Questionnaire at baseline and at follow-up. The findings showed that medium and high exposure to job demands and social support increased the risk of reporting psychological distress at 15-months (relative risk (RR) = 1.65, 1.45). The highest adjusted RR was observed for workers reporting a high need for recovery after work (RR 2.12, 1.90) and this finding was independent of the effects of job demands, decision latitude and social support. Neither decision latitude, nor low back problems increased the risk of reporting future psychological distress, although neck problems (RR = 1.66) and hand/wrist problems (RR = 1.45) did. It was concluded that need for recovery appears to be an important indicator of individual workers who are at risk of developing psychological distress long term. STATEMENT OF RELEVANCE: This paper reports the findings of a longitudinal study showing that need for recovery from work was the strongest predictor, relative to psychosocial work characteristics (job demands, decision latitude and social support), and musculoskeletal problems, of psychological distress 15 months later in individuals initially free from distress.

    2002-09-01

    Attempts of designing economics along the lines of natural sciences (in particular, physics) with the use of mathematical modeling are reviewed. This area of research has come to be known as physical economics. Some topical questions of market economics are discussed; specifically, whether the market equilibrium is unique, whether transitions between stationary states are possible, and, if so, how these transitions proceed. By analogy with physics, the apparatus of mathematical modeling is widely used in answering these questions. It is shown that, under given external conditions, a self-sufficient country can be in two stationary, stable states — either in a high-productivity (HP) or in a low-productivity (LP) state. Transitions between them appear to be either an 'economical crisis' or an 'economical miracle'. It is shown that, for contemporary Russia, the crisis is already over, and the country is now in a stable LP state. Possible transitions to a HP state are discussed. The distributions of social elements over liquid accumulations and incomes are considered. It is shown that, in present-day Russia, these distributions are bimodal, meaning the coexistence of the poor and the wealthy with virtually no middle layer in between. In the tail of the distribution, a very small number of very wealthy people are present.

    In a companion paper, we discuss students' ability to take advantage of what they learn from a solved problem and transfer their learning to solve a quiz problem that has different surface features but the same underlying physics principles. Here, we discuss students' ability to perform analogical reasoning between another pair of problems. Both the problems can be solved using the same physics principles. However, the solved problem provided was a two- step problem (which can be solved by decomposing it into two sub-problems) while the quiz problem was a three-step problem. We find that it is challenging for students to extend what they learned from a two-step problem to solve a three-step problem.

    Full Text Available Abstract Background Adverse employment experiences, particularly exposure to unemployment and the threat of unemployment, have been strongly associated with several adverse mental and physical health outcomes including suicide. However, virtually no research has been conducted on the trans-generational impact of parental working conditions on attempted or completed suicide among their children. Methods We conducted a nested case control study based on a cohort, gathered in the western Canadian province of British Columbia, of male sawmill workers and a second cohort of their children. Physical and psychosocial work conditions to which fathers were exposed during the first 16 years of their children's lives, measured using the demand/control model, were linked to hospital suicide records (attempted and completed among their children. Results Two hundred and fifty children in the cohort attempted or committed suicide between 1985 and 2001. Multivariate models, with partial control for father's mental health outcomes prior to their child's suicide demonstrate, 1 a strong association between low duration of father's employment at a study sawmill and attempted suicide for their male children, 2 elevated odds for attempted suicide among female children of fathers' employed in a sawmill job with low control and, 3 a strong association between fathers in jobs with low psychological demand and completed suicides among male children. Conclusion Exposure of fathers to adverse psychosocial work conditions during the first 16 years of their children's life was associated with greater odds for attempted and completed suicide among their children.

  12. Key problems in black hole physics today

    CERN Document Server

    Joshi, Pankaj S

    2011-01-01

    We review here some of the major open issues and challenges in black hole physics today, and the current progress on the same. It is pointed out that to secure a concrete foundation for the basic theory as well as astrophysical applications for black hole physics, it is essential to gain a suitable insight into these questions. In particular, we discuss the recent results investigating the final fate of a massive star within the framework of the Einstein gravity, and the stability and genericity aspects of the gravitational collapse outcomes in terms of black holes and naked singularities. Recent developments such as spinning up a black hole by throwing matter into it, and physical effects near naked singularities are considered. It is pointed out that some of the new results obtained in recent years in the theory of gravitational collapse imply interesting possibilities and understanding for the theoretical advances in gravity as well as towards new astrophysical applications.

    The use of computation and simulation has become an essential part of the scientific process. Being able to transform a theory into an algorithm requires significant theoretical insight, detailed physical and mathematical understanding, and a working level of competency in programming. This upper-division text provides an unusually broad survey of the topics of modern computational physics from a multidisciplinary, computational science point of view. Its philosophy is rooted in learning by doing (assisted by many model programs), with new scientific materials as well as with the Python progr

  14. 200 more puzzling physics problems with hints and solutions

    CERN Document Server

    Gnädig, Péter; Vigh, Máté

    2016-01-01

    Like its predecessor, 200 Puzzling Physics Problems, this book is aimed at strengthening students' grasp of the laws of physics by applying them to situations that are practical, and to problems that yield more easily to intuitive insight than to brute-force methods and complex mathematics. The problems are chosen almost exclusively from classical, non-quantum physics, but are no easier for that. They are intriguingly posed in accessible non-technical language, and require readers to select an appropriate analysis framework and decide which branches of physics are involved. The general level of sophistication needed is that of the exceptional school student, the good undergraduate, or the competent graduate student; some physics professors may find some of the more difficult questions challenging. By contrast, the mathematical demands are relatively minimal, and seldom go beyond elementary calculus. This further book of physics problems is not only instructive and challenging, but also enjoyable.

    2011-12-01

    This study was conducted on 215 working women from four private corporate companies in a suburb in Malaysia to determine the factors related to their physical activity levels. Data were collected using a questionnaire which included socio-demographic characteristics, the International Physical Activity Questionnaire (IPAQ), perceived barriers and benefits to physical activity, self-efficacy to physical activity and an 8-item questionnaire on current behavioral stage of physical activity. The majority of the respondents were Malay (81.9%) with 10.2% being Chinese and 7.9% Indian. Most of the respondents were executives (64.2%), while the rest were non-executives (24.7%) and managers (11.2%). The mean weight, height, BMI and waist circumference were 59.4 +/- 13.1 kg, 1.6 +/- 0.6 m, 23.7 +/- 4.8 kg/m2 and 77.0 +/- 12.1cm respectively. In this sample, 24.7% and 7.9% were overweight and obese respectively, while 34% were at risk of abdominal obesity. A total of 28.8% of the respondents had low physical activity level, while 48.8% and 22.3% were in the moderate and high physical activity categories respectively. An association was found between monthly income (chi2 = 110.17; p 0.05). Physical activity category was also positively correlated with perceived barriers (r = 0.227, p socio-demographic and psychosocial factors (except self-efficacy to physical activity) were found to have an association with physical activity level of the respondents. Further studies should be conducted to confirm these findings in the general working women population.

  1. Divided countries, divided mind 1: psycho-social issues in adaptation problems of north korean defectors.

    Min, Sung Kil

    2008-03-01

    A review of studies on the adaptation problems of North Korean defectors in South Korean society and studies of people's adaptation to political and cultural changes in other countries suggests that similar adaptation problems may occur in the process of and after unification. Defectors have various adaptation problems and some of them have psychiatric disorders such as depression and post-traumatic stress disorder (PTSD). The reasons for this were revealed to be the difference in the culture and personality between South and North Korea, which have developed for the last 60 years without any communication with each other, in spite of their common racial and cultural heritage. Economic factors including the lack of skills and knowledge for working at industrialized and competitive society like South Korean society, also aggravate the severity of such adaptation problems. Research on defectors' adaptation problems and on the differences in the culture and mentality between North and South Korea can provide useful information on what kinds of problems may arise during the process of and after unification and what should be done to achieve mutual adaptation and harmonious and peaceful unification.

  6. The relationship of psychosocial factors to mammograms, physical activity, and fruit and vegetable consumption among sisters of breast cancer patients.

    Science.gov (United States)

    Hartman, Sheri J; Dunsiger, Shira I; Jacobsen, Paul B

    2011-01-01

    This study examined the relationship of psychosocial factors to health-promoting behaviors in sisters of breast cancer patients. One hundred and twenty sisters of breast cancer patients completed questionnaires assessing response efficacy of mammography screenings, physical activity, and fruit and vegetable consumption on decreasing breast cancer risk, breast cancer worry, involvement in their sister's cancer care, mammography screenings, physical activity, and fruit and vegetable consumption. Results indicate that greater perceived effectiveness for mammograms was associated with a 67% increase in odds of yearly mammograms. Greater involvement in the patient's care was associated with a 7% decrease in odds of yearly mammograms. Greater perceived effectiveness for physical activity was significantly related to greater physical activity. There was a trend for greater perceived effectiveness for fruits and vegetables to be associated with consuming more fruits and vegetables. Breast cancer worry was not significantly associated with the outcomes. While perceived effectiveness for a specific health behavior in reducing breast cancer risk was consistently related to engaging in that health behavior, women reported significantly lower perceived effectiveness for physical activity and fruits and vegetables than for mammograms. Making women aware of the health benefits of these behaviors may be important in promoting changes.

  7. Interpersonal circumplex descriptions of psychosocial risk factors for physical illness: application to hostility, neuroticism, and marital adjustment.

    Smith, Timothy W; Traupman, Emily K; Uchino, Bert N; Berg, Cynthia A

    2010-06-01

    Personality risk factors for physical illness are typically studied individually and apart from risk factors reflecting the social environment, potentially fostering a piecemeal understanding of psychosocial influences on health. Because it can be used to describe both personality and social relationship processes, the interpersonal circumplex (IPC) provides an integrative approach to psychosocial risk. In 301 married couples we examined IPC correlates of 3 risk factor domains: anger, hostility, and aggressiveness; neuroticism; and marital adjustment. Risk factors displayed IPC locations ranging from hostile dominance (e.g., verbal aggressiveness, marital conflict) to hostility (e.g., anger) to hostile submissiveness (e.g., anxiety, depression); protective factors (marital satisfaction and support) reflected warmth or friendliness in the IPC. Similar descriptions were found using self-reports and spouse ratings of IPC dimensions, indicating that interpersonal styles associated with risk factors do not simply reflect common method variance. Findings identify interpersonal processes reflecting low affiliation or high hostility as a common component of risk and indicate distinctions among risk factors along the dominance dimension.

  8. [Psychosocial stress and cardiology].

    Science.gov (United States)

    Houppe, Jean-Pierre

    2013-06-01

    Psychosocial stress is a major independent risk and prognostic factor of cardiovascular events. It includes psychological, sociological and socioeconomic factors. Cardiovascular diseases are important providers of psychosocial stress. The knowledge of the cerebral development throughout the time allows to a better understanding of the relationship between psychosocial stress and cardiovascular risk. Psychosocial stress leads, on top of traditional cardiovascular risk factors, to the development or to the worsening of an endothelial dysfunction, of an inflammatory response and prothrombotic phenomenon. Anxiolytics and antidepressors are not very effective against psychosocial stress. Physical activity and psychotherapy are much more indicated, particularly cognitve-behavioral therapy. The ESC recommends an evaluation of psychosocial stress through a short questionnaire.

  9. Mathematical models of physics problems (physics research and technology)

    CERN Document Server

    Anchordoqui, Luis Alfredo

    2013-01-01

    This textbook is intended to provide a foundation for a one-semester introductory course on the advanced mathematical methods that form the cornerstones of the hard sciences and engineering. The work is suitable for first year graduate or advanced undergraduate students in the fields of Physics, Astronomy and Engineering. This text therefore employs a condensed narrative sufficient to prepare graduate and advanced undergraduate students for the level of mathematics expected in more advanced graduate physics courses, without too much exposition on related but non-essential material. In contrast to the two semesters traditionally devoted to mathematical methods for physicists, the material in this book has been quite distilled, making it a suitable guide for a one-semester course. The assumption is that the student, once versed in the fundamentals, can master more esoteric aspects of these topics on his or her own if and when the need arises during the course of conducting research. The book focuses on two cor...

  10. The pursuit of evidence-based practice: Comparisons of three guidelines on psychosocial interventions for alcohol problems

    Full Text Available AIMS - In this article we scrutinise three prominent guidelines on psychosocial interventions for alcohol problems. We pay special attention to how congruent the guidelines are in terms of the interventions recommended, and the processes used in order to identify and rank the “evidence” underpinning these recommendations. DATA - The analysed guidelines are: 1 Practice Guideline for the Treatment of Patients with Substance Use Disorders, American Psychiatric Association (2006; 2 Alcohol-Use Disorders. The NICE Guideline on Diagnosis, Assessment and Management of Harmful Drinking and Alcohol Dependence (2011, National Collaborating Centre for Mental Health, UK; 3 Guidelines for the Treatment of Alcohol Problems, Australian Government, Department of Health and Ageing (2009. The purpose is not to review the three guidelines as such, but to study them as an example of the production of evidence. All report to be based on “best available evidence”, so the guidelines were compared both regarding the actual recommendations and the guideline production procedures and differences in these procedures with related consequences. RESULTS & CONCLUSIONS - Prestigious organisations in different national contexts have reached divergent conclusions about evidence-based practice and the quality of the scientific studies underpinning these conclusions. Differences in the guidelines regarding interpretations, limitations and grading illustrate the difficulties with the dilemmas of sensitivity (to include factors that are significant for how a psychological intervention is to be judged and specificity (that irrelevant studies are cleared off in the recommendations presented.

    This study aimed at analysing the association between socioeconomic status (SES) and psychosocial problems in preterm- and term-born children. Scores of mothers and teachers on the Strengths and Difficulties Questionnaire (SDQ) regarding 217 preterm-born children (preterm children (6.1 ± 4.7) than for term children (5.2 ± 4.1). After covariate adjustment, this difference was 0.5 (95 % CI 0.0-1.0). For preterm children 16.1 % of the mothers reported psychosocial problems compared with 10.1 % for term children. Lower maternal education and lower income adequacy were significantly related to higher SDQ scores of mothers and teachers. Differences in mothers' SDQ score between preterm and term children were larger in the high-education (Δ0.9, 95 % CI 0.2-1.5) and high-income group (Δ0.9, 95 % CI 0.3-1.6). No significant differences were found between preterm and term children in the SDQ scores reported by teachers. Low level of maternal education and inadequate income showed a much stronger association with psychosocial problems than preterm birth. No combined effect of low SES and preterm birth was found. This study corroborates the evidence for the strength of the disadvantageous effects of low SES on early psychosocial development.

    2016-03-01

    Cancer-related fatigue has a multidimensional nature and complaints typically increase during adjuvant treatment for breast cancer. Physical exercise might prevent or reduce cancer-related fatigue. So far, no meta-analysis has investigated the effects of physical exercise on different dimensions of fatigue. The aim of the present meta-analysis was to investigate the effects of physical exercise during adjuvant breast cancer treatment on physical and psychosocial dimensions of fatigue. We performed a systematic literature search in PubMed, Embase and the Cochrane Library in June 2015. Randomised controlled trials reporting the effects of physical exercise during adjuvant breast cancer treatment on different dimensions of fatigue were included. Pooled effects of 6 exercise programmes (including 784 patients) showed significant beneficial exercise effects on general fatigue (ES: -0.22, 95% CI -0.38; -0.05) and physical fatigue (ES: -0.35, 95% CI -0.49; -0.21). Effects on fatigue subscales 'reduced activity' (ES: -0.22, 95% CI -0.38; -0.05) and 'reduced motivation' (ES: -0.18, 95% CI -0.35; -0.01) were also in favour of physical exercise. No effects were found on cognitive and affective fatigue. Including only the supervised exercise programmes (n=4 studies), slightly larger pooled effect estimates were found on general fatigue (ES: -0.25, 95% CI -0.47; -0.04) and physical fatigue (-0.39, 95% CI -0.56; -0.23). In conclusion, physical exercise during adjuvant breast cancer treatment has beneficial effects on general fatigue, physical fatigue, 'reduced activity' and 'reduced motivation', but did not show effects on cognitive and affective fatigue. Largest effect sizes are found for physical fatigue, suggesting that this is the fatigue dimension most sensitive to physical exercise.

    Full Text Available Although, compared to boys, adolescent girls gamble less often and less problematically, prevalence studies still show significant numbers of at risk/problem gamblers among girls. However, girl gambling has been on the sidelines of adolescent gambling research. The available studies usually focus only on a narrow set of correlates often ignoring that adolescent gambling is a complex phenomenon determined by various factors. Also, they often measure gambling related consequences with instruments that are not specifically developed for use on adolescents. In order to contribute to a better understanding of adolescent gambling this study focuses on problem gambling among girls. We consider different social, cognitive, motivational and behavioral factors as predictors of girl problem gambling. A total of 1,372 high-school girls from 7 Croatian cities participated in the study. They provided data on their gambling activities, peer gambling, cognitive distortions related to gambling, motivation for gambling, and levels of general risky behavior. As the only instrument developed specifically for use on adolescents, the Canadian Adolescent Gambling Inventory was used to examine adverse gambling consequences. Results show 7.4% of girls can be considered regular gamblers, and out of those who gambled at least once in their lifetime (n = 862, 11.2% already experience mild adverse consequences because of their gambling (at risk gamblers, with 3.2% experiencing serious consequences (problem gamblers.

    1995-08-01

    The purpose of this study was to expand medical models of recovery from surgery in adolescents. Sixty-seven adolescents undergoing third molar surgery and their parents participated. Adolescents' negative affectivity, expectancies about recovery, coping styles, and parents' anticipated encouragement of illness behavior were assessed preoperatively. Extent of surgery was assessed by the oral surgeon. Outcome measures included mouth opening, disability, and pain. Extent of surgery did not predict recovery. After controlling for extent of surgery, the psychosocial parameters accounted for an additional 19% of the variance in mouth opening and 21% of the variance in disability. Adolescents' expectancies about recovery and parents' anticipated "pampering" responses predicted mouth opening. Adolescents' expectancies predicted disability. Expectancies about recovery and parental encouragement of illness behavior add predictive power to models of adolescents' recovery from surgery. Limitations of the study, future research directions, and clinical implications are discussed.

    The prevalence of job stress, distributions of major job stressors, and associations between perceived job stress levels and multiple physical discomforts are assessed via a cross-sectional study of 1023 male and female operators at telecommunication call centers in Taiwan. Cases of discomfort are identified via questionnaire surveys requiring respondents to self-reported symptoms of discomfort. Information is obtained on demographics, health status, perceived job stress levels, major job stressors and psychosocial job characteristics. Multivariate logistic regression models are developed to predict physical discomfort in nine body areas. 'Eye strain', 'hoarse or painful throat' and 'musculoskeletal discomfort' are the most pronounced and prevalent complaints after prolonged work time at call centers. Female operators had higher prevalence of physical discomfort than male operators for all body areas. 'Encountering difficult customers' ranked as the most important job stress factor among both male and female operators. Working in a call center for more than 4 years is strongly associated with discomfort in all body areas (odds ratio ranges from 1.65 to 2.15). Analysis of risk factors vs. physical discomfort reveals that operators who perceive higher job stress have significantly increased risk of several health complaints, including eye strain, tinnitus, hoarse or painful throat, chronic cough with phlegm, chest tightness, irritable stomach or peptic ulcers, frequent urination and musculoskeletal discomfort.

    This book serves as a practical guide to solving problems presented in THE PHYSICS OF RADIOLOGY, Fourth Edition. The authors contend that one does not really understand physics unless one can use it to solve problems and they have encouraged classroom problem-solving and discussion of solutions. This volume enhances that process. Approximately half of the problems found at the end of each chapter in the text have been selected with reasonable solutions provided. Solutions include, where appropriate, discussion of assumptions that may have to be made, and where the relevant formulae and data ar

    A successful childhood is to be striven after particularly for a handicapped child. Habilitation and rehabilitation, only carefully adapted to one another referring to medical specialties in colaboration with the family, may rise to the demand of the individuality of every one handicapped child. On prior conditions children with chiefly physical handicaps may be integrated into the polytechnical secondary school providing general education in the home town. The total-body examination of these children remains to be the basis for all paediatric actions.

    With the increasing focus on reducing hospital readmissions in the United States, numerous readmissions risk prediction models have been proposed, mostly developed through analyses of structured data fields in electronic medical records and administrative databases. Three areas that may have an impact on readmission but are poorly captured using structured data sources are patients' physical function, cognitive status, and psychosocial environment and support. The objective of the study was to build a discriminative model using information germane to these 3 areas to identify hospitalized patients' risk for 30-day all cause readmissions. We conducted clinician focus groups to identify language used in the clinical record regarding these 3 areas. We then created a dataset including 30,000 inpatients, 10,000 from each of 3 hospitals, and searched those records for the focus group-derived language using natural language processing. A 30-day readmission prediction model was developed on 75% of the dataset and validated on the other 25% and also on hospital specific subsets. Focus group language was aggregated into 35 variables. The final model had 16 variables, a validated C-statistic of 0.74, and was well calibrated. Subset validation of the model by hospital yielded C-statistics of 0.70-0.75. Deriving a 30-day readmission risk prediction model through identification of physical, cognitive, and psychosocial issues using natural language processing yielded a model that performs similarly to the better performing models previously published with the added advantage of being based on clinically relevant factors and also automated and scalable. Because of the clinical relevance of the variables in the model, future research may be able to test if targeting interventions to identified risks results in reductions in readmissions.

    2015-12-01

    Full Text Available Significant changes in the past year have taken place in the world of work that are bringing new challenges with regard to employee safety and health. These changes have led to emerging psychosocial risks (PSRs at work. The risks are primarily linked to how work is designed, organized, and managed, and to the economic and social frame of work. These factors have increased the level of work-related stress and can lead to serious deterioration in mental and physical health. In tackling PSRs, the European labor inspectorates can have an important role by enforcing preventive and/or corrective interventions in the content and context of work. However, to improve working conditions, unilateral interventions in the context and content of work are insufficient and require adopting a common strategy to tackle PSRs, based on a holistic approach. The implementation of a common strategy by the European Labor Inspectorate for tackling PSRs is restricted by the lack of a common legislative frame with regard to PSR evaluation and management, the different levels of labor inspectors' training, and the different levels of employees' and employers' health and safety culture.

    The problems faced by immigrants during the absorption process are multidimensional and require a systematic approach. According to the authors' theoretical perspective and clinical experience, two main principles determine the "facets" of absorption: search activity and self-esteem. The paper begins with a definition of search activity and its relationship to self-esteem and then discusses intrapsychic and environmental blocks to search activity and their effect on self-esteem. The paper concludes with a therapeutic approach toward restoration of search activity and self-esteem.

    This study sought to assess differences in attraction to physical activity, perceived physical competence and parental socialization influences across gender, body mass index and socioeconomic status in Portuguese children. Cross-sectional study. 683 children, aged 8-10 years, from elementary schools were participants. Attraction to physical activity, perceived physical competence, parental socialization influences and socioeconomic status were assessed via standardized questionnaires. The prevalence of overweight and obesity was calculated using body mass index, based on the international cut-off points. MANOVA and ANOVA models were conducted. Boys reported greater enjoyment of games and sports participation than did girls. Boys and normal-weight children perceived themselves as being more successful and physically competent than did girls and obese children. Normal-weight girls enjoyed participation in vigorous physical activity more than did overweight and obese girls. Obese children felt less accepted by their peers in games and sports than did normal-weight and overweight children. High and medium socioeconomic status children perceived physical activity participation as of greater importance than did low-socioeconomic status children. High-socioeconomic status girls reported greater liking of the exertional aspects of physical activity compared to low socioeconomic status girls. High socioeconomic status children were more likely to perceive their parents as positive role models and perceived that they had greater enjoyment of physical activity than did lower socioeconomic status children. These results suggest that physical activity promotion interventions should focus on girls, obese children and lower socioeconomic status children as these individuals tend to have lower levels of attraction to physical activity, lower perceived physical competence and less parent physical activity support, which puts them at greater risk of being physically inactive

    2016-05-01

    MAUVE (magnitude, answer, units, variables, and equations) is a framework and rubric to help students and teachers through the process of clearly solving and assessing solutions to introductory physics problems. Success in introductory physics often derives from an understanding of units, a command over dimensional analysis, and good bookkeeping. I developed MAUVE for an introductory-level environmental physics course as an easy-to-remember checklist to help students construct organized and thoughtful solutions to physics problems. Environmental physics is a core physics course for environmental and sustainability science (ESS) majors that teaches principles of radiation, thermodynamics, and mechanics within the context of the environment and sustainable energy systems. ESS student concentrations include environmental biology, applied ecology, biogeochemistry, and natural resources. The MAUVE rubric, inspired by nature, has encouraged my students to produce legible and tactical work, and has significantly clarified the grading process.

    This study investigates the belief that solving a large number of physics problems helps students better learn physics. We investigated the number of problems solved, student confidence in solving these problems, academic achievement, and the level of conceptual understanding of 49 science high school students enrolled in upper-level physics classes from Spring 2010 to Summer 2011. The participants solved an average of 2200 physics problems before entering high school. Despite having solved so many problems, no statistically significant correlation was found between the number of problems solved and academic achievement on either a mid-term or physics competition examination. In addition, no significant correlation was found between the number of physics problems solved and performance on the Force Concept Inventory (FCI). Lastly, four students were selected from the 49 participants with varying levels of experience and FCI scores for a case study. We determined that their problem solving and learning strategies was more influential in their success than the number of problems they had solved.

One hundred and twenty sisters of breast cancer patients completed questionnaires assessing response efficacy of mammography screenings, physical activity, and fruit and vegetable consumption on decreasing breast cancer risk, breast cancer worry, involvement in their sister’s cancer care, mammography screenings, physical activity, and fruit and vegetable consumption. Results indicate that greater perceived effectiveness for mammograms was associated with a 67% increase in odds of yearly mammograms. Greater involvement in the patient’s care was associated with a 7% decrease in odds of yearly mammograms. Greater perceived effectiveness for physical activity was significantly related to greater physical activity. There was a trend for greater perceived effectiveness for fruits and vegetables to be associated with consuming more fruits and vegetables. Breast cancer worry was not significantly associated with the outcomes. While perceived effectiveness for a specific health behavior in reducing breast cancer risk was consistently related to engaging in that health behavior, women reported significantly lower perceived effectiveness for physical activity and fruits and vegetables than for mammograms. Making women aware of the health benefits of these behaviors may be important in promoting changes.Keywords: breast cancer risk, mammograms, physical activity, diet, perceived effectiveness

    2015-01-01

    This study aimed to identify self-care strategies and assess physical and psychosocial factors associated with premenstrual distress among high school students. A cross-sectional survey of 217 adolescent girls aged 15 to 18 years was conducted in October 2009. Most (84.3 percent) had at least one or more symptoms of premenstrual distress. Premenstrual distress interfered with normal school activity in 51.2 percent. Most participants (57.1 percent) did not perform any self-care strategies for premenstrual distress. A hierarchical multiple linear regression analysis was conducted. Comprehension of one's own physical and mental states during premenstrual phases mediated the relationship between neuroticism and premenstrual distress. Activity restrictions due to menstrual distress mediated the relationship between the family's understanding of one's behavior during premenstrual phases and premenstrual distress. Findings suggest that, even if girls have neuroticism, it will be important to teach them to address the comprehension of one's own physical and mental states so that perceptions of both premenstruation and menstruation become more positive. Findings also suggest that the family's understanding was associated with alleviation of premenstrual distress. This study suggests the need for education to help adolescent girls and their families manage premenstrual distress and increase awareness of the benefit of managing its associated symptoms.

    Children who undertake more physical activity (PA) not only have more optimal physical health but also enjoy better mental health. However, the pathways by which PA affects well-being remain unclear. To address this question, we examined whether objectively measured daytime PA was associated with diurnal hypothalamic-pituitary-adrenocortical axis (HPAA) activity and HPAA responses to psychosocial stress. We conducted a cross-sectional study in a birth cohort in Helsinki, Finland. We studied 258 8-year-old children. PA was assessed with wrist-worn accelerometers. Overall PA and percentage of time spent in vigorous PA (VPA) were categorized by sex into thirds. Salivary cortisol was measured diurnally and in response to the Trier Social Stress Test for Children. The children in different PA groups did not show differences in diurnal salivary cortisol (P > .10 for overall PA and VPA). Children with the highest levels of overall PA or VPA showed no, or only small, increases over time in salivary cortisol after stress (P = .10 and P =.03 for time in analyses of PA and VPA, respectively), whereas children belonging to the lowest and intermediate thirds showed significant increases over time in salivary cortisol after stress (P ≤ .002 for time in the analyses of overall PA and VPA). These results suggest that children with lower levels of daytime PA have higher HPAA activity in response to stress. These findings may offer insight into the pathways of PA on physical and mental well-being.

    We followed up the psychosocial situation two years after diabetes diagnosis in patients (n = 82) aged 18-65 years, with psychosocial problems (PSP; n = 27) or not (NPSP; n = 55). We used a social questionnaire, the Hospital Anxiety and Depression scale (HAD), the Sense of Coherence scale (SOC), and the General Coping Questionnaire (GCQ). The PSP group had a more difficult situation with more strained economy, lower social support, more anxiety and depression, and lower SOC on both occasions. Being in the PSP group predicted experiencing a strong negative influence of the disease at follow-up. Regarding coping strategies, "problem focusing" decreased in both PSP and NPSP over time. "Social trust" and "intrusion" decreased only in NPSP. Otherwise the coping pattern was unchanged, with PSP showing lower scores on "self-trust" and "minimization" and higher scores on "protest," "isolation," and "intrusion." The most influenced areas at follow-up in the PSP group were work, relationship to partner and economy, and in the NPSP leisure-time activities, sexual life and work. Our findings underline the need to identify patients with psychosocial problems early.

    Salin, Denise

    2015-02-01

    Workplace bullying has been shown to be a severe social stressor at work, resulting in high costs both for the individuals and organizations concerned. The aim of this study is to analyze risk factors in a large, nationally representative sample of Finnish employees (n = 4,392). The study makes three important contributions to the existing literature on workplace bullying: first, it demonstrates the role of the physical work environment alongside the psychosocial work environment - employees with a poor physical work environment are more likely than others to report having been subjected to or having observed bullying. Second, contrary to common assumptions, the results suggest that performance-based pay is associated with a lower, rather than higher risk of bullying. Third, the findings suggest that there are gender differences in risk factors, thereby constituting a call for more studies on the role of gender when identifying risk factors. Increased knowledge of risk factors is important as it enables us to take more effective measures to decrease the risk of workplace bullying.

  18. Designing and using multiple-possibility physics problems in physics courses

    Science.gov (United States)

    Shekoyan, Vazgen

    2012-02-01

    One important aspect of physics instruction is helping students develop better problem solving expertise. Besides enhancing the content knowledge, problems help students develop different cognitive abilities and skills. This presentation focuses on multiple-possibility problems (alternatively called ill-structured problems). These problems are different from traditional ``end of chapter'' single-possibility problems. They do not have one right answer and thus the student has to examine different possibilities, assumptions and evaluate the outcomes. To solve such problems one has to engage in a cognitive monitoring called epistemic cognition. It is an important part of thinking in real life. Physicists routinely use epistemic cognition when they solve problems. I have explored the instructional value of using such problems in introductory physics courses.

  19. Reflection on problem solving in introductory and advanced physics

    Science.gov (United States)

    Mason, Andrew J.

    Reflection is essential in order to learn from problem solving. This thesis explores issues related to how reflective students are and how we can improve their capacity for reflection on problem solving. We investigate how students naturally reflect in their physics courses about problem solving and evaluate strategies that may teach them reflection as an integral component of problem-solving. Problem categorization based upon similarity of solution is a strategy to help them reflect about the deep features of the problems related to the physics principles involved. We find that there is a large overlap between the introductory and graduate students in their ability to categorize. Moreover, introductory students in the calculus-based courses performed better categorization than those in the algebra-based courses even though the categorization task is conceptual. Other investigations involved exploring if reflection could be taught as a skill on individual and group levels. Explicit self-diagnosis in recitation investigated how effectively students could diagnose their own errors on difficult problems, how much scaffolding was necessary for this purpose, and how effective transfer was to other problems employing similar principles. Difficulty in applying physical principles and difference between the self-diagnosed and transfer problems affected performance. We concluded that a sustained intervention is required to learn effective problem-solving strategies. Another study involving reflection on problem solving with peers suggests that those who reflected with peers drew more diagrams and had a larger gain from the midterm to final exam. Another study in quantum mechanics involved giving common problems in midterm and final exams and suggested that advanced students do not automatically reflect on their mistakes. Interviews revealed that even advanced students often focus mostly on exams rather than learning and building a robust knowledge structure. A survey was

    Physics problems can be represented in a number of different ways, including mathematical, graphical, pictorial, or verbal formats. In a series of studies of large-lecture introductory physics courses at the University of Colorado, we have investigated the effect of problem representation on student performance and what factors influence how students use and learn to use representations appropriately. We have found that student performance can vary strongly with representation, that giving students a choice in representational format of their physics problems can have strong effects on performance, both positive and negative, and that students in a PER-informed course may develop a broader set of representational skills than those in a traditional course.

    The following kinematics problem was given to several students as a project in conjunction with a first-semester calculus-based physics course. The students were asked to keep a journal of all their work and were encouraged to keep even their scrap paper. The goal of the project was to expose the students to the process of doing theoretical physics, by tackling a project that is easy to pose conceptually yet surprisingly challenging in its solution.

    Two large earthquakes in 2015 caused widespread destruction in Nepal. This study aimed to examine frequency of common mental health and psychosocial problems and their correlates following the earthquakes. A stratified multi-stage cluster sampling design was employed to randomly select 513 participants (aged 16 and above) from three earthquake-affected districts in Nepal: Kathmandu, Gorkha and Sindhupalchowk, 4 months after the second earthquake. Outcomes were selected based on qualitative preparatory research and included symptoms of depression and anxiety (Hopkins Symptom Checklist-25); post-traumatic stress disorder (PTSD Checklist-Civilian); hazardous alcohol use (AUDIT-C); symptoms indicating severe psychological distress (WHO-UNHCR Assessment Schedule of Serious Symptoms in Humanitarian Settings (WASSS)); suicidal ideation (Composite International Diagnostic Interview); perceived needs (Humanitarian Emergency Settings Perceived Needs Scale (HESPER)); and functional impairment (locally developed scale). A substantial percentage of participants scored above validated cut-off scores for depression (34.3%, 95% CI 28.4-40.4) and anxiety (33.8%, 95% CI 27.6-40.6). Hazardous alcohol use was reported by 20.4% (95% CI 17.1-24.3) and 10.9% (95% CI 8.8-13.5) reported suicidal ideation. Forty-two percent reported that 'distress' was a serious problem in their community. Anger that was out of control (symptom from the WASSS) was reported by 33.7% (95% CI 29.5-38.2). Fewer people had elevated rates of PTSD symptoms above a validated cut-off score (5.2%, 95% CI 3.9-6.8), and levels of functional impairment were also relatively low. Correlates of elevated symptom scores were female gender, lower caste and greater number of perceived needs. Residing in Gorkha and Sindhupalchowk districts and lower caste were also associated with greater perceived needs. Higher levels of impaired functioning were associated with greater odds of depression and anxiety symptoms; impaired

    To examine the prevalence of physical health problems among youth entering residential treatment. The sample included 1744 youth (mean age: 14.6 ± 1.8 years) entering a large residential treatment program between 2000 and 2010. Youth received an intake medical evaluation, including a review of available records, detailed medical history, and physical examination. Medical conditions present at the time of the evaluation were recorded by the examining physician and later coded by the research team. Only diagnoses recognized by the International Classification of Diseases, 10th Revision, were included in the analyses. To maintain the focus on physical health problems, behavioral and emotional disorders listed in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision were excluded. Obesity, acne, and allergies were also excluded. Approximately one-third (33.7%) of youth had a physical health diagnosis at the time of intake. Asthma was the most prevalent condition diagnosed (15.3% of the sample). Girls were significantly more likely to have a diagnosis than were boys (37.1% vs 31.5%). Age was not associated with diagnostic status. Rates of physical health conditions differed significantly by ethnicity: black (36.4%) and white (35.4%) youth had the highest rates, and Hispanic youth (23.2%) had the lowest. Youth who enter residential treatment have high rates of physical health conditions. These problems could complicate mental health treatment and should be considered in multidisciplinary treatment planning.

  8. Internet computer coaches for introductory physics problem solving

    Xu Ryan, Qing

    The ability to solve problems in a variety of contexts is becoming increasingly important in our rapidly changing technological society. Problem-solving is a complex process that is important for everyday life and crucial for learning physics. Although there is a great deal of effort to improve student problem solving skills throughout the educational system, national studies have shown that the majority of students emerge from such courses having made little progress toward developing good problem-solving skills. The Physics Education Research Group at the University of Minnesota has been developing Internet computer coaches to help students become more expert-like problem solvers. During the Fall 2011 and Spring 2013 semesters, the coaches were introduced into large sections (200+ students) of the calculus based introductory mechanics course at the University of Minnesota. This dissertation, will address the research background of the project, including the pedagogical design of the coaches and the assessment of problem solving. The methodological framework of conducting experiments will be explained. The data collected from the large-scale experimental studies will be discussed from the following aspects: the usage and usability of these coaches; the usefulness perceived by students; and the usefulness measured by final exam and problem solving rubric. It will also address the implications drawn from this study, including using this data to direct future coach design and difficulties in conducting authentic assessment of problem-solving.

    Full Text Available Abstract Background Mental disorders, common in primary care, are often associated with physical complaints. While exposure to psychosocial stressors and development or presence of principal mental disorders (i.e. depression, anxiety and somatoform disorders defined as multisomatoforme disorders is commonly correlated, temporal association remains unproven. The study explores the onset of such disorders after exposure to psychosocial stressors in a cohort of primary care patients with at least one physical symptom. Method The cohort study SODA (SOmatization, Depression and Anxiety was conducted by 21 private-practice GPs and three fellow physicians in a Swiss academic primary care centre. GPs included patients via randomized daily identifiers. Depression, anxiety or somatoform disorders were identified by the full Patient Health Questionnaire (PHQ, a validated procedure to identify mental disorders based on DSM-IV criteria. The PHQ was also used to investigate exposure to psychosocial stressors (before the index consultation and during follow up and the onset of principal mental disorders after one year of follow up. Results From November 2004 to July 2005, 1020 patients were screened for inclusion. 627 were eligible and 482 completed the PHQ one year later and were included in the analysis (77%. At one year, prevalence of principal mental disorders was 30/153 (19.6% CI95% 13.6; 26.8 for those initially exposed to a major psychosocial stressor and 26/329 (7.9% CI95% 5.2; 11.4 for those not.

    This mixed-methods, quasi-experimental pilot study examined whether the Nintendo Wii Sports (NWS) active video game (exergame) system could significantly improve the functional ability, physical activity levels, and quality of life of 34 older adults (4 men and 30 women, 83 ± 8 yr) living in 2 residential aged-care (RAC) centers. Change score analyses indicated the intervention group had significantly greater increases in bicep curl muscular endurance, physical activity levels, and psychological quality of life than the control group (p < .05). Analysis of the quotes underlying the 3 themes (feeling silly, feeling good; having fun; and something to look forward to) suggested that intervention group participants developed a sense of empowerment and achievement after some initial reluctance and anxiousness. They felt that the games were fun and provided an avenue for greater socialization. These results add some further support to the utilization of NWS exergames in the RAC context.

But how many people realize that physics can be used to produce many astonishing and strikingly elegant solutions in mathematics? Mark Levi shows how in this delightful book, treating readers to a host of entertaining problems and mind-bending puzzlers that will amuse and inspire their inner physicist. Levi turns math and physics upside down, revealing how physics can simplify proofs and lead to quicker solutions and new theorems, and how physical solutions can illustrate why results are true in ways lengthy mathematical calculations never can

    Musicians face numerous psychosocial and physical demands at work resulting in high prevalence of musculoskeletal problems. Unlike physical risks, little is known about psychosocial work factors influencing such health problems in this particular group. The paper aimed to identify psychosocial work demands resulting in musculoskeletal problems among musicians. A systematic review was undertaken to find data linking psychosocial work demands or stress with musculoskeletal disorders among musicians. The exploration of databases resulted in nine research studies linking psychosocial aspects of work or stress with musculoskeletal problems among musicians. The analyzed studies linked psychosocial aspects with musculoskeletal problems in three ways - showing proportions of people indicating particular causes of pain, indicating correlations between these variables or performing regression analysis showing psychosocial predictors of musculoskeletal pain. Only a few studies have undertaken the issue of psychosocial risk factors for musculoskeletal problems among musicians. The results revealed that some psychosocial aspects of work, e.g. long hours at work, work content, high job demands, low control/influence, lack of social support, were related to musculoskeletal pain, however, the methods and results were inconsistent. The extant studies employed variety of definitions of psychosocial aspects that hindered the possibility for consistent conclusions. Basing on those conclusions, future directions were offered.

    This article describes a general formalism for obtaining spatially localized ("sparse") solutions to a class of problems in mathematical physics, which can be recast as variational optimization problems, such as the important case of Schrödinger's equation in quantum mechanics. Sparsity is achieved by adding an regularization term to the variational principle, which is shown to yield solutions with compact support ("compressed modes"). Linear combinations of these modes approximate the eigenvalue spectrum and eigenfunctions in a systematically improvable manner, and the localization properties of compressed modes make them an attractive choice for use with efficient numerical algorithms that scale linearly with the problem size.

    No other text on the market today can match the success of Halliday, Resnick and Walker's Fundamentals of Physics. This text continues to outperform the competition year after year, and the new edition will be no exception. Intended for Calculus-based Physics courses, the 6th edition of this extraordinary text is a major redesign of the best-selling 5th edition, which still maintains many of the elements that led to its enormous success. Jearl Walker adds his unique style to this edition with the addition of new problems designed to capture, and keep, students' attention. Nearly all changes are based on suggestions from instructors and students using the 5th edition, from reviewer comments, and from research done on the process of learning. The primary goal of this text is to provide students with a solid understanding of fundamental physics concepts, and to help them apply this conceptual understanding to quantitative problem solving. The principal goal of Halliday-Resnick-Walker is to provide instructors with a tool by which they can teach students how to effectively read scientific material and successfully reason through scientific questions. To sharpen this tool, the Enhanced Problems Version of the sixth edition of Fundamentals of Physics contains over 1000 new, high-quality problems that require thought and reasoning rather than simplistic plugging of data into formulas.

    Full Text Available Our goal was to locate and evaluate the barriers that impact and cause females to avoid secondary elective physical education courses. We sought to find answers to stop the further decline of female enrolment in secondary physical education by looking into curricula, program and instructional variables. Anecdotal evidence informed this study which was very much exploratory, building upon several key facts. First, Ontario (Canada secondary students are only required to take one credit (course in physical education in order to graduate and second, most students take the required physical education course in grade nine which is their first year of high school. Following this there is an average of 10% fewer females in every physical education class in the province of Ontario and only an average of 12% are enrolled in physical education each year. Several issues were identified and explored including self-confidence; motivation; perceived value of physical activity; opportunities for physical activity; marking scheme; competition; co-ed classes; teaching approach; and peers as possible problems and solutions.

  8. A problem in particle physics and its Bayesian analysis

    Science.gov (United States)

    Landon, Joshua

    An up and coming field in contemporary nuclear and particle physics is "Lattice Quantum Chromodynamics", henceforth Lattice QCD. Indeed the 2004 Nobel Prize in Physics went to the developers of equations that describe QCD. In this dissertation, following a layperson's introduction to the structure of matter, we outline the statistical aspects of a problem in Lattice QCD faced by particle physicists, and point out the difficulties encountered by them in trying to address the problem. The difficulties stem from the fact that one is required to estimate a large -- conceptually infinite -- number of parameters based on a finite number of non-linear equations, each of which is a sum of exponential functions. We then present a plausible approach for solving the problem. Our approach is Bayesian and is driven by a computationally intensive Markov Chain Monte Carlo based solution. However, in order to invoke our approach we first look at the underlying anatomy of the problem and synthesize its essentials. These essentials reveal a pattern that can be harnessed via some assumptions, and this in turn enables us to outline a pathway towards a solution. We demonstrate the viability of our approach via simulated data, followed by its validation against real data provided to us by our physicist colleagues. Our approach yields results that in the past were not obtainable via alternate approaches. The contribution of this dissertation is two-fold. The first is a use of computationally intensive statistical technology to produce results in physics that could not be obtained using physics based techniques. Since the statistical architecture of the problem considered here can arise in other contexts as well, the second contribution of this dissertation is to indicate a plausible approach for addressing a generic class of problems wherein the number of parameters to be estimated exceeds the number of constraints, each constraint being a non-linear equation that is the sum of

Built on public-private cloud infrastructure, PR served nearly 1000 students during Fall 2012 term, delivering more than 60,000 problem pages. The service complements that of commercial publishing houses by offering problems authored by local professors and by explicitly aligning topics with exam content. We describe the service architecture, including reporting and analytical capabilities, and present an initial evaluation of the impact of its use. Among roughly 500 students studying electromagnetism, we find that the 229 students who worked fifty or more problems over the term outperformed their complement by 0.40 grade points (on a 4.0 scale). This improvement partly reflects a selection bias that academically stronger students used the service more frequently. Adjusting for this selection bias, we find a grade point improvement of 0.22, significantly above the random noise level of 0.04. The simple message to students is that working five or more additional problems per week can lead to a quarter-letter grade improvement in introductory physics. Student comments emphasize the importance of randomness in helping them to synthesize concepts. The PR source code is publicly available.

    Problem solving is a complex process valuable in everyday life and crucial for learning in the STEM fields. To support the development of problem-solving skills it is important for researchers and curriculum developers to have practical tools that can measure the difference between novice and expert problem-solving performance in authentic classroom work. It is also useful if such tools can be employed by instructors to guide their pedagogy. We describe the design, development, and testing of a simple rubric to assess written solutions to problems given in undergraduate introductory physics courses. In particular, we present evidence for the validity, reliability, and utility of the instrument. The rubric identifies five general problem-solving processes and defines the criteria to attain a score in each: organizing problem information into a Useful Description, selecting appropriate principles (Physics Approach), applying those principles to the specific conditions in the problem (Specific Application of Physics), using Mathematical Procedures appropriately, and displaying evidence of an organized reasoning pattern (Logical Progression).

    Full Text Available Abstract Background This study aimed to systematically review the evidence from randomized controlled trials (RCTs and to conduct a meta-analysis of the effects of yoga on physical and psychosocial outcomes in cancer patients and survivors. Methods A systematic literature search in ten databases was conducted in November 2011. Studies were included if they had an RCT design, focused on cancer patients or survivors, included physical postures in the yoga program, compared yoga with a non-exercise or waitlist control group, and evaluated physical and/or psychosocial outcomes. Two researchers independently rated the quality of the included RCTs, and high quality was defined as >50% of the total possible score. Effect sizes (Cohen’s d were calculated for outcomes studied in more than three studies among patients with breast cancer using means and standard deviations of post-test scores of the intervention and control groups. Results Sixteen publications of 13 RCTs met the inclusion criteria, of which one included patients with lymphomas and the others focused on patients with breast cancer. The median quality score was 67% (range: 22–89%. The included studies evaluated 23 physical and 20 psychosocial outcomes. Of the outcomes studied in more than three studies among patients with breast cancer, we found large reductions in distress, anxiety, and depression (d = −0.69 to −0.75, moderate reductions in fatigue (d = −0.51, moderate increases in general quality of life, emotional function and social function (d = 0.33 to 0.49, and a small increase in functional well-being (d = 0.31. Effects on physical function and sleep were small and not significant. Conclusion Yoga appeared to be a feasible intervention and beneficial effects on several physical and psychosocial symptoms were reported. In patients with breast cancer, effect size on functional well-being was small, and they were moderate to large for psychosocial outcomes.

    We discuss collaborative problem solving computer-based recitation style. The course is designed by Lee [1], and the idea was proposed before by Christian, Belloni and Titus [2,3]. The students find the problems on a web-page containing simulations (physlets) and they write the solutions on an accompanying worksheet after discussing it with a classmate. Physlets have the advantage of being much more like real-world problems than textbook problems. We also compare two protocols for web-based instruction using simulations in an introductory physics class [1]. The inquiry protocol allowed students to control input parameters while the worked example protocol did not. We will discuss which of the two methods is more efficient in relation to Scientific Discovery Learning and Cognitive Load Theory. 1. Lee, Kevin M., Nicoll, Gayle and Brooks, Dave W.

    Physical activity (PA) is important for controlling childhood obesity, but a comprehensive PA model for school-aged children is lacking. Guided by the youth PA promotion (YPAP) model, this study estimated the direct and indirect effects of self-efficacy, enjoyment, parental influence, and environment on self-reported PA and pedometer steps. A secondary purpose was to explore the association between self-reported PA and pedometer steps. An observational and prospective study was conducted among 133 children, aged 8-11 years old, from 10 elementary schools with afterschool programs in a Midwestern U.S. school district from August through October 2013. PA was assessed by a 7-day recall scale and pedometers. Other variables were assessed by validated questionnaires. Approximately 65 (49%) children were overweight or obese-only 17 (13%) met national PA recommendations-and body mass index z-score was negatively correlated with pedometer steps (r = -.18 p = .04). A path analysis showed that self-efficacy had a direct effect on self-reported PA and pedometer steps, enjoyment had only a direct effect on self-reported PA, and parental influence had a direct effect on pedometer steps and an indirect effect on self-reported PA through self-efficacy and enjoyment. The association between self-reported PA and pedometer steps was not significant. Because this study only partially supports the YPAP model, studies with a larger sample size and longitudinal design are essential to further examine this model. The nonsignificant relationship of self-reported PA with pedometer steps may be due to the systematic error resulting from a common method artifact of self-report. Given the importance of parental influence, enjoyment, and self-efficacy, targeting these three determinants in future interventions to increase PA among children is recommended.

    We present an `overview’ of coherence-to-decoherence transition in certain selected problems of condensed matter physics. Our treatment is based on a subsystem-plus-environment approach. All the examples chosen in this paper have one thing in common – the environmental degrees of freedom are taken to be bosonic and their spectral density of excitations is assumed to be `ohmic’. The examples are drawn from a variety of phenomena in condensed matter physics involving, for instance, quantum diffusion of hydrogen in metals, Landau diamagnetism and -axis transport in high c superconductors.

    2000-01-01

    The physics of hot plasmas is of great importance for describing many phenomena in the universe and is fundamental for the prospect of future fusion energy production on Earth. Nontrivial results of nonlinear electromagnetic effects in plasmas include the self-organization and self-formation in the plasma of structures compact in time and space. These are the consequences of competing processes of nonlinear interactions and can be best described using reaction-diffusion equations. Reaction-Diffusion Problems in the Physics of Hot Plasmas is focused on paradigmatic problems of a reaction-diffusion type met in many branches of science, concerning in particular the nonlinear interaction of electromagnetic fields with plasmas.

  20. The application of bifurcation theory to physical problems

    Science.gov (United States)

    Joseph, D. D.

    Reference is made to an observation by Lighthill (Thompson, 1982) of the one great complicating feature that introduces major difficulties into mechanics, physics, chemistry, engineering, astronomy, and biology. This is that an equilibrium can be stable but may become unstable and that a process can take place continuously but may become discontinuous. It is argued here that the complications noted by Lighthill occur even in the simplest problems. It is pointed out that a given physical system may have available many modes of operation and that the mathematical model of this system can have many solutions corresponding to the same prescribed data. In physical problems of even moderate complexity, the selection rules by which the actual realized solutions are determined are elusive. To illustrate this point, consideration is given to a simple scalar ordinary differential equation whose solution set is fully defined. It is shown that even in the simplest of problems, it is possible to have the highest degree of degeneracy with many solutions and many discontinuous changes as the control parameter is varied. Also discussed is the bifurcation of a periodic solution.

    Suicide is a prevalent problem among young people in Southern Africa, but prevention programs are largely absent. This survey aimed to identify the behavioral and psychosocial correlates of suicidal ideation among adolescents in Limpopo. A two-stage cluster sample design was used to establish a representative sample of 591 adolescents. Bivariate correlations and multiple linear regression analyses were conducted. Findings show that suicidal ideation is prevalent among adolescents. The psychosocial factors perceived social support and negative feelings about the family and the behavioral factors forced sexual intercourse and physical violence by the partner were found to increase the risk of suicidal ideation. Depression mediated the relationship between these psychosocial and behavioral risk factors and suicidal ideation. This study increased our understanding of the psychosocial and behavioral predictors of adolescent suicidal ideation. The findings provide target points for future intervention programs and call for supportive structures to assist adolescents with suicidal ideation.

    We have investigated and analyzed the cognition of an expert tackling a qualitative conceptual physics problem of an unfamiliar type. Our goal was to elucidate the detailed cognitive processes and knowledge elements involved, irrespective of final solution form, and consider implications for instruction. The basic but non-trivial problem was to find qualitatively the direction of acceleration of a pendulum bob at various stages of its motion, a problem originally studied by Reif and Allen. Methodology included interviews, introspection, retrospection and self-reported metacognition. Multiple facets of cognition were revealed, with different reasoning strategies used at different stages and for different points on the path. An account is given of the zigzag thinking paths and interplay of reasoning modes and schema elements involved. We interpret the cognitive processes in terms of theoretical concepts that emerged, namely: case-based, principle-based, experiential-intuitive and practical-heuristic reasoning; knowledge elements and schemata; activation; metacognition and epistemic framing. The complexity of cognition revealed in this case study contrasts with the tidy principle-based solutions we present to students. The pervasive role of schemata, case-based reasoning, practical heuristic strategies, and their interplay with physics principles is noteworthy, since these aspects of cognition are generally neither recognized nor taught. The schema/reasoning-mode perspective has direct application in science teaching, learning and problem-solving.

    When students make the transition from high school to college or university, their physical activity (PA) levels decrease strongly. Consequently, it is of crucial importance to identify the determinants of this decline in PA. The study aims were to (1) examine changes in psychosocial factors in students during the transition from high school to college/university, (2) examine if changes in psychosocial factors and residency can predict changes in PA, and (3) investigate the moderating effects of residency on the relationship between changes in psychosocial factors and changes in PA. Between March 2008 and October 2010, 291 Flemish students participated in a longitudinal study, with baseline measurements during the final year of high school and follow-up measurements at the start of second year of college/university. At both time points, participants completed a questionnaire assessing demographics, active transportation, leisure-time sports, psychosocial variables, and residency. Repeated measures MANOVA analyses and multiple moderated hierarchic regression analyses were conducted. Modeling, self-efficacy, competition-related benefits, and health-related, external and social barriers decreased, while health-related benefits and time-related barriers increased from baseline to follow-up. Decreases in modeling and time-related barriers were associated with a decrease in active transportation (adjusted R(2) = 3.2%); residency, decreases in self-efficacy, competition-related benefits, and increases in health- and time-related barriers predicted a decrease in leisure-time sports (adjusted R(2) = 29.3%). Residency only moderated two associations between psychosocial factors and changes in PA. Residency and changes in psychosocial factors were mainly important to explain the decrease in leisure-time sports. Other factors such as distance to college/university are likely more important to explain the decrease in active transportation; these are worth exploring in

    Full Text Available Abstract Background Depression and poor social support are significant risk factors for coronary heart disease (CHD, and stress and anxiety can trigger coronary events. People experiencing such psychosocial difficulties are more likely to be physically inactive, which is also an independent risk factor for CHD. Resilience training can target these risk factors, but there is little research evaluating the effectiveness of such programs. This paper describes the design and measures of a study to evaluate a resilience training program (READY to promote psychosocial well-being for heart health, and the added value of integrating physical activity promotion. Methods/Design In a cluster randomized trial, 95 participants will be allocated to either a waitlist or one of two intervention conditions. Both intervention conditions will receive a 10 × 2.5 hour group resilience training program (READY over 13 weeks. The program targets five protective factors identified from empirical evidence and analyzed as mediating variables: positive emotions, cognitive flexibility, social support, life meaning, and active coping. Resilience enhancement strategies reflect the six core Acceptance and Commitment Therapy processes (values, mindfulness, defusion, acceptance, self-as-context, committed action and Cognitive Behavior Therapy strategies such as relaxation training and social support building skills. Sessions include psychoeducation, discussions, experiential exercises, and home assignments. One intervention condition will include an additional session and ongoing content promoting physical activity. Measurement will occur at baseline, two weeks post intervention, and at eight weeks follow-up, and will include questionnaires, pedometer step logs, and physical and hematological measures. Primary outcome measures will include self-reported indicators of psychosocial well-being and depression. Secondary outcome measures will include self-reported indicators of

    To evaluate the impact of a physical-assessment learning experience implemented in the problem-based learning (PBL) format of the third year of a doctor of pharmacy (PharmD) program. Students enrolled in a PBL course completed survey instruments to measure knowledge and confidence before and after participating in the learning experience. A simulation stethoscope was used to teach students abnormal pulmonary and cardiovascular sounds in 1-hour sessions for each of 12 PBL groups. The 92 students enrolled in the PBL course completed pre- and post-experience survey instruments. Students' scores on knowledge questions increased significantly (p experience questions. Students scored a median of 3 or 4 on a 5-point Likert scale after a learning experience on questions measuring confidence. Use of a simulation stethoscope in a physical-assessment learning experience increased pharmacy students' knowledge in performing pulmonary and cardiovascular assessment techniques.

    2016-01-01

    The book provides a generalized theoretical technique for solving the fewbody Schrödinger equation. Straight forward approaches to solve it in terms of position vectors of constituent particles and using standard mathematical techniques become too cumbersome and inconvenient when the system contains more than two particles. The introduction of Jacobi vectors, hyperspherical variables and hyperspherical harmonics as an expansion basis is an elegant way to tackle systematically the problem of an increasing number of interacting particles. Analytic expressions for hyperspherical harmonics, appropriate symmetrisation of the wave function under exchange of identical particles and calculation of matrix elements of the interaction have been presented. Applications of this technique to various problems of physics have been discussed. In spite of straight forward generalization of the mathematical tools for increasing number of particles, the method becomes computationally difficult for more than a few particles. Hen...

  11. Exercises are problems too: implications for teaching problem-solving in introductory physics courses

    Science.gov (United States)

    Zuza, Kristina; Garmendia, Mikel; Barragués, José-Ignacio; Guisasola, Jenaro

    2016-09-01

    Frequently, in university-level general physics courses, after explaining the theory, exercises are set based on examples that illustrate the application of concepts and laws. Traditionally formulated numerical exercises are usually solved by the teacher and students through direct replacement of data in formulae. It is our contention that such strategies can lead to the superficial and erroneous resolution of such exercises. In this paper, we provide an example that illustrates that students tend to solve problems in a superficial manner, without applying fundamental problem-solving strategies such as qualitative analysis, hypothesis-forming and analysis of results, which prevents them from arriving at a correct solution. We provide evidence of the complexity of an a priori simple exercise in physics, although the theory involved may seem elementary at first sight. Our aim is to stimulate reflection among instructors to follow these results when using examples and solving exercises with students.

    Full Text Available Abstract Background Conducting process evaluations of health promoting interventions, and measuring the effectiveness of specific intervention components, may help in the understanding of program failure or success. The purposes of the present study were to examine adults' exposure to and involvement in specific components of a three year long pseudo-experimental community-based physical activity intervention, and to examine the relationship between such exposure and participation and changes in stages of change in physical activity and psychosocial mediators. Methods 1497 persons in the intervention group attended the baseline survey in 2000 (50.6% and 1204 (80.4 of baseline attendees provided data on the outcome variables of the present study. In 2003, 1089 were still living in the area, and were re-invited to follow-up assessments. Current analyses are based on the 603 persons (mean age 49 ± 10 years who provided baseline and follow-up data for the current purposes (56.6% follow-up rate. Process data, stages of change in physical activity, and potential psychosocial mediators of change in physical activity were assessed by questionnaires. The theory-based intervention was composed of communication, physical activity, environmental and participatory components. Data were analysed using frequency and descriptive statistics, Chi-square and t-tests, and regression analyses. Results Exposure and participation rates in the various intervention components varied greatly (1.5–92.7%. Participation in walking groups and aerobic exercise groups, as well as having seen the "Walk the stairs"-poster were significantly and positively related to change in stages of change in physical activity (β = .12, p = .011; β = .211, p Conclusion Findings revealed that particular intervention components, such as participation in physical activity groups, were more strongly related to forward transition in stages of change in physical activity than others.

    In the last years higher dimensional physics has won importance. Despite the Superstrings, higher dimensional effects, in measurable scales of energy (some TeV), became only possible with Randall-Sundrum's models (RS). In particular, recent studies in neutrino and axion physics have proposed new and interesting questions about neutrino mixings and new scales intermediating the Weak and Planck scales. In this work we discuss field theoretic models that in some aspects are similar to the RS models. Indeed, our models contain domain walls, solitonic-like objects that mimics the branes of the RS models. Applications are discussed ranging from topological field theories in higher dimensions until models containing D=5 space-time torsion in the RS scenario. In particular, we talk about subjects related to topological gravity, the hierarchy problem and axion physics. The topological terms studied are generalizations for $D>4$ of the axion-foton coupling in D=4. Such procedure involves naturally the Kalb-Ramond field...

    Since some 20 years most Dutch universities have one or more science shops. Central shops handle research questions for all disciplines. Specialized shops are part of a department of chemistry or medicine, history, social science, etc. The shops have evolved rather differently, but their main mission still is to help social groups that lack money and have no easy access to scientific knowledge, e.g. neighbourhood, environmental, third world or patient groups. Most also help non-commercial organizations such as schools, trade unions or local authorities. Low-cost help can be provided because students do the work as part of their training, mainly in student projects (literature search, practical work, graduation, etc.). A total staff of 80, helped by 600 students, 250 voluntary and 50 paid researchers, handle 1500 questions resulting in 300 reports (estimated figures 1995). Science shops for physics (`Physics Shop', PS) have to deal with practical problems, generally involving classical physics. Major topics are noise, vibration, radiation, indoor climate and energy: most of the work lies in estimating/measuring relevant parameters, assessing impact, seeking solutions. The 3 Dutch PS's have developed in different directions. One is run entirely by students and deals with small, concrete problems. The second PS is managed by a co-ordinator who mediates between client groups and physics staff members who assist students in small and larger projects. The third has a lot of in-house expertise, and the shop staff is in direct contact with client groups as well as students who work in the PS itself. In questions submitted to the PS it is not always immediately clear what to do or how to do it because of the non-scientific phrasing of the problems and problems include non-physical (e.g. technical, health or legal) aspects. Also, difficulties in solving the problems are typically not in the underlying physics, but in the lack of accurate data and of control of the complex

Methods Demographic, medical and psychosocial data were gathered from 4 participating outpatient pediatric diabetes clinics in the Netherlands. Ninety-one patients completed the Child Health Questionnaire-CF87 (CHQ-CF87, Centre for Epidemiological Studies scale for Depression (CES-D, and the DFCS (Diabetes-specific Family Conflict Scale. Parents completed the CHQ-PF50, CES-D and the DFCS. Results Mean age was 14.9 years (± 1.1, mean HbA1c 8.8% (± 1.7; 6.2–15.0%. Compared to healthy controls, patients scored lower on CHQ subscales role functioning-physical and general health. Parents reported less favorable scores on the behavior subscale than adolescents. Fewer diabetes-specific family conflicts were associated with better psychosocial well-being and less depressive symptoms. Living in a one-parent family, being member of an ethnic minority and reporting lower well-being were all associated with higher HbA1c values. Conclusion Overall, adolescents with type 1 diabetes report optimal well-being and parent report is in accordance with these findings. Poor glycemic control is common, with single-parent families and ethnic minorities particularly at risk. High HbA1c values are related to lower social and family functioning.

  18. Physics students' approaches to learning and cognitive processes in solving physics problems

    Bouchard, Josee

    This study examined traditional instruction and problem-based learning (PBL) approaches to teaching and the extent to which they foster the development of desirable cognitive processes, including metacognition, critical thinking, physical intuition, and problem solving among undergraduate physics students. The study also examined students' approaches to learning and their perceived role as physics students. The research took place in the context of advanced courses of electromagnetism at a Canadian research university. The cognitive science, expertise, physics and science education, instructional psychology, and discourse processes literature provided the framework and background to conceptualize and structure this study. A within-stage mixed-model design was used and a number of instruments, including a survey, observation grids, and problem sets were developed specifically for this study. A special one-week long problem-based learning (PBL) intervention was also designed. Interviews with the instructors participating in the study provided complementary data. Findings include evidence that students in general engage in metacognitive processes in the organization of their personal study time. However, this potential, including the development of other cognitive processes, might not be stimulated as much as it could in the traditional lecture instructional context. The PBL approach was deemed as more empowering for the students. An unexpected finding came from the realisation that a simple exposure to a structured exercise of problem-solving (pre-test) was sufficient to produce superior planning and solving strategies on a second exposure (post-test) even for the students who had not been exposed to any special treatment. Maturation was ruled out as a potential threat to the validity of this finding. Another promising finding appears to be that the problem-based learning (PBL) intervention tends to foster the development of cognitive competencies, particularly

    In this study, we examine introductory physics students' ability to perform analogical reasoning between two isomorphic problems which employ the same underlying physics principles but have different surface features. Three hundred and eighty two students from a calculus-based and an algebra-based introductory physics course were asked to learn from a solved problem provided and take advantage of what they learned from it to solve another isomorphic problem (which we call the quiz problem). The solved problem provided has two sub-problems while the quiz problem has three sub-problems, which is known to be challenging for introductory students from previous research. In addition to the solved problem, students also received extra scaffolding supports that were intended to help them discern and exploit the underlying similarities of the isomorphic solved and quiz problems. The results suggest that students had great difficulty in transferring what they learned from a 2-step problem to a 3-step problem. Although...

    Full Text Available Introduction: Ethiopia is experiencing an increasingly urban HIV epidemic, alongside a rise in urban adolescent migration. Adolescent migrants are often confronted by unique social challenges, including living in a difficult environment, abuse and mental health problems. These issues can increase adolescents’ vulnerability to HIV and compromise their capacity to protect themselves and others from HIV. We piloted and assessed the effects of a targeted psychosocial intervention to reduce mental health problems and improve HIV-related outcomes among migrant adolescents in Addis Ababa. Methods: A pre- and post-comparison design was used in a cohort of 576 female and 154 male migrant adolescents aged 15 to 18 years in Addis Ababa receiving services from two service delivery organizations, Biruh Tesfa and Retrak. We implemented a three-month client-centred, counsellor-delivered psychosocial intervention, based on findings from formative research among the same target population, to address participants’ increased vulnerability to HIV. The intervention package comprised individual, group and creative arts therapy counselling sessions. Key outcome indicators included anxiety, depression, aggressive behaviour, attention problems, social problems, knowledge of HIV, safer sex practices and use of sexual health services. Longitudinal data analysis (McNemar test and random effects regression was used to assess changes over time in key indicators by gender. Results: For females, aggressive behaviour decreased by 60% (adjusted odds ratio (AOR: 0.4 (0.25 to 0.65 and any mental health problem decreased by 50% (AOR: 0.5 (0.36 to 0.81 from baseline to end line. In addition, knowledge of HIV increased by 60% (AOR: 1.6 (1.08 to 2.47, knowledge of a place to test for HIV increased by 70% (AOR: 1.7 (1.12 to 2.51 and HIV testing increased by 80% (AOR: 1.8 (1.13 to 2.97. For males, HIV knowledge increased by 110% (AOR: 2.1 (1.1 to 3.94, knowledge of a place to test

    The role of psychosocial and physical work factors in predicting health related quality of life (HRQOL) has not been investigated among Iranian industrial workers. The present study is designed to assess these relationships among Iranian workers from steel and cosmetic factories. A cross-sectional study was conducted among 280 workers from two factories. Psychosocial and physical work factors and HRQOL were measured by the Persian translations of the following questionnaires: Job Content Questionnaire (JCQ) and the World Health Organization Quality of Life-Brief (WHOQOL-Brief). An instrument was developed to assess socio-demographic, health, and other work-related factors. The data were analyzed using independent t-tests, Pearson product moment correlation and hierarchical multiple regression. Results revealed that the respondents generally had poor HRQOLs especially in the environmental domain. The steel factory workers who were exposed to higher levels of occupational risk factors suffered from poorer HRQOL compared to the cosmetic factory workers. The results of hierarchical regression for all participants revealed that social support, sleep quality, work schedule, smoking and exercise were significant predictors of all domains of HRQOL. To improve the worker's HRQOL, intervention programs should focus on promoting social support, sleep quality, exercise and smoking habits. Moreover, reducing hazardous work environments should be considered an important intervention to promote HRQOL.

    The current study aims to (1) determine whether there is a relationship between the problems of patients with dementia and the psychosocial functioning of the caregiver, (2) determine whether these relationships exist independent of sociodemographic and caregiving-related variables, and (3) determine which type of problems of patients with dementia best predict the psychosocial functioning of the caregiver. In all, 73 family caregivers were recruited from Bogota, Colombia. The caregivers completed a checklist of problems presented by the person with dementia, Patient Health Questionnaire (PHQ-9), Zarit Burden Interview (ZBI), Interpersonal Support Evaluation List (ISEL-12), and Satisfaction with Life Scale (SWLS). Number of cognitive and behavioral/emotional problems presented by the person with dementia was positively correlated with caregiver PHQ-9 and ZBI scores. Number of behavioral/emotional problems was negatively correlated with ISEL-12 scores. Cognitive and behavioral/emotional problems, but not physical, presented by the person with dementia were associated with higher levels of depression and burden of caregiver. Behavioral/emotional difficulties were associated with lower caregiver-perceived social support rating.

    2012-10-01

    Full Text Available The primordial lithium problem is one of the major outstanding issues in the standard model of the Big Bang. Measurements of the baryon to photon ratio in the cosmic microwave background constrain model predictions, giving abundances of 7Li two to four times larger than observed via spectroscopic measurements of metal-poor stars. In an attempt to reconcile this discrepancy, significant effort has been directed at measuring reaction cross sections of light nuclei at astrophysically relevant energies. However, there remain reaction cross sections with large uncertainties, and some that have not yet been measured. Particularly relevant are those involving the destruction of 7Be, a progenitor of 7Li. Key issues that can be improved by nuclear physics input will be highlighted, and the applicability of detectors and event reconstruction techniques recently developed at the ANU will be discussed.

    An investigation on student understanding of waves is performed during an optional laboratory realized in informal extracurricular way with few, interested and talented pupils. The background and smart intuitions of students rendered the learning path very dynamic and ambitious. The activities started by investigating the basic properties of waves by means of a Shive wave machine. In order to make quantitative observed phenomena, the students used a camcorder and series of measures were obtained from the captured images. By checking the resulting data, it arose some learning difficulties especially in activities related to the laboratory. This experience was the starting point for a further analysis on disciplinary knots and learning problems in the physics of waves in order to elaborate a teaching-learning proposal on this topic.

    Finding a good integral representation of the reciprocal gamma function is a problem that arises naturally from a certain method of evaluating infinite sums. After finding one representation, and observing that its form is suggestive of an integral transform, we naively define one, and go on to explore its properties. While our transform as we initially define it turns out to be problematic, we demonstrate how to redefine it so that important properties (reminiscent of the Laplace and Fourier transforms) are preserved. Of particular interest is that we may transform any entire function, and that the values of the transform at the nonnegative integers correspond to the function's Taylor coefficients. We may also transform large classes of continuous and meromorphic functions. Interestingly, the aforementioned relationship between a function's transform and a function's Taylor series can be exploited to calculate analytic ``approximations'' to transformable functions. Other topics, like defining the transform for real and complex arguments, and the geometry of transformed functions, are considered. Applications to ordinary and partial differential equations, and related physical problems (from classical mechanics, electrodynamics, and quantum mechanics, among others) are discussed.

    The most of the teachers ask if there is a "best" known way to teach. The most effective teaching method depends on the specific goals of the course and the needs of the students. An investigation has been carried out to compare the effect of teaching selected physics topics using problem-solving method on the overall achievements of the acquired knowledge and teaching the same material by traditional teaching method. The investigation was performed as a pedagogical experiment of the type of parallel groups with randomly chosen sample of students attending grades eight. The control and experimental groups were equalized in the relevant pedagogical parameters. The obtained results were treated statistically. The comparison showed a significant difference in respect of the speed of acquiring knowledge, the problem-solving teaching being advantageous over traditional methodDo not replace the word "abstract," but do replace the rest of this text.

  8. Physics and Five Problems in the Philosophy of Mind

    Kauffman, Stuart

    2009-01-01

    Since Descartes' dualism, with his res extensa and res cogitans, six fundamental problems in the philosophy and natural history of mind are these: 1. how does mind act on matter? 2. If mind does not act on matter is mind a mere epiphenomenon? 3. What might be the source of free will? 4. What might be the source of a responsible free will? 5. Why might it have been selectively advantageous to evolve consciousness? 6. What is consciousness? I approach the first five of the above six problems based on two physical postulates. First the mind-brain system is a quantum coherent, but reversibly decohering and recohering system. This allows me to answer 1) above, mind does not act causally on brain at all, rather it acausally decohers to classicity (for all practical purposes), hence has consequences for brain and body as matter. Epiphenomenalism is averted. A quantum mind, because it is acausal on Copenhagen including Born, yields a free will, but a merely random free will, not a responsible free will. Second, the m...

Adolescents engaging in fighting and weapon carrying are also at risk for physical and emotional health outcomes. Involvement in fighting and weapon carrying can be seen as part of a constellation of risk behaviours with obvious health implications. Our findings also highlight the importance of the cultural context when examining the nature of violent behaviour for adolescents.

    As average life span increases, elderly will account for an increasing proportion of the total population in most parts of the world. Thus, initiatives to retain older workers at the labor market are becoming increasingly important. This study will investigate the influence of physical and psychosocial work environment throughout working life and physical and cognitive capacity in midlife on labor market attachment among older workers. Approximately 5000 participants (aged 50-60 years) from the Copenhagen Aging and Midlife Biobank (CAMB) will be followed prospectively in a national register (DREAM), containing information on a week-to-week basis about social transfer payments for about 5 million Danish residents. Using Cox regression, we will model the risk of long-term sickness absence, disability pension, early retirement and unemployment within a 4 to 6 year period from the baseline measurement as a function of the following predictors: 1) physical work demands throughout working life, 2) psychosocial working conditions throughout working life, 3) physical capacity in midlife, 4) cognitive capacity in midlife. Estimates will be adjusted for age, sex, lifestyle, socioeconomic position, chronic disease and long-term sickness absence prior to baseline. The project will generate new knowledge on risk factors for loss of labor market attachment. The results will potentially contribute in identifying factors that could be targeted in future interventions for maintaining a longer and healthier working life among older workers.

    Low levels of physical activity (PA) and highly sedentary leisure habits (SLH) in youth may establish behavioral patterns that will predispose youth to increased chronic disease risk in adulthood. The purpose of this paper was to examine associations of demographic and psychosocial factors with self-reported PA and SLH in young adolescents. A general linear mixed model predicted self-reported PA and SLH in the spring from demographic and psychosocial variables measured the previous fall in 3798 seventh grade students. PA and SLH differed by race, with Caucasian students reporting among the highest PA and lowest SLH. Perceptions of higher academic rank or expectations predicted higher PA and lower SLH. Depressive symptomatology predicted higher SLH scores but not PA. Higher self-reported value of health, appearance, and achievement predicted higher PA and lower SLH in girls. Girls who reported that their mothers had an authoritative parenting style also reported higher PA and lower SLH. Determinants of PA and SLH appear to differ from each other, particularly in boys. Development of effective programs to increase PA and/or decrease SLH in young adolescents should be based on a clear understanding of the determinants of these behaviors.

    A previous study has shown that transient physical and psychosocial activities increased the risk of developing low back pain. However, the link between these factors in triggering nonpersistent or persistent episodes remains unclear. We aimed to investigate the association of transient exposures to physical and psychosocial activities with the development of nonpersistent or persistent low back pain. This was a case-crossover study with 12 months follow-up. We included 999 consecutive participants seeking care for a sudden onset of low back pain. Development of low back pain was the outcome measure. At baseline, participants reported transient exposures to 12 predefined activities over the 4 days preceding pain onset. After 12 months, participants were asked whether they had recovered and the date of recovery. Exposures in the 2-hour period preceding pain onset (case window) were compared with the 2-hour period, 24 hours before pain onset (control window) in a case-crossover design for all participants. Conditional logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CI), and interaction analyses were used to compare estimates of nonpersistent (i.e., back pain (back pain, with ORs ranging from 2.9 to 11.7. Overall, the risk of developing a persistent or a nonpersistent episode of low back pain associated with the included physical factors did not differ significantly. Our results revealed that previously identified triggers contribute equally to the development of both nonpersistent and persistent low back pain. Future prevention strategies should focus on controlling exposure to these triggers as they have the potential to decrease the burden associated with both acute and chronic low back pain.

    Full Text Available Couple therapy is a specific practice within interpersonal relationship Psychology. Although limitations of its results must be admitted, it has demonstrated its effectiveness on an empiric way. In this article there is a short description of the concept of couple and the common problems they have. We present the couple as a social institution, in which a particular diadic relationship is established with regard to the exchange of thoughts, affection and things such as assets, the body of its members, their power relationships, their ideas about reality, their interpersonal communication, love and the capacity to problem solving, as a way out of conflicts that can emerge in their living together. We describe the contributions of communication theory and problem-solving therapy to couple therapy. 

  19. Analytical derivation: An epistemic game for solving mathematically based physics problems

    Bajracharya, Rabindra R.; Thompson, John R.

    2016-06-01

    Problem solving, which often involves multiple steps, is an integral part of physics learning and teaching. Using the perspective of the epistemic game, we documented a specific game that is commonly pursued by students while solving mathematically based physics problems: the analytical derivation game. This game involves deriving an equation through symbolic manipulations and routine mathematical operations, usually without any physical interpretation of the processes. This game often creates cognitive obstacles in students, preventing them from using alternative resources or better approaches during problem solving. We conducted hour-long, semi-structured, individual interviews with fourteen introductory physics students. Students were asked to solve four "pseudophysics" problems containing algebraic and graphical representations. The problems required the application of the fundamental theorem of calculus (FTC), which is one of the most frequently used mathematical concepts in physics problem solving. We show that the analytical derivation game is necessary, but not sufficient, to solve mathematically based physics problems, specifically those involving graphical representations.

    The study examined the effects of office space occupation, psychosocial work characteristics, and environmental satisfaction on physical and mental health of office workers in small-sized and open-plan offices as well as possible underlying mechanisms. Office space occupation was characterized as number of persons per one enclosed office space. A total of 207 office employees with similar jobs in offices with different space occupation were surveyed regarding their work situation (psychosocial work characteristics, satisfaction with privacy, acoustics, and control) and health (psychosomatic complaints, irritation, mental well-being, and work ability). Binary logistic and linear regression analyses as well as bootstrapped mediation analyses were used to determine associations and underlying mechanisms. Employee health was significantly associated with all work characteristics. Psychosocial work stressors had the strongest relation to physical and mental health (OR range: 1.66-3.72). The effect of office space occupation on employee health was mediated by stressors and environmental satisfaction, but not by psychosocial work resources. As assumed by sociotechnical approaches, a higher number of persons per enclosed office space was associated with adverse health effects. However, the strongest associations were found with psychosocial work stressors. When revising office design, a holistic approach to work (re)design is needed.

    (1) Determine the association between adolescent moderate-to-vigorous physical activity (MVPA) and screen time with their nominated friends' behaviors and (2) explore potential mechanisms of friends' social influences on MVPA and screen time. Participants consisted of 152 adolescents (mean age: 14.5 years, 53 % female, 50 % high school, 80 % Caucasian). MVPA was measured with an Actigraph GT3X+ accelerometer. Demographic and psychosocial variables were assessed via questionnaires. Participants nominated up to 5 friends who completed MVPA and screen time questionnaires. A subset of adolescents (n = 108) participated in focus groups that examined potential mechanism of friends' influence on MVPA and screen time. Multiple regression analysis examined the association of demographic, psychological, and nominated friend variables with participants' MVPA and screen time. NVivo 10.0 was used to analyze qualitative data. Greater levels of friends' MVPA was associated with greater levels of MVPA in both males (p associated with greater levels of screen time in males (p = .04) while psychosocial variables, such as increased screen time enjoyment, were associated with increased screen time in females (p = .01). School level was not associated with either MVPA or screen time. Focus group data indicated that friends positively influenced participants' MVPA through engaging in activity with participants, verbal encouragement, and modeling of MVPA. All participants preferred to be active with friends rather than alone, however, females preferred activity with a close friend while males preferred to be active with a group. Enjoyment of MVPA was the most cited reason for engaging in MVPA with friends. The majority of participants reported friends not having an influence on screen time. Adolescents with active friends are more likely to be physically active and spend less time engaging in screen-based behaviors. Interventions to increase MVPA in youth could be designed to

    2017-10-01

    Physics education research has a tradition of studying problem solving, exploring themes such as physical intuition and differences between expert and novice problem solvers. However, most of this work has focused on traditional, or well-structured, problems, similar to what might appear in a textbook. Less work has been done with open-ended, or ill-structured, problems, similar to the types of problems students might face in their professional lives. Given the national discourse on educational system reform aligned with 21st century skills, including problem solving, it is critical to provide educational experiences that help students learn to solve all types of problems, including ill-structured problems.

    Learning to solve problems is an important part of learning physics. Preparing future physics teachers to engage their students in meaningful problem solving is a part of a larger set of knowledge and skills called pedagogical content knowledge. One of the most common issues that students have when approaching physics problems is looking for the ``right formula'' instead of thinking about the concepts involved. What can we do to help students break this habit and learn to engage in expert-like problems solving? Answers to this question applied to specific areas of physics are a part of physics PCK. Workshop participants will learn how to approach problems solving with their pre-service physics teachers to help them develop problem-solving aspect of their PCK.

    Full Text Available Yoga interventions improve obesity-related outcomes including body mass index (BMI, body weight, body fat, and waist circumference, yet it is unclear whether these improvements are due to increased physical activity, increased lean muscle mass, and/or changes in eating behaviors. The purpose of this study is to expand our understanding of the experience of losing weight through yoga. Methods. Semistructured interviews were qualitatively analyzed using a descriptive phenomenological approach. Results. Two distinct groups who had lost weight through yoga responded: those who were overweight and had repeatedly struggled in their attempts to lose weight (55%, n=11 and those who were of normal weight and had lost weight unintentionally (45%, n=9. Five themes emerged that differed slightly by group: shift toward healthy eating, impact of the yoga community/yoga culture, physical changes, psychological changes, and the belief that the yoga weight loss experience was different than past weight loss experiences. Conclusions. These findings imply that yoga could offer diverse behavioral, physical, and psychosocial effects that may make it a useful tool for weight loss. Role modeling and social support provided by the yoga community may contribute to weight loss, particularly for individuals struggling to lose weight.

    Full Text Available We developed a web-based tool to provide students with access to old exam problems and solutions. By controlling the order in which students saw the problems, as well as their access to solutions, we obtained data about student learning by studying old exam problems. Our data suggest that in general students learn from doing old exam problems, and that having access to the problem solutions increases their learning. However, the data also suggest the depth of learning may be relatively shallow. In addition, the data show that doing old exam problems provides important formative assessment about the student’s overall preparedness for the exam and their particular areas of strength and weakness.

  19. Assessing Student Expertise in Introductory Physics with Isomorphic Problems, Part I: Performance on Non-intuitive Problem Pair from Introductory Physics

    CERN Document Server

    Singh, Chandralekha

    2016-01-01

    Investigations related to expertise in problem solving and ability to transfer learning from one context to another are important for developing strategies to help students perform more expert-like tasks. Here we analyze written responses to a pair of non-intuitive isomorphic problems given to introductory physics students and discussions with a subset of students about them. Students were asked to explain their reasoning for their written responses. We call the paired problems isomorphic because they require the same physics principle to solve them. However, the initial conditions are different and the frictional force is responsible for increasing the linear speed of an object in one of the problems while it is responsible for decreasing the linear speed in the other problem. We categorize student responses and evaluate student performance within the context of their evolving expertise. We compare and contrast the patterns of student categorization for the two isomorphic problems. We discuss why certain inc...

  20. Instructors’ reasons for choosing problem features in a calculus-based introductory physics course

    Directory of Open Access Journals (Sweden)

    Edit Yerushalmi

    2010-08-01

    Full Text Available This study investigates how the beliefs and values of physics faculty influence their choice of physics problems for their students in an introductory physics course. The study identifies the goals these instructors have for their students, the problem features they believe facilitate those goals, and how those features correspond to problems they choose to use in their classes. This analysis comes from an artifact-based interview of 30 physics faculty teaching introductory calculus-based physics at a wide variety of institutions. The study concludes that instructors’ goals and the problem features they believe support those goals align with research-based curricular materials intended to develop competent problem solvers. However, many of these instructors do not use the beneficial problem features because they believe these features conflict with a more powerful set of values concerned with clarity of presentation and minimizing student stress, especially on exams.

    Rebello, Carina M.; Rebello, N. Sanjay

    2012-02-01

    Previous studies have focused on the resources that students activate and utilize while solving a given physics problem. However, few studies explore how students relate a given resource such as an equation, to various types of physics problems and contexts and how they ascertain the meaning and applicability of that resource. We explore how students view physics equations, derive meaning from those equations, and use those equations in physics problem solving. We adapt Dubinsky and McDonald's description of APOS (action-process-object-schema) theory of learning in mathematics, to construct a theoretical framework that describes how students interpret and use equations in physics in terms of actions, processes, objects, and schemas. This framework provides a lens for understanding how students construct their understanding of physics concepts and their relation to equations. We highlight how APOS theory can be operationalized to serve as a lens for studying the use of mathematics in physics problem solving.

    This monograph deals with the inverse problems of determining a variable coefficient and right side for hyperbolic and parabolic equations on the basis of known solutions at fixed points of space for all times. The problems are one-dimensional in nature since the desired coefficient of the equation is a function of only one coordinate, while the desired right side is a function only of time. The authors use methods based on the spectral theory of ordinary differential operators of second order and also methods which make it possible to reduce the investigation of the inverse problems to the in

  4. Problems in classical potential theory with applications to mathematical physics

    Science.gov (United States)

    Lundberg, Erik

    In this thesis we are interested in some problems regarding harmonic functions. The topics are divided into three chapters. Chapter 2 concerns singularities developed by solutions of the Cauchy problem for a holomorphic elliptic equation, especially Laplace's equation. The principal motivation is to locate the singularities of the Schwarz potential. The results have direct applications to Laplacian growth (or the Hele-Shaw problem). Chapter 3 concerns the Dirichlet problem when the boundary is an algebraic set and the data is a polynomial or a real-analytic function. We pursue some questions related to the Khavinson-Shapiro conjecture. A main topic of interest is analytic continuability of the solution outside its natural domain. Chapter 4 concerns certain complex-valued harmonic functions and their zeros. The special cases we consider apply directly in astrophysics to the study of multiple-image gravitational lenses.

    There is evidence that overweight and obese children tend to remain overweight or obese into adolescence and adulthood. However, little is known about the long-term psychosocial outcomes of childhood overweight and obesity. This study aimed to investigate the course of psychosocial difficulties over a 2-year period for children who were overweight or obese at baseline, and a sample of children who were a healthy weight at baseline. Participants were 212 children aged 8 to 13 years at baseline, who were participating in the Childhood Growth and Development (GAD) Study. Questionnaire and interview measures were used to assess children's self-esteem, depressive symptoms, body image, eating disorder symptoms, experiences with bullying, family satisfaction and quality of life. Linear mixed models were used to consider longitudinal changes in psychosocial variables. Overweight and obese children reported greater psychosocial distress than healthy weight children, and these differences were more pronounced for girls than boys. Weight and psychosocial impairment showed stability from baseline to 2-year follow-up. The results of this study suggest that psychosocial difficulties show considerable stability in childhood, for overweight/obese and healthy weight children. What is Known: • Childhood obesity tracks into adolescence and adulthood. • Physical health problems associated with childhood obesity also persist to adulthood. What is New: • Overweight and obese children are at risk of ongoing psychosocial distress from childhood into early adolescence.

Clarity has been brought in equal measure into the the theory of physical quantities and the SI-system of units due to the basic work of Wallot and that of national and international institutions. For practical use in this paper, the most important rules and definitions for the formulation of physical equations are treated in an elementary form and the ease of their use is demonstrated in the following examples: speed of a car, capacitance of a plate capacitor, thermal emission of the cathode of an x-ray tube, oxygen uptake in cardiology, mole concentration and mass concentration of a substance in a solution. In addition, some important quantities and units of cardiology were summarized in a table.

    The inverse problem is the problem of converting detectable measurements into useful quantifiable indications. It is the problem of spectrum unfolding, image reconstruction, identifying a threat material, or devising a radiotherapy plan. The solution of an inverse problem requires a forward model that relates the quantities of interest to measurements. This paper explores the physical issues associated with formulating a radiation-transport forward model best suited for inversion, and the mathematical challenges associated with the solution of the corresponding inverse problem.

    Full Text Available Purpose: One of the methodology issues in Physical Education is providing children with safety. The purpose of this work is to present basic concepts of safety at Physical Education classes. Material & Methods: The issues connected with safety at classes of Physical Education have been discussed in the subsections, each of which focuses on different concepts such as: legal safety regulations, causes of hazards, theoretical models of preventing hazards at P.E. classes, nutrition programs related to exercise’s fulfillment, prevention of heat disorders and dehydration. Results: According to experts’ opinion, the causes of safety hazards at P.E. classes can be divided into three groups: caused by instructor, caused by a student, and finally hazards technical in nature. The number of accidents during P.E. classes is still substantial, and among most common hazards there are the following: fractures of upper and lower limbs, dislocations, contusions, tendonitis, muscle tear and cuts. Curiously, boys experience such injuries more frequently than girls. Conclusions: Even though safety rules at Physical Education classes are defined by specific regulations, children’s absolute safety is never guaranteed. In order to diminish the number of misadventures, instructor is obliged not only to adhere to the norms but also to teach children to safety rules.

  17. Effect of Scaffolding on Helping Introductory Physics Students Solve Quantitative Problems Involving Strong Alternative Conceptions

    2016-01-01

    It is well-known that introductory physics students often have alternative conceptions that are inconsistent with established physical principles and concepts. Invoking alternative conceptions in quantitative problem-solving process can derail the entire process. In order to help students solve quantitative problems involving strong alternative conceptions correctly, appropriate scaffolding support can be helpful. The goal of this study is to examine how different scaffolding supports involving analogical problem solving influence introductory physics students' performance on a target quantitative problem in a situation where many students' solution process is derailed due to alternative conceptions. Three different scaffolding supports were designed and implemented in calculus-based and algebra-based introductory physics courses to evaluate the level of scaffolding needed to help students learn from an analogical problem that is similar in the underlying principles but for which the problem solving process i...

Here, we discuss the development and validation of the survey and analysis of the student responses to the survey questions in introductory physics courses. The introductory physics students' responses to the survey questions were also compared with those of physics faculty members and physics PhD students. We find that introductory students are in general less expert-like than the physics faculty members and PhD students.

    2015-02-01

    Full Text Available Peer teaching is recognized as a powerful instructional method; however, there is a paucity of studies that have evaluated the outcomes experienced by peer-teachers and their student recipients in the context of trained, non-reciprocal, high school physical education. Accordingly, the effectiveness of a formalized and trained non-reciprocal peer teaching (T-PT program upon psychosocial, behavioral, pedagogical and student learning outcomes within high school physical education classes was investigated. Students from eight intact classes (106 males, 94 females, Mage = 12.46, SD = 0.59 were randomly assigned to either a T-PT intervention group (taught by a volunteer peer-teacher who was trained in line with a tactical games approach or untrained group (U-PT; where volunteer peer-teachers received no formal training, but did receive guidance on the game concepts to teach. Data were collected over 10 lessons in a 5-week soccer unit. Mixed-model ANOVAs/MANOVAs revealed that, in comparison to U-PT, the T-PT program significantly enhanced in-game performance actions and academic learning time among student recipients. Those in the T-PT also provided greater levels of feedback and structured learning time, as well as reporting more positive feelings about peer teaching and fewer perceived barriers to accessing learning outcomes. These findings show that non-reciprocal peer-teachers who receive formalized support through training and tactical games approach-based teaching resources can enhance behavioral, pedagogical, and motor performance outcomes in physical education.

    2012-01-01

    Full Text Available Objective. To examine physical, cognitive, and social-emotional predictors of quality of life (HRQOL and functional disability (FD in adolescents diagnosed with Neurofibromatosis-1. Methods. Participants were twenty-seven adolescents with a diagnosis of NF-1 who were recruited through an NF-1 specialty clinic at a large Midwestern children’s hospital. Measurements of the adolescents’ cognitive functioning, pain, FD, HRQOL, and social and emotional functioning were obtained with corresponding parent measures. Results. Emotional functioning significantly predicted youth-reported and parent-reported HRQOL, whereas days of pain significantly predicted youth-reported FD. Conclusions. NF-1 is a complex disease. Measurements of the overall impact of the disease tap into different aspects of the effects of NF-1 on daily life. Global outcomes such as HRQOL appear to be influenced especially by emotional functioning, whereas outcomes such as FD appear to be influenced by the physical/organic aspects of NF-1.

  11. New Concepts in Particle Physics from Solution of old Problem

    CERN Document Server

    Schrör, B

    2000-01-01

    This is a survey on recent progress in the understanding of some profound issues concerning the relation between on- and off-shell concepts in local quantum physics. Proofs for special situations have already appeared in previous publications. This present frame built on modular localization is wide enough to cover such disparate looking issues as d=1+1 factorizing theories, holographic images of QFT and scanning of higher dimensional QFT by families of chiral conformal theories. The present theory has common historical roots with the (old) string theory. But in contrast to string theory these new structures are primarily used as new tools in constructing models of local quantum particle physics i.e. they are not placed exclusively to the realm of quantum matter in curved spacetime. The new framework is within an algebraic setting of local quantum physics which de-emphasizes field-coordinatizations in favor of nets of algebras and relations between different nets, i.e. it is the same framework in which Rehren...

    Background:Studies have indicated that there is a positive and indirect relationship between physical activity (PA) and quality of life (QoL).The current study examined this relationship through a social cognitive model with consideration to the intermediary effects of exercise self-efficacy,and physical (PCS,physical component summary) and psychological (MCS,mental component summary) health.Additionally,this model was widened to include concepts from the ecological theory,and any causal associations among neighborhood environment,PA,and QoL.Methods:Six hundred and eighty-four physically active adults (39.16 ± 13.52 years,mean ± SD),living in Athens,Greece,completed a series of questionnaires measuring PA,QoL,exercise self-efficacy,PCS,MCS,neighborhood environment,and family and friend support for PA.The examined models were analyzed using structural equation modeling.Results:The social cognitive and ecological models proved to be of appropriate fit.Within the social cognitive model,PA positively affected QoL through the mediating effects of exercise self-efficacy,PCS,and MCS.With regards to the ecological model,neighborhood environment positively influenced QoL through the intermediary effects of family support for PA,exercise self-efficacy,PA,PCS,and MCS.Conclusion:Results indicated that the most important mediators in the examined models were exercise self-efficacy and health.Further,findings demonstrated the role of neighborhood environment in enhancing PA and QoL.Future studies should be carried out applying longitudinal data for a better understanding of these associations over time.

    2016-12-01

    The existing literature indicates that interactive-engagement (IE) based general physics classes improve conceptual learning relative to more traditional lecture-oriented classrooms. Very little research, however, has examined quantitative problem-solving outcomes from IE based relative to traditional lecture-based physics classes. The present study included both pre- and post-course conceptual-learning assessments and a new quantitative physics problem-solving assessment that included three representative conservation of energy problems from a first-semester calculus-based college physics course. Scores for problem translation, plan coherence, solution execution, and evaluation of solution plausibility were extracted for each problem. Over 450 students in three IE-based sections and two traditional lecture sections taught at the same university during the same semester participated. As expected, the IE-based course produced more robust gains on a Force Concept Inventory than did the lecture course. By contrast, when the full sample was considered, gains in quantitative problem solving were significantly greater for lecture than IE-based physics; when students were matched on pre-test scores, there was still no advantage for IE-based physics on gains in quantitative problem solving. Further, the association between performance on the concept inventory and quantitative problem solving was minimal. These results highlight that improved conceptual understanding does not necessarily support improved quantitative physics problem solving, and that the instructional method appears to have less bearing on gains in quantitative problem solving than does the kinds of problems emphasized in the courses and homework and the overlap of these problems to those on the assessment.

    2008-03-01

    Full Text Available In this paper, we explore the use of isomorphic problem pairs (IPPs to assess introductory physics students’ ability to solve and successfully transfer problem-solving knowledge from one context to another in mechanics. We call the paired problems “isomorphic” because they require the same physics principle to solve them. We analyze written responses and individual discussions for a range of isomorphic problems. We examine potential factors that may help or hinder transfer of problem-solving skills from one problem in a pair to the other. For some paired isomorphic problems, one context often turned out to be easier for students in that it was more often correctly solved than the other. When quantitative and conceptual questions were paired and given back to back, students who answered both questions in the IPP often performed better on the conceptual questions than those who answered the corresponding conceptual questions only. Although students often took advantage of the quantitative counterpart to answer a conceptual question of an IPP correctly, when only given the conceptual question, students seldom tried to convert it into a quantitative question, solve it, and then reason about the solution conceptually. Even in individual interviews when students who were given only conceptual questions had difficulty and the interviewer explicitly encouraged them to convert the conceptual question into the corresponding quantitative problem by choosing appropriate variables, a majority of students were reluctant and preferred to guess the answer to the conceptual question based upon their gut feeling. Misconceptions associated with friction in some problems were so robust that pairing them with isomorphic problems not involving friction did not help students discern their underlying similarities. Alternatively, from the knowledge-in-pieces perspective, the activation of the knowledge resource related to friction was so strongly and automatically

  1. A New Approach to Analyzing the Cognitive Load in Physics Problems

    Science.gov (United States)

    Teodorescu, Raluca

    2010-02-01

    I will present a Taxonomy of Introductory Physics Problems (TIPP), which relates physics problems to the cognitive processes and the knowledge required to solve them. TIPP was created for designing and clarifying educational objectives, for developing assessments to evaluate components of the problem-solving process, and for guiding curriculum design in introductory physics courses. To construct TIPP, I considered processes that have been identified either by cognitive science and expert-novice research or by direct observation of students' behavior while solving physics problems. Based on Marzano and Kendall's taxonomy [1], I developed a procedure to classify physics problems according to the cognitive processes that they involve and the knowledge to which they refer. The procedure is applicable to any physics problem and its validity and reliability have been confirmed. This algorithm was then used to build TIPP, which is a database that contains text-based and research-based physics problems and explains their relationship to cognitive processes and knowledge. TIPP has been used in the years 2006--2009 to reform the first semester of the introductory algebra-based physics course at The George Washington University. The reform targeted students' cognitive development and attitudes improvement. The methodology employed in the course involves exposing students to certain types of problems in a variety of contexts with increasing complexity. To assess the effectiveness of our approach, rubrics were created to evaluate students' problem-solving abilities and the Colorado Learning Attitudes about Science Survey (CLASS) was administered pre- and post-instruction to determine students' shift in dispositions towards learning physics. Our results show definitive gains in the areas targeted by our curricular reform.[4pt] [1] R.J. Marzano and J.S.

    1979-01-01

    Magnetospheric physics is presently in a transition from the exploratory stage to one in which satellite missions and ground-based observations are planned with the specific object of achieving a global understanding and self-consistent quantitative description of the cause-and-effect relationship among the principal dynamic processes involved. Measurements turn to lower and lower energies and to higher ion mass species, in order to encompass the entire particle population, and to a broader range of the frequency spectrum of magnetic and electric field variations. In the present paper, the current status of our knowledge on magnetospheric plasma physics is reviewed, with particular reference of such fundamental advances as the discovery of layers of streaming plasma in the magnetosphere beneath its boundary surface, the identification of the terrestrial magnetosphere as a celestial source of kilometric radiation and relativistic particles, the identification of parallel electric field regions within the magnetosphere and their role in auroral particle acceleration, and the discovery of large fluxes of energetic heavy ions trapped in the magnetosphere.

    According to the European Federation of Organizations for Medical Physics (EFOMP) policy statement No. 13, "The rapid advance in the use of highly sophisticated equipment and procedures in the medical field increasingly depends on information and communication technology. In spite of the fact that the safety and quality of such technology is vigorously tested before it is placed on the market, it often turns out that the safety and quality is not sufficient when used under hospital working conditions. To improve safety and quality for patient and users, additional safeguards and related monitoring, as well as measures to enhance quality, are required. Furthermore a large number of accidents and incidents happen every year in hospitals and as a consequence a number of patients die or are injured. Medical Physicists are well positioned to contribute towards preventing these kinds of events". The newest developments related to this increasingly important medical speciality were presented during the 8th European Conference of Medical Physics 2014 which was held in Athens, 11-13 September 2014 and hosted by the Hellenic Association of Medical Physicists (HAMP) in collaboration with the EFOMP and are summarized in this issue.

    1995-01-01

    A one-to-one and onto mapping between the set of conjunctive normal forms and a subset of the potential functions of static electric fields is given; it has been further proved that a conjunctive normal form is satisfiable if and only if there exists a zero point for its corresponding potential function. A particle is always moving in the direction of gradient descent in the field which is the fastest decreasing direction of potential of the particle. Thus, if a conjunctive normal form is satisfiable, the gradient method for its corresponding potential function becomes a fast algorithm to solve its satisfiability problem.

    Szita, Bernadett; Baji, Ildikó; Rigó, János

    2015-12-13

    Distress conditions during pregnancy may contribute to the development of preeclampsia by altering functions of the neuroendocrine and immune systems, e.g. activation of the hypothalamic-pituitary-adrenal axis and increase in plasma proinflammatory cytokines. Preeclampsia may also precipitate mental health problems due to long-term hospitalization or unpredictable and uncontrollable events such as preterm labor and newborn complications. Besides, preeclampsia may induce persistent neurocognitive complaints with a negative impact on patients' quality of life. As growing evidence indicates that poor maternal mental health has an adverse effect on pregnancy outcome and fetal development, psychosocial interventions may be beneficial for women with preeclampsia.

  6. THE PROCESS OF SEPARATION AND INDIVIDUATION AS THE RISK FACTOR IN PSYCHOSOCIAL DEVELOPMENT OF PERSONS WITH PHYSICAL DISABILITIES

    Directory of Open Access Journals (Sweden)

    Simona OZHEK

    2007-05-01

    Full Text Available The process of separation and individuation is a developmental psychological process, which takes place at various phases of child development within his first three years of life. These phases include the Normal Autistic Phase, the Normal Symbiotic Phase, the Separation-Individuation Phase (with sub-phases Differentiation, Practicing and Rapprochement, On the Way to Object Con­stancy and the Final Separation and Psychological Birth of the Human Infant. Undisturbed transition through the developmental phases leads to the es­tablishment of psychological structure in the hu­man infant, which means that he reaches autonomy and independence, thus becoming an individual. For children which were born with physical dis­abilities and have their intellectual capacities pre­served (i.e. in cerebral palsy, muscular dystrophy etc., the fulfillment of this process is endangered, because their development was stuck at the Nor­mal Symbiotic Phase due to two types of factors. The first group represents factors of physical dis­ability (i.e. impossibility to move, obtain inde­pendent experiences and, consequently, the inabil­ity to detach from the Object, while the second group represents reactions to this hindrance (i.e. over-protection, which further thwarts attempts to detach from the Object.

    The pathways by which physical activity impacts on participants' health are still not fully understood. The purpose of the present study was to go beyond existing research by combining methods from survey-based and experimental stress research, and by examining whether the potential of vigorous physical activity (VPA) to attenuate physiological and psychological stress responses is moderated by participants' subjective stress perception. The sample consisted of 42 undergraduate students (M=21.2±2.2 years, 52% women). Participants self-reported their stress and wore an accelerometer device for seven consecutive days. To examine differences in the adrenocortical, autonomic and psychological stress reactivity, salivary free cortisol, heart rate, state anxiety, mood and calmness were assessed prior to, during and after the Trier Social Stress Test (TSST). The cut-offs of the American College of Sports Medicine (ACSM) were used to distinguish between students below/above current VPA recommendations. High levels of perceived stress combined with VPA levels below the ACSM's standards (strategy to increase physiological and psychological stress resilience. Copyright © 2017 Elsevier Ltd.

  9. Temporal and spatial analysis in knowledge-based physics problem-solving

    Science.gov (United States)

    Lee, Xiang-Seng

    Physics problems as stated in textbooks are typically informal and incomplete, and not amenable to the direct application of the general laws of physics. A theory of analysis for automatically solving such problems is presented. In particular, the theory provides a detailed methodology for constructing a formal problem representation, called physical representation, upon which physics laws may be appropriately selected and instantiated. With the equations generated by these laws, the solutions to these problems are obtained through strictly mathematical manipulations. This theory provides a well-structured domain language, in which it is relatively easy to state mechanical knowledge and mechanics problems. In the language the notion of basic physical phenomenon for representing the knowledge of physical situations and events is introduced. This notion serves as both the building block for the physical representation and as a vehicle for accessing the appropriate physical laws. Both basic physical phenomena and more traditional temporal entities, instants, and intervals may be used as time references. This dual-system representation facilitates bi-level abstractions of time necessary to avoid discontinuities introduced by short impulsive phenomena, e.g., collisions, and corresponds well with human-like temporal reasoning. The language also includes an ontology of space, using multiple abstractions to account for its inherent complexity, and representation schemes for physical laws and equations. The other key ingredient of the theory is a repertoire of ordered knowledge sources, formulated to specify the derivation procedures of a physical representation. The domain language, in which these knowledge sources are written, has a structure which is useful as a theoretical basis for determining their ordering and inference step sizes. This practice has proven crucial for building knowledge-based systems that are easy to debug and modify. The theory was implemented and

    Dar, A. [Technion-Israel Inst. of Tech., Haifa (Israel). Dept. of Physics

    1996-11-01

    The {sup 8}B solar neutrino flux predicted by the standard solar model (SSM) is consistent within the theoretical and experimental uncertainties with that at Kamiokande. The Gallium and Chlorine solar neutrino experiments, however, seem to imply that the {sup 7}Be solar neutrino flux is strongly suppressed compared with that predicted by the SSM. If the {sup 7}Be solar neutrino flux is suppressed, still it can be due to astrophysical effects not included in the simplistic SSM. Such effects include short term fluctuations or periodic variation of the temperature in the solar core, rotational mixing of {sup 3}He in the solar core, and dense plasma effects which may strongly enhance p-capture by {sup 7}Be relative to e-capture. The new generation of solar observations which already look non stop deep into the sun, like Superkamiokande through neutrinos, and SOHO and GONG through acoustic waves, may point at the correct solution. Only Superkamiokande and/or future solar neutrino experiments, such as SNO, BOREXINO and HELLAZ, will be able to find out whether the solar neutrino problem is caused by neutrino properties beyond the minimal standard electroweak model or whether it is just a problem of the too simplistic standard solar model.

    Ten years ago we started to develop a Collection of Fully Solved Problems aimed at introductory undergraduate and high school level students. The collection is specially designed to encourage students in an active approach to problem solving, e.g. to solve at least some parts of a problem on their own. Nowadays the Collection contains about 800 fully solved problems in physics in Czech and nearly 180 problems in English. It has several hundreds of unique visitors per school day. Based on user feedback, the collection is used by students mainly for their home study and by teachers as a supplementary material. The creation of the structured solution of the physics problems has proved to be a beneficial activity for prospective physics teachers (students of our department).

    'Patient Reported Outcomes Following Initial treatment and Long term Evaluation of Survivorship (PROFILES)' is a registry for the study of the physical and psychosocial impact of cancer and its treatment from a dynamic, growing population-based cohort of both short and long-term cancer survivors. PROFILES contains a large web-based component and are linked directly to clinical data from the population-based Eindhoven cancer registry. This paper describes the rationale and design of PROFILES. The primary aims of studies that use the PROFILES registry are: (1) psychosocial risk and outcome assessment to identify patients at high risk for poor physical and mental health outcomes, (2) to analyse mediating mechanisms to better understand the biological and behavioural factors associated with cancer treatment outcomes, and (3) to evaluate physical and psychosocial care needs of cancer survivors. PROFILES is a tool that enables data collection management; from inviting patients to participation in studies, to collecting patient-reported outcomes data via web-based or mailed questionnaires and linking these data with clinical data. The availability of a control cohort of approximately 2000 persons from the general population who complete the same basic questionnaire annually will provide the opportunity to estimate the unique impact of cancer, beyond that of normal ageing and comorbidities. Raw data from the PROFILES registry will be available for non-commercial scientific research, subject to study question, privacy and confidentiality restrictions, and registration (www.profilesregistry.nl).

The application of these theories and plasma supply to pulsars is discussed, with attention given to the total amount of electron-positron plasma created and its momentum distribution. Various aspects of radiation emission and transport are analyzed, based on a polar current flow model with pair creation, and the phenomenon of marching subpulses is considered. The coronation beaming and the relativistically expanding current sheet models for pulsar emission are also outlined, and the paper concludes with a brief discussion of the relation between the theories of polar flow with pair plasma and the problem of the energization of the Crab Nebula.

  18. Psychosocial Accompaniment

    Directory of Open Access Journals (Sweden)

    Mary Watkins

    2015-08-01

    Full Text Available This essay advocates for a paradigm shift in psychology toward the activity and ethics of accompaniment. Accompaniment requires a reorientation of the subjectivity, interpersonal practices, and critical understanding of the accompanier so that (she can stand alongside others who desire listening, witnessing, advocacy, space to develop critical inquiry and research, and joint imagination and action to address desired and needed changes. The idea of “accompaniment” emerged in liberation theology in Latin America, and migrated into liberatory forms of psychology as “psychosocial accompaniment.” This essay explores accompaniment and its ethics from a phenomenological perspective, highlighting differences from mainstream stances in psychology. Attention is also given to the effects of accompaniment on the accompanier. Efforts to decolonize psychology require careful attention to the psychic decolonization of its practitioners and to the cultivation of decolonizing interpersonal practices that provide a relational and ethical foundation for joint research, restorative healing, and transformative action. Such practices endeavor through dialogue to build mutual respect and understanding, promote effective solidarity, and contribute to the empowerment of those marginalized. The decolonization of psychology should enable practitioners to be more effective in working for increased social, economic, and environmental justice; peace building and reconciliation; and local and global ecological sustainability.

    Maries, Alex

    2016-01-01

    Drawing appropriate diagrams is a useful problem solving heuristic that can transform a given problem into a representation that is easier to exploit for solving it. A major focus while helping introductory physics students learn problem solving is to help them appreciate that drawing diagrams facilitates problem solution. We conducted an investigation in which 111 students in an algebra-based introductory physics course were subjected to two different interventions during recitation quizzes throughout the semester. They were either (1) asked to solve problems in which the diagrams were drawn for them or (2) explicitly told to draw a diagram. A comparison group was not given any instruction regarding diagrams. We developed a rubric to score the problem-solving performance of students in different intervention groups. Here, we present some surprising results for problems which involve considerations of initial and final conditions.

  1. Demographic, Physiologic, and Psychosocial Correlates of Physical Activity in Structured Exercise and Sports Among Low-Income, Overweight Children.

    2015-01-01

    To describe correlates of physical activity (PA) in structured exercise and structured sports sessions among low-income, overweight children participating in a community-based PA program. A total of 93 children (55% male; 91% Hispanic) aged 8-14 years were included. Participants wore pedometers in a sample of 10 of 59 total sessions offered; mean steps per minute were calculated for structured exercise and sports sessions. Separate multivariable regression models tested associations between steps per minute in exercise and sports sessions and 5 potential correlates: baseline body mass index z-score, aerobic fitness (Progressive Aerobic Cardiorespiratory Endurance Run laps), perceived athletic competence (Harter self-perception profile), sex, and age. Only age (ß = -2.9; P = .02) significantly predicted steps per minute in exercise sessions. Age (ß = -4.3; P = .007), fitness (ß = 0.45; P = .03), and male sex (ß = 8.7; P = .02) significantly predicted steps per minute in sports. In structured exercise and sports, perceived competence may not influence overweight and obese children's PA. However, girls and older or less fit children may engage less actively, especially in sports. Copyright © 2015 Society for Nutrition Education and Behavior. Published by Elsevier Inc.

    2016-01-01

    The ability to categorize problems based upon underlying principles, rather than contexts, is considered a hallmark of expertise in physics problem solving. With inspiration from a classic study by Chi, Feltovich, and Glaser, we compared the categorization of 25 introductory mechanics problems based upon similarity of solution by students in large calculus-based introductory courses with physics faculty and Ph.D. students. Here, we summarize the study and suggest that a categorization task, especially when conducted with students working with peers in small groups, can be an effective pedagogical tool to help students in introductory physics courses learn to discern the underlying similarity between problems with diverse contexts but the same underlying physics principles.

  4. Time Does Not Help Orangutans Pongo abelii Solve Physical Problems

    2017-01-01

    Many questions in animal intelligence and cognition research are challenging. One challenge is to identify mechanisms underlying reasoning in experiments. Here, we provide a way to design such tests in non-human animals. We know from research in skill acquisition in humans that reasoning and thinking can take time because some problems are processed in multiple steps before a solution is reached (e.g., during mental arithmetics). If animals are able to learn through similar processes their decision making can be time consuming, and most importantly improve if more time to process information is allowed. We tested if performance of two Sumatran orangutans (Pongo abelii) increased in a two-choice experiment when they were allowed extra time before making their decisions, compared to when they were forced to decide immediately. We found that the performance of the orangutans did not depend on the time they were allowed to process the information before making their decisions. This methodology provides a potential avenue for empirical tests of mechanisms underlying reasoning in non-human animals. PMID:28223959

    The purpose of this study was to examine the impact of participation in different sport modalities on quality of life (QOL) and perceived social competence (PSC) in young people with physical disability. Ninety participants (33 females and 57 males) were monitored across four conditions: competitive separate physical activity (COSPA), recreational separate physical activity (RESPA), reverse-integrated basketball activity (RIBA), and no physical activity (NOPA). QOL and PSC questionnaires were administered at the beginning and the end of the study's duration of six months. ANCOVA corrected for functional independence and gender revealed significant group effects for pre to post change values of QOL and PSC, with greater positive change in the RIBA compared to all other groups. In addition, one-way ANOVA on pre to post change values with LSD post hoc revealed significant differences. RIBA change values for QOL with 8.77%, and for PSC with 9.98% change were significantly higher (p<.001) than in all other groups (ranges -0.18 through 1.36% for QOL, and -2.31 through 2.34% for PSC). These outcomes demonstrate a favorable outcome of the RIBA on participants. Low functional ability did not constrain the effects of sport participation.

    Previously we discussed how well students in an introductory physics course diagnosed their mistakes on a quiz problem with different levels of scaffolding support. In that case, the problem they self-diagnosed was unusually difficult. We also discussed issues related to transfer, particularly the fact that the transfer problem in the midterm that corresponded to the self-diagnosed problem was a far transfer problem. Here, we discuss a related intervention in which we repeated the study methodology with the same students in the same intervention groups, using a new quiz problem which was more typical for these students and a near transfer problem. We discuss how these changes affected students' ability to self-diagnose and transfer from the self-diagnosed quiz problem to a transfer problem on the midterm exam.

  8. Statistical physics approaches to understanding the firm growth problem

    Science.gov (United States)

    Fu, Dongfeng

    This thesis applies statistical physics approaches to investigate quantitatively the size and growth of the complex system of business firms. We study the logarithm of the one-year growth rate of firms g ≡ log(S(t + 1)/S( t)) where S(t) and S( t + 1) are the sizes of firms in the year t and t + 1 measured in monetary values. Part I in this thesis reviews some main empirical results of firm size and firm growth based on different databases. They are (i) the size distribution of firms P(S) are found to be skewed (either log-normal or power-law depending on the different databases), (ii) the growth-rate distributions of firms P(g) are of Laplace form with power-law tails, (iii) the standard deviation of firm growth rates is related by a negative power-law to the firm size. The distribution of firm growth rates conditioned on firm size collapses onto a single curve, which implies that a universal functional form may exist to describe the distribution of firm growth rate. Part II models the Entry & Exit effect and firm proportional growth using a generalized preferential attachment model. The model assumes that a new firm enters the system with a constant rate; a new unit enters/exits one of existing firms preferentially, that it, the larger firms have bigger probability to obtain the new unit, and the larger firms have bigger probability to lose a unit. The model successfully explains the observations: (i) the distribution of unit number P( K) in a firm is power law with exponential tails, (ii) P (g) is of Laplace form with power-law tails with exponent 3. Part III studies the Merging & Splitting effect in the framework of Coase theory using a dynamic percolation model in a 2-dimensional lattice where each row represents a product and each column can represent a consumer; a cell is a potential transaction. The size of the firm would be represented by the number of the cells it covers in the lattice. The model explains the facts that P(S) is power-law, P(g) is tent

  9. Differences in visual attention between those who correctly and incorrectly answer physics problems

    Full Text Available This study investigated how visual attention differed between those who correctly versus incorrectly answered introductory physics problems. We recorded eye movements of 24 individuals on six different conceptual physics problems where the necessary information to solve the problem was contained in a diagram. The problems also contained areas consistent with a novicelike response and areas of high perceptual salience. Participants ranged from those who had only taken one high school physics course to those who had completed a Physics Ph.D. We found that participants who answered correctly spent a higher percentage of time looking at the relevant areas of the diagram, and those who answered incorrectly spent a higher percentage of time looking in areas of the diagram consistent with a novicelike answer. Thus, when solving physics problems, top-down processing plays a key role in guiding visual selective attention either to thematically relevant areas or novicelike areas depending on the accuracy of a student’s physics knowledge. This result has implications for the use of visual cues to redirect individuals’ attention to relevant portions of the diagrams and may potentially influence the way they reason about these problems.

It was determined that the males’ physical activity values (3822.85 MET- min./week, were higher compared to those of the females (2103.17. On the contrary, the problem solving skills of the males (mean 2.91 were lower than those of the females (mean 2.95. The SPSS 23.0 for Windows program was used in the statistical analyses of the data. In order to see if the data distributed normally or not, Tabachnick and Fidell coefficients were used for the kurtosis and skewness values. For the comparison of the problem solving skills scores and the physical activity scores, the t test statistical method was used. In conclusion, no significant relationship at p<0.05 level was determined between the students’ problem solving skills and their physical activity states.

    Full Text Available Background: Disasters have adverse impacts on different aspects of human life. Psychosocial Rehabilitation is one of the fields which is usually overshadowed and ignored by physical rehabilitation or its importance does not receive proper attention. This research attempts to study some lessons learned from Psychosocial Rehabilitation based on disaster experiences in Iran. Materials and Methods: This study has a conventional qualitative content analysis design. The participants of study were 15 people with direct experience of earthquake and 12 experts in this field. The study sample was selected by purposeful sampling method and the data were collected by semi-structured interviews. Results: Lack of a suitable system to deliver Psychosocial Rehabilitation, challenge in establishing balance between short-term and long-term social and mental needs, lack of mental and social experts, inefficiency in using social capital and capacities are the most important lessons learned in this field. Conclusion: Lack of awareness of mental and social problems of affected people after disaster is one of the most important barriers in successful and stable rehabilitation. Psychosocial Rehabilitation requires a suitable structure and planning for all stages of disaster management.

  12. Behavioural treatments for sleep problems in children and adolescents with physical illness, psychological problems or intellectual disabilities.

    Young people with physical, psychological or intellectual disabilities or disorders are reported to have more frequent and persistent problems with sleep than their peers without . Sleep disorders affecting the quantity or quality of sleep have effects on a child's daytime functioning and the functioning of their families. Many children with special needs have learning and behaviour problems and their parents (particularly mothers) have increased levels of stress and poorer mental health. This relationship between sleep disorders and learning, and behaviour and family functioning makes it particularly important that children with special needs receive appropriate intervention for their sleep disorders. This may be one way of mitigating these other problems. This review considers the case reports and experimental trials which have used behavioural treatments for sleep problems in children and adolescents with special needs. Behavioural treatments for sleep-wake cycle disorders, sleeplessness, parasomnias and excessive sleepiness are reported. These preliminary reports do suggest that behavioural approaches can be rapidly successful for treating sleep problems, even where the sleep problems are long-standing, severe and associated with physical, psychological or intellectual problems. The parent and the clinician should not be deterred from treating the sleep problem in isolation using behavioural treatments. Methodological issues, however, highlight the importance of further and better research. Not all children responded to the behavioural interventions and some needed re-implementation of therapy to maintain improvements; the use of heterogeneous groups make the findings and choice of treatment for individuals difficult to interpret. Finally, there are few studies overall, and the majority are case studies rather than controlled studies using multiple baseline designs or randomization and a control group. Careful studies are required in order to establish the

  19. Effect of scaffolding on helping introductory physics students solve quantitative problems involving strong alternative conceptions

    Science.gov (United States)

    Lin, Shih-Yin; Singh, Chandralekha

    2015-12-01

    It is well known that introductory physics students often have alternative conceptions that are inconsistent with established physical principles and concepts. Invoking alternative conceptions in the quantitative problem-solving process can derail the entire process. In order to help students solve quantitative problems involving strong alternative conceptions correctly, appropriate scaffolding support can be helpful. The goal of this study is to examine how different scaffolding supports involving analogical problem-solving influence introductory physics students' performance on a target quantitative problem in a situation where many students' solution process is derailed due to alternative conceptions. Three different scaffolding supports were designed and implemented in calculus-based and algebra-based introductory physics courses involving 410 students to evaluate the level of scaffolding needed to help students learn from an analogical problem that is similar in the underlying principles involved but for which the problem-solving process is not derailed by alternative conceptions. We found that for the quantitative problem involving strong alternative conceptions, simply guiding students to work through the solution of the analogical problem first was not enough to help most students discern the similarity between the two problems. However, if additional scaffolding supports that directly helped students examine and repair their knowledge elements involving alternative conceptions were provided, e.g., by guiding students to contemplate related issues and asking them to solve the targeted problem on their own first before learning from the analogical problem provided, students were more likely to discern the underlying similarities between the problems and avoid getting derailed by alternative conceptions when solving the targeted problem. We also found that some scaffolding supports were more effective in the calculus-based course than in the algebra

    Before reporting the preliminary results obtained by our group, we first review the main problems to be solved in the preservation of organs at very low temperature, before being transplanted. This cryopreservation is being presently explored in order to increase the preservation tiine of transplants and to contribute to a better control of the donor recipient compatibility. We recall that, for the isolated cells to be preserved at nitrogen liquid temperatures, as now successfully performed at industrial scale, it is necessary to immerse the cells in a solution containing more or less t,oxical additives (so-called cryopro tect ants). Furthermore cooling and warming rates must be specific of each type of cells. We then show that cryo preservation could be extrapolated to whole organs by means of vitrification, the only way to avoid any ice crystallization. This vitrification will be the result of two directions of research, the one on the elaboration of cryoprotective solutions, the least toxic possible, the other on the obtention of high enough and homogeneous cooling and warming rates. After having briefly summarized the state of research on the heart and kidneys of small mammals, we present the first results that we have obtained on perfusion at 4 ^{circ}C and the auto-transplantation of rabbit kidneys, on the toxicity of a new cryoprotectant, 2,3-butanediol, on the heart rate, and on the cooling of experimental models of organs. Avant de présenter les résultats préliminaires obtenus par notre groupe, nous passons d'abord en revue les principaux problèmes à résoudre pour conserver à très basse température des organes en vue de leur transplantation. Cette cryopréservation est une voie de recherche actuellement explorée pour augmenter la durée de conservation des greffons et permettre ainsi de mieux contrôler la compatibilité donneur-receveur. Nous rappelons que la conservation des cellules isolées à la température de l'azote liquide, actuellement
