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).

People with intellectual disabilities face a much greater burden and earlier onset of physical and mental ill-health than the general adult population. Physical-mental comorbidity has been shown to result in poorer outcomes in the general population, but little is known about this relationship in adults with intellectual disabilities. To identify whether physical ill-health is associated with mental ill-health in adults with intellectual disabilities and whether the extent of physical multi-morbidity can predict the likelihood of mental ill-health. To identify any associations between types of physical ill-health and mental ill-health. A total of 1023 adults with intellectual disabilities underwent comprehensive health assessments. Binary logistic regressions were undertaken to establish any association between the independent variables: total number of physical health conditions, physical conditions by International Classification of Disease-10 chapter and specific physical health conditions; and the dependent variables: problem behaviours, mental disorders of any type. All regressions were adjusted for age, gender, level of intellectual disabilities, living arrangements, neighbourhood deprivation and Down syndrome. The extent of physical multi-morbidity was not associated with mental ill-health in adults with intellectual disabilities as only 0.8% of the sample had no physical conditions. Endocrine disease increased the risk of problem behaviours [odds ratio (OR): 1.22, 95% confidence interval (CI): 1.02-1.47], respiratory disease reduced the risk of problem behaviours (OR: 0.73, 95% CI: 0.54-0.99) and mental ill-health of any type (OR: 0.73, 95% CI: 0.58-0.92), and musculoskeletal disease reduced the risk of mental ill-health of any type (OR: 0.84, 95% CI: 0.73-0.98). Ischaemic heart disease increased the risk of problem behaviours approximately threefold (OR: 3.29, 95% CI: 1.02-10.60). The extent of physical multi-morbidity in the population with intellectual

Anti-psychotic medication has emerged as the primary medical treatment for people with severe mental illness, despite the great risks involved in the use of this medication. In addition, this population suffers from problems of obesity, sedentary lifestyle and poor physical fitness, which is aggravated by the use of this type of medication. The objective of this study is to explore the influence of the most commonly used antipsychotics in this population (Olanzapine and Risperidone) on physical activity and the physical fitness of people with severe mental illness. Sixty-two people between 26 and 61 years of age with severe mental illness were assessed. All participants were evaluated with a battery of 11 physical tests to assess their physical fitness and with the IPAQ-short version questionnaire to determine their level of physical activity. The doses of Risperidone and Olanzapine were also evaluated in all participants. Significant differences were found for physical activity, with higher levels reported in those patients with severe mental illness who did not take any of these medications. Regarding physical fitness, significant differences were only found for the consumption of Risperidone, with better physical fitness levels seen in patients who did not consume this medication; on the other hand, for the consumption of Olanzapine, differences were found in muscular strength, balance and aerobic condition with better values in non-Olanzapine consumers compared with Olanzapine consumers.

Full Text Available The Centers for Disease Control currently report cervical, vulvar, vaginal, anal and some head and neck cancers as human papillomavirus (HPV-associated cancers. Only cervical cancer is listed amongst acquired immunodeficiency syndrome (AIDS defining illnesses. All of these cancers may represent progression of the immunocompromised state with the inability to eradicate viral infection. This study reports the case of a 27-year old HIV positive female presenting with a persistent right vulvar exophytic lesion. High-risk HPV analysis and immunostaining for P16 were both positive. A biopsy of the lesion revealed invasive squamous cell carcinoma. The patient underwent neoadjuvant radiation and chemotherapy followed by a radical vulvectomy. During treatment, her CD4 T-lymphocyte count decreased to 120 advancing her condition from HIV to AIDS. This case suggests that all HPV-associated cancers should be included as AIDS defining illnesses.

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.

Psychosocial distress among patients with limited life expectancy influences treatment decisions, treatment adherence, and physical health. Veterans may be at elevated risk of psychosocial distress at the end of life, and understanding their mental healthcare needs may help identify hospitalized patients to whom psychiatric services should be targeted. To examine mental illness prevalence and mental health treatment rates among a national sample of hospitalized veterans with serious physical illnesses. Design, Subjects, and Measurements: This was a retrospective study of 11,286 veterans hospitalized in a Veterans Health Administration acute care facility in fiscal year 2011 with diagnoses of advanced cancer, congestive heart failure, chronic obstructive pulmonary disease, and/or advanced HIV/AIDS. Prevalent and incident mental illness diagnoses during and before hospitalization and rates of psychotherapy and psychotropic use among patients with incident depression and anxiety were measured. At least one-quarter of the patients in our sample had a mental illness or substance use disorder. The most common diagnoses at hospitalization were depression (11.4%), followed by alcohol abuse or dependence (5.5%), and post-traumatic stress disorder (4.9%). Of the 831 patients with incident past-year depression and 258 with incident past-year anxiety, nearly two-thirds received at least some psychotherapy or guideline-concordant medication within 90 days of diagnosis. Of 191 patients with incident depression and 47 with incident anxiety at time of hospitalization, fewer than half received mental healthcare before discharge. Many veterans hospitalized with serious physical illnesses have comorbid mental illnesses and may benefit from depression and anxiety treatment.

This study is a preliminary research aiming at exploring pre-service physics teachers’ skills in applying the stage of problem-solving strategies. A total of 76 students of physics education study program at a college in Bengkulu Indonesia participated in the study. The skills on solving physics problems are being explored through exercises that demand the use of problem-solving strategies with several stages such as useful description, physics approach, specific application of physics, physics equation, mathematical procedures, and logical progression. Based on the results of data analysis, it is found that the pre-service physics teachers’ skills are in the moderate category for physics approach and mathematical procedural, and low category for the others. It was concluded that the pre-service physics teachers’ problem-solving skills are categorized low. It is caused by the learning of physics that has done less to practice problem-solving skills. The problems provided are only routine and poorly trained in the implementation of problem-solving strategies.The results of the research can be used as a reference for the importance of the development of physics learning based on higher order thinking skills.

2015-01-01

Comorbid physical health conditions, commonly associated with mental illness, contribute to increased morbidity and reduced life expectancy. The trajectory to poorer health begins with the onset of mental illness. For young people with mental illness, health risk behaviours and poor physical health can progress to adulthood with long-term detrimental impacts. Using a cross-sectional survey design, self-reported health risk behaviours were gathered from 56 young (16-25 years) Australians who had been hospitalised for mental illness and taking psychotropic medication. Smoking, alcohol use, minimal physical activity, and lack of primary health care were evident. While these behaviours are typical of many young people, those with mental illness have substantially increased vulnerability to poor health and reduced life expectancy. Priority needs to be given to targeted health promotion strategies for young people with mental illness to modify their risky long-term health behaviours and improve morbidity and mortality outcomes. Nurses in mental health settings play a vital role in promoting young peoples' well-being and preventing poorer physical health outcomes. Implementation of a cardiometabolic health nurse role in inpatient settings for young people with mental illness could facilitate prevention and early intervention for health risk behaviours.

Using Analogy to Solve a Three-Step Physics Problem

2010-10-01

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.

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.

Perez-Cruzado, David; Cuesta-Vargas, Antonio I; Vera-Garcia, Elisa; Mayoral-Cleries, Fermín

2017-01-01

Physical fitness is a crucial variable in people with severe mental illness as these people could be more independent and improve their job opportunities. The present study compared the physical fitness of physically active and inactive people with severe mental illness. Physical fitness was evaluated in sixty-two people with severe mental illness using 11 physical tests that include strength, flexibility, balance and aerobic condition. Significant differences were found between both groups in muscle strength (handgrip test) and balance (single leg balance test and functional reach) with better performance in the group of physically active people. The results of the present study suggest that physical fitness (strength and balance) is higher in people with severe mental illness who practise regular physical activity that those who are inactive people. Physical active people may have a reduced risk of falls and fractures due to their higher levels of physical fitness.

This study examined the ways in which individuals over 50 years old solved problems while volunteering in intensive humanitarian and disaster relief service. Thirty-seven men and women in the sample were sponsored by three religious organizations well known for providing humanitarian and disaster relief service. Semistructured interviews yielded data that were analyzed qualitatively, using McCracken's five-step process for analysis. We found that volunteers used three different abilities to solve problems: drawing upon experience to create strategies, maintaining emotional stability in the midst of trying circumstances, and applying strategies in a context-sensitive manner. These findings illustrate that these factors, which are comparable to those used in solving everyday problems, are unique in the way they are applied to intensive volunteering. The volunteers' sharing of knowledge, experience, and support with each other were also noticeable in their accounts of their service. This sharing contributed strongly to their sense of emotional stability and effectiveness in solving problems. © The Author(s) 2015.

Numerous factors influence late-life depressive symptoms in adults, many not thoroughly characterized. We addressed whether genetic and environmental influences on depressive symptoms differed by age, sex, and physical illness. The analysis sample included 24 436 twins aged 40-90 years drawn from the Interplay of Genes and Environment across Multiple Studies (IGEMS) Consortium. Biometric analyses tested age, sex, and physical illness moderation of genetic and environmental variance in depressive symptoms. Women reported greater depressive symptoms than men. After age 60, there was an accelerating increase in depressive symptom scores with age, but this did not appreciably affect genetic and environmental variances. Overlap in genetic influences between physical illness and depressive symptoms was greater in men than in women. Additionally, in men extent of overlap was greater with worse physical illness (the genetic correlation ranged from near 0.00 for the least physical illness to nearly 0.60 with physical illness 2 s.d. above the mean). For men and women, the same environmental factors that influenced depressive symptoms also influenced physical illness. Findings suggested that genetic factors play a larger part in the association between depressive symptoms and physical illness for men than for women. For both sexes, across all ages, physical illness may similarly trigger social and health limitations that contribute to depressive symptoms.

The life expectancy of adults with mental illness is worse than that of the general population and is largely due to poor physical health status. Physical activity has been consistently recommended for the prevention and management of many chronic physical health conditions and can also have benefits for mental health. This cross sectional study assessed the attitudes towards and preferences for physical activity among inpatient adults with mental illness, and differences by distress and gender. Self-report questionnaires were completed by 101 patients. Findings indicated that inpatient adults with mental illness are interested in doing physical activity while in hospital, primarily to maintain good physical health and improve emotional wellbeing. Fewer than half of participants agreed that physical activity has benefits for serious mental illness. Participants indicated a preference for walking and physical activity that can be done alone, at a fixed time and with a set routine and format. Major barriers were fatigue and lack of motivation. Females were more likely than males to prefer activities done with others of the same gender (P = 0.001) and at the same level of ability (P physical activity intervention programming in hospital settings, which may contribute to decreasing the chronic disease burden and improve the psychological wellbeing in adults with mental illness. © 2015 Australian College of Mental Health Nurses Inc.

How does mental-physical multimorbidity express itself in lived time and space? A phenomenological analysis of encounters with depression and chronic physical illness.

Coventry, Peter A; Dickens, Chris; Todd, Chris

2014-10-01

Mental-physical multimorbidity (the co-existence of mental and physical ill health) is highly prevalent and associated with significant impairments and high healthcare costs. While the sociology of chronic illness has developed a mature discourse on coping with long term physical illness the impact of mental and physical health have remained analytically separated, highlighting the need for a better understanding of the day-to-day complexities encountered by people living with mental-physical multimorbidity. We used the phenomenological paradigm of the lived body to elucidate how the experience of mental-physical multimorbidity shapes people's lifeworlds. Nineteen people with chronic obstructive pulmonary disease (COPD) and depression (defined as a score ≥8 on depression scale of Hospital Anxiety and Depression Scale) were recruited from secondary NHS care and interviewed at their homes. Data were analysed phenomenologically using van Manen's lifeworld existential framework of the lived body, lived time, lived space, lived relations. Additionally, we re-analysed data (using the same framework) collected from 13 people recruited from secondary NHS care with either COPD, rheumatoid arthritis, heart disease, or type 1 or type 2 diabetes and depression. The phenomenology of mental-physical multimorbidity was articulated through embodied and emotional encounters with day-to-day life in four ways: [a] participants' perception of lived time and lived space contracted; [b] time and [c] space were experienced as liminal categories, enforcing negative mood and temporal and spatial contraction; and [d] time and space could also be customised to reinstate agency and self-determination. Mental-physical multimorbidity negatively impacts on individuals' perceptions of lived time and lived space, leading to a loss of agency, heightened uncertainty, and poor well-being. Harnessing people's capacity to modify their experience of time and space may be a novel way to support people

Ethical controversy surrounds clinical research involving seriously ill participants. While many stakeholders have opinions, the extent to which protocol volunteers themselves see human research as ethically acceptable has not been documented. To address this gap of knowledge, authors sought to assess views of healthy and ill clinical research volunteers regarding the ethical acceptability of human studies involving individuals who are ill or are potentially vulnerable. Surveys and semi-structured interviews were used to query clinical research protocol participants and a comparison group of healthy individuals. A total of 179 respondents participated in this study: 150 in protocols (60 mentally ill, 43 physically ill, and 47 healthy clinical research protocol participants) and 29 healthy individuals not enrolled in protocols. Main outcome measures included responses regarding ethical acceptability of clinical research when it presents significant burdens and risks, involves people with serious mental and physical illness, or enrolls people with other potential vulnerabilities in the research situation. Respondents expressed decreasing levels of acceptance of participation in research that posed burdens of increasing severity. Participation in protocols with possibly life-threatening consequences was perceived as least acceptable (mean = 1.82, sd = 1.29). Research on serious illnesses, including HIV, cancer, schizophrenia, depression, and post-traumatic stress disorder, was seen as ethically acceptable across respondent groups (range of means = [4.0, 4.7]). Mentally ill volunteers expressed levels of ethical acceptability for physical illness research and mental illness research as acceptable and similar, while physically ill volunteers expressed greater ethical acceptability for physical illness research than for mental illness research. Mentally ill, physically ill, and healthy participants expressed neutral to favorable perspectives regarding the ethical

While agreement is growing that mental illness burdens the North American economy, how it impacts productivity--particularly compared to physical illness--is unclear. Hypothesizing that lost work days are only the tip of the iceberg, we also examined the association of mental and chronic physical illness with partial work days and days requiring extra effort to function. Data from 4225 employed individuals, aged 18-54, were analyzed. These were a subset of respondents to the Ontario Health Survey's Mental Health Supplement, a 1990/91 epidemiologic survey of households across Ontario, Canada. Psychiatric disorder was assessed using the University of Michigan' modification of WHO's Composite International Diagnostic Interview (UM-CIDI). Similar to US reports, professional/managerial groups had lower rates of affective and anxiety disorders and fewer disability days compared to the rest of the workforce. However, no single occupational group was consistently at greater risk for either physical or psychiatric problems. Even after accounting for sociodemographic characteristics and work conditions, mental and physical status had clear, but different, impacts on productivity. Physical conditions alone had a fairly constant effect across all types of disability days and were the largest contributor to total work day loss. They also significantly impacted partial and extra effort days but were far less important than conditions involving a mental disorder. Respondents with mental health problems, either alone or in combination with physical illnesses, appeared more likely to go to work but to require greater effort to function. WHO projects that mental illness will become the second most important cause of global disease burden in the next century. Our findings suggest that among working individuals, it affects productivity more subtly than does physical illness. However, with an estimated eight percent of Ontario's workforce experiencing more than two months annually of

Mateycik, Frances Ann

This research project investigates students' development of problem solving schemata while using strategies that facilitate the process of using solved examples to assist with a new problem (case reuse). Focus group learning interviews were used to explore students' perceptions and understanding of several problem solving strategies. Individual clinical interviews were conducted and quantitative examination data were collected to assess students' conceptual understanding, knowledge organization, and problem solving performance on a variety of problem tasks. The study began with a short one-time treatment of two independent, research-based strategies chosen to facilitate case reuse. Exploration of students' perceptions and use of the strategies lead investigators to select one of the two strategies to be implemented over a full semester of focus group interviews. The strategy chosen was structure mapping. Structure maps are defined as visual representations of quantities and their associations. They were created by experts to model the appropriate mental organization of knowledge elements for a given physical concept. Students were asked to use these maps as they were comfortable while problem solving. Data obtained from this phase of our study (Phase I) offered no evidence of improved problem solving schema. The 11 contact hour study was barely sufficient time for students to become comfortable using the maps. A set of simpler strategies were selected for their more explicit facilitation of analogical reasoning, and were used together during two more semester long focus group treatments (Phase II and Phase III of this study). These strategies included the use of a step-by-step process aimed at reducing cognitive load associated with mathematical procedure, direct reflection of principles involved in a given set of problems, and the direct comparison of problem pairs designed to be void of surface similarities (similar objects or object orientations) and sharing

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.

Problem Solving in Physics: Undergraduates' Framing, Procedures, and Decision Making

Science.gov (United States)

Modir, Bahar

In this dissertation I will start with the broad research question of what does problem solving in upper division physics look like? My focus in this study is on students' problem solving in physics theory courses. Some mathematical formalisms are common across all physics core courses such as using the process of separation of variables, doing Taylor series, or using the orthogonality properties of mathematical functions to set terms equal to zero. However, there are slight differences in their use of these mathematical formalisms across different courses, possibly because of how students map different physical systems to these processes. Thus, my first main research question aims to answer how students perform these recurring processes across upper division physics courses. I break this broad question into three particular research questions: What knowledge pieces do students use to make connections between physics and procedural math? How do students use their knowledge pieces coherently to provide reasoning strategies in estimation problems? How do students look ahead into the problem to read the information out of the physical scenario to align their use of math in physics? Building on the previous body of the literature, I will use the theory family of Knowledge in Pieces and provide evidence to expand this theoretical foundation. I will compare my study with previous studies and provide suggestions on how to generalize these theory expansions for future use. My experimental data mostly come from video-based classroom data. Students in groups of 2-4 students solve in-class problems in quantum mechanics and electromagnetic fields 1 courses collaboratively. In addition, I will analyze clinical interviews to demonstrate how a single case study student plays an epistemic game to estimate the total energy in a hurricane. My second research question is more focused on a particular instructional context. How do students frame problem solving in quantum mechanics? I

Projected regression method for solving Fredholm integral equations arising in the analytic continuation problem of quantum physics

Arsenault, Louis-François; Millis, Andrew J; Neuberg, Richard; Hannah, Lauren A

2017-01-01

We present a supervised machine learning approach to the inversion of Fredholm integrals of the first kind as they arise, for example, in the analytic continuation problem of quantum many-body physics. The approach provides a natural regularization for the ill-conditioned inverse of the Fredholm kernel, as well as an efficient and stable treatment of constraints. The key observation is that the stability of the forward problem permits the construction of a large database of outputs for physically meaningful inputs. Applying machine learning to this database generates a regression function of controlled complexity, which returns approximate solutions for previously unseen inputs; the approximate solutions are then projected onto the subspace of functions satisfying relevant constraints. Under standard error metrics the method performs as well or better than the Maximum Entropy method for low input noise and is substantially more robust to increased input noise. We suggest that the methodology will be similarly effective for other problems involving a formally ill-conditioned inversion of an integral operator, provided that the forward problem can be efficiently solved.

To compare chronic physical health disorder prevalence amongst Australian adults with and without mental illness. Total n=1,716 participants (58% female) with a mean age of 52 ± 13 years (range: 18 to 89 years) completed an online survey of Australian adults in 2010. Outcome measures including prevalence of chronic physical conditions and self-reported body mass index (BMI) in n=387 (23%) with a self-reported mental illness diagnosis were compared to respondents without mental illness. A significantly higher proportion of participants with mental illness were obese (BMI ≥ 30; 31 vs 24%, p=0.005). Adjusted odds ratios (OR) for coronary heart disease, diabetes, chronic bronchitis or emphysema, asthma, irritable bowel syndrome, and food allergies or intolerances (OR range: 1.54-3.19) demonstrated that chronic physical disorders were significantly more common in participants with a mental illness. Australian adults with a diagnosis for mental illness have a significantly increased likelihood of demonstrating chronic physical health disorders compared to persons without mental illness. Health professionals must be alert to the increased likelihood of comorbid chronic physical disorders in persons with a mental illness and should consider the adoption of holistic approaches when treating those with either a mental or physical illness. © 2012 The Authors.

Illness-related absenteeism is a major threat to work productivity. Our objective was to assess the relationship between physical activity and unplanned illness-related absenteeism from work. We implemented physical activity program for sedentary non-clinician employees of a tertiary medical center. Financial rewards were available for reaching accelerometer-measured ambulatory physical activity goals over a 24-week period. We categorized participants into three groups based on mean levels of physical activity: low (0-74 min/week), medium (75-149 min/week) and meeting CDC guidelines (≥150 min/week). We built a multivariable Poisson regression model to evaluate the relationship between physical activity and rates of unplanned illness-related absenteeism. The sample consisted of 292 employees who participated in the program. Their mean age was 38 years (SD 11), 83% were female, and 38% were obese. Over the 24 intervention weeks, participants engaged in a mean of 90 min/week (SD 74) of physical activity and missed a mean of 14 hours of work (SD 38) due to illness. Unplanned absenteeism due to illness was associated with physical activity. As compared to the group meeting CDC guidelines, in multivariable analyses those in the medium physical activity group had a 2.4 (95% CI 1.3-4.5) fold higher rate of illness-related absenteeism and those in the lowest physical activity group had a 3.5 (95% CI 1.7-7.2) fold higher rate of illness-related absenteeism. Less physical activity was associated with more illness-related absenteeism. Workforce-based interventions to increase physical activity may thus be a promising vehicle to reduce unplanned illness-related absenteeism.

2017-04-01

Shortened life expectancy of people with mental illness is now widely known and the focus of research and policy activity. To date, research has primarily reflected perspectives of health professionals with limited attention to the views and opinions of those most closely affected. The voice of carers is particularly minimal, despite policy stipulating carer participation is required for mental health services. To present views and opinions of carers regarding physical health of the people they care for. Qualitative exploratory. Two focus groups and one individual interview were conducted with 13 people identifying as carers of a person with mental illness. Research was conducted in the Australian Capital Territory. Data analysis was based on the thematic framework of Braun and Clarke. Two main themes were interaction between physical and mental health; and, carers' own physical and mental health. Participants described the impact of mental illness and its treatments on physical health, including their own. Carers are acknowledged as crucial for the delivery of high quality mental health services. Therefore they have an important role to play in addressing the poor physical health of people with mental illness. Hearing their views and opinions is essential.

People diagnosed with serious mental illness have higher rates of physical morbidity and decreased longevity, yet these people are not adequately served by health care systems. Nurses may provide improved physical health support to consumers with serious mental illness but this is partly dependent on nurses having necessary skills and interest in training opportunities for this component of their work. This survey investigated Australian nurses' interest in training across areas of physical health care including lifestyle factors, cardiovascular disease, and identifying health risks. A nation-wide online survey of nurse members of the Australian College of Mental Health Nurses. The survey included an adapted version of a sub-section of the Physical Health Attitudes Scale. Participants were asked to indicate their interest in various aspects of physical health care training. Most (91.6%) participants viewed educating nurses in physical health care as of moderate or significant value in improving the physical health of people with serious mental illness. Interest in training in all areas of physical health care was over 60% across the health care settings investigated (e.g. public, private, primary care). Forty-two percent sought training in all nine areas of physical health care, from supporting people with diabetes, to assisting consumers with sexually-related and lifestyle issues. The findings suggest that nurses in mental health services in Australia acknowledge the importance of training to improve physical health care of consumers with serious mental illness. Training programs and learning opportunities for nurses are necessary to reduce inequalities in health of people with serious mental illness. Copyright © 2013. Published by Elsevier Ltd.

Impact of Context-Rich, Multifaceted Problems on Students' Attitudes Towards Problem-Solving

Science.gov (United States)

Ogilvie, Craig

2008-04-01

Young scientists and engineers need strong problem-solving skills to enable them to address the broad challenges they will face in their careers. These challenges will likely be ill-defined and open-ended with either unclear goals, insufficient constraints, multiple possible solutions, and different criteria for evaluating solutions so that our young scientists and engineers must be able to make judgments and defend their proposed solutions. In contrast, many students believe that problem-solving is being able to apply set procedures or algorithms to tasks and that their job as students is to master an ever-increasing list of procedures. This gap between students' beliefs and the broader, deeper approaches of experts is a strong barrier to the educational challenge of preparing students to succeed in their future careers. To start to address this gap, we have used multi-faceted, context-rich problems in a sophomore calculus-based physics course. To assess whether there was any change in students' attitudes or beliefs towards problem-solving, students were asked to reflect on their problem-solving at the beginning and at the end of the semester. These reflections were coded as containing one or more problem-solving ideas. The change in students' beliefs will be shown in this talk.

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

Science.gov (United States)

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

2016-12-01

There are significant inequalities in physical health and life expectancy between people with and without a mental illness. Understanding perspectives of people with mental illness on personal meanings of physical health is essential to ensuring health services are aligned with consumer understandings, needs, and values. A qualitative exploratory study was undertaken involving focus groups with 31 consumers in The Australian Capital Territory, Australia. Participants were asked: "What does physical health mean to you?" Thematic analysis was applied to interview transcripts. Five themes are discussed, representing different emphases in the meaning of physical health: (1) physical and mental are interconnected, (2) absence of disease, (3) moving the body, (4) struggling for healthy diet, and (5) functioning and participation. Physical pain was a difficulty that arose across these themes. Mental health consumers see physical health as always connected with well-being. Nurses would benefit from been informed by consumer understandings of physical health. In addition, there should be more attention to quality of life measures of people with mental illness as these are more congruent with consumer perspectives on physical health than biomedical measures.

To ascertain the views and experiences of mental health consumers regarding the availability and quality of care and treatment received for their physical health needs. People diagnosed with mental illness have higher occurrence of physical health problems. Responsive health care services are crucial for prevention and management of physical health problems, and for reducing disparities in health between people diagnosed with mental illness and those who are not. There is limited research giving voice to consumer perspectives on their experiences with health care providers. Exploratory qualitative. Focus group interviews with mental health consumers accessed via a consumer network group in a region of Australia (n = 31). All interview audio recordings were transcribed professionally. Interviews were thematically analysed. The main themes were: symptomising; failure to act and alertness to prejudice. The first two themes were consumer perceptions of the actions and behaviours of health professionals, and the third describes consumer responses to these behaviours and actions. Consumers described increased risks of illness and death because of undiagnosed physical illness despite their physical health advice-seeking as the reason for the health consultation. Health care providers' non-recognition of physical health problems presents a clear example of a significant and potentially life threatening health inequity. The service provider responses described by participants suggest that mental health consumers' physical health needs may not be taken seriously. Clinicians need to take seriously the physical health needs and concerns of people with mental illness. Nurses can play a crucial role in the prevention of diagnostic overshadowing as part of a broader direction of balancing biomedical perspectives with other approaches to health care. © 2016 John Wiley & Sons Ltd.

Intuitive physics knowledge, physics problem solving and the role of mathematical equations

Directory of Open Access Journals (Sweden)

Laura Buteler

2012-09-01

Full Text Available The present work explores the role that mathematical equations play in modifying students’ physical intuition (diSessa, 1993. The work is carried out assuming that students achieve a great deal of the refinement in their physical intuitions during problem solving (Sherin, 2006. The study is guided by the question of how the use of mathematical equations contributes to this refinement. The authors aim at expanding on Sherin´s (2006 hypothesis, suggesting a more bounding relation between physical intuitions and mathematics. In this scenario, intuitions play a more compelling role in “deciding” which equations are acceptable and which are not. Our hypothesis is constructed on the basis of three cases: the first published by Sherin (2006 and two more from registries of our own. The three cases are compared and analyzed in relation to the role of mathematical equations in refining – or not – the intuitive knowledge students bring to play during problem solving.

Psychogenic Explanations of Physical Illness: Time to Examine the Evidence.

Science.gov (United States)

Wilshire, Carolyn E; Ward, Tony

2016-09-01

In some patients with chronic physical complaints, detailed examination fails to reveal a well-recognized underlying disease process. In this situation, the physician may suspect a psychological cause. In this review, we critically evaluated the evidence for this causal claim, focusing on complaints presenting as neurological disorders. There were four main conclusions. First, patients with these complaints frequently exhibit psychopathology but not consistently more often than patients with a comparable "organic" diagnosis, so a causal role cannot be inferred. Second, these patients report a high incidence of adverse life experiences, but again, there is insufficient evidence to indicate a causal role for any particular type of experience. Third, although psychogenic illnesses are believed to be more responsive to psychological interventions than comparable "organic" illnesses, there is currently no evidence to support this claim. Finally, recent evidence suggests that biological and physical factors play a much greater causal role in these illnesses than previously believed. We conclude that there is currently little evidential support for psychogenic theories of illness in the neurological domain. In future research, researchers need to take a wider view concerning the etiology of these illnesses. © The Author(s) 2016.

To examine the association between mental illness and chronic physical conditions in older adults and investigate whether co-occurring substance use disorders (SUDs) are associated with greater risk of chronic physical conditions beyond mental illness alone. A retrospective cross-sectional study. Medicare and Medicaid programs in Massachusetts. Massachusetts Medicare and Medicaid members aged 65 and older as of January 1, 2005 (N = 679,182). Diagnoses recorded on Medicare and Medicaid claims were used to identify mental illness, SUDs, and 15 selected chronic physical conditions. Community-dwelling older adults with mental illness or SUDs had higher adjusted risk for 14 of the 15 selected chronic physical conditions than those without these disorders; the only exception was eye diseases. Moreover, those with co-occurring SUDs and mental illness had the highest adjusted risk for 11 of these chronic conditions. For residents of long-term care facilities, mental illness and SUDs were only moderately associated with the risk of chronic physical conditions. Community-dwelling older adults with mental illness or SUDs, particularly when they co-occurred, had substantially greater medical comorbidity than those without these disorders. For residents of long-term care facilities, the generally uniformly high medical comorbidity may have moderated this relationship, although their high prevalence of mental illness and SUDs signified greater healthcare needs. These findings strongly suggest the imminent need for integrating general medical care, mental health services, and addiction health services for older adults with mental illness or SUDs. © 2011, Copyright the Authors Journal compilation © 2011, The American Geriatrics Society.

Effective social problem-solving abilities can contribute to decreased risk of poor mental health. In addition, physical activity has a favorable effect on mental health. These previous studies suggest that physical activity and social problem-solving ability can interact by helping to sustain mental health. The present study aimed to determine the association between attitude and practice of physical activity and social problem-solving ability among university students. Information on physical activity and social problem-solving was collected using a self-administered questionnaire. We analyzed data from 185 students who participated in the questionnaire surveys and psychological tests. Social problem-solving as measured by the Social Problem-Solving Inventory-Revised (SPSI-R) (median score 10.85) was the dependent variable. Multiple logistic regression analysis was employed to calculate the odds ratios (ORs) and 95% confidence intervals (CIs) for higher SPSI-R according to physical activity categories. The multiple logistic regression analysis indicated that the ORs (95% CI) in reference to participants who said they never considered exercising were 2.08 (0.69-6.93), 1.62 (0.55-5.26), 2.78 (0.86-9.77), and 6.23 (1.81-23.97) for participants who did not exercise but intended to start, tried to exercise but did not, exercised but not regularly, and exercised regularly, respectively. This finding suggested that positive linear association between physical activity and social problem-solving ability (p value for linear trend social problem-solving ability.

Trauma and posttraumatic stress disorder (PTSD) frequently co-occur with serious mental illness, yet the unique mental and physical health influences of childhood physical abuse (CPA), childhood sexual abuse (CSA), and forced sexual trauma on individuals with serious mental illness remain unevaluated. The present study of 172 individuals with serious mental illness investigated the adverse effects of CPA, CSA, and forced sexual trauma on severity of PTSD and depression, and overall mental and physical health functioning. Data analysis consisted of chi-square tests, independent t tests, bivariate odds ratios, and linear regressions. Prevalence of CPA (44.8%), CSA (29.1%), and forced sexual trauma (33.1%) were elevated, and nearly one third of participants (31.4%) reported clinical PTSD. Participants exposed to CSA or forced sexual trauma evidenced bivariate ORs ranging from 4.13 to 7.02 for PTSD, 2.44 to 2.50 for major depression, and 2.14 to 2.31 for serious physical illness/disability. Sexual trauma exposure associated with heightened PTSD and depression, and reduced mental and physical health functioning, with CSA uniquely predicting PTSD, depression, and physical health difficulties. CPA less significantly affected these clinical domains. Sexual traumas have profound negative effects on mental and physical health outcomes among individuals with serious mental illness; increased screening and treatment of sexual traumas is needed.

Science.gov (United States)

Mercan, Fatih C.

This study examines epistemological beliefs of physics undergraduate and graduate students and faculty in the context of solving a well-structured and an ill-structured problem. The data collection consisted of a think aloud problem solving session followed by a semi-structured interview conducted with 50 participants, 10 participants at freshmen, seniors, masters, PhD, and faculty levels. The data analysis involved (a) identification of the range of beliefs about knowledge in the context of the well-structured and the ill-structured problem solving, (b) construction of a framework that unites the individual beliefs identified in each problem context under the same conceptual base, and (c) comparisons of the problem contexts and expertise level groups using the framework. The results of the comparison of the contexts of the well-structured and the ill-structured problem showed that (a) authoritative beliefs about knowledge were expressed in the well-structured problem context, (b) relativistic and religious beliefs about knowledge were expressed in the ill-structured problem context, and (c) rational, empirical, modeling beliefs about knowledge were expressed in both problem contexts. The results of the comparison of the expertise level groups showed that (a) undergraduates expressed authoritative beliefs about knowledge more than graduate students and faculty did not express authoritative beliefs, (b) faculty expressed modeling beliefs about knowledge more than graduate students and undergraduates did not express modeling beliefs, and (c) there were no differences in rational, empirical, experiential, relativistic, and religious beliefs about knowledge among the expertise level groups. As the expertise level increased the number of participants who expressed authoritative beliefs about knowledge decreased and the number of participants who expressed modeling based beliefs about knowledge increased. The results of this study implied that existing developmental and

In this paper we present the results of a study on the effectiveness of combinations of delivery modes of distance education in learning problem-solving skills in a distance education introductory physics course. A problem-solving instruction with the explicit teaching of a problem-solving strategy and worked-out examples were implemented in the course. The study used the ex post facto research design with stratified sampling to investigate the effect of the learning of a problem-solving strategy on the problem-solving performance. The number of problems attempted and the mean frequency of using a strategy in solving problems in the three course presentation modes were compared. The finding of the study indicated that combining the different course presentation modes had no statistically significant effect in the learning of problem-solving skills in the distance education course.

As all-optical networks grow with ever increasing ultra-high speed, the communication quality suffers seriously from physical layer impairments ( PLIs) .The same problem still exists in software defined optical network ( SDON) controlled by OpenFlow.Aimed to solve this problem, a PLIs tol-erance based lightpath provision scheme is proposed for OpenFlow controlled optical networks.This proposed approach not only takes the OSNR model to represent those linear PLIs factors, but also in-troduces those nonlinear factors into the OSNR model.Thus, the proposed scheme is able to cover most PLIs factors of each optical link and conduct optical lightpath provison with better communica-tion quality.Moreover, PLIs tolerance model is also set up and considered in this work with some necessary extension to OpenFlow protocols to achieve better compatibility between physical layer im-pairments factors and various services connections.Simulation results show that the proposed scheme is able to get better performance in terms of packet loss rate and connection setup time.

Full Text Available Students’ attitudes and approaches to physics problem solving can impact how well they learn physics and how successful they are in solving physics problems. Prior research in the U.S. using a validated Attitude and Approaches to Problem Solving (AAPS survey suggests that there are major differences between students in introductory physics and astronomy courses and physics experts in terms of their attitudes and approaches to physics problem solving. Here we discuss the validation, administration, and analysis of data for the Turkish version of the AAPS survey for high school and university students in Turkey. After the validation and administration of the Turkish version of the survey, the analysis of the data was conducted by grouping the data by grade level, school type, and gender. While there are no statistically significant differences between the averages of various groups on the survey, overall, the university students in Turkey were more expertlike than vocational high school students. On an item by item basis, there are statistically differences between the averages of the groups on many items. For example, on average, the university students demonstrated less expertlike attitudes about the role of equations and formulas in problem solving, in solving difficult problems, and in knowing when the solution is not correct, whereas they displayed more expertlike attitudes and approaches on items related to metacognition in physics problem solving. A principal component analysis on the data yields item clusters into which the student responses on various survey items can be grouped. A comparison of the responses of the Turkish and American university students enrolled in algebra-based introductory physics courses shows that on more than half of the items, the responses of these two groups were statistically significantly different, with the U.S. students on average responding to the items in a more expertlike manner.

PURPOSE Cognitive impairment after critical illness is common and debilitating. We developed a cognitive therapy program for critically ill patients and assessed the feasibility and safety of administering combined cognitive and physical therapy early during a critical illness. METHODS We randomized 87 medical and surgical ICU patients with respiratory failure and/or shock in a 1:1:2 manner to three groups: usual care, early once-daily physical therapy, or early once-daily physical therapy plus a novel, progressive, twice-daily cognitive therapy protocol. Cognitive therapy included orientation, memory, attention, and problem solving exercises, and other activities. We assessed feasibility outcomes of the early cognitive plus physical therapy intervention. At 3-months, we also assessed cognitive, functional and health-related quality of life outcomes. Data are presented as median [interquartile range] or frequency (%). RESULTS Early cognitive therapy was a delivered to 41/43 (95%) of cognitive plus physical therapy patients on 100% [92–100%] of study days beginning 1.0 [1.0–1.0] day following enrollment. Physical therapy was received by 17/22 (77%) of usual care patients, by 21/22 (95%) of physical therapy only patients and 42/43 (98%) of cognitive plus physical therapy patients on 17% [10–26%], 67% [46–87%] and 75% [59–88%] of study days, respectively. Cognitive, functional and health-related quality of life outcomes did not differ between groups at 3-month follow-up. CONCLUSIONS This pilot study demonstrates that early rehabilitation can be extended beyond physical therapy to include cognitive therapy. Future work to determine optimal patient selection, intensity of treatment and benefits of cognitive therapy in the critically ill is needed. PMID:24257969

To identify nurse perceptions on the potential value of general and specific nursing approaches to improving physical health outcomes of people with serious mental illness. People diagnosed with serious mental illnesses experience heightened rates of physical illnesses and can be supported better via healthcare system prevention and management. Nurses working in mental health are a critical part of a system-wide approach to improving physical health care, but there is little known on their views on specific approaches within Australia (e.g. screening for risks, stigma reduction). A national, cross-sectional and nonrandom survey study delivered online. Members of the Australian College of Mental Health Nurses (n = 643), representing nurses employed in mental healthcare services across Australia (71·6% from public mental health services). Participants were asked to rate the potential of nine nurse-based strategies for improving physical health (options: 'yes', 'no', 'not sure') and the potential value of 10 nursing and general strategies for improving physical health (rating from 'negative value' to 'significant value'). There was a high endorsement of all nine nurse-based strategies for physical health (e.g. lifestyle programmes, screening, linking services), although there was less support for reducing antipsychotics or advocating for fewer side effects. Participants mainly viewed all strategies as of moderate to significant value, with the most promising value attached to colocation of primary and mental care services, lifestyle programmes and improving primary care services (reduce stigma, train GPs). Australian nurses working in mental health services view a range of nurse-based strategies for improving physical healthcare services and standards as important. Nurses collectively need to work with consumers, health agencies and the general public to further define how to organise and implement physical health integration strategies, towards more comprehensive

2018-04-01

This research aimed to describe behaviors of mathematics and physics students in solving problem of the vector concept in physics context. The subjects of the research were students who enrolled in Mathematics Education Study Program and Physics Education Study Program of FKIP Universitas Tadulako. The selected participants were students who received the highest score in vector fundamental concept test in each study program. The data were collected through thinking-aloud activity followed by an interview. The steps of data analysis included data reduction, display, and conclusion drawing. The credibility of the data was tested using a triangulation method. Based on the data analysis, it can be concluded that the two groups of students did not show fundamental differences in problem-solving behavior, especially in the steps of understanding the problem (identifying, collecting and analyzing facts and information), planning (looking for alternative strategies) and conducting the alternative strategy. The two groups were differ only in the evaluation aspect. In contrast to Physics students who evaluated their answer, mathematics students did not conducted an evaluation activity on their work. However, the difference was not caused by the differences in background knowledge.

There is an increased prevalence of physical illness and poor lifestyle in patients with chronic schizophrenia. It is unclear whether these are present at the onset of psychosis or develop over the course of illness. We aimed to establish whether patients experiencing their first episode of psychosis have worse physical health and lifestyle than community controls without psychosis. Eighty-nine patients with new onset illness were compared to age and sex matched controls for self-reported physical illness and cardiovascular and respiratory risk factors. Patients reported more physical health complaints, mainly respiratory, compared with age and gender matched controls (odds ratio 2.85, 95% confidence interval 1.2-6.7). Patients were more likely to be cigarette smokers (1.82, 95% CI 1.0-3.3) and eat a fast food diet (1.04, 95% CI 1.0-1.1), but these differences were accounted for by patients' unemployment status. Some risk factors for physical health problems are present at the onset of psychosis, but these may be explained by unemployment.

Use of model analysis to analyse Thai students’ attitudes and approaches to physics problem solving

Rakkapao, S.; Prasitpong, S.

2018-03-01

This study applies the model analysis technique to explore the distribution of Thai students’ attitudes and approaches to physics problem solving and how those attitudes and approaches change as a result of different experiences in physics learning. We administered the Attitudes and Approaches to Problem Solving (AAPS) survey to over 700 Thai university students from five different levels, namely students entering science, first-year science students, and second-, third- and fourth-year physics students. We found that their inferred mental states were generally mixed. The largest gap between physics experts and all levels of the students was about the role of equations and formulas in physics problem solving, and in views towards difficult problems. Most participants of all levels believed that being able to handle the mathematics is the most important part of physics problem solving. Most students’ views did not change even though they gained experiences in physics learning.

Towards a conceptual framework for identifying student difficulties with solving Real-World Problems in Physics

There is currently much focus on provision of general physical health advice to people with serious mental illness and there has been increasing pressure for services to take responsibility for providing this. To review the effects of general physical healthcare advice for people with serious mental illness. We searched the Cochrane Schizophrenia Group's Trials Register (last update search October 2012) which is based on regular searches of CINAHL, BIOSIS, AMED, EMBASE, PubMed, MEDLINE, PsycINFO and registries of Clinical Trials. There is no language, date, document type, or publication status limitations for inclusion of records in the register. All randomised clinical trials focusing on general physical health advice for people with serious mental illness.. We extracted data independently. For binary outcomes, we calculated risk ratio (RR) and its 95% confidence interval (CI), on an intention-to-treat basis. For continuous data, we estimated the mean difference (MD) between groups and its 95% CI. We employed a fixed-effect model for analyses. We assessed risk of bias for included studies and created 'Summary of findings' tables using GRADE. Seven studies are now included in this review. For the comparison of physical healthcare advice versus standard care we identified six studies (total n = 964) of limited quality. For measures of quality of life one trial found no difference (n = 54, 1 RCT, MD Lehman scale 0.20, CI -0.47 to 0.87, very low quality of evidence) but another two did for the Quality of Life Medical Outcomes Scale - mental component (n = 487, 2 RCTs, MD 3.70, CI 1.76 to 5.64). There was no difference between groups for the outcome of death (n = 487, 2 RCTs, RR 0.98, CI 0.27 to 3.56, low quality of evidence). For service use two studies presented favourable results for health advice, uptake of ill-health prevention services was significantly greater in the advice group (n = 363, 1 RCT, MD 36.90, CI 33.07 to 40.73) and service use: one or more primary

Dissociative conceptual and quantitative problem solving outcomes across interactive engagement and traditional format introductory physics

Directory of Open Access Journals (Sweden)

Mark A. McDaniel

2016-11-01

Full Text Available 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.

Current guidance suggests that we should monitor the physical health of people with serious mental illness, and there has been a significant financial investment over recent years to provide this. To assess the effectiveness of physical health monitoring, compared with standard care for people with serious mental illness. We searched the Cochrane Schizophrenia Group Trials Register (October 2009, update in October 2012), which is based on regular searches of CINAHL, EMBASE, MEDLINE and PsycINFO. All randomised clinical trials focusing on physical health monitoring versus standard care, or comparing i) self monitoring versus monitoring by a healthcare professional; ii) simple versus complex monitoring; iii) specific versus non-specific checks; iv) once only versus regular checks; or v) different guidance materials. Initially, review authors (GT, AC, SM) independently screened the search results and identified three studies as possibly fulfilling the review's criteria. On examination, however, all three were subsequently excluded. Forty-two additional citations were identified in October 2012 and screened by two review authors (JX and MW), 11 of which underwent full screening. No relevant randomised trials which assess the effectiveness of physical health monitoring in people with serious mental illness have been completed. We identified one ongoing study. There is still no evidence from randomised trials to support or refute current guidance and practice. Guidance and practice are based on expert consensus, clinical experience and good intentions rather than high quality evidence.

Lee, Sungkyu; Wong, Yin-Ling Irene; Rothbard, Aileen

2014-12-01

This study examined the effects of social network characteristics on physical health among people with serious mental illness using social transactions that are reciprocal, and the combination of objective and subjective health measures. The sample consisted of a probability sample of 231 adults with serious mental illness who resided in permanent supportive housing in Philadelphia, Pennsylvania. Path analyses were conducted to examine the relationships between social network characteristics and two aspects of medical comorbidity, objective health and subjective health. Bivariate statistics showed that individuals with medical comorbidity were more likely to have contact with their network members and had a higher level of reciprocal positive tangible support when compared to those who did not have medical comorbidity. The results of the path analyses revealed that none of the social network characteristics were associated with better physical health. The lack of a significant relationship between social networks and better physical health is contrary to prior research findings. However, this is the first study to include both types of social transactions simultaneously as predictors of better physical health for individuals with serious mental illness. A longitudinal study would provide more insight into the temporal relationship of social networks and physical health conditions of people with serious mental illness. Furthermore, the transactional nature of social relationships, particularly for those with mental health issues, requires greater exploration.

Integrating video and animation with physics problem- solving exercises on the World Wide Web

Science.gov (United States)

Titus, Aaron Patrick

1998-10-01

Problem solving is of paramount importance in teaching and learning physics. An important step in solving a problem is visualization. To help students visualize a problem, we included video clips with homework questions delivered via the World Wide Web. Although including video with physics problems has a positive effect with some problems, we found that this may not be the best way to integrate multimedia with physics problems since improving visualization is probably not as helpful as changing students' approach. To challenge how students solve problems and to help them develop a more expert-like approach, we developed a type of physics exercise called a multimedia-focused problem where students take data from an animation in order to solve a problem. Because numbers suggestive of a solution are not given in the text of the question, students have to consider the problem conceptually before analyzing it mathematically. As a result, we found that students had difficulty solving such problems compared to traditional textbook-like problems. Students' survey responses showed that students indeed had difficulty determining what was needed to solve a problem when it was not explicitly given to them in the text of the question. Analyzing think-aloud interviews where students verbalized their thoughts while solving problems, we found that multimedia-focused problems indeed required solid conceptual understanding in order for them to be solved correctly. As a result, we believe that when integrated with instruction, multimedia-focused problems can be a valuable tool in helping students develop better conceptual understanding and more expert-like problem solving skills by challenging novice beliefs and problem solving approaches. Multimedia-focused problems may also be useful for diagnosing conceptual understanding and problem skills.

Psychological interventions for mental health disorders in children with chronic physical illness: a systematic review.

2015-04-01

Children with chronic physical illness are significantly more likely to develop common psychiatric symptoms than otherwise healthy children. These children therefore warrant effective integrated healthcare yet it is not established whether the known, effective, psychological treatments for symptoms of common childhood mental health disorders work in children with chronic physical illness. EMBASE, MEDLINE, PsycINFO and CINAHL databases were searched with predefined terms relating to evidence-based psychological interventions for psychiatric symptoms in children with chronic physical illness. We included all studies (randomised and non-randomised designs) investigating interventions aimed primarily at treating common psychiatric symptoms in children with a chronic physical illness in the review. Two reviewers independently assessed the relevance of abstracts identified, extracted data and undertook quality analysis. Ten studies (209 children, including 70 in control groups) met the criteria for inclusion in the review. All studies demonstrated some positive outcomes of cognitive behavioural therapy for the treatment of psychiatric symptoms in children with chronic physical illness. Only two randomised controlled trials, both investigating interventions for symptoms of depression, were found. There is preliminary evidence that cognitive behavioural therapy has positive effects in the treatment of symptoms of depression and anxiety in children with chronic physical illness. However, the current evidence base is weak and fully powered randomised controlled trials are needed to establish the efficacy of psychological treatments in this vulnerable population.

Although schizophrenia alters the sense of personal identity, little is known about the impact of illness-related autobiographical events on patients' self-representation. We investigated self-defining memories (SDM) in 24 patients with schizophrenia and 24 controls to explore how illness-related SDM were integrated into the self at both the cognitive (how participants are able to give a meaning to past events: meaning making) and affective levels (how participants can re-experience past negative events as less negative: redemption and benefaction effects). We found that 26% of freely recalled SDM referred to their illness in patients. Further, while meaning making was impaired in patients for both illness-related and other SDM, illness-related SDM were characterized by a higher redemption and benefaction effects than other SDM. Our results highlight that despite a reduced ability to give a meaning to illness-related episodes, emotional processing seems to allow these events to become positively integrated into patients' life stories. This study provides new findings about the construction of the self in relation to psychotic episodes in patients with schizophrenia. We discuss clinical implications of our results that are helpful to guide cognitive interventions. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

2012-06-01

Physical health in people with mental illness is often compromised. Chronic physical conditions and disease risk factors occur at higher rates than in the general population. Although substantial research exists regarding mental-physical comorbidities in middle to older-aged adults and mental illness consequential to childhood physical illness, research addressing physical health in young people/emerging adults of 16-24 years with primary mental illnesses is minimal. Health problems often track from youth to adulthood, indicating a need to better recognize and understand the overall health of young people with mental illness. This paper reports findings from an integrative review of published research investigating physical health of emerging/young adults with mental illness. A total of 18 research papers were systematically analysed. The review found that comorbid mental-physical illness/conditions were evident across a wide age span. Specific physical health problems, including pain, gastrointestinal, and respiratory disorders, were apparent in those 16 years to those in their mid-late 20s, and/or with first episode psychosis. Lifestyle risk factors for cardiometabolic disorders occurred with some frequency and originated prior to adulthood. These findings highlight the need for targeted health screening and illness prevention strategies for emerging/young adults with mental health problems and draws attention to the need for young people to be supported in their health-care behaviours. © 2012 The Authors.

The aim of the present study was to evaluate the association between illness perceptions and the ability to cope with physical and mental health problems in a large cohort of systemic sclerosis (SSc) patients. This was a cross-sectional study in 217 systemic sclerosis patients from the Belgian Systemic Sclerosis Cohort. Illness perception and coping were measured by the Revised Illness Perception Questionnaire and a coping questionnaire--the Coping Orientation of Problem Experience inventory (COPE). Physical and mental health-related quality of life was measured by the 36-item short-form health survey (SF-36), as were disease activity and several severity parameters. The relationship between illness perceptions and the ability to cope with physical/mental health problems was examined using multiple linear regression analysis. According to LeRoy's classification, 49 patients had limited SSc (lSSc), 129 had limited cutaneous SSc (lcSSc) and 39 had diffuse cutaneous SSc (dcSSc). Median disease duration was five years and the modified Rodnan skin score was 4. Good physical health was significantly associated with the lcSSc subtype and low disease activity (p consequences' and strong 'illness identity' correlated with poor physical health (p mental health was associated with low illness identity scores and low 'emotional response' scores (p mental health compared with the illness perception items.

Knowledge about the beneficial role of physical activity (PA) for health and school performance is growing. Studies investigating the link between PA and school absenteeism due to illness are lacking. Therefore we investigated associations between habitual PA and school absenteeism due to illness in adolescents and explored whether mental health and cardiovascular fitness mediated this association. 328 Students in grades 7 and 9 (mean age 13.8 years; 49% boys) were included. PA was measured o...

Quality of life of people with severe mental illness may be decrease by the high occurrence of metabolic and cardiovascular diseases. Physical fitness emerges as a modifying factor in this population through physical activity and this modification could influence in the quality of life of this population. The aim of the present study is to determine the contribution of physical fitness to the quality of life of people with severe mental illness. In the current study, a physiotherapist and an occupational therapist assessed 62 people with severe mental illness. Physical fitness was measured with a range of 11 fitness tests that covered flexibility, strength, balance, and endurance. To assess quality of life the EQ-5D-3 L scale was used, which measures five dimensions (mobility, self-care, usual activities, pain-discomfort, and anxiety-depression). Significant correlations are presented between the quality of life and primary variables of physical fitness (balance, endurance, and upper limb strength). Endurance explained 22.9% of the variance of the quality of life in people with severe mental illness. Functional reach added another 36.2% variance to the prediction of quality of life. The results of the present study suggest that some variables of physical fitness are associated with quality of life in people with severe mental illness. The improvement in physical fitness of this population should be a primary objective. ClinicalTrials.gov Identifier: NCT02413164 "retrospective registered" Registered Febr 2017.

In western countries, negative illness perceptions are associated with poor health status and affect health outcomes in primary care populations. The aim of this study is to examine the relationship between illness perception and mental and physical health status in general hospital outpatients in China. This multicentre, cross-sectional study analysed a total of 281 consecutive patients from four general hospital outpatient departments of internal medicine and traditional Chinese medicine in Beijing and Kunming. The patients answered questionnaires concerning illness perception (Brief-IPQ), somatic symptom severity (Patient Health Questionnaire-15), illness behaviour (Scale for the Assessment of Illness Behaviour), emotional distress (Hospital Anxiety and Depression Scale) and health-related quality of life (Twelve-Item Short Form Health Survey). Negative illness perception, especially negative emotional reactions, perceived illness consequences, encumbering illness concerns, and strong illness identity were significantly associated with high emotional distress, impairing illness consequences, and a low mental and physical quality of life. Using a multiple linear regression model, five strongest correlates of negative illness perception were high anxiety, seeking diagnosis verification, low mental and physical quality of life and high somatic symptom severity. The variance explained by this model was 35%. Chinese general hospital outpatients showed associations between negative illness perceptions and poor mental and physical health status that were similar to those of primary care patients in western countries. The main difference was that no association with perceived illness control was found in Chinese patients. Chinese physicians should be sensitised to their patients' negative illness perceptions and should focus on helping patients cope with uncertainty and anxiety by providing an understandable illness model and increasing control beliefs.

Aggression is one of the chief determinants of caregiver burden in severe mental illnesses. Clinical and treatment implications of aggression in mental illness are predominantly studied in perspectives of mental health care professionals. Coping style of caregivers towards aggression of persons with mental illness is understudied. So we studied coping strategies used by caregivers of patients with severe mental illness towards aggressive behaviors of patients and relationship between aggressive behavior and coping strategies. We assessed two hundreds and seventy caregivers of patients with severe mental illness attending outpatient psychiatry department using Modified Overt Aggression Scale and the Ways of Coping Scale - revised. 95.6% of the caregivers perceived verbal aggression followed by aggression against property (67%), auto aggression (33.7%) and physical aggression (25.6%). The study revealed that adaptive coping strategies - planful problem solving and seeking social support were used by 40% each of caregivers to deal with aggressive behavior. Only 4.4% of caregivers resorted to escape avoidance which is maladaptive coping strategy. Though adaptive strategies were used by caregivers these were not used in appropriate situations. Physical aggression and aggression against property were not significantly associated with planful problem solving (r = 0.105; p = 0.08 and r = 0.110; p = 0.07 respectively). But verbal aggression, aggression against property and physical aggression were associated with escape avoidance (r = 0.152; p = 0.01 and r = 0.168; p = 0.01 and r = 0.23; p = mental illness is maladaptive with respect to aggression. Coping skills training would play a major role to address this issue. Copyright © 2018 Elsevier B.V. All rights reserved.

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.

The aim of this study was to identify treatment-specific predictors of the effectiveness of a method of evidence-based treatment: cognitive treatment of illness perceptions. This study focuses on what treatment works for whom, whereas most prognostic studies focusing on chronic non-specific low back pain rehabilitation aim to reduce the heterogeneity of the population of patients who are suitable for rehabilitation treatment in general. Three treatment-specific predictors were studied in patients with chronic non-specific low back pain receiving cognitive treatment of illness perceptions: a rational approach to problem-solving, discussion skills and verbal skills. Hierarchical linear regression analysis was used to assess their predictive value. Short-term changes in physical activity, measured with the Patient-Specific Functioning List, were the outcome measure for cognitive treatment of illness perceptions effect. A total of 156 patients with chronic non-specific low back pain participated in the study. Rational problem-solving was found to be a significant predictor for the change in physical activity. Discussion skills and verbal skills were non-significant. Rational problem-solving explained 3.9% of the total variance. The rational problem-solving scale results are encouraging, because chronic non-specific low back pain problems are complex by nature and can be influenced by a variety of factors. A minimum score of 44 points on the rational problem-solving scale may assist clinicians in selecting the most appropriate candidates for cognitive treatment of illness perceptions.

Do New Caledonian crows solve physical problems through causal reasoning?

Taylor, A.H.; Hunt, G.R.; Medina, F.S.; Gray, R.D.

2008-01-01

The extent to which animals other than humans can reason about physical problems is contentious. The benchmark test for this ability has been the trap-tube task. We presented New Caledonian crows with a series of two-trap versions of this problem. Three out of six crows solved the initial trap-tube. These crows continued to avoid the trap when the arbitrary features that had previously been associated with successful performances were removed. However, they did not avoid the trap when a hole and a functional trap were in the tube. In contrast to a recent primate study, the three crows then solved a causally equivalent but visually distinct problem—the trap-table task. The performance of the three crows across the four transfers made explanations based on chance, associative learning, visual and tactile generalization, and previous dispositions unlikely. Our findings suggest that New Caledonian crows can solve complex physical problems by reasoning both causally and analogically about causal relations. Causal and analogical reasoning may form the basis of the New Caledonian crow's exceptional tool skills. PMID:18796393

Levin, Kfir; Bradley, Graham L; Duffy, Amanda

2018-01-01

This study examined whether attitudes toward euthanasia vary with type of illness and with the source of the desire to end the patient's life. The study used a 3 (illness type: cancer, schizophrenia, depression) × 2 (euthanasia type: patient-initiated, family-initiated) between-groups experimental design. An online questionnaire was administered to 324 employees and students from a Australian public university following random assignment of participants to one of the six vignette-based conditions. Attitudes toward euthanasia were more positive for patients with a physical illness than a mental illness. For a patient with cancer or depression, but not schizophrenia, approval was greater for patient-, than, family-, initiated euthanasia. Relationships between illness type and attitudes were mediated by perceptions of patient autonomy and illness controllability. Findings have implications for debate, practices, and legislation regarding euthanasia.

Participating in physical activities could be essential for reducing the multiple risk factors for health problems that persons with severe mental illness (SMI) may suffer. However, people with SMI are significantly less active than the general population. To develop knowledge about factors related to the perceived barriers hindering this population's participation in physical activities and the benefits this participation would have, a study was conducted in Israel with 86 people with mental illness living in community mental health facilities prior to their participation in a health promotion program. A mixed method was implemented and included: a scale designed to measure participants' perceptions of the barriers to and benefits of involvement in physical activities; instruments focusing on bio-psycho-social factors that may affect the level of barriers experienced; and personal interviews. The findings revealed high ranking for accessibility barriers hindering the participation in physical activities. Bio-psycho-social factors stemming from the participants' mental health, such as level of depression, were correlated with higher ranking of accessibility barriers. Bio-psycho-social factors reflecting positive mental health and health, such as positive appraisal of body weight, were correlated with lower ranking of accessibility barriers. Other barriers may include organizational and broader systemic barriers in the mental health facilities where the participants reside. These findings illuminate the need to consider the unique challenges that persons with mental illness may face in any attempt to advance their involvement in physical activity. © The Author 2014.

To compare levels of victimization and perpetration associated with bullying among children and adolescents with and without chronic physical illnesses and/or physical or sensory disabilities. In total, 107 studies were identified using a systematic search in electronic databases and cross-referencing. A random-effects meta-analysis was computed. Children and adolescents with chronic physical illness or disability were more likely to be victims of bullying in general (odds ratio [OR] = 1.65), particularly physical bullying (OR = 1.47), relational bullying (OR = 1.47), verbal bullying (OR = 1.67), cyberbullying (OR = 1.39), and illness-specific teasing (OR = 5.29). They were also more likely to be bullies in general (OR = 1.28), as well physical (OR = 1.38) and relational bullies (OR = 1.13). The effect sizes varied across different illnesses and disabilities and, in part, by visibility of the disease, school type, and year of assessment. Although most between-group differences tend to be small, some form of intervention is needed to reduce bullying among children and adolescents with chronic physical illnesses and/or physical or sensory disabilities, and illness-specific weight- and appearance-related teasing in particular. © The Author 2016.

The present study examines the concept of illness identity, the degree to which a chronic illness is integrated into one's identity, in adults with a chronic illness by validating a new self-report questionnaire, the Illness Identity Questionnaire (IIQ). Self-report questionnaires on illness identity, psychological, and physical functioning were assessed in two samples: adults with congenital heart disease (22-78 year old; n = 276) and with multisystem connective tissue disorders (systemic lupus erythematosus or systemic sclerosis; 17-81 year old; n = 241). The IIQ could differentiate four illness identity states (i.e., engulfment, rejection, acceptance, and enrichment) in both samples, based on exploratory and confirmatory factor analysis. All four subscales proved to be reliable. Rejection and engulfment were related to maladaptive psychological and physical functioning, whereas acceptance and enrichment were related to adaptive psychological and physical functioning. The present findings underscore the importance of the concept of illness identity. The IIQ, a self-report questionnaire, is introduced to measure four different illness identity states in adults with a chronic illness.

Those with mental illness are at increased risk of physical health problems. The current study aimed to examine the information available online to the Australian public about the increased risk and consequences of physical illness in those with mental health problems and the services available to address these co-morbidities. A structured online search was conducted with the search engine Google Australia (www.google.com.au) using generic search terms 'mental health information Australia', 'mental illness information Australia', 'depression', 'anxiety', and 'psychosis'. The direct content of websites was examined for information on the physical co-morbidities of mental illness. All external links on high-profile websites [the first five websites retrieved under each search term (n = 25)] were examined for information pertaining to physical health. Only 4.2% of websites informing the public about mental health contained direct content information about the increased risk of physical co-morbidities. The Australian Government's Department of Health and Ageing site did not contain any information. Of the high-profile websites, 62% had external links to resources about physical health and 55% had recommendations or resources for physical health. Most recommendations were generic. Relative to the seriousness of this problem, there is a paucity of information available to the public about the increased physical health risks associated with mental illness. Improved public awareness is the starting point of addressing this health inequity.

Objectives: To conduct a systematic review of studies that examined associations between physical illness/functional disability and suicidal behaviour (including ideation, nonfatal and fatal suicidal behaviour) among individuals aged 65 and older. Method: Articles published through November 2014 were identified through electronic searches using the ERIC, Google Scholar, PsycINFO, PubMed, and Scopus databases. Search terms used were suicid* or death wishes or deliberate self-harm. Studies about suicidal behaviour in individuals aged 65 and older with physical illness/functional disabilities were included in the review. Results: Sixty-five articles (across 61 independent samples) met inclusion criteria. Results from 59 quantitative studies conducted in four continents suggest that suicidal behaviour is associated with functional disability and numerous specific conditions including malignant diseases, neurological disorders, pain, COPD, liver disease, male genital disorders, and arthritis/arthrosis. Six qualitative studies from three continents contextualized these findings, providing insights into the subjective experiences of suicidal individuals. Implications for interventions and future research are discussed. Conclusion: Functional disability, as well as a number of specific physical illnesses, was shown to be associated with suicidal behaviour in older adults. We need to learn more about what at-risk, physically ill patients want, and need, to inform prevention efforts for older adults. PMID:26381843

2016-03-01

People with serious mental illness face significant inequalities in physical health care. As a result, the risk of cardiometabolic disorders and premature mortality is far greater than that observed in the general population. Contributiung to this disparity, is the lack of routine physical health screening by mental health clinicians. One possible solution is the implimentation of a physical health nurse consultant, whose role is to monitor and coordinate the physical health care of people with serious mental illness. Current evidence supports the implimentation of such a role, and a failure to address the widening gaps in physical health care will only serve to increase the disparities faced by people with serious mental illness. © The Author(s) 2015.

Luo, Wei; Tran, Truyen; Berk, Michael; Venkatesh, Svetha

2016-01-01

Background Although physical illnesses, routinely documented in electronic medical records (EMR), have been found to be a contributing factor to suicides, no automated systems use this information to predict suicide risk. Objective The aim of this study is to quantify the impact of physical illnesses on suicide risk, and develop a predictive model that captures this relationship using EMR data. Methods We used history of physical illnesses (except chapter V: Mental and behavioral disorders) from EMR data over different time-periods to build a lookup table that contains the probability of suicide risk for each chapter of the International Statistical Classification of Diseases and Related Health Problems, 10th Revision (ICD-10) codes. The lookup table was then used to predict the probability of suicide risk for any new assessment. Based on the different lengths of history of physical illnesses, we developed six different models to predict suicide risk. We tested the performance of developed models to predict 90-day risk using historical data over differing time-periods ranging from 3 to 48 months. A total of 16,858 assessments from 7399 mental health patients with at least one risk assessment was used for the validation of the developed model. The performance was measured using area under the receiver operating characteristic curve (AUC). Results The best predictive results were derived (AUC=0.71) using combined data across all time-periods, which significantly outperformed the clinical baseline derived from routine risk assessment (AUC=0.56). The proposed approach thus shows potential to be incorporated in the broader risk assessment processes used by clinicians. Conclusions This study provides a novel approach to exploit the history of physical illnesses extracted from EMR (ICD-10 codes without chapter V-mental and behavioral disorders) to predict suicide risk, and this model outperforms existing clinical assessments of suicide risk.

There is a growing interest in understanding the connection between mental illness (MI) and the onset of new physical illnesses among previously physically healthy individuals. Yet the role of gender is often forgotten in research focused on comorbidity of health problems. The objective of this study was to examine gender differences in the onset of physical illness in a cohort of respondents who met criteria for MI compared with a control cohort without mental health problems. This cohort study, conducted in Ontario, Canada, used a unique linked dataset with information from the 2000-2001 Canadian Community Health Survey and medical records (n=15,902). We used adjusted Cox proportional survival analysis to examine risk of onset of four physical health problems (chronic obstructive pulmonary disorder, asthma, hypertension and diabetes) for those with and without baseline MI across a 10-year period (2002-2011) among respondents aged 18-74 years. We controlled for socioeconomic and health indicators associated with health. The incidence of physical illness in the MI cohort was 28.5% among women and 29.9% among men (p=0.85) relative to controls (23.8% and 24%, respectively; p=0.48). Women in the MI cohort developed secondary physical health problems a year earlier than their male counterparts (p=0.002). Findings from the Cox proportional survival regression showed that women were at 14% reduced risk of developing physical illness, meaning that men were more disadvantaged (HR=0.89, CI 0.80 to 0.98). Those in the MI cohort were at 10 times greater risk of developing a secondary physical illness over the 10-year period (HR=1.10, CI 0.98 to 1.21). There was no significant interaction between gender and MI cohort (HR=1.05, CI 0.85 to 1.27). Policy and clinical practice have to be sensitive to these complex-needs patients. Gender-specific treatment and prevention practices can be developed to target those at higher risk of multiple health conditions.

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).

If students are to successfully grapple with authentic, complex biological problems as scientists and citizens, they need practice solving such problems during their undergraduate years. Physics education researchers have investigated student problem solving for the past three decades. Although physics and biology problems differ in structure and content, the instructional purposes align closely: explaining patterns and processes in the natural world and making predictions about physical and biological systems. In this paper, we discuss how research-supported approaches developed by physics education researchers can be adopted by biologists to enhance student problem-solving skills. First, we compare the problems that biology students are typically asked to solve with authentic, complex problems. We then describe the development of research-validated physics curricula emphasizing process skills in problem solving. We show that solving authentic, complex biology problems requires many of the same skills that practicing physicists and biologists use in representing problems, seeking relationships, making predictions, and verifying or checking solutions. We assert that acquiring these skills can help biology students become competent problem solvers. Finally, we propose how biology scholars can apply lessons from physics education in their classrooms and inspire new studies in biology education research. PMID:23737623

Individuals with serious mental illness have elevated rates of comorbid chronic general medical conditions and may benefit from interventions designed to support illness self-management. This study examined the effectiveness of a modified version of the Chronic Disease Self-Management Program called Living Well for individuals with serious mental illness. A total of 63 mental health consumers with serious mental illness and at least one concurrent chronic general medical condition were randomly assigned to receive the 13-session peer-cofacilitated Living Well intervention or usual care. Participants were evaluated on attitudinal, behavioral, and functional outcomes at baseline, at the end of the intervention, and at a two-month follow-up. Living Well participants showed significant postintervention improvements across a range of attitudinal (self-efficacy and patient activation), behavioral (illness self-management techniques), and functional (physical and emotional well-being and general health functioning) outcomes. Although attenuation of effect was observed for most outcomes at two months postintervention, evidence was found of continued improvement in general self-management behaviors (use of action planning, brainstorming, and problem-solving). Continued advantage was found for the Living Well group in other areas, such as health-related locus of control and reports of healthy eating and physical activity. Receipt of Living Well was associated with a notable decrease in use of the emergency room for medical care, although the between-group difference was not statistically significant. Living Well shows promise in helping mental health consumers more effectively manage chronic general medical conditions and experience improved functioning and well-being.

Objective The association of physical illness and mental health service use in older adults from racial/ethnic minority groups is an important area of study given the mental and physical health disparities and the low use of mental health services in this population. The purpose of this study is to describe the impact of comorbid physical illness on mental health service use and expenditures in older adults; and to evaluate disparities in mental health service use and expenditures among a racially/ethnically diverse sample of older adults with and without comorbid physical illness. Methods Data were obtained from the Medical Expenditure Panel Survey (years 2004–2011). The sample included 1563 whites, 519 African-Americans, and 642 Latinos and (N=2,724) aged 65+ with probable mental illness. Using two-part generalized linear models, we estimated and compared mental health service use among those with and without a comorbid physical illness. Results Mental health service use was greater for older adults with comorbid physical illness compared to those without a comorbid physical illness. Once mental health services were accessed, no differences in mental health expenditures were found. Comorbid physical illness increased the likelihood of mental health service use in older whites and Latinos. However, the presence of a comorbidity did not impact racial/ethnic disparities in mental health service use. Conclusions This study highlighted the important role of comorbid physical illness as a potential contributor to using mental health services and suggests intervention strategies to enhance engagement in mental health services by older adults from racial/ethnic minority groups.

In this issue, simultaneous differential equations were introduced. These differential equations are often used in the field of medical physics. The methods for solving them were also introduced, which include Laplace transform and matrix methods. Some examples were also introduced, in which Laplace transform and matrix methods were applied to solving simultaneous differential equations derived from a three-compartment kinetic model for analyzing the glucose metabolism in tissues and Bloch equations for describing the behavior of the macroscopic magnetization in magnetic resonance imaging.In the next (final) issue, partial differential equations and various methods for solving them will be introduced together with some examples in medical physics.

Elements of a cognitive model of physics problem solving: Epistemic games

Directory of Open Access Journals (Sweden)

Jonathan Tuminaro

2007-07-01

Full Text Available Although much is known about the differences between expert and novice problem solvers, knowledge of those differences typically does not provide enough detail to help instructors understand why some students seem to learn physics while solving problems and others do not. A critical issue is how students access the knowledge they have in the context of solving a particular problem. In this paper, we discuss our observations of students solving physics problems in authentic situations in an algebra-based physics class at the University of Maryland. We find that when these students are working together and interacting effectively, they often use a limited set of locally coherent resources for blocks of time of a few minutes or more. This coherence appears to provide the student with guidance as to what knowledge and procedures to access and what to ignore. Often, this leads to the students failing to apply relevant knowledge they later show they possess. In this paper, we outline a theoretical phenomenology for describing these local coherences and identify six organizational structures that we refer to as epistemic games. The hypothesis that students tend to function within the narrow confines of a fairly limited set of games provides a good description of our observations. We demonstrate how students use these games in two case studies and discuss the implications for instruction.

Physical and emotional abuse of children is a large scale problem in South Africa, with severe negative outcomes for survivors. Although chronic household illness has shown to be a predictor for physical and emotional abuse, no research has thus far investigated the different pathways from household chronic illness to child abuse victimisation in South Africa. Confidential self-report questionnaires using internationally utilised measures were completed by children aged 10-17 (n = 3515, 56.7% female) using door-to-door sampling in randomly selected areas in rural and urban locations of South Africa. Follow-up surveys were conducted a year later (96.7% retention rate). Using multiple mediation analyses, this study investigated direct and indirect effects of chronic household illness (AIDS or other illness) on frequent (monthly) physical and emotional abuse victimisation with poverty and extent of the ill person's disability as hypothesised mediators. For children in AIDS-ill families, a positive direct effect on physical abuse was obtained. In addition, positive indirect effects through poverty and disability were established. For boys, a positive direct and indirect effect of AIDS-illness on emotional abuse through poverty were detected. For girls, a positive indirect effect through poverty was observed. For children in households with other chronic illness, a negative indirect effect on physical abuse was obtained. In addition, a negative indirect effect through poverty and positive indirect effect through disability was established. For boys, positive and negative indirect effects through poverty and disability were found respectively. For girls, a negative indirect effect through poverty was observed. These results indicate that children in families affected by AIDS-illness are at higher risk of child abuse victimisation, and this risk is mediated by higher levels of poverty and disability. Children affected by other chronic illness are at lower risk for

Social anxiety (SA) is a frequent comorbid condition in patients with mental illness. However, no data exist regarding SA in physical activity (PA) situations. The aim of the present study was to measure the level of self-reported SA in PA participation in patients with mental illness compared to healthy controls. Six hundred ninety-three patients with mental illness and 2,888 controls aged between 18 and 65 years completed the Physical Activity and Sport Anxiety Scale (PASAS). Group and gender differences in PASAS scores were tested by ANOVA and Scheffé's post hoc test. After controlling for gender (P mental illness reported higher levels of SA in PA situations compared to healthy control subjects. Health professionals should consider SA when trying to improve outcome and adherence of patients with mental illness to PA interventions. © 2013 Wiley Periodicals, Inc.

The opinions of Turkish mental health nurses on physical health care for individuals with mental illness: A qualitative study.

Çelik Ince, S; Partlak Günüşen, N; Serçe, Ö

2018-05-01

Individuals with mental illness have significantly higher mortality and morbidity than the general population due to physical illnesses. Mental health nurses play a key role in providing care for common physical problems and protecting and promoting healthy lifestyles. Little is known from previous studies in the international literature about the attitudes, behaviours and thoughts of mental health nurses on providing physical health care. Mental health nurses mostly focus on the existing physical health problems of individuals with mental illness. However, mental health nurses do not include practices of disease prevention and physical health promotion for individuals with mental illness. The desire to see positive changes in individuals with mental illness, receiving positive feedback, feeling useful and happy, and feeling satisfied with their profession motivate mental health nurses in terms of providing physical health care. The knowledge and skill required of mental health nurses to provide physical health care need to be increased. Institutions should employ expert nurses who are able to guide mental health nurses to provide physical health care. It is important to provide adequate physical infrastructure and human resources to provide better physical health care in mental health services. Background Mental health nurses play an important role in improving the physical health of individuals with mental illnesses. However, there are limited studies of their attitudes and practices about physical health. Therefore, there is a need for qualitative studies to clarify the issue. The aim of this study was to determine mental health nurses' opinions about physical health care for individuals with mental illness. This study was carried out in Turkey. A qualitative descriptive approach was taken in the study. The sample consisted of twelve mental health nurses selected by purposeful sampling. In-depth interviews were conducted using a semi-structured interview format

This study investigated cardio-metabolic risk factors among patients with severe mental illness who do or do not meet the recommendations of 150min per week of physical activity. A secondary aim was to assess whether those that do meet the recommendations report lower levels of mental health symptoms. 107 (60♀) Ugandan in- and outpatients (mean age=34.4 ± 9.7 years) with severe mental illness (depression=7, bipolar disorder=55, schizophrenia=45) completed the Physical Activity Vital Sign (PAVS) method and Brief Symptoms Inventory -18. Participants were also screened for abdominal obesity (waist circumference>90cm), overweight (body mass index≥25) and hypertension (systolic pressure≥140mmHg and/or diastolic pressure≥90mmHg).48.6% (n = 52) of patients met the physical activity recommendations as assessed by the PAVS method. 41.1% (n = 44) were overweight, 40.2% (n = 43) had abdominal obesity and 23.4% (n = 25) had hypertension. Those who did not meet the physical activity recommendations were significantly older, had a higher BSI-18 somatisation score, and had a higher risk of overweight [relative risk (RR) = 2.88, 95% confidence interval (CI) = 1.59-4.99], abdominal obesity (RR = 1.82, 95%CI = 1.13-2.93), and hypertension (RR = 2.16, 95%CI = 0.99-4.73). The PAVS is a feasible method of assessing physical activity among patients with severe mental illness in a low resource setting. The PAVS may have clinical utility for physical and mental health risk stratification. Copyright © 2017 Elsevier B.V. All rights reserved.

A SiQuENC for solving physics problems

Liao, David

2018-04-01

Students often struggle in AP Physics 1 because they have not been previously trained to develop qualitative arguments. Extensive literature on multiple representations and qualitative reasoning provides strategies to address this challenge. Table I presents three examples, including SiQuENC, which I adapted from a strategy promoted by Etkina et al. To remind students that they can use qualitative reasoning (e.g., arguing from proportionalities), rather than relying only on algebra, I replaced "Solve" with "Analyze." I added a "Communicate" step to guide planning of written responses to AP Physics 1 and 2 questions. To perform this step, draw a circled number around each key point identified in figures, equations, and sentence fragments. Then, convert numbered points into sentences.

MAUVE: A New Strategy for Solving and Grading Physics Problems

Science.gov (United States)

Hill, Nicole Breanne

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.

The World Health Organization Quality of Life (WHOQOL-100) questionnaire is a generic quality of life (QoL) measurement tool used in various cultural and social settings and across different patient and healthy populations. The present study examines the psychometric properties of the Greek version, with an emphasis on the ability of the instrument to capture QoL differences between mentally ill, physically ill and healthy individuals. A total of 425 Caucasian participants were tested, as to form 3 groups: (a) 124 psychiatric patients (schizophrenia n = 87, alcohol abuse/dependence n = 37), (b) 234 patients with physical illness (hypertension n = 139, cancer n = 95), and (c) 67 healthy control individuals. Confirmatory factor analysis was performed indicating that a four-factor model can provide an adequate instrument structure for the participating groups (GFI 0.92). Additionally, internal consistency of the instrument was shown to be acceptable, with Cronbach's alpha values ranging from 0.78 to 0.90 regarding the four -domain model, and from 0.40 to 0.90 regarding the six-domain one. Evidence based on Pearson's r and Independent samples t-test indicated satisfactory test/retest reliability, as well as good convergent validity tested with the General Health Questionnaire (GHQ-28) and the Life Satisfaction Inventory (LSI). Furthermore, using Independent samples t-test and one-way ANOVA, the instrument demonstrated good discriminatory ability between healthy, mentally ill and physically ill participants, as well as within the distinct patient groups of schizophrenic, alcohol dependent, hypertensive and cancer patients. Healthy individuals reported significantly higher QoL, particularly in the physical health domain and in the overall QoL/health facet. Mentally ill participants were distinctively differentiated from physically ill in several domains, with the greatest difference and reduction observed in the social relationships domain and in the overall Qo

Sedentary behaviour and lack of physical activity threatens health. Research concerning these behaviours of inpatients with severe mental illness is limited but urgently needed to reveal prevalence and magnitude. In total, 184 inpatients (men n =108, women n =76, mean age 57,4, 20% first generation antipsychotics, 40% second generation antipsychotics, 43% antidepressants, mean years hospitalisation 13 years), with severe mental illness of a Dutch psychiatric hospital wore an accelerometer for five days to objectively measure total activity counts per hour and percentages in sedentary behaviour, light intensity physical activity and moderate to vigorous physical activity. Accelerometer data were compared with data of 54 healthy ward employees. Patients showed significantly less activity counts per hour compared to employees (p=0.02), although the differences were small (d=0.32). Patients were sedentary during 84% of the wear time (50min/h), spend 10% in light intensity physical activity and 6% in moderate to vigorous physical activity. Age was the only significant predictor, predicting less total activity counts/h in higher ages. Decreasing sedentary behaviour and improving physical activity in this population should be a high priority in clinical practice. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

Agius, Mark; Aquilina, Francesca Falzon

This article aims at addressing the implications of defining 'comorbidity' within the field of psychiatry. We have looked at the standard definition of comorbidity and then discussed whether this definition can be applied to comorbidities in psychiatry. While comorbidities in physical illness are clearly the coexistence of two independent illnesses, Comorbidities in Mental illness are the result of the polygenic nature of mental illnesses, especially in psychotic illness whether schizophrenia or bipolar disorder. As a consequence, often the comorbidities of psychiatric illness are caused by two conditions which have in common the presence of particular single nucleotide polymorphisms (snps), which regulate the metabolism of neurotransmitters or the presence of neurotrophic factors . Thus inevitably, many such comorbidities are inextricably linked. We discuss the consequences of this form of comorbidity for the description, classification, and risk profile of mental illness.

This book shows the capabilities of Microsoft Excel in teaching physical sciences statistics effectively. Similar to the previously published Excel 2010 for Physical Sciences Statistics, this book is a step-by-step exercise-driven guide for students and practitioners who need to master Excel to solve practical science problems. If understanding statistics isn’t your strongest suit, you are not especially mathematically-inclined, or if you are wary of computers, this is the right book for you. Excel, a widely available computer program for students and managers, is also an effective teaching and learning tool for quantitative analyses in science courses. Its powerful computational ability and graphical functions make learning statistics much easier than in years past. However, Excel 2013 for Physical Sciences Statistics: A Guide to Solving Practical Problems is the first book to capitalize on these improvements by teaching students and managers how to apply Excel to statistical techniques necessary in their ...

Relationships between undergraduates' argumentation skills, conceptual quality of problem solutions, and problem solving strategies in introductory physics

Science.gov (United States)

Rebello, Carina M.

This study explored the effects of alternative forms of argumentation on undergraduates' physics solutions in introductory calculus-based physics. A two-phase concurrent mixed methods design was employed to investigate relationships between undergraduates' written argumentation abilities, conceptual quality of problem solutions, as well as approaches and strategies for solving argumentative physics problems across multiple physics topics. Participants were assigned via stratified sampling to one of three conditions (control, guided construct, or guided evaluate) based on gender and pre-test scores on a conceptual instrument. The guided construct and guided evaluate groups received tasks and prompts drawn from literature to facilitate argument construction or evaluation. Using a multiple case study design, with each condition serving as a case, interviews were conducted consisting of a think-aloud problem solving session paired with a semi-structured interview. The analysis of problem solving strategies was guided by the theoretical framework on epistemic games adapted by Tuminaro and Redish (2007). This study provides empirical evidence that integration of written argumentation into physics problems can potentially improve the conceptual quality of solutions, expand their repertoire of problem solving strategies and show promise for addressing the gender gap in physics. The study suggests further avenues for research in this area and implications for designing and implementing argumentation tasks in introductory college physics.

The poor physical health of people who experience severe mental illness (SMI) is an important public health issue that has been acknowledged, yet not properly addressed. People who live with SMI perform a myriad of complex tasks in order to take care of their physical health, while receiving unpredictable levels of support and assistance from health professionals. In this qualitative study, we aimed to uncover the kinds of work people with SMI do in order to look after their physical health. In a metropolitan area in Queensland, Australia, 32 people with lived experience of SMI participated in semi-structured, face-to-face interviews. Data were digitally recorded, transcribed verbatim and open coded. They were then themed using a constant comparative process. We found that people with SMI were engaged in a "rhythm of life with illness" that consisted of relatively short, acute and chaotic cycles of mental and physical illness, accompanied by much longer mental and physical illness recovery cycles. Participants engaged in three specific types of health-related work to manage these cycles: discovery work (and the associated role of the health professional); sense-making work to meaningfully interpret health and illness; and embedding work to become engaged self-managers of illness and producers of health. We discuss how varying levels of support from health professionals impact consumers' self-management of their physical and mental health; how health professionals influence consumers' experience of treatment burden; and implications for practice. © 2017 John Wiley & Sons Ltd.

A conceptual model of independence and dependence for adults with chronic physical illness and disability.

Science.gov (United States)

Gignac, M A; Cott, C

1998-09-01

This paper presents a conceptual model of physical independence and dependence as it relates to adult onset, chronic physical illness and disability. Physical independence and dependence are presented as two separate, continuous, and multiply determined constructs, and illustrations are provided of situations where people can be independent, dependent, not independent, or experience imposed dependence. The paper also discusses potential determinants of physical independence and dependence, including different domains of disability, the role of subjective perceptions, demographics, the physical and social/political environments, personal resources, attitudes and coping resources, illness and efficacy appraisals, and the nature of the assistive relationship. The paper extends work on physical independence and dependence by synthesizing the findings from previous studies and incorporating the findings from other relevant areas of research into the area. It also expands on the concepts of physical independence and dependence, as well as their determinants, and relates independence and dependence to other outcomes of interest such as service delivery.

Restraining therapies (physical or pharmacological) are used to promote the safety of both patients and health care workers. Some guidelines recommend nonpharmacological or pharmacological interventions be used before physical restraints in critically ill patients. To characterize psychotropic drug interventions before and after use of physical restraints in critically ill adults receiving mechanical ventilation. A single-center, prospective, observational study documenting psychotropic drug use and Sedation-Agitation Scale (SAS) scores in the 2 hours before and the 6 hours after application of physical restraints. Ninety-three patients were restrained for a median of 21 hours (interquartile range, 9-70 hours). Thirty percent of patients did not receive a psychotropic drug or had a drug stopped or decreased before physical restraints were applied. More patients received a psychotropic drug intervention after use of physical restraints than before (86% vs 56%, P = .001). Administration of opioids was more common after the use of physical restraints (54% vs 20% of patients, P = .001) and accounted for more drug interventions (45% vs 29%, P = .001). Fifty patients had SAS scores from both time periods; 16% remained oversedated, 24% were appropriately sedated, and 16% remained agitated in both time periods. Patients became oversedated (20%), more agitated (10%), less agitated (8%), and less sedated (6%) after restraint use. Psychotropic drug interventions (mostly using opioids) were more common after use of physical restraints. Some patients may be physically restrained for anticipated treatment interference without consideration of pharmacological options and without documented agitation. ©2017 American Association of Critical-Care Nurses.

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

Individuals with serious mental illness endorse many more medical and psychosocial barriers to physical activity (PA) than the general population. However, it is unknown if older adults with serious mental illness are at greater risk of experiencing barriers to PA than their younger counterparts. The present study utilized a national VA dataset to compare veterans with serious mental illness ages 55 and older (n = 9,044) to veterans with serious mental illness ages 54 and younger (n = 8,782) on their responses to a questionnaire assessment of barriers to PA. Older veterans were more likely to endorse arthritis and cardiopulmonary disease, and less likely to endorse work schedule, as barriers to PA. Interventions designed to increase PA for young/middle-aged adults with serious mental illness may be broadly useful for older adults with serious mental illness, with some modification to address specific health concerns.

Happell, Brenda; Platania-Phung, Chris; Scott, David

2013-10-01

People with serious mental illness have increased rates of physical ill-health and reduced contact with primary care services. In Australia, the Mental Health Nurse Incentive Program (MHNIP) was developed to facilitate access to mental health services. However, as a primary care service, the contribution to physical health care is worthy of consideration. Thirty-eight nurses who were part of the MHNIP participated in a national survey of nurses working in mental health about physical health care. The survey invited nurses to report their views on the physical health of consumers and the regularity of physical health care they provide. Physical health-care provision in collaboration with general practitioners (GPs) and other health-care professionals was reported as common. The findings suggest that the MHNIP provides integrated care, where nurses and GPs work in collaboration, allowing enough time to discuss physical health or share physical health activities. Consumers of this service appeared to have good access to physical and mental health services, and nurses had access to primary care professionals to discuss consumers' physical health and develop their clinical skills in the physical domain. The MHNIP has an important role in addressing physical health concerns, in addition to the mental health issues of people accessing this service. © 2012 The Authors; International Journal of Mental Health Nursing © 2012 Australian College of Mental Health Nurses Inc.

What Is Physics Problem-Solving Competency? The Views of Arnold Sommerfeld and Enrico Fermi

Science.gov (United States)

Niss, Martin

2018-05-01

A central goal of physics education is to teach problem-solving competency, but the description of the nature of this competency is somehwat fragmentary and implicit in the literature. The present article uses recent historical scholarship on Arnold Sommerfeld and Enrico Fermi to identify and characterize two positions on the nature of physics problem-solving competency. The first, Sommerfeld's, is a "theory first, phenomenon second" approach. Here, the relevant problems originate in one of the theories of physics and the goal of the problem-solver is to make a mathematical analysis of the relevant equation(s) and then give a qualitative analysis of the phenomenon that arise from these mathematical results. Fermi's position is a "phenomenon first, theory second" approach, where the starting point is a physical phenomenon that is analyzed and then brought into the realm of a physics theory. The two positions are illustrated with solutions to two problems and it is shown that the two positions are reflected in problem collections of university educations in physics.

Impact of Guided Reflection with Peers on the Development of Effective Problem Solving Strategies and Physics Learning

Science.gov (United States)

Mason, Andrew J.; Singh, Chandralekha

2016-05-01

Students must learn effective problem solving strategies in order to develop expertise in physics. Effective problem solving strategies include a conceptual analysis of the problem followed by planning of the solution, and then implementation, evaluation, and reflection upon the process. Research suggests that converting a problem from the initial verbal representation to other suitable representation, e.g., diagrammatic representation, during the initial conceptual analysis can facilitate further analysis of the problem. But without guidance, many introductory physics students solve problems using superficial clues and cues and do not perceive problem solving as an opportunity for learning. Here, we describe a study that suggests that engaging students in reflection with peers about effective problem solving strategies while effective approaches are modeled for them and prompt feedback is provided may enhance desirable skills.

Role of beliefs and emotions in numerical problem solving in university physics education

Science.gov (United States)

Bodin, Madelen; Winberg, Mikael

2012-06-01

Numerical problem solving in classical mechanics in university physics education offers a learning situation where students have many possibilities of control and creativity. In this study, expertlike beliefs about physics and learning physics together with prior knowledge were the most important predictors of the quality of performance of a task with many degrees of freedom. Feelings corresponding to control and concentration, i.e., emotions that are expected to trigger students’ intrinsic motivation, were also important in predicting performance. Unexpectedly, intrinsic motivation, as indicated by enjoyment and interest, together with students’ personal interest and utility value beliefs did not predict performance. This indicates that although a certain degree of enjoyment is probably necessary, motivated behavior is rather regulated by integration and identification of expertlike beliefs about learning and are more strongly associated with concentration and control during learning and, ultimately, with high performance. The results suggest that the development of students’ epistemological beliefs is important for students’ ability to learn from realistic problem-solving situations with many degrees of freedom in physics education.

The purpose of this study was to develop a multi-disciplinary self-management intervention based on empowerment theory and to evaluate the effectiveness of the intervention for older adults with chronic illness. A randomized controlled trial design was used with 43 Korean older adults with chronic illness (Experimental group=22, Control group=21). The intervention consisted of two phases: (1) 8-week multi-disciplinary, team guided, group-based health education, exercise session, and individual empowerment counseling, (2) 16-week self-help group activities including weekly exercise and group discussion to maintain acquired self-management skills and problem-solving skills. Baseline, 8-week, and 24-week assessments measured health empowerment, exercise self-efficacy, physical activity, and physical function. Health empowerment, physical activity, and physical function in the experimental group increased significantly compared to the control group over time. Exercise self-efficacy significantly increased in experimental group over time but there was no significant difference between the two groups. The self-management program based on empowerment theory improved health empowerment, physical activity, and physical function in older adults. The study finding suggests that a health empowerment strategy may be an effective approach for older adults with multiple chronic illnesses in terms of achieving a sense of control over their chronic illness and actively engaging self-management.

Development of a problem solving evaluation instrument; untangling of specific problem solving assets

Science.gov (United States)

Adams, Wendy Kristine

The purpose of my research was to produce a problem solving evaluation tool for physics. To do this it was necessary to gain a thorough understanding of how students solve problems. Although physics educators highly value problem solving and have put extensive effort into understanding successful problem solving, there is currently no efficient way to evaluate problem solving skill. Attempts have been made in the past; however, knowledge of the principles required to solve the subject problem are so absolutely critical that they completely overshadow any other skills students may use when solving a problem. The work presented here is unique because the evaluation tool removes the requirement that the student already have a grasp of physics concepts. It is also unique because I picked a wide range of people and picked a wide range of tasks for evaluation. This is an important design feature that helps make things emerge more clearly. This dissertation includes an extensive literature review of problem solving in physics, math, education and cognitive science as well as descriptions of studies involving student use of interactive computer simulations, the design and validation of a beliefs about physics survey and finally the design of the problem solving evaluation tool. I have successfully developed and validated a problem solving evaluation tool that identifies 44 separate assets (skills) necessary for solving problems. Rigorous validation studies, including work with an independent interviewer, show these assets identified by this content-free evaluation tool are the same assets that students use to solve problems in mechanics and quantum mechanics. Understanding this set of component assets will help teachers and researchers address problem solving within the classroom.

The impact of lifestyle factors on the physical health of people with a mental illness: a brief review.

People with a mental illness are much more likely to experience poor physical health when compared to the general population, showing a higher propensity to develop the metabolic syndrome. Past focus has predominantly been upon individuals treated with antipsychotics, yet poor physical health is occurring across diagnoses. The purpose of this paper is to draw attention to the major factors within the domain of lifestyle in order to support the need for more detailed and rigorous physical health assessment and ongoing monitoring for people with a mental illness. This paper reviews existing evidence relating to lifestyle factors such as low exercise levels, poor diet and nutrition, high cholesterol levels, tobacco smoking and poor dental care, contributing to poor physical health such as a higher incidence of cardiovascular disease and type 2 diabetes. An integrative review was conducted from a multi-disciplinary search of online databases and journals, focusing upon mental illness and lifestyle issues predominant in the literature. The findings reviewed here suggest that greater attention should be paid to the physical health assessment and ongoing monitoring of all people with mental health disorders so that preventable illness does not result in higher levels of morbidity and mortality for this disadvantaged population. Early identification aids preventive interventions and assists clinicians and mental health staff to more effectively treat emergent physical health problems.

To determine effects of physical activity on depressive symptoms (primary objective), symptoms of schizophrenia, anthropometric measures, aerobic capacity, and quality of life (secondary objectives) in people with mental illness and explore between-study heterogeneity. MEDLINE, Cochrane Controlled Trials Register, PsycINFO, CINAHL, Embase, and the Physiotherapy Evidence Database (PEDro) were searched from earliest record to 2013. Randomized controlled trials of adults with a DSM-IV-TR, ICD-10, or clinician-confirmed diagnosis of a mental illness other than dysthymia or eating disorders were selected. Interventions included exercise programs, exercise counseling, lifestyle interventions, tai chi, or physical yoga. Study methodological quality and intervention compliance with American College of Sports Medicine (ACSM) guidelines were also assessed. Two investigators extracted data. Data were pooled using random-effects meta-analysis. Meta-regression was used to examine sources of between-study heterogeneity. Thirty-nine eligible trials were identified. The primary meta-analysis found a large effect of physical activity on depressive symptoms (n = 20; standardized mean difference (SMD) = 0.80). The effect size in trial interventions that met ACSM guidelines for aerobic exercise did not differ significantly from those that did not meet these guidelines. The effect for trials with higher methodological quality was smaller than that observed for trials with lower methodological quality (SMD = 0.39 vs 1.35); however, the difference was not statistically significant. A large effect was found for schizophrenia symptoms (SMD = 1.0), a small effect was found for anthropometry (SMD = 0.24), and moderate effects were found for aerobic capacity (SMD = 0.63) and quality of life (SMD = 0.64). Physical activity reduced depressive symptoms in people with mental illness. Larger effects were seen in studies of poorer methodological quality. Physical activity reduced symptoms of

Partial differential equations are often used in the field of medical physics. In this (final) issue, the methods for solving the partial differential equations were introduced, which include separation of variables, integral transform (Fourier and Fourier-sine transforms), Green's function, and series expansion methods. Some examples were also introduced, in which the integral transform and Green's function methods were applied to solving Pennes' bioheat transfer equation and the Fourier series expansion method was applied to Navier-Stokes equation for analyzing the wall shear stress in blood vessels.Finally, the author hopes that this series will be helpful for people who engage in medical physics.

Military sexual trauma as a determinant in the development of mental and physical illness in male and female veterans.

Science.gov (United States)

O'Brien, Betsy S; Sher, Leo

2013-01-01

Military Sexual Trauma (MST) is defined as sexual harassment and or sexual assault experienced by a military service member. It is much more widespread and common than reported. It is associated with pre-combat traumatic experiences and pathologic sequelae including mental and medical illness. An electronic search of the major behavioral science databases was conducted to retrieve studies detailing the social, epidemiological and clinical characteristics of MST and its relationship to psychiatric and medical illness. Studies indicate that military sexual trauma is related to an increase in psychiatric pathology, including posttraumatic stress disorder (PTSD), substance abuse and dependence, depression, anxiety, eating disorders and suicidal behavior. MST is also related to an increase in medical illness, primarily pain-related symptoms involving multiple organ systems, including gastrointestinal, neurological, genitourinary and musculoskeletal. MST is associated with an increased prevalence of mental and physical illness. Although there are some gender differences in the reported rates of MST and there may be some variables, such as prior traumatic experiences, that may make an individual more vulnerable to the psychiatric and medical sequela of MST, it is clear that MST is a major healthcare issue that affects both sexes and warrants further attention and an increase in clinical resources devoted to it. Some preventive measures for decreasing the prevalence of MST may include increasing education and legal prosecution of perpetrators in the military, and increasing access to mental health services for individuals who have suffered from MST.

Iterative tensor voting for perceptual grouping of ill-defined curvilinear structures.

Science.gov (United States)

Loss, Leandro A; Bebis, George; Parvin, Bahram

2011-08-01

In this paper, a novel approach is proposed for perceptual grouping and localization of ill-defined curvilinear structures. Our approach builds upon the tensor voting and the iterative voting frameworks. Its efficacy lies on iterative refinements of curvilinear structures by gradually shifting from an exploratory to an exploitative mode. Such a mode shifting is achieved by reducing the aperture of the tensor voting fields, which is shown to improve curve grouping and inference by enhancing the concentration of the votes over promising, salient structures. The proposed technique is validated on delineating adherens junctions that are imaged through fluorescence microscopy. However, the method is also applicable for screening other organisms based on characteristics of their cell wall structures. Adherens junctions maintain tissue structural integrity and cell-cell interactions. Visually, they exhibit fibrous patterns that may be diffused, heterogeneous in fluorescence intensity, or punctate and frequently perceptual. Besides the application to real data, the proposed method is compared to prior methods on synthetic and annotated real data, showing high precision rates.

Inhibitory Control, but Not Prolonged Object-Related Experience Appears to Affect Physical Problem-Solving Performance of Pet Dogs

Human infants develop an understanding of their physical environment through playful interactions with objects. Similar processes may influence also the performance of non-human animals in physical problem-solving tasks, but to date there is little empirical data to evaluate this hypothesis. In addition or alternatively to prior experiences, inhibitory control has been suggested as a factor underlying the considerable individual differences in performance reported for many species. Here we report a study in which we manipulated the extent of object-related experience for a cohort of dogs (Canis familiaris) of the breed Border Collie over a period of 18 months, and assessed their level of inhibitory control, prior to testing them in a series of four physical problem-solving tasks. We found no evidence that differences in object-related experience explain variability in performance in these tasks. It thus appears that dogs do not transfer knowledge about physical rules from one physical problem-solving task to another, but rather approach each task as a novel problem. Our results, however, suggest that individual performance in these tasks is influenced in a complex way by the subject’s level of inhibitory control. Depending on the task, inhibitory control had a positive or a negative effect on performance and different aspects of inhibitory control turned out to be the best predictors of individual performance in the different tasks. Therefore, studying the interplay between inhibitory control and problem-solving performance will make an important contribution to our understanding of individual and species differences in physical problem-solving performance.

The life expectancy of adults with mental illness is significantly less than that of the general population, and this is largely due to poor physical health. Behavioural counselling can improve physical health indicators among people with non-communicable disease. This repeated-measures, single-group intervention trial evaluated the effects of a 19-week behavioural counselling programme on metabolic health indicators and physical activity levels of outpatient adults with mental illness. Sixteen participants completed the intervention that comprised individual face-to-face counselling sessions with a registered nurse every 3 weeks, and progress reviews with a medical practitioner every 6 weeks. Assessment included self-report and objective measurement of physical activity, and measures of blood pressure and anthropometry. Statistically-significant changes were demonstrated between baseline and post intervention for participants' waist circumference (P = 0.035) and waist-to-height ratio (P = 0.037). Non-significant improvements were demonstrated in weight and physical activity. The findings indicated that adults with mental illness can engage in a nurse-led behavioural counselling intervention, with improvements in some metabolic health measures after 19 weeks. It is recommended that behavioural counselling programmes for adults with mental illness be sustained over time and have an 'open door' policy to allow for attendance interruptions, such as hospitalization. © 2017 Australian College of Mental Health Nurses Inc.

Solving Large-Scale Computational Problems Using Insights from Statistical Physics

Energy Technology Data Exchange (ETDEWEB)

Selman, Bart [Cornell University

2012-02-29

Many challenging problems in computer science and related fields can be formulated as constraint satisfaction problems. Such problems consist of a set of discrete variables and a set of constraints between those variables, and represent a general class of so-called NP-complete problems. The goal is to find a value assignment to the variables that satisfies all constraints, generally requiring a search through and exponentially large space of variable-value assignments. Models for disordered systems, as studied in statistical physics, can provide important new insights into the nature of constraint satisfaction problems. Recently, work in this area has resulted in the discovery of a new method for solving such problems, called the survey propagation (SP) method. With SP, we can solve problems with millions of variables and constraints, an improvement of two orders of magnitude over previous methods.

The present study extends earlier research identifying an increased risk of anxiety among children with chronic physical illness (CwCPI) by examining a more complete model that explains how physical illness leads to increased symptoms of anxiety and depression. We tested a stress-generation model linking chronic physical illness to symptoms of anxiety and depression in a population-based sample of children aged 10 to 15 years. We hypothesized that having a chronic physical illness would be associated with more symptoms of anxiety and depression, increased levels of maternal depressive symptoms, more family dysfunction, and lower self-esteem; and, that maternal depressive symptoms, family dysfunction, and child self-esteem would mediate the influence of chronic physical illness on symptoms of anxiety and depression. Data came from the National Longitudinal Survey of Children and Youth (N = 10,646). Mediating processes were analyzed using latent growth curve modeling. Childhood chronic physical illness was associated with increases in symptoms of anxiety and depression, β = 0.20, p self-esteem, and in turn, increases in symptoms of anxiety and depression. CwCPI are at-risk for symptoms of anxiety and depression. Some of this elevated risk appears to work through family processes and child self-esteem. This study supports the use of family-centered care approaches among CwCPI to minimize burden on families and promote healthy psychological development for children.

The study investigated the relationship among physical abuse, positive psychological factors including emotional competence and social problem-solving, and suicidal ideation among adolescents in China. The possible moderating effects of emotional competence and social problem-solving in the association between physical abuse and adolescent suicidal ideation were also studied. A cross-sectional survey employing convenience sampling was conducted and self-administered questionnaires were collected from 527 adolescents with mean age of 14 years from the schools in Shanghai. Results showed that physical abuse was significantly and positively related to suicidal ideation in both male and female adolescents. Emotional competence was not found to be significantly associated with adolescent suicidal ideation, but rational problem-solving, a sub-scale of social problem-solving, was shown to be significantly and negatively associated with suicidal ideation for males, but not for females. However, emotional competence and rational problem-solving were shown to be a significant and a marginally significant moderator in the relationship between physical abuse and suicidal ideation in females respectively, but not in males. High rational problem-solving buffered the negative impact of physical abuse on suicidal ideation for females. Interestingly, females with higher empathy and who reported being physically abused by their parents have higher suicidal ideation. Findings are discussed and implications are stated. It is suggested to change the attitudes of parents on the concept of physical abuse, guide them on appropriate attitudes, knowledge and skills in parenting, and enhance adolescents' skills in rational problem-solving.

Full Text Available Abstract Awareness of the importance of maintaining physical health for patients with severe mental illnesses has recently been on the increase. Although there are several elements contributing to poor physical health among these patients as compared with the general population, risk factors for cardiovascular disease such as smoking, diabetes mellitus, hypertension, dyslipidemia, metabolic syndrome, and obesity are of particular significance due to their relationship with mortality and morbidity. These patients present higher vulnerability to cardiovascular risk factors based on several issues, such as genetic predisposition to certain pathologies, poor eating habits and sedentary lifestyles, high proportions of smokers and drug abusers, less access to regular health care services, and potential adverse events during pharmacological treatment. Nevertheless, there is ample scientific evidence supporting the benefits of lifestyle interventions based on diet and exercise designed to minimize and reduce the negative impact of these risk factors on the physical health of patients with severe mental illnesses.

In 878 patients with cancer, rheumatological diseases, multiple sclerosis, inflammatory bowel disease, and glaucoma, we assessed psychological distress (SCL-90 and GHQ-28, quality of life (WHOQOL-BREF, interpersonal difficulties (IIP-40, hostility (HDHQ, and defense styles (DSQ. Narcissistic rage comprised DSQ “omnipotence” and HDHQ “extraverted hostility”. Hierarchical multiple regressions analyses were performed. We showed that, in patients with disease duration less than one year, narcissistic rage had a minor impact on psychosocial variables studied, indicating that the rage was rather part of a “normal” mourning process. On the contrary, in patients with longer disease duration, increased rates of narcissistic rage had a great impact on all outcome variables, and the opposite was true for patients with low rates of narcissistic rage, indicating that narcissistic rage constitutes actually an “Achilles’ Heel” for patients with long-term physical illness. These findings may have important clinical implications.Keywords: consultation-liaison psychiatry, psychosomatics, narcissism, physical illness, quality of life, psychological distress, personality

There is compelling evidence that the physical health of people with severe mental illness is poor. Health-promotion guidelines have been recommended as a mechanism for improving the physical health of this population. However, there are significant barriers to the adoption of evidence-based guidelines in practice. The purpose of this research was to apply existing implementation theories to examine the capability of the health system to integrate physical health promotion into mental health service delivery. Data were collected within a regional city in Queensland, Australia. Fifty participants were interviewed. The core theme that emerged from the data was that of 'care boundaries' that influenced the likelihood of guidelines being implemented. Boundaries existed around the illness, care provision processes, sectors, the health-care system, and society. These multilevel boundaries, combined with participants' ways of responding to them, impacted on capability (i.e. the ability to integrate physical health promotion into existing practices). Participants who were able to identify strategies to mediate these boundaries were better positioned to engage with physical health-promotion practice. Thus, the implementation of evidence-based guidelines depended heavily on the capability of the workforce to develop and adopt boundary-mediating strategies. © 2013 Australian College of Mental Health Nurses Inc.

The aim of the study was to elicit the views and opinions of people diagnosed with serious mental illness in relation to physical activity. Ten people who were attending a community mental health centre participated in semi-structured interviews. The main results showed that participants found physical activity beneficial in terms of psychological and social well-being and perceived clear gains in relation to recovery and quality of life. Physical activity should be routinely included in plans of care and mental health policy guidelines globally should contain physical activity as a key component. Mental health policy guidelines globally should contain physical activity as a key component. The aim of the current study was to explore the subjective experiences of people diagnosed with serious mental illness (SMI) in relation to physical activity. The study was conducted using a qualitative exploratory descriptive approach. The participants (n = 10), who were outpatients attending a day centre, were interviewed to elicit their views and opinions about physical activity. The data were thematically analysed using a recognized framework. The main themes that emerged included physical activity as a meaningful activity, physical activity as a mental activity, quality of life and recovery, and perceived challenges to physical activity. The unique perspectives of service users provides fresh insights on the topic and the findings support the justification for the inclusion of physical activity in plans of care and to be contained in global mental health policy directives. © 2014 John Wiley & Sons Ltd.

The combination of modern computing power, the interactivity of web applications, and the flexibility of object-oriented programming may finally be sufficient to create computer coaches that can help students develop metacognitive problem-solving skills, an important competence in our rapidly changing technological society. However, no matter how effective such coaches might be, they will only be useful if they are attractive to students. We describe the design and testing of a set of web-based computer programs that act as personal coaches to students while they practice solving problems from introductory physics. The coaches are designed to supplement regular human instruction, giving students access to effective forms of practice outside class. We present results from large-scale usability tests of the computer coaches and discuss their implications for future versions of the coaches.

Defining the neurotoxin derived illness chronic ciguatera using markers of chronic systemic inflammatory disturbances: a case/control study.

Science.gov (United States)

Shoemaker, Ritchie C; House, Dennis; Ryan, James C

2010-01-01

Ciguatoxins are extremely potent neurotoxins, produced by tropical marine dinoflagellates, that persistently enter into our food web. Over 100,000 people annually experience acute ciguatera poisoning from consuming toxic fish. Roughly 5% of these victims will develop chronic ciguatera (CC), a widespread, multisymptom, multisystem, chronic illness that can last tens of years. CC is marked by disproportionate disability and non-specific refractory symptoms such as fatigue, cognitive deficits and pain, and is suggestive of other illnesses. Its unknown pathophysiology makes both diagnosis and treatment difficult. We wanted to compare objective parameters of visual contrast sensitivity testing, measures of innate immune response and genetic markers in cases to controls to assess the potential for the presence of persistent inflammatory parameters that are demonstrated in other biotoxin associated illnesses at a single specialty clinic. Using 59 CC cases and 59 controls we present in retrospective review, in all cases, abnormalities in immune responses paralleling the chronic systemic inflammatory response syndrome seen in several other chronic diseases. This study defines a preliminary case definition using medical history, total symptoms, visual contrast sensitivity, HLA DR genotype analysis, reduction of regulatory neuropeptides VIP and MSH, and multiple measures of inflammatory immune response, especially C4a and TGFβ1, thereby providing a basis for identification and targeted therapy. CC provides a model for chronic human illness associated with initiation of inflammatory responses by biologically produced neurotoxins. Copyright © 2010 Elsevier Inc. All rights reserved.

This study examined the rates of anxiety and depressive disorders, physical illnesses, and health service use in male patients 55 years or older with a diagnosis of Parkinson disease who were seen at least twice at the 10 medical centers in the Veterans Affairs Healthcare Network of the South Central region of the United States. Of the 273 male patients diagnosed between October 1, 1997, and September 30, 2009, 62 (22.7%) had a depressive disorder. The overall prevalence of anxiety disorders was 12.8%; patients with comorbid depression had a 5-fold greater prevalence of anxiety disorders than those without depression (35.5% vs 6.2%, Pdepression also had increased prevalence of all physical illnesses examined and more outpatient clinic and mental health visits. Patients with Parkinson disease and comorbid depression are more likely to have anxiety disorders and several physical illnesses, to be using antipsychotic and dementia medicines, and to have increased health service utilization than those without depression.

2015-11-01

The objective of the study was to evaluate whether a motivational-volitional intervention program offered in addition to an existing sport program during stationary treatment is capable of establishing a post-stationary increase in physical activity in persons with mental illness. N=112 in-patients were initially randomly assigned to the control group (CG; standard rehabilitation) or intervention group (IG; standard rehabilitation plus intervention). Assessments were conducted at four measurement points. At 6 months follow up, the level of exercise in the IG was 95 min/week higher than in the CG (p=.02). The participants of the IG were able to increase their level of goal intention until 6 months follow up (t2: p=.03; t4: p=.005); levels of self-efficacy of the IG increased during intervention (t2: p=.001). Changes in volitional aspects were significant over time (t1-t3), but not specifically for the IG. The intervention was effective at increasing the level of physical activity in patients with mental illness who were initially minimally active. Our results suggest that it could be of great use to place the emphasis of a physical activity-enhancing intervention on its motivational effect since volitional aspects are already taken into sufficient account in standard rehabilitation.

A categorization of the publications , according to the issue investigated, the theoretical background used, the research method adopted, the results and conclusions are considered as a starting point in order to present a research profile of the field of study. Next, this profile is discussed and analyzed , pointing out the convergent aspects that characterize the field. Taking this analysis into account, the following thesis (based on Fávero`s proposal, 2000 is defended: in order to generate tools for the teaching practice of Physics through the study of problem solving, a method that substitutes the idea of knowledge transmission in the communication processes that takes place in the classroom should be developed. This method should comprise the idea of interlocution (Vion, 2000 which focuses on social interaction as a means to reveal metacognitive regulations of the subjects, pariticipants in the process, and their development of awareness in relation to a conceptual field (Vergnaud, 1990 – Physics, in this case. The analysis of these processes considers the verbal exchanges among the subjects (Bromberg & Chabrol, 1999 developed in the situation of interaction. This thesis is supported by the articulation of concepts in Psychology, including its interface with linguistics, such as conceptual field, development of awareness and acts of speech, which are reconsidered in this study.

Connolly, Bronwen; O'Neill, Brenda; Salisbury, Lisa; Blackwood, Bronagh

2016-01-01

Background Physical rehabilitation interventions aim to ameliorate the effects of critical illness-associated muscle dysfunction in survivors. We conducted an overview of systematic reviews (SR) evaluating the effect of these interventions across the continuum of recovery. Methods Six electronic databases (Cochrane Library, CENTRAL, DARE, Medline, Embase, and Cinahl) were searched. Two review authors independently screened articles for eligibility and conducted data extraction and quality appraisal. Reporting quality was assessed and the Grading of Recommendations Assessment, Development and Evaluation approach applied to summarise overall quality of evidence. Results Five eligible SR were included in this overview, of which three included meta-analyses. Reporting quality of the reviews was judged as medium to high. Two reviews reported moderate-to-high quality evidence of the beneficial effects of physical therapy commencing during intensive care unit (ICU) admission in improving critical illness polyneuropathy/myopathy, quality of life, mortality and healthcare utilisation. These interventions included early mobilisation, cycle ergometry and electrical muscle stimulation. Two reviews reported very low to low quality evidence of the beneficial effects of electrical muscle stimulation delivered in the ICU for improving muscle strength, muscle structure and critical illness polyneuropathy/myopathy. One review reported that due to a lack of good quality randomised controlled trials and inconsistency in measuring outcomes, there was insufficient evidence to support beneficial effects from physical rehabilitation delivered post-ICU discharge. Conclusions Patients derive short-term benefits from physical rehabilitation delivered during ICU admission. Further robust trials of electrical muscle stimulation in the ICU and rehabilitation delivered following ICU discharge are needed to determine the long-term impact on patient care. This overview provides recommendations for

Physical activity (PA) and exercise is increasingly being recognised as an efficacious component of treatment for various mental disorders. The association between PA and cardiometabolic disease is well established, as is the strong link between mental illness, sedentary behaviour and poor cardiometabolic health. Examples of successful integration of clinical PA programs within mental health treatment facilities are increasing. The aim of this review was to summarise the evidence regarding PA and mental illness, and to present examples of clinical exercise programs within Australian mental health facilities. A narrative synthesis of systematic reviews and clinical trials was conducted. Evidence supporting the inclusion of PA programs as an adjunct to treatment for various conditions was presented; including depression, schizophrenia, anxiety disorders, post-traumatic stress disorder and substance abuse. In light of the available evidence, the inclusion of clinical PA programs within mental health treatment, facilitated by dedicated clinicians (exercise physiologists / physiotherapists) was justified. PA is a feasible, effective and acceptable adjunct to usual care for a variety of mental disorders. There is a clear need for greater investment in initiatives aiming to increase PA among people experiencing mental illness, given the benefits to both mental and physical health outcomes. © The Royal Australian and New Zealand College of Psychiatrists 2015.

Adults with mental illness may have specific attitudes toward physical activity (PA). To assess the PA attitudes of non-institutionalised adults with mental illness, and associations with psychological distress. Participants completed questionnaires on activity preferences (type, context and sources of support), motivators, barriers and attitudes toward personal training (PT). Relationships between responses and distress were assessed using logistic regressions. One-hundred forty-two participants completed the questionnaires. PA context preferences included activities done close to home, outdoors, with professional instruction, with people of the same ability, as part of a healthy lifestyle program and with a social component. The most commonly endorsed source of support was an exercise instructor. Most respondents had never received PT; however, PT had high acceptability. Common barriers included poor physical and mental health, and lack of money. Distress was positively associated with barriers of poor mental health, tiredness, disorganisation, exhaustion and being shy/embarrassed (p ≤ 0.001). Local outdoor walking groups that include social and healthy lifestyle components, and that are led by an exercise instructor who can provide support for overcoming barriers, may best meet PA interests of this group. PT could be an acceptable method for offering individualised support.

1993-09-01

Affective style (AS) and communication deviance (CD) have been suggested as markers of dysfunctional family environments that may be associated with psychiatric illness. Studies have focused mainly on parental responses during family interactions when an offspring is the identified patient. The present study is unique in examining AS and CD in mothers with unipolar depression, bipolar disorder, or chronic physical illness, and in normal controls. The sample consisted of 64 mothers with children ages 8 to 16. Unipolar mothers were more likely to show negative AS than were any other maternal group. There were no group differences for CD. Chronic stress, few positive life events, and single parenting were associated with AS. CD was associated solely with lower socioeconomic status. Results suggest that dysfunctional interactions are determined not only by maternal psychopathology, but also by an array of contextual factors that are related to the quality of the family environment.

The aim of the present study was to document Australian policies on the physical health of people with mental illness and evaluate the capacity of policy to support health needs. A search of state and federal policies on mental and physical illness was conducted, as well as detailed analysis of policy content and the relationships between policies, by applying the World Health Organization Mental Health Action Plan 2013-2020 as an evaluative framework. National policy attention to the physical health of people with mental illness has grown, but there is little interconnection at the national and state levels. State policies across the country are inconsistent, and there is little evidence of consistent policy implementation. A coherent national health policy framework on addressing co-occurring physical and mental illnesses that includes healthcare system reforms and ensuring the interconnectedness of other relevant services should be prioritised.

Bayesian population structure analysis reveals presence of phylogeographically specific sublineages within previously ill-defined T group of Mycobacterium tuberculosis.

Directory of Open Access Journals (Sweden)

Yann Reynaud

Full Text Available Mycobacterium tuberculosis genetic structure, and evolutionary history have been studied for years by several genotyping approaches, but delineation of a few sublineages remains controversial and needs better characterization. This is particularly the case of T group within lineage 4 (L4 which was first described using spoligotyping to pool together a number of strains with ill-defined signatures. Although T strains were not traditionally considered as a real phylogenetic group, they did contain a few phylogenetically meaningful sublineages as shown using SNPs. We therefore decided to investigate if this observation could be corroborated using other robust genetic markers. We consequently made a first assessment of genetic structure using 24-loci MIRU-VNTRs data extracted from the SITVIT2 database (n = 607 clinical isolates collected in Russia, Albania, Turkey, Iraq, Brazil and China. Combining Minimum Spanning Trees and Bayesian population structure analyses (using STRUCTURE and TESS softwares, we distinctly identified eight tentative phylogenetic groups (T1-T8 with a remarkable correlation with geographical origin. We further compared the present structure observed with other L4 sublineages (n = 416 clinical isolates belonging to LAM, Haarlem, X, S sublineages, and showed that 5 out of 8 T groups seemed phylogeographically well-defined as opposed to the remaining 3 groups that partially mixed with other L4 isolates.

The purpose of the study is to document in Hong Kong Chinese cancer survivors cross-sectional associations between illness perceptions, physical symptom distress and dispositional optimism. A consecutive sample of 1036 (response rate, 86.1%, mean age 55.18 years, 60% female) survivors of different cancers recruited within 6 months of completion of adjuvant therapy from Hong Kong public hospitals completed the Brief Illness Perception Questionnaire (B-IPQ), Chinese version of the Memorial Symptom Assessment Scale Short-Form (MSAS-SF), and the revised Chinese version of Life Orientation Test (C-LOT-R), respectively. Stepwise multiple regression analyses examined adjusted associations. IPQ seriousness, symptom identity, illness concern, and emotional impact scores varied by cancer type (p Stress-related, lifestyle, environment, psychological/personality, and health-related factors were most frequently attributed causes of cancer. After adjustment for sample differences, physical symptom distress was significantly associated with all illness perception dimensions (p differences by cancer type were eliminated by adjustment for sample characteristics. Illness perceptions did not differ by cancer type. Greater physical symptom distress and lower levels of optimism were associated with more negative illness perceptions. Understanding how cancer survivors make sense of cancer can clarify an important aspect of adaptation. This in turn can inform interventions to facilitate adjustment. Knowledge contributions include evidence of physical symptom distress correlating with most dimensions of illness perception. Optimism was also associated with cancer survivors' illness perceptions.

In recent years, interactive computer simulations have been progressively integrated in the teaching of the sciences and have contributed significant improvements in the teaching-learning process. Practicing problem-solving is a key factor in science and engineering education. The aim of this study was to design simulation-based problem-solving teaching materials and assess their effectiveness in improving students' ability to solve problems in university-level physics. Firstly, we analyze the effect of using simulation-based materials in the development of students' skills in employing procedures that are typically used in the scientific method of problem-solving. We found that a significant percentage of the experimental students used expert-type scientific procedures such as qualitative analysis of the problem, making hypotheses, and analysis of results. At the end of the course, only a minority of the students persisted with habits based solely on mathematical equations. Secondly, we compare the effectiveness in terms of problem-solving of the experimental group students with the students who are taught conventionally. We found that the implementation of the problem-solving strategy improved experimental students' results regarding obtaining a correct solution from the academic point of view, in standard textbook problems. Thirdly, we explore students' satisfaction with simulation-based problem-solving teaching materials and we found that the majority appear to be satisfied with the methodology proposed and took on a favorable attitude to learning problem-solving. The research was carried out among first-year Engineering Degree students.

We have studied the impacts of web-based Computer Coaches on educational outputs and outcomes. This presentation will describe the technical and conceptual framework related to the Coaches and discuss undergraduate students' favorability of the Coaches. Moreover, its impacts on students' physics problem solving performance and on their conceptual understanding of physics will be reported. We used a qualitative research technique to collect and analyze interview data from 19 undergraduate students who used the Coaches in the interview setting. The empirical results show that the favorability and efficacy of the Computer Coaches differ considerably across students of different educational backgrounds, preparation levels, attitudes and epistemologies about physics learning. The interview data shows that female students tend to have more favorability supporting the use of the Coach. Likewise, our assessment suggests that female students seem to benefit more from the Coaches in their problem solving performance and in conceptual learning of physics. Finally, the analysis finds evidence that the Coach has potential for increasing efficiency in usage and for improving students' educational outputs and outcomes under its customized usage.

To study the effectiveness of Exergames in communal psychiatry for persons with severe mental illness, a randomized cluster study was performed. The hypothesis was to increase physical activity habits to improve somatic health. To identify factors promoting or impeding the use of the Exergames. Assessments of BMI, blood pressure, physical fitness, SF36, GAF and social interactions were studied at baseline and 10 months. An integrated methods design using content analysis of focus group interviews was integrated with a statistical analysis. Forty-three persons were randomized to the intervention and 30 to the control group. The qualitative interviews included 18 users, 11 staffs and one technical assistant. There were no significant between-group changes in physical activity behaviours or somatic health parameters after 10 months. Only 5% of the intervention group made systematic use of the intervention. Technological difficulties and staff attitudes were found to be barriers. The Exergames were perceived as technically complicated. The staff did not see playing TV games as important and negative attitudes were found. Exergames was not a successful intervention to increase physical activity behaviours in persons with severe mental illness in the community. Exergames and motivation for physical activity in this group is problematic. Implications for rehabilitation There are difficulties to change passive physical activity habits for persons with severe mental illness, living in sheltered housing conditions in the community due to negative symptoms with depression, low motivation and bad self -confidence. An exergame intervention was not successful in this group of persons. No somatic health benefits were found. Simple physical activities and offering different choices meeting different user needs should be offered. Ensuring user and staff engagement, good technical knowledge and good monitoring is a need for a successful intervention, if Exergames are offered as an

Patients admitted to the intensive care unit with critical illness often experience significant physical impairments, which typically persist for many years following resolution of the original illness. Physical rehabilitation interventions that enhance restoration of physical function have been evaluated across the continuum of recovery following critical illness including within the intensive care unit, following discharge to the ward and beyond hospital discharge. Multiple systematic reviews have been published appraising the expanding evidence investigating these physical rehabilitation interventions, although there appears to be variability in review methodology and quality. We aim to conduct an overview of existing systematic reviews of physical rehabilitation interventions for adult intensive care patients across the continuum of recovery. This protocol has been developed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol (PRISMA-P) guidelines. We will search the Cochrane Systematic Review Database, Database of Abstracts of Reviews of Effectiveness, Cochrane Central Register of Controlled Trials, MEDLINE, Excerpta Medica Database and Cumulative Index to Nursing and Allied Health Literature databases. We will include systematic reviews of randomised controlled trials of adult patients, admitted to the intensive care unit and who have received physical rehabilitation interventions at any time point during their recovery. Data extraction will include systematic review aims and rationale, study types, populations, interventions, comparators, outcomes and quality appraisal method. Primary outcomes of interest will focus on findings reflecting recovery of physical function. Quality of reporting and methodological quality will be appraised using the PRISMA checklist and the Assessment of Multiple Systematic Reviews tool. We anticipate the findings from this novel overview of systematic reviews will contribute to the

In the presence of quantum-gravity fluctuations (space-time foam), the CPT operator may be ill-defined. Its perturbative treatment leads to a modification of the Einstein-Podolsky-Rosen correlation of the neutral meson system by adding an entanglement-weakening term of the wrong exchange symmetry, the ω-effect. In the current paper we identify how to probe the complex ω in the entangled B{sub d}-system using the flavour (f)-CP(g) eigenstate decay channels: the connection between the intensities for the two time-ordered decays (f, g) and (g, f) is lost. Appropriate observables are constructed allowing independent experimental determinations of Re(ω) and Im(ω), disentangled from CPT violation in the evolution Hamiltonian Re(θ) and Im(θ). 2σ tensions for both Re(θ) and Im(ω) are shown to be uncorrelated.

2010-04-01

The impact of the experience and diagnosis of mental illness on one's identity has long been recognized; however, little is known about the impact of illness identity, which we define as the set of roles and attitudes that a person has developed in relation to his or her understanding of having a mental illness. The present article proposes a theoretically driven model of the impact of illness identity on the course and recovery from severe mental illness and reviews relevant research. We propose that accepting a definition of oneself as mentally ill and assuming that mental illness means incompetence and inadequacy impact hope and self-esteem, which further impact suicide risk, coping, social interaction, vocational functioning, and symptom severity. Evidence supports most of the predictions made by the model. Implications for psychiatric rehabilitation services are discussed.

Increasing physical activity in patients with severe mental illness is believed to have positive effects on physical health, psychiatric symptoms and as well quality of life. Till now, little is known about the relationship between physical activity and quality of life in long-term hospitalized patients with severe mental illness and knowledge of the determinants of behavioural change is lacking. The purpose of this study was to elucidate the relationship between objectively measured physical activity and quality of life, and explore modifiable psychological determinants of change in physical activity in long-term hospitalized patients with severe mental illness. In 184 inpatients, physical activity was measured using an accelerometer (ActiGraph GTX+). Quality of life was assessed by EuroQol-5D and WHOQol-Bref. Attitude and perceived self-efficacy towards physical activity were collected using the Physical Activity Enjoyment Scale and the Multidimensional Self Efficacy Questionnaire, respectively. Patient and disease characteristics were derived retrospectively from electronic patient records. Associations and potential predictors were analysed using hierarchical regression. Physical activity was positively related with and a predictor of all quality of life outcomes except on the environmental domain, independent of patient and disease characteristics. However, non-linear relationships showed that most improvement in quality of life lies in the change from sedentary to light activity. Attitude and self-efficacy were not related to physical activity. Physical activity is positively associated with quality of life, especially for patients in the lower spectrum of physical activity. An association between attitude and self-efficacy and physical activity was absent. Therefore, results suggest the need of alternative, more integrated and (peer-)supported interventions to structurally improve physical activity in this inpatient population.

Full Text Available The National Curriculum Statement for matric physical science places strong emphasis on the development of critical thinking and reasoning abilities of pupils. The successful implementation of this curriculum therefore requires teachers who are competent in the cognitive (intellectual skills and strategies needed for learning science effectively. Testing of teachers’ competence in this aspect is therefore important. I therefore analysed teachers’ answers to questions that were carefully designed to test competence in some basic intellectual strategies that are important for problem solving in physical science courses. A total of 73 matric physical science teachers, from about 50 Dinaledi schools in the North West and KwaZulu-Natal provinces in South Africa, were tested in five intellectual strategies: clear representation of problems, identifying and focusing on the goal, identification and use of relevant principles, use of equations for deductions and proceeding step-by-step with the solution. The teachers’ competence was poor in all the intellectual strategies tested. About 60% (the average performance in all 13 questions used for testing of teachers tested were unable to solve the questions correctly. An important objective of the curriculum is the development of critical thinking, scientific reasoning and strategies of pupils. This study shows that the achievement of this objective will be seriously handicapped because of the lack of competence of many teachers in intellectual strategies. There is therefore a need to train teachers in order to increase their competence in this aspect.

Excess mortality among people with severe mental illness (SMI) is largely attributed to co-morbid physical illness. Improving the physical health of this population is critically important; however, physical health monitoring among people with SMI is often inadequate. This study aimed to facilitate an enhanced understanding of barriers to successfully attend to clients' physical health in mental health settings, through exploring care coordinators' views and experiences regarding their ability to monitor physical health in clients with SMI (specifically, psychosis). Semi-structured interviews were conducted with seven care coordinators from a South East London (UK) community mental health team. Data were analysed using thematic analysis principles. Three themes were identified in these data, capturing (1) how care coordinators viewed the professional roles of other clinical staff and themselves, (2) views on barriers to the provision of physical healthcare and (3) factors that motivated care coordinators to attend to clients' physical health. Our findings can inform efforts to implement physical healthcare interventions within mental health settings. Such insights are timely, as academic literature and guidelines regarding clinical practice increasingly promote the value of integrated provision of mental and physical healthcare.

Although road bicycle races have been held for more than a century, injury and illness patterns during multi-day bicycle events have not been widely studied. The aim of this study was to determine the incidence of injury and illness among riders and describe the medical care interventions provided to participants of cycling road races. A prospective observational study was conducted on the Presidential Cycling Tour of Turkey, which was held between April 26 and May 3, 2015. The race lasted 8 days and covered 1258 km of road. There were 166 elite cycling athletes representing 21 teams from various countries. Data collected pertaining to incidents involving injury or illness included the following: type of injury; anatomical location of injury; details of the medical encounter; location of the intervention; treatment provided; medication administered and disposition of the rider. An injury was defined as a physical complaint or observable damage to the body produced by the transfer of energy of the rider. An illness was defined as a physical complaint or presentation not related to injury. The overall incidence (injury and illness) was 5.83 per 1000 cycling hours. (Injury incidence was 2.82 vs illness incidence of 3.01 per 1000 hours cycling). A total of 31 incidents occurred. Of these, 15 were injuries, while 16 were complaints of a non-traumatic nature. A total of 43 interventions were made in the 15 cases of injury. The most commonly injured body regions were limbs; the majority of injuries involved the skin and soft tissue. The most common medical intervention was wound care (64% of all interventions). Two riders had to withdraw from the race, and one was hospitalized due to a traumatic pneumothorax. None of the non-traumatic cases resulted in withdrawal from the race. A broad spectrum of illness and injury occurs during elite multi-day road races, ranging from simple skin injuries to serious injuries requiring hospital admission. Most injuries and illnesses are

One finding of cognitive research is that people do not automatically acquire usable knowledge by spending lots of time on task. Because students' knowledge hierarchy is more fragmented, "knowledge chunks" are smaller than those of experts. The limited capacity of short term memory makes the cognitive load high during problem solving tasks, leaving few cognitive resources available for meta-cognition. The abstract nature of the laws of physics and the chain of reasoning required to draw meaningful inferences makes these issues critical. In order to help students, it is crucial to consider the difficulty of a problem from the perspective of students. We are developing and evaluating interactive problem-solving tutorials to help students in the introductory physics courses learn effective problem-solving strategies while solidifying physics concepts. The self-paced tutorials can provide guidance and support for a variety of problem solving techniques, and opportunity for knowledge and skill acquisition.

Full Text Available Abstract Introduction This review of 25 consecutive patients with Morgellons disease (MD was undertaken for two primary and extremely fundamental reasons. For semantic accuracy, there is only one "proven" MD patient: the child first given that label. The remainder of inclusive individuals adopted the label based on related descriptions from 1544 through 1884, an internet description quoted from Sir Thomas Browne (1674, or was given the label by practitioners using similar sources. Until now, there has been no formal characterization of MD from detailed examination of all body systems. Our second purpose was to differentiate MD from Delusions of Parasitosis (DP, another "informal" label that fit most of our MD patients. How we defined and how we treated these patients depended literally on factual data that would determine outcome. How they were labeled in one sense was irrelevant, except for the confusing conflict rampant in the medical community, possibly significantly skewing treatment outcomes. Case presentation Clinical information was collected from 25 of 30 consecutive self-defined patients with Morgellons disease consisting of laboratory data, medical history and physical examination findings. Abnormalities were quantified and grouped by system, then compared and summarized, but the numbers were too small for more complex mathematical analysis. The quantification of physical and laboratory abnormalities allowed at least the creation of a practical clinical boundary, separating probable Morgellons from non-Morgellons patients.

Modifications of Steepest Descent Method and Conjugate Gradient Method Against Noise for Ill-posed Linear Systems

Directory of Open Access Journals (Sweden)

Chein-Shan Liu

2012-04-01

Full Text Available It is well known that the numerical algorithms of the steepest descent method (SDM, and the conjugate gradient method (CGM are effective for solving well-posed linear systems. However, they are vulnerable to noisy disturbance for solving ill-posed linear systems. We propose the modifications of SDM and CGM, namely the modified steepest descent method (MSDM, and the modified conjugate gradient method (MCGM. The starting point is an invariant manifold defined in terms of a minimum functional and a fictitious time-like variable; however, in the final stage we can derive a purely iterative algorithm including an acceleration parameter. Through the Hopf bifurcation, this parameter indeed plays a major role to switch the situation of slow convergence to a new situation that the functional is stepwisely decreased very fast. Several numerical examples are examined and compared with exact solutions, revealing that the new algorithms of MSDM and MCGM have good computational efficiency and accuracy, even for the highly ill-conditioned linear equations system with a large noise being imposed on the given data.

Mannarini, Stefania; Boffo, Marilisa

2014-01-01

The present study aimed at the definition of a latent measurement dimension underlying an implicit measure of automatic associations between the concept of mental illness and the psychosocial and biogenetic causal explanatory attributes. To this end, an Implicit Association Test (IAT) assessing the association between the Mental Illness and Physical Illness target categories to the Psychological and Biologic attribute categories, representative of the causal explanation domains, was developed. The IAT presented 22 stimuli (words and pictures) to be categorized into the four categories. After 360 university students completed the IAT, a Many-Facet Rasch Measurement (MFRM) modelling approach was applied. The model specified a person latency parameter and a stimulus latency parameter. Two additional parameters were introduced to denote the order of presentation of the task associative conditions and the general response accuracy. Beyond the overall definition of the latent measurement dimension, the MFRM was also applied to disentangle the effect of the task block order and the general response accuracy on the stimuli response latency. Further, the MFRM allowed detecting any differential functioning of each stimulus in relation to both block ordering and accuracy. The results evidenced: a) the existence of a latency measurement dimension underlying the Mental Illness versus Physical Illness - Implicit Association Test; b) significant effects of block order and accuracy on the overall latency; c) a differential functioning of specific stimuli. The results of the present study can contribute to a better understanding of the functioning of an implicit measure of semantic associations with mental illness and give a first blueprint for the examination of relevant issues in the development of an IAT.

The lifespan of people with severe mental illness (SMI) is shorter compared to the general population. This excess mortality is mainly due to physical illness. We report prevalence rates of different physical illnesses as well as important individual lifestyle choices, side effects of psychotropic treatment and disparities in health care access, utilization and provision that contribute to these poor physical health outcomes. We searched MEDLINE (1966 – August 2010) combining the MeSH terms of schizophrenia, bipolar disorder and major depressive disorder with the different MeSH terms of general physical disease categories to select pertinent reviews and additional relevant studies through cross-referencing to identify prevalence figures and factors contributing to the excess morbidity and mortality rates. Nutritional and metabolic diseases, cardiovascular diseases, viral diseases, respiratory tract diseases, musculoskeletal diseases, sexual dysfunction, pregnancy complications, stomatognathic diseases, and possibly obesity-related cancers are, compared to the general population, more prevalent among people with SMI. It seems that lifestyle as well as treatment specific factors account for much of the increased risk for most of these physical diseases. Moreover, there is sufficient evidence that people with SMI are less likely to receive standard levels of care for most of these diseases. Lifestyle factors, relatively easy to measure, are barely considered for screening; baseline testing of numerous important physical parameters is insufficiently performed. Besides modifiable lifestyle factors and side effects of psychotropic medications, access to and quality of health care remains to be improved for individuals with SMI. PMID:21379357

Solving Some Special Cases of Monomial Ratio Equations Appearing Frequently in Physical and Engineering Problems

Directory of Open Access Journals (Sweden)

Enrique Castillo

2016-01-01

Full Text Available We first show that monomial ratio equations are not only very common in Physics and Engineering, but the natural type of equations in many practical problems. More precisely, in the case of models involving scale variables if the used formulas are not of this type they are not physically valid. The consequence is that when estimating the model parameters we are faced with systems of monomial ratio equations that are nonlinear and difficult to solve. In this paper, we provide an original algorithm to obtain the unique solutions of systems of equations made of linear combinations of monomial ratios whose coefficient matrix has a proper null space with low dimension that permits solving the problem in a simple way. Finally, we illustrate the proposed methods by their application to two practical problems from the hydraulic and structural fields.

Critically ill patients frequently experience severe agitation placing them at risk of harm. Physical restraint is common in intensive care units (ICUs) for clinician concerns about safety. However, physical restraint may not prevent medical device removal and has been associated with negative physical and psychological consequences. While professional society guidelines, legislation, and accreditation standards recommend physical restraint minimization, guidelines for critically ill patients are over a decade old, with recommendations that are non-specific. Our systematic review will synthesize evidence on physical restraint in critically ill adults with the primary objective of identifying effective minimization strategies. Two authors will independently search from inception to July 2016 the following: Ovid MEDLINE, CINAHL, Embase, Web of Science, Cochrane Library, PROSPERO, Joanna Briggs Institute, grey literature, professional society websites, and the International Clinical Trials Registry Platform. We will include quantitative and qualitative study designs, clinical practice guidelines, policy documents, and professional society recommendations relevant to physical restraint of critically ill adults. Authors will independently perform data extraction in duplicate and complete risk of bias and quality assessment using recommended tools. We will assess evidence quality for quantitative studies using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach and for qualitative studies using the Confidence in the Evidence from Reviews of Qualitative Research (CERQual) guidelines. Outcomes of interest include (1) efficacy/effectiveness of physical restraint minimization strategies; (2) adverse events (unintentional device removal, psychological impact, physical injury) and associated benefits including harm prevention; (3) ICU outcomes (ventilation duration, length of stay, and mortality); (4) prevalence, incidence, patterns of use

Methods Two authors will independently search from inception to July 2016 the following: Ovid MEDLINE, CINAHL, Embase, Web of Science, Cochrane Library, PROSPERO, Joanna Briggs Institute, grey literature, professional society websites, and the International Clinical Trials Registry Platform. We will include quantitative and qualitative study designs, clinical practice guidelines, policy documents, and professional society recommendations relevant to physical restraint of critically ill adults. Authors will independently perform data extraction in duplicate and complete risk of bias and quality assessment using recommended tools. We will assess evidence quality for quantitative studies using the Grading of Recommendations Assessment, Development and Evaluation (GRADE approach and for qualitative studies using the Confidence in the Evidence from Reviews of Qualitative Research (CERQual guidelines. Outcomes of interest include (1 efficacy/effectiveness of physical restraint minimization strategies; (2 adverse events (unintentional device removal, psychological impact, physical injury and associated benefits including harm prevention; (3 ICU outcomes (ventilation duration, length of stay, and mortality; (4

Effects of representation on students solving physics problems: A fine-grained characterization

Full Text Available Recent papers document that student problem-solving competence varies (often strongly with representational format, and that there are significant differences between the effects that traditional and reform-based instructional environments have on these competences [Kohl and Finkelstein, Phys. Rev. ST Phys. Educ. Res. 1, 010104 (2005; Kohl and Finkelstein, Phys. Rev. ST Phys. Educ. Res. 2, 010102 (2006]. These studies focused on large-lecture introductory physics courses, and included aggregate data on student performance on quizzes and homeworks. In this paper, we complement previous papers with finer-grained in-depth problem-solving interviews. In 16 interviews of students drawn from these classes, we investigate in more detail how and when student problem-solving performance varies with problem representation (verbal, mathematical, graphical, or pictorial. We find that student strategy often varies with representation, and that in this environment students who show more strategy variation tend to perform more poorly. We also verify that student performance depends sensitively on the particular combination of representation, topic, and student prior knowledge. Finally, we confirm that students have generally robust opinions of their representational skills, and that these opinions correlate poorly with their actual performances.

Bear, Danielle E; Wandrag, Liesl; Merriweather, Judith L; Connolly, Bronwen; Hart, Nicholas; Grocott, Michael P W

2017-08-26

The lack of benefit from randomised controlled trials has resulted in significant controversy regarding the role of nutrition during critical illness in terms of long-term recovery and outcome. Although methodological caveats with a failure to adequately appreciate biological mechanisms may explain these disappointing results, it must be acknowledged that nutritional support during early critical illness, when considered alone, may have limited long-term functional impact.This narrative review focuses specifically on recent clinical trials and evaluates the impact of nutrition during critical illness on long-term physical and functional recovery.Specific focus on the trial design and methodological limitations has been considered in detail. Limitations include delivery of caloric and protein targets, patient heterogeneity, short duration of intervention, inappropriate clinical outcomes and a disregard for baseline nutritional status and nutritional intake in the post-ICU period.With survivorship at the forefront of critical care research, it is imperative that nutrition studies carefully consider biological mechanisms and trial design because these factors can strongly influence outcomes, in particular long-term physical and functional outcome. Failure to do so may lead to inconclusive clinical trials and consequent rejection of the potentially beneficial effects of nutrition interventions during critical illness.

Although guilt is a widely accepted feature of depression, there is limited and inconsistent data defining the nature of this symptom. The purpose of the current study was to examine the specificity and nature of guilt in subjects with major depression as compared to patients with another chronic medical illness and healthy controls. Outpatients with current major depressive episode (MDE; n=34), past-MDE (n=22), chronic cardiac illness (n=20) and healthy controls (n=59) were administered the following measures: The Guilt Inventory (GI), State Shame and Guilt Scale (SSGS), 17-item Hamilton Rating Scale for Depression (Ham-D) and the Structured Clinical Interview for DSM-IV. Overall multivariate analysis of covariance comparing mean scores for the six guilt subscales [state-guilt, trait-guilt, moral standards (from the GI); state-guilt, -pride, and -shame (from the SSGS)] across the four groups was significant (F=9.1, df=6:121, pguilt (GI), current-MDE>past-MDE>cardiac=healthy controls; for trait-guilt (GI), current-MDE=past-MDE>cardiac=healthy controls; for state-shame, -guilt and -pride (SSGS), current-MDE>past-MDE, past-MDE=cardiac, past-MDE>healthy, cardiac=healthy controls. Among depressed patients, there was significant correlation between Ham-D score and all guilt sub-scales (pguilt, shame and low pride distinguish acutely depressed from all other groups, and are highly influenced by severity of depression. Trait-guilt does not differentiate acute from past depressed. Data suggests guilt may represent both an enduring and fluctuating feature of depressive illness over its longitudinal course.

Physics of Intrinsic and Extrinsic Factors that Cause the Onset of the Deadliest Illness of Mankind and are Important for Diagnostics and Treatment

Science.gov (United States)

Saxena, Arjun

One of the most important topic of research in the field of Physics of Behavior is the deadliest illness of mankind which is the group of illnesses called mental illnesses. They are getting attention increasingly worldwide by the medical communities and their respective governments, because of the following fact. It is now well established that these illnesses cause more loss of human lives, destruction of families, businesses and overall economy than all the other illnesses combined. The purpose of this paper is to identify and provide solutions to two fundamental issues of such illnesses which still remain as problems. One is the stigma associated with them because of their name ``mental''. The patients are regarded as less than normal because their illness is only ``mental'' in origin. The second is that it is still not widely recognized that they are caused by medical problems in their ``brain'' which afflict their ``mind''. This paper explains this and gives an improved 3-D model using the physics of intrinsic and extrinsic factors of both ``brain'' and ``mind''. It leads to an important new name, ``BAMI'' (Brain and Mind Illness), which eliminates the stigma and gives quantitative parameters to diagnose the illness and monitor medicines to treat such illnesses.

'A tale of two cases:' the health, illness, and physical activity stories of two children living with cystic fibrosis.

Storytelling is perennial, and central to the human condition. Although illness may shatter identity and one's role and place in the broader social world, narrative may aid in the process of self-reparation. Despite the merits of the narrative approach, it has been underutilized with children who are living with cystic fibrosis (CF). The role that illness narratives may play in influencing CF youths' physical activity also remains poorly investigated. This article drew on the qualitative case study methodological tradition to narrate the stories of two children living with CF at a children's hospital in Canada. The findings beg researchers to consider (a) how children with life-limiting diseases borrow multiple illness narrative types, (b) the role of development in influencing the kinds of stories that children can tell, and (c) the impact of illness narratives on physical activity. By rendering the tales of two CF youth in this study, we respond to Aurthur Frank's call; taking a multiple narrative turn, we listen to stories of a different kind of suffering.

To determine the effectiveness of Problem-Solving Therapy (PST) in older hemodialysis (HD) patients by assessing changes in health-related quality of life and problem-solving skills. 33 HD patients in an outpatient hemodialysis center without active medical and psychiatric illness were enrolled. The intervention group (n = 15) received PST from a licensed social worker for 6 weeks, whereas the control group (n = 18) received usual care treatment. In comparison to the control group, patients receiving PST intervention reported improved perceptions of mental health, were more likely to view their problems with a positive orientation and were more likely to use functional problem-solving methods. Furthermore, this group was also more likely to view their overall health, activity limits, social activities and ability to accomplish desired tasks with a more positive mindset. The results demonstrate that PST may positively impact mental health components of quality of life and problem-solving coping among older HD patients. PST is an effective, efficient, and easy to implement intervention that can benefit problem-solving abilities and mental health-related quality of life in older HD patients. In turn, this will help patients manage their daily living activities related to their medical condition and reduce daily stressors.

Physics of Fission and Fusion for the Diagnostics and Monitoring of the Deadliest Illness of Mankind

Science.gov (United States)

Saxena, Arjun

2015-03-01

The physics of fission and fusion has been well known for the past several decades. It has been used primarily for destructive purposes (e. g., nuclear armaments) with both processes. However for peaceful purposes, e. g., generation of energy, only fission has been used, but not yet fusion. It is also well known that the deadliest illness of mankind is the group of illnesses called mental illnesses. A large segment of the world population is afflicted by them causing more loss of human lives, destruction of families, businesses and overall economy than all the other illnesses combined. Despite outstanding advancements in medical research and huge investments, unfortunately no diagnostic techniques have yet been found which can characterize the patient's mental illness. Consequently, no quantitative monitoring techniques are available to evaluate the efficacy of the various medicines used to treat the patients, and to develop them in the pharmaceutical labs. The purpose of this paper is to apply the constructive aspects of fission and fusion to identify the missing links in the diagnosis and treatment of mental illnesses. Each patient is a unique human being, not a disease or a group of symptoms. This makes it even more difficult to treat the patients suffering from mental illnes

To evaluate the relationship between quality of life (QOL) and physical as well as psychological variables in Chinese breast cancer patients. This multicenter cross-sectional study enrolled 254 Chinese breast cancer patients in different stages and treatment phases. They answered standard instruments assessing QOL (EORTC), somatic symptom severity (PHQ-15), depression (PHQ-9), anxiety (GAD-7), health-related anxiety (WI-7), illness perception (BIPQ), and sense of coherence (SOC-9). Canonical correlation was applied to identify the strongest correlates between the physical, emotional and social QOL scales and the physical and psychological variables. In our sample, a low global QOL was significantly associated with the following physical and psychological variables: symptom-related disability (Karnofsky Index) (r = .211, p illness perception (r = -.411, p illness perception, and low sense of coherence showed the strongest correlations with low physical, emotional and social functioning. The first three significant canonical correlations between these two sets of variables were .78, .56, and .45. QOL in Chinese breast cancer patients is strongly associated with psychological factors. Our results suggest that Chinese physicians and nurses should incorporate these factors into their care for women with breast cancer to improve patients' QOL.

Based on the psychoanalytic reading of Homer’s Iliad whose principal theme is “Achilles’ rage” (the semi-mortal hero invulnerable in all of his body except for his heel, hence “Achilles’ heel” has come to mean a person’s principal weakness), we aimed to assess whether “narcissistic rage” has an impact on several psychosocial variables in patients with severe physical illness across time. In 878 patients with cancer, rheumatological diseases, multiple sclerosis, inflammatory bowel disease, and glaucoma, we assessed psychological distress (SCL-90 and GHQ-28), quality of life (WHOQOL-BREF), interpersonal difficulties (IIP-40), hostility (HDHQ), and defense styles (DSQ). Narcissistic rage comprised DSQ “omnipotence” and HDHQ “extraverted hostility”. Hierarchical multiple regressions analyses were performed. We showed that, in patients with disease duration less than one year, narcissistic rage had a minor impact on psychosocial variables studied, indicating that the rage was rather part of a “normal” mourning process. On the contrary, in patients with longer disease duration, increased rates of narcissistic rage had a great impact on all outcome variables, and the opposite was true for patients with low rates of narcissistic rage, indicating that narcissistic rage constitutes actually an “Achilles’ Heel” for patients with long-term physical illness. These findings may have important clinical implications. PMID:19936167

Applied Physics Education: PER focused on Physics-Intensive Careers

2017-01-01

Physics education research is moving beyond classroom learning to study the application of physics education within STEM jobs and PhD-level research. Workforce-related PER is vital to supporting physics departments as they educate students for a diverse range of careers. Results from an on-going study involving interviews with entry-level employees, academic researchers, and supervisors in STEM jobs describe the ways that mathematics, physics, and communication are needed for workplace success. Math and physics are often used for solving ill-structured problems that involve data analysis, computational modeling, or hands-on work. Communication and collaboration are utilized in leadership, sales, and as way to transfer information capital throughout the organization through documentation, emails, memos, and face-to-face discussions. While managers and advisors think a physics degree typically establishes technical competency, communication skills are vetted through interviews and developed on the job. Significant learning continues after graduation, showing the importance of cultivating self-directed learning habits and the critical role of employers as educators of specialized technical abilities through on-the-job training.

Full Text Available Drawing appropriate diagrams is a useful problem solving heuristic that can transform a problem into a representation that is easier to exploit for solving it. One major focus while helping introductory physics students learn effective problem solving is to help them understand that drawing diagrams can facilitate problem solution. We conducted an investigation in which two different interventions were implemented during recitation quizzes in a large enrollment algebra-based introductory physics course. Students were either (i asked to solve problems in which the diagrams were drawn for them or (ii explicitly told to draw a diagram. A comparison group was not given any instruction regarding diagrams. We developed rubrics to score the problem solving performance of students in different intervention groups and investigated ten problems. We found that students who were provided diagrams never performed better and actually performed worse than the other students on three problems, one involving standing sound waves in a tube (discussed elsewhere and two problems in electricity which we focus on here. These two problems were the only problems in electricity that involved considerations of initial and final conditions, which may partly account for why students provided with diagrams performed significantly worse than students who were not provided with diagrams. In order to explore potential reasons for this finding, we conducted interviews with students and found that some students provided with diagrams may have spent less time on the conceptual analysis and planning stage of the problem solving process. In particular, those provided with the diagram were more likely to jump into the implementation stage of problem solving early without fully analyzing and understanding the problem, which can increase the likelihood of mistakes in solutions.

Full Text Available Background: Comorbid chronic illnesses, such as cardiovascular disease, respiratory conditions, and type 2 diabetes are common among people with serious mental illness. Management of comorbid illness in the mental health setting is sometimes ad hoc and poorly delivered. Use of a cardiometabolic health nurse (CHN is proposed as one strategy to improve the delivery of physical health care to this vulnerable population. Objective: To report the CHN’s utilization of primary care and allied health referrals from a trial carried out in a regional community mental health service. Design: Feasibility study. Mental health consumers were referred by their case manager or mental health nurse to the CHN. The CHN coordinated the physical health care of community-based mental health consumers by identifying the need for, and providing referrals to, additional services, including primary care, allied health, and community-based services. Results: Sixty-two percent of participants referred to the CHN received referrals for primary care, allied health, and community-based services. Almost all referrals received follow-up by the CHN. Referrals were most commonly directed to a general practitioner and for nurse-delivered services. Conclusion: The CHN role shows promise in coordinating the physical health of community-based mental health consumers. More studies on role integration and development of specific outcome measurement tools are needed.

Patients with severe mental illness (SMI) treated with antipsychotic medication are at increased risk of metabolic side-effects like weight gain, diabetes mellitus and dyslipidaemia. This study aims to examine the feasibility of maintaining a physical health monitoring sheet in patients' records and its impact on physical health of patients with SMI, over a period of one year. A physical health monitoring sheet was introduced in all the patients' records on a 15-bedded male medium secure forensic psychiatric rehabilitation unit, as a prompt to regularly monitor physical health parameters. An audit cycle was completed over a one year period. The data between baseline and re-audit were compared. At baseline, 80 per cent of the patients were identified as smokers, 80 per cent had increased body mass index (BMI) and 87 per cent had raised cardiovascular risk over the next ten years. Appropriate interventions were offered to address the risks. At re-audit, the physical health monitoring sheets were up to date in 100 per cent of patients' records. The serum lipids and cardiovascular risk over the next ten years reduced over time. No significant change was noted on the parameters including BMI, central obesity, high blood pressure and smoking status. This was a pilot study and was limited by the small sample size, male gender only and the specific nature of the ward. There is a need for improved access to physical health care in long-stay psychiatric settings. A more robust lifestyle modification programme is required to positively influence the physical health parameters in this cohort of patients. Introduction of a physical health monitoring sheet in patients' records led to regular screening of cardiovascular risks and subsequent increased prescribing of hypolipidaemic agents in individuals with severe mental illness.

This study examined whether the social cognitive theory (SCT) model can be used to explain the variance in physical exercise among persons with serious mental illnesses. A cross-sectional, correlational design was employed. Participants from community mental health centers and supported housing programs (N = 120) completed 9 measures on exercise, social support, self-efficacy, outcome expectations, barriers, and goal-setting. Hierarchical regression tested the relationship between self-report physical activity and SCT determinants while controlling for personal characteristics. The model explained 25% of the variance in exercise. Personal characteristics explained 18% of the variance in physical activity, SCT variables of social support, self-efficacy, outcome expectations, barriers, and goals were entered simultaneously, and they added an r2 change value of .07. Gender (β = -.316, p = .001) and Brief Symptom Inventory Depression subscale (β = -2.08, p exercise. In a separate stepwise multiple regression, we entered only SCT variables as potential predictors of exercise. Goal-setting was the single significant predictor, F(1, 118) = 13.59, p exercise in persons with mental illnesses. Goal-setting practices, self-efficacy, outcome expectations and social support from friends for exercise should be encouraged by psychiatric rehabilitation practitioners. People with more depressive symptoms and women exercise less. More work is needed on theoretical exploration of predictors of exercise. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Iterative Tensor Voting for Perceptual Grouping of Ill-Defined Curvilinear Structures: Application to Adherens Junctions

Science.gov (United States)

Loss, Leandro A.; Bebis, George; Parvin, Bahram

2012-01-01

In this paper, a novel approach is proposed for perceptual grouping and localization of ill-defined curvilinear structures. Our approach builds upon the tensor voting and the iterative voting frameworks. Its efficacy lies on iterative refinements of curvilinear structures by gradually shifting from an exploratory to an exploitative mode. Such a mode shifting is achieved by reducing the aperture of the tensor voting fields, which is shown to improve curve grouping and inference by enhancing the concentration of the votes over promising, salient structures. The proposed technique is applied to delineation of adherens junctions imaged through fluorescence microscopy. This class of membrane-bound macromolecules maintains tissue structural integrity and cell-cell interactions. Visually, it exhibits fibrous patterns that may be diffused, punctate and frequently perceptual. Besides the application to real data, the proposed method is compared to prior methods on synthetic and annotated real data, showing high precision rates. PMID:21421432

Self-complexity as a cognitive buffer against stress-related illness and depression.

Science.gov (United States)

Linville, P W

1987-04-01

This prospective study tested the self-complexity buffering hypothesis that greater self-complexity moderates the adverse impact of stress on depression and illness. This hypothesis follows from a model that assumes self-knowledge is represented in terms of multiple self-aspects. As defined in this model, greater self-complexity involves representing the self in terms of a greater number of cognitive self-aspects and maintaining greater distinctions among self-aspects. Subjects completed measures of stressful events, self-complexity, depression, and illness in two sessions separated by 2 weeks. A multiple regression analysis used depression and illness at Time 2 as outcomes, stressful life events and self-complexity at Time 1 as predictors, and depression and illness at Time 1 as control variables. The Stress X Self-Complexity interaction provided strong support for the buffering hypothesis. Subjects higher in self-complexity were less prone to depression, perceived stress, physical symptoms, and occurrence of the flu and other illnesses following high levels of stressful events. These results suggest that vulnerability to stress-related depression and illness is due, in part, to differences in cognitive representations of the self.

Full Text Available We assessed adherence to and predictors of two components of a telephone-supported self-care intervention for depression among primary care adults aged 40 and above with chronic physical illnesses and comorbid depressive symptoms. Participants received a “toolkit” containing six self-care tools. Trained lay self-care “coaches” negotiated a contact schedule of up to weekly contacts. Study outcomes were levels of completion of the self-care tool and the coach contacts at the 2-month follow-up. Coaches reported the number of completed contacts. In all, 57 of 63 participants completed the 2-month follow-up. Of these, 67% completed at least 1 tool; the mean number of coach contacts was 5.7 (SD = 2.4 of a possible 9 contacts (63% adherence. Higher disease comorbidity and lower initial depression severity independently predicted better tool adherence. Findings suggest that people with chronic physical illnesses can achieve acceptable levels of adherence to a depression self-care intervention similar to those reported for other populations.

This study aims to develop learners’ thinking structures through associations, case based, and schematic method so that different knowledge structures have a role in influencing the structure of creative thinking. The learners have low mastery of physics materials since they are not given sufficient opportunity to build their own knowledge. They should be directed to approach each new problem or task with their prior knowledge, assimilate new information, and construct their own understanding. The design of this research was a quasi-experiment using purposive sampling. Data were analyzed using variance analysis. The design of this research was a quasi-experiment using purposive sampling. Data were analyzed using variance analysis. The learning process of problemsolving consists of: 1) identifying problems, 2) planning projects, 3) creating projects, 4) presenting projects, and 5) evaluating projects. From the results of this research, it can be concluded that problem-solving method can provide strong supports in developing the learners’ creative thinking skills as they can share their knowledge and interact with their friends and the environment. This learning activity also constitutes an appropriate technique to help the learners to develop problem solving knowledge and skills.

To assess disability more efficiently with less burden on the patient, the National Institutes of Health has developed the Patient Reported Outcomes Measurement Information System (PROMIS) Physical Function-an instrument based on item response theory and using computer adaptive testing (CAT). Initially, upper and lower extremity disabilities were not separated and we were curious if the PROMIS Physical Function CAT could measure upper extremity disability and the Quick Disability of Arm, Shoulder and Hand (QuickDASH). We aimed to find correlation between the PROMIS Physical Function and the QuickDASH questionnaires in patients with upper extremity illness. Secondarily, we addressed whether the PROMIS Physical Function and QuickDASH correlate with the PROMIS Depression CAT and PROMIS Pain Interference CAT instruments. Finally, we assessed factors associated with QuickDASH and PROMIS Physical Function in multivariable analysis. A cohort of 93 outpatients with upper extremity illnesses completed the QuickDASH and three PROMIS CAT questionnaires: Physical Function, Pain Interference, and Depression. Pain intensity was measured with an 11-point ordinal measure (0-10 numeric rating scale). Correlation between PROMIS Physical Function and the QuickDASH was assessed. Factors that correlated with the PROMIS Physical Function and QuickDASH were assessed in multivariable regression analysis after initial bivariate analysis. There was a moderate correlation between the PROMIS Physical Function and the QuickDASH questionnaire (r=-0.55, p<0.001). Greater disability as measured with the PROMIS and QuickDASH correlated most strongly with PROMIS Depression (r=-0.35, p<0.001 and r=0.34, p<0.001 respectively) and Pain Interference (r=-0.51, p<0.001 and r=0.74, p<0.001 respectively). The factors accounting for the variability in PROMIS scores are comparable to those for the QuickDASH except that the PROMIS Physical Function is influenced by other pain conditions while the QuickDASH is

People with severe mental illness have significantly poorer physical health compared to the general population; previous health screening studies conducted outside Asian countries have demonstrated the potential in addressing this issue. This case series aimed to explore the effects and utility of integrating an enhanced physical health screening programme for community dwelling patients with severe mental illness into routine clinical practice in Hong Kong. This study utilises a consecutive prospective case series design. The serious mental illness Health Improvement Profile (HIP) was used as a screening tool at baseline and repeated at 12 months follow-up. A total of 148 community-based patients with severe mental illness completed the study. At one year follow-up analysis showed a significant improvement in self-reported levels of exercise and a reduction in the numbers of patients prescribed medications for diabetes However, mean waist circumference increased at follow-up. In addition to the statistically significant results some general trends were observed, including: a lack of deterioration in most areas of cardiovascular risk; a reduction in medicines prescribed for physical health problems; and general improvements in health behaviours over the 12 month period. The findings demonstrate that using the HIP is feasible and acceptable in Hong Kong. The results of the enhanced physical health-screening programme are promising, but require further testing using a randomised controlled trial design in order to more confidently attribute the improvements in well-being and health behaviours to the HIP.

2013-01-01

Full Text Available In this paper, we present a GPU-accelerated hybrid system that solves ill-conditioned systems of linear equations exactly. Exactly means without rounding errors due to using integer arithmetics. First, we scale floating-point numbers up to integers, then we solve dozens of SLEs within different modular arithmetics and then we assemble sub-solutions back using the Chinese remainder theorem. This approach effectively bypasses current CPU floating-point limitations. The system is capable of solving Hilbert’s matrix without losing a single bit of precision, and with a significant speedup compared to existing CPU solvers.

Mental illness from the perspective of theoretical neuroscience.

Science.gov (United States)

Thagard, Paul

2008-01-01

Theoretical neuroscience, which characterizes neural mechanisms using mathematical and computational models, is highly relevant to central problems in the philosophy of psychiatry. These models can help to solve the explanation problem of causally connecting neural processes with the behaviors and experiences found in mental illnesses. Such explanations will also be useful for generating better classifications and treatments of psychiatric disorders. The result should help to eliminate concerns that mental illnesses such as depression and schizophrenia are not objectively real. A philosophical approach to mental illness based on neuroscience need not neglect the inherently social and historical nature of mental phenomena.

Good mental health is imperative to well-being. Symptoms of fatigue, chronic pain and poor sleep are common in people with mental illness and contribute to substantial loss of functioning. Physical exercise interventions have shown to decrease these symptoms in a range of populations; however, their possible association with physical activity related to day-to-day functioning have not been explored in people hospitalized with severe mental illness. Inpatients (n = 4) of a metropolitan mental health facility were fitted with an Actiwatch, which collected physical activity and sleep measures for an anticipated 14-day data collection period. During this time, morning and evening pain and fatigue scores were collected on an 11-point numerical rating scale. Significant associations were found between morning pain and morning fatigue scores (β = -0.44, P = 0.023), morning pain and physical activity (β = 12.34, P = 0.042), and physical activity and evening pain scores (β = 0.20, P = 0.017). Fatigue tended towards interfering more with quality of life than did pain, but this was not significant (P = 0.07). This study provided preliminary data suggesting associations between pain and fatigue, and intensity of pain and physical activity levels. This information can be used to generate hypotheses for future clinical trials. © 2013 John Wiley & Sons Ltd.

Partially specified physics problems: university students' attitudes and performance

International Nuclear Information System (INIS)

Marusic, M; Erceg, N; Slisko, J

2011-01-01

In this research we asked the fourth year students (N = 50) of a technical faculty of the University of Split (Republic of Croatia) to solve a partially specified physics problem related to gravitational force. The task for the students was to decide whether the situation described in the problem is feasible or not. Nevertheless, the formulation of the problem is such that it does not give students any explicit advice regarding what to calculate or how to judge the feasibility of the given situation in the real world. The research was carried out using a structured written exam method. The worksheet was structured in order to assess explicitly a few elements of the students' problem-solving performance. Based on their results, the examinees were classified into four categories, depending on what they could or could not accomplish during problem solving. A majority of students were not able to solve the given physical problem completely. A selection of students' and professors' observations is also included. Our results show that traditionally formulated numerical exercises, which are mostly used in physics teaching, do not develop students' abilities in higher-order thinking (i.e. planning, decision making or result evaluation) to a desirable extent. We suggest that partially specified problems should be given to students, both in problem-solving sessions and exams, in order to prepare them for dealing with ill-structured tasks in real life.

Illness perceptions in anorexia nervosa: a qualitative investigation.

Science.gov (United States)

Higbed, Laurie; Fox, John R E

2010-09-01

Anorexia nervosa (AN) is an eating disorder characterized by the egosyntonic nature of symptoms, denial of illness, and ambivalence about treatment engagement. Within the physical health literature, people's beliefs about their illness have been found to impact upon coping and treatment outcomes and this has largely been explored using the self-regulation model. This model has also been applied to mental health and more recently to AN, with beliefs about the disorder being associated with readiness to change. However, qualitative investigations have indicated that physical health models have limited applicability for assessing people's beliefs about mental illness. This may be particularly pertinent to AN, given the complexity of the disorder. Therefore, this study explored illness perceptions in AN using a qualitative design which was not restricted by a physical illness model but focused on personal models of AN from the perspective of those experiencing the disorder. Semi-structured interviews were conducted with thirteen participants who were currently in treatment for AN. Interview transcripts were analysed using grounded theory methodology. An interpretative theory of illness perceptions in AN was developed and comprised four related categories: 'making sense of AN', 'the relationship between AN and the self', 'the recovery struggle', and 'coping with treatment'. Patient's accounts transcended the dimensions offered by physical illness models, with the implication that methods for assessing illness beliefs in AN require adaptation for a full understanding to be gained and the complexity of perceptions to be captured.

People with severe mental illness (SMI) have considerable unmet physical health needs and an increased risk of early mortality. This cross-sectional survey utilized the Physical Health Attitude Scale (PHASe) to examine the attitudes, practices, and training needs of nurses towards physical health care of people with SMI in three Asian countries (Hong Kong, Japan, Qatar). Cross-country differences were explored and linear regression was used to investigate if nurses' attitudes and confidence were associated with their level of involvement in physical health care. A total of 481 questionnaires were returned. Hong Kong nurses were less involved in physical health care than those from Japan and Qatar. Nurses' attitudes and confidence were significant predictors of their participation in managing physical health. Compared with western countries, more nurses in this study felt that mental illness was a barrier to improving physical health. Three-quarters reported that they needed additional training in promoting cardiometabolic health. The perceived need for additional training in physical health care was held by Mental Health Nurses (MHN) irrespective of their type of nursing registration and nationality. Nurse educators and service providers should reconsider the physical health care training requirements of nurses working in mental health settings in order to improve the physical health of people with SMI.

Mental health comorbidities are common in HIV-infected veterans and can impact clinical outcomes for HIV. We examined the impact of mental health diagnoses on progression to AIDS-defining illness (ADI) and death in a large cohort of HIV-infected veterans who accessed care between 2001 and 2006. Retrospective cohort study using the national Veterans Health Administration (VHA) HIV Clinical Case Registry. We identified HIV-infected veterans initiating combination antiretroviral therapy (cART) within the VHA between 2000 and 2006. The prevalences of the following mental health diagnoses were examined: schizophrenia, bipolar disorder, depression, anxiety, and substance use disorder. Cox proportional hazards models were constructed to examine the relationship between mental health conditions and two outcomes, all-cause mortality and ADI. Models were computed before and after adjusting for confounding factors including age, race, baseline CD4 cell count, comorbidities and cART adherence. Among 9003 veterans receiving cART, 31% had no mental health diagnosis. Age, race, baseline comorbidity score, CD4, and cART adherence were associated with shorter time to ADI or death. All-cause mortality was more likely among veterans with schizophrenia, bipolar disorder and substance use, and ADI was more likely to occur among veterans with substance use disorder. Our results demonstrate the high prevalence of mental health diagnoses among HIV-infected veterans. In the era of highly active antiretroviral therapy, presence of psychiatric diagnoses impacted survival and development of ADI. More aggressive measures addressing substance abuse and severe mental illness in HIV-infected veterans are necessary.

Children's conceptions of mental illness: a naïve theory approach.

Fox, Claudine; Buchanan-Barrow, Eithne; Barrett, Martyn

2010-09-01

This paper reports two studies that investigated children's conceptions of mental illness using a naïve theory approach, drawing upon a conceptual framework for analysing illness representations which distinguishes between the identity, causes, consequences, curability, and timeline of an illness. The studies utilized semi-structured interviewing and card selection tasks to assess 6- to 11-year-old children's conceptions of the causes and consequences (Study 1) and the curability and timeline (Study 2) of different mental and physical illnesses/ailments. The studies revealed that, at all ages, the children held coherent causal-explanatory ideas about the causes, consequences, curability, and timeline of both mental and physical illnesses/ailments. However, while younger children tended to rely on their knowledge of common physical illnesses when thinking about mental illnesses, providing contagion and contamination explanations of cause, older children demonstrated differences in their thinking about mental and physical illnesses. No substantial gender differences were found in the children's thinking. It is argued that children hold coherent conceptions of mental illness at all ages, but that mental illness only emerges as an ontologically distinct conceptual domain by the end of middle childhood.

Shefer, Guy; Henderson, Claire; Howard, Louise M; Murray, Joanna; Thornicroft, Graham

2014-01-01

We conducted a qualitative study in the Emergency Departments (EDs) of four hospitals in order to investigate the perceived scope and causes of 'diagnostic overshadowing'--the misattribution of physical symptoms to mental illness--and other challenges involved in the diagnostic process of people with mental illness who present in EDs with physical symptoms. Eighteen doctors and twenty-one nurses working in EDs and psychiatric liaisons teams in four general hospitals in the UK were interviewed. Interviewees were asked about cases in which mental illness interfered with diagnosis of physical problems and about other aspects of the diagnostic process. Interviews were transcribed and analysed thematically. Interviewees reported various scenarios in which mental illness or factors related to it led to misdiagnosis or delayed treatment with various degrees of seriousness. Direct factors which may lead to misattribution in this regard are complex presentations or aspects related to poor communication or challenging behaviour of the patient. Background factors are the crowded nature of the ED environment, time pressures and targets and stigmatising attitudes held by a minority of staff. The existence of psychiatric liaison team covering the ED twenty-four hours a day, seven days a week, can help reduce the risk of misdiagnosis of people with mental illness who present with physical symptoms. However, procedures used by emergency and psychiatric liaison staff require fuller operationalization to reduce disagreement over where responsibilities lie.

Collective systems:physical and information exergies.

Energy Technology Data Exchange (ETDEWEB)

Robinett, Rush D. III (.; ); Wilson, David Gerald

2007-04-01

Collective systems are typically defined as a group of agents (physical and/or cyber) that work together to produce a collective behavior with a value greater than the sum of the individual parts. This amplification or synergy can be harnessed by solving an inverse problem via an information-flow/communications grid: given a desired macroscopic/collective behavior find the required microscopic/individual behavior of each agent and the required communications grid. The goal of this report is to describe the fundamental nature of the Hamiltonian function in the design of collective systems (solve the inverse problem) and the connections between and values of physical and information exergies intrinsic to collective systems. In particular, physical and information exergies are shown to be equivalent based on thermodynamics and Hamiltonian mechanics.

[Problems and strategies in the treatment of mental disorders in elderly patients with physical illness].

Science.gov (United States)

Wada, H

There is a high prevalence of mental disorders in the community population of older adults, especially in medical treatment facilities. Therefore, clinicians who treat geriatric patients cannot neglect the psychiatric vulnerability of the elderly population. The fragility of psychological functioning of the elderly is caused not only by psychological contributors, such as various kinds of experiences of loss, but also by biological factors such as decreases in neurotransmitters and in the number of neurons. Another point geriatric clinicians should pay attention to is the powerful mind-body connection in the elderly. Recent psychoneuroimmunological research demonstrates that depression or other types of emotional stress damages the immune system, which can induce some physical diseases. This is especially true for the elderly, who have weakened cell-mediated immune function and are more susceptible to influence by the damaged immune function caused by such psychiatric dysfunction. Also, depression in the elderly can often lead to malnutrition or dehydration, which can induce various kinds of physical illness. On the other hand, physical illness in the elderly can induce depression, because of the psychological vulnerability of the elderly. Due to the strong mind-body connection in the elderly, the availability of psychiatric care is essential. When providing psychiatric care for the elderly, the clinician should attend to all symptoms, not minimizing the importance of biological treatment, while also trying to support the elderly patients psychologically through acceptance of their need for interdependency and respect for their narcissism.

Student representational competence and self-assessment when solving physics problems

Directory of Open Access Journals (Sweden)

Noah D. Finkelstein

2005-10-01

Full Text Available Student success in solving physics problems is related to the representational format of the problem. We study student representational competence in two large-lecture algebra-based introductory university physics courses with approximately 600 participants total. We examined student performance on homework problems given in four different representational formats (mathematical, pictorial, graphical, verbal, with problem statements as close to isomorphic as possible. In addition to the homeworks, we examine students’ assessment of representations by providing follow-up quizzes in which they chose between various problem formats. As a control, some parts of the classes were assigned a random-format follow-up quiz. We find that there are statistically significant performance differences between different representations of nearly isomorphic statements of quiz and homework problems. We also find that allowing students to choose which representational format they use improves student performance under some circumstances and degrades it in others. Notably, one of the two courses studied shows much greater performance differences between the groups that received a choice of format and those that did not, and we consider possible causes. Overall, we observe that student representational competence is tied to both micro- and macrolevel features of the task and environment.

To obtain rapid and reproducible opinions that address mental illness stigma around the world. Random global Web users were exposed to brief questions, asking whether they interacted daily with someone with mental illness, whether they believed that mental illness was associated with violence, whether it was similar to physical illness, and whether it could be overcome. Over a period of 1.7 years, 596,712 respondents from 229 countries completed the online survey. The response rate was 54.3%. China had the highest proportion of respondents in daily contact with a person with mental illness. In developed countries, 7% to 8% of respondents endorsed the statement that individuals with mental illness were more violent than others, in contrast to 15% or 16% in developing countries. While 45% to 51% of respondents from developed countries believed that mental illness was similar to physical illness, only 7% believed that mental illness could be overcome. To test for reproducibility, 21 repeats of the same questions were asked monthly in India for 21 months. Each time, 10.1 ± 0.11% s.e., of respondents endorsed the statement that persons who suffer from mental illness are more violent than others, indicating strong reproducibility of response. This study shows that surveys of constructs such as stigma towards mental illness can be carried out rapidly and repeatedly across the globe, so that the impact of policy interventions can be readily measured. The method engages English speakers only, mainly young, educated males. Copyright © 2015 Elsevier B.V. All rights reserved.

Iterative methods for symmetric ill-conditioned Toeplitz matrices

Energy Technology Data Exchange (ETDEWEB)

Huckle, T. [Institut fuer Informatik, Muenchen (Germany)

1996-12-31

We consider ill-conditioned symmetric positive definite, Toeplitz systems T{sub n}x = b. If we want to solve such a system iteratively with the conjugate gradient method, we can use band-Toeplitz-preconditioners or Sine-Transform-peconditioners M = S{sub n}{Lambda}S{sub n}, S{sub n} the Sine-Transform-matrix and {Lambda} a diagonal matrix. A Toeplitz matrix T{sub n} = (t{sub i-j)}{sub i}{sup n},{sub j=1} is often related to an underlying function f defined by the coefficients t{sub j}, j = -{infinity},..,-1,0, 1,.., {infinity}. There are four cases, for which we want to determine a preconditioner M: - T{sub n} is related to an underlying function which is given explicitly; - T{sub n} is related to an underlying function that is given by its Fourier coefficients; - T{sub n} is related to an underlying function that is unknown; - T{sub n} is not related to an underlying function. Especially for the first three cases we show how positive definite and effective preconditioners based on the Sine-Transform can be defined for general nonnegative underlying function f. To define M, we evaluate or estimate the values of f at certain positions, and build a Sine-transform matrix with these values as eigenvalues. Then, the spectrum of the preconditioned system is bounded from above and away from zero.

Ausili, Davide; Masotto, Matteo; Dall'Ora, Chiara; Salvini, Lorena; Di Mauro, Stefania

2014-01-01

Chronic illnesses care represents a challenging issue for people well-being and future health systems' sustainability. Promotion of self-care is considered a key point for chronically ill patients' care. The aim of this literature was to explore: how self-care of chronic illness has been theoretically defined; how self-care can be assessed in clinical and research settings; what associations exist between self-care and health outcomes of chronically ill patients. A wide range of definitions and terminologies related to self-care of chronic illness has been found in the literature. Although some common elements useful to explain the concept of self-care have been identified, the physical, cognitive, emotional and social processes underlying self-care remain controversial and poorly defined. Valid and reliable disease-specific assessment tools have been developed and used in a growing number of studies; however, the lack of utilization of standardized instruments in clinical practice has been referred by many authors. Significant correlations between self-care of chronic illness and outcome measures e.g. general health status, quality of life and healthcare costs, are reported by a limited number of studies. Supporting patient self-care is recognized as a crucial factor in chronic illness care. A deeper analysis of variables and processes influencing self-care could help for a full description of the phenomenon. A systematic evaluation of self-care in health professionals' everyday clinical practice is strongly recommended. The development of general non-disease-specific assessment tools could facilitate the evaluation of complex patients, especially those with multiple co-morbidities. Although self-care has been recognized as a vital intermediate outcome, further large-scale studies clarifying the association between self-care and patients' and health systems' outcomes are needed.

Dependency in Critically Ill Patients

Full Text Available By necessity, critically ill patients admitted to intensive care units (ICUs have a high level of dependency, which is linked to a variety of negative feelings, such as powerlessness. However, the term dependency is not well defined in the critically ill patients. The concept of “dependency” in critically ill patients was analyzed using a meta-synthesis approach. An inductive process described by Deborah Finfgeld-Connett was used to analyze the data. Overarching themes emerged that reflected critically ill patients’ experience and meaning of being in dependency were (a antecedents: dependency in critically ill patients was a powerless and vulnerable state, triggered by a life-threatening crisis; (b attributes: the characteristic of losing “self” was featured by dehumanization and disembodiment, which can be alleviated by a “self”-restoring process; and (c outcomes: living with dependency and coping with dependency. The conceptual model explicated here may provide a framework for understanding dependency in critically ill patients.

The aim of this study was to explore the use of assessment strategy which can measure problem solving skills of pre-service teachers based on their cognitive style in basic physics course. The sample consisted of 95 persons (male = 15, female = 75). This study used an exploratory research with observation techniques by interview, questionnaire, and test. The results indicated that the lecturer only used paper-pencil test assessment strategy to measure pre-service teachers’ achievement and also used conventional learning strategy. It means that the lecturer did not measure pre-services’ thinking process in learning, like problem solving skills. One of the factors which can influence student problem solving skills is cognitive style as an internal factor. Field Dependent (FD) and Field Independent (FI) are two cognitive styles which were measured with using Group Embedded Figure Test (GEFT) test. The result showed that 82% of pre-service teachers were FD cognitive style and only 18% of pre-service teachers had FI cognitive style. Furthermore, these findings became the fundamental design to develop a problem solving assessment model to measure pre-service teachers’ problem solving skills and process in basic physics course.

Toward a theory of online communication in illness: concept analysis of illness blogs.

Heilferty, Catherine McGeehin

This paper is a report of a concept analysis of illness blogs and their relevance to nursing research on communication during illness. Blogs are being used by patients and family members to describe the experience of illness, but very little is known about this phenomenon. Seventeen English language databases and one Internet search engine were searched from 1990 to 2007 using the truncated term 'blog*'. Specific illness terms together with 'blog*', for example, blog* and diabetes; and blog* and cancer, were used to expand the search. Reports were included if they were of qualitative or quantitative research that included a definition of blogs or blogging and some identification or description of blog uses pertinent to the discipline. Specific emphasis was placed on blog use by individuals coping with illness experiences. 'Meta' writings by authors about their own blogging intentions and experiences were excluded. An illness blog is the online expression of the narrative of illness. Theoretical and operational definitions, defining attributes, uses, antecedents and consequences were developed. The literature search returned 45 works from 17 disciplines referring to the definition and uses of blogging. Support is offered from the review of literature and analysis of the concept for the development of a theory of online communication during illness. Reading and incorporating illness blogs into care will enhance patient-provider relationships. Analysis of the narratives being created online about the illness experience will contribute significantly to nursing's body of knowledge.

Health and Illness in History, Science and Society

Full Text Available Health is a fundamental human right. The World Health Organization defines it as a "state of complete physical, psychological and social well - being and not merely the absence of disease or infirmity". The health of individuals, however, is also linked to the environment in which they live and especially to their ability to adapt and integrate into their life context. The relationship with the environment is extremely important because it is that interaction that outlines the concept of normality compared to pathology. Such normality needs to be contextualised by gender, geographical origin and by the individuals’ living conditions: as a matter of fact, what is normal for a young person may differ from what is normal for a senior one. That is to say, the concept of health is indeed relative and it is the result of an interesting evolution of the concept of illness. From the first approaches - dealing with the mere treatment of the symptoms - to the promise of a free-from-pain society, science and economics have played a significant role in redefining the dualism health/ illness. The article reflects on these two concepts, health and illness, in history and nowadays, and discusses the future of the medical science.

Full Text Available Problem solving is a process conditioned by the development and application of efficient strategies. The aim of this research is to determine the level of verbal strategic approach to problem solving in children with mild intellectual disability (MID. The sample consists of 93 children with MID, aged between 10 and 14. Intellectual abilities of the examinees are within the defined range for mild intellectual disability (AM=60.45; SD=7.26. The examinees with evident physical, neurological, and emotional disorders were not included in the sample. The closed 20 Questions Test (20Q was used to assess the development and use of verbal strategy, where the examinee is presented with a poster containing 42 different pictures, and instructed to guess the picture selected by the examiner by asking no more than 20 closed questions. Test χ2, and Spearman and Pearson's correlation coefficient were used in statistical analysis. Research results indicate that most children with MID, aged between 10 and 14, use non-efficient strategy in solving the 20 Questions Test. Although strategic approach to problem solving is present in most children (72%, more than half of the examinees (53.5% use an inadequate strategy. Most children with MID have the ability to categorize concepts, however, they do not use it as a strategy in problem solving.

Self-reported health measures are important indicators used by clinicians and researchers for the evaluation of health interventions, outcome assessment of clinical studies, and identification of health needs to improve resource allocation. However, the application of self-reported health measures relies on developing reliable and valid instruments that are suitable across diverse populations. The main objective of this study is to evaluate the construct validity of the SF-12v.2, an instrument for measuring self-rated physical and mental health, for homeless adults with mental illness. Various interventions have been aimed at improving the health of homeless people with mental illness, and the development of valid instruments to evaluate these interventions is imperative. We measured self-rated mental and physical health from a quota sample of 575 homeless people with mental illness using the SF-12v2, EQ-5D, Colorado Symptoms Index, and physical/mental health visual analogue scales. We examined the construct validity of the SF-12v2 through confirmatory factor analyses (CFA), and using ANOVA/correlation analyses to compare the SF-12v2 to the other instruments to ascertain discriminant/convergent validity. Our CFA showed that the measurement properties of the original SF-12v2 model had a mediocre fit with our empirical data (χ2 = 193.6, df = 43, p physical and mental health status for a homeless population with mental illness.

Nearly 13% of the U.S. population is comprised of foreign-born individuals, with Somalis constituting one of the largest resettled groups. Research suggests that, among Somali refugees, rates of mental illness are high. Yet research shows Somalis underutilize mental health services. Understanding their perceptions of mental illness and its cures may help practitioners to design more effective treatments for this population. Thus, this pilot study investigated Somali refugees' perceptions of mental illness and its treatments. Using purposive sampling, this qualitative study interviewed 20 Somali refugees using a semi-structured interview guide. Qualitative analysis yielded participants' perceptions of mental illness through their descriptions of physical symptoms accompanying mental illness, the stigma of mental illness, causes of mental illness, medical and non-medical treatments for mental illness, spirit possession causing mental illness, and the Qur'an as treatment for mental illness. Such information may help practitioners in the United States approach Somali clients in the most culturally coherent manner.

We investigated the treatment effect of psychodynamic short-term therapy complemented with bodywork on patients who presented with physical illness at the Research Clinic for Holistic Medicine in Copenhagen. Psychodynamic short-term therapy was complemented with bodywork (Marion Rosen) to help patients confront old emotional pain from childhood trauma(s). Patients were measured with a five-item quality of life and health questionnaire (QOL5), a one-item questionnaire of self-assessed quality of life (QOL1), and four questions on self-rated ability to love and to function sexually, socially, and at work (ability to sustain a full-time job). Most of the patients had chronic pain that could not be alleviated with drugs. Results showed that 31 patients with the experience of being severely physically ill (mostly from chronic pain), in spite of having consulted their own general practitioner, entered the study. The holistic approach and body therapy accelerated the therapy dramatically and no significant side effects were detected. After the intervention, 38.7% did not feel ill (1.73 treatment responders, the treatment seemingly provided lasting benefits.

Costanzo, Cari; Verghese, Abraham

2018-05-01

The privilege of examining a patient is a skill of value beyond its diagnostic utility. A thorough physical examination is an important ritual that benefits patients and physicians. The concept of embodiment helps one understand how illness and pain further define and shape the lived experiences of individuals in the context of their race, gender, sexuality, and socioeconomic status. Understanding ritual in medicine, including the placebo effects of such rituals, reaffirms the centrality of the physical examination to the process of building strong physician-patient relationships.

Patients discharged from Critical Care suffer from excessive longer term morbidity and mortality. Physical and mental health measures of quality of life show a marked and immediate fall after admission to Critical Care with some recovery over time. However, physical function is still significantly reduced at 6 months. The National Institute for Health and Care Excellence clinical guideline on rehabilitation after critical illness, identified the need for high-quality randomised controlled trials to determine the most effective rehabilitation strategy for critically ill patients at risk of critical illness-associated physical morbidity. In response to this, we will conduct a randomised controlled trial, comparing physiotherapy aimed at early and intensive patient mobilisation with routine care. We hypothesise that this intervention will improve physical outcomes and the mental health and functional well-being of survivors of critical illness. 308 adult patients who have received more than 48 h of non-invasive or invasive ventilation in Critical Care will be recruited to a patient-randomised, parallel group, controlled trial, comparing two intensities of physiotherapy. Participants will be randomised to receive either standard or intensive physiotherapy for the duration of their Critical Care admission. Outcomes will be recorded on Critical Care discharge, at 3 and 6 months following initial recruitment to the study. The primary outcome measure is physical health at 6 months, as measured by the SF-36 Physical Component Summary. Secondary outcomes include assessment of mental health, activities of daily living, delirium and ventilator-free days. We will also include a health economic analysis. The trial has ethical approval from Newcastle and North Tyneside 2 Research Ethics Committee (11/NE/0206). There is a Trial Oversight Committee including an independent chair. The results of the study will be submitted for publication in peer-reviewed journals and

Transport equation solving methods

Granjean, P.M.

1984-06-01

This work is mainly devoted to Csub(N) and Fsub(N) methods. CN method: starting from a lemma stated by Placzek, an equivalence is established between two problems: the first one is defined in a finite medium bounded by a surface S, the second one is defined in the whole space. In the first problem the angular flux on the surface S is shown to be the solution of an integral equation. This equation is solved by Galerkin's method. The Csub(N) method is applied here to one-velocity problems: in plane geometry, slab albedo and transmission with Rayleigh scattering, calculation of the extrapolation length; in cylindrical geometry, albedo and extrapolation length calculation with linear scattering. Fsub(N) method: the basic integral transport equation of the Csub(N) method is integrated on Case's elementary distributions; another integral transport equation is obtained: this equation is solved by a collocation method. The plane problems solved by the Csub(N) method are also solved by the Fsub(N) method. The Fsub(N) method is extended to any polynomial scattering law. Some simple spherical problems are also studied. Chandrasekhar's method, collision probability method, Case's method are presented for comparison with Csub(N) and Fsub(N) methods. This comparison shows the respective advantages of the two methods: a) fast convergence and possible extension to various geometries for Csub(N) method; b) easy calculations and easy extension to polynomial scattering for Fsub(N) method [fr

People with mental illness experience high levels of morbidity and mortality from physical disease compared to the general population. Our primary aim was to compare how people with severe mental illness (SMI; i.e. schizophrenia-spectrum disorders and bipolar disorder) and non-psychotic mental illness perceive their: (i) global physical health, (ii) barriers to improving physical health, (iii) physical health with respect to important aspects of life and (iv) motivation to change modifiable high-risk behaviours associated with coronary heart disease. A secondary aim was to determine health locus of control in these two groups of participants. People with SMI and non-psychotic mental illness were recruited from an out-patient adult mental health service in London. Cross-sectional comparison between the two groups was conducted by means of a self-completed questionnaire. A total of 146 people participated in the study, 52 with SMI and 94 with non-psychotic mental illness. There was no statistical difference between the two groups with respect to the perception of global physical health. However, physical health was considered to be a less important priority in life by people with SMI (OR 0.5, 95% CI 0.2-0.9, p = 0.029). There was no difference between the two groups in their desire to change high risk behaviours. People with SMI are more likely to have a health locus of control determined by powerful others (p locus of control may provide a theoretical focus for clinical intervention in order to promote a much needed behavioural change in this marginalised group of people.

The economic dispatch (ED) is an essential optimization task in the power generation system. It is defined as the process of allocating the real power output of generation units to meet required load demand so as their total operating cost is minimized while satisfying all physical and operational constraints. This paper introduces a novel optimization which named as Swarm based Mean-variance mapping optimization (MVMOS). The technique is the extension of the original single particle mean-variance mapping optimization (MVMO). Its features make it potentially attractive algorithm for solving optimization problems. The proposed method is implemented for three test power systems, including 3, 13 and 20 thermal generation units with quadratic cost function and the obtained results are compared with many other methods available in the literature. Test results have indicated that the proposed method can efficiently implement for solving economic dispatch.

mortalidade proporcional por causa mal definida entre as áreas estudadas. O aumento observado entre 1980 e 2002 na classificação de óbitos por causa mal definida pelo primeiro avaliador no Estado de São Paulo indica uma importante piora na qualidade do preenchimento da declaração de óbito nessa instância. São necessárias investigações adicionais para esclarecer as causas dessa mudança.OBJECTIVE: To investigate the proportion of deaths with an ill-defined cause in the Brazilian state of São Paulo between 1980 and 2002, taking into account the influence of autopsies on this proportion. METHOD: Data on the number of deaths were obtained from the Brazilian Ministry of Health. The communities of the state of São Paulo were divided into three groups: (1 municipalities with a service to verify the cause of death (and that may conduct an autopsy, (2 municipalities without a cause of death verification service, and (3 the region of Baixada Santista, which had an extremely large increase in the proportion of deaths from ill-defined causes between 1980 and 1995. The impact of autopsies on the proportion of deaths with an ill-defined cause was defined based on the classification made by the first physician evaluating the cause of death, that is, the physician who referred the case to the verification service for autopsy or who completed the death certificate without referring the case to the verification service. Deaths from external causes were excluded, since autopsy is mandatory in these cases. The following were evaluated: (1 proportion of cases classified by the first evaluating physician as having an ill-defined cause, (2 proportion of autopsies in relation to the total number of deaths (except from external causes, and (3 proportion of deaths classified as ill-defined by the first evaluating physician but explained by the autopsy. RESULTS: The proportion of deaths classified by the first evaluating physician as having an ill-defined cause increased over the 1980

Physiotherapy has been widely defined as a healthcare profession that assesses, diagnoses, treats, and works to prevent disease and disability through physical means. The World Confederation for Physical Therapy describes physiotherapy as providing services to people and populations to develop, maintain, and restore maximum movement and functional ability throughout the lifespan. Physiotherapists working with terminally ill patients face a myriad of ethical issues which have not been substantially discussed in bioethics especially in the African perspective. In the face of resource limitation in developing countries, physiotherapy seems to be a cost-effective means of alleviating pain and distressing symptoms at the end-of-life, ensuring a more dignified passage from life to death, yet referrals to physiotherapy are not timely. Following extensive literature search using appropriate keywords, six core ethical themes related to physiotherapy in terminally ill patients were identified and using the four principles of bioethics (patient's autonomy, beneficence, nonmaleficence, and justice), an ethical analysis of these themes was done to highlight the ethical challenges of physiotherapists working in a typical African setting such as Nigeria.

The paper compares PASCAL and FORTRAN for problem solving in the physical sciences, due to requests NASA has received to make PASCAL available on the Numerical Aerodynamic Simulator (scheduled to be operational in 1986). PASCAL disadvantages include the lack of scientific utility procedures equivalent to the IBM scientific subroutine package or the IMSL package which are available in FORTRAN. Advantages include a well-organized, easy to read and maintain writing code, range checking to prevent errors, and a broad selection of data types. It is concluded that FORTRAN may be the better language, although ADA (patterned after PASCAL) may surpass FORTRAN due to its ability to add complex and vector math, and the specify the precision and range of variables.

2004-01-01

This paper examines the needs and stress reactions of children of mentally ill parents, as well as coping and resilience. The study is based on the interviews of six 9-11 years old children and narratives of seventeen female grown up children of mentally ill parents. The younger and older children of the mentally ill parents had not been informed about their parent's illness. The illness of the parent aroused a variety of emotions in them. The children used both practical problem solving and emotional coping mechanisms. Informal social support was available to them but seldom from the public services. It is recommended that professionals in mental health and child welfare services clarify their roles when working with mentally ill parents. The best interest of the child and the parenting they need should be carefully assessed. Open care measures should be offered to families early enough to prevent serious child welfare and mental problems.

People diagnosed with mental illness have shorter lives and poorer physical health, compared to the general population. These health inequities are usually viewed at an individual and clinical level, yet there is little research on the views of mental health consumers on clinical factors in broader contexts. To elicit the views of consumers of mental health services regarding their physical health and experiences of accessing physical health-care services. Qualitative exploratory design involving focus groups. The research was conducted in the Australian Capital Territory. Participants were consumers of mental health services. The Commission on Social Determinants of Health Framework was drawn on to lead deductive analysis of focus group interview transcripts. Issues impacting consumers included poverty, the neglect of public services and being treated as second-class citizens because of diagnosis of mental illness and/or experiencing a psychosocial disability. These factors were connected with significant barriers in accessing physical health care, including the quality and relevance of health provider communication, especially when the broader contexts of mental health consumer's lives are not well understood. These findings suggest the Commission on Social Determinants of Health Framework could be utilized in research and policy, and may provide an effective platform for exploring better health communication with mental health consumers regarding this neglected health inequity. © 2017 The Authors Health Expectations Published by John Wiley & Sons Ltd.

The physical health of people with serious mental illness (SMI) has become a focal area of research. The aim of the present study was to ascertain the attention and distribution of research from within Australia on physical illness and SMI co-occurrence, and to identify gaps. A scoping review of peer-reviewed research literature from Australia, published between January 2000 and March 2014, was undertaken through an electronic literature search and coding of papers to chart trends. Four trends are highlighted: (i) an almost threefold increase in publications per year from 2000-2006 to 2007-2013; (ii) a steady release of literature reviews, especially from 2010; (iii) health-related behaviours, smoking, integrated-care programmes, and antipsychotic side-effects as the most common topics presented; and (iv) paucity of randomized, controlled trials on integrated-care models. Despite a marked increase in research attention to poorer physical health, there remains a large gap between research and the scale of the problem previously identified. More papers were descriptive or reviews, rather than evaluations of interventions. To foster more research, 12 research gaps are outlined. Addressing these gaps will facilitate the reduction of inequalities in physical health for people with SMI. Mental health nurses are well placed to lead multidisciplinary, consumer-informed research in this area. © 2015 Australian College of Mental Health Nurses Inc.

Creative Problem Solving and Social Cooperation of Effective Physical Therapy Practice: A Pioneer Study and Overview

Directory of Open Access Journals (Sweden)

Eli Carmeli

2003-01-01

Full Text Available Action research (AR has an important role to play in educating physical therapists. Increasing efforts should be encouraged to instigate AR programs in physical therapy practice and clinical education. Such programs commonly require considerable effort and understanding by clinical instructors, and require adoption of new educational methods. AR programs can lead physical therapists and clinicians to be more questioning and reflective in evaluating practical questions regarding patient therapy and education. The purpose of this article is to educate the readers on the importance of AR and to provide a few relevant references on that topic. A specific study is described in this paper in which physical therapy clinical instructors participated in a structured workshop designed to demonstrate the values of AR and how such values can be incorporated in teaching their students. AR can lead to improved therapist-patient interaction and help solve specific practical problems arising during therapy sessions.

2017-12-01

Full Text Available This study investigated the effect of contextualized teaching on students’ problem solving skills in physics through a quasi-experimental approach. Problem solving performance of students was described quantitatively through their mean problem solving scores and problem solving skills level. A unit plan patterned from the cognitive apprenticeship approach and contextualized using maritime context of ship stability was implemented on the experimental group while the control group had the conventional lecture method. Pre and post assessment, which is a researcher-developed word problem assessment, was administered to both groups. Results indicated increased problem solving mean scores (p < 0.001, problem solving skill level (p < 0.001 of the experimental group while the control group increased only their problem solving skill level (p = 0.008. Thus, contextualized teaching can improve the problem solving performance of students. This study recommends using contextualization using other physics topics where other contexts can be applied.

At present, the main method to solve RPCs is the Least Squares Estimation. But when coefficients has a large number or the distribution of the control points is not even, the classical least square method loses its superiority due to the ill-conditioning problem of design matrix. Condition Index and Variance Decomposition Proportion (CIVDP) is a reliable method for diagnosing the multicollinearity among the design matrix. It can not only detect the multicollinearity, but also can locate the parameters and show the corresponding columns in the design matrix. In this paper, the CIVDP method is used to diagnose the ill-condition problem of the RFM and to find the multicollinearity in the normal matrix

The present study investigated the psychophysiological inter- and intra-individual processes that mediate the linkage between childhood and/or adolescent socioeconomic adversities and adult health outcomes. Specifically, the proposed model examined the roles of youth depressive symptoms and body mass index (BMI) trajectories as mediators that explain the link between early adversity and young adults' general health and physical illnesses after controlling for gender, race or ethnicity, and earlier general health reports. Using a nationally representative sample of 12,424 from National Longitudinal Study of Adolescent Health (Add Health), this study used growth curve modeling to consider both the severity (initial level) and the change over time (deterioration or elevation) as psychophysiological mediators, thereby acknowledging multiple facets of depressive symptoms and BMI trajectories as psychophysiological mediators of early adversity to adult health. Results provide evidence for (1) the influence of early childhood and early adolescent cumulative socioeconomic adversity on both the initial levels and changes over time of depressive symptoms and BMI and (2) the independent influences depressive symptoms and BMI trajectories on the general health and the physical illnesses of young adults. These findings contribute valuable knowledge to existing research by elucidating how early adversity exerts an enduring long-term influence on physical health problems in young adulthood; furthermore, this information suggests that effective intervention and prevention programs should incorporate multiple facets (severity and change over time) of multiple mechanisms (psychological and physiological).

The poor physical health of people with a severe mental illness is well documented and health professionals' attitudes, knowledge and skills are identified factors that impact on clients' access to care for their physical health needs. An evaluation was conducted to determine: (i) mental health nurses' attitudes and beliefs about providing physical health care; and, (ii) the effect that participant demographics may have on attitudes to providing physical health care. It was hypothesized that workplace culture would have the largest effect on attitudes. Nurses at three health services completed the "Mental health nurses' attitude towards the physical health care of people with severe and enduring mental illness survey" developed by Robson and Haddad (2012). The 28-item survey measured: nurses' attitudes, confidence, identified barriers to providing care and attitudes towards clients smoking cigarettes. The findings demonstrated that workplace culture did influence the level of physical health care provided to clients. However, at the individual level, nurses remain divided and uncertain where their responsibilities lie. Nursing leadership can have a significant impact on improving clients' physical health outcomes. Education is required to raise awareness of the need to reduce cigarette smoking in this client population. © 2016 Australian College of Mental Health Nurses Inc.

Severe loneliness in community-dwelling aging adults with mental illness.

Loboprabhu, Sheila; Molinari, Victor

2012-01-01

Successful aging involves adapting to changing needs. The 2009 U.S. Census noted that 43% of adult Americans are single and that the oldest-old population is the most rapidly growing aging segment. Geriatric, lonely, hopeless individuals are at high risk for depression and suicide. Lonely individuals fail to adapt to their circumstances; and physical and mental illness place them at risk for neglect, morbidity, and mortality. The authors discuss the role of attachment in the individual's subjective experience of loneliness and suggest how attachment theory can be used to guide interventions to improve the individual's self-esteem, coping, and problem-solving abilities. This article also discusses the use of multimodal therapy, including psychodynamic, interpersonal, and cognitive-behavior therapy and coping skills training, to improve the individual's ability to adapt to the surrounding environment and to reintegrate into the community.

Full Text Available Abstract Background Capturing dimensions of physical activity relevant to patients may provide a unique perspective for clinical studies of chronically ill patients. However, the quality of the development of existing instruments is uncertain. The aim of this systematic review was to assess the development process of patient-reported outcome (PRO instruments including their initial validation to measure physical activity in chronically ill or elderly patient populations. Methods We conducted a systematic literature search of electronic databases (Medline, Embase, Psychinfo, Cinahl and hand searches. We included studies describing the original development of fully structured instruments measuring dimensions of physical activity or related constructs in chronically ills or elderly. We broadened the population to elderly because they are likely to share physical activity limitations. At least two reviewers independently conducted title and abstract screening and full text assessment. We evaluated instruments in terms of their aim, items identification and selection, domain development, test-retest reliability, internal consistency, validity and responsiveness. Results Of the 2542 references from the database search and 89 from the hand search, 103 full texts which covered 104 instruments met our inclusion criteria. For almost half of the instruments the authors clearly described the aim of the instruments before the scales were developed. For item identification, patient input was used in 38% of the instruments and in 32% adaptation of existing scales and/or unsystematic literature searches were the only sources for the generation of items. For item reduction, in 56% of the instruments patient input was used and in 33% the item reduction process was not clearly described. Test-retest reliability was assessed for 61%, validity for 85% and responsiveness to change for 19% of the instruments. Conclusions Many PRO instruments exist to measure

It is known that self-reported health (SRH) declines with increasing age and that comorbidity increases with age. We wished to examine how age transfers its effect to SRH through comorbid disease and mental illness and whether these processes remained stable from 1994 until 2008. The hypothesis is that ageing and/or the increased age-related burden of pathology explains the declining SRH. The Tromsø Study (TS) is a cohort study using a survey approach with repeated physical examinations. It was conducted in the municipality of Tromsø, Norway, from 1974 to 2008. A total of 21 199 women and 19 229 men participated. SRH is the outcome of interest. We calculated and compared the effect sizes of age, comorbidity and mental health symptoms using multimediator analysis based on OLS regression. Ageing had a negative impact on SRH, but the total effect of age decreased from 1994 to 2007. We assessed the direct effect of age and then the proportion of indirect age-related effects through physical illness and mental health symptoms on the total effect. The direct effect of age represented 79.3% of the total effect in 1994 and decreased to 58.8% in 2007. Physical illness emerged as an increasingly important factor and increased its influence from 15.7% to 41.2% of the total effect. Age alone had a protective effect on mental health symptoms and this increased (2.5% to 17.3%), but we found a stronger association between mental health symptoms and physical disease in the later waves of the study (increasing from 3.7% to 14.8%). The results suggest that the effect on SRH of mental health symptoms caused by physical illness is an increasing public health problem. Treatment and care for specific medical conditions must therefore focus more strongly on how these conditions affect the patient's mental health and address these concerns accordingly.

Barrowclough, C; Lobban, F; Hatton, C; Quinn, J

2001-11-01

Although carers' reactions to schizophrenic illness in a close family member may have important implications for the patient and for themselves, little is known of factors that influence the way carers respond. In the area of physical health problems, people's models of their illness or illness representations have been found to be related to the ways they react and cope with their illness. This study examines the use of a modified form of the Illness Perception Questionnaire (IPQ) to investigate illness models in a sample of carers of schizophrenia patients. Forty-seven carers participated. The psychometric properties of the modified IPQ were examined, and a number of carer and patient outcomes were investigated in relation to carer scores on the illness identity, consequences, control-cure and timeline subscales of the modified IPQ. These outcomes included measures of carer distress and burden, expressed emotion dimensions, and patient functioning. The modified IPQ was found to be a reliable measure of carers' perceptions of schizophrenia. Carer functioning, the patient-carer relationship and patient illness characteristics were associated with different dimensions of illness perceptions. The findings support the proposal that carer cognitive representations of the illness may have important implications for both carer and patient outcomes in schizophrenia.

Concepts of Illness Among the Swahili of Lamu, Kenya.

Gearhart, Rebecca; Abdulrehman, Munib Said

2014-07-01

The Swahili of Lamu, Kenya, understand illness as the result of a spiritual imbalance caused by personal transgression or an attack by harmful forces directed by an envious person. Another underlying component of the Swahili concept of illness is that each person's physical body operates in conjunction with personal attributes that are fixed at birth and determine moral character, behavior, and predisposition to ailments. When physical symptoms occur, the Swahili focus on identifying the human or supernatural entity that caused the illness in consultation with a range of healers who specialize in a variety of curing strategies. Two case studies illustrate how culturally congruent nursing care can be achieved when health care providers understand the Swahili framework of diagnosing and treating illness. © The Author(s) 2013.

Mandatory physical exercise for the prevention of mental illness in medical students

Directory of Open Access Journals (Sweden)

Robert A. Bitonte

2014-09-01

Full Text Available Medical students experience higher rates of mental illness than the general population. With competition rising for success in medical school, and residency, increasing incidence of distress are leading this population to experience higher rates of thoughts of dropping out of school, and even suicide. Since many stigmas deter medical students from receiving mental health counseling, such as the perceived inability to handle the stresses of medical school, and the potential lack of competitiveness for residencies if reported, prevention of mental illness may be a better course to take in reducing prevalence in this population. Regular exercise has demonstrated a positive effect on not only promoting physical health, but also mental health. Exercise encourages a healthy mood, positive self esteem, and better cognition, while decreasing the chances of depression, anxiety, and burnout. Implementing exercise time into medical school curriculums, just like the basic sciences, albeit for less time in the day, could provide a feasible way to ensure that all students are taking time to partake in this important activity for their well being. Though medical schools are rigid with attempts to make changes in their curriculum, thirty minutes a day, three to five times a week of exercise of the students’ choice not only is more cost effective than counseling, but it also reduces the chances that they will experience burnout, which if left untreated could transcend into a compromised training experience.

Assessing student expertise in introductory physics with isomorphic problems. II. Effect of some potential factors on problem solving and transfer

Directory of Open Access Journals (Sweden)

Chandralekha Singh

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

Notwithstanding that psychological distress and illness perceptions are important in determining outcomes in rheumatic diseases, few studies investigated these variables in primary Sjögren's syndrome (pSS). We aimed to compare illness perceptions and psychological distress in patients with pSS, systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) and to test whether their associations with health-related quality of life (HRQoL) are similar in these groups of patients. In 57 patients with pSS, 75 with SLE and 199 with RA, we administered the Patient Health Questionnaire (PHQ-9), the Symptom Check-List and the Brief-Illness Perception Questionnaire to assess psychological variables and the World Health Organization Quality of Life Instrument, Short-Form to assess HRQoL. Hierarchical regression models determined the associations of psychological variables with HRQoL after adjusting for demographic variables and clinical parameters. The prevalence of clinically significant depressive symptoms (PHQ-9 ≥ 10) was 24.6 % in pSS, 29.3 % in SLE and 25.1 % in RA. Patients with pSS showed little understanding of their disease (comprehensibility) and attributed more symptoms to their illness (identity) compared with the other groups of patients. Illness perceptions and depressive symptoms were independently associated with physical HRQoL in a similar pattern in all three groups. In pSS, however, the patients' worries about the consequences of their illness was a stronger correlate of physical HRQoL than pain. These findings indicate that psychological factors are important correlates of HRQoL in these disease groups and encourage the design of psycho-educational therapies targeting disease-related cognitions in pSS in an attempt to improve patient's physical HRQoL.

Chronotope Disruption as a Sensitizing Concept for Understanding Chronic Illness Narratives

Science.gov (United States)

2014-01-01

Objectives: This article aims to elaborate chronotope disruption —a changed relation to time and space— as a sensitizing concept for understanding chronic illness narratives. Methods: Sixteen men and 16 women with Type 2 diabetes were purposefully sampled. Each was interviewed about his or her experience of diabetes self-management using the biographical-narrative interview method. Transcripts were inspected for key moments defined as emotionally laden stories relevant to the purpose of the research. We present dialogically inflected discursive analysis of exemplar extracts. Results: The analysis demonstrates how the concept of chronotope disruption helps identify, and understand, important aspects of patients’ chronic illness narratives. First, we investigate how medical advice can conflict with embodied experience and how progressive bodily deterioration can provoke a reevaluation of past illness (self-mis)management. Second, the increasing temporal and spatial intrusion of chronic illness into participants’ lives is examined. Finally, we focus on the masquerade of health as an attempt to manage, hide, or deny that one is physically challenged. Conclusions: Chronotope disruption offers a useful sensitizing concept for approaching chronic illness narratives and around which to organize analytical insights and to develop practice. Chronotope analysis fills an important gap in the science through compensating current health sciences’ focus on rationality, cognition, and prospective time (prediction) with a patient-oriented focus on emotionality, embodiment, and retrospective time (nostalgia). Chronotope disruption could be used to develop practice by gaining empathic understanding of patients’ life-worlds and provides a tool to examine how new technologies change the way in which the chronically ill have “being” in the world.

Full Text Available Mastery of the concepts of physics students can be measured by its ability to solve the problems of physics. Problem solving ability is one component that must be owned by the students as a physics teacher candidates. Based on the results of initial observations, it is known that the problem solving ability of students is still low, especially associated with the use of physics concepts to solve problems. Therefore, the ability of problem solving should be trained in teaching as a form of scaffolding for students. Scaffolding can be done through the method of Socratic dialogue which is the provision of structured questions to help students find answers to the problems of physics using the right concept. This type of research is the Classroom Action Research  with two cycles were performed on physics student teachers in the subjects Physics 1 with a fluid material. Improved problem solving ability was measured using test items at the end of the cycle. The results qualitatively show their developments and increased activity in the classroom compared to learning before the action. These results are supported quantitatively by an increase in average test scores of the first cycle of 70.00 into 75.86 in the second cycle. Keywords: problem solving, socratic dialogue Penguasaan konsep fisika mahasiswa dapat diukur dari kemampuannya dalam memecahkan permasalahan fisika (problem solving.

PC-based process distribution to solve iterative Monte Carlo simulations in physical dosimetry

Leal, A.; Sanchez-Doblado, F.; Perucha, M.; Rincon, M.; Carrasco, E.; Bernal, C.

2001-01-01

A distribution model to simulate physical dosimetry measurements with Monte Carlo (MC) techniques has been developed. This approach is indicated to solve the simulations where there are continuous changes of measurement conditions (and hence of the input parameters) such as a TPR curve or the estimation of the resolution limit of an optimal densitometer in the case of small field profiles. As a comparison, a high resolution scan for narrow beams with no iterative process is presented. The model has been installed on a network PCs without any resident software. The only requirement for these PCs has been a small and temporal Linux partition in the hard disks and to be connecting by the net with our server PC. (orig.)

The clinical effects of varying pharmacokinetic exposures of antibiotics (antibacterials and antifungals) on outcome in infected critically ill patients are poorly described. A large-scale multi-centre study (DALI Study) is currently underway describing the clinical outcomes of patients achieving pre-defined antibiotic exposures. This report describes the protocol. DALI will recruit over 500 patients administered a wide range of either beta-lactam or glycopeptide antibiotics or triazole or echinocandin antifungals in a pharmacokinetic point-prevalence study. It is anticipated that over 60 European intensive care units (ICUs) will participate. The primary aim will be to determine whether contemporary antibiotic dosing for critically ill patients achieves plasma concentrations associated with maximal activity. Secondary aims will compare antibiotic pharmacokinetic exposures with patient outcome and will describe the population pharmacokinetics of the antibiotics included. Various subgroup analyses will be conducted to determine patient groups that may be at risk of very low or very high concentrations of antibiotics. The DALI study should inform clinicians of the potential clinical advantages of achieving certain antibiotic pharmacokinetic exposures in infected critically ill patients.

We compared health-related quality of life (HRQOL) in incident (≤1 year since diagnosis), mid-term (>1-5 years since diagnosis), and long-term (>5 years since diagnosis) cases of mental and physical chronic illness with the general population and assessed the modifying effects of age and gender on the association between HRQOL and illness duration. Data from the 2007 Australian National Health and Mental Wellbeing Survey were used. HRQOL was captured by the Assessment of Quality of Life Scale 4D. Multivariable linear regression analyses compared HRQOL of individuals with different duration of illnesses with those who did not have the condition of interest. The 8841 survey respondents were aged 16-85 years (median 43 years, 50.3% female). For the overall sample, worse HRQOL was associated with incident (P = 0.049) and mid-term (P = 0.036) stroke and long-term depression (P illness is most apparent in stroke and mental illness and differs between age groups.

We present a minimal extension of the Standard Model (SM) providing a consistent picture of particle physics from the electroweak scale to the Planck scale and of cosmology from inflation until today. Three right-handed neutrinos N_i, a new color triplet Q and a complex SM-singlet scalar σ, whose vacuum expectation value υ_σ∝10"1"1 GeV breaks lepton number and a Peccei-Quinn symmetry simultaneously, are added to the SM. At low energies, the model reduces to the SM, augmented by seesaw generated neutrino masses and mixing, plus the axion. The latter solves the strong CP problem and accounts for the cold dark matter in the Universe. The inflaton is comprised by a mixture of σ and the SM Higgs and reheating of the Universe after inflation proceeds via the Higgs portal. Baryogenesis occurs via thermal leptogenesis. Thus, five fundamental problems of particle physics and cosmology are solved at one stroke in this unified Standard Model-Axion-Seesaw-Higgs portal inflation (SMASH) model.

Full Text Available In this study we assessed differences in new and repeat prescriptions of psycho-tropics between patients receiving prescriptions for drugs to treat a common chronic disease and people without such prescriptions. The study used the databases of two Dutch health insurance companies (3 million people. We selected all Dutch men and women aged 45 and older who were registered for six consecutive years (1999–2004. Our analyses both found a consistent relation between psycho-tropics on the one hand and physical illness on the other. People with multi-morbidity were prescribed these drugs most often, especially men and those younger than 65. Epidemiological studies showed a prevalence of depression among people with multi-morbidity to be twice as high as among people without such conditions. According to recent guidelines non-drug treatment may be the first therapy option for patients with non severe depression. If prescribed for a long time, benzodiazepine prescriptions are especially known to be addictive. Our data raise the question to what extent patients with a chronic physical disease suffering from co-occurring mental problems are prescribed psycho-tropics in accord with the guidelines that also advise mental support in case of non severe mental problems. Further research can answer this important question.

The eight-item Brief Illness Perception Questionnaire is used as a screening instrument in physical therapy to assess mental defeat in patients with acute low back pain, besides patient perception might determine the course and risk for chronic low back pain. However, the psychometric properties of the Brief Illness Perception Questionnaire in common musculoskeletal disorders like acute low back pain have not been adequately studied. Patients' perceptions vary across different populations and affect coping styles. Thus, our aim was to determine the internal consistency, test-retest reliability and validity of the Dutch language version of the Brief Illness Perception Questionnaire in acute non-specific low back pain patients in primary care physical therapy. A non-experimental cross-sectional study with two measurements was performed. Eighty-four acute low back pain patients, in multidisciplinary health care center in Dutch primary care with a sample mean (SD) age of 42 (12) years, participated in the study. Internal consistency (Cronbach's α) and test-retest procedures (Intraclass Correlation Coefficients and limits of agreement) were evaluated at a one-week interval. The concurrent validity of the Brief Illness Perception Questionnaire was examined by using the Mental Health Component of the Short Form 36 Health Survey. The Cronbach's α for internal consistency was 0.73 (95% CI, 0.67 - 0.83); and the Intraclass Correlation Coefficient test-retest reliability was acceptable: 0.72 (95% CI, 0.53 - 0.82), however, the limits of agreement were large. The Intraclass Correlation Coefficient measuring concurrent validity 0.65 (95% CI, 0.46 - 0.80). The Dutch version of the Brief Illness Perception Questionnaire is an appropriate instrument for measuring patients' perceptions in acute low back pain patients, showing acceptable internal consistency and reliability. Concurrent validity is adequate, however, the instrument may be unsuitable for detecting changes in low

BACKGROUND: Coping and illness perception are considered to be important contributors in the relationship between physical and psychological factors in rheumatoid arthritis (RA). AIMS: The aim of this study was to examine the complex relationship of coping and illness perception on physical and psychological factors in RA using a structural model. METHODS: We assessed coping, illness perception, depression, anxiety, pain, arthritis-related disability and perceived social support in 68 adults with RA. RESULTS: Greater pain was detected in patients with increased scores on passive coping scale, greater severity of physical disability and increased depression and anxiety. Illness perception was found to be a mediator in the relationship between physical disability and passive coping on one hand and depression, anxiety and pain on the other. CONCLUSIONS: The hypothesised structural model has proven to be a useful paradigm for understanding the associations between multiple factors in RA presentation: clinical, emotional, personal and cognitive.

Full Text Available Introduction: Social support is the perception that one is cared for, has assistance available from significant others and its benefit is by buffering stress by influencing the ability to adjust and live with illness. Social support can uplift the quality and subjective wellbeing of people. The objective of this study was to examine the perceived social support and factors influencing it among mentally ill patients. Methods: A descriptive cross-sectional study was carried out. Ninety cases aged more than 18 years visiting outpatient of psychiatric department and diagnosed as a case of mental illness for at least a year were included. Instruments used were self-developed proforma and Multidimensional Scale of Perceived Social Support. Interview technique was used to collect the data. Results: Majority (60% of the patients perceive social support from family, 28% of the patients perceive social support from significant others. Regression analysis showed that the perceived social support is influenced by employment status, type of family one lives in and physical illness. It is not influenced by gender, subjective financial status and frequency of hospitalization. Conclusion: Perceived social support is influenced by employment status, type of family one lives in and physical illness. Majority (60% of the patients perceive social support from family.

The duality of health technology in chronic illness: how designers envision our future.

Science.gov (United States)

Lehoux, Pascale

2008-06-01

This essay critically explores the role of technological innovation in the constitution of chronic states and illness. Drawing on the co-construction of technology and society perspective, it focuses more specifically on the way in which innovation designers envisage the enhancement of the chronically ill and build certain kinds of socio-technical configuration to deal with chronic illness. Using the case of ;intelligent distance patient monitoring' as an illustration, the paper argues that technology creates as much as it solves the problem of chronic illness. Technology is recursively embedded in chronic illness and it generates dual effects: it constrains and sustains users' daily practices. Only by recognizing technology's duality and eventually transcending it will research and policy initiatives be able to deal creatively and responsibly with the design of our future health experiences.

According to the restructuring hypothesis, insight problem solving typically progresses through consecutive stages of search, impasse, insight, and search again for someone, who solves the task. The order of these stages was determined through self-reports of problem solvers and has never been verified behaviorally. We asked whether individual analysis of problem solving attempts of participants revealed the same order of problem solving stages as defined by the theory and whether their subjective feelings corresponded to the problem solving stages they were in. Our participants tried to solve the Five-Square problem in an online task, while we recorded the time and trajectory of their stick movements. After the task they were asked about their feelings related to insight and some of them also had the possibility of reporting impasse while working on the task. We found that the majority of participants did not follow the classic four-stage model of insight, but had more complex sequences of problem solving stages, with search and impasse recurring several times. This means that the classic four-stage model is not sufficient to describe variability on the individual level. We revised the classic model and we provide a new model that can generate all sequences found. Solvers reported insight more often than non-solvers and non-solvers reported impasse more often than solvers, as expected; but participants did not report impasse more often during behaviorally defined impasse stages than during other stages. This shows that impasse reports might be unreliable indicators of impasse. Our study highlights the importance of individual analysis of problem solving behavior to verify insight theory.

2009-01-01

A methodology for solving eigenvalue problems for the multigroup neutron transport equation in 1D slab geometry is presented. In this paper we formulate and compare different variants of nonlinear multi-level iteration methods. They are defined by means of multigroup and effective one-group low-order quasi diffusion (LOQD) equations. We analyze the effects of utilization of the effective one-group LOQD problem for estimating the eigenvalue. We present numerical results to demonstrate the performance of the iteration algorithms in different types of reactor-physics problems. (authors)

Elderly migrants constitute a considerable share of global return migration; nevertheless, literature on the health aspects of the return migration among these migrants is still scarce. This study explores the significance of return migration among elderly, chronically ill Bosnian refugees from Denmark and the role of health issues in their decision to return. It is based on semi-structured interviews with 33 elderly, chronically ill Bosnian refugees who have moved back to Bosnia and Herzegovina, and 10 elderly, chronically ill Bosnian refugees who have remained in Denmark. The interviews show that physical health, in the sense of the absence of illness and easy access to necessary health-care services and medicines, was not highly prioritized when the decision was made whether or not to return. However, if health is regarded more broadly as involving more than mere physical health and the absence of illness, health did matter. Viewed as physical, social and mental well-being in line with WHO's definition of health, health was indeed one of the most important factors when the decision to return was made.

There has been increasing interest for investigating the role of motivation in physical activity among people with severe mental illness (SMI). Autonomous motivation has been suggested to have a potentially important role in adoption and maintenance of physical activity. However, the knowledge about factors that facilitate autonomous motivation among people with SMI is scarce. The aim of this study was to examine factors associated with motivation for physical activity as well as the relationships between motivation, physical activity and health-related quality of life in individuals with SMI that were currently physically active. A cross-sectional design was used, and 88 participants were recruited from a public health network promoting physical activity for people with SMI. They answered a questionnaire package consisting of scales measuring psychological need support - psychological need satisfaction - and motivation for physical activity, physical activity and health-related quality of life. The majority of participants reported to be in regular physical activity. Associations between variables were tested according to the self-determination theory process model. Structural equation modelling yielded good fit of the process model to the data. Specifically, a need-supportive environment was positively associated with psychological need satisfaction, while psychological need satisfaction was positively associated with autonomous motivation and mental health-related quality of life, and negatively associated with controlled motivation and amotivation. Physical activity was positively associated with autonomous motivation and physical health-related quality of life, and negatively associated with amotivation. This study indicates that individuals with SMI can be regularly physically active when provided with suitable opportunities. Furthermore, the present results suggest that it is vital for health-care practitioners to emphasise creating a need

Objective To review how disability can develop in older adults with critical illness and to explore ways to reduce long-term disability following critical illness. Data Sources Review of the literature describing post-critical illness disability in older adults and expert opinion. Results We identified 19 studies evaluating disability outcomes in critically ill patients age 65 years and older. Newly acquired disability in activities of daily living, instrumental activities of daily living and mobility activities was commonplace among older adults who survived a critical illness. Incident dementia and less-severe cognitive impairment was also highly prevalent. Factors related to the acute critical illness, intensive care unit practices such as heavy sedation, physical restraints and immobility as well as aging physiology and coexisting geriatric conditions can combine to result in these poor outcomes. Conclusion Older adults who survive critical illness suffer physical and cognitive declines resulting in disability at greater rates than hospitalized, non-critically ill and community dwelling older adults. Interventions derived from widely available geriatric care models in use outside of the ICU, which address modifiable risk factors including immobility and delirium, are associated with improved functional and cognitive outcomes and can be used to complement ICU-focused models such as the ABCDEs.

2016-05-01

Background Published clinical problem solving exercises have emerged as a common tool to illustrate aspects of the clinical reasoning process. The specific clinical reasoning terms mentioned in such exercises is unknown. Objective We identified which clinical reasoning terms are mentioned in published clinical problem solving exercises and compared them to clinical reasoning terms given high priority by clinician educators. Methods A convenience sample of clinician educators prioritized a list of clinical reasoning terms (whether to include, weight percentage of top 20 terms). The authors then electronically searched the terms in the text of published reports of 4 internal medicine journals between January 2010 and May 2013. Results The top 5 clinical reasoning terms ranked by educators were dual-process thinking (weight percentage = 24%), problem representation (12%), illness scripts (9%), hypothesis generation (7%), and problem categorization (7%). The top clinical reasoning terms mentioned in the text of 79 published reports were context specificity (n = 20, 25%), bias (n = 13, 17%), dual-process thinking (n = 11, 14%), illness scripts (n = 11, 14%), and problem representation (n = 10, 13%). Context specificity and bias were not ranked highly by educators. Conclusions Some core concepts of modern clinical reasoning theory ranked highly by educators are mentioned explicitly in published clinical problem solving exercises. However, some highly ranked terms were not used, and some terms used were not ranked by the clinician educators. Effort to teach clinical reasoning to trainees may benefit from a common nomenclature of clinical reasoning terms.

2010-02-01

The physical health of people with serious mental illness is a cause of growing concern to clinicians. Life expectancy in this population may be reduced by up to 25 years and patients often live with considerable physical morbidity that can dramatically reduce quality of life and contribute to social exclusion. This study sought to determine whether the serious mental illness health improvement profile [HIP], facilitated by mental health nurses [MHNs], has the clinical potential to identify physical morbidity and inform future evidence-based care. Retrospective documentation audit and qualitative evaluation of patients' and clinicians' views about the use of the HIP in practice. A nurse-led outpatient medication management clinic, for community adult patients with serious mental illness in Scotland. 31 Community patients with serious mental illness seen in the clinic by 2 MHNs trained to use the HIP. All 31 patients, 9 MHNs, 4 consultant psychiatrists and 12 general practitioners [GPs] (primary care physicians) participated in the qualitative evaluation. A retrospective documentation audit of case notes for all patients where the HIP had been implemented. Semi-structured interviews with patients and their secondary care clinicians. Postal survey of GPs. 189 Physical health issues were identified (mean 6.1 per patient). Items most frequently flagged 'red', suggesting that intervention was required, were body mass index [BMI] (n=24), breast self-examination (n=23), waist circumference (n=21), pulse (n=14) and diet (n=13). Some rates of physical health problems observed were broadly similar to those reported in studies of patients receiving antipsychotics in primary care but much lower than those reported in epidemiological studies. Individualised care was planned and delivered with each patient based on the profile. 28 discreet interventions that included providing advice, promoting health behavioural change, performing an electrocardiogram and making a referral to

Individuals with severe mental illness (SMI) are less physically active than the general population. One important barrier contributing to this inactivity is lack of motivation. The aim of this paper is to systematically review all cross-sectional literature on motivation for physical activity among people with SMI and to use the results as basis for guidance on how mental health nurses can facilitate motivation for physical activity. Systematic searches of seven databases were conducted from database inception to February 2015. Studies were eligible if they included participants with SMI and reported data on motivation for physical activity. In total, 21 articles were included and over half them were published in 2011 or later. The present results indicate preliminary evidence of how the motivational processes do not differ between individuals with SMI and the general population, and that they are independent of diagnosis, medication, age, gender, and body mass index. Results from the current systematic review can give some tentative guidance on how to facilitate motivation for physical activity within mental health-care. However, there is still a great need for developing and examining practical strategies that can enhance adoption and adherence of physical activity among people with SMI. © 2016 Australian College of Mental Health Nurses Inc.

The Lightweight Integrating Multi-physics Environment (LIME) is a software package for creating multi-physics simulation codes. Its primary application space is when computer codes are currently available to solve different parts of a multi-physics problem and now need to be coupled with other such codes. In this report we define a common domain language for discussing multi-physics coupling and describe the basic theory associated with multiphysics coupling algorithms that are to be supported in LIME. We provide an assessment of coupling techniques for both steady-state and time dependent coupled systems. Example couplings are also demonstrated.

Full Text Available Abstract Background The clinical effects of varying pharmacokinetic exposures of antibiotics (antibacterials and antifungals on outcome in infected critically ill patients are poorly described. A large-scale multi-centre study (DALI Study is currently underway describing the clinical outcomes of patients achieving pre-defined antibiotic exposures. This report describes the protocol. Methods DALI will recruit over 500 patients administered a wide range of either beta-lactam or glycopeptide antibiotics or triazole or echinocandin antifungals in a pharmacokinetic point-prevalence study. It is anticipated that over 60 European intensive care units (ICUs will participate. The primary aim will be to determine whether contemporary antibiotic dosing for critically ill patients achieves plasma concentrations associated with maximal activity. Secondary aims will compare antibiotic pharmacokinetic exposures with patient outcome and will describe the population pharmacokinetics of the antibiotics included. Various subgroup analyses will be conducted to determine patient groups that may be at risk of very low or very high concentrations of antibiotics. Discussion The DALI study should inform clinicians of the potential clinical advantages of achieving certain antibiotic pharmacokinetic exposures in infected critically ill patients.

Full Text Available Abstract Background People with long-term serious mental illness live with severe and debilitating symptoms that can negatively influence their health and quality of life, leading to outcomes such as premature mortality, morbidity and obesity. An interplay of social, behavioural, biological and psychological factors is likely to contribute to their poor physical health. Participating in regular physical activity could bring symptomatic improvements, weight loss benefits, enhanced wellbeing and when undertaken in a community-based group setting can yield additional, important social support benefits. Yet poor uptake of physical activity by people with serious mental illness is a problem. This review will systematically search, appraise and synthesise the existing evidence that has explored the experience of community-based physical activity initiation and key features of social support within these contexts by adults with schizophrenia, bipolar affective disorder, major depressive disorder or psychosis using the meta-ethnography approach. This new understanding may be key in designing more acceptable and effective community-based group PA programmes that meet patients’ need and expectations.

Control of pain management is an important up-stream process in fibromyalgia (FM) mechanisms. To investigate whether adapted physical activity (APA) could change the illness perception in relation to the FM personality profile. Thirty-seven women with FM allocated randomly: 19 treatment group (TG) and 18 control group (CG). Interventions: exercises program included ten sessions, two times for week for one hour each and observation for CG. Scales: Illness Perception Questionnaire-revisited (IPQ-r) for the mental representation of the disease, Minnesota Multiphasic Personality Inventory profiles (MMPI-2) for personality tool and Fibromyalgia Impact Questionnaire (FIQ) for function, impact and symptoms. Outcome assessments were performed before rehabilitation treatment (T0) than at the end (T1), and a follow-up 12 weeks after treatment (T2). APA was efficacy to improve FIQ values in TG at T1 and T2 test days (P = 0.014). Changes in IPQ-R values in T2 were not significant. All patients presented a baseline T-score≥65 in at least one of the basic and content MMPI-2 scales (Hy, D, Hs and Hea and Anx). APA was efficacy in FM, but further research to differentiate between illness experience rather than focus ona strict personality profile are necessary.

RCTs involving a total of 2723 primary trial participants. Two review authors extracted data from 26 studies. We analysed data using two categories. First, we analysed data by each medical condition across all treatment classes at two time points (immediately post-treatment and the first available follow-up). Second, we analysed data by each treatment class (cognitive behavioural therapy (CBT), family therapy (FT), problem solving therapy (PST) and multisystemic therapy (MST)) across all medical conditions at two time points (immediately post-treatment and the first available follow-up). We assessed treatment effectiveness on six possible outcomes: parent behaviour, parent mental health, child behaviour/disability, child mental health, child symptoms and family functioning. Across all treatment types, psychological therapies that included parents significantly improved child symptoms for painful conditions immediately post-treatment. Across all medical conditions, cognitive behavioural therapy (CBT) significantly improved child symptoms and problem solving therapy significantly improved parent behaviour and parent mental health immediately post-treatment. There were no other effects at post-treatment or follow-up. The risk of bias of included studies is described. There is no evidence on the effectiveness of psychological therapies that include parents in most outcome domains of functioning, for a large number of common chronic illnesses in children. There is good evidence for the effectiveness of including parents in psychological therapies that reduce pain in children with painful conditions. There is also good evidence for the effectiveness of CBT that includes parents for improving the primary symptom complaints when available data were included from chronic illness conditions. Finally, there is good evidence for the effectiveness of problem solving therapy delivered to parents on improving parent problem solving skills and parent mental health. All effects are
