Emotions are the central process of motivation and play a key role in adaptive behavior in humans. Although cognitive-behavioral therapy stresses the importance of changing both cognition and behavior, there is growing emphasis on direct therapeutic work on emotions and emotional processing, as problematic emotional processes are at the core of nearly all psychic disorders. This type of work is the goal of emotion-focused psychotherapy, which centers on direct change of problematic emotions, especially those which are usually suppressed resp. overregulated by the patient. This paper examines the basic phobic/emotional conflict, the problematic emotional processes arising from this conflict, and the importance to cognitive-behavioral therapy of their potentially integrative role.

Problematic hypoglycemia, defined as two or more episodes per year of severe hypoglycemia or as one episode associated with impaired awareness of hypoglycemia, extreme glycemic lability, or major fear and maladaptive behavior, is a challenge, especially for patients with long-standing type 1 diabetes. Individualized therapy for such patients should include a composite target: optimal glucose control without problematic hypoglycemia. Therefore, we propose a tiered, four-stage algorithm based on evidence of efficacy given the limitations of educational, technological, and transplant interventions. All patients with problematic hypoglycemia should undergo structured or hypoglycemia-specific education programs (stage 1). Glycemic and hypoglycemia treatment targets should be individualized and reassessed every 3-6 months. If targets are not met, one diabetes technology-continuous subcutaneous insulin infusion or continuous glucose monitoring-should be added (stage 2). For patients with continued problematic hypoglycemia despite education (stage 1) and one diabetes technology (stage 2), sensor-augmented insulin pumps preferably with an automated low-glucose suspend feature and/or very frequent contact with a specialized hypoglycemia service can reduce hypoglycemia (stage 3). For patients whose problematic hypoglycemia persists, islet or pancreas transplant should be considered (stage 4). This algorithm provides an evidence-informed approach to resolving problematic hypoglycemia; it should be used as a guide, with individual patient circumstances directing suitability and acceptability to ensure the prudent use of technology and scarce transplant resources. Standardized reporting of hypoglycemia outcomes and inclusion of patients with problematic hypoglycemia in studies of new interventions may help to guide future therapeutic strategies. © 2015 by the American Diabetes Association.

Neuroticism and Negative Urgency in Problematic Alcohol Use: A Pilot Study.

Papachristou, Harilaos; Nederkoorn, Chantal; Jansen, Anita

2016-09-18

Problematic alcohol use is common among university students and personality might account for individual differences in developing this maladaptive behavior. Two personality dispositions implicated in problematic alcohol use are negative urgency and neuroticism. However, the relationship of these traits to problematic alcohol use is unclear. In college students high neuroticism is not directly linked to problematic alcohol use. On the other hand, the experience of emotional distress in people high in neuroticism could impair the capacity for impulse control. Loss of impulse control under conditions of negative affect could trigger impulsive drinking and problematic alcohol use in the long run. We investigated this idea by testing whether negative urgency mediates the relationship of neuroticism to problematic alcohol use. Participants were 60 undergraduate university students who completed the Urgency subscale of the Urgency, (lack of) Premeditation, (lack of) Perseverance, Sensation Seeking, and Positive Urgency Impulsive Behaviour scale (UPPS-P), the Alcohol Use Disorders Identification Test (AUDIT), and the Neuroticism subscale of the Eysenck Personality Questionnaire Revised short form (EPQ-RSS). The results confirmed our hypothesis as we found an indirect effect of negative urgency on the relationship between neuroticism and problematic alcohol use. It appears that it is not distress but the tendency to act rashly when distressed that is important in developing problematic alcohol drinking in university students.

Psychiatrists′ work with sickness certification: frequency, experiences and severity of the certification tasks in a national survey in Sweden

PubMed Central

2012-01-01

Background Many psychiatrists are involved in sickness certification of their patients; however, there is very limited knowledge about this aspect of their work. The objective of this study was to explore frequencies of problematic issues in the sickness certification tasks and experiences of severity regarding these problematic issues among psychiatrists. Methods A cross-sectional nationwide questionnaire study to all physicians in Sweden. The 579 specialists in psychiatry who answered the questionnaire, were under 65 years of age, worked mainly in psychiatric care, and had consultations involving sickness certification at least once a week were included. Results The frequency of problematic sickness certification consultations a few times per year or more often was considered by 87.3% of the psychiatrists; 11.7% handle such cases at least once a week. A majority (60.9%) reported ‘not having enough time with the patient’ at least once a week. The psychiatrists had access to several categories of professionals in their daily work. More than one third certified unnecessarily long sick-leave periods at least once a month due to waiting times for Social Insurance Office investigations or for treatments or investigations within health care. Conclusion The majority found it problematic to assess the level and duration of work incapacity, but also other types of problems like unnecessarily long sick-leave periods due to different types of waiting times. The findings have implications for different kinds of organisational and managerial support and training in sickness certification issues, like guidance to assess the level and duration of work incapacity.

Internet use is an integral part of our everyday activities; however, Internet use may become problematic and harmful in a minority of cases. The majority of reported prevalence rates of problematic Internet use refer to adolescent samples, whereas epidemiological studies on representative adult populations are lacking. This study aimed to reveal the prevalence and characteristics of problematic Internet use in Slovenia. Problematic Internet Use Questionnaire (PIUQ) was included in European Health Interview Study (EHIS) on representative Slovenian sample. The frequency of Internet use and problematic Internet use were both assessed. 59.9% of Slovenian adult population uses the Internet daily, and 3.1% are at risk of becoming problematic Internet users, 11% in the age group from 20 to 24 years. Those being at risk for becoming problematic Internet users are younger (mean age 31.3 vs. 48.3 for non-problematic users), more likely to be males (3.6% of males, whereas 2.6% of females are affected), students (12.0%), unemployed (6.3%) or unable to work (8.7%), single (6.5%), with high education (4.5%). Regression analysis revealed that the strongest predictor of being at risk for problematic Internet use is age (ß=-0.338, p<0.001); followed by high educational level (ß=0.145; p<0.001) and student status (ß=0.136; p<0.001). 3.1% of Slovenian adult population are at risk of becoming problematic Internet users, whereas 3 out of 20 Slovenian adolescents aged from 18 to 19 years are at risk (14.6%). Prevention programs and treatment for those affected are paramount, especially for the young generation.

Problematic alcohol use is associated with neuropsychological consequences, including cognitive biases. The goal of the study was to explore the moderating role of executive control and readiness to change on the relationship between alcohol use and cognitive biases in light and problematic drinkers with and without mild to borderline intellectual disability (MBID). Participants (N = 112) performed the visual dot probe task to measure the strength of the cognitive biases. Executive control was measured using two computerised tasks for working memory capacity (Corsi block-tapping task) and inhibitory control (Go/No-go task). Readiness to change was measured using the Readiness to Change Questionnaire. No cognitive biases or executive dysfunctions were found in problematic drinkers. Working memory capacity and inhibitory control were impaired among individuals with MBID, irrespective of severity of alcohol use-related problems. Executive control and readiness to change did not moderate the relationship between alcohol use and cognitive biases. The results fail to support the dual-process models of addiction, but results need to be treated with caution given the problematic psychometric qualities of the visual dot probe task. Implementing a neurocognitive assessment and protocols in the treatment of substance use disorders seems premature. © 2016 John Wiley & Sons Ltd.

Yee (2006) found three motivational factors-achievement, social, and immersion-underlying play in massively multiplayer online role-playing games ("MMORPGs" or "MMOs" for short). Subsequent work has suggested that these factors foster problematic or addictive forms of play in online worlds. In the current study, we used an online survey of respondents (N = 252), constructed and also interpreted in reference to ethnography and interviews, to examine problematic play in the World of Warcraft (WoW; Blizzard Entertainment, 2004-2013). We relied on tools from psychological anthropology to reconceptualize each of Yee's three motivational factors in order to test for the possible role of culture in problematic MMO play: (a) For achievement, we examined how "cultural consonance" with normative understandings of success might structure problematic forms of play; (b) for social, we analyzed the possibility that developing overvalued virtual relationships that are cutoff from offline social interactions might further exacerbate problematic play; and (c) in relation to immersion, we examined how "dissociative" blurring of actual- and virtual-world identities and experiences might contribute to problematic patterns. Our results confirmed that compared to Yee's original motivational factors, these culturally sensitive measures better predict problematic forms of play, pointing to the important role of sociocultural factors in structuring online play.

The aim of the study was to identify problematic situations in using zebra crossings. They were identified from photo documentations comprising film sequences and the perspectives of people with dementia. The aim was also to identify how they would understand, interpret and act in these problematic situations based on their previous experiences and linked to the film sequences.A qualitative grounded theory approach was used. Film sequences from five zebra crossings were analysed. The same film sequences were used as triggers in two focus group interviews with persons with dementia. Individual interviews with three informants were also performed.The core category, the hazard of meeting unfolding problematic traffic situations when only one layer at a time can be kept in focus, showed how a problematic situation as a whole consisted of different layers of problematic situations. The first category, adding layers of problematic traffic situations to each other, was characterized by the informants' creation of a problematic situation as a whole. The different layers were described in the subcategories of layout of streets and zebra crossings, weather conditions, vehicles and crowding of pedestrians. The second category, actions used to meet different layers of problematic traffic situations, was characterized by avoiding problematic situations, using traffic lights as reminders and security precautions, following the flow at the zebra crossing and being cautious pedestrians.In conclusion, as community-dwelling people with dementia commonly are pedestrians, it is important that health care professionals and caregivers take their experiences and management of problematic traffic situations into account when providing support. © The Author(s) 2014.

This national survey aims, on the one hand, to perform a comparative analysis of working conditions, job strain and burnout of Belgian nurses, physicists and radiation oncologists working in radiotherapy and, on the other hand, to explore the role of emotional labor in the development of stress and burnout. We used the Working Conditions and Control Questionnaire, the Positive and Negative Occupational States Inventory, the Maslach Burnout Inventory, the negative work-home interaction subscale of the Survey Work-Home Interaction Nijmegen (NEGWHI), Perceived Organizational Support Scale and Emotional Labor Scale. One open question asked about problematic job situations. Ninety-eight nurses and physicists participated (33 % response rate), in addition to 66 radiation oncologists from a previous study. Although global scores of working conditions, job strain and burnout corresponded to normal scores, comparative analysis identified physicists as focus group concerning job strain and burnout. Moreover, nurses and physicists surface acting was a good predictor of job strain (β=0.22, P=0.01), emotional exhaustion (β=0.32, P<0.001) and depersonalization (β=0.43, P<0.001). Nevertheless, perceived organizational support was a moderator in this relation. Radiotherapy employees were in the norms. The importance of organizational support was demonstrated to avoid potential health problems, for workers experiencing high levels of emotional demands.

2011-01-01

It has been recognized both by the scientific community and within the framework of social policies in Europe that the physical and psychosocial working environments pose potential risks for workers and organizational wellbeing. In particular psychosocial risks concern aspects of the design and management of work and its social and organizational contexts which have the potential for causing psychological or physical problems. This article examines the psychosocial risk factors of several types of Italian Public Administration offices (municipal, provincial, regional, central government, university, police headquarters, chamber of commerce, etc.) with the aim of obtaining a picture of the most problematic risk factors for each type. The participants of this survey consisted of about 23,500 employees of different types of Public Administration offices. The Multidimensional Organizational Health Questionnaire (MOHQ, 3) was used to collect the data. Results from ANOVA indicated that perceptions of fairness and job demands were the most problematic risk factors. Perception of safety at work was another problematic risk factor in specific types of work. The results revealed a high perception of stress in all workers over the entire range of the public administration offices studied.

Foucault's notion of problematization: a methodological discussion of the application of Foucault's later work to nursing research.

PubMed

Frederiksen, Kirsten; Lomborg, Kirsten; Beedholm, Kirsten

2015-09-01

This study takes its point of departure in an oft-voiced critique that the French philosopher Michel Foucault gives discourse priority over practice, thereby being deterministic and leaving little space for the individual to act as an agent. Based on an interpretation of the latter part of Foucault's oeuvre, we argue against this critique and provide a methodological discussion of the perception that Foucault's method constitutes, primarily, discourse analysis. We argue that it is possible to overcome this critique of Foucault's work by the application of methodological tools adapted from Foucault's later writings and his diagnosis of his own work as studies of forms of problematization. To shed light on the possibilities that this approach offers to the researcher, we present a reading of aspects of Foucault's work, with a focus on his notion of forms of problematization. Furthermore, we elaborate on concepts from his so-called genealogical period, namely 'the dispositive', strategy and tactics. Our interpretation is supported by examples from a study of the emergence of Danish nursing education, which is based on an analytical framework that we developed in the light of an interpretation of aspects of Foucault's work. © 2015 John Wiley & Sons Ltd.

Hooked on Facebook: The Role of Social Anxiety and Need for Social Assurance in Problematic Use of Facebook.

Lee-Won, Roselyn J; Herzog, Leo; Park, Sung Gwan

2015-10-01

There is a growing concern that excessive and uncontrolled use of Facebook not only interferes with performance at school or work but also poses threats to physical and psychological well-being. The present research investigated how two individual difference variables--social anxiety and need for social assurance--affect problematic use of Facebook. Drawing on the basic premises of the social skill model of problematic Internet use, we hypothesized that social anxiety and need for social assurance would be positively correlated with problematic use of Facebook. Furthermore, it was predicted that need for social assurance would moderate the relationship between social anxiety and problematic use. A cross-sectional online survey was conducted with a college student sample in the United States (N=243) to test the proposed hypotheses. Results showed that both social anxiety and need for social assurance had a significant positive association with problematic use of Facebook. More importantly, the data demonstrated that need for social assurance served as a significant moderator of the relationship between social anxiety and problematic Facebook use. The positive association between social anxiety and problematic Facebook use was significant only for Facebook users with medium to high levels of need for social assurance but not for those with a low level of need for social assurance. Theoretical and practical implications of these findings were discussed.

Problematizing as a scientific endeavor

The work of physics learners at all levels revolves around problems. Physics education research has inspired attention to the forms of these problems, whether conceptual or algorithmic, closed or open response, well or ill structured. Meanwhile, it has been the work of curriculum developers and instructors to develop these problems. Physics education research has supported these efforts with studies of students problem solving and the effects of different kinds of problems on learning. In this article we argue, first, that developing problems is central to the discipline of physics. It involves noticing a gap of understanding, identifying and articulating its precise nature, and motivating a community of its existence and significance. We refer to this activity as problematizing, and we show its importance by drawing from writings in physics and philosophy of science. Second, we argue that students, from elementary age to adults, can problematize as part of their engaging in scientific inquiry. We present four cases, drawing from episodes vetted by a panel of collaborating faculty in science departments as clear instances of students doing science. Although neither we nor the scientists had problematizing in mind when screening cases, we found it across the episodes. We close with implications for instruction, including the value of helping students recognize and manage the situation of being confused but not yet having a clear question, and implications for research, including the need to build problematizing into our models of learning.

Characteristics of sick-listing cases that physicians consider problematic--analyses of written case reports.

The aim was to discern common characteristics in the sick-listing cases that physicians in general practice and occupational health services find problematic. Descriptive categorization within a narrative theoretical framework. Sickness-insurance course for physicians in general practice and occupational health services. A total of 195 case reports written by 195 physicians. Main outcome measures. Categories of features regarding medical, work, and social situation as well as medical interventions. Beside age and sex, the following information was often provided: family situation, stressful life events, occupation, problem at work, considerations concerning diagnoses, medical investigations, treatments, and vocational rehabilitation measures. Two-thirds of the patients had been sickness absent for more than a year. The most common type of case reports concerned women, employed in non-qualified nursing occupations, and sick listed due to mental disorders. The most common measures taken by the physicians were referrals to psychotherapy and/or physiotherapy, and prescribing antidepressants (SSRI). Facts about alcohol habits were rarely provided in the cases. Some of the circumstances, such as prolonged sick-listing, are likely to be more or less inevitable in problematic sick-listing cases. Other circumstances, such as stress-full life events, more closely reflect what the reporting physicians find problematic. The categories identified can be regarded as markers of problematic sick-listing cases in general practice and occupational health service.

The College of American Pathologists and the National Health Service (NHS) in the United Kingdom are merging their respective clinical terminologies, SNOMED RT and Clinical Terms Version 3, into a new terminology, SNOMED CT. This requires mapping concept descriptions between the two existing terminologies. During the mapping process, many descriptions were identified as being potentially problematic. They require further review by the SNOMED editorial process before either (1) being incorporated into SNOMED CT, or (2) retired from active use. This article presents data on the concept descriptions that were identified as needing further review during the early phases of SNOMED CT development. Based on this work, we describe fourteen types of problematic terminology content. Identifying problematic terminology content can be approached in a systematic manner. PMID:11825253

Reconciling the good patient persona with problematic and non-problematic humour: a grounded theory.

McCreaddie, May; Wiggins, Sally

2009-08-01

Humour is a complex phenomenon, incorporating cognitive, emotional, behavioural, physiological and social aspects. Research to date has concentrated on reviewing (rehearsed) humour and 'healthy' individuals via correlation studies using personality-trait based measurements, principally on psychology students in laboratory conditions. Nurses are key participants in modern healthcare interactions however, little is known about their (spontaneous) humour use. A middle-range theory that accounted for humour use in CNS-patient interactions was the aim of the study. The study reviewed the antecedents of humour exploring the use of humour in relation to (motivational) humour theories. Twenty Clinical Nurse Specialist-patient interactions and their respective peer groups in a country of the United Kingdom. An evolved constructivist grounded theory approach investigated a complex and dynamic phenomenon in situated contexts. Naturally occurring interactions provided the basis of the data corpus with follow-up interviews, focus groups, observation and field notes. A constant comparative approach to data collection and analysis was applied until theoretical sufficiency incorporating an innovative interpretative and illustrative framework. This paper reports the grounded theory and is principally based upon 20 CNS-patient interactions and follow-up data. The negative case analysis and peer group interactions will be reported in separate publications. The theory purports that patients' use humour to reconcile a good patient persona. The core category of the good patient persona, two of its constituent elements (compliance, sycophancy), conditions under which it emerges and how this relates to the use of humour are outlined and discussed. In seeking to establish and maintain a meaningful and therapeutic interaction with the CNS, patients enact a good patient persona to varying degrees depending upon the situated context. The good patient persona needs to be maintained within the interaction and is therefore reconciled with potentially problematic or non-problematic humour use. Humour is therefore used to deferentially package concerns (potentially problematic humour) or affiliate (potentially non-problematic humour). This paper reviews the good patient persona (compliance, sycophancy), potentially problematic humour (self-disparaging, gallows) and briefly, non-problematic humour (incongruity). The middle-range theory differentiates potentially problematic humour from non-problematic humour and notes that how humour is identified and addressed is central to whether patients concerns are resolved or not. The study provides a robust review of humour in healthcare interactions with important implications for practice. Further, this study develops and extends humour research and contributes to an evolved application of constructivist grounded theory.

Problematic cell phone use has alarmingly increased in industrialized countries in the past 10 years. For many perpetrators, it can turn into a behavioural addiction, although this is not a recognized medical condition. Although there are many tools for evaluating this use, one of the most widely used tools is the Mobile Phone Problematic Use Scale (MPPUS), which we test on a representative sample of the population in Spain to obtain an estimate of the prevalence of problematic cell phone use in our midst. The age range consists of 16-65 years, with 1,126 surveys conducted. In this population, we verify that the reliability and internal consistency of the MPPUS (α = 0.939) are maintained. Additionally, the construct validity, considering the derived factors (Abuse and Dependence, Craving and Loss of Control, and Dependence on the Social Environment) are aligned with other research and with diverse external criteria of addiction. We establish four categories of users (Casual, Regular, At Risk, and Problematic) and obtain a prevalence of 15.4% among At Risk Users and 5.1% among Problematic Users. This finding implies a total of 20.5% of Users with Problems. A binary logistic regression analysis shows that age, gender, level of education, and daily cell phone use predict problematic cell phone use. The results, based on multiple criteria, show that such problematic use shares features of recognized addictions, affecting large segments of the population and not only adolescents.

Problematic internet use in gamblers: impact on clinical and cognitive measures.

2017-12-01

Gambling is a commonplace phenomenon, existing along a continuum from occasional gambling to functionally impairing gambling disorder. The internet may act as a conduit for some gambling behaviors. The impact of problematic internet use on clinical and cognitive features relevant to gambling has received little research attention. A total of 206 adults aged 18-30 years who gamble at least five times per year were recruited from the general community and undertook detailed clinical and cognitive assessments. Problematic internet use was defined using a total score of 5 or more on Young's Diagnostic Questionnaire (YDQ). Linear regression was employed to evaluate the relative contribution of addictive-related, impulsive-related, and compulsive-related measures in predicting YDQ total scores in gamblers. Gamblers with problematic internet use (18% of the sample) reported lower quality of life, lower self-esteem, elevated rates of intermittent explosive disorder, gambling disorder symptoms, attention deficit hyperactivity disorder (ADHD) symptoms, antisocial personality disorder, and posttraumatic stress disorder (PTSD), as well as relative deficits in decision making and spatial working memory. In linear regression, the extent of problematic internet use was most significantly associated with increased gambling disorder symptoms and increased ADHD symptoms. Problematic internet use in gamblers is associated with worse quality of life, more problem/pathological gambling symptoms, more psychiatric morbidities, and select cognitive impairment. Refinement of the definition of problematic internet use and exploration of its clinical and cognitive associations are likely to be highly relevant to the treatment of problematic gambling.

Describe the uses of Internet and video games and quantify associated problematic uses. Information on student practices concerning the use of the Internet and video games was collected with a self-administered questionnaire. Problematic uses were identified with specific tools (Young criteria and Tejeiro criteria) and with self-evaluative questions. Information on life events with traumatic potential and use of psychoactive substances was also collected. Logistic regression models were applied to identify possible associated factors. Based on a sample of 1119 subjects, this study showed that students in Reunion Island are very concerned by the uses of the Internet and video games (98% and 46% of respondents). The prevalence of problematic use of the Internet accounted for 6% of respondents. Problematic uses of video games involved 8% of students (18% of gamers). Young people seemed unaware of their problematic practices and were seeking informations. The public respondent was also characterized by vulnerable situations (traumatic events induring their lives, consumption of psychoactive substances). Significant associations (with no identified causality) were examined, in particular between problematic uses of Internet and video games, and life events with traumatic potential. These first estimates of the prevalence of problematic use of Internet and video games on Reunion Island are important to promote locally collective awareness about these modern addictions. These results will be used to guide local actions of prevention and care, especially among younger generations. But it is necessary to conduct further work to better identify the factors associated with these problematic uses (determinants, comorbidities addictive…). Copyright © 2013.

Undergraduate students (n = 211) in an industrial/organizational psychology course completed the OCS, along with measures of procrastination, rejection sensitivity, loneliness, depression, and impulsivity. A confirmatory factor analysis indicated that problematic Internet use consists of four dimensions: diminished impulse control, loneliness/depression, social comfort, and distraction. As hypothesized, the OCS predicted all of the study variables in the expected directions. Representing a departure from previous research in this area, the current article focused on procrastination, impulsivity, and social rejection as key elements of problematic Internet use. Furthermore, interactive applications (e.g., chat) were most related to problematic Internet use, and scores on the OCS predicted being reprimanded at school or work for inappropriate Internet use. As a result, the utility of the OCS for both clinical assessment of Internet addiction and as an organizational preemployment screening measure to identify potential employees who are likely to abuse the Internet in the workplace (also known as "cyberslacking") were discussed.

Previous work at Aabo Akademi University has focused on identification and quantification of various sintering mechanisms which are relevant for problematic ash behavior during biomass combustion in fluidized bed combustion conditions, and on multi-component multi-phase thermodynamic phase equilibrium calculations of ash chemistry in these conditions. In both areas new information has been developed and useful modeling capabilities have been created. Based on the previous work, the authors now present a novel approach of using a combination of an advanced fuel analysis method and thermodynamic phase equilibrium calculations to predict the chemical and thermal behavior of the ash when firing biomass.more » Four different fuels [coal, forest residues, wood chips, and a mixture of forest residue and wood chips] were analyzed using the chemical fractionation analysis technique. Based on the results from these analyses, the authors formed two different ash fractions, (1) one fine sized fraction consisting of those elements found in the water and weak acid leach, and (2) a coarse ash particle fraction consisting of those elements found in the strong acid leach and non-leachable rest. The small sized ash fraction was then assumed to be carried up with the flue gases and consequently formed the base for any ash related problems in the flue gas channel. This fraction was therefore analyzed on its chemical and thermal behavior using multi-component multi-phase equilibrium calculations, by which the composition and the melting behavior was estimated as a function of the temperature. The amount of melt, which has earlier been found to be strongly related to problematic ash behavior, was finally expressed as a function of the temperature for the fraction. The coarse fraction was treated separately. Here the authors estimate the composition only. The paper discusses the results and their relevance to full scale combustion.« less

Occupational health and safety of merchant seafarers from Kiribati and Tuvalu.

2011-01-01

Intensifying international competition in the shipping industry in response to global pressures makes seafarers' jobs increasingly difficult. Challenging conditions in ship employment are problematic, particularly in a development context where home communities' dependence on seafarers' income is high and social protection is low. Qualitative fieldwork revealed that seafarers from Kiribati and Tuvalu endure exceptionally lengthy work periods at sea to remain competitive. Absence from home while working in constrained and mobile spaces with multinational crews, frequent security controls and speedy turnarounds impacting on sleep deprivation and decreased shore time have implications for physical and emotional health and can become safety matters. Hence, there is a growing need to address mechanisms to protect seafarers from the physical and emotional effects of global demands in the shipping industry.

The aim of the study was to examine the efficacy of an unguided, self-help cognitive behavior therapy (SH-CBT) booklet on hot flush and night sweat (HFNS) problem rating, delivered in a work setting. Women aged 45 to 60 years, having 10 or more problematic HFNS a week, were recruited to a multicenter randomized controlled trial, via the occupational health/human resources departments of eight organizations. Participants were 1:1 randomized to SH-CBT or no treatment waitlist control (NTWC). The primary outcome was HFNS problem rating; secondary outcomes included HFNS frequency, work and social adjustment, sleep, mood, beliefs and behaviors, and work-related variables (absence, performance, turnover intention, and work impairment due to presenteeism). Intention-to-treat analysis was used, and between-group differences estimated using linear mixed models. A total of 124 women were randomly allocated to SH-CBT (n = 60) and NTWC (n = 64). 104 (84%) were assessed for primary outcome at 6 weeks and 102 (82%) at 20 weeks. SH-CBT significantly reduced HFNS problem rating at 6 weeks (SH-CBT vs NTWC adjusted mean difference, -1.49; 95% CI, -2.11 to -0.86; P < 0.001) and at 20 weeks (-1.09; 95% CI, -1.87 to -0.31; P < 0.01). SH-CBT also significantly reduced HFNS frequency, improved work and social adjustment; sleep, menopause beliefs, HFNS beliefs/behaviors at 6 and 20 weeks; improved wellbeing and somatic symptoms and reduced work impairment due to menopause-related presenteeism at 20 weeks, compared with the NTWC. There was no difference between groups in other work-related outcomes. A brief, unguided SH-CBT booklet is a potentially effective management option for working women experiencing problematic HFNS.

A New "Shield of the Weak": Continued Paternalism of Domestic Violence Services in Uruguay.

Bloom, Allison

2018-03-01

Drawing on ethnographic and historical research, this article illuminates the limitations of the Uruguayan domestic violence services system. In spite of how advocates in Uruguay successfully used a human rights platform to secure legislation and services, this system now faces significant critique. Using Iris Marion Young's work on the "logic of masculinist protection" and historical parallels in Uruguay's welfare system, I discuss how a paternalistic approach may be to blame. I highlight how this paternalism contributes to the paternalism that problematically underlies gendered violence-reinforcing rather than addressing oppressive ideologies and structures that impede improving conditions for women.

The work of negotiating HIV as a chronic condition: a qualitative analysis.

PubMed

Thompson, Lee; Abel, Gillian

2016-12-01

Living with human immunodeficiency virus (HIV) in the industrialised world has for over a decade been conceptualised as living with a chronic illness. People living with HIV now are amongst the first to live and age with the virus. Drawing on a qualitative longitudinal study in a low-incidence area in a low-incidence country, this paper investigates the nuanced ways that people negotiate this condition. While it has been argued that HIV is a condition like any other chronic disease, our thematic analysis reveals some similarities and particularities around living with the condition. In comparing themselves to others with the condition, high levels of diversity of experience were identified that extended well beyond length of time from diagnosis. In comparing their illness with other illnesses, the location, for example, of their specialist service within a clinic for those with acute sexually transmitted diseases was identified as problematic. The work involved in maintaining a coherent sense of self in the face of existing and shifting challenges as a result of their infection was a second strong theme. The final theme involved flux and flex work in the ways people sought to gain and maintain control over various aspects of their lives. All of these experiences are mediated by place; that is the experience is not the same as that of those who live where there is a much higher incidence of infection. The work involved in negotiating this condition in low-incidence environments deserves more attention, but aspects of these findings are significant in higher incidence contexts as well; in particular, passivity in face of infection as one ages and the potential for medication refusal as a means of maintaining control over life and death.

The Influence of Women’s Neighborhood Resources on Perceptions of Social Disorder

PubMed Central

Jackson, Aubrey L.; Soller, Brian; Browning, Christopher R.

Research links neighborhood social disorder with poorer health. But factors beyond observed disorder may influence perceptions that social disorder is problematic. This study investigates whether women’s aggregate socioeconomic resources relative to men’s in the broader neighborhood context attenuate the extent to which more prevalent observed social disorder within the immediate residential neighborhood contributes to perceptions of more problematic social disorder. This attenuation likely is pronounced among women, for whom sexual harassment in public spaces is a more salient concern compared to men. Using data from the Project on Human Development in Chicago Neighborhoods, multilevel models analyze individual perceptions of problematic social disorder (N=3,107) regressed on the interactive effect of observed social disorder within the census block group (N=525) and women’s relative resources within the neighborhood cluster (N=80). The results show that women’s relative resources within the broader neighborhood context protect against women’s perceptions that typically undesirable neighborhood conditions are problematic.

The construction of ethnic differences in work incapacity risks: Analysing ordering practices of physicians in the Netherlands.

PubMed

Meershoek, Agnes; Krumeich, Anja; Vos, Rein

2011-01-01

Drawing from Science and Technology Studies we investigate the consequences for social differentiation of physicians' practices in Dutch illness certification. Using participant observation methods, we followed six 'Arbodienst' physicians for two weeks each. Our analysis explores whether and how the work of Dutch physicians contributes to the appearance of a category of 'problematic migrant patients'. We present how physicians, in using instruments to distinguish plausible from implausible claims for sick leave, impose order upon reality. In particular situations this ordering involves a distinction between Dutch and migrant clients. Here ethnicity appears in physicians' practice as a separate instrument to constitute order, which in the case of migrants overrules the productive instruments that are used for 'Dutch' clients. By interpreting clients' behaviour in cultural terms and making them into strangers, physicians lose their ability to fine-tune their coaching activities to the needs of these clients. As a result migrants remain work incapacitated for a longer period, which leads to a higher risk of their ending up in the disability pension program. As a consequence migrants become visible as a problematic group in the data on work incapacity and disability. The practice to categorise migrant clients with separate instruments thus results in a 'hard' category of problematic migrant clients and leads to social differentiation.

This is the first study to investigate how college students in the U.S. with problematic Internet use perceive the role the Internet plays within their families of origin. The sample included 27 U.S. university students who self-identified as excessive Internet users. Participants reported spending more than 25 hours a week on the Internet on non-school or non-work-related activities and reported Internet-associated health and/or psychosocial problems. This study provides descriptive statistics from participants' completion of two problematic Internet use measures (i.e., Young's Diagnostic Questionnaire and the Compulsive Internet Use Scale) and reports findings from four focus groups. Three themes emerged from the focus groups: (1) family connectedness, (2) family conflict/family disconnection, and (3) family Internet overuse. The findings of this study are a first step toward the design of effective interventions for problematic Internet use among U.S. college students and serve to inform clinical practice and health policy in this area.

Acceptance and Commitment Therapy for Problematic Internet Pornography Use: A Randomized Trial.

PubMed

Crosby, Jesse M; Twohig, Michael P

2016-05-01

Problematic Internet pornography use is the inability to control the use of pornography, the experience of negative cognitions or emotions regarding pornography use, and the resulting negative effects on quality of life or general functioning. This study compared a 12-session individual protocol of acceptance and commitment therapy (ACT) for problematic Internet pornography use to a waitlist control condition with 28 adult males, all but 1 of whom were members of the Church of Jesus Christ of Latter-day Saints. Measures of self-reported pornography viewing, standardized measures of compulsive sexual behavior and related cognitions, and quality of life occurred at pretreatment, posttreatment, and 3-month follow-up. Results demonstrate significant between-condition reductions in pornography viewing compared to the waitlist condition (93% reduction ACT vs. 21% waitlist). When combining all participants (N=26), a 92% reduction was seen at posttreatment and an 86% reduction at 3-month follow-up. Complete cessation was seen in 54% of participants at posttreatment and at least a 70% reduction was seen in 93% of participants. At the 3-month follow-up assessment, 35% of participants showed complete cessation, with 74% of participants showing at least 70% reduction in viewing. Treatment suggestions and future directions are discussed. Copyright © 2016. Published by Elsevier Ltd.

A Laboratory-Based Test of the Relation between Adolescent Alcohol Use and Panic-Relevant Responding

2015-01-01

A burgeoning literature supports a link between alcohol use and panic-spectrum problems (e.g., panic attacks, disorder) among adolescents, but the direction of influence has yet to be properly examined. From a theoretical perspective, panic-spectrum problems may increase risk for problematic drinking via affect regulation efforts (e.g., self-medication), and problematic consumption also may increase or initiate panic-relevant responding (e.g., learning or kindling models). The objective of the current investigation was to examine the role of prior alcohol use in predicting panic-relevant responding, as well as panic symptom history in predicting the desire to consume alcohol, in the context of either a voluntary hyperventilation or a low-arousal task. Participants were community-recruited adolescents aged 12-17 years (n = 92, Mage = 15.42, SD = 1.51; 39.1% girls). Results indicated that prior alcohol use predicted panic-relevant responding among those undergoing the hyperventilation task (but not the low-arousal task), and that this finding was robust to the inclusion of theoretically-relevant covariates (i.e. age, sex, negative affectivity). However, panic symptom history did not predict the desire to consume alcohol as a function of either the hyperventilation or low-arousal condition. This work sheds further light on the nature of the relation between panic-spectrum problems and problematic alcohol use in adolescence. Specifically, the current findings suggest that frequent alcohol use may increase panic vulnerability among adolescents, whereas acute panic symptoms may not elicit the immediate (self-reported) desire to drink.

‘Recovery work’ and ‘magic’ among long-term mental health service-users

PubMed Central

Laws, Jennifer

2013-01-01

Based on an extended period of qualitative research with mental health service-users in north-east England, this article considers the various forms of ‘magical work’ and ‘recovery work’ that emerge in the lives of people living with severe mental health problems. Given the now sizeable body of literature which seeks to problematize traditional conceptual boundaries of work, the article asks to what extent these hidden and unusual work-forms might also be considered legitimate members of the category. Rather than argue for the expansion of the construct to accommodate these activities, the paper attempts simply to problematize the extent to which so-called ‘mad’ forms of work are irresolvably different to more conventional forms of occupation. In challenging notions of the psychiatric patient as inevitably inactive, new vocabularies for service-user work are explored. Concluding remarks are also directed to recent policy debates concerning ‘back-to-work’ welfare reform for long-term out of work service-users. PMID:24223439

This paper is oriented to study techniques to improve the precision of the systems for wear measurement of contact wire in the railways. The problematic of wear measurement characterized by some important determining factors like rate of sampling and auscultation conditions is studied in detail. The different solutions to resolve the problematic successfully are examined. Issues related to image acquisition and image processing are discussed. Type of illumination and sensors employed, image processing hardware and image processing algorithms are some topics studied. Once analyzed each one factor which have influence on the precision of the measurement system, there are proposed an assembly of solutions that allow to optimize the conditions under which the inspection can be carried out.

The role of urgency and its underlying psychological mechanisms in problematic behaviours.

The urgency facet of impulsivity, that is, the tendency to act rashly in response to intense emotional contexts [Cyders, M. A., & Smith, G. T. (2008). Emotion-based dispositions to rash action: positive and negative urgency. Psychological Bulletin, 134, 807-828], has been related to a wide range of maladaptive behaviours. The present study further investigates the role of urgency in problematic behaviours by considering distinct psychological mechanisms that may underlie this component of impulsivity. With this aim, 95 volunteer participants were screened with self-reported questionnaires assessing urgency and three problematic behaviours (compulsive buying, excessive mobile phone use, excessive Internet use). They performed two laboratory tasks: a stop-signal task designed to assess the capacity to inhibit prepotent responses in response to both neutral and emotional stimuli; and the Iowa Gambling Task (IGT) measuring the ability to take into account the future consequences of an action. A poor ability to inhibit prepotent responses in the emotional condition of the stop-signal task was found to predict more disadvantageous choices in the IGT, which ultimately results in higher urgency and more problematic behaviours. These findings shed new light on the construct of urgency, its related psychological mechanisms, and its role in problematic behaviours. Copyright © 2010 Elsevier Ltd. All rights reserved.

Using hydrofluoric acid for morphological investigations of Zoanthids (Cnidaria: Anthozoa): a critical assessment of methodology and necessity.

PubMed

Reimer, James Davis; Nakachi, Shu; Hirose, Mamiko; Hirose, Euichi; Hashiguchi, Shinji

2010-10-01

Zoanthids comprise an order of benthic, generally colonial cnidarians, which can usually be distinguished from other hexacorallians by embedded sand and detritus in their mesoglea to help strengthen their structure. These animals are becoming increasingly important research subjects in biochemistry and other research fields. Their inclusion of both calcium and silica results in the need for both decalcification and desilification for internal morphological examinations. Since the methodology of hydrofluoric acid (HF) desilification has rarely been documented in zoanthids, histological surveys for zoanthid taxonomy have often been abandoned and their taxonomy is often problematic. Recent investigations utilizing molecular methods have brought a clearer understanding of zoanthid diversity, but standardization of HF treatments are still needed to provide a link between molecular and more traditional techniques, and to properly examine specimens for which molecular methods may not be an option (e.g., formalin-preserved specimens, etc.). Here, we use both "straight" HF and, for the first time with zoanthids, buffered HF (BHF) treatments at different treatment lengths (1-48 h) on polyps from three different species of zoanthids for histological examination. Section conditions were judged based on the presence/absence of embedded detritus, drag marks, and tissue condition. Results show that the BHF treatment resulted in slightly better tissue conditions for all specimens, and suggest that desilification works well regardless of treatment time for species with smaller (polyp diameter <0.5 cm), less heavily encrusted polyps. Desilification of heavily encrusted Palythoa mutuki polyps were still problematic, with at least 24 h treatment needed. To aid future research, we provide guidelines for HF treatments of zoanthid specimens.

Ethically problematic treatment decisions: a physician survey.

Experiencing ethical problems requires both ethically problematic situations and ethical sensitivity. Ethically problematic treatment decisions are distressing and might reflect health care quality problems. Whether all physicians actually experience ethical problems, what these problems are and how they vary according to physician age, gender and work sector are largely unknown. A mail survey of all non-retired physicians licensed in Finland (n = 17,172, response rate 75.6%). The proportion of physicians reporting having made ethically problematic treatment decisions decreased in linear fashion from 60% at ages below 30 years to 21% at ages over 63 years. The only problem that did not decrease in frequency with age was having withdrawn necessary treatments. Women and primary care physicians reported problematic decisions most often, although gender differences were small. Primary care physicians most often reported having performed too many investigations or having pressured patients, whereas hospital physicians emphasized having withdrawn necessary treatments. Performing unnecessary treatments or investigations was explained by pressure from patients or relatives, and performing too few treatments or investigations was explained by inadequate resources. In general, young physicians felt pressured to do too much, whereas older physicians felt they could not do enough due to inadequate resources. Older physicians might be less exposed to ethically problematic situations, be more able to handle them or have lower ethical sensitivity. Young physicians could benefit from support in resisting pressure to perform unnecessary treatments, whereas older physicians might benefit from training in recognizing ethical issues.

Phantom bite: a real or a phantom diagnosis? A case report.

This case report describes computer-guided occlusal therapy in a patient who met the unified diagnostic criteria for phantom bite. After a review of the patient's medical history, along with a diagnostic work-up that included cone beam computed tomography, temporomandibular joint vibration analysis, and digital occlusal analysis, problematic dental components were discovered (including prolonged disclusion time and imbalanced bite force). A digital occlusal analyzer evaluated the patient's occlusion and systematically guided the necessary changes. After reduction of the disclusion time and correction of the occlusal force imbalance, the patient reported significant improvement in comfort. The results suggest that phantom bite could be an abnormal occlusal condition and not a psychological or neurologic somatoform disorder.

Background and aims Problematic Internet game use is an important social issue that increases social expenditures for both individuals and nations. This study identified predictors and patterns of problematic Internet game use. Methods Data were collected from online surveys between November 26 and December 26, 2014. We identified 3,881 Internet game users from a total of 5,003 respondents. A total of 511 participants were assigned to the problematic Internet game user group according to the Diagnostic and Statistical Manual of Mental Disorders Internet gaming disorder criteria. From the remaining 3,370 participants, we used propensity score matching to develop a normal comparison group of 511 participants. In all, 1,022 participants were analyzed using the chi-square automatic interaction detector (CHAID) algorithm. Results According to the CHAID algorithm, six important predictors were found: gaming costs (50%), average weekday gaming time (23%), offline Internet gaming community meeting attendance (13%), average weekend and holiday gaming time (7%), marital status (4%), and self-perceptions of addiction to Internet game use (3%). In addition, three patterns out of six classification rules were explored: cost-consuming, socializing, and solitary gamers. Conclusion This study provides direction for future work on the screening of problematic Internet game use in adults. PMID:27499227

This paper reports results from a preliminary observational study of ayahuasca-assisted treatment for problematic substance use and stress delivered in a rural First Nations community in British Columbia, Canada. The "Working with Addiction and Stress" retreats combined four days of group counselling with two expert-led ayahuasca ceremonies. This study collected pre-treatment and six months follow-up data from 12 participants on several psychological and behavioral factors related to problematic substance use, and qualitative data assessing the personal experiences of the participants six months after the retreat. Statistically significant (p < 0.05) improvements were demonstrated for scales assessing hopefulness, empowerment, mindfulness, and quality of life meaning and outlook subscales. Self-reported alcohol, tobacco and cocaine use declined, although cannabis and opiate use did not; reported reductions in problematic cocaine use were statistically significant. All study participants reported positive and lasting changes from participating in the retreats. This form of ayahuasca-assisted therapy appears to be associated with statistically significant improvements in several factors related to problematic substance use among a rural aboriginal population. These findings suggest participants may have experienced positive psychological and behavioral changes in response to this therapeutic approach, and that more rigorous research of ayahuasca-assisted therapy for problematic substance use is warranted.

Estimating abundance of Antarctic minke whales is central to the International Whaling Commission's conservation and management work and understanding impacts of climate change on polar marine ecosystems. Detecting abundance trends is problematic, in part because minke whales are frequently sighted within Antarctic sea ice where navigational safety concerns prevent ships from surveying. Using icebreaker-supported helicopters, we conducted aerial surveys across a gradient of ice conditions to estimate minke whale density in the Weddell Sea. The surveys revealed substantial numbers of whales inside the sea ice. The Antarctic summer sea ice is undergoing rapid regional change in annual extent, distribution, and length of ice-covered season. These trends, along with substantial interannual variability in ice conditions, affect the proportion of whales available to be counted by traditional shipboard surveys. The strong association between whales and the dynamic, changing sea ice requires reexamination of the power to detect trends in whale abundance or predict ecosystem responses to climate change.

Eliciting, understanding, and honoring patients’ values— the things most important to them in daily life—is a cornerstone of patient-centered care. However, this rarely occurs explicitly as a routine part of clinical practice. This is particularly problematic for individuals with multiple chronic conditions (MCC) because they face difficult choices about how to balance competing demands for self-care in accordance with their values. In this study, we sought to inform the design of interventions to support conversations about patient values between patients with MCC and their health care providers. We conducted a field study that included observations of 21 clinic visits for patients who have MCC, and interviews with 16 care team members involved in those visits. This paper contributes a practice-based account of ways in which providers engage with patient values, and discusses how future work in interactive systems design might extend and enrich these engagements.

Electromagnetic scattering by impedance structures

NASA Technical Reports Server (NTRS)

Balanis, Constantine A.; Griesser, Timothy

1987-01-01

The scattering of electromagnetic waves from impedance structures is investigated, and current work on antenna pattern calculation is presented. A general algorithm for determining radiation patterns from antennas mounted near or on polygonal plates is presented. These plates are assumed to be of a material which satisfies the Leontovich (or surface impedance) boundary condition. Calculated patterns including reflection and diffraction terms are presented for numerious geometries, and refinements are included for antennas mounted directly on impedance surfaces. For the case of a monopole mounted on a surface impedance ground plane, computed patterns are compared with experimental measurements. This work in antenna pattern prediction forms the basis of understanding of the complex scattering mechanisms from impedance surfaces. It provides the foundation for the analysis of backscattering patterns which, in general, are more problematic than calculation of antenna patterns. Further proposed study of related topics, including surface waves, corner diffractions, and multiple diffractions, is outlined.

This study investigated physical work environment conditions and sought to identify risk factors in terms of main potential hazards, exposure to physical strain, and the 12-month prevalence of musculoskeletal disorders (MSD) through two postal surveys of Swedish farmers rearing red veal calves (8 to 11 months slaughter age) during April-June 2008 and young bulls (12 to 24 months slaughter age) during March-May 2009. Among 155 red veal producers, the response rate was 45% (n = 59), while among 241 young bull producers finishing 100 or more bulls per year the response rate was 42% (n = 101). A questionnaire was used to obtain general facts about the farm, work time, and frequency of predefined daily and non-daily work tasks. Perceived physical exertion in relation to each work task was assessed by the farmers using the Borg CR-10 scale and further analyzed according to duration and repetitiveness in a physical work strain (PWS) index. The average physical work strain during the predefined work tasks in red veal and young bull finishing was estimated at 3 (moderate strain) on the CR-10 scale. Up to 42% of the surveyed farmers experienced stress and worry about beef production and high levels of potential hazards. High daily work pace and an uncomfortable work climate were other problematic factors. Highly repetitive tasks and physically demanding animal handling were risk factors that increased PWS significantly The 12-month prevalence of MSD was 51% among red veal producers and 65% among young bull producers. Work-related injuries were reported by 20% and 39% of respondents on red veal and young bull farms, respectively, of which 96% and 89% of the cases were related to working with animals.

Research documents increased and problematic alcohol use during study abroad experiences for college students yet no research documents effective preventive programs with these students. The present randomized controlled trial was designed to prevent increased and problematic alcohol use abroad by correcting misperceptions of peer drinking norms abroad and by promoting positive and healthy adjustment into the host culture (i.e., sojourner adjustment) through brief online personalized feedback interventions. A sample of 343 study abroad college students was randomly assigned to one of four conditions including a personalized normative feedback intervention (PNF), a sojourner adjustment feedback intervention (SAF), a combined PNF + SAF intervention, and an assessment-only control condition. Generalized estimated equation analyses accounting for baseline drinking and consequences revealed an intervention effect for PNF that was mitigated by baseline drinking level, such that PNF was best for those with lighter baseline drinking, but heavier baseline drinkers receiving PNF alone or PNF + SAF drank comparatively similar or more heavily abroad to those in the control condition. However, PNF + SAF condition participants with greater baseline levels of consequences reported comparatively less consequences abroad than their control participants. Thus, PNF alone may be helpful for lighter drinkers at predeparture and the addition of SAF to PNF may help prevent consequences abroad for those reporting more consequences prior to departure abroad. This research represents an important first step in designing and implementing efficacious interventions with at-risk study abroad college students, for which no current empirically-based programs exist.

Should Psychosocial Safety Climate Theory Be Extended to Include Climate Strength?

Psychosocial safety climate (PSC; climate for psychological health) is an organizational antecedent to work conditions articulated in the job demands-resources model. We responded to calls for broader consideration of organizational climate in terms of both climate level and strength. We tested PSC level and strength as main and interactive predictors of work conditions, psychological health, and engagement. Using multilevel analysis and cross-sectional data, the effects of unit-level PSC constructs were investigated in 21 hospital work units (n = 249 employees) in Australia. The correlation between PSC levels (measured at the unit mean) and PSC strength (measured as unit -1 × SD) was moderate and positive, suggesting that ceiling effects of PSC scores were not problematic. PSC level was a better predictor than PSC strength or their interactions for job demands (psychological and emotional demands), job resources (e.g., skill discretion and organizational support), and health (emotional exhaustion). For engagement, the interaction was significant-improving engagement, therefore, benefits from high levels of PSC and PSC strength within the work units. So, in answer to the research question regarding PSC theory extension, "it depends on the outcome." Research limitations are acknowledged, and the potential of the PSC model to guide the reduction of workplace psychosocial risk factors and the negative consequences is discussed.

What is healthy work for women and men? - A case-control study of gender- and sector-specific effects of psycho-social working conditions on long-term sickness absence.

PubMed

Lidwall, Ulrik; Marklund, Staffan

2006-01-01

The aim of the study was to investigate the relevance of the demand-control model and social support in predicting long-term sickness absence (LTSA). Identifying gender- and sector- (private vs. public) specific patterns was in focus. The study uses a cross-sectional design with a case and a control group. The cases are a sample of 2 327 long-term sick listed (>60 days) and the controls are a Swedish population-based sample of 2 063. Data on sickness absence were retrieved from the Swedish national social insurance registers. Data on health, working and living conditions were gathered through a self-administered questionnaire. The results show that employed women have a notably higher risk for LTSA than employed men. High-strain jobs increase the odds for LTSA among both women and men. Active jobs were also associated with LTSA among women. The study confirms the demand-control model (job strain hypothesis) and social support and their associations with LTSA. However, the job strain hypothesis is more evident in the private sector. Active jobs with high psychological demands and high decision latitude seem to be problematic for many women, especially in the private sector. Thus, the active learning hypothesis receives no support for women in the Swedish working population in general.

Provision of mental health services to correctional populations places considerable demands on clinical staff to provide efficient and effective means to screen patients for severe mental disorders and other emergent conditions that necessitate immediate interventions. Among the highly problematic behaviors found in correctional settings are forms of acting out (e.g., suicide and aggression towards others) and response style (e.g., motivations to malinger). The current study examined the usefulness of the Personality Assessment Inventory (PAI) in assessing problematic behaviors in a corrections-based psychiatric hospital. As evidence of criterion related validity, selected PAI scales were compared to (a) evidence of malingering on the Structured Interview of Reported Symptoms (SIRS), (b) suicidal threats and gestures, and (c) ratings of aggression on the Overt Aggression Scale (OAS). In general, results supported the use of the PAI for the assessment of these problematic behaviors.

1977-10-21

The most important change in the qualification regulations in force at the present time is the provision for the practical training of medical students, which occurs not only in university hospitals but also in "teaching hospitals" outside the university. The realization of the practical year is problematic according to the actual conditions because of the difficulties and financial investment necessarily associated with it. Furthermore, the legal status of the students during the practical activities differes from that of earlier medical assistants, because according to the present law the legal provisions for employment and social insurance such as the determination of division of labour, working hours and remuneration and also for third party and accident insurance do not apply.

The politics of corruption, inequality, and the socially excluded.

PubMed

Santos Salas, Anna

2013-07-01

In this article, the production of knowledge in the context of socially excluded people exposed to inequality, oppression, and exploitation is problematized. The analysis follows Enrique Dussel's philosophical exegesis of the politics of power and corruption and his vision of a critical transformation of the social political order. The argument is also informed by the work of critical educator Paulo Freire, who elucidates the conditions of oppression and marginalization and highlights the importance of conscientization to develop a critical awareness of these conditions. Hannah Arendt's work on the politics of understanding totalitarianism also assists in the elucidation of the machinery that operates behind oppression to sustain power and inequality. The article emphasizes the need to recognize the inequality of conditions that exists between the producer of knowledge and those who live through inequality and oppression in their lived corporality. A critical transformation of the process of production of knowledge is needed to both acknowledge the conditions that sustain this endeavour in the first place and avoid the corruption of knowledge. A work of conscientization is also necessary among knowledge producers to undertake a critical analysis of inequality that exposes the corruption of power. This analysis needs to examine and unmask the hidden mechanisms that perpetuate inequality and oppression and serve only the interests of a few. The abysmal gaps between the wealthy and the poor within and among countries bespeak a degree of human indifference that reflects a most serious and complex phenomenon that perverts something profoundly human in our societies. © 2013 John Wiley & Sons Ltd.

Problematic computer game use among adolescents, younger and older adults.

Playing digital games has been associated with forms of addictive behavior. Past research on the subject has often been criticized on theoretical and empirical grounds, due mainly to measurement or sampling issues. The present study aims to overcome these two limitations, and presents data from a representative study in Germany using an already established instrument for measuring problematic game use. Large-scale, representative study using a computer-assisted telephone survey. Germany. A total of 580 adolescents between 14 and 18 years of age, 1866 younger adults between 19-39 years and 1936 older adults aged 40 years and older (overall n = 4382). Problematic game use was measured with the Gaming Addiction Short Scale (GAS), which covers seven criteria including salience, withdrawal and conflicts. Additionally, differential aspects of personality, as well as gaming behaviour, were measured. Only seven respondents [0.2%, 95% confidence interval (CI): 0.1, 0.3] met all criteria of the GAS Scale. In contrast, 3.7% (95% CI: 3.1, 4.3) of the respondents can be considered problematic users, meeting at least half these conditions. The percentage of problematic gamers among adolescents is above average (7.6%, 95% CI: 5.6, 10.1). High GAS scores are associated with aggression, low sociability and self-efficacy and lower satisfaction with life. Additionally, these scores correspond with intensive use and preferences for certain gaming genres across all age groups. Following Gaming Addiction Short Scale criteria, gaming addiction is currently not a widespread phenomenon among adolescents and adults in Germany. Gaming Addiction Short Scale scores are associated with intensive use, as well as certain problematic aspects of individuals' personalities and social lives. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

To prevent a future shortage of cardiologists, it is important for female cardiologists to continue working. Gender differences in the professional and private lives of cardiologists, as well as the barriers to work for female cardiologists, were surveyed. In August 2007, a questionnaire was mailed to all 195 faculty members/fellows and 155 alumni of the Department of Cardiovascular Medicine at Nippon Medical School. More female cardiologists were dissatisfied with their job than male cardiologists (34% vs 17%, P<0.005). Women reported greater career limitation by family responsibilities and housework. Men and women both reported that long working hours was the most problematic issue, but significantly more women reported this than men (76% vs 94%, P<0.05). Female cardiologists were more concerned about occupational radiation exposure (88% vs 59%, P<0.01) and wanted opportunities for retraining after childcare leave (100% vs 76%, P<0.01). The following measures should be taken: (1)establishment of more family-friendly working conditions in hospitals, (2)provision of various work positions that allow more flexibility and predictability for women, (3)establishment of a retraining system, and (4)development of work and research opportunities that are attractive to women. The Japanese Circulation Society is expected to establish a retraining system at certified institutions.

Introduction Medical cannabis is increasingly being used for a variety of health conditions as more states implement legislation permitting medical use of cannabis. Little is known about medical cannabis use patterns and motives among adults across the lifespan. Methods The present study examined data collected at a medical cannabis dispensary in San Francisco, California. Participants included 217 medical cannabis patients who were grouped into age-defined cohorts (younger: 18–30, middle-aged: 31–50, and older: 51–72). The age groups were compared on several measures of cannabis use, motives and medical conditions using one-way ANOVAs, chi-square tests and linear regression analyses. Results All three age groups had similar frequency of cannabis use over the past month; however, the quantity of cannabis used and rates of problematic cannabis use were higher among younger users relative to middle-aged and older adults. The association between age and problematic cannabis use was moderated by age of regular use initiation such that earlier age of regular cannabis use onset was associated with more problematic use in the younger users, but not among older users. Middle-aged adults were more likely to report using medical cannabis for insomnia, while older adults were more likely to use medical cannabis for chronic medical problems such as cancer, glaucoma and HIV/AIDS. Younger participants reported cannabis use when bored at a greater rate than middle-aged and older adults. Conclusions Findings suggest that there is an age-related risk for problematic cannabis use among medical cannabis users, such that younger users should be monitored for cannabis use patterns that may lead to deleterious consequences.

2015-01-01

Problematic Internet use (PIU) is an emerging health concern that lacks screening measures validated for use with adolescents and young adults. This study aimed to validate the Problematic and Risky Internet Use Screening Scale (PRIUSS) for use with older adolescents and to increase its clinical utility by determining scoring guidelines and assessing the relationship between PIU and other mental health conditions. This cross-sectional survey study took place at a large, public Midwestern university among 330 older adolescents aged 18 to 25 years. Confirmatory factor analysis and Spearman's correlations were used to assess the PRIUSS' structural and construct validity, respectively. A risk-based scoring cutoff was estimated using a Bayesian latent class modeling approach to computing a receiver operating characteristic curve. The confirmatory factor analysis indices for the 3-factor model indicated an acceptable fit (goodness-of-fit index 0.89, root mean square error of approximation 0.07). A cutoff of 25 (sensitivity 0.80, 95% confidence interval [CI] 0.47-0.99; specificity 0.79, 95% CI 0.73-0.84) is proposed for identifying those at risk for PIU. Participants at risk for PIU were at significantly greater odds of also reporting symptoms of attention-deficit/hyperactivity disorder (odds ratio [OR] 2.36 95% CI 1.21-4.62, P = .009), depression (OR 3.25, 95% CI 1.65-6.42, P = .008), and social anxiety (OR 3.77, 95% CI 2.06-6.89, P < .000). The PRIUSS demonstrated validity as a PIU screening instrument for adolescents and young adults. Screening for PIU may also help to identify those at high reciprocal risk for other mental health conditions. Copyright © 2015. Published by Elsevier Inc.

2016-12-01

Debates about how knowledge is made and valued in evidence-based medicine (EBM) have yet to understand what discursive, social, and historical conditions allowed the EBM approach to stabilize and proliferate across western medical education. This paper uses a genealogical approach to examine the epistemological tensions that emerged as a result of various problematizations of uncertainty in medical practice. I explain how the problematization of uncertainty in the literature and the contingency of specific social, political, economic, and historical relations allowed the EBM approach to become a programmatic and pedagogical focus of the Faculty of Medicine at McMaster University and beyond.

[Significance of scores in intensive care medicine].

PubMed

Hainich, R; Rabe, H

2012-02-01

For nurses in intensive care units (ICUs), the use of scoring instruments is a familiar and important part of their work. Frequently, condition-referred instruments are used to assess various conditions, e.g., pain intensity or degree of alertness. Furthermore, ICU nurses use instruments to assess the risk, e.g., of developing pressure ulcers or to fall. A third important group of instruments are those used to document resource utilization by nurses. However, the estimation of the overall benefit of such scores in the intensive care setting is problematic. In Germany, assessment instruments are mainly required for use within the range of the SGB XI. With regard to intensive care settings, the majority of publications address the presentation of scores or the development of new instruments. From the nursing perspective, no clear conceptual distinction can be made between scores and scales; many instruments lack scientific proof of their benefit for nursing care. Discrepancies with the physicians' viewpoint may exist in some cases.

Training yourself while training students: the constant challenge of vocational training teachers.

PubMed

Chatigny, Céline; Lévesque, Sophie; Riel, Jessica

2012-01-01

This study characterized teachers' work at a vocational training (VT) center and the conditions under which the activity is learned. We interviewed administrators and 12 teachers (4 males, 8 females) representing three study programs, selected as representative (age, seniority, and employment status). What emerged was a portrait of an evolving profession within an organization that was highly structured in terms of the assignment of tasks and schedules, but unstructured in terms of support for job adaptation and job retention. The major challenges for the teachers were to integrate their trade-specific knowledge with the new skills required to teach the trade, and to find time for class preparation. The lack of resources and support caused dissatisfaction, stress, problematic work-study-family balance, and health problems, particularly among new teachers. A passion for teaching seems to compensate partly for these difficulties but it is uncertain for how long. Further research is necessary in order to understand the coping strategies employed by vocational training teachers. The findings of this study offer guidance for the development of resources that can assist with learning and performing the work of a VT teacher, and for a better recognition of the work of VT teachers.

Background and aims Excessive use of video games among children and adolescents is a growing concern. The aim of this study was to investigate the effectiveness of a brief parental guide with advices and strategies for regulating video gaming in children. Methods A random sample of guardians of children between the age of 8-12 years old (N = 5,864) was drawn from the Norwegian Population Registry and equally randomized into an intervention and a control condition. A parental guide based on clinical and research literature was distributed by postal mail to those in the intervention condition. A 4-month follow-up survey comprising questions about problematic video gaming, gaming behavior, sleep activity, and parental video game regulation behavior was administered. Results Independent t-tests revealed no significant differences between the two conditions (N = 1,657, response rate 30.1%) on any outcome measure. An ANOVA with planned comparisons showed that respondents who reported that they had read and followed the parental guide reported more video game problems and used more parental mediation strategies than those who did not read and follow the guide. Conclusions We found no evidence for the effectiveness of the psychoeducational parental guide on preventing problematic video gaming in children. However, the guide was read and positively assessed by a significant proportion of guardians. Differences between those who studied the guide and those who did not may indicate that parental guides are better aimed at providing important information to those who already have problems rather than as a mean of primary prevention.

The nowadays classical Anthropic Principle is put both in the historical perspective of the traditional problem of "the place of man in the Universe', and in the confluence of several scientific "border" issues, some of which, due to their problematical nature, are also subject of philosophical analysis. On the one hand, the scientific uses of the Principle, related to the initial and constitutional conditions of "our Universe", are enumerated, as they are supposedly necessary for the appearance and consequent development of Life--up to Man--. On the other, an organized collection of the principles of today's Physics is synthetically exhibited. The object of this work is to determine the intrinsic scientific nature of the Anthropic Principle, and the role it plays in the global frame of the principles of Physics (Astrophysics, Astrobiology and Cosmology).

Effects of environmental noise on cognitive (dys)functions in schizophrenia: A pilot within-subjects experimental study

Wright, Bernice; Peters, Emmanuelle; Ettinger, Ulrich; Kuipers, Elizabeth; Kumari, Veena

Cognitive impairment, particularly in attention, memory and executive function domains, is commonly present and associated with poor functional outcomes in schizophrenia. In healthy adults, environmental noise adversely affects many cognitive domains, including those known to be compromised in schizophrenia. This pilot study examined whether environmental noise causes further cognitive deterioration in a small sample of people with schizophrenia. Eighteen outpatients with schizophrenia on stable doses of antipsychotics and 18 age and sex-matched healthy participants were assessed on a comprehensive cognitive battery including measures of psychomotor speed, attention, executive functioning, working memory, and verbal learning and memory under three different conditions [quiet: ~ 30 dB(A); urban noise: building site noise, 68–78 dB(A); and social noise: background babble and footsteps from a crowded hall without any discernible words, 68–78 dB(A)], 7–14 days apart, with counter-balanced presentation of noise conditions across participants of both groups. The results showed widespread cognitive impairment in patients under all conditions, and noise-induced impairments of equal magnitude on specific cognitive functions in both groups. Both patient and healthy participant groups showed significant disruption of delayed verbal recall and recognition by urban and social noise, and of working memory by social noise, relative to the quiet condition. Performance under urban and social noise did not differ significantly from each other for any cognitive measure in either group. We conclude that noise has adverse effects on the verbal and working memory domains in schizophrenia patients and healthy participants. This may be particularly problematic for patients as it worsens their pre-existing cognitive deficits. PMID:27017491

Hot air ablowin! 'Media-speak', social conflict, and the Australian 'decoupled' wind farm controversy.

PubMed

Hindmarsh, Richard

2014-04-01

In work in science, technology, and society social conflict around wind farms has a growing profile, not least because it draws our attention to two key interrelated themes: 'science, technology and governance' and 'socio-technological systems'. In this article on Australian wind farm development and siting, these themes are highlighted in contexts of sustainability, legitimacy, and competency for policy effectiveness. There is enduring social conflict around wind farms at the local community level, but little government understanding of this conflict or willingness to respond adequately to resolve it. This article examines the conflict through the lens of print media analysis. A key finding of the five identified is that people seeing wind farms as spoiling a sense of place is a primary cause of enduring social conflict at the local community level around wind farms, alongside significant environmental issues and inadequate community engagement; this finding also indicates a central reason for the highly problematic state of Australian wind energy transitions. In turn, by identifying this problematic situation as one of a significantly 'decoupled' and 'dysfunctional' condition of the Australian socio-technological wind farm development and siting system, I suggest remedies including those of a deliberative nature that also respond to the Habermas-Mouffe debate. These inform a socio-technical siting approach or pathway to better respect and navigate contested landscapes for enhanced renewable energy transitions at the local level.

ADHD and risky sexual behavior in adolescents: Conduct problems and substance use as mediators of risk

2015-01-01

Background Recent studies have linked attention-deficit/hyperactivity disorder (ADHD) to elevated rates of risky sexual behavior (RSB) in adult samples. The current study tested whether ADHD symptoms were associated with RSB among adolescents, and examined comorbid conduct problems and problematic substance use as joint mediators of this association. Methods ADHD symptoms, conduct problems (oppositional defiant disorder/conduct disorder symptoms), problematic alcohol use (alcohol use disorder symptoms, alcohol use frequency), problematic marijuana use (marijuana use disorder symptoms, marijuana use frequency), and RSB were assessed among an ethnically diverse cross-sectional sample of adolescents (N=115; mean age=14.9 years) involved in the juvenile justice system. Results Bootstrapped mediation models revealed an initial association between ADHD symptoms and RSB that was accounted for fully by the influence of problematic alcohol and marijuana use, but not conduct problems. A follow-up multiple groups mediation analysis demonstrated that the relationship between ADHD symptoms and RSB emerged only among youth with clinically elevated conduct problems, and that problematic marijuana use fully accounted for this relationship. Hyperactive/impulsive but not inattentive symptoms were related to RSB, although the pattern of indirect effects was consistent with the multiple groups analysis. Conclusions The association between ADHD and adolescent RSB is restricted to youth with elevated comorbid conduct problems and reflects the contributions of comorbid marijuana use problems, and to a lesser extent alcohol use problems. Early identification and treatment of these comorbid conditions may be important for the prevention of negative sexual health outcomes among youth with ADHD. PMID:24813803

Monitoring the Impact of Solution Concepts within a Given Problematic

NASA Astrophysics Data System (ADS)

Cavallucci, Denis; Rousselot, François; Zanni, Cecilia

It is acknowledged that one of the most critical issues facing today’s organizations concerns the substantial leaps required to methodologically structure innovation. Among other published work, some suggest that a complete rethinking of current practices is required. In this article, we propose a methodology aiming at providing controlled R&D choices based on a monitoring of the impact Solution Concepts provoke on a problematic situation. Initially this problematic situation is modeled in a graph form, namely a Problem Graph. It has the objective to assists R&D managers when choosing which activities to support and bring them concrete arguments to defend their choices. We postulate that by improving the robustness of such approaches we help deciders to switch from intuitive decisions (mostly built upon their past experiences, fear regarding risks, and awareness of the company’s level of acceptance of novelties) to thoroughly constructed inventive problem solving strategies. Our approach will be discussed using a computer application that illustrates our hypothesis after being tested in several industrial applications.

Tensions between work and home: job quality and working conditions in the institutional contexts of Germany and Spain.

PubMed

Drobnič, Sonja; Guillén Rodríguez, Ana M

2011-01-01

Good jobs can generate capabilities that allow employees to avoid tensions between work and family/home. Following the conceptual framework of Amartya Sen, we examine how job-related demands and resources are related to the level of interference, as well as satisfaction with managing work and home in Spanish and German employees, using three different large-scale European surveys: European Quality of Life Survey and two waves of the European Social Survey. We find that long working hours systematically increase tensions between work and home, as do time pressure, job-related stress, and working hard. Job control or autonomy at work, which is hypothesized to expand individuals' capabilities and agency, tends to increase work–home interference rather than alleviate it. Family responsibilities and household demands do not seem relevant to the tensions employees experience at the work–home interface. This also holds true for women, which is a surprising result in view of the “double burden” hypothesis. Employed mothers in Germany and Spain are a select group of women, as combining employment with raising children in conservative–corporatist and conservative–familialist states may be particularly problematic. Thus while the institutional contexts of Germany and Spain curtail women's ability to reconcile employment and parenthood, the mothers (and fathers) who are employed do not experience significantly higher levels of work–family/home tensions than nonparents.

Problematic alcohol consumption is associated with a high disease burden for affected individuals and has a detrimental impact on companies and society due to direct and indirect health costs. This protocol describes a study design to evaluate the (cost)-effectiveness of a guided and unguided Internet-based self-help intervention for employees called "GET.ON Clever weniger trinken" (be smart - drink less) compared to a waiting list control group. In a three-arm randomized controlled trial, 528 German adults who are currently members of the workforce will be recruited by occupational health departments of major health insurance companies. Employees aged 18 and older displaying problematic drinking patterns (>21/14 drinks per week and an AUDIT score > 8/6 for men/women) will be randomly assigned to one of three following study conditions: 1. unguided web-based self-help for problematic drinking, 2. adherence-focused guided self-help, and 3. waiting list control. Self-report data will be collected at baseline (T1), 6 weeks (T2), and 6 months (T3) after randomization. The primary outcome will be the reduction of alcohol standard units during the 7 days prior to T2, using the Timeline Followback method. Cost-effectiveness analyses to determine direct and indirect costs will be conducted from the perspectives of employers and the society. Data will be analyzed on an intention-to-treat basis and per protocol. There is a need to identify effective low-threshold solutions to improve ill-health and reduce the negative economic consequences due to problematic alcohol drinking in workforces. If the proposed web-based intervention proves both to be efficacious and cost-effective, it may be a useful tool to increase utilization rates of interventions for problematic drinking in occupational settings.

Psychosocial aspects of working with video display terminals (VDTs) and employee physical and mental health.

PubMed

Smith, M J

1997-10-01

Psychosocial aspects of using video display terminals (VDTs) have been recognized as contributors to employees' mental and physical health problems for more than 15 years. Yet, little has been done by employers to change work organization conditions to improve the psychosocial work environment of VDT users. Thus, psychosocial aspects of work are emerging as one of the biggest problems for VDT users in the late 1990s. This paper explores how psychosocial aspects of VDT work are related to job stress, and their consequences for mental and physical health. Using the research literature, it defines various aspects of work organization and job design that have been shown to be related to VDT users' ill-health. Some of the important work design aspects uncovered include a lack of employee skill use, monotonous tasks, high job demands and work pressure, a lack of control over the job, poor supervisory relations, fear of job loss, and unreliable technology. These are the same job stressors that have been defined as problematic for a variety of blue collar jobs in previous research. Work organization improvements for healthier VDT jobs are proposed. These include organizational support, employee participation, improved task content, increased job control, reasonable production standards, career development, enhanced peer socialization, and improved workstation ergonomics. These organizational improvements are derived from a more detailed organizational strategy for job stress reduction. A model of job redesign through proper 'balancing' of work organization features is discussed.

Diagnostic guidelines for newborns who screen positive in newborn screening.

Recent expansion of the newborn screening panels has presented an interesting challenge to specialty care centers, especially the clinical genetics community. Some of the conditions in the core and secondary newborn screening panels have extremely variable clinical presentations; others are so rare that only a handful of newborns have been diagnosed with them to date (Region 4 Collaborative MS/MS project-http://region4genetics.org/msms_data_project/data_project_home.aspx). Definition of some disorders is problematic-does continued abnormality of the screening analyte constitute diagnosis or is further testing necessary? A work group of the New York Mid-Atlantic Consortium for Genetic and Newborn Screening Services (region 2), one of seven regional collaboratives funded by the Federal Health Resources and Services Administration and administered by the Maternal and Child Health Bureau (U22MC03956), has developed guidelines for the confirmation of diagnosis of the conditions in the newborn screening panels for use by the specialty care centers. The diagnostic guidelines are a work in progress and are being reviewed and revised regularly as our understanding of the newborn screened disorders improves. The aim is to make it a relevant guide for specialty care physicians and other healthcare professionals in the diagnostic workup of these patients.

Autism is a chronic and lifelong pervasive developmental disorder for which there is yet no effective cure, and medical management remains a major challenge for clinicians. In spite of the possible similarities with conditions that have an established pharmacotherapy, and despite improvements in some associated "problematic behaviors" following the use of available medications, effective medical treatment for the core symptoms involving language and social cognition remains elusive. The purpose of the present article is to review current biologic knowledge about autism in an attempt to correlate clinical trials with known mechanisms of disease. In addition, the need for controlled studies and for the creation of homogeneous subgroups of patients based on clinical and genetic characteristics is emphasized. The application of molecular genetic investigations and pharmacogenetics in the diagnostic work-up of autistic patients can lead to more effective individualized medical care.

Internet addiction disorder (IAD) is characterized by the problematic use of online video games, computer use, and mobile handheld devices. While not officially a clinical diagnosis according to the most recent version of the Diagnostic and Statistical Manual of Mental Disorders (DSM), individuals with IAD manifest severe emotional, social, and mental dysfunction in multiple areas of daily activities due to their problematic use of technology and the internet. We report a 31year-old man who exhibited problematic use of Google Glass™. The patient has a history of a mood disorder most consistent with a substance induced hypomania overlaying a depressive disorder, anxiety disorder with characteristics of social phobia and obsessive compulsive disorder, and severe alcohol and tobacco use disorders. During his residential treatment program at the Navy's Substance Abuse and Recovery Program (SARP) for alcohol use disorder, it was noted that the patient exhibited significant frustration and irritability related to not being able to use his Google Glass™. The patient exhibited a notable, nearly involuntary movement of the right hand up to his temple area and tapping it with his forefinger. He reported that if he had been prevented from wearing the device while at work, he would become extremely irritable and argumentative. Over the course of his 35-day residential treatment, the patient noted a reduction in irritability, reduction in motor movements to his temple to turn on the device, and improvements in his short-term memory and clarity of thought processes. He continued to intermittently experience dreams as if looking through the device. To our knowledge, this is the first reported case of IAD involving problematic use of Google Glass™.

2016-09-01

Socially anxious college students are at increased risk for engaging in problematic drinking (i.e. heavy or risky drinking) behaviors that are associated with the development of an alcohol use disorder. The present study examined whether post-event processing (PEP), repeatedly thinking about and evaluating one's performance in a past social situation, strengthens the association between social anxiety and vulnerability to problematic drinking among college students. Eighty-three college drinkers with high or low social anxiety participated in a social interaction task and were exposed to a manipulation that either promoted or inhibited PEP about the social interaction. Among participants randomized to the PEP promotion condition, those with high social anxiety exhibited a greater urge to use alcohol after the social interaction and greater motivation to drink to cope with depressive symptoms over the week following the manipulation than did those with low social anxiety. These findings suggest that targeting PEP in college drinking intervention programs may improve the efficacy of such programs for socially anxious students.

Understanding social inclusion among at-risk populations will deepen our understanding of their specific needs. This study explored the level of social inclusion among people with psychotic-related conditions using a standardised interview. The Social Inclusion Interview Schedule was used in two research projects. People with psychosis participated in both studies and had been recruited as part of an Irish programme of research on psychotic conditions. Descriptive statistics were used to quantify participants' level of social exclusion. Data from 71 participants were available, 38 in one cohort and 33 in the other. The smaller cohort had a shorter mean duration of illness. Participants' mean age was 40. The majority lived in the community and were satisfied with their living arrangements. In each cohort, the same two areas of community integration emerged as problematic - having something productive to do and being close to someone in the community. There was a higher level of perceived stigma among the cohort with the longer duration of illness. While evidence of social inclusion was found among participants, there were areas of concern particularly with regard to integration into work and social connectedness.

High Performance Double-null Plasma Operation Under Radiating Divertor Conditions

We report on heat flux reduction experiments in which deuterium/neon- or deuterium/argon-based radiating mantle/divertor approaches were applied to high performance double-null (DN) plasmas (H98 1.4-1.7,βN 4 , q 95 6) with a combined neutral beam and ECH power input PIN 15 MW. When the radial location of the ECH deposition is close to the magnetic axis (e.g., ρ <=0.20), the radial profiles of both injected and intrinsic impurities are flat to somewhat hollow. For deposition farther out (e.g., ρ=0.45), the impurity profiles are highly peaked on axis, which would make high performance DN operation with impurity injection more problematical. Comparison of neon with argon `seeding' with respect to core dilution, energy confinement, and heat flux reduction under these conditions favors argon. Conditions that lead to an improved τE as predicted previously from ELITE code analysis, i.e., very high PIN, proximity to magnetic balance, and higher q95, are largely consistent with this data.

Geotechnical zoning of urban foundations: Avilés case study (N Spain)

2014-05-01

The purpose of this paper is to carry out a geotechnical evaluation of the underground within an urban setting in relation to types of foundations, and particularly at expansion zones. The ultimate aim is to produce a foundation zonation map at the scale 1:10,000. Furthermore, a general methodology that way be extrapolated to other cities is proposed. This work focused on the city of Aviles like a case study; a medium-sized city which has significant industrial and port areas and singular equipment in its surroundings. This city is located in the Spanish north coast and spread out on both flanks of the Avilés stuary. This means that there are an important development of recent deposits that implies different geotechnical units with a highly variable behavior, generally poor. In contrast, the bedrock is more homogenous, formed by Permo-Triassic red clay and marl. Locally there are also outcrops of carbonates and conglomeratic Jurassic levels. Also, on the whole area is important to note the presence of heterogeneous anthropic deposits along the whole area as a consequence, mainly, of an intense industrial activity. Permo-Triassic clayey and marly materials imply special engineering issues in foundations as a consequence of their composition (likely weathering, presence of gypsum, low bearing capacity). Moreover, recent deposits (marine and alluvial origin) show different geotechnical behaviors depending on their geometry and grain size. Hence, many areas of the city are especially problematic when designing and implementing foundations. The methodology followed in this study consisted in elaborating a geological-geotechnical exhaustive survey of the urban underground on a scale of 1/10.000. Based on this, a multi criteria analysis of the identified geotechnical units was carried out taking into consideration all the lithological, geomorphological, hidrogeological and geotechnical aspects. Taken into account all of these criteria, a number of areas are defined based on their foundation conditions: i) good ground conditions (rocks: UCS > 25 MPa); ii) acceptable ground conditions (rocks: UCS 5-25 MPa); iii) bad ground conditions (soils and rocks: UCS < 5 MPa and sulfate rich soils) and iv) problematic ground conditions (special geological hazards). A foundation zonation map is a basic document for adequate land-use planning for instrastructures and edification, being useful to society, industrial and public sectors.

Occupational medicine for policing.

PubMed

Trottier, A; Brown, J

1995-06-01

A wide variety of medical conditions may be associated with police work. Unlike other occupations where a specific link can be traced between an exposure or an action and a specific pathology, the link between police work and disease is more problematic. The medical conditions which seem to be associated with police work are all conditions for which numerous other risk factors are identifiable. These risk factors include physical inactivity, poor nutritional practices, cigarette smoking and alcohol overuse. While it is undoubtedly desirable to minimise these risk factors in any patient population it is imperative, given the increased risks among police personnel, that aggressive attempts he undertaken to reduce cumulative risks. The physician plays an important part in this process by screening for specific conditions associated with police work, by educating the police officer about increased risks and by encouraging lifestyle choices that will reduce risk. It is also important that the physician encourages the use of personal protective equipment where appropriate. Periodic health assessment of police officers by a physician knowledgeable about police work should include education about the risks associated with the occupation and about methods to reduce risk. The physician should also enquire about exposures to violent or dangerous occurrences and should include assessment for possible emotional sequelae of such exposure. Operational procedures designed to reduce risk of violence and to improve police officer safety and survival are appropriate but are not in the normal realm of the physician. The question of whether a medical condition may be attributable to the occupation of policing is liable to produce strong emotions. When a police officer becomes ill there is an understandable desire on the part of other officers and, often, on the part of the public, to attempt to demonstrate a connection between the occupation and the illness. In line with this tendency several US states have policies in place to unquestioningly accept atherosclerotic heart disease among police officers as 'occupationally induced' for pension purposes. This leads to situations where the scientific evidence may be at odds with the political agenda of individuals and groups participating in the determination. This review will examine the evidence for a number of medical conditions. Specific occupational exposures, such as lead exposure among ballistics specialists, or chemical exposure among forensic laboratory workers are addressed elsewhere. Biohazard risks will be addressed in a later review.

Binge eating disorder (BED) shares many characteristics with addictive behaviors (e.g., diminished control, continued use despite negative consequences), and a body of scientific literature is building to support addiction conceptualizations of problematic eating. Despite similarities, BED and "food addiction" may represent unique yet overlapping conditions. Although the exploration of food addiction is relatively new, understanding the relationship between food addiction and BED may be informative in understanding the mechanisms underlying the development and maintenance of problematic eating. In the following paper, we 1) examine the theoretical similarities and differences between BED and addiction, 2) review recent empirical evidence that speak to the relationship between BED and food addiction and 3) discuss the implications of associations between BED and food addiction with respect to clinical interventions.

Studies have shown that interpersonal relations at work are important for several health related outcomes. The aim of the present study was to investigate whether low social support, serious conflict, exclusion by superiors or by co-workers at work may be determinants of depression. In a representative Swedish cohort study data were obtained in two waves three years apart. 4,040 women and men who did not change their jobs between the waves were chosen for the study. Exposure and confounders were obtained at Time 1 and outcome, depression according to Bech's MDI at Time 2. Previous depression was controlled for by adjusting for depression at Time 1. Data were analyzed using multiple logistic regression analyses. Odds-ratios adjusted for possible confounders and depression at base-line showed significant effects for all four exposures on depression (adjusted OR, low social support 1.5 CI 95% 1.1-2.0, serious conflict 1.4 CI 95% 1.1-1.9, exclusion by superiors 1.6 CI 95% 1.2-2.1 and exclusion by co-workers 1.7 CI 95% 1.2-2.3). The present results support the conclusion that problematic interpersonal relationships at work can be determinants of depression. These prospective findings may be of relevance for prevention and when rehabilitating depressed patients.

Little is known on how employees at work with mental health problems experience their work environment. This study explores how a selected sample of Danish employees with depressive symptoms experience the interaction with their work environment and how they respond to and deal with problems at work. From a survey study on work and mental health in Denmark, we invited participants for in-depth interviews. Using grounded theory, we conducted 13 semi structured interviews with employees, at work, experiencing depressive symptoms. Work was pivotal for the informants who were in an on-going process that we conceptualised as struggling at work. Informants struggled with the negative experiences of work that led to emotional, cognitive and somatic symptoms. Relationships with supervisors and colleagues, work load and work pressure and their self-image as a good worker conditioned the struggle. The informants found themselves unable to change their problematic working situation. This gradually led to different strategies to endure work and take care of one-self. These strategies were as follows: tending to symptoms and altering prospects for their future. The consequence of the on-going struggle was that the informants distanced themselves from their work. This study provided insight to the process of struggling at work, which the interviewed employees with depressive symptoms experienced. Behaviour of supervisors is a key element for employees with depressive symptoms struggling at work. Practitioners and other health and rehabilitation practitioners working with people with depressive symptoms and other mental health problems could inquire about supervisor's behaviour and relation between supervisors and employees. Interventions that targets both the individual employee as well as work environment focused interventions at the organisational level could be beneficial for employees with mental health problems as well as the workplaces.

Chemical stabilization of air pollution control residues from municipal solid waste incineration.

2010-07-15

The by-products of the municipal solid waste incineration (MSWI) generally contain hazardous pollutants, with particular relevance to air pollution control (APC) residues. This waste may be harmful to health and detrimental to the environmental condition, mainly due to soluble salts, toxic heavy metals and trace organic compounds. Solidification/stabilization (S/S) with binders is a common industrial technology for treating such residues, involving however, a significant increase in the final mass that is landfilled. In our work, the chemical stabilization of APC residues by using NaHS x xH(2)O, H(3)PO(4), Na(2)CO(3), C(5)H(10)NNaS(2) x 3 H(2)O, Na(2)O x SiO(2) was investigated, and it was possible to conclude that all these additives lead to an improvement of the stabilization process of the most problematic heavy metals. Indeed, compliance leaching tests showed that after the stabilization treatment the waste becomes non-hazardous with respect to heavy metals. Chromium revealed to be a problematic metal, mainly when H(3)PO(4), Na(2)CO(3) and Na(2)O x SiO(2) were used for stabilization. Nevertheless, soluble phosphates are the most efficient additives for stabilizing the overall metals. The effect of the additives tested on the elements associated with soluble salts (K, Na, Cl(-)) is almost negligible, and therefore, the soluble fraction is hardly reduced without further treatment, such as pre-washing. 2010 Elsevier B.V.

Legitimation problems of participatory processes in technology assessment and technology policy.

PubMed

Saretzki, Thomas

2012-11-01

Since James Carroll (1971) made a strong case for "participatory technology", scientists, engineers, policy-makers and the public at large have seen quite a number of different approaches to design and implement participatory processes in technology assessment and technology policy. As these participatory experiments and practices spread over the last two decades, one could easily get the impression that participation turned from a theoretical normative claim to a working practice that goes without saying. Looking beyond the well-known forerunners and considering the ambivalent experiences that have been made under different conditions in various places, however, the "if" and "how" of participation are still contested issues when questions of technology are on the agenda. Legitimation problems indicate that attempts to justify participation in a given case have not been entirely successful in the eyes of relevant groups among the sponsors, participants, organizers or observers. Legitimation problems of participatory processes in technology assessment and technology policy vary considerably, and they do so not only with the two domains and the ways of their interrelation or the specific features of the participatory processes. If we ask whether or not participation is seen as problematic in technology assessment and technology policy-making and in what sense it is being evaluated as problematic, then we find that the answer depends also on the approaches and criteria that have been used to legitimize or delegitimize the call for a specific design of participation.

While addictions to substances such as alcohol, tobacco, and other drugs have been extensively investigated, interest has been growing in potential non-substance-related addictive behaviors (e.g., excessive gambling, buying or playing video games). In the current study, we sought to determine the prevalence and characteristics of a wide range of addictive behaviors in a general population sample and to identify reliable subgroups of individuals displaying addictive behaviors. Seven hundred seventy participants completed an online survey. The survey screened for the presence and characteristics of the main recognized substance and behavioral addictions (alcohol, tobacco, cannabis, other drugs, gambling, compulsive shopping, intensive exercise, Internet and mobile phone overuse, intensive work involvement, and overeating) in a three-month period. Key aspects of addiction were measured for each reported behavior, including negative outcomes, emotional triggers (positive and negative emotional contexts), search for stimulation or pleasure, loss of control, and cognitive salience. Latent class analysis allowed us to identify three theoretically and clinically relevant subgroups of individuals. The first class groups problematic users, i.e., addiction-prone individuals. The second class groups at-risk users who frequently engage in potentially addictive behaviors to regulate emotional states (especially overinvolvement in common behaviors such as eating, working, or buying). The third class groups individuals who are not prone to addictive behaviors. The existence of different groups in the population sheds new light on the distinction between problematic and non-problematic addiction-like behaviors.

Stress at work: development of the Stress Perception Questionnaire of Rome (SPQR), an ad hoc questionnaire for multidimensional assessment of work related stress.

Cinti, M E; Cannavò, M; Fioravanti, M

2017-01-01

Stress is an emotional condition, mostly experienced as negative, initially identified and defined by Selye in the mid-thirties of the last Century. Since the first definition, stress concerns the adaptation pro- cess mostly related to environmental changes. An application of stress focuses on the evaluation of its interference on work conditions, and the scientific evidence on work related stress is very ample and rich. We are proposing a new ad hoc questionnaire for the multidimensional assessment of work related stress, called Stress Perception Question- naire of Rome (SPQR) composed of 50 items. The development of this questionnaire is based on a multi-step process: a) Identification of all the relevant topics to work related stress and areas in the scientific evidence and their transformation on specific contents of 60 tentative items; b) Exploratory factor analysis aimed to identify the best items (50) which could guarantee the maximum convergence on single scales (8), and the minimum redundancy between scales; c) Validation of the 8 scales' structure by a confirmatory factor analysis (fully achieved); d) Factor analysis for a second level factor resulting in a single factor identified as the questionnaire total score (Stress Score); d) Reliability analysis of the questionnaire total score and the single scale scores (at optimum level); e) Validation by external criteria of work related stress identified in the presence of personal violence episodes experienced by a group of health workers with different professional profiles and from two different hospitals in Rome. Our results show that the SPQR is a useful and sensitive tool for assessing the presence of emotional stress related problems identifiable in a work environment. The advantage of this questionnaire is that it allows for a multidimensional description of the different components of this problematic area besides its ability to quantify the overall stress level of those who have been administered the SPQR.

This study explores the two-year housing- and non-housing-related outcomes for adults who are homeless with problematic substance use who received scattered-site housing and intensive case management services from a Housing First program in Ottawa, Canada, in comparison with a group of adults who are homeless with problematic substance use who had access to standard care in the community. Housing First clients (n = 89) and members of a comparison group (n = 89) completed structured interviews at baseline and were followed for two years. Housing First clients moved into housing more quickly, reported a greater proportion of time housed, were more likely to spend the final six months housed, and had longer housing tenure at 24 months. There was a group by time interaction on problematic alcohol use with more rapid improvement for the comparison group; however, both groups improved over time. The comparison group had a greater decrease on problematic drug use by 24 months. There was no change in physical health and only the comparison group had improvements in mental health by 24 months. The groups had similar improvement on community functioning by 24 months. The comparison group had a greater increase in total quality of life. More specifically, the comparison group had an increase in the family relations-related quality of life, whereas the clients did not. There was a significant interaction for safety-related quality of life, but both groups experienced improvements over time and had comparable levels of satisfaction with safety at each time point. The Housing First clients reported higher levels of satisfaction with living conditions than the comparison group at baseline and 12 months, but not at 24 months. There was significant improvement over time and no main effect of group for finances, leisure, and social relations. Adults who are homeless with problematic substance use can successfully be housed using a Housing First approach. However, further targeted services might be required to address other areas of functioning, such as health, substance use, and quality of life.

Problematic versus non-problematic ecstasy/MDMA use: the influence of drug usage patterns and pre-existing psychiatric factors.

Soar, K; Turner, J J D; Parrott, A C

2006-05-01

Recreational ecstasy (3,4-methylenedioxymethamphetamine; MDMA) use has been increasingly associated with a number of psychiatric symptoms and psychological problems. However, previous studies assessing possible psychopathological effects have not identified whether users consider their ecstasy use "problematic" or not. In addition, research has generally failed to address the potential role of premorbid psychiatric status. This study aimed to assess whether premorbid psychiatric history and/or patterns of ecstasy use would be associated with the degree of self-reported problems attributable to ecstasy. Problematic ecstasy users (n = 53) who had reported problems attributable to their ecstasy use were compared with non-problematic ecstasy users (n = 62), polydrug controls (n = 62) and illegal drug-naive controls (n = 111) on a recreational drug use questionnaire; a questionnaire, which ascertained personal and family psychiatric histories, and the Brief Symptom Inventory (BSI). Problematic ecstasy users exhibited significantly higher scores on a number of dimensions of the BSI compared to illegal drug-naive and/or polydrug controls. Problematic ecstasy users also exhibited significantly elevated scores on somatization, depression, anxiety and negative psychobiology compared to non-problematic ecstasy users. BSI scores for the non-problematic ecstasy users did not differ from polydrug or illegal drug-naive controls. Problematic ecstasy users reported significantly higher levels of ecstasy use, including lifetime consumption, average dosage and binge consumption compared to non-problematic ecstasy users. Additionally, a greater number of problematic ecstasy users reported personal and family psychiatric histories compared to controls and non-problematic ecstasy users. This study demonstrates two distinct ecstasy using groups: non-problematic ecstasy users who are not showing signs of psychopathology and problematic ecstasy users who are showing evidence of a range of symptoms. This data therefore partially supports the link between ecstasy dosage and negative psychological sequelae, but highlights the importance of the need to consider ecstasy-related attributions, pre-existing mental health status and vulnerability.

2015-01-01

Objective The goal of the present investigation was to develop and test a brief therapist-guided manualized treatment for problematic caffeine use including cognitive-behavioral strategies and 5-weeks of progressively decreased consumption. Methods Individuals seeking treatment for problematic caffeine use (mean daily caffeine consumption of 666.0 mg at baseline) were randomized using a waitlist-control design to receive immediate (N = 33) treatment or delayed (N = 34) treatment (∼6 weeks later). A one-hour long treatment session designed to help individuals quit or reduce caffeine consumption was provided by a trained counselor along with a take-home booklet. After the treatment session, participants completed daily diaries of caffeine consumption for 5 weeks. They returned for follow-up assessments at 6, 12, and 26 weeks and had a telephone interview at 52-weeks post-treatment. Results Treatment resulted in a significant reduction in self reported caffeine use and salivary caffeine levels. No significant post-treatment increases in caffeine use were observed for up to one year follow-up. Comparisons to the waitlist control condition revealed that reductions in caffeine consumption were due to treatment and not the passing of time, with a treatment effect size of R2 = .35 for the model. Conclusions A brief one-session manualized intervention with follow-up was efficacious at reducing caffeine consumption. Future research should replicate and extend these findings, as well as consider factors affecting dissemination of treatment for problematic caffeine use to those in need. PMID:26501499

Problematic Internet Use among Greek university students: an ordinal logistic regression with risk factors of negative psychological beliefs, pornographic sites, and online games.

2011-01-01

The aim of this paper is to investigate the relationships between Problematic Internet Use (PIU) among university students in Greece and factors such as gender, age, family condition, academic performance in the last semester of their studies, enrollment in unemployment programs, amount of Internet use per week (in general and per application), additional personal habits or dependencies (number of coffees, alcoholic drinks drunk per day, taking substances, cigarettes smoked per day), and negative psychological beliefs. Data were gathered from 2,358 university students from across Greece. The prevalence of PIU was 34.7% in our sample, and PIU was significantly associated with gender, parental family status, grade of studies during the previous semester, staying or not with parents, enrollment of the student in an unemployment program, and whether the student paid a subscription to the Internet (p < 0.0001). On average, problematic Internet users use MSN, forums, YouTube, pornographic sites, chat rooms, advertisement sites, Google, Yahoo!, their e-mail, ftp, games, and blogs more than non-problematic Internet users. PIU was also associated with other potential addictive personal habits of smoking, drinking alcohol or coffee, and taking drugs. Significant risk factors for PIU were being male, enrolment in unemployment programs, presence of negative beliefs, visiting pornographic sites, and playing online games. Thus PIU is prevalent among Greek university students and attention should be given to it by health officials.

To investigate co-occurrence and shared personality characteristics of problematic computer gaming, problematic gambling and substance use. Cross-sectional survey data were collected from 2,553 German students aged 12-25 years. Self-report measures of substance use (alcohol, tobacco and cannabis), problematic gambling (South Oaks Gambling Screen - Revised for Adolescents, SOGS-RA), problematic computer gaming (Video Game Dependency Scale, KFN-CSAS-II), and of twelve different personality characteristics were obtained. Analyses revealed positive correlations between tobacco, alcohol and cannabis use and a smaller positive correlation between problematic gambling and problematic computer gaming. Problematic computer gaming co-occurred only with cannabis use, whereas problematic gambling was associated with all three types of substance use. Multivariate multilevel analyses showed differential patterns of personality characteristics. High impulsivity was the only personality characteristic associated with all five addictive behaviours. Depression and extraversion were specific to substance users. Four personality characteristics were specifically associated with problematic computer gaming: irritability/aggression, social anxiety, ADHD, and low self-esteem. Problematic gamblers seem to be more similar to substance users than problematic computer gamers. From a personality perspective, results correspond to the inclusion of gambling in the same DSM-V category as substance use and question a one-to-one proceeding for computer gaming.

A Systematic Review of Interventions to Reduce Problematic Substance Use Among Transgender Individuals: A Call to Action

2017-01-01

Abstract Persons who are transgender (i.e., individuals who are assigned one sex at birth, but who do not identify with that sex) are at elevated risk for developing problematic substance use. Recent studies indicate that transgender persons have high rates of alcohol use, illicit drug use, and nonmedical use of prescription drugs and evince more severe misuse of these substances compared with nontransgender individuals. Despite the high rates of substance use among transgender persons and the multiple conceptual and narrative recommendations for substance use treatments, there is a lack of consensus or awareness of empirically tested interventions and programs effective for this population. Thus, it is critical to examine current substance use interventions for transgender individuals to identify gaps in the field and to immediately put forth efforts to reduce problematic substance use. This systematic review is the first to attempt a comprehensive identification and synthesis of the available evidence on interventions for reducing problematic substance use among transgender persons. Reflective of the state of the field regarding transgender care for substance use, we found a deficiency of studies to include in this systematic review (n=2). Perhaps the most important conclusion of this review is that well-designed, theoretically informed culturally sensitive research focused on developing and rigorously testing interventions for substance use among transgender individuals is alarmingly scarce. This review discusses barriers to intervention design and synthesizes treatment recommendations for future work. PMID:28861547

Withdrawing to a virtual world: Associations between subtypes of withdrawal, media use, and maladjustment in emerging adults.

An approach-avoidance model of social withdrawal (Asendorpf, 1990) identifies 3 types of social withdrawal including shyness, unsociability, and avoidance. Each appears to be uniquely associated with varying indicators of maladjustment in emerging adulthood (Nelson, 2013) but little, if any, work has been done to see how they might be linked to media use in the third decade of life. Therefore, the purpose of this study was to examine longitudinally the links between subtypes of social withdrawal, connective media (e.g., e-mail, social networking) and problematic (forms of media such as violent video games that, when used in high amounts, have been found to be linked to indices of maladjustment) media use, and internalizing and externalizing behaviors. The participants in the study (Mage = 20.70, SD = 1.98, range = 18-29 at Time 2) consisted of 204 undergraduate students (58% female) recruited from 2 large public universities in the United States who completed questionnaires at 2 points of time separated by 1 year. Results revealed that avoidant individuals use problematic forms of media more than average, unsociable, and shy individuals. Furthermore, problematic media use predicted more withdrawn behavior at Time 2 and mediated the relation between avoidance and externalizing behaviors over time. Few problems were found for unsociable behavior. The need to differentiate between multiple forms of withdrawal in emerging adulthood and their links with problematic forms of media and subsequent risk factors is discussed.

To assess prevalence rates and correlates of problematic use of prescription opioids and medicinal cannabis (MC) among patients receiving treatment for chronic pain. Cross-sectional study. Two leading pain clinics in Israel. Our sample included 888 individuals receiving treatment for chronic pain, of whom 99.4% received treatment with prescription opioids or MC. Problematic use of prescription opioids and MC was assessed using DSM-IV criteria, Portenoy’s Criteria (PC), and the Current Opioid Misuse Measure (COMM) questionnaire. Additional sociodemographic and clinical correlates of problematic use were also assessed. Among individuals treated with prescription opioids, prevalence of problematic use of opioids according to DSM-IV, PC, and COMM was 52.6%, 17.1%, and 28.7%, respectively. Among those treated with MC, prevalence of problematic use of cannabis according to DSM-IV and PC was 21.2% and 10.6%, respectively. Problematic use of opioids and cannabis was more common in individuals using medications for longer periods of time, reporting higher levels of depression and anxiety, and using alcohol or drugs. Problematic use of opioids was associated with higher self-reported levels of pain, and problematic use of cannabis was more common among individuals using larger amounts of MC. Problematic use of opioids is common among chronic pain patients treated with prescription opioids and is more prevalent than problematic use of cannabis among those receiving MC. Pain patients should be screened for risk factors for problematic use before initiating long-term treatment for pain-control.

Complex research questions often cannot be addressed adequately with a single data set. One sensible alternative to the high cost and effort associated with the creation of large new data sets is to combine existing data sets containing variables related to the constructs of interest. The goal of the present research was to develop a flexible, broadly applicable approach to the integration of disparate data sets that is based on nonparametric multiple imputation and the collection of data from a convenient, de novo calibration sample. We demonstrate proof of concept for the approach by integrating three existing data sets containing items related to the extent of problematic alcohol use and associations with deviant peers. We discuss both necessary conditions for the approach to work well and potential strengths and weaknesses of the method compared to other data set integration approaches.

Approximately 60 % of the 2,150,000 km2 area of Saudi Arabia is underlain by soluble sediments (carbonate and evaporite rock formations, salt diapirs, sabkha deposits). Despite its hyper-arid climate, a wide variety of recent sinkholes have been reported in numerous areas, involving significant property losses. Human activities, most notably groundwater extraction, have induced unstable conditions on pre-existing cavities. This work provides an overview of the sinkhole hazard in Saudi Arabia, a scarcely explored topic. It identifies the main karst formations and the distribution of the most problematic sinkhole areas, illustrated through several case studies covering the wide spectrum of subsidence mechanisms. Some of the main investigation methods are presented through selected examples, including remote sensing, trenching and geophysics. Based on the available data, the main causal factors are identified and further actions that should be undertaken to better assess and manage the risk are discussed.

Molybdenum Disulfide as a Protection Layer and Catalyst for Gallium Indium Phosphide Solar Water Splitting Photocathodes

Gallium indium phosphide (GaInP2) is a semiconductor with promising optical and electronic properties for solar water splitting, but its surface stability is problematic as it undergoes significant chemical and electrochemical corrosion in aqueous electrolytes. Molybdenum disulfide (MoS2) nanomaterials are promising to both protect GaInP2 and to improve catalysis since MoS2 is resistant to corrosion and also possesses high activity for the hydrogen evolution reaction (HER). In this work, we demonstrate that GaInP2 photocathodes coated with thin MoS2 surface protecting layers exhibit excellent activity and stability for solar hydrogen production, with no loss in performance (photocurrent onset potential, fill factor, andmore » light limited current density) after 60 hours of operation. This represents a five-hundred fold increase in stability compared to bare p-GaInP2 samples tested in identical conditions.« less

EEOC guidance on psychiatric disabilities: many problems, few workable solutions.

PubMed

McDonald, J J; Rosman, J P

1997-01-01

The EEOC recently issued "Enforcement Guidance" on psychiatric disabilities under the Americans with Disabilities Act. Although the Guidance provides clarification of a few issues involving mental disabilities under the ADA, in most respects the Guidance is problematic. For example, the Guidance suggests that the inability to get along with a supervisor or coworkers may constitute a disability under the ADA, that an employer may have to "accommodate" a disabled employee's misconduct, that an employer cannot require an employee to follow doctor's orders as a condition of employment, and that an employer may be obligated to modify work rules and procedures to accommodate a mentally disabled employee but is prohibited from explaining to coworkers why it is making such modifications. As the EEOC's Guidance exceeds or conflicts with the ADA in some respects and is largely unworkable in many respects, it remains to be seen how many courts will actually follow it.

Organohalide perovskites have emerged as highly promising replacements for thin-film solar cells. However, their poor stability under ambient conditions remains problematic, hindering commercial exploitation. The addition of a fluorous-functionalized imidazolium cation during the preparation of a highly stable cesium-based mixed perovskite material Cs 0.05 (MA 0.15 FA 0.85 ) 0.95 Pb(I 0.85 Br 0.15 ) 3 (MA=methylammonium; FA=formamidinium) has been shown to influence its stability. The resulting materials, which vary according to the amount of the fluorous-functionalized imidazolium cation present during fabrication, display a prolonged tolerance to atmospheric humidity (>100 days) along with power conversion efficiencies exceeding 16 %. This work provides a general route that can be implemented in a variety of perovskites and highlights a promising way to increase perovskite solar cell stability. © 2017 Wiley-VCH Verlag GmbH & Co.

The changing context of Western European healthcare systems: convergence versus divergence in nursing problematics.

Spitzer, Ada; Camus, Didier; Desaulles, Cécile; Kuhne, Nicolas

2006-10-01

Many countries reorganizing their health services are drawn toward similar reform programs and tend to experience what seem to be similar problems relating to implementation outcomes. One such problem is the major crisis within the nursing profession relating to the labor market, working conditions and level of autonomy. This research examines the thesis that the profile of nursing problems is global (the 'convergence' thesis) by comparing the changing hospital contexts nursing has been confronting in 20 Western European countries between 1990 and 2001. The analysis indicates that in spite of growing convergence, the divergence in patient care processes, workforce composition and resources allocated for care is still rather remarkable and that similarity or divergence between countries changes over time. This contextual variability highlights why problems such as the crisis of the nursing profession must be analysed from a divergent rather than a convergent perspective.

Assimilation approach to measuring organizational change from pre- to post-intervention

Moore, Scott C; Osatuke, Katerine; Howe, Steven R

2014-01-01

AIM: To present a conceptual and measurement strategy that allows to objectively, sensitively evaluate intervention progress based on data of participants’ perceptions of presenting problems. METHODS: We used as an example an organization development intervention at a United States Veterans Affairs medical center. Within a year, the intervention addressed the hospital’s initially serious problems and multiple stakeholders (employees, management, union representatives) reported satisfaction with progress made. Traditional quantitative outcome measures, however, failed to capture the strong positive impact consistently reported by several types of stakeholders in qualitative interviews. To address the paradox, full interview data describing the medical center pre- and post- intervention were examined applying a validated theoretical framework from another discipline: Psychotherapy research. The Assimilation model is a clinical-developmental theory that describes empirically grounded change levels in problematic experiences, e.g., problems reported by participants. The model, measure Assimilation of Problematic Experiences Scale (APES), and rating procedure have been previously applied across various populations and problem types, mainly in clinical but also in non-clinical settings. We applied the APES to the transcribed qualitative data of intervention participants’ interviews, using the method closely replicating prior assimilation research (the process whereby trained clinicians familiar with the Assimilation model work with full, transcribed interview data to assign the APES ratings). The APES ratings summarized levels of progress which was defined as participants’ assimilation level of problematic experiences, and compared from pre- to post-intervention. RESULTS: The results were consistent with participants’ own reported perceptions of the intervention impact. Increase in APES levels from pre- to post-intervention suggested improvement, missed in the previous quantitative measures (the Maslach Burnout Inventory and the Work Environment Scale). The progress specifically consisted of participants’ moving from the APES stages where the problematic experience was avoided, to the APES stages where awareness and attention to the problems were steadily sustained, although the problems were not yet fully processed or resolved. These results explain why the conventional outcome measures failed to reflect the intervention progress; they narrowly defined progress as resolution of the presenting problems and alleviation of symptomatic distress. In the Assimilation model, this definition only applies to a sub-segment of the change continuum, specifically the latest APES stages. The model defines progress as change in psychological processes used in response to the problem, i.e., a growing ability to deal with problematic issues non-defensively, manifested differently depending on APES stages. At early stages, progress is an increased ability to face the problem rather than turning away. At later APES stages, progress involves naming, understanding and successfully addressing the problem. The assimilation approach provides a broader developmental context compared to exclusively symptom, problem-, or behavior- focused approaches that typically inform outcome measurement in interpersonally based interventions. In our data, this made the difference between reflecting (APES) vs missing (Maslach Burnout Inventory, Work Environment Scale) the pre-post change that was strongly perceived by the intervention recipients. CONCLUSION: The results illustrated a working solution to the challenge of objectively evaluating progress in subjectively experienced problems. This approach informs measuring change in psychologically based interventions. PMID:24660141

This study examined concurrent and prospective associations of financial stress (financial strain, lack of financial access, public assistance) and parenting support factors (relationship quality, living at home, financial support) with young adults’ alcohol behaviors (alcohol use, heavy drinking, and problematic drinking) over a 5-year period. Analyses of National Longitudinal Study of Adolescent Health (Add Health) data (N = 7,159) showed that, over the study period, alcohol use and heavy drinking declined while problematic drinking increased. In addition, living at home and parental relationship quality were associated with fewer concurrent and prospective alcohol behaviors whereas financial strain and parents’ financial support were associated with more alcohol behaviors. The implications for minimizing alcohol misuse in young adults amid uncertain economic conditions are discussed. PMID:26388681

At-Risk/Problematic Internet Use (ARPIU) has been associated with impairment in multiple domains including psychopathology. The present study examined the relationship between ARPIU and disordered eating in a large community sample. Participants (n=1000) completed an online survey about health behaviors. Two thresholds of ARPIU and disordered eating each were examined. The ARPIU and Sub-ED (subthreshold eating disorders) groups reported greater depressive symptoms and poorer self-control than the Control group; the Sub-ED group reported greater impulsivity than the Control group. The ARPIU and Sub-ED groups significantly differed in key features related to each condition. Finally, the co-occurrence of ARPIU and Sub-ED was associated with greater depression. In the second set of analyses based on more stringent thresholds, the Problematic Internet Use (PIU) and ED groups differed on all measures compared to the Control group. The PIU and ED groups also differed on key features related to each condition, but did not differ on measures of impulsivity or self-control. The co-occurrence of PIU and ED was associated with greater depressive symptoms than either PIU or ED independently. ARPIU and Sub-ED share links to depression and poor self-control and these may represent possible therapeutic targets across Internet-use and disordered-eating behaviors. Co-occurring PIU and ED at either lenient or stringent thresholds is associated with greater depression. Future studies should examine the temporal nature of these associations and the extent to which targeting depression, Internet use, or disordered eating may lead to improvements across domains.

[Equality between men and women is a right].

PubMed

1995-07-01

Equality between men and women is one of the basic human rights. Investments in health, education, and family planning are the fundamental measures for promoting sexual equality. Promoting equality in turn is an investment in improving the health of women and children and the quality of human resources. By reducing pressure for large families, sexual equality creates conditions for faster economic growth. Women control most of the nonmonetary economy including subsistence agriculture, care of children, and domestic work, and they also play an important role in the monetary economy, although much of their work is unrecognized. The unfavorable condition of women limits their access to productive goods and social services. A strong inverse relationship exists between fertility and female education. More educated women have a greater probability of receiving prenatal care and of providing adequate care for their children. In many countries of Latin America, more than 20% of births are to adolescents. Adolescent pregnancies are often problematic, resulting in interrupted education, perpetuation of poverty, health complications, abortion, or even suicide. The problems of adolescent maternity are closely related to the inferior position of women. Education and family planning services are essential in breaking the vicious cycle. Access to employment for women contributes to reducing fertility, improves the position of women in the family, directly aids children, and reduces the woman's need to have many children for old age security. To establish conditions of equality between men and women, political actions must be taken to assure women equal social conditions and economic opportunities. Men must become more involved in family planning and in child care. The society as a whole must understand the social function of maternity.

During the last two decades, Brazilian society has gone through great changes into political, ideological and economical fields. These changes left their strings into society, specially in population health. The nurse formation based on the Law n(o) 5540/68 and on the Statement n(o) 163/72, no more meets population demands. Since 1992, the Nursing Faculty of UERJ-FEUerj intensifies the reflection movement upon teaching-learning process searching for transforming its own reality. The making of this project presents two complementary and important reasons: FEUerj docents and discents' desire in elaborating a curriculum which searches for nurses' formation that articulates teaching-work-community, theory and practice, based on a Critical Theory of Education, on the line of PROBLEMATIZATION, and the accomplishment of Statement n(o) 314/94 from the CFE and from the Letter of Order MEC n(o) 1171/15/dez/94. From debating, the professional profile has been defined from the social environment where the profession is performed and the alumnate's characteristics; area determination or group of attributions, according to professional praxis adequation, concept hierachization, processes, etc., which in the process of 'classification and syntheses' of knowledge results into a netlike chained and related tree. In the first phase of the curriculum study, it has diagnosed as principal condition, the actual curriculum 'DECONTEXTUALIZATION' and the 'US' to be faced to lead it to an end the Curriculum Reformulation Proposal. The Process of Pedagogical Abilitation for professors, workshops, researches on the desirable and present profile, seminars, performance, abilities and principles systematization, identification of areas which compose the integrated curriculum, subjects localization into areas and articulation between professional subjects and other activities, has been implemented. Based on this work on the problematized pedagogy first step, an instrument 'Research on the Professional Profile for the Nursing Graduation Course', was built, identifying the performances and principles which sustain them on each subject making the present profile clear and desirable to docents and discents.

Cellular phone use (CPU) is an important part of life for many adolescents. However, problematic CPU may complicate physiological and psychological problems. The aim of our study was to examine the associations between problematic CPU and a series of risky behaviors and low self-esteem in Taiwanese adolescents. A total of 11,111 adolescent students in Southern Taiwan were randomly selected into this study. We used the Problematic Cellular Phone Use Questionnaire to identify the adolescents with problematic CPU. Meanwhile, a series of risky behaviors and self-esteem were evaluated. Multilevel logistic regression analyses were employed to examine the associations between problematic CPU and risky behaviors and low self-esteem regarding gender and age. The results indicated that positive associations were found between problematic CPU and aggression, insomnia, smoking cigarettes, suicidal tendencies, and low self-esteem in all groups with different sexes and ages. However, gender and age differences existed in the associations between problematic CPU and suspension from school, criminal records, tattooing, short nocturnal sleep duration, unprotected sex, illicit drugs use, drinking alcohol and chewing betel nuts. There were positive associations between problematic CPU and a series of risky behaviors and low self-esteem in Taiwanese adolescents. It is worthy for parents and mental health professionals to pay attention to adolescents' problematic CPU.

The role of job satisfaction and other psychosocial variables in problematic alcohol consumption within professional settings remains understudied. The aim of this study is to assess the level of problematic alcohol consumption among male and female university professors and associated psychosocial variables. A total of 360 professors (183 men and 177 women) of a large private university in Ecuador were surveyed using standardized instruments for the following psychosocial measures: alcohol consumption, job satisfaction, psychological stress, psychological flexibility, social support and resilience. Problematic alcohol consumption was found in 13.1% of participants, although this was significantly higher (χ2 = 15.6; d.f. = 2, p < 0.001) in men (19.1%) than women (6.8%). Problematic alcohol consumption was reported in men with higher perceived stress and job satisfaction. However, 83.3% of women with problematic alcohol use reported lower job satisfaction and higher psychological inflexibility. Results suggest that job satisfaction itself did not prevent problematic alcohol consumption in men; stress was associated with problematic consumption in men and psychological inflexibility in women. Findings from this study support the need to assess aspects of alcohol consumption and problematic behavior differently among men and women. Intervention strategies aimed at preventing or reducing problematic alcohol consumption in university professors must be different for men and women. PMID:28914801

Providers treating chronic pain must attempt to relieve suffering, while minimizing problematic prescription opioid use, including addiction and diversion. Previously described risk factors for problematic use include history of substance use, younger age, male sex, psychiatric comorbidity, and lower education level. We examined these risk factors in HIV-infected individuals, using cross-sectional and longitudinal data from the Manhattan HIV Brain Bank. Problematic use was defined as illicit substance use (documented by urine toxicology or structured psychiatric interview), while receiving prescription opioids. Among 173 participants prescribed opioids, 62% had problematic use, the majority of which was discovered by urine toxicology. Problematic use was associated with past substance use, current psychiatric disorder, and poorer adherence to antiretrovirals. However, when participants without problematic use at baseline were followed longitudinally, these factors were not predictive. Furthermore, the cumulative incidence of problematic use behaviors was no greater than in a similar group of participants who were not prescribed opioids. Problematic prescription opioid use is common among HIV-infected individuals and is associated with history of substance use, current psychiatric disorder, and poor adherence to antiretrovirals. However, these factors do not predict future problematic use in those who are not currently using illicit substances, and the prescription of an opioid does not seem to predispose patients toward a future substance use disorder. Rather than attempting to assess risk for problematic prescription opioid use in HIV-infected individuals, we recommend baseline and follow-up urine toxicology.

Maladaptive cognitions predict changes in problematic gaming in highly-engaged adults: A 12-month longitudinal study.

Understanding the role of maladaptive gaming-related cognitions may assist in screening and interventions for problematic gaming, including Internet gaming disorder (IGD). Cognitive-behavioural interventions that target specific cognitions related to gaming may be more effective than more general approaches that focus only on preoccupation with games. Although past research has identified cross-sectional associations between maladaptive cognitions and problematic gaming, it is less clear whether these cognitions can predict future changes in problematic gaming behaviour. The present study employed an 18-item measure of gaming cognition, assessing perfectionism, cognitive salience, regret, and behavioural salience, to investigate potential changes in problematic gaming over a 12-month period. The sample included 465 Australian adults (84% male, M age =26.2years). It was found that individuals who became problematic gamers over 12months had higher baseline scores on perfectionism (d=1.20), cognitive salience (d=0.74) and regret (d=0.69) than those who remained non-problematic gamers. Problematic gamers who became non-problematic gamers had lower baseline perfectionism scores (d=0.62) than those who remained problematic gamers. Cognitive change accounted for an additional 28% of variance in problematic gaming scores beyond gender, age, and frequency of gaming. These findings suggest that maladaptive gaming-related cognitions could be screened in clinical trials to aid in case formulation and inform decisions on needed interventions to deliver optimal client outcomes.

The aims of this study were: (1) to examine the prevalence of symptoms of problematic cellular phone use (CPU); (2) to examine the associations between the symptoms of problematic CPU, functional impairment caused by CPU and the characteristics of CPU; (3) to establish the optimal cut-off point of the number of symptoms for functional impairment caused by CPU; and (4) to examine the association between problematic CPU and depression in adolescents. A total of 10,191 adolescent students in Southern Taiwan were recruited into this study. Participants' self-reported symptoms of problematic CPU and functional impairments caused by CPU were collected. The associations of symptoms of problematic CPU with functional impairments and with the characteristics of CPU were examined. The cut-off point of the number of symptoms for functional impairment was also determined. The association between problematic CPU and depression was examined by logistic regression analysis. The results indicated that the symptoms of problematic CPU were prevalent in adolescents. The adolescents who had any one of the symptoms of problematic CPU were more likely to report at least one dimension of functional impairment caused by CPU, called more on cellular phones, sent more text messages, or spent more time and higher fees on CPU. Having four or more symptoms of problematic CPU had the highest potential to differentiate between the adolescents with and without functional impairment caused by CPU. Adolescents who had significant depression were more likely to have four or more symptoms of problematic CPU. The results of this study may provide a basis for detecting symptoms of problematic CPU in adolescents.

Excessive alcohol intake can pose a serious problem in public health. The development of instruments to classify the consumers correctly is the first stage in the epidemiologic investigation. The internal validity and the reliability was evaluated for a test of problematic alcohol consumption (CP-alcohol) in Bucaramanga, Colombia. 2005--2006. This work provides a measure that is internally consistent and improved reliability of diagnostic technology. Six hundred one subjects between 18 and 60 years participated in the test for CP-alcohol on two occasions. At the same time, a survey on biological variables (VB), socioeconomic (VSE) and dietary (D) was administered. The internal consistency of CP-alcohol was evaluated by calculating the coefficient alpha of Cronbach, and the reliability with coefficients of Spearman and Cohens Kappa. To evaluate the associations among problematic consumption, VB, VSE, D and the risk of alcoholism, the prevalence ratios were calculated using binomial regression. The frequency of problematic alcohol consumption was of 46.9 (CI 42.9-50.9). Men presented an increased frequency of problematic alcohol use 1.6 times that of women (p<0.001). The coefficient alpha of Cronbach was moderate for all the questions of the test (minimum 0.41, maximum 0.61). In the first application of CP-alcohol, Cronbachs alpha was 0.63, and, in the second, 0.49. Spearmans correlation coefficient was of 0.87 (CI 0.84-0.90) for the population-for men 0.86 (CI 0.82-0.90) and for women 0.86 (CI 0.82-0.90). The Kappas obtained were very good, 0.70 to 0.89. Sex, pleasure provided by alcoholic drinks , risk of alcoholism according to Cut Down on Drinking, Annoyed by Criticism, Guilty Feeling, and Eye Opener (CAGE) and the quantity of consumed alcohol were all correlated with problematic consumption. CP-alcohol is a useful test for investigating the epidemiology of health problems associated with alcohol use.

Previous research underscores the importance of psychosexual guidance for adolescents with autism spectrum disorder (ASD). Such guidance is provided in the Tackling Teenage Training (TTT) program, in which adolescents with ASD receive psycho-education and practice communicative skills regarding topics related to puberty, sexuality, and intimate relationships. This randomized controlled trial investigated the effects of the TTT program on (a) cognitive outcomes (i.e. psychosexual knowledge, and insight in interpersonal boundaries) and (b) behavioral outcomes (i.e. skills needed for romantic relationships and problematic sexual behavior). A total of 189 cognitively able adolescents with ASD, aged 12-18 years old, were randomized to an intervention condition (n = 95) or a waiting-list control condition (n = 94). We assessed outcomes using self-reported as well as parent-reported questionnaires at baseline (T1), posttreatment (T2; after 6 months), and follow-up (T3; after 12 months). Linear mixed model analyses showed significant treatment effects for psychosexual knowledge and adequate insight in boundaries, both posttreatment and at follow-up. All adolescents increased significantly over time in their social responsiveness and decreased their problematic sexual behavior, irrespectively of condition. The TTT program was most effective for younger adolescents with ASD; following the TTT program resulted in higher psychosexual knowledge, and higher social functioning for these adolescents. The results of this study indicate that the TTT program is effective as a psycho-educational program to provide adolescents with ASD with the knowledge and insight they need to prepare themselves for a healthy psychosexual development. Further research is needed to investigate how this increased knowledge and insight can subsequently ameliorate improvements in romantic skills and prevent the development of problematic sexual behavior and victimization. © 2017 Association for Child and Adolescent Mental Health.

The aims of this study were to evaluate the working stability and degree of social protection of the Spanish young neurologists, and to know their opinion about their own situation. The 343 neurologists that became specialists in Spain between 2000 and 2004 were asked to participate in two consecutive surveys. The first, conducted online, included questions about the availability to change the place of work and the opinion about the situation of young neurologists, and obtained 66 answers. The second was a telephonic and online survey, answered by 217 neurologists, whose questions referred to: places of neurological education and work, type of working contract, and degree of social protection (estimated by the percentage of worked time during which they paid Social Security contributions). Sixty-three per cent (136/217) of the Spanish young neurologists had an unstable job. The most frequent unstable working contracts were: eventual (n=65; 31%), on-call contracts (n=54; 25%) and grants (n=53; 24%). Forty-eight per cent of the neurologists who ended their specialization in 2000 still remained working-unstable. The mean percentage of worked time with full social protection was 71.01+/-36.74%. Less than a half (n=101; 46%) had social protection during the entire worked time, 60 (28.6%) were socially protected during <50% of the worked time, and 23 (11%) never had social protection. A direct relationship was observed 68 between working instability and lower social protection (p=0.0002). The working situation of the Spanish young neurologists was seen as problematic by 97% of the 66 participants in the first survey. The current situation of the Spanish young neurologists, attending their working stability and degree of social protection, seems precarious and problematic. Urgent actions should be taken by the Administration to improve it.

Harmonic Resonance in Power Transmission Systems due to the Addition of Shunt Capacitors

NASA Astrophysics Data System (ADS)

Patil, Hardik U.

Shunt capacitors are often added in transmission networks at suitable locations to improve the voltage profile. In this thesis, the transmission system in Arizona is considered as a test bed. Many shunt capacitors already exist in the Arizona transmission system and more are planned to be added. Addition of these shunt capacitors may create resonance conditions in response to harmonic voltages and currents. Such resonance, if it occurs, may create problematic issues in the system. It is main objective of this thesis to identify potential problematic effects that could occur after placing new shunt capacitors at selected buses in the Arizona network. Part of the objective is to create a systematic plan for avoidance of resonance issues. For this study, a method of capacitance scan is proposed. The bus admittance matrix is used as a model of the networked transmission system. The calculations on the admittance matrix were done using Matlab. The test bed is the actual transmission system in Arizona; however, for proprietary reasons, bus names are masked in the thesis copy intended for the public domain. The admittance matrix was obtained from data using the PowerWorld Simulator after equivalencing the 2016 summer peak load (planning case). The full Western Electricity Coordinating Council (WECC) system data were used. The equivalencing procedure retains only the Arizona portion of the WECC. The capacitor scan results for single capacitor placement and multiple capacitor placement cases are presented. Problematic cases are identified in the form of 'forbidden response. The harmonic voltage impact of known sources of harmonics, mainly large scale HVDC sources, is also presented. Specific key results for the study indicated include: (1) The forbidden zones obtained as per the IEEE 519 standard indicates the bus 10 to be the most problematic bus. (2) The forbidden zones also indicate that switching values for the switched shunt capacitor (if used) at bus 3 should be should be considered carefully to avoid resonance condition from existing. (3) The highest sensitivity of 0.0033 per unit for HVDC sources of harmonics was observed at bus 7 when all the HVDC sources were active at the same time.

Application of a deconvolution method for identifying burst amplitudes and arrival times in Alcator C-Mod far SOL plasma fluctuations

NASA Astrophysics Data System (ADS)

Theodorsen, Audun; Garcia, Odd Erik; Kube, Ralph; Labombard, Brian; Terry, Jim

2017-10-01

In the far scrape-off layer (SOL), radial motion of filamentary structures leads to excess transport of particles and heat. Amplitudes and arrival times of these filaments have previously been studied by conditional averaging in single-point measurements from Langmuir Probes and Gas Puff Imaging (GPI). Conditional averaging can be problematic: the cutoff for large amplitudes is mostly chosen by convention; the conditional windows used may influence the arrival time distribution; and the amplitudes cannot be separated from a background. Previous work has shown that SOL fluctuations are well described by a stochastic model consisting of a super-position of pulses with fixed shape and randomly distributed amplitudes and arrival times. The model can be formulated as a pulse shape convolved with a train of delta pulses. By choosing a pulse shape consistent with the power spectrum of the fluctuation time series, Richardson-Lucy deconvolution can be used to recover the underlying amplitudes and arrival times of the delta pulses. We apply this technique to both L and H-mode GPI data from the Alcator C-Mod tokamak. The pulse arrival times are shown to be uncorrelated and uniformly distributed, consistent with a Poisson process, and the amplitude distribution has an exponential tail.

Research findings can change attitudes about corporal punishment.

Holden, George W; Brown, Alan S; Baldwin, Austin S; Croft Caderao, Kathryn

2014-05-01

Positive attitudes toward the use of corporal punishment (CP) predict subsequent spanking behavior. Given that CP has frequently been associated with behavior problems in children and child maltreatment, this prevention work was designed to test whether adults' attitudes could be changed by informing participants about the research findings on problematic behaviors associated with CP. Two random assignment studies are reported. In Study 1, we tested whether an active reading condition would result in more attitude change than a passive condition. With a sample of 118 non-parent adults, we found that after reading very brief research summaries on the problems associated with CP, there was a significant decrease in favorable attitudes toward CP. Contrary to expectations, the magnitude of the change was comparable for active and passive processing conditions. In Study 2, we extended our approach to a sample of 520 parents and included a control group. A significant decrease in positive attitudes toward spanking was observed in the intervention group, but no change for the control group. Parents who were unaware of the research showed more change after reading the summaries. Thus, these studies demonstrate that a brief and cost-effective approach to raise awareness of research findings can reduce positive attitudes toward CP. Implications for prevention and intervention are discussed. Copyright © 2013. Published by Elsevier Ltd.

‘Off your Face(book)’: alcohol in online social identity construction and its relation to problem drinking in university students.

PubMed

Ridout, Brad; Campbell, Andrew; Ellis, Louise

2012-01-01

Alcohol is a key component of identity exploration for many young people, yet few studies have investigated identity construction in relation to problematic drinking. Increases in youth alcohol consumption have coincided with expanding use of communications technologies, particularly social networking sites (SNS), which have altered traditional conditions of identity construction. It has been found young people often engage with alcohol in the SNS environment by portraying themselves as binge drinkers. The current study applied an innovative approach to identity construction (the photographic essay) to provide insight into the portrayal of ‘alcohol-identity’ on Facebook. One hundred and fifty-eight university students completed a range of alcohol measures before providing access for researchers to view their Facebook profiles to operationalise their alcohol-identity according to autophotographic methodology. Participants utilised a variety of photographic and textual material to present alcohol as a component of their identity on Facebook, with over half having selected an alcohol-related profile image. Alcohol-identity predicted alcohol consumption and problematic alcohol-related behaviours as measured by questionnaires used to reliably identify alcohol-related problems in university students. Almost 60% reported potentially problematic alcohol use according to the Alcohol Use Disorders Identification Test. Findings suggest that portraying oneself as a drinker is considered by many young people to be a socially desirable component of identity in the SNS environment, perpetuating an online culture that normalises binge drinking. Ready-made Facebook photo essays provide an alternate method of accessing problematic alcohol use, supplementing self-report measures.

Background and aims Gambling disorder is a significant public health concern. Especially, male minors have been shown to gamble in a problematic way, despite legal prohibitions. Methods We examined representative samples of students aged from 12 to 18 years (N = 9,309) in two German federal states to provide prevalence data and clinical description of risk factors for problematic gambling. Results We found that about 40% of the adolescents reported engaging in gambling activities within the past 12 months and found prevalence rates of 1.7% and 2.2% for problematic gambling. Especially, use of online gambling and slot machines was found to be related to problematic gambling. Male adolescents with a migration background were of higher risk for problematic gambling and psychopathological symptoms were significantly elevated among that group. Discussion The results indicate that participation in gambling activities is common among underaged adolescents and that prevalence of problematic gambling exceeds rates of adults. Similarly, problematic gambling is associated with increased psychopathological strain. Conclusion Given that a high proportion of adult gamblers report having started gambling in adolescents, our data emphasize the need for prevention and early intervention strategies for problematic gambling.

The association between problematic cellular phone use and risky behaviors and low self-esteem among Taiwanese adolescents

PubMed Central

2010-01-01

Background Cellular phone use (CPU) is an important part of life for many adolescents. However, problematic CPU may complicate physiological and psychological problems. The aim of our study was to examine the associations between problematic CPU and a series of risky behaviors and low self-esteem in Taiwanese adolescents. Methods A total of 11,111 adolescent students in Southern Taiwan were randomly selected into this study. We used the Problematic Cellular Phone Use Questionnaire to identify the adolescents with problematic CPU. Meanwhile, a series of risky behaviors and self-esteem were evaluated. Multilevel logistic regression analyses were employed to examine the associations between problematic CPU and risky behaviors and low self-esteem regarding gender and age. Results The results indicated that positive associations were found between problematic CPU and aggression, insomnia, smoking cigarettes, suicidal tendencies, and low self-esteem in all groups with different sexes and ages. However, gender and age differences existed in the associations between problematic CPU and suspension from school, criminal records, tattooing, short nocturnal sleep duration, unprotected sex, illicit drugs use, drinking alcohol and chewing betel nuts. Conclusions There were positive associations between problematic CPU and a series of risky behaviors and low self-esteem in Taiwanese adolescents. It is worthy for parents and mental health professionals to pay attention to adolescents' problematic CPU. PMID:20426807

Addictive Potential of Internet Applications and Differential Correlates of Problematic Use in Internet Gamers versus Generalized Internet Users in a Representative Sample of Adolescents.

This paper examines the addictive potential of 8 different Internet applications, distinguishing male and female users. Moreover, differential correlates of problematic use are investigated in Internet gamers (IG) and generalized Internet users (GIU). In a representative sample of 5,667 adolescents aged 12-19 years, use of Internet applications, problematic Internet use, psychopathologic symptoms (emotional problems, hyperactivity/inattention, and psychosomatic complaints), personality (conscientiousness and extraversion), psychosocial correlates (perceived stress and self-efficacy), and coping strategies were assessed. The addictive potential of Internet applications was examined in boys and girls using regression analysis. MANOVAs were conducted to examine differential correlates of problematic Internet use between IG and GIU. Chatting and social networking most strongly predicted problematic Internet use in girls, while gaming was the strongest predictor in boys. Problematic IG exhibited multiple psychosocial problems compared to non-problematic IG. In problematic Internet users, GIU reported even higher psychosocial burden and displayed dysfunctional coping strategies more frequently than gamers. The results extend previous findings on the addictive potential of Internet applications and validate the proposed distinction between specific and generalized problematic Internet use. In addition to Internet gaming disorder, future studies should also focus on other highly addictive Internet applications, that is, chatting or social networking, regarding differential correlates of problematic use. © 2017 S.

2018-01-01

In two studies, the relationship between sleep and working memory performance was investigated in children born very preterm (i.e., gestation less than 32 weeks) and the possible mechanisms underlying this relationship. In Study 1, parent-reported measures of snoring, night-time sleep quality, and daytime sleepiness were collected on 89 children born very preterm aged 6 to 7 years. The children completed a verbal working memory task, as well as measures of processing speed and verbal storage capacity. Night-time sleep quality was found to be associated with verbal working memory performance over and above the variance associated with individual differences in processing speed and storage capacity, suggesting that poor sleep may have an impact on the executive component of working memory. Snoring and daytime sleepiness were not found to be associated with working memory performance. Study 2 introduced a direct measure of executive functioning and examined whether sleep problems would differentially impact the executive functioning of children born very preterm relative to children born to term. Parent-reported sleep problems were collected on 43 children born very preterm and 48 children born to term (aged 6 to 9 years). Problematic sleep was found to adversely impact executive functioning in the very preterm group, while no effect of sleep was found in the control group. These findings implicate executive dysfunction as a possible mechanism by which problematic sleep adversely impacts upon cognition in children born very preterm, and suggest that sleep problems can increase the cognitive vulnerability already experienced by many of these children.

This study aimed to investigate the prevalence, correlates, comorbidities, and suicidal tendencies of problematic game use in a nationally representative sample of Korean adults. Of the 6022 subjects who participated in the 2011 Korean Epidemiologic Catchment Area study and completed the Composite International Diagnostic Interview 2.1, 1397 game users were evaluated for problematic game use using 9-item DSM-5 proposed criteria for Internet gaming disorder. Respondents who responded "yes" to five or more of the nine DSM-5 criteria were considered as problematic game users and the reminders were considered as normal game users. 4.0% (56/1397) of game users were classified as a problematic game user. Problematic game users were more likely to be in younger age group and live in urban area compared with normal game user. Problematic game use was positively associated with several psychiatric disorders including nicotine use disorder, depressive disorder, and anxiety disorder, but not associated with alcohol use disorder and obsessive-compulsive disorder, after adjusting for age, sex, and residential area. Problematic game use was significantly and positively associated with suicide plans, after controlling for psychiatric disorders as well as socio-demographic factors. Problematic game use is relatively prevalent in Korean adult population and highly comorbid with other psychiatric disorders and suicidality. Therefore, preventive strategy for problematic game use is needed for game users who were more likely to be addicted such as young adults in urban area, and mental health screening and appropriate treatment are needed for individuals with problematic game use.

Although self-esteem is related to problematic drinking, the mechanisms by which it affects drinking remain unclear. The purpose of this study was to determine whether coping mechanisms mediate the relationship between self-esteem and problematic drinking among Chinese men and women with alcohol use disorders and to recommend appropriate interventions for drinking problems. A cross-sectional survey was conducted in Harbin, Heilongjiang Province, China. A sample of 5,689 community residents was screened, and 517 male and 172 female problematic drinkers were chosen to participate in this study. A self-esteem scale, a coping questionnaire and an alcohol use disorder identification test were completed in order to assess participants' self-esteem, coping mechanisms and alcohol use disorders, respectively. Participants' socio-demographic data were also gathered at this stage. The resulting data were examined via descriptive statistics, correlations and bootstrap analyses. Lower self-esteem levels were related to problematic drinking, and there were no gender differences in the relationship between self-esteem and problematic drinking. A relationship between low self-esteem and negative coping was observed only in men. Negative coping thus mediated the relationship between self-esteem and problematic drinking among men, but this was not the case for women. Positive coping did not mediate the relationship between self-esteem and problematic drinking among the participants, regardless of gender. Self-esteem and coping strategies are correlated among problematic drinkers. In addition, there are gender differences in the manners in which negative coping mediates the relationship between self-esteem and problematic drinking. Problematic drinking interventions directed at males should simultaneously address low self-esteem and negative coping.

Depression and problematic alcohol use represent two of the major causes of disease burden in young adults. These conditions frequently co-occur and this is associated with increased harm and poorer outcomes than either disorder in isolation. Integrated treatments have been shown to be effective; however, there remains a significant gap between those in need of treatment and those receiving it. The increased availability of eHealth programs presents a unique opportunity to treat these conditions. This study aimed to evaluate the feasibility and preliminary efficacy of an automated Web-based self-help intervention (DEAL Project) in treating co-occurring depressive symptoms and problematic alcohol use in young people. Young people (aged 18 to 25 years) with moderate depression symptoms and drinking at hazardous levels (recruited largely via social media) were randomly allocated to the DEAL Project (n=60) or a Web-based attention-control condition (HealthWatch; n=44). The trial consisted of a 4-week intervention phase with follow-up assessment at posttreatment and at 3 and 6 months postbaseline. The primary outcomes were change in depression severity according to the Patient Health Questionnaire-9 as well as quantity and frequency of alcohol use (TOT-AL). The DEAL Project was associated with statistically significant improvement in depression symptom severity (d=0.71) and reductions in alcohol use quantity (d=0.99) and frequency (d=0.76) in the short term compared to the control group. At 6-month follow-up, the improvements in the intervention group were maintained; however, the differences between the intervention and control groups were no longer statistically significant, such that between-group effects were in the small to moderate range at 6 months (depression symptoms: d=0.39; alcohol quantity: d=-0.09; alcohol frequency: d=0.24). Overall, the DEAL Project was associated with more rapid improvement in both depression symptoms and alcohol use outcomes in young people with these co-occurring conditions relative to an attention-control condition. However, long-term outcomes are less clear.

Problematic game play: the diagnostic value of playing motives, passion, and playing time in men.

PubMed

Kneer, Julia; Rieger, Diana

2015-04-30

Internet gaming disorder is currently listed in the DSM-not in order to diagnose such a disorder but to encourage research to investigate this phenomenon. Even whether it is still questionable if Internet Gaming Disorder exists and can be judged as a form of addiction, problematic game play is already very well researched to cause problems in daily life. Approaches trying to predict problematic tendencies in digital game play have mainly focused on playing time as a diagnostic criterion. However, motives to engage in digital game play and obsessive passion for game play have also been found to predict problematic game play but have not yet been investigated together. The present study aims at (1) analyzing if obsessive passion can be distinguished from problematic game play as separate concepts, and (2) testing motives of game play, passion, and playing time for their predictive values for problematic tendencies. We found (N = 99 males, Age: M = 22.80, SD = 3.81) that obsessive passion can be conceptually separated from problematic game play. In addition, the results suggest that compared to solely playing time immersion as playing motive and obsessive passion have added predictive value for problematic game play. The implications focus on broadening the criteria in order to diagnose problematic playing.

Managing organisational change: the "gendered" organisation of space and time.

PubMed

Goetz, A M

1997-02-01

Although the Bangladesh Rural Advancement Committee (BRAC) maintains a strong commitment to gender equity in its anti-poverty programs, a conservative external environment often impedes efforts to make its organizational structure consistent with this commitment. For example, BRAC's approach to organizing its field operations has been to abolish the distinction between home and office. BRAC's female employees live with male colleagues in their rural offices, travel long distances on bicycles and motorcycles, and reject the sari--practices that are antithetical to the prevailing culture and place tremendous pressure on these field workers. The high work intensity, need to work beyond normal business hours, and lack of on-site child care subjects married female employees to hostility from their husbands and relatives. Single female employees are often regarded as unmarriagable because of their divergent life-styles. Although BRAC makes provisions for employees to take leave for family responsibilities, staff who access this benefit are viewed as more committed to family than their work. The sexual activities of female--but not male--employees are scrutinized. Despite these contradictions, BRAC's innovative arrangements model a new form of gender relations in rural areas. BRAC is enabling its young women employees to postpone marriage and demonstrate a nontraditional role. The extent to which BRAC should take responsibility for compensating for the constraints imposed on women by patriarchy remains problematic. Working conditions could be improved, however, by allowing women to be near their families, domesticating the work environment, and respecting women's personal lives.

Risk Factors for Problematic Behaviors among Forensic Outpatients under the Medical Treatment and Supervision Act in Japan

Ando, Kumiko; Soshi, Takahiro; Nakazawa, Kanako; Noda, Takamasa; Okada, Takayuki

2016-01-01

The Medical Treatment and Supervision Act (MTSA) was enacted in 2005 in Japan to promote the reintegration of clinical offenders with mental disorders into society. Under the MTSA, individuals who committed serious crimes in a state of insanity or diminished responsibility are diverted from the criminal justice system to the mental health system. Based on court decisions about MTSA-based treatment, clinical offenders have an obligation to engage in rehabilitation within their local community under the guidance of mental health professionals. However, patients under MTSA-based clinical treatments have faced various problems in the course of treatment, because of psychiatric as well as other static or dynamic factors, and sometimes have committed problematic behaviors, such as violence and medical non-compliance. Hence, this study aimed to clarify factors related to patients’ inclusion in MTSA-based outpatient treatment and additionally, their commitment of problematic behaviors, based on confidential data acquired during a four-year government survey period (National Center of Neurology and Psychiatry) from MTSA enactment (July 15, 2005) to December 31, 2009. In total, we recruited 441 clinical offenders receiving MTSA-based outpatient treatment from 158 nationwide facilities. To evaluate related factors, we collected demographic, psychiatric, forensic, clinical treatment, and social service information. Statistical analyses demonstrated that predominant profiles of patients included male gender, younger age, low school history, psychiatric diagnoses (F1, F2, and F3), and no correctional or outpatient history before MTSA-based treatment. F1 or substance use diagnosis, in particular, was increasingly correlated with other factors, such as male gender, older age, and correctional history before MTSA treatment. Among the 441 patients, 189 (43%) committed problematic behaviors in the course of the MTSA-based outpatient treatment. Risk factors for patients’ commitment of problematic behaviors comprised F1 diagnosis and inpatient history before MTSA-based treatment inclusion. In summary, reduction of overall problematic behaviors under the MTSA outpatient likely makes progress by focal attention to patients with psychiatric disorders caused by substance use and/or a past inpatient history for more severe psychiatric symptoms. This work is of ongoing and future importance in the domain of forensic community treatment, to connect risk-enhancing factors with risk management. PMID:27605915

Exploring Associations between Problematic Internet Use, Depressive Symptoms and Sleep Disturbance among Southern Chinese Adolescents.

Tan, Yafei; Chen, Ying; Lu, Yaogui; Li, Liping

2016-03-14

The primary aim of this study was to examine associations between problematic Internet use, depression and sleep disturbance, and explore whether there were differential effects of problematic Internet use and depression on sleep disturbance. A total of 1772 adolescents who participated in the Shantou Adolescent Mental Health Survey were recruited in 2012 in Shantou, China. The Chinese version of the Internet Addiction Test (IAT) was used to evaluate the prevalence and severity of Internet addiction. The Chinese version of the Pittsburgh Sleep Quality Index (PSQI), a 10-item version of the Center for Epidemiologic Studies Depression Scale (CESD-10), and other socio-demographic measures were also completed. Multiple regression analysis was used to test the mediating effect of problematic Internet use and depression on sleep disturbance. Among the participants, 17.2% of adolescents met the criteria for problematic Internet use, 40.0% were also classified as suffering from sleep disturbance, and 54.4% of students had depressive symptoms. Problematic Internet use was significantly associated with depressive symptoms and sleep disturbance. The correlation between depressive symptoms and sleep disturbance was highly significant. Both problematic Internet use (β = 0.014; Sobel test Z = 12.7, p < 0.001) and depression (β = 0.232; Sobel test Z = 3.39, p < 0.001) had partially mediating effects on sleep disturbance and depression was of greater importance for sleep disturbance than problematic Internet use. There is a high prevalence of problematic Internet use, depression and sleep disturbance among high school students in southern China, and problematic Internet use and depressive symptoms are strongly associated with sleep disturbance. This study provides evidence that problematic Internet use and depression have partially mediating effects on sleep disturbance. These results are important for clinicians and policy makers with useful information for prevention and intervention efforts.

The aim of this study was to investigate the relationship between problematic internet use and eating attitudes in a group of university students. The study sample consisted of 314 students attending programs at the faculties of education, medicine and communications at the Karadeniz Technical University in Turkey. One hundred forty-seven (46.8 %) were male and 167 (53.2 %) female. The Problematic Internet Use Scale was used to measure problematic internet use levels among university students and the Eating Attitudes Test to determine anorexia nervosa symptoms. Additionally, a Personal Data Form was used to determine age, gender, faculty attended and computer ownership. Data were analyzed on SPSS 15.00. Pearson's product moments correlation coefficient, multiple linear regression analysis, the independent t test and one-way ANOVA were used for data analysis. The research findings showed that 46.8 % of students were female and 53.2 % male. Mean age was 20.65 (SD 1.42). Analysis showed a significant positive correlation between problematic internet use and eating attitudes (r = 0.77, p < 0.01). Problematic internet use was found to be a significant predictor of eating attitudes. The results also showed a significant difference in problematic internet use with regard to program variables [F (2,311) = 102.79]. There were no significant differences in problematic internet use in terms of gender or computer ownership. The results of this study indicate that problematic internet use is significantly correlated with eating disorders, that problematic internet use does not vary on the basis of gender or computer ownership and that variations arise in problematic internet use depending on the faculty attended.

Background Although self-esteem is related to problematic drinking, the mechanisms by which it affects drinking remain unclear. The purpose of this study was to determine whether coping mechanisms mediate the relationship between self-esteem and problematic drinking among Chinese men and women with alcohol use disorders and to recommend appropriate interventions for drinking problems. Methods A cross-sectional survey was conducted in Harbin, Heilongjiang Province, China. A sample of 5,689 community residents was screened, and 517 male and 172 female problematic drinkers were chosen to participate in this study. A self-esteem scale, a coping questionnaire and an alcohol use disorder identification test were completed in order to assess participants’ self-esteem, coping mechanisms and alcohol use disorders, respectively. Participants’ socio-demographic data were also gathered at this stage. The resulting data were examined via descriptive statistics, correlations and bootstrap analyses. Results Lower self-esteem levels were related to problematic drinking, and there were no gender differences in the relationship between self-esteem and problematic drinking. A relationship between low self-esteem and negative coping was observed only in men. Negative coping thus mediated the relationship between self-esteem and problematic drinking among men, but this was not the case for women. Positive coping did not mediate the relationship between self-esteem and problematic drinking among the participants, regardless of gender. Conclusions Self-esteem and coping strategies are correlated among problematic drinkers. In addition, there are gender differences in the manners in which negative coping mediates the relationship between self-esteem and problematic drinking. Problematic drinking interventions directed at males should simultaneously address low self-esteem and negative coping. PMID:26451595

Problematic Exercise in Anorexia Nervosa: Testing Potential Risk Factors against Different Definitions.

Rizk, Melissa; Lalanne, Christophe; Berthoz, Sylvie; Kern, Laurence; Godart, Nathalie

2015-01-01

"Hyperactivity" has a wide prevalence range of 31% to 80% in the anorexia nervosa literature that could be partly due to the plethora of definitions provided by researchers in this field. The purpose of this study was two-fold: 1) To assess the variance across prevalence rates of problematic exercise encountered in patients with anorexia nervosa, in relation to seven different definitions found in the literature. 2) To examine how core eating disorder symptoms and the dimensions of emotional profile are associated with these different definitions and the impact of these definitions on the assessment of patients' quality of life. Exercise was evaluated in terms of duration, intensity, type and compulsion using a semi-structured questionnaire administered to 180 women suffering from severe anorexia nervosa. Seven different definitions of problematic exercise were identified in the literature: three entailing a single dimension of problematic exercise (duration, compulsion or intensity) and four combining these different dimensions. Emotional profile scores, obsessive-compulsive symptoms, eating disorder symptomatology, worries and concerns about body shape, self-esteem and quality of life were assessed using several established questionnaires. The prevalence of problematic exercise varied considerably from, 5% to 54%, depending on the number of criteria used for its definition. The type and level of eating disorder symptomatology was found to be associated with several definitions of problematic exercise. Surprisingly, a better self-reported quality of life was found among problematic exercisers compared to non-problematic exercisers in three of the definitions. The different definitions of problematic exercise explain the broad prevalence ranges and the conflicting associations generally reported in the literature between problematic exercise and eating disorder-related psychological parameters. There is an urgent need for a valid consensus on the definition of problematic exercise in anorexia nervosa. This will support the development of further research on the etiology and treatment of problematic exercise.

Should gratitude be a requirement for access to live organ donation?

PubMed

Escher, Monica; Lamuela-Naulin, Monique; Bollondi, Catherine; Flores Menendez, Paola; Hurst, Samia A

2017-11-01

Gratitude is both expected and problematic in live organ donation. Are there grounds to require it, and to forbid access to live donor transplantation to a recipient who fails to signal that he feels any form of gratitude? Recipient gratitude is not currently required for organ donation, but it is expected and may be a moral requirement. Despite this, we argue that making it a condition for live organ transplantation would be unjustified. It would constitute a problematic and disproportionate punishment for perceived immoral behaviour on the part of the recipient. It would also bar the donor from positive aspects of organ donation that remain even in the absence of recipient gratitude. A potential recipient's lack of gratitude should be explored as a possible symptom of other morally problematic issues and integrated into the information provided to the potential donor. Recognition of the donor's gift and gratitude for it may also need to be expressed in part by others. This last aspect is relevant even in cases where the recipient feels and expresses gratitude.

Do numerical rating scales and the Roland-Morris Disability Questionnaire capture changes that are meaningful to patients with persistent back pain?

PubMed

Hush, Julia M; Refshauge, Kathryn M; Sullivan, Gerard; De Souza, Lorraine; McAuley, James H

2010-07-01

To investigate patients' views about two common outcome measures used for back pain: Numerical Rating Scales for pain and the Roland-Morris Disability Questionnaire. Thirty-six working adults who had previously sought primary care for back pain and who could speak and read English. Eight focus groups were conducted to explore participants' views about the 11-point Numerical Rating Scales and the 24-item Roland-Morris Disability Questionnaire. Each group was led by a facilitator and an interview topic guide was used. Audio recordings of focus groups were transcribed verbatim. Framework analysis was used to chart participants' views and an interpretive analysis performed to explain the findings. Participants reported that neither the Roland-Morris nor the Numerical Rating Scales captured the complex personal experience of pain or relevant changes in their condition. The time-frame of assessment was identified as particularly problematic and the Roland-Morris did not capture relevant functional domains. This study provides empirical data that working adults with persistent back pain consider these clinical outcome measures largely inadequate. These measures currently used for back pain may contribute to misleading conclusions about treatment efficacy and patient recovery.

Mapping HIV community viral load: space, power and the government of bodies

HIV plasma viral load testing has become more than just a clinical tool to monitor treatment response at the individual level. Increasingly, individual HIV plasma viral load testing is being reported to public health agencies and is used to inform epidemiological surveillance and monitor the presence of the virus collectively using techniques to measure ‘community viral load’. This article seeks to formulate a critique and propose a novel way of theorizing community viral load. Based on the salient work of Michel Foucault, especially the governmentality literature, this article critically examines the use of community viral load as a new strategy of government. Drawing also on the work of Miller and Rose, this article explores the deployment of ‘community’ through the re-configuration of space, the problematization of viral concentrations in specific microlocales, and the government (in the Foucauldian sense) of specific bodies which are seen as ‘risky’, dangerous and therefore, in need of attention. It also examines community viral load as a necessary precondition — forming the ‘conditions of possibility’ — for the recent shift to high impact prevention tactics that are being scaled up across North America.

Large-scale treatment studies suggest that effective depression treatment and reduced depression are associated with improved substance use outcomes. Yet information is limited regarding the longitudinal association between depressive symptoms and problematic substance use and its predictors, particularly in real-world practice settings. Using latent growth modeling, we examined the (a) longitudinal association between depressive symptoms and problematic substance use, (b) impact of depressive symptoms on problematic substance use, (c) impact of problematic substance use on depressive symptoms, and (d) role of co-occurring symptoms on depression and problematic substance use. Participants were part of the Youth Partners in Care study, an effectiveness trial evaluating a quality improvement intervention for youth depression through primary care. This ethnically diverse sample included youths aged 13 to 21 years screening positive for depression from 5 health care organizations. Participants were followed 4 times over an 18-month period and assessed for both depressive symptoms and problematic substance use. Both depressive symptoms and problematic substance use declined over time. Higher baseline depressive symptoms predicted a slower decline in problematic substance use, but baseline problematic substance use did not predict changes in depressive symptoms. These prospective associations remained robust controlling for co-occurring symptoms. Results support prior large-scale depression studies indicating depression burden negatively impacts substance use outcome and extends these findings to real-world practice settings. Findings underscore the importance of addressing depression severity in youth with concurrent substance use problems, even in the context of comorbid symptoms of anxiety, delinquency, and aggression.

Suicidal ideation and attempt among adolescents are risk factors for eventual completed suicide. Cellular phone use (CPU) has markedly changed the everyday lives of adolescents. Issues about how cellular phone use relates to adolescent mental health, such as suicidal ideation and attempts, are important because of the high rate of cellular phone usage among children in that age group. This study explored the association between problematic CPU and suicidal ideation and attempts among adolescents and investigated how family function and depression influence the association between problematic CPU and suicidal ideation and attempts. A total of 5051 (2872 girls and 2179 boys) adolescents who owned at least one cellular phone completed the research questionnaires. We collected data on participants' CPU and suicidal behavior (ideation and attempts) during the past month as well as information on family function and history of depression. Five hundred thirty-two adolescents (10.54%) had problematic CPU. The rates of suicidal ideation were 23.50% and 11.76% in adolescents with problematic CPU and without problematic CPU, respectively. The rates of suicidal attempts in both groups were 13.70% and 5.45%, respectively. Family function, but not depression, had a moderating effect on the association between problematic CPU and suicidal ideation and attempt. This study highlights the association between problematic CPU and suicidal ideation as well as attempts and indicates that good family function may have a more significant role on reducing the risks of suicidal ideation and attempts in adolescents with problematic CPU than in those without problematic CPU. © 2014.

Given the prevalence of Internet use among youth, there is concern that a subset of Internet-using youth may exhibit problematic or addictive patterns of Internet use. The present study examines the association between problematic Internet use (PIU), demographic variables, and health-related measures among Chinese adolescents. Survey data from 1552 adolescents (male = 653, mean age = 15.43 years) from Jilin Province, China, were collected. According to the Young Diagnostic Questionnaire for Internet Addiction (YDQ), 77.8% (n=1,207), 16.8% (n=260), and 5.5% (n=85) showed adaptive, maladaptive, and problematic Internet use, respectively. Multinomial logistic regression analysis revealed that gender and family income per month differed between youth showing problematic and adaptive patterns of Internet use. Well-being, self-esteem, and self-control were related to severity of problematic Internet use, with greater severity typically associated with poorer measures in each domain. The findings that severity of problematic Internet use is associated with specific socio-demographic features and temperamental and well-being measures suggest that specific groups of youth may be particularly vulnerable to developing problematic Internet use. Early prevention/intervention programs targeting at-risk groups may help improve public health. PMID:27249805

Latent-level relations between DSM-5 PTSD symptom clusters and problematic smartphone use.

Common mental health consequences following the experience of potentially traumatic events include Posttraumatic Stress Disorder (PTSD) and addictive behaviors. Problematic smartphone use is a newer manifestation of addictive behaviors. People with anxiety severity (such as PTSD) may be at risk for problematic smartphone use as a means of coping with their symptoms. Unique to our knowledge, we assessed relations between PTSD symptom clusters and problematic smartphone use. Participants ( N = 347), recruited through Amazon's Mechanical Turk (MTurk), completed measures of PTSD and smartphone addiction. Results of the Wald tests of parameter constraints indicated that problematic smartphone use was more related to PTSD's negative alterations in cognitions and mood (NACM) than to PTSD's avoidance factor, Wald χ 2 (1, N = 347) = 12.51, p = 0.0004; and more to PTSD's arousal compared to PTSD's avoidance factor, Wald χ 2 (1, N = 347) = 14.89, p = 0.0001. Results indicate that problematic smartphone use is most associated with negative affect and arousal among trauma-exposed individuals. Implications include the need to clinically assess problematic smartphone use among trauma-exposed individuals presenting with higher NACM and arousal severity; and targeting NACM and arousal symptoms to mitigate the effects of problematic smartphone use.

Recently, quantum adiabatic computation has attracted more and more attention in the literature. It is a novel quantum computation model based on adiabatic approximation, and the analysis of a quantum adiabatic algorithm depends highly on the adiabatic conditions. However, it has been pointed out that the traditional adiabatic conditions are problematic. Thus, results obtained previously should be checked and sufficient adiabatic conditions applicable to adiabatic computation should be proposed. Based on a result of Tong et al. [Phys. Rev. Lett. 98, 150402 (2007)], we propose a modified adiabatic criterion which is more applicable to the analysis of adiabatic algorithms. Asmore » an example, we prove the validity of the local adiabatic search algorithm by employing our criterion.« less

Despite the increased social acceptance and widespread use of pornography over the past few decades, reliable and valid instruments assessing problematic use of pornography are lacking. This paper reports the findings of three studies aimed at developing and validating a new scale measuring problematic pornography use. The Problematic Pornography Use Scale (PPUS) items showed high internal consistency, convergent validity, and construct validity. Exploratory and confirmatory factor analyses revealed four core factors relating to proposed domains of problematic pornography use. High PPUS scores were positively correlated with measures of psychopathology, low self-esteem and poor attachment. Although PPUS scores were related to other behavioral addictions, problematic pornography use as operationalized in the current paper appears to be uniquely distinguished from features of behavioral addictions relating to gambling and Internet use. Findings highlight the potential use of the PPUS for future research and possible clinical applications by defining problematic pornography use as a behavioral addiction.

Nomophobia is the fear of being out of mobile phone contact. People suffering from this anxiety disorder have feelings of stress and nervousness when access to their mobiles or computers is not possible. This work is an adaptation and validation study of the Spanish version of the Nomophobia Questionnaire (NMP-Q). The study included 306 students (46.1% males and 53.9% females) with ages ranging 13 to 19 years (Md=15.41±1.22). Exploratory factor analysis revealed four dimensions that accounted for 64.4% of total variance. The ordinal α-value was 0.95, ranging from 0.75 to 0.92 across factors. Measure of stability was calculated by the testretest method (r=0.823). Indicators of convergence with the Spanish versions of the “Mobile Phone Problem Use Scale” (r=0.654) and the “Generalized Problematic Internet Use Scale” (r=0.531) were identified. Problematic mobile phone use patterns were examined taking the 15P, 80P and 95P percentiles as cut-off points. Scores of 39, 87 and 116 on NMP-Q corresponded to occasional, at-risk and problematic users, respectively. Psychometric analysis shows that the Spanish version of the NMP-Q is a valid and reliable tool for the study of nomophobia.

This study was done to compare factors influencing children's self-esteem between two parent families and single parent families. The participants were 692 children aged 11 to 13 yr (388 in two parent families and 304 in single parent families) recruited from 20 community agencies and 5 elementary schools in Gyeonggi Province and Seoul City, South Korea. Data were collected from May to July, 2007 using a survey questionnaire containing items on self-esteem, internal control, problematic behavior, school record, family hardiness, parent-child communication and social support. The data were analyzed using SPSS 15.0 program and factors affecting children's self-esteem were analyzed by stepwise multiple regression. Scores for the study variables were significantly different between the two groups. The factors influencing children's self-esteem were also different according to family type. For two parent families, internal control, problematic behavior, school record, and parent-child communication significantly predicted the level of self-esteem (adjusted R(2)=.505, p<.001). For single parent families, social support, family hardiness, internal control, problematic behavior, school record, and parent-child communication significantly predicted the level of self-esteem (adjusted R(2)=.444, p<.001). Nurse working with children should consider family type-specific factors influencing their self-esteem.

'It is only a pinprick': (or is it?): childhood vaccinations in general practice as 'matter out of place'.

PubMed

Elverdam, Beth

2011-12-01

The analysis presented in this paper is part of a larger study, the aim of which is to describe the GPs' everyday taken-for-granted working life. The study is based on multi-sited anthropological fieldwork in Danish general practices. This paper analyses consultations where children are vaccinated and the analysis shows the way these consultations differ from other consultations in relation to flow and communication. Neither parents nor doctors question the value of the vaccination, but the manner in which they talk about it and handle it in the flow of the consultation points to them experiencing it as being problematic. Taking inspiration from Mary Douglas' theory on cultural classification the injection is interpreted as 'matter out of place'. The analysis identifies the infliction of pain and the discomfort this brings to the doctor and the parent as problematic as well as a breach of the doctor-patient relationship. The aim of vaccination is to prevent potential diseases in the future, but its function in the consultation, besides being fulfilment of national guidelines, is not immediately apparent. It has no real function in the consultation and this makes it problematic in the present, causing the ambiguity that both doctors and parents express.

Differentiating children with and without a history of repeated problematic sexual behavior.

Many adolescents who sexually offend commenced problematic sexual behaviors as children. There is little evidence to indicate which children may be at risk to continue problematic sexual behaviors and which children will desist once identified. The goal of this study was to determine variables that differentiate children who repeated problematic sexual behaviors following adult reprimand from those who did not. Predictive accuracy of 33 risk variables was investigated using 62 children assessed for problematic sexual behaviors. Eight individual variables were related to group membership, and a total score based on the combination of these variables was predictive of group membership. The results indicate variables that may assist in identifying children requiring intervention versus those likely to discontinue problematic sexual behaviors once they are identified and reprimanded.

Adaptive Control Using Residual Mode Filters Applied to Wind Turbines

Frost, Susan A.; Balas, Mark J.

2011-01-01

Many dynamic systems containing a large number of modes can benefit from adaptive control techniques, which are well suited to applications that have unknown parameters and poorly known operating conditions. In this paper, we focus on a model reference direct adaptive control approach that has been extended to handle adaptive rejection of persistent disturbances. We extend this adaptive control theory to accommodate problematic modal subsystems of a plant that inhibit the adaptive controller by causing the open-loop plant to be non-minimum phase. We will augment the adaptive controller using a Residual Mode Filter (RMF) to compensate for problematic modal subsystems, thereby allowing the system to satisfy the requirements for the adaptive controller to have guaranteed convergence and bounded gains. We apply these theoretical results to design an adaptive collective pitch controller for a high-fidelity simulation of a utility-scale, variable-speed wind turbine that has minimum phase zeros.

Exploring Associations between Problematic Internet Use, Depressive Symptoms and Sleep Disturbance among Southern Chinese Adolescents

2016-01-01

The primary aim of this study was to examine associations between problematic Internet use, depression and sleep disturbance, and explore whether there were differential effects of problematic Internet use and depression on sleep disturbance. A total of 1772 adolescents who participated in the Shantou Adolescent Mental Health Survey were recruited in 2012 in Shantou, China. The Chinese version of the Internet Addiction Test (IAT) was used to evaluate the prevalence and severity of Internet addiction. The Chinese version of the Pittsburgh Sleep Quality Index (PSQI), a 10-item version of the Center for Epidemiologic Studies Depression Scale (CESD-10), and other socio-demographic measures were also completed. Multiple regression analysis was used to test the mediating effect of problematic Internet use and depression on sleep disturbance. Among the participants, 17.2% of adolescents met the criteria for problematic Internet use, 40.0% were also classified as suffering from sleep disturbance, and 54.4% of students had depressive symptoms. Problematic Internet use was significantly associated with depressive symptoms and sleep disturbance. The correlation between depressive symptoms and sleep disturbance was highly significant. Both problematic Internet use (β = 0.014; Sobel test Z = 12.7, p < 0.001) and depression (β = 0.232; Sobel test Z = 3.39, p < 0.001) had partially mediating effects on sleep disturbance and depression was of greater importance for sleep disturbance than problematic Internet use. There is a high prevalence of problematic Internet use, depression and sleep disturbance among high school students in southern China, and problematic Internet use and depressive symptoms are strongly associated with sleep disturbance. This study provides evidence that problematic Internet use and depression have partially mediating effects on sleep disturbance. These results are important for clinicians and policy makers with useful information for prevention and intervention efforts. PMID:26985900

Correlates of problematic gaming - Is there support for proneness to risky behaviour?

2017-09-01

This paper explores problematic Internet gaming in the context of other forms of risky behaviour. The basic premise is that children and adolescents at risk will display different types of risky behaviour in various settings. Children and adolescents (N=1150) were surveyed about (cyber)violence, problematic gaming (habits, motives and symptoms), self-disclosure via Facebook and self-esteem. Regular gamers were more violent both face-to-face and via the Internet, and were more prone to problematic gaming than occasional gamers. Those who played games for more than five hours per day (9% of respondents) were classified as potentially problematic gamers. They experienced and committed more violence both face-to-face and via the Internet, were more involved in self-disclosure and had more problematic gaming symptoms than those who played for less than five hours a day, but these groups did not differ in self-esteem. Participants could choose from a list of eight different motives for their gaming; those motivated by peer communication, a sense of control, relaxation, conformism, self-efficacy and to distract from problems reported more symptoms of problematic gaming than those not motivated by these factors. Gender, age, self-esteem, self-disclosure and committing violence contributed to explaining the variance in problematic gaming, accounting for about 26% of its variance. Boys, lower self-esteem, more self-disclosure and committing both types of violence more regularly were connected with reporting more symptoms of problematic gaming. The results will be discussed in the context of a general proneness to risky behaviour. Committing violence against peers (both traditional and cyber) predicts significantly problematic gaming. This supports the premise that children and adolescents at risk are prone to exhibiting different forms of risky behaviour in different settings.

Problematic use of social network sites: the interactive relationship between gratifications sought and privacy concerns.

PubMed

Chen, Hsuan-Ting; Kim, Yonghwan

2013-11-01

Problematic Internet use has long been a matter of concern; however, few studies extend this line of research from general Internet use to the use of social network sites (SNSs), or explicate the problematic use of SNSs by understanding what factors may enhance or reduce users' compulsive behaviors and excessive form of use on SNSs. Building on literature that found a positive relationship between gratifications sought from the Internet and problematic Internet use, this study first explores the types of gratifications sought from SNSs and examines their relationship with problematic SNS use. It found that three types of gratifications-diversion, self-presentation, and relationship building-were positively related to problematic SNS use. In addition, with a growing body of research on SNS privacy, a moderating role of privacy concerns on SNSs has been proposed to understand how it can influence the relationship between gratifications sought from SNSs and problematic SNS use. The findings suggest that different subdimensions of privacy concerns interact with gratifications sought in different manners. In other words, privacy concerns, including unauthorized secondary use and improper access, play a more influential role in constraining the positive relationship between gratifications sought and problematic SNS use when individuals seek to build relationships on SNSs. However, if individuals seek to have diversion on SNSs, their privacy concerns will be overridden by their gratifications sought, which in turn leads to problematic SNS use. Implications of these findings for future research are discussed.

Background and aims: Likening mobile phone use dependency to the classification of excessive behaviors may be necessarily equivalent in seriousness to previously established addictions such as problematic computing or excessive gambling. The aim of the study explores into the behavior of excessive use of mobile phones as a pathological behavior. Methods: Two studies investigated criteria for problematic mobile phone usage by examining student (Study 1, N = 301) and nonstudent (Study 2, N = 362) responses to a set of adapted mobile phone addiction inventories. Study 1 investigated cell phone addiction inventories as constructs designed to measure problematic cell phone use. Additionally, Study 2 sought to predict age, depression, extraversion, emotional stability, impulse control, and self-esteem as independent variables that augment respondents’ perceptions of problematic use. Results: The results from Study 1 and Study 2 indicate that 10 to 25% of the participants tested exhibited problematic cell phone usage. Additionally, age, depression, extraversion, and low impulse control are the most suitable predictors for problematic use. Conclusions: The results of the two studies indicate that problematic mobile phone use does occur and ought to be taken seriously by the psychological community. Presently, there is limited data providing conclusive evidence for a comprehensible categorization of cell phone addiction, as well as a unified explanatory model specific to problematic mobile phone use. Studies such as this one may contribute substantial findings, adding scientific significance, and offering a valuable submission for the ongoing progress of creating intervention frameworks relative to “virtual addictions”.

2008-03-01

According to recent studies, intercultural interaction in health care between clients and care-givers seems to be problematic. A recent Swedish study revealed that a majority of Primary Child Health Care Nurses (PCHNurses) experienced difficulties in their interaction with children and parents of foreign origin. As every third child in the Primary Child Heath Care (PCHC) services is of foreign origin it seem to be of utmost importance to examine in depth how these difficulties could be understood and explained. The present study aimed at a theoretical explanation of the core problem concerning PCHNurses' interaction with children and parents of foreign origin, as experienced by the PCHNurses. Fifteen PCHNurses working in the PCHC services were interviewed. Grounded Theory was used as research methodology because focus is on social interactions and the aim is to theoretically explain unarticulated social processes. Anxiety about missing children, exposed to risks of ill-health, due to various conditions in the child's home environment, turned out to be the PCHNurses' main concern. An assessment of health risks was initiated, when PCHNurses thought that psychosocial conditions in the child's environment might cause ill health. Some of the psychosocial conditions were difficult to assess, as they were unfamiliar and not understood by the PCHNurses. In such difficult-to-assess cases, when the PCHNurses considered the possibility of undefined risk to the child's health they held on to the assessment of the cases and worked out strategies to learn and understand more about the child and the child's home environment. A theoretical model grounded in data was created accounting for the variation in the assessment process and the different strategies used. Implications are discussed and recommendations for improvements are given.

[War on Drugs or War against Health? The pitfalls for public health of Puerto Rican drug policy].

PubMed

Santiago-Negrón, Salvador; Albizu-García, Carmen E

2003-03-01

Puerto Rico has followed the United States in adopting drug policy sustained on a criminal justice model that limits the opportunities to address problematic drug use through public health interventions. Demand for illegal drugs is controlled by criminalizing drug use and applying jail sentences for drug offenses. These strategies marginalize drug users and reduce opportunities to minimize health risks applying public health measures. Production and sale of illegal drugs is criminalized with the intent of dissuading drug use, with adverse unintended health effects that impact both drug users and non-drug users in the community. The present work reviews the assumptions of the punitive prohibitionist model and its outcomes that present themselves as public health challenges in Puerto Rico. It also presents those principles that should sustain pragmatic drug policy to address problematic drug use from a health and social perspective.

Loneliness as the cause and the effect of problematic Internet use: the relationship between Internet use and psychological well-being.

PubMed

Kim, Junghyun; LaRose, Robert; Peng, Wei

2009-08-01

The current research started from the assumption that one of the major motives driving individuals' Internet use is to relieve psychosocial problems (e.g., loneliness, depression). This study showed that individuals who were lonely or did not have good social skills could develop strong compulsive Internet use behaviors resulting in negative life outcomes (e.g., harming other significant activities such as work, school, or significant relationships) instead of relieving their original problems. Such augmented negative outcomes were expected to isolate individuals from healthy social activities and lead them into more loneliness. Even though previous research suggests that social use of the Internet (e.g., social networking sites, instant messaging) could be more problematic than entertainment use (e.g., downloading files), the current study showed that the former did not show stronger associations than the latter in the key paths leading to compulsive Internet use.

Given the prevalence of Internet use among youth, there is concern that a subset of Internet-using youth may exhibit problematic or addictive patterns of Internet use. The present study examines the association between problematic Internet use (PIU), demographic variables, and health-related measures among Chinese adolescents. Survey data from 1552 adolescents (male=653, mean age=15.43years) from Jilin Province, China, were collected. According to the Young Diagnostic Questionnaire for Internet Addiction (YDQ), 77.8% (n=1207), 16.8% (n=260), and 5.5% (n=85) showed adaptive, maladaptive, and problematic Internet use, respectively. Multinomial logistic regression analysis revealed that gender and family income per month differed between youth showing problematic and adaptive patterns of Internet use. Well-being, self-esteem, and self-control were related to severity of problematic Internet use, with greater severity typically associated with poorer measures in each domain. The findings that severity of problematic Internet use is associated with specific socio-demographic features and temperamental and well-being measures suggest that specific groups of youth may be particularly vulnerable to developing problematic Internet use. Early prevention/intervention programs targeting at-risk groups may help improve public health. Copyright © 2016 Elsevier Ltd. All rights reserved.

A basic need theory approach to problematic Internet use and the mediating effect of psychological distress

The Internet provides an easily accessible way to meet certain needs. Over-reliance on it leads to problematic use, which studies show can be predicted by psychological distress. Self-determination theory proposes that we all have the basic need for autonomy, competency, and relatedness. This has been shown to explain the motivations behind problematic Internet use. This study hypothesizes that individuals who are psychologically disturbed because their basic needs are not being met are more vulnerable to becoming reliant on the Internet when they seek such needs satisfaction from online activities, and tests a model in which basic needs predict problematic Internet use, fully mediated by psychological distress. Problematic Internet use, psychological distress, and basic needs satisfaction were psychometrically measured in a sample of 229 Hong Kong University students and structural equation modeling was used to test the hypothesized model. All indices showed the model has a good fit. Further, statistical testing supported a mediation effect for psychological distress between needs satisfaction and problematic Internet use. The results extend our understanding of the development and prevention of problematic Internet use based on the framework of self-determination theory. Psychological distress could be used as an early predictor, while preventing and treating problematic Internet use should emphasize the fulfillment of unmet needs. PMID:25642201

Childhood maltreatment is associated with many maladaptive outcomes. This study sought to examine the association between childhood maltreatment and problematic social media use using a cross-sectional sample of young adults aged 17-25 years (n = 1029). Specifically, we studied whether the relationship is mediated through (i) attachment anxiety, (ii) attachment avoidance, or (iii) both attachment dimensions operating in series with depressive symptoms. Results revealed that a history of childhood maltreatment was significantly associated with more problematic social media use. Both anxious and avoidant attachment dimensions independently mediated the relationship between childhood maltreatment and problematic use of social media, but in opposing directions. Avoidant attachment was associated with less problematic social media use, whilst anxious attachment was associated with more problematic social media use. Avoidant attachment and depressive symptoms in series accounted for part of the relationship between childhood maltreatment and problematic social media use. Anxious attachment and depressive symptoms in series fully mediated the relationship between childhood maltreatment and problematic social media use. The results suggest that childhood maltreatment may influence social media use directly, but also indirectly. People experiencing depressive symptoms may overuse social media in an attempt to alleviate their distress. However, causality cannot be established with the current design. Copyright © 2018.

To estimate the association between problematic cell phone use and reasoning ability in adolescent. In a stratified cluster sampling design, problematic cell phone use and reasoning ability were evaluated in 929 college students from three universities for twice in one year's follow-up investigation from June 2014 to May 2015. The cross-sectional analysis showed that the score of problematic cell phone use was significantly associated with the score of reasoning ability( the baseline β =-0. 101, 95% CI-0. 168--0. 034; the follow-up in one year's β =-0. 161, 95% CI-0. 255--0. 067). However, the score of problematic cell phone use on the baseline was not associated with the score of reasoning ability in one year late. Interestingly, after controlling of multiple confounding factors and the score of problematic cell phone use on the baseline, the scores of reasoning ability in one year late decreased 0. 40 points( 95%CI-0. 60--0. 20), by the score of problematic cell phone use in one year lateincreased ten percent compared to that on the baseline. Higher problematic cell phone use is significantly associated with poorer reasoning ability in college students.

With the popularity of mobile phones, problematic mobile phone use is getting increasing attention in recent years. Although self-control was found to be a critical predictor of problematic mobile phone use, no study has ever explored the association between self-control and mobile phone use patterns as well as the possible pathway how self-control affects problematic mobile phone use. Four hundred sixty-eight college students were randomly selected in this study. Data were collected using the Problematic Mobile Phone Use Scale, the Self-Control Scale, and the Mobile Phone Use Pattern Questionnaire. Statistical tests were conducted to identify the potential role of mobile phone use patterns in the association between self-control and problematic mobile phone use. In this sample, female students displayed significant higher mobile phone dependence than males. Self-control was negatively correlated with interpersonal, transaction and entertainment mobile phone use patterns, but positively correlated with information seeking use pattern. Self-control could predict problematic mobile phone use directly and indirectly via interpersonal and transaction patterns. Our research provided additional evidence for the negative association between self-control and problematic mobile phone use. Moreover, interpersonal and transaction use patterns played a mediating role in this link.

Common mental health consequences following the experience of potentially traumatic events include Posttraumatic Stress Disorder (PTSD) and addictive behaviors. Problematic smartphone use is a newer manifestation of addictive behaviors. People with anxiety severity (such as PTSD) may be at risk for problematic smartphone use as a means of coping with their symptoms. Unique to our knowledge, we assessed relations between PTSD symptom clusters and problematic smartphone use. Participants (N = 347), recruited through Amazon’s Mechanical Turk (MTurk), completed measures of PTSD and smartphone addiction. Results of the Wald tests of parameter constraints indicated that problematic smartphone use was more related to PTSD’s negative alterations in cognitions and mood (NACM) than to PTSD’s avoidance factor, Wald χ2(1, N = 347) = 12.51, p = 0.0004; and more to PTSD’s arousal compared to PTSD’s avoidance factor, Wald χ2(1, N = 347) = 14.89, p = 0.0001. Results indicate that problematic smartphone use is most associated with negative affect and arousal among trauma-exposed individuals. Implications include the need to clinically assess problematic smartphone use among trauma-exposed individuals presenting with higher NACM and arousal severity; and targeting NACM and arousal symptoms to mitigate the effects of problematic smartphone use.

Health care access for medically underserved patients managing chronic conditions is challenging. While telemedicine can support patient education and engagement, the "digital divide" may be particularly problematic among the medically underserved. This study evaluated physical access to digital devices, use of e-mail and social media tools, and perceptions of telemedicine among American Indian (AI) patients with diabetes mellitus (DM). Survey data were collected from AI patients with DM during teleophthalmology exams. Eighty-eight percent of patients had access to digital device(s), 70% used e-mail, and 56% used social media. Younger age and greater education were positively associated with e-mail and social media use (p < .05). Most (60%) considered telemedicine an excellent medium for health-related patient education. American Indian patients with DM had access enabling patient education via telemedicine. Future work should examine patient technology preferences and effectiveness of technology-based education in improving outcomes among medically underserved populations.

Laser processing of substrates for light-emitting diodes (LEDs) offers advantages over other processing techniques and is therefore an active research area in both industrial and academic sectors. The processing of sapphire wafers is problematic because sapphire is a hard and brittle material. Semiconductor laser scribing processing suffers certain disadvantages that have yet to be overcome, thereby necessitating further investigation. In this work, a platform for controllable laser thermal cleavage was constructed. A sapphire LED wafer was modeled using the finite element method to simulate the thermal and stress distributions under different conditions. A guide groove cut by laser ablation before the cleavage process was observed to guide the crack extension and avoid deviation. The surface and cross section of sapphire wafers processed using controllable laser thermal cleavage were characterized by scanning electron microscopy and optical microscopy, and their morphology was compared to that of wafers processed using stealth dicing. The differences in luminous efficiency between substrates prepared using these two processing methods are explained.

Novel Rubidium Poly-Nitrogen Energetic Materials

Huff, Ashley; Steele, Brad; Oleynik, Ivan

High-nitrogen content compounds are being actively explored with the goal of discovering new high-energy density materials with performance surpassing the conventional energetic materials such as HMX or RDX. Although pure polynitrogen compounds such as cg-N are predicted to deliver 10-fold increase in detonation pressure and detonation velocity of 30 km/s, their synthesis and recovery at ambient conditions is problematic. Doping polynitrogens with other elements is a viable route to promote metastability while reducing synthesis pressure. In this work, rubidium poly-nitrides are being investigated as candidates for high energy density materials. Using first principles evolutionary structure search methods performed at varying stoichiometries and several pressures ranging from 0 to 100 GPa, several new polynitrogen compounds have been discovered. The phase diagrams containing thermodynamically stable and lowest metastable phases are calculated and the dynamical stability of the promising materials is investigated at various pressures. Raman spectra and XRD patterns are also calculated to provide experimentally relevant information useful for identification of these compounds during their synthesis.

Mobile phone use is banned or regulated in some circumstances. Despite recognized safety concerns and legal regulations, some people do not refrain from using mobile phones. Such problematic mobile phone use can be considered to be an addiction-like behavior. To find the potential predictors, we examined the correlation between problematic mobile phone use and personality traits reported in addiction literature, which indicated that problematic mobile phone use was a function of gender, self-monitoring, and approval motivation but not of loneliness. These findings suggest that the measurements of these addictive personality traits would be helpful in the screening and intervention of potential problematic users of mobile phones.

Designing Science Learning Environments That Support Emerging Bilingual Students to Problematize Electrical Phenomena

NASA Astrophysics Data System (ADS)

Suarez, Enrique A.

This dissertation investigates how emerging bilingual students make sense of natural phenomena through engaging in certain epistemic practices of science, and the elements of the learning environment that created those opportunities. Specifically, the dissertation focuses on how emerging bilingual students problematized electrical phenomena, like electric flow and electrical resistance, and how the design features of the environment (e.g., sequencing of activities, linguistic practices) may have supported students as they made sense of phenomena. The first study describes how for students presented and evaluated mechanistic models of electric flow, focusing specifically on how students identified and negotiated a disagreement between their explanatory models. The results from this study highlight the complexity of students' disagreements, not only because of the epistemological aspects related to presenting and evaluating knowledge, but also due to interpersonal dynamics and the discomfort associated with disagreeing with another person. The second study focuses on the design features of the learning environment that supported emerging bilingual students' investigations of electrical phenomena. The findings from this study highlight how a carefully designed set of activities, with the appropriate material resources (e.g., experimental tools), could support students to problematize electrical resistance. The third study describes how emerging bilingual students engaged in translanguaging practices and the contextual features of the learning environment that created and hindered opportunities for translanguaging. The findings from this study identify and articulate how emerging bilingual students engaged in translanguaging practices when problematizing electrical resistance, and strengthen the perspective that, in order to be equitable for emerging bilingual students, science learning environments need to act as translanguaging spaces. This dissertation makes three contributions to how science educators understand how elementary-aged emerging bilingual students learning science. First, I offer a detailed account of how emerging bilingual students engaged in epistemic practices to problematize electrical phenomena. Secondly, I argue learning environments need to create opportunities for emerging bilingual students to engage in productive epistemic work through leveraging multiple kinds of resources from their semiotic repertoires. Finally, this dissertation contributes to our understanding of how emerging bilingual students engage in translanguaging practices as they investigate and talk about the natural world.

The aim of the study was to relate the basic dimensions of personality formulated by the model of the big five factors with problematic Internet use in a sample of 411 Colombian youngsters, 18-28 years of age, attending three private universities. Online survey questionnaires were administered for: socio-demographics and Internet usage habits, the Big Five Inventory (John, Donahue and Kentle, 1991), to assess personality, and the Internet Addiction Test (Young, 1998), to determine the degree of use of the Internet (controlled, problematic or addictive). The results revealed that 9.7% of the sample has a problematic Internet use. Among them, the majority were male (x2= 12.93, p= 0.01) and performing communication and leisure activities. The problematic use correlates positively with neuroticism and negatively with friendliness and responsibility. On the other hand, is not related to extraversion and openness to experience. Being female and the responsibility dimension are protective factors from problematic use, while neuroticism predicts it. In conclusion, the study data provides empirical evidence of the relationship between personality and problematic Internet use.

Primary care physicians (General Practitioners (GPs)) play a pivotal role in providing end of life care (EoLC). However, many lack confidence in this area, and the quality of EoLC by GPs can be problematic. Evidence regarding educational needs, learning preferences and the acceptability of evaluation methods is needed to inform the development and testing of EoLC education. This study therefore aimed to explore GPs' EoLC educational needs and preferences for learning and evaluation. A qualitative focus group study was conducted with qualified GPs and GP trainees in the UK. Audio recordings were transcribed and analysed thematically. Expert review of the coding frame and dual coding of transcripts maximised rigour. Twenty-eight GPs (10 fully qualified, 18 trainees) participated in five focus groups. Four major themes emerged: (1) why education is needed, (2) perceived educational needs, (3) learning preferences, and (4) evaluation preferences. EoLC was perceived as emotionally and clinically challenging. Educational needs included: identifying patients for palliative care; responsibilities and teamwork; out-of-hours care; having difficult conversations; symptom management; non-malignant conditions; and paediatric palliative care. Participants preferred learning through experience, working alongside specialist palliative care staff, and discussion of real cases, to didactic methods and e-learning. 360° appraisals and behavioural assessment using videoing or simulated interactions were considered problematic. Self-assessment questionnaires and patient and family outcome measures were acceptable, if used and interpreted correctly. GPs require education and support in EoLC, particularly the management of complex clinical care and counselling. GPs value mentoring, peer-support, and experiential learning alongside EoLC specialists over formal training.

The farrier's work environment.

Löfqvist, Lotta; Pinzke, Stefan

The horse industry in Sweden has rapidly expanded in recent years. This increasing number of horses implies a greater need for more farriers. Shoeing a horse is hard physical work, and includes awkward work postures and repetitive movements. It is well known that hard physical work increases the risk of injuries and musculoskeletal problems. The risk is especially high for musculoskeletal disorders when certain movements are constantly repeated. Heavy or repeated unilateral loads lead to considerable stress on the muscles, which can lead to rupture and fatigue that can cause long term problems. A case study showed that farriers worked 75% of their work time with their backs in bent positions (often more than 70 degrees). Farriers are also exposed to risk factors in their physical environment like dust, noise and poor lighting. Risk of kicks and bites, eye injuries and burns are other factors that make their work environment hazardous. There are only a few studies available that have documented the farriers' working environment and these are not of recent date. A US study from 1984 described kicks and bites from horses, metal splinters in the eyes, heat exhaustion and problematic postures to be perceived as the greatest risks in their work. The back, knees and wrists were the most exposed body regions. There is a need for more current and in-depth studies investigating the farriers' working conditions in order to gain more knowledge of their health and work environment. The aim of the present study is to investigate the physical health and work environment of farriers. The investigation will use questionnaires, work load measurements and workplace analysis. The results will serve as a base for improvements concerning the design of the workplace, equipment, tools and aids as well as supplying recommendations about physical exercise and the correct work technique, etc. The results are planned to be incorporated in the education of farriers.

We examined cognitive deficits in problematic drinkers with and without mild to borderline intellectual disability (MBID). Problematic drinkers were expected to show a significantly lower estimated performance IQ (PIQ), but not a lower estimated verbal IQ (VIQ), compared to light drinkers. Participants ( N = 474) were divided into four groups based on IQ and severity of alcohol use-related problems. IQ was estimated using (a short form of) the Wechsler Adult Intelligence Scale third edition. Severity of alcohol use-related problems was assessed using the Alcohol Use Disorder Identification Test. Overall, there were no significant differences between light and problematic drinkers on estimated VIQ. Within the group without MBID, estimated PIQ was significantly lower. Estimated PIQ was not lower in problematic drinkers with MBID compared to light drinkers with MBID. The results are indicative of cognitive deficits in problematic drinkers without MBID. Screening for cognitive deficits with additional instruments is advised.

Background. Context is important in implementation—we know that what works in one setting may not work in the same way elsewhere. Primary care has been described as a unique context both in relation to the care delivered and efforts to carry out research and implementation of new evidence. Objective. To explore some of the distinctive features of the primary care environment that may influence implementation. Methods. We conducted an ethnographic study involving observations, interviews and documentary analysis of the ENABLE-CKD project, which involved general practices implementing a chronic kidney disease care bundle and offering self-management support tools to patients. Analysis was based on the constant comparative method. Results. Four elements of the primary care environment emerged as important influences on the extent to which implementation was successful. First, the nature of delivering care in this setting meant that prioritizing one condition over others was problematic. Second, the lack of alignment with financial and other incentives affected engagement. Third, the project team lacked mechanisms through which engagement could be mandated. Fourth, working relationships within practices impacted on engagement. Conclusions. Those seeking to implement interventions in primary care need to consider the particular context if they are to secure successful implementation. We suggest that there are particular kinds of interventions, which may be best suited to the primary care context. PMID:27297465

Problematic drinking and executive functioning deficits are two known risk factors for intimate partner aggression (IPA). However, executive functioning is a multifaceted construct, and it is not clear whether deficits in specific components of executive functioning are differentially associated with IPA perpetration generally and within the context of problematic alcohol use. To address this question, the present study investigated the effects of problematic drinking and components of executive functioning on physical IPA perpetration within a dyadic framework. Participants were 582 heavy drinking couples (total n = 1164) with a recent history of psychological and/or physical IPA recruited from two metropolitan cities in the USA. Multilevel models were used to examine effects within an actor-partner interdependence framework. The highest levels of physical IPA were observed among actors who reported everyday consequences of executive functioning deficits related to emotional dysregulation whose partners were problematic drinkers. However, the association between executive functioning deficits related to emotional dysregulation and IPA was stronger towards partners who were non-problematic drinkers relative to partners who were problematic drinkers. No such effect was found for executive functioning deficits related to behavioural regulation. Results provide insight into how problematic drinking and specific executive functioning deficits interact dyadically in relation to physical IPA perpetration.

Intense video gaming is not essentially problematic.

Video games are more popular than ever and the general public, including parents, educators, and the media, tends to consider intense video gaming fundamentally problematic. To test this hypothesis, participants were recruited via gaming-related websites resulting in a sample of N = 5,222 online video gamers (mean age: 22.2 years, SD = 6.4). Besides assessing gaming time, we administered the Ten-Item Internet Gaming Disorder Test, the Brief Symptom Inventory, and the Motives for Online Gaming Questionnaire. Two structural regression models were estimated with both gaming time and problematic gaming as outcome variables. Predictors were psychiatric symptoms in the first, and gaming motives in the second model. Both models yielded adequate fit indices. Psychiatric symptoms had a moderate positive effect on problematic use (β = .46, p < .001) whereas their effect on gaming time was practically zero (β = -.01, p = .84). In the second model, Escape was the most prominent motive and was moderately to-strongly associated (β = .58, p < .001) with problematic use. However, the association between Escape and gaming time was substantially weaker (β = .21, p < .001). The correlation between gaming time and problematic use was weak-to-moderate in both models (r = .26, p < .001 and r = .21, p < .001, respectively). Data suggest that gaming time is weakly associated with negative psychological factors such as psychiatric symptoms and Escape motive, which were found to be consistently related to problematic use. Therefore, the amount of gaming time alone appears to be an unreliable predictor of problematic use, which questions the aforementioned idea that intense gaming is essentially problematic.

To review the clinical features and complications of at-risk cannabis use and cannabis use disorder, and to outline an office-based protocol for screening, identifying, and managing this disorder. PubMed was searched for controlled trials, observational studies, and reviews on cannabis use among adolescents and young adults; cannabis-related medical and psychiatric harms; cannabis use disorder and its treatment; and lower-risk cannabis use guidelines. Physicians should ask all patients about cannabis use. They should ask adolescents and young adults and those at highest risk of cannabis-related harms (those with concurrent psychiatric or substance use disorders) more frequently. Physicians should also ask about cannabis use in patients who have problems that could be caused by cannabis, such as mood disorders, psychosis, and respiratory symptoms. In patients who report cannabis use, physicians should inquire about frequency and amount, tolerance and withdrawal symptoms, attempts to reduce use, and cannabis-related harms. Lower-risk cannabis users smoke, inhale, or ingest cannabis occasionally without evidence of school, work, or social dysfunction; those with problematic use often use cannabis daily or almost daily, have difficulty reducing their use, and have impaired school, work, or social functioning. Physicians should offer all patients with problematic use brief advice and counseling, focusing on the health effects of cannabis and setting a goal of abstinence (some higher-risk groups should not use cannabis at all) or reduced use, and they should provide practical strategies to reduce cannabis use. Physicians should incorporate simple motivational interviewing techniques into the counseling sessions. They should refer those patients who are unable to reduce use or who are experiencing harms from cannabis use to specialized care, while ensuring those patients remain connected to primary care. As well, physicians should give information on lower-risk cannabis use to all cannabis users. Physicians should screen all patients in their practices at least once for cannabis use, especially those who have problems that might be caused by cannabis. Physicians should screen those at higher risk more often, at least annually. Lower-risk cannabis use should be distinguished from problematic use. Brief counseling should be provided to those with problematic use; these patients should be referred to specialists if they are unable to reduce or cease use.

The current meta-analysis is the first to examine the associations between problematic Facebook use, psychological distress (i.e., depression, anxiety, etc.) and well-being (life satisfaction, positive mental health) among adolescents and young adults. A comprehensive search strategy identified relevant studies in PsychInfo, Pubmed, Scopus, ResearchGate, and Google Scholar. The final sample included 23 independent samples with a total of 13,929 participants (60.7% females; M age = 21.93, range: 16.5-32.4). Results of random effects meta-analysis confirmed a positive correlation between problematic Facebook use and psychological distress (r = .34, 95% CI [.28, .39]). Moderation analysis revealed that effect sizes were larger in older samples. Moreover, a negative correlation between problematic Facebook use and well-being was observed (r = -.22, 95% CI [-.28, -.15]). All available studies used a cross-sectional design thus hampering the possibility to establish the direction of the association between problematic Facebook use and psychological distress and well-being. Results are discussed within the extant literature on problematic Facebook use and future research directions are proposed. This research may also inform clinical and prevention interventions on problematic Facebook use. Copyright © 2017 Elsevier B.V. All rights reserved.

Introduction and Aims Problematic drinking and executive functioning deficits are two known risk factors for intimate partner aggression (IPA). However, executive functioning is a multifaceted construct, and it is not clear whether deficits in specific components of executive functioning are differentially associated with IPA perpetration generally and within the context of problematic alcohol use. To address this question, the present study investigated the effects of problematic drinking and components of executive functioning on physical IPA perpetration within a dyadic framework. Design and Methods Participants were 582 heavy drinking couples (total N = 1,164) with a recent history of psychological and/or physical IPA recruited from two metropolitan cities in the United States. Multilevel models were used to examine effects within an Actor-Partner Interdependence framework. Results The highest levels of physical IPA were observed among Actors who reported everyday consequences of executive functioning deficits related to emotional dysregulation whose partners were problematic drinkers. However, the association between executive functioning deficits related to emotional dysregulation and IPA was stronger toward partners who were non-problematic drinkers relative to partners who were problematic drinkers drinkers. No such effect was found for executive functioning deficits related to behavioral regulation. Discussion and Conclusions Results provide insight into how problematic drinking and specific executive functioning deficits interact dyadically in relation to physical IPA perpetration.

Interrelations Between Adolescent Problematic Internet Use and Parental Internet Mediation Everyday life of adolescents and their parents is increasingly characterized by digital media usage (also referred to as "process of mediatization"). In the current study, associations between problematic Internet use of the adolescents (as a possible consequence of the process of mediatization) and parental media education were explored. For this purpose, throughout Germany 1,095 family dyads (an adolescent and a related parent) were investigated with a standardized questionnaire measuring different aspects of parental media education and adolescent problematic Internet use. We conducted two multiple linear regression analyses (dimensional approach) with adolescent problematic Internet use based on self-ratings (model 1, corrected R 2 = 0.18) and parental assessment (model 2, corrected R 2 = 0.24) as response variables. Consistently for self- and parental ratings, adolescent problematic Internet use was statistically significant related to male gender (of the adolescent), a more frequent inconsistent media education (adolescents' and parents' perspective) and a stronger monitoring (parents' perspective). Additionally, we observed associations between the parental rating of adolescent problematic Internet use and a less frequent active and restrictive Internet Mediation (parents' perspective). The findings of the present study show the importance of parental media education for problematic Internet use in adolescence and especially, the role of inconsistent media education should be investigated again in further studies.

Internet addiction or problematic Internet use is a recent and increasingly recognized disorder which has been consistently associated with many psychiatric disorders, adding to the documented negative consequences of problematic Internet use. However, very few studies have examined the relationship between problematic Internet use and personality traits and none in a French sample. Moreover, those which have evaluated this relationship have mainly been conducted on small samples. The main goal of our study was to explore the relationship between problematic Internet use, time spent online and personality traits in a French sample, taking into account the presence of depressive symptoms, and gender. A sample of 276 participants aged from 18 to 50 (M=28; SD=8.9) completed a questionnaire assessing problematic Internet use, time spent online, the presence of ten personality traits and depressive symptoms. Our results revealed significant differences between genders. Among men, problematic Internet use was associated with personality clusters A and B while in women no cluster or personality traits were associated. Time spent online was predicted by schizoid personality traits among men and avoidant personality traits among women. Our results indicate that cluster A (schizoid and schizotypal) and cluster B traits (borderline and antisocial) play a more important role in problematic Internet use than cluster C traits among men. Differences between men and women regarding the relationships between personality traits, time online and problematic Internet use may be related to differences in the activities engaged in by men and women online. We observed that communication websites use was more prevalent among women while erotic, gambling and shopping websites use was more prevalent among men suggesting that the characteristics of problematic Internet use may vary according to gender. Few studies have examined the relationship between problematic Internet use, time spent online and personality traits, and none among a French sample. These results suggest the importance of assessing the impact of personality traits on Internet use, particularly on time spent online, by differentiating results in terms of gender and online activities.

Graph Theory-Based Technique for Isolating Corrupted Boundary Conditions in Continental-Scale River Network Hydrodynamic Simulation

Yu, C. W.; Hodges, B. R.; Liu, F.

2017-12-01

Development of continental-scale river network models creates challenges where the massive amount of boundary condition data encounters the sensitivity of a dynamic nu- merical model. The topographic data sets used to define the river channel characteristics may include either corrupt data or complex configurations that cause instabilities in a numerical solution of the Saint-Venant equations. For local-scale river models (e.g. HEC- RAS), modelers typically rely on past experience to make ad hoc boundary condition adjustments that ensure a stable solution - the proof of the adjustment is merely the sta- bility of the solution. To date, there do not exist any formal methodologies or automated procedures for a priori detecting/fixing boundary conditions that cause instabilities in a dynamic model. Formal methodologies for data screening and adjustment are a critical need for simulations with a large number of river reaches that draw their boundary con- dition data from a wide variety of sources. At the continental scale, we simply cannot assume that we will have access to river-channel cross-section data that has been ade- quately analyzed and processed. Herein, we argue that problematic boundary condition data for unsteady dynamic modeling can be identified through numerical modeling with the steady-state Saint-Venant equations. The fragility of numerical stability increases with the complexity of branching in river network system and instabilities (even in an unsteady solution) are typically triggered by the nonlinear advection term in Saint-Venant equations. It follows that the behavior of the simpler steady-state equations (which retain the nonlin- ear term) can be used to screen the boundary condition data for problematic regions. In this research, we propose a graph-theory based method to isolate the location of corrupted boundary condition data in a continental-scale river network and demonstrate its utility with a network of O(10^4) elements.

Background Little research has investigated the correlates of problematic tanning and tanning dependence. Objective To identify characteristics associated with problematic tanning and tanning dependence, and to evaluate simultaneously the associations of variables as correlates of problematic tanning and tanning dependence. Method To assess tanning-related characteristics, psychopathology, and demographics, we administered questionnaires to 533 tanning university students; 31% met criteria for tanning dependence, 12% for problematic tanning. Results Both problematic tanning and tanning dependence were significantly associated with being female (p < .001; p < .001, respectively) and with higher scores on screening measures of obsessive-compulsive (p < .001, p = .005, respectively) and body dysmorphic disorders (p = .019, p < .001, respectively). Frequency of tanning in the past month was the strongest correlate of problematic tanning (p < .001) and tanning dependence (p < .001) when included in a model that controlled for shared variance among demographics and psychopathology. Limitations The sample was recruited from one university and contained only self-report measures. Conclusion Results suggest that those who engage in excessive tanning may also have significant psychiatric distress. Additional research is needed to characterize compulsive, problematic tanning as well as its rates, correlates, and risk factors among diverse samples. PMID:24373775

Neuroimaging findings suggest that excessive Internet use shows functional and structural brain changes similar to substance addiction. Even though it is still under debate whether there are gender differences in case of problematic use, previous studies by-passed this question by focusing on males only or by using gender matched approach without controlling for potential gender effects. We designed our study to find out whether there are structural correlates in the brain reward system of problematic Internet use in habitual Internet user females. T1-weighted Magnetic Resonance (MR) images were collected in 82 healthy habitual Internet user females. Structural brain measures were investigated using both automated MR volumetry and voxel based morphometry (VBM). Self-reported measures of problematic Internet use and hours spent online were also assessed. According to MR volumetry, problematic Internet use was associated with increased grey matter volume of bilateral putamen and right nucleus accumbens while decreased grey matter volume of orbitofrontal cortex (OFC). Similarly, VBM analysis revealed a significant negative association between the absolute amount of grey matter OFC and problematic Internet use. Our findings suggest structural brain alterations in the reward system usually related to addictions are present in problematic Internet use.

Background and aims Gaming applications have become one of the main entertainment features on smartphones, and this could be potentially problematic in terms of dangerous, prohibited, and dependent use among a minority of individuals. A cross-national study was conducted in Belgium and Finland. The aim was to examine the relationship between gaming on smartphones and self-perceived problematic smartphone use via an online survey to ascertain potential predictors. Methods The Short Version of the Problematic Mobile Phone Use Questionnaire (PMPUQ-SV) was administered to a sample comprising 899 participants (30% male; age range: 18-67 years). Results Good validity and adequate reliability were confirmed regarding the PMPUQ-SV, especially the dependence subscale, but low prevalence rates were reported in both countries using the scale. Regression analysis showed that downloading, using Facebook, and being stressed contributed to problematic smartphone use. Anxiety emerged as predictor for dependence. Mobile games were used by one-third of the respective populations, but their use did not predict problematic smartphone use. Very few cross-cultural differences were found in relation to gaming through smartphones. Conclusion Findings suggest mobile gaming does not appear to be problematic in Belgium and Finland.

The Internet is an essential part of everyday life, particularly for the younger generation. The aims of this study were to evaluate nursing students' problematic Internet use and time management skills and to assess relationship between Internet use and time management. This descriptive study was conducted with 311 nursing students in Ankara, Turkey, from February to April 2016. The data were collected using the Problematic Internet Use Scale and Time Management Inventory. The Problematic Internet Use Scale and Time Management Inventory median scores were 59.58 ± 20.69 and 89.18 ± 11.28, respectively. There were statistically significant differences between both nursing students' Problematic Internet Use Scale and Time Management Inventory median scores and some variables (school grade, the time spent on the Internet). Fourth-year students were more prone to excessive use of the Internet and the resulting negative consequences than students from other year levels (P < .05). A significant negative relationship was also found between problematic Internet use and time management (P < .05). This study demonstrates that the Internet use of participants was not problematic and their time management skills were on a moderate level.

The Role of Aircraft Motion in Airborne Gravity Data Quality

Many factors contribute to the quality of airborne gravity data measured with LaCoste and Romberg-type sensors, such as the Micro-g LaCoste Turnkey Airborne Gravity System used by the National Geodetic Survey's GRAV-D (Gravity for the Redefinition of the American Vertical Datum) Project. For example, it is well documented that turbulence is a big factor in the overall noise level of the measurement. Turbulence is best controlled by avoidance; thus flights in the GRAV-D Project are only undertaken when the predicted wind speeds at flight level are ≤ 40 kts. Tail winds are known to be particularly problematic. The GRAV-D survey operates on a number of aircraft in a variety of wind conditions and geographic locations, and an obvious conclusion from our work to date is that the aircraft itself plays an enormous role in the quality of the airborne gravity measurement. We have identified a number of features of the various aircraft which can be determined to play a role: the autopilot, the size and speed of the aircraft, inherent motion characteristics of the airframe, tip tanks and other modifications to the airframe to reduce motion, to name the most important. This study evaluates the motion of a number of the GRAV-D aircraft and looks at the correlation between this motion and the noise characteristics of the gravity data. The GRAV-D Project spans 7 years and 42 surveys, so we have a significant body of data for this evaluation. Throughout the project, the sensor suite has included an inertial measurement unit (IMU), first the Applanix POSAv, and then later the Honeywell MicroIRS IMU as a part of a NovAtel SPAN GPS/IMU system. We compare the noise characteristics of the data with measures of aircraft motion (via pitch, roll, and yaw captured by the IMU) using a variety of statistical tools. It is expected that this comparison will support the conclusion that certain aircraft tend to work well with this type of gravity sensor while others tend to be problematic in general.

We get the algorithms of our ground truths: Designing referential databases in digital image processing

PubMed Central

Jaton, Florian

2017-01-01

This article documents the practical efforts of a group of scientists designing an image-processing algorithm for saliency detection. By following the actors of this computer science project, the article shows that the problems often considered to be the starting points of computational models are in fact provisional results of time-consuming, collective and highly material processes that engage habits, desires, skills and values. In the project being studied, problematization processes lead to the constitution of referential databases called ‘ground truths’ that enable both the effective shaping of algorithms and the evaluation of their performances. Working as important common touchstones for research communities in image processing, the ground truths are inherited from prior problematization processes and may be imparted to subsequent ones. The ethnographic results of this study suggest two complementary analytical perspectives on algorithms: (1) an ‘axiomatic’ perspective that understands algorithms as sets of instructions designed to solve given problems computationally in the best possible way, and (2) a ‘problem-oriented’ perspective that understands algorithms as sets of instructions designed to computationally retrieve outputs designed and designated during specific problematization processes. If the axiomatic perspective on algorithms puts the emphasis on the numerical transformations of inputs into outputs, the problem-oriented perspective puts the emphasis on the definition of both inputs and outputs.

Interactive segmentation of tongue contours in ultrasound video sequences using quality maps

2014-03-01

Ultrasound (US) imaging is an effective and non invasive way of studying the tongue motions involved in normal and pathological speech, and the results of US studies are of interest for the development of new strategies in speech therapy. State-of-the-art tongue shape analysis techniques based on US images depend on semi-automated tongue segmentation and tracking techniques. Recent work has mostly focused on improving the accuracy of the tracking techniques themselves. However, occasional errors remain inevitable, regardless of the technique used, and the tongue tracking process must thus be supervised by a speech scientist who will correct these errors manually or semi-automatically. This paper proposes an interactive framework to facilitate this process. In this framework, the user is guided towards potentially problematic portions of the US image sequence by a segmentation quality map that is based on the normalized energy of an active contour model and automatically produced during tracking. When a problematic segmentation is identified, corrections to the segmented contour can be made on one image and propagated both forward and backward in the problematic subsequence, thereby improving the user experience. The interactive tools were tested in combination with two different tracking algorithms. Preliminary results illustrate the potential of the proposed framework, suggesting that the proposed framework generally improves user interaction time, with little change in segmentation repeatability.

Family physicians' experiences when collaborating with district nurses in home care-based medical treatment. A grounded theory study.

This article concerns Swedish family physicians' (FPs) experiences collaborating with district nurses (DNs) when the DNs provide medical treatment for home care patients. The aim was to develop a model to illuminate this process from the FPs' perspective. Semi-structured interviews were conducted with 13 FPs concerning one of their patients with home care by a DN. The interview focused on one patient's treatment and care by different care providers and the collaboration among them. Grounded theory methodology (GTM) was used in the analyses. It was essential for FPs to collaborate with and rely on DNs in the medical treatment of home care patients. According to the FPs, factors such as the disease, FPs' working conditions and attitude determined how much of the initiative in this treatment FPs retained or left to DNs. Depending on the circumstances, two different roles were adopted by the individual FPs: medical conductors who retain the initiative and medical consultants who leave the initiative to DNs. Factors as the disease, DNs' attitudes towards collaboration and DNs' working conditions influenced whether or not the FPs felt that grounds for relying on DNs were satisfactory. Regardless of the role of the FP, conditions for medical treatment were judged by the FPs to be good enough when the grounds for relying on the DN were satisfactory and problematic when they were not. In the role of conductor, the FP will identify when the grounds for relying on the DN are unsatisfactory and be able to take action, but in the role of consultant the FP will not detect this, leaving home care patients without appropriate support. Only when there are satisfactory grounds for relying on the DN, will conditions for providing home care medical treatment be good enough when the FP adopts a consultative role.

Empirical studies have identified increasing rates of problematic Internet use worldwide and a host of related negative consequences. However, researchers disagree as to whether problematic Internet use is a subtype of behavioral addiction. Thus, there are not yet widely accepted and validated diagnostic criteria for problematic Internet use. To address this gap, we used mixed-methods to examine the extent to which signs and symptoms of problematic Internet use mirror DSM-5 diagnostic criteria for substance use disorder, gambling disorder, and Internet gaming disorder. A total of 27 university students, who self-identified as intensive Internet users and who reported Internet-use-associated health and/or psychosocial problems were recruited. Students completed two measures that assess problematic Internet use (Young's Diagnostic Questionnaire and the Compulsive Internet Use Scale) and participated in focus groups exploring their experiences with problematic Internet use. Results of standardized measures and focus group discussions indicated substantial overlap between students' experiences of problematic Internet use and the signs and symptoms reflected in the DSM-5 criteria for substance use disorder, gambling disorder, and Internet gaming disorder. These signs and symptoms included: a) use Internet longer than intended, b) preoccupation with the Internet, c) withdrawal symptoms when unable to access the Internet, d) unsuccessful attempts to stop or reduce Internet use, e) craving, f) loss of interest in hobbies or activities other than the Internet, g) excessive Internet use despite the knowledge of related problems, g) use of the Internet to escape or relieve a negative mood, and h) lying about Internet use. Tolerance, withdrawal symptoms, and recurrent Internet use in hazardous situations were uniquely manifested in the context of problematic Internet use. Implications for research and practice are discussed.

2014-04-01

Although a mobile phone is useful and attractive as a tool for communication and interpersonal interaction, there exists the risk of its problematic or addictive use. This study aims to investigate the correlation between the big-five personality domains and problematic mobile phone use. The Mobile Phone Problem Usage Scale and the NEO Five-Factor Inventory (NEO-FFI) were employed in this study. Survey data were gathered from 504 university students for multiple regression analysis. Problematic mobile phone use is a function of gender, extraversion, neuroticism, openness-to-experience; however, it is not a function of agreeableness or conscientiousness. The measurement of these predictors would enable the screening of and intervening in the potentially problematic behaviors of mobile phone users.

Problematic eating behaviors in adolescents with low self-esteem and elevated depressive symptoms.

Previous research has indicated that low self-esteem may be an important risk factor for the development of eating disorders. Few longitudinal studies have examined the relationships between low self-esteem, depressive symptoms, and eating disorders in adolescents. The present study investigated whether low self-esteem was associated with depressive symptoms and problematic eating behaviors. Measures of low self-esteem and problematic eating behaviors were administered to a sample of 197 adolescent primary-care patients. Depressive symptoms and problematic eating behaviors were assessed ten months later. Youths with low self-esteem were at greater risk for high levels of depressive symptoms and eating disorder symptoms. In addition, depressive symptoms mediated the association of low self-esteem with problematic eating behaviors.

Problematic topic transitions in dysarthric conversation.

Bloch, Steven; Saldert, Charlotta; Ferm, Ulrika

2015-01-01

This study examined the nature of topic transition problems associated with acquired progressive dysarthric speech in the everyday conversation of people with motor neurone disease. Using conversation analytic methods, a video collection of five naturally occurring problematic topic transitions was identified, transcribed and analysed. These were extracted from a main collection of over 200 other-initiated repair sequences and a sub-set of 15 problematic topic transition sequences. The sequences were analysed with reference to how the participants both identified and resolved the problems. Analysis revealed that topic transition by people with dysarthria can prove problematic. Conversation partners may find transitions problematic not only because of speech intelligibility but also because of a sequential disjuncture between the dysarthric speech turn and whatever topic has come prior. In addition the treatment of problematic topic transition as a complaint reveals the potential vulnerability of people with dysarthria to judgements of competence. These findings have implications for how dysarthria is conceptualized and how specific actions in conversation, such as topic transition, might be suitable targets for clinical intervention.

Prior studies have suggested that affect lability might reduce the risk for problematic drinking among sensation seekers by compensating for their deficiencies in emotional reactivity and among individuals high on negative urgency by disrupting stable negative emotions. Due to the high prevalence of college drinking, this study examined whether affect lability interacted with sensation seeking and negative urgency to influence college student problematic drinking. 414 college drinkers (mean age: 20, 77% female, and 74% Caucasian) from a US Midwestern University completed self-administered questionnaires online. Consistent with our hypotheses, our results indicated that the effects of sensation seeking and negative urgency on problematic drinking weakened at higher levels of affect lability. These findings emphasize the importance of considering specific emotional contexts in understanding how negative urgency and sensation seeking create risk for problematic drinking among college students. These findings might also help us better understand how to reduce problematic drinking among sensation seekers and individuals high on negative urgency.

Novelty-seeking tendencies in adolescents may promote innovation as well as problematic impulsive behaviour, including drug abuse. Previous research has not clarified whether neural hyper- or hypo-responsiveness to anticipated rewards promotes vulnerability in these individuals. Here we use a longitudinal design to track 144 novelty-seeking adolescents at age 14 and 16 to determine whether neural activity in response to anticipated rewards predicts problematic drug use. We find that diminished BOLD activity in mesolimbic (ventral striatal and midbrain) and prefrontal cortical (dorsolateral prefrontal cortex) regions during reward anticipation at age 14 predicts problematic drug use at age 16. Lower psychometric conscientiousness and steeper discounting of future rewards at age 14 also predicts problematic drug use at age 16, but the neural responses independently predict more variance than psychometric measures. Together, these findings suggest that diminished neural responses to anticipated rewards in novelty-seeking adolescents may increase vulnerability to future problematic drug use. PMID:28221370

The aim of this study was to identify problematic gaming behavior among Finnish adolescents and young adults, and evaluate its connection to a variety of psychological, social, and physical health symptoms. This cross-sectional study was conducted with a random sample of 293 respondents aged from 13 to 24 years. Participants completed an online survey. Problematic gaming behavior was measured with the Game Addiction Scale (GAS). Self-reports covered health measures such as psychological health (psychopathological symptoms, satisfaction with life), social health (preferences for social interaction), and physical health (general health, Body Mass Index [BMI], body discomfort, physical activity). Problematic gaming behavior was found to relate to psychological and health problems, namely fatigue, sleep interference, depression and anxiety symptoms. Multiple linear regression indicated that the amount of weekly gaming, depression and a preference for online social interaction predicted increased problematic gaming symptoms. This research emphasized that problematic gaming behavior had a strong negative correlation to a variety of subjective health outcomes.

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

Background and aims Tinder is a geo-located online dating application, which is present in almost 200 countries and has 10 million daily users. The aim of the present research was to investigate the motivational, personality, and basic psychological need-related background of problematic Tinder use. Methods After qualitative pretest and item construction, in Study 1 (N = 414), confirmatory factor analysis was conducted to corroborate the different motivational factors behind Tinder use. In Study 2 (N = 346), the associations between Big Five traits, Tinder motivations, and problematic Tinder use were examined with structural equation modeling (SEM). In Study 3 (N = 298), the potential role of general self-esteem, relatedness need satisfaction, and frustration in relation to Tinder-use motivations and problematic Tinder use was examined with SEM. Results In Study 1, a 16-item first-order factor structure was identified with four motivational factors, such as sex, love, self-esteem enhancement, and boredom. In Study 2, problematic Tinder use was mainly related to using Tinder for self-esteem enhancement. The Big Five personality factors were only weakly related to the four motivations and to problematic Tinder use. Counterintuitively, Study 3 showed that instead of global self-esteem, relatedness need frustration was the strongest predictor of self-esteem enhancement Tinder-use motivation which, in turn, was the strongest predictor of problematic Tinder use. Discussion Four motivational factors were identified as predictors of problematic use with need frustration being a relevant background variable instead of general personality traits.

Problematic internet use may lead to serious psychosocial dysfunction. Recent studies have found comparable prevalence in both male and female adolescents. We pursue the neglected questions how male and female adolescents differ regarding their patterns of internet use and how gender, peer attachment and patterns of use are related to pathological internet use. In 2410 adolescents (1307 girls and 1103 boys) aged 12-18 years from different types of school we assessed peer attachment, frequency and use of eight specific applications and indicators of pathological internet use. Three patterns of internet use, 'social'; 'sex and games" and 'functional' were identified and connections between variables were modeled by ordered sequences of regression. We found that problematic internet use-sex and games as well as social usage-was more prevalent in boys. Insecure peer attachment predicted problematic internet use in both sexes. Also, excessive usage of internet games and sex mediated the influence of peer attachment insecurity on problematic internet use, but only for boys. Our study identified that adolescents with insecure peer attachment are at higher risk for problematic internet use. With regard to specific types of internet use, the consumption of online games and sex was identified as risk factor in boys with increasing age. Further studies are needed to understand and possibly subgroup problematic internet use behavior in girls. Our findings suggest that increasing the quality of peer relationships may be promising approach in the prevention and treatment of problematic internet use.

People with phonologic alexia often have difficulty reading functors and verbs, in addition to pseudowords. Friedman et al (2002) reported a successful treatment for phonologic alexia that paired problematic functors and verbs with easily read relays that were homophonous nouns (e.g. "be" paired with "bee"). The current study evaluates the efficacy of pairing problematic grammatical words with relays that share initial phonemes, but vary in the relationship of their final phonemes. Results showed that reading of target grammatical words improved to criterion level (90% accuracy over two consecutive probes) in all experimental conditions with shared phonology, but remained far below criterion level in control conditions. There was a significant correlation between degree of phonologic relatedness and error rate. Maintenance of the treatment effect was poor as assessed by traditional measurement, however a dramatic savings during relearning was demonstrated during a subsequent treatment phase. The finding that reading can be re-organized by pairing target words not only with homophones, but with other phonologically related relays, suggests that this approach could be applied to a wide corpus of words and, therefore, potentially be of great use clinically. We suggest, within a connectionist account, that the treatment effect results from relays priming the initial phonologic units of the targets. PMID:18513760

In discussing issues of landscape change, the complex relationships in the landscape have to be assessed. In participative planning processes, 3D visualisations have a high potential as an aid in understanding and communicating characteristics of landscape conditions by integrating visual and non-visual landscape information. Unclear is, which design and how much interactivity is required for an indicator visualisation that would suit stakeholders best in workshop situations. This paper describes the preparation and application of three different types of integrated 3D visualisations in workshops conducted in the Entlebuch UNESCO Biosphere Reserve (CH). The results reveal that simple representations of a complex issue created by draping thematic maps on the 3D model can make problematic developments visible at a glance; that diagrams linked to the spatial context can help draw attention to problematic relationships not considered beforehand; and that the size of species as indicators of conditions of the landscape's production and biotope function seems to provide a common language for stakeholders with different perspectives. Overall, the of the indicators the functions required to assist in information processing. Further research should focus on testing the effectiveness of the integrated visualisation tools in participative processes for the general public.

Development of interpersonal relationships is a fundamental human motivation, and behaviors facilitating social bonding are prized. Some individuals experience enhanced reward from alcohol in social contexts and may be at heightened risk for developing and maintaining problematic drinking. We employed a 3 (group beverage condition) ×2 (genotype) design (N = 422) to test the moderating influence of the dopamine D4 receptor gene (DRD4 VNTR) polymorphism on the effects of alcohol on social bonding. A significant gene x environment interaction showed that carriers of at least one copy of the 7-repeat allele reported higher social bonding in the alcohol, relative to placebo or control conditions, whereas alcohol did not affect ratings of 7-absent allele carriers. Carriers of the 7-repeat allele were especially sensitive to alcohol's effects on social bonding. These data converge with other recent gene-environment interaction findings implicating the DRD4 polymorphism in the development of alcohol use disorders, and results suggest a specific pathway by which social factors may increase risk for problematic drinking among 7-repeat carriers. More generally, our findings highlight the potential utility of employing transdisciplinary methods that integrate genetic methodologies, social psychology, and addiction theory to improve theories of alcohol use and abuse.

In this paper, we investigate a new inter-channel coding mode called LM mode proposed for the next generation video coding standard called high efficiency video coding. This mode exploits inter-channel correlation using reconstructed luma to predict chroma linearly with parameters derived from neighboring reconstructed luma and chroma pixels at both encoder and decoder to avoid overhead signaling. In this paper, we analyze the LM mode and prove that the LM parameters for predicting original chroma and reconstructed chroma are statistically the same. We also analyze the error sensitivity of the LM parameters. We identify some LM mode problematic situations and propose three novel LM-like modes called LMA, LML, and LMO to address the situations. To limit the increase in complexity due to the LM-like modes, we propose some fast algorithms with the help of some new cost functions. We further identify some potentially-problematic conditions in the parameter estimation (including regression dilution problem) and introduce a novel model correction technique to detect and correct those conditions. Simulation results suggest that considerable BD-rate reduction can be achieved by the proposed LM-like modes and model correction technique. In addition, the performance gain of the two techniques appears to be essentially additive when combined.

Despite the increasing concern given to air quality in urban and industrial areas in recent years, particular emphasis on regulation, control, and reduction of air pollutant emissions is still necessary to fully characterize the chain emissions-air quality-exposure-dose-health effects, for specific sources. The Estarreja region was selected as a case study because it has one of the largest chemical industrial complexes in Portugal that has been recently expanded, together with a growing urban area with an interesting location in the Portuguese coastland and crossed by important road traffic and rail national networks. This work presents the first air quality assessment for the region concerning pollutant emissions and meteorological and air quality monitoring data analysis, over the period 2000-2009. This assessment also includes a detailed investigation and characterization of past air pollution episodes for the most problematic pollutants: ozone and PM10. The contribution of different emission sources and meteorological conditions to these episodes is investigated. The stagnant meteorological conditions associated with local emissions, namely industrial activity and road traffic, are the major contributors to the air quality degradation over the study region. A set of measures to improve air quality--regarding ozone and PM10 levels--is proposed as an air quality management strategy for the study region.

Risky individuals and the politics of genetic research into aggressiveness and violence.

Pieri, Elisa; Levitt, Mairi

2008-11-01

New genetic technologies promise to generate valuable insights into the aetiology of several psychiatric conditions, as well as a wider range of human and animal behaviours. Advances in the neurosciences and the application of new brain imaging techniques offer a way of integrating DNA analysis with studies that are looking at other biological markers of behaviour. While candidate 'genes for' certain conditions, including schizophrenia and bipolar disorders, are said to be 'un-discovered' at a faster rate than they are discovered, many studies are being conducted on personality traits such as aggressiveness and anti-social traits. The clinical applicability and implications of these studies are often discussed within the scientific community. However, little attention has so far been paid to their possible policy implications in relation to criminality management and to Criminal Law itself. Similarly, the related ethical issues arising in the field of crime control, and the tensions between enhancing security for society and protecting civil liberties, are currently under-explored. This paper investigates these ethical issues by focusing on the views of those professionals - including judges, lawyers, probation officers and social workers - who work with individuals 'deemed at risk' of violent and aggressive behaviours. It also discusses and problematizes mainstream rhetoric and arguments around the notion of 'risky individuals'.

At present, air conditioning (AC) is the most effective means for the cooling of indoor space. However, its increased global use is problematic for various reasons. This paper explores the challenges linked to increased AC use and discusses more sustainable alternatives. A literature review was conducted applying a transdisciplinary approach. It was further complemented by examples from cities in hot climates. To analyse the findings, an analytical framework was developed which considers four societal levels—individual, community, city, and national. The main challenges identified from the literature review are as follows: environmental, organisational, socio-economical, biophysical and behavioural. The paper also identifies several measures that could be taken to reduce the fast growth of AC use. However, due to the complex nature of the problem, there is no single solution to provide sustainable cooling. Alternative solutions were categorised in three broad categories: climate-sensitive urban planning and building design, alternative cooling technologies, and climate-sensitive attitudes and behaviour. The main findings concern the problems arising from leaving the responsibility to come up with cooling solutions entirely to the individual, and how different societal levels can work towards more sustainable cooling options. It is concluded that there is a need for a more holistic view both when it comes to combining various solutions as well as involving various levels in society.

Background Similarities between obsessive-compulsive disorder (OCD) and trichotillomania (TTM) have been widely recognized. Nevertheless, there is evidence of important differences between these two disorders. Some authors have conceptualized the disorders as lying on an OCD spectrum of conditions. Methods Two hundred and seventy eight OCD patients (n = 278: 148 male; 130 female) and 54 TTM patients (n = 54; 5 male; 49 female) of all ages were interviewed. Female patients were compared on select demographic and clinical variables, including comorbid axis I and II disorders, and temperament/character profiles. Results OCD patients reported significantly more lifetime disability, but fewer TTM patients reported response to treatment. OCD patients reported higher comorbidity, more harm avoidance and less novelty seeking, more maladaptive beliefs, and more sexual abuse. OCD and TTM symptoms were equally likely to worsen during menstruation, but OCD onset or worsening was more likely associated with pregnancy/puerperium. Conclusions These findings support previous work demonstrating significant differences between OCD and TTM. The classification of TTM as an impulse control disorder is also problematic, and TTM may have more in common with conditions characterized by stereotypical self-injurious symptoms, such as skin-picking. Differences between OCD and TTM may reflect differences in underlying psychobiology, and may necessitate contrasting treatment approaches. PMID:15649315

Exercise, physical activity, and exertion over the business cycle.

2013-09-01

Shifts in time and income constraints over economic expansions and contractions would be expected to affect individuals' behaviors. We explore the impact of the business cycle on individuals' exercise, time use, and total physical exertion, utilizing information on 112,000 individual records from the 2003-2010 American Time Use Surveys. In doing so, we test a key causal link that has been hypothesized in the relation between unemployment and health, but not heretofore assessed. Using more precise measures of exercise (and other activities) than previous studies, we find that as work-time decreases during a recession, recreational exercise, TV-watching, sleeping, childcare, and housework increase. This, however, does not compensate for the decrease in work-related exertion due to job-loss, and total physical exertion declines. These effects are strongest among low-educated men, which is validating given that employment in the Great Recession has declined most within manufacturing, mining, and construction. We also find evidence of intra-household spillover effects, wherein individuals respond to shifts in spousal employment conditional on their own labor supply. The decrease in total physical activity during recessions is especially problematic for vulnerable populations concentrated in boom-and-bust industries, and may have longer-term effects on obesity and related health outcomes.

Research literature on problematic smartphone use, or smartphone addiction, has proliferated. However, relationships with existing categories of psychopathology are not well defined. We discuss the concept of problematic smartphone use, including possible causal pathways to such use. We conducted a systematic review of the relationship between problematic use with psychopathology. Using scholarly bibliographic databases, we screened 117 total citations, resulting in 23 peer-reviewer papers examining statistical relations between standardized measures of problematic smartphone use/use severity and the severity of psychopathology. Most papers examined problematic use in relation to depression, anxiety, chronic stress and/or low self-esteem. Across this literature, without statistically adjusting for other relevant variables, depression severity was consistently related to problematic smartphone use, demonstrating at least medium effect sizes. Anxiety was also consistently related to problem use, but with small effect sizes. Stress was somewhat consistently related, with small to medium effects. Self-esteem was inconsistently related, with small to medium effects when found. Statistically adjusting for other relevant variables yielded similar but somewhat smaller effects. We only included correlational studies in our systematic review, but address the few relevant experimental studies also. We discuss causal explanations for relationships between problem smartphone use and psychopathology. Copyright © 2016 Elsevier B.V. All rights reserved.

The Fine-Tuning of the Universe for Intelligent Life

NASA Astrophysics Data System (ADS)

Barnes, L. A.

2012-06-01

The fine-tuning of the universe for intelligent life has received a great deal of attention in recent years, both in the philosophical and scientific literature. The claim is that in the space of possible physical laws, parameters and initial conditions, the set that permits the evolution of intelligent life is very small. I present here a review of the scientific literature, outlining cases of fine-tuning in the classic works of Carter, Carr and Rees, and Barrow and Tipler, as well as more recent work. To sharpen the discussion, the role of the antagonist will be played by Victor Stenger's recent book The Fallacy of Fine-Tuning: Why the Universe is Not Designed for Us. Stenger claims that all known fine-tuning cases can be explained without the need for a multiverse. Many of Stenger's claims will be found to be highly problematic. We will touch on such issues as the logical necessity of the laws of nature; objectivity, invariance and symmetry; theoretical physics and possible universes; entropy in cosmology; cosmic inflation and initial conditions; galaxy formation; the cosmological constant; stars and their formation; the properties of elementary particles and their effect on chemistry and the macroscopic world; the origin of mass; grand unified theories; and the dimensionality of space and time. I also provide an assessment of the multiverse, noting the significant challenges that it must face. I do not attempt to defend any conclusion based on the fine-tuning of the universe for intelligent life. This paper can be viewed as a critique of Stenger's book, or read independently.

Meaningful conversations in living with and treating chronic conditions: development of the ICAN discussion aid.

The needs of the growing population of complex patients with multiple chronic conditions calls for a different approach to care. Clinical teams need to acknowledge, respect, and support the work that patients do and the capacity they mobilize to enact this work, and to adapt and self-manage. Tools that enable this approach to care are needed. Using user-centered design principles, we set out to create a discussion aid for use by patients, clinicians, and other health professionals during clinical encounters. We observed clinical encounters, visited patient homes, and dialogued with patient support groups. We then developed and tested prototypes in routine clinical practice. Then we refined a final prototype with extensive stakeholder feedback. From this process resulted the ICAN Discussion Aid, a tool completed by the patient and reviewed during the consultation in which patients classified domains that contribute to capacity as sources of burden or satisfaction; clinical demands were also classified as sources of help or burden. The clinical review facilitated by ICAN generates hypotheses regarding why some treatment plans may be problematic and may not be enacted in the patient's situation. We successfully created a discussion aid to elucidate and share insights about the capacity patients have to enact the treatment plan and hypotheses as to why this plan may or may not be enacted. Next steps involve the evaluation of the impact of the ICAN Discussion Aid on clinical encounters with a variety of health professionals and the impact of ICAN-informed treatment plans on patient-important outcomes.

The impact of depressed mood, working memory capacity, and priming on delay discounting.

2018-09-01

The impaired ability to delay rewards, delay discounting (DD), is associated with several problematic conditions in which impulsive decision-making derails long-term goals. Working memory (WM), the ability to actively store and manipulate information, is associated with DD. The purpose of this study was to examine the effect of cognitive priming on DD and to identify moderation of this effect dependent on degree of WM capacity (WMC) and depressed mood. A WM task (n-back) was used as a cognitive prime before assessment of DD (Monetary Choice Questionnaire) and was compared to a similar prime from an inhibition task in a factorial design in 183 community participants. All participants completed a DD task and assessment of depressive symptoms (Beck Depression Inventory-II). Priming effects were evaluated relative to WMC of participants. Higher WMC and lower depression scores were associated with greater relative preference for larger, delayed rewards. The effects of a WM prime were moderated by WMC; benefits of the prime were only evident for individuals with lower WMC. No effects were found for an alternative inhibition task. Limitations included depression scores mainly in subclinical range, use of hypothetical instead of real rewards in the DD task, and no examination of the time course of effects. This study provides support for the effectiveness of a brief WM prime in enhancing ability to delay rewards. Priming may be a useful adjunctive intervention for individuals with WM dysfunction or conditions in which impulsive decision-making may derail long-term goals. Copyright © 2018.

Chantal Mouffe, along with Argentinian political theorist Ernesto Laclau (1935-2014), laid down the bases of discourse theory in 1985. She later developed her work by exploring in more detail how discourse theory formulations influence the analysis of contemporary democracies. Approaching conflict as a product of the encounter with difference, Mouffe sees it as an indelible part of the constitution of social relationships. In this encounter with the author, we seek to reflect upon certain themes and problematics that are central to her work, and upon the implications of her theory for the field of contemporary education.

Simple coupling with cosmological implications. The initial singularity and the inflationary universe

In this work the metric is coupled with a scalar field phi in a simple way. Although this coupling becomes problematic because the energy density of phi appears to be unbounded from below, it is displayed as a very simple coupling leading to a nonsingular cosmological model with an early antigravity regime. A basic study of the inflationary period and various suggestions are presented.

Violence Against Women in Cambodia: Towards a Culturally Responsive Theory of Change.

Eisenbruch, Maurice

2018-06-01

Almost one in four women in Cambodia is a victim of physical, emotional or sexual violence. This article brings together two seldom connected fields: Theory of Change (ToC) and cultural responsiveness in international development. It applies these approaches to a priority in global health, which is to prevent violence against women (VAW) and, drawing on my research on the epigenesis of VAW in Cambodia, develops an argument on the need for interventions to work with tradition and culture rather than only highlight it in problematic terms. The research draws on an ethnographic study carried out in Cambodia with 102 perpetrators and survivors of emotional, physical and sexual VAW and 228 key informants from the Buddhist and healing sectors. The eight 'cultural attractors' identified in the author's prior research highlight the cultural barriers to acceptance of the current Theory of Change. ToC for VAW prevention in Cambodia seems to assume that local culture promotes VAW and that men and women must be educated to eradicate the traditional gender norms. There is a need for interventions to work with tradition and culture rather than only highlight it in problematic terms. The cultural epigenesis of VAW in Cambodia is an insight which can be used to build culturally responsive interventions and strengthen the primary prevention of VAW.

A strong patient safety culture in the operating room (OR) and post-anesthesia care unit (PACU) is essential to promote safe care. The Patient Safety Climate in Healthcare Organizations (PSCHO) survey was administered to employees at 30 Veterans Affairs (VA) hospitals. The survey consisted of 42 close-ended items representing 12 different dimensions of safety. We measured percent problematic response (PPR); higher PPR values reflect weaker safety culture. The "OR/PACU" and the "Other Work Areas" groups' item-specific, dimension-specific, and overall problematic responses were compared. The overall and dimension-specific PPRs were similar between the OR/PACU and the Other Work Areas group (overall: 20.2% and 18.1%, respectively; P = .41). When the 2 groups were compared on an item-by-item level, the OR/PACU staff reported more frequent witnessing of unsafe patient care (PPR 55.1% vs 43.2%; P = .01), and perceived less understanding by senior leadership of clinical care (PPR 28.3% vs 17.1%; P = .01) and less hospital interest in quality of care (PPR 20.4% vs 12.5%; P = .03). Specific areas of safety culture in the OR/PACU were found that should be targeted for improvement.

Do Attachment Styles of Mentally Ill Parents Impact on the Health-related Quality of Life of their Children? Parents with a mental disorder often display a problematic attachment style which may impact on their children's health related quality of life (HrQoL). The current study cross-sectionally examines attachment styles (BEPE) in mentally ill parents with underage children (n = 62) and the effect of attachment on their children's HrQoL (KINDL-R). Results show that secure attachment is less represented in parents with a mental health condition than in a healthy reference group. Within the clinical sample, children of mentally ill parents with a secure attachment style exhibit a higher HrQoL than children of mentally ill parents with ambivalent or avoidant attachment styles. These findings indicate not only that problematic attachment styles frequently occur in families with a mentally ill parent, but also suggest that this negatively affects the children's HrQoL. Appropriate interventions should include attachment oriented concepts.

Empirical studies have identified increasing rates of Internet Gaming Disorder (IGD) and associated adverse consequences. However, very few evidence-based interventions have been evaluated for IGD or problematic video gaming behaviors. This study evaluated Mindfulness-Oriented Recovery Enhancement (MORE) as a treatment for IGD. Thirty adults (M age = 25.0, SD = 5.4) with IGD or problematic video gaming behaviors were randomized to 8 weeks of group-based MORE or 8 weeks of a support group (SG) control condition. Outcome measures were administered at pre-and posttreatment, and 3-month following treatment completion using self-report instruments. Linear mixed models were used for outcome analyses. MORE participants had significantly greater reductions in the number of DSM-5 IGD criteria they met, craving for video gaming, and maladaptive cognitions associated with gaming than SG participants, and therapeutic benefits were maintained at 3-month follow-up. MORE is a promising treatment approach for IGD. PMID:28437120

Problematic hypoglycemia, defined as two or more episodes per year of severe hypoglycemia or as one episode associated with impaired awareness of hypoglycemia, extreme glycemic lability, or major fear and maladaptive behavior, is a challenge, especially for patients with long-standing type 1 diabetes. Individualized therapy for such patients should include a composite target: optimal glucose control without problematic hypoglycemia. Therefore, we propose a tiered, four-stage algorithm based on evidence of efficacy given the limitations of educational, technological, and transplant interventions. All patients with problematic hypoglycemia should undergo structured or hypoglycemia-specific education programs (stage 1). Glycemic and hypoglycemia treatment targets should be individualized and reassessed every 3–6 months. If targets are not met, one diabetes technology—continuous subcutaneous insulin infusion or continuous glucose monitoring—should be added (stage 2). For patients with continued problematic hypoglycemia despite education (stage 1) and one diabetes technology (stage 2), sensor-augmented insulin pumps preferably with an automated low-glucose suspend feature and/or very frequent contact with a specialized hypoglycemia service can reduce hypoglycemia (stage 3). For patients whose problematic hypoglycemia persists, islet or pancreas transplant should be considered (stage 4). This algorithm provides an evidence-informed approach to resolving problematic hypoglycemia; it should be used as a guide, with individual patient circumstances directing suitability and acceptability to ensure the prudent use of technology and scarce transplant resources. Standardized reporting of hypoglycemia outcomes and inclusion of patients with problematic hypoglycemia in studies of new interventions may help to guide future therapeutic strategies. PMID:25998294

Background and aims Previous studies examined psychological factors related to treatment seeking for problematic pornography use (PU) among males. In this study, we focused on females who seek treatment for problematic PU and compared them with non-problematic pornography users with regard to variables related to problematic PU. Second, we investigated the relationships between critical constructs related to problematic PU with the path analysis method, emphasizing the predictors for treatment seeking among women. We also compared our results with previous studies on males. Methods A survey study was conducted on 719 Polish-speaking Caucasian females, 14-63 years old, including 39 treatment seekers for problematic PU. Results The positive relationship between the mere amount of PU and treatment seeking loses its significance after introducing two other predictors of treatment-seeking: religiosity and negative symptoms associated with PU. This pattern is different from the results obtained in previous studies on males. Discussion Different from previous studies on male samples, our analysis showed that in the case of women, mere amount of PU may be related to treatment-seeking behavior even after accounting for negative symptoms associated with PU. Moreover, religiousness is a significant predictor of treatment seeking among women, which may indicate that in the case of women, treatment seeking for problematic PU is motivated not only by experienced negative symptoms of PU but also by personal beliefs about PU and social norms. Conclusion For females, negative symptoms associated with PU, the amount of PU and religiosity is associated with treatment seeking. Those factors should be considered in treatment.

Cannabis is the most commonly used illegal substance among adolescents and young adults. Problematic cannabis use is often associated with comorbid psychopathological problems. The purpose of the current study was to elucidate the underlying developmental processes connecting externalizing and internalizing psychopathology in childhood and adolescence with problematic cannabis use in young adulthood. Data were drawn from the Mannheim Study of Children at Risk, an ongoing epidemiological cohort study from birth to adulthood. For n=307 participants, symptom scores of conduct/oppositional defiant disorder, attention problems, hyperactivity/impulsivity, and internalizing disorders were available for the periods of childhood (4.5-11 years) and adolescence (15 years). At age 25 years, problematic cannabis use was assessed via clinical interview and a self-rating questionnaire. At age 25 years, problematic cannabis use was identified in n=28 participants (9.1%). Childhood conduct/oppositional behavior problems were predictive of problematic cannabis use during young adulthood when comorbid symptoms were controlled for. No such effect was found for childhood attention, hyperactivity/impulsivity or internalizing problems. With respect to psychopathological symptoms during adolescence, only attention problems were significantly related to later problematic cannabis use when controlling for comorbidity. The current study highlights the role of conduct/oppositional behavior problems during childhood and attention problems during adolescence in later problematic cannabis use. It sheds more light on the developmental sequence of childhood and adolescence psychopathology and young adult cannabis use, which is a prerequisite for effective prevention approaches.

2013-08-01

The study objectives were to examine video game use in boys with autism spectrum disorder (ASD) compared with those with ADHD or typical development (TD) and to examine how specific symptoms and game features relate to problematic video game use across groups. Participants included parents of boys (aged 8-18) with ASD (n = 56), ADHD (n = 44), or TD (n = 41). Questionnaires assessed daily hours of video game use, in-room video game access, video game genres, problematic video game use, ASD symptoms, and ADHD symptoms. Boys with ASD spent more time than did boys with TD playing video games (2.1 vs 1.2 h/d). Both the ASD and ADHD groups had greater in-room video game access and greater problematic video game use than the TD group. Multivariate models showed that inattentive symptoms predicted problematic game use for both the ASD and ADHD groups; and preferences for role-playing games predicted problematic game use in the ASD group only. Boys with ASD spend much more time playing video games than do boys with TD, and boys with ASD and ADHD are at greater risk for problematic video game use than are boys with TD. Inattentive symptoms, in particular, were strongly associated with problematic video game use for both groups, and role-playing game preferences may be an additional risk factor for problematic video game use among children with ASD. These findings suggest a need for longitudinal research to better understand predictors and outcomes of video game use in children with ASD and ADHD.

The rise and growing popularity of online games has led to the appearance of excessive gaming that in some cases can lead to physical and psychological problems. Several measures have been developed to explore the nature and the scale of the phenomenon. However, few measures have been validated psychometrically. The aim of the present study was to test the psychometric properties of the 12-item Problematic Online Gaming Questionnaire Short-Form (POGQ-SF) and to assess the prevalence of problematic online gaming. Data collection was carried out to assess the prevalence of problematic online gaming in a national representative adolescent sample by using an offline (pen and pencil) method. A total of 5,045 secondary school students were assessed (51% male, mean age 16.4 years, SD=0.9 years) of which 2,804 were gamers (65.4% male, mean age 16.4 years, SD=0.9 years). Confirmatory factor analysis was applied to test the measurement model of problematic online gaming, and latent profile analysis was used to identify the proportion of gamers whose online game use can be considered problematic. Results showed that the original six-factor model yielded appropriate fit to the data, and thus the POGQ-SF has appropriate psychometric properties. Latent profile analysis revealed that 4.6% of the adolescents belong to a high risk group and an additional 13.3% to a low risk group. Due to its satisfactory psychometric characteristics, the 12-item POGQ-SF appears to be an adequate tool for the assessment of problematic online gaming.

The Yzeron periurban catchment (150 km2) is prone to flash floods leading to overflow in the downstream part of the catchment. A prevention and management plan has been approved and the set-up of a flood forecasting system is planned. The present study presents a comparison of several solutions for flood forecasting in the catchment. It is based on an extensive data collection (rain gauges, radar/rain gauge reanalyses, discharge and water level data) from this experimental catchment. A set of rainfall-runoff events leading to floods (problematic and non-problematic floods) was extracted and formed the basis for the definition of a first forecasting method. It is based on data analysis and the identification of explaining factors amongst the following: rainfall amount, intensity, antecedent rainfall, initial discharge. Several statistical methods including Factorial Analysis of Mixed Data and Classification and Regression Tree were used for this purpose. They showed that several classes of problematic floods can be identified. The first one is related to wet conditions characterized with high initial discharge and antecedent rainfall. The second class is driven by rainfall amount, initial discharge and rainfall intensity. Thresholds of these variables can be identified to provide a first warning. The second forecasting method assessed in the study is the system that will be operational in France in 2017, based on the AIGA method (Javelle et al., 2016). For this purpose, 18-year discharge simulation using the hydrological model of the AIGA method, forced using radar/rain gauges reanalysis were available at 44 locations within the catchment. The dates for which quantiles of a given return period were overtopped were identified and compared with the list of problematic events. The AIGA method was found relevant in identifying the most problematic events, but the lead time needs further investigation in order to assess the usefulness for population warning.

Background and Aims The aim of this study was to identify problematic gaming behavior among Finnish adolescents and young adults, and evaluate its connection to a variety of psychological, social, and physical health symptoms. Methods This cross-sectional study was conducted with a random sample of 293 respondents aged from 13 to 24 years. Participants completed an online survey. Problematic gaming behavior was measured with the Game Addiction Scale (GAS). Self-reports covered health measures such as psychological health (psychopathological symptoms, satisfaction with life), social health (preferences for social interaction), and physical health (general health, Body Mass Index [BMI], body discomfort, physical activity). Results Problematic gaming behavior was found to relate to psychological and health problems, namely fatigue, sleep interference, depression and anxiety symptoms. Multiple linear regression indicated that the amount of weekly gaming, depression and a preference for online social interaction predicted increased problematic gaming symptoms. Conclusions This research emphasized that problematic gaming behavior had a strong negative correlation to a variety of subjective health outcomes. PMID:26690623

Understanding risk factors of problematic gambling is prerequisite to effective intervention design to alleviate the negative consequences of gambling. This study explored the personal, social and environmental risk factors of problematic gambling in four high schools in Addis Ababa, Ethiopia, among students (N = 422) ranging from 12 to 21 years of age. Results from the cross-sectional survey showed that personal feelings (e.g., self-esteem, false perceptions about winning, drug abuse), social factors (e.g., peer influence, parental gambling), and environmental factors (e.g., accessibility of gambling venues, advertisements) were significant correlates of problematic gambling. The study also revealed that men were more at risk for severe problematic gambling than females. Among the identified types of gambling activities, the most prevalent ones were playing cards followed by flipping coin and pool gambling while internet gambling was among the least reported gambling activities. By identifying personal, social and environmental correlates of risky gambling activities this study provides evidence-based information for the systematic design and evaluation of educational interventions to prevent problematic gambling in young people.

2016-04-01

To investigate the associations between problematic mobile phone use and mental health and behavioural problems in 412 Swiss adolescents owning a mobile phone while controlling for amount of mobile phone use. Problematic mobile phone use was determined by the MPPUS-10 (Mobile Phone Problem Use Scale) and related to health and behavioural problems by means of multivariable regression modelling. MPPUS-10 was 4.7 (95 % CI 1.8, 7.6) units higher in girls than in boys, increased significantly with age and was significantly decreased with increasing educational level of the parents. Furthermore, problematic mobile phone use was associated with impaired psychological well-being, impaired parent and school relationships and more behavioural problems but was not related to peer support and social acceptance. Our study indicates that problematic mobile phone use is associated with external factors such as worse home and school environment and internal factors such as impaired mental health and behavioural problems of the adolescents and thus problematic mobile phone use should be addressed, in particular when dealing with adolescents showing behavioural or emotional problems.

The problematic use of social networking sites is becoming a major public health concern. Previous research has found that adolescents who engage in a problematic use of social networking sites are likely to show maladjustment problems. However, little is known about its links with peer aggression and victimization. The main goal of this study was to analyze the relationship between problematic use of online social networking sites, peer aggression -overt vs. relational and reactive vs. instrumental-, and peer victimization -overt physical and verbal, and relational-, taking into account gender and age (in early and mid-adolescence). Participants were selected using randomized cluster sampling considering school and class as clusters. A battery of instruments was applied to 1,952 adolescents' secondary students from Spain (Andalusia) (50.4% boys), aged 11 to 16 ( M = 14.07, SD = 1.39). Results showed that girls and 14-16 adolescents were more involved in a problematic use of online social networking sites. Furthermore, adolescents with high problematic use of online social networking sites were more involved in overt-reactive and instrumental-and relational-reactive and instrumental-aggressive behaviors, and self-reported higher levels of overt-physical and verbal-and relational victimization. Even though boys indicated higher levels of all types of victimization, girls with high problematic use of online social networking sites scored the highest on relational victimization. Relating to age, early adolescents (aged 11-14) with higher problematic use of online social networking sites reported the highest levels of overt verbal and relational victimization. Overall, results suggested the co-occurrence of problematic use of online social networking sites, peer aggression and victimization. In addition, results showed the influence that gender and age had on peer victimization. This study highlights the continuity between offline and online domains with regard to maladjustment problems in adolescence.

The aims of this study were to investigate the long-term stability of problematic gaming among adolescents and whether problematic gaming at wave 1 (W1) was associated with problem gambling at wave 2 (W2), three years later. Data from the SALVe cohort, including adolescents in Västmanland born in 1997 and 1999, were accessed and analyzed in two waves W2, N  =   1576; 914 (58%) girls). At W1, the adolescents were 13 and 15 years old, and at W2, they were 16 and 18 years old. Adolescents self-rated on the Gaming Addiction Identification Test (GAIT), Problem Gambling Severity Index (PGSI), and gambling frequencies. Stability of gaming was determined using Gamma correlation, Spearman's rho, and McNemar. Logistic regression analysis and general linear model (GLM) analysis were performed and adjusted for sex, age, and ethnicity, frequency of gambling activities and gaming time at W1, with PGSI as the dependent variable, and GAIT as the independent variable, to investigate associations between problematic gaming and problem gambling. Problematic gaming was relative stable over time, γ = 0.739, p  ≤   .001, ρ = 0.555, p  ≤   .001, and McNemar p  ≤   .001. Furthermore, problematic gaming at W1 increased the probability of having problem gambling three years later, logistic regression OR = 1.886 (95% CI 1.125-3.161), p  =   .016, GLM F  = 10.588, η 2  = 0.007, p =  .001. Problematic gaming seems to be relatively stable over time. Although associations between problematic gaming and later problem gambling were found, the low explained variance indicates that problematic gaming in an unlikely predictor for problem gambling within this sample.

2011-11-01

Artificial neural networks (ANNs) have been used for the recognition of non-linear patterns, a characteristic of bioprocesses like wine production. In this work, ANNs were tested to predict problems of wine fermentation. A database of about 20,000 data from industrial fermentations of Cabernet Sauvignon and 33 variables was used. Two different ways of inputting data into the model were studied, by points and by fermentation. Additionally, different sub-cases were studied by varying the predictor variables (total sugar, alcohol, glycerol, density, organic acids and nitrogen compounds) and the time of fermentation (72, 96 and 256 h). The input of data by fermentations gave better results than the input of data by points. In fact, it was possible to predict 100% of normal and problematic fermentations using three predictor variables: sugars, density and alcohol at 72 h (3 days). Overall, ANNs were capable of obtaining 80% of prediction using only one predictor variable at 72 h; however, it is recommended to add more fermentations to confirm this promising result.

Several studies suggest that Asian countries are particularly afflicted by problematic Internet use (PIU). The present study investigates whether individual differences in the acceptance of power distance can be linked to overuse of the Internet in Germany and in China. Power distance has been discussed as an essential dimension on which Asian and Western societies differ. In the present study, we investigate two large non-clinical samples from Germany (n = 297) and China (n = 556) to address this question. Both in Germany and in China, high acceptance of power distance was positively associated with PIU. These effects were more pronounced in China compared with Germany. Moreover, the observed effects were stronger in males compared with females. Clearly, these findings are just a starting point and need to be replicated in the future. Clinical populations and a further important difference variable - collectivism - also merit consideration in future work. © 2015 Wiley Publishing Asia Pty Ltd.

The aim of the present study was to investigate associations between problematic gaming and psychiatric symptoms among adolescents. Data from adolescents in the SALVe cohort, including adolescents in Västmanland who were born in 1997 and 1999 (N=1868; 1034 girls), and data from consecutive adolescent psychiatric outpatients in Västmanland (N=242; 169 girls) were analyzed. Adolescents self-rated on the Gaming Addiction Identification Test (GAIT), Adult ADHD Self-Report Scale Adolescent version (ASRS-A), Depression Self-Rating Scale Adolescent version (DSRS-A), Spence Children's Anxiety Scale (SCAS), and psychotic-like experiences (PLEs). Multivariable logistic regression analyses were performed, and adjusted for sex, age, study population, school bullying, family maltreatment, and interactions by sex, with two-way interactions between psychiatric measurements. Boys had higher self-rated problematic gaming in both samples, whereas girls self-rated higher in all psychiatric domains. Boys had more than eight times the probability, odds ratio (OR), of having problematic gaming. Symptoms of ADHD, depression and anxiety were associated with ORs of 2.43 (95% CI 1.44-4.11), 2.47 (95% CI 1.44-4.25), and 2.06 (95% CI 1.27-3.33), respectively, in relation to coexisting problematic gaming. Problematic gaming was associated with psychiatric symptoms in adolescents; when problematic gaming is considered, the probability of coexisting psychiatric symptoms should also be considered, and vice versa.

Anxiety disorders are highly prevalent, affecting approximately 10% of individuals throughout life; its onset can be detected since early childhood or adolescence. Studies in adults have shown that anxiety disorders are associated with alcohol abuse, but few studies have investigated the association between anxiety symptoms and problematic alcohol use in early ages. To evaluate if anxiety symptoms are associated with problematic alcohol use in young subjects. A total of 239 individuals aged 10-17 years were randomly selected from schools located in the catchment area of Hospital de Clínicas de Porto Alegre. The Screen for Child Anxiety-Related Emotional Disorders (SCARED) was used to evaluate the presence of anxiety symptoms, and the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), to evaluate alcohol use. One hundred twenty-seven individuals (53.1% ) reported having already used alcohol. Of these, 14 individuals showed problematic alcohol use (5.8% ). There was no association between lifetime use of alcohol and anxiety symptoms, but mean SCARED scores in individuals with problematic alcohol use was higher if compared to those without problematic use, even after adjustment for age and gender (29.9±8.5 vs. 23.7±11.8, p < 0.001). Despite the limitation of a cross-sectional design, our study suggests that anxiety symptoms are associated with problematic alcohol use early in life.

Smartphones are becoming a daily necessity for most undergraduates in Mainland China. Because the present scenario of problematic smartphone use (PSU) is largely unexplored, in the current study we aimed to estimate the prevalence of PSU and to screen suitable predictors for PSU among Chinese undergraduates in the framework of the stress-coping theory. A sample of 1062 undergraduate smartphone users was recruited by means of the stratified cluster random sampling strategy between April and May 2015. The Problematic Cellular Phone Use Questionnaire was used to identify PSU. We evaluated five candidate risk factors for PSU by using logistic regression analysis while controlling for demographic characteristics and specific features of smartphone use. The prevalence of PSU among Chinese undergraduates was estimated to be 21.3%. The risk factors for PSU were majoring in the humanities, high monthly income from the family (≥1500 RMB), serious emotional symptoms, high perceived stress, and perfectionism-related factors (high doubts about actions, high parental expectations). PSU among undergraduates appears to be ubiquitous and thus constitutes a public health issue in Mainland China. Although further longitudinal studies are required to test whether PSU is a transient phenomenon or a chronic and progressive condition, our study successfully identified socio-demographic and psychological risk factors for PSU. These results, obtained from a random and thus representative sample of undergraduates, opens up new avenues in terms of prevention and regulation policies.

The role of language in suicide reporting: Investigating the influence of problematic suicide referents.

Although suicide experts recommend using neutral suicide referents in news media reporting, this recommendation has not yet been tested empirically. This recommendation, based on the empirically yet untested assumption that problematic suicide referents carry meaning that is inappropriate from a prevention perspective, may lead to a different perspective on suicide, termed "framing effects." For example, in German-speaking countries, the neutral term Suizid (suicide) is recommended. Conversely, Freitod ("free death") and Selbstmord ("self-murder") convey associative meanings related to problematic concepts such as free will (Freitod) and crime/murder (Selbstmord), and are therefore not recommended. Using a web-based randomized controlled trial focused on German speakers (N = 451), we tested whether the news media's use of Suizid, Selbstmord, and Freitod elicits framing effects. Participants read identical news reports about suicide. Only the specific suicide referents varied depending on the experimental condition. Post-reading, participants wrote short summaries of the news reports, completed a word-fragment completion test and a questionnaire targeting suicide-related attitudes. We found that the news frame primed some frame-related concepts in the memory and also increased frame-related word choice. Importantly, we found that participants reading the free will-related Freitod frame showed greater attitudinal support for suicide among individuals suffering from incurable diseases. This study highlights the importance of how the news media write about suicide and supports the language recommendations put forward by suicide experts. Copyright © 2018 Elsevier Ltd.

Work is central to well-being but working is problematic when people experience workplace bullying, which includes psychological, physical, and sexual abuse or harassment. The purpose of the present grounded theory study was to extend current understanding, from the perspective of women, of how workplace bullying affects their work and how they engage in the workforce. The study was conducted in eastern Canada with 36 English-speaking women who had been bullied in the workplace. They reported mainly psychological bullying. The central problem for women is they cannot continue working as they had before the workplace bullying. The authors named a four-stage process of how women address this problem as "Doing Work Differently." The four stages are Being Conciliatory, Reconsidering, Reducing Interference, and Redeveloping Balance. The process is influenced by women's support systems, the effects on their health, and financial circumstances. There are implications for public education, workplace policies, and health care workers.

Problematic Internet use (PIU) and problematic alcohol use are two pervasive problems during adolescence that share similar characteristics and predictors. The first objective of this study was to analyze the temporal and reciprocal relationships among the main components of PIU from the cognitive-behavioral model (preference for online social interaction, mood regulation through the Internet, deficient self-regulation, and negative consequences). The second objective was to examine the temporal and reciprocal relationships between PIU components and problematic alcohol use. We also examined whether these relationships differ between males and females. The sample comprised 801 Spanish adolescents (mean age=14.92, SD=1.01) who completed the measures both at Time 1 (T1) and Time 2 (T2) six months apart. We used structural equation modeling to analyze the relationship among the variables. Results showed that deficient self-regulation at T1 predicted an increase in preference for online interactions, mood regulation, and negative consequences of the Internet at T2. In turn, the emergence of negative consequences of PIU at T1 predicted a rise in problematic alcohol use at T2. Longitudinal relationships between different components of PIU and between the components of PIU and problematic alcohol use were invariant across genders. Deficient self-regulation, consisting of diminished self-control over cognition and behaviors related to the Internet, plays a central role in the maintenance of PIU, increasing the preference for online interactions, mood regulation, and negative consequences from Internet use over time. In turn, adolescents who present negative consequences of PIU are vulnerable targets for problematic alcohol use. Copyright © 2014 Elsevier Ltd. All rights reserved.

Abstract The rise and growing popularity of online games has led to the appearance of excessive gaming that in some cases can lead to physical and psychological problems. Several measures have been developed to explore the nature and the scale of the phenomenon. However, few measures have been validated psychometrically. The aim of the present study was to test the psychometric properties of the 12-item Problematic Online Gaming Questionnaire Short-Form (POGQ-SF) and to assess the prevalence of problematic online gaming. Data collection was carried out to assess the prevalence of problematic online gaming in a national representative adolescent sample by using an offline (pen and pencil) method. A total of 5,045 secondary school students were assessed (51% male, mean age 16.4 years, SD=0.9 years) of which 2,804 were gamers (65.4% male, mean age 16.4 years, SD=0.9 years). Confirmatory factor analysis was applied to test the measurement model of problematic online gaming, and latent profile analysis was used to identify the proportion of gamers whose online game use can be considered problematic. Results showed that the original six-factor model yielded appropriate fit to the data, and thus the POGQ-SF has appropriate psychometric properties. Latent profile analysis revealed that 4.6% of the adolescents belong to a high risk group and an additional 13.3% to a low risk group. Due to its satisfactory psychometric characteristics, the 12-item POGQ-SF appears to be an adequate tool for the assessment of problematic online gaming. PMID:23621688

Firefighters are at increased risk for both problematic alcohol use and suicidality. Research has found that problematic alcohol use is related to suicidality among this population; however, limited data exist regarding what might account for this association. The present two-study investigation (1) examined the association between suicidality and problematic alcohol use among two large samples of firefighters and (2) tested whether interpersonal theory of suicide constructs-perceived burdensomeness (PB) and thwarted belongingness (TB)-serve as indirect indicators of this relationship. Participants in Study 1 were 944 U.S. firefighters (12.5% female); participants in Study 2 were 241 U.S. women firefighters. Participants completed the Interpersonal Needs Questionnaire, Alcohol Use Disorders Identification Test, and the Depressive Symptom Inventory-Suicidality Subscale (Study 1) or the Self-Injurious Thoughts and Behaviors Interview-Short Form (Study 2). Bias-corrected bootstrap indirect effects path analyses were utilized. In Study 1, more problematic alcohol use was significantly associated with more severe career suicidal ideation via PB but not TB. In Study 2, problematic alcohol use was associated with career suicidal ideation via both PB and TB. PB seems to account for the relationship between problematic alcohol use and career suicidal ideation among male and female firefighters. Limitations include use of a cross-sectional design, use of retrospective measures of suicidal ideation, and our findings derived from subsamples of two existing datasets. Findings suggest that PB and TB may explain the relationship between problematic alcohol use and suicidal ideation, but that this effect is discrepant based on gender. Copyright © 2018.

Human errors occur everywhere, including in health care. Not only the patient, but also the involved health professional is affected (ie, the "second victim"). To investigate the prevalence of health care professionals being personally involved in a patient safety incident (PSI), as well as the relationship of involvement and degree of harm with problematic medication use, excessive alcohol consumption, risk of burnout, work-home interference (WHI), and turnover intentions. Multilevel path analyses were conducted to analyze cross-sectional survey data from 37 Belgian hospitals. A total of 5788 nurses (79.4%) and physicians (20.6%) in 26 acute and 11 psychiatric hospitals were included. "Involvement in a patient safety incident during the prior 6 months," "degree of harm," and 5 outcomes were measured using self-report scales. Nine percent of the total sample had been involved in a PSI during the prior 6 months. Involvement in a PSI was related to a greater risk of burnout (β=0.40, OR=2.07), to problematic medication use (β=0.33, OR=1.84), to greater WHI (β=0.24), and to more turnover intentions (β=0.22). Harm to the patient was a predictor of problematic medication use (β=0.14, OR=1.56), risk of burnout (β=0.16, OR=1.62), and WHI (β=0.19). Second victims experience significant negative outcomes in the aftermath of a PSI. An appropriate organizational response should be provided to mitigate the negative effects.

For many individuals, excessive smartphone use interferes with everyday life. In the present study, we recruited a non-clinical sample of 296 participants for a cross-sectional survey of problematic smartphone use, social and non-social smartphone use, and psychopathology-related constructs including negative affect, fear of negative and positive evaluation, and fear of missing out (FoMO). Results demonstrated that FoMO was most strongly related to both problematic smartphone use and social smartphone use relative to negative affect and fears of negative and positive evaluation, and these relations held when controlling for age and gender. Furthermore, FoMO (cross-sectionally) mediated relations between both fear of negative and positive evaluation with both problematic and social smartphone use. Theoretical implications are considered with regard to developing problematic smartphone use. Copyright © 2017 Elsevier B.V. All rights reserved.

Problematic or addictive digital gaming (including all types of electronic devices) can and has had extremely adverse impacts on the lives of many individuals across the world. The understanding of this phenomenon, and the effectiveness of treatment design and monitoring, can be improved considerably by continuing refinement of assessment tools. The present article briefly overviews tools designed to measure problematic or addictive use of digital gaming, the vast majority of which are founded on the Diagnostic and Statistical Manual of Mental Disorders (DSM) criteria for other addictive disorders, such as pathological gambling. Although adapting DSM content and strategies for measuring problematic digital gaming has proven valuable, there are some potential issues with this approach. We discuss the strengths and limitations of current methods for measuring problematic or addictive gaming and provide various recommendations that might help in enhancing or supplementing existing tools, or in developing new and even more effective tools.

This research aims to study the existing relationships among the factors of state anxiety, depression, impulsivity, and alcohol consumption regarding problematic mobile phone use, as assessed by the Mobile Phone Problem Use Scale. The study was conducted among 1,126 participants recruited among the general Spanish population, aged 16–65 years, by assessing the predictive value of these variables regarding this problematic use. Initially tobacco use was also considered being subsequently refused because of the low internal consistency of the scale used. In general terms, the results show that this problematic use is mainly related to state anxiety and impulsivity, through the dimensions of Positive and Negative Urgency. Considering its predictive value, multiple regression analysis reveals that state anxiety, positive and negative urgency, and alcohol consumption may predict problematic mobile phone use, ruling out the influence of depression.

2016-01-01

In this study, the relationships among problematic mobile phone use, age, gender, personality and chronotype of Turkish university students were examined. The study included 902 university students (73% female, 27% male) and their participation in the study was anonymous and voluntary. Data were collected from each participant by assessing a demographic questionnaire, Composite Scale of Morningness (CSM) as a measure of chronotype, the Big Five Inventory (BIG-5) for personality assessment and Mobile Phone Problem Usage Scale (MPPUS). The most important result was that CSM scores were the best predictor for problematic mobile phone usage, and as a consequence, evening-oriented university students scored higher on the MPPUS. This result remained, even when compared with the most influential personality predictor, conscientiousness. In addition, while extraversion positively predicted, emotional stable and chronotype negatively predicted problematic mobile phone use. Lastly, age and gender were not predictors of problematic mobile phone use.

Problematic use of the mobile telephone is an emerging phenomenon in our society, and one which particularly affects the teenage population. Knowledge from research on the problematic use of this technology is necessary, since such use can give rise to a behavioural pattern with addictive characteristics. There are hardly any scales for measuring possible problematic use of mobile phones, and none at all adapted exclusively for the Spanish adolescent population. The scale most widely used internationally is the Mobile Phone Problem Use Scale (MPPUS). The aim of the present study is to adapt the MPPUS for use with Spanish adolescents. The Spanish version of the questionnaire was administered to a sample of 1132 adolescents aged 12 to 18. Reliability and factorial validity were comparable to those obtained in adult population, so that the measure of problematic mobile phone use in Spanish teenagers is one-dimensional. A prevalence of 14.8% of problematic users was detected.

[Self-disclosure on the Net: A risk factor for problematic use of the Internet among insecure persons].

PubMed

Danet, M; Miljkovitch, R

2016-12-01

Problematic use of the Internet (PUI) is more and more commonly seen among psychiatry patients. PUI is defined as an excessive preoccupation about and use of the Internet, which can be characterized by more time spent on-line than what was planned, with difficulties leading to distress or significant disorders. The new mode of interaction provided by the Internet facilitates self-disclosure, especially for socially anxious persons who feel safer and more comfortable in on-line compared with face-to-face interactions. Several studies point to the fact that insecure attachment, and particularly preoccupied attachment, is associated with problematic use of the Internet. Preoccupied attachment is characterized by a negative model of self and a positive model of others. Persons with a negative model of self feel anxious in interpersonal relationships. Because self-disclosure is easier on-line, it may play a role in problematic use of the Internet. The aim of the study is to better understand the link between insecure attachment and problematic use of the Internet, by examining the mediating role of self-disclosure. Participants anonymously completed the following self-questionnaires on-line: the Internet Addiction Test (IAT), which assesses problematic use of the Internet, the Relationship Scale Questionnaire (RSQ), which evaluates attachment, and the "Real-me" questionnaire, which measures increased self-disclosure on the Internet compared with face-to-face interactions. Participants (n=200, 73 % women) were recruited via e-mails, social networks, ads in local stores and leaflets in public places, directing them towards a link in which they could complete the on-line questionnaires. Descriptive analyses were conducted to examine the main characteristics of participants. A t-test was used to explore gender differences. Main analyses consisted of correlational analyses between attachment, the "Real-me", and problematic use of the Internet. A series of regression analyses were then used to test the mediating role of the "Real-me" in the link between insecure attachment and problematic use of the Internet. Results confirm the associations between problematic use of the Internet and, respectively, preoccupied and fearful attachment. Complete mediation of the "Real-me" in the association between negative model of self (attachment) and problematic use of the Internet was also confirmed. Preoccupied and fearful attachments are both associated with problematic use of the Internet. These persons have a negative model of self which may hamper their ability to be at ease in face-to-face interactions. Being themselves on the Internet mediates the link between negative model of self and problematic use of the Internet. Resorting to a less threatening environment of exchange may thus explain these insecure individuals' tendency to overuse the Internet. Future research investigating the different activities on the Internet would be useful to better determine whether certain specific activities are more closely linked to problematic use of the Internet among insecure individuals.

Zavala, Egbert

2017-10-17

While a number of studies have attributed critical incident stressors to alcohol abuse among police officers, no study has examined the role gambling, if any, plays on problematic alcohol consumption. Therefore, data from the Police Stress and Domestic Violence in Police Families in Baltimore, Maryland, 1997-1999 are analyzed to test the influence of gambling on problematic alcohol consumption engaged by police officers. Results indicated that gambling is significant in predicting problematic alcohol consumption. Burnout, peer drinking, and self-control also predicted the dependent variable. The study's results, as well as the study's limitations and directions for future research, are also discussed.

This systematic review and meta-analysis aimed to investigate the interplay between problematic gaming behaviour and health-related outcomes at different developmental stages. A total of 50 empirical studies met the specified inclusion criteria, and a meta-analysis using correlation coefficients was used for the studies that reported adverse health implications regarding the impact of problematic gaming behaviour on depression, anxiety, obsessive-compulsive disorder and somatisation. Overall, the results suggested that problematic gaming behaviour is significantly associated with a wide range of detrimental health-related outcomes. Finally, the limitations of this review alongside its implications were discussed and considered for future research.

The association between psychological well-being and problematic use of Internet communicative services among young people.

Casale, Silvia; Lecchi, Stefano; Fioravanti, Giulia

2015-01-01

Previous studies on problematic Internet use have focused almost exclusively on the fact that presence of negative functioning, such as social anxiety, depressive symptoms, or loneliness, represents a risk factor for unhealthy use of the web. For this reason the aim of the present study was to investigate the association between psychological well-being dimensions and problematic use of Internet communicative services. In the current study 495 undergraduate students were recruited. The Italian adaptations of the Psychological Well-being Scales and the Generalized Problematic Internet Use Scale 2 (GPIUS2) were used to assess psychological well-being dimensions and generalized problematic Internet use, respectively. Psychological well-being dimensions explained a significant portion of variance for the GPIUS2 total score levels, after controlling for sex, age, and occupational status. The levels of Autonomy, Environmental Mastery, and Positive Relations with Others acted as significant negative predictors of the tendency to use the web for regulating negative feelings, compulsive use of the web, and the negative outcomes that can arise as a result. The overall findings of the present study provide preliminary evidence that low psychological well-being is associated with problematic use of Internet communicative services.

Ethics of the electrified mind: Defining issues and perspectives on the principled use of brain stimulation in medical research and clinical care

PubMed Central

Cabrera, Laura Y.; Evans, Emily L.; Hamilton, Roy H.

2013-01-01

In recent years, non-pharmacologic approaches to modifying human neural activity have gained increasing attention. One of these approaches is brain stimulation, which involves either the direct application of electrical current to structures in the nervous system or the indirect application of current by means of electromagnetic induction. Interventions that manipulate the brain have generally been regarded as having both the potential to alleviate devastating brain-related conditions and the capacity to create unforeseen and unwanted consequences. Hence, although brain stimulation techniques offer considerable benefits to society, they also raise a number of ethical concerns. In this paper we will address various dilemmas related to brain stimulation in the context of clinical practice and biomedical research. We will survey current work involving deep brain stimulation (DBS), transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS). We will reflect upon relevant similarities and differences between them, and consider some potentially problematic issues that may arise within the framework of established principles of medical ethics: nonmaleficence and beneficence, autonomy, and justice.

Case study of open-source enterprise resource planning implementation in a small business

NASA Astrophysics Data System (ADS)

Olson, David L.; Staley, Jesse

2012-02-01

Enterprise resource planning (ERP) systems have been recognised as offering great benefit to some organisations, although they are expensive and problematic to implement. The cost and risk make well-developed proprietorial systems unaffordable to small businesses. Open-source software (OSS) has become a viable means of producing ERP system products. The question this paper addresses is the feasibility of OSS ERP systems for small businesses. A case is reported involving two efforts to implement freely distributed ERP software products in a small US make-to-order engineering firm. The case emphasises the potential of freely distributed ERP systems, as well as some of the hurdles involved in their implementation. The paper briefly reviews highlights of OSS ERP systems, with the primary focus on reporting the case experiences for efforts to implement ERPLite software and xTuple software. While both systems worked from a technical perspective, both failed due to economic factors. While these economic conditions led to imperfect results, the case demonstrates the feasibility of OSS ERP for small businesses. Both experiences are evaluated in terms of risk dimension.

Anxious, threatened, and also unethical: how anxiety makes individuals feel threatened and commit unethical acts.

PubMed

Kouchaki, Maryam; Desai, Sreedhari D

2015-03-01

People often experience anxiety in the workplace. Across 6 studies, we show that anxiety, both induced and measured, can lead to self-interested unethical behavior. In Studies 1 and 2, we find that compared with individuals in a neutral state, anxious individuals are more willing (a) to participate in unethical actions in hypothetical scenarios and (b) to engage in more cheating to make money in situations that require truthful self-reports. In Studies 3 and 4, we explore the psychological mechanism underlying unethical behaviors when experiencing anxiety. We suggest and find that anxiety increases threat perception, which, in turn, results in self-interested unethical behaviors. Study 5 shows that, relative to participants in the neutral condition, anxious individuals find their own unethical actions to be less problematic than similar actions of others. In Study 6, data from subordinate-supervisor dyads demonstrate that experienced anxiety at work is positively related with experienced threat and unethical behavior. We discuss the theoretical and practical implications of our findings. PsycINFO Database Record (c) 2015 APA, all rights reserved.

Extreme premature child's long-term prognostic is getting better and better known, and if a resuscitation procedure is possible at birth, it won't guarantee survival or a survival free of disability. Incertitude toward individual prognosis and outcome for those children remains considerable. In this field, we are at the frontier of medical knowledge and the answer to the question, "how to decide the ante and postnatal care" is crucial. This work is focused on this problematic of decision-making in the context of extreme prematurity. It attempts to deconstruct this concept and to explicit its stakes. Thus, with the support of the medical sources and of philosophical debates, we tried to build a decision-making procedure that complies with the ethical requirements of medical care, accuracy, justice and equity. This decision-making procedure is primarily concerned with the singularity of each decision situation and it intends to link it closely to the notions of rationality and responsibility.

Analysis of nutritional disease in prehistory: The search for scurvy in antiquity and today.

In this paper, we discuss the issues surrounding the study of scurvy, or vitamin C deficiency, in paleopathology, and highlight the work of Donald Ortner in advancing this area of research. This micronutrient deficiency impacts collagen formation and results in damage to a variety of bodily tissues. While clinical manifestations are observed routinely, the lack of specific signatures on bone makes paleopathological diagnosis difficult. Rapid growth in infants, children, and subadults provides abundant remodeled tissue and an increase in vascularization that makes identification possible in younger segments of the population. However, diagnosis of scurvy in adults remains problematic, given that diagnostic lesions are strikingly similar to those associated with rickets, osteomalacia, and other conditions. We argue that this confounding factor underscores the need for a broader anthropological approach to scurvy research that expands beyond differential diagnosis to include more accurate reconstruction of diets and available resources, greater consideration of the possibility - even likelihood - of multiple nutrient deficiencies simultaneously affecting an individual, and the patterning of these deficiencies along lines of status, sex, and age.

Working across boundaries of power, identity, and political geography is fraught with difficulties and contradictions. In Tali Tal and Iris Alkaher's, " Collaborative environmental projects in a multicultural society: Working from within separate or mutual landscapes?" the authors describe their efforts to do this in the highly charged atmosphere of Israel. This forum article offers a response to their efforts. Writing from a framework of critical pedagogy, I use the concepts of space and time to anchor my analysis, as I examine the issue of power in this Jew/Arab collaborative environmental project. This response problematizes "sharing" in a landscape fraught with disparities. It also looks to further Tal and Alkaher's work by geographically and politically grounding it in the broader current conflict and by juxtaposing sustainability with equity.

The association of sexual victimization with self-esteem, depression, and problematic internet use was examined in Korean adolescents. A total of 695 middle and high school students were recruited (413 boys, 282 girls, mean age, 14.06±1.37 years). The participants were administered the Early Trauma Inventory Self Report-Short Form (ETISR-SF), Rosenberg's Self-Esteem Scale (RSES), the Children's Depression Inventory (CDI), and Young's Internet Addiction Test (IAT). The associations between sexual abuse and the level of self-esteem, depressive symptoms, and problematic internet use were analyzed. Adolescents who had experienced sexual abuse showed lower self-esteem, more depressive symptoms, and greater problematic internet use compared with adolescents who had not experienced sexual abuse. In the path model, sexual abuse predicted lower self-esteem (β=-0.11; 95% CI=-0.20, -0.04; p=0.009), which predicted higher depressive symptoms (β=-0.34; 95% CI=-0.40, -0.27; p=0.008). Depressive symptoms predicted problematic internet use in a positive way (β=0.23; 95% CI=0.16–0.29; p=0.013). Sexual abuse also predicted problematic internet use directly (β=0.20; 95% CI=0.12–0.27; p=0.012). The results of the present study indicate that sexually abused adolescents had a higher risk of depression and problematic internet use. For sexually abused adolescents, programs aimed at raising self-esteem and preventing internet addiction, as well as mental health screening, are needed. PMID:28539957

Background Because cannabis use is associated with social, physical and psychological problems, it is important to know what causes some individuals to initiate cannabis use and a subset of those to become problematic users. Previous twin studies found evidence for both genetic and environmental influences on vulnerability, but due to considerable variation in the results it is difficult to draw clear conclusions regarding the relative magnitude of these influences. Method A systematic literature search identified 28 twin studies on cannabis use initiation and 24 studies on problematic cannabis use. The proportion of total variance accounted for by genes (A), shared environment (C), and unshared environment (E) in (1) initiation of cannabis use and (2) problematic cannabis use was calculated by averaging corresponding A, C, and E estimates across studies from independent cohorts and weighting by sample size. Results For cannabis use initiation, A, C, and E estimates were 48%, 25% and 27% in males and 40%, 39% and 21% in females. For problematic cannabis use A, C, and E estimates were 51%, 20% and 29% for males and 59%, 15% and 26% for females. Confidence intervals of these estimates are considerably narrower than those in the source studies. Conclusions Our results indicate that vulnerability to both cannabis use initiation and problematic use was significantly influenced by A, C, and E. There was a trend for a greater C and lesser A component for cannabis initiation as compared to problematic use for females. PMID:20402985

Background Linkages between intrauterine exposures to cocaine and marijuana and adolescents’ problematic substance use have not been fully delineated. Methods Prospective longitudinal study with assessors unaware of intrauterine exposure history followed 157 urban participants from birth until late adolescence. Level of intrauterine exposures was identified by mother's report and infant’s meconium. Problematic substance use, identified by the Voice Diagnostic Interview Schedule for Children (V-DISC) or the Audio Computer Assisted Self-Interview (ACASI) and urine assay, was a composite encompassing DSM-IV indication of tolerance, abuse, and dependence on alcohol, marijuana, and tobacco and any use of cocaine, glue, or opiates. Results Twenty percent (32/157) of the sample experienced problematic substance use by age 18 years, of whom the majority (22/157) acknowledged abuse, tolerance or dependence on marijuana with or without other substances. Structural equation models examining direct and indirect pathways linking a Cox survival model for early substance initiation to a logistic regression models found effects of post-natal factors including childhood exposure to violence and household substance use, early youth substance initiation, and ongoing youth violence exposure contributing to adolescent problematic substance use. Conclusion We did not identify direct relationships between intrauterine cocaine or marijuana exposure and problematic substance use, but did find potentially modifiable post-natal risk factors also noted to be associated with problematic substance use in the general population including earlier substance initiation, exposure to violence and to household substance use.

Staff shortages could harm the provision and quality of health care in Uganda, so staff retention and motivation are crucial. Understanding the impact of HIV/AIDS on staff contributes to designing appropriate retention and motivation strategies. This research aimed 'to identify the influence of HIV/AIDS on staff working in general hospitals at district level in rural areas and to explore support required and offered to deal with HIV/AIDS in the workplace'. Its results were to inform strategies to mitigate the impact of HIV/AIDS on hospital staff. A cross-sectional study with qualitative and quantitative components was implemented during two weeks in September 2005. Data were collected in two government and two faith-based private not-for-profit hospitals purposively selected in rural districts in Uganda's Central Region. Researchers interviewed 237 people using a structured questionnaire and held four focus group discussions and 44 in-depth interviews. HIV/AIDS places both physical and, to some extent, emotional demands on health workers. Eighty-six per cent of respondents reported an increased workload, with 48 per cent regularly working overtime, while 83 per cent feared infection at work, and 36 per cent reported suffering an injury in the previous year. HIV-positive staff remained in hiding, and most staff did not want to get tested as they feared stigmatization. Organizational responses were implemented haphazardly and were limited to providing protective materials and the HIV/AIDS-related services offered to patients. Although most staff felt motivated to work, not being motivated was associated with a lack of daily supervision, a lack of awareness on the availability of HIV/AIDS counselling, using antiretrovirals and working overtime. The specific hospital context influenced staff perceptions and experiences. HIV/AIDS is a crucially important contextual factor, impacting on working conditions in various ways. Therefore, organizational responses should be integrated into responses to other problematic working conditions and adapted to the local context. Opportunities already exist, such as better use of supervision, educational sessions and staff meetings. However, exchanges on interventions to improve staff motivation and address HIV/AIDS in the health sector are urgently required, including information on results and details of the context and implementation process.

There has been a long-standing need for a diagnostic manual that documents the unique pathological behaviors of lesbians. The Dyke Diagnostic Manual (DDM) is meant to supplement mainstream classification systems used to identify problematic behaviors in heterosexuals. This article presents thirteen uniquely lesbian conditions that are nowhere to be found in heterosexist diagnostic systems. The DDM may help to reduce the pain and suffering found in many lesbian relationships where one or both partners are afflicted.

Possible articulatory and auditory contributions to explanation of the observed patterns are discussed.

How organizational research can avoid the pitfalls of a co-optation perspective: analyzing gender equality work in Austrian universities with organizational institutionalism.

PubMed

2017-04-03

The concept of co-optation offers vocabulary to discuss how concerns and demands of feminist movements are transformed on their way to, and within, mainstream organizations and policymaking. However, applications of this concept can have problematic implications, failing to grasp the complexity of social change efforts and contributing to divisions, rather than alliances, between different groups that work and fight for gender equality. This article argues that conceptual tools from organizational institutionalism can help to avoid these pitfalls by capturing the ambivalence of organizational change initiatives, and allowing us to identify not only counterintentional effects, but also subtle and unexpected opportunities of organizational gender equality work. I illustrate my arguments with empirical examples from research on gender equality work in Austrian universities.

Legislative epidemics: the role of model law in the transnational trend to criminalise HIV transmission.

PubMed

Grace, Daniel

2013-12-01

HIV-related state laws are being created transnationally though the use of omnibus model laws. In 2004, the US Agency for International Development (USAID) funded the creation of one such guidance text known as the USAID/Action for West Africa Region Model Law, or N'Djamena Model Law, which led to the rapid spread of HIV/AIDS laws, including the criminalisation of HIV transmission, across much of West and Central Africa (2005-2010). In this article, I explicate how an epidemic of highly problematic legislation spread across the region as a result of a text-mediated work process enabled through model laws. I theorise the textual genre of model laws arguing that these texts are best understood as 'preoperative documents' which, when activated, can lead to swift legislative reform in and beyond the field of HIV/AIDS governance. The legislative process being investigated was made visible through participant observation, archival research, textual analysis and informant interviews with national and international stakeholders (n=32). This involved ethnographic research in Canada, the USA, Switzerland, Austria, South Africa and Senegal (2010-2011). The untold policy processes and narratives explored in this article make evident how the work of contesting problematic HIV/AIDS model laws and newly drafted state laws involves both creating new texts and contesting the legitimacy and efficacy of others.

Hospitals in Germany employ increasing numbers of foreign-born and foreign-trained (FB&FT) physicians. Studies have investigated how FB&FT physicians experience their professional integration into the German healthcare system, however, the perspectives of stakeholders working with and shaping the work experiences of FB&FT physicians in German hospitals have so far been neglected. This study explores relevant stakeholders' opinions and attitudes towards FB&FT physicians-which likely influence how these physicians settle in-and how these opinions were formed. We conducted a qualitative interview study with 25 stakeholders working in hospitals or in health policy development. The interviews were analyzed within a constructivist research paradigm using methods derived from Grounded Theory (situational analysis as well as open, axial and selective coding). We found that stakeholders tended to focus on problems in FB&FT physicians' work performance. Participants criticized FB&FT physicians' work for deviating from presumably shared professional standards (skill or knowledge and behavioral standards). The professional standards invoked to justify problem-focused statements comprised the definition of an ideal behavior, attitude or ability and a tolerance range that was adapted in a dynamic process. Behavior falling outside the tolerance range was criticized as unacceptable, requiring action to prevent similar deviations in the future. Furthermore, we derived three strategies (minimization, homogenization and quality management) proposed by participants to manage deviations from assumed professional standards by FB&FT physicians. We critically reflect on the social processes of evaluation and problematization and question the legitimacy of professional standards invoked. We also discuss discriminatory tendencies visible in evaluative statements of some participants as well as in some of the strategies proposed. We suggest it will be key to develop and implement better support strategies for FB&FT physicians while also addressing problematic attitudes within the receiving system to further professional integration.

Work and the journey to recovery: exploring the implications of welfare reform for methadone maintenance clients.

PubMed

Monaghan, Mark; Wincup, Emma

2013-11-01

An emphasis on welfare reform has been a shared concern of recent UK governments, with the project of transforming the provision of welfare gathering pace over the past six years. Replicating active labour market policies pursued across the globe, successive governments have used welfare-to-work programmes as mechanisms to address worklessness. Since 2008, problem drug users (PDUs) have been added to a list of groups for whom intervention is deemed necessary to encourage, enable, and sometimes coerce them into paid employment. This approach is underpinned by three beliefs relating to paid work: it sustains recovery, has a transformative potential and should be the primary duty of the responsible citizen. Using policy developments in the UK as a case study, the article explores the implications for methadone maintenance clients of connecting drug policy (premised on the belief that work is central to recovery) with welfare policy (which at present is preoccupied with reducing worklessness). A critical analysis of policy documents, including drug strategies, Green and White papers and welfare reform legislation, alongside a review of relevant academic literature. The 'work first' approach which underpins current labour market activation policies in the UK and elsewhere is insufficiently flexible to accommodate the diverse needs of PDUs in recovery, and is particularly particular problematic when combined with a 'social deficit' model which concentrates on individual rather than structural barriers to employability. The use of payment-by-results mechanisms to provide employment services, coupled with the use of sanctions for those who do not engage, is likely to be particularly problematic for methadone maintenance clients. Welfare reform in the UK is likely to undermine the recovery of methadone maintenance clients. Further research is urgently needed to explore its impact on this sub-group of PDUs, alongside comparative studies to determine best practice in integrating drug and welfare policies.

Problematics of open prostatectomy in an Ivorian District Hospital setting.

Mgbakor, Anthony Chukwura

2012-09-01

Benign prostatic hypertrophy forms the bulk of urology workload in many sub-Saharan African hospitals. However, its management in secondary hospitals encounters specific problems that are rarely seen in the bigger tertiary institutions. We have tried to describe these difficulties across an account of open prostatectomy in regional secondary referral hospitals in the Côte d'Ivoire. This is a retrospective account of the specific difficulties encountered in the management of 327 consecutive cases of open prostatectomy carried out between August 1991 and September 2007 mainly in two secondary referral hospitals in the Côte d'Ivoire. The difficulties were at different levels: late presentation with 309 (94.5%) of the patients having experienced at least an episode of acute retention of urine, surgery while most patients were still carrying a catheter, minimal investigations carried out, scoring the patients in the IPSS scale, shortage of funds in the course of the management, and surveillance in the immediate postoperative period. The overall results were relatively satisfactory given our conditions of work. The most frequent complications were wound infection (14.7%), bleeding requiring transfusion (8.6%) and re-operation for clot retention (4.3%). We had a case (0.3%) of the rare prostato-rectal fistula which was managed conservatively. There were 4 deaths (1.2%). Open prostatectomy is the only surgical option for the management of benign prostatic hypertrophy in most of the urology centers of sub-Saharan Africa. Concerning its management away from the Tertiary Institutes, the surgery team is faced with specific problems which demand precise adaptations. Despite difficult working conditions, the results are sufficiently encouraging and gratifying to justify its pursuit while Urologists await the availability of equipments for transurethral resection of the prostate and other novel techniques.

Problematic video game play in a college sample and its relationship to time management skills and attention-deficit/hyperactivity disorder symptomology.

Tolchinsky, Anatol; Jefferson, Stephen D

2011-09-01

Although numerous benefits have been uncovered related to moderate video game play, research suggests that problematic video game playing behaviors can cause problems in the lives of some video game players. To further our understanding of this phenomenon, we investigated how problematic video game playing symptoms are related to an assortment of variables, including time management skills and attention-deficit/hyperactivity disorder (ADHD) symptoms. Additionally, we tested several simple mediation/moderation models to better explain previous theories that posit simple correlations between these variables. As expected, the results from the present study indicated that time management skills appeared to mediate the relationship between ADHD symptoms and problematic play endorsement (though only for men). Unexpectedly, we found that ADHD symptoms appeared to mediate the relation between time management skills and problematic play behaviors; however, this was only found for women in our sample. Finally, future implications are discussed.

Problematic Smartphone Use: Investigating Contemporary Experiences Using a Convergent Design

Internet-enabled smartphones are increasingly ubiquitous in the Western world. Research suggests a number of problems can result from mobile phone overuse, including dependence, dangerous and prohibited use. For over a decade, this has been measured by the Problematic Mobile Phone Use Questionnaire (PMPU-Q). Given the rapid developments in mobile technologies, changes of use patterns and possible problematic and addictive use, the aim of the present study was to investigate and validate an updated contemporary version of the PMPU-Q (PMPU-Q-R). A mixed methods convergent design was employed, including a psychometric survey (N = 512) alongside qualitative focus groups (N = 21), to elicit experiences and perceptions of problematic smartphone use. The results suggest the PMPU-Q-R factor structure can be updated to include smartphone dependence, dangerous driving, and antisocial smartphone use factors. Theories of problematic mobile phone use require consideration of the ubiquity and indispensability of smartphones in the present day and age, particularly regarding use whilst driving and in social interactions.

Background and aims Recent research on problematic Facebook use has highlighted the need to develop a specific theory-driven measure to assess this potential behavioral addiction. The aim of the present study was to examine the factorial validity of the Problematic Facebook Use Scale (PFUS) adapted from Caplan’s Generalized Problematic Internet Scale model. Methods A total of 1,460 Italian adolescents and young adults (aged 14–29 years) participated in the study. Confirmatory factor analyses were performed in order to assess the factorial validity of the scale. Results Results revealed that the factor structure of the PFUS provided a good fit to the data. Furthermore, results of the multiple group analyses supported the invariance of the model across age and gender groups. Discussion and conclusions This study provides evidence supporting the factorial validity of the PFUS. This new scale provides a theory-driven tool to assess problematic use of Facebook among male and female adolescents and young adults. PMID:28198639

The present study examined associations between stress and problematic alcohol use among US Navy members anticipating deployment, whether depressive symptoms mediated the stress-alcohol link, and whether social support and relationship satisfaction moderated associations between stress, depressive symptoms, and problematic alcohol use. Participants were 108 US Navy members assigned to an Arleigh Burke-class destroyer anticipating an 8-month deployment after Operational Enduring Freedom/Operation Iraqi Freedom. Stress was indirectly related to problematic alcohol use such that higher levels of stress were associated with higher levels of depressive symptoms, which were further associated with higher levels of alcohol use. The indirect effect of stress to problematic alcohol use via depressive symptoms was tested at different levels of social support and relationship satisfaction. At higher levels of social support and relationship satisfaction, the association between stress and problematic alcohol use via depressive symptoms decreased. Results help identify targets for alcohol prevention efforts among current military members.

Alcohol use and impulsivity are two known risk factors for intimate partner violence (IPV). The current study examined the independent and interactive effects of problematic drinking and five facets of impulsivity (i.e., negative urgency, positive urgency, sensation seeking, lack of premeditation, and lack of perseverance) on perpetration of physical IPV within a dyadic framework. Participants were 289 heavy drinking heterosexual couples (total N = 578) with a recent history of psychological and/or physical IPV recruited from two metropolitan U.S. cities. Parallel multilevel Actor Partner Interdependence Models were utilized and demonstrated Actor problematic drinking, negative urgency, and lack of perseverance were associated with physical IPV. Findings also revealed associations between Partner problematic drinking and physical IPV as well as significant Partner Problematic Drinking x Actor Impulsivity (Negative Urgency and Positive Urgency) interaction effects on physical IPV. Findings highlight the importance of examining IPV within a dyadic framework and are interpreted using the I3 meta-theoretical model. PMID:26828640

This study surveyed Dutch adolescents and adults about their video gaming behavior to assess the prevalence of problematic gaming. A representative national panel of 902 respondents aged 14 to 81 took part in the study. The results show that gaming in general is a wide-spread and popular activity among the Dutch population. Browser games (small games played via the internet) and offline casual games (e.g., offline card games) were reported as most popular type of game. Online games (e.g., massively multiplayer online role-playing games) are played by a relatively small part of the respondents, yet considerably more time is spent on these online games than on browser games, offline casual games, and offline games (e.g., offline racing games). The prevalence of problematic gaming in the total sample is 1.3 percent. Among adolescents and young adults problematic gaming occurs in 3.3 percent of cases. Particularly male adolescents seem to be more vulnerable to developing problematic gaming habits.

Problematic Internet use and physical health.

Background and aims A considerable body of literature has emerged over the past two decades assessing the relationship between problematic or addictive use of the Internet and various indices of psychological well-being. Conversely, comparatively little research has assessed the relationship between problematic or addictive use of the Internet and one's physical health. Method The current study assesses this relationship using a sample of college students (N = 133) who responded online to two questionnaires: the Problematic Internet Use Questionnaire (PIUQ; Demetrovics, Szeredi&Rózsa, 2008) and the SF-36v2 Health Survey (Ware et al., 2008). Results The findings indicate that problematic Internet use is associated with poorer physical health. These results are consistent with other data that assessed the relationship between these two variables. Furthermore, this relationship supersedes the influence of the number of hours spent online per day. Conclusions The findings are discussed in terms of the limitations of the study design and conclusions that can be drawn from this preliminary empirical effort.

Background and aims Tinder is a very popular smartphone-based geolocated dating application. The goal of the present study was creating a short Problematic Tinder Use Scale (PTUS). Methods Griffiths’ (2005) six-component model was implemented for covering all components of problematic Tinder use. Confirmatory factor analyses were carried out on a Tinder user sample (N = 430). Results Both the 12- and the 6-item versions were tested. The 6-item unidimensional structure has appropriate reliability and factor structure. No salient demography-related differences were found. Users irrespectively to their relationship status have similar scores on PTUS. Discussion Tinder users deserve the attention of scientific examination considering their large proportion among smartphone users. It is especially true considering the emerging trend of geolocated online dating applications. Conclusions Before PTUS, no prior scale has been created to measure problematic Tinder use. The PTUS is a suitable and reliable measure to assess problematic Tinder use. PMID:27415602

The Prevalence of Inappropriate Image Duplication in Biomedical Research Publications

Casadevall, Arturo; Fang, Ferric C.

2016-01-01

ABSTRACT Inaccurate data in scientific papers can result from honest error or intentional falsification. This study attempted to determine the percentage of published papers that contain inappropriate image duplication, a specific type of inaccurate data. The images from a total of 20,621 papers published in 40 scientific journals from 1995 to 2014 were visually screened. Overall, 3.8% of published papers contained problematic figures, with at least half exhibiting features suggestive of deliberate manipulation. The prevalence of papers with problematic images has risen markedly during the past decade. Additional papers written by authors of papers with problematic images had an increased likelihood of containing problematic images as well. As this analysis focused only on one type of data, it is likely that the actual prevalence of inaccurate data in the published literature is higher. The marked variation in the frequency of problematic images among journals suggests that journal practices, such as prepublication image screening, influence the quality of the scientific literature.

Lam, Lawrence T

2014-04-01

The effect of problematic use of the Internet on mental health, particularly depression among young people, has been established but without a probable model for the underlying mechanism. In this study, a model is presented to describe possible pathways for the linkage between Internet gaming addiction and depression possibly mediated by sleep problems. A systematic review was conducted to gather epidemiological evidence to support or refute the link between addictive Internet gaming, problematic Internet use, and sleep problems including insomnia and poor sleep quality. Seven studies were identified through a systematic literature search, of these three related to addictive Internet gaming and four on problematic Internet uses and sleep problems. Information was extracted and analysed systematically from each of the studies and tabulated as a summary. Results of the review suggest that additive gaming, particularly massively multiplayer online role-playing games MMORPG, might be associated with poorer quality of sleep. Results further indicated that problematic Internet use was associated with sleep problems including subjective insomnia and poor sleep quality.

Background and aims Recent research on problematic Facebook use has highlighted the need to develop a specific theory-driven measure to assess this potential behavioral addiction. The aim of the present study was to examine the factorial validity of the Problematic Facebook Use Scale (PFUS) adapted from Caplan's Generalized Problematic Internet Scale model. Methods A total of 1,460 Italian adolescents and young adults (aged 14-29 years) participated in the study. Confirmatory factor analyses were performed in order to assess the factorial validity of the scale. Results Results revealed that the factor structure of the PFUS provided a good fit to the data. Furthermore, results of the multiple group analyses supported the invariance of the model across age and gender groups. Discussion and conclusions This study provides evidence supporting the factorial validity of the PFUS. This new scale provides a theory-driven tool to assess problematic use of Facebook among male and female adolescents and young adults.

Grandiose and Vulnerable Narcissists: Who Is at Higher Risk for Social Networking Addiction?

PubMed

Casale, Silvia; Fioravanti, Giulia; Rugai, Laura

2016-08-01

Scholars have recently taken an interest in the connection between narcissism and Internet use, especially among users who frequent social networking sites (SNSs). Conversely, the association between narcissism and problematic use of SNSs (i.e., unregulated use that leads to negative outcomes) has been scarcely investigated. This study addresses this gap by comparing the mean levels of problematic use of SNSs among grandiose narcissists, vulnerable narcissists, and non-narcissists. A sample of 535 students completed the 16-item Narcissistic Personality Inventory, the Hypersensitive Narcissism Scale, and the Generalized Problematic Internet Use Scale-2 (GPIUS2). Vulnerable narcissists reported (a) significant higher levels on all GPIUS2 subscales and total scores than non-narcissists and (b) a stronger preference for online social interactions and higher overall levels of problematic use of SNSs than grandiose narcissists. Conversely, no significant differences were found between grandiose narcissists and non-narcissists. This study suggests that vulnerable narcissism may contribute more to problematic use of SNSs than grandiose narcissism.

Attributions of Stability, Control and Responsibility: How Parents of Children with Intellectual Disabilities View their Child's Problematic Behaviour and Its Causes.

2016-01-01

Children with intellectual disabilities have high rates of behaviour problems. This study explored parents' causal beliefs and attributions for general problematic child behaviour in children with different aetiologies of intellectual disabilities. Ten parents of children with intellectual disabilities participated in interviews about their child's problematic behaviour. Thematic analysis using NVivo revealed that parents viewed their child's problematic behaviour not only as caused by the child's intellectual disabilities but also by other causes unrelated to the intellectual disabilities, as well as by aspects of the social environmental context. Some causes were viewed as stable and uncontrollable and others as unstable and controllable. In addition, parents showed a strong sense of responsibility for child behaviour. Parents of children with intellectual disabilities do not solely interpret their child's problematic behaviour through the intellectual disabilities but incorporate the environment and causes and attributions that are not related to the intellectual disabilities, which may help to promote more effective parenting. © 2015 John Wiley & Sons Ltd.

2017-01-01

Background and aims Over the last decade, worldwide smartphone usage has greatly increased. Alongside this growth, research on the influence of smartphones on human behavior has also increased. However, a growing number of studies have shown that excessive use of smartphones can lead to detrimental consequences in a minority of individuals. This study examines the psychological aspects of smartphone use particularly in relation to problematic use, narcissism, anxiety, and personality factors. Methods A sample of 640 smartphone users ranging from 13 to 69 years of age (mean = 24.89 years, SD = 8.54) provided complete responses to an online survey including modified DSM-5 criteria of Internet Gaming Disorder to assess problematic smartphone use, the Spielberger State-Trait Anxiety Inventory, the Narcissistic Personality Inventory, and the Ten-Item Personality Inventory. Results The results demonstrated significant relationships between problematic smartphone use and anxiety, conscientiousness, openness, emotional stability, the amount of time spent on smartphones, and age. The results also demonstrated that conscientiousness, emotional stability, and age were independent predictors of problematic smartphone use. Conclusion The findings demonstrate that problematic smartphone use is associated with various personality factors and contributes to further understanding the psychology of smartphone behavior and associations with excessive use of smartphones.

In light of the increasing elderly population and the growing demand for home care, the potential of robot support is given increasing attention. In this paper, an inventory of activities was made that threaten independent living of elderly when becoming problematic. Results will guide the further development of an existing service robot, the Care-O-bot®. A systematic literature search of PubMed was performed, focused on the risk factors for institutionalization. Additionally, focus group sessions were conducted in the Netherlands, United Kingdom and France. In these focus group sessions, problematic activities threatening the independence of elderly people were discussed. Three separate target groups were included in the focus group sessions: (1) elderly persons (n = 41), (2) formal caregivers (n = 40) and (3) informal caregivers (n = 32). Activities within the International Classification of Functioning domains mobility, self-care, and interpersonal interaction and relationships were found to be the most problematic. A distinct set of daily activities was identified that may threaten independent living, but no single activity could be selected as the main activity causing a loss of independence as it is often a combination of problematic activities that is person-specific. Supporting the problematic activities need not involve a robotic solution.

Video game use and cognitive performance: does it vary with the presence of problematic video game use?

PubMed

Collins, Emily; Freeman, Jonathan

2014-03-01

Action video game players have been found to outperform nonplayers on a variety of cognitive tasks. However, several failures to replicate these video game player advantages have indicated that this relationship may not be straightforward. Moreover, despite the discovery that problematic video game players do not appear to demonstrate the same superior performance as nonproblematic video game players in relation to multiple object tracking paradigms, this has not been investigated for other tasks. Consequently, this study compared gamers and nongamers in task switching ability, visual short-term memory, mental rotation, enumeration, and flanker interference, as well as investigated the influence of self-reported problematic video game use. A total of 66 participants completed the experiment, 26 of whom played action video games, including 20 problematic players. The results revealed no significant effect of playing action video games, nor any influence of problematic video game play. This indicates that the previously reported cognitive advantages in video game players may be restricted to specific task features or samples. Furthermore, problematic video game play may not have a detrimental effect on cognitive performance, although this is difficult to ascertain considering the lack of video game player advantage. More research is therefore sorely needed.

We examined the association of body mass index (BMI), body weight perception, and weight control behaviors with problematic Internet use in a nationwide sample of Korean adolescents. Cross-sectional data from the 2010 Korean Youth Risk Behavior Web-based Survey collected from 37,041 boys and 33,655 girls in middle- and high- schools (grades 7-12) were analyzed. Participants were classified into groups based on BMI (underweight, normal weight, overweight, and obese), body weight perception (underweight, normal weight, and overweight), and weight control behavior (no weight control behavior, appropriate weight control behavior, inappropriate weight control behavior). The risk of problematic Internet use was assessed with the Korean Internet Addiction Proneness Scale for Youth-Short Form. Both boys and girls with inappropriate weight control behavior were more likely to have problematic Internet use. Underweight, overweight, and obese boys and girls were more likely to have problematic Internet use. For both boys and girls, subjective perception of underweight and overweight were positively associated with problematic Internet use. Given the negative effect of inappropriate weight control behavior, special attention needs to be given to adolescents' inappropriate weight control behavior, and an educational intervention for adolescents to control their weight in healthy ways is needed.

HIV infection is problematic among all drug users, not only injection drug users. Drug users are at risk for contracting HIV by engaging in risky sexual behaviors. The present study sought to determine whether inhibitory processes moderate the relationship between problematic drug use and HIV-risk behaviors (unprotected sex and multiple sex partners). One hundred ninety-six drug offenders enrolled in drug education programs were administered a battery of computer-based assessments. Measures included a cued go/no-go assessment of inhibitory processes, the Drug Abuse Screening Test (DAST) assessment of problematic drug use, and self-report assessment of condom use and multiple sex partners. Findings revealed that response inhibition assessed by the proportion of false alarms on the cued go/no-go moderated the relationship between problematic drug use and an important measure of HIV risk (condom nonuse) among drug offenders. However, response inhibition did not moderate the relationship between problematic drug use and another measure of HIV risk: multiple sex partners. Among this sample of drug offenders, we have found a relationship between problematic drug use and condom nonuse, which is exacerbated by poor control of inhibition. These findings have implications for the development of HIV intervention components among high-risk populations.

There is concern about the potential for negative impact of video games on youth. However the existing literature on gaming is inconsistent and has often focused on aggression. Health correlates of gaming and the prevalence and correlates of problematic gaming have not been systematically studied. We anonymously surveyed 4,028 adolescents about gaming, reported problems with gaming, and other health behaviors. 51.2% of the sample reported gaming (76.3% of boys and 29.2% of girls). There were no negative health correlates of gaming in boys, and lower odds of smoking regularly; however, girls who reported gaming were less likely to report depression, and more likely to report getting into serious fights and carrying a weapon to school. Among gamers, 4.9% reported problematic gaming, defined as reporting trying to cut back, experiencing an irresistible urge to play, and experiencing a growing tension that could only be relieved by playing. Boys were more likely to report these problems (5.8%) than girls (3.0%). Correlates of problematic gaming included regular cigarette smoking, drug use, depression, and serious fights. Results suggest that gaming is largely normative in boys and not associated with many health factors. In girls, however, gaming appears associated with more externalizing behaviors and fewer internalizing symptoms. The prevalence of problematic gaming is low but not insignificant, and problematic gaming may be contained within a larger spectrum of externalizing behaviors. More research is needed to define safe levels of gaming, refine the definition of problematic gaming, and evaluate effective prevention and intervention strategies. PMID:21078729

Background and objectives The ubiquitous Internet connections by smartphones weakened the traditional boundaries between computers and mobile phones. We sought to explore whether smartphone-related problems differ from those of computer use according to gender using latent class analysis (LCA). Methods After informed consents, 555 Korean middle-school students completed surveys on gaming, Internet use, and smartphone usage patterns. They also completed various psychosocial instruments. LCA was performed for the whole group and by gender. In addition to ANOVA and χ 2 tests, post-hoc tests were conducted to examine differences among the LCA subgroups. Results In the whole group (n = 555), four subtypes were identified: dual-problem users (49.5%), problematic Internet users (7.7%), problematic smartphone users (32.1%), and "healthy" users (10.6%). Dual-problem users scored highest for addictive behaviors and other psychopathologies. The gender-stratified LCA revealed three subtypes for each gender. With dual-problem and healthy subgroup as common, problematic Internet subgroup was classified in the males, whereas problematic smartphone subgroup was classified in the females in the gender-stratified LCA. Thus, distinct patterns were observed according to gender with higher proportion of dual-problem present in males. While gaming was associated with problematic Internet use in males, aggression and impulsivity demonstrated associations with problematic smartphone use in females. Conclusions An increase in the number of digital media-related problems was associated with worse outcomes in various psychosocial scales. Gaming may play a crucial role in males solely displaying Internet-related problems. The heightened impulsivity and aggression seen in our female problematic smartphone users requires further research.

Problematic anger is a significant clinical issue in military personnel, and is further complicated by comorbid post-traumatic stress disorder (PTSD). Despite increasing numbers of military personnel returning from deployment with anger and aggression difficulties, the treatment of problematic anger has received scant attention. There are currently no interventions that directly target problematic anger in the context of military-related PTSD. The aim of this case series is to examine the effectiveness of an intervention specifically developed for treating problematic anger in current serving military personnel with comorbid PTSD. Eight Australian Defence Force Army personnel with problematic anger and comorbid PTSD received a manualized 12-session cognitive behaviorally based anger intervention, delivered one-to-one by Australian Defence Force mental health clinicians. Standardized measures of anger, PTSD, depression, and anxiety were administered pre- and post-treatment. The initial mean severity scores for anger indicated a high degree of pre-treatment problematic anger. Anger scores reduced significantly from pre to post-treatment (d = 1.56), with 88% of participants exhibiting meaningful reduction in anger scores. PTSD symptoms also reduced significantly (d= 0.96), with 63% of participants experiencing a clinically meaningful reduction in PTSD scores. All of those who took part in the therapy completed all therapy sessions. This brief report provides preliminary evidence that an intervention for problematic anger not only significantly reduces anger levels in military personnel, but can also significantly reduce PTSD symptoms. Given that anger can interfere with PTSD treatment outcomes, prioritizing anger treatment may improve the effectiveness of PTSD interventions.

The emerging field of Information and Communications Technology (ICT) has brought about new interaction styles. Its excessive use may lead to addictive behaviours. The objective is to determine the prevalence of the problematic use of ICT such as Internet, mobile phones and video games, among adolescents enrolled in mandatory Secondary Education (ESO in Spanish) and to examine associated factors. Cross sectional, multi-centric descriptive study. 5538 students enrolled in years one to four of ESO at 28 schools in the Vallès Occidental region (Barcelona, Spain). self-administered socio-demographic and ICT access questionnaire, and validated questionnaires on experiences related to the use of the Internet, mobile phones and video games (CERI, CERM, CERV). Questionnaires were collected from 5,538 adolescents between the ages of 12 and 20 (77.3 % of the total response), 48.6 % were females. Problematic use of the Internet was observed in 13.6 % of the surveyed individuals; problematic use of mobile phones in 2.4 % and problematic use in video games in 6.2 %. Problematic Internet use was associated with female students, tobacco consumption, a background of binge drinking, the use of cannabis or other drugs, poor academic performance, poor family relationships and an intensive use of the computer. Factors associated with the problematic use of mobile phones were the consumption of other drugs and an intensive use of these devices. Frequent problems with video game use have been associated with male students, the consumption of other drugs, poor academic performance, poor family relationships and an intensive use of these games. This study offers information on the prevalence of addictive behaviours of the Internet, mobile phones and video game use. The problematic use of these ICT devices has been related to the consumption of drugs, poor academic performance and poor family relationships. This intensive use may constitute a risk marker for ICT addiction.

Soot Formation in Freely-Propagating Laminar Premixed Flames

Soot formation within hydrocarbon-fueled flames is an important unresolved problem of combustion science. Thus, the present study is considering soot formation in freely-propagating laminar premixed flames, exploiting the microgravity environment to simplify measurements at the high-pressure conditions of interest for many practical applications. The findings of the investigation are relevant to reducing emissions of soot and continuum radiation from combustion processes, to improving terrestrial and spacecraft fire safety, and to developing methods of computational combustion, among others. Laminar premixed flames are attractive for studying soot formation because they are simple one-dimensional flows that are computationally tractable for detailed numerical simulations. Nevertheless, studying soot-containing burner-stabilized laminar premixed flames is problematical: spatial resolution and residence times are limited at the pressures of interest for practical applications, flame structure is sensitive to minor burner construction details so that experimental reproducibility is not very good, consistent burner behavior over the lengthy test programs needed to measure soot formation properties is hard to achieve, and burners have poor durability. Fortunately, many of these problems are mitigated for soot-containing, freely-propagating laminar premixed flames. The present investigation seeks to extend work in this laboratory for various soot processes in flames by observing soot formation in freely-propagating laminar premixed flames. Measurements are being made at both Normal Gravity (NG) and MicroGravity (MG), using a short-drop free-fall facility to provide MG conditions.

Ethnic minority families in Europe are underrepresented in mental health care-a profound problem for clinicians and policymakers. One reason for their underrepresentation seems that, on average, ethnic minority families tend to perceive externalizing and internalizing child behavior as less problematic. There is concern that this difference in problem perception might limit intervention effectiveness. We tested the extent to which ethnic differences in problem perception exist when ethnic minority families engage in mental health service and whether lower levels of problem perception diminish parenting intervention effects to reduce disruptive child behavior. Our sample included 136 mothers of 3- to 8-year-olds (35% female) from the 3 largest ethnic groups in the Netherlands (43% Dutch; 35% Moroccan; 22% Turkish). Mothers reported on their child's externalizing and internalizing behavior and their perception of this behavior as problematic. They were then randomly assigned to the Incredible Years parenting intervention or a wait list control condition. We contrasted maternal reports of problem perception to teacher reports of the same children. Moroccan and Turkish mothers, compared with Dutch mothers, perceived similar levels of child behavior problems as less problematic, and as causing less impairment and burden. Teacher problem perception did not vary across children from different ethnic groups. Importantly, maternal problem perception did not affect parenting intervention effectiveness to reduce disruptive child behavior. Our findings suggest that ethnic differences in problem perception exist once families engage in treatment, but that lower levels of problem perception do not diminish treatment effects.

Should executive control, as indicated by working memory capacity (WMC) and mind-wandering propensity, help or hinder creativity? Sustained and focused attention should help guide a selective search of solution-relevant information in memory and help inhibit uncreative, yet accessible, ideas. However, unfocused attention and daydreaming should allow mental access to more loosely relevant concepts, remotely linked to commonplace solutions. Three individual-differences studies inserted incubation periods into one or two divergent thinking tasks and tested whether WMC (assessed by complex span tasks) and incubation-period mind wandering (assessed as probed reports of task-unrelated thought [TUT]) predicted post-incubation performance. Retrospective self-reports of Openness (Experiment 2) and mind-wandering and daydreaming propensity (Experiment 3) complemented our thought-probe assessments of TUT. WMC did not correlate with creativity in divergent thinking, whereas only the questionnaire measure of daydreaming, but not probed thought reports, weakly predicted creativity; the fact that in-the-moment TUTs did not correlate divergent creativity is especially problematic for claims that mind-wandering processes contribute to creative cognition. Moreover, the fact that WMC tends to strongly predict analytical problem solving and reasoning, but may not correlate with divergent thinking, provides a useful boundary condition for defining WMC's nomological net. On balance, our data provide no support for either benefits or costs of executive control for at least one component of creativity.

How can we estimate natural selection on endocrine traits? Lessons from evolutionary biology

An evolutionary perspective can enrich almost any endeavour in biology, providing a deeper understanding of the variation we see in nature. To this end, evolutionary endocrinologists seek to describe the fitness consequences of variation in endocrine traits. Much of the recent work in our field, however, follows a flawed approach to the study of how selection shapes endocrine traits. Briefly, this approach relies on among-individual correlations between endocrine phenotypes (often circulating hormone levels) and fitness metrics to estimate selection on those endocrine traits. Adaptive plasticity in both endocrine and fitness-related traits can drive these correlations, generating patterns that do not accurately reflect natural selection. We illustrate why this approach to studying selection on endocrine traits is problematic, referring to work from evolutionary biologists who, decades ago, described this problem as it relates to a variety of other plastic traits. We extend these arguments to evolutionary endocrinology, where the likelihood that this flaw generates bias in estimates of selection is unusually high due to the exceptional responsiveness of hormones to environmental conditions, and their function to induce adaptive life-history responses to environmental variation. We end with a review of productive approaches for investigating the fitness consequences of variation in endocrine traits that we expect will generate exciting advances in our understanding of endocrine system evolution.

Coordinated movements between the eyes and head are required to maintain a stable retinal image during head and body motion. The vestibulo-ocular reflex (VOR) plays a significant role in this gaze control system that functions well for most daily activities. However, certain environmental conditions or interruptions in normal VOR function can lead to inadequate ocular compensation, resulting in oscillopsia, or blurred vision. It is therefore possible to use acuity to determine when the environmental conditions, VOR function, or the combination of the two is not conductive for maintaining clear vision. Over several years we have designed and tested several tests of dynamic visual acuity (DVA). Early tests used the difference between standing and walking acuity to assess decrements in the gaze stabilization system after spaceflight. Supporting ground-based studies measured the responses from patients with bilateral vestibular dysfunction and explored the effects of visual target viewing distance and gait cycle events on walking acuity. Results from these studies show that DVA is affected by spaceflight, is degraded in patients with vestibular dysfunction, changes with target distance, and is not consistent across the gait cycle. We have recently expanded our research to include studies in which seated subjects are translated or rotated passively. Preliminary results from this work indicate that gaze stabilization ability may differ between similar active and passive conditions, may change with age, and can be affected by the location of the visual target with respect to the axis of motion. Use of DVA as a diagnostic tool is becoming more popular but the functional nature of the acuity outcome measure also makes it ideal for identifying conditions that could lead to degraded vision. By doing so, steps can be taken to alter the problematic environments to improve the man-machine interface and optimize performance.

Applications of a hand-held GPS receiver in South American rain forests

A hand-held Global Positioning System receiver was used to determine the precise locations of villages, houses, gardens, and other cultural and environmental features in poorly mapped South American rain forests. The Magellan NAV 1000 unit profides extremely accurate latitude and longitude information, but determination of altitude is problematical. Overall, the receiver effectively allows anthropologists to obtain essential locational data useful for categorizing land uses, mapping tribal boundaries, and other applications in regions where environmental conditions are harsh and/or accessibility is difficult.
