The aim of the present study was to investigate relationships between sense of coherence, emotion-focused coping, problem-focused coping, coping efficiency, and mental quality of life (QoL) in patients with chronic illness. A model based on Lazarus' and Folkman's stress and coping theory tested the specific hypothesis: Sense of coherence has a direct and indirect effect on mental QoL mediated by emotion-focused coping, problem-focused coping, and coping efficiency in serial adjusted for age, gender, educational level, comorbidity, and economic status. The study used a cross-sectional and correlational design. Patients (n = 292) with chronic diseases (chronic heart failure, end-stage renal disease, multiple sclerosis, stroke, and Parkinson) completed three questionnaires and provided background data. Data were collected in 2012, and a serial multiple mediator model was tested using PROCESS macro for SPSS. The test of the conceptual model confirmed the hypothesis. There was a significant direct and indirect effect of sense of coherence on mental QoL through the three mediators. The model explained 39% of the variance in mental QoL. Self-perceived effective coping strategies are the most important mediating factors between sense of coherence and QoL in patients with chronic illness, which supports Lazarus' and Folkman's stress and coping theory.

Studies have shown associations between health indices and access to "green" environments but the underlying mechanisms of this association are not clear. To examine associations of perceived neighbourhood "greenness" with perceived physical and mental health and to investigate whether walking and social factors account for the relationships. A mailed survey collected the following data from adults (n = 1895) in Adelaide, Australia: physical and mental health scores (12-item short-form health survey); perceived neighbourhood greenness; walking for recreation and for transport; social coherence; local social interaction and sociodemographic variables. After adjusting for sociodemographic variables, those who perceived their neighbourhood as highly green had 1.37 and 1.60 times higher odds of better physical and mental health, respectively, compared with those who perceived the lowest greenness. Perceived greenness was also correlated with recreational walking and social factors. When walking for recreation and social factors were added to the regression models, recreational walking was a significant predictor of physical health; however, the association between greenness and physical health became non-significant. Recreational walking and social coherence were associated with mental health and the relationship between greenness and mental health remained significant. Perceived neighbourhood greenness was more strongly associated with mental health than it was with physical health. Recreational walking seemed to explain the link between greenness and physical health, whereas the relationship between greenness and mental health was only partly accounted for by recreational walking and social coherence. The restorative effects of natural environments may be involved in the residual association of this latter relationship.

The neural correlates of exploration and cognitive mapping in blindness remain elusive. The role of visuo-spatial pathways in blind vs. sighted subjects is still under debate. In this preliminary study, we investigate, as a possible estimation of the activity in the visuo-spatial pathways, the EEG patterns of blind and blindfolded-sighted subjects during the active tactile construction of cognitive maps from virtual objects compared with rest and passive tactile stimulation. Ten blind and ten matched, blindfolded-sighted subjects participated in the study. Events were defined as moments when the finger was only stimulated (passive stimulation) or the contour of a virtual object was touched (during active exploration). Event-related spectral power and coherence perturbations were evaluated within the beta 1 band (14–18 Hz). They were then related to a subjective cognitive-load estimation required by the explorations [namely, perceived levels of difficulty (PLD)]. We found complementary cues for sensory substitution and spatial processing in both groups: both blind and sighted subjects showed, while exploring, late power decreases and early power increases, potentially associated with motor programming and touch, respectively. The latter involved occipital areas only for blind subjects (long-term plasticity) and only during active exploration, thus supporting tactile-to-visual sensory substitution. In both groups, coherences emerged among the fronto-central, centro-parietal, and occipito-temporal derivations associated with visuo-spatial processing. This seems in accordance with mental map construction involving spatial processing, sensory-motor processing, and working memory. The observed involvement of the occipital regions suggests that a substitution process also occurs in sighted subjects. Only during explorations did coherence correlate positively with PLD for both groups and in derivations, which can be related to visuo-spatial processing, supporting the existence of supramodal spatial processing independently of vision capabilities.

Psychiatric epidemiology, or the story of a divided discipline.

PubMed

Demazeux, Steeves

2014-08-01

This article traces the historical decisions, concepts and key professional collaborations that laid the foundations for the formation of American psychiatric epidemiology during the 20th century, up to the discipline's institutional consolidation, circa 1980, when the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III) was published. Thomas Kuhn's 'disciplinary matrix' is mobilized as a framework that allows the institutional and intellectual construction of a discipline to be analysed as separate but intertwined components, without assuming that the two evolve in tandem. The identification of the strengths as well as the frailties and internal divisions of the discipline as it developed reveals a paradoxical situation: a time lag between psychiatric epidemiology's institutionalization and public recognition, on the one hand; and the weak coherence of its intellectual components, on the other hand. We briefly trace the origins of split among the discipline's aetiological models of mental disorders and suggest that the lack of coherence among them has prevented psychiatric epidemiology from achieving the status of a normal scientific discipline, in the Kuhnian sense. Without a more explicit attention to the intellectual rationale of the discipline, psychiatric epidemiology will continue to maintain a strong institutional dimension and weak intellectual matrix. © The Author 2014; all rights reserved.

Different concepts have been presented which denote driving forces and strengths that contribute to a person's ability to meet and handle adversities, and keep or regain health. The aim of this study, which is a part of The Umeå 85+ study, was to describe resilience, sense of coherence, purpose in life and self-transcendence in relation to perceived physical and mental health in a sample of the oldest old. The study sample consisted of 125 participants 85 years of age or older, who ranked themselves on the Resilience Scale, Sense of Coherence Scale, Purpose in Life Scale and Self-Transcendence Scale and answered the SF-36 Health Survey questionnaire. The findings showed significant correlations between scores on the Resilience Scale, the Sense of Coherence Scale, the Purpose in Life Test, and the Self-Transcendence Scale. Significant correlations were also found between these scales and the SF-36 Mental Health Summary among women but not among men. There was no significant correlation between perceived physical and mental health. The mean values of the different scales showed that the oldest old have the same or higher scores than younger age groups. Regression analyses also revealed sex differences regarding mental health. The conclusions are that, the correlation between scores on the different scales suggests that the scales measure some dimension of inner strength and that the oldest old have this strength at least in the same extent as younger adults. Another conclusion is that the dimensions that constitute mental health differ between women and men.

We explore the relationship between the 'theory of mind' (ToM) and 'central coherence' difficulties of autism. We introduce covariation between hierarchically-embedded categories and social information--at the local level, the global level, or at both levels simultaneously--within a category confusion task. We then ask participants to infer the mental state of novel category members, and measure participants' autism-spectrum quotient (AQ). Results reveal a positive relationship between AQ and the degree of local/global social categorization, which in turn predicts the pattern of mental state inferences. These results provide preliminary evidence for a causal relationship between central coherence and ToM abilities. Implications with regard to ToM processes, social categorization, intervention, and the development of a unified account of autism are discussed.

Physiological coherence has been related with a general sense of well-being and improvements in health and physical, social, and cognitive performance. The aim of this study was to evaluate the relationship between acute stress, controlled breathing, and physiological coherence, and the degree of body systems synchronization during a coherence-generation exercise. Thirty-four university employees were evaluated during a 20-min test consisting of four stages of 5-min duration each, during which basal measurements were obtained (Stage 1), acute stress was induced using validated mental stressors (Stroop test and mental arithmetic task, during Stage 2 and 3, respectively), and coherence states were generated using a controlled breathing technique (Stage 4). Physiological coherence and cardiorespiratory synchronization were assessed during each stage from heart rate variability, pulse transit time, and respiration. Coherence measurements derived from the three analyzed variables increased during controlled respiration. Moreover, signals synchronized during the controlled breathing stage, implying a cardiorespiratory synchronization was achieved by most participants. Hence, physiological coherence and cardiopulmonary synchronization, which could lead to improvements in health and better life quality, can be achieved using slow, controlled breathing exercises. Meanwhile, coherence measured during basal state and stressful situations did not show relevant differences using heart rate variability and pulse transit time. More studies are needed to evaluate the ability of coherence ratio to reflect acute stress. © 2017 Society for Psychophysiological Research.

This study explored spatial navigation alongside several other cognitive abilities that are thought to share common underlying neurocognitive mechanisms (e.g., the capacity for self-projection, scene construction, or mental simulation), and which we hypothesized may be impaired in autism spectrum disorder (ASD). Twenty intellectually high-functioning children with ASD (with a mean age of ~8 years) were compared to 20 sex, age, IQ, and language ability matched typically developing children on a series of tasks to assess spatial navigation, episodic memory, episodic future thinking (also known as episodic foresight or prospection), theory of mind (ToM), relational memory, and central coherence. This is the first study to explore these abilities concurrently within the same sample. Spatial navigation was assessed using the “memory island” task, which involves finding objects within a realistic, computer simulated, three-dimensional environment. Episodic memory and episodic future thinking were assessed using a past and future event description task. ToM was assessed using the “animations” task, in which children were asked to describe the interactions between two animated triangles. Relational memory was assessed using a recognition task involving memory for items (line drawings), patterned backgrounds, or combinations of items and backgrounds. Central coherence was assessed by exploring differences in performance across segmented and unsegmented versions of block design. Children with ASD were found to show impairments in spatial navigation, episodic memory, episodic future thinking, and central coherence, but not ToM or relational memory. Among children with ASD, spatial navigation was found to be significantly negatively related to the number of repetitive behaviors. In other words, children who showed more repetitive behaviors showed poorer spatial navigation. The theoretical and practical implications of the results are discussed. PMID:25538661

This study examined the effects of risk and protective factors on resilience in 60 women family members of adults with serious mental illness. Both the risk factors constituting caregiver burden (strain, stigma, client dependence, and family disruption) and protective factors, including eight positive cognitions were found to predict two indicators of resilience: resourcefulness and sense of coherence. The effects of caregiver burden on resourcefulness and sense of coherence were mediated by positive cognitions, lending support to resilience theory and suggesting the need to develop interventions to encourage positive thinking among women caregivers of adults with mental illness.

The aim of this study is to qualify the network properties of the brain networks between two different mental tasks (play task or rest task) in a healthy population. EEG signals were recorded from 19 healthy subjects when performing different mental tasks. Partial directed coherence (PDC) analysis, based on Granger causality (GC), was used to assess the effective brain networks during the different mental tasks. Moreover, the network measures, including degree, degree distribution, local and global efficiency in delta, theta, alpha, and beta rhythms were calculated and analyzed. The local efficiency is higher in the beta frequency and lower in the theta frequency during play task whereas the global efficiency is higher in the theta frequency and lower in the beta frequency in the rest task. This study reveals the network measures during different mental states and efficiency measures may be used as characteristic quantities for improvement in attentional performance.

Emergency mental health nursing for self-harming refugees and asylum seekers.

PubMed

Procter, Nicholas G

2005-09-01

This article describes the structure and function of emergency mental health nursing practice for self-harming refugees and asylum seekers on Temporary Protection Visas. Emergency nurses working in accident and emergency departments or as part of crisis intervention teams will see self-harming refugees and asylum seekers at the very point of their distress. This clinical paper is intended to support nurses in their practice should they encounter an adult asylum seeker needing emergency mental health care. Practical strategies are highlighted to help mental health nurses assess, care, and comfort refugees and asylum seekers in this predicament. Mental health nurses should, where possible, work closely with asylum seekers, their support workers, and accredited interpreters and translators to ensure the appropriate use of language when dealing with mental and emotional health issues without further isolating the asylum seeker from appropriate services. To help strengthen continuity and integration of mental health supports for refugees and asylum seekers, well-resourced care must be experienced as coherent and connected. A coherent, interdisciplinary and team-orientated approach will synthesize different viewpoints to shape clinical practice and create workable solutions in local situations.

Living into the story: agency and coherence in a longitudinal study of narrative identity development and mental health over the course of psychotherapy.

Adler, Jonathan M

2012-02-01

Narrative identity is the internalized, evolving story of the self that each person crafts to provide his or her life with a sense of purpose and unity. A proliferation of empirical research studies focused on narrative identity have explored its relationship with psychological well-being. The present study is the first prospective, multiwave longitudinal investigation to examine short-term personality change via an emphasis on narrative identity as it relates to mental health. Forty-seven adults wrote rich personal narratives prior to beginning psychotherapy and after every session over 12 assessment points while concurrently completing a measure of mental health. Narratives were coded for the themes of agency and coherence, which capture the dual aims of narrative identity: purpose and unity. By applying in-depth thematic coding to the stories of participants, the present study produced 47 case studies of intraindividual personality development and mental health. By employing multilevel modeling with the entire set of nearly 600 narratives, the present study also identified robust trends of individual differences in narrative changes as they related to improvements in mental health. Results indicated that, across participants, the theme of agency, but not coherence, increased over the course of time. In addition, increases in agency were related to improvements in participants' mental health. Finally, lagged growth curve models revealed that changes in the theme of agency occurred prior to the associated improvements in mental health. This finding remained consistent across a variety of individual-difference variables including demographics, personality traits, and ego development.

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

2010-09-01

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

Maternal mental health during pregnancy has been identified as a key factor in the future physiological, emotional and social development of both the mother and her baby. Yet little is known about the factors that contribute to increased levels of pregnancy-specific distress. The present study investigated the role of two psychosocial and personality-based constructs, namely women's sense of coherence (SoC) and their mothering orientations, on their pregnancy-specific distress. During their second trimester of pregnancy, 293 Australian and New Zealand women participated in an online study. Hierarchical multiple regression analysis was used to determine the unique contribution of women's SoC (Sense of Coherence Scale, SoC 13) and their antenatal mothering orientation (Antenatal Mothering Orientation Measure-Revised, AMOM-R) to pregnancy-specific distress (Revised Prenatal Distress Questionnaire, NuPDQ). Low SoC was the best determinant of women's pregnancy-specific distress, accounting for over 45% of the variance (β = -0.33, p < 0.001, 95% CI [-0.43, -0.23]). A Regulator mothering orientation was correlated with distress but did not have a unique contribution in the final model. This study further highlights the importance of better understanding women's perceptions of emotional health and their mothering role while taking into consideration their wider social context.

Relations Between Narrative Coherence, Identity, and Psychological Well-being in Emerging Adulthood

Objective The hypothesis that the ability to construct a coherent account of personal experience is reflective, or predictive, of psychological adjustment cuts across numerous domains of psychological science. It has been argued that coherent accounts of identity are especially adaptive. We tested these hypotheses by examining relations between narrative coherence of personally significant autobiographical memories and three psychological well-being components (Purpose and Meaning; Positive Self View; Positive Relationships). We also examined the potential moderation of the relations between coherence and well-being by assessing the identity content of each narrative. Method We collected two autobiographical narratives of personally significant events from 103 undergraduate students and coded them for coherence and identity content. Two additional narratives about generic/recurring events were also collected and coded for coherence. Results We confirmed the prediction that constructing coherent autobiographical narratives is related to psychological well-being. Further, we found that this relation was moderated by the narratives’ relevance to identity and that this moderation held after controlling for narrative ability more generally (i.e. coherence of generic/recurring events). Conclusion These data lend strong support to the coherent narrative identity hypothesis and the prediction that unique events are a critical feature of identity construction in emerging adulthood.

Although sense of coherence (SOC) moderates parental stress, the relationship between SOC, parental mental health and physical punishment of children with intellectual disabilities remains uncertain. The present authors describe parental physical punishment towards children with intellectual disabilities and investigate its related demographic characteristics, SOC and parental mental health. With the cooperation of Tokyo's 10 special needs schools, the present authors obtained 648 questionnaire responses from parents of children with intellectual disabilities. Of the parents, 69.7% reported having physically punished their children with intellectual disabilities. This was positively associated with parents' younger age, poorer mental health, lower SOC, children's younger age, birth order (firstborns) and disability type (autism/pervasive developmental disorder). This is the first study supporting the relationship between SOC, mental health and physical punishment use among parents of children with intellectual disabilities. It may assist the development of strategies to prevent physical abuse of children with disabilities. © 2015 John Wiley & Sons Ltd.

In this paper, we demonstrate dynamic analysis of mental sweating for sound stimulus of a few tens of eccrine sweat glands by the time-sequential piled-up en face optical coherence tomography (OCT) images with the frame spacing of 3.3 sec. In the experiment, the amount of excess sweat can be evaluated simultaneously for a few tens of sweat glands by piling up of all the en face OCT images. Non-uniformity was observed in mental sweating where the amount of sweat in response to sound stimulus is different for each sweat gland. Furthermore, the amount of sweat is significantly increased in proportion to the strength of the stimulus.

Scene construction in schizophrenia.

Recent research has revealed that schizophrenia patients are impaired in remembering the past and imagining the future. In this study, we examined patients' ability to engage in scene construction (i.e., the process of mentally generating and maintaining a complex and coherent scene), which is a key part of retrieving past experiences and episodic future thinking. 24 participants with schizophrenia and 25 healthy controls were asked to imagine new fictitious experiences and described their mental representations of the scenes in as much detail as possible. Descriptions were scored according to various dimensions (e.g., sensory details, spatial reference), and participants also provided ratings of their subjective experience when imagining the scenes (e.g., their sense of presence, the perceived similarity of imagined events to past experiences). Imagined scenes contained less phenomenological details (d = 1.11) and were more fragmented (d = 2.81) in schizophrenia patients compared to controls. Furthermore, positive symptoms were positively correlated to the sense of presence (r = .43) and the perceived similarity of imagined events to past episodes (r = .47), whereas negative symptoms were negatively related to the overall richness of the imagined scenes (r = -.43). The results suggest that schizophrenic patients' impairments in remembering the past and imagining the future are, at least in part, due to deficits in the process of scene construction. The relationships between the characteristics of imagined scenes and positive and negative symptoms could be related to reality monitoring deficits and difficulties in strategic retrieval processes, respectively.

Rotor coherent state constructions are given for the Wigner supermultiplet SU(4) contains SU(2)xSU(2) and for the special irreducible representations (N0) of the SO(5) contains SO(3) contains SO(2) group chain in exact parallel with the rotor coherent state construction for the SU(3) contains SO(3) contains SO(2) case given by Rowe, LeBlanc,, and Repka. Matrix elements of the coherent state realizations of the group generators are given in all cases by very simple expressions in terms of angular momentum Wigner coefficients involving intrinsic projection labels K. The K-matrix technique of vector coherent state theory is used to effectively elevate these K labels to the status of good quantum numbers. Analytic expressions are given for the (K K*)-matrices for many of the more important irreducible representations.

Narrative competence in Spanish-speaking adults with Williams syndrome.

2016-08-01

Williams syndrome (WS) is a genetic disorder associated with intellectual disability and characterised by displaying an atypical neuropsychological profile, with peaks and valleys, where language skills seem better preserved than non-verbal intelligence. This study researches the narrative competence of nine Spanish-speaking adults with WS. Oral narratives were elicited from a silent film, and narrative coherence was analysed as a function of sequential order of the events narrated at three structure levels, while narrative cohesion was assessed through the frequency of use and type of discourse markers. WS subjects were able to remember a significant proportion of the events from the film, but coherence of narratives, i.e., sequential order of events, was more impaired. Consistently with their linguistic abilities, cohesion of narratives was better preserved, as they used discourse markers to introduce a high proportion of events. Construction of mental models of the narratives may be constrained in WS by non-verbal cognitive abilities, but narrative competence is also determined by textual pragmatic abilities to organize discourse, which should be addressed by specific intervention in narrative competence.

Life expectancy is increasing in Latin America resulting in the need for more family caregivers for older adults with dementia. The purpose of the current study was to examine the relationships between personal strengths (optimism, sense of coherence [SOC], and resilience) and the mental health of dementia caregivers from Latin America. Primary family dementia caregivers (n = 127) were identified via convenience sampling at the Instituto de Neurociencias de San Lucas, Argentina, and CETYS University, in Baja California, Mexico and completed measures of these constructs. Personal strengths explained between 32% and 50% of the variance in caregiver mental health. In a series of hierarchical multiple regressions, more manageability (β = -.38, p = .001), general resilience (β = -.24, p = .012), and social competence (β = -.21, p = .034) were uniquely associated with lower depression. Greater comprehensibility (β = -.28, p = .008) was uniquely associated with decreased burden, and manageability was marginally related (β = -.21, p< .10). Greater optimism (β = .37, p< .001) and manageability (β = .27, p = .004) were uniquely associated with increased life satisfaction. The personal strengths of caregivers in Latin America may be particularly important for their mental health because of the culturally imbedded sense of duty toward older family members. Incorporating strengths-based approaches into research on caregiver interventions in regions where caregiving is a highly culturally valued role such as Latin America may have the potential to improve the mental health of dementia caregivers. © The Author(s) 2015.

2013-01-01

The purpose of this study was to examine the mental health effects of Tai chi on regular practitioners by investigating the relationships between flow experience, IKIGAI (Japanese: "Life worth living"), and sense of coherence. The results indicated that flow experience may influence IKIGAI and IKIGAI may influence sense of coherence; this suggests that IKIGAI may act as an intermediary between flow experience and sense of coherence. The results also indicated that the longer the Tai chi experience, the higher was the flow experience.

Few studies have examined the association between social support and health-related quality of life (HRQOL) among nursing home residents and whether the sense of coherence (SOC) modifies the effect of social support on health-related quality of life. The main aims of this study were to determine the relationship between social support and HRQOL and to investigate whether the SOC modifies the effect of social support on HRQOL. A cross-sectional, descriptive, correlational design. All 30 nursing homes in Bergen in western Norway. Two hundred and twenty-seven mentally intact long-term nursing home residents 65 years and older. Data were obtained through face-to-face interviews using the SF-36 Health Survey, Social Provisions Scale and Sense of Coherence Scale. Possible relationships between the Social Provisions Scale and the eight SF-36 subdimensions were analysed using multiple linear regression while controlling for age, sex, marital status, education and comorbid illness. Interactions between the Sense of Coherence Scale and Social Provisions Scale were investigated. Attachment affected the mental health subdimension (p=0.001), opportunity for nurturance affected social functioning (p=0.003) and reassurance of worth affected vitality (p=0.001) after adjustment for demographic variables and comorbid illness. After the analysis included the sense of coherence, nurturance still significantly affected social functioning and reassurance of worth still significantly affected vitality. No interaction with sense of coherence was found, and sense of coherence significantly affected all SF-36 subdimensions. The opportunity to provide nurturance for others appears to be important for social functioning, and sense of competence and sense of self-esteem appear to be important for vitality. Further, the residents' relationships with significant others comprise an important component of mental health. Finally, independent of the level of sense of coherence, social support is an important resource for better health-related quality of life. Clinical nurses should recognize that social support is associated with health-related quality of life and pay attention to the importance of social support for the residents in daily practice.

Anterior alpha asymmetry of electroencephalographic (EEG) signals has been suggested to index state approach (or avoidance) motivation. This model has not yet been extended to high approach-motivation sexual stimuli, which may represent an important model of reward system function. Sixty-five participants viewed a neutral and a sexually motivating film while their EEG was recorded, and reported their sexual feelings after each film. Greater alpha power in the left hemisphere during sexually motivated states was evident. A positive relationship between self-reported mental sexual arousal and alpha asymmetry was identified, where coherence between these indicators was higher in women. Notably, coherence was stronger when mental versus physical sexual arousal was rated. Alpha asymmetry appears to offer a new method for further examining this novel coherence pattern across men and women. Copyright © 2014 Society for Psychophysiological Research.

There is currently much debate about whether the precise role of the hippocampus in scene processing is predominantly constructive, perceptual, or mnemonic. Here, we developed a novel experimental paradigm designed to control for general perceptual and mnemonic demands, thus enabling us to specifically vary the requirement for constructive processing. We tested the ability of patients with selective bilateral hippocampal damage and matched control participants to detect either semantic (e.g., an elephant with butterflies for ears) or constructive (e.g., an endless staircase) violations in realistic images of scenes. Thus, scenes could be semantically or constructively 'possible' or 'impossible'. Importantly, general perceptual and memory requirements were similar for both types of scene. We found that the patients performed comparably to control participants when deciding whether scenes were semantically possible or impossible, but were selectively impaired at judging if scenes were constructively possible or impossible. Post-task debriefing indicated that control participants constructed flexible mental representations of the scenes in order to make constructive judgements, whereas the patients were more constrained and typically focused on specific fragments of the scenes, with little indication of having constructed internal scene models. These results suggest that one contribution the hippocampus makes to scene processing is to construct internal representations of spatially coherent scenes, which may be vital for modelling the world during both perception and memory recall. © 2016 The Authors.

Associations between personality traits, mental wellbeing and good health behaviours were examined to understand further the social and psychological context of the health divide. In a cross-sectional study, 666 subjects recruited from areas of high and low socioeconomic deprivation had personality traits and mental wellbeing assessed, and lifestyle behaviours quantified. Regression models (using deprivation as a moderating variable) assessed the extent to which personality traits and mental wellbeing predicted health behaviour. Deprived (vs. affluent) subjects exhibited similar levels of extraversion but higher levels of neuroticism and psychoticism, more hopelessness, less sense of coherence, lower self-esteem and lower self-efficacy (all P< 0.001). They ate less fruit and vegetables, smoked more and took less aerobic exercise (all P< 0.001). In the deprived group, personality traits were significantly more important predictors of mental wellbeing than in the least deprived group (P< 0.01 for interaction), and mental wellbeing and extraversion appeared more strongly related to good health behaviours. Persistence of a social divide in health may be related to interactions between personality, mental wellbeing and the adoption of good health behaviours in deprived areas. Effectiveness of health messages may be enhanced by accommodating the variation in the levels of extraversion, neuroticism, hopelessness and sense of coherence.

We investigated mental risk factors such as symptoms of burnout and sense of coherence in students of dental medicine at the University of Erlangen in the context of a learning type survey. Our aim was to assess the presence of analogies to the results we had previously determined for students of human medicine. We surveyed a total of 163 dentistry students during the first 2.5 years, up to the first state examination. To ensure comparability, the data were collected from all students at the beginning of each semester. Standardized, validated questionnaires on burnout symptoms (Burnout Screening Scales; BOSS-II), sense of coherence (Sense of Coherence Scale; SOC-L9) and learning type according to Kolb were used in the survey. A total of about 90% of the students provided responses to the voluntary survey. The extent and manifest dynamics of the stress levels observed can be characterized as dramatic. Having started out at cognitive and emotional stress levels typical of the normal populace, a massive deterioration of these parameters was observed in the students by the time they were facing their first state examination in the 5th semester. At the same time, their sense of coherence also suffered a pronounced drop-off. No significant learning type-correlated differences were determined in a mean comparison of the measured parameters. Based on the results obtained, we see a need for preventive course offerings to students of dentistry to reduce the prevalence of mental disorders in this group. We discern additional potential for enhancement of mental health with courses more specifically geared to the different learning styles among the students. Copyright © 2016 Elsevier GmbH.

There is an increased interest in improving the physical health of people with mental illness. Little is known about implementing health promotion interventions in adult mental health organisations where many users also have physical health problems. The literature suggests that contextual factors are important for implementation in community settings. This study focused on the change process and analysed the implementation of a structural health promotion intervention in community mental health organisations in different contexts in Denmark. The study was based on a qualitative multiple-case design and included two municipal and two regional provider organisations. Data were various written sources and 13 semi-structured interviews with 22 key managers and frontline staff. The analysis was organised around the four main constructs of Normalization Process Theory: Coherence, Cognitive Participation, Collective Action, and Reflexive Monitoring. Coherence: Most respondents found the intervention to be meaningful in that the intervention fitted well into existing goals, practices and treatment approaches. Cognitive Participation: Management engagement varied across providers and low engagement impeded implementation. Engaging all staff was a general problem although some of the initial resistance was apparently overcome. Collective Action: Daily enactment depended on staff being attentive and flexible enough to manage the complex needs and varying capacities of users. Reflexive Monitoring: During implementation, staff evaluations of the progress and impact of the intervention were mostly informal and ad hoc and staff used these to make on-going adjustments to activities. Overall, characteristics of context common to all providers (work force and user groups) seemed to be more important for implementation than differences in the external political-administrative context. In terms of research, future studies should adopt a more bottom-up, grounded description of context and pay closer attention to the interplay between different dimensions of implementation. In terms of practice, future interventions need to better facilitate the translation of the initial sense of general meaning into daily practice by active local management support that occurs throughout the implementation process and that systematically connects the intervention to existing practices.

Sense of Coherence as a Determinant of Psychological Well-Being Across Professional Groups of Aid Workers Exposed to War Trauma.

The present study aims to test whether sense of coherence (SOC) acts as a determinant of positive psychological functioning in aid workers directly exposed to warfare. Specifically, we performed multiple regression analyses to compare different groups of aid workers in terms of the effects of SOC and cumulative trauma on their psychological distress. Palestinian helpers, both professional and non-professional (N = 159) completed three self-reported measures: the General Health questionnaire, Sense of Coherence Scale, and Impact of Events Scale. The findings bear out the predictive power of SOC and posttraumatic stress disorder (PTSD) in relation to mental health across different professional groups. In particular, volunteers without a specific professional profile, psychiatrists, medical doctors, and less markedly counselors seemed to protect their mental health through a SOC. Clinical implications and recommendations for training and supervision are discussed. © The Author(s) 2015.

The family empowerment program: an interdisciplinary approach to working with multi-stressed urban families.

The family empowerment program (FEP) is a multi-systemic family therapy program that partners multi-stressed families with an interdisciplinary resource team while remaining attached to a "traditional" mental health clinic. The rationale for this model is that far too often, families presenting at community mental health centers struggle with multiple psychosocial forces, for example problems with housing, domestic violence, child care, entitlements, racism, substance abuse, and foster care, as well as chronic medical and psychiatric illnesses, that exacerbate symptoms and impact traditional service delivery and access to effective treatment. Thus, families often experience fragmented care and are involved with multiple systems with contradictory and competing agendas. As a result, services frequently fail to harness the family's inherent strengths. The FEP partners the family with a unified team that includes representatives from Entitlements Services, Family Support and Parent Advocacy, and Clinical Staff from the agency's Outpatient Mental Health Clinic practicing from a strength-based family therapy perspective. The goal of the FEP is to support the family in achieving their goals. This is accomplished through co-construction of a service plan that addresses the family's needs in an efficient and coherent manner-emphasizing family strengths and competencies and supporting family self-sufficiency. © FPI, Inc.

Mental health and positive change among Japanese mothers of children with intellectual disabilities: Roles of sense of coherence and social capital.

PubMed

Kimura, Miyako; Yamazaki, Yoshihiko

2016-12-01

We investigated predictors of mental health and positive change among mothers of children with intellectual disabilities in Japan based on the concept of the Double ABCX model. We used variables of having a child with autism spectrum disorder (ASD) and dissatisfaction with systems as stressors, availability of social support and social capital (SC) as existing resources, sense of coherence (SOC) as appraisal of the stressor, and mental health and positive change as adaptation. A self-administered questionnaire was distributed to 10 intellectual disability-oriented special needs schools in Tokyo, and obtained 613 responses from mothers of children under age 20 attending these schools. The results showed that our Double ABCX model explained 46.0% of the variance in mothers' mental health and 38.9% of the variance in positive change. The most powerful predictor of this model was SOC, and SC may be directly and indirectly related to maternal mental health and positive change through mothers' SOC. Increasing opportunity for interaction between neighbors and family of children with disabilities may be one effective way to enhance SOC through SC. Since maternal SOC, SC, mental health, and positive change were significantly correlated with each other, synergy among these elements could be expected. Copyright © 2016 Elsevier Ltd.

The present study had two aims: (a) to replicate previous findings regarding the characteristics of sudden gains (SGs) in psychotherapy under routine clinical conditions and (b) to examine whether clients' narrative meaning-making processes were associated with SGs in mental health. 54 psychotherapy clients completed the Systemic Therapy Inventory of Change (Pinsof et al., 2009) and wrote private narratives prior to beginning treatment and between every session for 12 assessment points over the course of psychotherapy for a variety of presenting problems. Clients' narratives were coded using existing systems (Adler, 2012; A. M. Hayes, Feldman, & Goldfried, 2006) to assess their content in eight themes: processing, avoidance, coherence, positive self, negative self, agency, hope, and hopelessness. The prevalence, magnitude, and timing of SGs in mental health observed in the present study were similar to those observed in prior research. Two narrative meaning-making processes-processing and coherence-were significantly associated with SGs in mental health. The present study significantly extends prior research on SGs, replicating the characteristics of these gains in routine clinical conditions with a measure of general functioning and identifying two narrative meaning-making processes that are associated with SGs in mental health.

Karliner, Westrich, Shedler, and Mayman (1996) developed the Early Memory Index (EMI) to assess mental health, narrative coherence, and traumatic experiences in reports of early memories. We assessed the convergent validity of EMI scales with data from 103 women from an urban primary care clinic (Study 1) and data from 48 women and 24 men from a suburban primary care clinic (Study 2). Patients provided early memory narratives and completed self-report measures of psychopathology, trauma, and health care utilization. In both studies, lower scores on the Mental Health scale and higher scores on the Traumatic Experiences scale were related to higher scores on measures of psychopathology and childhood trauma. Less consistent associations were found between the Mental Health and Traumatic Experiences scores and measures of health care utilization. The Narrative Coherence scale showed inconsistent relationships across measures in both samples. In analyses assessing the overall fit between hypothesized and actual correlations between EMI scores and measures of psychopathology, severity of trauma symptoms, and health care utilization, the Mental Health scale of the EMI demonstrated stronger convergent validity than the EMI Traumatic Experiences scale. The results provide support for the convergent validity of the Mental Health scale of the EMI.

Using texts in science education: cognitive processes and knowledge representation.

PubMed

2010-04-23

Texts form a powerful tool in teaching concepts and principles in science. How do readers extract information from a text, and what are the limitations in this process? Central to comprehension of and learning from a text is the construction of a coherent mental representation that integrates the textual information and relevant background knowledge. This representation engenders learning if it expands the reader's existing knowledge base or if it corrects misconceptions in this knowledge base. The Landscape Model captures the reading process and the influences of reader characteristics (such as working-memory capacity, reading goal, prior knowledge, and inferential skills) and text characteristics (such as content/structure of presented information, processing demands, and textual cues). The model suggests factors that can optimize--or jeopardize--learning science from text.

In the occupational health field, it is important to know how workload influences mental health. Overtime work and job strain appear to affect the mental health status of workers. Sense of coherence (SOC) may mediate the relationship between work stress and mental health. Since SOC represents a personal ability to manage psychological stressors, we hypothesized that a strong SOC would modify the adverse effect of an objective measure of overtime work on mental health. A total of 1,558 Japanese workers employed in an information technology company were asked to complete a 3-item SOC Questionnaire and 28-item General Health Questionnaire (GHQ) to assess mental health status. Workload was assessed by the actual amount of overtime work hours recorded by the company. Multiple regression analysis revealed a main effect of overtime work (β=0.08, p=0.0003) and SOC scores (β=0.41, p <0.0001) on GHQ scores. There was a tendency toward interaction between overtime work and SOC scores (β=0.05, p=0.051). Simple slope analysis supported this association (-1 SD below the mean, simple slope=0.04, SE=0.01, p < 0.0001; +1 SD above the mean, simple slope=0.01, SE=0.01, p=0.188). These results suggest that SOC buffers the mental health impacts of workload as measured by an objective index of overtime work, and should be considered when assessing the effects of workload on mental health.

Coherent communication with continuous quantum variables

The coherent bit (cobit) channel is a resource intermediate between classical and quantum communication. It produces coherent versions of teleportation and superdense coding. We extend the cobit channel to continuous variables by providing a definition of the coherent nat (conat) channel. We construct several coherent protocols that use both a position-quadrature and a momentum-quadrature conat channel with finite squeezing. Finally, we show that the quality of squeezing diminishes through successive compositions of coherent teleportation and superdense coding.

To explore relationships of socio-demographic variables, health behaviours, environmental characteristics and personal factors, with physical and mental health variables in persons with morbid obesity, and to compare their health-related quality of life (HRQoL) scores with scores from the general population. A cross-sectional correlation study design was used. Data were collected by self-reported questionnaire from adult patients within the first 2 days of commencement of a mandatory educational course. Of 185 course attendees, 142 (76.8%) volunteered to participate in the study. Valid responses on all items were recorded for 128 participants. HRQoL was measured with the Short Form 12v2 from which physical (PCS) and mental component summary (MCS) scores were computed. Other standardized instruments measured regular physical activity, social support, self-esteem, sense of coherence, self-efficacy and coping style. Respondents scored lower on all the HRQoL sub-domains compared with norms. Linear regression analyses showed that personal factors that included self-esteem, self-efficacy, sense of coherence and coping style explained 3.6% of the variance in PCS scores and 41.6% in MCS scores. Personal factors such as self-esteem, sense of coherence and a high approaching coping style are strongly related to mental health in obese persons.

Teaching profession is characterised by an above-average rate of psychosomatic and mental health impairment due to work-related stress. The aim of the study was to identify predictors of mental health in female teachers. A sample of 630 female teachers (average age 47 ± 7 years) participated in a screening diagnostic inventory. Mental health was surveyed with the General Health Questionnaire GHQ-12. The following parameters were measured: specific work conditions (teacher-specific occupational history), scales of the Effort-Reward-Imbalance (ERI) Questionnaire as well as cardiovascular risk factors, physical complaints (BFB) and personal factors such as inability to recover (FABA), sense of coherence (SOC) and health behaviour. First, mentally fit (MH(+)) and mentally impaired teachers (MH(-)) were differentiated based on the GHQ-12 sum score (MH(+): < 5; MH(-): ≥ 5); 18% of the teachers showed evidence of mental impairment. There were no differences concerning work-related and cardiovascular risk factors as well as health behaviour between MH(+) and MH(-). Binary logistic regressions identified 4 predictors that showed a significant effect on mental health. The effort-reward-ratio proved to be the most relevant predictor, while physical complaints as well as inability to recover and sense of coherence were identified as advanced predictors (explanation of variance: 23%). Contrary to the expectations, classic work-related factors can hardly contribute to the explanation of mental health. Additionally, cardiovascular risk factors and health behaviour have no relevant influence. However, effort-reward-ratio, physical complaints and personal factors are of considerable influence on mental health in teachers. These relevant predictors should become a part of preventive arrangements for the conservation of teachers' health in the future.

A seismic coherency method using spectral amplitudes

NASA Astrophysics Data System (ADS)

Sui, Jing-Kun; Zheng, Xiao-Dong; Li, Yan-Dong

2015-09-01

Seismic coherence is used to detect discontinuities in underground media. However, strata with steeply dipping structures often produce false low coherence estimates and thus incorrect discontinuity characterization results. It is important to eliminate or reduce the effect of dipping on coherence estimates. To solve this problem, time-domain dip scanning is typically used to improve estimation of coherence in areas with steeply dipping structures. However, the accuracy of the time-domain estimation of dip is limited by the sampling interval. In contrast, the spectrum amplitude is not affected by the time delays in adjacent seismic traces caused by dipping structures. We propose a coherency algorithm that uses the spectral amplitudes of seismic traces within a predefined analysis window to construct the covariance matrix. The coherency estimates with the proposed algorithm is defined as the ratio between the dominant eigenvalue and the sum of all eigenvalues of the constructed covariance matrix. Thus, we eliminate the effect of dipping structures on coherency estimates. In addition, because different frequency bands of spectral amplitudes are used to estimate coherency, the proposed algorithm has multiscale features. Low frequencies are effective for characterizing large-scale faults, whereas high frequencies are better in characterizing small-scale faults. Application to synthetic and real seismic data show that the proposed algorithm can eliminate the effect of dip and produce better coherence estimates than conventional coherency algorithms in areas with steeply dipping structures.

Objectives We aimed to investigate how mental distress was associated with pain and injuries in a convenience sample of construction workers. Methods A cross-sectional, mental health assessment was conducted in a convenience sample of construction workers (N=172). A subsample participated in a clinical interview (N=10). We used a cut-off (≥1.50) on HSCL-25 to determine substantial mental distress and determined associations with pain and injury outcomes. Results The prevalence of substantial mental distress was 16 % in the workers. This was supported by follow-up clinical interviews where nine out of ten workers fulfilled the criteria for a mental disorder. Substantial mental distress was associated with both injury rate and self-reported pain. Conclusion This pilot study strongly suggests the need for rigorous studies on construction worker mental health, and how it affects their work and wellbeing. PMID:24064778

2009-10-01

To examine if sense of coherence (SOC) can reduce the adverse effects of job stress on mental health status, self-administered questionnaires were distributed among 740 workers in a manufacturing industry. The questionnaire contained SOC, Job Content Questionnaire (JCQ), and General Health Questionnaire (GHQ-12). Complete answers were recovered from 466 workers (62.8%), consisting of 387 males and 79 females, with ages of 45.1 + or - 12.0 yr, and used for the analysis. The logistic regression analysis revealed the followings: Both for males and females, high GHQ was significantly associated with scores on SOC and JCQ job demand subscale, i.e. the mental health status was adversely related to job demand whereas it was positively associated with SOC. Similarly, the mental health status was affected adversely by managerial work in males, whereas was positively by co-workers support in females. Thus, high SOC enables workers to cope with their job demand, which is a potent job stressor, indicating that SOC is an important factor determining their coping ability to job stress for both genders. Male managerial employees may cope with their strong job stress because of high SOC, protecting their mental health status. Social support seems also significant for prevention of mental well-being of female workers from work-related stressors.

Physical and mental impairments represent the two largest health condition categories for which workers receive Social Security disability benefits. Comprehensive assessment of physical and mental impairments should include aspects beyond medical conditions such as a person’s underlying capabilities as well as activity demands relevant to the context of work. The objective of this paper is to describe the initial conceptual stages of developing new measurement instruments of behavioral health and physical functioning relevant for Social Security work disability evaluation purposes. To outline a clear conceptualization of the constructs to be measured, two content models were developed using structured and informal qualitative approaches. We performed a structured literature review focusing on work disability and incorporating aspects of the International Classification of Functioning, Disability, and Health (ICF) as a unifying taxonomy for framework development. Expert interviews provided advice and consultation to enhance face validity of the resulting content models. The content model for work-related behavioral health function identifies five major domains (1) Behavior Control, (2) Basic Interactions, (3) Temperament and Personality, (4) Adaptability, and (5) Workplace Behaviors. The content model describing physical functioning includes three domains (1) Changing and Maintaining Body Position, (2) Whole Body Mobility, and (3) Carrying, Moving and Handling Objects. These content models informed subsequent measurement properties including item development, measurement scale construction, and provided conceptual coherence guiding future empirical inquiry. The proposed measurement approaches show promise to comprehensively and systematically assess physical and behavioral health functioning relevant to work. PMID:23548543

Integration Processes Compared: Cortical Differences for Consistency Evaluation and Passive Comprehension in Local and Global Coherence.

Egidi, Giovanna; Caramazza, Alfonso

2016-10-01

This research studies the neural systems underlying two integration processes that take place during natural discourse comprehension: consistency evaluation and passive comprehension. Evaluation was operationalized with a consistency judgment task and passive comprehension with a passive listening task. Using fMRI, the experiment examined the integration of incoming sentences with more recent, local context and with more distal, global context in these two tasks. The stimuli were stories in which we manipulated the consistency of the endings with the local context and the relevance of the global context for the integration of the endings. A whole-brain analysis revealed several differences between the two tasks. Two networks previously associated with semantic processing and attention orienting showed more activation during the judgment than the passive listening task. A network previously associated with episodic memory retrieval and construction of mental scenes showed greater activity when global context was relevant, but only during the judgment task. This suggests that evaluation, more than passive listening, triggers the reinstantiation of global context and the construction of a rich mental model for the story. Finally, a network previously linked to fluent updating of a knowledge base showed greater activity for locally consistent endings than inconsistent ones, but only during passive listening, suggesting a mode of comprehension that relies on a local scope approach to language processing. Taken together, these results show that consistency evaluation and passive comprehension weigh differently on distal and local information and are implemented, in part, by different brain networks.

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

We generalize the technique called as the integration within a normally ordered product (IWOP) of operators referring to the creation and annihilation operators of the harmonic oscillator coherent states to a new operatorial approach, i.e. the diagonal ordering operation technique (DOOT) about the calculations connected with the normally ordered product of generalized creation and annihilation operators that generate the generalized hypergeometric coherent states. We apply this technique to the coherent states of the Morse oscillator including the mixed (thermal) state case and get the well-known results achieved by other methods in the corresponding coherent state representation. Also, in the lastmore » section we construct the coherent states for the continuous dynamics of the Morse oscillator by using two new methods: the discrete–continuous limit, respectively by solving a finite difference equation. Finally, we construct the coherent states corresponding to the whole Morse spectrum (discrete plus continuous) and demonstrate their properties according the Klauder’s prescriptions.« less

Optimal quantum operations at zero energy cost

NASA Astrophysics Data System (ADS)

Chiribella, Giulio; Yang, Yuxiang

2017-08-01

Quantum technologies are developing powerful tools to generate and manipulate coherent superpositions of different energy levels. Envisaging a new generation of energy-efficient quantum devices, here we explore how coherence can be manipulated without exchanging energy with the surrounding environment. We start from the task of converting a coherent superposition of energy eigenstates into another. We identify the optimal energy-preserving operations, both in the deterministic and in the probabilistic scenario. We then design a recursive protocol, wherein a branching sequence of energy-preserving filters increases the probability of success while reaching maximum fidelity at each iteration. Building on the recursive protocol, we construct efficient approximations of the optimal fidelity-probability trade-off, by taking coherent superpositions of the different branches generated by probabilistic filtering. The benefits of this construction are illustrated in applications to quantum metrology, quantum cloning, coherent state amplification, and ancilla-driven computation. Finally, we extend our results to transitions where the input state is generally mixed and we apply our findings to the task of purifying quantum coherence.

The minimum uncertainty and other relations are evaluated in the framework of the coherent states of the damped harmonic oscillator. It is shown that the coherent states of the damped harmonic oscillator are the squeezed coherent states of the simple harmonic oscillator. The unitary operator is also constructed, and this connects coherent states with damped harmonic and simple harmonic oscillators.

Normal aging triggers deterioration in cognitive functions. Evidence has shown that these age-related changes concern also executive functions (EF) as well as temporal information processing (TIP) in a millisecond range. A considerable amount of literature data has indicated that each of these two functions sets a frame for our mental activity and may be considered in terms of embodied cognition due to advanced age. The present study addresses the question whether in elderly subjects the efficiency of TIP is related to individual differences in EF. The study involved 53 normal healthy participants aged from 65 to 78. In these subjects TIP was assessed by sequencing abilities measured with temporal-order threshold (TOT). It is defined as the minimum time gap separating two auditory stimuli presented in rapid succession which is necessary for a subject to report correctly their temporal order, thus the relation 'before-after.' The EF were assessed with regard to the efficiency of the executive planning measured with the Tower of London-Drexel University (TOL DX ) which has become a well-known EF task. Using Spearman's rank correlations we observed two main results. Firstly, the indices of the TOL DX indicated a coherent construct reflecting the effectiveness of executive planning in the elderly. Initiation time seemed dissociated from these coherent indices, which suggested a specific strategy of mental planning in the elderly based on on-line planning rather than on preplanning. Secondly, TOT was significantly correlated with the indices of TOL DX . Although some of these correlations were modified by subject's age, the correlation between TOT and the main index of TOL DX ( 'Total Move Score' ) was rather age resistant. These results suggest that normal aging may be characterized by an overlapping of deteriorated TIP and deteriorated EF.

According to Antonovsky's salutogenic concept, a strong sense of coherence is associated with physical and psychological health. The goal of this study was to analyze the association of Antonovsky's sense of coherence with physical and psychosocial health components in patients with hip and knee osteoarthritis before and after in- and outpatient rehabilitation. Prospective cohort study with 335 patients, 136 (41%) with hip and 199 (59%) with knee osteoarthritis. The outcome was measured by Short Form-36 (SF-36), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Sense of Coherence (SOC-13). Baseline scores of the SF-36 and WOMAC scales and the observed effect sizes after rehabilitation were correlated with the baseline SOC-13. These correlations of the SF-36 scales were compared to the Factor Score Coefficients for the Mental Component Summary of SF-36, which quantify the factor load on the psychosocial dimension. Predictive impact of the baseline SOC-13 for the SF-36 and WOMAC scales (baseline scores and effect sizes) was then determined by multivariate linear regression controlled for possible confounders. At baseline, the SOC-13 correlated with the WOMAC scores between r = 0.18 (stiffness) and r = 0.25 (pain) and with the SF-36 scores between r = 0.10 (physical functioning) and r = 0.53 (mental health). The correlation of these SF-36 correlation coefficients to the Factor Score Coefficient of the SF-36 Mental Component Summary was r = 0.95. The correlations for the effect sizes (baseline → discharge) with the baseline SOC-13 global score were all negative and varied between r = 0.00 (physical functioning) and r = -0.19 (social functioning). In the multivariate linear regression model, the explained variance of the SF-36 scores by the baseline SOC-13 increased continuously from physical to psychosocial health dimensions (from 12.9% to 29.8%). This gradient was consistently observed for both the baseline scores and the effect sizes. The results of the WOMAC were consistent with the physical health scales of SF-36. The sense of coherence was associated with psychosocial health dimensions but hardly with physical health. The higher the load of a scale on the psychosocial dimension the higher was its correlation to the sense of coherence. This is in contrast to the idea of Antonovsky who predicted high associations with both mental and physical health.

This paper presents a history of mental health nursing in Victoria, Australia from 1848 to the 1950's, or the asylum years to the era of the mental hospital. The research for this historical overview was conducted as part of a literature review for a mental health nursing doctoral thesis, which included an account of the evolution of the profession from asylum attendant to the present time. The literature reviewed for this project revealed a distinct lack of a coherent, chronological account of the historical development of mental health nursing in Victoria, and this paper seeks to address that knowledge gap.

Spaceborne radar interferometry for coastal DEM construction

2005-01-01

Topographic features in coastal regions including tidal flats change more significantly than landmass, and are characterized by extremely low slopes. High precision DEMs are required to monitor dynamic changes in coastal topography. It is difficult to obtain coherent interferometric SAR pairs especially over tidal flats mainly because of variation of tidal conditions. Here we focus on i) coherence of multi-pass ERS SAR interferometric pairs and ii) DEM construction from ERS-ENVISAT pairs. Coherences of multi-pass ERS interferograms were good enough to construct DEM under favorable tidal conditions. Coherence in sand dominant area was generally higher than that in muddy surface. The coarse grained coastal areas are favorable for multi-pass interferometry. Utilization of ERS-ENVISAT interferometric pairs is taken a growing interest. We carried out investigation using a cross-interferometric pair with a normal baseline of about 1.3 km, a 30 minutes temporal separation and the height sensitivity of about 6 meters. Preliminary results of ERS-ENVISAT interferometry were not successful due to baseline and unfavorable scattering conditions. ?? 2005 IEEE.

A Test of the Empirical Profile and Coherence of the DSM-5 Psychopathy Specifier.

The Diagnostic and Statistical Manual of Mental Disorders-5th edition (DSM-5; American Psychiatric Association, 2013) introduced a psychopathy specifier (DSM-5 PS) as part of the Section III diagnostic model of antisocial personality disorder. Designed to capture the construct of fearless dominance/boldness, the DSM-5 PS is assessed on the basis of the presence of low scores on traits of withdrawal and anxiousness, and high scores on attention seeking. These constructs have garnered attention in the past decade but are the subject of substantial debate as to their role in the conceptualization and assessment of psychopathy, given their limited relations to the maladaptive outcomes typically associated with this personality disorder. In the current study (N = 340 undergraduates; 170 informants), we examined the DSM-5 PS, both in composite form and its trait subscales, to investigate the degree to which the DSM-5 PS manifested empirical profiles associated with psychopathy and its maladaptive correlates. Consistent with prior fearless dominance/boldness research, the DSM-5 PS manifested limited relations with other components of psychopathy, symptoms of DSM-5 Section II and III antisocial personality disorder, and self- and informant-related impairment scores. When examined at the individual subscale level, the 3 DSM-5 PS subscales manifested only partially overlapping profiles and only 1 of the 3-Attention Seeking-demonstrated an association with maladaptivity (e.g., externalizing behaviors). These findings raise important concerns about the coherence and utility of the DSM-5 PS as a diagnostic specifier included in a psychiatric nosology.

To compare HRQOL of husbands of women with non-metastatic breast cancer to husbands of healthy women. Additionally, to examine the impact of Sense of Coherence (SOC), socio-demographic, and clinical variables, on HRQOL of spouses in both groups. This study used a comparative, matched, convenience sample. Husbands of women with non-metastatic breast cancer (n = 50), undergoing chemotherapy during 3-6 months after diagnoses and spouses of healthy women (n = 50) participated in a study. HRQOL was measured using the Medical Outcomes Study (MOS SF-36), and coping characteristics were measured using the Short Sense of Coherence scale. Socio-demographic factors, cancer stage, and treatments were collected. The groups were matched by age, education, employment (working/not working). The physical and mental component summary scores were dependent variables in the regression analysis. Physical and Mental Component Summary indexes in the study group were significantly lower than in the control group. Higher education level, greater income, or more daily working hours were associated with better physical health index (added 30% to explaining the variance). The only personal variable predicting the mental component of QOL was financial situation (added 7%). Higher SOC was associated with higher HRQOL. Disease and treatment characteristics were found to have no influence upon the husbands' QOL. While the main influence found in this study of a woman's breast cancer on her partner's quality of life is on the mental component, the partner's physical health should also be taken into account.

Two Decades of Structure Building

PubMed Central

Gernsbacher, Morton Ann

2014-01-01

During the past decade I have been developing a very simple framework for describing the cognitive processes and mechanisms involved in discourse comprehension. I call this framework the Structure Building Framework, and it is based on evidence provided during the first decade of discourse processing research. According to the Structure Building Framework, the goal of comprehension is to build coherent mental representations or structures. Comprehenders build each structure by first laying a foundation. Comprehenders develop mental structures by mapping on new information when that information coheres or relates to previous information. However, when the incoming information is less related, comprehenders shift and attach a new substructure. The building blocks of mental structures are memory nodes, which are activated by incoming stimuli and controlled by two cognitive mechanisms: suppression and enhancement. In this article, first I review the seminal work on which the Structure Building Framework is based (the first decade of structure building research); then I recount the research I have conducted to test the Structure Building Framework (the second decade of structure building research).

In this paper, first, by introducing Holstein-Primakoff representation of α-deformed algebra, we achieve the associated non-linear coherent states, including su(2) and su(1, 1) coherent states. Second, by using waveguide lattices with specific coupling coefficients between neighbouring channels, we generate these non-linear coherent states. In the case of positive values of α, we indicate that the Hilbert size space is finite; therefore, we construct this coherent state with finite channels of waveguide lattices. Finally, we study the field distribution behaviours of these coherent states, by using Mandel Q parameter.

Squeezed states: A geometric framework

NASA Technical Reports Server (NTRS)

Ali, S. T.; Brooke, J. A.; Gazeau, J.-P.

1992-01-01

A general definition of squeezed states is proposed and its main features are illustrated through a discussion of the standard optical coherent states represented by 'Gaussian pure states'. The set-up involves representations of groups on Hilbert spaces over homogeneous spaces of the group, and relies on the construction of a square integrable (coherent state) group representation modulo a subgroup. This construction depends upon a choice of a Borel section which has a certain permissible arbitrariness in its selection; this freedom is attributable to a squeezing of the defining coherent states of the representation, and corresponds in this way to a sort of gauging.

Single-Word Recognition Need Not Depend on Single-Word Features: Narrative Coherence Counteracts Effects of Single-Word Features that Lexical Decision Emphasizes.

2016-12-01

Research on reading comprehension of connected text emphasizes reliance on single-word features that organize a stable, mental lexicon of words and that speed or slow the recognition of each new word. However, the time needed to recognize a word might not actually be as fixed as previous research indicates, and the stability of the mental lexicon may change with task demands. The present study explores the effects of narrative coherence in self-paced story reading to single-word feature effects in lexical decision. We presented single strings of letters to 24 participants, in both lexical decision and self-paced story reading. Both tasks included the same words composing a set of adjective-noun pairs. Reading times revealed that the tasks, and the order of the presentation of the tasks, changed and/or eliminated familiar effects of single-word features. Specifically, experiencing the lexical-decision task first gradually emphasized the role of single-word features, and experiencing the self-paced story-reading task afterwards counteracted the effect of single-word features. We discuss the implications that task-dependence and narrative coherence might have for the organization of the mental lexicon. Future work will need to consider what architectures suit the apparent flexibility with which task can accentuate or diminish effects of single-word features.

Mo, Phoenix K H; Mak, Winnie W S

2008-08-01

The burdens related to mental illness have been increasingly recognized in many countries. Nevertheless, research in positive mental health behaviors remains scarce. This study utilizes the Predisposing, Reinforcing, and Enabling Causes in Education Diagnosis and Evaluation (PRECEDE) model to identify factors associated with mental health promoting behaviors and to examine the effects of these behaviors on mental well-being and quality of life among 941 adults in Hong Kong. Structural equation modeling shows that sense of coherence (predisposing factor), social support (reinforcing factor), and daily hassles (enabling factor) are significantly related to mental health promoting behaviors, which are associated with mental well-being and quality of life. Results of bootstrap analyses confirm the mediating role of mental health promoting behaviors on well-being and quality of life. The study supports the application of the PRECEDE model in understanding mental health promoting behaviors and demonstrates its relationships with well-being and quality of life.

To assess the degree of caregiver burden and family functioning among Taiwanese primary family caregivers of people with schizophrenia and to test its association with demographic characteristics, family demands, sense of coherence and family hardiness. Family caregiving is a great concern in mental illness. Yet, the correlates of caregiver burden and family functioning in primary family caregivers of individuals with schizophrenia still remain unclear. A cross-sectional descriptive study. A convenience sample of 137 primary family caregivers was recruited from two psychiatric outpatient clinics in Taiwan. Measures included a demographic information sheet and the Chinese versions of the Family Stressors Index, Family Strains Index, 13-item Sense of Coherence Scale, 18-item Caregiver Burden Scale, Family Hardiness Index and Family Adaptability, Partnership, Growth, Affection, and Resolve Index. Data analysis included descriptive statistics, Pearson's product-moment correlation coefficients, t-test, one-way analysis of variance and a stepwise multiple linear regression. Female caregivers, additional dependent relatives, increased family demands and decreased sense of coherence significantly increased caregiver burden, whereas siblings as caregivers reported lower degrees of burden than parental caregivers. Family caregivers with lower family demands, increased family hardiness and higher educational level had significantly enhanced family functioning. Sense of coherence was significantly correlated with family hardiness. Our findings highlighted the importance of sense of coherence and family hardiness in individual and family adaptation. Special attention needs to focus on therapeutic interventions that enhance sense of coherence and family hardiness, thereby improving the perception of burden of care and family functioning. Given the nature of family caregiving in schizophrenia, understanding of correlates of caregiver burden and family functioning would help provide useful avenues for the development of family-focused intervention in psychiatric mental health nursing practice. © 2014 John Wiley & Sons Ltd.

Neuronal bases of structural coherence in contemporary dance observation.

PubMed

Bachrach, Asaf; Jola, Corinne; Pallier, Christophe

2016-01-01

The neuronal processes underlying dance observation have been the focus of an increasing number of brain imaging studies over the past decade. However, the existing literature mainly dealt with effects of motor and visual expertise, whereas the neural and cognitive mechanisms that underlie the interpretation of dance choreographies remained unexplored. Hence, much attention has been given to the action observation network (AON) whereas the role of other potentially relevant neuro-cognitive mechanisms such as mentalizing (theory of mind) or language (narrative comprehension) in dance understanding is yet to be elucidated. We report the results of an fMRI study where the structural coherence of short contemporary dance choreographies was manipulated parametrically using the same taped movement material. Our participants were all trained dancers. The whole-brain analysis argues that the interpretation of structurally coherent dance phrases involves a subpart (superior parietal) of the AON as well as mentalizing regions in the dorsomedial prefrontal cortex. An ROI analysis based on a similar study using linguistic materials (Pallier et al., 2011) suggests that structural processing in language and dance might share certain neural mechanisms.

Public perceptions of the risks of an unfamiliar technology: The case of using nuclear energy sources for space missions

NASA Astrophysics Data System (ADS)

Maharik, Michael

This thesis addresses the public perception of the risk of a technology not widely known to laypeople. Its aims were (1) to characterize public perceptions of the risk of using nuclear energy in space and decisions related to this risk, and (2) to extend the 'mental model' methodology to studying public perception of unfamiliar, risky technologies. A model of the physical processes capable of creating risks from using nuclear energy sources in space was first constructed. Then, knowledge and beliefs related to this topic were elicited from three different groups of people. The generality of the findings was examined in a constructive replication with environmentally-oriented people. The possibility of involving the public in decision-making processes related to engineering macro-design was then investigated. Finally, a communication regarding these risk processes was developed and evaluated in an experiment comparing it with communications produced by NASA. Although they included large portions of the expert model, people's beliefs also had gaps and misconceptions. Respondents often used scientific terms without a clear understanding of what they meant. Respondents' mental models sometimes contained scattered and inconsistent entries. The impact of pre-existing mental models was clearly seen. Different groups of people had different patterns of knowledge and beliefs. Nevertheless, respondents expressed reasonable and coherent opinions on choices among engineering options. The CMU brochure, derived from the study of readers' existing mental models, provided a better risk communication tool than NASA's material, reflecting primarily experts' perspective. The better performance of subjects reading either brochure generally reflected adding knowledge on issues that they had not previously known, rather than correcting wrong beliefs. The communication study confirmed a hypothesis that improving knowledge on risk processes related to the use of a technology causes a more favorable attitude towards that technology. Recommendations related to the design and targeting of risk communication, and to public participation in decision-making on using new and risky technologies, are derived. Additional studies that will elicit laypeople's definitions of risk related to specific technologies, and link their detailed understanding of risk-development processes to the perceived dimensions of risk, are suggested.

Relating indices of knowledge structure coherence and accuracy to skill-based performance: Is there utility in using a combination of indices?

PubMed

Schuelke, Matthew J; Day, Eric Anthony; McEntire, Lauren E; Boatman, Jazmine Espejo; Wang, Xiaoqian; Kowollik, Vanessa; Boatman, Paul R

2009-07-01

The authors examined the relative criterion-related validity of knowledge structure coherence and two accuracy-based indices (closeness and correlation) as well as the utility of using a combination of knowledge structure indices in the prediction of skill acquisition and transfer. Findings from an aggregation of 5 independent samples (N = 958) whose participants underwent training on a complex computer simulation indicated that coherence and the accuracy-based indices yielded comparable zero-order predictive validities. Support for the incremental validity of using a combination of indices was mixed; the most, albeit small, gain came in pairing coherence and closeness when predicting transfer. After controlling for baseline skill, general mental ability, and declarative knowledge, only coherence explained a statistically significant amount of unique variance in transfer. Overall, the results suggested that the different indices largely overlap in their representation of knowledge organization, but that coherence better reflects adaptable aspects of knowledge organization important to skill transfer.

The right place? Users and professionals' constructions of the place's influence on personal recovery in community mental health services.

Femdal, Ingrid

2018-01-01

Current mental health policy emphasizes the importance of community-based service delivery for people with mental health problems to encompass personal recovery. The aim of this study is to explore how users and professionals construct the place's influence on personal recovery in community mental health services. This is a qualitative, interpretive study based on ten individual, semi-structured interviews with users and professionals, respectively. A discourse analysis inspired by the work of Foucault was used to analyze the interviews. The findings show how place can be constructed as a potential for and as a barrier against recovery. Constructions of the aim of the services matter when choosing a place for the services. Further, constructions of user-professional relationships and flexibility are important in the constructions of an appropriate place for the services. The aim of the service, the user-professional relationship, and flexibility in choosing place were essential in the participants' constructions. To find "the right place" for mental health services was constructed as context-sensitive and complex processes of assessment and co-determination. Trial registration The study is approved by the Regional Committee for Medical Research Ethics, Norway (REK-Midt 2011/2057).

Why are people with mental illness excluded from the rational suicide debate?

PubMed

Hewitt, Jeanette

2013-01-01

The topic of rational suicide is often approached with some trepidation by mental health professionals. Suicide prevention strategies are more likely to be seen as the domain of psychiatry and a wealth of psychiatric literature is devoted to identifying and managing suicide risk. Whether or not suicide can be deemed permissible is ostensibly linked to discussions of autonomy and mental capacity, and UK legislation directs that a patient's wishes must be respected with regard to treatment refusal where decisional capacity is intact. In the context of the care and treatment of those with physical disorders, extreme and untreatable physical suffering is likely to be accepted as rational grounds for suicide, where the person possesses cognitive coherence and an ability to realistically appreciate the consequences of his or her actions. In the case of those with serious mental disorder, the grounds for accepting that suicide is rational are however less clear-cut. Serious mental illness is typically conceived of as a coercive pressure which prevents rational deliberation and as such, the suicides of those with serious mental illness are considered to be substantially non-voluntary acts arising from constitutive irrationality. Therefore, where an appropriate clinician judges that a person with serious mental disorder is non-autonomous, suicide prevention is likely to be thought legally and morally justified. There are arguably, two questionable assumptions in the position that psychiatry adopts: Firstly, that psychogenic pain is in some way less real than physical pain and secondly, that mental illness invariably means that a desire to die is irrational and inauthentic. If it can be shown that some people with serious mental illness can be rational with regard to suicide and that psychological pain is of equal significance as physical suffering, then it may be possible to conclude that some persons with serious mental illness should not by definition be excluded from the class of those for whom rational suicide may be a coherent choice.

Travis, Frederick; Parim, Niyazi; Shrivastava, Amrita

2017-03-01

This study compared subjective experiences and EEG patterns in 37 subjects when listening to live Vedic recitation and when practicing Transcendental Meditation (TM). Content analysis of experiences when listening to Vedic recitation yielded three higher-order code. Experiences during Vedic recitation were: (1) deeper than during TM practice; (2) experienced as an inner process; and (3) characterized by lively silence. EEG patterns support these higher-order codes. Theta2 and alpha1 frontal, parietal, and frontal-parietal coherence were significantly higher when listening to Vedic recitation, than during TM practice. Theta2 coherence is seen when attending to internal mental processes. Higher theta2 coherence supports subjects' descriptions that the Vedic recitations were "not external sounds but internal vibrations." Alpha1 coherence is reported during pure consciousness experiences during TM practice. Higher alpha1 coherence supports subjects' descriptions that they "experienced a depth of experience, rarely experienced even during deep TM practice." These data support the utility of listening to Vedic recitation to culture deep inner experiences. Copyright © 2017 Elsevier Inc. All rights reserved.

Phase noise suppression for coherent optical block transmission systems: a unified framework.

Yang, Chuanchuan; Yang, Feng; Wang, Ziyu

2011-08-29

A unified framework for phase noise suppression is proposed in this paper, which could be applied in any coherent optical block transmission systems, including coherent optical orthogonal frequency-division multiplexing (CO-OFDM), coherent optical single-carrier frequency-domain equalization block transmission (CO-SCFDE), etc. Based on adaptive modeling of phase noise, unified observation equations for different coherent optical block transmission systems are constructed, which lead to unified phase noise estimation and suppression. Numerical results demonstrate that the proposal is powerful in mitigating laser phase noise.

Activating gender stereotypes during online spoken language processing: evidence from Visual World Eye Tracking.

PubMed

Pyykkönen, Pirita; Hyönä, Jukka; van Gompel, Roger P G

2010-01-01

This study used the visual world eye-tracking method to investigate activation of general world knowledge related to gender-stereotypical role names in online spoken language comprehension in Finnish. The results showed that listeners activated gender stereotypes elaboratively in story contexts where this information was not needed to build coherence. Furthermore, listeners made additional inferences based on gender stereotypes to revise an already established coherence relation. Both results are consistent with mental models theory (e.g., Garnham, 2001). They are harder to explain by the minimalist account (McKoon & Ratcliff, 1992) which suggests that people limit inferences to those needed to establish coherence in discourse.

Physical and mental impairments represent the 2 largest health condition categories for which workers receive Social Security disability benefits. Comprehensive assessment of physical and mental impairments should include aspects beyond medical conditions such as a person's underlying capabilities as well as activity demands relevant to the context of work. The objective of this article is to describe the initial conceptual stages of developing new measurement instruments of behavioral health and physical functioning relevant for Social Security work disability evaluation purposes. To outline a clear conceptualization of the constructs to be measured, 2 content models were developed using structured and informal qualitative approaches. We performed a structured literature review focusing on work disability and incorporating aspects of the International Classification of Functioning, Disability and Health as a unifying taxonomy for framework development. Expert interviews provided advice and consultation to enhance face validity of the resulting content models. The content model for work-related behavioral health function identifies 5 major domains: (1) behavior control, (2) basic interactions, (3) temperament and personality, (4) adaptability, and (5) workplace behaviors. The content model describing physical functioning includes 3 domains: (1) changing and maintaining body position, (2) whole-body mobility, and (3) carrying, moving, and handling objects. These content models informed subsequent measurement properties including item development and measurement scale construction, and provided conceptual coherence guiding future empirical inquiry. The proposed measurement approaches show promise to comprehensively and systematically assess physical and behavioral health functioning relevant to work.

This multidisciplinary work presents synopsis of theories in the search for common field-like fundamental principles of self-organisation and communication existing on quantum, cellular, and even social levels. Based on these fundamental principles, we formulate conceptually novel social neuroscience paradigm (OSIMAS), which envisages social systems emerging from the coherent neurodynamical processes taking place in the individual mind-fields. In this way, societies are understood as global processes emerging from the superposition of the conscious and subconscious mind-fields of individual members of society. For the experimental validation of the biologically inspired OSIMAS paradigm, we have designed a framework of EEG-based experiments. Initial baseline individual tests of spectral cross-correlations of EEG-recorded brainwave patterns for some mental states have been provided in this paper. Preliminary experimental results do not refute the main OSIMAS postulates. This paper also provides some insights for the construction of OSIMAS-based simulation models.

The consequences of tinnitus and tinnitus severity on cognition: A review of the behavioural evidence.

PubMed

Mohamad, Najibah; Hoare, Derek J; Hall, Deborah A

2016-02-01

People with tinnitus report anecdotal difficulties in mental concentration and psychological treatments for tinnitus advise on concentration difficulties and how to manage them. Yet the literature lacks any coherent discussion about what precise theoretical cognitive constructs might be mediating reported concentration problems. This review addresses this gap by describing and critically appraising the behavioural evidence for the effects of tinnitus on cognitive performance (namely working memory and attention). Empirical evidence is somewhat limited, but there is some support that tinnitus interferes with executive attention, and mixed support that it impairs working memory and selective attention. We highlight a number of methodological considerations to help drive the field forward and we propose a putative model of the complex inter-relationships between tinnitus, cognition and confounding factors. This model provides a basis for hypothesis testing. Copyright © 2015 The Authors. Published by Elsevier B.V. All rights reserved.

Multi-temporal coherent targets analysis is a high-precision and high-spatial-resolution monitoring method for urban surface deformation based on Differential Synthetic Aperture Radar (DInSAR), and has been successfully applied to measure land subsidence, landslide and strain accumulation caused by fault movement and so on. In this paper, the multi-temporal coherent targets analysis is used to study the settlement of subway area during the period of subway construction. The eastern extension of Shanghai Metro Line. 2 is taking as an example to study the subway settlement during the construction period. The eastern extension of Shanghai Metro Line. 2 starts from Longyang Road and ends at Pudong airport. Its length is 29.9 kilometers from east to west and it is a key transportation line to the Pudong Airport. 17 PalSAR images during 2007 and 2010 are applied to analyze and invert the settlement of the buildings nearby the subway based on the multi-temporal coherent targets analysis. But there are three significant deformation areas nearby the Line 2 between 2007 and 2010, with maximum subsidence rate up to 30 mm/y in LOS. The settlement near the Longyang Road station and Chuansha Town are both caused by newly construction and city expansion. The deformation of the coastal dikes suffer from heavy settlement and the rate is up to -30 mm/y. In general, the area close to the subway line is relatively stable during the construction period.

This study examines how education benefits health through social well-being in Hawaii where the centrality of community life is underscored. The 2007 Hawaii Health Survey with linked zip-code information was used to investigate the effects of education at both individual and neighborhood levels using mixed-effects models. Geographic Information System was applied to map the geographical distributions of education, social well-being, and health. It was found that individual-level education benefits mental health and its effects are largely mediated by respondents' employment status and their social well-being (social integration, social contribution, social actualization, and social coherence). Both individual and neighborhood-level education promotes physical health and their effects are partially mediated by economic well-being and two indicators of social well-being (social integration and social coherence). Results of this study suggest the independent effects of two levels of education on physical health and the importance of education and social well-being to both mental and physical health in the State of Hawaii.

Many female nurses leave their jobs because of major life events. However, the mental health status and related factors among nurses who assume the roles of wives and/or mothers have been insufficiently examined. Therefore we examined the mental health levels and related factors among such nurse. We conducted a questionnaire survey on 763 female nurses working at general hospitals with over 200 beds in Fukuoka Prefecture. Of 402 responses, 108 were divided into two groups: nurses who had left because of marriage, childbirth, or childrearing (leaving group), and those who had not (non-leaving group). The following were assessed: work satisfaction level, the Brief Job Stress Questionnaire, The General Health Questionnaire (GHQ) 28, and the Sense of Coherence (SOC) scale. Results showed that nurses who had assumed the roles of wives and/or mothers had lower mental health status than general women, and nurses who retained their jobs had higher mental health status and sense of comprehensibility on the SOC scale than those who left. Multiple regression analyses using the total GHQ score as an objective variable showed that only the sense of comprehensibility on the SOC scale correlated with mental health status in the non-leaving group. For the leaving group, having support, high work and life satisfaction levels, and several work stressors were correlated. These findings strongly suggest that to maintain and improve the mental health of nurses who assume the role of wives and/or mothers, greater support, higher satisfaction, reduced stressors, and maintenance and improvement of the sense of comprehensibility are required.

2016-01-01

The capacity to shift experiential perspective—from within one’s subjective experience onto that experience—is fundamental to being human. Scholars have long theorized that this metacognitive capacity—which we refer to as decentering—may play an important role in mental health. To help illuminate this mental phenomenon and its links to mental health, we critically examine decentering-related constructs and their respective literatures (e.g., self-distanced perspective, cognitive distancing, cognitive defusion). First, we introduce a novel metacognitive processes model of decentering. Specifically, we propose that, to varying degrees, decentering-related constructs reflect a common mental phenomenon subserved by three interrelated metacognitive processes: meta-awareness, disidentification from internal experience, and reduced reactivity to thought content. Second, we examine extant research linking decentering-related constructs and their underlying metacognitive processes to mental health. We conclude by proposing future directions for research that transcends decentering-related constructs in an effort to advance the field’s understanding of this facet of human experience and its role in (mal)adaptation.

Spatial path models with multiple indicators and multiple causes: mental health in US counties.

PubMed

Congdon, Peter

2011-06-01

This paper considers a structural model for the impact on area mental health outcomes (poor mental health, suicide) of spatially structured latent constructs: deprivation, social capital, social fragmentation and rurality. These constructs are measured by multiple observed effect indicators, with the constructs allowed to be correlated both between and within areas. However, in the scheme developed here, particular latent constructs may also be influenced by known variables, or, via path sequences, by other constructs, possibly nonlinearly. For example, area social capital may be measured by effect indicators (e.g. associational density, charitable activity), but influenced as causes by other constructs (e.g. area deprivation), and by observed features of the socio-ethnic structure of areas. A model incorporating these features is applied to suicide mortality and the prevalence of poor mental health in 3141 US counties, which are related to the latent spatial constructs and to observed variables (e.g. county ethnic mix).

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

Hypochondriasis Y-BOCS: a study of the psychometric properties of a clinician-administered semi-structured interview to assess hypochondriacal thoughts and behaviours.

2009-01-01

This study investigated the psychometric properties of the first clinician-administered semi-structured interview for assessing the severity of hypochondriacal symptoms. The Hypochondriasis Yale-Brown Obsessive-Compulsive Scale (H-YBOCS) consisted of three a priori dimensions: hypochondriacal obsessions, compulsions and avoidance. The 16-item interview was conducted with 112 participants with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, hypochondriasis. We analysed factor analytic structure, reliability, construct validity and sensitivity to change. Factor analysis supported a three-factor model similar to the a priori dimensions. Internal consistency ranged from satisfactory to good. Inter-rater reliability was excellent. The construct validity was low to moderate. The H-YBOCS was sensitive for measuring changes in symptom severity. The H-YBOCS is a (factorially) valid and coherent interview with a high level of agreement across different raters. The relatively low discriminant validity could be due to co-morbid anxiety and depressive disorders. Overall, the H-YBOCS seems to be a promising contribution to the assessment of hypochondriasis. *The hypochondriasis Y-BOCS is a feasible clinician rated interview to assess the severity of hypochondriacal complaints.

Counterfactual thinking in patients with amnesia

We often engage in counterfactual (CF) thinking, which involves reflecting on “what might have been.” Creating alternative versions of reality seems to have parallels with recollecting the past and imagining the future in requiring the simulation of internally generated models of complex events. Given that episodic memory and imagining the future are impaired in patients with hippocampal damage and amnesia, we wondered whether successful CF thinking also depends upon the integrity of the hippocampus. Here using two nonepisodic CF thinking tasks, we found that patients with bilateral hippocampal damage and amnesia performed comparably with matched controls. They could deconstruct reality, add in and recombine elements, change relations between temporal sequences of events, enabling them to determine plausible alternatives of complex episodes. A difference between the patients and control participants was evident, however, in the patients' subtle avoidance of CF simulations that required the construction of an internal spatial representation. Overall, our findings suggest that mental simulation in the form of nonepisodic CF thinking does not seem to depend upon the hippocampus unless there is the added requirement for construction of a coherent spatial scene within which to play out scenarios. © 2014 The Authors.

Moksnes, Unni K; Haugan, Gørill

2018-03-01

Resilience is seen as a vital resource for coping and mental health in adolescents. However, there is no universally accepted theory or definition of resilience, leading to considerable challenges regarding how to operationalise and measure this construct. The study aimed at providing further knowledge of the psychometric properties (dimensionality, construct validity and internal consistency) of the 28-item version of the Resilience Scale for Adolescents (READ) in N = 1183 Norwegian adolescents, 13-18 years old. Dimensionality of READ was tested using confirmatory factor analysis (CFA). Convergent validity and reliability were tested using Pearson's correlation analysis, Cronbach's alpha and composite reliability. The CFA supported a modified, 20-item, five-factor structure with high reliability, supporting the dimensionality and internal consistency of the instrument. Convergent validity was confirmed where all factors correlated in expected directions with measures of sense of coherence, self-esteem, stress and depression. The psychometric properties of the READ need to be further evaluated in adolescents; however, the results indicate that a modified 20-item version of READ is adequate for assessing resilience in the present sample of Norwegian adolescents. © 2017 Nordic College of Caring Science.

Limited role of spectra in dynamo theory: coherent versus random dynamos.

PubMed

Tobias, Steven M; Cattaneo, Fausto

2008-09-19

We discuss the importance of phase information and coherence times in determining the dynamo properties of turbulent flows. We compare the kinematic dynamo properties of three flows with the same energy spectrum. The first flow is dominated by coherent structures with nontrivial phase information and long eddy coherence times, the second has random phases and long-coherence time, the third has nontrivial phase information, but short coherence time. We demonstrate that the first flow is the most efficient kinematic dynamo, owing to the presence of sustained stretching and constructive folding. We argue that these results place limitations on the possible inferences of the dynamo properties of flows from the use of spectra alone, and that the role of coherent structures must always be accounted for.

Feeling "overloaded" and "shortcomings": milieu therapists' experiences of vulnerability in caring for severely mentally ill patients.

Milieu therapists' relationships with patients with severe mental illnesses are viewed as challenging. Elucidating vulnerability from their perspective in daily face-to-face encounters with patients might contribute to extending our knowledge about milieu therapists' vulnerability and the dynamics of the interaction between patients in mental health services and expertise in building caring and therapeutic relationships. The aim of this project was to study educated milieu therapists' experiences of their own vulnerability in their interactions with patients in mental health services. The data collection method was focus-group interviews. Thirteen part-time master's in mental health students (eight nurses, three social workers, two social educators) participated. All participants had experience with community or specialized mental health services (2-8 years). The milieu therapists mainly related their experiences of vulnerability to negative feelings elicited by challenging work conditions, disclosed as two main themes: 1) "overloaded", by the possibility of being physically and mentally hurt and the burdens of long-lasting close relationships; milieu therapists were extremely vulnerable because of their difficulty in protecting themselves; and 2) "shortcomings", connected to feelings of despair associated with not acting in concordance with their professional standards and insecurity about their skills to handle challenging situations, which was a threat to their professional integrity. There seemed to be coherence between vulnerability and professional inauthenticity. A misunderstanding that professionalism refers to altruism seems to increase milieu therapist vulnerability. Vulnerability in health care is of interest to multiple disciplines, and is of relevance for knowledge development in higher education. Extended knowledge and understanding about milieu therapists' vulnerability might strengthen their personal and professional integrity in professional practice in mental health services. Health care managers' focus on the supervision of individual professionals in practice and practical training is important. Further research on the coherence between vulnerability and professionalism is recommended.

Responding to the needs of the population suffering from severe mental disorders by a multifaceted territorial approach: Reorganization of the French mental health system.

2018-02-25

Organizing the management of severe mental disorders at the national level is a major challenge given the complexity of the disorders and the diversity of responses needed to address all the needs. A founding principle for the creation or development of measures consists in structuring care programs around functional and personal recovery, and not only clinical recovery. The fact that the French psychiatric field is currently being modernized by its missions being redefined within territorial mental health projects gives the opportunity to generalize these principles. This article illustrates how the creation of a hierarchical organization of psychosocial rehabilitation can (a) give more coherence to the part of the French mental health system, (b) improve the quality of care, and (c) promote social inclusion and recovery of people with severe mental disorders. © 2018 Wiley Periodicals, Inc.

Beyond Sally's missing marble: further development in children's understanding of mind and emotion in middle childhood.

Research on the development of theory of mind (ToM), the understanding of people in relation to mental states and emotions, has been a vibrant area of cognitive development research. Because the dominant focus has been addressing when children acquire a ToM, researchers have concentrated their efforts on studying the emergence of psychological understanding during infancy and early childhood. Here, the benchmark test has been the false-belief task, the awareness that the mind can misrepresent reality. While understanding false belief is a critical milestone achieved by the age of 4 or 5, children make further advances in their knowledge about mental states and emotions during middle childhood and beyond. Thus, a comprehensive understanding of children's sociocognitive abilities in older age groups is necessary to understand more fully the course of ToM development. The aim of this review is to outline continued development in ToM during middle childhood. In particular, we focus on children's understanding of interpretation-that different minds can construct different interpretations of the same reality. Additionally, we consider children's growing understanding of how mental states (thoughts, emotions, decisions) derive from personal experiences, cohere across time, and interconnect (e.g., thoughts shape emotions). We close with a discussion of the surprising paucity of studies investigating individual differences in ToM beyond age 6. Our hope is that this chapter will invigorate empirical interest in moving the pendulum toward the opposite research direction-toward exploring strengths, limitations, variability, and persistent errors in developing theories of mind across the life span. © 2015 Elsevier Inc.

We propose a constructive polarization modulation scheme for atomic clocks based on coherent population trapping (CPT). In this scheme, the polarization of a bichromatic laser beam is modulated between two opposite circular polarizations to avoid trapping the atomic populations in the extreme Zeeman sublevels. We show that if an appropriate phase modulation between the two optical components of the bichromatic laser is applied synchronously, the two CPT dark states which are produced successively by the alternate polarizations add constructively. Measured CPT resonance contrasts up to 20% in one-pulse CPT and 12% in two-pulse Ramsey-CPT experiments are reported, demonstrating the potentialmore » of this scheme for applications to high performance atomic clocks.« less

From the definition of the standard Perelomov coherent states we introduce the Perelomov number coherent states for any su(2) Lie algebra. With the displacement operator we apply a similarity transformation to the su(2) generators and construct a new set of operators which also close the su(2) Lie algebra, being the Perelomov number coherent states the new basis for its unitary irreducible representation. We apply our results to obtain the energy spectrum, the eigenstates and the partition function of two coupled oscillators. We show that the eigenstates of two coupled oscillators are the SU(2) Perelomov number coherent states of the two-dimensional harmonic oscillator with an appropriate choice of the coherent state parameters.

Partially coherent isodiffracting pulsed beams

2018-02-01

We investigate a class of isodiffracting pulsed beams, which are superpositions of transverse modes supported by spherical-mirror laser resonators. By employing modal weights that, for stationary light, produce a Gaussian Schell-model beam, we extend this standard model to pulsed beams. We first construct the two-frequency cross-spectral density function that characterizes the spatial coherence in the space-frequency domain. By assuming a power-exponential spectral profile, we then employ the generalized Wiener-Khintchine theorem for nonstationary light to derive the two-time mutual coherence function that describes the space-time coherence of the ensuing beams. The isodiffracting nature of the laser resonator modes permits all (paraxial-domain) calculations at any propagation distance to be performed analytically. Significant spatiotemporal coupling is revealed in subcycle, single-cycle, and few-cycle domains, where the partial spatial coherence also leads to reduced temporal coherence even though full spectral coherence is assumed.

Grounded Learning Experience: Helping Students Learn Physics through Visuo-Haptic Priming and Instruction

NASA Astrophysics Data System (ADS)

Huang, Shih-Chieh Douglas

In this dissertation, I investigate the effects of a grounded learning experience on college students' mental models of physics systems. The grounded learning experience consisted of a priming stage and an instruction stage, and within each stage, one of two different types of visuo-haptic representation was applied: visuo-gestural simulation (visual modality and gestures) and visuo-haptic simulation (visual modality, gestures, and somatosensory information). A pilot study involving N = 23 college students examined how using different types of visuo-haptic representation in instruction affected people's mental model construction for physics systems. Participants' abilities to construct mental models were operationalized through their pretest-to-posttest gain scores for a basic physics system and their performance on a transfer task involving an advanced physics system. Findings from this pilot study revealed that, while both simulations significantly improved participants' mental modal construction for physics systems, visuo-haptic simulation was significantly better than visuo-gestural simulation. In addition, clinical interviews suggested that participants' mental model construction for physics systems benefited from receiving visuo-haptic simulation in a tutorial prior to the instruction stage. A dissertation study involving N = 96 college students examined how types of visuo-haptic representation in different applications support participants' mental model construction for physics systems. Participant's abilities to construct mental models were again operationalized through their pretest-to-posttest gain scores for a basic physics system and their performance on a transfer task involving an advanced physics system. Participants' physics misconceptions were also measured before and after the grounded learning experience. Findings from this dissertation study not only revealed that visuo-haptic simulation was significantly more effective in promoting mental model construction and remedying participants' physics misconceptions than visuo-gestural simulation, they also revealed that visuo-haptic simulation was more effective during the priming stage than during the instruction stage. Interestingly, the effects of visuo-haptic simulation in priming and visuo-haptic simulation in instruction on participants' pretest-to-posttest gain scores for a basic physics system appeared additive. These results suggested that visuo-haptic simulation is effective in physics learning, especially when it is used during the priming stage.

Satanism, ritual abuse, and multiple personality disorder: a sociohistorical perspective.

PubMed

Mulhern, S

1994-10-01

During the past decade in North America, a growing number of mental health professionals have reported that between 25% and 50% of their patients in treatment for multiple personality disorder (MPD) have recovered early childhood traumatic memories of ritual torture, incestuous rape, sexual debauchery, sacrificial murder, infanticide, and cannibalism perpetrated by members of clandestine satanic cults. Although hundreds of local and federal police investigations have failed to corroborate patients' therapeutically constructed accounts, because the satanic etiology of MPD is logically coherent with the neodissociative, traumatic theory of psychopathology, conspiracy theory has emerged as the nucleus of a consistent pattern of contemporary clinical interpretation. Resolutely logical and thoroughly operational, ultrascientific psychodemonology remains paradoxically oblivious to its own irrational premises. When the hermetic logic of conspiracy theory is stripped away by historical and socio/psychological analysis, however, the hypothetical perpetrators of satanic ritual abuse simply disappear, leaving in their wake the very real human suffering of all those who have been caught up in the social delusion.

The so-called "sense of coherence" (SOC) is the central idea of Antonovsky's concept of salutogenesis. The structure and the meaning of SOC for a person's ability to cope with stress are discussed as well as the overall health-promoting effect of SOC. At the end of the study's first part the question of proving the SOC empirically and of the SOC's construct validity are critically discussed. The second part of the article demonstrates the relevance of salutogenic mechanisms for psychiatry and neurology, especially regarding the social aspects of both disciplines. Health promotion and disease prevention are already important issues in the Mental Health Community. But also in neurology, which is much more grounded in the physical medicine than psychiatry, the concept of salutogenesis can help patients to prevent illness or to cope better with the consequences of diseases. Finally, the necessity to supply the current health care system in psychiatry and neurology with much more salutogenic input is questioned.

A psychological model of mental disorder.

PubMed

Kinderman, Peter

2005-01-01

A coherent conceptualization of the role of psychological factors is of great importance in understanding mental disorder. Academic articles and professional reports alluding to psychological models of the etiology of mental disorder are becoming increasingly common, and there is evidence of a marked policy shift toward the provision of psychological therapies and interventions. This article discusses the relationship between biological, social, and psychological factors in the causation and treatment of mental disorder. It argues that simple biological reductionism is not scientifically justified, and also that the specific role of psychological processes within the biopsychosocial model requires further elaboration. The biopsychosocial model is usually interpreted as implying that biological, psychological, and social factors are co-equal partners in the etiology of mental disorder. The psychological model of mental disorder presented here suggests that disruption or dysfunction in psychological processes is a final common pathway in the development of mental disorder. These processes include, but are not limited to, cognitive processes. The model proposes that biological and social factors, together with a person's individual experiences, lead to mental disorder through their conjoint effects on those psychological processes. Implications for research, interventions, and policy are discussed.

The effects of extra-low-frequency atmospheric pressure oscillations on human mental activity

NASA Astrophysics Data System (ADS)

Delyukov, A. A.; Didyk, L.

Slight atmospheric pressure oscillations (APO) in the extra-low-frequency range below 0.1 Hz, which frequently occur naturally, can influence human mental activity. This phenomenon has been observed in experiments with a group of 12 healthy volunteers exposed to experimentally created APO with amplitudes 30-50 Pa in the frequency band 0.011-0.17 Hz. Exposure of the subjects to APO for 15-30 min caused significant changes in attention and short-term memory functions, performance rate, and mental processing flexibility. The character of the response depended on the APO frequency and coherence. Periodic APO promoted purposeful mental activity, accompanied by an increase in breath-holding duration and a slower heart rate. On the other hand, quasi-chaotic APO, similar to the natural perturbations of atmospheric pressure, disrupted mental activity. These observations suggest that APO could be partly responsible for meteorosensitivity in humans.

Organic unity theory: an integrative mind-body theory for psychiatry.

PubMed

Goodman, A

1997-12-01

The potential of psychiatry as an integrative science has been impeded by an internal schism that derives from the duality of mental and physical. Organic unity theory is proposed as a conceptual framework that brings together the terms of the mind-body duality in one coherent perspective. Organic unity theory is braided of three strands: identity, which describes the relationship between mentally described events and corresponding physically described events; continuity, which describes the linguistic-conceptual system that contains both mental and physical terms; and dialectic, which describes the relationship between the empirical way of knowing that is associated with the physical domain of the linguistic-conceptual system and the hermeneutic way of knowing that is associated with the mental domain. Each strand represents an integrative formulation that resolves an aspect of mental-physical dualism into an underlying unity. After the theory is presented, its implications for psychiatry are briefly considered.

Coherent Waves in Seismic Researches

Emanov, A.; Seleznev, V. S.

2013-05-01

Development of digital processing algorithms of seismic wave fields for the purpose of useful event picking to study environment and other objects is the basis for the establishment of new seismic techniques. In the submitted paper a fundamental property of seismic wave field coherence is used. The authors extended conception of coherence types of observed wave fields and devised a technique of coherent component selection from observed wave field. Time coherence and space coherence are widely known. In this paper conception "parameter coherence" has been added. The parameter by which wave field is coherent can be the most manifold. The reason is that the wave field is a multivariate process described by a set of parameters. Coherence in the first place means independence of linear connection in wave field of parameter. In seismic wave fields, recorded in confined space, in building-blocks and stratified mediums time coherent standing waves are formed. In prospecting seismology at observation systems with multiple overlapping head waves are coherent by parallel correlation course or, in other words, by one measurement on generalized plane of observation system. For detail prospecting seismology at observation systems with multiple overlapping on basis of coherence property by one measurement of area algorithms have been developed, permitting seismic records to be converted to head wave time sections which have neither reflected nor other types of waves. Conversion in time section is executed on any specified observation base. Energy storage of head waves relative to noise on basis of multiplicity of observation system is realized within area of head wave recording. Conversion on base below the area of wave tracking is performed with lack of signal/noise ratio relative to maximum of this ratio, fit to observation system. Construction of head wave time section and dynamic plots a basis of automatic processing have been developed, similar to CDP procedure in method of reflected waves. With use of developed algorithms of head wave conversion in time sections a work of studying of refracting boundaries in Siberia have been executed. Except for the research by method of refracting waves, the conversion of head waves in time sections, applied to seismograms of reflected wave method, allows to obtain information about refracting horizons in upper part of section in addition to reflecting horizons data. Recovery method of wave field coherent components is the basis of the engineering seismology on the level of accuracy and detail. In seismic microzoning resonance frequency of the upper part of section are determined on the basis of this method. Maps of oscillation amplification and result accuracy are constructed for each of the frequencies. The same method makes it possible to study standing wave field in buildings and constructions with high accuracy and detail, realizing diagnostics of their physical state on set of natural frequencies and form of self-oscillations, examined with high detail. The method of standing waves permits to estimate a seismic stability of structure on new accuracy level.

Structural and Predictive Properties of the Emotional Quotient Inventory Youth Version-Short Form (EQ-i:YV[S]).

Davis, Sarah K; Wigelsworth, Michael

2018-01-01

Emotional intelligence (EI) is a popular construct with concentrated areas of application in education and health contexts. There is a need for reliable and valid measurement of EI in young people, with brief yet sensitive measures of the construct preferable for use in time-limited settings. However, the proliferation of EI measures has often outpaced rigorous psychometric evaluation (Gignac, 2009 ). Using data from 849 adolescents (407 females, 422 males) aged 11 to 16 years (M age 13.4, SD = 1.2 years), this article systematically examines the structural and predictive properties of a frequently employed measure of adolescent trait EI-the Emotional Quotient Inventory Youth Version-Short Form (EQ-i:YV[S]); Bar-On & Parker, 2000 ). Although the intended multidimensional factor structure was recovered through confirmatory factor analysis, the statistical and conceptual coherency of the underlying model was inadequate. Using a multitrait-multimethod approach, the EQ-i:YV(S) was found to converge with other measures of EI; however, evidence for divergent validity (Big Five personality dimensions) was less robust. Predictive utility for adolescent mental health outcomes (depression, disruptive behavior) was also limited. Findings suggest that use of the EQ-i:YV(S) for predictive or evaluative purposes should be avoided until refinements to the scale are made.

Entanglement of Multi-qudit States Constructed by Linearly Independent Coherent States: Balanced Case

NASA Astrophysics Data System (ADS)

Najarbashi, G.; Mirzaei, S.

2016-03-01

Multi-mode entangled coherent states are important resources for linear optics quantum computation and teleportation. Here we introduce the generalized balanced N-mode coherent states which recast in the multi-qudit case. The necessary and sufficient condition for bi-separability of such balanced N-mode coherent states is found. We particularly focus on pure and mixed multi-qubit and multi-qutrit like states and examine the degree of bipartite as well as tripartite entanglement using the concurrence measure. Unlike the N-qubit case, it is shown that there are qutrit states violating monogamy inequality. Using parity, displacement operator and beam splitters, we will propose a scheme for generating balanced N-mode entangled coherent states for even number of terms in superposition.

Coherent Doppler lidar for automated space vehicle, rendezvous, station-keeping and capture

Dunkin, James A.

1991-01-01

Recent advances in eye-safe, short wavelength solid-state lasers offer real potential for the development of compact, reliable, light-weight, efficient coherent lidar. Laser diode pumping of these devices has been demonstrated, thereby eliminating the need for flash lamp pumping, which has been a major drawback to the use of these lasers in space based applications. Also these lasers now have the frequency stability required to make them useful in coherent lidar, which offers all of the advantages of non-coherent lidar, but with the additional advantage that direct determination of target velocity is possible by measurement of the Doppler shift. By combining the Doppler velocity measurement capability with the inherent high angular resolution and range accuracy of lidar it is possible to construct Doppler images of targets for target motion assessment. A coherent lidar based on a Tm,Ho:YAG 2-micrometer wavelength laser was constructed and successfully field tested on atmospheric targets in 1990. This lidar incorporated an all solid state (laser diode pumped) master oscillator, in conjunction with a flash lamp pumped slave oscillator. Solid-state laser technology is rapidly advancing, and with the advent of high efficiency, high power, semiconductor laser diodes as pump sources, all-solid-state, coherent lidars are a real possibility in the near future. MSFC currently has a feasibility demonstration effort under way which will involve component testing, and preliminary design of an all-solid-state, coherent lidar for automatic rendezvous, and capture. This two year effort, funded by the Director's Discretionary Fund is due for completion in 1992.

Gamma-band activity in the human superior temporal sulcus during mentalizing from nonverbal social cues.

Cohen, Michael X; David, Nicole; Vogeley, Kai; Elger, Christian E

2009-01-01

The posterior superior temporal sulcus (pSTS) is a key structure for our ability to infer others' mental states based on social cues including facial expressions, body posture, and gestures ("mentalizing"), but the neural mechanisms of this ability remain largely unknown. We recorded electrocorticogram directly from the pSTS in humans to show that enhanced neural oscillations in the gamma frequency range (35-55 Hz) accompany mentalizing. One patient with a lesion in pSTS was tested behaviorally on this task; he was unable to infer a virtual character's preferences from nonverbal social cues. Enhanced coherent gamma oscillations in the patients with intact pSTS may reflect a process by which social signals are bound into a unified representation to support mentalizing. This may be relevant for other social cognitive processes, as well as to the study of autism spectrum disorders, for which both mentalizing deficits and abnormal gamma activity have been reported.

The taming of the shrew: batterers' constructions of their wives' narratives.

PubMed

Borochowitz, Dalit Yassour

2008-10-01

Constructing a life story is a need shared by all humans to give their lives meaning and coherence. This article explores some of the narrative devices that batterers use to achieve a sense of coherence when telling their stories and justifying their violent behavior. A central theme that emerged from these stories centered on the men's perception of their wives as the embodiment of their own emotions and inner world. Two narrative strategies were identified in this context: (a) The construction of a "couple narrative" that focused on an idealized marital relationship rather than "allowing" the wife her story and (b) constructing a story around the theme of "she's not the same woman I married," which portrays the wife as "a shrew" and the violence as an attempt to discipline her. The stories of 18 batterers were used for this analysis, and two narratives were used to illustrate these strategies.

Mental health nurses' attitudes, behaviour, experience and knowledge regarding adults with a diagnosis of borderline personality disorder: systematic, integrative literature review.

To establish whether mental health nurses responses to people with borderline personality disorder are problematic and, if so, to inform solutions to support change. There is some evidence that people diagnosed with borderline personality disorder are unpopular among mental health nurses who respond to them in ways which could be counter-therapeutic. Interventions to improve nurses' attitudes have had limited success. Systematic, integrative literature review. Computerised databases were searched from inception to April 2015 for papers describing primary research focused on mental health nurses' attitudes, behaviour, experience, and knowledge regarding adults diagnosed with borderline personality disorder. Analysis of qualitative studies employed metasynthesis; analysis of quantitative studies was informed by the theory of planned behaviour. Forty studies were included. Only one used direct observation of clinical practice. Nurses' knowledge and experiences vary widely. They find the group very challenging to work with, report having many training needs, and, objectively, their attitudes are poorer than other professionals' and poorer than towards other diagnostic groups. Nurses say they need a coherent therapeutic framework to guide their practice, and their experience of caregiving seems improved where this exists. Mental health nurses' responses to people with borderline personality disorder are sometimes counter-therapeutic. As interventions to change them have had limited success there is a need for fresh thinking. Observational research to better understand the link between attitudes and clinical practice is required. Evidence-based education about borderline personality disorder is necessary, but developing nurses to lead in the design, implementation and teaching of coherent therapeutic frameworks may have greater benefits. There should be greater focus on development and implementation of a team-wide approach, with nurses as equal partners, when working with patients with borderline personality disorder. © 2016 John Wiley & Sons Ltd.

bvFTD patients display an impairment in the attribution of cognitive and affective states to others, reflecting GM atrophy in brain regions associated with social cognition, such as amygdala, superior temporal cortex and posterior insula. Distinctive patterns of abnormal brain functioning at rest have been reported in bvFTD, but their relationship with defective attribution of affective states has not been investigated. To investigate the relationship among resting-state brain activity, gray matter (GM) atrophy and the attribution of mental states in the behavioral variant of fronto-temporal degeneration (bvFTD). We compared 12 bvFTD patients with 30 age- and education-matched healthy controls on a) performance in a task requiring the attribution of affective vs. cognitive mental states; b) metrics of resting-state activity in known functional networks; and c) the relationship between task-performances and resting-state metrics. In addition, we assessed a connection between abnormal resting-state metrics and GM atrophy. Compared with controls, bvFTD patients showed a reduction of intra-network coherent activity in several components, as well as decreased strength of activation in networks related to attentional processing. Anomalous resting-state activity involved networks which also displayed a significant reduction of GM density. In patients, compared with controls, higher affective mentalizing performance correlated with stronger functional connectivity between medial prefrontal sectors of the default-mode and attentional/performance monitoring networks, as well as with increased coherent activity in components of the executive, sensorimotor and fronto-limbic networks. Some of the observed effects may reflect specific compensatory mechanisms for the atrophic changes involving regions in charge of affective mentalizing. The analysis of specific resting-state networks thus highlights an intermediate level of analysis between abnormal brain structure and impaired behavioral performance in bvFTD, reflecting both dysfunction and compensation mechanisms.

The Role of Task Understanding on Younger and Older Adults' Performance.

Frank, David J; Touron, Dayna R

2016-12-16

Age-related performance decrements have been linked to inferior strategic choices. Strategy selection models argue that accurate task representations are necessary for choosing appropriate strategies. But no studies to date have compared task representations in younger and older adults. Metacognition research suggests age-related deficits in updating and utilizing strategy knowledge, but other research suggests age-related sparing when information can be consolidated into a coherent mental model. Study 1 validated the use of concept mapping as a tool for measuring task representation accuracy. Study 2 measured task representations before and after a complex strategic task to test for age-related decrements in task representation formation and updating. Task representation accuracy and task performance were equivalent across age groups. Better task representations were related to better performance. However, task representation scores remained fairly stable over the task with minimal evidence of updating. Our findings mirror those in the mental model literature suggesting age-related sparing of strategy use when information can be integrated into a coherent mental model. Future research should manipulate the presence of a unifying context to better evaluate this hypothesis. © The Author 2016.

Does Mindfulness Improve After Heart Coherence Training in Patients With Chronic Musculoskeletal Pain and Healthy Subjects? A Pilot Study.

2015-07-01

Mindfulness and heart coherence training (HCT) training are applied increasingly in the treatment of patients with chronic musculoskeletal pain (CMP). Questionnaires have been developed to assess changes in mindfulness but no gold standard is available. Explore the relationship between changes in mindfulness scores and changes in heart coherence after 3 sessions of HCT in patients with CMP and in healthy subjects. Ten patients with CMP and 15 healthy subjects were trained in self-regulation with the use of HCT following a standardized stress relief program developed by the HeartMath Institute. A heart coherence-score (HC-score) was constructed with scores ranging from 0-100 with higher scores reflecting more heart rate variability (HRV) coherency. Change scores, Spearman correlation coefficients, and Wilcoxon Signed Rank test were calculated to test relationships and differences between HC-score, the Mindfulness Attention and Awareness Scale (MAAS) and Five Facet Mindfulness Questionnaire (FFMQ). A new questionnaire was constructed to explore on which mindfulness-related domains patients with CMP report changes after HCT. Increases were present on HC-score in healthy subjects (P<.01) and in patients (P<.01) between baseline and follow-up. Effect sizes on change on the MAAS and FFMQ were low. Weak (r<0.25) and non-significant correlations were observed in change scores between HC-score and MAAS or FFMQ. Patients reported significant favorable differences on 6 mindfulness related domains in the new questionnaire: breathing rhythm, physical awareness, positive or negative emotions, recognition of stressful situations, thoughts, and tendency to actively self-regulate. In this pilot study, mindfulness as assessed by the MAAS and FFMQ does not appear to improve after HCT. HRV coherency, MAAS, and FFMQ measure different constructs and are weakly related. It is of great importance to choose and develop valid measures that reflect patients' states of mindfulness. Content and face validity of measures of mindfulness may be considered in the light of performance-based measures.

Beyond attributions: Understanding public stigma of mental illness with the common sense model.

2014-03-01

The present study applied the common sense model (i.e., cause, controllability, timeline, consequences, and illness coherence) to understand public attitudes toward mental illness and help-seeking intention and to examine the mediating role of perceived controllability between causal attributions with public attitudes and help seeking. Based on a randomized household sample of 941 Chinese community adults in Hong Kong, results of the structural equation modeling demonstrated that people who endorsed cultural lay beliefs tended to perceive the course of mental illness as less controllable, whereas those with psychosocial attributions see its course as more controllable. The more people perceived the course of mental illness as less controllable, more chronic, and incomprehensible, the lower was their acceptance and the greater was mental illness stigma. Furthermore, those who perceived mental illness with dire consequences were more likely to feel greater stigma and social distance. Conversely, when people were more accepting, they were more likely to seek help for psychological services and felt a shorter social distance. The common sense model provides a multidimensional framework in understanding public's mental illness perceptions and stigma. Not only should biopsychosocial determinants of mental illness be advocated to the public, cultural myths toward mental illness must be debunked.

The coherence effect: Blending cold and hot cognitions.

PubMed

Simon, Dan; Stenstrom, Douglas M; Read, Stephen J

2015-09-01

Previous research has shown that making complex judgments and decisions entails a mental reconstruction of the task in a way that increases the state of coherence between the emerging conclusion and its underlying attributes: The attributes that support the conclusion grow stronger, whereas the attributes that support the losing option weaken. This coherence effect is understood to occur bidirectionally, in that conclusions follow from the decision-maker's evaluation of the attributes, while the evaluations of the attributes shift to cohere with the emerging conclusion. The current studies were designed to extend the coherence effect to encompass cognitions that could be considered "hot," such as valence evaluations, motivation toward outcomes of events, liking and disliking of actors, and emotions toward actors. Study 1 found that evaluations of a complex social relationship were accompanied not only by supportive interpretations of the ambiguous facts, but also by concordant hot cognitions. Studies 2 through 4 included manipulations to demonstrate the spreading of coherence from cold to hot cognitions and in the opposite direction. We observed these effects following a manipulation of the facts (Study 2), a manipulation of participants' emotions toward the actor (Study 3), and a manipulation of participants' motivation toward the outcome of the case (Study 4). These results support the proposition that complex judgments and decisions are performed by coherence-based reasoning: a holistic, connectionist process that maximizes coherence among and between the myriad of factors involved in the tasks and the hot cognitive reactions to them.

Increased awareness of the importance of mental health for global health has led to a number of new initiatives, including influential policy instruments issued by the World Health Organization (WHO) and the United Nations (UN). This policy brief describes two WHO instruments, the Mental Health Action Plan for 2013-2020 (World Health Organization, 2013) and the Mental Health Atlas (World Health Organization, 2015), and presents a comparative analysis with the Sustainable Development Goals (SDGs) of the UN's 2030 Agenda for Sustainable Development (United Nations, 2015). The WHO's Action Plan calls for several specific objectives and targets, with a focus on improving global mental health governance and service coverage. In contrast, the UN's Sustainable Development Goals include only one goal specific to mental health, with a single indicator tracking suicide mortality rates. The discrepancy between the WHO and UN frameworks suggests a need for increased policy coherence. Improved global health governance can provide the basis for ensuring and accelerating progress in global mental health. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

In Defense of Theory.

Jackendoff, Ray

2017-03-01

Formal theories of mental representation have receded from the importance they had in the early days of cognitive science. I argue that such theories are crucial in any mental domain, not just for their own sake, but to guide experimental inquiry, as well as to integrate the domain into the mind as a whole. To illustrate the criteria of adequacy for theories of mental representation, I compare two theoretical approaches to language: classical generative grammar (Chomsky, 1965, 1981, 1995) and the parallel architecture (Jackendoff, 1997, 2002). The grounds for comparison include (a) the internal coherence of the theory across phonology, syntax, and semantics; (b) the relation of language to other mental faculties; (c) the relationship between grammar and lexicon; (d) relevance to theories of language processing; and (e) the possibility of languages with little or no syntax.

2017-04-01

Mathematics proof is one of the characteristics of advanced mathematics thinking, and proof plays an important role in learning the abstract algebra included group theory. The depth and complexity of individual’s understanding of a concept depend on his/her ability to establish connections among the mental structure that constitute it. One of the cognitive styles is field dependent/independent. Field independent (FI) and field dependent (FD) learners have different characteristics. Our research question is (1)How is the proposed refinement of preliminary genetic decomposition of group that is designed with a preliminary study of the learning with APOS works; (2) What understanding about group that is generated by student (Field Independent, Field Neutral, and Field Dependent) when learning through designed material. This study was a descriptive qualitative. The participants of this study were nine (9) undergraduate students who were taking Introduction of Algebraic Structure 1, which included group, in the even semester of academic year 2015/2016 at Universitas Negeri Semarang. Each of type of cognitive styles consisted of 3 participants. There were two instruments used to gather data: written examination in the course and a set of the interview. The FD and FN participants generated Action for a binary operation. The FI participant generated Action and Process for a binary operation. The FD, FN and FI participants generated Action, Process, Object, and Scheme for the set. The FD and FN participant did not generate mental structure for axiom. The FI participant generated Scheme for axiom. The FD, FN and FI participants tend to have no Coherence of Scheme of the group. Not all mental structure on the refinement of the preliminary genetic decomposition can be constructed by participants so well that there are still obstacles in the process of proving.

Whilst striving to create a balanced and healthy life, individuals experience challenges across their life span. Spirituality can contribute to mental health and well-being, as can cultural constructs. In South Africa, apartheid categories are still vivid, which affect spiritual, cultural and racial mental constructs and impact on the mental health of individuals across cultural groups. This article focuses on the long-term development of spiritual and cultural concepts within a selected individual in Cape Town, South Africa, during 11 years of field work. It also explores the impact of spirituality and culture on the researcher-researched relationship. A mixed-method approach was used, including various qualitative methods of data collection as well as content analysis to analyse the data and intersubjective validation to interpret them. Findings show a strong intrapersonal interlinkage of spirituality, culture and mental health and the researcher-researched relationship having a strong impact on spiritual, cultural and mental health constructions. We are not human beings having a spiritual experience. We are spiritual beings having a human experience. (Pierre Teilhard de Chardin, 1976).

Factors promoting sense of coherence among university students in urban areas of Japan: individual-level social capital, self-efficacy, and mental health.

PubMed

Mato, Mie; Tsukasaki, Keiko

2017-04-01

Sense of coherence (SOC) is a concept that helps to explain the relation between personal intentionality as psychosocial factors and health-related behaviors. Thus, it is essential to enhance SOC when encouraging a healthy lifestyle. However, the factors that promote SOC have not been fully investigated among university students. The objective of this study was to clarify the general resistance resources (GRRs) that may promote the development of the SOC among university students. Therefore, we examined the relationship between SOC and social capital (SC), self-efficacy, and mental health. Participants included 443 students from nine academic departments at eight universities in the Kanto or Kinki metropolitan areas of Japan. Participants completed an anonymous questionnaire. Individual-level cognitive and structural SC, generalized self-efficacy, mental health inventory (from SF-36v2), and SOC were measured. Confirmatory factor analysis using structural equation modeling was conducted to verify the factor structure of the SOC-13 scale. Stepwise multiple regression analysis and two-way layout analysis of variance were performed with SOC as the dependent variable. The factor structure of SOC indicated the optimal model fit in the second-order three-factor model of the 12 items. SOC was predicted by five variables: age, cognitive SC, structural SC, mental health, and self-efficacy. For students from urban areas, SOC was predicted by the interaction between cognitive and structural SC. SOC was significantly related to cognitive SC, structural SC, and self-efficacy as well as mental health in university students from urban areas. Furthermore, the combination of higher-level cognitive SC and higher-level structural SC exerted an inhibitory influence on SOC among students who previously and currently live in urban areas. Therefore, the findings indicated that both cognitive and structural SC as well as self-efficacy may act as GRRs that promote the development of SOC, and similarly, good mental health may promote a strong SOC.

Non-Gaussian statistics and optical rogue waves in stimulated Raman scattering.

We explore theoretically and numerically optical rogue wave formation in stimulated Raman scattering inside a hydrogen filled hollow core photonic crystal fiber. We assume a weak noisy Stokes pulse input and explicitly construct the input Stokes pulse ensemble using the coherent mode representation of optical coherence theory, thereby providing a link between optical coherence and rogue wave theories. We show that the Stokes pulse peak power probability distribution function (PDF) acquires a long tail in the limit of nearly incoherent input Stokes pulses. We demonstrate a clear link between the PDF tail magnitude and the source coherence time. Thus, the latter can serve as a convenient parameter to control the former. We explain our findings qualitatively using the concepts of statistical granularity and global degree of coherence.

Sense of coherence and its association with exposure to traumatic events, posttraumatic stress disorder, and depression in eastern Democratic Republic of Congo.

The Democratic Republic of Congo is the scene of some of the worst atrocities in recent history. However, in the face of traumatic experience, only a minority of people develops symptoms that impair their functioning. The sense of coherence proposed by Antonovsky (1987) is a theoretical construct reflecting an individual's overall wellbeing and ability to cope with stress. This study explores the relationships between sense of coherence, exposure to traumatic events, symptoms of posttraumatic stress disorder (PTSD), and depression. Results suggest an association between a high sense of coherence and high education levels, high income, and positive social relationships. Furthermore, the study found that sense of coherence is inversely correlated with cumulative exposure to violence and symptoms of PTSD and depression.

The Cultural Construction of Mental Illness in Prison: A Perfect Storm of Pathology

PubMed Central

2013-01-01

Large numbers of individuals in U.S. prisons meet DSM criteria for severe psychiatric disorder. These individuals also have co-occurring personality and substance abuse disorders, medical conditions, and histories of exposure to social pathologies. Based on nine months of ethnographic fieldwork in a U.S. prison, focusing on staff narratives, I utilize interpretivist and constructivist perspectives to analyze how mental health clinicians construct psychiatric disorder among inmates. Discrete categorization of disorders may be confounded by the clinical co-morbidities of inmates and the prison context. Incarcerated individuals’ responses to the institutional context substantially inform mental health staffs’ illness construction and the prison itself is identified as an etiological agent for disordered behaviors. In addition, diagnostic processes are found to be indeterminate, contested, and shaped by interactions with staff. Analysis of illness construction reveals that what is at stake for clinicians is not only provision of appropriate treatment, but also mandates for the safety and security of the institution. Enmeshed in these mandates, prison mental health becomes a particular local form of psychiatric knowledge. This paper contributes to anthropological approaches to mental disorder by demonstrating how local contexts mediate psychiatric knowledge and contribute to the limited ethnographic record of prisons.

In contrast to the resource theory of coherence and asymmetry, we construct a natural measure of quantum coherence inspired from optical coherence theory while the group theoretical approach is employed to quantify the asymmetry of quantum states. Besides their simple structures and explicit physical meanings, we observe that these quantities are intimately related to the purity (or linear entropy) of the corresponding quantum states. Remarkably, we demonstrate that the proposed coherence quantifier is not only a measure of mixedness, but also an intrinsic (basis-independent) quantification of quantum coherence contained in quantum states, which can also be viewed as a normalized version of Brukner-Zeilinger invariant information. In our context, the asymmetry of N-qubit quantum systems is considered under local independent and collective transformations. In- triguingly, it is illustrated that the collective effect has a significant impact on the asymmetry measure, and quantum correlation between subsystems plays a non-negligible role in this circumstance.

We argue that infant meaning-making processes are a central mechanism governing both typical and pathological outcomes. Infants, as open dynamic systems, must constantly garner information to increase their complexity and coherence. They fulfill this demand by making nonverbal "meaning"--affects, movements, representations--about themselves in…

Detecting Pilot's Engagement Using fNIRS Connectivity Features in an Automated vs. Manual Landing Scenario

PubMed Central

Verdière, Kevin J.; Roy, Raphaëlle N.; Dehais, Frédéric

2018-01-01

Monitoring pilot's mental states is a relevant approach to mitigate human error and enhance human machine interaction. A promising brain imaging technique to perform such a continuous measure of human mental state under ecological settings is Functional Near-InfraRed Spectroscopy (fNIRS). However, to our knowledge no study has yet assessed the potential of fNIRS connectivity metrics as long as passive Brain Computer Interfaces (BCI) are concerned. Therefore, we designed an experimental scenario in a realistic simulator in which 12 pilots had to perform landings under two contrasted levels of engagement (manual vs. automated). The collected data were used to benchmark the performance of classical oxygenation features (i.e., Average, Peak, Variance, Skewness, Kurtosis, Area Under the Curve, and Slope) and connectivity features (i.e., Covariance, Pearson's, and Spearman's Correlation, Spectral Coherence, and Wavelet Coherence) to discriminate these two landing conditions. Classification performance was obtained by using a shrinkage Linear Discriminant Analysis (sLDA) and a stratified cross validation using each feature alone or by combining them. Our findings disclosed that the connectivity features performed significantly better than the classical concentration metrics with a higher accuracy for the wavelet coherence (average: 65.3/59.9 %, min: 45.3/45.0, max: 80.5/74.7 computed for HbO/HbR signals respectively). A maximum classification performance was obtained by combining the area under the curve with the wavelet coherence (average: 66.9/61.6 %, min: 57.3/44.8, max: 80.0/81.3 computed for HbO/HbR signals respectively). In a general manner all connectivity measures allowed an efficient classification when computed over HbO signals. Those promising results provide methodological cues for further implementation of fNIRS-based passive BCIs. PMID:29422841

Protecting quantum information in superconducting circuits

NASA Astrophysics Data System (ADS)

Devoret, Michel

Can we prolong the coherence of a two-state manifold in a complex quantum system beyond the coherence of its longest-lived component? This question is the starting point in the construction of a scalable quantum computer. It translates in the search for processes that operate as some sort of Maxwell's demon and reliably correct the errors resulting from the coupling between qubits and their environment. The presentation will review recent experiments that test the dynamical protection by Josephson circuits of a logical qubit memory based on superpositions of particular coherent states of a superconducting resonator.

Coherence measurement with digital micromirror device.

Partanen, Henri; Turunen, Jari; Tervo, Jani

2014-02-15

We measure the complex-valued spatial coherence function of a multimode broad-area laser diode using Young's classical double slit experiment realized with a digital micromirror device. We use this data to construct the coherent modes of the beam and to simulate its propagation before and after the measurement plane. When comparing the results to directly measured intensity profiles, we find excellent correspondence to the extent that even small details of the beam can be predicted. We also consider the number of measurement points required to model the beam with sufficient accuracy.

Coherent controlization using superconducting qubits

Friis, Nicolai; Melnikov, Alexey A.; Kirchmair, Gerhard; Briegel, Hans J.

2015-01-01

Coherent controlization, i.e., coherent conditioning of arbitrary single- or multi-qubit operations on the state of one or more control qubits, is an important ingredient for the flexible implementation of many algorithms in quantum computation. This is of particular significance when certain subroutines are changing over time or when they are frequently modified, such as in decision-making algorithms for learning agents. We propose a scheme to realize coherent controlization for any number of superconducting qubits coupled to a microwave resonator. For two and three qubits, we present an explicit construction that is of high relevance for quantum learning agents. We demonstrate the feasibility of our proposal, taking into account loss, dephasing, and the cavity self-Kerr effect. PMID:26667893

Mental health literacy as theory: current challenges and future directions.

PubMed

Spiker, Douglas A; Hammer, Joseph H

2018-02-13

Mental health literacy (MHL) is one increasingly researched factor thought to influence mental health behaviors. Researchers have argued for expanding the definition of MHL to include additional constructs, but no consensus has yet been reached on what constructs should be included as part of MHL. The purpose of this paper is to (i) elucidate how the expansion of the MHL construct has impeded the growth of MHL research and (ii) through the lens of construct and theory development, highlight how these challenges might be remedied. An inclusive search of the literature was undertaken to identify MHL studies. The principles of construct and theory development guided a critical analysis of MHL. The review of the literature found that MHL violates many principles of what constitutes an acceptable construct definition. To address these concerns, we proposed conceptualizing MHL as a theory and recommended principles of theory development that should be taken into consideration. A theory of MHL can guide future researchers to clearly delineate important constructs and their interrelationships. For practitioners, a theory of MHL can help inform how to improve MHL at both the individual and community level.

2010-05-01

We explored mental toughness in soccer using a triangulation of data capture involving players (n = 6), coaches (n = 4), and parents (n = 5). Semi-structured interviews, based on a personal construct psychology (Kelly, 1955/1991) framework, were conducted to elicit participants' perspectives on the key characteristics and their contrasts, situations demanding mental toughness, and the behaviours displayed and cognitions employed by mentally tough soccer players. The results from the research provided further evidence that mental toughness is conceptually distinct from other psychological constructs such as hardiness. The findings also supported Gucciardi, Gordon, and Dimmock's (2009) process model of mental toughness. A winning mentality and desire was identified as a key attribute of mentally tough soccer players in addition to other previously reported qualities such as self-belief, physical toughness, work ethic/motivation, and resilience. Key cognitions reported by mentally tough soccer players enabled them to remain focused and competitive during training and matches and highlighted the adoption of several forms of self-talk in dealing with challenging situations. Minor revisions to Gucciardi and colleagues' definition of mental toughness are proposed.

Doppler optical coherence microscopy and tomography applied to inner ear mechanics

Page, Scott; Freeman, Dennis M.; Department of Electrical Engineering and Computer Science, Massachusetts Institute of Technology, Cambridge, Massachusetts

While it is clear that cochlear traveling waves underlie the extraordinary sensitivity, frequency selectivity, and dynamic range of mammalian hearing, the underlying micromechanical mechanisms remain unresolved. Recent advances in low coherence measurement techniques show promise over traditional laser Doppler vibrometry and video microscopy, which are limited by low reflectivities of cochlear structures and restricted optical access. Doppler optical coherence tomography (DOCT) and Doppler optical coherence microscopy (DOCM) both utilize a broadband source to limit constructive interference of scattered light to a small axial depth called a coherence gate. The coherence gate can be swept axially to image and measure sub-nanometermore » motions of cochlear structures throughout the cochlear partition. The coherence gate of DOCT is generally narrower than the confocal gate of the focusing optics, enabling increased axial resolution (typically 15 μm) within optical sections of the cochlear partition. DOCM, frequently implemented in the time domain, centers the coherence gate on the focal plane, achieving enhanced lateral and axial resolution when the confocal gate is narrower than the coherence gate. We compare these two complementary systems and demonstrate their utility in studying cellular and micromechanical mechanisms involved in mammalian hearing.« less

Talent development: linking the stakeholders to the process.

The three stakeholders (coaches, parents and the National Governing Body) in Talent Identification and Development (TID) are important factors in athlete development. How each of them perceive the key constructs of Talent Identification and Development (i.e. sport specialisation and selection, practice, athlete development, junior and adult success, and the role of the stakeholders), and the coherence of that understanding is not well understood. This study focuses on junior performance tennis and investigates the perceptions of coaches, parents and sports organisations (a National Governing Body) of the five key constructs of Talent Identification and Development. We were interested in examining (a) the extent to which stakeholder perceptions relate to research, (b) the coherence of each stakeholder's perceptions and (c) the extent to which there is coherence between what stakeholders understand each other thinks. Seventy-five coaches, parents, and National Governing Body staff completed a questionnaire that asked participants to rate their degree of agreement/disagreement with researched 'principles' of Talent Identification and Development. The results suggest that stakeholders do not strongly agree with the research supporting principles of Talent Identification and Development. Furthermore, a significant lack of coherence of stakeholder perceptions was evident. This lack of coherence was also evident in each group's understanding of what the other stakeholders believed. The impact of these results on the Talent Identification and Development process is discussed.

Culture and the social construction of gender: mapping the intersection with mental health.

PubMed

Andermann, Lisa

2010-01-01

The social construction of gender is an important concept for better understanding the determinants of mental health in women and men. Going beyond physical and physiological differences and the traditional biomedical approach, interdisciplinary study of the complex factors related to culture and society, power and politics is necessary to be able to find solutions to situations of disparity in mental health, related to both prevalence of disorders, availability and response to treatment. Gender inequality continues to be a source of suffering for many women around the world, and this can lead to adverse mental health outcomes. This review focuses on developments in the literature on culture, gender and mental health over the past decade, focusing on themes around the social construction of gender, mental health and the media, a look at cultural competence through a gender lens, gender and the body, providing some examples of the intersection between mental health and gender in low-income countries as well as the more developed world, and the impact of migration and resettlement on mental health. At the clinical level, using a bio-psycho-social-spiritual model that can integrate and negotiate between both traditional and biomedical perspectives is necessary, combined with use of a cultural formulation that takes gender identity into account. Research involving both qualitative and quantitative perspectives, and in many cases an ethnographic framework, is essential in tackling these global issues.

New class of generalized photon-added coherent states and some of their non-classical properties

In this paper, we construct a new class of generalized photon added coherent states (GPACSs), |z,m{{\\rangle }_{r}} by excitations on a newly introduced family of generalized coherent states (GCSs) |z{{\\rangle }_{r}} (A Dehghani and B Mojaveri 2012 J. Phys. A: Math. Theor. 45 095304), obtained via generalized hypergeometric type displacement operators acting on the vacuum state of the simple harmonic oscillator. We show that these states realize resolution of the identity property through positive definite measures on the complex plane. Meanwhile, we demonstrate that the introduced states can also be interpreted as nonlinear coherent states (NLCSs), with a spacial nonlinearity function. Finally, some of their non-classical features as well as their quantum statistical properties are compared with Agarwal's photon-added coherent states (PACSs), \\left| z,m \\right\\rangle .

Constructing GCS in a many-dimensional case, we meet technical complications that make the consideration nontrivial and instructive. The GCS of the system under consideration are constructed. We study the properties of this GCS such as completeness relations, minimization of uncertainty relations, and so on. We point out which family of the obtained GCS of a charged particle in a magnetic field is related to the CS constructed first by Malkin and Man'ko. We obtain conditions under which some of the GCS can be considered as semiclassical states (SS).

Schleim, Stephan

2018-01-01

Increasing research efforts try to identify biological markers in order to support or eventually replace current practices of diagnosing mental disorders. Inasmuch as these disorders refer to subjective mental states, such efforts amount to their objectification. This gives rise to conceptual as well as empirical challenges: What kind of things are mental disorders? And how to deal with situations where subjective reports, clinical decisions, and brain scans contradict each other? The present paper starts out with a discussion of recent efforts to objectify beauty. Such attempts to quantify and localize psychological constructs in the brain are compared to earlier examples from the history of psychology. The paper then discusses personal and social implications of the objectification of subjective mental states, including mental disorders. The construct of Major Depressive Disorder, one of the most prevalent mental disorders, is then analyzed in more detail. It turns out that this is a very complex construct probably associated with highly heterogeneous actual instances of the disorder. It is then shown that it is unlikely to replace these symptoms' descriptions with patterns of brain activations, at least in the near future, given these patterns' empirical lack of specificity. The paper then discusses which of the disorder's core symptoms are more or less amenable to behavioral or neuroscientific investigation and analyses whether the heterophenomenological method can solve the problem. The conclusion is that the disorder construct is neither entirely subjective, nor completely objectifiable, and that clinical experts do well by continuing to take a pragmatical stance.

[Electroencephalographic characteristic of cognitive-specific alerting attention in verbal learning--III: Localized characteristics of EEG spatial synchronization].

Electroencephalograms (EEG) were recorder in 19 standard derivations in 88 healthy subjects, while they were in the states: rest with eyes open; memorization (learning) of verbal bilingual semantic pairs (Latin and Russian languages); the retrieval of the rote information from memory (control). We compared estimates of EEG coherence in these states for the frequency bands theta (4-7 Hz), alpha-1 (7-10 Hz), alpha-2 (10-13 Hz), beta-1 (13-18 Hz), beta-2 (18-30 Hz), gamma (30-40 Hz). When compared with the rest most strongly expressed: for memorization a decrease of coherence in the pairs of derivations from frontal and central areas of the cortex in the EEG frequency bands; for retrieval an increase of coherence in interhemispheric derivation pairs of pariental-occipital region in majority of the frequency bands. For the retrieval also increases of coherence in the beta2 and gamma bands, along with coherence decreases at low frequencies take place in pairs formed by derivations from the parieto-occipital region with derivations from the frontal and the central ones. Dynamics of EEG coherence in comparisons of memorization and retrieval from the rest and each are expressed significantly more in the interhemispheric and crosshemispheric pairs of derivations than in the intrahemispheric pairs. Revealed topographic specificity of the dynamics of EEG coherence by changing the states is considered in terms of ideas about cognitive-specific forms of sustained goal-directed mental attention.

Little is known about intergeneration effects on mental health in the families of survivors of political oppression of communist regime in Central and Eastern Europe. We aimed to explore post-traumatic stress in the second generation of the Lithuanian survivors of political violence, and analyze links between parental and adult offsprings' sense of coherence in the families exposed to political violence during the oppressive communist regime in Lithuania. A total of 110 matched pairs of communist regime political violence survivors (mean age = 73.22 years) and their adult offspring (mean age = 44.65 years) participated in this study. Life-time traumatic experiences and sense of coherence were measured in both parents and their offspring. Post-traumatic stress symptoms were assessed in the second generation of survivors. We found a high vulnerability in the second generation of the Lithuanian families of political violence survivors, with a 29% of probable PTSD in the second generation based on self-report measures. A significant positive correlation between parental and adult offsprings' sense of coherence was found. Post-traumatic stress symptoms were associated negatively with a sense of coherence in the second generation. Our study indicates the links between parental and the second generation's sense of coherence in the families of survivors of political violence. The study raises broader questions about the intergenerational aspects of resilience. Further studies are needed to explore the links between parental and child sense of coherence in other samples.

To assess Malaysian dentists' perceptions of their mental well-being. A self-administered questionnaire was developed based on a conceptual framework of mental health and well-being model. Two aspects were assessed, namely the physiological (two domains) and the psychological (six domains). Participants were asked to rate their experiences of the aforementioned aspects using a 5-point Likert scale ranging from all the time to never. The response rate was 81%. Most of the dentists (61.7%) perceived having positive mental well-being. Under the physiological aspect, most respondents reported that they were 'generally happy' (93.3%), but about 30% stated they were 'stressed physically and emotionally'. Of the six domains under the psychological aspect, positive well-being was observed in the 'sense of coherence' and 'behavioural stress' domains. Participants who were above 40 years old, married and had children reported having a more positive mental well-being when compared with their counterparts. Overall, most Malaysian dentists perceived having a positive mental well-being. It is crucial, however, to closely monitor and initiate early interventions for those with negative symptoms to ensure the safe practice of dentistry.

Although the theory of salutogenesis provides generic understanding of how coping may be created, this theoretical perspective has not been explored sufficiently within research among people suffering from mental health problems. The aim of this study is to investigate the effect of talk-therapy groups based on salutogenic treatment principles on coping with mental health problems. In an experimental design, the participants (residents in the community) were randomly allocated to a coping-enhancing experimental group (n=59) and a control group (n=47) receiving standard care. Coping was measured using the sense of coherence (SOC) questionnaire. Coping improved significantly in the experiment group (+6 points) compared with the control group (-2 points). The manageability component contributed most to this improvement. Talk-therapy groups based on salutogenic treatment principles improve coping among people with mental health problems. Talk-therapy groups based on salutogenic treatment principles may be helpful in increasing coping in the recovery process among people with mental health problems and seem to be applicable to people with various mental health problems.

Measuring neurophysiological signals in aircraft pilots and car drivers for the assessment of mental workload, fatigue and drowsiness.

This paper reviews published papers related to neurophysiological measurements (electroencephalography: EEG, electrooculography EOG; heart rate: HR) in pilots/drivers during their driving tasks. The aim is to summarise the main neurophysiological findings related to the measurements of pilot/driver's brain activity during drive performance and how particular aspects of this brain activity could be connected with the important concepts of "mental workload", "mental fatigue" or "situational awareness". Review of the literature suggests that exists a coherent sequence of changes for EEG, EOG and HR variables during the transition from normal drive, high mental workload and eventually mental fatigue and drowsiness. In particular, increased EEG power in theta band and a decrease in alpha band occurred in high mental workload. Successively, increased EEG power in theta as well as delta and alpha bands characterise the transition between mental workload and mental fatigue. Drowsiness is also characterised by increased blink rate and decreased HR values. The detection of such mental states is actually performed "offline" with accuracy around 90% but not online. A discussion on the possible future applications of findings provided by these neurophysiological measurements in order to improve the safety of the vehicles will be also presented.

2016-05-30

The current study aims to further evaluate the psychometric properties of the Maryland Assessment of Recovery in Serious Mental Illness (MARS), a relatively new instrument designed to assess personal recovery status in individuals with serious mental illness. Two hundred and fifty individuals with serious mental illness receiving outpatient mental health treatment completed a baseline assessment which included the MARS and measures to assess recovery-related constructs, clinical outcomes, and social and community functioning. The MARS demonstrated excellent internal consistency and test-retest reliability. Good construct validity was evidenced by strong positive relationships between the MARS and recovery-related constructs (e.g. hope, empowerment, self-efficacy, and personal agency) and a strong negative relationship with self-stigma. Divergent validity was demonstrated by weaker relationships with cognitive and social functioning. The confirmatory factor analysis did not confirm the unitary factor structure found in previous research. Given the equivocal result of the CFA, additional exploratory work is needed to determine if a more complex factor structure is present. This study provides addition support for the psychometric soundness of the MARS and subsequently, its potential use as a measure of personal recovery status in people with serious mental illness.

Patient's perception of their illness influences their healthcare decisions. The objectives of this study were to explore patient's own beliefs about their illness (Schizophrenia) and perceived social support, and its impact on their attitudes toward pharmacological treatment in Lahore, Pakistan. This study was conducted at Mayo Hospital Lahore from March to September 2016. Hundred individuals suffering from Schizophrenia completed four questionnaires; a socio-demographic questionnaire, the Illness Perception Questionnaire for Schizophrenia(IPQ-S), Drug attitude Inventory-10 (DAI) and Multidimensional Scale of Perceived Social Support (PSS). Stress, family problems, lack of friends & financial worries were endorsed strongly by patients as cause of their mental illness. Ambiguity regarding their mental illness duration and personal control was observed. Patients' perceived significant negative consequences, negative emotional response, as well as had poor understanding of their mental illness and treatment effectiveness. Statistically significant gender differences in treatment control and illness coherence subscales of IPQS were observed. Drug attitude inventory was positively correlated with Treatment control subscale (p < .01) and negatively correlated with Illness coherence subscale of IPQS (p < .05). The negative consequences subscale and perceived social support was negatively correlated (p < .01). Patient's perception about their own illness is predictor of their drug taking attitude and perceived social support. Study results should help to develop new interventions to correct inaccurate beliefs in patients with schizophrenia to improve illness outcome.

Students' understanding of primary and secondary protein structure: drawing secondary protein structure reveals student understanding better than simple recognition of structures.

PubMed

Harle, Marissa; Towns, Marcy H

2013-01-01

The interdisciplinary nature of biochemistry courses requires students to use both chemistry and biology knowledge to understand biochemical concepts. Research that has focused on external representations in biochemistry has uncovered student difficulties in comprehending and interpreting external representations in addition to a fragmented understanding of fundamental biochemistry concepts. This project focuses on students' understanding of primary and secondary protein structure and drawings (representations) of hydrogen-bonding in alpha helices and beta sheets. Analysis demonstrated that students can recognize and identify primary protein structure concepts when given a polypeptide. However, when asked to draw alpha helices and beta sheets and explain the role of hydrogen bonding their drawings students exhibited a fragmented understanding that lacked coherence. Faculty are encouraged to have students draw molecular level representations to make their mental models more explicit, complete, and coherent. This is in contrast to recognition and identification tasks, which do not adequately probe mental models and molecular level understanding. © 2013 by The International Union of Biochemistry and Molecular Biology.

Reading Comprehension in Children with ADHD: Cognitive Underpinnings of the Centrality Deficit

2012-01-01

We examined reading comprehension in children with ADHD by assessing their ability to build a coherent mental representation that allows them to recall central and peripheral information. We compared children with ADHD (mean age 9.78) to word reading-matched controls (mean age 9.89) on their ability to retell a passage. We found that even though children with ADHD recalled more central than peripheral information, they showed their greatest deficit, relative to controls, on central information – a centrality deficit (Miller & Keenan, 2009). We explored the cognitive underpinnings of this deficit using regressions to compare how well cognitive factors (working memory, inhibition, processing speed, and IQ) predicted the ability to recall central information, after controlling for word reading ability, and whether these cognitive factors interacted with ADHD symptoms. Working memory accounted for the most unique variance. Although previous evidence for reading comprehension difficulties in children with ADHD have been mixed, this study suggests that even when word reading ability is controlled, children with ADHD have difficulty building a coherent mental representation, and this difficulty is likely related to deficits in working memory.

This paper examines the ability of people who are blind to construct a mental map and perform orientation tasks in real space by using Nintendo Wii technologies to explore virtual environments. The participant explores new spaces through haptic and auditory feedback triggered by pointing or walking in the virtual environments and later constructs a mental map, which can be used to navigate in real space. The study included 10 participants who were congenitally or adventitiously blind, divided into experimental and control groups. The research was implemented by using virtual environments exploration and orientation tasks in real spaces, using both qualitative and quantitative methods in its methodology. The results show that the mode of exploration afforded to the experimental group is radically new in orientation and mobility training; as a result 60% of the experimental participants constructed mental maps that were based on map model, compared with only 30% of the control group participants. Using technology that enabled them to explore and to collect spatial information in a way that does not exist in real space influenced the ability of the experimental group to construct a mental map based on the map model. Implications for rehabilitation The virtual cane system for the first time enables people who are blind to explore and collect spatial information via the look-around mode in addition to the walk-around mode. People who are blind prefer to use look-around mode to explore new spaces, as opposed to the walking mode. Although the look-around mode requires users to establish a complex collecting and processing procedure for the spatial data, people who are blind using this mode are able to construct a mental map as a map model. For people who are blind (as for the sighted) construction of a mental map based on map model offers more flexibility in choosing a walking path in a real space, accounting for changes that occur in the space.

Cultural stereotypes of women from South Asian communities: mental health care professionals' explanations for patterns of suicide and depression.

PubMed

Burr, J

2002-09-01

Low rates of treated depression and high rates of suicide in women from some South Asian communities are evident in epidemiological studies in the UK. It is argued here that explanations for these apparent differences are likely to be located in stereotypes of repressive South Asian cultures. This small scale study, utilising focus groups and individual interviews, sought to explore the construction of cultural stereotypes within mental health discourse with specific reference to stereotypes of women from South Asian communities. Mental health carers from a UK inner city area of relatively high social deprivation were targeted. Focus groups were conducted with a range of mental health care professionals who worked in both inpatient and outpatient mental health care services. In addition, individual interviews were conducted with consultant psychiatrists and General Practitioners. Extensive reference is made in this paper to the content of focus groups and interviews and how health carer's knowledge about and experience of South Asian cultures and caring for women from these communities was contextualised. Mental health care professionals constructed cultural difference in terms of fixed and immutable categories which operated to inferiorise Britain's South Asian communities. It is argued that their knowledge is constructed upon stereotypes of western culture as superior to a construction of eastern cultures as repressive, patriarchal and inferior to a western cultural ideal. Ultimately, it is argued that these stereotypes become incorporated as 'fact' and have the potential to misdirect diagnosis and therefore, also misdirect treatment pathways.

Effect of inhibitory firing pattern on coherence resonance in random neural networks

NASA Astrophysics Data System (ADS)

Yu, Haitao; Zhang, Lianghao; Guo, Xinmeng; Wang, Jiang; Cao, Yibin; Liu, Jing

2018-01-01

The effect of inhibitory firing patterns on coherence resonance (CR) in random neuronal network is systematically studied. Spiking and bursting are two main types of firing pattern considered in this work. Numerical results show that, irrespective of the inhibitory firing patterns, the regularity of network is maximized by an optimal intensity of external noise, indicating the occurrence of coherence resonance. Moreover, the firing pattern of inhibitory neuron indeed has a significant influence on coherence resonance, but the efficacy is determined by network property. In the network with strong coupling strength but weak inhibition, bursting neurons largely increase the amplitude of resonance, while they can decrease the noise intensity that induced coherence resonance within the neural system of strong inhibition. Different temporal windows of inhibition induced by different inhibitory neurons may account for the above observations. The network structure also plays a constructive role in the coherence resonance. There exists an optimal network topology to maximize the regularity of the neural systems.

Discovering Coherent Structures Using Local Causal States

NASA Astrophysics Data System (ADS)

Rupe, Adam; Crutchfield, James P.; Kashinath, Karthik; Prabhat, Mr.

2017-11-01

Coherent structures were introduced in the study of fluid dynamics and were initially defined as regions characterized by high levels of coherent vorticity, i.e. regions where instantaneously space and phase correlated vorticity are high. In a more general spatiotemporal setting, coherent structures can be seen as localized broken symmetries which persist in time. Building off the computational mechanics framework, which integrates tools from computation and information theory to capture pattern and structure in nonlinear dynamical systems, we introduce a theory of coherent structures, in the more general sense. Central to computational mechanics is the causal equivalence relation, and a local spatiotemporal generalization of it is used to construct the local causal states, which are utilized to uncover a system's spatiotemporal symmetries. Coherent structures are then identified as persistent, localized deviations from these symmetries. We illustrate how novel patterns and structures can be discovered in cellular automata and outline the path from them to laminar, transitional and turbulent flows.

Models as Relational Categories

2017-11-01

Model-based learning (MBL) has an established position within science education. It has been found to enhance conceptual understanding and provide a way for engaging students in authentic scientific activity. Despite ample research, few studies have examined the cognitive processes regarding learning scientific concepts within MBL. On the other hand, recent research within cognitive science has examined the learning of so-called relational categories. Relational categories are categories whose membership is determined on the basis of the common relational structure. In this theoretical paper, I argue that viewing models as relational categories provides a well-motivated cognitive basis for MBL. I discuss the different roles of models and modeling within MBL (using ready-made models, constructive modeling, and generative modeling) and discern the related cognitive aspects brought forward by the reinterpretation of models as relational categories. I will argue that relational knowledge is vital in learning novel models and in the transfer of learning. Moreover, relational knowledge underlies the coherent, hierarchical knowledge of experts. Lastly, I will examine how the format of external representations may affect the learning of models and the relevant relations. The nature of the learning mechanisms underlying students' mental representations of models is an interesting open question to be examined. Furthermore, the ways in which the expert-like knowledge develops and how to best support it is in need of more research. The discussion and conceptualization of models as relational categories allows discerning students' mental representations of models in terms of evolving relational structures in greater detail than previously done.

Adolescent construction of mental illness: implication for engagement and treatment.

Understanding how adolescents perceive mental illness is important for clinicians wishing to improve engagement, and for the development of educational programmes and health-behaviour directed policies. The current research aimed to develop a preliminary model of how adolescents perceive mental illness and construct their understanding of mental health. Forty-six participants aged 11-18 from six schools in Birmingham, UK, took part in one of 12 group interviews. A thematic analysis highlighted a dual perception of mental illness. Adolescents discussed stereotypes and extreme examples of illness, but also displayed an insightful understanding of mental distress which had developed through participants' own experiences. Participants attempted to reconcile and negotiate these conflicting perceptions by creating distinctions between concepts of 'craziness' and 'normality', and reported experiencing negative emotions relating to both perceptions of illness. The findings suggest that once media stereotypes have been acknowledged, adolescents demonstrate a relatively sophisticated understanding of mental illness, although one which differed at times from the diagnostic medical model of mental illness. Focusing on individual symptoms, prevalence rates and prior contact adolescents have had with individuals with mental illnesses provides a framework to discuss mental health and ill-health with adolescents.

Digital game-based learning (DGBL) makes use of the entertaining power of digital games for educational purposes. Effectiveness assessment of DGBL programs has been underexplored and no attempt has been made to simultaneously model both important components of DGBL: learning attainment (ie, educational purposes of DGBL) and engagement of users (ie, entertaining power of DGBL) in evaluating program effectiveness. This study aimed to describe and evaluate an Internet-based DGBL program, Professor Gooley and the Flame of Mind, which promotes mental health to adolescents in a positive youth development approach. In particular, we investigated whether user engagement in the DGBL program could enhance their attainment on each of the learning constructs per DGBL module and subsequently enhance their mental health as measured by psychological well-being. Users were assessed on their attainment on each learning construct, psychological well-being, and engagement in each of the modules. One structural equation model was constructed for each DGBL module to model the effect of users' engagement and attainment on the learning construct on their psychological well-being. Of the 498 secondary school students that registered and participated from the first module of the DGBL program, 192 completed all 8 modules of the program. Results from structural equation modeling suggested that a higher extent of engagement in the program activities facilitated users' attainment on the learning constructs on most of the modules and in turn enhanced their psychological well-being after controlling for users' initial psychological well-being and initial attainment on the constructs. This study provided evidence that Internet intervention for mental health, implemented with the technologies and digital innovations of DGBL, could enhance youth mental health. Structural equation modeling is a promising approach in evaluating the effectiveness of DGBL programs.

Dynamic analysis for mental sweating of a group of eccrin sweat glands on a human fingertip by optical coherence tomography

2011-05-01

OCT is highly potential for in vivo observation of human sweating dynamics which affects activity of the sympathetic nerve. In this paper, we demonstrate dynamic OCT analysis of mental sweating of a group of eccrin sweat glands. The sweating dynamics is tracked simultaneously for nineteen sweat glands by time-sequential piled-up en-face OCT images with the frame spacing of 3.3 sec. Strong non-uniformity is observed in mental sweating where the amount of excess sweat is different for each sweat gland although the sweat glands are adjacent to each other. The non-uniformity should be necessary to adjust as precisely the total amount of excess sweat as possible through the sympathetic nerve in response to strength of the stress.

Improving the translation of intentions into health actions: The role of motivational coherence.

PubMed

Sheeran, Paschal; Conner, Mark

2017-11-01

This paper introduces a new construct termed motivational coherence , and tests its influence upon the process of translating intentions into health actions. Motivational coherence was defined as the extent to which predictors of intentions (e.g., attitudes, norms, perceived control) cohere or point in the same direction. The prediction tested was that motivational coherence would stabilize intentions and thereby increase intention-behavior consistency. Three studies were conducted that each involved prospective designs. Study 1 (N = 248) concerned breastfeeding among nulliparous, low-income women. Study 2 (N = 651) concerned physical activity, and Study 3 (N = 635) examined uptake of smoking among adolescents. Motivational coherence moderated intention-behavior relations in all 3 studies. Greater motivational coherence was associated with a stronger relationship between intentions and action. This finding also held when other predictors of intention (Studies 1-3) and past behavior (Studies 2-3) were taken into account. Study 3 tested and found support for the idea that temporal stability of intention mediated the moderating effect of motivational coherence. The present studies suggest that future research on predicting health behaviors should consider not only the strength of people's intentions to act but also whether the basis of respective intentions is motivationally coherent.

This study examined the utility of a lifetime cumulative adversities and trauma model in predicting the severity of mental health symptoms of depression, anxiety, and posttraumatic stress disorder. We also tested whether ethnicity and gender moderate the effects of this stress exposure construct on mental health using multigroup structural equation modeling. A sample of 500 low-socioeconomic status African American and Latino men and women with histories of adversities and trauma were recruited and assessed with a standard battery of self-report measures of stress and mental health. Multiple-group structural equation models indicated good overall model fit. As hypothesized, experiences of discrimination, childhood family adversities, childhood sexual abuse, other childhood trauma, and chronic stresses all loaded on the latent cumulative burden of adversities and trauma construct (CBAT). The CBAT stress exposure index in turn predicted the mental health status latent variable. Although there were several significant univariate ethnic and gender differences, and ethnic and gender differences were observed on several paths, there were no significant ethnic differences in the final model fit of the data. These findings highlight the deleterious consequences of cumulative stress and trauma for mental health and underscore a need to assess these constructs in selecting appropriate clinical interventions for reducing mental health disparities and improving human health.

The structure of post-traumatic stress disorder and complex post-traumatic stress disorder amongst West Papuan refugees.

2015-05-07

The validity of applying the construct of post-traumatic stress disorder (PTSD) across cultures has been the subject of contention. Although PTSD symptoms have been identified across multiple cultures, questions remain whether the constellation represents a coherent construct with an interpretable factor structure across diverse populations, especially those naïve to western notions of mental disorder. An important additional question is whether a constellation of Complex-PTSD (C-PTSD) can be identified and if so, whether there are distinctions between that disorder and core PTSD in patterns of antecedent traumatic events. Our study amongst West Papuan refugees in Papua New Guinea (PNG) aimed to examine the factorial structure of PTSD based on the DSM-IV, DSM-5, ICD-10 and ICD-11 definitions, and C-PTSD according to proposed ICD-11 criteria. We also investigated domains of traumatic events (TEs) and broader psychosocial effects of conflict (sense of safety and injustice) associated with the factorial structures identified. Culturally adapted measures were applied to assess exposure to conflict-related traumatic events (TEs), refugees' sense of safety and justice, and symptoms of PTSD and C-PTSD amongst 230 West Papuan refugees residing in Port Morseby, PNG. Confirmatory factor analysis (CFA) supported a unitary construct of both ICD-10 and ICD-11 PTSD, comprising the conventional symptom subdomains of intrusion, avoidance, and hyperarousal. In contrast, CFA did not identify a unitary construct underlying C-PTSD. The interaction of witnessing murders and sense of injustice was associated with both the intrusion and avoidance domains of PTSD, but not with the unique symptom clusters characterizing C-PTSD. Our findings support the ICD PTSD construct and its three-factor structure in this transcultural refugee population. Traumatic experiences of witnessing murder associated with a sense of injustice were specifically related to the intrusion and avoidance domains of PTSD. The unitary nature of C-PTSD across cultures remains in question.

Background bvFTD patients display an impairment in the attribution of cognitive and affective states to others, reflecting GM atrophy in brain regions associated with social cognition, such as amygdala, superior temporal cortex and posterior insula. Distinctive patterns of abnormal brain functioning at rest have been reported in bvFTD, but their relationship with defective attribution of affective states has not been investigated. Objective To investigate the relationship among resting-state brain activity, gray matter (GM) atrophy and the attribution of mental states in the behavioral variant of fronto-temporal degeneration (bvFTD). Methods We compared 12 bvFTD patients with 30 age- and education-matched healthy controls on a) performance in a task requiring the attribution of affective vs. cognitive mental states; b) metrics of resting-state activity in known functional networks; and c) the relationship between task-performances and resting-state metrics. In addition, we assessed a connection between abnormal resting-state metrics and GM atrophy. Results Compared with controls, bvFTD patients showed a reduction of intra-network coherent activity in several components, as well as decreased strength of activation in networks related to attentional processing. Anomalous resting-state activity involved networks which also displayed a significant reduction of GM density. In patients, compared with controls, higher affective mentalizing performance correlated with stronger functional connectivity between medial prefrontal sectors of the default-mode and attentional/performance monitoring networks, as well as with increased coherent activity in components of the executive, sensorimotor and fronto-limbic networks. Conclusions Some of the observed effects may reflect specific compensatory mechanisms for the atrophic changes involving regions in charge of affective mentalizing. The analysis of specific resting-state networks thus highlights an intermediate level of analysis between abnormal brain structure and impaired behavioral performance in bvFTD, reflecting both dysfunction and compensation mechanisms.

2017-12-01

Major developments in attachment research over the past 2 decades have introduced parental mentalization as a predictor of infant-parent attachment security. Parental mentalization is the degree to which parents show frequent, coherent, or appropriate appreciation of their infants' internal states. The present study examined the triangular relations between parental mentalization, parental sensitivity, and attachment security. A total of 20 effect sizes (N = 974) on the relation between parental mentalization and attachment, 82 effect sizes (N = 6,664) on the relation between sensitivity and attachment, and 24 effect sizes (N = 2,029) on the relation between mentalization and sensitivity were subjected to multilevel meta-analyses. The results showed a pooled correlation of r = .30 between parental mentalization and infant attachment security, and rs of .25 for the correlations between sensitivity and attachment security, and between parental mentalization and sensitivity. A meta-analytic structural equation model was performed to examine the combined effects of mentalization and sensitivity as predictors of infant attachment. Together, the predictors explained 12% of the variance in attachment security. After controlling for the effect of sensitivity, the relation between parental mentalization and attachment remained, r = .24; the relation between sensitivity and attachment remained after controlling for parental mentalization, r = .19. Sensitivity also mediated the relation between parental mentalization and attachment security, r = .07, suggesting that mentalization exerts both direct and indirect influences on attachment security. The results imply that parental mentalization should be incorporated into existing models that map the predictors of infant-parent attachment.

Noncommutative coherent states and related aspects of Berezin-Toeplitz quantization

Hasibul Hassan Chowdhury, S.; Twareque Ali, S.; Engliš, Miroslav

2017-05-01

In this paper, we construct noncommutative coherent states using various families of unitary irreducible representations (UIRs) of Gnc , a connected, simply connected nilpotent Lie group, which was identified as the kinematical symmetry group of noncommutative quantum mechanics for a system of two degrees of freedom in an earlier paper. Similarly described are the degenerate noncommutative coherent states arising from the degenerate UIRs of Gnc . We then compute the reproducing kernels associated with both these families of coherent states and study the Berezin-Toeplitz quantization of the observables on the underlying 4-dimensional phase space, analyzing in particular the semi-classical asymptotics for both these cases. Dedicated by the first and the third authors to the memory of the second author, with gratitude for his friendship and for all they learnt from him.

An integrative theoretical framework of acculturation and salutogenesis.

PubMed

Riedel, Jeannette; Wiesmann, Ulrich; Hannich, Hans-Joachim

2011-12-01

During the last two decades, the number of international migrants worldwide has constantly risen. In this context, cross-cultural dimensions of psychological disorders receive increased attention, especially depression, anxiety and post-traumatic stress disorders among the migrant population. In this paper we propose a theoretical framework for the understanding of migrant mental health. This framework combines elements from Berry's acculturation model and Antonovsky's salutogenic theory. The former illustrates the main factors that affect an individual's adaptation in a new cultural context. The term acculturative stress denotes unresolved problems resulting from intercultural contact that cannot be overcome easily by simply adjusting or assimilating. The latter specifies the relationship between culturally associated stress and mental health more distinctive, introducing the concepts of generalized resistance resources and sense of coherence that determine mental health outcomes of migrants during acculturative stress periods. Specifically, we provide an integrative framework of acculturation and salutogenesis that helps to integrate inconsistent findings in the migrant mental health literature. The current paper focuses on the effect of resource factors for positive mental health outcomes in the migrant population and summarises some implications for future research activities.

Path induced coherent energy transfer in light-harvesting complexes in purple bacteria

2014-09-01

Features of path dependent energy transfer in a dual-ring light-harvesting (LH2) complexes (B850) system have been examined in detail systematically. The Frenkel-Dirac time dependent variational method with the Davydov D1 Ansatz is employed with detailed evolution of polaron dynamics in real space readily obtained. It is found that the phase of the transmission amplitude through the LH2 complexes plays an important role in constructing the coherent excitonic energy transfer. It is also found that the symmetry breaking caused by the dimerization of bacteriochlorophylls and coherence or correlation between two rings will be conducive in enhancing the exciton transfer efficiency.

We propose a method to improve the resolution of coherent anti-Stokes Raman scattering microscopy (CARS), and present a theoretical model. The proposed method, coherent anti-Stokes Raman scattering difference microscopy (CARS-D), is based on the intensity difference between two differently acquired images. One being the conventional CARS image, and the other obtained when the sample is illuminated by a doughnut shaped spot. The final super-resolution CARS-D image is constructed by intensity subtraction of these two images. However, there is a subtractive factor between them, and the theoretical model sets this factor to obtain the best imaging effect.

We show that such a quantum-walk system can construct an X-gate of a single qubit as well as a control gate for two qubits, when the potential is much larger than the hopping strength. We investigate the decoherence effect and find that the coherence time can be enhanced by either increasing the number of sites on the graph or the ratio of the potential to the hopping strength, which is expected to motivate the design of the quantum gate with long coherence time. We also suggest several experimental proposals to realize such a system.

Dimensional structures underlying the Wechsler Memory Scale-Fourth Edition (WMS-IV) and Wechsler Memory Scale-Third Edition (WMS-III) were compared to determine whether the revised measure has a more coherent and clinically relevant factor structure. Principal component analyses were conducted in normative samples reported in the respective technical manuals. Empirically supported procedures guided retention of dimensions. An invariant two-dimensional WMS-IV structure reflecting constructs of auditory learning/memory and visual attention/memory (C1 = .97; C2 = .96) is more theoretically coherent than the replicable, heterogeneous WMS-III dimension (C1 = .97). This research suggests that the WMS-IV may have greater utility in identifying lateralized memory dysfunction.

It is shown that each one of the Lie algebras su(1 , 1) and su(2) determine the spectrum of the radial oscillator. States that share the same orbital angular momentum are used to construct the representation spaces of the non-compact Lie group SU(1 , 1) . In addition, three different forms of obtaining the representation spaces of the compact Lie group SU(2) are introduced, they are based on the accidental degeneracies associated with the spherical symmetry of the system as well as on the selection rules that govern the transitions between different energy levels. In all cases the corresponding generalized coherent states are constructed and the conditions to squeeze the involved quadratures are analyzed.

[An explanatory model of behavior toward mental illness].

García-Sílberman, Sarah

2002-01-01

To evaluate a theoretical model designed to explain behaviors toward mental illness, considering some variables related to the construct. A survey was conducted in 1996 on mental disorder beliefs, attitudes, and behavioral intentions. The sample population was stratified by socioeconomic status, age, and gender. Study subjects were 800 individuals from Mexico City's general population. A data collection instrument was constructed and validated, consisting of 120 Likert-type items with five options each. Data were coded and analyzed with the software package SPSS. Internal consistency of the scales was assessed using Cronbach's alpha and construct validity with factorial analysis. Student's t test and ANOVA were used to compare the groups in the different strata. The model allowed to confirm the predictive capacity of the causal chain connecting beliefs, attitudes, and intentions; nevertheless, other study variables did not contribute to explain it, and behavior was scarcely influenced by intentions, depending mainly on experimented necessity. Study findings constitute a basis to understand the attitudes of shame and fear usually related to mental illnesses, to plan efficient actions aimed at modifying them, and to design programs to promote mental health.

Recent studies have shown that perceived social support is associated with gratitude and sense of coherence, but evidence for this concept remains scarce. In the present study, we investigated relationships between social support, gratitude, and sense of coherence, focusing on the construct of and source of social support among young women. The study was conducted in 2014 in Japan. Participants comprised 208 female university students (aged 19.9 ± 1.1 years), who completed a self-administered anonymous questionnaire regarding perceived social support, gratitude, and sense of coherence. Emotional and instrumental social support from acquaintances were found to be lower than those from family and friends. Gratitude was positively correlated with all forms of social support except instrumental social support from acquaintances. However, sense of coherence was positively correlated with both emotional and instrumental social support from family and only emotional social support from acquaintances. Multiple regression analysis showed that emotional support from family and emotional support from acquaintances were positively associated with gratitude whereas emotional support from family was associated with sense of coherence. These results indicate that emotional social support from family was related to both gratitude and sense of coherence.

Role of initial coherence on entanglement dynamics of two qubit X states

Bipartite entanglement is a necessary resource in most processes in quantum information science. Decoherence resulting from the interaction of the bipartite system with environment not only degrades the entanglement, but can result in abrupt disentanglement, known as entanglement sudden death (ESD). In some cases, a subsequent revival of entanglement is also possible. ESD is an undesirable feature for the state to be used as a resource in applications. In order to delay or avoid ESD, it is necessary to understand its origin. In this work we investigate the role of initial coherence on entanglement dynamics of a spatially separated two qubit system in a common vacuum reservoir with dipolar interaction. We construct two classes of X states, namely, states with one photon coherence (X 1) and states with two photon coherence (X 2). Considering them as initial states, we study entanglement dynamics under Markov approximation. We find for states in X 1, ESD time, revival time and time over which the state remains disentangled increase with increase in coherence. On the other hand for states in X 2, with increase in coherence ESD time increases, revival time remains same and time of disentanglement decreases. Thus, states with two photon coherence are better resources for applications since their entanglement is robust against decoherence compared to states with one photon coherence.

Background and Objective: Patient’s perception of their illness influences their healthcare decisions. The objectives of this study were to explore patient’s own beliefs about their illness (Schizophrenia) and perceived social support, and its impact on their attitudes toward pharmacological treatment in Lahore, Pakistan. Methods: This study was conducted at Mayo Hospital Lahore from March to September 2016. Hundred individuals suffering from Schizophrenia completed four questionnaires; a socio-demographic questionnaire, the Illness Perception Questionnaire for Schizophrenia(IPQ-S), Drug attitude Inventory-10 (DAI) and Multidimensional Scale of Perceived Social Support (PSS). Results: Stress, family problems, lack of friends & financial worries were endorsed strongly by patients as cause of their mental illness. Ambiguity regarding their mental illness duration and personal control was observed. Patients’ perceived significant negative consequences, negative emotional response, as well as had poor understanding of their mental illness and treatment effectiveness. Statistically significant gender differences in treatment control and illness coherence subscales of IPQS were observed. Drug attitude inventory was positively correlated with Treatment control subscale (p < .01) and negatively correlated with Illness coherence subscale of IPQS (p < .05). The negative consequences subscale and perceived social support was negatively correlated (p < .01). Conclusion: Patient’s perception about their own illness is predictor of their drug taking attitude and perceived social support. Study results should help to develop new interventions to correct inaccurate beliefs in patients with schizophrenia to improve illness outcome. PMID:29067048

Dynamical Fano-Like Interference between Rabi Oscillations and Coherent Phonons in a Semiconductor Microcavity System.

Yoshino, S; Oohata, G; Mizoguchi, K

2015-10-09

We report on dynamical interference between short-lived Rabi oscillations and long-lived coherent phonons in CuCl semiconductor microcavities resulting from the coupling between the two oscillations. The Fourier-transformed spectra of the time-domain signals obtained from semiconductor microcavities by using a pump-probe technique show that the intensity of the coherent longitudinal optical phonon of CuCl is enhanced by increasing that of the Rabi oscillation, which indicates that the coherent phonon is driven by the Rabi oscillation through the Fröhlich interaction. Moreover, as the Rabi oscillation frequency decreases upon crossing the phonon frequency, the spectral profile of the coherent phonon changes from a peak to a dip with an asymmetric structure. The continuous wavelet transformation reveals that these peak and dip structures originate from constructive and destructive interference between Rabi oscillations and coherent phonons, respectively. We demonstrate that the asymmetric spectral structures in relation to the frequency detuning are well reproduced by using a classical coupled oscillator model on the basis of dynamical Fano-like interference.

To investigate the relationship between sense of coherence, psychological distress and health related quality of life in inflammatory bowel disease (IBD). This cross-sectional study enrolled a consecutive sample of 147 IBD (aged 45.1 ± 14.1 years; 57.1% female) patients recruited from a tertiary gastroenterology service. Sixty-four participants met diagnostic criteria for Crohn's disease, while eighty-three patients had ulcerative colitis. Socio-demographic data (education, age, race, gender, gross monthly income and marital status), disease-related variables (illness activity, relapse rate in past 2 years, history of surgery and time since diagnosis), sense of coherence (Antonovsky's SOC scale), psychological distress symptoms (Hospital Anxiety and Depression Scale) and health-related quality of life (HRQoL; WHOQOL-Bref) were assessed. Hierarchical multiple regression analyses were performed to identify factors that are independently associated with psychological distress and HRQoL in patients with IBD and to provide indications for possible moderating or mediating effects. In addition, formal moderation and mediation analyses (Sobel tests) were performed to confirm potential moderators/mediators of the relationship between SOC, psychological distress symptoms and HRQoL. Lower SOC scores (std beta= -0.504; P < 0.001), female gender (std beta = 0.176; P = 0.021) and White race (std beta = 0.164; P = 0.033) were independently associated with higher levels of depressive symptoms, while lower levels of SOC (std beta = -0.438; P < 0.001) and higher relapse rate (std beta = 0.161; P = 0.033) were independently associated with more severe anxiety symptoms. A significant interaction between time since diagnosis and SOC was found with regard to the severity of depressive or anxiety symptoms, as the interaction term (time since diagnosis X SOC) had beta coefficients of -0.191 (P = 0.009) and -0.172 (P = 0.026), respectively. Lower levels of anxiety symptoms (std beta = -0.369; P < 0.001), higher levels of SOC (std beta = 0.231; P = 0.016) and non-White race (std beta = -0.229; P = 0.006), i.e., mixed-race, which represented the reference category, were independently associated with higher levels of overall HRQoL. Anxiety symptoms were the most potent independent correlate of most aspects of HRQoL. In addition, anxiety mediated the association between SOC and satisfaction with health, as well as its relationship with physical, mental, and social relations HRQoL. Depressive symptoms also mediated the association between SOC and mental HRQoL. Our data indicated that SOC is an important construct, as it influences psychological distress and has significant albeit indirect effects on several HRQoL domains in IBD.

Mental simulation of routes during navigation involves adaptive temporal compression

Arnold, Aiden E.G.F.; Iaria, Giuseppe; Ekstrom, Arne D.

2016-01-01

Mental simulation is a hallmark feature of human cognition, allowing features from memories to be flexibly used during prospection. While past studies demonstrate the preservation of real-world features such as size and distance during mental simulation, their temporal dynamics remains unknown. Here, we compare mental simulations to navigation of routes in a large-scale spatial environment to test the hypothesis that such simulations are temporally compressed in an adaptive manner. Our results show that simulations occurred at 2.39x the speed it took to navigate a route, increasing in compression (3.57x) for slower movement speeds. Participant self-reports of vividness and spatial coherence of simulations also correlated strongly with simulation duration, providing an important link between subjective experiences of simulated events and how spatial representations are combined during prospection. These findings suggest that simulation of spatial events involve adaptive temporal mechanisms, mediated partly by the fidelity of memories used to generate the simulation. PMID:27568586

Women-specific mental disorders in DSM-V: are we failing again?

PubMed

Wittchen, Hans-Ulrich

2010-02-01

Despite a wealth of studies on differences regarding the biobehavioral and social-psychological bases of mental disorders in men and women and repeated calls for increased attention, women-specific issues have so far not been comprehensively addressed in past diagnostic classification systems of mental disorders. There is also increasing evidence that this situation will not change significantly in the upcoming revisions of ICD-11 and DSM-V. This paper explores reasons for this continued failure, highlighting three major barriers: the fragmentation of the field of women's mental health research, lack of emphasis on diagnostic classificatory issues beyond a few selected clinical conditions, and finally, the "current rules of game" used by the current DSM-V Task Forces in the revision process of DSM-V. The paper calls for concerted efforts of researchers, clinicians, and other stakeholders within a more coherent and comprehensive framework aiming at broader coverage of women-specific diagnostic classificatory issues in future diagnostic systems.

We challenge the idea that a cognitive perspective on therapeutic change concerns only memory processes. We argue that inclusion of impairments in more generative cognitive processes is necessary for complete understanding of cases such as depression. In such cases what is identified in the target article as an "integrative memory structure" is crucially supported by processes of mental model construction.

Mental health literacy (MHL), or the knowledge and abilities necessary to benefit mental health, is a significant determinant of mental health and has the potential to benefit both individual and public mental health. MHL and its measures have traditionally focused on knowledge and beliefs about mental -ill-health rather than on mental health. No measures of MHL addressing knowledge of good or positive mental health have been identified. This study aimed to develop and validate an instrument measuring adolescents' knowledge of how to obtain and maintain good mental health and to evaluate the psychometric properties of the instrument. More specifically, the factor structure, internal and construct validity, and test-retest reliability were assessed. The participants were Norwegian upper secondary school students aged 15-21 years. The development and validation of the instrument entailed three phases: 1) item generation based on the basic psychological needs theory (BPNT), focus group interviews, and a narrative literature review, 2) a pilot study (n = 479), and 3) test-retest (n = 149), known-groups validity (n = 44), and scale construction, item reduction through principal component analysis (PCA), and confirmatory factor analysis (CFA) for factor structure and psychometric properties assessment (n = 1888). Thirty-two items were initially generated, and 15 were selected for the pilot study. PCA identified cross-loadings, and a one-factor solution was examined. After removing five problematic items, CFA yielded a satisfactory fit for a 10-item one-factor model, referred to as the mental health-promoting knowledge (MHPK-10) measure. The test-retest evaluation supported the stability of the measure. McDonald's omega was 0.84, and known-groups validity test indicated good construct validity. A valid and reliable one-dimensional instrument measuring knowledge of factors promoting good mental health among adolescents was developed. The instrument has the potential to complement current measures of MHL and may be useful when planning mental health promotion activities and evaluating public mental health education initiatives in adolescents.

The purpose of this study was to construct QOL models for the elderly that included ikigai as a composition factor and to clarify differences in two kinds of models, one constructed for the elderly with habitual exercise and the other for those without it. The subjects were 1,566 healthy community-dwelling independent people aged 60 years or more (752 males, 814 females). First, the ratio of subjects with ikigai was calculated. The ratios of subjects with different kinds of objects of ikigai were also calculated. Next, structural equation models (SEM) were constructed on the basis of social, physical, and mental QOL and ikigai. Fits of the models were evaluated. To examine whether the presence or absence of habitual exercise caused any difference in the QOL model, subjects were divided into 4 groups according to whether they were male or female and whether they had or did not have an exercise habit. Multi-population group simultaneous analysis was then performed among the four groups. More than 85% of the subjects had objects of ikigai. Ikigai is an important factor for comprehending the QOL of the elderly. It was possible to construct QOL models for the elderly with ikigai as a composition factor. The effect of physical QOL on mental QOL was negligible in females irrespective of whether they had an exercise habit. The effect of social QOL on mental QOL was profound in aged females with an exercise habit. The effect of the living situation on mental QOL was profound in aged females without an exercise habit. The effect of mental QOL on ikigai was more marked in subjects without an exercise habit than in those with an exercise habit.

2017-09-01

To elucidate the mechanism through which internalized stigma reduces the quality of life (QoL) of people with mental illness by exploring the mediating roles of self-esteem and sense of coherence (SOC). A cross-sectional analysis of 229 patients diagnosed with schizophrenia or affective disorders was undertaken to test a sequential mediation model assuming that more severe internalized stigma is related to lower self-esteem, which is associated with weaker SOC, which in turn relates to worse QoL. The proposed model was supported by the data. A sequential indirect effect from internalized stigma to QoL via self-esteem and SOC turned out to be significant [beta = -0.06, SE = 0.02; 95% CI (-0.11, -0.03)]. Support was also found for simple mediation models with either self-esteem or SOC as single mediators between internalized stigma and QoL. Self-esteem and SOC are personal resources that should be considered as potential targets of interventions aiming to prevent the harmful consequences of internalized stigma for the QoL of people receiving psychiatric treatment.

Future commercialization of glasses-free holographic real 3D displays requires not only appropriate image quality but also slim design of backlight unit and whole display device to match market needs. While a lot of research aimed to solve computational issues of forming Computer Generated Holograms for 3D Holographic displays, less focus on development of backlight units suitable for 3D holographic display applications with form-factor of conventional 2D display systems. Thereby, we report coherent backlight unit for 3D holographic display with thickness comparable to commercially available 2D displays (cell phones, tablets, laptops, etc.). Coherent backlight unit forms uniform, high-collimated and effective illumination of spatial light modulator. Realization of such backlight unit is possible due to holographic optical elements, based on volume gratings, constructing coherent collimated beam to illuminate display plane. Design, recording and measurement of 5.5 inch coherent backlight unit based on two holographic optical elements are presented in this paper.

2011-03-01

This study explored relationships between perspective-taking, emotion understanding, and children's narrative abilities. Younger (23 5-/6-year-olds) and older (24 7-/8-year-olds) children generated fictional narratives, using a wordless picture book, about a frog experiencing jealousy. Children's emotion understanding was assessed through a standardized test of emotion comprehension and their ability to convey the jealousy theme of the story. Perspective-taking ability was assessed with respect to children's use of narrative evaluation (i.e., narrative coherence, mental state language, supplementary evaluative speech, use of subjective language, and placement of emotion expression). Older children scored higher than younger children on emotion comprehension and on understanding the story's complex emotional theme, including the ability to identify a rival. They were more advanced in perspective-taking abilities, and selectively used emotion expressions to highlight story episodes. Subjective perspective taking and narrative coherence were predictive of children's elaboration of the jealousy theme. Use of supplementary evaluative speech, in turn, was predictive of both subjective perspective taking and narrative coherence. ©2010 The British Psychological Society.

Counting abilities in autism: possible implications for central coherence theory.

PubMed

Jarrold, C; Russell, J

1997-02-01

We examined the claim that children with autism have a "weak drive for central coherence" which biases them towards processing information at an analytic rather than global level. This was done by investigating whether children with autism would rapidly and automatically enumerate a number of dots presented in a canonical form, or count each dot individually to obtain the total. The time taken to count stimuli was compared across three participant groups: children with autism, children with moderate learning difficulties, and normally developing children. There were 22 children in each group, and individuals were matched across groups on the basis of verbal mental age. Results implied that children with autism did show a tendency towards an analytic level of processing. However, though the groups differed on measures of counting speeds, the number or children showing patterns of global or analytic processing did not differ significantly across the groups. Whether these results implicate a weak drive for central coherence in autism, which is both specific to, and pervasive in the disorder, is discussed.

Background Digital game-based learning (DGBL) makes use of the entertaining power of digital games for educational purposes. Effectiveness assessment of DGBL programs has been underexplored and no attempt has been made to simultaneously model both important components of DGBL: learning attainment (ie, educational purposes of DGBL) and engagement of users (ie, entertaining power of DGBL) in evaluating program effectiveness. Objective This study aimed to describe and evaluate an Internet-based DGBL program, Professor Gooley and the Flame of Mind, which promotes mental health to adolescents in a positive youth development approach. In particular, we investigated whether user engagement in the DGBL program could enhance their attainment on each of the learning constructs per DGBL module and subsequently enhance their mental health as measured by psychological well-being. Methods Users were assessed on their attainment on each learning construct, psychological well-being, and engagement in each of the modules. One structural equation model was constructed for each DGBL module to model the effect of users' engagement and attainment on the learning construct on their psychological well-being. Results Of the 498 secondary school students that registered and participated from the first module of the DGBL program, 192 completed all 8 modules of the program. Results from structural equation modeling suggested that a higher extent of engagement in the program activities facilitated users’ attainment on the learning constructs on most of the modules and in turn enhanced their psychological well-being after controlling for users’ initial psychological well-being and initial attainment on the constructs. Conclusions This study provided evidence that Internet intervention for mental health, implemented with the technologies and digital innovations of DGBL, could enhance youth mental health. Structural equation modeling is a promising approach in evaluating the effectiveness of DGBL programs. PMID:27717921

Physiotherapy Students' Attitudes toward Psychiatry and Mental Health: A Cross-Sectional Study.

PubMed

Connaughton, Joanne; Gibson, William

Purpose: A cross-sectional exploration of Notre Dame Australia physiotherapy students' attitudes toward psychiatry and mental illness, students' perceptions regarding preparation in this area for general clinical practice, and a cross-sectional investigation of current mental health-and psychiatry-related content in physiotherapy curricula across Australia and New Zealand. Methods: A questionnaire including demographic details, level of exposure to mental illness, and the Attitudes Toward Psychiatry-30 items (ATP-30) was completed by pre-clinical and clinically experienced physiotherapy students from the University of Notre Dame Australia. Students with clinical experience were asked additional questions about preparedness for practice. Staff of 10 of 17 physiotherapy programmes across Australia and New Zealand responded to an online questionnaire investigating relevant content and quantity of learning experiences in mental health. Results: Student response rate was 89%. Students generally had a positive attitude about psychiatry and mental health. Women were significantly more positive than men, and students who had completed clinical experience had a significantly more positive attitude. Physiotherapy program responses (response rate=59%) highlighted disparate approaches to psychiatry and mental health learning opportunities in terms of quantity and content. Conclusion: Entry-level physiotherapy students who have clinical experience generally have a more positive attitude toward psychiatry and people with mental illness. Given the prevalence of mental health problems and the increase in physical and mental health comorbidities, it is imperative that future clinicians have positive educational experiences in psychiatry. A coherent, integrated approach to mental illness and psychiatry is suggested for entry-level physiotherapy programmes in Australia and New Zealand.

Methods: A questionnaire including demographic details, level of exposure to mental illness, and the Attitudes Toward Psychiatry–30 items (ATP-30) was completed by pre-clinical and clinically experienced physiotherapy students from the University of Notre Dame Australia. Students with clinical experience were asked additional questions about preparedness for practice. Staff of 10 of 17 physiotherapy programmes across Australia and New Zealand responded to an online questionnaire investigating relevant content and quantity of learning experiences in mental health. Results: Student response rate was 89%. Students generally had a positive attitude about psychiatry and mental health. Women were significantly more positive than men, and students who had completed clinical experience had a significantly more positive attitude. Physiotherapy program responses (response rate=59%) highlighted disparate approaches to psychiatry and mental health learning opportunities in terms of quantity and content. Conclusion: Entry-level physiotherapy students who have clinical experience generally have a more positive attitude toward psychiatry and people with mental illness. Given the prevalence of mental health problems and the increase in physical and mental health comorbidities, it is imperative that future clinicians have positive educational experiences in psychiatry. A coherent, integrated approach to mental illness and psychiatry is suggested for entry-level physiotherapy programmes in Australia and New Zealand. PMID:27909364

Research into positive aspects of the psyche is growing as psychologists learn more about the protective role of positive processes in the development and course of mental disorders, and about their substantial role in promoting mental health. With increasing globalization, there is strong interest in studies examining positive constructs across cultures. To obtain valid cross-cultural comparisons, measurement invariance for the scales assessing positive constructs has to be established. The current study aims to assess the cross-cultural measurement invariance of questionnaires for 6 positive constructs: Social Support (Fydrich, Sommer, Tydecks, & Brähler, 2009), Happiness (Subjective Happiness Scale; Lyubomirsky & Lepper, 1999), Life Satisfaction (Diener, Emmons, Larsen, & Griffin, 1985), Positive Mental Health Scale (Lukat, Margraf, Lutz, van der Veld, & Becker, 2016), Optimism (revised Life Orientation Test [LOT-R]; Scheier, Carver, & Bridges, 1994) and Resilience (Schumacher, Leppert, Gunzelmann, Strauss, & Brähler, 2004). Participants included German (n = 4,453), Russian (n = 3,806), and Chinese (n = 12,524) university students. Confirmatory factor analyses and measurement invariance testing demonstrated at least partial strong measurement invariance for all scales except the LOT-R and Subjective Happiness Scale. The latent mean comparisons of the constructs indicated differences between national groups. Potential methodological and cultural explanations for the intergroup differences are discussed.

The aim of this study was to evaluate the psychometric properties of the Beliefs Toward Mental Illness Scale (BMI) across women from the United States, Japan, and South Korea. A cross-sectional study design was employed. The sample was 564 women aged 21-64 years old who were recruited in the United States and Korea (American = 127, Japanese immigrants in the United States = 204, and Korean = 233). We carried out item analysis, construct validity by confirmatory factor analysis (CFA), and internal consistency using SPSS Version 22 and AMOS Version 22. An acceptable model fit for a 20-item BMI (Beliefs Toward Mental Illness Scale-Revised [BMI-R]) with 3 factors was confirmed using CFA. Construct validity of the BMI-R showed to be all acceptable; convergent validity (average variance extracted [AVE] ≥0.5, construct reliability [CR] ≥0.7) and discriminant validity (r = .65-.89, AVE >.79). The Cronbach's alpha of the BMI-R was .92. These results showed that the BMI was a reliable tool to study beliefs about mental illness across cultures. Our findings also suggested that continued efforts to reduce stigma in culturally specific contexts within and between countries are necessary to promote help-seeking for those suffering from psychological distress.

2018-05-01

The method of integrals of motion is used to construct families of generalized coherent states of a nonrelativistic spinless charged particle in a constant electric field. Families of states, differing in the values of their standard deviations at the initial time, are obtained. Depending on the initial values of the standard deviations, and also on the electric field, it turns out to be possible to identify some families with semiclassical states.

Participation in mental healthcare: a qualitative meta-synthesis.

Stomski, Norman J; Morrison, Paul

2017-01-01

Facilitation of service user participation in the co-production of mental healthcare planning and service delivery is an integral component of contemporary mental health policy and clinical guidelines. However, many service users continue to experience exclusion from the planning of their care. This review synthesizes qualitative research about participation in mental healthcare and articulates essential processes that enable service user participation in mental health care. Electronic databases were systematically searched. Studies were included if they were peer reviewed qualitative studies, published between 2000 and 2015, examining participation in mental health care. The Critical Appraisal Skills Program checklist was used to assess the quality of each included study. Constant comparison was used to identify similar constructs across several studies, which were then abstracted into thematic constructs. The synthesis resulted in the identification of six principal themes, which articulate key processes that facilitate service user participation in mental healthcare. These themes included: exercising influence; tokenism; sharing knowledge; lacking capacity; respect; and empathy. This meta-synthesis demonstrates that service user participation in mental healthcare remains a policy aspiration, which generally has not been translated into clinical practice. The continued lack of impact on policy on the delivery of mental healthcare suggests that change may have to be community driven. Systemic service user advocacy groups could contribute critically to promoting authentic service user participation in the co-production of mental health services.

Time-dependent variational approach in terms of squeezed coherent states: Implication to semi-classical approximation

NASA Technical Reports Server (NTRS)

Tsue, Yasuhiko

1994-01-01

A general framework for time-dependent variational approach in terms of squeezed coherent states is constructed with the aim of describing quantal systems by means of classical mechanics including higher order quantal effects with the aid of canonicity conditions developed in the time-dependent Hartree-Fock theory. The Maslov phase occurring in a semi-classical quantization rule is investigated in this framework. In the limit of a semi-classical approximation in this approach, it is definitely shown that the Maslov phase has a geometric nature analogous to the Berry phase. It is also indicated that this squeezed coherent state approach is a possible way to go beyond the usual WKB approximation.

Mental Representation in The Thought of Sidney Blatt: Developmental Processes.

PubMed

Auerbach, John S; Diamond, Diana

2017-06-01

Mental representation was a central construct in Sidney Blatt's contributions to psychology and psychoanalysis. This brief review demonstrates that Blatt's understanding of representation was always informed by basic psychoanalytic concepts like the centrality of early caregiver-infant relationships and of unconscious mental processes. Although Blatt's earlier writings were informed by psychoanalytic ego psychology and Piagetian cognitive developmental psychology, they focused nonetheless on how an individual uses bodily and relational experiences to construct an object world; they also consistently presented object representations as having significant unconscious dimensions. From the mid-1980s onward, Blatt's contributions, in dialogue with his many students, moved in an even more experiential/relational direction and manifested the influence of attachment theory, parent-infant interaction research, and intersubjectivity theory. They also incorporated contemporary cognitive psychology, with its emphasis on implicit or procedural, rather than explicit, dimensions as a means of accounting for aspects of object representations that are not in conscious awareness. Throughout his career, however, Blatt regarded mental representation as the construct that mediates between the child's earliest bodily and relational experiences and the mature adult's symbolic, most emotionally profound capacities.

Characterizing the role of the hippocampus during episodic simulation and encoding.

PubMed

Thakral, Preston P; Benoit, Roland G; Schacter, Daniel L

2017-12-01

The hippocampus has been consistently associated with episodic simulation (i.e., the mental construction of a possible future episode). In a recent study, we identified an anterior-posterior temporal dissociation within the hippocampus during simulation. Specifically, transient simulation-related activity occurred in relatively posterior portions of the hippocampus and sustained activity occurred in anterior portions. In line with previous theoretical proposals of hippocampal function during simulation, the posterior hippocampal activity was interpreted as reflecting a transient retrieval process for the episodic details necessary to construct an episode. In contrast, the sustained anterior hippocampal activity was interpreted as reflecting the continual recruitment of encoding and/or relational processing associated with a simulation. In the present study, we provide a direct test of these interpretations by conducting a subsequent memory analysis of our previously published data to assess whether successful encoding during episodic simulation is associated with the anterior hippocampus. Analyses revealed a subsequent memory effect (i.e., later remembered > later forgotten simulations) in the anterior hippocampus. The subsequent memory effect was transient and not sustained. Taken together, the current findings provide further support for a component process model of hippocampal function during simulation. That is, unique regions of the hippocampus support dissociable processes during simulation, which include the transient retrieval of episodic information, the sustained binding of such information into a coherent episode, and the transient encoding of that episode for later retrieval. © 2017 Wiley Periodicals, Inc.

We assessed psychosocial work environment, the prevalence of mental health complaints and the association between these two among bricklayers and construction supervisors. For this cross-sectional study a total of 1500 bricklayers and supervisors were selected. Psychosocial work characteristics were measured using the Dutch Questionnaire on the Experience and Evaluation of Work and compared to the general Dutch working population. Mental health effects were measured with scales to assess fatigue during work, need for recovery after work, symptoms of distress, depression and post-traumatic stress disorder. The prevalence of self-reported mental health complaints was determined using the cut-off values. Associations between psychosocial work characteristics and self-reported mental health complaints were analysed using logistic regression. Total response rate was 43%. Compared to the general working population, bricklayers experienced statistically significant worse job control, learning opportunities and future perspectives; supervisors experienced statistically significant higher psychological demands and need for recovery. Prevalence of self-reported mental health effects among bricklayers and supervisors, respectively, were as follows: high need for recovery after work (14%; 25%), distress (5%, 7%), depression (18%, 20%) and post-traumatic stress disorder (11%, 7%). Among both occupations, high work speed and quantity were associated with symptoms of depression. Further, among construction supervisors, low participation in decision making and low social support of the direct supervisor was associated with symptoms of depression. The findings in the present study indicate psychosocial risk factors for bricklayers and supervisors. In each occupation a considerable proportion of workers was positively screened for symptoms of common mental disorders. Copyright © 2013 Elsevier Ltd and The Ergonomics Society.

Hostility, anger, and sense of coherence as predictors of health-related quality of life. Results of an ASCOT substudy.

PubMed

Julkunen, Juhani; Ahlström, Richard

2006-07-01

The aim of this study was to investigate the relationship of hostility and anger expression to sense of coherence (SOC) and their role as predictors of health-related quality of life (HQL). It was hypothesised that SOC would mediate the impact of hostility and anger on HQL. This is a substudy of the Anglo-Scandinavian Cardiac Outcomes Trial, which evaluates different treatment strategies to prevent cardiovascular disease in hypertensive patients. At baseline, SOC was assessed with a short form measure, and hostility-anger with the Cynical Distrust scale and with the Anger Expression scales. HQL was assessed at 6 months with the RAND-36. The sample comprised of 774 subjects (77.5% men). Results showed that strong SOC associates with ability to control expression of anger and with low levels of suppressed or openly expressed anger. Anger control and SOC were related to good HQL; cynicism, anger-out, and anger-in correlated negatively with HQL. Path models revealed that SOC was the strongest predictor of HQL while hostility and anger lost their direct impact on HQL. Given the significant associations of hostility and anger with SOC, it is concluded that the salutogenic theory of Antonovsky (A. Antonovsky, Health, Stress, and Coping: New Perspectives on Mental Health and Physical Well-Being, Jossey-Bass Inc, San Francisco, 1979) should be extended to include hostility-related constructs. The impact of hostility and anger on HQL is, to a great extent, mediated through SOC, which implies that in future studies, the role of hostility as a risk factor of ill health should be reconsidered from the SOC theory perspective.

Purpose Recent studies have shown that perceived social support is associated with gratitude and sense of coherence, but evidence for this concept remains scarce. In the present study, we investigated relationships between social support, gratitude, and sense of coherence, focusing on the construct of and source of social support among young women. Methods The study was conducted in 2014 in Japan. Participants comprised 208 female university students (aged 19.9 ± 1.1 years), who completed a self-administered anonymous questionnaire regarding perceived social support, gratitude, and sense of coherence. Results Emotional and instrumental social support from acquaintances were found to be lower than those from family and friends. Gratitude was positively correlated with all forms of social support except instrumental social support from acquaintances. However, sense of coherence was positively correlated with both emotional and instrumental social support from family and only emotional social support from acquaintances. Multiple regression analysis showed that emotional support from family and emotional support from acquaintances were positively associated with gratitude whereas emotional support from family was associated with sense of coherence. Conclusion These results indicate that emotional social support from family was related to both gratitude and sense of coherence. PMID:28721109

Attachment, Mothering and Mental Illness: Mother-Infant Therapy in an Institutional Context.

PubMed

Masciantonio, Sonia; Hemer, Susan R; Chur-Hansen, Anna

2018-03-01

This paper is an ethnographic exploration of how attachment theory underpins therapeutic practices in an Australian institutional context where mothers of infants have been diagnosed and are undergoing treatment for mental illness. We argue that attachment theory in this particular context rests on a series of principles or assumptions: that attachment theory is universally applicable; that attachment is dyadic and gendered; that there is an attachment template formed which can be transferred across generations and shapes future social interactions; that there is understood to be a mental health risk to the infant when attachment is characterised as problematic; and that this risk can be mitigated through the therapeutic practices advocated by the institution. Through an in-depth case study, this paper demonstrates how these assumptions cohere in practice and are used to assess mothering as deficient, to choose therapeutic options, to shape women's behaviour, and to formulate decisions about child placement.

Development of a group work assessment pedagogy using constructive alignment theory.

PubMed

Croy, Suzanne R

2018-02-01

The purpose of this paper is to explore group work assessment underpinned by constructive alignment theory to develop a new assessment pedagogy. A review was undertaken of an existing module 'Mental Health Nursing 1', with student nurses participating in the BSc (Hons) Nursing Programme. Constructive alignment theory requires teachers to adopt a deep approach to learning where module learning outcomes are aligned with the teaching environment and modes of assessment. As the module progressed, reviewing the Mental Health Nursing 1 module became an excellent opportunity to begin to understand how constructive alignment theory can inform a group work assessment pedagogy. Working using a constructively aligned assessment process became a valuable learning experience for the module leader whilst at the same time revealed a gap in the research around the impact of constructively aligned teaching and group work assessment.

The relationship between executive functioning, central coherence, and repetitive behaviors in the high-functioning autism spectrum.

PubMed

South, Mikle; Ozonoff, Sally; McMahon, William M

2007-09-01

This study examined the relationship between everyday repetitive behavior (primary symptoms of autism) and performance on neuropsychological tests of executive function and central coherence (secondary symptoms). It was hypothesized that the frequency and intensity of repetitive behavior would be positively correlated with laboratory measures of cognitive rigidity and weak central coherence. Participants included 19 individuals (ages 10-19) with high-functioning autism spectrum disorders (ASD group) and 18 age- and IQ-matched typically developing controls (TD group). There was partial support in the ASD group for the link between repetitive behavior and executive performance (the Wisconsin Card Sorting Task). There was no support for a link between repetitive behavior and measures of central coherence (a Gestalt Closure test and the Embedded Figures Test). Further research on repetitive behaviors in autism may benefit from a focus on narrow behavioral and cognitive constructs rather than general categories.

Classes of (p,q) deformations of the Jaynes-Cummings model in the rotating wave approximation are considered. Diagonalization of the Hamiltonian is performed exactly, leading to useful spectral decompositions of a series of relevant operators. The latter include ladder operators acting between adjacent energy eigenstates within two separate infinite discrete towers, except for a singleton state. These ladder operators allow for the construction of (p,q)-deformed vector coherent states. Using (p,q) arithmetics, explicit and exact solutions to the associated moment problem are displayed, providing new classes of coherent states for such models. Finally, in the limit of decoupled spin sectors, our analysis translatesmore » into (p,q) deformations of the supersymmetric harmonic oscillator, such that the two supersymmetric sectors get intertwined through the action of the ladder operators as well as in the associated coherent states.« less

Coherent states for quantum compact groups

NASA Astrophysics Data System (ADS)

Jurĉo, B.; Ŝťovíĉek, P.

1996-12-01

Coherent states are introduced and their properties are discussed for simple quantum compact groups A l, Bl, Cl and D l. The multiplicative form of the canonical element for the quantum double is used to introduce the holomorphic coordinates on a general quantum dressing orbit. The coherent state is interpreted as a holomorphic function on this orbit with values in the carrier Hilbert space of an irreducible representation of the corresponding quantized enveloping algebra. Using Gauss decomposition, the commutation relations for the holomorphic coordinates on the dressing orbit are derived explicitly and given in a compact R-matrix formulation (generalizing this way the q-deformed Grassmann and flag manifolds). The antiholomorphic realization of the irreducible representations of a compact quantum group (the analogue of the Borel-Weil construction) is described using the concept of coherent state. The relation between representation theory and non-commutative differential geometry is suggested.

[How our subjective coherence is built? The model of cognitive dissonance].

PubMed

Naccache, Lionel; El Karoui, Imen; Salti, Moti; Chammat, Mariam; Maillet, Mathurin; Allali, Sébastien

2015-01-01

Our conscious, subjective discourse, demonstrates a temporal coherence that distinguishes it from the many unconscious cognitive representations explored by cognitive neuroscience. This subjective coherence, --particularly its dynamics--can be modified in certain psychiatric syndromes including a " dissociative state " (e.g. schizophrenia), or in several neuropsychiatric disorders (e.g. frontal lobe syndrome). The medical and environmental consequences of these changes are significant. However, the psychological and neural mechanisms of this fundamental property remain largely unknown. We explored the dynamics of subjective coherence in an experimental paradigm (the "free choice "paradigm) originating for the field of cognitive dissonance. Using a series of behavioral experiments, conducted in healthy volunteers, we have discovered a key role for the episodic memory in the preference change process when simply making a choice. These results highlight the importance of conscious memory in the construction of subjective consistency, of which the subjects do not yet seem to be the conscious agents.

An ethnographic study of job seeking among people with severe mental illness.

Alverson, Hoyt; Carpenter, Elizabeth; Drake, Robert E

2006-01-01

An ethnographic study employing intensive participant observation methods identified critical differences in styles of searching for competitive employment among people with severe mental illness and explored the social/cultural correlates of these job-seeking styles. Propensity for active job seeking was strongly associated with younger age, with participants' involvement in interdependent kin networks or households, with ethno-racial minority background, and with capacity for coherent discourse. Active job seekers did particularly well in a supported employment program, but also were able to find employment when assigned to other programs; passive job seekers had little success in any vocational program. The authors discuss several implications of these findings for vocational services.

Li, Sarah; Hatzidimitriadou, Eleni; Psoinos, Maria

2014-08-01

In this article, the authors explored Cantonese-speaking older Chinese migrants knowledge, attitudes and expectations regarding mental illness. They obtained verbatim data from semi-structured interviews with eight participants recruited from London-based Chinese and church communities in Britain. They analyzed the data using the principles of Grounded Theory and in-depth content analysis. They examined cultural idioms in participants' accounts. Findings suggested that Western diagnostic categories of mental illness were alien to participants. They had a culturally constructed way of defining and characterizing mental illness. Participants used idioms of 'nerve', 'mood', 'behavior', 'personality', 'normal life', 'compassion' and the idiom of 'others' to construct an alternative world for stigma management. They erected an invisible but permeable barrier to limit access to their normal world. The role of traditional Chinese culture of Confucianism was significant in shaping perceptions and conceptions of mental illness. This article offered another perspective on the alternative world of Chinese migrants' cultural understandings of mental illness, an area with limited understanding at present. The authors discussed important implications for future research and social policy. Copyright © 2014 Elsevier Inc. All rights reserved.

The coherence of synthetic telomeres.

Acevedo, O L; Dickinson, L A; Macke, T J; Thomas, C A

1991-01-01

The chromosomal telomeres of Oxytricha were synthesized and their ability to cohere examined on non-denaturing acrylamide gels containing the stabilizing cation K+. At least 5 different mobility species were observed, in addition to that of the monomeric telomere. By cohering synthetic telomeres containing different lengths of subtelomeric DNA, we showed that each of the different mobility species was a dimer of two telomeres. Since the different mobility species did not differ in numbers or sequences of nucleotides, they must correspond to different molecular shapes probably caused by different degrees of bending of the dimer. Paradoxically, telomeres with longer subtelomeric stems cohered more efficiently. In the presence of K+, solutions had to be heated to over 90 degrees before the telomeres separated. Various synthetic constructs, restriction endonuclease and dimethyl sulfate protection experiments showed that the only nucleotides involved in the cohered structures were the 16 base 'tails' of sequence 3'G4T4G4T4. Extension of this motif was actually inimical to coherence. Oligomers containing 2 G4T4 motifs protected their GN7 positions by forming dimers, those with 5 G4T4 could do so by internal folding, but the 3' terminal group of G4 was left unprotected. This suggests that only four groups of G4 are necessary for the cohered structure. Single-chain specific nuclease, S1, as well as osmium tetroxide, which oxidizes the thymine residues of single chains, reacted less efficiently with the cohered structures. Synthetic telomeres containing inosine replacing guanosine were not observed to cohere, indicating that the C2-NH2 is strongly stabilizing. The cohered structures appear to be unusually compact and sturdy units in which four G4 blocks form quadruplexes stabilized by K+. A new model for the cohered structure is presented.

This intergroup case study compared users' mental models with an expert design model of a water management system in a green building. The system incorporates a constructed wetland component and a rainwater collection pond that together recycle water for re-use in the building and its surroundings. The sample consisted of five building occupants and the cleaner (6 users) and two experts who were involved with the design of the water management system. Users' mental model descriptions and the experts' design model were derived from in-depth interviews combined with self-constructed (and verified) diagrams. Findings from the study suggest that there is considerable variability in the user mental models that could impact the efficient functioning of the water management system.

Discourses of culture and illness in South African mental health care and indigenous healing, Part I: Western psychiatric power.

PubMed

Yen, Jeffery; Wilbraham, Lindy

2003-12-01

This discourse analytic study explores constructions of culture and illness in the talk of psychiatrists, psychologists and indigenous healers as they discuss possibilities for collaboration in South African mental health care. Versions of 'culture', and disputes over what constitutes 'disorder', are an important site for the negotiation of power relations between mental health practitioners and indigenous healers. The results of this study are presented in two parts. Part I explores discourses about western psychiatric/psychological professionalism, tensions in diagnosis between cultural relativism and psychiatric universalism, and how assertion of 'cultural differences' may be used to resist psychiatric power. Part II explores how discursive constructions of 'African culture' and 'African madness' work to marginalize indigenous healing in South African mental health care, despite repeated calls for collaboration.

Coherent parity check (CPC) codes are a new framework for the construction of quantum error correction codes that encode multiple qubits per logical block. CPC codes have a canonical structure involving successive rounds of bit and phase parity checks, supplemented by cross-checks to fix the code distance. In this paper, we provide a detailed introduction to CPC codes using conventional quantum circuit notation. We demonstrate the implementation of a CPC code on real hardware, by designing a [[4, 2, 2

The concatenated Greenberger-Horne-Zeilinger (C-GHZ) state is a new type of multipartite entangled state, which has potential application in future quantum information. In this paper, we propose a protocol of constructing arbitrary C-GHZ entangled state approximatively. Different from previous protocols, each logic qubit is encoded in the coherent state. This protocol is based on the linear optics, which is feasible in experimental technology. This protocol may be useful in quantum information based on the C-GHZ state.

We show that we can construct representations with an infinite number of degrees of freedom on compact manifolds. We also show that these representations break translation symmetry. Since such representations can be regarded as quantum gravitational systems with an infinite number of fundamental pre-geometric building blocks, they may be more suitable for the description of effective geometrical phases of the theory.

The prevalence of mental health problems among children and adolescents in Western countries is high. Belgium, like many other Western countries, struggles with the set-up of a coherent and effective strategy for dealing with this complex societal problem. This paper describes the development of a policy scenario for the organization of child and adolescent mental health care services (CAMHS) in Belgium. The development process relied on Soft Systems Methodology including a participatory process with 66 stakeholders and a review of the existing (inter-)national evidence. A diagnostic analysis illustrated that the Belgian CAMHS is a system in serious trouble characterized by fragmentation and compartmentalization. A set of 10 strategic recommendations was formulated to lay down the contours of a future, more effective CAMHS system. They focus on mastering the demands made on scarce and expensive specialized mental health services; strengthening the range of services - in particular for those with serious, complex and multiple mental health problems - and strengthening the adaptive capacity of and the ethical guidance within the future CAMHS system.

Self-efficacy for social participation (SESP) of people with mental illness was examined in urban areas of Japan and China. The subjects were 266 people (140 Japanese, 126 Chinese) with mental illness who were living in their local community. Our SESP scale (SESP27) and the Rosenberg Self-Esteem Scale, Norbeck Social Support Questionnaire (NSSQ), Sense of Coherence measure (SOC13), General Health Questionnaire (GHQ12), and a self-administered questionnaire related to living conditions were used for data collection. Data were analyzed descriptively, correlations between scales were examined, and multiple regression analysis was performed by country. The results showed that annual income was related to SESP in Japan and China. Therefore, improvement of welfare and employment support for economic independence is likely to improve SESP of people with mental illness in both countries. In addition, SESP in people with mental illness is affected by self-esteem in Japan, and coping skills such as improvement of life functions in China. Thus, SESP is affected differently by the social, cultural and institutional characteristics of each country. Copyright © 2016 Elsevier Inc. All rights reserved.

The organization of the brain functional network is associated with mental fatigue, but little is known about the brain network topology that is modulated by the mental fatigue. In this study, we used the graph theory approach to investigate reconfiguration changes in functional networks of different electroen-cephalography (EEG) bands from 16 subjects performing a simulated driving task. Behavior and brain functional networks were compared between the normal and driving mental fatigue states. The scores of subjective self-reports indicated that 90 min of simulated driving-induced mental fatigue. We observed that coherence was significantly increased in the frontal, central, and temporal brain regions. Furthermore, in the brain network topology metric, significant increases were observed in the clustering coefficient (Cp) for beta, alpha, and delta bands and the character path length (Lp) for all EEG bands. The normalized measures γ showed significant increases in beta, alpha, and delta bands, and λ showed similar patterns in beta and theta bands. These results indicate that functional network topology can shift the network topology structure toward a more economic but less efficient configuration, which suggests low wiring costs in functional networks and disruption of the effective interactions between and across cortical regions during mental fatigue states. Graph theory analysis might be a useful tool for further understanding the neural mechanisms of driving mental fatigue.

2015-06-01

The objective of this study was to investigate the effects of long-time commuting and long-hour working on lifestyle including sleeping, physical exercise, breakfast, smoking, alcohol intake and mental health. In this cross-sectional study, data were collected from 146 school teachers in Tokyo. The binary associations of commuting time and working hours with lifestyle, mental stress measured by the General Health Questionnaire (GHQ) and stress coping measured by the Sense of Coherence (SOC) scores were examined. The Chi-square test was used for statistical analyses. Our results indicated that the mean commuting time and working hours per week of the respondents were 42.1 (SD 22.5) minutes and 50.4 (SD 8.6) hours, respectively. Longer commuting time was significantly associated with shorter working hours (p = 0.023), less physical exercise (p < 0.001) and shorter sleeping hours (p = 0.001). Longer working hours were significantly associated with more frequent working on holidays (p = 0.001), higher SOC scores (p = 0.001) and more smoking (p = 0.028). The negative association between GHQ and SOC scores was also significant (p < 0.001). Our findings revealed that long-time commuters were more likely to sleep less, exercise less and work less long. Long-hour workers were more likely to commute shorter, work on holidays more frequently, smoke more and their stress coping potentials were higher. Some kinds of strategies are required to improve the healthy lifestyle for long-time com- muters or long-hour workers.

Relationship between work-family conflict and a sense of coherence among Japanese registered nurses.

PubMed

Takeuchi, Tomoko; Yamazaki, Yoshihiko

2010-12-01

Work-family conflict (WFC) refers to the conflict that arises between a person's work and family life. Previous studies have reported workload, job demands, and irregular working shifts as related to the WFC among nurses and have clarified that WFC is a predictor of job satisfaction, morale, and turnover intention. Very few studies have investigated WFC among Japanese nurses and no study has taken into consideration the sense of coherence (SOC) that helps nurses to cope with stress. The present study aimed to determine the relationship between WFC and SOC and to clarify how WFC and a SOC influence the mental and physical health of nurses in order to suggest ways of establishing work environments that enable nurses to achieve a balance between their work and family life. A self-report questionnaire survey of 388 Japanese female nurses was conducted. The data from 138 nurses who were a mother and/or wife were analyzed. Work-family conflict was significantly related to the SOC. It had a larger impact on the physical and mental health of nurses than their work and family characteristics. The SOC also had a major influence on the physical and mental health of nurses, while having a buffering effect on WFC with respect to depression. Our findings underscore the importance of taking organizational steps to create work environments that contribute to an enhanced SOC in order to reduce the WFC among nurses. © 2010 The Authors.

[Reflections on physical spaces and mental spaces].

PubMed

Chen, Hung-Yi

2013-08-01

This article analyzes certain reciprocal impacts from physical spaces to mental spaces. If the epistemological construction and the spatial imagination from the subject of cogito or the social collectivities are able to influence the construction and creation of the physical spaces of that subject, then the context of that physical space may also affect the cognitive or social subject's mental cognition. This article applies the methodology of iconology from art history (E. Panofsky) and sociology (P. Bourdieu) to explore correlations between the creation of imaginative and physical spaces from the collective consciousness and mental cognition. The author uses Gilles Deleuses's opinion regarding the 17th-century Baroque style and contemporary social collective symptoms as an explanation. From these theoretical studies, the author analyzes the differences of spatial epistemology generated by Taiwan's special geological text. Finally, the author applies Michel Foucault's studies on spatial context to assess the possible application of this thesis of reciprocal impacts from mental spaces to physical spaces in a nursing context.

Stereotypical thinking as a mediating factor in the association between exposure to terror and post-traumatic stress disorder symptoms among Israeli youth.

2016-11-01

The negative impact of exposure to terror on mental health, as well as on the perceptions of each side of the conflict toward the other, is well-documented. However, the association between stereotyping, concomitant with perceived threat, and anxiety, was rarely investigated. The current study examined information processing attributes and exposure to terror as predictors of PTSD symptoms among youth at inter-group conflict, with stereotypical thinking toward a threatening out-group as a possible mediator. Cross-sectional, with exposure to terror, need for cognitive structure (NCS), efficacy at fulfilling the need for closure (EFNC) and self-esteem, predicting stereotypical thinking and PTSD symptoms. Ninth graders (N = 263) from two residential areas in Israel, varying in their degree of exposure to terror, responded to a self-report questionnaire tapping the above variables. Stereotypical thinking was found to mediate the association between exposure to terror and PTSD symptoms, but not the association between the NCS and EFNC interaction and PTSD symptoms. The findings support terror management theory, so that a negative and rigid perception makes it difficult to construct coherent world-view, thus contributing to aggregation of existential anxiety and PTSD symptoms.

Stability of biological father presence as a proxy for family stability: cross-racial associations with the longitudinal development of emotion regulation in toddlerhood.

2014-01-01

The current study, utilizing data from the National Early Head Start Research and Evaluation Project (Love et al., 2005) explored the relationship between biological father presence and emotion regulation over toddlerhood among children from low-income families. Conceptualizing biological father presence as a proxy for family role development, results are interpreted from a role development theoretical perspective. The latent growth curve model was compared based on child ethnoracial status (African American, Caucasian, Hispanic) and child gender. Consistent biological father presence was associated with toddlers' regulatory development across toddlerhood, and this relationship was most robust among Caucasian toddlers as compared to African American toddlers. Findings for Hispanic toddlers were not significantly different from those of Caucasian or African American families. Results bolster the literature on father presence and child outcomes. Analyses address consistency in father presence as a proxy for coherent role development and define a link between consistent father presence and children's regulatory development, demonstrating ethnoracial differences which are likely attributed to the social construction of family roles. © 2014 Michigan Association for Infant Mental Health.

What do we know about promoting mental health through schools?

PubMed

Weare, Katherine; Markham, Wolfgang

2005-01-01

There is a growing evidence base on what schools need to do to promote mental health effectively. There is strong evidence that they need first and foremost to use a whole school approach. This shapes the social contexts which promote mental health and which provide a backdrop of measures to prevent mental health disorders. In this context the targeting of those with particular needs and the work of the specialist services can be much more effective. Schools need to use positive models of mental health, which emphasise well being and competence not just illness--this will help overcome problems of stigma and denial and promote the idea of mental health as 'everyone's business'. The most effective programmes in schools which address mental health have the following characteristics: They provide a backdrop of universal provision to promote the mental health of all and then target those with special needs effectively. They are multi-dimensional and coherent. They create supportive climates that promote warmth, empathy, positive expectations and clear boundaries. They tackle mental health problems early when they first manifest themselves and then take a long term, developmental approach which does not expect immediate answers. They identify and target vulnerable and at risk groups and help people to acquire the skills and competences that underlie mental health. They involve end users and their families in ways that encourage a feeling of ownership and participation, and provide effective training for those who run the programmes, including helping them to promote their own mental health. Using these starting points, we need to develop a rigorous evidence-based approach on this issue. We also require the facilitation of the dissemination of such research findings while encouraging new and innovative approaches.

Cultural competence is an essential component in rendering effective and culturally responsive services to culturally and ethnically diverse clients. Still, great difficulty exists in assessing the cultural competence of mental health nurses. There are no Portuguese validated measurement instruments to assess cultural competence in mental health nurses. This paper reports a study testing the reliability and validity of the Portuguese version of the Multicultural Mental Health Awareness Scale-MMHAS in a sample of Portuguese nurses. Following a standard forward/backward translation into Portuguese, the adapted version of MMHAS, along with a sociodemographic questionnaire, were applied to a sample of 306 Portuguese nurses (299 males, 77 females; ages 21-68 years, M = 35.43, SD = 9.85 years). A psychometric research design was used with content and construct validity and reliability. Reliability was assessed using internal consistency and item-total correlations. Construct validity was determined using factor analysis. The factor analysis confirmed that the Portuguese version of MMHAS has a three-factor structure of multicultural competencies (Awareness, Knowledge, and Skills) explaining 59.51% of the total variance. Strong content validity and reliability correlations were demonstrated. The Portuguese version of MMHAS has a strong internal consistency, with a Cronbach's alpha of 0.958 for the total scale. The results supported the construct validity and reliability of the Portuguese version of MMHAS, proving that is a reliable and valid measure of multicultural counselling competencies in mental health nursing. The MMHAS Portuguese version can be used to evaluate the effectiveness of multicultural competency training programs in Portuguese-speaking mental health nurses. The scale can also be a useful in future studies of multicultural competencies in Portuguese-speaking nurses.

Parisien, Manon; Nour, Kareen; Belley, Anne-Marie; Aubin, Ginette; Billette, Véronique; Dallaire, Bernadette

Objectives A significant proportion of Quebec seniors are living with mental health problems or psychosocial issues such as isolation, bereavement, and psychological distress. These people face many forms of exclusion and are likely to have limited social participation. This paper describes the co-construction steps of a program aimed at promoting community participation among this population.Methods A method for the co-construction of innovative practices in health promotion was used to develop a program that is relevant, rigorous and feasible in diverse settings. The process included several steps, notably: need analysis among seniors and practitioners, development of a logical model for the program, preparation of the leader's manual, validation of the manual by experts, and pilot testing of the program among groups of seniors.Results The goal of the Count me in! program is to promote utilization of the resources of the community that can provide seniors living with mental health conditions or psychosocial issues with activities and positive social contact. The intervention is based on the Strength Model. It includes an individual interview, an eight-meeting workshop, visits to community resources, and collective production of media communication.Conclusion A co-construction process allowed the program to be continuously adjusted in response to stakeholders' feedback. The most important lever for the co-construction was the reconciliation of the partners' practical, conceptual, and experiential expertise. However, contextual factors such as the organization and the availability of mental health services for seniors constituted important barriers to the process.

Exploring the Needs, Expectations, and Realities of Mental Healthcare for Transgender Adults: A Grounded Theory Study on Experiences in Sweden

PubMed Central

Carroll-Beight, Debra; Larsson, Markus

2018-01-01

Abstract Purpose: Transgender persons experience a disproportionate representation in adverse mental health conditions globally. In Sweden, there are tangible efforts to improve mental healthcare overall, but transgender persons still struggle with meeting their mental healthcare needs and there is an absence of understanding the role of mental healthcare for this population and how services are being utilized. Thus, the aim of this study was to gain knowledge from transgender individuals in Sweden concerning their mental healthcare, their needs, expectations, and realities, regardless of transition status. Methods: Eleven in-depth interviews were conducted with persons who identified as transgender, older than 18 years, at some stage of transition in Sweden. Data were collected, analyzed, and interpreted using constructivist ground theory. Results: Three categories emerged from the analysis, Feeling Objectification Rather than Subjectivity, Constructing the Narrative, and Reflecting on Aspects of Care that illustrate the dual tensions at play in transgender visibility, communication with mental healthcare professionals, and expectations of care. Six subcategories further delineate the specific forces at work that construct the mental healthcare experiences for trans persons. Conclusion: Increased knowledge and visibility of transgender persons are needed to adequately serve the mental healthcare needs for this population. Currently, there are barriers that inhibit transgender persons from getting the mental healthcare assistance desired and needed, as they do not view the healthcare system as safe space. As steps are being taken to depathologize transgender identities, momentum should be continued to create space for trans persons that enables unencumbered mental health assistance. PMID:29806033

Conceptual coherence of non-Newtonian worldviews in Force Concept Inventory data

Scott, Terry F.; Schumayer, Dániel

2017-06-01

The Force Concept Inventory is one of the most popular and most analyzed multiple-choice concept tests used to investigate students' understanding of Newtonian mechanics. The correct answers poll a set of underlying Newtonian concepts and the coherence of these underlying concepts has been found in the data. However, this inventory was constructed after several years of research into the common preconceptions held by students and using these preconceptions as distractors in the questions. Their sole purpose is to deflect non-Newtonian candidates away from the correct answer. Alternatively, one can argue that the responses could also be treated as polling these preconceptions. In this paper we shift the emphasis of the analysis away from the correlation structure of the correct answers and look at the latent traits underlying the incorrect responses. Our analysis models the data employing exploratory factor analysis, which uses regularities in the data to suggest the existence of underlying structures in the cognitive processing of the students. This analysis allows us to determine whether the data support the claim that there are alternate non-Newtonian worldviews on which students' incorrect responses are based. The existence of such worldviews, and their coherence, could explain the resilience of non-Newtonian preconceptions and would have significant implications to the design of instruction methods. We find that there are indeed coherent alternate conceptions of the world which can be categorized using the results of the research that led to the construction of the Force Concept Inventory.

Scanning of speechless comics changes spatial biases in mental model construction.

PubMed

Román, Antonio; Flumini, Andrea; Santiago, Julio

2018-08-05

The mental representation of both time and number shows lateral spatial biases, which can be affected by habitual reading and writing direction. However, this effect is in place before children begin to read. One potential early cause is the experiences of looking at picture books together with a carer, as those images also follow the directionality of the script. What is the underlying mechanism for this effect? In the present study, we test the possibility that such experiences induce spatial biases in mental model construction, a mechanism which is a good candidate to induce the biases observed with numbers and times. We presented a speechless comic in either standard (left-to-right) or mirror-reversed (right-to-left) form to adult Spanish participants. We then asked them to draw the scene depicted by sentences like 'the square is between the cross and the circle'. The position of the lateral objects in these drawings reveals the spatial biases at work when building mental models in working memory. Under conditions of highly consistent directionality, the mirror comic changed pre-existing lateral biases. Processes of mental model construction in working memory stand as a potential mechanism for the generation of spatial biases for time and number.This article is part of the theme issue 'Varieties of abstract concepts: development, use and representation in the brain'. © 2018 The Author(s).

High levels of self-stigma are associated with a range of adverse mental health, treatment, and functional outcomes. This prospective study examined the effects of an electronic mental health stigma reduction intervention on self-stigma (self-blame, shame, and help-seeking inhibition) among male construction workers in Australia. Male construction workers (N = 682) were randomly assigned to receive either the intervention condition or the wait list control over a six-week period. Self-stigma was assessed using the Self-Stigma of Depression Scale at post-intervention. We conducted linear regression to assess the effectiveness of the intervention on self-stigma, adjusting for relevant covariates. Self-stigma was relatively low in the sample. The intervention had no significant effect on self-stigma, after adjusting for confounders. There were reductions in stigma in both the intervention and control groups at 6-week follow-up. Process evaluation indicated that participants generally enjoyed the program and felt that it was beneficial to their mental health. These observations underscore the need for further research to elucidate understanding of the experience of self-stigma among employed males.

Boezeman, Edwin J; Nieuwenhuijsen, Karen; Sluiter, Judith K

2016-05-25

To test the predictive value and convergent construct validity of a 6-item work functioning screener (WFS-H). Healthcare workers (249 nurses) completed a questionnaire containing the work functioning screener (WFS-H) and a work functioning instrument (NWFQ) measuring the following: cognitive aspects of task execution and general incidents, avoidance behavior, conflicts and irritation with colleagues, impaired contact with patients and their family, and level of energy and motivation. Productivity and mental health were also measured. Negative and positive predictive values, AUC values, and sensitivity and specificity were calculated to examine the predictive value of the screener. Correlation analysis was used to examine the construct validity. The screener had good predictive value, since the results showed that a negative screener score is a strong indicator of work functioning not hindered by mental health problems (negative predictive values: 94%-98%; positive predictive values: 21%-36%; AUC:.64-.82; sensitivity: 42%-76%; and specificity 85%-87%). The screener has good construct validity due to moderate, but significant (p<.001), associations with productivity (r=.51), mental health (r=.48), and distress (r=.47). The screener (WFS-H) had good predictive value and good construct validity. Its score offers occupational health professionals a helpful preliminary insight into the work functioning of healthcare workers.

The aim of the present study was to investigate sense of coherence in healthy siblings of persons suffering from schizophrenia as well as their ways of coping in the relationship with ill brother or sister. 40 healthy brothers and sisters of persons with ICD- 10 diagnosis of F20 to F29 participated in the present study. Orientation to Life Scale (SOC- 29) was used to assess sense of coherence and Ways of Coping with Stress questionnaire (SRSS) was used to examine stress coping strategies. Mean global score of siblings of persons with schizophrenia was 111 points. Subjects used coping strategies focused on problem significantly more often than those focused on emotions. Therapeutic work with healthy siblings should focus on strengthening sense of personal competence, development of personal resources and different ways of coping with stress, investigation of emotions that healthy siblings experience in the relationship with ill brother or sister as well as supporting the process of accepting changes in the relationship with the ill sibling.

Depression and anxiety are the most common mental symptoms in patients with thyroid cancer (DTC) and have an important influence on the quality of life. The aim of the current study was to identify protective factors of depression and anxiety in DTC patients. In a cross-sectional study 230 DTC patients were examined with Hospital Anxiety and Depression Scale (HADS-D), the Sense of Coherence Scale (SOC-13) and the Questionnaire of Social Support (F-SOZU). Depression correlated highly significantly with anxiety (r = .633, p = 0,001). Social support and sense of coherence correlated highly significantly negative with depression as well as with anxiety (both p < or = 0,001). Although still significant, the correlation between age and anxiety was lower (r = -.19; p < or = 0,005). The TSH level as an indicator of hypothyreodism did not correlate with depression or with anxiety on a significant statistical level. Furthermore, variables such as education, religiosity and elapsed time interval since initial diagnosis were not correlated with depression and anxiety. Our results support the thesis that low social support and low sense of coherence enhance vulnerability to depressive and anxiety symptoms.

Is the mental wellbeing of young Australians best represented by a single, multidimensional or bifactor model?

Internationally there is a growing interest in the mental wellbeing of young people. However, it is unclear whether mental wellbeing is best conceptualized as a general wellbeing factor or a multidimensional construct. This paper investigated whether mental wellbeing, measured by the Mental Health Continuum-Short Form (MHC-SF), is best represented by: (1) a single-factor general model; (2) a three-factor multidimensional model or (3) a combination of both (bifactor model). 2220 young Australians aged between 16 and 25 years completed an online survey including the MHC-SF and a range of other wellbeing and mental ill-health measures. Exploratory factor analysis supported a bifactor solution, comprised of a general wellbeing factor, and specific group factors of psychological, social and emotional wellbeing. Confirmatory factor analysis indicated that the bifactor model had a better fit than competing single and three-factor models. The MHC-SF total score was more strongly associated with other wellbeing and mental ill-health measures than the social, emotional or psychological subscale scores. Findings indicate that the mental wellbeing of young people is best conceptualized as an overarching latent construct (general wellbeing) to which emotional, social and psychological domains contribute. The MHC-SF total score is a valid and reliable measure of this general wellbeing factor. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

This study investigated the incidence of mental harm due to occupational accidents and the relation between psychosocial factors at work and the occurrence of occupational accidents in the Netherlands for the construction industry and health and welfare sector. Analyses revealed that occupational accidents in the construction industry more often involved physical harm, whereas accidents in the health and welfare sector relatively more often resulted in mental harm, in comparison to other sectors. Results showed that psychosocial factors were associated with occupational accidents in both sectors. For the construction industry, high time pressure and exposure to violence and harassment by colleagues or supervisors were associated with occupational accidents. For the health and welfare sector, low autonomy and exposure to violence and harassment by colleagues or supervisors or by people outside the organization were associated with occupational accidents. The present paper stresses the importance of also taking psychological consequences and psychosocial factors at work into account in assessing the occurrence of occupational accidents.

Uncontrollable behavior or mental illness? Exploring constructions of bulimia using Q methodology.

2014-01-01

In medical and psychological literature bulimia is commonly described as a mental illness. However, from a social constructionist perspective the meaning of bulimia will always be socially and historically situated and multiple. Thus, there is always the possibility for other understandings or constructions of bulimia to circulate in our culture, with each having distinct real-world implications for those engaging in bulimic behaviors; for instance, they might potentially influence likelihood of help-seeking and the success of treatment. This study used Q methodology to explore culturally-available constructions of bulimia nervosa. Seventy-seven adults with varying experience of eating disorders took part in this Q methodological study. Online, they were asked to rank-order 42 statements about bulimia, and then answer a series of questions about the task and their knowledge of bulimia. A by-person factor analysis was then conducted, with factors extracted using the centroid technique and a varimax rotation. Six factors satisfied selection criteria and were subsequently interpreted. Factor A, "bulimia as uncontrolled behavior", positions bulimia as a behavioral rather than psychological issue. Factor B, entitled "bulimia is a distressing mental illness", reflects an understanding of bulimic behaviors as a dysfunctional coping mechanism, which is often found in psychological literature. Other perspectives position bulimia as about "self-medicating with food" (Factor C), "the pathological pursuit of thinness" (Factor D), "being the best at being thin" (Factor E), or as "extreme behavior vs. mentally ill" (Factor F). These constructions have distinct implications for the subjective experience and behavior of those engaged in bulimic behaviors, with some constructions possibly being more useful in terms of help-seeking (Factor B), while others position these individuals in ways that may be distressing, for instance as shallow (Factor D) or to blame (Factor E). This study has identified a range of distinct constructions of bulimia. These constructions are considered to have implications for the behaviors and experiences of those engaging in bulimic behaviors. As such, further research into constructions of bulimia may illuminate factors that influence help-seeking and the self-perceptions of such individuals.

We show that the (2+1)-dimensional Dirac-Moshinsky oscillator coupled to an external magnetic field can be treated algebraically with the SU(1,1) group theory and its group basis. We use the su(1,1) irreducible representation theory to find the energy spectrum and the eigenfunctions. Also, with the su(1,1) group basis we construct the relativistic coherent states in a closed form for this problem.

Optical rogue waves of the coupled nonlinear Schrödinger equations with negative coherent coupling, which describe the propagation of orthogonally polarized optical waves in an isotropic medium, are reported. We construct and discuss a family of the vector rogue-wave solutions, including the bright rogue waves, four-petaled rogue waves, and dark rogue waves. A bright rogue wave without a valley can split up, giving birth to two bright rogue waves, and an eye-shaped rogue wave can split up, giving birth to two dark rogue waves.

The fast dephasing of electron spins in an ensemble of quantum dots is detrimental for applications in quantum information processing. We show here that dephasing can be overcome by using a periodic train of light pulses to synchronize the phases of the precessing spins, and we demonstrate this effect in an ensemble of singly charged (In,Ga)As/GaAs quantum dots. This mode locking leads to constructive interference of contributions to Faraday rotation and presents potential applications based on robust quantum coherence within an ensemble of dots.

Here, the coherent discrete variable representation (ZDVR) has been extended for construct- ing a multidimensional potential-optimized DVR basis on a sphere. In order to deal with the non-constant Jacobian in spherical angles, two direct product primitive basis methods are proposed so that the original ZDVR technique can be properly implemented. The method has been demonstrated by computing the lowest states of a two dimensional (2D) vibrational model. Results show that the extended ZDVR method gives accurate eigenval- ues and exponential convergence with increasing ZDVR basis size.

We investigate a nonlinear coherent feedback circuit constructed from preexisting superconducting microwave devices. The network exhibits emergent bistable and astable states, and we demonstrate its operation as a latch and the frequency locking of its oscillations. While the network is tedious to model by hand, our observations agree quite well with the semiclassical dynamical model produced by a new software package (N. Tezak , arXiv:1111.3081v1 [Phil. Trans. R. Soc. A (to be published)]) that systematically interpreted an idealized schematic of the system as a quantum optic feedback network.

Elementary derivation of the quantum propagator for the harmonic oscillator

NASA Astrophysics Data System (ADS)

Shao, Jiushu

2016-10-01

Operator algebra techniques are employed to derive the quantum evolution operator for the harmonic oscillator. The derivation begins with the construction of the annihilation and creation operators and the determination of the wave function for the coherent state as well as its time-dependent evolution, and ends with the transformation of the propagator in a mixed position-coherent-state representation to the desired one in configuration space. Throughout the entire procedure, besides elementary operator manipulations, it is only necessary to solve linear differential equations and to calculate Gaussian integrals.

"A Geography of Disparate Spirits": Pathology as Oppression in "A Woman is Talking to Death" and "Mental".

2015-01-01

This article foregrounds Judy Grahn's commitment to social justice and chiefly considers her nine-part poems: "A Woman is Talking to Death" and "Mental." These poems illuminate the socially constructed nature of mental illness and challenge readers to consider how and why the characters within them are deemed mentally ill. Little, if any, scholarship has been devoted to using Grahn's poetry, and particularly "Mental," as a framework for analyzing the pathologization of people, especially women, relative to the system of mental health. Her work remains relevant to critical conversations that illuminate contemporary issues of oppression that still haunt us today.

How Do Thoughts, Emotions, and Decisions Align? A New Way to Examine Theory of Mind in Middle Childhood and Beyond

PubMed Central

Lagattuta, Kristin Hansen

2016-01-01

The current study examined 4- to 10-year-olds’ and adults’ (N = 280) tendency to connect people’s thoughts, emotions, and decisions into valence-matched mental state triads (thought valence = emotion valence = decision valence; such as, anticipate something bad + feel worried + avoid) and valence-matched mental state dyads (thought-emotion, thought-decision, and emotion-decision). Participants heard vignettes about focal characters who re-encountered individuals who had previously harmed them twice, helped them twice, or both harmed and helped them. Baseline trials involved no past experience. Children and adults predicted the focal characters’ thoughts (anticipate something good or bad), emotions (feel happy or worried), and decisions (go near or stay away). Results showed significant increases between 4 and 10 years in the formation of valence-matched mental state triads and dyads, with thoughts and emotions most often aligned by valence. We also documented age-related improvement in awareness that uncertain situations elicit less valence-consistent mental states than more certain situations, with females expecting weaker coherence among characters’ thoughts, emotions, and decisions than males. Controlling for age and sex, individuals with stronger executive function (working memory and inhibitory control) predicted more valence-aligned mental states. These findings add to the emerging literature on development and individual differences in children’s reasoning about mental states and emotions during middle childhood and beyond. PMID:27017060

To determine the relationships between different sense of coherence levels and quality of life, and in older female myocardial infarction survivors; to investigate how socio-demographic, clinical characteristics, sense of coherence self-reported symptoms and function affect quality of life; and to determine whether sense of coherence and quality of life are stable during a six-month follow-up. Myocardial infraction confers new physical and mental challenges. However, research on sense of coherence and other factors involved in maintaining physical, psychosocial and environmental aspects of quality of life in older female myocardial infraction survivors is scant. Survey. A postal survey was conducted of 145 women, aged 62-80 years, three months to five years after myocardial infarction (T1), with a follow-up after six months (T2). Self-reported socio-demographic and clinical data and hospital medical records data were collected. The sense of coherence scale (SOC-29) and the World Health Organization Quality of Life Instrument Abbreviated (WHOQOL-BREF) were used. We found a significant difference in quality of life between weak, moderate, and strong sense of coherence groups (p<0.001). Sense of coherence contributed to the level of all quality of life domains (p<0.001). Several clinical characteristics contributed to quality of life: (1) physical domain: comorbidities (p<0.001), previous myocardial infarction (p = 0.013), ejection fraction (p<0.011), length of hospital stay (p = 0.005) symptoms and function (p<0.001); (2) psychological domain: previous myocardial infarction (p = 0.031) and symptoms and function (p<0.001); and (3) environmental domain: education (p = 0.033) and symptoms and function (p = 0.003). On group level, both sense of coherence and quality of life were stable. Experiencing specific health changes (p<0.001), not major life events, influenced quality of life during the six-month follow-up. Sense of coherence was an important stable determinant of quality of life domains in female myocardial infarction survivors. Although other factors were identified, further research is needed to elucidate additional determinants of quality of life. These specific factors could guide clinicians in making treatment decisions that optimize the quality of life of their patients. Applying a salutogenic perspective through patient education may be important.

Disentangling self-stigma: are mental illness and help-seeking self-stigmas different?

PubMed

2013-10-01

Two established but disparate lines of research exist: studies examining the self-stigma associated with mental illness and studies examining the self-stigma associated with seeking psychological help. Whereas some researchers have implicitly treated these 2 constructs as synonymous, others have made the argument that they are theoretically and empirically distinct. To help clarify this debate, we examined in the present investigation the overlap and uniqueness of the self-stigmas associated with mental illness and with seeking psychological help. Data were collected from a sample of college undergraduates experiencing clinical levels of psychological distress (N = 217) and a second sample of community members with a self-reported history of mental illness (N = 324). Confirmatory factor analyses provide strong evidence for the factorial independence of the 2 types of self-stigma. Additionally, results of regression analyses in both samples suggest that the 2 self-stigmas uniquely predict variations in stigma-related constructs (i.e., shame, self-blame, and social inadequacy) and attitudes and intentions to seek help. Implications for researchers and clinicians interested in understanding stigma and enhancing mental health service utilization are discussed.

We demonstrate optical coherence transfer of subhertz-linewidth laser light through fiber links by actively compensating random fiber phase noise induced by environmental perturbations. The relative linewidth of laser light after transferring through a 32-km urban fiber link is suppressed within 1 mHz (resolution bandwidth limited), and the absolute linewidth of the transferred laser light is less than 0.36 Hz. For an 82-km fiber link, a repeater station is constructed between a 32-km urban fiber and a 50-km spooled fiber to recover the spectral purity. A relative linewidth of 1 mHz is also demonstrated for light transferring through the 82-km cascaded fiber. Such an optical signal distribution network based on repeater stations allows optical coherence and synchronization available over spatially separated places.

We examine mathematical questions around angle (or phase) operator associated with a number operator through a short list of basic requirements. We implement three methods of construction of quantum angle. The first one is based on operator theory and parallels the definition of angle for the upper half-circle through its cosine and completed by a sign inversion. The two other methods are integral quantization generalizing in a certain sense the Berezin–Klauder approaches. One method pertains to Weyl–Heisenberg integral quantization of the plane viewed as the phase space of the motion on the line. It depends on a family of “weight”more » functions on the plane. The third method rests upon coherent state quantization of the cylinder viewed as the phase space of the motion on the circle. The construction of these coherent states depends on a family of probability distributions on the line.« less

(The feeling of) meaning-as-information.

PubMed

Heintzelman, Samantha J; King, Laura A

2014-05-01

The desire for meaning is recognized as a central human motive. Yet, knowing that people want meaning does not explain its function. What adaptive problem does this experience solve? Drawing on the feelings-as-information hypothesis, we propose that the feeling of meaning provides information about the presence of reliable patterns and coherence in the environment, information that is not provided by affect. We review research demonstrating that manipulations of stimulus coherence influence subjective reports of meaning in life but not affect. We demonstrate that manipulations that foster an associative mindset enhance meaning. The meaning-as-information perspective embeds meaning in a network of foundational functions including associative learning, perception, cognition, and neural processing. This approach challenges assumptions about meaning, including its motivational appeal, the roles of expectancies and novelty in this experience, and the notion that meaning is inherently constructed. Implications for constructed meaning and existential meanings are discussed.

Mental Health Literacy in Young Adults: Adaptation and Psychometric Properties of the Mental Health Literacy Questionnaire.

Dias, Pedro; Campos, Luísa; Almeida, Helena; Palha, Filipa

2018-06-23

Mental health literacy (MHL) is considered a prerequisite for early recognition and intervention in mental disorders, and for this reason, it has become a focus of research over the past few decades. Assessing this construct is relevant for identifying knowledge gaps and erroneous beliefs concerning mental health issues, to inform the development of interventions aimed at promoting mental health literacy as well as the evaluation of these interventions. Recently, we developed a new self-reporting measure (MHLq) for assessing mental health literacy in young people (12⁻14 years-old), meeting the need to assess MHL from a comprehensive perspective of the construct instead of focusing on a restricted number of mental disorders or specific dimensions (e.g., knowledge concerning specific disorders; stigma). The present study aimed to adapt the MHLq for the young adult population and to examine its psychometric properties, according to the following steps: (1) item adaptation, using a think aloud procedure (n = 5); (2) data collection (n = 356, aged between 18 and 25 years old; and (3) psychometric analyses (exploratory factor analysis and internal consistency analysis). The final version of the questionnaire included 29 items (total scale α = 0.84), organized by four dimensions: (1) knowledge of mental health problems (α = 0.74); (2) erroneous beliefs/stereotypes (α = 0.72); (3) help-seeking and first aid skills (α = 0.71); and (4) self-help strategies (α = 0.60). The results suggest that the MHLq-adult form is a practical, valid, and reliable screening tool for identifying gaps in knowledge, beliefs, and behavioral intentions related to mental health and mental disorders, planning promotion programs, and evaluating intervention effectiveness.

Comparing and Contrasting the Cognitive Effects of Hippocampal and Ventromedial Prefrontal Cortex Damage: A Review of Human Lesion Studies.

McCormick, Cornelia; Ciaramelli, Elisa; De Luca, Flavia; Maguire, Eleanor A

2018-03-15

The hippocampus and ventromedial prefrontal cortex (vmPFC) are closely connected brain regions whose functions are still debated. In order to offer a fresh perspective on understanding the contributions of these two brain regions to cognition, in this review we considered cognitive tasks that usually elicit deficits in hippocampal-damaged patients (e.g., autobiographical memory retrieval), and examined the performance of vmPFC-lesioned patients on these tasks. We then took cognitive tasks where performance is typically compromised following vmPFC damage (e.g., decision making), and looked at how these are affected by hippocampal lesions. Three salient motifs emerged. First, there are surprising gaps in our knowledge about how hippocampal and vmPFC patients perform on tasks typically associated with the other group. Second, while hippocampal or vmPFC damage seems to adversely affect performance on so-called hippocampal tasks, the performance of hippocampal and vmPFC patients clearly diverges on classic vmPFC tasks. Third, although performance appears analogous on hippocampal tasks, on closer inspection, there are significant disparities between hippocampal and vmPFC patients. Based on these findings, we suggest a tentative hierarchical model to explain the functions of the hippocampus and vmPFC. We propose that the vmPFC initiates the construction of mental scenes by coordinating the curation of relevant elements from neocortical areas, which are then funneled into the hippocampus to build a scene. The vmPFC then engages in iterative re-initiation via feedback loops with neocortex and hippocampus to facilitate the flow and integration of the multiple scenes that comprise the coherent unfolding of an extended mental event.

Good social skills despite poor theory of mind: exploring compensation in autism spectrum disorder.

PubMed

Livingston, Lucy Anne; Colvert, Emma; Bolton, Patrick; Happé, Francesca

2018-03-26

It is proposed that some individuals with Autism Spectrum Disorder (ASD) can 'compensate' for their underlying difficulties (e.g. in theory of mind; ToM), thus demonstrating relatively few behavioural symptoms, despite continued core cognitive deficits. The mechanisms underpinning compensation are largely unexplored, as is its potential impact on mental health. This study aimed to estimate compensation patterns in ASD, by contrasting overt social behaviour with ToM task performance, in order to compare the characteristics of 'Low' and 'High' Compensators. A total of 136 autistic adolescents, from the ongoing Social Relationships Study, completed a range of cognitive tasks, the Autistic Diagnostic Observation Schedule (ADOS) and a self-report anxiety questionnaire. Participants were assigned compensation group status; High Compensators demonstrated good ADOS scores despite poor ToM performance, while Low Compensators demonstrated similarly poor ToM, accompanied by poor ADOS scores. High Compensators demonstrated better IQ and executive function (EF), but greater self-reported anxiety, compared with Low Compensators. Such differences were not found when comparing individuals who had good versus poor ADOS scores, when ToM performance was good. Other core autistic characteristics (weak central coherence, nonsocial symptoms) did not differentiate the High and Low Compensators. IQ, EF and anxiety appear to be implicated in the processes by which certain autistic young people can compensate for their underlying ToM difficulties. This tendency to compensate does not appear to reflect the severity of 'hit' for ASD per se, suggesting that well-compensated individuals are not experiencing a milder form of ASD. The construct of compensation in ASD has implications for research and clinical practice. © 2018 The Authors.

The gate fidelity and the coherence time of a quantum bit (qubit) are important benchmarks for quantum computation. We construct a qubit using a single electron spin in an Si/SiGe quantum dot and control it electrically via an artificial spin-orbit field from a micromagnet. We measure an average single-qubit gate fidelity of ~99% using randomized benchmarking, which is consistent with dephasing from the slowly evolving nuclear spins in the substrate. The coherence time measured using dynamical decoupling extends up to ~400 μs for 128 decoupling pulses, with no sign of saturation. We find evidence that the coherence time is limitedmore » by noise in the 10-kHz to 1-MHz range, possibly because charge noise affects the spin via the micromagnet gradient. Furthermore, this work shows that an electron spin in an Si/SiGe quantum dot is a good candidate for quantum information processing as well as for a quantum memory, even without isotopic purification.« less

Generating the Local Oscillator "Locally" in Continuous-Variable Quantum Key Distribution Based on Coherent Detection

NASA Astrophysics Data System (ADS)

Qi, Bing; Lougovski, Pavel; Pooser, Raphael; Grice, Warren; Bobrek, Miljko

2015-10-01

Continuous-variable quantum key distribution (CV-QKD) protocols based on coherent detection have been studied extensively in both theory and experiment. In all the existing implementations of CV-QKD, both the quantum signal and the local oscillator (LO) are generated from the same laser and propagate through the insecure quantum channel. This arrangement may open security loopholes and limit the potential applications of CV-QKD. In this paper, we propose and demonstrate a pilot-aided feedforward data recovery scheme that enables reliable coherent detection using a "locally" generated LO. Using two independent commercial laser sources and a spool of 25-km optical fiber, we construct a coherent communication system. The variance of the phase noise introduced by the proposed scheme is measured to be 0.04 (rad2 ), which is small enough to enable secure key distribution. This technology also opens the door for other quantum communication protocols, such as the recently proposed measurement-device-independent CV-QKD, where independent light sources are employed by different users.

Coherent structure in solar wind C{sup 6+}/C{sup 4+} ionic composition data during the quiet-sun conditions of 2008

This analysis offers evidence of characteristic scale sizes in solar wind charge state data measured in situ for 13 quiet-Sun Carrington rotations in 2008. Using a previously established novel methodology, we analyze the wavelet power spectrum of the charge state ratio C{sup 6+}/C{sup 4+} measured in situ by ACE/SWICS for 2 hr and 12 minute cadence. We construct a statistical significance level in the wavelet power spectrum to quantify the interference effects arising from filling missing data in the time series, allowing extraction of significant power from the measured data to a resolution of 24 minutes. We analyze each waveletmore » power spectrum for transient coherency and global periodicities resulting from the superposition of repeating coherent structures. From the significant wavelet power spectra, we find evidence for a general upper limit on individual transient coherency of ∼10 days. We find evidence for a set of global periodicities between 4-5 hr and 35-45 days. We find evidence for the distribution of individual transient coherency scales consisting of two distinct populations. Below the ∼2 day timescale, the distribution is reasonably approximated by an inverse power law, whereas for scales ≳2 days, the distribution levels off, showing discrete peaks at common coherency scales. In addition, by organizing the transient coherency scale distributions by wind type, we find that these larger, common coherency scales are more prevalent and well defined in coronal hole wind. Finally, we discuss the implications of our results for current theories of solar wind generation and describe future work for determining the relationship between the coherent structures in our ionic composition data and the structure of the coronal magnetic field.« less

What can we learn? Adult outcomes in children of seriously mentally ill mothers.

PubMed

O'Connell, Kathleen LeClear

2008-05-01

Information is lacking about the experiences, needs of, and interventions for children of seriously mentally ill mothers. Quantitative and qualitative methods of inquiry were used to retrospectively explore the characteristics and needs of adult children of seriously mentally ill mothers. The sample (N = 40) was recruited by referral and media advertisements. Childhood variables related to attachment, family environment, and parenting were compared to adult well-being outcomes of depression, quality of life, sense of coherence, and self-esteem. Participants also responded to the question "What other question should have been included in this study about your experience as the child of a seriously mentally ill mother?" and, additionally, spontaneously added their own clarifications of their answers to the survey questions. It was apparent that the childhoods of participants were disruptive and often painful. Over half of the sample reported having their own diagnosis of depression in adulthood. Despite these factors, most members of the study sample were functioning well in adulthood, most often as a result of their own initiative. A high rate of depression in adulthood and participants' own descriptions of their painful memories and experiences of childhood identifies that more can and should be done to assist children of mentally ill mothers to cope with their environments. Interventions at various times in childhood are described.

A systematic review of the literature exploring illness perceptions in mental health utilising the self-regulation model.

PubMed

Baines, Tineke; Wittkowski, Anja

2013-09-01

Psychologists have utilised a range of social cognition models to understand variation in physical health and illness-related behaviours. The most widely studied model of illness perceptions has been the Self-Regulation Model (SRM, Leventhal, Nerenz, & Steele, 1984). The illness perceptions questionnaire (IPQ) and its revised version (IPQ-R) have been utilised to explore illness beliefs in physical health. This review examined 13 quantitative studies, which used the IPQ and IPQ-R in mental health in their exploration of illness perceptions in psychosis, bipolar disorder, eating disorders, depression and adolescents experiencing mood disorders. Across these studies the SRM illness dimensions were largely supported. Mental illnesses were commonly viewed as cyclical and chronic, with serious negative consequences. Perceptions regarding chronicity, controllability and negative consequences were associated with coping and help seeking, while engagement with services and help seeking were also related to illness coherence beliefs. Treatment adherence was linked to beliefs that treatment could control one's illness. Whilst a major limitation of the reviewed studies was the use of cross-sectional designs, overall the applicability of the SRM to mental health was supported. The IPQ and IPQ-R were shown to be valuable measures of illness perceptions in mental health, offering implications for clinical practice.

A Window of Opportunity for the Transformation of National Mental Health Policy in Turkey Following Two Major Earthquakes

PubMed Central

Munir, Kerim; Ergene, Tuncay; Tunaligil, Verda; Erol, Nese

2011-01-01

Striking at the nation’s highly populated industrial heartlands, two massive earthquakes in 1999 killed over 25,000 people in Turkey. The economic cost and the humanitarian magnitude of the disaster were unprecedented in the country’s history. The crisis also underscored a major flaw in the organization of mental health services in the provinces that were left out of the 1961 reforms that aimed to make basic health services available nationwide. In describing the chronology of the earthquakes and the ensuing national and international response, this article explains how the public and governmental experience of the earthquakes has created a window of opportunity, and perhaps the political will, for significant reform. There is an urgent need to integrate mental health and general health services, and to strengthen mental health services in the country’s 81 disparate provinces. As Turkey continues her rapid transformation in terms of greater urbanization, higher levels of public education, and economic and constitutional reforms associated with its projected entry into the European Union, there have also been growing demands for better, and more equitably distributed, health care. A legacy of the earthquakes is that they exposed the need for Turkey to create a coherent, clearly articulated national mental health policy. PMID:15371066

These interventions are associated with elevated rates of addictions and mental health issues among Indigenous peoples. In this paper we employ an indigenized social determinants approach to mental health…

Shared mental models of integrated care: aligning multiple stakeholder perspectives.

Evans, Jenna M; Baker, G Ross

2012-01-01

Health service organizations and professionals are under increasing pressure to work together to deliver integrated patient care. A common understanding of integration strategies may facilitate the delivery of integrated care across inter-organizational and inter-professional boundaries. This paper aims to build a framework for exploring and potentially aligning multiple stakeholder perspectives of systems integration. The authors draw from the literature on shared mental models, strategic management and change, framing, stakeholder management, and systems theory to develop a new construct, Mental Models of Integrated Care (MMIC), which consists of three types of mental models, i.e. integration-task, system-role, and integration-belief. The MMIC construct encompasses many of the known barriers and enablers to integrating care while also providing a comprehensive, theory-based framework of psychological factors that may influence inter-organizational and inter-professional relations. While the existing literature on integration focuses on optimizing structures and processes, the MMIC construct emphasizes the convergence and divergence of stakeholders' knowledge and beliefs, and how these underlying cognitions influence interactions (or lack thereof) across the continuum of care. MMIC may help to: explain what differentiates effective from ineffective integration initiatives; determine system readiness to integrate; diagnose integration problems; and develop interventions for enhancing integrative processes and ultimately the delivery of integrated care. Global interest and ongoing challenges in integrating care underline the need for research on the mental models that characterize the behaviors of actors within health systems; the proposed framework offers a starting point for applying a cognitive perspective to health systems integration.

Quantum bits (qubits) are at the heart of quantum information processing schemes. Currently, solid-state qubits, and in particular the superconducting ones, seem to satisfy the requirements for being the building blocks of viable quantum computers, since they exhibit relatively long coherence times, extremely low dissipation, and scalability. The possibility of achieving quantum coherence in macroscopic circuits comprising Josephson junctions, envisioned by Legett in the 1980's, was demonstrated for the first time in a charge qubit; since then, the exploitation of macroscopic quantum effects in low-capacitance Josephson junction circuits allowed for the realization of several kinds of superconducting qubits. Furthermore, coupling between qubits has been successfully achieved that was followed by the construction of multiple-qubit logic gates and the implementation of several algorithms. Here it is demonstrated that induced qubit lattice coherence as well as two remarkable quantum coherent optical phenomena, i.e., self-induced transparency and Dicke-type superradiance, may occur during light-pulse propagation in quantum metamaterials comprising superconducting charge qubits. The generated qubit lattice pulse forms a compound "quantum breather" that propagates in synchrony with the electromagnetic pulse. The experimental confirmation of such effects in superconducting quantum metamaterials may open a new pathway to potentially powerful quantum computing.

Two-Dimensional DOA and Polarization Estimation for a Mixture of Uncorrelated and Coherent Sources with Sparsely-Distributed Vector Sensor Array

Si, Weijian; Zhao, Pinjiao; Qu, Zhiyu

2016-01-01

This paper presents an L-shaped sparsely-distributed vector sensor (SD-VS) array with four different antenna compositions. With the proposed SD-VS array, a novel two-dimensional (2-D) direction of arrival (DOA) and polarization estimation method is proposed to handle the scenario where uncorrelated and coherent sources coexist. The uncorrelated and coherent sources are separated based on the moduli of the eigenvalues. For the uncorrelated sources, coarse estimates are acquired by extracting the DOA information embedded in the steering vectors from estimated array response matrix of the uncorrelated sources, and they serve as coarse references to disambiguate fine estimates with cyclical ambiguity obtained from the spatial phase factors. For the coherent sources, four Hankel matrices are constructed, with which the coherent sources are resolved in a similar way as for the uncorrelated sources. The proposed SD-VS array requires only two collocated antennas for each vector sensor, thus the mutual coupling effects across the collocated antennas are reduced greatly. Moreover, the inter-sensor spacings are allowed beyond a half-wavelength, which results in an extended array aperture. Simulation results demonstrate the effectiveness and favorable performance of the proposed method. PMID:27258271

Brains striving for coherence: Long-term cumulative plot formation in the default mode network.

Many everyday activities, such as engaging in conversation or listening to a story, require us to sustain attention over a prolonged period of time while integrating and synthesizing complex episodic content into a coherent mental model. Humans are remarkably capable of navigating and keeping track of all the parallel social activities of everyday life even when confronted with interruptions or changes in the environment. However, the underlying cognitive and neurocognitive mechanisms of such long-term integration and profiling of information remain a challenge to neuroscience. While brain activity is generally traceable within the short time frame of working memory (milliseconds to seconds), these integrative processes last for minutes, hours or even days. Here we report two experiments on story comprehension. Experiment I establishes a cognitive dissociation between our comprehension of plot and incidental facts in narratives: when episodic material allows for long-term integration in a coherent plot, we recall fewer factual details. However, when plot formation is challenged, we pay more attention to incidental facts. Experiment II investigates the neural underpinnings of plot formation. Results suggest a central role for the brain's default mode network related to comprehension of coherent narratives while incoherent episodes rather activate the frontoparietal control network. Moreover, an analysis of cortical activity as a function of the cumulative integration of narrative material into a coherent story reveals to linear modulations of right hemisphere posterior temporal and parietal regions. Together these findings point to key neural mechanisms involved in the fundamental human capacity for cumulative plot formation. Copyright © 2015 Elsevier Inc. All rights reserved.

Perception of occupational balance by people with mental illness: A new methodology.

PubMed

Eklund, Mona; Argentzell, Elisabeth

2016-07-01

Aims The aims were to (i) investigate initial construct validity of a tool for assessment of time allocation in occupational balance, and (ii) describe perceived occupational balance and its relationship with socio-demographics, well-being, and personal recovery among people with mental illness. Methods Satisfaction with Daily Occupations and Occupational Balance (SDO-OB) was administered to 226 persons. SDO-OB reflects balance in five occupational domains: work, leisure, home chores, self-care, and overall occupational balance. Indicators for assessing construct validity were: satisfaction with everyday occupations, occupational value, symptom severity, and psychosocial functioning. For the second aim, the data collection included socio-demographics, life quality, self-esteem, self-mastery, and personal recovery. Results Occupational balance ratings indicated the participants were either under-occupied or in balance. Few were over-occupied. Feeling in balance was related to greater well-being and recovery compared with being under-occupied. Risk factors for under-occupation were younger age (in relation to work), and higher education (in relation to overall balance). Conclusions Associations with the indicators suggest initial construct validity. The SDO-OB is promising for assessment of occupational balance among people with mental illness. Being under-occupied was detrimental to well-being and recovery, and this indicates the importance of offering more occupational opportunities for people with mental illness.

Prevention of mental disorders worldwide requires a greater understanding of protective processes associated with lower levels of mental health problems in children who face pervasive life stressors. This study aimed to identify culturally appropriate indicators of individual-level protective factors in Rwandan adolescents where risk factors, namely poverty and a history of trauma, have dramatically shaped youth mental health. The sample included 367 youth aged 10-17 in rural Rwanda. An earlier qualitative study of the same population identified the constructs "kwihangana" (patience/perseverance) and "kwigirira ikizere" (self-esteem) as capturing local perceptions of individual-level characteristics that helped reduce risks of mental health problems in youth. Nine items from the locally derived constructs were combined with 25 items from an existing scale that aligned well with local constructs-the Connor-Davidson Resilience Scale (CD-RISC). We assessed the factor structure of the CD-RISC expanded scale using exploratory factor analysis and determined the correlation of the expanded CD-RISC with depression and functional impairment. The CD-RISC expanded scale displayed high internal consistency (α = 0.93). Six factors emerged, which we labeled: perseverance, adaptability, strength/sociability, active engagement, self-assuredness, and sense of self-worth. Protective factor scale scores were significantly and inversely correlated with depression and functional impairment (r = -0.49 and r = - 0.38, respectively). An adapted scale displayed solid psychometric properties for measuring protective factors in Rwandan youth. Identifying culturally appropriate protective factors is a key component of research associated with the prevention of mental health problems and critical to the development of cross-cultural strength-based interventions for children and families.

A discourse analysis on how service providers in non-medical primary health and social care services understand their roles in mental health care.

Mitchell, Penelope Fay

2009-04-01

Enhancing collaboration between specialist mental health services, primary health care and social care services has been a key priority in mental health policy reform in many countries for about 20 years and remains so. Yet progress in terms of widespread implementation of demonstrably effective models of collaborative care has been slow. The views that different providers hold regarding the parameters of their roles, and the values that guide their approach to service delivery, are likely to exert profound effects on engagement with collaborative initiatives. Little research has explored these issues. In this study, discourse analysis from a structurational perspective was used to explore the views of providers in a diverse purposive sample of non-medical primary health and social care services in the state of Victoria, Australia regarding their mental health care roles. Four interconnected discourses were revealed as supporting role positions constructed in opposition to the putative role positions of specialist mental health services: an informal as opposed to a formal approach; a normalising as opposed to a pathologising approach; holistic social and emotional health and wellbeing, and an individualised or client-focused model of care as opposed to an illness-focused model. These oppositional role constructions may contribute to reluctance among providers in these sectors to engage with some agendas being promoted by specialist mental health services, through either reduced self-efficacy or active resistance to innovations that conflict with strongly held values. Greater awareness of, and critical reflection upon, contrasting role constructions, and the implications of these for practice may facilitate the design of more appropriate collaborative models and stronger commitment to their implementation.

Validation of the Arab Youth Mental Health scale as a screening tool for depression/anxiety in Lebanese children

PubMed Central

2011-01-01

Background Early detection of common mental disorders, such as depression and anxiety, among children and adolescents requires the use of validated, culturally sensitive, and developmentally appropriate screening instruments. The Arab region has a high proportion of youth, yet Arabic-language screening instruments for mental disorders among this age group are virtually absent. Methods We carried out construct and clinical validation on the recently-developed Arab Youth Mental Health (AYMH) scale as a screening tool for depression/anxiety. The scale was administered with 10-14 year old children attending a social service center in Beirut, Lebanon (N = 153). The clinical assessment was conducted by a child and adolescent clinical psychiatrist employing the DSM IV criteria. We tested the scale's sensitivity, specificity, and internal consistency. Results Scale scores were generally significantly associated with how participants responded to standard questions on health, mental health, and happiness, indicating good construct validity. The results revealed that the scale exhibited good internal consistency (Cronbach's alpha = 0.86) and specificity (79%). However, it exhibited moderate sensitivity for girls (71%) and poor sensitivity for boys (50%). Conclusions The AYMH scale is useful as a screening tool for general mental health states and a valid screening instrument for common mental disorders among girls. It is not a valid instrument for detecting depression and anxiety among boys in an Arab culture. PMID:21435213

Causality in Psychiatry: A Hybrid Symptom Network Construct Model

PubMed Central

Young, Gerald

2015-01-01

Causality or etiology in psychiatry is marked by standard biomedical, reductionistic models (symptoms reflect the construct involved) that inform approaches to nosology, or classification, such as in the DSM-5 [Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition; (1)]. However, network approaches to symptom interaction [i.e., symptoms are formative of the construct; e.g., (2), for posttraumatic stress disorder (PTSD)] are being developed that speak to bottom-up processes in mental disorder, in contrast to the typical top-down psychological construct approach. The present article presents a hybrid top-down, bottom-up model of the relationship between symptoms and mental disorder, viewing symptom expression and their causal complex as a reciprocally dynamic system with multiple levels, from lower-order symptoms in interaction to higher-order constructs affecting them. The hybrid model hinges on good understanding of systems theory in which it is embedded, so that the article reviews in depth non-linear dynamical systems theory (NLDST). The article applies the concept of emergent circular causality (3) to symptom development, as well. Conclusions consider that symptoms vary over several dimensions, including: subjectivity; objectivity; conscious motivation effort; and unconscious influences, and the degree to which individual (e.g., meaning) and universal (e.g., causal) processes are involved. The opposition between science and skepticism is a complex one that the article addresses in final comments. PMID:26635639

Mental time travel and the shaping of language.

PubMed

Corballis, Michael C

2009-01-01

Episodic memory can be regarded as part of a more general system, unique to humans, for mental time travel, and the construction of future episodes. This allows more detailed planning than is afforded by the more general mechanisms of instinct, learning, and semantic memory. To be useful, episodic memory need not provide a complete or even a faithful record of past events, and may even be part of a process whereby we construct fictional accounts. The properties of language are aptly designed for the communication and sharing of episodes, and for the telling of stories; these properties include symbolic representation of the elements of real-world events, time markers, and combinatorial rules. Language and mental time travel probably co-evolved during the Pleistocene, when brain size increased dramatically.

Maximising the Opportunity for Healthy Ageing: Online Mental Health Measurement and Targeted Interventions.

Longevity is a valuable resource for society, as older people are increasingly looking for new ways to contribute after retirement. Their contribution is however dependent upon their physical health, mental health and wellbeing. The potential role that mental health and wellbeing, two separate but interrelated constructs, play often are both under-recognised and insufficiently targeted. Positive ageing is a positive and constructive view of ageing, where older people actively work on maintaining a positive attitude, work towards keeping fit and healthy, and strive to maximize their wellbeing. Interventions stimulating positive ageing show promising results for both mental health and wellbeing, and telehealth can play an important role in improving the reach and effectiveness of positive ageing interventions. Telehealth solutions can also help researchers reliably measure and better understand the drivers of wellbeing at individual and population levels; results that can both form the basis for advancing the field of positive ageing and help inform public policy.

Construct Validity of the SF-12v2 for the Homeless Population with Mental Illness: An Instrument to Measure Self-Reported Mental and Physical Health

2016-01-01

Background Self-reported health measures are important indicators used by clinicians and researchers for the evaluation of health interventions, outcome assessment of clinical studies, and identification of health needs to improve resource allocation. However, the application of self-reported health measures relies on developing reliable and valid instruments that are suitable across diverse populations. The main objective of this study is to evaluate the construct validity of the SF-12v.2, an instrument for measuring self-rated physical and mental health, for homeless adults with mental illness. Various interventions have been aimed at improving the health of homeless people with mental illness, and the development of valid instruments to evaluate these interventions is imperative. Study Design We measured self-rated mental and physical health from a quota sample of 575 homeless people with mental illness using the SF-12v2, EQ-5D, Colorado Symptoms Index, and physical/mental health visual analogue scales. We examined the construct validity of the SF-12v2 through confirmatory factor analyses (CFA), and using ANOVA/correlation analyses to compare the SF-12v2 to the other instruments to ascertain discriminant/convergent validity. Results Our CFA showed that the measurement properties of the original SF-12v2 model had a mediocre fit with our empirical data (χ2 = 193.6, df = 43, p < .0001, CFI = 0.85, NFI = 0.83, RMSEA = 0.08). We demonstrate that changes based on theoretical rationale and previous studies can significantly improve the model, achieving an excellent fit in our final model (χ2 = 160.6, df = 48, p < .0001, CFI = 0.95, NFI = 0.95, RMSEA = 0.06). Our CFA results suggest that an alternative scoring method based on the new model may optimize health status measurement of a homeless population. Despite these issues, convergent and discriminant validity of the SF-12v2 (scored based on the original model) was supported through multiple comparisons with other instruments. Conclusion Our study demonstrates for the first time that the SF-12v2 is generally appropriate as a measure of physical and mental health status for a homeless population with mental illness.

Varela, Begoña; Sesto, Vanessa; García-Rodeja, Isabel

2018-03-01

There are several studies dealing with students' conceptions on climate change, but most of them refer to understanding before instruction. In contrast, this study investigates students' conceptions and describes the levels of sophistication of their mental models on climate change and the greenhouse effect. The participants were 40 secondary students (grade 7) in Spain. As a method of data collection, a questionnaire was designed with open-ended questions focusing on the mechanism, causes, and actions that could be useful in reducing climate change. Students completed the same questionnaire before and after instruction. The students' conceptions and mental models were identified by an inductive and iterative analysis of the participants' explanations. With regard to the students' conceptions, the results show that they usually link climate change to an increase in temperature, and they tend to mention, even after instruction, generic actions to mitigate climate change, such as not polluting. With regard to the students' mental models, the results show an evolution of models with little consistency and coherence, such as the models on level 1, towards higher levels of sophistication. The paper concludes with educational implications proposed for solving learning difficulties regarding the greenhouse effect and climate change.

Visuo-spatial skills are believed to be enhanced in autism spectrum disorders (ASDs). This meta-analysis tests the current state of evidence for Figure Disembedding, Block Design, Mental Rotation and Navon tasks in ASD and neurotypicals. Block Design (d = 0.32) and Figure Disembedding (d = 0.26) showed superior performance for ASD with large heterogeneity that is unaccounted for. No clear differences were found for Mental Rotation. ASD samples showed a stronger local processing preference for Navon tasks (d = 0.35); less clear evidence for performance differences of a similar magnitude emerged. We discuss the meta-analysis results together with other findings relating to visuo-spatial processing and three cognitive theories of ASD: Weak Central Coherence, Enhanced Perceptual Functioning and Extreme Male Brain theory.

Pragmatics in discourse performance: insights from aphasiology.

PubMed

Ulatowska, Hanna K; Olness, Gloria Streit

2007-05-01

This article examines the preservation of pragmatic abilities of individuals with aphasia, as manifested in the discourse they produce. The construct of coherence is used as a framework for understanding this pragmatic preservation. Discourse coherence is largely derived from the structure, selection, and highlighting of information expressed in a discourse. Personal narratives, as one type of discourse, represent an extended turn-in-conversation on a topic of personal relevance to the speaker, common in everyday life. As such, they provide a valuable source of information about a speaker's pragmatic ability. Examples of personal narratives told by individuals with aphasia are used to illustrate and discuss the means by which discourse coherence is achieved. These include a tightly structured temporal-causal event line, development of theme, and evaluation of information. Possible approaches to clinical assessment are considered, including use of global rating systems.

Quantum coherent control of the photoelectron angular distribution in bichromatic-field ionization of atomic neon

2018-01-01

We investigate the coherent control of the photoelectron angular distribution in bichromatic atomic ionization. Neon is selected as target since it is one of the most popular systems in current gas-phase experiments with free-electron lasers (FELSs). In particular, we tackle practical questions, such as the role of the fine-structure splitting, the pulse length, and the intensity. Time-dependent and stationary perturbation theory are employed, and we also solve the time-dependent Schrödinger equation in a single-active electron model. We consider neon ionized by a FEL pulse whose fundamental frequency is in resonance with either 2 p -3 s or 2 p -4 s excitation. The contribution of the nonresonant two-photon process and its potential constructive or destructive role for quantum coherent control is investigated.

A Second-Order Phase Transition as a Limit of the First-Order Phase Transitions —Coherent Anomalies and Critical Phenomena in the Potts Models—

NASA Astrophysics Data System (ADS)

Katori, Makoto

1988-12-01

A new scheme of the coherent-anomaly method (CAM) is proposed to study critical phenomena in the models for which a mean-field description gives spurious first-order phase transition. A canonical series of mean-field-type approximations are constructed so that the spurious discontinuity should vanish asymptotically as the approximate critical temperature approachs the true value. The true value of the critical exponents β and γ are related to the coherent-anomaly exponents defined among the classical approximations. The formulation is demonstrated in the two-dimensional q-state Potts models for q{=}3 and 4. The result shows that the present method enables us to estimate the critical exponents with high accuracy by using the date of the cluster-mean-field approximations.

We demonstrate a simple, compact and cost-efficient diode laser pumped frequency doubling system at 795 nm in the low power regime. In two configurations, a bow-tie four-mirror ring enhancement cavity with a PPKTP crystal inside and a semi-monolithic PPKTP enhancement cavity, we obtain 397.5nm ultra-violet coherent radiation of 35mW and 47mW respectively with a mode-matched fundamental power of about 110mW, corresponding to a conversion efficiency of 32% and 41%. The low loss semi-monolithic cavity leads to the better results. The constructed ultra-violet coherent radiation has good power stability and beam quality, and the system has huge potential in quantum optics and cold atom physics.

In quantum communications, vortex photons can encode higher-dimensional quantum states and build high-dimensional communication networks (HDCNs). The interfaces that connect different wavelengths are significant in HDCNs. We construct a coherent orbital angular momentum (OAM) frequency bridge via difference frequency conversion in a nonlinear bulk crystal for HDCNs. Using a single resonant cavity, maximum quantum conversion efficiencies from visible to infrared are 36%, 15%, and 7.8% for topological charges of 0,1, and 2, respectively. The average fidelity obtained using quantum state tomography for the down-converted infrared OAM-state of topological charge 1 is 96.51%. We also prove that the OAM is conserved in this process by measuring visible and infrared interference patterns. This coherent OAM frequency-down conversion bridge represents a basis for an interface between two high-dimensional quantum systems operating with different spectra.

Effects and side-effects of integrating care: the case of mental health care in the Netherlands

Purpose Description and analysis of the effects and side-effects of integrated mental health care in the Netherlands. Context of case Due to a number of large-scale mergers, Dutch mental health care has become an illustration of integration and coherence of care services. This process of integration, however, has not only brought a better organisation of care but apparently has also resulted in a number of serious side-effects. This has raised the question whether integration is still the best way of reorganising mental health care. Data sources Literature, data books, patients and professionals, the advice of the Dutch Commission for Mental Health Care, and policy papers. Case description Despite its organisational and patient-centred integration, the problems in the Dutch mental health care system have not diminished: long waiting lists, insufficient fine tuning of care, public order problems with chronic psychiatric patients, etc. These problems are related to a sharp rise in the number of mental health care registrations in contrast with a decrease of registered patients in first-level services. This indicates that care for people with mental health problems has become solely a task for the mental health care services (monopolisation). At the same time, integrated institutions have developed in the direction of specialised medical care (homogenisation). Monopolisation and homogenisation together have put the integrated institutions into an impossible divided position. Conclusions and discussion Integration of care within the institutions in the Netherlands has resulted in withdrawal of other care providers. These side-effects lead to a new discussion on the real nature and benefits of an integrated mental health care system. Integration requires also a broadly shared vision on good care for the various target groups. This would require a radicalisation of the distinction between care providers as well as a recognition of the different goals of mental health care. PMID:17786180

2016-08-01

The objective of this study was to assess whether the constructs of self-determination theory-autonomy, competence, and relatedness-are associated with adherence to outpatient follow-up appointments after psychiatric hospitalization. 242 individuals discharged from inpatient psychiatric treatment within the Veterans Health Administration completed surveys assessing self-determination theory constructs as well as measures of depression and barriers to treatment. Medical records were used to count the number of mental health visits and no-shows in the 14 weeks following discharge. Logistic regression models assessed the association between survey items assessing theory constructs and attendance at mental healthcare visits. In multivariate models, none of the self-determination theory factors predicted outpatient follow-up attendance. The constructs of self-determination theory as measured by a single self-report survey may not reliably predict adherence to post-hospital care. Need factors such as depression may be more strongly predictive of treatment adherence.

Research suggests stereotype endorsement or self-stigma serves as a barrier to functioning and well-being among persons with schizophrenia. Little is known about how stable self-stigma is and whether it is linked over time with related constructs such as discrimination experiences and psychological distress. Stereotype endorsement and discrimination experiences were assessed using the Internalized Stigma of Mental Illness Scale and psychological distress was assessed using the Emotional Discomfort component of the Positive and Negative Syndrome Scale, at three points in time across 1 year. Path analyses indicated that the constructs of stereotype endorsement and discrimination experiences are stable over periods of 5-7 months and may fluctuate over 12 months. Further, the constructs of stereotype endorsement and discrimination experiences were related to one another concurrently, but analyses failed to detect a relationship over time. Neither construct was related to psychological distress over time. Self-stigma is a stable construct in the short term, and is distinct from related constructs such as discrimination experiences and psychological distress.

"Heroes' invisible wounds of war:" constructions of posttraumatic stress disorder in the text of US federal legislation.

PubMed

Purtle, Jonathan

2016-01-01

Public policies contribute to the social construction of mental health problems. In this study, I use social constructivist theories of policy design and the methodology of ethnographic content analysis to qualitatively explore how posttraumatic stress disorder (PTSD) has been constructed as a problem in US federal legislation. I analyzed the text of 166 bills introduced between 1989 and 2009 and found that PTSD has been constructed as a problem unique to combat exposures and military populations. These constructions were produced through combat-related language and imagery (e.g., wounds, war, heroism), narratives describing PTSD as a military-specific phenomenon, and reinforced by the absence of PTSD in trauma-focused legislation targeting civilians. These constructions do not reflect the epidemiology of PTSD-the vast majority of people who develop the disorder have not experienced combat and many non-combat traumas (e.g., sexual assault) carry higher PTSD risk-and might constrain public and political discourse about the disorder and reify sociocultural barriers to the access of mental health services.

In mental health care practice and research it is increasingly recognized that clients' subjective perceptions of everyday occupations, such as satisfaction, are important in recovery from mental illness. Instruments thus need to be developed to assess satisfaction with everyday occupations. The aim of the present study was to assess psychometric properties of the 13-item Satisfaction with Daily Occupation (SDO-13) when used with people with mental health problems, including its internal consistency, factor structure, construct validity and whether the scale produced ceiling or floor effects. An additional question concerned if the factor structure varied whether the participants were, or were not, presently engaged in the activity they rated. The interview-based SDO-13 includes items pertaining to work/studies, leisure, home maintenance, and self-care occupations. Whether the person currently performs an occupation or not, he/she is asked to indicate his/her satisfaction with that occupation. The SDO-13 was completed with 184 persons with mental illness. Residual variables were created to remove the variation linked with currently performing the targeted occupation or not and to assess the factor structure of the SDO-13. The indicators of general satisfaction with daily occupations, self-esteem and global functioning were used to assess construct validity. The statistical methods included tests of homogeneity, confirmatory factor analysis and Pearson correlations. The internal consistency was satisfactory at 0.79. A three-factor solution indicated that the construct behind the SDO-13 was composed of three facets; Taking care of oneself and the home, Work and studies, and Leisure and relaxation. The same factor structure was valid for both original scores and the residuals. An expected pattern of correlations with the indicators was mainly found, suggesting basic construct validity. No ceiling or floor effects were found. Taken together, the findings suggest the SDO-13 is a reliable and robust instrument that may be used to get an overview of the satisfaction people living with mental illness derive from their daily occupations.

Pathways to Firesetting for Mentally Disordered Offenders: A Preliminary Examination.

Tyler, Nichola; Gannon, Theresa A

The current study aimed to investigate the specific pathways in the offence process for mentally disordered firesetters. In a previous study, an offence chain model was constructed (i.e., the Firesetting Offence Chain for Mentally Disordered Offenders, FOC-MD) using offence descriptions obtained from 23 mentally disordered firesetters, detailing the sequence of contextual, behavioural, affective, and cognitive factors that precipitate an incidence of firesetting for this population. The current study examines the prevalence of the specific pathways to firesetting for the original 23 mentally disordered firesetters and a further sample of 13 mentally disordered firesetters. Three distinct pathways to firesetting are identified within the FOC-MD: fire interest-childhood mental health, no fire interest-adult mental health, fire interest-adult mental health. In this article, we describe these three pathways in detail using illustrative case studies. The practice implications of these identified pathways are also discussed.

Hutchinson, Susan L; Fenton, Lara

2018-05-01

There is merit in understanding how recreation-oriented programs for adults living with mental illness address barriers to participation and how programming is structured to create safe and inclusive environments, resulting in programming that amplifies the benefits of recreation for mental well-being. Following an environmental scan of programs targeting adults living with mental illness in Canada, ten coordinators in community mental health settings were interviewed. Four themes were constructed to reflect characteristics deemed to be 'promising practices' related to recreation-oriented programming: (a) barriers and solutions to individual participation, (b) characteristics of welcoming and supportive environments, (c) leadership characteristics, and (d) program characteristics.

Although geometric phases in quantum evolution are historically overlooked, their active control now stimulates strategies for constructing robust quantum technologies. Here, we demonstrate arbitrary single-qubit holonomic gates from a single cycle of nonadiabatic evolution, eliminating the need to concatenate two separate cycles. Our method varies the amplitude, phase, and detuning of a two-tone optical field to control the non-Abelian geometric phase acquired by a nitrogen-vacancy center in diamond over a coherent excitation cycle. We demonstrate the enhanced robustness of detuned gates to excited-state decoherence and provide insights for optimizing fast holonomic control in dissipative quantum systems.

An experimental approach in generating Petal-like transverse modes, which are similar to what is seen in porro-prism resonators, has been successfully demonstrated. We hypothesize that the petal-like structures are generated from a coherent superposition of Laguerre-Gaussian modes of zero radial order and opposite azimuthal order. To verify this hypothesis, visually based comparisons such as petal peak to peak diameter and the angle between adjacent petals are drawn between experimental data and simulated data. The beam quality factor of the Petal-like transverse modes and an inner product interaction is also experimentally compared to numerical results.

Coherent population trapping with polarization modulation

Yun, Peter, E-mail: enxue.yun@obspm.fr; Guérandel, Stéphane; Clercq, Emeric de

Coherent population trapping (CPT) is extensively studied for future vapor cell clocks of high frequency stability. In the constructive polarization modulation CPT scheme, a bichromatic laser field with polarization and phase synchronously modulated is applied on an atomic medium. A high contrast CPT signal is observed in this so-called double-modulation configuration, due to the fact that the atomic population does not leak to the extreme Zeeman states, and that the two CPT dark states, which are produced successively by the alternate polarizations, add constructively. Here, we experimentally investigate CPT signal dynamics first in the usual configuration, a single circular polarization.more » The double-modulation scheme is then addressed in both cases: one pulse Rabi interaction and two pulses Ramsey interaction. The impact and the optimization of the experimental parameters involved in the time sequence are reviewed. We show that a simple seven-level model explains the experimental observations. The double-modulation scheme yields a high contrast similar to the one of other high contrast configurations like push-pull optical pumping or crossed linear polarization scheme, with a setup allowing a higher compactness. The constructive polarization modulation is attractive for atomic clock, atomic magnetometer, and high precision spectroscopy applications.« less

Uncivilizing "Mental Illness": Contextualizing Diverse Mental States and Posthuman Emotional Ecologies within The Icarus Project.

PubMed

Fletcher, Erica Hua

2018-03-01

This article argues humans should not be defined strictly at their physical boundaries with clear distinctions between anatomical bodies, mental states, and the rest of the world. Rather, diverse mental states, which are often diagnosed as "mental illness," take shape within greater environmental forces and flows, including those that are constructed online. Drawing from a multi-sited ethnography of The Icarus Project, a radical mental health community, the author situates online narratives written by two of its members within posthuman emotional ecologies in which the exchange of ideas online affects mental states in a profound way. These narratives can be seen as a new type of psychiatric resistance based in new technologies, one that "uncivilizes" mental illness by searching for alternative frameworks and metaphors to understand lived experiences with mental distress. This ethnographic perspective differs significantly from traditional bio-psychiatric models and interventions and can offer both patients and mental healthcare providers with an alternative language to frame mental health.

Gilles Deleuze: psychiatry, subjectivity, and the passive synthesis of time.

PubMed

Roberts, Marc

2006-10-01

Abstract Although 'modern' mental health care comprises a variety of theoretical approaches and practices, the supposed identification of 'mental illness' can be understood as being made on the basis of a specific conception of subjectivity that is characteristic of 'modernity'. This is to say that any perceived 'deviation' from this characteristically 'modern self' is seen as a possible 'sign' of 'mental illness', given a 'negative determination', and conceptualized in terms of a 'deficiency' or a 'lack'; accordingly, the 'ideal''therapeutic' aim of 'modern' mental health care can be understood as the 'rectification' of that 'deficiency' through a 're-instatement' of the 'modern self'. Although contemporary mental health care is increasingly becoming influenced by the so-called 'death' of the 'modern self', this paper will suggest that it is the work of the 20th century French philosopher, Gilles Deleuze, that is able to provide mental health care with a coherent determination of a 'post-modern self'. However, a Deleuzian account of subjectivity stands in stark contrast to 'modernity's' conception of subjectivity and, as such, this paper will attempt to show how this 'post-modern' subjectivity challenges many of the assumptions of 'modern' mental health care. Moreover, acknowledging the complexity and the perceived difficulty of Deleuze's work, this paper will provide an account of subjectivity that can be understood as 'Deleuzian' in its orientation, rather than 'Deleuze's theory of subjectivity', and therefore, this paper also seeks to stimulate further research and discussion of Deleuze's work on subjectivity, and how that work may be able to inform, and possibly even reform, the theoretical foundations and associated diagnostic and therapeutic practices of psychiatry, psychotherapy, and mental health nursing.

Memories of Holocaust-related traumatic experiences, sense of coherence, and survivors' subjective well-being in late life: some puzzling findings.

PubMed

Zeidner, Moshe; Aharoni-David, Eynat

2015-01-01

This study explores the nexus of relationships between memories of Holocaust-related early traumatic events, survivors' sense of coherence (SOC), and subjective well-being (SWB) in late life. The basic design of this study, based 106 survivors (54% female), was cross-sectional. Participants underwent an extensive in-depth clinical interview relating to their Holocaust experiences and responded to measures of SOC and SWB. These data provided no evidence for the moderating or "buffering" effect of SOC but showed support for indirect effects of SOC in the relationship between memory traces of specific traumatic experiences and adaptive outcomes. The results of the present study provide support for Antonovsky's salutogenic perspective. It is highly plausible that survivors who underwent severe experiences during the Holocaust period were forced to call upon all their inner strengths and coping resources,and that their success in doing so and also surviving this horrendous period, might have contributed to the development of a stronger sense of meaning and coherence, which, in turn lead to a better sense of mental health as they approach the final season of their lives.

Health-related quality of life and sense of coherence among Polish immigrants in Germany and indigenous Poles.

PubMed

Morawa, Eva; Erim, Yesim

Immigrants are faced with several impediments in the host country that may affect their quality of life (QoL), but little is known about the impact of these stressors as well as about the protective role of sense of coherence (SoC) in the context of Polish immigration to Germany. Health Related QoL (Short Form Health Survey SF-36) and SoC (Sense of Coherence Scale SOC-29) were assessed in a total sample consisting of 511 participants aged between 18 and 84 years (260 Polish immigrants in Germany and 251 indigenous Poles). Polish immigrants reported a significantly lower mental and physical health-related QoL than the German norm population, but they were comparable to native Poles. This result remained the same when the model was adjusted for age but physical health status was better for immigrants compared with indigenous Poles. Both groups scored significantly lower for SoC than Germans, but did not differ from each other. The main differences concerning the examined variables were with respect to the German norm population and are putatively shaped by culture. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Self-Processing and the Default Mode Network: Interactions with the Mirror Neuron System

PubMed Central

Molnar-Szakacs, Istvan; Uddin, Lucina Q.

2013-01-01

Recent evidence for the fractionation of the default mode network (DMN) into functionally distinguishable subdivisions with unique patterns of connectivity calls for a reconceptualization of the relationship between this network and self-referential processing. Advances in resting-state functional connectivity analyses are beginning to reveal increasingly complex patterns of organization within the key nodes of the DMN – medial prefrontal cortex and posterior cingulate cortex – as well as between these nodes and other brain systems. Here we review recent examinations of the relationships between the DMN and various aspects of self-relevant and social-cognitive processing in light of emerging evidence for heterogeneity within this network. Drawing from a rapidly evolving social-cognitive neuroscience literature, we propose that embodied simulation and mentalizing are processes which allow us to gain insight into another’s physical and mental state by providing privileged access to our own physical and mental states. Embodiment implies that the same neural systems are engaged for self- and other-understanding through a simulation mechanism, while mentalizing refers to the use of high-level conceptual information to make inferences about the mental states of self and others. These mechanisms work together to provide a coherent representation of the self and by extension, of others. Nodes of the DMN selectively interact with brain systems for embodiment and mentalizing, including the mirror neuron system, to produce appropriate mappings in the service of social-cognitive demands.

How do thoughts, emotions, and decisions align? A new way to examine theory of mind during middle childhood and beyond.

PubMed

Lagattuta, Kristin Hansen; Elrod, Noel M; Kramer, Hannah J

2016-09-01

The current study examined 4- to 10-year-olds' and adults' (N=280) tendency to connect people's thoughts, emotions, and decisions into valence-matched mental state triads (thought valence=emotion valence=decision valence; e.g., anticipate something bad+feel worried+avoid) and valence-matched mental state dyads (thought-emotion, thought-decision, and emotion-decision). Participants heard vignettes about focal characters who re-encountered individuals who had previously harmed them twice, helped them twice, or both harmed and helped them. Baseline trials involved no past experience. Children and adults predicted the focal characters' thoughts (anticipate something good or bad), emotions (feel happy or worried), and decisions (go near or stay away). Results showed significant increases between 4 and 10years of age in the formation of valence-matched mental state triads and dyads, with thoughts and emotions most often aligned by valence. We also documented age-related improvement in awareness that uncertain situations elicit less valence-consistent mental states than more certain situations, with females expecting weaker coherence among characters' thoughts, emotions, and decisions than males. Controlling for age and sex, individuals with stronger executive function (working memory and inhibitory control) predicted more valence-aligned mental states. These findings add to the emerging literature on development and individual differences in children's reasoning about mental states and emotions during middle childhood and beyond.

Assessment of the results of treatment for mental disorders becomes more complete when the patient's perspective is incorporated. Here, we aimed to evaluate the psychometric properties and application of the Perceived Change Scale - Patient version (PCS-P) in a sample of inpatients with mental disorders. One hundred and ninety-one psychiatric inpatients answered the PCS-P and the Patients' Satisfaction with Mental Health Services Scale (SATIS) and were evaluated in terms of clinical and sociodemographic data. An exploratory factor analysis (EFA) was performed and internal consistency was calculated. The clinical impressions of the patient, family, and physician were correlated with the patient's perception of change. The EFA indicated a psychometrically suitable four-factor solution. The PCS-P exhibited a coherent relationship with SATIS and had a Cronbach's alpha value of 0.856. No correlations were found between the physician's clinical global impression of improvement and the patient's perception of change, although a moderate positive correlation was found between the patients' clinical global impression of improvement and the change perceived by the patient. The PCS-P exhibited adequate psychometric proprieties in a sample of inpatients with mental disorders. The patient's perception of change is an important dimension for evaluation of outcomes in the treatment of mental disorders and differs from the physician's clinical impression of improvement. Evaluation of positive and negative perceptions of the various dimensions of the patient's life enables more precise consideration of the patient's priorities and interests.

A Stress-Coping Model of Mental Illness Stigma: I. Predictors of Cognitive Stress Appraisal

PubMed Central

Rüsch, Nicolas; Corrigan, Patrick W.; Wassel, Abigail; Michaels, Patrick; Olschewski, Manfred; Wilkniss, Sandra; Batia, Karen

2009-01-01

Stigma can be a major stressor for individuals with schizophrenia and other mental illnesses. It is unclear, however, why some stigmatized individuals appraise stigma as more stressful, while others feel they can cope with the potential harm posed by public prejudice. We tested the hypothesis that the level of perceived public stigma and personal factors such as rejection sensitivity, perceived legitimacy of discrimination and ingroup perceptions (group value; group identification; entitativity, or the perception of the ingroup of people with mental illness as a coherent unit) predict the cognitive appraisal of stigma as a stressor. Stigma stress appraisal refers to perceived stigma-related harm exceeding perceived coping resources. Stress appraisal, stress predictors and social cue recognition were assessed in 85 people with schizophrenia, schizoaffective or affective disorders. Stress appraisal did not differ between diagnostic subgroups, but was positively correlated with rejection sensitivity. Higher levels of perceived societal stigma and holding the group of people with mental illness in low regard (low group value) independently predicted high stigma stress appraisal. These predictors remained significant after controlling for social cognitive deficits, depressive symptoms and diagnosis. Our findings support the model that public and personal factors predict stigma stress appraisal among people with mental illness, independent of diagnosis and clinical symptoms. Interventions that aim to reduce the impact of stigma on people with mental illness could focus on variables such as rejection sensitivity, a personal vulnerability factor, low group value and the cognitive appraisal of stigma as a stressor.

On the structure of personality disorder traits: conjoint analyses of the CAT-PD, PID-5, and NEO-PI-3 trait models.

PubMed

Wright, Aidan G C; Simms, Leonard J

2014-01-01

The current study examines the relations among contemporary models of pathological and normal range personality traits. Specifically, we report on (a) conjoint exploratory factor analyses of the Computerized Adaptive Test of Personality Disorder static form (CAT-PD-SF) with the Personality Inventory for the Diagnostic and Statistical Manual of Mental Disorders, fifth edition and NEO Personality Inventory-3 First Half, and (b) unfolding hierarchical analyses of the three measures in a large general psychiatric outpatient sample (n = 628; 64% Female). A five-factor solution provided conceptually coherent alignment among the CAT-PD-SF, PID-5, and NEO-PI-3FH scales. Hierarchical solutions suggested that higher-order factors bear strong resemblance to dimensions that emerge from structural models of psychopathology (e.g., Internalizing and Externalizing spectra). These results demonstrate that the CAT-PD-SF adheres to the consensual structure of broad trait domains at the five-factor level. Additionally, patterns of scale loadings further inform questions of structure and bipolarity of facet and domain level constructs. Finally, hierarchical analyses strengthen the argument for using broad dimensions that span normative and pathological functioning to scaffold a quantitatively derived phenotypic structure of psychopathology to orient future research on explanatory, etiological, and maintenance mechanisms.

To compare the 12-month choroidal thickness (CT) change between Alzheimer disease (AD) patients and normal subjects. In this prospective, observational study, 39 patients with a diagnosis of mild to moderate AD and 39 age-matched control subjects were included. All the subjects underwent neuropsychological (Mini Mental State Examination, Alzheimer disease Assessment Scale-Cognitive Subscale, and the Clinical Dementia Rating Scale) and ophthalmological evaluation, including spectral domain optical coherence tomography, at baseline and after 12 months. CT was measured manually using the caliper tool of the optical coherence tomography device. After 12 months, AD patients had a greater reduction of CT than controls (P≤0.05, adjusted for baseline CT, age, sex, axial length, and smoking). CT in patients with AD showed a rate of thinning greater than what could be expected during the natural course of aging.

No studies have examined the impact of personality traits on mental health among caregivers of individuals with severe brain injury. Therefore, the purpose of the current study was to construct linear growth models to examine whether the personality traits of family members of individuals with severe brain injury could predict the trajectories of their own mental health-related quality of life (HRQoL), anxiety, and depression beginning in a neurointensive care unit through 1 year after injury. Danish family members of individuals with severe brain injury (n = 52) completed the Short Form-36 assessing mental HRQoL (vitality, social functioning, role limitations-emotional, mental health), anxiety, and depression across 5 time points during the 1st year after injury. The measure of personality was administered 3 months after the patients' discharge. All mental HRQoL, anxiety, and depression variables improved significantly over time. Caregivers who were less neurotic and less conscientious had higher vitality, social functioning, and mental health over time, whereas caregivers who were more agreeable had higher social functioning over time. Caregivers with lower neuroticism had lower anxiety and depression over time, as well as a more accelerated decrease in anxiety and depression. Caregivers' personality traits were strongly associated over time with mental HRQoL, anxiety, and depression, with neuroticism being especially important for trajectories of anxiety and depression. These results suggest that personality assessments for caregivers of individuals with severe brain injury could help identify those most at risk for poor mental health over the course of rehabilitation.

Cognitive and affective components of mental workload: Understanding the effects of each on human decision making behavior

NASA Technical Reports Server (NTRS)

Nygren, Thomas E.

1992-01-01

Human factors and ergonomics researchers have recognized for some time the increasing importance of understanding the role of the construct of mental workload in flight research. Current models of mental workload suggest that it is a multidimensional and complex construct, but one that has proved difficult to measure. Because of this difficulty, emphasis has usually been placed on using direct reports through subjective measures such as rating scales to assess levels of mental workload. The NASA Task Load Index (NASA/TLX, Hart and Staveland) has been shown to be a highly reliable and sensitive measure of perceived mental workload. But a problem with measures like TLX is that there is still considerable disagreement as to what it is about mental workload that these subjective measures are actually measuring. The empirical use of subjective workload measures has largely been to provide estimates of the cognitive components of the actual mental workload required for a task. However, my research suggests that these measures may, in fact have greater potential in accurately assessing the affective components of workload. That is, for example, TLX may be more likely to assess the positive and negative feelings associated with varying workload levels, which in turn may potentially influence the decision making behavior that directly bears on performance and safety issues. Pilots, for example, are often called upon to complete many complex tasks that are high in mental workload, stress, and frustration, and that have significant dynamic decision making components -- often ones that involve risk as well.

There is growing recognition in mental health for the perspective of individuals with lived experience of mental health problems and mental health service use. As peer workers, these individuals can use their specific experience to benefit and support peers and professional caregivers, and to participate at all levels of mental health-care systems. The aim of the present study was to develop a conceptual framework representing the driving forces of peer workers to fullfil their position in mental health-care systems. A qualitative interview approach was employed using principles of grounded theory. Over a period of 5 months in 2014-2015, semistructured interviews were conducted with 14 peer workers in residential and community mental health-care systems. The emerged conceptual framework reveals that peer workers strive towards constructing a positive identity. This process is powered by driving forces reflecting a desire for normalization and an urge for self-preservation. Peer workers realize a meaningful employment by using their lived experience perspective as an asset, liberating themselves out of restrictive role patterns, and by breaking down stigma and taboo. As a precondition to engage in these normalization processes, peer workers perceive they need to secure their self-preservation by balancing the emergence of adverse emotional fluctuations. The conceptual framework can inform the development of work contexts in which peer workers have an authentic and meaningful contribution, while being offered sufficient support and learning opportunities to manage their well-being. © 2017 Australian College of Mental Health Nurses Inc.

Social exclusion can be both a cause and a consequence of mental health problems. Socially inclusive practice by mental health professionals can mitigate against the stigmatizing and excluding effects of severe mental illness. To develop and test the validity of a measure of social inclusion for individuals with severe mental illness - the Social Inclusion Questionnaire User Experience (SInQUE). The domains of the SInQUE were chosen to reflect the domains of social inclusion identified in the Poverty and Social Exclusion Survey. Patients with severe mental illness were recruited from rehabilitation, general and forensic psychiatric services and were asked to complete the questionnaire in an individual interview with a researcher. Sixty six patients with schizophrenia and schizoaffective disorder completed the SInQUE, alongside measures of psychiatric symptoms, needs and quality of life, to assess its acceptability, and concurrent and construct (convergent and discriminant) validity. The SInQUE took 45 minutes to complete and was found to have good concurrent and discriminant validity. Convergent validity was established for two domains: social integration and productivity. Preliminary findings suggest that the SInQUE may be a useful tool for assessing and monitoring social inclusion in individuals with severe mental illness. It has construct and concurrent validity with measures of unmet need and quality of life in this group. Further testing of the reliability of the SInQUE on a larger population is indicated.

Despite the potential impact of shared decision making on users satisfaction with care and quality in health care decisions, there is a lack of knowledge and skills regarding how to work with shared decision making among health care providers. The aim of this study was to evaluate the psychometric properties of three instruments that measure varied dimensions of shared decision making, based on self-reports by clients, in a Swedish community mental health context. The study sample consisted of 121 clients with experience of community mental health care, and involved in a wide range of decisions regarding both social support and treatment. The questionnaires were examined for face and content validity, internal consistency, test-retest reliability and construct validity. The instruments displayed good face and content validity, satisfactory internal consistency and a moderate to good level of stability in test-retest reliability with fair to moderate construct correlations, in a sample of clients with serious mental illness and experience of community mental health services in Sweden. The questionnaires are considered to be relevant to the decision making process, user-friendly and appropriate in a Swedish community mental health care context. They functioned well in settings where non-medical decisions, regarding social and support services, are the primary focus. The use of instruments that measure various dimensions of the self-reported experience of clients, can be a key factor in developing knowledge of how best to implement shared decision making in mental health services.

A perspective on coherent structures and conceptual models for turbulent boundary layer physics

NASA Technical Reports Server (NTRS)

Robinson, Stephen K.

1990-01-01

Direct numerical simulations of turbulent boundary layers have been analyzed to develop a unified conceptual model for the kinematics of coherent motions in low Reynolds number canonical turbulent boundary layers. All classes of coherent motions are considered in the model, including low-speed streaks, ejections and sweeps, vortical structures, near-wall and outer-region shear layers, sublayer pockets, and large-scale outer-region eddies. The model reflects the conclusions from the study of the simulated boundary layer that vortical structures are directly associated with the production of turbulent shear stresses, entrainment, dissipation of turbulence kinetic energy, and the fluctuating pressure field. These results, when viewed from the perspective of the large body of published work on the subject of coherent motions, confirm that vortical structures may be considered the central dynamic element in the maintenance of turbulence in the canonical boundary layer. Vortical structures serve as a framework on which to construct a unified picture of boundary layer structure, providing a means to relate the many known structural elements in a consistent way.

Generating the local oscillator "locally" in continuous-variable quantum key distribution based on coherent detection

DOE PAGES

Qi, Bing; Lougovski, Pavel; Pooser, Raphael C.; ...

2015-10-21

Continuous-variable quantum key distribution (CV-QKD) protocols based on coherent detection have been studied extensively in both theory and experiment. In all the existing implementations of CV-QKD, both the quantum signal and the local oscillator (LO) are generated from the same laser and propagate through the insecure quantum channel. This arrangement may open security loopholes and limit the potential applications of CV-QKD. In our paper, we propose and demonstrate a pilot-aided feedforward data recovery scheme that enables reliable coherent detection using a “locally” generated LO. Using two independent commercial laser sources and a spool of 25-km optical fiber, we construct amore » coherent communication system. The variance of the phase noise introduced by the proposed scheme is measured to be 0.04 (rad 2), which is small enough to enable secure key distribution. This technology opens the door for other quantum communication protocols, such as the recently proposed measurement-device-independent CV-QKD, where independent light sources are employed by different users.« less

In this work, a transmission-type, low-kilovolt coherent electron diffractive imaging instrument was constructed. It comprised a single-atom field emitter, a triple-element electrostatic lens, a sample holder, and a retractable delay line detector to record the diffraction patterns at different positions behind the sample. It was designed to image materials thinner than 3 nm. The authors analyzed the asymmetric triple-element electrostatic lens for focusing the electron beams and achieved a focused beam spot of 87 nm on the sample plane at the electron energy of 2 kV. High-angle coherent diffraction patterns of a suspended graphene sample corresponding to (0.62 Å){sup −1} were recorded. This workmore » demonstrated the potential of coherent diffractive imaging of thin two-dimensional materials, biological molecules, and nano-objects at a voltage between 1 and 10 kV. The ultimate goal of this instrument is to achieve atomic resolution of these materials with high contrast and little radiation damage.« less

Mass and tracer transport within oceanic Lagrangian coherent vortices as diagnosed in a global mesoscale eddying climate model

NASA Astrophysics Data System (ADS)

Tarshish, Nathaniel; Abernathey, Ryan; Dufour, Carolina; Frenger, Ivy; Griffies, Stephen

2017-04-01

Transient ocean mesoscale fluctuations play a central role in the global climate system, transporting climate relevant tracers such as heat and carbon. In satellite observations and numerical simulations, mesoscale vortices feature prominently as collectively rotating regions that remain visibly coherent. Prior studies on transport from ocean vortices typically rely on Eulerian identification methods, in which vortices are identified by selecting closed contours of Eulerian fields (e.g. sea surface height, or the Okubo-Weiss parameter) that satisfy geometric criteria and anomaly thresholds. In contrast, recent studies employ Lagrangian analysis of virtual particle trajectories initialized within the selected Eulerian contours, revealing significant discrepancies between the advection of the contour's material interior and the evolution of the Eulerian field contour. This work investigates the global mass and tracer transport associated with materially coherent surface ocean vortices. Further, it addresses differences between Eulerian and Lagrangian analyses for the detection of vortices. To do so, we use GFDL's CM2.6 coupled climate model with 5-10km horizontal grid spacing. We identify coherent vortices in CM2.6 by implementing the Rotationally Coherent Lagrangian Vortex (RCLV) framework, which recently emerged from dynamical systems theory. This approach involves the numerical advection of millions of Lagrangian particles and guarantees material coherence by construction. We compute the statistics, spatial distribution, and lifetimes of coherent vortices in addition to calculating the associated mass and tracer transports. We offer compelling evidence that Eulerian vortex methods are poorly suited to answer questions of mass and tracer transport.

Resilience: A psychobiological construct for psychiatric disorders.

PubMed

Shrivastava, Amresh; Desousa, Avinash

2016-01-01

Understanding of psychopathology of mental disorder is evolving, particularly with availability of newer insight from the field of genetics, epigenetics, social, and environmental pathology. It is now becoming clear how biological factors are contributing to development of an illness in the face of a number of psychosocial factors. Resilience is a psychobiological factor which determines individual's response to adverse life events. Resilience is a human capacity to adapt swiftly and successfully to stressful/traumatic events and manage to revert to a positive state. It is fundamental for growth of positive psychology which deals with satisfaction, adaptability, contentment, and optimism in people's life. Of late, there has been a paradigm shift in the understanding of resilience in context of stress risk vulnerability dimension. It is a neurobiological construct with significant neurobehavioral and emotional features which plays important role in deconstructing mechanism of biopsychosocial model of mental disorders. Resilience is a protective factor against development of mental disorder and a risk factor for a number of clinical conditions, e.g. suicide. Available information from scientific studies points out that resilience is modifiable factor which opens up avenues for a number of newer psychosocial as well as biological therapies. Early identification of vulnerable candidates and effectiveness of resilience-based intervention may offer more clarity in possibility of prevention. Future research may be crucial for preventive psychiatry. In this study, we aim to examine whether resilience is a psychopathological construct for mental disorder.

Clinical reasoning is a highly complex system with multiple inter-dependent mental activities. Gaining a better understanding of those cognitive processes has two practical implications: for physicians, being able to analyse their own reasoning method may prove to be helpful in diagnostic dead end; for medical teachers, identifying problem-solving strategies used by medical students may foster an appropriate individual feed-back aiming at improving their clinical reasoning skills. On the basis of a detailed literature review, the main diagnostic strategies and their related pattern of mental processes are described and illustrated with a concrete example, going from the patient's complaint to the chosen solution. Inductive, abductive and deductive diagnostic approaches are detailed. Different strategies for collecting data (exhaustive or oriented) and for problem-building are described. The place of problem solving strategies such as pattern-recognition, scheme inductive process, using of clinical script, syndrome grouping and mental hypotheses test is considered. This work aims at breaking up mental activities in process within clinical reasoning reminding that expert reasoning is characterised by the ability to use and structure the whole of these activities in a coherent system, using combined strategies in order to guarantee a better accuracy of their diagnosis.

Jabłoński, Marcin J; Szot-Parda, Magdalena; Grzegorek, Tomasz; Prusak, Jacek; Jach, Robert; Posadzka, Ewa

2016-01-01

Analysis and comparison of two types of motivation (autotelic and non-autotelic) which are behind the choice of medical specialisation by doctors in relation to their sense of coherence. Questionnaire method was used in the study. The study included a group of 86 graduates of the Faculty of Medicine of the Jagiellonian University, who have completed postgraduate internships at the Department of Haematology and Oncology, Department of Gynaecology of the Jagiellonian University and the L. Rydygier hospital in Krakow in 2010-2012. Statistical analyses were performed using the IBM SPSS Statistics 21. The level of significance was alpha = 0.05. It has been shown that doctors are more frequently characterised by the autotelic type of motivation. It has also been proven that there is a relationship between the male sex of the surveyed doctors and their autotelic type of motivation. Moreover, it has been demonstrated that there is a correlation between the comprehensibility component of the sense of coherence and the male sex. It has been also demonstrated that there is a correlation between meaningfulness component of the sense of coherence and the choice of surgical specialisation. Autotelic motivation prevails when choosing a medical specialty and this tendency is more noticeable in men than in women. The meaningfulness component of SoC plays a regulatory role in making career decisions related to the greater physical and mental pressure put on doctors. The observed differences in the types of motivation and the size of the components of the sense of coherence in groups of surveyed doctors - men and women - encourage further observations of these relationships on a larger population.

Objective: To investigate understand the current status of the sense of coherence and occupational stress in modern service workers, and to analyze the association between occupational stress and the sense of coherence. Methods: From March to April, 2016, 834 modern service workers from 3 companies in Shanghai, China (in air transportation industry, marketing industry, and travel industry) were surveyed by non-ran-dom sampling. The self-completion questionnaires were filled out anonymously given the informed consent of the workers. The occupational stress questionnaire was used to evaluate occupational stress, and the Chinese version of the Sense of Coherence Scale (SOC-13) was used to assess the mental health. Results: The mean score for the sense of coherence of the respondents was 61.54±10.46, and 50.1% of them were self-rated as having occupational stress. There were significant differences in SOC score between groups with different ages, marital status, positions, lengths of service, family per capita monthly income, and weekly work hours ( P <0.05). The occupational stress score differed significantly across groups with different marital status, lengths of service, and weekly work hours ( P <0.05). The scores for working autonomy, social support, and occupational stress differed significantly between groups with different SOC levels ( P< 0.05). There were significant differences in SOC score and the distribution of low-SOC respondents between groups with different levels of working autonomy, social support, and occupational stress. High SOC is a protective factor for occupational stress ( OR =0.39, 95% CI 0.26~ 0.59). Conclusion: Modern service workers in Shanghai have high SOC and moderate occupational stress. Therefore, improving SOC may reduce occupational stress.

Motion coherence affects human perception and pursuit similarly.

Pursuit and perception both require accurate information about the motion of objects. Recovering the motion of objects by integrating the motion of their components is a difficult visual task. Successful integration produces coherent global object motion, while a failure to integrate leaves the incoherent local motions of the components unlinked. We compared the ability of perception and pursuit to perform motion integration by measuring direction judgments and the concomitant eye-movement responses to line-figure parallelograms moving behind stationary rectangular apertures. The apertures were constructed such that only the line segments corresponding to the parallelogram's sides were visible; thus, recovering global motion required the integration of the local segment motion. We investigated several potential motion-integration rules by using stimuli with different object, vector-average, and line-segment terminator-motion directions. We used an oculometric decision rule to directly compare direction discrimination for pursuit and perception. For visible apertures, the percept was a coherent object, and both the pursuit and perceptual performance were close to the object-motion prediction. For invisible apertures, the percept was incoherently moving segments, and both the pursuit and perceptual performance were close to the terminator-motion prediction. Furthermore, both psychometric and oculometric direction thresholds were much higher for invisible apertures than for visible apertures. We constructed a model in which both perception and pursuit are driven by a shared motion-processing stage, with perception having an additional input from an independent static-processing stage. Model simulations were consistent with our perceptual and oculomotor data. Based on these results, we propose the use of pursuit as an objective and continuous measure of perceptual coherence. Our results support the view that pursuit and perception share a common motion-integration stage, perhaps within areas MT or MST.

Account of an optical beam spreading caused by turbulence for the problem of partially coherent wavefield propagation through inhomogeneous absorbing media

NASA Astrophysics Data System (ADS)

Dudorov, Vadim V.; Kolosov, Valerii V.

2003-04-01

The propagation problem for partially coherent wave fields in inhomogeneous media is considered in this work. The influence of refraction, inhomogeneity of gain medium properties and refraction parameter fluctuations on target characteristics of radiation are taken into consideration. Such problems arise in the study of laser propagation on atmosphere paths, under investigation of directional radiation pattern forming for lasers which gain media is characterized by strong fluctuation of dielectric constant and for lasers which resonator have an atmosphere area. The ray-tracing technique allows us to make effective algorithms for modeling of a partially coherent wave field propagation through inhomogeneous random media is presented for case when the influecne of an optical wave refraction, the influence of the inhomogeiety of radiaitn amplification or absorption, and also the influence of fluctuations of a refraction parameter on target radiation parameters are basic. Novelty of the technique consists in the account of the additional refraction caused by inhomogeneity of gain, and also in the method of an account of turbulent distortions of a beam with any initial coherence allowing to execute construction of effective numerical algorithms. The technique based on the solution of the equation for coherence function of the second order.

Quantum bits (qubits) are at the heart of quantum information processing schemes. Currently, solid-state qubits, and in particular the superconducting ones, seem to satisfy the requirements for being the building blocks of viable quantum computers, since they exhibit relatively long coherence times, extremely low dissipation, and scalability. The possibility of achieving quantum coherence in macroscopic circuits comprising Josephson junctions, envisioned by Legett in the 1980’s, was demonstrated for the first time in a charge qubit; since then, the exploitation of macroscopic quantum effects in low-capacitance Josephson junction circuits allowed for the realization of several kinds of superconducting qubits. Furthermore, coupling between qubits has been successfully achieved that was followed by the construction of multiple-qubit logic gates and the implementation of several algorithms. Here it is demonstrated that induced qubit lattice coherence as well as two remarkable quantum coherent optical phenomena, i.e., self-induced transparency and Dicke-type superradiance, may occur during light-pulse propagation in quantum metamaterials comprising superconducting charge qubits. The generated qubit lattice pulse forms a compound ”quantum breather” that propagates in synchrony with the electromagnetic pulse. The experimental confirmation of such effects in superconducting quantum metamaterials may open a new pathway to potentially powerful quantum computing. PMID:27403780

Chiropractors claim to locate, analyze and diagnose a putative spinal lesion known as subluxation and apply the mode of spinal manipulation (adjustment) for the correction of this lesion. The purpose of this examination is to review the current evidence on the epidemiology of the subluxation construct and to evaluate the subluxation by applying epidemiologic criteria for it's significance as a causal factor. The databases of PubMed, Cinahl, and Mantis were searched for studies using the keywords subluxation, epidemiology, manipulation, dose-response, temporality, odds ratio, relative risk, biological plausibility, coherence, and analogy. The criteria for causation in epidemiology are strength (strength of association), consistency, specificity, temporality (temporal sequence), dose response, experimental evidence, biological plausibility, coherence, and analogy. Applied to the subluxation all of these criteria remain for the most part unfulfilled. There is a significant lack of evidence to fulfill the basic criteria of causation. This lack of crucial supportive epidemiologic evidence prohibits the accurate promulgation of the chiropractic subluxation.

Exploring Persona-Scenarios - Using Storytelling to Create Design Ideas

NASA Astrophysics Data System (ADS)

Madsen, Sabine; Nielsen, Lene

This paper explores the persona-scenario method by investigating how the method can support project participants in generating shared understandings and design ideas. As persona-scenarios are stories we draw on narrative theory to define what a persona-scenario is and which narrative elements it should consist of. Based on an empirical study a key finding is that despite our inherent human ability to construct, tell, and interpret stories it is not easy to write and present a good, coherent, and design-oriented story without methodical support. The paper therefore contributes with guidelines that delineate a) what a design-oriented persona-scenario should consist of (product) and b) how to write it (procedure) in order to generate and validate as many, new, and shared understandings and design ideas as possible (purpose). The purpose of the guidelines is to facilitate the construction of persona-scenarios as good, coherent stories, which make sense to the storytellers and to the audience - and which therefore generate many, new, and shared understandings and design ideas.

2018-04-01

In this paper investigation of the enhanced fiber-optic low coherence Fabry-Pérot interferometer with zinc oxide (ZnO) film deposited by atomic layer deposition (ALD) was presented. Model of the interferometer, which was constructed of single-mode optical fiber with applied ZnO ALD films, was built. The interferometer was also examined by means of experiment. Measurements were performed for both reflective and transmission modes, using wavelengths of 1300 nm and 1500 nm. The measurements with the air cavity showed the best performance in terms of a visibility of the interference signal can be achieved for small cavity lengths ( 50μm) in both configurations. Combined with the enhancement of reflectance of the interferometer mirrors due to the ALD film, proposed construction could be successfully applied in refractive index (RI) sensor that can operate with improved visibility of the signal even in 1.3-1.5 RI range as well as with small volume samples, as shown by the modeling.

Sense of coherence (SOC) and mindfulness (MI) are believed to promote the health and well-being of individuals and organisations. The aim of this longitudinal study was to contribute to the literature on the development of SOC through training and interventions and thereby explore the development of these constructs in a group of senior professionals in the German Catholic Church. A sample of eight participants voluntarily enrolled for a 12-day training programme spread over a period of nine months to develop intercultural and inter-religious competencies, SOC and MI. Quantitative scores of the pre- and post-test SOC and MI questionnaires were qualitatively analysed. Results indicate that the majority of participants scored lower in the post-test on SOC and slightly higher in MI. The discussion explores the pitfalls in the development of these constructs in the study's participants and highlights the implications for theory and practice. Practical training implications for developing SOC and MI are offered.

Due to the highly light scattering nature of paper, the imaging depth of optical methods such as optical coherence tomography (OCT) is limited. In this work, we study the effect of refractive index matching on improving the imaging depth of OCT in paper. To this end, four different refractive index matching liquids (ethanol, 1-pentanol, glycerol and benzyl alcohol) with a refraction index between 1.359 and 1.538 were used in experiments. Low coherent light transmission was studied in commercial copy paper sheets, and the results indicate that benzyl alcohol offers the best improvement in imaging depth, while also being sufficiently stable for the intended purpose. Constructed cross-sectional images demonstrate visually that the imaging depth of OCT is considerably improved by optical clearing. Both surfaces of paper sheets can be detected along with information about the sheet's inner structure.

Coherent-state constellations and polar codes for thermal Gaussian channels

NASA Astrophysics Data System (ADS)

Lacerda, Felipe; Renes, Joseph M.; Scholz, Volkher B.

2017-06-01

Optical communication channels are ultimately quantum mechanical in nature, and we must therefore look beyond classical information theory to determine their communication capacity as well as to find efficient encoding and decoding schemes of the highest rates. Thermal channels, which arise from linear coupling of the field to a thermal environment, are of particular practical relevance; their classical capacity has been recently established, but their quantum capacity remains unknown. While the capacity sets the ultimate limit on reliable communication rates, it does not promise that such rates are achievable by practical means. Here we construct efficiently encodable codes for thermal channels which achieve the classical capacity and the so-called Gaussian coherent information for transmission of classical and quantum information, respectively. Our codes are based on combining polar codes with a discretization of the channel input into a finite "constellation" of coherent states. Encoding of classical information can be done using linear optics.

High-speed spectral domain polarization- sensitive optical coherence tomography using a single camera and an optical switch at 1.3 microm.

We propose high-speed spectral domain polarization-sensitive optical coherence tomography (SD-PS-OCT) using a single camera and a 1x2 optical switch at the 1.3-microm region. The PS-low coherence interferometer used in the system is constructed using free-space optics. The reflected horizontal and vertical polarization light rays are delivered via an optical switch to a single spectrometer by turns. Therefore, our system costs less to build than those that use dual spectrometers, and the processes of timing and triggering are simpler from the viewpoints of both hardware and software. Our SD-PS-OCT has a sensitivity of 101.5 dB, an axial resolution of 8.2 microm, and an acquisition speed of 23,496 A-scans per second. We obtain the intensity, phase retardation, and fast axis orientation images of a rat tail tendon ex vivo.

To evaluate the internal reliability and validity of the Brazilian Portuguese version of the Family Questionnaire among families of schizophrenia outpatients. The main studies about the family environment of schizophrenia patients are related to the concept of Expressed Emotion. There is currently no instrument to evaluate this concept in Brazil that is easily applicable and comparable with studies from other countries. Methodological and cross-sectional research design. A convenience sample of 130 relatives of schizophrenia outpatients was selected. The translation and cultural adaptation of the instrument involved experts in mental health and experts in the German language and included back translation, semantic evaluation of items and pretesting of the instrument with 30 relatives of schizophrenia outpatients. The psychometric properties of the instrument were studied with another 100 relatives, which fulfilled the requirements for the Brazilian Portuguese version of the instrument. The psychometric properties of the instrument were assessed by construct validity (using an analysis of its key components, comparisons between distinct groups-convergent validity with the Antonovsky's Sense of Coherence Scale) and reliability (checking the internal consistency of its items and its test-retest reproducibility). The analysis of main components confirmed dimensionality patterns that were comparable between the original and adapted versions. In two domains of the instrument, critical comments and emotional over-involvement had moderate and significant correlations, respectively, with Antonovsky's Sense of Coherence Scale, appropriate values of Cronbach's alpha and strong and significant correlations, respectively, in test-retest reproducibility. We observed significant differences between distinct groups of parents in the category of emotional over-involvement. We conclude that the Portuguese-adapted version of the Family Questionnaire is valid and reliable for the study sample. This study provided evidence that the Family Questionnaire is a reliable and valid instrument for assessing expressed emotion. It is easy and practical to use and is acceptable for use in a Brazilian cultural population. © 2012 Blackwell Publishing Ltd.

Positive Disintegration as a Process of Symmetry Breaking.

PubMed

Laycraft, Krystyna

2017-04-01

This article presents an analysis of the positive disintegration as a process of symmetry breaking. Symmetry breaking plays a major role in self-organized patterns formation and correlates directly to increasing complexity and function specialization. According to Dabrowski, a creator of the Theory of Positive Disintegration, the change from lower to higher levels of human development requires a major restructuring of an individual's psychological makeup. Each level of human development is a relatively stable and coherent configuration of emotional-cognitive patterns called developmental dynamisms. Their main function is to restructure a mental structure by breaking the symmetry of a low level and bringing differentiation and then integration to higher levels. The positive disintegration is then the process of transitions from a lower level of high symmetry and low complexity to higher levels of low symmetry and high complexity of mental structure.

In the field of children's knowledge of the earth, much debate has concerned the question of whether children's naive knowledge-that is, their knowledge before they acquire the standard scientific theory-is coherent (i.e., theory-like) or fragmented. We conducted two studies with large samples (N=328 and N=381) using a new paper-and-pencil test, denoted the EARTH (EArth Representation Test for cHildren), to discriminate between these two alternatives. We performed latent class analyses on the responses to the EARTH to test mental models associated with these alternatives. The naive mental models, as formulated by Vosniadou and Brewer, were not supported by the results. The results indicated that children's knowledge of the earth becomes more consistent as children grow older. These findings support the view that children's naive knowledge is fragmented.

The organizational context of children's mental health services.

PubMed

Glisson, Charles

2002-12-01

This paper reviews what is known about the organizational context of children's mental health services and describes organizational constructs, conceptual models, research methods, and intervention strategies that can be used to link organizational context to service quality and outcomes. Using evidence from studies of business and industrial organizations as well as studies of children's service organizations, the paper presents a model of organizational effectiveness that depends on several contextual characteristics that include organizational culture, structure, climate, and work attitudes. These characteristics are believed to affect the adoption of efficacious treatments (EBPs [evidence-based practices]), adherence to treatment protocols, therapeutic alliance, and the availability, responsiveness, and continuity of services. Finally, 10 components of the ARC(Availability Responsiveness and Continuity) organizational intervention are described as examples of strategies that can be used to develop organizational contexts with the prescribed characteristics. Mental health researchers are encouraged to consider including these constructs, conceptual models, research methods, and intervention strategies in dissemination, effectiveness, and implementation studies that address the gap between research-based knowledge about mental health treatment and what is actually offered in the community.

Coherent Transport in a Linear Triple Quantum Dot Made from a Pure-Phase InAs Nanowire.

2017-07-12

A highly tunable linear triple quantum dot (TQD) device is realized in a single-crystalline pure-phase InAs nanowire using a local finger gate technique. The electrical measurements show that the charge stability diagram of the TQD can be represented by three kinds of current lines of different slopes and a simulation performed based on a capacitance matrix model confirms the experiment. We show that each current line observable in the charge stability diagram is associated with a case where a QD is on resonance with the Fermi level of the source and drain reservoirs. At a triple point where two current lines of different slopes move together but show anticrossing, two QDs are on resonance with the Fermi level of the reservoirs. We demonstrate that an energetically degenerated quadruple point at which all three QDs are on resonance with the Fermi level of the reservoirs can be built by moving two separated triple points together via sophistically tuning of energy levels in the three QDs. We also demonstrate the achievement of direct coherent electron transfer between the two remote QDs in the TQD, realizing a long-distance coherent quantum bus operation. Such a long-distance coherent coupling could be used to investigate coherent spin teleportation and superexchange effects and to construct a spin qubit with an improved long coherent time and with spin state detection solely by sensing the charge states.

Techniques to measure complex-plane fields

In this work we construct coherent superpositions of Gaussian and vortex modes which can be described to occupy the complex-plane. We demonstrate how these fields can be experimentally constructed in a digital, controllable manner with a spatial light modulator. Once these fields have been generated we illustrate, with three separate techniques, how the constituent components of these fields can be extracted, namely by measuring the intensity of the field at two adjacent points; performing a modal decomposition and a new digital Stokes measurement.

We study the control of quantum interference in a four-level atom driven by three coherent fields forming a closed loop. The spontaneous emission spectrum shows two sets of peaks which are dramatically influenced by the fields. Due to destructive quantum interference, a dark line can be observed in the emission spectrum, and the condition of the dark line is given. We found that the conversion between destructive and constructive quantum interference can be achieved through controlling the Rabi frequency of the external fields.

The article approaches the comprehension of professionals that act in the mental health area about the movement of construction of social participation in the health system of Fortaleza, Ceará State. The methodology adopted is based upon qualitative approach. The study was developed with semi-structured interviews with 17 mental health professionals of the city above mentioned. The empirical data was analyzed through the technique of thematic content analysis, where it was identified three cores of analysis: social participation as space of citizenship and policy formulation; oriented to attention of collective needs; and decision taking. The study reveals that social participation represents a possibility of amplifying X the relations between the Civil Society and the State, which makes possible the social intervention in proposals of the health policies. It is highlighted the right to health linked to the consolidation of democracy in the attention to the needs and collective edification.

Exploring the effect of organizational culture on consumer perceptions of agency support for mental health recovery.

Clossey, Laurene; Rheinheimer, David

2014-05-01

This research explores the impact of mental health agency culture on consumers' perceptions of agency support for their recovery. This study hypothesized that a constructive organizational culture must be present for consumers to perceive agency support for recovery. A sample of 12 mental health agencies in rural Pennsylvania participated in the research. Agency administrators completed an instrument called the recovery oriented service environment, which measured the number of recovery model program components offered by the agency. Consumers completed the recovery oriented services indicators, which taps into their perception of agency support for recovery. Direct service staff completed the organizational social context, which measured their agency's culture. Results showed that in this sample stronger consumer perceptions of agency support for recovery were correlated with higher ratings of agency constructive culture. The results suggest that agency culture is an important variable to target when implementing recovery model programming.

Spirituality has been cited in the literature as having a positive effect on mental health outcomes. This paper explores the relationship of spirituality to demographic, psychiatric illness history and psychological constructs for people with mental illness (N=1835) involved in consumer-centered services (CCS-Clubhouses and Consumer run drop-in centers). Descriptive statistics indicate that spirituality is important for at least two thirds of the members in the study. Members primarily indicated participation in public spiritual activities (i.e., church, bible study groups), followed by private activities (prayer, reading the bible, and meditation) (both of which were centered on belief in the transcendent). A logistic regression analysis was done to explore variables related to spirituality (i.e., demographics, psychiatric illness history, and psychological constructs). Results suggest that age, gender, having psychotic symptoms, having depressive symptoms, and having a higher global quality of life, hope and sense of community were all significant correlates of spirituality.

British nurses' attitudes to electroconvulsive therapy, 1945-2000.

PubMed

Adams, John

2015-10-01

The aim of the study was to collect and analyse historical material on nurses' attitudes to electroconvulsive therapy in Britain between 1945-2000. Electroconvulsive therapy became widely used in Britain from the late 1940s onwards and remains in current use, but became one of the main targets of the 'antipsychiatry' movement of the 1960s and 1970s. A cultural history design was used to recreate the perspectives of mental health nurses in the period under review. A range of primary sources including journal articles, textbooks and oral history sources were combined to create a coherent historical account. The controversy surrounding electroconvulsive therapy created a deep-seated ambivalence towards it among mental health nurses. While a sizeable minority were critical of its use and may have taken steps to avoid involvement with it, most acquiesced in providing the treatment. Recorded incidents of outright refusal to participate are few. Mental health nurses' views on electroconvulsive therapy are reflective of the profession's growing knowledge of the use of evidence in debating whether particular therapies should be used. © 2015 John Wiley & Sons Ltd.

The Importance of Visual Experience, Gender, and Emotion in the Assessment of an Assistive Tactile Mouse.

2015-01-01

Tactile maps are efficient tools to improve spatial understanding and mobility skills of visually impaired people. Their limited adaptability can be compensated with haptic devices which display graphical information, but their assessment is frequently limited to performance-based metrics only which can hide potential spatial abilities in O&M protocols. We assess a low-tech tactile mouse able to deliver three-dimensional content considering how performance, mental workload, behavior, and anxiety status vary with task difficulty and gender in congenitally blind, late blind, and sighted subjects. Results show that task difficulty coherently modulates the efficiency and difficulty to build mental maps, regardless of visual experience. Although exhibiting attitudes that were similar and gender-independent, the females had lower performance and higher cognitive load, especially when congenitally blind. All groups showed a significant decrease in anxiety after using the device. Tactile graphics with our device seems therefore to be applicable with different visual experiences, with no negative emotional consequences of mentally demanding spatial tasks. Going beyond performance-based assessment, our methodology can help with better targeting technological solutions in orientation and mobility protocols.

Local measurements of the diffusion constant in multiple scattering media: Application to human trabecular bone imaging

NASA Astrophysics Data System (ADS)

Aubry, Alexandre; Derode, Arnaud; Padilla, Frédéric

2008-03-01

We present local measurements of the diffusion constant for ultrasonic waves undergoing multiple scattering. The experimental setup uses a coherent array of programmable transducers. By achieving Gaussian beamforming at emission and reception, an array of virtual sources and receivers located in the near field is constructed. A matrix treatment is proposed to separate the incoherent intensity from the coherent backscattering peak. Local measurements of the diffusion constant D are then achieved. This technique is applied to a real case: a sample of human trabecular bone for which the ultrasonic characterization of multiple scattering is an issue.

2014-04-01

Measurement-device-independent quantum key distribution (MDI-QKD), leaving the detection procedure to the third partner and thus being immune to all detector side-channel attacks, is very promising for the construction of high-security quantum information networks. We propose a scheme to implement MDI-QKD, but with continuous variables instead of discrete ones, i.e., with the source of Gaussian-modulated coherent states, based on the principle of continuous-variable entanglement swapping. This protocol not only can be implemented with current telecom components but also has high key rates compared to its discrete counterpart; thus it will be highly compatible with quantum networks.

We demonstrate that multiple-site sensing along an optical fiber can be done with incoherent continuous-wave light. Here, using a broadband low-coherence noise source, a slow detector, and an optical modulator, we construct a single-arm frequency-shifted interferometer (SA-FSI) capable of simultaneously sensing multiple weak-reflection sites distributed either in parallel or in series along fiber links. By scanning the driving frequency of an electro-optic amplitude modulator in the range of 2.7–3.2 GHz at steps of 41.7 KHz, we demonstrate a spatial resolution of 0.3 m and a measurement range of over 1 km.

The diagnosis of nasopharyngeal carcinoma by optical coherence tomography (OCT)

NASA Astrophysics Data System (ADS)

Li, J. H.; Du, Y.

2016-06-01

We have attempted to explore the intrinsic differences in the optical properties of the nasopharyngeal carcinoma (NPC) and normal tissue by optical coherence tomography (OCT). OCT imaging of normal tissue provided three layers of epithelium, lamina propria, and the brighter interface of basement membrane; while carcinomas disrupted the layered construction embedded in signal-poor images. The morphologies were consistent with histological findings. Sensitivity and specificity were 90% and 100%, respectively. This pilot study demonstrates that NPC could be diagnosed by visualization, which implies that OCT might be potentially used to differentiate normal from NPC tissue in the early stage as an invasive biopsy.

A customized 1310-nm Jones-matrix optical coherence tomography (JM-OCT) for dermatological investigation was constructed and used for in vivo normal human skin tissue imaging. This system can simultaneously measure the threedimensional depth-resolved local birefringence, complex-correlation based OCT angiography (OCT-A), degree-ofpolarization- uniformity (DOPU) and scattering OCT intensity. By obtaining these optical properties of tissue, the morphology, vasculature, and collagen content of skin can be deduced and visualized. Structures in the deep layers of the epithelium were observed with depth-resolved local birefringence and polarization uniformity images. These results suggest high diagnostic and investigative potential of JM-OCT for dermatology.

Culturally prescribed beliefs about mental illness among the Akan of Ghana.

Opare-Henaku, Annabella; Utsey, Shawn O

2017-08-01

Mental illness is a culturally laden phenomenon, and different cultures have unique ways of constructing mental illness. In this study, conceptions of mental illness were explored among 30 participants of Akan descent in Ghana through individual and group interviews. Participants demonstrated a wide range of knowledge on mental illness indicating that poor self-care, deficits in social functioning, and disordered behaviors are the cardinal features of mental illness. The data revealed that Akan cultural beliefs influenced notions of etiology of mental illness and care of the mentally ill. While participants recognized the role of multiple factors such as genetics, substance abuse, daily hassles (for example, concerns about basic needs such as food, clothing, and shelter), and trauma in the cause of mental illness, the predominant belief was that mental illness is a retributive and/or a spiritual illness. This belief encourages pluralistic health-seeking behaviors: use of hospitals, prayer camps, herbalists, and traditional healers. The implications of these findings for public health education on mental illness, and clinical training and practice are discussed.

Abstract Introduction: Positive mental health is increasingly recognized as an important focus for public health policies and programs. In Canada, the Mental Health Continuum— Short Form (MHC-SF) was identified as a promising measure to include on population surveys to measure positive mental health. It proposes to measure a three-factor model of positive mental health including emotional, social and psychological well-being. The purpose of this study was to examine whether the MHC-SF is an adequate measure of positive mental health for Canadian adults. Methods: We conducted confirmatory factor analysis (CFA) using data from the 2012 Canadian Community Health Survey (CCHS)—Mental Health Component (CCHS-MH), and cross-validated the model using data from the CCHS 2011–2012 annual cycle. We examined criterion-related validity through correlations of MHC-SF subscale scores with positively and negatively associated concepts (e.g. life satisfaction and psychological distress, respectively). Results: We confirmed the validity of the three-factor model of emotional, social and psychological well-being through CFA on two independent samples, once four correlated errors between items on the social well-being scale were added. We observed significant correlations in the anticipated direction between emotional, psychological and social well-being scores and related concepts. Cronbach’s alpha for both emotional and psychological well-being subscales was 0.82; for social well-being it was 0.77. Conclusion: Our study suggests that the MHC-SF measures a three-factor model of positive mental health in the Canadian population. However, caution is warranted when using the social well-being scale, which did not function as well as the other factors, as evidenced by the need to add several correlated error terms to obtain adequate model fit, a higher level of missing data on these questions and weaker correlations with related constructs. Social well-being is important in a comprehensive measure of positive mental health, and further research is recommended. PMID:28402801

Yager, Joel; Feinstein, Robert E

2017-04-01

Offering a new framework for understanding and studying basic dimensions of normal and abnormal human functioning and mental disorders, the National Institute of Mental Health (NIMH) has initiated the Research Domain Criteria (RDoC) project in which a series of higher order domains, representing major systems of emotion, cognition, motivation, and social behavior, and their constituent operationally defined constructs serve as organizing templates for further research and inquiry, eg, to discover validated biomarkers and endophenotypes. Cutting across traditional DSM diagnoses, the domains are defined as Negative Valence Systems, Positive Valence Systems, Cognitive Systems, Systems for Social Processes, and Arousal/Regulatory Systems. To inform educators, trainees, and practitioners about RDoC, alert them to potential practical applications, and encourage their broad exploration in clinical settings, this article reviews the RDoC domains and their subsystem constructs with regard to potential current clinical considerations and applications. We describe ways in which the RDoC domains and constructs offer transdiagnostic frameworks for complementing traditional practice; suggest clinical questions to help elucidate salient information; and, translating RDoC domains and constructs headings into clinically friendly language, offer a template for the psychiatric review of systems that can serve in clinical notes. © Copyright 2017 Physicians Postgraduate Press, Inc.

Positive mental health, rather than just the absence of mental illness, is rarely investigated among the internally displaced persons (IDPs) affected by violent conflict in low-income countries. The purpose of this study was to investigate a model that could explain the interrelationship between factors contributing to positive mental health in displaced populations. In a longitudinal study we examine poverty, exposure to traumatic events and the change of material well-being after one year. We collected data in two consecutive years (2005 and 2006) from a community-based sample of IDPs in Ambon, Indonesia, through face-to-face structured interviews with consenting adults. Participants of this study were IDPs lived in Ambon during the violent conflict period. We interviewed 471 IDPs in the first year and reinterviewed 399 (85%) of the same subjects in the second year. The IDPs possessed good sense of coherence and subjective well-being. Our final model, which was generated by the use of structural equation modeling, fits the data well (χ(2) = 52.51, df = 45, p = .21, CFI = .99, RMSEA = .019). Exposure to violent conflict had a negative impact on IDPs' mental health initially and better economic conditions improved it (r = -.30 and .29 respectively). Mental health status one year previously was a strong predictor of future mental health, followed by individual economic growth in the past year (r = .43 and .29 respectively). On a group level the IDPs were resilient and adaptive to survive in adverse living conditions after devastating violent conflict, and the economic improvement contributed to it.

The Big Five personality dimensions and mental health: The mediating role of alexithymia.

PubMed

Atari, Mohammad; Yaghoubirad, Mahsa

2016-12-01

The role of personality constructs on mental health has attracted research attention in the last few decades. The Big Five personality traits have been introduced as parsimonious dimensions of non-pathological traits. The five-factor model of personality includes neuroticism, agreeableness, conscientiousness, extraversion, and openness to experience. The present study aimed to examine the relationship between the Big Five dimensions and mental health considering the mediating role of alexithymia as an important emotional-processing construct. A total of 257 participants were recruited from non-clinical settings in the general population. All participants completed the Ten-Item Personality Inventory (TIPI), 20-item Toronto Alexithymia Scale (TAS-20), and General Health Questionnaire-28 (GHQ-28). Structural equation modeling was utilized to examine the hypothesized mediated model. Findings indicated that the Big Five personality dimensions could significantly predict scores of alexithymia. Moreover, alexithymia could predict mental health scores as measured by indices of depression, anxiety, social functioning, and somatic symptoms. The fit indices (GFI=0.94; CFI=0.91; TLI=0.90; RMSEA=0.071; CMIN/df=2.29) indicated that the model fits the data. Therefore, the relationship between the Big Five personality dimensions and mental health is mediated by alexithymia. Copyright © 2016 Elsevier B.V. All rights reserved.

Salutogenic factors for mental health promotion in work settings and organizations.

Graeser, Silke

2011-12-01

Accompanied by an increasing awareness of companies and organizations for mental health conditions in work settings and organizations, the salutogenic perspective provides a promising approach to identify supportive factors and resources of organizations to promote mental health. Based on the sense of coherence (SOC) - usually treated as an individual and personality trait concept - an organization-based SOC scale was developed to identify potential salutogenic factors of a university as an organization and work place. Based on results of two samples of employees (n = 362, n = 204), factors associated with the organization-based SOC were evaluated. Statistical analysis yielded significant correlations between mental health and the setting-based SOC as well as the three factors of the SOC yielded by factor analysis yielded three factors comprehensibility, manageability and meaningfulness. Significant statistic results of bivariate and multivariate analyses emphasize the significance of aspects such as participation and comprehensibility referring to the organization, social cohesion and social climate on the social level, and recognition on the individual level for an organization-based SOC. Potential approaches for the further development of interventions for work-place health promotion based on salutogenic factors and resources on the individual, social and organization level are elaborated and the transcultural dimensions of these factors discussed.

Multidimensional Architecture of Love: From Romantic Narratives to Psychometrics.

PubMed

Karandashev, Victor; Clapp, Stuart

2015-12-01

Romantic love has been explored by writers for centuries revealing multiple emotions and feelings related to this phenomenon. Scientific efforts to understand love began in the mid-twentieth century and greatly advanced the topic in the past few decades. Several instruments measuring love were developed. They are still, however, limited in their scope. The purpose of our study was to explore love's emotional complexity through discourse analysis of romantic narratives and apply the constructs identified in those narratives to the reality of love relationships. In the first study, the discourse analysis of quotes selected from a representative sample of romantic narratives lead to a comprehensive set of items measuring the variety of love constructs. Second and third studies, utilizing 498 participants of various ages, empirically explored the diversity of love constructs and their architecture. The study brought many constructs to the arena of love research. A hierarchical cluster analysis allowed depicting these dimensions in varying models. Mental representations of love structures varied depending on the participants' mental complexity and other factors.

The aim of this study was to validate a Task-Specific Self-Efficacy Scale for Chinese people with mental illness. The study included 79 men and 77 women with chronic mental illness. The Task-Specific Self-Efficacy Scale for People with Mental Illness (TSSES-PMI) and Change Assessment Questionnaire for People with Severe and Persistent Mental Illness were used as measures for the study. Factor analysis of the TSSES-PMI resulted in four subscales: Symptom Management Skills, Work-Related Skills, Help-Seeking Skills, and Self-Emotional-Regulation Skills. These community living skills were found to be related to the level of readiness for psychiatric rehabilitation among Chinese people with mental illness. In conclusion the results support the construct validity of the TSSES-PMI for the Chinese population and the TSSES-PMI can be a useful instrument for working with Chinese people with mental illnesses.

2013-01-01

Despite considerable recent interest, the biological basis and clinical diagnosis of behavioural variant frontotemporal dementia (bvFTD) pose unresolved problems. Mentalising (the cognitive capacity to interpret the behaviour of oneself and others in terms of mental states) is impaired as a prominent feature of bvFTD, consistent with involvement of brain regions including ventro-medial prefrontal cortex (PFC), orbitofrontal cortex and anterior temporal lobes. Here, we investigated mentalising ability in a cohort of patients with bvFTD using a novel modality: music. We constructed a novel neuropsychological battery requiring attribution of affective mental or non-mental associations to musical stimuli. Mentalising performance of patients with bvFTD (n = 20) was assessed in relation to matched healthy control subjects (n = 20); patients also had a comprehensive assessment of behaviour and general neuropsychological functions. Neuroanatomical correlates of performance on the experimental tasks were investigated using voxel-based morphometry of patients' brain magnetic resonance imaging (MRI) scans. Compared to healthy control subjects, patients showed impaired ability to attribute mental states but not non-mental characteristics to music, and this deficit correlated with performance on a standard test of social inference and with carer ratings of patients' empathic capacity, but not with other potentially relevant measures of general neuropsychological function. Mentalising performance in the bvFTD group was associated with grey matter changes in anterior temporal lobe and ventro-medial PFC. These findings suggest that music can represent surrogate mental states and the ability to construct such mental representations is impaired in bvFTD, with potential implications for our understanding of the biology of bvFTD and human social cognition more broadly.

Winslow, Brent D; Nguyen, Nam; Venta, Kimberly E

Sleep impairment significantly alters human brain structure and cognitive function, but available evidence suggests that adults in developed nations are sleeping less. A growing body of research has sought to use sleep to forecast cognitive performance by modeling the relationship between the two, but has generally focused on vigilance rather than other cognitive constructs affected by sleep, such as reaction time, executive function, and working memory. Previous modeling efforts have also utilized subjective, self-reported sleep durations and were restricted to laboratory environments. In the current effort, we addressed these limitations by employing wearable systems and mobile applications to gather objective sleep information, assess multi-construct cognitive performance, and model/predict changes to mental acuity. Thirty participants were recruited for participation in the study, which lasted 1 week. Using the Fitbit Charge HR and a mobile version of the automated neuropsychological assessment metric called CogGauge, we gathered a series of features and utilized the unified model of performance to predict mental acuity based on sleep records. Our results suggest that individuals poorly rate their sleep duration, supporting the need for objective sleep metrics to model circadian changes to mental acuity. Participant compliance in using the wearable throughout the week and responding to the CogGauge assessments was 80%. Specific biases were identified in temporal metrics across mobile devices and operating systems and were excluded from the mental acuity metric development. Individualized prediction of mental acuity consistently outperformed group modeling. This effort indicates the feasibility of creating an individualized, mobile assessment and prediction of mental acuity, compatible with the majority of current mobile devices.

Health-related quality of life and sense of coherence among the unemployed with autotelic, average, and non-autotelic personalities: a cross-sectional survey in Hiroshima, Japan.

Unemployment is known to have a negative effect on the quality of life (QOL) of individuals. However, the influence of an autotelic personality on QOL and SOC of unemployed individuals remains unclear. Our study compared health-related quality of life (HRQOL) and sense of coherence (SOC) among 3 groups: (i) an autotelic personality group (AP), which tends to "go with the flow," (ii) an average group (AV), and (iii) a non-autotelic personality group (NAP). In October 2010, we conducted a cross-sectional survey among 140 job trainees not receiving unemployment benefits in Hiroshima, Japan. We collected 134 completed questionnaires. Autotelic personality was investigated using the Flow Experience Checklist, health-related quality of life was assessed using the Short Form (SF-8) Health Survey, and SOC was measured using the University of Tokyo Health Sociology version of the SOC3 scale (SOC3-UTHS). The average age of participants was 36.14±11.54 year. Participants were classified into 3 groups based on daily activity values: 4+ for AP (n = 22), 1-3 for AV (n = 82), and 0 for NAP (n = 30). Significant differences were observed in mental component summary (MCS) score and SOC3-UTHS total scores in the ranking order of AP (highest), AV, and NAP. Our findings indicate a need to develop programs for facilitating AP among unemployed people to enhance mental QOL and SOC.

A critical evaluation of the validity of episodic future thinking: A clinical neuropsychology perspective.

PubMed

Ward, Amanda M

2016-11-01

Episodic future thinking is defined as the ability to mentally simulate a future event. Although episodic future thinking has been studied extensively in neuroscience, this construct has not been explored in depth from the perspective of clinical neuropsychology. The aim of this critical narrative review is to assess the validity and clinical implications of episodic future thinking. A systematic review of episodic future thinking literature was conducted. PubMed and PsycInfo were searched through July 2015 for review and empirical articles with the following search terms: "episodic future thinking," "future mental simulation," "imagining the future," "imagining new experiences," "future mental time travel," "future autobiographical experience," and "prospection." The review discusses evidence that episodic future thinking is important for adaptive functioning, which has implications for neurological populations. To determine the validity of episodic future thinking, the construct is evaluated with respect to related constructs, such as imagination, episodic memory, autobiographical memory, prospective memory, narrative construction, and working memory. Although it has been minimally investigated, there is evidence of convergent and discriminant validity for episodic future thinking. Research has not addressed the incremental validity of episodic future thinking. Practical considerations of episodic future thinking tasks and related constructs in a clinical neuropsychological setting are considered. The utility of episodic future thinking is currently unknown due to the lack of research investigating the validity of episodic future thinking. Future work is discussed, which could determine whether episodic future thinking is an important missing piece in standard clinical neuropsychological assessment.

[Motivation as a basis of mental activity].

PubMed

Sudakov, K V

2006-01-01

Motivation is considered as a key component of systemic organization of mental activity. Forming on the stage of afferent synthesis, motivation determines activity of the subsequent systemic architectonic stages of mental acts: decision-making, construction of an acceptor of resulting actions, efferent synthesis and the very purposeful action. It is shown that motivation acts as an energy basis of mental activity. The foresight instrument of required resulting actions--an acceptor of resulting actions that, strongly linked to dominating motivation, is a leading guiding component of mental actions. A role of motivation in the processes of perception, memory, movement organization, intellectual and creative activity and their relationship to emotions are considered. A conception of motivation as a basis of intellect is formulated.

Smartphone technology is being increasingly viewed as key to engaging young adults with schizophrenia in their own mental health care. In an attempt to use smartphones as an engagement tool, we conducted a participatory design process, where young adults with schizophrenia (n = 4), healthcare providers (n = 7), software designers (n = 3), graphic designer (n = 1), graphic recorder (n = 1), and team leader (n = 1) co-designed a smartphone application for use in early phase schizophrenia care. This paper reports the co-design process. Based on a variety of written data-sources, the paper describes if, and how, participatory design can help construct a physical and relational environment that enables young adults with schizophrenia to become active participants in the design of a more participatory mental health practice. Guided by Etienne Wenger's construct of Community of Practice, three major categories of characteristics and construction of a physical and relational environment supporting and inspiring participation and engagement were identified: (i) a pre-narrative about a community of practice, (ii) the room for design is a community of practice and (iii) the community of practice as a practice of special qualities. It is concluded that participatory design can support and inspire participation and engagement in the development of mental health care with young adults with schizophrenia, given that the environment in which participatory design unfolds is transparent, flexible, secure and informal. © 2016 Australian College of Mental Health Nurses Inc.

Resilience: A psychobiological construct for psychiatric disorders

PubMed Central

Shrivastava, Amresh; Desousa, Avinash

2016-01-01

Understanding of psychopathology of mental disorder is evolving, particularly with availability of newer insight from the field of genetics, epigenetics, social, and environmental pathology. It is now becoming clear how biological factors are contributing to development of an illness in the face of a number of psychosocial factors. Resilience is a psychobiological factor which determines individual's response to adverse life events. Resilience is a human capacity to adapt swiftly and successfully to stressful/traumatic events and manage to revert to a positive state. It is fundamental for growth of positive psychology which deals with satisfaction, adaptability, contentment, and optimism in people's life. Of late, there has been a paradigm shift in the understanding of resilience in context of stress risk vulnerability dimension. It is a neurobiological construct with significant neurobehavioral and emotional features which plays important role in deconstructing mechanism of biopsychosocial model of mental disorders. Resilience is a protective factor against development of mental disorder and a risk factor for a number of clinical conditions, e.g. suicide. Available information from scientific studies points out that resilience is modifiable factor which opens up avenues for a number of newer psychosocial as well as biological therapies. Early identification of vulnerable candidates and effectiveness of resilience-based intervention may offer more clarity in possibility of prevention. Future research may be crucial for preventive psychiatry. In this study, we aim to examine whether resilience is a psychopathological construct for mental disorder. PMID:26985103

Numerical modeling of mountain formation on Io

NASA Astrophysics Data System (ADS)

Turtle, E. P.; Jaeger, W. L.; McEwen, A. S.; Keszthelyi, L.

2000-10-01

Io has ~ 100 mountains [1] that, although often associated with patera [2], do not appear to be volcanic structures. The mountains are up to 16 km high [3] and are generally isolated from each other. We have performed finite-element simulations of the formation of these mountains, investigating several mountain building scenarios: (1) a volcanic construct due to heterogeneous resurfacing on a coherent, homogeneous lithosphere; (2) a volcanic construct on a faulted, homogeneous lithosphere; (3) a volcanic construct on a faulted, homogeneous lithosphere under compression induced by subsidence due to Io's high resurfacing rate; (4) a faulted, homogeneous lithosphere under subsidence-induced compression; (5) a faulted, heterogeneous lithosphere under subsidence-induced compression; and (6) a mantle upwelling beneath a coherent, homogeneous lithosphere under subsidence-induced compression. The models of volcanic constructs do not produce mountains similar to those observed on Io. Neither do those of pervasively faulted lithospheres under compression; these predict a series of tilted lithospheric blocks or plateaus, as opposed to the isolated structures that are observed. Our models show that rising mantle material impinging on the base of the lithosphere can focus the compressional stresses to localize thrust faulting and mountain building. Such faults could also provide conduits along which magma could reach the surface as is observed near several mountains. [1] Carr et al., Icarus 135, pp. 146-165, 1998.

WHAT IS KNOWN ON THE SUBJECT?: In general, the current studies of positive mental health use questionnaires or parts thereof. However, while these questionnaires evaluate aspects of positive mental health, they fail to measure the construct itself. WHAT DOES THIS PAPER ADD TO EXISTING KNOWLEDGE?: The widespread use and the lack of specific questionnaires for evaluating the positive mental health construct justify the need to measure the robustness of the Positive Mental Health Questionnaire. Also six factors are proposed to measure positive mental health. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: The availability of a good questionnaire to measure positive mental health in university students is useful not only to promote mental health but also to strengthen the curricula of future professionals. Introduction Nursing has a relevant role in managing mental health. It is important to identify and thereafter to enhance positive aspects of mental health among university nursing students. Aim The aim of the present study was to analyse the psychometric properties of the Positive Mental Health Questionnaire (PMHQ) in terms of reliability and validity using confirmatory factor analysis in a sample of university students. Method A cross-sectional study was carried out in a sample of 1091 students at 4 nursing schools in Catalonia, Spain. The reliability of the PMHQ was measured by means of Cronbach's alpha coefficient, and the test-retest stability was measured with the intraclass correlation coefficient (ICC). Confirmatory factor analysis was used to determine the validity of the factorial structure. Results Cronbach's alpha coefficient was satisfactory (>0.70) for four of the six subscales or dimensions and ranged from 0.54 to 0.79. ICC analysis was satisfactory for the six subscales or dimensions. The hypothesis was confirmed in the analysis of the correlations between subclasses and the overall scale, with the strongest correlations being found between the majority of the subscales and the overall scale. Confirmatory factor analysis showed that the model proposed for the factors fit the data satisfactorily. Discussion This scale is a valid and reliable instrument for evaluating positive mental health in university students. Implications for Practice A good questionnaire to measure positive mental health in university students is useful not only to promote mental health but also to strengthen the curricula of future professionals. © 2017 John Wiley & Sons Ltd.

Coherent 3D nanostructure of γ-Al{sub 2}O{sub 3}: Simulation of whole X-ray powder diffraction pattern

2017-02-15

The structure and nanostructure features of nanocrystalline γ-Al{sub 2}O{sub 3} obtained by dehydration of boehmite with anisotropic platelet-shaped particles were investigated. The original models of 3D coherent nanostructure of γ-Al{sub 2}O{sub 3} were constructed. The models of nanostructured γ-Al{sub 2}O{sub 3} particles were first confirmed by a direct simulation of powder X–Ray diffraction (XRD) patterns using the Debye Scattering Equation (DSE) with assistance of high-resolution transmission electron microscopy (HRTEM) study. The average crystal structure of γ-Al{sub 2}O{sub 3} was shown to be tetragonally distorted. The experimental results revealed that thin γ-Al{sub 2}O{sub 3} platelets were heterogeneous on a nanometer scalemore » and nanometer-sized building blocks were separated by partially coherent interfaces. The XRD simulation results showed that a specific packing of the primary crystalline blocks in the nanostructured γ-Al{sub 2}O{sub 3} particles with formation of planar defects on (001), (100), and (101) planes nicely accounted for pronounced diffuse scattering, anisotropic peak broadening and peak shifts in the experimental XRD pattern. The identified planar defects in cation sublattice seem to be described as filling cation non-spinel sites in existing crystallographic models of γ-Al{sub 2}O{sub 3} structure. The overall findings provided an insight into the complex nanostructure, which is intrinsic to the metastable γ-Al{sub 2}O{sub 3} oxide. - Highlights: • Thin plate-like crystallites of γ-Al{sub 2}O{sub 3} were obtained. • Models of 3D coherent nanostructure of γ-Al{sub 2}O{sub 3} were constructed. • Models were verified by simulating XRD patterns using the Debye Scattering Equation. • Specific broadening of XRD peaks was explained in terms of planar defects. • Primary crystalline blocks in γ-Al{sub 2}O{sub 3} are separated by partially coherent interfaces.« less

Ethics and mental illness research.

PubMed

Roberts, Laura Weiss

2002-09-01

There are many tasks ahead in the area of ethics and mental illness research. We face unknown challenges in psychiatric genetics projects, studies of psychopharmacological interventions in children, controversial scientific designs (e.g., symptom challenge, medication-free interval), and cross-disciplinary research incorporating goals and methods of health services, epidemiology, and social and behavioral science endeavors. Boundaries between innovative clinical practices and research-related experimentation will become increasingly difficult to distinguish, as will the roles between clinicians, clinical researchers, and basic scientists. Moreover, the institutions and systems in which research occurs are being rapidly and radically revised, raising new questions about oversight responsibilities and standards. Our ability to identify and respond to the ethical questions arising in this uncharted territory will depend on our willingness to self-reflect, to integrate the observations and insights of the past century, to think with great clarity, and to anticipate novel ethical problems that keep company with scientific advancements. It will also depend on data. Empirical study of ethical dimensions of human research is essential to anchor and attune the intuitions and theoretical constructs that we develop. Science and ethics have changed over the past 100 years, as they will over the next century. It is ironic that the ethical acceptability of psychiatric research is so much in question at this time, when it holds so much promise for advancing our understanding of mental illness and its treatment. The tension between the duty to protect vulnerable individuals and the duty to perform human science will continue to grow, as long as ethics and science are seen as separable, opposing forces with different aims championed by different heroes. The profession of psychiatry is poised to move toward a new, more coherent research ethics paradigm in which scientific and ethical issues are recognized as inextricably linked: science as a human activity carries complex ethical meanings and responsibilities, and ethics itself is subject to scrutiny and amenable to scientific inquiry. Building a broader, more versatile, and more effective repertoire of safeguards will be increasingly important, and safeguards, in this view, represent a modest price for the privilege of studying serious illnesses--diseases that cause grave suffering and yet are a source of both vulnerability and strength. In this paradigm, attention to ethics safeguards is no longer understood as a barrier to scientific advancement, but rather as the means by which psychiatric research may be conducted with broad societal support, honorably and, ultimately, with the expectation of bringing benefit to millions of people with mental illness.
