Consciousness and working memory: Current trends and research perspectives.

PubMed

Velichkovsky, Boris B

2017-10-01

Working memory has long been thought to be closely related to consciousness. However, recent empirical studies show that unconscious content may be maintained within working memory and that complex cognitive computations may be performed on-line. This promotes research on the exact relationships between consciousness and working memory. Current evidence for working memory being a conscious as well as an unconscious process is reviewed. Consciousness is shown to be considered a subset of working memory by major current theories of working memory. Evidence for unconscious elements in working memory is shown to come from visual masking and attentional blink paradigms, and from the studies of implicit working memory. It is concluded that more research is needed to explicate the relationship between consciousness and working memory. Future research directions regarding the relationship between consciousness and working memory are discussed. Copyright © 2017 Elsevier Inc. All rights reserved.

Health among hospital employees in Europe: a cross-national study of the impact of work stress and work control.

PubMed

Pisljar, Tjasa; van der Lippe, Tanja; den Dulk, Laura

2011-03-01

This article analyses the effect of working conditions on the health of hospital employees across Europe. Hospital employees often have demanding jobs that increase their stress levels and, consequently, their risk of health problems. Work control - typified by employee autonomy and working time flexibility - helps them cope with high levels of work stress. Researchers have traditionally studied the relationship between working conditions, coping strategies and occupational health from an individual perspective. We argue that the individual work-health relationship is closely connected with the social and institutional context. This study explores how work stress and work control influence the health of hospital employees and aims to understand cross-country differences in this respect. Using data on over 1500 hospital employees who participated in the study 'Quality of work and life in a changing Europe' (2007) in eight European countries, we used ordinal regression analyses to test a range of hypotheses. The results show that work stress has a negative effect on the health of hospital employees, while work control is not found to have any effect on their health. Comparative analyses reveal that the effects of working conditions on health vary across European countries. While working overtime is more closely related to poorer health in Eastern European countries, we found evidence of a positive relationship between job autonomy and health in Western Europe only, indicating that circumstances in the working environment have differing effects on employee health in Eastern and Western Europe.

Exploring the Link among State of Mind Concerning Childhood Attachment, Attachment in Close Relationships, Parental Bonding, and Psychopathological Symptoms in Substance Users.

2016-01-01

In the present study, we have explored the link among styles of attachment and psychopathology in drug users. We know that insecure attachment predisposes the individuals the development of drug-addiction and psychopathological symptoms. However, we do not know which attachment is more frequent in drug users and which is related to particular psychopathological symptoms. The aim of the present work is to explore the relationship between childhood attachment state of mind, attachment in close relationships, parental bonding and psychopathology in sample of Italian substance users. We explored, in a sample of 70 drug users and drug-addicted patients, the childhood attachment state of mind measured by the Adult Attachment Interview, the attachment in close relationships by the Relationship Questionnaire and parental bonding measured by the Parental Bonding Instrument. The Symptom Check-List-90-R (SCL-90-R) measured psychopathological symptoms. We found that parental bonding, rather than state of mind concerning childhood attachment or attachment in close relationships, is related to the psychopathological manifestation of anxiety, hostility, depression, and paranoid ideation in the sample. The latter occurs frequently in our sample, independent of state of mind concerning child attachment, attachment in close relationships, and parental bonding, suggesting its role either as a factor that favors a bad image of the participants' own relationships or as a direct effect of consuming drugs. These results have clinical implications on suggesting ways of interventions that prevent drug-addiction, which should include the evaluation of attachment in the prodromic phases of substance use onset or rehabilitation programs to prevent and manage psychotic-like symptoms.

Psychosocial work characteristics and social support as predictors of SF-36 health functioning: the Whitehall II study.

PubMed

Stansfeld, S A; Bosma, H; Hemingway, H; Marmot, M G

1998-01-01

To assess whether work characteristics and social support are predictors of physical, psychological, and social functioning. Work characteristics (Karasek and Siegrist models) and social support at baseline were used to predict health functioning measured by the SF-36 General Health Survey 5 years later in a prospective cohort study of 10,308 British male and female civil servants. Effort-reward imbalance and negative aspects of close relationships predicted poor physical, psychological, and social functioning after adjustment for the potential confounding effects of age, employment grade, baseline ill health, and negative affectivity. These psychosocial characteristics seem to act in a similar way in the healthy and those with existing illness. Psychological demands at work in women, and low confiding/emotional support in men, also predicted poor functioning. Etiologically. these effects are not mediated through health-related behaviors. Negative aspects of work (high demands and effort-reward imbalance) and negative aspects of close relationships are independent powerful predictors of poor health functioning. They may have an etiological role, which is independent of baseline illness.

Is mind-mindedness trait-like or a quality of close relationships? Evidence from descriptions of significant others, famous people, and works of art.

PubMed

Meins, Elizabeth; Fernyhough, Charles; Harris-Waller, Jayne

2014-03-01

The four studies reported here sought to explore the nature of the construct of mind-mindedness. In Study 1, involving 37 mothers of 5- to 8-year-old children, mothers' verbal mind-minded descriptions of their children were positively correlated with their mind-minded descriptions of their current romantic partner. Participants in Studies 2 (N=114), 3 (N=173), and 4 (N=153) were young adults who provided written descriptions of: a close friend and their current romantic partner (Study 2); two specified famous people, two works of art, and a close friend (Study 3); a specified famous person, a famous person of the participant's choice, and a close friend (Study 4). Study 2 obtained paper-and-pen written descriptions, whereas participants completed descriptions in electronic format in Studies 3 and 4. Mind-minded descriptions of friends and partners were positively correlated, but there was no relation between mind-minded descriptions of a friend and the tendency to describe famous people or works of art in mind-minded terms. Levels of mind-mindedness were higher in descriptions of friends compared with descriptions of famous people or works of art. Administration format was unrelated to individuals' mind-mindedness scores. The results suggest that mind-mindedness is a facet of personal relationships rather than a trait-like quality.

Parent-Adolescent Relationship Qualities, Internal Working Models, and Styles as Predictors of Adolescents’ Observed Interactions with Friends

PubMed Central

Shomaker, Lauren B.; Furman, Wyndol

2010-01-01

This study examined how current parent-adolescent relationship qualities and adolescents’ representations of relationships with parents were related to friendship interactions in 200 adolescent-close friend dyads. Adolescents and friends were observed discussing problems during a series of structured tasks. Negative interactions with mothers were significantly related to adolescents’ greater conflict with friends, poorer focus on tasks, and poorer communication skills. Security of working models (as assessed by interview) was significantly associated with qualities of friendship interactions, whereas security of attachment styles (as assessed by questionnaire) was not. More dismissing (vs. secure) working models were associated with poorer focus on problem discussions and weaker communication skills with friends, even after accounting for gender differences and current parent-adolescent relationship qualities. We discuss possible mechanisms for the observed links between dimensions of parent-adolescent relationships and friendships. We also consider methodological and conceptual differences between working model and style measures of attachment representations. PMID:20174459

Interpersonal mechanisms linking close relationships to health.

PubMed

Pietromonaco, Paula R; Collins, Nancy L

2017-09-01

Close relationships play a vital role in human health, but much remains to be learned about specific mechanisms of action and potential avenues for intervention. This article provides an evaluation of research on close relationships processes relevant to health, drawing on themes from major relationship science theories to present a broad conceptual framework for understanding the interpersonal processes and intrapersonal pathways linking relationships to health and disease outcomes. The analysis reveals that both social connection and social disconnection broadly shape biological responses and behaviors that are consequential for health. Furthermore, emerging work offers insights into the types of social dynamics that are most consequential for health, and the potential pathways through which they operate. Following from this analysis, the authors suggest several research priorities to facilitate the translation of discoveries from relationship science into relationship-based interventions and public health initiatives. These priorities include developing finer grained theoretical models to guide research, the systematic investigation of potential mediating pathways such as dyadic influences on health behavior and physiological coregulation, and taking into account individual differences and contextual factors such as attachment style, gender, socioeconomic status, and culture. In addition, a pressing need exists for laboratory and field research to determine which types of interventions are both practical and effective.

Intimacy and Relationship Processes in Couples’ Psychosocial Adaptation to Cancer

PubMed Central

Manne, Sharon; Badr, Hoda

2015-01-01

The authors highlighted the importance of viewing cancer from a relationship perspective. This perspective not only considers the marital relationship as a resource that individual partners draw upon but also highlights the importance of focusing attention onto the relationship and engaging in communication behaviors aimed at sustaining and/or enhancing the relationship during stressful times. On the basis of existing conceptualizations, empiric research on couples and cancer, and the authors’ perspective on the literature, they formulated the relationship intimacy model of couples’ psychosocial adaptation to cancer as a first step toward building a framework for researchers and clinicians to inform their work in this area. The model proposes that patients and their partners engage in behaviors that either promote or undermine the level of closeness in their relationship and that the closeness of the marital relationship is an important determinant of patient and partner psychologic adaptation to cancer. Preliminary data from a couples’ intimacy-enhancing intervention for breast cancer patients and their partners supported the model. Of the 25 couples who consented to participate in the intervention and completed the preintervention surveys, 15 couples completed all 5 sessions, and 12 couples completed the follow-up survey. The current results suggested that the intervention improved patient and partner perceptions of the closeness of their relationship and reduced their distress. The authors also discuss limitations of the relationship intimacy model as well as future directions for empiric and clinical research on couples’ psychosocial adaptation to cancer. PMID:18428202

The relationship between different exercise modes and visuospatial working memory in older adults: a cross-sectional study.

2016-01-01

The purpose of the study was to investigate the relationship between different exercise modes and visuospatial working memory in healthy older adults. A cross-sectional design was adopted. A total of 111 healthy older adults were enrolled in the study. They were classified by the exercise-related questionnaire to be in an open-skill group, closed-skill group or sedentary group. In experiment 1, the participants performed a visuospatial working memory task. The results indicated that both closed-skill (p < 0.05) and open-skill (p < 0.01) groups reached a higher accuracy than the sedentary group. Experiment 2 examined whether the exercise-induced benefit of working memory was manifested in passive maintenance or active manipulation of working memory which was assessed by visuospatial short-term memory task and visuospatial mental rotation task, respectively. The results showed that the open-skill (p < 0.01) group was more accurate than the sedentary group in the visuospatial short-term memory task, whereas the group difference in the visuospatial mental rotation task was not significant. These findings combined to suggest that physical exercise was associated with better visuospatial working memory in older adults. Furthermore, open-skill exercises that demand higher cognitive processing showed selective benefit for passive maintenance of working memory.

Marcus, Dawn A; Richards, Karen Lee; Chambers, Janet F; Bhowmick, Amrita

2013-09-01

Fibromyalgia is frequently associated with impairments in activities of daily living and work disability. Limited data have investigated the impact of fibromyalgia on relationships with family and friends. This exploratory study was designed to survey a large community sample of adults with fibromyalgia about the impact on the spouse/partner, children and close friends. A 40-question, multiple-choice survey was made available online for a two-month period, with potential participants recruited through fibromyalgia and migraine community websites. Items included questions about demographics, fibromyalgia symptoms, comorbid mood disturbance and relationship impact, including the Relationship Assessment Scale. The survey was completed by 6,126 adults who had been diagnosed with fibromyalgia. Using updated diagnostic criteria from the American College of Rheumatology, 91% satisfied the criteria for fibromyalgia (Fibromyalgia Severity score ≥13 and pain ≥3 months). Half of participants endorsed that fibromyalgia had mildly to moderately damaged relationship(s) with their spouse(s)/partner(s) or contributed to a break-up with a spouse or partner. Half of participants scored as not being satisfied with their current spouse/partner relationship, with satisfaction negatively affected by the presence of mood disturbance symptoms and higher fibromyalgia severity. Relationships with children and close friends were also negatively impacted for a substantial minority of participants. In addition to physical impairments that are well documented among individuals with fibromyalgia, fibromyalgia can result in a substantial negative impact on important relationships with family and close friends.

Destructive de-energizing relationships: How thriving buffers their effect on performance.

PubMed

Gerbasi, Alexandra; Porath, Christine L; Parker, Andrew; Spreitzer, Gretchen; Cross, Rob

2015-09-01

In this paper, we establish the relationship between de-energizing relationships and individual performance in organizations. To date, the emphasis in social network research has largely been on positive dimensions of relationships despite literature from social psychology revealing the prevalence and detrimental impact of de-energizing relationships. In 2 field studies, we show that de-energizing relationships in organizations are associated with decreased performance. In Study 1, we investigate how de-energizing relationships are related to lower performance using data from 161 people in the information technology (IT) department of an engineering firm. In Study 2, in a sample of 439 management consultants, we consider whether the effects of de-energizing relationships on performance may be moderated by the extent to which an individual has the psychological resource of thriving at work. We find that individuals who are thriving at work are less susceptible to the effects of de-energizing relationships on job performance. We close by discussing implications of this research.

The study aim was to determine relationships between mechanical variables in the one-repetition maximum (1RM) traditional bench press (TBP) and close-grip bench press (CGBP). Twenty resistance-trained men completed a TBP and CGBP 1RM. The TBP was performed with the preferred grip; the CGBP with a grip width of 95% biacromial distance. A linear position transducer measured: lift distance and duration; work; and peak and mean power, velocity, and force. Paired samples t-tests (p < 0.05) compared the 1RM and mechanical variables for the TBP and CGBP; effect sizes (d) were also calculated. Pearson's correlations (r; p < 0.05) computed relationships between the TBP and CGBP. 1RM, lift duration, and mean force were greater in the TBP (d = 0.30-3.20). Peak power and velocity was greater for the CGBP (d = 0.50-1.29). The 1RM TBP correlated with CGBP 1RM, power, and force (r = 0.685-0.982). TBP work correlated with CGBP 1RM, lift distance, power, force, and work (r = 0.542-0.931). TBP power correlated with CGBP 1RM, power, force, velocity, and work (r = 0.484-0.704). TBP peak and mean force related to CGBP 1RM, power, and force (r = 0.596-0.980). Due to relationships between the load, work, power, and force for the TBP and CGBP, the CGBP could provide similar strength adaptations to the TBP with long-term use. The velocity profile for the CGBP was different to that of the TBP. The CGBP could be used specifically to improve high-velocity, upper-body pushing movements.

The green eyed monster in the bottle: Relationship contingent self-esteem, romantic jealousy, and alcohol-related problems.

PubMed

DiBello, Angelo M; Rodriguez, Lindsey M; Hadden, Benjamin W; Neighbors, Clayton

2015-10-01

Previous research suggests that both jealousy and relationship contingent self-esteem (RCSE) are related to alcohol use and alcohol-related problems. No work, however, has examined these two constructs together as they relate to motives for alcohol use and alcohol-related problems. The current study aims to build upon emerging literature examining different types of jealousy (i.e., emotional, cognitive, and behavioral), relationship quality (i.e., satisfaction, commitment, closeness), RCSE, and alcohol use. More specifically, the current study aimed to examine the associations between RCSE and drinking to cope and RCSE and alcohol-related problems, in the context of the different types of jealousy. Moreover, the current study aimed to assess whether the associations between RCSE, jealousy, and drinking outcomes vary as a function of relationship quality. Two hundred and seventy seven individuals (87% female) at a large southern university participated in the study. They completed measures of RCSE, relationship satisfaction, commitment, closeness, and jealousy as well as alcohol-related outcomes. Using PROCESS, moderated mediational analyses were used to evaluate different types of jealousy as mediators of the association between RCSE and drinking to cope/alcohol-related problems. Further, we aimed to examine whether relationship quality moderated the association between RCSE and jealousy in predicting alcohol-related variables. Results indicated that cognitive jealousy mediated the association between both RCSE and drinking to cope and RCSE and alcohol-related problems. Further, relationship satisfaction, commitment, and closeness were all found to moderate the association between RSCE and cognitive jealousy such that at lower, but not higher levels of satisfaction, commitment, and closeness, cognitive jealousy mediated the association between RCSE and drinking to cope and RCSE and alcohol-related problems.

The Development of Altruism with Special Reference to Human Relationships: A 10-Stage Theory.

PubMed

Ma, Hing Keung

2017-01-01

All human relationships involve some form of cost and benefit and altruism forms the foundation upon which human relationships are built. In this paper, a taxonomy of human relationships in terms of altruism was constructed. In the proposed taxonomy, human relationships are categorized into three major groups: primary group, secondary group, and tertiary group. The primary group consists of members that are very closely related to each other either by genetic relatedness (e.g., parents, siblings, and cousins) or social relatedness (e.g., mate and close friends) or both. The secondary group consists of members that are socially related but also less closely related with each other (e.g., people of the same political or religious group, teachers, mentors, acquaintances, neighbors, working colleagues, and strangers). Lastly, the tertiary group consists of members of other species. A 10-stage theory of altruism with special reference to human relationships is proposed. The affective, cognitive, and relationship aspects of each stage are delineated in details. There are two developmental principles of altruism. The first principle states that the development of altruism follows the 10-stage theory and moves from Stage 1: Egoism toward the higher stages of altruism slowly. The second developmental principle states that the taxonomy of human relationships is valid at any stage of altruism development. In other words, people at any stage of altruism are more altruistic toward their kin and mate, and then close friends, extended family members, and so on. They are least altruistic toward enemies and members of non-human species. In summary, the proposed developmental principle of altruism and human relationships is logical and robust. It is formulated based on the major developmental and social psychological theories. The theory has the potential in providing a useful framework for future studies on the development and evolution of human relationships.

Seeking to explain mixed empirical findings regarding the buffering effect of social support on work-based stress-strain relations, we posit that whether an increase in the level of support received buffers or exacerbates the harmful effects of workload on employee health and well-being is contingent upon the general pattern characterizing an employee supportive exchanges across his/her close relationships. Specifically, we propose that the buffering effect of receiving social support depends on whether the employee perceives his/her social exchanges as reciprocal (support given equals support received), under-reciprocating (support given exceeds support received), or over-reciprocating (support received exceeds support given). Based on longitudinal data collected from a random sample of blue-collar workers, our findings support our predictions, indicating that the buffering effect of social support on the relationship between work hours (on the one hand) and employee health and well-being (on the other) varies as a function of the pattern of exchange relations between an employee and his/her close support providers.

Evolving Relationship Structures in Multi-sourcing Arrangements: The Case of Mission Critical Outsourcing

NASA Astrophysics Data System (ADS)

Heitlager, Ilja; Helms, Remko; Brinkkemper, Sjaak

Information Technology Outsourcing practice and research mainly considers the outsourcing phenomenon as a generic fulfilment of the IT function by external parties. Inspired by the logic of commodity, core competencies and economies of scale; assets, existing departments and IT functions are transferred to external parties. Although the generic approach might work for desktop outsourcing, where standardisation is the dominant factor, it does not work for the management of mission critical applications. Managing mission critical applications requires a different approach where building relationships is critical. The relationships involve inter and intra organisational parties in a multi-sourcing arrangement, called an IT service chain, consisting of multiple (specialist) parties that have to collaborate closely to deliver high quality services.

2015-12-01

Although back pain (BP) is a very common cause for sickness absence, most people stay at work during BP episodes. Existing knowledge on the factors influencing the decision to stay at work despite pain is limited. The aim of this study was to explore challenges for coping with BP at work and decisive factors for work attendance among workers with high physical work demands. Three focus groups (n = 20) were conducted using an explorative inductive method. Participants were public-employed manual workers with high physical work demands. All had personal BP experience. Thematic analysis was used for interpretation. Results were matched with the Flags system framework to guide future recommendations. Workers with BP were challenged by poor physical work conditions and a lack of supervisor support/trust (i.e. lack of adjustment latitude). Organization of workers into teams created close co-worker relationships, which positively affected BP coping. Workers responded to BP by applying helpful individual adjustments to reduce or prevent pain. Traditional ergonomics was considered inconvenient, but nonetheless ideal. When pain was not decisive, the decision to call in sick was mainly governed by workplace factors (i.e. sick absence policies, job strain, and close co-workers relationships) and to a less degree by personal factors. Factors influencing BP coping at work and the decision to report sick was mainly governed by factors concerning general working conditions. Creating a flexible and inclusive working environment guided by the senior management and overall work environment regulations seems favourable.

Positive Psychology in Context: Effects of Expressing Gratitude in Ongoing Relationships Depend on Perceptions of Enactor Responsiveness

Recent correlational evidence implicates gratitude in personal and relational growth, for both members of ongoing relationships. From these observations, it would be tempting to prescribe interpersonal gratitude exercises to improve relationships. In this experiment, couples were randomly assigned to express gratitude over a month, or to a relationally-active control condition. Results showed modest effects of condition on personal and relational well-being. However, those whose partners were perceived as being particularly responsive when expressing gratitude at the initial lab session showed greater well-being across a range of outcomes, whereas this was not so for people in the control condition. Notably, evidence raises concerns about the effectiveness of artificial injections of gratitude when the partner is perceived to be low in responsiveness. Given the importance of close relationships, this work highlights the need for more theory-driven basic research tested in context before assuming what appears to work naturally will also work artificially.

Background The interaction between physicians and the pharmaceutical industry influences physicians' attitudes and prescribing behavior. Although largely studied in the US, this topic has not been well studied in resource-poor settings, where a close relationship between physicians and industry still exists. Objective To describe physician interactions with and attitudes towards the pharmaceutical industry in a public general hospital in Lima, Peru. Design Descriptive, cross-sectional study through an anonymous, self-filled questionnaire distributed among faculty and trainee physicians of five different clinical departments working in a Peruvian public general hospital. A transcultural validation of an existing Spanish questionnaire was performed. Exposure to marketing activities, motivations to contact pharmaceutical representatives and attitudes towards industry were studied. Collected data was analyzed by degree of training, clinical department, gender and teaching status. Attitudes were measured on a four-point LIKERT scale. Results 155 physicians completed the survey, of which 148 were included in the study sample. 94.5% of attending physicians reported ongoing encounters with pharmaceutical representatives. The most common industry-related activities were receiving medical samples (91.2%), promotional material (87.8%) and attending meetings in restaurants (81.8%). Respondents considered medical samples and continuing medical education the most ethically acceptable benefits. We found significant differences between attendings and residents, and teaching and non-teaching attendings. An association between the amount of encounters with pharmaceutical representatives, and attitudes towards industry and acceptance of medical samples was found. Conclusions A close physician-industry relationship exists in the population under study. The contact is established mainly through pharmaceutical representatives. Medical samples are the most received and ethically accepted benefit. The attitudes of physicians on the ethical standards of acceptance of medical samples and other benefits are closely related with their exposure to the pharmaceutical industry. Future studies could explore the motivations of physicians working in resource-poor settings to maintain a close relationship with industry. PMID:24978481

Family relationships and the development of social competence in adolescence.

PubMed

Brennan, J L

1993-01-01

Resilient adolescents are notable for their social competence, which enables them to form and maintain close relationships. The evidence is that adolescents' social competence is derived from their experience of close relationships within their family. On the basis of structured interviews, adolescents' working models of attachments can be categorized into secure, dismissive, or pre-occupied. These attachment styles are associated with very divergent beliefs about the self and others, with differing patterns of emotion regulation and with differing risk profiles for maladjustment. Parenting styles and family relationships appear to have considerable influence on attachment behaviour. Further evidence for the importance of the family comes from research on ego development. Family level behavioural patterns have been discerned from family research interviews which are associated with stagnation or advancement in ego development during adolescence. Though the results suggest causal connections, the direction of effects is far from clear. Longitudinal research underpins the importance of childhood temperament as a contributing factor to the quality of the family environment that the child and then adolescent experiences.

Sexual Closeness Discrepancies: What They Are and Why They Matter for Sexual Well-Being in Romantic Relationships.

Frost, David M; McClelland, Sara I; Dettmann, Miranda

2017-11-01

This study examined the impact of sexual closeness on sexual well-being. We developed a nuanced and multifaceted conceptualization of sexual closeness in the form of a constellation of ideal sexual closeness with a partner, actual sexual closeness, and the discrepancy between the two. Data were obtained from a diverse sample of N = 619 participants who took part in the Lives and Relationships Study: A longitudinal survey of men and women in relationships living in the U.S. and Canada. Increases in sexual closeness discrepancies over a period of 1 year predicted concomitant decreases in two indicators of sexual well-being: sexual satisfaction and orgasm frequency evaluations. Decreases in sexual closeness discrepancies resulted in improvement in sexual well-being. Individuals who reported no sexual closeness discrepancies and experienced no changes in sexual closeness discrepancies tended to have the highest levels of sexual well-being. Importantly, sexual closeness discrepancies were robust predictors of sexual well-being, above and beyond individuals' actual sexual closeness, general relationship closeness, and other demographic and relationship characteristics known to be associated with sexual well-being. The present findings demonstrate that how close people feel sexually to their relationship partners is part of a general constellation of factors related to relationship closeness that, only when considered together, sufficiently explain the ways in which experiences of closeness impact sexual well-being in romantic relationships.

Very limited research has been undertaken on sex workers' personal romantic relationships and the impact the nature of their work has on their relationships. This exploratory study aimed to explore the impact sex work has on women's personal romantic relationships and the use of mental separation as a coping mechanism to balance the two aspects of their lives. Fifty-five women working in the indoor sex industry in Melbourne, Australia, were recruited to complete a self-report questionnaire about various aspects of their work, including the impact of sex work on their personal relationships. Questionnaires were completed anonymously and included both closed and open-ended questions. A further six women were interviewed to 'member check' the accuracy of the questionnaire findings. Most women (78%) reported that, overall, sex work affected their personal romantic relationships in predominantly negative ways, mainly relating to issues stemming from lying, trust, guilt and jealousy. A small number of women reported positive impacts from sex work including improved sexual self-esteem and confidence. Just under half of women were in a relationship at the time of the study and, of these, 51% reported their partner was aware of the nature of their work. Seventy-seven percent of single women chose to remain single due to the nature of their work. Many women used mental separation as a coping mechanism to manage the tensions between sex work and their personal relationships. Member checking validated the accuracy of the questionnaire data. This exploratory study identified a number of ways in which sex work impacts negatively on women's personal romantic relationships. The findings of this study support the need for further studies to be undertaken to determine if the findings are reflected in a larger, more representative sample of Australian sex workers and should be considered in the context of any future intervention and support programs aimed at addressing the tensions sex workers experience between their work and personal relationships. Greater public awareness and education programs aimed at addressing the negative stigma associated with the sex industry may go some way towards easing the issues faced by women in their personal relationships.

2013-11-01

The aim of this study was to examine the relationship between vocational rehabilitation services provided and work outcomes among people with cerebral palsy (CP), taking in to account demographic characteristics. From the US Department of Education Rehabilitation Service Administration Case Service Report (RSA-911) database, data from 3162 individuals with CP (1820 males [57.6%] and 1342 females [42.4% age range 16-54 y) whose cases were closed in 2009, were used in this study. A total of 1567 cases (49.6%) were closed with clients being categorized as 'successful employment' and 1595 cases (50.4%) were closed with clients being classified as unemployed. Multivariate logistic regression was used to examine the relationship between services provided and work outcomes with regard to demographic characteristics. Males aged between 26 and 54 years old with higher education attainment were more likely to be employed. Individuals receiving disability benefits were less likely to be employed. After controlling for the effect of demographic and work disincentive variables, five vocational rehabilitation services significantly predicted employment outcomes (p<0.05), including (1) on-the-job training; (2) job placement assistance; (3) on-the-job support; (4) maintenance services; and (5) rehabilitation technology. Medical and health professionals need to be aware of vocational rehabilitation agencies as a resource for providing medical, psychological, educational, and vocational interventions for adults with CP to help them maximize their employability, to address their much needed work adjustment skills, to establish independent living, and to eventually reach their full potential in participation in society. © 2013 Mac Keith Press.

Team work is considered a central component of palliative care. Within this comparatively young field of medicine, the emergence of new institutions (eg, palliative care units) highlights the challenge of establishing a completely new team. This study focuses on the factors, which enhance both the success and outcome criteria of good team work from the perception of team members in a palliative care unit. The palliative care team at the University Hospital of Aachen (n = 19) was interviewed 1 year after the unit's startup by the means of semistructured interviews. Interview texts were analysed using qualitative content analysis. Factors crucial to cooperation in the team members' views were close communication, team philosophy, good interpersonal relationships, high team commitment, autonomy and the ability to deal with death and dying. Moreover, close communication was by far the most frequently mentioned criteria for cooperation. Team performance, good coordination of workflow and mutual trust underpin the evaluation of efficient team work. Inefficient team work is associated with the absence of clear goals, tasks and role delegation, as well as a lack of team commitment. In a new team, close communication is particularly important for staff as they reorientate themselves to the dynamics of a new peer group. The results confirm the overwhelming importance of clarity, commitment and close, positive exchange among team members for successful team work.

Frequent demands from others in relationships are associated with worse physiological and health outcomes. The present research investigated 2 potential moderators of the relationship between frequency of demands from one's family and inflammatory profiles among adolescents: (a) closeness of adolescents' relationships with their families, and (b) the frequency with which adolescents provided help to their families. Two hundred thirty-four adolescents, ages 13-16 (Mage = 14.53; 47.83% male), completed a daily dairy in which they reported on the frequency of demands made by family members. They were also interviewed about the closeness of their family relationships and reported in the daily diary on how frequently they provided help to their families. Adolescents also underwent a blood draw to assess low-grade inflammation and proinflammatory cytokine production in response to bacterial stimulation. More frequent demands from family predicted higher levels of low-grade inflammation and cytokine production in response to bacterial stimulation in adolescents. Family closeness moderated the relationship between frequent demands and stimulated cytokine production such that more frequent demands predicted higher cytokine production among adolescents who were closer to their families. Furthermore, frequency of providing help moderated the relationship between frequent demands and both low-grade inflammation and stimulated cytokine production, such that more frequent demands predicted worse inflammatory profiles among adolescents who provided more help to their families. These findings build on previous work on family demands and health to show under what circumstances family demands might have a physiological cost.

2016-12-01

The purpose of this study is to examine the potential relationship between tonic accommodation (TA), near work induced TA-adaptation and the steady state closed-loop accommodation response (AR). Forty-two graduate students participated in the study. Various aspects of their accommodation system were objectively measured using an open-field infrared auto-refractor (Grand Seiko WAM-5500). Tonic accommodation was assessed in a completely dark environment. The association between TA and closed-loop AR was assessed using linear regression correlations and t-test comparisons. Initial mean baseline TA was 1.84diopter (D) (SD±1.29D) with a wide distribution range (-0.43D to 5.14D). For monocular visual tasks, baseline TA was significantly correlated with the closed-loop AR. The slope of the best fit line indicated that closed-loop AR varied by approximately 0.3D for every 1D change in TA. This ratio was consistent across a variety of viewing distances and different near work tasks, including both static targets and continuous reading. Binocular reading conditions weakened the correlation between baseline TA and AR, although results remained statistically significant. The 10min near reading task with a 3D demand did not reveal significant near work induced TA-adaptation for either monocular or binocular conditions. Consistently, the TA-adaptation did not show any correlation with AR during reading. This study found a strong association between open-loop TA and closed-loop AR across a variety of viewing distances and different near work tasks. Difference between the correlations under monocular and binocular reading condition suggests a potential role for vergence compensation during binocular closed-loop AR. Copyright © 2016 Elsevier Ltd.

Familism and Psychological Health: The Intervening Role of Closeness and Social Support

Campos, Belinda; Ullman, Jodie B.; Aguilera, Adrian; Schetter, Christine Dunkel

2014-01-01

Familism, a cultural value that emphasizes warm, close, supportive family relationships and that family be prioritized over self, has been associated with psychological health. The goal of this work was to fill a gap in the literature on how familism contributes to psychological health. Drawing from conceptual links between familism and close relationship processes, we hypothesized that familism contributes to better psychological health by facilitating closeness and social support. A university sample of U.S. women and men of Latino (n = 173), European (n = 257), and Asian (n = 642) cultural backgrounds completed measures of familism, closeness to family members, general perceived social support, and psychological health as indexed by perceived stress, general mental health, and depressive symptoms. Structural equation multiple-group modeling analyses found direct effects of familism on closeness to family members and perceived social support and an indirect effect of familism on better psychological health via greater closeness to family members and greater perceived social support. These effects did not differ by cultural background. Consistent with previous research, however, Latinos reported the highest levels of familism of the three cultural groups, and women reported higher familism and support as well as poorer psychological health than men. Discussion is focused on the implications of these findings for understanding the association of familism with psychological health and the relevance of the familism construct for diverse U.S. groups.

The existential function of close relationships: introducing death into the science of love.

2003-01-01

Originally, terror management theory proposed two psychological mechanisms in dealing with the terror of death awareness-cultural worldview validation and self-esteem enhancement. In this article, we would like to promote the idea of close relationships as an additional death-anxiety buffering mechanism and review a growing body of empirical data that support this contention. Based on a comprehensive analysis of the sociocultural and personal functions of close relationships, we formulate two basic hypotheses that have received empirical support in a series of experimental studies. First, death reminders heighten the motivation to form and maintain close relationships. Second, the maintenance of close relationships provides a symbolic shield against the terror of death, whereas the breaking of close relationships results in an upsurge of death awareness. In addition, we present empirical evidence supporting the possibility that close relationships function as a related yet separate mechanism from the self-esteem and cultural worldview defenses.

The social regulation of emotion and updating negative contents of working memory.

PubMed

Flores, Luis E; Berenbaum, Howard

2017-06-01

The social regulation of emotion reduces negative affect and may also help remove negative contents from working memory. The present studies investigated whether the social regulation of emotion (in the form of handholding) altered the ability to update negative contents from working memory and whether a person's level of desired emotional closeness moderated this effect. In each of 2 studies, an unselected sample of undergraduate students completed an emotional working memory task that measured the ability to remove irrelevant information from working memory and a self-report questionnaire measuring their level of desired emotional closeness. In Study 1 (N = 109), the task consisted only of negative images, and each participant performed half of the task while holding someone's hand and the other half while not holding someone's hand. Study 2 (N = 195) included a few changes (e.g., using both negative and neutral images, altering the control condition to consist of holding a stress ball, using a between-participants design, measuring comfort with handholding) to address a few potential alternative explanations. Overall, there appeared to be a better ability to update negative contents of working memory in the handholding condition of each study than the control condition among people with high desired emotional closeness but not among people with low desired emotional closeness. The present findings provide evidence that the social regulation of emotion can facilitate the removal of irrelevant negative contents of working memory. This process may be one way in which supportive relationships protect against psychological distress. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Interpersonal identity formation in conversations with close friends about dating relationships.

PubMed

Morgan, Elizabeth M; Korobov, Neill

The present study explores how close same-sex friendship groups participate in the co-construction of identities in the interpersonal domain during young adulthood. Participants included 24 same-sex college student friendship triads (12 male and 12 female; 72 total participants) who took part in semi-structured group interviews that elicited stories about conversations with their friends about dating relationship problems. Qualitative thematic analysis revealed five common responses to dating problems evidencing identity work in the context of friends' conversations. These responses included relating the issue to one's own experiences, providing validation and encouragement, joking about the problem, offering advice, and providing concrete instrumental support. Results are interpreted with regard to gender differences and similarities as well as the social context of college and developmental context of emerging adulthood. The findings identify ways in which young adults are actively co-constructing and re-evaluating their interpersonal identities within conversations with close same-sex friends.

Affectionate Touch to Promote Relational, Psychological, and Physical Well-Being in Adulthood: A Theoretical Model and Review of the Research.

PubMed

Jakubiak, Brittany K; Feeney, Brooke C

2017-08-01

Throughout the life span, individuals engage in affectionate touch with close others. Touch receipt promotes well-being in infancy, but the impacts of touch in adult close relationships have been largely unexplored. In this article, we propose that affectionate touch receipt promotes relational, psychological, and physical well-being in adulthood, and we present a theoretical mechanistic model to explain why affectionate touch may promote these outcomes. The model includes pathways through which touch could affect well-being by reducing stress and by promoting well-being independent of stress. Specifically, two immediate outcomes of affectionate touch receipt-relational-cognitive changes and neurobiological changes-are described as important mechanisms underlying the effects of affectionate touch on well-being. We also review and evaluate the existing research linking affectionate touch to well-being in adulthood and propose an agenda to advance research in this area. This theoretical perspective provides a foundation for future work on touch in adult close relationships.

Aims Recent empirical studies investigating "study addiction" have conceptualized it as a behavioral addiction, defined within the framework of work addiction. This study is the first attempt to examine the longitudinal relationship between study addiction and work addiction. Methods The Bergen Study Addiction Scale (BStAS), the Bergen Work Addiction Scale (BWAS), and the Ten-Item Personality Inventory were administered online together with questions concerning demographics and study-related variables in two waves. In Wave 1, a total of 2,559 students in Norway and 2,177 students in Poland participated. A year later, in Wave 2, 379 Norwegians and 401 Polish who began to work professionally completed the survey. Results The intraclass correlation between BStAS and BWAS revealed that the scores were somewhat related; however, the relationship was slightly weaker than the temporal stability of both constructs. In the Norwegian sample, scoring higher on neuroticism and lower on learning time outside educational classes in Wave 1 was positively related to work addiction in Wave 2, whereas gender was unrelated to work addiction in Wave 2 when controlling for other studied variables in either samples. Conclusion Study addiction and work addiction appear to be closely related suggesting that the former may be a precursor for (or an early form of) the latter.

2014-01-01

This study examined whether adolescents’ closeness to adoptive parents (APs) predicted attachment styles in close relationships outside their family during young adulthood. In a longitudinal study of domestic infant adoptions, closeness to adoptive mother and adoptive father was assessed in 156 adolescents (M = 15.7 years). Approximately nine years later (M = 25.0 years), closeness to parents was assessed again as well as attachment style in their close relationships. Multilevel modeling was used to predict attachment style in young adulthood from the average and discrepancy of closeness to adolescents’ adoptive mothers and fathers and the change over time in closeness to APs. Less avoidant attachment style was predicted by stronger closeness to both APs during adolescence. Increased closeness to APs over time was related to less anxiety in close relationships. Higher closeness over time to either AP was related to less avoidance and anxiety in close relationships. PMID:25859067

Background Previous research has demonstrated that anxiety reliably predicts later depression, but little has been uncovered about the mechanism underlying this connection. Interpersonal relationships appear to be a viable mechanism of the association as anxiety has been shown to predict later deficits in both close (e.g., “best friendships”) and group relationships (e.g., classroom peer groups), and deficits in both close and group relationships have been linked to later depressive symptoms. The current study examined close and group relationships as potential mediators between anxiety and depression 12–14 years later. Methods In a nationally representative sample of adolescents (N = 6,504), anxiety was measured at baseline, perceptions of close relationships (i.e., feeling loved) and perceptions of group relationships (i.e., feeling part of a group) were measured 6 months later, and depression levels and diagnosis were measured 12–14 years later. Results Using structural equation models, the results showed that adolescent perceptions of both close and group relationships significantly mediated the relationship between adolescent anxiety and adult levels of depression. Furthermore, perceptions of not being accepted/loved in close relationships significantly mediated the relationship between adolescent anxiety and clinical depression in adulthood. Conclusions These results suggest that a perception of not being accepted in group relationships may be a mechanism by which heightened anxiety in adolescents leads to heightened nonclinical depression in adulthood. On the other hand, adolescent perceptions of not feeling loved or accepted in close relationships may be a mechanism by which heightened anxiety in adolescence leads to clinical depression—in adulthood.

Close relationship processes and health: implications of attachment theory for health and disease.

Pietromonaco, Paula R; Uchino, Bert; Dunkel Schetter, Christine

2013-05-01

Health psychology has contributed significantly to understanding the link between psychological factors and health and well-being, but it has not often incorporated advances in relationship science into hypothesis generation and study design. We present one example of a theoretical model, following from a major relationship theory (attachment theory) that integrates relationship constructs and processes with biopsychosocial processes and health outcomes. We briefly describe attachment theory and present a general framework linking it to dyadic relationship processes (relationship behaviors, mediators, and outcomes) and health processes (physiology, affective states, health behavior, and health outcomes). We discuss the utility of the model for research in several health domains (e.g., self-regulation of health behavior, pain, chronic disease) and its implications for interventions and future research. This framework revealed important gaps in knowledge about relationships and health. Future work in this area will benefit from taking into account individual differences in attachment, adopting a more explicit dyadic approach, examining more integrated models that test for mediating processes, and incorporating a broader range of relationship constructs that have implications for health. A theoretical framework for studying health that is based in relationship science can accelerate progress by generating new research directions designed to pinpoint the mechanisms through which close relationships promote or undermine health. Furthermore, this knowledge can be applied to develop more effective interventions to help individuals and their relationship partners with health-related challenges.

Enacting Firm, Fair and Friendly Practice: A Model for Strengths-Based Child Protection Relationships?

PubMed

Oliver, Carolyn; Charles, Grant

2016-06-01

Strengths-based solution-focused approaches are gaining ground in statutory child protection work, but few studies have asked front line practitioners how they navigate the complex worker-client relationships such approaches require. This paper describes one component of a mixed-methods study in a large Canadian statutory child protection agency in which 225 workers described how they applied the ideas of strengths-based practice in their daily work. Interviews with twenty-four practitioners were analysed using an interpretive description approach. Only four interviewees appeared to successfully enact a version of strengths-based practice that closely mirrored those described by key strengths-based child protection theorists and was fully congruent with their mandated role. They described navigating a shifting balance of collaboration and authority in worker-client relationships based on transparency, impartial judgement, attentiveness to the worker-client interaction and the value that clients were fellow human beings. Their accounts extend current conceptualisations of the worker-client relationship in strengths-based child protection work and are congruent with current understandings of effective mandated relationships. They provide what may be a useful model to help workers understand and navigate relationships in which they must reconcile their own authority and expertise with genuine support for the authority and expertise of their clients.

Social mobility and the well-being of individuals.

2018-03-01

Several papers published in recent years have revived interest in Sorokin's dissociative thesis: the view that intergenerational social mobility has detrimental effects on the social relationships and wellbeing of individuals. In this paper, I test the dissociative thesis using data from the British Household Panel Survey and Understanding Society. On a wide range of indicators that measure participation in civic associations, contact with parents, close personal relationships, social support, subjective wellbeing, etc. individuals who have achieved long-range upward mobility (i.e. those who move from working class origin to salariat destination) tend to fare better than those who are immobile in the working class. Those who have experienced long-range downward mobility (moving from salariat origin to working class destination) do about as well as second-generation members of the working class. Overall, there is no support for Sorokin's thesis. © London School of Economics and Political Science 2017.

A convenient and accurate wide-range parameter relationship between Buckingham and Morse potential energy functions

Lim, Teik-Cheng; Dawson, James Alexander

2018-05-01

This study explores the close-range, short-range and long-range relationships between the parameters of the Morse and Buckingham potential energy functions. The results show that the close-range and short-range relationships are valid for bond compression and for very small changes in bond length, respectively, while the long-range relationship is valid for bond stretching. A wide-range relationship is proposed to combine the comparative advantages of the close-range, short-range and long-range parameter relationships. The wide-range relationship is useful for replacing the close-range, short-range and long-range parameter relationships, thereby preventing the undesired effects of potential energy jumps resulting from functional switching between the close-range, short-range and long-range interaction energies.

Social anxiety and self-protective communication style in close relationships.

PubMed

Cuming, Samantha; Rapee, Ronald M

2010-02-01

People with higher social anxiety tend to reveal less information about themselves in interactions with strangers, and this appears to be part of a self-protective strategy adopted in situations in which the risk of negative evaluation is judged to be particularly high. This research examined whether a similar style of communication may be adopted by people with higher social anxiety in their close relationships, and whether it may be associated with decrements in the quality (support, depth, conflict) of these relationships. Over 300 people from the community completed a series of online questionnaires measuring social anxiety and depression, and disclosure in and quality of their close friendships and romantic relationships. After controlling for levels of depression, social anxiety was associated with a paucity of disclosure in both romantic relationships and close friendships in females, but not males. There was an indirect association between higher social anxiety and lower relationship quality (lower support, with a trend towards greater conflict) via lower self-disclosure in women's romantic relationships, but not their close friendships. Addressing disclosure in the context of close relationships may assist socially anxious women to develop more fulfilling and harmonious close relationships. Copyright 2009 Elsevier Ltd.

Emotional intelligence skills help nurses to cope with the emotional demands of healthcare environment. The aim of this study was to identify the relationship between emotional intelligence and perception of job performance among nurses. Using a correlational descriptive design with stratified random sampling, 338 registered nurses from teaching hospitals in North West of Iran were surveyed. Emotional intelligence and perception of job performance were measured using validated self-report measures. The collected data were analyzed through descriptive and inferential methods using SPSS/13. The mean of nurses' emotional intelligence and their perception of job performance was, respectively, 235.83 ± 37.98 and 157.63 ± 33.23. There was no significant relationship between nurses' emotional intelligence and their perception of job performance. Although there was a significant relationship between intrapersonal subscale of emotional intelligence and job performance, there was none with other subscales. In order to get rid of the physical and psychological effects of stressful work in wards, it seems that nurses just do routine activities and refuse working closely with the patients. It seems that fitting the patient to nurse ratio, dividing work between nurses, and supporting each other are necessary.

A Developmental Guide to the Organisation of Close Relationships

Laursen, Brett; Bukowski, William M.

2009-01-01

A developmental guide to close relationships is presented. Parent-child, sibling, friend, and romantic relationships are described along dimensions that address permanence, power, and gender. These dimensions describe relationship differences in organisational principles that encompass internal representations, social understanding, and interpersonal experiences. The concept of domain specificity is borrowed from cognitive development to address the shifting developmental dynamics of close relationships. Distinct relationships are organised around distinct socialisation tasks, so each relationship requires its own organisational system. As a consequence, different principles guide different relationships, and these organisational principles change with development. PMID:20090927

Teachers’ Relationship Closeness with Students as a Resource for Teacher Wellbeing: A Response Surface Analytical Approach

PubMed Central

Milatz, Anne; Lüftenegger, Marko; Schober, Barbara

2015-01-01

Teachers’ relationship quality with students has been argued to be an important source of teacher wellbeing. Thus, the current study aimed to investigate to what extent teachers’ relationship closeness toward students, combined with attachment security is a resource protecting against teacher burnout. Eighty-three elementary school teachers reported on their most and least attached student’s relationship closeness, their attachment security and levels of burnout, as measured by emotional exhaustion, depersonalization and personal accomplishment. Response surface analysis (RSA), enabling researchers to investigate the effect of congruence/incongruence of two predictors on an outcome, revealed that teachers’ depersonalization and emotional exhaustion were lowest when they developed homogenous close relationships toward the students within their classroom and when teachers in general made congruent relationship experiences. No RSA model could be specified for personal accomplishment, even though a correlational analysis revealed that increasing closeness with students fostered teachers’ personal accomplishment. Teachers’ secure attachment experiences were not directly related to burnout, but enhanced their capability to establish close relationships toward their students. Findings suggest that teachers’ relationships toward students are a resource for the teacher’s wellbeing, which highlights once again the importance of student–teacher relationships in education.

How do relationships support parenting? Effects of attachment style and social support on parenting behavior in an at-risk population.

PubMed

Green, Beth L; Furrer, Carrie; McAllister, Carol

2007-09-01

The importance of supportive relationships for new parents has been the focus of both research and parenting interventions. Attachment style, typically viewed as a relatively stable trait reflecting one's comfort in social relationships, as well as social support, or one's perception of the social context, have both been found to be important for fostering engaged, involved parenting. Less is known, however, about how these variables work together to influence parenting behavior, especially in families at higher risk for negative child outcomes. Data were collected from 152 urban, predominantly African American, low-income parents when their children were 14 and 36 months of age. Results suggest that parents with more social support show greater increases in the frequency of positive parent-child activities over time, but that this effect is mediated by mothers' attachment style, specifically, their level of anxious/ambivalent attachment. Mothers with more social support tended to be less anxious/ambivalent about close relationships, and this in turn led to increases over time in the frequency of parent-child interactions. Mothers' tendency to avoid close relationships, however, while correlated with social support, was unrelated to changes in parenting behavior. Implications of these findings for program development, parenting, and the malleability of attachment style based on social context are discussed.

Fostering Nurses' Moral Agency and Moral Identity: The Importance of Moral Community.

PubMed

Liaschenko, Joan; Peter, Elizabeth

2016-09-01

It may be the case that the most challenging moral problem of the twenty-first century will be the relationship between the individual moral agent and the practices and institutions in which the moral agent is embedded. In this paper, we continue the efforts that one of us, Joan Liaschenko, first called for in 1993, that of using feminist ethics as a lens for viewing the relationship between individual nurses as moral agents and the highly complex institutions in which they do the work of nursing. Feminist ethics, with its emphasis on the inextricable relationship between ethics and politics, provides a useful lens to understand the work of nurses in context. Using Margaret Urban Walker's and Hilde Lindemann's concepts of identity, relationships, values, and moral agency, we argue that health care institutions can be moral communities and profoundly affect the work and identity and, therefore, the moral agency of all who work within those structures, including nurses. Nurses are not only shaped by these organizations but also have the power to shape them. Because moral agency is intimately connected to one's identity, moral identity work is essential for nurses to exercise their moral agency and to foster moral community in health care organizations. We first provide a brief history of nursing's morally problematic relationship with institutions and examine the impact institutional master narratives and corporatism exert today on nurses' moral identities and agency. We close by emphasizing the significance of ongoing dialogue in creating and sustaining moral communities, repairing moral identities, and strengthening moral agency. © 2016 The Hastings Center.

Healthcare quality improvement work: a professional employee perspective.

PubMed

Gadolin, Christian; Andersson, Thomas

2017-06-12

Purpose The purpose of this paper is to describe and analyze conditions that influence how employees engage in healthcare quality improvement (QI) work. Design/methodology/approach Qualitative case study based on interviews ( n=27) and observations ( n=10). Findings The main conditions that influence how employees engage in healthcare QI work are professions, work structures and working relationships. These conditions can both prevent and facilitate healthcare QI. Professions and work structures may cement existing institutional logics and thus prevent employees from engaging in healthcare QI work. However, attempts to align QI with professional logics, together with work structures that empower employees, can make these conditions increase employee engagement, which can be accomplished through positive working relationships that foster institutional work, which bridge different competing institutional logics, making it possible to overcome barriers that professions and work structures may constitute. Practical implications Understanding the conditions that influence how employees engage in healthcare QI work will make initiatives more likely to succeed. Originality/value Healthcare QI has mainly been studied from an implementer perspective, and employees have either been neglected or seen as passive resisters. Weak employee perspectives make healthcare QI research incomplete. In our research, healthcare QI work is studied closely at the actor level to understand healthcare QI from an employee perspective.

The relationships between starch structure and functionality are important in underpinning the industrial and nutritional utilisation of starches. In this work, the relationships between the biosynthesis, structure, molecular organisation and functionality have been examined using a series of defined genotypes in barley with low (<20%), standard (20-30%), elevated (30-50%) and high (>50%) amylose starches. A range of techniques have been employed to determine starch physical features, higher order structure and functionality. The two genetic mechanisms for generating high amylose contents (down-regulation of branching enzymes and starch synthases, respectively) yielded starches with very different amylopectin structures but similar gelatinisation and viscosity properties driven by reduced granular order and increased amylose content. Principal components analysis (PCA) was used to elucidate the relationships between genotypes and starch molecular structure and functionality. Parameters associated with granule order (PC1) accounted for a large percentage of the variance (57%) and were closely related to amylose content. Parameters associated with amylopectin fine structure accounted for 18% of the variance but were less closely aligned to functionality parameters. Copyright © 2012 Elsevier Ltd. All rights reserved.

Emotional closeness to parents and grandparents: A moderated mediation model predicting adolescent adjustment.

Attar-Schwartz, Shalhevet

2015-09-01

Warm and emotionally close relationships with parents and grandparents have been found in previous studies to be linked with better adolescent adjustment. The present study, informed by Family Systems Theory and Intergenerational Solidarity Theory, uses a moderated mediation model analyzing the contribution of the dynamics of these intergenerational relationships to adolescent adjustment. Specifically, it examines the mediating role of emotional closeness to the closest grandparent in the relationship between emotional closeness to a parent (the offspring of the closest grandparent) and adolescent adjustment difficulties. The model also examines the moderating role of emotional closeness to parents in the relationship between emotional closeness to grandparents and adjustment difficulties. The study was based on a sample of 1,405 Jewish Israeli secondary school students (ages 12-18) who completed a structured questionnaire. It was found that emotional closeness to the closest grandparent was more strongly associated with reduced adjustment difficulties among adolescents with higher levels of emotional closeness to their parents. In addition, adolescent adjustment and emotional closeness to parents was partially mediated by emotional closeness to grandparents. Examining the family conditions under which adolescents' relationships with grandparents is stronger and more beneficial for them can help elucidate variations in grandparent-grandchild ties and expand our understanding of the mechanisms that shape child outcomes.

Analyses of the pattern of associations, social interactions, coalitions, and aggression among chacma baboons (Papio hamadryas ursinus) in the Okavango Delta of Botswana over a 16-year period indicate that adult females form close, equitable, supportive, and enduring social relationships. They show strong and stable preferences for close kin, particularly their own mothers and daughters. Females also form strong attachments to unrelated females who are close to their own age and who are likely to be paternal half-sisters. Although absolute rates of aggression among kin are as high as rates of aggression among nonkin, females are more tolerant of close relatives than they are of others with whom they have comparable amounts of contact. These findings complement previous work which indicates that the strength of social bonds enhances the fitness of females in this population and support findings about the structure and function of social bonds in other primate groups.

Our recent work showed that close relationships result in shared cognitive and neural representations of the self and one’s mother in collectivistic individuals (Zhu et al., 2007, Neuroimage, 34, 1310–7). However, it remains unknown whether close others, such as mother, father and best friend, are differentially represented in collectivistic brains. Here, using functional magnetic resonance imaging and a trait judgment task, we showed evidence that, while trait judgments of the self and mother generated comparable activity in the medial prefrontal cortex (MPFC) and anterior cingulate (ACC) of Chinese adults, trait judgments of mother induced greater MPFC/ACC activity than trait judgments of father and best friend. Our results suggest that, while neural representations of the self and mother overlapped in the MPFC/ACC, close others such as mother, father and best friend are unequally represented in the MPFC/ACC of collectivistic brains.

To explore the relationship between nurses and caregivers using a web camera and web forum as the communication methods. In Norway and other European countries, there is an increased focus on ageing at home, which is aided by technology, as well as formal and informal care. The literature reveals that caregivers endure physical and mental burdens. With computer-mediated communication, such as telecare, it is possible for nurses to provide supportive care to caregivers in their homes. An explorative design using qualitative content analysis. Six nurses and nine caregivers with residential spouses suffering from stroke or dementia were interviewed two times over a six-month period. The nurses responded dynamically to the information they received and helped to empower the individual caregivers and to strengthen the interpersonal relationships between the caregivers. While some participants thought that meeting in a virtual room was close and intimate, others wanted to maintain a certain distance. The participants' altered their roles as the masters and receivers of knowledge and experience; this variation was based on a relationship in which mutual respect for one another and an interest in learning from one another allowed them to work together as partners to demonstrate the system and to follow-up with new caregivers. The flexibility of the service allows the possibility of engaging in a close, or to some extent, a more distant relationship, depending on the participants' attitudes towards using this type of service. Nurses can provide close care, support and information to caregivers who endeavour to master their everyday lives together with their sick spouses. The support seems to help the caregivers cope with their own physical and emotional problems. © 2015 The Authors. Journal of Clinical Nursing published by John Wiley & Sons Ltd.

Minding the close relationship.

PubMed

Harvey, J H; Omarzu, J

1997-01-01

In this theoretical analysis, we argue that a process referred to as minding is essential for a couple to feel mutually close and satisfied in a close relationship over a long period Minding represents a package of mutual self-disclosure, other forms of goal-oriented behavior aimed at facilitating the relationship, and attributions about self's and other's motivations, intentions, and Mort in the relationship. Self-disclosure and attribution activities in minding are aimed at getting to know the other, trying to understand the other's motivations and deeper disposition as they pertain to the relationship, and showing respect and acceptance for knowledge gained about other. We link the concept of minding to other major ideas and literatures about how couples achieve closeness: self-disclosure and social penetration, intimacy, empathy and empathic accuracy, and love and self-expansion. We argue that the minding process articulated here has not previously been delineated and that it is a useful composite notion about essential steps in bonding among humans. We also argue that the minding concept stretches our understanding of the interface of attribution and close relationships. We present research possibilities and implications and consider possible alternative positions and counter arguments about the merits of the minding idea for close relationship satisfaction.

The extent to which social relationships influence cognitive aging is unclear. In this study, we investigated the association of midlife quality of close relationships with subsequent cognitive decline. Participants in the Whitehall II Study (n = 5,873; ages 45–69 years at first cognitive assessment) underwent executive function and memory tests 3 times over a period of 10 years (1997–1999 to 2007–2009). Midlife negative and positive aspects of close relationships were assessed twice using the Close Persons Questionnaire during the 8 years preceding cognitive assessment. Negative aspects of close relationships, but not positive aspects, were associated with accelerated cognitive aging. Participants in the top third of reported negative aspects of close relationships experienced a faster 10-year change in executive function (−0.04 standard deviation, 95% confidence interval: −0.08, −0.01) than those in the bottom third, which was comparable with 1 extra year of cognitive decline for participants aged 60 years after adjustment for sociodemographic and health status. Longitudinal analysis found no evidence of reverse causality. This study highlights the importance of differentiating aspects of social relationships to evaluate their unique associations with cognitive aging. PMID:25342204

This study analyzes the relationship between gender and self-perceived health status in Spanish retirees and housewives from a sample of 1,106 community-dwelling older adults. A multivariate linear regression model was used in which self-perceived health status was measured by the EQ-5D visual analogue scale and gender according to work status (retired men and women and housewives). Retired males reported a significantly better health status than housewives. Self-perceived health status was closely associated with physical, mental, and functional health and leisure activities. Finally, being a woman with complete dedication to domestic work is associated with a worse state of self-perceived health.

The purpose of this mixed methods study was to examine the quality of work life of registered nurses working in obstetrics at 4 hospitals in northeastern Ontario and explore demographic and occupational factors related to nurses' quality of work life (QWL). A stratified random sample of registered nurses (N = 111) selected from the 138 eligible registered nurses (80.4%) of staff in the labor, delivery, recovery, and postpartum areas at the 4 hospitals participated. Logistic regression analyses were used to consider QWL in relation to the following: 1) demographic factors, and 2) stress, employment status and educational attainment. In the logistic regression model, the odds of a higher quality of work life for nurses who were cross trained (nurses who can work across all areas of obstetrical care) were estimated to be 3.82 (odds ratio = 3.82, 95% confidence interval: 1.01-14.5) times the odds of a higher quality of work life for nurses who were not cross trained. This study highlights a relationship between quality of work life and associated factors including location of cross-training among obstetrical nurses in northeastern Ontario. These findings are supported by the qualitative interviews that examine in depth their relationship to QWL. Given the limited number of employment opportunities in the rural and remote regions, it is paramount that employers and employees work closely together in creating positive environments that promote nurses' QWL.

Signaling When (and When Not) to Be Cautious and Self-Protective: Impulsive and Reflective Trust in Close Relationships

2011-01-01

A dual process model is proposed to explain how automatic evaluative associations to the partner (i.e., impulsive trust) and deliberative expectations of partner caring (i.e., reflective trust) interact to govern self-protection in romantic relationships. Experimental and correlational studies of dating and marital relationships supported the model. Subliminally conditioning more positive evaluative associations to the partner increased confidence in the partner’s caring, suggesting that trust has an impulsive basis. Being high on impulsive trust (i.e., more positive evaluative associations to the partner on the IAT) also reduced the automatic inclination to distance in response to doubts about the partner’s trustworthiness. It similarly reduced self-protective behavioral reactions to these reflective trust concerns. The studies further revealed that the effects of impulsive trust depend on working memory capacity: Being high on impulsive trust inoculated against reflective trust concerns for people low on working memory capacity.

Koomen, Helma M Y; Jellesma, Francine C

The constructs of closeness, conflict, and dependency, which are derived from attachment theory, are widely used to qualify teachers' perceptions of relationships with individual children. Our main aim was to reveal whether similar and reliable dimensions could be identified in middle childhood with a newly developed student measure Student Perception of Affective Relationship with Teacher Scale (SPARTS). Additional validity support was sought by examining gender differences and associations with (1) teacher relationship perceptions and (2) problem and prosocial behaviours in children. Factor structure was determined in a sample of 586 children (46.5% boys) from 26 regular elementary Dutch classrooms (grade 4-6). Associations with teacher relationship reports (n = 82) and child behaviours (n = 64) were analysed in random subsamples. Students' relationship perceptions were assessed with the SPARTS; teachers' relationship perceptions with the Student-Teacher Relationship Scale (STRS; closeness, conflict, and dependency); and problem and prosocial behaviours in children with the teacher-reported Strengths and Difficulties Questionnaire. Exploratory factor analysis and confirmatory factor analysis supported a 3-factor model of conflict, closeness, and a third factor, unexpectedly reflecting negative expectations of the student instead of dependency. Satisfactory internal consistency was found for all three scales. Additional validity evidence included the following: Substantial student-teacher agreement for conflict and closeness; meaningful associations with problem and prosocial behaviours in children; and expected gender differences showing that, compared to boys, girls share more favourable relationships (more closeness and less conflict) with teachers. The 3-dimensional SPARTS comes close to the attachment-derived teacher STRS, as far as conflict and closeness are concerned. The third dimension, negative expectations, represents a new and relevant attachment-related dimension reflecting a lack of confidence of students in the relationship with their teacher. © 2015 The British Psychological Society.

The Close Relationships of People with Intellectual Disabilities: A Qualitative Study.

2016-03-01

Positive interpersonal relationships have been found to enhance an individual's quality of life. However, people with intellectual disabilities (PWID) often have restricted social networks, and little is known about their views on close social relationships. The study aimed to explore how this group perceives and experiences close relationships. Ten (6 = men 4 = women) PWID participated. Data were collected using semi-structured interviews, and analysed using interpretive phenomenological analysis. The results report on three of five themes drawn from a larger qualitative study: 'Relationships feeling safe and being useful'; 'Who's in charge?' and 'Struggling for an ordinary life'. Close relationships are valued and desired by PWID, but a variety of barriers inhibit their development and maintenance. This includes the failure of others to value, accept and appropriately support the independence and relationships of PWID. Potential ways of addressing these issues are discussed. © 2015 John Wiley & Sons Ltd.

Measuring the Closeness of Relationships: A Comprehensive Evaluation of the 'Inclusion of the Other in the Self' Scale

PubMed Central

2015-01-01

Understanding the nature and influence of social relationships is of increasing interest to behavioral economists, and behavioral scientists more generally. In turn, this creates a need for tractable, and reliable, tools for measuring fundamental aspects of social relationships. We provide a comprehensive evaluation of the 'Inclusion of the Other in the Self' (IOS) Scale, a handy pictorial tool for measuring the subjectively perceived closeness of a relationship. The tool is highly portable, very easy for subjects to understand and takes less than 1 minute to administer. Across our three online studies with a diverse adult population (n = 772) we show that six different scales designed to measure relationship closeness are all highly significantly positively correlated with the IOS Scale. We then conduct a Principal Component Analysis to construct an Index of Relationship Closeness and find that it correlates very strongly (ρ = 85) with the IOS Scale. We conclude that the IOS Scale is a psychologically meaningful and highly reliable measure of the subjective closeness of relationships. PMID:26068873

Individuals increasingly connect with others via social media (e.g., blogs, social networking, chatrooms), a phenomenon that is likely to impact psychological well-being and development. As such, therapists play an important role in assisting their clients to identify how virtual and in-person relationships influence their sense of self, interpersonal communication, and how they engage in meaningful relationships. In this article, I describe 3 examples related to working with emerging adults that take into consideration how this population "does relationships" in this technological era. Specifically, 3 clinical exchanges illustrate ways to (a) enhance interpersonal skills, (b) develop self-awareness about emotions, and (c) gain a clearer understanding of the intersections of social identity.

Solar variability investigations that include magnetic energy coupling are paramount to solving many key solar/stellar physics problems, particularly for understanding the temporal variability of magnetic energy redistribution and heating processes. Using three years of observations from the Solar Dynamics Observatory ’ s Atmospheric Imaging Assembly and Heliosemic Magnetic Imager, we measured radiative and magnetic fluxes from gross features and at full-disk scales, respectively. Magnetic energy coupling analyses support radiative flux descriptions via the plasma heating connectivity of dominant (magnetic) and diffuse components, specifically of the predominantly closed-field corona. Our work shows that this relationship favors an energetic redistribution efficiency acrossmore » large temperature gradients, and potentially sheds light on the long-standing issue of diffuse unresolved low corona emission. The close connection between magnetic energy redistribution and plasma conditions revealed by this work lends significant insight into the field of stellar physics, as we have provided possible means for probing distant sources in currently limited and/or undetectable radiation distributions.« less

The purpose of this work is to examine the gross visceral anatomy of ocean sunfish and angler using non-invasive imaging techniques: computed tomography imaging (CT) and magnetic resonance imaging (MRI). Similarities and differences in the internal organisation of these two species are verified. Both species lack a swimbladder and present a significant asymmetry in the hepatic lobes, an elongated bile duct terminating close to the stomach, a compact thyroid embedded in a blood lacuna, and very reduced brain and spinal cord. These observations are important in regard to the close relationships between Tetraodontiformes and Lophiiformes, established by several molecular works, but not yet confirmed by morpho-anatomical data. However the occurrence of these features has to be examined in other taxa before phylogenetic hypotheses are proposed. Copyright © 2012 Académie des sciences. Published by Elsevier SAS.

Conservation and laundry: using outside vendors to clean reusable linens.

PubMed

McKnight, D

1992-08-01

Using outside laundry facilities is a viable and efficient means for hospitals to clean and sanitize soiled linens. Such services also allow hospitals to achieve cost-effective linen systems. All kinds of linen products, including gowns, sheets, blankets, pillowcases, mops, diapers, and surgical textiles, are easily processed through such purveyors. Even newer fabrics with improved barrier protection qualities can be serviced. The three elements that make up the laundry cost equation are purchasing, processing, and usage. Improvements and reductions in any one of these areas positively affect the other two. With this in mind, a hospital and an outside laundry service should work closely together to improve linen management, to control usage, and to remove waste, thus reducing hospitals' per-patient-day costs. Close interaction and teamwork will make the relationship work with dynamic results. Together, both parties will grow and meet the ever-evolving needs of the health care industry.

Subjective well-being as a predictor for later behavior and health has highlighted its relationship to health, work performance, and social relationships. However, the majority of such studies neglect the developmental nature of well-being in contributing to important changes across the transition to adulthood. To examine the potential role of subjective well-being as a long-term predictor of critical life outcomes, we examined indicators of positive and negative affect at age 14 as predictors of relationship, adjustment, self-worth, and career outcomes a decade later at ages 23 to 25, controlling for family income and gender. We utilised multi-informant methods including reports from the target participant, close friends, and romantic partners in a demographically diverse community sample of 184 participants. Early adolescent positive affect predicted fewer relationship problems (less self-reported and partner-reported conflict, and greater friendship attachment as rated by close peers) and healthy adjustment to adulthood (lower levels of depression, anxiety, and loneliness). It also predicted positive work functioning (higher levels of career satisfaction and job competence) and increased self-worth. Negative affect did not significantly predict any of these important life outcomes. In addition to predicting desirable mean levels of later outcomes, early positive affect predicted beneficial changes across time in many outcomes. The findings extend early research on the beneficial outcomes of subjective well-being by having an earlier assessment of well-being, including informant reports in measuring a large variety of outcome variables, and by extending the findings to a lower socioeconomic group of a diverse and younger sample. The results highlight the importance of considering positive affect as an important component of subjective well-being distinct from negative affect. © 2016 The International Association of Applied Psychology.

Epistemic companions: shared reality development in close relationships.

PubMed

Rossignac-Milon, Maya; Higgins, E Tory

2018-01-11

We propose a framework outlining the development of shared reality in close relationships. In this framework, we attempt to integrate disparate close relationship phenomena under the conceptual umbrella of shared reality. We argue that jointly satisfying epistemic needs-making sense of the world together-plays an important but under-appreciated role in establishing and maintaining close relationships. Specifically, we propose that dyads progress through four cumulative phases in which new forms of shared reality emerge. Relationships are often initiated when people discover Shared Feelings, which then facilitate the co-construction of dyad-specific Shared Practices. Partners then form an interdependent web of Shared Coordination and ultimately develop a Shared Identity. Each emergent form of shared reality continues to evolve throughout subsequent phases, and, if neglected, can engender relationship dissolution. Copyright © 2018 Elsevier Ltd. All rights reserved.

We used data from a US national sample of Internet users, ages 10-17 (N=1501), to explore the characteristics of youth who had formed close relationships with people they met on the Internet (n=210). Girls who had high levels of conflict with parents or were highly troubled were more likely than other girls to have close online relationships, as were boys who had low levels of communication with parents or were highly troubled, compared to other boys. Age, race and aspects of Internet use were also related. We know little about the nature or quality of the close online relationships, but youth with these sorts of problems may be more vulnerable to online exploitation and to other possible ill effects of online relationships. At the same time, these relationships may have helpful aspects.

The Conditions under which Growth-Fostering Relationships Promote Resilience and Alleviate Psychological Distress among Sexual Minorities: Applications of Relational Cultural Theory

Mereish, Ethan H.; Poteat, V. Paul

2015-01-01

Relational cultural theory posits that resilience and psychological growth are rooted in relational connections and are facilitated through growth-fostering relationships. Framed within this theory, the current study examined the associations between growth-fostering relationships (i.e., relationships characterized by authenticity and mutuality) with a close friend and psychological distress among sexual minorities. More specifically, we tested the moderating effects of individuals’ internalized homophobia and their friend’s sexual orientation on the associations between growth-fostering relationship with their close friend and level of psychological distress. A sample of sexual minorities (N = 661) were recruited online and completed a questionnaire. The 3-way interaction between (a) growth-fostering relationship with a close friend, (b) the close friend’s sexual orientation, and (c) internalized homophobia was significant in predicting psychological distress. Among participants with low levels of internalized homophobia, a stronger growth-fostering relationship with a close heterosexual or LGBT friend was associated with less psychological distress. Among participants with high levels of internalized homophobia, a stronger growth-fostering relationship with a close LGBT friend was associated with less psychological distress but not with a heterosexual friend. Our results demonstrate that growth-fostering relationships may be associated with less psychological distress but under specific conditions. These findings illuminate a potential mechanism for sexual minorities’ resilience and provide support for relational cultural theory. Understanding resilience factors among sexual minorities is critical for culturally sensitive and affirmative clinical practice and future research. PMID:26380836

This paper reports a study aiming to present and describe the effects of whistleblowing episodes on nurses' workplace relationships. Eighteen participants with direct experience of whistleblowing were recruited into the study, which was informed by a qualitative narrative inquiry design. Findings were clustered into four main themes, namely: Leaving and returning to work-The staff don't like you; Spoiled collegial relationships-Barriers between me and my colleagues; Bullying and excluding-They've just closed ranks; and, Damaged inter-professional relationships-I did lose trust in doctors after that. Findings suggest a need to facilitate a climate in which it is safe for nurses (and others) to raise concerns about patient care or organisational wrongdoing, and to eliminate the existing belief that whistleblowing is a negative act fuelled by revenge or sedition.

Being a close relative brings with it a large number of consequences, with the life situation changing over time. The aim of this study was to illuminate the experiences of being a middle-aged close relative of a person who has suffered a stroke 6 months after being discharged from a medical rehabilitation clinic. Narrative interviews were conducted with nine middle-aged close relatives and analysed using a content analysis with a latent approach. The analysis revealed that being close to someone who had suffered a stroke 6 months after discharge meant; a struggling for control and a renewal of family life in the shadow of suffering and hope. The middle-aged close relatives began to perceive the changed reality. They were struggling to take on something new, become reconciled and find a balance in their family life. Their ability to work, relief from caring concerns and having support and togetherness with others seemed to be essential for the close relatives in their efforts to manage their life situation and maintain their well-being. Having reached the 'halfway point' in their lives and still with half of their life in front of them created worries. They felt dejected about their changed relationships and roles, experience a sense of loss of shared child responsibilities, a negative impact on their marital relationships and sexual satisfaction. They felt trapped in a caring role and they worried about how to endure in the future. The middle-aged close relatives' experiences were of being alone and neglected, in an arduous and complex life situation filled with loss and grief. The findings highlights that health professionals need to see and listen to the close relatives' experiences of transition in order to provide appropriate support adjusted to their varying needs during a time of renewal.

Lower status jobs, high workloads and lack of control at work have been associated with less healthful diets, but the ways through which work is connected to food choices are not well understood. This analysis was an examination of workers' experience of the relationship of their jobs to their food choices. Fifty-one multi-ethnic, urban, low- and moderate-income adults living in Upstate New York in 1995 participated in a qualitative interview study of fruit and vegetable choices and discussed employment and food choices. The workers who participated in this study described a dynamic relationship between work and food choices that they experienced in the context of their other roles and values. These workers presented a relationship that was characterized by positive and negative spillover between their jobs and their ability to fulfill family roles and promote personal health, linked by a spectrum of food choice strategies. Participants' narratives fit into three different domains: characterizations of work and their resources for food choice, strategies used to manage food choices within the constraints of work, and affect related to the negative and positive spillover of these strategies on family roles and on personal food choices. Characterizations of work as demanding and limiting or demanding and manageable differentiated participants who experienced their food choice strategies as a source of guilt and dissatisfaction (negative spillover) from those who experienced food choices as a source of pride and satisfaction (positive spillover). Ideals and values related to food choice and health were balanced against other values for family closeness and nurturing and personal achievement. Some participants found work unproblematic. These findings direct attention to a broad conceptualization of the relationship of work to food choices in which the demands and resources of the work role are viewed as they spill over into the social and temporal context of other roles and values.

Relationship between concealment of emotions at work and musculoskeletal symptoms: results from the third Korean Working Conditions Survey.

In this study, we explored the relationship between concealing emotions at work and musculoskeletal symptoms in Korean workers using data from a national, population-based survey. Data were obtained from the third Korean Working Conditions Survey in 2011. We investigated the prevalence of three musculoskeletal symptoms ("back pain", "pain in the upper extremities", and "pain in the lower extremities"). Multiple logistic regression analysis was also performed to determine odds ratios (ORs) for musculoskeletal symptoms according to concealing emotions at work, adjusting for socioeconomic factors. In both sexes, the emotion-concealing group showed a significantly higher prevalence of "pain in the upper extremities" and "pain in the lower extremities" than the non-emotion-concealing group. For back pain, male - but not female - workers who concealed their emotions showed a higher prevalence than their non-emotion-concealing counterparts; the difference was statistically significant. Adjusted ORs for musculoskeletal symptoms (excluding "back pain" for female workers) in the emotion-concealing group were significantly higher. Our study suggests that concealment of emotions is closely associated with musculoskeletal symptoms, and the work environment should operate in consideration not only of the physical health work condition of workers but also of their emotional efforts including concealing emotion at work.

Understanding the working relationships between National Health Service clinicians and finance staff.

Minogue, Virginia; McCaffry, Rebecca

2017-03-13

Purpose The Department of Health and the National Health Service (NHS) Future Focused Finance (FFF) programme promotes effective engagement between clinical and finance staff. Surveys undertaken by the Department of Health between 2013 and 2015 found few NHS Trusts reported high levels of engagement. The purpose of this paper is to gain a better understanding of current working relationships between NHS clinical and finance professionals and how they might be supported to become more effective. Design/methodology/approach Ipsos MORI were commissioned by the NHS FFF programme to undertake an online survey of NHS clinical and finance staff between June and August 2015. Findings The majority of clinicians had a member of a finance team linked to their speciality or directorate. Clinical and finance professionals have a positive view of joint working preferring face-to-face contact. Clinician's confidence in their understanding of finance was generally good and finance staff felt they had a good understanding of clinical issues. Effective working relationships were facilitated by face-to-face contact, a professional relationship, and the availability of clear, well presented finance and activity data. Research limitations/implications Data protection issues limited the accessibility of the survey team to NHS staff resulting in a relatively low-response rate. Other forms of communication, including social media, were utilised to increase access to the survey. Originality/value The FFF programme is a unique programme aimed at making the NHS finance profession fit for the future. The close partnering work stream brings together the finance and clinical perspective to share knowledge, evidence, training, and to develop good practice and engagement.

Behavior Problems in Elementary School among Low-Income Males: The Role of Teacher-Child Relationships

PubMed Central

O’Connor, Erin Eileen; Supplee, Lauren

2017-01-01

The present study identified trajectories of teacher-child relationship conflict and closeness from first through sixth grades, and associations between these trajectories and externalizing and internalizing behaviors at age 11 among low-income, urban males (N = 262). There were three main findings. Nagin cluster analyses indicated five trajectories for conflict with all children evidencing increases in conflict, and four trajectories for closeness with all children demonstrating decreases in closeness. Trajectories with higher levels of conflict and lower levels of closeness were associated with higher levels of externalizing and internalizing behavior problems at age 11. Moreover, conflictual teacher-child relationships exacerbated the effects of externalizing and internalizing behavior problems in early childhood; children with conflictual teacher-child relationships had higher levels of behavior problems in middle childhood relative to children with low conflictual teacher-child relationships. Implications of targeting teacher-child relationships as interventions to help prevent behavior problems are discussed. PMID:29170565

The prosocial versus proself power holder: how power influences sacrifice in romantic relationships.

Romantic partners often have to sacrifice their interests to benefit their partner or to maintain the relationship. In the present work, we investigated whether relative power within the relationship plays an important role in determining the extent to which partners are likely to sacrifice. Drawing from both classic theories and recent research on power, we tested two competing predictions on the relationship between power and sacrifice in romantic relationships. We tested whether (a) power is negatively related to sacrifice and (b) power is positively related to sacrifice. Furthermore, we also explored whether the association between power and sacrifice is moderated by commitment and inclusion of the other in the self. To test our hypotheses, we used different methodologies, including questionnaires, diary studies, and videotaped interactions. Results across the five studies (N = 1,088) consistently supported the hypothesis that power is negatively related to tendencies to sacrifice in close relationships. © 2015 by the Society for Personality and Social Psychology, Inc.

Social anxiety and romantic relationships: the costs and benefits of negative emotion expression are context-dependent.

Kashdan, Todd B; Volkmann, Jeffrey R; Breen, William E; Han, Susan

2007-01-01

In general, expressing emotions is beneficial and withholding emotions has personal and social costs. Yet, to serve social functions there are situations when emotions are withheld strategically. We examined whether social anxiety influenced when and how emotion expressiveness influences interpersonal closeness in existing romantic relationships. For people with greater social anxiety, withholding the expression of negative emotions was proposed to preserve romantic relationships and their benefits. We examined whether social anxiety and emotion expressiveness interacted to predict prospective changes in romantic relationship closeness over a 12-week period. For people with less social anxiety, relationship closeness was enhanced over time when negative emotions were openly expressed whereas relationship deterioration was found for those more likely to withhold emotions. The reverse pattern was found for people with greater social anxiety such that relationship closeness was enhanced over time for those more likely to withhold negative emotions. Related social anxiety findings were found for discrepancies between desired and actual feelings of closeness over time. Findings were not attributable to depressive symptoms. These results suggest that the costs and benefits of emotion expression are influenced by a person's degree of social anxiety.

Work, love, and death-thought accessibility: A terror management investigation.

PubMed

McCabe, Simon; Daly, Michael

2018-05-07

Terror management theory suggests that following culturally derived scripts for valued behaviour protects people from death concerns, and conversely, not meeting standards for cultural value can weaken this protection, heightening mortality concerns. Using this conceptual framework, we examine (1) how considerations of loss of employment, a source of cultural value for many, relates to the accessibility of death-related cognition, and (2) the moderating role of job market health, and (3) involvement in close relationships. Study 1 found that writing about being unemployed (vs. a control topic) led to greater mortality-related cognition. Study 2 found that considering unemployment heightened death cognition, but only when participants were led to perceive the job market as unhealthy. Finally, Study 3 found that considering unemployment led to greater death cognition, but not for those involved in a close relationship. Findings offer insight into a previously overlooked consequence of unemployment, and factors that may serve a protective function. © 2018 The British Psychological Society.

Adolescent Perceptions of Conflict in Interdependent and Disengaged Friendships

Shulman, Shmuel; Laursen, Brett

2009-01-01

Interdependent and disengaged friendships in a middle-class sample of suburban Israeli adolescents were examined for differences in reports of conflict behavior. A total of 194 (100 females, and 94 males) close, reciprocal friends participated in a joint problem-solving task used to categorize friendships. Interdependent friends balanced closeness and individuality by cooperating on the task, whereas disengaged friends emphasized individuality by working independently on the task. In separate interviews, these friends recounted their most important conflict from the previous week. Older adolescents (M = 17.4 years) reported more conflicts over private disrespect than did younger adolescents (M = 12.7 years), whereas younger adolescents reported more conflicts over public disrespect and undependability than did older adolescents. Differences between friendship types in conflict initiation, negative affect, and relationship impact were found among older adolescents but not younger adolescents; differences in conflict resolutions were found in both age groups. In contrast to disengaged friends, interdependent friends were better able to manage conflicts in a manner that emphasized relationship harmony over individual gain. PMID:20090925

Simple radiative transfer model for relationships between canopy biomass and reflectance

Park, J. K.; Deering, D. W.

1982-01-01

A modified Kubelka-Munk model has been utilized to derive useful equations for the analysis of apparent canopy reflectance. Based on the solution to the model simple working equations were formulated by employing reflectance characteristic parameters. The relationships derived show the asymptotic nature of reflectance data that is typically observed in remote sensing studies of plant biomass. They also establish the range of expected apparent canopy reflectance values for specific plant canopy types. The usefulness of the simplified equations was demonstrated by the exceptionally close fit of the theoretical curves to two separately acquired data sets for alfalfa and shortgrass prairie canopies.

Close relationships and attributions for peer victimization among late adolescents.

PubMed

Chen, Xiaochen; Graham, Sandra

2012-12-01

This study examined the effect of close relationships (best friendship and romantic relationship) on late adolescents' casual attributions for peer victimization. A total of 1106 twelfth grade students completed self-report measures of perceived peer victimization, self-blame attribution, psychological maladjustment (loneliness and social anxiety), and quality of close peer relationships. Results indicated that self-blame partly mediated the link between peer victimization and psychological maladjustment. Relationship quality moderated the victimization-self-blame relation. Participants were more likely to endorse self-blame attributions for peer victimization when they had a negative relationship with a best friend or romantic partner. The moderated effect of negative best friendship quality was only significant for girls, whereas the moderated effect of negative romantic relationship quality was only significant for boys. Implications of these findings for future research on close relations during adolescence and for interventions to reduce the effects of peer victimization were discussed.

What determines forgiveness in close relationships? The role of post-transgression trust.

PubMed

Strelan, Peter; Karremans, Johan C; Krieg, Josiah

2017-03-01

Relationship closeness is one of the best predictors of forgiveness. But what is the process by which closeness encourages forgiveness? Across three studies, we employed a mix of experimental and correlational designs with prospective (N = 108), scenario (N = 71), and recall (N = 184) paradigms to test a multiple mediation model. We found consistent evidence that the positive association between relationship closeness and forgiveness may be explained by levels of post-transgression trust in the offender. Moreover, trust always played the main mediating role in the forgiveness process, even when taking into account several transgression-specific variables associated with both trust and forgiveness (e.g., apology). We discuss the theoretical and practical implications of trust as a key indicator of forgiveness in close relationships. © 2016 The British Psychological Society.

Depression, anxiety and quality of life in suicide survivors: a comparison of close and distant relationships.

2009-02-01

The study's purpose was to describe and compare depression, anxiety, and quality of life, by degree of relationship, between closely related and distantly related survivors (persons close to the suicide victim, or "suicide survivors"; N = 60) during the acute phase of bereavement (within 1 month of the death). The close relationship category included spouses, parents, children, and siblings, whereas the distant relationship category included in-laws, aunts/uncles, and nieces/nephews. Analysis of covariance examined differences between the two groups on the symptom measures. Results indicate that, after controlling for age and gender effects, closely related survivors had significantly higher mean levels of depression and anxiety and had lower levels of mental health quality of life. There were no statistically significant differences on the physical health quality of life subscale.

The dynamics of close relationships is important for understanding the migration patterns of individual life-courses. The bottom-up approach to this subject by social scientists has been limited by sample size, while the more recent top-down approach using large-scale datasets suffers from a lack of detail about the human individuals. We incorporate the geographic and demographic information of millions of mobile phone users with their communication patterns to study the dynamics of close relationships and its effect in their life-course migration. We demonstrate how the close age- and sex-biased dyadic relationships are correlated with the geographic proximity of the pair of individuals, e.g., young couples tend to live further from each other than old couples. In addition, we find that emotionally closer pairs are living geographically closer to each other. These findings imply that the life-course framework is crucial for understanding the complex dynamics of close relationships and their effect on the migration patterns of human individuals.

When Work is Related to Disease, What Establishes Evidence for a Causal Relation?

Verbeek, Jos

2012-06-01

Establishing a causal relationship between factors at work and disease is difficult for occupational physicians and researchers. This paper seeks to provide arguments for the judgement of evidence of causality in observational studies that relate work factors to disease. I derived criteria for the judgement of evidence of causality from the following sources: the criteria list of Hill, the approach by Rothman, the methods used by International Agency for Research on Cancer (IARC), and methods used by epidemiologists. The criteria are applied to two cases of putative occupational diseases; breast cancer caused by shift work and aerotoxic syndrome. Only three of the Hill criteria can be applied to an actual study. Rothman stresses the importance of confounding and alternative explanations than the putative cause. IARC closely follows Hill, but they also incorporate other than epidemiological evidence. Applied to shift work and breast cancer, these results have found moderate evidence for a causal relationship, but applied to the aerotoxic syndrome, there is an absence of evidence of causality. There are no ready to use algorithms for judgement of evidence of causality. Criteria from different sources lead to similar results and can make a conclusion of causality more or less likely.

2012-01-01

The risk of work-related stress has been determined in bus drivers and workers employed in the service department of two urban and suburban public transportation companies. The INAIL evaluation method (Check list and HSE indicator tool) was used. The GHQ-12 questionnaire, which is widely used to assess the level of psychological distress, was also employed. 81.9% of workers involved in the survey answered both the HSE indicator tool and the GHQ-12 questionnaire. The Check list evaluation showed an increase in quantifiable company stress indicators while close examination using the HSE indicator tool demonstrated critical situations for all the subscales, with the control subscales more problematic in bus drivers. The demand, manager's support, relationships and change subscales were most associated with psychological distress in bus drivers, while relationships, role, change and demand subscales were negatively related in workers of the service department.

Adult siblings of individuals with Down syndrome versus with autism: findings from a large-scale US survey.

Hodapp, R M; Urbano, R C

2007-12-01

As adults with Down syndrome live increasingly longer lives, their adult siblings will most likely assume caregiving responsibilities. Yet little is known about either the sibling relationship or the general functioning of these adult siblings. Using a national, web-based survey, this study compared adult siblings of individuals with Down syndrome to siblings of individuals with autism in terms of a potential 'Down syndrome advantage' and changes across age of the brother/sister with disabilities. Two groups were examined, siblings of persons with Down syndrome (n = 284) and with autism (n = 176). The Adult Sibling Questionnaire measured the number and length of contacts between siblings and their brothers/sisters with disabilities; the warmth, closeness and positiveness of the sibling relationship; and the sibling's overall levels of perceived health, depression and rewards of being a sibling. Compared with siblings of brothers/sisters with autism, siblings of brothers/sisters with Down syndrome showed closer, warmer sibling relationships, along with slightly better health, lower levels of depressive symptoms and more contacts. Across age groups of the brother/sister with disabilities, both groups showed lessened contacts, with less close sibling relationships occurring when brothers/sisters with disabilities were aged 30-44 years and 45 years and older (in Down syndrome) and 45 years and older (in autism). Within both groups, closer sibling relationships were associated with more frequent and lengthy contacts, brothers/sisters with disabilities who were better at maintaining friendships and had lower levels of behavioural/emotional problems, and siblings who felt themselves more rewarded by being a sibling to a brother/sister with disabilities. In line with earlier work on families of children with disabilities, this study shows an advantage for siblings of adults with Down syndrome, in terms of both sibling relationships and of slightly better health and lessened depressive symptoms. Both joint contacts and close sibling relationships do, however, differ when the brother/sister with disabilities is older. As the first generation of probable caregivers, siblings of persons with Down syndrome who are in their forties, fifties and sixties require increased research attention.

Care, Autonomy, and Gender in Nursing Practice: A Historical Study of Nurses' Experiences.

PubMed

Galbany-Estragués, Paola; Comas-d'Argemir, Dolors

2017-10-01

Care is the essence of the nursing role and is closely related to the concept of professional autonomy. Autonomy is implicated in power relations between doctors and nurses and between men and women. These relationships are closely linked to care practices and the inequality of nursing and medicine. The aim of this study was to analyze nursing discourse regarding the concept of care and its relationship to the concept of autonomy and gender. This is a historical study based on oral interviews that took place between November 2008 and February 2011. We interviewed 19 nursing professionals who currently worked at the Hospital of the Holy Spirit (near Barcelona) or had worked there between 1961 and 2010. Semistructured interviews were recorded, transcribed, and analyzed. We highlight four main themes: "a real nurse"; "more technology, less care"; "the fragility of autonomy"; and "the invisibility of nursing work." These themes show the contradictions in the nursing profession that are based on the concept of care. However, in daily practice, the concept of care varies. Time pressure distances the nursing practice from its theoretical context. Changes in the concept of care are related to transformations in the health system and nursing work. Changes related to the autonomy of nursing are related to changes in the concept of care. In practice, care has a biomedical orientation. Care has become technologized and bureaucratized, which reduces the time that is spent with the patient. In a context in which medical authority predominates, nursing's struggle for autonomy is based on the recognition of the value of care. When care becomes invisible, the autonomy of nursing as a profession is threatened. This conclusion allows reflections about shifts in the concept of care and how they affect clinical practice and the autonomy of the nursing profession.

Comparing chronic interpersonal and noninterpersonal stress domains as predictors of depression recurrence in emerging adults.

Sheets, Erin S; Craighead, W Edward

2014-12-01

Understanding how persistent interpersonal difficulties distinctly affect the course of major depressive disorder (MDD) during emerging adulthood is critical, given that early experiences impact future coping resources and functioning. Research on stress and MDD has mostly concentrated on stressful life events, while chronic stress largely has not been explored. The present study examined interpersonal (intimate relationship, close friendships, social life, family relationships) and noninterpersonal (academic, work, financial, personal health, and family members' health) domains of chronic stress as time-varying predictors of depressive recurrence in emerging adults. Baseline assessments identified previously depressed emerging adults (N = 119), who subsequently completed 6-month, 12-month and 18-month follow-up interviews to determine chronic stress experiences and onset of new major depressive episodes. Survival analyses indicated that time-varying total chronic stress and chronic interpersonal stress predicted higher risk for depression recurrence; however, chronic noninterpersonal stress was not associated with recurrence. Intimate relationship stress, close friendship stress, family relationship stress, personal health, and family members' health independently predicted MDD recurrence, over and above well-established depression risk factors of dysfunctional cognitions and personality disorder symptoms. Evidence that interpersonal stress could have substantial impact on course of depression is consistent with theories of emerging adulthood, a time when young people are individuating from the family and experiencing significant social transition.

[Lou Andreas-Salome (1861-1937)--psychoanalytical and feministic contribution to understanding her biography].

PubMed

Bramness, J G

2001-06-30

Lou (Louise) Andreas-Salomé's life and work has preoccupied many biographers. The interest may have be sparked by her liaisons with many of the greatest men of her time. She had an intimate relationship with Friedrich Nietzsche in a period of great change for him. She was Rainer Marie Rilke's mistress for several years. And she pursued a close friendship and working relationship with Sigmund Freud in the latter part of her life. But her significance goes beyond these associations. She was a celebrated novelist and essayist in her own right, with ten novels and more than 50 essays, also on psychoanalytical subjects. She has been viewed as femme fatale, opportunist, feminist, radical, liberal, but also as a significant contributor to psychoanalytical thought. There have been two biographical approaches: a psychoanalytical approach focusing on her loss of father-figures and later difficult relationships with famous men, and a feministic approach accusing psychoanalysts of not contributing to insight, but belittling Salomé's legitimate position. A fuller understanding may be obtained by integrating these two views.

Interdependence of attachment styles and relationship quality in parent-adolescent dyads.

Chow, Chong Man; Hart, Ellen; Ellis, Lillian; Tan, Cin Cin

2017-12-01

The current study examined how attachment styles of parents and adolescents may jointly influence the quality of their relationship. Parent-adolescent (N dyads  = 77) pairs were recruited from a Midwestern town in the United States. The mean of adolescents' age was 16.25. Both members reported their attachment styles, relationship closeness, and relationship discord. The Actor-Partner Interdependence Model (APIM) showed that both members' attachment avoidance was associated with self-report lower levels of closeness. Parents' attachment anxiety was related to relationship discord. Parents with higher avoidant attachment reported lower closeness when adolescents were higher in avoidant attachment. Higher parents' anxious attachment was related to higher relationship closeness when adolescents were higher on anxious attachment. Such an association was negative when adolescents had lower anxious attachment. Higher parents' anxious attachment was related to greater discord when adolescents were lower on anxiety attachment. This study reveals the complex dyadic dynamics of relationship quality in parent-adolescent pairs. Copyright © 2017 The Foundation for Professionals in Services for Adolescents.

This study sought to identify ways in which adolescent attachment security, as assessed via the Adult Attachment Interview, is manifest in qualities of the secure base provided by the mother–adolescent relationship. Assessments included data coded from mother–adolescent interactions, test-based data, and adolescent self-reports obtained from an ethnically and socioeconomically diverse sample of moderately at-risk 9th and 10th graders. This study found several robust markers of adolescent attachment security in the mother–adolescent relationship. Each of these markers was found to contribute unique variance to explaining adolescent security, and in combination, they accounted for as much as 40% of the raw variance in adolescent security. These findings suggest that security is closely connected to the workings of the mother–adolescent relationship via a secure-base phenomenon, in which the teen can explore independence in thought and speech from the secure base of a maternal relationship characterized by maternal attunement to the adolescent and maternal supportiveness.

Narrative and attachment in the process of recovery from substance misuse.

Waters, Kathryn; Holttum, Sue; Perrin, Ines

2014-06-01

The aim of this study was to illustrate the individual accounts of a small group of substance misusers who had found psychological therapy helpful in their recovery from substance misuse. The study also aimed to highlight the roles that the psychologists played within these narratives. Narrative analysis, a qualitative design, was used to capture the unique recovery narratives of substance users who had received psychological therapy. Seven participants (three males and four females, age range 40-54 years, six White British, one White European) were recruited via clinical psychologists from an addictions psychology department and participated in 60-90 min interviews. Analysis of the recovery narratives resulted in an overarching theme; role of the psychologists as a secure attachment figure leading to the development of surrogate internal working models, and the following subthemes which developed and maintained the attachments: closeness and proximity leading to positive expectations about the relationship, safe haven leading to increasing capacities for affect regulation, secure base leading to the experience of being able to mentalize regarding ones mental states and associated actions, and separation distress leading to internalizing the psychologists. The study analysed the personal accounts of seven substance misusers regarding their use of psychological therapy in their recovery. The relationship between the therapists and the clients developed as a result of the psychologists serving as secure attachment figures, and providing closeness and proximity, a safe haven and a secure base to the clients. Clients' separation distress also led to the internalizing of the psychologists. Future studies are needed to tease out which substance user clients would most be suited to the above approach. Measures of newer more adaptive internal working models could then be applied to relationships outside of therapy to see in what way the newer, more flexible, and transferable IWMs were truly internalized and influential in the recovering minds of substance misusers. Clinical Psychologists can play a vital role in the recovery of substance misusers who are ready to work through their psychological recovery. Forming a positive therapeutic relationship is dependent on the psychologists fulfilling the role of positive attachment figures for the clients. © 2013 The British Psychological Society.

Association of working hours with biological indices related to the cardiovascular system among engineers in a machinery manufacturing company.

PubMed

Sasaki, T; Iwasaki, K; Oka, T; Hisanaga, N

1999-10-01

A field survey of 278 engineers (20-59 years) in a machinery manufacturing company was conducted to investigate the association of working hours with biological indices related to the cardiovascular system (heart rate variability, blood pressure and serum levels of magnesium, dehydroepiandrosterone sulfate and cholesterol). Average working hours (defined as <"hours at workplace" + "half a commuting time">) and sleeping hours in this study were 60.2 +/- 6.3 hr/week and 6.6 +/- 0.8 hr/day respectively. There were no significant relationships between working hours and biological indices related to the cardiovascular system, but sleeping hours was closely related to working hours negatively. Furthermore, the serum DHEA-S level was significantly related to sleeping hours positively. Combining these two results, it appeared that long working hours might lower the serum DHEA-S level due to the reduction of sleeping hours.

ATTACHMENT AND CORE RELATIONSHIP THEMES: WISHES FOR AUTONOMY AND CLOSENESS IN THE NARRATIVES OF SECURELY AND INSECURELY ATTACHED ADULTS

PubMed Central

Waldinger, Robert J.; Seidman, Ethan L.; Gerber, Andrew J.; Liem, Joan H.; Allen, Joseph P.; Hauser, Stuart T.

2006-01-01

This study examines links between attachment states of mind and relationship schemas in a sample of 40 young adults, half of whom were hospitalized as adolescents for psychiatric treatment. Participants were interviewed about their closest relationships, and, using the Core Conflictual Relationship Theme method, their narratives about these relationships were analyzed for the relative frequency with which they expressed wishes for closeness and for autonomy in relation to others. Participants were also administered the Adult Attachment Interview and were classified with respect to security of attachment. Security of attachment was associated with the relative frequency with which participants expressed wishes for autonomy in their narratives about close relationships, even after accounting for current levels of psychological functioning and history of serious psychopathology in adolescence. Security of attachment was not associated with the relative frequency with which participants expressed wishes for closeness. The study suggests that core relational wishes for autonomy are linked specifically with subtypes of insecure attachment. These findings extend what is known about connections between the representation of early attachment relationships and the wishes and needs expressed in current relationships with significant others.

Comparing estimates of genetic variance across different relationship models.

PubMed

Legarra, Andres

2016-02-01

Use of relationships between individuals to estimate genetic variances and heritabilities via mixed models is standard practice in human, plant and livestock genetics. Different models or information for relationships may give different estimates of genetic variances. However, comparing these estimates across different relationship models is not straightforward as the implied base populations differ between relationship models. In this work, I present a method to compare estimates of variance components across different relationship models. I suggest referring genetic variances obtained using different relationship models to the same reference population, usually a set of individuals in the population. Expected genetic variance of this population is the estimated variance component from the mixed model times a statistic, Dk, which is the average self-relationship minus the average (self- and across-) relationship. For most typical models of relationships, Dk is close to 1. However, this is not true for very deep pedigrees, for identity-by-state relationships, or for non-parametric kernels, which tend to overestimate the genetic variance and the heritability. Using mice data, I show that heritabilities from identity-by-state and kernel-based relationships are overestimated. Weighting these estimates by Dk scales them to a base comparable to genomic or pedigree relationships, avoiding wrong comparisons, for instance, "missing heritabilities".

Balancing authority, deference and trust across the public–private divide in health care: Tuberculosis health visitors in western Maharashtra, India

Kielmann, Karina; Datye, Vinita; Pradhan, Anagha; Rangan, Sheela

2014-01-01

While concepts such as ‘partnership’ are central to the terminology of private–public mix (PPM), little attention has been paid to how social relations are negotiated among the diverse actors responsible for implementing these inter-sectoral arrangements. India's Revised National Tuberculosis Control Programme (RNTCP) has used intermediary agents to facilitate the involvement of private providers in the expansion of Directly Observed Therapy, Short-Course (DOTS). We examine the roles of tuberculosis health visitors (TB HVs) in mediating working relationships among private providers, programme staff and patients that underpin a PPM-DOTS launched by the RNTCP in western Maharashtra. In addition to observations and informal interactions with the programme and participating health providers, researchers conducted in-depth interviews with senior programme officers and eight TB HVs. Framed by a political discourse of clinical governance, working relationships within the PPM are structured by the pluralistic context, social and professional hierarchies and paternalism of health care in India. TB HVs are at the nexus of these relationships, yet remain undervalued partly because accountability is measured through technical rather than social outcomes of the ‘partnership’. Close attention to the dynamics of power relations in working practices within the health system can improve accountability and sustainability of partnerships. PMID:25147003

Modeling Advance Life Support Systems

1996-01-01

Activities this summer consisted of two projects that involved computer simulation of bioregenerative life support systems for space habitats. Students in the Space Life Science Training Program (SLSTP) used the simulation, space station, to learn about relationships between humans, fish, plants, and microorganisms in a closed environment. One student complete a six week project to modify the simulation by converting the microbes from anaerobic to aerobic, and then balancing the simulation's life support system. A detailed computer simulation of a closed lunar station using bioregenerative life support was attempted, but there was not enough known about system restraints and constants in plant growth, bioreactor design for space habitats and food preparation to develop an integrated model with any confidence. Instead of a completed detailed model with broad assumptions concerning the unknown system parameters, a framework for an integrated model was outlined and work begun on plant and bioreactor simulations. The NASA sponsors and the summer Fell were satisfied with the progress made during the 10 weeks, and we have planned future cooperative work.

Emotional boundary work in advanced fertility nursing roles.

PubMed

Allan, Helen; Barber, Debbie

2005-07-01

In this article we examine the nature of intimacy and knowing in the nurse-patient relationship in the context of advanced nursing roles in fertility care. We suggest that psychoanalytical approaches to emotions may contribute to an increased understanding of how emotions are managed in advanced nursing roles. These roles include nurses undertaking tasks that were formerly performed by doctors. Rather than limiting the potential for intimacy between nurses and fertility patients, we argue that such roles allow nurses to provide increased continuity of care. This facilitates the management of emotions where a feeling of closeness is created while at the same time maintaining a distance or safe boundary with which both nurses and patients are comfortable. We argue that this distanced or 'bounded' relationship can be understood as a defence against the anxiety of emotions raised in the nurse-fertility patient relationship.

Maintaining close relationships: gratitude as a motivator and a detector of maintenance behavior.

PubMed

Kubacka, Kaska E; Finkenauer, Catrin; Rusbult, Caryl E; Keijsers, Loes

2011-10-01

This research examined the dual function of gratitude for relationship maintenance in close relationships. In a longitudinal study among married couples, the authors tested the dyadic effects of gratitude over three time points for approximately 4 years following marriage. They found that feelings of gratitude toward a partner stem from the partner's relationship maintenance behaviors, partly because such behaviors create the perception of responsiveness to one's needs. In turn, gratitude motivates partners to engage in relationship maintenance. Hence, the present model emphasizes that gratitude between close partners (a) originates from partners' relationship maintenance behaviors and the perception of a partner's responsiveness and (b) promotes a partner's reciprocal maintenance behaviors. Thus, the authors' findings add credence to their model, in that gratitude contributes to a reciprocal process of relationship maintenance, whereby each partner's maintenance behaviors, perceptions of responsiveness, and feelings of gratitude feed back on and influence the other's behaviors, perceptions, and feelings.

"Going out" of the box: Close intercultural friendships and romantic relationships spark creativity, workplace innovation, and entrepreneurship.

The present research investigates whether close intercultural relationships promote creativity, workplace innovation, and entrepreneurship-outcomes vital to individual and organizational success. We triangulate on these questions with multiple methods (longitudinal, experimental, and field studies), diverse population samples (MBA students, employees, and professional repatriates), and both laboratory and real-world measures. Using a longitudinal design over a 10-month MBA program, Study 1 found that intercultural dating predicted improved creative performance on both divergent and convergent thinking tasks. Using an experimental design, Study 2 established the causal connection between intercultural dating and creativity: Among participants who had previously had both intercultural and intracultural dating experiences, those who reflected on an intercultural dating experience displayed higher creativity compared to those who reflected on an intracultural dating experience. Importantly, cultural learning mediated this effect. Extending the first 2 studies, Study 3 revealed that the duration of past intercultural romantic relationships positively predicted the ability of current employees to generate creative names for marketing products, but the number of past intercultural romantic partners did not. In Study 4, we analyzed an original dataset of 2,226 professional repatriates from 96 countries who had previously worked in the U.S. under J-1 visas: Participants' frequency of contact with American friends since returning to their home countries positively predicted their workplace innovation and likelihood of becoming entrepreneurs. Going out with a close friend or romantic partner from a foreign culture can help people "go out" of the box and into a creative frame of mind.

Dog Breed Differences in Visual Communication with Humans.

Konno, Akitsugu; Romero, Teresa; Inoue-Murayama, Miho; Saito, Atsuko; Hasegawa, Toshikazu

2016-01-01

Domestic dogs (Canis familiaris) have developed a close relationship with humans through the process of domestication. In human-dog interactions, eye contact is a key element of relationship initiation and maintenance. Previous studies have suggested that canine ability to produce human-directed communicative signals is influenced by domestication history, from wolves to dogs, as well as by recent breed selection for particular working purposes. To test the genetic basis for such abilities in purebred dogs, we examined gazing behavior towards humans using two types of behavioral experiments: the 'visual contact task' and the 'unsolvable task'. A total of 125 dogs participated in the study. Based on the genetic relatedness among breeds subjects were classified into five breed groups: Ancient, Herding, Hunting, Retriever-Mastiff and Working). We found that it took longer time for Ancient breeds to make an eye-contact with humans, and that they gazed at humans for shorter periods of time than any other breed group in the unsolvable situation. Our findings suggest that spontaneous gaze behavior towards humans is associated with genetic similarity to wolves rather than with recent selective pressure to create particular working breeds.

Burnout, psychosomatic symptoms and job satisfaction among Dutch nurse anaesthetists: a survey.

2010-05-01

To meet the increasing demand for healthcare providers, it is crucial to recruit and retain more nurse anaesthetists (NAs). The majority of NAs in the Netherlands are >45 years old, and retaining them in their jobs is very important. This study investigates the relationships among burnout, physical health and job satisfaction among Dutch NAs. Two thousand NAs working in Dutch hospitals were invited to participate in this online questionnaire. We tested the relationships among burnout, psychosomatic symptoms, sickness absence, perceived general health and job satisfaction. Nine hundred and twenty-three questionnaires were completed and analysed (46% response rate). Burnout and psychosomatic symptoms were negatively associated with job satisfaction, and predicted 27% of job satisfaction. Perceived general health was positively and sickness absence was negatively related to job satisfaction. Older NAs had a higher incidence of burnout than their younger counterparts. The results confirmed the importance of a healthy psychosocial work environment for promoting job satisfaction. To prevent burnout, further research is necessary to determine the factors causing stress. These findings may also apply to anaesthesiologists who share many tasks and work in close cooperation with NAs.

To examine the association between degree of real-life closeness of social media (SM) contacts and depressive symptoms. Students ages 18-30 (N = 1124) were recruited in August 2016. Participants completed an online survey assessing SM use and depression. We used multivariable logistic regression to assess associations between real-life closeness of SM contacts and depressive symptoms. After controlling for covariates, each 10% increase in the proportion of SM friends with whom participants had no face-to-face relationship was associated with a 9% increase in odds of depressive symptoms (AOR = 1.09; 95% CI = 1.05-1.13). However, each 10% increase in the proportion of SM friends with whom participants had a close face-to-face relationship was associated with a 7% decrease in depressive symptoms (AOR = 0.93; 95% CI = 0.89-0.97). Having no in-person relationship with SM contacts is associated with increased depressive symptoms; however, having close in-person relationships with SM contacts is associated with decreased depressive symptoms.

Memory as Social Glue: Close Interpersonal Relationships in Amnesic Patients

Memory may be crucial for establishing and/or maintaining social bonds. Using the National Social life, Health, and Aging Project questionnaire, we examined close interpersonal relationships in three amnesic people: K.C. and D.A. (who are adult-onset cases) and H.C. (who has developmental amnesia). All three patients were less involved than demographically matched controls with neighbors and religious and community groups. A higher-than-normal percentage of the adult-onset (K.C. and D.A.) cases’ close relationships were with family members, and they had made few new close friends in the decades since the onset of their amnesia. On the other hand, the patient with developmental amnesia (H.C.) had forged a couple of close relationships, including one with her fiancé. Social networks appear to be winnowed, but not obliterated, by amnesia. The obvious explanation for the patients’ reduced social functioning stems from their memory impairment, but we discuss other potentially important factors for future study. PMID:23316176

Social and emotional patterns in adulthood: support for socioemotional selectivity theory.

PubMed

Carstensen, L L

1992-09-01

This investigation explored 2 hypotheses derived from socioemotional selectivity theory: (a) Selective reductions in social interaction begin in early adulthood and (b) emotional closeness to significant others increases rather than decreases in adulthood even when rate reductions occur. Transcribed interviews with 28 women and 22 men from the Child Guidance Study, conducted over 34 years, were reviewed and rated for frequency of interaction, satisfaction with the relationship, and degree of emotional closeness in 6 types of relationships. Interaction frequency with acquaintances and close friends declined from early adulthood on. Interaction frequency with spouses and siblings increased across the same time period and emotional closeness increased throughout adulthood in relationships with relatives and close friends. Findings suggest that individuals begin narrowing their range of social partners long before old age.

Maternal well-being and child behavior in families with fragile X syndrome.

2014-10-01

The purpose of this study was to examine the bidirectional relationships relationship between maternal mental health status, maternal stress, family environment and behavioral functioning of children with fragile X syndrome (FXS), the leading cause of inherited intellectual disability. Children with FXS commonly demonstrate challenging behavior related to anxiety, attention, and aggression, whereas mothers of children with FXS have been identified as susceptible to mental health challenges due to their status as genetic carriers of the FXS premutation, as well as the environmental stressors of raising children with special needs. The longitudinal design of this study builds upon prior work that established a concurrent relationship among these factors in families of children with other intellectual disorders. Findings indicated that maternal mental health status was not significantly related to changes in levels of child challenging behavior, heightened child challenging behavior was related to improvements in maternal depression over time, and heightened levels of child challenging behavior was related to increased feelings of maternal closeness toward the child over time. The unexpected nature of the results regarding maternal depression and closeness provides new and more complex hypotheses about how mothers of special needs children demonstrate adaptation and resilience. The findings have implications for maternal and familial mental health treatment as well as future research. Copyright © 2014 Elsevier Ltd. All rights reserved.

2012-04-01

There have been major changes to the medical care system and heightened standards for quality in the nursing profession in recent decades. Multifunctional capabilities are closely related to individual working attitudes, and work satisfaction directly affects group performance. Hospital administrators increasingly expect to utilize nursing staffs flexibly in terms of working hours and shift rotation assignments. This study addresses the need to provide appropriate educational training to nurses and effectively delegate and utilize human resources in order to help nurses adapt to the rapidly changing medical environment. This study on nursing staff in Tainan area explored the relationships between job rotation, work performance and satisfaction. We used a questionnaire sampling method to survey nurses working in the Tainan area of southern Taiwan. Subjects were volunteers and a total 228 valid questionnaires (99.13%) were returned out of a total 230 sent. Both job satisfaction and performance correlated positively with job rotation perception and intention; Job satisfaction and job performance were positively related; Job satisfaction was found to affect work performance via job rotation perception and intention. This study found the hospital nursing staff rotation plan to be an effective management method that facilitates social evolution to increase positive perceptions of work rotation. Nursing staffs thus become more accepting of new positions that may enhance job satisfaction.

2013-08-01

This study tested a theoretical model considering students' personality traits as predictors of student-teacher relationship quality (closeness, conflict, and dependency), the effects of student-teacher relationship quality on students' math and reading achievement, and the mediating role of students' motivational beliefs on the association between student-teacher relationship quality and achievement in upper elementary school. Surveys and tests were conducted among a nationally representative Dutch sample of 8545 sixth-grade students and their teachers in 395 schools. Structural equation models were used to test direct and indirect effects. Support was found for a model that identified conscientiousness and agreeableness as predictors of close, nonconflictual relationships, and neuroticism as a predictor of dependent and conflictual relationships. Extraversion was associated with higher levels of closeness and conflict, and autonomy was only associated with lower levels of dependency. Students' motivational beliefs mediated the effects of dependency and student-reported closeness on reading and math achievement. Copyright © 2013 Society for the Study of School Psychology.

Students learning from patients: let's get real in medical education.

PubMed

Bleakley, Alan; Bligh, John

2008-03-01

Medical students must be prepared for working in inter-professional and multi-disciplinary clinical teams centred on a patient's care pathway. While there has been a good deal of rhetoric surrounding patient-centred medical education, there has been little attempt to conceptualise such a practice beyond the level of describing education of communication skills and empathy within a broad 'professionalism' framework. Paradoxically, while aiming to strengthen patient-student interactions, this approach tends to refocus on the role modelling of the physician, and opportunities for potentially deep collaborative working relationships between students and patients are missed. A radical overhaul of conventional doctor-led medical education may be necessary, that also challenges the orthodoxies of individualistic student-centred approaches, leading to an authentic patient-centred model that shifts the locus of learning from the relationship between doctor as educator and student to the relationship between patient and student, with expert doctor as resource. Drawing on contemporary poststructuralist theory of text and identity construction, and on innovative models of work-based learning, the potential quality of relationship between student and patient is articulated in terms of collaborative knowledge production, involving close reading with the patient as text, through dialogue. Here, a medical 'education' displaces traditional forms of medical 'training' that typically involve individual information reproduction. Students may, paradoxically, improve clinical acumen through consideration of silences, gaps, and contradictions in patients as texts, rather than treating communication as transparent. Such paradoxical effects have been systematically occluded or denied in traditional medical education.

Quality of Relationships with Parents and Friends in Adolescence Predicts Metabolic Risk in Young Adulthood

2015-01-01

Objective The present study was designed to examine whether family and peer relationships in adolescence predict the emergence of metabolic risk factors in young adulthood. Methods Participants from a large, nationally representative cohort study (N = 11,617 for these analyses) reported on their relationship experiences with parents and close friends during adolescence. Fourteen years later, interviewers collected blood samples, as well as anthropometric and blood pressure measurements. Blood samples were analyzed for HbA1c. Results Ordered logistic regressions revealed that for females, supportive parent-child relationships and close male friendships in adolescence were associated with reduced odds of having elevated metabolic risk markers in young adulthood. These effects remained significant even after controlling for baseline measures of body mass index (BMI) and health and demographic covariates. The protective effects of close relationships were not significant for males, however. Exploratory analyses with two-parent families revealed that supportive father-child relationships were especially protective for females. Conclusions These findings suggest that, for females, close and supportive relationships with parents and male friends in adolescence may reduce the risk of metabolic dysregulation in adulthood.

The Role of Close Relationships in Terror Management: A Systematic Review and Research Agenda.

PubMed

Plusnin, Nicholas; Pepping, Christopher A; Kashima, Emiko S

2018-02-01

Terror management theory outlines how humans seek self-esteem and worldview validation to manage death-related anxiety. Accumulating evidence reveals that close relationships serve a similar role. However, to date, there has been no synthesis of the literature that delineates when close relationships buffer mortality concerns, under what conditions, on which specific outcomes, and for whom. This systematic review presents over two decades of research to address these questions. Findings from 73 reviewed studies revealed that close relationships serve an important role in buffering death-related anxiety. A range of dispositional and situational moderating factors influence either the activation or inhibition of relational strivings to manage heightened death awareness, the most influential being attachment, gender, and relationship-contingent self-esteem. These findings were integrated into an overarching model that highlights some of the conditions under which mortality salience (MS) influences relational outcomes. We conclude by highlighting a range of theoretical and methodological concerns to be addressed by future research.

Dogs’ attention towards humans depends on their relationship, not only on social familiarity

PubMed Central

Horn, Lisa; Range, Friederike; Huber, Ludwig

2014-01-01

Both in humans and non-human animals it has been shown that individuals attend more to those they have previously interacted with and/or that they are more closely associated with than to unfamiliar individuals. Whether this preference is mediated by mere social familiarity based on exposure or by the specific relationship between the two individuals, however, remains unclear. The domestic dog is an interesting subject in this line of research as it lives in the human environment and regularly interacts with numerous humans, yet it often has a particularly close relationship with its owner. Therefore, we investigated how long dogs (Canis familiaris) would attend to the actions of two familiar humans and one unfamiliar experimenter, while varying whether dogs had a close relationship with only one or both familiar humans. Our data provide evidence that social familiarity by itself cannot account for dogs’ increased attention towards their owners since they only attended more to those familiar humans with whom they also had a close relationship.

Although impulsivity, sensation-seeking, and part-time employment have each been linked to risky behaviors in adolescents, their inter-relationships are less well-understood. We examined data from adolescents to assess the following predictions: (1) sensation-seeking would relate closely to substance use and gambling; (2) impulsivity would relate closely to alcohol, drug, and gambling problems; and (3) these relationships would be particularly strong among those holding part-time jobs. High-school students (N = 3,106) were surveyed to provide data on impulsivity, sensation-seeking, and part-time job status. Bivariate and logistic regression analyses were conducted to examine relationships with gambling, substance use (i.e., alcohol, cigarettes, and marijuana) and related problems. Both impulsivity and sensation-seeking related significantly to substance use and impulsivity to gambling. Impulsivity had stronger associations with drug and gambling problems than sensation-seeking did. Students with paid part-time jobs were more likely to drink alcohol, binge drink, and use marijuana. Sensation-seeking had a particularly strong relationship to heavy cigarette smoking among students with part-time jobs. Conversely, there was little relationship between part-time job status and smoking among low sensation-seekers. These findings further support the relevance of sensation-seeking, impulsivity, and part-time job status to risky behaviors among adolescents. Sensation-seeking and impulsivity had unique relationships to risky behaviors, in accordance with theory and prior evidence. Impulsive adolescents may be in particular need for interventions to reduce drug use and gambling. Although part-time jobs can be beneficial, parents and caregivers should be mindful of potential negative ramifications of paid work outside the home.

Attachment theories and studies have shown that Internal Working Models (IWMs) can impact autobiographical memory and future-oriented information processing relevant to close relationships. According to the constructive episodic simulation hypothesis (CESH), both remembering the past and imagining the future rely on episodic memory. We hypothesised that one way IWMs may bridge past experiences and future adaptations is via episodic memory. The present study investigated the association between attachment and episodic specificity in attachment-relevant and attachment-irrelevant memory and imagination among young and older adults. We measured the attachment style of 37 young adults and 40 older adults, and then asked them to remember or imagine attachment-relevant and attachment-irrelevant events. Participants' narratives were coded for internal details (i.e., episodic) and external details (e.g., semantic, repetitions). The results showed that across age group, secure individuals generated more internal details and fewer external details in attachment-relevant tasks compared to attachment-irrelevant tasks; these differences were not observed in insecure individuals. These findings support the CESH and provide a new perspective to understand the function of IWMs.

O-Antigen (O-polysaccharide) variation is the basis for bacterial serotyping and is important in bacterial virulence and niche adaptation. In this work, we present structural and genetic evidences for close relationships between the O-antigens of the Cronobacter spp. and Escherichia coli. Cronobacter sakazakii G2594 (serotype O4) and Cronobacter malonaticus G3864 (serotype O1) are structurally related to those of E. coli O103 and O29, respectively, and some other members of the Enterobacteriaceae family differing in the patterns of lateral glucosylation (C. sakazakii G2594) or O-acetylation (C. malonaticus G3864). The O-antigen gene clusters of the corresponding Cronobacter and E. coli strains contain the same genes with high-level similarity, and the structural differences within both O-antigen pairs were suggested to be due to modification genes carried by prophages.

Somense, Carolina Bueno; Duran, Erika Christiane Marocco

2014-09-01

The present study aimed to identify hygienic and motivational factors in the nursing work according to the Two-Factor Theory, as well as their relation with professional satisfaction/dissatisfaction. This exploratory-descriptive study involved nine nurses from the cardiology ward of a hospital in the interior of the State of São Paulo, between August and September 2013. A self-applied questionnaire was used, including open and closed questions. The data were categorized as hygienic and motivational. Results show the nurses' satisfaction with autonomy, work itself and teamwork, duties, content and responsibilities of the job. Dissatisfaction is related to career growth possibilities; work, political and administrative conditions at the institution, supervision and lack of institutional support. Satisfaction and dissatisfaction factors include relationships, acknowledgements and remuneration. Nurses' satisfaction is determined by multiple and often controversial factors.

Work engagement in nursing practice: a relational ethics perspective.

PubMed

Keyko, Kacey

2014-12-01

The concept of work engagement has existed in business and psychology literature for some time. There is a significant body of research that positively correlates work engagement with organizational outcomes. To date, the interest in the work engagement of nurses has primarily been related to these organizational outcomes. However, the value of work engagement in nursing practice is not only an issue of organizational interest, but of ethical interest. The dialogue on work engagement in nursing must expand to include the ethical importance of engagement. The relational nature of work engagement and the multiple levels of influence on nurses' work engagement make a relational ethics approach to work engagement in nursing appropriate and necessary. Within a relational ethics perspective, it is evident that work engagement enables nurses to have meaningful relationships in their work and subsequently deliver ethical care. In this article, I argue that work engagement is essential for ethical nursing practice. If engagement is essential for ethical nursing practice, the environmental and organizational factors that influence work engagement must be closely examined to pursue the creation of moral communities within healthcare environments. © The Author(s) 2014.

The purpose of this study was to examine the relationships of sexual minority youth and their siblings. The participants were 56 lesbian, gay, bisexual, or transgender individuals ranging in age from 18 to 24 years, who reported information about a total of 107 siblings. Respondents completed a demographic data questionnaire as well as adapted versions of the Sibling Closeness Scale (SCS) and the Sibling Approval of Sexual Behavior Scale (SASBS) to describe their relationship with each of their siblings. Analyses examined birth order and gender in relation to outness to siblings as well as sibling closeness and approval. Results provide information about disclosure of LGBT status to siblings, elements of closeness and acceptance in sibling relationships of sexual minority youth, and the significance of gender and birth order in these sibling relationships.

The present study had three main objectives: (1) to develop and validate scales of young adult social competence in two domains, close relationships and social groups, using peer ratings of California Q-sort (Block, 1974; Kremen & Block, 2002) items; (2) to test the hypothesis that social competence is associated with young adult well-being and ego development; (3) to test the hypothesis that close relationship competence aligns more closely than social group competence with young adult functioning. Psychometric data on peer ratings of social competence are presented. For 133 young adults, peer ratings of social competence were correlated in expected directions with indices of functioning (e.g., self-worth, education, psychological distress, criminal behavior, and ego development). Associations were generally stronger for competence in close relationships than in social groups. PMID:17764391

Enhancing US-Japan Cooperation to Combat Antimicrobial Resistance

PubMed Central

2014-01-01

The Global Health Security Agenda (GHSA) is aimed at preventing, detecting, and responding to infectious disease threats. To move toward these goals, the United States has committed to partner with at least 30 countries around the world. One of the objectives of the GHSA includes “[p]reventing the emergence and spread of antimicrobial drug resistant organisms.” Antimicrobial resistance (AMR) has become a growing global health security problem, with inappropriate use of antimicrobial medications in humans and animals and a lack of new antimicrobial medications contributing to this problem. While AMR is a growing global concern, working on it regionally can make this multifaceted problem more manageable. The United States and Japan, both world leaders in the life sciences, are close allies that have established cooperative programs in medical research and global health that can be used to work on combating AMR and advance the GHSA. Although the United States and Japan have cooperated on health issues in the past, their cooperation on the growing problem of AMR has been limited. Their existing networks, cooperative programs, and close relationships can and should be used to work on combating this expanding problem. PMID:25470465

The purpose of this study was to examine the relationship nursing personal and workplace system factors (work disability) and work ability index scores in Ontario, Canada. A total of 111 registered nurses were randomly selected from the total number of registered nurses on staff in the labor, delivery, recovery, and postpartum areas of four northeastern Ontario hospitals. Using a stratified random design approach, 51 participants were randomly selected in four northeastern Ontario cities. A total of 51 (45.9% response rate) online questionnaires were returned and another 60 (54.1% response rate) were completed using the paper format. The obstetric workforce in northeastern Ontario was predominately female (94.6%) with a mean age of 41.9 (standard deviation = 10.2). In the personal systems model, three variables: marital status (p = 0.025), respondent ethnicity (p = 0.026), and mean number of patients per shift (p = 0.049) were significantly contributed to the variance in work ability scores. In the workplace system model, job and career satisfaction (p = 0.026) had a positive influence on work ability scores, while work absenteeism (p = 0.023) demonstrated an inverse relationship with work ability scores. In the combined model, all the predictors were significantly related to work ability scores. Work ability is closely related to job and career satisfaction, and perceived control at work among obstetric nursing. In order to improve work ability, nurses need to work in environments that support them and allow them to be engaged in the decision-making processes.

Out of the lengthy original expression of the diffuse reflectance formula, simple working equations were derived by employing characteristic parameters, which are independent of the canopy coverage and identifiable by field observations. The typical asymptotic nature of reflectance data that is usually observed in biomass studies was clearly explained. The usefulness of the simplified equations was demonstrated by the exceptionally close fit of the theoretical curves to two separately acquired data sets for alfalfa and shortgrass prairie canopies.

Collegial relationship breakdown: a qualitative exploration of nurses in acute care settings.

PubMed

Cowin, Leanne S

2013-01-01

Poor collegial relations can cause communication breakdown, staff attrition and difficulties attracting new nursing staff. Underestimating the potential power of nursing team relationships means that opportunities to create better working environments and increase the quality of nursing care can be missed. Previous research on improving collegiality indicates that professionalism and work satisfaction increases and that staff attrition decreases. This study explores challenges, strengths and strategies used in nursing team communication in order to build collegial relationships. A qualitative approach was employed to gather nurses experiences and discussion of communication within their nursing teams and a constant comparison method was utilised for data analysis. A convenience sampling technique was employed to access both Registered Nurses and Enrolled Nurses to partake in six focus groups. Thirty mostly female nurses (ratio of 5:1) participated in the study. Inclusion criteria consisted of being a nurse currently working in acute care settings and the exclusion criteria included nursing staff currently working in closed specialty units (i.e. intensive care units). Results revealed three main themes: (1) externalisation and internalisation of nursing team communication breakdown, (2) the importance of collegiality for retention of nurses and (3) loss of respect, and civility across the healthcare workplace. A clear division between hierarchies of nurses was apparent in how nursing team communication was delivered and managed. Open, respectful and collegial communication is essential in today's dynamic and complex health environments. The nurses in this study highlighted how important nursing communication can be to work motivation and how leadership fosters teamwork.

This longitudinal study examined developmental links between closeness in teacher-child relationships and children's receptive language ability from the end of the preschool years into the early elementary years, while controlling for changes in peer interaction quality and child behavioral functioning. The sample included children and their parents and teachers (N = 4,983) participating in the Longitudinal Study of Australian Children (LSAC) at ages 4-5, 6-7, and 8-9 years (3 waves). Teachers reported on levels of closeness in relationships with individual children. Independent assessments of receptive language were employed. Parents and teachers reported on peer interaction problems and child conduct problems. Results indicated reciprocal associations between close teacher-child relationships and receptive language development above and beyond associations with peer interaction quality and child behavioral functioning. However, the effects were only modest. PsycINFO Database Record (c) 2015 APA, all rights reserved.

This article reviews empirical studies of same-sex couples in the United States, highlighting consistent findings, drawing comparisons to heterosexual couples, and noting gaps in available research. U.S. Census data indicate that there were more than 600,000 same-sex couples living together in 2000. Research about relationship formation, the division of household labor, power, satisfaction, sexuality, conflict, commitment, and relationship stability is presented. Next, we highlight three recent research topics: the legalization of same-sex relationships through civil unions and same-sex marriage, the experiences of same-sex couples raising children, and the impact of societal prejudice and discrimination on same-sex partners. We conclude with comments about the contributions of empirical research to debunking negative stereotypes of same-sex couples, testing the generalizability of theories about close relationships, informing our understanding of gender and close relationships, and providing a scientific basis for public policy.

Working memory capacity predicts listwise directed forgetting in adults and children.

PubMed

Aslan, Alp; Zellner, Martina; Bäuml, Karl-Heinz T

2010-05-01

In listwise directed forgetting, participants are cued to forget previously studied material and to learn new material instead. Such cueing typically leads to forgetting of the first set of material and to memory enhancement of the second. The present study examined the role of working memory capacity in adults' and children's listwise directed forgetting. Working memory capacity was assessed with complex span tasks. In Experiment 1 working memory capacity predicted young adults' directed-forgetting performance, demonstrating a positive relationship between working memory capacity and each of the two directed-forgetting effects. In Experiment 2 we replicated the finding with a sample of first and a sample of fourth-grade children, and additionally showed that working memory capacity can account for age-related increases in directed-forgetting efficiency between the two age groups. Following the view that directed forgetting is mediated by inhibition of the first encoded list, the results support the proposal of a close link between working memory capacity and inhibitory function.

Molecular evidence for a terrestrial origin of snakes

Vidal, Nicolas; Hedges, S. Blair

Biologists have debated the origin of snakes since the nineteenth century. One hypothesis suggests that snakes are most closely related to terrestrial lizards, and reduced their limbs on land. An alternative hypothesis proposes that snakes are most closely related to Cretaceous marine lizards, such as mosasaurs, and reduced their limbs in water. A presumed close relationship between living monitor lizards, believed to be close relatives of the extinct mosasaurs, and snakes has bolstered the marine origin hypothesis. Here, we show that DNA sequence evidence does not support a close relationship between snakes and monitor lizards, and thus supports a terrestrial origin of snakes.

Finite Element Analysis and Understanding the Biomechanics and Evolution of Living and Fossil Organisms

NASA Astrophysics Data System (ADS)

Rayfield, Emily J.

2007-05-01

Finite element analysis (FEA) is a technique that reconstructs stress, strain, and deformation in a digital structure. Although commonplace in engineering and orthopedic science for more than 30 years, only recently has it begun to be adopted in the zoological and paleontological sciences to address questions of organismal morphology, function, and evolution. Current research tends to focus on either deductive studies that assume a close relationship between form and function or inductive studies that aim to test this relationship, although explicit hypothesis-testing bridges these two standpoints. Validation studies have shown congruence between in vivo or in vitro strain and FE-inferred strain. Future validation work on a broad range of taxa will assist in phylogenetically bracketing our extinct animal FE-models to increase confidence in our input parameters, although currently, FEA has much potential in addressing questions of form-function relationships, providing appropriate questions are asked of the existing data.

Exploring sets of molecules from patents and relationships to other active compounds in chemical space networks

Kunimoto, Ryo; Bajorath, Jürgen

2017-09-01

Patents from medicinal chemistry represent a rich source of novel compounds and activity data that appear only infrequently in the scientific literature. Moreover, patent information provides a primary focal point for drug discovery. Accordingly, text mining and image extraction approaches have become hot topics in patent analysis and repositories of patent data are being established. In this work, we have generated network representations using alternative similarity measures to systematically compare molecules from patents with other bioactive compounds, visualize similarity relationships, explore the chemical neighbourhood of patent molecules, and identify closely related compounds with different activities. The design of network representations that combine patent molecules and other bioactive compounds and view patent information in the context of current bioactive chemical space aids in the analysis of patents and further extends the use of molecular networks to explore structure-activity relationships.

Systematic reviews (SRs) provide high quality evidence for clinical practice, but the article screening process is time and labor intensive. As SRs aim to identify relevant articles with a specific scope, we propose that a pre-defined article relationship, using similarity metrics, could accelerate this process. In this study, we established the article relationship using MEDLINE element similarities and visualized the article network with the Force Atlas layout. We also analyzed the article networks with graph diameter, closeness centrality, and module classes. The results revealed the distribution of articles and found that included articles tended to aggregate together in some module classes, providing further evidence of the existence of strong relationships among included articles. This approach can be utilized to facilitate the articles selection process through early identification of these dominant module classes. We are optimistic that the use of article network visualization can help better SR work prioritization.

Characteristics of relationship itself play an important role in determining well-being of individuals who participate in the relationship. We used efficacy expectations mutually shared between close friends or romantic partners as a characteristic of relationship and investigated its impact on their life satisfaction. In Study 1, we conducted a cross-sectional study among 137 pairs of close same-sex friends to test whether the efficacy expectations shared between friends are associated with levels of life satisfaction. In Study 2, we conducted a longitudinal study among 114 heterosexual romantic couples to test predictive validity of the efficacy expectations shared between couples predict levels of life satisfaction 2 month later. In both studies we found a consistent result that as degrees of the efficacy expectations shared between individuals in a relationship increased, the degree of their life satisfaction also increased. Underlying mechanisms that explain how characteristics of relationship itself increase life satisfaction are discussed. PMID:27437946

Previous research has demonstrated how the Internet can foster emotional support and provide a 'private' space for discussing sensitive issues. Whilst the family has been located as a primary source of support, empirical research on the dynamics of close personal relationships in chronic illness experience remains a challenge. To explore the role of family relationships in supporting self-care and the nature of social support exchanged within an online self-management training course. Qualitative thematic and narrative analysis of online discussion boards. Postings for 218 participants, divided between 11 groups were included for a course section that focused on 'difficult emotions'. Participants exchanged a high degree of emotional support and revealed much about their 'real life' relationships. The latter highlighted the complexities of managing illness within family contexts alongside additional pressures of daily life such as caring commitments and work roles. The private interactive space created within the course allowed insights into the dynamics of family life associated with illness management that are challenging to research. Simultaneously, collective support was developed amongst this group of predominantly working women. The article points to the implications for such interventions and associated evaluative research beyond this selective group.

The work environment and its effect on engagement and retention of nuclear medicine technologists: differences between public and private sector workers.

The retention of Australian nuclear medicine technologists (NMTs) is poor with the future workforce size in question. As a consequence, the primary aim of this study was to determine Australian NMTs' level of work engagement and the factors influencing this to identify the issues surrounding retention. The job demands resource model assumes that each job has its own demands and resources and the balance between these can influence the level of work engagement. Lower levels of work engagement are predictive of an intention to leave. Work engagement levels can be measured using the Utrecht work engagement scale. This study used the Utrecht Work Engagement Scale in a self-report questionnaire with additional open-ended and closed-ended items designed to evaluate satisfying job characteristics. Members of the professional body in specific geographical locations of Australia were invited to participate. A 49.6% response rate was achieved (n=201); of these, 164 were practicing NMTs. Public sector workers had significantly lower total mean scores (P=0.05) on the Utrecht Work Engagement Scale and the subscale of dedication (P=0.005) compared with private NMTs. Seven of the 14 job satisfaction closed-ended items were statistically significantly lower for public NMTs: the level of decision making; feelings of importance with the tasks performed; feedback on tasks and roles; and relationships with physicians, staff and the organization. To improve the retention of NMTs, changes in the job resources and demands are needed. Advanced practice roles may improve retention by enhancing the job resources.

The role of child maltreatment and attachment style in adolescent relationship violence.

PubMed

Wekerle, C; Wolfe, D A

1998-01-01

Utilizing attachment theory as a basis for conceptualizing close relationships among adolescents, this study investigated two important relationship risk factors (child maltreatment, and adolescent self-perceived insecure attachment style) as predictors of "offender" and "victim" experiences in youth relationships. In addition to considering the influence of these risk factors, we further considered their interaction in predicting conflict in close relationships. Of interest was the extent to which attachment styles may function as a moderator of the relationship between childhood abuse and current abuse in teen close relationships. High school students (N = 321) in grades 9 and 10 completed questionnaires tapping their histories of maltreatment, currently viewed styles of attachment, and conflict in close relationships over the past 6 months. Maltreatment alone emerged as the most consistent predictor, accounting for 13-18% of the variance in male's physically, sexually, and verbally abusive behaviors; in contrast, it was not highly predictive of female's abusive behaviors. Maltreatment was predictive of victimization experiences for both males and females. Attachment style did not substantially add to the prediction of relationship conflict beyond maltreatment; however, avoidant attachment style emerged repeatedly as a significant predictor of female abusiveness and victimization. Attachment self-ratings were found to function as a moderator of child maltreatment in predicting primarily male coercive behavior towards a relationship partner as well as predicting male's experience of coercion from a partner. Thus, the presence of childhood maltreatment and adolescent self-perceived insecure attachment style applies predominantly to male youth. The implication of these gender differences for understanding relationship violence is discussed.

Systemic inflammation is thought to be a biological mediator between social relationship quality and premature mortality. Empirical work has yielded mixed support for an association of social relationship variables with systemic inflammation, perhaps due to methodological limitations. To date, research in this literature has focused on global perceptions of social relationships, with limited attention to the covariance of characteristics of daily social interactions with inflammation. Here, we examine whether daily interactions, as assessed by ecological momentary assessment (EMA), associate with peripheral markers of inflammation among midlife and older adults. Global social support and integration were measured using the Interpersonal Support Evaluation List (ISEL) and the Social Network Index (SNI), respectively, in older adults from the Pittsburgh Healthy Heart Project (PHHP), and in middle-aged adults from the Adult Health and Behavior Project-II (AHAB-II). Using time-sampled EMA, we assessed the proportion of the day spent in positive and negative social interactions. Systemic markers of inflammation were interleukin (IL)-6 and C-reactive protein (CRP). Global measures of support and integration did not associate with inflammation in either sample. In older adults, relative frequency of total positive interactions, those with close others (i.e. spouse, friends, family), and those with coworkers predicted lower concentrations of IL-6 in fully adjusted models, accounting for age, sex, race, education, BMI, smoking and alcohol. In middle-aged adults, relative frequency of positive interactions with close others was also inversely associated with IL-6 level and relative frequency of negative marital interactions was unexpectedly inversely associated with CRP level. Characteristics of daily social interactions among midlife and older adults associate with markers of systemic inflammation that are known to predict risk for cardiovascular disease. Ambulatory measures may better capture health-relevant social processes in daily life than retrospective, global self-report measures. Published by Elsevier Inc.

Two members of the Baikal sig family, a lake sig (Coregonus lavaretus baicalensis Dybovsky) and omul (C. autumnalis migratorius Georgi), are close relatives that diverged from the same ancestor 10-20 thousand years ago. In this work, we studied genomic polymorphism of these two fish species. The method of subtraction hybridization (SH) did not reveal the presence of extended sequences in the sig genome and their absence in the omul genome. All the fragments found by SH corresponded to polymorphous noncoding genome regions varying in mononucleotide substitutions and short deletions. Many of them are mapped close to genes of the immune system and have regions identical to the Tc-1-like transposons abundant among fish, whose transcription activity may affect the expression of adjacent genes. Thus, we showed for the first time that genetic differences between Baikal sig family members are extremely small and cannot be revealed by the SH method. This is another endorsement of the hypothesis on the close relationship between Baikal sig and omul and their evolutionarily recent divergence from a common ancestor.

The role of stress on close relationships and marital satisfaction.

Stress is a concept that has received increased attention in marital research during the last decade, showing that it plays an important role in understanding the quality and stability of close relationships. Evidence suggests that stress is a threat to marital satisfaction and its longevity. Research has been based upon theoretical models of stress in close relationships, specifically family stress models [e.g., Hill, R. (1958). Generic features of families under stress. Social Casework, 39, 139-150.; McCubbin, H. I., & Patterson, J. M. (1983). Family transitions: Adaptation to stress. In H. I. McCubbin & C. R.

In T. Revenson, K. Kayser, & G. Bodenmann (Eds.), Couples coping with stress: Emerging perspectives on dyadic coping (pp.33-50). American Psychological Association: Washington, D.C.]. In this review we: (1) examine the various theoretical models of stress, (2) analyze and summarize the typologies relating to stress models (internal versus external, major versus minor, acute versus chronic), and (3) summarize findings from stress research in couples that has practical significance and may inspire clinical work. Future directions in research and clincial significance are suggested.

Professional relationships between general practitioners and pharmacists in health centres.

The inclusion of pharmacies in health centres has created opportunities for general practitioners to become better acquainted with the potential contribution of pharmacists to health care. A qualitative study has been made to explore the extent to which this potential has been realized. Ten health centres with an integral pharmacy were selected, one from each of the regional health authorities in England which had at least one such health centre. Interviews were conducted with 13 general practitioners and 10 pharmacists working in the health centres. Nine general practitioners working in health centres without pharmacies and 10 community pharmacists were also interviewed. General practitioners' attitudes towards health centre pharmacists appeared to differ markedly from the attitudes of colleagues working in relative isolation from pharmacists. It appears that general practitioners working closely with the pharmacist develop a collaborative approach to health care. PMID:2271280

Terahertz and infrared Smith-Purcell radiation from Babinet metasurfaces: Loss and efficiency

When a charged particle moves close and parallel to the surface of a Babinet metasurface composed of metallic C -aperture resonators, strong electromagnetic radiation arises at resonant frequency. Here we systematically study the Smith-Purcell effects in Babinet metasurfaces with different periods. By tuning the period, the resonant (or working) frequency of the metasurface can vary from GHz to THz and infrared ranges. It is found that for working frequencies lower than 10 GHz, the ratio of absorption loss to input power is about 3.7%. Although the loss ratio increases with increasing working frequency, it remains as low as 11% (29%) at a working frequency of 10 THz (224 THz). Due to the existence of loss, a nonlinear relationship is also found between resonant frequency and the reciprocal of period. Our results suggest that Babinet metasurfaces could be a good candidate for fabricating efficient, compact THz and infrared free-electron light sources.

Research is clear that power differentials between women and men shape women's human immunodeficiency virus (HIV) risks; however, little research has attempted to examine power differentials within same-sex male (SSM) couples and whether these influence sexual risk outcomes. To produce the first quantitative scale that measures power in SSM relationships, the current work was a Phase 1 qualitative study that sought to understand domains of relationship power and how power operated in the relationship among 48 Black, White, and interracial (Black-White) SSM couples recruited from San Francisco and New York. Interview domains were focused on definitions of power and perceptions of how power operated in the relationship. Findings revealed that couples described power in three key ways: as power exerted over a partner through decision-making dominance and relationship control; as power to accomplish goals through personal agency; and as couple-level power. In addition, men described ways that decision-making dominance and relationship control could be enacted in the relationship-through structural resources, emotional and sexual influence, and gender norm expectations. We discuss the implications of these findings for sexual risks and HIV care and treatment with SSM couples that are focused on closing gaps in power.

Social cognition is an important determinant of functional impairment in schizophrenia, but its relationship with the prefrontal functional abnormalities associated with the condition is still unclear. The present study aimed to explore the relationship between social cognition and prefrontal function in patients with schizophrenia using 52-channel near-infrared spectroscopy (NIRS). Twenty-six patients with schizophrenia and 26 age-, gender-, and intelligence quotient-matched healthy controls (HCs) participated in the study. Hemodynamic responses in the prefrontal and superior temporal cortical regions were assessed during a working memory task using NIRS. Social cognition was assessed using the Social Cognition Screening Questionnaire (SCSQ). The observed hemodynamic responses were significantly reduced in the lateral prefrontal cortex (PFC), the frontopolar cortex, and temporal regions in subjects with schizophrenia compared to HCs. Additionally, lateral PFC hemodynamic responses assessed during the working memory task demonstrated a strong positive correlation with the SCSQ theory of mind (ToM) subscale score even after controlling for working memory performance. These results suggest that ToM integrity is closely related to lateral PFC functional abnormalities found in patients with schizophrenia. In addition, this study provides evidence to suggest that NIRS could be used to identify biomarkers of social cognition function in subjects with schizophrenia.

Tobacco, Alcohol, and Drug Use of People With Mood and Anxiety Disorders: Differential Impact of Family and Friends.

Substance use among people with mood and anxiety disorders is highly prevalent. The literature suggests that substance use among people with mood and anxiety disorders is linked to social relational factors, yet it has rarely been the case that studies explicitly examine the differential impact of family and friends. This study investigated the association among family relationships, friendships, and substance use among people with mood and anxiety disorders. Using the National Survey of American Life, structural equation modeling tested the unique effects of family relationships and friendships on tobacco, alcohol, and drug use (n = 1,076). The quality of family relationships was assessed using 12 items on the frequency of contact with family, received help from family, closeness in feeling toward family, and emotional support from family. The quality of friendships was assessed using four items on the frequency of contact with friends, received and given help, and closeness in feeling toward friends. Substance use was measured using self-reported use of tobacco, alcohol, and drugs. Findings indicated that family relationships (β = -.101, p = .031) and friendships (β = .142, p = .004) were associated with drug use among people with mood and anxiety disorders, controlling for gender, age, race, education level, employment status, income, and family substance use history. Yet, family relationships and friendships were not significantly associated with tobacco and alcohol use. People with mood and anxiety disorders who had better family relationships were less likely to use drugs, while those who had better friendships were more likely to use drugs. Practitioners should be attentive to the differential impact of family and friends when working with people with mood and anxiety disorders to reduce the risk of drug use. Family interventions promoting and maintaining quality relationships with family will be helpful. However, friendships may facilitate drug use of people with mood and anxiety disorders. Practitioners should be cognizant of the potential risks of friendship networks for people with mood and anxiety disorders.

Individuals use a range of interpersonal emotion regulation strategies to influence the feelings of others, e.g., friends, family members, romantic partners, work colleagues. But little is known about whether people vary their strategy use across these different relational contexts. We characterize and measure this variability as "spin," i.e., the extent of dispersion in a person's interpersonal emotion regulation strategy use across different relationships, and focus on two key questions. First, is spin adaptive or maladaptive with regard to personal well-being and relationship quality? Second, do personality traits that are considered important for interpersonal functioning (i.e., empathy, attachment style) predict spin? The data used in this study is drawn from a large online survey. A key contribution of this study is to reveal that people who varied the type of strategies they used across relationships (i.e., those with high spin) had lower positive mood, higher emotional exhaustion, and less close relationships. A further key contribution is to show that spin was associated with low empathic concern and perspective taking and high anxious attachment style. High variability in interpersonal emotion regulation strategies across relationships therefore appears to be maladaptive both personally and socially.

Does individualism bring happiness? Negative effects of individualism on interpersonal relationships and happiness.

We examined the negative effects of individualism in an East Asian culture. Although individualistic systems decrease interpersonal relationships through competition, individualistic values have prevailed in European American cultures. One reason is because individuals could overcome negativity by actively constructing interpersonal relationships. In contrast, people in East Asian cultures do not have such strategies to overcome the negative impact of individualistic systems, leading to decreased well-being. To test this hypothesis, we investigated the relationship between individualistic values, number of close friends, and subjective well-being (SWB). Study 1 indicated that individualistic values were negatively related with the number of close friends and SWB for Japanese college students but not for American college students. Moreover, Study 2 showed that even in an individualistic workplace in Japan, individualistic values were negatively related with the number of close friends and SWB. We discuss how cultural change toward increasing individualism might affect interpersonal relationships and well-being.

Theodor Billroth and Johannes Brahms shared a decades long personal friendship. The music-loving Billroth influenced the work of the famous composer and in turn Brahms also left traces within Billroth's lifetime achievements. To shed light on the close relationship of medicine and music, this manuscript describes both Billroth's life and surgical career as they were influenced and stimulated by his close friendship to Brahms.Theodor Billroth and Johannes Brahms first met in 1865 in Zurich, Switzerland. After Billroth accepted the chair of surgery at the University of Vienna in 1867, Brahms moved to Vienna in 1869. During the following years, Billroth analyzed most of Brahms' compositions prior to publication. Similar to his effective way of teaching medical students and assistants, Billroth stimulated Brahms to publish many of his later compositions. Brahms on the other hand supported Billroth in writing his essay"Who is musical?". Furthermore, music helped Billroth to cope with the demanding working life of a surgeon.Music and surgery share both structural and emotional analogies. While both professions require meticulous techniques, personal interaction is a prerequisite for success. "Science and art scoop from the same well."

The disorder-specific psychological impairment in complex PTSD: A flawed working model for restoration of trust.

PubMed

Laddis, Andreas

2018-03-22

This article methodically gathers concepts and findings from related disciplines to propose that there is a fundamental, disorder-specific psychological impairment, which defines Complex Posttraumatic Stress Disorder (PTSD) as etiologically different from simple PTSD. This impairment is a flawed working model for restoration of trust when one partner fears betrayal. This working model is legacy of childhood relationships with manipulative caretakers who kept the child powerless to test the trustworthiness of their reasons to break promises and to fail the child's expectations. Manipulative caretakers invert the respective roles and responsibilities for restoration of trust, which constitutes perversion of intimacy. This article describes how that fundamental flaw becomes the cause of patients' disorder, by episodically rendering them powerless to ascertain a perception of grave betrayal as true or false in later relationships. Repeated failure with experiments for certainty about others' love explains the characteristic personality traits and beliefs of persons with Complex PTSD, i.e., cynicism about the world's benevolence, self-derogation and sense of a foreshortened future. This article closes with reference to a study that investigated the efficacy of a crisis intervention designed to remediate this fundamental impairment.

Dog Breed Differences in Visual Communication with Humans

2016-01-01

Domestic dogs (Canis familiaris) have developed a close relationship with humans through the process of domestication. In human-dog interactions, eye contact is a key element of relationship initiation and maintenance. Previous studies have suggested that canine ability to produce human-directed communicative signals is influenced by domestication history, from wolves to dogs, as well as by recent breed selection for particular working purposes. To test the genetic basis for such abilities in purebred dogs, we examined gazing behavior towards humans using two types of behavioral experiments: the ‘visual contact task’ and the ‘unsolvable task’. A total of 125 dogs participated in the study. Based on the genetic relatedness among breeds subjects were classified into five breed groups: Ancient, Herding, Hunting, Retriever-Mastiff and Working). We found that it took longer time for Ancient breeds to make an eye-contact with humans, and that they gazed at humans for shorter periods of time than any other breed group in the unsolvable situation. Our findings suggest that spontaneous gaze behavior towards humans is associated with genetic similarity to wolves rather than with recent selective pressure to create particular working breeds.

Relationships between social competence, psychopathology and work performance and their predictive value for vocational rehabilitation of schizophrenic outpatients.

Earlier studies suggest that social competence has a higher predictive value for vocational outcome than psychopathology. These studies, however, show methodological shortcomings, including the fact that the instruments used for assessing social competence, psychopathology and work performance are strongly interrelated. The present study, involving a population of 34 chronically schizophrenic outpatients enrolled in a vocational rehabilitation program, was conducted in order to determine: (1) how closely the Role Play Test, the Positive and Negative Syndrome Scale and the Work Behavior Assessment Scale are related to each other; and (2) whether social competence is a better predictor of work performance and outcome of vocational rehabilitation than psychopathology. Factor analysis has revealed that the instruments are interrelated, mainly in the dimensions of negative symptoms, social relationships, non-verbal measures of social competence and conceptual disorganization. In backward regression analyses, psychopathological indicators proved to be the best predictors of work performance both cross-sectionally as well as in the longterm course. In the traditional two-syndrome model of schizophrenic psychopathology only negative symptoms were left in the regression model. In a four-dimension model the disorder of relating and the conceptual disorganization dimension were the best predictors. Differences between disorder of relating and social competence, assessed by the Role Play Test, are discussed here as well as the implications of this study for rehabilitation.

Background The purpose of this study was to examine the relationship nursing personal and workplace system factors (work disability) and work ability index scores in Ontario, Canada. Methods A total of 111 registered nurses were randomly selected from the total number of registered nurses on staff in the labor, delivery, recovery, and postpartum areas of four northeastern Ontario hospitals. Using a stratified random design approach, 51 participants were randomly selected in four northeastern Ontario cities. Results A total of 51 (45.9% response rate) online questionnaires were returned and another 60 (54.1% response rate) were completed using the paper format. The obstetric workforce in northeastern Ontario was predominately female (94.6%) with a mean age of 41.9 (standard deviation = 10.2). In the personal systems model, three variables: marital status (p = 0.025), respondent ethnicity (p = 0.026), and mean number of patients per shift (p = 0.049) were significantly contributed to the variance in work ability scores. In the workplace system model, job and career satisfaction (p = 0.026) had a positive influence on work ability scores, while work absenteeism (p = 0.023) demonstrated an inverse relationship with work ability scores. In the combined model, all the predictors were significantly related to work ability scores. Conclusion Work ability is closely related to job and career satisfaction, and perceived control at work among obstetric nursing. In order to improve work ability, nurses need to work in environments that support them and allow them to be engaged in the decision-making processes. PMID:26929842

Ground water-surface-water relationships were studied in five morphological segments in the Bonaparte Creek basin, Washington during 1979 and 1980. In one segment, kettle lakes were found to be closely associated with the ground-water system. In the other four segments, a close relationship was found between streamflow and ground water. It was concluded that additional ground-water development would adversely affect lake levels and streamflow, thereby reducing surface-water resources already closed to further appropriation. The ground-water divide between the Bonaparte and Sanpoil basins was 6 miles southeast of where it was estimated to be. (USGS)

2015-11-01

Consciousness and working memory are two widely studied cognitive phenomena. Although they have been closely tied on a theoretical and neural level, empirical work that investigates their relation is largely lacking. In this study, the relationship between visual consciousness and different working memory components is investigated by using a dual-task paradigm. More specifically, while participants were performing a visual detection task to measure their visual awareness threshold, they had to concurrently perform either an executive or visuospatial working memory task. We hypothesized that visual consciousness would be hindered depending on the type and the size of the load in working memory. Results showed that maintaining visuospatial content in working memory hinders visual awareness, irrespective of the amount of information maintained. By contrast, the detection threshold was progressively affected under increasing executive load. Interestingly, increasing executive load had a generic effect on detection speed, calling into question whether its obstructing effect is specific to the visual awareness threshold. Together, these results indicate that visual consciousness depends differently on executive and visuospatial working memory.

Food allergy is a common immunologic disease that includes potentially fatal reactions. It impacts considerably on patients' social life including close interpersonal relationships. Attachment theory provides a theoretic framework to evaluate the quality of close interpersonal relationships in chronic disorders. Attachment insecurity, mainly characterized by attachment avoidance, has been found in a variety of health conditions, but still needs to be investigated in food allergy. The study aimed to investigate attachment, as attitude to close interpersonal relationships, among food-allergic young patients, compared to healthy controls. This is a cross-sectional study involving patients suffering from IgE-mediated food allergy sequentially recruited and matched to healthy controls for age and gender. The Attachment Style Questionnaire (ASQ) was used to assess five factors and two attachment dimensions (Anxiety-Avoidance). Associations with anaphylaxis and adrenaline prescription were explored among patients. 174 participants were assessed (female=45%; mean age=17.51; SD=4.26). Food-allergic patients reported significantly higher levels of Discomfort with Closeness (P<.05), Relationships as Secondary (P<.05) and Attachment Avoidance (P<.0001) compared to controls. Clinicians should be aware of implications of insecure attachment for health and illness. They should support patients in limiting social impairment finding a balance between safety and psychologic well-being. © 2017 EAACI and John Wiley and Sons A/S.

Belgium, France, the Netherlands, and the United Kingdom occupy a middle ground and are less specifically defined. Furthermore, "the statistical map shows a strong relationship which manifests itself in two opposite ways. On the one hand, it shows the link between a traditional family structure and a weak integration of women in the working population (Spain, Ireland), and, on the other hand, it shows a close link between a divided family and the fact women have a paying job, often just part time (Sweden, Denmark)."

1999-08-01

This work incorporates concepts from the behavioral confirmation tradition, self tradition, and interdependence tradition to identify an interpersonal process termed the Michelangelo phenomenon. The Michelangelo phenomenon describes the means by which the self is shaped by a close partner's perceptions and behavior. Specifically, self movement toward the ideal self is described as a product of partner affirmation, or the degree to which a partner's perceptions of the self and behavior toward the self are congruent with the self's ideal. The results of 4 studies revealed strong associations between perceived partner affirmation and self movement toward the ideal self, using a variety of participant populations and measurement methods. In addition, perceived partner affirmation--particularly perceived partner behavioral affirmation--was strongly associated with quality of couple functioning and stability in ongoing relationships.

Measuring spiritual well-being among clergy is particularly important given the high relevance of God to their lives, and yet its measurement is prone to problems such as ceiling effects and conflating religious behaviors with spiritual well-being. To create a measure of closeness to God for Christian clergy, we tested survey items at two time points with 1,513 United Methodist Church clergy. The confirmatory factor analysis indicated support for two, six-item factors: Presence and Power of God in Daily Life, and Presence and Power of God in Ministry. The data supported the predictive and concurrent validity of the two factors and evidenced high reliabilities without ceiling effects. This Clergy Spiritual Well-being Scale may be useful to elucidate the relationship among dimensions of health and well-being in clergy populations.

Peer relationships undergo dramatic shifts in form and function during adolescence, at the same time the incidence of socially evaluative fears sharply rises. Despite well-established links between social anxiety and broader interpersonal functioning, there is a dearth of research evaluating the impact of social anxiety on functioning in close relationships during this developmental stage. The present study examines the impact of social anxiety on functioning in close friendships and romantic relationships during adolescence. From a developmental psychopathology perspective, it was expected that social anxiety would influence functioning (quality, length, satisfaction) in romantic relationships through its influence on functioning in same- and other-sex friendships. Participants included 314 adolescents (60.5% female, 14-19 years of age) with a prior or current history of romantic relationship involvement. Structural equation modeling was used to test a mediation model positing an indirect pathway from social anxiety to romantic relationship functioning through functioning in close same- and other-sex friendships. Given known gender differences in social anxiety and relationship functioning, gender also was explored as a potential moderator. Results supported the hypothesized indirect pathway whereby social anxiety was associated with impairment in same-sex friendships; functioning in same-sex friendships was associated with functioning in other-sex friendships, which was associated, in turn, with functioning in romantic relationships. While the hypothesized indirect pathway was significant among both boys and girls, there was greater continuity of functioning between same- and other-sex friendships for girls. These findings highlight the importance of examining the multiple downstream effects of social anxiety on perceived social functioning in adolescence, and suggest that continuity may exist for maladaptive patterns of socialization, particularly across developmentally salient close relationships.

Scorpions: A Presentation

Scorpions, at least the species of the family Buthidæ whose venoms are better known, appear as animals that have evolved very little over time. The composition of their venoms is relatively simple as most toxins have a common structural motif that is found in other venoms from primitive species. Moreover, all the scorpion venom toxins principally act on membrane ionic channels of excitable cells. The results of recent works lead to the conclusion that in scorpions there is a close relationship between venomous function and innate immune function both remarkably efficient. PMID:25133517

Peer acceptance protects global self-esteem from negative effects of low closeness to parents during adolescence and early adulthood.

Having a distant relationship with parents seems to increase the risk of developing a more negative global self-esteem. This article describes a longitudinal study of 1,090 Norwegian adolescents from the age of 13-23 (54 % males) that explored whether peer acceptance can act as a moderator and protect global self-esteem against the negative effects of experiencing low closeness in relationships with parents. A quadratic latent growth curve for global self-esteem with closeness to parents and peer acceptance as time-varying covariates was modeled, taking partial measurement invariance in global self-esteem into account. Peer acceptance was found to have a general protective effect on global self-esteem for all adolescents. In addition, at most ages, peer acceptance was found to have a protective-stabilizing effect on the relationship between closeness to parents and global self-esteem. This indicates that peer acceptance can be an especially valuable source of global self-esteem when closeness to parents is low.

The relationship between the faecal egg count and the worm burden of the gastrointestinal tract of sheep was examined. Close relationships were found in strongyles, Trichostrongylidae (other than Nematodirus spp.), Nematodirus spp., Strongyloides papillosus, Chabertiidae and Trichuris spp.. Due to high percentage of false negative diagnosis from faecal examination, this relationship was in Nematodirus spp. and Trichuris spp. not as close as in the other nematodes. However, the results support the high diagnostic value of quantitative faecal examinations in sheep.

Blue colour preference in honeybees distracts visual attention for learning closed shapes.

PubMed

Morawetz, Linde; Svoboda, Alexander; Spaethe, Johannes; Dyer, Adrian G

2013-10-01

Spatial vision is an important cue for how honeybees (Apis mellifera) find flowers, and previous work has suggested that spatial learning in free-flying bees is exclusively mediated by achromatic input to the green photoreceptor channel. However, some data suggested that bees may be able to use alternative channels for shape processing, and recent work shows conditioning type and training length can significantly influence bee learning and cue use. We thus tested the honeybees' ability to discriminate between two closed shapes considering either absolute or differential conditioning, and using eight stimuli differing in their spectral characteristics. Consistent with previous work, green contrast enabled reliable shape learning for both types of conditioning, but surprisingly, we found that bees trained with appetitive-aversive differential conditioning could additionally use colour and/or UV contrast to enable shape discrimination. Interestingly, we found that a high blue contrast initially interferes with bee shape learning, probably due to the bees innate preference for blue colours, but with increasing experience bees can learn a variety of spectral and/or colour cues to facilitate spatial learning. Thus, the relationship between bee pollinators and the spatial and spectral cues that they use to find rewarding flowers appears to be a more rich visual environment than previously thought.

Navigating the interdependence dilemma: Attachment goals and the use of communal norms with potential close others.

PubMed

Bartz, Jennifer A; Lydon, John E

2006-07-01

Four studies investigated attachment in the context of new relationship development. Anxiously attached individuals overwhelmingly used communal norms and avoided using exchange norms when interacting with a potential close other; however, when a potential close other used communal norms, anxious individuals experienced increased interpersonal anxiety. Anxious individuals also used discrete communal behaviors to diagnose relationship potential. By contrast, secure individuals were more comfortable in potential communal situations. Moreover, implicit thoughts about closeness were associated with improved performance on a mental concentration task for secure individuals, whereas implicit closeness thoughts were associated with poorer performance for anxious individuals. Finally, avoidant individuals disliked the potential close other when the other used communal norms and downplayed relational motives for the other's communal behavior.

Relationships and the social brain: integrating psychological and evolutionary perspectives.

PubMed

Sutcliffe, Alistair; Dunbar, Robin; Binder, Jens; Arrow, Holly

2012-05-01

Psychological studies of relationships tend to focus on specific types of close personal relationships (romantic, parent-offspring, friendship) and examine characteristics of both the individuals and the dyad. This paper looks more broadly at the wider range of relationships that constitute an individual's personal social world. Recent work on the composition of personal social networks suggests that they consist of a series of layers that differ in the quality and quantity of relationships involved. Each layer increases relationship numbers by an approximate multiple of 3 (5-15-50-150) but decreasing levels of intimacy (strong, medium, and weak ties) and frequency of interaction. To account for these regularities, we draw on both social and evolutionary psychology to argue that relationships at different layers serve different functions and have different cost-benefit profiles. At each layer, the benefits are asymptotic but the costs of maintaining a relationship at that level (most obviously, the time that has to be invested in servicing it) are roughly linear with the number of relationships. The trade-off between costs and benefits at a given level, and across the different types of demands and resources typical of different levels, gives rise to a distribution of social effort that generates and maintains a hierarchy of layered sets of relationships within social networks. We suggest that, psychologically, these trade-offs are related to the level of trust in a relationship, and that this is itself a function of the time invested in the relationship. ©2011 The British Psychological Society.

Adolescents’ Emotional Reactivity across Relationship Contexts

Cook, Emily C.; Buehler, Cheryl; Blair, Bethany L.

2012-01-01

Adolescents’ emotional reactivity in family, close friendships, and romantic relationships was examined in a community-based sample of 416 two-parent families. Six waves of annual data were analyzed using structural equation modeling. Emotional reactivity to interparental conflict during early adolescence was associated prospectively with adolescents’ reactivity to conflict in friendships and romantic relationships during middle adolescence. Close friendship reactivity partially explained the prospective association between reactivity to interparental conflict and romantic relationship reactivity. The association between perceived emotional reactivity and relationship conflict was stronger for girls than boys. Results have important developmental implications regarding adolescents’ emotional reactivity across salient interpersonal contexts during adolescence. PMID:22545839

This article reports findings from a participative and qualitative study conducted with children who had experienced domestic violence, focusing on their perspectives on their relationships with their mothers. Three focus groups and 46 individual interviews were conducted with children to gather their experiences. The research findings demonstrate that women's and children's victimizations are inextricably linked, and that domestic violence affects mother-child relationships. They also show that, despite the challenges and difficulties, children generally consider their mothers as very significant individuals in their lives, and have close relationships with them. The findings also reveal a dynamic of mutual protectiveness.

Depression frequently involves disrupted inter-personal relationships, while treatment with serotonergic anti-depressants can interfere with libido and sexual function. However, little is known about how serotonin activity influences appraisals of intimate partnerships. Learning more could help to specify how serotonergic mechanisms mediate social isolation in psychiatric illness. Forty-four healthy heterosexual adults, currently in romantic relationships, received 8 days treatment with the selective serotonin re-uptake inhibitor citalopram (N = 21; 10 male) or placebo (N = 23; 12 male). Participants viewed photographs of unknown, heterosexual couples and made a series of judgements about their relationships. Participants also indicated the importance of relationship features in their own close partnerships, and close partnerships generally. Citalopram reduced the rated quality of couples’ physical relationships and the importance attributed to physical and intimate aspects of participants’ own relationships. In contrast, citalopram also enhanced the evaluated worth of mutual trust in relationships. Amongst males, citalopram was associated with judgements of reduced turbulence and bickering in others’ relationships, and increased male dominance. These data constitute preliminary evidence that enhancing serotonin activity modulates cognitions about sexual activity as part of a re-appraisal of sources of value within close intimate relationships, enhancing the judged importance of longer-term benefits of trust and shared experiences.

Lehna, Carlee

2010-01-01

The purpose of this research project was to understand, primarily from the sibling perspective, the effect of a child's major burn injury on his or her sibling. A mixed method qualitative dominant design was implemented using the life story method for the qualitative portion. Additionally, the Sibling Relationship Questionnaire -Revised (SRQ-R) was used as a structured interview guide and for calculating scoring data to explore sibling relationship factors of warmth/closeness, rivalry, conflict, and relative status/power. Participants from 22 family cases (one or multiple family members) and 40 individuals were interviewed. To capture impact on the family over time, interviews began a minimum of two years post-burn. The central thematic pattern for the sibling relationship in families having a child with a major burn injury was that of normalization. Two components of normalization were described: areas of normalization and the process of adjustment. Areas of normalization were found in play and other activities, in school and work, and in family relations with siblings. The process of adjustment was varied and often gradual, involved school and work re-entry, and in some instances, seemed to change life perspective. Clinical implications in providing family-centered care can focus on promoting normalization by assessing and supporting siblings who may only be occasionally seen in the hospital or clinic.

none declared. Employees' job satisfaction and commitment depends upon the leadership style of managers. This study clarifies further the relationships between leadership behaviors of managers and two employees' work-related attitudes-job satisfaction and organizational at public hospitals in Iran. A better understanding of these issues and their relationships can pinpoint better strategies for recruiting, promotion, and training of future hospital managers and employees, particularly in Iran but perhaps in other societies as well. This cross-sectional study was conducted using self-administered questionnaires distributed among 814 hospital employees and managers through a stratified random sampling. The dominant leadership style of hospital managers was participative style. Hospital employees were moderately satisfied with their jobs and committed to their organization. Salaries, benefits, promotion, contingent rewards, interpersonal relationships and working conditions were the best predictors of job satisfaction among hospitals employees. Leadership, job satisfaction and commitment were closely interrelated. The leadership behavior of managers explained 28% and 20% of the variations in job satisfaction and organizational commitment respectively. This study clarifies the causal relations of job satisfaction and commitment, and highlights the crucial role of leadership in employees' job satisfaction and commitment. Nevertheless, participative management is not always a good leadership style. Managers should select the best leadership style according to the organizational culture and employees' organizational maturity.

The association between varicella (chickenpox) and group A streptococcus infections in historical perspective

Coleman, Stephen

2016-01-01

Objectives: The aim of the research is to investigate the historical relationship between varicella and Streptococcus pyogenes infections. In the past few decades, varicella has been identified as a risk factor for invasive group A streptococcus infections. The question is whether this relationship also existed between varicella and scarlet fever in the historical era. Methods: The analysis begins with a search of historical medical reports on the relationship between varicella and scarlet fever epidemics in the late 19th and early 20th century, as well as in more recent empirical studies. Correlations and cross-correlations between varicella and scarlet fever are analyzed using weekly public health case reports from 1924 to 1932 for Boston, Chicago, New York City, and Philadelphia. Regression models are used to estimate the relationship between varicella and scarlet fever after controlling for seasonal forcing. Results: Historical records give limited support for a causal relationship between varicella and scarlet fever but indicate that these diseases often occurred close in time to each other. Likewise, statistical analysis shows that varicella and scarlet fever epidemics are closely aligned with each other, and varicella has a strong relationship with scarlet fever. The relationship is stronger than reported in any previous research on the two diseases. Conclusion: The close correspondence of the two diseases likely depends on multiple factors, including seasonal forcing, a causal relationship, and co-infections. The results raise questions about whether this close relationship might have had a synergistic effect or a role in the evolution of S. pyogenes from the virulent, high incidence epidemics of the 19th century to the relatively benign scarlet fever of the 1950s.

The formation of romantic relationships and friendships in adolescence is a defining milestone in the progression toward social maturity. Thus, examining adolescents' friendship and romantic experiences serves a vital role in understanding their psychological adjustment. The main purposes of the current study were to examine (a) whether romantic involvement, romantic security, and friendship closeness were independently predictive of late adolescents' depression and loneliness, and (b) whether friendship closeness would moderate the negative effects of adolescents' lower degrees of romantic involvement and romantic security on depression and loneliness. Data came from 12th grade adolescents (N = 110, 53 females) as well as their parents and a same-sex best friend. Adolescents reported on their romantic involvement, romantic security, and psychological distress. Parent reports of adolescents' depressive symptoms and friend reports of friendship closeness were also included. Higher degrees of romantic involvement and friendship closeness were related to lower degrees of loneliness. Higher degrees of romantic security were related to lower degrees of depression and loneliness. The effect of romantic involvement on depression and loneliness was moderated by friendship closeness. Also, the effect of romantic security on loneliness was moderated by friendship closeness. Future research should focus on the interactive roles that friendships and romantic relationships play in the emergence of psychopathology during adolescence. © The Author(s) 2015.

New Look at Social Support: A Theoretical Perspective on Thriving through Relationships

Feeney, Brooke C.; Collins, Nancy L.

2017-01-01

Close and caring relationships are undeniably linked to health and well-being at all stages in the lifespan. Yet the specific pathways through which close relationships promote optimal well-being are not well understood. In this article, we present a model of thriving through relationships to provide a theoretical foundation for identifying the specific interpersonal processes that underlie the effects of close relationships on thriving. This model highlights two life contexts through which people may potentially thrive (coping successfully with life’s adversities and actively pursuing life opportunities for growth and development), it proposes two relational support functions that are fundamental to the experience of thriving in each life context, and it identifies mediators through which relational support is likely to have long-term effects on thriving. This perspective highlights the need for researchers to take a new look at social support by conceptualizing it as an interpersonal process with a focus on thriving. PMID:25125368

Does individualism bring happiness? Negative effects of individualism on interpersonal relationships and happiness

PubMed Central

Ogihara, Yuji; Uchida, Yukiko

2014-01-01

We examined the negative effects of individualism in an East Asian culture. Although individualistic systems decrease interpersonal relationships through competition, individualistic values have prevailed in European American cultures. One reason is because individuals could overcome negativity by actively constructing interpersonal relationships. In contrast, people in East Asian cultures do not have such strategies to overcome the negative impact of individualistic systems, leading to decreased well-being. To test this hypothesis, we investigated the relationship between individualistic values, number of close friends, and subjective well-being (SWB). Study 1 indicated that individualistic values were negatively related with the number of close friends and SWB for Japanese college students but not for American college students. Moreover, Study 2 showed that even in an individualistic workplace in Japan, individualistic values were negatively related with the number of close friends and SWB. We discuss how cultural change toward increasing individualism might affect interpersonal relationships and well-being. PMID:24634663

This study argues for the necessity of applying offline contexts to social networking site research and the importance of distinguishing the relationship types of users' counterparts when studying Facebook users' behaviors. In an attempt to examine the relationship among users' behaviors, their counterparts' relationship types, and the users' perceived acquaintanceships after using Facebook, this study first investigated users' frequently used tools when interacting with different types of friends. Users tended to use less time- and effort-consuming and less privacy-concerned tools with newly acquired friends. This study further examined users' behaviors in terms of their closeness and intimacy and their perceived acquaintanceships toward four different types of friends. The study found that users gained more perceived acquaintanceships from less close friends with whom users have more frequent interaction but less intimate behaviors. As for closer friends, users tended to use more intimate activities to interact with them. However, these activities did not necessarily occur more frequently than the activities they employed with their less close friends. It was found that perceived acquaintanceships with closer friends were significantly lower than those with less close friends. This implies that Facebook is a mechanism for new friends, rather than close friends, to become more acquainted.

Friends with benefits (FWB) relationships are formed by an integration of friendship and sexual intimacy, typically without the explicit commitments characteristic of an exclusive romantic relationship. The majority of these relationships do not transition into committed romantic relationships, raising questions about what happens to the relationship after the FWB ends. In a sample of 119 men and 189 women university students, with a median age of 19 years and the majority identified as Caucasian (63.6 %), we assessed relationship adjustment, feelings of deception, perception of the FWB relationship and friendship, social connectedness, psychological distress, and loneliness. Results demonstrated that the majority of FWB relationships continued as friendships after the sexual intimacy ceased and that about 50 % of the participants reported feeling as close or closer to their FWB partner. Those who did not remain friends were more likely to report that their FWB relationship was more sex- than friendship-based; they also reported higher levels of feeling deceived by their FWB partner and higher levels of loneliness and psychological distress, but lower levels of mutual social connectedness. Higher levels of feeling deceived were related to feeling less close to the post-FWB friend; also, more sex-based FWB relationships were likely to result in post-FWB friendships that were either more or less close (as opposed to unchanged). FWB relationships, especially those that include more attention to friendship based intimacy, do not appear to negatively impact the quality of the friendship after the "with benefits" ends.

Using a feminist postmodern perspective and the sensitizing concept of split loyalties from Contextual Theory, the primary purpose of this qualitative study was to develop a better understanding of how adult female adoptees from closed adoptions negotiate relationships with their adoptive and biological mothers post-reunion. We conducted semi-structured individual interviews with nine adult female adoptees, ages 28-52, who were adopted prior to the age of two. Six were Caucasian, three were African American, and the average age at reunion was 29. Grounded theory techniques were used to code the qualitative data, in particular the constant comparative method of analysis. Four main categories emerged: (a) Negotiating Mother-Daughter Relationships, (b) Relating to Mothers Equitably, (c) Loyalty, and (d) Adoptees' Emotional Needs. Our findings suggest the adoptive mother-daughter relationship has a salient effect on adoptees' relationships with biological mothers post-reunion. Loyalty to the adoptive mother seems to influence the evolving relationship and closeness displayed toward the birth mother. Adult female adoptees from closed adoptions described struggling with managing their two mother-daughter relationships and need clinical help addressing their own emotional needs. © 2012 American Association for Marriage and Family Therapy.

Substance use has long been associated with close relationship distress. Although the direction of influence for this association has not been established, it has often been assumed that substance use is the causal agent and that close relationship distress is the effect. But research seeking to establish temporal precedence in this link has produced mixed findings. Further, theoretical models of substance use and close relationship processes present the plausibility of the inverse pathway-that insecure close relationships may serve as a vulnerability factor for the development of later substance problems. The current review applies an attachment-theoretical framework to the association between close social bonds and substance use and substance-related problems. Targeting longitudinal studies of attachment and substance use, we examined 665 effect sizes drawn from 34 samples (total N = 56,721) spanning time frames ranging from 1 month to 20 years (M = 3.8 years). Results revealed a significant prospective correlation between earlier attachment and later substance use (r = -.11, 95% CI [-.14, -0.08]). Further, cross-lagged coefficients were calculated which parsed auto-regressive effects, indicating that lower attachment security temporally preceded increases in substance use (r = -.05, 95% CI [-.06, -.04]). Analyses further indicated that the pathway from earlier attachment to later substance use was significantly stronger than that from earlier substance use to later attachment. Results also revealed several moderators of the attachment-substance use link. These findings suggest that insecure attachment may be a vulnerability factor for substance use, and indicate close relationship quality as a promising line of inquiry in research on substance use disorder risk.

Henriksen, Roger Ekeberg; Torsheim, Torbjørn; Thuen, Frode

2014-01-01

Objective Social Baseline Theory (SBT) proposes that close relationships aid in metabolic resource management and that individuals without significant relationships may experience more demands on their own neural metabolic resources on a daily basis when solving problems, remaining vigilant against potential threats and regulating emotional responses. This study tests a hypothesised consequence derived from SBT: relative social isolation leads to increased levels of sugar intake. Methods Based on cross-sectional, self-reported data from the Norwegian Mother and Child Cohort Study (N = 90 084), information on social integration and the consumption of both sugar-sweetened and artificially sweetened sodas and juices was obtained from a large number of women in early pregnancy. Multiple regression analyses were conducted to assess whether loneliness, marital status, relationship satisfaction, advice from others than partner, and cohesion at work is associated with consumption of sodas and juices. Results Perceived loneliness was associated with elevated intake of all sugary beverages, while relationship satisfaction was negatively associated with all sugary beverages. Being married or cohabitating, having supportive friends, and having a sense of togetherness at work were associated with lower intake of two out of three sugar-containing beverages. These associations were significant, even after controlling for factors such as body mass index, weight related self-image, depression, physical activity, educational level, age and income. In comparison, a statistically significant relationship emerged between relationship satisfaction and artificially sweetened cola. No other predictor variables were significantly associated with any type of artificially sweetened beverage. Conclusions This study indicates that loneliness and social integration influence the level of consumption of sugary beverages. The results support the hypothesis derived from the Social Baseline Theory that relative social isolation leads to increased levels of sugar intake. PMID:25105408

With or Without You? Contextualizing the Impact of Romantic Relationship Breakup on Crime Among Serious Adolescent Offenders.

PubMed

Larson, Matthew; Sweeten, Gary; Piquero, Alex R

2016-01-01

The decline and delay of marriage has prolonged adolescence and the transition to adulthood, and consequently fostered greater romantic relationship fluidity during a stage of the life course that is pivotal for both development and offending. Yet, despite a growing literature of the consequences of romantic relationships breakup, little is known about its connection with crime, especially among youth enmeshed in the criminal justice system. This article addresses this gap by examining the effects of relationship breakup on crime among justice-involved youth-a key policy-relevant group. We refer to data from the Pathways to Desistance Study, a longitudinal study of 1354 (14% female) adjudicated youth from the juvenile and adult court systems in Phoenix and Philadelphia, to assess the nature and complexity of this association. In general, our results support prior evidence of breakup's criminogenic influence. Specifically, they suggest that relationship breakup's effect on crime is particularly acute among this at-risk sample, contingent upon post-breakup relationship transitions, and more pronounced for relationships that involve cohabitation. Our results also extend prior work by demonstrating that breakup is attenuated by changes in psychosocial characteristics and peer associations/exposure. We close with a discussion of our findings, their policy implications, and what they mean for research on relationships and crime among serious adolescent offenders moving forward.

This paper presents our latest work on comprehensive modeling of process-structure-property relationships for additive manufacturing (AM) materials, including using data-mining techniques to close the cycle of design-predict-optimize. To illustrate the processstructure relationship, the multi-scale multi-physics process modeling starts from the micro-scale to establish a mechanistic heat source model, to the meso-scale models of individual powder particle evolution, and finally to the macro-scale model to simulate the fabrication process of a complex product. To link structure and properties, a highefficiency mechanistic model, self-consistent clustering analyses, is developed to capture a variety of material response. The model incorporates factors such as voids, phase composition, inclusions, and grain structures, which are the differentiating features of AM metals. Furthermore, we propose data-mining as an effective solution for novel rapid design and optimization, which is motivated by the numerous influencing factors in the AM process. We believe this paper will provide a roadmap to advance AM fundamental understanding and guide the monitoring and advanced diagnostics of AM processing.

Some evidence suggests that close friends may be knowledgeable of youth's psychological adjustment. However, friends are understudied as reporters of adjustment. The current study examines associations between self- and friend-reports of internalizing and externalizing adjustment in a community sample of fifth-, eighth-, and eleventh-grade youth. The study extends prior work by considering the degree to which friends' reports of youth adjustment are accurate (i.e., predicted by youths' actual adjustment) versus biased (i.e., predicted by the friend reporters' own adjustment). Findings indicated stronger bias effects than accuracy effects, but the accuracy effects were significant for both internalizing and externalizing adjustment. Additionally, friends who perceived their relationships as high in positive quality, friends in relationships high in disclosure, and girls perceived youths' internalizing symptoms most accurately. Knowledge of externalizing adjustment was not influenced by gender, grade, relationship quality, or self-disclosure. Findings suggest that friends could play an important role in prevention efforts.

To explore the impact of meteorological factors on the outbreak of bacillary dysentery, so as to provide suggestions for disease prevention. Based on the Chinese medicine theory of Yunqi, the descriptive statistics, single-factor correlation analysis and back-propagation artificial neural net-work were conducted using data on five basic meteorological factors and data on incidence of bacillary dysentery in Beijing, China, for the period 1970-2004. The incidence of bacillary dysentery showed significant positive correlation relationship with the precipitation, relative humidity, vapor pressure, and temperature, respectively. The incidence of bacillary dysentery showed a negatively correlated relationship with the wind speed and the change trend of average wind speed. The results of medical-meteorological forecast model showed a relatively high accuracy rate. There is a close relationship between the meteorological factors and the incidence of bacillary dysentery, but the contributions of which to the onset of bacillary dysentery are different to each other.

Several studies have reported a functional relationship between spectral power within the theta-band of the EEG (theta-power) and memory load while processing visual or semantic information. We investigated theta power during the processing of different complex haptic stimuli using a delayed recall design. The haptic explorations consisted of palpating the structure of twelve sunken reliefs with closed eyes. Subjects had to reproduce each relief by drawing it 10 s after the end of the exploration. The relationship between mean theta power and mean exploration time was analysed using a regression model. A linear relationship was found between the exploration time and theta power over fronto-central regions (Fp1, Fp2, F3, F7, F8, Fz, C3) directly before the recall of the relief. This result is interpreted in favour of the hypothesis that fronto-central theta power of the EEG correlates with the load of working memory independent of stimulus modality.

Potential negative effects of perspective-taking efforts in the context of close relationships: increased bias and reduced satisfaction.

PubMed

Vorauer, Jacquie D; Sucharyna, Tamara A

2013-01-01

Three experiments demonstrated that trying to appreciate a close other's unique point of view (imagine-other perspective taking) increases the extent to which individuals overestimate their own transparency to the close other, that is, how many of their values, preferences, traits, and feelings are readily apparent to him or her. Trying to be objective and pay careful attention to cues from a close other, which inhibits perspective taking, instead had the opposite effect. Mediation analyses suggested that increased focus on the self as an object of evaluation contributed to the positive effect of imagine-other perspective taking on perceived transparency, and decreased focus on the self as an object of evaluation contributed to the negative effect of trying to be objective on these judgments. These effects on perceived transparency had important implications for relationship well-being: Enhanced perceived transparency of negative feelings prompted by imagine-other perspective taking during a back-and-forth exchange with a romantic partner led to systematic discrepancies between individuals' own and their partner's experience of the exchange and reduced relationship satisfaction; trying to be objective instead reduced perceived transparency and thereby increased satisfaction. Notably, initial closeness with another person enhanced rather than tempered the egocentric effects of perspective taking. Taken together, these results suggest that positive motivations to nurture a close relationship and be sensitive to a loved one might sometimes be better channeled toward paying closer attention to his or her behavior than toward perspective taking.

Authentic leadership: a new theory for nursing or back to basics?

PubMed

Wong, Carol; Cummings, Greta

2009-01-01

Authentic leadership is an emerging theoretical model purported to focus on the root component of effective leadership. The purpose of this paper is to describe the relevance of authentic leadership to the advancement of nursing leadership practice and research and address the question of whether this is a new theory for leadership or an old one in new packaging. The paper outlines the origins and key elements of the model, assesses the theoretical, conceptual and measurement issues associated with authentic leadership and compares it with other leadership theories frequently reported in the nursing literature. The emerging authentic leadership theory holds promise for explaining the underlying processes by which authentic leaders and followers influence work outcomes and organizational performance. Construct validity of authentic leadership has preliminary documentation and a few studies have shown positive relationships between authenticity and trust. Furthermore, the clarity of the authenticity construct and comprehensiveness of the overall theoretical framework provide a fruitful base for future research examining the relationship between authentic leadership and the creation of healthier work environments. A clear focus on the relational aspects of leadership, the foundational moral/ethical component, a potential linkage of positive psychological capital to work engagement and the emphasis on leader and follower development in the authentic leadership framework are closely aligned to current and future nursing leadership practice and research priorities for the creation of sustainable changes in nursing work environments.

Using Spatial Multiple Regression to Identify Intrinsic Connectivity Networks Involved in Working Memory Performance

Gordon, Evan M.; Stollstorff, Melanie; Vaidya, Chandan J.

2012-01-01

Many researchers have noted that the functional architecture of the human brain is relatively invariant during task performance and the resting state. Indeed, intrinsic connectivity networks (ICNs) revealed by resting-state functional connectivity analyses are spatially similar to regions activated during cognitive tasks. This suggests that patterns of task-related activation in individual subjects may result from the engagement of one or more of these ICNs; however, this has not been tested. We used a novel analysis, spatial multiple regression, to test whether the patterns of activation during an N-back working memory task could be well described by a linear combination of ICNs delineated using Independent Components Analysis at rest. We found that across subjects, the cingulo-opercular Set Maintenance ICN, as well as right and left Frontoparietal Control ICNs, were reliably activated during working memory, while Default Mode and Visual ICNs were reliably deactivated. Further, involvement of Set Maintenance, Frontoparietal Control, and Dorsal Attention ICNs was sensitive to varying working memory load. Finally, the degree of left Frontoparietal Control network activation predicted response speed, while activation in both left Frontoparietal Control and Dorsal Attention networks predicted task accuracy. These results suggest that a close relationship between resting-state networks and task-evoked activation is functionally relevant for behavior, and that spatial multiple regression analysis is a suitable method for revealing that relationship.

Health Effects of Shift Work

LaDou, Joseph

1982-01-01

More than 13.5 million American workers, close to 20 percent of the work force, are assigned to evening or night shifts. In some industries such as automobile, petrochemical and textile manufacturing the proportion of shift workers is greater than 50 percent. As the popularity of shift work and other “alternative work schedules” grows, concern is increasing over the disturbance created in the lives of workers and their families by these economically and socially useful innovations. Twenty percent of workers are unable to tolerate shift work. Daily physiologic variations termed circadian rhythms are interactive and require a high degree of phase relationship to produce subjective feelings of wellbeing. Disturbance of these activities, circadian desynchronization, whether from passage over time zones or from shift rotation, results in health effects such as disturbance of the quantity and quality of sleep, disturbance of gastrointestinal and other organ system activities, and aggravation of diseases such as diabetes mellitus, epilepsy and thyrotoxicosis. Worker selection can reduce the number of health problems resulting from shift work. The periodic examination of shift workers is recommended. PMID:6962577

Adult Children of Gay Fathers: Parent-Child Relationship Quality and Mental Health.

According to family systems theory, parent-child relationships are an important aspect of individual wellbeing. This study explored associations among parental disclosure, parent-child relationships, and wellbeing among 84 adult children with gay fathers. We explored associations between the adult children's wellbeing and the children's ages at sexual orientation disclosure, geographic distance, relationship quality, and closeness with their fathers. We found that when parental disclosure had occurred earlier in the adult child's life, participants reported feeling closer to fathers in adulthood. Those who reported closer relationships with their fathers reported greater wellbeing. Using a stepwise regression, we found that adult children's reports of closeness with fathers were the best predictors of adult children's wellbeing.

Ambivalent Sexism in Close Relationships: (Hostile) Power and (Benevolent) Romance Shape Relationship Ideals

2013-01-01

Gender-based structural power and heterosexual dependency produce ambivalent gender ideologies, with hostility and benevolence separately shaping close-relationship ideals. The relative importance of romanticized benevolent versus more overtly power-based hostile sexism, however, may be culturally dependent. Testing this, northeast US (N=311) and central Chinese (N=290) undergraduates rated prescriptions and proscriptions (ideals) for partners and completed Ambivalent Sexism and Ambivalence toward Men Inventories (ideologies). Multiple regressions analyses conducted on group-specific relationship ideals revealed that benevolent ideologies predicted partner ideals, in both countries, especially for US culture’s romance-oriented relationships. Hostile attitudes predicted men’s ideals, both American and Chinese, suggesting both societies’ dominant-partner advantage. PMID:23914004

To determine the level of knowledge of the prevention of ventilator-associated pneumonia guidelines of nurses working in three intensive care units (ICU) in 3 university hospitals in a Spanish region, and evaluate the relationship between this level of knowledge and years worked in the ICU. A descriptive, prospective, cross-sectional, multicentre study was conducted using a validated and reliable questionnaire, made up by 9 questions with closed answers drawn from the EVIDENCE study. A total of 98 questionnaires were collected from ICU nurses of the three university hospitals (A, B, and C) from January to April 2014. The sample from hospital A responded the most, in contrast with the sample from hospital B, which was the one with the less participation. The Pearson correlation was calculated in order to determine the relationship between nurse years worked in ICU and level of knowledge. Hospital A obtained in the best mean score in the questionnaire, 6.33 (SD 1.4) points, followed by hospital C with 6.21 (SD 1.4), and finally, the hospital B with 6.06 (SD 1.5) points. A p=.08 was obtained on relating years worked with the level of knowledge. The results showed a high level of knowledge compared other studies. There was a tendency between the years worked in the unit and the level of knowledge in ventilator-associated pneumonia prevention. Copyright © 2016 Elsevier España, S.L.U. y SEEIUC.

2008-02-01

Musculoskeletal strain and other symptoms are common in visual display unit (VDU) work. Psychosocial factors are closely related to the outcome and experience of musculoskeletal strain. The user-computer relationship from the viewpoint of the quality of perceived competence in computer use was assessed as a psychosocial stress indicator. It was assumed that the perceived competence in computer use moderates the experience of musculoskeletal strain and the success of the ergonomics intervention. The participants (n = 124, female 58%, male 42%) worked with VDU for more than 4 h per week. They took part in an ergonomics intervention and were allocated into three groups: intensive; education; and reference group. Musculoskeletal strain, the level of ergonomics of the workstation assessed by the experts in ergonomics and amount of VDU work were estimated at the baseline and at the 10-month follow-up. Age, gender and the perceived competence in computer use were assessed at the baseline. The perceived competence in computer use predicted strain in the upper and the lower part of the body at the follow-up. The interaction effect shows that the intensive ergonomics intervention procedure was the most effective among participants with high perceived competence. The interpretation of the results was that an anxiety-provoking and stressful user-computer relationship prevented the participants from being motivated and from learning in the ergonomics intervention. In the intervention it is important to increase the computer competence along with the improvements of physical workstation and work organization.

First law of black hole mechanics as a condition for stationarity

NASA Astrophysics Data System (ADS)

McCormick, Stephen

2014-11-01

In earlier work, we provided a Hilbert manifold structure for the phase space for the Einstein-Yang-Mills equations, and used this to prove a condition for initial data to be stationary [S. McCormick, Adv. Theor. Math. Phys. 18, 799 (2014)]. Here we use the same phase space to consider the evolution of initial data exterior to some closed 2-surface boundary, and establish a condition for stationarity in this case. It is shown that the differential relationship given in the first law of black hole mechanics is exactly the condition required for the initial data to be stationary; this was first argued nonrigorously by Sudarsky and Wald [Phys. Rev. D 46, 1453 (1992)]. Furthermore, we give evidence to suggest that if this differential relationship holds then the boundary surface is the bifurcation surface of a bifurcate Killing horizon.

Depression frequently involves disrupted inter-personal relationships, while treatment with serotonergic anti-depressants can interfere with libido and sexual function. However, little is known about how serotonin activity influences appraisals of intimate partnerships. Learning more could help to specify how serotonergic mechanisms mediate social isolation in psychiatric illness. Forty-four healthy heterosexual adults, currently in romantic relationships, received 8 days treatment with the selective serotonin re-uptake inhibitor citalopram (N = 21; 10 male) or placebo (N = 23; 12 male). Participants viewed photographs of unknown, heterosexual couples and made a series of judgements about their relationships. Participants also indicated the importance of relationship features in their own close partnerships, and close partnerships generally. Citalopram reduced the rated quality of couples' physical relationships and the importance attributed to physical and intimate aspects of participants' own relationships. In contrast, citalopram also enhanced the evaluated worth of mutual trust in relationships. Amongst males, citalopram was associated with judgements of reduced turbulence and bickering in others' relationships, and increased male dominance. These data constitute preliminary evidence that enhancing serotonin activity modulates cognitions about sexual activity as part of a re-appraisal of sources of value within close intimate relationships, enhancing the judged importance of longer-term benefits of trust and shared experiences. © The Author (2013).

Dishion, T J; Andrews, D W; Crosby, L

1995-02-01

This study examines the close friendships of early adolescent boys in relation to antisocial behavior. 186 13-14-year-old boys and their close friends were interviewed, assessed at school, and videotaped in a problem-solving task. Similarity was observed between the demographic characteristics and antisocial behavior of the boys and their close friends. There was a tendency for the close friends of antisocial boys to live within the same neighborhood block and to have met in unstructured, unsupervised activities. Direct observations of interactions with close friends revealed a reliable correlation between antisocial behavior, directives, and negative reciprocity. Positive interactions within the friendship were uncorrelated with antisocial behavior and relationship quality. Implications of these findings for clinical and developmental theory are discussed.

The majority of care for people with type 2 diabetes occurs in general practice, however when insulin initiation is required it often does not occur in this setting or in a timely manner and this may have implications for the development of complications. Increased insulin initiation in general practice is an important goal given the increasing prevalence of type 2 diabetes and a relative shortage of specialists. Coordination between primary and secondary care, and between medical and nursing personnel, may be important in achieving this. Relational coordination theory identifies key concepts that underpin effective interprofessional work: communication which is problem solving, timely, accurate and frequent and relationships between professional roles which are characterized by shared goals, shared knowledge and mutual respect. This study explores roles and relationships between health professionals involved in insulin initiation in order to gain an understanding of factors which may impact on this task being carried out in the general practice setting. 21 general practitioners, practice nurses, diabetes nurse educators and physicians were purposively sampled to participate in a semi-structured interview. Transcripts of the interviews were analysed using framework analysis. There were four closely interlinked themes identified which impacted on how health professionals worked together to initiate people with type 2 diabetes on insulin: 1. Ambiguous roles; 2. Uncertain competency and capacity; 3. Varying relationships and communication; and 4. Developing trust and respect. This study has shown that insulin initiation is generally recognised as acceptable in general practice. The role of the DNE and practice nurse in this space and improved communication and relationships between health professionals across organisations and levels of care are factors which need to be addressed to support this clinical work. Relational coordination provides a useful framework for exploring these issues.

Relational-interdependent self-construal as a predictor of relationship quality: the mediating roles of one's own behaviors and perceptions of the fulfillment of friendship functions.

PubMed

Morry, Marian M; Kito, Mie

2009-06-01

Relational-interdependent self-construal (RISC) is the tendency to think of oneself in terms of relationships with close others, and it influences relationship cognitions (e.g., closeness, commitment, perceived similarity). The authors expected individuals high in RISC to report more relationship supportive behaviors (RSB; e.g., higher levels of trust, more intimate disclosures), experience greater fulfillment of friendship functions (FrFu; e.g., help, emotional security, stimulating companionship), and report higher relationship quality than individuals low in RISC. The authors also hypothesized that RSB would mediate the RISC-friendship function and the RISC-relationship quality relations and that FrFu would mediate the relation between RSB and relationship quality. Structural equation modeling supported the authors' hypotheses. These effects did not differ across friendship type (same or cross sex). The authors discuss the importance of self-construal for relationship research.

Embedding Climate Services

Shafer, M.; Boone, M.; Keim, B. D.

2015-12-01

With the rapidly-increasing number of climate services providers, the landscape for putting climate into practice is getting both easier to access and more confusing. Each provider serves a different clientele, and in so doing draws more stakeholder organizations into the sphere of those using climate information in decision-making. The challenge has been in connecting these new stakeholders with expertise that may reside within a different provider organization. To help close the gap, the Southern Climate Impacts Planning Program (SCIPP; http://www.southernclimate.org), a NOAA RISA Team, initiated a summer internship program, where students with expertise in meteorology or climatology would work for an organization more closely aligned with another climate services provider network. The format was patterned after the successful NSF-funded Research Experience for Undergraduates (REU) program at the National Weather Center, where students are selected from undergraduate programs across the nation to spend a summer conducting research under a scientific mentor. The SCIPP initiative flipped this model, instead sending students to organizations with operational needs for climate information to work under their mentorship in partnership with SCIPP scientists. Over the past two summers, SCIPP has recruited students to work at landscape-based (Gulf Coast Joint Venture and National Wetlands Research Center) and community-based (Tulsa Partners) organizations. Students worked alongside the organizations' staff on a daily basis and were supported through periodic calls with the SCIPP team to help identify appropriate datasets and work through methodological issues. This presentation will discuss how these relationships were created, the expertise of each of the organizations involved, and outcomes from the projects.

Practice Based Small Group Learning (PBSGL) is an established learning resource for primary care clinicians in Scotland and is used by one-third of general practitioners (GPs). Scottish Government and UK professional bodies have called for GPs and pharmacists to work more closely together to improve care. To gain GPs' and pharmacists' perceptions and experiences of learning together in an inter-professional PBSGL pilot. Qualitative research methods involving established GP PBSGL groups in NHS Scotland recruiting one or two pharmacists to join them. A grounded theory method was used. GPs were interviewed in focus groups by a fellow GP, and pharmacists were interviewed individually by two researchers, neither being a GP or a pharmacist. Interviews were audio-recorded, transcribed and analysed using grounded theory methods. Data saturation was achieved and confirmed. Three themes were identified: GPs' and pharmacists' perceptions and experiences of inter-professional learning; Inter-professional relationships and team-working; Group identity and purpose of existing GP groups. Pharmacists were welcomed into GP groups and both professions valued inter-professional PBSGL learning. Participants learned from each other and both professions gained a wider perspective of the NHS and of each others' roles in the organisation. Inter-professional relationships, communication and team-working were strengthened and professionals regarded each other as peers and friends.

Equivalence of the Floquet-Magnus and Fer Expansions to Investigate the Dynamics of a Spin System in the Three-Level System.

PubMed

Mananga, Eugene Stephane

2017-08-17

In this work, we investigated the orders to which the Floquet-Magnus expansion (FME) and Fer expansion (FE) are equivalent or different for the three-level system. Specifically, we performed the third-order calculations of both approaches based on elegant integrations formalism. We present an important close relationship between the Floquet-Magnus and Fer expansions. As the propagator from the FME takes the form of the evolution operator, which removes the constraint of a stroboscopic observation, we appreciated the effects of time-evolution under Hamiltonians with different orders separately. Our work unifies and generalizes existing results of Floquet-Magnus and Fer approaches and delivers illustrations of novel springs that boost previous applications that are based on the classical information. Due to the lack of an unequivocal relationship between the FME and FE, some disagreements between the results produced by these theories will be found, especially in NMR experiments. Our results can find applications in the optimization of NMR spectroscopy, quantum computation, quantum optical control, and coherence in optics and might bear new awareness in fundamental perusals of quantum spin dynamics. This work is an important theoretical and numerical contribution in the general field of spin dynamics.

Happy employees lead to loyal patients. Survey of nurses and patients shows a strong link between employee satisfaction and patient loyalty.

PubMed

Atkins, P M; Marshall, B S; Javalgi, R G

1996-01-01

A strong relationship exists between employee satisfaction and patients' perceptions of the quality of their care, measured in terms of their intent to return and to recommend the hospital to others. Employee dissatisfaction can negatively affect quality of care and have an adverse effect on patient loyalty and, thus hospital profitability. Therefore, health care marketers should regularly measure employee satisfaction as one way to monitor service quality. Health care marketers must work more closely with their human-resource departments to understand and influence employees' work environment and maintain a high level of job satisfaction. Marketers also should place an increased emphasis on both employee and patient perceptions of satisfaction when developing internal and external strategic marketing plans and formulating future research.

The seventeenth century witnessed the replacement of an Aristotelian worldview by a mechanical one. It also witnessed the beginnings of significant experimental enquiry. Alerted by the fact that the methods involved in the latter, but not in the former, resemble those employed in later science, I argue the historical case that the emergence of the mechanical worldview and the emergence of science were not closely related and that it was the latter that was to develop into science as we have come to know it. The details are explored in the context of the philosophical and experimental work of Robert Boyle and the relationship between them. Copyright © 2015 Elsevier Ltd. All rights reserved.

Sunken costs and desired plans: examining different types of investments in close relationships.

PubMed

Goodfriend, Wind; Agnew, Christopher R

2008-12-01

Although the concept of investments in romantic relationships has featured prominently in close relationships research, there have been no empirical analyses of different types of investments and their possible differential predictive power regarding relationship state or fate. With data from five independent samples, the authors offer and examine investments that differ in terms of their timing (past vs. planned) and materiality (tangible vs. intangible). Cross-sectional and longitudinal tests of hypotheses regarding these investment types provide evidence for the utility of considering specific types of investments in predicting a variety of important relationship factors, including commitment, stability, and the impact of breakup on relationship partners. Intangible investments and planned investments were found to be particularly robust predictors of key relational states and outcomes.

Ionic Liquids and Relative Process Design

NASA Astrophysics Data System (ADS)

Zhang, S.; Lu, X.; Zhang, Y.; Zhou, Q.; Sun, J.; Han, L.; Yue, G.; Liu, X.; Cheng, W.; Li, S.

Ionic liquids have gained increasing attention in recent years due to their significant advantages, not only as alternative solvents but also as new materials and catalysts. Until now, most research work on ionic liquids has been at the laboratory or pilot scale. In view of the multifarious applications of ionic liquids, more new knowledge is needed and more systematic work on ionic liquids should be carried out deeply and broadly in order to meet the future needs of process design. For example, knowledge of the physicochemical properties is indispensable for the design of new ionic liquids and for the development of novel processes. The synthesis and application of ionic liquids are fundamental parts of engineering science, and the toxicity and environmental assessment of ionic liquids is critical importance for their large scale applications, especially for process design. These research aspects are closely correlated to the industrial applications of ionic liquids and to sustainable processes. However, material process design in the industrial applications of ionic liquids has hardly been implemented. Therefore, this chapter reviews several essential issues that are closely related to process design, such as the synthesis, structure-property relationships, important applications, and toxicity of ionic liquids.

The aim of this study was to evaluate the relationship between the cisternal segment of the oculomotor nerve and the posterior cerebral artery and its branches. The oculomotor nerve and the posterior cerebral artery of 15 cadaver brains (30 hemispheres) were examined using a surgical microscope. The dorsal portion of the cisternal segment of the oculomotor nerve had a close relationship with the P(1) and P(2) segments of the posterior cerebral artery in 100% of cases, the thalamoperforating arteries in 97%, the collicular arteries in 97%, the short circumferential arteries in 33% and the posterior medial choroidal arteries in 20%. The proximal portion of the nerve had a close relationship with the P(1) segment of the posterior cerebral artery, the thalamoperforating arteries, the collicular arteries and the short circumferential arteries, whereas the distal portion had a close relationship with the P(2) segment of the posterior cerebral artery and the posterior medial choroidal arteries. The oculomotor nerve was perforated by various arteries in different portions. These arteries were the thalamoperforating arteries in 10% of the hemispheres, the collicular arteries in 16% and the short circumferential arteries in 11%. It can be concluded that the dorsal portion of the cisternal segment of the oculomotor nerve has a close relationship with the branches arising from the P(1) and P(2) segments of the posterior cerebral artery. These arteries supply the cisternal segment of the oculomotor nerve.

The Psychology of Close Relationships: Fourteen Core Principles.

PubMed

Finkel, Eli J; Simpson, Jeffry A; Eastwick, Paul W

2017-01-03

Relationship science is a theory-rich discipline, but there have been no attempts to articulate the broader themes or principles that cut across the theories themselves. We have sought to fill that void by reviewing the psychological literature on close relationships, particularly romantic relationships, to extract its core principles. This review reveals 14 principles, which collectively address four central questions: (a) What is a relationship? (b) How do relationships operate? (c) What tendencies do people bring to their relationships? (d) How does the context affect relationships? The 14 principles paint a cohesive and unified picture of romantic relationships that reflects a strong and maturing discipline. However, the principles afford few of the sorts of conflicting predictions that can be especially helpful in fostering novel theory development. We conclude that relationship science is likely to benefit from simultaneous pushes toward both greater integration across theories (to reduce redundancy) and greater emphasis on the circumstances under which existing (or not-yet-developed) principles conflict with one another.

Going that extra mile: individuals travel further to maintain face-to-face contact with highly related kin than with less related kin.

The theory of inclusive fitness has transformed our understanding of cooperation and altruism. However, the proximate psychological underpinnings of altruism are less well understood, and it has been argued that emotional closeness mediates the relationship between genetic relatedness and altruism. In this study, we use a real-life costly behaviour (travel time) to dissociate the effects of genetic relatedness from emotional closeness. Participants travelled further to see more closely related kin, as compared to more distantly related kin. For distantly related kin, the level of emotional closeness mediated this relationship--when emotional closeness was controlled for, there was no effect of genetic relatedness on travel time. However, participants were willing to travel further to visit parents, children and siblings as compared to more distantly related kin, even when emotional closeness was controlled for. This suggests that the mediating effect of emotional closeness on altruism varies with levels of genetic relatedness.

[Alcoholism and reformism in restoration Spain].

Campos Marin, R

1993-01-01

The number of medical pamphlets dealing with the problem of alcoholism, especially in the working classes, increased during the Restoration. At the same time, the State began to show concern about establishing social policies directed at improving the life-style of the proletariat and at their moralization. This study is attempting to establish the relationship that existed between these two phenomens via the debate about the social causes of alcoholism. The controversy about the closing of taverns on Sundays, developed between the Partido Socialista Obrero Español (Spanish Socialist Party) and certain sectors of the bourgeoisie synthesize the problem to be addressed.

Improving the quality of contraceptive counseling is one strategy to prevent unintended pregnancy. We identify aspects of relational and task-oriented communication in family planning care that can assist providers in meeting their patients’ needs. Approaches to optimizing women's experiences of contraceptive counseling include working to develop a close, trusting relationship with patients and using a shared decision-making approach that focuses on eliciting and responding to patient preferences. Providing counseling about side effects and using strategies to promote contraceptive continuation and adherence can also help optimize women's use of contraception. PMID:25264697

We review the xanthine oxidase (XO) family of pyranopterin molybdenum enzymes with a specific emphasis on electronic structure contributions to reactivity. In addition to xanthine and aldehyde oxidoreductases, which catalyze the two-electron oxidation of aromatic heterocycles and aldehyde substrates, this mini-review highlights recent work on the closely related carbon monoxide dehydrogenase (CODH) that catalyzes the oxidation of CO using a unique Mo-Cu heterobimetallic active site. A primary focus of this mini-review relates to how spectroscopy and computational methods have been used to develop an understanding of critical relationships between geometric structure, electronic structure, and catalytic function.

The capacity for romantic intimacy: exploring the contribution of best friend and marital and parental relationships.

PubMed

Scharf, M; Mayseless, O

2001-06-01

This study examined, in a longitudinal design, the contributions of three different relationships, namely marital, parent-child and best friend, to the capacity for intimacy in romantic relationships of Israeli male adolescents, as well as the mediating role of socio-emotional capacities. Eighty-four 17-year-old adolescents and their parents filled out questionnaires concerning the quality of these relational contexts. Four years later the Intimacy Status Interview was administered to the adolescents at the conclusion of their mandatory military service to examine closeness, separateness, and commitment within their romantic relationships. Results showed that all relational contexts were related to capacity for intimacy (directly or indirectly), with higher relational qualities associated with better capability for intimacy. The marital relationship was associated with intimacy through its effect on the parent-child relationships. The effects of the parent-child relationships on the capacity for intimacy were mediated through the adolescents' socio-emotional capabilities. The contribution of the parent-adolescent relationships to the capacity for closeness and commitment was further mediated through relationships with the best friend, whereas the contribution to the capacity for separateness was not. A substantial number of our participants showed high capability for intimacy although in the military service context the circumstances for the development of intimacy were quite limited and non-optimal. Exploration of the separateness and closeness facets of intimacy in romantic relationships in the two sexes and in other contexts is recommended.

Measuring the impact of major life events upon happiness.

PubMed

Ballas, Dimitris; Dorling, Danny

2007-12-01

In recent years there have been numerous attempts to define and measure happiness in various contexts and pertaining to a wide range of disciplines, ranging from neuroscience and psychology to philosophy, economics and social policy. This article builds on recent work by economists who attempt to estimate happiness regressions using large random samples of individuals in order to calculate monetary 'compensating amounts' for different life 'events'. We estimate happiness regressions using the 'major life event' and 'happiness' data from the British Household Panel Survey. The data and methods used in this article suggest that in contrast to living states such as 'being married', it is more events such as 'starting a new relationship' that have the highest positive effect on happiness. This is closely followed by 'employment-related gains' (in contrast to employment status). Also, women who become pregnant on average report higher than average levels of subjective happiness (in contrast to 'being a parent'). Other events that appear to be associated with happiness according to our analysis include 'personal education-related events' (e.g. starting a new course, graduating from University, passing exams) and 'finance/house related events' (e.g. buying a new house). On the other hand, the event that has the highest negative impact upon happiness according to our analysis is 'the end of my relationship' closely followed by 'death of a parent'. Adverse health events pertaining to the parents of the respondents also have a high negative coefficient and so does an employment-related loss. The analysis presented in this article suggests that what matters the most in people's lives in Britain is to have good dynamic interpersonal relationships and to be respected at work with that respect being constantly renewed. These 'goods' are as much reflected through dynamic events as static situations. Relationships at work appear to be of a similar order of importance to those at home. Other factors that contribute to higher than average levels of subjective happiness, at least at a superficial level, include delaying death and keeping illness at bay, having babies, buying homes and cars and passing exams. The analysis presented here also suggests that people should not expect too much from their holidays and wider families. The findings presented in this article may help us to understand a little better the propensity for groups to be more or less happy and may help us to begin to better understand the importance of the dynamics of social context-the context in which we come to terms with reward and loss.

Psychological adjustment and the facilitative nature of close personal relationships.

PubMed

Cramer, D

1985-06-01

The Rogerian hypothesis that psychological adjustment is positively related to having a relationship which is perceived as being characterized by understanding, congruence and unconditional acceptance was tested in the context of a current, close relationship, using the original Relationship Inventory in two studies which used different measures of assessing psychological adjustment. In the first study 26 females and 19 males completed Phillips' questionnaire which assesses acceptance of self and of others, while in the second study, 98 females and 23 males completed Rosenberg's Self-Esteem Scale and a 30-item symptom checklist. The hypothesis was strongly confirmed for the females but not for the males in both studies.

Cognitive processes and conflict in close relationships: an attribution-efficacy model.

Fincham, F D; Bradbury, T N

1987-12-01

A recently proposed model of cognitive processes underlying conflict in close relationships (Doherty, 1978, 1981a, 1981b) is revised and tested in two studies. Central to the original model are the causal attributions made for conflict and the perceived efficacy or ability to resolve conflict. The model is revised to incorporate judgments of responsibility and to provide a closer link to self-efficacy theory. The first study examines attributions and efficacy expectations in mother-child relationships. As anticipated, only weak evidence was obtained for predictions retained from the original model, high-lighting the relationship-specific nature of cognitive processes for conflict in families. A second study examines husband-wife relationships and provides evidence for the usefulness of an attribution-efficacy model for marital conflict. The attributional component of the model received greater support than that pertaining to efficacy expectations. In both studies, support was obtained for the proposal that the relation between conflict dimensions (e.g., blame) and causal dimensions is mediated by judgments of responsibility. The significance of the revisions to Doherty's model for understanding conflict in close relationships is discussed, and several avenues for further research are outlined.

Does Death of a Family Member Moderate the Relationship between Religious Attendance and Depressive Symptoms? The HUNT Study, Norway

PubMed Central

Sørensen, Torgeir; Danbolt, Lars J.; Holmen, Jostein; Koenig, Harold G.; Lien, Lars

2012-01-01

Background. The death of a family member is a stressful life event and can result in an increased level of depressive symptoms. Previous American research has shown inverse relationships between religious involvement and depression. European investigations are few and findings inconsistent; different contexts may have an important influence on findings. We therefore investigated the relationship between attendance at church/prayer house and depressive symptoms, and whether this relationship was moderated by the death of a close family member, in Norway. Methods. A population-based sample from the Nord-Trøndelag Health Study, Norway (HUNT 3, N = 37,981), was the population examined. Multiple regression and interaction tests were utilised. Results. Religious attendees had lower scores on depressive symptoms than non-attendees; death of a close family member moderated this relationship. The inverse relationships between attendance at church/prayer house and depressive symptoms were greater among those experiencing the death of an immediate family member in the last twelve months compared to those without such an experience, with men's decrease of depressive symptoms more pronounced than women's. Conclusion. In a population-based study in Norway, attendance at church/prayer house was associated with lower depressive symptoms, and the death of a close relative and gender moderated this relationship.

The manifestation of major depressive disorder (MDD) may include cognitive symptoms that can precede the onset of MDD and persist beyond the resolution of acute depressive episodes. However, little is known about how cognitive symptoms are experienced by MDD patients and the people around them. In this international (Brazil, Canada, China, France, and Germany) ethnographic study, we conducted semi-structured interviews and observations of remitted as well as symptomatic MDD patients (all patients self-reported being diagnosed by an HCP and self-reported being on an antidepressant) aged 18-60 years with self-reported cognitive symptoms (N = 34). In addition, participating depressed patients' close family or friends (N = 31) were interviewed. Separately recruited from depressed participants, work colleagues (N = 21) and healthcare providers (HCPs; N = 13) of depressed individuals were interviewed. Key insights were that: (1) patients were generally unaware that their cognitive symptoms were linked to their depression and, instead, attributed these symptoms to negative aspects of their person (e.g., age, separate disease, laziness, exhaustion); (2) cognitive symptoms in MDD appeared to negatively impact patients' social relationships and patients' ability to handle daily tasks at work and at home; (3) patients' cognitive symptoms also impacted relationships with family members and coworkers; (4) patients' cognitive symptoms increased stress and feelings of failure, which in turn seemed to worsen the cognitive symptoms, thereby creating a destructive cycle; and (5) although HCPs recommended that patients re-engage in everyday activities to help overcome their depression, cognitive symptoms seemed to impede such functional recovery. Taken together, these findings highlight a negative impact of patients' cognitive symptoms on their social functioning, work performance, and quality of life on the people close to them, and consequently on the degree of functional recovery after depression.

Research on Jamaican mother–child relationships has had a limited focus on authoritarian parenting styles and selected discipline practices such as corporal punishment. This study examined Jamaican mothers’ experiences of closeness and connectedness with their children to provide a holistic perspective on Jamaican-parent–child relationships. Thirty mothers (17 middle class and 13 lower class) living in Kingston and St. Andrew, Jamaica, participated in a 1-h to 1.5-h semi-structured, open-ended interview regarding their 8- to 12-year-old children. Thematic analyses indicated that mothers experienced closeness through intimate interactions (e.g., shared projects, shared physical affection, mutuality, and child self-disclosure) and parent–child nurturance. Both mothers and children were active in creating contexts for closeness. Mothers also reported experiences that temporarily damaged their connection with their children. The findings suggest that the construct of parent–child intimacy may be useful in teasing out the psychological meanings and interpersonal processes of parent–child relatedness in cultural research.

Multiple group longitudinal cross-lagged panel models were implemented to understand the directional influences between teacher-student closeness and conflict and measured math and reading achievement across elementary grades and gender groups using the National Institute of Child Health and Human Development longitudinal sample (N=1133). Specifically, after testing multiple group longitudinal measurement invariance to ensure consistent measurement across genders and time, and tests of equivalence of the latent parameters, we were interested in whether longitudinal changes in teacher-rated closeness and conflict explained longitudinal changes in achievement, and vice versa, and whether those longitudinal influences varied by gender. Latent teacher-student closeness decreased for both genders over time (Cohen's d=-0.15 to -0.32), but latent conflict increased for males (Cohen's d=0.16). There was also increased heterogeneity in teacher-student relationship quality for males relative to females. Math and reading achievement had medium reciprocal effects (β=0.12 to 0.23), and previous math achievement had small to medium effects on subsequent teacher-student closeness (β=0.08 to 0.11) and conflict (β=-0.07 to -0.09). Teacher-student conflict and closeness did not influence subsequent levels of math or reading achievement once previous levels were controlled. Further, these influences were consistent across gender groups despite latent differences in teacher-student closeness and conflict with teachers reporting closer relationships with female students and more conflictual relationships with male students.

The aim of this qualitative study was to gain a deeper understanding about couples' relationship changes over time (the first six months) after one partner is diagnosed with an incurable advanced melanoma (stage III or IV). In semistructured interviews, eight patients and their partners were asked separately about potential changes in their relationship since diagnosis. The same questions were asked again six months later, but focusing on relationship changes over the preceding six months. Some 32 audiotaped interviews were analyzed applying qualitative content analysis. At baseline (t1), relationship changes were mostly reported in terms of caring, closeness/distance regulation, and communication patterns. While changes in caregiving and distance/closeness regulation remained main issues at six months follow-up (t2), greater appreciation of the relationship and limitations in terms of planning spare time also emerged as major issues. Unexpectedly, 50% of patients and partners reported actively hiding their negative emotions and sorrows from their counterparts to spare them worry. Furthermore, qualitative content analysis revealed relationship changes even in those patients and partners who primarily reported no changes over the course of the disease. Our findings revealed a differentiated and complex picture about relationship changes over time, which also might aid in the development of support programs for couples dealing with advanced cancer, focusing on the aspects of caring, closeness/distance regulation, and communication patterns.

Change in Minimum Orbit Intersection Distance due to General Relativistic Precession in Small Solar System Bodies

NASA Astrophysics Data System (ADS)

2017-06-01

One of the greatest successes of Einstein's General Theory of Relativity (GR) was the correct prediction of the perihelion precession of Mercury. The closed form expression to compute this precession tells us that substantial GR precession would occur only if the bodies have a combination of both moderately small perihelion distance and semi-major axis. Minimum Orbit Intersection Distance (MOID) is a quantity which helps us to understand the closest proximity of two orbits in space. Hence evaluating MOID is crucial to understand close encounters and collision scenarios better. In this work, we look at the possible scenarios where a small GR precession in argument of pericentre can create substantial changes in MOID for small bodies ranging from meteoroids to comets and asteroids.Previous works have looked into neat analytical techniques to understand different collision scenarios and we use those standard expressions to compute MOID analytically. We find the nature of this mathematical function is such that a relatively small GR precession can lead to drastic changes in MOID values depending on the initial value of argument of pericentre. Numerical integrations were done with the MERCURY package incorporating GR code to test the same effects. A numerical approach showed the same interesting relationship (as shown by analytical theory) between values of argument of pericentre and the peaks or dips in MOID values. There is an overall agreement between both analytical and numerical methods.We find that GR precession could play an important role in the calculations pertaining to MOID and close encounter scenarios in the case of certain small solar system bodies (depending on their initial orbital elements) when long term impact risk possibilities are considered. Previous works have looked into impact probabilities and collision scenarios on planets from different small body populations. This work aims to find certain sub-sets of small bodies where GR could play an interesting role. Certain parallels are drawn between the cases of asteroids, comets and small perihelion distance meteoroid streams.

There has been relatively little research on the role of grandparents as a source of support for children during and following their parents' marital transitions. In this study, we examined children's contact with and closeness to grandparents in different family types (i.e., two biological parents, single mother, stepparent). Participants included 155 children from the Avon Brothers and Sisters Study. Parent and child interviews and questionnaires regarding the children's relationships with maternal and paternal biological and stepgrandparents were examined. There were family type differences in rates of contact with grandparents as well as children's closeness to grandparents. Furthermore, children's and parents' view about these relationships with grandparents were modestly correlated, suggesting that children often held different views about their closeness to their grandparents than did their parents. Greater closeness to grandparents was associated with fewer adjustment problems.

The purpose of the present study was to examine the relations of teacher-child relationship quality (close, conflictive, and dependent), children’s social behavior, and peer likability in a sample of Italian preschool-aged children (46 boys; 42 girls). Preschool teachers evaluated the quality of the teacher-child relationship and children’s social behaviors (i.e., social competence, anger-aggression, and anxiety-withdrawal). Peer-rated likability was measured using a sociometric procedure. Results indicated that conflictual teacher-child relationships were related to high aggressive behavior, and dependent teacher-child relationships were positively associated with children’s anxiety-withdrawal. Moreover, we found an indirect association between close teacher-child relationship quality and peer likability through children’s social competence. The findings provide evidence that the teacher-child relationship is critical for children’s social behaviors, and that social competence was uniquely related to peer likability. PMID:24039375

Conflict management in online relationships.

Ishii, Kumi

2010-08-01

With the diffusion of networked technology, personal relationships can be easily formed and maintained online today. Similar to a face-to-face situation, conflict is also seen in these online relationships. Early theories suggested that computer-mediated communication (CMC) tends to increase conflicts because of the lack of social-context cues, and CMC is not rich enough to manage conflict. As CMC has become part of our daily life, we often face conflict online, and thus we need to understand how people manage conflict online. This study explored how online users manage interpersonal conflict. Self-report survey data from 159 university students were analyzed to examine their conflict-management styles in association with the perceived closeness of the online relationship and a future intention toward the relationship. The results indicated that online users select cooperative management styles to handle conflict in their close relationships. In addition, online users avoid less cooperative styles when they want to continue the relationship.

Bacteria on display-can we, and should we? Artistically exploring the ethics of public engagement with science in microbiology.

Fawcett, Nicola J; Dumitriu, Anna

2018-06-01

The field of microbiology presents unique opportunities, and accompanying challenges, for artistic collaborations. On one hand, artistic works enable exploration of the aesthetics and of issues in biomedical science and new technologies, and draw in new, non-scientific audiences. On the other hand, creating art with microbes requires rigorous consideration of health and safety. Artists working in this field, known as Bio Art, tend to want to push the boundaries of what is possible or 'known', and work with new biomedical tools as they become available. However, when an artist's proposed work is raising novel questions where the risks are not fully understood, who should decide if the benefits outweigh the consequences? The reflections of an art-collaborating scientist are related. Also, considered is how close working relationships between disciplines can enable new ethical frameworks that consider these decisions, respecting artists' endeavours as a beneficial form of research in its own right, and even learning from the rich perspectives of artists to broaden reflections on the practice of science.

Interprofessional Relationships between Orthopaedic and Podiatric Surgeons in the UK

2008-01-01

INTRODUCTION The first comprehensive report on the interprofessional relationships between foot and ankle surgeons in the UK is presented. MATERIALS AND METHODS A questionnaire was sent to orthopaedic surgeons with membership of the British Foot and Ankle Surgery Society (BOFAS), orthopaedic surgeons not affiliated to the specialist BOFAS and podiatrists specialising in foot surgery. The questionnaire was returned by 77 (49%) of the BOFAS orthopaedic consultant surgeons, 66 (26%) of non-foot and ankle orthopaedic consultant surgeons and 99 (73%) of the podiatric surgeons. RESULTS While most respondents have experience of surgeons working in the other specialty in close geographical proximity, the majority do not believe that this has adversely affected their referral base. The experience of podiatrists of the outcomes of orthopaedic surgery has been more positive than orthopaedic surgeons of podiatric interventions. Podiatrists are more welcoming of future orthopaedic involvement in future foot and ankle services than in reverse. However, there are a sizeable number of surgeons in both professions who would like to see closer professional liaisons. The study has identified clear divisions between the professions but has highlighted areas where there is a desire from many clinicians to work more harmoniously together, such as in education, training and research. CONCLUSIONS While major concerns exist over issues such as surgery by non-registered medical practitioners and the suitable spectrum of surgery for each profession, many surgeons, in both professions, are willing to provide training for juniors in both specialties and there is a wish to have closer working relationships and common educational and research opportunities than exists at present.

A Phenomenological Model and Validation of Shortening Induced Force Depression during Muscle Contractions

2009-01-01

History dependent effects on muscle force development following active changes in length have been measured in a number of experimental studies. However, few muscle models have included these properties or examined their impact on force and power output in dynamic cyclic movements. The goal of this study was to develop and validate a modified Hill-type muscle model that includes shortening induced force depression and assess its influence on locomotor performance. The magnitude of force depression was defined by empirical relationships based on muscle mechanical work. To validate the model, simulations incorporating force depression were developed to emulate single muscle in situ and whole muscle group leg extension experiments. There was excellent agreement between simulation and experimental values, with in situ force patterns closely matching the experimental data (average RMS error < 1.5 N) and force depression in the simulated leg extension exercise being similar in magnitude to experimental values (6.0% vs 6.5%, respectively). To examine the influence of force depression on locomotor performance, simulations of maximum power pedaling with and without force depression were generated. Force depression decreased maximum crank power by 20% – 40%, depending on the relationship between force depression and muscle work used. These results indicate that force depression has the potential to substantially influence muscle power output in dynamic cyclic movements. However, to fully understand the impact of this phenomenon on human movement, more research is needed to characterize the relationship between force depression and mechanical work in large muscles with different morphologies.

Healthcare and Catholic identity in the universal Church.

PubMed

Danneels, C D

1987-10-01

Two topics that are closely related to the daily work and the primordial concern of Catholic healthcare givers are the meaning and sense of Catholic healthcare institutions, and the relationship between a particular Church and the universal Church, especially since the Second Vatican Council. Some question whether it is worthwhile to maintain independent Catholic institutions, rather than working with others in nondenominational healthcare institutions. Christian institutions are indispensable as a defense against the well-organized forces of evil in the world, and because togetherness is needed in the struggle for good and for faith. Without this togetherness, the danger exists that the power of faith will be taken over by the power of money and financial interest groups. The elements of the Catholic identity of institutions and organizations are a service to the world, the Gospel message, a balance between technology and humanism, a permanent solicitude for the whole person, and a respect for human liberty. This Catholic identity must be fostered in our institutions, especially among the laypeople working there. The relationship between the universal Church and local Churches has come under stress since the Second Vatican Council, and a balance must be found. The problem has two aspects: the theological, and the cultural and psychological. A sound communion theology must be established to provide a good perspective on the relationship. In addition, a dialogue must be established between Rome and the particular Churches to prevent the universal message of Christ in his Gospel from conflicting more and more with local styling of the message.(ABSTRACT TRUNCATED AT 250 WORDS)

Silex Microsystems handles a wide range of customized MEMS components. This speech will be describing Silex's MEMS foundry work model for providing customized solutions based on MEMS in a cost effective and well controlled manner. Factors for success are the capabilities to reformulate a customer product concept to manufacturing processes in the wafer fab, using standard process modules and production equipment. A well-controlled system increases the likelihood of a first batch success and enables fast ramp-up into volume production. The following success factors can be listed: strong enduring relationships with the customers; highly qualified well-experienced specialists working close with the customer; process solutions and building blocks ready to use out of a library; addressing manufacturing issues in the early design phase; in-house know how to meet demands for volume manufacturing; access to a wafer fab with high capacity, good organization, high availability of equipment, and short lead times; process development done in the manufacturing environment using production equipment for easy ramp-up to volume production. The article covers a method of working to address these factors: to have a long and enduring relationships with customers utilizing MEMS expertise and working close with customers, to translate their product ideas to MEMS components; to have stable process solutions for features such as Low ohmic vias, Spiked electrodes, Cantilevers, Silicon optical mirrors, Micro needles, etc, which can be used and modified for the customer needs; to use a structured development and design methodology in order to handle hundreds of process modules, and setting up standard run sheets. It is also very important to do real time process development in the manufacturing line. It minimizes the lead-time for the ramp-up of production; to have access to a state of the art Wafer Fab which is well organized, controlled and flexible, with high capacity and short lead-time for prototypes. It is crucial to have intimate control of processes, equipment, organization, production flow control and WIP. This has been addressed by using a fully computerized control and reporting system.

Automated assessment and prediction of marital outcome in couples therapy is a challenging task but promises to be a potentially useful tool for clinical psychologists. Computational approaches for inferring therapy outcomes using observable behavioral information obtained from conversations between spouses offer objective means for understanding relationship dynamics. In this work, we explore whether the acoustics of the spoken interactions of clinically distressed spouses provide information towards assessment of therapy outcomes. The therapy outcome prediction task in this work includes detecting whether there was a relationship improvement or not (posed as a binary classification) as well as discerning varying levels of improvement or decline in the relationship status (posed as a multiclass recognition task). We use each interlocutor’s acoustic speech signal characteristics such as vocal intonation and intensity, both independently and in relation to one another, as cues for predicting the therapy outcome. We also compare prediction performance with one obtained via standardized behavioral codes characterizing the relationship dynamics provided by human experts as features for automated classification. Our experiments, using data from a longitudinal clinical study of couples in distressed relations, showed that predictions of relationship outcomes obtained directly from vocal acoustics are comparable or superior to those obtained using human-rated behavioral codes as prediction features. In addition, combining direct signal-derived features with manually coded behavioral features improved the prediction performance in most cases, indicating the complementarity of relevant information captured by humans and machine algorithms. Additionally, considering the vocal properties of the interlocutors in relation to one another, rather than in isolation, showed to be important for improving the automatic prediction. This finding supports the notion that behavioral outcome, like many other behavioral aspects, is closely related to the dynamics and mutual influence of the interlocutors during their interaction and their resulting behavioral patterns.

MicroRNAs have close relationship with human diseases. Therefore, identifying disease related MicroRNAs plays an important role in disease diagnosis, prognosis and therapy. However, designing an effective computational method which can make good use of various biological resources and correctly predict the associations between MicroRNA and disease is still a big challenge. Previous researchers have pointed out that there are complex relationships among microRNAs, diseases and environment factors. There are inter-relationships between microRNAs, diseases or environment factors based on their functional similarity or phenotype similarity or chemical structure similarity and so on. There are also intra-relationships between microRNAs and diseases, microRNAs and environment factors, diseases and environment factors. Moreover, functionally similar microRNAs tend to associate with common diseases and common environment factors. The diseases with similar phenotypes are likely caused by common microRNAs and common environment factors. In this work, we propose a framework namely ThrRWMDE which can integrate these complex relationships to predict microRNA-disease associations. In this framework, microRNA similarity network (MFN), disease similarity network (DSN) and environmental factor similarity network (ESN) are constructed according to certain biological properties. Then, an unbalanced three random walking algorithm is implemented on the three networks so as to obtain information from neighbors in corresponding networks. This algorithm not only can flexibly infer information from different levels of neighbors with respect to the topological and structural differences of the three networks, but also in the course of working the functional information will be transferred from one network to another according to the associations between the nodes in different networks. The results of experiment show that our method achieves better prediction performance than other state-of-the-art methods.

A change in life as experienced by first-time fathers.

Research suggests that the attitude of men towards pregnancy, childbirth and child-caring is different from that of women. Up to now, research has focused mainly on motherhood. The aim of this study was to explore first-time fathers' experiences during early infancy of their children. Grounded theory and constant comparative method were used and 20 fathers aged 20-48 participated. Interviews were carried out in 2002-2003. 'Changing life' emerged as the core category consisting of the categories: becoming a father, alternating between work and home, changing relationship towards partner and developing relationship with their child. Changing life implied that they have left bachelor life and become responsible for a child. Becoming a father was much more fantastic than they could have imagined and they suggested that they performed childcare to the same extent as the mother when both parents were at home. Still fathers viewed the mother as the main parent, partly because of their alternating between work and home and because the mothers breast-feed the infants. Fathers' attitude towards breast-feeding seemed to be ambiguous; it was a matter of necessity, but made them feel insignificant. Changing relationship towards partner was common but it was not necessarily for the worst and often resulted in a more closely united relationship. However, tiredness because of lack of sleep could result in increased irritability towards problems. Developing relationship with their child implied increasing possibilities to learn to know the infant's signals. Fathers are one of two parents, and hence are important for their child's growth and development, emotional health and cognitive development. Knowledge about first-time fathers' experiences during the early infancy of their children may bring about increased support from midwives and child health nurses.

The study examines the influence of personality traits and close relationships on the coping style of women with breast cancer. A sample of 72 Italian patients receiving treatment for early stage breast cancer was recruited. Participants completed questionnaires measuring personality traits (Interpersonal Adaptation Questionnaire), interpersonal closeness (Inclusion of the Other in the Self Scale), and adjustment to cancer (Mini-Mental Adjustment to Cancer Scale). We hypothesized that diverse personality traits and degrees of closeness contribute to determine the coping styles shown by participants. Multiple regression analyses were conducted for each of the five coping styles (Helplessness/Hopelessness, Anxious Preoccupation, Avoidance, Fatalism, and Fighting Spirit) using personality traits and interpersonal closeness variables (Strength of Support Relations, and Number of Support Relations) as predictors. Women who rated high on assertiveness and social anxiety were more likely to utilize active coping strategies (Fighting Spirit). Perceived strength of relationships was predictive of using an active coping style while the number of supportive relationships did not correlate with any of the coping styles. Implications for assessment of breast cancer patients at risk for negative adaptation to the illness and the development of psychosocial interventions are discussed.

The Relationship Between Perceived Hookup Attitudes and Negative Hookup Consequences: Do Perceived Attitudes of Close Friends Matter?

Montes, Kevin S; Blanco, Lyzette; LaBrie, Joseph W

2017-01-01

Research suggests that the perceived hookup attitudes of close referents are generally a poor predictor of hookup behavior and likely a poor direct predictor of negative hookup consequences. The current study aimed to examine three intervening variables as mediators of the relationship between the perceived hookup attitudes of college students' close friends and negative hookup consequences (e.g., regret, embarrassment). Self-report data were collected from 589 heavy-drinking college students from three midsized universities. The results indicated that students' own attitudes toward hooking up, motivation to hook up, and self-reported number of hookup partners significantly mediated the relationship between the perceived hookup attitudes of close friends and negative hookup consequences. The perceived hookup attitudes of close friends were positively associated with participants' attitudes toward hooking up. Participants' attitudes toward hooking up were positively associated with social-sexual motivation to hook up. Elevated social-sexual motivation to hook up was positively associated with hooking up with multiple partners, with hooking up with multiple partners positively associated with negative hookup consequences. A better understanding of the predictors and mediators of negative hookup consequences has the potential to inform prevention and intervention efforts.

Relational mobility explains between- and within-culture differences in self-disclosure to close friends.

PubMed

Schug, Joanna; Yuki, Masaki; Maddux, William

2010-10-01

In the current research, we tested a novel explanation for previously demonstrated findings that East Asians disclose less personal information to other people than do Westerners. We propose that both between- and within-culture differences in self-disclosure to close friends may be explained by the construct of relational mobility, the general degree to which individuals in a society have opportunities to form new relationships and terminate old ones. In Study 1, we found that cross-cultural differences (Japan vs. United States) in self-disclosure to a close friend were mediated by individuals' perceptions of relational mobility. In Study 2, two separate measures of relational mobility predicted self-disclosure within a single culture (Japan), and this relationship was mediated by the motivation to engage in self-disclosure to strengthen personal relationships. We conclude that societies and social contexts higher in relational mobility (in which relationships can be formed and dissolved relatively easily) produce stronger incentives for self-disclosure as a social-commitment device.

Disparities in Social Health by Sexual Orientation and the Etiologic Role of Self-Reported Discrimination.

Some past work indicates that sexual minorities may experience impairments in social health, or the perceived and actual availability and quality of one's social relationships, relative to heterosexuals; however, research has been limited in many ways. Furthermore, it is important to investigate etiological factors that may be associated with these disparities, such as self-reported discrimination. The current work tested whether sexual minority adults in the United States reported less positive social health (i.e., loneliness, friendship strain, familial strain, and social capital) relative to heterosexuals and whether self-reported discrimination accounted for these disparities. Participants for the current study (N = 579) were recruited via Amazon's Mechanical Turk, including 365 self-identified heterosexuals (105 women) and 214 sexual minorities (103 women). Consistent with hypotheses, sexual minorities reported impaired social health relative to heterosexuals, with divergent patterns emerging by sexual orientation subgroup (which were generally consistent across sexes). Additionally, self-reported discrimination accounted for disparities across three of four indicators of social health. These findings suggest that sexual minorities may face obstacles related to prejudice and discrimination that impair the functioning of their relationships and overall social health. Moreover, because social health is closely related to psychological and physical health, remediating disparities in social relationships may be necessary to address other health disparities based upon sexual orientation. Expanding upon these results, implications for efforts to build resilience among sexual minorities are discussed.

Conflict of interest: none declared. Introduction Employees’ job satisfaction and commitment depends upon the leadership style of managers. This study clarifies further the relationships between leadership behaviors of managers and two employees’ work-related attitudes-job satisfaction and organizational at public hospitals in Iran. A better understanding of these issues and their relationships can pinpoint better strategies for recruiting, promotion, and training of future hospital managers and employees, particularly in Iran but perhaps in other societies as well. Methods This cross-sectional study was conducted using self-administered questionnaires distributed among 814 hospital employees and managers through a stratified random sampling. Results and discussion The dominant leadership style of hospital managers was participative style. Hospital employees were moderately satisfied with their jobs and committed to their organization. Salaries, benefits, promotion, contingent rewards, interpersonal relationships and working conditions were the best predictors of job satisfaction among hospitals employees. Leadership, job satisfaction and commitment were closely interrelated. The leadership behavior of managers explained 28% and 20% of the variations in job satisfaction and organizational commitment respectively. Conclusion This study clarifies the causal relations of job satisfaction and commitment, and highlights the crucial role of leadership in employees’ job satisfaction and commitment. Nevertheless, participative management is not always a good leadership style. Managers should select the best leadership style according to the organizational culture and employees’ organizational maturity. PMID:24082837

2009-01-01

A fluid mixer plug has holes formed therethrough such that a remaining portion is closed to fluid flow. The plug's inlet face defines a central circuit region and a ring-shaped region with the ring-shaped region including at least some of the plug's remaining portion so-closed to fluid flow. This remaining portion or closed region at each radius R of the ring shaped region satisfies a radius independent, flow-based relationship. Entry openings are defined in the plug's inlet face in correspondence with the holes. The entry openings define an open flow area at each radius of the ring-shaped region. The open flow area at each such radius satisfies the inverse of the flow-based relationship defining the closed regions of the plug.

Negative exchanges in social relationships have traditionally been studied as having negative consequences. This study explored whether they might have positive effects for relationship closeness. The sample included 351 adults, aged between 18 and 91 years, residing in Hong Kong, China. Closeness of social partners to the participants was measured by the Social Convoy Questionnaire, and the levels of negative exchanges and social support from each social partner were assessed. Multilevel analyses revealed that more negative exchanges were associated with a more positive change in closeness over a 2-year period, even after statistically controlling for social support and sociostructural characteristics of the participant and the social partner. Findings extended our knowledge on the positive effects of negative exchanges and their moderating conditions.

New Evidence on Causal Relationship between Approximate Number System (ANS) Acuity and Arithmetic Ability in Elementary-School Students: A Longitudinal Cross-Lagged Analysis.

Approximate number system (ANS) acuity and mathematical ability have been found to be closely associated in recent studies. However, whether and how these two measures are causally related still remain less addressed. There are two hypotheses about the possible causal relationship: ANS acuity influences mathematical performances, or access to math education sharpens ANS acuity. Evidences in support of both hypotheses have been reported, but these two hypotheses have never been tested simultaneously. Therefore, questions still remain whether only one-direction or reciprocal causal relationships existed in the association. In this work, we provided a new evidence on the causal relationship between ANS acuity and arithmetic ability. ANS acuity and mathematical ability of elementary-school students were measured sequentially at three time points within one year, and all possible causal directions were evaluated simultaneously using cross-lagged regression analysis. The results show that ANS acuity influences later arithmetic ability while the reverse causal direction was not supported. Our finding adds a strong evidence to the causal association between ANS acuity and mathematical ability, and also has important implications for educational intervention designed to train ANS acuity and thereby promote mathematical ability.

Phylogeny of Celastrus L. (Celastraceae) inferred from two nuclear and three plastid markers.

This is the first comprehensive molecular investigation of the genus Celastrus L. Phylogenetic relationships within the genus were assessed based on sequences of two nuclear (ETS, ITS) and three plastid (psbA-trnH, rpl16 and trnL-F) regions using the Bayesian inference and the maximum parsimony methods. Our results show that Celastrus, together with Tripterygium, formed a maximal supported clade. Within the cluster, Celastrus is composed of a basal clade and a core Celastrus clade, and the latter is consisted of six subclades. Relationships among species are more influenced by latitude than continental distribution patterns. The cauline cyme and lunate seeds are distinct characters to one of the maximal supported subclades. Their close relationship, similar geographical pattern and habitat imply that C. flagellaris may be a potential invasive species threatening C. scandens in North America. Celastrus leiocarpus, C. oblanceifolius and C. rugosus are confirmed as synonyms of C. punctatus, C. aculeatus and C. glaucophyllus, respectively. Discordance between the molecular data and previous morphology-based subgeneric classifications are noted. More works are needed to clarify the relationship between Celastrus and Tripterygium and the species within Celastrus.

The objective of the current work was to evaluate the spectrum-effect relationships between high-performance liquid chromatography fingerprints and analgesic and anti-inflammatory effects of Rubia cordifolia L. extract (RCE), and to identify active components of RCE. Chemical fingerprints of ten batches of RC from various sources were obtained by HPLC, and similarity and hierarchical clustering analyses were carried out. Pharmacodynamic assays were performed in adjuvant-induced arthritis rat model to assess the analgesic and anti-inflammatory properties of RCE. The spectrum-effect relationships between chemical fingerprints and the analgesic and anti-inflammatory effects of RCE were established by gray correlation analysis. UPLC-ESI-MS was used to identify the structures of potential active components, by reference standards comparison. The results showed that a close correlation existed between chemical fingerprints with analgesic and anti-inflammatory activities, and alizarin, 6-hydroxyrubiadin, purpurin and rubiadin might be the active constituents of RCE. In addition, RCE attenuated pathological changes in adjuvant-induced arthritis. The current findings provide a strong basis for combining chemical fingerprints with analgesic and anti-inflammatory activities in assessing the spectrum-effect relationships of RCE.

Enhanced dimension-specific visual working memory in grapheme–color synesthesia☆

2013-01-01

There is emerging evidence that the encoding of visual information and the maintenance of this information in a temporarily accessible state in working memory rely on the same neural mechanisms. A consequence of this overlap is that atypical forms of perception should influence working memory. We examined this by investigating whether having grapheme–color synesthesia, a condition characterized by the involuntary experience of color photisms when reading or representing graphemes, would confer benefits on working memory. Two competing hypotheses propose that superior memory in synesthesia results from information being coded in two information channels (dual-coding) or from superior dimension-specific visual processing (enhanced processing). We discriminated between these hypotheses in three n-back experiments in which controls and synesthetes viewed inducer and non-inducer graphemes and maintained color or grapheme information in working memory. Synesthetes displayed superior color working memory than controls for both grapheme types, whereas the two groups did not differ in grapheme working memory. Further analyses excluded the possibilities of enhanced working memory among synesthetes being due to greater color discrimination, stimulus color familiarity, or bidirectionality. These results reveal enhanced dimension-specific visual working memory in this population and supply further evidence for a close relationship between sensory processing and the maintenance of sensory information in working memory.

The masticatory muscles play an important part in determining the morphology of the facial skeleton. Skeletal typology and the characteristics of the masticatory muscles are closely linked. Several authors have studied muscle characteristics as related to facial typology. The aim of this work is to study the relationship between vertical and transverse skeletal dimensions and the dimensions (length, width and thickness) of two muscles of mastication, the masseter and the lateral pterygoid. Our study was based on CT-scan examinations of a sample composed of patients consulting the X-ray department of the Rabat-Salé Teaching Hospital, and for whom a CT-scan had been requested. Forty CT examinations of the skull, performed in the context of sinus explorations or pre-surgical work-ups in the radiology department of the Rabat-Salé Teaching Hospital, were selected for this study. The sample comprised 19 women and 21 men aged between 20 and 45, with a mean of 40.9 ± 12.8. A Siemens 32-row 64-slice spiral CT-scan device was used for spiral acquisition of data around the facial bones, with the mouth closed. The study was carried out in the parenchymal window for the muscle measurements, in the axial and coronal planes. Bone measurements were performed after 3D reconstruction in VRT mode. Our study showed that, for the masseter muscle, thickness is the dimension that correlates significantly with skeletal dimensions in the vertical, transverse and sagittal directions. For the lateral pterygoid muscle, length and width both present significant correlations with transverse skeletal dimensions. Analysis of these results shows that the dimensional characteristics of the masticatory muscles vary according to the vertical and transverse skeletal typology of the subjects concerned.

We examined the extent to which individual relationships with mother and father, social support from partner, and quality of the relationship with the partner, are related to work orientation and work ethic. Survey data were obtained from 3841 respondents from the Netherlands Kinship Panel Study (wave 2). The results showed that, overall, people with a more positive relationship with their parents had a more positive work orientation and a stronger work ethic. A positive relationship with the father had a greater influence on these work aspects than a positive relationship with the mother, particularly for men. Partner support and the quality of the partner relationship partially mediated the association between the relationship with one's parents and work orientation only for women. There were no significant relationships between partner support or the quality of the partner relationship, and work ethic. Research on the relationship with parents and work-related variables is discussed.

It is well known that astrological practice during the Early Modern period was closely related to medicine, and that it provided a tool for diagnosis and treatments. An interesting aspect of this relationship of medicine and astrology is the recognition of the prevailing ideas about medical astrology in the astrological works and astrological-medical treatises. This article discusses the ideas of Galenism and the astrological doctrines that established such a strong relationship between astrology and medicine. There is an overview of the Spanish authors who wrote about the subject, especially those linked with the universities. The paper then goes into detail about the examples of these ideas found in the Spanish printed texts of the seventeenth century. Finally, there is a section on some very interesting and little known treatises on medical astrology which were a reference for the practice of astrological medicine in the period.

The promise of electronic decision support to promote evidence based practice remains elusive in the context of chronic disease management. We examine the problem of achieving a close relationship of Electronic Health Record (EHR) content to other components of a clinical information system (guidelines, decision support and work-flow), particularly linking the decisions made by providers back to the guidelines. We use the openEHR architecture, which allows extension of a core Reference Model via Archetypes to refine the detailed information recording options for specific classes of encounter. We illustrate the use of openEHR for tracking the relationship of a series of clinical encounters to a guideline via a case study of guideline-compliant treatment of hypertension in diabetes. This case study shows the contribution guideline content can have on problem-specific EHR structure and demonstrates the potential for a constructive interaction of electronic decision support and the EHR.

2014-02-01

This article focuses on the relational treatment of a male patient presenting with sexual and erotic feelings toward the therapist. The use of relational psychotherapy allowed us to collaborate in viewing our therapeutic relationship as a microcosm of other relationships throughout the patient's life. In this way, the patient came to understand his fears of being close to women, his discomfort with his sexuality, and how these feelings impacted his ongoing romantic and sexual experiences. Use of the therapist's reactions to the patient, including conscious and unconscious feelings and behaviors, aided in the conceptualization of this case. Working under a relational model was especially helpful when ruptures occurred, allowing the patient and therapist to address these moments and move toward repair. The patient was successful in making use of his sexual feelings to understand his feelings and behaviors across contexts. © 2013 Wiley Periodicals, Inc.

Logistic regression and artificial neural networks have been developed as two non-linear models to establish quantitative structure-activity relationships between structural descriptors and biochemical activity of adenosine based competitive inhibitors, toward adenosine deaminase. The training set included 24 compounds with known k {sub i} values. The models were trained to solve two-class problems. Unlike the previous work in which multiple linear regression was used, the highest of positive charge on the molecules was recognized to be in close relation with their inhibition activity, while the electric charge on atom N1 of adenosine was found to be a poor descriptor. Consequently, themore » previously developed equation was improved and the newly formed one could predict the class of 91.66% of compounds correctly. Also optimized 2-3-1 and 3-4-1 neural networks could increase this rate to 95.83%.« less

Tetrametallic molecular catalysts for photochemical water oxidation.

2013-03-21

Among molecular water oxidation catalysts (WOCs), those featuring a reactive set of four multi-redox transition metals can leverage an extraordinary interplay of electronic and structural properties. These are of particular interest, owing to their close structural, and possibly functional, relationship to the oxygen evolving complex of natural photosynthesis. In this review, special attention is given to two classes of tetrametallic molecular WOCs: (i) M(4)O(4) cubane-type structures stabilized by simple organic ligands, and (ii) systems in which a tetranuclear metal core is stabilized by coordination of two polyoxometalate (POM) ligands. Recent work in this rapidly evolving field is reviewed, with particular emphasis on photocatalytic aspects. Special attention is given to studies addressing the mechanistic complexity of these systems, sometimes overlooked in the rush for oxygen evolving performance. The complementary role of molecular WOCs and their relationship with bulk oxides and heterogeneous catalysis are discussed.

This qualitative inquiry explored the processes and practices of collaboration as experienced by a group of Australian multidisciplinary Aboriginal and non-Aboriginal health workers. Each worker had participated, for a period of 2 to 5 years, in an Australian Government–funded project in which a range of health initiatives led to improved access to cancer services by Aboriginal communities in a rural region of South Eastern Australia. Initiatives which addressed high rates of mortality from cancer, poor access to cancer screening, and engagement with cancer treatment were developed through the formation of close working relationships between Aboriginal and non-Aboriginal health workers. These relationships were regarded as personally and professionally transformative. Through the sharing of knowledge, skills, and experiences, new ways of knowing, being, and doing emerged. Developing a deeper understanding of cross-cultural collaboration is one way of addressing complex health problems and building the capacity of the health workforce. PMID:28682709

The philosophy of science yields 3 important functions in the teaching of medical history. Firstly, by analyzing the development of medicine from the perspective of philosophy, we can integrate medical history into the history of human thought and clearly show the close connection between the development of humanity and the development of medical science. Secondly, philosophical analysis on the general rules of scientific discoveries involved in medical history can help medical students to understand the methodology in the research of sciences in history. Thirdly, philosophy of science offers new dimensions for understanding the relationship between medicine and the society. By making use of the relevant theory in scientific philosophy to explore the relationship between medicine and the society, the nature of medicine and the social nature and function of science can be further understood by medical students so as to exert an active role in the research and clinical work in the future.

The purpose of this study was to translate the Experience of Close Relationship-Relationship Structure (ECRRS) and evaluate its validity. In study 1 (N = 982), evidence based internal structure (factor structure, internal consistency, and correlation among sub-scales) and evidence based relations to other variables (depression, reassurance seeking and self-esteem) were confirmed. In study 2 (N = 563), evidence based on internal structure was reconfirmed, and evidence based relations to other variables (IWMS, RQ, and ECR-GO) were confirmed. In study 3 (N = 342), evidence based internal structure (test-retest reliability) was confirmed. Based on these results, we concluded that ECR-RS was valid for measuring adult attachment style.

Adolescents' and parents' reactions to pubertal development are hypothesized to contribute to changes in family dynamics. Using 7-year longitudinal data from the NICHD-SECCYD (488 boys, 475 girls) we examined relations between pubertal development (timing, tempo) and trajectories (developmental change and year-to-year lability) of parent-child conflict and closeness from age 8.5 to 15.5 years. Changes were mostly characterized by year-to-year fluctuations – lability. Parent-child conflict increased and closeness decreased some with age. Pubertal timing and tempo were more consistently associated with lability in parent-child relationships than with long-term trends, although faster tempo was associated with steeper decreases in parent-child closeness. Findings provide a platform for examining how puberty contributes to both long-term and transient changes in adolescents' relationships and adjustment. PMID:26321856

The authors examined attitudes and behaviors regarding close relationships between European and Asian Americans, with a particular emphasis on 5 major subgroups of Asian Americans (Chinese, Japanese, Korean, Vietnamese, and Filipino Americans). Participants were 218 Asian American college students and 171 European American college students attending a culturally diverse university. The European Americans did not differentiate among the various subgroups of Asian Americans. Their attitudes regarding close relationships were less positive toward Asian Americans than toward Mexican and African Americans, a finding contrary to the prediction of social exchange theory (H. Tajfel, 1975). In contrast to the European Americans' view of homogeneity among Asian Americans, the 5 major subgroups of Asian Americans expressed a distinctive hierarchy of social preference among themselves. Results are discussed in terms of their implications for future research on interethnic relations involving Asian Americans.

Hylocereus and Selenicereus are native to tropical and sub-tropical America. Based on its taxonomic status and crossability relations it was postulated that H. megalanthus (syn. S. megalanthus) is an allotetraploid (2n = 4x = 44) derived from natural hybridization between two closely related diploid taxa. The present work aimed at elucidating the genetic relationships between species of the two genera. Crosses were performed and the putative hybrids were analysed by chromosome counts and morphological traits. The ploidy level of hybrids was confirmed by fluorescent in situ hybridization (FISH) of rDNA sites. Genomic in situ hybridization (GISH) was used in an attempt to identify the putative diploid genome donors of H. megalanthus and an artificial interploid hybrid. Reciprocal crosses among four diploid Hylocereus species (H. costaricensis, H. monacanthus (syn. H. polyrhizus), H. undatus and Hylocereus sp.) yielded viable diploid hybrids, with regular chromosome pairing. Reciprocal crosses between these Hylocereus spp. and H. megalanthus yielded viable triploid, pentaploid, hexaploid and aneuploid hybrids. Morphological and phenological traits confirm the hybrid origin. In situ detection of rDNA sites was in accord with the ploidy status of the species and hybrid studied. GISH results indicated that overall sequence composition of H. megalanthus is similar to that of H. ocamponis and S. grandiflorus. High sequence similarity was also found between the parental genomes of H. monacanthus and H. megalanthus in one triploid hybrid. The ease of obtaining partially fertile F1 hybrids and the relative sequence similarity (in GISH study) suggest close genetic relationships among the taxa analysed.

Physical context for theoretical approaches to sediment transport magnitude-frequency analysis in alluvial channels

2014-10-01

Theoretical approaches to magnitude-frequency analysis (MFA) of sediment transport in channels couple continuous flow probability density functions (PDFs) with power law flow-sediment transport relations (rating curves) to produce closed-form equations relating MFA metrics such as the effective discharge, Qeff, and fraction of sediment transported by discharges greater than Qeff, f+, to statistical moments of the flow PDF and rating curve parameters. These approaches have proven useful in understanding the theoretical drivers behind the magnitude and frequency of sediment transport. However, some of their basic assumptions and findings may not apply to natural rivers and streams with more complex flow-sediment transport relationships or management and design scenarios, which have finite time horizons. We use simple numerical experiments to test the validity of theoretical MFA approaches in predicting the magnitude and frequency of sediment transport. Median values of Qeff and f+ generated from repeated, synthetic, finite flow series diverge from those produced with theoretical approaches using the same underlying flow PDF. The closed-form relation for f+ is a monotonically increasing function of flow variance. However, using finite flow series, we find that f+ increases with flow variance to a threshold that increases with flow record length. By introducing a sediment entrainment threshold, we present a physical mechanism for the observed diverging relationship between Qeff and flow variance in fine and coarse-bed channels. Our work shows that through complex and threshold-driven relationships sediment transport mode, channel morphology, flow variance, and flow record length all interact to influence estimates of what flow frequencies are most responsible for transporting sediment in alluvial channels.

'Caring for' behaviours that indicate to patients that nurses 'care about' them.

This paper is a report of a study to explore what constitutes nurse-patient interactions and to ascertain patients' perceptions of these interactions. Nurses maintain patient integrity through caring practices. When patients feel disempowered or that their integrity is threatened they are more likely to make a complaint. When nurses develop a meaningful relationship with patients they recognize and address their concerns. It is increasingly identified in the literature that bureaucratic demands, including increased workloads and reduced staffing levels, result in situations where the development of a 'close' relationship is limited. Data collection took two forms: twelve 4-hour observation periods of nurse-patient interactions in one cubicle (of four patients) in a medical and a surgical ward concurrently over a 4-week period; and questionnaires from inpatients of the two wards who were discharged during the 4-week data collection period in 2005. Observation data showed that nurse-patient interactions were mostly friendly and informative. Opportunities to develop closeness were limited. Patients were mostly satisfied with interactions. The major source of dissatisfaction was when patients perceived that nurses were not readily available to respond to specific requests. Comparison of the observation and survey data indicated that patients still felt 'cared for' even when practices did not culminate in a 'connected' relationship. The findings suggest that patients believe that caring is demonstrated when nurses respond to specific requests. Patient satisfaction with the service is more likely to be improved if nurses can readily adapt their work to accommodate patients' requests or, alternatively, communicate why these requests cannot be immediately addressed.

A factory survey on dose-response relationship in toluene toxicity was conducted in 1985-1989 in four cities in China. The examination items consisted of personal diffusive sampling for TWA exposure measurement, questionnaires on subjective symptoms, hematology and serum biochemistry, and clinical examination including simple neurology tests. Hippuric acid was also determined in urine samples collected at the end of the shift. With selection criteria that (1) complete results were available on all study items and (2) valid toluene exposure data (i.e., toluene shared 90% or more of the exposure) were obtained for the exposed, 452 toluene-exposed workers (206 men and 246more » women; toluene exposure at 24.7 ppm as GM) and 517 nonexposed controls (246 men and 271 women) were selected. The subjective symptoms increased in close association with the intensity of exposure to toluene; the threshold concentration appeared to exist at 100 ppm in the case of symptoms during work, and it might be at 50-100 ppm when symptoms off work were evaluated. During the work with exposure at higher concentrations, various symptoms possibly related to CNS or local effects (e.g., eyes, nose, and throat) were complained, and dizziness and floating sensations were identified as typical symptoms with significant dose-response relationship. Several symptoms persisted off work, most of which were apparently related but not necessarily limited to CNS effects. Hematology and serum biochemistry were essentially negative. 46 refs., 4 figs., 6 tabs.« less

Online assessment of risk factors for dementia and cognitive function in healthy adults.

Several potentially modifiable risk factors for cognitive decline and dementia have been identified, including low educational attainment, smoking, diabetes, physical inactivity, hypertension, midlife obesity, depression, and perceived social isolation. Managing these risk factors in late midlife and older age may help reduce the risk of dementia; however, it is unclear whether these factors also relate to cognitive performance in older individuals without dementia. Data from 14 201 non-demented individuals aged >50 years who enrolled in the online PROTECT study were used to examine the relationship between cognitive function and known modifiable risk factors for dementia. Multivariate regression analyses were conducted on 4 cognitive outcomes assessing verbal and spatial working memory, visual episodic memory, and verbal reasoning. Increasing age was associated with reduced performance across all tasks. Higher educational achievement, the presence of a close confiding relationship, and moderate alcohol intake were associated with benefits across all 4 cognitive tasks, and exercise was associated with better performance on verbal reasoning and verbal working memory tasks. A diagnosis of depression was negatively associated with performance on visual episodic memory and working memory tasks, whereas being underweight negatively affected performance on all tasks apart from verbal working memory. A history of stroke was negatively associated with verbal reasoning and working memory performance. Known modifiable risk factors for dementia are associated with cognitive performance in non-demented individuals in late midlife and older age. This provides further support for public health interventions that seek to manage these risk factors across the lifespan. Copyright © 2017 John Wiley & Sons, Ltd.

Working memory as internal attention: toward an integrative account of internal and external selection processes.

PubMed

Kiyonaga, Anastasia; Egner, Tobias

2013-04-01

Working memory (WM) and attention have been studied as separate cognitive constructs, although it has long been acknowledged that attention plays an important role in controlling the activation, maintenance, and manipulation of representations in WM. WM has, conversely, been thought of as a means of maintaining representations to voluntarily guide perceptual selective attention. It has more recently been observed, however, that the contents of WM can capture visual attention, even when such internally maintained representations are irrelevant, and often disruptive, to the immediate external task. Thus, the precise relationship between WM and attention remains unclear, but it appears that they may bidirectionally impact one another, whether or not internal representations are consistent with the external perceptual goals. This reciprocal relationship seems, further, to be constrained by limited cognitive resources to handle demands in either maintenance or selection. We propose here that the close relationship between WM and attention may be best described as a give-and-take interdependence between attention directed toward either actively maintained internal representations (traditionally considered WM) or external perceptual stimuli (traditionally considered selective attention), underpinned by their shared reliance on a common cognitive resource. Put simply, we argue that WM and attention should no longer be considered as separate systems or concepts, but as competing and influencing one another because they rely on the same limited resource. This framework can offer an explanation for the capture of visual attention by irrelevant WM contents, as well as a straightforward account of the underspecified relationship between WM and attention.

Extensive works have reported that a financial crisis can induce significant changes to topological structure of a stock network constructed with cross-correlations between stocks. But there are still some problems to be answered, such as what is the relationship between different crises in history and how to classify them? In the present work, we propose a new network-based solution to extract and display the relationships between the crises. The Dow Jones stock market is investigated as a typical example. The cross-correlation matrix between stocks is used to measure the state of stock market, called state matrix. All the states cluster into six sub-categories. A state network is constructed further to display the relationships between all the states, which contains a total of nine communities. It is found that three crises C , D and E (refer to the Lehman's bankruptcy in 2008, the Euro-zone and International Monetary Fund decide the first bailout for Greece in 2010, and the European sovereign debt crisis in 2011, respectively) belong to a specific sub-category and cluster in a single community. The mid-stage of C is closely linked with E, while the other stages with D. The other two crises A and B (refer to the financial crisis in Asia in 1997, and the burst of "dot-com bubble" in 2002, respectively) belong to another sub-category and gather in a corner of another single community. A and B are linked directly with C and D by two edges. By this way, we give a clear picture of the relationships between the crises.

In the paper, we are looking at the relationship between globalisation and the professional project, using nursing in Kerala as an exemplar. Our focus is on the intersection of the professional project, gender and globalisation processes. Included in our analysis are the ways in which gender affects the professional project in the global south, and the development of a professional project which it is closely tied to global markets and global migration, revealing the political-economic, historical, and cultural factors that influence the shape and consequences of nurse migration. The phenomenon that enabled our analysis, by showing these forces at work in a particular time and place, was an outbreak of strikes by nurses working in private hospitals in Kerala in 2011-2012.

Quantum-Classical Correspondence Principle for Work Distributions

NASA Astrophysics Data System (ADS)

Jarzynski, Christopher; Quan, H. T.; Rahav, Saar

2015-07-01

For closed quantum systems driven away from equilibrium, work is often defined in terms of projective measurements of initial and final energies. This definition leads to statistical distributions of work that satisfy nonequilibrium work and fluctuation relations. While this two-point measurement definition of quantum work can be justified heuristically by appeal to the first law of thermodynamics, its relationship to the classical definition of work has not been carefully examined. In this paper, we employ semiclassical methods, combined with numerical simulations of a driven quartic oscillator, to study the correspondence between classical and quantal definitions of work in systems with 1 degree of freedom. We find that a semiclassical work distribution, built from classical trajectories that connect the initial and final energies, provides an excellent approximation to the quantum work distribution when the trajectories are assigned suitable phases and are allowed to interfere. Neglecting the interferences between trajectories reduces the distribution to that of the corresponding classical process. Hence, in the semiclassical limit, the quantum work distribution converges to the classical distribution, decorated by a quantum interference pattern. We also derive the form of the quantum work distribution at the boundary between classically allowed and forbidden regions, where this distribution tunnels into the forbidden region. Our results clarify how the correspondence principle applies in the context of quantum and classical work distributions and contribute to the understanding of work and nonequilibrium work relations in the quantum regime.

General Relativistic Precession in Small Solar System Bodies

2016-10-01

Introduction: One of the greatest successes of the Einstein's General Theory of Relativity (GR) was the correct prediction of the precession of perihelion of Mercury. The closed form expression to compute this precession tells us that substantial GR precession would occur only if the bodies have a combination of both moderately small perihelion distance and semi-major axis. Minimum Orbit Intersection Distance (MOID) is a quantity which helps us to understand the closest proximity of two orbits in space. Hence evaluating MOID is crucial to understand close encounters and collision scenarios better. In this work, we look at the possible scenarios where a small GR precession in argument of pericentre (ω) can create substantial changes in MOID for small bodies ranging from meteoroids to comets and asteroids.Analytical Approach and Numerical Integrations: Previous works have looked into neat analytical techniques to understand different collision scenarios and we use those standard expressions to compute MOID analytically. We find the nature of this mathematical function is such that a relatively small GR precession can lead to drastic changes in MOID values depending on the initial value of ω. Numerical integrations were done with package MERCURY incorporating the GR code to test the same effects. Numerical approach showed the same interesting relationship (as shown by analytical theory) between values of ω and the peaks/dips in MOID values. Previous works have shown that GR precession suppresses Kozai oscillations and this aspect was verified using our integrations. There is an overall agreement between both analytical and numerical methods.Summary and Discussion: We find that GR precession could play an important role in the calculations pertaining to MOID and close encounter scenarios in the case of certain small solar system bodies (depending on their initial orbital elements). Previous works have looked into impact probabilities and collision scenarios on planets from different small body populations. This work aims to find certain sub-sets of orbits where GR could play an interesting role. Certain parallels are drawn between the cases of asteroids, comets and small perihelion distance meteoroid streams.

Pressure-Induced Changes in the Structure and Function of the Kinesin-Microtubule Complex

PubMed Central

Nishiyama, Masayoshi; Kimura, Yoshifumi; Nishiyama, Yoshio; Terazima, Masahide

2009-01-01

Kinesin-1 is an ATP-driven molecular motor that “walks” along a microtubule by working two heads in a “hand-over-hand” fashion. The stepping motion is well-coordinated by intermolecular interactions between the kinesin head and microtubule, and is sensitively changed by applied forces. We demonstrate that hydrostatic pressure works as an inhibitory action on kinesin motility. We developed a high-pressure microscope that enables the application of hydrostatic pressures of up to 200 MPa (2000 bar). Under high-pressure conditions, taxol-stabilized microtubules were shortened from both ends at the same speed. The sliding velocity of kinesin motors was reversibly changed by pressure, and reached half-maximal value at ∼100 MPa. The pressure-velocity relationship was very close to the force-velocity relationship of single kinesin molecules, suggesting a similar inhibitory mechanism on kinesin motility. Further analysis showed that the pressure mainly affects the stepping motion, but not the ATP binding reaction. The application of pressure is thought to enhance the structural fluctuation and/or association of water molecules with the exposed regions of the kinesin head and microtubule. These pressure-induced effects could prevent kinesin motors from completing the stepping motion. PMID:19186149

The role of optimization in the next generation of computer-based design tools

There is a close relationship between design optimization and the emerging new generation of computer-based tools for engineering design. With some notable exceptions, the development of these new tools has not taken full advantage of recent advances in numerical design optimization theory and practice. Recent work in the field of design process architecture has included an assessment of the impact of next-generation computer-based design tools on the design process. These results are summarized, and insights into the role of optimization in a design process based on these next-generation tools are presented. An example problem has been worked out to illustrate the application of this technique. The example problem - layout of an aircraft main landing gear - is one that is simple enough to be solved by many other techniques. Although the mathematical relationships describing the objective function and constraints for the landing gear layout problem can be written explicitly and are quite straightforward, an approximation technique has been used in the solution of this problem that can just as easily be applied to integrate supportability or producibility assessments using theory of measurement techniques into the design decision-making process.

Social networking sites (SNS) play an increasingly important role in maintaining geographically close romantic relationships (GCRR). However, knowledge about SNS use in long-distance romantic relationships (LDRR) is still lacking. The present study examined the relative importance of SNS in maintaining LDRR compared to GCRR, particularly with regard to the use of SNS to express involvement (via relational maintenance behaviors) and to gauge a partner's involvement (via partner surveillance and jealousy) in the relationship. An online survey was conducted among predominantly young adult Facebook users who were in a romantic relationship (N=272). Results showed that participants who were in a LDRR reported higher levels of relational maintenance behaviors through SNS than participants who were in a GCRR. Also, as compared to participants who were in a GCRR, participants who were in a LDRR used SNS more for partner surveillance and experienced higher levels of SNS jealousy.

Amylin structure–function relationships and receptor pharmacology: implications for amylin mimetic drug development

PubMed Central

Bower, Rebekah L

2016-01-01

Amylin is an important, but poorly understood, 37 amino acid glucoregulatory hormone with great potential to target metabolic diseases. A working example that the amylin system is one worth developing is the FDA‐approved drug used in insulin‐requiring diabetic patients, pramlintide. However, certain characteristics of pramlintide pharmacokinetics and formulation leave considerable room for further development of amylin‐mimetic compounds. Given that amylin‐mimetic drug design and development is an active area of research, surprisingly little is known about the structure/function relationships of amylin. This is largely due to the unfavourable aggregative and solubility properties of the native peptide sequence, which are further complicated by the composition of amylin receptors. These are complexes of the calcitonin receptor with receptor activity‐modifying proteins. This review explores what is known of the structure–function relationships of amylin and provides insights that can be drawn from the closely related peptide, CGRP. We also describe how this information is aiding the development of more potent and stable amylin mimetics, including peptide hybrids. PMID:27061187

Vacuum effects over the closing of enterocutaneous fistulae: a mathematical modeling approach.

PubMed

Cattoni, D I; Chara, O

2008-01-01

Enterocutaneous fistulae are pathological communications between the intestinal lumen and the abdominal skin. Under surgery the mortality of this pathology is very high, therefore a vacuum applying system has been carried previously on attempting to close these fistulae. The objective of this article is the understanding of how these treatments might work through deterministic mathematical modelling. Four models are here proposed based on several assumptions involving: the conservation of the flow in the fistula, a low enough Reynolds number justifying a laminar flow, the use of Poiseuille law to model the movement of the fistulous liquid, as well as phenomenological equations including the fistula tissue and intermediate chamber compressibility. Interestingly, the four models show fistulae closing behaviour during experimental time (t<60 sec). To compare the models, both, simulations and pressure measurements, carried out on the vacuum connected to the patients, are performed. Time course of pressure are then simulated (from each model) and fitted to the experimental data. The model which best describes actual measurements shows exponential pumping flux kinetics. Applying this model, numerical relationship between the fistula compressibility and closure time is presented. The models here developed would contribute to clarify the treatment mechanism and, eventually, improve the fistulae treatment.

Home-Based Risk of Falling Assessment Test Using a Closed-Loop Balance Model.

The aim of this study is to improve and facilitate the methods used to assess risk of falling at home among older people through the computation of a risk of falling in real time in daily activities. In order to increase a real time computation of the risk of falling, a closed-loop balance model is proposed and compared with One-Leg Standing Test (OLST). This balance model allows studying the postural response of a person having an unpredictable perturbation. Twenty-nine volunteers participated in this study for evaluating the effectiveness of the proposed system which includes seventeen elder participants: ten healthy elderly ( 68.4 ±5.5 years), seven Parkinson's disease (PD) subjects ( 66.28 ±8.9 years), and twelve healthy young adults ( 28.27 ±3.74 years). Our work suggests that there is a relationship between OLST score and the risk of falling based on center of pressure measurement with four low cost force sensors located inside an instrumented insole, which could be predicted using our suggested closed-loop balance model. For long term monitoring at home, this system could be included in a medical electronic record and could be useful as a diagnostic aid tool.

Influence of Hot-Working Conditions on High-Temperature Properties of a Heat-Resistant Alloy

1957-01-01

The relationships between conditions of hot-working and properties at high temperatures and the influence of the hot-working on response to heat treatment were investigated for an alloy containing nominally 20 percent molybdenum, 2 percent tungsten, and 1 percent columbium. Commercially produced bar stock was solution-treated at 2,200 degrees F. to minimize prior-history effects and then rolled at temperatures of 2,200 degrees, 2,100 degrees, 2,000 degrees, 1,800 degrees, and 1,600 degrees F. Working was carried out at constant temperature and with incremental decreases in temperature simulating a falling temperature during hot-working. In addition, a few special repeated cyclic conditions involving a small reduction at high temperature followed by a small reduction at a low temperature were used to study the possibility of inducing very low strengths by the extensive precipitation accompanying such properties. Most of the rolling was done in open passes with a few check tests being made with closed passes. Heat treatments at both 2,050 degrees and 2,200 degrees F. subsequent to working were used to study the influence on response to heat treatment.

The aim was to assess the romantic and peer relationships of bariatric surgery candidates and associations with health behaviors. Adults seeking bariatric surgery (N = 120) completed surveys addressing health behaviors and social relationships at information sessions. Analysis was done to compare male/female differences in peer and romantic relationships and associations with health behaviors. Previously published reference (REF) data on the Relationship Structures questionnaire was used for comparison, and to split our sample into those ≤ or > REF mean for relationship anxiety and avoidance. Our sample reported higher avoidance and lower anxiety in their close friendships and romantic relationships compared to the REF sample. Men in our sample had higher peer and romantic relationships avoidance compared to the REF sample and had significantly higher close friendship avoidance than women in our sample. Participants with lower anxiety in their romantic relationships (≤ REF) had higher uncontrolled eating and physical activity; those with more anxiety in their romantic relationships (> REF) had a higher BMI. Our findings highlight the potential influence that social relationships may have on health behaviors within the bariatric surgery population. Further investigation is warranted to explore male bariatric surgery candidates' relationships to inform understanding and intervention development.

Although premarital heterosexual relationships, especially those involving sexual contact, are discouraged in Iran, particularly for females, a considerable minority of young people are involved in such relationships. However, the determinants of such relationships have not been identified, especially those pertaining to family. In 2005-2006, a random sample of 1,378 unmarried female college students from four universities in Tehran completed anonymous, self-administered surveys that asked whether the respondent had ever had a premarital heterosexual relationship. Bivariate and multivariate regression analyses were conducted to examine associations between such relationships and family factors, including socioeconomic measures, parent-child communication and closeness, family values and atmosphere, and parental control. Having had a boyfriend was positively associated with paternal income (odds ratio, 1.3), maternal educational attainment (1.3) and more liberal family values (1.3), and negatively associated with parent-child closeness (0.6). Very strict and very relaxed parental control during adolescence were both associated with having had a boyfriend, but only the former was associated with having had premarital sex. In addition, respondents were more likely to have had premarital intercourse if they did not live with both parents (2.0) or if their family had more liberal values (1.3); they had reduced odds of having had sex if they had a closer relationship with their parents (0.7). Good family relationships may reduce the likelihood that youth will engage in premarital sex, possibly by fostering parent-child closeness. Moderate parental control may discourage premarital relationships more effectively than lesser or greater degrees of control.

To investigate the relationships between public stigma, stigma by association (SBA), psychological distress, perceived closeness, perceived heredity, and the type of family relationship among family members of people with a mental illness. In this cross-sectional survey, data from 527 family members of people with a mental illness were analyzed. Perceptions of public stigma were found to be positively related to SBA and SBA correlated with greater psychological distress and less perceived closeness. SBA also mediated relationships between perceived public stigma and psychological distress, and between perceived public stigma and perceived closeness. Further, among participants who reported SBA, immediate family members showed lower levels of perceived closeness than extended family members. Also, the perceived heredity of mental illness was associated with perceptions of public stigma and psychological distress. The findings suggest that family members of people with a mental illness could benefit from education on mental illnesses, their treatment, and the extent to which they are hereditary. Additionally, particular attention should be paid to the psychological needs that arise from being a caregiver of someone with a mental illness.

DNA sequences from 28S rDNA were used to assess relationships between and within traditional Taxodiaceae and Cupressaceae s.s. The MP tree and NJ tree generally are similar to one another. The results show that Taxodiaceae and Cupressaceae s.s. form a monophyletic conifer lineage excluding Sciadopitys. In the Taxodiaceae-Cupressaceae s.s. monophyletic group, the Taxodiaceae is paraphyletic. Taxodium, Glyptostrobus and Cryptomeria forming a clade(Taxodioideae), in which Glyptostrobus and Taxodium are closely related and sister to Cryptomeria; Sequoia, Sequoiadendron and Metasequoia are closely related to each other, forming another clade (Sequoioideae), in which Sequoia and Sequoiadendron are closely related and sister to Metasequoia; the seven genera of Cupressaceae s.s. are found to be closely related to form a monophyletic lineage (Cupressoideae). These results are basically similar to analyses from chloroplast gene data. But the relationships among Taiwania, Sequoioideae, Taxodioideae, and Cupressoideae remain unclear because of the slow evolution rate of 28S rDNA, which might best be answered by sequencing more rapidly evolving nuclear genes.

Facilitating Teamwork in Adolescent and Young Adult Oncology

A case of a young adult patient in the days immediately after a cancer diagnosis illustrates the critical importance of three interrelated core coordinating mechanisms—closed-loop communication, shared mental models, and mutual trust—of teamwork in an adolescent and young adult multidisciplinary oncology team. The case illustrates both the opportunities to increase team member coordination and the problems that can occur when coordination breaks down. A model for teamwork is presented, which highlights the relationships among these coordinating mechanisms and demonstrates how balance among them works to optimize team function and patient care. Implications for clinical practice and research suggested by the case are presented. PMID:27624944

Characterizing X-ray Sources in the Rich Open Cluster NGC 7789 Using XMM-Newton

2018-01-01

It is well established that globular clusters exhibit a correlation between their population of exotic binaries and their rate of stellar encounters, but little work has been done to characterize this relationship in rich open clusters. X-ray observations are the most efficient means to find various types of close binaries, and optical (and radio) identifications can provide secure source classifications. We report on an observation of the rich open cluster NGC 7789 using the XMM-Newton observatory. We present the X-ray and optical imaging data, source lists, and preliminary characterization of the sources based on their X-ray and multiwavelength properties.

We review the xanthine oxidase (XO) family of pyranopterin molybdenum enzymes with a specific emphasis on electronic structure contributions to reactivity. In addition to xanthine and aldehyde oxidoreductases, which catalyze the 2-electron oxidation of aromatic heterocycles and aldehyde substrates, this mini-review highlights recent work on the closely related carbon monoxide dehydrogenase (CODH) that catalyzes the oxidation of CO using a unique Mo-Cu heterobimetallic active site. A primary focus of this mini-review relates to how spectroscopy and computational methods have been used to develop an understanding of critical relationships between geometric structure, electronic structure, and catalytic function.

A SAT Based Effective Algorithm for the Directed Hamiltonian Cycle Problem

NASA Astrophysics Data System (ADS)

Jäger, Gerold; Zhang, Weixiong

The Hamiltonian cycle problem (HCP) is an important combinatorial problem with applications in many areas. While thorough theoretical and experimental analyses have been made on the HCP in undirected graphs, little is known for the HCP in directed graphs (DHCP). The contribution of this work is an effective algorithm for the DHCP. Our algorithm explores and exploits the close relationship between the DHCP and the Assignment Problem (AP) and utilizes a technique based on Boolean satisfiability (SAT). By combining effective algorithms for the AP and SAT, our algorithm significantly outperforms previous exact DHCP algorithms including an algorithm based on the award-winning Concorde TSP algorithm.

Physical and perceptual estimation of differences between loudspeakers

2006-12-01

Differentiating the restitution of timbre by several loudspeakers may result from standard measurements, or from listening tests. This work proposes a protocol keeping a close relationship between the objective and perceptual evaluations: the stimuli are musical excerpts, and the measuring environment is a standard listening room. The protocol involves recordings made at a listener position, and objective dissimilarities are computed using an auditory model simulating masking effects. The resulting data correlate very well with listening tests using the same recordings, and show similar dependencies on the major parameters identified from the dissimilarity matrices.

2010-01-01

The aim of the present study was to examine the relation of insomnia with job stress factors, stress response, and social support. A self-completed questionnaire survey was conducted in 212 male Japanese workers at a synthetic fiber plant. With regard to insomnia, subjects were asked the first 5 of the 8 questions on the Athens Insomnia Scale (AIS). Job stress factors, stress response and social support were assessed using the Job Stress Questionnaire. Multiple regression analyses showed that psychological job stress factors of poor appropriateness of work and high qualitative workload were associated with insomnia. The psychological stress response of depression and physical stress responses were also related with insomnia. Depression was also related to appropriateness of work. The present results showed that insomnia was closely related with the psychological job stress factor of appropriateness of work and the psychological response of depression. These mutual relationships between insomnia and poor mental health need be investigated further.

Social support at work is considered useful in treating job-related stress, and supervisors' emotional support has been found to be the most effective source of support at work. But an understanding of what elements make employees use supervisors as a source of emotional support is lacking. The present qualitative study included in-depth interviews with 24 teachers and 12 principals and a focus group with 12 school counsellors. The findings pointed at 2 groups of determinants of subordinates' intentions of asking socioemotional help from supervisors. The structural-organizational factors included low formalization structure, supportive and open work climate, shared goals, and manager's professional expertise; the dyadic factors included quality of relationship and demographic similarity. The determinants reflected different dimensions of psychological distance forming a close construal level that played a central part in employees' viewing the supervisor as an accessible socioemotional resource. The role of construal fit is discussed. Copyright © 2018 John Wiley & Sons, Ltd.

Part of the works were compiled by his disciples, while others were by his self-taught followers based on prior circulated Danxi's originals, plus some apocryphal so-called Danxi's works circulated posthumously. When sorting out Danxi's Hand Mirror, we found that some of its contents are closely related to Bei ji qian jin yao fang (Essential Prescriptions Worth a Thousand Gold for Emergencies), Qian jin yi fang (Supplements to Qian jin yao fang), Tai ping sheng hui fang (Peaceful Holy Benevolent Prescriptions), Zhu jie shang han lun (Annotated Treatises of Cold Pathogenic Disease), Shang han ming li lun (Elucidation of Cold Pathogenic Disease), Ge zhi yu lun (Treatise of Inquiring the Properties of Things), either by transcription or with an identical origin. By clearing their relationships, it can provide assistance to the research of the philological structure of Danxi's hand Mirror.

Pregnant and parenting adolescents and their younger sisters: the influence of relationship qualities for younger sister outcomes.

PubMed

East, P L; Shi, C R

1997-04-01

On the basis of social modeling theory and a sibling interaction hypothesis, it was hypothesized that specific relationship qualities between a pregnant or parenting teen and her younger sister would be associated with permissive younger sister outcomes, such as permissive childbearing attitudes and permissive sexual behavior. Results indicated that negative relationship qualities, such as rivalry, competition, and conflict, were more closely related to younger sisters engaging in problem delinquent-like behavior and sexual behavior than were positive relationship qualities, such as warmth and closeness. Additionally, a shared friendship network with the older sister was found to be associated with extensive younger sister problem behavior and sexual behavior. Three potential explanatory processes are discussed.

The dependency paradox in close relationships: accepting dependence promotes independence.

PubMed

Feeney, Brooke C

2007-02-01

Using multiple methods, this investigation tested the hypothesis that a close relationship partner's acceptance of dependence when needed (e.g., sensitive responsiveness to distress cues) is associated with less dependence, more autonomous functioning, and more self-sufficiency (as opposed to more dependence) on the part of the supported individual. In two studies, measures of acceptance of dependency needs and independent functioning were obtained through couple member reports, by observing couple members' behaviors during laboratory interactions, by observing responses to experimentally manipulated partner assistance provided during an individual laboratory task, and by following couples over a period of 6 months to examine independent goal striving as a function of prior assessments of dependency acceptance. Results provided converging evidence in support of the proposed hypothesis. Implications of the importance of close relationships for optimal individual functioning are discussed.

Empirically based couple therapy results in significant improvements in relationship satisfaction for the average couple; however, further research is needed to identify mediators that lead to change and to ensure that improvements in mediators predict subsequent-not just concurrent-relationship satisfaction. In addition, given that much of the current literature on couple therapy examines outcomes in a research environment, it is important to examine mediators in a treatment-as-usual setting. To address these questions, 161 heterosexual couples (322 individuals) received treatment-as-usual couple therapy at one of two Veteran Administration Medical Centers (M = 5.0 and 13.0 sessions at the two sites) and were assessed before every session. The majority of couples were married (85%) and had been together for a median of 7.8 years (SD = 13). Participants were primarily White, non-Hispanic (69%), African American (21%), and White, Hispanic/Latino (8%). Individuals' own self-reported improvements in communication, emotional closeness, and psychological distress (but not frequency of behaviors targeted in treatment) mediated the effect of treatment on their subsequent relationship satisfaction. When all significant mediators were examined simultaneously, improvements in men's and women's emotional closeness and men's psychological distress independently mediated subsequent relationship satisfaction. In contrast, improvements in earlier relationship satisfaction mediated the effect of treatment only on subsequent psychological distress. This study identifies unique mediators of treatment effects and shows that gains in mechanisms predict subsequent relationship satisfaction. Future investigations should focus on the role of emotional closeness and psychological distress-constructs that have often been neglected-in couple therapy.

Available means: manifestations of Aristotle's three modes of rhetorical appeal in antinuclear fiction

DOE Office of Scientific and Technical Information (OSTI.GOV)

Mannix, P.J.

1986-01-01

The abundance of sympathetic scientists, military men and clergymen in antinuclear fiction reflects a public perception that authorities speak most knowledgeably about an issue. Other antinuclear works employ characters with less traditional ethical appeals: nurturing women, vital youths, and even infallible computers. Antinuclear fiction uses enthymeme and example to reflect the history of the nuclear weapons debate. Some works attach the immorality of the weapons by examining the moral dilemmas of nuclear scientists. Others admit the permanence of the nuclear threat. By arousing emotions, fiction is capable of mobilizing its audience's active support for the ideas it presents. The principalmore » emotions that various antinuclear works arouse highlight the close relationship between literature and rhetoric. The most dominant emotions, pity and fear, are the two Aristotle links to tragedy. Scorn, the principal emotion that Dr. Strangelove arouses - is the crucial emotion on which all satire depends. However, the other principal emotion in anti-nuclear fiction - hope - has principally a rhetorical function ensuring that the feelings the works provoke will be channeled constructively.« less

A medieval physician: Amirdovlat Amasiatsi (1420-1495).

Gurunluoglu, Aslin; Gurunluoglu, Raffi; Hakobyan, Tatevik

2016-01-01

We aimed to acquaint the reader with a medieval physician, Amirdovlat Amasiatsi, who lived and practiced in the 15th century Anatolia. Amirdovlat wrote several books on medicine mainly focusing on phytotherapy and pharmacology using medicinal plants, animal-derived products and minerals. All his works were written in Middle Armenian, spoken Armenian language of the time. In his writings, Amirdovlat described unique recipes that represent a portrayal of medical knowledge and practice at the time in Anatolia where he lived and worked. He discussed the physical and therapeutic properties as well as geographic distributions of various plants and minerals, using different languages, mainly Turkish, Greek, Arabic, French and Persian. Amirdovlat's works not only enhanced our understanding of Armenian medical practices but also provided great deal of information on those of Ancient Greco-Roman as well as Islamic world, demonstrating close relationship of Armenian medicine with Greco-Roman and Islamic medicine. Amirdovlat accomplished this by amalgamating the past and contemporary practices of his time. In this regard, Amirdovlat's works, in particular "Useless for the Ignorant", are very unique playing a significant role in preserving traditions and heritage of different cultures.

The aim of this work was to examine the evolution and potential existence of intragenic recombinations of PRRSV strains in Sonora, Mexico. In this study, 142 serum samples from farms located in Hermosillo (HMO), Cd. Obregón (OBR) and Navojoa (NAV) were sequenced from 2002 to 2012. Ninety non-redundant sequences of ORF5 gene were analyzed for temporal and spatial relationships among strains and the probability of a recombination event. The phylogenetic analysis showed 30 strains grouped into eight groups; 16 strains were closely related among the farms, while 14 were un-related. The first strain in this study was observed in 2002. A number of farms were infected with one or more strains, and in the majority of the strains, the virus was replaced by a new strain. The recombination analysis suggested the presence of four viruses as products of a recombination event; in one case, a virus close related with MLV vaccine was involved as the parent virus. This work shows the evolution of PRRSV in the field, the viral dissemination between farms and the potential recombination events. Our data suggest that PRRSV in Sonora has a specific genetic nature compared with other PRRSV. Copyright © 2014 Elsevier B.V. All rights reserved.

Brain activity underlying negative self- and other-perception in adolescents: The role of attachment-derived self-representations.

One of teenagers' key developmental tasks is to engage in new and meaningful relationships with peers and adults outside the family context. Attachment-derived expectations about the self and others in terms of internal attachment working models have the potential to shape such social reorientation processes critically and thereby influence adolescents' social-emotional development and social integration. Because the neural underpinnings of this developmental task remain largely unknown, we sought to investigate them by functional magnetic resonance imaging. We asked n = 44 adolescents (ages 12.01-18.84 years) to evaluate positive and negative adjectives regarding either themselves or a close other during an adapted version of the well-established self-other trait-evaluation task. As measures of attachment, we obtained scores reflecting participants' positive versus negative attachment-derived self- and other-models by means of the Relationship Questionnaire. We controlled for possible confounding factors by also obtaining scores reflecting internalizing/externalizing problems, schizotypy, and borderline symptomatology. Our results revealed that participants with a more negative attachment-derived self-model showed increased brain activity during positive and negative adjective evaluation regarding the self, but decreased brain activity during negative adjective evaluation regarding a close other, in bilateral amygdala/parahippocampus, bilateral anterior temporal pole/anterior superior temporal gyrus, and left dorsolateral prefrontal cortex. These findings suggest that a low positivity of the self-concept characteristic for the attachment anxiety dimension may influence neural information processing, but in opposite directions when it comes to self- versus (close) other-representations. We discuss our results in the framework of attachment theory and regarding their implications especially for adolescent social-emotional development and social integration.

To investigate health professionals' evaluation of a computer-based resource designed to improve discussions about sexual and relationship health with young people. Evidence suggests that some health professionals can experience discomfort discussing sexual health and relationship issues with young people. Professionals within hospital settings should have the knowledge, competencies and skills to be able to ask young people sexual health questions and provide accurate sexual health education. Despite some educational material being available for community and adult services, there are no resources available, which are directly relevant to holding opportunistic discussions with young people within an acute children's hospital. A descriptive survey design. One hundred and fourteen health professionals from a children's hospital in the UK were involved in evaluating a computer-based resource. All completed an online questionnaire survey comprising of closed and open questions. The health professionals reported that the computer-based resource had a positive influence on their knowledge and clinical practice. The videos as well as the concise nature of the resource were evaluated highly. Learning was facilitated by professionals being able to control their learning through rerunning and accessing the resource on numerous occasions. An engaging, accessible computer-based resource has the capability to positively impact on health professionals' knowledge of, and skills in, starting and holding sexual health conversations with young people accessing a children's hospital. Health professionals working with children and young people value accessible, relevant and short computer-based training. This can facilitate knowledge and skill acquisition despite variation in working patterns. Improving the knowledge and skills of professionals working with young people to facilitate appropriate yet opportunistic sexual health discussions is important within the public health agenda. © 2013 John Wiley & Sons Ltd.

The role of the faculty mentor to the REU experience: insights from an international REU

Houser, C.; Cahill, A. T.; Lemmons, K.

2012-12-01

The Texas A&M REU in Costa Rica provides students with an opportunity to participate in research on the ecohydrology of a tropical pre-montane forest. The international and field components of this program require both that students to work in research clusters of several faculty and students, and that each of the clusters contribute to a primary research question of closing the water budget for a small watershed. Specifically, students and faculty participate in precipitation (P), evapotranspiration (E), hydrology (Q) or subsurface storage (DS) research clusters. It is argued that having the students at a central research station location and focusing their research on a common research problem is an important aspect of an international REU program to avoid a feeling of isolation and to ensure that the students remain safe in their research and during their free time. However, this shared experience and research question can highlight differences among the faculty mentors and make the students evaluate their individual experience more critically. To better understand the relationship between the REU student and their faculty mentor(s), we have been conducting pre- and post-surveys, interviews, and focus groups to understand their experience in the REU and the manner in which the faculty mentor can affect that experience and the desire to continue in research. Results of the pre-trip survey suggest that the undergraduate students are most concerned about their projects and show little no concern about the faculty mentor with whom they will be completing their research. Post-trip results from 2011 and 2012 suggest that mentors had a much greater impact on the experience than expected. Many students said that their future research/graduate school plans were significantly affected by their REU mentor relationship. One student said that by working closely with mentors, "you know that what you are doing and learning is pertinent because you are learning it from actual researchers." The overall results suggest that the student-to-mentor relationship created through these authentic experiences is highly influential in either encouraging or discouraging students to conduct future research and/or attend graduate school.

The reasons for the high prevalence of depressive disorders in women of Pakistani origin living in the UK are not clear. The aim of this study was to determine the relative importance of life events, chronic social difficulties and acculturation in a population-based sample of British Pakistani women. A cross-sectional and prospective cohort study of 18- to 65-year-old Pakistani women in UK was carried out. The Schedule for Clinical Assessment in Neuropsychiatry for diagnosis, the Life Events and Difficulties Schedule for social stress and an acculturation questionnaire were used. Depressive disorder at baseline was associated with older age, social isolation and marked difficulties involving health and close relationships. Depressive disorder at follow-up was associated with severity of depression at baseline, difficulties in close relationships and two aspects of acculturation, especially less acculturation in relation to use of the English language. Lack of acculturation, especially less familiarity with the English language, is an independent predictor of persistence of depression in Pakistani women in UK. This needs to be taken into consideration when planning treatment, which also needs to address the personal difficulties associated with persistent depression. The implication of this work is that women of Pakistani origin with depression should be encouraged to receive help in the use of English as one part of treatment that may prevent relapse.

Comparison of connectivity analyses for resting state EEG data

2017-06-01

Objective. In the present work, a nonlinear measure (transfer entropy, TE) was used in a multivariate approach for the analysis of effective connectivity in high density resting state EEG data in eyes open and eyes closed. Advantages of the multivariate approach in comparison to the bivariate one were tested. Moreover, the multivariate TE was compared to an effective linear measure, i.e. directed transfer function (DTF). Finally, the existence of a relationship between the information transfer and the level of brain synchronization as measured by phase synchronization value (PLV) was investigated. Approach. The comparison between the connectivity measures, i.e. bivariate versus multivariate TE, TE versus DTF, TE versus PLV, was performed by means of statistical analysis of indexes based on graph theory. Main results. The multivariate approach is less sensitive to false indirect connections with respect to the bivariate estimates. The multivariate TE differentiated better between eyes closed and eyes open conditions compared to DTF. Moreover, the multivariate TE evidenced non-linear phenomena in information transfer, which are not evidenced by the use of DTF. We also showed that the target of information flow, in particular the frontal region, is an area of greater brain synchronization. Significance. Comparison of different connectivity analysis methods pointed to the advantages of nonlinear methods, and indicated a relationship existing between the flow of information and the level of synchronization of the brain.

Thorsen, Maggie L.; Amato, Paul R.

2014-01-01

This study employs nationally representative data on adolescents and their stepfathers (n = 2085) from the National Longitudinal Study of Adolescent Health (Add Health) to examine factors associated with positive stepfather-stepchild relationships in married stepfamilies. Results reveal substantial variability in the perceived quality of adolescents’ relationships with stepfathers. Structural equation models using Wave I data reveal that close relationships with mothers and close ties between mothers and stepfathers are positively related to the perceived quality of adolescents’ relationships with stepfathers. Longitudinal models using Waves I and II do not yield definitive results but suggest that the direction of influence runs in both directions, with the mother-child relationship and the stepfather-stepchild relationship mutually reinforcing one another. We identify a number of other factors that are associated with positive stepfather-stepchild ties, as well as a few factors that may be less consequential than previously thought. Most of the correlates of positive stepfather-stepchild relationships are similar for boys and girls; for Whites, Blacks, and Hispanics; and for stepfamilies of various durations. PMID:24913942

AIM—To determine the relation of refractive error to environmental factors, including close up work, in Singapore military conscripts.
METHODS—A cross sectional study was conducted on 429 Singapore military conscripts. Non-cycloplegic refraction and A-scan biometry were performed in both eyes. A detailed questionnaire was administered by in-person interview to obtain information about current and past near work activity, extra tuition lessons, educational experiences, and family demographics.
RESULTS—Myopia associated with the conscript having been educated in the (gifted, special, or express) educational streams (adjusted odds ratio (OR) = 3.8, 95% confidence interval CI 2.0-7.3), and having completed pre-university education (OR=4.1, 95% CI 1.9-8.8). The reported close up work activity at age 7 years did correlate with age of onset of myopia (p<0.001). In parallel, supplemental tuition lessons in primary school has (OR=2.6, 95% CI 1.4-4.9) associated with conscript myopia. Parental myopia was positively associated with myopia (p<0.001), but this relation disappeared when adjusted for environmental factors. Current (p=0.83) and past close up work activity at age 7 years (p=0.13) did not correlate with myopia.
CONCLUSION—Educational level and educational stream positively related to myopia. A relation was observed with reported close up work activity in early childhood and with tuition classes during elementary school, but not with current close up work activity. These results underscore the strong influence of environment in myopia pathogenesis but a role for close up work activity remains indeterminate.

'Everything contradicts in your mind': a qualitative study of experiences of forensic mental health staff in two contrasting services.

 In the theoretical literature, there is growing recognition of the psychological impact on staff of working in challenging healthcare settings. In forensic mental health (FMH) services, powerful transference and counter-transference reactions in staff-patient relationships may emerge and may even play a role in contributing to incidents of malpractice, but there is little empirical research here.  The exploration of the experiences of FMH staff in two contrasting services.  Thirteen in-depth interviews were carried out with staff from a range of clinical disciplines in a mainstream National Health Service (NHS) medium secure unit (MSU), and 12 interviews were undertaken with such staff from a Personality Disorder Unit (PDU) in an MSU. All interview data were analysed independently using the grounded theory method. To synthesise the two separate analyses, a thematic analysis of both data sets was carried out, in which 'thematic units' were defined as significant points of comparison between the analyses of the two sets of interviews.  The combined analysis yielded six main themes under two main headings. Themes under the first heading Experience of the Clinical Task were: 'difficulty in achieving task integration'; 'motivation to build relationships, work through difficulty and bring about change'; and 'minimal sense of risk and anxiety at the centre'. Themes under the second heading Experience of the Organisation were: 'a distant and difficult relationship with outside'; 'preoccupation with staff relationships'; and 'feeling unsafe'. The overarching concept of the combined analysis was encapsulated in the quotation: 'Everything contradicts in your mind'.  Clinical and organisational aspects of work seemed separate in the minds of staff, with the latter reported to be more stressful; staff support came in the form of close relationships with colleagues, who saw themselves as isolated in the context of the wider environment. Promotion of the well-being and effectiveness of FMH staff should therefore take account of clinical, organisational and societal aspects of their situation. 2011 John Wiley & Sons, Ltd.

This study explored how teacher-child relationships change over the early school years, in terms of closeness and conflict, whether these trajectories differ in type and frequency for children with typical development and children with speech and language concern (SLC), and whether the trajectories are associated with school outcomes at 12-13 years. Participants were children, parents and teachers in the Longitudinal Study of Australian Children. Parents identified 2890 children with typical communication and 1442 children with SLC. Teacher-rated teacher-child closeness and conflict were collected biennially over six years. Academic and social-emotional outcomes were reported by teachers and children. Growth mixture modelling was conducted to generate teacher-child relationship trajectories and Wald's chi-square analyses were used to test the association between trajectories and school outcomes at 12-13 years, after controlling for a range of covariates including child's sex, language background, Indigenous status, age and socio-economic position. In both groups, the majority of children had teacher-child relationship trajectories with sustained high closeness and low conflict that predicted positive outcomes at age 12-13, but the SLC group was more at risk of less positive trajectories and poorer school outcomes. Close, less conflicted relationships with teachers may provide a supportive context for later language, literacy and social-emotional development. This study highlights the role of teachers in supporting children in their development of communication and academic skills that will optimise their capacity for freedom of opinions and expression, education and participation, as enshrined in Articles 19, 26 and 27 of the Universal Declaration of Human Rights.

Enhanced dimension-specific visual working memory in grapheme-color synesthesia.

Terhune, Devin Blair; Wudarczyk, Olga Anna; Kochuparampil, Priya; Cohen Kadosh, Roi

2013-10-01

There is emerging evidence that the encoding of visual information and the maintenance of this information in a temporarily accessible state in working memory rely on the same neural mechanisms. A consequence of this overlap is that atypical forms of perception should influence working memory. We examined this by investigating whether having grapheme-color synesthesia, a condition characterized by the involuntary experience of color photisms when reading or representing graphemes, would confer benefits on working memory. Two competing hypotheses propose that superior memory in synesthesia results from information being coded in two information channels (dual-coding) or from superior dimension-specific visual processing (enhanced processing). We discriminated between these hypotheses in three n-back experiments in which controls and synesthetes viewed inducer and non-inducer graphemes and maintained color or grapheme information in working memory. Synesthetes displayed superior color working memory than controls for both grapheme types, whereas the two groups did not differ in grapheme working memory. Further analyses excluded the possibilities of enhanced working memory among synesthetes being due to greater color discrimination, stimulus color familiarity, or bidirectionality. These results reveal enhanced dimension-specific visual working memory in this population and supply further evidence for a close relationship between sensory processing and the maintenance of sensory information in working memory.

Constructing the truth: from 'confusion of tongues' to 'constructions in analysis'.

PubMed

Press, Jacques

2006-04-01

The author hypothesizes that the papers Freud wrote in the period 1934-9 constitute a final turning point in his work resulting from an attempt to work through, by means of self-analysis, early traumatic elements reactivated by the conditions of his life in the 1930s. The author emphasizes that the ups and downs of Freud's relationship with Sándor Ferenczi and the mourning which followed his death in 1933 played an important role in this traumatic situation. He suggests that through these last works, Freud pursued a posthumous dialogue with Ferenczi. This working through led Freud, in Moses and monotheism, to an ultimate revision of his theory of trauma, a revision which the author examines in full, in the light of the works of the Egyptologist, Jan Assmann. A new analytical paradigm emerges: that of constructions in analysis developed in the article of the same name. The activity of construction appears as an alternative to the mutual analysis proposed by Ferenczi and is closely bound up with the notion of historical truth. In psychoanalysis, it would mean constructing a historical truth whose anchoring in the material truth of the past is essential, though it should not be confused with it.

Jet engine noise and infrared plume correlation field campaign

Jet engine noise can be a health hazard and environmental pollutant, particularly affecting personnel working in close proximity to jet engines, such as airline mechanics. Mitigating noise could reduce the potential for hearing loss in runway workers; however, there exists a very complex relationship between jet engine design parameters, operating conditions, and resultant noise power levels, and understanding and characterizing this relationship is a key step in mitigating jet engine noise effects. We demonstrate initial results highlighting the utility of high-speed imaging (hypertemporal imaging) in correlating the infrared signatures of jet engines with acoustic noise. This paper builds on prior theoretical analysis of jet engine infrared signatures and their potential relationships to jet engine acoustic emissions. This previous work identified the region of the jet plume most likely to emit both in infrared and in acoustic domains, and it prompted the investigation of wave packets as a physical construct tying together acoustic and infrared energy emissions. As a means of verifying these assertions, a field campaign to collect relevant data was proposed, and data collection was carried out with a bank of infrared instruments imaging a T700 turboshaft engine undergoing routine operational testing. The detection of hypertemporal signatures in association with acoustic signatures of jet engines enables the use of a new domain in characterizing jet engine noise. This may in turn enable new methods of predicting or mitigating jet engine noise, which could lead to socioeconomic benefits for airlines and other operators of large numbers of jet engines.

Disparities in Social Health by Sexual Orientation and the Etiologic Role of Self-Reported Discrimination

2015-01-01

Some past work indicates that sexual minorities may experience impairments in social health, or the perceived and actual availability and quality of one’s social relationships, relative to heterosexuals; however, research has been limited in many ways. Furthermore, it is important to investigate etiological factors that may be associated with these disparities, such as self-reported discrimination. The current work tested whether sexual minority adults in the United States reported less positive social health (i.e., loneliness, friendship strain, familial strain and social capital) relative to heterosexuals and whether self-reported discrimination accounted for these disparities. Participants for the current study (N = 579) were recruited via Amazon’s Mechanical Turk, including 365 self-identified heterosexuals (105 women) and 214 sexual minorities (103 women). Consistent with hypotheses, sexual minorities reported impaired social health relative to heterosexuals, with divergent patterns emerging by sexual orientation subgroup (which were generally consistent across sexes). Additionally, self-reported discrimination accounted for disparities across three of four indicators of social health. These findings suggest that sexual minorities may face obstacles related to prejudice and discrimination that impair the functioning of their relationships and overall social health. Moreover, because social health is closely related to psychological and physical health, remediating disparities in social relationships may be necessary to address other health disparities based upon sexual orientation. Expanding upon these results, implications for efforts to build resilience among sexual minorities are discussed. PMID:26566900

Learning Quantitative Sequence-Function Relationships from Massively Parallel Experiments

Atwal, Gurinder S.; Kinney, Justin B.

2016-03-01

A fundamental aspect of biological information processing is the ubiquity of sequence-function relationships—functions that map the sequence of DNA, RNA, or protein to a biochemically relevant activity. Most sequence-function relationships in biology are quantitative, but only recently have experimental techniques for effectively measuring these relationships been developed. The advent of such "massively parallel" experiments presents an exciting opportunity for the concepts and methods of statistical physics to inform the study of biological systems. After reviewing these recent experimental advances, we focus on the problem of how to infer parametric models of sequence-function relationships from the data produced by these experiments. Specifically, we retrace and extend recent theoretical work showing that inference based on mutual information, not the standard likelihood-based approach, is often necessary for accurately learning the parameters of these models. Closely connected with this result is the emergence of "diffeomorphic modes"—directions in parameter space that are far less constrained by data than likelihood-based inference would suggest. Analogous to Goldstone modes in physics, diffeomorphic modes arise from an arbitrarily broken symmetry of the inference problem. An analytically tractable model of a massively parallel experiment is then described, providing an explicit demonstration of these fundamental aspects of statistical inference. This paper concludes with an outlook on the theoretical and computational challenges currently facing studies of quantitative sequence-function relationships.

Proton channel models

2014-01-01

Voltage-gated proton channels are integral membrane proteins with the capacity to permeate elementary particles in a voltage and pH dependent manner. These proteins have been found in several species and are involved in various physiological processes. Although their primary topology is known, lack of details regarding their structures in the open conformation has limited analyses toward a deeper understanding of the molecular determinants of their function and regulation. Consequently, the function-structure relationships have been inferred based on homology models. In the present work, we review the existing proton channel models, their assumptions, predictions and the experimental facts that support them. Modeling proton channels is not a trivial task due to the lack of a close homolog template. Hence, there are important differences between published models. This work attempts to critically review existing proton channel models toward the aim of contributing to a better understanding of the structural features of these proteins. PMID:24755912

Making space for the inner guide.

PubMed

Leijssen, Mia

2007-01-01

The therapeutic relationship is described as a curative factor in its own right as well as facilitative for other tasks. Experiential tasks that facilitate working on the intrapsychic, interpersonal, and existential domains are distinguished. Focusing is an intrapsychic task of paying attention to one's bodily felt experience. Clearing space helps clients finding a right distance for exploring their experience when they are too close or too distanced from their emotions. Interpersonal work takes the lead when maladaptive interactional patterns are hindering the relational life of the client. Metacommunicative feedback and interpersonal experiences in the therapeutic encounter act as an invitation to develop new ways of communicating. Existential processes are challenged when the client struggles with the givens of life. Finally, the "inner guide" found in accessing experiencing may involve an awareness of a transcendent dimension that leads one to spiritual growth. Vignettes from short term psychotherapy illustrate how this approach is established in practice.

Ethical and methodological issues in academic mental health research in populations affected by disasters: the Oklahoma City experience relevant to September 11, 2001.

Empirical data from research studies are vital to guiding mental health interventions following disasters. However, few data are available for this purpose. Important advances in policy and procedures for the conduct of organized research emerged from the Oklahoma City bombing, yielding cooperative working relationships among researchers and culminating in the ethical attainment of informative research data. However, the academic community was again caught off guard after the September 11, 2001, terrorist attacks. Suggestions to surmount these obstacles include incorporating research infrastructures into disaster preparedness plans in advance; organizing the community of researchers; and working closely with major funding organizations. Methodological issues pertaining to measurement of psychopathology include the importance of obtaining diagnostic data; interpreting the meaning of symptoms in the absence of a psychiatric disorder; differentiating preexisting symptoms from those that emerged after the disaster, and optimal timing of postdisaster assessment.

The new millennium program: Fast-track procurements

The National Aeronautics and Space Administration's (NASA's) New Millennium Program (NMP) has embarked on a technology flight-validation demonstration program to enable the kinds of missions that NASA envisions for the 21st century. Embedded in this program is the concept of rapid mission development supported by a fast-track procurement process. This process begins with the decision to initiate a procurement very early in the program along with the formation of a technical acquisition team. A close working relationship among the team members is essential to avoiding delays and developing a clear acquisition plan. The request for proposal (RFP) that is subsequently issued seeks a company with proven capabilities, so that the time allotted for responses from proposers and the length of proposals they submit can be shortened. The fast-track procurement process has been demonstrated during selection of NMP's industrial partners and has been proven to work.

Sustaining NGOs in the developing world: a perspective from the developing world.

Damodaran, A

1993-01-01

The issue of sustainable development is attracting a lot of attention in the 1990s in the developing world. The author therefore draws upon experience from India, Nepal, and Bangladesh to consider the related issue of sustaining nongovernmental organizations (NGO) in developing countries. Vision, credibility and trust, stable management, pragmatic leadership, good staff, team work, and public accountability are called for to develop and maintain a successful NGO. Further, pre-project studies, realistic budgeting, time frame, relationship between funding agency and NGO, multi-source funding, flexibility, scaling up, and resource mobilization are issues with which NGOs reckon throughout the world. Some criteria for financial sustainability, however, are strongly influenced by conditions and experiences particular to developing countries. In closing, the author stresses that NGOs working with the very poor must strive to sustain any process of social change leading toward community empowerment and social justice.

To determine the correlation between the working environment and the health status of employees in solar greenhouse, 1171 employees were surveyed. The results show the 'Greenhouse diseases' are affected by many factors. Among general uncomforts, the morbidity of the bone and joint damage is the highest and closely related to labor time and age. Planting summer squash and wax gourd more easily cause skin pruritus. Asthma-related cough, eye disease, and skin pruritus are significantly correlated with the cultivation of wax gourd. The application of inorganic fertilizer and fertigation dramatically induce the bone and joint damage. The smell of covering film greatly influence skin pruritus. Personal protection is badly scanty and normative occupational health and safety need to be completed. Copyright © 2015 The Editorial Board of Biomedical and Environmental Sciences.

A concerted effort has been underway over the past several years to evolve computational capabilities for modeling aircraft loss-of-control under the NASA Aviation Safety Program. A principal goal has been to develop reliable computational tools for predicting and analyzing the non-linear stability & control characteristics of aircraft near stall boundaries affecting safe flight, and for utilizing those predictions for creating augmented flight simulation models that improve pilot training. Pursuing such an ambitious task with limited resources required the forging of close collaborative relationships with a diverse body of computational aerodynamicists and flight simulation experts to leverage their respective research efforts into the creation of NASA tools to meet this goal. Considerable progress has been made and work remains to be done. This paper summarizes the status of the NASA effort to establish computational capabilities for modeling aircraft loss-of-control and offers recommendations for future work.

Most people need to be cared for at the end of their lives by professionals. This study aimed to elucidate the meaning of nurses' experiences of caring for dying persons at home and in a special unit in a hospital. Four registered nurses working in private homes and 4 registered nurses working in a specific unit in a hospital setting were interviewed. The study was planned and carried out with a phenomenological hermeneutic approach. A naive reading guided a structural analysis, which resulted in 3 main themes: meeting patients and family members as unique persons, learning in a challenging environment, and gaining personal strength. The interpreted comprehensive understanding conveyed a meaning that caring for families with a member awaiting the end of life created a situation where the presence of an inevitable death demanded nurses to create close relationships with each unique person involved.

2015-01-01

This study examined adolescents’ ability to utilize emotional repair—to actively change negative moods to more positive moods—as a predictor of the quality of their developing peer and romantic relationships over time. Utilizing observational data and partners’ reports, adolescents (N = 184), their close peers, and their romantic partners were followed from ages 15–19. Adolescents with initially stronger emotional repair abilities were rated as increasingly socially competent over time, and both displayed and experienced increasingly positive interactive behaviors with close peers over time. These adolescents’ romantic partners also reported more positive relationships, with enhanced communication, and fewer critical, blaming, or hostile interactions. Implications for the role of emotional repair abilities in the development of successful relationships during adolescence are discussed. PMID:28042228

A narrative review of the major evidence concerning the relationship between anxiety, social support and cardiac disease was conducted. Literature demonstrates that a strict relationship between anxiety, social support and cardiac disease outcomes subsists. However, the function of social support within anxiety and heart disease association remains unclear and needs to further researches to be established. Moreover evidence suggests that it’s the quality of close relationships to play an important role in affecting psychological and physiological health status. The main components that the literature suggests for a better quality of social support and close relationship, and the main assessment measure are presented. Evidence about cardiac rehabilitation programs and the need to assess and intervene on psychological and psychosocial factors is discussed. PMID:24403952

A developing literature continues to testify to the relationship between higher socio-economic status (SES) and better academic attainment. However, the literature is complex in terms of the variety of SES and attainment indicators used. Against the backdrop of a Scottish Government initiative to close the attainment gap between higher and lower SES children, the present study examined the relationship between individual-level Scottish Index of Multiple Deprivation (SIMD) and National Lower Tariff Score in school children in the West of Scotland. Results showed a practically significant relationship between SIMD and Tariff Score. This relationship was partially mediated by higher academic self-efficacy, so that higher belief in academic competency partially mediated the SIMD-Tariff Score relationship. Further, this partial mediation was robust to the influence of gender, sensation seeking, level of school attendance and past month frequency of Heavy Episodic Drinking. It is suggested that increasing attendance and perceived academic competence are viable ways (among others) of attempting to close the attainment gap.

The relationships between atopy, rhinitis and asthma: pathophysiological considerations.

PubMed

Boulay, Marie-Eve; Boulet, Louis-Philippe

2003-02-01

A close relationship has been described between atopy, allergic rhinitis and asthma. The purpose of this work was to review recent data that have become available on the interactions between these conditions and the ways in which they influence one another. Recent findings support previous observations suggesting that atopic dermatitis and rhinitis often accompany or precede the development of asthma. Further data support the notion that early-life exposure to domestic animals, a farming environment, passive smoking, and being raised in a large family, may be protective against the development of atopy and/or allergic diseases, although this seems modulated by genetic factors. Furthermore, the appearance of house-dust-mite-specific immunoglobulin E antibodies in early childhood has been identified as a major risk factor for the development of asthma in children with atopic dermatitis; and the association between sensitization to specific allergens and airway hyperresponsiveness was reported to be the strongest for indoor allergens such as house-dust-mite and cat. Allergen exposure can increase airway responsiveness in non-asthmatic subjects with allergic rhinitis and is associated with an increase in markers of lower airway inflammation, particularly with indoor allergens. Furthermore, nasal allergen provocation can induce bronchial inflammation and vice versa, suggesting close interrelations between upper and lower airways. In summary, the recent observations on the relationships between atopy, rhinitis and asthma support the hypothesis of a unique systemic condition with variable manifestations, which may develop following an imbalance between T helper cell types 1 and 2 lymphocyte populations. The latter may be influenced by environmental exposure in early life. Upper- and lower-airway inflammatory events influence each other, supporting the concept of 'united airways'. Further studies should look at the relationships between these conditions to identify individuals at high-risk of developing them and develop strategies to possibly prevent their onset.

Although Bacillus cereus sensu lato are important both from an ecological and an economical point of view, little is known about their population structure, ecology, and relationships with other organisms. In the present work, the genotypic similarity of arthropod-borne B. cereus s.l. isolates, and their symbiotic relationship with the host are assessed. Bacilli of this group were recovered from the digestive tracts of sow bugs (Porcellio scaber) collected in three closely located sites. Their genotypic diversity was investigated using pulse-field gel electrophoresis (PFGE) following the whole-genome DNA digestions with NotI and AscI, and PCR amplification of virulence genes. The majority of the sow-bug Bacillus cereus sensu stricto isolates originating from the same but also from different sites displayed identical PFGE patterns, virulence gene content and enterotoxicity, indicating strong genetic and genomic relationships. The sow-bug Bacillus mycoides/Bacillus pseudomycoides strains displayed a higher diversity. The isopod-B. cereus s.l. relationship was also evaluated using antibiotic-resistant derivatives of B. cereus s.s., B. mycoides/B. pseudomycoides and Bacillus thuringiensis reintroduced into sow bugs. Both spores and vegetative cells of B. cereus s.l. were recovered from sow bugs over a 30-day period, strongly suggesting that these bacteria are natural residents of terrestrial isopods.

The social network data has the user as node and edge as relation forming a friend relation graph. This research is conducting different meaning of every nodes relation in the social network. Ontology was perfect match science to describe the social network data as conceptual and domain. Ontology gives essential relationship in a social network more than a current graph. Ontology proposed as a standard for knowledge representation for the semantic web by World Wide Web Consortium. The formal data representation use Resource Description Framework (RDF) and Web Ontology Language (OWL) which is strategic for Open Knowledge-Based website data. Ontology used in the semantic description for a relationship in the social network, it is open to developing semantic based relationship ontology by adding and modifying various and different relationship to have influential people as a conclusion. This research proposes a model using OWL and RDF for influential people identification in the social network. The study use degree centrality, between ness centrality, and closeness centrality measurement for data validation. As a conclusion, influential people identification in Facebook can use proposed Ontology model in the Group, Photos, Photo Tag, Friends, Events and Works data.

Risk-Return Relationship in a Complex Adaptive System

2012-01-01

For survival and development, autonomous agents in complex adaptive systems involving the human society must compete against or collaborate with others for sharing limited resources or wealth, by using different methods. One method is to invest, in order to obtain payoffs with risk. It is a common belief that investments with a positive risk-return relationship (namely, high risk high return and vice versa) are dominant over those with a negative risk-return relationship (i.e., high risk low return and vice versa) in the human society; the belief has a notable impact on daily investing activities of investors. Here we investigate the risk-return relationship in a model complex adaptive system, in order to study the effect of both market efficiency and closeness that exist in the human society and play an important role in helping to establish traditional finance/economics theories. We conduct a series of computer-aided human experiments, and also perform agent-based simulations and theoretical analysis to confirm the experimental observations and reveal the underlying mechanism. We report that investments with a negative risk-return relationship have dominance over those with a positive risk-return relationship instead in such a complex adaptive systems. We formulate the dynamical process for the system's evolution, which helps to discover the different role of identical and heterogeneous preferences. This work might be valuable not only to complexity science, but also to finance and economics, to management and social science, and to physics. PMID:22479416

• Background and Aims Hylocereus and Selenicereus are native to tropical and sub-tropical America. Based on its taxonomic status and crossability relations it was postulated that H. megalanthus (syn. S. megalanthus) is an allotetraploid (2n = 4x = 44) derived from natural hybridization between two closely related diploid taxa. The present work aimed at elucidating the genetic relationships between species of the two genera. • Methods Crosses were performed and the putative hybrids were analysed by chromosome counts and morphological traits. The ploidy level of hybrids was confirmed by fluorescent in situ hybridization (FISH) of rDNA sites. Genomic in situ hybridization (GISH) was used in an attempt to identify the putative diploid genome donors of H. megalanthus and an artificial interploid hybrid. • Key Results Reciprocal crosses among four diploid Hylocereus species (H. costaricensis, H. monacanthus (syn. H. polyrhizus), H. undatus and Hylocereus sp.) yielded viable diploid hybrids, with regular chromosome pairing. Reciprocal crosses between these Hylocereus spp. and H. megalanthus yielded viable triploid, pentaploid, hexaploid and aneuploid hybrids. Morphological and phenological traits confirm the hybrid origin. In situ detection of rDNA sites was in accord with the ploidy status of the species and hybrid studied. GISH results indicated that overall sequence composition of H. megalanthus is similar to that of H. ocamponis and S. grandiflorus. High sequence similarity was also found between the parental genomes of H. monacanthus and H. megalanthus in one triploid hybrid. • Conclusions The ease of obtaining partially fertile F1 hybrids and the relative sequence similarity (in GISH study) suggest close genetic relationships among the taxa analysed.

Background: Neuronal intermediates that communicate estrogen and progesterone feedback to gonadotropin-releasing hormone (GnRH) neurons are essential for modulating reproductive cyclicity. Individually, kisspeptin and nitric oxide (NO) influence GnRH secretion. However, it is possible these two neuronal intermediates interact with one another to affect reproductive cyclicity. We investigated the neuroanatomical relationship of one isoform of the enzyme that synthesizes NO, neuronal nitric oxide synthase (nNOS), to kisspeptin and GnRH in adult female rhesus monkeys and sheep using dual-label immunofluorescence. Additionally, we evaluated if the phase of the reproductive cycle would affect these relationships. Overall, no effect of stage of cycle was observed for any variable in this study. In the arcuate nucleus (ARC) of sheep, 98.8±3.5% of kisspeptin neurons colocalized with nNOS, and kisspeptin close-contacts were observed onto nNOS neurons. In contrast to ewes, no colocalization was observed between kisspeptin and nNOS in the infundibular arcuate nucleus (INF ARC) of primates, but kisspeptin fibers were apposed to nNOS neurons. In the preoptic area (POA) of ewes, 15.0±4.2% of GnRH neurons colocalized with nNOS. In primates, 38.8±10.1% of GnRH neurons in the mediobasal hypothalamus (MBH) colocalized with nNOS, and GnRH close-contacts were observed onto nNOS neurons in both sheep and primates. Although species differences were observed, this work establishes a neuroanatomical framework between nNOS and kisspeptin and nNOS and GnRH in adult female nonhuman primates and sheep.

Further studies to extend and test the area-time-integral technique applied to satellite data

NASA Technical Reports Server (NTRS)

Smith, Paul L.; Vonderhaar, Thomas H.

1993-01-01

The principal goal of this project is to establish relationships that would allow application of area-time integral (ATI) calculations based upon satellite data to estimate rainfall volumes. The research has been pursued using two different approaches, which for convenience can be designated as the 'fixed-threshold approach' and the 'variable-threshold approach'. In the former approach, an attempt is made to determine a single temperature threshold in the satellite infrared data that would yield ATI values for identifiable cloud clusters which are most closely related to the corresponding rainfall amounts. Results thus far have indicated that a strong correlation exists between the rain volumes and the satellite ATI values, but the optimum threshold for this relationship seems to differ from one geographic location to another. The difference is probably related to differences in the basic precipitation mechanisms that dominate in the different regions. The average rainfall rate associated with each cloudy pixel is also found to vary across the spectrum of ATI values. Work on the second, or 'variable-threshold', approach for determining the satellite ATI values was essentially suspended during this period due to exhaustion of project funds. Most of the ATI work thus far has dealt with cloud clusters from the Lagrangian or 'floating-target' point of view. For many purposes, however, the Eulerian or 'fixed-target' perspective is more appropriate. For a very large target area encompassing entire cluster life histories, the rain volume-ATI relationship would obviously be the same in either case. The important question for the Eulerian perspective is how small the fixed area can be made while maintaining consistency in that relationship.

Structure-function relationships in tendons: a review

PubMed Central

2008-01-01

The purpose of the current review is to highlight the structure-function relationship of tendons and related structures to provide an overview for readers whose interest in tendons needs to be underpinned by anatomy. Because of the availability of several recent reviews on tendon development and entheses, the focus of the current work is primarily directed towards what can best be described as the ‘tendon proper’ or the ‘mid-substance’ of tendons. The review covers all levels of tendon structure from the molecular to the gross and deals both with the extracellular matrix and with tendon cells. The latter are often called ‘tenocytes’ and are increasingly recognized as a defined cell population that is functionally and phenotypically distinct from other fibroblast-like cells. This is illustrated by their response to different types of mechanical stress. However, it is not only tendon cells, but tendons as a whole that exhibit distinct structure-function relationships geared to the changing mechanical stresses to which they are subject. This aspect of tendon biology is considered in some detail. Attention is briefly directed to the blood and nerve supply of tendons, for this is an important issue that relates to the intrinsic healing capacity of tendons. Structures closely related to tendons (joint capsules, tendon sheaths, pulleys, retinacula, fat pads and bursae) are also covered and the concept of a ‘supertendon’ is introduced to describe a collection of tendons in which the function of the whole complex exceeds that of its individual members. Finally, attention is drawn to the important relationship between tendons and fascia, highlighted by Wood Jones in his concept of an ‘ectoskeleton’ over half a century ago – work that is often forgotten today.

The Ogasawara Islands are oceanic islands and harbor a unique endemic flora. There are three fig species (Ficus boninsimae, F. nishimurae and F. iidaiana) endemic to the Ogasawara Islands, and these species have been considered to be closely related to Ficus erecta, and to have diverged within the islands. However, this hypothesis remains uncertain. To investigate this issue, we assessed the phylogenetic relationships of the Ogasawara figs and their close relatives occurring in Japan, Taiwan and South China based on six plastid genome regions, nuclear ITS region and two nuclear genes. The plastid genome-based tree indicated a close relationship between the Ogasawara figs and F. erecta, whereas some of the nuclear gene-based trees suggested this relationship was not so close. In addition, the phylogenetic analyses of the pollinating wasps associated with these fig species based on the nuclear 28S rRNA and mitochondrial cytB genes suggested that the fig-pollinating wasps of F. erecta are not sister to those of the Ogasawara figs These results suggest the occurrence of an early hybridization event(s) in the lineage leading to the Ogasawara figs.

the transition to parenthood (TTP) is associated with changes to a couple's relationship. Quantitative evidence shows the TTP is associated with reduced satisfaction and quality of a couples' relationships. Qualitative research provides information on the lived experience of couples in the TTP so can provide a more in-depth understanding of the impact. This review therefore aimed to synthesise qualitative research of the perceived impact of the TTP on a couple's relationship in contemporary Western society. a systematic search was conducted of nine databases and grey literature. Key author, citation and reference searches were also undertaken. Papers were included if they presented qualitative data of romantic partner relationships during the TTP with parents aged 18 or over. Studies were restricted to those conducted from 1996 in Western societies. Analysis was conducted using meta-ethnography. searches identified 5256 papers. After applying inclusion criteria 12 papers were included in the meta-synthesis. Six main themes were identified: (1) Adjustment Phase (a period of change in the relationship), (2) Focus on the Baby (with a sub-theme of feeling unprepared for the relationship impact), (3) Communication (shifts in communication patterns and importance), (4) Intimacy (changes to sexual relations, romance and closeness), (5) Strain on the Relationship (short-term or prolonged), and (6) Strengthened Relationships (deepening of connection and new affinity). Except for the themes of Strain on the Relationship and Strengthened Relationships, the findings showed the TTP had positive and negative impacts on couples' relationships. the review highlights a range of TTP relationship issues that couples experience and may require help with. Health care professionals working with parents in the TTP may be able to provide support through antenatal education that includes preparation for relationship changes, and provision of postnatal support to identify and overcome problems.

Concern is growing regarding frequent and excessive misuse of alcohol by young people. The average age at which young people in Europe start to drink is twelve and a half, and during the last decade, the quantity of alcohol consumed by younger adolescents in the UK has increased. Families are known to play an important role in shaping young people's alcohol misuse, although family risk and protective factors associated with misuse in a UK context are in need of further investigation. The study used a cross-sectional design, involving secondary analyses of self-completion questionnaire responses from 6,628 secondary school children (i.e. aged 11-16 years), from 12 schools within an urban location in Wales. Items relating to family functioning and perceived parental attitudes were first subjected to factor analysis. Associations of family closeness and conflict, parental monitoring and attitudes and family history of substance misuse with children's self reported alcohol consumption were examined using logistic regression analyses. Approximately three quarters of respondents reported having tried alcohol, most of whom had first tried alcohol aged 12 or under. Parental monitoring and family closeness were positively correlated with one another and were both associated with significantly lower levels of drinking behaviours. Family violence and conflict, more liberal parental attitudes towards substance use and towards alcohol and petty crime, and family history of substance misuse were positively correlated with one another and with higher levels of drinking behaviours. Parental monitoring was identified as the family functioning factor most consistently associated with drinking behaviour in multivariate analyses. Significant relationships were found between young people's drinking behaviours and perceptions of risk and protective factors in the family environment. Parental monitoring was strongly associated with family closeness and appeared to form one part of a parenting style of more general communication and regulation of children's behaviour. Findings support the need for alcohol misuse prevention interventions which address risk and protective factors within the family setting. Timing of such prevention work should be related both to the development of family relationships and the age at which young people begin drinking alcohol.

A phylotranscriptomic backbone of the orb-weaving spider family Araneidae (Arachnida, Araneae) supported by multiple methodological approaches.

2018-04-07

The orb-weaving spider family Araneidae is extremely diverse (>3100 spp.) and its members can be charismatic terrestrial arthropods, many of them recognizable by their iconic orbicular snare web, such as the common garden spiders. Despite considerable effort to better understand their backbone relationships based on multiple sources of data (morphological, behavioral and molecular), pervasive low support remains in recent studies. In addition, no overarching phylogeny of araneids is available to date, hampering further comparative work. In this study, we analyze the transcriptomes of 33 taxa, including 19 araneids - 12 of them new to this study - representing most of the core family lineages, to examine the relationships within the family using genomic-scale datasets resulting from various methodological treatments, namely ortholog selection and gene occupancy as a measure of matrix completion. Six matrices were constructed to assess these effects by varying orthology inference method and gene occupancy threshold. Orthology methods used are the benchmarking tool BUSCO and the tree-based method UPhO; three gene occupancy thresholds (45%, 65%, 85%) were used to assess the effect of missing data. Gene tree and species tree-based methods (including multi-species coalescent and concatenation approaches, as well as maximum likelihood and Bayesian inference) were used totalling 17 analytical treatments. The monophyly of Araneidae and the placement of core araneid lineages were supported, together with some previously unsound backbone divergences; these include high support for Zygiellinae as the earliest diverging subfamily (followed by Nephilinae), the placement of Gasteracanthinae as sister group to Cyclosa and close relatives, and close relationships between the Araneus + Neoscona clade and Cyrtophorinae + Argiopinae clade. Incongruences were relegated to short branches in the clade comprising Cyclosa and its close relatives. We found congruence between most of the completed analyses, with minimal topological effects from occupancy/missing data and orthology assessment. The resulting number of genes by certain combinations of orthology and occupancy thresholds being analyzed had the greatest effect on the resulting trees, with anomalous outcomes recovered from analysis of lower numbers of genes.

In this study, the interaction between individual differences in working memory capacity, which were assessed by the Korean version of the California Verbal Learning Test (K-CVLT), and the effects of oculomotor task load on word recall performance are examined in a dual-task experiment. We hypothesized that varying levels of oculomotor task load should result in different demands on cognitive resources. The verbal working memory task used in this study involved a brief exposure to seven words to be remembered, followed by a 30-second delay during which the subject carried out an oculomotor task. Then, memory performance was assessed by having the subjects recall as many words as possible. Forty healthy normal subjects with no vision-related problems carried out four separate dual-tasks over four consecutive days of participation, wherein word recall performances were tested under unpredictable random SPEM (smooth pursuit eye movement), predictive SPEM, fixation, and eyes-closed conditions. The word recall performance of subjects with low K-CVLT scores was significantly enhanced under predictive SPEM conditions as opposed to the fixation and eyes-closed conditions, but performance was reduced under the random SPEM condition, thus reflecting an inverted-U relationship between the oculomotor task load and word recall performance. Subjects with high K-CVLT scores evidenced steady word recall performances, regardless of the type of oculomotor task performed. The concurrent oculomotor performance measured by velocity error did not differ significantly among the K-CVLT groups. However, the high-scoring subjects evidenced smaller phase errors under predictive SPEM conditions than did the low-scoring subjects; this suggests that different resource allocation strategies may be adopted, depending on individuals' working memory capacity.

This project involves discovering how the permeability effect inside a close compartment in processing. After the appropriate pressure range was found, the close compartment was designed by studying the relationship between pressure output and the flow rate. A variety of pressure ranges have been used in this test to determine the effective pressure range that can be applied to the manufacturing process. Based on the results, the suitable pressure ranges were found between 55 psi to 75 psi. These pressures have been chosen based on the area covered on the product surfaces and time taken to penetrate the proposed area. The relationship between pressure and flow rate have been found to be directly proportional until 75 psi only. In conclusion, 70 psi for the proposed design of close compartment mould is suitable to be used to fulfill the required area of 120 mm square within 90 seconds.

Cognitive functioning is more closely related to real-life mobility than to laboratory-based mobility parameters.

Increasing evidence indicates that mobility depends on cognitive resources, but the exact relationships between various cognitive functions and different mobility parameters still need to be investigated. This study examines the hypothesis that cognitive functioning is more closely related to real-life mobility performance than to mobility capacity as measured with standardized laboratory tests. The final sample used for analysis consisted of 66 older adults (72.3 ± 5.6 years). Cognition was assessed by measures of planning (HOTAP test), spatial working memory (Grid-Span test) and visuospatial attention (Attention Window test). Mobility capacity was assessed by an instrumented version of the Timed Up-and-Go test (iTUG). Mobility performance was assessed with smartphones which collected accelerometer and GPS data over one week to determine the spatial extent and temporal duration of real-life activities. Data analyses involved an exploratory factor analysis and correlation analyses. Mobility measures were reduced to four orthogonal factors: the factor 'real-life mobility' correlated significantly with most cognitive measures (between r   =  .229 and r   =  .396); factors representing 'sit-to-stand transition' and 'turn' correlated with fewer cognitive measures (between r   =  .271 and r   =  .315 and between r   =  .210 and r   =  .316, respectively), and the factor representing straight gait correlated with only one cognitive measure ( r   =  .237). Among the cognitive functions tested, visuospatial attention was associated with most mobility measures, executive functions with fewer and spatial working memory with only one mobility measure. Capacity and real-life performance represent different aspects of mobility. Real-life mobility is more closely associated with cognition than mobility capacity, and in our data this association is most pronounced for visuospatial attention. The close link between real-life mobility and visuospatial attention should be considered by interventions targeting mobility in old age.

The doctor's dilemma.

Irvine, D H; Donaldson, L J

1995-10-01

The close relationship between expenditure on health care and the countless individual judgements made by doctors for their patients means that any discussion about rationing must involve the process of clinical decision-making. Increasingly, doctors are being drawn into rationing by two powerful forces. Firstly, through the corporate responsibilities of those working within a managed health care system in which organisational objectives and budgetary constraints are agreed and specified in a much more explicit way than ever before. Secondly, by the professionally-led movement towards more clinically effective practice. These, in combination, are leading towards a fundamental review of the nature and ethical basis of clinical practice in which the duty of doctors to individual patients must be balanced against the wider considerations.

The aim of this study was to identify the outcomes of parental bereavement and the changes in life experience that follow the traumatic death of a teenage child. The results of the study are aimed to assist counselors and educators who work with themes of grief and loss. From 17 in-depth interviews from parents bereaved by the Sewol ferry disaster of 2014 in South Korea, three main categories were found to capture the reality for parents after the sudden and traumatic death of a teenage child: (a) personal changes, (b) changes in close relationships, and (c) changes in social life. Recommendations for future research and potential implications were discussed.

Encountering Ehrenberg: tracing the development of psychoanalytic therapy at the intimate edge.

PubMed

Laidlaw, Christine; Heusser, Shelley

2014-01-01

This article illustrates the thinking-through processes and clinical applications of D.B. Ehrenberg's ideas within the therapeutic situation. During the last four decades, Ehrenberg has articulated that the psychoanalytic relationship is at its most compelling when it evolves at "the intimate edge" of the therapist's self and that of the patient. She invites us to explore and process the relational dynamics of the therapeutic dyad within the consulting room. In tribute to Ehrenberg's work, we reflect on two individuals closed up in their self-reliance, who start to break open to their desires for intimacy when their therapist opens up his own self within the uniquely meaningful space co-created in the analytic therapy.

Relationships of trust between research participants and researchers are often considered paramount to successful research; however, we know little about participants' perspectives. We examined whom research participants trusted when taking part in research. Using a qualitative approach, we interviewed 36 research participants, including eight Indigenous participants. Thematic analysis was used to analyze the data. This article focuses on findings related to non-Indigenous participants. In contrast to Indigenous participants, non-Indigenous participants placed their trust in research institutions because of their systems of research ethics, their reputation and prestige. Researchers working in non-Indigenous contexts need to be cognizant that the trust that participants place in them is closely connected with the trust that participants have in the institution.

The Automated Work Administration System (AWAS) is an automated scheduling system developed at GTE. A typical work center has 1000 employees and processes 4000 jobs each day. Jobs are geographically distributed within the service area of the work center, require different skills, and have to be done within specified time windows. Each job can take anywhere from 12 minutes to several hours to complete. Each employee can have his/her individual schedule, skill, or working area. The jobs can enter and leave the system at any time The employees dial up to the system to request for their next job atmore » the beginning of a day or after a job is done. The system is able to respond to the changes dynamically and produce close to optimum solutions at real time. We formulate the real world problem as a minimum cost network flow problem. Both employees and jobs are formulated as nodes. Relationship between jobs and employees are formulated as arcs, and working hours contributed by employees and consumed by jobs are formulated as flow. The goal is to minimize missed commitments. We solve the problem with the successive shortest path algorithm. Combined with pre-processing and post-processing, the system produces reasonable outputs and the response time is very good.« less

The emotional climate of care-giving in home-care services.

PubMed

Olsson, E; Ingvad, B

2001-11-01

The emotional aspects of the care-giving relationship in home-care services are studied, starting from the home-care recipients' and the home-care workers' perception of the emotional climate. Their experiences of the care-giving relationship and the influence from different aspects of the care-giving situation and social processes in the work organisation are explored. Two hundred and twenty-two recipients and their home-care workers in three typical Swedish municipalities were studied. The emotional climate is described with the help of a scale of 85 adjectives. Results show that home-care workers are more likely to experience the climate with a higher degree of emotionality. There is symmetry between the parties in the perception of a negative climate. However, if one party perceives the climate as close the other party is more likely to perceive it as rational or instrumental. The organisational processes, especially the group climate of the work team, principally influence the home-care recipients' perceptions. The workers' perceptions are principally influenced by age and gender of the recipients and the workers' own age. The emotional climate is constructed in a process between the parties, depending on their responses to each other. Tendencies to perceive a specific climate are strengthened or weakened by context variables and this in turn changes the care-giving interaction.
