Many insects hover with their wings beating in a horizontal plane (‘normal hovering’), while some insects, e.g., hoverflies and dragonflies, hover with inclined stroke-planes. Here, we investigate the lateral dynamic flight stability of a hovering model hoverfly. The aerodynamic derivatives are computed using the method of computational fluid dynamics, and the equations of motion are solved by the techniques of eigenvalue and eigenvector analysis. The following is shown: The flight of the insect is unstable at normal hovering (stroke-plane angle equals 0) and the instability becomes weaker as the stroke-plane angle increases; the flight becomes stable at a relatively large stroke-plane angle (larger than about 24°). As previously shown, the instability at normal hovering is due to a positive roll-moment/side-velocity derivative produced by the ‘changing-LEV-axial-velocity’ effect. When the stroke-plane angle increases, the wings bend toward the back of the body, and the ‘changing-LEV-axial-velocity’ effect decreases; in addition, another effect, called the ‘changing-relative-velocity’ effect (the ‘lateral wind’, which is due to the side motion of the insect, changes the relative velocity of its wings), becomes increasingly stronger. This causes the roll-moment/side-velocity derivative to first decrease and then become negative, resulting in the above change in stability as a function of the stroke-plane angle. (paper)

The current study sought to conduct a preliminary investigation of the effectiveness and feasibility of a novel, self-guided online self-compassion training for reducing psychological distress and increasing self-compassion and happiness among psychology trainees. A 6-week online self-compassion cultivation program was developed and delivered to Australian psychology trainees (n = 37), and a pre-experimental repeated-measures design was used to collect change data on self-compassion, happiness, perceived stress, emotion regulation difficulties as well as symptoms of depression, anxiety, and stress. Participants reported significant increases in self-compassion and happiness and significant decreases in depression, stress, and emotion regulation difficulties between pretest and posttest, with the majority of changes maintained at 3-month follow up.  This study provides preliminary evidence supporting the effectiveness and acceptability of online self-compassion training as a positive, integrated, and meaningful way of reducing distress and promoting self-compassion and happiness among trainee psychologists. © 2016 Wiley Periodicals, Inc.

Today the proportion of acute patients entering the health care system through emergency departments continues to grow, the number of uninsured patients relying primarily on treatment in the emergency department is increasing, and patients' average acuities are rising. At the same time, support resources are constrained, while reimbursement and reputation depends increasingly on publicly available measures of patient satisfaction. It is important to understand the potential effect of these pressures on direct care staff. This study explores the prevalence of compassion satisfaction, burnout, and compassion fatigue among emergency nurses and nurses in other selected inpatient specialties. Emergency nurses and nurses from 3 other specialty units self-selected participation in a cross-sectional survey. Participants completed a sociodemographic profile and the Professional Quality of Life: Compassion Satisfaction and Fatigue Subscales, R-IV. Scale scores were summed for compassion satisfaction, burnout, and compassion fatigue for emergency nurses and compared with those of nurses in other specialties. Approximately 82% of emergency nurses had moderate to high levels of burnout, and nearly 86% had moderate to high levels of compassion fatigue. Differences between emergency nurses and those working in 3 other specialty areas, that is, oncology, nephrology, and intensive care, on the subscales for compassion satisfaction, burnout, or compassion fatigue did not reach the level of statistical significance. However, the scores of emergency nurses evidenced a risk for less compassion satisfaction, while intensive care nurses demonstrated a higher risk for burnout and oncology nurses reflected a risk for higher compassion fatigue. ED nurse managers, along with other nurse leaders, are faced with the competing demands of managing the satisfaction of patients, recruitment and retention of experienced nurses, and provision of quality and safe care customized to patients' needs

Ed Pellegrino understands the virtues within the dynamics of an action that does not follow the principles but comes from a way of reasonable knowledge that recognizes the very purpose of good to steer correctly makes a good agent. One of the characteristic action of the physician is the compassion that is a trait of his character, unifying psychological, cultural, sociological, ethnic and intellectuals who channels the cognitive aspect of healing and in particular the reality of a particular patient. Most own medical compassion is what Pellegrino calls its intellectual dimension, which is a form of integrated understanding that enables the achievement of all levels at which the patient is well defined. It is the usual choice, grasp, handle and weigh the uniqueness with which the patient lives the disease. The need for compassion, and the rest of the medical profession's own virtues, returns us once again to the need for the formation of a subject capable and unity between all virtues.

Compassion fatigue is a state of detachment and isolation experienced when healthcare providers repeatedly engage with patients in distress. Compassion fatigue can hinder empathy and cause extreme tension. Prior research suggests 73.8 % of genetic counselors are at moderate to high risk for compassion fatigue and approximately 1 in 4 have considered leaving the field as a result Injeyan et al. (Journal of Genetic Counseling, 20, 526-540, 2011). Empirical data to establish a reliable profile of genetic counselors at risk for compassion fatigue are limited. Thus the purpose of this study was to establish a profile by assessing relationships between state and trait anxiety, burnout, compassion satisfaction, selected demographics and compassion fatigue risk in practicing genetic counselors. Practicing genetic counselors (n = 402) completed an anonymous, online survey containing demographic questions, the State-Trait Anxiety Inventory, and the Professional Quality of Life scale. Multiple regression analysis yielded four significant predictors which increase compassion fatigue risk (accounting for 48 % of the variance): higher levels of trait anxiety, burnout, and compassion satisfaction, and ethnicity other than Caucasian. Additional findings, study limitations, practice implications, and research recommendations are provided.

Compassion fatigue in nursing has been shown to impact the quality of patient care and employee satisfaction and engagement. The aims of this study were to determine the prevalence and severity of compassion fatigue among pediatric nurses and variations in prevalence based on respondent demographics using a cross-sectional survey design. Nurses under 40 years of age, with 6-10 years of experience and/or working in a medical-surgical unit had significantly lower compassion satisfaction and higher levels of burnout. Secondary traumatic stress from caring for children with severe illness or injury or end of life was a key contributor to compassion fatigue. Copyright © 2015 Elsevier Inc. All rights reserved.

Empowerment is often a desired outcome for health programs; however, it is rarely evaluated. One way to increase empowerment may be through self-compassion. The authors of the current study aimed to determine whether self-compassion and empowerment were positively related. Two hundred and five women (ages 18 to 48 years) were recruited from a pool of undergraduate students at a university in the southeastern United States in the summer/fall of 2012. Participants completed the study using Qualtrics, an online survey system. Participants wrote about a fight in a romantic relationship and were randomly assigned to write about the fight either self-compassionately or generally. Empowerment and perceptions of the fight were assessed as dependent measures. Hierarchical regression analyses investigated the relation of self-compassion, manipulated self-compassion, and their interaction with empowerment. A significant positive relationship was found between self-compassion and empowerment. However, manipulated self-compassion was not significantly related to empowerment. These findings suggested that self-compassion and empowerment were strongly related, but using a short-term self-compassion intervention may not be strong enough to influence empowerment. Empowerment-based practitioners may find empowerment increases more easily in women who are self-compassionate. If self-compassion is incorporated into empowerment settings, a long-term intervention may be necessary.

Limiting oxygen concentration for extinction of upward spreading flames over inclined thin polyethylene-insulated NiCr electrical wires with opposed-flow under normal- and micro-gravity

Materials, such as electrical wire, used in spacecraft must pass stringent fire safety standards. Tests for such standards are typically performed under normal gravity conditions and then extended to applications under microgravity conditions. The experiments reported here used polyethylene (PE)-insulated (thickness of 0.15 mm) Nichrome (NiCr)-core (diameter of 0.5 mm) electrical wires. Limiting oxygen concentrations (LOC) at extinction were measured for upward spreading flame at various forced opposed-flow (downward) speeds (0−25 cm/s) at several inclination angles (0−75°) under normal gravity conditions. The differences from those previously obtained under microgravity conditions were quantified and correlated to provide a reference for the development of fire safety test standards for electrical wires to be used in space exploration. It was found that as the opposed-flow speed increased for a specified inclination angle (except the horizontal case), LOC first increased, then decreased and finally increased again. The first local maximum of this LOC variation corresponded to a critical forced flow speed resulted from the change in flame spread pattern from concurrent to counter-current type. This critical forced flow speed correlated well with the buoyancy-induced flow speed component in the wire\\'s direction when the flame base width along the wire was used as a characteristic length scale. LOC was generally higher under the normal gravity than under the microgravity and the difference between the two decreased as the opposed-flow speed increases, following a reasonably linear trend at relatively higher flow speeds (over 10 cm/s). The decrease in the difference in LOC under normal- and microgravity conditions as the opposed-flow speed increases correlated well with the gravity acceleration component in the wire\\'s direction, providing a measure to extend LOC determined by the tests under normal gravity conditions (at various inclination angles and opposed

This study experimentally examined the impact of exposure to fitspiration images and self-compassion quotes on social media on young women's body satisfaction, body appreciation, self-compassion, and negative mood. Female undergraduate students (N=160) were randomly assigned to view either Instagram images of fitspiration, self-compassion quotes, a combination of both, or appearance-neutral images. Results showed no differences between viewing fitspiration images compared to viewing neutral images, except for poorer self-compassion among those who viewed fitspiration images. However, women who viewed self-compassion quotes showed greater body satisfaction, body appreciation, self-compassion, and reduced negative mood compared to women who viewed neutral images. Further, viewing a combination of fitspiration images and self-compassion quotes led to positive outcomes compared to viewing only fitspiration images. Trait levels of thin-ideal internalisation moderated some effects. The findings suggest that self-compassion might offer a novel avenue for attenuating the negative impact of social media on women's body satisfaction. Copyright © 2017 Elsevier Ltd.

This is the first two-phase Australian study to explore the factors impacting upon compassion satisfaction, compassion fatigue, anxiety, depression and stress and to describe the strategies nurses use to build compassion satisfaction into their working lives. Compassion fatigue has been found to impact on job satisfaction, the quality of patient care and retention within nursing. This study provides new knowledge on the influences of anxiety, stress and depression and how they relate to compassion satisfaction and compassion fatigue. In Phase 2 of the study, 10 nurses from Phase 1 of the study participated in individual interviews and a focus group. A semi-structured interview schedule guided the conversations with the participants. Data analysis resulted in seven main themes: social networks and support;infrastructure and support; environment and lifestyle; learning; leadership; stress; and suggestions to build psychological wellness in nurses. Findings suggest that a nurse’s capacity to cope is enhanced through strong social and collegial support, infrastructure that supports the provision of quality nursing care and positive affirmation. These concepts are strongly linked to personal resilience. for nursing management These findings support the need for management to develop appropriate interventions to build resilience in nurses.

Objectives Cultivation of compassion is a useful way to treat mental problems, but some individuals show resistance. Fears of compassion can be an obstacle for clinicians when providing psychotherapy, and for clients when engaging in interpersonal relationships. Despite its importance, a Japanese version of fears of compassion scales (for others, from others, and for self) has not yet been developed. This study developed a Japanese version of the Fears of Compassion Scales and tested its reliability and validity. Design This study used a cross-sectional design, and a self-report procedure for collecting data. Methods A total of 485 students (121 males and 364 females) answered self-report questionnaires, including the draft Fears of Compassion Scales—Japanese version. Results There were distinctive factor structures for fear of compassion from others, and for self. The fear of compassion from others scale consisted of concern about compassion from others and avoidance of compassion from others. All scales had good internal consistency, test-retest reliability, face validity, and construct validity. Discrimination and difficulty were also calculated. Conclusions These results indicate that the Fears of Compassion Scales—Japanese version is a well-constructed and useful measure to assess fears of compassion and the existence of cultural differences in fears of compassion.

Studies have investigated burnout and compassion fatigue among nurses and effects in the nursing profession. However, there are limited investigations of burnout and compassion fatigue among undergraduate nursing students in South Africa, as nursing students may experience distressful situations during their nursing education course, which may have an impact during their training and in their profession as they graduate. The purpose of this descriptive study was to describe compassion satisfaction, compassion fatigue and burnout among undergraduate nursing students at a tertiary nursing institution. A quantitative descriptive study was conducted to describe compassion satisfaction, compassion fatigue and burnout among undergraduate nursing students at a tertiary nursing institution in KwaZulu-Natal. Convenience sampling was used. Sixty-seven undergraduate students (26 third-year and 41 fourth-year nursing students) took the self-test Professional Quality of Life Scale (ProQOL). The study results indicate that undergraduate students experienced average levels of compassion fatigue, burnout and compassion satisfaction. As shown in the study, some of the undergraduate students are experiencing compassion fatigue and burnout, associated with relieving suffering of others. Therefore, knowledge of compassion fatigue and burnout and the coping strategies should be part of nursing training.

The objective of this study was to extend the psychometric evaluation of a brief version of the Self Compassion Scale (SCS). A secondary analysis of data from an international sample of 1,967 English-speaking persons living with HIV disease was used to examine the factor structure, and reliability of the 12-item Brief Version Self Compassion Inventory (BVSCI). A Maximum Likelihood factor analysis and Oblimin with Kaiser Normalization confirmed a two-factor solution, accounting for 42.58% of the variance. The BVSCI supported acceptable internal consistencies, with .714 for the total scale and .822 for Factor I and .774 for Factor II. Factor I (lower self compassion) demonstrated strongly positive correlations with measures of anxiety and depression while Factor II (high self compassion) was inversely correlated with the measures. No significant differences were found in the BVSCI scores for gender, age, or having children. Levels of self-compassion were significantly higher in persons with HIV disease and other physical and psychological health conditions. The scale shows promise for the assessment of self-compassion in persons with HIV without taxing participants, and may prove essential in investigating future research aimed at examining correlates of self-compassion, as well as providing data for tailoring self-compassion interventions for persons with HIV.

Membrane fouling shorten the service life of the membrane and increases aeration rate for membrane surface cleaning. Two membrane bio-reactors, one for working and another for comparing, were set up to evaluate the feasibility of alleviating membrane fouling and improving wastewater treatment efficiency by integrating inclined-plate precipitation and membrane separation. The result show that: (1) Inclined-plate in reactor had a good effect on pollutant removal of membrane bioreactor. The main role of inclined-plate is dividing reactor space and accelerating precipitation. (2) Working reactor have better performance in COD, TN and TP removal, which can attribute to that working reactor (integrated inclined-plate-Membrane bioreactor) takes both advantages of membrane separation and biological treatment. When influent COD, TP and TN concentration is 163-248 mg/L, 2.08-2.81 mg/L and 24.38-30.49 mg/L in working reactor, effluent concentration is 27-35 mg/L, 0.53-0.59 mg/L and 11.28-11.56 mg/L, respectively. (3) Membrane fouling was well alleviated in integrated inclined-plate-Membrane bioreactor, and membrane normal service time is significantly longer than that in comparing reactor, which can attribute to accelerating precipitation of inclined-plate. In summary, integrated inclined-plate-Membrane bioreactor is a promising technology to alleviating membrane fouling and improving wastewater treatment efficiency, having good performance and bright future in application.

PanDA (Production and Distributed Analysis System) is a workload management system, widely used for data processing at experiments on Large Hadron Collider and others. COMPASS is a high-energy physics experiment at the Super Proton Synchrotron. Data processing for COMPASS runs locally at CERN, on lxbatch, the data itself stored in CASTOR. In 2014 an idea to start running COMPASS production through PanDA arose. Such transformation in experiment's data processing will allow COMPASS community to use not only CERN resources, but also Grid resources worldwide. During the spring and summer of 2015 installation, validation and migration work is being performed at JINR. Details and results of this process are presented in this paper.

Roney, Linda Nancy; Acri, Mary C

The purpose of this study was to describe levels of compassion satisfaction, compassion fatigue, and job satisfaction among pediatric nurses in the United States and determine if there was a relationship among these constructs. All members Society of Pediatric Nurses were sent an electronic invitation to participate, and those who consented received three measures; a demographic questionnaire, the Job Satisfaction Survey (JSS) and the Professional Quality of Life (ProQOL) measure. Three hundred eighteen (10.6%) of members of the Society of Pediatric Nurses participated in the study: Over three quarters (245, 76%) of the sample had another career before nursing. The sample's mean job satisfaction level was 149.8 (SD=29.74), which was significantly higher than published reported means for nurses. Bivariate analyses revealed a significant relationship between gender and the compassion satisfaction, in that women were more likely to evidence compassion satisfaction than men (t=1.967, p=.05, df=298). No other significant relationships were found. The majority of nurses had high levels of compassion satisfaction and job satisfaction; further, female gender was associated with higher levels of compassion satisfaction. This current study had a very high response from second-career nurses (n=245, 76.8%) and overall, the sample had higher levels of compassion satisfaction. It is possible that second career nurses are better equipped in some way that helps them mediate negative responses of caring as a pediatric nurse and future research should explore this. Due to the significant financial costs to institutions of having nurses who have low levels of job satisfaction and high levels on compassion fatigue, it is imperative for hospital administrators to develop infrastructures to support employees.

The effect of inclination on the low Prandtl number turbulent convection in a cylinder of unit aspect ratio was studied experimentally. The working fluid was sodium (Prandtl number Pr =0.0094 ), the measurements were performed for a fixed Rayleigh number Ra =(1.47 ±0.03 ) ×107 , and the inclination angle varied from β =0∘ (the Rayleigh-Bénard convection, the temperature gradient is vertical) up to β =90∘ (the applied temperature gradient is horizontal) with a step Δ β =10∘ . The effective axial heat flux characterized by the Nusselt number is minimal at β =0∘ and demonstrates a smooth growth with the increase of the cylinder inclination, reaching a maximum at angle β ≈70∘ and decreasing with a further increase of β . The maximal value of the normalized Nusselt number Nu (β )/Nu (0 ) was 1.21. In general, the dependence of Nu (β ) in a cylinder with unit aspect ratio is similar to what was observed in sodium convection in inclined long cylinders but is much weaker. The structure of the flow undergoes a significant transformation with inclination. Under moderate inclination (β ≲30∘ ), the fluctuations are strong and are provided by regular oscillations of large-scale circulation (LSC) and by turbulence. Under large inclination (β >60∘ ), the LSC is regular and the turbulence is weak, while in transient regimes (30∘border of transient and large inclinations. We find the first evidence of strong LSC fluctuations in low Prandtl number convective flow under moderate inclination. The rms azimuthal fluctuations of LSC, about 27∘ at β =0∘ , decrease almost linearly up to β =30∘ , where they are about 9∘. The angular fluctuations in the vicinity of the end faces are much stronger (about 37∘ at β =0∘ ) and weakly decrease up to β =20∘ . The strong anticorrelation of the fluctuations in two halves of the cylinder indicates the torsional character of LSC fluctuations. At β =30∘ , the intensity of the oscillations at the

Honeybees have at least three compass mechanisms: a magnetic compass; a celestial or sun compass, based on the daily rotation of the sun and sun-linked skylight patterns; and a backup celestial compass based on a memory of the sun's movements over time in relation to the landscape. The interactions of these compass systems have yet to be fully elucidated, but the celestial compass is primary in most contexts, the magnetic compass is a backup in certain contexts, and the bees' memory of the sun's course in relation to the landscape is a backup system for cloudy days. Here we ask whether bees have any further compass systems, for example a memory of the sun's movements over time in relation to the magnetic field. To test this, we challenged bees to locate the sun when their known celestial compass systems were unavailable, that is, under overcast skies in unfamiliar landscapes. We measured the bees' knowledge of the sun's location by observing their waggle dances, by which foragers indicate the directions toward food sources in relation to the sun's compass bearing. We found that bees have no celestial compass systems beyond those already known: under overcast skies in unfamiliar landscapes, bees attempt to use their landscape-based backup system to locate the sun, matching the landscapes or skylines at the test sites with those at their natal sites as best they can, even if the matches are poor and yield weak or inconsistent orientation.

Inclined monochromator for high heat-load synchrotron x-ray radiation

Khounsary, Ali M.

1994-01-01

A double crystal monochromator including two identical, parallel crystals, each of which is cut such that the normal to the diffraction planes of interest makes an angle less than 90 degrees with the surface normal. Diffraction is symmetric, regardless of whether the crystals are symmetrically or asymmetrically cut, enabling operation of the monochromator with a fixed plane of diffraction. As a result of the inclination of the crystal surface, an incident beam has a footprint area which is elongated both vertically and horizontally when compared to that of the conventional monochromator, reducing the heat flux of the incident beam and enabling more efficient surface cooling. Because after inclination of the crystal only a fraction of thermal distortion lies in the diffraction plane, slope errors and the resultant misorientation of the diffracted beam are reduced.

Benzo, Roberto P; Kirsch, Janae L; Nelson, Carlie

Decreased well-being of healthcare workers expressed as stress and decreased job satisfaction influences patient safety, patient satisfaction, and cost containment. Self-compassion has garnered recent attention due to its positive association with well-being and happiness. Discovering novel pathways to increase the well-being of healthcare workers is essential. This study sought to explore the influence of self-compassion on employee happiness in healthcare professionals. A total of 400 participants (mean age = 45 ± 14, 65% female) healthcare workers at a large teaching hospital were randomly asked to complete questionnaires assessing their levels of happiness and self-compassion, life conditions, and habits. Participants completed the Happiness Scale and Self-Compassion Scales, the Five Facet Mindfulness Questionnaire as well as variables associated with well-being: relationship status, the number of hours spent exercising a week, attendance at a wellness facility, and engagement in a regular spiritual practice. Self-compassion was significantly and independently associated with perceived happiness explaining 39% of its variance after adjusting for age, marital status, gender, time spent exercising, and attendance to an exercise facility. Two specific subdomains of self-compassion from the instrument used, coping with isolation and mindfulness, accounted for 95% of the self-compassion effect on happiness. Self-compassion is meaningfully and independently associated with happiness and well-being in healthcare professionals. Our results may have practical implications by providing specific self-compassion components to be targeted in future programs aimed at enhancing well-being in healthcare professionals.

The objective of this paper is to assess the core degradation modeling in COMPASS code by simulating the PHEBUS FPT3 experiment. For the comparison purpose, the numerical simulation by using MELCOR 2.1 have also conducted for the FPT3 experiment. Consequently, COMPASS results of PHEBUS FPT3 have been compared with the experimental data and MELCOR results. For the purpose of COMPASS code validation, the numerical simulation for PHEBUS FPT3 experiment has been conducted. The temperature of the main component has been secured by using COMPASS code for a fuel, cladding, control rod and surrounding structure. And they are compared with that of experimental data as well as MELCOR simulation results. MELCOR are showing that an oxidational reaction starts a little bit earlier time and has the slightly higher value of the accumulated hydrogen mass, while COMPASS code predicts the slightly lower value of the accumulated hydrogen mass.

Compassion is considered the cornerstone of nursing practice. However, the recent failures in delivering high-quality compassionate nursing care in the UK's National Health Service have brought the topic of compassion to the attention of the public, service providers, policy makers and academics. The aim of this study was to explore the nurses' views and experiences of a number of compassion-related issues in nursing and describe similarities and differences at an international level as well as from the different nursing roles of the participating nurses. An exploratory, cross-sectional descriptive study, using the International Online Compassion Questionnaire. A total of 1323 nurses from 15 countries completed the questionnaire. The majority of participants (59.5%) defined compassion as "Deep awareness of the suffering of others and wish to alleviate it" but definitions of compassion varied by country. Of participants, 69.6% thought compassion was very important in nursing and more than half (59.6%) of them argued that compassion could be taught. However, only 26.8% reported that the correct amount and level of teaching is provided. The majority of the participants (82.6%) stated that their patients prefer knowledgeable nurses with good interpersonal skills. Only 4.3% noted that they are receiving compassion from their managers. A significant relationship was found between nurses' experiences of compassion and their views about teaching of compassion. Our study is unique in identifying the views and experiences of nurses from 15 different countries worldwide. The findings reveal that compassion is neither addressed adequately in nursing education nor supported in the practice environment by managers. Self-report bias was inherent to our survey study design. Furthermore, the individual cultural differences and similarities in the findings are difficult to extrapolate owing to the fact that our analysis was at country level, as well as at the level of the

The present study examined the relative contributions of self-compassion, fear of self-compassion, and self-esteem in eating disorder pathology. One-hundred and fifty-five female undergraduate students and 97 females entering eating disorder treatment completed the Self-Compassion Scale, Fears of Compassion Scale, Rosenberg Self-Esteem Inventory, and Eating Disorder Examination Questionnaire. T-tests revealed that the patient group had lower mean self-compassion and higher mean fear of self-compassion than the student group. When controlling for self-esteem, high fear of self-compassion emerged as the strongest predictor of eating disorder pathology in the patient group, whereas low self-compassion was the strongest predictor in the student group. These preliminary results suggest that targeting fear of self-compassion may be important when intervening with individuals suffering from an eating disorder, whereas building self-compassion may be a valuable approach for eating disorder prevention.

Goetz, Jennifer L.; Keltner, Dacher; Simon-Thomas, Emiliana

2010-01-01

What is compassion? And how did it evolve? In this review, we integrate three evolutionary arguments that converge on the hypothesis that compassion evolved as a distinct affective experience whose primary function is to facilitate cooperation and protection of the weak and those who suffer. Our empirical review reveals compassion to have distinct appraisal processes attuned to undeserved suffering, distinct signaling behavior related to caregiving patterns of touch, posture, and vocalization...

Nurses often provide care for patients and families who are suffering and where emotions are heightened. Compassion is an essential component of the care that nurses provide. Emotions play an important role in the relationship and communication between nurses, patients and families. Self-compassion is the ability to be compassionate to oneself, without this ability nurses might not be prepared to be compassionate to patients. Emotionally intelligent persons perceive themselves as confident, better able to understand, control and manage their emotions. The purpose of this descriptive, correlational study was to examine the relationship between self-compassion and emotional intelligence. Participants were 135 nurses. The setting for this study was a health system with hospitals located in Queens, Nassau and Suffolk counties of New York, USA. Three of the hospitals in the study are located in Queens and/or the Queens/Nassau border. Queens is the most culturally diverse community in the USA. The patients served, as well as the nursing staff, are reflective of this cultural and religious diversity. Results indicated a positive correlation between self-compassion and emotional intelligence (r = 0.55). Recommendations for future research include: exploration of self-compassion and emotional intelligence in nurses, and identification of the benefits of enhancing self-compassion and emotional intelligence in nurses.

Evaporation of inclined water droplets

When a drop is placed on a flat substrate tilted at an inclined angle, it can be deformed by gravity and its initial contact angle divides into front and rear contact angles by inclination. Here we study on evaporation dynamics of a pure water droplet on a flat solid substrate by controlling substrate inclination and measuring mass and volume changes of an evaporating droplet with time. We find that complete evaporation time of an inclined droplet becomes longer as gravitational influence by inclination becomes stronger. The gravity itself does not change the evaporation dynamics directly, whereas the gravity-induced droplet deformation increases the difference between front and rear angles, which quickens the onset of depinning and consequently reduces the contact radius. This result makes the evaporation rate of an inclined droplet to be slow. This finding would be important to improve understanding on evaporation dynamics of inclined droplets. PMID:28205642

Full Text Available This is a systematic compilation study which aimed to determine whether psychiatry nurses were fatigue of compassion, or not. The screening of several databases revealed four articles fulfilling inclusion criteria of the study. While three of the articles examined were descriptive; one was in cross-sectional pattern. Along the inclusion criterions, no any Turkish article was determined regarding the subject. In these articles, compassion fatigue concept has usually been considered with “compassion satisfaction and burnout” concepts. According to the findings of aforesaid articles, it was determined that compassion satisfaction of psychiatry nurses was at low level; that their compassion fatigue and burnout levels were high; and as well that they showed post-traumatic stress symptoms.

Are Empathy and Compassion Bad for the Professional Social Worker?

Directory of Open Access Journals (Sweden)

Peter Nilsson

2014-11-01

Full Text Available Recent studies have shown that social workers and other professional helpers who work with traumatized individuals run a risk of developing compassion fatigue or secondary traumatic stress. Some researchers have hypothesized that helpers do this as a result of feeling too much empathy or too much compassion for their clients, thereby implying that empathy and compassion may be bad for the professional social worker. This paper investigates these hypotheses. Based on a review of current research about empathy and compassion it is argued that these states are not the causes of compassion fatigue. Hence, it is argued that empathy and compassion are not bad for the professional social worker in the sense that too much of one or the other will lead to compassion fatigue.

Full Text Available Self-compassion is defined by Neff as approaching to the self without judgment, criticism or punishment, sharing the stressful experiences with other people without isolation and holding the painful emotions and thoughts in mindful awareness without over identification. The studies showed that self-compassion has positive relationship with psychological well-being; has negative relationships with depression, anxiety, eating disorders, trauma and other psychological problems. Also, the findings from psychotherapy studies that try to strength self-compassion attracted a great deal of attention. The main aims of this article were reviewing the self-compassion concept toward the literature, summarizing the empirical findings in the context of self-compassion and discussing the usage of self-compassion in psychotherapy.

COMPASS hadron multiplicity measurements and fragmentation functions

International Nuclear Information System (INIS)

Stolarski, M.

2016-01-01

COMPASS is an experiment located at CERN SPS accelerator. For the results presented in this paper a 160 GeV positive muon beam was impinging on 6 LiD target. The COMPASS spectrometer was designed to reconstruct scattered muons and charged hadrons in a wide kinematic range. COMPASS preliminary results on hadron, pion and kaon multiplicities are presented. The hadron and pion data show a good agreement with (N)LO QCD expectations and some of these preliminary data have been already successfully incorporated in the global NLO QCD fits to world data. However, the results for kaon multiplicities, are different from the expectations of the DSS fit. There is also a tension between COMPASS and HERMES results, the only other experiment which measured kaon multiplicities in Semi-Inclusive Deep Inelastic scattering

To test a hypothetical path model evaluating the influence of type D personality on job stress and job satisfaction and to identify the mediating effects of compassion fatigue, burnout, and compassion satisfaction among clinical nurses in South Korea. Personalities susceptible to stress, compassion fatigue, and burnout in clinical nurses have negative effects on the job stress and job satisfaction. A correlational, cross-sectional design was used. A convenience sample of 875 clinical nurses was recruited between December 2014 - February 2015. The structured questionnaires included the Type D personality scale-14, Professional Quality of Life, job stress, job satisfaction, and general characteristics. To test the hypothetical path model, we performed a path analysis by using the AMOS 18·0 program. Based on the path model, type D personality was significantly associated with compassion fatigue, burnout, and compassion satisfaction in our study subjects. Type D personality was significantly associated with job stress and job satisfaction via the effect of burnout, compassion satisfaction, and job stress. Since type D personality is associated with job stress and job satisfaction, identifying personalities vulnerable to stress would help to address job stress and to enhance job satisfaction when nurses have a high level of compassion fatigue and burnout and a low level of compassion satisfaction. The development of interventions that can reduce negative affect and social inhibition of nurses with type D personality and investigation of methods to decrease their compassion fatigue and burnout and to increase compassion satisfaction should be encouraged. © 2016 John Wiley & Sons Ltd.

Self-compassion training for binge eating disorder: a pilot randomized controlled trial.

Science.gov (United States)

Kelly, Allison C; Carter, Jacqueline C

2015-09-01

The present pilot study sought to compare a compassion-focused therapy (CFT)-based self-help intervention for binge eating disorder (BED) to a behaviourally based intervention. Forty-one individuals with BED were randomly assigned to 3 weeks of food planning plus self-compassion exercises; food planning plus behavioural strategies; or a wait-list control condition. Participants completed weekly measures of binge eating and self-compassion; pre- and post-intervention measures of eating disorder pathology and depressive symptoms; and a baseline measure assessing fear of self-compassion. Results showed that: (1) perceived credibility, expectancy, and compliance did not differ between the two interventions; (2) both interventions reduced weekly binge days more than the control condition; (3) the self-compassion intervention reduced global eating disorder pathology, eating concerns, and weight concerns more than the other conditions; (4) the self-compassion intervention increased self-compassion more than the other conditions; and (5) participants low in fear of self-compassion derived significantly more benefits from the self-compassion intervention than those high in fear of self-compassion. Findings offer preliminary support for the usefulness of CFT-based interventions for BED sufferers. Results also suggest that for individuals to benefit from self-compassion training, assessing and lowering fear of self-compassion will be crucial. Individuals with BED perceive self-compassion training self-help interventions, derived from CFT, to be as credible and as likely to help as behaviourally based interventions. The cultivation of self-compassion may be an effective approach for reducing binge eating, and eating, and weight concerns in individuals with BED. Teaching individuals with BED CFT-based self-help exercises may increase their self-compassion levels over a short period of time. It may be important for clinicians to assess and target clients' fear of self-compassion

Full Text Available Satellite based navigation systems (GPS are widely used for ground, air and marine navigation. In the case of a malfunction or satellite signal inaccessibility, some back-up navigation system is needed. An electronic compass can provide this function. The compass module described in this paper is designed for precise navigation purposes. The compass module is equipped with electronic tilt error compensation, and includes everything in one package – electronics with digital output, sensors. A typical application of this compass is in underground drilling. A critical parameter in this application is heading accuracy. A reading error of 1 degree can cause a displacement of 1.8 metres in the target area (length of tunnel 100 m. This is not acceptable in an urban conglomeration, and therefore a more accurate heading sensing device must be used. An improved version of this electronic compass is being finished.

Stellar, Jennifer E; Manzo, Vida M; Kraus, Michael W; Keltner, Dacher

2012-06-01

Previous research indicates that lower-class individuals experience elevated negative emotions as compared with their upper-class counterparts. We examine how the environments of lower-class individuals can also promote greater compassionate responding-that is, concern for the suffering or well-being of others. In the present research, we investigate class-based differences in dispositional compassion and its activation in situations wherein others are suffering. Across studies, relative to their upper-class counterparts, lower-class individuals reported elevated dispositional compassion (Study 1), as well as greater self-reported compassion during a compassion-inducing video (Study 2) and for another person during a social interaction (Study 3). Lower-class individuals also exhibited heart rate deceleration-a physiological response associated with orienting to the social environment and engaging with others-during the compassion-inducing video (Study 2). We discuss a potential mechanism of class-based influences on compassion, whereby lower-class individuals' are more attuned to others' distress, relative to their upper-class counterparts.

Lateralization of the Avian Magnetic Compass: Analysis of Its Early Plasticity

Directory of Open Access Journals (Sweden)

Dennis Gehring

2017-05-01

Full Text Available In European Robins, Erithacus rubecula, the magnetic compass is lateralized in favor of the right eye/left hemisphere of the brain. This lateralization develops during the first winter and initially shows a great plasticity. During the first spring migration, it can be temporarily removed by covering the right eye. In the present paper, we used the migratory orientation of robins to analyze the circumstances under which the lateralization can be undone. Already a period of 1½ h being monocularly left-eyed before tests began proved sufficient to restore the ability to use the left eye for orientation, but this effect was rather short-lived, as lateralization recurred again within the next 1½ h. Interpretable magnetic information mediated by the left eye was necessary for removing the lateralization. In addition, monocularly, the left eye seeing robins could adjust to magnetic intensities outside the normal functional window, but this ability was not transferred to the “right-eye system”. Our results make it clear that asymmetry of magnetic compass perception is amenable to short-term changes, depending on lateralized stimulation. This could mean that the left hemispheric dominance for the analysis of magnetic compass information depends on lateralized interhemispheric interactions that in young birds can swiftly be altered by environmental effects.

Inclination Mixing in the Classical Kuiper Belt

Volk, Kathryn; Malhotra, Renu

2011-07-01

We investigate the long-term evolution of the inclinations of the known classical and resonant Kuiper Belt objects (KBOs). This is partially motivated by the observed bimodal inclination distribution and by the putative physical differences between the low- and high-inclination populations. We find that some classical KBOs undergo large changes in inclination over gigayear timescales, which means that a current member of the low-inclination population may have been in the high-inclination population in the past, and vice versa. The dynamical mechanisms responsible for the time variability of inclinations are predominantly distant encounters with Neptune and chaotic diffusion near the boundaries of mean motion resonances. We reassess the correlations between inclination and physical properties including inclination time variability. We find that the size-inclination and color-inclination correlations are less statistically significant than previously reported (mostly due to the increased size of the data set since previous works with some contribution from inclination variability). The time variability of inclinations does not change the previous finding that binary classical KBOs have lower inclinations than non-binary objects. Our study of resonant objects in the classical Kuiper Belt region includes objects in the 3:2, 7:4, 2:1, and eight higher-order mean motion resonances. We find that these objects (some of which were previously classified as non-resonant) undergo larger changes in inclination compared to the non-resonant population, indicating that their current inclinations are not generally representative of their original inclinations. They are also less stable on gigayear timescales.

Teaching Compassion in Prison: A Key to Learning

Directory of Open Access Journals (Sweden)

Em Strang

2015-12-01

Full Text Available In a project with long-term prisoners at HMP Dumfries, Scotland, tutors and students explore the notion and application of compassion, focusing in particular on the ways in which understanding compassion enables learning – not just the learning of academic subjects but also of interpersonal skills and emotional intelligence. The project highlights the benefits of teaching a so-called extracurricular subject, at the same time as revealing its centrality to learning in the first place. A lack of adequate teaching time in prison, and the fact that compassion is not considered a core subject in education, are both cited as obstacles in consolidating the work of the project. The benefits of teaching compassion - emotional, intellectual and spiritual - was made clear through written and verbal student feedback. Three short workshops highlighted the enormous potential in developing and establishing compassion as both subject and practice in prison education. It is hoped that practitioners and researchers will support the expansion of this work throughout prisons.

Compassion fatigue describes a work-related stress response in healthcare providers that is considered a 'cost of caring' and a key contributor to the loss of compassion in healthcare. The purpose of this review was to critically examine the construct of compassion fatigue and to determine if it is an accurate descriptor of work-related stress in healthcare providers and a valid target variable for intervention. Meta-narrative review. PubMed, Medline, CINAHL, PsycINFO, and Web of Science databases, Google Scholar, the grey literature, and manual searches of bibliographies. Seminal articles and theoretical and empirical studies on compassion fatigue in the healthcare literature were identified and appraised for their validity and relevance to our review. Sources were mapped according to the following criteria: 1) definitions; 2) conceptual analyses; 3) signs and symptoms; 4) measures; 5) prevalence and associated risk factors; and 6) interventions. A narrative account of included studies that critically examines the concept of compassion fatigue in healthcare was employed, and recommendations for practice, policy and further research were made. 90 studies from the nursing literature and healthcare in general were included in the review. Findings emphasized that the physical, emotional, social and spiritual health of healthcare providers is impaired by cumulative stress related to their work, which can impact the delivery of healthcare services; however, the precise nature of compassion fatigue and that it is predicated on the provision of compassionate care is associated with significant limitations. The conceptualization of compassion fatigue was expropriated from crisis counseling and psychotherapy and focuses on limited facets of compassion. Empirical studies primarily measure compassion fatigue using the Professional Quality of Life Scale, which does not assess any of the elements of compassion. Reported risk factors for compassion fatigue include job

To explore compassion fatigue and compassion satisfaction with the potential contributing factors of anxiety, depression and stress. To date, no studies have connected the quality of work-life with other contributing and co-existing factors such as depression, anxiety and stress. A self-report exploratory cross sectional survey of 132 nurses working in a tertiary hospital. The reflective assessment risk profile model provides an excellent framework for examining the relationships between the professional quality of work factors and contributing factors within the established risk profiles. The results show a definite pattern of risk progression for the six factors examined for each risk profile. Additionally, burnout and secondary traumatic stress were significantly related to higher anxiety and depression levels. Higher anxiety levels were correlated with nurses who were younger, worked full-time and without a postgraduate qualification. Twenty percent had elevated levels of compassion fatigue: 7.6% having a very distressed profile. At-risk nurses' stress and depression scores were significantly higher than nurses with higher compassion satisfaction scores. The employed nurse workforce would benefit from a psychosocial capacity building intervention that reduces a nurse's risk profile, thus enhancing retention. © 2013 John Wiley & Sons Ltd.

Quality of working life includes elements such as autonomy, trust, ergonomics, participation, job complexity, and work-life balance. The overarching aim of this study was to investigate if and how quality of working life affects Compassion Fatigue, Burnout, and Compassion Satisfaction among mental health practitioners. Staff working in three Italian Mental Health Departments completed the Professional Quality of Life Scale, measuring Compassion Fatigue, Burnout, and Compassion Satisfaction, and the Quality of Working Life Questionnaire. The latter was used to collect socio-demographics, occupational characteristics and 13 indicators of quality of working life. Multiple regressions controlling for other variables were undertaken to predict Compassion Fatigue, Burnout, and Compassion Satisfaction. Four hundred questionnaires were completed. In bivariate analyses, experiencing more ergonomic problems, perceiving risks for the future, a higher impact of work on life, and lower levels of trust and of perceived quality of meetings were associated with poorer outcomes. Multivariate analysis showed that (a) ergonomic problems and impact of work on life predicted higher levels of both Compassion Fatigue and Burnout; (b) impact of life on work was associated with Compassion Fatigue and lower levels of trust and perceiving more risks for the future with Burnout only; (c) perceived quality of meetings, need of training, and perceiving no risks for the future predicted higher levels of Compassion Satisfaction. In order to provide adequate mental health services, service providers need to give their employees adequate ergonomic conditions, giving special attention to time pressures. Building trustful relationships with management and within the teams is also crucial. Training and meetings are other important targets for potential improvement. Additionally, insecurity about the future should be addressed as it can affect both Burnout and Compassion Satisfaction. Finally

Compassion has long been regarded as a core part of our humanity by contemplative traditions, and in recent years, it has received growing research interest. Following a recent review of existing conceptualisations, compassion has been defined as consisting of the following five elements: 1) recognising suffering, 2) understanding the universality of suffering in human experience, 3) feeling moved by the person suffering and emotionally connecting with their distress, 4) tolerating uncomfortable feelings aroused (e.g., fear, distress) so that we remain open to and accepting of the person suffering, and 5) acting or being motivated to act to alleviate suffering. As a prerequisite to developing a high quality compassion measure and furthering research in this field, the current study empirically investigated the factor structure of the five-element definition using a combination of existing and newly generated self-report items. This study consisted of three stages: a systematic consultation with experts to review items from existing self-report measures of compassion and generate additional items (Stage 1), exploratory factor analysis of items gathered from Stage 1 to identify the underlying structure of compassion (Stage 2), and confirmatory factor analysis to validate the identified factor structure (Stage 3). Findings showed preliminary empirical support for a five-factor structure of compassion consistent with the five-element definition. However, findings indicated that the 'tolerating' factor may be problematic and not a core aspect of compassion. This possibility requires further empirical testing. Limitations with items from included measures lead us to recommend against using these items collectively to assess compassion. Instead, we call for the development of a new self-report measure of compassion, using the five-element definition to guide item generation. We recommend including newly generated 'tolerating' items in the initial item pool, to determine

Self-compassion has demonstrated many psychological benefits (Neff, 2009). In an effort to explore self-compassion as a potential resource for young women athletes, we explored relations among self-compassion, proneness to self-conscious emotions (i.e., shame, guilt-free shame, guilt, shame-free guilt, authentic pride, and hubristic pride), and potentially unhealthy self-evaluative thoughts and behaviors (i.e., social physique anxiety, obligatory exercise, objectified body consciousness, fear of failure, and fear of negative evaluation). Young women athletes (N = 151; Mage = 15.1 years) participated in this study. Self-compassion was negatively related to shame proneness, guilt-free shame proneness, social physique anxiety, objectified body consciousness, fear of failure, and fear of negative evaluation. In support of theoretical propositions, self-compassion explained variance beyond self-esteem on shame proneness, guilt-free shame proneness, shame-free guilt proneness, objectified body consciousness, fear of failure, and fear of negative evaluation. Results suggest that, in addition to self-esteem promotion, self-compassion development may be beneficial in cultivating positive sport experiences for young women.

The study aimed to explore measurable compassion competence among nurses and to examine the relationships between nurses' compassion competence and levels of compassion satisfaction, compassion fatigue and secondary traumatic stress. Compassion is a vital asset in the nursing profession. It is necessary to explore whether compassion competence is a factor influencing professional quality of life. This study utilized a multicenter descriptive cross-sectional survey. Data were collected from 680 nurses. Professional quality of life based on nurses' general characteristics showed a significant difference in the subjects' age, marital status, education, and total clinical experience. In addition, compassion competence had a significant positive correlation with compassion satisfaction and STS, whereas it had a significant negative correlation with burnout. Compassion competence was a factor influencing compassion satisfaction and burnout in professional quality of life. Our study included nurses with at least 1 year of clinical experience in a single cultural area, which limits its widespread applicability. To improve generalizability, future studies should include clinical nurses of various races, working in diverse cultural areas and with various levels of experience (including entry-level nurses and nursing students). Compassion competence of clinical nurses was a predictive factor for professional quality of life. Hospital administrators, nurse leaders and policy makers should develop and adopt nurse-retaining strategies that focus on improving nurses' compassion competence in order to reduce their burnout. We recommend the development of educational programmes to improve nurses' compassion competence and thereby enhance their professional quality of life. © 2016 International Council of Nurses.

Deeply Virtual Compton Scattering is a clean way to access the Generalized Parton Distributions of the proton. This paper deals with a possibility to perform such an experiment with the COMPASS apparatus which allows to access a large rang in $x_{Bj}$(0.03 to 0.25) and $Q^{2}$(1.5 to 7.5 GeV$^{2}$). A possible design for a recoil detector which is necessary to complement the COMPASS setup, is presented. Preliminary results on exclusive $]rho^{0}$ production from the COMPASS 2002 run are given. They look promising for future studies of deep $\\rho^{0}$ production.

2015-01-01

One of the important objectives of the COMPASS experiment is the exploration of transverse spin structure of nucleon via spin (in)dependent azimuthal asymmetries in semi-inclusive deep inelastic scattering (SIDIS) of polarized leptons (and soon also Drell-Yan (DY) reactions with $\\pi^-$) off transversely polarized target. For this purpose a series of measurements were made in COMPASS, using 160 GeV/c longitudinally polarized muon beam and polarized $^6LiD$ and $NH_3$ targets and are foreseen with 190 GeV/c $\\pi^-$ beam on polarized $NH_3$. The experimental results obtained by COMPASS for azimuthal effects in SIDIS play an important role in the general understanding of the three-dimensional nature of the nucleon and are widely used in theoretical analyses and global data fits. Future first ever polarized DY-data from COMPASS compared with SIDIS results will open a new chapter probing general principles of QCD TMD-formalism. In this review main focus will be given to the very recent COMPASS results obtained for...

The COMPASS II started at 2012 that includes polarized Drell-Yan program with a polarized solid target. The availability of pion beam provides an access to the Drell-Yan physics throughout the process where quark(target)-antiquark(beam) pair annihilates electromagnetically with a production of dilepton pair. Study of angular dependencies of the Drell-Yan process cross-section allows us to access to parton distribution functions (PDFs) or, more precisely, a convolutions of various PDFs. The transversely polarized target together with negative pion beam is an important feature of the COMPASS Drell-Yan experiment, that provides us with unique data on transverse momentum dependent (TMD) PDFs. After a plot run in 2014, the experiment has just started in 2015. The role of the Drell-Yan experiment at COMPASS in TMD PDFs study, with a comparison to semi-inclusive deep inelastic scattering experiment, is described. The experimental set-up, the status of the data taking in 2015 and preliminary analysis results in the 2...

How do the substrate reaction forces acting on a gecko's limbs respond to inclines?

Science.gov (United States)

Wang, Zhouyi; Dai, Zhendong; Li, Wei; Ji, Aihong; Wang, Wenbao

2015-02-01

Locomotion is an essential character of animals, and excellent moving ability results from the delicate sensing of the substrate reaction forces (SRF) acting on body and modulating the behavior to adapt the motion requirement. The inclined substrates present in habitats pose a number of functional challenges to locomotion. In order to effectively overcome these challenges, climbing geckos execute complex and accurate movements that involve both the front and hind limbs. Few studies have examined gecko's SRF on steeper inclines of greater than 90°. To reveal how the SRFs acting on the front and hind limbs respond to angle incline changes, we obtained detailed measurements of the three-dimensional SRFs acting on the individual limbs of the tokay gecko while it climbed on an inclined angle of 0-180°. The fore-aft forces acting on the front and hind limbs show opposite trends on inverted inclines of greater than 120°, indicating propulsion mechanism changes in response to inclines. When the incline angles change, the forces exerted in the normal and fore-aft directions by gecko's front and hind limbs are reassigned to take full advantage of limbs' different roles in overcoming resistance and in propelling locomotion. This also ensures that weight acts in the angle range between the forces generated by the front and hind limbs. The change in the distribution of SRF with a change in the incline angle is directly linked to the favorable trade-off between locomotive maneuverability and stability.

PRECISE TULLY-FISHER RELATIONS WITHOUT GALAXY INCLINATIONS

Power-law relations between tracers of baryonic mass and rotational velocities of disk galaxies, so-called Tully-Fisher relations (TFRs), offer a wealth of applications in galaxy evolution and cosmology. However, measurements of rotational velocities require galaxy inclinations, which are difficult to measure, thus limiting the range of TFR studies. This work introduces a maximum likelihood estimation (MLE) method for recovering the TFR in galaxy samples with limited or no information on inclinations. The robustness and accuracy of this method is demonstrated using virtual and real galaxy samples. Intriguingly, the MLE reliably recovers the TFR of all test samples, even without using any inclination measurements—that is, assuming a random sin i-distribution for galaxy inclinations. Explicitly, this 'inclination-free MLE' recovers the three TFR parameters (zero-point, slope, scatter) with statistical errors only about 1.5 times larger than the best estimates based on perfectly known galaxy inclinations with zero uncertainty. Thus, given realistic uncertainties, the inclination-free MLE is highly competitive. If inclination measurements have mean errors larger than 10°, it is better not to use any inclinations than to consider the inclination measurements to be exact. The inclination-free MLE opens interesting perspectives for future H I surveys by the Square Kilometer Array and its pathfinders.

Cancer is a leading cause of death worldwide. Given the complexity of caring work, recent studies have focused on the professional quality of life of oncology nurses. China, the world's largest developing country, faces heavy burdens of care for cancer patients. Chinese oncology nurses may be encountering the negative side of their professional life. However, studies in this field are scarce, and little is known about the prevalence and predictors of oncology nurses' professional quality of life. To describe and explore the prevalence of predictors of professional quality of life (compassion fatigue, burnout and compassion satisfaction) among Chinese oncology nurses under the guidance of two theoretical models. A cross-sectional design with a survey. Ten tertiary hospitals and five secondary hospitals in Shanghai, China. A convenience and cluster sample of 669 oncology nurses was used. All of the nurses worked in oncology departments and had over 1 year of oncology nursing experience. Of the selected nurses, 650 returned valid questionnaires that were used for statistical analyses. The participants completed the demographic and work-related questionnaire, the Chinese version of the Professional Quality of Life Scale for Nurses, the Chinese version of the Jefferson Scales of Empathy, the Simplified Coping Style Questionnaire, the Perceived Social Support Scale, and the Chinese Big Five Personality Inventory brief version. Descriptive statistics, t-tests, one-way analysis of variance, simple and multiple linear regressions were used to determine the predictors of the main research variables. Higher compassion fatigue and burnout were found among oncology nurses who had more years of nursing experience, worked in secondary hospitals and adopted passive coping styles. Cognitive empathy, training and support from organizations were identified as significant protectors, and 'perspective taking' was the strongest predictor of compassion satisfaction, explaining 23.0% of

Exploration of transverse spin structure of the nucleon via study of the spin (in)dependent azimuthal asymmetries in semi-inclusive deep inelastic scattering (SIDIS) and Drell-Yan (DY) reactions is one of the main aspects of the broad physics program of the COMPASS experiment (CERN, Switzerland). In past decade COMPASS has collected a considerable amount of polarized deuteron and proton SIDIS data while 2014 and 2015 runs were dedicated to the Drell-Yan measurements. Results on SIDIS azimuthal effects provided so far by COMPASS play an important role in general understanding of the three-dimensional nature of the nucleon. Giving access to the entire "twist-2" set of transverse momentum dependent (TMD) parton distribution functions (PDFs) and fragmentation functions (FFs) COMPASS data are being widely used in phenomenological analyses and experimental data fits. Recent unique and first ever x-$Q^{2}$-z-pT multidimensional results for transverse spin asymmetries obtained by COMPASS serve as a direct and unprece...

In this study, we aimed to measure the inclination of teeth on dental casts by a manual technique with the tooth inclination protractor (TIP; MBI, Newport, United Kingdom) and a newly designed 3-dimensional (3D) software program. The correlation of the 2 techniques was evaluated, and the reliability of each technique was assessed separately. This study was conducted on 36 dental casts of normal, well-aligned Class I occlusions; we assessed 432 teeth. All casts had a normal Class I occlusion. After determining the facial axis of the clinical crown and the facial axis points on the dental casts, we measured the inclinations of the incisors and posterior teeth up to the first molars in each dental arch relative to Andrews' occlusal plane and the posterior occlusal plane using the TIP. Moreover, the casts were scanned by a structured-light 3D scanner. The inclination of teeth relative to the occlusal plane was determined using the new software. To assess the reliability, measurements of all teeth from 15 casts were repeated twice by the 2 methods. Intraclass correlation coefficient and Dahlberg's formula were used for calculation of correlation and reliability. Overall, the 2 techniques were not significantly different in the measurements of the inclinations of the teeth in both jaws. The ranges of Dahlberg's formula were 3.1° to 5.8° for the maxilla and 3.3° to 5.9° for the mandible. The overall correlation of the 2 techniques according to the intraclass correlation coefficient was 0.91. For calculation of reliability, the intraclass correlation coefficients for the TIP and the 3D method were 0.73 and 0.82, respectively. The TIP and the 3D software showed a high correlation for measurement of the inclinations of maxillary and mandibular teeth relative to the occlusal plane. Also, the reproducibility of the measurements in each method was high. Copyright © 2014 American Association of Orthodontists. Published by Elsevier Inc. All rights reserved.

Quark fragmentation functions (FF) D{sub q}{sup h}(z,Q{sup 2}) describe final-state hadronization of quarks q into hadrons h. The FFs can be extracted from hadron multiplicities produced in semi-inclusive deep inelastic scattering. The COMPASS collaboration has recently measured charged hadron multiplicities for identified pions and kaons using a 160 GeV/c muon beam impinging on an iso-scalar target. The data cover a large kinematical range and provide an important input for global QCD analyses of world data at NLO, aiming at the determination of FFs in particular in the strange quark sector. The newest results from COMPASS on pion and kaon multiplicities will be presented.

Exploring Magnetic Fields with a Compass

Science.gov (United States)

Lunk, Brandon; Beichner, Robert

2011-01-01

A compass is an excellent classroom tool for the exploration of magnetic fields. Any student can tell you that a compass is used to determine which direction is north, but when paired with some basic trigonometry, the compass can be used to actually measure the strength of the magnetic field due to a nearby magnet or current-carrying wire. In this paper, we present a series of simple activities adapted from the Matter & Interactions textbook for doing just this. Interestingly, these simple measurements are comparable to predictions made by the Bohr model of the atom. Although antiquated, Bohr's atom can lead the way to a deeper analysis of the atomic properties of magnets. Although originally developed for an introductory calculus-based course, these activities can easily be adapted for use in an algebra-based class or even at the high school level.

Full Text Available Abstract This study investigated relationships between self-compassion, self-efficacy, and self-esteem, as well as age and sex differences and other sociodemographic variables in relation to self-compassion. Four-hundred and thirty-two Brazilian adults (50% women from nearly all country states participated in the study filling out a sociodemographic survey and three scales: self-compassion, self-efficacy, and self-esteem. Comparisons of means between self-compassion and pairs of groups designed by sociodemographic data showed higher self-compassion in men, people aged from 31 to 66 years-old, not under psychiatric medication, without a job, and with children. Results also showed that self-compassion is highly correlated with self-esteem and self-efficacy. We highlight that results are sample dependent and further studies on self-compassion need to be conducted in Brazil.

Affective and physiological responses to the suffering of others: compassion and vagal activity.

Science.gov (United States)

Stellar, Jennifer E; Cohen, Adam; Oveis, Christopher; Keltner, Dacher

2015-04-01

Compassion is an affective response to another's suffering and a catalyst of prosocial behavior. In the present studies, we explore the peripheral physiological changes associated with the experience of compassion. Guided by long-standing theoretical claims, we propose that compassion is associated with activation in the parasympathetic autonomic nervous system through the vagus nerve. Across 4 studies, participants witnessed others suffer while we recorded physiological measures, including heart rate, respiration, skin conductance, and a measure of vagal activity called respiratory sinus arrhythmia (RSA). Participants exhibited greater RSA during the compassion induction compared with a neutral control (Study 1), another positive emotion (Study 2), and a prosocial emotion lacking appraisals of another person's suffering (Study 3). Greater RSA during the experience of compassion compared with the neutral or control emotion was often accompanied by lower heart rate and respiration but no difference in skin conductance. In Study 4, increases in RSA during compassion positively predicted an established composite of compassion-related words, continuous self-reports of compassion, and nonverbal displays of compassion. Compassion, a core affective component of empathy and prosociality, is associated with heightened parasympathetic activity. (c) 2015 APA, all rights reserved).

Hadron Spectroscopy with COMPASS – Newest Results

Directory of Open Access Journals (Sweden)

Nerling Frank

2012-12-01

Full Text Available The COMPASS experiment at the CERN SPS investigates the structure and spectrum of hadrons by scattering high energetic hadrons and polarised muons off various fixed targets. During the years 2002–2007, COMPASS focused on nucleon spin physics using 160 GeV/c polarised µ+ beams on polarised deuteron and proton targets, including measurements of the gluon contribution to the nucleon spin using longitudinal target polarisation as well as studies of transverse spin effects in the nucleon on a transversely polarised target. One major goal of the physics programme using hadron beams is the search for new states, in particular the search for JPC exotic states and glue-balls. COMPASS measures not only charged but also neutral final-state particles, allowing for investigation of new objects in different reactions and decay channels. In addition COMPASS can measure low-energy QCD constants like, e.g. the electromagnetic polarisability of the pion. Apart from a few days pilot run data taken in 2004 with a 190 GeV/c π− beam on a Pb target, showing a significant spin-exotic JPC = 1−+ resonance at around 1660 MeV/c2, COMPASS collected high statistics with negative and positive 190 GeV/c hadron beams on a proton (H2 and nuclear (Ni, Pb targets in 2008 and 2009. We give a selected overview of the newest results and discuss the status of various ongoing analyses.

The desired moral attitude of the physician: (II) compassion.

Science.gov (United States)

Gelhaus, Petra

2012-11-01

Professional medical ethics demands of health care professionals in addition to specific duties and rules of conduct that they embody a responsible and trustworthy personality. In the public discussion, different concepts are suggested to describe the desired implied attitude of physicians. In a sequel of three articles, a set of three of these concepts is presented in an interpretation that is meant to characterise the morally emotional part of this attitude: "empathy", "compassion" and "care". In the first article of the series, "empathy" has been developed as a mainly cognitive and morally neutral capacity of understanding. In this article, the emotional and virtuous core of the desired professional attitude-compassion-is elaborated. Compassion is distinguished from sympathy, empathy and pity. Several problems of compassion as a spontaneous, warm emotion for being a professional virtue are discussed: especially questions of over-demand, of justice and of concerns because of a possible threat to the patient's dignity and autonomy. An interpretation of compassion as processed and learned professional attitude, that founds dignity on the general idea of man as a sentient being and on solidarity, not on his independence and capacities, is developed. It is meant to rule out the possible side effects and to make compassion as a professional attitude and as professional virtue attractive, teachable and acquirable. In order to reach the adequate warmth and closeness for the particular physician-patient-relation, professional compassion has to be combined with the capacity of empathy. If appropriate, the combination of both empathy and compassion as "empathic compassion" can demand a much warmer attitude towards the patient than each of the elements alone, or the simple addition of them can provide. The concept of "care" that will be discussed in a forthcoming article of this sequel is a missing necessary part to describe the active potential of the desired moral

Full Text Available Context: This critical reflection is set in the context of increasing marketisation in UK higher education, where students are seen as consumers, rather than learners with power. The paper explores the dark side of academic work and the compassion gap in universities, in order to make recommendations for practice development in higher education and the human services. Aims: The paper aims to show how reflexive dialogue can be used to enable the development of compassionate academic practice. Conclusions and implications for practice: Toxic environments and organisational cultures in higher education have compounded the crisis in compassionate care in the NHS. Implications for practice are: Narrative approaches and critical appreciative inquiry are useful methods with which to reveal, and rectify, failures of compassion Courageous conversations are required to challenge dysfunctional organisational systems and processes Leadership development programmes should include the application of skills of compassion in organisational settings

Compassion, the emotional response of caring for another who is suffering and that results in motivation to relieve suffering, is thought to be an emotional antecedent to altruistic behavior. However, it remains unclear whether compassion enhances altruistic behavior in a uniform way or is specific to sub-types of behavior such as altruistic helping of a victim or altruistic punishment of a transgressor. We investigated the relationship between compassion and subtypes of altruistic behavior using third-party paradigms where participants (1) witnessed an unfair economic exchange between a transgressor and a victim, and (2) had the opportunity to either spend personal funds to either economically (a) help the victim or (b) punish the transgressor. In Study 1, we examined whether individual differences in self-reported empathic concern (the emotional component of compassion) was associated with greater altruistic helping or punishment behavior in two independent samples. For participants who witnessed an unfair transaction, trait empathic concern was associated with greater helping of a victim and had no relationship to punishment. However, in those who decided to punish the transgressor, participants who reported greater empathic concern decided to punish less. In Study 2, we directly enhanced compassion using short-term online compassion meditation training to examine whether altruistic helping and punishment were increased after two weeks of training. Compared to an active reappraisal training control group, the compassion training group gave more to help the victim and did not differ in punishment of the transgressor. Together, these two studies suggest that compassion is related to greater altruistic helping of victims and is not associated with or may mitigate altruistic punishment of transgressors.

Previous studies suggest that self-compassion is related to numerous facets of mental health, but the role of cognitions in this relationship remains unknown. To examine the mediating role of cognitions in the relationship between self-compassion and anxiety, depression, and life satisfaction when controlling for self-esteem in Japanese people, we conducted two studies. Study 1 (N = 231) examined the relationship between self-compassion and affect by modeling negative automatic thoughts as a mediator; Study 2 (N = 233) tested whether positive and negative automatic thoughts meditate this relationship. Results suggested that both self-compassion and self-esteem increased positive automatic thoughts and decreased trait anxiety, whereas only self-esteem increased life satisfaction and decreased depression directly. Positive automatic thoughts increased life satisfaction and decreased depression and trait anxiety, and positive automatic thoughts mediated the relationship between self-compassion and negative affect. These findings suggest that both positive and negative automatic thoughts mediate the relationship between self-compassion and affect in Japanese people. PMID:25395717

Self-compassion is thought to protect from body image concerns. However, the mechanisms of this effect remain unclear. This study examined three positive dimensions of self-compassion as moderators of the mediated relationship between perceived overweight status, appearance comparison, and appearance esteem. A sample of 232 youth aged 13-18 years, mean=18.36 (SD=1.5) years, reported on appearance esteem, appearance comparison, perceived weight status, and self-compassion dimensions including self-kindness, common humanity, and mindfulness. Among boys, mindfulness and common humanity moderated the perceived weight status to appearance comparison pathway of the mediation (ps=.01), such that this relationship was weaker among boys with higher levels of these dimensions of self-compassion. These findings were not replicated among girls. None of the self-compassion dimensions moderated the appearance comparison to appearance esteem pathway. Self-compassion dimensions that decrease the focus on the self may protect against body image concerns among boys. Copyright © 2017 Elsevier Ltd. All rights reserved.

Helping the self help others: self-affirmation increases self-compassion and pro-social behaviors.

Reflecting on an important personal value in a self-affirmation activity has been shown to improve psychological functioning in a broad range of studies, but the underlying mechanisms for these self-affirmation effects are unknown. Here we provide an initial test of a novel self-compassion account of self-affirmation in two experimental studies. Study 1 shows that an experimental manipulation of self-affirmation (3-min of writing about an important personal value vs. writing about an unimportant value) increases feelings of self-compassion, and these feelings in turn mobilize more pro-social behaviors to a laboratory shelf-collapse incident. Study 2 tests and extends these effects by evaluating whether self-affirmation increases feelings of compassion toward the self (consistent with the self-compassion account) or increases feelings of compassion toward others (an alternative other-directed compassion account), using a validated storytelling behavioral task. Consistent with a self-compassion account, Study 2 demonstrates the predicted self-affirmation by video condition interaction, indicating that self-affirmation participants had greater feelings of self-compassion in response to watching their own storytelling performance (self-compassion) compared to watching a peer's storytelling performance (other-directed compassion). Further, pre-existing levels of trait self-compassion moderated this effect, such that self-affirmation increased self-compassionate responses the most in participants low in trait self-compassion. This work suggests that self-compassion may be a promising mechanism for self-affirmation effects, and that self-compassionate feelings can mobilize pro-social behaviors.

Against compassion: in defence of a "hybrid" concept of empathy.

Science.gov (United States)

Morgan, Alastair

2017-07-01

In this article, I argue that the recent emphasis on compassion in healthcare practice lacks conceptual richness and clarity. In particular, I argue that it would be helpful to focus on a larger concept of empathy rather than compassion alone and that compassion should be thought of as a component of this larger concept of empathy. The first part of the article outlines a critique of the current discourse of compassion on three grounds. This discourse naturalizes, individualizes, and reifies compassion leading to a decontextualized and simplified understanding of failures in healthcare practice. The second part uses resources from phenomenology and contemporary moral philosophy to construct a "hybrid" concept of empathy that includes both pre-reflective/intuitive and cognitive/imaginative components. This "hybrid" concept of empathy leads to a more complex understanding of the multiple responses to others' distress. I conclude that there are no straightforward normative naturalistic responses to others' distress. Rather than conceptualizing compassion as a naturalistic impulse or a character-based trait, we need to consider the complexity of our empathic recognition of vulnerable others. © 2016 John Wiley & Sons Ltd.

Compassion fatigue, burnout and compassion satisfaction in neonatologists in the US.

Compassion fatigue (CF) is distress experienced by caregivers from ongoing contact with patients who are suffering. Burnout (BO) is occupational stress directly related to dissonance between job demands and available resources. Compassion satisfaction (CS) is professional fulfillment experienced through helping others. CF in physicians is not well studied. Neonatologists may be at particular risk for CF by virtue of recurrent exposure to distress in patients and their families. The objectives of this study were to determine the prevalence of CF, BO and CS, and to identify potential predictors for these phenomena in neonatologists. A modified Compassion Fatigue and Satisfaction Self-Test and a questionnaire of professional details and personal characteristics were distributed electronically to neonatologists nationally. Multivariable logistic and linear regression models for CF, BO and CS as a function of potential predictors were constructed. The survey response rate was 47%. The prevalence of CF, BO and CS was 15.7, 20.8 and 21.9%, respectively. Female gender, emotional depletion, distress from 'a clinical situation', 'co-workers', 'personal health issues' and 'not talking about distressing issues' were each significant determinants of CF. Emotional depletion, distress from the 'physical work environment' and 'co-workers', and 'not talking about distressing issues' were significant determinants of BO. Self-identification as Hispanic; 'not currently feeling distressed'; talking about distressing issues; and utilization of pediatric palliative care services were significant determinants of higher CS. CF and BO may impact emotional well-being and professional performance of neonatologists. Enhancement of CS is a potential target for intervention.

Self-compassion facilitates health behavior self-regulation; few studies have examined self-compassion and exercise. This online, cross-sectional study investigated self-compassion's relationship with exercise self-regulation of an exercise setback. Adults (N = 105) who had experienced an exercise setback within the last 6 months completed baseline measures, recalled an exercise setback, and completed questionnaires assessing self-regulation in this context. Self-compassion associated with self-determined motivations and exercise goal reengagement, and negatively related to extrinsic motivations, state rumination, and negative affect. Self-compassion predicted unique variance, beyond self-esteem, in exercise goal reengagement, external regulation, state rumination, and negative affect experienced after an exercise setback. Self-compassion and self-esteem had unique relationships with goal reengagement, state rumination, and situational motivation, while having a complementary relationship with negative affect. This research adds to the few studies that examine the role of self-compassion in exercise self-regulation by examining how self-compassion and self-esteem relate to reactions to a recalled exercise setback.

Conclusion: As shown in the study, some of the undergraduate students are experiencing compassion fatigue and burnout, associated with relieving suffering of others. Therefore, knowledge of compassion fatigue and burnout and the coping strategies should be part of nursing training.

Radio-loudness in black hole transients: evidence for an inclination effect

Motta, S. E.; Casella, P.; Fender, R.

Accreting stellar-mass black holes appear to populate two branches in a radio:X-ray luminosity plane. We have investigated the X-ray variability properties of a large number of black hole low-mass X-ray binaries, with the aim of unveiling the physical reasons underlying the radio-loud/radio-quiet nature of these sources, in the context of the known accretion-ejection connection. A reconsideration of the available radio and X-ray data from a sample of black hole X-ray binaries confirms that being radio-quiet is the more normal mode of behaviour for black hole binaries. In the light of this we chose to test, once more, the hypothesis that radio loudness could be a consequence of the inclination of the X-ray binary. We compared the slope of the `hard-line' (an approximately linear correlation between X-ray count rate and rms variability, visible in the hard states of active black holes), the orbital inclination, and the radio-nature of the sources of our sample. We found that high-inclination objects show steeper hard-lines than low-inclination objects, and tend to display a radio-quiet nature (with the only exception of V404 Cyg), as opposed to low-inclination objects, which appear to be radio-loud(er). While in need of further confirmation, our results suggest that - contrary to what has been believed for years - the radio-loud/quiet nature of black-hole low mass X-ray binaries might be an inclination effect, rather than an intrinsic source property. This would solve an important issue in the context of the inflow-outflow connection, thus providing significant constraints to the models for the launch of hard-state compact jets.

The purpose of this qualitative study was to examine the treatment effectiveness of a multifaceted education program to decrease compassion fatigue (CF) and burnout (BO) symptoms and increase compassion satisfaction of emergency nurses participating in the training. The goal of the CF multifaceted intervention program was to demonstrate a statistically significant improvement in the 3 CF subscales: an increase on the Compassion Satisfaction (CS) subscale and a decrease on the Secondary Traumatic Stress (STS) and BO subscales in the participants' pretest and posttest scores as measured by The Professional Quality of Life test (B. H. , ). The study sites were 2 emergency departments in Colorado Springs, CO. A convenience sample consisted of emergency nurses who self-selected to participate in the study. Univariate statistics were used, and data were examined for normalcy of distribution. Because these data were not distributed normally, Wilcoxon signed-rank tests were used to evaluate the differences between the baseline and postintervention groups. The multifaceted education program resulted in a statistically significant increase in CS (p = 0.004) and a decrease in BO (p = 0.001 or less) and STS (p = 0.001) symptoms.

Self-compassion versus global self-esteem: two different ways of relating to oneself.

2009-02-01

This research examined self-compassion and self-esteem as they relate to various aspects of psychological functioning. Self-compassion entails treating oneself with kindness, recognizing one's shared humanity, and being mindful when considering negative aspects of oneself. Study 1 (N=2,187) compared self-compassion and global self-esteem as they relate to ego-focused reactivity. It was found that self-compassion predicted more stable feelings of self-worth than self-esteem and was less contingent on particular outcomes. Self-compassion also had a stronger negative association with social comparison, public self-consciousness, self-rumination, anger, and need for cognitive closure. Self-esteem (but not self-compassion) was positively associated with narcissism. Study 2 (N=165) compared global self-esteem and self-compassion with regard to positive mood states. It was found that the two constructs were statistically equivalent predictors of happiness, optimism, and positive affect. Results from these two studies suggest that self-compassion may be a useful alternative to global self-esteem when considering what constitutes a healthy self-stance.

We describe the method devised to reconstruct inclined cosmic-ray air showers with zenith angles greater than 60° detected with the surface array of the Pierre Auger Observatory. The measured signals at the ground level are fitted to muon density distributions predicted with atmospheric cascade models to obtain the relative shower size as an overall normalization parameter. The method is evaluated using simulated showers to test its performance. The energy of the cosmic rays is calibrated using a sub-sample of events reconstructed with both the fluorescence and surface array techniques. The reconstruction method described here provides the basis of complementary analyses including an independent measurement of the energy spectrum of ultra-high energy cosmic rays using very inclined events collected by the Pierre Auger Observatory.

Compassion as the reunion of feminine and masculine virtues in medicine.

2017-01-01

The central role of the virtue of compassion in the shaping of the professional character of healthcare providers is a well-emphasized fact. On the other hand, the utmost obligation of physicians is to alleviate or eliminate human suffering. Traditionally, according to the Aristotelian understanding of virtues and virtue ethics, human virtues have been associated with masculinity. In recent decades, the founders of the ethics of care have introduced a set of virtues with feminine nature. This paper analyzes the notion of compassion as a common virtue between the traditional/masculine and care/feminine sets of virtues and shows that compassion is a reunion and merging point of both sets of human virtues. This role can be actualized through the development and promotion of compassion as an important part of the character of an ideal physician/healthcare provider. In addition, this paper argues that the notion of compassion can shed light on some important aspects of the contemporary debates on healthcare provider-patient relationship and medical futility. Despite the recent technological and scientific transformations in medicine, the interpersonal relationship between healthcare providers and patients still plays a vital role in pursuing the goals of healthcare. The virtue of compassion plays a central role in the establishment of a trust-based physician-patient relationship. This central role is discernible in the debate of medical futility in which making difficult decisions, depends largely on trust and rapport which are achievable by compassion in the physician and the recognition of this compassion by the patients and their surrogate decision makers.

The capacity to work productively is a key component of health and emotional well-being. People who work in health care can be exposed to the fatigue of care. Compassion fatigue has been described as an occupational hazard specific to clinical work related severe emotional distress. In our study, we have evaluated compassion fatigue in a mental health group (47 psychiatric staff) and its relationship with inpatients (237 inpatients) affected by some psychiatric disorders. At baseline, the more significant data indicate a high percentage of Job Burnout and Compassion Fatigue in psychiatric nurses (respectively, 39.28%, 28.57%). Significant Compassion Fatigue percentage is present also in psychologist group (36.36%). Finally, in psychiatrists, the exposure to patients increased vicarious trauma (28.57%), but not job burnout. After a year of participation in Balint Groups, the psychiatric staff presented an overall reduction in total mean score in any administered scale (CBI: pfatigue causes concern among mental health professionals, and Balint Groups may represent a therapeutic strategy to help health professionals to face difficulties in challenging work environments.

Should intimates respond to their interpersonal mistakes with self-criticism or with self-compassion? Although it is reasonable to expect self-compassion to benefit relationships by promoting self-esteem, it is also reasonable to expect self-compassion to hurt relationships by removing intimates’ motivation to correct their interpersonal mistakes. Two correlational studies, 1 experiment, and 1 longitudinal study demonstrated that whether self-compassion helps or hurts relationships depends on the presence versus absence of dispositional sources of the motivation to correct interpersonal mistakes. Among men, the implications of self-compassion were moderated by conscientiousness. Among men high in conscientiousness, self-compassion was associated with greater motivation to correct interpersonal mistakes (Studies 1 and 3), observations of more-constructive problem-solving behaviors (Study 2), reports of more accommodation (Study 3), and fewer declines in marital satisfaction that were mediated by decreases in interpersonal problem severity (Study 4); among men low in conscientiousness, self-compassion was associated with these outcomes in the opposite direction. Among women, in contrast, likely because women are inherently more motivated than men to preserve their relationships for cultural and/or biological reasons, self-compassion was never harmful to the relationship. Instead, women’s self-compassion was positively associated with the motivation to correct their interpersonal mistakes (Study 1) and changes in relationship satisfaction (Study 4), regardless of conscientiousness. Accordingly, theoretical descriptions of the implications of self-promoting thoughts for relationships may be most complete to the extent that they consider the presence versus absence of other sources of the motivation to correct interpersonal mistakes.

A study of the passive gait of a compass-like biped robot: Symmetry and chaos

International Nuclear Information System (INIS)

Goswami, A.; Espiau, B.; Thuilot, B.

1998-01-01

The focus of this work is a systematic study of the passive gait of a compass-like planar, biped robot on inclined slopes. The robot is kinematically equivalent to a double pendulum, possessing two kneeless legs with point masses and a third point mass at the hip joint. Three parameters, namely, the ground-slope angle and the normalized mass and length of the robot describe its gait. The authors show that in response to a continuous change in any one of its parameters, the symmetric and steady stable gait of the unpowered robot gradually evolves through a regime of bifurcations characterized by progressively complicated asymmetric gaits, eventually arriving at an apparently chaotic gait where not two steps are identical. The robot can maintain this gait indefinitely. A necessary (but not sufficient) condition for the stability of such gaits is the contraction of the phase-fluid volume. For this frictionless robot, the volume contraction, which the authors compute, is caused by the dissipative effects of the ground-impact model. In the chaotic regime, the fractal dimension of the robot's strange attractor (2.07) compared to its state-space dimension (4) also reveals strong contraction. The authors present a novel graphical technique based on the first return map that compactly captures the entire evolution of the gait, from symmetry to chaos. Additional passive dissipative elements in the robot joint results in a significant improvement in the stability and the versatility of the gait, and provide a rich repertoire for simple controls laws

COMPASS is a fixed-target experiment at CERN SPS which investigates the structure and spectroscopy of hadrons. During in total 9 weeks in 2008 and 2009, a 190 GeV/c proton beam impinging on a liquid hydrogen target has been used primarily to study the production of exotic mesons and glueball candidates at central rapidities. As no bias on the rapidity was introduced by the trigger system, the data also yield the unique possibility to study diffractive dissociation of the beam proton while an inert target is assumed. To this end exclusive events with three charged particles including one proton in the final state have been extracted. We report on the status of the event selection studies and discuss the prospect of using partial wave analysis techniques, which have been successfully applied for diffractive dissociation reactions of pions in COMPASS.

The purpose of this study was to assess the degree of lower incisor inclination with respect to different reference planes. It was an observational, analytical, longitudinal, prospective study conducted on 100 lateral cephalograms which were corrected according to the photograph in natural head position in order to draw the true vertical plane (TVP). The incisor mandibular plane angle (IMPA) was compensated to eliminate the variation of the mandibular plane growth type with the formula "FMApx.- 25 (FMA) + IMPApx. = compensated IMPA (IMPACOM)". As the data followed normal distribution determined by the KolmogorovSmirnov test, parametric tests were used for the statistical analysis, Ttest, ANOVA and Pearson coefficient correlation test. Statistical analysis was performed using a statistical significance of p planes. There were statistically significant differences among the means of the planes measured, except for IMPACOM, FMIA and TVP. The IMPA differed significantly from the IMPACOM. The compensated IMPA and the FMIA did not differ significantly from the TVP. The true horizontal plane was mismatched with Frankfort plane in 84% of the sample with a range of 19°. The true vertical plane is adequate for measuring lower incisor inclination. Sociedad Argentina de Investigación Odontológica.

The emotion of compassion and the likelihood of its expression in nursing practice.

Newham, Roger Alan

2017-07-01

Philosophical and empirical work on the nature of the emotions is extensive, and there are many theories of emotions. However, all agree that emotions are not knee jerk reactions to stimuli and are open to rational assessment or warrant. This paper's focus is on the condition or conditions for compassion as an emotion and the likelihood that it or they can be met in nursing practice. Thus, it is attempting to keep, as far as possible, compassion as an emotion separate from both moral norms and professional norms. This is because empirical or causal conditions that can make experiencing and acting out of compassion difficult seem especially relevant in nursing practice. I consider how theories of emotion in general and of compassion in particular are somewhat contested, but all recent accounts agree that emotions are not totally immune to reason. Then, using accounts of constitutive conditions of the emotion of compassion, I will show how they are often likely to be quite fragile or unstable in practice and particularly so within much nursing practice. In addition, some of the conditions for compassion will be shown to be problematic for nursing practice. It is difficult to keep ideas of compassion separate from morality, and this connection is noticeable in the claims made of compassion for nursing and so I will briefly highlight one such connection that of the need for normative theory to give an account of the value that emotions such as compassion presume and that compassionate motivation is separate from moral motivation and may conflict with it. The fragility or instability of the emotion of compassion in practice has implications for both what can be expected and what should be expected of compassion; at least if what is wanted is a realist rather than idealist account of "should." © 2016 John Wiley & Sons Ltd.

This study investigated whether self-compassion and emotional invalidation (perceiving others as indifferent to one's emotions) may explain the relationship of childhood exposure to adverse parenting and adult psychopathology in psychiatric outpatients (N=326). Path analysis was used to investigate associations between exposure to adverse parenting (abuse and indifference), self-compassion, emotional invalidation, and mental health when controlling for gender and age. Self-compassion was strongly inversely associated with emotional invalidation, suggesting that a schema that others will be unsympathetic or indifferent toward one's emotions may affect self-compassion and vice versa. Both self-compassion and emotional invalidation mediated the relationship between parental indifference and mental health outcomes. These preliminary findings suggest the potential utility of self-compassion and emotional schemas as transdiagnostic treatment targets. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

The objectives of this study were to evaluate (1) the impact of maxillary incisor inclination on the aesthetics of the profile view of a smile, (2) to determine the most aesthetic inclination in the profile view of a smile and correlate it with facial features, and (3) to determine if dentists, orthodontists, and laypeople appreciate differently incisor inclination in smile aesthetics. A smiling profile photograph of a female subject (22 years of age) who fulfilled the criteria of soft tissue normative values and a balanced smile was obtained. The photograph was manipulated to simulate six lingual and labial inclinations at 5 degree increments to a maximum of 15 degrees. The seven photographs were randomly distributed in a binder to three groups of raters (30 dentists, 30 orthodontists, and 30 laypeople) who scored the attractiveness of the photographic variations using a visual analogue scale. Comparison of the mean scores was carried out by repeated analysis of variance, univariate tests, and multiple Bonferroni comparisons. The results showed a statistically significant interaction between the rater's profession and the aesthetic preference of incisor inclination (P = 0.013). The profile smile corresponding to an increase of 5 degrees in a labial direction had the highest score among all professions and among male and female raters. Orthodontists preferred labial crown torque; dentists and laypeople did not appreciate excessive incisor inclination in either the lingual or the labial directions. The most preferred smile matched with a maxillary incisor inclined 93 degrees to the horizontal line and +7 degrees to the lower facial third.

The neurobiological link between compassion and love

Esch, Tobias; Stefano, George B.

2011-01-01

Summary Love and compassion exert pleasant feelings and rewarding effects. Besides their emotional role and capacity to govern behavior, appetitive motivation, and a general ‘positive state’, even ‘spiritual’ at times, the behaviors shown in love and compassion clearly rely on neurobiological mechanisms and underlying molecular principles. These processes and pathways involve the brain’s limbic motivation and reward circuits, that is, a finely tuned and profound autoregulation. This capacity to self-regulate emotions, approach behaviors and even pair bonding, as well as social contact in general, i.e., love, attachment and compassion, can be highly effective in stress reduction, survival and overall health. Yet, molecular biology is the basis of interpersonal neurobiology, however, there is no answer to the question of what comes first or is more important: It is a cybernetic capacity and complex circuit of autoregulation that is clearly ‘amazing’.

Self-compassion involves being kind to oneself when challenged with personal weaknesses or hardship and has been claimed to be associated with resilience in various areas. So far, there are only a handful of studies that investigate self-compassion and its relation to clinical depression. Therefore, the principal goals of the present study were (a) to compare self-compassion in clinically depressed patients and never-depressed subjects, (b) to investigate self-compassion and its relation to cognitive-behavioral avoidance and rumination in depressed outpatients, and (c) to investigate rumination and avoidance as mediators of the relationship between self-compassion and depressive symptoms. One hundred and forty-two depressed outpatients and 120 never-depressed individuals from a community sample completed a self-report measure of self-compassion along with other measures. Results indicate that depressed patients showed lower levels of self-compassion than never-depressed individuals, even when controlled for depressive symptoms. In depressed outpatients, self-compassion was negatively related to depressive symptoms, symptom-focused rumination, as well as cognitive and behavioral avoidance. Additionally, symptom-focused rumination and cognitive and behavioral avoidance mediated the relationship between self-compassion and depressive symptoms. These findings extend previous research on self-compassion, its relation to depression, as well as processes mediating this relationship, and highlight the importance of self-compassion in clinically depressed patients. Since depressed patients seem to have difficulties adopting a self-compassionate attitude, psychotherapists are well advised to explore and address how depressed patients treat themselves.

Species of Compassion: Aesthetics, Anaesthetics, and Pain in the Physiological Laboratory

Directory of Open Access Journals (Sweden)

Rob Boddice

2012-12-01

Full Text Available This essay explores the interplay of different species of compassion with regard to physiological practices in the final decades of the nineteenth century. Drawing on the lexicon from which ideals of late-Victorian compassion were formed, it illustrates their contested nature, demonstrating how physiologists developed their own concepts of compassion based on the theories of Darwin and Spencer. Within this purview, the essay examines the historical specificity of antivivisectionist compassion as well as ways in which pain in the laboratory was conceptualized, experienced, and managed ethically. This article explores the interplay of different species of compassion with regard to physiological practices in the last quarter of the nineteenth century in Britain. The lexicographical web of late-Victorian compassion included ‘humanity’, ‘pity’, ‘commiseration’, ‘tenderness’ (or ‘tender sympathy’, and ‘sympathetic pain’, all of which projected contested ideals of both individual character and moral conduct. As well as showing the historical specificity of antivivisectionist compassion – a complex aesthetic of pain closely linked to disgust – the article will principally demonstrate that physiologists (and the community of evolutionary scientists in general were applying their own newly, but no less highly, developed form of compassion that emerged straight from the pages of Darwin and Spencer. There is a story here of pain awareness and pain imagination within physiology, specifically connected to feelings of ‘humanity’. In practice, this story centres on anaesthesia and its role in allowing physiologists to live up to an ideal of ‘imperturbability’. It includes an investigation into what physiologists thought about causing pain in animals, as well as analysis of what changed after the use of anaesthetics became widespread. The article inquires anew about the ways in which pain in the laboratory was conceptualized

In 2014, reverse total shoulder arthroplasty was approved in Japan. We were concerned that the base plate might be incompatible with Japanese who were generally smaller than Westerners. Therefore, we investigated the dimensions and morphology of the normal Japanese glenoid and compared with the normal French glenoid. One hundred Japanese shoulders without glenoid lesions (50 men and 50 women) were investigated and compared with 100 French shoulders (50 men and 50 women). Computed tomography was performed with 3-dimensional image reconstruction and images were analyzed using Glenosys software. Glenoid parameters (width, height, retroversion and inclination) were compared between Japanese and French subjects. In Japanese subjects, the mean glenoid width was 25.5mm, height was 33.3mm, retroversion was 2.3° and inclination was 11.6° superiorly. In French subjects, the mean glenoid width was 26.7mm, height was 35.4mm, retroversion was 6.0° and inclination was 10.4° superiorly. Glenoid width and height were significantly smaller in Japanese subjects than French subjects (P=0.001 and PFrench subjects (P<0.001). There was no significant difference of inclination. These findings will help surgeons to identify suitable patients for RSA and perform the procedure with appropriate preoperative planning. IV: retrospective or historical series.

Toward a comprehensive, theoretical model of compassion fatigue: An integrative literature review.

Science.gov (United States)

Coetzee, Siedine K; Laschinger, Heather K S

2018-03-01

This study was an integrative literature review in relation to compassion fatigue models, appraising these models, and developing a comprehensive theoretical model of compassion fatigue. A systematic search on PubMed, EbscoHost (Academic Search Premier, E-Journals, Medline, PsycINFO, Health Source Nursing/Academic Edition, CINAHL, MasterFILE Premier and Health Source Consumer Edition), gray literature, and manual searches of included reference lists was conducted in 2016. The studies (n = 11) were analyzed, and the strengths and limitations of the compassion fatigue models identified. We further built on these models through the application of the conservation of resources theory and the social neuroscience of empathy. The compassion fatigue model shows that it is not empathy that puts nurses at risk of developing compassion fatigue, but rather a lack of resources, inadequate positive feedback, and the nurse's response to personal distress. By acting on these three aspects, the risk of developing compassion fatigue can be addressed, which could improve the retention of a compassionate and committed nurse workforce. © 2017 John Wiley & Sons Australia, Ltd.

Spin Physics at COMPASS

International Nuclear Information System (INIS)

Schill, Christian

2012-01-01

The COMPASS experiment is a fixed target experiment at the CERN SPS using muon and hadron beams for the investigation of the spin structure of the nucleon and hadron spectroscopy. The main objective of the muon physics program is the study of the spin of the nucleon in terms of its constituents, quarks and gluons. COMPASS has accumulated data during 6 years scattering polarized muons off longitudinally or transversely polarized deuteron ( 6 LiD) or proton (NH 3 ) targets. Results for the gluon polarization are obtained from longitudinal double spin cross section asymmetries using two different channels, open charm production and high transverse momentum hadron pairs, both proceeding through the photon-gluon fusion process. Also, the longitudinal spin structure functions of the proton and the deuteron were measured in parallel as well as the helicity distributions for the three lightest quark flavours. With a transversely polarized target, results were obtained with proton and deuteron targets for the Collins and Sivers asymmetries for charged hadrons as well as for identified kaons and pions. The Collins asymmetry is sensitive to the transverse spin structure of the nucleon, while the Sivers asymmetry reflects correlations between the quark transverse momentum and the nucleon spin. Recently, a new proposal for the COMPASS II experiment was accepted by the CERN SPS which includes two new topics: Exclusive reactions like DVCS and DVMP using the muon beam and a hydrogen target to study generalized parton distributions and Drell-Yan measurements using a pion beam and a polarized NH 3 target to study transverse momentum dependent distributions.

UbiCompass: An IoT Interaction Concept

Directory of Open Access Journals (Sweden)

Günter Alce

2018-01-01

Full Text Available Lately, different wearable form factors have reached the consumer domain. Wearables enable at-a-glance access to information and can continually sense the surrounding environment. Internet of Things (IoT researchers have focused on the main enabling factors: the integration of several technologies and communication solutions. Less effort has been devoted to exploring how not-so-tech-savvy end users can discover and directly interact with the numerous connected things predicted by the IoT vision. This paper presents a novel IoT interaction concept called UbiCompass. A functional, smartwatch face prototype of the UbiCompass was developed and integrated with an existing smart home system, in which five different connected devices could be controlled using simple interaction. It was then compared to a traditional smartphone mobile application in a controlled experiment. The results show statistically significant differences in favor of the proposed concept. This highlights the potential the UbiCompass has as an IoT interaction concept.

Using Acceptance and Commitment Therapy to Increase Self-Compassion: A Randomized Controlled Trial.

Science.gov (United States)

Yadavaia, James E; Hayes, Steven C; Vilardaga, Roger

2014-10-01

Self-compassion has been shown to be related to several types of psychopathology, including traumatic stress, and has been shown to improve in response to various kinds of interventions. Current conceptualizations of self-compassion fit well with the psychological flexibility model, which underlies acceptance and commitment therapy (ACT). However, there has been no research on ACT interventions specifically aimed at self-compassion. This randomized trial therefore compared a 6-hour ACT-based workshop targeting self-compassion to a wait-list control. From pretreatment to 2-month follow-up, ACT was significantly superior to the control condition in self-compassion, general psychological distress, and anxiety. Process analyses revealed psychological flexibility to be a significant mediator of changes in self-compassion, general psychological distress, depression, anxiety, and stress. Exploratory moderation analyses revealed the intervention to be of more benefit in terms of depression, anxiety, and stress to those with greater trauma history.

Full Text Available The present study was conducted with the aim of understanding the psychosocial determinants of romantic inclination among youth in India. We involved 779 student participants from a large central university in south India in the age range of 18-24 years. The participants filled measures on romantic inclination, personality, attachment style, interpersonal attraction, and social influence on romantic relationship in addition to a questionnaire on demographic information and relationship history. Analysis of the data revealed that males showed higher level of romantic inclination than females. Those who had current/past involvement in a romantic relationship (Lovers showed higher levels of romantic inclination than those who had never involved in a romantic relationship (Non-lovers. Parents’ type of marriage (Love/arranged, close fiends’ involvement in romantic relationship too had a discriminatory role in romantic inclination. Romantic inclination was significantly related to personality factors, attachment style, media and peer influences on romantic relationships and interpersonal attraction. Extraversion, openness to experience, agreeableness, media influence, peer influence, secure attachment and physical attraction emerged as significant predictors of romantic inclination in a regression model. Structural Equations Modeling (SEM indicated that personality, attachment style and interpersonal attraction had a significant influence on romantic inclination mediated by both media and peer influences. Romantic inclination in turn significantly predicted romantic relationship status.

To describe the relationship between trainable qualities (mindfulness and self-compassion), with factors conceptually related to burnout and quality of care (sleep and resilience) in young health professionals and trainees. Cross-sectional survey. Large Midwestern academic health center. 213 clinicians and trainees. Sleep and resilience were assessed by using the 8-item PROMIS Sleep scale and the 6-item Brief Resilience Scale. Mindfulness and self-compassion were assessed using the 10-item Cognitive and Affective Mindfulness Scale, Revised and the 12-item Self-Compassion Scale. Health was assessed with Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health measures, and stress was assessed with the 10-item Perceived Stress Scale. After examination of descriptive statistics and Pearson correlations, multiple regression analyses were done to determine whether mindfulness and self-compassion were associated with better sleep and resilience. Respondents had an average age of 28 years; 73% were female. Professions included dieticians (11%), nurses (14%), physicians (38%), social workers (24%), and other (12%). Univariate analyses showed normative values for all variables. Sleep disturbances were significantly and most strongly correlated with perceived stress and poorer health, but also with less mindfulness and self-compassion. Resilience was strongly and significantly correlated with less stress and better mental health, more mindfulness, and more self-compassion. In these young health professionals and trainees, sleep and resilience are correlated with both mindfulness and self-compassion. Prospective studies are needed to determine whether training to increase mindfulness and self-compassion can improve clinicians' sleep and resilience or whether decreasing sleep disturbances and building resilience improves mindfulness and compassion.

Self-compassion moderates body comparison and appearance self-worth's inverse relationships with body appreciation.

Homan, Kristin J; Tylka, Tracy L

2015-09-01

Although research on positive body image has increased, little research has explored which variables protect body appreciation during body-related threats. Self-compassion may be one such variable. Individuals high in self-compassion are mindful, kind, and nurturing toward themselves during situations that threaten their adequacy, while recognizing that being imperfect is part of "being human." In this study, we investigated whether two body-related threats (i.e., body comparison and appearance contingent self-worth) were more weakly related to body appreciation when self-compassion was high among an online sample of 263 women (Mage=35.26, SD=12.42). Results indicated that self-compassion moderated the inverse relationships between body related threats and body appreciation. Specifically, when self-compassion was very high, body comparison and appearance contingent self-worth were unrelated to body appreciation. However, when self-compassion was low, these relationships were strong. Self-compassion, then, may help preserve women's body appreciation during body-related threats. Copyright © 2015 Elsevier Ltd.

2018-03-19

To analyze common values of bracket torque (Andrews, Roth, MBT, Ricketts) for their validity in achieving incisor inclinations that are considered normal by different cephalometric standards. Using the equations developed in part 1 (eU1 (BOP) = 90° - BT (U1) - TCA (U1) + α 1 - α 2 and eL1 (BOP) = 90° - BT (L1) - TCA (L1) + β 1 - β 2 ) (abbreviations see part 1) and the mean values (± SD) obtained as statistical measures in parts 1 and 2 of the study (α 1 and β 1 [1.7° ± 0.7°], α 2 [3.6° ± 0.3°], β 2 [3.2° ± 0.4°], TCA (U1) [24.6° ± 3.6°] and TCA (L1) [22.9° ± 4.3°]) expected (= theoretically anticipated) values were calculated for upper and lower incisors (U1 and L1) and compared to targeted (= cephalometric norm) values. For U1, there was no overlapping between the ranges of expected and targeted values, as the lowest targeted value of (58.3°; Ricketts) was higher than the highest expected value (56.5°; Andrews) relative to the bisected occlusal plane (BOP). Thus all of these torque systems will aim for flatter inclinations than prescribed by any of the norm values. Depending on target values, the various bracket systems fell short by 1.8-5.5° (Andrews), 6.8-10.5° (Roth), 11.8-15.5° (MBT), or 16.8-20.5° (Ricketts). For L1, there was good agreement of the MBT system with the Ricketts and Björk target values (Δ0.1° and Δ-0.8°, respectively), and both the Roth and Ricketts systems came close to the Bergen target value (both Δ2.3°). Depending on target values, the ranges of deviation for L1 were 6.3-13.2° for Andrews (Class II prescription), 2.3°-9.2° for Roth, -3.7 to -3.2° for MBT, and 2.3-9.2° for Ricketts. Common values of upper incisor bracket torque do not have acceptable validity in achieving normal incisor inclinations. A careful selection of lower bracket torque may provide satisfactory matching with some of the targeted norm values.

COMPASS RICH-1 is a large size gaseous Imaging Cherenkov Detector providing hadron identification in the range from 3 to 55 GeV/c, in the wide acceptance spectrometer of the COMPASS Experiment at CERN SPS. It uses a 3 m long C(4)F(10) radiator, a 21 m(2) large VUV mirror surface and two kinds of photon detectors: MAPMTs and MWPCs with CsI photocathodes, covering a total of 5.5 m(2). It is in operation since 2002 and its performance has increased in time thanks to progressive optimization and mostly to a major upgrade which was implemented in 2006. The main characteristics of COMPASS RICH-1 components are described and some specific aspects related to the radiator gas system, the mirror alignment, the MWPC electrical stability and the readout electronics are discussed. Some key features of the event reconstruction and the PID analysis are presented together with results from the COMPASS RICH-1 performance characterization study. (C) 2010 Elsevier B.V.

[Compassion as a mediator between stressful events and perceived stress in Greek students].

Science.gov (United States)

Tholouli, E; Maridaki-Kassotaki, A; Varvogli, L; Chrousos, G P

2016-01-01

Compassion is closely related with human's survival as a mammal and has been developed through evolution for pain reduction, for forming affiliative bonds and alliances with non kin in order to increase protection and cope with external threats. Compassion seems to influence people's ability to deal with life's adverse situations such as stress and it is linked with lower psychopathology and greater wellbeing. Compassion is closely related to empathy and altruism and it is defined as the recognition of the pain of the self or others' that is accompanied with the will to take action in order to relieve the person from pain. Its main features are kindness instead of self-judgment and indifference, the recognition of common humanity instead of the feeling of separation and mindfulness when facing adverse conditions instead of over-identification with one's pain or disengagement with the pain of others. According to the biopsychosocial approach, stress can be defined by three dimensions such as the cause or stressful factors that can be major life events or daily hassles, the perception of stress that is manifested through cognitive, emotional and behavioural reactions and the physiological response for achieving homeostasis. The purpose of the present study was to investigate the role of compassion for self and others in the occurrence of stressful events and levels of perceived stress in students. Participants were 280 undergraduate students from two Greek universities. Results indicated that students who had experienced a greater amount of stressful events during the past year reported having higher levels of perceived stress and that higher self-compassion was correlated with less perceived stress. Moreover, the adverse effect of stressful events on perceived stress was partially explained by the mediating role of self-compassion. Students who reported more stressful events showed higher compassion for others in opposition to compassion towards themselves but

2018-03-23

The objectives of this study were to determine whether glenoid inclination (1) could be measured accurately on magnetic resonance imaging (MRI) using computed tomography (CT) as a gold standard, (2) could be measured reliably on MRI, and (3) whether it differed between patients with rotator cuff tears and age-matched controls without evidence of rotator cuff tears or glenohumeral osteoarthritis. In this comparative retrospective radiographic study, we measured glenoid inclination on T1 coronal MRI corrected into the plane of the scapula. We determined accuracy by comparison with CT and inter-rater reliability. We compared glenoid inclination between patients with full-thickness rotator cuff tears and patients aged >50 years without evidence of a rotator cuff tear or glenohumeral arthritis. An a priori power analysis determined adequate power to detect a 2° difference in glenoid inclination. (1) In a validation cohort of 37 patients with MRI and CT, the intraclass correlation coefficient was 0.877, with a mean difference of 0° (95% confidence interval, -1° to 1°). (2) For MRI inclination, the inter-rater intraclass correlation coefficient was 0.911. (3) Superior glenoid inclination was 2° higher (range, 1°-4°, P rotator cuff tear group of 192 patients than in the control cohort of 107 patients. Glenoid inclination can be accurately and reliably measured on MRI. Although superior glenoid inclination is statistically greater in those with rotator cuff tears than in patients of similar age without rotator cuff tears or glenohumeral arthritis, the difference is likely below clinical significance.

Atkinson, David M; Rodman, John L; Thuras, Paul D; Shiroma, Paulo R; Lim, Kelvin O

2017-07-01

Burnout, a state of emotional exhaustion associated with negative personal and occupational outcomes, is prevalent among healthcare providers. A better understanding of the psychological factors that may be associated with resilience to burnout is essential to develop effective interventions. Self-compassion, which includes kindness toward oneself, recognition of suffering as part of shared human experience, mindfulness, and nonjudgment toward inadequacies and failures, may be one such factor. The purpose of this study was to examine the relationships between burnout, depression, and self-compassion in Veterans Affairs (VA) mental health staff. Cross-sectional study. VA medical center and affiliated community-based clinics. VA mental health staff. The 19-item Copenhagen Burnout Inventory, the 26-item Self-Compassion Scale, and the Patient Health Questionnaire 2-item depression screen. Demographic information included age, sex, years worked in current position, and number of staff supervised. One hundred and twenty-eight of a potential 379 individuals (33.8%) responded. Clerical support, nursing, social work, psychology, and psychiatry were the major professions represented. Self-compassion was inversely correlated with burnout (r = -0.41, p burnout remained significant even after accounting for depressive symptoms and demographic variables in a multiple linear regression model. Of all the variables examined, self-compassion was the strongest predictor of burnout. The results of this study support the hypothesis that self-compassion may be associated with resilience to burnout. Alternatively, decreased self-compassion may be a downstream effect of increased burnout. Prospective, longitudinal studies are needed to determine the directional relationship between these factors, and whether interventions that cultivate self-compassion may decrease burnout and/or protect against its negative personal and professional outcomes.

Slipping and rolling on an inclined plane

International Nuclear Information System (INIS)

Aghamohammadi, Cina; Aghamohammadi, Amir

2011-01-01

In the first part of the paper, using a direct calculation two-dimensional motion of a particle sliding on an inclined plane is investigated for general values of friction coefficient (μ). A parametric equation for the trajectory of the particle is also obtained. In the second part of the paper, the motion of a sphere on the inclined plane is studied. It is shown that the evolution equation for the contact point of a sliding sphere is similar to that of a point particle sliding on an inclined plane whose friction coefficient is 7/2 μ. If μ > 2/7 tan θ, for any arbitrary initial velocity and angular velocity, the sphere will roll on the inclined plane after some finite time. In other cases, it will slip on the inclined plane. In the case of rolling, the centre of the sphere moves on a parabola. Finally the velocity and angular velocity of the sphere are exactly computed.

1990-09-01

Discusses schemes for excavation of transport inclines in surface mines under conditions of weak, unstable rocks characterized by a high water content. The schemes are aimed at maximum reduction of excavation operations without infringing the safety of personnel. Use of walking draglines (the EhSh-20/90, EhSh-100/100 and EhSh-10/70) is evaluated. Optimum schemes for incline excavation and determining optimum slope inclination are described on the example of the Berezovsk brown coal surface mine in the USSR. Efficiency of optimum schemes is analyzed: range of excavation, safety degree, landslide hazards, water influx rate, accident rate, etc.

Novel operation mode for eliminating influence of inclination angle and friction in atomic force microscopy

International Nuclear Information System (INIS)

Wang, Fei; Wang, Yueyu; Zhou, Faquan; Zhao, Xuezeng

2010-01-01

The accuracy of topography imaging in contact force mode of atomic force microscopy (AFM) depends on the one-to-one corresponding relationship between the cantilever deflection and the tip-sample distance, whereas such a relationship cannot be always achieved in the presence of friction and incline angle of sample surface. Recently, we have developed a novel operation mode in which we keep the van der Waals force as constant instead of the applied normal force, to eliminate the effect of inclination angle and friction on topography imaging in the contact force mode. We have improved our AFM to enable the new operation mode for validation. Comparative experiments have been performed and the results have shown that the effect of friction and inclination angle on topography imaging in contact mode of AFM can be eliminated or at least decreased effectively by working in the new operation mode we present.

Jagiellonian University Polarized Drell-Yan measurements at COMPASS

CERN Document Server

Longo, R

2017-01-01

COMPASS is a fixed-target experiment operating on north area of SPS (M2 beamline) at CERN. An important part of the physics programme of the experiment is the exploration of the transverse spin structure of the nucleon via measurements of spin-(in)dependent azimuthal asymmetries in the semi-inclusive DIS and, recently, also in Drell-Yan processes. Drell-Yan measurements with a 190 GeV/c $\\pi^-$ beam impinging on a transversely polarized NH3 target started in the year 2015 (18 weeks data taking) and will be continued in 2018. The measurement of the Sivers and other azimuthal asymmetries in polarized SIDIS and Drell-Yan performed by COMPASS provides a unique possibility to test (pseudo-)universal features of transverse momentum-dependent parton distribution functions, predicted in QCD. In this review, results of the first ever measurements of the polarized Drell-Yan reaction performed by COMPASS are presented.

Polarized light modulates light-dependent magnetic compass orientation in birds

Science.gov (United States)

Muheim, Rachel; Sjöberg, Sissel; Pinzon-Rodriguez, Atticus

2016-01-01

Magnetoreception of the light-dependent magnetic compass in birds is suggested to be mediated by a radical-pair mechanism taking place in the avian retina. Biophysical models on magnetic field effects on radical pairs generally assume that the light activating the magnetoreceptor molecules is nondirectional and unpolarized, and that light absorption is isotropic. However, natural skylight enters the avian retina unidirectionally, through the cornea and the lens, and is often partially polarized. In addition, cryptochromes, the putative magnetoreceptor molecules, absorb light anisotropically, i.e., they preferentially absorb light of a specific direction and polarization, implying that the light-dependent magnetic compass is intrinsically polarization sensitive. To test putative interactions between the avian magnetic compass and polarized light, we developed a spatial orientation assay and trained zebra finches to magnetic and/or overhead polarized light cues in a four-arm “plus” maze. The birds did not use overhead polarized light near the zenith for sky compass orientation. Instead, overhead polarized light modulated light-dependent magnetic compass orientation, i.e., how the birds perceive the magnetic field. Birds were well oriented when tested with the polarized light axis aligned parallel to the magnetic field. When the polarized light axis was aligned perpendicular to the magnetic field, the birds became disoriented. These findings are the first behavioral evidence to our knowledge for a direct interaction between polarized light and the light-dependent magnetic compass in an animal. They reveal a fundamentally new property of the radical pair-based magnetoreceptor with key implications for how birds and other animals perceive the Earth’s magnetic field. PMID:26811473

This study aimed to identify relationships between compassion fatigue, burnout, and turnover intention in Korean hospital nurses. In total, 142 hospital nurses were surveyed as part of data collection. Data related to compassion fatigue, burnout, and turnover intention were collected using a questionnaire between May 2011 and September 2011. The data analysis was performed using PASW 19.0 program, which included one-way ANOVA, independent t-tests, Pearson's correlation coefficient, and hierarchical regression analysis. This study detected a positive correlation between compassion fatigue and burnout(r=.37, pturnover intention(r=.55, pturnover intention among Korean hospital nurses. The results indicate that it is necessary to reduce compassion fatigue, and turnover intention among Korean hospital nurses.

Thermal Stability of Magnetic Compass Sensor for High Accuracy Positioning Applications

Directory of Open Access Journals (Sweden)

Van-Tang PHAM

2015-12-01

Full Text Available Using magnetic compass sensors in angle measurements have a wide area of application such as positioning, robot, landslide, etc. However, one of the most phenomenal that affects to the accuracy of the magnetic compass sensor is the temperature. This paper presents two thermal stability schemes for improving performance of a magnetic compass sensor. The first scheme uses the feedforward structure to adjust the angle output of the compass sensor adapt to the variation of the temperature. The second scheme increases both the temperature working range and steady error performance of the sensor. In this scheme, we try to keep the temperature of the sensor is stable at the certain value (e.g. 25 oC by using a PID (proportional-integral-derivative controller and a heating/cooling generator. Many experiment scenarios have implemented to confirm the effectivity of these solutions.

2015-08-01

To estimate prevalence and explore potential causes and consequences of compassion satisfaction and compassion fatigue in UK emergency medicine consultants. A sequential mixed-methods design. Cross-sectional e-survey to all UK NHS emergency medicine consultants (n=1317) including Professional Quality of Life (ProQOL) (compassion satisfaction/fatigue), followed by interviews with consultants scoring above (n=6) and below (n=6) predefined ProQOL thresholds. 681 (52%) consultants responded. Most (98%) reported at least 'average' compassion satisfaction. Higher scores were associated with type of workplace (designated trauma centres faring better) and number of years worked as a consultant (gradually worsen over time, except 20 years onwards when it improves). Consultants with lower (worse) compassion satisfaction scores were more likely to report being irritable with patients or colleagues and reducing their standards of care (a third reported these behaviours at least monthly) and were more likely to intend to retire early (59% had such plans). Key features distinguishing 'satisfied' from 'fatigued' interviewed consultants included having strategies to deal with the high work intensities associated with their role and having positive views of the team within which they worked. The degree of variety in their roles and the ability to maintain empathy for their patients were also distinguishing features between these groups. Findings support an urgent review of workforce and resources in emergency medicine and suggest that a multifactorial approach to identification, prevention and treatment of occupational stress in the workforce is required that considers individual, job and organisational factors, particularly those that impact on perceived control and support at work.

2018-05-03

Indubitably, the challenges facing health-care social workers are becoming increasingly complex. Whilst these problematic professional circumstances compound the need for self-compassion among health-care social workers, few studies, if any, have explicitly examined self-compassion among this practitioner group. This cross-sectional study explored self-compassion among a sample of practitioners (N = 138) in one southeastern state. Results indicate that health-care social workers in this sample engage in self-compassion only moderately. Further, occupational and demographic/life characteristics (e.g., age, years practicing social work, average hours worked per week, health status, and relationship status, among others) are able to predict self-compassion scores. After a terse review of relevant literature, this paper will explicate findings from this study, discuss relevant points derived from said findings, and identify salient implication for health-care social work praxis.

Compassion Fatigue, Burnout, and Neonatal Abstinence Syndrome.

Science.gov (United States)

Sweigart, Erin

2017-01-01

NICU nurses have seen a dramatic increase in cases of neonatal abstinence syndrome (NAS). The care needs of infants with NAS are highly demanding and can lead to feelings of frustration and emotional exhaustion among NICU nurses. Although studies have examined the experiences of nurses caring for NAS patients, none have specifically addressed the risk for compassion fatigue and burnout. Nurses need practical strategies to reduce their risk for compassion fatigue and burnout when caring for these patients. Improved education and implementation of self-care measures can help nurses more effectively manage stress and positively impact care of these infants and their families.

This paper discusses meditation from the unique perspective of the nondual approach and explores the possible relevance of this approach to applications of love and compassion meditation in clinical settings. It contrasts the nondual approach with the better known gradual or goal-oriented, dualistic view of meditation. This paper also introduces one of the central ideas of the nondual approach-that love and compassion, like other positive qualities that are ordinarily considered as goals of meditation practice, can be found to be already present within oneself as innate dimensions of one's authentic being. © 2016 New York Academy of Sciences.

A fast photon-detection system for the detector RICH-1 of the COMPASS Experiment at CERN SPS is in operation since the 2006 run. It is based on the use of Multi-Anode Photomultipliers (MAPMTs) coupled to individual fused silica lens telescopes and fast read-out electronics. It has been designed taking into account the high photon flux in the central region of the detector and the high rate requirements of the COMPASS Experiment. We present the photon-detection design and construction, together with its characterization and measured performances based on the data collected in 2006.

Mission Critical: Nursing Leadership Support for Compassion to Sustain Staff Well-being.

Science.gov (United States)

Lown, Beth A

Compassion, the foundation of Nursing, is a source of both healing for those who suffer and of purpose and meaning for those who seek to heal others. Increasingly, however, the fast pace and volume of care and documentation requirements diminish time with patients and families and hinder the enactment of compassion. These issues and other aspects of the work environment decrease the satisfaction and well-being of professional caregivers and are contributing to a rising tide of burnout. Research suggests that employee engagement emerges from their satisfaction and well-being; however, it is difficult for an individual to engage when she or he feels depleted and unsupported. Nursing leaders and managers can play a significant role in support of compassionate practices for staff and improvement of the work environment and staff well-being. Compassion practices that recognize employees for the caring they show to patients and each other, and that provide the support needed to sustain their caring and compassion, are associated with significantly better patient ratings of their care experiences in hospitals and ambulatory settings. This article describes an example of a compassion practice, Schwartz Rounds®, a program that has been implemented internationally to enhance staff caring and compassion, teamwork, and psychological well-being. Schwartz Rounds have been included as a component of organizational initiatives to enhance staff well-being and patient experience, and as an individual program. Nurse leaders and managers who wish to engage their staff can do so by supporting their compassion and well-being.

Meson Spectroscopy at COMPASS

Grube, Boris

2015-01-01

The COmmon Muon and Proton Apparatus for Structure and Spectroscopy (COMPASS) is a multi-purpose fixed-target experiment at the CERN Super Proton Synchrotron (SPS) aimed at studying the structure and spectrum of hadrons. The two-stage spectrometer has a good acceptance for charged as well as neutral particles over a wide kinematic range and thus allows to access a wide range of reactions. Light mesons are studied with negative (mostly $\\pi^-$) and positive ($p$, $\\pi^+$) hadron beams with a momentum of 190 GeV/$c$. The spectrum of light mesons is investigated in various final states produced in diffractive dissociation reactions at squared four-momentum transfers to the target between 0.1 and 1.0 $(\\text{GeV}/c)^2$. The flagship channel is the $\\pi^-\\pi^+\\pi^-$ final state, for which COMPASS has recorded the currently largest data sample. These data not only allow to measure the properties of known resonances with high precision, but also to search for new states. Among these is a new resonance-like signal, t...

The goal of the COMPASS experiment at CERN is to study the structure and dynamics of hadrons. The two-stage spectrometer used by the experiment has large acceptance and covers a wide kinematic range for charged as well as neutral particles and can therefore measure a wide range of reactions. The spectroscopy of light mesons is performed with negative (mostly $\\pi^-$) and positive ($p$, $\\pi^+$) hadron beams with a momentum of 190 GeV/$c$. The light-meson spectrum is measured in different final states produced in diffractive dissociation reactions with squared four-momentum transfer $t$ to the target between 0.1 and 1.0 $(\\text{GeV}/c)^2$. The flagship channel is the $\\pi^-\\pi^-\\pi^+$ final state, for which COMPASS has recorded the currently world's largest data sample. These data not only allow to measure the properties of known resonances with high precision, but also to observe new states. Among these is a new axial-vector signal, the $a_1(1420)$, with unusual properties. Novel analysis techniques have been...

Ring formation on an inclined surface

Science.gov (United States)

Deegan, Robert; Du, Xiyu

2015-11-01

A drop dried on a solid surface will typically leave a narrow band of solute deposited along the contact line. We examined variations of this deposit due to the inclination of the substrate using numerical simulations of a two-dimensional drop, equivalent to a strip-like drop. An asymptotic analysis of the contact line region predicts that the upslope deposit will grow faster at early times, but the growth of this deposit ends sooner because the upper contact line depins first. From our simulations we find that the deposit can be larger at either the upper or lower contact line depending on the initial drop volume and substrate inclination. For larger drops and steeper inclinations, the early lead in deposited mass at the upper contact line is wiped out by the earlier depinning of the upper contact line and subsequent continued growth at the lower contact line. Conversely, for smaller drops and shallower inclinations, the early lead of the upper contact line is insurmountable despite its earlier termination in growth. Our results show that it is difficult to reconstruct a postiorithe inclination of the substrate based solely on the shape of the deposit. The authors thank the James S.

Marchand, Claude

2011-01-01

Up to now, COMPASS experiment essentially focussed, in it's program with muon beams, on studying aspects of the longitudinal momentum structure of the nucleon in the collinear approximation, like Δq(x) and ΔG/G(x). However, quarks can also have intrinsic transverse momentum in the nucleon, which give rise to a new class of Transverse Momentum Distribution (TMD) Parton Distribution Functions. As an example, Sievers function has been measured by both COMPASS and HERMES to be non zero on the proton, paving thus the way for more precise investigations. It is precisely the goal of the new COMPASS phase II proposal to investigate in more detail new transverse description of the nucleon structure. Deeply Virtual Compton Scattering (DVCS) will allow studies in the transverse space via Generalized Parton Distributions (GPDs). Transverse Mometum Dependent PDFs will essentially be studied in Drell-Yan (DY) reaction and SIDIS, and some universality arguments in QCD imply different signs for Sievers and Boer-Mulders functions in DY and SIDIS.

Using data from the Deep Ecliptic Survey (DES), we investigate the inclination distributions of objects in the Kuiper Belt. We present a derivation for observational bias removal and use this procedure to generate unbiased inclination distributions for Kuiper Belt objects (KBOs) of different DES dynamical classes, with respect to the Kuiper Belt plane. Consistent with previous results, we find that the inclination distribution for all DES KBOs is well fit by the sum of two Gaussians, or a Gaussian plus a generalized Lorentzian, multiplied by sin i. Approximately 80% of KBOs are in the high-inclination grouping. We find that Classical object inclinations are well fit by sin i multiplied by the sum of two Gaussians, with roughly even distribution between Gaussians of widths 2.0 +0.6 -0.5 0 and 8.1 +2.6 -2.1 0 . Objects in different resonances exhibit different inclination distributions. The inclinations of Scattered objects are best matched by sin i multiplied by a single Gaussian that is centered at 19.1 +3.9 -3.6 0 with a width of 6.9 +4.1 -2.7 0 . Centaur inclinations peak just below 20 0 , with one exceptionally high-inclination object near 80 0 . The currently observed inclination distribution of the Centaurs is not dissimilar to that of the Scattered Extended KBOs and Jupiter-family comets, but is significantly different from the Classical and Resonant KBOs. While the sample sizes of some dynamical classes are still small, these results should begin to serve as a critical diagnostic for models of solar system evolution.

Millions of individuals have access to raw genomic data using direct-to-consumer companies. The advent of large-scale sequencing projects, such as the Precision Medicine Initiative, will further increase the number of individuals with access to their own genomic information. However, querying genomic data requires a computer terminal and computational skill to analyze the data-an impediment for the general public. DNA Compass is a website designed to empower the public by enabling simple navigation of personal genomic data. Users can query the status of their genomic variants for over 1658 markers or tens of millions of documented single nucleotide polymorphisms (SNPs). DNA Compass presents the relevant genotypes of the user side-by-side with explanatory scientific resources. The genotype data never leaves the user's computer, a feature that provides improved security and performance. More than 12 000 unique users, mainly from the general genetic genealogy community, have already used DNA Compass, demonstrating its utility.

2017-09-01

To identify the mechanisms involved in the association between self-compassion and depression, we examined whether adaptive emotion regulation would mediate the relationship between self-compassion and depression in individuals with unipolar depression. Furthermore, we explored which specific emotion regulation skills would be most important in this relationship. Sixty-nine individuals with unipolar depression were assessed with the Self-Compassion Scale and the Emotion Regulation Skills Questionnaire at baseline and with the Beck Depression Inventory-II 1 week later. The results showed that successful application of emotion regulation skills mediates the association between self-compassion and depression. Among eight specific emotion regulation skills, only the ability to tolerate negative emotions was identified as a significant mediator in the self-compassion-depression relationship. These findings provide preliminary evidence that systematically fostering self-compassion might help depressed individuals cope with their symptoms by enhancing their abilities to tolerate undesired emotions. Systematically fostering self-compassion through specific compassion-focused interventions might facilitate a reduction in depressive symptoms by improving the person's emotion regulation abilities, especially by improving his or her ability to tolerate negative emotions. Hence, compassion-focused interventions might be particularly promising in depressed patients with a tendency to avoid negative emotions and deficits in tolerating them. © 2016 The British Psychological Society.

On the highly inclined vW leptokurtic asteroid families

Science.gov (United States)

Carruba, V.; Domingos, R. C.; Aljbaae, S.; Huaman, M.

2016-11-01

vW leptokurtic asteroid families are families for which the distribution of the normal component of the terminal ejection velocity field vW is characterized by a positive value of the γ2 Pearson kurtosis, I.e. they have a distribution with a more concentrated peak and larger tails than the Gaussian one. Currently, eight families are known to have γ2(vW) > 0.25. Among these, three are highly inclined asteroid families, the Hansa, Barcelona, and Gallia families. As observed for the case of the Astrid family, the leptokurtic inclination distribution seems to be caused by the interaction of these families with node secular resonances. In particular, the Hansa and Gallia family are crossed by the s - sV resonance with Vesta, that significantly alters the inclination of some of their members. In this work we use the time evolution of γ2(vW) for simulated families under the gravitational influence of all planets and the three most massive bodies in the main belt to assess the dynamical importance (or lack of) node secular resonances with Ceres, Vesta, and Pallas for the considered families, and to obtain independent constraints on the family ages. While secular resonances with massive bodies in the main belt do not significantly affect the dynamical evolution of the Barcelona family, they significantly increase the γ2(vW) values of the simulated Hansa and Gallia families. Current values of the γ2(vW) for the Gallia family are reached over the estimated family age only if secular resonances with Vesta are accounted for.

The COMPASS tokamak at IPP Prague is a small-size device with an ITER-relevant plasma geometry and operating in both the Ohmic as well as neutral beam assisted H-modes since 2012. A basic set of diagnostics installed at the beginning of the COMPASS operation has been gradually broadened in type of diagnostics, extended in number of detectors and collected channels and improved by an increased data acquisition speed. In recent years, a significant progress in diagnostic development has been motivated by the improved COMPASS plasma performance and broadening of its scientific programme (L-H transition and pedestal scaling studies, magnetic perturbations, runaway electron control and mitigation, plasma-surface interaction and corresponding heat fluxes, Alfvenic and edge localized mode observations, disruptions, etc.). In this contribution, we describe major upgrades of a broad spectrum of the COMPASS diagnostics and discuss their potential for physical studies. In particular, scrape-off layer plasma diagnostics will be represented by a new concept for microsecond electron temperature and heat flux measurements - we introduce a new set of divertor Langmuir and ball-pen probe arrays, newly constructed probe heads for reciprocating manipulators as well as several types of standalone probes. Among optical tools, an upgraded high-resolution edge Thomson scattering diagnostic for pedestal studies and a set of new visible light and infrared (plasma-surface interaction investigations) cameras will be described. Particle and beam diagnostics will be covered by a neutral particle analyzer, diagnostics on a lithium beam, Cherenkov detectors (for a direct detection of runaway electrons) and neutron detectors. We also present new modifications of the microwave reflectometer for fast edge density profile measurements.

Integration of polarization and chromatic cues in the insect sky compass.

Animals relying on a celestial compass for spatial orientation may use the position of the sun, the chromatic or intensity gradient of the sky, the polarization pattern of the sky, or a combination of these cues as compass signals. Behavioral experiments in bees and ants, indeed, showed that direct sunlight and sky polarization play a role in sky compass orientation, but the relative importance of these cues are species-specific. Intracellular recordings from polarization-sensitive interneurons in the desert locust and monarch butterfly suggest that inputs from different eye regions, including polarized-light input through the dorsal rim area of the eye and chromatic/intensity gradient input from the main eye, are combined at the level of the medulla to create a robust compass signal. Conflicting input from the polarization and chromatic/intensity channel, resulting from eccentric receptive fields, is eliminated at the level of the anterior optic tubercle and central complex through internal compensation for changing solar elevations, which requires input from a circadian clock. Across several species, the central complex likely serves as an internal sky compass, combining E-vector information with other celestial cues. Descending neurons, likewise, respond both to zenithal polarization and to unpolarized cues in an azimuth-dependent way.

The role of psychological factors in oncology nurses' burnout and compassion fatigue symptoms.

Duarte, Joana; Pinto-Gouveia, José

2017-06-01

This study explored the role of several psychological factors in professional quality of life in nurses. Specifically, we tried to clarify the relationships between several dimensions of empathy, self-compassion, and psychological inflexibility, and positive (compassion satisfaction) and negative (burnout and compassion fatigue) domains of professional quality of life. Using a cross-sectional design, a convenience sample of 221 oncology nurses recruited from several public hospitals filling out a battery of self-report measures. Results suggested that nurses that benefit more from their work of helping and assisting others (compassion satisfaction) seem to have more empathic feelings and sensibility towards others in distress and make an effort to see things from others' perspective. Also, they are less disturbed by negative feelings associated with seeing others' suffering and are more self-compassionate. Nurses more prone to experience the negative consequences associated with care-providing (burnout and compassion fatigue) are more self-judgmental and have more psychological inflexibility. In addition, they experience more personal feelings of distress when seeing others in suffering and less feelings of empathy and sensibility to others' suffering. Psychological factors explained 26% of compassion satisfaction, 29% of burnout and 18% of compassion fatigue. We discuss the results in terms of the importance of taking into account the role of these psychological factors in oncology nurses' professional quality of life, and of designing nursing education training and interventions aimed at targeting such factors.

Educational NASA Computational and Scientific Studies (enCOMPASS) is an educational project of NASA Goddard Space Flight Center aimed at bridging the gap between computational objectives and needs of NASA's scientific research, missions, and projects, and academia's latest advances in applied mathematics and computer science. enCOMPASS achieves this goal via bidirectional collaboration and communication between NASA and academia. Using developed NASA Computational Case Studies in university computer science/engineering and applied mathematics classes is a way of addressing NASA's goals of contributing to the Science, Technology, Education, and Math (STEM) National Objective. The enCOMPASS Web site at http://encompass.gsfc.nasa.gov provides additional information. There are currently nine enCOMPASS case studies developed in areas of earth sciences, planetary sciences, and astrophysics. Some of these case studies have been published in AIP and IEEE's Computing in Science and Engineering magazines. A few university professors have used enCOMPASS case studies in their computational classes and contributed their findings to NASA scientists. In these case studies, after introducing the science area, the specific problem, and related NASA missions, students are first asked to solve a known problem using NASA data and past approaches used and often published in a scientific/research paper. Then, after learning about the NASA application and related computational tools and approaches for solving the proposed problem, students are given a harder problem as a challenge for them to research and develop solutions for. This project provides a model for NASA scientists and engineers on one side, and university students, faculty, and researchers in computer science and applied mathematics on the other side, to learn from each other's areas of work, computational needs and solutions, and the latest advances in research and development. This innovation takes NASA science and

Veit, Benjamin [Institut fuer Kernphysik, Johannes Gutenberg-Universitaet Mainz (Germany); Collaboration: COMPASS collaboration

2016-07-01

In 2014/15 the COMPASS experiment measured double-muon-production in the reaction of negative pions of 190 GeV/c with a polarised ammonia target. This process is called Drell-Yan process. The final state consists of two muons and a hadronic state. The hadrons and remaining beam pions were removed by an absorber directly behind the target, the remaining muon pairs were detected in the double stage COMPASS spectrometer. For a symmetric acceptance for positive and negative muons, the single muon trigger system had to be modified. The necessary modifications on the single muon trigger and the performance of the new trigger are presented.

Protective Effect of Self-compassion to Emotional Response among Students with Chronic Academic Stress

Full Text Available The literature has shown that self-compassion is a protective factor of an individual’s emo-tional response to chronic stress. However, this stress-buffering effect has not been complete-ly analyzed in individuals who report significantly high academic stress. The present study explored the role of self-compassion in a group of undergraduate students who experience chronic academic stress. A total of 208 undergraduate students who were preparing for the Postgraduate Entrance Examination (PEE were recruited and completed the Self-Compassion Scale, Adolescent Self-Rating Life Event Check List, and Positive and Negative Affect Schedule. Differences analysis confirmed that the participants reported significantly higher academic stress than their peers who were not preparing for PEE. Self-compassion positively related to positive affect but negatively related to negative affect and learning stress. Further analysis showed that self-compassion negatively mediated the relationship be-tween chronic academic stress and negative affect. Findings imply that self-compassion-centered interventions can be developed in the educational context to assist students cope with chronic academic stress.

Visual Attention to Suffering After Compassion Training Is Associated With Decreased Amygdala Responses

Directory of Open Access Journals (Sweden)

Helen Y. Weng

2018-05-01

Full Text Available Compassion meditation training is hypothesized to increase the motivational salience of cues of suffering, while also enhancing equanimous attention and decreasing emotional reactivity to suffering. However, it is currently unknown how compassion meditation impacts visual attention to suffering, and how this impacts neural activation in regions associated with motivational salience as well as aversive responses, such as the amygdala. Healthy adults were randomized to 2 weeks of compassion or reappraisal training. We measured BOLD fMRI responses before and after training while participants actively engaged in their assigned training to images depicting human suffering or non-suffering. Eye-tracking data were recorded concurrently, and we computed looking time for socially and emotionally evocative areas of the images, and calculated visual preference for suffering vs. non-suffering. Increases in visual preference for suffering due to compassion training were associated with decreases in the amygdala, a brain region involved in negative valence, arousal, and physiological responses typical of fear and anxiety states. This pattern was specifically in the compassion group, and was not found in the reappraisal group. In addition, compassion training-related increases in visual preference for suffering were also associated with decreases in regions sensitive to valence and empathic distress, spanning the anterior insula and orbitofrontal cortex (while the reappraisal group showed the opposite effect. Examining visual attention alone demonstrated that engaging in compassion in general (across both time points resulted in visual attention preference for suffering compared to engaging in reappraisal. Collectively, these findings suggest that compassion meditation may cultivate visual preference for suffering while attenuating neural responses in regions typically associated with aversive processing of negative stimuli, which may cultivate a more

To examine how the concept of compassion is socially constructed within UK discourse, in response to recommendations that aspiring nurses gain care experience prior to entering nurse education. Following a report of significant failings in care, the UK government proposed prior care experience for aspiring nurses as a strategy to enhance compassion amongst the profession. Media reporting of this generated substantial online discussion, which formed the data for this research. There is a need to define how compassion is constructed through language as a limited understanding exists, of what compassion means in healthcare. This is important, for any meaningful evaluation of quality, compassionate practices. A corpus-informed discourse analysis. A 62626-word corpus of data was analysed using Laurence Anthony software 'AntCon', a free corpus analysis toolkit. Frequent words were retrieved and used as a focal point for further analysis. Concordance lines were computed and analysed in the context of which frequent word-types occurred. Patterns of language were revealed and interpreted through researcher immersion. Findings identified that compassion was frequently described in various ways as a natural characteristic attribute. A pattern of language also referred to compassion as something that was not able to be taught, but could be developed through the repetition of behaviours observed in practice learning. In the context of compassion, the word-type 'nurse' was used positively. This paper adds to important debates highlighting how compassion is constructed and defined in the context of nursing. Compassion is constructed as both an individual, personal trait and a professional behaviour to be learnt. Educational design could include effective interpersonal skills training, which may help enhance and develop compassion from within the nursing profession. Likewise, ways of thinking, behaving and communicating should also be addressed by established practitioners in

2018-02-01

The compass rose is one of the few "recurring patterns" found in financial markets. In this paper, the compass rose in Chinese A-share market is comprehensively investigated. It is newly discovered that among the 1331 A-shares, which had been listed for more than 15 years by the end of 2015, only about 20 show the compass rose. The outcome of the analysis shows that there exists a threshold of the ratio of the data points on main rays to all data points. Only when this ratio is above the threshold, the compass rose appears. The reasons why such a threshold exists, and its interrelationship with the data frequency and the tick/volatility ratio are analyzed.

The COMPASS Hadron Spectroscopy Programme

CERN Document Server

Austregesilo, A

2011-01-01

COMPASS is a fixed-target experiment at the CERN SPS for the investigation of the structure and the dynamics of hadrons. The experimental setup features a large acceptance and high momentum resolution spectrometer including particle identification and calorimetry and is therefore ideal to access a broad range of different final states. Following the promising observation of a spin-exotic resonance during an earlier pilot run, COMPASS focused on light-quark hadron spectroscopy during the years 2008 and 2009. A data set, world leading in terms of statistics and resolution, has been collected with a 190GeV/c hadron beam impinging on either liquid hydrogen or nuclear targets. Spin-exotic meson and glueball candidates formed in both diffractive dissociation and central production are presently studied. Since the beam composition includes protons, the excited baryon spectrum is also accessible. Furthermore, Primakoff reactions have the potential to determine radiative widths of the resonances and to probe chiral pe...

Magnetic Orientation in Birds and Other Animals

Science.gov (United States)

Wiltschko, Wolfgang

The use of the geomagnetic field for compass orientation is widespread among animals, with two types of magnetic compass mechanisms described: an shape inclination compass in birds, turtles and salamanders and a shape polarity compass in arthropods, fishes and mammals. Additionally, some vertebrates appear to derive positional information from the total intensity and/or inclination of the geomagnetic field. For magnetoreception by animals, two models are currently discussed, the shape Radical Pair model assuming light-dependent processes by specialized photopigments, and the shape Magnetite hypothesis proposing magnetoreception by crystals of magnetite, Fe304. Behavioral experiments with migratory birds, testing them under monochromatic lights and subjecting them to a brief, strong pulse that could reverse the magnetization of magnetite particles, produced evidence for both mechanisms. However, monochromatic lights affect old, experienced and young birds alike, whereas the pulse affects only experienced birds, leaving young, inexperienced birds unaffected. These observations suggest that a radical pair mechanism provides birds with directional information for their innate magnetic compass and a magnetite-based mechanism possibly mediates information about total intensity for indicating position.

Brilliance and flux reduction in imperfect inclined crystals

International Nuclear Information System (INIS)

Lee, W.K.; Blasdell, R.C.; Fernandez, P.B.; Macrander, A.T.; Mills, D.M.

1996-01-01

The inclined crystal geometry has been suggested as a method of reducing the surface absorbed power density of high-heat-load monochromators for third-generation synchrotron radiation sources. Computer simulations have shown that if the crystals are perfectly aligned and have no strains then the diffraction properties of a pair of inclined crystals are very similar to a pair of conventional flat crystals with only subtle effects differentiating the two configurations. However, if the crystals are strained, these subtle differences in the behavior of inclined crystals can result in large beam divergences causing brilliance and flux losses. This manuscript elaborates on these issues and estimates potential brilliance and flux losses from strained inclined crystals at the APS

A daily diary study of self-compassion, body image, and eating behavior in female college students.

Science.gov (United States)

Kelly, Allison C; Stephen, Elizabeth

2016-06-01

Although self-compassion is associated with healthier body image and eating behavior, these findings have generally emerged at the between-persons level only. The present study investigated the unique contributions of within-person variability in self-compassion, and between-persons differences in self-compassion, to body image and eating behavior. Over seven days, 92 female college students completed nightly measures of self-compassion, self-esteem, dietary restraint, intuitive eating, body appreciation, body satisfaction, and state body image. Multilevel modeling revealed that within-persons, day-to-day fluctuations in self-compassion contributed to day-to-day fluctuations in body image and eating. Between-persons, participants' average levels of self-compassion across days contributed to their average levels of body image and eating over the week. Results generally held when controlling for within- and between-persons self-esteem. Evidently, the eating and body image benefits of self-compassion may come not only from being a generally self-compassionate person, but also from treating oneself more self-compassionately than usual on a given day.

COMPASS is a fixed-target experiment at the CERN SPS, which investigates the structure and spectroscopy of hadrons. In 2004, a first run with a 190 GeV/c {pi}{sup -} beam took place, using nuclear targets. Diffractive reactions in COMPASS provide clean access to meson resonances with masses below 2.5 GeV/c{sup 2}, where candidates for spin-exotic states (e. g. 1{sup -+}) have been reported in the past. Within a few days of data taking, a competitive number of events on lead with {pi}{sup -}{pi}{sup -}{pi}{sup +} final states were recorded. In this talk we report on the results of a first partial wave analysis of this data set.

In the COMPASS experiment, under construction at CERN, about 23000 channels of MWPCs will be used. The very high rate of the muon and hadron beams, and the consequently high trigger rate, require front- end electronics with innovative conceptual design. A new MWPC front- end electronics that fulfills the main COMPASS requirement to have a fast DAQ with a minimum dead-time has been designed. The general concept of the front-end cards is described; the comparative tests of two front-end chips, and different fast gas mixtures, are also shown. The commissioning of the experiment will start in the summer 2000, and production running, using the muon beam, is foreseen for the year 2001. (8 refs).

The compass rose pattern in electricity prices.

The "compass rose pattern" is known to appear in the phase portraits, or scatter diagrams, of the high-frequency returns of financial series. We first show that this pattern is also present in the returns of spot electricity prices. Early researchers investigating these phenomena hoped that these patterns signaled the presence of rich dynamics, possibly chaotic or fractal in nature. Although there is a definite autoregressive and conditional heteroscedasticity structure in electricity returns, we find that after simple filtering no pattern remains. While the series is non-normal in terms of their distribution and statistical tests fail to identify significant chaos, there is evidence of fractal structures in periodic price returns when measured over the trading day. The phase diagram of the filtered returns provides a useful visual check on independence, a property necessary for pricing and trading derivatives and portfolio construction, as well as providing useful insights into the market dynamics.

Self-compassion may protect individuals experiencing poor body image and associated maladaptive outcomes. The purpose of the study was to examine within-person associations (whilst controlling for between-person differences) between appearance-related self-compassion, appearance-related threats (operationalised as upward appearance comparisons), and body image-related variables, namely, social physique anxiety, drive for thinness, and body dissatisfaction. A diary methodology was used whereby young women (n = 126; M age = 21.26) responded to brief online surveys three times per day (11am, 3pm, and 7pm) every second day for one week (i.e. a total of 12 measurement points). Results of mixed linear modeling revealed that both state appearance-related upward comparisons and self-compassion independently predicted all three outcomes in a positive and negative fashion, respectively. No significant interaction effects between state appearance-related upward comparisons and self-compassion were found. The results suggested that appearance-based self-compassion was important, not just when there was a potential threat to body image via upward appearance comparisons. The findings highlight the importance of fostering self-compassion on a daily level. © 2017 The International Association of Applied Psychology.

The importance of compassion is widely recognized and it is receiving increasing research attention. Yet, there is lack of consensus on definition and a paucity of psychometrically robust measures of this construct. Without an agreed definition and adequate measures, we cannot study compassion, measure compassion or evaluate whether interventions designed to enhance compassion are effective. In response, this paper proposes a definition of compassion and offers a systematic review of self- and observer-rated measures. Following consolidation of existing definitions, we propose that compassion consists of five elements: recognizing suffering, understanding the universality of human suffering, feeling for the person suffering, tolerating uncomfortable feelings, and motivation to act/acting to alleviate suffering. Three databases were searched (Web of Science, PsycInfo, and Medline) and nine measures included and rated for quality. Quality ratings ranged from 2 to 7 out of 14 with low ratings due to poor internal consistency for subscales, insufficient evidence for factor structure and/or failure to examine floor/ceiling effects, test-retest reliability, and discriminant validity. We call our five-element definition, and if supported, the development of a measure of compassion based on this operational definition, and which demonstrates adequate psychometric properties.

Acute health care environments can be stressful settings with clinicians experiencing deleterious effects of burnout and compassion fatigue affecting their mental health. Subsequently, the quality of patient care and outcomes may be threatened if clinicians experience burnout or compassion fatigue. Therefore, the aim of this descriptive, cross-sectional study was to evaluate the prevalence of burnout and compassion fatigue among burn clinicians in Israel. Fifty-five clinicians from Burns, Plastics and Reconstruction Surgery and Intensive Care completed four validated surveys to assess burnout (Maslach Burnout Inventory), depression (PRIME-MD), health-related quality of life (SF-8), and compassion fatigue (Professional Quality of Life version 5). Burn clinicians were compared with Plastics and Reconstruction Surgery and Intensive Care clinicians. This study identified a high prevalence of burnout (38.2%) among Intensive Care, Plastics and Reconstruction and Burns clinicians, with Burns clinicians having a greatly increased prevalence of burnout compared to Intensive Care clinicians (OR =24.3, P =0.017). Additional factors contributing to compassion fatigue were those without children ( P =0.016), divorced ( P =0.035), of a younger age ( P =0.019), and a registered nurse ( P =0.05). Burnout increased clinicians' risk of adverse professional and personal outcomes and correlated with less free time ( P work-home disputes ( P =0.05), increased depression ( P =0.001) and decreased career satisfaction ( P =0.01). Burnout was also associated with higher physical (mean difference =3.8, P <0.001) and lower mental (mean difference =-3.5, P <0.001) Quality of Life scores. Caring for burn survivors can lead to burnout, compassion fatigue, and vicarious trauma. Identifying strategies to abate these issues is essential to ensure improved clinicial environments and patient outcomes.

Compassion Is a Necessity and an Individual and Collective Responsibility; Comment on “Why and How Is Compassion Necessary to Provide Good Quality Healthcare?”

Directory of Open Access Journals (Sweden)

Beth A. Lown

2015-09-01

Full Text Available Compassion is a complex process that is innate, determined in part by individual traits, and modulated by a myriad of conscious and unconscious factors, immediate context, social structures and expectations, and organizational “culture.” Compassion is an ethical foundation of healthcare and a widely shared value; it is not an optional luxury in the healing process. While the interrelations between individual motivation and social structure are complex, we can choose to act individually and collectively to remove barriers to the innate compassion that most healthcare professionals bring to their work. Doing so will reduce professional burnout, improve the well-being of the healthcare workforce, and facilitate our efforts to achieve the triple aim of improving patients’ experiences of care and health while lowering costs.

Movements of a Sphere Moving Over Smooth and Rough Inclines

The steady movements of a sphere over a rough incline in air, and over smooth and rough inclines in a liquid were studied theoretically and experimentally. The principle of energy conservation was used to analyze the translation velocities, rolling resistances, and drag coefficients of a sphere moving over the inclines. The rolling resistance to the movement of a sphere from the rough incline was presumed to be caused by collisions and frictional slidings. A varnished wooden board was placed on the bottom of an experimental tilting flume to form a smooth incline and a layer of spheres identical to the sphere moving over them was placed on the smooth wooden board to form a rough incline. Spheres used in the experiments were glass spheres, steel spheres, and golf balls. Experiments show that a sphere moving over a rough incline with negligible fluid drag in air can reach a constant translation velocity. This constant velocity was found to be proportional to the bed inclination (between 11 ^circ and 21^circ) and the square root of the sphere's diameter, but seemingly independent of the sphere's specific gravity. Two empirical coefficients in the theoretical expression of the sphere's translation velocity were determined by experiments. The collision and friction parts of the shear stress exerted on the interface between the moving sphere and rough incline were determined. The ratio of collision to friction parts appears to increase with increase in the bed inclination. These two parts seem to be of the same order of magnitude. The rolling resistances and the relations between the drag coefficient and Reynolds number for a sphere moving over smooth and rough inclines in a liquid, such as water or salad oil, were determined by a regression analysis based on experimental data. It was found that the drag coefficient for a sphere over the rough incline is larger than that for a sphere over the smooth incline, and both of which are much larger than that for a sphere in free

Developing compassion towards oneself has been linked to improvement in many areas of psychological well-being, including psychosis. Furthermore, developing a non-judgemental, accepting way of relating to voices is associated with lower levels of distress for people who hear voices. These factors have also been associated with secure attachment. This study explores associations between the constructs of mindfulness of voices, self-compassion, and distress from hearing voices and how secure attachment style related to each of these variables. Cross-sectional online. One hundred and twenty-eight people (73% female; M age  = 37.5; 87.5% Caucasian) who currently hear voices completed the Self-Compassion Scale, Southampton Mindfulness of Voices Questionnaire, Relationships Questionnaire, and Hamilton Programme for Schizophrenia Voices Questionnaire. Results showed that mindfulness of voices mediated the relationship between self-compassion and severity of voices, and self-compassion mediated the relationship between mindfulness of voices and severity of voices. Self-compassion and mindfulness of voices were significantly positively correlated with each other and negatively correlated with distress and severity of voices. Mindful relation to voices and self-compassion are associated with reduced distress and severity of voices, which supports the proposed potential benefits of mindful relating to voices and self-compassion as therapeutic skills for people experiencing distress by voice hearing. Greater self-compassion and mindfulness of voices were significantly associated with less distress from voices. These findings support theory underlining compassionate mind training. Mindfulness of voices mediated the relationship between self-compassion and distress from voices, indicating a synergistic relationship between the constructs. Although the current findings do not give a direction of causation, consideration is given to the potential impact of mindful and

Compassion is considered an essential element in quality patient care. One of the conceptual challenges in healthcare literature is that compassion is often confused with sympathy and empathy. Studies comparing and contrasting patients' perspectives of sympathy, empathy, and compassion are largely absent. The aim of this study was to investigate advanced cancer patients' understandings, experiences, and preferences of "sympathy," "empathy," and "compassion" in order to develop conceptual clarity for future research and to inform clinical practice. Data were collected via semi-structured interviews and then independently analyzed by the research team using the three stages and principles of Straussian grounded theory. Data were collected from 53 advanced cancer inpatients in a large urban hospital. Constructs of sympathy, empathy, and compassion contain distinct themes and sub-themes. Sympathy was described as an unwanted, pity-based response to a distressing situation, characterized by a lack of understanding and self-preservation of the observer. Empathy was experienced as an affective response that acknowledges and attempts to understand individual's suffering through emotional resonance. Compassion enhanced the key facets of empathy while adding distinct features of being motivated by love, the altruistic role of the responder, action, and small, supererogatory acts of kindness. Patients reported that unlike sympathy, empathy and compassion were beneficial, with compassion being the most preferred and impactful. Although sympathy, empathy, and compassion are used interchangeably and frequently conflated in healthcare literature, patients distinguish and experience them uniquely. Understanding patients' perspectives is important and can guide practice, policy reform, and future research.

Impinging Water Droplets on Inclined Glass Surfaces

Multiphase computational models and tests of falling water droplets on inclined glass surfaces were developed to investigate the physics of impingement and potential of these droplets to self-clean glass surfaces for photovoltaic modules and heliostats. A multiphase volume-of-fluid model was developed in ANSYS Fluent to simulate the impinging droplets. The simulations considered different droplet sizes (1 mm and 3 mm), tilt angles (0°, 10°, and 45°), droplet velocities (1 m/s and 3 m/s), and wetting characteristics (wetting=47° contact angle and non-wetting = 93° contact angle). Results showed that the spread factor (maximum droplet diameter during impact divided by the initial droplet diameter) decreased with increasing inclination angle due to the reduced normal force on the surface. The hydrophilic surface yielded greater spread factors than the hydrophobic surface in all cases. With regard to impact forces, the greater surface tilt angles yielded lower normal forces, but higher shear forces. Experiments showed that the experimentally observed spread factor (maximum droplet diameter during impact divided by the initial droplet diameter) was significantly larger than the simulated spread factor. Observed spread factors were on the order of 5 - 6 for droplet velocities of ~3 m/s, whereas the simulated spread factors were on the order of 2. Droplets were observed to be mobile following impact only for the cases with 45° tilt angle, which matched the simulations. An interesting phenomenon that was observed was that shortly after being released from the nozzle, the water droplet oscillated (like a trampoline) due to the "snapback" caused by the surface tension of the water droplet being released from the nozzle. This oscillation impacted the velocity immediately after the release. Future work should evaluate the impact of parameters such as tilt angle and surface wettability on the impact of particle/soiling uptake and removal to investigate ways that

The EMC effect or a modification of parton distributions in bound nucleons as compared to free ones, has been extensively studied during the last 30 years but its full understanding is still lacking. The COMPASS experiment at CERN will provide new results on the EMC effect, originating from the Drell-Yan process and studied in the 190 GeV=c π- beam scattering on the ammonia and tungsten targets. The present understanding of the EMC effect and experimental possibilities of COMPASS in this context are discussed.

1987-11-01

The records of 11 patients referred for treatment of TMJ disorders were used to compare condylar inclination found by drawing a tangent and by using a mathematic technique. Needle point tracing angles were also measured for the same patients and were compared with the condylar inclination. It can be concluded that (1) the mathematic technique outlined records a more accurate condylar angulation, and (2) there is a great variation in condylar inclination values between patients and between left and right sides of the same patient, and (3) there is no direct relationship between condylar inclination and the needle point tracing angle.

Research has identified the experience of shame as a relevant predictor of depressive symptoms. Building upon resilience theory, this is the first study to investigate if self-compassion and/or contingent self-worth (i.e., family support and God's love) mediate the link between shame and depressive symptoms. Participants were 109 African Americans, within the age range of 18 and 64, who sought service following a suicide attempt from a public hospital that serves mostly low-income patients. Findings suggest that shame was related to depressive symptoms through self-compassion but not through contingent self-worth, underscoring the significant role that self-compassion plays in ameliorating the aggravating effect of shame on depressive symptoms. Results highlight the value of incorporating self-compassion training into interventions for suicidal African Americans in an effort to reduce the impact of shame on their depressive symptoms and ultimately their suicidal behavior and as a result enhance their capacity for resilience.

Transverse spin azimuthal asymmetries at COMPASS: SIDIS Multi-D analysis & Drell-Yan

CERN Document Server

Parsamyan, Bakur

2015-01-01

COMPASS is a high-energy physics experiment operating on the M2 beam line at the SPS at CERN. Using high energy muon and hadron beams the experiment covers broad range of physics aspects in the field of the hadron structure and spectroscopy. One of the important objectives of the COMPASS experiment is the exploration of transverse spin structure of the nucleon via study of spin (in)dependent azimuthal asymmetries with semi-inclusive deep inelastic scattering (SIDIS) processes and starting from 2014 also with Drell-Yan (DY) reactions. Experimental results obtained by COMPASS for azimuthal effects in SIDIS play an important role in the general understanding of the three-dimensional nature of the nucleon. Giving access to the entire "twist-2" set of transverse momentum dependent (TMD) parton distribution functions (PDFs) and fragmentation functions (FFs) COMPASS data trigger constant theoretical interest and are being widely used in phenomenological analyses and global data fits. In particular, recent unique x-$...

This study examined neural activation during the experience of compassion, an emotion that orients people toward vulnerable others and prompts caregiving, and pride, a self-focused emotion that signals individual strength and heightened status. Functional magnetic resonance images (fMRI) were acquired as participants viewed 55 s continuous sequences of slides to induce either compassion or pride, presented in alternation with sequences of neutral slides. Emotion self-report data were collected after each slide condition within the fMRI scanner. Compassion induction was associated with activation in the midbrain periaqueductal gray (PAG), a region that is activated during pain and the perception of others' pain, and that has been implicated in parental nurturance behaviors. Pride induction engaged the posterior medial cortex, a region that has been associated with self-referent processing. Self-reports of compassion experience were correlated with increased activation in a region near the PAG, and in the right inferior frontal gyrus (IFG). Self-reports of pride experience, in contrast, were correlated with reduced activation in the IFG and the anterior insula. These results provide preliminary evidence towards understanding the neural correlates of important interpersonal dimensions of compassion and pride. Caring (compassion) and self-focus (pride) may represent core appraisals that differentiate the response profiles of many emotions.

Among the strengths of forensic psychiatry as a profession is its ability to support lively discussion of critical questions, such as how to characterize its own essence and whether it belongs to the practice of medicine. The American Academy of Psychiatry and the Law is fortunate that Michael Norko has taken the occasion of his presidential address to describe in depth the results of the advanced stage of his probing on a truly spiritual level the fundamental place of compassion in the practice of forensic psychiatry. In so doing, he casts inevitable light on the seamless connections binding forensic psychiatry and medicine, particularly the importance for both of practicing compassion in our search for truth. © 2018 American Academy of Psychiatry and the Law.

Possible relation between pulsar rotation and evolution of magnetic inclination

Science.gov (United States)

Tian, Jun

2018-05-01

The pulsar timing is observed to be different from predicted by a simple magnetic dipole radiation. We choose eight pulsars whose braking index was reliably determined. Assuming the smaller values of braking index are dominated by the secular evolution of the magnetic inclination, we calculate the increasing rate of the magnetic inclination for each pulsar. We find a possible relation between the rotation frequency of each pulsar and the inferred evolution of the magnetic inclination. Due to the model-dependent fit of the magnetic inclination and other effects, more observational indicators for the change rate of magnetic inclination are needed to test the relation.

Rethinking Compassion Fatigue Through the Lens of Professional Identity: The Case of Child-Protection Workers.

Science.gov (United States)

Geoffrion, Steve; Morselli, Carlo; Guay, Stéphane

2016-07-01

Compassion fatigue is currently the dominant model in work-related stress studies that explain the consequences of caring for others on child-protection workers. Based on a deterministic approach, this model excludes the role of cognition a priori and a posteriori in the understanding of the impact of caregiving or providing social support. By integrating the notion of professional identity, this article adds a subjective perspective to the compassion fatigue model allowing for the consideration of positive outcomes and takes into account the influence of stress caused by accountability. Mainly, it is argued that meanings derived from identity and given to situations may protect or accelerate the development of compassion fatigue or compassion satisfaction. To arrive at this proposition, the notions of compassion fatigue and identity theory are first reviewed. These concepts are then articulated around four work-related stressors specific to child-protection work. In light of this exercise, it is argued that professional identity serves as a subjective interpretative framework that guides the understanding of work-related situations. Therefore, compassion fatigue is not only a simple reaction to external stimuli. It is influenced by meanings given to the situation. Furthermore, professional identity modulates the impact of compassion fatigue on psychological well-being. Practice, policy, and research implications in light of these findings are also discussed. © The Author(s) 2015.

Light-Meson Spectroscopy at COMPASS

2017-01-01

The goal of the COMPASS experiment at CERN is to study the structure and spectroscopy of hadrons. The two-stage spectrometer has large acceptance and covers a wide kinematic range for charged as well as neutral particles allowing to access a wide range of reactions. Light mesons are studied with negative (mostly $\\pi^-$) and positive ($p$, $\\pi^+$) hadron beams with a momentum of $190\\,\\text{GeV}/c$. The light-meson spectrum is measured in different final states produced in diffractive dissociation reactions with squared four-momentum transfer $t$ to the target between $0.1$ and $1.0\\,(\\text{GeV}/c)^2$. The flagship channel is the $\\pi^-\\pi^+\\pi^-$ final state, for which COMPASS has recorded the currently world's largest data sample. These data not only allow us to measure the properties of known resonances with high precision, but also to search for new states. Among these is a new axial-vector signal, the $a_1(1420)$, with unusual properties. The findings are confirmed by the analysis of the $\\pi^-\\pi^0\\pi^...

Interactions between the visual and the magnetoreception system: different effects of bichromatic light regimes on the directional behavior of migratory birds.

2013-01-01

When magnetic compass orientation of migratory robins was tested, the birds proved well oriented under low intensity monochromatic light of shorter wavelengths up to 565 nm green; from 583 nm yellow onward, they were disoriented. In the present study, we tested robins under bichromatic lights composed (1) of 424 nm blue and 565 nm green and (2) of 565 nm green and 583 nm yellow at two intensities. Under dim blue-green light with a total quantal flux of ca. 8 × 10(15)quanta/sm(2), the birds were well oriented in their migratory direction by their inclination compass; under blue-green light of twice this intensity, their orientation became axial. In both cases, the magnetic directional information was mediated by the radical pair processes in the eye. When green and yellow light were combined, however, the nature of the behavior changed. Under green-yellow light of the higher intensity, the birds showed a 'fixed direction' response that was polar, no longer controlled by the normal inclination compass; under dim green-yellow light, the response became axial. Under these two light conditions, the respective directional information was mediated by the magnetite-based receptors in the skin of the upper beak. Apparently, yellow light leads to a change from one magnetoreception system to the other. How this change is effected is still unknown; it appears to reflect complex interactions between the visual and the two magnetoreception systems. Copyright © 2012 Elsevier Ltd. All rights reserved.

Embodying compassion: a virtual reality paradigm for overcoming excessive self-criticism.

Falconer, Caroline J; Slater, Mel; Rovira, Aitor; King, John A; Gilbert, Paul; Antley, Angus; Brewin, Chris R

2014-01-01

Virtual reality has been successfully used to study and treat psychological disorders such as phobias and posttraumatic stress disorder but has rarely been applied to clinically-relevant emotions other than fear and anxiety. Self-criticism is a ubiquitous feature of psychopathology and can be treated by increasing levels of self-compassion. We exploited the known effects of identification with a virtual body to arrange for healthy female volunteers high in self-criticism to experience self-compassion from an embodied first-person perspective within immersive virtual reality. Whereas observation and practice of compassionate responses reduced self-criticism, the additional experience of embodiment also increased self-compassion and feelings of being safe. The results suggest potential new uses for immersive virtual reality in a range of clinical conditions.

Deontological and utilitarian inclinations in moral decision making: a process dissociation approach.

Science.gov (United States)

Conway, Paul; Gawronski, Bertram

2013-02-01

Dual-process theories of moral judgment suggest that responses to moral dilemmas are guided by two moral principles: the principle of deontology states that the morality of an action depends on the intrinsic nature of the action (e.g., harming others is wrong regardless of its consequences); the principle of utilitarianism implies that the morality of an action is determined by its consequences (e.g., harming others is acceptable if it increases the well-being of a greater number of people). Despite the proposed independence of the moral inclinations reflecting these principles, previous work has relied on operationalizations in which stronger inclinations of one kind imply weaker inclinations of the other kind. The current research applied Jacoby's (1991) process dissociation procedure to independently quantify the strength of deontological and utilitarian inclinations within individuals. Study 1 confirmed the usefulness of process dissociation for capturing individual differences in deontological and utilitarian inclinations, revealing positive correlations of both inclinations to moral identity. Moreover, deontological inclinations were uniquely related to empathic concern, perspective-taking, and religiosity, whereas utilitarian inclinations were uniquely related to need for cognition. Study 2 demonstrated that cognitive load selectively reduced utilitarian inclinations, with deontological inclinations being unaffected. In Study 3, a manipulation designed to enhance empathy increased deontological inclinations, with utilitarian inclinations being unaffected. These findings provide evidence for the independent contributions of deontological and utilitarian inclinations to moral judgments, resolving many theoretical ambiguities implied by previous research.

2012-01-01

A major part of the future COMPASS program [1] is dedicated to the study of Deeply Virtual Compton Scattering (DVCS) and Meson Production (DVMP) to investigate nucleon structure through Generalised Parton Distributions (GPD). The high energy of the muon beam allows us to measure the xB-dependence of the t-slope of the pure DVCS cross section and to study nucleon tomography. In a first phase the use of positive and negative polarised muon beams and of an unpolarised proton target allow measurements of the Beam Charge and Spin Difference of the DVCS cross sections to access the Compton form factor related to the dominant GPD H. In a second phase we consider to use a transversely polarized proton target to constrain the GPD E.

VetCompass Australia is veterinary medical records-based research coordinated with the global VetCompass endeavor to maximize its quality and effectiveness for Australian companion animals (cats, dogs, and horses). Bringing together all seven Australian veterinary schools, it is the first nationwide surveillance system collating clinical records on companion-animal diseases and treatments.

Research on the well-being of lesbian, gay, and bisexual (LGB) people has predominately focused on Western (-ized) societies where individualism, and not collectivism, is emphasized. In the present study, we utilized a mediator model via Structural Equation Modeling (SEM) to examine the relationships between self-compassion (i.e., self-kindness, common humanity, and mindfulness), perceived social support (i.e., family, friends, and significant others), and subjective well-being (i.e., life satisfaction, positive affect, and negative affect) in a sample of LGB-identified individuals living in Turkey, a traditionally collectivistic culture (Hofstede, 2001). A sample of 291 LGB individuals (67 lesbian, 128 gay, and 96 bisexual) completed an online survey including the Positive and Negative Affect Schedule, Satisfaction with Life Scale, Multidimensional Scale of Perceived Social Support Scale, and Self-kindness, Common Humanity, and Mindfulness subscales of the Self-Compassion Scale. The results of SEM for the hypothesized mediator model revealed that self-compassion mediated the relationships between perceived social support from family and significant others and subjective well-being, explaining the 77% of the variance in subjective well-being. Implications for the literature base on LGB well-being are discussed, with a focus on the cross-cultural applications. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Natural Circulation Characteristics of a Symmetric Loop under Inclined Conditions

Full Text Available Natural circulation is an important process for primary loops of some marine integrated reactors. The reactor works under inclined conditions when severe accidents happen to the ship. In this paper, to investigate the characteristics of natural circulation, experiments were conducted in a symmetric loop under the inclined angle of 0~45°. A CFD model was also set up to predict the behaviors of the loop beyond the experimental scope. Total circulation flow rate decreases with the increase of inclined angle. Meanwhile one circulation is depressed while the other is enhanced, and accordingly the disparity between the branch circulations arises and increases with the increase of inclined angle. Circulation only takes place in one branch circuit at large inclined angle. Also based on the CFD model, the influences of flow resistance distribution and loop configuration on natural circulation are predicted. The numerical results show that to design the loop with the configuration of big altitude difference and small width, it is favorable to reduce the influence of inclination; however too small loop width will cause severe reduction of circulation ability at large angle inclination.

Full Text Available Keel bone damage (KBD is prevalent in hens raised for egg production, and ramps between different tiers in aviaries have potential to reduce the frequency of falls resulting in KBD. Effective use of ramps requires modulation of locomotion in anticipation of the incline. Inadequate adaptive locomotion may be one explanation why domestic layer hens (Gallus gallus domesticus exhibit high rates of KBD. To improve understanding of the capacity of hens to modulate their locomotion in anticipation of climbing, we measured the effects of incline angle upon the mechanics of the preparatory step before ascending a ramp. Because the energetic challenge of climbing increases with slope, we predicted that as angle of incline increased, birds during foot contact with the ground before starting to climb would increase their peak force and duration of contact and reduce variation in center of pressure (COP under their foot. We tested 20 female domestic chickens on ramp inclines at slopes of +0°, +40°, and +70° when birds were 17, 21, 26, 31, and 36 weeks of age. There were significantly higher vertical peak ground reaction forces in preparation at the steepest slope, and ground contact time increased significantly with each increase in ramp angle. Effects upon variation in COP were not apparent; likewise, effects of limb length, age, body mass were not significant. Our results reveal that domestic chickens are capable of modulating their locomotion in response to incline angle.

To use Compass as a model-based quality assurance (QA) tool for stereotactic body radiation therapy (SBRT) and stereotactic radiation therapy (SRT) volumetric modulated arc therapy (VMAT) treatment plans calculated with Eclipse treatment planning system (TPS). Twenty clinical stereotactic VMAT SBRT and SRT treatment plans were blindly selected for evaluation. Those plans included four different treatment sites: prostate, brain, lung and body. The plans were evaluated against dose-volume histogram (DVH) parameters and 2D and 3D gamma analysis. The dose calculated with Eclipse treatment planning system (TPS) was compared to Compass calculated dose (CCD) and Compass reconstructed dose (CRD). The maximum differences in mean dose of planning target volume (PTV) were 2.7 ± 1.0% between AAA and Acuros XB calculation algorithm TPS dose, -7.6 ± 3.5% between Eclipse TPS dose and CCD dose and -5.9 ± 3.7% between Eclipse TPS dose and CRD dose for both Eclipse calculation algorithms, respectively. 2D gamma analysis was not able to identify all the cases that 3D gamma analysis specified for further verification. Compass is suitable for QA of SBRT and SRT treatment plans. However, the QA process should include wide set of DVH-based dose parameters and 3D gamma analysis should be the preferred method when performing clinical patient QA. The results suggest that the Compass should not be used for smaller field sizes than 3 × 3 cm 2 or the beam model should be adjusted separately for both small (FS ≤ 3 cm) and large (FS > 3 cm) field sizes.

Sima Babaei

2017-01-01

Full Text Available Background: Compassion is an important part of nursing. It fosters better relationships between nurses and their patients. Moreover, it gives patients more confidence in the care they receive. Determining facilitators of compassion are essential to holistic care. The purpose of this study was to explore these facilitators. Materials and Methods: This ethnographic study was conducted in 2014–2015 with 20 nurses, 12 patients, and 4 family members in the medical and surgical wards. Data collection was done through observations and in-depth semi-structured interviews with purposive sampling. The study was carried out in 15 months. Data analysis was performed using constant comparison based on Strauss and Corbin. Results: Data analysis defined three main themes and eight subthemes as the fundamentals of compassion-based care. Nurses' personal factors with subcategories of personality, attitudes, and values and holistic view; and socio-cultural factors with subcategories of kindness role model, religious, and cultural values are needed to elicit compassionate behaviors. Initiator factors, with subcategories of patient suffering, patient communication demands, and patient emotional and psychological necessity are also needed to start compassionate behaviors. Conclusions: The findings of this study showed that nurses' communication with patients is nurse's duty in order to understand and respect the needs of patients. Attention should be paid to issues relating to compassion in nursing and practice educational programs. Indeed, creating a care environment with compassion, regardless of any shortcomings in the work condition, would help in the development of effective nursing.

Concept development of "compassion fatigue" in clinical nurses: Application of Schwartz-Barcott and Kim's hybrid model

Full Text Available Compassion fatigue is not a new concept in nursing; yet, it is not well known and there is no fixed clear definition of the term. The ambiguity surrounding how to define compassion fatigue has challenged its measurement and evaluation. Thus, any attempt to determine attributes of this underdeveloped concept and studying it in a new socio-cultural context requires concept development. The purpose of this study is to clarify the concept of compassion fatigue through concept development and to produce a vivid and tentative definition of this concept in clinical practice. Concept development was conducted using a three-step hybrid concept analysis including theoretical, fieldwork, and final analysis phases according to Schwartz-Barcott and Kim's method. We reviewed and analyzed 48 articles that met the inclusion criteria. Following, the first author conducted 13 interviews with clinical nurses followed by an inductive content analysis. Finally, a comprehensive definition of compassion fatigue in nurses was attained. Compassion fatigue in nurses can be explained as a cumulative and progressive process of absorption of the patient’s pain and suffering formed from the sympathetic and caring interactions with the patients and their families. The physical, emotional, intellectual, spiritual, social, and organizational consequences of compassion fatigue are so extensive that they threaten the existential integrity of the nurse. Context-based variables (culture, family, and community such as personality features like devotion behaviors and commitment towards the patient, exposure to multiple stressors, organizational challenges, and lack of self-care are factors associated with an increased risk of compassion fatigue. Concept development of compassion fatigue is the first step in the protection of nurses against the destructive consequences of compassion fatigue and to improve quality of care.

Highlights: • An upgrade of the COMPASS real-time system has been made to generally improve the plasma performance. • Stability of discharges in SNT configuration has been increased. • Plasma flat-top phase length has been extended. • Central solenoid protection has been developed. • Plasma position estimation has been improved. - Abstract: The COMPASS plasma control system is based on the MARTe real-time framework. Thanks to MARTe modularity and flexibility new algorithms have been developed for plasma diagnostic (plasma position calculation), control (shaping field control), and protection systems (central solenoid protection). Moreover, the MARTe framework itself was modified to broaden the communication capabilities via Aurora. This paper presents the recent upgrades and improvements made to the COMPASS real-time plasma control system, focusing on the issues related to precision of the real-time calculations, and discussing the improvements in terms of discharge parameters and stability. In particular, the new real-time system has given the possibility to analyze and to minimize the transport delays of each control loop.

'Have a nice day': consumerism, compassion and health care.

Science.gov (United States)

Sturgeon, David

Plans to implement a quality measurement framework that will rate nurses according to the level of care and compassion they demonstrate have been proposed and discussed in a number of Department of Health documents. From September 2010 degree-level nursing students in Wales will receive regular feedback on their communication skills and whether they are exhibiting sufficient levels of compassion. This article examines the reasons why there have been such moves by both politicians and health professionals to demonstrate, in quantifiable terms, that they are able to measure something that is frequently contextual and subject to individual interpretation. It explores how these moves have been influenced by the disclosure of unacceptable standards of care by the Patients Association report and the enquiry into Mid-Staffordshire NHS Foundation Trust. It also discusses how the adoption of targets to evaluate care and compassion seems to reflect a market-driven and bureaucratic approach to health care that has resulted in a system in which measurability and outcome are considered the most important indicator of quality.

Subsequently, the quality of patient care and outcomes may be threatened if clinicians experience burnout or compassion fatigue. Therefore, the aim of this descriptive, cross-sectional study was to evaluate the prevalence of burnout and compassion fatigue among burn clinicians in Israel. Fifty-five clinicians from Burns, Plastics and Reconstruction Surgery and Intensive Care completed four validated surveys to assess burnout (Maslach Burnout Inventory, depression (PRIME-MD, health-related quality of life (SF-8, and compassion fatigue (Professional Quality of Life version 5. Burn clinicians were compared with Plastics and Reconstruction Surgery and Intensive Care clinicians. This study identified a high prevalence of burnout (38.2% among Intensive Care, Plastics and Reconstruction and Burns clinicians, with Burns clinicians having a greatly increased prevalence of burnout compared to Intensive Care clinicians (OR =24.3, P=0.017. Additional factors contributing to compassion fatigue were those without children (P=0.016, divorced (P=0.035, of a younger age (P=0.019, and a registered nurse (P=0.05. Burnout increased clinicians’ risk of adverse professional and personal outcomes and correlated with less free time (P<0.001, increased risk of experiencing work-home disputes (P=0.05, increased depression (P=0

Self-compassion moderates the perfectionism and depression link in both adolescence and adulthood.

Psychological practitioners often seek to directly change the form or frequency of clients' maladaptive perfectionist thoughts, because such thoughts predict future depression. Indirect strategies, such as self-compassion interventions, that seek to change clients' relationships to difficult thoughts, rather than trying to change the thoughts directly could be just as effective. This study aimed to investigate whether self-compassion moderated, or weakened, the relationship between high perfectionism and high depression symptoms in both adolescence and adulthood. The present study utilised anonymous self-report questionnaires to assess maladaptive perfectionism, depression, and self-compassion across two samples covering much of the lifespan. Questionnaires were administered in a high school setting for the adolescent sample (Study 1, Mage = 14.1 years, n = 541), and advertised through university and widely online to attract a convenience sample of adults (Study 2, Mage = 25.22 years, n = 515). Moderation analyses revealed that self-compassion reduced the strength of relationship between maladaptive perfectionism and depression in our adolescent Study 1 (β = -.15, p < .001, R2 = .021.) and our adult study 2 (β = -.14, p < .001, R2 = .020). Cross-sectional self-reported data restricts the application of causal conclusions and also relies on accurate self-awareness and willingness to respond to questionnaire openly. The replication of this finding in two samples and across different age-appropriate measures suggests that self-compassion does moderate the link between perfectionism and depression. Self-compassion interventions may be a useful way to undermine the effects of maladaptive perfectionism, but future experimental or intervention research is needed to fully assess this important possibility.

Cognition and the compassion deficit: the social psychology of helping behaviour in nursing.

Science.gov (United States)

Paley, John

2014-10-01

This paper discusses compassion failure and compassion deficits in health care, using two major reports by Robert Francis in the UK as a point of reference. Francis enquired into events at the Mid Staffordshire Hospital between 2005 and 2009, events that unequivocally warrant the description 'appalling care'. These events prompted an intense national debate, along with proposals for significant changes in the regulation of nursing and nurse education. The circumstances are specific to the UK, but the issues are international. I suggest that social psychology provides numerous hints about the mechanisms that might have been involved at Mid Staffs and about the reasons why outsiders are blind to these mechanisms. However, there have been few references to social psychology in the post-Francis debate (the Francis Report itself makes no reference to it at all). It is an enormously valuable resource, and it has been overlooked. Drawing on the social psychology literature, I express scepticism about the idea that there was a compassion deficit among the Mid Staff nurses - the assumption that the appalling care had something to do with the character, attitudes, and values of nurses - and argue that the Francis Report's emphasis on a 'culture of compassion and caring in nurse recruitment, training and education' is misconceived. It was not a 'failure of compassion' that led to the events in Mid Staffs but an interlocking set of contextual factors that are known to affect social cognition. These factors cannot be corrected or compensated for by teaching ethics, empathy, and compassion to student nurses. © 2014 John Wiley & Sons Ltd.

A social neuroscience-informed model for teaching and practising compassion in health care.

Empathy and compassion are important catalysts for the healing process, but some research suggests their decline during training and practice. Compassion involves recognition, understanding, emotional resonance and empathic concern for another's concerns, distress, pain and suffering, coupled with their acknowledgement, and motivation and relational action to ameliorate these conditions. Neuroscientists have identified neural networks that generate shared representations of directly experienced and observed feelings, sensations and actions. When shared representations evoke empathic concern or compassion for another's painful situation, humans experience altruistic motivation to help. The resulting behaviours are associated with activation of areas in the brain associated with affiliation and reward. Activation of these neural networks is sensitive to multiple inter- and intrapersonal influences. These include the ability to focus one's attention, the ability to receive and accurately interpret input about distress, the perspective one adopts in order to understand another's experience, self-other boundary awareness, the degree to which one values another's welfare, the ability to recognise and regulate one's own emotions, the ability to attend to one's own wellbeing through self-care and self-compassion, effective communication skills, reflection and meta-cognition. Current research suggests that compassion can be modulated through education and training and is associated with positive emotions, a sense of affiliation, reward and prosocial behaviours. A compassion process model and framework with examples of educational goals, interventions and resources for curriculum development are described. However, education must be aligned with changes in clinical practice to sustain compassionate care. © 2016 John Wiley & Sons Ltd.

The Mediating Role of Self-Compassion in the Relationship Between Anxiety and Procrastination

2017-09-01

Full Text Available Background Procrastination is common among students. There are inconsistent evidence indicating the relationship between anxiety and procrastination. Similarly, underlying mechanisms of this relationship is not fully understood. One of these mechanisms may be self-compassion that may counteracts the negative effects of anxiety and procrastination. Hence, this research is aimed at investigating the mediating role of self-compassion in the relationship between anxiety and procrastination. Methods This cross-sectional study was conducted in Shahed University. Subjects were selected from different faculties through cluster sampling method. Since a minimum sample size of 200 is necessary for Structural Equation Models, we distributed 300 questionnaires, but 210 questionnaires were appropriate to analysis. Students were asked to answer to tests, including anxiety, self-compassion, and procrastination scale. Results Anxiety is correlated with procrastination and all subscales of self-compassion. Three components of self-compassion, including self-judgment (r = 0.305, P < 0.001, isolation (r = 0.225, P = 0.001, and over-identification (r = 0.288, P < 0.001 have significant correlation with procrastination. Results of calculation in AMOS showed self-judgment and over-identification explain the relationship between self-compassion and procrastination, and they are full mediators of the relationship between anxiety and procrastination (r = 0.236; P = 0.008; 95% CI (0.069, 0.453. Conclusions Results are consistent with the researches and theory. There are anxiety provoking factors among students correlated with the academic performance and getting accepted by peers, leading to self-judgment and over identification that are related to negative results such as procrastination.

Embodying compassion: a virtual reality paradigm for overcoming excessive self-criticism.

Directory of Open Access Journals (Sweden)

Caroline J Falconer

Full Text Available Virtual reality has been successfully used to study and treat psychological disorders such as phobias and posttraumatic stress disorder but has rarely been applied to clinically-relevant emotions other than fear and anxiety. Self-criticism is a ubiquitous feature of psychopathology and can be treated by increasing levels of self-compassion. We exploited the known effects of identification with a virtual body to arrange for healthy female volunteers high in self-criticism to experience self-compassion from an embodied first-person perspective within immersive virtual reality. Whereas observation and practice of compassionate responses reduced self-criticism, the additional experience of embodiment also increased self-compassion and feelings of being safe. The results suggest potential new uses for immersive virtual reality in a range of clinical conditions.

Full Text Available Nowadays, paralel to prolonging life time, illness experience can change life of everyone who takes care of the individual directly or indirectly. Prolonging of this time for patient, simultaneously causes prolonging of the time for the care and treatment providers and them to be with the patient more during illness and suffering process. Caring for chronically ill individuals by getting aware of that they won't be able to recover completely, causes them to experience various problems called compassion fatigue. Compasion fatigue is described as the natural feeling and behaviour arising from knowing the traumatizing events which a significant other has experienced; as the stress arising from helping or wanting to help a traumatized individual. The aim of this review is to describe compassion fatigue, explain the concepts with which it is related, and by this way to increase the awareness of professionals who work in helping professions.

Hadron muoproduction at the COMPASS experiment

CERN Document Server

Rajotte, J F

The COMPASS Collaboration has two main fields of interest: to improve our knowledge of the nucleon spin structure and to study hadrons through spectroscopy. These goals require a multipurpose universal spectrometer such as the COmmon Muon and Proton Apparatus for Structure and Spectroscopy, COMPASS. In its first years of data taking (2002-2007), the nucleon spin structure was studied with a polarized muon beam scattering off a polarized target. These studies resumed in 2010 and will continue until at least 2011. The years 2008 and 2009 were dedicated to hadron spectroscopy using hadron beams. In the case of the nucleon structure studies, it is crucial to detect with high precision the incoming beam muon (160 GeV), the scattered muon and the produced hadrons. The large amount of high quality data accumulated provides access to the unpolarized and polarized parton distributions of the nucleon and the hadronization process. Subtle differences (asymmetries) between polarized cross sections have been predicted for...

The purpose of this study was to evaluate and compare the anteroposterior (AP) position and inclination of the maxillary incisors in subjects with class I normal occlusion and a harmonious profile with patients with skeletal class III malocclusions, and to investigate the changes in maxillary incisor inclination and AP position after surgical-orthodontic treatment in class III patients. Sixty-five subjects (35 female and 30 male; mean age: 21.8 ± 3.89 years) with normal profiles and class I skeletal and dental patterns were selected as a control sample. Sixty-seven patients (38 female and 29 male; mean age: 21.3 ± 3.31 years) with skeletal and dental class III malocclusions who sought surgical-orthodontic treatment were used as the study sample. Subjects were asked to smile and profile photographs were taken with the head in a natural position and the maxillary central incisors and the forehead in full view; cephalograms were taken and superimposed on the profile pictures according to the outline of the forehead and nose. Forehead inclination, maxillary incisor facial inclination and the AP position of the maxillary central incisor relative to the forehead (FAFFA) were measured on the integrated images and statistical analyses were performed. In both groups, there were no significant male/female differences in either the maxillary central incisor inclination or AP position. Female subjects had a significantly steeper forehead inclination compared with males (P 0.05). In the control group, 84.6% had the facial axial point (FA) of their maxillary central incisors positioned between lines through the forehead facial axis (FFA) point and the glabella. In the study group, however, 79.1% had the maxillary central incisors positioned posterior to the line through the FFA point and the difference with the control group was statistically significant (P 0.05). With the integrated radiograph-photograph method, the lateral cephalogram was reoriented, which makes it possible

The study objective was to examine the effects of two conceptually related constructs, self-compassion and dispositional mindfulness, on executive function (EF) proficiency among early adolescents. Executive function refers to a set of psychological processes governing emotional regulation, organization, and planning. While the benefits of positive psychology appear evident for mental health and wellness, little is known about the etiological relationship between dispositional mindfulness and self-compassion in their associations with EF. Two hundred and ten early adolescents attending middle school (age M=12.5 years; SD=0.5; 21% Hispanic, 18% Mixed/bi-racial, 47% White, and 9% Other/Missing; 37.1% on free lunch program) self-reported levels of dispositional mindfulness (Mindful Attention Awareness Scale; MAAS), self-compassion (Self-Compassion Scale; SCS; self-judgment and self-kindness domains), and EF proficiency (Behavior Rating Inventory of Executive Function; BRIEF-SR). A sequential linear regression stepwise approach was taken entering the independent variables as separate models in the following order: self-kindness, self-judgement, and dispositional mindfulness. All models controlled for participant age and sex. SCS self-kindness was not associated with EF proficiency, but SCS self-judgment (reverse-coded) contributed to the variance in EF (β=0.40, p mindfulness appears to outweigh that of specific self-compassion domains, when independent of contemplative training.

Compassion is a core value embedded in the concept of quality in healthcare. The need for compassion toward healthcare staff in the workplace, for their own health and well-being and also to enable staff to deliver compassionate care for patients, is increasingly understood. However, we do not currently know how healthcare staff understand and characterize compassion toward themselves as opposed to patients. The aim of this study was to use social media for the generation and collection of primary data to gain understanding of the concept of workplace compassion. Tweets that contained the hashtag #ShowsWorkplaceCompassion were collected from Twitter and analyzed. The study took place between April 21 and May 21, 2016. Participants were self-selecting users of the social media service Twitter. The study was promoted by a number of routes: the National Health Service (NHS) England website, the personal Twitter accounts of the research team, internal NHS England communications, and via social media sharing. Participants were asked to contribute their views about what activities, actions, policies, philosophies or approaches demonstrate workplace compassion in healthcare using the hashtag #ShowsWorkplaceCompassion. All tweets including the research hashtag #ShowsWorkplaceCompassion were extracted from Twitter and studied using content analysis. Data concerning the frequency, nature, origin, and location of Web-based engagement with the research campaign were collected using Bitly (Bitly, Inc, USA) and Symplur (Symplur LLC, USA) software. A total of 260 tweets were analyzed. Of the 251 statements within the tweets that were coded, 37.8% (95/251) of the statements concerned Leadership and Management aspects of workplace compassion, 29.5% (74/251) were grouped under the theme related to Values and Culture, 17.5% (44/251) of the statements related to Personalized Policies and Procedures that support workplace compassion, and 15.2% (38/251) of the statements concerned

A previous study provided information regarding the quality of in-clinic veterinary biochemistry testing. However, no similar studies for in-clinic veterinary hematology testing have been conducted. The objective of this study was to assess the quality of hematology testing in veterinary in-clinic laboratories using results obtained from testing 3 levels of canine EDTA blood samples. Clinicians prepared blood samples to achieve measurand concentrations within, below, and above their RIs and evaluated the samples in triplicate using their in-clinic analyzers. Quality was assessed by comparison of calculated total error with quality requirements, determination of sigma metrics, use of a quality goal index, and agreement between in-clinic and reference laboratory instruments. Suitability for statistical quality control was determined using adaptations from the computerized program, EZRules3. Evaluation of 10 veterinary in-clinic hematology analyzers showed that these instruments often fail to meet quality requirements. At least 60% of analyzers reasonably determined RBC, WBC, HCT, and HGB, when assessed by most quality goal criteria; platelets were less reliably measured, with 80% deemed suitable for low platelet counts, but only 30% for high platelet counts, and automated differential leukocyte counts were generally considered unsuitable for clinical use with fewer than 40% of analyzers meeting the least stringent quality goal requirements. Fewer than 50% of analyzers were able to meet requirements for statistical quality control for any measurand. These findings reflect the current status of in-clinic hematology analyzer performance and provide a basis for future evaluations of the quality of veterinary laboratory testing. © 2016 American Society for Veterinary Clinical Pathology.

This current study investigated which angle of canine inclination (angle between canine tooth axis (CA-line) and the line between the lateral canthus and the ipsilateral labial angle (EM-line)) is perceived to be most attractive in a smile. The second objective was to determine whether laymen and dental experts share the same opinion. A Q-sort assessment was performed with 48 posed smile photographs to obtain two models of neutral facial attractiveness. Two sets of images (1 male model set, 1 female model set), each containing seven images with incrementally altered canine and posterior teeth inclinations, were generated. The images were ranked for attractiveness by three groups (61 laymen, 59 orthodontists, 60 dentists). The images with 0° inclination, that is CA-line (maxillary canine axis) parallel to EM-line (the line formed by the lateral canthus and the ipsilateral corner of the mouth) (male model set: 54·4%; female model set: 38·9%), or -5° (inward) inclination (male model set: 20%; female model set: 29·4%) were perceived to be most attractive within each set. Images showing inward canine inclinations were regarded to be more attractive than those with outward inclinations. Dental experts and laymen were in accordance with the aesthetics. Smiles were perceived to be most attractive when the upper canine tooth axis was parallel to the EM-line. In reconstructive or orthodontic therapy, it is thus important to incline canines more inwardly than outwardly. © 2014 John Wiley & Sons Ltd.

New COMPASS DAQ

Energy Technology Data Exchange (ETDEWEB)

Bai, Yunpeng; Konorov, Igor

2015-07-01

This contribution focuses on the deployment and first results of the new FPGA-based data acquisition system (DAQ) of the COMPASS experiment. Since 2002, the number of channels increased to approximately 300000, trigger rate increased to 30 kHz; the average event size remained roughly 35 kB. In order to handle the increased data rates, the new DAQ system with custom FPGA based data handling cards (DHC) had been decided to replace the event building network. The DHCs are equipped with 16 high speed serial links, 2GB of DDR3 memory with bandwidth of 6 GB/s, Gigabit Ethernet connection, and COMPASS Trigger Control System. It uses two different firmware versions: multiplexer and switch. The multiplexer DHC can combine 15 incoming links into one outgoing, whereas the switch combines 8 data streams from multiplexers and using information from look-up table sends the full events to the readout engine servers equipped by spillbuffer PCI-Express cards that receive the data. Both types of DHC can buffer data which allows to distribute the load over the cycle of accelerator. For the purposes of configuration, run control, and monitoring, software tools are developed. Communication between processes in the system is implemented using the DIM library. The DAQ is fully configurable from the web interface. New DAQ system has been deployed for the pilot run starting from the September 2014. In the poster, the preliminary performance and stability results of the new DAQ are presented and compared with the original system in more detail.

Full Text Available Objective: Self-stigma in overweight and obese individuals has strong associations with impairment in mental and global health. This study sought to explore self-compassion as a psychological resource in the self-stigma process. Methods: In a 2012 representative German population survey of N = 1,158 overweight and obese individuals, self-compassion was examined as a mediator between self-stigma and mental and physical health outcomes, including BMI (kg/m2, using structural equation modeling and controlling for sociodemographic factors. Results: Psychological variables were assessed using validated self-report questionnaires. Self-compassion partially mediated the relationships between self-stigma and depression, somatic symptoms, and health status / quality of life, lowering the predictive effect of self-stigma on the outcomes by approximately one-third. In contrast, self-compassion, because it was unrelated to BMI, did not mediate the association between self-stigma and BMI. Conclusion: Self-compassion has the potential to act as a buffer against the mental and global health detriments of self-stigma in overweight and obesity and could thus represent a target for interventions to reduce self-stigma and prevent these health impairments. In order to influence the association between self-stigma and BMI, self-compassion should conceptually be linked to weight management.

Association among self-compassion, childhood invalidation, and borderline personality disorder symptomatology in a Singaporean sample.

Linehan's biosocial theory posits that parental invalidation during childhood plays a role in the development of borderline personality disorder symptoms later in life. However, little research has examined components of the biosocial model in an Asian context, and variables that may influence the relationship between childhood invalidation and borderline symptoms. Self-compassion is increasingly regarded as an adaptive way to regulate one's emotions and to relate to oneself, and may serve to moderate the association between invalidation and borderline symptoms. The present study investigated the association among childhood invalidation, self-compassion, and borderline personality disorder symptoms in a sample of Singaporean undergraduate students. Two hundred and ninety undergraduate students from a large Singaporean university were recruited and completed measures assessing childhood invalidation, self-compassion, and borderline personality disorder symptoms. Analyses using multiple regression indicated that both childhood invalidation and self-compassion significantly predicted borderline personality disorder symptomatology. Results from moderation analyses indicated that relationship between childhood invalidation and borderline personality disorder symptomatology did not vary as a function of self-compassion. This study provides evidence in support of aspects of the biosocial model in an Asian context, and demonstrates a strong association between self-compassion and borderline personality disorder symptoms, independent of one's history of parental invalidation during childhood.

Exploring compassion: implications for contemporary nursing. Part 2.

Science.gov (United States)

Straughair, Collette

A range of contemporary political and professional literature endorse the principle of compassion in nursing as a core and underpinning philosophy fundamental to the profession. However, despite pledges to ensure that compassion lies at the heart of nursing, the concept has not been clearly defined. It is evident that uncovering the true meaning is complex and challenging owing to its subjective nature. In light of this, several implications must be considered. Effective student nurse recruitment is essential to ensure that the most appropriate individuals are selected. Contemporary marketing campaigns must be implemented, and recruitment strategies developed, which consider specific values and attitudes. Service user involvement in recruitment and selection, curriculum planning and learning and teaching strategies, and post-qualification education, can enhance nurses' understanding of the patient perspective and make headway in embedding compassion as a core nursing value. Additionally, effective role modelling in practice which demonstrates high-quality compassionate nursing care is essential. Nurses must be adequately supported in the clinical environment to facilitate compassionate behaviours and clinical leadership at all levels must uphold political and professional pledges to achieve this. Consideration of these implications for practice is essential to ensure that nurses are able to respond to patients with humanity and kindness, and deliver high-quality, compassionate care to all.

Barriers to Medical Compassion as a Function of Experience and Specialization: Psychiatry, Pediatrics, Internal Medicine, Surgery, and General Practice.

Fernando, Antonio T; Consedine, Nathan S

Compassion is an expectation of patients, regulatory bodies, and physicians themselves. Most research has, however, studied compassion fatigue rather than compassion itself and has concentrated on the role of the physician. The Transactional Model of Physician Compassion suggests that physician, patient, external environment, and clinical factors are all relevant. Because these factors vary both across different specialities and among physicians with differing degrees of experience, barriers to compassion are also likely to vary. We describe barriers to physician compassion as a function of specialization (psychiatry, general practice, surgery, internal medicine, and pediatrics) and physician experience. We used a cross-sectional study using demographic data, specialization, practice parameters, and the Barriers to Physician Compassion Questionnaire. Nonrandom convenience sampling was used to recruit 580 doctors, of whom 444 belonged to the targeted speciality groups. The sample was characterized before conducting a factorial Multivariate Analysis of Covariance and further post hoc analyses. A 5 (speciality grouping) × 2 (more vs. less physician experience) Multivariate Analysis of Covariance showed that the barriers varied as a function of both speciality and experience. In general, psychiatrists reported lower barriers, whereas general practitioners and internal medicine specialists generally reported greater barriers. Barriers were generally greater among less experienced doctors. Documenting and investigating barriers to compassion in different speciality groups have the potential to broaden current foci beyond the physician and inform interventions aimed at enhancing medical compassion. In addition, certain aspects of the training or practice of psychiatry that enhance compassion may mitigate barriers to compassion in other specialities.

Leiberg, Susanne; Klimecki, Olga; Singer, Tania

2011-01-01

Compassion has been suggested to be a strong motivator for prosocial behavior. While research has demonstrated that compassion training has positive effects on mood and health, we do not know whether it also leads to increases in prosocial behavior. We addressed this question in two experiments. In Experiment 1, we introduce a new prosocial game, the Zurich Prosocial Game (ZPG), which allows for repeated, ecologically valid assessment of prosocial behavior and is sensitive to the influence of reciprocity, helping cost, and distress cues on helping behavior. Experiment 2 shows that helping behavior in the ZPG increased in participants who had received short-term compassion training, but not in participants who had received short-term memory training. Interindividual differences in practice duration were specifically related to changes in the amount of helping under no-reciprocity conditions. Our results provide first evidence for the positive impact of short-term compassion training on prosocial behavior towards strangers in a training-unrelated task. PMID:21408020

Integrative Review of Facility Interventions to Manage Compassion Fatigue in Oncology Nurses.

Oncology nurses are regularly exposed to high-stress situations that may lead to compassion fatigue, and many institutions have implemented interventions to reduce burnout in nurses, but knowledge on the feasiblity, effectiveness, and nurses' experience of interventions is lacking.
. Electronic search of literature published from 1992-2015 was performed to evaluate in-facility interventions to manage compassion fatigue in oncology nurses. Databases used included CINAHL®, PubMed, Web of Science, Google Scholar, and PsycINFO®. 
. The goal was to evaluate the effectiveness, feasibility, and nurses' experience of interventions to manage compassion fatigue. The study designs, methods, and limitations were independently screened by the authors. 
. Of 164 studies, 31 met eligibility criteria. 
. The majority of the studies were conducted in Western countries, which suggests the need for additional research in other settings to determine effective interventions that address compassion fatigue and stress cross-culturally. Quantitative and qualitative studies failed to gain high scores in terms of quality. Limited conclusions can be drawn from small studies that report on outcomes with many confounding variables, such as turnover rate or general health of nurses, from a single institution. 
. Lack of empirical precision in evaluating the effectiveness, feasibility, and nurses' experiences of interventions indicates a need for future, more rigorously designed experimental studies. Because of the global increase in the number of patients being diagnosed and living with cancer, oncology nurses should be able to recognize and manage compassion fatigue.

Ageist attitudes block young adults' ability for compassion toward incapacitated older adults.

Upon encountering older adults, individuals display varying degrees of prosocial attitudes and behaviors. While some display compassion and empathy, others draw away and wish to maintain their distance from them. The current study examined if and how ageist attitudes influence the association between the sight of physical incapacity in older age and compassionate reactions toward them. We predicted that ageist attitudes would interfere with the ability to respond to them with compassion. Young adults (N = 149, ages 19-29) were randomly distributed into two experimental conditions, each viewing a short video portraying different aspects of older adult physicality; one group viewed older adults displaying incapacitated behavior, and the other viewed fit behavior. Participants subsequently filled out scales assessing aging anxieties, and ageist and compassionate attitudes. Ageism was associated with reduced compassion toward the figures. Moreover, viewing incapacitated older adults led to increased concern toward them and perceived efficacy in helping them. However, significant interactions proved that higher scores of ageism in response to the videos led to increased need for distance and reduced efficacy toward incapacitated adults, an effect not observed among subjects with lower ageism scores. Ageism seems to be a factor which disengages individuals from older adults displaying fragility, leading them to disregard social norms which dictate compassion. The results are discussed from the framework of terror management theory, as increased mortality salience and death-related thoughts could have led to the activation of negative attitudes which, in turn, reduce compassion.

Light-dependent magnetoreception: orientation behaviour of migratory birds under dim red light.

Wiltschko, Roswitha; Munro, Ursula; Ford, Hugh; Stapput, Katrin; Wiltschko, Wolfgang

2008-10-01

Magnetic compass orientation in migratory birds has been shown to be based on radical pair processes and to require light from the short wavelength part of the spectrum up to 565 nm Green. Under dim red light of 645 nm wavelength and 1 mW m(-2) intensity, Australian silvereyes and European robins showed a westerly tendency that did not change between spring and autumn, identifying it as a 'fixed direction' response. A thorough analysis revealed that this orientation did not involve the inclination compass, but was a response based on the polarity of the magnetic field. Furthermore, in contrast to the orientation under short-wavelength light, it could be disrupted by local anaesthesia of the upper beak where iron-containing receptors are located, indicating that it is controlled by these receptors. The similarity of the response under dim red light to the response in total darkness suggests that the two responses may be identical. These findings indicate that the observed 'fixed direction' response under dim red light is fundamentally different from the normal compass orientation, which is based on radical pair processes.

The Role of Self-Compassion in Buffering Symptoms of Depression in the General Population.

Directory of Open Access Journals (Sweden)

Annett Körner

Full Text Available Self-compassion, typically operationalized as the total score of the Self-Compassion Scale (SCS; Neff, 2003b, has been shown to be related to increased psychological well-being and lower depression in students of the social sciences, users of psychology websites and psychotherapy patients. The current study builds on the existing literature by examining the link between self-compassion and depressive symptomatology in a sample representative of the German general population (n = 2,404. The SCS subscales of self-judgment, isolation, and over-identification, and the "self-coldness", composite score, which encompass these three negative subscales, consistently differed between subsamples of individuals without any depressive symptoms, with any depressive syndromes, and with major depressive disorder. The contribution of the positive SCS subscales of self-kindness, common humanity, and mindfulness to the variance in depressive symptomatology was almost negligible. However, when combined to a "self-compassion composite", the positive SCS subscales significantly moderated the relationship between "self-coldness" and depressive symptoms in the general population. This speaks for self-compassion having the potential to buffer self-coldness related to depression--providing an argument for interventions that foster self-caring, kind, and forgiving attitudes towards oneself.

A computer code COMPASS based on compartment model approach is developed to calculate the near-field source term of the High-Level-Waste repository under unsaturated conditions. COMPASS is applied to evaluate the expected performance of Richard's (capillary) barriers as backfills to divert infiltrating groundwater at Yucca Mountain. Comparing the release rates of four typical nuclides with and without the Richard's barrier, it is shown that the Richard's barrier significantly decreases the peak release rates from the Engineered-Barrier-System (EBS) into the host rock

Self-compassion moderates the perfectionism and depression link in both adolescence and adulthood.

Directory of Open Access Journals (Sweden)

Madeleine Ferrari

Full Text Available Psychological practitioners often seek to directly change the form or frequency of clients' maladaptive perfectionist thoughts, because such thoughts predict future depression. Indirect strategies, such as self-compassion interventions, that seek to change clients' relationships to difficult thoughts, rather than trying to change the thoughts directly could be just as effective. This study aimed to investigate whether self-compassion moderated, or weakened, the relationship between high perfectionism and high depression symptoms in both adolescence and adulthood.The present study utilised anonymous self-report questionnaires to assess maladaptive perfectionism, depression, and self-compassion across two samples covering much of the lifespan. Questionnaires were administered in a high school setting for the adolescent sample (Study 1, Mage = 14.1 years, n = 541, and advertised through university and widely online to attract a convenience sample of adults (Study 2, Mage = 25.22 years, n = 515.Moderation analyses revealed that self-compassion reduced the strength of relationship between maladaptive perfectionism and depression in our adolescent Study 1 (β = -.15, p < .001, R2 = .021. and our adult study 2 (β = -.14, p < .001, R2 = .020.Cross-sectional self-reported data restricts the application of causal conclusions and also relies on accurate self-awareness and willingness to respond to questionnaire openly.The replication of this finding in two samples and across different age-appropriate measures suggests that self-compassion does moderate the link between perfectionism and depression. Self-compassion interventions may be a useful way to undermine the effects of maladaptive perfectionism, but future experimental or intervention research is needed to fully assess this important possibility.

Body image satisfaction significantly influences self-esteem in female adolescents. Increased reports of lowered satisfaction in this population have raised concerns regarding their compromised self-esteem. This research study, therefore, sought to identify a culturally significant moderator of the association between body image satisfaction and self-esteem in Thai female adolescents. Orientation toward self-compassion, found to be particularly high in Thailand, was examined. A total of 302 Thai female undergraduates from three large public and private universities in the Bangkok metropolitan area responded to a set of questionnaires, which measured demographic information, body image satisfaction, self-compassion, and self-esteem. Data were analyzed using correlation and multiple regression analyses. Self-compassion was tested as a moderator of the relationship between body image satisfaction and self-esteem. Although its effect was relatively small, self-compassion significantly moderated the positive relationship between body image satisfaction and self-esteem. The relationship became less stringent for those with high self-compassion. The cultivation of self-compassion was recommended in female adolescents. In addition to moderating the association between body image satisfaction and self-esteem, the benefits to health and well-being of generalizing this cultivation are discussed.

An innovative solar cell based on inclined p-i-n nanowire array is designed and analyzed. The results show that the inclined geometry can sufficiently increase the conversion efficiency of solar cells by enhancing the absorption of light in the active region. By tuning the nanowire array density, nanowire diameter, nanowire length, as well as the proportion of intrinsic region of the inclined nanowire solar cell, a remarkable efficiency in excess of 16% can be obtained in GaAs. Similar results have been obtained in InP and Si nanowire solar cells, demonstrating the universality of the performance enhancement of inclined nanowire arrays.

Mantzios, Michail; Wilson, J C

2014-01-01

Research on the usefulness of mindfulness and self-compassion for dieting has focused on meditative practices. However, meditation can be difficult to maintain, especially while dieting. Thus, the present research attempted to induce mindfulness and self-compassion by using food diaries that required the participant to either focus on concrete (i.e. how they are eating) construals or abstract (i.e. why they are eating) construals. The concrete construals were expected to increase mindfulness and self-compassion, as well as decrease avoidance and negative thoughts (which would further aid the development of mindfulness and self-compassion). Study 1 found that mindfulness and self-compassion mediated the inverse relationship of avoidance and negative thoughts with weight loss. Study 2 showed that concrete construal diaries increased mindfulness and self-compassion, decreased avoidance and negative thoughts, and supported weight loss significantly more than the abstract construal diaries. Study 3, then, compared the concrete construal diaries with a mindful self-compassionate meditation programme. There was no difference in weight loss at the end of the intervention, but at a three-month follow-up, the diaries performed better at weight maintenance. Thus, the concrete construal diaries may promote mindfulness and self-compassion and potentially promote long-term weight loss.

2017-12-01

This study investigated whether single-session self-compassion and self-esteem writing tasks ameliorate the body image concerns evoked by a negative body image induction. Ninety-six female university students aged 17-25 years (M age =19.45, SD=1.84) were randomly assigned to one of three writing treatment groups: self-compassion, self-esteem, or control. After reading a negative body image scenario, participants completed scales measuring state body appreciation, body satisfaction, and appearance anxiety. They then undertook the assigned writing task, and completed the three measures again, both immediately post-treatment and at 2-week follow-up. The self-compassion writing group showed higher post-treatment body appreciation than the self-esteem and control groups, and higher body appreciation than the control group at follow-up. At post-treatment and follow-up, self-compassion and self-esteem writing showed higher body satisfaction than the control. The groups did not differ on appearance anxiety. Writing-based interventions, especially those that enhance self-compassion, may help alleviate certain body image concerns. Copyright © 2017 Elsevier Ltd. All rights reserved.

The COMPASS experiment at the SPS accelerator at CERN uses a large scale Ring Imaging CHerenkov detector (RICH) to identify pions, kaons and protons in a wide momentum range. For the data taking in 2006, the COMPASS RICH has been upgraded in the central photon detection area (25% of the surface) with a new technology to detect Cherenkov photons at very high count rates of several 10^6 per second and channel and a new dead-time free read-out system, which allows trigger rates up to 100 kHz. The Cherenkov photons are detected by an array of 576 visible and ultra-violet sensitive multi-anode photomultipliers with 16 channels each. The upgraded detector showed an excellent performance during the 2006 data taking.

The purpose of this study is to explore the effects of a daily mindfulness practice and 2 types of journaling on participants' development of self-compassion. This was a between-groups design. All participants in a graduate counseling course engaged in a short daily mindfulness practice at the beginning of every class. Participants were randomly assigned to a counseling journal or a gratitude journal group. Participants were to write in their journals 2 to 5 times a week for the duration of the class. Participants completed the Self-Compassion Scale (Neff, 2003) and a questionnaire created by the 1st author before any mindfulness sessions were held and again at the completion of the course. Participants' level of self-compassion increased from pretest to posttest. The self-compassion scores of participants who kept counseling journals increased more than did those of participants who kept gratitude journals. Qualitative data indicated that participants believed that mindfulness was an important quality for clinicians to possess and that they were accepting of the daily mindfulness practice. Engaging in a 12-min daily mindfulness practice utilizing simple yoga postures, breath work, reflective writing, and journaling done at a separate time appears to be an effective technique for increasing students' levels of self-compassion. Maintaining a counseling journal as opposed to a gratitude journal appears to enhance the effect of the daily mindfulness practice on self-compassion.

Child maltreatment, including abuse (physical, emotional, and sexual) and neglect (physical and emotional), is positively associated with depressive symptoms in adulthood. However, most studies have been conducted within a psychopathological framework and focused on underlying dysfunctional processes (e.g., insecure attachment styles, maladaptive schemas, and negative attribution styles). Protective factors that affect the relationship between child maltreatment and adult depressive symptoms are underexplored. Guided by emotion regulation theory and the perspective of positive psychology, we examined the roles of self-compassion and gratitude as protective factors in the relationship between child maltreatment and adult depressive symptoms in a sample of 358 college students. Results showed that psychological maltreatment (emotional abuse and emotional neglect) was associated with adult depressive symptoms through decreased self-compassion. Neglect (emotional neglect and physical neglect) and sexual abuse were associated with adult depressive symptoms through decreased gratitude. There was no association between physical abuse and depressive symptoms through either self-compassion or gratitude. Our findings suggest that clinical practices focusing on self-compassion and gratitude might help prevent the development of adult depressive symptoms among clients with a history of maltreatment in childhood.

Masculinity and barriers to seeking counseling: The buffering role of self-compassion.

Science.gov (United States)

Heath, Patrick J; Brenner, Rachel E; Vogel, David L; Lannin, Daniel G; Strass, Haley A

2017-01-01

Less than 1/3 of college men seek psychological help per year when experiencing mental health concerns. Many believe this is because socialized masculine norms are incongruent with help-seeking decisions. In line with this, adherence to masculine norms, like emotional control and self-reliance, is consistently linked to factors associated with lower use of counseling. Identifying constructs that buffer, or reduce, the relationship between masculine norm adherence and common barriers to seeking help, like help-seeking self-stigma and resistance to self-disclosing, could shed light on mechanisms through which effective interventions could be developed. As such, this study examined whether self-compassion, or the ability to show oneself kindness and understanding in the face of challenges, moderated the relationship between masculine norm adherence and both help-seeking self-stigma and the risks associated with self-disclosing to a counselor in a sample of 284 undergraduate men (Mage = 19.68, range = 18-30). Results indicate that self-compassion is associated with lower levels of help-seeking self-stigma and disclosure risks. Additionally, and perhaps more importantly, self-compassion buffered the relationship between overall masculine norm adherence and each of these barriers. Furthermore, when specific masculine norms were examined, self-compassion buffered the relationship between emotional control and disclosure risks. These results support the need for future research focused on the development and assessment of self-compassion based interventions aimed at decreasing the barriers undergraduate men experience toward seeking psychological help.

Social suffering and the culture of compassion in a morally divided China.

Science.gov (United States)

Kuah-Pearce, Khun Eng; Kleinman, Arthur; Harrison, Emily

2014-01-01

This collection of essays opens a critical examination of compassionate acts responding to social suffering in the intensely complex moral context of a rapidly changing and globalizing China. Jeanne Shea describes self-compassion among older women in China as a post-revolutionary response to changing opportunities and resistance to consumerism. Khun Eng Kuah-Pearce's essay frames the Buddhist organizations as NGOs and shows compassion being mobilized and its acts being spiritual-philanthropic, not political. The next three papers illuminate the complexity of mobility in a moral sea of changing values. Even as modernity facilitates movement of people away from suffering, the grinding of entangled moral experiences within the mobile group can be the cause of suffering. Shu-Min Huang critiques 'cultural petrification' as the diasporic Yunnan Chinese community in Thailand attempt to preserve the cultural forms and procedures of the world they left behind. Likewise, Richard Madsen shows that the idea of a universalized cultural heritage fails in the face of the 'micro-ecologies'. And yet the modern impulse to universalize beyond China has important implications for transnational compassion and cooperation. The work of the humanitarian organization Médecins Sans Frontières in China, discussed by Kuah-Pearce and Guiheux, challenges the universality of global humanitarian actions. Following the series of essays threaded across intersections of compassion, suffering, and a morally-divided China, the collection closes by looking at the West. Iain Wilkinson discusses the origins of social suffering as a focus of the social sciences, as well as the difficulties of making engaged compassion its task in a morally-divided world.

Insights on compassion and patient-centred nursing in intensive care: A constructivist grounded theory.

2018-04-01

To explore patient-centred nursing, compassion satisfaction and compassion fatigue from intensive care nurses' perspectives. Compassion satisfaction and compassion fatigue can influence critical care nurses' decisions to either continue or leave the profession, and could impact the compassionate patient-centred nursing care patients receive during their ICU admission. This qualitative research design was informed by Charmaz's Grounded Theory Constructivist methodology. In-depth interviews were conducted with 21 critical care nurses of two ICUs in Australia during 2016. Interview data were analysed using grounded theory processes. Findings reflected positive and negative impacts on critical care nurses' ability to deal compassionately with their patients. Effects on patient-centred nursing and critical care nurses' own well-being were revealed. A core category of "Expectations" emerged, explaining the tension between critical care nurses' biomedical, clinical skills and knowledge versus compassionate, patient-centred nursing care. This tension was clarified and expanded in subcategories of "Life in the Balance," "Passion and Pressure," "Understanding and Advocacy" and "Tenacity and Fragility". Providing patient-centred nursing may enhance critical care nurses' experience of compassion satisfaction, in turn impacting delivery of compassionate patient-centred nursing to generate a virtuous circle. Critical care nurses who feel respected and supported by their management team and colleagues experience feelings of compassion satisfaction, leading to greater engagement and care towards their patient. Systematically addressing critical care nurses' needs to successfully balance biomedical with compassionate nursing care may lead to greater well-being in the critical care nursing workforce and improve patient experience of intensive care. © 2017 John Wiley & Sons Ltd.

Professionalism, professionalization, expertise and compassion: a qualitative study of medical residents.

Phillips, Susan P; Dalgarno, Nancy

Formal and informal medical curricula convey expectations about professionalization, that is, the development of physician identity, and also about professionalism. This study examined whether, in general, junior residents experienced any dissonance between these roles and focused particularly on how they negotiated conflicts between compassion, self-care, duty and medical expertise. In 2015, purposive sampling was used to select 21 first-year residents at a Canadian medical school. Participants listened to a 5-min audio-recording narrated in either male or female voice. Facing compassion fatigue after three obstetrical disasters over less than 2 days the resident narrator asks to go home. Participants reacted in writing to questions about this request and relevant teaching/modelling. Responses were analyzed using a qualitative, exploratory, thematic research design. Four themes were identified: i) empathy, self-doubt and fear of weakness, ii) the need for support from and communication with physicians and others, iii) education received, and iv) professionalization outranks professionalism. Participants agreed that under the circumstances the narrator's care, compassion and request were appropriate. Never the less, many grappled with feeling that asking to be relieved of work demonstrated weakness and a shirking of responsibility. Respondents had received no formal teaching about balancing compassion for patients or self with professional duty. Preceptors' informal teaching and modeling valorized scientific disengagement above all else. What emerged was participants' drive to become detached clinicians who set aside emotional responses and interactions that could impede and be incompatible with professionalization. However, participants also recognized and lamented what was lost in such a transformation. In the transition from student to practitioner, trainees' views and the modeling they receive shift emotion and compassion, whether for self or patients, from

TRANSIT TIMING VARIATIONS FOR INCLINED AND RETROGRADE EXOPLANETARY SYSTEMS

2010-01-01

We perform numerical calculations of the expected transit timing variations (TTVs) induced on a hot-Jupiter by an Earth-mass perturber. Motivated by the recent discoveries of retrograde transiting planets, we concentrate on an investigation of the effect of varying relative planetary inclinations, up to and including completely retrograde systems. We find that planets in low-order (e.g., 2:1) mean-motion resonances (MMRs) retain approximately constant TTV amplitudes for 0 deg. 170 deg. Systems in higher order MMRs (e.g., 5:1) increase in TTV amplitude as inclinations increase toward 45 deg., becoming approximately constant for 45 deg. 135 deg. Planets away from resonance slowly decrease in TTV amplitude as inclinations increase from 0 deg. to 180 deg., whereas planets adjacent to resonances can exhibit a huge range of variability in TTV amplitude as a function of both eccentricity and inclination. For highly retrograde systems (135 deg. < i ≤ 180 deg.), TTV signals will be undetectable across almost the entirety of parameter space, with the exceptions occurring when the perturber has high eccentricity or is very close to an MMR. This high inclination decrease in TTV amplitude (on and away from resonance) is important for the analysis of the known retrograde and multi-planet transiting systems, as inclination effects need to be considered if TTVs are to be used to exclude the presence of any putative planetary companions: absence of evidence is not evidence of absence.

The orbital inclination of Cygnus XR-1 measured polarimetrically

International Nuclear Information System (INIS)

Dolan, J.F.; Tapia, S.

1989-01-01

The X-ray binary Cyg XR-1/HDE 226868 was observed polarimetrically over one orbit at three different optical wavelengths. The standard theory of Brown, et al. (1978) is used to derive an orbital inclination i = 62 deg (+5 deg, -37 deg), where the error is the 90-percent-confidence interval derived by the method of Simmons, et al. (1980). The value of the orbital inclination is significantly lower than values based on polarimetric observations. The difference is a result of the observational protocols used. A bias toward larger values of the inclination caused by the tidal distortion of the primary is still found in the present result. The inclination derived corresponds to a mass of the compact component of 6.3 solar masses, above the maximum mass of any degenerate configuration consistent with general relativity except a black hole. 37 refs

New York City social workers after 9/11: their attachment, resiliency, and compassion fatigue.

Tosone, Carol; Bettmann, Joanna E; Minami, Takuya; Jasperson, Rachael A

2010-01-01

This study examines the relationship between attachment classification, resiliency, and compassion fatigue in New York social workers following 9/11. We used single occasion, quasi-random sampling, surveying 481 social workers living in Manhattan. Hierarchical regression analyses revealed that secure attachment is predictive of the ability to cope with secondary traumatic stress as well as capacity for resilience, explaining approximately 7% of the variance in both compassion fatigue and resiliency. These findings suggest that secure attachment may serve as a source of resilience for social workers, immunizing them from significant compassion fatigue. Such findings have significant implications for clinicians working with traumatized populations.

Recent Results on Spectroscopy from COMPASS

Grube, Boris

2016-01-01

The COmmon Muon and Proton Apparatus for Structure and Spectroscopy (COMPASS) is a multi-purpose fixed-target experiment at the CERN Super Proton Synchrotron (SPS) aimed at studying the structure and spectrum of hadrons. The two-stage spectrometer has a good acceptance for charged as well as neutral particles over a wide kinematic range and is thus able to measure a wide range of reactions. Light mesons are studied with negative (mostly $\\pi^-$) and positive ($p$, $\\pi^+$) hadron beams with a momentum of 190 GeV/$c$. The light-meson spectrum is investigated in various final states produced in diffractive dissociation reactions at squared four-momentum transfers to the target between 0.1 and 1.0 (GeV/$c$)$^2$. The flagship channel is the $\\pi^-\\pi^+\\pi^-$ final state, for which COMPASS has recorded the currently largest data sample. These data not only allow for measuring the properties of known resonances with high precision, but also for searching for new states. Among these is a new resonance-like signal, t...

The COMPASS tokamak has began operation at the IPP Prague in December 2008. A new control system has been built using an ATCA-based real-time system developed at IST Lisbon. The control software is implemented on top of the MARTe real-time framework attaining control cycles as short as 50 μs, with a jitter of less than 1 μs. The controlled parameters, important for the plasma performance, are the plasma current, position of the plasma current center, boundary shape and horizontal and vertical velocities. These are divided in two control cycles: slow at 500 μs and fast at 50 μs. The project has two phases. First, the software implements a digital controller, similar to the analog one used during the COMPASS-D operation in Culham. In the slow cycle, the plasma current and position are measured and controlled with PID and feedforward controllers, respectively, the shaping magnetic field is preprogrammed. The vertical instability and horizontal equilibrium are controlled with the faster 50-μs cycle PID controllers. The second phase will implement a plasma-shape reconstruction algorithm and controller, aiming at optimized plasma performance. The system was designed to be as modular as possible by breaking the functional requirements of the control system into several independent and specialized modules. This splitting enabled tuning the execution of each system part and to use the modules in a variety of applications with different time constraints. This paper presents the design and overall performance of the COMPASS control software.

Binge eating disorder (BED) is associated with several psychological and medical problems, such as obesity. Approximately 30% of individuals seeking weight loss treatments present binge eating symptomatology. Moreover, current treatments for BED lack efficacy at follow-up assessments. Developing mindfulness and self-compassion seem to be beneficial in treating BED, although there is still room for improvement, which may include integrating these different but complimentary approaches. BEfree is the first program integrating psychoeducation-, mindfulness-, and compassion-based components for treating women with binge eating and obesity. To test the acceptability and efficacy up to 6-month postintervention of a psychological program based on psychoeducation, mindfulness, and self-compassion for obese or overweight women with BED. A controlled longitudinal design was followed in order to compare results between BEfree (n = 19) and waiting list group (WL; n = 17) from preintervention to postintervention. Results from BEfree were compared from preintervention to 3- and 6-month follow-up. BEfree was effective in eliminating BED; in diminishing eating psychopathology, depression, shame and self-criticism, body-image psychological inflexibility, and body-image cognitive fusion; and in improving obesity-related quality of life and self-compassion when compared to a WL control group. Results were maintained at 3- and 6-month follow-up. Finally, participants rated BEfree helpful for dealing with impulses and negative internal experiences. These results seem to suggest the efficacy of BEfree and the benefit of integrating different components such as psychoeducation, mindfulness, and self-compassion when treating BED in obese or overweight women. The current study provides evidence of the acceptability of a psychoeducation, mindfulness, and compassion program for binge eating in obesity (BEfree); Developing mindfulness and self-compassionate skills is an effective way of

Impact of Providing Compassion on Job Performance and Mental Health: The Moderating Effect of Interpersonal Relationship Quality.

Science.gov (United States)

Chu, Li-Chuan

2017-07-01

To examine the relationships of providing compassion at work with job performance and mental health, as well as to identify the role of interpersonal relationship quality in moderating these relationships. This study adopted a two-stage survey completed by 235 registered nurses employed by hospitals in Taiwan. All hypotheses were tested using hierarchical regression analyses. The results show that providing compassion is an effective predictor of job performance and mental health, whereas interpersonal relationship quality can moderate the relationships of providing compassion with job performance and mental health. When nurses are frequently willing to listen, understand, and help their suffering colleagues, the enhancement engendered by providing compassion can improve the provider's job performance and mental health. Creating high-quality relationships in the workplace can strengthen the positive benefits of providing compassion. Motivating employees to spontaneously exhibit compassion is crucial to an organization. Hospitals can establish value systems, belief systems, and cultural systems that support a compassionate response to suffering. In addition, nurses can internalize altruistic belief systems into their own personal value systems through a long process of socialization in the workplace. © 2017 Sigma Theta Tau International.

Development of an Inclined Plate Extractor-Separator for Immiscible Liquids

2009-10-01

Full Text Available A new inclined plates extractor-separator is developed for operation with immiscible liquids in which extraction and separation is achieved in one unit contrary to mixer settlers. The inclined plates extractor-separator combines turbulent jets for contacting, and an inclined plate for separation of the two phases. The inclined plates extractor-separator does not have any moving part inside the vessel. This feature makes it free from the mechanical problems associated with conventional apparatus. The proposed inclined plates extractor-separator was operated in batch mode under various operating conditions to evaluate its performance on the basis of extraction efficiency. Water (light phase was used as solvent to extract ethyl acetate from a heavy phase pool of tetrachloroethylene and ethyl acetate. The ethyl acetate content was analysed using chromatography. A hydrodynamic study was carried out using high speed photography to understand the mechanisms occurring during mass transfer across the two phases. Furthermore, it was found that the proposed inclined plate extractor-separator reduces the overall operating time by 67% and consumes only 13% of the power in comparison to a mixer-settler. A hydraulic power consumption comparison with a mixer settler and a gullwing extractor-separator is also presented.

This paper presented a numerical simulation for an inclined packed bed configuration for two-phase co-current downward flow. A two-phase Eulerian computational fluid dynamics (CFD) model was used to predict the hydrodynamic behaviour. Two different modelling strategies were compared, notably a straight tube with an artificially inclined gravity, and an inclined geometry with straight gravity. The effect of inclination angle of a packed bed on its gas-liquid flow segregation and liquid saturation spatial distribution was measured for varying inclinations and fluid velocities. The CFD model was adapted from a trickle-bed vertical configuration and based on the porous media concept. The predicted pressure drops for the inclined gravity were found to be insensitive to inclination. Therefore, simulations to study the parameters that influence the reduced liquid saturation were performed only with the inclined geometry case. Experimental data obtained using electrical capacitance tomography was used to validate the model predictions. The study showed that a trickle bed CFD model for vertically straight reactors can be effectively implemented in inclined reactor geometries. However, additional research is needed to formulate appropriate drag force closures which should be incorporated in the CFD model for improved quantitative estimation of inclined bed hydrodynamics. 22 refs., 10 figs.

Measuring nursing care and compassion: the McDonaldised nurse?

Science.gov (United States)

Bradshaw, A

2009-08-01

In June 2008 the UK government, supported by the Royal College of Nursing, stated that nursing care would be measured for compassion. This paper considers the implications of this statement by critically examining the relationship of compassion to care from a variety of perspectives. It is argued that the current market-driven approaches to healthcare involve redefining care as a pale imitation, even parody, of the traditional approach of the nurse as "my brother's keeper". Attempts to measure such parody can only measure artificial techniques and give rise to a McDonald's-type nursing care rather than heartfelt care. The arguments of this paper, although applied to nursing, also apply to medicine and healthcare generally.

Sky Compass Orientation in Desert Locusts-Evidence from Field and Laboratory Studies.

Science.gov (United States)

Homberg, Uwe

2015-01-01

Locusts are long-range migratory insects. At high population density, immature animals form marching hopper bands while adults take off and form huge swarms of millions of animals. At low population densities animals are solitarious, but likewise migrate, mostly during the night. Numerous studies aimed at predicting locust infestations showed that migrations both as hopper bands and as adults are largely downwind following seasonal shifts of the tropical convergence zone taking the animals to areas of rainfall. Only a few studies provided evidence for active orientation mechanisms, including the involvement of a sun compass. This scarcity of evidence stands in contrast to recent neurobiological data showing sophisticated neuronal adaptations suited for sky compass navigation. These include a special dorsal eye region with photoreceptors suited to analyze the polarization pattern of the sky and a system of topographically arranged sky compass neurons in the central complex of the brain. Laboratory experiments, moreover, demonstrated polarotaxis in tethered flying animals. The discrepancy of these findings call for more rigorous field studies on active orientation mechanisms in locusts. It remains to be shown how locusts use their internal sky compass during mass migrations and what role it plays to guide solitarious locusts in their natural habitat.

Polarised Drell-Yan measurements at $\\mathrm{COMPASS}$

CERN Document Server

Chiosso, Michela

2015-01-01

Much of the information that exists today about Transverse Momentum Dependent Parton Distribution Functions (TMDs) comes from SIDIS measurements with unpolarised and polarised beams and targets where they appear convoluted with fragmentation functions (FFs). Drell-Yan (DY) measurements are complementary to those by SIDIS experiments, as they allow to measure convolutions of only Parton Distribution Functions (PDFs) without involving FFs. Moreover, given the T-odd character of both Sivers and Boer-Mulders functions, the sign of these TMDs is expected to be reversed when observed from SIDIS or from DY. Measurements of SIDIS were performed by Compass in the period 2002 to 2007 and in 2010, using a naturally polarised μ+ beam and a solid state target polarised either longitudinally or transversely with respect to the beam direction. Now the COMPASS Experiment has the unique opportunity to access TMDs from single-polarised Drell-Yan processes as well, in the same kinematical domain of the SIDIS data and with the ...

The Berkeley Compass Project is a self-formed group of graduate and undergraduate students in the physical sciences at UC Berkeley. Our goals are to improve undergraduate physics education, provide opportunities for professional development, and increase retention of students from populations typically underrepresented in the physical sciences. For students who enter as freshmen, the core Compass experience consists of a summer program and several seminar courses. These programs are designed to foster a diverse, collaborative student community in which students engage in authentic research practices and regular self-reflection. Compass encourages undergraduates to develop an identity as a scientist from the beginning of their university experience.

Compassion fade: affect and charity are greatest for a single child in need.

Directory of Open Access Journals (Sweden)

Daniel Västfjäll

Full Text Available Charitable giving in 2013 exceeded $300 billion, but why do we respond to some life-saving causes while ignoring others? In our first two studies, we demonstrated that valuation of lives is associated with affective feelings (self-reported and psychophysiological and that a decline in compassion may begin with the second endangered life. In Study 3, this fading of compassion was reversed by describing multiple lives in a more unitary fashion. Study 4 extended our findings to loss-frame scenarios. Our capacity to feel sympathy for people in need appears limited, and this form of compassion fatigue can lead to apathy and inaction, consistent with what is seen repeatedly in response to many large-scale human and environmental catastrophes.

Inclined nanoimprinting lithography for 3D nanopatterning

International Nuclear Information System (INIS)

Liu Zhan; Bucknall, David G; Allen, Mark G

2011-01-01

We report a non-conventional shear-force-driven nanofabrication approach, inclined nanoimprint lithography (INIL), for producing 3D nanostructures of varying heights on planar substrates in a single imprinting step. Such 3D nanostructures are fabricated by exploiting polymer anisotropic dewetting where the degree of anisotropy can be controlled by the magnitude of the inclination angle. The feature size is reduced from micron scale of the template to a resultant nanoscale pattern. The underlying INIL mechanism is investigated both experimentally and theoretically. The results indicate that the shear force generated at a non-zero inclination angle induced by the INIL apparatus essentially leads to asymmetry in the polymer flow direction ultimately resulting in 3D nanopatterns with different heights. INIL removes the requirements in conventional nanolithography of either utilizing 3D templates or using multiple lithographic steps. This technique enables various 3D nanoscale devices including angle-resolved photonic and plasmonic crystals to be fabricated.

A worthy self is a caring self: Examining the developmental relations between self-esteem and self-compassion in adolescents.

2017-08-18

Self-compassion has been framed as a healthy alternative to self-esteem, as it is nonevaluative. However, rather than being alternatives, it may be that the two constructs develop in a mutually reinforcing way. The present study tested this possibility among adolescents. A large adolescent sample (N = 2,809; 49.8% female) reported levels of trait self-esteem and self-compassion annually for 4 years. Autoregressive cross-lagged structural equation models were used to estimate the reciprocal longitudinal relations between the two constructs. Self-esteem consistently predicted changes in self-compassion across the 4 years of the study, but not vice versa. Self-esteem appears to be an important antecedent of the development of self-compassion, perhaps because the capacity to extend compassion toward the self depends on one's appraisals of worthiness. These findings add important insights to our theoretical understanding of the development of self-compassion. © 2017 Wiley Periodicals, Inc.

Further, the analysis of a biological specimen's associated microbiome can also be performed using RNA-seq data and this application is gaining interest in the scientific community. There are many existing bioinformatics tools designed for analysis and visualization of transcriptome data. Despite the availability of an array of next generation sequencing (NGS analysis tools, the analysis of RNA-seq data sets poses a challenge for many biomedical researchers who are not familiar with command-line tools. Here we present RNA CoMPASS, a comprehensive RNA-seq analysis pipeline for the simultaneous analysis of transcriptomes and metatranscriptomes from diverse biological specimens. RNA CoMPASS leverages existing tools and parallel computing technology to facilitate the analysis of even very large datasets. RNA CoMPASS has a web-based graphical user interface with intrinsic queuing to control a distributed computational pipeline. RNA CoMPASS was evaluated by analyzing RNA-seq data sets from 45 B-cell samples. Twenty-two of these samples were derived from lymphoblastoid cell lines (LCLs generated by the infection of naïve B-cells with the Epstein Barr virus (EBV, while another 23 samples were derived from Burkitt's lymphomas (BL, some of which arose in part through infection with EBV. Appropriately, RNA CoMPASS identified EBV in all LCLs and in a fraction of the BLs. Cluster analysis of the human transcriptome component of the RNA CoMPASS output clearly separated the BLs (which have a germinal center-like phenotype from the LCLs (which have a blast-like phenotype with evidence of activated MYC signaling and lower interferon and NF-kB signaling in the BLs. Together, this analysis illustrates the utility of RNA CoMPASS in the simultaneous analysis of transcriptome and metatranscriptome data. RNA CoMPASS is freely

Pool Boiling CHF in Inclined Narrow Annuli

Pool boiling heat transfer has been studied extensively since it is frequently encountered in various heat transfer equipment. Recently, it has been widely investigated in nuclear power plants for application to the advanced light water reactors designs. Through the review on the published results it can be concluded that knowledge on the combined effects of the surface orientation and a confined space on pool boiling heat transfer is of great practical importance and also of great academic interest. Fujita et al. investigated pool boiling heat transfer, from boiling inception to the critical heat flux (CHF, q' CHF ), in a confined narrow space between heated and unheated parallel rectangular plates. They identified that both the confined space and the surface orientation changed heat transfer much. Kim and Suh changed the surface orientation angles of a downward heating rectangular channel having a narrow gap from the downward-facing position (180 .deg.) to the vertical position (90 .deg.). They observed that the CHF generally decreased as the inclination angle (θ ) increased. Yao and Chang studied pool boiling heat transfer in a confined heat transfer for vertical narrow annuli with closed bottoms. They observed that when the gap size ( s ) of the annulus was decreased the effect of space confinement to boiling heat transfer increased. The CHF was occurred at much lower value for the confined space comparing to the unconfined pool boiling. Pool boiling heat transfer in narrow horizontal annular crevices was studied by Hung and Yao. They concluded that the CHF decreased with decreasing gap size of the annuli and described the importance of the thin film evaporation to explain the lower CHF of narrow crevices. The effect of the inclination angle on the CHF on countercurrent boiling in an inclined uniformly heated tube with closed bottoms was also studied by Liu et al. They concluded that the CHF reduced with the inclination angle decrease. A study was carried out

Wellbore position calculations are typically performed by measuring azimuth and inclination at 10 to 30 meter intervals and using interpolation techniques to determine the borehole position between survey stations. The input parameters are measured depth (MD), azimuth and inclination, where the two parameters are measured with an MWD tool. Output parameters are the geometric coordinates; true value depth (TVD), north and east. By improving the accuracy of the inclination measurement reduces the uncertainty of the calculated TVD value, resulting in increased confidence in wellbore position. Significant improvements in quality control can be achieved by using multiple sensors. This paper describes a set of quality control parameters that can be used to verify individual sensor performance and a method for calculating TVD uncertainty in horizontal wells, using a single sensor or a combination of sensors. 6 refs., 5 figs.

Lung cancer patients and their spouses report high rates of distress. Due to the increasing popularity of and evidence for mindfulness-based interventions in cancer, mindfulness and self-compassion have been identified as potentially helpful skills when coping with cancer. This dyadic study examined how mindfulness and self-compassion are related to psychological distress and communication about cancer in couples facing lung cancer. Using the actor-partner interdependence model, self-reported mindfulness, self-compassion, psychological distress and communication about cancer were analyzed in a cross-sectional sample of 88 couples facing lung cancer. Regarding psychological distress, no difference was found between patients and spouses. In both partners, own levels of mindfulness ( B  = -0.19, p  = .002) and self-compassion ( B  = -0.45, p  dyadic level, own self-compassion was less strongly associated with distress if the partner reported high self-compassion ( B  = 0.03, p  = .049). Regarding communication about cancer, patients reported to communicate more openly with their partner than with spouses. However, after controlling for gender, this difference was no longer significant. In both partners, own self-compassion ( B  = 0.03, p  = .010) was significantly associated with own communication while mindfulness was not. A trend showed that mindfulness of the partner was related to more open communication in the individual ( B  = 0.01, p  = .080). These findings give a first indication that mindfulness and self-compassion skills may go beyond the individual and could impact couple functioning. Future research should examine whether couples facing (lung) cancer may benefit from programs in which mindfulness and self-compassion are cultivated.

We review the spin radical pair mechanism which is a promising explanation of avian navigation. This mechanism is based on the dependence of product yields on 1) the hyperfine interaction involving electron spins and neighboring nuclear spins and 2) the intensity and orientation of the geomagnetic field. One surprising result is that even at ambient conditions quantum entanglement of electron spins can play an important role in avian magnetoreception. This review describes the general scheme of chemical reactions involving radical pairs generated from singlet and triplet precursors; the spin dynamics of the radical pairs; and the magnetic field dependence of product yields caused by the radical pair mechanism. The main part of the review includes a description of the chemical compass in birds. We review: the general properties of the avian compass; the basic scheme of the radical pair mechanism; the reaction kinetics in cryptochrome; quantum coherence and entanglement in the avian compass; and the effects of noise. We believe that the quantum avian compass can play an important role in avian navigation and can also provide the foundation for a new generation of sensitive and selective magnetic-sensing nano-devices.

Full Text Available The present study verifies the psychometric properties of the Slovak version of the Self-Compassion Scale through item response theory, factor-analysis, validity analyses and norm development. The surveyed sample consisted of 1,181 participants (34% men and 66% women with a mean age of 30.30 years (SD = 12.40. Two general factors (Self-compassionate responding and Self-uncompassionate responding were identified, whereas there was no support for a single general factor of the scale and six subscales. The results of the factor analysis were supported by an independent sample of 676 participants. Therefore, the use of total score for the whole scale would be inappropriate. In Slovak language the Self-Compassion Scale should be used in the form of two general subscales (Self-compassionate responding and Self-uncompassionate responding. In line with our theoretical assumptions, we obtained relatively high Spearman’s correlation coefficients between the Self-Compassion Scale and related external variables, demonstrating construct validity for the scale. To sum up, the Slovak translation of The Self-Compassion Scale is a reliable and valid instrument that measures Self-compassionate responding and Self-uncompassionate responding.

Stratified flow model for convective condensation in an inclined tube

Highlights: ► Convective condensation in an inclined tube is modelled. ► The heat transfer coefficient is the highest for about 20° below the horizontal. ► Capillary forces have a strong effect on the liquid–vapour interface shape. ► A good agreement between the model and the experimental results was observed. - Abstract: Experimental data are reported for condensation of R134a in an 8.38 mm inner diameter smooth tube in inclined orientations with a mass flux of 200 kg/m 2 s. Under these conditions, the flow is stratified and there is an optimum inclination angle, which leads to the highest heat transfer coefficient. There is a need for a model to better understand and predict the flow behaviour. In this paper, the state of the art of existing models of stratified two-phase flows in inclined tubes is presented, whereafter a new mechanistic model is proposed. The liquid–vapour distribution in the tube is determined by taking into account the gravitational and the capillary forces. The comparison between the experimental data and the model prediction showed a good agreement in terms of heat transfer coefficients and pressure drops. The effect of the interface curvature on the heat transfer coefficient has been quantified and has been found to be significant. The optimum inclination angle is due to a balance between an increase of the void fraction and an increase in the falling liquid film thickness when the tube is inclined downwards. The effect of the mass flux and the vapour quality on the optimum inclination angle has also been studied.

Recent results for the performance of a novel double crystal monochromator subjected to high heat loads on an APS prototype undulator at the Cornell High Energy Synchrotron Source (CHESS) are presented. The monochromator was designed to achieve symmetric diffraction from asymmetric planes to spread out the beam footprint thereby lowering the incident power density. Both crystals had (111) oriented surfaces and were arranged such that the beam was diffracted from the (11 bar 1) planes at 5 KeV. Rocking curves with minimal distortion were obtained at a ring electron current of 100 mA. This corresponded to 380 Watts total power and an average power density of 40 Watts/mm 2 normal to the incident beam. These results are compared to data obtained from the same crystals in the standard geometry (diffracting planes parallel to surface). The footprint area in the inclined case was three times that of the standard case. We also obtained rocking curve data for the (333) reflection at 15 KeV for both standard and inclined cases, and these data also showed a minimal distortion only for the inclined case. In addition, thermal data were obtained via infrared pyrometry. Liquid gallium flow rates of up to 2 gallons per minute were investigated. The diffraction data revealed a dramatically improved performance for the inclined crystal case

Mechanisms of Change in the Relationship between Self-Compassion, Emotion Regulation, and Mental Health: A Systematic Review.

Research suggests that self-compassion may improve mental health by promoting emotion regulation (Berking & Whitley, ). This review aimed to identify studies which investigated the relationship between self-compassion, emotion regulation, and mental health in order to examine the role of emotional regulation as a mechanism of change. Searches were conducted in PsycINFO, CINAHL, Medline complete, Web of Science and Scopus databases. Inclusion criteria required publications to be: peer reviewed, published in English, contain validated measures of self-compassion and emotion regulation, and report a direct analysis on the relationship between these constructs. The search yielded five studies which met inclusion criteria. Emotion regulation significantly mediated the relationship between self-compassion and mental health. This pattern was consistent across community and clinical samples, for a range of mental health symptoms including stress, depression, and post-traumatic stress disorder. A critical limitation of the review was that all included studies used cross-sectional data, limiting interpretations regarding causation. Results provide preliminary evidence that emotion regulation may be a mechanism of change in the relationship between self-compassion and mental health. Self-compassion may be a pertinent preliminary treatment target for individuals who avoid experiences of emotions. © 2018 The International Association of Applied Psychology.

The COMPASS experiment is one of the few experiments in the world capable of studying the internal structure of protons with high precision. In 2016 the experiment will use the 160 GeV high energy positive and negative muon beams and a new liquid-hydrogen target. One of the main goals is the study of the virtual Compton scattering on the proton when a high energy muon scatters on a proton to produce a single photon. The analysis of the cross section and angular distributions will provide a 3 dimensional structure of the proton by determining the correlations between position and momentum of the elementary quarks and gluons inside the proton. The COMPASS experiment comprises a high resolution forward spectrometer with many trackers for charged particles, detectors for particle identification as three electromagnetic calorimeters and a recoil proton detector around the target.

Measurement of the charged-pion polarisability at COMPASS

CERN Multimedia

CERN. Geneva

2015-01-01

For more than a decade, COMPASS has been tackling the measurement of the electromagnetic polarizability of the charged pion, which describes the stiffness of the pion against deformation in electromagnetic fields. Previous experiments date back to the 1980's in Serpukhov (Russia), where the Primakoff method for realizing interactions of charged pions with quasi-real photons was first employed. Later also other techniques in photon-nucleon and photon-photon collisions were carried out at different machines. The COMPASS measurement demonstrates that the charged-pion polarizability is significantly smaller than the previous results, roughly by a factor two, with the smallest uncertainties realized so far. The pion polarisability is of fundamental interest in the low-energy sector of quantum chromodynamics. It is directly linked to the quark-gluon substructure and dynamics of the pion, the lightest bound system of strong interaction.

Radical-ion pair reactions are currently understood to underlie the biochemical magnetic compass of migratory birds. It was recently shown that radical-ion pair reactions form a rich playground for the application of quantum-information-science concepts and effects. We will show here that the intricate interplay between the quantum Zeno effect and the coherent excitation of radical-ion pairs leads to an exquisite angular sensitivity of the reaction yields. This results in a significant and previously unanticipated suppression of the avian compass heading error, opening the way to quantum engineering precision biological sensors.

1987-01-01

A steady-state single-phase natural circulation test was performed to clarify the effect of inclination by using a model of an integrated-type marine reactor. It was found that several types of flow pattern occur in the natural circulation loop corresponding to the range of inclination angle. Stable flow rates are sustained up to near 90 0 because of the occurrence of a driving force arising from those sections of the facility which were horizontal before the inclination. It was found that the temperature distribution in the steam generator at inclined attitude depends essentially only on the elevation z. The applicability of a one-dimensional analytical model was examined. It was clarified that employment of detailed U-turn flow paths, their correlation, and temperature-distribution function of core is essential for improvement. (orig.)

A major part of the future COMPASS program is dedicated to the investigation of the nucleon structure through Deeply Virtual Compton Scattering (DVCS) and Deeply Virtual Meson Production (DVMP). COMPASS will measure DVCS and DVMP reactions with a high intensity muon beam of 160 GeV and a 2.5 m-long liquid hydrogen target surrounded by a new TOF system. The availability of muon beams with high energy and opposite charge and polarization will allow to access the Compton form factor related to the dominant GPD H and to study the x B -dependence of the t-slope of the pure DVCS cross section and to study nucleon tomography. Projections on the achievable accuracies and preliminary results of pilot measurements will be presented.

The orbital inclination of A0620 - 00 measured polarimetrically

International Nuclear Information System (INIS)

Dolan, J.F.; Tapia, S.

1989-01-01

The mass of the degenerate primary in A0620 - 00 is inferred from its spectroscopic mass function to be not less than 3.2 solar masses, making it an excellent candidate for a black hole. The exact value of the mass depends on the orbital inclination. The inclination of a binary system can be determined from the shape of its Stokes parameter light curves if the linear polarization of the system varies as a function of orbital phase. A0620 - 00 over one 8-hour binary period was observed with the 4.5-m equivalent MMT. Its polarization in the visible is variable with orbital phase. The standard theory of Brown et al. (1978) was used to derive an orbital inclination of i = 57 deg (+20 deg, -50 deg), where the error is the 90-percent confidence interval. An inclination of i = 57 deg corresponds to a mass of the compact primary of 6.6 solar masses, but the large uncertainty in the measured value of the inclination allows the derived mass of A0620 - 00 to be as low as 3.8 solar masses. If this is taken to be the maximum mass of any degenerate configuration consistent with general relativity except a black hole, then the mass of A0620 - 00 is still not well enough determined to conclude that it must be a black hole. 21 refs

Meson Spectroscopy at COMPASS

Haas, F.

2009-01-01

In addition to constituent q q(bar) pair configurations, four quark states or gluonic excitations like hybrids or glueballs are also expected to contribute to the mesonic spectrum. The most promising way to identify such states allowed by QCD is the search for J PC quantum number combinations which are forbidden in the constituent quark model. The fixed target COMPASS experiment at CERN offers the opportunity to search for such states in the light quark sector with an unprecedented statistics. First studies of diffractive reactions of 190 GeV/c ions were carried out by COMPASS during a pilot run in 2004. In a first analysis, the three charged pion final state was studied. A Partial Wave Analysis (PWA) with 42 waves including acceptance corrections through a phase-space Monte Carlo simulation of the spectrometer was performed. The exotic π1 (1600) meson with quantum numbers J PC 1 -+ has been clearly established in the ρ-π decay channel with a mass of 1660 ± 0.010(stat) MeV and a width of 0.269 ± 0.021(stat) MeV. The final state with 5 charged pions was also investigated. Results from that study will also be presented. The improved detectors performance in 2008 allows us to study besides these channels further diffractively and centrally produced resonances, neutral ones as well as charged ones. First results of the ongoing analysis of the 2008 data taking period, using a 190 GeV/c pion beam on a hydrogen target will be given. (author)

Strength Calculation of Inclined Sections of Reinforced Concrete Elements under Transverse Bending

Science.gov (United States)

Filatov, V. B.

2017-11-01

The authors propose a design model to determine the strength of inclined sections of bent reinforced concrete elements without shear reinforcement for the action of transverse force taking into account the aggregate interlock forces in the inclined crack. The calculated dependences to find out the components of forces acting in an inclined section are presented. The calculated dependences are obtained from the consideration of equilibrium conditions of the block over the inclined crack. A comparative analysis of the experimental values of the failure loads of the inclined section and the theoretical values obtained for the proposed dependencies and normative calculation methods is performed. It is shown that the proposed design model makes it possible to take into account the effect the longitudinal reinforcement percentage has on the inclined section strength, the element cross section height without the introduction of empirical coefficients which contributes to an increase in the structural safety of design solutions including the safety of high-strength concrete elements.

Mobile interventions promoting positive body image are lacking. This study presents a randomized controlled evaluation of BodiMojo, a mobile application (app) intervention grounded in self-compassion to promote positive body image. A sample of 274 adolescents, mean (SD) age = 18.36 (1.34) years, 74% female, were allocated to a control group or used BodiMojo for 6 weeks. Appearance esteem, body image flexibility, appearance comparison, mood, and self-compassion were assessed at baseline, 6, and 12 weeks. Significant time by group interactions emerged for appearance esteem and self-compassion, with appearance esteem and self-compassion increasing in the intervention relative to the control group. These findings provide preliminary support for BodiMojo, a cost-effective mobile app for positive body image.

Extinction in galaxies affects their observed properties. In scenarios describing the distribution of dust and stars in individual disk galaxies, the amplitude of the extinction can be modulated by the inclination of the galaxies. In this work, we investigate the inclination dependency in composite spectra of star-forming disk galaxies from the Sloan Digital Sky Survey Data Release 5. In a volume-limited sample within a redshift range 0.065-0.075 and a r-band Petrosian absolute magnitude range -19.5 to -22 mag which exhibits a flat distribution of inclination, the inclined relative to face-on extinction in the stellar continuum is found empirically to increase with inclination in the g, r, and i bands. Within the central 0.5 intrinsic half-light radius of the galaxies, the g-band relative extinction in the stellar continuum for the highly inclined objects (axis ratio b/a = 0.1) is 1.2 mag, agreeing with previous studies. The extinction curve of the disk galaxies is given in the rest-frame wavelengths 3700-8000 A, identified with major optical emission and absorption lines in diagnostics. The Balmer decrement, Hα/Hβ, remains constant with inclination, suggesting a different kind of dust configuration and/or reddening mechanism in the H II region from that in the stellar continuum. One factor is shown to be the presence of spatially non-uniform interstellar extinction, presumably caused by clumped dust in the vicinity of the H II region.

Cross-sectional survey. To examine factors that may enhance and promote resilience in adults with spina bifida. Community-based disability organisations within Australia. Ninety-seven adults with a diagnosis of spina bifida (SB) completed a survey comprising of demographic questions in addition to standardised self-report measures of physical functioning (Craig Handicap Assessment and Reporting Technique), resilience (Connor-Davidson Resilience Scale, 10 item), self-esteem (Rosenberg Self-esteem Scale), self-compassion (Self-compassion Scale) and psychological distress (Depression Anxiety Stress Scales, 21 item). The majority (66%) of respondents reported moderate to high resilience. Physical disability impacted on coping, with greater CD-RISC 10 scores reported by individuals who were functionally independent in addition to those who experienced less medical co-morbidities. Significant correlations between resilience and psychological traits (self-esteem r=0.36, Pself-esteem and self-compassion. It follows that cognitive behavioural strategies with a focus on self-management may, in part, contribute to the process of resilience in this group. Further large-scale and longitudinal research will help to confirm these findings.

GPD program at COMPASS

2010-01-01

The study of exclusive reactions like Deeply Virtual Compton Scattering (DVCS) and Meson Production is one major part of the future COMPASS program1 in order to investigate nucleon structure through Generalised Parton Distributions (GPD). The high energy of the muon beam allows to measure the $x_{B}$-dependence of the $t$-slope of the pure DVCS cross section and to study nucleon tomography. The use of positive and negative polarised muon beams allows to determine the Beam Charge and Spin Difference of the DVCS cross sections to access the real part of the Compton form factor related to the dominant GPD H.

Instability timescale for the inclination instability in the solar system

Zderic, Alexander; Madigan, Ann-Marie; Fleisig, Jacob

2018-04-01

The gravitational influence of small bodies is often neglected in the study of solar system dynamics. However, this is not always an appropriate assumption. For example, mutual secular torques between low mass particles on eccentric orbits can result in a self-gravity instability (`inclination instability'; Madigan & McCourt 2016). During the instability, inclinations increase exponentially, eccentricities decrease (detachment), and orbits cluster in argument of perihelion. In the solar system, the orbits of the most distant objects show all three of these characteristics (high inclination: Volk & Malhotra (2017), detachment: Delsanti & Jewitt (2006), and argument of perihelion clustering: Trujillo & Sheppard (2014)). The inclination instability is a natural explanation for these phenomena.Unfortunately, full N-body simulations of the solar system are unfeasible (N ≈ O(1012)), and the behavior of the instability depends on N, prohibiting the direct application of lower N simulations. Here we present the instability timescale's functional dependence on N, allowing us to extrapolate our simulation results to that appropriate for the solar system. We show that ~5 MEarth of small icy bodies in the Sedna region is sufficient for the inclination instability to occur in the outer solar system.

Oncologist burnout and compassion fatigue: investigating time pressure at work as a predictor and the mediating role of work-family conflict.

Science.gov (United States)

Kleiner, Sibyl; Wallace, Jean E

Oncologists are at high risk of poor mental health. Prior research has focused on burnout, and has identified heavy workload as a key predictor. Compassion fatigue among physicians has generally received less attention, although medical specialties such as oncology may be especially at risk of compassion fatigue. We contribute to research by identifying predictors of both burnout and compassion fatigue among oncologists. In doing so, we distinguish between quantitative workload (e.g., work hours) and subjective work pressure, and test whether work-family conflict mediates the relationships between work pressure and burnout or compassion fatigue. In a cross-sectional study, oncologists from across Canada (n = 312) completed questionnaires assessing burnout, compassion fatigue, workload, time pressure at work, work-family conflict, and other personal, family, and occupational characteristics. Analyses use Ordinary Least Squares regression. Subjective time pressure at work is a key predictor of both burnout and compassion fatigue. Our results also show that work-family conflict fully mediates these relationships. Overall, the models explain more of the variation in burnout as compared to compassion fatigue. Our study highlights the need to consider oncologists' subjective time pressure, in addition to quantitative workload, in interventions to improve mental health. The findings also highlight a need to better understand additional predictors of compassion fatigue.

Structural design with high light absorption is the key challenge for thin film solar cells because of its poor absorption. In this paper, the light-trapping performance of silicon inclined nanohole arrays is systematically studied. The finite difference time domain method is used to calculate the optical absorption of different inclination angles in different periods and diameters. The results indicate that the inclined nanoholes with inclination angles between 5° and 45° demonstrate greater light-trapping ability than their counterparts of the vertical nanoholes, and they also show that by choosing the optimal parameters for the inclined nanoholes, a 31.2 mA/cm2 short circuit photocurrent density could be achieved, which is 10.25% higher than the best vertical nanohole system and 105.26% higher than bare silicon with a thickness of 2330 nm. The design principle proposed in this work gives a guideline for choosing reasonable parameters in the application of solar cells.

Experimental study on flow pattern transitions for inclined two-phase flow

Energy Technology Data Exchange (ETDEWEB)

Kwak, Nam Yee; Lee, Jae Young [Handong Univ., Pohang (Korea, Republic of); Kim, Man Woong [Korea Institute of Nuclear Safety, Daejeon (Korea, Republic of)

2007-07-01

In this paper, experimental data on flow pattern transition of inclination angles from 0-90 are presented. A test section is constructed 2 mm long and I.D 1inch using transparent material. The test section is supported by aluminum frame that can be placed with any arbitrary inclined angles. The air-water two-phase flow is observed at room temperature and atmospheric condition using both high speed camera and void impedance meter. The signal is sampled with sampling rate 1kHz and is analyzed under fully-developed condition. Based on experimental data, flow pattern maps are made for various inclination angles. As increasing the inclination angels from 0 to 90, the flow pattern transitions on the plane jg-jf are changed, such as stratified flow to plug flow or slug flow or plug flow to bubbly flow. The transition lines between pattern regimes are moved or sometimes disappeared due to its inclined angle.

Do neotropical migrant butterflies navigate using a solar compass?

Science.gov (United States)

Oliveira; Srygley; Dudley

1998-12-01

Many tropical butterfly species are well-known for their migratory behaviour. Although these insects can maintain a constant direction throughout the day, the physiological mechanisms of orientation are unknown. It has been argued that tropical migrant butterflies must use a time-compensated sun compass to accomplish their journey, but the crucial experimental manipulations to test this hypothesis have not been conducted. This study reports the results of clock-shift experiments performed with two species of migrating butterflies (Pieridae: Aphrissa statira and Phoebis argante) captured during flight across Lake Gatun, Panama. The observed constant flight bearing of natural controls suggests that these species are capable of performing time-compensated celestial navigation. Our clock-shift experiments suggest that a sun compass is involved. Individuals submitted to a 4 h advance shift took significantly different mean orientations on release compared with control butterflies. The direction of this difference was consistent with the use of a sun compass. The magnitude was approximately half the predicted value if the vanishing bearing of released butterflies was used as the variable to evaluate the effect of time-shifting and approximately three-quarters of that predicted if the estimated heading was the variable used. Mean vanishing bearings of control and experimental butterflies did not correspond to predicted values. This difference can be attributed largely to the combined effects of wind and handling.

2009-01-01

New Micromegas (Micro-mesh gaseous detectors) are being developed in view of the future physics projects planned by the COMPASS collaboration at CERN. Several major upgrades compared to present detectors are being studied: detectors standing five times higher luminosity with hadron beams, detection of beam particles (flux up to a few hundred of kHz/mm 2 , 10 times larger than for the present detectors) with pixelized read-out in the central part, light and integrated electronics, and improved robustness. Studies were done with the present detectors moved in the beam, and two first pixelized prototypes are being tested with muon and hadron beams in real conditions at COMPASS. We present here this new project and report on two series of tests, with old detectors moved into the beam and with pixelized prototypes operated in real data taking condition with both muon and hadron beams.

Self-compassion moderates the relationship between body mass index and both eating disorder pathology and body image flexibility.

Science.gov (United States)

Kelly, Allison C; Vimalakanthan, Kiruthiha; Miller, Kathryn E

2014-09-01

The current study examined whether self-compassion, the tendency to treat oneself kindly during distress and disappointments, would attenuate the positive relationship between body mass index (BMI) and eating disorder pathology, and the negative relationship between BMI and body image flexibility. One-hundred and fifty-three female undergraduate students completed measures of self-compassion, self-esteem, eating disorder pathology, and body image flexibility, which refers to one's acceptance of negative body image experiences. Controlling for self-esteem, hierarchical regressions revealed that self-compassion moderated the relationships between BMI and the criteria. Specifically, the positive relationship between BMI and eating disorder pathology and the negative relationship between BMI and body image flexibility were weaker the higher women's levels of self-compassion. Among young women, self-compassion may help to protect against the greater eating disturbances that coincide with a higher BMI, and may facilitate the positive body image experiences that tend to be lower the higher one's BMI.

Self-compassion and physical health: Exploring the roles of perceived stress and health-promoting behaviors

Directory of Open Access Journals (Sweden)

Kristin J Homan

2017-09-01

Full Text Available Growing evidence indicates that self-compassion is associated with better physical health, but the pathways that mediate this relationship are not well understood. This study tested a serial mediation model that linked self-compassion, perceived stress, health behaviors, and a comprehensive index of physical health. A sample of 176 individuals completed an online survey posted on Amazon’s Mechanical Turk. Self-compassion had an indirect effect on physical health via both mediators and through the sequential pathway, suggesting that taking a kind, accepting and mindful stance toward one’s flaws and failures may have benefits for reducing stress and promoting health behaviors.

Discordant timing between antennae disrupts sun compass orientation in migratory monarch butterflies

Science.gov (United States)

Guerra, Patrick A; Merlin, Christine; Gegear, Robert J; Reppert, Steven M

2014-01-01

To navigate during their long-distance migration, monarch butterflies (Danaus plexippus) use a time-compensated sun compass. The sun compass timing elements reside in light-entrained circadian clocks in the antennae. Here we show that either antenna is sufficient for proper time compensation. However, migrants with either antenna painted black (to block light entrainment) and the other painted clear (to permit light entrainment) display disoriented group flight. Remarkably, when the black-painted antenna is removed, re-flown migrants with a single, clear-painted antenna exhibit proper orientation behaviour. Molecular correlates of clock function reveal that period and timeless expression is highly rhythmic in brains and clear-painted antennae, while rhythmic clock gene expression is disrupted in black-painted antennae. Our work shows that clock outputs from each antenna are processed and integrated together in the monarch time-compensated sun compass circuit. This dual timing system is a novel example of the regulation of a brain-driven behaviour by paired organs. PMID:22805565

The COMPASS-Like Complex Promotes Flowering and Panicle Branching in Rice1[OPEN

Wang, Shiliang; Jiang, Haiyang; Cheng, Beijiu

2018-01-01

Flowering time (heading date) and panicle branch number are important agronomic traits that determine yield in rice (Oryza sativa). The activation of flowering requires histone methylation, but the roles of trimethylation of Lys 4 of histone 3 (H3K4me3) in modulating heading date and panicle development are unclear. Here, we showed that the COMPASS-like complex promotes flowering and panicle branching. The rice (Oryza sativa) WD40 protein OsWDR5a interacts with the TRITHORAX-like protein OsTrx1/SET domain group protein 723 (SDG723) to form the core components of the COMPASS-like complex. Plants in which OsWDR5a or OsTrx1 expression was decreased by RNA interference produced fewer secondary branches and less grain and exhibited a delayed heading date under long-day and short-day conditions, whereas loss of OsWDR5a function resulted in embryo lethality. OsWDR5a binds to Early heading date 1 to regulate its H3K4me3 and expression levels. Together, our results show that the COMPASS-like complex promotes flowering and panicle development and suggest that modulation of H3K4me3 levels by the COMPASS-like complex is critical for rice development.

Sky compass orientation in desert locusts – evidence from field and laboratory studies

Directory of Open Access Journals (Sweden)

Uwe eHomberg

2015-12-01

Full Text Available Locusts are long-range migratory insects. At high population density, immature animals form marching hopper bands while adults take off and form huge swarms of millions of animals. At low population densities animals are solitarious, but likewise migrate, mostly during the night. Numerous studies aimed at predicting locust infestations showed that migrations both as hopper bands and as adults are largely downwind following seasonal shifts of the tropical convergence zone taking the animals to areas of rainfall. Only a few studies provided evidence for active orientation mechanisms, including the involvement of a sun compass. This scarcity of evidence stands in contrast to recent neurobiological data showing sophisticated neuronal adaptations suited for sky compass navigation. These include a special dorsal eye region with photoreceptors suited to analyze the polarization pattern of the sky and a system of topographically arranged sky compass neurons in the central complex of the brain. Laboratory experiments, moreover, demonstrated polarotaxis in tethered flying animals. The discrepancy of these findings call for more rigorous field studies on active orientation mechanisms in locusts. It remains to be shown how locusts use their internal sky compass during mass migrations and what role it plays to guide solitarious locusts in their natural habitat.

Magnetic compass orientation in the European eel.

Directory of Open Access Journals (Sweden)

Caroline M F Durif

Full Text Available European eel migrate from freshwater or coastal habitats throughout Europe to their spawning grounds in the Sargasso Sea. However, their route (~ 6000 km and orientation mechanisms are unknown. Several attempts have been made to prove the existence of magnetoreception in Anguilla sp., but none of these studies have demonstrated magnetic compass orientation in earth-strength magnetic field intensities. We tested eels in four altered magnetic field conditions where magnetic North was set at geographic North, South, East, or West. Eels oriented in a manner that was related to the tank in which they were housed before the test. At lower temperature (under 12°C, their orientation relative to magnetic North corresponded to the direction of their displacement from the holding tank. At higher temperatures (12-17°C, eels showed bimodal orientation along an axis perpendicular to the axis of their displacement. These temperature-related shifts in orientation may be linked to the changes in behavior that occur between the warm season (during which eels are foraging and the colder fall and winter (during which eels undertake their migrations. These observations support the conclusion that 1. eels have a magnetic compass, and 2. they use this sense to orient in a direction that they have registered moments before they are displaced. The adaptive advantage of having a magnetic compass and learning the direction in which they have been displaced becomes clear when set in the context of the eel's seaward migration. For example, if their migration is halted or blocked, as it is the case when environmental conditions become unfavorable or when they encounter a barrier, eels would be able to resume their movements along their old bearing when conditions become favorable again or when they pass by the barrier.

Held, Philip; Owens, Gina P

2015-06-01

The present pilot study examined the effects of a 4-week-long self-administered self-compassion training on trauma-related guilt and compared it to a stress inoculation control group. A total of 47 homeless male veterans who were living in transitional housing facilities volunteered to participate in this study. Participants were randomly assigned to either a self-compassion (N = 13) or a stress inoculation (N = 14) group and were asked to complete pre-, mid-, and postintervention assessments measuring changes in self-compassion, trauma-related guilt, and posttraumatic stress disorder severity. Participants in both interventions reported increased levels of self-compassion and equal reductions in trauma-related guilt. No other significant changes were noted. The results from this pilot study provide preliminary evidence for the use of self-compassion and stress inoculation trainings as effective interventions for trauma-related guilt. The findings also suggest that self-administered trainings in the form of workbooks may be a viable, cost-effective form of intervention for disadvantaged populations, such as homeless veterans in transitional housing, who may lack resources or access to professionals or paraprofessionals. The effects of both self-compassion training and stress inoculation training on the study variables and directions for future research on self-compassion and trauma-related guilt are discussed. © 2015 Wiley Periodicals, Inc.

Compassion, Citizenship and Education in South Africa: An Opportunity for Transformation?

Science.gov (United States)

Waghid, Yusef

2004-11-01

This study explores how citizenship education in South Africa is guided by liberal and communitarian concepts of citizenship. Its contention is that citizenship education, as it has evolved through policy discourses on "Values, Education and Democracy", is heavily influenced by liberal and communitarian concepts of citizenship. Nonetheless, the liberal-communitarian concept of citizenship education is not sufficient on its own to bring about educational transformation in institutions. Instead, citizenship education initiatives in South Africa need to promote a sense of compassion, motivating learners to take seriously the suffering of others. It is argued that such compassion represents a precondition of genuine educational transformation.

COMPASS is a new experimental toroidal assembly of compact design and with a wide range of physics objectives. It is required to operate either as a Tokamak or as a Reversed Field Pinch with interchangeable circular and dee-section vacuum vessels. The Toroidal field is produced by 16 rectangular coils of 4 turns with tapered conductors on the inside which nest together to form a vault to resist the centering forces. The coils are designed to produce a maximum field on axis of 2.1T which requires a current of 91 kA per turn. Two central solenoids and five pairs of coils symmetrically positioned above and below the machine equator provide the poloidal field. Both coil systems are supported form a mechanical support structure which surrounds the machine. This is primarily designed to resist out-of-plane forces on the TF coils but also acts as the base support for the PF coils and vacuum vessels. An illustration of the COMPASS Load Assembly is given and shows the D-shaped vacuum vessel, the major components and the various field windings

Self-compassion and psychological distress in parents of young people and adults with intellectual and developmental disabilities.

2018-05-01

Parenting an individual with intellectual and developmental disabilities (IDD) can be challenging, particularly during adulthood. It is important to better understand ways of supporting families as individuals with IDD age. Self-compassion is a potential internal coping resource for parents, and is strongly linked to positive mental health outcomes, though research has yet to examine it in parents of adults with IDD. The current study examines the association between self-compassion and measures of well-being for 56 parents of adults with IDD. Greater self-compassion was related to lower levels of stress and depression, even after accounting for other known stressors, such as economic disadvantage, having a child with an Autism Spectrum Disorder diagnosis, and high parent burden. Self-compassion may offer resiliency against these parenting challenges. © 2017 John Wiley & Sons Ltd.

Loners, Groupies, and Long-term Eccentricity (and Inclination) Behavior: Insights from Secular Theory

Science.gov (United States)

Van Laerhoven, Christa L.

2015-05-01

Considering the secular dynamics of multi-planet systems provides substantial insight into the interactions between planets in those systems. Secular interactions are those that don't involve knowing where a planet is along its orbit, and they dominate when planets are not involved in mean motion resonances. These interactions exchange angular momentum among the planets, evolving their eccentricities and inclinations. To second order in the planets' eccentricities and inclinations, the eccentricity and inclination perturbations are decoupled. Given the right variable choice, the relevant differential equations are linear and thus the eccentricity and inclination behaviors can be described as a sum of eigenmodes. Since the underlying structure of the secular eigenmodes can be calculated using only the planets' masses and semi-major axes, one can elucidate the eccentricity and inclination behavior of planets in exoplanet systems even without knowing the planets' current eccentricities and inclinations. I have calculated both the eccentricity and inclination secular eigenmodes for the population of known multi-planet systems whose planets have well determined masses and periods. Using this catalog of secular character, I will discuss the prevalence of dynamically grouped planets ('groupies') versus dynamically uncoupled planets ('loners') and how this relates to the exoplanets' long-term eccentricity and inclination behavior. I will also touch on the distribution of the secular eigenfreqiencies.

To be kind or not to be kind: The moderating role of self-compassion in the relationship between general resourcefulness and academic self-regulation.

Science.gov (United States)

Martin, Rebecca D; Kennett, Deborah J

2017-11-22

We investigated whether the relationship between students' general resourcefulness and academic self-regulation changes as a function of self-compassion. A predominantly female sample of 196 undergraduates completed inventories assessing these and other measures. The significant moderating effect of self-compassion revealed that the positive relationship between general resourcefulness and academic self-regulation was stronger for participants scoring low in self-compassion than high in self-compassion. For those low in self-compassion, scoring low in general resourcefulness was associated with the lowest academic self-regulation, whereas scoring high in general resourcefulness was associated with the greatest academic self-regulation. The positive relationship between general and academic self-regulation was attenuated for participants high in self-compassion, with predicted scores for academic self-regulation falling in between the two values described for the low self-compassion function. Implications of the findings are discussed, including the potential value of incorporating self-compassion training alongside programs aimed at increasing general resourcefulness and academic self-regulation.

Stomaching rejection: Self-compassion and self-esteem moderate the impact of daily social rejection on restrictive eating behaviours among college women.

Science.gov (United States)

Beekman, Janine B; Stock, Michelle L; Howe, George W

2017-11-01

The present study examined whether having high self-esteem or a self-compassionate perspective help mitigate the impact of daily social rejection on negative affect and restrictive eating behaviours. Following a baseline survey assessing self-esteem and self-compassion, 121 college women completed online daily diaries for one week. Negative affect and restrictive eating behaviours. On days when women reported more rejection, they also reported higher restrictive eating behaviours and greater negative affect. Effects were moderated by self-esteem and self-compassion, such that the lower participants were in self-esteem or self-compassion, the stronger the positive relation between rejection and negative affect and restrictive eating. However, only the common humanity/isolation dimension of self-compassion significantly moderated daily effects of rejection when controlling for self-esteem. Mediated moderation results reveal different mechanisms by which self-esteem and self-compassion buffer against rejections' effects on affect and restrictive eating. Self-compassion and self-esteem influence the complex impact that social rejection has on affect and restrictive eating. More than other dimensions of self-compassion or self-esteem, remembering one's common humanity can result in a healthier response to social rejection.

Which Physicians' Behaviors on Death Pronouncement Affect Family-Perceived Physician Compassion? A Randomized, Scripted, Video-Vignette Study.

2018-02-01

Although the death of a loved one is a devastating family event, little is known about which behaviors positively affect families' perceptions on death pronouncements. The objective of this study was to evaluate the effect of a compassionate death pronouncement on participant-perceived physician compassion, trust in physicians, and emotions. In this randomized, video-vignette study, 92 people (≥50 years) in Tokyo metropolitan area viewed two videos of death pronouncements by an on-call physician with or without compassion-enhanced behaviors, including five components: waiting until the families calm themselves down, explaining that the physician has received a sign-out about information of the patient's condition, performing examination respectfully, ascertaining the time of death with a wristwatch (vs. smartphone), and reassuring the families that the patient did not experience pain. Main outcomes were physician compassion score, trust in physician, and emotions. After viewing the video with compassion-enhanced behaviors compared with the video without them, participants assigned significantly lower compassion scores (reflecting higher physician compassion) (mean 26.2 vs. 36.4, F = 33.1, P vs. 3.00, F = 39.7, P vs. 3.78, F = 18.0, P sadness (3.42 vs. 3.85, F = 11.8, P = 0.001), fear (1.93 vs. 2.55, F = 15.8, P vs. 3.71, F = 19.4, P < 0.001). To convey compassion on death pronouncement, we recommend that physicians initiate prompt examination, explain that the physician has received a sign-out, perform examination respectfully, ascertain the time of death with a wristwatch, and reassure the families that the patient did not experience pain.

Light Scalar Mesons in Central Production at COMPASS

2016-01-01

COMPASS is a fixed-target experiment at the CERN SPS that studies the spectrum of light-quark hadrons. In 2009, it collected a large dataset using a $190\\,$GeV$/c$ positive hadron beam impinging on a liquid-hydrogen target in order to measure the central exclusive production of light scalar mesons. One of the goals is the search for so-called glueballs, which are hypothetical meson-like objects without valence-quark content. We study the decay of neutral resonances by selecting centrally produced pion pairs from the COMPASS dataset. The angular distributions of the two pseudoscalar mesons are decomposed in terms of partial waves, where particular attention is paid to the inherent mathematical ambiguities. The large dataset allows us to perform a detailed analysis in bins of the two squared four-momentum transfers carried by the exchange particles in the reaction. Possible parameterisations of the mass dependence of the partial-wave amplitudes in terms of resonances are also discussed.

Highlights: • A mathematical model was presented to analyze the performance of inclined still. • The effect of air speed, water masses, film thickness and velocity was studied. • Productivity for the Model 3 was higher than conventional still by 57.2%. • The performance was strongly affected by water film thickness and velocity. • Model 3 gave the highest performance while Model 1 gave the lowest performance. - Abstract: In the present work, theoretical study of the performance evaluation of a continuous water flow inclined solar still desalination system is performed. Three models are studied for inclined solar still desalination system with and without water close loop. The effects of the water mass, water film thickness, water film velocity and air wind velocity on the performance of the three models are studied. The results show that the inclined solar still with a makeup water is superior in productivity (57.2% improvement) compared with a conventional basin-type solar still. Also, the application of inclined solar still with open water loop is recommended when combined with other still desalination system due to high water temperature output. The inclined solar still with a makeup (Model 3) gives the highest performance while Model 1 gives the lowest performance. Finally, the water film thickness, and velocity as well as wind velocity plays important roles in improving the still productivity and efficiency

Short-term compassion training increases prosocial behavior in a newly developed prosocial game

OpenAIRE

Leiberg, S.; Klimecki, O.; Singer, T.

2011-01-01

Compassion has been suggested to be a strong motivator for prosocial behavior. While research has demonstrated that compassion training has positive effects on mood and health, we do not know whether it also leads to increases in prosocial behavior. We addressed this question in two experiments. In Experiment 1, we introduce a new prosocial game, the Zurich Prosocial Game (ZPG), which allows for repeated, ecologically valid assessment of prosocial behavior and is sensitive to the influence of...

The present investigation was aimed at testing whether the lizard sky polarization compass is time compensated. For this purpose, ruin lizards, Podarcis sicula, were both trained and tested for orientation inside a Morris water maze under clear skies with the sun not in view. During training, lizards showed a striking bimodal orientation along the training axis, demonstrating their capability of determining the symmetry plane of the sky polarization pattern and thus the use of polarization information in orientation. After reaching criteria, lizards were kept 7 days in a 6-h fast clock-shift treatment and then released with the sun not in view. Six-hour clock-shifted lizards showed a bimodal distribution of directional choices, which was oriented perpendicularly to the training axis, as it was expected on the basis of the clock-shift. The results show that the only celestial diurnal compass mechanism that does not need a direct vision of the sun disk (i.e., the sky polarization compass) is a time-compensated compass.

Although evaluation of biochemical analytes in blood is common in veterinary practice, studies assessing the global quality of veterinary in-clinic and reference laboratory testing have not been reported. The aim of this study was to assess the quality of biochemical testing in veterinary laboratories using results obtained from analyses of 3 levels of assayed quality control materials over 5 days. Quality was assessed by comparison of calculated total error with quality requirements, determination of sigma metrics, use of a quality goal index to determine factors contributing to poor performance, and agreement between in-clinic and reference laboratory mean results. The suitability of in-clinic and reference laboratory instruments for statistical quality control was determined using adaptations from the computerized program, EZRules3. Reference laboratories were able to achieve desirable quality requirements more frequently than in-clinic laboratories. Across all 3 materials, > 50% of in-clinic analyzers achieved a sigma metric ≥ 6.0 for measurement of 2 analytes, whereas > 50% of reference laboratory analyzers achieved a sigma metric ≥ 6.0 for measurement of 6 analytes. Expanded uncertainty of measurement and ± total allowable error resulted in the highest mean percentages of analytes demonstrating agreement between in-clinic and reference laboratories. Owing to marked variation in bias and coefficient of variation between analyzers of the same and different types, the percentages of analytes suitable for statistical quality control varied widely. These findings reflect the current state-of-the-art with regard to in-clinic and reference laboratory analyzer performance and provide a baseline for future evaluations of the quality of veterinary laboratory testing. © 2012 American Society for Veterinary Clinical Pathology.

A model is presented for thermal convection in an inclined layer of porous material when the medium has a bidispersive structure. Thus, there are the usual macropores which are full of a fluid, but there are also a system of micropores full of the same fluid. The model we employ is a modification of the one proposed by Nield & Kuznetsov (2006 Int. J. Heat Mass Transf. 49, 3068–3074. (doi:10.1016/j.ijheatmasstransfer.2006.02.008)), although we consider a single temperature field only. PMID:27616934

Spontaneous expression of magnetic compass orientation in an epigeic rodent: the bank vole, Clethrionomys glareolus

Magnetoreception has been convincingly demonstrated in only a few mammalian species. Among rodents, magnetic compass orientation has been documented in four species of subterranean mole rats and two epigeic (i.e. active above ground) species—the Siberian hamster and the C57BL/6J mouse. The mole rats use the magnetic field azimuth to determine compass heading; their directional preference is spontaneous and unimodal, and their magnetic compass is magnetite-mediated. By contrast, the primary component of orientation response is learned in the hamster and the mouse, but both species also exhibit a weak spontaneous bimodal preference in the natural magnetic field. To determine whether the magnetic compass of wild epigeic rodents features the same functional properties as that of laboratory rodents, we investigated magnetic compass orientation in the bank vole Clethrionomys glareolus (Cricetidae, Rodentia). The voles exhibited a robust spontaneous bimodal directional preference, i.e. built nests and slept preferentially along the north-south axis, and deflected their directional preference according to a shift in the direction of magnetic north, clearly indicating that they were deriving directional information from the magnetic field. Thus, bimodal, axially symmetrical directional choice seems to be a common feature shared by epigeic rodents. However, spontaneous directional preference in the bank vole appeared to be more pronounced than that reported in the hamster and the mouse. These findings suggest that bank voles are well suited for future studies investigating the adaptive significance and mechanisms of magnetic orientation in epigeic rodents.

Diffractive dissociation reactions at the COMPASS experiment, CERN, provide access to the meson resonance spectrum. During a pilot run in 2004, using a pion beam on a lead target, a competitive number of {pi}{sup -} {pi}{sup -} {pi}{sup +} final state events with masses below 2.5 GeV/c{sup 2} were recorded. After COMPASS had finished its muon program in 2007, it used in 2008 again a pion beam, but now a liquid hydrogen target, and gathered during several weeks a unique high statistics. A full partial wave analysis of the 2004 data has been performed, with the focus on the kinematic range of a large momentum transfer (0.1 GeV{sup 2}/c{sup 2} {<=} t' {<=} 1.0 GeV{sup 2}/c{sup 2}). In addition first results of the adjacent analysis with 2008 data are presented.

Bonnoit, C.; Lanuza, J.; Lindner, A.; Clément, E.

2008-07-01

We investigate the flow behavior of dense granular suspensions, by the use of an inclined plane. The suspensions are prepared at high packing fractions and consist of spherical non-Brownian particles density matched with the suspending fluid. On the inclined plane, we perform a systematic study of the surface velocity as a function of the layer thickness for various flow rates and tilt angles. We perform measurements on a classical rheometer (parallel-plate rheometer) that is shown to be in good agreement with existing models, up to a volume fraction of 50%. Comparing these results, we show that the flow on an inclined plane can, up to a volume fraction of 50%, indeed be described by a purely viscous model in agreement with the results from classical rheometry.

Power deposition on misaligned edges in COMPASS

Directory of Open Access Journals (Sweden)

R. Dejarnac

2017-08-01

Full Text Available If the decision is made not to apply a toroidal chamfer to tungsten monoblocks at ITER divertor vertical targets, exposed leading edges will arise as a result of assembly tolerances between adjacent plasma-facing components. Then, the advantage of glancing magnetic field angles for spreading plasma heat flux on top surfaces is lost at the misaligned edges with an interaction occurring at near normal incidence, which can drive melting for the expected inter-ELM heat fluxes. A dedicated experiment has been performed on the COMPASS tokamak to thoroughly study power deposition on misaligned edges using inner-wall limited discharges on a special graphite tile presenting gaps and leading edges directly viewed by a high resolution infra-red camera. The parallel power flux deducted from the unperturbed measurement far from the gap is fully consistent with the observed temperature increase at the leading edge, respecting the power balance. All the power flowing into the gap is deposited at the leading edge and no mitigation factor is required to explain the thermal response. Particle-in-cell simulations show that the ion Larmor smoothing effect is weak and that the power deposition on misaligned edges is well described by the optical approximation because of an electron dominated regime associated with non-ambipolar parallel current flow.

Two-Dimensional Computational Flow Analysis and Frictional Characteristics Model for Red Blood Cell under Inclined Centrifuge Microscopy

Science.gov (United States)

Funamoto, Kenichi; Hayase, Toshiyuki; Shirai, Atsushi

Simplified two-dimensional flow analysis is performed in order to simulate frictional characteristics measurement of red blood cells moving on a glass plate in a medium with an inclined centrifuge microscope. Computation under various conditions reveals the influences of parameters on lift, drag, and moment acting on a red blood cell. Among these forces, lift appears only when the cell is longitudinally asymmetric. By considering the balance of forces, the frictional characteristics of the red blood cell are modeled as the sum of Coulomb friction and viscous drag. The model describes the possibility that the red blood cell deforms to expand in the front side in response to the inclined centrifugal force. When velocity exceeds some critical value, the lift overcomes the normal centrifugal force component, and the thickness of the plasma layer between the cell and the glass plate increases from the initial value of the plasma protein thickness.

It is important to determine the bucco-lingual inclination of implants on radiographs before the implant surgery. The purpose of this study was to compare the buccolingual inclination in alveolar bone and the tooth with dental cone beam CT and to prepare the standard for the buccolingual inclination of implant. Axial, panoramic, and buccolingually sectioned images of 80 implant cases with stent including straight marker using CB Mercuray TM (Hitachi, Japan) were evaluated. The comparison of the buccolingual inclination of remained alveolar bone with the tooth and the marker on buccolingually sectioned views was performed statistically. The average buccolingual inclination of remained alveolar bone and tooth was 82.8 ± 4.6 .deg. C and 85.8 ± 4.7 .deg. C (p 0.05, r=0.12) at the 2nd premolar area in upper jaw. The average buccolingual inclination of remained alveolar bone and tooth was 81.3 ± 8.3 .deg. C and 87.5 ± 6.3 .deg. C (p>0.05, r=0.85) at the lower 2nd premolar area and 94.3 ± 6.6 .deg. C and 93.3 ± 7.2 .deg. C respectively (p>0.05, r=0.91) at the 1st molar area in lower jaw. The inclinations of markers were very different from those of remained bone at the most of areas except the upper 2nd premolar area (r=0.79). We recommend dental CBCT analysis for determining the buccolingual inclination of dental implant, because of significant difference, in average, between the buccolingual inclination of remained alveolar bone and tooth.

Highlights: • Li-BES detection system on the COMPASS tokamak is optimized observation system with high temporal resolution. • High sensitivity to low level light fluctuations. • Optics and detectors with electronics are placed in thermally stabilized compact box. • Fast deflection system allows us to measure background corrected electron density profiles on microsecond time-scale. - Abstract: A new Li beam emission spectroscopy (Li-BES) diagnostic system with a ∼ cm spatial resolution, and with beam energy ranging from 10 keV up to 120 keV and a 18 channel Avalanche photo diode (APD) detector system sampled at 2 MHz has been recently installed and tested on the COMPASS tokamak. This diagnostic allows to reconstruct density profile based on directly measured light profiles, and to follow turbulent behaviour of the edge plasma. The paper reports technical capabilities of this new system designed for fine spatio-temporal measurements of plasma electron density. Focusing on turbulence-induced fluctuation measurements, we demonstrate how physically relevant information can be extracted using the COMPASS Li-BES system.

Walking is a popular form of exercise and is associated with many health benefits; however, frontal-plane knee joint loading brought about by a large internal knee-abduction moment and cyclic loading could lead to cartilage degeneration over time. Therefore, knee joint mechanics during an alternative walking exercise needs to be analyzed. The purpose of this study was to examine the lower-extremity joint mechanics in the frontal and sagittal planes during incline walking. Fifteen healthy males walked on a treadmill at five gradients (0%, 5%, 10%, 15%, and 20%) at 1.34m/s, and lower-extremity joint mechanics in the frontal and sagittal planes were quantified. The peak internal knee-abduction moment significantly decreased from the level walking condition at all gradients except 5%. Also, a negative relationship between the internal knee-abduction moment and the treadmill gradient was found to exist in 10% increments (0-10%, 5-15%, and 10-20%). The decrease in the internal knee-abduction moment during incline walking could have positive effects on knee joint health such as potentially reducing cartilage degeneration of the knee joint, reducing pain, and decreasing the rate of development of medial tibiofemoral osteoarthritis. This would be beneficial for a knee surgery patient, obese persons, and older adults who are using incline walking for rehabilitation and exercise protocols. Findings from the current study can provide guidance for the development of rehabilitation and exercise prescriptions incorporating incline walking. Copyright © 2014 Elsevier B.V.

COMPASS results on the transverse spin asymmetry in hadron-pair production in SIDIS

CERN Document Server

Braun, Christopher

2015-01-01

The parton distribution function h q 1 ( x ) of a transversely polarized quark q inside a transversely po- larized nucleon, is chiral-odd and therefore not accessible in inclusive deep-inelastic scattering. It can however be observed in semi-inclusive deep-inelastic scattering (SIDIS) in combination with another chiral-odd func- tion, for instance the dihadron interference fragmentation function (DiFF) H / q 1 . The 160 GeV = c polarized muon beam of CERN’s M2 beamline allows COMPASS to investigate transverse spin e ects using polarized solid- state targets. In this contribution an overview of COMPASS results for the azimuthal asymmetry in identified dihadron production is given. Pions and kaons were identified by a RICH detector. Recently, the full set of this asymmetry from the COMPASS data on the deuteron and the proton target became available. All data, includ- ing early data sets, were analyzed using the same methods and requirements. The results are compared to model predictions and HERMES data. Also ...

To report findings from a qualitative study of key stakeholders' perspectives on 'compassion' in the health care context. To present the 'Framework for Compassionate Interpersonal Relations'. Although many research articles, health policies and health care strategies identify compassion as an underpinning value and key component of health care quality, identifying a unified definition of compassion is challenging. For Higher Education Institutions implementing 'values-based' recruitment processes, a clearer understanding of this core concept is vital. Exploratory, qualitative design. Academic staff, health care students, clinicians and service users (n = 45), participated in nine focus groups where they were asked to define compassion in the context of health care. Data were transcribed verbatim and analysed using thematic analysis. Four overarching themes were drawn from the data. The first theme centred on the participants' definitions of compassion, while the second identified compassionate behaviours. The third theme related to the barriers and threats to compassionate practice and the fourth, focused on ways to support compassion in practice. Participants believed that the health care staff should be 'consistently compassionate', and were emphatic that compassion should not be substituted with a 'care without engagement' approach. The findings concur with other research, which identifies the link between compassion and empathy and the importance of establishing meaningful connections with others. While participants in this study recognised the pressures of health care work and accepted that the expectation of 'consistent compassion' was not necessarily realistic, it was still seen as an important goal. Participants held clear expectations regarding practitioners' communication skills and used these as a proxy for compassionate practice. The 'Framework for Compassionate Inter-personal Relations' may be used to promote reflection on the implementation of

Mind-body practices that intentionally generate positive emotion could improve health professionals' well-being and compassion. However, the feasibility and impact of clinician training in these practices is unknown. Data were analyzed from 3 online modules offered to health professionals: (a) Gratitude, (b) Positive Word, and (c) Loving-kindness/Compassion meditation. Pairedttests were used to assess pre- to posttraining changes in gratitude (Gratitude Questionnaire), well-being (World Health Organization Well-Being Index), self-compassion (Neff's Self-Compassion Scale), and confidence in providing compassionate care (Confidence in Providing Calm, Compassionate Care Scale). The 177 enrollees included diverse practitioners (nurses, physicians, social workers, and others). Training was associated with statistically significant improvements in gratitude (38.3 ± 4.6 to 39.5 ± 3.3), well-being (16.4 ± 4.0 to 17.9 ± 4.2), self-compassion (39.5 ± 8.1 to 43.1 ± 7.6), and confidence in providing compassionate care (73.3 ± 16.4 to 80.9 ± 13.8;Pgratitude, well-being, self-compassion, and confidence in providing compassionate care. © The Author(s) 2016.

Full Text Available Exclusive ω meson production is studied by the COMPASS Collaboration using the CERN 160 GeV/c muon beam and a transversely polarised proton target. Single-spin and double-spin asymmetries are measured, some of which are sensitive to the Generalised Parton Distributions E that are related to quark orbital angular momenta. The results, which are sensitive also to the pion-pole contribution to the production mechanism, are compared to the predictions of a phenomenological model.

Measuring Magnetic Declination With Compass, GPS and Virtual Globes

Science.gov (United States)

O'Brien, W. P.

2006-12-01

Using virtual globe (VG) imagery to determine geographic bearing and a compass to determine magnetic bearing yielded acceptable experimental magnetic declination values for large linear physical features at 13 sites in the western continental United States. The geographic bearing of each feature was determined from measurements involving the latitude/longitude coordinate system associated with the VG image (from World Wind or Google Earth). The corresponding magnetic bearing was measured on the ground at the feature with a hand-bearing compass calibrated in 1-degree subdivisions. A sequence of GPS trackpoints, recorded while traveling along the feature either in an automobile or on foot, unambiguously identified the pertinent portion of the feature (a straight segment of a road, for example) when plotted on the VG image. For each physical feature located on a VG image, its geographic bearing was determined directly using on-screen measurement tools available with the VG program or by hand using ruler/protractor methods with printed copies of the VG image. An independent (no use of VG) geographic bearing was also extracted from the slope of a straight-line fit to a latitude/longitude plot of each feature's GPS coordinates, a value that was the same (to within the inherent uncertainty of the data) as the VG-determined bearing, thus validating this procedure for finding geographic bearings. Differences between the VG bearings and the magnetic bearings yielded experimental magnetic declination values within one degree (8 within 0.5 degree) of expected values. From the point of view of physics and geophysics pedagogy, this project affords students a simple magnetism/geodesy field experiment requiring only a good compass and a GPS receiver with memory and a data port. The novel and straightforward data analysis with VG software yields reliable experimental values for an important abstract geophysical quantity, magnetic declination. Just as the compass has long provided

Interplay between geometry and temperature for inclined Casimir plates

International Nuclear Information System (INIS)

Weber, Alexej; Gies, Holger

2009-01-01

We provide further evidence for the nontrivial interplay between geometry and temperature in the Casimir effect. We investigate the temperature dependence of the Casimir force between an inclined semi-infinite plate above an infinite plate in D dimensions using the worldline formalism. Whereas the high-temperature behavior is always found to be linear in T in accordance with dimensional-reduction arguments, different power-law behaviors at small temperatures emerge. Unlike the case of infinite parallel plates, which shows the well-known T D behavior of the force, we find a T D-1 behavior for inclined plates, and a ∼T D-0.3 behavior for the edge effect in the limit where the plates become parallel. The strongest temperature dependence ∼T D-2 occurs for the Casimir torque of inclined plates. Numerical as well as analytical worldline results are presented.

Granular flow down a flexible inclined plane

Directory of Open Access Journals (Sweden)

Sonar Prasad

2017-01-01

Full Text Available Discrete and continuous systems are commonly studied individually, but seldom together. Indeed, granular flows are typically studied through flows over a rigid base. Here, we investigate the behaviour of granular flows over an inclined, flexible base. The flexible base is modeled as a rigid platform mounted on springs and has one degree of freedom. The base vibrations are introduced by the flow. We simulate such flows through a discrete element method and compare with experiments. We find that a flexible base increased the upper limit of the inclination up to which a steady flow is possible by at least 3 degrees. This stabilized zone may have important implications in applications such as conveyor belts and chutes.

The metabolic cost of walking on an incline in the Peacock (Pavo cristatus).

Wilkinson, Holly; Thavarajah, Nathan; Codd, Jonathan

2015-01-01

Altering speed and moving on a gradient can affect an animal's posture and gait, which in turn can change the energetic requirements of terrestrial locomotion. Here, the energetic and kinematic effects of locomoting on an incline were investigated in the Indian peacock, Pavo cristatus. The mass-specific metabolic rate of the Indian peacock was elevated on an incline, but this change was not dependent on the angle ascended and the cost of lifting remained similar between the two inclines (+5 and +7°). Interestingly, the Indian peacock had the highest efficiency when compared to any other previously studied avian biped, despite the presence of a large train. Duty factors were higher for birds moving on an incline, but there was no difference between +5 and +7°. Our results highlight the importance of investigating kinematic responses during energetic studies, as these may enable explanation of what is driving the underlying metabolic differences when moving on inclines. Further investigations are required to elucidate the underlying mechanical processes occurring during incline movement.

A Siemens programmable logic controller (PLC) powered by an uninterruptable source keeps the cryogenic system safe and stable during the long beam periods by controlling valves and interlocks. This safety feature protects the dilution refrigerator against potential damages in case of power failure.

Tooth Wear Inclination in Great Ape Molars.

Primate dietary diversity is reflected in their dental morphology, with differences in size and shape of teeth. In particular, the tooth wear angle can provide insight into a species' ability to break down certain foods. To examine dietary and masticatory information, digitized polygon models of dental casts provide a basis for quantitative analysis of wear associated with tooth attrition. In this study, we analyze and compare the wear patterns of Pongo pygmaeus, Gorilla gorillagorilla and Pan troglodytes schweinfurthii lower molars, focusing on the degree of inclination of specific wear facets. The variation in wear angles appears to be indicative of jaw movements and the specific stresses imposed on food during mastication, reflecting thus the ecology of these species. Orangutans exhibit flatter wear angles, more typical of a diet consisting of hard and brittle foods, while gorillas show a wear pattern with a high degree of inclination, reflecting thus their more leafy diet. Chimpanzees, on the other hand, show intermediate inclinations, a pattern that could be related to their highly variable diet. This method is demonstrated to be a powerful tool for better understanding the relationship between food, mastication and tooth wear processes in living primates, and can be potentially used to reconstruct the diet of fossil species. © 2017 S.

Miyazaki, Daisuke; Eto, Takuma; Nishimura, Yasuhiro; Matsushita, Kenji

2003-05-01

A volumetric display system based on three-dimensional (3-D) scanning that uses an inclined two-dimensional (2-D) image is described. In the volumetric display system a 2-D display unit is placed obliquely in an imaging system into which a rotating mirror is inserted. When the mirror is rotated, the inclined 2-D image is moved laterally. A locus of the moving image can be observed by persistence of vision as a result of the high-speed rotation of the mirror. Inclined cross-sectional images of an object are displayed on the display unit in accordance with the position of the image plane to observe a 3-D image of the object by persistence of vision. Three-dimensional images formed by this display system satisfy all the criteria for stereoscopic vision. We constructed the volumetric display systems using a galvanometer mirror and a vector-scan display unit. In addition, we constructed a real-time 3-D measurement system based on a light section method. Measured 3-D images can be reconstructed in the 3-D display system in real time.

2013-04-01

Studies have consistently highlighted the deleterious impact of burnout and compassion fatigue on professional nurses' well-being and willingness to remain in the profession. Yet, as to what extent these noxious conditions are suffered among nursing students is still unclear. In this study 436 undergraduate nursing students completed surveys assessing their experiences of emotional exhaustion, depersonalization, lack of personal accomplishment, burnout, secondary traumatic stress, and compassion satisfaction (factors of burnout and compassion fatigue). There were no significant differences found between 3rd and 4th year students' reports of detrimental conditions and those of the 1st or 2nd year students. Furthermore, 4th year students reported significantly higher levels of personal accomplishment compared to 1st and 2nd year students. Semi-structured in-depth interviews with 3rd and 4th year students revealed that their clinical exposure during these years (especially during the 4th year) may enhance their other-orientation as well as promote role actualization, which may serve as protective features. Students did, however, express concern regarding an inevitable onset of burnout at some point during their professional careers. It is suggested that a key to understanding the onset and experience of burnout and compassion fatigue among nurses is to continue to examine the transition from student to professional nurse and the cultural atmosphere of nursing education compared to professional practice.

Measurement of transverse momentum dependent asymmetries with COMPASS experimental at CERN

2007-07-01

The COMPASS experiment, which started running at the European Council for Nuclear Research, CERN, in Geneva in 2001, is currently investigating in a wide ranging programme the spin structure of the nucleon through deep-inelastic scattering (DIS). The experiment uses a polarized muon beam and a polarized deuterium target, which together allow access to all terms of the polarized DIS cross-section. Two of the most important functions which COMPASS is designed to full are a precision measurement of the gluon polarization {delta}G and the investigation of the transverse spin effects, specially extracting the transverse polarized quark distribution functions {delta}{sub T}q. In Semi-Inclusive DIS of polarized leptons on a transversely polarized target, eight azimuthal modulations appear in the cross-section. Within the QCD parton model, four azimuthal asymmetries can be interpreted at leading order, two of them being the Collins and Sivers asymmetries. The other two leading twist asymmetries are related to different transverse momentum dependent quark distribution functions. There are four additional asymmetries which can be interpreted as twist-three contributions. This thesis describes the analysis with the data taken with transverse spin configuration during the COMPASS beam-time 2002-2004, resulting in the extraction of the eight Transverse Momentum Dependent (TMD) asymmetries.

Inhomogeneous ensembles of radical pairs in chemical compasses

Procopio, Maria; Ritz, Thorsten

2016-11-01

The biophysical basis for the ability of animals to detect the geomagnetic field and to use it for finding directions remains a mystery of sensory biology. One much debated hypothesis suggests that an ensemble of specialized light-induced radical pair reactions can provide the primary signal for a magnetic compass sensor. The question arises what features of such a radical pair ensemble could be optimized by evolution so as to improve the detection of the direction of weak magnetic fields. Here, we focus on the overlooked aspect of the noise arising from inhomogeneity of copies of biomolecules in a realistic biological environment. Such inhomogeneity leads to variations of the radical pair parameters, thereby deteriorating the signal arising from an ensemble and providing a source of noise. We investigate the effect of variations in hyperfine interactions between different copies of simple radical pairs on the directional response of a compass system. We find that the choice of radical pair parameters greatly influences how strongly the directional response of an ensemble is affected by inhomogeneity.

New measurements of transverse spin asymmetries at COMPASS

Sozzi, F

2012-01-01

The study of transverse momentum effects and transverse spin structure of the nucleon is an important part of the scientific program of COMPASS, a fixed target experiment at the CERN SPS. The transverse effects are investigated via semi inclusive DIS reactions with a 160 GeV /c muon beam impinging on transversely polarised targets. The hadrons produced in the reactions are detected in a wide momentum and angular range by a two-stage spectrometer. A deuterium target has been used in the first part of COMPASS data taking from 2002 to 2004, while a proton target has been used in 2007 and 2010. Here we present the recent results obtained from the 2010 data on different channels, involving the azimuthal distribution of single hadrons and the azimuthal dependence of the plane cont aining hadron pairs. The results confirm the published results of the 2007 data taking with an improved statistical significance; the measured azimuthal asymmetries are clearly non zero, at variance with those measured on a deuterium targ...

Highlights: • Li-beam diagnostic system on the COMPASS tokamak is an improved and compact system to allow testing of Atomic Beam Probe. • The possibility to measure background corrected density profiles on the few microseconds time scale. • First Li-beam diagnostic system with recirculating neutralizer. • The system includes the redesigned ion source with longer lifetime. - Abstract: An improved lithium beam based beam emission spectroscopy system – installed on COMPASS tokamak – is described. The beam energy enhanced up to 120 keV for Atomic Beam Probe measurement. The size of the ion source is doubled, using a newly developed thermionic heater instead of the conventionally used heating (tungsten or molybdenum) filament. The neutralizer is also improved. It produces the same sodium vapor in a cell but minimize the loss condensing the vapor on a cold surface which is led back (in fluid state) into the sodium oven. This way we call it recirculating neutralizer. The observation system consists of a CCD camera and an avalanche photodiode array.

To describe the hadronization process of quarks into hadrons in deep inelastic scattering knowledge of parton distribution functions and fragmentation functions is necessary. Parton distribution functions can be extracted from inclusive deep inelastic scattering. To extract fragmentation functions from data taken by the COMPASS experiment final state hadrons are analyzed in addition to the incoming and scattered muon. I give a status report of K{sub s}{sup 0} multiplicities from data taken in 2006 by the COMPASS experiment which can be used to parameterize K{sub s}{sup 0} fragmentation functions.

Self-Compassion Scale (SCS): Psychometric Properties of The French Translation and Its Relations with Psychological Well-Being, Affect and Depression.

Science.gov (United States)

Kotsou, Ilios; Leys, Christophe

2016-01-01

Over the past few years, the topic of self-compassion has attracted increasing attention from both scientific and clinical fields. The Self-Compassion Scale (SCS) was created to specifically capture this way of being kind and understanding towards oneself in moments of turmoil. In this article, we present a French adaptation of the SCS. We first explore the psychometric properties of this adaptation and then investigate its relation to psychological well-being. As in the original version of the SCS, the French adaptation has a strong 6-factor structure but a weaker hierarchical second order structure. However the bi-factor model yields a good omega index suggesting the relevance of a single score accounting for self-compassion. Moreover, there was a relation between the SCS and classical outcomes such as a positive relation with psychological well-being and negative relation with depressive symptoms. We then hypothesized that self-compassion would have a moderating role on the relation between affect and depression. This hypothesis was confirmed: expressing negative affect is correlated with depressive symptoms; however, being kind with oneself lowers depressive symptoms even when expressing negative affect. In conclusion, this research presents a valid self-compassion measure for French-speaking researchers and clinicians and outlines the need for further research on the concept of self-compassion.

Fluorescence intensity dependence on the propagation plane inclination

Fernandez, J.E.; Rubio, Marcelo; Sanchez, H.J.

1987-01-01

A Monte Carlo simulation of the primary and secondary X-ray fluorescent emission from an homogeneous and infinite thickness sample, irradiated under different inclination of the propagation plane, is carried out. An agreement with the predictions based on Sherman equations depending on the inclination angle α was found. The invariance of the primary fluorescence with respect to α and the decrease until evanescence of the secondary fluorescence for a α → π/2 are confirmed. A discussion about the physical basis of this dependence is carried out. Similar results are expected for tertiary fluorescence. (Author) [es

Full Text Available Entrepreneurship has been the fundamental topics of discussion among the politicians, economists, and academics. Business creation is especially critical in developing countries to stimulate economic growth. The present study attempts to examine entrepreneurial inclination among students who are a potential source of entrepreneurs. The fi ndings of the present research study indicate that majority of our business students are not entrepreneurial-inclined. They do not seem to possess strong entrepreneurial characteristics and entrepreneurial skills, and they are not keen in starting a new business. The roles of higher institutes of education and the government in promoting entrepreneurship are discussed.

Natural Frequencies and Mode Shapes of Statically Deformed Inclined Risers

KAUST Repository

Alfosail, Feras

2016-10-15

We investigate numerically the linear vibrations of inclined risers using the Galerkin approach. The riser is modeled as an Euler-Bernoulli beam accounting for the nonlinear mid-plane stretching and self-weight. After solving for the initial deflection of the riser due to self-weight, we use a Galerkin expansion employing 15 axially loaded beam mode shapes to solve the eigenvalue problem of the riser around the static equilibrium configuration. This yields the riser natural frequencies and corresponding exact mode shapes for various values of inclination angles and tension. The obtained results are validated against a boundary-layer analytical solution and are found to be in good agreement. This constitutes a basis to study the nonlinear forced vibrations of inclined risers.

Revealing strong bias in common measures of galaxy properties using new inclination-independent structures

Science.gov (United States)

Devour, Brian M.; Bell, Eric F.

2017-06-01

Accurate measurement of galaxy structures is a prerequisite for quantitative investigation of galaxy properties or evolution. Yet, the impact of galaxy inclination and dust on commonly used metrics of galaxy structure is poorly quantified. We use infrared data sets to select inclination-independent samples of disc and flattened elliptical galaxies. These samples show strong variation in Sérsic index, concentration and half-light radii with inclination. We develop novel inclination-independent galaxy structures by collapsing the light distribution in the near-infrared on to the major axis, yielding inclination-independent 'linear' measures of size and concentration. With these new metrics we select a sample of Milky Way analogue galaxies with similar stellar masses, star formation rates, sizes and concentrations. Optical luminosities, light distributions and spectral properties are all found to vary strongly with inclination: When inclining to edge-on, r-band luminosities dim by >1 magnitude, sizes decrease by a factor of 2, 'dust-corrected' estimates of star formation rate drop threefold, metallicities decrease by 0.1 dex and edge-on galaxies are half as likely to be classified as star forming. These systematic effects should be accounted for in analyses of galaxy properties.

2012-01-01

Compassion is critical for complementary and conventional care, but little is known about its direct physiologic effects. This study tested the feasibility of delivering two lengths of time (10 and 20 minutes) and two strategies (tactile and nontactile) for a practitioner to nonverbally communicate compassion to subjects who were blind to the interventions. Healthy volunteers were informed that we were testing the effects of time and touch on the autonomic nervous system. Each subject underwent five sequential study periods in one study session: (1) warm-up; (2) control-with the practitioner while both read neutral material; (3) rest; (4) intervention-with practitioner meditating on loving-kindness toward the subject; and (5) rest. Subjects were randomized to receive one of four interventions: (1) 10 minutes tactile; (2) 20 minutes tactile; (3) 10 minutes nontactile; or (4) 20 minutes nontactile. During all interventions, the practitioner meditated on loving-kindness toward the subject. For tactile interventions, the practitioner touched subjects on arms, legs, and hands; for nontactile interventions, the practitioner pretended to read. Subjects' autonomic activity, including heart rate, was measured continuously. Subjects completed visual analog scales for well-being, including relaxation and peacefulness, at warm-up; postcontrol; immediately postintervention; and after the postintervention rest and were asked about what they and the practitioner had done during each study period. The 20 subjects' mean age was 24.3 ± 4 years; 16 were women. The practitioner maintained a meditative state during all interventions as reflected in lower respiratory rate, and subjects remained blind to the practitioner's meditative activity. Overall, interventions significantly decreased heart rate (P < .01), and although other changes did not reach statistical significance, they were in the expected direction, with generally greater effects for the tactile than nontactile strategies

Inclined solar chimney for power production

Highlights: → Solar energy harnessing using inclined face of high mountains as solar chimney. → Solar chimneys with structural stability, ease of construction and lower cost. → Mathematical model developed, using complete (mechanical and thermal) energy balance. → Can harness wind power also, as wind velocities at mountain top add to power output. → Air temperature and velocity increase, as air rises in inclined chimney. - Abstract: The present concept of solar chimney is a tall vertical chimney constructed at the center of a large area, which is the collector. This creates questions about stability and economic viability of the chimney and also demands elaborate engineering techniques for constructing a tall chimney. We suggest geometry of 'Inclined Solar Chimney' (ISC), which is constructed along the face of a high rising mountain, on which maximum solar insolation is incident throughout the year. The chimney and the collector get merged here. This makes the structure stable, cost effective and easy for construction. A mathematical model has been developed considering the total energy balance. It predicts the temperature and velocity and kinetic power of the emerging air draft for some chosen values of other parameters. The model also shows the proportion in which absorbed solar energy is divided into different forms, and hence predicts the dependence of kinetic of emerging air draft upon dimensions of the chimney and properties of materials used. Further, it is shown that external winds enhance the kinetic power of the emerging air. Thus ISC can also harness the wind energy, available at the top of the mountain.

Full Text Available This study empirically investigated the performance of four configurations of inclined solar water desalination (ISWD system for parameters such as daily production, efficiency, system cost, and distilled water production cost. The empirical findings show that in terms of daily productivity improved inclined solar water desalination (IISWD performed best with 6.41 kg/m2/day while improved inclined solar water desalination with wire mesh (IISWDWM produced the least with 3.0 kg/m2/day. In terms of cost price of the systems, the control system inclined solar water desalination (ISWD is the cheapest while IISWDWM is the most expensive system. Distilled water cost price ranges from 0.059 TL/kg, for IISWDW, to 0.134 TL/kg, for IISWDWM system. All the systems are economically and technically feasible as a solar desalination system for potable water in northern Cyprus. Potable water from vendors/hawkers ranges from 0.2 to 0.3 TL/kg.

Hydrodynamics of single- and two-phase flow in inclined rod arrays

Ebeling-Koning, D.B.; Todreas, N.E.

1983-09-01

Required inputs for thermal-hydraulic codes are constitutive relations for fluid-solid flow resistance, in single-phase flow, and interfacial momentum exchange (relative phase motion), in two-phase flow. An inclined rod array air-water experiment was constructed to study the hydrodynamics of multidimensional porous medium flow in rod arrays. Velocities, pressures, and bubble distributions were measured in square rod arrays of P/d = 1.5, at 0, 30, 45, and 90 degree inclinations to the vertical flow direction. Constitutive models for single-phase flow resistance are reviewed, new comprehensive models developed, and an assessment with previously published and new data made. The principle of superimposing one-dimensional correlations proves successful for turbulent single-phase inclined flow. For bubbly two-phase incline flow a new flow separation phenomena was observed and modeled. A two-region liquid velocity model is developed to explain the experimentally observed phenomena. Fundamental data for bubbles rising in rod arrays were also taken

Looking down: the influence of contempt and compassion on emergent leadership categorizations.

Science.gov (United States)

Melwani, Shimul; Mueller, Jennifer S; Overbeck, Jennifer R

2012-11-01

By integrating the literatures on implicit leadership and the social functions of discrete emotions, we develop and test a theoretical model of emotion expression and leadership categorizations. Specifically, we examine the influence of 2 socio-comparative emotions-compassion and contempt-on assessments of leadership made both in 1st impression contexts and over time. To demonstrate both internal and external validity, Studies 1a and 1b provide laboratory and field evidence to show that expressing the discrete emotions of contempt and compassion positively relates to perceptions that an individual is a leader. Study 2 tests the mechanism explaining these associations. Specifically, we show that in a leadership emergence context, contempt and compassion both positively relate to perceptions that the expresser is a leader because each provides cues matching the implicit theory that leaders have higher intelligence. Our findings add to a growing body of literature focused on identifying the processes through which leaders emerge in groups, showing that emotions are an important input to this process. We discuss the implications of our findings and how they might guide future research efforts. (c) 2012 APA, all rights reserved.

Numerical Analysis of Aerodynamic Characteristics of the Finned Surfaces with Cross-inclined Fins

Directory of Open Access Journals (Sweden)

Lagutin A. E.

2016-12-01

Full Text Available This paper presents results of numerical research and analyses air-side hydraulic performance of tube bundles with cross inclined fins. The numerical simulation of the fin-tube heat exchanger was performed using the Comsol Femlab software. The results of modeling show the influence of fin inclination angle and tube pitch on hydraulic characteristics of finned surfaces. A series of numerical tests were carried out for tube bundles with different inclination angles (γ =900, 850, 650, 60, the fin pitch u=4 mm. The results indicate that tube bundles with cross inclined fins can significantly enhance the average integral value of the air flow rate in channel between fins in comparison with conventional straight fins. Aerodynamic processes on both sides of modificated channel between inclined fins were analyzed. The verification procedures for received results of numerical modeling with experimental data were performed.

A pilot study on the effects and feasibility of compassion-focused expressive writing in Day Hospice patients.

Science.gov (United States)

Imrie, Susan; Troop, Nicholas A

2012-06-01

Research has found that writing about stress can confer physical and psychological health benefits on participants and that adopting a self-compassionate stance may have additional benefits. This pilot study evaluated a self-compassionate expressive writing intervention in a Day Hospice setting. Thirteen patients with life-limiting illnesses wrote on two occasions about recent stressful experiences. Half also received a self-compassion instruction for their writing. Outcome measures were taken at baseline and one week after the second writing session, and text analysis was used to identify changes in the types of words used, reflecting changes in psychological processes. Patients given the self-compassion instruction increased in their self-soothing and self-esteem in contrast to patients in the stress-only condition. Happiness broadly increased in both groups although reported levels of stress generally increased in patients given the self-compassion instruction but decreased in patients in the stress-only condition. Those given the self-compassion instruction also increased in their use of causal reasoning words across the two writing sessions compared with those in the stress-only condition. Expressive writing appears to be beneficial in patients at a hospice and was viewed as valuable by participants. The inclusion of a self-compassion instruction may have additional benefits and a discussion of the feasibility of implementing expressive writing sessions in a Day Hospice is offered.

Histone H3 lysine 4 (H3K4) methylation is catalyzed by the highly evolutionarily conserved multiprotein complex known as Set1/COMPASS or MLL/COMPASS-like complexes from yeast to human, respectively. Here we have reconstituted fully functional yeast Set1/COMPASS and human MLL/COMPASS-like complex in vitro and have identified the minimum subunit composition required for histone H3K4 methylation. These subunits include the methyltransferase C-terminal SET domain of Set1/MLL, Cps60/Ash2L, Cps50/RbBP5, Cps30/WDR5, and Cps25/Dpy30, which are all common components of the COMPASS family from yeast to human. Three-dimensional (3D) cryo-EM reconstructions of the core yeast complex, combined with immunolabeling and two-dimensional (2D) EM analysis of the individual subcomplexes reveal a Y-shaped architecture with Cps50 and Cps30 localizing on the top two adjacent lobes and Cps60-Cps25 forming the base at the bottom. EM analysis of the human complex reveals a striking similarity to its yeast counterpart, suggesting a common subunit organization. The SET domain of Set1 is located at the juncture of Cps50, Cps30, and the Cps60-Cps25 module, lining the walls of a central channel that may act as the platform for catalysis and regulative processing of various degrees of H3K4 methylation. This structural arrangement suggested that COMPASS family members function as exo-methylases, which we have confirmed by in vitro and in vivo studies.

COMPASS is an indigenously developed Chinese global navigation satellite system and will share many features in common with GPS (Global Positioning System). Since the ultra-tight GPS/INS (Inertial Navigation System) integration shows its advantage over independent GPS receivers in many scenarios, the federated ultra-tight COMPASS/INS integration has been investigated in this paper, particularly, by proposing a simplified prefilter model. Compared with a traditional prefilter model, the state space of this simplified system contains only carrier phase, carrier frequency and carrier frequency rate tracking errors. A two-quadrant arctangent discriminator output is used as a measurement. Since the code tracking error related parameters were excluded from the state space of traditional prefilter models, the code/carrier divergence would destroy the carrier tracking process, and therefore an adaptive Kalman filter algorithm tuning process noise covariance matrix based on state correction sequence was incorporated to compensate for the divergence. The federated ultra-tight COMPASS/INS integration was implemented with a hardware COMPASS intermediate frequency (IF), and INS's accelerometers and gyroscopes signal sampling system. Field and simulation test results showed almost similar tracking and navigation performances for both the traditional prefilter model and the proposed system; however, the latter largely decreased the computational load.

Palliative medicine is a rewarding field, but providers encounter patient trauma on a routine basis. Compassion fatigue, marked by burnout, secondary traumatic stress, and low satisfaction may result. However, professionals differ markedly in how they respond to patient trauma. The objective of the current study was to determine whether personality traits of neuroticism and agreeableness relate to aspects of compassion fatigue, after accounting for time spent working in the field. Sixty-six palliative medicine physicians, nurses, social workers, and chaplains completed validated measures of personality traits, compassion fatigue, and work background. Providers who had worked longer reported higher levels of satisfaction and lower levels of burnout. Neuroticism demonstrated strong significant associations with secondary traumatic stress and burnout ( Ps accounting for years spent working in the field. Personality traits of neuroticism and agreeableness may convey risk and resilience, respectively, for palliative care professionals. More research is needed to determine if assessing personality traits can help identify providers at risk for adverse reactions to patient trauma.

The COMPASS-II experiment is a fixed target experiment situated at CERN. A tertiary myon beam from the SPS scattered of protons from a liquid hydrogen target is used to measure Deeply Virtual Compton Scattering (DVCS) and Hard Exclusive Meson Production (HEMP). These processes offer a unique way to determine Generalized Parton Distributions, which are related to the total angular momentum of quarks, antiquarks and gluons in the nucleon by Ji's Sum Rule. One of the major parts of the COMPASS-II upgrade is the CAMERA detector. CAMERA is a proton recoil detector surrounding the COMPASS-II liquid hydrogen target. Its purpose is to measure the recoiled target proton in DVCS and HEMP reactions and viz to act as a veto to ensure the exclusivity of the measurement. The talk gives an outline of the detector and its readout electronics. It is focused on the commissioning and performance of the CAMERA detector and gives a brief insight into the ongoing DVCS analysis.

The COMPASS experiment uses ring imaging Cherenkov (RICH) counters to identify particles produced in high-energy muon collisions, to better understand the spin structure of the nucleon. Charged particles moving faster than the speed of light in the medium through which they are travelling emit a cone of Cherenkov radiation in the direction of their motion. The light in this cone is reflected from these mirrors onto a photo detector so that the size of the cone can be measured, which gives the energy of the particle.

This study examines the implications of assembling and operating Space Station Freedom at a 51.6 degree inclination orbit utilizing an enhanced lift Space Shuttle. Freedom assembly is currently baselined at a 220 nautical mile high, 28.5 degree inclination orbit. Some of the reasons for increasing the orbital inclination are (1) increased ground coverage for Earth observations, (2) greater accessibility from Russian and other international launch sites, and (3) increased number of Assured Crew Return Vehicle (ACRV) landing sites. Previous studies have looked at assembling Freedom at a higher inclination using both medium and heavy lift expendable launch vehicles (such as Shuttle-C and Energia). The study assumes that the shuttle is used exclusively for delivering the station to orbit and that it can gain additional payload capability from design changes such as a lighter external tank that somewhat offsets the performance decrease that occurs when the shuttle is launched to a 51.6 degree inclination orbit.

On the other hand it is known that depressive symptoms may also overlap the physical symptoms of cancer and cancer treatment, which may interfere in their detection and appropriate treatment approach.   Objectives: The aim of the current study was to explore the relationship between psychological adjustment to lung cancer, self-compassion, social support and emotional negative states in patients with lung cancer.   Method: Fifty-five patients diagnosed with lung cancer (38 men and 17 women with ages ranging from 44 to 87 years old participated in the study. A set of self-report instruments was used: the Mini Mental Adjustment to Cancer Scale (MiniMac, the Self-compassion Scale (SCS; Neff, 2003, the Social Support Satisfaction Scale (SSSS and the Depression, Anxiety and Stress Scale (DASS-21.   Results: Significant correlations were found between psychological adjustment, psychopathology, emotion regulation strategies (self-compassion, and social support. The predictive models for psychological adjustment and stress related symptomatology include self-compassion and social support as significant predictive variables. Regarding the predictive model for depressive symptomatology, mindfulness seems to be the only significant predictor.   Conclusions: Our findings suggest that these patients may benefit, in their therapeutic approach, from the development of this kind of strategies (new ways of relating themselves with their emotional experiences and quality of their social networks in order to promote a better psychological adjustment to their clinical condition.

Full Text Available Background and Objective: Buccolingual inclination of teeth is an essential factor in establishing good occlusion. The objective of this study was to evaluate the buccolingual inclination of molar teeth in different vertical skeletal patterns by using computed tomography scans. Materials and Methods: Coronal section of the jaws obtained from computed tomograms were used to measure the buccolingual inclination of the long axis of the molars relative to their skeletal base. Forty male adult individuals with class I dental occlusion were selected. They were classified as short (Group 1, average (Group II, and long faced (Group III as per their skeletal patterns measured by GoGn-SN, FH-MP, Y-axis and facial height index in cephalograms. Statistical Analysis: ANOVA and Tukey HSD tests were applied to calculate if there were any significant differences in the mean molar inclination between the groups. Pearson′s coefficients of correlation were calculated between the facial parameters and tooth inclination. Results: The differences in the mean molar inclination between the short, average, and long faced groups is significant for mandibular 1 st and 2 nd molars and maxillary 2 nd molars. Conclusion: Variations in mean molar inclination values are observed between short, average, and long faced groups.

The interfacial shear stress is experimentally investigated for co-current air-water stratified flow in inclined rectangular channels having a length of 1854mm, width of 120 mm and height of 40mm at almost atmospheric pressure. Experiments are carried out in several inclinations from 0 deg up to 10 deg. The local film thickness and the wave height are measured at three locations, i.e., L/H = 8,23, and 40. According to the inclination angle, the experimental data are categorized into two groups; nearly horizontal data group (0 deg {<=} {theta} {<=} 0.7 deg), and inclined channel data group (0.7 deg {<=} {theta} {<=} 10 deg ). Experimental observations for nearly horizontal data group show that the flow is not fully developed due to the water level gradient and the hydraulic jump within the channel. For the inclined channel data group, a dimensionless wave height, {Delta}h/h, is empirically correlated in terms of Re{sub G} and h/H. A modified root-mean-square wave height is proposed to consider the effects of the interfacial and wave propagation velocities. It is found that an equivalent roughness has a linear relationship with the modified root-mean-square wave height and its relationship is independent of the inclination. 10 refs., 6 figs., 1 tab.

An investigation into the multifaceted relationship between gratitude, empathy, and compassion

Directory of Open Access Journals (Sweden)

Grace Y. Kim

2018-01-01

Full Text Available The virtues of gratitude, empathy, and compassion are associated with various psychological and relational benefits. Past research suggests that gratitude and empathy are correlated and that compassion is in fact derived from empathy. However, limited research exists concerning the direct relationship between gratitude and compassionate love (i.e., a more enduring form of compassion. This study examined the relationship between the two constructs, with empathy as a potential mediator in this relationship. Two hundred undergraduate students from a religiously affiliated university were recruited and completed an online, multi-section questionnaire that includes measures of gratitude, empathy, and compassionate love. Statistical analyses revealed a significant partial mediation effect, with gratitude being both directly and indirectly (via empathy associated with compassionate love. In other words, higher levels of gratitude produced greater compassionate love through increased feelings of empathy. Further analyses indicated that among the three types of empathy explored (cognitive empathy, emotional contagion, and emotional disconnection, cognitive empathy best mediated the relationship between gratitude and compassionate love. These findings have important implications in both a clinical and research context, including the utilization of gratitude and empathy interventions to increase protection against clinician burnout and improve client health and well-being. Future research is warranted in further exploring the relationship among these variables utilizing more objective forms of measurement.

Predictors and moderators of biopsychological social stress responses following brief self-compassion meditation training.

Arch, Joanna J; Landy, Lauren N; Brown, Kirk Warren

2016-07-01

Arch et al. (2014) demonstrated that brief self-compassion meditation training (SCT) dampened sympathetic (salivary alpha-amylase) and subjective anxiety responses to the Trier Social Stress Test (TSST), relative to attention and no-instruction control conditions. The present study examined baseline predictors and moderators of these SCT intervention effects. Baseline characteristics included two stress vulnerability traits (social anxiety and rumination) and two potential resiliency traits (non-attachment and self-compassion). We investigated how these traits moderated the effects of SCT on response to the TSST, relative to the control conditions. We also tested how these individual differences predicted TSST responses across conditions in order to uncover characteristics that confer increased vulnerability and resiliency to social stressors. Trait non-attachment, rumination (for sympathetic TSST response only), and social anxiety (for subjective TSST response only) interacted with training condition to moderate TSST responses such that following SCT, lower attachment and lower social anxiety predicted lower TSST stress responses, relative to those scoring higher on these traits. In contrast, trait self-compassion neither moderated nor predicted responses to the TSST. Thus, although SCT had robust effects on buffering stress across individuals with varying levels of trait self-compassion, other psychological traits enhanced or dampened the effect of SCT on TSST responses. These findings support the importance of examining the role of relevant baseline psychological traits to predict sympathetic and subjective responses to social evaluative threat, particularly in the context of resiliency training.

Formation of Close-in Super-Earths by Giant Impacts: Effects of Initial Eccentricities and Inclinations of Protoplanets

2017-07-01

Recent observations have revealed the eccentricity and inclination distributions of close-in super-Earths. These distributions have the potential to constrain their formation processes. In the in situ formation scenario, the eccentricities and inclinations of planets are determined by gravitational scattering and collisions between protoplanets on the giant impact stage. We investigate the effect of the initial eccentricities and inclinations of protoplanets on the formation of close-in super-Earths. We perform N -body simulations of protoplanets in gas-free disks, changing the initial eccentricities and inclinations systematically. We find that while the eccentricities of protoplanets are well relaxed through their evolution, the inclinations are not. When the initial inclinations are small, they are not generally pumped up since scattering is less effective and collisions occur immediately after orbital crossing. On the other hand, when the initial inclinations are large, they tend to be kept large since collisional damping is less effective. Not only the resultant inclinations of planets, but also their number, eccentricities, angular momentum deficit, and orbital separations are affected by the initial inclinations of protoplanets.

Complex network analysis in inclined oil–water two-phase flow

International Nuclear Information System (INIS)

Zhong-Ke, Gao; Ning-De, Jin

2009-01-01

Complex networks have established themselves in recent years as being particularly suitable and flexible for representing and modelling many complex natural and artificial systems. Oil–water two-phase flow is one of the most complex systems. In this paper, we use complex networks to study the inclined oil–water two-phase flow. Two different complex network construction methods are proposed to build two types of networks, i.e. the flow pattern complex network (FPCN) and fluid dynamic complex network (FDCN). Through detecting the community structure of FPCN by the community-detection algorithm based on K-means clustering, useful and interesting results are found which can be used for identifying three inclined oil–water flow patterns. To investigate the dynamic characteristics of the inclined oil–water two-phase flow, we construct 48 FDCNs under different flow conditions, and find that the power-law exponent and the network information entropy, which are sensitive to the flow pattern transition, can both characterize the nonlinear dynamics of the inclined oil–water two-phase flow. In this paper, from a new perspective, we not only introduce a complex network theory into the study of the oil–water two-phase flow but also indicate that the complex network may be a powerful tool for exploring nonlinear time series in practice.

The Effects of Various Running Inclines on Three-Segment Foot Mechanics and Plantar Fascia Strain

Directory of Open Access Journals (Sweden)

Sinclair Jonathan

2014-12-01

Full Text Available Purpose. There has yet to be a combined analysis of three-dimensional multi-segment foot kinematics and plantar fascia strain in running gait at various degrees of inclination. The aim of the current study was therefore to investigate the above during treadmill running at different inclines (0°, 5°, 10° and 15°. Methods. Twelve male participants ran at 4.0 m · s-1 in the four different inclinations. Three-dimensional kinematics of the foot segments and plantar fascia strain were quantified for each incline and contrasted using one-way repeated measures ANOVA. Results and conclusions. The results showed that plantar fascia strain increased significantly as a function of running incline. Given the projected association between plantar fascia strain and the aetiology of injury, inclined running may be associated with a greater incidence of injury to the plantar fascia.

Objective: To test the null hypothesis that there is no effect of esthetic perception of smiling profile in three different facial types by a change in the maxillary incisor inclination and position. Materials and Methods: A smiling profile photograph with Class I skeletal and dental pattern, normal profile were taken in each of the three facial types dolichofacial, mesofacial, and brachyfacial. Based on the original digital image, 15 smiling profiles in each of the facial types were created using the FACAD software by altering the labiolingual inclination and anteroposterior position of the maxillary incisors. These photographs were rated on a visual analog scale by three panels of examiners consisting of orthodontists, dentists, and nonprofessionals with twenty members in each group. The responses were assessed by analysis of variance (ANOVA) test followed by post hoc Scheffe. Results: Significant differences (P esthetics. The result of the ANOVA showed differences among the three groups for certain facial profiles. Conclusion: The hypothesis was rejected. The esthetic perception of labiolingual inclination and anteroposterior of maxillary incisors differ in different facial types, and this may effect in formulating treatment plans for different facial types.

Design and Calibration of a Novel Bio-Inspired Pixelated Polarized Light Compass

Directory of Open Access Journals (Sweden)

Guoliang Han

2017-11-01

Full Text Available Animals, such as Savannah sparrows and North American monarch butterflies, are able to obtain compass information from skylight polarization patterns to help them navigate effectively and robustly. Inspired by excellent navigation ability of animals, this paper proposes a novel image-based polarized light compass, which has the advantages of having a small size and being light weight. Firstly, the polarized light compass, which is composed of a Charge Coupled Device (CCD camera, a pixelated polarizer array and a wide-angle lens, is introduced. Secondly, the measurement method of a skylight polarization pattern and the orientation method based on a single scattering Rayleigh model are presented. Thirdly, the error model of the sensor, mainly including the response error of CCD pixels and the installation error of the pixelated polarizer, is established. A calibration method based on iterative least squares estimation is proposed. In the outdoor environment, the skylight polarization pattern can be measured in real time by our sensor. The orientation accuracy of the sensor increases with the decrease of the solar elevation angle, and the standard deviation of orientation error is 0 . 15 ∘ at sunset. Results of outdoor experiments show that the proposed polarization navigation sensor can be used for outdoor autonomous navigation.

CERN

2014-01-01

The COMPASS experiment at CERN prepares a new measurement on the nucleon structure via Drell-Yan reactions using a transversely polarized ammonia target and a π− beam. This first-ever polarized Drell-Yan measurement will provide the insight into the transverse momentum depen- dent parton distribution functions such as the Sivers and Boer-Mulders functions, complementary to what is measured in the semi-inclusive deep-inelastic scattering process. The important features and status of this project are introduced.

Beyond Compassion: Replacing a Blame Culture With Proper Emotional Support and Management; Comment on “Why and How Is Compassion Necessary to Provide Good Quality Healthcare?”

Directory of Open Access Journals (Sweden)

Yiannis Gabriel

2015-09-01

Full Text Available The absence of compassion, argues the author, is not the cause of healthcare failures but rather a symptom of deeper systemic failures. The clinical encounter arouses strong emotions of anxiety, fear, and anger in patients which are often projected onto the clinicians. Attempts to protect clinicians through various bureaucratic devices and depersonalization of the patient, constitute as Menzies noted in her classic work, social defences, aimed at containing the anxieties of clinicians but ending up in reinforcing these anxieties. Instead of placing additional burdens on clinicians by bureaucratizing and benchmarking compassion, the author argues that proper emotional management and support is a precondition for a healthcare system that offers humane and effective treatment to patients and a humane working environment for those who work in it.

Constraining the inclination of the Low-Mass X-ray Binary Cen X-4

Hammerstein, Erica K.; Cackett, Edward M.; Reynolds, Mark T.; Miller, Jon M.

2018-05-01

We present the results of ellipsoidal light curve modeling of the low mass X-ray binary Cen X-4 in order to constrain the inclination of the system and mass of the neutron star. Near-IR photometric monitoring was performed in May 2008 over a period of three nights at Magellan using PANIC. We obtain J, H and K lightcurves of Cen X-4 using differential photometry. An ellipsoidal modeling code was used to fit the phase folded light curves. The lightcurve fit which makes the least assumptions about the properties of the binary system yields an inclination of 34.9^{+4.9}_{-3.6} degrees (1σ), which is consistent with previous determinations of the system's inclination but with improved statistical uncertainties. When combined with the mass function and mass ratio, this inclination yields a neutron star mass of 1.51^{+0.40}_{-0.55} M⊙. This model allows accretion disk parameters to be free in the fitting process. Fits that do not allow for an accretion disk component in the near-IR flux gives a systematically lower inclination between approximately 33 and 34 degrees, leading to a higher mass neutron star between approximately 1.7 M⊙ and 1.8 M⊙. We discuss the implications of other assumptions made during the modeling process as well as numerous free parameters and their effects on the resulting inclination.

A measurement of the muon number in showers using inclined events detected at the Pierre Auger Observatory

Directory of Open Access Journals (Sweden)

Rodriguez G.

2013-06-01

Full Text Available The average muon content of measured showers with zenith angles between 62∘ and 80∘ detected at the Pierre Auger Observatory is obtained as a function of shower energy using a reconstruction method specifically designed for inclined showers and the hybrid character of the detector. The reconstruction of inclined showers relies on a comparison between the measured signals at ground and reference patterns at ground level from which an overall normalization factor is obtained. Since inclined showers are dominated by muons this factor gives the relative muon size. It can be calibrated using a subsample of showers simultaneously recorded with the fluorescence detector (FD and the surface detector (SD which provides an independent calorimetric measurement of the energy. The muon size obtained for each shower becomes a measurement of the relative number of muons with respect to the reference distributions. The precision of the measurement is assessed using simulated events which are reconstructed using exactly the same procedure. We compare the relative number of muons versus energy as obtained to simulations. Proton simulations with QGSJETII show a factor of 2.13 ± 0.04(stat ± 0.11(sys at 1019eV without significant variations in the energy range explored between 4 × 1018eV to 7 × 1019eV. We find that none of the current shower models, neither for proton nor for iron primaries, are able to predict as many muons as are observed.

Full Text Available Child abuse is behavior in which child faces physical, sexual, negligence and emotional abuses. This study’s aimed to investigate relationship between childhood abuse and self-compassion with stress-coping strategies among women. Statistical population included all of married women in Tehran. The sample contains 182 participants who were selected by convenience sampling method entertainment centers, shopping centers, health centers and cultural centers. The data were collected by Mohammad Khani’s self-report questionnaire, Neff's self-compassion scale and coping strategies of Blings and Mous. The findings showed that emotional abuse with mean of 23.54 was the hisgest and physical abuse with mean of 7.87 was the lowest one. Results showed that there is negative relationship between the abuse’s total score and self-compassion’s total score. All physical abuse's subscales, emotional abuse and negligence can predict the self-compassion except sexual abuse. Also none of the abuse subscales can predict the stress-coping methods. The results have shown that the experience of abuse in childhood injury ,can be affected him in adulthood on self-concept and coping responces to stress and problems.

The Earth's magnetic field (EMF) is recorded in archeological baked materials carrying a stable remanent magnetization. This magnetic record can be used for indirectly date the archeological material by comparison with "reference curves" of the EMF. In this work we present magnetic inclination data from two different sites in southeastern Brazil, an ancient and a modern one: (a) a sampling at the ancient sugarcane mill Engenho Central de Piracicaba (ECP, 1881-1974 AD), and (b) a controlled survey at the modern brickyard Olaria Schiavolin (OS). Both of them are located in the city of Piracicaba, São Paulo State, Brazil. Magnetic measurements included stepwise thermal and alternating field demagnetization, anisotropy of magnetic susceptibility (AMS) and low-field magnetic susceptibility vs. temperature. In OS, we collected 40 oriented bricks from 5 sampling points inside the brickyard oven in order to test the stability and reliability of their remanent magnetizations by comparing them with the local field (measured directly with a fluxgate magnetometer). We observed differences of +/- 3° between the local field and the IGRF. When magnetic inclinations are reported relative to the flat planes of the brick (the situation we face for real ancient bricks), the differences due to inclination of the burning plane and magnetic anomalies inside the oven never exceed 6°. These differences are averaged out by using a minimum of 6 bricks (~24 specimens) per sampling point to compute the inclination. In the ancient site ECP we collected 140 non-oriented bricks from 14 different walls; three of them were previously dated using historical records. Inclinations were defined using at least 6 bricks per wall, showing consistent average values within the same walls. When compared to the IGRF and GUFM1 models, the inclinations obtained for the dated walls agreed within the experimental error. We have then applied the same procedure to estimate the age of the remaining walls. Using

The Clementine mission provided the first ever complete, systematic surface mapping of the moon from the ultra-violet to the near-infrared regions. More than 1.7 million images of the moon, earth and space were returned from this mission. Two star stracker stellar compasses (star tracker camera + stellar compass software) were included on the spacecraft, serving a primary function of providing angle updates to the guidance and navigation system. These cameras served a secondary function by providing a wide field of view imaging capability for lunar horizon glow and other dark-side imaging data. This 290 g camera using a 576 x 384 focal plane array and a 17 mm entrance pupil, detected and centroided stars as dim and dimmer than 4.5 m{sub v}, providing rms pointing accuracy of better than 100 {mu}rad pitch and yaw and 450 {mu}rad roll. A description of this light-weight, low power star tracker camera along with a summary of lessons learned is presented. Design goals and preliminary on-orbit performance estimates are addressed in terms of meeting the mission`s primary objective for flight qualifying the sensors for future Department of Defense flights. Documentation generated during the design, analysis, build, test and characterization of the star tracker cameras are presented. Collectively, this documentation represents a small library of information for this camera, and may be used as a framework for producing copy units by commercial enterprises, and therefore satisfies a Department of Defense and Department of Energy goal to transfer technology to industry. However, the considerable knowledge gained from the experience of the individuals involved in the system trades, design, analysis, production, testing and characterization of the star tracker stellar compass is not contained in this documentation.

2015-01-01

Altering speed and moving on a gradient can affect an animal’s posture and gait, which in turn can change the energetic requirements of terrestrial locomotion. Here, the energetic and kinematic effects of locomoting on an incline were investigated in the Indian peacock, Pavo cristatus. The mass-specific metabolic rate of the Indian peacock was elevated on an incline, but this change was not dependent on the angle ascended and the cost of lifting remained similar between the two inclines (+5 a...

This paper reports on probe measurements of the electron energy distribution function and plasma potential in the divertor region of the COMPASS tokamak during D-shaped plasmas. The probe data have been processed using the novel first-derivative technique. A comparison with the results obtained by processing the same data with the classical probe technique, which assumes Maxwellian electron energy distribution functions is presented and discussed. In the vicinity of the inner and outer strike points of the divertor the electron energy distribution function can be approximated by a bi-Maxwellian, with a dominating low-energy electron population (4-7 eV) and a minority of higher energy electrons (12-25 eV). In the private flux region between the two strike points the electron energy distribution function is found to be Maxwellian with temperatures in the range of 7-10 eV. The comparative analysis using both techniques has allowed a better insight into the underlying physical processes at the divertor region of the COMPASS tokamak.

Loading factor and inclination parameter of diagonal type MHD generators

International Nuclear Information System (INIS)

Ishikawa, Motoo

1979-01-01

Regarding diagonal type MHD generators is studied the relation between the loading factor and inclination parameter which is required for attaining the maximum power density with a given electrical efficiency on the assumption of infinitely segmented electrodes. The average current density on electrodes is calculated against the Hall parameter, loading factor, and inclination parameter. The diagonal type generator is compared with Faraday type generator regarding the average current density. Decreasing the loading factor from inlet to outlet is appropriate to small size generators but increasing to large size generators. The inclination parameter had better decrease in both generators, being smaller for small generators than for large ones. The average current density on electrodes of diagonal type generators varies less with the loading factor than the Faraday type. In large size generators its value can become smaller compared with that of the Faraday type. (author)

There are numerous multi-planet systems that have now been detected via a variety of techniques. These systems exhibit a range of both planetary properties and orbital configurations. For those systems without detected planetary transits, a significant unknown factor is the orbital inclination. This produces an uncertainty in the mass of the planets and their related properties, such as atmospheric scale height. Here we investigate the HD 10180 system, which was discovered using the radial velocity technique. We provide a new orbital solution for the system which allows for eccentric orbits for all planets. We show how the inclination of the system affects the mass/radius properties of the planets and how the detection of phase signatures may resolve the inclination ambiguity. We finally evaluate the Habitable Zone properties of the system and show that the g planet spends 100% of an eccentric orbit within the Habitable Zone.

Kim, Hyoung Tak; Bang, Kwang Hyun; Suh, Jung Soo

2013-01-01

In order to investigate boiling behavior on downward-facing inclined heated wall prior to the CHF condition, an experiment was carried out with 1.2 m long rectangular channel, inclined by 10 .deg. from the horizontal plane. High speed video images showed that the bubbles were sliding along the heated wall, continuing to grow and combining with the bubbles growing at their nucleation sites in the downstream. These large bubbles continued to slide along the heated wall and formed elongated slug bubbles. Under this slug bubble thin liquid film layer on the heated wall was observed and this liquid film prevents the wall from dryout. The length, velocity and frequency of slug bubbles sliding on the heated wall were measured as a function of wall heat flux and these parameters were used to develop wall boiling model for inclined, downward-facing heated wall. One approach to achieve coolable state of molten core in a PWR-like reactor cavity during a severe accident is to retain the core melt on a so-called core catcher residing on the reactor cavity floor after its relocation from the reactor pressure vessel. The core melt retained in the core catcher is cooled by water coolant flowing in an inclined cooling channel underneath as well as the water pool overlaid on the melt layer. Two-phase flow boiling with downward-facing heated wall such as this core catcher cooling channel has drawn a special attention because this orientation of heated wall may reach boiling crisis at lower heat flux than that of a vertical or upward-facing heated wall. Nishikawa and Fujita, Howard and Mudawar, Qiu and Dhir have conducted experiments to study the effect of heater orientation on boiling heat transfer and CHF. SULTAN experiment was conducted to study inclined large-scale structure coolability by water in boiling natural convection. In this paper, high-speed visualization of boiling behavior on downward-facing heated wall inclined by 10 .deg. is presented and wall boiling model for the

Computational stability appraisal of rectangular natural circulation loop: Effect of loop inclination

Highlights: • Computational model developed for single-phase rectangular natural circulation loop. • Role of loop inclination to vertical on thermalhydraulic stability is explored. • Inclination has strong stabilizing effect due to lower effective gravitation force. • Increase in tilt angle reduces settling time and highest amplitude of oscillation. • An angle of 15° is suggested for the selected loop geometry. - Abstract: Controlling stability behavior of single-phase natural circulation loops, without significantly affecting its steady-state characteristics, is a topic of wide research interest. Present study explores the role of loop inclination on a particular loop geometry. Accordingly a 3D computational model of a rectangular loop is developed and transient conservation equations are solved to obtain the temporal variation in flow parameters. Starting from the quiescent state, simulations are performed for selected sets of operating conditions and also with a few selected inclination angles. System experiences instability at higher heater powers and also with higher sink temperatures. Inclination is found to have a strong stabilizing influence owing to the reduction in the effective gravitational acceleration and subsequent decline in local buoyancy effects. The settling time and highest amplitude of oscillations substantially reduces for a stable system with a small inclination. Typically-unstable systems can also suppress the oscillations, when subjected to tilting, within a reasonable period of time. It is possible to stabilize the loop within shorter time span by increasing the tilt angle, but at the expense of reduction in steady-state flow rate. Overall a tilt angle of 15° is suggested for the selected geometry. Results from the 3D model is compared with the predictions from an indigenous 1D code. While similar qualitative influence of inclination is observed, the 1D model predicts early appearance of the stability threshold and hence hints

Characterization and improvement of highly inclined optical sheet microscopy

Highly Inclined and Laminated Optical sheet (HILO) microscopy is an optical technique that employs a highly inclined laser beam to illuminate the sample with a thin sheet of light that can be scanned through the sample volume1 . HILO is an efficient illumination technique when applied to fluorescence imaging of thick samples owing to the confined illumination volume that allows high contrast imaging while retaining deep scanning capability in a wide-field configuration. The restricted illumination volume is crucial to limit background fluorescence originating from portions of the sample far from the focal plane, especially in applications such as single molecule localization and super-resolution imaging2-4. Despite its widespread use, current literature lacks comprehensive reports of the actual advantages of HILO in these kinds of microscopies. Here, we thoroughly characterize the propagation of a highly inclined beam through fluorescently labeled samples and implement appropriate beam shaping for optimal application to single molecule and super-resolution imaging. We demonstrate that, by reducing the beam size along the refracted axis only, the excitation volume is consequently reduced while maintaining a field of view suitable for single cell imaging. We quantify the enhancement in signal-tobackground ratio with respect to the standard HILO technique and apply our illumination method to dSTORM superresolution imaging of the actin and vimentin cytoskeleton. We define the conditions to achieve localization precisions comparable to state-of-the-art reports, obtain a significant improvement in the image contrast, and enhanced plane selectivity within the sample volume due to the further confinement of the inclined beam.

Precise on-machine extraction of the surface normal vector using an eddy current sensor array

2016-01-01

To satisfy the requirements of on-machine measurement of the surface normal during complex surface manufacturing, a highly robust normal vector extraction method using an Eddy current (EC) displacement sensor array is developed, the output of which is almost unaffected by surface brightness, machining coolant and environmental noise. A precise normal vector extraction model based on a triangular-distributed EC sensor array is first established. Calibration of the effects of object surface inclination and coupling interference on measurement results, and the relative position of EC sensors, is involved. A novel apparatus employing three EC sensors and a force transducer was designed, which can be easily integrated into the computer numerical control (CNC) machine tool spindle and/or robot terminal execution. Finally, to test the validity and practicability of the proposed method, typical experiments were conducted with specified testing pieces using the developed approach and system, such as an inclined plane and cylindrical and spherical surfaces.

Passive Corium Cooling System (CCS) provides a function of ex-vessel debris cooling and molten core stabilization during a severe accident. CCS features inclined cooling channels arranged axi-symmetrically below the core-catcher basin. In order to estimate the coolability of the inclined cooling channel, it is indispensable to identify the flow pattern of the two-phase flow in the cooling channel. Several former studies for the two-phase flow pattern in the inclined channel are referred. Taitel and Dukler (1976) developed a prediction method of the flow pattern transition in horizontal and near horizontal tubes. Barnea et al. (1980) showed the flow pattern map of upward flow with 10 degrees inclination. Sakaguti et al. (1996) observed the two-phase flow patterns in the horizontal pipe connected with slightly upward pipe, in which the flow pattern in the pipe with a bending part was expressed by the combination of a basic flow pattern and some auxiliary flow patterns. Then we investigated these studies In order to identify the flow patterns observed in the inclined cooling channel of CCS. Furthermore we experimentally observed the flow patterns in the inclined cooling channel with various inlet conditions. As a result of the investigation and observation, typical flow patterns in the inclined cooling channel were identified. Two typical flow patterns were observed depending on the steam flow rate, one of which is 'elongated bubble 'flow, and the other is 'churn with collapsing backward and upward slug 'flow The flow and heat transfer in the inclined channel of CCS is analyzed by using a two-phase analysis code employing two-fluid model in which the constitutive equations for the two-phase flow in inclined channels are incorporated. That is, drift flux parameter for each of the elongated bubble flow, and the churn with collapsing backward and upward slug flow are incorporated to the two-phase analysis code, which are based on the rising velocity of the long bubble in

La Scaleia, Barbara; Lacquaniti, Francesco; Zago, Myrka

2014-01-01

It is known that humans tend to misjudge the kinematics of a target rolling down an inclined plane. Because visuomotor responses are often more accurate and less prone to perceptual illusions than cognitive judgments, we asked the question of how rolling motion is extrapolated for manual interception or drawing tasks. In three experiments a ball rolled down an incline with kinematics that differed as a function of the starting position (4 different positions) and slope (30°, 45° or 60°). In Experiment 1, participants had to punch the ball as it fell off the incline. In Experiment 2, the ball rolled down the incline but was stopped at the end; participants were asked to imagine that the ball kept moving and to punch it. In Experiment 3, the ball rolled down the incline and was stopped at the end; participants were asked to draw with the hand in air the trajectory that would be described by the ball if it kept moving. We found that performance was most accurate when motion of the ball was visible until interception and haptic feedback of hand-ball contact was available (Experiment 1). However, even when participants punched an imaginary moving ball (Experiment 2) or drew in air the imaginary trajectory (Experiment 3), they were able to extrapolate to some extent global aspects of the target motion, including its path, speed and arrival time. We argue that the path and kinematics of a ball rolling down an incline can be extrapolated surprisingly well by the brain using both visual information and internal models of target motion.
