    Full Text Available The process through which an observer allocates his/her attention based on the attention of another person is known as joint attention. To be able to do this, the observer effectively has to compute where the other person is looking. It has been shown that observers integrate information from the head and the eyes to determine the gaze of another person. Most studies have documented that observers show a bias called the overshoot effect when eyes and head are misaligned. The present study addresses whether body information is also used as a cue to compute perceived gaze direction. In Experiment 1, we observed a similar overshoot effect in both behavioral and saccadic responses when manipulating body orientation. In Experiment 2, we explored whether the overshoot effect was due to observers assuming that the eyes are oriented further than the head when head and body orientation are misaligned. We removed horizontal eye information by presenting the stimulus from a side view. Head orientation was now manipulated in a vertical direction and the overshoot effect was replicated. In summary, this study shows that body orientation is indeed used as a cue to determine where another person is looking.

    We evaluated personality change following head injury in 68 patients at 6 months postinjury using the NEO Five-Factor Inventory to assess the five personality dimensions of the Five-Factor Model of Personality. All items had to be rated twice, once for the preinjury and once for the current status. Twenty-eight trauma patients with injuries to other parts of the body than the head were used as controls. For the head-injured group, 63 relatives also completed the questionnaire. The results showed no differences between the ratings of head-injured patients and the ratings of trauma control patients. Both groups showed significant change in the personality dimensions Neuroticism, Extraversion, and Conscientiousness. Compared to their relatives, head-injured patients report a smaller change in Extraversion and Conscientiousness. Changes were not reported on the Openness and Agreeableness scales, by neither the head-injured or their relatives, nor by the trauma controls.

    Context: Very few women have leadership positions in athletic training (ie, head athletic training positions) in intercollegiate athletics. Research exists on the barriers to attaining the role; however, our understanding about the experiences of those currently engaged in the role is limited. Objective: To examine the experiences of female head athletic trainers as they worked toward and attained the position of head athletic trainer. Design: Qualitative study. Setting: National Collegiate Athletic Association Division I setting. Patients or Other Participants: Eight female athletic trainers serving in the role of head athletic trainer participated in our study. The mean age of the participants was 45 ± 12 years, with 5 ± 1.5 years of experience in the role of head athletic trainer and 21 ± 10 years of experience as athletic trainers. Data Collection and Analysis: We conducted phone interviews with the 8 participants following a semistructured format. Interviews were transcribed verbatim and analyzed following a general inductive approach as described by Thomas. To establish credibility, we used a peer reviewer, member checks, and multiple-analyst triangulation. Results: Six major themes emerged from our analysis regarding the experiences of female head athletic trainers. Opportunities to become a head athletic trainer, leadership qualities, and unique personal characteristics were discussed as factors leading to the assumption of the role of the head athletic trainer. Where women hold back, family challenges, and organizational barriers speak to the potential obstacles to assuming the role of head athletic trainer. Conclusions: Female head athletic trainers did not seek the role, but through persistence and encouragement, they find themselves assuming the role. Leadership skills were discussed as important for success in the role of head athletic trainer. Life balancing and parenting were identified as barriers to women seeking the role of head athletic

    Full Text Available Human head lice and body lice are morphologically and biologically similar but have distinct ecologies. They were shown to have almost the same basic genetic content (one gene is absent in head lice, but differentially express certain genes, presumably responsible for the vector competence. They are now believed to be ecotypes of the same species (Pediculus humanus and based on mitochondrial studies, body lice have been included with head lice in one of three clades of human head lice (Clade A. Here, we tested whether head and body lice collected from the same host belong to the same population by examining highly polymorphic intergenic spacers. This study was performed on lice collected from five homeless persons living in the same shelter in which Clade A lice are prevalent. Lice were individually genotyped at four spacer loci. The genetic identity and diversity of lice from head and body populations were compared for each homeless person. Population genetic structure was tested between lice from the two body regions and between the lice from different host individuals.We found two pairs of head and body lice on the same homeless person with identical multi locus genotypes. No difference in genetic diversity was found between head and body louse populations and no evidence of significant structure between the louse populations was found, even after controlling for a possible effect of the host individual. More surprisingly, no structure was obvious between lice of different homeless persons.We believe that the head and body lice collected from our five subjects belong to the same population and are shared between people living in the same shelter. These findings confirm that head and body lice are two ecotypes of the same species and show the importance of implementing measures to prevent lice transmission between homeless people in shelters.

    Full Text Available The article is devoted to methodological foundations of research of leader’s personal qualities. In difference from the previous work, which was devoted to a research of personal qualities of heads, including civil officers, at works of Plato, Aristotle and M. Weber, where were shown empirical models of structure of personal qualities of heads: instrumental-rational and value-rational social actions. This publication presents the empirical models of structure of personal qualities of heads of affective type of M. Weber’s social action. Thanks to it, M. Weber’s concept about social action receives one more approach to verification in practice. The following directions of social researches are allocated. The first direction. When in structure of personal qualities the emotional component is a dominant (“emotional unbalance”, in comparison with intellectual, moral, strong-willed and other personal qualities (diplomacy, social experience, and so forth. Those people, whose indicators of emotional unbalance are in extreme, in maximum borders - carry to psychopaths and they are an object of clinical psychology and medicine. The second direction. When in structure of personal qualities emotional unbalance competes on equal terms (equally has bright difference, a deviation from average values to intellectual, moral and strong-willed qualities. The third direction. When in structure of personal qualities intellectual, moral and strong-willed and others personal qualities dominate over affective lines.

    2007-01-01

    Despite an emerging literature characterizing the neuropsychological profiles of borderline, antisocial, and schizotypal personality disorders, relations between personality disorder traits and neurocognitive domains remain unknown. The authors examined associations among Millon Clinical Multiaxial Inventory-III personality disorder scales and eight neuropsychological domains in 161 patients referred for neuropsychological evaluation following closed head injury. Most personality disorder scales were associated with some decrement in cognitive function, particularly speeded processing, executive function, and language, while histrionic and narcissistic scales had positive relations with neuropsychological functioning. Results suggest that many personality disorder traits are related to neurocognitive function, particularly those functions subserved by frontal and temporal regions.

    Full Text Available BACKGROUND AND OBJECTIVE: Borderline personality disorder which constantly changes the mood, identity and interpersonal relationship is a mental disorder classified in category B. Besides, it leads to behaviors such as drug abuse, impulsive sex and suicide which make more difficult the treatment of these patients. The aim of this study was to report the recovery of a personality problem in a case with borderline personality disorder after the head trauma. CASE REPORT: The personality signs of a 28-year-old boy who had the full criteria of borderline personality disorder including drug abuse, impulsivity, mood instability, periods of anger and aggression were significantly decreased after hitting. Personality difference and improvement of patient were shown in MMPI test and MRI indicated the structural changes in his brain. He had no problem in 4-year-follow up. CONCLUSION: This report suggested the personality and behavioral changes after head trauma. MRI results indicated that the recovery is probably caused by the destruction area in the frontal lobe and the anterior temporal lobe (near the hippocampus. Thus the importance of neuropsychological factors should be considered in creating the diagnostic criteria.

  9. Head Transplants and Personal Identity: A Philosophical and Literary Survey.

    The criterion of personal identity is clearly called into question by the project to perform a human head transplant. Is identity provided by psychological continuity alone, or does it depend on bodily continuity as well? And how do these different perspectives interface with our notion of mind and mind-body relationship? The reader will be provided with a discussion concerning these problems, together with a philosophical and literary survey about the conception of body-mind relationship from the Greek thought to contemporary philosophy. The analysis will conclude with a discussion concerning the possibility to consider the issue of personal identity from a statistic point of view, which privileges the general perception of identity, so as it has been shaped by the cultural trends of the last four centuries. It could hence be argued that personal identity is not something which can be defined once and for all. On the contrary, the general perception of identity is subject to significant alterations resulting from one's cultural environment. However, the cultural environment itself can be changed by particularly notable events, such as, hypothetically, the successful outcome of a human head transplant. © 2016 John Wiley & Sons Ltd.

    Brood parasites face considerable cognitive challenges in locating and selecting host nests for their young. Here, we test whether female brown-headed cowbirds, Molothrus ater , could use information acquired from observing the nest prospecting patterns of conspecifics to influence their own patterns of nest selection. In laboratory-based experiments, we created a disparity in the amount of personal information females had about the quality of nests. Females with less personal information about the quality of two nests spent more time investigating the nest that more knowledgeable females investigated. Furthermore, there was a strong negative relationship between individual's ability to track nest quality using personal information and their tendency to copy others. These two contrasting strategies for selecting nests are equally effective, but lead to different patterns of parasitism. © 2017 The Author(s).

  11. Piezosurgery in head and neck oncological and reconstructive surgery: personal experience on 127 cases

    2009-01-01

    Summary Piezoelectric bone surgery, known simply as piezosurgery, is a new technique of osteotomy and osteoplasty, which requires the use of microvibrations of ultrasonic frequency scalpels. The principle of piezosurgery is ultrasonic transduction, obtained by piezoelectric ceramic contraction and expansion. The vibrations thus obtained are amplified and transferred onto the insert of a drill which, when rapidly applied, with slight pressure, upon the bony tissue, results, in the presence of irrigation with physiological solution, in the cavitation phenomenon, with a mechanical cutting effect, exclusively on mineralized tissues. Personal experience with the use of piezosurgery in head and neck oncological and reconstructive surgery is relatively recent, having been developed in 2002-2006, and, so far, involves 127 cases; preliminary results are interesting and improving in the, hopefully, developmental phases of inserts with specific geometrics on account of the characteristics of the various aspects of surgical ENT operations. Furthermore, with piezoelectric surgery it has been possible to perform precise osteotomy lines, micrometric and curvilinear with absolute confidence, particularly in close proximity to the vessels and nerves and other important facial structures (dura mater). There can be no doubt, since this is a new cutting method, that piezosurgery involves a different learning curve compared to other techniques, requiring obstacles of a psychological nature to be overcome as well as that concerning surgical expertise. Given the numbers of cases treated and the relative power of this instrument, analysis of complications, intra-operative time (which would appear, on average, to be 20% longer) and, therefore, morbility, shows interesting potentiality of the technique. This new ultrasound cutting method will, no doubt, in the future, be increasingly used in ENT surgery, particularly with improvements in power and geometry of the inserts, with possible

  12. Wheelchair control by head motion

    Full Text Available Electric wheelchairs are designed to aid paraplegics. Unfortunately, these can not be used by persons with higher degree of impairment, such as quadriplegics, i.e. persons that, due to age or illness, can not move any of the body parts, except of the head. Medical devices designed to help them are very complicated, rare and expensive. In this paper a microcontroller system that enables standard electric wheelchair control by head motion is presented. The system comprises electronic and mechanic components. A novel head motion recognition technique based on accelerometer data processing is designed. The wheelchair joystick is controlled by the system’s mechanical actuator. The system can be used with several different types of standard electric wheelchairs. It is tested and verified through an experiment performed within this paper.

    Introduction: In the face of growing demand in radiology, skill mix initiatives have sought to improve and expand service provision. Within the UK radiographer reporting is now widespread, although the growth in computerised tomography (CT) head reporting has not been as rapid as anticipated. The literature in this area is limited, but case studies have highlighted the successful implementation of this training through new radiographer roles in practice. Method: A cross-sectional survey was developed to elicit information from radiographers and managers on their experiences before, during and after post-graduate training in CT head reporting. Results: Seventy one responses were received comprising 48 past students (n = 48/111; 43.2%) and 23 service managers (n = 23/67; 34.3%). Key factors for the development were personal continual professional development for students and departmental need for managers. Challenges during training included a lack of study time due to staff shortages and access to radiologist mentors. Only 48.8% of students responding have gone on to use the new skills in practice cited reasons include staff shortages, resistance from radiologists and increase in radiological staffing. Conclusions: This qualitative study has demonstrated that those trusts who have implemented CT head reporting have evidenced perceptible benefits for both the department and individuals. Those radiographers who are successfully reporting have shown themselves to be highly motivated and persistent in their development

    In clinical settings, there is substantial evidence both clinically and empirically to suggest that approximately 50% of individuals with borderline personality disorder experience auditory verbal hallucinations. However, there is limited research investigating the phenomenology of these voices. The aim of this study was to review and compare our current understanding of auditory verbal hallucinations in borderline personality disorder with auditory verbal hallucinations in patients with a psychotic disorder, to critically analyse existing studies investigating auditory verbal hallucinations in borderline personality disorder and to identify gaps in current knowledge, which will help direct future research. The literature was searched using the electronic database Scopus, PubMed and MEDLINE. Relevant studies were included if they were written in English, were empirical studies specifically addressing auditory verbal hallucinations and borderline personality disorder, were peer reviewed, used only adult humans and sample comprising borderline personality disorder as the primary diagnosis, and included a comparison group with a primary psychotic disorder such as schizophrenia. Our search strategy revealed a total of 16 articles investigating the phenomenology of auditory verbal hallucinations in borderline personality disorder. Some studies provided evidence to suggest that the voice experiences in borderline personality disorder are similar to those experienced by people with schizophrenia, for example, occur inside the head, and often involved persecutory voices. Other studies revealed some differences between schizophrenia and borderline personality disorder voice experiences, with the borderline personality disorder voices sounding more derogatory and self-critical in nature and the voice-hearers' response to the voices were more emotionally resistive. Furthermore, in one study, the schizophrenia group's voices resulted in more disruption in daily functioning

  15. Person-Independent Head Pose Estimation Using Biased Manifold Embedding

    2008-02-01

    Full Text Available Head pose estimation has been an integral problem in the study of face recognition systems and human-computer interfaces, as part of biometric applications. A fine estimate of the head pose angle is necessary and useful for several face analysis applications. To determine the head pose, face images with varying pose angles can be considered to be lying on a smooth low-dimensional manifold in high-dimensional image feature space. However, when there are face images of multiple individuals with varying pose angles, manifold learning techniques often do not give accurate results. In this work, we propose a framework for a supervised form of manifold learning called Biased Manifold Embedding to obtain improved performance in head pose angle estimation. This framework goes beyond pose estimation, and can be applied to all regression applications. This framework, although formulated for a regression scenario, unifies other supervised approaches to manifold learning that have been proposed so far. Detailed studies of the proposed method are carried out on the FacePix database, which contains 181 face images each of 30 individuals with pose angle variations at a granularity of 1∘. Since biometric applications in the real world may not contain this level of granularity in training data, an analysis of the methodology is performed on sparsely sampled data to validate its effectiveness. We obtained up to 2∘ average pose angle estimation error in the results from our experiments, which matched the best results obtained for head pose estimation using related approaches.

    The prevalence and severity of dysphagia in people treated non-surgically for primary head and neck cancer (HNC) is well documented. However, few studies have looked beyond the physiological impairment to explore the lived experience of dysphagia in the post-treatment period of HNC. The current study adopted a person-centred, qualitative approach to describe the experiences of people living with dysphagia in the months and years following non-surgical treatment for HNC. Using maximum variation sampling, 24 participants who had undergone radiotherapy treatment for HNC were recruited. Individual interviews were conducted to explore the impact of dysphagia on participants' everyday lives. The themes identified included: (1) physical changes related to swallowing; (2) emotions evoked by living with dysphagia; (3) altered perceptions and changes in appreciation of food; and (4) personal and lifestyle impacts. The data revealed the breadth and significance of the impact of dysphagia on the lives of people treated curatively for HNC. Assessment and management in the post-treatment period must be sufficiently holistic to address both the changing physical states and the psychosocial needs of people with dysphagia following HNC. Rehabilitation services which focus only on impairment-based management will fail to fully meet the support needs of this clinical population.

    In this work, we present a method for estimating 3-D motion parameters; this method provides an alternative way for 3D head pose estimation from image sequence in the current computer vision literature. This method is robust over extended sequences and large head motions and accurately extracts the orientation angles of head from a single view. Experimental results show that this tracking system works well for development a human-computer interface for people that possess severe motor incapacity

    The results and analysis are described of a downcomer effective water head experiment. Downcomer effective water head is the driving force to feed an emergency coolant to the core during a reflood phase of PWR LOCA. The test rig has dimensions of the full-scale height and gap. Experimental conditions are: downcomer wall temperature = 250 0 -- 300 0 C, back pressure = 1 atm, coolant temperature = 98 0 -- 100 0 C, extraction water velocity = 0 -- 2 cm/s, and gap size = 200 mm. The effective water head histories obtained by experiment were compared with those predicted from the heat release from the downcomer walls. The heat release was calculated from the temperature histories indicated by thermocouples instrumented in and on the walls during experiment. The following were revealed: (1) The relation of heat flux and superheat (q vs ΔT sub(s)) obtained in the experiment is much different from that in pool boiling. (2) The predicted effective water head is in good agreement with the experimental one after 120 sec from the initiation of coolant injection. (3) The effect of extraction water velocity is negligible. (4) The effect of initial wall temperatures is evident. (author)

    Ultra poor women in Bangladesh are especially vulnerable to poverty and food insecurity, and they have generally been excluded from recent improvements in hunger and poverty rates in the country. An examination of the food provisioning narratives of 43 ultra poor female heads of household in Bangladesh was conducted in order to deepen understanding of this obstacle to the country's achievement of the First Millennium Development Goal. All participants were the household's sole income provider, had dependent children, and earned less than $1 USD per day. Women were purposively selected based on occupational group, context, and personal characteristics. Ethnographic interviews were conducted in January and February, 2008. Analysis of women's accounts of their daily food routine revealed chronic and pervasive food insecurity punctuated by acute episodes of absolute food deprivation that resulted from seasonal fluctuations in earnings, rising food prices, illness disrupting work, and healthcare costs. Women's accounts of their daily food provisioning experiences suggested compromises in, and trade-offs between, multiple basic needs as a result of inadequate income. Women were further constrained by social norms and gender roles that influenced their ability to work outside the home. Our method of inquiry led us to construct an organizing framework that extends knowledge of ultra poor women in Bangladesh's complex and multi-sphered experience of poverty and food insecurity. Based on these findings, we propose a strategy called whole person development (WPD), which seeks small adjustments to services, programs, and policies based on leverage points identified through in-depth narratives.

    This study investigated the gender dynamics of living in child-headed households (CHHs) in a rural area in Swaziland that experiences high levels of drought, poverty and HIV and AIDS. Using a qualitative research methodology, the study examined ways in which children in CHHs meet their daily family needs and address their vulnerabilities according to their gender, focusing on the experiences of the children. The study sample consisted of 10 households, with 5 boy and 5 girl-headed households from the chiefdoms within the area. A semi-structured interview guide was used to conduct interviews in the respondents' own homes. The study focused on the gendered coping strategies used by the children to sustain their household welfare. Three factors were examined: leadership, food provision and education. The findings show that birth order conferred headship or leadership to the eldest sibling irrespective of their gender. Variations in the performance of the three factors, which were influenced by the gender of the household head, were observed. Generally, the children acted in accordance with their socio-cultural norms demanded in fulfilling the role of leadership and food provision. Boy-headed households become disadvantaged because of the boys' reluctance to take tasks which would contravene traditional Swazi notions of masculinity. This was exacerbated by societal expectations of the independence of boys. Hegemonic masculinity puts boys at a disadvantage when societal expectations require them to enact their masculinity through independence, rather than by drawing on the support of their neighbours/family/social networks. However, girls conformed to traditional Swazi norms. Societal compassion with the vulnerability of girls produced sustainable social arrangements and fostered resilience in girl-headed households.

    2014-10-01

    Patients with head and neck neoplasms often experience a number of persistent treatment related symptoms including xerostomia. The impact of xerostomia can be profound and wearing on the patients, hence negatively influencing their quality of life. The purpose of this study was to explore the in-depth experiences of the patients living with radiation-induced xerostomia. This was a hermeneutic phenomenological study inspired by the Philosophy of Paul Ricoeur. Research data were retrieved with individual narratives from 15 patients diagnosed with head and neck neoplasm that underwent radiotherapy. Interpretation proceeded through three phases: naïve reading, structural analysis and comprehensive understanding. Five themes consisting of ten sub-themes emerged from the narratives reflecting on the patients' lived experiences. The themes were "suffering of the body", "suffering of the person's world", "being helpless against xerostomia", "suffering of the mind" and "being alone". The comprehensive understanding disclosed new possibilities for being-in-the world in relation to living with xerostomia. The precedent consideration of xerostomia mainly as a physical side-effect of radiotherapy was outweighed by the social and psychological effects revealed by this study. These xerostomia's effects are inflicted on the patients with an obvious reflection on their perceived quality of life. The findings call upon a shift towards acknowledging the severity of xerostomia and the need to care for these patients holistically. Copyright © 2014 Elsevier Ltd. All rights reserved.

Experiment of two-phase pump performance was conducted as a joint study of Japanese BWR user utilities and makers. Two-phase head and torque of three centrifugal pumps in high temperature and high pressure (around 6 MPa) steam/water were measured. Head was decreased from single-phase characteristics when gas was mixed in liquid flow in condition with normal flow and normal rotation directions. When flow rate was large enough, two-phase head was about the same as single-phase one in reversal flow conditions. Two-phase head was smoothly increased as flowing steam volumetic concentration increased when flow rate was small and flow direction was reversal. Changes of torque with gas concentration were correspondent to those of head. This suggested that changes of interaction between flow and impellers due to phase slip effected on torque which caused head differences between single- and two-phase flows. Dependence of dimensionless head and torque of three test pumps on steam concentration were almost the same as each other. (author)

    Sharing one's own immersive experience over the Internet is one of the ultimate goals of telepresence technology. In this paper, we present JackIn Head, a visual telepresence system featuring an omnidirectional wearable camera with image motion stabilization. Spherical omnidirectional video footage taken around the head of a local user is stabilized and then broadcast to others, allowing remote users to explore the immersive visual environment independently of the local user's head direction. We describe the system design of JackIn Head and report the evaluation results of real-time image stabilization and alleviation of cybersickness. Then, through an exploratory observation study, we investigate how individuals can remotely interact, communicate with, and assist each other with our system. We report our observation and analysis of inter-personal communication, demonstrating the effectiveness of our system in augmenting remote collaboration.

  11. Experiment on performance of upper head injection system with ROSA-II

    International Nuclear Information System (INIS)

    1976-09-01

    Thermo-hydraulic behavior in the primary cooling system of a pressurized water reactor with an upper head injection system (UHI) in a postulated loss-of-coolant accident (LOCA) has been studied with ROSA-II test facility. Simulated UHI and internal structures of the pressure vessel were installed to the facility for the experiment. Nine maximum-sized double-ended break tests and one medium-sized split break test were performed for the cold-leg break condition. The results are as follows: (1) Fluid mixing in the upper head is not perfect. (2) Cold water injection into the steam or two-phase fluid causes violent depressurization due to the condensation. Flow pattern in the primary cooling system is largely influenced by the above two. (auth.)

It is found that the outcome of consumers' choice between organic and non-organic wine depends on their personal (moral) norms......This study investigates whether the behavioral influence of personal norms with regard to repeated pro-social behavior depends on direct experience of this behavior. Based on previous norm and attitude research, it is hypothesized that (i) direct experience strengthens the influence of personal......, after controlling for attitudes and subjective social norms.

    Full Text Available There is limited understanding of the experiences of women living with borderline personality disorder. It was therefore decided to discover how women living with this disorder would tell their life story. For the researcher, who worked in a psychotherapy ward where most women were living with borderline personality disorder, the care of these women was of vital importance, as they were less understood by mental health care providers.The research aimed to explore and describe the experiences of women living with borderline personality disorder. A qualitative, explorative, descriptive and contextual study design was used. Data was collected through in-depth phenomenological interviews that focused on the central question, “Tell me your life story”. Eight participants living with borderline personality disorder were interviewed. Tesch's method for data analysis was used (Creswell, 2009:186, along with an independent coder. Measures to ensure trustworthiness and ethical principles were applied throughout the research. From the findings obtained by means of the interviews of women living with borderline personality disorder, it was evident that there were childhood experiences of living in an unsafe space, related to unhealthy family dynamics, boundary violations and educational challenges. They experienced chronic feelings of emptiness in their relationships with theself. They also presented with a pattern of unstable interpersonal relationships and compromised mental health, which was apparent through the early on set of mental problems, emotional upheaval, looking for emotional escape and having different triggerfactors. Lastly, all these women yearned for facilitated mental health.

    2013-01-01

    Purpose: The aim was to explore the lived experience of physical therapy of persons with migraine. Method: Data were collected by conducting narrative interviews with 11 persons with migraine. Inspired by van Manen, a hermeneutic phenomenological method was used to analyse the experiences of physical therapy which these persons had. Results: Physical therapy for persons with migraine meant making an effort in terms of time and energy to improve their health by meeting a person who was utilising his or her knowledge and skill to help. Being respected and treated as an individual and having confidence in the physical therapist were highlighted aspects. The analysis revealed a main theme, “meeting a physical therapist with professional tools and a personal touch”. The main theme included four sub-themes, “investing time and energy to feel better”, “relying on the competence of the physical therapist”, “wanting to be treated and to become involved as an individual” and “being respected in a trustful relationship”. Conclusions: The therapeutic relationship with the physical therapist is important and the findings of this study can increase awareness about relational aspects of physical therapy and encourage thoughtfulness among physical therapists and other healthcare professionals interacting with persons with migraine.

  15. Surgeon-Manipulated Live Surgery Video Recording Apparatuses: Personal Experience and Review of Literature.

    Science.gov (United States)

    Kapi, Emin

    2017-06-01

    Visual recording of surgical procedures is a method that is used quite frequently in practices of plastic surgery. While presentations containing photographs are quite common in education seminars and congresses, video-containing presentations find more favour. For this reason, the presentation of surgical procedures in the form of real-time video display has increased especially recently. Appropriate technical equipment for video recording is not available in most hospitals, so there is a need to set up external apparatus in the operating room. Among these apparatuses can be listed such options as head-mounted video cameras, chest-mounted cameras, and tripod-mountable cameras. The head-mounted video camera is an apparatus that is capable of capturing high-resolution and detailed close-up footage. The tripod-mountable camera enables video capturing from a fixed point. Certain user-specific modifications can be made to overcome some of these restrictions. Among these modifications, custom-made applications are one of the most effective solutions. The article makes an attempt to present the features and experiences concerning the use of a combination of a head- or chest-mounted action camera, a custom-made portable tripod apparatus of versatile features, and an underwater camera. The descriptions we used are quite easy-to-assembly, quickly installed, and inexpensive apparatuses that do not require specific technical knowledge and can be manipulated by the surgeon personally in all procedures. The author believes that video recording apparatuses will be integrated more to the operating room, become a standard practice, and become more enabling for self-manipulation by the surgeon in the near future. This journal requires that authors assign a level of evidence to each article.

    Melt dispersion experiments with lateral failure in the bottom head were carried out in a 1:18 scaled annular cavity design under low pressure conditions. Water and a bismuth alloy were used as melt simulant material and nitrogen as driving gas. With lateral breaches the liquid height in the lower head relative to the upper and lower edge of the breach is an additional parameter for the dispersion process. Shifting the break from the central position towards the side of the lower head leads to smaller melt dispersion, and a larger breach size does not necessarily lead to a larger dispersed melt fraction.

Being respected and treated as an individual and having confidence in the physical therapist are important aspects of the therapeutic relationship and indicate a need for patient-centred care. By making the effort of spending the time and energy required, physical therapy could be a complement or an alternative to medication to ease the consequences of migraine.

    Mental ill-health, such as depression in the elderly, is a complex issue that is influenced by the life-world perspective of older persons. Their self-management ability should be strengthened based on an understanding of their situation, perspectives, and vulnerability. The aim of this study was to explore and increase understanding of old persons' lived experiences of depression and self-management using an interpretative explorative design. Understanding was developed by means of hermeneutic interpretation. One theme, Relationships and Togetherness, and four subthemes, A Sense of Carrying a Shoulder Bag, Walking on Eggshells, Holding the Reins, and Estrangement--a Loss of Togetherness, emerged. A collaborative approach can be important for empowering older persons through self-development and management. Although the findings of the present study cannot be considered conclusive or definitive, they nevertheless contribute new knowledge of older persons' lived experiences of depression in everyday life.

    Motherhood has been identified as a barrier to the head athletic trainer (AT) position. Role models have been cited as a possible facilitator for increasing the number of women who pursue and maintain this role in the collegiate setting. To examine the experiences of female ATs balancing motherhood and head AT positions in the National Collegiate Athletic Association Division II and III and National Association of Intercollegiate Athletics settings. Qualitative study. National Collegiate Athletic Association Divisions II and III and National Association of Intercollegiate Athletics. A total of 22 female head ATs (average age = 40 ± 8 years) who were married with children completed our study. Our participants had been certified for 15.5 ± 7.5 years and in their current positions as head ATs for 9 ± 8 years. We conducted online interviews with all participants. Participants journaled their reflections on a series of open-ended questions pertaining to their experiences as head ATs. Data were analyzed following a general inductive approach. Credibility was confirmed through peer review and researcher triangulation. We identified 3 major contributors to work-life conflict. Two speak to organizational influences on conflict: work demands and time of year. The role of motherhood, which was more of a personal contributor, also precipitated conflict for our ATs. Four themes emerged as work-life balance facilitators: planning, attitude and perspective, support networks, and workplace integration. Support was defined at both the personal and professional levels. In terms of the organization, our participants juggled long work hours, travel, and administrative tasks. Individually and socioculturally, they overcame their guilt and their need to be present and an active part of the parenting process. These mothers demonstrated the ability to cope with their demanding roles as both moms and head ATs.

  5. Compensating Victims of Personal Injury in Tort: The Nigerian Experience So Far

    Directory of Open Access Journals (Sweden)

    Oluwakemi ADEKILE

    2013-08-01

    Full Text Available This paper is a critical evaluation of the compensation system for personal injury tort in Nigeria. The present compensation system under the law of tort leaves many victims of personal injury uncompensated in Nigeria. This stems from many factors, including the fact that traditional tort theory of no liability without fault has continued to be the principal basis for liability. This is in spite of the heavy criticisms of the tort regime as an ineffective mode of compensation. Through an analytical assessment of selected core heads of claims in tort, the paper reveals the inadequacy in the foundations of tort law and its regulation of claims for personal injury in Nigeria. Implications: It finds that fault as the primary foundation of tort law in Nigeria creates a large volume of uncompensated plaintiffs, who, without an efficient alternative social security to fall upon, have to personally bear their losses. In the light of this, the paper uses examples from other jurisdictions to recommend that tort law in Nigeria is in need of more legislative intervention. Value: The paper recommends that the provision of a sustainable compensation system for personal injury is imperative for social justice in Nigeria.

  6. Head-mounted LED for optogenetic experiments of freely-behaving animal

    Recent developments in optogenetics have demonstrated the ability to target specific types of neurons with sub-millisecond temporal precision via direct optical stimulation of genetically modified neurons in the brain. In most applications, the beam of a laser is coupled to an optical fiber, which guides and delivers the optical power to the region of interest. Light emitting diodes (LEDs) are an alternative light source for optogenetics and they provide many advantages over a laser based system including cost, size, illumination stability, and fast modulation. Their compact size and low power consumption make LEDs suitable light sources for a wireless optogenetic stimulation system. However, the coupling efficiency of an LED's output light into an optical fiber is lower than a laser due to its noncollimated output light. In typical chronic optogenetic experiment, the output of the light source is transmitted to the brain through a patch cable and a fiber stub implant, and this configuration requires two fiber-to-fiber couplings. Attenuation within the patch cable is potential source of optical power loss. In this study, we report and characterize a recently developed light delivery method for freely-behaving animal experiments. We have developed a head-mounted light source that maximizes the coupling efficiency of an LED light source by eliminating the need for a fiber optic cable. This miniaturized LED is designed to couple directly to the fiber stub implant. Depending on the desired optical power output, the head-mounted LED can be controlled by either a tethered (high power) or battery-powered wireless (moderate power) controller. In the tethered system, the LED is controlled through 40 gauge micro coaxial cable which is thinner, more flexible, and more durable than a fiber optic cable. The battery-powered wireless system uses either infrared or radio frequency transmission to achieve real-time control. Optical, electrical, mechanical, and thermal

  7. Simplified realistic human head model for simulating Tumor Treating Fields (TTFields).

    Tumor Treating Fields (TTFields) are alternating electric fields in the intermediate frequency range (100-300 kHz) of low-intensity (1-3 V/cm). TTFields are an anti-mitotic treatment against solid tumors, which are approved for Glioblastoma Multiforme (GBM) patients. These electric fields are induced non-invasively by transducer arrays placed directly on the patient's scalp. Cell culture experiments showed that treatment efficacy is dependent on the induced field intensity. In clinical practice, a software called NovoTalTM uses head measurements to estimate the optimal array placement to maximize the electric field delivery to the tumor. Computational studies predict an increase in the tumor's electric field strength when adapting transducer arrays to its location. Ideally, a personalized head model could be created for each patient, to calculate the electric field distribution for the specific situation. Thus, the optimal transducer layout could be inferred from field calculation rather than distance measurements. Nonetheless, creating realistic head models of patients is time-consuming and often needs user interaction, because automated image segmentation is prone to failure. This study presents a first approach to creating simplified head models consisting of convex hulls of the tissue layers. The model is able to account for anisotropic conductivity in the cortical tissues by using a tensor representation estimated from Diffusion Tensor Imaging. The induced electric field distribution is compared in the simplified and realistic head models. The average field intensities in the brain and tumor are generally slightly higher in the realistic head model, with a maximal ratio of 114% for a simplified model with reasonable layer thicknesses. Thus, the present pipeline is a fast and efficient means towards personalized head models with less complexity involved in characterizing tissue interfaces, while enabling accurate predictions of electric field distribution.

    Identifying how persons with dementia experience lived space is important for enabling supportive living environments and creating communities that compensate for the fading capabilities of these persons. Several single studies have explored this topic; however, few studies have attempted to explicitly review and synthesize this research literature. The aim of this systematic meta-synthesis was therefore to interpret and synthesize knowledge regarding persons with dementia's experience of space. A systematic, computerized search of AgeLine, CINAHL Complete, Embase, Medline and PsycINFO was conducted using a search strategy that combined MeSH terms and text words for different types of dementia with different descriptions of experience. Studies with 1) a sample of persons with dementia, 2) qualitative interviews as a research method and 3) a description of experiences of lived space were included. The search resulted in 1386 articles, of which 136 were identified as eligible and were read and assessed using the CASP criteria. The analysis was inspired by qualitative content analyses. This interpretative qualitative meta-synthesis included 45 articles encompassing interviews with 672 persons with dementia. The analysis showed that living in one's own home and living in long-term care established different settings and posed diverse challenges for the experience of lived space in persons with dementia. The material revealed four main categories that described the experience of lived space: (1) belonging; (2) meaningfulness; (3) safety and security; and (4) autonomy. It showed how persons with dementia experienced a reduction in their lived space due to the progression of dementia. A comprehensive understanding of the categories led to the latent theme: "Living with dementia is like living in a space where the walls keep closing in". This meta-synthesis reveals a process whereby lived space gradually becomes smaller for persons with dementia. This underscores the

  10. The personal experience of time

    CERN Document Server

    Wessman, Alden

    1977-01-01

    The fundamental nature of human time experience has concerned artists, poets, philosophers, and scientists throughout the ages. Any consideration of human action requires awareness of its temporal aspects. However, simply to view time in the same units and dimensions as the physicist employs in describing events robs personal time of its "lived" quality. The use of physical time concepts in the description of human events is often artificial and misleading. It fails to account for the facts that human time estimates rarely match clock and calendar time; that societies and individuals demonstrate vast differences in their constructions and uses of time; and that temporal perceptions and attitudes change within an individual both during a single day and throughout his life span. The present volume does not view time as something that is sensed in the same way that one would sense or perceive spatial or sensory stimuli. Rather, it views time as a complex set of personally experienced cognitive constructs used by...

    2013-01-01

    This paper explores the intimate relationship experiences of the cisgender (i.e., not transgender) female partners of masculine-identifying transgender persons, with a particular focus on these partners' self-understanding of their sexual orientation. Limited research about this topic has been conducted to date. Semi-structured interviews were conducted with eight South African women who are or have been cisgender female partners of masculine-identifying trans persons. Although the interviews showed that the relationship experiences of female partners of masculine-identifying trans persons are diverse, several common themes emerged in the narratives. The way that participants labelled their sexual orientation did not change from before to after their relationship with a transgender partner. The participants reported varied family and community responses to their relationships. Specific emotional and informational support needs for women with transgender partners were identified.

  12. Remembering and knowing personality traits: figure/ground asymmetries in person-related retrieval experience.

    Science.gov (United States)

    Wehr, Thomas

    2008-01-01

    In two experiments, the effect of category salience on retrieval experience was investigated. In Experiment 1, participants rated typicality or concreteness of personality traits that differed in stereotype reference (i.e., consistent, inconsistent, and neutral in relation to the age stereotype). More remember judgments were given for consistent and inconsistent traits in contrast to neutral traits, thereby indicating a figure/ground asymmetry. In Experiment 2, neutral traits were excluded and a classical figure/ground phenomenon was demonstrated for the retrieval experience of traits (i.e., reversibility of an ambiguous figure after typicality and untypicality ratings). Altogether, the results suggest that metacognitive trait representations depend on principles of figure/ground asymmetries rather than on functional principles of social information processing.

    2011-01-01

    This paper introduces a method for the substantial reduction of heading errors in inertial navigation systems used under GPS-denied conditions. Presumably, the method is applicable for both vehicle-based and personal navigation systems, but experiments were performed only with a personal navigation system called 'personal dead reckoning' (PDR). In order to work under GPS-denied conditions, the PDR system uses a foot-mounted inertial measurement unit (IMU). However, gyro drift in this IMU can cause large heading errors after just a few minutes of walking. To reduce these errors, the map-matched heuristic drift elimination (MAPHDE) method was developed, which estimates gyro drift errors by comparing IMU-derived heading to the direction of the nearest street segment in a database of street maps. A heuristic component in this method provides tolerance to short deviations from walking along the street, such as when crossing streets or intersections. MAPHDE keeps heading errors almost at zero, and, as a result, position errors are dramatically reduced. In this paper, MAPHDE was used in a variety of outdoor walks, without any use of GPS. This paper explains the MAPHDE method in detail and presents experimental results

    We have determined absolute dimensions of the head and the relationship between the dimensions of its selected parts. The study enrolled adult subjects (mostly of Russian ethnicity) at the age from 17 to 22 years (1108 men and 1153 women). We calculated the normal values for the estimation of real dimensional characteristics and the frequency of their occurrence in the population. The proposed approach makes it possible to reliably identify the dimensional features of human appearance in terms of the quantitative verbal description (categories 1-5) and to reveal its most characteristic features. The results of this biometric study of the heads of unrecognized corpses obtained by the specially developed technology may be used in operational and search investigations, in the procedure of corpse identification, and forensic medical personality identification of a missing subject.

    We explored the impact of professional experience and personality on police officers' shooting performance under pressure. We recruited: (1) regular officers, (2) officers wanting to join a specialised arrest unit (AU) (expected to possess more stress-resistant traits; pre-AU) and (3) officers from this unit (expected to also possess more professional experience; AU) (all male). In Phase 1, we determined personality traits and experience. In Phase 2, state anxiety, shot accuracy, decision-making (shoot/don't shoot), movement speed and gaze behaviour were measured while officers performed a shooting test under low and high pressure. Results indicate minimal differences in personality among groups and superior performance of AU officers. Regression analyses showed that state anxiety and shooting performance under high pressure were first predicted by AU experience and second by certain personality traits. Results suggest that although personality traits attenuate the impact of high pressure, it is relevant experience that secures effective performance under pressure. Practitioner Summary: To obtain information for police selection and training purposes, we let officers who differed in personality and experience execute a shooting test under low and high pressure. Outcomes indicate that experience affected anxiety and performance most strongly, while personality traits of thrill- and adventure-seeking and self-control also had an effect.

    Elevated risk judgments for negative life events have been linked to personal experience with events. We tested the hypothesis that cognitive heuristics are the underlying cognitive mechanism for this relation. The availability (i.e., memory for incidents) and simulation (i.e., imagery) heuristics were evaluated as possible mediators for the relation between personal experience and risk estimates for fatal weather events. Adolescents who had experienced weather disasters estimated their personal risk for weather events. Support was obtained for the simulation heuristic (imagery) as a mediator for the relation. Availability for lightning disaster experience was also found to be a mediator for the relation between personal lightning disaster experience and risk estimate for future events. The implications for risk perception research are discussed.

    Full Text Available Context-aware e-learning is an educational model that foresees the selection of learning resources to make the e-learning content more relevant and suitable for the learner in his/her situation. The purpose of this paper is to demonstrate that an ontological approach can be used to define leaning contexts and to allow contextualizing learning experiences finding out relevant topics for each context. To do that, we defined a context model able to formally describe a learning context, an ontology-based model enabling the representation of a teaching domain (including context information and a methodology to generate personalized and context-aware learning experiences starting from them. Based on these theoretical components we improved an existing system for personalized e-learning with contextualisation features and experimented it with real users in two University courses. The results obtained from this experimentation have been compared with those achieved by similar systems.

  4. Imagining other people’s experiences in a person with impaired episodic memory: the role of personal familiarity

    Full Text Available Difficulties remembering one’s own experiences via episodic memory may affect the ability to imagine other people’s experiences during theory of mind (ToM. Previous work shows that the same set of brain regions recruited during tests of episodic memory and future imagining are also engaged during standard laboratory tests of ToM. However, hippocampal amnesic patients who show deficits in past and future thinking, show intact performance on ToM tests, which involve unknown people or fictional characters. Here we present data from a developmental amnesic person (H.C. and a group of demographically matched controls, who were tested on a naturalistic test of ToM that involved imagining other people’s experiences in response to photos of personally familiar others (‘pToM’ condition and unfamiliar others (‘ToM’ condition. We also included a condition that involved recollecting past experiences in response to personal photos (‘EM’ condition. Narratives were scored using an adapted autobiographical interview scoring procedure. Due to the visually rich stimuli, internal details were further classified as either descriptive (i.e., details that describe the visual content depicted in the photo or elaborative (i.e., details that go beyond what is visually depicted in the photo. Relative to controls, H.C. generated significantly fewer elaborative details in response to the pToM and EM photos and an equivalent number of elaborative details in response to the ToM photos. These data converge with previous neuroimaging results showing that the brain regions underlying pToM and episodic memory overlap to a greater extent than those supporting ToM. Taken together, these results suggest that detailed episodic representations supported by the hippocampus may be pivotal for imagining the experiences of personally familiar, but not unfamiliar, others.

    Health providers such as physicians, nurses and pharmacists should be knowledgeable about the biology of head lice and the ways to control them effectively, in order to reduce the proportion of children infested with head lice. To evaluate the knowledge of physicians in Israel on the biology and epidemiology of lice, as well as their experience with infested individuals and their preferences for diagnosis, prophylaxis and control. An anonymous questionnaire with 37 questions was used. The first 20 questions addressed the general knowledge of physicians on lice biology and control, while the remaining 17 questions were related to their personal experience with lice and louse treatment. Out of 273 physicians interviewed 66.8% had good knowledge of lice, while the remaining 33.2% had some knowledge on lice. The difference between the groups of physicians with medium and good knowledge on lice was borderline significant (P=0.0722), with the dermatologists borderline significantly less knowledgeable than the rest (P=0.0765). Significant differences were found between those physicians with 4-6 or 11-20 years of professional experience and the remaining groups (twice Pbiology and control was higher than male physicians (39.4% and 29.4%, respectively), the differences were borderline significant (P=0.09).

    Full Text Available Personality plays a role in human behavior, and thus can influence consumer decisions on environmental goods and services. This paper analyses the influence of the big five personality dimensions (extraversion, agreeableness, conscientiousness, neuroticism and openness in a discrete choice experiment dealing with preferences for the development of an environmental program for forest management in Spain. For this purpose, a reduced version of the Big Five Inventory survey (the BFI-10 is implemented. Results show a positive effect of openness and extraversion and a negative effect of agreeableness and neuroticism in consumers' preferences for this environmental program. Moreover, results from a latent class model show that personal traits help to explain preference heterogeneity.

  12. Seeking to understand lived experiences of personal recovery in personality disorder in community and forensic settings - a qualitative methods investigation.

    Shepherd, Andrew; Sanders, Caroline; Shaw, Jenny

    2017-08-01

    Understandings of personal recovery have emerged as an alternative framework to traditional ideas of clinical progression, or symptom remission, in clinical practice. Most research in this field has focussed on the experience of individuals suffering with psychotic disorders and little research has been conducted to explore the experience of individuals with a personality disorder diagnosis, despite the high prevalence of such difficulties. The nature of the personality disorder diagnosis, together with high prevalence rates in forensic settings, renders the understanding of recovery in these contexts particularly problematic. The current study seeks to map out pertinent themes relating to the recovery process in personality disorder as described by individuals accessing care in either community or forensic settings. Individual qualitative interviews were utilised to explore the lived experience of those receiving a personality disorder diagnosis and accessing mental health care in either community or forensic settings. A thematic analysis was conducted to identify shared concepts and understanding between participants. Fourty-one individual participant interviews were conducted across forensic and community settings. Recovery was presented by participants as a developing negotiated understanding of the self, together with looked for change and hope in the future. Four specific themes emerged in relation to this process: 1. Understanding early lived experience as informing sense of self 2. Developing emotional control 3. Diagnosis as linking understanding and hope for change 4. The role of mental health services. Through considering personal recovery in personality disorder as a negotiated understanding between the individual, their social networks and professionals this study illustrates the complexity of working through such a process. Clarity of understanding in this area is essential to avoid developing resistance in the recovery process. Understanding of

    An often-suggested factor in the aetiology of craniomandibular disorders (CMD) is an anteroposition of the head. However, the results of clinical studies to the relationship between CMD and head posture are contradictory. Therefore, the first aim of this study was to determine differences in head posture between well-defined CMD pain patients with or without a painful cervical spine disorder and healthy controls. The second aim was to determine differences in head posture between myogenous and arthrogenous CMD pain patients and controls. Two hundred and fifty persons entered the study. From each person, a standardized oral history was taken and blind physical examinations of the masticatory system and of the neck were performed. The participants were only included into one of the subgroups when the presence or absence of their symptoms was confirmed by the results of the physical examination. Head posture was quantified using lateral photographs and a lateral radiograph of the head and the cervical spine. After correction for age and gender effects, no difference in head posture was found between any of the patient and non-patient groups (P > 0.27). Therefore, this study does not support the suggestion that painful craniomandibular disorders, with or without a painful cervical spine disorder, are related to head posture.

    Numerical simulations offer a viable alternative to measurements for generating personalized head-related transfer functions (HRTFs). The fast multipole boundary element method (FM-BEM) is a popular method for simulating the HRTFs since it requires a surface mesh of the head (and torso) only....... The FM-BEM simulation of the HRTF at a single frequency can be computed in a few minutes. Utilizing cloud computing, the entire audible frequency range can be simulated in less than an hour. A bottleneck in the fast acquisition of the personalized HRTFs has been the complexity of generating good quality...... head models for the simulation. We compare three photography based geometry acquisition methods, ranging from a system of 52 cameras to a method using a single mobile phone camera only....

  15. Experiences With Insurance Plans and Providers Among Persons With Mental Illness.

    2016-03-01

    This study used nationally representative household survey data to examine the association between mental illness and experiences with usual care providers and health plans among persons with public or private insurance (N=25,176). Data were from the 2004-2012 Medical Expenditure Panel Surveys. Mental illness was assessed with symptom scales of serious psychological distress and depression at two time points, and persons were categorized by whether mental illness was episodic or persistent over time. Questions about experiences with providers (four questions) and plans (five questions) were based on the Consumer Assessment of Healthcare Providers and Systems survey. Rates of problems with plans and providers were reported for each category of mental illness, and multivariate regression was used to examine the association of problems with mental illness. Rates of problems with health plans were high, specifically for treatment approvals, finding information, and customer service, and were higher among persons with mental illness. Rates of problems with providers were lower than problems with plans, but persons with mental illness were more likely to report problems, specifically that doctors do not explain treatment options, respect treatment choices, or seek participation in decisions. Persons with mental illness reported experiencing more clinical and administrative problems at their usual source of care, although the reasons were not clear. Efforts by plans to improve health care before and after the clinical encounter and by providers to design treatments in line with patient preferences may improve experiences for all patients and particularly for those with mental illness.

    The associations of personality with activity participation and well-being have been well studied. However, less is known concerning the relationship between personality and specific aspects of activity engagement in older adults. We conducted a fine-grained examination of the effects of extraversion and conscientiousness on reported activity engagement-which we define as participation, time allocated, and affective experience-during 8 everyday activities. Data were obtained using a day reconstruction measure from a subgroup of participants in the 2012 Health and Retirement Study (HRS: N = 5,484; mean age = 67.98 years). We found mixed support for hypotheses suggesting that specific personality traits would be associated with activity participation, time allocated, and activity-affective experience. For example, extraverts were more likely to socialize and experienced higher socializing-related positive affect, but did not spend more time socializing. Results are discussed in light of the value of including personality in, and its contribution to, studies of activity engagement in later life. In addition, the need to acknowledge the complexity of the concept of activity engagement in future research is highlighted. © The Author 2016.

    Due to increased economic challenges in the management of hospitals head surgeons do not only need excellent surgical expertise but also significant management qualities. The personality of head surgeons should include authenticity, sincerity, fairness and the ability to cooperate. Visionary leadership, strategic thinking and strategic management of the personnel are further prerequisites for success. Besides good abilities in communication head surgeons need knowledge of the operating figures for interpretation. To keep up with the own capabilities time and self-management is essential. A survival as head surgeon is likely if these qualities and abilities exist.

    2016-01-01

    This study examined the relationship between flow experience and place identity, based on eudaimonistic identity theory (EIT) which prioritizes self-defining activities as important for an individual's identification of his/her goals, values, beliefs, and interests corresponding to one's own identity development or enhancement. This study focuses on place identity, the identity's features relating to a person's relation with her/his place. The study is also based on flow theory, according to which some salient features of an activity experience are important for happiness and well-being. Questionnaire surveys on Italian and Greek residents focused on their perceived flow and place identity in relation to their own specific local place experiences. The overall findings revealed that flow experience occurring in one's own preferred place is widely reported as resulting from a range of self-defining activities, irrespective of gender or age, and it is positively and significantly associated with one's own place identity. Such findings provide the first quantitative evidence about the link between flow experienced during meaningfully located self-defining activities and identity experienced at the place level, similarly to the corresponding personal and social levels that had been previously already empirically tested. Results are also discussed in terms of their implications for EIT's understanding and enrichment, especially by its generalization from the traditional, personal identity level up to that of place identity. More generally, this study has implications for maintaining or enhancing one's own place identity, and therefore people-place relations, by means of facilitating a person's flow experience within psychologically meaningful places.

  3. Retrival experience as an accurate indicator of person identification in line-ups

    Directory of Open Access Journals (Sweden)

    María José Contreras

    2011-07-01

    Full Text Available Responses in eyewitness identification of a person in a line-up may be based on two types of recovery experiences, remember and know experiences. Remember responses involve eyewitness identification of the target person as an episodic memory task, because it implies retrieving information about the target person in the place and at the time of the event. Know responses, in contrast, engage recognition based on familiarity or perceptual facilitation, that is, as a semantic memory task. To explore the relation between retrieval experiences and recognition accuracy, 86 participants took part in a recognition task with two conditions: one with an interpolated target absent line-up and the other only with the target present line-up. Accuracy of recognition and retrieval experience was measured. The results showed that, having previously participated in a target-absent line-up, increased omissions, while the number of hits decreased. Furthermore, participants’ know responses were associated to false recognition, whilst remember responses were associated to hits in recognition. Thus, asking eyewitnesses to inform about the kind of retrieval experience in which they based their recognition responses, may serve as a reliable indicator of accuracy in recognition. Future studies are needed to investigate whether this is also the case in natural settings.

    This study presents the theoretical background, development, and psychometric properties of the German and English versions of the Experience in Personal Social Systems Questionnaire (EXIS.pers). It assesses how the members of a personal social system experience their situation within that system. It is designed as a research tool for interventions in which only one member of the system participates (e.g., Family Constellation Seminars). The EXIS.pers was created to measure change on the individual level relating to one's own important personal social system. In Study 1, we used exploratory factor analysis (EFA) for latent variable identification of the original German EXIS.pers (n = 179). In Studies 2 and 3, we used confirmatory factor analysis (CFA) to examine the dimensionality of the German (n = 634) and English (n = 310) EXIS.pers. Internal consistencies and cross-cultural structural equivalence were assessed. EFA indicated that a four-factor model provided best fit for the German EXIS.pers. For both the German and English EXIS.pers, CFA provided the best fit for a five-factor bi-level model that included a general factor (Experience In Personal Social Systems) and four dimensions (Belonging, Autonomy, Accord, Confidence). Good internal consistencies, external associations, and cross-cultural structural equivalence were demonstrated. This study provides first evidence for the German and English EXIS.pers as an economical and reliable measure of an individual's experience within his or her personal social systems. © 2016 Family Process Institute.

    Personal floatation devices maintain either a semirecumbent flotation posture with the head and upper chest out of the water or a horizontal flotation posture with the dorsal head and whole body immersed. The contribution of dorsal head and upper chest immersion to core cooling in cold water was isolated when the confounding effect of shivering heat production was inhibited with meperidine (Demerol, 2.5 mg/kg). Six male volunteers were immersed four times for up to 60 min, or until esophageal temperature = 34 degrees C. An insulated hoodless dry suit or two different personal floatation devices were used to create four conditions: 1) body insulated, head out; 2) body insulated, dorsal head immersed; 3) body exposed, head (and upper chest) out; and 4) body exposed, dorsal head (and upper chest) immersed. When the body was insulated, dorsal head immersion did not affect core cooling rate (1.1 degrees C/h) compared with head-out conditions (0.7 degrees C/h). When the body was exposed, however, the rate of core cooling increased by 40% from 3.6 degrees C/h with the head out to 5.0 degrees C/h with the dorsal head and upper chest immersed (P immersed (approximately 10%). The exaggerated core cooling during dorsal head immersion (40% increase) may result from the extra heat loss affecting a smaller thermal core due to intense thermal stimulation of the body and head and resultant peripheral vasoconstriction. Dorsal head and upper chest immersion in cold water increases the rate of core cooling and decreases potential survival time.

    Nurses provide healthcare services to members of the adoption triad (AT; birth parents, adoptive parents, and the child) in a number of settings. However, nurses' perceptions of and interactions with members of the AT have not been investigated. This study describes the lived experiences of nurses and the care rendered to the AT using a descriptive phenomenological approach. In response to an invitation published in a national electronic newsletter, nurses were asked to submit narratives about their experiences in caring for members of the AT. Researchers coded 17 narratives using Colaizzi's phenomenological method. Four themes emerged from the texts: (1) Where the personal and professional selves meet ("I see so many issues from both sides"); (2) The paradox of adoption ("...an emotional rollercoaster"); (3) Unique contexts of adoptive families ("We all have a story"); and (4) Reframing nurses' perceptions surrounding adoption ("There are several areas we could improve"). Nurses often have a personal connection to adoption and this potentiates the care delivered to AT members. Serving as role models for their peers and advocates for a better understanding of the dynamics of relinquishment and placement, nurses can improve clinical practices for these patients. Themes reflected insights gained from both personal and professional roles and offer specific interventions that enhance care of the AT. Nursing education and practice guidelines should include care rendered to the AT.

  9. Cold-Hearted or Cool-Headed: Physical Coldness Promotes Utilitarian Moral Judgment

    2014-10-01

    Full Text Available In the current study, we examine the effect of physical coldness on personal moral dilemma judgment. Previous studies have indicated that utilitarian moral judgment—sacrificing a few people to achieve the greater good for others—was facilitated when: (1 participants suppressed an initial emotional response and deliberately thought about the utility of outcomes; (2 participants had a high-level construal mindset and focused on abstract goals (e.g., save many; or (3 there was a decreasing emotional response to sacrificing a few. In two experiments, we exposed participants to extreme cold or typical room temperature and then asked them to make personal moral dilemma judgments. The results of Experiment 1 indicated that coldness prompted utilitarian judgment, but the effect of coldness was independent from deliberate thought or abstract high-level construal mindset. As Experiment 2 revealed, coldness facilitated utilitarian judgment via reduced empathic feelings. Therefore, physical coldness did not affect the cool-headed deliberate process or the abstract high-level construal mindset. Rather, coldness biased people toward being cold-hearted, reduced empathetic concern about a sacrificed victim, and facilitated utilitarian moral judgments.

    We test whether adverse childhood experiences exposure to parental maltreatment and its indirect effect on health are associated with age 30 personality traits. We use rich longitudinal data from a large, representative cohort of young US Americans and exploit differences across siblings to control for the confounding influences of shared environmental and genetic factors. We find that maltreatment experiences are significantly and robustly associated with neuroticism, conscientiousness, and ...

    Paragangliomas of the head and neck and cranial base are typically benign, slow-growing tumors arising within the jugular foramen, middle ear, carotid bifurcation, or vagus nerve proper. The objective of this study was to provide a comprehensive characterization of our institutional experience with clinical management of these tumors and posit an algorithm for diagnostic evaluation and treatment. This was a retrospective cohort study of patients undergoing treatment for paragangliomas of the head and neck and cranial base at our institution from 2000-2017. Data on tumor location, catecholamine levels, and specific imaging modalities employed in diagnostic work-up, pre-treatment cranial nerve palsy, treatment modality, utilization of preoperative angiographic embolization, complications of treatment, tumor control and recurrence, and hereditary status (ie, succinate dehydrogenase mutations) were collected and summarized. The mean (SD) age of our cohort was 51.8 (±16.1) years with 123 (63.4%) female patients and 71 (36.6%) male patients. Catecholamine-secreting lesions were found in nine (4.6%) patients. Fifty-one patients underwent genetic testing, with mutations identified in 43 (20 SDHD , 13 SDHB, 7 SDHD , 1 SDHA, SDHAF2, and NF1 ). Observation with serial imaging, surgical extirpation, radiation, and stereotactic radiosurgery were variably employed as treatment approaches across anatomic subsites. An algorithmic approach to clinical management of these tumors, derived from our longitudinal institutional experience and current empiric evidence, may assist otolaryngologists, radiation oncologists, and geneticists in the care of these complex neoplasms. 4.

    The influence of head posture on movement paths of the incisal point (IP) and of the mandibular condyles during free open-close movements was studied. Ten persons, without craniomandibular or cervical spine disorders, participated in the study. Open close mandibular movements were recorded with the head in five postures, viz., natural head posture, forward head posture, military posture, and lateroflexion to the right and to the left side, using the Oral Kinesiologic Analysis System (OKAS-3D). This study showed that in a military head posture, the opening movement path of the incisal point is shifted anteriorly relative to the path in a natural head posture. In a forward head posture, the movement path is shifted posteriorly whereas during lateroflexion, it deviates to the side the head has moved to. Moreover, the intra-articular distance in the temporomandibular joint during closing is smaller with the head in military posture and greater in forward head posture, as compared to the natural head posture. During lateroflexion, the intra-articular distance on the ipsilateral side is smaller. The influence of head posture upon the kinematics of the mandible is probably a manifestation of differences in mandibular loading in the different head postures.

    During life, many personal changes occur. These include changing house, school, work, and even friends and partners. However, the daily experience shows clearly that, in some situations, subjects are unable to change even if they want to. The recent advances in psychology and neuroscience are now providing a better view of personal change, the change affecting our assumptive world: (a) the focus of personal change is reducing the distance between self and reality (conflict); (b) this reduction is achieved through (1) an intense focus on the particular experience creating the conflict or (2) an internal or external reorganization of this experience; (c) personal change requires a progression through a series of different stages that however happen in discontinuous and non-linear ways; and (d) clinical psychology is often used to facilitate personal change when subjects are unable to move forward. Starting from these premises, the aim of this paper is to review the potential of virtuality for enhancing the processes of personal and clinical change. First, the paper focuses on the two leading virtual technologies - augmented reality (AR) and virtual reality (VR) - exploring their current uses in behavioral health and the outcomes of the 28 available systematic reviews and meta-analyses. Then the paper discusses the added value provided by VR and AR in transforming our external experience by focusing on the high level of personal efficacy and self-reflectiveness generated by their sense of presence and emotional engagement. Finally, it outlines the potential future use of virtuality for transforming our inner experience by structuring, altering, and/or replacing our bodily self-consciousness. The final outcome may be a new generation of transformative experiences that provide knowledge that is epistemically inaccessible to the individual until he or she has that experience, while at the same time transforming the individual's worldview.

    Very few women assume the role of head athletic trainer (AT). Reasons for this disparity include discrimination, motherhood, and a lack of interest in the position. However, data suggest that more women seek the head AT position in National Collegiate Athletic Association Division II and III settings. To examine the barriers female ATs face as they transition to the role of head AT. Qualitative study. Divisions II and III. In total, 77 female ATs participated in our study. Our participants (38 ± 9 years old) were employed as head ATs at the Division II or III level. We conducted online interviews with all participants. They journaled their reflections to a series of open-ended questions pertaining to their experiences as head ATs. Data were analyzed following a general inductive approach. Credibility was secured by peer review and researcher triangulation. Organizational and personal factors emerged as the 2 major themes that described challenges for women assuming the role of the head AT. Organizational barriers were defined by gender stereotyping and the "good old boys" network. Personal influences included a lack of leadership aspirations, motherhood and family, and a lack of mentors. Female ATs working in Divisions II or III experienced similar barriers to assuming the role of the head AT as those working in the Division I setting. Stereotyping still exists within collegiate athletics, which limits the number of women in higher-ranking positions; however, a lack of desire to assume a higher position and the desire to balance work and home inhibit some women from moving up.

    A large body of evidence, including longitudinal analyses of personality change, suggests that core personality traits are predominantly stable after age 30. To our knowledge, no study has demonstrated changes in personality in healthy adults after an experimentally manipulated discrete event. Intriguingly, double-blind controlled studies have shown that the classic hallucinogen psilocybin occasions personally and spiritually significant mystical experiences that predict long-term changes in behaviors, attitudes and values. In the present report we assessed the effect of psilocybin on changes in the five broad domains of personality - Neuroticism, Extroversion, Openness, Agreeableness, and Conscientiousness. Consistent with participant claims of hallucinogen-occasioned increases in aesthetic appreciation, imagination, and creativity, we found significant increases in Openness following a high-dose psilocybin session. In participants who had mystical experiences during their psilocybin session, Openness remained significantly higher than baseline more than 1 year after the session. The findings suggest a specific role for psilocybin and mystical-type experiences in adult personality change.

    Patient education (PE) is a core treatment of osteoarthritis (OA) with the aim to increase persons' knowledge, self-efficacy, and empowerment. To describe person's various experiences of learning processes in PE for OA. Phenomenography. Semi-structured interviews were performed with the same persons, pre- (11) and post- (9) education. Various experiences on learning processes were found and were described in an outcome space. Achieving knowledge describes self-regulated learning and strongly relates to Control, which describes a high order cognitive learning skill, and minor to Confirm, which describes a cognitive learning skill based on recognition and application. Receiving knowledge describes the expectancy of learning regulated from the educator and strongly relates to Comply, which describes a low-order cognitive learning skill, and minor to Confirm. Different experiences of motivation and learning impact on persons' learning processes which, in turn, influence the persons' capability to accomplish self-efficacy and empowerment. The outcome space may serve as a basis for discussions between healthcare educators involved in PE to better understand what learning implies and to develop PE further.

    It is a challenge to promote exercise among older persons. Knowledge is needed regarding the maintenance of exercise aiming at preventing falls and promoting health and well-being in older persons. This descriptive study used a qualitative inductive approach to describe older persons' experiences of a fall-preventive, home-based exercise program with support for behavioral change. Semi-structured interviews were conducted with 12 elderly persons aged 75 years or older, and a qualitative content analysis was performed. Four categories emerged: facilitators of performing exercise in everyday life, the importance of support, perceived gains from exercise, and the existential aspects of exercise. With support from physiotherapists (PTs), home-based exercise can be adapted to individual circumstances in a meaningful way. Including exercises in everyday life and daily routines could support the experience of being stronger, result in better physical functioning, and give hope for an extended active life in old age.

US otolaryngology training programs. Faculty and trainees in US otolaryngology training programs. A 14-item survey to assess the prevalence of the experience of shame and the attitudes toward use of shame in otolaryngology residency training was sent to all otolaryngology-head and neck surgery program directors for distribution among their respective faculty and resident cohorts. A total of 267 responses were received (women, 24.7%; men, 75.3%): 42.7% of respondents were trainees; 7.0% of trainees thought that shame was a necessary/effective tool, compared with 11.4% of faculty; 50% of respondents felt that they had been personally shamed during residency; and 69.9% of respondents had witnessed another trainee being shamed during residency training. Trainees were most commonly shamed in the operating room (78.4%). Otolaryngology faculty members did the shaming 95.1% of the time. Although shaming prompted internal reflection/self-improvement in 57.4% of trainees, it also caused loss of self-confidence in 52.5%. Trainees who had been shamed were more likely to view shame as an appropriate educational tool (P Otolaryngology—Head and Neck Surgery Foundation 2015.

    Does person perception--the impressions we form from watching others--hold clues to the mental states of people engaged in cognitive tasks? We investigated this with a two-phase method: In Phase 1, participants searched on a computer screen (Experiment 1) or in an office (Experiment 2); in Phase 2, other participants rated the searchers' video-recorded behavior. The results showed that blind raters are sensitive to individual differences in search proficiency and search strategy, as well as to environmental factors affecting search difficulty. Also, different behaviors were linked to search success in each setting: Eye movement frequency predicted successful search on a computer screen; head movement frequency predicted search success in an office. In both settings, an active search strategy and positive emotional expressions were linked to search success. These data indicate that person perception informs cognition beyond the scope of performance measures, offering the potential for new measurements of cognition that are both rich and unobtrusive.

    Head motion reduces data quality of neuroimaging data. In three functional magnetic resonance imaging (MRI) experiments we demonstrate that people make less head movements under task than resting-state conditions. In Experiment 1, we observed less head motion during a memory encoding task than during the resting-state condition. In Experiment 2, using publicly shared data from the UCLA Consortium for Neuropsychiatric Phenomics LA5c Study, we again found less head motion during several active task conditions than during a resting-state condition, although some task conditions also showed comparable motion. In the healthy controls, we found more head motion in men than in women and more motion with increasing age. When comparing clinical groups, we found that patients with a clinical diagnosis of bipolar disorder, or schizophrenia, move more compared to healthy controls or patients with ADHD. Both these experiments had a fixed acquisition order across participants, and we could not rule out that a first or last scan during a session might be particularly prone to more head motion. Therefore, we conducted Experiment 3, in which we collected several task and resting-state fMRI runs with an acquisition order counter-balanced. The results of Experiment 3 show again less head motion during several task conditions than during rest. Together these experiments demonstrate that small head motions occur during MRI even with careful instruction to remain still and fixation with foam pillows, but that head motion is lower when participants are engaged in a cognitive task. These finding may inform the choice of functional runs when studying difficult-to-scan populations, such as children or certain patient populations. Our findings also indicate that differences in head motion complicate direct comparisons of measures of functional neuronal networks between task and resting-state fMRI because of potential differences in data quality. In practice, a task to reduce head motion

    The federal Early Head Start program provides a relevant context to examine families' experiences with stress since participants qualify on the basis of poverty and risk. Building on previous research that has shown variations in demographic and economic risks even among qualifying families, we examined possible variations in families' perceptions of stress. Family, parent, and child data were collected to measure stressors and risk across a variety of domains in families' everyday lives, primarily from self-report measures, but also including assay results from child cortisol samples. A cluster analysis was employed to examine potential differences among groups of Early Head Start families. Results showed that there were three distinct subgroups of families, with some families perceiving that they experienced very high levels of stress while others perceived much lower levels of stress despite also experiencing poverty and heightened risk. These findings have important implications in that they provide an initial step toward distinguishing differences in low-income families' experiences with stress, thereby informing interventions focused on promoting responsive caregiving as a possible mechanism to buffer the effects of family and social stressors on young children. © 2017 Michigan Association for Infant Mental Health.

    The purpose of this study was to assess the possible effect of recalled traumatic experiences, perceived parental rearing styles, and family parameters on the occurrence of borderline personality disorder (BPD) versus other personality disorders (other-PDs). A total of 88 adult outpatients with personality disorders completed the Traumatic Antecedents Questionnaire and the Egna Minnen av Barndoms Uppfostran, which measures perceptions regarding parental rearing. Results indicated that incidence of traumatic childhood experiences was higher among those in the BPD group compared to those in the other-PD group. Firstborns were less likely to carry a diagnosis of BPD over other-PDs. Also, significantly more BPD compared to other-PD patients reported being the father's favorite child over siblings. Results suggest that traumatic experiences, birth order, and family interactions in the presence of siblings seem to differentially affect the formation of borderline diagnosis compared to other-PDs. Limitations and clinical implications of the study are discussed in detail.

    Concepts of recovery increasingly inform the development and delivery of mental health services internationally. In the UK recent policy advocates the application of recovery concepts to the treatment of personality disorders. However diagnosis and understanding of personality disorders remains contested, challenging any assumption that mainstream recovery thinking can be directly translated into personality disorders services. In a qualitative interview-based study understandings of recovery were explored in extended, in-depth interviews with six people purposively sampled from a specialist personality disorders' service in the UK. An interpretive, collaborative approach to research was adopted in which university-, clinical- and service user (consumer) researchers were jointly involved in carrying out interviews and analysing interview data. Findings suggested that recovery cannot be conceptualised separately from an understanding of the lived experience of personality disorders. This experience was characterised by a complexity of ambiguous, interrelating and conflicting feelings, thoughts and actions as individuals tried to cope with tensions between internally and externally experienced worlds. Our analysis was suggestive of a process of recovering or, for some, discovering a sense of self that can safely coexist in both worlds. We conclude that key facilitators of recovery - positive personal relationships and wider social interaction - are also where the core vulnerabilities of individuals with lived experience of personaility disorders can lie. There is a role for personality disorders services in providing a safe space in which to develop positive relationships. Through discursive practice within the research team understandings of recovery were co-produced that responded to the lived experience of personality disorders and were of applied relevance to practitioners.

    Most of the existing studies on musical practice are concerned with instrumentalists only. Since singers are seldom considered in research, the present study is based on an online-sample of amateur vocal students (N = 120; 92 female, 28 male). The study investigated the correlations between personality traits, flow-experience and several aspects of practice characteristics. Personality was represented by the three personality dimensions extraversion, neuroticism and psychoticism, assessed by Eysenck's Personality Profiler as well as the trait form of the Positive and Negative Affect Schedule. 'Flow-experience,' 'self-congruence' and 'fear of losing control over concentration,' assessed by the Practice Flow Inventory, served as variables for flow-experience. The practice motivation was measured by the Practice Motivation Questionnaire in four categories ('self,' 'group,' 'audience,' 'teacher'). In addition, the Practice Behavior Questionnaire was used to provide an insight into the practice situation and behavior of singing students. The results show significant correlations: participants with high extraversion-scores experience significantly more flow than less extraverted persons, whereas lesser flow-experience seems to be related to high neuroticism-scores. Nevertheless, there is no influence in flow-experience concerning singing style ('classical' or 'popular'). The longer the practicing time, the more likely students are to achieve flow-experience. However, older singers tend to have less flow-experience. Consequently, singers seem to differ in their personality and practice behavior compared to other musicians. Most of the findings show that having control over one's instrument is decisive for achieving a performance of high quality, especially for singers. On the other hand, certainty in handling an instrument is essential to arouse a flow-feeling. However, flow-experience seems to be common mainly with amateur singers. In conclusion, this offers a starting

    Forbes, G B

    2001-12-01

    The motives, family experiences, and personality characteristics of 341 college students with and without tattoos or piercings were studied. Participants completed Lippa's 1991 measures of the Big Five personality factors, a shortened version of the Body Cathexis Scale, a series of questions about their childhood experiences, and questions about risk-taking behaviors. In addition, reasons to have or not have body modifications and the perceptions of people with body modifications were investigated. Of the 116 men and 186 women, 25% and 33%, respectively, had at least one tattoo or body piercing. There were very few differences in the childhood experiences or personality characteristics of people with or without body modifications. Although people with body modifications did not differ from people without modifications on the Big Five personality measures, people without modifications perceived people with modifications as much different from themselves on these measures. These results indicate that tattoos and piercings in college students are associated with significantly more risk-taking behavior, greater use of alcohol and marijuana, and less social conformity. However, the traditional stereotype that body modifications are indicators of social or personal pathology does not describe contemporary college students.

    At current state, although robotics technology has been immensely developed, the uncertainty to completely engage in human-robot interaction is still growing among people. Many current studies then started to concern about human factors that might influence human's likability like human's personality, and found that compatibility between human's and robot's personality (expressions of personality characteristics) can enhance human's likability. However, it is still unclear whether specific means and strategy of robot's nonverbal behaviours enhances likability from human with different personality traits and whether there is a relationship between robot's nonverbal behaviours and human's likability based on human's personality. In this study, we investigated and focused on the interaction via gaze and head nodding behaviours (mutual gaze convergence and head nodding synchrony) between introvert/extravert participants and robot in two communication strategies (Backchanneling and Turn-taking). Our findings reveal that the introvert participants are positively affected by backchanneling in robot's head nodding behaviour, which results in substantial head nodding synchrony whereas the extravert participants are positively influenced by turn-taking in gaze behaviour, which leads to significant mutual gaze convergence. This study demonstrates that there is a relationship between robot's nonverbal behaviour and human's likability based on human's personality.

    2013-01-01

    After an introductory course in experiential-integrative psychotherapy, 21 graduate students provided personal narratives of their experiences, which were analyzed using the grounded theory method. Results produced 37 hierarchically organized experiences, revealing that students perceived multiple changes in both professional (i.e., skill acquisition and learning related to the therapeutic process) and personal (i.e., self growth in a more private sphere) domains. Analysis also highlighted key areas of difficulties in training. By adding the personal accounts of graduate trainees, this study enriches and extends Pascual-Leone et al.'s (2012) findings on undergraduates' experiences, raising the number of cases represented in the model to 45. Findings confirm the model of novice trainee experiences while highlighting the unique experiences of undergraduate vs. graduate trainees.

    Full Text Available This paper examines the role of interviewers' experience, attitudes, personality traits and inter-personal skills in determining survey co-operation, conditional on contact. We take the perspective that these characteristics influence interviewers' behaviour and hence influence the doorstep interaction between interviewer and sample member. Previous studies of the association between doorstep behaviour and co-operation have not directly addressed the role of personality traits and inter-personal skills and most have been based on small samples of interviewers. We use a large sample of 842 face-to-face interviewers working for a major survey institute and analyse co-operation outcomes for over 100,000 cases contacted by those interviewers over a 13-month period. We find evidence of effects of experience, attitudes, personality traits and inter-personal skills on co-operation rates. Several of the effects of attitudes and inter-personal skills are explained by differences in experience, though some independent effects remain. The role of attitudes, personality and skills seems to be greatest for the least experienced interviewers.

    1988-01-01

    MR imaging has been shown to be more sensitive and specific than planar scintigraphy for avascular necrosis (AVN) of the femoral head. However, experience with single photon emission CT (SPECT) is limited. The authors retrospectively compared 1.5-T MR imaging with SPECT in 14 patients with suspected femoral head AVN. Agreement between MR imaging and SPECT was present in 24 femurs, 14 normal and ten with AVN. MR imaging showed changes of AVN in the remaining four femoral heads. Of these, one was normal and the other three inconclusive for AVN by SPECT. The authors conclude that MR imaging is superior to SPECT for the evaluation of AVN of the hip

  3. Does Transnational Experience Constrain Religiosity? Korean Evangelical Women’s Discourse on LGBT Persons

    Directory of Open Access Journals (Sweden)

    Gowoon Jung

    2016-10-01

    Full Text Available A large literature studies the views and discourses of Western, and especially American, conservative Christians with respect to homosexuality; only a few examine the discourse of Christians in non-Western countries, and none focuses on non-Western Christians with advanced, overseas education and careers. This paper examines the discourse of South Korean Evangelical women with overseas, educational or career experiences. I draw on 15 in-depth interviews with current and former members of a Seoul-based, Evangelical mega-church. Transnational, evangelical women show comparatively mild-minded and tolerant views toward homosexuality and LGBT persons. The women illustrated two pathways to reconcile their conflicting beliefs in conservative religion and human rights: first, the values of equity and meritocracy; and second, personal contacts with LGBT persons. This study suggests that for transnational migrants, traditional religiosity is challenged and constrained by sustained experiences in liberal, pluralistic societies.

  4. The Relation Between Supervisors' Big Five Personality Traits and Employees' Experiences of Abusive Supervision.

    2016-01-01

    The present study investigates the relation between supervisors' personality traits and employees' experiences of supervisory abuse, an area that - to date - remained largely unexplored in previous research. Field data collected from 103 supervisor-subordinate dyads showed that contrary to our expectations supervisors' agreeableness and neuroticism were not significantly related to abusive supervision, nor were supervisors' extraversion or openness to experience. Interestingly, however, our findings revealed a positive relation between supervisors' conscientiousness and abusive supervision. That is, supervisors high in conscientiousness were more likely to be perceived as an abusive supervisor by their employees. Overall, our findings do suggest that supervisors' Big Five personality traits explain only a limited amount of the variability in employees' experiences of abusive supervision.

  5. The Relationship Between Personality Traits, Flow-Experience, and Different Aspects of Practice Behavior of Amateur Vocal Students

    Most of the existing studies on musical practice are concerned with instrumentalists only. Since singers are seldom considered in research, the present study is based on an online-sample of amateur vocal students (N = 120; 92 female, 28 male). The study investigated the correlations between personality traits, flow-experience and several aspects of practice characteristics. Personality was represented by the three personality dimensions extraversion, neuroticism and psychoticism, assessed by Eysenck’s Personality Profiler as well as the trait form of the Positive and Negative Affect Schedule. ‘Flow-experience,’ ‘self-congruence’ and ‘fear of losing control over concentration,’ assessed by the Practice Flow Inventory, served as variables for flow-experience. The practice motivation was measured by the Practice Motivation Questionnaire in four categories (‘self,’ ‘group,’ ‘audience,’ ‘teacher’). In addition, the Practice Behavior Questionnaire was used to provide an insight into the practice situation and behavior of singing students. The results show significant correlations: participants with high extraversion-scores experience significantly more flow than less extraverted persons, whereas lesser flow-experience seems to be related to high neuroticism-scores. Nevertheless, there is no influence in flow-experience concerning singing style (‘classical’ or ‘popular’). The longer the practicing time, the more likely students are to achieve flow-experience. However, older singers tend to have less flow-experience. Consequently, singers seem to differ in their personality and practice behavior compared to other musicians. Most of the findings show that having control over one’s instrument is decisive for achieving a performance of high quality, especially for singers. On the other hand, certainty in handling an instrument is essential to arouse a flow-feeling. However, flow-experience seems to be common mainly with amateur singers

Retrospective review of patients referred for PEG placement from 2003 to 2005. Endoscopic Surgery in Section of General and Thoracic Surgery, Faculty of Medicine and Surgery, Palermo, Italy. A total of 50 patients, 11 women and 39 men, referred our Section for PEG placement. Indications for PEG placement included various neurologic impairment (82%), oesophageal non-operable cancer (6%), cardia non-operable cancer (4%), cerebrovascular accident (2%), anorexia (2%), pharyngeal esophageal obstruction (2%), head and neck cancer (2%). All patients received preoperative antibiotics as short-term profilaxis. 51 PEGs were positioned in 50 patients. No major complications were registered; 45 patients (90%) were alive at 1 year follow-up and no mortality procedure-related was registered. Percutaneous endoscopic gastrotomy removal had been performed on 2 patients as end-point of treatment, and 43 patients continued to have PEGs in use at 2006. Outpatients PEG placement using conscious sedation is a safe and effective method for providing enteral nutrition. This technique constitutes the gold standard treatment for enteral nutrition in patients with neurologic impairment or as prophylactic in patients affected by head and neck cancer who needs demolitive surgery. Patients should be carefully assessed, and discussion with the patient and their families should be held to determine that the patient is an appropriate candidate. The Authors feel prophylactic antibiotics lessened the incidence of cutaneous perigastrostomy infection.

    For some time, disability researchers have shown a growing interest in personal experiences of disability. To some extent this interest can be understood as a response to the growing support for an emancipatory approach in disability research and the awareness that people with disabilities often have been deprived of their opportunities to speak for themselves. A striking characteristic of the studies of personal experiences is a lack of analysis and methodological discussions. It is argued t...

    Full Text Available Personality disorders (PDs are marked by significant disturbances in the way of experiencing oneself, others and the world around. Yet there is paucity of research on the nature of emotional experiences in these disorders. The aim of this study was to examine whether and how emotional experience of individuals with ten distinct forms of PDs distinguished in DSM differs from those without PDs. The study was conducted via the Internet on a large nonclinical sample (N = 3509. Participants were administered a PDs measure and a performance task assessing three features of emotional experiences: emotional sensitivity, the valence of experienced emotions and the profile of five components constituting an emotion. As predicted, PDs sufferers experienced emotions differently from controls. Results demonstrated that individuals with all PDs were more receptive to emotional elicitation and displayed higher negative emotionality and a deficiency in the affective component of experienced emotions.

    2018-01-01

    Food allergies present numerous challenges to coping in everyday life. Even simple things like planning a lunch with a friend can be stressful for people with food allergies. But are some people more adversely impacted by having a food allergy than other people? This paper addressed this question by investigating whether individual differences in the Big Five personality traits (neuroticism, extraversion, openness, agreeableness, and conscientiousness) are related to food allergy-related problems in everyday life among adults with food allergies. Participants were 108 adults (85% female; mean age = 40.2; age range 18–87) with a physician-diagnosed food allergy [most commonly to gluten (54.6%), peanuts (21.3%), cow's milk (16.7%), and shellfish/seafood (16.7%)]. Participants completed an initial online survey that measured demographics, food allergy information, and personality traits using the Big Five Inventory (John et al., 1991). For 2 weeks, participants completed a daily online survey that queried the occurrence of 25 food allergy issues that day and participants' overall stress and mood that day. Neuroticism did not predict more frequent allergy issues or greater stress/poorer mood on days with more allergy issues. Instead, higher openness to experience predicted a range of issues including going hungry because there is no safe food available, problems finding suitable foods when grocery shopping, feeling anxious at social occasions involving food, being excluded, and feeling embarrassed and poorly understood about their food allergy. Conscientious people were less embarrassed or self-conscious about their food allergy, but they had more problems eating out, and their positive mood was more impaired by allergy issues than their less conscientious peers. Extraversion and agreeableness played minor roles. Personality testing can identify people that may have difficulty living with food allergies–such as those higher in openness to experience.

    Direct-to-consumer (DTC) personal genotyping services are beginning to be adopted by educational institutions as pedagogical tools for learning about human genetics. However, there is little known about student reactions to such testing. This study investigated student experiences and attitudes towards DTC personal genome testing. Individual interviews were conducted with students who chose to undergo personal genotyping in the context of an elective genetics course. Ten medical and graduate students were interviewed before genotyping occurred, and at 2 weeks and 6 months after receiving their genotype results. Qualitative analysis of interview transcripts assessed the expectations and experiences of students who underwent personal genotyping, how they interpreted and applied their results; how the testing affected the quality of their learning during the course, and what were their perceived needs for support. Students stated that personal genotyping enhanced their engagement with the course content. Although students expressed skepticism over the clinical utility of some test results, they expressed significant enthusiasm immediately after receiving their personal genetic analysis, and were particularly interested in results such as drug response and carrier testing. However, few reported making behavioral changes or following up on specific results through a healthcare provider. Students did not report utilizing genetic counseling, despite feeling strongly that the 'general public' would need these services. In follow-up interviews, students exhibited poor recall on details of the consent and biobanking agreements, but expressed little regret over their decision to undergo genotyping. Students reported mining their raw genetic data, and conveyed a need for further consultation support in their exploration of genetic variants. Personal genotyping may improve students' self-reported motivation and engagement with course material. However, consultative support that

    When speaking or singing, vocalists often move their heads in an expressive fashion, yet the influence of emotion on vocalists' head motion is unknown. Using a comparative speech/song task, we examined whether vocalists' intended emotions influence head movements and whether those movements influence the perceived emotion. In Experiment 1, vocalists were recorded with motion capture while speaking and singing each statement with different emotional intentions (very happy, happy, neutral, sad, very sad). Functional data analyses showed that head movements differed in translational and rotational displacement across emotional intentions, yet were similar across speech and song, transcending differences in F0 (varied freely in speech, fixed in song) and lexical variability. Head motion specific to emotional state occurred before and after vocalizations, as well as during sound production, confirming that some aspects of movement were not simply a by-product of sound production. In Experiment 2, observers accurately identified vocalists' intended emotion on the basis of silent, face-occluded videos of head movements during speech and song. These results provide the first evidence that head movements encode a vocalist's emotional intent and that observers decode emotional information from these movements. We discuss implications for models of head motion during vocalizations and applied outcomes in social robotics and automated emotion recognition. (c) 2016 APA, all rights reserved).

    Research suggests that women do not pursue leadership positions in athletic training due to a variety of reasons, including family challenges, organizational constraints, and reluctance to hold the position. The literature has been focused on the National Collegiate Athletic Association Division I setting, limiting our full understanding. To examine factors that help women as they worked toward the position of head athletic trainer. Qualitative study. Divisions II and III. Seventy-seven women who were employed as head athletic trainers at the Division II or III level participated in our study. Participants were 38 ± 9 (range = 24-57) years old and had an average of 14 ± 8 (range = 1-33) years of athletic training experience. We conducted online interviews. Participants journaled their reflections to a series of open-ended questions pertaining to their experiences as head athletic trainers. Data were analyzed using a general inductive approach. Credibility was secured by peer review and researcher triangulation. Three organizational facilitators emerged from the data, workplace atmosphere, mentors, and past work experiences. These organizational factors were directly tied to aspects within the athletic trainer's employment setting that allowed her to enter the role. One individual-level facilitator was found: personal attributes that were described as helpful for women in transitioning to the role of the head athletic trainer. Participants discussed being leaders and persisting toward their career goals. Women working in Divisions II and III experience similar facilitators to assuming the role of head athletic trainer as those working in the Division I setting. Divisions II and III were viewed as more favorable for women seeking the role of head athletic trainer, but like those in the role in the Division I setting, women must have leadership skills.

    From the findings obtained by means of the interviews of women living with borderline personality disorder, it was evident that there were childhood experiences of living in an unsafe space, related to unhealthy family dynamics, boundary violations and educational challenges. They experienced chronic feelings of emptiness in their relationships with the self. They also presented with a pattern of unstable interpersonal relationships and compromised mental health, which was apparent through the early onset of mental problems, emotional upheaval, looking for emotional escape and having different trigger factors. Lastly, all these women yearned for facilitated mental health.

    2013-10-01

    Personal health budgets were piloted in the English National Health Service between 2009 and 2012. Semi-structured interviews with a sub-sample of early budget holders aimed to explore their experiences of receiving and using a budget. Over 2000 people from 20 pilot sites were recruited to a multi-method evaluation of the personal health budget pilots. A sub-sample of 58 people was selected for qualitative interviews three months after the offer of a budget; 52 were re-interviewed six months later. The purposively selected sample reflected a range of health conditions, locality, age and gender. Personal health budgets were reported to have positive impacts on health, health care and relatives/family. Benefits often extended beyond the condition for which the budget had been awarded. However, interviewees rarely knew the level of their budget; some reported difficulty in agreeing acceptable uses for their budget; and delays could occur in procuring chosen services or equipment. Patients' experiences offer valuable insights for the roll-out of personal health budgets beyond the pilot phase. Flexibility in how budgets are used may allow maximum benefits to be derived. Clear information about what budgets can and cannot be used for, with suggestions offered, will be useful. People with newly diagnosed or recent sudden onset conditions may need more help to plan their support, but all budget holders are likely to benefit from regular contact with staff for reassurance and continued motivation.

  3. Heading and head injuries in soccer.

    Kirkendall, D T; Jordan, S E; Garrett, W E

    In the world of sports, soccer is unique because of the purposeful use of the unprotected head for controlling and advancing the ball. This skill obviously places the player at risk of head injury and the game does carry some risk. Head injury can be a result of contact of the head with another head (or other body parts), ground, goal post, other unknown objects or even the ball. Such impacts can lead to contusions, fractures, eye injuries, concussions or even, in rare cases, death. Coaches, players, parents and physicians are rightly concerned about the risk of head injury in soccer. Current research shows that selected soccer players have some degree of cognitive dysfunction. It is important to determine the reasons behind such deficits. Purposeful heading has been blamed, but a closer look at the studies that focus on heading has revealed methodological concerns that question the validity of blaming purposeful heading of the ball. The player's history and age (did they play when the ball was leather and could absorb significant amounts of water), alcohol intake, drug intake, learning disabilities, concussion definition and control group use/composition are all factors that cloud the ability to blame purposeful heading. What does seem clear is that a player's history of concussive episodes is a more likely explanation for cognitive deficits. While it is likely that the subconcussive impact of purposeful heading is a doubtful factor in the noted deficits, it is unknown whether multiple subconcussive impacts might have some lingering effects. In addition, it is unknown whether the noted deficits have any affect on daily life. Proper instruction in the technique is critical because if the ball contacts an unprepared head (as in accidental head-ball contacts), the potential for serious injury is possible. To further our understanding of the relationship of heading, head injury and cognitive deficits, we need to: learn more about the actual impact of a ball on the

    Person-centred care is internationally recognised as best practice for the care of people with dementia. Personal information documents for people with dementia are proposed as a way to support person-centred care in healthcare settings. However, there is little research about how they are used in practice. The aim of this study was to analyse healthcare staff 's perceptions and experiences of using personal information documents, mainly Alzheimer's Society's 'This is me', for people with dementia in healthcare settings. The method comprised a secondary thematic analysis of data from a qualitative study, of how a dementia awareness initiative affected care for people with dementia in one healthcare organisation. The data were collected through 12 focus groups (n = 58 participants) and 1 individual interview, conducted with a range of healthcare staff, both clinical and non-clinical. There are four themes presented: understanding the rationale for personal information documents; completing personal information documents; location for personal information documents and transfer between settings; impact of personal information documents in practice. The findings illuminated how healthcare staff use personal information documents in practice in ways that support person-centred care. Practical issues about the use of personal information documents were revealed and these may affect the optimal use of the documents in practice. The study indicated the need to complete personal information documents at an early stage following diagnosis of dementia, and the importance of embedding their use across care settings, to support communication and integrated care.

    Clozapine is an atypical antipsychotic medicine which can cause significant side-effects. It is often prescribed off-license in severe cases of borderline personality disorder contrary to national treatment guidelines. Little is known about the experiences of those who take clozapine for borderline personality disorder. We explored the lived-experience of women in secure inpatient care who were prescribed clozapine for borderline personality disorder. Adult females ( N  = 20) participated in audio-taped semi-structured interviews. Transcripts were subject to thematic analysis. The central themes related to evaluation, wellbeing, understanding and self-management; for many, their subjective wellbeing on clozapine was preferred to prior levels of functioning and symptomatology, sometimes profoundly so. The negative and potentially adverse effects of clozapine were explained as regrettable but relatively unimportant. When psychological interventions are, at least initially, ineffective then clozapine treatment is likely to be evaluated positively by a group of women with borderline personality disorder in secure care despite the potential disadvantages.

    Full Text Available Purpose. The purpose of this study was to empirically analyze the sports background, personality dimensions, attitudes, and social competencies of adult head coaches and young assistant coaches involved in the German Einfach Fußball (Just Soccer program, which promotes the participation of pupils with intellectual disabilities in soccer/sports and society. Methods. The study recruited 28 head coaches and 29 assistant coaches who completed a questionnaire battery of standardized instruments (NEO Five-Factor Inventory, Interpersonal Reactivity Index, Social Self-Efficacy as well as self-developed instruments. Analysis of the data involved descriptive and inferential statistical procedures. A descriptive comparison of the assistant coaches with a normative sample of males aged 16-20 years was performed. Results. The head coaches were found with little soccer/sports experience with persons with disabilities prior to participation in the Just Soccer program. However, the majority were familiar with these persons through personal/vocational contacts. Overall, the head coaches were differentiated by formal coaching levels and playing backgrounds, with very few holding any additional formal qualifications in special education. The assistant coaches presented below average scores in the analyzed five personality dimensions when compared with the normative sample. Their attitudes and social competencies did not change during their 8-month involvement in Just Soccer. Conclusions. The findings highlight the important role of the coaching staff in the success of the Just Soccer program. Coaches involved in such activities should be familiarized with needs of people with disabilities, be stress-resistant, and possess a balanced set of personality traits. In addition, the results suggest that such individuals should be coaches/players from conventional soccer clubs instead of special school physical education teachers.

  7. Overt head movements and persuasion: a self-validation analysis.

    The authors report 3 experiments that examine a new mechanism by which overt head movements can affect attitude change. In each experiment, participants were induced to either nod or to shake their heads while listening to a persuasive message. When the message arguments were strong, nodding produced more persuasion than shaking. When the arguments were weak, the reverse occurred. These effects were most pronounced when elaboration was high. These findings are consistent with the "self-validation" hypothesis that postulates that head movements either enhance (nodding) or undermine (shaking) confidence in one's thoughts about the message. In a 4th experiment, the authors extended this result to another overt behavior (writing with the dominant or nondominant hand) and a different attitude domain (self-esteem).

    PURPOSE: We investigated whether retinis pigmentosa (RP) patients with residual visual field of < 100 degrees could perceive heading from optic flow. METHODS: Four RP patients and four age-matched normally sighted control subjects viewed displays simulating an observer walking over a ground. In experiment 1, subjects viewed either the entire display with free fixation (full-field condition) or through an aperture with a fixation point at the center (aperture condition). In experiment 2, patients viewed displays of different durations. RESULTS: RP patients' performance was comparable to that of the age-matched control subjects: heading judgment was better in the full-field condition than in the aperture condition. Increasing display duration from 0.5 s to 1 s improved patients' heading performance, but giving them more time (3 s) to gather more visual information did not consistently further improve their performance. CONCLUSIONS: RP patients use active scanning eye movements to compensate for their visual field loss in heading perception; they might be able to gather sufficient optic flow information for heading perception in about 1 s.

    Can we assess individual differences in the extent to which a person perceives the rubber-hand illusion on the basis of self-reported experiences? In this research, we develop such an instrument using Rasch-type models. In our conception, incorporating an object (e.g., a rubber hand) into one's body image requires various sensorimotor and cognitive processes. The extent to which people can meet these requirements thus determines how intensely people experience and, simultaneously, describe the illusion. As a consequence, individual differences in people's susceptibility to the rubber-hand illusion can be determined by inspecting reports of their personal experiences. The proposed model turned out to be functional in its capability to predict self-reports of people's experiences and to reliably assess individual differences in susceptibility to the illusion. Regarding validity, we found a small, but significant, correlation between individual susceptibility and proprioceptive drift. Additionally, we found that asynchrony, and tapping rather than stroking the fingers constrain the experience of the illusion. Copyright © 2012 Elsevier B.V. All rights reserved.

    Section III of DSM-5 includes an alternative model for personality disorders comprising five higher-order pathological personality traits, four of which resemble domains from the Big Five/Five-Factor Model of Personality (FFM). There has, however, been considerable debate regarding the association of FFM Openness-to-Experience/Intellect (OE/I) with DSM-5 Psychoticism and Schizotypal Personality Disorder (STPD). The authors identify several limitations in the literature, including inattention to (a) differences in the conceptualization of OE/I in the questionnaire and lexical traditions and (b) the symptom heterogeneity of STPD. They then address these limitations in two large patient samples. The results suggest that OE/I per se is weakly associated with Psychoticism and STPD symptoms. However, unique variance specific to the different conceptualizations of OE/I demonstrates much stronger associations, often in opposing directions. These results clarify the debate and the seemingly discrepant views that OE/I is unrelated to Psychoticism and contains variance relevant to Psychoticism.

    Health sciences programs are being designed to attract students who are likely to stay and practice in rural and northern Canada. Consequently, student recruitment and screening are increasingly including assessment of suitability for rural practice. Although retention factors among rural physicians and nurses have been investigated, little is known about factors that contribute to the retention of other healthcare professionals who work in rural areas. The primary objective of this project was to identify the personal characteristics and experiences of allied health professionals who have worked long term in northern British Columbia (BC), Canada. The study used a qualitative descriptive approach. Six speech language pathologists, four psychologists, four occupational therapists, eight social workers, and four physiotherapists practicing long term in northern BC were recruited, using a convenience sample and the snowball technique, to participate in semi-structured telephone interviews. The interviews were audiotaped and transcribed verbatim. A thematic content analysis identified the motivations for their decision to begin or stay working in northern communities, the reasons for choosing rural or northern education and key themes concerning personal characteristics and experiences. A process of member checking and an external audit validated the analysis and findings. There were two major themes for choosing rural and northern education. For some, selection of rural or northern training was based on accessibility to health education programs; all participants who chose rural and northern education had already decided that they were going to practice rurally. Generally, participants identified past positive experiences and rural background as influencing their practice location decision. Participants named the community's need for healthcare professionals, career advancement opportunities, welcoming employers, peer support, as well as promises of continuing

    The Systematic Approach to Training (SAT) plays an important role in the safe operation of a nuclear power plant. It can often be seen as the answer to all training needs but it can sometimes fall victim to its own rigidity and inertia. This paper outlines the personal experiences and conceptual models of a former Human Resources Manager with responsibility for both pre operational and operational training. (author)

    To examine the experiences of caregiving among Vietnamese family members of persons living with HIV/AIDS. As the number of persons living with HIV/AIDS increases, the need of family caregivers who can take responsibility for the home care of these persons increases. Vietnam has one of the fastest growing HIV epidemics in Asia. A descriptive cross-sectional study with quantitative and qualitative methods was used. A purposive sample of 104 family caregivers, both male and female, participated voluntarily by answering a questionnaire of caregiver burden, and 20 of them participated in in-depth interview. Female caregivers were mainly mothers and wives while male caregivers were mainly husbands, fathers and siblings. The largest group of family caregivers reported moderate to severe burden. There was no difference between genders in total caregiver burden, but there were several differences between older and younger caregivers in some items of caregiver burden. Five categories of experiences emerged: Different types of caregiving to persons living with HIV/AIDS, cultural and religious issues associated with caregiving, keeping secret to avoid stigma and discrimination, lack of knowledge about disease and provision of care, and fear, anxiety and frustration. Stigma and discrimination should be decreased by providing knowledge to the general public about HIV/AIDS, in particular about ways of transmission and protection. Special knowledge should be given to family caregivers to enable them to give care to persons living with HIV/AIDS at home. This could be done through culturally appropriate training/intervention programmes in which coping methods should be included. Support group interventions should also be carried through. The results obtained can be used as baseline information. Health care providers should consider gender, age and culture of family members of persons living with HIV/AIDS. Knowledge about HIV/AIDS, provision of care at home and in hospital, and

    The rock album form, advantageously suited for the artistic expression of intrapsychic experience, has been virtually ignored by analytic writers. Remain in Light by Talking Heads is presented as an example of an album that effectively utilizes the potentialities of this form to give powerful and disconcerning musical expression to a variety of psychotic and schizoid experiences, bringing to life the formulations for these phenomena of Bion, Winnicott, Guntrip, Ogden, Grotstein and others. The album suggests a variety of mechanisms by which sound and music may serve both defensive and compensatory functions in relation to these phenomena.

    Do some life story patterns exist, which are associated with depression? Can some life story factors be identified, which influence or determine a special kind of personality, predisposing to depression? Retrospective, cross sectional study with nonexperimental character, using a number of 60 nonmelancholic depressed patients. First, they were asked to give an interview on their life story. Then, they were asked to fill in questionnaires about personality, parental style of raising, clinical symptoms and personality disorders. Significant correlations could be found between parental style of raising, a family history affected by depression, a dysfunctional household, the family composition, negative school experience and all investigated styles of personality. Further, clusters of personality, clusters of parental style of raising and clusters of specific life story factors could be detected. Results show a strong relation between life story factors and personality styles, predisposing to depression and emphasize the importance of considering personality, when exploring special life story factors. Vice versa, actual personality styles can point to different patterns of life story and thus, show the relevance for the diagnostic and therapeutic process.

    MRI and MRA are recommended today from the standpoint of sensitivity for the detraction of asymptomatic brain disease, and roentgenographic CT on head is not recommended. Under certain circumstances, however, having recently been given an opportunity of detecting brain disease by means of roentgenographic CT on head, we make a report of the diagnostic results. The examinees were the staff members of a non-profit organization consisting of 62 men and 56 women whose age was 48.6 years on the average. Asymptomatic brain disease was found in 6 cases including 1 case of cerebral infarction, 1 case of calcification of cerebral vascular wall and 1 case of cranial osteoma with a suspicion of Gardner syndrome. Incidentally, there were 31 cases with a complaint of headache, 20 cases of hypertension and 3 cases with a past history of head trauma. After such findings were obtained, guidance was provided to each of them. (author)

    RRC 'Kurchatov Institute' has performed coolant mixing investigation in a head of a full-size simulator of WWER-440 fuel assembly. The experiments were focused on obtaining the data important for investigating the trends in temperature difference between the value registered by a ICIS thermocouple and the value of average temperature. The completed experiments ensure representative of configuration simulation by reproducing every construction peculiar feature of flow part of fuel assembly in the domain between the lower spacing grid and thermocouple location, and also by slightly modified fuel assembly regular elements (or analogues thereof). For the purpose of effectiveness of coolant mixing assessment within the head cross section of FA simulator, we measured coolant temperature distribution both in the place where coolant flow leaves the rod bundle simulator (in 39 data points along the cross section) and in the cross section location of regular ICIS thermocouple simulator (30 data points). The testing was conducted with pressure of (90 - 95) bar, mass coolant flow rates up to 2000 kg/(m 2 .s), temperature of coolant heating in 'hot' parts of the bundle up to 35.. and differences between coolant temperature extremes measured in rod bundle simulator outlet up to 20... Temperature fields were registered in 63 conditions that differ in coolant flow and inlet coolant temperature, electrical heating rate of FA simulator, and radial coolant distribution. In certain registered conditions we simulated coolant leakage to the space between the fuel assemblies. The received test data may be important both for investigation of dependencies between the coolant temperature in regular thermocouple location or average outlet temperature in assembly head, and for validation of CFD codes or subchannel codes (Authors)

    A reliable literature finds that traits are related to each other in an organized hierarchy encompassing various conceptualizations of personality (e.g., Big Three, Five Factor Model). Recent work suggests the potential of a similar organization among our closest nonhuman relative, chimpanzees (Pan troglodytes), with significant links to neurobiology suggesting an evolutionarily- and neurobiologically-based hierarchical structure of personality. The current study investigated this hierarchical structure, the heritability of the various personality dimensions across levels of the hierarchy, and associations with early social rearing experience in a large sample (N = 238) of socially-housed, captive chimpanzees residing in two independent colonies of apes. Results provide support for a hierarchical structure of personality in chimpanzees with significant associations with early rearing experiences. Further, heritabilities of the various dimensions varied by early rearing, with affective dimensions found to be significantly heritable among mother-reared apes, while personality dimensions were largely independent of relatedness among the nursery-reared apes. Taken together, these findings provide evidence for the influence of both genetic and environmental factors on personality profiles across levels of the hierarchy, supporting the importance of considering environmental variation in models of quantitative trait evolution.

    Ewing's sarcoma accounts for 4-6% of primary malignant bone tumors and it affects the head and neck in only 1-4% of cases. The purpose of this study was to review the NCI experience with Ewing's sarcoma of the head and neck in children. Patients and Methods: A retrospective analysis of patient files with head and neck Ewing's sarcoma treated at the National Cancer Institute, Cairo University, Egypt, during the period from 1997 to 2008 was done. Files were reviewed and data for patients, tumor and treatment profile were extracted. Results: Twenty patients out of 280 with Ewing's sarcoma were identified during an 11 -year period. Patients had a median age of 11.5 years (range 5 months - 22 years) with a male to female ratio of 1:1. The most common tumor site was in the mandible (9/20, 45%) followed by a neck mass (4/20, 20%) and a clavicular mass (3/20, 15%). Six patients (30%) were metastatic at presentation. Most of the patients (19/20, 95%) received chemotherapy. Local therapy was in the form of radical radiotherapy for 8 patients (40%), 2 patients (10%) had surgery alone, while five patients (25%) had surgical resection and postoperative radiotherapy. Overall survival ranged from 1 to 128 months, with a median of 36 months. At the end of the study, 9 patients (45%) were alive in CR, 6 (30%) were lost to FU in disease progression, while 5 patients died from disease progression. Conclusion: Ewing's sarcoma of the head and neck is a disease of a rare incidence with debate about the optimum local therapy. Small non-metastatic tumors with good response to chemotherapy have abetter outcome.

    To examine how personality and leadership influence efficiency in the nursing service environment. Leadership and personality contribute to the success and failure of a unit. However, how they interact to influence performance is still understudied. We used matched pairs sample design to survey 135 head nurses and 1353 registered nurses on validated instruments of demographic characteristics, leadership styles and personality during June and July of 2014. Efficiency was calculated using Data Envelopment Analysis. Tobit regression was used for analysis. High conscientiousness and low neuroticism were significantly associated with higher efficiency. Particularly, under the initiating structure leadership style, high conscientiousness, high extraversion, high agreeableness, high openness and low neuroticism were related to higher efficiency. Openness would improve efficiency under a low consideration leadership style. Most personality traits were related to higher efficiency under the initiating leadership style. Only openness would improve leaders' efficiency under a high initiating structure and a low consideration leadership style. Considering personality as one factor of selecting head nurses, selecting the right person can improve the fit between individuals and organisations, which in turn, improves job performance. Training head nurses to develop better leadership styles in nurses is another way to enhance efficiency. © 2016 John Wiley & Sons Ltd.

    To evaluate the feasibility of PET/MRI (positron emission tomography/magnetic resonance imaging) with FDG ({sup 18}F-fluorodeoxyglucose) for initial staging of head and neck cancer. The study group comprised 20 patients (16 men, 4 women) aged between 52 and 81 years (median 64 years) with histologically proven squamous cell carcinoma of the head and neck region. The patients underwent a PET scan on a conventional scanner and a subsequent PET/MRI examination on a whole-body hybrid system. FDG was administered intravenously prior to the conventional PET scan (267-395 MBq FDG, 348 MBq on average). The maximum standardized uptake values (SUV{sub max}) of the tumour and of both cerebellar hemispheres were determined for both PET datasets. The numbers of lymph nodes with increased FDG uptake were compared between the two PET datasets. No MRI-induced artefacts where observed in the PET images. The tumour was detected by PET/MRI in 17 of the 20 patients, by PET in 16 and by MRI in 14. The PET/MRI examination yielded significantly higher SUV{sub max} than the conventional PET scanner for both the tumour (p < 0.0001) and the cerebellum (p = 0.0009). The number of lymph nodes with increased FDG uptake detected using the PET dataset from the PET/MRI system was significantly higher the number detected by the stand-alone PET system (64 vs. 39, p = 0.001). The current study demonstrated that PET/MRI of the whole head and neck region is feasible with a whole-body PET/MRI system without impairment of PET or MR image quality. (orig.)

    Abnormal time experience (ATE) in schizophrenia is a long-standing theme of phenomenological psychopathology. This is because temporality constitutes the bedrock of any experience and its integrity is fundamental for the sense of coherence and continuity of selfhood and personal identity. To characterize ATE in schizophrenia patients as compared to major depressives we interviewed, in a clinical setting over a period of 15 years, 550 consecutive patients affected by schizophrenic and affective disorders. Clinical files were analyzed by means of Consensual Qualitative Research (CQR), an inductive method suited to research that requires rich descriptions of inner experiences. Of the whole sample, 109 persons affected by schizophrenic (n = 95 acute, n = 14 chronic) and 37 by major depression reported at least 1 ATE. ATE are more represented in acute (N = 109 out of 198; 55%) than in chronic schizophrenic patients (N = 14 out of 103; 13%). The main feature of ATE in people with schizophrenia is the fragmentation of time experience (71 out of 109 patients), an impairment of the automatic and prereflexive synthesis of primal impression-retention-protention. This includes 4 subcategories: disruption of time flowing, déjà vu/vecu, premonitions about oneself and the external world. We contrasted ATE in schizophrenia and in major depression, finding relevant differences: in major depressives there is no disarticulation of time experience, rather timelessness because time lacks duration, not articulation. These core features of the schizophrenic pheno-phenotype may be related to self-disorders and to the manifold of characteristic schizophrenic symptoms, including so called bizarre delusions and verbal-acoustic hallucinations. © The Author 2015.

    2015-05-01

    The paper gives an overview about two research projects, both dealing with optical head tracking in hearing applications. As part of the project "Development of a real-time low-cost tracking system for medical and audiological problems (ELCoT)" a cost-effective single camera 3D tracking system has been developed which enables the detection of arm and head movements of human patients. Amongst others, the measuring system is designed for a new hearing test (based on the "Mainzer Kindertisch"), which analyzes the directional hearing capabilities of children in cooperation with the research project ERKI (Evaluation of acoustic sound source localization for children). As part of the research project framework "Hearing in everyday life (HALLO)" a stereo tracking system is being used for analyzing the head movement of human patients during complex acoustic events. Together with the consideration of biosignals like skin conductance the speech comprehension and listening effort of persons with reduced hearing ability, especially in situations with background noise, is evaluated. For both projects the system design, accuracy aspects and results of practical tests are discussed.

    Participants with personal and without personal experiences with the Earth as a sphere estimated large-scale distances between six cities located on different continents. Cognitive distances were submitted to a specific multidimensional scaling algorithm in the 3D Euclidean space with the constraint that all cities had to lie on the same sphere. A simulation was run that calculated respective 3D configurations of the city positions for a wide range of radii of the proposed sphere. People who had personally experienced the Earth as a sphere, at least once in their lifetime, showed a clear optimal solution of the multidimensional scaling (MDS) routine with a mean radius deviating only 8% from the actual radius of the Earth. In contrast, the calculated configurations for people without any personal experience with the Earth as a sphere were compatible with a cognitive concept of a flat Earth. 2010 Elsevier B.V.

    The use of personal protective clothing that covers the head is a common practice in many industries. Such personal protective clothing will impact the sound pressure level and the frequency content of sounds to which the wearer will be exposed. The use of such clothing, then, may impact speech and alarm audibility. A measure of the impact of such clothing is its insertion loss. Insertion loss measurements were performed on four types of personal protective clothing in use by Westinghouse Savannah River Company personnel which utilize cloth and plastic hood configurations to protect the head. All clothing configurations tested at least partially cover the ears. The measurements revealed that insertion loss of the items tested was notable at frequencies above 1000 Hz only and was a function of material stiffness and acoustic flanking paths to the ear. Further, an estimate of the clothing's noise reduction rating reveals poor performance in that regard, even though the insertion loss of the test articles was significant at frequencies at and above 1000 Hz.'

    2014-01-01

    To test for otolith asymmetries, several studies described horizontal translation of the body and head en bloc during fast vertical axis rotation. This stimulus causes one otolithic organ to rotate on-axis, and the other to experience centripetal acceleration. To test a new, more simple method of unilateral stimulation with head tilt and the body remaining on axis. During stationary and during 360 deg/s rotation, 12 healthy blindfolded subjects had their heads tilted 30 degrees sideways, positioning one otolithic organ on the axis of rotation after the other. The haptic subjective vertical (SV) was recorded several times by means of a manually adjustable rod. It was found that during stationary the SV tilted about 4 degrees on average in the direction of the head. During rotation, the SV tilted about 9 degrees on average. We therefore estimate the effect of eccentric otolith rotation to be 5 degrees on average. Tilt of the subjective vertical induced by head tilt during on-axis body rotation can provide a relatively uncomplicated alternative to test unilateral otolithic function as compared to body and head translation during rotation. Moreover, unlike eccentric rotation of the entire body, somatosensory cues are minimized by keeping the body fixed on axis and by subtracting the effect of head tilt per se.

    The head-mounted display (HMD) is a new image monitoring system. We developed the Personal Integrated-image Monitoring System (PIM System) using the HMD (HMZ-T2, Sony Corporation, Tokyo, Japan) in combination with video splitters and multiplexers as a surgical guide system for transurethral resection of the prostate (TURP). The imaging information obtained from the cystoscope, the transurethral ultrasonography (TRUS), the video camera attached to the HMD, and the patient's vital signs monitor were split and integrated by the PIM System and a composite image was displayed by the HMD using a four-split screen technique. Wearing the HMD, the lead surgeon and the assistant could simultaneously and continuously monitor the same information displayed by the HMD in an ergonomically efficient posture. Each participant could independently rearrange the images comprising the composite image depending on the engaging step. Two benign prostatic hyperplasia (BPH) patients underwent TURP performed by surgeons guided with this system. In both cases, the TURP procedure was successfully performed, and their postoperative clinical courses had no remarkable unfavorable events. During the procedure, none of the participants experienced any HMD-wear related adverse effects or reported any discomfort.

    Work-life balance has been examined at the collegiate level from multiple perspectives except for the athletic trainer (AT) serving in a managerial or leadership role. To investigate challenges and strategies used in achieving work-life balance from the perspective of the head AT at a National Collegiate Athletic Association Division I university. Qualitative study. Web-based management system. A total of 18 head ATs (13 men, 5 women; age = 44 ± 8 years, athletic training experience = 22 ± 7 years) volunteered. Participants journaled their thoughts and experiences in response to a series of questions. To establish data credibility, we included multiple-analyst triangulation, stakeholder checks, and peer review. We used a general inductive approach to analyze the data. Two higher-order themes emerged from our analysis of the data: organizational challenges and work-life balance strategies. The organizational challenges theme contained 2 lower-order themes: lack of autonomy and role demands. The work-life balance strategies theme contained 3 lower-order themes: prioritization of commitments, strategic boundary setting, and work-family integration. Head ATs are susceptible to experiencing work-life imbalance just as ATs in nonsupervisory roles are. Although not avoidable, the causes are manageable. Head ATs are encouraged to prioritize their personal time, make efforts to spend time away from their demanding positions, and reduce the number of additional responsibilities that can impede time available to spend away from work.

    To identify patterns of personal experience or behavior in self-neglect by exploring narratives of cognitively intact older adults. Descriptive study involving semistructured interviews and unstructured narratives. A parent study of self-neglect characteristics. Cognitively intact, self-neglecting older adults referred from 11 community-based senior services agencies (N = 69). Interviews included a comprehensive psychiatric assessment using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Axis-I and II Disorders and an unstructured interview that allowed subjects to describe important elements of their life stories. Content analysis was used to identify personal experiences and behavior patterns in each subject's narrative. Four types of traumatic personal experiences (psychologically traumatic loss, separation or abandonment (29%); violent victimization, physical trauma, or sexual abuse (19%); exposure to war or political violence (9%); prolonged mourning (7%)) and five behavior patterns (significant financial instability (23%), severe lifelong mental illness (16%), mistrust of people or paranoia (13%), distrust and avoidance of the medical establishment (13%), substance abuse or dependence (13%)) were identified in the life stories. Patterns of traumatic personal experiences and maladaptive behaviors that self-neglecters frequently report were identified. Experiences, perceptions, and behaviors developed over a lifetime may contribute to elder self-neglect. Further exploration and better understanding of these patterns may identify potential risk factors and areas for future targeted screening, intervention, and prevention. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

  18. An Examination of Personality Traits Associated with Autonomous Sensory Meridian Response (ASMR).

    2017-01-01

    Autonomous Sensory Meridian Response (ASMR) is a perceptual condition in which the presentation of particular audio-visual stimuli triggers intense, pleasurable tingling sensations in the head and neck regions, which may spread to the periphery of the body. These triggering stimuli are often socially intimate in nature, and usually involve repetition of movements and/or sounds (e.g., hearing whispering, watching someone brush her hair). Reports of ASMR experiences first appeared in online communities in 2010; since this time, these communities have expanded, with some groups consisting of over 100,000 members. However, despite the apparent prevalence of ASMR, there is currently no research on the personality characteristics that co-occur with this condition. In the current study, 290 individuals with ASMR and 290 matched controls completed the Big Five Personality Inventory (BFI; John et al., 1991); participants with ASMR also completed a questionnaire related to their ASMR phenomenology. Individuals with ASMR demonstrated significantly higher scores on Openness-to-Experience and Neuroticism, and significantly lower levels of Conscientiousness, Extraversion, and Agreeableness compared to matched controls. Further, ratings of subjective ASMR intensity in response to 14 common ASMR stimuli were positively correlated with the Openness-to-Experience and Neuroticism dimensions of the BFI. These results provide preliminary evidence that ASMR is associated with specific personality traits and suggest avenues for further investigation.

    Early carcinomas of the head and neck, category are highly amenable to treatment by conventional once-a-day radiation therapy with cure rates 60 to 90%. For the T2 lesions the rates range between 50 and 65%. For patients with advanced tumors, T3 and T4, the local and regional control extremely poor, with 3-year disease-free survivals approximately 25 to 30% (1,8); these lesions currently are managed in most centers by combined surgery and radiation therapy, with or without chemotherapy. Many strategies and procedures have been developed in the hope of controlling locally advanced tumors by radiation therapy alone, such as hyperbaric oxygen, hypoxic cell chemical sensitizers, high and low LET particle radiations, e.g., neutrons and protons, hyperthermia, and various radiation therapy fractionation schemes using two or three fractions per day (conventional dose per fraction with short overall time or multiple small doses with little change in overall time), low dose continuous radiation therapy, and split course treatment. The results of testing these approaches have not yet yielded conclusive evidence of clinical gain. The Radiation Medicine Service at the Massachusetts General Hospital began a program of twice-a-day radiation therapy for advanced carcinomas of the head and neck approximately 5 years ago. This chapter is a report of their experience with this treatment from October 1979 through April 1984

    An anthropological study has been carried out in order to evaluate the need expressed by patients undergoing radiotherapy treatment. The study was mostly qualitative and based on the radiotherapy experiences of 13 women with breast cancer and six men with head and neck cancer. A 24-year-old female anthropologist spent one year in the department of radiotherapy at the Bergonie Institute in Bordeaux. She collected data on patients' needs through the observation of their experience of treatment and personal interviews. These were put in context, analyzed both by qualitative and quantitative methods. The results pointed out the need for more information on the different steps of treatment and the patient's need 'for a smile'front the medical team; in other words, emphatic support. (author)

  4. Do you use your head or follow your heart? Self-location predicts personality, emotion, decision making, and performance.

    The head is thought to be rational and cold, whereas the heart is thought to be emotional and warm. In 8 studies (total N = 725), we pursued the idea that such body metaphors are widely consequential. Study 1 introduced a novel individual difference variable, one asking people to locate the self in the head or the heart. Irrespective of sex differences, head-locators characterized themselves as rational, logical, and interpersonally cold, whereas heart-locators characterized themselves as emotional, feminine, and interpersonally warm (Studies 1-3). Study 4 showed that head-locators were more accurate in answering general knowledge questions and had higher grade point averages, and Study 5 showed that heart-locators were more likely to favor emotional over rational considerations in moral decision making. Study 6 linked self-locations to reactivity phenomena in daily life--for example, heart-locators experienced greater negative emotion on high stressor days. In Study 7, we manipulated attention to the head versus the heart and found that head-pointing facilitated intellectual performance, whereas heart-pointing led to emotional decision making. Study 8 replicated Study 3's findings with a nearly year-long delay between the self-location and outcome measures. The findings converge on the importance of head-heart metaphors for understanding individual differences in cognition, emotion, and performance.

    Difficulty swallowing is a well-documented symptom in head and neck cancer and oesophageal malignancy. The frequency of oropharyngeal swallowing difficulties in the palliative phase of other malignancies is less reported. 1) To describe the patient experience of swallowing and associated difficulties while receiving specialist palliative care for malignancies other than those affecting the head and neck and 2) to identify the quality of life issues for the participants with dysphagia and compare with normative and dysphagic data provided by SWAL-QOL. Four month prospective pilot study - questionnaire design. Acute teaching hospital. Eleven patients receiving specialist palliative care. Participants were interviewed using a modified version of the SWAL-QOL, a validated quality of life assessment tool for use specifically with people with oropharyngeal dysphagia. Eight quality of life domains were explored as well as fourteen dysphagic symptoms. Seven of the 11 participants had dysphagic symptoms detailed in the SWAL-QOL and a further two patients reported transient dysphagic symptoms since diagnosis of their disease. Nine participants reported an impact on their quality of life and three reported a considerable impact in four or more domains. Eight of the 11 participants had self-selected softer textured foods. A notable group were three patients with lung cancer and one with lung metastases with a history of vocal fold motion impairment, all of who had experienced dysphagic symptoms since diagnosis. Patients with cancers not affecting the head and neck are at risk of developing symptoms of oropharyngeal dysphagia and subsequently, compromized nutrition, hydration and quality of life. Areas for further research are suggested.

    A new integrated magnetic head is described. The head was made by vacuum deposition using a mask. A magnetically coupled multilayer construction led to high performance. The results obtained indicate that the device functions equally well, for reading and writing. A set of calculations was developed which could simulate and optimize the behavior of the recording head. The results obtained with the writing were in good agreement with those obtained from experiments and quite different from results which have been several times previously published. In addition a new method was developed for measuring high fields in confined spaces; a 1000 A diameter probe was used in conjunction with a low angle diffraction procedure. The measurements give results which are very different from those obtained by current theories based on the magnetic potentials at the surface. (author) [fr

    Merkel cell carcinoma (MCC) is a rare cutaneous malignancy occurring mostly in older immunocompromised Caucasian males. A growing incidence of MCC has been reported in epidemiological studies. Treatment of MCC usually consists of surgical excision, pathological lymph node evaluation, and adjuvant radiotherapy. This paper reports the experience of a single tertiary center institution with 17 head and neck Merkel cell carcinoma patients. Median followup for the cohort was 37.5 months. After five years, recurrence-free survival, disease specific survival, and overall survival were 85%, 90%, and 83%, respectively. Our limited data support the use of adjuvant radiotherapy. We also report two cases of MCC located at the vestibule of the nose and two cases of spontaneous regression after diagnostic biopsy. About 40% of our patients were referred to our center for surgical revision and pathological lymph node evaluation. Increased awareness of MCC and an interdisciplinary approach are essential in the management of MCC.

    The aim of the present study was to determine the extent to which personality and treatment experience affect patients' appraisals of 4 complementary treatments for chronic pain. A total of 232 chronic pain patients (164 females, 68 males, average age 56.6 years) visiting a spa clinic in Austria returned a questionnaire on patient characteristics and personality (autonomy, depressiveness, assertiveness, self-control) as well as attitudes towards (i.e. appealing, effective, pleasant) and experience of the treatments. Results were analysed by use of linear regression analysis and confidence intervals. Although all treatments were appraised positively, the passive treatments (thermal water tub baths, classical massage) were favoured more than the active treatments (relaxation training or exercise therapy). Treatment appraisal was not predicted by any of the personality traits but to a large extent by treatment experience. Relaxing, not unpleasant treatments were the most highly esteemed treatments. How strenuous or tiring a treatment was only had a minor effect on its appraisal. Neither do dependent, passive patients prefer passive treatments, nor do conscientious patients prefer active treatments. Instead, the appraisal of treatments that induce specific somatosensory sensations is largely determined by treatment experiences, i.e. what the treatment feels like. Despite the popularity of CAM which encompasses many experientially intensive treatments, treatment experience has to date been a neglected topic of treatment research.

    Psilocybin has been used for centuries for religious purposes; however, little is known scientifically about its long-term effects. We previously reported the effects of a double-blind study evaluating the psychological effects of a high psilocybin dose. This report presents the 14-month follow-up and examines the relationship of the follow-up results to data obtained at screening and on drug session days. Participants were 36 hallucinogen-naïve adults reporting regular participation in religious/ spiritual activities. Oral psilocybin (30 mg/70 kg) was administered on one of two or three sessions, with methylphenidate (40 mg/70 kg) administered on the other session(s). During sessions, volunteers were encouraged to close their eyes and direct their attention inward. At the 14-month follow-up, 58% and 67%, respectively, of volunteers rated the psilocybin-occasioned experience as being among the five most personally meaningful and among the five most spiritually significant experiences of their lives; 64% indicated that the experience increased well-being or life satisfaction; 58% met criteria for having had a 'complete' mystical experience. Correlation and regression analyses indicated a central role of the mystical experience assessed on the session day in the high ratings of personal meaning and spiritual significance at follow-up. Of the measures of personality, affect, quality of life and spirituality assessed across the study, only a scale measuring mystical experience showed a difference from screening. When administered under supportive conditions, psilocybin occasioned experiences similar to spontaneously occurring mystical experiences that, at 14-month follow-up, were considered by volunteers to be among the most personally meaningful and spiritually significant of their lives.

    Existing services for the disabled do not cater for the needs of lame-brain survivors of severe head injury who may be capable of productive work though they may never become employable. A grant from the Nuffield Provincial Hospitals Trust made it possible to set up in 1967 a special workshop in premises provided by the regional hospital board. The hospital management committee assumed financial responsibility for the centre after three years, and after five years the Department of Health and Social Security purchased adjoining premises, which will double the present accommodation for about 35 persons. Though 45% of the 101 patients attending the workshop have returned to work, no financial support has yet been received from the Department of Employment. A suitably staffed hostel is needed for patients who live too far away to travel daily to and from the workshop. This undertaking has shown a need for special facilities for some of the victims of severe head injury, who differ in many important ways from other disabled persons.

    The overlooked aspect in Lithuania is the dearth of leaders among head nurses, who bear the responsibility for decisions in ethical dilemmas. Understanding the application of leadership styles is fundamental to ensuring head nurses' abilities to influence outcomes for healthcare providers and patients. To identify the leadership styles applied by head nurses in decision making in ethical dilemmas on hospital wards. The data were collected by questionnaires completed by head nurses (n = 278) working in five major state-funded hospitals in each of the five regions of Lithuania. The data were analysed using SPSS 16.0, calculating descriptive statistics and analysis of variance. Head nurses apply democratic, affiliative, transformational and sustainable leadership styles when resolving ethical dilemmas. The application of leadership styles is associated not only with specific situations, but also with certain background factors, such as years of experience in a head nurse's position, ward specialization and the incidence of ethical dilemmas. Nurses having been in a head nurse's position over 10 years use primitive leadership styles, notably bureaucratic leadership, more often than do those head nurses with only a few years of experience in such a position. The results highlight the need for head nurses to reflect on their practices and to find new ways of learning from practice, colleagues and patients. Head nurses' managerial decisions due to their 'executive power' can turn into a new state-of-the-art leadership in nursing. © 2013 The Authors.

    Personalized medicine offers the promise of better diagnoses, targeted therapies and individualized treatment plans. Pharmacogenomics is an integral component of personalized medicine; it aids in the prediction of an individual's response to medications. Despite growing public acceptance and emerging clinical evidence, this rapidly expanding field of medicine is slow to be adopted and utilized by healthcare providers, although many believe that they should be knowledgeable and able to apply pharmacogenomics in clinical practice. Institutional infrastructure must be built to support pharmacogenomic implementation. Multidisciplinary education for healthcare providers is a critical component for pharmacogenomics to achieve its full potential to optimize patient care. We describe our recent experience at the Mayo Clinic implementing pharmacogenomics education in a large, academic healthcare system facilitated by the Mayo Clinic Center for Individualized Medicine.

    Little is known about the impact of urbanicity, adverse neighborhood conditions and violent crime victimization on the emergence of adolescent psychotic experiences. Participants were from the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally-representative cohort of 2232 British twins who were interviewed about adolescent psychotic experiences at age 18. Urbanicity, neighborhood characteristics, and personal victimization by violent crime were measured during childhood and adolescence via geocoded census data, surveys of over 5000 immediate neighbors of the E-Risk participants, and interviews with participants themselves. Adolescents raised in urban vs rural neighborhoods were significantly more likely to have psychotic experiences (OR = 1.67, 95% CI = 1.21-2.30, P = .002). This association remained significant after considering potential confounders including family socioeconomic status, family psychiatric history, and adolescent substance problems (OR = 1.43, 95% CI = 1.01-2.03, P = .042), but became nonsignificant after considering adverse social conditions in urban neighborhoods such as low social cohesion and high neighborhood disorder (OR = 1.35, 95% CI = 0.94-1.92, P = .102). The combined association of adverse neighborhood social conditions and personal crime victimization with adolescent psychotic experiences (adjusted OR = 4.86, 95% CI = 3.28-7.20, P < .001) was substantially greater than for either exposure alone, highlighting a potential interaction between neighborhood conditions and crime victimization (interaction contrast ratio = 1.81, 95% CI = -0.03 to 3.65) that was significant at the P = .054 level. Cumulative effects of adverse neighborhood social conditions and personal victimization by violent crime during upbringing partly explain why adolescents in urban settings are more likely to report psychotic experiences.

    The use of head computed tomography (CT) is standard in the management of acute brain injury; however, there are inherent risks of transport of critically ill patients. Portable CT can be brought to the patient at any location. We describe the clinical use of a portable head CT scanner (CereTom: NeuroLogica: Danvers, MA) that can be brought to the patient's bedside or to other locations such as the operating room or angiography suite. Between June of 2006 and December of 2009, a total of 3421 portable CTs were performed. A total of 3278 (95.8%) were performed in the neuroscience intensive care unit (ICU) for an average of 2.6 neuroscience ICU CT scans per day. Other locations where CTs were performed included other ICUs (n = 97), the operating room (n = 53), the emergency department (n = 1), and the angiography suite (n = 2). Most studies were non-contrasted head CT, though other modalities including xenon/CT, contrasted CT, and CT angiography were performed. Portable head CT can reliably and consistently be performed at the patient's bedside. This should lead to decreased transportation-related morbidity and improved rapid decision making in the ICU, OR, and other locations. Further studies to confirm this clinical advantage are needed.

    This study examined the relationship between flow experience and place identity, based on eudaimonistic identity theory (EIT) which prioritizes self-defining activities as important for an individual’s identification of his/her goals, values, beliefs, and interests corresponding to one’s own identity development or enhancement. This study focuses on place identity, the identity’s features relating to a person’s relation with her/his place. The study is also based on flow theory, according to which some salient features of an activity experience are important for happiness and well-being. Questionnaire surveys on Italian and Greek residents focused on their perceived flow and place identity in relation to their own specific local place experiences. The overall findings revealed that flow experience occurring in one’s own preferred place is widely reported as resulting from a range of self-defining activities, irrespective of gender or age, and it is positively and significantly associated with one’s own place identity. Such findings provide the first quantitative evidence about the link between flow experienced during meaningfully located self-defining activities and identity experienced at the place level, similarly to the corresponding personal and social levels that had been previously already empirically tested. Results are also discussed in terms of their implications for EIT’s understanding and enrichment, especially by its generalization from the traditional, personal identity level up to that of place identity. More generally, this study has implications for maintaining or enhancing one’s own place identity, and therefore people–place relations, by means of facilitating a person’s flow experience within psychologically meaningful places.

    The authors provide a series of statements regarding the use of radiotherapy and surgery for metastatic squamous cancer to the neck. Some of these precepts are established facts requiring no additional documentation - for example, the combination of radiation and neck dissection for effective treatment of N2B neck disease or for subclinical disease, depending on extracapsular spread. Other precepts of the authors are not as generally accepted by head and neck surgeons, such as the mandatory staging of neck dissections following curative radiation therapy or the routine use of computerized tomography (CT) to confirm pathologic adenopathy. Most of the authors' precepts are supported by a combination of their personal clinical experience and hard data from the University of Florida, Gainesville

    Doctors will inevitably 1 day become patients. Whether as an acute emergency or as part of routine screening, doctors often find it difficult to recognise and act on their own healthcare needs. This article aims to provide a personal account and reflections from the point of view of a doctor in denial about his acute appendicitis, and a friend and fellow colleague's attempts to convince him to seek help. We review the challenges, learning points and literature about why doctors ignore their health needs, both physical and psychological, and suggest potential changes to tackle this issue based on the current literature, support networks and personal experiences. 2016 BMJ Publishing Group Ltd.

  5. Possible ramifications of introducing the institute of personal bankruptcy: The USA experience

    2016-01-01

    economic crisis and the role of personal bankruptcy as its most probable cause yields a conclusion that the adequate legal regulation of this process is paramount. The experiences of countries that have already introduced this legal institute are invaluable. The countries in the region which have set too rigorous rules for debt write-offs are currently facing the option of undertaking massive write-offs of debtors' claims, which are most unlikely to be objective. On the other hand, in the countries which have envisaged too flexible proceedings for debt write-offs, there is a negative selection of debtors and default of financial institutions. With this experience in mind, it is necessary to regulate and apply the institute of personal bankruptcy so that it provides for the maximum debt collection as well as for accomplishing the major social goals.

    Experience and implementation of dietary advice are influenced by various factors including ethnic, cultural and religious background. The aim is to explore how ethnic minority persons with diabetes experience dietary advice given by Norwegian health-workers, which strategies they have in response to the advice and how they explain their actions. In-depth interviews were performed with 15 Pakistani-born persons with type 2 diabetes living in Oslo. The analyses are based on the principles of Giorgi's interpretation of phenomenology. The participants expressed great concern to follow the advice. However, narratives about constraints were numerous. These concerned different life-situational factors, but more importantly they were related to communication problems arising from discontinuities between universalising medical knowledge and lay knowledge, as well as between different types of culturally defined lay knowledge. As a consequence, advice was generally experienced as inadequately based on the participant's food-cultural background, leaving the person with diabetes to do the translation between different levels of knowledge. In general health-workers would benefit from expanding their knowledge of the many positive aspects of their patients' cultural background, and apply their knowledge thereafter, whether it concerns (food)-culture or the impact of religion in everyday life.

    Authority control is critical for the quality of the bibliographic database. Authority control is important in guiding users from variant forms of headings to the controlled forms of headings and providing users with the related headings. With authority control, the forms of headings in the bibliographic records are consista,t and easy to access. Authority control not only increases the accuracy of searching but also makes retrieving records from the online bibliographic database easier. In the first part of the paper, the author brings out three formats for Chinese personal names in the online environment. Tire second part presents a new model for better authority control regarding Chinese presonal names. In the last part, the author emphasizes the importance of linking the online authority records with the bibliographic database. The quality of the database can be improved dramatically by providing vernacular access capability to the name authorty, records and ensuring that every personal name heading in the bibliographic records have corresponding Library of Congress name authority records。

    The tackle is responsible for the majority of head injuries during rugby union. In order to address head injury risk, risk factors during the tackle must first be identified. This study analysed tackle characteristics in the professional game in order to inform potential interventions. 464 tackles resulting in a head injury assessment (HIA) were analysed in detail, with tackle type, direction, speed, acceleration, nature of head contact and player body position the characteristics of interest. Propensity to cause an HIA was significantly greater for active shoulder tackles, front-on tackles, high speeder tackles and an accelerating tackler. Head contact between a tackler's head and ball carrier's head or shoulder was significantly more likely to cause an HIA than contact below the level of the shoulder (incident rate ratio (IRR) 4.25, 95%-CI 3.38 to 5.35). The tackler experiences the majority (78%) of HIAs when head-to-head contact occurs. An upright tackler was 1.5 times more likely to experience an HIA than a bent at the waist tackler (IRR 1.44, 95% CI 1.18 to 1.76). This study confirms that energy transfer in the tackle is a risk factor for head injury, since direction, type and speed all influence HIA propensity. The study provides evidence that body position and the height of tackles should be a focus for interventions, since lowering height and adopting a bent at the waist body position is associated with reduced risk for both tacklers and ball carriers. To this end, World Rugby has implemented law change based on the present data. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

    The topic of social care for older people has gained increasing attention from the part of academics, professionals, policy makers and media. However, we know little about this topic from the perspectives of older persons, which hinders future developments in terms of theory, empirical research, professional practice and social policy. This article presents and discusses a systematic review of relevant qualitative research-based evidence on the older persons' experiences and perspectives of receiving social care published between 1990 and September 2014. This review aimed to obtain answers to the following questions: How is the reception of social care experienced by the older persons? What are the negative and positive aspects of these experiences? What are the factors which influence the experiences? The synthesis of the findings of reviewed papers identified six analytical themes: asking for care as a major challenge; ambivalences; (dis)engagement in decisions concerning care; multiple losses as outcomes of receiving social care; multiple strategies to deal with losses originated by the ageing process; and properties of 'good care'. These themes are discussed from the point of view of their implications for theory, care practice and social policy, and future research. © 2015 John Wiley & Sons Ltd.

    What influences how people implicitly associate "past" and "future" with "front" and "back?" Whereas previous research has shown that cultural attitudes toward time play a role in modulating space-time mappings in people's mental models (de la Fuente, Santiago, Román, Dumitrache & Casasanto, 2014), we investigated real life experiences as potential additional influences on these implicit associations. Participants within the same single culture, who are engaged in different intermediate-term educational experiences (Study 1), long-term living experiences (Study 2), and short-term visiting experiences (Study 3), showed their distinct differences in temporal focus, thereby influencing their implicit spatializations of time. Results across samples suggest that personal attitudes toward time related to real life experiences may influence people's space-time mappings. The findings we report on shed further light on the high flexibility of human conceptualization system. While culture may exert an important influence on temporal focus, a person's conceptualization of time may be attributed to a culmination of factors. © 2017 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    Context: Work-life balance has been examined at the collegiate level from multiple perspectives except for the athletic trainer (AT) serving in a managerial or leadership role. Objective: To investigate challenges and strategies used in achieving work-life balance from the perspective of the head AT at a National Collegiate Athletic Association Division I university. Design: Qualitative study. Setting: Web-based management system. Patients or Other Participants: A total of 18 head ATs (13 men, 5 women; age = 44 ± 8 years, athletic training experience = 22 ± 7 years) volunteered. Data Collection and Analysis: Participants journaled their thoughts and experiences in response to a series of questions. To establish data credibility, we included multiple-analyst triangulation, stakeholder checks, and peer review. We used a general inductive approach to analyze the data. Results: Two higher-order themes emerged from our analysis of the data: organizational challenges and work-life balance strategies. The organizational challenges theme contained 2 lower-order themes: lack of autonomy and role demands. The work-life balance strategies theme contained 3 lower-order themes: prioritization of commitments, strategic boundary setting, and work-family integration. Conclusions: Head ATs are susceptible to experiencing work-life imbalance just as ATs in nonsupervisory roles are. Although not avoidable, the causes are manageable. Head ATs are encouraged to prioritize their personal time, make efforts to spend time away from their demanding positions, and reduce the number of additional responsibilities that can impede time available to spend away from work.

  14. What Can Metaphors Tell Us about Personality?

    Fetterman, Adam K; Robinson, Michael D

    2014-04-01

    Theorists propose that metaphors are not mere figures of speech, but can actively shape one's thoughts, feelings, and behaviors. Social psychologists have supported this claim over the past 10 years. Personality psychologists, though, have only recently begun investigating how metaphors can inform our understanding of what makes us different from each other. This review focuses on projects demonstrating links between metaphor and personality. As an example, people have been asked whether they locate the self in the head or the heart. Head people are (more) rational and cold, whereas heart people are emotional and warm. In addition, an individual differences approach can reveal what it is that metaphoric thinking does to and for people. Overall, individual difference approaches to common metaphors are shown to be informative not only in understanding how people differ from each other but also in extending the metaphor literature.

    There has been a long debate whether purposeful heading could cause harm to the brain. Studies have shown that repetitive heading could lead to degeneration of brain cells, which is similarly found in patients with mild traumatic brain injury. A two-degree of freedom linear mathematical model was developed to study the impact of soccer ball to the brain during ball-to-head impact in soccer. From the model, the acceleration of the brain upon impact can be obtained. The model is a mass-spring-damper system, in which the skull is modelled as a mass and the neck is modelled as a spring-damper system. The brain is a mass with suspension characteristics that are also defined by a spring and a damper. The model was validated by experiment, in which a ball was dropped from different heights onto an instrumented dummy skull. The validation shows that the results obtained from the model are in a good agreement with the brain acceleration measured from the experiment. This findings show that a simple linear mathematical model can be useful in giving a preliminary insight on what human brain endures during a ball-to-head impact.

  19. The moral experience of the patient with chronic pain: bridging the gap between first and third person ethics.

    Edwards, Ian; Jones, Mark; Thacker, Michael; Swisher, Laura Lee

    2014-03-01

    There has been a widespread call for an ethics in the management of patients with chronic pain which is patient centered and takes into account the lived experience of the patient. It has been argued in literature that current "duty" or principlist-based models of ethics (so-called 3rd person ethics) have not adequately addressed the needs of either patients or practitioners in this area. Two strands of literature within phenomenology were reviewed: the literature of interpretative phenomenological analysis and the study of the lived experience of the person with chronic pain; and the contribution of phenomenology in neo-Aristotelian virtue ethics (1st person ethics). Patients experience chronic pain in existential and moral terms in addition to their biomedical issues, facing dilemmas in understanding their own self-identity and in attempting to recover a sense of moral worth and agency. We outline a patient-centered ethics to underpin contemporary collaborative, multimodal approaches in the management of chronic pain. We firstly describe an agency-oriented, neo-Aristotelian 1st person ethics and then outline a hermeneutic relationship with extant "duty-based," 3rd person bioethics. The utility of the ethics model we propose (the ethical reasoning bridge) lies in its capacity for developing a sense of moral agency for both practitioner and patient, resonating with the current emphasis of seeking active engagement of patients in management.

  1. Opioid-Induced Nausea Involves a Vestibular Problem Preventable by Head-Rest.

    Directory of Open Access Journals (Sweden)

    Nadine Lehnen

    Full Text Available Opioids are indispensable for pain treatment but may cause serious nausea and vomiting. The mechanism leading to these complications is not clear. We investigated whether an opioid effect on the vestibular system resulting in corrupt head motion sensation is causative and, consequently, whether head-rest prevents nausea.Thirty-six healthy men (26.6 ± 4.3 years received an opioid remifentanil infusion (45 min, 0.15 μg/kg/min. Outcome measures were the vestibulo-ocular reflex (VOR gain determined by video-head-impulse-testing, and nausea. The first experiment (n = 10 assessed outcome measures at rest and after a series of five 1-Hz forward and backward head-trunk movements during one-time remifentanil administration. The second experiment (n = 10 determined outcome measures on two days in a controlled crossover design: (1 without movement and (2 with a series of five 1-Hz forward and backward head-trunk bends 30 min after remifentanil start. Nausea was psychophysically quantified (scale from 0 to 10. The third controlled crossover experiment (n = 16 assessed nausea (1 without movement and (2 with head movement; isolated head movements consisting of the three axes of rotation (pitch, roll, yaw were imposed 20 times at a frequency of 1 Hz in a random, unpredictable order of each of the three axes. All movements were applied manually, passively with amplitudes of about ± 45 degrees.The VOR gain decreased during remifentanil administration (p<0.001, averaging 0.92 ± 0.05 (mean ± standard deviation before, 0.60 ± 0.12 with, and 0.91 ± 0.05 after infusion. The average half-life of VOR recovery was 5.3 ± 2.4 min. 32/36 subjects had no nausea at rest (nausea scale 0.00/0.00 median/interquartile range. Head-trunk and isolated head movement triggered nausea in 64% (p<0.01 with no difference between head-trunk and isolated head movements (nausea scale 4.00/7.25 and 1.00/4.5, respectively.Remifentanil reversibly decreases VOR gain at a half

    In the diagnosis of head injury, Magnetic Resonance Imaging (MRI), like CT, is an effective method of distinguishing between intracerebral and extracerebral lesions. In our experience of MRI, early hematomas are almost isointense by Saturation Recovery (SR) method, so these must be performed with Spin Echo (SE) method for better visualization of hematomas. Isodense subdural hematomas, which is a diagnostic dilemma on CT images, are clearly seen on MRI. Delayed hematomas or residual parenchymal lesions are better demonstrated on MRI than on CT. Direct cornal, sagittal images and multiplanar facility of MRI provides excellent visualization of the the location and shape of extracerebral collection of hematoma. For the screening of head traumas, SE method is a technique of choice because of its excellent sensitivity within limited time.

    2011-01-01

    In recent years there has been an increased incidence of golf-associated head injuries in children and adolescents. At the authors' institution, they have identified a unique pattern of head injury associated with a swinging golf club. In this study, the authors highlight the mechanism of this injury and report their experience treating it. The authors reviewed the database of Rainbow Babies and Children's Hospital Trauma Center and performed a retrospective analysis of golf injuries recorded over a 10-year period (January 2000-April 2010). They identified 13 children (9 boys and 4 girls) who sustained head injuries in golfing accidents. All patients were 10 years of age or younger. The medical charts were reviewed and follow-up interviews were conducted to better delineate the details of the injuries. Injuries included 13 depressed skull fractures, 7 epidural hematomas, and 1 cerebral contusion. All 13 patients sustained their injuries after being struck in the head by a golf club. Seven sustained injuries on the follow-through of the initial swing and 3 sustained injuries on the backswing. All but one patient required neurosurgical intervention. Five patients developed neurological sequelae. None of the children had prior experience with golf equipment. All but one injury occurred in the child's own backyard. There was no direct supervision by an adult in any of the cases. Golfing can lead to serious head injuries in children. The authors noticed a unique pattern of golf-related head injuries, previously not described, that they have termed the "swing-ding." This golf club-inflicted injury occurs when a child stands too close to a swinging golfer and is struck in the head, subsequently sustaining a comminuted depressed skull fracture in the frontal or temporal region, with or without further intracranial injury. The study suggests that a lack of adult supervision, minimal previous golf experience, and proximity of the child to the swinging golfer are all

    2011-01-01

    This study explored the impact of prior personal experience with grief on self-reported personal and professional development of graduate students in nursing, social work, counseling, pastoral care, and genetic counseling involved as cofacilitators in bereavement support groups, and of medical students observing interdisciplinary inpatient palliative care. Personal experience with death of a family member or close friend was reported in 80% of the 35 participating students. Findings suggest that grief and the students' construction of the meaning of their loss can mediate the students' developing sense of self as a professional helper. Active engagement with suffering persons, the opportunity for self-disclosure and reflection, and teacher-facilitator provision of emotional guidance and modeling contributed positively to learning.

    While in general arousal increases with positive or negative valence (a so-called V-shaped relation), there are large differences among individuals in how these two fundamental dimensions of affect are related in people's experience. In two studies, we examined two possible sources of this variation: personality and culture. In Study 1, participants (Belgian university students) recalled a recent event that was characterized by high or low valence or arousal and reported on their feelings and their personality in terms of the Five-Factor Model. In Study 2, participants from Canada, China/Hong Kong, Japan, Korea, and Spain reported on their feelings in a thin slice of time and on their personality. In Study 1, we replicated the V-shape as characterizing the relation between valence and arousal, and identified personality correlates of experiencing particular valence-arousal combinations. In Study 2, we documented how the V-shaped relation varied as a function of Western versus Eastern cultural background and personality. The results showed that the steepness of the V-shaped relation between valence and arousal increases with Extraversion within cultures, and with a West-East distinction between cultures. Implications for the personality-emotion link and research on cultural differences in affect are discussed. © 2016 Wiley Periodicals, Inc.

  10. Transfer Pricing; Charging of head office costs

    Energy Technology Data Exchange (ETDEWEB)

    Andersen, Joergen

    1998-07-01

    The key issues discussed in this presentation are (1) What are head office costs?, (2) Why is the charging an area of concern for international companies?, (3) Which part of head office costs should be charged?, (4) OECD guidelines on charging. Head office costs are classified as Shareholder costs, Stewardship costs, Costs related to a specific subsidiary or group of subsidiaries (on call), and Costs related to operational activities in the parent company. The OECD reports of 1984 and 1996 are discussed. In Norsk Hydro's experience, the practising of the OECD guidelines by national authorities are confusing and not consistent over time or across borders. To get a better understanding of how charging of corporate head office costs are dealt with on an international level, Norsk Hydro asked Deloitte and Touche in London to carry out a study on international companies' behaviour. Their conclusions are included.

    As policy-makers contemplate expanding preschool opportunities for low-income children, one possibility is to fund two, rather than one year of Head Start for children at ages 3 and 4. Another option is to offer one year of Head Start followed by one year of pre-k. We ask which of these options is more effective. We use data from the Oklahoma pre-k study to examine these two ‘pathways’ into kindergarten using regression discontinuity to estimate the effects of each age-4 program, and propensity score weighting to address selection. We find that children attending Head Start at age 3 develop stronger pre-reading skills in a high quality pre-kindergarten at age 4 compared with attending Head Start at age 4. Pre-k and Head Start were not differentially linked to improvements in children’s pre-writing skills or pre-math skills. This suggests that some impacts of early learning programs may be related to the sequencing of learning experiences to more academic programming. PMID:27076692

    Full Text Available OBJECTIVES: Patients with Type I neurofibromatosis scoliosis with intra-canal rib head protrusion are extremely rare. Current knowledge regarding the diagnosis and treatment for this situation are insufficient. The purpose of this study is to share our experience in the diagnosis and surgical treatments for such unique deformities. METHODS: Six patients with Type I neurofibromatosis scoliosis with rib head dislocation into the spinal canal were diagnosed at our institution. Posterior instrumentation and spinal fusion without intra-canal rib head resection via a posterior-only approach was performed for deformity correction and rib head extraction. The efficacy and outcomes of the surgery were evaluated by measurements before, immediately and 24 months after the surgery using the following parameters: coronal spinal Cobb angle, apex rotation and kyphosis of the spine and the intra-canal rib head position. Post-operative complications, surgery time and blood loss were also evaluated. RESULTS: Patients were followed up for at least 24 months post-operatively. The three dimensional spinal deformity was significantly improved and the intra-canal rib head was significantly extracted from the canal immediately after the surgery. At follow-up 24 months after surgery, solid fusions were achieved along the fusion segments, and the deformity corrections and rib head positions were well maintained. There were no surgery-related complications any time after the surgery. CONCLUSIONS: Systematic examinations are needed to identify patients with Type I neurofibromatosis scoliosis with rib head dislocation into the canal who can be treated by posterior-only spinal fusion without rib head resection.

    Full Text Available Rita Sommerseth, Elin DysvikUniversity of Stavanger, Faculty of Social Sciences, Department of Health Studies, Stavanger, NorwayObjective: The basic aim in this paper is to discuss health care professionals’ experiences of person-centered collaboration and involvement in mental health rehabilitation and suggest ways of improving this perspective. Furthermore, the paper explains the supportive systems that are at work throughout the process of rehabilitation.Method: The study design is a qualitative approach using three focus group interviews with a total of 17 informants with different professional backgrounds such as nurses, social workers, and social pedagogies. In addition, one nurse and one social worker participated in a semistructured in-depth interview to judge validity.Results: Our results may demonstrate deficits concerning mental health care on several levels. This understanding suggests firstly, that a person-centered perspective and involvement still are uncommon. Secondly, multidisciplinary work seems uncommon and only sporadically follows recommendations. Thirdly, family support is seldom involved. Lastly, firm leadership and knowledge about laws and regulations seems not to be systematically integrated in daily care.Conclusion: Taking these matters together, the improvement of a person-centered perspective implies cooperation between different services and levels in mental health care. In order to bring about improvement the health care workers must critically consider their own culture, coordination of competence must be increased, and leadership at an institutional and organizational level must be improved so that scarce rehabilitation resources are used to the optimal benefit of people with a mental illness.Keywords: multidisciplinary teams, person-centered collaboration, supportive systems, rehabilitation

    The purpose of this study was to explore the role of personality traits and driving experience in the prediction of risky driving behaviors and accident risk among Chinese population. A convenience sample of drivers (n=511; mean (SD) age=34.2 (8.8) years) completed a self-report questionnaire that was designed based on validated scales for measuring personality traits, risky driving behaviors and self-reported accident risk. Results from structural equation modeling analysis demonstrated that the data fit well with our theoretical model. While showing no direct effects on accident risk, personality traits had direct effects on risky driving behaviors, and yielded indirect effects on accident risk mediated by risky driving behaviors. Both driving experience and risky driving behaviors directly predicted accident risk and accounted for 15% of its variance. There was little gender difference in personality traits, risky driving behaviors and accident risk. The findings emphasized the importance of personality traits and driving experience in the understanding of risky driving behaviors and accident risk among Chinese drivers and provided new insight into the design of evidence-based driving education and accident prevention interventions.

    Full Text Available Background: Rehabilitation is of fundamental importance for the persons with disability to achieve functional independence and have an improved quality of life. To enhance the effectiveness of rehabilitation, it  is  important  to  seek  clients’  perspectives  of  the  rehabilitation  services and  to  incorporate  these  perspectives  into  the  planning  and  delivery  of rehabilitation  services.  The  aim  of  this  study  was  to  explore  the  persons with  physical  disabilities’  experiences  of  the  rehabilitation  services  they received at Community Health Centres (CHCs. Methods: In-depth  qualitative  interviews  were  used  to  collect  data.  Ten  persons  with  physical  disabilities,  who  had  received  rehabilitation  services at CHCs participated in the in-depth interviews. The interviews were tape-recorded and transcribed verbatim.  Thematic analysis was used to analyse the data.  Results: The  clients  experienced  problems  with  accessing  transport  and  obtaining  information  from  the  service providers. Experiences regarding clients’ involvement in the rehabilitation were varied. All the clients reported positive experiences regarding their interaction with service providers and family involvement. Conclusion: The experiences of the participants who accessed CHCs for rehabilitation were positive and negative. The service providers should therefore address the aspects of rehabilitation that were negatively experienced.

    Full Text Available A multitude of challenges comes into play when attempting to design (and evaluate an interactive digital storytelling experience for use by visitors in a museum. This paper reports on the evaluation of the prototype mobile-based storytelling “guides” designed, developed and deployed as part of a research project at the Acropolis Museum in Athens, Greece. Experiences designed for different visitor profiles were evaluated several times throughout the iterative design process, in a number of on-site studies, and with more than 180 museum visitors of all ages (with this paper reporting on two studies conducted with a total of 53 users visiting individually or in pairs. The evaluation methods included ethnography (i.e., observation of visitors in the Museum’s galleries, pre- and post-experience in-depth interviews and questionnaires to measure the Users’ Experience (UX, as well as data logging. The analysis of the data focused on themes representing components of the experiences, such as interactive story plot and narration, staging and way-finding in the physical space, personalization and social interaction. Our findings confirmed that understanding UX and what makes it effective or not in the rich context of a cultural setting is a complex endeavor. The paper discusses our findings and proposes relevant recommendations for the design of digital experiences for cultural, educational, and recreational purposes.

  18. Personal disclosure revisited.

    Science.gov (United States)

    Olarte, Silvia W

    2003-01-01

    In this paper personal disclosure is defined as a conscious verbal presentation to the patient by the therapist of a personal vignette accompanied by the appropriate dynamic formulation and resolution of a given personal area of conflict. It is conceptualized within theoretical formulations which consider the therapeutic relationship a dyad, where the reality of the patient and the reality of the therapist influence each other, providing the matrix through which the resolution of the patient's past life experiences takes place in the context of this new interpersonal experience. It is specifically differentiated from a boundary violation, because the personal disclosure is brought to the patient's interactional awareness not for gratification of the therapist's sexual or narcissistic needs, but to provoke a response in the patient's conceptualization of a phenomenon being presented in the session and to actively influence the intersubjective field. Within the conceptual framework developed in this paper, personal disclosure reaffirms the patient's current self-discovery and provides for a different formative experience. Personal disclosure is not to be used by the therapist as a vehicle to resolve personal conflicts or as source of personal gratification. When used within the context developed in this paper, personal disclosure enhances both the patient's therapeutic process and the therapist's ever-evolving growth.

    Data from the Head Start Impact Study ( N = 1,141) and the Head Start Family and Child Experiences Survey, 2009 Cohort ( N = 825) were used to investigate whether Spanish instruction in Head Start differentially increased Spanish-speaking Dual Language Learners' (DLLs) academic achievement. Although hypothesized that Spanish instruction would be beneficial for DLLs' early literacy and math skills, results from residualized growth models showed there were no such positive associations. Somewhat surprisingly, DLL children instructed in Spanish had higher English receptive vocabulary skills at the end of the Head Start year than those not instructed, with children randomly assigned to Head Start and instructed in Spanish having the highest scores. Policy implications for Head Start-eligible Spanish-speaking DLLs are discussed.

    Configuration II of the ULPU experimental facility is described, and from a comprehensive set of experiments are provided. The facility affords full-scale simulations of the boiling crisis phenomenon on the hemispherical lower head of a reactor pressure vessel submerged in water, and heated internally. Whereas Configuration I experiments (published previously) established the lower limits of coolability under low submergence, pool-boiling conditions, with Configuration II we investigate coolability under conditions more appropriate to practical interest in severe accident management; that is, heat flux shapes (as functions of angular position) representative of a core melt contained by the lower head, full submergence of the reactor pressure vessel, and natural circulation. Critical heat fluxes as a function of the angular position on the lower head are reported and related the observed two-phase flow regimes.

    To investigate the role of parenting in the development of adult antisocial personality traits. A total of 742 community-based subjects were assessed for adult DSM-IV antisocial personality disorder traits and for measures of parental behavior experienced as children, including by the Parental Bonding Instrument (PBI). Three fundamental dimensions of parental behavior - care, behavioral restrictiveness and denial of psychological autonomy - were derived by factor analysis from the PBI. These dimensions significantly correlated with measures of parental behavior considered influential in later antisocial behavior. Adult antisocial traits in males were associated with low maternal care and high maternal behavioral restrictiveness, and in females, antisocial traits were associated with low paternal care and high maternal denial of psychological autonomy. These dimensions did not, however, explain all variance parental behavior has on adult antisocial personality traits. Adult antisocial personality traits are associated with experiences of low parental care and maternal overprotection.

    Colleges and universities across the country and around the world have embraced the Earth system approach to gain deeper understanding of the interrelationships of processes that define the home planet. The Design Guide for Undergraduate Earth System Science Education, a product of the NASA/USRA Earth System Science Education for the 21st Century Program (ESSE 21), represents a synthesis of community understanding of the content and process of teaching and learning about Earth as a system. The web-based Design Guide serves faculty from multiple disciplines who wish to adopt an ESS approach in their own courses or programs. Illustrating the nine topical sections of the Design Guide are a series of short vignettes telling the story of how ESS is being used in the classroom, how ESS has contributed to institutional change and personal professional development, how ESS is being implemented at minority serving institutions, and the impact of ESS education on student research. Most vignettes are written from a personal perspective and reflect a direct experience with Earth System Science Education. Over forty vignettes have been assembled aiming to put a face on the results of the systemic reform efforts of the past fifteen years of the ESSE programs, documenting the sometimes intangible process of education reform to be shared with those seeking examples of ESS education. The vignettes are a vital complement to the Design Guide sections, and are also available as a separate collection on the Design Guide and ESSE 21 web sites.

    Background Globally, head injury is a substantial cause of mortality and morbidity. A disproportionately greater burden is borne by low- and middle-income countries. The incidence and characteristics of fatal and hospitalised head injuries in Fiji are unknown. Methods Using prospective data from the Fiji Injury Surveillance in Hospital system, the epidemiology of fatal and hospitalised head injuries was investigated (2004–2005). Results In total, 226 hospital admissions and 50 fatalities (66% died prior to admission) with a principal diagnosis of head injury were identified (crude annual rates of 34.7 and 7.7/100,000, respectively). Males were more likely to die and be hospitalised as a result of head injury than females. The highest fatality rate was among those in the 30–44-year age group. Road traffic crashes were the leading causes of injuries resulting in death (70%), followed by ‘hit by person or object’ and falls (14% each). Among people admitted to hospital, road traffic crashes (34.5%) and falls (33.2%) were the leading causes of injury. The leading cause of head injuries in children was falls, in 15–29-year-olds road traffic crashes, and in adults aged 30–44 years or 45 years and older ‘hit by person or object’. Among the two major ethnic groups, Fijians had higher rates of falls and ‘hit by person or object’ and Indians higher rates for road traffic crashes. There were no statistically significant differences between the overall rates of head injuries or the fatal and non-fatal rates among Fijians or Indians by gender following age standardisation to the total Fijian national population. Conclusion Despite underestimating the overall burden, this study identified head injury to be a major cause of death and hospitalisation in Fiji. The predominance of males and road traffic-related injuries is consistent with studies on head injuries conducted in other low- and middle-income countries. The high fatality rate among those aged 30–44

    Full Text Available Background: Near death experiences (NDE are receiving increasing attention by the scientific community because not only do they provide a glimpse of the complexity of the mind-brain interactions in ′near-death′ circumstances but also because they have significant and long lasting effects on various psychological aspects of the survivors. The over-all incidence-reports of NDEs in literature have varied widely from a modest Figure of 10% to around 35%, even up to an incredible Figure of 72% in persons who have faced close brush with death. Somewhat similar to this range of difference in incidences are the differences prevalent in the opinions that theorists and researchers harbor around the world for explaining this phenomena. None the less, objective evidences have supported physiological theories the most. A wide range of physiological processes have been targeted for explaining NDEs. These include cerebral anoxia, chemical alterations like hypercapnia, presence of endorphins, ketamine, and serotonin, or abnormal activity of the temporal lobe or the limbic system. In spite of the fact that the physiological theories of NDEs have revolved around the derangements in brain, no study till date has taken up the task of evaluating the experiences of near-death in patients where specific injury has been to brain.

    2013-01-01

    Reflecting on negative personal experiences has implications for mood that may vary as a function of specific domains (e.g., achievement vs. interpersonal) and cultural orientation (e.g., interdependence vs. independence). This study investigated cultural differences in the social-cognitive and affective processes undertaken as Easterners and Westerners reflected on negative interpersonal and performance experiences. One hundred Asian Americans and 92 European-American college students were randomly assigned to one of three conditions: interpersonal rejection, achievement failure, or a control condition. Results revealed that Asian Americans experienced greater distress than European Americans after self-reflecting over a failed interpersonal experience, suggesting cultural sensitivity in the relational domain. Consistent with theoretical predictions, analysis of the social cognitive and affective processes that participants engaged in during self-reflection provided some evidence that self-enhancement may buffer distress for European Americans, while emotion suppression may be adaptive for Asian Americans.

  10. Head pose estimation from a 2D face image using 3D face morphing with depth parameters.

    Kong, Seong G; Mbouna, Ralph Oyini

    2015-06-01

    This paper presents estimation of head pose angles from a single 2D face image using a 3D face model morphed from a reference face model. A reference model refers to a 3D face of a person of the same ethnicity and gender as the query subject. The proposed scheme minimizes the disparity between the two sets of prominent facial features on the query face image and the corresponding points on the 3D face model to estimate the head pose angles. The 3D face model used is morphed from a reference model to be more specific to the query face in terms of the depth error at the feature points. The morphing process produces a 3D face model more specific to the query image when multiple 2D face images of the query subject are available for training. The proposed morphing process is computationally efficient since the depth of a 3D face model is adjusted by a scalar depth parameter at feature points. Optimal depth parameters are found by minimizing the disparity between the 2D features of the query face image and the corresponding features on the morphed 3D model projected onto 2D space. The proposed head pose estimation technique was evaluated on two benchmarking databases: 1) the USF Human-ID database for depth estimation and 2) the Pointing'04 database for head pose estimation. Experiment results demonstrate that head pose estimation errors in nodding and shaking angles are as low as 7.93° and 4.65° on average for a single 2D input face image.

    This research examined the personality of owners of personal Web sites based on self-reports, visitors' ratings, and the content of the Web sites. The authors compared a large sample of Web site owners with population-wide samples on the Big Five dimensions of personality. Controlling for demographic differences, the average Web site owner reported being slightly less extraverted and more open to experience. Compared with various other samples, Web site owners did not generally differ on narcissism, self-monitoring, or self-esteem, but gender differences on these traits were often smaller in Web site owners. Self-other agreement was highest with Openness to Experience, but valid judgments of all Big Five dimensions were derived from Web sites providing rich information. Visitors made use of quantifiable features of the Web site to infer personality, and the cues they utilized partly corresponded to self-reported traits. Copyright 2006 APA, all rights reserved.

    2008-02-01

    To illuminate meanings of being in a psycho-geriatric unit. Background. There are known risks associated with moving persons with dementia from home to an institution, but little is known about how they experience being in psycho-geriatric units. Using open-ended research interviews, six persons with mild to severe dementia were asked to narrate about their experiences in the hospital. The interviews were interpreted using a phenomenological hermeneutical method of analysis. The comprehensive understanding of being in a psycho-geriatric unit points towards an understanding of being lost in the present but confident of the past. The analysis showed that the participants appeared lost as they could not narrate where they were and why, but that they became confident when narrating about their previous life. The analysis also showed that being in the hospital meant sharing living space with strangers, invasions of private space and establishing new acquaintances. Being in the unit could also mean boredom and devaluation for participants. The interviews were interpreted in the light of narrative theory of identity: persons with dementia narrating about previous life experiences as to make claims of how to be interpreted by others; as persons instead of merely as 'demented' patients. Experiences of care narrated by persons with dementia present meaningful and useful information that can provide feedback to inform care practice. Experiences of care from persons with dementia provide meaningful information about care and the doing and being of staff. Creating time for conversations with these persons may facilitate well-being.

    A method of investigating head acceleration and intracranial dynamics from stick impacts in girls' and women's lacrosse was developed using headform impact experiments and a finite element head model. Assessing the likelihood of head injury due to stick-head impacts is of interest in girls' and women's lacrosse due to the current lack of head protection during play. Experimental and simulation data were compared to characterize the head acceleration caused by stick-head impacts. Validation against cadaver head impact experiments ensures that the finite element model, with its relatively simple material properties, can provide means to develop a better understanding of the intracranial dynamics during lacrosse stick impacts. Our numerical results showed the peak acceleration at the center of gravity increased linearly with impact force, and was generally in agreement with the experimental data. von Mises stresses and peak principal strains, two common literature injury indicators, were examined within the finite element model, and peak values were below the previously reported thresholds for mild traumatic brain injury. By reconstructing typical in-game, unprotected stick-head impacts, this investigation lays the foundation for a quantitative methodology of injury prediction in girls' and womens' lacrosse.

  17. Did René Descartes Have Exploding Head Syndrome?

    René Descartes (1596-1650), "the Father of Modern Philosophy" and advocate of mind-body dualism, had three successive dreams on November 10, 1619 that changed the trajectory of his life and the trajectory of human thought. Descartes' influential dreams have been of interest to a number of commentators including the famous neurologist and psychoanalyst Sigmund Freud. Descartes' second dream in particular, in which he heard a loud noise in his head before seeing a bright flash of light upon awakening, has been discussed extensively. Commentators have employed psychoanalytic and medical explanations to account for Descartes' unusual nocturnal experience. In this tradition, I propose that Descartes' second dream was not a dream at all; rather, it was an episode of exploding head syndrome; a benign and relatively common parasomnia. I further suggest that Adrien Baillet's account of Descartes' experience constitutes the earliest description of exploding head syndrome, predating the account described by Silas Weir Mitchell in 1876 by nearly 200 years. © 2018 American Academy of Sleep Medicine.

  18. Heads First: Visual Aftereffects Reveal Hierarchical Integration of Cues to Social Attention.

    Directory of Open Access Journals (Sweden)

    Sarah Cooney

    Full Text Available Determining where another person is attending is an important skill for social interaction that relies on various visual cues, including the turning direction of the head and body. This study reports a novel high-level visual aftereffect that addresses the important question of how these sources of information are combined in gauging social attention. We show that adapting to images of heads turned 25° to the right or left produces a perceptual bias in judging the turning direction of subsequently presented bodies. In contrast, little to no change in the judgment of head orientation occurs after adapting to extremely oriented bodies. The unidirectional nature of the aftereffect suggests that cues from the human body signaling social attention are combined in a hierarchical fashion and is consistent with evidence from single-cell recording studies in nonhuman primates showing that information about head orientation can override information about body posture when both are visible.

  1. Experimental study of head loss and filtration for LOCA debris

    Rao, D.V.; Souto, F.J.

    1996-02-01

    A series of controlled experiments were conducted to obtain head loss and filtration characteristics of debris beds formed of NUKON trademark fibrous fragments, and obtain data to validate the semi-theoretical head loss model developed in NUREG/CR-6224. A thermally insulated closed-loop test set-up was used to conduct experiments using beds formed of fibers only and fibers intermixed with particulate debris. A total of three particulate mixes were used to simulate the particulate debris. The head loss data were obtained for theoretical fiber bed thicknesses of 0.125 inches to 4.0 inches; approach velocities of 0.15 to 1.5 ft/s; temperatures of 75 F and 125 F; and sludge-to-fiber nominal concentration ratios of 0 to 60. Concentration measurements obtained during the first flushing cycle were used to estimate the filtration efficiencies of the debris beds. For test conditions where the beds are fairly uniform, the head loss data were predictable within an acceptable accuracy range by the semi-theoretical model. The model was equally applicable for both pure fiber beds and the mixed beds. Typically the model over-predicted the head losses for very thin beds and for thin beds at high sludge-to-fiber mass ratios. This is attributable to the non-uniformity of such debris beds. In this range the correlation can be interpreted to provide upper bound estimates of head loss. This is pertinent for loss of coolant accidents in boiling water reactors

    1992-01-01

    Following the world tendency in the application of microcomputers in measuring instrumentation, standard personal computer, compatible with IBM PC/XT, was employed in the isotope gauges developed lately in the Institute. The are: beta backscatter coating thickness gauge, X-ray fluorescence multilayer coating thickness gauge with X-ray tube as radiation source, and automatic airborne dust pollution gauge. A simple interface containing: address decoder, programmable pulse counter, some buffers and latches was sufficient to connect the computer to the measuring head of the gauges. Thanks to the possibility of programming in higher level language (turbo Pascal), the gauges were developed in much shorter time than required for classical electronics. The experience gained during development of the gauges shows, that even in case of a simple instrument such as the beta backscatter coating thickness gauge, it is more economical to employ ready-made personal computer than to elaborate specific electronics for it, unless the gauge is produced in large numbers. The use of personal computer is particularly advantageous, when processing of the signal or control of the measuring cycle is more sophisticated, as in the case of the two other gauges. Block diagrams of the gauges and their interfaces are presented in the paper. In case of the airborne dust pollution gauge, flow chart of the computer program is also given. (author). 3 refs, 4 figs

    To assess the spectrum and management of head injuries among earthquake victims. Three hundred consecutive cases of head injury, secondary to earthquake were included in the study. Plain X-rays of skulls were undertaken in clinically stable patients with head injuries. Cases with altered level of consciousness and compound depressed fractures were advised CT scan of head. Pus swabs were taken from open wounds. Proformas were maintained for every patient. Head injury was classified as mild, moderate and severe, and each patient was treated accordingly. One hundred and twenty three (41%) patients were children under 10 years of age. Adults below 55 years were 69 (23%) and above 55 years were 108 (36%). Mean age was 32.2 years (SD + 6.7). Female to male ratio was 1.1:1. One hundred and sixty five (55%) cases were of mild head injury, 103 (34.3%) patients had moderate head injury and 32 (10.7%) patients had severe head injury. Majority (48.7%) of patients was managed conservatively. Minor surgeries were done in 17% of patients and major surgeries were done in 34.3% of patients. Glasgow Outcome Scale assessment was made at the end of 6 months and 1 year. Mortality increased from 3.3% to 7% in one year time. Patients at the extremes of age are more vulnerable to trauma and should be given timely attention in disaster management plans. General and trauma surgeons should be well-versed with the techniques and indications of burr hole evacuation of life threatening intracranial haematomas in situations, where early evacuation is unattainable.

    Head and neck cancer is a common and aggressive malignancy with a high morbidity and mortality profile. Although the large majority of cases resemble head and neck squamous cell carcinoma (HNSCC), the current classification based on anatomic site and tumor stage fails to capture the high level of biologic heterogeneity, and appropriate clinical management remains a major challenge. Hence, a better understanding of the molecular biology of HNSCC is urgently needed to support biomarker development and personalized care for patients. This review focuses on recent findings based on integrative genomics analysis and multi-scale modeling approaches and how they are beginning to provide more sophisticated clues as to the biological and clinical diversity of HNSCC. © 2017 S.

    Analyzes motion of the cutter head of the AM-50 heading machine. Two types of head motion are comparatively evaluated: planar motion and spatial motion. The spatial motion consists of the head rotational motion and horizontal or vertical feed motion, while planar motion consists of rotational motion and vertical feed motion. Equations that describe head motion under conditions of cutter vertical or horizontal feed motion are derived. The angle between the cutting speed direction and working speed direction is defined. On the basis of these formulae variations of cutting speed depending on the cutting tool position on a cutter head are calculated. Calculations made for 2 extreme cutting tools show that the cutting speed ranges from 1,205 m/s to 3,512 m/s. 4 refs.

  7. Henry Head and the Theatre of Reverie

    Directory of Open Access Journals (Sweden)

    Tiffany Watt-Smith

    2011-04-01

    Full Text Available In 1903, the neurologist Henry Head (1861-1940 embarked on a painful self-experiment, in which he severed the radial nerve of his left arm, and then charted the gradual and faltering return of sensitivity to the limb over the next four and a half years. To directly experience his own sensations, Head entered into a trance-like state of distraction or reverie he called a ‘negative attitude of attention’. This article explores Head’s peculiar technique for looking within, and argues that while introspection was an established strategy in psychological laboratories, Head’s reverie also resonated with techniques associated with actors and theatrical audiences during this period. Viewing psychological self-experimentation through the lens of theatre, this article makes visible aspects of Head’s embodied, affective laboratory encounters, often obscured in accounts of his experiment. At the same time, it proposes that the broader historical and cultural significance of Head’s experiment lies in his attempt to observe himself by producing states of inattention and reverie at will, mental ‘attitudes’ that were themselves the subject of a rapidly evolving debate in scientific and aesthetic circles at the turn of the twentieth century.

    Managing chronic illness requires personal health information management (PHIM) to be performed by lay individuals. Paramount to understanding the PHIM process is understanding the sociotechnical system in which it frequently occurs: the home environment. We combined distributed cognition theory and the patient work system model to investigate how characteristics of the home interact with the cognitive work of PHIM. We used a 3D virtual reality CAVE that enabled participants who had been diagnosed with diabetes (N = 20) to describe how they would perform PHIM in the home context. We found that PHIM is distinctly cognitive work, and rarely performed 'in the head'. Rather, features of the physical environment, tasks, people, and tools and technologies present, continuously shape and are shaped by the PHIM process. We suggest that approaches in which the individual (sans context) is considered the relevant unit of analysis overlook the pivotal role of the environment in shaping PHIM. Practitioner Summary: We examined how Personal Health Information Management (PHIM) is performed in the homes of diabetic patients. We found that approaches to studying cognition that focus on the individual, to the exclusion of their context, overlook the pivotal role of environmental, social, and technological features in shaping PHIM.

    Adverse childhood experiences, comprised of forms of maltreatment and certain dysfunctional household environments, can affect the development of a child in a variety of different ways. This multitude of developmental changes may subsequently produce compounding harmful effects on the child's life and increase acutely maladaptive outcomes, including adolescent suicidal behavior. This study uses data collected from 2007 to 2012 for 64,329 Florida Department of Juvenile Justice youth (21.67 % female, 42.88 % African American, and 15.37 % Hispanic) to examine the direct and indirect effects of adverse childhood experiences on suicide attempts. Using a generalized structural equation model, the effects of adverse childhood experience scores are estimated on suicidal behavior through pathways of certain aspects of a child's personality development (aggression and impulsivity), as well as adolescent problem behaviors (school difficulties and substance abuse). The results show that a large proportion of the relationship between childhood adversity and suicide is mediated by the aforementioned individual characteristics, specifically through the youth's maladaptive personality development. These results suggest that, if identified early enough, the developmental issues for these youth could potentially be addressed in order to thwart potential suicidal behavior.

    Brachytherapy has been proved to be an effective method for the purpose of increasing radiation dose to the tumor and reducing the dose to the surrounding normal tissue. In head and neck cancer, the rationale of brachytherapy is as follows; Firstly, early small lesion is radiocurative and the major cause of failure is local recurrence. Secondly, it can diminish evidently the dose to the normal tissue especially masseteric muscle and salivary gland. Thirdly, the anatomy of head and neck is suitable to various technique of brachytherapy. On background of accumulated experience of LDR iridium brachytherapy of head and neck cancer for the last 15 years, the author reviewed the history of radioisotope therapy, the characteristics of radionuclides, and some important things in the method, clinical technique and treatment planning. The author analyzed the clinical result of 185 cases of head and neck cancer treated in the Korea Cancer Center Hospital. Finally the future prospect of brachytherapy of head and neck cancer is discussed

    To provide an alternative device for immobilization of the head while easing claustrophobia and improving comfort, an "open-face" thermoplastic mask was evaluated using video-based optical surface imaging (OSI) and kilovoltage (kV) X-ray radiography. A three-point thermoplastic head mask with a precut opening and reinforced strips was developed. After molding, it provided sufficient visible facial area as the region of interest for OSI. Using real-time OSI, the head motion of ten volunteers in the new mask was evaluated during mask locking and 15minutes lying on the treatment couch. Using a nose mark with reference to room lasers, forced head movement in open-face and full-head masks (with a nose hole) was compared. Five patients with claustrophobia were immobilized with open-face masks, set up using OSI and kV, and treated in 121 fractions, in which 61 fractions were monitored during treatment using real-time OSI. With the open-face mask, head motion was found to be 1.0 ± 0.6 mm and 0.4° ± 0.2° in volunteers during the experiment, and 0.8 ± 0.3 mm and 0.4° ± 0.2° in patients during treatment. These agree with patient motion calculated from pre-/post-treatment OSI and kV data using different anatomical landmarks. In volunteers, the head shift induced by mask-locking was 2.3 ± 1.7 mm and 1.8° ± 0.6°, and the range of forced movements in the open-face and full-head masks were found to be similar. Most (80%) of the volunteers preferred the open-face mask to the full-head mask, while claustrophobic patients could only tolerate the open-face mask. The open-face mask is characterized for its immobilization capability and can immobilize patients sufficiently (< 2 mm) during radiotherapy. It provides a clinical solution to the immobilization of patients with head and neck (HN) cancer undergoing radiotherapy, and is particularly beneficial for claustrophobic patients. This new open-face mask is readily adopted in radiotherapy clinic as a superior alternative to

    A method to correct the measured head-related transfer functions (HRTFs) at low frequency was proposed. By analyzing the HRTFs from the spherical head model at low frequency, it is proved that below the frequency of 400 Hz, magnitude of HRTF is nearly constant and the phase is a linear function of frequency both for the far and near field. Therefore, if the HRTFs above 400 Hz are accurately measured by experiment, it is able to correct the HRTFs at low frequency by the theoretical model. The results of calculation and subjective experiment show that the feasibility of the proposed method.

    Background Persons living with HIV (PLHIV) must adhere optimally to antiretroviral therapy (ART) on a daily basis and for their lifetime to maintain an undetectable viral load, allowing them to preserve their health. Taking advantage of the opportunity that information and communication technologies provide to broaden intervention modalities and intensify clinical follow-up, a virtual nursing intervention consisting of four interactive computer sessions was developed to empower PLHIV to manage their ART and symptoms optimally. Compared with other types of information and communication technologies-assisted interventions such as text messages, HIV Treatment, Virtual Nursing Assistance and Education (VIH-TAVIE) requires a certain degree of active engagement on the part of the user to develop and strengthen the self-management skills to optimize adherence. After the intervention’s impact on ART adherence was measured quantitatively, a qualitative study was undertaken to describe how users experience the intervention. Understanding how PLHIV perceive being assisted asynchronously by a virtual nurse was of particular interest. Objective The objective of the study was to explore and describe how PLHIV experience VIH-TAVIE, that is, receiving customized asynchronous accompaniment via a virtual nurse. Methods A qualitative study was conducted with 26 PLHIV (20 men, 6 women) who received all four VIH-TAVIE sessions. Participants had been diagnosed with HIV 14 years earlier on average and had been on ART for a mean period of 10 years. The sessions lasted 20-30 minutes each and were received two weeks apart. They are hosted by a virtual nurse who engages the user in a self-management skills-learning process for the purpose of treatment adherence. Semistructured interviews were conducted lasting 30-40 minutes to get participants to share their experience of the intervention through personal stories and what they thought and felt during their participation. Data were analyzed

    The pattern of uptake of bone marrow specific radio-sup(99m)Tc sulfur colloid and the pattern of uptake of bone mineral specific radio-sup(99m)Tc pryophosphate may be valuable in assessing bone vascularity in diseases suspected of causing impaired blood supply, or indicate the presence of reactive bone formation. The low energy of the technetium label has been shown to be superior to /sup 18/F and /sup 85/Sr, and leads to greater imaging detail on the scans. Femoral head scanning with mineral and/or marrow specific radionuclides offers the clinician a method of evaluating the status of the femoral head and possibly an early diagnosis of avascular necrosis before roentgenographic changes occur. This study, which reports on a 5-year experience using radionuclide scanning to assess femoral head vascularity, begins with baseline or normal studies followed by variations of the normal pattern. Typical scan patterns of hip pathology described above are also presented.

    This study examines aspects of case managers' perceived personal growth in their work with consumers. Using a sample of 98 case managers, the psychometric properties of a brief self-report measure of personal growth of case managers were examined. The Case Manager Personal Growth Scale (CMPG) showed good reliability and construct validity as evidenced by negative correlations with scores on professional burnout and positive correlations with personal accomplishment and job satisfaction scores. CMPG scores were unrelated to social desirability scores or caseload size and positively related to age and tenure in the mental health system. Results suggest the strong relevance of the construct of personal growth for case managers.

    Although evidence is mounting that personalized music has beneficial effects for long-term care residents with dementia, little research has examined the effects of personalized music for the majority of persons with dementia living at home. These individuals live at home with care partners who may also benefit from having music that is personalized for their loved one. Using the Music & Memory SM program of personalized playlists delivered via iPod Shuffles®, the current study examined the effects of the Music & Memory program for persons with dementia by using the Bath Assessment of Subjective Quality of Life in Dementia scale and a Music Listening Experience Scale developed for this study. We also administered three scales that captured care partner experiences. Transcripts of the Bath Assessment of Subjective Quality of Life in Dementia administrations at the beginning of the study and 3 months later, plus interviews about the Music & Memory program, were then analyzed using the interpretive phenomenological analysis method. Themes about the Music & Memory program and life living with dementia for from diagnosed persons and their care partners are discussed.

    To explore the effect that treatment-related commuting has on carers of patients with head and neck cancer. Semi-structured interviews, thematically analysed, with 31 carers. Treatment-related commuting had a considerable impact on carers of patients with head and neck cancer, both in practical terms (economic costs, disruption) and also in psychological terms. Many carers of patients with head and neck cancer described becoming distressed by their commute. Some carers from large urban cities appeared to have hidden commuting burdens. Some carers respond to commuting stress by 'zoning out' or becoming 'like zombies'. Treatment-related travel for head and neck cancer can have significant practical and psychological impacts. Health professionals should be aware of the impacts that commuting can have on head and neck caregivers. Health services may be able to take practical steps, such as providing subsidized parking, to address head and neck carergivers' difficulties. Copyright © 2017 Elsevier Ltd. All rights reserved.

    There are limited nonlaboratory soccer head impact biomechanics data. This is surprising given soccer's global popularity. Epidemiological data suggest that female college soccer players are at a greater concussion injury risk than their male counterparts. Therefore, the purposes of our study were to quantify head impact frequency and magnitude during women's soccer practices and games in the National Collegiate Athletic Association and to characterize these data across event type, playing position, year on the team, and segment of game (first and second halves). Head impact biomechanics were collected from female college soccer players (n = 22; mean ± SD age = 19.1 ± 0.1 yr, height = 168.0 ± 3.5 cm, mass = 63.7 ± 6.0 kg). We employed a helmetless head impact measurement device (X2 Biosystems xPatch) before each competition and practice across a single season. Peak linear and rotational accelerations were categorized based on impact magnitude and subsequently analyzed using appropriate nonparametric analyses. Overall, women's college soccer players experience approximately seven impacts per 90 min of game play. The overwhelming majority (~90%) of all head impacts were categorized into our mildest linear acceleration impact classification (10g-20g). Interestingly, a higher percentage of practice impacts in the 20g-40g range compared with games (11% vs 7%) was observed. Head impact biomechanics studies have provided valuable insights into understanding collision sports and for informing evidence-based rule and policy changes. These have included changing the football kickoff, ice hockey body checking ages, and head-to-head hits in both sports. Given soccer's global popularity, and the growing public concern for the potential long-term neurological implications of collision and contact sports, studying soccer has the potential to impact many athletes and the sports medicine professionals caring for them.

  9. Head Rotation Detection in Marmoset Monkeys

    Science.gov (United States)

    Simhadri, Sravanthi

    Head movement is known to have the benefit of improving the accuracy of sound localization for humans and animals. Marmoset is a small bodied New World monkey species and it has become an emerging model for studying the auditory functions. This thesis aims to detect the horizontal and vertical rotation of head movement in marmoset monkeys. Experiments were conducted in a sound-attenuated acoustic chamber. Head movement of marmoset monkey was studied under various auditory and visual stimulation conditions. With increasing complexity, these conditions are (1) idle, (2) sound-alone, (3) sound and visual signals, and (4) alert signal by opening and closing of the chamber door. All of these conditions were tested with either house light on or off. Infra-red camera with a frame rate of 90 Hz was used to capture of the head movement of monkeys. To assist the signal detection, two circular markers were attached to the top of monkey head. The data analysis used an image-based marker detection scheme. Images were processed using the Computation Vision Toolbox in Matlab. The markers and their positions were detected using blob detection techniques. Based on the frame-by-frame information of marker positions, the angular position, velocity and acceleration were extracted in horizontal and vertical planes. Adaptive Otsu Thresholding, Kalman filtering and bound setting for marker properties were used to overcome a number of challenges encountered during this analysis, such as finding image segmentation threshold, continuously tracking markers during large head movement, and false alarm detection. The results show that the blob detection method together with Kalman filtering yielded better performances than other image based techniques like optical flow and SURF features .The median of the maximal head turn in the horizontal plane was in the range of 20 to 70 degrees and the median of the maximal velocity in horizontal plane was in the range of a few hundreds of degrees per

    2013-10-01

    Impairment of language ability, aphasia, can cause barriers to communication and hence impact on participation in many life situations. This study aimed to describe and explore how persons with aphasia following stroke experience engaging in everyday occupations. Six persons from Southwest Finland who had aphasia due to stroke one to four years previously were interviewed for the study. A modified form of the empirical phenomenological psychological method was used for data analysis. Three main characteristics of experiences of engaging in everyday occupations were identified: (1) encountering new experiences in everyday occupations, (2) striving to handle everyday occupations and (3) going ahead with life. The participants had experienced an altering life-world. Engagement in occupations affected their perceptions of competence and identity, and experiences of belonging and well-being. It was also through engagement in everyday occupations that they had discovered and learnt to handle changes in their everyday life. Aphasia can have a long-term impact on engagement in everyday occupations and participation in society, but conversely, engagement in meaningful occupations can also contribute to adaptation to disability and life changes. Aphasia can have a long-term impact on engagement in everyday occupations and participation in society. Health care professionals need to determine what clients with aphasia think about their occupations and life situations in spite of difficulties they may have verbalizing their thoughts. Experiences of engaging in meaningful occupations can help clients with aphasia in reconstructing their life stories, thereby contributing to adaptation to disability and life changes.

    Recently, the nature of personality disorders and their relationship with normal personality traits has received extensive attention. The five-factor model (FFM) of personality, consisting of the personality traits neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness, is one of the proposed models to conceptualize personality disorders as maladaptive variants of continuously distributed personality traits. The present study examined the phenotypic and genetic association between borderline personality and FFM personality traits. Data were available for 4403 monozygotic twins, 4425 dizygotic twins, and 1661 siblings from 6140 Dutch, Belgian, and Australian families. Broad-sense heritability estimates for neuroticism, agreeableness, conscientiousness, extraversion, openness to experience, and borderline personality were 43%, 36%, 43%, 47%, 54%, and 45%, respectively. Phenotypic correlations between borderline personality and the FFM personality traits ranged from .06 for openness to experience to .68 for neuroticism. Multiple regression analyses showed that a combination of high neuroticism and low agreeableness best predicted borderline personality. Multivariate genetic analyses showed the genetic factors that influence individual differences in neuroticism, agreeableness, conscientiousness, and extraversion account for all genetic liability to borderline personality. Unique environmental effects on borderline personality, however, were not completely shared with those for the FFM traits (33% is unique to borderline personality). Borderline personality shares all genetic variation with neuroticism, agreeableness, conscientiousness, and extraversion. The unique environmental influences specific to borderline personality may cause individuals with a specific pattern of personality traits to cross a threshold and develop borderline personality.

    Recent epidemiological research has revealed that gender differences exist in concussion incidence but no study has investigated why females may be at greater risk of concussion. Our purpose was to determine whether gender differences existed in head-neck segment kinematic and neuromuscular control variables responses to an external force application with and without neck muscle preactivation. Forty (20 females and 20 males) physically active volunteers participated in the study. The independent variables were gender, force application (known vs unknown), and force direction (forced flexion vs forced extension). The dependent variables were kinematic and EMG variables, head-neck segment stiffness, and head-neck segment flexor and extensor isometric strength. Statistical analyses consisted of multiple multivariate and univariate analyses of variance, follow-up univariate analyses of variance, and t-tests (P Gender differences existed in head-neck segment dynamic stabilization during head angular acceleration. Females exhibited significantly greater head-neck segment peak angular acceleration (50%) and displacement (39%) than males despite initiating muscle activity significantly earlier (SCM only) and using a greater percentage of their maximum head-neck segment muscle activity (79% peak activity and 117% muscle activity area). The head-neck segment angular acceleration differences may be because females exhibited significantly less isometric strength (49%), neck girth (30%), and head mass (43%), resulting in lower levels of head-neck segment stiffness (29%). For our subject demographic, the results revealed gender differences in head-neck segment dynamic stabilization during head acceleration in response to an external force application. Females exhibited significantly greater head-neck segment peak angular acceleration and displacement than males despite initiating muscle activity earlier (SCM only) and using a greater percentage of their maximum head-neck segment

    To assess the relationship between personal and romantic partner's experiences of stressful life events and depression during pregnancy, and the social moderators of this relationship, among 296 young couples with low incomes from urban areas. We recruited couples who were expecting a baby from four ob/gyn and ultrasound clinics in southern Connecticut; women were ages 14-21 and male partners were 14+. We analyzed self-reports of stressful events in the previous six months, depression in the past week and current interpersonal social supports. To determine the influence of personal and partner experiences of stressful events on depression, we used multilevel dyadic models and incorporated interaction terms. We also used this model to determine whether social support, family functioning and relationship satisfaction moderated the association between stressful events and depression. Experiences of stressful life events were common; 91.2% of couples had at least one member report an event. Money, employment problems, and moving were the most common events. Personal experiences of stressful life events had the strongest association with depression among men and women; although partner experiences of stressful life events were also significantly associated with depression among women. Social support, family functioning, and romantic relationship satisfaction significantly buffered the association between personal and partner stressful events and depression. Interventions that improve relationships, support systems, and family functioning may reduce the negative impact of stressors, experienced both personally and by a romantic partner, on the emotional well-being of young expectant parents.

    The aim of this study was to describe the partners' perceptions, understanding, and personal experiences of early menopause and menopausal therapy in women with breast cancer. A questionnaire study was completed by 50 partners of women with diagnoses of breast cancer, recruited via outpatient clinics and the community. Descriptive statistics and χ tests were applied. Most (68%) of the partners perceived hot flushes as the meaning of menopause. Most (60%) partners perceived that loss of sexuality was the key problem/fears about being menopausal. Partners perceived that exercise (72%) and reducing stress (64%) were most effective in alleviating symptoms of menopause. Most partners reported that they did not understand the risks/benefits of hormone therapy (50%), bioidentical hormones (90%), and herbal therapies (84%). The general practitioner was considered the best source of information on menopause (68%). Partners expected menopause to affect a women's everyday life and relationships with family and partner and, particularly, to cause intermittent stress on the relationship (66%) and to decrease libido or sexual interest (64%). Forty-four percent of partners reported that there was some difficulty in communication/discussion about menopause with family and partners. This pilot study highlights (1) the lack of understanding of menopause and menopausal therapies that partners of women with breast cancer have, (2) the personal experience of having a female partner with breast cancer, and (3) the partners' attitudes and responses toward menopause in women with breast cancer.

    The primary purposes of this study were to (1) compare the characteristics of childhood experiences of parental rearing patterns in China reported by patients with borderline personality disorder (BPD), patients with other personality disorders and patients without personality disorders; (2) identify the reported parental rearing patterns associated with BPD in China; and (3) determine whether these patterns differ for males and females. One hundred and fifty-two patients with BPD, 79 patients with other personality disorders and 55 patients without Axis II diagnoses were administered the Chinese version of the McLean Screening Instrument for BPD and completed the Egna Minnen av Barndoms Uppfostran (EMBU), a self-report measure of childhood parental rearing patterns. Parental rearing patterns reported by the BPD group were characterized by less emotional warmth, and greater punishment, rejection and control than patterns reported by the other two groups. Within the BPD group, males were more likely than females to report parental punishment, rejection and control. Paternal punishment, low maternal emotional warmth and female gender predicted BPD diagnosis. Negative parental rearing patterns appear to contribute to the development of BPD in China and vary with the gender of the child. Maternal emotional warmth may be a protective factor against BPD. © 2013 International Union of Psychological Science.

  5. Psychosocial consequences of head injury in children and adolescents: implications for rehabilitation.

    Science.gov (United States)

    Livingston, M G; McCabe, R J

    1990-01-01

    Studies measuring psychosocial outcome in children and adolescents have shown that head injury leads to cognitive impairment which is directly related to the severity of injury in those with very severe head injury. Psychiatric disorders are also related to the severity of injury but here the relationship suggests that mediating factors are involved. No specific pattern of post-traumatic psychological/psychiatric dysfunction emerges from the studies, but it is clear that, as with adults, psychosocial recovery lags behind physical. Head injury affects the functioning of the young person in the family, at school, and within the wider community, often resulting in a secondary handicap of low self-esteem. The multitude of deficits which are a consequence of severe head injury present a challenge for rehabilitation specialists. A multi-disciplinary, multi-specialist, and multi-agency response is required. As a result, families are often presented with a bewildering array of treatments and programmes at different agencies. A case manager can be helpful in ensuring the appropriate use of available resources and can be the one professional in charge of a coordinating case record.

    2013-10-01

    The objectives are to compare and contrast the head and neck trauma experience in Iraq and Afghanistan and to identify trauma lessons learned that are applicable to civilian practice. A retrospective review of one head and neck surgeon's operative experience in Iraq and Afghanistan was performed using operative logs and medical records. The surgeon's daily operative log book with patient demographic data and operative reports was reviewed. Also, patient medical records were examined to identify the preoperative and postoperative course of care. The head and neck trauma experiences in Iraq and Afghanistan were very different, with a higher percentage of emergent cases performed in Iraq. In Iraq, only 10% of patients were pretreated at a facility with surgical capabilities. In Afghanistan, 93% of patients were pretreated at such facilities. Emergent neck exploration for penetrating neck trauma and emergent airway surgery were more common in Iraq, which most likely accounted for the increased perioperative mortality also seen in Iraq (5.3% in Iraq vs. 1.3% in Afghanistan). Valuable lessons regarding soft tissue trauma repair, midface fracture repair, and mandible fracture repair were learned. The head and neck trauma experiences in Iraq and Afghanistan were very different, and the future training for mass casualty trauma events should reflect these differences. Furthermore, valuable head and neck trauma lessons learned in both war zones are applicable to the civilian practice of trauma. Level 4.

    The case is reported of a 47-year old female suffering from the exploding head syndrome. This syndrome consists of a sudden awakening due to a loud noise shortly after falling asleep, sometimes accompanied by a flash of light. The patient is anxious and experiences palpitations and excessive sweating. Most patients are more than fifty years of age. Further investigations do not reveal any abnormality. The pathogenesis is unknown, and no therapy other than reassurance is necessary.

  8. Optimization of an Image-Based Talking Head System

    Kang Liu

    2009-01-01

    Full Text Available This paper presents an image-based talking head system, which includes two parts: analysis and synthesis. The audiovisual analysis part creates a face model of a recorded human subject, which is composed of a personalized 3D mask as well as a large database of mouth images and their related information. The synthesis part generates natural looking facial animations from phonetic transcripts of text. A critical issue of the synthesis is the unit selection which selects and concatenates these appropriate mouth images from the database such that they match the spoken words of the talking head. Selection is based on lip synchronization and the similarity of consecutive images. The unit selection is refined in this paper, and Pareto optimization is used to train the unit selection. Experimental results of subjective tests show that most people cannot distinguish our facial animations from real videos.

    Exploding head syndrome is characterized by the perception of loud noises during sleep-wake or wake-sleep transitions. Although episodes by themselves are relatively harmless, it is a frightening phenomenon that may result in clinical consequences. At present there are little systematic data on exploding head syndrome, and prevalence rates are unknown. It has been hypothesized to be rare and to occur primarily in older (i.e. 50+ years) individuals, females, and those suffering from isolated sleep paralysis. In order to test these hypotheses, 211 undergraduate students were assessed for both exploding head syndrome and isolated sleep paralysis using semi-structured diagnostic interviews: 18.00% of the sample experienced lifetime exploding head syndrome, this reduced to 16.60% for recurrent cases. Though not more common in females, it was found in 36.89% of those diagnosed with isolated sleep paralysis. Exploding head syndrome episodes were accompanied by clinically significant levels of fear, and a minority (2.80%) experienced it to such a degree that it was associated with clinically significant distress and/or impairment. Contrary to some earlier theorizing, exploding head syndrome was found to be a relatively common experience in younger individuals. Given the potential clinical impacts, it is recommended that it be assessed more regularly in research and clinical settings. © 2015 European Sleep Research Society.

This paper focuses on the design of humanoid robot head, which is divided into three steps to achieve. The first step is to solve the uncanny valley about humanoid robot, to find and avoid the relationship between human being and robot; the second step is to solve the association between human face and robot head; compared with human being and robots, we analyze the similarities and differences and explore the same basis and mechanisms between robot and human analyzing the Facial Action Coding System (FACS, which guides us to achieve humanoid expressions. On the basis of the previous two steps, the third step is to construct a robot head; through a series of experiments we test the robot head, which could show some humanoid expressions; through human-robot interaction, we find people are surprised by the robot head expression and feel happy.

    Full Text Available BACKGROUND: When we talk to one another face-to-face, body gestures accompany our speech. Motion tracking technology enables us to include body gestures in avatar-mediated communication, by mapping one's movements onto one's own 3D avatar in real time, so the avatar is self-animated. We conducted two experiments to investigate (a whether head-mounted display virtual reality is useful for researching the influence of body gestures in communication; and (b whether body gestures are used to help in communicating the meaning of a word. Participants worked in pairs and played a communication game, where one person had to describe the meanings of words to the other. PRINCIPAL FINDINGS: In experiment 1, participants used significantly more hand gestures and successfully described significantly more words when nonverbal communication was available to both participants (i.e. both describing and guessing avatars were self-animated, compared with both avatars in a static neutral pose. Participants 'passed' (gave up describing significantly more words when they were talking to a static avatar (no nonverbal feedback available. In experiment 2, participants' performance was significantly worse when they were talking to an avatar with a prerecorded listening animation, compared with an avatar animated by their partners' real movements. In both experiments participants used significantly more hand gestures when they played the game in the real world. CONCLUSIONS: Taken together, the studies show how (a virtual reality can be used to systematically study the influence of body gestures; (b it is important that nonverbal communication is bidirectional (real nonverbal feedback in addition to nonverbal communication from the describing participant; and (c there are differences in the amount of body gestures that participants use with and without the head-mounted display, and we discuss possible explanations for this and ideas for future investigation.

    The aim of this study was to gain insight into experiences and reflections of persons with amyotrophic lateral sclerosis and relatives concerning the peer group rehabilitation programme "More Life - Less Illness". This qualitative study used the Interpretive Description methodology with Symbolic Interactionism as the analytical framework. Eighteen programme participants representing persons with amyotrophic lateral sclerosis (n = 8) and relatives (n = 10) were included. Data consisted of individual interviews and participant observation. The analysis revealed two categorical themes, "Sense of Community Building" and "Understanding my ALS", which represented the participants' experiences and reflections on peer group rehabilitation. Through the analysis, it became apparent that "Sense of Community Building" gave rise to an increased and personalised understanding of amyotrophic lateral sclerosis among the participants. As a part of the continuous processing of the knowledge gained, "Facing Facts" and "Retaining Normality" appeared as subthemes regarding the participants' ability to live a less dependent and more meaningful life. This study of peer group rehabilitation for persons with amyotrophic lateral sclerosis and relatives indicates that programme participation leads to positive experiences in terms of living a shared meaningful life despite severe disability. The findings may guide practice to develop longitudinal peer group rehabilitation programmes with joint inclusion of persons with amyotrophic lateral sclerosis and relatives. Implications for Rehabilitation Peer group rehabilitation may facilitate an increased and personalised understanding of what it means to live with amyotrophic lateral sclerosis. A programme design with six months of sequential sessions enables a continuous processing of shared experiences and gained knowledge. Joint participation of persons with amyotrophic lateral sclerosis and their relatives supports both their internal

    Recent studies have proposed that a high rate of acceleration onset, i.e. high jerk, during a low-speed vehicle collision increases the risk of whiplash injury by triggering inappropriate muscle responses and/or increasing peak head acceleration. Our goal was to test these proposed mechanisms at realistic jerk levels and then to determine how collision jerk affects the potential for whiplash injuries. Twenty-three seated volunteers (8 F, 15 M) were exposed to multiple experiments involving perturbations simulating the onset of a vehicle collision in eyes open and eyes closed conditions. In the first experiment, subjects experienced five forward and five rearward perturbations to look for the inappropriate muscle responses and 'floppy' head kinematics previously attributed to high jerk perturbations. In the second experiment, we independently varied the jerk ( approximately 125 to 3 000 m s(-3)) and acceleration ( approximately 0.65 to 2.6 g) of the perturbation to assess their effect on the electromyographic (EMG) responses of the sternocleidomastoid (SCM), scalene (SCAL) and cervical paraspinal (PARA) muscles and the kinematic responses of the head and neck. In the first experiment, we found neither inappropriate muscle responses nor floppy head kinematics when subjects had their eyes open, but observed two subjects with floppy head kinematics with eyes closed. In the second experiment, we found that about 70% of the variations in the SCM and SCAL responses and about 95% of the variations in head/neck kinematics were explained by changes in perturbation acceleration in both the eyes open and eyes closed conditions. Less than 2% of the variation in the muscle and kinematic responses was explained by changes in perturbation jerk and, where significant, response amplitudes diminished with increasing jerk. Based on these findings, collision jerk appears to have little or no role in the genesis of whiplash injuries in low-speed vehicle crashes.

    There is increasing interest in the use of commercial movies in nursing education, or "cinenurducation". There is a need for educational interventions which target mental health nurses' attitudes towards people with borderline personality disorder. To investigate and evaluate the experience and effects of attendance at a screening of the movie Ida's Diary, a first-person account of living with borderline personality disorder. Mixed methods design comprising a within-subjects AB longitudinal survey, and a qualitative analysis of participant-generated data and researcher field notes from a World Café discussion group. One university in Scotland. N = 66 undergraduate and postgraduate mental health nursing and counselling students. Participants completed measures of cognitive and emotional attitudes towards, and knowledge about, people with borderline personality disorder before and after one of two film screenings. We conducted a World Café discussion group after the second screening. Resulting data were subject to a qualitative thematic analysis. Quantitative analysis revealed a five-factor cognitive and a single-factor emotional attitude structure. Cognitive-attitudinal items related to treatment deservingness and value of mixed treatment approaches improved across iterations. Total knowledge score did not change, but one item about borderline personality disorder as a precursor to schizophrenia received considerably more incorrect endorsement post-screening. Qualitative analysis revealed five themes: Facilitation and inhibition of learning; promotion but not satiation of appetite for knowledge; challenging existing understanding; prompting creativity and anxiety; and initiating thinking about the bigger picture. Participants found the film thought provoking; it increased their appetite for knowledge. Findings suggest that screening should be delivered in conjunction with more didactic information about borderline personality disorder. Copyright © 2018

    The implication of dysphagia for people treated nonsurgically for head and neck cancer (HNC) and its detrimental effects on functioning and quality of life has been well documented. To date, however, there has been a paucity of research on the effects of dysphagia following HNC on carers, independent of the consequences of a gastrostomy. The objective of this qualitative study was to report on the experiences of carers of people with dysphagia (non-gastrostomy dependent) following nonsurgical treatment for HNC and to identify the support needs of this group. A purposive, maximum-variation sampling technique was adopted to recruit 12 carers of people treated curatively for HNC since 2007. Each participated in an in-depth interview, detailing their experience of caring for someone with dysphagia and the associated impact on their life. Thematic analysis was adopted to search the transcripts for key phases and themes that emerged from the discussions. Analysis of the transcripts revealed four themes: (1) dysphagia disrupts daily life, (2) carers make adjustments to adapt to their partner's dysphagia, (3) the disconnect between carers' expectations and the reality of dysphagia, and (4) experiences of dysphagia-related services and informal supports. Carers generally felt ill-prepared for their role in dysphagia management. The qualitative methodology successfully described the impact of dysphagia on the everyday lives of carers, particularly in regard to meal preparation, social events, and family lifestyle. Clinicians should provide adequate and timely training and support to carers and view carers as copartners in dysphagia management.

  18. How to tell a happy from an unhappy schizotype: personality factors and mental health outcomes in individuals with psychotic experiences

    Directory of Open Access Journals (Sweden)

    Letícia O. Alminhana

    Full Text Available Objective: It is unclear why some individuals reporting psychotic experiences have balanced lives while others go on to develop mental health problems. The objective of this study was to test if the personality traits of harm avoidance, self-directedness, and self-transcendence can be used as criteria to differentiate healthy from unhealthy schizotypal individuals. Methods: We interviewed 115 participants who reported a high frequency of psychotic experiences. The instruments used were the Temperament and Character Inventory (140, Structured Clinical Interview for DSM-IV, and the Oxford-Liverpool Inventory of Feelings and Experiences. Results: Harm avoidance predicted cognitive disorganization (β = 0.319; t = 2.94, while novelty seeking predicted bipolar disorder (β = 0.136, Exp [β] = 1.146 and impulsive non-conformity (β = 0.322; t = 3.55. Self-directedness predicted an overall decrease in schizotypy, most of all in cognitive disorganization (β = -0.356; t = -2.95 and in impulsive non-conformity (β = -0.313; t = -2.83. Finally, self-transcendence predicted unusual experiences (β = 0.256; t = 2.32. Conclusion: Personality features are important criteria to distinguish between pathology and mental health in individuals presenting high levels of anomalous experiences (AEs. While self-directedness is a protective factor, both harm avoidance and novelty seeking were predictors of negative mental health outcomes. We suggest that the impact of AEs on mental health is moderated by personality factors.

    The purpose of the present experiments was to investigate an immediate effect of head x-irradiation on the secretion of adrenaline and noradrenaline by the adrenal medulla. When the dogs were irradiated with 200 or 800 R of x-rays to their heads under pentobarbital anesthesia, the majority of the animals showed no stimulation of the adrenal medulla but the minority showed a slight but definite increase in the secretion of adrenaline, the peak being attained within 60 min after exposure.

    To provide an alternative device for immobilization of the head while easing claustrophobia and improving comfort, an “open‐face” thermoplastic mask was evaluated using video‐based optical surface imaging (OSI) and kilovoltage (kV) X‐ray radiography. A three‐point thermoplastic head mask with a precut opening and reinforced strips was developed. After molding, it provided sufficient visible facial area as the region of interest for OSI. Using real‐time OSI, the head motion of ten volunteers in the new mask was evaluated during mask locking and 15 minutes lying on the treatment couch. Using a nose mark with reference to room lasers, forced head movement in open‐face and full‐head masks (with a nose hole) was compared. Five patients with claustrophobia were immobilized with open‐face masks, set up using OSI and kV, and treated in 121 fractions, in which 61 fractions were monitored during treatment using real‐time OSI. With the open‐face mask, head motion was found to be 1.0 ± 0.6 mm and 0.4° ± 0.2° in volunteers during the experiment, and 0.8 ± 0.3 mm and 0.4° ± 0.2° in patients during treatment. These agree with patient motion calculated from pre‐/post‐treatment OSI and kV data using different anatomical landmarks. In volunteers, the head shift induced by mask‐locking was 2.3 ± 1.7 mm and 1.8° ± 0.6°, and the range of forced movements in the open‐face and full‐head masks were found to be similar. Most (80%) of the volunteers preferred the open‐face mask to the full‐head mask, while claustrophobic patients could only tolerate the open‐face mask. The open‐face mask is characterized for its immobilization capability and can immobilize patients sufficiently (face mask is readily adopted in radiotherapy clinic as a superior alternative to the standard full‐head mask.

    To compare standing head posture measurements between patients with nontraumatic neck pain (NP) and pain-free individuals. Single-blind (assessor) cross-sectional study. Hospital and general community. Consecutive patients (n=40) with chronic nontraumatic NP and age- and sex-matched pain-free participants (n=40). Not applicable. Three angular measurements: the angle between C7, the tragus of the ear, and the horizontal; the angle between the tragus of the ear, the eye, and the horizontal; and the angle between the inferior margins of the right and the left ear and the horizontal were calculated through the digitization of video images. NP patients were found to have a significantly smaller angle between C7, the tragus, and the horizontal, resulting in a more forward head posture than pain-free participants (NP, mean +/- SD, 45.4 degrees +/-6.8 degrees ; pain-free, mean +/- SD, 48.6 degrees +/-7.1 degrees ; P50y) revealed an interaction, with a statistically significant difference in head posture for younger participants with NP compared with younger pain-free participants (NP, mean +/- SD, 46.1 degrees +/-6.7 degrees ; pain-free, mean +/- SD, 51.8 degrees +/-5.9 degrees ; P.05; CI for the difference between groups, -4.9 degrees -4.2 degrees ). No other differences were found between patients and pain-free participants. Younger patients with chronic nontraumatic NP were shown to have a more forward head posture in standing than matched pain-free participants. However, the difference, although statistically significant, was perhaps too small to be clinically meaningful.

    In two experiments we examined a number of related factors postulated to influence head-up display (HUD) performance. We addressed the benefit of reduced scanning and the cost of increasing the number of elements in the visual field by comparing a superimposed HUD with an identical display in a head-down position in varying visibility conditions. We explored the extent to which the characteristics of HUD symbology support a division of attention by contrasting conformal symbology (which links elements of the display image to elements of the far domain) with traditional instrument landing system (ILS) symbology. Together the two experiments provide strong evidence that minimizing scanning between flight instruments and the far domain contributes substantially to the observed HUD performance advantage. Experiment 1 provides little evidence for a performance cost attributable to visual clutter. In Experiment 2 the pattern of differences in lateral tracking error between conformal and traditional ILS symbology supports the hypothesis that, to the extent that the symbology forms an object with the far domain, attention may be divided between the superimposed image and its counterpart in the far domain.

    Breastfeeding confers important health benefits to both infants and their mothers, but rates are low in the United Kingdom and other developed countries despite widespread promotion. This study examined the relationships between personal and vicarious experience of infant feeding, self-efficacy, the theory of planned behaviour variables of attitudes and subjective norm, and the likelihood of breastfeeding at 6-8 weeks post-natally. A prospective questionnaire study of both first-time mothers (n = 77) and experienced breastfeeders (n = 72) recruited at an antenatal clinic in South East England. Participants completed a questionnaire at 32 weeks pregnant assessing personal and vicarious experience of infant feeding (breastfeeding, formula-feeding, and maternal grandmother's experience of breastfeeding), perceived control, self-efficacy, intentions, attitudes (to breastfeeding and formula-feeding), and subjective norm. Infant feeding behaviour was recorded at 6-8 weeks post-natally. Multiple linear regression modelled the influence of vicarious experience on attitudes, subjective norm, and self-efficacy (but not perceived control) and modelled the influence of attitude, subjective norm, self-efficacy, and past experience on intentions to breastfeed. Logistic regression modelled the likelihood of breastfeeding at 6-8 weeks. Previous experience (particularly personal experience of breastfeeding) explained a significant amount of variance in attitudes, subjective norm, and self-efficacy. Intentions to breastfeed were predicted by subjective norm and attitude to formula-feeding and, in experienced mothers, self-efficacy. Breastfeeding at 6 weeks was predicted by intentions and vicarious experience of formula-feeding. Vicarious experience, particularly of formula-feeding, has been shown to influence the behaviour of first-time and experienced mothers both directly and indirectly via attitudes and subjective norm.

    Head tilt is one of the most characteristic and enduring symptoms produced by hemilabyrinthectomy and is compensated by the central nervous system with time. In order to study the central mechanisms of compensation of the head tilt, it is first necessary to understand how it is produced. However, its mechanism remains unknown. Experiments were performed in cats to examine whether the direct vestibulocollic pathways are responsible for the head tilt, as suggested by some authors. Hemilabyrinthectomies produced a characteristic head tilt in cats in which the medial and/or one lateral vestibulospinal tracts (VSTs) had been interrupted. The lesions of the medial VST did not influence the preexisting head tilt produced by hemilabyrinthectomies. These results suggest that the head tilt produced by hemilabyrinthectomies does not depend on the activity of the VSTs.

    Health care providers frequently struggle to develop wise applications of theoretical knowledge. As a nurse studying traditional approaches in ethics while simultaneously volunteering in Haiti, I wrestled with the notion of justice in the midst of radical material inequities. Paul Farmer, physician and anthropologist, provides an analytic perspective for health care providers who work in poor and underserved countries by expanding the liberation theology of the 1970s to include social applications. Analyzing my past experiences in Haiti using Farmer's methodology provided insight into my successes and failures and prompted me to search for personal and professional reasons to provide care for the poor in the future. This type of reflection is essential for health care providers who work with the underserved, regardless of their religion or the country in which they work.

    Traumatic brain injury caused by drop and traffic accidents is an important reason for children's death and disability. Recently, the computer finite element (FE) head model has been developed to investigate brain injury mechanism and biomechanical responses. Based on CT data of a healthy 3-year-old child head, the FE head model with detailed anatomical structure was developed. The deep brain structures such as white matter, gray matter, cerebral ventricle, hippocampus, were firstly created in this FE model. The FE model was validated by comparing the simulation results with that of cadaver experiments based on reconstructing the child and adult cadaver experiments. In addition, the effects of skull stiffness on the child head dynamic responses were further investigated. All the simulation results confirmed the good biofidelity of the FE model.

    The illnesses of celebrity patients always receive more attention from the general public than those of ordinary patients. With regard to cancer, this fact has helped to spread information about the four major malignancies: breast cancer, prostatic cancer, lung cancer and colorectal cancer. Head and neck cancer, on the other hand, is still not well recognised by the lay public, although the risk factors are similar to those of lung cancer. It was the objective of this analysis to identify cases of celebrity patients, the description of which could help to increase awareness of head and neck cancer, its symptoms and risk factors. The Internet and medical literature databases were searched for celebrity patients who had suffered from head and neck cancer. The search revealed numerous famous head and neck cancer patients. However, only seven cases were documented well in the medical literature. Among the identified persons were one emperor, two United States presidents, a legendary composer, a world-renowned medical doctor, an outstanding athlete and an extraordinary entertainer. In spite of their exclusive position in society, these patients did not have a better prognosis compared with ordinary patients of their time. Only two of the group experienced long term survival and only one was cured. None of these influential figures used their influence to fund research or to promote knowledge about their respective diseases. The identified cases could help increase public awareness of head and neck cancer. Similar to activities in other oncologic fields, current celebrity head and neck cancer patients should be encouraged to discuss their diseases openly, which could have a positive effect on public health.

    Impairments of speech and language are important consequences of head injury as they compromise interaction between the patient and others. A large spectrum of communication deficits can occur. There are few reports in the literature of aphasia following closed head injury despite the common presentation of closed head injury. Herein we report two cases of closed head injuries with differing forms of aphasia. We discuss their management and rehabilitation and present a detailed literature review on the topic. In a busy acute surgical unit one can dismiss aphasia following head injury as behaviour related to intoxication. Early recognition with prolonged and intensive speech and language rehabilitation therapy yields a favourable outcome as highlighted in our experience. These may serve as a reference for clinicians faced with this unusual outcome.

    Visual cues from persons with impairments may trigger stereotypical generalisations that lead to prejudice and discrimination. The main objective of this pilot study is to examine whether visual stimuli of impairment activate latent prejudice against disability and whether this connection can be counteracted with priming strategies. In a field experiment, participants were asked to rate photographs showing models with mental impairments, wheelchair users with paraplegia, and persons without any visible impairment. Participants should appraise the models with regard to several features (e.g. communicativeness, intelligence). One hundred participants rated 12 photo models yielding a total of 1183 observations. One group of participants was primed with a cover story introducing visual perception of impairment as the study's gist, while controls received neutral information. Photo models with mental impairments were rated lowest and models without visible impairment highest. In participants who did not have prior contacts with persons with impairments, priming led to a levelling of scores of models with and without impairment. Prior contacts with persons with impairments created similar effects as the priming. Unexpectedly, a pattern of converse double discrimination to the disadvantage of men with mental impairments was revealed. Signs of stereotypical processing of visual cues of impairment have been found in participants of the Swiss general population. Personal contact with persons with impairments as well as priming participants seems to reduce stereotyping.

    The purpose of this study was to examine cerebral blood flow in the frontal cortex area during personality self-rating tasks. Our two hypotheses were (1) cerebral blood flow varies based on personality rating condition and (2) cerebral blood flow varies based on the personality traits. This experiment measured cerebral blood flow under 3 personal computer rating conditions and 2 questionnaire conditions. Comparing the rating conditions, the results of the t-test indicated that cerebral blood flow was higher in the questionnaire condition than it was in the personal computer condition. With respect to the Big Five, the result of the correlation coefficient, that is, cerebral blood flow during a personality rating task, changed according to the trait for agreeableness. The results of the analysis of the 5-cluster on individual differences indicated that certain personality traits were related to the factors that increased or decreased cerebral blood flow. An analysis of variance indicated that openness to experience and Behavioural Activation System-drive was significant given that participants with high intellectual curiosity were motivated in this experiment, thus, their cerebral blood flow may have increased. The significance of this experiment was that by employing certain performance measures we could examine differences in physical changes based on personality traits. © 2018 International Union of Psychological Science.

Interview participants were asked to reflect upon their work-related experience with cancer by answering two specific questions: (1) What advice would you give someone who has been newly diagnosed with head and neck cancer? (2) What advice would you give to employers of these people? Data were gathered through 10 individual semi-structured in-depth interviews with HNC clinic patients at a regional cancer center's head and neck clinic in Ontario, Canada. A constant comparative method of theme development was used. Codes identified in and derived from the data were discussed by research team members until consensus was reached. Codes with similar characteristics were grouped together and used to develop overarching themes. Work-related advice for peers focused on personal self-care and interactions within workplaces. Work-related advice to employers focused on demonstrating basic human values as well as the importance of communication. The study results suggest HNC clinic patients should be proactive with employers and help to set reasonable expectations and provide a realistic plan for work to be successfully completed. HNC clinic patients should develop communication skills to effectively disclose their cancer and treatment to employers. In this exploratory study, HNC clinic patients' advice was solution-focused underscoring the importance of self-care and pro-active communication and planning with employers. Employers were advised to demonstrate core human values throughout all phases of the work disability episode beginning at diagnosis.

    Motivated by the discovery of segmental epithelial coeloms, or "head cavities," in elasmobranch embryos toward the end of the 19th century, the debate over the presence of mesodermal segments in the vertebrate head became a central problem in comparative embryology. The classical segmental view assumed only one type of metamerism in the vertebrate head, in which each metamere was thought to contain one head somite and one pharyngeal arch, innervated by a set of cranial nerves serially homologous to dorsal and ventral roots of spinal nerves. The non-segmental view, on the other hand, rejected the somite-like properties of head cavities. A series of small mesodermal cysts in early Torpedo embryos, which were thought to represent true somite homologs, provided a third possible view on the nature of the vertebrate head. Recent molecular developmental data have shed new light on the vertebrate head problem, explaining that head mesoderm evolved, not by the modification of rostral somites of an amphioxus-like ancestor, but through the polarization of unspecified paraxial mesoderm into head mesoderm anteriorly and trunk somites posteriorly.

    Mathematical phantoms are essential for the development and early stage evaluation of image reconstruction algorithms in x-ray computed tomography (CT). This note offers tools for computer simulations using a two-dimensional (2D) phantom that models the central axial slice through the FORBILD head phantom. Introduced in 1999, in response to a need for a more robust test, the FORBILD head phantom is now seen by many as the gold standard. However, the simple Shepp-Logan phantom is still heavily used by researchers working on 2D image reconstruction. Universal acceptance of the FORBILD head phantom may have been prevented by its significantly higher complexity: software that allows computer simulations with the Shepp-Logan phantom is not readily applicable to the FORBILD head phantom. The tools offered here address this problem. They are designed for use with Matlab®, as well as open-source variants, such as FreeMat and Octave, which are all widely used in both academia and industry. To get started, the interested user can simply copy and paste the codes from this PDF document into Matlab® M-files.

    Full Text Available In this paper, we seek for the factors of formation of attitudes of primary school teachers towards inclusion of children who due to some sensory, bodily, mental disability or social deprivation have the need for additional support in development and learning. Research on attitudes towards inclusive education of children with special needs so far indicates that teachers of regular schools 'hesitate' in accepting children with special needs, stating as a reason the fact that they do not feel competent enough to work with them. However, the increase in teacher readiness to work with these children can be seen from the projects for the inclusion of these children that educate the teachers and envisage the support of the school expert team. This study was conducted with the aim of determining whether teacher's experience - either private or professional - with persons with disabilities distinguishes the respondents who exhibit more favourable attitudes towards inclusive education of these children from those with less favourable attitudes. The sample consisted of 105 teachers from five regular primary schools at the territory of Belgrade, 44.2% of whom declared that they had professional experience in working with students with special needs, while 40% of respondents had private experience with persons with developmental disabilities. The results (ANOVA indicate that professional experience with working with children with special needs does not significantly affect the formation and changing of attitudes of teachers of regular schools towards inclusive education. On the other hand, private experience with persons with developmental disabilities has a significant influence both on the attitude towards inclusion as a whole and towards all its components (cognitive, conative, the feeling of competence. Based on the obtained results, implications for the development of the curriculum for educating teachers for working with children with developmental

    Although being personal in relationships with service users is commonly described as an important aspect of the way that professionals help people with severe mental problems, this has also been described to bring with it a need to keep a distance and set boundaries. This study aims to explore how professionals working in psychiatric care view being personal in their relationships with users. Qualitative interviews with 21 professionals working in three outpatient psychiatric units, analyzed through thematic analysis. Being personal in their relationships with users was described as something that participants regarded to be helpful, but that also entails risks. Participants described how they balanced being personal by keeping a distance and maintaining boundaries in their relationships based on their "experience-based knowledge" to counter these risks. While these boundaries seemed to play an important part in the way that they act and behave, they were not seen as fixed, but rather as flexible and dynamic. Boundaries could sometimes be transgressed to the benefit of users. Being personal was viewed as something that may be helpful to users, but that also entails risks. Although boundaries may be a useful concept for use in balancing these risks, they should be understood as something complex and flexible.

    ''Buttonholing'' of the radial head through the anterior joint capsule is a known cause of irreducible anterior radial head dislocation associated with Monteggia injuries in pediatric patients. To the best of our knowledge, no report has described an injury consisting of buttonholing of the radial head through the annular ligament and a simultaneous radial head fracture in an adolescent. In the present case, the radiographic findings were a radial head fracture with anterior dislocation and lack of the anterior fat pad sign. Magnetic resonance imaging (MRI) clearly demonstrated anterior dislocation of the fractured radial head through the torn annular ligament. The anterior joint capsule and proximal portion of the annular ligament were interposed between the radial head and capitellum, preventing closed reduction of the radial head. Familiarity with this condition and imaging findings will aid clinicians to make a proper diagnosis and fast decision to perform an open reduction. (orig.)

    The purpose of this article is to review recent literature examining the occurrence of psychotic experiences in normal population and those with personality disorders. Up to 15% of individuals in the general population report some type or degree of psychotic experience. Most of these individuals function adequately, do not require psychiatric treatment and do not receive diagnosis of a psychotic illness. A significant number of individuals diagnosed with borderline personality disorder (25-50%) also report psychotic symptoms. These are not easily differentiated from the psychotic symptoms reported by individuals with schizophrenia, nor are they always transient. However, emerging research has confirmed that individuals with schizotypal personality disorder are dimensionally related to those with schizophrenia and are at an increased risk of transition to psychosis. Psychotic symptoms are best considered as 'trans-diagnostic' entities on a continuum from normal to pathological. There is a large body of evidence for a dimensional relationship between schizotypal personality disorder and schizophrenia. There is also a significant amount of research showing that psychotic symptoms in borderline personality disorder are frequent, nontransient and represent a marker of illness severity. This review highlights the need to move beyond traditional assumptions and categorical boundaries when evaluating psychotic experiences and psychopathological phenomena.

    Psychosocial stressors have been associated with low back pain reporting. However, response to psychosocial risk factors may be dependent on the individual's personality type that, in turn, can affect muscle recruitment and spine loading. This study explores how personality might be associated with spine loading during repetitive lifting performed throughout an entire work shift. Assess spine loading as a function of an individual's personality type during repetitive, long-term exposure to a materials handling tasks. Laboratory experiment where experienced and inexperienced participants performed repetitive, asymmetric lifts at various load and lift frequency levels throughout a series of 8-hour exposure periods. Spine loads were monitored throughout the work period. Twelve novice and 12 experienced materials handlers who were asymptomatic for back pain. Spine compression, anterior-posterior (A/P) shear, and lateral shear at the L5-S1 level. Participants were categorized into personality types based upon the Myers-Briggs personality type indicator. An electromyography-assisted biomechanical model was used to assess spine compression, A/P shear, and lateral shear throughout the exposure period. The results indicate that intuitors had higher shear spinal loading regardless of moment exposure, lift frequency, and time through the work period, compared with the sensor personality type. In addition, higher spine compressive and shear forces occurred in the perceiver personality compared with the judgers' personality trait, regardless of moment and, often, lift frequency. Novice lifters typically experienced greater spine loading. The results suggest that when there exists a personality-job environment mismatch, spinal loading increases via an increase in antagonistic co-contraction. The trends suggest that inherent personality characteristics may play a role in one's motor control strategies when performing a repetitive lifting task.

    Whether, and how, animals move requires them to assess their environment to determine the most appropriate action and trajectory, although the precise way the environment is scanned has been little studied. We hypothesized that head attitude, which effectively frames the environment for the eyes, and the way it changes over time, would be modulated by the environment. To test this, we used a head-mounted device (Human-Interfaced Personal Observation platform - HIPOP) on people moving through three different environments; a botanical garden ('green' space), a reef ('blue' space), and a featureless corridor, to examine if head movement in the vertical axis differed between environments. Template matching was used to identify and quantify distinct behaviours. The data on head pitch from all subjects and environments over time showed essentially continuous clear waveforms with varying amplitude and wavelength. There were three stylised behaviours consisting of smooth, regular peaks and troughs in head pitch angle and variable length fixations during which the head pitch remained constant. These three behaviours accounted for ca. 40 % of the total time, with irregular head pitch changes accounting for the rest. There were differences in rates of manifestation of behaviour according to environment as well as environmentally different head pitch values of peaks, troughs and fixations. Finally, although there was considerable variation in head pitch angles, the peak and trough values bounded most of the variation in the fixation pitch values. It is suggested that the constant waveforms in head pitch serve to inform people about their environment, providing a scanning mechanism. Particular emphasis to certain sectors is manifest within the peak and trough limits and these appear modulated by the distribution of the points where fixation, interpreted as being due to objects of interest, occurs. This behaviour explains how animals allocate processing resources to the

    Full Text Available The present study attempts to investigate the relationship between symptoms of histrionic personality disorder and experiences of child abuse among students of Tabriz Islamic Azad University in 2013-2014. The general aim of this study is to predict histrionic personality disorder in adulthood based on child abuse experiences during childhood. The population of this study include 19599 people among whom 377 were selected through simple random sampling. The instrument of this study includes Millon-3 CASRS questionnaire and child abuse questionnaire. The data was analyzed by Pearson correlation coefficient and multiple regression. The obtained results revealed that there is significant relationship between histrionic personality disorder (independent variable and dimensions of child abuse (dependent variable that includes emotional, neglect, physical, and sexual child abuse. Considering different dimensions of child abuse, neglect of child and sexual child abuse have the most and the least contribution in predicting symptoms of histrionic personality disorder in adulthood. In addition, the results showed that all four dimensions of child abuse can predict symptoms of histrionic personality disorder in adulthood, but ignorance or neglecting child has the most effect and sexual dimension has the least effect in the prediction.

    Evidence-based parenting programmes are recommended for the treatment of child mental health difficulties. Families with complex psychosocial needs show poorer retention and outcomes when participating in standard parenting programmes. The Helping Families Programme (HFP) is a 16-week community-based parenting intervention designed to meet the needs of these families, including families with parental personality disorder. This study aimed to explore the help seeking and participatory experiences of parents with a diagnosis of personality disorder. It further aimed to examine the acceptability of referral and intervention processes for the HFP from the perspectives of (i) clinicians referring into the programme; and (ii) referred parents. Semi-structured interviews were conducted with parents recruited to receive HFP (n = 5) as part of a research case series and the referring NHS child and adolescent mental health service (CAMHS) clinicians (n = 5). Transcripts were analysed using Interpretive Phenomenological Analysis. Four themes were identified for parents: (i) the experience of parenthood, (ii) being a parent affected by personality disorder, (iii) experience of the intervention, and (iv) qualities of helping. Three themes emerged for clinicians: (i) challenges of addressing parental need, (ii) experience of engaging parents with personality disorders and (iii) limited involvement during HFP. Comparison of parent and clinician themes led to the identification of two key interlinked themes: (i) concerns prior to receiving the intervention, and (ii) the challenges of working together without a mutual understanding. This pilot study identifies potentially significant challenges of working with parents affected by personality disorder and engaging them in HFP and other similar interventions. Results have important wider clinical implications by highlighting potential barriers to engagement and participation and providing insights on how these barriers might be

    Almost two-thirds of the 110,000 people living with dementia in Switzerland receive home care from family members. Outreach counselling can reduce the burden for family caregivers and delay nursing home placement. However, little is known of how this works and how caregivers experience the counselling. The Canton of Aargau Alzheimer's Association has been conducting a pilot project to demonstrate the necessity, effectiveness and practicability of outreach counselling in (their canton). As a part of the evaluation of the project this study explored how family members experience the process of caring for a relative with dementia and outreach counselling. Interpretive phenomenology–a qualitative approach–was used to analyse data from interviews with twelve family caregivers. Most family members felt supported in caregiving by outreach counselling. Three aspects of the counselling were especially important to the participants: being understood and taken seriously by the counsellor; receiving answers to their most pressing questions concerning the illness and being supported when difficult decision had to be taken; regaining personal time and learning how to better interact with the person with dementia. Two participants would have wished for more help by the counsellor. To meet the needs of the family members, consultants should have sufficient experience in dementia patient care and should be strongly networked across the local health and welfare system. This study shows that family members can experience outreach counselling as a great support in their caregiving roles.

    A semianalytical model of slug tests, conducted in a completely penetrating well within a radial constant-head boundary, was derived. The model, based on the Cooper et al. (1967) model, estimates the hydraulic conductivity and storage coefficient through the matching of type curves. Type curves of the semianalytical solution were plotted, and the effect of the distance of the radial constant-head boundary is discussed. For different storage coefficients, the critical distances of the effect of the constant-head boundary were determined. The effect of the storage coefficient on the response of the water head in slug tests with a radial constant-head boundary of a certain distance is also shown. To verify the model, laboratory slug-test experiments were carried out using a cylindrical test platform, in which an artificial confined coarse-sand aquifer was built. Pumping tests were also executed using the test platform. The Cooper et al. (1967) model and new semianalytical model were used to analyze measurements; the hydraulic conductivity and storage coefficient determined using the two methods were compared to demonstrate the importance of the radial constant-head boundary. A model considering the inertial effect was also used to analyze the slug-test measurements, and although the water head response did not oscillate greatly, the inertial effect affected the slug-test calculation result. The laboratory experiments indicate that the proposed semianalytical model is reasonable and reliable.

  15. Design verification for reactor head replacement

    2005-01-01

    This paper outlines the challenges of design verification for reactor head replacement for PWR plants and the program for qualification from the prospective of the utility design engineering group. This paper is based on the experience with the design confirmation of four reactor head replacements for two plants, and their interfacing components, parts, appurtenances, and support structures. The reactor head replacement falls under the jurisdiction of the applicable edition of the ASME Section XI code, with particular reference to repair/replacement activities. Under any repair/replacement activities, demands may be encountered in the development of program and plan for replacement due to the vintage of the original design/construction Code and the design reports governing the component qualifications. Because of the obvious importance of the reactor vessel, these challenges take on an added significance. Additional complexities are introduced to the project, when the replacement components are fabricated by vendors different from the original vendor. Specific attention is needed with respect to compatibility with the original design and construction of the part and interfacing components. The program for reactor head replacement requires evaluation of welding procedures, applicable examination, test, and acceptance criteria for material, welds, and the components. Also, the design needs to take into consideration the life of the replacement components with respect to the extended period of operation of the plant after license renewal and other plant improvements. Thus, the verification of acceptability of reactor head replacement provides challenges for development and maintenance of a program and plan, design specification, design report, manufacturer's data report and material certification, and a report of reconciliation. The technical need may also be compounded by other challenges such as widely scattered global activities and organizational barriers, which

    Purpose/Objective Intensity modulated radiation therapy (IMRT) has the potential to deliver dose distributions that decrease normal tissue toxicity while allowing dose escalation to the tumor to improve local control. Methods have been developed to critically assess patient immobilization, treatment planning, dose prescription, and treatment verification in patients with head and neck cancer treated using a commercial IMRT system (Peacock, NOMOS Corp.). This report presents our initial experience with inverse planning optimization and patient setup and immobilization evaluations. Materials and Methods Patients are non-invasively immobilized using a reinforced thermoplastic mask and a custom head support. The treatment planning computed tomography scan is acquired using a dedicated scanner. Targets and normal structures are defined on the treatment planning system. Dose optimization requires the input for each structure of dose limits, spatial margin, and optimization algorithm weight (range from zero to two). The optimization algorithm allows each spatial location to be occupied by only one structure. Applying a spatial margin often causes target and normal structures to overlap, so a structure-by-structure decision is made to determine if the target or the structure occupies overlapping space (target priority). The effect on the dose distribution of modifying the optimization parameters was evaluated for the parotid gland (see Figure 1 for plan identification). Verification of treatment setup and immobilization was conducted by acquiring two portal images each treatment session, one prior to and one after treatment, and comparing the locations of visible bony landmarks on the portal film against positions on a digitally reconstructed radiograph. Both inter- and intra-treatment motion in the cranio-caudal (CC) and anterior-posterior (AP) directions were studied. Results Figure 2 summarizes the compromise made between target coverage and tissue sparing. The plan

    Insect navigation is guided by heading vectors that are computed by path integration. Mammalian navigation models, on the other hand, are typically based on map-like place representations provided by hippocampal place cells. Such models compute optimal routes as a continuous series of locations that connect the current location to a goal. We propose a "heading-vector" model in which head-direction cells or their derivatives serve both as key elements in constructing the optimal route and as the straight-line guidance during route execution. The model is based on a memory structure termed the "shortcut matrix," which is constructed during the initial exploration of an environment when a set of shortcut vectors between sequential pairs of visited waypoint locations is stored. A mechanism is proposed for calculating and storing these vectors that relies on a hypothesized cell type termed an "accumulating head-direction cell." Following exploration, shortcut vectors connecting all pairs of waypoint locations are computed by vector arithmetic and stored in the shortcut matrix. On re-entry, when local view or place representations query the shortcut matrix with a current waypoint and goal, a shortcut trajectory is retrieved. Since the trajectory direction is in head-direction compass coordinates, navigation is accomplished by tracking the firing of head-direction cells that are tuned to the heading angle. Section 1 of the manuscript describes the properties of accumulating head-direction cells. It then shows how accumulating head-direction cells can store local vectors and perform vector arithmetic to perform path-integration-based homing. Section 2 describes the construction and use of the shortcut matrix for computing direct paths between any pair of locations that have been registered in the shortcut matrix. In the discussion, we analyze the advantages of heading-based navigation over map-based navigation. Finally, we survey behavioral evidence that nonhippocampal

    Worldwide trends of increasing dementia prevalence, have put economic and workforce pressures to shifting care for persons with dementia from residential care to home care. We reviewed the effects of the four dominant models of home care delivery on outcomes for community-dwelling persons with dementia. These models are: case management, integrated care, consumer directed care, and restorative care. This narrative review describes benefits and possible drawbacks for persons with dementia outcomes and elements that comprise successful programs. Case management for persons with dementia may increase use of community-based services and delay nursing home admission. Integrated care is associated with greater client satisfaction, increased use of community based services, and reduced hospital days however the clinical impacts on persons with dementia and their carers are not known. Consumer directed care increases satisfaction with care and service usage, but had little effect on clinical outcomes. Restorative models of home care have been shown to improve function and quality of life however these trials have excluded persons with dementia, with the exception of a pilot study. There has been a little research into models of home care for people with dementia, and no head-to-head comparison of the different models. Research to inform evidence-based policy and service delivery for people with dementia needs to evaluate both the impact of different models on outcomes, and investigate how to best deliver these models to maximize outcomes.

    Background and aims: Personality psychology research relies on the notion that humans have a single self that is the result of the individual's thoughts, feelings, and behaviors that can be reliably described (i.e., through traits). People who identify themselves as "multiple" have a system of multiple or alternative, selves, that share the same physical body. This is the first study to explore the phenomenon of multiplicity by assessing the experiences of people who identify themselves as "multiple." Methods: First, an Internet forum search was performed using the terms "multiplicity" and "multiple system." Based on that search, people who identified themselves as multiple were contacted. Interviews were conducted by a consultant psychiatrist, which produced six case vignettes. Results: Multiplicity is discussed on Twitter, Tumblr, Google+ and several other personal websites, blogs, and forums maintained by multiples. According to the study's estimates, there are 200-300 individuals who participate in these forums and believe they are multiple. Based on the six interviews, it appears that multiples have several selves who are relatively independent of each other and constitute the personality's system. Each "resident person" or self, has their own unique behavioral pattern, which is triggered by different situations. However, multiples are a heterogeneous group in terms of their system organization, memory functions, and control over switching between selves. Conclusions: Multiplicity can be placed along a continuum between identity disturbance and dissociative identity disorder (DID), although most systems function relatively well in everyday life. Further research is needed to explore this phenomenon, especially in terms of the extent to which multiplicity can be regarded as a healthy way of coping.

    Traumatic brain injury (TBI) is one of the world's major causes of death and disability. To aid companies in designing safer and improved protective gear and to aid the medical community in producing improved quantitative TBI diagnosis and assessment tools, a multiscale finite element model of the human brain, head and neck is being developed. Recorded impact data from football and hockey helmets instrumented with accelerometers are compared to simulated impact data in the laboratory. Using data from these carefully constructed laboratory experiments, we can quantify impact location, magnitude, and linear and angular accelerations of the head. The resultant forces and accelerations are applied to a fully meshed head-form created from MRI data by Simpleware. With appropriate material properties for each region of the head-form, the Abaqus finite element model can determine the stresses, strains, and deformations in the brain. Simultaneously, an in-vitro cellular TBI criterion is being developed to be incorporated into Abaqus models for the brain. The cell-based injury criterion functions the same way that damage criteria for metals and other materials are used to predict failure in structural materials.

    Results from experiments and numerical modelling of streamer propagation are presented. The 2D hydrodynamic numerical description of the pulsed discharge based on the local ionization and photoionization models adequately describes the streamer shape and dynamics over a wide range of pressures and voltages. This work presents a method for imaging the instantaneous emission distribution in the streamer head. A method for restoring the electrodynamic radius of the streamer head was developed on the basis of the streamer head images that were obtained with subnanosecond exposure time. The electrodynamic radius has been determined as the distance between the maxima of the electric field at the position where the streamer head transforms into the streamer channel. The dependence of the electrodynamic radius on voltage and pressure has been determined. We show that a 2D numerical model using hydrodynamic approximation predicts the streamer characteristics with an accuracy of about 15% in the 0.5-1 atmosphere pressure range and up to 40% in the 0.2-0.3 atmosphere pressure range for a voltage of U from 20 kV up to 40 kV in the 30 and 40 mm discharge gap.

    While emotional difficulties are highly implicated in borderline personality disorder (BPD), the dynamic relationships between emotions and BPD symptoms that occur in everyday life are unknown. The current paper examined the function of negative emotions as they relate to BPD symptoms in real time. Experience sampling methodology with 281 participants measured negative emotions and borderline symptoms, expressed as a spectrum of experiences, five times daily for two weeks. Overall, having a BDP diagnosis was associated with experiencing more negative emotions. Multilevel modeling supported positive concurrent relationships between negative emotions and BPD symptoms. Lagged models showed that even after 3 hours negative emotions and several symptoms continued to influence each other. Therefore, results indicated that negative emotions and BPD symptoms are intricately related; some evidenced long-lasting relationships. This research supports emotion-symptom contingencies within BPD and provides insight regarding the reactivity and functionality of negative emotions in borderline pathology.

    Head injury causes significant morbidity and mortality, and there is contention about which patients to scan. The UK National Health Service Clinical Guideline (CG) 56 provides criteria for selecting patients with clinically important brain injury who may benefit from a head CT scan, while minimising the radiation and economic burden of scanning patients without significant injury. This study aims to audit the documentation of the use of these guidelines in a busy UK trauma hospital and discusses the comparison with an Australian (New South Wales (NSW) ) head injury guideline. A retrospective cohort study of 480 patients presenting with head injury to the emergency department over 2 months was performed. The patient notes were assessed for documentation of each aspect of the clinical guidelines. Criteria were established to assess the utilisation of the CG 56. A database of clinical data was amalgamated with the head CT scan results for each patient. For the UK CG 56, 73% of the criteria were documented, with the least documented being 'signs of basal skull fracture' and 'amnesia of events'. Thirty-two per cent of patients received head CT and of these, 24% (37 patients) were reported to have pathology. Twenty-four patients underwent head CT without clinical justification being documented, none of which had reported pathology on CT. The study shows that the head injury guidelines are not being fully utilised at a major UK trauma hospital, resulting in 5% of patients being exposed to ionising radiation without apparent documented clinical justification. The NSW guideline has distinct differences to the CG 56, with a more complex algorithm and an absence of specific time frames for head CT completion. The results suggest a need for further education and awareness of head injury clinical guidelines.

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

    Human trophy heads from the Wari site of Conchopata (AD 600-1000) are examined to evaluate if recently deceased persons or old corpses were used to make trophy heads and determine if the modifications are standardized. Similarly styled trophy heads may suggest state oversight that ensured uniform modifications, while different styles may suggest that various factions or kin groups prepared them to their own specifications. Other studies often interpret trophy heads as either enemies or ancestors; so, this study addresses that debate by documenting aspects of their identity as revealed through demographic, paleopathological, and trauma data. Results show that "fresh" bodies, not old corpses, were used to make trophies, as evidenced by cutmarks indicating intentional removal of soft tissues. Trophy heads are remarkably standardized; 89% display a hole on the superior of the cranium, apparently a design feature that displays the trophy head upright and facing forward when suspended by a cord. Of the 31 trophy heads, 24 are adolescents/adults and 7 are children, and of the 17 sexed adults, 15 are male and 2 are female. This suggests that adult men and children were favored as trophies. Among 19 observable adult trophy heads, 42% exhibit cranial trauma, suggesting that violence was common among this group. Complementary data on Wari iconography shows warriors wearing trophy heads and Wari deities holding captives and trophy heads. Thus, it is likely that captives (or just their heads) were taken in battles and raids-either secular or ritual-and eventually transformed into trophy heads. (c) 2008 Wiley-Liss, Inc.

    A novel thermo-physiological human head simulator for headgear testing was developed by coupling a thermal head manikin with a thermo-physiological model. As the heat flux at head-site is directly measured by the head manikin, this method provides a realistic quantification of the heat transfer phenomena occurring in the headgear, such as moisture absorption-desorption cycles, condensation, or moisture migration across clothing layers. Before coupling, the opportunities of the head manikin for representing the human physiology were evaluated separately. The evaluation revealed reduced precision in forehead and face temperature predictions under extreme heterogeneous temperature distributions and no initial limitation for simulating temperature changes observed in the human physiology. The thermo-physiological model predicted higher sweat rates when applied for coupled than for pure virtual simulations. After coupling, the thermo-physiological human head simulator was validated using eight human experiments. It precisely predicted core, mean skin, and forehead temperatures with average rmsd values within the average experimental standard deviation (rmsd of 0.20 ± 0.15, 0.83 ± 0.34, and 1.04 ± 0.54 °C, respectively). However, in case of forehead, precision was lower for the exposures including activity than for the sedentary exposures. The representation of the human sweat evaporation could be affected by a reduced evaporation efficiency and the manikin sweat dynamics. The industry will benefit from this thermo-physiological human head simulator leading to the development of helmet designs with enhanced thermal comfort and, therefore, with higher acceptance by users.

    Most science courses, including courses that provide preparation for pre-service K-12 teachers are only taught from a deductive big picture perspective. This method is fine for most abstract learners, but pre- service classroom educators that are being prepared to teach in middle school classrooms will be faced with the challenge of building science content knowledge in students that are concrete learners. For these K-12 students a better pedagogical practice is to use local real-world familiar places, issues and personal experience to connect student learning with more abstract concepts. To make it more likely that teachers have the requisite skills and pedagogical content knowledge to build K- 12 student science concept knowledge and science process skills we have integrated ESSEA modules that connect worldwide issues such as global climate change with local event studies chosen by learners. Some recent examples include how such local events such as landfill fires and suburban sprawl impact the local area's air, land, water and life. Course participants are able to choose a more personal route to understanding how their habits impact the global environment by participating in a three week learning experience called the Lifestyle Project. This experience asks students to incrementally reduce their use of heating or air-conditioning, the amount of waste going to landfills, to conserve electricity, drive less and eat less energy intensively. Pre-post content assessments indicate that students in this course scored significantly higher on post course content assessments and reported that by engaging in personal experience to global scale learning experiences they have a new appreciation for how personal choices impact the global environment and how to use local artifacts and issues to enhance K-12 student learning.

    2006-03-01

    Although head restraints were introduced in the 1960s as a countermeasure for whiplash, their limited effectiveness has been attributed to incorrect positioning. The effect of backset on cervical segmental angulations, which were previously correlated with spinal injury, has not been delineated. Therefore, the practical restraint position to minimize injury remains unclear. A parametric study of increasing head restraint backset between 0 and 140mm was conducted using a comprehensively validated computational model. Head retraction values increased with increasing backset, reaching a maximum value of 53.5mm for backsets greater than 60mm. Segmental angulation magnitudes, greatest at levels C5-C6 and C6-C7, reached maximum values during the retraction phase and increased with increasing backset. Results were compared to a previously published head restraint rating system, wherein lower cervical extension magnitudes from this study exceeded mean physiologic limits for restraint positions rated good, acceptable, marginal, and poor. As head restraint contact was the limiting factor in head retraction and segmental angulations, the present study indicates that minimizing whiplash injury may be accomplished by limiting head restraint backset to less than 60mm either passively or actively after impact.

    To determine whether pinworm infections and head lice infestations spread among children in orphanages, 117 children from 4 orphanages in Busan-si and Ulsan-si, Korea, were examined for enterobiasis and head lice infestation between January and February 2014. The overall rate of Enterobius vermicularis egg positivity was 0.85%, whereas none of the children had head lice infestations. The rate of pinworm infection was much lower among the orphanage children compared to the rates observed in previous studies among kindergarten and primary school students. Moreover, the risk factors for enterobiasis were less frequent among these subjects than previously reported. The personal hygiene and health of the orphanage children were supervised by a regular, employed nurse through a health education program. In conclusion, pinworm infection was efficiently controlled among the children in orphanages, and this might be related to good personal hygiene practices in Korea.

    A survey was conducted to examine how personal experiences affect the interpretation of the meaning of display and control colours on electric control panels (ECPs). In Korea, the red light on ECPs represents a normal state of operation, while the green light represents a stopped state of operation; this appears to contradict the general stereotypes surrounding these colours. The survey results indicated that the participants who had experience in using ECPs interpreted the colour meaning differently from the other participant group. More than half of the experienced participants regarded the coloured displays and controls as they were designed, while most participants in the other group appeared to interpret the colours in accordance with the stereotypes. It is presumed that accidents related to human errors can occur when non-experienced people use the ECPs, which are easily accessible in many buildings. Practitioner Summary: A survey was conducted to investigate how personal experiences affect the interpretation of the function meanings of coloured lights on electrical control panels. It was found that the interpretation varies according to personal experiences, which can induce accidents related to human errors while operating electrical equipment.

  15. Reflective equilibrium and empirical data: third person moral experiences in empirical medical ethics.

    De Vries, Martine; Van Leeuwen, Evert

    2010-11-01

    In ethics, the use of empirical data has become more and more popular, leading to a distinct form of applied ethics, namely empirical ethics. This 'empirical turn' is especially visible in bioethics. There are various ways of combining empirical research and ethical reflection. In this paper we discuss the use of empirical data in a special form of Reflective Equilibrium (RE), namely the Network Model with Third Person Moral Experiences. In this model, the empirical data consist of the moral experiences of people in a practice. Although inclusion of these moral experiences in this specific model of RE can be well defended, their use in the application of the model still raises important questions. What precisely are moral experiences? How to determine relevance of experiences, in other words: should there be a selection of the moral experiences that are eventually used in the RE? How much weight should the empirical data have in the RE? And the key question: can the use of RE by empirical ethicists really produce answers to practical moral questions? In this paper we start to answer the above questions by giving examples taken from our research project on understanding the norm of informed consent in the field of pediatric oncology. We especially emphasize that incorporation of empirical data in a network model can reduce the risk of self-justification and bias and can increase the credibility of the RE reached. © 2009 Blackwell Publishing Ltd.

    2006-01-01

    Purpose: The purpose of this study is to evaluate the impact of 18 F-fluorodeoxyglucose positron emission tomography (Fag-PET) fused with planning computed tomography (CT) on tumor localization, which guided intensity-modulated radiotherapy (Imr) of patients with head-and-neck carcinoma. Methods and Materials: From October 2002 through April 2005, we performed Fag-PET/CT guided Imr for 28 patients with head-and-neck carcinoma. Patients were immobilized with face masks that were attached with five fiducial markers. Fag-PET and planning CT scans were performed on the same flattop table in one session and were then fused. Target volumes and critical organs were contoured, and Imr plans were generated based on the fused images. Results: All 28 patients had abnormal increased uptake in Fag-PET/CT scans. PET/CT resulted in CT-based staging changes in 16 of 28 (57%) patients. PET/CT fusions were successfully performed and were found to be accurate with the use of the two commercial planning systems. Volume analysis revealed that the PET/CT-based gross target volumes (GTVs) were significantly different from those contoured from the CT scans alone in 14 of 16 patients. In addition, 16 of 28 patients who were followed for more than 6 months did not have any evidence of locoregional recurrence in the median time of 17 months. Conclusion: Fused images were found to be useful to delineate GTV required in IMRT planning. PET/CT should be considered for both initial staging and treatment planning in patients with head-and-neck carcinoma

  17. Rectal benzodiazepines for premedication in children. Review and personal experience.

    1987-01-01

    Modern anesthetic techniques have modified the aims of premedication in pediatric practice. Anxiolysis, amnesia and easiness of induction are now the the main targets. This paper reviews both the literature and the personal experience of the authors on the subject. Many authors now prefer a benzodiazepine. Rectal instillation of benzodiazepine in solution avoids the trauma of the intramuscular route and produces a faster and more predictable effect, than suppositories. Diazepam (.1 to .2 mg/kg) and flunitrazepam (40 to 80 micrograms/kg) have been extensively used in this indication. Diazepam's duration of elimination being much longer than that of flunitrazepam, this last drug is preferred by many pediatric anesthetists. Midazolam (.4 to .5 mg/kg) has a much faster onset and shorter duration of action. It should thus be preferred if the environment enables the administration of premedication within 10 to 15 minutes of induction.

    2007-01-01

    This article is part of a working project which assesses Ontario's mental health legislation and practice vis-à-vis international human rights standards. The paper focuses on procedural safeguards provided by the major international human rights instruments in the field of mental health law such as the UN Principles for the Protection of Persons with Mental Illness (MI Principles) and the European Convention on Human Rights as interpreted by the European Human Rights Court. In analysing Ontario's compliance with international standards, the paper will explore some problems arising from the implementation of the legislation with which the author is familiar with from his experience as counsel for the Consent and Capacity Board. The paper aims to generate discussion for potential reforms in domestic legal systems and to provide a methodology to be used as a tool to assess similar mental health legislation in other local contexts.

    Full Text Available Persons affected by leprosy or by disabilities face forms of stigma that have an impact on their lives. This study seeks to establish whether their experiences of stigma are similar, with a view to enabling the two groups of people to learn from each other. Accounts of experiences of the impact of stigma were obtained using in-depth interviews and focus group discussion with people affected by leprosy and by disabilities not related to leprosy. The analysis shows that there are a lot of similarities in impact of stigma in terms of emotions, thoughts, behaviour, and relationships between the two groups. The main difference is that those affected by leprosy tended to frame their situation in medical terms, while those living with disabilities described their situation from a more social perspective. In conclusion, the similarities offer opportunities for interventions and the positive attitudes and behaviours can be modelled in the sense that both groups can learn and benefit. Research that tackles different aspects of stigmatization faced by both groups could lead to inclusive initiatives that help individuals to come to terms with the stigma and to advocate against exclusion and discrimination.

    Globally observed damage at the control rod drive mechanism nozzles in PWR-type reactors (Bugey-3, Oconee 1,2,3 and ANO-1, David Besse) have triggered enhanced inspection of reactor pressure vessel (RPV) head penetrations. In Germany the regulations require a periodic inspection especially of dissimilar welds. Westinghouse has developed an automated measuring system for RPV heads aimed to inspect welded joints at open nozzles of nozzles with thermosleeves. The testing technology with remote controlled robotics is supposed to perform a weld inspection as complete as possible, restraints result from constructive difficulties for the accessibility. The new gap-scanner DE2008 was qualified at the mock-up and was implemented into the periodic in-service inspection of Neckarwestheim-1.

  1. 'Goats that stare at men': dwarf goats alter their behaviour in response to human head orientation, but do not spontaneously use head direction as a cue in a food-related context.

    Recently, comparative research on the mechanisms and species-specific adaptive values of attributing attentive states and using communicative cues has gained increased interest, particularly in non-human primates, birds, and dogs. Here, we investigate these phenomena in a farm animal species, the dwarf goat (Capra aegagrus hircus). In the first experiment, we investigated the effects of different human head and body orientations, as well as human experimenter presence/absence, on the behaviour of goats in a food-anticipating paradigm. Over a 30-s interval, the experimenter engaged in one of four different postures or behaviours (head and body towards the subject-'Control', head to the side, head and body away from the subject, or leaving the room) before delivering a reward. We found that the level of subjects' active anticipatory behaviour was highest in the control condition and decreased with a decreasing level of attention paid to the subject by the experimenter. Additionally, goats 'stared' (i.e. stood alert) at the experimental set-up for significantly more time when the experimenter was present but paid less attention to the subject ('Head' and 'Back' condition) than in the 'Control' and 'Out' conditions. In a second experiment, the experimenter provided different human-given cues that indicated the location of a hidden food reward in a two-way object choice task. Goats were able to use both 'Touch' and 'Point' cues to infer the correct location of the reward but did not perform above the level expected by chance in the 'Head only' condition. We conclude that goats are able to differentiate among different body postures of a human, including head orientation; however, despite their success at using multiple physical human cues, they fail to spontaneously use human head direction as a cue in a food-related context.

    Family caregivers (broadly defined as family and friends) experience multiple concurrent transitions when caring for a person with advanced cancer. To (a) explore the transition experience of family caregivers caring for persons with advanced cancer living in the community, (b) describe potential triggers for transitions, (c) identify what influences this experience, and (d) develop a conceptual framework of their transition experience. Sandelowski and Barroso's methodology for synthesizing qualitative research included (a) a comprehensive search of empirical literature, (b) quality appraisal of qualitative studies, (c) classification of studies, and (d) synthesis of the findings. Literature was sourced from six electronic data bases. Inclusion criteria were as follows: (a) published qualitative studies (and mixed-method designs) of the caregiving experience of family caregivers of community-living persons with advanced cancer at the end of life, (b) participants (caregivers and care recipients) of 18 years of age and above, (c) studies published in English in any country, and (d) studies published between 2004 and 2014. A total of 72 studies were included in the metasynthesis. Family caregivers experience a "life transition" whereby their lives are permanently altered. The participants described the process of redefining normal which consisted of coming to terms with their situation and connecting with others. Outcomes of these processes were as follows: (a) maintaining a sense of personhood, (b) reframing hope, (c) maintaining self-efficacy, (d) finding meaning, and (e) preparing for the death of their care recipient. The findings provide a framework to guide the development of supportive programs and future research.

    Full text: The development of Co-incidence Detection (CD) in gamma camera technology has allowed the use of positron radiopharmaceuticals in clinical practice without dedicated PET facilities. We report our initial experience of this technology in Oncological applications. All patients were administered 200 MBq of F- 18 FDG intravenously in a fasting state, with serum glucose below 8.9 mmol/L., and hydration well maintained. Tomography was performed using an ADAC Solus Molecular Co-incidence Detection (MCD) dual-head gamma camera, 60 minutes after administration and immediately after voiding. Tomography of the torso required up to three collections depending on the length of the patient, with each collection requiring 32 steps of 40 second duration, and a 50% overlap. Tomography of the brain required a single collection with 32 steps of 80 seconds. Patients were scanned in the supine position. An iterative reconstruction algorithm was employed without attenuation correction. All patients had histologically confirmed malignancy. Scan findings were correlated with results of all conventional diagnostic imaging procedures that were pertinent to the evaluation and management of each individual patient`s disease. Correlation with tumour type and treatment status was also undertaken. F-18 FDG uptake as demonstrated by CD-PET was increased in tumour bearing sites. The degree of increased uptake varied with tumour type and with treatment status.

    Gunshot wounds to the head are usually mortal injures. Their frequency has been increasing in the last years because of increasing crime rates. Emergency Computed Tomography (CT) makes a useful tool for depicting bullet course and brain damage, and thus helps plan treatment. It has been investigated on the CT signs of subdural hematoma, lacerocontusive focus, subarachnoid hemorrhage, hemoencephalus, skull bone fracture and thecal hollow and report them as an aid to the neurosurgeon and the radiologist, for best treatment planning, and in an attempt to establish use prognostic criteria. It has been reviewed 23 cases of gunshot injuries to the head studied with CT at the Emergency Unit of Loreto Mare 2048ital in Naples, Italy. Twenty patients were men and 3 women; their mean age was 31 years (range: 18-49). Three women and 2 men had been injured accidentally by wandering bullets, and one case was an attempted suicide; all the other cases resulted from shootings. It was found 22 penetrating gunshot wounds: 13 of them with thecal entry hole and intracranial bullet retention and 9 with an entry and exit hole. One case was a superficial wound. Crash skull fractures were seen in 22 cases and they were fragmented in 12, with overlapping thecal fragments in 4, and with deep fragments in 2 cases. Gunshot wounds to the head are complex and severe traumas with high mortality rates because of both early and late effects and complications. CT provides the neurosurgeon with abundant findings for diagnosis and surgical planning, which may result in improved survival rates. In these patients emergency CT plays a fundamental diagnostic role in depicting brain damage and thus remains the method of choice for thorough, rapid and accurate brain and skull studies, as well as to detect possible injury to the chest and abdomen.

    The main strategy adopted for Lymphatic Filariasis (LF) elimination globally is annual mass drug administration (MDA) for 4 to 6 rounds. At least 65% of the population at risk should be treated in each round for LF elimination to occur. In Kenya, MDA using diethylcarbamazine citrate (DEC) and albendazole data shows declining compliance (proportion of eligible populations who receive and swallow the drugs) levels (85%-62.8%). The present study's aim was to determine the role of personal opinions and experiences in compliance with MDA. This was a retrospective cross-sectional study conducted between January and September 2009 in two districts based on December 2008 MDA round. In each district, one location with high and one with low compliance was selected. Through systematic sampling, nine villages were selected and interviewer-based questionnaires administered to 965 household heads or adult representatives also systematically sampled. The qualitative data were generated from opinion leaders, LF patients with clinical signs and community drug distributors (CDDs) all purposively selected and interviewed. Sixteen focus group discussions (FGDs) were also conducted with single-sex adult and youth male and female groups. Chi square test was used to assess the statistical significance of differences in compliance with treatment based on the records reviewed. The house-to-house method of drug distribution influenced compliance. Over one-quarter (27%) in low compared to 15% in high compliance villages disliked this method. Problems related to size, number and taste of the drugs were more common in low (16.4%) than in high (14.4%) compliance villages. Reasons for failure to take the drugs were associated with compliance (pcompliance villages. Experience of side effects influenced compliance (Pcompliance in both types of villages (p>0.05). Community sensitization on treatment, drugs used, their regimen and distribution method involving all leaders should be strengthened by

    The goal of the present study was to analyze the epidemiology and specific risk factors of traumatic brain injury (TBI) in the Asterix illustrated comic books. Among the illustrated literature, TBI is a predominating injury pattern. A retrospective analysis of TBI in all 34 Asterix comic books was performed by examining the initial neurological status and signs of TBI. Clinical data were correlated to information regarding the trauma mechanism, the sociocultural background of victims and offenders, and the circumstances of the traumata, to identify specific risk factors. Seven hundred and four TBIs were identified. The majority of persons involved were adult and male. The major cause of trauma was assault (98.8%). Traumata were classified to be severe in over 50% (GCS 3-8). Different neurological deficits and signs of basal skull fractures were identified. Although over half of head-injury victims had a severe initial impairment of consciousness, no case of death or permanent neurological deficit was found. The largest group of head-injured characters was constituted by Romans (63.9%), while Gauls caused nearly 90% of the TBIs. A helmet had been worn by 70.5% of victims but had been lost in the vast majority of cases (87.7%). In 83% of cases, TBIs were caused under the influence of a doping agent called "the magic potion". Although over half of patients had an initially severe impairment of consciousness after TBI, no permanent deficit could be found. Roman nationality, hypoglossal paresis, lost helmet, and ingestion of the magic potion were significantly correlated with severe initial impairment of consciousness (p ≤ 0.05).

    Studies in children with Typical Development (TD) and with Autism Spectrum Disorder (ASD) revealed that autism affects the personal space regulation, influencing both its size (permeability) and its changes depending on social interaction (flexibility). Here, we investigate how the nature of social interaction (Cooperative vs. Uncooperative) and the person perspective influence permeability and flexibility of interpersonal distance. Moreover, we tested whether the deficit observed in ASD children, reflects the social impairment (SI) in daily interactions. The stop-distance paradigm was used to measure the preferred distance between the participant and an unfamiliar adult (first-person perspective, Experiment 1), and between two other people (third-person perspective, Experiment 2). Interpersonal distance was measured before and after the interaction with a confederate. The Wing Subgroups Questionnaire was used to evaluate SI in everyday activities, and each ASD participant was accordingly assigned either to the lower (children with low social impairment [low-SI ASD]), or to the higher SI group (children with high social impairment [high-SI ASD]). We observed larger interpersonal distance (permeability) in both ASD groups compared to TD children. Moreover, depending on the nature of social interaction, a modulation of interpersonal distance (flexibility) was observed in TD children, both from the first- and third-person perspective. Similar findings were found in low-SI but not in high-SI ASD children, in Experiment 1. Conversely, in Experiment 2, no change was observed in both ASD groups. These findings reveal that SI severity and a person's perspective may account for the deficit observed in autism when flexibility, but not permeability, of personal space is considered.

    To evaluate whether readout-segmented echo-planar imaging (RS-EPI) diffusion weighted image (DWI) can diminish image distortion in the head and neck area, compared with single-shot (SS)-EPI DWI. We conducted phantom and patient studies using 3 T magnetic resonance imaging (MRI) with a 16-channel coil. For the phantom study, we evaluated distortion and signal homogeneity in gel phantoms. For the patient study, 29 consecutive patients with clinically suspicious parotid lesions were prospectively enrolled. RS-EPI and SS-EPI DWI were evaluated by two independent readers for identification of organ/lesion and distortion, using semiquantitative scales and quantitative scores. Apparent diffusion coefficient (ADC) values and contrast-noise ratios of parotid tumours (if present; n = 15) were also compared. The phantom experiments showed that RS-EPI provided less distorted and more homogeneous ADC maps than SS-EPI. In the patient study, RS-EPI was found to provide significantly less distortion in almost all organs/lesions (p < 0.05), according to both semiquantitative scales and quantitative scores. There was no significant difference in ADC values and contrast-noise ratios between the two DWI techniques. The distortion in DWI was significantly reduced with RS-EPI in both phantom and patient studies. The RS-EPI technique provided more homogenous images than SS-EPI, and can potentially offer higher image quality in the head and neck area. (orig.)

    2009-01-01

    In the summer of 1925, a debutant writer, Aleksandr Beliaev, published a ‘scientific-fantastic story’, which depicted the travails of a severed human head living in a laboratory, supported by special machinery. Just a few months later, a young medical researcher, Sergei Briukhonenko, succeeded in reviving the severed head of a dog, using a special apparatus he had devised to keep the head alive. This paper examines the relationship between the literary and the scientific experiments with severed heads in post-revolutionary Russia, which reflected the anxieties about death, revival, and survival in the aftermath of the 1914–1923 ‘reign of death’ in that country. It contrasts the anguished ethical questions raised by the story with the public fascination for ‘science that conquers death’. PMID:19442924

    A local island divertor (LID) experiment has begun on LHD, with the aims of controlling edge recycling and improving the plasma confinement. The fundamental divertor functions of the LID have been demonstrated in the recent experiments. From the particle flux profile measurements on the LID head it was found that the particles diffusing out from the core region are well guided along the island separatrix to the LID head. Owing to the closed configuration around the LID head, evidence of the high efficient pumping was observed, together with a strong capacity to screen impurities. The first results of edge modeling using the EMC3-EIRENE code are also presented

    2013-01-01

    Background Hope is a psychosocial resource that is essential for the psychological, spiritual, and physical well-being of family members caring for persons with dementia. A significant positive relationship has been found between hope and well-being in family caregivers of persons with dementia living in the community. However, the hope experience of family caregivers of persons living with dementia in long-term care (LTC) facilities has not been explored. The purpose of this study was to explore the hope experience of family caregivers of persons with dementia living in a LTC facility. Methods Twenty-three open-ended face to face interviews were conducted with 13 family caregivers of residents with dementia in a LTC facility. Family was broadly defined to include relatives and friends. Seven of these participants also reflected on their hope in diaries over a two week period. Interview transcripts and journal texts were analyzed using Thorne’s interpretive description approach. Results The over-arching theme was “hope and connection”. Participants lost hope and felt despair when they perceived they were unable to connect with their family member in the LTC facility. They regained their hope when a connection could be made. Several sub-themes were identified including: accepting where we are, living life in the moment, believing in something, standing together, and balancing dual worlds. Conclusions Hope was important and essential for family caregivers of persons with dementia residing in a LTC facility. The overarching theme of “hope and connection” underscores the importance of maintaining relationships and connection between family members and the person in LTC. Given the paucity of hope research conducted within this population, the study findings provide a foundation for future research. PMID:24138640

    While most doctors believe they have a major role to play in breastfeeding promotion, and consider it worthwhile taking time to assist women to continue to breastfeed, it appears that gender and personal breastfeeding experience affect their attitude and confidence concerning breastfeeding issues. As doctors practicing in rural and regional areas may be expected to provide a greater degree of assistance and support for breastfeeding women, their views on these topics are of particular interest. This article reports the results of qualitative interviews with eight GP registrars from rural and regional Australia, and their views about the influence gender and personal experience have on their ability to assist breastfeeding women. The study is part of a larger project investigating the breastfeeding skills and knowledge of GP registrars as a basis for designing a tailored educational breastfeeding resource. This project uses mixed methods and triangulation of data. Semi-structured, one-on-one interviews were conducted with eight GP registrars from southern Queensland, Australia. The participants were chosen so that there were eight unique combinations of age ( or =34), gender (male or female) and breastfeeding experience (self or spouse had breastfed/had not breastfed) to ensure diversity of responses and increase the transferability of results. Demographics were collected from each participant, as well as information about: their attitudes to breastfeeding and to counselling breastfeeding women; their perception of breastfeeding knowledge needs and their confidence assisting breastfeeding women; and prior training about breastfeeding. Transcripts of the recorded interviews were returned to the participants for verification before analysis. Emergent themes were identified both within and between interviews following content analysis. Four male and four female registrars with a mean age of 35 years (range 28-43 years) were recruited. Two participants of each gender

    Spatial distribution of groundwater recharge/discharge fluxes has an important impact on mass and energy exchanges in shallow streambeds. During the last two decades, extensive studies have been devoted to the quantification of one-dimensional (1-D) vertical exchange fluxes. Nevertheless, few studies were conducted to characterize two-dimensional (2-D) heterogeneous flux fields that commonly exist in real-world cases. In this study, we used an iterative ensemble smoother (IES) to quantify the spatial distribution of 2-D exchange fluxes by assimilating hydraulic head and temperature measurements. Four assimilation scenarios corresponding to different potential field applications were tested. In the first three scenarios, the heterogeneous hydraulic conductivity fields were first inferred from hydraulic head and/or temperature measurements, and then the flux fields were derived through Darcy's law using the estimated conductivity fields. In the fourth scenario, the flux fields were estimated directly from the temperature measurements, which is more efficient and especially suitable for the situation that a complete knowledge of flow boundary conditions is unavailable. We concluded that, the best estimation could be achieved through jointly assimilating hydraulic head and temperature measurements, and temperature data were superior to the head data when they were used independently. Overall, the IES method provided more robust and accurate vertical flux estimations than those given by the widely used analytical solution-based methods. Furthermore, IES gave reasonable uncertainty estimations, which were unavailable in traditional methods. Since temperature can be accurately monitored with high spatial and temporal resolutions, the coupling of heat tracing techniques and IES provides promising potential in quantifying complex exchange fluxes under field conditions.

    Personalities are determined by convergent factors, including physical environment, culture, special experience, and heredity. It has been shown that abuse of substance and alcohol among individuals with personality disorders predict criminality (Glenn and Raine, 2014; Hernandez-Avila et al., 2000). Thus, it is important to clarify the relationship between psychological characteristics and valence of criminal practice, even in the population without substance abuse. Here, we focused on a population with military experience in Shaanxi province of China to screen the psychological characteristics and correlate these characteristics to criminal behaviors. The study population included incarcerated veterans, incarcerated civilians, and three groups of military troops with different lengths of active duty history (criminal behavior of incarcerated veterans seem to be unrelated to their military service per se as evidenced by the control groups. Conversely, military service may benefit the personnel characteristics even in the incarcerated veteran population. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    2014-01-01

    Using data (n = 3,790 with 2,119 in the 3-year-old cohort and 1,671 in the 4-year-old cohort) from 353 Head Start centers in the Head Start Impact Study, the only large-scale randomized experiment in Head Start history, this paper examined the impact of Head Start on children’s cognitive and parent-reported social-behavioral outcomes through first grade contingent on the child care arrangements used by children who were randomly assigned to the control group (i.e., parental care, relative/non-relative care, another Head Start program, or other center-based care). A principal score matching approach was adopted to identify children assigned to Head Start who were similar to children in the control group with a specific care arrangement. Overall, the results showed that the effects of Head Start varied substantially contingent on the alternative child care arrangements. Compared to children in parental care and relative/non-relative care, Head Start participants generally had better cognitive and parent-reported behavioral development, with some benefits of Head Start persisting through first grade; in contrast, few differences were found between Head Start and other center-based care. The results have implications regarding the children for whom Head Start is most beneficial as well as how well Head Start compares to other center-based programs. PMID:25329552

    The MAAP4 material creep calculation was compared with the experiments reported by Maile, et al., for a 0.7 m diameter hot leg, with a thickness of 47 mm, which is pressurized to 16.3 MPa and heated to temperatures in excess of 700degC. These experiments showed that the carbon steel hot leg would undergo material creep to a failure state in approximately 1,100 seconds. In addition, the MAAP4 creep calculation was compared with the lower head failure tests performed at the Sandia National Laboratories (SNL). These experiments were performed using scaled models of a typical Reactor Pressure Vessel lower head. The test vessel was fabricated from SA533B1 steel with an inner diameter of 0.91 m and a nominal thickness of 30 mm. The experiments were performed at around 10 MPa internal pressure with various imposed heat flux distributions. The onset of creep was observed to occur between 660degC and 705degC. The MAAP4 model provides a good characterization of the material creep behavior. For the hot leg test benchmark, the key is determining the correct equivalent stress when the stress is multi-axial. A good agreement was obtained when a multiplier of 1.09 to the hoop stress was used. For the lower head failure benchmark, using correct creep properties is important. The SNL test vessel material was fabricated as SA533B1 steel. However, when the experimental vessel material was tested for creep properties it turned out to be significantly weaker than the reactor vessel steel which has the same identification. Also, the material undergoing phase transition and becoming stronger at high temperatures has to be considered for accurate prediction of the failure time. A good agreement was obtained when the creep data of Jeong, et al., was used. (author)

    The site characterization and validation project lasted for five years from 1986 to 1991. It consisted of a number of experiments within the region known as the SCV site. During this period of experimentation a monitoring system was established within the mine for the purpose of measuring the variation of head at a number of locations within and around the site. The system installed was based around a set of equipment known as a Piezomac TM system. In this system there is one central pressure transducer and each borehole interval is connected to it in turn. It can measure up to 55 separate points during each measurement 'cycle'. Monitoring points were either complete boreholes or sections of boreholes isolated by packers. In order to produce reasonable file size, data sets were screened. The results show that the SCV site was always responding to some form of hydrogeological disturbance. Many key tests were performed against changing background trends. This was particularly so of the simulated drift experiment and the large scale crosshole tests. However, some estimates of long term equilibrium heads before and after excavation of the validation drift have been made. Contoured plots of heads before and after show significant reduction of steady state heads as a result of drift excavation. Furthermore contouring the estimated long term drawdowns responding to the simulated drift experiment shows the specific influence of the H zone and the A/B zone. Overall the results of the monitoring show that the mine was a very active hydrogeological environment during the experimentation. Additionally it was often very difficult to clearly identify the causes of such disturbances. (au)

    1998-03-01

    The objective of the USNRC supported Lower Head Failure (LHF) Experiment Program at Sandia National Laboratories is to experimentally investigate and characterize the failure of the reactor pressure vessel (RPV) lower head due to the thermal and pressure loads of a severe accident. The experimental program is complemented by a modeling program focused on the development of a constitutive formulation for use in standard finite element structure mechanics codes. The problem is of importance because: lower head failure defines the initial conditions of all ex-vessel events; the inability of state-of-the-art models to simulate the result of the TMI-II accident (Stickler, et al. 1993); and TMI-II results suggest the possibility of in-vessel cooling, and creep deformation may be a precursor to water ingression leading to in-vessel cooling

Back players, who were often positioned in the open field, were shown to experience elevated levels of head impact exposure relative to players at other positions. The analysis also suggests that practice intensity, which may be influenced by coaching style, may also affect high-magnitude head impact exposure. Future studies should investigate this aspect as a factor affecting head impact exposure. PMID:29037104

    The results and analysis of an experiment for the effective water head in downcomer with 50mm gap size are described. The main objective of the experiment was to clarify the effect of gap size on reflooding in a PWR LOCA. The effective water head in downcomer is the driving force for feeding emergency coolant into the core during reflood phase of a PWR LOCA. Discussions presented here follow those of a previous report in which experimental results and analysis were described for the case of 200mm gap size. Experimental Conditions were: Initial Wall Temperature = 200 -- 300 0 C, Back Pressure = 1 atm., Coolant Temperature = 71 -- 100 0 C, Extraction Water Velocity = 0 -- 2 cm/s, Gap Size = 50 mm. The effective water head history obtained in the experiment was compared with those predicted with Sudo's void fraction correlation. In the prediction, heat input to coolant was calculated from the response of measured wall temperature with heat condition analysis. The experimental results and analysis reveals that: (1) The effects of the gap size and initial wall temperature are evident, (2) The effect of extraction water velocity is negligible, and (3) The predicted history of effective water head is in good agreement with the experimental results except during the transient period in which the effective water head is descreasing.

    To evaluate the risk of self-reported temporomandibular disorder (TMD) pain among adolescents in relation to previous head and/or neck injury. 3,101 enrollees (11 to 17 years of age) of a nonprofit integrated health-care system were interviewed by telephone. Two hundred four cases with self-reported TMD pain and 194 controls without self-reported TMD pain frequency-matched to the cases by age and gender completed standardized in-person interviews and physical examinations in which reports of previous head/neck injuries were recorded. Odds ratio (OR) estimates and 95% confidence intervals (CIs) of the relative risks of TMD pain associated with prior head and/or neck injuries were calculated using logistic regression. A greater proportion of subjects reporting TMD pain (36%) than controls (25%) had a history of head and/or neck injuries (OR = 1.8, 95% CI, 1.1-2.8). In a separate analysis, the presence of TMD based upon the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) was assessed in relation to prior head and/or neck injury. Cases reporting TMD pain and meeting the RDC/TMD criteria for myofascial pain and/or arthralgia or arthritis were 2.0 (CI, 1.0-3.8) times more likely to have had a prior head injury than were controls with neither self-reported nor RDC/TMD pain diagnoses. The results suggest a modest association of prior head injuries with both self-reported and clinically diagnosed TMD pain in adolescents.

    Objective To determine the status of adverse childhood experiences (ACEs) and the association of multiple ACEs with both parental alcoholism and later personal alcohol abuse among Chinese medical students with a view of improving adolescent health and reducing alcohol abuse among them. Methods In this cross-sectional study, 2073 Chinese medical students completed a survey on ten categories of ACEs in Anhui province of China. The association of parental alcoholism with ACEs and personal lcohol abuse was assessed by logistic regression analyses. Results The adjusted odds ratio (OR) for each category of ACEs in the subjects whose parents (either fathers or mothers or oth) had alcohol abuse was 2 to 14 times higher than that inthose with parental alcoholism (P<0.05). Subjects with i-parental alcoholism had the highest likelihood of ACEs. Compared with the subjects without ACEs, the risk of personal alcohol abuse was increased by 2-4-folds in the subjects with ACEs, irrespective of parental alcoholism (P<0.05). The total number of ACEs (ACE score) had a graded relationship to 4 categories of personal alcohol abuse with or without parental alcoholism. The prevalence of personal alcohol abuse among the subjects with parental alcoholism was higher, which was ndependent of ACE scores. Conclusion The prevalence of ACEs is generally serious in China. Efforts should be made to prevent and treat children with ACEs and subsequently to reduce alcohol abuse and later problems.

    This study aimed at understanding the interactional experience between family caregivers and disabled elderly persons supported in a Day Care Center according to the caregiver's perspective. It also aimed at developing a representative theoretical model for the events experienced by such caregiver. The Grounded Theory was used as methodological framework whereas Interactional Symbolism served as the theoretical framework. Observation and interviews were used for data collection. The following phenomenon arose from the results: feeling of support by the Day Care Center, by the strength of the bond with the elderly and by spirituality in order to continue playing the challenging role of a family caregiver for a disabled elderly person. The study made possible to understand that, among these three supporting cornerstones for coping with the burden generated by the family caregiver role, the care model promoted by the Day Care Center was the intervenient variable in the process of improving the quality of life of the family caregiver-disabled elderly person binomial. This allowed the identification of the main category--moving from reclusion to partial freedom: the experience of family caregivers for disabled elderly persons assisted in a Day Care Center.

  13. Trauma-Related Dissociation Is Linked With Maladaptive Personality Functioning

    Full Text Available Background: Extensive research has demonstrated the positive associations among the exposure to traumatic experiences, the levels of dissociation, and the severity of psychiatric symptoms in adults. However, it has been hypothesized in clinical literature that an excessive activation of the dissociative processes following multiple traumatic experiences may jeopardize the psychological and behavioral functioning of the individuals, fostering higher levels of maladaptive personality functioning.Methods: The study involved 322 adult volunteers from Italy. Participants completed measures on traumatic experiences, dissociation, and maladaptive personality traits.Results: The number of traumatic experiences reported by participants were positively associated with dissociation scores and maladaptive personality scores. Mediation analyses showed that dissociation acted as a partial mediator in the relationship between traumatic experiences and overall maladaptive personality functioning. Regression curve analyses showed that the positive association between maladaptive personality functioning and dissociation was stronger among participants with higher exposure to traumatic experiences.Conclusion: Exposure to multiple traumatic experiences may increase the risk for an excessive activation of the dissociative processes, which in turn may generate severe impairments in multiple domains of personality functioning.

    Previous research has shown that in the minds of young adult religious adherents, acquired theology about the extraordinary characteristics of God (e.g., omniscience) coexists with, rather than replaces, an initial concept of God formed by co-option of the person concept. We tested the hypothesis that representational coexistence holds even after extensive experience with Christian theology, as indexed by age. Christian religious adherents ranging in age from 18 to 87 years were asked to evaluate as true or false statements on which core knowledge intuitions about persons and Christian theology about God were consistent (both true or both false) or inconsistent (true on one and false on the other). Results showed, across adulthood, more theological errors in evaluating inconsistent versus consistent statements. Older adults also exhibited slower response times to inconsistent versus consistent statements. These findings show that despite extensive experience, indeed a lifetime of experience for some participants, the Christian theological God concept does not separate from the initial person concept from which it is formed. In fact, behavioral signatures of representational coexistence were not attenuated by experience. We discuss the broader implications of these findings to the acquisition of evolutionarily new concepts.

    A parametric study was conducted to delineate the efficacy of personal protective equipment (PPE), such as ballistic faceshields and advanced combat helmets, in the case of a blast. The propagations of blast waves and their interactions with an unprotected head, a helmeted one, and a fully protected finite element head model (FEHM) were modeled. The biomechanical parameters of the brain were recorded when the FEHM was exposed to shockwaves from the front, back, top, and bottom. The directional dependent tissue response of the brain and the variable efficiency of PPE with respect to the blast orientation were two major results of this study.

    Pediatric head trauma, including abusive head trauma, is a significant cause of morbidity and mortality. The purpose of this research was to identify and evaluate radiologic interpretation errors of head CTs performed on abusive and non-abusive pediatric head trauma patients from a community setting referred for a secondary interpretation at a tertiary pediatric hospital. A retrospective search identified 184 patients <5 years of age with head CT for known or potential head trauma who had a primary interpretation performed at a referring community hospital by a board-certified radiologist. Two board-certified fellowship-trained neuroradiologists at an academic pediatric hospital independently interpreted the head CTs, compared their interpretations to determine inter-reader discrepancy rates, and resolved discrepancies to establish a consensus second interpretation. The primary interpretation was compared to the consensus second interpretation using the RADPEER trademark scoring system to determine the primary interpretation-second interpretation overall and major discrepancy rates. MRI and/or surgical findings were used to validate the primary interpretation or second interpretation when possible. The diagnosis of abusive head trauma was made using clinical and imaging data by a child abuse specialist to separate patients into abusive head trauma and non-abusive head trauma groups. Discrepancy rates were compared for both groups. Lastly, primary interpretations and second interpretations were evaluated for discussion of imaging findings concerning for abusive head trauma. There were statistically significant differences between primary interpretation-second interpretation versus inter-reader overall and major discrepancy rates (28% vs. 6%, P=0.0001; 16% vs. 1%, P=0.0001). There were significant differences in the primary interpretation-second interpretation overall and major discrepancy rates for abusive head trauma patients compared to non-abusive head trauma

    The psychedelic experience (including psychedelic-induced ego dissolution) can effect lasting change in a person's attitudes and beliefs. Here, we aimed to investigate the association between naturalistic psychedelic use and personality, political perspectives, and nature relatedness using an anonymous internet survey. Participants (N = 893) provided information about their naturalistic psychedelic, cocaine, and alcohol use, and answered questions relating to personality traits of openness and conscientiousness (Ten-Item Personality Inventory), nature relatedness (Nature-Relatedness Scale), and political attitudes (one-item liberalism-conservatism measure and five-item libertarian-authoritarian measure). Participants also rated the degree of ego dissolution experienced during their "most intense" recalled psychedelic experience (Ego-Dissolution Inventory). Multivariate linear regression analysis indicated that lifetime psychedelic use (but not lifetime cocaine use or weekly alcohol consumption) positively predicted liberal political views, openness and nature relatedness, and negatively predicted authoritarian political views, after accounting for potential confounding variables. Ego dissolution experienced during a participant's "most intense" psychedelic experience positively predicted liberal political views, openness and nature relatedness, and negatively predicted authoritarian political views. Further work is needed to investigate the nature of the relationship between the peak psychedelic experience and openness to new experiences, egalitarian political views, and concern for the environment.

    Healthy ageing is a concept that concerns older persons' quality of life and is a key factor in promoting well-being. The older population in Thailand is growing. Isan (a region of north-eastern Thailand) has been reported as having one of the most rapidly increasing older populations in the country. In order to care for and promote the health of older people, healthcare providers should understand how healthy ageing is perceived by this target group. Although healthy ageing has been studied in different contexts as well as perspectives, no studies have previously focused on older persons' experiences of healthy ageing from a lifeworld perspective in Isan-Thai. Therefore, the aim of this study is to describe older persons' qualitatively different conceptions of healthy ageing in Isan-Thai culture. A phenomenographic approach with an epistemological base in lifeworld theory was used to disclose the various ways to conceptualize healthy ageing. Individual, qualitative interviews were conducted with 17 people aged 60 and above who live in Isan-Thai. The findings of this study revealed three categories of descriptions: "being independent in dependence," "being at peace," and "being a valuable person." This study also found family members, friends, healthcare providers, and religion important to healthy ageing in the Isan-Thai culture. Understanding how older people conceptualize healthy ageing is valuable for healthcare providers. They can apply these findings regarding healthy ageing in their fieldwork when caring for older people.

    Women's health is an important task in society. The aim of this qualitative study that used a phenomenological approach was to explain women's personal experiences of giving birth in Gonabad city that had positive experiences of giving birth in order to establish quality cares and the related factors of midwifery cares for this physiological phenomenon. The participants were 21 primiparae women who gave a normal and or uncomplicated giving birth in the hospital of Gonabad University of medical sciences. Based on a purposeful approach in-depth interviews were continued to reach data saturation. The data were collected through open and semi-structured interactional in-depth interviews with all the participants. All the interviews were taped, transcribed and then analyzed through a qualitative content analysis method to identify the concepts and themes. Some categories were emerged. A quiet and safe environment was the most urgent need of the most women giving birth. Unnecessary routine interventions that are performed on all women regardless of their needs and should be avoided were considered such as: "absolute rest, establishing vein, frequent vaginal examinations, fasting and early Amniotomy". All the women wanted to take part actively in their giving birth, because they believed it could affect their giving birth. We hope that the women's experiences of giving birth will be a pleasant and enjoyable experience for all the mothers giving birth.

    Effect of exogenous application of mixtures of NAA, Ga and BA to the head in sunflower, after pollination and fertilization, on the mobilization of 14 C-metabolites was studied. Application of such mixtures increased mobilization and altered the pattern of translocation. TIBA applied to the head when the ray florets only had commenced opening also caused an increase in mobilization of 14 C-metabolites. Percent activity in relation to the activity fixed by the leaf increased from 36.8 in control to 63 in TIBA treated head. Field experiments conducted for 2 seasons also confirmed effectiveness of TIBA application in increasing percent seed filling and also 1000 grain weight. In sunflower it was possible to increase the sink capacity by application of growth regulators. (author)

    Lymphangiomas are uncommon benign congenital tumors. Most occur in the head and neck and most lesions present by the age of 2 years. We present our experience with four patients who have lymphangiomas of the head and neck with tongue involvement. First case is a 7-year-old male who has the cystic lymphangioma of left submandibular area. Second a 22-year-old female has a lesion involving the border of right tongue. Third case is the lymphangioma which occur in the right upper lip of a 6-year old male. The last patient is a 28-year old male who fell down and whose right face was swollen up. He had undergone an operation and treated with steroid before. The characteristic appearances of imaging methods were described and all lesions best depicted on T2-weighted images. Our experience indicates that MRI is useful in the diagnosis and treatment planning of lymphangioma.

    Purpose: To fully utilize the technical capabilities of radiation diagnostics and planning, a precise and reproducible method of head fixation is a prerequisite. Method: We have adapted the Vogele-Bale-Hohner (VBH) head holder (Wellhoefer Dosimetrie, Schwarzenbruck, Germany), originally designed for frameless stereotactic operations, to the requirements of external beam radiotherapy. A precise and reproducible head fixation is attained by an individualized vacuum upper-dental cast which is connected over 2 hydraulic arms to an adjustable head- and rigid base-plate. Radiation field and patient alignment lasers are marked on a relocatable clear PVC localization box. Results: The possibility of craniocaudal adjustment of the head plate on the base plate allows the system to adapt to the actucal position of the patient on the raditherapy couch granting tensionless repositioning. The VBH head holder has proven itself to be a precise yet practicable method of head fixation. Duration of mouthpiece production and daily repositioning is comparable to that of the thermoplastic mask. Conclusion: The new head holder is in routine use at our hospital and quite suitable for external beam radiation of patients with tumors of the head and neck. (orig.) [de

    Objective: To evaluate an interactive, video-based system for positioning head and neck patients. Materials and Methods: System hardware includes two B and W CCD cameras (mounted to provide left-lateral and AP-inferior views), zoom lenses, and a PC equipped with a frame grabber. Custom software is used to acquire and archive video images, as well as to display real-time subtraction images revealing patient misalignment in multiple views. Live subtraction images are obtained by subtracting a reference image (i.e., an image of the patient in the correct position) from real-time video. As seen in the figure, darker regions of the subtraction image indicate where the patient is currently, while lighter regions indicate where the patient should be. Adjustments in the patient's position are updated and displayed in less than 0.07s, allowing the therapist to interactively detect and correct setup discrepancies. Patients selected for study are treated BID and immobilized with conventional litecast straps attached to a baseframe which is registered to the treatment couch. Morning setups are performed by aligning litecast marks and patient anatomy to treatment room lasers. Afternoon setups begin with the same procedure, and then live subtraction images are used to fine-tune the setup. At morning and afternoon setups, video images and verification films are taken after positioning is complete. These are visually registered offline to determine the distribution of setup errors per patient, with and without video assistance. Results: Without video assistance, the standard deviation of setup errors typically ranged from 5 to 7mm and was patient-dependent. With video assistance, standard deviations are reduced to 1 to 4mm, with the result depending on patient coopertiveness and the length of time spent fine-tuning the setups. At current levels of experience, 3 to 4mm accuracy is easily achieved in about 30s, while 1 to 3mm accuracy is achieved in about 1 to 2 minutes. Studies

    This article is a comparative study of medical experiments on persons with special needs in Islamic jurisprudence and Arab laws; United Arab Emirates (UAE) law as case study. The current study adopts a comparative analytical and descriptive approach. The conclusion of this study points out that the Convention on the Rights of Persons with Special Needs, ratified by a number of Arab States, including the United Arab Emirates, approves conducting medical experiments on persons with special needs, subject to their free consent. As a result of ratifying this Convention, a number of special laws were enacted to be enforced in the United Arab Emirates. On the other hand, this issue is controversial from an Islamic jurisprudence point of view. One group of jurisprudents permits conducting these experimentations if they are designed to treat the person involved, and prohibits such experimentations for scientific advancement. Other jurisprudents permit conducting medical experimentations on persons with special needs, whether the purpose of such experimentations is treatment of the disabled or achieving scientific advancement. The opinion of this group is consistent with the International Convention and the Arab laws in this respect. However, neither the Convention nor the Arab laws regulate this matter by specific and comprehensive conditions, as addressed by some contemporary scholars. It is recommended that the Convention and the Arab laws adopt these conditions. Additionally, the Convention does not state whether the experimentations may be conducted for the interest of the person with disability or for the purpose of scientific advancement. The text of the Convention is unclear and therefore requires further illumination.

    Tossing a coin is the most elementary Monte Carlo experiment. In a computer the coin is replaced by a pseudo random number generator. It can be shown analytically and by exact enumerations that popular random number generators are not capable of imitating a fair coin: pseudo random coins show more heads than tails. This bias explains the empirically observed failure of some random number generators in random walk experiments. It can be traced down to the special role of the value zero in the ...

    OBJECTIVE--To assess risk factors for important neurosurgical effects in patients who reattend after head injury. DESIGN--Retrospective study. SUBJECTS--606 patients who reattended a trauma unit after minor head injury. MAIN OUTCOME MEASURES--Intracranial abnormality detected on computed tomography or the need for neurosurgical intervention. RESULTS--Five patients died: two from unrelated causes and three from raised intracranial pressure. On multiple regression analysis the only significant predictor for both abnormality on computed tomography (14.4% of reattenders) and the need for operation (5% of reattenders) was vault fracture seen on the skull radiograph (P personality change, and seizures were significantly associated only with abnormality on computed tomography. Headache, dizziness, nausea, and vomiting were common in reattenders but were found to have no independent significance. CONCLUSIONS--All patients who reattend after head injury should undergo computed tomography as at least 14% of scans can be expected to yield positive results. Where this facility is not available patients with predictors for operation should be urgently referred for neurosurgical opinion. Other patients can be readmitted and need referral only if symptoms persist despite symptomatic treatment or there is neurological deterioration while under observation. These patients are a high risk group and should be treated seriously. PMID:8520273

  12. "Where Withstanding is Difficult, and Deserting Even More": Head Nurses’ Phenomenological Description of Intensive Care Units

    2016-01-01

    Full Text Available Introduction: The intensive care unit is one of the specialized units in hospitals where head nurses are responsible for both motivating the personnel and providing high quality care. Understanding of the lived experiences of head nurses could help develop new assumptions of the ICU. The present study was therefore conducted to describe the lived experiences of head nurses working in ICU. Methods: In this phenomenological study, data were collected through unstructured in-depth interviews with 5 ICU head nurses in Northern Iran and then analyzed using 7 steps Colaizzi’s method. Results: Despite the "distressing atmosphere of the ICU", the "difficulty of managing the ICU" and the "difficulty of communication in the ICU", which encourages the "desire to leave the unit" among ICU head nurses, the "desire to stay in the unit" is stronger and head nurses are highly motivated to stay in the unit because the unit "develops a feeling of being extraordinary", "creates an interest in providing complicated care to special patients", "facilitates the spiritual bond", "develops a professional dynamism" and "creates an awareness about the nature of intensive care" among them. Conclusion: According to the result, ICU head nurses are still inclined to work in the unit and achieve success in spite of the problems that persist in working in the ICU. As the individuals’ motivation can be the backbone of organizations, and given that individuals with a high enthusiasm for success are productive, hospital managers can take advantage of this strength in choosing their head nurses.

  13. Calibration with respect to hydraulic head measurements in stochastic simulation of groundwater flow - a numerical experiment using MATLAB

    1994-12-01

    A simulator for 2D stochastic continuum simulation and inverse modelling of groundwater flow has been developed. The simulator is well suited for method evaluation and what-if simulation and written in MATLAB. Conductivity fields are generated by unconditional simulation, conditional simulation on measured conductivities and calibration on both steady-state head measurements and transient head histories. The fields can also include fracture zones and zones with different mean conductivities. Statistics of conductivity fields and particle travel times are recorded in Monte-Carlo simulations. The calibration uses the pilot point technique, an inverse technique proposed by RamaRao and LaVenue. Several Kriging procedures are implemented, among others Kriging neighborhoods. In cases where the expectation of the log-conductivity in the truth field is known the nonbias conditions can be omitted, which will make the variance in the conditionally simulated conductivity fields smaller. A simulation experiment, resembling the initial stages of a site investigation and devised in collaboration with SKB, is performed and interpreted. The results obtained in the present study show less uncertainty than in our preceding study. This is mainly due to the modification of the Kriging procedure but also to the use of more data. Still the large uncertainty in cases of sparse data is apparent. The variogram represents essential characteristics of the conductivity field. Thus, even unconditional simulations take account of important information. Significant improvements in variance by further conditioning will be obtained only as the number of data becomes much larger. 16 refs, 26 figs

    Microsurgical equipment has greatly advanced since the inception of the microscope into the operating room. These advancements have allowed for superior surgical precision and better post-operative results. This study focuses on the use of the Leica HM500 head-mounted microscope for the operating phonosurgeon. The head-mounted microscope has an optical zoom from 2× to 9× and provides a working distance from 300 mm to 700 mm. The headpiece, with its articulated eyepieces, adjusts easily to head shape and circumference, and offers a focus function, which is either automatic or manually controlled. We performed five microlaryngoscopic operations utilizing the head-mounted microscope with successful results. By creating a more ergonomically favorable operating posture, a surgeon may be able to obtain greater precision and success in phonomicrosurgery. Phonomicrosurgery requires the precise manipulation of long-handled cantilevered instruments through the narrow bore of a laryngoscope. The head-mounted microscope shortens the working distance compared with a stand microscope, thereby increasing arm stability, which may improve surgical precision. Also, the head-mounted design permits flexibility in head position, enabling operator comfort, and delaying musculoskeletal fatigue. A head-mounted microscope decreases the working distance and provides better ergonomics in laryngoscopic microsurgery. These advances provide the potential to promote precision in phonomicrosurgery.

    Compared to heading, unintentional head impacts (e.g., elbow to head, head to head, head to goalpost) in soccer are more strongly related to risk of moderate to very severe Central Nervous System (CNS) symptoms. But, most head impacts associated with CNS symptoms that occur in soccer are mild and are more strongly related to heading. We tested for a differential relation of heading and unintentional head impacts with neuropsychological (NP) test performance. Active adult amateur soccer players were recruited in New York City and the surrounding areas for this repeated measures longitudinal study of individuals who were enrolled if they had 5+ years of soccer play and were active playing soccer 6+ months/year. All participants completed a baseline validated questionnaire ("HeadCount-2w"), reporting 2-week recall of soccer activity, heading and unintentional head impacts. In addition, participants also completed NP tests of verbal learning, verbal memory, psychomotor speed, attention, and working memory. Most participants also completed one or more identical follow-up protocols (i.e., HeadCount-2w and NP tests) at 3- to 6-month intervals over a 2-year period. Repeated measures General Estimating Equations (GEE) linear models were used to determine if variation in NP tests at each visit was related to variation in either heading or unintentional head impacts in the 2-week period before testing. 308 players (78% male) completed 741 HeadCount-2w. Mean (median) heading/2-weeks was 50 (17) for men and 26 (7) for women. Heading was significantly associated with poorer performance on psychomotor speed ( p  impacts were not significantly associated with any NP test. Results did not differ after excluding 22 HeadCount-2w with reported concussive or borderline concussive symptoms. Poorer NP test performance was consistently related to frequent heading during soccer practice and competition in the 2 weeks before testing. In contrast, unintentional head impacts incurred

    Recent research has demonstrated a strong relationship between psychotic experiences and suicidal behaviour. No research to date, however, has investigated the role of borderline personality disorder (BPD) in this relationship, despite the fact that BPD is highly comorbid with common mental disorders and is associated with both recurrent suicidal behaviour and psychotic experiences. This paper examined the relationship between psychotic experiences and suicide attempts, including interrelationships with BPD and common mental disorders. We used the 2007 Adult Psychiatric Morbidity Study, a stratified, multistage probability sample of households in England, which recruited a nationally representative sample aged 16 years and older. Participants were assessed for common mental disorders, BPD (clinical and subclinical), suicidal behaviour, and psychotic experiences. Approximately 4% of the total sample (n = 323) reported psychotic experiences. Psychotic experiences were associated with increased odds of suicide attempts in individuals with BPD (OR = 2.23, 95% CI = 1.03-4.85), individuals with a common mental disorder (OR = 2.47, 95% CI = 1.37-4.43), individuals without a common mental disorder (OR = 3.99, 95% CI = 2.47-6.43), and individuals with neither a common mental disorder nor BPD (OR = 3.20, 95% CI = 1.71-5.98). Psychotic experiences are associated with high odds of suicidal behaviour in individuals with and without psychopathology. This relationship is not explained by clinical or subclinical BPD. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  7. Modeling borderline personality disorder based on the neurobehavioral foundation of major personality traits.

    Depue, Richard A; Fu, Yu

    2012-03-01

    Borderline personality disorder (BPD) is an exceedingly complex behavioral phenomenon that is in need of conceptual clarification within a larger model of personality disorders (PDs). The association of personality traits to BPD is discussed initially as a means of introducing a dimensional personality approach to understanding BPD. While this model suggests that PDs emerge at the extremes of personality dimensions, attempts to demonstrate such an association have been empirically disappointing and conceptually unilluminating. Therefore, in this article, we attempt to extend such models by outlining the neurobehavioral systems that underlie major personality traits, and highlight the evidence that they are subject to experience-dependent modification that can be enduring through effects on genetic expression, mainly through processes known as epigenetics. It is through such processes that risk for personality disorder may be modified by experience at any point in development, but perhaps especially during early critical periods of development. We conclude by presenting a multidimensional model of PDs, in general, and BPD, in particular, that relies on the concepts developed earlier in the article. Our goal is to provide a guide for novel clinical conceptualization and assessment of PDs, as well as research on their psychobiological nature and pharmacological treatment.

    Full Text Available Introduction Although the incidence of tuberculosis (TB in Japan has been decreasing yearly, Japan remains ranked as an intermediate-burden country for TB. Objective This study aims to investigate the current situation of head and neck extrapulmonary TB (EPTB diagnosed in our department. Methods We retrospectively reviewed the clinical records of 47 patients diagnosed with EPTB in the head and neck in our department between January 2005 and December 2014. The extracted data included sex and age distribution, development site, chief complaint, presence or absence of concomitant active pulmonary TB (PTB or history of TB, tuberculin skin test (TST results, interferon-gamma release assay (IGRA results, and duration from the first visit to the final diagnosis of EPTB. Results The subjects consisted of 20 men and 27 women, and age ranged from 6 to 84 years. The most common site was the cervical lymph nodes (30 patients, with the supraclavicular nodes being the most commonly affected (60%. Histopathological examination was performed on 28 patients. TST was positive in 9 out of 9 patients and the IGRA was positive in 18 out of 19 patients. We observed concomitant PTB in 15 out of the 47 patients. Mean duration from the first visit to the final diagnosis of EPTB was 56 days. Conclusion The clinical symptoms of TB, especially those in the head and neck region, are varied. Otolaryngologists should be especially aware of the extrapulmonary manifestations of TB to ensure early diagnosis and treatment from the public health viewpoint.

    As the volume of electronically available information grows, relevant items become harder to find. This work presents an approach to personalizing search results in scientific publication databases. This work focuses on re-ranking search results from existing search engines like Solr or ElasticSearch. This work also includes the development of Obelix, a new recommendation system used to re-rank search results. The project was proposed and performed at CERN, using the scientific publications available on the CERN Document Server (CDS). This work experiments with re-ranking using offline and online evaluation of users and documents in CDS. The experiments conclude that the personalized search result outperform both latest first and word similarity in terms of click position in the search result for global search in CDS.

    A multiple inputs-driven realistic facial animation system based on 3-D virtual head for human-machine interface is proposed. The system can be driven independently by video, text, and speech, thus can interact with humans through diverse interfaces. The combination of parameterized model and muscular model is used to obtain a tradeoff between computational efficiency and high realism of 3-D facial animation. The online appearance model is used to track 3-D facial motion from video in the framework of particle filtering, and multiple measurements, i.e., pixel color value of input image and Gabor wavelet coefficient of illumination ratio image, are infused to reduce the influence of lighting and person dependence for the construction of online appearance model. The tri-phone model is used to reduce the computational consumption of visual co-articulation in speech synchronized viseme synthesis without sacrificing any performance. The objective and subjective experiments show that the system is suitable for human-machine interaction.

    Leiomyosarcoma is a rare neoplasm of the head and neck. The purpose of this study was to present our single-institution case series of head and neck leiomyosarcoma and a review of cases in the National Cancer Data Base (NCDB). Patients with head and neck leiomyosarcoma at the University of Pennsylvania and in the NCDB were identified. Demographic characteristics, tumor factors, treatment paradigms, and outcomes were evaluated for prognostic significance. Nine patients with head and neck leiomyosarcoma from the institution were identified; a majority had high-grade disease and cutaneous leiomyosarcoma, with a 5-year survival rate of 50%. Two hundred fifty-nine patients with leiomyosarcoma were found in the NCDB; macroscopic positive margins and high-grade disease were associated with poor prognosis (P < .01), and positive surgical margins were related to adjuvant radiation (P < .001). Head and neck leiomyosarcoma presents at a high grade and is preferentially treated with surgery. Several demographic and tumor-specific factors are associated with outcomes and prognosis. © 2017 Wiley Periodicals, Inc.

    Morton, Patricia M; Turiano, Nicholas A; Mroczek, Daniel K; Ferraro, Kenneth F

    2016-03-12

    Previous research has revealed a link between childhood experiences and adult health, but the mechanisms underlying this relationship are less clear. To elucidate this relationship, we investigated the pathway from childhood misfortune to nonfatal myocardial infarction (MI) via individual differences in personality. Longitudinal data were drawn from the National Survey of Midlife Development in the United States, which sampled 3,032 men and women aged 25-74 years at baseline. Big 5 personality traits and multiple measures of childhood misfortune were used to assess whether personality mediated the effect of childhood misfortune on MI risk. A series of proportional hazards models revealed that neuroticism mediated the effect of additive childhood misfortune on adult MI risk. Childhood misfortune may be formative in the development of personality, which, subsequently, can be consequential to health. These findings highlight the salient roles of early-life experiences and personality to shape health and aging. © The Author 2016.

  1. Head Impact Exposure and Neurologic Function of Youth Football Players.

    2015-08-01

    Football players are subjected to repetitive impacts that may lead to brain injury and neurologic dysfunction. Knowledge about head impact exposure (HIE) and consequent neurologic function among youth football players is limited. This study aimed to measure and characterize HIE of youth football players throughout one season and explore associations between HIE and changes in selected clinical measures of neurologic function. Twenty-two youth football players (11-13 yr) wore helmets outfitted with a head impact telemetry (HIT) system to quantify head impact frequency, magnitude, duration, and location. Impact data were collected for each practice (27) and game (9) in a single season. Selected clinical measures of balance, oculomotor performance, reaction time, and self-reported symptoms were assessed before and after the season. The median individual head impacts per practice, per game, and throughout the entire season were 9, 12, and 252, respectively. Approximately 50% of all head impacts (6183) had a linear acceleration between 10g and 20g, but nearly 2% were greater than 80g. Overall, the head impact frequency distributions in this study population were similar in magnitude and location as in high school and collegiate football, but total impact frequency was lower. Individual changes in neurologic function were not associated with cumulative HIE. This study provides a novel examination of HIE and associations with short-term neurologic function in youth football and notably contributes to the limited HIE data currently available for this population. Whereas youth football players can experience remarkably similar head impact forces as high school players, cumulative subconcussive HIE throughout one youth football season may not be detrimental to short-term clinical measures of neurologic function.

    Introduction Head and neck cancer (HNC) comprises a diverse group of oncological entities, originating from various tissue types and organ localizations, situated in the topographical regions of the head and neck (H&N). This single institution retrospective study was aimed at establishing the HNC patient demographics and categorizing the individual incidence of H&N malignancies, regarding their organ of origin and main histopathological type. Materials and methods All histologically verified cases of HNC from a single tertiary referral center were reviewed in a descriptive retrospective manner. Data sampling period was 47 months. Results Male to female ratio of the registered HNC cases was 3.24:1. The mean age of diagnosis was 63.84 ± 12.65 years, median 65 years. The most common HNC locations include the larynx 30.37% (n = 188), lips and oral cavity 29.08% (n = 180), pharynx 20.03% (n = 124) and salivary glands 10.94% (n = 68), with other locations such as the external nose, nasal cavity and sinuses and auricle and external ear canal harboring a minority of the cases. The main histopathological groups include squamous cell carcinoma 76.74% (n = 475) and adenocarcinoma 6.14% (n = 38), with other malignant entries such as other epithelial malignancies, primary tonsillar, mucosa-associated lymphoid tissue or parenchymal lymphomas, connective tissue neoplasias, neuroendocrine and vascular malignancies diagnosed in a minority of cases. Conclusion Considered to be relatively rare, HNC represents a diverse group of oncological entities with individual and specific demographic characteristics. The reported single institution results appear representative of the national incidence and characteristics of HNC. PMID:28875091

    another medical illness. The gold standard for PNES diagnosis is video electroencephalogram (Video-EEG. PNESs are defined by modern psychiatry as conversion and dissociative disorders but these disorders may coexist with many others psychiatric disorders, including depression, posttraumatic stress disorder, and personality disorders. It is well known that epileptic seizures are a frequent and well-studied complication of traumatic head injury (THI. However, THI may also generate psychic symptoms including PNES. In this paper we describe a patient who developed PNES after THI in a bus accident and received a diagnosis of refractory epilepsy for 24 years until she underwent Video-EEG.

    To assess safety of clinical MRI of the head in patients with implanted model 100, 102, and 103 vagus nerve stimulation (VNS) Therapy Systems (Cyberonics, Inc., Houston, TX) in 3.0 Tesla MRI (GE Healthcare, Milwaukee, WI). The distributions of the radiofrequency B(1) (+)-field produced by the clinically used transmit/receive (T/R) head coil (Advanced Imaging Research Incorporated, Cleveland, OH) and body coil were measured in a head and shoulders phantom. These measurements were supplemented by temperature measurements on the lead tips and the implantable pulse generator (IPG) of the VNS devices in a head and torso phantom with the same two coils. Clinical 3T MRI head scans were then acquired under highly controlled conditions in a series of 17 patients implanted with VNS. Phantom studies showed only weak B(1) (+) fields at the location of the VNS IPG and leads for MRI scans using the T/R head coil. The MRI-related heating on a VNS scanned in vitro at 3T was also found to be minimal (0.4-0.8 degrees C at the leads, negligible at the IPG). The patient MRI examinations were completed successfully without any adverse incidents. No patient reported any heating, discomfort, or any other unusual sensation. Safe clinical MRI head scanning of patients with implanted VNS is shown to be feasible on a GE Signa Excite 3T MRI system using one specific T/R head coil. These results apply to this particular MRI system configuration. Extrapolation or generalization of these results to more general or less controlled imaging situations without supporting data of safety is highly discouraged.

    The vision for dementia-friendly communities is challenged by limited public awareness and stigma about dementia. The study aim was to elicit stakeholder priorities for the message content of an education program to improve dementia awareness among youth; specifically, what do children need to know about dementia? A qualitative inquiry using interviews and focus groups was used. Purposive sampling achieved maximum variation in dementia experience and participant characteristics. Focus groups with Scouts in the community aged 9-12 years old (n = 22) used innovative techniques to explore children's attitudes towards people with dementia. Participants with personal experience of dementia were five people with early-stage dementia; 12 adult primary carers; four non-primary carers; and six grandchildren of a person with dementia. They were asked what is important for children to understand about dementia and what attitudes they may like an education program to confer. Content analysis was performed using NVivo10. Strong themes to emerge were that children need to know the whole truth about dementia; that individuals with dementia are "still people," that it is "not the fault" of the person with dementia; and that dementia is different and typically unpredictable for everyone. Discussions also indicated a need to educate children about ways to relate to a person with dementia, and to appreciate "positives" within a relationship. Children are our future citizens. Developing an education program for children with this message content may be fundamental to de-stigmatizing dementia and laying the foundation to dementia-friendly communities.

    To discuss the representation and organization of information describing persons' lived experience of health from a personal factors perspective in the light of the International Classification of Functioning, Disability and Health, using spinal cord injury as a case in point for disability. The scientific literature was reviewed, discussion rounds conducted, and qualitative secondary analyses of data carried out using an iterative inductive-deductive approach. Conceptual considerations are explicated that distinguish the personal factors perspective from other components of the International Classification of Functioning, Disability and Health. A representation structure is developed that organizes health-related concepts describing the internal context of functioning. Concepts are organized as individual facts, subjective experiences, and recurrent patterns of experience and behavior specifying 7 areas and 211 concept groups. The article calls for further scientific debate on the perspective of personal factors in the light of the International Classification of Functioning, Disability and Health. A structure that organizes concepts in relation to a personal factors perspective can enhance the comprehensiveness, transparency and standardization of health information, and contribute to the empowerment of persons with disabilities. Implications for rehabilitation The present study collected data from scientific literature reviews, discussion rounds and qualitative secondary analyses in order to develop a representation and organization of information describing persons' lived experience of health from a personal factors perspective in the light of the International Classification of Functioning, Disability and Health. The following representation structure for health-related information from a personal factors perspective was developed: (i) Individuals facts (i.e., socio-demographical factors, position in the immediate social and physical context, personal history

  11. Mean 24-hours sympathetic nervous system activity decreases during head-down tilted bed rest but not during microgravity

    Sympathetic nervous system activity is closely related to gravitational stress in ground based experiments. Thus a high activity is present in the standing-up position and a very low activity is observed during acute head-out water immersion. Adjustments in sympathetic activity are necessary to maintain a constant blood pressure during variations in venous return. Head-down tilted bed rest is applied as a model to simulate changes observed during microgravity. The aim of the present study was to test the hypothesis that mean 24-hours sympathetic activity was low and similar during space flight and in ground based observation obtained during long-term head-down tilted bed rest. Forearm venous plasma noradrenaline was measured by a radioenzymatic technique as an index of muscle sympathetic activity and thrombocyte noradrenaline and adrenaline were measured as indices of mean 24-hours sympathoadrenal activity. Previous results have indicated that thrombocyte noradrenaline level has a half-time of 2 days. Thus to reflect sympathetic activity during a specific experiment the study period must last for at least 6 days and a sample must be obtained within 12 hours after the experiment has ended. Ten normal healthy subjects were studied before and during a 14 days head-down tilted bed rest as well as during an ambulatory study period of a similar length. The whole experiment was repeated while the subjects were on a low calorie diet. Thrombocyte noradrenaline levels were studied in 4 cosmonauts before and within 12 hours after landing after more than 7 days in flight. Thrombocyte noradrenaline decreased markedly during the head-down tilted bed rest (pdifferent in cosmonauts and in subjects participating in the head down tilted bed rest study (170± 29% (Mean± SEM) vs. 57± 7%, respectively; presponse to combined effects of a reduced plasma volume and an increased vascular capacity in flight.

    To attain a better understanding of the benefits and barriers faced by persons with multiple sclerosis (MS) in the workplace. Qualitative research methodology comprising a series of semistructured interviews. Community-based setting. Fourteen women and 2 men with MS living in the community who were employed or recently employed at the time of interviews. Not applicable. Accounts of personal experiences related to employment. Four themes emerged: the cost-benefit economy of working; fatigue and cognitive changes; stress in the workplace; and accommodations made to address barriers. Although participants valued work highly, they were also aware of the cost of being employed. The consequences of unemployment or changing jobs were considered negative and appeared stressful. For persons with MS, employment had both costs and significant benefits. Accommodations in the workplace and modifications of roles and responsibilities at home made it possible for individuals to continue working. Health care providers must consider the complexity and timing of decisions by people with MS to continue or leave employment before recommending either action. Identifying critical periods of intervention to stabilize this cost-benefit balance is a critical next step for understanding issues of employment and MS.

    This article evaluates performance tests of the Soviet made GPK heading machine carried out in 4 coal mines in Czechoslovakia (Ostrava-Karvina region and Kladno mines). GPK works in coal seams and rocks with compression strength of 40 to 50 MPa. Dimensions of the tunnel are height 1.8 to 3.8 m and width 2.6 to 4.7 m, tunnel gradient plus to minus 10 degrees. GPK weighs 16 t, its conical shaped cutting head equipped with RKS-1 cutting tools is driven by an electric motor with 55 kW capacity. Undercarriage of the GPK, gathering-arm loader, hydraulic system, electric system and dust supression system (water spraying or pneumatic section) are characterized. Specifications of GPK heading machines are compared with PK-3r and F8 heading machines. Reliability, number of failures, dust level, noise, productivity depending on compression strength of rocks, heading rate in coal and in rocks, energy consumption, performance in inclined tunnels, and cutting tool wear are evaluated. Tests show that GPK can be used to drive tunnels in coal with rock constituting up to 50% of the tunnel crosscut, as long as rock compression strength does not exceed 50 MPa. In rocks characterized by higher compression strength cutting tool wear sharply increases. GPK is characterized by higher productivity than that of the PK-3r heading machine. Among the weak points of the GPK are: unsatisfactory reliability and excessive wear of its elements. (4 refs.) (In Czech)

    Because of the high prevalence of burnout among medical students and its association with professional and personal consequences, the authors evaluated the help-seeking behaviors of medical students with burnout and compared their stigma perceptions with those of the general U.S. population and age-matched individuals. The authors surveyed students at six medical schools in 2012. They measured burnout, symptoms of depression, and quality of life using validated instruments and explored help-seeking behaviors, perceived stigma, personal experiences, and attitudes toward seeking mental health treatment. Of 2,449 invited students, 873 (35.6%) responded. A third of respondents with burnout (154/454; 33.9%) sought help for an emotional/mental health problem in the last 12 months. Respondents with burnout were more likely than those without burnout to agree or strongly agree with 8 of 10 perceived stigma items. Respondents with burnout who sought help in the last 12 months were twice as likely to report having observed supervisors negatively judge students who sought care (odds ratio [OR] 2.06 [95% confidence interval (CI) 1.25-3.39], P student's emotional/mental health problem to others (OR 1.63 [95% CI 1.08-2.47], P = .02). A smaller percentage of respondents would definitely seek professional help for a serious emotional problem (235/872; 26.9%) than of the general population (44.3%) and age-matched individuals (38.8%). Only a third of medical students with burnout seek help. Perceived stigma, negative personal experiences, and the hidden curriculum may contribute.

    Developments and innovation in the areas of mobile information technology, digital media and social networks foster new reflections on computer-mediated communication research, especially in the field of self-presentation. In this context, the selfie as a self-portrait photo is interesting, because as a meaningful gesture, it actively and directly relates the content of the photo to the author of the picture. From the perspective of the selfie as an image and the impression it forms, in the first part of the research we explored the distinctive characteristics of selfie pictures; moreover, from the perspective of the potential reflection of a selfie image on the personality of its author, in the second part we related the characteristics of selfie pictures to various personality constructs (e.g., Big Five personality traits narcissism and femininity-masculinity). Important aspects of selfies especially in relation to gender include the tilt of the head, the side of the face exhibited, mood and head position, later related also to the context of the selfie picture. We found no significant relations between selfie cues and personality constructs. The face-ism index was related to entitlement, and selfie availability to neuroticism. PMID:28197113

    How can the user's access to health information, especially full-text articles, be improved? The solution is building and evaluating the Health SmartLibrary (HSL). The setting is the Galter Health Sciences Library, Feinberg School of Medicine, Northwestern University. The HSL was built on web-based personalization and customization tools: My E-Resources, Stay Current, Quick Search, and File Cabinet. Personalization and customization data were tracked to show user activity with these value-added, online services. Registration data indicated that users were receptive to personalized resource selection and that the automated application of specialty-based, personalized HSLs was more frequently adopted than manual customization by users. Those who did customize customized My E-Resources and Stay Current more often than Quick Search and File Cabinet. Most of those who customized did so only once. Users did not always take advantage of the services designed to aid their library research experiences. When personalization is available at registration, users readily accepted it. Customization tools were used less frequently; however, more research is needed to determine why this was the case.

    Full Text Available Background and aims: Personality psychology research relies on the notion that humans have a single self that is the result of the individual's thoughts, feelings, and behaviors that can be reliably described (i.e., through traits. People who identify themselves as “multiple” have a system of multiple or alternative, selves, that share the same physical body. This is the first study to explore the phenomenon of multiplicity by assessing the experiences of people who identify themselves as “multiple.”Methods: First, an Internet forum search was performed using the terms “multiplicity” and “multiple system.” Based on that search, people who identified themselves as multiple were contacted. Interviews were conducted by a consultant psychiatrist, which produced six case vignettes.Results: Multiplicity is discussed on Twitter, Tumblr, Google+ and several other personal websites, blogs, and forums maintained by multiples. According to the study's estimates, there are 200–300 individuals who participate in these forums and believe they are multiple. Based on the six interviews, it appears that multiples have several selves who are relatively independent of each other and constitute the personality's system. Each “resident person” or self, has their own unique behavioral pattern, which is triggered by different situations. However, multiples are a heterogeneous group in terms of their system organization, memory functions, and control over switching between selves.Conclusions: Multiplicity can be placed along a continuum between identity disturbance and dissociative identity disorder (DID, although most systems function relatively well in everyday life. Further research is needed to explore this phenomenon, especially in terms of the extent to which multiplicity can be regarded as a healthy way of coping.

    The authors examined the extent to which parent involvement in Head Start programs predicted changes in both parent and child outcomes over time, using a nationally representative sample of 1,020 three-year-old children over 3 waves of the Family and Child Experiences Survey. Center policies that promote involvement predicted greater parent involvement, and parents who were more involved in Head Start centers demonstrated increased cognitive stimulation and decreased spanking and controlling behaviors. In turn, these changes in parenting behaviors were associated with gains in children's academic and behavioral skills. These findings suggest that Head Start programs should do even more to facilitate parent involvement because it can serve as an important means for promoting both parent and child outcomes.

    The eye may act as a surrogate for the brain in response to head acceleration during an impact. Passive eye movements in a dynamic system are sensed by microelectromechanical systems (MEMS) inertial measurement units (IMU) in this paper. The technique is validated using a three-dimensional printed scaled human skull model and on human volunteers by performing drop-and-impact experiments with ribbon-style flexible printed circuit board IMUs inserted in the eyes and reference IMUs on the heads. Data are captured by a microcontroller unit and processed using data fusion. Displacements are thus estimated and match the measured parameters. Relative accelerations and displacements of the eye to the head are computed indicating the influence of the concussion causing impacts.

Studies have revealed a need for information and support during the disease process. Likewise, there is support for the positive impacts of physical and social activities for wellbeing in home-dwelling people with dementia. It is important to obtain experiences from next of kin whose spouses or parents participate in such physical and social activities.Aim: The aim of this study was to elucidate the experiences of next of kin to home-dwelling persons in an early stage of dementia who had an opportunity to participate in organized physical and social activities.Method: The study has a qualitative design. Focus group interviews were conducted with ten next of kin to home-dwelling dementia sufferers, who participated in physical and social activities in an activity center. The interview texts were analyzed using qualitative content analysis.Findings: In the analysis, two categories emerged: "a break in the everyday" and "being attended and cared about." Two sub-categories identified in each of the two main categories were: "need of relief" and "meaningful activities;" and "being confirmed" and "sharing experiences and getting advice and help," respectively. These categories were interpreted in an overall theme: "contentment with adapted activities and group meetings provided with a person-centered approach."Conclusion: Adapted physical and social activities led by highly qualified personnel can provide needed relief and support to the next of kin, and

    The goal of this study was to assess how the axis of head rotation, Listing's law, and eye position influence the axis of eye rotation during brief, rapid head rotations. We specifically asked how the axis of eye rotation during the initial angular vestibuloocular reflex (VOR) changed when the pitch orientation of the head relative to Earth-vertical was varied, but the initial position of the eye in the orbit and the orientation of Listing's plane with respect to the head were fixed. We measured three-dimensional eye and head rotation axes in eight normal humans using the search coil technique during head-and-trunk (whole-body) and head-on-trunk (head-only) "impulses" about an Earth-vertical axis. The head was initially oriented at one of five pitch angles (30 degrees nose down, 15 degrees nose down, 0 degrees, 15 degrees nose up, 30 degrees nose up). The fixation target was always aligned with the nasooccipital axis. Whole-body impulses were passive, unpredictable, manual, rotations with peak-amplitude of approximately 20 degrees , peak-velocity of approximately 80 degrees /s, and peak-acceleration of approximately 1000 degrees /s2. Head-only impulses were also passive, unpredictable, manual, rotations with peak-amplitude of approximately 20 degrees , peak-velocity of approximately 150 degrees /s, and peak-acceleration of approximately 3000 degrees /s2. During whole-body impulses, the axis of eye rotation tilted in the same direction, and by an amount proportional (0.51 +/- 0.09), to the starting pitch head orientation (P rotation could be predicted from vectorial summation of the gains (eye velocity/head velocity) obtained for rotations about the pure yaw and roll head axes. Thus, even when the orientation of Listing's plane and eye position in the orbit are fixed, the axis of eye rotation during the VOR reflects a compromise between the requirements of Listing's law and a perfectly compensatory VOR.

  6. Radiation Dose to the Lens of the Eye from Computed Tomography Scans of the Head

    While it is well known that exposure to radiation can result in cataract formation, questions still remain about the presence of a dose threshold in radiation cataractogenesis. Since the exposure history from diagnostic CT exams is well documented in a patient's medical record, the population of patients chronically exposed to radiation from head CT exams may be an interesting area to explore for further research in this area. However, there are some challenges in estimating lens dose from head CT exams. An accurate lens dosimetry model would have to account for differences in imaging protocols, differences in head size, and the use of any dose reduction methods. The overall objective of this dissertation was to develop a comprehensive method to estimate radiation dose to the lens of the eye for patients receiving CT scans of the head. This research is comprised of a physics component, in which a lens dosimetry model was derived for head CT, and a clinical component, which involved the application of that dosimetry model to patient data. The physics component includes experiments related to the physical measurement of the radiation dose to the lens by various types of dosimeters placed within anthropomorphic phantoms. These dosimeters include high-sensitivity MOSFETs, TLDs, and radiochromic film. The six anthropomorphic phantoms used in these experiments range in age from newborn to adult. First, the lens dose from five clinically relevant head CT protocols was measured in the anthropomorphic phantoms with MOSFET dosimeters on two state-of-the-art CT scanners. The volume CT dose index (CTDIvol), which is a standard CT output index, was compared to the measured lens doses. Phantom age-specific CTDIvol-to-lens dose conversion factors were derived using linear regression analysis. Since head size can vary among individuals of the same age, a method was derived to estimate the CTDIvol-to-lens dose conversion factor using the effective head diameter. These conversion

    Although psilocybin has been used for centuries for religious purposes, little is known scientifically about its acute and persisting effects. This double-blind study evaluated the acute and longer-term psychological effects of a high dose of psilocybin relative to a comparison compound administered under comfortable, supportive conditions. The participants were hallucinogen-naïve adults reporting regular participation in religious or spiritual activities. Two or three sessions were conducted at 2-month intervals. Thirty volunteers received orally administered psilocybin (30 mg/70 kg) and methylphenidate hydrochloride (40 mg/70 kg) in counterbalanced order. To obscure the study design, six additional volunteers received methylphenidate in the first two sessions and unblinded psilocybin in a third session. The 8-h sessions were conducted individually. Volunteers were encouraged to close their eyes and direct their attention inward. Study monitors rated volunteers' behavior during sessions. Volunteers completed questionnaires assessing drug effects and mystical experience immediately after and 2 months after sessions. Community observers rated changes in the volunteer's attitudes and behavior. Psilocybin produced a range of acute perceptual changes, subjective experiences, and labile moods including anxiety. Psilocybin also increased measures of mystical experience. At 2 months, the volunteers rated the psilocybin experience as having substantial personal meaning and spiritual significance and attributed to the experience sustained positive changes in attitudes and behavior consistent with changes rated by community observers. When administered under supportive conditions, psilocybin occasioned experiences similar to spontaneously occurring mystical experiences. The ability to occasion such experiences prospectively will allow rigorous scientific investigations of their causes and consequences.

    The aim of this study was to document and compare adverse childhood experiences, and personality profiles in women with borderline personality disorder (BPD) and their sisters, and to determine how these factors impact current psychopathology. Fifty-six patients with BPD and their sisters were compared on measures assessing psychopathology, personality traits, and childhood adversities. Most sisters showed little evidence of psychopathology. Both groups reported dysfunctional parent-child relationships and a high prevalence of childhood trauma. Subjects with BPD reported experiencing more emotional abuse and intrafamilial sexual abuse, but more similarities than differences between probands and sisters were found. In multilevel analyses, personality traits of affective instability and impulsivity predicted DIB-R scores and SCL-90-R scores, above and beyond trauma. There were few relationships between childhood adversities and other measures of psychopathology. Sensitivity to adverse experiences, as reflected in the development of psychopathology, appears to be influenced by personality trait profiles.

    Head and neck cancer patients treated with surgery often experience significant postoperative morbidities. Administering preoperative nutritional intervention may improve surgical outcomes, but there is currently a paucity of data reviewing the association between preoperative nutritional status and postoperative outcome. It is therefore of importance to investigate this association among head and neck cancer patients. To assess the association between preoperative nutritional status and postoperative outcome in head and neck cancer patients treated with surgery, a retrospective study of 70 head and neck cancer patients who were surgically treated between 2013 and 2014 in a tertiary referral head and neck surgery center in Hong Kong was conducted. Clinical data regarding preoperative nutritional status and postoperative outcome were retrieved from a computer record system. Logistic and linear regressions were used to analyze the appropriate parameters. A higher preoperative albumin level was associated with lower rates of postoperative complications and better wound healing (P cancer patients, preoperative intervention strategies that boost albumin levels could be considered for improving surgical outcome.

    Due to high rates of fetal alcohol spectrum disorder (FASD) in South Africa, reducing alcohol use during pregnancy is a pressing public health priority. The aim of this study was to qualitatively explore knowledge and attitudes about maternal alcohol consumption among women who reported alcohol use during pregnancy. The study was conducted in Cape Town, South Africa. Participants were pregnant or within 1 year postpartum and self-reported alcohol use during pregnancy. In-depth interviews explored personal experiences with drinking during pregnancy, community norms and attitudes towards maternal drinking, and knowledge about FASD. Transcripts were analyzed using a content analytic approach, including narrative memos and data display matrices. Interviews revealed competing attitudes. Women received anti-drinking messages from several sources, but these sources were not highly valued and the messages often contradicted social norms. Women were largely unfamiliar with FASD, and their knowledge of impacts of fetal alcohol exposure was often inaccurate. Participants' personal experiences influenced their attitudes about the effects of alcohol during pregnancy, which led to internalization of misinformation. The data revealed a moral conflict that confronted women in this setting, leaving women feeling judged, ambivalent, or defensive about their behaviors, and ultimately creating uncertainty about their alcohol use behaviors. Data revealed the need to deliver accurate information about the harms of fetal alcohol exposure through sources perceived as trusted and reliable. Individual-level interventions to help women reconcile competing attitudes and identify motivations for reducing alcohol use during pregnancy would be beneficial.

    Until the end of the nineties last century personality disorders could not be diagnosed before the age of eighteen. Nevertheless, the results of studies published in the last decade have revealed that personality disorders can be observed in children and adolescents and that personality disorders diagnosed in adult patients had been present as early as in childhood. The knowledge of possible mechanisms shaping personality disorders in childhood is unsatisfactory and needs to be expanded. Developmental psychology explains the development of abnormal personality through inappropriate attachment patterns and abnormal transitions between developmental phases. Genetic and temperamental factors are also important in the aetiology of personality disorders as well as early maladaptive schemas resulting from personal experiences and interactions with others. The aim of this article is to review the current knowledge on the mechanisms shaping the development of personality and personality disorders in childhood and adolescence.

    To illuminate meanings of the lived experiences of dog handlers' when visiting older persons with dementia with their therapy dog. Studies indicate that care of persons with dementia should focus on a person-centred approach with the person's interests in the centre. Animal-assisted therapy using a therapy dog in the care of persons with dementia has been shown to increase well-being and decrease problematic behaviours associated with the illness. A qualitative lifeworld approach was adopted for this study. Data were collected from open-ended interviews with nine dog handlers, and the analysis conducted using the phenomenological hermeneutical method. The structural analysis resulted in one theme, 'Respite from the burden of illness for persons with dementia'. Visiting a person with dementia can be seen as an act of caring, providing temporary respite from their illness, and creating a special relationship between handler and patient. A therapy dog visit can represent a moment of communion between the handler and the person with dementia. Dog handlers use their skills and knowledge to promote a situation that reduces symptoms of illness and encourages healthier behaviour. The results of this study may be of interest to researchers, clinical practitioners, caregivers and dog handlers who care for persons with dementia using therapy dog teams on prescription as an alternative method to minimise behavioural and psychological symptoms of dementia. © 2016 John Wiley & Sons Ltd.

    There are few studies of young persons (old) with dementia, and the situation of their children has been a neglected research field. The aim is explore how adult children of a parent with young-onset dementia have experienced the development of their parents' dementia and what needs they have for assistance. Qualitative interviews with 14 informants (aged 20-37 years; 12 daughters, 2 sons) during 2011 were conducted and analyzed thematically. The informants experienced great burdens and felt neglected during the development of their parents' dementia, both by their family and by health and social services. They emphasized a need to be seen as individuals, with their experiences, feelings, and personal needs for assistance. The stresses experienced during the development of parental dementia seemed to increase conflicts in the family. There were variations in reactions between children, depending on age, gender, family structure and relationships, responsibilities, personal relations with both parents, and whether there was an adult primary caregiver. The length of time living together with the parent with dementia seemed to increase the stress and burden to the children. They expressed a great need for information and support. The findings strengthen the notion of the need for family-oriented support, combined with person-centered care for the children according to their needs. In addition, group meetings and contact with other young people in the same stage of life could be of interest for some.

    Electroconvulsive therapy (ECT) is generally contraindicated in patients with intracranial mass lesions or in the presence of increased intracranial pressure. The purpose of this study was to determine the prevalence of incidental abnormalities on routine cross-sectional head imaging, including CT and MRI, that would preclude subsequent ECT. This retrospective study involved a review of the electronic medical records of 105 patients (totaling 108 imaging studies) between April 27, 2007, and March 20, 2015, referred for cranial CT or MRI with the primary indication of pre-ECT evaluation. The probability of occurrence of imaging findings that would preclude ECT was computed. A cost analysis was also performed on the practice of routine pre-ECT imaging. Of the 105 patients who presented with the primary indication of ECT clearance (totaling 108 scans), 1 scan (0.93%) revealed findings that precluded ECT. None of the studies demonstrated findings that indicated increased intracranial pressure. A cost analysis revealed that at least $18,662.70 and 521.97 relative value units must be expended to identify one patient with intracranial pathology precluding ECT. The findings of this study demonstrate an extremely low prevalence of findings that preclude ECT on routine cross-sectional head imaging. The costs incurred in identifying a potential contraindication are high. The authors suggest that the performance of pre-ECT neuroimaging be driven by the clinical examination.

    To describe transsexual persons' experiences of encounters with healthcare professionals during the sex reassignment process. Transsexual persons are individuals who use varying means to alter their natal sex via hormones and/or surgery. Transsexual persons may experience stigma, which increases the risk of psychological distress. Mistreatments by healthcare professionals are common. Qualitative studies addressing transsexual persons' experiences of healthcare are scarce. Qualitative descriptive design. A Swedish non-clinical convenience sample was used, consisting of six persons who had been diagnosed as transsexual, gone through sex reassignment surgery or were at the time of the interview awaiting surgery. Semi-structured interviews were undertaken, and data were analysed using manifest qualitative content analysis. Three categories and 15 subcategories were identified. The encounters were perceived as good when healthcare professionals showed respect and preserved the transsexual person's integrity, acted in a professional manner and were responsive and built trust and confidence. However, the participants experienced that healthcare professionals varied in their level of knowledge, exploited their position of power, withheld information, expressed gender stereotypical attitudes and often used the wrong name. They felt vulnerable by having a condescending view of themselves, and they could not choose not to be transsexual. They felt dependent on healthcare professionals, and that the external demands were high. Transsexual persons are in a vulnerable position during the sex reassignment surgery process. The encounters in healthcare could be negatively affected if healthcare professionals show inadequate knowledge, exploit their position of power or express gender stereotypical attitudes. A good encounter is characterised by preserved integrity, respect, responsiveness and trust. Improved education on transgender issues in nursing and medical education is

    The cancer risk estimation constitutes one way for the evaluation of the public health, regarding computed tomography (CT) exposures. Starting from the hypothesis that the optimization of CT protocols would reduce significantly the added cancer risk, the purpose of this research was the application of optimization strategies regarding head CT protocols, in order to reduce the factors affecting the risk of induced cancer. The applied systemic approach included technological and human components, represented by quantitative physical factors. the volumetric kerma indexes, compared with respect to standard, optimized and reference values, were evaluated with multiple means comparison method. The added cancer risk resulted from the application of the methodology for biological effects evaluation, at low doses with low Linear Energy Transfer. Human observers in all scenarios evaluated the image quality. the reduced dose was significantly lower than for standard head protocols and reference levels, where: (1) for pediatric patients, by using an Automatic Exposure Control system, a reduction of 31% compared with standard protocol and ages range of 10-14, and (2) adults, using a Bilateral Filter for images obtained at low doses of 62% from those of standard head protocol. The risk reduction was higher than 25%. The systemic approach used allows the effective identification of factors involved on cancer risk related with exposures to CT. The combination of dose modulation and image restoration with Bilateral Filter, provide a significantly reduction of cancer risk, with acceptable diagnostic image quality. (Author)

    Socioeconomic factors and previous experiences of delivery are known to influence pregnant women's fear of childbirth. The aim of this study was to investigate the associations between stable personality traits, fear of childbirth during late pregnancy, and experience of the delivery. Self-report questionnaires were completed twice, during gestation week 34-37, and at 1-week postpartum. Comparisons were made between 85 women who had sought help from a fear-of-childbirth team, and a group (n=177) from routine antenatal care. Correlations between fear of childbirth, personality variables and experience of childbirth were calculated. The women who had sought help tended to be more anxiety-prone, more short-tempered, and lower in socialisation, although within the normal range. In spite of counselling, they reported more intense fear of delivery and fear of pain compared with the comparison group. Women with intense fear of childbirth, who were low in socialisation and high in psychasthenia, had a more negative experience of their current childbirth. Women with intense fear of childbirth differ from other pregnant women also in personality. Methods for treating fear of childbirth should be further developed in order to diminish the risk of a negative birth experience.

    This paper examines narrative methodologies as one approach to exploring issues of gender, education and social justice and, particularly, insights into "undoing gender". It furthermore examines the possibilities of exploring gender and its multiple intersections in a range of global and policy contexts through the use of personal experience approaches. The "storying" of lived experience is examined as a means of challenging dominant discourses which can construct and other individuals and groups in relation to many aspects of gender and education. Drawing on intersectionality, as a complex and developing feminist theory, the paper considers ways in which narrative can illuminate often hidden complexities while seeking to avoid generalisations and essentialisms. The difficulties of using narrative in relation to these aims are explored in the light of the warnings of feminist writers such as Michele Fine and bell hooks. The paper briefly considers narrative as both methodology and phenomenon, and finally, drawing on critical discourse analysis, discusses the potential of intersectionality and narrative in relation to undoing gender.

    PURPOSE The explosion of evidence in the last decade supporting the role of spirituality in whole-person patient care has prompted proposals for a move to a biopsychosocial-spiritual model for health. Making this paradigm shift in today’s multicultural societies poses many challenges, however. This article presents 2 theoretical models that provide common ground for further exploration of the role of spirituality in medicine. METHODS The 3 H model (head, heart, hands) and the BMSEST models (body, mind, spirit, environment, social, transcendent) evolved from the author’s 12-year experience with curricula development regarding spirituality and medicine, 16-year experience as an attending family physician and educator, lived experience with both Hinduism and Christianity since childhood, and a lifetime study of the world’s great spiritual traditions. The models were developed, tested with learners, and refined. RESULTS The 3 H model offers a multidimensional definition of spirituality, applicable across cultures and belief systems, that provides opportunities for a common vocabulary for spirituality. Therapeutic options, from general spiritual care (compassion, presence, and the healing relationship), to specialized spiritual care (eg, by clinical chaplains), to spiritual self-care are discussed. The BMSEST model provides a conceptual framework for the role of spirituality in the larger health care context, useful for patient care, education, and research. Interactions among the 6 BMSEST components, with references to ongoing research, are proposed. CONCLUSIONS Including spirituality in whole-person care is a way of furthering our understanding of the complexities of human health and well-being. The 3 H and BMSEST models suggest a multidimensional and multidisciplinary approach based on universal concepts and a foundation in both the art and science of medicine. PMID:18779550
