  2. Dimensions of psychological stress in peacekeeping operations. (United States)

    Bartone, P T; Adler, A B; Vaitkus, M A


    U.S. military forces are increasingly involved in a variety of multinational peacekeeping and humanitarian assistance missions. How well combat-trained units and soldiers adapt to these new roles will determine U.S. success in such operations, as well as the future health and readiness of the force. In preparing soldiers for such missions, it is critical that leaders and health care providers have a clear understanding of the nature of the stressors they are likely to encounter. This report summarizes findings from a longitudinal, descriptive case study of a U.S. Army medical unit performing a peacekeeping mission in the former Yugoslavia. The goal of the investigation was to identify key sources of stress and to delineate the effect of these stressors on the health, morale, and mental readiness of soldiers. Findings suggest a range of psychological stressors that varies somewhat across operational phases of a peacekeeping mission. Furthermore, the degree of stress experienced in various areas correlates significantly with depression, psychiatric symptoms, and low reported morale. The range of stressors is reduced and summarized in a conceptually derived model of five underlying dimensions of psychological stress salient to soldier adaptation in peacekeeping operations: isolation, ambiguity, powerlessness, boredom, and danger/threat. This model provides a useful heuristic for organizing thinking about stress in peacekeeping operations and leads to several recommendations for "countermeasures" that organizational leaders can take to maintain soldier psychological readiness during peacekeeping operations.

    Full Text Available Peacekeeping operations are but one aspect of the systems of peace that have evolved over the past seven decades in a world that is riven with violence of all kinds. With the end of cold war in the late eighties of the last century we have come to see much intrastate violence, in addition to usual interstate hostilities and war, arising out of religious, political, ethnic and economic differences between people. In the changed scenario peacekeeping operations have become complex politico-military-humanitarian efforts. A soldier, trained for conventional military operations, is obliged to participate in the unconventional operations of waging peace in alien lands often in volatile and violent situations and in the process he stands to get exposed to widely variable demands for adjustment that have the potential to bring to the fore many maladaptive responses.

  14. The Association of Psychological Empowerment and Job Burnout in Operational Staff of Tehran Emergency Center. (United States)

    Ghaniyoun, Aram; Shakeri, Khosro; Heidari, Mohammad


    Workers in social service professions are the first candidates for job burnout. The researchers believe this is due to daily exposure to stressful situations and lack of positive conditions in the workplace. It seems that psychological empowerment of staff can affect their job burnout. This study aimed to investigate the relationship between psychological empowerment and job burnout in operational staff of emergency center. This was a descriptive correlational study. A total of 1100 operational staff of emergency center were evaluated, and of which, 285 persons were selected by simple random sampling method. Data were collected using Spritzer's psychological empowerment and Maslach Burnout Inventory questionnaires. SPSS software, version 18, was used for data analysis along with descriptive analytical tests. The findings of this study revealed that the majority of units (46%) were in intermediate level in terms of empowerment. Similarly, the majority of cases had intermediate level (77.5%), and a minor percentage (8.4%) had low levels of job burnout. Based on Pearson's correlation test, there was a significant invert correlation between psychological empowerment and job burnout. This inverse and significant relationship was also observed between the four components of psychological empowerment (competence, self-determination, impact, and meaning) and job burnout. According to the results of the study, policy makers and health planners can take some measures in enhancing psychological empowerment to prevent problems associated with job burnout, by identifying stressors and strategies to deal with them.

  15. Simulating environmental and psychological acoustic factors of the operating room. (United States)

    Bennett, Christopher L; Dudaryk, Roman; Ayers, Andrew L; McNeer, Richard R


    In this study, an operating room simulation environment was adapted to include quadraphonic speakers, which were used to recreate a composed clinical soundscape. To assess validity of the composed soundscape, several acoustic parameters of this simulated environment were acquired in the presence of alarms only, background noise only, or both. These parameters were also measured for comparison from size-matched operating rooms at Jackson Memorial Hospital. The parameters examined included sound level, reverberation time, and predictive metrics of speech intelligibility in quiet and noise. It was found that the sound levels and acoustic parameters were comparable between the simulated environment and the actual operating rooms. The impact of the background noise on the perception of medical alarms was then examined, and was found to have little impact on the audibility of the alarms. This study is a first in kind report of a comparison between the environmental and psychological acoustical parameters of a hospital simulation environment and actual operating rooms.

  18. Effects of Pre-operative Psychological Status on Post-operative Recovery: A Prospective Study. (United States)

    Aspari, Ajay Raghunath; Lakshman, K


    Often in clinical practice, a spectrum of outcomes from surgery may be observed ranging from a quick and comfortable recovery to a recovery punctuated by persistent pain and decreased quality of life. While there has been a fast pace of advances made in the field of operative surgery, surgeons seldom pay attention to factors such as the psychological profile of a patient that can affect recovery from surgery. To study the effects of pre-operative psychological profile on post-operative recovery in terms of pain, return to work and quality of life. Consecutive patients undergoing laparoscopic surgeries at Sagar Hospitals, Jayanagar, were recruited. All patients were assessed for psychological status using the screening for illness behaviour questionnaire (SIBQ) and pain catastrophizing scale (PCS). Following surgery, they were followed up for a period of 3 months-on post-operative day 1, post-operative day 7, 1 month and 3 months from the date of surgery. Post-operative pain was measured using the visual analogue scale (Wong-Baker's), return to work was documented in days and quality of life was measured using the Short Form-36 version 2 (SF-36v2) Health Survey. The Pearson's correlation coefficients were used to compare variables with continuous data and Chi-square and Fisher's tests were used to test categorical data for significance. In a total of 98 patients recruited, 50 patients had a complete follow-up of 3 months. Significant correlations existed between the pre-operative markers and markers of recovery. The Chi-square test and Fisher's exact tests showed significant differences in the scores of pre-operative markers between the groups of patients who developed chronic pain and those who did not. Difference in scores with regard to quality of life was also noted. Psychological status does play a role in post-operative recovery. This result opens up scope for counselling patients towards a healthy and comfortable recovery from surgery.

    Beven, G.; Vander Ark, S. T.; Holland, A. W.


    Since NASA began human presence on the International Space Station (ISS) in November 1998, crews have spent two to seven months onboard. In March 2015 NASA and Russia embarked on a new era of ISS utilization, with two of their crewmembers conducting a one-year mission onboard ISS. The mission has been useful for both research and mission operations to better understand the human, technological, mission management and staffing challenges that may be faced on missions beyond Low Earth Orbit. The work completed during the first 42 ISS missions provided the basis for the pre-flight, in-flight and post-flight work completed by NASA's Space Medicine Operations Division, while our Russian colleagues provided valuable insights from their long-duration mission experiences with missions lasting 10-14 months, which predated the ISS era. Space Medicine's Behavioral Health and Performance Group (BHP) provided pre-flight training, evaluation, and preparation as well as in-flight psychological support for the NASA crewmember. While the BHP team collaboratively planned for this mission with the help of all ISS international partners within the Human Behavior and Performance Working Group to leverage their collective expertise, the US and Russian BHP personnel were responsible for their respective crewmembers. The presentation will summarize the lessons and experience gained within the areas identified by this Working Group as being of primary importance for a one-year mission.

  1. A psychological profile of a serial killer: a case report. (United States)

    Dogra, T D; Leenaars, Antoon A; Chadha, R K; Manju, Mehta; Lalwani, Sanjeev; Sood, Mamta; Lester, David; Raina, Anupuma; Behera, C


    Serial killers have always fascinated society. A serial killer is typically defined as a perpetrator who murders three or more people over a period of time. Most reported cases of serial killers come from the United States and Canada. In India, there are few reported cases. We present, to the best of our knowledge, the first Indian case in the literature. The present case is of a 28-year-old man, Surinder Koli. The Department of Forensic Medicine & Toxicology, All India Institute of Medical Sciences, New Delphi handled the forensic study. We present a most unique psychological investigation into the mind of a serial killer.

  2. Prediction of persistent post-operative pain: Pain-specific psychological variables compared with acute post-operative pain and general psychological variables. (United States)

    Horn-Hofmann, C; Scheel, J; Dimova, V; Parthum, A; Carbon, R; Griessinger, N; Sittl, R; Lautenbacher, S


    Psychological variables and acute post-operative pain are of proven relevance for the prediction of persistent post-operative pain. We aimed at investigating whether pain-specific psychological variables like pain catastrophizing add to the predictive power of acute pain and more general psychological variables like depression. In all, 104 young male patients undergoing thoracic surgery for pectus excavatum correction were studied on the pre-operative day (T0) and 1 week (T1) and 3 months (T2) after surgery. They provided self-report ratings (pain-related: Pain Catastrophizing Scale, Pain Anxiety Symptoms Scale = PASS, Pain Vigilance and Awareness Questionnaire = PVAQ; general psychological: Screening for Somatoform Symptoms, State-Anxiety Inventory-X1, Center for Epidemiologic Studies Depression Scale = CES-D). Additional predictors (T1) as well as criterion variables (T2) were pain intensity (Numerical Rating Scale) and pain disability (Pain Disability Index). Three months after surgery, 25% of the patients still reported clinically relevant pain (pain intensity ≥3) and over 50% still reported pain-related disability. Acute post-operative pain as well as general psychological variables did not allow for a significant prediction of persistent post-operative pain; in contrast, pain-related psychological variables did. The best single predictors were PASS for pain intensity and PVAQ for pain disability. Pain-related psychological variables derived from the fear-avoidance model contributed significantly to the prediction of persistent post-operative pain. The best possible compilation of these measures requires further research. More general psychological variables may become relevant predictors later in the medical history. Our results suggest that pain-specific psychological variables such as pain anxiety and pain hypervigilance add significantly to the prediction of persistent post-operative pain and might even outperform established predictors such as

    Job burnout is a major concern within the service industry. However, there is a lack of research exploring positive resources for combating burnout among telephone operators. The purpose of this study was to examine the associations between resilience, psychological empowerment, and job burnout, and the mediating role of psychological empowerment. A cross-sectional survey of 575 telephone operators was conducted in 2 call centers in Shandong Province, China. Self-report questionnaires were used to assess job burnout symptoms, resilience, and psychological empowerment. Hierarchical linear regression was performed to analyze the degree to which resilience and psychological empowerment are associated with job burnout, and the mediating role of psychological empowerment. The results showed that resilience and psychological empowerment had significant "net effects" on job burnout, which may represent positive resources for combating job burnout. Psychological empowerment may partially mediate the relationship between resilience and job burnout. Thus, interventions focused on resilience and psychological empowerment may be useful options for managers concerned about burnout. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Japanese surveys and experiments have found that operators sometimes find it difficult to anticipate automatic processes, which in turn limits their ability to keep up with those processes. One of the factors which makes anticipation difficult is the lack of flexible communication between operators and computers - communication which is easier among human operators. At present the only way of dealing with this psychological effect is to ensure that trainees fully master the characteristics of the automated processes. (author).

    Full Text Available The Parent Child Psychological Support Program (PCPS was established in an area of South West Dublin in 2001. Since then until May 2008 it has offered its services to over 700 children and their parents. This preventative, parenting support service is available to all parents of children aged 3 to 18 months within its catchment area. During periodical visits, the infant’s development and growth are measured and parents receive specific information about their child’s progress. Parents are empowered in their parenting practices, thus promoting consistency and synchrony in parent-child interaction. Between 2001 and 2006, 538 parents and their infants participated in the Program. Out of these cases, 130 (24.16% were considered to require additional support and were included in the Monthly Meeting Case Review (MM based on initial concerns The aims of this study were: 1. to review the first five years of MM cases and to explore the socio-demographic profile of the MM cases in comparison to those not in need of additional support (non-MM and 2. To illustrate an approach to refining the case review process which will inform practice and provides the service providers with better understanding of the early detection of parent-child relation difficulties. In pursuing this goal the cases screened over five years of practice were analyzed to explore the structure of the different factors by using statistical techniques of data reduction, i.e. factor analysis. The results showed that the MM group differed on several socio-demographic dimensions from the non-MM group and there was a four factor structure underlying the case review decision process. Implications of this research are discussed.

  9. Psychological Features of Takotsubo Cardiomyopathy: Report of Four Cases

    Directory of Open Access Journals (Sweden)

    Yaser Jenab


    Full Text Available Takotsubo or stress-induced cardiomyopathy is a cardiomyopathy in which the patient has a sudden onset, reversible left ventricular systolic dysfunction without any significant coronary artery disease. Four women, who were at a mean age of 64 years and suffered from chest pain exacerbated by emotional stress, were admitted as cases of acute coronary syndrome and were completely evaluated through precise history taking, physical examination, and ECG. Coronary angiography or coronary multidetector computed tomography was used to exclude significant coronary artery disease. In these patients with confirmed Takotsubo cardiomyopathy, in addition to the Diagnostic and Statistical Manual of the American Psychiatric Association (DSM-IV criteria, a 71-item form of the Minnesota Multiphasic Personality Inventory (MMPI-Mini-Mult-was employed for psychological assessment. The main common elevated scale was hypochondriasis. Individuals with high scores on this scale are obsessed with themselves, especially in regard to their body, and often use their disease symptoms in order to manipulate others. They are mainly passive aggressive, critical, and demanding, which stems from their lack of effective verbal abilities as a means of communication, specifically when it comes to anger or hostility expression. To the best of our knowledge, there is no available study evaluating patients with Takotsubo cardiomyopathy using the Mini-Mult questionnaire for psychological assessment.

    Full Text Available Aim: to conduct a comparative analysis of the psychological characteristics of the most and least successful main control room operators. Material and Methods. Two NPP staff groups: the most and least successful main control room operators, who worked in routine operating conditions, were surveyed. Expert evaluation method has been applied to identify the groups. The subjects were administered the Minnesota Multiphasic Personality Inventory (MMPI, Cattell's Sixteen Personality Factor Questionnaire (16PF form A and Raven's Progressive Matrices test. Results. Numerous significant psychological differences between the groups of most and least successful control room operators were obtained: the best operators were significantly more introverted and correctly solved more logical tasks with smaller percentage of mistakes under time pressure than worst ones. Conclusions: 1. The psychodiagnostic methods used in the study were adequate to meet research objective 2. Tendency to introversion, as well as developed the ability to solve logic problems undertime pressure, apparently, are important professional qualities for control room operators. These indicators should be considered in the process of psychological selection and professional guidance of nuclear power plant operators.

  12. Does pre-operative psychological distress affect patient satisfaction after primary total hip arthroplasty?

    Directory of Open Access Journals (Sweden)

    Nolan John


    Full Text Available Abstract Background There are concerns that pre-operative psychological distress might be associated with reduced patient satisfaction after total hip replacement (THR. Methods We investigated this in a multi-centre prospective study between January 1999 and January 2002. We dichotomised the patients into the mentally distressed (MHS ≤ 56 and the not mentally distressed (MHS > 56 groups based on their pre-operative Mental Health Score (MHS of SF36. Results 448 patients (340 not distressed and 108 distressed completed the patient satisfaction survey. Patient satisfaction rate at five year was 96.66% (415/448. There was no difference in patient satisfaction or willingness to have the surgery between the two groups. None of pre-operative variables predicted five year patient satisfaction in logistic regression. Conclusions Patient satisfaction after surgery may not be adversely affected by pre-operative psychological distress.

  13. Psychological attributes of South African Navy Underwater Sabotage Device Disposal operators. (United States)

    van Wijk, C; Waters, A H


    The first of two studies described here aimed to determine the extent to which psychological instruments could be used to describe the psychological profile of Underwater Sabotage Device Disposal (USDD) operators in the South African Navy. The Advanced Progressive Matrices, 16-Personality Factor Questionnaire (16PF), Self-Directed Search Questionnaire, and Rey Complex Figure Test were used. In this study, five 16PF factors appeared to be most descriptive of the sample. They were adventurous, assertive, self-assured, emotionally stable, and tough minded. These factors appeared appropriate when discussed from an environmental demand perspective. Occupational interests were realistic and social, and operators scored high on the Complex Figure Test. The second study aimed to determine the extent to which the 16PF could differentiate between USDD operators and other clearance divers. Two factors showed a significant difference between the two groups. The USDD operators were more adventurous and more assertive, which also appeared appropriate when discussed from an environmental demand perspective.

    Sánchez-Reales, S; Tornero-Gómez, M J; Martín-Oviedo, P; Redondo-Jiménez, M; del-Arco-Jódar, R


    Our aim is to present the first year of operation of a Clinical Psychology service in a Primary Care setting. A descriptive study was performed by analysing the requests and the care intervention of the Psychology Service, in collaboration with 36 general practitioners (33% of the staff), belonging to 6 health centres. Within the one year period, 171 outpatients from 15 years and older were referred with mild psychological disorders (> 61 in the global assessment functioning scale, APA, 2002). A total of 111 outpatients received psychological care. The main diagnoses were adaptation disorder, affective disorder, and anxiety. More than half (54.82%) of them achieved a full recovery. After a year follow up, a drop of 25.19% was observed in medicines use. The Primary Care Psychology team is a halfway unit between Primary Care practitioners and specialised units in order to deal with mild mental symptomatology which otherwise could be undertreated. It represents an important support for practitioners. Secondly, the early intervention can prevent mental problems becoming chronic, as shown by the drop in medication use. In spite of the not very high agreement between the practitioner's diagnoses and those made by the Psychology unit, it has set up an important means of communication and with direct and immediate interdisciplinary action. This should eventually lead to savings in economic resources and human suffering. Copyright © 2014. Publicado por Elsevier España, S.L.U.

  16. Exploring the psychological health of emergency dispatch centre operatives: a systematic review and narrative synthesis

    Directory of Open Access Journals (Sweden)

    Sarah E. Golding


    Full Text Available Background The study objective was to investigate and synthesize available evidence relating to the psychological health of Emergency Dispatch Centre (EDC operatives, and to identify key stressors experienced by EDC operatives. Methods Eight electronic databases (Embase, PubMed, Medline, CINAHL, PsycInfo, PsycArticles, The Psychology and Behavioural Sciences Collection, and Google Scholar were searched. All study designs were included, and no date limits were set. Studies were included if they were published in English, and explored the psychological health of any EDC operatives, across fire, police, and emergency medical services. Studies were excluded if they related solely to other emergency workers, such as police officers or paramedics. Methodological quality of included studies was assessed using checklists adapted from the Critical Appraisal Skills Programme. A narrative synthesis was conducted, using thematic analysis. Results A total of 16 articles were included in the review. Two overarching themes were identified during the narrative synthesis: ‘Organisational and Operational Factors’ and ‘Interactions with Others’. Stressors identified included being exposed to traumatic calls, lacking control over high workload, and working in under-resourced and pressured environments. Lack of support from management and providing an emotionally demanding service were additional sources of stress. Peer support and social support from friends and family were helpful in managing work-related stress. Discussion EDC operatives experience stress as a result of their work, which appears to be related to negative psychological health outcomes. Future research should explore the long-term effects of this stress, and the potential for workplace interventions to alleviate the negative impacts on psychological health.

  17. Divorce and Death: A Case Study for Health Psychology (United States)

    Sbarra, David A.; Hasselmo, Karen; Nojopranoto, Widyasita


    Marital separation and divorce are associated with increased risk for early death, and the magnitude of this association rivals that of many well-established public health factors. In the case of divorce, however, the mechanisms explaining precisely why and how some people are at risk for early death remain unclear. This paper reviews what is known about the association between divorce and risk for all-cause mortality, then discusses four emerging themes in this area of research: the biological intermediaries linking divorce to pathophysiology and disease onset, moving beyond the statistical mean, focusing research on the diathesis-stress model, and studying how opportunity foreclosures may place people on a trajectory toward poor distal health outcomes. These ideas are grounded in a set of public lay commentaries about the association between divorce and death; in this way, the paper seeks to integrate current research ideas with how the general public thinks about divorce and its correlates. Although this paper focuses on divorce, many of the emerging themes are applicable to the study of psychosocial stress and health more generally. Therefore, the study of divorce and death provides a good case study for health psychology and considers new questions that can be pursued in a variety of research areas. PMID:23284588

    Chikuhwa, Eleonora


    Research on psychological abuse is still in the early stages; the nature of it renders it difficult to define, and even at times to detect. This thesis examines psychological abuse in a Namibian context using in-depth interviews with six women who experienced domestic violence. The aim was to examine the women‟s perceptions of psychological abuse and the response received from various networks of support. Additionally, I investigated whether Western theories of domestic violence could be usef...

  20. Expectation Violation in Political Decision Making: A Psychological Case Study

    Directory of Open Access Journals (Sweden)

    Michael Öllinger


    Full Text Available Since the early Gestaltists there has been a strong interest in the question of how problem solvers get stuck in a mental impasse. A key idea is that the repeated activation of a successful strategy from the past results in a mental set (‘Einstellung’ which determines and constrains the option space to solve a problem. We propose that this phenomenon, which mostly was tested by fairly restricted experiments in the lab, could also be applied to more complex problem constellations and naturalistic decision making. We aim at scrutinizing and reconstructing how a mental set determines the misinterpretation of facts in the field of political decision making and leads in consequence to wrong expectations and an ill-defined problem representation. We will exemplify this psychological mechanism considering a historical example, namely the unexpected stabilization of the Franco regime at the end of World War II and its survival thereafter. A specific focus will be drawn to the significant observation that erroneous expectations were taken as the basis for decisions. This is congruent with the notion that in case of discrepancy between preconceived notions and new information, the former prevails over the new findings. Based on these findings, we suggest a theoretical model for expectation violation in political decision making and develop novel approaches for cognitive empirical research on the mechanisms of expectation violation and its maintenance in political decision making processes.

    Since the early Gestaltists there has been a strong interest in the question of how problem solvers get stuck in a mental impasse. A key idea is that the repeated activation of a successful strategy from the past results in a mental set ('Einstellung') which determines and constrains the option space to solve a problem. We propose that this phenomenon, which mostly was tested by fairly restricted experiments in the lab, could also be applied to more complex problem constellations and naturalistic decision making. We aim at scrutinizing and reconstructing how a mental set determines the misinterpretation of facts in the field of political decision making and leads in consequence to wrong expectations and an ill-defined problem representation.

  2. Comments on the 1950s applications and extensions of Skinner's operant psychology


    Morris, Edward K.


    These comments address Laties', Dewsbury's, and Rutherford's papers on the extension and application of Skinner's operant psychology during the 1950s. I begin by reflecting on the papers' overall theme—that the success of behavior analysis lies in its practical applications—and add some comments on Planck's principle. I then turn to the three papers and address such topics as (a) other applications and extensions (e.g., the U.S. space program), (b) relations between the research and researche...

  6. Psychosocial Work Factors, Blood Pressure and Psychological Strain in Male Bus Operators (United States)

    CENDALES, Boris; USECHE, Sergio; GÓMEZ, Viviola


    The research aim was to predict the bus operators’ blood pressure (BP) and psychological strain using a combination of the Job-Demand Control (JDC) and Effort-Reward Imbalance (ERI) models. The study was conducted with a sample of 139 bus operators in the city of Bogotá (Colombia), who answered a questionnaire that included the Job Content Questionnaire (JCQ), the ERI Questionnaire, and the General Health Questionnaire (GHQ). Four consecutive BP readings taken in the workplace were averaged to calculate an estimation of the bus operators’ BP. By conducting multiple linear regressions it was found that, taken together, JDC and ERI models explain 10% (F(11,139)=2,502; p=0.00) of systolic BP variance, and 34% (F(6,139)=8,638; p=0.00) of psychological strain variance. These results suggest that the JDC and ERI predictors provide complementary information which increases the probability of accurately model the bus operators’ health. PMID:24869893

  7. Sociopolitical diversity in psychology. The case for pluralism. (United States)

    Redding, R E


    Psychology celebrates diversity, recognizes the value and legitimacy of diverse beliefs, and strives to be inclusive. Yet, the profession lacks sociopolitical diversity. Most psychologists are politically liberal, and conservatives are vastly underrepresented in the profession. Moreover, when sociopolitical views guide the research, advocacy, or professional practice of psychologists, those views most often are liberal. The lack of political diversity in psychology has unintended negative consequences for research, policy advocacy, clinical practice, the design and implementation of social interventions, and professional education. It excludes or marginalizes conservatives and conservative views, having detrimental effects on the profession in each of these areas. This article examines the importance of political diversity and the negative consequences of its absence and provides strategies for increasing sociopolitical pluralism in psychology.

  10. Human Behavior and Performance Support for ISS Operations and Astronaut Selections: NASA Operational Psychology for Six-Crew Operations (United States)

    VanderArk, Steve; Sipes, Walter; Holland, Albert; Cockrell, Gabrielle


    The Behavioral Health and Performance group at NASA Johnson Space Center provides psychological support services and behavioral health monitoring for ISS astronauts and their families. The ISS began as an austere outpost with minimal comforts of home and minimal communication capabilities with family, friends, and colleagues outside of the Mission Control Center. Since 1998, the work of international partners involved in the Space Flight Human Behavior and Performance Working Group has prepared high-level requirements for behavioral monitoring and support. The "buffet" of services from which crewmembers can choose has increased substantially. Through the process of development, implementation, reviewing effectiveness and modifying as needed, the NASA and Wyle team have proven successful in managing the psychological health and well being of the crews and families with which they work. Increasing the crew size from three to six brought additional challenges. For the first time, all partners had to collaborate at the planning and implementation level, and the U.S. served as mentor to extrapolate their experiences to the others. Parity in available resources, upmass, and stowage had to be worked out. Steady progress was made in improving off-hours living and making provisions for new technologies within a system that has difficulty moving quickly on certifications. In some respect, the BHP support team fell victim to its previous successes. With increasing numbers of crewmembers in training, requests to engage our services spiraled upward. With finite people and funds, a cap had to placed on many services to ensure that parity could be maintained. The evolution of NASA BHP services as the ISS progressed from three- to six-crew composition will be reviewed, and future challenges that may be encountered as the ISS matures in its assembly-complete state will be discussed.

  11. Questions of legal awareness in psychology of citizens' assistance to bodies exercising operative investigation

    Directory of Open Access Journals (Sweden)

    Kalyagin Y.S.


    Full Text Available This article attempts to address the issues of legal awareness formation in the context of the citizens' assistance to the bodies, engaged in the operative investigation. We revealed legal content and basis citizens' assistance to the bodies doing operative investigation. From the moral and ethical point of view, we analyze the main motives of this assistance. We show the historical background of the Russian justice features in this context. We performed a comparative analysis of the attitude of citizens to the institution of assistance in Russia and some other countries. We considered individual sense of justice from the perspective of legal psychology, showed the main points of view on justice as a psychological study subject. We analyzed existing psychodiagnostic tools, aimed at determining the level of justice, estimated and identified the areas for further research. We show the reserve in the fight against crime in the form of increased legal awareness of citizens and law enforcement personnel, engaged in the operative activity.

  12. ESID, dissemination, and community psychology: a case of partial implementation? (United States)

    Gray, Denis O; Jakes, Susan S; Emshoff, James; Blakely, Craig


    Dissemination, the second stage of Experimental Social Innovation and Dissemination (ESID) is a critical, if not defining, element of this social change model. This paper attempts to assess the extent to which community psychology has adopted and implemented ESID's dissemination focus in its training and publications. We identify four levels of commitment to dissemination: dissemination advocate, dissemination activist, dissemination researcher, and experimental dissemination researcher. Content analyses of textbooks, journal publications, and conference papers and a brief survey of doctoral training in the field were conducted. Findings suggest that the dissemination aspects of ESID have been modestly and partially implemented within the field. That is, although there is some evidence of a commitment to dissemination practice (advocate, activist), there is much less evidence of a commitment to dissemination research. The implications of these findings for the effectiveness of the ESID model and for training and practice in community psychology are discussed.

  13. Psychological differences between patients that elect operative or nonoperative treatment for trapeziometacarpal joint arthrosis. (United States)

    Lozano-Calderon, Santiago A; Souer, J Sebastiaan; Jupiter, Jesse B; Ring, David


    Among 44 consecutive patients electing operative treatment of trapeziometacarpal arthrosis, three age- and gender-matched controls that presented during the same time period but had not yet requested operative treatment were selected from billing records. Each patient and control was mailed a survey that included an upper extremity-specific health status measure (Disabilities of the Arm, Shoulder, and Hand questionnaire; DASH) and a set of questionnaires evaluating psychological factors including the Pain Anxiety Symptoms Scale (PASS), the Pain Catastrophizing Scale (PCS) and the Center for the Epidemiological Study of Depression (CES-D) instrument. Seventy-two patients (45%; 31 that elected operative and 41 nonoperative care) returned a completed questionnaire with usable data. Older age was the only significant predictor of choice for nonoperative treatment among survey responders. Arm-specific disability (DASH) correlated with the CES-D, PASS, and PCS scores, and the influence of radiographic severity was near significant (p = 0.06). Stepwise multiple linear regression resulted in a model including the CES-D and PCS scores and accounting for 51% of the variability in DASH scores for patients from both cohorts. For both the operative and nonoperative cohorts, a model including CES-D alone accounted for 50% of the variability in DASH scores (p election of operative treatment in patients with trapeziometacarpal arthrosis.

  15. Psychological therapy for psychogenic amnesia: Successful treatment in a single case study. (United States)

    Cassel, Anneli; Humphreys, Kate


    Psychogenic amnesia is widely understood to be a memory impairment of psychological origin that occurs as a response to severe stress. However, there is a paucity of evidence regarding the effectiveness of psychological therapy approaches in the treatment of this disorder. The current article describes a single case, "Ben", who was treated with formulation-driven psychological therapy using techniques drawn from cognitive behavioural therapy (CBT) and acceptance and commitment therapy (ACT) for psychogenic amnesia. Before treatment, Ben exhibited isolated retrograde and anterograde memory impairments. He received 12 therapy sessions that targeted experiential avoidance followed by two review sessions, six weeks and five months later. Ben's retrograde and anterograde memory impairments improved following therapy to return to within the "average" to "superior" ranges, which were maintained at follow-up. Further experimental single case study designs and larger group studies are required to advance the understanding of the effectiveness and efficacy of psychological therapy for psychogenic amnesia.

    Deguy, M; Genre, C; Debaere, P A


    45 patients considering cosmetic surgery underwent two graphological tests; the first prior to their operation, the second approximately six months afterwards. The results of these tests show that the patients have a number of elements in common depending on the type of operation performed and reveal several psychological aspects specific to subjects likely to envisage cosmetic surgery. However, the second graphological analysis showed no significant changes in any of the patients. The tests are simple and easily accepted by prospective subjects and enable a better psychological approach between patient and practicians.

  19. Implications for better nursing practice: psychological aspects of patients undergoing post-operative wound care. (United States)

    Murakami, Reiko; Shiromaru, Mizue; Yamane, Reiko; Hikoyama, Hiroko; Sato, Mikiyo; Takahashi, Natsuko; Yoshida, Sumie; Nakamura, Misuzu; Kojima, Yoshikazu


    To understand the psychological aspects in patients undergoing post-operative wound care and to gain insights for improving nursing practice. Very few studies have examined education on or practice of wound care with a view towards the patient's psychology. Descriptive exploratory qualitative study. Four patients who had undergone open surgery of the upper gastrointestinal tract were interviewed using a semi-structured format to gain an understanding of their feelings and opinions with regard to wound care. Interview transcripts were analysed using an inductive coding approach. Fifteen categories of responses were finally identified from the data. Patients wanted nursing staff to observe their wound more often so that patients could recognise improvement, to have better knowledge of the patient's disease and condition, to explain the patient's situation more completely and to appropriately answer questions. Patients also said that they felt more comfortable in posing questions or concerns regarding their condition to nursing staff than to their surgeons and did so while the wounds were being taken care of by nurses. These findings suggested the importance of nursing staff to fully understand and to be ready to share feelings regarding a patient's postoperative condition and to have skills in properly explaining the importance of each procedure or steps in treatments that a patient must undergo. The present study also indicates that it is imperative for nursing staff to learn methods to build relationships with patients so that they can express their feelings of fear or anxiety freely to nurses. It is not possible to develop nursing practice without understanding psychological aspects of patients undergoing postoperative wound care. © 2012 Blackwell Publishing Ltd.

  20. Psychological factors are closely associated with the Bell's palsy: a case-control study. (United States)

    Huang, Bo; Xu, Shabei; Xiong, Jin; Huang, Guangying; Zhang, Min; Wang, Wei


    To observe the differences in psychological status between Bell's palsy (BP) patients and healthy subjects, and to examine the relationship between psychological factors and the severity of BP, we conducted a case-control, multi-center clinical investigation. A total of 695 subjects were assigned to the case group (n=355) and the control group (n=340). House-Brackmann grading system and Facial Disability Index (FDI) were adopted to assess the BP patients; Kessler Psychological Distress Scale (K10) and 16 Personality Factor (16PF) scale were employed to evaluate the psychological distress and personality profiles of all subjects. Two independent samples t test was used to compare the differences between cases and controls, and to compare the differences among different BP patients. Pearson correlation analysis was used to examine the relationship between psychological factors and severity of facial paralysis. The results showed that psychological distress (K10) in case group (27.09±5.80) was significantly higher than that in control group (13.43±3.02) (t=-37.219, P=0.000). The scores of personality factor Warmth (A), Openness to Change (Q1), Self-Reliance (Q2) were lower in cases than in the controls (P<0.01, P<0.05, P<0.05, respectively), whereas the scores of Sensitivity (I), Vigilance (L), Apprehension (O), and Tension (Q4) were significantly higher in cases than in the controls (P<0.05, P<0.01, P<0.01, P<0.01, respectively). In addition, the psychological distress was significantly higher in female patients, severe (HB score IV-VI) patients, and subacute (onset time 72-168 h) patients compared with that in male patients, mild (HB score I-III)patients, and acute (onset time[Symbol: see text]72 h) patients (P<0.05). The scores of personality factor in female patients, severe patients, and subacute patients were also significantly different from male patients, mild patients, and acute patients (P<0.05). The result of Pearson correlation analysis showed that

    Duffy, Jeanne F.; Zitting, Kirsi-Marja; Czeisler, Charles A.


    Sleep deficiency, which can be caused by acute sleep deprivation, chronic insufficient sleep, untreated sleep disorders, disruption of circadian timing, and other factors, is endemic in the U.S., including among professional and non-professional drivers and operators. Vigilance and attention are critical for safe transportation operations, but fatigue and sleepiness compromise vigilance and attention by slowing reaction times and impairing judgment and decision-making abilities. Research studies, polls, and accident investigations indicate that many Americans drive a motor vehicle or operate an aircraft, train or marine vessel while drowsy, putting themselves and others at risk for error and accident. In this chapter, we will outline some of the factors that contribute to sleepiness, present evidence from laboratory and field studies demonstrating how sleepiness impacts transportation safety, review how sleepiness is measured in laboratory and field settings, describe what is known about interventions for sleepiness in transportation settings, and summarize what we believe are important gaps in our knowledge of sleepiness and transportation safety.

  3. Self-castration by a transsexual woman: financial and psychological costs: a case report. (United States)

    St Peter, Matthew; Trinidad, Anton; Irwig, Michael S


    The out-of-pocket cost for an elective orchiectomy, which is often not covered by health insurance, is a significant barrier to male-to-female transsexuals ready to proceed with their physical transition. This and other barriers (lack of access to a surgeon willing to perform the operation, waiting times, and underlying psychological and psychiatric conditions) lead a subset of transsexual women to attempt self-castration. Little information has been published on the financial costs and implications of self-castration to both patients and health care systems. We compare the financial and psychological costs of elective surgical orchiectomy vs. self-castration in the case of a transsexual woman in her 40s. We interviewed the patient and her providers and obtained financial information from local reimbursement and billing specialists. After experiencing minor hemorrhage following the self-castration, our patient presented to the emergency department and underwent a bilateral inguinal exploration, ligation and removal of bilateral spermatic cords, and complicated scrotal exploration, debridement, and closure. She was admitted to the psychiatric service for a hospital stay of three days. The total bill was U.S. $14,923, which would compare with U.S. $4,000 for an elective outpatient orchiectomy in the patient's geographical area. From a financial standpoint, an elective orchiectomy could have cost the health care system significantly less than a hospital admission with its associated additional costs. From a patient safety standpoint, elective orchiectomy is preferable to self-castration which carries significant risks such as hemorrhage, disfigurement, infection, urinary fistulae, and nerve damage. Healthcare providers of transsexual women should carefully explore patient attitudes toward self-castration and work toward improving access to elective orchiectomy to reduce the number of self-castrations and costs to the overall health care system.

  4. 'I want the way I look to matter less': A case study describing psychological aspects of changing appearance. (United States)

    Tevik, Frøydis; Feragen, Kristin Billaud


    There is a need for a better understanding of psychological processes when appearance is changed dramatically through surgery. The aim of this article is to shed light on how complex the process of changing appearance can be, and highlight the importance of including a psychological perspective to the treatment offered to children and adolescents with a visible condition affecting appearance. In order to illustrate some psychological aspects involved in a change of appearance, the case study of a young woman born with a cleft palate is presented. Through orthognathic surgery, an operation that changes the relationship and position of the upper and lower jaw, this young woman experienced a dramatic change in appearance. As a result of a new attractive appearance, she experienced new and different social interactions, which challenged her in surprising ways. Unexpectedly, an unknown past of childhood sexual abuse was triggered by romantic experiences due to her new appearance, and she developed signs of post-traumatic stress disorder (PTSD) and depression. This article presents central themes from the therapy and clinical interventions, which were mainly based on a solution-oriented and cognitive framework, and considers how the change of appearance affected the way this young woman behaved, felt and thought about herself after the surgery. Clinical implications of the case are discussed and their relevance to another research field - dramatic weight loss among those suffering from obesity - is suggested. © The Author(s) 2014.

  6. Single-case research design in pediatric psychology: considerations regarding data analysis. (United States)

    Cohen, Lindsey L; Feinstein, Amanda; Masuda, Akihiko; Vowles, Kevin E


    Single-case research allows for an examination of behavior and can demonstrate the functional relation between intervention and outcome in pediatric psychology. This review highlights key assumptions, methodological and design considerations, and options for data analysis. Single-case methodology and guidelines are reviewed with an in-depth focus on visual and statistical analyses. Guidelines allow for the careful evaluation of design quality and visual analysis. A number of statistical techniques have been introduced to supplement visual analysis, but to date, there is no consensus on their recommended use in single-case research design. Single-case methodology is invaluable for advancing pediatric psychology science and practice, and guidelines have been introduced to enhance the consistency, validity, and reliability of these studies. Experts generally agree that visual inspection is the optimal method of analysis in single-case design; however, statistical approaches are becoming increasingly evaluated and used to augment data interpretation.

  8. [Changes in psychological features in patients for anesthesia and operation during perioperative period]. (United States)

    Kunihiro, M; Somura, H; Matsumoto, M; Sakabe, T


    The purpose of this study was to assess perioperative changes in psychological features of patients receiving anesthesia and operation. Anxiety level and desire for obtaining information were evaluated in 37 patients using the Amsterdam preoperative anxiety and information scale (APAIS) at three points: before and after the preanesthetic examination, and 3 to 5 days after the operation. Anxiety scale (4-20) and information scale (2-10) scores decreased postoperatively from 9.8 +/- 3.8 to 7.3 +/- 3.4 and from 6.1 +/- 2.1 to 4.1 +/- 1.9, respectively. There was a significant but weak correlation (rs = 0.35) between the anxiety scale and information scale before the preanesthetic examination. The postoperative information scale score correlated well with preoperative anxiety scale score (rs = 0.61), and this correlation was higher than with preoperative information scale score (rs = 0.37). When patients were divided into two subgroups, namely patients with (U, n = 12) or without (non-U, n = 25) an increase in postoperative information scale score, anxiety scale score before the preanesthetic examination tended to be higher and the postoperative anxiety scale score was significantly higher in the U group than in the non-U group. We conclude that we should provide more information to the patients who have higher anxiety scale score before the preanesthetic examination regardless of their degree of desire for information.

  9. Risk Factors for Farmers' Suicides in Central Rural India: Matched Case-control Psychological Autopsy Study. (United States)

    Bhise, Manik Changoji; Behere, Prakash Balkrushna


    Despite more than two decades since recognition of suicides by farmers in India, systematic studies comparing various risk factors are lacking. This is major hurdle for the formulation of strategies for farmers' suicide prevention. To identify socioeconomic and psychological risk factors and their relative contribution in suicides by farmers. A matched case-control psychological autopsy was done on 98 farmers' suicide victims and 98 controls in Central India. Economic problems, psychiatric illness, and stressful life events were found to be important contributors to farmers' suicides. Important economic risk factors were procurement of debt, especially from multiple sources and for nonagricultural reasons and leasing out farms. Psychiatric illness was present significantly in higher proportion among cases than controls. Crop failure, interpersonal problems, medical illness, and marriage of female family member were significant stressful life events. There are socioeconomic and psychological risk factors for suicide by farmers which can be targets of prevention policy.

  11. Popular evolutionary psychology in the UK: an unusual case of science in the media? (United States)

    Cassidy, Angela


    This paper presents findings from quantitative analyses of UK press and print media coverage of evolutionary psychology during the 1990s. It argues that evolutionary psychology presents an interesting case for studies of science in the media in several different ways. First, press coverage of evolutionary psychology was found to be closely linked with the publications of popular books on the subject. Secondly, when compared to coverage of other subjects, a higher proportion of academics and authors wrote about evolutionary psychology in the press, contributing to the development of a scientific controversy in the public domain. Finally, it was found that evolutionary psychology coverage appeared in different areas of the daily press, and was rarely written about by specialist science journalists. The possible reason for these features are then explored, including the boom in popular science publishing during the 1990s, evolutionary psychology's status as a new subject of study and discussion, and the nature of the subject its as theoretically based and with a human, "everyday" subject matter.

  1. Murky Projects and Uneven Information Policies: A Case Study of the Psychological Strategy Board and CIA

    Directory of Open Access Journals (Sweden)

    Susan Maret


    Full Text Available This case study discusses the Truman and Eisenhower administration's (1951-1953 short-lived Psychological Strategy Board (PSB. Through the lens of declassified documents, the article recounts the history and activities of the Board, including its relationship with the Central Intelligence Agency (CIA and clandestine projects that involve human experimentation. Primary documents of the period suggest that institutional secrecy, coupled with inconsistent information policies, largely shielded CIA's BLUEBIRD, ARTICHOKE, and MKULTRA from the Board. This subject has not been previously reported in the research literature, and supplements existing historical understanding of the PSB's mission under the broad umbrella of psychological warfare.

  2. A case study in Gantt charts as historiophoty: A century of psychology at the University of Alberta. (United States)

    Dawson, Michael R W


    History is typically presented as historiography, where historians communicate via the written word. However, some historians have suggested alternative formats for communicating and thinking about historical information. One such format is known as historiophoty, which involves using a variety of visual images to represent history. The current article proposes that a particular type of graph, known as a Gantt chart, is well suited for conducting historiophoty. When used to represent history, Gantt charts provide a tremendous amount of information. Furthermore, the spatial nature of Gantt charts permits other kinds of spatial operations to be performed on them. This is illustrated with a case study of the history of a particular psychology department. The academic year 2009-2010 marked the centennial of psychology at the University of Alberta. This centennial was marked by compiling a list of its full-time faculty members for each year of its history. This historiography was converted into historiophoty by using it as the source for the creation of a Gantt chart. The current article shows how the history of psychology at the University of Alberta is revealed by examining this Gantt chart in a variety of different ways. This includes computing simple descriptive statistics from the chart, creating smaller versions of the Gantt to explore departmental demographics, and using image processing methods to provide measures of departmental stability throughout its history.

    Highlights: • A safety case incorporating technical and ITER related upgrades. • Hazard analysis reworked to include new modelling assessments. • Fitness for purpose assessment of safety controls. - Abstract: A new Safety Case is required to permit tritium operations on JET during the forthcoming DTE2 campaign. The outputs, benefits and lessons learned associated with the production of this Safety Case are presented. The changes that have occurred to the Safety Case methodology since the last JET tritium Safety Case are reviewed. Consideration is given to the effects of modifications, particularly ITER related changes, made to the JET and the impact these have on the hazard assessments as well as normal operations. Several specialized assessments, including recent MELCOR modelling, have been undertaken to support the production of this Safety Case and the impact of these assessments is outlined. Discussion of the preliminary actions being taken to progress implementation of this Safety Case is provided, highlighting new methods to improve the dissemination of the key Safety Case results to the plant operators. Finally, the work required to complete this Safety Case, before the next tritium campaign, is summarized.

  4. Single Case Method in Psychology: How to Improve as a Possible Methodology in Quantitative Research. (United States)

    Krause-Kjær, Elisa; Nedergaard, Jensine I


    Awareness of including Single-Case Method (SCM), as a possible methodology in quantitative research in the field of psychology, has been argued as useful, e.g., by Hurtado-Parrado and López-López (IPBS: Integrative Psychological & Behavioral Science, 49:2, 2015). Their article introduces a historical and conceptual analysis of SCMs and proposes changing the, often prevailing, tendency of neglecting SCM as an alternative to Null Hypothesis Significance Testing (NHST). This article contributes by putting a new light on SCM as an equally important methodology in psychology. The intention of the present article is to elaborate this point of view further by discussing one of the most fundamental requirements as well as main characteristics of SCM regarding temporality. In this respect that; "…performance is assessed continuously over time and under different conditions…" Hurtado-Parrado and López-López (IPBS: Integrative Psychological & Behavioral Science, 49:2, 2015). Defining principles when it comes to particular units of analysis, both synchronic (spatial) and diachronic (temporal) elements should be incorporated. In this article misunderstandings of the SCM will be adduced, and further the temporality will be described in order to propose how the SCM could have a more severe usability in psychological research. It is further discussed how to implement SCM in psychological methodology. It is suggested that one solution might be to reconsider the notion of time in psychological research to cover more than a variable of control and in this respect also include the notion of time as an irreversible unity within life.

  5. Rendering clinical psychology an evidence-based scientific discipline: a case study. (United States)

    St Stoyanov, Drozdstoj; Machamer, Peter K; Schaffner, Kenneth F


    Both modern neuroscience and clinical psychology taken as separate fields have failed to reveal the explanatory mechanisms underlying mental disorders. The evidence acquired inside the mono-disciplinary matrices of neurobiology, clinical psychology and psychopathology are deeply insufficient in terms of their validity, reliability and utility. Further, no effective trans-disciplinary connections have been developed between them. In this context, our case study aims at illustrating some specific facets of clinical psychology as a crucial discipline for explaining and understanding mental disorder. The methods employed in clinical psychology are scrutinized using the exemplar case of the Minnesota Multiphasic Personality Inventory (MMPI). We demonstrate that a clinical interview and a clinical psychological rating scale consist of the same kind of cognitive content. The provisional difference can be described in terms of its having two comparable complementary cognitive structures. The test is composed of self-evaluation reports (items) formulated as questions or statements. The psychopathological structured interview is formulated in terms of subjective experience indicated as symptoms (these are self-reports recorded by the physician), complemented with the so-called 'signs' or the presumably 'objective' observations of the overt behaviours of the patient. However, the cognitive content of clinical judgment is beyond any doubt as subjective as the narrative of the patient. None of the components of the structured psychopathological interview is independent of the inter-subjective system created in the situation of clinical assessment. Therefore, the protocols from various clinicians that serve to sustain the reliability claim of the 'scientific' Diagnostic Statistical Manual of Mental Disorders cannot be regarded as independent measurements of the cognitive content and value of the psychological rating scales or vice versa. © 2011 Blackwell Publishing Ltd.

  6. Bringing the (disabled) body to personality psychology: A case study of Samantha. (United States)

    Adler, Jonathan M


    Personality psychology has largely ignored the experiences of people with disabilities. This article strives to bring the thriving, interdisciplinary field of disability studies to personality psychology via a case study of Samantha (N = 1). Samantha feels that she grew up as a hearing person who could not hear and is now a deaf person who can hear. Narrative identity provides the theoretical, methodological, and analytical framework for the rich, qualitative examination of Samantha's life story, interwoven with approaches from disability studies and intersectionality theory. Two Life Story Interviews (McAdams, 2008), conducted 2 weeks prior to Samantha's cochlear implant surgery and again 7 weeks after the surgery, provide the foundation for this case study and are interpreted alongside additional self-report measures. Grounded theory methods were used to interpret Samantha's narrative identity. Samantha's story demonstrates the ways in which narrative identity can serve as a foundation for meaning and psychological well-being, as well as a demonstration of the ways in which the study of identity can be enriched by perspectives from disability studies. As an initial effort at integrating personality psychology and disability studies, this article sought to approach this task by privileging ethical representation over generalizability. © 2017 Wiley Periodicals, Inc.

  7. Causality in criminal forensic and in civil disability cases: Legal and psychological comparison. (United States)

    Young, Gerald


    Causality (or causation) is central to every legal case, yet its underlying philosophical, legal, and psychological definitions and conceptions vary. In the criminal context, it refers to establishing the responsibility of the perpetrator of the criminal act at issue in terms of the person's mental state (mens rea), and whether the insanity defense applies. In the forensic disability and related context, it refers to whether the index event is a material or contributing cause in the multifactorial array that led to the psychological condition at issue. In both the criminal and tort contexts, the legal test is a counterfactual one. For the former, it refers to whether the outcome involved would have resulted absent the act (e.g., in cases of simultaneous criminal lethal action, which one is the but-for responsible one). For the latter, it concerns whether the claimed psychological condition would be present only because of the incident at issue. The latter event at issue is distinguished from the criminal one by its negligence compared to the voluntary intent in the criminal case. The psychological state of the perpetrator of criminal conduct can be analyzed from a biopsychosocial perspective as much as the civil one. In this regard, in the civil case, such as in forensic disability and related assessments, pre-existing, precipitating, and perpetuating factors need to be considered causally, with personal and social resilience and protective factors added, as well. In the criminal context, the same biopsychosocial model applies, but with mental competence and voluntariness added as a critical factor. The advent of neurolaw has led to use of neuroscience in court, but it risks reducing the complexity of criminal cases to unifactorial, biological models. Copyright © 2015 Elsevier Ltd.

  9. Emotions and golf performance: An IZOF-based applied sport psychology case study. (United States)

    Cohen, Alexander B; Tenenbaum, Gershon; English, R William


    A multiple case study investigation is reported in which emotions and performance were assessed within the probabilistic individual zone of optimal functioning (IZOF) model (Kamata, Tenenbaum,& Hanin, 2002) to develop idiosyncratic emotion-performance profiles. These profiles were incorporated into a psychological skills training (PST) intervention, with a focus on three emotional dimensions, that is, arousal, pleasantness, and functionality, and several psychological strategies employed during practice and competition. Two female varsity golfers at a major Division I university in the Southeast participated in the case study during the Spring 2002 season. The PST intervention resulted in enhanced emotional self-regulation skills and improved golf performance. Directions for future research into the IZOF model and implications for practical application of the model are discussed.

  10. Self-perceived psychological stress and ischemic stroke: a case-control study

    Directory of Open Access Journals (Sweden)

    Blomstrand Christian


    Full Text Available Abstract Background A growing body of evidence suggests that psychological stress contributes to coronary artery disease. However, associations between stress and stroke are less clear. In this study, we investigated the possible association between ischemic stroke and self-perceived psychological stress, as measured by a single-item questionnaire, previously reported to be associated with myocardial infarction. Methods In the Sahlgrenska Academy Study on Ischemic Stroke (SAHLSIS, 600 consecutive patients with acute ischemic stroke (aged 18 to 69 years and 600 age-matched and sex-matched population controls were recruited. Ischemic stroke subtype was determined according to Trial of Org 10172 in Acute Stroke Treatment (TOAST criteria. Self-perceived psychological stress preceding stroke was assessed retrospectively using a single-item questionnaire. Results Permanent self-perceived psychological stress during the last year or longer was independently associated with overall ischemic stroke (multivariate adjusted odds ratio (OR 3.49, 95% confidence interval (CI 2.06 to 5.93. Analyses by stroke subtype showed that this association was present for large vessel disease (OR 3.91, 95% CI 1.58 to 9.67, small vessel disease (OR 3.20, 95% CI 1.64 to 6.24, and cryptogenic stroke (OR 4.03, 95% CI 2.34 to 6.95, but not for cardioembolic stroke (OR 1.48, 95% CI 0.64 to 3.39. Conclusion In this case-control study, we found an independent association between self-perceived psychological stress and ischemic stroke. A novel finding was that this association differed by ischemic stroke subtype. Our results emphasize the need for further prospective studies addressing the potential role for psychological stress as a risk factor for ischemic stroke. In such studies ischemic stroke subtypes should be taken into consideration.

  15. Three Cases of Hair Loss Analyzed by the Point of View of the Analytical Psychology. (United States)

    Leite Júnior, Ademir Carvalho; Katzer, Tatiele; Ramos, Denise Gimenez


    Psychotrichology is the science, which covers the psychosomatics applied to hair problems, i.e., body-psyche phenomena involving scalp and hair disorders. The approaches involving psychotricology are varied and may include psychiatric,[1] psychoanalytical,[23] and those involving knowledge related to analytical psychology.[4] An analysis from the analytical psychology point of view, a theory developed by the physician Carl Gustav Jung, favors a symbolic view to the disease, providing it attributions and meanings that go beyond those related to physical body signs and symptoms only. This paper aims to describe and analyze, under the analytical psychology view, three cases the psychic and clinical demonstrations of which relate to symbolic and historic aspects concerning life of patients as possibilities of cause and maintenance of hair problems. The first of them is related to an 8-year-old girl who witnessed a scene of physical aggression by her father against her mother and developed a case of total alopecia. The second case is related to a 43-year-old woman who developed self-inflicted scalp dermatitis due to severe anxiety; and at last, the case of a telogen effluvium in a 23-year-old woman who developed hyperprolactinemia after the death of her mother, having to substitute her in the care about her husband and brothers. Looking at the clinical history and symbolic matters of scalp and hair diseases enabled, in the aforementioned cases, a better understanding of patients' psychoemotional disorders that may be related to the beginning and maintenance of clinical cases presented by them.

We report a case with a rich iconography, of an annular pancreas discovered intraoperatively. A 46- year-old woman was operated with the diagnosis of acute cholecystitis with common bile duct stones. At operation, a strip of pancreatic tissue (2 cm completely encircled the second duodenum. Open cholecytectomy with choledocotomy and stones extractionwas done. Postoperatively, she developed an acute pancreatitis. The post-operative cholangiography showed the annular duct surrounding the second duodenum. Annular pancreas is rare. Symptoms may occur in newborn children. In adults, annular pancreas discovering is radiological or intra operatively.

  1. Analysis of a Clinical Case Formulation Protocol from Psychological Well-Being Categories

    Directory of Open Access Journals (Sweden)

    Claudia Consuelo Caycedo Espinel


    Full Text Available We describe the validation process of a case formulation protocol, based on the theoretical perspective of Behavior Analysis, in order to contribute to the development of a case formulation model aimed to organize the information coming from evaluation, to reduce clinical judgment bias, and to orient the clinical intervention towards a coherent and consistent way with the analysis categories belonging to the field of Psychological Wellbeing. Validity was defined as a function of the use of a single case designwith a time series methodology and the internal validity of the formulations, based on criteria of consistency among the categories and the descriptive and explicative hypotheses, and among these and the intervention plan.The clinical formulation process was finished with six cases, taking the intervention efficacy as the validity criterion. Results point to the high level of inference and hypotheses based on clinical judgment rather than on empirical evidences.

  2. Integrating Nuclear Energy to Oilfield Operations – Two Case Studies

    Energy Technology Data Exchange (ETDEWEB)

    Eric P. Robertson; Lee O. Nelson; Michael G. McKellar; Anastasia M. Gandrik; Mike W. Patterson


    Fossil fuel resources that require large energy inputs for extraction, such as the Canadian oil sands and the Green River oil shale resource in the western USA, could benefit from the use of nuclear power instead of power generated by natural gas combustion. This paper discusses the technical and economic aspects of integrating nuclear energy with oil sands operations and the development of oil shale resources. A high temperature gas reactor (HTGR) that produces heat in the form of high pressure steam (no electricity production) was selected as the nuclear power source for both fossil fuel resources. Both cases were based on 50,000 bbl/day output. The oil sands case was a steam-assisted, gravity-drainage (SAGD) operation located in the Canadian oil sands belt. The oil shale development was an in-situ oil shale retorting operation located in western Colorado, USA. The technical feasibility of the integrating nuclear power was assessed. The economic feasibility of each case was evaluated using a discounted cash flow, rate of return analysis. Integrating an HTGR to both the SAGD oil sands operation and the oil shale development was found to be technically feasible for both cases. In the oil sands case, integrating an HTGR eliminated natural gas combustion and associated CO2 emissions, although there were still some emissions associated with imported electrical power. In the in situ oil shale case, integrating an HTGR reduced CO2 emissions by 88% and increased natural gas production by 100%. Economic viabilities of both nuclear integrated cases were poorer than the non-nuclear-integrated cases when CO2 emissions were not taxed. However, taxing the CO2 emissions had a significant effect on the economics of the non-nuclear base cases, bringing them in line with the economics of the nuclear-integrated cases. As we move toward limiting CO2 emissions, integrating non-CO2-emitting energy sources to the development of energy-intense fossil fuel resources is becoming

  4. The Fatigue of Compassionate Service-Learning: A Qualitative Case Study in Community Psychology

    Directory of Open Access Journals (Sweden)

    Marco Gemignani


    Full Text Available In service-learning university courses, it is often difficult to support an effective and healthy balance between performance in the field and students’ engagement in their community service. Based on the author’s teaching experience, this article presents a qualitative case study on the experiences of compassion, fatigue, responsibilization, and identification as they were reported by students and observed in the field. I conceptualize these experiences as linked to three main themes: the students’ first practical use of psychology-related knowledge, the social construction of their professional identity, and the perceived effectiveness of their field work. This study concludes with an argument to consider experiences of compassion as constructive although challenging components of service-learning courses. I suggest interpreting psychological and relational challenges as occasions for self-knowledge, engagement with the field, and understanding of the limits of power and responsibility in community service.

  5. Approach to operational mine planning: Case study Tamnava West

    Directory of Open Access Journals (Sweden)

    Stevanović Dejan R.


    Full Text Available In contemporary mining industry is very difficult to achieve production targets and profit without investing effort in detailed excavation planning. It is especially true for deposits with complex geological structure and production technology, as is the case for many coal mines in Serbia. The majority of coal production is used for generation of electricity in power plant. This fact is the main reason why production objectives of coal mine and power plant are strongly connected. Due to the fluctuation of the coal quality, operational mine planning (as a part of coal homogenization process, is of critical importance for managing successful coal quality control and meeting criteria of power plant. This paper investigates advantage of proper operational planning on coal quality control process and overall production performance. For better understanding case study is conducted on open pit Tamnava West field. Successful operational mine planning is almost impossible without use of modern software packages. For that reason in presented case study operational mine planning is done with Minex software.

  6. New drilling methods for the conductor casing operations

    Rafał Wiśniowski


    Full Text Available The necessity to apply casing to wells drilled in loose rock strata have recently created conditions for the modernization of old solutions and the development of new drilling technologies. The newest World's design and technological solutions for rotary, rotary-percussion and percussion drillings are presented in the paper with a further development directions indicated. An emphasis is put on the comparison of frequently diversified technologies basing on the concurrent drilling and the casing operations. In the course of an analysis of distribution of forces acting on the casing, the strength conditions were specified to enable a proper selection of physical properties and geometrical parameters of pipes. An exemplary calculation indicates that axial forces and torque have an influence on the selection of the outer diameter of casing made of various materials.

  8. Physical and psychological work demands as potential risk factors for musculoskeletal disorders among workers in weaving operations (United States)

    Telaprolu, Neeraja; Anne, Sharada Devi


    Aim: The study was undertaken to examine the relationship between perceived physical and psychological work demands and self reported musculoskeletal disorders (MSDs) among workers involved in weaving operations. Method: The Nordic Musculoskeletal Disorders Questionnaire and Work Demands Scale, developed and standardized for the present investigation were the tools for data collection. Chi square test was used to assess univariate associations between work demands and reported MSDs. Multiple logistic regression analysis was performed for each of the outcome MSD retaining the variables in the model to adjust for potential confounding. Results: Women were significantly more affected than men in shoulders, wrists/hands, upper back, lower back, and ankle/feet. Perceived physical and psychological demands were significantly associated with MSDs of different body regions. Pulling, pushing, moving, lifting and lowering heavy objects, working while bent or twisted at the waist, and repetitive motions with hands/wrists were the main physical factors retained in the regression models with odds ratios greater than 2. Conflicting demands, work is not remunerative, and no sufficient time to get the job done were the main psychological factors retained in the regression models with odds ratios greater than 1.68. Gender was found to be a significant factor for shoulders, wrists/hands, lower back, and ankles/feet with odds ratios ranging from 1.71 to 2.14. MSDs occurrence was more probable in the mentioned regions among women as compared to men. Both physical and psychological work demands in the work environment were contributing factors for developing MSDs among workers involved in weaving operations. PMID:25598618

    Full Text Available The efficacy of forensic evaluation of the psychological injury based on the MMPI-2 and a clinical interview has been continuously supported by literature. Nevertheless, there is no evidence of the efficacy of the MMPI for adolescents (MMPI-A for bullying cases. To contrast the efficacy of the MMPI-A in bullying cases, 107 adolescents ranged from 14 to 18 years old (M = 14.85 endorsed the Spanish adaptation of the MMPI-A under standard and malingering instructions. The results showed a high adolescent ability (91.6% for posttraumatic stress disorder, ranging from 60 to 90% for comorbid posttraumatic stress disorders to malinger both the direct (posttraumatic stress disorder and indirect (depression, anxiety, psychosomatic problems, problems in interpersonal relationships psychological injury. Four malingering strategies were identified in malingering protocols: indiscriminate symptom endorsement, symptom severity, obvious symptoms, and infrequent symptoms. The F, F1, F2 and K standard validity scales discriminated significantly and with a large effect size between genuine and malingered responding. Likewise, the F-K index and the L and K less than 45 and F less than 80 profile discriminated significantly and with a large effect size between genuine and malingered responding. The study of cases revealed excellent classification rates of the standard validity scales (K less than 40 and indices for malingered (true positives and honest (false positives responding. Implications for forensic practice are discussed.

  13. Politics, operant conditioning, Galileo, and the American Psychological Association's response to Rind et al. (1998). (United States)

    Baird, Brian N


    The controversy surrounding B. Rind, P. Tromovitch, and R. Bauserman (1998) provides valuable lessons into scientific independence, politics, and organizational decision making. In an unprecedented action, the U.S. Congress officially condemned findings of Rind et al. Meanwhile, the American Psychological Association took similarly unprecedented measures in an effort to assuage its Congressional critics. This article, written from the perspective of a psychologist serving in Congress, discusses the various political and organizational dynamics that developed during the controversy. Understanding and learning from this incident can help psychologists and their professional associations better prepare for and respond to potential controversies arising from research or other publications.

  15. Responding to Trauma at Sea: A Case Study in Psychological First Aid, Unique Occupational Stressors, and Resiliency Self-Care. (United States)

    Millegan, Jeffrey; Delaney, Eileen M; Klam, Warren


    The U.S. Navy deploys Special Psychiatric Rapid Intervention Teams (SPRINT) to sites of military disasters to assist survivors and the command. SPRINT functions primarily as a consultant to help commands effectively respond to the mental health needs of their service members following a traumatic event. Utilizing the principles of psychological first aid, the overall goal of SPRINT is to mitigate long-term mental health dysfunction and facilitate recovery at both the individual and unit level. We present a case study of a SPRINT mission to a deployed U.S. Navy ship in response to a cluster of suicides and subsequent concerns about the well-being of the remaining crew. Throughout this mission, important themes emerged, such as the impact of accumulated operational stressors and the subsequent development of mental health stigma. Also, this case study demonstrates the potential effectiveness of introducing resiliency self-care meditation training to remote environments that lack ready access to mental health resources. From here, SPRINT can provide a model for immediate disaster mental health response that has potential relevancy beyond the military.

  16. Manipulative and rehabilitative therapy as a treatment of idiopathic scoliosis without psychological sequelae: a case report. (United States)

    Villafañe, Jorge H; Silva, Guillermo B; Dughera, Andrea


    The purpose of this case report is to describe management and outcomes of a patient with scoliosis. A 9-year-old female patient with a double curve pattern with Cobb angles of 18° and 24° (thoracic/thoracolumbar) compatible with scoliosis presented for physical therapy treatment. Physiotherapy treatment with a combination of manipulative and rehabilitation techniques was used. After finishing the treatment, the patient had Cobb angles of 7° and 11°, an improvement of 55% and 54%, respectively. After 6 months, these effects were maintained, as the patient had Cobb angles of 11° and 11°. The clinical appearance of the patient improved after the course of care. The patient was evaluated for psychological outcomes by applying the following tests: Scoliosis Research Society 22, Bad Sobernheim Stress, and the Brace Questionnaire The patient had the maximum score in all tests at the conclusion of therapy. The patient responded favorably to manipulative and rehabilitation techniques. At the end of care, the patient did not show psychological sequelae with selected outcome measures.

  19. Operation Joint Endeavor in Bosnia: telemedicine systems and case reports. (United States)

    Calcagni, D E; Clyburn, C A; Tomkins, G; Gilbert, G R; Cramer, T J; Lea, R K; Ehnes, S G; Zajtchuk, R


    For the last several years the U.S. Department of Defense (DoD) has operated a telemedicine test bed at the U.S. Army Medical Research and Material Command's Medical Advanced Technology Management Office. The goal of this test bed is to reengineer the military health service system from the most forward deployed forces to tertiary care teaching medical centers within the United States by exploiting emerging telemedicine technologies. The test bed has conducted numerous proof-of-concept telemedicine demonstrations as part of military exercises and in support of real-world troop deployments. The most ambitious of those demonstrations is Primetime III, an ongoing effort to provide telemedicine and other advanced technology support to medical units supporting Operation Joint Endeavor in Bosnia. Several of the first instances of the clinical use of the Primetime III systems are presented as case reports in this paper. These reports demonstrate capabilities and limitations of telemedicine. The Primetime III system demonstrates the technical ability to provide current telecommunications capabilities to medical units stationed in the remote, austere, difficult-to-serve environment of Bosnia. Telemedicine capabilities cannot be used without adequate training, operations, and sustainment support. Video consultations have eliminated the need for some evacuations. The system has successfully augmented the clinical capability of physicians assigned to these medical units. Fullest clinical utilization of telemedicine technologies requires adjustment of conventional clinical practice patterns.

  20. The American Psychological Association's response to Brown v. Board of Education. The case of Kenneth B. Clark. (United States)

    Benjamin, Ludy T; Crouse, Ellen M


    In 1954, in Brown v. Board of Education, the Supreme Court struck down the "separate but equal" doctrine of the Plessy v. Ferguson decision (1896) that was the foundation of school segregation in 17 states and the District of Columbia. Brown is arguably the most important Supreme Court decision of the 20th century in terms of its influence on American history. Moreover, it has a special significance for psychology because it marked the first time that psychological research was cited in a Supreme Court decision and because social science data were seen as paramount in the Court's decision to end school segregation. This article describes psychologist Kenneth B. Clark's role in that case and the response of the American Psychological Association to scientific psychology's moment in a great spotlight.

  4. Rainfall thresholds and flood warning: an operative case study

    Directory of Open Access Journals (Sweden)

    V. Montesarchio


    Full Text Available An operative methodology for rainfall thresholds definition is illustrated, in order to provide at critical river section optimal flood warnings. Threshold overcoming could produce a critical situation in river sites exposed to alluvial risk and trigger the prevention and emergency system alert. The procedure for the definition of critical rainfall threshold values is based both on the quantitative precipitation observed and the hydrological response of the basin. Thresholds values specify the precipitation amount for a given duration that generates a critical discharge in a given cross section and are estimated by hydrological modelling for several scenarios (e.g.: modifying the soil moisture conditions. Some preliminary results, in terms of reliability analysis (presence of false alarms and missed alarms, evaluated using indicators like hit rate and false alarm rate for the case study of Mignone River are presented.

  5. Case review analysis of operating room decisions to cancel surgery. (United States)

    Chang, Ju-Hsin; Chen, Ke-Wei; Chen, Kuen-Bao; Poon, Kin-Shing; Liu, Shih-Kai


    Cancellation of surgery close to scheduled time causes a waste of healthcare resources. The current study analyzes surgery cancellations occurring after the patient has been prepared for the operating room, in order to see whether improvements in the surgery planning process may reduce the number of cancellations. In a retrospective chart review of operating room surgery cancellations during the period from 2006 to 2011, cancellations were divided into the following categories: inadequate NPO; medical; surgical; system; airway; incomplete evaluation. The relative use of these reasons in relation to patient age and surgical department was then evaluated. Forty-one percent of cancellations were for other than medical reasons. Among these, 17.7% were due to incomplete evaluation, and 8.2% were due to family issues. Sixty seven percent of cancelled cases eventually received surgery. The relative use of individual reasons for cancellation varied with patient age and surgical department. The difference between cancellations before and after anesthesia was dependent on the causes of cancellation, but not age, sex, ASA status, or follow-up procedures required. Almost half of the cancellations were not due to medical reasons, and these cancellations could be reduced by better administrative and surgical planning and better communication with the patient and/or his family.

  6. Reassessment of psychological distress and post-traumatic stress disorder in United States Air Force Distributed Common Ground System operators. (United States)

    Prince, Lillian; Chappelle, Wayne L; McDonald, Kent D; Goodman, Tanya; Cowper, Sara; Thompson, William


    The goal of this study was to assess for the main sources of occupational stress, as well as self-reported symptoms of distress and post-traumatic stress disorder among U.S. Air Force (USAF) Distributed Common Ground System (DCGS) intelligence exploitation and support personnel. DCGS intelligence operators (n=1091) and nonintelligence personnel (n = 447) assigned to a USAF Intelligence, Surveillance, and Reconnaissance Wing responded to the web-based survey. The overall survey response rate was 31%. Study results revealed the most problematic stressors among DCGS intelligence personnel included high workload, low manning, as well as organizational leadership and shift work issues. Results also revealed 14.35% of DCGS intelligence operators' self-reported high levels of psychological distress (twice the rate of DCGS nonintelligence support personnel). Furthermore, 2.0% to 2.5% self-reported high levels of post-traumatic stress disorder symptoms, with no significant difference between groups. The implications of these findings are discussed along with recommendations for USAF medical and mental health providers, as well as operational leadership.

  9. Laparobotic Duodenal Diverticulectomy: A Case Series and Operative Technique

    Directory of Open Access Journals (Sweden)

    Anuchit Lerstsirithong


    Full Text Available Objective: Duodenal diverticulum is not uncommon but most are asymptomatic. Surgery is recommended only for the patients with symptoms. Although laparoscopic diverticulectomy can be done, it is often with significant difficulties due to inherent limitations of the laparoscopic technique and posterior location of the lesion. The advent of the robotic surgical technology with superior imaging and instrumentation may provide an alternative minimally invasive approach for this situation. We herein report our case series utilizing the daVinci Surgical System (dVSS for duodenal diverticulectomy. Methods: We retrospectively reviewed our robotic database for all duodenal procedures performed at a single institution (the Valley Hospital: VH. Only patients who underwent laparobotic duodenal diverticulectomy (LRDD were included and their recorded videos reviewed. Data analyzed were patients’ demographic, perioperative outcomes, and technical details. We used the daVinci Si (Intuitive Surgical Inc. Sunny Vale, Calif. for all cases. Results: 4 female patients underwent LRDD. All presented with abdominal pain. Diagnosis was made by CT scans or MRI with or without EGD. 3 patients had diverticula located in the second part of the duodenum (75%. Concomitant procedures (choledochoduodenostomy and CBD exploration were performed in two patients. Mean operative time was 142.5 min. There was one complication but no mortality. Average length of stay was 4 days. Conclusion: LRDD is feasible, efficient, and safe. The dVSS provides the surgeon improved visualization and enhanced dexterity to perform complex procedure.

    Full Text Available We set out to carry out a case-control evaluation of psychological distress and emotional pain among adult attendees of a Nigerian dental clinic. A total of 201 subjects, made up of 101 dental patients (test group matched with age and sex with 100 normal subjects (controls, was recruited into the study. All participants completed a designed socio-demographic questionnaire. General Health Question naire and Psyche ache Assessment Schedule were also administered to assess psychological distress based on cut-off scores ≥3 and emotional pain based on cut-off scores ≥28 respectively. The mean ages of study and control group were 33 (±12 and 36 (±13 years respectively, and both study and control groups were not significantly different in all the assessed socio-demographic parameters. Overall, 21.8% (n=22 of the subjects had psychological distress, while only 7% of the control group had psychological distress. This difference was statistically significant (P=0.003. Similarly, there was significant difference in the experience of psyche ache (unbearable psychological pain as over a third of the dental patients (37.6%, n=38 had emotional pain, while only 13% of the controls experienced psych ache (P<0.001. In this study, the burden of psychological distress and emotional pain was many-fold in dental patients when compared with the controls.

  11. Psychology and the politics of same-sex desire in the United States: an analysis of three cases. (United States)

    Hammack, Phillip L; Windell, Eric P


    Psychological science has assumed an increasingly explicit role in public policies related to same-sex desire in the United States. In this article, we present a historical analysis of the relationship between policy discourse and scientific discourse on homosexuality produced within U.S. psychology over the 20th and early 21st centuries through the lens of three cases: Bowers v. Hardwick (1986), Lawrence v. Texas (2003), and Perry v. Schwarzenegger (2010). Our analysis suggests that, for the majority of its disciplinary history, psychology produced knowledge that supported a status quo of legal and cultural subordination for same-sex-attracted individuals. The discipline's shift in understanding of homosexuality, reflected in a 1975 policy statement of the American Psychological Association, reversed this relationship and opened up space for advocacy for social and political change regarding homosexuality. Our analysis of policy decisions rendered by the courts reveals the increasingly important role psychological science has assumed in challenging the legal subordination of same-sex-attracted individuals, though the basis upon which psychological science has sought to inform policy remains limited. We conclude with a critical discussion of the type of knowledge claims psychologists have traditionally used to advocate for gay and lesbian rights, suggesting the vitality of a narrative approach which can reveal the meaning individuals make of legal subordination and political exclusion.

  12. Psychological autopsy and necropsy of an unusual case of suicide by intravenous toluene. (United States)

    Kulkarni, Ranganath R; Hemanth Kumar, R G; Kulkarni, Pratibha R; Kotabagi, Raghavendra B


    Toluene (methylbenzene; volatile hydrocarbon) is an industrial solvent that causes major injury to the lungs; the organ being the first capillary bed encountered. We report an unusual case of suicide by a 24-year-old male, paramedical professional, with fatal outcome within 16 h of intentional, intravenous self-administration of toluene, with clinical presentation of acute respiratory distress syndrome. Psychological autopsy revealed severe depressive disorder and solvent (inhalant) abuse, with marital disharmony as the precipitating stressor for suicide. Necropsy revealed diffuse congestion of internal organs like lungs and liver, epicardial petechial hemorrhages, and gastric hemorrhages. Treatment of toluene poisoning includes supportive care as no specific antidote is available. Early and aggressive management may be conducive to a favorable outcome with minimal residual pulmonary sequelae. Relevant literature of toluene poisoning was identified via PubMed, PubChem, ToxNet, Hazardous Substances Data Bank (HSDB), Embase, and PsycINFO. To our knowledge, this is the first case of suicide by intravenous administration of toluene in the literature.

  15. Psychological barriers in long term non-operative treatment of retroperitoneal hematoma

    Directory of Open Access Journals (Sweden)

    Bogdan Socea


    Full Text Available The retroperitoneal hematoma can have, mainly, a traumatic etiology - blunt abdominal trauma (falls from height, road accidents, aggression of any kind, etc., or open (incised wounds, puncture, penetration or gunshot wounds. Ruptured arterial aneurysms can cause hemorrhage in the retroperitoneal space. There is also spontaneous retroperitoneal trauma in patients with chronic treatment with anticoagulant or antiaggregant drugs (1. Hemorrhage in the retroperitoneal space can be iatrogenic, after surgical, open or laparoscopic, interventions (2, 3. A particular type of retroperitoneal hematoma is the psoas muscle hematoma in patients with chronic oral anticoagulant treatment (Acenocumarol, Warfarin. The management of the retroperitoneal hematoma, whatever the cause may be, is, for most of the time, difficult. In case of traumatic etiology, the retroperitoneal hematoma is not the only lesion, being frequently associated with severe hollow or parenchymal organs injury or vascular lesions, which highlights the importance of a complete and precise clinical inventory of the lesions. The decision between an aggressive, surgical or interventional attitude and a conservative one, with monitoring, is often taken under pressure. Especially difficult are the cases in which the imaging results of the lesions is uncertain, when the patient presents hemodynamic instability, when other lesions can not be excluded, or when the parietal peritoneum is ruptured and the retroperitoneal hematoma gets into the peritoneal cavity, the patient presenting haemoperitoneum. For most of the time, these cases have indication for exploratory laparotomy, for a diagnostic, not therapeutic, goal.

  16. Patients with psychological ICPC codes in primary care; a case-control study investigating the decade before presenting with problems. (United States)

    Gidding, Luc G; Spigt, Mark G; Dinant, Geert-Jan


    Recognizing patients with psychological problems can be difficult for general practitioners (GPs). Use of information collected in electronic medical records (EMR) could facilitate recognition. To assess relevant EMR parameters in the decade before patients present with psychological problems. Exploratory case-control study assessing EMR parameters of 58 228 patients recorded between 2013 and 2015 by 54 GPs. We compared EMR parameters recorded before 2014 of patients who presented with psychological problems in 2014 with those who did not. In 2014, 2406 patients presented with psychological problems. Logistic regression analyses indicated that having registrations of the following statistically significant parameters increased the chances of presenting with psychological problems in 2014: prior administration of a depression severity questionnaire (odds ratio (OR): 3.3); fatigue/sleeping (OR: 1.6), neurological (OR: 1.5), rheumatic (OR: 1.5) and substance abuse problems (OR: 1.5); prescriptions of opioids (OR: 1.3), antimigraine preparations (OR: 1.5), antipsychotics (OR: 1.7), anxiolytics (OR: 1.4), hypnotics and sedatives (OR: 1.4), antidepressants (OR: 1.7), and antidementia drugs (OR: 2.1); treatment with minimal interventions (OR: 2.2) and physical exercise (OR: 3.3), referrals to psychology (OR: 1.5), psychiatry (OR: 1.6), and psychosocial care (OR: 2.1); double consultations (OR: 1.2), telephone consultations (OR: 1.1), and home visits (OR: 1.1). This study demonstrates that possible indications of psychological problems can be identified in EMR. Many EMR parameters of patients presenting with psychological problems were different compared with patients who did not.

  17. Narcissistic Personality Disorder in Clinical Health Psychology Practice: Case Studies of Comorbid Psychological Distress and Life-Limiting Illness. (United States)

    Kacel, Elizabeth L; Ennis, Nicole; Pereira, Deidre B


    Narcissistic Personality Disorder (NPD) is characterized by a persistent pattern of grandiosity, fantasies of unlimited power or importance, and the need for admiration or special treatment. Individuals with NPD may experience significant psychological distress related to interpersonal conflict and functional impairment. Research suggests core features of the disorder are associated with poor prognosis in therapy, including slow progress to behavioral change, premature patient-initiated termination, and negative therapeutic alliance. The current manuscript will explore challenges of working with NPD within the context of life-limiting illness for two psychotherapy patients seen in a behavioral health clinic at a large academic health science center. The ways in which their personality disorder affected their illness-experience shared significant overlap characterized by resistance to psychotherapeutic change, inconsistent adherence to medical recommendations, and volatile relationships with providers. In this manuscript we will (1) explore the ways in which aspects of narcissistic personality disorder impacted the patients' physical health, emotional well-being, and healthcare utilization; (2) describe psychotherapeutic methods that may be useful for optimizing psychosocial, behavioral, and physical well-being in individuals with co-morbid NPD and life-limiting disease; and (3) review conceptualizations of NPD from the DSM-5 alternative model for assessing personality function via trait domains.

  18. Psychological, social, and surgical factors which influence success or failure after gastric operations. (United States)

    Hulme Moir, I


    The degree of a patient's emotional maturity and the supportive value of his home, working, and recreational environments were scored by psychosociological methods preoperatively in a group of 47 patients who were intensively investigated with regard to the dumping syndrome. After surgery, the result of the operation was independently assessed as a success or a failure. At that time, a careful review was performed of each patient's clinical state, with particular reference to postgastrectomy syndromes. Positive associations were found between surgical failure and emotional instability, recorded by an Eysenck personality inventory, and scored social deprivation. Failure also correlated with the sum of the postgastrectomy syndromes and with recurrent pain, heartburn, episodic diarrhoea, and psychiatric illness in particular. The dumping syndrome itself did not contribute to failure.

  19. [A case of depression whose symptoms cured by setting her psychological base on the transcendent level]. (United States)

    Ogasawara, Masayuki; Tagami, Shinji; Inoue, Yoichi; Takeda, Masatoshi


    We report the case of a female in her 40s diagnosed with depression. She was raised by an eccentric father, suspected of having pervasive developmental disorder, and a dominant mother. After graduating from high school, she worked as a clerk in a company for twenty years or so; however, a change in her work environment made her fall into a depressive state. Her worsening depression caused her impulsive resignation and disappearance for about four months. She spent the duration of her disappearance traveling the country, with no dissociative episodes. After returning, she received treatment for depression as an inpatient for about four months. During the first month of hospitalization, she mainly complained of a depressive mood and anxiety over the prognosis of her disorder, while she made scarcely any progress in introspection. In the second month, she gradually advanced with introspective work, but, as her introspection progressed, her depressive mood became aggravated. The therapist avoided intervention to modify her cognition, and told her the following: "it is better not to persist in managing your depressive mood itself because curing depression does not mean resolving the superficial depressive mood, but to achieve a condition not directly influenced by mood." Then, at the beginning of the third month, she became aware of "the presence of God" and, at the same time, her depressive mood greatly improved. She extended her sympathy to her mother with her unfortunate life history, and expected her mother to change as she herself had experienced, but, disappointed by her mother, she experienced anxiety attacks and came to realize her own internal rage against significant persons in her life including her mother. After "the Great being" experience, she, who had formerly attended Christian church for a short time, started to read the Bible, but she still hesitated about committing herself to "religious following." One day during the last month of hospitalization, as

  20. Rethinking the early history of post-Vygotskian psychology: the case of the Kharkov school. (United States)

    Yasnitsky, Anton; Ferrari, Michel


    Between the death of Vygotsky in 1934 and the discovery of Vygotsky's work in the West in 1962, Vygotskian psychology was developed through research done by the first generation of Vygotsky's students and their followers, primarily associated with the Kharkov School. Surprisingly, these studies carried out in the 1930s, of great importance for the development of virtually all subsequent Vygotskian psychology, still remain largely unknown; this represents a significant gap in understanding the history of Vygotskian psychology as an empirical study of consciousness. This paper provides a systematic overview of the research agenda of the Kharkov group between 1931 and 1941 and provides new insights into the early development of Vygotskian psychology.

  1. Quantum generalized observables framework for psychological data: a case of preference reversals in US elections (United States)

    Khrennikova, Polina; Haven, Emmanuel


    Politics is regarded as a vital area of public choice theory, and it is strongly relying on the assumptions of voters' rationality and as such, stability of preferences. However, recent opinion polls and real election outcomes in the USA have shown that voters often engage in `ticket splitting', by exhibiting contrasting party support in Congressional and Presidential elections (cf. Khrennikova 2014 Phys. Scripta T163, 014010 (doi:10.1088/0031-8949/2014/T163/014010); Khrennikova & Haven 2016 Phil. Trans. R. Soc. A 374, 20150106 (doi:10.1098/rsta.2015.0106); Smith et al. 1999 Am. J. Polit. Sci. 43, 737-764 (doi:10.2307/2991833)). Such types of preference reversals cannot be mathematically captured via the formula of total probability, thus showing that voters' decision making is at variance with the classical probabilistic information processing framework. In recent work, we have shown that quantum probability describes well the violation of Bayesian rationality in statistical data of voting in US elections, through the so-called interference effects of probability amplitudes. This paper is proposing a novel generalized observables framework of voting behaviour, by using the statistical data collected and analysed in previous studies by Khrennikova (Khrennikova 2015 Lect. Notes Comput. Sci. 8951, 196-209) and Khrennikova & Haven (Khrennikova & Haven 2016 Phil. Trans. R. Soc. A 374, 20150106 (doi:10.1098/rsta.2015.0106)). This framework aims to overcome the main problems associated with the quantum probabilistic representation of psychological data, namely the non-double stochasticity of transition probability matrices. We develop a simplified construction of generalized positive operator valued measures by formulating special non-orthonormal bases with respect to these operators. This article is part of the themed issue `Second quantum revolution: foundational questions'.

    Full Text Available This article deals with the problems of anxiety, stress and psychological discomfort that can affect soldiers sent on asymmetric warfare operations. It is based on secondary analysis of the data of two important field researches whose results have recently (2013 been published. Although the two researches adopted different methodologies, the testimonies are fully comparable and show that soldiers from different countries and cultures display common or similar reactions when they are placed in the stress conditions that the asymmetric environment involves. The approach of the paper is drawn up in such a way as to make the reader a participating observer of the reality of such missions. It is therefore centered on the personal testimonies of the soldiers interviewed in the two researches, testimonies reported just as they are, in their simplicity and, often, drama, with comments by the author kept to a minimum in order to give readers ample opportunity to evaluate and interpret the reported texts on their own. The research data, drawn from the declarations of those directly concerned, reveal the existence of a problem of psychological distress resulting from deployment in asymmetric warfare situations that is in part different in the causes of the problems resulting from deployment in traditional combat and affects percentages of participating soldiers that are not high but definitely significant. The highest incidence appears to be constituted by problems relating to reintegration into normal social and working life upon returning from the mission. This is followed in percentage terms by anxiety situations relating to life far from the family, due in large part to a sense of powerlessness for the scant possibility of managing family situations that may have cropped up or already existed beforehand.

  3. Operative management of acute pavement burns: a case series. (United States)

    Silver, A G; Zamboni, W A; Baynosa, R C


    Acute burns suffered from contact with environmentally heated roadways and walkways are a rare entity. The aim of this report is to assess the information gained from the treatment of a series of patients. A retrospective review of a consecutive series of cases, where operative treatment was necessary, that occurred during July 2010 in southern Arizona. Seven patients were included, with an average total body surface area burn of 10.2%. Direct fascial excision and tangential excision were carried out on three and four patients, respectively. Although tangential excision was carried out to normal endpoints, there was commonly a need for repetitive debridement. The total hospital costs were over $4,400,000 (£2,730,000). Burns suffered from contact with roadways/walkways are often deeper than suggested by their appearance. Direct fascial excision minimises the number of debridement sessions. We hypothesise that the failure to offload pressure on these wounds may be a causative factor in their observed deepening.

  4. Techniques Used in Forensic Psychological Examinations in Cases of Child and Adolescent Sexual Abuse

    Lara Lages Gava


    Full Text Available Currently, there is no standardized protocol for the evaluation of situations of sexual abuse. Thus, this study investigated the techniques used by psychologists in forensic examinations in cases of suspected child and adolescent sexual abuse in the context of the criminal investigation. Semi-structured interviews, which were qualitatively analyzed using the WebQDA software, were applied with twelve psychologists who work as expert witnesses in the Medical-Legal Institute of six Brazilian capitals. The results showed a diversity of actions taken in the forensic examination practice, as well as consensus and controversy regarding the use of psychological testing and the credibility assessment of the report. Flexibility in conducting the forensic examinations by the teams was also observed, with the techniques used adapted according to the needs. The importance of the diversity of techniques was highlighted, as these aim to assist the expert witness to come to reliable conclusions, as well as maintain the rigor and technical quality of the evaluation.

  9. Socio-Psychological Aspects of Grassroots Participation in the Transition Movement: An Italian Case Study

    Directory of Open Access Journals (Sweden)

    Fulvio Biddau


    Full Text Available In this article, we present a case study investigating the socio-psychological aspects of grassroots participation in a Transition Town Movement (TTM community initiative. We analyzed the first Italian Transition initiative: Monteveglio (Bologna, the central hub of the Italian TTM and a key link with the global Transition Network. A qualitative methodology was used to collect and analyze the data consisting of interviews with key informants and ethnographic notes. The results provide further evidence supporting the role of social representations, shared social identities, and collective efficacy beliefs in promoting, sustaining, and shaping activists’ commitment. The movement seems to have great potential to inspire and engage citizens to tackle climate change at a community level. Grassroots engagement of local communities working together provides the vision and the material starting point for a viable pathway for the changes required. Attempting to ensure their future political relevance, the TTM adherents are striving to disseminate and materially consolidate inherently political and prefigurative movement frames – primarily community resilience and re-localization – within community socio-economic and political frameworks. However, cooperation with politics is perceived by most adherents as a frustrating and dissatisfying experience, and an attempted co-optation of the Transition initiative by institutions. It highlights a tension between the open and non-confrontational approach of the movement towards institutions and their practical experience. Corresponding to this tension, activists have to cope with conflicts, contradictions, and ambivalence of social representations about community action for sustainability, which threaten the sense of collective purpose, group cohesion and ultimately its survival.

  10. Five Alzheimer's disease cases with refractory behavioural psychological symptoms of dementia treated with blonanserin. (United States)

    Hamuro, Atsushi; Saito, Satona


    The aim of the present study was to determine the efficacy, side-effects and tolerability of blonanserin for treating refractory behavioural psychological symptoms of dementia (BPSD). The present study was a 12-week, prospective, structured clinical trial of blonanserin for the treatment of BPSD. The degree of cognitive function, activities of daily living score, and the degree of BPSD were determined using the Mini-Mental State Examination (MMSE), Disability Assessment for Dementia (DAD), Neuropsychiatric Inventory (NPI) and the Rating Scale for Aggressive Behaviour in the Elderly (RAGE). The severity of extrapyramidal symptoms was assessed using the Drug-Induced Extrapyramidal Symptoms scale (DIEEPS). Five patients were enrolled. These patients met the NINCDS-ADRDA criteria. The patients were prescribed more than two kinds of existing antipsychotic drugs and were considered refractory cases; the drugs were discontinued because they were ineffectual and side-effects appeared. Each drug was prescribed independently for at least 2 weeks. The mean changes (at baseline and at the last week, respectively) in the MMSE (12.25, 9.25), in the DAD (6.5, 6.75), in the RAGE (5.5, 5.3) and in the DIEEPS (0.5, 1.5) were minimal. The mean changes in the NPI were two or fewer points. Some side-effects (one gait abnormality and one pneumonia) were observed. The results of this preliminary study show that blonanserin does not have adequate efficacy for the treatment of refractory BPSD. © 2010 The Authors.

  11. Best research practices in psychology: Illustrating epistemological and pragmatic considerations with the case of relationship science. (United States)

    Finkel, Eli J; Eastwick, Paul W; Reis, Harry T


    In recent years, a robust movement has emerged within psychology to increase the evidentiary value of our science. This movement, which has analogs throughout the empirical sciences, is broad and diverse, but its primary emphasis has been on the reduction of statistical false positives. The present article addresses epistemological and pragmatic issues that we, as a field, must consider as we seek to maximize the scientific value of this movement. Regarding epistemology, this article contrasts the false-positives-reduction (FPR) approach with an alternative, the error balance (EB) approach, which argues that any serious consideration of optimal scientific practice must contend simultaneously with both false-positive and false-negative errors. Regarding pragmatics, the movement has devoted a great deal of attention to issues that frequently arise in laboratory experiments and one-shot survey studies, but it has devoted less attention to issues that frequently arise in intensive and/or longitudinal studies. We illustrate these epistemological and pragmatic considerations with the case of relationship science, one of the many research domains that frequently employ intensive and/or longitudinal methods. Specifically, we examine 6 research prescriptions that can help to reduce false-positive rates: preregistration, prepublication sharing of materials, postpublication sharing of data, close replication, avoiding piecemeal publication, and increasing sample size. For each, we offer concrete guidance not only regarding how researchers can improve their research practices and balance the risk of false-positive and false-negative errors, but also how the movement can capitalize upon insights from research practices within relationship science to make the movement stronger and more inclusive.

    Alcohol use disorder is a well-known risk factor for suicide, as alcohol problems can deteriorate the medical and psychosocial conditions of individuals. Furthermore, the pharmacological effect of alcohol can cause impulsive behavior in individuals. However, few studies have investigated the association of alcohol problems with suicide in Japan. The purpose of the present study was to investigate psychosocial and psychiatric features of suicide-completers with alcohol problems in last one year before their death. Since December 2007, we have been conducting a Japan-wide study on suicide-completers using a psychological autopsy method, a semi-structured interview by a psychiatrist and a mental health professional including a public health nurse with the closest bereaved. Items questioned included family environment, suicide situation, history of life, labor situation, economic problems, and psychiatric diagnosis according to DSM-IV criteria at the time of death. As of December 2009, we had collected psychosocial and psychiatric information about 76 Japanese suicide cases. 16 suicide-completers with alcohol problems ("Alcohol problem" group 21.1%) were all males and almost middle-aged workers. The percentages of debt and accident proneness in "Alcohol problem" group were significantly higher than "Non-alcohol problem" group. In "Alcohol problem group", none of them have had treatment of alcohol dependence. The prevalence of alcohol use disorders in "Alcohol problem group" was significantly higher than in "Nonalcohol problem" group (81.2% vs. 0%). The findings of the present study suggest that it is important to improvement of psychiatric care in alcohol dependence for prevention future suicides among alcoholics. Furthermore, enlightenment the association between alcohol problems and suicide to the public and medical doctors is required.

  13. A Case Study of Sexual Abuse and Psychological Correlates among an HIV-Serodiscordant Couple. (United States)

    Wyatt, Gail E; Loeb, Tamra B; Williams, John K; Davis, Teri D; Zhang, Muyu


    Childhood sexual abuse (CSA), adult sexual abuse (ASA) and intimate partner violence (IVP) are documented risk factors for HIV infection and are often implicated in the presentation of mental health disorders in both males and females, including those who are vulnerable to HIV-infection (African-Americans; trauma survivors). As such, these issues may contribute to health-related challenges among couples, particularly if the individuals are impacted by histories of trauma and HIV. Presented here is a case study of one couple with self-reported histories of CSA and clinically significant symptoms of posttraumatic stress disorder (PTSD) and depression. This couple was selected from a larger National Institute of Mental Health (NIMH)-funded study of 535 African-American HIV-serodiscordant heterosexual couples (see El Bassel, 2010). The study couple completed 8 sessions of an HIV sexual risk reduction intervention program to increase condom use. Although the couple reported an initial increase in condom use at the immediate post intervention assessment, condom use decreased to baseline assessment levels at the 12-month post intervention assessment. The decrease in HIV-transmission protective behaviors over time (i.e., condom use), in part, may be attributable to the clinically significant psychological distress symptoms of PTSD and depression that were maintained from baseline, throughout the trial, and at follow-up assessments. We propose that the success of sexual risk reduction interventions may be attenuated and compromised over time by the presence of sexual trauma histories and the residual mental health issues. We discuss clinical implications for health care professionals in their work with couples, especially those from racially diverse groups.

  14. Gestalt and Totality. The Case of Merleau-Ponty and Gestalt Psychology

    Directory of Open Access Journals (Sweden)

    Nilsen, Håvard


    Full Text Available Connected via Merleau-Ponty’s pupil Claude Lefort, Castoriadis followed many of Merleau-Ponty’s main theoretical themes, phenomenology and psychology. In this paper, a little acknowledged aspect of Merleau-Ponty’s philosophy is presented, specifically how he used Gestalt psychology as a crucial part of his theoretical project. Today, Gestalt psychology is usually only mentioned in introductory courses in psychology, in the chapters on perception. At the beginning of the 20th century, however, they were widely debated as an attempt at transforming positivism and scientific epistemology. The aim of this paper is to show a largely forgotten, but significant source of influence in intellectual history and 20th century philosophy.

    Christopher J. Wilson; Alessandro Soranzo


    Recent proliferation of available virtual reality (VR) tools has seen increased use in psychological research. This is due to a number of advantages afforded over traditional experimental apparatus such as tighter control of the environment and the possibility of creating more ecologically valid stimulus presentation and response protocols. At the same time, higher levels of immersion and visual fidelity afforded by VR do not necessarily evoke presence or elicit a “realistic” psychological r...

  17. Effect of a web-based positive psychology intervention on prenatal well-being: A case series study. (United States)

    Corno, Giulia; Etchemendy, Ernestina; Espinoza, Macarena; Herrero, Rocío; Molinari, Guadalupe; Carrillo, Alba; Drossaert, Constance; Baños, Rosa Maria


    Detrimental effects of women's negative feelings during pregnancy have been extensively examined and documented, but research on the influence of positive feelings and protective factors on their prenatal mental health is scarce. Evidence from the positive psychology field has shown that practicing some brief positive exercises, called positive psychology interventions, can maximize well-being by increasing positive emotions, engagement, and meaning. The aim of this study is to examine the effect of a positive psychology web-based intervention on indices of women's prenatal well-being. Specifically, a case series design was adopted, and data from six women are presented. Participants were involved in a 5-week online positive psychology intervention that includes a set of positive psychology interventions specifically adapted for pregnant women. Measures of women's mental well-being, depression, pregnancy-related anxiety, life satisfaction, and social support were measured at pre- and post-intervention. Compliance with the intervention and exercise preferences were assessed at post-test. Single-item related well-being measures were assessed weekly. The findings of this case series study indicate potential effects of the intervention on supporting mental well-being and decreasing depressive symptomatology in these pregnant women. Furthermore, this study provides some suggestions for developing future online-based positive interventions addressed to pregnant women. However, these findings are preliminary, and future studies are needed in order to assess the effects of the intervention in a wider population of pregnant women.

    A Omidi


    Full Text Available Introduction Measuring the efficiency of operating systems in comparison with the methods of comparing the performance of systems explains the various dimensions of issues such as, the lack of full use of agricultural machinery capacity, improper selection of machine, incorrect use of machinery, ownership, etc.. Any improvement in operating system conditions reduces costs,, consumption of inputs, increases the efficiency of production factors and consequently reduces the price and increases agricultural profitability. The main objective of this research is to compare the operational-management efficiency of operating systems in Alborz province and comparison of managerial and operational efficiency of agricultural machinery farming systems by calculating the efficiency of its major components in agricultural machinery farming systems including efficiency, social, economic, technical-operational and managerial and ranking them in order to understand the optimal model of agricultural machinery systems. Materials and Methods This research is a survey study.The study population was beneficiaries of agricultural machinery in the Alborz province which in the multi-stage random sample was determined. Alborz province has 31,438 agricultural operations, of which 543 are exploited agricultural machinery. Cochran formula was used to determine sample size. Since, Cronbach's alpha coefficient greater than 0.7 was obtained by questionnaire, the reliability of the questionnaires was assessed as desirable. To calculate the efficiency the component data were extracted from 4 specialized questionnaires after the initial examination and encoding, then they were analyzed using the software SPSS, MCDM Engine. TOPSIS techniques were used for ranking managerial performance operating system for operating agricultural machinery Alborz province. Results and Discussion The results showed that social efficiency of dedicated-professional operation with an average of 6.6 had

    Il'chenko, A A; Orlova, Iu N; Bystrovskaia, E V; Vasnev, E V; Khomeriki, S G; Vorob'eva, N N


    Adenomyomatosis (AMM) is related to the group of hyperplastic cholecystosis. Despite a long history of studying the problem, many questions concerning the etiology, pathogenesis, prevalence, tactics, management and treatment remain unsolved. To set the frequency of the AMM, its types, nature of pathological changes in the wall and lumen of gallbladder on the base of analizing the gallbladders after surgical removal. ultrasound examination, macro--and microscopic evaluation of 328 cases of the AMM gallbladders. According to ultrasound examination detection rate of AMM was 16.6%, and aacording to the study of surgical material--33%. The average age of patients 53 years old, male to female ratio--1:3,7. In 193 cases, the AMM was combined with concrements in gallbladder, in 70 cases the AMM was combined with polyps, among them in 40 patients the polyps were combined with concrements. In 175 patients we visualy analyzed the compaund of stones in gallbladder, in 112 cases there were the cholesterol stones (64%), in 51 cases--pigment stones (29.1%), in 12 patients (6.9%)--mixed. In some cases, was mentioned a combination of different AMM forms: adenomyoma on the background of diffuse adenomiomatosis--3.3%, diffuse form of AMM with more emphasized segmental lesions in one of the parts of gallbladder--6.1%, adenomyoma in one part combined with segmental lesions of another part of the gallbladder in 1.2% cases. In 64.9% cases, the AMM was combined with lipomatosis, in 56.7% cases--with the cholesterosis. The AMM is not a rare disease of gallbladder, and according to the histological examination of surgical material is detected in 31% of cases, and is oftenly combined with other types of hyperplastic cholecystosis.

    We evaluated the indications of operation and radiologic findings in 12 operated DeBakey type III aortic dissections. We retrospectively reviewed radiologic findings of 12 operated DeBakey type III aortic dissections, using CT, MRI, or aortography, and correlations were made with clinical course of the patients. Three cases were uncomplicated dissections. There were aneurysm rupture in 4 cases, impending rupture in 4 cases, occlusion of common iliac artery in 2 cases, occlusion of renal artery in 1 case, and compression of bronchus and esophagus by dilated aorta in 1 case. Associated clinical sign and symptoms were chest and back pain in 12 cases, claudication in 3 cases, dyspnea and dysphagia in 1 case, hoarseness in 1 case, and hemoptysis in 1 case. Post-operative complications were death from aneurysm rupture in 1 case, paraplegia in 2 cases, acute renal failure in 3 cases, and hemopericardium in 1 case. Although medical therapy is preferred in management of DeBakey type III aortic dissection, surgical treatment should be considered in patients with radiological findings of aortic rupture, impending rupture, occlusion of aortic major branches.

    The importance of instrument firms in the development of psychology, and science in general, should not be underestimated since it would not have been possible for various leading psychologists at the turn of the twentieth century to conduct certain experiments without the assistance of instrument makers, as is often the case today. To illustrate the historical perspective introduced here, the example of Alfred Binet is taken, as he is an interesting case of a psychologist working in close collaboration with various French instrument designers of the time. The objective of this article is twofold: (1) to show the considerable activity carried out by early psychologists to finalize new laboratory instruments in order to develop their research projects; (2) to reassess the work of a major figure in French psychology through his activity as a designer of precision instruments. The development of these new instruments would certainly have been difficult without the presence in Paris of numerous precision instrument manufacturers such as Charles Verdin, Otto Lund, Henri Collin, and Lucien Korsten, on whom Binet successively called in order to develop his projects in the field of experimental psychology. © 2016 Wiley Periodicals, Inc.

  10. "I can't let anything go:" A case study with psychological testing of a patient with pathologic hoarding. (United States)

    Koretz, Janna; Gutheil, Thomas G


    Pathologic hoarding is a symptom generally recognized as related to obsessional dynamics (Gutheil, 1959). The hoarder cannot, without great anxiety, tolerate separation from or dispose of his possessions. Thus the hoarder accumulates vast amount of possessions, often in such amounts as to compromise freedom of movement in the residence. Popular in tabloid reportage, such news items portray persons found dead among floor-to-ceiling piles of old newspapers and similar detritus, while in actual clinical practice such dramatic cases are not common (Bryk, 2005; Duenwald, 2004). More importantly, such individuals are rarely available for psychological intervention or testing, both because of social isolation and injury or death caused by the hoarded materials. Additionally, a majority of the current literature regarding hoarding is linked with Obsessive Compulsive Disorder (OCD), though other major disorders have been noted. This report describes a particular individual with characteristic features of hoarding, which is explored through formal psychological testing.

  17. Psychological assessment through performance-based techniques and self-reports: a case study of a sexually abused girl at preschool age.

    LENUS (Irish Health Repository)

    Khalily, Muhammad Tahir


    We investigated the implicit psychological and behavioral consequences of sexual abuse in an adolescent girl who suffered child sexual abuse at preschool age in this case report. We report the manifestations of this abuse on her personality and psychological functioning using a structured clinical interview and a comprehensive psychological battery including the Beck Anxiety Inventory, the Beck Depression Inventory, the Standard Progressive Matrices, Rorschach Ink Blots, and the Schema Mode Inventory. These investigations were useful in formulating both a diagnosis and a management plan. The girl fulfilled diagnostic criteria for a major depressive episode and borderline personality disorder. This combination of psychological testing may be useful in establishing an accurate multiaxial diagnosis and for understanding the behavioral and psychological sequelae of child sexual abuse in similar cases. The study further suggests that schema-focused therapy is a useful therapeutic tool for individuals who have suffered child sexual abuse at an early age and who have borderline personality disorder.

  18. Operating an Advertising Programmatic Buying Platform: A Case Study

    Directory of Open Access Journals (Sweden)

    Juan Carlos Gonzalvez-Cabañas


    Full Text Available This paper analyses how new technological developments and the possibilities generated by the internet are shaping the online advertising market. More specifically it focuses on a programmatic advertising case study. The origin of the problem is how publishers resort to automated buying and selling when trying to shift unsold inventory. To carry out our case study, we will use a programmatic online advertising sales platform, which identifies the optimal way of promoting a given product. The platform executes, evaluates, manages and optimizes display advertising campaigns, all in real-time. The empirical analysis carried out in the case study reveals that the platform and its exclusion algorithms are suitable mechanisms for analysing the performance and efficiency of the various segments that might be used to promote products. Thanks to Big Data tools and artificial intelligence the platform performs automatically, providing information in a user-friendly and simple manner.

    Yiping Chen


    Full Text Available This study was to investigate the association of psychological characteristics and functional dyspepsia treatment outcome. 109 patients who met the criteria for FD were enrolled. Eysenck Personality Questionnaire (EPQ, Symptom Checklist 90 (SCL90, and the Pittsburgh Sleep Quality Index (PSQI were used to measure personality, psychological symptoms, and sleep quality in our patients. Leeds Dyspepsia Questionnaire (LDQ was used to assess dyspeptic symptoms at baseline and after eight weeks of treatment. The LDQ scores change after therapy, and the degraded rate of LDQ was used to assess the prognosis of patients. Logistic regression model was used to assess the effect of the personality, psychological symptoms, and sleep quality on the prognosis of patients. Our result revealed that poor sleep quality (OR=7.68, 95% CI 1.83–32.25 and bad marriage status (OR=1.22, 95% CI 1.10–1.36 had the negative effect on the prognosis of FD, while extroversion in personality traits (OR=0.86, 95% CI 0.76–0.96 had positive effect on the prognosis of FD. We should pay attention to the sleep quality, the personality, and the marriage status of FD patients; psychological intervention may have benefit in refractory FD.

    Safdar, N; Hinderaker, S G; Baloch, N A; Enarson, D A; Khan, M A; Morkve, O


    The control of childhood tuberculosis (TB) has been of low priority in TB programmes in high-burden settings. The objective of this paper was to describe the development and testing of tools for the management of childhood TB. The Pakistan National TB Control Programme embarked on a number of activities, including the establishment of policy guidelines for the management of childhood TB and later a guidance document, 'Case Management Desk Guide and Structured Monitoring', to demonstrate the implementation of childhood TB interventions in a programme context. Initial results showed improved case finding and treatment outcome in implementation sites compared with control districts. However, further programme attention is required to improve quality.

    Full Text Available Aims: The aim of this study was to investigate psychological distress, anger and alexithymia in a group of patients affected by myofascial pain (MP in the facial region.Methods: 45 MP patients (mean (SD age: 38.9 (11.6 and 45 female healthy controls (mean (SD age: 37.8 (13.7 were assessed medically and psychologically. The medically evaluation consisted of muscle palpation of the pericranial and cervical muscles. The psychological evaluation included the assessment of depression (Beck Depression Inventory – short form, anxiety (State-Trait Anxiety Inventory Form Y, emotional distress (Distress Thermometer, anger (State-Trait Anger Expression Inventory - 2 and alexithymia (Toronto Alexithymia Scale.Results: the MP patients showed significantly higher scores in the depression, anxiety and emotional distress inventories. With regard to anger, only the Anger Expression-In scale showed a significant difference between the groups, with higher scores for the MP patients. In addition, the MP patients showed significantly higher alexithymic scores, in particular in the Difficulty in identifying feelings (F1 subscale of the Toronto Alexithymia Scale-20 (TAS-20. Alexithymia was positively correlated with the Anger Expression-In scale. Both anger and alexithymia showed significant positive correlations with anxiety scores, but only anger was positively correlated with depression. Conclusion: A higher prevalence of depressive and anxiety symptoms associated with a higher prevalence of alexithymia and expression-in modality to cope with anger was found in the MP patients. Because the presence of such psychological aspects could contribute to generate or exacerbate the suffering of these patients, our results highlight the need to include accurate investigation of psychological aspects in MP patients in normal clinical practice in order to allow clinicians to carry out more efficacious management and treatment strategies.

  11. Analysis to Establish Differences in Efficiency Metrics Between Operating Room and Non-Operating Room Anesthesia Cases. (United States)

    Wu, Albert; Sanford, Joseph A; Tsai, Mitchell H; O'Donnell, Stephen E; Tran, Billy K; Urman, Richard D


    While a number of studies have examined efficiency metrics in the operating rooms (ORs), there are few studies addressing non-operating room anesthesia (NORA) metrics. The standards established in the realm of OR studies may not apply to ongoing investigations of NORA efficiency. We hypothesize that there are significant differences in these commonly used metrics. Using retrospective data from a single tertiary care hospital in the 2015 calendar year, we measured turnover times, cancellation rates, first case start delays, and scheduling error (actual time minus scheduled time) for the OR and NORA settings. On average, TOTs for NORA cases were approximately 50% shorter than OR cases (16.21 min vs. 37.18 min), but had a larger variation (11.02 min vs. 8.12 min). NORA cases were 64% as likely to be cancelled compared to OR cases. In contrast, NORA cases had an average first case start delay that was two times greater than that of OR cases (24.45 min vs. 10.58 min), along with over double the standard deviation (11.97 min vs. 5.90 min). Case times for NORA settings tended to be overestimated (-4.07 min versus -2.12 min), but showed less variation (8.61 min vs. 17.92 min). In short, there are significant differences in common efficiency metrics between OR and NORA cases. Future studies should elucidate and validate appropriate efficiency benchmarks for the NORA setting.

    de Bressy de Guast, Virginie; Golby, Jim; Van Wersch, Anna; d'Arripe-Longueville, Fabienne


    This study presents a complete psychological skills training (PST) program with a wheelchair athlete and examines the program effectiveness using a mixed-method approach. After initial testing, the athlete followed a two-month program of self-confidence building, motivational, visualization/relaxation, and injury management techniques. Quantitative and qualitative methods were used to examine the impacts on performance and psychological abilities. The triangulated results suggest that the PST program was perceived as effective by the athlete in terms of his sporting performances and mental skills. The characteristics and implications of a PST program with this wheelchair athlete are discussed, as well as the study limitations and the perspectives for future research.

  15. Feasibility and utility of telephone-based psychological support for people with brain tumor: A single-case experimental study

    Directory of Open Access Journals (Sweden)

    Stephanie eJones


    Full Text Available Rates of psychological distress are high following diagnosis and treatment of brain tumor. There can be multiple barriers to accessing psychological support, including physical and cognitive impairments and geographical limitations. Tele-based support could provide an effective and more flexible option for delivering psychological interventions. The present study aimed to investigate the feasibility and utility of a telephone-based psychotherapy intervention for people with brain tumor. A single-case multiple-baseline design was employed with a 4-7 week baseline phase, 10-week treatment phase and 5-week maintenance phase including a booster session. Four participants with a benign or malignant brain tumor (3 males & 1 female; aged 34 to 49 years, received 10 sessions of tele-based therapy and a booster session at four weeks post-treatment. Levels of depression, anxiety, and illness cognitions were monitored on a weekly basis throughout each phase whilst measures of quality of life, stress and self-concept were administered at the start and end of each phase. Weekly measures were analysed using a combination of both visual analysis and Tau-U statistics. Of the four participants, two of them demonstrated significant gains in mental health (depression and/or anxiety and a significant decrease in their levels of helplessness (p<.05. The other two participants did not show gains in mental health or change in illness cognitions. All participants reported improvement in quality of life post-treatment. The results of the study provide preliminary support concerning the feasibility and utility of tele-based therapy for some people with brain tumor. Further research examining factors influencing the outcomes of tele-based psychological support is needed.

  16. Social license to operate: case from brazilian mining industry (United States)

    Santiago, Ana Lúcia F.; Demajorovic, Jacques; Aledo, Antonio


    The approach of the Social License to Operate (SLO) emerges as an important element in academic discussions and business practices related to extractive industries. It appears that in productive activities with great potential to produce economic, social and environmental impacts, conventional approaches based on legal compliance no longer sufficient to legitimize the actions of companies and engagement stakeholders. Studies highlight the need of mining activities receiving a SLO "issued" by companies stakeholders, including society, government, non-governmental organizations, media and communities. However, local communities appears as major stakeholders in governance arrangements, by virtue of its proximity to extractive areas and ability to affect the company's results. Stakeholders with unmet expectations can generate conflicts and risks to the company, the knowledge of these expectations and an awareness of company managers of the importance of Social License to Operate (SLO), can generate strategies and mitigating actions to prevent and or minimize possible conflicts. The concept of SLO arises in engineering extractive industry, when you need to respond to social challenges, beyond the usual environmental challenges, technological and management. According to Franks and Cohen (2012) there is a tendency of engineering sectors, sustainability, environmental, safety and especially in risk mappings, treat the technological issues in a neutral manner, separating the technological research projects of social influences. I want to contribute to the advancement of the debate on stakeholder engagement and adopting as focus on the company's relationship with the community, the aim of this study was to understand how a social project held by one of the largest mining companies in Brazil contributed to the process of SLO. This methodological procedure adopted was a qualitative, descriptive, and exploratory interviews with the communities located in rural areas of direct

  19. Suicide in Nepal: a modified psychological autopsy investigation from randomly selected police cases between 2013 and 2015. (United States)

    Hagaman, Ashley K; Khadka, S; Lohani, S; Kohrt, B


    Yearly, 600,000 people complete suicide in low- and middle-income countries, accounting for 75% of the world's burden of suicide mortality. The highest regional rates are in South and East Asia. Nepal has one of the highest suicide rates in the world; however, few investigations exploring patterns surrounding both male and female suicides exist. This study used psychological autopsies to identify common factors, precipitating events, and warning signs in a diverse sample. Randomly sampled from 302 police case reports over 24 months, psychological autopsies were conducted for 39 completed suicide cases in one urban and one rural region of Nepal. In the total police sample (n = 302), 57.0% of deaths were male. Over 40% of deaths were 25 years or younger, including 65% of rural and 50.8% of female suicide deaths. We estimate the crude urban and rural suicide rates to be 16.1 and 22.8 per 100,000, respectively. Within our psychological autopsy sample, 38.5% met criteria for depression and only 23.1% informants believed that the deceased had thoughts of self-harm or suicide before death. Important warning signs include recent geographic migration, alcohol abuse, and family history of suicide. Suicide prevention strategies in Nepal should account for the lack of awareness about suicide risk among family members and early age of suicide completion, especially in rural and female populations. Given the low rates of ideation disclosure to friends and family, educating the general public about other signs of suicide may help prevention efforts in Nepal.

  20. Making the Traffic Operations Case for Congestion Pricing: Operational Impacts of Congestion Pricing

    Energy Technology Data Exchange (ETDEWEB)

    Chin, Shih-Miao [ORNL; Hu, Patricia S [ORNL; Davidson, Diane [ORNL


    Congestion begins when an excess of vehicles on a segment of roadway at a given time, resulting in speeds that are significantly slower than normal or 'free flow' speeds. Congestion often means stop-and-go traffic. The transition occurs when vehicle density (the number of vehicles per mile in a lane) exceeds a critical level. Once traffic enters a state of congestion, recovery or time to return to a free-flow state is lengthy; and during the recovery process, delay continues to accumulate. The breakdown in speed and flow greatly impedes the efficient operation of the freeway system, resulting in economic, mobility, environmental and safety problems. Freeways are designed to function as access-controlled highways characterized by uninterrupted traffic flow so references to freeway performance relate primarily to the quality of traffic flow or traffic conditions as experienced by users of the freeway. The maximum flow or capacity of a freeway segment is reached while traffic is moving freely. As a result, freeways are most productive when they carry capacity flows at 60 mph, whereas lower speeds impose freeway delay, resulting in bottlenecks. Bottlenecks may be caused by physical disruptions, such as a reduced number of lanes, a change in grade, or an on-ramp with a short merge lane. This type of bottleneck occurs on a predictable or 'recurrent' basis at the same time of day and same day of week. Recurrent congestion totals 45% of congestion and is primarily from bottlenecks (40%) as well as inadequate signal timing (5%). Nonrecurring bottlenecks result from crashes, work zone disruptions, adverse weather conditions, and special events that create surges in demand and that account for over 55% of experienced congestion. Figure 1.1 shows that nonrecurring congestion is composed of traffic incidents (25%), severe weather (15%), work zones, (10%), and special events (5%). Between 1995 and 2005, the average percentage change in increased peak traveler

  2. Long-term variability of sleep bruxism and psychological stress in patients with jaw-muscle pain: Report of two longitudinal clinical cases. (United States)

    Muzalev, K; Visscher, C M; Koutris, M; Lobbezoo, F


    Sleep bruxism (SB) and psychological stress are commonly considered as contributing factors in the aetiology of temporomandibular disorder (TMD) pain. However, the lack of longitudinal studies and fluctuating nature of SB, psychological stress and TMD pain have led to contradictory results regarding the association between the possible aetiological factors and TMD pain. In the present study we investigated the contribution of SB and psychological stress to TMD pain in a longitudinal study of 2 clinical TMD pain cases during a 6-week study protocol. Two female volunteers with clinically diagnosed myalgia based on the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) participated in the study. Questionnaires were used to record jaw-muscle pain and psychological stress experience, and an ambulatory polysomnography technique was used to record SB intensity. Visual analysis of the data revealed that the intensity of TMD pain was not hardwired, neither with psychological stress experience nor with increased SB activity. Within the limitations of single-patient clinical cases design, our study suggested that the presence of TMD pain cannot be explained by a simple linear model which takes psychological stress or SB into account. It also seems that psychological stress was a more important predictor factor for TMD pain than SB. © 2017 John Wiley & Sons Ltd.

  3. A curative treatment option for Complex Regional Pain Syndrome (CRPS) Type I: dorsal root entry zone operation (report of two cases). (United States)

    Kanpolat, Yucel; Al-Beyati, Eyyub; Ugur, Hasan Caglar; Akpinar, Gokhan; Kahilogullari, Gokmen; Bozkurt, Melih


    Complex Regional Pain Syndrome Type I (CRPS-I) is a debated health problem concerning its pathophysiology and treatment strategies. A 12-year-old boy and a 35-year-old woman were diagnosed with CRPS-I at different times. They had previously undergone various types of interventions with no success. After one year of follow-up and observation, DREZ lesioning operation was performed. Afterwards, both cases had transient lower extremity ataxia. The first case was followed for 60 months with no recurrence and total cure. The second case was pain-free until the 6th month, when she required psychological support; she was followed for 33 months with partial satisfactory outcome. Although not a first-line option, DREZ lesioning procedure can be chosen and may be a curative option in selected cases of CRPS-I who are unresponsive to conventional therapies.

  4. Minors, Moral Psychology, and the Harm Reduction Debate: The Case of Tobacco and Nicotine. (United States)

    Kozlowski, Lynn T


    Harm reduction debates are important in health policy. Although it has been established that morality affects policy, this article proposes that perspectives from moral psychology help to explain the challenges of developing evidence-based policy on prohibition-only versus tobacco/nicotine harm reduction for minors. Protecting youth from tobacco is critical, especially since tobacco/nicotine products are legal for adults, who usually begin using when young. Although cigarettes and other combustibles are the deadliest tobacco products, other products such as smokeless tobacco and electronic cigarettes, though unsafe, are upward of 90 percent less harmful than cigarettes. Disgust at contaminating the "purity" of youth, especially "good," low-risk youth, with any tobacco/nicotine products opposes harm reduction, as does contempt for violating so-called community values and disrespecting authority. Support for harm reduction arises from anger at failing to provide reduced harm to "bad," high-risk individuals and denying them the "liberty" to decide. Fast-thinking, moral-emotional intuitions are supported by rationalizations arising from slow-thinking processes. The recognition of such moral psychological influences and the efforts to minimize their impact may help lead to amelioration and compromise. This example from tobacco control, with divided concerns for low-risk and high-risk youth, can be applied to other harm reduction versus prohibition-only policies directed at minors.

    Bayat, M; Abbasi, A J; Noorbala, A A; Mohebbi, S Z; Moharrami, M; Yekaninejad, M S


    This case-control study aimed to compare patients with temporomandibular disorders (TMD) and healthy controls in terms of oral health-related quality of life (OHRQoL) considering Graded Chronic Pain Scale (GCPS) scores, pain duration, psychological impairment and demographic characteristics. A total of 75 patients with TMD and 75 healthy controls were recruited. The short version of Oral Health Impact Profile (OHIP-14) was administered for evaluating the OHRQoL. Psychosocial impairments were assessed using the General Health Questionnaire-28 (GHQ-28). The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) axis I and II were also used for patient diagnosis and collecting GCPS scores, pain duration, age and gender. Independent-sample t tests, Pearson's chi-square tests and multiple logistic and linear regression models were applied for statistical analysis. The mean age of the patients was 34.3±12.4 years. A female-to-male ratio of 6:1 was seen in the TMD group. The prevalence and severity of the OHIP were significantly different between the TMD and control groups (66.7% vs 12.0% and 18.0 vs 9.2, respectively). According to multiple logistic regression for OHIP prevalence and multiple linear regression for OHIP severity in the TMD group, GCPS scores and pain duration, followed by psychological impairment, were the most important predictors of the OHRQoL. TMD negatively affected the OHRQoL, particularly in patients with psychological impairments. Meanwhile, age and gender did not seem to have a serious effect. Hence, promoting the quality of life of patients with TMD requires emphasis on chronic pain management and maintaining good mental health. © 2017 John Wiley & Sons A/S.

    Full Text Available In financial circles, one of the most discussed and interested topics is the forecastability of stock prices. Many of the studies aiming at determining stock market prices rest on the fact that investors make their decisions rationally based on facts and data. In this paper, we aim to investigate the behavior of individual investors in ISE based on published literature in behavioral finance area. We have found that some psychological prejudice in fact affects the behavior of individual investors. Unlike the conventional assumptions many investors make systematic mistakes and do not utilize rational answers even though it is known. Moreover, media, friends and similar environmental factors also affect the investors’ choices, and processes that turns into herd behavior creating abnormalities in the markets which in turn causes exceptionally high or low reactions

  11. Reform of statistical inference in psychology: the case of memory & cognition. (United States)

    Finch, Sue; Cumming, Geoff; Williams, Jennifer; Palmer, Lee; Griffith, Elvira; Alders, Chris; Anderson, James; Goodman, Olivia


    Geoffrey Loftus, Editor of Memory & Cognition from 1994 to 1997, strongly encouraged presentation of figures with error bars and avoidance of null hypothesis significance testing (NHST). The authors examined 696 Memory & Cognition articles published before, during, and after the Loftus editorship. Use of figures with bars increased to 47% under Loftus's editorship and then declined. Bars were rarely used for interpretation, and NHST remained almost universal. Analysis of 309 articles in other psychology journals confirmed that Loftus's influence was most evident in the articles he accepted for publication, but was otherwise limited. An e-mail survey of authors of papers accepted by Loftus revealed some support for his policy, but allegiance to traditional practices as well. Reform of psychologists' statistical practices would require more than editorial encouragement.

  13. Application of Psychological Theories in Agent-Based Modeling: The Case of the Theory of Planned Behavior. (United States)

    Scalco, Andrea; Ceschi, Andrea; Sartori, Riccardo


    It is likely that computer simulations will assume a greater role in the next future to investigate and understand reality (Rand & Rust, 2011). Particularly, agent-based models (ABMs) represent a method of investigation of social phenomena that blend the knowledge of social sciences with the advantages of virtual simulations. Within this context, the development of algorithms able to recreate the reasoning engine of autonomous virtual agents represents one of the most fragile aspects and it is indeed crucial to establish such models on well-supported psychological theoretical frameworks. For this reason, the present work discusses the application case of the theory of planned behavior (TPB; Ajzen, 1991) in the context of agent-based modeling: It is argued that this framework might be helpful more than others to develop a valid representation of human behavior in computer simulations. Accordingly, the current contribution considers issues related with the application of the model proposed by the TPB inside computer simulations and suggests potential solutions with the hope to contribute to shorten the distance between the fields of psychology and computer science.

  14. Operationally Comparable Effect Sizes for Quantifying Changes in Behavior, with Application to Meta-Analysis of Single-Case Studies (United States)

    Pustejovsky, James E.


    Single-case designs (SCDs) are a class of research methods for evaluating intervention effects by taking repeated measurements of an outcome over time on a single case, both before and after the deliberate introduction of a treatment. SCDs are used heavily in fields such as special education, school psychology, social work, and applied behavior…

  16. Rescheduling of previously cancelled surgical cases does not increase variability in operating room workload when cases are scheduled based on maximizing efficiency of use of operating room time. (United States)

    Epstein, Richard H; Dexter, Franklin


    Conceptually, cancelling a case close to the scheduled day of surgery increases variability in operating room (OR) workload (i.e., total hours of scheduled cases plus turnovers), creating managerial problems. However, in our recent study of an OR scheduling office, cancellations (slightly) reduced variability in workload among days. If a relatively low incidence of cancellations does not cause increased variability in workload, this would be a useful finding when focusing strategic OR management initiatives. However, the previous study considered only the effect on the schedule for the day the cancelled case originally was scheduled to be performed, not the future date on which the case was performed. For 90% of cancelled cases, the patient later underwent the same or a similar procedure at the studied hospital. Thus, the OR schedule at 7:00 am each day over 2 years could be used to study case rescheduling. The primary end point, calculated for each surgeon, was the difference of 2 ratios. The first ratio was the proportion of scheduled workload attributable to previously cancelled cases, among all days for which the surgeon's workload exceeded the surgeon's median workload. The second ratio was that proportion among the other days when the surgeon performed at least 1 case. Means ± SEMs were calculated by random effects analysis, stratified by surgeon. From 7:00 am the working day before surgery through the day of surgery, 9.7% ± 0.6% of scheduled OR hours and 9.7% ± 0.5% of cases were cancelled. Among cases performed, 9.5% ± 0.5% of the scheduled hours and 9.5% ± 0.5% of the cases were previously cancelled (i.e., rescheduled to a later date and then performed). Surgeons' median workloads on days with at least 1 case were 8.3 ± 0.2 hours. The percentage of scheduled workload attributable to rescheduled cases was slightly less on days when the surgeon had larger than median workloads (-0.7% ± 0.3%, P = 0.022). Rescheduled cancelled cases did not increase

  17. Resonance Frequency Breathing Biofeedback to Reduce Symptoms of Subthreshold PTSD with an Air Force Special Tactics Operator: A Case Study. (United States)

    Petta, Lorene M


    The prevalence rates of post-traumatic stress disorder (PTSD) have been estimated to be several times higher in military populations compared to the national average. Special Tactics operators are a group that is more likely to avoid seeking psychological care due to the stigma and other consequences the diagnosis may have on their military careers. There is a need for more effective and less stigmatizing interventions to treat this population. Psychophysiological methods have been proven to be efficacious in treating PTSD, yet have received less attention as an adjunctive intervention. Resonance frequency (RF) biofeedback is a form of cardiorespiratory intervention that has shown promise as an effective treatment. The current case study examined the use of RF biofeedback in combination with other physiological and evidence-based methods as part of a comprehensive treatment approach. The client showed a significant drop from his initial scores on a screening assessment by the end of treatment, and demonstrated continued progress despite a 3-month break from the therapy. This author proposed that the synergistic effects of the multi-phased treatment approach contributed to the client's progress. Furthermore, a case was made for using multiple techniques when treating subthreshold PTSD and related symptoms within a treatment resistant population.

  18. Social Psychological Origins of Conspiracy Theories: The Case of the Jewish Conspiracy Theory in Malaysia (United States)

    Swami, Viren


    Two studies examined correlates of belief in a Jewish conspiracy theory among Malays in Malaysia, a culture in which state-directed conspiracism as a means of dealing with perceived external and internal threats is widespread. In Study 1, 368 participants from Kuala Lumpur, Malaysia, completed a novel measure of belief in a Jewish conspiracy theory, along with measures of general conspiracist ideation, and anomie. Initial analysis showed that the novel scale factorially reduced to a single dimension. Further analysis showed that belief in the Jewish conspiracy theory was only significantly associated with general conspiracist ideation, but the strength of the association was weak. In Study 2, 314 participants completed the measure of belief in the Jewish conspiracy theory, along with measures of general conspiracist ideation, and ideological attitudes. Results showed that belief in the Jewish conspiracy theory was associated with anti-Israeli attitudes, modern racism directed at the Chinese, right-wing authoritarianism, and social dominance orientation. General conspiracist ideation did not emerge as a significant predictor once other variables had been accounted for. These results suggest that there may be specific cultural and social psychological forces that drive belief in the Jewish conspiracy theory within the Malaysian context. Specifically, belief in the Jewish conspiracy theory among Malaysian Malays appears to serve ideological needs and as a mask for anti-Chinese sentiment, which may in turn reaffirm their perceived ability to shape socio-political processes.

  19. Legacy of an Anatolian Sufi from a Psychological Perspective: Case of Yunus Emre

    Directory of Open Access Journals (Sweden)

    Murat Dinçer


    Full Text Available The Sufi perspective exhibited by Yunus Emre has provided an ontological comprehension that explains the meaning of existence and life. The origin of “self” or “ego” is based on the Soul that is Truth (Hakk within this ontological understanding grounded in Oneness. It gives endless meaning to people as it refers to the value of humans not in terms of their individual attributes but their divine side. The only possible way to transition from the illusory formed self to the real self, the Soul, is through the love of Truth and with a mentor or guide that has experienced this love of Truth. The relationship that is established with the mentor or guide heals relational problems and has a nature that also frees humans from their biological, relational, societal, and psychological boundaries. One’s moral sentiment based on their perception of life is oriented to purify the negative attributes that sustain the illusory self to gain virtues that will allow one to experience the real self. Yunus has indicated an understanding of existence, meaning of life, and a remedial, liberating model of relating as well as an ethical approach towards humanity in this era of narcissism.

  2. Different operative findings of cases predicted to be symptomatic discal pseudocysts after percutaneous endoscopic lumbar discectomy (United States)

    Shiboi, Ryutaro; Oshima, Yasushi; Kaneko, Takeshi; Takano, Yuichi; Inanami, Hirohiko


    Percutaneous endoscopic lumbar discectomy (PELD) is a minimally invasive treatment for lumbar disc herniation (LDH). This report focused on one of the rare complications of PELD: symptomatic postoperative discal pseudocyst (PDP). A 27-year-old male patient (case 1) presented with recurrent radiculopathy in his left leg. Twenty days previously, he had undergone PELD for left L4/5 LDH and his symptoms temporarily improved. A 14-year-old female patient (case 2) also developed recurrent pain in her left leg. Thirty days previously, she had undergone PELD for left L4/5 LDH and her symptoms disappeared. On the basis of the finding of an expandable round lesion at the evacuated sites of LDH on magnetic resonance imaging (MRI), with low intensity of T1-weighted imaging and high intensity on T2-weighted imaging, we predicted symptomatic PDP in both cases. Given the progressive leg pain in both cases, surgical treatments were adopted (case 1: microendoscopic discectomy, case 2: PELD). During the operation, we confirmed that case 1 was a simple recurrence of LDH and case 2 was symptomatic PDP. Previous studies on symptomatic PDP included cases diagnosed without operative findings. Therefore, it should be carefully considered that such cases might be a simple recurrence of LDH. PMID:28744506

  3. A safe and efficient method for intra-operative digital photography using a waterproof case. (United States)

    Tsai, Johnlong; Liao, Han-Tsung; Wang, Wen-Ke; Lam, Wee Leon; Kuo, Liang-Mou; Chen, Ruei-Feng; Chen, Chien-Tzung


    Intra-operative photography provides valuable information for photo-documentation. In order to improve quality of photographs and avoid additional contamination, we applied a sterilised waterproof case to adapt a digital camera that allowed the operating surgeon himself to obtain his own ideal images. A prospective study was designed to investigate the efficacy and safety of this technique. A total of 46 patients were enrolled in this study. The Fujifilm FinePix F30 digital camera encased in Fuji WP-FXF30 waterproof case was used in this study. Microbiological swabs were taken from the case's surface immediately after sealing the digital camera and at the end of surgery. In addition, intra-operative wound swabs were taken for correlation. The patients were followed up to record the possibility of any additional wound infections. None of the swab results on the waterproof case were positive before use. Overall, 11 patients had positive results of bacteria growth from intra-operative wound cultures. Eight of them also revealed positive microorganisms cultured from the case surface after use, in which the bacteria strains were correlated with the intra-operative wound cultures. However, no additional bacteria growth was noted from the culture of case surface. A digital camera encased in a sterilised waterproof case met the strict requirements for sterility in our series and demonstrated no added increase in infection rate. Safe use of this technique for obtaining intra-operative photographs with high image quality can be achieved. Copyright © 2011 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

  4. Using regression equations built from summary data in the psychological assessment of the individual case: extension to multiple regression. (United States)

    Crawford, John R; Garthwaite, Paul H; Denham, Annie K; Chelune, Gordon J


    Regression equations have many useful roles in psychological assessment. Moreover, there is a large reservoir of published data that could be used to build regression equations; these equations could then be employed to test a wide variety of hypotheses concerning the functioning of individual cases. This resource is currently underused because (a) not all psychologists are aware that regression equations can be built not only from raw data but also using only basic summary data for a sample, and (b) the computations involved are tedious and prone to error. In an attempt to overcome these barriers, Crawford and Garthwaite (2007) provided methods to build and apply simple linear regression models using summary statistics as data. In the present study, we extend this work to set out the steps required to build multiple regression models from sample summary statistics and the further steps required to compute the associated statistics for drawing inferences concerning an individual case. We also develop, describe, and make available a computer program that implements these methods. Although there are caveats associated with the use of the methods, these need to be balanced against pragmatic considerations and against the alternative of either entirely ignoring a pertinent data set or using it informally to provide a clinical "guesstimate." Upgraded versions of earlier programs for regression in the single case are also provided; these add the point and interval estimates of effect size developed in the present article.

  9. Chronic post-operative iris prosthesis endophthalmitis in a patient with traumatic aniridia: a case report. (United States)

    Firl, Kevin C; Montezuma, Sandra R


    Post-operative endophthalmitis is a serious complication of intraocular surgery which may present acutely or chronically. Chronic post-operative endophthalmitis is characterized by decreased visual acuity, mild pain, and low-grade uveitis several weeks or months after intraocular surgery which may be responsive to corticosteroids, but recur upon tapering. Low virulence organisms such as Propionibacterium acnes are the most common culprit organisms, and treatment most often consists of both intravitreal antibiotic injections and surgery. Aniridia is a condition defined by total or partial loss of the iris and leads to decreased visual quality marked by glare and photophobia. Treatment of complex or severe cases of traumatic aniridia in which surgical repair is difficult may consist of implantation of iris prostheses, devices designed to reduce symptoms of aniridia. Though chronic, post-operative endophthalmitis has been associated with most intraocular surgeries including intraocular lens implantation after cataract removal, it has never been described in a patient with an iris prosthesis. In this case report, we describe the case of a 49 year old, male construction worker with traumatic aniridia who experienced chronic, recurrent low-grade intraocular inflammation and irritation for months after implantation of the Ophtec 311 prosthetic iris. Symptoms and signs of inflammation improved temporarily with sub-Tenon's capsule triamcinolone injections. Ultimately after more than 2 post-operative years, the iris prosthesis was explanted, and intravitreal cultures showed P. acnes growth after 5 days. Intravitreal antibiotics treated the infection successfully. To our knowledge, this is the first reported case of chronic, post-operative endophthalmitis in a patient with an iris prosthesis. Chronic, post-operative endophthalmitis may be a difficult to identify in the context of traumatic aniridia and iris prosthesis implantation due to other potential etiologies of

  11. A fatal case of post-operative pulmonary thromboembolism with cosmetic liposuction. (United States)

    Uemura, Koichi; Kikuchi, Yousuke; Shintani-Ishida, Kaori; Nakajima, Makoto; Yoshida, Ken-ichi


    Pulmonary thromboembolism (PTE) has been regarded as rare in Japan. However, PTE has been increasingly recognised because either of increased incidence, diagnostic progress, or social recognition. Recently, 10 Japanese Medical Associations have submitted preventive guidelines for PTE in post-operative patients and the government decided to fund this, as results of the increase in cases and concern regarding medical negligence. A fatal case of PTE after liposuction is reported. A female patient was in the home toilet after two days of immobilization following day-surgery liposuction. Clinicians must be aware of appropriate methods for the prevention of post operative PTE with cosmetic surgery.

  12. Research ethics and case studies in psychology: a commentary on Taus v. Loftus. (United States)

    Cheit, Ross E


    Loftus and Guyer have been criticized for the methods they employed in investigating an anonymous case study published by Corwin and Olafson. This article examines the ethical dimensions of their investigation. Loftus and Guyer have offered three defenses for their actions. All three of those defenses lack merit. Their investigation did not constitute oral history because it failed to comport with the basic requirements of that practice. Their investigation did not constitute ethical journalism because of the unjustified use of anonymous sources and the clear violation of basic fairness. Their investigation did not constitute justified medical research because of a failure to analyze or weigh the harms against the benefits. Their methods also violated ethical principles for psychologists, including the rule against activities that could reasonably be expected to impair the psychologist's objectivity. This case demonstrates that there is no ethical way to investigate a clinical case, without the patient's approval, that is both comprehensive enough to provide strong scholarship and yet respectful enough of privacy and medical confidentiality to honor important professional norms. © The Author(s) 2014.

  13. Association between self-perceived psychological stress and transitory ischaemic attack and minor stroke: A case-control study. (United States)

    Ramírez-Moreno, J M; Muñoz Vega, P; Espada, S; Bartolomé Alberca, S; Aguirre, J; Peral, D


    Stroke has a complex aetiopathogenesis influenced by numerous risk factors. There is growing interest in the study of the pathophysiological changes associated with stress and their potential relationship with cerebrovascular disease. The purpose of this paper is to assess the strength of association between exposure to stress and stroke. We conducted a case-control study (1:1) to compare exposure to stress in a group of patients with a history of a first transient ischaemic attack (TIA) or minor stroke and in a control group. Participants were asked a subjective question about their perception of stress in the previous months and completed the standardised Effort-Reward Imbalance (ERI) questionnaire. Logistic regression models were used for data analysis. The study included data on 50 cases and 50 controls. There were no significant differences in demographic variables and economic, social, and employment status between cases and controls. Fifty percent of the cases reported moderate to severe stress, compared to 30% of controls (OR: 2.33; 95% CI: 1.02-5.30; P=.041). ERI questionnaire results found that greater effort at work (OR: 1.48; 95% CI: 1.19-1.83) and greater commitment is associated with stroke (OR: 1.34; 95% CI: 1.17-1.54), while higher reward constitutes a protective factor against the disease (OR: 0.71; 95% CI: 0.61-0.82). There is a strong association between self-perceived psychological stress and TIA. The imbalance between effort and reward at work is also clearly related to TIA.

    Directory of Open Access Journals (Sweden)

    Bilender P. Allahverdiev


    Full Text Available We consider the maximal dissipative second-order difference (or discrete Sturm-Liouville operators acting in the Hilbert space ℓ2(ℤ (ℤ:={0,±1,±2,…}, that is, the extensions of a minimal symmetric operator with defect index (2,2 (in the Weyl-Hamburger limit-circle cases at ±∞. We investigate two classes of maximal dissipative operators with separated boundary conditions, called “dissipative at −∞” and “dissipative at ∞.” In each case, we construct a self-adjoint dilation of the maximal dissipative operator and its incoming and outgoing spectral representations, which make it possible to determine the scattering matrix of the dilation. We also establish a functional model of the maximal dissipative operator and determine its characteristic function through the Titchmarsh-Weyl function of the self-adjoint operator. We prove the completeness of the system of eigenvectors and associated vectors of the maximal dissipative operators.

  16. The influence of psychological factors on pre-operative levels of pain intensity, disability and health-related quality of life in lumbar spinal fusion surgery patients. (United States)

    Abbott, Allan D; Tyni-Lenné, Raija; Hedlund, Rune


    To assess the extent to which perceived pain and psychological factors explain levels of disability and health-related quality of life (HRQOL) in patients scheduled for lumbar fusion surgery, and to test the hypothesis that relationships between pain intensity, mental health, fear of movement/(re)injury, disability and HRQOL are mediated by cognitive beliefs and appraisals. Cross-sectional, correlation study. Orthopaedic outpatient setting in a tertiary hospital. One hundred and seven chronic back pain patients scheduled for lumbar fusion surgery. Visual analogue scale for pain intensity, Short Form 36 mental health subscale, Tampa Scale for Kinesiophobia, Back Beliefs Questionnaire, Self-efficacy Scale, Coping Strategy Questionnaire, Oswestry Disability Index and European Quality of Life Questionnaire. The group effect of multiple mediators significantly influenced the relationships between pain intensity and mental health, fear of movement/(re)injury, functional disability and HRQOL. Pain catastrophising significantly mediated the relationship between pain intensity and mental health, control over pain significantly mediated the relationship between mental health and functional disability, self-efficacy and pain outcome expectancy significantly mediated the relationship between mental health and HRQOL, and self-efficacy also significantly mediated the relationship between pain intensity, fear of movement/(re)jury and functional disability. The model explained 28, 30, 52 and 42% of the variation in mental health, fear of movement/(re)injury, functional disability and HRQOL, respectively. This study highlights the strong influence and mediation roles of psychological factors on pain, mental health, fear of movement/(re)injury, disability and HRQOL in patients scheduled for lumber fusion. Future research should focus on screening as well as pre- and post-operative interventions based on these psychological factors for the potential improvement of lumber fusion

  17. Psychological resilience and postdeployment social support protect against traumatic stress and depressive symptoms in soldiers returning from Operations Enduring Freedom and Iraqi Freedom. (United States)

    Pietrzak, Robert H; Johnson, Douglas C; Goldstein, Marc B; Malley, James C; Southwick, Steven M


    A number of studies have examined the prevalence and correlates of posttraumatic stress disorder (PTSD), depression, and related psychiatric conditions in soldiers returning from Operations Enduring Freedom and Iraqi Freedom (OEF/OIF), but none have examined whether factors such as psychological resilience and social support may protect against these conditions in this population. A total of 272 predominantly older reserve/National Guard OEF/OIF veterans completed a mail survey assessing traumatic stress and depressive symptoms, resilience, and social support. Resilience scores in the full sample were comparable to those observed in civilian outpatient primary-care patients. Respondents with PTSD, however, scored significantly lower on this measure and on measures of unit support and postdeployment social support. A hierarchical regression analysis in the full sample suggested that resilience (specifically, increased personal control and positive acceptance of change) and postdeployment social support were negatively associated with traumatic stress and depressive symptoms, even after adjusting for demographic characteristics and combat exposure. These results suggest that interventions to bolster psychological resilience and postdeployment social support may help reduce the severity of traumatic stress and depressive symptoms in OEF/OIF veterans.

  1. Is semen loss syndrome a psychological or physical illness? A case for conflict of interest. (United States)

    Kattimani, Shivanand; Menon, Vikas; Shrivastava, Manohar Kant


    Young men presenting with sexual problems arising out of non-contact like semen loss syndrome are common in the Indian subcontinent. They usually present with depressive, anxiety symptoms, and non-specific somatic complaints. This has no medical explanation and is currently conceptualized as a culture bound neurotic disorder in the International Classification of Diseases-10 (ICD-10), clinical descriptions, and diagnostic guidelines. In this report, we present the case of a young male who developed delusions following concerns about semen loss. Conflicting explanations about his illness between traditional and allopathic practitioners led to problems in management. The importance of creating awareness among traditional practitioners regarding contemporary allopathic models of illness is stressed. Management strategies employed should reflect this shared understanding.

    Physical illness is linked with an increased risk of suicide; however, evidence from China is limited. To assess the influence of physical illness on risk of suicide among rural residents of China, and to examine the differences in the characteristics of people completing suicide with physical illness from those without physical illness. In all, 200 suicide cases and 200 control subjects, 1:1 pair-matched on sex and age, were included from 25 townships of three randomly selected counties in Shandong Province, China. One informant for each suicide or control subject was interviewed to collect data on the physical health condition and psychological and sociodemographic status. The prevalence of physical illness in suicide cases (63.0%) was significantly higher than that in paired controls (41.0%; χ² = 19.39, p suicide cases without physical illness, people who were physically ill and completed suicide were generally older, less educated, had lower family income, and reported a mental disorder less often. Physical illness denoted a significant risk factor for suicide with an associated odds ratio of 3.23 (95% CI: 1.85-5.62) after adjusted for important covariates. The elevated risk of suicide increased progressively with the number of comorbid illnesses. Cancer, stroke, and a group of illnesses comprising dementia, hemiplegia, and encephalatrophy had a particularly strong effect among the commonly reported diagnoses in this study population. Physical illness is an important risk factor for suicide in rural residents of China. Efforts for suicide prevention are needed and should be integrated with national strategies of health care in rural China.

  3. Post-operative Aspergillus mediastinitis in a man who was immunocompetent: a case report

    Directory of Open Access Journals (Sweden)

    Orfanos Stylianos


    Full Text Available Abstract Introduction Aspergillus spp. infections mainly affect patients who are immunocompromised, and are extremely rare in immunocompetent individuals. Case presentation Aspergillus post-operative mediastinitis is considered to be a devastating infection, usually affecting patients undergoing cardiothoracic surgery with specific predisposing factors. We describe the case of an immunocompetent 68-year-old Caucasian man with severe chronic thromboembolic pulmonary hypertension, who underwent pulmonary thromboendarterectomy and developed post-operative mediastinitis due to Aspergillus flavus. The environmental control did not reveal the source of A. flavus infection and, despite combined antifungal therapy, our patient died as a result of septic shock and multiple organ failure. Conclusion Aspergillus mediastinitis mainly affects patients after cardiosurgery operations with predisposing factors, and it is unusual in patients who are immunocompetent. The identification of the Aspergillus spp. source is often difficult, and there are no guidelines for the administration of pre-emptive therapy in this population of at-risk patients.

  4. Classification of Household Appliance Operation Cycles: A Case-Study Approach

    Directory of Open Access Journals (Sweden)

    Zeyu Wang


    Full Text Available In recent years, a new generation of power grid system, referred to as the Smart Grid, with an aim of managing electricity demand in a sustainable, reliable, and economical manner has emerged. With greater knowledge of operational characteristics of individual appliances, necessary automation control strategies can be developed in the Smart Grid to operate appliances in an efficient manner. This paper provides a way of classifying different operational cycles of a household appliance by introducing an unsupervised learning algorithm called k-means clustering. An intrinsic method known as silhouette coefficient was used to measure the classification quality. An identification process is also discussed in this paper to help users identify the operation mode each types of operation cycle stands for. A case study using a typical household refrigerator is presented to validate the proposed method. Results show that the proposed the classification and identification method can partition and identify different operation cycles adequately. Classification of operation cycles for such appliances is beneficial for Smart Grid as it provides a clear and convincing understanding of the operation modes for effective power management.

  5. Symptoms of psychological distress and post-traumatic stress disorder in United States Air Force "drone" operators. (United States)

    Chappelle, Wayne L; McDonald, Kent D; Prince, Lillian; Goodman, Tanya; Ray-Sannerud, Bobbie N; Thompson, William


    The goal of this study is to repeat a survey administered in 2010 to assess for changes in mental health among United States Air Force aircrew operating Predator/Reaper remotely piloted aircraft, also commonly referred to as "drones." Participants were assessed for self-reported sources of occupational stress, levels of clinical distress using the Outcome Questionnaire-45.2, and symptoms of post-traumatic stress disorder (PTSD) using the PTSD Checklist-Military Version. A total of 1,094 aircrew responded to the web-based survey composed of the commercially available standardized instruments mentioned above. The survey also contained nonstandardized items asking participants to report the main sources of their occupational stress, as well as questions addressing demographics and work-related characteristics. The estimated response rate to the survey was 49%. Study results reveal the most problematic self-reported stressors are operational: low manning, extra duties/administrative tasks, rotating shift work, and long hours. The results also reveal 10.72% of operators self-reported experiencing high levels of distress and 1.57% reported high levels of PTSD symptomology. The results are lower than findings from the 2010 survey and from soldiers returning from Iraq and Afghanistan. Implications of the study and recommendations for United States Air Force line leadership and mental health providers are discussed.

  7. Preparing Safety Cases for Operating Outside Prescriptive Fatigue Risk Management Regulations. (United States)

    Gander, Philippa; Mangie, Jim; Wu, Lora; van den Berg, Margo; Signal, Leigh; Phillips, Adrienne


    Transport operators seeking to operate outside prescriptive fatigue management regulations are typically required to present a safety case justifying how they will manage the associated risk. This paper details a method for constructing a successful safety case. The method includes four elements: 1) scope (prescriptive rules and operations affected); 2) risk assessment; 3) risk mitigation strategies; and 4) monitoring ongoing risk. A successful safety case illustrates this method. It enables landing pilots in 3-pilot crews to choose the second or third in-flight rest break, rather than the regulatory requirement to take the third break. Scope was defined using a month of scheduled flights that would be covered (N = 4151). These were analyzed in the risk assessment using existing literature on factors affecting fatigue to estimate the maximum time awake at top of descent and sleep opportunities in each break. Additionally, limited data collected before the new regulations showed that pilots flying at landing chose the third break on only 6% of flights. A prospective survey comparing subjective reports (N = 280) of sleep in the second vs. third break and fatigue and sleepiness ratings at top of descent confirmed that the third break is not consistently superior. The safety case also summarized established systems for fatigue monitoring, risk assessment and hazard identification, and multiple fatigue mitigation strategies that are in place. Other successful safety cases have used this method. The evidence required depends on the expected level of risk and should evolve as experience with fatigue risk management systems builds.Gander P, Mangie J, Wu L, van den Berg M, Signal L, Phillips A.

  8. Expert System Models for Forecasting Forklifts Engagement in a Warehouse Loading Operation: A Case Study

    Directory of Open Access Journals (Sweden)

    Dejan Mirčetić


    Full Text Available The paper focuses on the problem of forklifts engagement in warehouse loading operations. Two expert system (ES models are created using several machine learning (ML models. Models try to mimic expert decisions while determining the forklifts engagement in the loading operation. Different ML models are evaluated and adaptive neuro fuzzy inference system (ANFIS and classification and regression trees (CART are chosen as the ones which have shown best results for the research purpose. As a case study, a central warehouse of a beverage company was used. In a beverage distribution chain, the proper engagement of forklifts in a loading operation is crucial for maintaining the defined customer service level. The created ES models represent a new approach for the rationalization of the forklifts usage, particularly for solving the problem of the forklifts engagement incargo loading. They are simple, easy to understand, reliable, and practically applicable tool for deciding on the engagement of the forklifts in a loading operation.

  9. Predicting the Emergence of Community Psychology and Community Development in 91 Countries with Brief Case Studies of Chile and Ghana. (United States)

    Hanitio, Felicia; Perkins, Douglas D


    Using a mixed-method analysis, we propose and test a framework for predicting the international development of community psychology (CP) and community development (CD) as two examples of applied community-based research (CBR) disciplines aiming to link local knowledge generation with social change. Multiple regressions on an international sample of 91 countries were used to determine the relative influences of preexisting grassroots activism, population size, social and economic development, and civil liberties on estimates of the current strength of CP and CD based on Internet search and review of training courses and programs, published articles and journals, and professional organizations and conferences in these countries. Our results provide support for the proposed model and suggest that grassroots activism positively accounts for the development of CP and CD, above and beyond the influences of the other predictors. Brief qualitative case-study analyses of Chile (high CP, low CD) and Ghana (high CD, low CP) explore the limitations of our quantitative model and the importance of considering other historical, sociopolitical, cultural, and geographic factors for explaining the development of CP, CD, and other applied community studies. © Society for Community Research and Action 2017.

  10. Using Design Thinking to Improve Psychological Interventions: The Case of the Growth Mindset During the Transition to High School (United States)

    There are many promising psychological interventions on the horizon, but there is no clear methodology for preparing them to be scaled up. Drawing on design thinking, the present research formalizes a methodology for redesigning and tailoring initial interventions. We test the methodology using the case of fixed versus growth mindsets during the transition to high school. Qualitative inquiry and rapid, iterative, randomized “A/B” experiments were conducted with ~3,000 participants to inform intervention revisions for this population. Next, two experimental evaluations showed that the revised growth mindset intervention was an improvement over previous versions in terms of short-term proxy outcomes (Study 1, N=7,501), and it improved 9th grade core-course GPA and reduced D/F GPAs for lower achieving students when delivered via the Internet under routine conditions with ~95% of students at 10 schools (Study 2, N=3,676). Although the intervention could still be improved even further, the current research provides a model for how to improve and scale interventions that begin to address pressing educational problems. It also provides insight into how to teach a growth mindset more effectively. PMID:27524832

  11. A positive psychology to cope with radicalisation and terrorism? A case study of the speech by Barack Obama at Cairo

    Directory of Open Access Journals (Sweden)

    Manuel Moyano


    Full Text Available Since the September 11 terrorist attacks, coping with radicalisation and jihadist terrorism has been at the forefront of the domestic and foreign policy agendas in Western societies. During this time, the influence that political leaders can exert in their interaction with institutions, citizens, and terrorist organizations has been demonstrated. We present a case study of the speech by Barak Obama on June 4, 2009 at the University of Cairo (“A New Beginning”. Its content and internal structure is analysed using the classification of virtues and strengths defined by Peterson and Seligman (2004 as a theoretical and conceptual reference within the framework of positive psychology. This speech marked a turning point in the relationship between the USA and the Arab-Muslim world and could be considered to be a genuine exercise in positive communication. Its implications are yet to be determined, because it continues to exert an influence on the Obama administration’s domestic and foreign policy. In a globalized and networking world in which risks and adversities require innovative responses, more than ever we suggest that social communication capable of promoting virtues and strengths associated with optimism, hope, confidence, strength, or vitality is needed more than ever.

  13. The Effect of Instructional Supervision by an Operating Room Assistant on First-Case Starts. (United States)

    Pan, Xiaohua; Zhang, Jun; Dai, Chen; Si, Yibing


    Delays in starting first cases of the day are a common topic associated with high economic costs. This study aimed to determine if an operating room (OR) assistant using an instructional supervision program could reduce the tardiness of first-case starts. A prospective study was conducted. Data from four ORs were used to compare the effectiveness of an instructional intervention to reduce delays in starting first cases of the day. The first cases in two ORs received instructional supervision by an OR. The primary endpoint was the percentage of first cases that started on time. Other endpoints were the percentage of the team work score of OR staff and the percentage of patient satisfaction score. Over 48 weeks, the effect of instructional supervision was evaluated in 960 first-case starts. In the instructional supervision group (n = 480), the percentage of first cases that started on time increased significantly (92.1% vs 71.7%; P Instructional supervision by an OR assistant can make a potential improvement in our on-time first-case starts per day.

  14. First-Case Operating Room Delays: Patterns Across Urban Hospitals of a Single Health Care System

    Directory of Open Access Journals (Sweden)

    Callie M. Cox Bauer


    Full Text Available Purpose: Operating room delays decrease health care system efficiency and increase costs. To improve operating room efficiency in our system, we retrospectively investigated delay frequencies, causes and costs. Methods: We studied all first-of-the-day nonemergent surgical cases performed at three high-volume urban hospitals of a large health system from July 2012 to November 2013. Times for patient flow from arrival to procedure start and documented reasons for delay were obtained from electronic medical records. Delay was defined as patient placement in the operating room later than scheduled surgery time. Effects of patient characteristics, late patient arrival to the hospital, number of planned procedures, years of surgeon experience, service department and hospital facility on odds of delay were examined using logistic regression. Results: Of 5,598 cases examined, 88% were delayed. Patients arrived late to the hospital (surgery in 65% of first cases. Mean time from arrival to scheduled surgery and in-room placement was 104.6 and 127.4 minutes, respectively. Mean delay time was 28.2 minutes. Nearly 60% of delayed cases had no documented reason for delay. For cases with documentation, causes included the physician (52%, anesthesia (15%, patient (13%, staff (9%, other sources (6% and facility (5%. Regression analysis revealed age, late arrival, department and facility as significant predictors of delay. Estimated delay costs, based on published figures and representing lost revenue, were $519,388. Conclusions: To improve operating room efficiency, multidisciplinary strategies are needed for increasing patient adherence to recommended arrival times, documentation of delay by medical staff and consistency in workflow patterns among facilities and departments.

  18. The physical and psychological impact of using a computer-based environmental control system: a case study. (United States)

    Squires, Luke A; Rush, Frank; Hopkinson, Andrew; Val, Morrison


    To evaluate a new computer-based environmental control system, Subvenio, in terms of its physical and psychological impact in a single case study of a 46-year-old woman with a severe physical disability, tetraplegia. Expectations of the system and factors relating to successful Subvenio use were also sought. A longitudinal questionnaire measured function (BI; FAI), mental health and wellbeing (GHQ-12; WHO-5) 6 weeks before, and 10 and 26 weeks after Subvenio installation. Expectations and Subvenio experience were explored through open-ended questions. Daily assessment of mood and Subvenio use was also recorded for a one-week period in-between each time point. Data obtained did not suggest changes in global functioning or emotional wellbeing whilst activity increased for specific everyday tasks such as turning on the lights and television. Qualitatively, other benefits of Subvenio were identified such as independence and less reliance on carers. Computer-based assistive technology (AT) points to qualitative benefits for this individual, encouraging further research with larger samples. Various factors facilitated Subvenio use and the benefits derived from it, including device factors and personal characteristics (e.g. pain). Healthcare and service providers should communicate with AT/environmental control system users about these factors before and during provision to maximise benefits and limit AT abandonment. Implications for Rehabilitation One implication from this study is that AT development should focus on the factors influencing successful AT use. In this study notably, optimism, expectations of AT, pain, symptom changes and service delivery are all highlighted. Communication between AT service providers and AT users is encouraged to prevent unrealistic expectations of AT equipment, and such communication should continue throughout AT use to ensure the equipment is still meeting the user needs.

  19. Neurocognitive and Psychological Outcomes in Adults With Dextro-Transposition of the Great Arteries Corrected by the Arterial Switch Operation. (United States)

    Kasmi, Leïla; Calderon, Johanna; Montreuil, Michèle; Geronikola, Nikoletta; Lambert, Virginie; Belli, Emrè; Bonnet, Damien; Kalfa, David


    Neurodevelopmental impairments have frequently been described in children and adolescents with dextro-transposition of the great arteries (d-TGA). The arterial switch operation (ASO) to correct d-TGA has been used for more than 30 years, and more than 90% of these patients now reach adulthood. However, very little is known about their long-term functional outcomes. The present study investigated neurocognitive outcomes and the prevalence of psychiatric disorders in adults with d-TGA corrected by ASO. Neurocognitive functioning was comprehensively assessed (general intellectual functioning, language, attention, visual-spatial skills, executive functions, memory) in 67 adults (59.7% men) with d-TGA (aged 22.9 ± 3.4 years) and in 43 healthy individuals. The prevalence of psychiatric disorders, including depression and anxiety, was evaluated using a structured diagnostic interview. We also analyzed patient- and operative-related risk factors associated with outcomes. Compared with the general population and the control group, adults with d-TGA displayed reduced performance in tasks assessing attention, visual-spatial skills, executive functions, and memory (all p < 0.05). Compared with controls, patients had also a higher lifetime prevalence of depression (43% vs 19%, p = 0.008) and anxiety disorders (54% vs 33%, p = 0.025). Predictors of long-term outcomes included gender and parental socioeconomic and educational status (all p < 0.05). Adults who have undergone a neonatal ASO to correct d-TGA have an increased risk of cognitive deficits and psychiatric disorders. Evaluation of long-term neuropsychological and psychosocial outcomes in early adulthood is a crucial step to anticipate for adapted treatment strategies in adults with congenital heart disease.

  20. Menometrorrhagia in magnetic resonance imaging operators with copper intrauterine contraceptive devices (IUDS): a case report. (United States)

    Gobba, Fabriziomaria; Bianchi, Nadia; Verga, Paolo; Contessa, Gian Marco; Rossi, Paolo


    The paper describes the cases of 3 female health operators with implanted copper IUDs, developing menometrorrhagia some months after an increase of the working time in a Magnetic Resonance Imaging (MRI) Unit (1.5 T), that progressively disappeared when the previous organization, involving discontinuous work shifts at MRI, was re-established. No known factors possibly related to menometrorrhagia were evidenced in the 3 operators, supporting the hypothesis of a role of the exposure to the electromagnetic fields (EMF) induced by the MRI system in symptoms induction. The possible mechanism remains unsettled, but menometrorrhagia might be triggered by a phlogistic stimulus caused by EMF, possibly the low-frequency currents induced in the wires of the IUD during the movements of the operator inside the static magnetic field generated by the MRI permanent magnet. Until now, the problem of possible interactions between copper IUDs and EMF induced by MRI has been considered in patients undergoing imaging, but the possible risk in MRI Units operators has been largely neglected. To our knowledge, the occurrence of menometrorrhagia is not routinely checked in health surveillance of MRI operators, so these symptoms can pass unnoticed, especially if they are transitory. Therefore, underreporting is rather possible. The cases described here support the need for further research on this topic, especially considering the progressive diffusion of more powerful MRI scanners (3 T and more), and of the interventional magnetic resonance imaging, both potentially involving higher EMF exposures, and a large number of MRI female operators, possibly using IUDs. The possibility that MRI operators with implanted metallic IUDs can be included in the group of "workers at particular risk" according to the EU Directive 2004/40/EC should be considered.

  4. Wandering spleen associated with omphalocele in a neonate: An unusual case with non-operative management

    Directory of Open Access Journals (Sweden)

    Daisuke Masui


    Full Text Available Wandering spleen with a history of omphalocele is extremely rare. We encountered a male baby with wandering spleen associated with omphalocele. This case of wandering spleen in a neonate was diagnosed by ultrasound and computed tomography scans after surgery for omphalocele. Our case was able to be managed non-operatively due to the lack of any findings suggesting torsion of the spleen and its asymptomatic status. We herein report the clinical presentation as well as the treatment options regarding wandering spleen associated with omphalocele.

  5. Lumbar radiculopathy due to unilateral facet hypertrophy following lumbar disc hernia operation: a case report. (United States)

    Kökeş, Fatih; Günaydin, Ahmet; Aciduman, Ahmet; Kalan, Mehmet; Koçak, Halit


    To present a radiculopathy case due to unilateral facet hypertrophy developing three years after a lumbar disc hernia operation. A fifty two-year-old female patient, who had been operated on for a left L5-S1 herniated lumbar disc three years ago, was hospitalized and re-operated with a diagnosis of unilateral facet hypertrophy. She had complaints of left leg pain and walking restrictions for the last six months. Left Straight Leg Raising test was positive at 40 degrees , left ankle dorsiflexion muscle strength was 4/5, left Extensor Hallucis Longus muscle strength was 3/5, and left Achilles reflex was hypoactive. Lumbar spinal Magnetic Resonance Imaging revealed left L5-S1 facet hypertrophy. Lumbar radiculopathy due to lumbar facet hypertrophy is a well-known neurological condition. Radicular pain develops during the late postoperative period following lumbar disc hernia operations that are often related to recurrent disc herniation or to formation of post-operative scar tissue. In addition, it can be speculated that unilateral facet hypertrophy, which may develop after a disc hernia operation, might also be one of the causes of radiculopathy.

  6. The Bloch wave operator: generalizations and applications: Part I. The time-independent case

    Energy Technology Data Exchange (ETDEWEB)

    Killingbeck, John P [Mathematics Department, University of Hull, Hull HU6 7RX (United Kingdom); Jolicard, Georges [Observatoire de Besancon (UMR-CNRS 6091), Universite de Franche-Comte, 41 bis, Avenue de l' Observatoire, 25000 Besancon (France)


    This is part 1 of a two-part review on wave operator theory and methods. The basic theory of the time-independent wave operator is presented in terms of partitioned matrix theory for the benefit of general readers, with a discussion of the links between the matrix and projection operator approaches. The matrix approach is shown to lead to simple derivations of the wave operators and effective Hamiltonians of Loewdin, Bloch, Des Cloizeaux and Kato as well as to some associated variational forms. The principal approach used throughout stresses the solution of the nonlinear equation for the reduced wave operator, leading to the construction of the effective Hamiltonians of Bloch and of Des Cloizeaux. Several mathematical techniques which are useful in implementing this approach are explained, some of them being relatively little known in the area of wave operator calculations. The theoretical discussion is accompanied by several specimen numerical calculations which apply the described techniques to a selection of test matrices taken from the previous literature on wave operator methods. The main emphasis throughout is on the use of numerical methods which use iterative or perturbation algorithms, with simple Pade approximant methods being found sufficient to deal with most of the cases of divergence which are encountered. The use of damping factors and relaxation parameters is found to be effective in stabilizing calculations which use the energy-dependent effective Hamiltonian of Loewdin. In general the computations suggest that the numerical applications of the nonlinear equation for the reduced wave operator are best carried out with the equation split into a pair of equations in which the Bloch effective Hamiltonian appears as a separate entity. The presentation of the theoretical and computational details throughout is accompanied by references to and discussion of many works which have used wave operator methods in physics, chemistry and engineering.

    Drake, Frederick Thurston; Horvath, Karen D; Goldin, Adam B; Gow, Kenneth W


    The chief resident (CR) year is a pivotal experience in surgical training. Changes in case volume and diversity may impact the educational quality of this important year. To evaluate changes in operative experience for general surgery CRs. Review of Accreditation Council for Graduate Medical Education case logs from 1989-1990 through 2011-2012 divided into 5 periods. Graduates in period 3 were the last to train with unrestricted work hours; those in period 4 were part of a transition period and trained under both systems; and those in period 5 trained fully under the 80-hour work week. Diversity of cases was assessed based on Accreditation Council for Graduate Medical Education defined categories. Total cases and defined categories were evaluated for changes over time. The average total CR case numbers have fallen (271 in period 1 vs 242 in period 5, P surgery training may be jeopardized by reduced case diversity. Chief resident cases are crucial in surgical training and educators should consider these findings as surgical training evolves.

    Happell, Nadine; Miksell, Steve; Carlisle, Candace


    A major barrier in taking expert systems from prototype to operational status involves instilling end user confidence in the operational system. The software of different life cycle models is examined and the advantages and disadvantages of each when applied to expert system development are explored. The Fault Isolation Expert System for Tracking and data relay satellite system Applications (FIESTA) is presented as a case study of development of an expert system. The end user confidence necessary for operational use of this system is accentuated by the fact that it will handle real-time data in a secure environment, allowing little tolerance for errors. How FIESTA is dealing with transition problems as it moves from an off-line standalone prototype to an on-line real-time system is discussed.

    A major barrier in taking expert systems from prototype to operational status involves instilling end user confidence in the operational system. The software of different life cycle models is examined and the advantages and disadvantages of each when applied to expert system development are explored. The Fault Isolation Expert System for Tracking and data relay satellite system Applications (FIESTA) is presented as a case study of development of an expert system. The end user confidence necessary for operational use of this system is accentuated by the fact that it will handle real-time data in a secure environment, allowing little tolerance for errors. How FIESTA is dealing with transition problems as it moves from an off-line standalone prototype to an on-line real-time system is discussed.

  12. Communicating for Climate Change Adaptation: Lessons from a Case Study with Nature-Based Tour Operators (United States)

    Timm, K.; Sparrow, E. B.; Pettit, E. C.; Trainor, S. F.; Taylor, K.


    Increasing temperatures are projected to have a positive effect on the length of Alaska's tourism season, but the natural attractions that tourism relies on, such as glaciers, wildlife, fish, or other natural resources, may change. In order to continue to derive benefits from these resources, nature-based tour operators may have to adapt to these changes, and communication is an essential, but poorly understood, component of the climate change adaptation process. The goal of this study was to determine how to provide useful climate change information to nature-based tour operators by answering the following questions: 1. What environmental changes do nature-based tour operators perceive? 2. How are nature-based tour operators responding to climate and environmental change? 3. What climate change information do nature-based tour operators need? To answer these questions, twenty-four nature-based tour operators representing 20 different small and medium sized businesses in Juneau, Alaska were interviewed. The results show that many of Juneau's nature-based tour operators are observing, responding to, and in some cases, actively planning for further changes in the environment. The types of responses tended to vary depending on the participants' certainty in climate change and the perceived risks to their organization. Using these two factors, this study proposes a framework to classify climate change responses for the purpose of generating meaningful information and communication processes that promote adaptation and build adaptive capacity. During the course of the study, several other valuable lessons were learned about communicating about adaptation. The results of this study demonstrate that science communication research has an important place in the practice of promoting and fostering climate change adaptation. While the focus of this study was tour operators, the lessons learned may be valuable to other organizations striving to engage unique groups in climate

    Chong-de SU


    Full Text Available Objective  To explore the preoperative evaluation and operative indications for intractable secondary epilepsy after craniocerebral operation, and to summarize the experiences of second craniotomy for epileptogenic zone resection, so as to improve the treatment efficacy of epilepsy secondary to neurosurgery. Methods  From Jan. 2005 to May 2012, a total of 25 patients with secondary epilepsy after craniocerebral operation were evaluated carefully by assessment of medical history and pre-operative video electroencephalography (VEEG examination. Electroencephalography or implantation of subdural electrodes for localizing the epileptogenic zone was conducted in each patient during and after epileptic attack. The epileptogenic zone was confirmed by electroencephalography, MRI and CT scanning before the second operation. The operation was performed along the original incision for complete exposure of the brain scar zone. After localization of the position and range of spike waves with cortical electrodes, the brain scar and epileptogenic focus were removed microscopically. After resection, re-examination was conducted with the cortical electrodes till brain wave rhythm became normal. Results  No death or severe complication was found in the 25 patients. During a follow-up period of 6 months to 7 years, 18 patients were seizure free (Engel's class Ⅰ, 5 patients were Engel's class Ⅱ, and 2 patients were Engel's class Ⅲ. No post-operative attack was found in 18 cases (72%, and 9 of them had their drugs withdrawn. Conclusion  The medication effect of secondary epilepsy after craniocerebral operation is far from perfect, and second craniotomy could attain satisfactory results.

  14. Estimating truck operating costs for domestic trips – case studies from Greece

    Directory of Open Access Journals (Sweden)

    Sdoukopoulos Eleftherios


    Full Text Available The transport sector represents a vital component of national economies and has significant impacts on productivity and social welfare. In 2012, the transport sector in Europe was estimated to account for 3.7% of the European Gross Domestic Product (GDP and 5.1% for employment. Road transport proves to be the predominant mode for moving goods within Europe holding a share of approximately 45.8% in 2012 (in ton-kms. In Greece, the share of road freight transport is significantly higher (98% indicating the importance of this sector for the Greek economy. To this end and considering the existing needs of road freight transport operators in Greece, the objective of this research is to establish an analytical and documented basis for estimating the operating cost of a truck on specific urban or national freight transport routes. To achieve this goal, an extended literature review has been conducted resulting in the identification of the main components comprising the total truck operating cost, which were then updated and validated through a series of personal interviews with selected road freight transport professionals. An excel-based application tool was also developed in order to facilitate operating cost estimates for different cases, through selection of the proper values of the relevant parameters. The resulting tool was used to analyse four test cases, which demonstrate the tool’s usability and applicability. Results from this analysis have been also validated by industry experts and they reflect real-world transport scenarios.

  15. Effective strategies in improving operating room case delays and cancellations at an academic medical center. (United States)

    Kaye, Alan David; McDowell, Joseph L; Diaz, James H; Buras, Jay A; Young, Amy E; Urman, Richard D


    Traditionally, the operating room (OR) in an academic medical center has faced numerous challenges to effective clinical productivity, including additional missions of teaching and research. Level 1 trauma poses more challenges related to the need for additional specialized personnel in anesthesia, surgery, and nursing. The present investigation explores lessons learned in efficiency, teamwork, and data evaluation at a level 1 academic teaching facility. The months of July 2012, July 2013, and July 2014 were selected for this study. Multiple strategies were implemented through the Operating Room Committee during this time in an effort to reduce the number of OR delays and cancellations. Case cancellations decreased significantly over the three-year period, while delays remained relatively stable. In July 2012, 15.0% of cases were cancelled and 10.2% were delayed. Cancellations decreased to 6.3% in 2013 and to 5.9% in 2014. The total number of cases completed per month increased each year throughout the study, from 577 in 2012 to 649 in 2013 to 842 in 2014. These results are remarkable in comparison to the greater-than 20% cancellation rate recorded in 2005 when the current OR leadership team first assessed OR efficiency. An increase in the number of cases completed per month likely can be attributed to a reduction in the number of case cancellations. Increased efficiency allows for more operations to be performed, leading to increased profitability and an increased ability of hospitals to continue caring for patients. We advocate the implementation of a comprehensive multidisciplinary strategy for sustained improvement in OR efficiency and utilization.

  18. Vision-related quality of life and psychological status in Chinese women with Sjogren's syndrome dry eye: a case-control study. (United States)

    Zhang, Yuqiu; Lin, Tong; Jiang, Alice; Zhao, Naiqing; Gong, Lan


    Sjogren's syndrome dry eye (SSDE) mainly affects middle-aged women and can negatively affect women's psychological and social functioning. However, little is known about the correlation between vision-related quality of life (VR-QoL) and psychological status for women with SSDE. We therefore examined VR-QoL and psychological status in two groups of Chinese women: an SSDE group and a non-SSDE group. We also explored the associations between VR-QoL scores, sociodemographic measures, ophthalmologic parameters, and psychological status in women with SSDE. The case-control study recruited 30 female outpatients with SSDE and 30 without SSDE from the Eye and Ear, Nose, and Throat (ENT) Hospital of Fudan University. Demographic and ophthalmologic data were collected from all participants. Ophthalmologic examinations included best-corrected visual acuity (BCVA), corneal fluorescein staining (CFS), tear break-up time (TBUT) and Schirmer test. Data collected using the National Eye Institute's Visual Function Questionnaire (NEI-VFQ) and Ocular Surface Disease Index (OSDI) survey instruments were analyzed to identify potential differences in VR-QoL between the SSDE group and the non-SSDE group. We also used the Zung Self-Rating Anxiety and Self-Rating Depression Scales (SAS and SDS) to determine psychological status in both groups. The SSDE group scored significantly lower than the non-SSDE group on the NEI-VFQ subscales of general health, general vision, and long-distance vision activities (all p vision and peripheral vision. The composite OSDI score and its three subscale scores for the women in the SSDE group were all positively correlated with overall SAS/SDS scores (all p values were <0.05). Both VR-QoL and psychological status were significantly worse in SSDE group than in the non-SSDE group. The VR-QoL of women with SSDE had a negative correlation with their anxiety and depression levels.

    Phieffer, Laura; Hefner, Jennifer L; Rahmanian, Armin; Swartz, Jason; Ellison, Christopher E; Harter, Ronald; Lumbley, Joshua; Moffatt-Bruce, Susan D

    Operating rooms (ORs) are costly to run, and multiple factors influence efficiency. The first case on-time start (FCOS) of an OR is viewed as a harbinger of efficiency for the daily schedule. Across 26 ORs of a large, academic medical center, only 49% of cases started on time in October 2011. The Perioperative Services Department engaged an interdisciplinary Operating Room Committee to apply Six Sigma tools to this problem. The steps of this project included (1) problem mapping, (2) process improvements to preoperative readiness, (3) informatics support improvements, and (4) continuous measurement and feedback. By June 2013, there was a peak of 92% first case on-time starts across service lines, decreasing to 78% through 2014, still significantly above the preintervention level of 49% (p = .000). Delay minutes also significantly decreased through the study period (p = .000). Across 2013, the most common delay owners were the patient, the surgeon, the facility, and the anesthesia department. Continuous and sustained improvement of first case on-time starts is attributed to tracking the FCOS metric, establishing embedded process improvement resources and creating transparency of data. This article highlights success factors and barriers to program success and sustainability.

  1. Acute acalculous cholecystitis immediately after gastric operation: Case report and literatures review (United States)

    Liu, Feng-Lin; Li, He; Wang, Xue-Fei; Shen, Kun-Tang; Shen, Zhen-Bin; Sun, Yi-Hong; Qin, Xin-Yu


    Acute acalculous cholecystitis (AAC) is a rare complication of gastric surgery. The most commonly accepted concepts regarding its pathogenesis are bile stasis, sepsis and ischemia, but it has not been well described how to identify and manage this disease in the early stage. We report three cases of AAC in elderly patients immediately after gastric surgery, which were treated with three different strategies. One patient died 42 d after emergency cholecystectomy, and the other two finally recovered through timely cholecystostomy and percutaneous transhepatic gallbladder drainage, respectively. These cases informed us of the value of early diagnosis and proper treatment for perioperative AAC after gastric surgery. We further reviewed reported cases of AAC immediately after gastric operation, which may expand our knowledge of this disease. PMID:25132787

  2. Analysis of 1014 consecutive operative cases to determine the utility of intraoperative neurophysiological data (United States)

    Hussain, Namath Syed


    Introduction: Intraoperative neurophysiological monitoring (IOM) during neurosurgical procedures has become the standard of care at tertiary care medical centers. While prospective data regarding the clinical utility of IOM are conspicuously lacking, retrospective analyses continue to provide useful information regarding surgeon responses to reported waveform changes. Methods: Data regarding clinical presentation, operative course, IOM, and postoperative neurological examination were compiled from a database of 1014 cranial and spinal surgical cases at a tertiary care medical center from 2005 to 2011. IOM modalities utilized included somatosensory evoked potentials, transcranial motor evoked potentials, pedicle screw stimulation, and electromyography. Surgeon responses to changes in IOM waveforms were recorded. Results: Changes in IOM waveforms indicating potential injury were present in 87 of 1014 cases (8.6%). In 23 of the 87 cases (26.4%), the surgeon responded by repositioning the patient (n = 12), repositioning retractors (n = 1) or implanted instrumentation (n = 9), or by stopping surgery (n = 1). Loss of IOM waveforms predicted postoperative neurological deficit in 10 cases (11.5% of cases with IOM changes). Conclusions: In the largest IOM series to date, we report that the surgeon responded by appropriate interventions in over 25% of cases during which there were IOM indicators of potential harm to neural structures. Prospective studies remain to be undertaken to adequately evaluate the utility of IOM in changing surgeon behavior. Our data is in agreement with previous observations in indicating a trend that supports the continued use of IOM. PMID:26396602

  3. Piaget, Pedagogy, and Evolutionary Psychology

    Directory of Open Access Journals (Sweden)

    Jeremy E. C. Genovese


    Full Text Available Constructivist pedagogy draws on Piaget's developmental theory. Because Piaget depicted the emergence of formal reasoning skills in adolescence as part of the normal developmental pattern, many constructivists have assumed that intrinsic motivation is possible for all academic tasks. This paper argues that Piaget's concept of a formal operational stage has not been empirically verified and that the cognitive skills associated with that stage are in fact “biologically secondary abilities” (Geary and Bjorklund, 2000 culturally determined abilities that are difficult to acquire. Thus, it is unreasonable to expect that intrinsic motivation will suffice for most students for most higher level academic tasks. In addition, a case is made that educational psychology must incorporate the insights of evolutionary psychology.

  4. Acute psychological stress as a precipitant of acute coronary syndromes in patients with undiagnosed ischemic heart disease: a case report and literature review. (United States)

    Zupancic, Melanie L


    Acute psychological stress causes a number of physiologic responses that can trigger acute coronary syndromes in individuals with silent coronary artery disease. The mechanisms behind this phenomena have been the subject of much speculation. The following is a case report and brief review of the literature. A PubMed search was undertaken using the key words stress and myocardial infarction, stress and ischemia, mental stress and coronary artery disease, psychological stress and acute coronary syndrome, and mental stress and plaque destabilization. Articles were restricted to the English language and those dating through December 2007. Acute coronary syndrome is thought to be the end result of a complex mechanism involving platelet activation and endothelial dysfunction. Several studies have shown that acute mental stress leads to enhanced platelet activation and endothelial dysfunction. The mechanism behind this involves both the autonomic nervous system and the neuroendocrine response. Acute psychological stress may lead to acute coronary syndromes in patients with previously silent disease. Physicians should inquire about cardiac symptoms in patients with cardiac risk factors who are experiencing psychological distress. Further research will hopefully lead to an improved understanding of the mechanism behind this process to improve therapeutic interventions.

  6. Decrease in case duration required to complete an additional case during regularly scheduled hours in an operating room suite: a computer simulation study. (United States)

    Dexter, F; Macario, A


    We used Monte-Carlo computer simulation to determine whether surgical or anesthetic interventions to achieve small decreases in case duration may create enough new open operating room (OR) time to permit an additional case to be scheduled for completion in an OR suite during regular working hours. We used rules for scheduling of cases assuming that OR personnel are compensated so that the OR suite can profit financially from decreasing case duration to complete an additional case during regularly scheduled hours. The decreases in each case's duration required to create enough new open OR time to reliably (> or =95%) schedule another case were 30-39 min, 79-110 min, and 105-206 min for OR suites with 1-15 ORs and mean case durations of 1, 2, or 3 h, respectively. Computer simulation shows decreasing case duration is unlikely to create sufficient operating room time to reliably permit an additional case to be scheduled for completion during working hours. Additional cases may best be added to the operating room suite schedule by optimizing case scheduling, not by decreasing the duration of all cases in the suite.

    The importance of effective communication, a key component of teamwork, is well recognised in the healthcare setting. Establishing a culture that encourages and empowers team members to speak openly in the cardiothoracic (CT) operating room (OR) is necessary to improve patient safety in this high-risk environment. This study will take place at Barnes-Jewish Hospital, an academic hospital in affiliation with Washington University School of Medicine located in the USA. All team members participating in cardiac and thoracic OR cases during this 17-month study period will be identified by the primary surgical staff attending on the OR schedule.TeamSTEPPS (Team Strategies and Tools to Enhance Performance and Patient Safety) training course will be taught to all CT OR staff. Before TeamSTEPPS training, staff will respond to a 39-item questionnaire that includes constructs from the Agency for Healthcare Research and Quality Hospital Survey on Patient Safety Culture, Edmondson's 'Measure of psychological safety' questionnaire, and questionnaires on turnover intentions, job satisfaction and 'burnout'. The questionnaires will be readministered at 6 and 12 months.The primary outcomes to be assessed include the perceived psychological safety of CT OR team members, the overall effect of TeamSTEPPS on burnout and job satisfaction, and observed turnover rate among the OR nurses. As secondary outcomes, we will be assessing self-reported rates of medical error and near misses in the ORs with a questionnaire at the end of each case. Ethics approval is not indicated as this project does not meet the federal definitions of research requiring the oversight of the Institutional Review Board (IRB). Patient health information (PHI) will not be generated during the implementation of this project. Results of the trial will be made accessible to the public when published in a peer-reviewed journal following the completion of the study. © Article author(s) (or their employer(s) unless

    Kidd, Sean A


    The use of inadequate operational definitions of suicidal behavior is often a limitation of suicide research. In this article, the results of an exploratory qualitative study of street youth suicidality is contrasted with the existing literature to highlight the problems associated with defining suicidal behaviors. It is argued through the use of the case example of street youth that accurate and detailed assessment of suicidal history, context, and intent is necessary to avoid substantial threats to the validity and clinical use of research findings.

  11. [Experiences of breast reconstruction following mastectomy in cases of cancer and evaluation of psychological aspects of the patients]. (United States)

    Bando, M


    The breasts are one of the symbols of femininity. Even if it is for the treatment of cancer, the loss or deformity of the breast brings a considerable psychological burden in addition to the physical pain. Authors have performed breast reconstruction on 150 cases during the past fifteen years and have obtained largely favorable results, which were already reported in several papers. Authors administered questionnaires to these patients in order to ascertain their candid opinions which are often not expressed in a hospital. The results of the survey are presented in this report. The survey was conducted anonymously and the questions were all multiple-choices. Approximately 82% of the patient responded. About the pain, inconvenience and motives for undergoing reconstruction, there was a wide variety of answers and many of those surprised authors. For instance; hesitant to go to a hot spring, or on a trip with friends (76%), hesitant to go to a clinic or a hospital for physical check-ups and common illness (74%), troublesome to wear special underwear (69%), inconvenient because ordinary clothes cannot be worn (56%), distressed when viewing own body (52%), unable to dress in thin clothes in hot summer season (50%), imbalance of the breasts (49%), inconvenient to participate in sports (47%). The most patients experienced inconveniences in daily life and had mental and emotional problems. Overall, an impression of the results of breast reconstruction was 83% satisfactory or near satisfaction. About the condition after reconstruction: Patients also expressed a wide variety of opinions about the improvements. For instance, they are relieved from the troubles of wearing special clothing and enjoy selecting and shopping for clothes. They are able to walk on the street with dignity. They enjoy hot spring baths, sports, and leisure activities. They can go for physical check-ups without hesitation. They have a sense of liberation, and become free from constant anxiety. They

  12. Psoriasis: 'the badge of shame'. A case report of a psychological intervention to reduce and potentially clear chronic skin disease. (United States)

    Shah, R; Bewley, A


    The psychological effects of skin disorders have long been established. Most research on psychological interventions for people with skin disorders has focused predominantly on cognitive behavioural therapy (CBT); however, CBT is not appropriate for everyone. We assessed the benefits of a psychological intervention, using the principles of systemic family therapy (SFT). The key to SFT is the understanding of problems in the context of family and social relationships, and how reciprocal dynamics influence problems. Problems thus have a dual construction; they do not exist only within individuals but rather are a product of the interactions between people and wider systems, such as communities and cultures. This report focuses on the importance of practice-based evidence and the need for more research. A 46-year-old female with a 40-year history of psoriasis was referred for psychological therapy for feelings of shame and low self-esteem. Many medications, including biologics, had been tried previously with no success. Initially, the patient attended therapy alone; later, her husband and other family members joined her. Issues around her past, relationships, and personal beliefs/assumptions were explored. Over ten 50-min sessions, she was able to view her dynamics and relationships in a more helpful way. Her psoriasis cleared, reinforcing that it may have been caused by underlying psychological difficulties. Dermatologists need to work in a more holistic way to provide quality care to patients, meeting their psychological and dermatological needs. There is also a need to develop a broader evidence base and interventions for people with skin disorders. © 2014 British Association of Dermatologists.

    Hae Ryong Song


    Full Text Available Metatropic dysplasia is a rare but severe spondyloepimetaphyseal dysplasia characterized by long trunk and short extremities. The exact incidence is not known; however, 81 cases have been reported in the literature till now. Due to progressive kyphoscoliosis, there is a reversal of proportions in childhood (shortening of trunk with relative long extremities. The diagnostic radiographic findings include marked platyspondyly (wafer-thin vertebral bodies, widened metaphyses (dumbbell-shaped tubular bones and small epiphysis and a specific pelvic shape. The severe kyphoscoliosis is relentless and resistant to conservative treatment with bracing. Operative treatment is controversial due to the recurrence of deformity despite aggressive correction. We, herein report a case of this rare dysplasia and its follow-up after corrective surgery for spine and limb deformity. The excellent correction and good functional pulmonary status at 6-year follow-up has never been previously reported.

    Full Text Available This article aims at presenting a multiple case study in which we measured the prioritization given to competitive factors by six companies that buy rice products for retailing. The multiple case study took place in six large self-service food agents that operate in Santa Catarina and Rio Grande do Sul. The competition in the industry was described by a tree-like structure, which first layer includes: price, quality, variety, image, deliver and services as competitive factors. For prioritizing, we distributed relative importance between factors, with the aid of the AHP method of multicriteria decision support. Quality was prioritized in five companies. The other one prioritized variety. Internal comparisons were made with the results from second layer of the structure.

  15. Open-Source as a strategy for operational software - the case of Enki (United States)

    Kolberg, Sjur; Bruland, Oddbjørn


    Since 2002, SINTEF Energy has been developing what is now known as the Enki modelling system. This development has been financed by Norway's largest hydropower producer Statkraft, motivated by a desire for distributed hydrological models in operational use. As the owner of the source code, Statkraft has recently decided on Open Source as a strategy for further development, and for migration from an R&D context to operational use. A current cooperation project is currently carried out between SINTEF Energy, 7 large Norwegian hydropower producers including Statkraft, three universities and one software company. Of course, the most immediate task is that of software maturing. A more important challenge, however, is one of gaining experience within the operational hydropower industry. A transition from lumped to distributed models is likely to also require revision of measurement program, calibration strategy, use of GIS and modern data sources like weather radar and satellite imagery. On the other hand, map based visualisations enable a richer information exchange between hydrologic forecasters and power market traders. The operating context of a distributed hydrology model within hydropower planning is far from settled. Being both a modelling framework and a library of plugin-routines to build models from, Enki supports the flexibility needed in this situation. Recent development has separated the core from the user interface, paving the way for a scripting API, cross-platform compilation, and front-end programs serving different degrees of flexibility, robustness and security. The open source strategy invites anyone to use Enki and to develop and contribute new modules. Once tested, the same modules are available for the operational versions of the program. A core challenge is to offer rigid testing procedures and mechanisms to reject routines in an operational setting, without limiting the experimentation with new modules. The Open Source strategy also has

    Directory of Open Access Journals (Sweden)

    Luiz Felipe Scavarda

    Full Text Available Abstract Adequate preparation, learning, and training is required for Sales and Operations Planning (S&OP to aid organizations in achieving the full expected benefits from its implementation. This paper presents a case method for S&OP and the learning experience of its application at the University of Münster (Germany. The “constructive alignment principle” was applied with a “team teaching” approach, involving an executive from the case company. Students improved their knowledge on S&OP and their analytical skills by understanding the conceptual S&OP building blocks and by learning how to deal with them to provide a solution for a case based on a real-life situation. The learning results were evaluated positively during the discipline’s student evaluation of teaching (SET. The applied case method enhanced the student’s motivation and engagement (e.g., higher preparation effort and class attendance, which were considered higher than in other disciplines with the traditional lecture-based education.

However, they are not specified for this application and their sizes do not enable their use in the operative room to control the excision of the all SLN. We present the results obtained with a prototype of a new mini gamma camera developed especially for the operative lymphoscintigraphy of the axillary area in case of breast cancer. This prototype is composed of 10 mm thick parallel lead collimator, a 2 mm thick GSO:Ce inorganic scintillating crystal from Hitachi and a Hamamatsu H8500 flat panel multianode (64 channels) photomultiplier tube (MAPMT) equipped with a dedicated electronics. Its actual field of view is 50 × 50mm2. The gamma interaction position in the GSO scintillating plate is obtained by calculating the center of gravity of the fired MAPMT channels. The measurements performed with this prototype demonstrate the usefulness of this mini gamma camer...

  3. [Unexpected atrial fibrillation when monitoring in operating room. Case of the trimester]. (United States)


    A real case reported to the SENSAR database of incidents is presented. In a patient scheduled for nose fracture repair surgery an unexpected atrial fibrillation was found when monitored in the operating room. The operation was not delayed. After induction of general anaesthesia heart rate suddenly increased and hemodinamic situation was impaired. Cardioversion was required. Two electric countershocks were given but sinus rhythm was not restored. Heart rate was controlled with amiodarone infusion. Optimal defibrillation characteristics are described in these cases. Increased risk of thromboembolism (1-2%) following cardioversion is present even if atrial thrombi are ruled out. The mainstay therapies of are rhythm and rate control and prevention of thromboembolic complications. We describe recommendations on the management of these critical situations with emphasis in learning through the creation of protocols and training practice in simulation.

  5. Investigative psychology


    Canter, David V.


    The domain of Investigative Psychology covers all aspects of psychology that are relevant to the conduct of criminal or civil investigations. Its focus is on the ways in which criminal activities may be examined and understood in order for the detection of crime to be effective and legal proceedings to be appropriate. As such Investigative Psychology is concerned with psychological input to the full range of issues that relate to the management, investigation and prosecution of crime

  6. A case study of school support and the psychological, emotional and behavioural consequences of HIV and AIDS on adolescents. (United States)

    Asikhia, Olubusayo Aduke; Mohangi, Kesh


    Various studies have reported a huge increase in the numbers of orphaned adolescents in Sub-Saharan Africa and its effects on their psychological, emotional and behavioural development. Yet, their needs are seldom recognised or adequately addressed in policy and programmes.This article uses a qualitative study to report the experiences of 11 orphaned adolescents (5 boys and 6 girls aged between 15 and 18 years) affected by HIV and AIDS in a secondary school (in Atteridgeville, Pretoria, South Africa) and the school support provided by them. The primary data-generation strategies were informal interviews and the Beck Youth Inventories-II (BYI-II) (adopted to measure the participants' level of emotional, behavioural and psychological problems). All interview transcriptions with the participants were thematically analysed. BYI-II data were subjected to T scores (in percentages) to know the participant's psychological, behavioural and emotional problems in order to compare it with their perceptions on the degree of support provided by the school. Result shows that participants have a high prevalence of psychological, behavioural and emotional problems and that the school support provided to them (teachers' support, the general school environment and the degree of discrimination, labelling and bullying that exists in the school) was not sufficient. The participants, however, reported a high level of support from the principal. In conclusion, we have suggested the urgent need for teachers to acquire and possess basic knowledge and skills in caring and paying attention to learners affected by HIV and AIDS and for government agencies and NGOs working with HIV-and AIDS-affected children, to focus on proposals that address the psychological, behavioural and emotional problems in such affected adolescents.

  7. Impact of Water Availability on Regional Power System Operations - A Case Study of ERCOT (United States)

    Levin, T.; Zhou, Z.


    Impact of water availability on regional power system operations - A case study of ERCOT Thermal power plants are the largest single source of water withdrawals in the United States, mainly for cooling purposes. The amount of water that is required for cooling is highly dependent on a number of factors including the generation technologies being used, the temperature of the input water, and the total electricity load in the system. During summer months, many of these factors coincide to greatly increase the demand for water in a power system. Electricity demand typically reaches its annual peak when temperatures are high due to increased air conditioning loads. Ambient water temperatures also increase, meaning that greater quantities of water are required to provide the same amount of cooling at thermal generation plants. Finally, water availability is generally constrained due to seasonal effects and potential droughts. This raises concerns that water scarcity may lead to forced de-rating at some power plants during periods of peak demand, resulting in a more vulnerable and less reliable energy system. While increasing attention has recently been given to the inexorable link between water and energy, most commercial power models do not explicitly account for water use when optimizing system operation. We apply the AURORAxmp power modeling software to a case study analysis of the ERCOT power system to determine the water requirements of the system during periods of peak power demand. We then analyze water availability by location and time to identify potential supply shortages, which may reduce actual power generation availability. These data are fed back into the power systems model and specific generation units are de-rated as necessitated by water constraints. We then analyze these results to determine how the optimal generation mix, system reliability, and wholesale electricity prices may be affected by when the ERCOT power system is operated under water

  8. Estimating the receiver operating characteristic curve in studies that match controls to cases on covariates. (United States)

    Pepe, Margaret Sullivan; Fan, Jing; Seymour, Christopher W


    Studies evaluating a new diagnostic imaging test may select control subjects without disease who are similar to case subjects with disease in regard to factors potentially related to the imaging result. Selecting one or more controls that are matched to each case on factors such as age, comorbidities, or study site improves study validity by eliminating potential biases due to differential characteristics of readings for cases versus controls. However, it is not widely appreciated that valid analysis requires that the receiver operating characteristic (ROC) curve be adjusted for covariates. We propose a new computationally simple method for estimating the covariate-adjusted ROC curve that is appropriate in matched case-control studies. We provide theoretical arguments for the validity of the estimator and demonstrate its application to data. We compare the statistical properties of the estimator with those of a previously proposed estimator of the covariate-adjusted ROC curve. We demonstrate an application of the estimator to data derived from a study of emergency medical services encounters where the goal is to diagnose critical illness in nontrauma, non-cardiac arrest patients. A novel bootstrap method is proposed for calculating confidence intervals. The new estimator is computationally very simple, yet we show it yields values that approximate the existing, more complicated estimator in simulated data sets. We found that the new estimator has excellent statistical properties, with bias and efficiency comparable with the existing method. In matched case-control studies, the ROC curve should be adjusted for matching covariates and can be estimated with the new computationally simple approach. Copyright © 2013 AUR.

  11. Theorising context in psychology

    DEFF Research Database (Denmark)

    Glaveanu, Vlad Petre


    This article aims to address the issue of what context is and how it can be incorporated in psychological theory by using the case study of creativity research. It starts from a basic definition of context as the spatiotemporal continuum that, together with psychological phenomena, constitutes...... a totality and should be considered a single, integrated whole. As such, contexts are neither subjective, existing only in perception, nor are they a set of variables external to the person, but participate directly in the processes under study in psychology. We can therefore distinguish between “flat......” theorising, one-dimensional and overconcerned with intra-psychological factors, and “3-D” models trying to articulate the psychological, the spatial (sociomaterial), and the temporal. These categories are illustrated by different theoretical approaches to creativity. It is argued here that a cultural...

  12. Evaluation of the treatment of autopsied cases of carcinoma of the cervix with reference to surgical operation and radiotherapy

    Ogawa, Masatoshi; Suzuki, Mitsuaki; Takeda, Hideo; Jobo, Toshiko; Arai, Masao (Kitasato Univ., Sagamihara, Kanagawa (Japan). School of Medicine)


    Results of thirty two autopsies in the cases of carcinoma of the cervix experienced in ten years were analyzed. Fourteen cases received surgery and postoperative irradiation. Fourteen cases had external irradiation combined with intracavitary irradiation. Cancer was the cause of death in 81.3% of the whole cases, and it caused cachexia in many cases of the two groups. Uremia and uremic complication were found in 8 cases of the operative group, and in 2 of the radiotherapy group. High incidences of intrapelvic local recurrence and metastasis to other organs were found in the operative group. Cancerous infiltrative involvement of the bladder was often observed, such as in 11 cases of the operated group and in 9 cases of the irradiation group. Cancerous hydronephrosis was found in 10 and 5 cases of the operation and irradiation group, respectively; non-cancerous hydronephrosis was found in 2 of the former and in 4 of the latter. The radiotherapy group had a longer survival period than the other, without severe side effects in the urinary system. This suggested that radiotherapy is of value in treatment of cervical cancer.

  14. Effects of animal-assisted therapy on behavioral and/or psychological symptoms in dementia: a case report. (United States)

    Nordgren, Lena; Engström, Gabriella


    Recently, interest in nonpharmaceutical interventions in dementia care has increased. Animal-assisted therapy has been shown to be one promising intervention but more knowledge is needed. The present article reports on a pilot study involving an 84-year-old woman with vascular dementia who was systematically trained with a therapy dog team for 8 weeks. A quasi-experimental longitudinal interventional design with pre-post measures was used. Data were collected on 3 occasions. Descriptive statistics were used for data analysis. Some effects on the woman's ability to walk and move were identified. In addition, some effects in the woman's cognitive state were observed. Physical, psychological, and/or social training with certified therapy dog teams can have effects on behavioral and psychological symptoms in people living with dementia. Further research is needed.

  15. The history of psychological categories. (United States)

    Smith, Roger


    Psychological terms, such as 'mind', 'memory', 'emotion' and indeed 'psychology' itself, have a history. This history, I argue, supports the view that basic psychological categories refer to historical and social entities, and not to 'natural kinds'. The case is argued through a wide ranging review of the historiography of western psychology, first, in connection with the field's extreme modern diversity; second, in relation to the possible antecedents of the field in the early modern period; and lastly, through a brief introduction to usage of the words 'soul', 'mind', 'memory' and 'emotion'. The discussion situates the history of psychology within a large historical context, questions assumptions about the continuity of meaning, and draws out implications for the philosophical and social constitution of 'psychology' and 'the psychological' from the existing literature. The historical evidence, this paper concludes, does not support the conventional presumption that modern psychological terms describe 'natural kinds'.

  17. A strategy to decide whether to move the last case of the day in an operating room to another empty operating room to decrease overtime labor costs. (United States)

    Dexter, F


    We examined how to program an operating room (OR) information system to assist the OR manager in deciding whether to move the last case of the day in one OR to another OR that is empty to decrease overtime labor costs. We first developed a statistical strategy to predict whether moving the case would decrease overtime labor costs for first shift nurses and anesthesia providers. The strategy was based on using historical case duration data stored in a surgical services information system. Second, we estimated the incremental overtime labor costs achieved if our strategy was used for moving cases versus movement of cases by an OR manager who knew in advance exactly how long each case would last. We found that if our strategy was used to decide whether to move cases, then depending on parameter values, only 2.0 to 4.3 more min of overtime would be required per case than if the OR manager had perfect retrospective knowledge of case durations. The use of other information technologies to assist in the decision of whether to move a case, such as real-time patient tracking information systems, closed-circuit cameras, or graphical airport-style displays can, on average, reduce overtime by no more than only 2 to 4 min per case that can be moved. The use of other information technologies to assist in the decision of whether to move a case, such as real-time patient tracking information systems, closed-circuit cameras, or graphical airport-style displays, can, on average, reduce overtime by no more than only 2 to 4 min per case that can be moved.

  18. . Psychological Pricing in Modern Retailing: The Case of Wine Sector in Hard-Discounter Chains of Russia

    Directory of Open Access Journals (Sweden)

    Nikola Perovic


    Full Text Available The main goal of this paper is to show if is possible to find a modern retail chain in one of the world largest economies that uses exclusively psychological pricing, as a dominant competitive advantage, in order to predominantly direct consumer behavior. Pricing, as a source of competitive advantage is the least explained in marketing literature, therefore it is important to contribute and show how psychological pricing is a source of competitive advantage. It could be an evidence to support the firm belief which exists among many retailers that greater than expected demand occurs at psychological price points. We shall analyze different retail chains belonging to so call hard-discounters in Russian Federation using method of observation and choose one sector in order to check the hypothesis. Hard-discounters are chosen since they use pricing strategies as the most important element of marketing program, much more important than products, promotion or sales channels, while Russia has been chosen as the largest growing wine market in the world.

  19. Scheduling non-operating room anesthesia cases in endoscopy: Using the sandbox analogy. (United States)

    Tsai, Mitchell H; Cipri, Leah A; O'Donnell, Stephen E; Matthew Fisher, J; Andritsos, Dimitrios A


    For many hospitals, the non-operating room anesthesia (NORA) workload continues to expand. We developed a new NORA scheduling process with shared block time - a sandbox - amongst all of the gastroenterology groups and measured the efficacy of the intervention using basic operating room management metrics. Prospective analysis, statistical process control. Academic, rural hospital; endoscopy suite; postoperative recovery area. Adults and pediatric patients undergoing elective and/or urgent endoscopic procedures. In 2014, we divided the NORA block allocations on Thursdays into one afternoon block for pediatric GI, and 1.5 blocks to be shared between the two adult GI groups. We made a provision for an additional afternoon block available if necessary. No changes were made in the release policy. For scheduling, shared block time was released between the three endoscopy groups at 7days and then opened to the general pool at 48h. Case volumes, under-utilized time (opportunity-unused), elective time-in-block, over-utilized time. With the addition of a pediatric gastroenterologist, the number of cases per month increased after the change in scheduling procedure from a mean of 107 cases per month to 131, an increase of 23% (p=Chart 1). Elective time-in-block increased after the intervention by 13% (p=0.09), while under-utilized time (opportunity-unused time) decreased in a reciprocal fashion (15%, p=0.03). Pre-intervention mean over-utilized time was 101min/month, while post-intervention over-utilized time decreased by 84.5% (99% CI ±3.29) to a mean of 16min/month. By using a multi-disciplinary, team-based approach, we were able to increase throughput without increasing under-utilized or over-utilized time, thereby increasing efficiency. Despite the additional cases brought in by the pediatric gastroenterologist, opportunity-unused time decreased only moderately-lending support to our prediction that opening an additional NORA block was not only unnecessary to accommodate

    A system that applies a method of knowledge-intensive case-based reasoning, for repair and prevention of unwanted events in the domain of offshore oil well drilling, has been developed in cooperation with an oil company. From several reoccurring problems during oil well drilling the problem of 'lost circulation', i.e. loss of circulating drilling fluid into the geological formation, was picked out as a pilot problem. An extensive general knowledge model was developed for the domain of oil well drilling. Different cases were created on the basis of information from one Mexican Gulf operator. When the completed CBR-system was tested against a new case, cases with descending similarity were selected by the tool. In an informal evaluation, the two best fitting cases proved to give the operator valuable advise on how to go about solving the new case (author)

  1. An examination of the psychological aspects of bite marks. (United States)

    Walter, R A


    The intent of this paper is to present some psychological threads which appear to be operative for the perpetrator of bite marks. In the catalogue of multiple motivations, there appears to be a current theme of power, control, potency, and the attempt to have a psychological symbolization of the perpetrator's omniscient capacity for absorbing life essences. In an examination of these highly complex needs, the modern perpetrator appears to act out consistently with cultural biases coupled with immediate psychological needs which have pressed for expression. Due to a pattern of psychologically expressed ritualism, the perpetrator will often inadvertently leave important psychological clues at the crime scene. The attack style, mode of death, characteristics of the victim, etc.--these components reveal the information on the type of psychological needs that the perpetrator is trying to satisfy. In the cases of bite marks associated with violent crime, it becomes crucial to an "investigator" what type of personality characteristics are welded together to form this kind of need complex. After reviewing cases reported in the literature and after conducting psychological interviews with perpetrators, three major groups of perpetrators seem to be apparent. The first group is motivated out of an anger track, the second group is motivated out of sadistic biting, and the third is out of the more traditional "cannibal complex" motif.

  2. Management of intra-operative acute pulmonary embolism during general anesthesia: a case report. (United States)

    Mao, Yuanyuan; Wen, Shuai; Chen, Gezi; Zhang, Wei; Ai, Yanqiu; Yuan, Jingjing


    Acute pulmonary embolism (APE) can be life-threatening. Early detection is even more difficult for patients under general anesthesia as common symptoms are not available and the pathophysiological course of intra-operative APE is influenced by procedures of surgery and anesthesia, which makes patients under general anesthesia a distinctive group. We report a case of APE during orthopedic surgery under general anesthesia. A 64-year-old female with atrial fibrillation and surgical history of varicosity underwent total right hip replacement surgery under general anesthesia. No arterial or deep vein thrombosis (DVT) was found prior to the surgery, but APE still occurred intraoperatively. The sudden decrease in PETCO2 and increase in PaCO2 combined other clues raised the suspect of APE, which is further evidenced by transesophageal echocardiogram (TEE). Multidisciplinary consultation was started immediately. After discussion with the consultation team and communication with patient's family members, anticoagulation therapy was started and IVC filter was placed to prevent PE recurrence. The patient went through the operation and discharged uneventfully 30 days later. Pulmonary embolism is a rare and potentially high-risk perioperative situation, with a difficult diagnosis when occurs under anesthesia. The separation phenomenon of decrease in PETCO2 and increase in PaCO2 might be a useful and suggestive sign, enabling prompt management and therefore improving the prognosis.

  3. A test case of computer aided motion planning for nuclear maintenance operation

    Needs for improved tools for nuclear power plant maintenance preparation are expressed by EDF engineering. These are an easier and better management of logistics constraints such as free spaces for motions or handling tasks. The lack of generic or well suited tools and the specificity of nuclear maintenance operation have led EDF R and D to develop its own motion planning tools in collaboration with LAAS-CNRS, Utrecht University and the software publisher CADCENTRE within the framework of the three years Esprit LTR project MOLOG. EDF users needs will be summed up in the first part of the paper under the title ''Motion feasibility studies for maintenance operation'' and then compared to the current industrial offer in the ''Software's background'''s part. The definition and objectives ''Towards motion planning tools'' follows. It explains why maintenance preparation pertains to automatic motion planning and how it makes studies much simpler. The ''MOLOG's Benchmark and first result'''s part describes the test-case used to evaluate the MOLOG project and gives an outlook at the results obtained so far. (author)

    Fujiwara, Satoru; Yoshimura, Hajime; Nishiya, Kenta; Oshima, Keiichi; Kawamoto, Michi; Kohara, Nobuo


    A 67-year-old man presented with hoarseness, dysarthria and deviation of the tongue to the left side the day after the open-heart operation under general anesthesia. Brain MRI demonstrated no causal lesion, and laryngoscope showed left vocal cord abductor palsy, so we diagnosed him with Tapia's syndrome (i.e., concomitant paralysis of the left recurrent and hypoglossal nerve). His neurological symptoms recovered gradually and improved completely four months after the onset. Tapia's syndrome is a rare condition caused by the extra cranial lesion of the recurrent laryngeal branch of the vagus nerve and the hypoglossal nerve, and mostly described as a complication of tracheal intubation. In this case, transesophageal echo probe has been held in the left side of the pharynx, so compression to the posterior wall of pharynx by the probe resulted in this condition, and to the best of our knowledge, this is the first report of Tapia's syndrome due to transesophageal echocardiography during an open-heart operation. This rare syndrome should be considered as a differential diagnosis of dysarthria and tongue deviation after a procedure associated with compression to the pharynx.

  5. Exploring the Politics of Water Grabbing: The Case of Large Mining Operations in the Peruvian Andes

    Directory of Open Access Journals (Sweden)

    Milagros Sosa


    Full Text Available The operations of the large mining company Yanacocha in Cajamarca (Peru provoke and require a fundamental reshuffling of how rights to water are allocated, resulting in changes in the distribution of the benefits and burdens of accessing water. We use this paper to argue that these changes in water use and tenure can be understood as a form of water grabbing, since they result in a transfer of water control from farmers’ collectives and government agencies to the mining company, with the company also assuming de facto responsibility over executing water allocation and safeguarding certain water-quality levels. We illustrate – by using two cases: La Ramada canal and the San José reservoir – the company’s overt and covert strategies to achieve control over water, showing how these are often backed up by neo-liberal government policies and by permissive local water authorities. Next to active attempts to obtain water rights, these strategies also include skilfully bending and breaking the resistance of (some farmers through negotiation and offering compensation. The de facto handing over of water governance powers to a multinational mining company raises troubling questions about longer-term water management, such as who controls the mining company, to whom are they accountable, and what will happen after mining operations stop.

    Baker, Janice L; Havas, Karyn A; Miller, Laura A; Lacy, Ward A; Schlanser, Justin


    To describe the patient population, injuries, and treatment received on the battlefield, and ultimate outcome of U.S. military working dogs that incurred gunshot wound (GSW) injury in Operation Enduring Freedom (Afghanistan) or Operation Iraqi Freedom (Iraq). Retrospective study between January 2003 and December 2009. Twenty-nine military working dogs from the U.S. military with confirmed GSW injuries incurred in combat in Operation Enduring Freedom or Operation Iraqi Freedom. None. Clinical data from battlefield treatment, which includes care from the point of injury through arrival to, but not including, a designated veterinary treatment facility. Twenty-nine dogs were injured between 2003 and 2009. All but one of the injuries were from high caliber, high velocity weapons. Of the 29 injured dogs, 11 survived the injuries and 18 died (38% survival rate). Of the dogs that died, all but 1 died from catastrophic nonsurvivable injuries before treatment or evacuation could be instituted. The thorax was the most common site of injury (50%) followed by extremity wounds (46%). The leading cause of death from GSWs was from thoracic wounds, followed by head wounds. Dogs with extremity wounds as their only injury were most likely to survive, and dogs with multiple injuries were least likely to survive. All surviving dogs received treatment at the point of injury by military medics and dog handlers consistent with Tactical Combat Casualty Care guidelines for combat injuries in human service members. Of the 11 that survived, all dogs returned to full duty with subsequent deployment to combat zones. Location of wounds and injury severity at the time of presentation to veterinary care was not correlated with length of time until return to duty. © Veterinary Emergency and Critical Care Society 2012.

  7. How much and what type: analysis of the first year of the acute care surgery operative case log. (United States)

    Dente, Christopher J; Duane, Therese M; Jurkovich, Gregory J; Britt, L D; Meredith, J Wayne; Fildes, John J


    A case log was created by the American Association for the Surgery of Trauma Acute Care Surgery (ACS) committee to track trainee operative experiences, allowing them to enter their cases in the form of Current Procedural Terminology (CPT) codes. We hypothesized that the number of cases an ACS trainee performed would be similar to the expectations of a fifth-year general surgery resident and that the current list of essential and desired cases (E/D list) would accurately reflect cases done by ACS trainees. The database was queried from July 1, 2011, to June 30, 2012. Trainees were classified as those in American Association for the Surgery of Trauma-accredited fellowships (ACC) and those in ACS fellowships not accredited (non-ACC). CPT codes were mapped to the E/D list. Cases entered manually were individually reviewed and assigned a CPT code if possible or listed as "noncodable." To compensate for nonoperative rotations and noncompliance, case numbers were analyzed both annually and monthly to estimate average case numbers for all trainees. In addition, case logs of trainees were compared with the E/D list to assess how well it reflected actual trainee experience. Eighteen ACC ACS and 11 non-ACC ACS trainees performed 16.4 (12.6) cases per month compared with 15.7 (14.2) cases for non-ACC ACS fellows (p = 0.71). When annualized, trainees performed, on average, 195 cases per year. Annual analysis led to similar results. The E/D list captured only approximately 50% of the trainees' operative experience. Only 77 cases were categorized as pediatric. ACS trainees have substantial operative experience averaging nearly 200 major cases during their ACS year. However, high variability exists in the number of essential or desirable cases being performed with approximately 50% of the fellows' operative experience falling outside the E/D list of cases. Modification of the fellows' operative experience and/or the rotation requirements seems to be needed to provide experience in

Erectile dysfunction (ED is a possible invalidating symptom of PD. The aim of this study was to evaluate the prevalence, psychological impact, and risk factors of ED in patients with PD. The study was conducted by carrying out a retrospective analysis of the clinical records of 309 patients with PD who visited our andrology clinic. All patients underwent the following tests: body mass index, common blood tests and hormone assays, questionnaire for erectile function assessment, dynamic penile color Doppler ultrasonography, imaging of the penis at maximum erection with photographic poses according to Kelâmi, psychosexual impact evaluation with PD Questionnaire (symptom bother score, evaluation of depression symptoms with the Patient Health Questionnaire-9, and evaluation of the intensity of penile pain with the pain intensity numeric rating scale. ED was observed in 37.5% of the cases. We divided the cases into two groups: group A (PD + ED, 116 cases, and group B (PD without ED, 193 cases. After multivariate analysis, we concluded that the following comorbidities are independent risk factors for ED: dyslipidemia, obesity, chronic prostatitis, benign prostatic hyperplasia, and autoimmune diseases. A depressive disorder was observed in 62.4%, and it was more frequent in patients with PD + ED (91.37% versus 45.07% group B. Sexual bother was greater in group A compared with group B (9.7 versus 7.6. Intensities of depressive symptoms and

  10. The Political Psychology in the Transatlantic Perspective – A Strategy Framework for Eastern Europe: the Case of Ukraine

    Directory of Open Access Journals (Sweden)

    Katerina Veljanovska Blazhevska


    Full Text Available Each nation tends to rationalize the situation, the past – the present and the future – in order to ensure normal living conditions and possible welfare. However, some internally and externally created policies aim to focus or defocus the public’s attention in order to distort the real picture. In political psychology, lies and intrigues are often associated with political effects. All these additional attributes guide the policy into the desired direction. The situation in Ukraine is a real example of a kind of "psychological warfare" of citizens caused as a result of claims made by the neighbouring Russian Federation, political steps and tactics of the European Union and the NATO Alliance. In order to prevent future negative development in this field, there is a need to create a common security strategy for Eastern Europe, as a result of the creation of successful Trans-Atlantic relations and good-neighbourly relations with the Russian Federation. The purpose of this paper is to describe the need for encouraging the creation of a rational attitude of the nations in order to strive for the improvement of the region in which they are located. The theory of public choice is applied as a basis of encouraging a better future in public policies and strategies in a country/region. Political psychology is the main thread utilised to disclose the real picture of relations in Ukraine, and the final results need to be used in the area of ​​creating a new security strategy for Eastern Europe. This work includes empirical research conducted within the Republic of Macedonia. The same applies to the theoretical frame of the paper.

  11. Psychological distress: concept analysis. (United States)

    Ridner, Sheila H


    The term 'distress' is frequently used in nursing literature to describe patient discomfort related to signs and symptoms of acute or chronic illness, pre- or post-treatment anxiety or compromised status of fetuses or the respiratory system. 'Psychological distress' may more accurately describe the patient condition to which nurses respond than does the term 'distress'. Psychological distress is seldom defined as a distinct concept and is often embedded in the context of strain, stress and distress. This creates confusion for nurses attempting to manage the care of people experiencing psychological distress. This paper is a concept analysis of psychological distress based on Walker and Avant's (1995) criteria that identifies the attributes, antecedents, and consequences of psychological distress based upon the findings of the literature review. In addition, empirical references are identified and constructed cases presented. A literature search was conducted using MEDLINE, CINAHL, Ovid, PsychINFO, and Cancer Lit databases over the last 50 years. The purposes of this concept analysis were: (1) to establish the concept of psychological distress as a clear and distinct concept, separate from strain, stress and distress, and (2) to provide nurses with a base of knowledge from which to plan effective clinical interventions. Content analysis of the literature revealed that, although used frequently in health care literature, the origin of the concept of psychological distress has not been clearly articulated and is ill-defined. Psychological distress is a serious problem faced by many of the people whom nurses encounter on a daily basis. An understanding of the concept of psychological distress will help nurses ameliorate this problem in patients. Nursing research related to the exploration of psychological distress is also needed.

    This paper discusses a theme touched upon in Robert Innis’s article on cultural psych- ology and philosophy, namely how we, within cultural psychology, seem to be undecided about how best to provide value on a societal level. It is discussed how psychology has provided us with several valuable...... tools for examining and understanding our own exist- ence, despite the fact that it is also a field that has seemed to be in one crisis after another since its inception. It is argued that cultural psychology is an intellectual tech- nology that allows us to peek under the hood of society, which...... is of utmost importance in today’s society, where democratic ideals are under severe pressure. Corporations, industries, and privileged individuals exercise increased control over political processes, having created obscure systems by which they operate. It is concluded that cultural psychology needs to find...

    Resch, Mária; Bella, Tamás


    In Hungary one can mostly find references to the psychological processes of politics in the writings of publicists, public opinion pollsters, philosophers, social psychologists, and political analysts. It would be still important if not only legal scientists focusing on political institutions or sociologist-politologists concentrating on social structures could analyse the psychological aspects of political processes; but one could also do so through the application of the methods of political psychology. The authors review the history of political psychology, its position vis-à-vis other fields of science and the essential interfaces through which this field of science, which is still to be discovered in Hungary, connects to other social sciences. As far as its methodology comprising psycho-biographical analyses, questionnaire-based queries, cognitive mapping of interviews and statements are concerned, it is identical with the psychiatric tools of medical sciences. In the next part of this paper, the focus is shifted to the essence and contents of political psychology. Group dynamics properties, voters' attitudes, leaders' personalities and the behavioural patterns demonstrated by them in different political situations, authoritativeness, games, and charisma are all essential components of political psychology, which mostly analyses psychological-psychiatric processes and also involves medical sciences by relying on cognitive and behavioural sciences. This paper describes political psychology, which is basically part of social sciences, still, being an interdisciplinary science, has several ties to medical sciences through psychological and psychiatric aspects.

    Full Text Available Psychological research in culturally plural societies has traditionally been divided into two domains: acculturation and ethnic relations. Berry’s model of acculturation and psychological well-being is highly regarded and widely recognized as in the field. His two-dimensional model of acculturation is based upon the multicultural ideology where individuals and groups are given the opportunity to choose among various elements of ethnic and host cultures to form their own unique blends of identity and culture. The findings support the Berry’s proposal that acculturation is two-dimensional (ethnic/cultural and host society identification for acculturating immigrants. But the process of acculturation is different depending on the life domains being considered. Youngsters do not endorse both cultures to the same degree in all domains, which means acculturation preferences for Turkish youngsters between the ages of 12-15 are domain dependent. In terms of average point acculturation preferences, Turkish youth endorsed integration more than any other acculturation strategies. Significant correlation was found among self-esteem and separation acculturation attitude for reading books domain. Second significant correlation was found among self-esteem and margina¬lization acculturation attitude for work domain.

  15. Psychology's Renaissance. (United States)

    Nelson, Leif D; Simmons, Joseph; Simonsohn, Uri


    In 2010-2012, a few largely coincidental events led experimental psychologists to realize that their approach to collecting, analyzing, and reporting data made it too easy to publish false-positive findings. This sparked a period of methodological reflection that we review here and call Psychology's Renaissance. We begin by describing how psychologists' concerns with publication bias shifted from worrying about file-drawered studies to worrying about p-hacked analyses. We then review the methodological changes that psychologists have proposed and, in some cases, embraced. In describing how the renaissance has unfolded, we attempt to describe different points of view fairly but not neutrally, so as to identify the most promising paths forward. In so doing, we champion disclosure and preregistration, express skepticism about most statistical solutions to publication bias, take positions on the analysis and interpretation of replication failures, and contend that meta-analytical thinking increases the prevalence of false positives. Our general thesis is that the scientific practices of experimental psychologists have improved dramatically.

  16. Diet and psychological health. (United States)

    Miller, M


    This article reviews research that suggests a relationship between diet and psychological symptoms. Mind-body dualism (as it relates to clinical practice) and the limited role of nutrition in mainstream biomedical training and treatment are discussed as background issues. Two areas of inquiry that have generated relevant research findings in this area are reviewed: (1) orthomolecular theory and vitamin deficiencies, and (2) clinical ecology/environmental medicine theory and the impact of "food allergies." Although clinical case reports and promising research findings have been reported, the impact of diet on psychological health is neither widely accepted nor integrated into mental health treatment methods. Ongoing research findings in brain biochemistry and psychoneuroimmunology point to communication pathways that can provide a clearer understanding of the links between nutritional intake, central nervous system and immune function, and psychological health status. These findings may lead to greater acceptance of dietary treatment approaches among health practitioners addressing psychological disorders.

  2. The Study of Faculty Productivity through Confirmatory Factor Analysis: the case of Psychology in United States of America

    Directory of Open Access Journals (Sweden)



    Full Text Available The article proposes the use of Confirmatory Factor Analysis techniques as a new approach to the measurement problem of faculty productivity. For this purpose, the author uses an analysis of scholarly productivity with data of 513 professors in the field of psychology in North America, between 1997 and 1998. Based on this analysis it is possible to identify three latent variables that describe the productivity of the sample: one factor that captures theinflation of all the observed variables, one factor that measures individual productivity and a factor that measures the joint productivity of faculty members. The findings suggest the need of novel approaches to policies for measurement and support of faculty productivity. These policies should be oriented not only to increase the productivity rates but also to decrease the probability of inflation.

  3. Private landowners and environmental conservation: a case study of social-psychological determinants of conservation program participation in Ontario

    Directory of Open Access Journals (Sweden)

    Michael Drescher


    Full Text Available Preservation of biodiversity and continued provision of ecosystem services increasingly relies on environmental conservation on private lands. Despite a multitude of past studies, our knowledge of the motives, opportunities, and challenges of private land conservation, especially on nonworking lands, where financial incentives are less relevant, remains incomplete. A key reason is that a variety of theoretical approaches, resulting in diverging study results, have been used to investigate private land conservation. To help remedy this problem, the current study rigorously examined several established social-psychological determinants of proenvironmental behaviors and developed a comprehensive model, which merged elements from previous studies, to investigate landowner participation in a government-sponsored private land conservation program for nonworking lands. The results are based on analysis of a mailed survey of 800 program-eligible landowners. Contrasting program participants with nonparticipants, we elicited information such as about values, worldviews, socio-demographic characteristics, and property attributes that led landowners to participate in this conservation program. The results of our study illustrate the complex relationships among values, worldviews, norms, attitudes, and behaviors emphasizing the importance of proenvironmental worldviews and of formal education for increasing the likelihood of enrollment in this government-sponsored private land conservation program. Against expectation, neither personal norms, household income, political leaning, nor the size of the eligible property area were found to be important in directly determining the decision to enroll in this conservation program. However, an association of political leaning with stated personal obligation for private land conservation was found. Our results highlight the relationship between formal education and achievement of private land conservation goals

  5. Public health foodborne illness case study during a Special Operations Forces deployment to South America. (United States)

    McCown, Michael; Grzeszak, Benjamin


    Although many public health articles have been published detailing foodborne illness outbreaks, a medical literature search revealed no articles that detail a case study or a specific response of a deployed U.S. military unit to a potential foodborne illness. This article describes a recent public health case study of a U.S. Special Operations Forces (SOF) team sickened while deployed to South America. It highlights public health factors which may affect U.S. personnel deployed or serving overseas and may serve as a guide for a deployed SOF medic to reference in response to a potential food- or waterborne illness outbreak. Eight food samples and five water samples were collected. The food samples were obtained from the host nation kitchen that provided food to the SOF team. The water samples were collected from the kitchen as well as from multiple sites on the host nation base. These samples were packaged in sterile containers, stored at appropriate temperatures, and submitted to a U.S. Army diagnostic laboratory for analysis. Laboratory results confirmed the presence of elevated aerobic plate counts (APCs) in the food prepared by the host nation and consumed by the SOF team. High APCs in food are the primary indicator of improper sanitation of food preparation surfaces and utensils. This case study concluded that poor kitchen sanitation, improper food storage, preparation, and/or holding were the probable conditions that led to the team?s symptoms. These results emphasize the importance of ensuring safe food and water for U.S. personnel serving overseas, especially in a deployment or combat setting. Contaminated food and/or water will negatively impact the health and availability of forces, which may lead to mission failure. The SOF medic must respond to potential outbreaks and be able to (1) critically inspect food preparation areas and accurately advise commanders in order to correct deficiencies and (2) perform food/water surveillance testing consistently

  6. Beliefs and values about intra-operative teaching and learning: a case study of surgical teachers and trainees. (United States)

    Ong, Caroline C P; Dodds, Agnes; Nestel, Debra


    Surgeons require advanced psychomotor skills, critical decision-making and teamwork skills. Much of surgical skills training involve progressive trainee participation in supervised operations where case variability, operating team interaction and environment affect learning, while surgical teachers face the key challenge of ensuring patient safety. Using a theoretical framework of situated learning including cognitive apprenticeship, we explored teachers' and trainees' beliefs and values about intra-operative training and reasons for any differences. A qualitative case study method was used where five teacher-trainee pairs participating in an observed teaching operation were separately interviewed about the same operation. Thematic analysis of transcribed interviews and observations was performed with iterative refinement and a reflexive approach was adopted throughout the study. We found that in all cases, teachers and trainees had shared recognition of learning about technical skills whereas they differed in three cases regarding non-technical skills such as surgical reasoning and team management. Factors contributing to teacher and trainee satisfaction with the process were successful trainee completion of operation without need for surgeon take-over, a positive learning environment and learning new things. Teaching-learning behaviours observed and discussed were modeling, coaching and scaffolding, while exploration, reflection and articulation were less common. Our study reveals differing teacher and trainee perspectives of some aspects of intra-operative training and surfaces new reasons other than amount of feedback and autonomy given. Factors contributing to different perspectives include teacher and trainee abilities, values and situational influences. Targeted teaching-learning strategies could enhance intra-operative learning.

  7. A case report of acampomelic campomelic dysplasia and operative difficulties in cleft palate reconstruction

    M Pasupathy


    Full Text Available Acampomelic campomelic dysplasia (CD is a type of CD (CD; OMIM #114290, a rare form of congenital short-limbed dwarfism and is due to mutations in SOX9 gene family. Characteristic phenotypes of CD include bowing of the lower limbs, a narrow thoracic cage, 11 pairs of ribs, hypoplastic scapulae, macrocephaly, flattened supraorbital ridges and nasal bridge, cleft palate and micrognathia. The bending of the long bones is not an obligatory feature and is absent in about 10% of cases, referred to as acampomelic CD. A child previously diagnosed with acampomelic CD was brought to our outpatient clinic for cleft palate reconstruction. Our neurosurgeon cautioned us against performing surgery with extension of the neck in view of the possibility of producing quadriparesis, due to narrowing of the spinal canal as part of the osseous anomaly noted in the magnetic resonance imaging study of the spine, thus making the anaesthesia, surgical and post-operative procedures difficult. The cleft palate reconstruction was performed with all precautions and was uneventful.

The case is made that scientific progress in psychology has been (and still is) impeded by prolonged misadventures down conceptual dead ends such as biological reductionism, the nature/nurture debate, evolutionary psychology, and the persistent insistence on emphasizing dependent variables that defy observation and measurement, such...

  10. Evaluating the effect of operative technique on leaks after laparoscopic sleeve gastrectomy: a case-control study. (United States)

    Varban, Oliver A; Sheetz, Kyle H; Cassidy, Ruth B; Stricklen, Amanda; Carlin, Arthur M; Dimick, Justin B; Finks, Jonathan F


    To assess the effect of operative technique on staple line leaks after laparoscopic sleeve gastrectomy (LSG). Staple-line leaks after LSG are a major source of morbidity and mortality. Variations in operative technique exist; however, their effect on leaks is poorly understood. We analyzed data from the Michigan Bariatric Surgery Collaborative (MBSC) to perform a case-control study comparing patients who had a clinically significant leak after undergoing a primary LSG to those who did not. A total of 45 patients with leaks were identified between January 2007 and December 2013. The leak group was matched 1:2 to a control group based on procedure type, age, body mass index, sex, and year the procedure was performed. Technique-specific factors were assessed by reviewing operative notes from all primary bariatric procedures in our study population. Conditional logistic regression was used to identify techniques associated with leaks. To increase the power of our analysis, we used a significance level of .10. Leak rates with LSG have decreased over the past 5 years (1.18% to .36%) as annual case volume has increased (846 cases/yr to 4435 cases/yr). Surgeons who performed 43 or more cases per year had a leak ratecases requiring a blood transfusion (26.2% versus 1.08%, P = .0031) and when cases were converted to open surgery (7.14% versus 0%, P = .0741). However, there was no significant difference in operative time between cases involving a leak and their matched controls (95.4 min versus 87.1 min, P = .1197). Oversewing of the staple line was the only technique associated with less leaks after controlling for confounding factors (OR .397 CI .174, .909, P = .0665). Notably, surgeons who oversewed routinely were also found to have higher case volume (307 versus 140, P = .0216) and less overall complication rates (4.81% versus 7.95%, P = .0027). Furthermore, oversewing technique varied widely as only 22.6% of cases involved oversewing of the entire staple line. Despite

  12. Mass media constructions of 'socio-psychological epidemics' in sub-Saharan Africa: The case of genital shrinking in 11 countries. (United States)

    de-Graft Aikins, Ama; Dzokoto, Vivian A; Yevak, Earl


    Genital shrinking is a recurring phenomenon with about 180 reported cases in sub-Saharan Africa over the last two decades. Transcending national boundaries, it results in distress for victims, mob violence against accused perpetrators and mass panic which law enforcement agencies struggle to contain. This article examines mass media construction and framing of genital shrinking within a social representations theory framework. Our analysis suggests the following: (1) mass media reports are informed by lay and expert perspectives; (2) three stocks of knowledge are drawn on interchangeably, with culture constituting a core representation; (3) lay and expert perspectives overlap on cultural and common-sense explanations of genital shrinking; and (4) scientific explanations are limited to individual pathophysiology and psychopathology and do not inform public opinion. We consider the implications of understanding genital shrinking for improving mass media constructions and dissemination of information on 'socio-psychological epidemics' that may have scientific explanations. © The Author(s) 2015.

  13. Modeling the operational risk in Iranian commercial banks: case study of a private bank (United States)

    Momen, Omid; Kimiagari, Alimohammad; Noorbakhsh, Eaman


    The Basel Committee on Banking Supervision from the Bank for International Settlement classifies banking risks into three main categories including credit risk, market risk, and operational risk. The focus of this study is on the operational risk measurement in Iranian banks. Therefore, issues arising when trying to implement operational risk models in Iran are discussed, and then, some solutions are recommended. Moreover, all steps of operational risk measurement based on Loss Distribution Approach with Iran's specific modifications are presented. We employed the approach of this study to model the operational risk of an Iranian private bank. The results are quite reasonable, comparing the scale of bank and other risk categories.

  14. Visualizing feasible operating ranges within tissue engineering systems using a "windows of operation" approach: a perfusion-scaffold bioreactor case study. (United States)

    McCoy, Ryan J; O'Brien, Fergal J


    Tissue engineering approaches to developing functional substitutes are often highly complex, multivariate systems where many aspects of the biomaterials, bio-regulatory factors or cell sources may be controlled in an effort to enhance tissue formation. Furthermore, success is based on multiple performance criteria reflecting both the quantity and quality of the tissue produced. Managing the trade-offs between different performance criteria is a challenge. A "windows of operation" tool that graphically represents feasible operating spaces to achieve user-defined levels of performance has previously been described by researchers in the bio-processing industry. This paper demonstrates the value of "windows of operation" to the tissue engineering field using a perfusion-scaffold bioreactor system as a case study. In our laboratory, perfusion bioreactor systems are utilized in the context of bone tissue engineering to enhance the osteogenic differentiation of cell-seeded scaffolds. A key challenge of such perfusion bioreactor systems is to maximize the induction of osteogenesis but minimize cell detachment from the scaffold. Two key operating variables that influence these performance criteria are the mean scaffold pore size and flow-rate. Using cyclooxygenase-2 and osteopontin gene expression levels as surrogate indicators of osteogenesis, we employed the "windows of operation" methodology to rapidly identify feasible operating ranges for the mean scaffold pore size and flow-rate that achieved user-defined levels of performance for cell detachment and differentiation. Incorporation of such tools into the tissue engineer's armory will hopefully yield a greater understanding of the highly complex systems used and help aid decision making in future translation of products from the bench top to the market place.

  16. Does working with child abuse cases affect professionals' parenting and the psychological well-being of their children? (United States)

    Dursun, Onur Burak; Sener, Mustafa Talip; Esin, Ibrahim Selcuk; Ançi, Yüksel; Yalin Sapmaz, Sermin


    Work in the field of sexual abuse is extremely stressful and may arouse negative personal reactions. Although these secondary trauma effects are well described on a personal level, there is not enough evidence to understand whether these professionals carry these effects to their homes, families, and offspring. This study aims to identify the effects of working with child abuse cases on the anxiety level and parenting styles of childhood trauma workers and on their children's well-being. A total of 43 health and legal system workers who worked with abused children in any step of their process and who had children constituted the study group, and 50 control cases, each working in the same institution and having the same occupation as 1 of the participants from the study group and having children but not working directly with children and child abuse cases, were included in the study. Participants were asked to fill out a sociodemographic form, the Parental Attitude Research Instrument, the trait portion of the State-Trait Anxiety Inventory, and an age-appropriate form of the Child Behavior Checklist for each child they had. Professionals in the study working with child abuse cases demonstrated significantly higher democratic parenting attitudes. Law enforcement workers working with child abuse cases demonstrated stricter and more authoritarian parenting strategies, as well as more democratic attitudes, than their colleagues. There was not a statistically significant relationship between child abuse workers' anxiety level and their children's well-being among control subjects.

    Directory of Open Access Journals (Sweden)

    Wever Jan


    Full Text Available Abstract Background Clinical characteristics and complications of Duchenne muscular dystrophy caused by skeletal and cardiac muscle degeneration are well known. Gastro-intestinal involvement has also been recognised in these patients. However an acute perforated gastro-duodenal peptic ulcer has not been documented up to now. Case presentation A 26-year-old male with Duchenne muscular dystrophy with a clinical and radiographic diagnosis of acute perforated gastro-duodenal peptic ulcer is treated non-operatively with naso-gastric suction and intravenous medication. Gastrointestinal involvement in Duchenne muscular dystrophy and therapeutic considerations in a high risk patient are discussed. Conclusion Non-surgical treatment for perforated gastro-duodenal peptic ulcer should be considered in high risk patients, as is the case in patients with Duchenne muscular dystrophy. Patients must be carefully observed and operated on if non-operative treatment is unsuccessful.

  2. Whither Psychology. (United States)

    Halpern, Diane F


    Contemporary psychology is experiencing tremendous growth in neuroscience, and there is every indication that it will continue to gain in popularity notwithstanding the scarcity of academic positions for newly minted Ph.Ds. Despite the general perception that brain correlates "explain" or "cause" the mind and behavior, these correlates have not yet proven useful in understanding psychological processes, although they offer the possibility of early identification of some disorders. Other recent developments in psychology include increased emphasis on applications and more global representation among researchers and participants. In thinking about the way we want psychology to evolve, psychologists need to pay more than lip service to the idea that complex questions in psychology require multiple levels of analysis with contributions from biological (brain, hormones, and genetics), individual differences and social and cultural perspectives. Early career psychologists who can attain a breadth of knowledge will be well-positioned for a team approach to psychological inquiry. Finally, I offer the belief that an emphasis on enhancing critical thinking skills at all levels of education offers the best hope for the future.

  3. Intra-operative predictors of postoperative Takotsubo syndrome in liver transplant recipients-An exploratory case-control study. (United States)

    Aniskevich, Stephen; Chadha, Ryan M; Peiris, Prith; Taner, Cemal Burcin; Torp, Klaus L; Thomas, Colleen S; Yataco, Maria L; Pai, Sher-Lu


    Takotsubo syndrome (TTS), also known as Takotsubo cardiomyopathy or stress-induced cardiomyopathy, has been described following a variety of surgeries and disease states. The relationship between intra-operative anesthesia management and the development of this syndrome has never been fully elucidated. The primary objective of this study was to determine the relationship of multiple intra-operative factors on the pathogenesis of TTS. A single-center retrospective review of all liver transplants performed at Mayo Clinic Florida from January 2005 to December 2014. Patients developing left ventricular dilation and a concomitant decrease in ejection fraction, a negative cardiac catheterization, or stress test within 30 days of transplantation were identified. Cases were matched 2:1 to controls with respect to MELD, age, sex, and indication for transplantation. Our evaluation included liver graft characteristics, intra-operative medications, and intra-operative hemodynamic measurements. We identified 24 cases of TTS from a pool of 1752 transplants, for an incidence of 1.4%. No statistically significant differences in intra-operative measures between the two groups were identified (all P ≥ .08). Our exploratory, single-center retrospective review evaluating 46 intra-operative characteristics found no association with the development of TTS. © 2017 John Wiley & Sons A/S.

    Complex and tightly coupled operations, despite having clear command lines and rigorous procedures, may be vulnerable to unexpected events that threaten their operations. To succeed, they need the capacity to respond flexibly and swiftly. In subsea operations, it has been proposed that when disruptive events occur while the formal leader is focused on task coordination, others with sufficient time, competence and standing step in and exercise informal leadership. This ...

This paper explores how this decoupling thinking can be applied in service operations and in particular in health care. It first reviews the relevant literature on decoupling fundamentals, the front- and back-office distinction, and new emerging decoupling thinking in service operations. Subsequently, a flow-based framework including content and process is develo...

  9. Short and longer-term psychological consequences of Operation Cast Lead: documentation from a mental health program in the Gaza Strip

    Directory of Open Access Journals (Sweden)

    Llosa Augusto E


    Full Text Available Abstract Background There is growing recognition of the psychological impact of adversity associated with armed conflict on exposed civilian populations. Yet there is a paucity of evidence on the value of mental health programs in these contexts, and of the chronology of psychological sequelae, especially in prolonged conflicts with repeated cycles of extreme violence. Here, we describe changes in the psychological profile of new patients in a mental health program after the military offensive Cast Lead, in the context of the prolonged armed conflict involving the Gaza Strip. Methods This study analyses routinely collected program data from a Médecins Sans Frontières mental health program in the Gaza Strip spanning 2007–2011. Data consist of socio-demographic as well as clinical baseline and follow-up data on new patients entering the program. Comparisons were made through Chi square and Fisher’s exact tests, univariate and multivariate logistic and linear regression. Results PTSD, depression and other anxiety disorders were the most frequent psychopathologies, with 21% having multiple diagnoses. With a median of nine sessions, clinical improvement was recorded for 83% (1122/1357, and more common for those with separation anxiety, acute and posttraumatic disorders as principal diagnosis (855/1005, compared to depression (141/183, p Conclusion Evolving changes in patient volume, diagnoses and recall period to triggering events suggest a lengthy and durable effect of an intensified exposure to violence in a context of prolonged conflict. Our findings suggest that mental health related humanitarian relief in protracted conflicts might need to prepare for an increase in patients with changing profiles over an extended period following an acute flare-up in violence.

  13. 15-year follow-up of a case of amelogenesis imperfecta: importance of psychological aspect and impact on quality of life. (United States)

    Trentesaux, T; Rousset, M M; Dehaynin, E; Laumaillé, M; Delfosse, C


    Amelogenesis imperfecta (AI) represents a group of hereditary conditions which affects enamel formation in the primary and permanent dentitions. Gene mutations alter the quality and/or quantity of enamel. AI often has severe consequences for the patient such as high tooth sensitivity, low aesthetic quality of the dentition, and poor mechanical properties of the dental tissues. This can result in reduced oral health-related quality of life. We present the case of a child affected by AI which had been diagnosed at the age of 9 years. Teeth presented many enamel defects. The patient presented thin brown to yellow enamel and the surface was rough and granular. He revealed short clinical crowns, occlusal wear with exposed dentine in posterior areas. He also presented a lateral open bite and lingual lateral interposition due to partial destruction of deciduous molars. Panoramic radiograph showed no differences between enamel and dentine appearance and also coronary destruction of permanent molars. The initial treatment consisted of adaptation of composite resins on permanent incisors to improve aesthetics. Preformed metal crowns were placed on first permanent molars to prevent their premature destruction. This was disrupted for a variety of reasons. Fourteen years later, after a dental nomadism, the patient consulted by chance a dentist who identified his genetic pathology and was aware of its consequences. Extensive prosthodontic treatment was needed, but oral hygiene was poor and gingivitis remained. Dealing with high loss of motivation has been one of the main challenges because this patient had a lot of psychological problems. He was concerned, as are many patients affected by AI or other enamel abnormalities. This paper highlights the difficulties of long-term care of this dental abnormality. Psychological aspects of the quality of life, which is a common feature in patients suffering from many kinds of enamel anomalies, are very important.

  14. [Maternity in adolescence: obstetrical analysis and review of the influence of cultural, socioeconomic and psychological factors in a retrospective study of 62 cases]. (United States)

    Faucher, P; Dappe, S; Madelenat, P


    To analyse obstetrical outcome of teenage pregnancies and conditions of discharge from the maternity ward. A retrospective study of 62 deliveries of women 13 to 17 years old, between 1997 and 2000. A majority of patients is aged 16 or 17 (92%); 46.8% of teenagers were born in a sub-Saharan African country. The teenagers do not go to school in 45.2% of the cases. The first visit to hospital is late in the pregnancy (40.3% had their first visit after 30 weeks of amenorrhoea). There was no follow-up at all for 17.7% of the pregnancies. The obstetrical outcome is normal in 66.2% of the cases; 93.5% of the children were born after 37 SA and had a normal weight for gestational age; 93.5% were discharged from the maternity ward with their children. A specific follow-up took place for 36.2% of the women. Compared with women from other origins, teenagers born in sub-Saharan Africa more often live with their boyfriend (P = 0.03), who is likely to be over 25 (P = 0.001). Sub-Saharan African women more often return and live at the father's home (P maternity hospital and to provide economical and psychological support during and after pregnancy.

  15. Psychological Spacetime

    Directory of Open Access Journals (Sweden)

    Lucian Gideon Conway


    Full Text Available It has been an accepted scientific fact in physics for almost 100 years that time speeds up and slows down for an observer based on factors—such as motion and gravity—that affect space. Yet this fact, drawn from the theory of relativity, has not been widely integrated into the study of the psychology of time. The present article helps to fill in this gap between physics and psychology by reviewing evidence concerning what a psychological spacetime processor—one that accounted for the theory of relativity’s empirically validated predictions of the compensatory relationship between time and space—would look like. This model of the spacetime processor suggests that humans should have a psychological mechanism for slowing time down as motion speeds up, a prediction that already has widespread research support. We also discuss several novel hypotheses directly suggested by the spacetime model and a set of related speculations that emerge when considering spacetime (some of which have already received empirical support. Finally, we compare and contrast three very different potential reasons why we might have developed a spacetime processor in the first place. We conclude that the spacetime model shows promise for organizing existing data on time perception and generating novel hypotheses for researchers to pursue. Considering how humans might process spacetime helps reduce the existing gap between our understanding of physics and our understanding of human psychology.

  16. Political psychology. (United States)

    Stone, Susanna; Johnson, Kate M; Beall, Erica; Meindl, Peter; Smith, Benjamin; Graham, Jesse


    Political psychology is a dynamic field of research that offers a unique blend of approaches and methods in the social and cognitive sciences. Political psychologists explore the interactions between macrolevel political structures and microlevel factors such as decision-making processes, motivations, and perceptions. In this article, we provide a broad overview of the field, beginning with a brief history of political psychology research and a summary of the primary methodological approaches in the field. We then give a more detailed account of research on ideology and social justice, two topics experiencing a resurgence of interest in current political psychology. Finally, we cover research on political persuasion and voting behavior. By summarizing these major areas of political psychology research, we hope to highlight the wide variety of theoretical and methodological approaches of cognitive scientists working at the intersection of psychology and political science.

  17. Conceptual Model Development of Sustainability Practices: The Case of Port Operations for Collaboration and Governance

    Directory of Open Access Journals (Sweden)

    Dalwon Kang


    Full Text Available Sustainability practices in port operations are critical issue to achieve port sustainability involving economic, social and environmental issues. To assist ports to successfully implant sustainability practices into their operations, this paper conceptualized the structure of sustainability practices in international port operations, by clustering the relevant issues, empirically. Using 203 samples collected from port stakeholders in the major ports in Northeast Asia, multi-measurement items were analyzed on exploratory factor analysis in SPSS 21. Results generated a structure that consists of five sub-dimensions conceptualizing sustainability practices in the context of port operations. As operative practices to accommodate current and future demands in a port, the five-factor model clustering the relevant issues incorporate environmental technologies, process and quality improvement, monitoring and upgrading, communication and cooperation, and active participation. Providing useful insights for strategic agenda to assist ports to incorporate sustainability practices in their operations, the five-factor model offer both a descriptive and diagnostic management tool for future improvement in port operations.

  18. Environmental Impacts of Metal Cladding Operations and Remedial Measures: A Case Study (United States)

    Roy, P. P.; Sawmliana, C.; Singh, R. K.


    In metal cladding operations, a mixture of 11 % TNT flakes, 44 % ammonium nitrate (non-explosive) and 45 % dehydrated salt (non-explosive) are mixed uniformly to produce an explosive mixture with velocity of detonation 1,800-2,000 m/s. To study the environmental impacts of such operations which led to serious complaints from neighbouring villagers and even closure of some units, a study was carried out to investigate the levels of ground vibration, air overpressure and noise generated by blasting operations of different explosive charge quantities during the metal cladding operations and their impacts on the surrounding villages. Following the safety norms of Central Pollution Control Board (CPCB, Model Rules of the Factories Act on Noise Pollution Control) [1] and Directorate General of Mines Safety (DGMS, Damage to the structures due to blast induced ground vibration in the mining areas) [2] of India, generalised guidelines for such safe operations were framed. This paper describes the operational aspects of metal cladding, experimental results and scientific analyses of data to propose certain guidelines for safe metal cladding operations.

  19. Green's function asymptotics near the internal edges of spectra of periodic elliptic operators. Spectral edge case

    KAUST Repository

    Kuchment, Peter


    Precise asymptotics known for the Green\\'s function of the Laplace operator have found their analogs for periodic elliptic operators of the second order at and below the bottom of the spectrum. Due to the band-gap structure of the spectra of such operators, the question arises whether similar results can be obtained near or at the edges of spectral gaps. As the result of this work shows, this is possible at a spectral edge when the dimension d ≥ 3. © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  20. The Bloch wave operator: generalizations and applications: II. The time-dependent case

    Energy Technology Data Exchange (ETDEWEB)

    Jolicard, Georges [Observatoire de Besancon (UMR-CNRS 6091), Universite de Franche-Comte, 41 bis, Avenue de l' Observatoire, 25000 Besancon (France); Killingbeck, John P [Observatoire de Besancon (UMR-CNRS 6091), Universite de Franche-Comte, 41 bis, Avenue de l' Observatoire, 25000 Besancon (France); Mathematics Department, University of Hull, Hull HU6 7RX (United Kingdom)


    Part II of the review shows how the stationary Bloch wave operator of part I can be suitably modified to give a time-dependent wave operator. This operator makes it possible to use a relatively small active space in order to describe the dynamical processes which occur in quantum mechanical systems which have a time-dependent Hamiltonian. A close study is made of the links between the time-dependent and time-independent wave operators at the adiabatic limit; the analysis clarifies the way in which the wave operator formalism allows the time evolution of a system or a wave packet to be described in terms of a fast evolution inside the active space together with weak transitions out of this space which can be treated by perturbation methods. Two alternative wave operator equations of motion are derived and analysed. The first one is a non-linear differential equation in the usual Hilbert space; the second one is a differential equation in an extended Hilbert space with an extra time variable added and becomes equivalent to the usual Bloch equation when the Floquet Hamiltonian is taken in place of the ordinary Hamiltonian. A study is made of the close relationships between the time-dependent wave operator formalism, the Floquet theory and the (t, t') theory. Some original methods of solution of the two forms of wave operator equation are proposed and lead to new techniques of integration for the time-dependent Schroedinger equation (e.g., the generalized Green equation procedure). Mixed procedures involving both the time-independent and time-dependent wave operators are shown to be applicable to the internal eigenstate problem for large complex matrices. A detailed account is given of the description of inelastic and photoreactive processes by means of the time-dependent wave operator formalism, with particular attention to laser-molecule interactions. The emphasis is on projection operator techniques, with special attention being given to the method of selection

In particular, I found an incidence labelled ‘psychological IVF’ theoretically provocative as it challenged my views on materializations, which I was preparing to study. This paper centres on the story...... of psychological IVF, and I use this narrative to consider emotions and materialization methodologically. I also ask how emotions at fertility clinics can be conceptualized to enable analysis of their materialization, change, and effects. In order to do so, I develop the term ‘emotional choreography......’. This theoretical work has three aims. First, it seeks to illustrate how the story of psychological IVF offers a rich range of materializations of emotions. Secondly, this work proposes a feminist materialist conceptualization of emotions that is both non-representational and posthuman. This conceptualization draws...

  3. Towards building equitable health systems in Sub-Saharan Africa: lessons from case studies on operational research

    Directory of Open Access Journals (Sweden)

    Tolhurst Rachel


    Full Text Available Abstract Background Published practical examples of how to bridge gaps between research, policy and practice in health systems research in Sub Saharan Africa are scarce. The aim of our study was to use a case study approach to analyse how and why different operational health research projects in Africa have contributed to health systems strengthening and promoted equity in health service provision. Methods Using case studies we have collated and analysed practical examples of operational research projects on health in Sub-Saharan Africa which demonstrate how the links between research, policy and action can be strengthened to build effective and pro-poor health systems. To ensure rigour, we selected the case studies using pre-defined criteria, mapped their characteristics systematically using a case study development framework, and analysed the research impact process of each case study using the RAPID framework for research-policy links. This process enabled analysis of common themes, successes and weaknesses. Results 3 operational research projects met our case study criteria: HIV counselling and testing services in Kenya; provision of TB services in grocery stores in Malawi; and community diagnostics for anaemia, TB and malaria in Nigeria. Political context and external influences: in each case study context there was a need for new knowledge and approaches to meet policy requirements for equitable service delivery. Collaboration between researchers and key policy players began at the inception of operational research cycles. Links: critical in these operational research projects was the development of partnerships for capacity building to support new services or new players in service delivery. Evidence: evidence was used to promote policy dialogue around equity in different ways throughout the research cycle, such as in determining the topic area and in development of indicators. Conclusion Building equitable health systems means

  4. Holocaust and strategic bombing: case studies in the psychology, organization, and technology of mass killing in the twentieth century

    Energy Technology Data Exchange (ETDEWEB)

    Markusen, E.R.


    After preliminary discussion of the unprecedented scale of mass killing in the twentieth century, the threat of nuclear war, and the widespread neglect of these issues, the literature on two major types of government sanctioned mass killing is reviewed; genocide, in which a government slaughters its own citizens or subjects, and total war, in which two or more governments slaughter each other's civilian citizens or subjects. This literature review reaches two basic conclusions: (1) there is considerable inconsistency and ambiguity among definitions of genocide and total war; and (2) there is a controversy regarding how distinct or similar the two forms of mass killing actually are. A comparative historical analysis was undertaken in which the Nazi Holocaust was selected as an example of genocide, and the Allied strategic bombing campaigns during World War II were selected to exemplify total war. The two cases are compared in terms of a conceptual framework of five hypothesized facilitating factors. On the basis of this comparative analysis, four or the five hypothesized facilitating factors are found to have played important roles in both cases. The findings of the study are discussed, and their implications for the threat of nuclear holocaust are explored.

  5. Working with a fixed operating room team on consecutive similar cases and the effect on case duration and turnover time. (United States)

    Stepaniak, Pieter S; Vrijland, Wietske W; de Quelerij, Marcel; de Vries, Guus; Heij, Christiaan


    If variation in procedure times could be controlled or better predicted, the cost of surgeries could be reduced through improved scheduling of surgical resources. This study on the impact of similar consecutive cases on the turnover, surgical, and procedure times tests the perception that repeating the same manual tasks reduces the duration of these tasks. We hypothesize that when a fixed team works on similar consecutive cases the result will be shorter turnover and procedure duration as well as less variation as compared with the situation without a fixed team. Case-control study. St Franciscus Hospital, a large general teaching hospital in Rotterdam, the Netherlands. Two procedures, inguinal hernia repair and laparoscopic cholecystectomy, were selected and divided across a control group and a study group. Patients were randomly assigned to the study or control group. Preparation time, surgical time, procedure time, and turnover time. For inguinal hernia repair, we found a significantly lower preparation time and 10 minutes less procedure time in the study group, as compared with the control group. Variation in the study group was lower, as compared with the control group. For laparoscopic cholecystectomy, preparation time was significantly lower in the study group, as compared with the control group. For both procedures, there was a significant decrease in turnover time. Scheduling similar consecutive cases and performing with a fixed team results in lower turnover times and preparation times. The procedure time of the inguinal hernia repair decreased significantly and has practical scheduling implications. For more complex surgery, like laparoscopic cholecystectomy, there is no effect on procedure time.

  7. Positive Psychology and Disaster Mental Health: Strategies for Working with Children and Adolescents. (United States)

    Vernberg, Eric M; Hambrick, Erin P; Cho, Bridget; Hendrickson, Michelle L


    Positive psychology concepts and principles can be incorporated into preparedness, crisis response, and recovery phases of disaster mental health efforts to address the needs of children, adolescents, and families. This article articulates general developmental considerations for applying positive psychology in disaster mental health contexts and discusses how 5 essential elements of immediate and midterm mass trauma intervention identified by Hobfoll et al. (2007) may be infused in applications of positive psychology for children and adolescents. Specific strategies for working with children, adolescents, and their families in home, community, and school contexts are drawn in part from disaster mental health resources developed jointly by the National Child Traumatic Stress Network and National Center for Posttraumatic Stress Disorder, including the Psychological First Aid Field Operations Guide (Brymer et al., 2006), the Skills for Psychological Recovery Field Operations Guide (Berkowitz et al., 2010), and the Psychological First Aid for Schools Field Operations Manual (Brymer et al., 2012).

  13. Barrier and operational risk analysis of hydrocarbon releases (BORA-Release). Part II: Results from a case study. (United States)

    Sklet, Snorre; Vinnem, Jan Erik; Aven, Terje


    This paper presents results from a case study carried out on an offshore oil and gas production platform with the purpose to apply and test BORA-Release, a method for barrier and operational risk analysis of hydrocarbon releases. A description of the BORA-Release method is given in Part I of the paper. BORA-Release is applied to express the platform specific hydrocarbon release frequencies for three release scenarios for selected systems and activities on the platform. The case study demonstrated that the BORA-Release method is a useful tool for analysing the effect on the release frequency of safety barriers introduced to prevent hydrocarbon releases, and to study the effect on the barrier performance of platform specific conditions of technical, human, operational, and organisational risk influencing factors (RIFs). BORA-Release may also be used to analyse the effect on the release frequency of risk reducing measures.

  15. Clinically speaking, psychological abuse matters. (United States)

    Começanha, Rita; Basto-Pereira, Miguel; Maia, Ângela


    The adverse effects of intimate partner violence (IPV) on mental health are well-established, except in the cases of psychological abuse and men's victimization. This research study examines the prevalence and the independent contribution of psychological IPV on mental health for both genders. The initial sample comprises 661 college students from a Portuguese public university, who completed an e-survey. Statistical analysis focused on a subsample (n=364), 23% of which were men, after removing cases of physical and/or sexual abuse. A total of 75% of men and 72% of women reported lifetime psychological victimization and no differences were found for sociodemographic factors, including gender. However, women reported significantly more instigations of psychological abusive acts (OR =5.41, 95% CI=1.88-15.55). Multivariate linear regression models revealed that post-traumatic stress symptoms-PTSS (β=.51; p<.001), depression (β=.34; p<.001) and anxiety (β=.22; p<.001)-were predicted by psychological IPV. The strongest relationship was established between psychological IPV and PTSS, and the final model accounts for 28.6% of the variance (F(6357)=23.86, p<.001). This article provides an empirical basis to recognize the unique and serious impact of psychological IPV on mental health, and recommends screening psychological IPV as part of the clinical routine, developing a gender-inclusive approach, and implementing evidence-based protocols tailored to the needs of these victims.

    Brinkman, Justus-Martijn; Oddens, Jorg R; Van Royen, Barend J; Wever, Jan; Olsman, Jan G


    Clinical characteristics and complications of Duchenne muscular dystrophy caused by skeletal and cardiac muscle degeneration are well known. Gastro-intestinal involvement has also been recognised in these patients. However an acute perforated gastro-duodenal peptic ulcer has not been documented up to now. A 26-year-old male with Duchenne muscular dystrophy with a clinical and radiographic diagnosis of acute perforated gastro-duodenal peptic ulcer is treated non-operatively with naso-gastric suction and intravenous medication. Gastrointestinal involvement in Duchenne muscular dystrophy and therapeutic considerations in a high risk patient are discussed. Non-surgical treatment for perforated gastro-duodenal peptic ulcer should be considered in high risk patients, as is the case in patients with Duchenne muscular dystrophy. Patients must be carefully observed and operated on if non-operative treatment is unsuccessful.

  17. Business Ethics of Tour Operators – The Case Study of TUI

    Directory of Open Access Journals (Sweden)

    Marija Šuleić


    Full Text Available A large number of participants in tourism, both in offer and in demand, has conditioned the need for the creation ethical codices based on legislative regulations and moral principles. Among central figures in tourism, there are travel agencies and tour operators, the intermediaries between service providers and service users, in other words, passengers. The tour operators who are engaged in initiating tourism provide the services on foreign markets and tend to adapt their business to the laws and customs of the countries in which they run a business. TUI, as a leading European tour operator, which has even its representation in Serbia, can be a good example of the implementation of its business codes of ethics, but also adapting to the business customs being valid in the country in which TUI operates. Because of this, the aim of this work was to examine under what ethical standards TUI operates in Serbia in the domain of different stakeholders. The results of the research can be useful for different stakeholders.

  20. Operating procedures -- Preliminary results of a Safety and Environmental Management Program (SEMP) case study sponsored by the DOE and MMS

    Energy Technology Data Exchange (ETDEWEB)

    Bresler, R.A.; Tibbetts, O.D.; Antz, G.W. Von


    One June 30, 1994, the MMS published a Federal Register notice requesting that industry voluntarily adopt API RP 75 (SEMP). Under the SEMP program, offshore producers would be responsible for identifying potential hazards in the design, construction and operation of drilling and production platforms and developing specific approaches to reduce the occurrence of accidents. Many smaller and mid-size independent producers have raised questions over the costs and methods for implementing SEMP. The DOE and MMS determined that a carefully documented case study would answer many of the producers` questions. The results of the study would be oriented specifically to small- and mid-size companies, so independent producers would be much more willing to invest the time and resources to adapt the RP 75 procedures to their own operations. As a result, the DOE and MMS have entered into a 30-month study with Taylor Energy Company (TEC) and Paragon Engineering Services (Paragon) to develop a Safety and Environmental Management Plan (SEMP). This program is intended to demonstrate how small- to mid-size companies can effectively and inexpensively develop a SEMP in accordance with API RP 75. This paper will discuss the preliminary findings associated with the Taylor Energy Company/DOE SEMP case study. Specifically, the development of operating procedures which meet the intent and spirit of SEMP without the traditional high cost typically associated with engineered operations manuals is discussed.

  2. Operational river discharge forecasting in poorly gauged basins: the Kavango River basin case study

    DEFF Research Database (Denmark)

    Bauer-Gottwein, Peter; Jensen, Iris Hedegaard; Guzinski, R.


    Operational probabilistic forecasts of river discharge are essential for effective water resources management. Many studies have addressed this topic using different approaches ranging from purely statistical black-box approaches to physically based and distributed modeling schemes employing data...... in Africa. We present an operational probabilistic forecasting approach which uses public-domain climate forcing data and a hydrologic-hydrodynamic model which is entirely based on open-source software. Data assimilation techniques are used to inform the forecasts with the latest available observations....... Forecasts are produced in real time for lead times of 0-7 days. The operational probabilistic forecasts are evaluated using a selection of performance statistics and indicators and the performance is compared to persistence and climatology benchmarks. The forecasting system delivers useful forecasts...

  3. It's Just (Academic) Business: A Use Case in Improving Informatics Operations with Business Intelligence. (United States)

    McIntosh, Leslie D; Zabarovskaya, Connie; Uhlmansiek, Mary


    Academic biomedical informatics cores are beholden to funding agencies, institutional administration, collaborating researchers, and external agencies for ongoing funding and support. Services provided and translational research outcomes are increasingly important to monitor, report and analyze, to demonstrate value provided to the organization and the greater scientific community. Thus, informatics operations are also business operations. As such, adopting business intelligence practices offers an opportunity to improve the efficiency of evaluation efforts while fulfilling reporting requirements. Organizing informatics development documentation, service requests, and work performed with adaptable tools have greatly facilitated these and related business activities within our informatics center. Through the identification and measurement of key performance indicators, informatics objectives and results are now quickly and nimbly assessed using dashboards. Acceptance of the informatics operation as a business venture and the adoption of business intelligence strategies has allowed for data-driven decision making, faster corrective action, and greater transparency for interested stakeholders.

  6. Planning for avian flu disruptions on global operations: a DMAIC case study. (United States)

    Kumar, Sameer


    The author aims to assess the spread of avian flu, its impact on businesses operating in the USA and overseas, and the measures required for corporate preparedness. Six Sigma DMAIC process is used to analyze avian flu's impact and how an epidemic could affect large US business operations worldwide. Wal-Mart and Dell Computers were chosen as one specializes in retail and the other manufacturing. The study identifies avian flu pandemic risks including failure modes on Wal-Mart and Dell Computers global operations. It reveals the factors that reinforce avian-flu pandemic's negative impact on company global supply chains. It also uncovers factors that balance avian-flu pandemic's impact on their global supply chains. Avian flu and its irregularity affect the research outcomes because its spread could fluctuate based on so many factors that could come into play. Further, the potential cost to manufacturers and other supply chain partners is relatively unknown. As a relatively new phenomenon, quantitative data were not available to determine immediate costs. In this decade, the avian influenza H5N1 virus has killed millions of poultry in Asia, Europe and Africa. This flu strain can infect and kill humans who come into contact with this virus. An avian influenza H5N1 outbreak could lead to a devastating effect on global food supply, business services and business operations. The study provides guidance on what global business operation managers can do to prepare for such events, as well as how avian flu progression to a pandemic can disrupt such operations. This study raises awareness about avian flu's impact on businesses and humans and also highlights the need to create contingency plans for corporate preparedness to avoid incurring losses.

  2. The natural history of clinical operational tolerance after kidney transplantation through twenty-seven cases. (United States)

    Brouard, S; Pallier, A; Renaudin, K; Foucher, Y; Danger, R; Devys, A; Cesbron, A; Guillot-Guegen, C; Ashton-Chess, J; Le Roux, S; Harb, J; Roussey, G; Subra, J-F; Villemain, F; Legendre, C; Bemelman, F J; Orlando, G; Garnier, A; Jambon, H; Le Monies De Sagazan, H; Braun, L; Noël, C; Pillebout, E; Moal, M-C; Cantarell, C; Hoitsma, A; Ranbant, M; Testa, A; Soulillou, J-P; Giral, M


    We report here on a European cohort of 27 kidney transplant recipients displaying operational tolerance, compared to two cohorts of matched kidney transplant recipients under immunosuppression and patients who stopped immunosuppressive drugs and presented with rejection. We report that a lower proportion of operationally tolerant patients received induction therapy (52% without induction therapy vs. 78.3%[p = 0.0455] and 96.7%[p = 0.0001], respectively), a difference likely due to the higher proportion (18.5%) of HLA matched recipients in the tolerant cohort. These patients were also significantly older at the time of transplantation (p = 0.0211) and immunosuppression withdrawal (p = 0.0002) than recipients who rejected their graft after weaning. Finally, these patients were at lower risk of infectious disease. Among the 27 patients defined as operationally tolerant at the time of inclusion, 19 still display stable graft function (mean 9 ± 4 years after transplantation) whereas 30% presented slow deterioration of graft function. Six of these patients tested positive for pre-graft anti-HLA antibodies. Biopsy histology studies revealed an active immunologically driven mechanism for half of them, associated with DSA in the absence of C4d. This study suggests that operational tolerance can persist as a robust phenomenon, although eventual graft loss does occur in some patients, particularly in the setting of donor-specific alloantibody. © Copyright 2012 The American Society of Transplantation and the American Society of Transplant Surgeons.

  6. Probabilistic-Multiobjective Comparison of User-Defined Operating Rules. Case Study: Hydropower Dam in Spain

    Directory of Open Access Journals (Sweden)

    Paola Bianucci


    Full Text Available A useful tool is proposed in this paper to assist dam managers in comparing and selecting suitable operating rules. This procedure is based on well-known multiobjective and probabilistic methodologies, which were jointly applied here to assess and compare flood control strategies in hydropower reservoirs. The procedure consisted of evaluating the operating rules’ performance using a simulation fed by a representative and sufficiently large flood event series. These flood events were obtained from a synthetic rainfall series stochastically generated by using the RainSimV3 model coupled with a deterministic hydrological model. The performance of the assessed strategies was characterized using probabilistic variables. Finally, evaluation and comparison were conducted by analyzing objective functions which synthesize different aspects of the rules’ performance. These objectives were probabilistically defined in terms of risk and expected values. To assess the applicability and flexibility of the tool, it was implemented in a hydropower dam located in Galicia (Northern Spain. This procedure allowed alternative operating rule to be derived which provided a reasonable trade-off between dam safety, flood control, operability and energy production.

  7. Impact of employment status and work-related factors on risk of completed suicide. A case-control psychological autopsy study. (United States)

    Schneider, Barbara; Grebner, Kristin; Schnabel, Axel; Hampel, Harald; Georgi, Klaus; Seidler, Andreas


    The objective of this study was to determine the impact of work-related factors on risk for completed suicide. Psychiatric disorders and socio-demographic factors including work-related factors were assessed by a semi-structured interview using the psychological autopsy method in 163 completed suicide cases and by personal interview in 396 living population-based control persons. Unemployment (in particular, for more than six months), (early) retirement, or homemaker status were associated with highly significantly increased suicide risk, independently of categorized psychiatric diagnosis. In addition, adverse psychosocial working conditions, such as monotonous work, increased responsibility and pronounced mental strain due to contact with work clients, significantly increased suicide risk as well, again independently of categorized psychiatric diagnosis. These findings demonstrate that negative consequences of unemployment, homemaker status with no outside occupation, or (early) retirement, as well as adverse psychosocial working conditions, present relevant risk factors contributing to suicidal behavior, independently of diagnosed psychiatric disorders. Employment and a positive modification of working conditions, may possibly be preventive to important adverse mental health outcomes, including suicidality. Copyright © 2011 Elsevier Ltd.

  8. [A Case of Metastasis to the Base of the Skull after Rectal Cancer Operation with Symptom Management via Radiotherapy]. (United States)

    Sasaki, Megumi; Ishikawa, Toshiaki; Yamauchi, Shinichi; Orita, Fukuichiro; Miura, Tomiyuki; Tokura, Michiyo; Hanaoka, Marie; Kikuchi, Akifumi; Ishiguro, Megumi; Yasuno, Masamichi; Uetake, Hiroyuki


    In 2009, A 67-year-old woman underwent high anterior resection for rectal cancer(RS, type 2, pT3, pN1, cM0, pStage III a). U FT/LV was administered for 6 months as adjuvant chemotherapy after the operation. Because peritoneum dissemination and pelvic lymph node metastasis developed 9 months after the operation, CapeOX plus Bmab therapy was started, and we monitored the cancer partial response for the next 6 years. Six years and 9 months after the operation, we detected metastasis to the sacrum; thus, radiotherapy was started. Seven years after the first operation, we detected pulmonary, liver, distant lymph node, and subcutaneous metastasis. Additionally, in the next month, she complained of double vision and dysarthria, and metastasis to the base of the skull was diagnosed via head MRI scanning. We started radiotherapy, and the symptoms gradually improved. Although we started IRIS plus Bmab therapy for pulmonary, liver, distant lymph node, and subcutaneous metastasis, it became a progressive disease(PD). She passed away 7 years and 6 months after the first operation. In this case, radiotherapy was useful for symptom management of metastasis to the base of the skull after surgery for rectal cancer, which is an extremely rare occurrence.

  9. Evaluating National Weather Service Seasonal Forecast Products in Reservoir Operation Case Studies (United States)

    Nielson, A.; Guihan, R.; Polebistki, A.; Palmer, R. N.; Werner, K.; Wood, A. W.


    Forecasts of future weather and streamflow can provide valuable information for reservoir operations and water management. A challenge confronting reservoir operators today is how to incorporate both climate and streamflow products into their operations and which of these forecast products are most informative and useful for optimized water management. This study incorporates several reforecast products provided by the Colorado Basin River Forecast Center (CBRFC) which allows a complete retrospective analysis of climate forecasts, resulting in an evaluation of each product's skill in the context of water resources management. The accuracy and value of forecasts generated from the Climate Forecast System version 2 (CFSv2) are compared to the accuracy and value of using an Ensemble Streamflow Predictions (ESP) approach. Using the CFSv2 may offer more insight when responding to climate driven extremes than the ESP approach because the CFSv2 incorporates a fully coupled climate model into its forecasts rather than using all of the historic climate record as being equally probable. The role of forecast updating frequency will also be explored. Decision support systems (DSS) for both Salt Lake City Parley's System and the Snohomish County Public Utility Department's (SnoPUD) Jackson project will be used to illustrate the utility of forecasts. Both DSS include a coupled simulation and optimization model that will incorporate system constraints, operating policies, and environmental flow requirements. To determine the value of the reforecast products, performance metrics meaningful to the managers of each system are to be identified and quantified. Without such metrics and awareness of seasonal operational nuances, it is difficult to identify forecast improvements in meaningful ways. These metrics of system performance are compared using the different forecast products to evaluate the potential benefits of using CFSv2 seasonal forecasts in systems decision making.



  11. Team spirit makes the difference: the interactive effects of team work engagement and organizational constraints during a military operation on psychological outcomes afterwards. (United States)

    Boermans, S M; Kamphuis, W; Delahaij, R; van den Berg, C; Euwema, M C


    This article prospectively explores the effects of collective team work engagement and organizational constraints during military deployment on individual-level psychological outcomes afterwards. Participants were 971 Dutch peacekeepers within 93 teams who were deployed between the end of 2008 and beginning of 2010, for an average of 4 months, in the International Security Assistance Force. Surveys were administered 2 months into deployment and 6 months afterwards. Multi-level regression analyses demonstrated that team work engagement during deployment moderated the relation between organizational constraints and post-deployment fatigue symptoms. Team members reported less fatigue symptoms after deployment if they were part of highly engaged teams during deployment, particularly when concerns about organizational constraints during deployment were high. In contrast, low team work engagement was related to more fatigue symptoms, particularly when concerns about organizational constraints were high. Contrary to expectations, no effects for team work engagement or organizational constraints were found for post-traumatic growth. The present study highlights that investing in team work engagement is important for those working in highly demanding jobs. © 2014 John Wiley & Sons, Ltd.

  12. Intrapartum transperineal ultrasound used to predict cases of complicated operative (vacuum and forceps) deliveries in nulliparous women. (United States)

    Sainz, José A; García-Mejido, José A; Aquise, Adriana; Bonomi, María J; Borrero, Carlota; De La Fuente, Paloma; Fernández-Palacín, Ana


    The objective of this study was to investigate the predictive value of intrapartum transperineal ultrasound in the identification of complicated operative (vacuum or forceps) deliveries in nulliparous women. Prospective observational study of nulliparous women with an indication for operative delivery who underwent intrapartum transperineal ultrasound before fetal extraction. Managing obstetricians were blinded to the ultrasound data. Intrapartum transperineal ultrasound was performed immediately before blade application, both at rest and concurrently with contractions and active pushing. Operative delivery was classified as complicated when one or more of the following situations occurred: three or more tractions; a third-/fourth-degree perineal tear; significant bleeding during the episiotomy repair; major tear or significant traumatic neonatal lesion. A total of 143 nulliparous women were included in the study (82 vacuum-assisted deliveries and 61 forceps-assisted deliveries), with 20 fetuses in occiput posterior position. Forty-seven operative deliveries were classified as complicated deliveries (28 vacuum-assisted deliveries, 19 forceps-assisted deliveries). No differences in obstetric, intrapartum or neonatal characteristics were observed between the study groups, with the following exceptions: birthweight (3229 ± 482 uncomplicated deliveries vs. 3623 ± 406 complicated deliveries; p operating characteristics curve (AUC), were the angle of progression with active pushing (AoP2) (AUC 86.9%) and the progression distance with active pushing (PD2) (AUC 74.5%). The optimal cut-off value for predicting a difficult operative delivery was an AoP2 of 153.5° (sensitivity 95.2%; false-positive rate 5.9%) or PD2 of 58.5 mm (sensitivity 95.2%; false-positive rate 7.1%). The sonographic parameters AoP2 and PD2 can be used to predict cases of complicated operative deliveries in nulliparous women. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

  13. Premenstrual syndrome: a psychological overview. (United States)

    Riven, L


    This paper reviews the premenstrual syndrome (PMS) from a historical and psychological perspective. The physician must recognize that the premenstruum-the four days before the onset of the menses-is a `high risk' phase for women. They may demonstrate somatic and psychological complaints such as irritability, aggression, tension, anxiety, depression, lethargy, insomnia, poor coordination and concentration. Psychological disturbances can range from self-deprecation and the feeling that `everything is too much' to pronounced feelings of oppression and depression. Psychiatric patients may become even more disturbed at this time. Recent reviews on PMS have studied its etiology and its possible connection to hormone imbalance, but to date there is no complete explanation for the syndrome's psychological symptoms. The most promising treatments for the psychological symptoms of PMS are pyridoxine (although there are conflicting reports about it), antidepressants, benzodiazepines if anxiety and tension dominate, and ongoing psychotherapy for severe cases.

    Full Text Available Successful anaesthetic management for caesarean section in a case with previous pituitary tumour resection, with residual tumour, is reported. The pituitary gland undergoes global hyperplasia during pregnancy. Functional pituitary tumours may exhibit symptomatic enlargement during pregnancy. Growth hormone secreting tumour is associated with acromegaly which has associated anaesthetic implications of difficult airway, systemic hypertension, and diabetes and electrolyte imbalance. Intracranial space occupying lesions can increase intra cranial pressure and compromise cerebral perfusion or cause herniation. We report management of this case.

  15. Effectiveness of insecticidal nets on uncomplicated clinical malaria: a case-control study for operational evaluation. (United States)

    Damien, Georgia Barikissou; Djènontin, Armel; Chaffa, Evelyne; Yamadjako, Sandra; Drame, Papa Makhtar; Ndille, Emmanuel Elanga; Henry, Marie-Claire; Corbel, Vincent; Remoué, Franck; Rogier, Christophe


    In a context of large-scale implementation of malaria vector control tools, such as the distribution of long-lasting insecticide nets (LLIN), it is necessary to regularly assess whether strategies are progressing as expected and then evaluate their effectiveness. The present study used the case-control approach to evaluate the effectiveness of LLIN 42 months after national wide distribution. This study design offers an alternative to cohort study and randomized control trial as it permits to avoid many ethical issues inherent to them. From April to August 2011, a case-control study was conducted in two health districts in Benin; Ouidah-Kpomasse-Tori (OKT) in the south and Djougou-Copargo-Ouake (DCO) in the north. Children aged 0-60 months randomly selected from community were included. Cases were children with a high axillary temperature (≥37.5 °C) or a reported history of fever during the last 48 h with a positive rapid diagnostic test (RDT). Controls were children with neither fever nor signs suggesting malaria with a negative RDT. The necessary sample size was at least 396 cases and 1188 controls from each site. The main exposure variable was "sleeping every night under an LLIN for the 2 weeks before the survey" (SL). The protective effectiveness (PE) of LLIN was calculated as PE = 1 - odds ratio. The declared SL range was low, with 17.0 and 27.5 % in cases and controls in the OKT area, and 44.9 and 56.5 % in cases and controls, in the DCO area, respectively. The declared SL conferred 40.5 % (95 % CI 22.2-54.5 %) and 55.5 % (95 % CI 28.2-72.4 %) protection against uncomplicated malaria in the OKT and the DCO areas, respectively. Significant differences in PE were observed according to the mother's education level. In the context of a mass distribution of LLIN, their use still conferred protection in up to 55 % against the occurrence of clinical malaria cases in children. Social factors, the poor use and the poor condition of an LLIN can be in disfavour with

    This paper presents a novel operational oil spill modelling system based on HF radar currents, implemented in a northwest European shelf sea. The system integrates Open Modal Analysis (OMA), Short Term Prediction algorithms (STPS) and an oil spill model to simulate oil spill trajectories. A set of 18 buoys was used to assess the accuracy of the system for trajectory forecast and to evaluate the benefits of HF radar data compared to the use of currents from a hydrodynamic model (HDM). The results showed that simulated trajectories using OMA currents were more accurate than those obtained using a HDM. After 48h the mean error was reduced by 40%. The forecast skill of the STPS method was valid up to 6h ahead. The analysis performed shows the benefits of HF radar data for operational oil spill modelling, which could be easily implemented in other regions with HF radar coverage. Crown Copyright © 2017.

    Full Text Available The increase in the number of areas where humanitarian emergencies are brought about by armed conflicts, and the enduring nature of these situations, call for research aimed at clarifying the international legal framework for food-aid operations, taking into account the developments and practices in the fields of human rights, humanitarian law, environmental law, and cooperation for sustainable development. In this article, therefore, the Author analyses the general problems of food aid in conflict areas, with a focus on a concrete situation, namely the crisis in Eastern Ukraine. The dramatic situation faced by some Ukrainian regions - where, since the spring of 2014, the World Food Programme (WFP, various other international organizations, the EU and some National Development Cooperations have been operating - underlines, in fact, the importance of reaching a clear understanding of all the different regulatory levels in the field of food aid security and safety.

  1. Beyond Positive Psychology? (United States)

    McNulty, James K.; Fincham, Frank D.


    The field of positive psychology rests on the assumption that certain psychological traits and processes are inherently beneficial for well-being. We review evidence that challenges this assumption. First, we review data from 4 independent longitudinal studies of marriage revealing that 4 ostensibly positive processes—forgiveness, optimistic expectations, positive thoughts, and kindness—can either benefit or harm well-being depending on the context in which they operate. Although all 4 processes predicted better relationship well-being among spouses in healthy marriages, they predicted worse relationship well-being in more troubled marriages. Then, we review evidence from other research that reveals that whether ostensibly positive psychological traits and processes benefit or harm well-being depends on the context of various noninterpersonal domains as well. Finally, we conclude by arguing that any movement to promote well-being may be most successful to the extent that it (a) examines the conditions under which the same traits and processes may promote versus threaten well-being, (b) examines both healthy and unhealthy people, (c) examines well-being over substantial periods of time, and (d) avoids labeling psychological traits and processes as positive or negative.

  3. Ross operation in children and young adults: the Alder Hey case series

    Directory of Open Access Journals (Sweden)

    Pozzi Marco


    Full Text Available Abstract Background The ideal prosthesis for aortic valve replacement in children and young adults has not been found yet. In recent years there has been a renewed interest in the replacement of aortic valve with the pulmonary autograft owing to its advantages of lack of anticoagulation, potential for growth and excellent haemodynamic performance. The purpose of this study was to review our institutional experience at Alder Hey hospital with the Ross procedure in children and young adults. Methods From November 1996 to September 2003, 38 patients (mean age, 13.1 ± 5.7 years underwent the Ross procedure for various aortic valve diseases using the root replacement technique. Clinical and echocardiographic follow-up was performed early (within 30 days, 3 to 6 months, and yearly after surgery. Medical records of all patients were reviewed retrospectively. Results There was 1 perioperative death. The patients were followed-up for a median interval of 36 months and up to 7 years. One patient died 3 years after surgery secondary to ventricular arrhythmia with overall mortality of 5.3%. Actuarial survival at 7 years was 94 ± 2.5% and there was 100% freedom from reoperation for autograft valve dysfunction or any other cause. Balloon dilatation was required in 2 patients for pulmonary homograft stenosis. The haemodynamics at the latest follow-up were also similar to those at the time of discharge after surgery. There was no progression in the degree of aortic regurgitation for 11 patients with trivial and 3 with mild regurgitation. Conclusion Our experience demonstrates that Ross operation is an attractive option for aortic valve replacement in children and young adults. Not only can the operation be accomplished with a low operative risk but the valve function stays normal over a long period of time with minimal alteration in lifestyle and no need for repeated operations to replace the valve as a result of somatic growth of the children.

  4. Verification of operational solar flare forecast: Case of Regional Warning Center Japan (United States)

    Kubo, Yûki; Den, Mitsue; Ishii, Mamoru


    In this article, we discuss a verification study of an operational solar flare forecast in the Regional Warning Center (RWC) Japan. The RWC Japan has been issuing four-categorical deterministic solar flare forecasts for a long time. In this forecast verification study, we used solar flare forecast data accumulated over 16 years (from 2000 to 2015). We compiled the forecast data together with solar flare data obtained with the Geostationary Operational Environmental Satellites (GOES). Using the compiled data sets, we estimated some conventional scalar verification measures with 95% confidence intervals. We also estimated a multi-categorical scalar verification measure. These scalar verification measures were compared with those obtained by the persistence method and recurrence method. As solar activity varied during the 16 years, we also applied verification analyses to four subsets of forecast-observation pair data with different solar activity levels. We cannot conclude definitely that there are significant performance differences between the forecasts of RWC Japan and the persistence method, although a slightly significant difference is found for some event definitions. We propose to use a scalar verification measure to assess the judgment skill of the operational solar flare forecast. Finally, we propose a verification strategy for deterministic operational solar flare forecasting. For dichotomous forecast, a set of proposed verification measures is a frequency bias for bias, proportion correct and critical success index for accuracy, probability of detection for discrimination, false alarm ratio for reliability, Peirce skill score for forecast skill, and symmetric extremal dependence index for association. For multi-categorical forecast, we propose a set of verification measures as marginal distributions of forecast and observation for bias, proportion correct for accuracy, correlation coefficient and joint probability distribution for association, the

    Full Text Available I appreciated that the work can be divided into five chapters designed to explain, if possible, the negative effects of fraud and tax evasion, being serious social and economic phenomena that the countries of the world are facing. The indisputable negative effects that the phenomenon of fraud and tax evasion generates are felt directly on the level of tax revenue receipts, causing major distortions in the functioning of the market mechanism. In Romania, the fiscal and budgetary revenues are dependent on the revenues from indirect taxes (VAT, excises, customs duties etc., while, in the European Union, the contributions of the three major categories of taxes (direct and indirect taxes, social contributions to the formation of revenues are closely related. Fiscal policy, using taxes, generates psychological, financial, economic, social effects on the social-economic environment. The public power that realizes the reality of the consequences of the tax action adopts as a solution changes in the structure of the tax system in order to modulate the effects consistent with the expected outcomes. Therefore, the extent of the outcomes pursued influences the technical characteristics of the taxes, and these on the micro and macroeconomic effects. In this regard I will show that reducing tax evasion allows the creation of budgetary resources necessary to the allocation of funds for economic growth. Tax settlement strategies based on state taxation policy, the influence of fiscal discipline to combat the underground economy and tax evasion, the improvement of methods and procedures used by the tax system in the tax settlement, perception and control are issues of utmost importance to ensure the feeding of the state budget systems with minimal resources required. In Romania, one of the basic economic problems is the lack of investment resources allocated, these being the main contributor to economic growth, in which the reduction of fraud and tax evasion is

  8. Optimization of the Waterbus Operation Plan Considering Carbon Emissions: The Case of Zhoushan City

    Directory of Open Access Journals (Sweden)

    Juying Wang


    Full Text Available Recently, as more people are concerned with the issues around environment protection, research about how to reduce carbon emissions has drawn increasing attention. Encouraging public transportation is an effective measure to reduce carbon emissions. However, overland public transportation does less to lower carbon because of the gradually increasing pressure of the urban road traffic. Therefore, the waterbus along the coast becomes a new direction of the urban public transport development. In order to optimize the operation plan of the waterbus, a bi-level model considering carbon emissions is proposed in this paper. In the upper-level model, a multiple objective model is established, which considers both the interests of the passengers and the operator while considering the carbon emissions. The lower-level model is a traffic model split by using a Nested Logit model. A NSGA-II (Non-dominated Sorting Genetic Algorithm-II algorithm is proposed to solve the model. Finally, the city of Zhoushan is chosen as an example to prove the feasibility of the model and the algorithm. The result shows that the proposed model for waterbus operation optimization can efficiently reduce transportation carbon emissions and satisfy passenger demand at the same time.

  9. The Expansion of UN Peacekeeping Operations and the Case of Lebanon

    Directory of Open Access Journals (Sweden)

    Albert Padrós López


    Full Text Available With almost sixty years of experience, the United Nations peacekeeping operations have again been challenged, this time in Lebanon. These missions have evolved following three trends developed after the Cold War: the transformation of “first-generation” ortraditional missions into other broader and more complex ones; the growing impact of the North/South cleavage in them; and progressive regionalisation. However, the reinforced mission in Lebanon (UNIFIL is an operation with a traditional legacy that has particularities.It is more robust; it is led, exceptionally, by European countries; and it faces numerous challenges. This article examines how, although the above-mentioned trends determine the directives of peacekeeping for the near future, the UNIFIL repeats the need to adopt a classical approach in Lebanon adapted to new realities. The author analyses how, despite not covering some elements on the international security agenda since the September 11th attacks, these operations are reconstituted at the beginning of the 21st century as an indispensableelement in international relations increasingly in need of a social approach.

  14. Effect of Endovascular Interventions on General Surgery Trainee Operative Experience; a Comparison of Case Log Reports. (United States)

    Pedersen, Rose C; Li, Yiping; Chang, Jason S; Lew, Wesley K; Patel, Kaushal Kevin


    Vascular surgery fellowship training has evolved with the widespread adoption of endovascular interventions. The purpose of this study is to examine how general surgery trainee exposure to vascular surgery has changed over time. Review of the Accreditation Council for Graduate Medical Education national case log reports for graduating Vascular Surgery Fellows (VF), and general surgery residents (GSR) from 2001 to 2012 was performed. The number of GSR increased from 1021 to 1098, and the number of VF increased from 96 to 121 from 2001 to 2012. The total number of vascular cases done by VF increased by 1161 since 2001 (298-762), whereas the total number of vascular cases done by GSR has decreased by 40% during this time period (186-116). Vascular fellows increase was due primarily to an increase in endovascular experience; a finding not noted in general surgery residents. Vascular fellow case log changes are due primarily to an increase in endovascular experience that has not been mirrored by general surgery trainees. Open surgery experience has decreased overall for general surgery residents in all major categories, a change not seen in vascular surgery fellows. Copyright © 2016 Elsevier Inc.

  15. The Costs of Operative Complications for Ankle Fractures: A Case Control Study

    Directory of Open Access Journals (Sweden)

    Frank R. Avilucea


    Full Text Available As our healthcare system moves towards bundling payments, it is vital to understand the potential financial implications associated with treatment of surgical complications. Considering that surgical treatment of ankle fractures is common, there remains minimal data relating costs to postsurgical intervention. We aimed to identify costs associated with ankle fracture complications through case-control analysis. Using retrospective analysis at a level I trauma center, 28 patients with isolated ankle fractures who developed complications (cases were matched with 28 isolated ankle fracture patients without complications (controls based on ASA score, age, surgery type, and fracture type. Patient charts were reviewed for demographics and complications leading to readmission/reoperation and costs were obtained from the financial department. Wilcoxon tests measured differences in the costs between the cases and controls. 28 out of 439 patients (6.4% developed complications. Length of stay and median costs were significantly higher for cases than controls. Specifically, differences in total costs existed for infection and hardware-related pain. This is the first study to highlight the considerable costs associated with the treatment of complications due to isolated ankle fractures. Physicians must therefore emphasize methods to control surgical and nonsurgical factors that may impact postoperative complications, especially under a global payment system.

  16. Operation care: a pilot case management intervention for frequent emergency medical system users. (United States)

    Rinke, Michael L; Dietrich, Elisabeth; Kodeck, Traci; Westcoat, Kathleen


    This study aims to determine if a prehospital case management intervention reduces transport and nontransport emergency medical system (EMS) responses to frequent EMS users. The 25 most frequent EMS users in a major metropolitan area were identified, and 10 were enrolled in the intervention. These patients received linkage to psychosocial and medical resources through weekly case management visits for 5 to 12 weeks between May and August 2008. Main outcome measures were the number of transport and nontransport EMS responses to patients during the intervention as compared with predicted EMS responses based on each patient's previous year's EMS use. Transport data were available for all patients, but nontransport data were unavailable for 1 patient who was homeless and 6 patients living in apartment buildings. Secondary outcome measures included cost savings to the entire health care system and the Baltimore City Fire Department. Transport responses decreased 32% over the 76 predicted transport responses during the intervention, and nontransport responses decreased 79% over the 24 predicted nontransport responses during the intervention. Including the dedicated case manager's salary, this represented a cost savings to the entire health care system and to the Baltimore City Fire Department of $14 461 and $6311, respectively, over 12 weeks. Prehospital case management may reduce EMS use in high-frequency EMS users and create significant cost savings to municipalities and the health care system. Additional large-scale studies are needed to validate these findings. Copyright © 2012 Elsevier Inc. All rights reserved.

  17. Kinesiophobia in pre-operative patients with cervical discopathy and coexisting degenerative changes in relation to pain-related variables, psychological state and sports activity. (United States)

    Misterska, Ewa; Jankowski, Roman; Głowacki, Jakub; Shadi, Milud; Walczak, Michał; Głowacki, Maciej


    No research group has ever investigated the level of kinesiophobia in a well defined group of preoperative patients treated due to cervical discopathy and degenerative spine disease, confirmed by X-ray and magnetic resonance imaging (MRI) examinations. We aimed to investigate the degree of kinesiophobia and the differences in pain-related and psychosocial characteristics between patients with high and low levels of kinesiophobia, in relation to factors commonly associated with neck pain. Sixty-five consecutive patients with cervical discopathy and coexisting degenerative changes were assessed pre-surgically. The mean pain duration was 31.7 SD 34.0 months. Patients completed the Polish versions of the Tampa Scale for Kinesiophobia (TSK-PL) on 2 occasions, and the following once: Neck Disability Index (NDI-PL), State-Trait Anxiety Inventory (STAI-PL), Coping Strategies Questionnaire (CSQ-PL), and the Visual Analogue Scale (VAS-PL). A high level of kinesiophobia was indicated in 81.5% and 87.7% of patients in first and second completion, respectively. Patients with high and low kinesiophobia differ in regards to the recreation section of NDI-PL (p=0.012), gender (p=0.043), and sports activity (p=0.024). Correlations were identified between TSK-PL and marital status (p=0.023) and sports activity (p=0.024). Kinesiophobia levels are higher in patients with chronic cervical pain before surgical treatment. Fear of movement tends to be higher in women and among patients avoiding sports recreation before surgical treatment. Although sports activity and socio-demographic data are predictors of kinesiophobia, psychological, pain-related, and clinical data are not. These findings should be considered when planning rehabilitation after surgical treatment of cervical discopathy and coexisting degenerative changes.

    Background & Purpose Chronic Exertional Compartment Syndrome (CECS) causes significant exercise related pain secondary to increased intra-compartmental pressure (ICP) in the lower extremities. CECS is most often treated with surgery with minimal information available on non-operative approaches to care. This case report presents a case of CECS successfully managed with physical therapy. Study Design Case report Case Description A 34-year-old competitive triathlete experienced bilateral anterior and posterior lower leg pain measured with a numerical pain rating scale of 7/10 at two miles of running. Pain decreased to resting levels of 4/10 two hours post exercise. The patient was diagnosed with bilateral CECS with left lower extremity ICP at rest measured at 36 mmHg (deep posterior), 36-38 mmHg (superficial posterior), and 25 mmHg (anterior). Surgery was recommended. Interventions The patient chose non-operative care and was treated with physical therapy using the Functional Manual Therapy approach aimed at addressing myofascial restrictions, neuromuscular function and motor control deficits throughout the lower quadrant for 23 visits over 3.5 months. Outcomes At discharge the patient had returned to running pain free and training for an Olympic distance triathlon. The Lower Extremity Functional Scale improved from 62 to 80. The patient reported minimal post exercise tightness in bilateral lower extremities. Left lower extremity compartment pressure measurements at rest were in normal ranges measuring at 11 mmHg (deep posterior), 8 mmHg (superficial posterior), 19 mmHg (anterior), and 10 mmHg (lateral). Three-years post intervention the patient remained pain free with a Global Rating of Change of 6. Discussion This case report describes the successful treatment of a triathlete with Functional Manual Therapy resulting in a return to competitive sports without pain.

    Elena Cantone


    Full Text Available Obstructive sleep apnea syndrome (OSAS is a common disorder in childhood with high prevalence in syndromic subjects with craniofacial malformations. Proteus Syndrome (PS is a rare hamartoneoplastic disorder associated with disproportionate and asymmetric overgrowth of body parts and hypertrophy or malformation of lymphatic tissues, such as palatine tonsils. We report a case of a 12-year-old boy diagnosed with Proteus Syndrome (PS and suffering from OSAS due to asymmetric palatine tonsillar hypertrophy, treated with partial resection of left tonsil. To avoid the risk of a general anesthesia and remove only the obstructive portion of the palatine tonsil bipolar radiofrequency-induced thermotherapy (RFITT under local anesthesia was performed. Recovery of the obstructive respiratory disease was obtained. To our knowledge, this is the first case reported in the literature of partial tonsillar resection performed in a patient with PS suffering from OSAS under local anesthesia.

    Directory of Open Access Journals (Sweden)

    Milan Erdoglija


    Full Text Available Unilateral otosclerosis combined with avascular necrosis of stapes crura is a rare entity. It should be considered in a case of high grade otosclerosis. Symptoms are the same as in patients who suffer from common otosclerosis. Patients complain on progressive hearing loss and tinnitus. The diagnosis is made clinically by conventional audiologic evaluation and radiologically by x-ray mastoid Schuller’s view and CT scan. HRCT scan makes visible all parts of ossicular chain and gives surgeon some information about ossicular chain damage. Surgery with stapedotomy and stapes prosthesis implantation in a case of otosclerosis with avascular necrosis of stapes crura can be success therapy to improve patient’s hearing.

    ENGLISH ABSTRACT: This study was done to assist a local auto carrier company with tactical operational planning. The objective of the planning process is to maximise the number of vehicles delivered while being on time and adhering to staff and maintenance schedule constraints.

    We investigated the feasibility of allowing part of the fleet to roam the closed spatial network, as opposed to the traditional assignment of the complete fleet to fixed routes. We developed decision-making rules for roaming and fixed-to-route auto carriers, and evaluated the quality of these proposed rules, in combination with different fleet compositions, using discrete event simulation and four performance measures.

    We found that the auto carrier company should adopt a tactical operations policy where at least 50% of the fleet is allowed to roam, while roaming auto carriers pick vehicles to transport according to specific rules.

    Walsh, Thomas L; Querry, Ashley M; McCool, Sheila; Galdys, Alison L; Shutt, Kathleen A; Saul, Melissa I; Muto, Carlene A


    OBJECTIVE To determine risk factors for the development of surgical site infections (SSIs) in neurosurgery patients undergoing spinal fusion. DESIGN Retrospective case-control study. SETTING Large, academic, quaternary care center. PATIENTS The study population included all neurosurgery patients who underwent spinal fusion between August 1, 2009, and August 31, 2013. Cases were defined as patients in the study cohort who developed an SSI. Controls were patients in the study cohort who did not develop an SSI. METHODS To achieve 80% power with an ability to detect an odds ratio (OR) of 2, we performed an unmatched case-control study with equal numbers of cases and controls. RESULTS During the study period, 5,473 spinal fusion procedures were performed by neurosurgeons in our hospital. With 161 SSIs recorded during the study period, the incidence of SSIs associated with these procedures was 2.94%. While anterior surgical approach was found to be a protective factor (OR, 0.20; 95% confidence interval [CI], 0.08-0.52), duration of procedure (OR, 1.58; 95% CI, 1.29-1.93), American Society of Anesthesiologists score of 3 or 4 (OR, 1.79; 95% CI, 1.00-3.18), and hospitalization within the prior 30 days (OR, 5.8; 95% CI, 1.37-24.57) were found in multivariate analysis to be independent predictors of SSI following spinal fusion. Prior methicillin-resistant Staphylococcus aureus (MRSA) nares colonization was highly associated with odds 20 times higher of SSI following spinal fusion (OR, 20.30; 95% CI, 4.64-8.78). CONCLUSIONS In additional to nonmodifiable risk factors, prior colonization with MRSA is a modifiable risk factor very strongly associated with development of SSI following spinal fusion.

    Little is known about pitching performance or lack of it among Major League Baseball (MLB) pitchers who undergo operative treatment of rotator cuff tears. To assess pitching performance outcomes in MLB players who needed operative treatment of rotator cuff tears and to compare performance in these athletes with that in a control group of MLB players. Case-control study. Publicly available player profiles, press releases, and team injury reports. Thirty-three MLB pitchers with documented surgery to treat rotator cuff tears and 117 control pitchers who did not have documented rotator cuff tears were identified. Major League Baseball pitching attrition and performance variables. Players who underwent rotator cuff surgery were no more likely not to play than control players. Performance variables of players who underwent surgery improved after surgery but never returned to baseline preoperative status. Players who needed rotator cuff surgery typically were more experienced and had better earned run averages than control players. Pitchers who had symptomatic rotator cuff tears that necessitated operative treatment tended to decline gradually in performance leading up to their operations and to improve gradually over the next 3 seasons. In contrast to what we expected, they did not have a greater attrition rate than their control counterparts; however, their performances did not return to preoperative levels over the course of the study.

    Hardy, Krista L; Davis, Kathryn E; Constantine, Ryan S; Chen, Mo; Hein, Rachel; Jewell, James L; Dirisala, Karunakar; Lysikowski, Jerzy; Reed, Gary; Kenkel, Jeffrey M


    Little evidence within plastic surgery literature supports the precept that longer operative times lead to greater morbidity. The authors investigate surgery duration as a determinant of morbidity, with the goal of defining a clinically relevant time for increased risk. A retrospective chart review was conducted of patients who underwent a broad range of complex plastic surgical procedures (n = 1801 procedures) at UT Southwestern Medical Center in Dallas, Texas, from January 1, 2008 to January 31, 2012. Adjusting for possible confounders, multivariate logistic regression assessed surgery duration as an independent predictor of morbidity. To define a cutoff for increased risk, incidence of complications was compared among quintiles of surgery duration. Stratification by type of surgery controlled for procedural complexity. A total of 1753 cases were included in multivariate analyses with an overall complication rate of 27.8%. Most operations were combined (75.8%), averaging 4.9 concurrent procedures. Each hour increase in surgery duration was associated with a 21% rise in odds of morbidity (P surgery (odds ratio, 1.6; P = .017), with progressively greater odds increases of 3.1 times after 4.5 hours (P surgery, longer operations continued to be associated with greater morbidity. Surgery duration is an independent predictor of complications, with a significantly increased risk above 3 hours. Although procedural complexity undoubtedly affects morbidity, operative time should factor into surgical decision making.

  7. Post-operative nausea and vomiting following paediatric day-case tonsillectomy: audit of the Epsom protocol. (United States)

    Robb, P J; Ewah, B N


    To audit a protocol for elective, day-case, paediatric ENT surgery, previously reported as enabling an overall post-operative nausea and vomiting rate of 2 per cent and a discharge rate of 100 per cent on the day of surgery. The audit included 91 children (45 boys and 46 girls) aged three to 14 years. Forty-seven children underwent tonsillectomy, 36 adenotonsillectomy and eight tonsillectomy with postnasal space examination; indications included recurrent tonsillitis, tonsillitis and nasal block, upper airway obstruction, and a combination of upper airway obstruction and recurrent tonsillitis. No post-operative nausea or vomiting was recorded in any of the children on the day of surgery, and no discharges were delayed. The reactionary haemorrhage rate was 1 per cent and the secondary haemorrhage rate 3.3 per cent. These findings have implications for the safe same-day discharge of children following tonsillectomy.

  8. Operative management of cryptorchidism: guidelines and reality--a 10-year observational analysis of 3587 cases. (United States)

    Hensel, Kai O; Caspers, Tawa; Jenke, Andreas C; Schuler, Ekkehard; Wirth, Stefan


    Undescended testis (UDT) is the most common disorder in pediatric surgery and one of the most important risk factors for malignancy and subfertility. In 2009 local guidelines were modified and now recommend treatment to be completed by the age of 1. Aim of this study was to analyze age distribution at the time of orchidopexy, whether the procedure is performed according to guideline recommendations and to assess primary care pediatricians' attitude regarding their treatment approach. We retrospectively analyzed 3587 patients with UDT regarding age at orchidopexy between 2003 and 2012 in 13 German hospitals. Furthermore, we conducted an anonymized nation-wide survey among primary care pediatricians regarding their attitude toward management of UDT. Before modification of the guideline 78% (n = 1245) of the boys with UDT were not operated according to guideline recommendations. After the modification that number rose to 95% (n = 1472). 42% of the orchidopexies were performed on patients aged 4 to 17 years. 46% of the primary care pediatricians were not aware of this discrepancy and 38% would only initiate operative management after the first year of life. In hospitals with pediatric surgery departments significantly more patients received orchidopexy in their first year of life (p order to improve long-term prognosis. Both primary care providers and parents should be educated regarding the advantages of early orchidopexy in UDT. Prospective studies are needed to elucidate the high rate of late orchidopexies.

  9. Inspection of a hydropower tunnel using remotely operated vehicles (ROV): A 5-year case study

    Energy Technology Data Exchange (ETDEWEB)

    Hosko, M.A. [Pennsylvania Rural Electric Association and Allegheny Electric Cooperative, Inc., Harrisburg, PA (United States)


    Since commercial operation in 1988, the 21 MW Raystown Hydroelectric Project, William F. Matson Generating Station in central Pennsylvania, has used several different methods to inspect the condition of the 283-meter (930-foot) long, 3.65-meter (12-foot) diameter, concrete-lined tunnel. These inspections have been required to meet the FERC license conditions and the separate Memorandum of Understanding (MOU) between the U.S. Army Corps of Engineers, Baltimore District and the Licensee, Allegheny Electric Cooperative, Inc., of Harrisburg, PA. Since the tunnel and connected 168-meter (550-foot) long steel penstock are the only water passage to the two-unit generating plant, any intrusive inspection requires an outage, thus the optimal inspection technique minimizes the plant downtime. Inspections have included a lengthy and costly dewatered tunnel walk through, an underwater inspection using commercial divers and hand-held video, and most recently three annual inspections using three different types of Remotely Operated Vehicles (ROV) supplied by vendor services. Each inspection concentrated on the examination of the condition of the tunnel concrete, including radial cracks and condition of construction joints, longitudinal crack propagation, aggregate erosion and concrete patch condition. Use of a computerized database program for mapping will also be discussed as a useful tool. This paper details experience with each of these methods with an emphasis on lessons learned and applications for the hydro industry.

  10. Effect of distractions on operative performance and ability to multitask--a case for deliberate practice. (United States)

    Ahmed, Aadil; Ahmad, Mueen; Stewart, C Matthew; Francis, Howard W; Bhatti, Nasir I


    To measure the effect of distractions on the operative performance and analyze if practice and experience are the factors that can help to overcome the distractions. Prospective observational study. Ten postgraduate year (PGY) 2-6 residents and two faculty members from Johns Hopkins' otolaryngology department were recruited and asked to deepen the dissection at the sinodural angle on the Voxel-man mastoidectomy simulator. They were asked to perform the task under four conditions: 1) no distractors, 2) differentiation and counting of a specific alarm sound among different sounds played in the background while performing the surgical task, 3) simultaneous performance of simple arithmetic task of moderate difficulty, and 4) simultaneous performance of the task with both sets of distractors combined. Time taken for the task (P = .02) and error scores (P = .002) increased under the third and fourth conditions. The ability to multitask and response to surgical and cognitive tasks improved with increasing level of experience of the participants. Distractions lead to impaired dexterity and an increase in the incidence of errors. However, experience and deliberate practice can help achieve the ability to multitask without compromising the operative performance. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

  11. Reducing aluminum dust explosion hazards: case study of dust inerting in an aluminum buffing operation. (United States)

    Myers, Timothy J


    Metal powders or dusts can represent significant dust explosion hazards in industry, due to their relatively low ignition energy and high explosivity. The hazard is well known in industries that produce or use aluminum powders, but is sometimes not recognized by facilities that produce aluminum dust as a byproduct of bulk aluminum processing. As demonstrated by the 2003 dust explosion at aluminum wheel manufacturer Hayes Lemmerz, facilities that process bulk metals are at risk due to dust generated during machining and finishing operations [U.S. Chemical Safety and Hazard Investigation Board, Investigation Report, Aluminum Dust Explosion Hayes Lemmerz International, Inc., Huntington, Indiana, Report No. 2004-01-I-IN, September 2005]. Previous studies have shown that aluminum dust explosions are more difficult to suppress with flame retardants or inerting agents than dust explosions fueled by other materials such as coal [A.G. Dastidar, P.R. Amyotte, J. Going, K. Chatrathi, Flammability limits of dust-minimum inerting concentrations, Proc. Saf. Progr., 18-1 (1999) 56-63]. In this paper, an inerting method is discussed to reduce the dust explosion hazard of residue created in an aluminum buffing operation as the residue is generated. This technique reduces the dust explosion hazard throughout the buffing process and within the dust collector systems making the process inherently safer. Dust explosion testing results are presented for process dusts produced during trials with varying amounts of flame retardant additives.

  12. Stressful work characteristics, health indicators and work behavior: the case of machine operators. (United States)

    Mościcka-Teske, Agnieszka; Sadłowska-Wrzesińska, Joanna; Butlewski, Marcin; Misztal, Agnieszka; Jacukowicz, Aleksandra


    This article shows the results of research on psychosocial risks for a group of machine and plant operators (n = 1014) from the construction, chemical, energy, mining, metal and food industries in Poland. The Psychosocial Risk Scale designed in Nofer Institute of Occupational Medicine (NIOM) by Moscicka-Teske and Potocka was used to indicate the occurrence of general and specific occupational stressors and the level of their stressfulness. The results revealed that the studied machine and plant operators experience job context stress - related to working environment features concerning work organization - more frequently than job content stressors - related to the type of tasks they perform. Moreover, a correlation analysis between work features and the health and occupational functioning of the respondents revealed significant but weak relationships between the variables (from -0.08 to -0.23). Comparative analysis revealed the differences between the studied sectors. Such a comparison makes it possible to set goals for each sector and to attempt to improve the distinctive areas.

    Highlights: • We validate operator actions in case of primary to secondary leakage. • We perform four scenarios related to SGTR accident for VVER-1000/V320. • The reference power plant for the analyses is Unit 6 at Kozloduy NPP. • The RELAP5/MOD 3.2 computer code is used in performing the analyses. • The analyses confirm the effectiveness of operator actions during PRISE. - Abstract: This paper presents the results of analytical validation of operator actions in case of “Steam Generator Tube Rupture” (SGTR) for VVER-1000/V320 units at Kozloduy Nuclear Power Plant (KNPP), done during the development of Symptom Based Emergency Operating Procedures (SB EOPs) for this plant. The purpose of the analyses is to demonstrate the ability to terminate primary to secondary leakage and to indicate an effective strategy for preventing secondary leakage to the environment and in this way to prevent radiological release to the environment. Following depressurization and cooldown of reactor coolant system (RCS) with isolation of the affected steam generator (SG), in these analyses are validated options for post-SGTR cooldown by: • back up filling the ruptured SG; • using letdown system in the affected SG and • by opening Fast Acting Isolation Valve (FAIV) and using Steam Dump Facility to the Condenser (BRU-K). The results of the thermal-hydraulic analyses have been used to assist KNPP specialists in analytical validation of EOPs. The RELAP5/MOD3.2 computer code has been used for the analyses in a VVER-1000 Nuclear Power Plant (NPP) model. A model of VVER-1000 based on Unit 6 of Kozloduy NPP has been developed for the thermal-hydraulics code RELAP5/MOD3.2 at the Institute for Nuclear Research and Nuclear Energy – Bulgarian Academy of Sciences (INRNE-BAS). This paper is possible through the participation of leading specialists from KNPP.

  14. An evaluation of the psychological impact of operational rest and recuperation in United Kingdom Armed Forces personnel: a post-intervention survey. (United States)

    Jones, Norman; Fertout, Mohammed; Parsloe, Laura; Greenberg, Neil


    Rest and Recuperation (R&R) is a period of home leave taken during an operational deployment; we sought to examine the relationship between taking R&R and mental health. A survey-based post-intervention evaluation. UK PARTICIPANTS: 232 members of the UK Armed Forces; 42 of which completed pre and post R&R surveys. Alcohol use, Post Traumatic Stress Disorder, Common Mental Disorder Symptoms and R&R experiences. 12.1% of respondents (n=27) reported symptoms of common mental disorder and 3.7% (n=8) reported probable PTSD. 50.0% (n=110) reported hazardous use of alcohol during R&R. In the pre- and post-assessed sample, mental health status and alcohol use levels were similar at both survey points. Using principal component analysis, five components of R&R were identified; mentally switching off from deployment, travel experience, physical recovery, relaxation, rest and social support. R&R was extremely popular and although it did not improve mental health overall, the ability to engage with or derive satisfaction from aspects of the five components was significantly associated with better mental health and less alcohol use at the end of R&R. Operational commanders should advise personnel about the best way to actively engage with R&R before they leave theatre and be aware of the significant detrimental impact of disrupted travel arrangements upon the ability to benefit from R&R.

  18. Pathology and surgery of bell's palsy: A report of 108 cases subjected to the ballance-duel operation

    Directory of Open Access Journals (Sweden)

    Karsten Kettel


    Full Text Available The majority of cases of Bell's palsy are due to ischaemia of the facial nerve near the stylomastoid foramen. Following lack of blood supply the nerve loses its power of conduction, and venous stasis arises with ensuing swelling of the nerve, which becomes secondarily compressed within the Fallopian canal. The therapy of choice is medical treatment aiming to relieve the vasoconstriction and maintain the contractility of the muscles. Surgical decompression of the facial nerve is indicated in a limited number of cases, and the results of 108 operations are briefly recorded. Decompression should be performed in both fresh and relapsing palsies if no signs of spontaneous movement are observed after two months of observation. With patients in whom spontaneous recovery has ceased be-fored complete restitution has been obtained, further improvement may be expected from decompression.

  1. Continuous peripheral nerve block catheter infections in combat-related injuries: a case report of five soldiers from Operation Enduring Freedom/Operation Iraqi Freedom. (United States)

    Lai, Tristan T; Jaeger, Lisa; Jones, Benjamin L; Kaderbek, Eric W; Malchow, Randall J


    Case series. Military medical facility providing acute care for soldiers injured while fighting in the war in Iraq and Afghanistan. To report a series of infections related to use of continuous peripheral nerve catheters for postoperative pain control in the military polytraumatic setting. The analysis of the above infections includes similarities and differences in infection patterns and attempts to clarify possible risk factors for such infections to include duration of catheter placement, type of catheter, preprocedural antibiotics, and tunnel vs nontunneled catheters. The goal of this analysis is to assist in the development of protocols that may prevent future catheter infections. Clinical data were obtained from five previously healthy male soldiers receiving acute care at Brooke Army Medical Center using continuous peripheral nerve catheters for postoperative pain for multiple and frequent procedures. In a total of six catheter infections, two were noted to have superficial skin infections while four were shown to have deep tissue involvement confirmed by imaging studies. All patients were started on initial or additional antibiotics after catheter removal. Three catheter infections, all with stimulating catheters, required surgical irrigation and debridement in the operating room. Continuous peripheral nerve catheters are not without complications and risks including infection. Duration of catheter use was the most significant factor with the development of a catheter-related infection in our series. This series also highlights how stimulating and nonstimulating catheter infections may present differently, as stimulating catheters may have a greater tendency to present as deep space infections with minimal superficial findings.

  2. Qualitative methods in operations research on contraceptive distribution systems: a case study from Nigeria. (United States)

    Webb, G; Ladipo, O A; McNamara, R


    This article discusses the application of qualitative methods in operations research on a family planning service delivery system. Market traders in Ibadan, Nigeria were trained to sell oral contraceptives, condoms, and spermicidal foaming tablets in a collaborative research project of the Fertility Research Unit of the University College Hospital, Ibadan, and the Center for Population and Family Health of Columbia University. Focus group discussion, participant observation, and semi-structured interviews were used to investigate the cultural acceptability of distribution of contraceptives in the market places and the motivations of participating traders. The strength of the market associations was a factor influencing acceptance of the project and the number of customers for the traders' other wares were found to positively influence the volume of sales of contraceptives. Traders were motivated by the status associated with participating in a program of a well-known health institution. Findings from qualitative research suggest areas for quantitative studies and vice versa in an interactive process.

    Vallee, Francois; Lobry, Jacques; Deblecker, Olivier [Mons Univ. (Belgium). Dept. of Electrical Engineering


    In this paper, a strategy is proposed in order to introduce in a realistic way wind generation into a HLII (bulk power system) non sequential Monte Carlo adequacy study with economic dispatch. Thanks to the implemented solution, wind generation is consequently confronted to operational constraints related to high powered thermal units, nuclear parks or thermal machines with technical minimum value. Moreover, during each simulated system state, a DC load flow is also calculated in order to evaluate reinforcements optimizing the large scale integration of wind power production. The simulation tool modified during the present work is called Scanner {sup copyright} and is the property of Tractebel Engineering (Gaz de France - Suez) company. It has been firstly applied to an academic test system: the Roy Billinton Test System (RBTS). Finally, in order to fully access the large offshore wind potential in the North Sea, the proposed simulation tool has been used to evaluate the onshore reinforcements required in the Belgian transmission network.

  4. Case study of restaurant successfully designed, constructed, and operated for excellent dining acoustics (United States)

    Bollard, Paul; Des Jardins, Stephen


    Prior to the construction of La Provence Restaurant in Roseville, California in 2004, the owner, Stephen Des Jardins, traveled with his cook, architect, and engineer to the Provence Region of France to study the cuisine, architecture, and acoustics of the local restaurants. This information was incorporated into the design, construction, and operation of his restaurant, with acoustical design assistance provided by the author, Paul Bollard. The result of the owner's painstaking attention to detail is a restaurant which has received very positive reviews for its architecture, quality of food, service, and acoustic ambience. This paper documents the measures included in the construction of the restaurant to ensure that the building acoustics enhance the dining experience, rather than detract from it. Photographs of acoustic treatments are included, as are reverberation time (RT60) test results and ambient noise level measurement results.

    Lemerle, Sophie


    Adolescence is a transitional period dominated by puberty modifications. These modifications must come with a psychological work leading towards increased self containing from parents and also towards the choice of an own life orientation. In order to do so, adolescent must satisfy his needs to be able to change. This process will not run smoothly. The troubled adolescent will express himself with groans or acting out more than with words. This modus operandi is typical of that age. The general practitioner will be in the front line in being attentive to the adolescent and his parents needs.

  6. Benthic foraminiferal responses to operational drill cutting discharge in the SW Barents Sea - a case study. (United States)

    Aagaard-Sørensen, Steffen; Junttila, Juho; Dijkstra, Noortje


    Petroleum related exploration activities started in the Barents Sea 1980, reaching 97 exploration wells drilled per January 2013. The biggest operational discharge from drilling operations in the Barents Sea is the release of drill cuttings (crushed seabed and/or bedrock) and water based drilling muds including the commonly used weighing material barite (BaSO4). Barium (Ba), a constituent of barite, does not degrade and can be used to evaluate dispersion and accumulation of drill waste. The environmental impact associated with exploration drilling within the Goliat Field, SW Barents Sea in 2006 was evaluated via a multiproxy investigation of local sediments. The sediments were retrieved in November 2014 at ~350 meters water depth and coring sites were selected at distances of 5, 30, 60, 125 and 250 meters from the drill hole in the eastward downstream direction. The dispersion pattern of drill waste was estimated via measurements of sediment parameters including grain size distribution and water content in addition to heavy metal and total organic carbon contents. The environmental impact was evaluated via micro faunal analysis based on benthic foraminiferal (marine shell bearing protists) fauna composition and concentration changes. Observing the sediment parameters, most notably Ba levels, reveals that dispersion of drill waste was limited to waste thicknesses decreasing downstream. The abruptness and quantity of drill waste sedimentation initially smothered the foraminiferal fauna at ≤ 30 meters from the drill site, while at a distance of 60 meters, the fauna seemingly survived and bioturbation persisted. Analysis of the live (Nov 2014) foraminiferal fauna reveals a natural species composition at all distances from the drill site within the top sediments (0-5 cm core depth). Furthermore, the fossil foraminiferal fauna composition found within post-impacted top sediment sections, particularly in the cores situated at 30 and 60 meters from the drill site

    Full Text Available BACKGROUND The relationship of the various positions of appendix to its clinical picture and course in the patient is a subject of controversy. The objective is to study the correlation between anatomical position of appendix and its varied clinical presentation and also to determine the frequency of different positions of appendix in operated cases of acute appendicitis. MATERIALS AND METHODS This study was conducted from Nov 2012 to April 2014 for a period of 16 months in MVJ Medical College and Research Hospital, Hoskote, Bangalore. There were 150 cases in the study, which were histopathologically positive for appendicitis. RESULTS There were total of 150 cases. The commonest position of the appendix is retrocaecal (67.3% followed by pelvic (16%, preileal (7.3%, post-ileal (4.6%, paracaecal (2.6%, subcaecal (1.3% and subhepatic (0.6%. Certain positions like fixed retrocaecal, pelvic and post-ileal presented more often atypically. CONCLUSION There is no increased predisposition for any of the position of the appendix to get inflamed. Complications were more common in cases fixed retrocaecal, post-ileal and pelvic appendix. The patients with the above positions presented more often atypically than typically and with subtle signs and symptoms leading to delayed diagnosis and increased complications.

  8. Psychological literacy: proceed with caution, construction ahead

    Murdoch DD


    Full Text Available Douglas D Murdoch Department of Psychology, Mount Royal University, Calgary, AB, Canada Abstract: Psychological literacy is the ethical application of psychological skills and knowledge. This could benefit individuals in their personal, occupational, and civic lives and subsequently benefit society as a whole. We know that psychology has a wide-ranging impact on society. The potential benefits of a psychologically literate citizenry in improved parenting, better business practices, enlightened legislation, and many other areas make this a desirable goal. It has been proposed that this should become the primary goal of an undergraduate psychology education to benefit the majority who do not go on to graduate school and even those who only take a few psychology courses. This idea has significant merit and warrants further investigation and development. However, there are major concerns that need to be addressed. First, what are uniquely psychological skills and knowledge? Many of the skills psychology undergraduates acquire are generic to university and not specific to psychology. Second, psychology can be as harmful when misapplied as it can be beneficial when ethically applied. Third, psychology departments will need to address pragmatic as well as ethical issues, including issues of competency, boundaries, accountability, and confidentiality. Fourth, the available empirical evidence to direct such efforts is primarily at the anecdotal, case example, and pilot study stages. Significant improvements are needed in measuring psychological literacy, choice of outcome measures, and research methodologies before these advantages can be realized in an empirically supported manner. Currently, best practices in the undergraduate curriculum are the mindful and purposeful design of courses and experiential opportunities. It is proposed that psychological literacy is best conceptualized as a meta-literacy and that it should become a goal of psychology

    Full Text Available Abstract Background Carpal tunnel syndrome (CTS is a socially and economically relevant disease caused by compression or entrapment of the median nerve within the carpal tunnel. This population-based case-control study aims to investigate occupational/non-occupational risk factors for surgically treated CTS. Methods Cases (n = 220 aged 18-65 years were randomly drawn from 13 administrative databases of citizens who were surgically treated with carpal tunnel release during 2001. Controls (n = 356 were randomly sampled from National Health Service registry records and were frequency matched by age-gender-specific CTS hospitalization rates. Results At multivariate analysis, risk factors were blue-collar/housewife status, BMI ≥ 30 kg/m2, sibling history of CTS and coexistence of trigger finger. Being relatively tall (cut-offs based on tertiles: women ≥165 cm; men ≥175 cm was associated with lower risk. Blue-collar work was a moderate/strong risk factor in both sexes. Raised risks were apparent for combinations of biomechanical risk factors that included frequent repetitivity and sustained force. Conclusion This study strongly underlines the relevance of biomechanical exposures in both non-industrial and industrial work as risk factors for surgically treated CTS.

  12. Physiological stresses in warehouse operations with special reference to lifting technique and gender: a case study. (United States)

    Garg, A; Saxena, U


    A field study was conducted to evaluate the effects of lifting technique (free-style vs. straight-back, bent-knee) on male workers' performances and physiological responses. A secondary objective was to study physiological stresses to female order selectors using the free-style lifting technique only. Six male and six female workers performed their routine work of grocery order selection in three different warehouses while their oxygen uptake and heart rates were measured. Workers' performances were determined using the traditional work measurement techniques (time study, methods time measurement and master standard data systems) employed by the warehouses. Total cases, weight, volume, actual and allowed time for each order were also determined. Statistical analysis showed that the performance levels of the male workers (allowed time per order * 100/actual time per order) were significantly lower and oxygen uptake and heart rates were higher for the straight-back, bent-knee method as compared to the free-style lifting technique. Male workers lifted more cases, weight and volume/min with the free-style lifting technique than with the straight-back, bent-knee method. It is concluded that the traditionally recommended straight-back, bent knee method of lifting is slower and physiologically more demanding. It is practically impossible for a substantial number of workers to meet the existing time or performance standards based on traditional work measurement techniques--when using the straight-back, bent-knee method of lifting recommended by the warehouses.(ABSTRACT TRUNCATED AT 250 WORDS)

  13. Operational reservoir inflow forecasting with radar altimetry: the Zambezi case study (United States)

    Michailovsky, C. I.; Bauer-Gottwein, P.


    River basin management can greatly benefit from short-term river discharge predictions. In order to improve model produced discharge forecasts, data assimilation allows for the integration of current observations of the hydrological system to produce improved forecasts and reduce prediction uncertainty. Data assimilation is widely used in operational applications to update hydrological models with in situ discharge or level measurements. In areas where timely access to in situ data is not possible, remote sensing data products can be used in assimilation schemes. While river discharge itself cannot be measured from space, radar altimetry can track surface water level variations at crossing locations between the satellite ground track and the river system called virtual stations (VS). Use of radar altimetry versus traditional monitoring in operational settings is complicated by the low temporal resolution of the data (between 10 and 35 days revisit time at a VS depending on the satellite) as well as the fact that the location of the measurements is not necessarily at the point of interest. However, combining radar altimetry from multiple VS with hydrological models can help overcome these limitations. In this study, a rainfall runoff model of the Zambezi River basin is built using remote sensing data sets and used to drive a routing scheme coupled to a simple floodplain model. The extended Kalman filter is used to update the states in the routing model with data from 9 Envisat VS. Model fit was improved through assimilation with the Nash-Sutcliffe model efficiencies increasing from 0.19 to 0.62 and from 0.82 to 0.88 at the outlets of two distinct watersheds, the initial NSE (Nash-Sutcliffe efficiency) being low at one outlet due to large errors in the precipitation data set. However, model reliability was poor in one watershed with only 58 and 44% of observations falling in the 90% confidence bounds, for the open loop and assimilation runs respectively, pointing to

  15. Dam operation for environmental water releases; the case of Osborne dam, Save catchment, Zimbabwe (United States)

    Symphorian, Griphin R.; Madamombe, E.; van der Zaag, Pieter

    There is limited capacity in terms of knowledge and experience on how to calculate the environmental water requirements (EWR) in Zimbabwe. In this paper the EWR were assessed using the desktop model developed by [A Desktop Model used to provide an initial estimate of the ecological instream flow requirements of rivers in South Africa. Institute for Water Research, Rhodes University, Grahamstown, 2001] and a spreadsheet model (Waflex) was developed to incorporate a component of EWR in reservoir simulation. The paper assesses whether EWR as established by Hughes method can be incorporated into a reservoir simulation and water allocation model, and if it is possible to derive EWR directly from naturalised flow series. The paper further considers the possibility of using the concept of capacity sharing for allocating water rights to the environment. The results show that at present use levels the EWR in the Odzi river can easily be met. However when in future water abstractions will increase, the effective water releases for the environmental will increase significantly. Also a very simple method is proposed to establish a first approximation of EWR. The paper shows that the capacity sharing model concept is a transparent institutional arrangement, which can be used to allocate water rights to the environment. It can be concluded that the Waflex model can provide practical guidelines to catchment managers and dam operators to implement EWR.

  16. An Object Model for Integrating Diverse Remote Sensing Satellite Sensors: A Case Study of Union Operation

    Full Text Available In the Earth Observation sensor web environment, the rapid, accurate, and unified discovery of diverse remote sensing satellite sensors, and their association to yield an integrated solution for a comprehensive response to specific emergency tasks pose considerable challenges. In this study, we propose a remote sensing satellite sensor object model, based on the object-oriented paradigm and the Open Geospatial Consortium Sensor Model Language. The proposed model comprises a set of sensor resource objects. Each object consists of identification, state of resource attribute, and resource method. We implement the proposed attribute state description by applying it to different remote sensors. A real application, involving the observation of floods at the Yangtze River in China, is undertaken. Results indicate that the sensor inquirer can accurately discover qualified satellite sensors in an accurate and unified manner. By implementing the proposed union operation among the retrieved sensors, the inquirer can further determine how the selected sensors can collaboratively complete a specific observation requirement. Therefore, the proposed model provides a reliable foundation for sharing and integrating multiple remote sensing satellite sensors and their observations.

  17. Estimation of Bank Erosion Due To Reservoir Operation in Cascade (Case Study: Citarum Cascade Reservoir

    Directory of Open Access Journals (Sweden)

    Sri Legowo


    Full Text Available Sedimentation is such a crucial issue to be noted once the accumulated sediment begins to fill the reservoir dead storage, this will then influence the long-term reservoir operation. The sediment accumulated requires a serious attention for it may influence the storage capacity and other reservoir management of activities. The continuous inflow of sediment to the reservoir will decrease the capacity of reservoir storage, the reservoir value in use, and the useful age of reservoir. Because of that, the rate of the sediment needs to be delayed as possible. In this research, the delay of the sediment rate is considered based on the rate of flow of landslide of the reservoir slope. The rate of flow of the sliding slope can be minimized by way of each reservoir autonomous efforts. This effort can be performed through; the regulation of fluctuating rate of reservoir surface current that does not cause suddenly drawdown and upraising as well. The research model is compiled using the searching technique of Non Linear Programming (NLP.The rate of bank erosion for the reservoir variates from 0.0009 to 0.0048 MCM/year, which is no sigrificant value to threaten the life time of reservoir.Mean while the rate of watershed sediment has a significant value, i.e: 3,02 MCM/year for Saguling that causes to fullfill the storage capacity in 40 next years (from years 2008.

    Batch anaerobic digestion was employed to investigate the efficient start-up strategies for the liquefied food waste, and sequencing batch digestion was also performed to determine maximum influent organic loading rate (OLR) for efficient and stable operation. The results indicated that the start-up could be well improved using appropriate wastewater organic load and food-to-microorganism ratios (F/M). When digestion was initialized at low chemical oxygen demand (COD) concentration of 20.0 gCOD L(-1), the start-up would go well using lower F/M ratio of 0.5-0.7. The OLR 7.0 gCOD L(-1) day(-1) was recommended for operating the ASBR digestion, in which the COD conversion of 96.7 ± 0.53% and biomethane yield of 3.5 ± 0.2 L gCOD(-1) were achieved, respectively. The instability would occur when OLR was higher than 7.0 gCOD L(-1) day(-1), and this instability was not recoverable. Lipid was suggested to be removed before anaerobic digestion. The anaerobic digestion process in engineering project ran well, and good performance was achieved when the start-up and operational strategies from laboratory study were applied. For case application, stable digestion performance was achieved in a digester (850 m(3) volume) with biogas production of 1.0-3.8 m(3) m(-3) day(-1).

  20. Integrating Strategic and Operational Decision Making Using Data-Driven Dashboards: The Case of St. Joseph Mercy Oakland Hospital. (United States)

    Jack Weiner; Balijepally, Venugopal; Tanniru, Mohan


    Hospitals have invested and continue to invest heavily in building information systems to support operations at various levels of administration. These systems generate a lot of data but fail to effectively convert these data into actionable information for decision makers. Such ineffectiveness often is attributed to a lack of alignment between strategic planning and information technology (IT) initiatives supporting operational goals. We present a case study that illustrates how the use of digital dashboards at St. Joseph Mercy Oakland (SJMO) Hospital in Pontiac, Michigan, was instrumental in supporting such an alignment. Driven by a focus on key performance indicators (KPIs), dashboard applications also led to other tangible and intangible benefits. An ability to track KPIs over time and against established targets, with drill-down capabilities, allowed leadership to hold staff members accountable for achieving their performance targets. By displaying the dashboards in prominent locations (such as operational unit floors, the physicians' cafeteria, and nursing stations), SJMO ushered in transparency in the planning and monitoring processes. The need to develop KPI metrics and drive data collection efforts became ingrained in the work ethos of people at every level of the organization. Although IT-enabled dashboards have been instrumental in supporting this cultural transformation, the focus of investment was the ability of technology to make collective vision and action the responsibility of all stakeholders.
