    United States Military Psychological Operations are engaged in a type of mass marketing of ideas. To accomplish this The United States Army Civil Affairs and Psychological Operations Command (USACAPOC) employs active and reserve PSYOP units to conduct PSYOP campaigns. However the methodology used to manage these campaigns often hinders the effective employment of timely and effective Psychological Operations. PSYOP has a difficult job to accomplish but PSYOP does not have the proper managemen...

    Traditional accounts of the Individual Psychology of Alfred Adler tend to sentimentalize his system and obscure its functional flavor. Six basic Adlerian positions on human behavior, including Rudolf Dreikurs' "four goals of misbehavior," are interpreted as a primitive statement of operant principles. Applied techniques long used by Individual Psychology practitioners strongly resemble interventions that applied behavior analysts have developed by more systematic means.

    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. Peacekeeping operations also have the potential to offer opportunities for growth and resilience. India is a major player in peacekeeping activities for well over sixty years all over the world. It is necessary for the commanders and mental health professionals to understand the multifarious factors that impinge on the peacekeeping soldier's mind and the emerging patterns of responses thereof for effective management trained manpower and fulfillment of mission objectives.

  9. The Psychological Assessment in Operational Events

    International Nuclear Information System (INIS)

    Abramova, V.N.; Volkov, E.V.

    1998-01-01

    The possibilities of Psychological Assessment in Operational Events in nuclear power engineering are discussed. The approach of psychology use in quantitative analysis of direct and root causes of operational events is presented. The main attention is paid to the practical method of investigation of an individual who makes an error. The socio-technical system elements can be considered by this method as the external conditions, affecting correctness or errors of actions. The types of errors (violation, mistake, slips) can be clarified. The direct causes of failures and sources of probable root causes of errors also can be defined. Experience shows that the psychological situation of events caused by a human error depends on professional competence, motivation and some professionally important psychological qualities of a person, his functional state, psycho-physiological qualities, characteristics of mentality, attention and memory. In an emergency situation successful personnel performance is mainly effected by such professional qualities as the ability to take the lead in actions, to resolve urgent problems of minimizing the scale of the accident significance; personal participation in dangerous procedures of the accident follow-up, even risking one's life; devotion to one's job; resolute and bold actions; high level of self-control; thoroughness and conscientiousness. External means of activity, influencing the events, include ergonomic characteristics of working place, ergonomics of events technology. External means can be also defined by socio-psychological situation in a group, which refers to the data of social conditions, social-political situation, relationships between people, and by organizational factors.

    2004-01-01

    Mental and physical health of operators of nuclear power plants (NPPs) is directly related to normal and safe operation of NPPs. The cognitive process, volitional character, attention, emotion, feeling and personality are important factors that affect operators' safe behavior. Alcohol, medical drugs and operators' biological rhythm are can also make great effects on their psychological health. By means of job-fitness psychological test, better candidates for operators could be primarily selected from point of psychological view. Psychological follow-up of post skill training, simulator training and practical work of operators can make NPPs prevent from operational accidents due to human errors to the greatest extent. It is helpful for NPPs to find and solve some psychological problems by means of psychological counseling, regulation or psychotherapy. (author)

    In order to identify cognitive error mechanisms observed in the dynamic operational environment, the following materials were analyzed giving special attention to psychological biases, together with possible cognitive tasks and these location, and internal and external performance shaping factors: (a) 13 human factors analyses of US nuclear power plant accidents, (b) 14 cases of Japanese nuclear power plant incidents, and (c) 23 cases collected in simulator experiments. In the resulting analysis, the most frequently identified cognitive process associated with error productions was situation assessment, and following varieties were KB processes and response planning, all of that were the higher cognitive activities. Over 70% of human error cases, psychological bias was affecting to cognitive errors, especially those to higher cognitive activities. In addition, several error occurrence patterns, including relations between cognitive process, biases, and PSFs were identified by the multivariate analysis. According to the identified error patterns, functions that an operator support system have to equip were discussed and specified for design base considerations. (author)

    The paper gives a survey of the development of the negotiationes that have taken place from the beginning 1976 between representatives of BMI and VDWE to examine whether psychological qualification examinations for the shift personal of nuclear power plants will be appropriate. As a result it is shown that first- and reexaminations shall be carried out according principle 25, the psychological part of this examination should, however, be renounced to a still pending standardisation and testing. The more detailed examination of the sense organs, proposed on this occasion, will be defined by the representatives of VDEW by a new proposal. The routine psychological judgement along with a documentation of the superiors is, however, not considered suitable.

    The safe production of electricity by nuclear power plants has been the focus of considerable attention. Much of this concern has been focused on equipment and procedural issues, with less attention to the psychological factors that affect the operations staff of the plants, i.e., those individuals who are most directly responsible for a plant's operations. Stress and type A qualities would be significant for these individuals because of their relationships to job performance and health. Of equal significance would be work-related factors, such as job involvement and work pressure. Also of interest would be hostile tendencies because of the need for cooperation and communications among operations staff. Two variables could influence these psychological factors. One is the degree of responsibility for a plant's nuclear reactors. The individuals with the greatest responsibility are licensed by the US Nuclear Regulatory Commission (NRC). There are also individuals with less direct responsibilities who are not licensed. A second variable is the operating status of the plant, whether or not the plant is currently producing electricity. Relative to ensuring the safe operation of nuclear power plants, these data suggest a positive view of licensed operators. Of interest are the greater stress scores in the licensed staff of the operating plant in contrast with their peers in the nonoperating plant

    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.

    The Socratic function of single case studies (SCSs) is described in its relation to the problem of scientific theory development. Contrary to the traditional point of view, the single case study is not a demonstration or verification of theoretical concepts, but a method of their generation and opportunity for analysis of their interrelations. Considering the case study from the perspective of the Socratic function brings to light important conclusions about the ecological validity of theory development. The essential features of the Socratic function are illustrated using the example of the famous Romantic Essays of Alexandr Luria. © 2015 The Institute of Psychology, Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.

    2015-08-30

    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.

    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.

    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.

  1. Psychology as science and as discipline: the case of Germany.

    Science.gov (United States)

    Gundlach, Horst

    2006-01-01

    This paper examines the history of psychology in Germany. It directs attention to the salient role played by examination regulations in the development of psychology. To highlight this, the term "discipline" is employed not as a synonym of "science" but according to its original meaning, as denoting a social entity consisting of teachers, disciples, more or less canonised subject matters, examinations, and resulting changes of the social status of the examinee. In the early nineteenth century a succession of state rescripts and regulations introduced to university curricula an examination subject named psychology, thereby making psychology an obligatory subject of university lectures, and creating a discipline of psychology next to the science of psychology. The two were far from being identical. This situation, thus far neglected in historiography, profoundly influenced the further development of psychology in Germany.

    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.

    An extensive review of literature on individual and group performance and decisionmaking under psychological stress was conducted and summarized. Specific stress-related variables relevant to reactor operation were pinpointed and incorporated in an experiment to assess the performance of reactor operators under psychological stress. The decisionmaking performance of 24 reactor operators under differing levels of workload, conflicting information, and detail of available written procedures was assessed in terms of selecting immediate, subsequent, and nonapplicable actions in response to 12 emergency scenarios resulting from a severe seismic event at a pressurized water reactor. Specific personality characteristics of the operators suggested by the literature to be related to performance under stress were assessed and correlated to decisionmaking under stress. The experimental results were statistically analyzed, and findings indicated that operator decisionmaking under stress was more accurate under lower levels of workload, with the availability of detailed procedures, and in the presence of high conflicting information

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

    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.

    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.

    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.

    2015-01-01

    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.

  12. Psychophysiological and psychological criteria for professional selection of reactor operators - a review

    International Nuclear Information System (INIS)

    Jonkova, A.

    1992-01-01

    The professional activity of reactor operators is determined according to some modern classification schemes. The NPP operation staff's classification containing groups of operators-supervisors, operators-manipulators and operators-managers (Zinchenko and Munipov) is discussed. The author specifies the functions of the operators-supervisors in more detail. The requirements for selection of operators are given and the significance of mind, memory, attention, differentiative sensomotorics, emotional and stress-stability is emphasized. An own set of criteria for professional selection of reactor operators is proposed based on the definition of reliability concepts -adequacy, timeliness and lack of outages. The requirements for psychological structure of personality are well-grounded also by the collective character of this kind of professional activity also. 28 refs., 1 fig. (A.B.)

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.

    2014-05-01

    The failure to recognize the programmatic similarity between (post-)Kantian German philosophy and early psychology has impoverished psychology's historical self-understanding to a great extent. This article aims to contribute to recent efforts to overcome the gaps in the historiography of contemporary psychology, which are the result of an empiricist bias. To this end, we present an analysis of the way in which Hermann von Helmholtz's theory of perception resonates with Johann Gottlieb Fichte's Ego-doctrine. It will be argued that this indebtedness is particularly clear when focusing on the foundation of the differential awareness of subject and object in perception. In doing so, the widespread reception of Helmholtz's work as proto-positivist or strictly empiricist is challenged, in favor of the claim that important elements of his theorizing can only be understood properly against the background of Fichte's Ego-doctrine.

  20. Olfactory memory: a case study in cognitive psychology.

    Annett, J M

    1996-05-01

    Over the last decade, interest in the general applicability of psychological research has increased significantly, leading to doubts among some critics of cognitive psychology regarding the usefulness of the modern information-processing approach. In particular, current cognitive models of memory address mainly visual and verbal information processing, with little acknowledgement of the existence of other sensory modalities. However, since the mid-1970's, the literature on olfactory memory has expanded rapidly, and it has remained relatively independent of mainstream memory research. This article outlines the olfactory literature, which has focused principally on examination of the Proustian characteristics of smell. The relationship between olfactory and other types of memory is also examined. The author notes that there is evidence that models of memory intended to be general have taken insufficient account of findings from olfaction and other sensory modalities, an approach that could be considered symptomatic of dangerous tendency to base purportedly general theories on databases that are too narrow.

    Despite the wide spread use of operant conditioning within marine animal training, relatively little is known about this unique application of behavioral technology. This article explores the expansion of operant psychology to commercial marine animal training from 1955 to 1965, specifically at marine parks such as Marine Studios Florida, Marineland of the Pacific, Sea Life Park, and SeaWorld. The contributions of Keller and Marian Breland and their business Animal Behavior Enterprises (ABE) as well as other early practitioners of behavioral technology are reviewed. We also describe how operant technology was introduced and formalized into procedures that have become the cornerstone of marine animal training and entertainment. The rapid growth of the marine park industry during this time was closely linked to the spread of behavioral technology. The expansion of operant training methods within marine animal training is a unique success story of behavioral technology. © 2014 Wiley Periodicals, Inc.

    Since 1999, we have reported mild trigonocephaly with symptoms mainly accompanied with developmental delays. We would like to report the operative results of 300 patients. All patients had some kind of clinical symptoms. The diagnosis made recognizing ridge of the fused metopic suture by palpation and a three-dimensional computed tomography (3D-CT). Most patients (287 among 300) could not be diagnosed because of the mild changes of their facial features and their natural development as infants. They suffered from symptoms such as mental retardation, delayed language development, hyperactivity, autistic tendencies, panic and irritability, motor dysfunctions, self-mutilation and sleeping disturbances. Two hundred thirteen patients were recorded intracranial pressure (ICP). Developmental quotients (D.Q) were also measured. Two hundred fifteen (73.6%) of 292 patients with delays of language development were improved within a year after surgery. Other symptoms also improved: 91.6% in hyperactivity, 76.5% in autistic tendencies, 92% in panic, 90.4% in motor dysfunctions, 88.6% in self-mutilation and 93% in sleeping disturbances. The chronological scores in D.Q maintained parallel in most patients. Measurements of ICP resulted in 10 cases (5%) under mean 10 mmHg, 33 cases (15%) between 11 to 15 mmHg and 170 cases (80%) over 16 mmHg. The mean pulse pressure calculated around 9 mmHg in each group. Decompressive cranioplasty was applied to all patients. Patients with mild trigonocephaly may have a possibility to show clinical symptoms. Since the ICP seems to be high, decompressive cranioplasty may be a reasonable treatment for these patients.

    2016-01-01

    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.

    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.

    Abstract Background Under the current ethical and legal standards physicians are expected to breach confidentiality when a third party is at risk. However, the law has mainly focused on risk of bodily harm and there is no legal guidance on physicians’ responsibilty when it comes to risk of psychological harm to a potential targeted victim Methods This case report illustrates a clinical dilemma on duty to warn for mental health professionals. Results N/A Discussion This case report illustrates an unconventional perspective on a psychiatrist’s duty to warn: consideration of risk of psychological harm to the potential target of their patient. Psychological trauma can have a potential negative impact on victims, affecting their mental health and well being as well as their physical health. The ethicolegal dilemma discussed in this case has implications for policies related to the care of psychiatric patients.

  12. Self-castration by a transsexual woman: financial and psychological costs: a case report.

    2012-04-01

    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.

    2014-03-01

    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.

    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 biologic...

    Attachment patterns and personality dimensions have always been considered important to the development and adaptation of the individual. The first aim of this article was to address some basic questions about the place of attachment in a multimethod assessment when compiling a complete picture of the patient's personality functioning. The second aim was to present the Adult Attachment Projective Picture System (AAP; George & West, 2001) as a valid and productive assessment measure. Based on a single case study of an anorexic young woman, the article demonstrates how the AAP is integrated with the Rorschach Comprehensive System (Exner, 1991, 1993) and other assessment tools in both the assessment and in developing a treatment plan.

    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.

    Krause-Kjær, Elisa; Nedergaard, Jensine I

    2015-09-01

    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.

    Although enormous progress has been made in recent years in the field of haemophilia, some problems still await solution, such as the risk of sudden haemorrhage, the sequelae of haemophilic arthropathy and social activities. We, therefore, carried out a case-control study in which some psychological dimensions (social expectations, tendency to depression, state of anxiety and self-esteem) were evaluated in a group of 60 haemophiliacs. A control group was formed of 78 healthy subjects matched for age, socio-economic class and level of education. The methodology used was the administration of self-assessment questionnaires which investigate and provide a quantitative measure of psychological dimensions. The results can be subjected to statistical analysis. Three self-assessment questionnaires were used: (i) the Marlowe-Crowne scale, (ii) the Beck Inventory version modified by Cusinato and (iii) the S.T.A.I.-form. Our aim was to evaluate: (i) whether there are significant differences in the considered psychological aspects between haemophiliacs and healthy subjects; (ii) whether there is a significant correlation between the psychological dimensions considered in the haemophiliacs and in the healthy subjects. The results showed that the haemophiliacs have a good psychological adaptation to their disease with the exception of their greater tendency to have less self-esteem than do the healthy subjects. As far as concerns the second aim, we found than self-esteem correlated with all the psychological variables investigated. This information could indicate the enormous importance that the psychological variable 'self-esteem' plays in haemophiliacs with respect to whether or not they develop depressive disorders and/or anxiety states.

    Previous studies in Euro-American populations have shown that women with polycystic ovarian syndrome (PCOS) have increased levels of "psychological burden". While PCOS has been reported in Arab countries such as Oman, there is a dearth of studies of the occurrence of psychological burden among PCOS women in the Arab region. This study aimed to compare sociodemographic and clinical characteristics of PCOS women diagnosed with non-PCOS women and prevalence of severity of depression, anxiety and stress and to explore the association between PCOS and indices of psychological disturbances after adjusting for potential confounding factors. This hospital-based case-control study was conducted among women aged 16-49 years. The study included 52 women diagnosed with PCOS (as per Rotterdam 2003 criteria) and 60 control who were PCOS-free. The presence of psychological burden - depression, anxiety and stress - was quantified using Depression, Anxiety and Stress Scale-21 (DASS-21). The crude odds ratios (ORs) generated by logistic regression models indicated an increased risk of depression, anxiety and stress among women with PCOS compared to controls. The adjusted OR also indicated an increased risk of depression (OR =1.10; 95% confidence interval [CI] 0.50, 2.43), anxiety (OR =1.09; 95% CI 0.47, 2.52) and stress (OR =1.45; 95% CI 0.68, 3.12), However, no statistical differences were observed along the three psychological distresses ( p >0.05) between the two study groups. The study indicates that the presence of PCOS is associated with an increased risk of psychological burden. If this study will withstand further scrutiny, meeting psychological needs of such population would need to be contemplated.

  11. Warrior Resilience Training in Operation Iraqi Freedom: combining rational emotive behavior therapy, resiliency, and positive psychology.

    Science.gov (United States)

    Jarrett, Thomas

    2008-01-01

    Warrior Resilience Training (WRT) is an educational class designed to enhance Warrior resilience, thriving, and posttraumatic growth for Soldiers deployed in Operation Iraqi Freedom. Warrior Resilience Training uses rational emotive behavior therapy (REBT), Army leadership principles, and positive psychology as a vehicle for students to apply resilient philosophies derived from Army Warrior Ethos, Stoic philosophy, and the survivor and resiliency literature. Students in WRT are trained to focus upon virtue, character, and emotional self-regulation by constructing and maintaining a personal resiliency philosophy that emphasizes critical thinking, rationality, virtue, and Warrior Ethos. The author, an Army licensed clinical social worker, executive coach, REBT doctoral fellow, and former Special Forces noncommissioned officer, describes his initial experience teaching WRT during Operation Iraqi Freedom to combat medics and Soldiers from 2005 to 2006, and his experience as a leader of a combat stress control prevention team currently in Iraq offering mobile WRT classes in-theater. Warrior Resilience Training rationale, curriculum, variants (like Warrior Family Resilience Training), and feedback are included, with suggestions as to how behavioral health providers and combat stress control teams might better integrate their services with leaders, chaplains, and commands to better market combat stress resiliency, reduce barriers to care, and promote force preservation. Informal analysis of class feedback from 1168 respondents regarding WRT reception and utilization is examined.

  12. A case study in Gantt charts as historiophoty: A century of psychology at the University of Alberta.

    Science.gov (United States)

    Dawson, Michael R W

    2013-05-01

    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.

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

    2017-12-09

    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.

  15. Causality in criminal forensic and in civil disability cases: Legal and psychological comparison.

    Science.gov (United States)

    Young, Gerald

    2015-01-01

    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.

    2009-10-01

    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.

  18. Single-Case Research Methods: History and Suitability for a Psychological Science in Need of Alternatives.

    Science.gov (United States)

    Hurtado-Parrado, Camilo; López-López, Wilson

    2015-09-01

    This paper presents a historical and conceptual analysis of a group of research strategies known as the Single-Case Methods (SCMs). First, we present an overview of the SCMs, their history, and their major proponents. We will argue that the philosophical roots of SCMs can be found in the ideas of authors who recognized the importance of understanding both the generality and individuality of psychological functioning. Second, we will discuss the influence that the natural sciences' attitude toward measurement and experimentation has had on SCMs. Although this influence can be traced back to the early days of experimental psychology, during which incipient forms of SCMs appeared, SCMs reached full development during the subsequent advent of Behavior Analysis (BA). Third, we will show that despite the success of SCMs in BA and other (mainly applied) disciplines, these designs are currently not prominent in psychology. More importantly, they have been neglected as a possible alternative to one of the mainstream approaches in psychology, the Null Hypothesis Significance Testing (NHST), despite serious controversies about the limitations of this prevailing method. Our thesis throughout this section will be that SCMs should be considered as an alternative to NHST because many of the recommendations for improving the use of significance testing (Wilkinson & the TFSI, 1999) are main characteristics of SCMs. The paper finishes with a discussion of a number of the possible reasons why SCMs have been neglected.

    2017-01-01

    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.

    Abuse has been considered a significant factor on the development of functional gastrointestinal disorders (FGID), especially for severe and treatment-refractory patients. The aim of our study was to evaluate the presence of all FGID according to Rome II criteria, in a group of women with history of physical, psychological and/or sexual abuse. A cross sectional study was performed in 96 women (37 +/- 12 years of age) with history of physical, psychological and/or sexual abuse (cases); and 96 open population women (36 +/- 14 years of age) (controls). The following evaluations were administered: Rome II questionnaire, a self-administered instrument to evaluate history of physical (beating), psychological(insults, public humiliation) and/or sexual abuse (rape, coercion), and HAD questionnaire. Among 96 women with history of abuse,91 (95%) reported to have suffered psychological abuse, 72 (75%) physical abuse, and 24 (25%)sexual abuse. Women with history of abuse had a higher prevalence of rumination (6% vs. 0%, p= 0.02), functional heartburn (26% vs. 13%, p =0.04), aerofagia (17% vs. 5%, p = 0.019), irritable bowel syndrome (38% vs. 18%, p = 0.002), fecalin continence (16% vs. 4%, p = 0.01), elevator anisyndrome (5% vs. 0%, p = 0.05), and proctalgia fugax (29% vs. 15%, p = 0.02) compared to controls. There was a positive correlation between anxiety (r = 0.5, p = 0.001) and depression scores(r = 0.45, p = 0.001), and the number of FGID. We demonstrated a high prevalence of FGID among women with history of physical,psychological, and/or sexual abuse. In this association,concomitant anxiety and depression play a significant role.

  1. Treatment of psychological factors in a child with difficult asthma: a case report.

    Anbar, Ran D; Sachdeva, Shagun

    2011-07-01

    Difficult asthma is defined as the persistence of asthma symptoms, abnormal pulmonary function showing airway obstruction, and continued requirement for short-acting bronchodilator therapy, despite adequate treatment with inhaled corticosteroids. It calls for a thorough evaluation of the patient to look into alternate and complicating diagnoses. The authors report a case of a 9-year-old patient with difficult asthma who failed to respond to conventional therapy. Although it was recognized that he had a number of potential medical complicating factors including allergies, chronic sinusitis, and gastroesophageal reflux, a psychological intervention using hypnosis ultimately appeared to help alleviate his symptoms completely. Thus, psychological evaluation and intervention should be considered early in the course of management of a patient with difficult asthma, because it may help avoid time-consuming and expensive investigations of potential complicating factors, and it may yield rapid improvement in the patient's clinical condition.

    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.

    This case study illustrates a participatory framework for confronting critical community health issues using 'grass-roots' research-guided community-defined interventions. Ongoing work in Cambodia has culturally adapted research, theory and practice for particular, local health-promotion responses to HIV/AIDS, alcohol abuse and other challenges in the community of Siem Reap. For resource-poor communities in Cambodia, we recycle such 'older' concepts as 'empowerment' and 'action research'. We re-imagine community health psychology, when confronted with 'critical', life-and-death issues, as adjusting its research and practices to local, particular ontological and epistemological urgencies of trauma, morbidity and mortality.

    Studies have shown that effective diabetes management (and also self-management) can delay or prevent the micro- and macrovascular complications. But sometimes the way of achieving optimal glycemic control can affect quality of patient's life resulting in different fears and other psychological problems. Our clinical case demonstrates type 1 diabetes (T1D) patient with frequent episodes of hypoglycemia, including severe hypoglycemia, and various psychosocial problems. It confirms the importance of doctor's communication skills and necessity of constant collaboration with psychologist in organization of diabetes care.

    Intra-operative Radiation Therapy (IORT) is gaining popularity as an adjuvant option to surgical resection, in treatment of glioblastoma multiforme (GBM) for increasing survival rate, which a highly aggressive cerebral tumor with poor prognosis. Τhe authors plan to investigate the effects of IORT combined with surgical resection on the psychological status of these patients based on tumor location. From December 2013 to February 2017, we have enrolled 109 patients with high grade cerebral gliomas, documented by Magnetic Resonance Spectroscopy (MRS). Patients with previous history of brain surgery or radiation, altered mental status and psychological content and patients diagnosed with metastases were excluded. Demographic data, tumor volume based on pre-operative Magnetic Resonance Imaging (MRI) and psychological status were recorded based on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. The remaining 56 patients, were equally randomized into conventional (surgical resection-group A), and trial (surgical resection with IORT-group B) who underwent IORT using the 50kV INTRABEAM® system (Carl Zeiss Meditec AG, Germany). Psychological profiles of both groups were re-evaluated in the 3 rd post-operative month. Group A consisted of 18 males and 10 females with mean age of 54.4 years, while group B consisted of 16 males and 12 females with mean age of 57.8 years. Tumor volumetry revealed mean 81.52cc and 82.8cc for group A and B respectively. (P value 0.14) Patients were classified based on glioma location on pre-operative MRI: a) left parietal lobe (6 in group A, 5 in group B); b) left temporal lobe (7 in group A, 5 in group B); c) right parietal lobe (5 in group A, 6 in group B); d) left fronto-temporal lobe (4 in group A, 6 in group B); e) left parieto-temporal lobe (4 in group A, 5 in group B); and, f) right frontal lobe (2 in group A, 1 in group B). Group B received mean 8.05 Gy radiation for mean 11.2 minutes. Post-operative

    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

    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.

    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.

    The US Nuclear Regulatory Commission and Sandia National Laboratories sponsored a project to evaluate psychological scaling techniques for use in generating estimates of human error probabilities. The project evaluated two techniques: direct numerical estimation and paired comparisons. Expert estimates were found to be consistent across and within judges. Convergent validity was good, in comparison to estimates in a handbook of human reliability. Predictive validity could not be established because of the lack of actual relative frequencies of error (which will be a difficulty inherent in validation of any procedure used to estimate HEPs). Application of expert estimates in probabilistic risk assessment and in human factors is discussed

    We encountered a rare operative case of hyperthyroidism followed by ulcerative colitis (UC). A 26-year-old mam was referred to our department to undergo an operation. We suspected the possible complication of adrenal insufficiency, since he suffered from severe weight loss, a high fever and palpitation on admission. We diagnosed hyperthyroidism, however, based on the presence of high serum free T3 and T4 levels and a decreased TSH level. After improving the symptoms and the thyroid function by administering thiamazole, we then performed a total proctocolectomy. Although a high rate of association of autoimmune thyroid diseases with UC has been suggested, only 9 cases of hyperthyroidism coexisting with UC have so far been reported in Japan. A common immunological process has been suggested to be implicated in the pathogenesis of this association, however, the exact mechanism needs to be elucidated in the future.

    . Health economic modeling has paid limited attention to the effects that patients' psychological characteristics have on the effectiveness of treatments. This case study tests 1) the feasibility of incorporating psychological prediction models of treatment response within an economic model of type 1 diabetes, 2) the potential value of providing treatment to a subgroup of patients, and 3) the cost-effectiveness of providing treatment to a subgroup of responders defined using 5 different algorithms. . Multiple linear regressions were used to investigate relationships between patients' psychological characteristics and treatment effectiveness. Two psychological prediction models were integrated with a patient-level simulation model of type 1 diabetes. Expected value of individualized care analysis was undertaken. Five different algorithms were used to provide treatment to a subgroup of predicted responders. A cost-effectiveness analysis compared using the algorithms to providing treatment to all patients. . The psychological prediction models had low predictive power for treatment effectiveness. Expected value of individualized care results suggested that targeting education at responders could be of value. The cost-effectiveness analysis suggested, for all 5 algorithms, that providing structured education to a subgroup of predicted responders would not be cost-effective. . The psychological prediction models tested did not have sufficient predictive power to make targeting treatment cost-effective. The psychological prediction models are simple linear models of psychological behavior. Collection of data on additional covariates could potentially increase statistical power. . By collecting data on psychological variables before an intervention, we can construct predictive models of treatment response to interventions. These predictive models can be incorporated into health economic models to investigate more complex service delivery and reimbursement strategies.

  4. A Human Proximity Operations System test case validation approach

    Huber, Justin; Straub, Jeremy

    A Human Proximity Operations System (HPOS) poses numerous risks in a real world environment. These risks range from mundane tasks such as avoiding walls and fixed obstacles to the critical need to keep people and processes safe in the context of the HPOS's situation-specific decision making. Validating the performance of an HPOS, which must operate in a real-world environment, is an ill posed problem due to the complexity that is introduced by erratic (non-computer) actors. In order to prove the HPOS's usefulness, test cases must be generated to simulate possible actions of these actors, so the HPOS can be shown to be able perform safely in environments where it will be operated. The HPOS must demonstrate its ability to be as safe as a human, across a wide range of foreseeable circumstances. This paper evaluates the use of test cases to validate HPOS performance and utility. It considers an HPOS's safe performance in the context of a common human activity, moving through a crowded corridor, and extrapolates (based on this) to the suitability of using test cases for AI validation in other areas of prospective application.

    2017-01-01

    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.

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

    Hammack, Phillip L; Windell, Eric P

    2011-08-01

    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. Simulation of worst-case operating conditions for integrated circuits operating in a total dose environment

    International Nuclear Information System (INIS)

    Bhuva, B.L.

    1987-01-01

    Degradations in the circuit performance created by the radiation exposure of integrated circuits are so unique and abnormal that thorough simulation and testing of VLSI circuits is almost impossible, and new ways to estimate the operating performance in a radiation environment must be developed. The principal goal of this work was the development of simulation techniques for radiation effects on semiconductor devices. The mixed-mode simulation approach proved to be the most promising. The switch-level approach is used to identify the failure mechanisms and critical subcircuits responsible for operational failure along with worst-case operating conditions during and after irradiation. For precise simulations of critical subcircuits, SPICE is used. The identification of failure mechanisms enables the circuit designer to improve the circuit's performance and failure-exposure level. Identification of worst-case operating conditions during and after irradiation reduces the complexity of testing VLSI circuits for radiation environments. The results of test circuits for failure simulations using a conventional simulator and the new simulator showed significant time savings using the new simulator. The savings in simulation time proved to be circuit topology-dependent. However, for large circuits, the simulation time proved to be orders of magnitude smaller than simulation time for conventional simulators

    Objective: To explore the correlation of the anti-stress ability of nuclear power plant operators with their heart rate, blood pressure and mental health. Methods: A total of 136 male nuclear power plant operators received the continuous performance test (CPT) and mental health test (MHT), while 37 male senior students were used as the control group. Heart rate and blood pressure were recorded before and after the test. The nuclear power plant operators were divided to high score group and low score group by CPT scores. The correlation of the anti-stress ability and blood pressure,heart rate and their mental health was analyzed. Results: The scores of CPT and MHT test with the operators were significantly higher than those of the control group (t=-1.25, 6.25, P<0.05). After the test, the heart rate, systolic pressure and diastolic pressure of the operators were all significantly lower than those of the control group (t=-2.07, 3.28, 2.74, P<0.05). The CPT score of the high score group was lower in the heart rate, systolic pressure and diastolic pressure than the low score group (t=-3.15, -2.78, -2.54, P<0.05), while the scores of CPT and MHT were better (t=0.63, 6.90, P<0.05). CPT scores were negatively correlated with the increasing range of the heart rate, systolic pressure and diastolic pressure (r=- 0.69, -0.94, and -0.62, P<0.05), and positively correlated with the MHT scores (r=0.54, P<0.05). Conclusions: To a certain extent, CPT and MHT test can reflect the anti-stress ability and be used as one of the bases to select nuclear power plant operators and to assess their competence.

    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.

  15. Quantum generalized observables framework for psychological data: a case of preference reversals in US elections

    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'.

  16. On the renormalization of operator products: the scalar gluonic case

    Zoller, Max F.

    2016-01-01

    In this paper we study the renormalization of the product of two operators O 1 =−(1/4)G μν G μν in QCD. An insertion of two such operators O 1 (x)O 1 (0) into a Greens function produces divergent contact terms for x→0. In the course of the computation of the operator product expansion (OPE) of the correlator of two such operators i∫ d 4 x e iqx T{ O 1 (x)O 1 (0)} to three-loop order http://dx.doi.org/10.1007/JHEP12(2012)119; http://dx.doi.org/10.1007/JHEP10(2014)169 we discovered that divergent contact terms remain not only in the leading Wilson coefficient C 0 , which is just the VEV of the correlator, but also in the Wilson coefficient C 1 in front of O 1 . As this correlator plays an important role for example in QCD sum rules a full understanding of its renormalization is desireable. This work explains how the divergences encountered in higher orders of an OPE of this correlator should be absorbed in counterterms and derives an additive renormalization constant for C 1 from first principles and to all orders in perturnbation theory. The method to derive the renormalization of this operator product is an extension of the ideas of V. Spiridonov, Anomalous dimension of g μν 2 and β-function, Preprint IYAI-P-0378 (1984). and can be generalized to other cases.

    The purpose of the present nationwide psychological autopsy case-control study is to identify the association between mental disorders and suicide in Japan, adjusting for physical conditions. A semi-structured interview was conducted of the closest family members of 49 suicide completers and 145 gender-, age-, and municipality-matched living controls. The interview included sections of socio-demographic characteristics, physical conditions, and a psychiatric interview producing DSM-IV diagnoses of mental disorders prior to suicide (or at survey). We compared prevalences of mental disorders between the two groups, using conditional logistic regression. A significantly higher proportion with any mental disorder was found in the suicide group (65.3%) compared to the control group (4.8%) (p=0.003, odds ratio [OR]=7.5). The population attributable risk proportion associated with mental disorder was 0.24. Mood disorder, particularly major depressive disorder, was the most strongly associated with suicide (pmental disorders, particularly mood disorder, were significantly associated with a greater risk of suicide in Japan, independent of physical conditions. Mental disorders are a major target of suicide prevention programs in Japan. Copyright © 2012 Elsevier B.V. All rights reserved.

    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.

    Full Text Available Introduction: Embolization prior to surgery can make tumor resection less complicated by reducing blood loss during surgery and shortening the time of the operation. Case report: In this paper, we presented a case of a sixty-three-year-old woman who was admitted to the Clinic of Neurosurgery, Clinical Center Niš, Serbia, at November 2016, after she underwent a CT brain scan that showed a large tumor of the left cerebellopontile angle. Digital subtraction angiography presented a large, highly vascularized tumor lesion that compressed the brain stem. The patient underwent endovascular procedure, and complete embolization of the tumor vessels was established. The radiologist delivered embolization material via the left ascending pharyngeal artery. In the next 24 hours, an operation was performed i.e. radical extirpation surgery (Simpson grade I. Postoperatively, the patient’s GCS was 15, with no new neurological deficit. Postoperative brain CT scan showed neither rest tumor nor blood clot inside the tumor bed. Pathohistological finding revealed atypical meningioma grade II. Conslusion: Despite some clinicians’ dilemma considering the utility of preoperative embolization of meningioma vessels, we believe that a team of educated and dedicated radiologist and neurosurgeon could achieve great results in resection of large and inaccessible cranial tumors.

    Full Text Available Abstract Background In some hypertensive patients, psychological stress makes blood pressure difficult to control and causes physical symptoms such as headache or dizziness. We report the case of a hypertensive man whose psychological stress-induced increase in blood pressure was attenuated by cilnidipine. Case Presentation The patient (a 72-year-old man had hypertension and was on antihypertensive therapy. When mentally concentrating, he experienced occipital headaches and dizziness, and despite thorough testing, no abnormality was found. He was subsequently referred to our department. The mirror drawing test (MDT, a psychological stress test, increased blood pressure by about 40 mmHg, and the patient described occipital headache. Plasma noradrenaline level also increased from 212 to 548 pg/ml. We therefore switched the patient from nifedipine, an L-type calcium (Ca channel blocker, to cilnidipine, an L-type/N-type Ca channel blocker with suppressive effects on sympathetic activity. Cilnipidine attenuated MDT-induced an increase in blood pressure and plasma noradrenaline level and prevented the development of headache during testing. Conclusion These findings suggest that cilnidipine is a useful antihypertensive agent for hypertensive patients in whom psychological stress causes marked fluctuations in blood pressure.

    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.

  4. PSYCHOLOGICAL PROBLEMS AND STRESS FACED BY SOLDIERS WHO OPERATE IN ASYMMETRIC WARFARE ENVIRONMENTS: EXPERIENCES IN THE FIELD

    Directory of Open Access Journals (Sweden)

    Giuseppe CAFORIO

    2014-10-01

    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.

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

    Directory of Open Access Journals (Sweden)

    Nilsen, Håvard

    2008-12-01

    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.

    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.

  7. A case for Acoustic Emission surveillance of operating reactors

    International Nuclear Information System (INIS)

    Hartman, W.F.

    1985-01-01

    In the nuclear power industry, the potential consequences of cracks and leaks, the problems of personnel and public exposure to radiation, are certainly as serious as ever. The costs of repairing advanced damage soar higher every year and the established inspection methods, taken together, still leave some gaps which Acoustic Emission (AE) can potentially close. The intergranular stress corrosion cracking (IGSCC) problem not only poses safety problems, but entails remedies costing the industry billions of dollars. If crack growth could be detected during plant operation, particular welds could be designated as requiring inspection during the next outage. Furthermore, if a highly sensitive, reliable leak-detection capability were applied to the system, any through-wall crack would be instantaneously detected. AE monitoring has the potential for both of these, on-line, in real time. So, there is renewed interest in what AE can do to solve these problems. Reviewing the progress in AE, relevant to nuclear applications, indicates that a strong case can be made for AE surveillance of operating reactors. This progress can be reviewed under two headings: leak detection and crack detection

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

    2015-02-01

    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.

    Full Text Available Background. Since psychological work in the Ministry of Internal Affairs of the Russian Federation is one of the professional activities, the departments must perform the tasks of the following two tiers: professionally-based and system-wide. Those tasks of the first tier perform the tree groups of individual and group diagnostics, personal and professional development, and professional and psychological support. When implemented they are determined by system-wide goals, with the main one shaping the patriotic worldview, corporate culture and the significantprofessionalproperties of the employees. Objective.

    2014-11-01

    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.

    Khalily, Muhammad Tahir

    2011-05-01

    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.

    Full Text Available The banking sector of Yemen is under threat due to the lack of confidence and trust of the prospective clients that hindered economic development of the country. The study aimed to measure a moderating effect of transformational leadership on employees’ psychological empowerment and job satisfaction relationship so that attitudes of the Yemeni can be bumped towards banking. In this study, 160 employees were surveyed in different branches of four banks in Yemen. The data were analyzed in four stages namely, reliability and validity analysis, descriptive analysis, multivariate analysis, and hypotheses testing analysis. The study revealed a significant positive relationship between employees’ psychological empowerment and transformational leadership towards their job satisfaction level. If the policy makers consider the findings and undertake necessary measures, the Yemeni banking is expected to be accelerated which will contribute to the economy of the country.

    We examine operating room productivity on the example of hospitals in Germany with independent anesthesiology departments. Linked to anesthesiology group literature, we use the ln(Total Surgical Time/Total Anesthesiologists Salary) as a proxy for operating room productivity. We test the association between operating room productivity and different structural, organizational and management characteristics based on survey data from 87 hospitals. Our empirical analysis links improved operating room productivity to greater operating room capacity, appropriate scheduling behavior and management methods to realign interests. From this analysis, the enforcing jurisdiction and avoiding advance over-scheduling appear to be the implementable tools for improving operating room productivity.

    Psychological therapies in order to provide cognitive enhancement have gained some momentum the last decades. The goal of this case study was to evaluate the effects of a cognitive enhancement training program on daily living activities, cognition, and depression in a demented elderly participant. A 6-month training program was proposed for the participant, whose overall evaluation results suggest significant deficits impairment but whose response rate to the proposed tasks of the treatment was interestingly high. However, additional research is needed to overall evaluate the efficacy of the proposed method to elderly adults.

    2007-01-01

    A retrospective review was made of 324 operated cases of acute appendicitis for sixteen years from 1989 to 2005. For seven years from 1999 to 2005, an additional review was made of 63 cases where patients visited our department on suspicion of acute appendicitis and received medical treatment without operation. Cases of hospitalization on suspicion of appendicitis averaged 18 a year for 1999 to 2005, with half these being appendicitis or peritonitis due to perforated appendicitis. The number of cases by age groups for those with acute appendicitis reached 25 per year in 1997 but fell off from 1998 onwards. Out of the total 324 cases, 179 were boys, 145 were girls, and there were 188 cases of acute appendicitis and 136 cases of perforated appendicitis. There were 23 cases of catarrhal appendicitis, with three cases out of the 63 cases overall of the last seven years. There were 66 cases for ages 0 to 6, 168 cases for ages 7 to 11, and 90 cases for ages 12 to 20, the peak age group being 7 to 11. Perforated appendicitis occurred in 65.2% of cases involving infants under six, which is relatively high compared to the 36.0% of the over seven age grouping. There were 112 cases of fecalith out of the 324 overall cases, 24.5% of acute appendicitis cases and 48.5% of perforated appendicitis cases. Over the last seven years ultrasound examination made visible the inflamed appendix in 41 cases of 46 (89.1%) for acute appendicitis and in 16 cases of 17 (94.1%) for perforated appendicitis. CT scans were used in five cases of acute appendicitis/perforated appendicitis out of the 324 overall cases. Five of the 63 cases of surgical operations from 1999 to 2005 involved surgery made after diagnosis of acute appendicitis after follow-up hospitalization. Types of operations involved 11 cases of laparoscopic appendectomy, the remaining 313 operations involving classical open appendectomy. (author)

    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.

    Full text: Under the auspices of its RTD (Research and Technological Development) Framework Programmes, the European Commission has supported the development of the RODOS (Real-time On-line DecisiOn Support) system for off-site emergency management after nuclear accidents since the end of 1989. Significant additional funds have been provided by many national RTD programmes, research institutes and industrial collaborators. In particular, the German Ministry of Environment, Nature Conservation and Reactor Safety (BMU) financially contributed to the project with emphasis an early emergency response. The ongoing RTD work under the EC's 5 th Framework Programme lead to significant extensions, modifications and new developments of both the system and the application software integrated in the RODOS system. All new functions and software components, which have been successfully tested, build the content of RODOD version PV5.0, which has been released in April 2003. One of the new key features of the RODOS system is its capability to deal with release scenarios longer than 24 hours in all its modes of application: in automatic use, the release duration is unlimited; for interactive calculations, the release has to be limited to 47 days. The environmental contamination and the corresponding doses are calculated on a daily basis and add up to get the total values. When calculating early emergency actions (such as sheltering, administration of stable iodine tablets, and evacuation), the time sequence of potential doses from previous days are used to determine weather a certain intervention level has been or will be exceeded at any time during the release and, in that way, to define areas where potential actions might have been initiated in the past. In case of long term countermeasures, the user has been given the option to consider a number of countermeasures which could be implemented during the release phase. This has increased the flexibility of the module for those

  17. Minors, Moral Psychology, and the Harm Reduction Debate: The Case of Tobacco and Nicotine.

    Science.gov (United States)

    Kozlowski, Lynn T

    2017-12-01

    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.

    2017-10-01

    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

    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.

    Much waste arises from operating rooms (ORs). We estimated the practical and financial feasibility of an OR recycling program, weighing all waste from 6 ORs in Melbourne, Australia. Over 1 week, 237 operations produced 1265 kg in total: general waste 570 kg (45%), infectious waste 410 kg (32%), and recyclables 285 kg (23%). The achieved recycling had no infectious contamination. The achieved recycling/potential recycling rate was 285 kg/517 kg (55%). The average waste disposal costs were similar for general waste and recycling. OR recycling rates of 20%-25% total waste were achievable without compromising infection control or financial constraints.

    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

    In spite of great progress in surgical treatment of anorectal malformations, fecal incontinence is still, in variable degrees, a frequent and unpleasant postsurgical sequela. The most frequent causes of incontinence are: 1) the incorrect placement of the pulled-through colon in the levator ani and sphincteric muscular complex during abdomino-perineal surgical procedures; 2) the poor development of sphinteric musculature; 3) the associated sacral anomalies. Postoperative CT helps to evaluate all the above-mentioned conditions, in view of possible new surgical procedure for improving continence (besides postoperative CT can help in choosing the more suitable surgical technique). Nine patients, aged 3 to 13 years (2 with good continence and 7 with various degrees of incontinence), were studied with pelvic postoperative CT. In the cases (2) with good continence the CT picture was: good development of sphincteric musculature and neo-anorectum correctly placed into sphinteric musculature; in the cases (3) with low degree of continence: neoanorectum correctly placed, but hypoplasic puborectal muscle; in the case (4) with complete incontinence, neo-anorectum incorrectly placed and poor development of sphinteric musculature. A further Posterior Sagittal Anorectoplasty (according Pena) is only suitable in the incontinence cases with: 1) neo-anorectum seriously misplaced; 2) good development of sphinteric musculature; 3) absence of sacral anomalies. Postoperative CT is a valid mean for demostrating all the above-mentioned conditions and for chooosing the best surgical technique in each case

    Full Text Available As the belief of the beholder in an exchange about the obligations that another party should have, interorganizational psychological contract (IPC from a micro perspective provides a new angle to study interorganizational relationship (IOR. This paper studies the interrelation and coevolution of IORs and IPCs by building a system dynamics (SD model. Firstly based on the structural analysis of the interrelations of IPC and IOR, this paper builds the qualitative causal loop diagram of the interrelations. Based on investigation of 55 manufacturing enterprises in China we further draw the stock and flow diagram. Then we apply the data of Jiangxi Motors Co., Ltd., to simulate the model. The results reveal the development and evolution of IORs and IPCs and their interrelations. Furthermore, the sensitivity analysis is conducted and the influences of trust on IORs and IPCs are discussed. Finally managerial implications and some recommendations are provided for the decision-making of developing IORs.

    2011-06-01

    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

  10. The clinical psychology of Lightner Witmer: a case study of institutional innovation and intellectual change.

    Science.gov (United States)

    O'Donnell, J M

    1979-01-01

    The name Lightner Witmer is rarely invoked in the historian's litany of psychological saints. Neither a grand systematizer nor an ardent experimentalist, the "world's first clinical psychologist" is even dismissed by contemporary clinicians because of his purported failure to achieve for psychologists professional hegemony over the "problem child." Yet disciplinary ventures which in Joseph Ben-David's phrase fail to "take off" represent extremely illuminating indicators of a discipline's shifting ideas, roles, and aspirations. Explicitly urging that historians pay more attention to subgroups of larger disciplines, this paper constitutes an attempt to assess the impact of changing social roles upon psychologists' intellectual stances through an examination of Witmer's novel activities at the University of Pennsylvania.

  11. A case of undeclared debt? Claude Lévi-Strauss' ambiguities and paradoxes toward analytical psychology.

    2018-06-09

    If his relationship to Sigmund Freud's psychoanalysis has been widely acknowledged, Claude Lévi-Strauss' rapport with C.G. Jung's analytical psychology remains quite obscure. While secondary commentary has been abundant, its approach has above all been intertextual, to the detriment of a rigorously historical reading. Even if certain arguments put forward by supporters of so-called "influence" deserve to be taken into account, especially because they highlight Lévi-Strauss ambiguities and paradoxes toward Jung, this paper provides proof that a precise reading of the texts, with the help of recent studies on the intellectual genesis of Lévi-Strauss, lead to reject the thesis of an unstated debt owed by the French anthropologist to the Zurich psychologist. © 2018 Wiley Periodicals, Inc.

    2016-03-01

    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.

    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.

    2016-03-10

    The Acute Psychological Trauma (APT) Study was a collaboration between an acute care hospital, a specialized multidisciplinary program designed to meet the mental health needs of injured workers, and a large urban public transit system. The overall purpose was to evaluate a Best Practices Intervention (BPI) for employees affected by acute psychological trauma compared to a Treatment as Usual (TAU) group. The specific purpose is to discuss facilitators and barriers that were recognized in implementing and carrying out mental health research in a workplace setting. Over the course of the APT study, a joint implementation committee was responsible for day-to-day study operations and made regular observations on the facilitators and barriers that arose throughout the study. The facilitators to this study included the longstanding relationships among the partners, increased recognition for the need of mental health research in the workplace, and the existence of a community advisory committee. The significant barriers to doing this study of mental health research in the workplace included differences in organizational culture, inconsistent union support, co-interventions, and stigma. Researchers and funding agencies need to be flexible and provide additional resources in order to overcome the barriers that can exist doing workplace mental health research.

    Hungary became a Member of the IAEA in 1957 and has participated in the programme of technical assistance and co-operation from its start in 1958. By the end of 1976, Hungary ranked as the fifteenth largest recipient of IAEA technical assistance. Since then, there has been a significant increase in overall technical co-operation activities, and by the end of 1988 a total of over US $9.5 million of assistance had been received by Hungary, making it the fifth largest recipient of all Member States. In view of this situation, a special evaluation review was carried out in 1989 of the IAEA's technical co-operation programme in Hungary over the period 1976-1989. This evaluation review has shown that, simultaneously with the increase in the IAEA's support, there has been a rapid development in Hungary of the national nuclear infrastructure and this has permitted the country to absorb and utilize the assistance provided to the maximum extent. 7 figs

  19. Participation, Poverty and Public Policies: 3P Challenging Community Environmental Psychology (The Case of the Communal Councils in Venezuela

    2012-12-01

    Full Text Available Participation, poverty and public policy are three relevant topics for the state, society and academy, particularly for environmental and community social psychology. Meanings and ways of addressing these topics by the above mentioned sector have varied across time and places. Recent impact of new governance models, such as participative democracy, has provoked changes in public policy modes of influence, as a strategy for poverty reduction. Such changes’ orientations coincide with those of environmental community psychology, social constructionist theoretical perspective and qualitative methodology. In Venezuela, only Latin American country where participation has been given a constitutional and legal status, it is important to study participation’s meanings and its implications in public management as a strategy for poverty reduction. Communal councils constitute the main community participatory structure, which integrates poor sectors and vehicles their requirements together with governmental entities. Conscious as we are of existing gaps between discourses and actions, the present research analyses official discourses on participation, through the Venezuelan Constitution and the Organic Communal Councils Law, and compares them with participatory meanings and experiences provided by communal councils’ members and other community stakeholders’ narratives. Results show differences between official and community perspectives on participation in communal councils, as well as discrepancies within communities: they also point out to the difficulties of state induced participation, as is the venezuelan case, for its protagonists’ limitations for transcending projects and exerting power outside community boundaries.

    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.

    Citation rates and impact factors are often used in an attempt to evaluate the apparent prestige of scholarly journals and the quality of research published by individual scholars. However, the apparent prestige of "top tier" journals may reflect aggressive marketing and advertising efforts as much as scholarship. Some journals have retained their independence from professional organizations and the funding, marketing, and advocacy policies that may be associated with such organizations. While lacking as much visibility as organizational journals and sometimes considered "lower tier," independent journals may be able to provide comparable scientific quality as measured by citation rates. To test this, the citation rates of 169 articles published by a frequently cited scholar were compared across first- and second-tier journals, including many sponsored and marketed by large professional organizations, and to rates for two independent journals combined, Psychological Reports and Perceptual and Motor Skills. Citation rates were higher for first-tier journals but for most comparisons, especially those that controlled for heterogeneity of variance, results did not differ in statistically significant ways among the three tiers of journals, though some nonsignificant trends (p journals appear to be a relatively weak indicator of scientific merit; journals at any tier contain articles that are useful and of good quality.

    2015-04-01

    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

    The rapid growth in data centres - large computing infrastructures containing vast quantities of data processing and storage equipment - has resulted in their consumption of up to 100 times more energy per square metre than office accommodation. The decrease in processing server sizes and the more efficient use of space and server processing are challenging data centre facilities to provide more power and cooling, significantly increasing energy demands. Energy consumption of data centres can be severely and unnecessarily high due to inadequate localised cooling and densely packed server rack layouts. However, as heat dissipation in data centres rises by orders of magnitude, inefficiencies such as air recirculation causing hot spots and flow short-circuiting will have a significant impact on the thermal manageability and energy efficiency of the cooling infrastructure. Therefore, an efficient thermal management of high-powered electronic equipment is a significant challenge for cooling of data centres. To highlight the importance of some of these issues, in this project, an operational data centre has been studied. Field measurements of temperature have been performed. Numerical analysis of flow and temperature fields is conducted in order to evaluate the thermal behaviour of the data centre. A number of undesirable hot spots have been identified. To rectify the problem, a few practical design and remedial solutions to improve the cooling effectiveness have been proposed and examined to allow a reduced air-conditioning power requirement. The findings lead to a better understanding of the cooling issues and the respective proposed solutions allow an improved design for future data centres. - Highlights: → Study of flow and temperature distribution in an operational data centre. → Both field measurements and numerical simulations are conducted. → Numerical simulations are validated by field measurements. → Various modifications to improve the thermal

  12. New classification of operators' human errors at overseas nuclear power plants and preparation of easy-to-use case sheets

    International Nuclear Information System (INIS)

    Takagawa, Kenichi

    2004-01-01

    At nuclear power plants, plant operators examine other human error cases, including those that occurred at other plants, so that they can learn from such experiences and avoid making similar errors again. Although there is little data available on errors made at domestic plants, nuclear operators in foreign countries are reporting even minor irregularities and signs of faults, and a large amount of data on human errors at overseas plants could be collected and examined. However, these overseas data have not been used effectively because most of them are poorly organized or not properly classified and are often hard to understand. Accordingly, we carried out a study on the cases of human errors at overseas power plants in order to help plant personnel clearly understand overseas experiences and avoid repeating similar errors, The study produced the following results, which were put to use at nuclear power plants and other facilities. (1) ''One-Point-Advice'' refers to a practice where a leader gives pieces of advice to his team of operators in order to prevent human errors before starting work. Based on this practice and those used in the aviation industry, we have developed a new method of classifying human errors that consists of four basic actions and three applied actions. (2) We used this new classification method to classify human errors made by operators at overseas nuclear power plants. The results show that the most frequent errors caused not by operators themselves but due to insufficient team monitoring, for which superiors and/or their colleagues were responsible. We therefore analyzed and classified possible factors contributing to insufficient team monitoring, and demonstrated that the frequent errors have also occurred at domestic power plants. (3) Using the new classification formula, we prepared a human error case sheets that is easy for plant personnel to understand. The sheets are designed to make data more understandable and easier to remember

    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.

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

    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

    With lots of references for 4-blade bulb turbines, such as these of Wu Jin Xia (4 units – 36.1 MW per unit – 9.2 m rated head), Chang Zhou (15 units – 46.7 MW per unit – 9.5 m rated head) and Tong Wan (4 units – 46.2 MW per unit – 11 m rated head), ALSTOM Power Hydro is one of the major suppliers of bulb turbines operating under medium head for the Chinese market. ALSTOM Power Hydro has been awarded in November 2010 a contract by Jiang Xi Province Xia Jiang Water Control Project Headquarters to equip Xia Jiang's new hydropower plant. The power dam is located on the Gan Jiang river, at about 160 km away from Nan Chang town in South Eastern China. The supply will consist in 5 bulb units including the furniture of both the turbine and its generator, for a total capacity of 200 MW, under a rated net head of 8.6 m. The prototype turbine is a 7.8 m diameter runner, rotating at 71.4 rpm speed. For this project, ALSTOM has proposed a fully new design of 4-blade bulb runner. This paper outlines the main steps of the hydraulic development. First of all, a fine tuning of the blade geometry was performed to enhance the runner behaviour at high loads and low heads, so that to fulfill the demanding requirements of efficiencies and maximum output. The challenge was also to keep an excellent cavitation behaviour, especially at the outer blade diameter in order to avoid cavitation erosion on the prototype. The shape of the blade was optimized by using the latest tools in computational fluid dynamics. Steady state simulations of the distributor and the runner were performed, in order to simulate more accurately the pressure fields on the blade and the velocity distribution at the outlet of the runner. Moreover, draft tube computations have been performed close to the design point and at higher loads. Then, a model fully homologous with the prototype was manufactured and tested at ALSTOM's laboratory in Grenoble (France). The model test results confirmed the predicted

    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.

    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.

  19. Adverse physiological and psychological effects of screen time on children and adolescents: Literature review and case study.

    A growing body of literature is associating excessive and addictive use of digital media with physical, psychological, social and neurological adverse consequences. Research is focusing more on mobile devices use, and studies suggest that duration, content, after-dark-use, media type and the number of devices are key components determining screen time effects. Physical health effects: excessive screen time is associated with poor sleep and risk factors for cardiovascular diseases such as high blood pressure, obesity, low HDL cholesterol, poor stress regulation (high sympathetic arousal and cortisol dysregulation), and Insulin Resistance. Other physical health consequences include impaired vision and reduced bone density. Psychological effects: internalizing and externalizing behavior is related to poor sleep. Depressive symptoms and suicidal are associated to screen time induced poor sleep, digital device night use, and mobile phone dependency. ADHD-related behavior was linked to sleep problems, overall screen time, and violent and fast-paced content which activates dopamine and the reward pathways. Early and prolonged exposure to violent content is also linked to risk for antisocial behavior and decreased prosocial behavior. Psychoneurological effects: addictive screen time use decreases social coping and involves craving behavior which resembles substance dependence behavior. Brain structural changes related to cognitive control and emotional regulation are associated with digital media addictive behavior. A case study of a treatment of an ADHD diagnosed 9-year-old boy suggests screen time induced ADHD-related behavior could be inaccurately diagnosed as ADHD. Screen time reduction is effective in decreasing ADHD-related behavior. Components crucial for psychophysiological resilience are none-wandering mind (typical of ADHD-related behavior), good social coping and attachment, and good physical health.

    The Accreditation Council for Graduate Medical Education (ACGME) modified the designation of major (index) operative cases to include those previously considered "minor." This study assessed the potential effect of these changes on resident operative experience. With Institutional Review Board approval, we analyzed National Surgical Quality Improvement Program participant use files for 2005-2008 for general and vascular surgery cases. Primary CPT case coding was mapped to the ACGME major case category using both the old and new classification schemes. The variables were analyzed using χ(2) analysis in SPSS IBM 19 (IBM, Armonk, New York). A total of 576,019 cases were reviewed. Major cases as defined by the new classification represented an increasing proportion of the cases each year, rising from 88.3% in 2005 to 95% by 2008 (p top procedures to include excision of breast lesion (22,175 [12.7%]), laparoscopic gastric bypass (18,825 [10.8%]), ventral hernia repair (14,732 [8.5%]), and appendectomy (10,190 [5.9%]). Of these newly designated major cases, the proportion not covered by residents increased from 22% in 2005 to 44% in 2007 and 2008 (p quality.

    In the early years of the Atomic Age, radiation accidents or exposure was limited to laboratories or facilities. After the major accidents at TMI, Goainia, Chernobyl, when a large proportion of the population were exposed, interest in the psychosocial aspects has developed. In order to understand the psychological impact, an understanding of the causation of symptoms is necessary. Stress, anxiety, fear, physiological correlates and psychological consequences are thus explained. The different clinical entities and the ways and means of tackling them are described. Further, 'psychological first aid' and ameliorating measures are discussed too. Finally, prevention of psychological impact including education, community support, information dissemination etc. is described. (author)

    1998-01-01

    Objective: To perform retrospective analysis of 49 operated patients with histologically proven spondylodiscitis of tbc and pyogenic origin. Patient histories, laboratory tests and radiographic findings were statistically compared between two groups. We estimated that in 16 cases (32.6%) origin of spondylodiscitis was tbc and 33 cases (67.4%) origin was pyogenic. All cases of tbc spondylitis (except one drug resistant tbc form) were with previously proved tbc diagnosis of different localisation. Radiological findings for the tbc cases were more than two-vertebra involvement and deformation of vertebral column axis. Pyogenic spondylodiscitis (33 cases) were derived from or after - 1. lumbal discectomies (7 cases), 2. operation on retroperitoneal cavity (6 cases) including 3 cases after prothesation of abdominal aorta, 3. closed spine trauma (4 cases), 4. hematogenic dissemination of pyogenic infection from different localisation - kidney, lung, sinuses (8 cases). In 8 cases we did not estimate potential cause of spondylodiscitis. Conclusion: A definite diagnosis of spondylodiscitis was established by means of biopsy, histological evidence and bacterial culture. There are not specific radiological findings to differentiate tbc spondylodiscitis from pyogenic spondylodiscitis. (Full text)

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

    2016-12-01

    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.

    Weight preoccupations have been frequently reported in normal-weight subjects. Subthreshold anorexia nervosa (s-AN, all DSM IV TR criteria except amenorrhea or underweight) is a form of eating disorder not otherwise specified that has received scarce scientific attention. Under a case-control design we compared the general characteristics, body composition, and psychopathological features of normal-weight patients with s-AN with those of BMI- and sex-matched controls. Participants in this pilot study included 9 normal-weight women who met the DSM IV TR criteria for s-AN and 18 BMI-matched normal-weight controls. The general characteristics of the study participants were collected by questionnaire. Body composition was measured by bioelectrical impedance. Behavioral and psychological measures included the standardized symptom checklist (SCL-90-R) and the eating disorder inventory (EDI-2). There were no differences in age, education, employment status, marital status, and history of previous slimming treatment in the two study groups. In addition, anthropometric measures and body composition of s-AN patients and BMI-matched normal weight controls were not significantly different. In the s-AN subgroup, we found a significant relationship between waist circumference and the SCL-90-R obsessivity-compulsivity scale (n=9, r=-0.69, pstudy cohort. These pilot results suggest that psychopathological criteria (particularly related to the obsessivity-compulsivity dimension) may be more useful than anthropometric measures for screening of s-AN in normal-weight women.

    Operative neurosurgery has recently entered an exciting era of image guided surgery or neuronavigation and application of this novel technology is beginning to have a significant impact in many ways in a variety of intracranial procedures. In order to fully assess the advantages of image guided techniques over conventional planning and surgery in selected cases, detailed prospective evaluation has been carried out during the advanced development of an optically tracked neuronavigation system. Over a 2-year period, 300 operative neurosurgical procedures have been performed with the assistance of interactive image guidance, as well as the development of new software applications and hardware tools. A broad range of intracranial neurosurgical procedures were seen to benefit from image guidance, including 163 craniotomies, 53 interactive stereotactic biopsies, 7 tracked neuroendoscopies and 37 complex skull base procedures. The most common pathological diagnoses were cerebral glioma in 98 cases, meningioma in 64 and metastasis in 23. Detailed analysis of a battery of postoperative questions revealed benefits in operative planning, appreciation of anatomy, lesion location, safety of surgery and greatly enhanced surgical confidence. The authors believe that image guided surgical technology, with new developments such as those described, has a significant role to play in contemporary neurosurgery and its widespread adoption in practice will be realised in the near future.

    Petta, Lorene M

    2017-06-01

    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.

    2010-10-01

    To compare the clinical efficacy of grade III, IV supination-eversion fractures-dislocations of ankle joint between manipulative treatment and operative treatment. From September 2007 to December 2008, the clinical data of 60 patients with grade III, IV supination-eversion fractures-dislocations of ankle joint were retrospectively analyzed. There were 32 males and 28 females, ranging in age from 18 to 70 years with an average age of 38.17 years. All patients were respectively treated with manipulative treatment (conservative group, 30 cases) and operative treatment (operative group, 30 cases). The joint function was compared with Mazur standard; the reduction and shifting of fractures were observed with X-ray; the hospitalization day and the therapeutic cost were compared between two groups. All patients were followed up with an average of 15.27 months (ranged, 6 to 25 months). In conservative group, 16 cases got excellent result in joint function, 10 good, 3 fair, 1 poor; in operative group, 20 cases got excellent result, 8 good, 2 fair, 0 poor. In conservative group in the X-ray showed 25 cases obtained excellent and good reduction, 4 fair, 1 poor; and in operative group in the X-ray showed 28 cases obtained excellent and good reduction, 2 fair, 0 poor. There was no significant difference at the joint function and X-ray film after treatment between two groups (P > 0.05). The hospital day was respectively (7.87 +/- 3.34), (17.37 +/- 4.64) d in conservative group and operative group; and the therapeutic cost was respectively (2 506.67 +/- 649.10), (11 473.33 +/- 1 564.90) yuan. There was significant difference at hospital day and therapeutic cost between two groups (P fractures and dislocations of ankle joint. However, conservative treatment has advantage of high safety factor, low therapeutic cost, can reduce medical costs for patients.

    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.

    Suicide rate among rural elderly is the highest among all age groups in China, yet little is known about the suicide risks in this rapidly growing vulnerable population. This matched case-control psychological autopsy study was conducted during June 2014 to September 2015. Consecutive samples of suicides aged 60 or above were identified in three provinces (Shandong, Hunan, and Guangxi) in China. Living comparisons were 1:1 matched with the suicides in age (±3 years old), gender, and living location. Risk factors included demographic characteristics, being left-behind, mental disorder, depressive symptoms, stressful life events, and social support. A total of 242 suicides and 242 comparisons were enrolled: 135 (55.8%) were male, mean (s.d.) age was 74 (8) years. The most frequently used suicide means were pesticides (125, 51.7%) and hanging (95, 39.3%). Independent risks of suicide included unstable marital status [odds ratio (OR) 4.19, 95% confidence interval (CI) 1.61-10.92], unemployed (compared with employed, OR 4.43, 95% CI 1.09-17.95), depressive symptoms (OR 1.34, 95% CI 1.21-1.48), and mental disorder (OR 6.28, 95% CI 1.75-22.54). Structural equation model indicated that the association between being left-behind and suicide was mediated by mental disorder, depressive symptoms, stressful life events, and social support. Unstable marital status, unemployed, depressive symptoms, and mental disorder are independent risk factors for suicide in rural elderly. Being left-behind can elevate the suicide risk through increasing life stresses, depressive symptoms, mental disorder, and decreasing social support. Elderly suicide may be prevented by restricting pesticides, training rural physicians, treating mental disorders, mitigating life stress, and enhancing social connection.

    Surgery is one of the key functions in hospitals; it generates significant revenue and admissions to hospitals. In this paper we address the decision of choosing a case-mix for a surgery department. The objective of this study is to generate an optimal case-mix plan of surgery patients with uncertain surgery operations, which includes uncertainty in surgery durations, length of stay, surgery demand and the availability of nurses. In order to obtain an optimal case-mix plan, a stochastic optimization model is proposed and the sample average approximation method is applied. The proposed model is used to determine the number of surgery cases to be weekly served, the amount of operating rooms' time dedicated to each specialty and the number of ward beds dedicated to each specialty. The optimal case-mix selection criterion is based upon a weighted score taking into account both the waiting list and the historical demand of each patient category. The score aims to maximizing the service level of the operating rooms by increasing the total number of surgery cases that could be served. A computational experiment is presented to demonstrate the performance of the proposed method. The results show that the stochastic model solution outperforms the expected value problem solution. Additional analysis is conducted to study the effect of varying the number of ORs and nurses capacity on the overall ORs' performance.

    In line with advances in diagnostic methods and expectation of a decrease in the number of negative laparotomies, selective non-operative management of abdominal gunshot wounds has been increasingly used over the last three decades. We aim to detect the possibility of treatment without surgery and present our experience in selected cases referred from Syria to a hospital at the Turkish-Syrian border. Between February 2012 and June 2014, patients admitted with abdominal gunshot wounds were analyzed. Computed tomography was performed for all patients on admission. Patients who were hemodynamically stable and did not have symptoms of peritonitis at the time of presentation were included in the study. The primary outcome parameters were mortality and morbidity. Successful selective non-operative management (Group 1) and unsuccessful selective non-operative management (Group 2) groups were compared in terms of complications, blood transfusion, injury site, injury severity score (ISS), and hospital stay. Of 158 truncal injury patients, 18 were considered feasible for selective non-operative management. Of these, 14 (78%) patients were treated without surgery. Other Four patients were operated upon progressively increasing abdominal pain and tenderness during follow-up. On diagnostic exploration, all of these cases had intestinal perforations. No mortality was observed in selective non-operative management. There was no statistically significant difference between Group 1 and Group 2, in terms of length of hospital stay (96 and 127 h, respectively). Also, there was no difference between groups in terms of blood transfusion necessity, injury site, complication rate, and injury severity score (p>0.05). Decision making on patient selection for selective non-operative management is critical to ensure favorable outcomes. It is not possible to predict the success of selective non-operative management in advance. Cautious clinical examination and close monitoring of these

    High re-tear rate is reported after rotator cuff repair in large and massive tear cases. Previously, we reported that 15% of patients after rotator cuff repair showed re-tear in MRI findings. In this study, 116 consecutive rotator cuff repaired patients who had been operated arthroscopically since 2003 were evaluated for size, torn site, fixation methods, mobility, and tendon quality. In addition, rehabilitation methods and occupation after revision were also evaluated. There were four patients who underwent re-operation. Rotator cuff repairs by revision surgery failed mechanically due to two reasons: the main factor of failure was suture material breakage in three cases and the second was tendon pulling through sutures in one case. The lack of thread strength was suggested. In addition, it is important to pull cuff stump to greater tubercle without excessive tension. Of re-operated cases, three engaging in manual labor suffered large and massive tear. In two cases, premature return to manual labor suggested cause of re-tear. (author)

    2018-04-01

    Operations capabilities have been a popular research area for many years and several frameworks have been proposed in the literature. The current frameworks do not take specific contexts into consideration, for instance a high cost environment. This research gap is of particular interest since a manufacturing relocation process has been ongoing the last decades, leading to a huge amount of manufacturing being moved from high to low cost environments. The purpose of this study is to identify critical operations capabilities in a high cost environment. The two research questions were: What are the critical operations capabilities dimensions in a high cost environment? What are the critical operations capabilities in a high cost environment? A multiple case study was conducted and three Swedish manufacturing firms were selected. The study was based on the investigation of an existing framework of operations capabilities. The main dimensions of operations capabilities included in the framework were: cost, quality, delivery, flexibility, service, innovation and environment. Each of the dimensions included two or more operations capabilities. The findings confirmed the validity of the framework and its usefulness in a high cost environment and a new operations capability was revealed (employee flexibility).

  8. Virtual control desk for operators training: a case study for a nuclear power plant simulator

    International Nuclear Information System (INIS)

    Aghina, Mauricio Alves da Cunha e

    2009-03-01

    Nuclear Power Plant (NPP) is a facility for electrical energy generation. Because of its high degree of complexity and very rigid norms of security it is extremely necessary that operators are very well trained for the NPP operation. A mistaken operation by a human operator may cause a shutdown of the NPP, incurring in a huge economical damage for the owner and for the population in the case of a electric net black out. To reduce the possibility of a mistaken operation, the NPP usually have a full scope simulator of the plant's control room, which is the physical copy of the original control room. The control of this simulator is a computer program that can generate the equal functioning of the normal one or some scenarios of accidents to train the operators in many abnormal conditions of the plant. A physical copy of the control room has a high cost for its construction, not only of its facilities but also for its physical components. The proposal of this work is to present a project of a virtual simulator with the modeling in 3D stereo of a control room of a given nuclear plant with the same operation functions of the original simulator. This virtual simulator will have a lower cost and serves for pretraining of operators with the intention of making them familiar to the original control room. (author)

    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.

    2017-04-01

    Full Text Available Resource and cost constraints in hospitals demand thorough planning of operating room schedules. Ideally, exact start times and durations are known in advance for each case. However, aside from the first case’s start, most factors are hard to predict. While the role of the start of the first case for optimal room utilization has been shown before, data for to-follow cases are lacking. The present study therefore aimed to analyze all elective surgery cases of a university hospital within 1 year in search of visible patterns. A total of 14,014 cases scheduled on 254 regular working days at a university hospital between September 2015 and August 2016 underwent screening. After eliminating 112 emergencies during regular working hours, 13,547 elective daytime cases were analyzed, out of which 4,346 ranked first, 3,723 second, and 5,478 third or higher in the daily schedule. Also, 36% of cases changed start times from the day before to 7:00 a.m., with half of these (52% resulting in a delay of more than 15 min. After 7:00 a.m., 87% of cases started more than 10 min off schedule, with 26% being early and 74% late. Timeliness was 15 ± 72 min (mean ± SD for first, 21 ± 84 min for second, and 25 ± 93 min for all to-follow cases, compared to preoperative day planning, and 21 ± 45, 23 ± 61, and 19 ± 74 min compared to 7:00 a.m. status. Start time deviations were also related to procedure duration, with cases of 61–90 min duration being most reliable (deviation 9.8 ± 67 min compared to 7:00 a.m., regardless of order. In consequence, cases following after 61–90 min long cases had the shortest deviations of incision time from schedule (16 ± 66 min. Taken together, start times for elective surgery cases deviate substantially from schedule, with first and second cases falling into the highest mean deviation category. Second cases had the largest deviations from scheduled times compared to

    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.

    Peavy, M.A.; Braun, J.E.

    1991-01-01

    This paper presents an overview of a waste gas treatment system designed to control emissions from thermally enhanced oil recovery wells. This case study discusses the need, design, installation and operations of the system. Oryx Energy Company (Oryx) operates approximately 940 wells in the Midway-Sunset (MWSS) field under casing vapor recovery systems. The emissions collected from well casing vent gas cotaining hydrocarbons and hydrogen sulfide that are collected and processed through casing vapor recovery skids. These skids are composed of condensers, compressors, and pumps that separate fluids from the waste gas stream. The non-condensible gas is then disposed of in incinerators that reduce the hydrocarbon and sulfur emissions into the atmosphere. Approximately 91,000 lbs/day of hydrocarbon and 10,116 lbs/day of sulfur dioxide are removed from the atmosphere from wells contained within these systems operated by Oryx. These hydrocarbons yield approximately 550 barrels of oil per day (BOPD). The system helps manage the pressure differential from the reservoir into each wellbore and contributes to improved ambient air quality in Kern County, California

    2016-08-01

    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.

  19. A survey on the technologies and cases for the cognitive models of nuclear power plant operators

    1993-04-01

    To enhance the safety and availability of nuclear power plants, it is necessary to develop the methodologies which can systematically analyze the interrelationships between plant operators and main process systems. Operator congnitive models enable to provide an explicit method to analyze how operator's congitive behavior reacts to the behavior of system changes. However, because no adequate model has been developed up to now, it is difficult to take an effective approach for the review, assessment and improvement of human factors. In this study, we have surveyed the techniques and the cases of operator model development, aiming to develop an operator's model as one of human engineering application methodologies. We have analyzed the cognitive characteristics of decision-making, which is one of the principal factors for modeling, and reviewed the methodologies and implementation thechniques used in the cases of the model development. We investigated the tendencies of the model developments by reviewing ten cases and especially CES, INTEROPS and COSIMO models which have been developed or are under development in nuclear fields. Also, we summarized the cognitive characteristics to be considered in the modeling for the purpose of modeling operator's decision-making. For modeling methodologies, we found a trend of the modeling that is software simulations based on the artificial intelligence technologies, especially focused in knowledge representation methods. Based on the results of our survey, we proposed a development approach and several urgent research subjects. We suggested the development simulation tools which can be applicable to the review, assessment and improvement of human factors, by implementing them as softwares using expert system development tools. The results of this study have been applied to our long-term project named 'The Development of Human Engineering Technologies.' (Author)

    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.

    This paper reported 12 cases with brain abscess demonstrated by CT scan. Using antibiotic management without surgical intervention, in 10 cases the curative effects were satisfactory. The paper indicated that CT scan was very useful in prompt and correct diagnosis of brain abscess and with sequential CT scan medical therapy was feasible. It is significant in treatment of brain abscess especially for the patients who have a poor general condition, have the brain abscess located in important functional area or have multiple abscesses so that the operation is difficult for them.

    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.

  8. Theorising context in psychology

    DEFF Research Database (Denmark)

    Glaveanu, Vlad Petre

    2014-01-01

    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...

    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.

    2013-11-01

    Because operating room (OR) management decisions with optimal choices are made with ubiquitous biases, decisions are improved with decision-support systems. We reviewed experimental social-psychology studies to explore what an OR leader can do when working with stakeholders lacking interest in learning the OR management science but expressing opinions about decisions, nonetheless. We considered shared information to include the rules-of-thumb (heuristics) that make intuitive sense and often seem "close enough" (e.g., staffing is planned based on the average workload). We considered unshared information to include the relevant mathematics (e.g., staffing calculations). Multiple studies have shown that group discussions focus more on shared than unshared information. Quality decisions are more likely when all group participants share knowledge (e.g., have taken a course in OR management science). Several biases in OR management are caused by humans' limited abilities to estimate tails of probability distributions in their heads. Groups are more susceptible to analogous biases than are educated individuals. Since optimal solutions are not demonstrable without groups sharing common language, only with education of most group members can a knowledgeable individual influence the group. The appropriate model of decision-making is autocratic, with information obtained from stakeholders. Although such decisions are good quality, the leaders often are disliked and the decisions considered unjust. In conclusion, leaders will find the most success if they do not bring OR management operational decisions to groups, but instead act autocratically while obtaining necessary information in 1:1 conversations. The only known route for the leader making such decisions to be considered likable and for the decisions to be considered fair is through colleagues and subordinates learning the management science.

  11. Mathematical psychology.

    2010-09-01

    Mathematical psychology is a sub-field of psychology that started in the 1950s and has continued to grow as an important contributor to formal psychological theory, especially in the cognitive areas of psychology such as learning, memory, classification, choice response time, decision making, attention, and problem solving. In addition, there are several scientific sub-areas that were originated by mathematical psychologists such as the foundations of measurement, stochastic memory models, and psychologically motivated reformulations of expected utility theory. Mathematical psychology does not include all uses of mathematics and statistics in psychology, and indeed there is a long history of such uses especially in the areas of perception and psychometrics. What is most unique about mathematical psychology is its approach to theory construction. While accepting the behaviorist dictum that the data in psychology must be observable and replicable, mathematical models are specified in terms of unobservable formal constructs that can predict detailed aspects of data across multiple experimental and natural settings. By now almost all the substantive areas of cognitive and experimental psychology have formal mathematical models and theories, and many of these are due to researchers that identify with mathematical psychology.

    2014-01-01

    Socioecological psychology investigates humans' cognitive, emotional, and behavioral adaption to physical, interpersonal, economic, and political environments. This article summarizes three types of socioecological psychology research: (a) association studies that link an aspect of social ecology (e.g., population density) with psychology (e.g., prosocial behavior), (b) process studies that clarify why there is an association between social ecology and psychology (e.g., residential mobility → anxiety → familiarity seeking), and (c) niche construction studies that illuminate how psychological states give rise to the creation and maintenance of a social ecology (e.g., familiarity seeking → dominance of national chain stores). Socioecological psychology attempts to bring the objectivist perspective to psychological science, investigating how objective social and physical environments, not just perception and construal of the environments, affect one's thinking, feeling, and behaviors, as well as how people's thinking, feeling, and behaviors give rise to social and built environments.

    2013-01-01

    The success of an aircraft mission is subject to the fulfillment of some operational requirements before and during each flight. As these requirements depend essentially on the aircraft system components and the mission profile, the effects of failures can be very severe if they are not anticipated. Hence, one should be able to assess the aircraft operational reliability with regard to its missions in order to be able to cope with failures. We address aircraft operational reliability modeling to support maintenance planning during the mission achievement. We develop a modeling approach, based on a meta-model that is used as a basis: (i) to structure the information needed to assess aircraft operational reliability and (ii) to build a stochastic model that can be tuned dynamically, in order to take into account the aircraft system operational state, a mission profile and the maintenance facilities available at the flight stop locations involved in the mission. The aim is to enable operational reliability assessment online. A case study, based on an aircraft subsystem, is considered for illustration using the Stochastic Activity Networks (SANs) formalism

  14. The discourse of "social licence to operate": case study of the Australian wind industry

    Directory of Open Access Journals (Sweden)

    Nina L. Hall

    2014-12-01

    Full Text Available Social Licence to Operate is a concept from the mining industry that reflects the ongoing acceptance or approval for a development granted by local stakeholders. It is now being applied by wind farm developers. Using the Australian wind industry as a case study, this discourse analysis examined how Social Licence to Operate is perceived and operationalised, and the key themes in this conceptual and applied discourse. Discourse analysis acknowledges that language choices are not accidental and discourse reflects power relationships. The wind industry representatives interviewed considered power over the Social Licence to Operate was shared with community stakeholders. They recognised the stakeholders' power to delay or prevent projects, but rejected the notion that every stakeholder group should have veto power. Social Licence to Operate is seen by the wind industry through a business-oriented perspective, with an emphasis on business risk, and they describe the opposition to wind farms by invoking a metaphor of "battle". The industry respondents described Social Licence to Operate as incorporating the values of trust, transparency and participation—which all contribute to creating "authentic" relationships. These findings can inform Social Licence to Operate research, engagement practices, and also encourage reflection by industry representatives on their implicit intentions for stakeholder engagement.

    2007-10-01

    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.

    Fully integrated IGCC plants consist of several units. This novel integration of various plant systems places stiff new requirements on power plant design, as prediction of operating and faulted behavior is made more difficult by many different interactions. This is especially the case for the gas turbine fuel system in an IGCC power plant, as it affects and is affected by all of the other major plant systems. (orig.)

  1. Relay chatter and operator response after a large earthquake: An improved PRA methodology with case studies

    Budnitz, R.J.; Lambert, H.E.; Hill, E.E.

    1987-08-01

    The purpose of this project has been to develop and demonstrate improvements in the PRA methodology used for analyzing earthquake-induced accidents at nuclear power reactors. Specifically, the project addresses methodological weaknesses in the PRA systems analysis used for studying post-earthquake relay chatter and for quantifying human response under high stress. An improved PRA methodology for relay-chatter analysis is developed, and its use is demonstrated through analysis of the Zion-1 and LaSalle-2 reactors as case studies. This demonstration analysis is intended to show that the methodology can be applied in actual cases, and the numerical values of core-damage frequency are not realistic. The analysis relies on SSMRP-based methodologies and data bases. For both Zion-1 and LaSalle-2, assuming that loss of offsite power (LOSP) occurs after a large earthquake and that there are no operator recovery actions, the analysis finds very many combinations (Boolean minimal cut sets) involving chatter of three or four relays and/or pressure switch contacts. The analysis finds that the number of min-cut-set combinations is so large that there is a very high likelihood (of the order of unity) that at least one combination will occur after earthquake-caused LOSP. This conclusion depends in detail on the fragility curves and response assumptions used for chatter. Core-damage frequencies are calculated, but they are probably pessimistic because assuming zero credit for operator recovery is pessimistic. The project has also developed an improved PRA methodology for quantifying operator error under high-stress conditions such as after a large earthquake. Single-operator and multiple-operator error rates are developed, and a case study involving an 8-step procedure (establishing feed-and-bleed in a PWR after an earthquake-initiated accident) is used to demonstrate the methodology

  2. Integrating solar PV (photovoltaics) in utility system operations: Analytical framework and Arizona case study

    2015-01-01

    A systematic framework is proposed to estimate the impact on operating costs due to uncertainty and variability in renewable resources. The framework quantifies the integration costs associated with sub-hourly variability and uncertainty as well as day-ahead forecasting errors in solar PV (photovoltaics) power. A case study illustrates how changes in system operations may affect these costs for a utility in the southwestern United States (Arizona Public Service Company). We conduct an extensive sensitivity analysis under different assumptions about balancing reserves, system flexibility, fuel prices, and forecasting errors. We find that high solar PV penetrations may lead to operational challenges, particularly during low-load and high solar periods. Increased system flexibility is essential for minimizing integration costs and maintaining reliability. In a set of sensitivity cases where such flexibility is provided, in part, by flexible operations of nuclear power plants, the estimated integration costs vary between $1.0 and $4.4/MWh-PV for a PV penetration level of 17%. The integration costs are primarily due to higher needs for hour-ahead balancing reserves to address the increased sub-hourly variability and uncertainty in the PV resource. - Highlights: • We propose an analytical framework to estimate grid integration costs for solar PV. • Increased operating costs from variability and uncertainty in solar PV are computed. • A case study of a utility in Arizona is conducted. • Grid integration costs are found in the $1.0–4.4/MWh range for a 17% PV penetration. • Increased system flexibility is essential for minimizing grid integration costs

    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.

    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

    Egypt is one of the countries planning to introduce a NPP into its electrical power system. Although the Egyptian power system has sufficient capacity to integrate any commercially available nuclear unit as the total installed capacity of the power system is more than 32GWe, which is more than 10 times capacity of any nuclear unit in the range of 1000 to 1700MWe, the system is vulnerable to extreme voltage variations, especially voltage degradation during peak load conditions. These conditions can lead to voltage collapse if a counter measure, usually load shedding, is not taken in a proper time. Hence, it is necessary to analyze the effect of such conditions on the safe and economic operation of the NPP. In this paper we analyzed the effects of grid voltage degradation on the safe and economic operation of the Advanced Power Reactor (APR1400) to determine any adverse effects on the plant auxiliary loads while operating in the Egyptian power system. In this paper the effects of grid voltage degradation on the safe and economic operation of APR1400 were investigated taking into account, generator operating limits, plant safety requirements, operation modes and loading categories in order to determine any adverse effect on the plant auxiliary loads while operating in the Egyptian power system. The results of the load flow and motor starting analysis demonstrated that during normal operation the automatic voltage regulator and transformers OLTCs can mitigate the effect of grid voltage degradation without any detrimental effect on the plant auxiliary loads. During the highly unlikely LOCA condition if the grid voltage degraded below 95%, the degraded voltage relays at Class 1E 4.16 kV buses will trip the supply and load breakers and reconnect the required safety loads to the EDG after 4 minutes time delay. During this period the safety loads required for LOCA can be started and accelerated to their rated speed safely even in the worst case of expected degraded voltage

    2012-12-01

    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.

    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.

    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.

    The aim of the study was that to evaluate the post-operative pain in case of ano-rectal diseases wether treated by ketorolac, or buprenorphine or tramadol. The intensity of post-operative pain was evaluated in 60 patients with hemorrhoidal diseases, fistulae, abscesses and anal neoplasms, divided into three homogenous groups and treated with intramuscular ketorolac (Group I), transdermal buprenorphine (Group II) and tramadol in elastomeric pump (Group III). The average index of the visual analogue scale, as mean to evaluate the intensity of the post-operative pain, was 1,85 in the first group, 1,20 in the second one and 1,40 in the third group. In patients treated with transdermal buprenorphine or with tramadol in elastomeric pump there has been a more quick psycho-physical recovery than in those treated with ketorolac; the management of elastomeric pump represents however for patients cause of concern while the transdermal system is a kind of rational and comfortable way of treatment of the pain, with the advantage of being non-invasive. Better compliance and lower operating costs have given the preference to the use of transdermal buprenorphine for the treatment of diseases of the post-operative pain in the diseases of the anal canal.

    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.

    Background. Retrorectal cysts (RC) are unusual lesions. Publications on RC are very rare and describe a few cases at most. Methods. Authors describe five patients with RC. The diagnostics of RC was based on the medical history of the patients and the basic diagnostic investigation was trans rectal ultrasonography. An operation to remove the cysts from perineal access was the treatment administered in these cases. Results. In three cases the histopathological examination showed cystis epidermalis. In another case a cyst epithelialized with ciliated epithelium was found. In the last case bone tissue, fatty tissue and fibrous tissue were depicted, all in the state of chronic inflammation. Conclusions. Per rectum digital exam is the basic examination decisive in making the diagnosis. TRUS should be employed as the diagnostic investigation in order to estimate precisely the size of a cyst and its proportion to the rectum wall. Retrorectal cystectomy in perineal access is an effective method of treatment of this disease. This article, likewise other research works, describes a small group of patients, therefore, its conclusions should be treated as preliminary ones. (author)

    2016-06-01

    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.

    Highlights: • RAMI (Reliability, Availability, Maintainability and Inspectability) assessment of secondary heat transfer loop for a DEMO nuclear fusion plant. • Definition of a fault tree for a nuclear steam turbine operated in pulsed mode. • Turbine failure rate models update by mean of a Bayesian network reflecting the fault tree analysis in the considered scenario. • Sensitivity analysis on system availability performance. - Abstract: Availability will play an important role in the Demonstration Power Plant (DEMO) success from an economic and safety perspective. Availability performance is commonly assessed by Reliability Availability Maintainability Inspectability (RAMI) analysis, strongly relying on the accurate definition of system components failure modes (FM) and failure rates (FR). Little component experience is available in fusion application, therefore requiring the adaptation of literature FR to fusion plant operating conditions, which may differ in several aspects. As a possible solution to this problem, a new methodology to extrapolate/estimate components failure rate under different operating conditions is presented. The DEMO Balance of Plant nuclear steam turbine component operated in pulse mode is considered as study case. The methodology moves from the definition of a fault tree taking into account failure modes possibly enhanced by pulsed operation. The fault tree is then translated into a Bayesian network. A statistical model for the turbine system failure rate in terms of subcomponents’ FR is hence obtained, allowing for sensitivity analyses on the structured mixture of literature and unknown FR data for which plausible value intervals are investigated to assess their impact on the whole turbine system FR. Finally, the impact of resulting turbine system FR on plant availability is assessed exploiting a Reliability Block Diagram (RBD) model for a typical secondary cooling system implementing a Rankine cycle.

    2016-01-01

    Grid operators increasingly have to collaborate with other actors in order to realize smart grid innovations. For routine maintenance, grid operators typically acquire technologies in one-off transactions, but the innovative nature of smart grid projects may require more collaborate relationships. This paper studies how a transactional versus relational approach to governing smart grid innovation projects affects incentives for other actors to collaborate. We analyse 34 cases of smart grid innovation projects based on extensive archival data as well as interviews. We find that projects relying on relational governance are more likely to provide incentives for collaboration. Especially non-financial incentives such as reputational benefits and shared intellectual property rights are more likely to be found in projects relying on relational governance. Policy makers that wish to stimulate smart grid innovation projects should consider stimulating long-term relationships between grid operators and third parties, because such relationships are more likely to produce incentives for collaboration. - Highlights: • Smart grids require collaboration between grid operators and other actors. • We contrast transactional and relational governance of smart grid projects. • Long-term relations produce more incentives for smart grid collaboration. • Non-financial incentives are more important in long-term relations. • Policy makers should stimulate long-term relations to stimulate smart grids.

    Diabetes insipidus (DI) is characterized by excessive urination and thirst. This disease results from inadequate output of antidiuretic hormone (ADH) from the pituitary gland or the absence of the normal response to ADH in the kidney. We present a case of transient central DI in a patient who underwent a cardiopulmonary bypass (CPB) for coronary artery bypass grafting (CABG). A 44-yr-old male underwent a CABG operation. An hour after the operation, the patient developed polyuria and was diagnosed with central DI. The patient responded to desmopressin and completely recovered five days after surgery. It is probable that transient cerebral ischemia resulted in the dysfunction of osmotic receptors in the hypothalamus or hypothalamus-pituitary axis during CPB. It is also possible that cardiac standstill altered the left atrial non-osmotic receptor function and suppressed ADH release. Therefore, we suggest that central DI is a possible cause of polyuria after CPB.

    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.

    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.

  5. A formulation to analyze system-of-systems problems: A case study of airport metroplex operations

    Science.gov (United States)

    Ayyalasomayajula, Sricharan Kishore

    A system-of-systems (SoS) can be described as a collection of multiple, heterogeneous, distributed, independent components interacting to achieve a range of objectives. A generic formulation was developed to model component interactions in an SoS to understand their influence on overall SoS performance. The formulation employs a lexicon to aggregate components into hierarchical interaction networks and understand how their topological properties affect the performance of the aggregations. Overall SoS performance is evaluated by monitoring the changes in stakeholder profitability due to changes in component interactions. The formulation was applied to a case study in air transportation focusing on operations at airport metroplexes. Metroplexes are geographical regions with two or more airports in close proximity to one another. The case study explored how metroplex airports interact with one another, what dependencies drive these interactions, and how these dependencies affect metroplex throughput and capacity. Metrics were developed to quantify runway dependencies at a metroplex and were correlated with its throughput and capacity. Operations at the New York/New Jersey metroplex (NYNJ) airports were simulated to explore the feasibility of operating very large aircraft (VLA), such as the Airbus A380, as a delay-mitigation strategy at these airports. The proposed formulation was employed to analyze the impact of this strategy on different stakeholders in the national air transportation system (ATS), such as airlines and airports. The analysis results and their implications were used to compare the pros and cons of operating VLAs at NYNJ from the perspectives of airline profitability, and flight delays at NYNJ and across the ATS.

    Full Text Available The concept of leadership is extremely complex and very often, there is a confusion between leadership and management. Although people are using these words interchangeably, they play very different, but still essential, roles. This paper aims to present a case study regarding an implementation project in banking back-office activities, in order to prove the importance of managing correct the back-office resources, but in the same time the need for a vision that would lead the people toward the scope of a project. The paper describes the existence of a relationship between leadership and operational excellence, also.

    Full Text Available Intranasal meningoencephaloceles have historically been managed by neurosurgeons, although their main clinical manifestations are rhinological. Recent advances in endoscopic skull base surgery has significantly improved the treatment of these lesions and consequently diminished appreciable surgical morbidity. We report an ethmoidal meningoencephalocele case operated on by endonasal endoscopic approach for removal of the lesion and reconstructing the associated skull base. From this experience, we conclude that removal of the lesion and watertight closure of the skull base irrespective of the size of the mass and anterior skull base defect are the operation’s most important aspects.

    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.

    1994-01-01

    Paradigmatic or psychological behaviorism (PB), in a four-decade history of development, has been shaped by its goal, the establishment of a behaviorism that can also serve as the approach in psychology (Watson's original goal). In the process, PB has become a new generation of behaviorism with abundant heuristic avenues for development in theory, philosophy, methodology, and research. Psychology has resources, purview and problem areas, and nascent developments of many kinds, gathered in chaotic diversity, needing unification (and other things) that cognitivism cannot provide. Behaviorism can, within PB's multilevel framework for connecting and advancing both psychology and behaviorism. PMID:22478175

  14. Worst-case prediction of normal operating containment temperatures for environmentally qualified equipment

    International Nuclear Information System (INIS)

    Krasnopoler, M.J.; Sundergill, J.E.

    1991-01-01

    Due to issues raised in NRC Information Notice No. 87-65, a southern US nuclear plant was concerned about thermal aging of environmentally qualified (EQ) equipment located in areas of elevated containment temperatures. A method to predict the worst-case monthly temperatures at various zones in the containment and calculate the qualified life using this monthly temperature was developed. Temperatures were predicted for twenty locations inside the containment. Concern about the qualified life of EQ equipment resulted from normal operating temperatures above 120F in several areas of the containment, especially during the summer. At a few locations, the temperature exceeded 140F. Also, NRC Information Notice No. 89-30 reported high containment temperatures at three other nuclear power plants. The predicted temperatures were based on a one-year containment temperature monitoring program. The monitors included permanent temperature monitors required by the Technical Specifications and temporary monitors installed specifically for this program. The temporary monitors were installed near EQ equipment in the expected worst-case areas based on design and operating experience. A semi-empirical model that combined physical and statistical models was developed. The physical model was an overall energy balance for the containment. The statistical model consists of several linear regressions that conservatively relate the monitor temperatures to the bulk containment temperature. The resulting semi-empirical model predicts the worst-case monthly service temperatures at the location of each of the containment temperature monitors. The monthly temperatures are the maximum expected because they are based on the historically worst-case atmospheric data

  15. A case method for Sales and Operations Planning: a learning experience from Germany

    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.

  16. Open-Source as a strategy for operational software - the case of Enki

    Science.gov (United States)

    Kolberg, Sjur; Bruland, Oddbjørn

    2014-05-01

    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

  17. Diet and psychological health.

    Science.gov (United States)

    Miller, M

    1996-09-01

    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.

    2014-05-01

    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.

    2007-01-01

    Large field of view gamma cameras are widely used to perform lymphoscintigraphy in the sentinel lymph nodes (SLN) procedure in case of breast cancer. 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...

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

    Directory of Open Access Journals (Sweden)

    2017-03-01

    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

    Full Text Available Abstract A few cases of fire in the operating room are reported in the literature. The factors that may initiate these fires are many and include alcohol based surgical prep solutions, electrosurgical equipment, flammable drapes etc. We are reporting a case of fire in the operating room while operating on a patient with burst fracture C6 vertebra with quadriplegia. The cause of the fire was due to incomplete drying of the covering drapes with an alcohol based surgical prep solution. This paper discusses potential preventive measures to minimize the incidence of fire in the operating room.

    A case of encapsulated subdural empyema was reported. This 1.5-year-old boy was admitted with the increasing confusion and convulsion. Eight months prior to admission, he had craniotomy for traumatic acute epidural hematoma on the left side. Following a coagulation of the middle meningeal artery which was the bleeding source, the dura was opened but no cortical damage was noted at that time. The computed tomographic (CT) scan on admission revealed a large subdural collection with a thin enhancing rim on the left side. Emergency craniotomy revealed a collection of subdural pus, which was irrigated and a catheter was put for continuous drainage. Postoperatively, the patient did well, however, following removal of the catheter, three weeks after the first operation, the subdural empyema was reexpanded with a very thick enhancing rim on CT scan. Ultrasonography also clearly demonstrated the formation of the thick membranes. The large craniotomy was performed and empyema with the outer and inner memberanes of 8mm thick was totally excised. Post-operative CT scan did not show any enhancing rim, indicating that enchancement was caused by newly formed vessels within the membranes per se. This findings are totally different from those observed in the brain abscess in which ring enhancement on CT continues months to years following so-called extracapsular excision of abscess. In the brain abscess, surrounding glial tissue with plenty neovascularization is left intact, even after the operation. (author).

    Arteriosclerosis is a disease effecting large elastic, elastic muscular and large muscular arteries. The primary pathological changes are found inside the arteries. Salient feature is atherosclerotic plaque. The main purpose of this paper is to determine whether early kinesitherapy with verticalization and mobilization can give better rehabilitation results with patients after lower extremities operation, in comparison to patients which were not mobilized early in this stage. In this paper we have analyzed two groups of 40 patients that were operatively treated for circulation obstruction to lower extremities. The first, tested group was treated with early kinesiotherapy with early verticalization and mobilization. The second, controlled group was treated with kinesitherapy in bed. All the patients were analyzed according to their gender, age, primary diagnosis, postoperative complications, as well as capabilities for everyday activities. For the evaluation of the everyday life activities we used the Barthel index at hospital admission and discharge. Both groups of patients were equable in gender and age. The most common age group within the tested groups was between 61-70 for males and 51-60 for woman.The most common type of obstruction in both groups was occlusion of femoral artery. The complications which occurred among the tested patients were thrombosis, ileus and contracture in 7.5% of cases, while 85% of patients did not have any complications. Within the controlled group, decubitus occurred in 7.5% of cases, as well as gangrene and ileus. Ulcus occurred in 5% of patients, thrombosis in 10%, and contracture in 4% of cases. 40% of patients in this group were without complications. Based on the results stated above we can conclude that early kinesitherapy with verticalization and mobilization of patients in postoperative phase after the treatment of lower extremities obstruction, have shown much better results in comparison to the patients which were only

    Objective: To compare the pre-operative central corneal thickness (CCT) in paediatric cataract patients with reference to normal control group. Study Design: A case control study. Place and Duration of Study: Paediatric Ophthalmology Clinic of Al-Shifa Trust Eye Hospital (ASTEH), Rawalpindi, from November 2009 to May 2010. Methodology: The study included 116 subjects with equal number of cases and controls. Demographic profile of all the subjects was noted followed by history and detailed ophthalmic examination. CCT was measured using an ultrasonic pachymeter (model Pac Scan 300). The mean of three measurements from the central cornea were recorded in microns. Results were analyzed using SPSS version 17.0. Results: Mean CCT values of the cases was 566.83 +- 37.646 microns while the control group had a mean CCT of 535.81 +- 24.466 microns. Difference between the CCT values of the two groups was highly significant (p < 0.001). Conclusion: Eyes with congenital cataracts have greater CCT values as compared to normal paediatric population. This factor must be kept in mind while interpreting intra-ocular pressure in such patients. (author)

    Full Text Available Bernard-Soulier syndrome belongs to congenital thrombocytopathic platelet disorders. There is a change of the structure of the glycoprotein in platelet membrane, causing the impair of platelet adherence on the blood vessel wall. This syndrome is clinically manifested by spontaneous bleeding in the skin and mucosa. The prognosis is usually good with an adequate support, but serious bleeding episodes occur during menstruation, trauma or surgery intervention. Treatment of bleeding or prophylaxis during surgical intervention is usually based upon platelet transfusion and the use of antifibrinolitic drugs. The object of case report is the significance of the right and an adequate preparation for the operational treatment: Mrs 42 year old, with diagnosis: Bernard-Soulier thrombocytopathia. Iron deficiency anemia. Status post operationem cystis ovarii sinistri. Admitted to the Clinic of gynaecology and obstetrics 'Narodni front' for operative treatment. The menstrual cycle is on 28 days, duration 7 days. From juvenile period there were reports of episodes of bleeding with thrombocytopathia. In prepartal period transfused with few doses of platelet. All dental interventions followed with bleeding, done with 6 doses of platelet concentrate. The history of operation of a cyst with a diagnosis: Cysta ovarii lateralis dextri torquata in 2005. The operation followed with pre-operative use of 15 doses of platelet concentrate, 2 units of fresh frosen plasm and 3 units of deplasmatic erythrocytes. There was a report of adverse reaction due to plasm transfusion and erythrocytes as a hypersensitive reaction, but during operation, there was no bigger post-operative bleeding. In following 2 years, the patient was hospitalized few times because of seriuos menometrorrhagia, and conservativly treated with iron preparations, with a difficult tolerating. Anamnesis: allergy to preparation of salicylate, ranitidin, diclofenac and tranexamic acid. In last hospitalization

    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.

    Natural orifice transluminal endoscopic surgery (NOTES) is a novel technique that aims at reducing or abolishing skin incisions and potentially also postoperative pain. The purpose of this study was to analyse operative and long-term results of a series of hybrid transvaginal cholecystectomy. Between July 2007 and May 2009, transvaginal NOTES cholecystectomy for symptomatic cholelithiasis was performed by a hybrid technique in 18 women (mean age 54 years), including four women with a body mass index >30 kg/m(2). Dissection was conducted in the first four cases by a round-tip unipolar electrode (UE) introduced through the operative channel of the endoscope coming from the vagina and in the last 14 cases by a ultrasonic scalpel (US) introduced through a 5-mm abdominal port. The short-term outcomes and the long-term results of the two methods were compared. The transvaginal approach entailed no intraoperative complication and no conversion. The overall mean duration of procedures was 75 min (range 40-190). In the first four cases (UE), the operating time was 148 min (range 140-190), whilst in the last 14 (US), it was considerably shorter, 53 min (range 40-60, p < 0.01). We experienced one biliary leak in the UE group, whilst morbidity with US was nil (p < 0.005). The biliary leak healed in 7 days with nasobiliary drainage. No other complications were encountered in either group. The mean follow-up was 12 months (range 1-22), and none of the patients has complained of dyspareunia or other colpotomy-related complications so far. Until specifically designed endoscopic tools are available for NOTES, the hybrid technique with US dissection conducted through a 5-mm port should be preferred in transvaginal cholecystectomy in order to shorten the duration of surgery and make this approach effective, safe and reproducible. After a mean follow-up of 1 year, none of our patients has complained of any problem related to transvaginal approach.

    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.

  16. Mass media constructions of 'socio-psychological epidemics' in sub-Saharan Africa: The case of genital shrinking in 11 countries.

    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.

    Two patients with Björk Shiley mitral valve replacement had migration and embolization of the occluding disc. One patient suffered migration of the disc a few hours after surgery and the other had a strut fracture with disc translocation six years after the initial operation. Clinical signs in both cases were pulmonary edema, cardiogenic shock, and absence of prosthetic sounds. Both patients were reoperated on an emergency basis, recovering after a complicated postoperative course. They are on functional Class I, 8 and 1 years later, respectively, with their dislodged discs still in the abdominal aorta. The only hope for survival in these patients is emergency reoperation, once the prosthetic mitral valve dysfunction is confirmed.

    System models are often touted as engineering tools that promote better understanding of systems, but these models are typically created during system design. The Ground Data System (GDS) team for the Dawn spacecraft took on a case study to see if benefits could be achieved by starting a model of a system already in operations. This paper focuses on the four steps the team undertook in modeling the Dawn GDS: defining a model structure, populating model elements, verifying that the model represented reality, and using the model to answer system-level questions and simplify day-to-day tasks. Throughout this paper the team outlines our thought processes and the system insights the model provided.

    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.

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

    Directory of Open Access Journals (Sweden)

    Milagros Sosa

    2012-06-01

    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.

    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.

    Objectives  To discuss the use of the posterior petrosal approach for the resection of a retrochiasmatic craniopharyngioma. Design  Operative video. Results  In this case video, the authors discuss the surgical management of a large craniopharyngioma, presenting with mass effect on the third ventricle and optic apparatus. A first surgical stage, through an endoscopic endonasal transtubercular approach, allowed satisfactory decompression of the optic chiasma and nerves in preparation for adjuvant therapy. However, accelerated growth of the tumor, with renewed visual deficits and mass effect on the hypothalamus and third ventricle, warranted a supplementary resection. A posterior transpetrosal 1 2 (also called "retrolabyrinthine transtentorial") was performed to obtain a better exposure of the tumor and the surrounding anatomy (floor and walls of the third ventricle, perforating vessels, optic nerves, etc.) 3 . Nuances of technique and surgical pearls related to the posterior transpetrosal are discussed and illustrated in this operative video, including the posterior mobilization of the transverse-sigmoid sinuses junction, preservation of the venous anatomy during the tentorial incision, identification and preservation of the floor of the third ventricle during tumor resection, and a careful multilayer closure. Conclusion  Retrochiasmatic craniopharyngiomas are difficult to reach tumors that often require skull base approaches, either endoscopic endonasal or transcranial. The posterior transpetrosal approach is an important part of the surgical armamentarium to safely resect these complex tumors. The link to the video can be found at: https://youtu.be/2MyGLJ_v1kI .

    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.

  7. De-regulated electric power markets and operating nuclear power plants: the case of British energy

    Hewlett, James G.

    2005-01-01

    One issue addressed in almost all electric power restructuring/de-regulation plans in both the United States (US) and the United Kingdom (UK) was the recovery of operating nuclear power plant's spent fuel disposal costs and the expenditures to decommission the units when they are retired. Prior to restructuring, in theory at least, in both countries, electricity consumers were paying for the back end costs from operating nuclear power plants. Moreover, in virtually all cases in the US, states included special provisions to insure that consumers would continue to do so after power markets were de-regulated. When power markets in the UK were initially restructured/de-regulated and nuclear power privatized, the shareholders of British Energy (BE) were initially responsible for these costs. However, after electricity prices fell and BE collapsed, the British government shifted many of the costs to future taxpayers, as much as a century forward. If this was not done, the book value of BE's equity would have been about -3.5 billion pounds. That is, BE's liabilities would have been about -3.5 billion pounds greater than their assets. It is difficult to see how BE could remain viable under such circumstances

    This exploratory case study examines the social, economic, and political/institutional impacts of two operating nuclear power complexes on two New England communities. This work is one of a series planned to broaden knowledge of the effects of large energy generating facilities upon the social structure of local communities. Its primary objectives are to investigate and assess social and economic impacts resulting from construction and operation of nuclear power plants and to generate hypotheses about such impacts for future testing. The study concludes that construction impacts were minor due to a dispersed commuting pattern by construction workers and that the only significant construction impact that can be identified retrospectively is construction-worker traffic. The primary impact of the nuclear power plants in both communities was the massive increase in property tax payments paid to the local communities by the utilities and the option chosen by each community to maintain the existing tax rate while using the additional revenue to significantly increase and enhance the public service delivery systems and facilities within the community. Second-order consequences of the direct, first-order economic impact were: (1) changes in community land use policies, (2) increase in salience of growth issues, and (3) alteration of both inter- and intra-community relationships. The majority of residents in both communities express favorable attitudes toward the nuclear plants, primarily because of the substantial increase in the tax base of their communities

    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)

  10. Operational Complexity of Supplier-Customer Systems Measured by Entropy—Case Studies

    Full Text Available This paper discusses a unified entropy-based approach for the quantitative measurement of operational complexity of company supplier-customer relations. Classical Shannon entropy is utilized. Beside this quantification tool, we also explore the relations between Shannon entropy and (c,d-entropy in more details. An analytic description of so called iso-quant curves is given, too. We present five case studies, albeit in an anonymous setting, describing various details of general procedures for measuring the operational complexity of supplier-customer systems. In general, we assume a problem-oriented database exists, which contains detailed records of all product forecasts, orders and deliveries both in quantity and time, scheduled and realized, too. Data processing detects important flow variations both in volumes and times, e.g., order—forecast, delivery—order, and actual production—scheduled one. The unifying quantity used for entropy computation is the time gap between actual delivery time and order issue time, which is nothing else but a lead time in inventory control models. After data consistency checks, histograms and empirical distribution functions are constructed. Finally, the entropy, information-theoretic measure of supplier-customer operational complexity, is calculated. Basic steps of the algorithm are mentioned briefly, too. Results of supplier-customer system analysis from selected Czech small and medium-sized enterprises (SMEs are presented in various computational and managerial decision making details. An enterprise is ranked as SME one, if it has at most 250 employees and its turnover does not exceed 50 million USD per year, or its balance sheet total does not exceed 43 million USD per year, alternatively.

    Polygamy is defined as a marriage in which a spouse of either gender has more than one mate at the same time. Polygamy is considered a valid form of marriage in many countries and communities around the globe. The purpose of this study is to examine the psychological symptoms, family function, marital satisfaction, life satisfaction and the degree of agreement with the practice of polygamy among 'senior wives' - the first wife in the polygamous marriage - and women in monogamous marriages in the West Bank, Palestine. A convenience sample of 309 women, 187 from polygamous and 122 from monogamous families, participated in this study. All women from polygamous families were senior wives. The following instruments were deployed: the McMaster Family Assessment Device (FAD), the ENRICH marital satisfaction questionnaire, the SCL-90 mental health symptoms checklist, the Rosenberg self-esteem (SE) scale, the Diener et al. (1985), a life satisfaction scale, and a basic socio-demographic scale, including the degree of agreement of the practice of polygamy. The findings revealed significant differences between senior wives in polygamous marriages and wives in monogamous marriages with regard to family functioning, marital satisfaction, self-esteem and life satisfaction. Likewise, many of the mental health symptoms were different. Particularly noteworthy were somatization, depression, hostility psychotism and the General Severity Index (a global index of distress). More women in polygamous marriages agreed with the practice of polygamy than their monogamous counterparts. Practitioners and policy makers need to be aware of the consequences of polygamy on first wives and on society as whole.

    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.

    Takotsubo cardiomyopathy (TSCM) has detrimental effects on both physical and psychological health of sufferers. However, little is known whether TSCM also affects sexual functioning in female patients. The aim of this study was to investigate psychological distress (depression and anxiety), health-related quality of life, and sexual functioning in women with TSCM and compare them with women with acute myocardial infarction and with healthy controls. A three group prospective case-control design was used. Female patients with TSCM or acute myocardial infarction, as well as healthy controls (94 in each group), were recruited across eight Iranian university hospitals. Data were collected at baseline and after six and 18 months using the Hospital Anxiety and Depression Scale, the Short Form-12, the Female Sexual Function Index and the Female Sexual Distress Scale. Multilevel logistic regression was conducted. The TSCM group showed worst sexual functioning and the highest level of anxiety and depression at baseline ( pquality of life at baseline, which was lower in both groups compared with the healthy controls ( pquality of life showed a significant change over time, especially in the TSCM group, with health-related quality of life decreasing, while anxiety and depression were increasing. Compared with the acute myocardial infarction and healthy control groups, the TSCM group showed a higher prevalence of sexual problems (odds ratios = 3.10 and 2.28, respectively) across time. Moreover, sexual functioning was found to be a mediator between anxiety and health-related quality of life in the TSCM group. Depression, anxiety, health-related quality of life, and sexual dysfunction tend to increase over time in female patients with TSCM; thus, healthcare providers should pay attention to these problems and provide appropriate treatment where necessary.

    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.

    Full Text Available The present study was conducted in Naranjo County located in the municipality of Mixco, Guatemala. The water supply source comes from two wells with a maximum flow of 25.24 and 33.44 L·s−1. The main problem with this source is the high arsenic concentration—between 0.1341 and 0.1671 mg·L−1. The aim of this study was to conduct laboratory tests, basic engineering and supervision of the construction and evaluation of an operations plant using two configurations, A (low-rate sedimentation and ceramic filter and B (high-rate sedimentation and clinoptilolite filter, to remove arsenic present in water for human use and consumption. This plant supplies water to Naranjo County in Mixco, Guatemala (5000 inhabitants. First, a laboratory Jar Test was performed to evaluate arsenic removal efficiency. And second, a conventional clarification plant was then built (design flow: 25.24 L·s−1. The best results were achieved with configuration B, with the following reagents and dosage as defined by the laboratory tests: 10 mg L−1 ferric chloride as coagulant; 1.8 mg·L−1 CH-polyfocal as flocculant and 0.4 mg L−1 MIT03 as color removal; 1 mg L−1 sodium hypochlorite as oxidant and adjusting pH to ≈7.0 with sodium hydroxide. Once the plant began operating, the efficiency of the treatment process was evaluated. The maximum elimination efficiencies were obtained 100% for turbidity (0 UTN, 89.54% (3.66 UPt-Co for color and 96.80% (0.005 mg L−1 for arsenic, values that comply with Guatemalan standards. For this case, the relation between Fe(III dosage/mg and As(V removal was 1:46.

    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.

    Highlights: • The shielding effect of WECs located around the wind farm is analysed. • The height wave reductions achieved by 15 different layouts are compared. • The increase in the accessibility to the wind turbines is quantified. • Alpha Ventus offshore wind farm is considered as baseline scenario. • High-resolution numerical modelling (SWAN) and real sea conditions are used. - Abstract: Operation and maintenance can jeopardise the financial viability of an offshore wind energy project due to the cost of downtime, repairs and, above all, the inevitable uncertainties. The variability of wave climate can impede or hinder emergency repairs when a failure occurs, and the resulting delays imply additional costs which ultimately reduce the competitiveness of offshore wind energy as an alternative to fossil fuels. Co-located wind turbines and Wave Energy Converters (WECs) are proposed in this paper as a novel solution: the reduction of the significant wave height brought about by the WECs along the periphery of the wind farm results in a milder wave climate within the farm. This reduction, also called shadow effect, enlarges weather windows for Operation and Maintenance (O and M). The objective of this paper is to investigate the increase in the accessibility time to the turbines and to optimise the layout for the co-located wind-wave farm in order to maximise this time. The investigation is carried out through a case study: Alpha Ventus, an operating offshore wind farm. To maximise the reduction of wave height in the turbine area no fewer than 15 layouts are tested using high-resolution numerical modelling, and a sensitivity analysis is conducted. The results show that, thanks to the wave energy extraction by the WECs, weather windows (access time) can increase very significantly – over 80%. This substantial effect, together with other benefits from the combination of wave and offshore wind power in a co-located farm (common electrical infrastructures

    Full Text Available Anorexia nervosa (AN is an eating disorder, which is characterized by the avoidance of eating in a way that threatens the physical integrity of an individual, and trying to lose weight. It is known that the risk of mortality is high in AN. Death occurs as a results of medical complications and/or suicide. On the other hand, the exact time point of mortality becoming a risk during the progression of the disease progression is not defined. Certain predictors have been defined for mortality in AN. In this study, our aim was to present a case of a 15-year old female patient, who had died due to medical complications related to AN. J Clin Exp Invest 2015; 6 (4: 393-395

    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

    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.

    Full Text Available We present a rare case of a spontaneous perforation of the bladder in a female patient who underwent thoracic operation. A 45 year-old female patient with no other comorbidities was admitted to the department of thoracic and abdominal surgery of University hospital “Sveti Georgi” with clinical, laboratory and image findings of right lung abscess. A right thoracotomy was performed, a large lung abscess was found and upper right bilobectomy was performed. On the day of her discharge she complained of a sudden abdominal pain, ballooning of the abdomen, nausea and vomiting. The ultrasonography showed a free fluid in the peritoneal cavity. An urgent laparotomy was performed, a perforation of the bladder was found, resection of the necrotic part of the wall and two layer suture of the bladder were performed by urologist. Postoperatively, we had multiple complications. Tuberculosis was considered as one of the most likely diagnosis but was subsequently rejected. The patient was discharged after 70 days of hospital stay in a good health condition.

    To report complications and owner satisfaction for dogs and cats following partial caudectomy. Medical records of dogs and cats (n = 22) that underwent partial caudectomy between 2008 and 2013 were retrospectively reviewed. Signalment, reason for amputation, level of amputation, and complications were recorded. Owners were contacted via telephone to obtain follow-up data. The most common reason for partial caudectomy was tail wounds (16 of 22; 72 · 7%). Complications were typically minor incisional crusting (4 of 20; 20%). Major complications (3 of 20; 15%) included prolonged healing after partial incisional dehiscence, continued self-trauma requiring revision surgery, and severe inflammation with ulceration requiring revision surgery. The majority of owners surveyed (10 of 12; 83 · 3%) were satisfied with the post-operative outcome and would recommend this procedure if warranted. Partial caudectomy is well tolerated in both dogs and cats with no loss of function. Pet owners did not perceive any behavioural changes following partial caudectomy. However, in cases of continued self-mutilation and/or incisional dehiscence, revision procedures may be required. © 2014 British Small Animal Veterinary Association.

    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.

    Operators and their submatrix elements are studied in the framework of the electric multipole transitions of complex atoms with account of relativistic corrections of the order of the square of the fine structure constant. The analysis is performed by means of irreducible tensor operators and genealogical coefficients. It has been assumed that angular momenta of individual shells are coupled with each other according to ls, lk, jk and jj coupling. Formulas are given for the operator which causes the relativistic corrections for the single-electron multipole transition and for its submatrix element in the case of configurations with two unfilled shells. A possibility is discussed of using the formulas suggested for calculation. As follows from analysis, the relativistic correction operators even with the pure ls coupling allow intercombination transitions with ΔS equals +-1. The expressions obtained may turn out to be useful for performing calculations in the case of the intermediate type of coupling

    In Japan, indications for opioid analgesics, once exclusively used as pain killers for patients suffering from malignant cancer, have been expanded for a wide range of pain. Herein we report a patient with opioid-induced delirium associated with the administration of buprenorphine patches that was well below the indicated therapeutic range limit. An 82-year-old woman was referred to us from an orthopaedic practitioner for uncontrollable behavioural problems apparently caused by the beginning of dementia; the patient had gradually developed disorientation, visual hallucinations, and delusions. Laboratory and imaging findings excluded common causes of delirium including Alzheimer's disease and diffuse Lewy body disease. Detailed questioning revealed that the patient's confused state appeared following a buprenorphine patch dose increase and subsequently disappeared after administration was stopped. Delirium has not been reported as a side-effect in clinical trials of buprenorphine patches. However, our findings in this case show that even topical opioids can precipitate the development of a delirious state in elderly patients. © 2013 The Authors.

    In the present paper, one presents an approach to hazard identification and risks quantification concerning the use of retrievable BHA, of a casing drilling system, in 12 1/4 phase of an onshore well. The adopted approach can be subdivided as: execution of a hazard and operability study; prioritization of critical deviance; modeling of critical deviance by mean of event sequence diagram, fault tree and Bayesian network; modeling and simulation of a dynamic decision tree and experts' opinion analysis. As results, one has obtained: the time distribution to achieve the different ends modeled in the decision tree, i.e., sidetrack, or operation canceling, or success; the probabilities to achieve each modeled end and all recommendation to improve the success probability. The approach proved to be efficient in order that it presents significant results to support the decisions involving the casing drilling operations. (author)

    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).

    2018-03-01

    Nowadays, for a number of reasons, many open pit mines are considering a transition from Open Pit (OP) to Underground (UG) to remain competitive. In OP-UG transition, UG operation is operated simultaneously with the OP operation for a certain period of time. Guidelines for the simultaneous operation of OP and UG are very difficult to establish, as there are very few case studies available. Yet, because of the OP-UG interactions; the operation has a higher safety, technical and management requirements than the OP or UG methods when considered separately. In Vietnam, Cao Son is one of many OP mines, which decided to change the operational system from OP to UG. Simultaneous operation started in 2015 and will be conducted until 2030 when the OP mine Cao Son ends its mining activities. In this paper, selected geomechanical considerations of the simultaneous operation are presented. A number of numerical modelling calculations using finitedifference software with code FLAC were carried out for calibration process, slope stability analysis and the OP-UG interaction analysis for the Cao Son - Khe Cham II-IV mine. Based on the results obtained from numerical modelling, the geomechanical assessments of simultaneous operation Cao Son - Khe Cham II-IV are discussed in this paper.

    In 2009, the International Union Against Tuberculosis and Lung Disease (The Union) and Médecins Sans Frontières (MSF) jointly developed a new paradigm for operational research (OR) capacity building and started a new process of appointing and supporting OR fellows in the field. This case study describes 1) the appointment of two OR fellows in The Union South-East Asia Office (USEA), New Delhi, India; 2) how this led to the development of an OR unit in that organisation; 3) achievements over the 5-year period from June 2009 to June 2014; and 4) challenges and lessons learnt. In June 2009, the first OR fellow in India was appointed on a full-time basis and the second was appointed in February 2012—both had limited previous experience in OR. From 2009 to 2014, annual research output and capacity building initiatives rose exponentially, and included 1) facilitation at 61 OR training courses/modules; 2) publication of 96 papers, several of which had a lasting impact on national policy and practice; 3) providing technical assistance in promoting OR; 4) building the capacity of medical college professionals in data management; 5) support to programme staff for disseminating their research findings; 6) reviewing 28 scientific papers for national or international peer-reviewed journals; and 7) developing 45 scientific abstracts for presentation at national and international conferences. The reasons for this success are highlighted along with ongoing challenges. This experience from India provides good evidence for promoting similar models elsewhere. PMID:26400596

  2. Visualizing feasible operating ranges within tissue engineering systems using a "windows of operation" approach: a perfusion-scaffold bioreactor case study.

    Science.gov (United States)

    McCoy, Ryan J; O'Brien, Fergal J

    2012-12-01

    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.

    This article starts out with a detailed example illustrating the utility of applying quantum probability to psychology. Then it describes several alternative mathematical methods for mapping fundamental quantum concepts (such as state preparation, measurement, state evolution) to fundamental psychological concepts (such as stimulus, response, information processing). For state preparation, we consider both pure states and densities with mixtures. For measurement, we consider projective measurements and positive operator valued measurements. The advantages and disadvantages of each method with respect to applications in psychology are discussed. (paper)

    Full Text Available Globally, transportation sector has emerged as one of the major sources of air pollution. Correspondingly, green mobility (with electric bus is gaining increasing attention as an essential step to mitigate emission concern. As such, a proper electric bus network design and fleet planning is important especially for bus operator to acquire an adequate number of electric bus, right on time, in order to operate electric bus system viably. Thus, this paper aims to examine the possibility to operate electric bus as a replacement for the conventional bus operation (with natural gas buses for the study area in Putrajaya, Malaysia. In order to determine a proper-designed electric bus operating system in terms of electric bus route, service frequency and quantity, the proposed methodology is developed with the aid of a traffic modeling software to cater various scenarios. Based on the existing (conventional traffic and transit system in Putrajaya, the developed electric bus operating model is calibrated accordingly by considering various operational concerns including battery capacity and charging facility. The resultant findings revealed that the developed electric bus operating system in Putrajaya outperforms the conventional bus operation, not only in generating a higher profit margin for the bus operator, but also satisfying the passengers in a better manner (by carrying more passengers per unit of bus with a lower energy consumption.

    2003-01-01

    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 ...

    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.

    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.

    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.

  19. QUALITATIVE STUDY ON THE FOUNDATIONS OF THE EXISTANCE OF THE EMPLOYEES’ PSYCHOLOGICAL CONTRACT. THE CASE OF THE ROMANIAN AUTOMOTIVE INDUSTRY

    Full Text Available The concept of psychological contract (PC, which describes the promises that play the role of obligations within the employment relation, has become during the last thirty years a major analysis tool in the organizational behaviour field. However, it has been mainly used, almost exclusively, in North-American or British organizational contexts. Only recently the researches on the psychological contracts have turned towards other parts of the world such as China, Southern America or India. Despite this opening towards new horizons, the Eastern European countries mainly remain unexplored from the psychological contract perspective. Certain well-known researchers (for example Rousseau and Coyle-Shapiro have even stated that the psychological contract simply doesn’t exist in this part of Europe. The present study which represents a part of the author’s doctoral thesis, demonstrates the opposite. Thus, our field research carried out in 2010 in two companies of the automotive industry in Romania on a sample of 31 participants, led us to conclude that the psychological contract is present in this country, too. By using a qualitative methodological approach inspired from the grounded theory, we have been able to notice that the foundations of the existence of the psychological contract are present in the analyzed sample. First of all, the employees benefit from contractual freedom, which allows them to negotiate the terms of their psychological contract and to begin or get out of an employment relation if it becomes unsatisfactory. Secondly, the employers benefit from a lot of flexibility when presenting the terms of the psychological contract to their employees. These two elements are derived from the market economy which is now being built in Eastern Europe and represent a significant change as compared to the employment relation characteristic to the centralized economy. Finally, our survey allowed us to seize, in the analyzed employment relation

    58 patients with a juvenile nasopharyngeal angiofibroma have been treated by a combined neuroradiological-surgical method. In the cases with smaller tumor extension, fed only by the external carotid arteries or with only slight participation of the internal carotid arteries, the external carotid arteries alone have been embolized using particles. In the cases with marked participation of the internal carotid arteries vessels were also embolized. In the first group there have been no complications and no recurrences. In the latter (31 cases) there have been three temporary minor complications and 11 recurrences.

    Full Text Available Abstract Introduction This case illustrates that superior semicircular canal dehiscence syndrome can be associated with a "pseudo"-conductive hearing loss, a symptom that overlaps with the clinical appearance of otosclerosis. Case presentation We present the case of a 48-year-old German Caucasian woman presenting with hearing loss on the left side and vertigo. She had undergone three previous stapedectomies for hearing improvement. Reformatted high-resolution computed tomographic scanning and the patient's history confirmed the diagnosis of concurrent canal dehiscence syndrome. Conclusion Failure of hearing improvement after otosclerosis surgery may indicate an alternative underlying diagnosis which should be explored by further appropriate evaluation.

    2007-08-01

    In this era of microscope-assisted endodontics, finding variations in root canal system anatomy is not uncommon. Operating microscopes combined with careful clinical examination and radiographic interpretation can aid the clinician to successfully treat cases with such internal anatomy. The understanding of this view enables the possible location of additional canals in any tooth requiring endodontic treatment. The present clinical article demonstrates a rare anatomical complexity in the mesial root of a mandibular first molar. Four independent root canal orifices were found in this root by clinical detection with the aid of a dental operating microscope. This case shows that additional canals can be located in any root undergoing endodontic treatment and clinicians should always be aware of aberrant internal anatomy.

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.

    The construction industry has hit a plateau in terms of safety performance. Safety climate is regarded as a leading indicator of safety performance; however, relatively little safety climate research has been done in the Canadian construction industry. Safety climate may be geographically sensitive, thus it is necessary to examine how the construct of safety climate is defined and used to improve safety performance in different regions. On the other hand, more and more attention has been paid to job related stress in the construction industry. Previous research proposed that individual resilience may be associated with a better safety performance and may help employees manage stress. Unfortunately, few empirical research studies have examined this hypothesis. This paper aims to examine the role of safety climate and individual resilience in safety performance and job stress in the Canadian construction industry. The research was based on 837 surveys collected in Ontario between June 2015 and June 2016. Structural equation modeling (SEM) techniques were used to explore the impact of individual resilience and safety climate on physical safety outcomes and on psychological stress among construction workers. The results show that safety climate not only affected construction workers' safety performance but also indirectly affected their psychological stress. In addition, it was found that individual resilience had a direct negative impact on psychological stress but had no impact on physical safety outcomes. These findings highlight the roles of both organizational and individual factors in individual safety performance and in psychological well-being. Construction organizations need to not only monitor employees' safety performance, but also to assess their employees' psychological well-being. Promoting a positive safety climate together with developing training programs focusing on improving employees' psychological health - especially post-trauma psychological

    Non-surgical management of older women with oestrogen receptor (ER)-positive operable breast cancer is common in the UK, with up to 40 per cent of women aged over 70 years receiving primary endocrine therapy. Although this may be appropriate for frailer patients, for some it may result in treatment failure, contributing to the poor outcomes seen in this age group. Wide variation in the rates of non-operative management of breast cancer in older women exists across the UK. Case mix may explain some of this variation in practice. Data from two UK regional cancer registries were analysed to determine whether variation in treatment observed between 2002 and 2010 at hospital and clinician level persisted after adjustment for case mix. Expected case mix-adjusted surgery rates were derived by logistic regression using the variables age, proxy Charlson co-morbidity score, deprivation quintile, method of cancer detection, tumour size, stage, grade and node status. Data on 17,129 women aged 70 years or more with ER-positive operable breast cancer were analysed. There was considerable variation in rates of surgery at both hospital and clinician level. Despite adjusting for case mix, this variation persisted at hospital level, although not at clinician level. This study demonstrates variation in selection criteria for older women for operative treatment of early breast cancer, indicating that some older women may be undertreated or overtreated, and may partly explain the inferior disease outcomes in this age group. It emphasizes the urgent need for evidence-based guidelines for treatment selection criteria in older women with breast cancer. © 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.

    In the case of emergency operating, operating staff usually are in the limit state of mind, so the operating mistake rate will go up sharply, and the disastrous accidents usually will happen at this moment. So to study and resolve the problem is very important and imperative. Basing on raising the reliability of man-machine system, the psychology and pathology of operating staff under the limit state and the behavior characteristic of operating staff in the emergency operation have been expounded here, and the operating staff's psychological gradation partitioned by foreign experts also has been introduced, and the influence factors of psychology and equipment which lead to the limit state of mind also have been analyzed. In addition, taking the emergency operation of the nuclear power plant as a example, The authors has studied the countermeasures to prevent the limit state from occurring, which includes countermeasures to environment effects, measures to improve the technical equipment and the measures that the operating staff should be taken

  17. Domains of pseudo-differential operators: a case for the Triebel-Lizorkin spaces

    Directory of Open Access Journals (Sweden)

    Jon Johnsen

    2005-01-01

    Full Text Available The main result is that every pseudo-differential operator of type 1, 1 and order d is continuous from the Triebel-Lizorkin space Fp,1d to Lp, 1≤p≺∞, and that this is optimal within the Besov and Triebel-Lizorkin scales. The proof also leads to the known continuity for s≻d, while for all real s the sufficiency of Hörmander's condition on the twisted diagonal is carried over to the Besov and Triebel-Lizorkin framework. To obtain this, type 1, 1-operators are extended to distributions with compact spectrum, and Fourier transformed operators of this type are on such distributions proved to satisfy a support rule, generalising the rule for convolutions. Thereby the use of reduced symbols, as introduced by Coifman and Meyer, is replaced by direct application of the paradifferential methods. A few flaws in the literature have been detected and corrected.

    To determine appropriate protocols for the identification and management of intra operative suspicious tissues during transsphenoidal surgery. Clinical data and pathological reports of 20 patients with intra-operative suspicious tissues during transsphenoidal surgeries were analyzed retrospectively. The methods for discriminating between adenoma and normal pituitary tissues were reviewed. The postoperative pathological reports revealed that adenoma and normal pituitary tissues coexisted in 9 samples, while 5 samples were identified as normal pituitary tissues, 2 as adenoma tissues, and 4 as other tissues. Adenomas were distinguished from normal pituitary tissues on the basis of intra-operative appearance, texture, blood supply and possible existence of boundary. If decisions are difficult to made during surgeries from the appearance of the suspicious tissues, pathological examinations are advised as a guidance for the next steps.

    2016-01-01

    College athletic departments have a responsibility to provide a safe environment for student-athletes; however, most colleges do not have a crisis management plan that includes procedures for displaced student-athletes or alternate facilities to perform athletic events. Continuity of operations planning ensures athletic programs are equipped to maintain essential functions during, or shortly after, a disruption of operations due to possible hazards. Previous studies have identified a lack of emergency preparedness and continuity planning in college athletic departments. The purpose of this article is to illustrate in detail one approach to disaster planning for college athletic departments, namely the Federal Emergency Management Agency (FEMA) continuity of operations framework. By adhering to FEMA guidelines and promoting a best practices model, athletic programs can effectively plan to address potential hazards, as well as protect the organization's brand, image, and financial sustainability after a crisis event.

  20. Kneading determinants and spectra of transfer operators in higher dimensions, the isotropic case

    CERN Document Server

    Baillif, M

    2003-01-01

    Transfer operators M_k acting on k-forms in R^n are associated to smooth transversal local diffeomorphisms and compactly supported weight functions. A formal trace is defined by summing the product of the weight and the Lefschetz sign over all fixed points of all the diffeos. This yields a formal Ruelle-Lefschetz determinant Det^#(1-zM). We use the Milnor-Ruelle-Kitaev equality (recently proved by Baillif), which expressed Det^#(1-zM) as an alternated product of determinants of kneading operators, Det(1+D_k(z)), to relate zeroes and poles of the Ruelle-Lefschetz determinant to the spectra of the transfer operators M_k. As an application, we get a new proof of a theorem of Ruelle on smooth expanding dynamics.

    2015-01-01

    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.

    A 75-year-old male presented with groin pain after an operation to treat lumbar spondylolisthesis (L5). Groin tenderness was localized to the medial border of the anterior superior iliac spine (ASIS). Radiographical and physical examination raised the suspicion of sacroiliac joint (SIJ) dysfunction. Injection of a painkiller into the SIJ relieved symptoms, including groin tenderness. Symptoms improved gradually, and finally disappeared after five SIJ injections. Groin pain has been reported as a referred symptom of SIJ dysfunction in 9.3-23% of patients. Prior to the patient undergoing surgery to treat lumbar spondylolisthesis, SIJ dysfunction had not been noted on physical examination. Long periods spent in the abnormal posture due to lumbar spondylolisthesis induced SIJ stress. After the operation, an improvement in daily activity actually increased stress on the SIJ, resulting in SIJ dysfunction. Certain pathologies, including SIJ dysfunction, should be considered as residual symptoms after operations for lumbar spinal diseases.

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.

    National differences exist in the outcome of elective abdominal aortic aneurysm (AAA) repair. The role of case mix variation was assessed based on an international vascular registry collaboration. All elective AAA repairs with aneurysm size data in the Vascunet database in the period 2005-09 were included. AAA size and peri-operative outcome (crude and age adjusted mortality) were analysed overall and in risk cohorts, as well as per country. Glasgow Aneurysm Score (GAS) was calculated as risk score, and patients were stratified in three equal sized risk cohorts based on GAS. Predictors of peri-operative mortality were analysed with multiple regression. Missing data were handled with multiple imputation. Patients from Australia, Finland, Hungary, Norway, Sweden and the UK (n = 5,895) were analysed; mean age was 72.7 years and 54% had endovascular repair (EVAR). There were significant variations in GAS (lowest = Finland [75.7], highest = UK [79.4], p for comparison of all regions 82. Of those with a GAS >82, 8.4% of men and 20.8% of women had an AAA case selection for elective AAA repair, including variations in AAA size and patient risk profile. These differences partly explain the variations in peri-operative mortality. Further audit is warranted to assess the underlying reasons for the regional variation in case-mix.

    The paper is concerned with the Mathieu-type differential equation u ″ =−A 2 u+εB(t)u in a Hilbert space H. It is assumed that A is a bounded self-adjoint operator which only has an absolutely continuous spectrum and B(t) is almost periodic operator-valued function. Sufficient conditions are obtained under which the Cauchy problem for this equation is stable for small ε and hence free of parametric resonance. Bibliography: 10 titles

    To study on relationship between diverse handling time following onset and clinical prognosis of cases with Bell palsy. Two hundred and sixteen cases with Bell palsy, who were admitted in our department between Jun. 2006 and Dec. 2009, were collected and divided into 6 groups according to disease time: 1-2 months, > 2 - 3 months, > 3 - 4 months, > 4 - 5 months, > 5 - 6 months, and > 6 months. Cases in all groups received subtotal course decompression of facial nerve and other compound treatment, and the relationship between handling timing and clinical prognosis were compared. It was found that the difference of prognosis and handling timing was statistically significant, after comparison between all groups with Facial Grading Standards (H-B) as the standard to assess prognosis. Clinical prognosis of cases with Bell palsy was related to alternative handling time, and subtotal course decompression of facial nerve was recommended to be performed as early as possible for those cases who were irresponsive after conservative treatment for one month.

    2004-01-01

    We recently observed a case of presumed irradiation-induced malignant fibrous histiocytoma (MFH), which developed 11 years after postoperative chemoradiotherapy for residual rectal cancer. A 65-year-old female underwent chemoradiotherapy for the residual tumor on the sacrum after abdominoperineal resection for rectal cancer in 1991. She showed no evidence of local recurrence or distant metastasis. Biopsy and MRI in 2002 suggested a retroperitoneal malignant tumor associated with invasion of the uterus and the sacrum, and the patient subsequently underwent surgery. Histopathologically the tumor was MFH. This case was considered to be an irradiation-induced secondary malignant tumor, according to the criteria developed by Arlen et al. In elderly patients and cases that underwent chemoradiotherapy, the latency period of irradiation-induced secondary malignant tumor tends to be shorter. If the progress of postoperative adjuvant chemotherapy increases the number of long-term surviving cases in the future, the incidence of irradiation-induced secondary malignant tumor will increase. It is therefore necessary to survey these cases over a longer period of time after surgery. (author)

  12. Varieties of Fame in Psychology.

    Science.gov (United States)

    Roediger, Henry L

    2016-11-01

    Fame in psychology, as in all arenas, is a local phenomenon. Psychologists (and probably academics in all fields) often first become well known for studying a subfield of an area (say, the study of attention in cognitive psychology, or even certain tasks used to study attention). Later, the researcher may become famous within cognitive psychology. In a few cases, researchers break out of a discipline to become famous across psychology and (more rarely still) even outside the confines of academe. The progression is slow and uneven. Fame is also temporally constricted. The most famous psychologists today will be forgotten in less than a century, just as the greats from the era of World War I are rarely read or remembered today. Freud and a few others represent exceptions to the rule, but generally fame is fleeting and each generation seems to dispense with the lessons learned by previous ones to claim their place in the sun. © The Author(s) 2016.

    2015-03-01

    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.

    2018-03-01

    Full Text Available Optimal operation of reservoirs is very essential for water resource planning and management, but it is very challenging and complicated when dealing with climate change impacts. The objective of this paper was to assess existing and future hydropower operation at the Tekeze reservoir in the face of climate change. In this study, a calibrated and validated Soil and Water Assessment Tool (SWAT was used to model runoff inflow into the Tekeze hydropower reservoir under present and future climate scenarios. Inflow to the reservoir was simulated using hydro-climatic data from an ensemble of downscaled climate data based on the Coordinated Regional climate Downscaling Experiment over African domain (CORDEX-Africa with Coupled Intercomparison Project Phase 5 (CMIP5 simulations under Representative Concentration Pathway (RCP4.5 and RCP8.5 climate scenarios. Observed and projected inflows to Tekeze hydropower reservoir were used as input to the US Army Corps of Engineer’s Reservoir Evaluation System Perspective Reservoir Model (HEC-ResPRM, a reservoir operation model, to optimize hydropower reservoir release, storage and pool level. Results indicated that climate change has a clear impact on reservoir inflow and showed increase in annual and monthly inflow into the reservoir except in dry months from May to June under RCP4.5 and RCP8.5 climate scenarios. HEC-ResPRM optimal operation results showed an increase in Tekeze reservoir power storage potential up to 25% and 30% under RCP4.5 and RCP8.5 climate scenarios, respectively. This implies that Tekeze hydropower production will be affected by climate change. This analysis can be used by water resources planners and mangers to develop reservoir operation techniques considering climate change impact to increase power production.

  3. Collective Psychological Ownership and Intergroup Relations.

    2017-11-01

    Whereas much social psychological research has studied the in-group and out-group implications of social categorization and collective identity ("we"), little research has examined the nature and relevance of collective psychological ownership ("ours") for intergroup relations. We make a case for considering collective psychological ownership as an important source of intergroup tensions. We do so by integrating theory and research from various social sciences, and we draw out implications for future social psychological research on intergroup relations. We discuss collective psychological ownership in relation to the psychology of possessions, marking behavior, intergroup threats, outgroup exclusion, and in-group responsibility. We suggest that the social psychological processes discussed apply to a range of ownership objects (territory, buildings, cultural artifacts) and various intergroup settings, including international, national, and local contexts, and in organizations and communities. We conclude by providing directions for future research in different intergroup contexts.

    2014-07-01

    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

    Objective: The purpose of the present study was to assess the feasibility, success, and safety of the transradial approach (TRA) for diagnostic coronary angiography. Study Design: Descriptive study. Place and Duration of Study: The study was carried out in Armed Forces Institute of Cardiology- National Institute of Heart Diseases (AFIC-NIHD) over a period of ten months from June 2009 to March 2010. Patients and Methods: We collected data of 500 consecutive patients who underwent coronary catheterization by the transradial approach. Transradial access was performed only if the Allen's test was normal (positive). Patients with previous CABG or requiring right heart catheterization were excluded from this study. Study endpoints included procedure success rate, vascular complications at access site, and major adverse cardiac and cerebrovascular events during hospitalization. Results: Mean age of the patients was 52 years (range 33-77 yrs) and 72.8% (n= 364) were men and 27.2% (n=136) were females. The vast majority of cases (98.4%) were elective. The right radial artery was used in 98% of cases. Procedural success was achieved in 90.6% cases (453/500). No case of vascular complications such as major access site bleeding, vascular perforation, radial artery occlusion, forearm ischemia, compartment syndrome or MACE was observed. Conclusion: Transradial access for coronary angiography is a safe, effective and elegant alternative to trans femoral access. (author)

    To describe the administration of local anesthetic through wound soaker catheters for post-operative veterinary patients and to characterize complications. Retrospective study of hospital records. Records of patients in which a wound soaker catheter was placed post-operatively between November 1, 2004 and July 1, 2006 at a veterinary teaching hospital. Records in which a limb amputation was performed between January 1, 2002 and August 1, 2007 and in which a wound soaker catheter was not placed were reviewed for historic control. A total of 56 cases were identified in which a wound soaker catheter was placed post-operatively including 52 dogs, 2 cats, and 2 goats. Twenty canine cases were identified in which limb amputation was performed and no wound soaker catheter was placed. The majority of surgical procedures for which a wound soaker catheter was placed included thoracic limb amputation (46.4%) and pelvic limb amputation (35.7%). Wound soaker catheters remained in place for an average of 1.6 +/- 0.5 days. Feline and caprine patients received intermittent bupivacaine boluses every 6 hours. Canine patients received continuous lidocaine infusions. Complications included disconnection of the catheter from the infusion (7.7%), one seroma, and one suspected lidocaine neurotoxicity. Incisional infections were noted in 3/56 (5.3%) limb amputations with wound soaker catheters placed which was not higher than the incisional infection rate found in the historic control cases 3/20 (15%). Use of the wound soaker catheter was a viable means of providing local analgesia in post-operative veterinary patients. Studies are needed to evaluate efficacy of pain management, and to further investigate techniques for catheter placement and maintenance which may help to optimize the analgesia achieved using this technique.

    2018-04-01

    The Kraus form of the completely positive dynamical maps is appealing from the mathematical and the point of the diverse applications of the open quantum systems theory. Unfortunately, the Kraus operators are poorly known for the two-qubit processes. In this paper, we derive the Kraus operators for a pair of interacting qubits, while the strength of the interaction is arbitrary. One of the qubits is subjected to the x-projection spin measurement. The obtained results are applied to calculate the dynamics of the entanglement in the qubits system. We obtain the loss of the correlations in the finite time interval; the stronger the inter-qubit interaction, the longer lasting entanglement in the system.

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

    2004-04-01

    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.

    1972-01-01

    A combined philosophical and social psychological study of over 40 of the Apollo moon Scientists reveals that the Orthodox or Received View of Scientific Theories is found wanting in several respects: (1) observations are not theory-free; (2) scientific observations are not directly observable; and (3) observations are no less problematic than theories. The study also raises some severe criticisms of distinction between the context of discovery and the context of justification. Not only does this distinction fail to describe the actual practice of science but even more important it has the dangerous effect of excluding some of the strongest lines of evidence which could most effectively challenge the distinction. The distinction is harmful of efforts to found interdisciplinary theories and philosophies of science.

    The degree of holding temperature and time play a major role in nano-case treatment of cutting tools which immensely contributed to its performance during machining operation. The objective of this research work is to carryout comparative study of performance of nano-case treatment tools developed using low and medium carbon steel as work piece. Turning operation was carried out under two different categories with specific work piece on universal lathe machine using HSS cutting tools 100 mm × 12mm × 12mm that has been nano-case treated under varying conditions of temperatures and timeof 800,850, 900, 950°C and 60, 90, 120 mins respectively. The turning parameters used in evaluating this experiment were cutting speed of 270, 380 and 560mm/min, feed rate of 0.15, 0.20 and 0.25 mm/min, depth of cut of 2mm, work piece diameter of 25mm and rake angle of 7° each at three levels. The results of comparative study of their performances revealed that the timespent in the machining of low carbon steel material at a minimum temperature and time of 800°C, 60 mins were1.50, 2.17 mins while at maximum temperature and time of 950°C, 120 mins were 1.19, 2.02 mins. It was also observed that at a corresponding constant speed of 270,380 and 560mm/min at higher temperature and time, a relative increased in the length of cut were observed. Critical observation of the result showed that at higher case hardening temperature and time (950°C/120mins), the HSS cutting tool gave a better performance as lesser time was consumed during the turning operation.

    The objective of the study was to reveal the way we treat vaginal mesh complications in a trained referral center. This is a retrospective review of all patients who underwent surgical removal of transvaginal mesh for mesh-related complications during a 5-year period. Eighty-three patients underwent 104 operations including 61 complete mesh removal, 14 partial excision, 15 section of sub-urethral sling, and five laparoscopies. Main indications were erosion, infection, granuloma, incomplete voiding, and pain. Fifty-eight removals occurred more than 2 years after the primary mesh placement. Mean operation time was 21 min, and there were two intraoperative and ten minor postoperative complications. Stress urinary incontinence (SUI) recurred in 38% and cystocele in 19% of patients. In a trained center, mesh removal was found to be a quick and safe procedure. Mesh-related complications may frequently occur more than 2 years after the primary operation. Recurrence was mostly associated with SUI and less with genital prolapse.

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

    2015-08-01

    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.

    Low Level radioactive Waste (LLW) at the Savannah River Site at Aiken, South Carolina, has traditionally been disposed of using engineered trenches in accordance with the guidelines and technology existing at the time. Recently, subgrade concrete vaults known as E-Area Vaults (EAV) have been constructed at SRS. The EAV project is a comprehensive effort for upgrading LLW disposal at SRS based on meeting the requirements of current Department of Energy (DOE) Orders, and addressing more stringent federal and state regulations. The EAV is a first of its kind state-of-the-art facility designed and built in the United States to receive LLW. Westinghouse Savannah River Company (WSRC) conducted an Operational Readiness Review (ORR) of the vaults prior to startup. The objective of the EAV ORR was to perform a comprehensive review of the operational readiness of the facilities per DOE guidelines including Defense Nuclear Facilities Safety Board (DNFSB) recommendations. This review included assessing construction of the vaults as per design, adequate approved procedures, and training of all the personnel associated with the facility operations. EAV ORR incorporated the lessons learned from other DOE ORRs, included DNFSB recommendations, used a graded approach, and utilized subject matter experts for each functional area of assessment

    The business case for climate protection activities is like a road map, indicating the right direction to go in. It estimates how long it will take to achieve desired results and highlights possible obstacles. Triple bottom line accounting considers all economic, environmental, and social factors of any given project. It is used by municipal governments to create these road maps. Sound fiscal management is addressed by clearly showing how to reduce costs, improve service delivery, create jobs and support local industries, while also protecting human health and the environment. For example, money can be saved and air pollution can be reduced by reducing energy consumption in a municipal building. Staff absenteeism can be reduced through improved air quality. The Federation of Canadian Municipalities has introduced a Partners for Climate Protection (PCP) initiative which guides municipal governments through steps leading to the development of a business case. 21 refs.

    2006-01-01

    This article is the chapter 6 of this book. It deals with the organization implemented by a nuclear operator and its suitability in warranting the safety of his facilities. An analysis approach has been defined which takes into consideration the formal aspect of the rules, structures and resources implemented by the organization, and which considers also the operational aspect through the collective activity of actors. The operation dynamics of the organisation has been approached through retrospective case studies aiming at understanding, from actors' contributions to the processing of events, how the characteristics of the organization were representing resources or constraints for the actors. This approach of organization through case studies must be put forward in the present day debate about cognitive ergonomics in sociology of organizations and in management. Several works try to put in relation the activity of 'front line' actors with the decisions and orientations taken at the strategic level. This supposes that one can combine an analysis of actors' activity integrating their point of view and and analysis of the structures and resources that are supplied to them by the organization.

    Four noble truths as preached by Buddha are that the life is full of suffering (Duhkha), that there is a cause of this suffering (Duhkha-samudaya), it is possible to stop suffering (Duhkha-nirodha), and there is a way to extinguish suffering (Duhkha-nirodha-marga). Eight fold Path (astangika-marga) as advocated by Buddha as a way to extinguish the sufferings are right views, right resolve/aspiration, right speech, right action/conduct, right livelihood, right effort right mindfulness and right concentration. Mid-twentieth century saw the collaborations between many psychoanalysts and Buddhist scholars as a meeting between "two of the most powerful forces" operating in the Western mind. Buddhism and Western Psychology overlap in theory and in practice. Over the last century, experts have written on many commonalities between Buddhism and various branches of modern western psychology like phenomenological psychology, psychoanalytical psychotherapy, humanistic psychology, cognitive psychology and existential psychology. Orientalist Alan Watts wrote 'if we look deeply into such ways of life as Buddhism, we do not find either philosophy or religion as these are understood in the West. We find something more nearly resembling psychotherapy'. Buddha was a unique psychotherapist. His therapeutic methods helped millions of people throughout the centuries. This essay is just an expression of what little the current author has understood on Buddha philosophy and an opportunity to offer his deep tribute to one of the greatest psychotherapists the world has ever produced!

    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.

Ons het die moontlikheid dat ’n deel van die vragmotorvloot swerwend in die geslote ruimtelike roete-network moet opereer, ondersoek. Dit is in teenstelling met die tradisionele vaste toedeling van vragmotors aan roetes. Besluitnemingreëls vir swerwende en vaste-roete vragmotors is ontwikkel, en die gehalte van die reëls is met diskrete simulasie en vier prestasiemaatstawwe evalueer.

    Ons het bevind dat die vervoeronderneming ’n bedryfsbeleid behoort te aanvaar wat toelaat dat ten minste 50% van die vloot swerf, terwyl hierdie swerwende vragmotors voertuie volgens spesifieke reëls by oplaaipunte moet kies.

  11. Analysis to verify effectiveness of alternative cooling method in case of loss of RHR function during mid-loop operation

    International Nuclear Information System (INIS)

    Nagae, Takashi; Tamaki, Tomohiko; Murase, Michio; Ayano, Teruyoshi

    2003-01-01

    In the mid-loop operation during shutdown of the pressurized water reactor (PWR) plant, the core decay heat is cooled by the residual heat removal (RHR) system. In the case of loss of the RHR function, core cooling is achieved by reflux cooling through the steam generator (SG) when the reactor coolant system (RCS) is closed, or by gravity injection of water from the refueling water storage pit (RWSP) when a large opening is present in the RCS. However, it is uncertain whether core cooling can be achieved by these alternative cooling methods, if the opening is not large enough in the RCS. In this study, the effectiveness of the reflux cooling through the SG and the gravity injection of water from the RWSP in the mid-loop operation three days after shutdown was investigated by using RELAP5/MOD3.2 with a plant model representing a typical 4-loop PWR plant in Japan, assuming that two bases of the pressurizer safety valves were removed. As a result, it was verified that in the case of a combination of the reflux cooling by through the SG and gravity injection of water from the RWSP, the time until the core was uncovered with water extended about an hour from that in the case of no cooling method.

    Children with Marfan syndrome rarely undergo surgery for annuloaortic ectasia and aortic regurgitation in the first decade. A 7-year-old girl presented with congestive heart failure due to severe aortic regurgitation associated with annuloaortic ectasia (6 cm). She also had funnel chest. She underwent a Bentall operation and sternal turn-over with a satisfactory result. Since the aortic valve cusps had rolled edges, the aortic valve was not spared. Histology of the aortic valve cusps showed myxoid degeneration and fragmentation of elastic fibers.

    Construction work involves significant physical, mental, and temporal task demands. Excessive task demands can have negative consequences for safety, errors and production. This exploratory study investigates the magnitude and sources of task demands on a concrete operation, and examines the effect of the production practices on the workers' task demands. The NASA Task Load Index was used to measure the perceived task demands of two work crews. The operation involved the construction of a cast-in-place concrete building under high schedule pressures. Interviews with each crew member were used to identify the main sources of the perceived demands. Extensive field observations and interviews with the supervisors and crews identified the production practices. The workers perceived different level of task demands depending on their role. The production practices influenced the task demands in two ways: (1) practices related to work organization, task design, resource management, and crew management mitigated the task demands; and (2) other practices related to work planning and crew management increased the crew's ability to cope with and adapt to high task demands. The findings identify production practices that regulate the workers' task demands. The effect of task demands on performance is mitigated by the ability to cope with high demands.

    This study was initiated to integrate information and enterprise-wide healthcare delivery system issues specifically within an inpatient retail pharmacy operation in a U.S. community hospital. Six Sigma tools were used to examine the effects to an inpatient retail pharmacy service process. Some of the tools used include service blueprints, cause-effect diagram, gap analysis derived from customer and employee surveys, mistake proofing was applied in various business situations and results were analyzed to identify and propose process improvements and integration. The research indicates that the Six Sigma tools in this discussion are very applicable and quite effective in helping to streamline and integrate the pharmacy process flow. Additionally, gap analysis derived from two different surveys was used to estimate the primary areas of focus to increase customer and employee satisfaction. The results of this analysis were useful in initiating discussions of how to effectively narrow these service gaps. This retail pharmaceutical service study serves as a framework for the process that should occur for successful process improvement tool evaluation and implementation. Pharmaceutical Service operations in the U.S. that use this integration framework must tailor it to their individual situations to maximize their chances for success.

  18. NASA's Advanced Multimission Operations System: A Case Study in Formalizing Software Architecture Evolution

    Barnes, Jeffrey M.

    2011-01-01

    All software systems of significant size and longevity eventually undergo changes to their basic architectural structure. Such changes may be prompted by evolving requirements, changing technology, or other reasons. Whatever the cause, software architecture evolution is commonplace in real world software projects. Recently, software architecture researchers have begun to study this phenomenon in depth. However, this work has suffered from problems of validation; research in this area has tended to make heavy use of toy examples and hypothetical scenarios and has not been well supported by real world examples. To help address this problem, I describe an ongoing effort at the Jet Propulsion Laboratory to re-architect the Advanced Multimission Operations System (AMMOS), which is used to operate NASA's deep-space and astrophysics missions. Based on examination of project documents and interviews with project personnel, I describe the goals and approach of this evolution effort and then present models that capture some of the key architectural changes. Finally, I demonstrate how approaches and formal methods from my previous research in architecture evolution may be applied to this evolution, while using languages and tools already in place at the Jet Propulsion Laboratory.

    Peritonitis, which is one of the leading complications of peritoneal dialysis (PD) worldwide, severely affected morbidity and mortality of the PD patients. Although many efforts have been made to prevent PD-related peritonitis, it seems impossible to prevent it completely. Many causes have been reported to lead to peritonitis, and contamination during bag exchange is one of the important risk factors for peritonitis. Here, we introduce an operating vehicle, which we invented to provide a sterile and safe space for bag exchange. A single-center, retrospective, case-control study was undertaken to determine whether this operating vehicle has a protective role in preventing peritonitis. In total, 462 continuous ambulatory peritoneal dialysis patients were included in this study from October 2014 to March 2017. According to their personal will, these patients chose to use operating vehicle or traditional method during their bag exchange. The demographic, clinical and laboratory data of these patients in the two groups were collected, analyzed and compared. Of 462 patients with home dialysis, operating vehicle group consisted of 61 patients, and control group consisted of 401 patients. In the control group, over 677 patient-years, peritonitis occurred in 69 of 401 patients (17.2%), while in the operating vehicle group, over 60 patient-years, only 4 of 61 patients (6.6%) had episodes of peritonitis. The number of patients suffered from peritonitis was significantly decreased in the operating vehicle group (P = 0.034). Besides, there were a total of 99 episodes of peritonitis, and the rate was 1 episode every 7.2 patient-years in control group and 1 episode every 12 patient-years in the operating vehicle group. There was significant difference between the two groups (0.013). Positive dialysate cultures were obtained in majority of the peritonitis episodes (60.6%). Operating vehicle might help to reduce PD-related peritonitis by preventing contamination during bag

Encapsulated in our acronym is a proposal to have a synthetic approach to social psychological research, in which qualitative methods are augmentative to quantitative ones, qualitative methods can be generative of new experimental hypotheses, and qualitative methods can capture experiences that evade experimental reductionism. We remind social psychological researchers that psychology was founded in multiple methods of investigation at multiple levels of analysis. We discuss historical examples and our own research as contemporary examples of how a SAGE model can operate in part or as an integrated whole. The implications of our model are discussed.

    Full Text Available Intravascular absorption of distending media may complicate operative hysteroscopy. Consequences differ according to type, amount and speed of absorption of the distending media. We report a case of intravascular absorption of more than one liter of 1.5% glycine. A 36 years old female developed metabolic acidosis, hyponatremia and hypocalcemia during operative hysteroscopy scheduled for resection of a uterine fibroid. Serum sodium reached down to 119 mmol/l and ionized calcium to 0.898 mmol/l. Serial estimations of arterial blood gases and serum electrolytes were followed. Management was successful in preventing serious side effects. Meticulous monitoring of distending media input/output balance remains the cornerstone in prevention of intravascular absorption.

    The purpose of this case study was to optimise design, operation and maintenance guidelines, and to assess the water treatment potential of a storm water pond system after 15 months of operation. The system was based on a combined silt trap, attenuation pond and vegetated infiltration basin. This combination was used as the basis for construction of a roof water runoff system from a single domestic property. United Kingdom Building Research Establishment and Construction Industry Research and Information Association, and German Association for Water, Wastewater and Waste design guidelines were tested. These design guidelines failed because they did not consider local conditions. The infiltration function for the infiltration basin was logarithmic. Algal control techniques were successfully applied, and treatment of rainwater runoff from roofs was found to be largely unnecessary for recycling (e.g., watering plants). However, seasonal and diurnal variations of biochemical oxygen demand, dissolved oxygen and pH were recorded.

    Complex planning procedures often amplify the difference in investment time between generation and transmission. In this work we consider a transmission project in Italy and, relying on a recently proposed methodology, we compare costs and benefits of anticipating the planning process before the connection of new power plants becomes certain. Whereas the system faces lower congestion costs if the network is reinforced immediately, anticipation constitutes a sunk cost in case generation is not built. For realistic load and generation scenarios, anticipation costs, as well as differences in investment times, our results indicate that anticipation is the most efficient choice for a relatively low connection probability. Analyses of this sort are particularly relevant in light of the increasing complexity of public engagement processes and of the remarkable growth in renewable generation. - Highlights: • Delays in transmission investments can increase congestion costs. • Anticipating a transmission upgrade before a generator connects has costs/benefits. • Case study: real-life transmission project in the North of Italy. • Anticipation is the efficient choice under several scenarios

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.

    Reprocessing is a high-tech industry that works. An impressive effort of R and D, industrial deployment and operational experience has been accumulated by COGEMA and BNFL, leading these companies to offer a commercial service which is the only proper management of spent fuel and waste that is both technically demonstrated and qualified by the safety authorities of European and overseas countries. Reprocessing, as every technology-based industry will continue to progress in the future. Recycling the fissile materials reclaimed from spent fuel: uranium and plutonium, is the complementary and indispensable last link to effectively close the fuel cycle and control in particular the production of plutonium and other long-lived actinides. This paper will describe the state of development attained in France and Great Britain and will underline the main advantages of the reprocessing/recycling strategy

    A forty-four-year-old man with a clinical diagnosis of diabetes melitus and severe obesity (height 170 cm, weight 108 kg) was admitted to the hospital on 12th January 1995 because of acute myocardial infarction, and on 21st January, he was referred to our hospital with sudden onset of shock, bradycardia, loss of consciousness in spite of having recovered well from myocardial infarction. The echocardiography and pulmonary arteriography revealed a pulmonary embolism and a tumor in the right atrium. Administration of tissue plasminogen activator (TPA) was not sufficiently effective. An emergency operation (pulmonary arteriotomy, right atriotomy, milking of bilateral lungs) with cardiopulmonary bypass revealed a massive consecutive thrombus, which occupied the right atrium, right ventricle and bilateral pulmonary artery. The postoperative course was uneventful.

    For almost two decades, there has been a global trend towards the deregulation and the liberalisation of electricity markets. Previously, national or regional monopolistic utility companies provided services along the entire supply chain of electricity supply: Beginning with the operation of power plants and thus the generation of electricity, continuing through the development and the operation of transmission and local distribution grids, to the connection points. Since all assets belonged to the utility company, they could easily access generation units in order to provide balancing power for the safe and reliable operation of the electricity networks. With the objective of a more efficient and cheaper electricity supply by enabling competition, European Directive 96/92/EC (repealed by 2003/53/EC) enacted so-called ''unbundling'' which meant the break-up of utility companies as full service suppliers into the three service oriented entities; for electricity generation, transmission and supply. Whereas previously a single utility company provided the balancing of the electricity grid with its own assets, as a consequence of the directive, markets developed for the provision of diverse technical services. As long as the utility companies provided these services on their own, technical rather than economic aspects prevailed in their investment decisions. With the establishment of open markets for primary, secondary and tertiary reserve power, commercial interfaces had been established which force the respective specialised market actor to investment decisions driven primarily by economic aspects. At nearly the same time - around two decades ago, the first renewable energy systems (RES) provided electricity to public grids. In the 1990's their share of the overall electricity mix was negligible, but since the beginning of the new millennium more and more countries recognised the ecological and economic advantages of RES and established incentive systems for their

    Full text: The lessons learned approach being followed at the Fast Flux Test Facility is to have domain experts in each subject area develop a short write-up or report on each lesson learned. Each lesson learned write-up is on the order of 4–6 pages. Longer reports can be developed as needed. Each lessons learned summary discusses the problem and the resolution method employed to address the problem, and also tries to capture the essential “tacit knowledge” associated with each topic in a focused manner. All lessons learned write-ups are supported by more detailed documents. For example, references of more detailed reports are generally included, where available. Topics are selected as those most likely to apply to future design or operating problems. This lessons learned approach has been successful in capturing essential tacit knowledge about key events in FFTF history and providing a context for interpreting the existing data and references.

    An outbreak of respiratory disease occurred in a central Alberta veal operation, after production capacity had been increased fourfold. Mortality rate reached 24.6% despite agressive antibiotic therapy. A review of the records revealed a cyclical disease pattern in each room. Weekly cleaning of occupied calf rooms was correlated with the disease pattern. Aerosols generated by a high pressure sprayer appeared to trigger transmission of respiratory pathogens in malnourished neonatal calves. Disease occurrence decreased and profitability increased sixfold after the introduction of the following measures: 1) discontinuing the use of the high pressure washer in the occupied calf rooms, 2) feeding calves a better quality milk replacer with supplemental milk for the poorest calves, 3) sale-yard calf purchases were abandoned in favor of direct buying.

    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.

    Liver is the most frequently injured organ upon abdominal trauma. We present a group of patients with blunt hepatic trauma who were managed without any invasive diagnostic tools and/or surgical intervention. A total of 80 patients with blunt liver injury who were hospitalized to the general surgery clinic or other clinics due to the concomitant injuries were followed non-operatively. The normally distributed numeric variables were evaluated by Student's t-test or one way analysis of variance, while non-normally distributed variables were analyzed by Mann-Whitney U-test or Kruskal-Wallis variance analysis. Chi-square test was also employed for the comparison of categorical variables. Statistical significance was assumed for phepatic trauma seems to be the gold standard.

  19. Impacts of Base-Case and Post-Contingency Constraint Relaxations on Static and Dynamic Operational Security

    Science.gov (United States)

    Salloum, Ahmed

    Constraint relaxation by definition means that certain security, operational, or financial constraints are allowed to be violated in the energy market model for a predetermined penalty price. System operators utilize this mechanism in an effort to impose a price-cap on shadow prices throughout the market. In addition, constraint relaxations can serve as corrective approximations that help in reducing the occurrence of infeasible or extreme solutions in the day-ahead markets. This work aims to capture the impact constraint relaxations have on system operational security. Moreover, this analysis also provides a better understanding of the correlation between DC market models and AC real-time systems and analyzes how relaxations in market models propagate to real-time systems. This information can be used not only to assess the criticality of constraint relaxations, but also as a basis for determining penalty prices more accurately. Constraint relaxations practice was replicated in this work using a test case and a real-life large-scale system, while capturing both energy market aspects and AC real-time system performance. System performance investigation included static and dynamic security analysis for base-case and post-contingency operating conditions. PJM peak hour loads were dynamically modeled in order to capture delayed voltage recovery and sustained depressed voltage profiles as a result of reactive power deficiency caused by constraint relaxations. Moreover, impacts of constraint relaxations on operational system security were investigated when risk based penalty prices are used. Transmission lines in the PJM system were categorized according to their risk index and each category was as-signed a different penalty price accordingly in order to avoid real-time overloads on high risk lines. This work also extends the investigation of constraint relaxations to post-contingency relaxations, where emergency limits are allowed to be relaxed in energy market models

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

    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.
